        "abstract": "Objective: To establish a simultaneous determination method of central nervous drugs including barbitals, benzodiazepines, phenothiozines and tricyclic antidepressants in human plasma. Methods: Drugs in plasma were extracted and purified by using X-5 resin solid phase extraction columns, followed by identification and quantitation using capillary GC-FID and GC-MS. Results: More than 20 drugs were simultaneously extracted from human plasma, and effectively separated in GC and TIC spectra. The correlation coefficient of standard curves was larger than 0.99, and relative standard differences (RSD) were less than 10% for most of the drugs. Under neutral extraction conditions, the lowest detection limits of barbitals were in the range of 2 ~ 5 \u03bcg/ml, in optimized conditions, they were reduced to 0.3 ~ 0.5 \u03bcg/ml. Conclusion: X-5 resin solid-phase extraction is fit for the simultaneous extraction and purification of large number of drugs in plasma, therefore it is satisfactory for rapid determination of overdose drugs clinically, when combined with capillary GC and GC-MS.",

Methods: ANP cDNA was transfected into Chinese hamster ovary (CHO) cells, which were encapsulated in polycarprolactone(PCL) tubes. The longterm survival of transfected CHO cells and the levels of ANP secreted were detected. Circadian rhythm of ANP secreted by encapsulated transfected cells was also studied, which was regulated by melatonin. Results: During culturing, the ANP level secreted by transfected CHO cells in 2 mL of culture medium within 24 hours could reach 210.3 ng/L in a 20 mm-long and 2 mm-diameter PCL tube. The section of ANP displayed a circadian variation: higher in daytime, but lower at night. The acrophase of circadian rhythm was 4: 15 but could be shifted to 7: 55 after melatonin management. Conclusion: ANP cDNA transfected CHO cells that encapsulated into PCL tube can secret ANP, which might be suitable for the future implantation into human body. Our research provides a new approach in the treatment of hypertension and CHF by ANP.",

        "abstract": "The adaptation of the endogenous rhythm of an organism to external cycles may influence the development of physiological processes in animals. Light not only synchronizes the circadian system, but also exerts profound direct effects: the immediate reduction of melatonin release at night-time and the inhibition of locomotor activity in nocturnal rodents after a light pulse are well-known examples, yet little is known about effects of different light/dark (LD) cycles on the level of corticosterone, growth hormone and growth rate. Mice were raised under different period length of LD cycle including LD5:5 (light: 5 h; dark: 5 h), LD12:12 (light: 12 h; dark: 12 h) and LD16:16 (light: 16 h; dark: 16 h) for four weeks. Mice in LD5:5 and LD16:16 groups manifested higher locomotor activity, plasma corticosterone and growth hormone concentrations and growth rate than the LD12:12 group. The results suggest that different LD cycles may affect many physiological processes including growth rate, food intake and hormones, and the change of growth rate in different LD cycles may be related to the level of corticosterone and growth hormone concentrations. The results also suggest that both the long-period LD cycle and short-period LD cycles can improve the growth of mice, but they disturbed the biorhythm stabilization and affected hormone secretion; in general, these conditions would not promote the animals' survival. \u00a9 2006 Taylor & Francis.",

The aqueous solubility of the model drugs (L-Histidine, Naproxen, Methotrexate) was measured in the presence of this kind of dendrimers at room temperature in PBS buffers at pH 6, 7 and 8. Results clearly confirmed that the solubility enhancement was due to presence of dendrimers at different pH compared to their corresponding aqueous solubility at different pH. The results indicated that the aspartate based dendrimers could be considered as an effective supplement of PAMAM dendrimers in solubility enhancement and drug delivery.

Targeting anticancer drug to the bone after systemic administration may provide both greater efficacy of treatment and less frequent administration. In this paper, a series of bone targeting Asp oligopeptides 5-fluorouracil conjugates have been synthesized in a convergent approach and well characterized by NMR and MS techniques. Their hydroxyapatite (HAP) affinity, drug release and cytotoxicity characteristics were evaluated in in vitro conditions. All the prodrugs were water soluble and exhibited high affinity to HAP .The efficient release of the active drug moiety occurring by the cleavage of different linkage in physiological conditions significantly reduced the number of viable human cancer cells. From in vivo distribution, we get these compounds with high bone-selectivity and long halflife. These results provided an effective entry to the development of new bone targeting chemotherapeutic drugs. \u00a9 2011 Elsevier Ltd. All rights reserved.",

To find a more effective way in NSAIDs dendritic prodrugs, in this paper, three different dendritic scaffolds of enzymatically cleavable naproxen conjugates have been synthesized in a convergent approach and well characterized by NMR and MS techniques. These self-immolative dendritic NISADs prodrugs programmed to release multiple molecules of the potent naproxen after a single enzymatic activation step, and in 50% human plasma, the drug released from the compound T3 reaching 47.3% after 24 h in vitro assay. Moreover, all prodrugs were also found to maintain more significant anti-inflammatory activity, no significant cytotoxicity against HEK293 cells and less degree of ulcerogenic potential in vivo than their monomeric counterpart naproxen. These results provided an effective entry to the development of new dendritic NSAIDs prodrugs. \u00a9 2013 Elsevier Ltd. All rights reserved.",

Chemical structures of the synthesized polymers were confirmed by <sup>1</sup>H nuclear magnetic resonance (<sup>1</sup>H NMR) and Fourier transform infrared assay (FTIR) and molecular weight determined by gel permeation chromatography (GPC). The copolymers were processed into nanoparticles for delivery of paclitaxel (PTX). In this work, the PTX-loaded nanoparticles were prepared by the emulsion-solvent evaporation method, and the physicochemical properties and cytotoxicity were investigated. The particle sizes of nanoparticles determined by dynamic light scattering measurements were around 70\u00a0nm. Transmission electron microscopy showed that the nanoparticles were spherical in shape. The results of in vitro release tests showed that the release profiles of PTX-loaded nanoparticles had a sustained drug release pattern, and PTX release from nanoparticles at pH 5.8 was much faster than that at pH 7.4. The drug release profiles were also fitted for mathematical models to analyze the release mechanism, and the Korsmeyer-Peppas model was found to be the best fit model, indicating a combined effect of diffusion and erosion mechanisms for drug release. The cytotoxicity based on 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay against human hepatic carcinoma HepG2 cells indicated that the GA-PEG-PBLA nanoparticles had low cytotoxicity and good biocompatibility. These results indicated that the GA-PEG-PBLA nanoparticles could be a novel candidate for liver-targeted delivery of poorly water-soluble anticancer drugs.",

In this paper, lysine dendrimers (G1-G3) were chosen as novel cell-penetrating carriers for anti-cancer drugs based on the internalization mechanism of cell-penetrating peptides and the characteristics of dendritic peptides. After labeling with fluorescein isothiocyanate (FITC), the cell-penetrable capacity of lysine dendrimers was certified by flow cytometric analysis. In a preliminary biological evaluation, the conjugates of lysine dendrimers and 5-fluorouracil showed the expected advantages: stable drug release, low toxicity to normal cells, and moderate inhibition of tumor cells. These results imply that cell-penetrable lysine dendrimers could be potential carriers in drug delivery of anti-cancer medicine. Cell-penetrable lysine dendrimers (G1-G3) were evaluated as carriers for the model drug 5-fluorouracil. As expected, these prodrugs showed stable drug release, low cytotoxicity to normal cells, and moderate inhibition of tumor cells. The preliminary biological evaluation results imply that lysine dendrimers are potential drug carriers with effective translocation and reduced cytotoxicity for anti-cancer drug delivery. \u00a9 2014 WILEY-VCH Verlag GmbH & Co.

The RGD-modified hybrid nanoparticles (RGD\u2013lpNPs) could overcome the poor water solubility of Cur to meet the requirement of intravenous administration and tumor active targeting. The obtained optimal RGD-lpNPs, composed of PLGA (poly(lactic-co-glycolic acid))\u2013mPEG (methoxyl poly(ethylene- glycol)), RGD\u2013polyethylene glycol (PEG)\u2013cholesterol (Chol) copolymers and lipids, had good entrapment efficiency, submicron size and negatively neutral surface charge. The core-shell structure of RGD\u2013lpNPs was verified by TEM. Cytotoxicity analysis demonstrated that the RGD\u2013lpNPs encapsulated Cur retained potent anti-tumor effects. Flow cytometry analysis revealed the cellular uptake of Cur encapsulated in the RGD\u2013lpNPs was increased for human umbilical vein endothelial cells (HUVEC). Furthermore, Cur loaded RGD\u2013lpNPs were more effective in inhibiting tumor growth in a subcutaneous B16 melanoma tumor model. The results of immunofluorescent and immunohistochemical studies by Cur loaded RGD\u2013lpNPs therapies indicated that more apoptotic cells, fewer microvessels, and fewer proliferation-positive cells were observed. In conclusion, RGD\u2013lpNPs encapsulating Cur were developed with enhanced anti-tumor activity in melanoma, and Cur loaded RGD\u2013lpNPs represent an excellent tumor targeted formulation of Cur which might be an attractive candidate for cancer therapy.",

The DNA-protein interactions between DNA fragments containing the conserved sequences in the 5\u2032 proximal region and nuclear proteins from different tissues of mouse were studied by means of gel-shift assay, and Southern-Western blot.

The scFv46 fragment could enhance the resistance of ASNase to trypsin proteolysis, with 70% of the initial ASNase activity present after the ASNase-scFv46 complex had been treated with trypsin for 30 min at 37\u00b0C, whereas little residual activity was detected without the scFv46 fragment. The scFv46 gene was cloned to an expression vector pET-21a and expressed at high levels (about 45% of total cell protein) in E. coli BL21 (DE3) as inclusion bodies. The refolded and purified scFv46 fragment was proved to protect ASNase, and the protective effect was further confirmed by SDS/PAGE. It was found that under optimum conditions of molar ratio of scFv to ASNase, incubation time and temperature, the residual activity of the AsNase-scFv46 complex could reach about 78% after treatment with trypsin for 30 min at 37\u00b0C. The results demonstrated that scFv fragments prepared by phage-antibody library technology could be used to protect target proteins.",

Methods: A case-control research was done in 31 cases of AIDP, 33 cases of AMAN and 132 health individual controls. DNA was extracted from peripheral blood leukocytes by improved fast saltingout. HLA-A, B antigens were typed by DNA-based technology, PCR-sequence specific primers (PCR-SSP) method. In determination of allelic pelymorphism by PCR amplification with SSP, oligonucleotide primers are designed to obtain amplification of specific alleles or groups of alleles. Assignment of alleles is based on the presence or absence of PCR amplified product, which may be detected by agarose gel electrophoresis. Results: On research of HLA-A, B alleles polymorphism, it showed that HLA-A33 frequency was increased significantly in AIDP patients [22.6% vs 4.5%, corrected probability (Pc) = 0.011]; related risk (RR) was 6.1; HLA-B15, B35 frequencies were increased (51.7% vs 20.8%, Pc = 0.015; 34.5% vs 6.9%, Pc = 0.000 8); RR was 4.1 and 7.1, respectively. Conclusions: There are different distribution of HLA-A, B alleles in AIDP and AMAN, two forms of GBS. AIDP susceptibility is associated with HLA-A33, while AMAN is with HLA-B15, B35.",

First of all, a rational representation for integrated features by virtue of complex vectors is given, i.e., two sets of feature vectors of a same sample are combined together by a complex vector. As a result, the feature space becomes a complex vector space rather than a real one. Then, to solve the problem of feature extraction in the integrated complex vector space, the theory of the complex uncorrelated linear discriminant analysis (ULDA) is developed. Based on this theory, a generalized ULDA method is proposed. This method is suitable for feature extraction in the complex integrated feature space. Finally, the method proposed in this paper is tested on Concordia University CENPARMI handwritten digit database and NUST603HW handwritten Chinese character database built in Nanjing University of Science and Technology. The experimental results indicate that after feature extraction using the proposed method, the recognition accuracy is increased significantly as well as the dimension of feature vector is reduced largely. Moreover, the experimental results also demonstrate that the proposed feature extraction method based on feature integration is more powerful and more efficient than the classical one.",

Then the nonlinear electric polarization due to torsion was analyzed and the problems of electric field in torsional effect of piezoelectric were converted inner and outer boundary value problems of partial differential equations according to the equivalent principle of electric field. So the connection between the torque and the polarized charges was established. An optimizing method for the sensitivity in detection of torsional effect was modified.

The key issues in FE modeling of long-span bridges for health monitoring and condition assessment has been studied by our group for several years. The FE models of the Tsing Ma Bridge (TMB) in Hong Kong and Runyang Yangtse Bridge (RYB) in Jiangsu have been developed respectively for the purpose of structural health assessment and installation of a structural health system on RYB. The result shows that the model for the purpose of health assessment should be developed on the basis of transition theory for linking elements between local-scale at material points and full-scale at the structural level. Model updating and validation are necessary for an accurate modeling of the complicated bridge structures. Some critical components are determined from the analysis of the structural response by using the FE model of TMB in full-scale, then the local FE models are developed and used to determine the behavior of hot-spot stress and fatigue accumulation at critical locations.",

To retrieve the images, the key is to get the shape features. In this paper, a new method for extracting shape features of trademarks is presented. Based on the theory of information, the method uses images' entropy and invariant moments to capture the shape and spatial information of images. The algorithm is easy and the experimental results show its invariability with respect to translation, scale and rotation of objects. What's more, it also has the noise invariance.",

The calorific power distribution was numerically simulated and the values of frequency-doubling crystal phase mismatching varying with the change of temperature were given. In experiment, double acousto-optic Q-switching were employed inside single Nd:YAG rod, high efficiency flat-concave intracavity-frequency-doubled resonance structure.

However, the wide application of MaPPM is only possible with the advent of high-performance parallel computers. The great size gap between solid particle and pseudo-particle makes MaPPM different from MD simulations during the parallelization process, which is the specialty and difficulty in this paper. The domain decomposition method is used in the parallel algorithm because of the great number of pseudo-particles in particle-fluid systems. The algorithm is also improved according to the specialty in MaPPM to reduce computation cost. The computation is conducted on COW (cluster of workstations) with different system sizes and various numbers of processors to test its performance. Computation results indicate that the new algorithm has high parallel efficiency and good scalability. The parallel implementation will help to make use of MaPPM in large-scale simulations of two-phase flow.",

Dynamic bit allocation is used according to different U/V modes of super-frames so as to reduce bit rate as well as improve speech quality.

What follows, Kernel Fisher Discriminant Analysis (KFDA) is performed on three classes of wavelet features. Three final discriminant feature vectors are obtained, from which a feature fusing method is developed. Finally, the experimental results on ORL face databases indicate that the proposed method is more effective than the current KFDA. And, more importantly, its consumed time in feature extraction is only one thirteenth of that of KFDA. Moreover, the experiments also demonstrate that this method is robust in uncontrolled lighting condition.",

Accordingly, a unified procedure of combining the finite element codes of full film lubrication and metal forming was developed for either steady or unsteady three-dimensional processes including axisymmetric and plane strain cases. The availability of the method was proved by the experiment of an axisymmetric stretch forming process. It showed that the precision of simulation can be enhanced substantially by the present method.

The fatigue damage evolution curves of the welded specimens were obtained by investigating the system frequency changes. The results show that the total fatigue life of the welded specimens are composed of two parts, the life corresponding to fatigue crack initiation and growth, being about 90% of the total life, and the period of fatigue crack propagation, being only 10% of the total life. Fatigue cracks develop in the shape of semi-ellipse, and the pattern of fatigue crack growth looks like headstand Y with the head pointing at the origin of the cracks.",

In this paper, a parallel algorithm for macro-scale pseudo-particle modeling based on spatial decomposition (SD) is presented. The parallel implementation utilizes MPI as the programming environment. Due to movement of particles during simulation, the parallelization of MaPPM may suffer from load imbalance and attendant performance degradation. Recursive Coordinate Bisection (RCB) is adopted to partition the whole computational domain in a dynamic fashion to balance the workload in processors. The Shift scheme is modified to meet the communication requirement in the dynamic partition. The parallel approach was applied to simulation of bubble behavior in gas-solid fluidized beds with different system sizes to test its performance. The computations were conducted on cluster of workstations (COW). Experimental results show that the algorithm has a good scalability. With dynamic load balancing (DLB), the parallel efficiency can be improved by up to 8%. To sum up, it was a successful implementation for the parallelization of macro-scale pseudo-particle modeling. \u00a9 2004 Elsevier Ltd. All rights reserved.",

In this paper, the role of different PMs for multi-scale modeling of complex flows is critically reviewed and possible development of PMs in this background is prospected, with the emphasis on pseudo-particle modeling (PPM). The performances of some different PMs are compared in simulations and new development in the fundamentals and applications of PPM is also reported, demonstrating PPM as a unique PM for multi-scale modeling.",

The difficulty in getting the voltage collapse point is that the system Jacobian matrix has a simple zero eigenvalue at the critical point, causing the Newton method failure in the neighborhood of the bifurcation point. Based on the circuit models of a power system and the theory of manifold transversality, the saddle-node bifurcation point is corresponding to the non-transversal intersection between the solution manifolds of injection equations and the linear network equations in the space spanned by the bus voltage and the injection current. This research studies the characteristics of the two solution manifolds and gives an algorithm based on the Newton algorithm for getting the non-transversal point, and it also can calculate the transversal point. \u00a9 2005 IEEE.",

As more and more filtering queries are registered in high-speed data stream management system, the processing efficiency becomes crucial. This paper presents an efficient query index structure based on decision tree. The index structure makes full use of predicate indices on single attributes, as well as the conjunction relationship between predicates in a single query. It is easy to integrate various predicate indices into this structure. How to select dividing attributes during construction is crucial to the performance of the index tree. Two dividing attribute selection algorithms are described. One is based on information gain (IG) and the other is based on estimated time cost (ETC). The latter takes some sample tuples as a training data set and is able to build more efficient trees. Our experiments demonstrate that. \u00a9 Springer-Verlag Berlin Heidelberg 2006.",

The implementation of the main module of this platform and relevant template library are introduced in the paper. Object-oriented programming and template techniques are adopted in the software development, and the codes are of good generality and extensibility. The software was tested in simulation of 3D air flow in stove hearth using the PPM method and in MD simulation of phase separation of two immiscible components in membrane.

To achieve this, the thresholding method employs a statistical process. The statistical analysis is performed on binary speckle images rather than on original grayscale speckle images. The binarization is performed by a thresholding technique. A fast algorithm of the thresholding method is developed which makes it acceptable in practice.

Fuzzy set theory could be seen as a generalization of classic set theory. In this paper, a digital speckle correlation method based on fuzzy logic (DSCMF) is proposed to measure the displacement of laser speckles. DSCMF is developed to improve performances of the digital speckle correlation method based on classic logic (DSCMC), at the same time keeping low computation simplicity. Fuzzy correlation between two images could be defined as an integral of membership of similarity between elements of two images. Membership function of similarity is defined to represent the distance of two values. An optical and analysis system was set up to verify DSCMF's validity.

The main goal of the test is to examine the effects of initial load and load history on the ultimate strength of strengthened reinforced concrete beams by externally bonded CFRP laminates. The main experimental parameters include different levels of sustaining load at the time of strengthening and load history. To explain the experimental results in quantitative terms, a theoretical model for flexural behavior of the strengthened reinforced concrete beam is also developed. Test results in the current study show that sustaining load levels at the time of strengthening have important influence on the ultimate strength of strengthened reinforced concrete beams. If the initial load is basically same, the ultimate strength of reinforced concrete beams strengthened with CFRP laminates is almost same regardless of load history at the time of strengthening. \u00a9 2005 Elsevier Ltd.

Methods: A case-control research was performed on 48 GBS patients and 58 healthy individuals as control group. Levels of TNFa in test and control subjects were determined by means of sandwich enzyme-linked immunosorbent assay (ELISA). A biallelic polymorphism at position -308 in the promoter region of TNF\u03b1 was screened by polymerase chain reaction (PCR) amplification and restriction fragment length polymorphism (RFLP) assay. Results: 1 The serum concentration of TNF\u03b1 was found significantly increased in GBS patients compared with that of healthy controls ((47.34 \u00b1 6.12) pg/ml in GBS vs. (21.18 \u00b1 5.24) pg/ml in healthy controls, P < 0.05). 2 In the research of TNF\u03b1 gene polymorphism, the frequencies the TNF2 allele increased significantly in GBS patients compared with those of healthy controls (20.83% in GBS vs. 5.17% in healthy controls, RR = 4.82, P < 0.05). 3 There were significant differences of TNF\u03b1 levels among the TNF1/1 group, TNF1/2 group and TNF2/2 group ((44.46 \u00b1 4.77) pg/ml, (50.76 \u00b1 2.86) pg/ml and (58.07 \u00b1 1.09 ) pg/ml, P < 0.05).

To analyze the change of platelet active factor (PAF)-platelet membrane glycoprotein in the production and development of cerebrovascular disease and further discover the relationship between them and promote the prevention and treatment of cerebrovascular disease. Data sources: The Medline database was searched for articles on the relationship of PAF and cerebrovascular disease published from January 1990 to December 2004 with the key words of \"Platelet activation, Platelet glycoprotein, Cerebral arterial thrombosis, Atherosclerosis\" in English, and the observational subjects were human. Meanwhile, China National Knowledge Infrastructure (CNKI) was also searched for literatures about blood platelet activation with cerebral arteriosclerosis and cerebral thrombosis published between January 1994 and December 2004 in Chinese with the key words of \"platelet membrane glycoprotein, cerebral arteriosclerosis, cerebral infarction\". Study selection: The data were selected firstly, and the literatures accorded with criteria were included, and then the full-texts were searched. Inclusive criteria: 1 Original work about structure, detective principle and how to work of platelet membrane glycoprotein in the process of blood platelet activation. 2 original work of quantitative detection of platelet membrane glycoprotein on diagnosis and prevention of cerebrovascular disease. Exclusive criteria: articles with repetitive research and literatures on other kinds of platelet membrane glycoprotein that had no relation with this study. Data extraction: Totally 64 literatures about detection of PAF and its relationship with cerebrovascular disease were collected. Articles with repetitive research or without study of platelet membrane glycoprotein were excluded. Nineteen papers were included, which composed of 3 articles on the structure and detective principle of platelet membrane glycoprotein, 1 paper on the relationship between blood platelet activation and cerebral arteriosclerosis, 12 literatures on the relationship between PAF and cerebral thrombosis, 1 article on the relationship between blood platelet activation and cardiovascular disease and 2 papers on application of receptor antagonist of platelet membrane glycoprotein. Data synthesis: The blood platelet activation played an important role in the process of onset and development of cerebrovascular disease. Because of the formation of atherosclerotic plaque, the factor accelerated the activation of blood platelet could not inverse, which made the blood platelet in the activated status for a long time. Clinical anticoagulation could decrease the activation of blood platelet to some degree, but could not eliminate fully the effect of factors inducing activation. The platelet membrane glycoprotein of activated blood platelet changed significantly as compared with the quiescent blood platelet, and expressed in a large number in blood platelet membrane, and became a molecule marker of activated blood platelet. With the profound study of molecular biology of platelet membrane glycoprotein and the clarification of molecule mechanism of thrombosis, the synthesis of receptor antagonist of new-type blood platelet membrane would instead or compensate the effects of aspirin and suppository, and promote the prevention and treatment of cerebrovascular disease. Conclusion: The activation of blood platelet plays an important role in thrombotic diseases. Thus, the study of activation of blood platelet as an early factor of thrombosis and infarction in cerebral vessels as well as exact determination of GP II b/III a, GP I b and GMP-140-its activated marker have crucial significance on detection of diagnosis, prevention and therapeutic efficacy of the onset of cerebrovascular disease.",

But meanwhile it brings the problem of shared resources contention among threads. In this paper, we make a comparison of processing performance and cache contention capabilities in SMT model among different state phases in protocol automata. We find that Load/Store functional unit within processor can make one bottleneck of protocol processing performance, and for stateful protocol processing thread has stronger cache contention capability when in connection building phase. This paper presents a new parallelism strategy, breaking the protocol finite state machine into sub-machines according to the performance characters of different state phases and running the sub-machines concurrently in logic processors. Simulation results show that this strategy can make threads use shared cache more friendly and obtain more performance improvement in SMT architecture. In real processors this strategy can improve performance by about 5%, comparing with the connection level parallelism.",

To improve the speed of this measurement method, a new speckle tracking method-digital speckle marginal correlation (DSMC) method is presented after the research of digital speckle correlation measurement (DSCM) method and speckle images characteristic. The speckle images pixel sum of every line and column is computed to make the light energy accumulated to the margin, and then uses only the two sequences to find the displacement of speckle images by correlation and interpolation method. And the displacement of speckle image reflects the distortion or displacement of objects. The theory and experiment proves that this method is feasible and it reduces computing time greatly without damaging the computing precision, because the precision of the measurement is mainly determined by the number of interpolation points and the synthesis noise of the digital speckle images themselves.",

We propose two efficient systolic arrays of multiply and accumulate (MAC) operation and we also describe the vector-vector and matrix-matrix multiplication that can be efficiently implemented by using the MAC arrays. The two systolic arrays have high performance (low time complexity, space complexity and latency) and consume smaller gate-area in comparison to other architectures. It is suitable for VLSI implementation for its regularity and modularity. \u00a9 2006 IEEE.",

Experiments show the method has the invariability with respect to translation, scaling and rotation. Besides, the features compromise local and global features of the image at the same time, therefore, the retrieval results match human visual percept well.",

        "abstract": "Intrusion detection is a critical component of secure information systems. Current intrusion detection systems (IDS) especially NIDS (Network Intrusion Detection System) examine all data features to detect intrusions. However, some of the features may be redundant or contribute little to the detection process and therefore they have great impact on the system performance. This paper proposes a lightweight intrusion detection model that is computationally efficient and effective based on feature selection and Maximum Entropy (ME) model. Firstly, the issue of identifying important input features is addressed. Since elimination of the insignificant and/or useless inputs leads to a simplification of the problem, therefore results to faster and more accurate detection. Secondly, classic ME model is used to learn and detect intrusions using the selected important features. Experimental results on the well-known KDD 1999 dataset show the proposed model is effective and can be applied to real-time intrusion detection environments.",

The multi-scale finite element modeling was first studied by using substructure method and the multi-point constraints. A multi-scale model of Tsing Ma Bridge (TMB) was then developed by using the design drawings and the proposed strategy on the basis of the software ABAQUS and the developed programs via the user interface. The model updating and verification were carried out based on the online data from the structural health monitoring system installed on TMB. The procedure for damage analysis using the developed model was proposed, in which locally deteriorating process at welded details of interconnects is able to account for the major effect of the damage and nonlinear influence on structural response. The calculated result shows that damage features can be successfully performed via multi-scale modeling and analysis; and fatigue damage accumulation on the weld details shows significantly local effect. The fatigue life obtained from the fully coupled calculation on stress and damage is shorter than that from the uncouple computation, which suggests that the significant interaction between the damage and the structural response should be considered in the structural damage analyses using the multi-scale numerical analysis.",

The conventional algorithms always need the scene characteristics, which makes the algorithms not widely used and automatically performed. An approach is presented that does not rely on any scene assumptions such as camera location and scene characteristics. Color information, texture information and spatial constraints are embedded to define the overall algorithm. Firstly, relevant areas are identified in each image. Then, the color distortion caused by shadow are calculated. Finally, the moving object and shadow are detected by using color distortion compensation and texture verification. The proposed algorithm is demonstrated on many kinds of outdoor video sequences. Moreover, the performance comparisons show that the proposed algorithm outperforms the conventional ones.",

Probabilistic characteristic of generator variables provide operators more comprehensive operating information and they are the base of the probabilistic transient stability analysis in multi-operating conditions. To some extent, expectations and covariances can describe the probabilistic distribution characteristics of these variables. Based on the operating curves of nodal injections and PV voltages and with the assumption that all generator variables obey the normal distribution, the expectation expressions and linear covariance expressions of generator variables are deduced according to the probabilistic load flow analysis and the basic property of numerical characteristics of random variables.

        "abstract": "It has been reported that the tumor necrosis factor (TNF)\u03b1 promoter polymorphism is associated with autoimmune disease and inflammatory disease. It has also been claimed that this polymorphism may affect TNF\u03b1 expression. We investigated the TNF\u03b1 -308 polymorphism and TNF\u03b1 levels in 79 unrelated Chinese patients with Guillain-Barr\u00e9 syndrome (GBS) and 78 healthy controls using PCR-RFLP and ELISA assay. Patients with GBS were divided into 2 subgroups, acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and acute motor axonal neuropathy (AMAN), based on electrophysiological information. We found that the TNF\u03b12 allele was associated with increased risk of GBS (OR = 1.876, 95% CI = 1.144-3.075, p = 0.008), particularly for AMAN, the main subtype (OR = 2.914, 95% CI = 1.412-6.015, p = 0.004), but there was no association between TNF\u03b1 polymorphism and AIDP. We also found that carriers of the TNF\u03b12 allele had significantly higher TNF\u03b12 levels than TNF\u03b11 homozygotes (p < 0.05). These data indicate that TNF\u03b1 promoter polymorphism is responsible for susceptibility to GBS, especially to AMAN. The TNF\u03b12 allele is associated with higher levels of TNF\u03b1.

This algorithm aims to minimize the control cost while recovering the feasibility of the power flow. The recovering process is transformed into a nonlinear programming problem which is solved in two steps, restoring solvability and restoring feasibility. The optimal load shedding method is used to regain power flow solutions under specified contingencies, while a modal analysis is made to determine the participation factors of each bus related to the key instability mode. These participation factors are used to determine a priority list for the optimal power flow tool to minimize the load shedding and re-dispatch of the active/reactive power generation. The primal-dual interior-point algorithm is applied to solving the integrated mixed-integer and nonlinear problem. The simulation results show that the modal analysis has reduced the dimensions of the problem and improved the converging speed, which is important for on-line real-time control.",

However, there still exist some unresolved and scarcely addressed problems such as the difficulties in obtaining adequate qualified attack data for the supervised classifiers to model the attack patterns, the data acquisition task is always time-consuming and greatly relies on the domain experts, etc. Based on these, the authors first propose a novel supervised intrusion detection method based on TCM-KNN (Transductive Confidence Machines for K-Nearest Neighbors) data mining algorithm. Moreover, the authors introduce active learning method to select the most qualified data for training and thus assist TCM-KNN effectively in fulfilling the intrusion detection task. Experimental results demonstrate the proposed method has better results both in detection rate and false positives than the state-of-the-art intrusion detection methods. The method can also ensure good detection performance after optimizations by using instance selection and feature selection mechanisms. Therefore, it is more suitable for the real network applications than the traditional ones.",

Two Matrix-based Fast Calculation Algorithms (MFCAs) are proposed to estimate the network capacity in a network scenario in which there is no channel sharing among multiple sessions and traffic is sensitive to delay with an end-to-end delay constraint. The first algorithm MFCA-1 is used to estimate network capacity in a situation where all links have the same delay. It estimates the maximum number of \u03ba-hop sessions in a network based on the \u03ba-hop adjacency matrix of the network. The second algorithm MFCA-2 is used to estimate network capacity in a situation where different links may have different delays. It calculates the maximum number of sessions in a network with an end-to-end delay constraint based on the adjacency matrix and the link-delay matrix of the network. Numerical and simulation results show that both MFCA-1 and MFCA-2 can calculate network capacity much faster than the well-known Brute-Force Search Algorithm (BFSA) but with the same accuracy. \u00a9 2007 Science Press.",

Up to now, high false alarm rate, requirement of high quality data for modeling the normal patterns and the deterioration of detection rate because of some 'noisy' data in the training set still make it not perform as well as expected in practice. This paper presents a novel network anomaly detection method based on improved TCM-KNN (transductive confidence machines for K-nearest neighbors) machine learning algorithm, which can effectively detect anomalies using normal data for training. A series of experiments on well known KDD Cup 1999 dataset demonstrate that it has lower false positive rate, especially higher confidence under the condition of ensuring high detection rate than the traditional anomaly detection methods. In addition, even provided with training dataset contaminated by 'noisy' data, the proposed method still holds good detection performance. Furthermore, it can be optimized without obvious loss of detection performance by adopting small dataset for training and employing feature selection aiming at avoiding the 'curse of dimensionality'.",

The part which is larger than the threshold uses large-scale structure element to detect the edge, and uses small-scale structure element for the part less than the threshold. Large-scale structure element gets through small-scale structure element's dilation. The experimental results show that the proposed algorithm is more efficient than the usually used gradient-based edge detecting algorithms. \u00a9 2007 IEEE.",

This paper investigates a novel feature extraction approach to MRI segmentation based on Feed-back Pulse Coupled Neural Network in conjunction with toboggan theory. Due to the dynamics of the FPCNN, multiple unconnected groups of neurons will often pulse at the same time, calling for further processing to identify distinct regions. We locate the object's label by FPCNN. Finally, toboggan automatically partitions the MRI image.

Network anomaly detection has been an active and difficult research topic in the field of Intrusion Detection for many years. However, it still has some problems unresolved. They include high false alarm rate, difficulties in obtaining exactly clean data for the modeling of normal patterns and the deterioration of detection rate because of some \"noisy\" data in the training set. In this paper, we propose a novel network anomaly detection method based on improved TCM-KNN (Transductive Confidence Machines for K-Nearest Neighbors) machine learning algorithm. A series of experimental results on the well-known KDD Cup 1999 dataset demonstrate it can effectively detect anomalies with high true positive rate, low false positive rate and high confidence than the state-of-the-art anomaly detection methods. In addition, even interfered by \"noisy\" data (unclean data), the proposed method is robust and effective. Moreover, it still retains good detection performance after employing feature selection aiming at avoiding the \"curse of dimensionality\". Copyright 2007 ACM.",

        "abstract": "Network anomaly detection plays a vita role in securing network security and infrastructures. Current research focuses concentrate on how to effective reduce high false alarm rate and usually ignore the fact that the poor quality data for the modeling of normal patterns as well as the high computational cost make the current anomaly detection methods not act as well as we expect. Based on these, we first propose a novel data mining scheme for network anomaly detection in this paper. Moreover, we adopt data reduction mechanisms (including genetic algorithm (GA) based instance selection and filter based feature selection methods) to boost the detection performance, meanwhile reduce the computational cost of TCM-KNN. Experimental results on the well-known KDD Cup 1999 dataset demonstrate the proposed method can effectively detect anomalies with high detection rates, low false positives as well as with high confidence than the state-of-the-art anomaly detection methods. Furthermore, the data reduction mechanisms would greatly improve the performance of TCM-KNN and make it be a good candidate for anomaly detection in practice. \u00a92007 IEEE.",

        "abstract": "Because of changing temperature, silicon's wearing out, and the other unpredictable factors, besides testing on chips when leaving factory, in some applications, such like life-protected and aviation system, microchips need real-time and in-operation test even if they have been used in system. This paper focuses on a new in-operation self-testing mechanism. This mechanism is used to detect the silicon defects of cores of SoC chips in working state. It makes embedded cores to automatically check their failures by themselves based on IEEE std 1500TM and Core Test Language. According to Experiments, as a compromise, this In-operation Self-Test mechanism slows down the computation performance of SoC chips. Using this mechanism ensures finding exception in time and in turn adopting spare scheme in time, as well as it outperforms previous approaches in reducing cost of importing failure tolerance mechanisms into SoC chips. \u00a9 2007 IEEE.",

Our idea is that bad email server configuration, network attack, and spamware usually generate special or abnormal packets, which are often reflected by the characterization of email traffic. Therefore, we process these traffic data by selecting some indicating parameters on the basis of the EFSA model, and then investigate abnormal traffic by identifying abnormal values. We apply our mechanism to email traffic data captured at one of the largest commercial Internet Service Provider (ISP) in China. Our initial results are quite unexpected and interesting, which include uncommon command packet number distribution, unexpected event sequence combinations, and surprising protocol errors. In terms of the number of command packet, the number of abnormal email accounts for 10.5%. Based on event sequence analysis, we believe that the SMTP port scan happened at the time of data collection. \u00a9 2006 IEEE.",

        "abstract": "As network attacks have increased in number and severity over the past few years, intrusion detection is increasingly becoming a critical component of secure information systems and supervised network intrusion detection has been an active and difficult research topic in the field of intrusion detection for many years. However, it hasn't been widely applied in practice due to some inherent issues. The most important reason is the difficulties in obtaining adequate attack data for the supervised classifiers to model the attack patterns, and the data acquisition task is always time-consuming and greatly relies on the domain experts. In this paper, we propose a novel supervised network intrusion detection method based on TCM-KNN (Transductive Confidence Machines for K-Nearest Neighbors) machine learning algorithm and active learning based training data selection method. It can effectively detect anomalies with high detection rate, low false positives under the circumstance of using much fewer selected data as well as selected features for training in comparison with the traditional supervised intrusion detection methods. A series of experimental results on the well-known KDD Cup 1999 data set demonstrate that the proposed method is more robust and effective than the state-of-the-art intrusion detection methods, as well as can be further optimized as discussed in this paper for real applications. \u00a9 2007 Elsevier Ltd.

The main idea of image retrieval based on object region is to use the feature of object region instead of the feature of global image to participate in the image retrieval. In the field of graphics there is a technique called graph cut, which can be used to figure out the contour of object under the interaction of users. The graph cut algorithm can be used to verify the correctness of object region extraction, and the users' input about seeds can be simulated according to the initial object region extracted. The usage of graph cut can make the object region extracted more precisely and thus the performance of image retrieval based on object region can be improved. Experiments show that the object region extraction algorithm based on graph cut is valid and the subsequent image retrieval results accord with the human visual perception much more than the ones without the usage of graph cut.",

We now present a blind MUD based on improved subspace tracking algorithm that we believe can reduce considerably computational complexity while keeping satisfactory convergence speed and stability unchanged. In the full paper, we explain the blind MUD in some detail; in this abstract, we just add some pertinent remarks to listing the two topics of explanation. The first topic is: The modified model of minimum mean square error (MMSE) MUD. In this topic, we point out that the modified model reduces the errors caused by subspace estimation and improves the detection performance of the blind MUD. The second topic is: The improved subspace tracking algorithm based on power iteration. In this topic, we present the iteration process of the algorithm to obtain the main signal subspace, as given in eqs. (11) through (19) in the full paper. The algorithm with power iteration has global convergence while reducing computational complexity considerably. Finally we simulate our algorithm in comparison with the OPAST algorithm. The simulation results, shown in Figs. 1 and 2 in the full paper, demonstrate preliminarily that our algorithm converges much faster and its stability is better than the OPAST algorithm and that its MMSE is much lower than that of OPAST algorithm, while keeping the computational complexity unchanged. The simulation results thus verify the effectiveness of the blind MUD.",

        "abstract": "Archaea contain a variety of chromatin proteins consistent with the evolution of different genome packaging mechanisms. Among the two main kingdoms in the Archaea, Euryarchaeota synthesize histone homologs, whereas Crenarchaeota have not been shown to possess a chromatin protein conserved at the kingdom level. We report the identification of Cren7, a novel family of chromatin proteins highly conserved in the Crenarchaeota. A small, basic, methylated and abundant protein, Cren7 displays a higher affinity for double-stranded DNA than for single-stranded DNA, constrains negative DNA supercoils and is associated with genomic DNA in vivo. The solution structure and DNA-binding surface of Cren7 from the hyperthermophilic crenarchaeon Sulfolobus solfataricus were determined by NMR. The protein adopts an SH3-like fold. It interacts with duplex DNA through a \u03b2-sheet and a long flexible loop, presumably resulting in DNA distortions through intercalation of conserved hydrophobic residues into the DNA structure. These data suggest that the crenarchaeal kingdom in the Archaea shares a common strategy in chromatin organization. \u00a9 2007 The Author(s).",

Since two signs are introduced to indicate the beginning and ending of every segment of watermark information, the length of the character string assigned to every watermark pixel can be unequal. The method is robust against the channel error, thus causing loss of watermarked indices. Meanwhile, most pixel values are small for nonbinary watermark, so the total number of demanded image blocks and the extra distortion of the watermarked image can be decreased.

Six types of edge and six prototype vectors are defined, among them the latter are taken as inputs into SOM to classify the edge types and then obtain edge images from which the speckled edges are removed to acquire ideal edge images.

Isolating the task and executive object physically and logically is a effective way to eliminate the fraudulent behavior. Discussed in this paper is the problem of security policy on the executions of workflows. Workflows are intuitively specified with Petri nets. Petri net is a formal description tool, especially adapt to describe discrete event dynamic system. Furthermore, Petri net, a graphical description tool, can describe dynamic actions in a system by the way of token moving. Specially, the tasks in workflow systems and the relationship between the tasks and the roles are distinctly specified with Petri nets. The security rules are formally represented in Prolog. Based on the formal specification, the security rules are analyzed using logical reasoning to find all valid execution chains of a workflow. Through analysis, all valid execution chains are found, which satisfy the security rules.",

In this paper, based on multi-scale morphology algorithm is proposed to detect the edge of brain MRI with Gaussian and salt & pepper noise. Threshold is to classify the MRI into two opposite classes: object and background. The part which is larger than the threshold uses large-scale structure element to detect the edge, and uses small-scale structure element for the part less than the threshold. Large-scale structure element gets through small-scale structure element's dilation. The experimental results show that the proposed algorithm is more efficient for medical image denoising and edge detection than the usually used gradient-based edge detecting algorithms. \u00a9 2007 IEEE.",

The study of parameter optimization of damping control for poorly damped oscillations by combining genetic algorithm (GA) with damping assessment in a time-domain program simulation was carried out. The objective function for GA takes damping ratio as its variable. Test results for both 6-machine-dual-infeed HVDC and 50-machine-145- bus systems show that the algorithm extracts key information from multi-machine oscillations correctly; damping ratio is an effective index for evaluation of damping control effect; coordinated damping control based on information aforementioned provides good damping torque to oscillations after fault and improves system large-signal dynamic performance apparently.",

This approach firstly described the discontinuity by using morphological operations and redefines homogeneity, improved the image's anti-noise property. Then taking advantage of homogeneity histogram which was counted to gain the peaks and valleys by using peak-finding algorithm, the image into several small parts was divided. It lastly calculated the mean gray-scale value of different sub-region, combinations those areas which satisfied restrained conditions, and got the filtered image. The experimental results show that the proposed method effectively removes the noise of the image, and is better to reserve details of the image and the edge information compared with other methods. Moreover, the filtering effects are better than others for different noise density in the image.",

Most template detection methods utilize content repetition as a hint to detect template blocks that lots of web pages are required as input. So they usually process web pages in batches that a newly crawled page can not be processed until enough pages are collected. This consumes large storage consumption to cache web pages and results in a huge delay in data refreshing. In this paper, we present an incremental framework to detect templates in which a page is processed as soon as it has been crawled. Under this framework, we don't need to cache any web page. Experiments show that our framework consumes less than 7% storage than traditional methods. And also the delay of data refreshing induced by the batch process is completely eliminated. \u00a9 2008 IEEE.",

In TCP networks, the packet-dropping probability function is considered as a control input. Thus, a TCP/AQM controller is modeled as a time-varying delay system with a saturated input. The objective of the work described here is to design robust controller capable of achieving the desired queue size and guaranteeing asymptotic stability of the operating point. To achieve this aim, we have proposed an observer-based controller. For the particular TCP mode, applying the Lyapunov-Krasovsku function defined, the system can be stabilize with the obtained observer and the state feedback control law by using linear matrix inequality (LMI). Simulation results show that the derived control strategy is validated. \u00a92008 IEEE.",

After identifying transient portions, steady portions and quiet portions by Mel-frequency cepstral coefficient (MFCC) and energy, the proposed method uses time-scale modification to separate portions with different modification rates.

However, network anomalies especially Distributed Denial-of-Service (DDoS) attacks bombard web server, degrade its Quality of Service (QoS) and even deny the legitimate users' requests. Traditional network anomaly detection methods often lead to high false positives and expensive computational cost, thus unqualified for real-time web server anomaly detection. To solve these problems, in this paper we first propose an efficient network anomaly detection method based on Transductive Confidence Machines for K-Nearest Neighbors (TCM-KNN) algorithm. Secondly, we integrate a lot of objective and efficient anomalies impact metrics from the perceptions of the end users into TCM-KNN algorithm to build a robust web sever anomaly detection mechanism. Finally, Genetic Algorithm (GA) based instance selection method is introduced to boost the real-time detection performance of our method. We evaluate our method on a series of experiments both on well-known KDD Cup 1999 dataset and concrete dataset collected from real network traffic. The results demonstrate our methods are actually effective and lightweight for real-time web server anomaly detection. \u00a9 2008 Elsevier B.V. All rights reserved.",

        "abstract": "The aim of this study was to establish an animal model of experimental allergic encephalomyelitis (EAE) and examine the basic pathological changes, as well as expression and distribution of MMP-2 and MMP-9, in Wistar rats. Tissue sections were processed for HE staining, Weil myelin staining, and modified Bielschowsky staining. Expression and distribution of glial fibrillary acidic protein (GFAP), matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) were detected with immunohistochemistry. We divided the EAE into five types, depending on pathological characteristics and clinical manifestations: acute EAE, relapsing-remitting EAE, progressive EAE, benign EAE, and asymptomatic EAE. Rats with acute EAE suffered from quick, severe attacks with widespread inflammatory cells and axonal loss. No demyelination or astrocytic hyperplasia was found around the lesions. Rats with relapsing-remitting EAE broke down twice, with many perivascular cuffs and demyelinating plaques in lesions; hyperplastic and hypertrophic astrocytes characterized old lesions and axonal loss was evident. Rats suffering from progressive EAE exhibited continuous aggravation without improvement, accompanied by perivascular cuffs, demyelination, increased gliocytes and axonal damage. Rats with benign EAE recovered to a normal state with obviously decreased inflammatory cells and almost entirely unaffected myelin and axons. Rats with asymptomatic EAE also had various pathological changes that were not coincident with their clinical manifestations. Elevated expression of MMP-2 and MMP-9 was concordant in different types of EAE, but the extent differed in each type of EAE. MMP-2 and MMP-9 can be expressed in the form of vascular endothelial cells, meninges, or accumulated inflammatory cells. Multiple clinical courses of disease were demonstrated in Wistar rat EAE, with attributes similar to multiple sclerosis (MS) in clinical and pathological characteristics. Elevated expression of MMP-2 and MMP-9 may play a role in some aspects of pathological changes in EAE, for example, destroying the blood-brain barrier, degrading the myelin sheath, and damaging axons. \u00a9 The Authors 2008.",

Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) were employed to characterize the structure of the films. Transparency, water absorption percentage and contact angles were tested as well. Results showed that the transparency of gelatin-immobilized chitosan film could reach 98% or so, which could meet the requirement of optical transmittance in corneal regeneration. After the surface modification, water absorption percentage increased to 97.6%, while the contact angle declined to 73.4\u00b0, the hydrophilicity was improved and the biocompatibility could be enhanced. Results of culturing human fibroblasts on the gelatin-immobilized chitosan film showed that cells could adhere and proliferate well on the film, it exhibited good cell affinity. The gelatin-immobilized chitosan film was compatible with human fibroblasts which indicated that the gelatin-immobilized chitosan film could be a potential biomaterial for corneal regeneration.",

The main contribution of our method is that it allows for largely mismatched content between the adjacent views. To do this, we detect robust keypoints in each of the input images and match them between the adjacent views. Then the correct correspondences are employed to compute the projective matrix through least-square method. After aligning the inputs on the same plane, we use a weight mask to blend the overlapped views with different priorities. This blending strategy keeps the main information of the scene and avoids the interference of the mismatched inputs. We demonstrate the effectiveness of our method on image sets with large misregistration. \u00a9 2008 IEEE.",

        "abstract": "Based on constructing different types of distributed generations and energy storage equipments, this paper simulated the dynamical characteristics of MicroGrid with several operating modes under peer to peer control strategy. Two cases were used to analyze the role of storage equipment in MicroGrid. If micro turbine generation with traditional synchronization generator was used in MicroGrid as the main power adjustment unit, the frequency and voltage of MicroGrid would fluctuate during MicroGrid changed from grid-connected mode to islanded mode. In case 2, where the battery was installed in MicroGrid, the oscillation of frequency and voltage could be damped efficiently, and the operating mode switch time was shorten.",

In the first stage, we detect robust features in the initial frame of each webcam and find the corresponding points between them. Then the matched point pairs are employed to compute the perspective matrix which describes the geometric relationship of the adjacent views. After the initialization stage, we register the frame sequences of different webcams on the same plane using the perspective matrix and synthesize the overlapped region using a nonlinear blending method in real time. In this way, the narrow fields of each webcam are displayed together as one wide scene. We demonstrate the effectiveness of our method on a prototype that consists of two ordinary webcams and show that this is an interesting and inexpensive way to experience the wide-angle observation. \u00a9 2008 Springer Berlin Heidelberg.",

When micro-turbine-based synchronous generators are used as the main power support, the frequency of MicroGrid fluctuates greatly, and some DGs are disconnected from the grid by the low frequency relays, which is not beneficial to stable operation of the MicroGrid. After increasing storage devices, the storage devices play an important role in MicroGrid control, and the inverter of battery using droop control could provide fast power support for the islanded MicroGrid, and can damp the voltage and frequency fluctuations caused by the slow dynamical response of gas turbine efficiently.

The structure of films was characterized by Fourier transformed infrared spectroscopy with attenuated total reflectance (ATR-FTIR), x-ray photoelectron spectroscopy (XPS) and zeta potential. Results confirmed that hyaluronic acid was successfully immobilized on chitosan film. Transparency, water absorption percentage and contact angle of films were characterized. Results showed that there was no significant variation in transparency (p < 0.05) before and after immobilization, the maximum was up to 99% which was enough for corneal regeneration in clinical applications. After the immobilization, the time-dependent contact angle declined sharply (from 91.8\u00b0 to 67.7\u00b0 at 100 s). The hydrophilicity was significantly improved. The methylthiazol tetrazolium (MTT) (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay was used to assess cell viability and proliferation. Results showed that human cornea epithelial cells (HCEC) grew better on hyaluronic acid immobilized chitosan films than on chitosan films. The hyaluronic acid immobilized chitosan film could be a promising candidate material for corneal regeneration. \u00a9 2009 IOP Publishing Ltd.",

Sso pol B1 showed replication fidelity similar to or higher than most viral, bacterial, and eukaryotic replicases. The fidelity of the enzyme was about three times as high at 70\u00b0C as at 55\u00b0C. Approximately two-thirds of the errors made by the enzyme were single-base substitutions, of which 58% were C \u2192 T transition. Frameshift mutations, mostly resulting from single-base deletions, accounted for 19% of the total errors. An exonuclease-deficient mutant of Sso pol B1 was three times as mutagenic as the wild-type enzyme, suggesting that the intrinsic proofreading function contributed only modestly to the fidelity of the enzyme. Kinetic assays showed that the frequencies of all possible misincorporations by an exonuclease-deficient triple-point mutant of Sso pol B1 ranged from 5. 4 \u00d7 10",

        "abstract": "It was very important to analyze e-commerce protocols by formal methods. A technique for modeling the fair-change e-commerce protocol (FEEP) with automated dispute resolution and for verifying its property was proposed. First, FEEP was modeled in applied pi-calculus and a novel formalization of the fairness was provided in term of a correspondence property. Then, ProVerif, proposed by Juels, Catalano and Jakobsson, was adopted to analyze FEEP automatically. The results show that: it is feasible to formalize the fairness based on a correspondence property; ProVerif can be used to verify the property that before event A happened, event B had happened, but it is not applicable to analyze the property that after event A happened, event B would happen.",

Among them, the masking is an efficient method. SMS4 cipher was proved to be vulnerable to first-order DPA attacks, but there has been no countermeasure for it until now. In this paper, we focus on the security of SMS4 implementation, and present a secure implementation of SMS4 cipher with multiplicative masking. Moreover, composite field arithmetic, sharing and reusing hardware resources, and changing calculating orders are employed to produce a small SMS4 circuit.

Firstly, the system structure, controller, dual mode operating schemes and the influence on the traditional system protection are compared. The dynamical characteristics are compared via simulating different 10 kV line faults. The results indicate that type II micro turbine contributes larger short circuit currents, which has worse influence on the upper level protection scheme and equipment specifications. Furthermore, type II turbine needs more rigid mode changeover conditions. Type I turbine cannot change over seamlessly, but has less influences by other 11 kV line faults when connected, and contributes less short circuit currents.

Effects of the grinding conditions, including wheel velocity, feed rate and depth of cut, on the temperature were investigated. It was found that the grinding temperature measured under different grinding conditions varied from 100C to 300C when the wheel velocity was smaller than 160 m/s. The temperature could rise to about 800C at the wheel velocity of 160 m/s. The enhanced resistance of the air barrier formed around the wheel periphery at the higher velocity to the coolant supply was mainly responsible for the temperature rise. When the grinding forces and temperatures are considered comprehensively, high wheel speed and large depth of cut are preferable for the wet HSDG of engineering ceramics under low workpiece feed rate.

This paper presents a new method that makes the resulting image quality much improved, by mending the resampling values used during the process of image compositing, nearly not affecting the efficiency of rendering. In this method, two adjacent slices are defined as front slice and back slice respectively, according to the direction of the viewing ray. A cost function is defined for describing the two adjacent slices ' effect to the slab between them. The values of the resampling points in the front slice and back slice are inputted to the cost function as its parameters, and the resulting value can reflect the information of the slab more effectively.

        "abstract": "In this paper, an algorithm named Quantum and Biogeography based Optimization(QBO) is proposed to investigate the possibility of optimization by evolving multiple Quantum Probability Models(QPMs) via evolutionary strategies inspired by the mathematics of biogeography. In QBO, each QPM modeling an area in decision space represents a habitat, the whole population of QPMs evolve as an ecosystem with multiple habitats interacting. The migration and immigration mechanisms originally presented in Biogeography Based Optimization (BBO) [1] is introduced into QBO to implement the efficient information sharing among QPMs, which enhance the evolution of probability models towards the better status that can generate more better solutions. Experimental results on classical 0/1 knapsack problems of various scale show that the mechanisms in BBO are feasible to evolve multiple QPMs, and QBO is efficient for hard optimization problem.

The dominant strains and bacteria consortium were screened for COD treatment potential using an aerobic COD concentration decrease test. Ten strains, TJ01-TJ10, were isolated, of which six strains TJ02, TJ03, TJ05, TJ06, TJ07, and TJ09 were found to have higher COD removal when the single bacteria were added, all more than 20%. The most effective combination was TJ06 + TJ09; the COD removal efficiency reached 45.57%. 16S rDNA gene sequence analysis revealed that TJ06 and TJ09 belonged to the genus Bacillus. The effects of the dominant bacteria consortium on the high-salinity landfill leachate varied with pH value and the volume fraction of leachate. The COD removal efficiencies maintained higher when the pH value was 6-8 and the volume fractions of leachate were less than 80%.

Three models of graphene monolayers with different carbon periodicities due to the lattice mismatch are proposed in the presence and the absence of the Ru(0001) substrate separately. Considering the strain induced by the lattice mismatch, we optimize the atomic structures and investigate the electronic properties of the graphene. Our calculation results show that the graphene layers turn into periodic corrugations and there exist strong chemical bonds in the interface between the graphene N \u00d7 N superlattice and the substrate. The strain does not induce significant changes in electronic structure. Furthermore, the results calculated in the local density approximation (LDA) are compared with those obtained in the generalized gradient approximation (GGA), showing that the LDA results are more reasonable than the GGA results when only two substrate layers are used in calculation. \u00a9 2009 Chin.

        "abstract": "In this paper, we present a new computational model for contour detection. The algorithm is inspired by the researches of neurophysiology, which have revealed that the response of a central stimulus in the receptive field is affected by its surrounding stimuli. The measure firstly simulates the response function of the visual cell by researching into the structure of the primary visual cortex. And then, a new neighboring effect term is proposed to characterize the interactions of surrounding cells. The term balances different effects of the surrounding stimuli based on considering the distance, position and orientation of the stimulus; moreover, normalized computational model reduces computational complexity effectively. Finally, two tests are implemented to verify the feasibility and the stability of the proposed detection model. The experimental results show that our measure is superior to other methods and effectively detects contours in a clutter background. Especially, the advantages are more prominent under the condition of complicated scene. \u00a9 2009 ISSN.",

Appropriate characteristics suitable for study can be retrieved from heel impression by scanning the bare footprint in human footprint recognition system. In this work, an improved live wire processing method has been proposed to extract the barefoot heel impression exactly. According to the characteristics of footprint image, a new cost function has been defined in the live wire method. In order to improve the efficiency and accuracy of the extraction, ant colony optimization (ACO) algorithm has been employed to replace the Dijkstra method to find the shortest path, and to obtain the effective edge. The least square method was used then for ellipse fitting to obtain the parameters. The experimental result shows that the improved live wire method is effective in extracting barefoot heel impression. \u00a9 2009 ISSN.",

        "abstract": "An index structure ACEI (advanced CEI) is proposed in this paper to optimize the storage of CEI (containment-encoded intervals)-based interval index structure for data stream processing which involves a lot of operations of the numerical range query. It is necessary to construct a main memory-based query index with a low storage cost and little search time. The CEI index structure has low storage utilization, although it supports for high-speed query. To solve this problem, index structure ACEI is proposed. Based on CEI, through structural adjustment and optimization of parameters, ACEI can maintain the high speed of query operation and reduce the space complexity from O(R+N\u00b7W/L+N\u00b7log(L)) to O(sqrt(R\u00b7N)+N\u00b7sqrt(W)). Experiments show that ACEI structure can greatly improve the storage utilization and can be used for interval index against a large endpoint range. \u00a9 by Institute of Software, the Chinese Academy of Sciences.

As the pattern set size grows larger and larger, classical multiple string matching algorithms suffer from great performance degradation because of the massive storage usage of string matching automata. The authors propose optimization strategies for the classical string matching algorithm SBOM to reduce its automata size and improve its cache locality, which results in a great promotion in searching speed. More specifically, the Factor Oracle of SBOM algorithm is first replaced with a suffix tree structure, and then the rarely accessed automata nodes are removed through the pruning method to reduce suffix tree to nearly linear space complexity, and finally the pruned suffix tree is represented with double-array trie structure to compress its memory space. Compared with SBOM, this algorithm can greatly reduce memory usage and improve searching speed. Experiments on random data sets show that the proposed algorithm uses memory less than 5% of SBOM and achieves 100% performance improvement over SBOM algorithm. The proposed algorithm is especially suitable for high-speed online pattern matching.",

        "abstract": "Background: MicroRNAs (miRNAs) are small, endogenously expressed non-coding RNAs that regulate mRNAs post-transcriptionally. Previous studies have explored miRNA evolutionary trend, but evolutionary history and pattern in the miRNA world are still not fully clear. In the paper, we intended to analyze miRNA haplotype distribution and evolutionary network by analyzing miRNA sequences of miR-17 and miR-124 families across animal species as special populations. Principal Findings: 31 haplotypes were detected in miR-17 family while only 9 haplotypes were defined in miR-124 family. The complex miR-17 family was mainly distributed in vertebrates, but miR-124 was shared by more animal species from Caenorhabditis to Homo and had a wide distribution spectrum. Some haplotypes of the two miRNA families appeared discontinuous distributions across animals. Compared with a simple phylogenetic network in miR-124 family, miR-17 family indicated a complex network with some median vectors that might be lost ancestral or potential miRNA haplotypes. By analyzing different miRNAs across 12 animal species, we found these small RNAs showed different haplotype diversities, haplotype distributions and phylogenetic networks. Conclusions: Different miRNAs had quite different haplotype distributions and evolutionary patterns. Discontinuous distributions of miRNAs and median vectors in phylogenetic networks implied more members in the miRNA world. miRNA may be an excellent phylogenetic marker to discover its evolutionary history and pattern across the animal kingdom. \u00a9 2009 Guo et al.",

Methods: The EAE model was established in wistar rats immunized with fresh guinea pig spinal cord homogenate(GPSCH) and complete Freund's adjuvant (CFA). Wistar rats were divided randomly into five groups: normal control group, EAE group, dexamethasone(DXM) group, low dose TP-5 treated group, high dose TP-5 treated group. The levels of IL-12 and IL-10 in serum of wistar rats were detected by sandwich-ELISA on day 7, 14 and 21 post immunization. Results: Morbidity and clinical score of low dose TP-5 treated group and DXM group were significantly lower than those of EAE group and hish dose TP-5 treated group(P < 0.01). Morbidity and clinical score of DXM group were significantly lower than those of low dose of TP-5 treated group(P < 0.01). The levels of IL-12 of EAE group, DXM group, low dose TP-5 treated group and high dose TP-5 treated group were significantly higher than of normal control group at each time point(P < 0.01). The levels of IL-12 of DXM group and low dose TP-5 treated group were significantly lower than that of EAE group(P < 0.01), meanwhile the levels of IL-10 of DXM group and low dose TP-5 treated group were significantly higher than that of the rest groups on day 14 and 21 post immunization(P < 0.01). Conclusion: TP-5 has protective effects on EAE, and its functional mechanism may be associated with down. regulation of IL-12 as well as up-regulation of IL-10, so as to reverse the imbalance of TH ",

The capacity problems maximize the sum rate of CUs subject to the interference constraint for PUs and total transmitted power constraint can be solved with high complexity. To simplify the problem, this paper presents two suboptimal pre-coding schemes that pre-cancel the co-channel interference to PUs as well as mitigate interference between cognitive users (CUs). Simulation results show that the two suboptimal algorithms are able to achieve high sum rate throughput with low complexity. \u00a92009 IEEE.",

An important issue that has not been well studied so far is the selection of normal training data for network anomaly detection algorithm, which is highly related to the detection performance and computational complexity. Based on our previous proposed TCM-KNN (Transductive Confidence Machines for K-Nearest Neighbors) anomaly detection method, which can detect anomalies with high detection rate and low false positive rate, we develop an instance selection mechanism for TCM-KNN based on EFCM (Extended Fuzzy C-Means) clustering algorithm in this paper, aiming at limiting the size of training dataset, thus reducing the computational cost of TCM-KNN and boosting its detection performance. We report the experimental results over real network traffic. The results demonstrate the instance selection method presented in this paper is effective for TCM-KNN and thus optimizing it as an effectively lightweight network anomaly detection scheme.",

Firstly, the operating modes of MT are introduced briefly. Then operating characters and influence on traditional system protection are analyzed while MTs are connecting to the grid. The different dual mode schemes are compared via simulating different 10 kV line fault cases. Simulation results indicated that type II MT connected with grid via synchronal generator supplied larger short-circuit current, as well as worse influence on superior protection and equipment-selecting than those of type I MT which is connected with grid by converter. Further more, although type II MT can realize seamless transition, type II MT needs more strict mode transform condition than type I does, such as needing to coordinate the protection settings of turbine and system, and a braking resistance box should be used when MT is changing operating mode from grid connected (GC) mode to stand alone (SA) mode. While being grid-connected, type II MT is prone to be effected by other 10 kV lines fault. Contrarily, although type I turbine can not transform seamlessly, it has little influence on superior system protection and switchgear-selecting, as well as supplying low short circuit current.",

It is more difficult for network systems such as NIDS and Web Servers, because they must preserve flow order. But traditional flow-based load balancing schemes of network parallel processing systems, such as LLF, cost much resource and introduce lots of communication overhead. With the rapid popularization of multi-core system, it is a good choice to apply NIDS in CMP architecture to achieve higher performance. Some companies have taken the first step. Their scheduling algorithm operates at a custom NIC based on FPGA technology. LLF algorithm can't be used in such environment because it needs much more memory than NIC owns. In this paper, we propose a scheduling scheme that re-maps the new arrival flows when the system is unbalanced. To make effective adjustments we design a new triggering policy based on waiting lengths and their difference. Compared with LLF, our algorithm costs about 5% memory to get the same performance.",

The limitation of word length of instruction set and the number of operands in a single instruction have become a potential performance bottleneck for traditional SIMD extension. In this paper, we use LEON-2 as the host platform and present a novel low-cost architecture with extended shadow-f registers. In each extended instruction, some shadow-f registers are introduced to provide a copy of results received in the write-back stage, which can efficiently reduce the time of data transfer between LEON-2 and the coprocessor. Analysis of our proposed architecture shows that only partial replication of the whole register file is needed to mitigate the bandwidth limitation. At the same time, the proposed vector arithmetic unit is proved to be highly compatible to the required calculation patterns in the integer version of MELP algorithm. The application of our approach implemented on Stratix II FPGA show a promising speedup (up to 3.85X to some dominant kernels) with only 16% area increment. \u00a9 2009 IEEE.",

Unleashing the full potential of the unlabeled instances for stream data mining is, however, a significant challenge, consider that even fully labeled data streams may suffer from the concept drifting, and inappropriate uses of the unlabeled samples may only make the problem even worse. To build prediction models, we first categorize the stream data into four different categories, each of which corresponds to the situation where concept drifting may or may not exist in the labeled and unlabeled data.

Finally, we can obtain an estimation of the separating matrix and output signals.

        "abstract": "Cren7, a newly found chromatin protein, is highly conserved in the Crenarchaeota. The protein shows higher affinity for double-stranded DNA than for single-stranded DNA, constrains negative DNA supercoils in vitro and is associated with genomic DNA in vivo. Here we report the crystal structures of the Cren7 protein from Sulfolobus solfataricus in complex with two DNA sequences. Cren7 binds in the minor groove of DNA and causes a single-step sharp kink in DNA (\u223c53\u00b0) through the intercalation of the hydrophobic side chain of Leu28. Loop \u03b23-\u03b24 of Cren7 undergoes a significant conformational change upon binding of the protein to DNA, suggesting its critical role in the stabilization of the protein-DNA complex. The roles of DNA-contacting amino acid residues in stabilizing the Cren7-DNA interaction were examined by mutational analysis. Structural comparison of Cren7-DNA complexes with Sac7d-DNA complexes reveals significant differences between the two proteins in DNA binding surface, suggesting that Cren7 and Sul7d serve distinct functions in chromosomal organization. \u00a9 2010 Blackwell Publishing Ltd.",

        "abstract": "Based on the tracking observations of radio ranges and VLBI delays of Chang'E-1 (CE-1) satellite during the controlled landing on the Moon on March 1, 2009, the landing trajectory and the coordinates of the landing point are determined by positioning analysis. It is shown that the landing epoch (the emission epoch of the last signal) of CE-1 satellite on the Moon was at UTC8h13m6.51s. The lunar longitude, latitude and surface height of the landing point in the lunar primary axes frame are respectively 52.2732\u00b0, 1.6440\u00b0 and -3.56 km (the reference lunar radius is 1738 km). The uncertainties are 0.0040\u00b0, 0.0168\u00b0 and 0.18 km. The corresponding uncertainty in the tangential direction of the lunar surface is 0.52 km and the three-dimensional (3D) positioning uncertainty is 0.55 km. It is accordingly deduced that even with the present technical specifications of the radio ranges and VLBI delays, the 1 km 3D positioning precision could be guaranteed for the lander in the second stage of China's Lunar Exploration Project. Concerning the trace determination of the rover on the lunar surface, because only telemetry signal will be emitted, VLBI would be the sole tracking technique from the Earth. The application of the constraint of geocentric distance is shown to be helpful to improving the positioning precision. It is worthy to pay close attention to the applications of the same beam VLBI technique, the lunar topographic model and the on-board observations of the lander and rover to the position/trace determination of the rover. \u00a9 Science in China Press and Springer Berlin Heidelberg 2010.",

Some divergence was observed between expression distributions based on sequence count of the most abundant isomiR and sum of all isomiR sequence counts, respectively. But the divergence showed less effect on expression patterns in miRNA gene cluster and family. Because of high sensitivity of sequencing technology and ambiguous distribution of common isomiRs among multicopy miRNA precursors and homologous genes, most gene clusters and families showed inconsistent expression levels. Inconsistent expression pattern implied expression diversification in vivo although they maybe showed close relationship during transcription and/or gene regulation. Some gene clusters and families generated mature miRNAs from the same arms and even with the same lengths, especially in gene family. The interesting expression and length distribution maybe implied strict regulation during pre-miRNA processing through cleavage of Dicer and Drosha. The study showed that the most abundant isomiR may be a better marker, and global expression analysis of miRNA gene cluster and family provide clues for analyzing relative expression levels and understanding the function relationship and mechanism for expression regulation of miRNAs in regulation network. \u00a9 2010 Elsevier Ltd.",

The coexpressed miRNA clusters are pivotal in coordinately regulating multiple processes, including embryonic development, cell cycles and cell differentiation. In the study, relative expression analysis of miRNA cluster was performed based on isomiRs from high throughput DNA sequencing data using SOLiD\u2122 system. Similar expression pattern of miRNA cluster was detected by analyzing the most abundant isomer and multiple isomiRs, respectively. According to all the multiple isomiRs, miRNA* species always had fewer sequence counts and indicated different expression patterns with their miRNAs. Although co-transcribed from a single promoter as a single polycistronic transcript, miRNAs in gene cluster showed distinct levels. Inconsistent expression levels also could be detected after normalization of sequence counts despite degree of divergence was largely reduced. The difference of expression pattern might result from miRNA half-life because of degradation degree and rate. Inconsistent expression levels of members in miRNA cluster maybe contribute to complex biological processes in particular developmental contexts at specific times. The expression patterns according to the most abundant isomiR and all the multiple isomiRs are consistent, and relative expression analysis based on sequence counts and isomiRs from high throughput sequencing data provides a feasible method to analyze different miRNAs. \u00a9 2010 IEEE.",

        "abstract": "Background During typical microRNA (miRNA) biogenesis, one strand of a ~22 nt RNA duplex is preferentially selected for entry into a silencing complex, whereas the other strand, known as the passenger strand or miRNA* strand, is degraded. Recently, some miRNA* sequences were reported as guide miRNAs with abundant expression. Here, we intended to discover evolutionary implication of the fate of miRNA* strand by analyzing miRNA/miRNA* sequences across vertebrates. Principal Findings Mature miRNAs based on gene families were well conserved especially for their seed sequences across vertebrates, while their passenger strands always showed various divergence patterns. The divergence mainly resulted from divergence of different animal species, homologous miRNA genes and multicopy miRNA hairpin precursors. Some miRNA* sequences were phylogenetically conserved in seed and anchor sequences similar to mature miRNAs, while others revealed high levels of nucleotide divergence despite some of their partners were highly conserved. Most of those miRNA precursors that could generate abundant miRNAs from both strands always were well conserved in sequences of miR-#-5p and miR-#-3p, especially for their seed sequences. Conclusions The final fate of miRNA* strand, either degraded as merely carrier strand or expressed abundantly as potential functional guide miRNA, may be destined across evolution. Well-conserved miRNA* strands, particularly conservation in seed sequences, maybe afford potential opportunities for contributing to regulation network. The study will broaden our understanding of potential functional miRNA* species. \u00a9 2010 Guo et al.",

        "abstract": "Mode S Second Surveillance Radar (SSR) is very important means for Air Traffic Control (ATC) now and future, all the responding data which the radar receives need parity processing. Bit and confidence declaration is an vital step before error detection and error correction. Based on the commonly used baseline multi-sample algorithm, different conditions are presented and analyzed, the conditions under which error happens are pointed out, and the algorithm in which two statistical variables are added to avoid false declaration. In addition, the moving average method is used to preprocess the sampled data, so as to reduce the influence of noise. The merits the baseline multi-sample technique owes are preserved, and the added computation is small. The declaration veracity is improved, and consequently makes error detection and error correction be facilitated successfully. \u00a9 2010 Science Press, Institute of Electronics, CAS and Springer-Verlag Berlin Heidelberg.",

Basing on the complex variable partial differential method, an accurate algorithm was developed for parameter sensitivity analyzing during model updating. An iterative pattern was established for model updating with static measured data. With considering modal character forces, modal dynamic finite element model was equivalent to a static model for updating. Formulations of error estimates are derived for the model updating algorithm stability analysis. The numerical examples show that the developed method could efficiently update multiple and/or nonlinear parameters. The finite element model of Runyang suspension bridge tower was updated with the proposed method. The identified parameters are more accurate, and the correlation between the updated model and actual structure is much higher.",

Chaotic systems with diverse structures are taken as the nodes of the complex dynamical network, the nonlinear terms of the systems are taken as coupling functions, and the relations among the nodes are built through weighted connections. The structure of the coupling functions between the connected nodes is obtained based on Lyapunov stability theory. A complex network with nodes of Lorenz system, Coullet system, R\u00f6ssler system and the New system is taken as an example for simulation study and the results show that generalized chaos synchronization exists in the whole weighted complex network with different nodes when the coupling strength among the nodes is given with any weight value. The method can be used in realizing generalized chaos synchronization of a weighted complex network with different nodes. Furthermore, both the weight value of the coupling strength among the nodes and the number of the nodes have no effect on the stability of synchronization in the whole complex network. \u00a9 2010 Chinese Physical Society and IOP Publishing Ltd.",

In the MAQC-II project, 36 independent teams analyzed six microarray data sets to generate predictive models for classifying a sample with respect to one of 13 endpoints indicative of lung or liver toxicity in rodents, or of breast cancer, multiple myeloma or neuroblastoma in humans. In total, >30,000 models were built using many combinations of analytical methods. The teams generated predictive models without knowing the biological meaning of some of the endpoints and, to mimic clinical reality, tested the models on data that had not been used for training. We found that model performance depended largely on the endpoint and team proficiency and that different approaches generated models of similar performance. The conclusions and recommendations from MAQC-II should be useful for regulatory agencies, study committees and independent investigators that evaluate methods for global gene expression analysis. \u00a9 2010 Nature America, Inc.

Compared with the geometrical generating algorithm for 2D random polyhedral aggregate, the algorithm for 2D or 3D random polyhedral aggregate is simpler.

During the past two decades, a great deal of efforts has been devoted to the structure of C-S-H at the nanoscale level, including both experiment investigation and molecular simulation. The smallest C-S-H unit has a layered crystal structure at atomic scale, with a lamella thickness in the nm range. And moreover, ordered stacks of up to several tens or even hundreds of nano-lamellae have been observed experimentally. The key features of structure and morphology is remarkably the ubiquitous presence of an orientational order. Now we focus on the physical understanding on such orientational ordered C-S-H structures at mesoscale. In respect that there exists a high nematic order in the stacking C-S-H of nano-lamellae, by introducing some physical parameters, such as the magnitude of nematic order of the nano-lamellae, we try to predict the mechanical properties of the crystalline in terms of its micro-structure. \u00a9 (2010) Trans Tech Publications.",

The method was based on a meshless boundary element method which results in an integral equation for explicitly evaluating field chloride quantities. Weighted residual method and Green's function were adopted to derive domain and boundary integral equations. A radial integration method coupling with radial basis function approximation technology was used to convert domain integral into equivalent boundary integral. With central finite difference method, an explicit time iteration scheme was established for solving transient diffusion equation. Two numerical examples for 2D diffusion problem were given to demonstrate the robustness of the proposed method. Numerical results show that the non-homogenous diffusion coefficient causes the chloride distribution non-uniform, and the diffusion process is nonlinear with respect to time. \u00a9 (2010) Trans Tech Publications.",

In the study, we developed an approach for comparing relative expression levels of different miRNAs based on suitable endogenous miRNA control and their locus in the genome, miRNA group (such as miRNA cluster and miRNA 5amily), and phylogenetic relationship between corresponding precursor sequences. According to the approach, we analyzed miR-17-92 cluster and miR-17 family in mouse NIH3T3 cells from high throughput sequencing data using SOLID\u2122 system. Expression analysis of miR-17-92 cluster and miR-17 (mir-17) family showed evident diversity although some miRNAs were transcribed as a single polycistronic transcript. Combining locus on chromosome and phylogenetic relationship between precursors, different expression levels of these miRNAs might imply complex regulatory networks with gene locus and provide evolutionary and functional implication in miRNA biogenesis, especially for comparing miRNA expression profiles under varying conditions or between mutants and wild type. Our studies show that expression comparison of miRNAs correlated with locus, miRNA group, and phylogenetic relationship, can reveal important insights into the biogenesis, evolution, and function of miRNAs. \u00a9 2010 IEEE.",

Micro damage variable is defined as a function of stress degree in material point. A nonlinear finite element method (FEM) is constructed to conduct coupling analysis of micro damage degree. To represent the cumulative effect of micro damage, macro damage is defined as a statistically homogeneous ergodic function of micro damage variable. Equivalent response method is used to verify the relationship between the micro damage and macro damage. Numerical results show that the coupling analysis technology with iterative process can reduce mesh sensitivity significantly, and structural responses under homogenous macro damage coincide well with those under heterogeneous micro damage. With transforming structural micro damage into equivalent macro damage, the developed multi-scale damage model can improve the computing efficiency of structural state assessment oriented finite element model.",

The result of color points is caused by the following three factors; the first is dyestuffs can not dissolve sufficiently; the second is alkali can not dissolve sufficiently; the last one is equipments can not clean completely. The difference in color of selvage has something to do with the temperature and humidity of cloth, dye hydrolysis, bad dye compatibility and the irregularity of the both ends of the cloth. The causes of stain-defects lie in these four following aspects: alkali-saline patches, water droplets on the cloth, packing film dressing lax and condensate infiltrates rolls. Inadequate pre-treatment and using sodium in the process of dyeing can lead to feel hard. Poor color fastness is related to soap making, seam mark has something to do with winding tension, fabric variety and seam. Measures: cold pad-batch dyeing should choose activated dyestuff which has strong alkali, same immediacy and compatibility. Dye tank volume should less than 50L, and the temperature of dyeing stuff is 25 - 30 \u00b0C. Finally, seam and the both ends of the cloth are regular, then, workers curl the cloth and wrap in plastic film, and tight the both ends of plastic film in the roller rolling.",

Methods: Studies which reported the correlation between clinical factors and appearances on DWI in patients with TIA were systematically reviewed, then a Meta-analysis was performed. Results: Thirty-two studies were met the inclusion criteria. As the result of the Meta-analysis, several clinical factors were associated with positive DWI including symptom duration \u226560 min (22 studies; OR: 2.44; 95%CI: 1.72-3.47; P<0.001), dyskinesia (18 studies; OR: 2.43; 95%CI: 1.97-2.99; P<0.001), aphasia (15 studies; OR: 2.29; 95%CI: 1.33-3.95; P=0.003), dysarthria (10 studies; OR: 1.85; 95%CI: 1.28-2.68; P=0.001), atrial fibrillation (16 studies; OR: 2.24; 95%CI: 1.64-3.06; P<0.001) and artery atherosclerosis (17 studies; OR: 1.84; 95%CI: 1.28-2.64; P=0.001).

        "abstract": "Traffic classification is important to many network applications, such as network monitoring. The classic way to identify flows, e.g., examining the port numbers in the packet headers, becomes ineffective. In this context, deep packet inspection technology, which does not only inspect the packet headers but also the packet payloads, plays a more important role in traffic classification. Meanwhile regular expressions are replacing strings to represent patterns because of their expressive power, simplicity and flexibility. However, regular expressions mathcing technique causes a high memory usage and processing cost, which result in low throughout. In this paper, we analyze the application-level protocol distribution of network traffic and conclude its characteristic. Furthermore, we design a fast and memory-efficient system of a two-layer architecture for traffic classification with the help of regular expressions in multi-core architecture, which is different from previous one-layer architecture. In order to reduce the memory usage of DFA, we use a compression algorithm called CSCA to perform regular expressions matching, which can reduce 95% memory usage of DFA. We also introduce some optimizations to accelerate the matching speed. We use real-world traffic and all L7-filter protocol patterns to make our experiments, and the results show that the system achieves at Gbps level throughout in 4-cores Servers. \u00a9 2010 IEEE.",

But recently, this technique is also adopted by cyber-criminals and Internet miscreants to evade identification and to frustrate law enforcement and anticrime efforts aimed at locating and shutting down the illegal service. Previous work on this topic focuses mostly on detecting and measuring existing fast-flux based service networks ignoring the most import property provided by them-high availability under countermeasures. This paper attacks the availability problem of fast-flux based service network under countermeasures. In this paper, counter-system is taken into account and a model of these networks under countermeasures is presented. Based on this model, two evaluating factors of availability are proposed. By using reliability theory and queuing theory, this paper also performs a study of typical fast-flux based networks and their availability. Results show that both employed strategies and users' network environment have significant impacts on the availability of fast-flux based service network. \u00a9 2010 IEEE.",

        "abstract": "We consider the problem of optimizing and executing multiple continuous filtering rules, where each filtering rule is a conjunction of filtering units and each filtering unit may occur in multiple filtering rules. We focus on the problem of ordering the filtering units adaptively to minimize the cost in a multimedia stream environment where filtering units are very expensive. Significant performance gains are achieved by sharing filtering units across filtering rules. Existing methods are based on a greedy method which orders the filtering units according to three factors of the filtering units, i,e., the selectivity, connectivity, and cost. Although all these methods reported good results, there is still one important problem that hasn't been addressed yet. The selectivity factor is set by prior-knowledge which cannot adjust to the multimedia stream where characteristics of stream and filtering units vary unpredictably over time. In this paper, we propose a hierarchal clustering ordering framework (HCOF), which executes a two-stage ordering strategy. In the first ordering stage, HCOF clusters all the filtering units according to their popularities and costs factors. In the second stage, for each cluster, all the filtering units are then ordered according to their selectivity. Experiments on both synthetic and real multimedia streams demonstrate that our HCOF method outperforms other existing filtering methods. \u00a9 2010 IEEE.",

        "abstract": "Organisms belonging to the Crenarchaeota lineage contain three proliferating cell nuclear antigen (PCNA) subunits, while those in the Euryarchaeota have only one, as for Eukarya. To study the mechanism of archaeal sliding clamps, we sought to generate knockouts for each pcna gene in Sulfolobus islandicus, a hyperthermophilic crenarchaeon, but failed with two conventional knockout methods. Then, a new knockout scheme, known as marker insertion and target gene deletion (MID), was developed, with which transformants were obtained for each pMID-pcna plasmid. We found that mutant cells persisted in transformant cultures during incubation of pMID-pcna3 and pMID-araS-pcna1 transformants under counter selection. Studying the propagation of mutant cells by semiquantitative PCR analysis of the deleted target gene allele (Dpcna1 or Dpcna3) revealed that mutant cells could no longer be propagated, demonstrating that these pcna genes are absolutely required for host cell viability. Because the only prerequisite for this assay is the generation of a MID transformant, this approach can be applied generally to any micro-organisms proficient in homologous recombination. \u00a9 2010 SGM.",

        "abstract": "Related data streams refer to data streams that can be joined together by matching their join attributes. Existing research on learning from related data streams is based on an assumption that all streams arrive at a central processing unit in a synchronous way, such that in an arbitrary sliding window, all tuples of the streams can be perfectly joined together. This assumption, however, does not hold when related data streams are generated or transferred at different speeds, and thus may arrive in the central processing unit in an asynchronous manner. In this paper, we argue that for asynchronous data streams, there exist a small portion of perfectly joined examples (i.e., complete examples) and a large portion of partially joined examples (i.e., incomplete examples). Accordingly, we present a new Learning from Complete and Fixed Examples (LCFE) framework that can fix incomplete examples to boost the learning. Experiments on both synthetic and real-world data streams demonstrate that LCFE is able to achieve a higher prediction accuracy for learning from related data streams than other simple solutions can offer. \u00a9 2010 IEEE.",

It is shown that surprise is an important cue for the direction of human attention to unexpected events. Aiming to the difficulty of the definition and description of abnormity in videos, we present the use of Bayesian surprise, introduced in computer vision, for detection of certain types of unusual events. Multiple local monitors which collect low-level statistics (velocity or direction) are placed over the image. With the monitors' observation and a set of reference measurement previously acquired, a pixel-wise surprise trigger is computed using Bayesian probabilistic inference techniques. Once the surprise value exceed by a preset threshold, the monitor outputs an alert. These alerts are integrated to a final decision regarding the existence of an unusual event. It was tested on a variety of real-life crowded scenes. The results show that the proposed method localized the regions of anomalies in the abnormal frames successfully, thus demonstrating the practical applicability of the scheme. \u00a9 2010 IEEE.",

        "title": "SKIF: A data imputation framework for concept drifting data streams",
        "abstract": "Missing data commonly occur in many applications. While many data imputation methods exist to handle the missing data problem for databases, when applied to concept drifting data streams, these methods share some common difficulties. First, due to large and continuous data volumes, we are unable to maintain all stream records to form a candidate pool for missing value estimation, as most existing methods commonly do. Second, even if we could maintain all complete stream records using a summary structure, the concept drifting problem would make some information obsolete, and thus deteriorate the imputation accuracy. Third, in data streams, it is necessary to develop a fast yet accurate algorithm to find most similar data for imputation. Fourth, due to dynamic and sophisticated data collection environments, the missing rate of most stream data may be much higher than that in databases, so the imputation method should be able to handle high missing rate in the data. To tackle these challenges, we propose a Streaming k-Nearest-Neighbors Imputation Framework (SKIF) for concept drifting data streams. To handle concept drifting and large volume problems in data streams, SKIF first summarizes historical complete records in some micro-resources (which are high-level statistical data structures), and maintains these micro-resources in a candidate pool as benchmark data. After that, SKIF employs a novel hybrid-kNN imputation procedure, which uses a hybrid similarity search mechanism, to find the most similar micro-resources from the large scale candidate pool efficiently. Experimental results demonstrate the effectiveness of the proposed SKIF framework for data stream imputation tasks. \u00a9 2010 ACM.",

Most image classification systems have taken one of two approaches, using either global or local features exclusively. This may be in part due to the difficulty of combining a single global feature vector with a set of local features in a suitable manner. To classify images for versatile applications, an effective algorithm is needed urgently. In this paper, we propose a new texture invariant descriptor to represent global features of an image, and propose a new method which combining local appearance feature with this texture descriptor in face image classification application. Results show the superior performance of these combined method over the hierarchical Bayesian classifier, with a reduction of over 2% in the error rate on a challenging two class dataset from Caltech dataset in face image classification. \u00a9 2010 IEEE.",

        "title": "Classifier and cluster ensembles for mining concept drifting data streams",
        "abstract": "Ensemble learning is a commonly used tool for building prediction models from data streams, due to its intrinsic merits of handling large volumes stream data. Despite of its extraordinary successes in stream data mining, existing ensemble models, in stream data environments, mainly fall into the ensemble classifiers category, without realizing that building classifiers requires labor intensive labeling process, and it is often the case that we may have a small number of labeled samples to train a few classifiers, but a large number of unlabeled samples are available to build clusters from data streams. Accordingly, in this paper, we propose a new ensemble model which combines both classifiers and clusters together for mining data streams. We argue that the main challenges of this new ensemble model include (1) clusters formulated from data streams only carry cluster IDs, with no genuine class label information, and (2) concept drifting underlying data streams makes it even harder to combine clusters and classifiers into one ensemble framework. To handle challenge (1), we present a label propagation method to infer each cluster's class label by making full use of both class label information from classifiers, and internal structure information from clusters. To handle challenge (2), we present a new weighting schema to weight all base models according to their consistencies with the up-to-date base model. As a result, all classifiers and clusters can be combined together, through a weighted average mechanism, for prediction. Experiments on real-world data streams demonstrate that our method outperforms simple classifier ensemble and cluster ensemble for stream data mining. \u00a9 2010 IEEE.",

Our essential goal is to build a robust prediction model from noisy stream data to accurately predict future samples. For noisy data sources, most existing works rely on data preprocessing techniques to cleanse noisy samples before the training of decision models. In data stream environments, these data preprocessing techniques are, unfortunately, hard to apply, mainly because the concept drifting in a data stream may make it very difficult to differentiate noise from samples of changing concepts. Accordingly, we propose an aggregate ensemble (AE) learning framework. The aim of AE is to build a robust ensemble model that can tolerate data errors. Theoretical and empirical studies on both synthetic and real-world data streams demonstrate that the proposed AE learning framework is capable of building accurate classification models from noisy data streams. \u00a9 2010 Elsevier B.V.

However, there are few published papers in literatures for various reasons. In this paper, based on the engineering technical requirements and the corresponding cutter head's structure design requirements, a nonlinear multi-objective disc cutters' layout mathematical model with complex constraints and the corresponding multi-stage solution strategy are presented, in which the whole disc cutters' layout design process is decomposed into the disc cutters' spacing design and the disc cutters' plane layout design. A numerical simulation method based on the FEM theory is adopted to simulate the rock chipping process induced by three TBM disc cutters to determine the optimal cutter spacing. And a cooperative coevolutionary genetic algorithm (CCGA) is adopted to solve the disc cutters' plane layout design problem. Finally, a disc cutters' layout design instance of the TBM is presented to demonstrate the feasibility and effectiveness of the proposed method. The computational results show that the proposed method can be used to solve the disc cutters' layout design problem of the TBM and provide various layout schemes within short running times for the engineers to choose from. \u00a9 2011 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.",

Deterministic Finite Automaton (DFA), which recognizes a set of regular expressions, is usually adopted to cater to the need for real-time processing of network traffic. However, the huge memory usage of DFA prevents it from being applied even on a medium-sized pattern set. In this article, we propose a matrix decomposition method for DFA table compression. The basic idea of the method is to decompose a DFA table into the sum of a row vector, a column vector and a sparse matrix, all of which cost very little space. Experiments on typical rule sets show that the proposed method significantly reduces the memory usage and still runs at fast searching speed. \u00a9 2011 Springer-Verlag Berlin Heidelberg.",

        "abstract": "Ramsey's theorem is a foundational result in combinatorics, which adopts many technologies in each embranchment of mathematics. Its conclusions are very important in set theory, logic, analysis, algebra and so on. But the Ramsey number problem is one of the most difficult problems in mathematics, and there are only 9 Ramsey numbers that have been solved. The objective of this paper is to solve the Ramsey number problem. We propose an improved DNA computing model based on the biological operations in the Adleman-Lipton model, the solution space of stickers in the sticker-based model, and the add-bit-sequence coding method proposed by Xu Jin, et al. According to the proposed algorithm, we can obtain lower bound and upper bound by means of specific mathematical formulas which already exist firstly. For each number from lower bound to upper bound, we build the initial answer space. Then, we remove the DNA chains which accord with special qualifications. Finally, we detect the final test tube to confirm whether the current number is a Ramsey number or not. The theoretic analysis and simulated experiments show that the solution to the difficult Ramsey number problem is possible in acceptable time, provided that the technology of DNA biology is mature enough in the future.",

The proposed architecture is easy to extend and area-economical. Furthermore, towards the system bottlenecks, systolic cell and data memory organization, optimized structure are presented. Compared with the traditional architecture, the proposed architecture can achieve the improvements of speed and area at the same time.

        "abstract": "The genomes of two Sulfolobus islandicus strains obtained from Icelandic solfataras were sequenced and analyzed. Strain REY15A is a host for a versatile genetic toolbox. It exhibits a genome of minimal size, is stable genetically, and is easy to grow and manipulate. Strain HVE10/4 shows a broad host range for exceptional crenarchaeal viruses and conjugative plasmids and was selected for studying their life cycles and host interactions. The genomes of strains REY15A and HVE10/4 are 2.5 and 2.7 Mb, respectively, and each genome carries a variable region of 0.5 to 0.7 Mb where major differences in gene content and gene order occur. These include gene clusters involved in specific metabolic pathways, multiple copies of VapBC antitoxin-toxin gene pairs, and in strain HVE10/4, a 50-kb region rich in glycosyl transferase genes. The variable region also contains most of the insertion sequence (IS) elements and high proportions of the orphan orfB elements and SMN1 miniature inverted-repeat transposable elements (MITEs), as well as the clustered regular interspaced short palindromic repeat (CRISPR)-based immune systems, which are complex and diverse in both strains, consistent with them having been mobilized both intra- and intercellularly. In contrast, the remainder of the genomes are highly conserved in their protein and RNA gene syntenies, closely resembling those of other S. islandicus and Sulfolobus solfataricus strains, and they exhibit only minor remnants of a few genetic elements, mainly conjugative plasmids, which have integrated at a few tRNA genes lacking introns. This provides a possible rationale for the presence of the introns. Copyright \u00a9 2011, American Society for Microbiology. All Rights Reserved.",

Using complex variable differential method, an efficient parameter sensitivity analysis technology was developed. Statistic formula also was constructed to calculate the errors in model updating process. The numerical examples verified that the developed method is efficient and reliable for model updating. As a case study, the model of the Run Yang Bei-Cha Yangzi cable stayed bridge tower was updated with the pseudo static model updating method.

In the first case, how to choose one fixed cognitive user and power control for each transmission antenna at the cognitive base station are considered to maximize the cognitive link's stable throughput. In the second case, a scheme to choose a group of cognitive users and a Zero-Forcing method to pre-white co-channel interference to the primary user, are also proposed in order to maximize cognitive base station's sum-rate.

        "abstract": "High-throughput sequencing is a powerful tool for discovering and profiling microRNAs (miRNAs) to gain further insights into their biogenesis and function. Due to shorter size, short RNAs from deep sequencing dataset are prone to map to multiple loci with an equal number of mismatches, especially among multicopy miRNA precursors and homologous miRNA genes. Systematic analysis of SOLiD sequencing dataset showed that 37.94% short RNAs could simultaneously map to more than one miRNA precursor, and more short RNAs were found to have multiple genomic loci. Improper selection from candidate loci might lose some mapping information, influence miRNA expression profile or even mislead to identify novel miRNAs. A comprehensive study indicated several potential features for correction strategy: location and distribution of mismatches, quality values, expression profiles of multiple isomiRs (miRNA variants), miRNA* and moRs (miRNA-offset-RNAs) at candidate locus and in its flank sequence. Further studies should develop an approach to correct the widespread phenomenon of multiple mapping based on these features, and improve accuracy of profiling and discovering miRNAs. \u00a9 2011 Elsevier Ireland Ltd.",

The performance of the proposed steganalysis is evaluated against 4 steganographic schemes: Direct Sequence Spread Spectrum (DSSS), Quantization Index Modulation (QIM), ECHO embedding (ECHO), and Least Significant Bit embedding (LSB). Experiment results show that the classifying performance of the proposed detector is much superior to the previous work. Even more exciting is that the proposed methodology could detect the four steganography, with 85%+ classification accuracy achieved in all the detections, which makes the proposed steganalysis methodology capable of being regarded as a blind steganalysis, and especially useful when the steganalyzer are without the knowledge of the steganographic scheme employed in data embedding. \u00a9 2011 Science Press, Institute of Electronics, CAS and Springer-Verlag Berlin Heidelberg.",

        "abstract": "Deep packet inspection sometimes is called application level semantic detection, which is capable of examining the content of data packets in order to provide application-specific services and improve network security. Application traffic classification based on regular expressions is an essential step for deep packet inspection. However regular expression, especially multiple regular expression matching is known to require intensive system resources and is often a performance bottleneck. Currently, the DFAs of regular expression are constructed in the preprocessing stage and the context of network streams is excluded which leads to low throughputs. In this paper, we analyzed the application level protocols and found that the protocols are asymmetrically distributed and it is changing dynamically. From the protocol distribution characteristic, we proposed an adaptive multiple regular expression matching method for application traffic classification with deep packet inspection. The adaptive method, schedule the multiple DFAs through splay tree by matching probability other than linear scheduling in linked list, can adjust scheduling sequence according with the changing dynamic traffics. We evaluate the proposed method with the L7 rules; experiments proved that our method can improve the throughputs more than three times. \u00a9 2011 ACADEMY PUBLISHER.",

        "abstract": "MicroRNAs (miRNAs) have important roles in various biological processes. miRNA cross-mapping is a prevalent phenomenon where miRNA sequence originating from one genomic region is mapped to another location. To have a better understanding of this phenomenon in the human genome, we performed a detailed analysis in this paper using public miRNA high-throughput sequencing data and all known human miRNAs. We observed widespread cross-mapping events between miRNA precursors (pre-miRNAs), other non-coding RNAs (ncRNAs) and the opposite strands of pre-miRNAs by analyzing the high-throughput sequencing data. Computational analysis on all known human miRNAs also confirmed that many of them could be involved in cross-mapping events. The processing or decay of both ncRNAs and pre-miRNA opposite strand transcripts may contribute to miRNA enrichment, although some might be miRNA-mimics due to miRNA mis-annotation. Comparing to canonical miRNAs, miRNAs involved in cross-mapping events between pre-miRNAs and other ncRNAs normally had shorter lengths (17-19 nt), lower prediction scores and were classified as pseudo miRNA precursors. Notably, 4.9% of all human miRNAs could be accurately mapped to the opposite strands of pre-miRNAs, which showed that both strands of the same genomic region had the potential to produce mature miRNAs and simultaneously implied some potential miRNA precursors. We proposed that the cross-mapping events are more complex than we previously thought. Sequence similarity between other ncRNAs and pre-miRNAs and the specific stem-loop structures of pre-miRNAs may provide evolutionary implications. \u00a9 2011 Guo et al.",

        "abstract": "Application-level protocol specifications (i.e., how a protocol should behave) are helpful for network security management, including intrusion detection and intrusion prevention. The knowledge of protocol specifications is also an effective way of detecting malicious code. However, current methods for obtaining unknown protocol specifications highly rely on manual operations, such as reverse engineering which is a major instrument for extracting application-level specifications but is time-consuming and laborious. Several works have focus their attentions on extracting protocol messages from real-world trace automatically, and leave protocol state machine unsolved. In this paper, we propose Veritas, a system that can automatically infer protocol state machine from real-world network traces. The main feature of Veritas is that it has no prior knowledge of protocol specifications, and our technique is based on the statistical analysis on the protocol formats. We also formally define a new model - probabilistic protocol state machine (P-PSM), which is a probabilistic generalization of protocol state machine. In our experiments, we evaluate a text-based protocol and two binary-based protocols to test the performance of Veritas. Our results show that the protocol state machines that Veritas infers can accurately represent 92% of the protocol flows on average. Our system is general and suitable for both text-based and binary-based protocols. Veritas can also be employed as an auxiliary tool for analyzing unknown behaviors in real-world applications. \u00a9 2011 Springer-Verlag Berlin Heidelberg.",

In this paper we focus on how to improve matching performance. We believe that performance can be improved by exploiting some characteristics of network traffic: magic first symbol and zipf-like distribution of application traffic. To the best of our knowledge, we are the first to observe and utilize them in traffic classification. In this paper, we analysis the expected matching times per flow before it is classified. Then, we introduce an enhanced traffic classification engine with the help of above characteristics and some optimizations, which has the same matching accuracy with the original L7-filter engine. We evaluate the enhanced engine, the result shows that it can improve matching performance with one order of magnitude, at the cost of a negligible increase in memory consumption. Furthermore, it does not depend on network environments and not require any training phase. \u00a9 2011 ACM.",

        "abstract": "Background: To gain insight into potential roles of isomiR spectrum and isomiRs with 3\u2032 additions in pre-eclampsia, we performed a comprehensive survey of miRNA repertoire and 3\u2032 addition events from placental samples with different degrees of pre-eclampsia by applying SOLiD sequencing platform. Principal Findings: Over 30% isomiRs were detected with 3\u2032 non-template additional nucleotides, especially for additional nucleotide of adenosine. However, these modified isomiRs showed a lower percentage of total miRNA expression (<15%). Generally, 1-3 abundant isomiRs from a given miRNA locus were identified, but none of them was detected with 3\u2032 additions. Different miRNAs indicated various isomiR spectrums and expression patterns. The most abundant isomiR spectrum, isomiR profile and expression pattern always were stability, but herein we found several exceptions across samples, especially between normal and diseased samples. At isomiR level, we detected a distinct subset of differentially expressed modified isomiRs between normal and diseased samples or between mild and severe samples. Gene Ontology analysis of their experimentally validated target genes revealed enrichment for specific biological process categories. Conclusions: The phenomenon of multiple isomiRs, especially for isomiRs with 3\u2032 additions, is not a random event during pre-miRNA processing. Varieties of isomiRs and expression patterns reveal potential functional implication and should be taken into account. The study enriches association of miRNAs and human disease, including potential roles of various miRNA variants and 3\u2032 addition events. \u00a9 2011 Guo et al.",

In order to interrogate the in vivo role of archaeal topo III, we constructed and characterized a topo III gene deletion mutant of Sulfolobus islandicus. The mutant was viable but grew more slowly than the wild-type strain, especially in a nutrient-poor medium. Flow cytometry analysis revealed changes of the mutant in growth cycle characteristics including an increase in proportion of cells containing either more than two genome equivalents or less than one genome equivalent in exponentially-growing cultures. As shown by fluorescence microscopy, a fraction of mutant cells in the cultures were drastically enlarged, and at least some of the enlarged cells were apparently capable of resuming cell division. The mutant also shows a different transcriptional profile from that of the wild-type strain. Our results suggest that the enzyme may serve roles in chromosomal segregation and control of the level of supercoiling in the cell. \u00a9 2011.",

        "abstract": "Xunlei is a P2P file sharing application that is popular in China. The performance of previous P2P applications is limited by the selfishness of peers and the widely use of firewall. Xunlei applies implicit uploading strategy and firewall bypassing technologies to conquer above drawbacks. To evaluate the effects of above solutions, we perform a series of measurements on Xunlei and BitTorrent networks. Our study provides three new findings by comparing the situation in the two networks. (1)Com-pared with the free control strategy in BitTorrent, the implicit uploading strategy improves not only the number of active peers but also the seed ratio. Benefit from the strategy, Xunlei has much better downloading performance in our measurement. (2)The strategy extends the seed service time that is related to swarm lifespan. According to our result, Xunlei swarm lives longer than BitTorrent one. (3)The connectivity influences the performance greatly. The result of our measurement shows that only 5% peers can be connected directly. Our theoretical analysis and measurement results show that better connectivity also leads to higher downloading speed and longer lifespan. \u00a9 2011 IEEE.",

It is the key problem of many important scopes such as network information security, information retrieval and filtration, computational biology, etc. A great number of security problems have arisen with the wide application of pattern matching, especially in network information security systems, such as intrusion detection and prevention systems, anti-virus systems, anti-spam systems, firewall, etc. A method of algorithmic complexity attacks against WuManber which is a classical multi-patterrn algorithm, and the optimal solution of creating the attacking data are presented in this article. Compared with random data and the data from network, the attacking data can greatly reduce the searching speed of WuManber. Experiments on random data sets show that the larger character set, the better attacking performance. And experiments on the data from the network show that the attacking data can reduce WuManber searching speed by more than 50%. It is found that if a small part of the pattern set is known, the attack data can be created. Defensively speaking, it is important that the pattern set must be kept secret. This article also provides some strategies of improving the security of network information security systems. The attacking data can also be used in checking the system security.",

Recognizing large numbers of strings with U-, V-, and U-V-uncertain-strings, including the interleaving of two or more uncertain strings, is important to thoroughly gathering useful information and detecting harmful information. This paper proposes a complete automaton and its high-speed construction algorithm for large-scale U-, V-, and U-V-uncertain multiple strings, including two or more uncertain strings interlaced with one another. The maximum number of parallel complete automation of the V-uncertain string is also given. This paper reveals that there are two kinds of pretermissions, i. e., similarly-connected and interlaced-string pretermissions, and that mistake may appear in the matching of the regular expressions, or states in the automaton may increase in number, if the intersection of the U-uncertain strings sets and the homologous subsequent special point in the U-uncertain strings sets are not eliminated from the whole system. \u00a9 2011 Science China Press and Springer-Verlag Berlin Heidelberg.",

        "abstract": "Deep packet inspection plays a increasingly important role in network security devices and applications, which use more regular expressions to depict patterns. DFA engine is usually used as a classical representation for regular expressions to perform pattern matching, because it only need O(1) time to process one input character. However, DFAs of regular expression sets require large amount of memory, which limits the practical application of regular expressions in high-speed networks. Some compression algorithms have been proposed to address this issue in recent literatures. In this paper, we reconsider this problem from a new perspective, namely observing the characteristic of transition distribution inside each state, which is different from previous algorithms that observe transition characteristic among states. Furthermore, we introduce a new compression algorithm which can reduce 95% memory usage of DFA stably without significant impact on matching speed. Moreover, our work is orthogonal to previous compression algorithms, such as D2FA, \u03b4FA. Our experiment results show that applying our work to them will have several times memory reduction, and matching speed of up to dozens of times comparing with original \u03b4FA in software implementation. \u00a9 2011 IEEE.",

        "abstract": "Regular expression matching is widely used in many network applications to analyze suspicious traffic against predefined signatures, and to discover anomalous events. Deterministic Finite Automaton (DFA), which recognizes a set of regular expressions, is the basic data structure to scan input traffic byte by byte. Though DFA meets the requirement of real-time processing of network traffic, constructing a combined DFA for a set of regular expression signatures is very time-consuming, especially when the signature set is large. To attack this problem, we propose new strategies to accelerate DFA construction. The basic idea of our method is to construct the combined DFA by hierarchical merging of the DFAs of each single regular expression. Our method runs in O(\u0399Q\u0399\u0399\u2211\u0399 ln n) time, which is substantially superior to the time complexity O(\u0399Q\u0399\u0399\u2211\u0399(\u2211",

        "abstract": "Ensemble learning has become a common tool for data stream classification, being able to handle large volumes of stream data and concept drifting. Previous studies focus on building accurate prediction models from stream data. However, a linear scan of a large number of base classifiers in the ensemble during prediction incurs significant costs in response time, preventing ensemble learning from being practical for many real world time-critical data stream applications, such as Web traffic stream monitoring, spam detection, and intrusion detection. In these applications, data streams usually arrive at a speed of GB/second, and it is necessary to classify each stream record in a timely manner. To address this problem, we propose a novel Ensemble-tree (E-tree for short) indexing structure to organize all base classifiers in an ensemble for fast prediction. On one hand, E-trees treat ensembles as spatial databases and employ an R-tree like height-balanced structure to reduce the expected prediction time from linear to sub-linear complexity. On the other hand, E-trees can automatically update themselves by continuously integrating new classifiers and discarding outdated ones, well adapting to new trends and patterns underneath data streams. Experiments on both synthetic and real-world data streams demonstrate the performance of our approach. Copyright 2011 ACM.",

Prior works on traffic classification mainly focus their attentions on dividing Internet traffic into different categories based on application layer protocols (such as HTTP, BitTorrent etc.). Making traffic classification from another point of view, we divide Internet traffic into different content types. Our technology is an attempt to solve the classification problem of network traffic, which contains unknown and proprietary protocols (i.e., no publicly available protocol specification). In this paper, we design a classifier which can distinguish Internet traffic into different content types using machine learning techniques. Features of our classifier are entropy of consecutive bytes and frequencies of characters. Our method is capable of classifying real-world traces into different content types (including Text, Picture, Audio, Video, Compressed, Base64-encoded image, Base64-encoded text and Encrypted). The chief features of our classifier are small computing space (about 1K Bytes) and high classification accuracy (about 81%). \u00a9 2011 IEEE.",

We investigated that whether the key serum miRNAs could discriminate patients with and without breast cancer. This study was divided into three parts: (1) miRNA marker discovery using SOLiD sequencing-based miRNA profiling on cancerous and adjacent noncancerous breast tissue of one breast cancer patient; (2) marker selection and validation by real-time PCR on a small set of serum; (3) gene ontology analysis of the key miRNA target genes. Of genome-wide tissue miRNA expression analysis, five miRNAs were found to be altered more than fivefold by SOLiD sequencing (i.e., miR-29a, miR-23a, miR-23b, miR-192, and miR-21). All the five miRNAs were validated on the 20 breast cancer patients and 20 controls. miR-29a and miR-21 were significantly increased in the serum of breast cancer patients (P<.05). Gene ontology analysis of the target genes revealed enrichment for special biological process categories, that is, signal transduction, development, apoptosis, cell proliferation, and cell adhesion. SOLiD sequencing provides a promising method for cancer-related miRNA profiling. Serum miRNAs may be useful biomarkers for breast cancer detection. Copyright \u00a9 2011 Qian Wu et al.",

        "abstract": "Although peer-to-peer system is scalable for content distribution, its lifespan is shorter than traditional systems. More and more researchers began to pay close attention to lifespan and proposed specialized methods to extend it. However, what factors influence lifespan and how the effects are? To answer these questions, we analyze the long-term characteristics of swarms by our sampling measurement. The results show that swarms have different behaviors comparing with previous studies that focused on flash-crowd. Based on these new findings, we propose a long-term model to depict the swarm evolution in large time scale. According to our model, the attenuation parameter of arrive rate and the average task length influence lifespan linearly while the initial arrival rate and peer availability have logarithmic influence. In order to validate our model, we compare them with real swarm and simulations. Our experiments show that the model captures the evolution closely and our results are valid in different situations. \u00a9 2011 IEEE.",

More and more researchers pay close attention to swarm lifespan and propose specialized methods to extend it. Bundling technique and SRE (Share Ratio Enforcement) mechanism in Private Tracker system are two successful enhancements which are proved by practical systems. However, they have side effects to system users. One of the reason is that the enhancements do not take effect on the key factors. So there is a question, what factors influence lifespan? A model which can answer this question is needed to help system designers. Facing the challenges, we measure a popular BitTorrent system with a macro view which is different from previous works. Based on our measurement, we model the long term evolution to find out factors that influence swarm lifespan. In order to unveil the trend of a swarm, we propose a half-life based metric. According to the metric, our model fits the real swarms more closely. By the help of our model, we analyze the strengths and shortcomings of bundling technique and SRE incentives. \u00a9 2011 IEEE.",

First, different operational modes of a grid-parallel MG are analyzed and sorted. Normally, the MG will connect with the energy deliver system most of the time, providing functions such as peak shaving, system reserve. But it is also required to operate separately from the grid in planned or unplanned island mode due to different reasons, e.g., power outage, abnormal weather. Then, a multi-objective optimization method to size MG based on different operational scenarios study is proposed. The objectives consist of MG construction and operation cost, reliability cost, ancillary values, utilization of renewable energy and emission. An improved customer outage cost analysis method is demonstrated taking power outage reasons and reliability requirement of load into consideration. A demonstration MG considered in this paper consists of PV, wind turbine (WT), diesel generator, converter and battery energy storage. The results prove that the method presented is sound and effective. \u00a9 2011 IEEE.",

A kind of on-line monitoring method based on wavelet analysis and acoustic emission was raised and the nonlinear relation model between AE RMS,wavelet energy coefficients and wheel passivation state was built. During the process,the wavelet analysis method was used to decompose the original signals for extracting wavelet energy coefficients. The results of experiments indicates that AE RMS increases with increasing table speed;The corresponding relation between AE RMS and table speed is good and could take the table speed as the main parameter for studying wheel passivation state. As a result, the nonlinear relation model can monitor the wheel passivation degree on-line accurately through training. This provides a kind of viable method which has very high practical value for confirming the wheel dressing cycle. \u00a9 2011 Trans Tech Publications.",

        "title": "Constructing a robust protein-protein interaction network by integrating multiple public databases",
        "abstract": "Background: Protein-protein interactions (PPIs) are a critical component for many underlying biological processes. A PPI network can provide insight into the mechanisms of these processes, as well as the relationships among different proteins and toxicants that are potentially involved in the processes. There are many PPI databases publicly available, each with a specific focus. The challenge is how to effectively combine their contents to generate a robust and biologically relevant PPI network.Methods: In this study, seven public PPI databases, BioGRID, DIP, HPRD, IntAct, MINT, REACTOME, and SPIKE, were used to explore a powerful approach to combine multiple PPI databases for an integrated PPI network. We developed a novel method called k-votes to create seven different integrated networks by using values of k ranging from 1-7. Functional modules were mined by using SCAN, a Structural Clustering Algorithm for Networks. Overall module qualities were evaluated for each integrated network using the following statistical and biological measures: (1) modularity, (2) similarity-based modularity, (3) clustering score, and (4) enrichment.Results: Each integrated human PPI network was constructed based on the number of votes (k) for a particular interaction from the committee of the original seven PPI databases. The performance of functional modules obtained by SCAN from each integrated network was evaluated. The optimal value for k was determined by the functional module analysis. Our results demonstrate that the k-votes method outperforms the traditional union approach in terms of both statistical significance and biological meaning. The best network is achieved at k=2, which is composed of interactions that are confirmed in at least two PPI databases. In contrast, the traditional union approach yields an integrated network that consists of all interactions of seven PPI databases, which might be subject to high false positives.Conclusions: We determined that the k-votes method for constructing a robust PPI network by integrating multiple public databases outperforms previously reported approaches and that a value of k=2 provides the best results. The developed strategies for combining databases show promise in the advancement of network construction and modeling. \u00a9 2011 Swamy et al; licensee BioMed Central Ltd.",

        "title": "Meso-scale oriented simulation towards virtual process engineering (VPE)-The EMMS Paradigm",
        "abstract": "With the dramatic development of computational science and technology, computer simulation is playing an increasingly important role in scientific research and engineering practice, and is believed to bring about a profound revolution to the mode and means of these activities. For chemical engineering, it will promote the transition from an experience-and-experiment-based research and development mode to the one based on virtual process engineering (VPE). However, such a revolution still requires tremendous improvements in the Accuracy of physical modeling and numerical methods, the Capability of the computing hardware and software, and the Efficiency of the simulation activities, or in short, ACE. This article will systematically review the 3-decade endeavors at IPE, CAS (Institute of Process Engineering, Chinese Academy of Sciences) on upgrading ACE by establishing a multi-scale computing paradigm focusing on meso-scale structures. We also report recent developments in this direction with projections on future work. Meso-scales refer to the intermediate scales at which the discrete elements in a system interact to shape the global behavior of the system. Reasonable description of the structures at such scales is a bottleneck for reliable and accurate modeling of global behaviors. To address this problem, we started from gas-solid flow by proposing the energy minimization multi-scale (EMMS) model to quantify the hydrodynamics of meso-scale structures in gas-solid fluidization. This model, that is, its stability condition, was thoroughly analyzed and verified with the pseudo-particle modeling (PPM) method. Other systems, such as turbulence and gas-liquid flow, were then studied following the same strategy, revealing the ubiquity of stability conditions for meso-scale structures as a result of the compromise among different dominant mechanisms, and leading to a generalized model mathematically formulated as a multi-objective variational (MOV) problem. Meanwhile, along with wider industrial applications of the EMMS-based simulation methods, common features were recognized that ACE requires structural consistency among the simulated system, the physical model, the numerical software and the computing hardware under the umbrella of MOV, which we have named as the EMMS Paradigm. The EMMS Paradigm was first implemented from the software level using traditional computing hardware to achieve Accuracy. Since 2007, with the development of general-purpose GPU (graphic processing unit) computing, CPU (central processing unit)-GPU hybrid computing was deployed to implement the Paradigm from the hardware level, boosting the Capability to Petaflops range. In applying the Paradigm to the development of an industrial petro-chemical process (maximizing iso-paraffins, MIP), enabling technologies such as pre- and post-processing, error-tolerance, network-based computing and seamless integration of different simulation methods are now under development, which will greatly improve the Efficiency. A demonstration virtual laboratory featuring the comparison and interaction of online measurement and real-time computing is under construction. With these endeavors, an industrial process could be simulated globally in almost real-time, and different levels of details could be traced from the global distribution of flow parameters in a reactor to the inner-channels of catalytic particles at a perceivable evolution speed. The realization of VPE is, therefore, in the foreseeable future. \u00a9 2011 Elsevier Ltd.",

Firstly, image is segmented into many small homogeneous regions by Mean Shift pre-segmentation algorithm, and the homogeneous regions are used to build an undirected graph, instead of pixels. Color histogram is used as a descriptor to represent the region color feature statistics, and Euclidean distance and Gaussian weighting function are used to describe the similarity of adjacent regions. Finally, the discrete potential theory is used to calculate the potential of each node in the graph, and the final image segmentation can be achieved according to the greatest potential of each node in the graph. The results of experiments demonstrate that the segmentation accuracy and efficiency of our proposed method is improved significantly comparing with traditional random walker algorithms.",

The simulation model was improved both in steady operating points and transient process with the experimental data of a practical microturbine generation system. The microturbine input of variables nonlinear combination enhanced the microturbine output accuracy in steady state. The relevant parameters were calculated through data fitting based on the input-output relationship. The rate limiter, which reflected the delay characteristic of thermodynamic process, was applied in the power commands of the microturbine and inverter to improve the dynamic fit. Finally, the comparison between experimental data and simulation results verified the applicability and effectiveness of the model proposed in this paper.",

        "abstract": "According to the current status of the Chinese VLBI network and through data simulation, the effect of the orbit prediction error, the white noise and systematic errors in VLBI delays and ranging errors on the positioning reduction of spacecraft is analyzed. Results show that it is preferable to suppress the dispersion of positioning data points by applying constraint of geocentric distance of spacecraft when there is only VLBI tracking data. The positioning solution with observations of three VLBI stations is a biased estimate. For the case of four tracking stations the uncertainty of the constraint should be in accordance with the orbit prediction error. If the uncertainty is too large then the effect of suppression on the dispersion of positioning points would be limited. If it is too small then some systematic offset would be led into the positioning results. White noises in delay and ranging mainly result in dispersion of positioning data points. While systematic errors in observations result in systematic offsets in the positioning results, and there are trend asymptotic line jumps in the sequence of positioning points, which could also be taken as a criterion for the existence of systematic errors in observations. In addition, at the moment when VLBI stations change from three to four or vice versa, there may exist the trend jump in the sequence of positioning points. The analysis in this paper could provide a reference for the positioning reduction of spacecraft in the follow-on lunar exploration and the Yinghuo project.",

        "abstract": "Lazy learning, such as k-nearest neighbor learning, has been widely applied to many applications. Known for well capturing data locality, lazy learning can be advantageous for highly dynamic and complex learning environments such as data streams. Yet its high memory consumption and low prediction efficiency have made it less favorable for stream oriented applications. Specifically, traditional lazy learning stores all the training data and the inductive process is deferred until a query appears, whereas in stream applications, data records flow continuously in large volumes and the prediction of class labels needs to be made in a timely manner. In this paper, we provide a systematic solution that overcomes the memory and efficiency limitations and enables fast lazy learning for concept drifting data streams. In particular, we propose a novel Lazy-tree (Ltree for short) indexing structure that dynamically maintains compact high-level summaries of historical stream records. L-trees are M-Tree [5] like, height-balanced, and can help achieve great memory consumption reduction and sub-linear time complexity for prediction. Moreover, L-trees continuously absorb new stream records and discard outdated ones, so they can naturally adapt to the dynamically changing concepts in data streams for accurate prediction. Extensive experiments on real-world and synthetic data streams demonstrate the performance of our approach. \u00a9 2011 IEEE.",

For example, in real-time news topic analysis, it is necessary to combine multiple news report streams from dierent media sources to discover collaborative frequent patterns which are reported frequently in all media, and comparative frequent patterns which are reported more frequently in a media than others. To address this problem, we propose a novel frequent pattern mining algorithm Hybrid-Streaming, H-Stream for short.

Existing research efforts on Cloud computing were all focused on designing advanced storage and query techniques for static data. None of them consider the problem that data in a Cloud may appear as continuous and rapid data streams. To address this problem, in this paper we propose a new LCN-Index framework to handle continuous data stream queries in the Cloud. LCN-Index uses the Map-Reduce computing paradigm to process all the queries. In the Mapping stage, it divides all the queries into a batch of predicate sets which are then deployed onto mapping nodes using interval predicate index. In the reducing stage, it merges results from the mapping nodes using multi attribute hash index. In so doing, a data stream can be efficiently evaluated by traversing through the LCN-Index framework. Experiments demonstrate the utility of the proposed method. \u00a9 2011 ACM.",

Especially, the decoding and forward (DF) mode of TWR with PLNC is being investigated for its avoiding of noise amplification compared to that amplify and forward (AF) mode. However, most discussions are concentrated on symmetric modulations, and the influence of the transmitters power matching has not been taken into account. In this paper, we analyze the asymmetric modulation PLNC of TWR taking DF mode and its power matching problem.

The symbol error rate (SER) performance of TWR in time-slot 1 and those of receivers in time-slot 2 are de rived respectively, and the corresponding optimum power matching ratio is also evaluated.

In this paper, we propose Biprominer1, a tool that can automatically extract binary protocol message formats of an application from its real-world network trace. In addition, we present a transition probability model for a better description of the protocol. The chief feature of Biprominer is that it does not need to have any priori knowledge of protocol formats, because Biprominer is based on the statistical nature of the protocol format.

To investigate the effect of next generation sequencing technology in profiling circulating miRNA, We detected maternal plasma miRNAs expression profiles using SOLiD sequencing platform. The results showed that the distribution and abundance of specific miRNAs in plasma are varying during physiological pregnancy process. The functions of target genes of those abundant plasma miRNAs implied that these miRNAs may involve in regulation of some physiologic processes, such as inflammatory process, muscle differentiation, insulin resistance. This study proved SOLiD sequencing technology is an effective method for circulating miRNAs expression profiling.

In order to decrease the distortion at low computation cost, this paper proposed a new data hiding algorithm by introducing an in-loop compensation scheme. It utilized the prediction information decoded from original compressed video to re-encode the video, and then embedded the concealed data into DC coefficients of intra-4x4 macro-blocks inside I-frames during the new encoding process. Simulation results show that, the proposed scheme can embed large data into H.264/AVC stream with imperceptible distortion and nearly no stream size amplification. \u00a9 2011 IEEE.",

It composes traditional HTTP/FTP downloading and P2P content distribution features which attract many people including researchers. Xunlei's network is BitTorrent-like and the measurement is more difficult than other P2P networks [2]. There are many constrains on Xunlei tracker, so we can not obtain information from tracker easily. Besides this, the measurement will encounter some challenges that skew the results. Most of previous works on BitTorrent system are based on tracker logs. However, we can not obtain tracker logs of Xunlei. As far as we know, there is no proposal about precise and detailed measurement method that probes the network directly in this area. Face to the challenges, we analyze the constrains that appear in most BitTorrent-like systems and propose a stratified random selection model to describe the behavior of tracker. Based on the model, we design a measurement tool called XunleiProbe. With the help of our solutions that increase the accuracy of our results, we measure a popular swarm for about 22 hours. The results show that the average peer coverage of our tool can reach about 93%. \u00a9 2011 IEEE.",

However, these systems all rely on dedicated infrastructure and entry points for service accessibility. The network infrastructure and entry points may become the target of censorship attack. In this paper, a UGC-based method is proposed (called user-generated content based covert communication, UGC3) for covert communication in a friends-to-friends (F2F) manner. It uses existing infrastructures (i.e., UGC sites) to form a fully distributed overlay network. An efficient resource discovery algorithm is proposed to negotiate the rendezvous point. Analysis shows that this method is able to circumvent internet censorship with user repudiation and fault tolerance. \u00a9 2011 IEEE.",

It is not only significantly widens the applicability of super-resolution methods to a broad variety of video containing complex motions, but also yields a unique idea of SR reconstruction.

        "title": "Bioimmunological characteristics of mature or immature murine dendritic cells",
        "abstract": "Objective: To explore the biological characteristics of immature and mature murine bone marrow-derived dendritic cells (DCs). Methods: The murine bone marrow cells were cultured and induced in vitro into immature DCs (imDCs). Then ImDCs were incubated with TNF (tumor necrosis factor)-\u03b1 to obtain mature DCs (mDCs). The DCs were purified by murine CD11c microbeads. The morphologies of DCs were observed by electron microscopy (EM). Such surface markers as MHC-II, CD80 and CD86 were tested by flow cytometry (FCM). The proliferation capacity of allogeneic T cells stimulated by DCs was examined by Cell Counting Kit-8 (CCK-8) in mixed lymphocyte reaction (MLR). The expressions of cell factors in mRNA of DCs were tested by real-time polymerase chain reaction (QPCR). The cytokines in supernatant were measured by ELISA (enzyme-linked immunosorbent assay). Results: As compared with mDCs, fewer, shorter spines and more phagocytic vesicles and lysosome were observed in imDCs under EM. The expressions of cell surface molecules in imDCs were significantly lower than those of mDC by FCM, [MHC-II(27.2%)vs(97.7%); CD80(27.6%) vs(97.2%); CD86(29.5%) vs(96.4%)]. In MLR, the capacity of same-reaction ratio imDCs group for stimulating the proliferation of T-cells was remarkably lower than that of mDCs group, [1:5 (1.63 \u00b1 0.04) vs (2.21 \u00b1 0.09); 1:10 (1.50 \u00b1 0.08) vs (1.92 \u00b1 0.02); 1:20 (1.28 \u00b1 0.07) vs (1.64 \u00b1 0.01); 1:40 (1.19 \u00b1 0.04) vs (1.45 \u00b1 0.06), P < 0.01]. In imDCs, the relative mRNA expressions of IL12p35 (0.66 \u00b1 0.13), IL12p40 (0.57 \u00b1 0.10) and IFN-\u03b3 (0.74 \u00b1 0.08) were lower than those of mDCs (1.00 \u00b1 0.00), (P < 0.05), but the expression of TGF-\u03b2 (1.35 \u00b1 0.09) was higher than that of mDCs by QPCR (1.00 \u00b1 0.00), (P < 0.05). The expressions of IL12p70 and IFN-\u03b3 in supernatants from imDCs were lower than those of mDCs[IL12p70: (6 \u00b1 4) vs (120 \u00b1 22); IFN-\u03b3: (56 \u00b1 15) vs (90 \u00b1 15), P < 0.05] while the expression of TGF (transforming growth factor)-0 was higher than that of mDCs by ELISA [TGF-\u03b2: (176 \u00b1 23) vs (55 \u00b1 18), P < 0.05]. Conclusion: ImDCs can induce anergic T cells and immune tolerance through a down-regulation of co-stimulatory molecules, MHC-II and Th1 cytokines and an up-regulation of Th2 cytokine (TGF-\u03b2). And MDCs may activate naive T cells and stimulate immune responses by an up-regulation of co-stimulatory molecules, MHC-II and Thl cytokines.

Spacing design of adjacent cutters not only is related to the boundary conditions and rock as well as the cutter and cutter parameters of the tunneling parameters, but also couples with the cutter structure interaction; it is a sequential process of broken rock. Based on the finite element simulation platform of rock crushing-Rock Failure Process Analysis (RFPA2D), considering the adjacent multi-cutters sequential constraints, taking two typical rocks (muddy pink sandstone and granite gneiss) as boundary conditions, smoother hob times under the vertical pressure into the rock crushing simulation model were constructed. This simulated how the multi-cutters in the sequential and simultaneous pressure pushed the rock into the simulation process. The mapping between disc cutters spacing and rock fragmentation energy was established, and thereby a mapping between multi-cutters sequential location angle and the energy of rock fragmentation was established during spacing of the optimal cutters. The cutters' optimal spacing and the optimal sequential angle in a different location can be determined through this mapping, and it can also provide the design basis for the layout design of future cutters.",

        "abstract": "An improved harmony search algorithm (IHS) was proposed and used in clustering analysis. The feedback mechanism was introduced first into the harmony search algorithm, and harmony memory considering rate and bandwidth can be dynamically adjusted by calculating the difference between the best harmony and the worst harmony, which makes the IHS converge to the global optimal solution quickly. The proposed algorithm updates the decision variables which represent the cluster centers to minimize the value of objective function and get the best partition of data samples. A method which can automatically determine the true number of clusters of data samples was then proposed, the true number of clusters was calculated when the input number of cluster center is greater than the true number of clusters. Finally, four performance measures were used to compare the proposed algorithm with ANT-based and traditional harmony search (HS) based clustering analysis algorithms, it is shown that the performance of the proposed algorithm is better than the other two algorithms.",

        "abstract": "Mining hot topics from twitter streams has attracted a lot of attention in recent years. Traditional hot topic mining from Internet Web pages were mainly based on text clustering. However, compared to the texts in Web pages, twitter texts are relatively short with sparse attributes. Moreover, twitter data often increase rapidly with fast spreading speed, which poses great challenge to existing topic mining models. To this end, we propose, in this paper, a flexible stream mining approach for hot twitter topic detection. Specifically, we propose to use the Frequent Pattern stream mining algorithm (i.e. FP-stream) to detect hot topics from twitter streams. Empirical studies on real world twitter data demonstrate the utility of the proposed method. \u00a9 2012 Published by Elsevier Ltd.",

A feasible numerical method is required to predict chloride penetration in concrete structures. A transient meshless boundary element method is proposed to predict chloride diffusion in concrete with time dependent nonlinear coefficient. Taking Greens function as the weighted function, the weighted residue method is adopted to transform the diffusion equation into equivalent integral equations. By the coupling of radial integral method and radial basis function approximation, the domain integrals in equivalent control equations are transformed into boundary integrals. Following the general procedure of boundary element meshing and traditional finite difference method, a set of nonlinear algebraic equations are constructed and are eventually solved with the modified Newtonian iterative method. Several numerical examples are provided to demonstrate the effectiveness and efficiency of the developed model. A comparison of the simulated chloride concentration with the corresponding reported experimental data in a real marine structure indicates the high accuracy and advantage of the time dependent coefficient and nonlinear model over the conventional constant coefficient model. \u00a9 2011 Elsevier Ltd.

Here, we attempted to track detailed miRNA precursor metabolic products and gain further insight into pre-miRNA processing by completely analyzing high-throughput sequencing data. Highly expressed miRNA precursors could be entirely covered by various short RNAs and small RNA fragments with a hierarchical distribution. miRNAs and some miRNA* regions were detected quite abundant short RNAs as expected, while other regionsofprecursors were found shorter RNAs or small fragments with fewer sequence counts. Furthermore, we developed a method to analyze relative expression levels of special RNA classes according to divergence of 5\u2032 and 3\u2032 ends, respectively. Generally, there were several quite abundant RNA classes from a given miRNA locus, which suggested dominant cleavage sites ofDrosha and Dicer during pre-miRNA processing. Compared with 3\u2032 end, dominant cleavage site in 5' end always focused on a specific position, which ensured conservation of the identity of miR-NA (5'-seed sequence, nucleotides 2-8). Overall, a comprehensive analysis of sequencing data can be used to track pre-miRNA metabolic products and mechanism of pre-miRNA processing and metabolism. \u00a9 2011 Springer Science+Business Media B.V.",

An improved random walker algorithm was proposed to solve the above problems. Firstly, according to the probability that calculated by Dirichlet boundary condition, the image will be divided into three parts: objective region, background region and uncertain region. Euclidean distance was used to calculate the difference between the nodes in the uncertain region and the seed, which can be used to label nodes in the uncertain region. Secondly, a parabola between two points algorithm (PBTP) for the second segmentation was proposed to achieve the final image segmentation.

        "abstract": "Objective: Recently, microRNAs (miRNAs) had been shown as potential important regulators in pregnancy. Circulating miRNAs are considered as potentially useful non-invasive biomarkers for the diagnosis of pregnancy-related disease and congenital disorders, but maternal peripheral blood miRNAs expression profile in pregnancy remains less investigated. We thus set out to investigate maternal plasma miRNAs expression profile using genome-wide sequencing. Methods: Maternal plasma miRNA expression profiles of different pregnancy stages were detected by SOLiD sequencing. We observed the expression level of the most abundant miRNAs in maternal plasma during pregnancy process. We examined functional relationships of targets of pregnancy-relative miRNAs by enrichment analyzing of signaling pathways. Results: 147 miRNAs were sequenced from maternal plasma in this study, among them, 90 types of miRNAs were found in all of the samples, while 136 miRNAs in the first trimester gestation, 108 in second trimester gestation, and 99 miRNAs in the third trimester gestation, respectively. The varieties and the expression level of maternal plasma miRNAs were changing during pregnancy. The expression level of miRNA cluster members was changing with the same trend during pregnancy. The function and functional relationship analysis of target genes of pregnancy-relative miRNAs showed that genetic disorder, immunological disease, cell signaling, cancer, and cell cycle were the enriched pathways. Conclusions: Maternal plasma miRNA expression profiles are dynamically changing during pregnancy. The results of function analysis suggested that miRNAs may play an important role in regulating pregnancy process, which can help us understand the refine regulation mechanism in pregnancy. Moreover, the results of this present study may be the basis for a further study to find useful prenatal diagnosis biomarkers. \u00a9 2011 Elsevier B.V.",

        "abstract": "The term RNA silencing (RNA interference, RNAi) describes a set of mechanisms that regulate gene expression in eukaryotes. Small interfering RNAs (siRNA) and microRNAs (miRNAs) are two major types of RNAi-associated small RNAs (smRNAs) found in most eukaryotic organisms. Despite the presence of a plethora of non-coding RNAs longer than 50-nucleotide (nt) in length in various species of Archaea, little is known about smRNAs in archaea that resemble the 20-24-nt long smRNAs found in eukaryotes, which have been implicated in the post-transcriptional control of gene expression. Here, we report the finding of a large number of smRNAs approximatelly 20-nt in length, including phased smRNAs and potential miRNAs, from the hyperthermophilic archaeon Sulfolobus solfataricus p2 (Ssp2) based on deep sequencing. The expression of some of the miRNA candidates in Ssp2 was confirmed. Consistent with the Ssp2 hyperthermophilic properties, we found that higher temperatures more efficiently induced the production of the miRNA candidates in an in vitro system using the putative foldback precursor transcripts incubated with Ssp2 extract. Although we initially predicted putative target genes of some miRNA candidates, further analysis mapped the cleavage sites downstream of the miRNA candidate complementary regions, similar to those involved in plant miRNA-mediated TAS transcript cleavage. We also identified smRNAs from clustered, regularly interspaced, short palindromic repeat (CRISPR) loci, which play important roles in prokaryotic microbial defense systems. Archaea represent a unique life form next to Bacteria and Eukarya, and our results may provide a useful resource for further in-depth study on the regulation and evolution of smRNAs in this special organism. \u00a9 2012 Xu et al.",

Major advances have been made in the understanding of the mechanism of some subtypes. GBS is thought to be due to autoimmunity for which immunotherapy is usually prescribed. About 20% patients died or had persistent disability despite normative immunotherapy. More research is needed to identify better treatment regimens and new therapeutic strategies.

Under well-founded semantics, all the algorithms are sound and completed, and their computational complexities are polynomial. In this framework, security policy declaration, evaluation and verification are executed under the same semantics, which is significant for security policy management.

        "abstract": "The eukaryotic-like primase from the hyperthermophilic archaeon Sulfolobus solfataricus (SsoPriSL) exhibits a range of activities including template-dependent de novo primer synthesis, primer extension and template-independent terminal nucleotidyl transfer using either rNTPs or dNTPs. Remarkably, the enzyme is able to synthesize products far longer than templates in vitro. Here we show that the long products resulted from template-dependent polymerization across discontinuous templates (PADT) by SsoPriSL. PADT was initiated through either primer synthesis or terminal transfer, and occurred efficiently on templates containing contiguous dCs. Template switching took place when the 3\u2032-end of a growing strand synthesized on one template annealed to another template directly or following the terminal addition of nucleotides, and was subsequently extended on the new template. The key to PADT was the ability of SsoPriSL to promote strand annealing. SsoPriSL catalyzed PADT with either dNTPs or rNTPs as the substrates but preferred the latter. The enzyme remained active in PADT but became inefficient in primer synthesis in vitro when temperature was raised from 55\u00b0C to 70\u00b0C. Our results suggest that SsoPriSL is capable of bridging noncomplementary DNA ends and, therefore, may serve a role in double-strand DNA break repair in Archaea. \u00a9 2011 The Author(s).",

With the proposed syntax structure in this paper, as a full-fledged authorization and access control framework, the AACF naturally possesses some advantages such as nonmonotonic authorization, authorization propagation, and conflict checking and resolution. Furthermore, the computational complexity of the semantic query evaluation (i. e., access control decision) algorithm of the AACF proved to be polynomial. Hence, the AACF has the better expression ability and computing characteristic than the existing ones.",

        "abstract": "Administration of vascular endothelial growth factor (VEGF) has been shown to increase cerebral blood flow and reduce neurological damage after experimental ischemic brain injury. The purpose of this study was to examine the optimal dose and time window for the neuroprotective effect of VEGF when administrated after focal ischemia/reperfusion injury in rabbits. Focal cerebral ischemia/reperfusion was induced by the middle cerebral artery occlusion (MCAO) method. In a dose response experiment, low (1.25 ng/\u03bcL), middle (2.5 ng/\u03bcL) and high (5.0 ng/\u03bcL) doses of VEGF were administered 2 h after MCAO by the route of perifocal region. The VEGF at a dose of middle (2.5 ng/\u03bcL) displayed excellent effects on neuroprotective efficacy for focal cerebral ischemia/reperfusion injury. In another experiment, 2.5 ng/\u03bcL VEGF was administered at times varying from 2 to 8 h after MCAO. Infarct volume, water content and neurological deficits were significantly reduced when VEGF was given at 2 and 3 h after injury. The protective effect was less when the same dose was given at the later times. Thus, the present findings indicated that VEGF reduced ischemic neuronal danger with a therapeutic time window within the first 3 h of transient MCAO and may be useful in the treatment of acute ischemic stroke in humans. \u00a9 2012 Elsevier Ltd.

In all living cells, chromatin proteins serve a crucial role in maintaining the integrity of the structure and function of the genome. An array of small, abundant and basic DNA-binding proteins, considered candidates for chromatin proteins, has been isolated from the Euryarchaeota and the Crenarchaeota, the two major phyla in Archaea. While most euryarchaea encode proteins resembling eukaryotic histones, crenarchaea appear to synthesize a number of unique DNA-binding proteins likely involved in chromosomal organization. Several of these proteins (e. g., archaeal histones, Sac10b homologs, Sul7d, Cren7, CC1, etc.) have been extensively studied. However, whether they are chromatin proteins and how they function in vivo remain to be fully understood. Future investigation of archaeal chromatin proteins will lead to a better understanding of chromosomal organization and gene expression in Archaea and provide valuable information on the evolution of DNA packaging in cellular life. \u00a9 2012 The Author(s).",

Here, we performed a comprehensive analysis of isomiR expression patterns and 3\u2032 additions in miRNA gene clusters and families by analyzing high-throughput sequencing dataset. According to dominant modified isomiRs, miRNA members in many miRNA gene clusters and families showed the same 3\u2032 additional nontemplate nucleotides. Although clustered miRNAs and homologous miRNAs had consistent or inconsistent expression levels, we found many of them showed consistent expression patterns at isomiR levels. These findings revealed similar processing mechanism and 3' modification event of miRNAs in gene clusters and families through miRNA maturation process. The consistent maturation mechanism may contribute to co-regulate biological processes, and may originate from ancestral miRNA genes through complex duplication history. \u00a9 2012 Springer Science+Business Media B.V.",

A capacity determination method of energy storage system (ESS) was presented to inhibit the adverse effects of RESs fluctuations on the power grid. The spectrum analysis results of RESs output were obtained through discrete Fourier transform (DFT). The minimum power and energy capacity of ESS can be determined based on the spectrum analysis results. The determined capacity of ESS can satisfy the constraints of charge-discharge efficiency, state of charge (SOC) of ESS and the upper fluctuation rate limit of RESs target output. The proposed method was verified on a wind power generation system based on historical wind speed data of Washington, USA and grid-connected wind farm 20 minutes active power fluctuation standard (upper power fluctuation rate limit is 10%) of Tohoku Electric Power. The results show the maximum 20 minutes active power fluctuation rate of wind power output can be reduced from 61.7% to 9.9% by a relatively small capacity of ESS determined by the presented method. \u00a9 2012 Chinese Society for Electrical Engineering.",

The relays will select amplify-and-forward (AF) or decode-and-forward (DF) according to the signal to interference pulse noise ratio (SINR). The aim of this paper is to maximize the received SINR in the SN with different power constraints and the QoS requirement of the primary user (PU). Numerical results compare the performance of the SN between relays with beamforming and relays without beamforming which indicates that the gap between them is related to the maximum interference power at primary destination, while is irrelevant to maximum the total transmitted power of the relays. Besides there is a tradeoff between the performance of the SN and the number of the relays. \u00a9 2012 IEEE.",

        "title": "A prefiltering approach to regular expression matching for network security systems",
        "abstract": "Regular expression (RegEx) matching has been widely used in various networking and security applications. Despite much effort on this important problem, it remains a fundamentally difficult problem. DFA-based solutions can achieve high throughput, but require too much memory to be executed in high speed SRAM. NFA-based solutions require small memory, but are too slow. In this paper, we propose RegexFilter, a prefiltering approach. The basic idea is to generate the RegEx print of RegEx set and use it to prefilter out most unmatched items. There are two key technical challenges: the generation of RegEx print and the matching process of RegEx print. The generation of RegEx is tricky as we need to tradeoff between two conflicting goals: filtering effectiveness, which means that we want the RegEx print to filter out as many unmatched items as possible, and matching speed, which means that we want the matching speed of the RegEx print as high as possible. To address the first challenge, we propose some measurement tools for RegEx complexity and filtering effectiveness, and use it to guide the generation of RegEx print. To address the second challenge, we propose a fast RegEx print matching solution using Ternary Content Addressable Memory. We implemented our approach and conducted experiments on real world data sets. Our experimental results show that RegexFilter can speedup the potential throughput of RegEx matching by 21.5 times and 20.3 times for RegEx sets of Snort and L7-Filter systems, at the cost of less than 0.2 Mb TCAM chip. \u00a9 2012 Springer-Verlag.",

The gap between the capability of existing computational methods and the capability required for these methods to be useful for engineers is bridged by an energy minimization multiscale (EMMS) model for gas-solid fluidization. The VPE platform based on this model was developed that perform a pseudo real-time simulation of the hydrodynamics of an industrial process. The circulating fluidized bed (CFB) measures the instantaneous axial solids-concentration profile in the riser. VPE 1.0 not only functions as a comprehensive platform to provide basic data and design guidelines for the development of industrial processes, but it could be an effective tool for training new operating staff at much lower cost.",

Firstly, a global spatial similarity measure and a global intensity similarity measure were proposed and introduced into a novel distance metric to calculate the difference between the pixels and the cluster centers. Secondly, color histogram was used as a descriptor, and Bhattacharyya distance was used to calculate the similarity between any two classes. Finally, a maximal similarity based class merging strategy was used to obtain the final image segmentation results.

        "abstract": "Background: Large amounts of mammalian protein-protein interaction (PPI) data have been generated and are available for public use. From a systems biology perspective, Proteins/genes interactions encode the key mechanisms distinguishing disease and health, and such mechanisms can be uncovered through network analysis. An effective network analysis tool should integrate different content-specific PPI databases into a comprehensive network format with a user-friendly platform to identify key functional modules/pathways and the underlying mechanisms of disease and toxicity. Results: atBioNet integrates seven publicly available PPI databases into a network-specific knowledge base. Knowledge expansion is achieved by expanding a user supplied proteins/genes list with interactions from its integrated PPI network. The statistically significant functional modules are determined by applying a fast network-clustering algorithm (SCAN: a Structural Clustering Algorithm for Networks). The functional modules can be visualized either separately or together in the context of the whole network. Integration of pathway information enables enrichment analysis and assessment of the biological function of modules. Three case studies are presented using publicly available disease gene signatures as a basis to discover new biomarkers for acute leukemia, systemic lupus erythematosus, and breast cancer. The results demonstrated that atBioNet can not only identify functional modules and pathways related to the studied diseases, but this information can also be used to hypothesize novel biomarkers for future analysis.Conclusion: atBioNet is a free web-based network analysis tool that provides a systematic insight into proteins/genes interactions through examining significant functional modules. The identified functional modules are useful for determining underlying mechanisms of disease and biomarker discovery.

        "title": "Analysis of serum genome-wide microRNAs for breast cancer detection",
        "abstract": "Objective: Among methods for profiling levels of miRNAs, next-generation sequencing (NGS) has an effective one for genome-wide profiles, which not only can accurately quantify known miRNAs expression, but also discovery novel miRNAs. In this paper, we investigated that whether specific miRNAs were co-expressed in the serum and tissue of breast cancer (BC) patients as novel biomarkers by SOLiD sequencing. Methods: Different miRNA expression profiles of serum and tissue in breast cancer patients and control subjects were obtained by NGS -SOLiD sequencing. Real-time PCR was used to selected and validated candidate miRNA-biomarkers. Novel miRNAs were predicted by computational pipeline, and validated by Northern blot analysis. Results: Of genome-wide miRNA analysis using SOLiD sequencing, 7 miRNAs were found to be co-upregulated (i.e., miR-103, miR-23a, miR-29a, miR-222, miR-23b, miR-24 and miR-25). miR-222 was significantly increased in the serum of BC patients by further validation(P < 0.05), which may be a useful biomarker for differentiating BC patients from controls with receiver operating characteristic (ROC) curve area 0.67 of (95% CI = 0.5649 to 0.7775). A novel miRNA, named miR-BS1 was preliminarily identified and validated. Pre-miR-BS1 has a characteristic secondary structure. Mature miR-BS1 expression was detected in MCF-7 and MDA-MB-231 cells. Through gene ontology analysis, predicted target genes of miR-BS1, such as FOXO3 and KRAS, were involved in cancer-related signaling pathway. Conclusions: This study presented a connection between serum- and tissue- based miRNA of breast cancer which suggested that serum-miRNAs may be potential biomarkers for BC detection. And next-generation sequencing will provide a robust platform for miRNA profilings. \u00a9 2012 Elsevier B.V.",

It is found from the comparisons that the LES with an eddy-viscosity subgrid scale (SGS) model over-predicts the space-time correlations than the DNS. The overpredictions are further quantified by the integral scales of directional correlations and convection velocities. A physical argument for the overprediction is provided that the eddy-viscosity SGS model alone does not includes the backscatter effects although it correctly represents the energy dissipations of SGS motions. This argument is confirmed by the recently developed elliptic model for space-time correlations in turbulent shear flows. It suggests that enstrophy is crucial to the LES prediction of spacetime correlations. The random forcing models and stochastic SGS models are proposed to overcome the overpredictions on space-time correlations. \u00a9 The Chinese Society of Theoretical and Applied Mechanics and Springer-Verlag Berlin Heidelberg 2012.",

Here, PU's QoS is represented by its rate outage probability and it also reflects on the interference temperature (IT). It is equivalent to say that CUs can increase transmit power to enhance the system performance as long as PU's outage probability does not exceed the predefined threshold. We assume that the cognitive base station (CBS) is equipped with M antennas and all CUs has one antenna that means CBS can at most allow M CUs to access simultaneously. We focus on user scheduling schemes for this uplink of multiple user single-input multiple-output (MU-SIMO) system in cognitive radio network (CRN). Meanwhile, we formulate the water-filling power allocation problem at that condition. The first scheduling algorithm is proposed to maximize the system throughput through utilizing the multi-user diversity and spatial multiplexing gain. Due to the first algorithm which does not take the fairness among CUs into account, so we propose the second scheduling algorithm with considering fairness among CUs. It provides a satisfactory tradeoff between maximizing the system performance and achieving fairness among CUs. Finally, these proposed algorithms are validated through extensive simulations.",

Previous grouping algorithms are heuristic or are done by brute-force, which have poor grouping results. This paper analyzes the reasons of states explosion and summarizes conflicting relationship among regular expressions of some types. When conflicts are non-negative and independent, the optimum k-grouping problem of regular expression sets can be reduced to the maximum k-cut problem, which is NP-hard. Based on the idea of local searching, a new grouping algorithm named GRELS is introduced to solve the problem efficiently, which is 1/(1-1/k) -approximation for maximum k-cut problem. Comparing with previous grouping algorithms, GRELS has the minimum number of states for the same number of groups, and requires the least time to update grouping results when pattern sets change. \u00a9 2012 ISCAS.",

To avoid short-term outage that happens when the main power source in the micro-grid changes from the diesel generators to energy storage system or from energy storage system to the diesel generators, the seamless transition control strategy of the diesel generators and energy storage system was proposed.

In this paper, the parameters of DC/DC and DC/AC controllers were designed respectively via classical control theory; in addition, the small-signal stability analysis was presented through eigenvalue theory based on the state-space model; moreover, a combination feedforward method of power balancing and time-delay compensation (a first derivative element) had been proposed, with the purpose to eliminate/minimize the DC bus voltage fluctuations and impact on the DC bus capacitor. Experimental results indicate that the system dynamic and steady performances obtained are consistent with the theoretical analysis, and the improved feedforward compensation method can effectively suppress transient voltage fluctuations and impact on the DC bus capacitor, and speed up system dynamic response. \u00a9 2012 Chinese Society for Electrical Engineering.",

A few benchmark numerical examples are performed to test both the accuracy and efficiency of the developed model in analyzing chloride diffusion in concrete. These examples clearly demonstrate that high diffusivity of ITZs, primarily because of its porous microstructure, tends to accelerate chloride penetration along concentration gradient.

Relevant applications include network traffic monitoring, sensor network data analysis, Web click stream mining, power consumption measurement, dynamic tracing of stock fluctuations, to name a few. Data stream classification in such real-world applications is typically subject to three major challenges: concept drifting, large volumes, and partial labeling. As a result, training examples in data streams can be very diverse and it is very hard to learn accurate models with efficiency. In this paper, we propose a novel framework that first categorizes diverse training examples into four types and assign learning priorities to them. Then, we derive four learning cases based on the proportion and priority of the different types of training examples. Finally, for each learning case, we employ one of the four SVM-based training models: classical SVM, semi-supervised SVM, transfer semi-supervised SVM, and relational . k-means transfer semi-supervised SVM. We perform comprehensive experiments on real-world data streams that validate the utility of our approach. \u00a9 2012 Elsevier B.V..",

        "abstract": "The eigenvoice-based speaker verification method can compensate for voice mismatch in text-independent speaker verification applications, but it does not compensate channel mismatch, which also exerts a negative impact on the verification. Therefore channel mismatch compensation based on eigenvoice method was proposed. First, eigenvoice was adopted to compensate voice mismatch, then WCCN was applied to compensate channel mismatch. After these compensations, the speaker factor was computed and acted as speaker model. Based on the speaker factor model, Cos-score calculation was conveniently used to test verification operation. The experiment results show better performance, with an improvement by 22. 85% at EER and 31. 22% at MinDCF, while compared with GMM-UBM-SVM, an improvement was achieved by 9. 14% at MinDCF. Meanwhile, the new method needs less storage space, which benefits practical applications.",

        "abstract": "Regular expression (RegEx) matching plays an important role in various network, security and database applications. Deterministic finite automata (DFA) is the preferred representation to achieve online RegEx matching in backbone networks, because of its one single pass over inputs for multiple RegExes and guaranteed performance of O(1) memory bandwidth per symbol. However, DFA may occupy prohibitive amounts of memory due to the explosive growth in its state size. In this work, we propose Series DFA (SDFA) to address the problem. The main idea is to cut a complex RegEx into several ordered and small RegExes carefully, and then concatenate their compact DFAs in series to match. Experimental results show that SDFA can achieve significant reduction in memory size at the cost of limited number of memory bandwidth. \u00a9 2012 Springer-Verlag.",

To avoid short-term outage when the main power source in the micro-grid changes from the DGs to BSS or from the BSS to the DGs, a seamless transition control strategy for the DGs and BSS is presented.

Some proposals even demonstrate its potential for on-line early traffic classification - using the first 4-6 data packets at the beginning of a TCP connection to identify the corresponding application. Nevertheless, the related accuracy issues on early classification are still unclear when forged packets exist. The performance of such mechanism under malicious environment, where sophisticated forged data packets injection techniques are presented, had not been addressed. This work aims to touch the above issues, especially when forged packets are inserted before actual application transaction started. Our contributions are two-folded: (1) confirm the discrimination power of early classification as revealed by previous study; (2) explore it's accuracy vulnerability to forged packets - the experiments on both simulated and real SSH tunnel traces show the accuracy declines when forged packets are injected. Our findings show that the intellective early classification methods still deserve further investigation before actual deployment. \u00a9 2012 IEEE.",

        "title": "A risk score based on get with the guidelines-stroke program data works in patients with acute ischemic stroke in China",
        "abstract": "Background and Purpose-There are few validated models for prediction of in-hospital mortality after acute ischemic stroke. In 2010, Smith et al developed and internally validated models for predicting in-hospital mortality based on Get With the Guidelines-Stroke program data. We demonstrate the applicability of this Get With the Guidelines risk model in Chinese patients. Methods-The prognostic model was used to predict survival in 7015 patients with acute ischemic stroke from China National Stroke Registry data set. Model discrimination was quantified by calculating C statistic. To clarify the role of National Institutes of Health Stroke Scale (NIHSS), we also calculated the C statistics for NIHSS alone and for the model without NIHSS. Results-The C statistic was 0.867 (95% CI, 0.839-0.895) through the Get With the Guidelines risk model, suggesting good discrimination in the China National Stroke Registry. The model without NIHSS produced significantly lower C statistic (0.735; 95% CI, 0.701-0.770; P<0.001), indicating the important role of NIHSS in the prediction of survival. Furthermore, a model with NIHSS alone also provided significant discrimination (C statistic, 0.847; 95% CI, 0.816-0.879). A plot of observed versus predicted mortality showed excellent model calibration in the external validation sample from the China National Stroke Registry. Conclusions-The Get With the Guidelines risk model could correctly predict in-hospital mortality in Chinese patients with ischemic stroke. In addition, the NIHSS provides substantial incremental information on a patient's short-term mortality risk and is the strongest predictor of mortality. \u00a9 2012 American Heart Association, Inc.",

However, most existing models were merely focused on mining from single-label data streams. Mining from multi-label data streams has not been fully addressed yet. On the other hand, although some recent work touched the multi-label stream mining problem, they never consider the expensive labeling cost issue, preventing them from real-world applications. To this end, we study, in this paper, a challenging problem that mining from multi-label data streams with limited labeling resource.

However, little is known about these miRNA pairs, especially for their distributions in different animal species. We herein present systematic analysis of them in human, mouse and rat miRNAs, and their expression patterns based on deep sequencing datasets. Methods and results: The phenomenon of miRNA-miRNA interaction could be detected in different animal species. The common miRNAs pairs were found across species. These miRNA pairs could form miRNA:miRNA duplex with complete complementary structure, and were prone to be located on specific chromosomes. They might be homologous miRNA genes (especially in human), or clustered in a gene cluster (especially in rat), or simultaneously detected in different genomic regions due to multicopy pre-miRNAs. Remarkably, some miRNA pairs, located in different genomic regions, also showed complementarity as well as endogenous sense/antisense miRNAs. Based on published deep sequencing datasets, one member of miRNA pairs always was abundantly expressed, whereas another was quite rare. Rare common target mRNAs of these miRNA pairs were predicted. Conclusions: Interaction between miRNAs and significant expression divergence implied complex potential mutual regulatory pattern in the miRNA world. The study would enrich miRNA regulatory network. \u00a9 2012 Elsevier B.V.",

The recursive prediction error (RPE) algorithm based on autoregressive (AR) model has been proven to be more attractive to traditional approaches. However, it adapts too fast in double-talk which may cause the algorithm to diverge. A variable step size (VSS) approach is developed to tackle the problem. On the assumption that prediction error is more than 10 times smaller than microphone signal when the adaptive filter has converged, the step size is adjusted adaptively according to the energies of near-end, far-end and prediction error signals. The experimental results show that our algorithm, compared with original RPE algorithm, the performance in double-talk is improved more than 8 dB while no any performance losses in single-talk and echo path change cases. \u00a9 2012.

To solve this problem, the mathematical models of the converter and its control system is established firstly. The control parameters designing via classical control theory is followed. This is continued with analyzing the cause of the voltage fluctuations. Theoretical analysis points out that the voltage fluctuations can not be completely suppressed or eliminated just via parameters design and steady-state feedforward compensation. As a consequence, we propose an improved control strategy by setting a first derivative element in series to the steady-state feedforward compensation to compensate for the delay of the response. Experimental results indicate that the proposed feedforward compensation method can effectively suppress transient voltage fluctuations, and speed up system dynamic response. \u00a9 2012 IEEE.",

This paper also proposes a control strategy for DC/DC converter with soft-start function, in order to solve the DC bus voltage control under no-load and light-load conditions. Firstly, energy flow of PV/Battery system in both grid-connected mode and stand-alone mode is analyzed, then control strategies for each module under different operation modes is proposed, and the control strategies is verified by actual devices. \u00a9 2012 IEEE.",

Compared with the traditional network, spectrum utilization in CRN will be greatly improved. Meanwhile, in addition to considering the objective QoS metrics during the assessment of network performance, many subjective factors should not be ignored, such as service satisfaction and user experience. So the quality of experience (QoE) can reflect the performance of network more comprehensive than QoS. In this paper, we studied a multi-user beamforming problem in CRN and designed a QoE provisioning model based on a specific QoS-QoE mapping scheme with a comprehensive consideration of techniques in physical layer and the key indicator of performance assessment. The bio-inspired algorithm was utilized to solve the beamforming optimization problem. The simulation results showed that better service satisfaction and higher energy efficiency were gained with the objective of QoE than traditional QoS indicators. \u00a9 2012 IEEE.",

In this paper, we propose ProDecoder, a network trace based protocol message format inference system that exploits the semantics of protocol messages without the executable code of application protocols. ProDecoder is based on the key insight that the n-grams of protocol traces exhibit highly skewed frequency distribution that can be leveraged for accurate protocol message format inference. In ProDecoder, we first discover the latent relationship among n-grams by first grouping protocol messages with the same semantics and then inferring message formats by keyword based clustering and cluster sequence alignment. We implemented and evaluated ProDecoder to infer message format specifications of SMB (a binary protocol) and SMTP (a textual protocol). Our experimental results show that ProDecoder accurately parses and infers SMB protocol with 100% precision and recall. For SMTP, ProDecoder achieves approximately 95% precision and recall. \u00a9 2012 IEEE.",

Several morphing strategies have been proposed as promising approaches, very few works, however, have investigated their impact on the actual traffic classification performance. This work sets out to fulfill this gap from an empirical study point of view. It takes into account different morphing strategies exerted on packet size and/or inter-arrival time. The results show that not all morphing strategies can effectively obfuscate traffic classification. Different morphing strategies perform distinctively, among which the integration of packet size and inter arrival time morphing is the best, and the packet size based method is the worst. The three classifiers also exhibit distinct robustness to the morphing, with C4.5 being the most robust and Naive Bayes being the weakest. In addition, our study shows that classifiers can learn nontrivial information merely from the traffic direction patterns, which partially explains the weakness of packet size based morphing methods. \u00a9 2012 IEEE.",

        "abstract": "Behavior targeting (BT) is a promising tool for online advertising. The state-of-the-art BT methods, which are mainly based on regression models, have two limitations. First, learning regression models for behavior targeting is difficult since user clicks are typically several orders of magnitude fewer than views. Second, the user interests are not fixed, but often transient and influenced by media and pop culture. In this paper, we propose to formulate behavior targeting as a classification problem. Specifically, we propose to use an SVM ensemble for behavior prediction. The challenge of using ensemble SVM for BT stems from the computational complexity (it takes 53 minutes in our experiments to predict behavior for 32 million users, which is inadequate for online application). To this end, we propose a fast ensemble SVM prediction framework, which builds an indexing structure for SVM ensemble to achieve sub-linear prediction time complexity. Experimental results on real-world large scale behavior targeting data demonstrate that the proposed method is efficient and outperforms existing linear regression based BT models. \u00a9 2012 IEEE.",

To guarantee the quality of service (QoS) of the primary user (PU), the interference from the secondary network (SN) has to be lower than what the PU can tolerate. In other words, there is a constraint on the transmit power of the SN. A relay selection criterion is adopted to choose the 'best' relay which retransmits the signal from the transmitter to the destination in the SN. Additionally, interference from the primary network (PN) to the SN is also considered, and its effect on the performance of the SN in terms of outage probability is focused on. Simulation results are provided to show the outage probability of the SN and the effect of the PN on the performance of the SN. \u00a9 2012 NiCT.",

To guarantee the QoS of the primary user (PU), the interference from source and relays in the SN to PU must be lower than what the PU can tolerate. A hybrid relay strategy is adopted by relays that can use amplify-and-forward (AF) or decode-and-forward (DF) strategies to retransmit signal according to signal to interference pulse noise ratio (SINR). The capacity of the source-destination in the SN is maximized with the transmit power and the interference at PU constraints. The simulation results show that the maximum relay transmit power will affect the gain of both the joint beamforming and the hybrid relay strategy, while the maximum interference power at PU will only affect that of the hybrid relay strategy. \u00a9 2012 IEEE.",

        "abstract": "mir-548 is a larger, poorly conserved primate-specific miRNA gene family. 69 human mir-548 genes located in almost all human chromosomes whose widespread distribution pattern implicates the evolutionary origin from transposable elements. Higher level of nucleotide divergence was detected between these human miRNA genes, which mainly derived from divergence of multicopy pre-miRNAs and homologous miRNA genes. Products of mir-548, miR-548-5p, and miR-548-3p showed inconsistent evolutionary patterns, which partly contributed to larger genetic distances between pre-miRNAs. \"Seed shifting\" events could be detected among miR-548 sequences due to various 5\u2032 ends. The events led to shift of seed sequences and target mRNAs, even generated to new target mRNAs. Additionally, the phenomenon of miRNA:miRNA interaction in the miRNA gene family was found. The potential interaction between miRNAs may be contributed to dynamic miRNA expression profiles by complementarily binding events to form miRNA:miRNA duplex with 5\u2032-/3\u2032-overhangs. The miRNA gene family had important roles in multiple biological processes, including signaling pathways and some cancers. The potential abundant roles and functional implication further led to the larger and poorly conserved gene family with genetic variation based on transposable elements. The evolutionary pattern of the primate-specific gene family might contribute to dynamic expression profiles and regulatory network. \u00a9 2012 Tingming Liang et al.",

In particular, IDA first softly divides users involved in a diffusion trace into different communities by topic, and ranks users' influence degrees in these topic communities with activeness, follower-counts, and follower participation-rates (including forwards and comments). In doing so, the top-K influential users for a given item can be obtained w.r.t. different topic communities.

Based on the parameters of an actual project and the strong impact of external excitations, the modal properties and dynamic responses are analyzed, and the cutterhead joint surface loads are obtained and treated by rain flow count. Numerical results indicate that the low natural frequencies are 57 Hz and 61 Hz, and natural vibration modes are pinions-motors rotational mode and translational-overturning coupled mode of cutterhead with inner ring gear correspondingly. Besides, the axial and radial amplitude of dynamic responses are 0.55 mm and 0.25 mm, respectively. The frequencies of radial, torsional, and overturning vibrations are predominantly concentrated in 112 Hz and 120 Hz, which indicates that the vibration responses of cutterhead are mainly affected by the external excitations. Finally, as the rain-flow counting results have shown, the standard deviation of the cutterhead joint surface loads in each direction increases by 12-15 times, compared with that of the external excitations; therefore inertia effect should be considered in cutterhead design. The proposed research lays a foundation for dynamic performance optimization and fatigue crack growth life assessment of cutterhead structure. \u00a9 2013 Wei Sun et al.",

        "abstract": "The traditional motivation behind feature selection algorithms such as a genetic algorithm, a forward stepwise and a backward stepwise selections [1], is to find the best feature subset for a task using one particular learning algorithm. The idea is to select a optimal subset of attributes which are as representative as possible of the original data. However, it has been often found that no single classifier is entirely satisfactory for a particular task. Therefore, how to further improve the performance of these single systems on the basis of the previous optimal feature subset is a very important issue. Ensemble systems, also known as committees of classifiers, are composed of individual classifiers, organized in a parallel way and their outputs are combined in a combination method, which provides the final output of the system. Given the success of ensembles, ensembles allow us to get higher accuracy and sensitivity, which are often not achievable with single models. Based on the above, we propose a practical feature selection approach that is based on an optimal feature subset of a single CAD system, which is referred to as a multilevel optimal feature selection method (MOFS) in this paper. Through MOFS, we select the different optimal feature subsets in order to eliminate features that are redundant or irrelevant and obtain optimal features, and then a bagging ensemble with a MOFS method is proposed. Experimental results indicates that the accuracy of the bagging ensemble using a MOFS method is superior to that of a single CAD system and is also superior to that of the ensemble using an attribute selection algorithm based on ReliefF. \u00a9 2013 IEEE.",

        "abstract": "Roots have important functions in the ecosystem. Therefore, establishing root-related parameters such as root size, biomass, and 3-D architecture is necessary. Traditional methods for measuring tree roots are labor intensive and destructive to nature, limiting quantitative and repeated assessments in long-term research. Ground-penetrating radar (GPR) provides a nondestructive method for measuring tree roots. This study investigates the feasibility of a GPR system with 500-MHz, 900-MHz, and 2-GHz measurement frequencies for detecting tree roots and estimating root biomass under controlled experimental conditions in a sandy area. After energy attenuation correction and velocity analysis, not only the individual root in subsurface is able to be located but also the parameters that correlate well with root biomass can be extracted from the processed GPR data. The major findings were as follows. First, both the amplitude and amplitude-area indices were confirmed to be more effective for estimating root biomass after attenuation-effect compensation. This result suggests that the calibration of GPR wave-attenuation effects and velocity changes with depth are helpful in estimating root biomass from GPR parameters. Second, the selection of GPR system frequency was mainly dependent on field conditions, particularly soil water content. Lower frequency was recommended for developing root biomass estimation model under varied soil conditions. Third, the new method based on the metal reflector experiment was effective and easy to perform in situ for attenuation-effect correction. \u00a9 1980-2012 IEEE.",

        "abstract": "In our previous study, we screened a candidate new microRNA (miRNA) based on the deep sequencing and bioinformatics analysis. In this paper, we evaluated the novel miRNA in the following experiment: 1) the secondary structure of the precursor of novel-miR has the characteristic of a stem-loop hairpin structure, and mature miRNA is far from loops and bulges. 2) we used BLAST (Basic Local Alignment Search Tool) to compare the novel-miR sequence to that found in the GenBank. Novel-miR sequence existed in Mus musculus, Drosophila grimshawi, Rattus norvegicus, Xenopus laevis, Spodoptera frugiperda, Papio anubis, Salmo salar and so on. Then multiple sequence alignment (MSA) showed that sequence from 5 to 11. bp and 13 to 17. bp exhibited 100% similarity, where there is significant sequence conservation. Novel-miR showed similarity in the seed region with the known miR-3675-3p, indicating that these miRNAs are likely to belong to the same family and thus may share common biology. 3) novel-miR from MCF-7 and MB-MDA-231 was validated by Northern blot and detected in the serum and tissue samples of BC patients, respectively, by real-time PCR. The data showed that novel-miR was downregulated in the BC cancerous tissues and serum of breast cancer patients (P. <0.05). 4) transfection of novel-miR mimics into MCF-7 cell significantly inhibited cell growth detected by CCK-8 assay (P. <0.05). 5) to identify the mRNA targets of novel-miR, we performed a computational screen for genes with novel-miR complementary sites in their 3'-UTR using several open access databases. In addition, we used the CapitalBio\u00ae Molecule Annotation System V3.0 to perform gene ontology (GO) analysis on the target genes of novel-miR and specific biological process categories were enriched. 7 genes (CUL3, KRAS, ETS1, MNT, CNTN3, CCNK and FOXO3) which have a high prediction score and are associated with cell proliferation, apoptosis and cell cycle were chosen. 3'-UTR luciferase report assay suggested that miR-BS1 negatively regulated CNTN3. In the conclusion, novel-miR, named miR-3675b, is a true, functional and novel miRNA. Candidate novel miRNA from deep sequencing which will be qualified as a \"real\" miRNA must be validated by a series of functional experiments. \u00a9 2012 Elsevier B.V.",

        "abstract": "This paper studies the cognitive one-way relay network which is composed of a pair of primary transmitter and receiver. A two-step one-way amplify-and-forward (AF) relaying scheme is used by the primary network who utilizes the cognitive radio (CR) terminals as its relay nodes. Simultaneously, the cognitive information is transmitted by multiple CR terminals to the CR base station. In the first phase of AF relaying, the primary signal is forwarded by transmitter to the CRs/relays. The CRs/relays multiple the cognitive signals to the received primary signal and accomplish a distributed beamforming in the second phase of relaying. The authors aim at minimizing the CRs/relays power under the different signal to interference pulse noise ratio (SINR) restraints at the primary receiver and the cognitive base station (BS). The results can be seen from the simulation that the minimum CR terminals/relays power will increase with the rising of the SINR constraints. Besides, the performance difference between CR terminals/relays beamforming and without beam-forming is affected by the minimum CR terminals transmit power and the number of relays. Furthermore, with the number of CR terminals/relays rising, the performance difference is decreasing. \u00a9 2013 IEEE.",

        "abstract": "Background and Scope: Because of the crucial role coarse roots (>2 mm diameter) play in plant functions and terrestrial ecosystems, detecting and quantifying the size, architecture, and biomass of coarse roots are important. Traditional excavation methods are labor intensive and destructive, with limited quantification and repeatability of measurements over time. As a nondestructive geophysical tool for delineating buried features in shallow subsurface, ground penetrating radar (GPR) has been applied for coarse root detection since 1999. This article reviews the state-of-knowledge of coarse root detection and quantification using GPR, and discusses its potentials, constraints, possible solutions, and future outlooks. Some useful suggestions are provided that can guide future studies in this field. Conclusions: The feasibility and accuracy of coarse root investigation by GPR have been tested in various site conditions (mostly in controlled conditions or within plantations) and for different plant species (mostly tree root systems). Thus far, single coarse root identification and coarse root system mapping have been conducted using GPR, including roots under pavements in urban environment. Coarse root diameter and biomass have been estimated from indexes extracted from root GPR radargrams. Coarse root development can be observed by repeated GPR scanning over time. Successful GPR-based coarse root investigation is site specific, and only under suitable conditions can reliable measurements be accomplished. The best quality of root detection by GPR is achieved in well-drained and electrically-resistive soils (such as sands) under dry conditions. Numerous factors such as local soil conditions, root electromagnetic properties, and GPR antenna frequency can impact the reliability and accuracy of GPR detection and quantification of coarse roots. As GPR design, data processing software, field data collection protocols, and root parameters estimation methods are continuously improved, this noninvasive technique could offer greater potential to study coarse roots. \u00a9 2012 Springer Science+Business Media B.V.",

        "abstract": "Dysregulation in the expression of miRNAs contributes to the occurrence and development of many human cancers. We herein attempted to obtain the potential association between miRNA expression profile and breast cancer by applying high-throughput sequencing technology. Small RNAs from seven paired tumor and adjacent normal tissue samples were sequenced. To determine the miRNA expression profiles in tissues and sera, another five equally pooled serum samples from 20 patients and 30 normal women were sequenced. Despite a similar number in abundantly expressed miRNAs across samples, we detected varying miRNA expression profiles. Some miRNAs showed inconsistent or opposite dysregulation trends across different tumor tissues, including some abundantly expressed miRNA gene clusters and gene families. Wilcoxon sign-rank test for paired samples analysis revealed that abnormal miRNAs showed a higher level of variation across the seven tumor samples. We also completely surveyed abnormal miRNAs expressed in tumor and serum tissues in the mixed datasets based on the relative expression levels. Most of these miRNAs were significantly down-regulated in tumor samples, but nine abnormal miRNAs (miR-18a, 19a, 20a, 30a, 103b, 126, 126, 192, 1287) were consistently expressed in tumor tissues and serum samples. Based on experimentally validated target mRNAs, functional enrichment analysis indicated that these abnormal miRNAs and miRNA groups (miRNA gene clusters and gene families) have important roles in multiple biological processes. Dynamic miRNA expression profiles, various abnormal miRNA profiles and complexity of the miRNA regulatory network reveal that the miRNA expression profile is a potential biomarker for classifying or detecting human disease. \u00a9 2012 Springer Science+Business Media Dordrecht.",

The initial-point-guide technology and the duplicate-removal operation are introduced into NSGA-II to improve its convergence performance and the distribution characteristics of its Pareto front.

        "abstract": "mir-17-92 gene cluster is widely distributed in vertebrates and plays an important role in regulating multiple biological processes. Its dysregulation may be associated with risk of some human cancers. The microRNA (miRNA) members are identified in the three gene families: mir-17, mir-19 and mir-25. Herein we attempted to understand the evolutionary processes and patterns in vertebrates. The three miRNA gene families showed difference in distribution, number of miRNA genes and clustered miRNA genes in the five animal species. Compared to other related gene clusters, mir-17-92 cluster was well-conserved and had more abundant roles in multiple biological processes. These clustered miRNAs showed inconsistent nucleotide divergence patterns across different animal species, even between homologous miRNA genes. Simultaneously, they also indicated inconsistent expression patterns although they were co-transcribed as a polycistronic transcript. Phylogenetic tree based on human pre-miRNA sequences showed that mir-19 gene family was an older miRNA species, while tree based on miRNA gene cluster indicated evolutionary positions of different animal species. The study shows dynamic evolution of the mir-17-92 gene cluster and related miRNA gene families across vertebrates, which may be derived from potential functional implication. miRNA gene cluster should be a better phylogenetic marker than a single miRNA gene to reveal functional and evolutionary relationships. \u00a9 2012 Springer Science+Business Media Dordrecht.",

So researches on network access control model, aiming at preventing youngsters from accessing pornography information, have become a hotspot. However, existing models usually don't distinguish between adults and youngsters, and they block all the accesses to pornography information, which does not meet the actual demand. So preventing youngsters from accessing pornography information, while not affecting the freedom of expressions in adults, has become a reasonable yet challenging alternative. In this paper, an access control model based on classification of users' network behaviors is proposed, and this model can effectively make a decision whether to allow one's access to pornography information according to its age. Besides, an evaluation framework is also proposed, through which the model's controllability, cost-effectiveness and users' accessibility are analyzed respectively. \u00a9 2013 Springer-Verlag.",

        "abstract": "Reactive force field (ReaxFF), a recent and novel bond order potential, allows for reactive molecular dynamics (ReaxFF MD) simulations for modeling larger and more complex molecular systems involving chemical reactions when compared with computation intensive quantum mechanical methods. However, ReaxFF MD can be approximately 10-50 times slower than classical MD due to its explicit modeling of bond forming and breaking, the dynamic charge equilibration at each time-step, and its one order smaller time-step than the classical MD, all of which pose significant computational challenges in simulation capability to reach spatio-temporal scales of nanometers and nanoseconds. The very recent advances of graphics processing unit (GPU) provide not only highly favorable performance for GPU enabled MD programs compared with CPU implementations but also an opportunity to manage with the computing power and memory demanding nature imposed on computer hardware by ReaxFF MD. In this paper, we present the algorithms of GMD-Reax, the first GPU enabled ReaxFF MD program with significantly improved performance surpassing CPU implementations on desktop workstations. The performance of GMD-Reax has been benchmarked on a PC equipped with a NVIDIA C2050 GPU for coal pyrolysis simulation systems with atoms ranging from 1378 to 27,283. GMD-Reax achieved speedups as high as 12 times faster than Duin et al.'s FORTRAN codes in Lammps on 8 CPU cores and 6 times faster than the Lammps' C codes based on PuReMD in terms of the simulation time per time-step averaged over 100 steps. GMD-Reax could be used as a new and efficient computational tool for exploiting very complex molecular reactions via ReaxFF MD simulation on desktop workstations. \u00a9 2013 Elsevier Inc.

        "abstract": "In multimedia stream filtering scenario, there usually exist many filtering queries that specify the filtering objectives and many filters that estimate the filtering queries. A filtering query may connect to several different filters and a filter may connect to several different filtering queries. An open problem in such a filtering scenario is how to order the filters in an optimal sequence so as to decrease the filtering cost. Existing methods are based on a greedy strategy which orders the filters according to three factors of the filters, i. e., the selectivity, popularity, and cost. Although all these methods reported good results, there are still some problems that haven't been addressed yet. Firstly, the selectivity factor is set empirically, which can not adaptively adjust with stream passing by. Secondly, the relationships among the three factors are not considerably explored. Under these observations, in this paper, we propose an adaptive hierarchal ordering (AHO) algorithm which executes a two-stage ordering strategy. In the first ordering stage, AHO clusters all the filters according to their popularities and costs factors. In the second stage, for each cluster all the filters are then ordered according to their selectivity. Experiments on both synthetic and real life multimedia streams demonstrate that our AHO method outperforms other simple filtering methods.",

This paper proposes a logic system, called SSML, which can be used to declare, evaluate and verify dynamic security policy. Firstly, we propose the syntax and the semantic of SSML (simple state modifying logic) based on logic programming theory, which shows that an SSML security policy can dynamically insert facts into itself or delete facts from itself. Then, we prove that the query evaluation problem of logic systems based on SSML is undecidable in general, which shows that there is no general algorithm to be able to evaluate all SSML security policies. So we turn to research on its sub-languages, and find two types of SSML security policies with limited syntax-NDel security policies and TDel security policies, and they have decidable evaluation algorithms. We actually give their query evaluation algorithms-OLDT",

        "abstract": "Emerging evidence indicates that microRNAs (miRNAs), a class of small non-coding regulatory RNAs, have important roles in multiple biological processes. To determine the potential contribution of miRNAs to coal workers' pneumoconiosis (CWP), we comprehensively surveyed and identified differentially expressed miRNA profiles in patients with CWP by small RNA sequencing and analysis. Mixed serum samples from the different stages of CWP and the control samples were subjected to deep sequencing by applying next-generation sequencing technology. Samples at different disease stages exhibited inconsistent miRNA expression profiles and differentially expressed miRNA profiles. Generally, these miRNAs were dynamically expressed across the different disease stages and showed various relative expression levels. Some miRNAs (such as miR-18a*, 149, 222 and 671-3p) were consistently up-regulated or down-regulated in the different stages of CWP samples. Most of the aberrantly expressed miRNAs showed a down-regulation trend. Differentially expressed miRNAs were also subjected to pairwise comparison between the different stages. Some miRNAs showed significant inconsistent expression trends across the three stages, although they were not significantly dysregulated based on the control sample. Furthermore, a series of special miRNAs organized into miRNA gene clusters and gene families were also surveyed for aberrant expression (such as mir-200 gene family and mir-222 gene cluster). According to experimentally validated target mRNAs of the aberrantly and abundantly expressed miRNAs, functional enrichment analysis suggests that these miRNAs play important roles in various biological processes, including lung tumorigenesis. In summary, we demonstrated that aberrantly expressed circulating miRNAs showed dynamic expression patterns across diseased samples, which suggests that these miRNAs may have critical roles in the occurrence and development of CWP. In addition, some significantly dysregulated miRNAs may be potential non-invasive diagnosis biomarkers based on further study. \u00a9 2012 Springer Science+Business Media Dordrecht.",

        "abstract": "Standalone microgrids with renewable sources and battery storage play an important role in solving power supply problems in remote areas such as islands. To achieve reliable and economic operations of a standalone microgrid, in addition to the consideration of utilization of renewable resources, the lifetime characteristics of a battery energy storage system also need to be fully investigated. In this paper, in order to realize the economic operation of a recently developed standalone microgrid on Dongfushan Island in China, an optimization model including battery life loss cost, operation and maintenance cost, fuel cost, and environmental cost is established to obtain a set of optimal parameters of operation strategy. Considering the lifetime characteristics of lead-acid batteries, a multiobjective optimization to minimize power generation cost and to maximize the useful life of lead-acid batteries has been achieved via the nondominated sorting genetic algorithm (NSGA-II). The results show that the proposed method can optimize the system operations under different scenarios and help users obtain the optimal operation schemes of the actual microgrid system. \u00a9 2013 IEEE.",

The state-of-the-art methods for CVPs discovery are either computationally expensive or have complicated constraints. In this paper, we formulate CVPs discovery as a graph matching problem, depending on pairwise geometric compatibility between feature correspondences. To efficiently find all CVPs, we propose a novel framework which consists of three components: Preliminary Initialization Optimization (PIO), Guided Expansion (GE) and Post Agglomerative Combination (PAC). PIO gets the initial CVPs and reduces the search space of CVPs discovery, based on the internal homogeneity of CVPs. Then, GE anchors on the initializations and gradually explores them, to find more and more correct correspondences. Finally, to reduce false and miss detection, PAC refines the discovery result in an agglomerative way. Experiments and applications conducted on benchmark datasets demonstrate the effectiveness and efficiency of our method. \u00a9 2013 Elsevier Inc. All rights reserved.",

It is found that more than 900 reactions may occur at the temperature 2000 K within the simulation period with a trajectory output interval of 12.5 ps, and a detailed chemical reaction network was obtained by further analysis of the trajectory using a newly created C++ program. The product profile evolution tendency with temperature observed in the simulation agrees well with what was obtained experimentally in the literature.

Our aim was to determine the accuracy of the iScore in patients with ischemic stroke in China. METHODS - : The iScore was used to predict 30-day mortality rate in 11 656 patients and 1-year mortality rate in 11 051 patients with acute ischemic stroke. These patients were identified from the China National Stroke Registry (CNSR) data set. Model discrimination was quantified by calculating the C statistic. The calibration was assessed using Pearson correlation coefficient. RESULTS - : The 30-day and 1-year mortality rates were 5.4% and 14.3%, respectively. The C statistics were 0.825 (95% confidence interval, 0.807-0.843) for 30-day mortality and 0.822 (95% confidence interval, 0.810-0.833) for 1-year mortality. The plots of observed versus predicted mortality rates showed excellent model calibration in the external validation samples from the CNSR (Pearson correlation coefficient, 0.925 for 30-day and 0.998 for 1-year mortality; both P<0.0001).

In it, a new energy function is defined with a local intensity fitting term in intensity inhomogeneity of the image, and with a global intensity fitting term in intensity homogeneity domain. Weighting factor is chosen to balance these two intensity fitting terms, which can be calculated automatically by local entropy. The level set regularization term is to replace contour curve to find the minimum of the energy function. Particularly, structure tensor is applied to describe the image, which overcomes the disadvantage of image feature without structure information. The experimental results show that our proposed method can segment image efficiently whether it presents intensity inhomogeneity or not and wherever the initial contour is. Moreover, compared with the Chan-Vese model and local binary fitting model, our proposed model not only handles better intensity inhomogeneity, but also is less sensitive to the location of initial contour. \u00a9 2013 World Scientific Publishing Company.",

International Accounting Standard 41 allowed both historical cost and fair value to measure biological assets. More importantly, it introduced fair value measurement as the preferred selection for biological assets. In 2006, China announced CAS5 which required that biological assets should be measured on the basis of historical cost at initial recognition and subsequent reporting period. However, use of fair value was allowed in CAS5 only when biological assets' fair value could be reliably obtained. Based on biological asset's nature, the article discussed arguments on using historical cost or fair value to measure biological. On one hand, using historical cost to measure biological assets was reliable but irrelevant. On the other hand, using fair value to measure biological assets was relevant but unreliable.

With increasing threats against network privacy, anonymous and covert communication technology is becoming more and more important. In this paper, an unobservable rendezvous negotiation protocol is proposed based on P2P architecture, which establishes a covert channel leveraging an existing DHT to hide communicating behaviors and utilizes a tagging mechanism to ensure an indirect identification and mutual authentication.

Most of recent work focuses on dealing with color images or gray scale images with features extracted from text content, annotation or image content. This paper aims at binary text images and proposes a novel clustering method that can be used for automatic image procession in digital library and automatic office. The method is divided into three main steps. Firstly images are preprocessed to denoise, correct orientation and produce coarse classes. Secondly, features are extracted and similar images are grouped into new classes with hierarchical clustering algorithm. At last new classes are combined to the nearest old ones under distance condition. To speed clustering Local Sensitive Hash algorithm is imported for boosting merging procedure. Experiments show that this method is faster and efficient compared with the basic clustering method. \u00a9 Springer-Verlag Berlin Heidelberg 2013.",

        "abstract": "Data leakage committed by malicious insiders proposes a serious challenge for business secrets and intellectual property. Great efforts have been made to detect and mitigate insider threat. Due to the diversity in the motivations, previous work in this field mostly focuses on designing data holder's data distribution and insider tracing algorithms, with little consideration of malicious insiders' leakage strategies. In this paper, the traitors tracing problem is modeled as an incremental refining multi-step process. For each step, a metric is proposed to measure the efficiency of current tracing status. Theoretical and simulating analysis shows that malicious insiders can adopt sophisticated leakage strategies, which makes it difficult to distinguish them from others and leads to more innocent users involved as suspects. Thus it is important for the data holder to figure out the insiders' leakage strategies and adopt proper tracing scheme to improve the refining process. \u00a9 Springer-Verlag Berlin Heidelberg 2013.",

And nowadays, academic researches on CAPTCHA, including designing friendly but secure CAPTCHA systems and breaking existing CAPTCHA systems, are becoming a more and more hot topic. Breaking an existing CAPTCHA system can help to perfect its designs and therefore to improve its security. In this paper, ESBDA, an Ellipse-Shaped Blobs Detection Algorithm, is proposed to detect the ellipse-shaped blobs used in Facebook CAPTCHA scheme, which can be used to break the Facebook CAPTCHA system. The approach is based on detecting the contour of the ellipse-shaped blobs on the basis of erosion and dilation technologies. And the experimental results show that ESBDA can effectively remove the noised ellipse-shaped blobs in the Facebook CPATCHA scheme. \u00a9 Springer-Verlag Berlin Heidelberg 2013.",

In this paper, we defined \u03b4-closureaccording to the complex network theory. Then we tried to design algorithm to attain \u03b4-closure.

By calculating frequency statistics of k-gram strings, we can find out new words as candidates, and then identify new words by their practical application frequency using Twitter's search function.

The ergodicity of logistic chaos sequence and the space extensibility of opposition-based learning were used. Besides, to balance aggregation and divergence, the history information of harmony memory was used to define the updating factor and the evolution factor, which were applied to dynamically adjust the pitch adjustment rate (PAR) and the bandwidth (BW).

To validate the effectiveness of the proposed models, we use the KDDCUP'12 behavior targeting data, issued by the Tecent company in China, as the test bed. The results demonstrate that the proposed models, by incorporating additional social network information, can achieve at least 5% improvement compared to the traditional Poisson regression based model from the CTR lift viewpoint, especially when the historical behavior data is sparse and insufficient. \u00a9 2013 IEEE.",

        "abstract": "MicroRNAs (miRNAs) are crucial negative regulators of gene expression at the post-transcriptional level. Next-generation sequencing technologies have identified a series of miRNA variants (named isomiRs). In this study, paralogous isomiR assemblies (from the miRNA locus) were systematically analyzed based on data acquired from deep sequencing data sets. Evolutionary analysis of paralogous (members in miRNA gene family in a specific species) and orthologues (across different animal species) miRNAs was also performed. The sequence diversity of paralogous isomiRs was found to be similar to the diversity of paralogous and orthologues miRNAs. Additionally, both isomiRs and paralogous/orthologues miRNAs were implicated in 5' and 3' ends (especially 3' ends), nucleotide substitutions, and insertions and deletions. Generally, multiple isomiRs can be produced from a single miRNA locus, but most of them had lower enrichment levels, and only several dominant isomiR sequences were detected. These dominant isomiR groups were always stable, and one of them would be selected as the most abundant miRNA sequence in specific animal species. Some isomiRs might be consistent to miRNA sequences in some species but not the other. Homologous miRNAs were often detected in similar isomiR repertoires, and showed similar expression patterns, while dominant isomiRs showed complex evolutionary patterns from miRNA sequences across the animal kingdom. These results indicate that the phenomenon of multiple isomiRs is not a random event, but rather the result of evolutionary pressures. The existence of multiple isomiRs enables different species to express advantageous sequences in different environments. Thus, dominant sequences emerge in response to functional and evolutionary pressures, allowing an organism to adapt to complex intra- and extra-cellular events. \u00a9 2013 Elsevier B.V.",

        "abstract": "Background and aims: The GPR indices used for predicting root biomass are measures of root radar reflectance. However, root radar reflectance is highly correlated with root water content. The objectives of this study are to assess the impact of root water content on GPR-based root biomass estimation and to develop more reliable approaches to quantify root biomass using GPR. Methods: Four hundred nine roots of five plant species in a sandy area of northern China were examined to determine the general water content range of roots in sandy soils. Two sets of GPR simulation scenarios (including 492 synthesized radargrams in total) were then conducted to compare the changes of root radar signal and the accuracies of root biomass estimation by GPR at different root gravimetric water content levels. In the field, GPR transects were scanned for Ulmus pumila roots buried in sandy soils with three antenna center frequencies (0.5, 0.9, and 2.0 GHz). The performance of two new GPR-based root biomass quantification approaches (one using time interval GPR index and the other using a non-linear regression model) was then tested. Results: All studied roots exhibited a broad range of gravimetric water content (>125 %), with the water contents of most roots ranging from 90 % to 150 %. Both field experiments and forward simulations indicated that 1) waveforms of root radar reflection, radar-reflectance related GPR indices, and root biomass estimation accuracy were all affected by root water content; and 2) using time interval index and establishing a nonlinear regression model of root biomass on GPR indices improved the accuracy of root biomass estimation, decreasing the prediction error (RMSE) by 4 to 30 % under field conditions. Conclusions: The magnitude of GPR indices depends on both root biomass and root water content, and root water content affects root biomass estimation using GPR indices. Using a linear regression model of root biomass on radar-reflectance related GPR index for root biomass estimation would only be feasible for roots with a relative narrow range of water content (e.g., when gravimetric water contents of studied roots vary within 20 %). Appropriate GPR index and regression models should be selected based on the water content range of roots. The new protocol of root biomass quantification by GPR presented in this study improves the accuracy of root biomass estimation. \u00a9 2013 Springer Science+Business Media Dordrecht.",

        "abstract": "An anomaly detection method which can be used for crowd and individual anomalies in videos was proposed. Fast sparse coding algorithm was exploited to generate the dictionary that represents feature samples and reconstruction errors were used as the objective function to discriminate abnormalities. For crowd anomalies, motion estimation and block matching exploited instead of calculating time-consuming optical flow estimation in the entire frame, producing multi-scale histograms of motion and reducing computational complexity effectively. For individual anomalies, the features HNF were extracted, and if the reconstruction error based on sparse representation is beyond the predefined threshold, surprise computation is used for a second detection to judge a false alarm induced by some noise. The difference between different feature descriptors included and not included in the dictionary is computed. If discriminated as a false alarm, the dictionary should be updated to reduce the number of false alarms induced by noise jamming in the subsequent detection process. Experiment results show that the proposed algorithm improves detection rate effectively, reduces computational complexity and can be implemented easily.",

In order to restrain the video distortions caused by data hiding on the premise of low complexity, a new data hiding algorithm based on fast recoding was proposed. The algorithm utilized the prediction information decoded from the original compressed video to re-encode it, and then embedded concealed data into 4\u00d74 blocks inside the I-frames during the new encoding process. Simulation results show that, while keeping the video quality relatively unchanged, the proposed scheme could be used to embed large amounts of concealed data into H. 264/AVC compressed videos without introducing too much bit stream increase. Besides, rather than embedding data in some fixed coefficients, for the imperceptibility and security of the embedded data, a scheme for embedding data into 4\u00d74 blocks by modifying the parity of some selected coefficients' absolute sum was also proposed.",

The pathophysiological mechanisms of PE remain poorly known. Recently, circulating miRNAs are considered as potential useful noninvasive biomarkers. The aim of this study was to identify differentially expressed plasma miRNAs in preeclamptic pregnancies compared with normal pregnancies. Methods. Maternal plasma miRNA expression profiles were detected by SOLiD sequencing. Differential expressions between mPE/sPE and control group were found. Next, four differentially expressed plasma miRNAs were chosen to validate their expression in other large scale samples by real-time PCR. Results. In terms of sequencing results, we identified that 51 miRNAs were differentially expressed. Four differentially expressed plasma miRNAs (miR-141, miR-144, miR-221, and miR-29a) were selected to validate the sequencing results. RT-PCR data confirmed the reliability of sequencing results. The further statistical analysis showed that maternal plasma miR-141 and miR-29a are significantly overexpressed in mPE (P < 0.05). Maternal plasma miR-144 is significantly underexpressed in mPE and sPE (P < 0.05). Conclusions. Results showed that there were differentially expressed maternal plasma miRNAs in patients with preeclampsia. These plasma miRNAs might be used as notable biomarkers for diagnosis of preeclampsia. \u00a9 2013 Hailing Li et al.",

Meanwhile, quality-of-experience (QoE) should be considered and provisioned in the relay scheduling scheme to ensure user experience and comprehensive network performance. In this paper, we studied a QoE provisioning mechanism for a queuing based optimal relay scheduling problem in CRN. We designed a QoE provisioning scheme with multiple optimized goals about higher capacity and lower packet loss probability. The simulation results showed that our mechanism could get a much better performance on packet loss with suboptimum system capacity. And it indicated that our mechanism could guarantee a better user experience through the specific QoS-QoE mapping models.

For this, first, we discuss its optimal solution and then we design two kinds of efficient heuristic algorithms. Numerical results reveal that our heuristic channel allocation algorithm with negotiation can achieve near-optimal throughput well satisfying the QoS requirements with simplicity. \u00a9 2013 NICT.",

        "abstract": "Background and aims: It remains unclear how the limiting factors (e.g., root size, root water content, spacing between roots, and soil water content) affect root investigation using ground penetrating radar (GPR). The objective of this study is to develop a theoretical forward simulation protocol of synthesizing root's GPR signal and test the feasibility of our proposed simulation protocol in evaluating the impacts of limiting factors on GPR-based root detection and quantification. Methods: The proposed forward simulation protocol was developed by integrating several existing numerical models, such as the Root Composition Model, the Root Dielectric Constant Model, the Root Electrical Conductivity Model, the Soil Dielectric Constant Model, the Soil Electrical Conductivity Model, and a newly-established model (Root Length-Biomass Model). Resolution and GPR index obtained from both field collected radargrams and corresponding simulations were compared to validate the accuracy of simulation. Results: Simulated radargrams exhibit similar resolution with that of the in situ collected. The same trends of root radar signals against different levels of root size, root water content, interval between roots, root depth, and antenna frequency were observed on both in situ radargrams and simulated radargrams. Strong correlations (correlation coefficients ranging from 0.87 to 0.96) were found between GPR indices extracted from the simulated data and those from the field collected data. Conclusions: Our proposed forward simulation is effective for assessing the impacts of limiting factors on root detection and quantification using GPR. This forward simulation protocol can be used to provide guidance for in situ GPR root investigation and can predict the accuracy of GPR-based root quantification under site-specific conditions. \u00a9 2013 Springer Science+Business Media Dordrecht.",

        "abstract": "In this paper, we study a new problem on social network influence maximization. The problem is defined as, given a target user w, finding the top-k most influential nodes for the user. Different from existing influence maximization works which aim to find a small subset of nodes to maximize the spread of influence over the entire network (i.e., global optima), our problem aims to find a small subset of nodes which can maximize the influence spread to a given target user (i.e., local optima). The solution is critical for personalized services on social networks, where fully understanding of each specific user is essential. Although some global influence maximization models can be narrowed down as the solution, these methods often bias to the target node itself. To this end, in this paper we present a local influence maximization solution. We first provide a random function, with low variance guarantee, to randomly simulate the objective function of local influence maximization. Then, we present efficient algorithms with approximation guarantee. For online social network applications, we also present a scalable approximate algorithm by exploring the local cascade structure of the target user. We test the proposed algorithms on several real-world social networks. Experimental results validate the performance of the proposed algorithms. Copyright 2013 ACM.",

        "abstract": "On the Internet, service accessibility is directly related to the reachability of entry points to its service infrastructure. There exists a main challenge in the distribution of these entry points: how to disseminate them widely while avoid the adversary from enumerating them. This paper presents the model of distribution problem under enumeration attacks. A few factors that can influence service accessibility are also presented based on a probabilistic analysis of the model. To improve accessibility, we propose dynamic distribution where the distribution parameter (number of resources assigned to each user) can be adjusted dynamically according to the confrontation situation. Experiments over simulation validate the effectiveness of this idea in accessibility improvement. \u00a9 2013 The Authors. Published by Elsevier B.V.",

        "abstract": "It is well known that data loss caused by data stolen Trojans is huge as it could upload privacy or secret data to hackers who controls it remotely. Most of current security tools monitor Trojans by scanning the signature code that is distinguished from normal software. However, this method can only recognize known Trojan except up-to-date malicious software that has unknown signature code. Some other security tools requiring preinstalled on hosts detects Trojans by program behaviors. This paper proposes a novel medel to detect data stolen Trojans based on their network behaviors. It consists of three detectors: 1) keep-alive detector detects keep-alive packets or connections; 2) master-slave-connection detector tries to find master and slave connections and 3) mistake detector analyses the rate of download vs. upload and connection time for different protocol. The experiments show that this method is efficient in recognizing data stolenTrojans. This protyped system proves the possibility of detection Trojans from network. \u00a9 2013 The Authors.

As applications, 16 specimens for 4 different concrete mixes are generated and calculated. Results show that the numerical model can be used for revealing common failure modes and mechanisms. the increase of aggregate volume fraction can improve concrete ductility, while at the same time, lower its strength, which coincides with existing experimental results. The model provides a new approach for numerically modeling the failure process of quasi-brittle materials.

Recently, Tor nodes from Tor families (referred to as family nodes) have played an increasingly important role and caused significant influence on the Tor network. However, existing research about Tor mostly focuses on the entire Tor network without much consideration about the difference between family nodes and the others. In order to analyze family nodes' contribution to the entire Tor network as well as their influence, this paper distinguishes family nodes from the others, and gives an empirical analysis of family nodes based on the live Tor network data of 3 years. Results show that, family nodes compose a small but full functional subset of Tor nodes; and compared with the other Tor nodes, they can provide relatively stable and high-performance service to Tor users. Furthermore, family nodes naturally form a hot area in the Tor network, relaying increasingly high-density traffic through a small number of nodes. Compared with random node targets, selective attacks focusing on family nodes can cause serious availability downgrade of the Tor network with much lower cost. \u00a9 2013 IEEE.",

        "abstract": "DC bus voltage control is an important task in the control of a dc microgrid or hybrid ac/dc microgrid system. To improve the dc bus voltage control dynamics, traditional approaches are mainly based on feeding forward the load or source power. However, in the microgrid system with distributed dc sources and loads, the traditional feedforward based methods need remote measurement or communications. In this paper, a nonlinear disturbance observer (NDO) based dc bus voltage control is proposed, which does not need the remote measurement or communication with a true plug-and-play feature. Based on this observer, a novel dc bus voltage control scheme with pulse-width-modulation (PWM) dead-time compensation is developed. The proposed method can suppress the transient fluctuations of dc bus voltage, and improve the power quality in such a hybrid microgrid system. The performance of the presented control strategy has been successfully verified in a 30 kVA dc subgrid including battery energy storage system, photovoltaic power generation system and a dc load. \u00a9 2013 IEEE.",

In this paper, we mainly focus on recovering super-resolution version given only one single low-resolution (LR) image. The proposed method is combined with the example-based algorithm, which also exploits the relationship between the low image patches and the high image patches. Firstly, the proposed method applies guided filter, the first-order and second-order derivatives to extract multiple features from LR images, which superior to using only one feature space. Then, the effective dictionary is constructed by a novel algorithm called Relaxation K-SVD (R-KSVD). R-KSVD relaxes the constraints of Orthogonal Matching Pursuit method (R-OMP) in training dictionary for K-SVD algorithm. Finally, a new approach is presented to estimating better HR residual image in the Back Projection.

The transforming rules are learned from corresponding latent state sequence of multiple time series based on Markov chain character. The reusable semantics learned by CfSLF can be fed into various analysis tools, such as prediction or anomaly detection. Moreover, we present two algorithms based on the semantics, which can later be applied to next-n step prediction and anomaly detection.

Based on the success of low-rank matrix recovery which has been applied to statistical learning, computer vision and signal processing, this paper presents a novel low-rank matrix recovery algorithm with discriminant regularization. Standard low-rank matrix recovery algorithm decomposes the original dataset into a set of representative basis with a corresponding sparse error for modeling the raw data. Motivated by the Fisher criterion, the proposed method executes low-rank matrix recovery in a supervised manner, i.e., taking the with-class scatter and between-class scatter into account when the whole label information is available. The paper shows that the formulated model can be solved by the augmented Lagrange multipliers, and provide additional discriminating ability to the standard low-rank models for improved performance. The representative bases learned by the proposed method are encouraged to be structural coherence within the same class, and as independent as possible between classes. Numerical simulations on face recognition tasks demonstrate that the proposed algorithm is competitive with the state-of-the-art alternatives. \u00a9 Springer-Verlag 2013.",

        "abstract": "Influence maximization, defined as finding a small subset of nodes that maximizes spread of influence in social networks, is NP-hard under both Linear Threshold (LT) and Independent Cascade (IC) models, where a line of greedy/heuristic algorithms have been proposed. The simple greedy algorithm [14] achieves an approximation ratio of 1-1/e. The advanced CELF algorithm [16], by exploiting the sub modular property of the spread function, runs 700 times faster than the simple greedy algorithm on average. However, CELF is still inefficient [4], as the first iteration calls for N times of spread estimations (N is the number of nodes in networks), which is computationally expensive especially for large networks. To this end, in this paper we derive an upper bound function for the spread function. The bound can be used to reduce the number of Monte-Carlo simulation calls in greedy algorithms, especially in the first iteration of initialization. Based on the upper bound, we propose an efficient Upper Bound based Lazy Forward algorithm (UBLF in short), by incorporating the bound into the CELF algorithm. We test and compare our algorithm with prior algorithms on real-world data sets. Experimental results demonstrate that UBLF, compared with CELF, reduces more than 95% Monte-Carlo simulations and achieves at least 2-5 times speed-raising when the seed set is small. \u00a9 2013 IEEE.",

        "abstract": "As crucial negative regulatory molecules, small non-coding RNAs, microRNAs (miRNAs), have been widely studied, especially for their functions and evolutions. Multiple miRNA variants, termed as isomiRs, are recently detected and identified from a given miRNA locus due to alterative and imprecise cleavage of Drosha and Dicer. Compared to the canonical miRNA sequence, these isomiRs may be found various 5' and/or 3' ends (various 3' ends are more popular), 3' additional non-template nucleotides, 5' and seed modification events. Similarly, miRNA sequences in different animal species also show diversity as well as species specificity. The miRNA sequences in different animal species may be involved in different length distributions, 5' and/or 3' ends, transition/transversion and insertion/deletion. From a given miRNA locus, internal multiple isomiRs and various miRNA sequences across species are quite similar and have close relationships. Indeed, they also implicate potential functional and evolutionary relationships. By applying high-throughput sequencing technique, multiple isomiRs from a given miRNA locus can be identified with different sequence counts, length distributions and various expression patterns, although isomiR repertoire and their expression patterns always are stable across different tissues, samples and even animal species. Most isomiRs were 3' isomiRs which had the same seed sequences, while 5' isomiRs were found to have new seed sequences via the phenomenon of \"seed shifting\". Many miRNAs were detected a set of isomiRs, in which 1-3 were abundant isomiRs characterized by a narrow length distribution (20-23 nt) due to dominant cleavage. Indeed, specific miRNA sequences have been identified in specific animal species through classical experimental validation. The annotated miRNA sequence is always derived from the most abundantly expressed isomiR, which is prone to be detected by traditional detection. Therefore, we speculate that the most dominant isomiR is not randomly selected, but is strictly regulated by complex regulatory network from selection and evolutionary pressures. Various miRNA sequences can unveil dynamic evolutionary processes across different animal species (cross-species) and across different miRNAs (within species), especially simultaneously involved in the diversity of pre-miRNA and pri-miRNA sequences. Furthermore, more miRNA* sequences, ever as passenger strands of miRNA sequences, are identified as active and functional miRNA sequences. These potential functional miRNA* sequences and potential more functional isomiRs (such as 5' isomiRs with novel seed sequences by changing 5' ends) will complicate miRNA-mRNA and miRNA-miRNA interaction, and enrich coding-non-coding RNA regulatory network. \u00a9 2013 Nova Science Publishers, Inc.

Driven by economic interests and the game between countries reflected by growing cyberspace confrontations, evasive network attacks on information infrastructures with high-tech, high concealment and long-term sustainability become severe threats to national security. In this paper, we propose a novel two-phased method for the detection of evasive network attacks which exploit or pretend to be common legal encryption services in order to escape security inspection. Malicious communications which camouflage themselves as legal encryption application are identified in the SSL1 session structure verification phase firstly, and then by server-side X.509 certificate based anomaly detection, suspicious attack behaviors are further distinguished effectively. Experiment results show that our method is very useful for detecting the network activities of certain unknown threats or new malwares. Besides, the proposed method can be applied to other similar services easily.",

        "abstract": "Aiming at the demand on fast and real time map matching for massive floating car, this paper proposed a local map matching algorithm which combined online map matching with offline calculation. The Offline calculation firstly build two levels of grids for vector road network, and then combined similarity could be pre-calculated offline which takes both the distance from center of each cell to every candidate matching road segment or node and traffic direction of every candidate matching road segment into account. According to the value of the difference between the maximal combined similarity and the second largest combined similarity, the related road segment or road node whose combined similarity clearly dominated could be stored in advance as attribute value of the cell in second level grid. When online map matching is implemented for every real time GPS point, the cell in the second level of grid where the GPS point fall within could be firstly instantly got, and then measure of path accessibility from previous GPS point to current GPS point could be quickly determined by means of two-way forward and backward method, and then final matching result of real time GPS point that is the attribute value stored in advance could be instantly obtained according to the value of path accessibility. Experiments on massive floating car in Shenzhen city show that the matching speed of this method is twice as fast as the matching speed of local map matching method, and it only occupied about 8 M storage space on storing two level of grids and its attribute values which could be read into memory once, and it took about 32 hours to finish offline calculation for the whole Shenzhen road network, however, once offline calculation is finished, it was able to provide a long history service to online map match.",

        "abstract": "Attacks from insiders usually disguise themselves as normal behaviors, which causes the uncertainty of the results based on anomaly detection models. Attack graph model is frequently used to describe the causal relationships among the steps in multiple attack progress, yet the uncertainty of events represented by the current observations is rarely considered in calculating the optimal security hardening measures, neither the impact of the probability of the attack success is depicted from the angle of probability after the implementation of the security measures. In this paper, we discuss completly three kinds of uncertainty in attack graph, and add the security hardening nodes into the probability attack graph model based on previous studies, and clarify the influence of the transition probability by security hardening measures. For the first time we put forward measures probability attack graph (MPAG) and apply it to the calculation of the optimal security hardening measures for insider threat risk analysis and mitigation. Based on this model, we prove that the calculation for optimal security hardening measures is an NP-hard problem, furthermore, we propose a greedy algorithm to calculate dynamically the approximate optimal security hardening measures set. Finally the paper proves in real network environment that the algorithm can calculate the approximate optimal security hardening measures set under certain cost constraints, given current observables sequence and the responding confidence probability.",

Ssh10b, a member of the Sac10b family from the hyperthermophilic crenarchaeon Sulfolobus shibatae, binds to RNA in vivo. Here we show that binding by Ssh10b destabilizes RNA secondary structure. Structural analysis of Ssh10b in complex with a 25-bp RNA duplex containing local distortions reveals that Ssh10b binds the two RNA strands symmetrically as a tetramer with each dimer bound asymmetrically to a single RNA strand. Amino acid residues involved in double-stranded RNA binding are similar, but non-identical, to those in dsDNA binding. The dimer-dimer interaction mediated by the intermolecular \u03b2-sheet appears to facilitate the destabilization of base pairing in the secondary structure of RNA. Our results suggest that proteins of the Sac10b family may play important roles in RNA transactions requiring destabilization of RNA secondary structure in Sulfolobus. \u00a9 2014 by The American Society for Biochemistry and Molecular Biology, Inc.",

        "abstract": "Increasing evidence suggests that non-coding RNAs have multiple important roles in transcriptional regulation, and also contribute to the expansion of genome complexity. Here, we attempted to perform an integrative analysis of miRNA-lncRNA in mammals to reveal their potential evolutionary relationships in transcriptional regulation network. The lncRNA of H19 gene includes an internal small non-coding RNA, miR-675. The H19 gene was conserved as well as the neighbor Igf2 coding gene and internal miR-675 gene, although they were involved in various location distributions and phylogenetic relationships. Both miR-675-5p/3p have been reported as potential negative regulatory molecules, but the canonical miRNA was more conserved than the passenger strand. These results implicated that the imprinted coding and non-coding gene cluster indicated similar evolutionary patterns. The lncRNA and internal miRNAs may have versatile roles in multiple biological processes, including in tumorigenesis as potential ncRNA regulatory molecules. The phylogenetical conservation of the imprinted cluster may be also derived from the functional implications and evolutionary pressures. The study will enrich the study of potential crosstalk of miRNA-lncRNA and mRNA-ncRNA. \u00a9 2013 Springer Science+Business Media Dordrecht.",

While previous works on semantic relation automatic acquisition relied on annotated text corpus, it is still unclear how to develop more generic methods to meet the needs of identifying related event pairs and extracting event-arguments (especially the predicate, subject and object). Motivated by this limitation, we develop a three-phased approach that acquires causality from the Web text. First, we use explicit connective markers (such as \"because\") as linguistic cues to discover causal related events. Next, we extract the event-arguments based on local dependency parse trees of event expressions. At the last step, we propose a statistical model to measure the potential causal relations. The results of our empirical evaluations on a large-scale Web text corpus show that (a) the use of local dependency tree extensively improves both the accuracy and recall of event-arguments extraction task, and (b) our measure improves the traditional PMI method. \u00a9 The Authors.

        "abstract": "In this paper, we present a new approach to detect global hot events and local hot events. Unlike previous event detection algorithms which do not distinguish between global events and local events, we believe it is important that we make that distinction as certain events can only be meaningful if they are placed in specific context while other events may arouse the interests of general users. The main contribution of this paper is that we've customized hot events detection by employing local community detection mechanisms and established a very clear concept for global hot events and local hot events. We present in this paper a multi-layer event detection algorithm which constructs a four-stage event detection procedure that produces a relatively comprehensive description of events relevant to the unique makeup and different interest of microblog users. Both the global hot events and local hot events we gathered are represented by a key tweet which contains sufficient information to depict a complete event. As a result of our algorithm's ability to precisely describe events which outperforms existing event detection algorithms, it is now possible for people to better understand public sentiment towards hot issues on microblogs. Experiments have shown that our multi-layer hot event detection algorithm can produce promising results in mining the interests of different communities, generating relevant event clusters and presenting meaningful events to community users. The most allround evaluation indicator F-value, which takes both precision and recall rate into account, has demonstrated that our algorithm outperforms the other three traditional approaches in detecting hot events. \u00a9 The Authors.

While influence maximization has been extensively studied as the fundamental solution, it neglects the reality that a user may purchase a product/service repeatedly, incurring cumulative sales of the product/service. In this paper, we explore a new problem of cumulative influence maximization that brings the influence maximization a step closer to real-world viral marketing applications. In our problem setting, repeated activation exists and we aim to find a set of initial users, through which the maximal cumulative influence can be stimulated in a given time period. To describe the repeated activation behavior, we adopt the voter model to reflect the variation of activations over time. Under the voter model, we formulate the maximization problem and present an effective algorithm. We test and compare our method with heuristic algorithms on real-world data sets.

        "abstract": "Social networks have greatly amplified spread of information across different communities. However, we recently observe that various malicious information, such as computer virus and rumors, are broadly spread via social networks. To restrict these malicious information, it is critical to develop effective method to discover the diffusion source nodes in social networks. Many pioneer works have explored the source node identification problem, but they all based on an ideal assumption that there is only a single source node, neglecting the fact that malicious information are often diffused from multiple sources to intentionally avoid network audit. In this paper, we present a multi-source locating method based on a given snapshot of partially and sparsely observed infected nodes in the network. Specifically, we first present a reverse propagation method to detect recovered and unobserved infected nodes in the network, and then we use community cluster algorithms to change the multi-source locating problem into a bunch of single source locating problems. At the last step, we identify the nodes having the largest likelihood estimations as the source node on the infected clusters. Experiments on three different types of complex networks show the performance of the proposed method. \u00a9 The Authors. Published by Elsevier B.V.",

In this report, we show that an RFC complex from the hyperthermophilic archaea of the genus Sulfolobus physically interacts with DNA polymerase B1 (PolB1) and enhances both the polymerase and 3'-5' exonuclease activities of PolB1 in an ATP-independent manner. Stimulation of the PolB1 activity by RFC is independent of the ability of RFC to bind DNA but is consistent with the ability of RFC to facilitate DNA binding by PolB1 through protein-protein interaction. These results suggest that Sulfolobus RFC may play a role in recruiting DNA polymerase for efficient primer extension, in addition to clamp loading, during DNA replication. \u00a9 2014, American Society for Microbiology.",

        "abstract": "Introduction: In a recent paper, Tanikawa et al. Plant Soil 373:317-327, (2013) reported a considerable impact of root orientation on the accuracy of root detection and root diameter estimation by ground-penetrating radar (GPR).Methods: In Tanikawa et al. Plant Soil 373:317-327, (2013), buried root samples in a sand box were scanned from multiple cross angles between root orientation and GPR transecting line under controlled conditions. Changes in radar waveform parameter of roots to different cross angles were investigated.Results: Tanikawa et al. Plant Soil 373:317-327, (2013) clarified that 1) the variation in amplitude area (a signal strength related waveform parameter) to different cross angles fitted a sinusoidal waveform; and 2) the impact of root orientation on root diameter estimation by GPR could be mathematically corrected by applying a grid transect survey. However, we found that the quantitative relationship established in Tanikawa et al. Plant Soil 373:317-327, (2013) between amplitude area and cross angle was incorrect, and the application of a grid transect survey still underestimated root diameter.Conclusion: The change in amplitude area to cross angle between transecting line and root orientation fits a sinusoidal waveform but different to that reported in Tanikawa et al. Plant Soil 373:317-327, (2013). The polarization of GPR wave may explain such sinusoidal variation in amplitude area to cross angle. The effect of root orientation on GPR-based root diameter estimation remains to be calibrated. \u00a9 2014 Springer International Publishing Switzerland.",

        "abstract": "Collaborative filter has been widely and successfully applied in recommendation system. It typically associates a user with a group of like-minded users based on their preferences over all the items, and recommends to the user those items enjoyed by others in the group. Some previous studies have explored that there exist many user-item subgroups each consisting of a subset of items and a group of like-minded users on these items and subgroup analysis can get better accuracy. While, we find that geographical information of user have impacts on user group preference for items. Hence, In this paper, we propose a Bayesian generative model to describe the generative process of user-item subgroup preference under considering users' geographical information. Experimental results show the superiority of the proposed model. \u00a9 The Authors. Published by Elsevier B.V.",

        "abstract": "Background: Monoclonal antibody (mAb)-based targeted therapy is one of the most promising strategies to cure cancers. MAb ZCH-2B8a (2B8a) was a novel antibody generated in our laboratory, which presented potential to be a therapeutic agent for hematologic malignancies. Methods: We investigated the reactivity profile of 2B8a mAb, identified the targeting antigen by proteomic and genetic approaches and evaluated its potential to exert tumor cell killing. Results: 2B8a antigen was strictly expressed on lymph tissues and hematopoietic cells (mainly leukocytes), and was highly expressed on B-lineage leukemia cell lines and acute lymphoblastic leukemia (ALL) cells from patients. 2B8a antibody was quickly internalized into the target cells once binding to the antigen, but was capable of killing tumor cells through complement dependent cytotoxicity. To identify the 2B8a antigen, the proteins of Raji cells were immunoprecipitated with 2B8a antibody and analyzed by mass spectrometry, which indicated that coronin-1a was a potential candidate. Then, coronin-1a gene was cloned from Raji cells, inserted into plasmid pcDNA3.1 (+), and transfected into CHO cells. The intracellular 2B8a antigen level was significantly increased in the coronin-1a transfectant cell line. Conclusion: 2B8a mAb is a novel antibody targeting coronin-1a, which has the potential to be a therapeutic agent for B-lineage malignancies. \u00a9 2014 Informa UK Ltd.

We use k-means method to capture several cluster centroids for each class, and then choose the high frequency words in centroids as the text features for categorization. The words extracted by k-means not only can represent each class clustering well, but also own high quality for semantic expression.

Its performance directly affects the precision and reliability of Micro Total Analysis Systems (\u03bcTAS), and it also plays a key role in the targeting transport of trace substances. The single and double chamber valveless micropumps with saw-tooth microchannel were designed. The saw-tooth diffuser/nozzle pipe was fabricated on chrome glass substrate using MEMS technology and the pump diaphragm was manufactured by PMMA material. The piezoelectric bimorph with cantilever beam was adopted as driving pump actuator and PDMS material as pump diaphragm. The valveless micropumps for both single and double chambers were formed with different saw-tooth structure parameters. The flow rate increased about 25 % when the sidewall of microchannel changed from smooth to saw-tooth, and with the driving voltage increasing, the positive and negative flow difference of saw-tooth diffuser/nozzle pipe increased significantly, so does the micro pump flow rate. The best diffused angle ? was determined by the microchannel length L of sawtooth diffuser/nozzle pipe, and the micro pump operated with its maximum flow rate only when the length-width ratio A reached the best value. The flow rate of a saw-tooth diffuser/nozzle valveless micropump with parallel double chambers increased approximately 30 % than that of a single chamber. \u00a9 (2014) Trans Tech Publications, Switzerland.",

Its 3D skeleton data has less data and retains the key information, and the MCRF model has the advantage of being able to combine more features and utilizing adaptive contextual information. First, human activity was divided into global activity, arm activity, and leg activity. Several feature subsets were formed through more feature extraction. Then, CRF models were used on each feature subset to generate CRF units. Finally, all the CRF units were combined to produce the MCRF model which was utilized to recognize human activity.

        "abstract": "miRNA variants (termed isomiRs) have been reported as potential functional molecules that may affect miRNA stability or target selection. The aims of the present study were to comprehensively survey and characterize non-template nucleotides (NTNs) and isomiR repertoires in miRNAs. Over 50\u00a0% of the NTNs were located in the 3\u2032 ends (also termed 3\u2032 additions), followed by the 5\u2032 ends and adjacent positions to 5\u2032 and 3\u2032 ends. The similar distributions of NTNs and isomiR repertoires might be detected between homologous or clustered miRNAs. miRNA might be stably expressed based on the typical analysis, but its isomiRs might be strongly up- or down-regulated. IsomiRs with novel seed sequences were mainly derived from \u201cseed shifting\u201d events in 5\u2032 isomiRs, NTNs in 5\u2032 ends or in seed sequences. IsomiRs from a miRNA locus or homologous miRNA loci maybe have the same seed sequences, but they would have various enrichment levels and 3\u2032 ends. Interestingly, isomiR species with novel seed sequences via NTNs in the seed region were always stably expressed. These novel seed sequences could lead to novel functional roles through driving the potential novel target mRNAs. Integrated predicted target mRNAs and further microarray validation showed that these isomiRs have versatile biological roles. Collectively, multiple isomiR products and miRNA maturation processes provide opportunities to perform versatile roles in the regulatory network, which further enriches and complicates the regulation of biological processes.",

        "abstract": "This paper experimentally demonstrates a saw-tooth diffuser/nozzle valveless micropump. The saw-tooth diffuser/nozzle pipe is fabricated on chrome glass substrate using MEMS technology. A PMMA material is used to manufacture the pump chamber. The vibration of piezoelectric cantilever drives PDMS diagram to do reciprocating motion. It has been shown that the steady flow rate of the saw-tooth diffuser/nozzle pipe increase a 25-percent over the smooth one. A good agreement between the experiments and theoretical analysis based on finite element method is obtained. The best diffused angle \u03bb was determined by the microchannel length L of saw-tooth diffuser/nozzle pipe, and the micro pump operates with its maximum flow rate as soon as the length-width ratio A reached the optimized value. We are believed to be the first to propose the concept of wedge seal method, which can improve the performance of the seal method. \u00a9 2014 IEEE.",

Firstly, two operational modes are presented according to the operation objectives and operation characteristics of the microgrid. Secondly, a real time energy management strategy for the two modes is presented based on the super short-term wind speed prediction, which is on account of the genetic algorithm-neural network (GA-BP) prediction model. In accordance with the results of the super short-term wind speed prediction, the operational mode of the microgrid system can be confirmed, and the power limited order for the wind generation can be ensured, which can reduce the running time of diesel generator on the basis of the guarantee of the system stable operation. Lastly, using the analog-digital simulation platform built based on real time digital simulator (RTDS), a case is done to verify the control strategy of the two operational modes, which proved the validity and feasibility of the control strategy.",

        "abstract": "PE pyrolysis is considered as an important process for converting plastic solid waste into fuel or other valuable chemicals to alleviate the environmental burdens. A computational approach can be of help for fully understanding the mechanisms and reaction pathways during PE pyrolysis in various industrial applications. In this paper, ReaxFF molecular dynamics was for the first time applied in simulating the pyrolysis of a High Density Polyethylene (HDPE) model system with 7216 atoms. Detailed reaction mechanisms and generation pathways of primary gas molecules were obtained by further analysis of the trajectories within a total of 250 ps simulation in NVT ensemble at 2000-3000 K using a newly created program, VARMD. The product profile and primary gas products evolution tendencies with temperature agree reasonably with the observations in Py-GC/MS experiments and literature data. The overall kinetics of \u223c C31 were analyzed and used to predict the reaction time for 90% weight loss of HDPE thermolysis that falls in around the reported time observed experimentally in the literatures. The reaction mechanisms based on the detailed reactions from the simulation trajectories are in broad agreement with what reported in literatures. The work presented here validates that ReaxFF MD is a promising method to help building a systematic understanding of the detailed chemical reactions in pyrolytic process for polymers. \u00a9 2014 Elsevier Ltd.

The present work reports an integrative analysis of miRNA-mRNA and miRNA-miRNA interactions and their regulatory patterns using high-throughput miRNA and mRNA datasets. Aberrantly expressed miRNA and mRNA profiles were obtained based on fold change analysis, and qRT-PCR was used for further validation of deregulated miRNAs. miRNAs and target mRNAs were found to show various expression patterns. miRNA-miRNA interactions and clustered/homologous miRNAs were also found to contribute to the flexible and selective regulatory network. Interacting miRNAs (e.g., miRNA-103a and miR-103b) showed more pronounced differences in expression, which suggests the potential \"restricted interaction\" in the miRNA world. miRNAs from the same gene clusters (e.g., miR-23b gene cluster) or gene families (e.g., miR-10 gene family) always showed the same types of deregulation patterns, although they sometimes differed in expression levels. These clustered and homologous miRNAs may have close functional relationships, which may indicate collaborative interactions between miRNAs. The integrative analysis of miRNA-mRNA based on biological characteristics of miRNA will further enrich miRNA study. \u00a9 2014 Li Guo et al.",

        "abstract": "Many microRNAs (miRNAs) are clustered on chromosomes and co-transcribed as polycistronic transcripts. Here, an integrated evolutionary analysis of human miRNA gene clusters and families was performed. Generally, miRNA gene clusters include 2-8 members, but some larger clusters have been found to have more members (over 40 miRNAs). 62.22% of them have been shown to be involved in homologous miRNA genes, including multicopy pre-miRNAs and sense/antisense homologous miRNAs. Multicopy pre-miRNAs can enrich the distribution and relationship between miRNA clusters and families. An miRNA family may be located in one or more clusters, and a cluster may be involved in one or more families. Members of different families have been shown to be prone to appear in clusters, and vice versa. Reconstructed phylogenetic trees and networks may indicate potential evolutionary relationships, which also indicate duplication history in specific related gene clusters and families. Related miRNA families are always found to share common target mRNAs and biological pathways. Some clusters containing non-homologous miRNAs also tend to be clustered together as well as homologous miRNAs. In the present work, it is shown that homologous miRNAs are prone to appear in clusters based on functional and evolutionary pressures. The phenomenon of miRNA clusters containing homologous or genetic relationships is quite common. The integrative evolutionary analysis will provide more potential evolutionary and functional relationships between homologous and clustered miRNAs. \u00a9 2013 Elsevier B.V.",

The compositions of miRNA gene clusters and families are not random, and clustered and homologous miRNAs may have close relationships with overlapped miRNA species. Members in the miRNA group always had various expression levels, and even some showed larger expression divergence. Despite the dynamic expression as well as individual difference, these miRNAs always indicated consistent or similar deregulation patterns. The consistent deregulation expression may contribute to dynamic and coordinated interaction between different miRNAs in regulatory network. Further, we found that those clustered or homologous miRNAs that were also identified as sense and antisense miRNAs showed larger expression divergence. miRNA gene clusters and families indicated important biological roles, and the specific distribution and expression further enrich and ensure the flexible and robust regulatory network. \u00a9 2014 Li Guo et al.",

        "abstract": "Accumulating evidences suggest that microRNA (miRNA) is not a single sequence, but a cluster of isomiR sequences with various 5\u2019/3\u2019 ends and length distributions. The typical analysis always focuses on the annotated canonical miRNAs, although the multiple isomiRs have been reported as potential regulatory molecules with versatile biological roles. Herein, we develop an approach to analyze miRNA at the miRNA/isomiR levels. Firstly, isomiR expression profiles are estimated based on miRNA locus. Secondly, isomiR expression profiles are compared between clustered/homologous miRNAs. Thirdly, isomiR expression profiles are assessed at the isomiR level. Those isomiRs with the same \u201cseed sequences\u201d are classified as a special miRNA class. Finally, isomiR:mRNA interaction is predicted at the isomiR level, and target mRNAs and functional enrichment analysis can be performed to explore biological roles. Furthermore, the approach is applied to analyze miRNA at the miRNA/isomiR levels using small RNA sequencing datasets of tumor and normal cells. The analysis at the miRNA/isomiR levels will track miRNA maturation process and biological genesis, and provide more points to explore versatile biological roles of the small non-coding RNAs.",

One of the major challenges is keeping underlying infrastructure in reasonably low power states and achieving service-level objectives (SLOs) of upper applications as well. Existing solutions, however, cannot effectively tackle this problem for virtualized environments. In this paper, we propose an automated power control solution for such scenarios in hope of making some progress. The major advantage of our solution is being able to precisely control the CPU frequency levels of a physical environment and the CPU power allocations among virtual machines with respect to the SLOs of multiple applications. Based on control theory and online model estimation, our solution can adapt to the variations of application power demands. Additionally, our solution can simultaneously manage the CPU power control for all virtual machines according to their dependencies at either the application-level or the infrastructure-level. The experimental evaluation demonstrates that our solution outperforms three state-of-the-art methods in terms of achieving the application SLOs with low infrastructure power consumption.",

However, smaller temporal reconstruction times can not effectively remove motion blur and motion aliasing, while larger times will lead to serious temporal-ringing and the wrong location of a moving object in process of temporal reconstruction. This paper explores how to select an appropriate temporal construction times in the temporal reconstruction. In general, only the number of input video sequences is considered in deciding temporal reconstruction times of video-to-video super-resolution reconstruction. In fact, temporal reconstruction times are also associated with redundant temporal information provided by each input low-temporal resolution video sequence. So, a novel method to select an appropriate temporal reconstruction times is proposed by analyzing the exposure-time and location relation of aligned low resolution input video sequences. From theoretical discussion and experimental results, the proposed method is validated to be effective and efficient.",

        "abstract": "Agents inhibiting microglial activation are attracting attention as candidate drugs for neuroprotection in neurodegenerative diseases. Recently, researchers have focused on the immunosuppression induced by rifampicin. Our previous study showed that rifampicin inhibits the production of lipopolysaccharide (LPS)-induced pro-inflammatory mediators and improves neuron survival in inflammation; however, the mechanism through which rifampicin inhibits microglial inflammation and its neuroprotective effects are not completely understood. In this study, we examined the effects of rifampicin on morphological changes induced by LPS in murine microglial BV2 cells. Then we investigated, in BV2 microglia, the effects of rifampicin on two signaling pathway componentss stimulated by LPS, the Toll-like receptor-4 (TLR-4) and the nuclear factor-\u03baB (NF-\u03baB). In addition, we co-cultured BV2 microglia and neurons to observe the indirect neuroprotective effects of rifampicin. Rifampicin inhibited LPS-stimulated expression of the TLR-4 gene. When neurons were co-cultured with LPS-stimulated BV2 microglia, pre-treatment with rifampicin increased neuronal viability and reduced the number of apoptotic cells. Taken together, these findings suggest that rifampicin, with its anti-inflammatory properties, may be a promising agent for the treatment of neurodegenerative diseases.",

Each component has an increasing failure rate and is subjected to external impacts that can occur with fixed frequency. In order to increase the system availability, three measures can be taken: 1. Increase of the components replacement frequency; 2. Overarching protection of the system; 3. Individual component protection. The external impact must penetrate both the overarching protection and the individual component protection in order to destroy a component. The optimal resource allocation strategy which minimizes the total cost of maintenance, protection and damage caused by unsupplied demand is studied. The proposed approach is based on a universal generating function technique and a genetic algorithm. \u00a9 ICAQM 2014.",

        "abstract": "ReaxFF MD (Reactive Force Field Molecular Dynamics) is a promising method for investigating complex chemical reactions in relatively larger scale molecular systems. The existing analysis tools for ReaxFF MD lack the capability of capturing chemical reactions directly by analyzing the simulation trajectory, which is critical in exploring reaction mechanisms. This paper presents the algorithms, implementation strategies, features, and applications of VARxMD, a tool for Visualization and Analysis of Reactive Molecular Dynamics. VARxMD is dedicated to detailed chemical reaction analysis and visualization from the trajectories obtained in ReaxFF MD simulations. The interrelationships among the atoms, bonds, fragments, species and reactions are analyzed directly from the three-dimensional (3D) coordinates and bond orders of the atoms in a trajectory, which are accomplished by determination of atomic connectivity for recognizing connected molecular fragments, perception of bond types in the connected fragments for molecules or radicals, indexing of all these molecules or radicals (chemical species) based on their 3D coordinates and recognition of bond breaking or forming in the chemical species for reactions. Consequently, detailed chemical reactions taking place between two sampled frames can be generated automatically. VARxMD is the first tool specialized for reaction analysis and visualization in ReaxFF MD simulations. Applications of VARxMD in ReaxFF MD simulations of coal and HDPE (high-density polyethylene) pyrolysis show that VARxMD provides the capabilities in exploring the reaction mechanism in large systems with complex chemical reactions involved that are difficult to access manually. \u00a9 2014 Elsevier Inc.",

In EBSNs, event recommendation plays a central role in recommending the most relevant events to users who are likely to participate in. Different from traditional recommendation problems, event recommendation encounters three new types of information, i.e., heterogenous online+oflline social relationships, geographical features of events and implicit rating data from users. Yet combining the three types of data for offline event recommendation has not been considered. Therefore, we present a Bayesian latent factor model that can unify these data for event recommendation. Experimental results on real-world data sets show the performance of our method.",

        "abstract": "Email plays a very important role in our daily life. Much work have been put into practice on email network. Those studies mostly require real email network datasets and reliable models to analyze user information and understand the mechanisms of network evolution. However, much research work is constrained by the absence of real large-scale email datasets. Although email communication is ubiquitous, there are very few large-scale available email datasets satisfied different research purposes. Due to privacy policy and restricted permissions, it is arduous to collect a real large-scale email dataset in a short time. Various social network models are usually used to create synthetic email networks. However, these models focus on modeling several structural properties of network without considering user behaviour patterns. They are not appropriate to generate large-scale realistic synthetic email network datasets. Towards this end, we propose a probabilistic model by which we can construct large-scale synthetic email datasets with a small captured email log. What is more important is that the generated synthetic dataset matches real email network properties and individual communication patterns. Moreover, it has linear complexity, and can be paralleled easily. Experimental results on Enron dataset demonstrate the above benefits of our model.",

This paper addresses the stability problem in a dc microgrid with master-slave control structure. Considering the discrete sampling and control algorithm in a digital system, the small-signal models of this dc microgrid have been derived in the z plane. Eigenvalue analysis results show that the system stability and transient response will be affected by the variation of the dc load parameters, the number of slave distributed generations (DGs), and the type of dc load. A centralized oscillation suppression controller, which is composed of a proportional compensator followed by a bandpass filter, is proposed to overcome the unstable oscillations caused by different eigenvalues. The validity of the proposed approach is confirmed by simulations.",

Currently most SWI methods heavily rely on sentiment seed words that have limited sentiment information. Even though there emerge non-seed approaches based on sentiment labels of documents, but in which the context information has not been fully considered. In this paper, based on matrix factorization with co-occurrence neighbor regularization which is derived from context, we propose a novel non-seed model called CONR for SWI. Instead of seed words, CONR exploits two important factors: sentiment matching and sentiment consistency for sentiment word identification. Experimental results on four publicly available datasets show that CONR can outperform the state of-the-art methods.",

        "abstract": "A mature miRNA may be generated from 5p or 3p arm of a hairpin precursor. The selection may be flexible via \"arm switching\". However, accumulating evidences suggest that both arms of many pre-miRNAs can yield mature functional miRNAs. Herein, we attempted to compare the isomiR expression profiles between the two arms through analyzing in-house and published small RNA deep sequencing datasets. Although many miR-#-5p and miR-#-3p have been reported as functional miRNAs, fewer miRNA pairs (11 and 6 pairs are collected in tumor and normal cells, respectively) are simultaneously identified as abundant miRNA species. According to isomiR types and dominant isomiR species, miR-#-5p and miR-#-3p show various isomiR expression profiles as well as diverse enrichment levels. IsomiR profiles of non-dominant arm are not well-conserved in 5' ends as well as isomiR profiles of dominant arm. If both the miR-#-5p and miR-#-3p are abundantly expressed, their isomiR expression profiles are always stable across different samples. Similar to diverse enrichment levels of miR-#-5p and miR-#-3p, the isomiR expression patterns may also be influenced by the phenomenon of \"arm switching\". The diverged isomiR expression profiles further enrich the complexity of multiple isomiRs, and complicate the coding-non-coding RNA regulatory network. \u00a9 2013 Elsevier B.V.",

In order to solve this problem, we study the basic theory of normalized convolution (NC), which include the NC based on polynomial basis function and the least-square solution and propose a novel video sequence super-resolution reconstruction algorithm based on non-local normalized convolution in this chapter. This algorithm can be combined with gray-value information and structural details in the image. The density of sampled data and local structure in edge decide the shape and size of neighborhood in a pixel, so as to design certainty function and structural-adaptive applicability function. Experimental results prove that our proposed algorithm can provide improved denoising effect in the output image and achieve a state-of-art optical resolution in the image edges and detailed features. \u00a9 2014 Springer Science+Business Media New York.",

        "abstract": "Since HTTP is responsible for more than 25% of the total traffic volume in the Internet, we are curious about what happens in the http traffic and what it contains. We collected an anonymized HTTP head only data from a DSL line of a campus's border for continuous 11 days. In this paper, we focus on the user-agent (UA) strings. We first improve a well know open source UASparser, identifying 34.4% (9.8%) more user-agent types (operator system) of overall transactions. In addition, our analysis of user-agent strings shows that Windows XP contributes to more than half of personal computer (PC) HTTP traffic. Mobile devices account for more than 16% of total transactions, and automatic programs share at least 20%. These information leads to following conclusions: PC devices in China are threatened to a huge risk as security support for Windows XP has been stopped recently; mobile devices occupy a big proportion in total transactions of a DSL lines, larger than other researchers [10] noticed 4 or 5 years ago; Android and IOS devices dominate the mobile transactions; automatic programs take up at least one fifth of all HTTP traffic and that means the researcher should no longer ignore the influence of them. \u00a9 Springer International Publishing Switzerland 2014.",

        "abstract": "An integrated humidity sensor capable of passive wireless sensing through inductive coupling is presented. The sensor chip consists of two stacked counter-rotating planar aluminium inductors (0.5 \u03bcm thick, 100 \u03bcm in width, 50 \u03bcm space and 6 mm outer diameter) separated by a maskless polyimide film. The two inductors are inductively and capacitively coupled together to form a resonant tank, whose resonant frequency changes with humidity. This topology eliminates the need of a connection bridge or via as used in the usual inductor- capacitor humidity sensors and offers higher sensitivity due to the inner humidity-sensitive parallel-plate capacitor in contrast with the single-layer self-resonant inductor. Three sensor devices with different inductor turns were fabricated and characterised. Measurements show a sensitivity of 45 kHz/%RH with a centre frequency of 50.5 MHz for sensor A (8 turns), 15.8 kHz/%RH, 22 MHz for sensor B (10 turns) and 65 kHz/%RH, 74 MHz for sensor C (4 turns). \u00a9 The Institution of Engineering and Technology 2014.",

A spline curve smoothing method was applied to restore the 3D morphology of the reference RSA. The proposed protocol was then tested to rebuild the 3D RSA of a shrub (Caragana microphylla) growing in the sandy soils after in situ GPR survey. The accuracy of RSA reconstruction was quantitatively evaluated by a relationship matrix method and qualitatively assessed by direct comparisons between the reconstructed and the actual RSAs after in situ excavation.",

The relevant literature consists only of case reports, and consequently many of its clinical characteristics and optimal treatment strategies remain unknown. Methods: We retrospectively analyzed 23 patients diagnosed with MC of the head and neck between 1991 and 2005. Most patients were treated with surgery and postoperative radiotherapy or adjuvant chemotherapy. The recurrence, survival and local control rates were evaluated. Results: Thirteen (56.5%) patients were male and 10 were female with a median age of 52 years (range: 15-77 years). The parotid was the most frequently involved site (39.1%). Eighteen patients underwent surgery as their initial treatment and nine of these received postoperative radiotherapy. The 3-year and 5-year overall survival rates were 59% and 31.8%, respectively. The local relapse rate was 30.4% (6/23); eight patients had a distal metastasis, and the lung was the most common site. There was no difference in the local control and survival rates between patients who received surgery alone and those with additional postoperative radiotherapy (. p=0.059). Two patients had partial response after chemotherapy with dacarbazine. Conclusions: The detailed clinical data presented here reveal several new characteristics of MC of the head and neck. Postoperative radiotherapy did not improve the prognosis. Chemotherapeutic regimens that include dacarbazine might be useful.",

The problem is defined as, given an activatable set A and a targeted set T, finding the k nodes in A with the maximal influence in T. Different from existing influence maximization work which aims to find a small subset of nodes to maximize the spread of influence over the entire network (i.e., from whole to whole), our problem aims to find a small subset of given activatable nodes which can maximize the influence spread to a targeted subset (i.e., from part to part). Theoretically the new frame includes the common influence maximization as its special case. The solution is critical for personalized services, targeted information dissemination, and local viral marketing on social networks, where fully understanding of constraint influence diffusion is essential. To this end, in this paper we propose a constraint influence maximization frame. Specifically, we point out that it is NP-hard and can be approximated by greedy algorithm with guarantee of 1 - 1/e. We also elaborate two special cases: The local one and the global one. Besides, we present the works that are related and beyond.",

Particularly, by application of coordinate transformation, dimensionality reduction and step fitting of parameters, as well as adoption of reliability test measures of parameters, the mathematical model of data analysis is simplified, the detrimental effects of observation noises and unevenly spatial coverage of sample points are effectively compressed, the stability and precision of parameter solutions are improved, and so the geocentric three-dimensional coordinates of the reference point of this telescope in the precision of millimeters were determined, and the axis-offset was shown not significant on the precision level of 3 mm. The outcome provides important reference to the subsequent activities of antenna maintenance and scientific application, including the establishment of precise antenna orientation model, orientation guidance, fringe searching in data cross-correlation, analysis and application studies of VLBI observations. It is also important archive data for monitoring possible subsidence and lateral displacement of antenna foundation as well as deformation of antenna tracking-rail and structure. \u00a9 2014 Science China Press and Springer-Verlag Berlin Heidelberg.",

        "abstract": "With the motivation of seamlessly extending wireless sensor networks to the external environment, service-oriented architecture comes up as a promising solution. However, as sensor nodes are failure prone, this consequently renders the whole wireless sensor network to seriously faulty. When a particular node is faulty, the service on it should be migrated into those substitute sensor nodes that are in a normal status. Currently, two kinds of approaches exist to identify the substitute sensor nodes: the most common approach is to prepare redundancy nodes, though the involved tasks such as maintaining redundancy nodes, i.e., relocating the new node, lead to an extra burden on the wireless sensor networks. More recently, other approaches without using redundancy nodes are emerging, and they merely select the substitute nodes in a sensor node\u2019s perspective i.e., migrating the service of faulty node to it\u2019s nearest sensor node, though usually neglecting the requirements of the application level. Even a few work consider the need of the application level, they perform at packets granularity and don\u2019t fit well at service granularity. In this paper, we aim to remove these limitations in the wireless sensor network with the service-oriented architecture. Instead of deploying redundancy nodes, the proposed mechanism replaces the faulty sensor node with consideration of the similarity on the application level, as well as on the sensor level. On the application level, we apply the Bloom Filter for its high efficiency and low space costs. While on the sensor level, we design an objective solution via the coefficient of a variation as an evaluation for choosing the substitute on the sensor level.",

While different from existing research on influence maximization area focuses on identifying a seed set to maximize the influence spread over the entire network, this problem focuses on identifying a seed set which can maximize the influence spread to a given target user. For this purpose, we present a solution framework for the proposed target-based influence maximization problem. Specially, we first provide a random function to randomly simulate the objective function of our problem with low variance guarantee.

        "abstract": "The origin and evolution of new microRNAs (miRNAs) is important because they can impact the transcriptome broadly. As miRNAs can potentially emerge constantly and rapidly, their rates of birth and evolution have been extensively debated. However, most new miRNAs identified appear not to be biologically significant. After an extensive search, we identified 12 new miRNAs that emerged de novo in Drosophila melanogaster in the last 4 million years (Myrs) and have been evolving adaptively. Unexpectedly, even though they are adaptively evolving at birth, more than 94% of such new miRNAs disappear over time. They provide selective advantages, but only for a transient evolutionary period. After 30 Myrs, all surviving miRNAs make the transition from the adaptive phase of rapid evolution to the conservative phase of slow evolution, apparently becoming integrated into the transcriptional network. During this transition, the expression shifts from being tissue-specific, predominantly in testes and larval brain/gonads/imaginal discs, to a broader distribution in many other tissues. Interestingly, a measurable fraction (20-30%) of these conservatively evolving miRNAs experience \"evolutionary rejuvenation\" and begin to evolve rapidly again. These rejuvenated miRNAs then start another cycle of adaptive - conservative evolution. In conclusion, the selective advantages driving evolution of miRNAs are themselves evolving, and sometimes changing direction, which highlights the regulatory roles of miRNAs. \u00a9 2014 Lyu et al.",

        "abstract": "DC-bus voltage control is an important task in the operation of a dc or a hybrid ac/dc microgrid system. To improve the dc-bus voltage control dynamics, traditional approaches attempt to measure and feedforward the load or source power in the dc-bus control scheme. However, in a microgrid system with distributed dc sources and loads, the traditional feedforward-based methods need remote measurement with communications. In this paper, a nonlinear disturbance observer (NDO) based dc-bus voltage control is proposed, which does not need the remote measurement and enables the important 'plug-and-play' feature. Based on this observer, a novel dc-bus voltage control scheme is developed to suppress the transient fluctuations of dc-bus voltage and improve the power quality in such a microgrid system. Details on the design of the observer, the dc-bus controller and the pulsewidth-modulation (PWM) dead-time compensation are provided in this paper. The effects of possible dc-bus capacitance variation are also considered. The performance of the proposed control strategy has been successfully verified in a 30 kVA hybrid microgrid including ac/dc buses, battery energy storage system, and photovoltaic (PV) power generation system. \u00a9 2014 IEEE.",

Methods: A retrospective analysis was performed in seven patients with neurobrucellosis in our hospital from January 2002 to May 2013. Results: The proportion of men and women was 6:1, and the average age was 46 years. One case was attacked with the symptoms of cerebrovascular disease, another one with the symptoms of myelitis, and the other five with the symptoms of meningoencephalitis. Six had positive results of serum agglutination test, and the other one had a positive result of blood culture instead. Imaging findings lacked of specificity. There were two patients whose lesions were in the hemisphere cortex, subcortical, basal ganglia and other parts, four patients whose lesions were in the frontal lobe, one in the chest pulp, and one in both sides of cerebellum and pons. After systematical treatment, one case died, the other 6 cases recovered, and no one relapsed or got functional disability during the one-year follow-up. Conclusions: Neurobrucellosis is a rare type of brucellosis, and its clinical manifestations lack of specificity, and imaging and serological detections are important for diagnosis. It is beneficial for patients if diagnosed early and treated systematically, so good understanding of this disease, early diagnosis and treatment are of great value.

        "abstract": "Increasing amounts of evidence indicate that noncoding RNAs (ncRNAs) have important roles in various biological processes. Here, miRNA, lncRNA, and mRNA expression profiles were analyzed in human HepG2 and L02 cells using high-throughput technologies. An integrative method was developed to identify possible functional relationships between different RNA molecules. The dominant deregulated miRNAs were prone to be downregulated in tumor cells, and the most abnormal mRNAs and lncRNAs were always upregulated. However, the genome-wide analysis of differentially expressed RNA species did not show significant bias between up- and downregulated populations. miRNA-mRNA interaction was performed based on their regulatory relationships, and miRNA-lncRNA and mRNA-lncRNA interactions were thoroughly surveyed and identified based on their locational distributions and sequence correlations. Aberrantly expressed miRNAs were further analyzed based on their multiple isomiRs. IsomiR repertoires and expression patterns were varied across miRNA loci. Several specific miRNA loci showed differences between tumor and normal cells, especially with respect to abnormally expressed miRNA species. These findings suggest that isomiR repertoires and expression patterns might contribute to tumorigenesis through different biological roles. Systematic and integrative analysis of different RNA molecules with potential cross-talk may make great contributions to the unveiling of the complex mechanisms underlying tumorigenesis. \u00a9 2014 Li Guo et al.",

The classical multiple string matching algorithms perform poorly on large-scale URLs, due to the heavy consumption of CPU power and memory space. Here we propose a multiple string matching algorithm-SOGOPT for large-scale URL filtering. By exploiting the characteristics of URLs, the proposed algorithm devises two strategies, i. e. the optimal window selection strategy and the pattern set partitioning and reduction strategy, to speed up the classical SOG algorithm. The proposed algorithm improves the searching speed of SOG greatly, especially on large-scale URLs. It is very suitable for large-scale (up to 1 million URLs) and online URL filtering.",

Our method is built on common visual patterns (CVPs), which are the distinctive visual structures between two images and have rich contextual information. With CVPs, two contextual query expansions on visual word-level and image-level are explored, respectively. For visual word-level expansion, we find contextual synonymous visual words (CSVWs) and expand a word in the query image with its CSVWs to boost retrieval accuracy. CSVWs are the words that appear in the same CVPs and have same contextual meaning, i.e. similar spatial layout and geometric transformations. For image-level expansion, the database images that have the same CVPs are organized by linked list and the images that have the same CVPs as the query image, but not included in the results are automatically expanded. The main computation of these two expansions is carried out offline, and they can be integrated into the inverted file and efficiently applied to all images in the dataset. Experiments conducted on three reference datasets and a dataset of one million images demonstrate the effectiveness and efficiency of our method. \u00a9 2014 IEEE.",

        "abstract": "In this paper, we explore a new research problem of predicting an incoming classifier on dynamic data streams, named as forward classification. The state-of-the-art classification models on data streams, such as the incremental and ensemble models, fall into the retrospective classification category where models used for classification are built from past observed stream data and constantly lag behind the incoming unobserved test data. As a result, the classification model and test data are temporally inconsistent, leading to severe performance deterioration when the concept (joint probability distribution) evolves rapidly. To this end, we propose a new forward classification method which aims to build the classification model which fits the current data. Specifically, forward classification first predicts the incoming classifier based on a line of recent classifiers, and then uses the predicted classifier to classify current data chunk. A learning framework which can adaptively switch between forward classification and retrospective classification is also proposed. Empirical studies on both synthetic and real-world data streams demonstrate the utility of the proposed method. \u00a9 2014 Springer International Publishing.",

        "abstract": "Nowadays, the problem of Internet services accessibility has become a hot topic with more and more cyber attacks and censorship. This has prompted the rapid development of jamming-resistance infrastructure consisting of multiple dynamic access points such as proxies, anonymous communication nodes and covert communication nodes. However, the channel between user and access point has become an emerging attacking target for the adversary. Once the channel is detected and identified by the adversary, the channel will be interrupted. Though users can require new access points from the infrastructure and resume the communication to their destination, the service quality will be downgraded dramatically due to the time-consuming bootstrapping process. In this paper, a moving target framework is proposed to improve the network service accessibility, which combines both time-consuming bootstrapping and frequent and low-cost channel refreshing operations. The constant channel refreshing operations is imported to limit the adversary's ability of detecting and blocking communications, thus to make the lifespan of effective communication longer. With theoretical and simulating analysis, the optimized refreshing strategy is proposed, which can help improve service accessibility.",

In the first level, we first train a number of cluster centers, then use the cluster centers to divide the dataset into many clusters and the vectors in each cluster has near uniform distribution. In the second level, we construct LSH tables for each cluster. Given a query, we first determine a few clusters that it belongs to with high probability, and then perform ANN search in the corresponding LSH tables. Experimental results on the reference datasets show that the search speed can be increased by 48 times compared to E2LSH, while keeping high search precision.",

Most work exploits the behavioral analysis to distinguish IWA and non- IWA. These approaches are mainly divided into categories: direct compute method and training learning method. The direct calculation method mainly relies on crawler, and makes multidimensional eigenvector to detect IWA. Nevertheless, it did not consider the behavior rules based on the time sequence, and just determine the user behavior by feather vector, so the results are not very accurate. The recognition rate also needs to be improved. The second method mainly relies on cluster approaches. However, cluster approaches require predetermined the number of clustering, which will directly lead to the model over fitting and owe fitting because of inadequate unit number. In this paper we propose a sequential pattern approach based on DPMM for IWA identification. Firstly, we analyze the user behavior of potential IWA and get a feature vector of user behavior.

        "abstract": "This paper investigates an energy-efficient transmission scheme in cognitive radio networks, where primary users (PUs) may reoccupy the spectrum when secondary users (SUs) is transmitting data. We aim to maximize the energy efficiency by jointly optimizing the transmission power, the fusion rule threshold and the sensing/transmission durations. Firstly, it is derived that for a given fusion rule threshold, the objective function is unimodal while only one optimization parameter varies. Furthermore, we provide the corresponding closed-form expressions of the optimal data transmission duration and transmission power. Finally, the globally unimodal property is proven, and hence, the globally optimal point can be easily found with the proposed algorithm based on the alternating direction method (ADM). Numerical simulation results show that our proposed scheme is much better than the existing ones.",

        "abstract": "Network traffic classification is of great importance for finegrained network management and network security. However, with the rapid development of new network applications in recent years, traffic that cannot be identified by classifiers accounts for an increasing ratio, which brings a great challenge for network operators. Most of the unknown traffic is usually generated by only a few or some certain kinds of applications. We call this kind of traffic as the elephant traffic. It is generally recognized that traffic sharing the same server IP and server port is generated by the same application. In this paper, we say that they are belonging to the same service. Therefore, we propose a novel method, in which service-based statistical features are used for cluster analysis, to classify these elephant traffic. Preliminary results on a real network traffic dataset show that our method is able to automatically identify similar unknown applications. We believe that classifying unknown traffic in service perspective is a promising direction. Copyright is held by the owner/author(s).",

        "abstract": "As a significant milestone in the data dissemination of wireless sensor networks (WSNs), the comb-needle (CN) model was developed to dynamically balance the sensor data pushing and pulling during hybrid data dissemination. Unfortunately, the hybrid push-pull data dissemination strategy may overload some sensor nodes and form the hotspots that consume energy significantly. This usually leads to the collapse of the network at a very early stage. In the past decade, although many energy-aware dynamic data dissemination methods have been proposed to alleviate the hotspots issue, the block characteristic of sensor nodes has been overlooked and how to offload traffic from hot blocks with low energy through long-distance hybrid dissemination remains an open problem. In this paper, we developed a block-aware data dissemination model to balance the inter-block energy and eliminate the spreading of intra-block hotspots. Through the clustering mechanism based on geography and energy, \"similar\" large-scale sensor nodes can be efficiently grouped into specific blocks to form the global block information (GBI). Based on GBI, the long-distance block-cross hybrid algorithms are further developed by effectively aggregating inter-block and intra-block data disseminations. Extensive experimental results demonstrate the capability and the efficiency of the proposed approach. \u00a9 2014 Elsevier Ltd.",

According to the operating characteristics of these distributed generators (DGs), an improved load following (ILF) control strategy is presented to improve the renewable energy penetration and decrease the diesel consumption remarkably, and also to optimize the capacity size and operation conditions of the battery energy storage system (BESS). This ILF strategy uses DE and biomass plant to follow the net load variations at different time scales respectively, and the BESS mainly help to keep the system stabilization. The non-dominated sorting genetic algorithm (NSGA-II) is adopted to solve the multi-objective optimization model considering the net present cost (NPC) and the pollutant emission level in the 20 years full life cycle. The results validate the effectiveness of the proposed method, and show that the proposed solution is reasonable and feasible, meeting diverse demands, as an optimization solution. \u00a9 2014 State Grid Electric Power Research Institute Press.",

        "abstract": "Objective image quality assessment has been widely used in image processing for decades. Many researchers have been studying the objective quality assessment method based on human visual system. Recently, the single-scale feature-similarity index metric has been proposed to provide a good approximation to perceived image quality. However, this metric does not take into account the fact that features in a certain scale cannot reflect various distorted details in the image. To address this issue, this paper proposes a multi-scale structural image quality assessment based on two-stage low-level features, which supplies more flexible than previous single-scale method by incorporating the variations of viewing conditions and resolution. In this multi-scale framework, different weights are assigned to various scales with different levels of importance. Extensive experiments on the five public benchmark databases indicate that the proposed metric is more consistent with the subjective evaluations than all the other competing methods evaluated. \u00a9 2013 Elsevier Ltd.

The present work mainly reviews miRNA/isomiR biogenesis, isomiR expression patterns, and functional and evolutionary implications, especially between isomiRs from homologous and clustered miRNA loci.

        "abstract": "Objective: To investigate the risk factors for pleural lung disease (PLD) in children with juvenile idiopathic arthritis (JIA) and to provide a basis for the early diagnosis and timely treatment of this disease. Methods: A total of 360 children with a confirmed diagnosis of JIA were enrolled, and their clinical data were retrospectively analyzed. All patients underwent a chest X-ray. The patients with PLD were assigned to PLD group, while those without PLD were assigned to non-PLD group. The clinical, imaging, and laboratory results of JIA patients with PLD were analyzed. Results: Among the 360 JIA patients, 43 (11.9%) had PLD, and 9 (21%) of them had respiratory symptoms. Chest X-ray findings mainly included interstitial pneumonitis (53.5%) and pleurisy and/or pleural effusion (38.1%). In the 43 cases of JIA-PLD, 4 (9.3%) had normal chest X-ray findings but abnormal chest CT findings. The incidence of PLD was relatively high in patients aged under 3 years and those aged 12 years or above. Children with systemic JIA had a relatively high incidence of PLD. Compared with the non-PLD group, the PLD group had a significantly higher incidence of anemia, elevated white blood cell (WBC) count and IgG levels in peripheral blood, and positive rheumatoid factors or antinuclear antibodies (P< 0.05). Conclusions: Among children with JIA, PLD is mostly seen in patients with systemic JIA or aged <3 years or \u226512 years, especially those with anemia, elevated WBC count and IgG levels, and positive rheumatoid factors or antinuclear antibodies. For JIA patients with PLD, interstitial pneumonitis is usually seen on chest X-ray or CT, but respiratory symptoms are rarely observed. Routine use of high-resolution chest CT is recommended for early diagnosis and timely treatment of PLD in children with JIA.",

        "abstract": "Background: DNA-binding proteins are vital for the study of cellular processes. In recent genome engineering studies, the identification of proteins with certain functions has become increasingly important and needs to be performed rapidly and efficiently. In previous years, several approaches have been developed to improve the identification of DNA-binding proteins. However, the currently available resources are insufficient to accurately identify these proteins. Because of this, the previous research has been limited by the relatively unbalanced accuracy rate and the low identification success of the current methods.Results: In this paper, we explored the practicality of modelling DNA binding identification and simultaneously employed an ensemble classifier, and a new predictor (nDNA-Prot) was designed. The presented framework is comprised of two stages: a 188-dimension feature extraction method to obtain the protein structure and an ensemble classifier designated as imDC. Experiments using different datasets showed that our method is more successful than the traditional methods in identifying DNA-binding proteins. The identification was conducted using a feature that selected the minimum Redundancy and Maximum Relevance (mRMR). An accuracy rate of 95.80% and an Area Under the Curve (AUC) value of 0.986 were obtained in a cross validation. A test dataset was tested in our method and resulted in an 86% accuracy, versus a 76% using iDNA-Prot and a 68% accuracy using DNA-Prot.Conclusions: Our method can help to accurately identify DNA-binding proteins, and the web server is accessible at http://datamining.xmu.edu.cn/~songli/nDNA. In addition, we also predicted possible DNA-binding protein sequences in all of the sequences from the UniProtKB/Swiss-Prot database.",

        "abstract": "microRNAs (miRNAs) are a class of small non-coding RNAs that deregulate and/or decrease the expression of target messenger RNAs (mRNAs), which specifically contribute to complex diseases. In our study, we reanalyzed an integrated data to promote classification performance by rebuilding miRNA-mRNA modules, in which a group of deregulated miRNAs cooperatively regulated a group of significant mRNAs. In five-fold cross validation, the multiple processes flow considered the biological and statistical significant correlations. First, of statistical significant miRNAs, 6 were identified as core miRNAs. Second, in the 13 significant pathways enriched by gene set enrichment analysis (GSEA), 705 deregulated mRNAs were found. Based on the union of predicted sets and correlation sets, 6 modules were built. Finally, after verified by test sets, three indexes, including area under the ROC curve (AUC), Accuracy and Matthews correlation coefficients (MCCs), indicated only 4 modules (miR-106b- CIT- KPNA2-miR-93, miR-106b- POLQ-miR-93, miR-107- BTRC- UBR3-miR-16 and miR-200c-miR-16- EIF2B5-miR-15b) had discriminated ability and their classification performance were prior to that of the single molecules. By applying this flow to different subtypes, Module 1 was the consistent module across subtypes, but some different modules were still specific to each subtype. Taken together, this method gives new insight to building modules related to complex diseases and simultaneously can give a supplement to explain the mechanism of breast cancer (BC). \u00a9 2014 Elsevier B.V.",

        "abstract": "Regular Expression (RegEx) matching, as a core operation in many network and security applications, is typically performed on Deterministic Finite Automata (DFA) to process packets at wire speed; however, DFA size is often exponential in the number of RegExes. RegEx grouping is the practical way to address DFA state explosion. Prior RegEx grouping algorithms are extremely slow and memory intensive. In this paper, we first propose DFAestimator, an algorithm that can quickly estimate DFA size for a given RegEx set without building the actual DFA. Second, we propose RegexGrouper, a RegEx grouping algorithm based on DFA size estimation. In terms of speed and memory consumption, our work is orders of magnitude more efficient than prior art because DFA size estimation is much faster and memory efficient than DFA construction. In terms of the resulting size sum of DFAs, our work is significantly more effective than prior art because we use a much finer grained quantification of the degree of interaction between two RegExes. For example, to divide the RegEx set of the L7-filter system into 7 groups, prior art uses 279.3 minutes and the resulting 7 DFAs have a total of 29047 states, whereas RegexGrouper uses 3.2 minutes and the resulting 7 DFAs have a total of 15578 states.",

        "abstract": "While mature miRNAs have been widely studied, the terminal loop sequences are rarely examined despite regulating both primary and mature miRNA functions. Herein, we attempted to understand the evolutionary pattern of loop sequences by analyzing loops in the let-7 gene family. Compared to the stable miRNA length distributions seen in most metazoans, higher metazoan species exhibit a longer length distribution. Examination of these loop sequence length distributions, in addition to phylogenetic tree construction, implicated loop sequences as the main evolutionary drivers in miRNA genes. Moreover, loops from relevant clustered miRNA gene families showed varying length distributions and higher levels of nucleotide divergence, even between homologous pre-miRNA loops. Furthermore, we found that specific nucleotides were dominantly distributed in the 59 and 39 terminal loop ends, which may contribute to the relatively precise cleavage that leads to a stable isomiR expression profile. Overall, this study provides further insight into miRNA processing and maturation and further enriches our understanding of miRNA biogenesis. Copyright:",

When undesirable thing such as a rumor or an infection emerges in a social network and part of users have already been infected, our goal is to minimize the size of ultimately infected users by blocking k links. A greedy algorithm with accuracy guarantee and two efficient heuristics for finding approximate solutions to this problem are proposed.

As a popular data model for representing the relations of different data, graph has been widely used in various fields such as analysis of social network, social security, and biological information. Fast and accurate search over the large-scale graph serves as a fundamental problem in graph analysis. In this paper, we survey the up-to-date development in graph pattern matching techniques for graph search from the application perspective. Graph pattern matching techniques are roughly classified into several categories according to the properties of graphs and the requirement of applications. Meanwhile, we focus on introducing and analyzing the exact pattern matching, including non-index matching, index-based matching and their key techniques, representative algorithms, and performance evaluation. We summarize the state-of-the-art applications, challenging issues, and research trends for graph pattern matching.",

        "abstract": "Objective Recent studies suggested a potential of rituximab (RTX) in treating autoimmune thrombocytopenia (AITP) secondary to autoimmune diseases. In this study, we retrospectively evaluated the efficacy and safety of RTX therapy in patients with refractory AITP secondary to systemic lupus erythematosus (SLE) and Sj\u00f6gren syndrome (SS). Methods Twenty-one SLE and/or SS patients with treatment-resistant AITP were treated once or repeatedly with RTX at the Rheumatology Clinic Renji Hospital, during the period March 2012 to June 2014. Clinical and laboratory variables recorded at every follow-up visit were analyzed. Results The median age of all patients was 37.05 \u00b1 3.15 years (range, 13-67 years; 20 female and 1 male). The median AITP duration before RTX treatment was 5.46 years. Previous treatments of 21 patients included immunosuppressive agents such as corticosteroids (n = 19), cyclosporine (n = 9), mycophenolate mofetil (n = 2), methotrexate (n = 3), cyclophosphamide (n = 2), vincristine (n = 3), and hydroxychloroquine (n = 15), and 7 patients received concomitantly intravenous immunoglobulin therapy. Two patients had undergone splenectomy without improvement. Seventeen patients (80.95%) were treated repeatedly with RTX during the follow-up period. The overall response rate to RTX treatment (including complete response, 52.38%; partial response, 28.57%) was 80.95%. A significant increase (P < 0.05) of platelet counts was seen after 1 month (median, 32.24 \u00d7 10<sup>9</sup>/mL vs 66.53 \u00d7 10<sup>9</sup>/mL). Relapses occurred mostly during the first 9 months, and maintaining duration of response was 10.27 months (range, 2-17 months) on average after the first RTX infusion. Antiplatelet antibodies, especially IgG isotype, decreased significantly (P < 0.05) after RTX treatment. No adverse effects were observed among 15 patients (71.4%); however, 2 cases died of severe pneumonia, and another developed lymphoma. Conclusions Rituximab is an additional potent therapeutic treatment option for SLE and SS patients with AITP refractory to conventional immunosuppressive treatments. For most patients, RTX was safe and well tolerated.",

        "abstract": "For text data, feature dimension reduction is a very significant and important work for simplifying document representation and enhancing computation of learning algorithm. There are usually two main dimension reduction strategies, feature extraction and feature selection. Feature extraction is to create new features to represent documents, whereas feature selection will return a subset of words as features. Comparing two strategies, feature extraction has powerful capacity in reducing dimensionality, but it will lost intuitive semantic for documents. Feature selection has perfect interpretability for text contents, and specially is significant for text dimension reduction, but it is still a difficult work to design a suitable measure for feature evaluation. In this paper we present a new feature selection method called class subspace feature selection (CSFS) method. We utilize PCA feature extraction method to capture lower dimensional class subspaces, and then base on the subspaces to choose the most relevant features to the subspaces. The feature words chosen by our method can approximate the class subspace which has lower dimensionality and also owns intuitive semantic understanding for the class. The experimental results on three text data sets show the effectiveness of our proposal feature selection method.",

METHODS: In this prospective case series study, the corneal spherical aberration with 6mm aperture of 73 patients (100 eyes) was measured with KR-1W Visual Function Analyzer 1d before surgery. For the sake of the whole postoperative spherical aberration were close to 0.1\u03bcm, 9 cases (16 eyes) with corneal spherical aberration <0.15\u03bcm were implanted Sofport Advanced Optic IOL, named AO group; 45 cases (57 eyes) with corneal spherical aberration 0.25~0.3\u03bcm were implanted AcrySof IQ IOL, named IQ group; 19 cases (27 eyes) with corneal spherical aberration >0.35\u03bcm were implanted Tecnis ZA9003 IOL, named Tecnis group. Aspherical IOL was implanted after phacoemulsification through a cornea 2.75mm incision without suture. Uncorrected visual acuity, beat corrected visual acuity, spherical aberration of the whole eye and jnternal optics (mainly IOL) at 6mm pupil diameter were examined at 3mo postoperatively. The relevant data were analyzed using t-test and variance analysis. RESULTS: The whole ocular spherical aberration at 6mm pupil diameter in all postoperative were 0.084\u00b10.032\u03bcm; in Tecnis group, the data were 0.091 \u00b1 0.021\u03bcm; in AO group, the data were 0.0814-0.013\u03bcm; IQ group were 0.093\u00b10.042\u03bcm. There was no significantly different between the predicted value and actual value of ocular spherical aberration at 6 mm pupil diameter in all postoperative (t=1.932, P=0.061) and in the three groups. The difference value in the predicted values of the preoperative spherical aberrations of the whole eye and the actual values after surgery was 0.013\u00b10.041\u03bcm; there was no statistically significant difference (F=2.537, P=0.091). Respectively compared the uncorrected visual acuity and besta corrected visual acuity among three groups of postoperative, no significant difference were found (F=0.897, P=0.421; F=1.423, P=0.097). CONCLUSION: Personality selection of aspheric IOL based on preoperative corneal spherical aberration of patients is feasible and produces satisfactory target postoperative total spherical aberration.",

We found that no bias can be detected between the numbers of 5p-miRNA and 3p-miRNA, while miRNAs from miR-#-5p and miR-#-3p show variable nucleotide compositions. IsomiR expression profiles from the two arms are always stable, but isomiR expressions in diseased samples are prone to show larger degree of dispersion. miR-#-5p and miR-#-3p have relative independent evolution/expression patterns and datasets of target mRNAs, which might also contribute to the phenomena of arm selection and/or arm switching. Simultaneously, miRNA/isomiR expression profiles may be regulated via arm selection and/or arm switching, and the dynamic miRNAome and isomiRome will adapt to functional and/or evolutionary pressures. A comprehensive analysis and further experimental study at the miRNA/isomiR levels are quite necessary for miRNA study.",

In particular, a cluster can branch into multiple clusters simultaneously. Intuitively, clusters can evolve as evolutionary trees over time. However, existing models are incapable of recovering the tree-like evolutionary trace in temporal data. To this end, we propose an Evolving Chinese Restaurant Process (ECRP), which is essentially a temporal non-parametric clustering model. ECRP incorporates dynamics of cluster number, parameters and popularity. ECRP allows each cluster to have multiple branches over time. We design an online learning framework based on Gibbs sampling to infer the evolutionary traces of clusters over time. In experiments, we validate that ECRP can capture tree-like evolutionary traces of clusters from real-world data sets and achieve better clustering results than the state-of-the-art methods.",

        "abstract": "Various binary features have been recently proposed in literature, aiming at improving the computational efficiency and storage efficiency of image retrieval applications. However, the most common way of using binary features is voting strategy based on brute-force matching, since binary features are discrete data points distributed in Hamming space, so that models based on clustering such as BoW are unsuitable for them. Although indexing mechanism substantially decreases the time cost, the brute-force matching strategy becomes a bottleneck that restricts the performance of binary features. To address this issue, we propose a simple but effective method, namely COIP (Coding by Order-independent Projection), which projects binary features into a binary code of limited bits. As a result, each image is represented by one single binary code that can be indexed for computational and storage efficiency. We prove that the similarity between the COIP codes of two images with probability proportional to the ratio of their matched features. A comprehensive evaluation with several state-of-the-art binary features is performed on benchmark dataset. Experimental results reveal that for binary feature based image retrieval, our approach improves the storage/time efficiency by one/two orders of magnitude, while the retrieval performance remains almost unchanged.",

        "abstract": "Currently, a growing number of attack sources of distributed denial of service (DDoS) are migrating to cloud computing and bringing a greater security challenge to the whole cyberspace. However, the research on effectively suppressing these attack sources is still deficient. So, this paper proposes a method pTrace to defeat the DDoS attack sources in cloud, which comprising the packet filter module inFilter and the malicious process retroactive module mpTrace. inFilter mainly filters packets with forged source address. And, mpTrace firstly identifies attack streams and their corresponding source addresses, then trace malicious processes based on the obtained source addresses. We have implemented a prototype system under Openstack and Xen environment. Experimental results and analysis show that inFilter can prevent large-scale DDoS attack frombeing launched in cloud center with lower time consumption, and mpTrace can identify a attack flow correctly when its flow rate is about 2.5 times the normal traffic, tracing malicious processes in ms time level. At last, this method reduces the impact both on puppet cloud tenant and the victim outside cloud.",

Traditional techniques become unqualified because they need seed sentiment words which may lead to low robustness. This paper presents an optimization-based framework by incorporating sentiment contextual information instead of seed words. Specifically, we exploit two sentiment phenomena: (1) sentiment matching: polarities of the document and its most component sentiment words are the same, and (2) sentiment consistency: polarities of two frequently co-occurring words are the same. Empirical results demonstrate that our models significantly outperform the existing approaches.",

Most existing researches do not make a distinction between sentiment classification and topical text classification. Actually, the former commonly depends more on features conveying sentiments while the latter depends on features with strong class distinguish-ability. Therefore, traditional topical feature selection approaches might not be applicable to SFS. In this paper, we propose a novel matrix factorization model for SFS. Our model exploits the sentiment labels of documents to predict words' sentiment distinguish-ability. Our experiments show that the extracted features are highly accurate and significantly improve the performance in sentiment classification.",

        "abstract": "Text corpus and link network are interrelated data in social networks. Discovering the inner relationship between these two kinds of data can help better understand the evolution mechanism underneath social networks. Moreover, social networks exhibit unique characteristics such as sparse and noisy in both text and link data. Thus, it is imperative to combine both text and link data to complement and correct mining results. However, previous work did not explore a uniform generative model that can unveil their inner relationship probably because of the difficulty to harness the heterogenous data in social networks. To address this issue, in this paper we present a generative model Topic Block that clearly pinpoints the latent concept underlying the text corpus and link network, i.e., User inner interests. In our generative model, user inner interests guide the generation of the topic and community distributions underlying the text corpus and link data. We can infer the topic and community distributions based on the user inner interests through both content and topology information. Compared to existing popular models, our method experimentally outperforms on three real world social network data sets.",

In this paper, we propose a new cognitive scheme which has two cognitive sub-networks sharing the same relay station, considering the interference to the primary user. We study the Weighted Rate Balance problem with the constraint of the transmit power of the cognitive network. Joint beamforming at the cognitive base station and the relay station is used to maximize the Weighted Rate Balance of SUs. To solve the non-convex problem, we adopt the classic altering optimization method, namely the Blahut-Arimoto algorithm. We show that we only need to solve several semidefinite programming(SDP) sub-problems, which have linear matrix inequalities(LMIs), in each iterative step. Simulation results show that, compared with the widely studied diagonally structured beamforming design, the proposed approach performs better.",

Chloride diffusion processes in concrete nanochannels are simulated with the molecular dynamics method. Correspondingly, microscopic mechanism of effects of constrictivity and tortuosity is obtained. Fick's law is adopted to analyze the simulated results, which clarifies the effect degrees of constrictivity and tortuosity on chloride diffusivity. The results show that ions distribution in pore fluid is affected by bound chlorides in nanochannel walls, leading to formation of positron layers which adsorb free chlorides and reduce their diffusion rate. The larger the bound chloride concentration, the smaller the chloride diffusivity. Atomic potentials of nanochannel walls also affect ions distribution. As nanochannel width increases, chloride diffusivity is larger. In tortuous nanochannel, the transport direction of chlorides can be changed, which reduces their diffusion rate.",

Compared with the predicted value of yield strength by thermal mismatch model and Orowan model, the experiment value indicates that the mechanism of CNTs/Al5083 accords with Orowan mechanism.",

        "abstract": "To investigate rock fragmentation process under disc cutter and how cutter-ring structure affects cutter-rock interaction, a 3D cutter-rock interaction model based on discrete element method was build. Contact force, micro crack development and crack balls during cutting process were studied. Furthermore effect of cutter edge width and angle on rock fragmentation was analyzed, and the mapping relationship between ring structure and cutting efficiency was established. Results show that the micro failure of rock is mainly due to tensile crack, and fragmentation is an acceleration process. Cutter edge width affects cutter-rock interaction more than cutter edge angle, with cutter force and crack rock volume increase obviously when cutter edge width increases. Based on the mapping relationship, the ring structure for 17\u2033 disc cutter was designed, and the optimized edge width and angle were obtained.",

Most of the existing methods perform this task based solely on observed facts. The only requirement is that the learned embeddings should be compatible within each individual fact. In this paper, aiming at further discovering the intrinsic geometric structure of the embedding space, we propose Semantically Smooth Embedding (SSE). The key idea of SSE is to take full advantage of additional semantic information and enforce the embedding space to be semantically smooth, i.e., entities belonging to the same semantic category will lie close to each other in the embedding space. Two manifold learning algorithms Laplacian Eigenmaps and Locally Linear Embedding are used to model the smoothness assumption. Both are formulated as geometrically based regularization terms to constrain the embedding task. We empirically evaluate SSE in two benchmark tasks of link prediction and triple classification, and achieve significant and consistent improvements over state-of-The-Art methods. Furthermore, SSE is a general framework. The smoothness assumption can be imposed to a wide variety of embedding models, and it can also be constructed using other information besides entities' semantic categories.",

For power limitation above set point in high wind speed, the pitch control will be effective in controlling the output power and the rotor speed. However, this method does not make the best use of the turbines aerodynamic characteristics to optimize the operation conditions in middle and low wind speed. Based on analysis of the full-range WPCC operational characteristics, a novel WPCC (N-WPCC) strategy had been proposed through the combination of active turbine speed control and pitch regulation. Theoretical analysis and simulation results show that, through giving priority to the torque control than the pitch regulation compared with the traditional WPCC, N-WPCC can effectively decrease the frequency and amplitude of the pitch actor, thus to extend its operating life, and can also improve the power generation to some extent because of taking the full advantage of the turbines vast rotational inertia. In addition, the control input data of the proposed method are related with the output power and rotor speed rather than the wind speed.",

        "abstract": "Ensemble learning is a common tool for data stream classification, mainly because of its inherent advantages of handling large volumes of stream data and concept drifting. Previous studies, to date, have been primarily focused on building accurate ensemble models from stream data. However, a linear scan of a large number of base classifiers in the ensemble during prediction incurs significant costs in response time, preventing ensemble learning from being practical for many real-world time-critical data stream applications, such as Web traffic stream monitoring, spam detection, and intrusion detection. In these applications, data streams usually arrive at a speed of GB/second, and it is necessary to classify each stream record in a timely manner. To address this problem, we propose a novel Ensemble-tree (E-tree for short) indexing structure to organize all base classifiers in an ensemble for fast prediction. On one hand, E-trees treat ensembles as spatial databases and employ an R-tree like height-balanced structure to reduce the expected prediction time from linear to sub-linear complexity. On the other hand, E-trees can be automatically updated by continuously integrating new classifiers and discarding outdated ones, well adapting to new trends and patterns underneath data streams. Theoretical analysis and empirical studies on both synthetic and real-world data streams demonstrate the performance of our approach.",

CO<inf>2</inf> could be chemically activated through an organic base dissociated from the parent catalyst during the reaction, while niobate anions played a crucial role in immobilizing catalytically active organic cations and thus improving the recyclability of the catalyst. The structural characterization of the catalysts indicated that peroxoniobate anions had undergone structural changes and were transformed into more stable niobate anions in the consecutive recycles. It was shown that the catalyst could be reused with high conversion and selectivity by a really straightforward process. Furthermore, this protocol was found to be applicable to a variety of epoxides producing the corresponding cyclic carbonates in high conversion and selectivity.

Here, we applied a comparative proteomic strategy, based on 2D and MALDI-TOF/MS platforms, to examine the differential expression of proteins in MDBK cells that were treated and not treated with virulent IBRV LN01/08 and attenuated IBRV LNM strains. A total of eight differential proteins, including pyruvate kinase, heat shock protein (HSP) 90 (HSP90AA1 and HSP90AB1), annexin A, albumin (ALB), scinderin (SCIN), tubulin (alpha 1a) and vimentin (VIM), were identified. Among these proteins, pyruvate kinase, and HSP90 (HSP90AB1), tubulin and vimentin were identified in the virulent IBRV LN01/08 strain group, but were not identified in the attenuated IBRV LNM group. These results play an important role in tumor formation and development, cell migration, tumor cell line apoptosis, cell invasion and viral infection. The HSP90 (HSP90AA1) protein was identified in the control group and the attenuated IBRV LNM-infected group. Most studies have shown that HSP90 proteins were more of a cancer gene target, and inhibiting its function would result to oncogene degradation during cancer treatment. On the other hand, ALB is associated to cell differentiation, apoptosis, necrosis, cell death, viral infection, autophagy, interstitial tissue inflammation, and cell survival. These results provide a theoretical basis for the systematic understanding of BHV-1-infection mechanisms and BHV-1-induced immune responses.",

However, our understanding of the role of ApoE in Wilson's disease is limited. High copper concentration in Wilson's disease induces excessive generation of free oxygen radicals. Meanwhile, ApoE proteins possess antioxidant effects. We therefore determined whether copper-induced oxidative damage differ in the liver of wild-type and ApoE knockout (ApoE<sup>-/-</sup>) mice. Both wild-type and ApoE<sup>-/-</sup> mice were intragastrically administered with 0.2 mL of copper sulfate pentahydrate (200 mg/kg; a total dose of 4 mg/d) or the same volume of saline daily for 12 weeks, respectively. Copper and oxidative stress markers in the liver tissue and in the serum were assessed. Our results showed that, compared with the wild-type mice administered with copper, TBARS as a marker of lipid peroxidation, the expression of oxygenase-1 (HO-1), NAD(P)H dehydrogenase, and quinone 1 (NQO1) significantly increased in the ApoE<sup>-/-</sup> mice administered with copper, meanwhile superoxide dismutase (SOD) activity significantly decreased. Thus, it is concluded that ApoE may protect the liver from copper-induced oxidative damage in Wilson's disease.",

        "abstract": "AgBr nanoparticles loaded BiPO<inf>4</inf> microrods have been successfully synthesized via a facile deposition-precipitation method. XRD, FE-SEM, TEM, EIS, UV-Vis-DRS techniques were employed to characterize the phase composition, morphology and light absorption properties of the as-synthesized samples. Methylene blue (MB) and phenol (Ph) were selected as model pollutant to investigate the photocatalytic activity of the as-synthesized samples under visible-light irradiation. The experimental results show that different amount of AgBr on BiPO<inf>4</inf> exhibit an obvious effect on the degradation of MB and the optimum molar ratio of AgBr and BiPO<inf>4</inf> is 1 : 10. In particular, the photocatalytic activity of AgBr/BiPO<inf>4</inf> is superior to the activities of two individual photocatalyst, indicating the presence of a synergic effect between two component in AgBr/BiPO<inf>4</inf>. On the basis of photocatalytic results and energy band diagram, the activity enhancement mechanism of AgBr/BiPO<inf>4</inf> composite has also been investigated. The p-type semiconductor AgBr and n-type semiconductor BiPO<inf>4</inf> can match each other and form a novel p-n heterojunction, thus increasing the photogenerated electron-hole pair separation efficiency. Therefore, this work provides some help for the design of novel and efficient BiPO<inf>4</inf>-based photocatalyst with multi-components for enhancing visible-light-driven photocatalytic activity.",

The secondary network is a distributed wireless self-organization network transmitting messages with collaborative beamforming. A multi-antenna target unknown eavesdropper (TUE), whose wiretap target is not assumed, appears in the CRN. A specific application of spectrum leasing is designed to ensure the secrecy performance of the whole network, in which the SUs access the spectrum in reward of helping improve the secrecy performance of the entire CRN. The transmit signals of the secondary network are designed to ensure the secrecy rate performance of both the primary and the secondary networks. To make it solvable with a method based on parameterizing the power gain region, the secrecy rate balancing problem is relaxed. The relaxation is further proved to be tight and the relaxed problem is equivalent to the original problem. Finally, we use a two-dimensional search to achieve the optimal transmit beamformer. According to the simulation, the proposed beamforming strategy enjoys an obvious performance gain comparing to the traditional zero-forcing beamforming.",

        "abstract": "Influence maximization, defined as finding a small subset of nodes that maximizes spread of influence in social networks, is NP-hard under both Independent Cascade (IC) and Linear Threshold (LT) models, where many greedy-based algorithms have been proposed with the best approximation guarantee. However, existing greedy-based algorithms are inefficient on large networks, as it demands heavy Monte-Carlo simulations of the spread functions for each node at the initial step [7]. In this paper, we establish new upper bounds to significantly reduce the number of Monte-Carlo simulations in greedy-based algorithms, especially at the initial step. We theoretically prove that the bound is tight and convergent when the summation of weights towards (or from) each node is less than 1. Based on the bound, we propose a new Upper Bound based Lazy Forward algorithm ( UBLF in short) for discovering the top-k influential nodes in social networks. We test and compare UBLF with prior greedy algorithms, especially CELF [30]. Experimental results show that UBLF reduces more than 95 percent Monte-Carlo simulations of CELF and achieves about $2\\hbox{-}10$ times speedup when the seed set is small.",

        "abstract": "The Ziyuan-3 (ZY-3) satellite was designed to satisfy 1:50000 scale mapping requirements. This study uses 556 images obtained by ZY-3, from June 1 to October 31, 2013, covering an area of 3 500 000 km <sup>2</sup> in midwestern China. A total of 900 check points measured by a global positioning system were also used to conduct the planar accuracy verification. The experimental results show that the ZY-3 nadir sensor calibration images achieved a planar root mean square error (RMSE) of 10.8 m without the use of ground control points (GCPs). In addition, the verification of vertical accuracy employed 12 ZY-3 stereo image pairs distributed over an area of 14 000 km <sup>2</sup> around Taiyuan in the Shanxi Province of China, and a Digital Elevation Model with 0.5-m vertical accuracy was used for reference and validation. The vertical accuracy of forward interaction and stereo-extracted Digital Surface Model (DSM) from the stereo images were both validated without GCPs. The experimental results demonstrate that the overall vertical RMSE of the forward intersection was 6.58 m; it was 5.21 and 7.07 m for flat and mountainous terrain, respectively. Moreover, the overall vertical RMSE of DSM was 5.56 m; it was 4.37 and 5.69 m for flat and mountainous terrain, respectively. It can be seen from the experimental results of planar and vertical accuracy verification that ZY-3 imagery is able to satisfy the requirements of 1:50000 topographic mapping in China without using GCPs.",

        "abstract": "The cutterhead endures strong, multi-point distributed impact loads when the full face rock tunnel boring machine (TBM) tunnels, which leads to intense vibration and fatigue fracture. Accordingly the structure should meet the requirement of service life considering the fracture failure at weak locations. Hence, cutterhead damage mechanism is crucial to predict and analyze residual life of a operational cutterhead under impact loads. This paper combines with the characteristics of cutterhead life, Paris model and damage cumulative theory, proposes a new failure criterion for the long thick plate in complex stress states, and establishes a segmented crack propagation life prediction model, based on the existing multi-degree-of-freedom coupling dynamic TBM cutterhead model and fatigue crack propagation prediction method for large and complex structures. Meanwhile, a physical fatigue damage test of cutterhead specimens is carried out to validate the theoretical model. Then a TBM cutterhead in a water tunnel project is taken as an example, to calculate the fatigue crack propagation and analyze how different parameters affect fatigue life. The results of the analyses reveal that with fatigue crack propagation, life of actual cutterhead is 36.5. km, which gives a meaningful reference for cutterhead design. In addition, the cutterhead life decreases nearly 45.2% with the initial crack depth increasing from 0.5. mm to 2. mm, and it is inferred that the value of initial crack depth should be controlled below 1.6. mm, to ensure the service life. On the other side, the larger the crack shape ratio (a/c), the longer the fatigue life, and the cutterhead life with a round crack (a/c= 1) is about 3 times with a narrow crack (a/c= 0.1). Furthermore, the crack growth rate parameter m has greater influence on cutterhead life than parameter C, with C increasing 10%, the life decreases about 9%; however, the life decreases nearly 13% when m increases 1%. Then, the critical threshold values of cutterhead material parameters to meet life requirement are obtained. From the results of fatigue damage test, it can be showed that the specimens fracture quickly when the crack depth exceeds 50% of the panel thickness, and the crack shape ratio gradually increases with the loading cycles, which is consistent with the theoretical assumption, as well as the influence rules of parameters.",

Methods: We treated a series of 18 patients (34 eyes) with genetic ectopia lentis whose visual acuity did not improve with optical phakic or aphakic correction, or with modern microsurgery and automated suction- cutting devices. Laser interferometry and electroretinogram (ERG) were used for the examination of retinal function before surgery. Results: There was not significant difference between the interferometric acuity before operation and the corrected visual acuity after operation (p>0.05), and the coincidence rate between them was 80% (27 eyes). ERG examination showed normal function in most of the patients. Conclusions: The results showed that the laser interferometric acuity is a valuable method in evaluation of postoperative visual acuity in patients with ectopia lentis. In six eyes, the LIVA was lower than the initial corrected vision postoperatively, but ERG examination showed that the retinal function was normal in these patients. Therefore, in patients with genetic ectopia lentis, LIVA combined with ERG predicts visual acuity more accurately.",

        "abstract": "Objective To determine the sensitivity and specificity of using a computer-photoscreener and non-cycloplegic retinoscopy in the detection of amblyopiogenic factors in nine to fifty months old infants and children. Methods Three hundred children, nine to fifty months old, were screened with the computer-photoscreener and non-cycloplegic retinoscopy. With a blinded standardized clinical assessment as the standard, an overall comparison of the sensitivity of and specificity results obtained with the two techniques was made. Photoscreen images on the computer monitor screen were reviewed and analyzed immediately by two independent observers for indicators of amblyopiogenic risk factors. Simultaneously, the results were compared to the findings of a full ophthalmologic examination. Results The computer-photoscreener revealed a sensitivity of 94.6% and specificity of 90.1%, and the non-cycloplegic retinocopy revealed a sensitivity of 85.7% and specificity of 81.0% for the detection of amblyopiogenic risk factors, including hyperopia ( +2.75 D or more), myopia ( - 1.50 D or more), astigmatism (1.75 D or more), anisometropia (2.00 D or more), ocular misalignment (5 degrees or more), and media opacity (1.5 mm or more). Conclusions The computer-photoscreener offers an opportunity to identify problems that limit vision, and could provide a feasible and sufficiently reliable screening technique in infants and preschool children to be screened successfully for amblyopiogenic risk factors.",

Methods: After de-capsulated, rat or bovine lenses were homogenized and centrifuged individually to get water soluble protein. Bovine \u03b3-crystallins were separated through a column of Sephadex G-200 superfine. \u03b3-crystallin was acetylaled by reaction with N-acetylimidazole in vitro. 2DE and MALDI-TOF-MS were performed to separate and identify lens protein. Results: 2DE pattern of rat water-soluble lens proteins showed more than 20 spots with molecular weight of 18 \u223c 30 kDa. Of the identified protein spots, \u03b1-crystallin comprised approximately 19% of the soluble protein of rat lens, \u03b2-crystallin 43% and \u03b3-crystallin 36%. Bovine \u03b3-crystallins, separated by gel filtration, mainly consisted of five spots on 2DE gel. The major 3 intensive spots (\u03b3B, \u03b3D, \u03b3s) accounted for 90% of \u03b3-crystallin on 2DE gel. After acetylation of \u03b3-crystallin with N-acetylimidazole, 2DE gel patterns showed an increase numbers of spots with acidic shift. Conclusion: Two-dimensional gel electrophoresis integrated with mass spectrometry is a rapid and highly sensitive technique to the analysis of lens protein and its modification.",

Methods: Genomic DNA was collected from 204 probands with high myopia and 112 unrelated persons without high myopia. The coding sequences of TGIF gene in 316 subjects were analyzed by using exon-by-exon PCR-heteroduplex-SSCP analysis and sequencing. Results: There were 3 types of SNP and one single nucleotide mutation in the coding sequence of TGIF gene: IVS-2 nt350 G \u2192 T (36/204), codon140 CCA \u2192 CCG; Pro140Pro, codon163 CCG \u2192 CTG; Pro163Leu and codon126 GTG\u2192GCG; Val126Ala(1/204). The SNPs of codon140 CCA\u2192CCG and codon163 CCG\u2192CTG were composed of 3 alleles and 5 genotypes in Chinese population which abide by Hardy-Weinberg law. Conclusion: There was no evidence to prove that mutations in the TGIF gene are responsible for the high myopia in Chinese. Three SNPs of coding sequence TGIF gene in Chinese population abide by Hardy-Weinberg law.",

Methods: The primary mtDNA mutations (3460A, 11778A and 14484C) of 156 patients (110 probands and 46 maternal relatives with LHON) were detected by mutation-specific priming polymerase chain reaction, heteroduplex-single strand conformation polymorphism polymerase chain reaction, restriction fragment length polymorphisms and measurement of DNA sequence. The clinical features were analyzed by retrospective study. Results: The 11778A mutation was found in 100 probands (90.9%), the 3460A mutation was found in 2 (1.8%), and the 14484C was found in 8(7.3%) of the 110 probands.

The atmospheric model for correction of tropospheric radio refraction and its parameters have been given in charts and tables. The parameters include the refractivity at sea level, on the ground, above 1km and elevation of 9km and other altitude. It also includes the horizontal and vertical gradient of the refractivity and vapor density. The statistical results provide the basic environmental data for the correction and prediction of the refractive effect of radio wave system and of communication system signal loss.",

By considering power utilization, uniformity and the effect on resolution, it was found that binary grating illumination is an effective approach.

        "abstract": "The overall goal of this article is to address the shortcomings of the current literature by providing a systematic estimate of the volume of labour flow, describing the composition of the labour force and analysing the determinants of labour flow. Having a better picture of China's labour movements may help leaders to understand how many people participate in China's trans-regional labour market, who benefits, and which factors encourage some to enter and prevent others from leaving home. This information should facilitate better policy-making. The article uses a theoretical framework to analyse the determinants of migration systematically, to formulate predictions of which factors affect labour movement and to test competing hypotheses raised in the literature. In this article we seek to answer several questions about the contribution of four factors to migration: the income level of those who choose to migrate, chain migration, rural institutions and human capital. First, are the poor and those without local wage-earning opportunities more likely to migrate, or the rich and those with skills valuable in the city? Secondly, is chain migration important? If so, what are the key elements that make it important? Do information and the social network that conveys that information matter most, or are transportation costs and proximity to urban regions vital? Thirdly, do rural institutions prevent people from leaving the village, push people off the farm, or are they neutral, perhaps weakened by the rise of markets? Finally, does human capital, in particular education, facilitate entrance into the migrant labour force? Or is education inconsequential? Drawing on our own extensive survey of 200 villages, we estimate that 154 million people from rural areas of China worked off-farm in 1995, including 54 million long-term migrants and over 15 million self-employed who have left their villages. Some of our major findings are that rural migration has created one of the main opportunities for women to enter the off-farm labour force and that rural migrants are moving progressively further away from home. Our analysis also demonstrates that being part of a network of labourers (or being involved in chain migration) is key to facilitating labour movement out of a village. Transportation and rural institutional barriers are not formidable obstacles to migration. The following section introduces our data. The next three sections offer descriptive evidence of labour movements in China's rural villages and present an analytical framework for explaining migration. The sixth section raises a number of hypotheses suggested by the descriptive data and previous studies, and the final sections present our results and offer conclusions.",

Respondents were asked to provide information about a number of areas, including their training and counseling activities and their perceptions of several areas related to the development of counseling in China. The results suggested that most counselors had received little formal training in counseling, and counseling was often done in the context of political and thought education. Respondents perceived themselves as needing more training in practical counseling skills than in Western counseling theories. They perceived limited resources and a lack of professionally trained counselors as major barriers. The results are discussed in relation to the future development of counseling at universities in China.",

        "abstract": "A carbonate crust, with a principally digitate structure, caps latest Permian reef complexes in east Sichuan, China. The crust contains the conodont Hinedodus parvus, confirming its age as earliest Triassic; it therefore closely postdates the end-Permian mass extinction, and is related to associated palaeoenvironmental change. Although its branches have lobate margins, and internal structures of radial fabrics and lobate fabrics in different specimens, an organic origin cannot be confirmed, because crust fabric is largely recrystallised. Therefore we apply the term ?microbialite to reflect uncertainty of its nature. The crust is co-eval (within the parvus Zone) with confirmed microbial biostromes and mounds in Guizhou Province, south of Sichuan. The sum of evidence, assembled by workers in several sites worldwide, indicates a sea-level rise occurred in the boundary interval, and this is corroborated by facies of the Sichuan crust. Abrupt appearance and disappearance of the crust, formed by precipitated carbonates, in east Sichuan, represents short-lived unusual post-extinction marine conditions which were switched abruptly on, then off. Microbial deposits overlying the P/T boundary in other locations in the Tethys Ocean (Iran and Japan) support the view that the unusual oceanic conditions had at least a regional distribution. Because the crust abruptly terminates, and is not succeeded by fossil-rich deposits, application of the disaster biota concept is inappropriate; an environmentally-driven control on carbonate precipitation is better supported by the evidence, whether or not it was biotically-mediated.",

        "abstract": "Silurian reefs are well known to comprise frame-building corals, stromatoporoids and algae, but also a range of calcimicrobial components and micritic sediments of possible microbial origin. The margins of Wenlock patch reefs tend to have diffuse edges that grade into the surrounding bedded facies because of talus shed from the reefs. However, portions of patch reefs show sharp-bounded reef margins, with bedded limestones terminating abruptly against the reef edge, Examples of sharp boundaries where the reef comprises only carbonate mudstone-wackestone with poorly-defined gross fabric, and containing no metazoan framework, have been found in Wenlock patch reefs the UK and Gotland. Although in some cases the micrite may demonstrate a peloidal structure, in others there is no clear structure, broadly fitting the aphanitic (structureless) type of fabric found in leiolites (suspected microbial facies that show no structure). The fabrics are interpreted to have been formed by microbial mediation of micrite precipitation as part of reef construction, and are therefore automicrites. In all cases the sharp reef edges indicate coherence of the micritic fabric, interpreted as a lithified wall against which bedded limestones were deposited. This arrangement supports published interpretations of pronounced topography of Wenlock patch reefs, and shows the presence of steep, vertical and, possibly, overhanging reef margins, formed prior to bedded sediment accumulation. Thus, there is likely to have been a time interval between reef formation and deposition of bedded sediments, possibly caused by reef upward growth in transgressive settings, followed by catch-up of bedded limestone deposition. \u00a9 The Geological Society of London.",

        "abstract": "Earliest Triassic microbialites (ETMs) and inorganic carbonate crystal fans formed after the end-Permian mass extinction (ca. 251.4 Ma) within the basal Triassic Hindeodus parvus conodont zone. ETMs are distinguished from rarer, and more regional, subsequent Triassic microbialites. Large differences in ETMs between northern and southern areas of the South China block suggest geographic provinces, and ETMs are most abundant throughout the equatorial Tethys Ocean with further geographic variation. ETMs occur in shallow-marine shelves in a superanoxic stratified ocean and form the only widespread Phanerozoic microbialites with structures similar to those of the Cambro-Ordovician, and briefly after the latest Ordovician, Late Silurian and Late Devonian extinctions. ETMs disappeared long before the mid-Triassic biotic recovery, but it is not clear why, if they are interpreted as disaster taxa. In general, ETM occurrence suggests that microbially mediated calcification occurred where upwelled carbonate-rich anoxic waters mixed with warm aerated surface waters, forming regional dysoxia, so that extreme carbonate supersaturation and dysoxic conditions were both required for their growth. Long-term oceanic and atmospheric changes may have contributed to a trigger for ETM formation. In equatorial western Pangea, the earliest microbialites are late Early Triassic, but it is possible that ETMs could exist in western Pangea, if well-preserved earliest Triassic facies are discovered in future work. \u00a9 Springer-Verlag 2007.",

Wistar rates were subjected to establish the animal models of SCII. Hemodynamic changes of the lumbar spinal cord were measured through laser Doppler flowmetry. Morphologic changes were examined by microscopy and fluorescence microscope. The expression of IEGs was detected through immunohistochemistry method. Results. After 30min of ischemia, the spinal cord blood flow (SCBF) reduced rapidly by 85.3%. The SCBF increased immediately at the moment of reperfusion onset and reached the peak value after 10 min of reperfusion. The SCBF approximately recovered the baseline level after 30min of reperfusion and the decreased gradually. Some rats appeared the symptom of secondary paralysis after ischemical reperfusion. Under the fluorescence microscope, the morphological changes of apoptosis appeared in spinal cord nerve cells after ischemia and reperfusion, including nucleus pyknosis, aggregate at the edge of nucleus karyotheca and so on. Fos and Jun positive immunoreactive neurons were detected in the experimental groups after 30min of reperfusion, but rarely detected in the control group. Conclusion. The reperfusion injury occurs after spinal cord ischemical reperfusion. The overexpressions of c-fos and c-jun take part in the apoptosis of spinal cord nerve cells.",

Objective: To investigate the ability of MSCs to differentiate into neuron in vitro in rat. Design: A randomly blank-control study. Setting, Materials and Interventions: Research was completed at Toxicology Department of Public Health School of Jilin University. Six-week old Wistar rats of either gender obtained from experimental animal center of Jilin University were employed. The 2nd to 4th generation of rMSCs were inoculated on 24-well plates covered by microscopic coverglass. There were 3 experiment groups and one control group. Isobutylmethylxanthine (IBMX) with a concentration of 0.25, 0.50 and 1.00 mmol/L was added respectively into 3 experiment group to induce rMSCs generation. Morphologic observation was operated after cellular differentiation. There was no inductive agent added into control group. Cellular identification was operated by immunocytochemistry. Main Outcome Measures: The growth of cultured MSCs; cellular morphologic changes after induction; the immunocytochemical assay of nestin (mouse antirat, monoclone), neuron-specific enolase(NSE) antibody(rabbit anti mouse, mutil-antibodies), and microtubule-associated protein-2a, b (MAP-2a, b). Results: After being added with IBMX, there was little neuron-like cells differentiation in 0.25 mmol/L group; cells in 0.1 mmol/L group gradually died since the 2nd day; neuron-like cells could be seen on the 2nd day in 0.5 mmol/L group with typical morphological characteristics. 0.5 mmol/L IBMX had a best inductive effectiveness. Neuron-like cells could be seen on the 2nd day and on the 6th day, neuron-like cells were with (23.2 \u00b1 2.3) % of the total cells, NSE dye reaction was positive. Non-differentiating cellular expression was nestin. With 3-day induction, positive cells increased, and decreased on the 6th day. Conclusion: rMSC can be amplified, generated in vitro and to be induced into early phase neuron-like cells.",

        "abstract": "Objective: To explore the way to induce mesenchymal stem cells (MSCs) to differentiate into dopaminergic neurons in vitro. Methods: MSCs were obtained from rat bone marrow, cultured and passaged. MSCs used in this experiment had multipotency, which was indirectly proved by being induced to differentiate into chondrocytes and adipocytes. MSCs were cultured in medium containing 0.5 mmol/L IBMX for 2 days. Then the medium was replaced with induction medium, which contained GDNF, IL-1\u03b2, mesencephalic glial-cell-conditioned medium and flash-frozen mesencephalic membrane fragments. The surface markers of the differentiated neurons, such as NSE, nestin, MAP-2a, b and TH were detected by immunocytochemistry and Western blot after MSCs were cultured in induction medium for 7 days and 15 days. Results: MSCs differentiated into neural progenitors and expressed nestin after MSCs were incubated with medium containing IBMX for 2 d. After the medium was replaced with induction medium containing many inducing agents, MSCs differentiated into neuron-like cells and dopaminergic neuron-like cells and expressed NSE, MAP-2a, b and TH. The percentage of NSE-positive cells, MAP-2a, b-positive cells and TH-positive cells was 30.032\u00b12.489%, 41.580\u00b15.101% and 34.958\u00b15.534%, respectively after MSCs were induced in medium containing GDNF, IL-1\u03b2, mesencephalic glial-cell-conditioned medium and flash-frozen mesencephalic membrane fragments for 15 days. Conclusion: MSCs can differentiate into dopaminergic neuron-like cells and are a new cell source for the treatment of neurodegeneration diseases and have a great potential for wide application.

The tibial angle was measured after X-ray check. T test was used for data analyzing. HE stain, toluidine blue Dyeing and immunohistochemistry test were performed to observe the histomorphology. Results: The tibial angle of lower extremity was (38.80 \u00b1 13.50)\u00b0 in control group, (9.01 \u00b1 4.2)\u00b0 in artificial epiphyseal plate group 8 weeks after transplantation; (54.25 \u00b1 18.33)\u00b0 in control group, (11.27 \u00b1 5.1)\u00b0 in artificial epiphyseal plate group 24 weeks after transplantation. There was significantly difference between control group and artificial epiphyseal plate group (P< 0.01 ). There was bony bridge formation in control group. 2 weeks after planting, the epiphyseal plate impairment region was filled with cartilage tissue, but the chondrocytes in the transplanted epiphyseal plate were changed into irregular arrangement, and demarcation was distinct with normal epiphyseal plate cartilage. After planting for 4 weeks, cartilage layers were noted in the treatment groups and the cutting edges disappeared. There were collagen- II -positive cells in transplanted epiphyseal plate cartilage. Conclusion: The artificial epiphyseal plate can repair the epiphyseal plate injury, and the effect is satisfied.",

        "abstract": "Objective: To observe the expressions of glial cell line derived neurotrophic factor (GDNF) and it's receptor after transplanting mesenchymal stem cells (MSCs) to rats with middle cerebral artery occlusion (MCAO). Methods: Adult Wistar rats were randomly divided into MSCs transplantation group (transplantation group), equivalence saline injection group (saline group) and sham-operation group. At the 1st, 3rd, 5th, 7th day after transplantation, the expressions of GDNF protein, GFR\u03b11 and c-Ret mRNA were detected by using immunohistochemical and in situ hybridization. Results: The GDNF positive cells at the periphery were more than those in ischemic center, and at the 7th day after transplantation of MSCs, the expression of GDNF was higher than those in sham-operation and saline groups (P<0.05). The GFR\u03b11 and c-Ret mRNA can be detected in the integrated neurons. At the 7th day, the expressions of GFR\u03b11 and c-Ret mRNA in transplantation group were higher than those in sham-operation and saline groups (P<0.05). Conclusion: MSCs can secrete and/or promote the nerve cells secrete GDNF, and increase the expression of GDNF receptors in neuron. MSCs may play a great role in the treatment of the central nerve system diseases.",

Results of structural characterization indicate that all of the as-prepared samples have sin-gle wurtzite ZnO structure. The images of scanning electron microscopy and transmission electron microscope show that the regular dubble-prismlike ZnO microcrystals were obtained under the condition of adding CTAB and SDS at the same time. UV-Vis absorption spectra demonstrate that the dubble-prismlike ZnO microcrystals have strong absorption band between 200-420 nm and exhibit high photocatalytic activity in the degradation of the wastewater of cigarette factory, COD removal ratio of wastewater is 84.7%. Furthermore, the growth mechanism of dubble-prismlike ZnO microcrystals was also discussed.",

        "abstract": "Objective: To study the capability of bone marrow mesenchymal stem cells (BMSCs) in promoting the recovery of renal ischemia-reperfusion injury and provide a new method for the treatment of renal diseases. Methods: BMSCs were cultivated and amplified in vitro from bone marrow cell suspension of healthy 3-week-old C57BL/6J mice. 8-week-old C57BL/6J mice were randomly divided into sham operation group (n = 16), parallel control group (n = 16) and cell transplantation group (n = 16). The renal ischemia-reperfusion injury model was established. BMSCs were transplanted into the mice in cell transplantation group via the tail vein and saline was injected into the mice in parallel control group. Renal function, such as the level of serum urea nitrogen (BUN) and creatinine (Cr), the indexes of renal oxidative stress, such as the levels of hydroxyl radical and superoxide anion, morphologic changes and renal pathological changes were detected. Results: Circled digit one BMSCs not only had a high purification, homogeneity and stability, but also had unlimited proliferation. Circle digit two The mice in parallel control group appeared the poor state. The indexes of renal function and oxidative stress were obviously increased. And there were collapse of renal glomerulus, disappearance of renal tubule and infiltration of inflammatory cells in renal tissue. Transplanted mice appeared the good state. The indexes of renal function and indexes of oxidative stress had been significantly improved (P<0.05). The renal pathological changes were not obvious. Conclusion: BMSCs are easily isolated and cultivated in vitro.

The optical focusing property was tested using a simple experimental setup. Moreover, the lens imaging functions 'JLU' and '' (English and Chinese abbreviations for Jilin University) were also demonstrated. In order to further enhance the diffraction efficiency, four-level and eight-level FZPs were designed using theoretical calculation and rapidly realized by point-to-point femtosecond laser scanning. In this way, the diffractive efficiency was enhanced from 35.8% for the two-level phase lens to 67% for the four-level phase lens and 73.9% for the eight-level phase lens, which are the largest values reported so far. \u00a9 2010 IOP Publishing Ltd.",

Atomic force microscopy (AFM) characterization shows that surface height of the micropatterns was lower than the rest of the film due to the loss of oxygen confirmed by XPS and XRD techniques. The electric resistivity and conductivity of as-reduced graphene have strong dependences on output power of femtosecond laser. Moreover, current-voltage curves of graphene microcircuits show typical linear relationship, indicating the stable conductivities. The micro-nanoprocessing of graphene through femtosecond laser technologies might open the door for applications of graphene-based materials in electronic microdevices. \u00a9 2010 Elsevier Ltd.

The study indicates that at pH 4.0 Fe(III) is reduced to Fe(II) by methimazole and in situ formed Fe(II) reacts with potassium ferricyanide to give soluble Prussian Blue which is characterized by means of XRD analysis. The absorbance of Prussian Blue is measured at the absorption maximum of 735 nm, and the amount of methimazole can be determined based on this absorbance. Beer's law is obeyed in the range of methimazole concentrations of 0.02-6.00 \u03bcg/mL. The equation of the linear regression is A = -0.0058 + 0.49988c (\u03bcg/mL), with a correlation coefficient of 0.9998 and RSD of 0.80%.

        "abstract": "The pig is the non-primate species that is immunologically closest to humans, and has been considered as an alternative source to human allografts for transplantation. In fact, there has been recent interest in identifying and culturing porcine neural progenitor cells (PNPCs) in vitro, but the long-term culturing has not yet been characterized. Here, we reported the spontaneous differentiation of PNPCs into neuronal and glial cells. For in vitro cultures, the primary cells of the subventricular zone of the forebrain striatum were cultured in the presence of epidermal growth factor and basic fibroblast growth factor to allow the growth of spherical masses that exhibit sustained growth and self-renewal capacity. After growth factor removal, the neurospheres with 10 and 130 days of culture spontaneously differentiated into Tuj1-positive neurons and GFAP-positive astrocytes as seen by double immunocytofluorescence. Molecular characterization using reverse transcription-polymerase chain reaction showed that neurospheres expressed nestin, neuron-specific enolase, and glial fibrillary acidic protein (GFAP). In addition, after cultured in the differentiation medium for 3 months, the growth of neurosphere became slow and displayed cystic structures with the same morphology as that of embryonic bodies derived from embryonic stem cells. It is concluded that PNPCs have the ability to provide an expandable source of neural cells that can develop into neuronal and glial subtypes. \u00a9 2011 Springer Science+Business Media B.V.",

        "abstract": "Reported here is femtosecond laser mediated bandgap tailoring of graphene oxides (GOs) for direct fabrication of graphene-based microdevices. When femtosecond laser pulses were used to reduce and pattern GO, oxygen contents in the reduced region could be modulated by varying the laser power. In this way, the bandgap of reduced GO was precisely modulated from 2.4 to 0.9 eV by tuning the femtosecond laser power from 0 to 23 mW. Through the first-principle study, the essence of GO bandgap tailoring is proved to be femtosecond laser reduction induced oxygen-content modulation. As representative illustrations, bottom-gate graphene FETs were fabricated in situ by using femtosecond laser reduced GO as the channel material, and an optimized room temperature on-off ratio of 56 is obtained. The controlled reduction of GO by femtosecond laser contributes great potential for bandgap tailoring and microdevices patterning of graphene toward future electronics. \u00a9 2012 American Chemical Society.",

Hierarchical graphene nanostructures were formed after laser interference treatment of graphene oxide, which holds great promise for gaseous molecular adsorption, and thereby significantly increases their sensing performance. By tuning the laser power, the content of oxygen functional groups, could be changed within a certain range, which contributes not only controllable conductivity but also tunable response/recovery time of the humidity sensor due to the interaction between water molecules and oxygen functional groups on the graphene oxide sheets. The laser interference processing of graphene oxide films is a mask-free, surfactant-free and large-area approach to the production of hierarchical graphene micro-nanostructures, and thus shows great potential for fabrication of future graphene-based microdevices. \u00a9 2011 Elsevier Ltd.

        "abstract": "Cold stress is generally considered to suppress the immune system and may lead to an increase in the occurrence of disease in the presence of a pathogen. The immune system is ordinarily brought back to a baseline response level after immune challenge through homeostatic processes in part regulated by the cytokines. Often, findings reported from various studies investigating the effects of stress on the cytokines are conflicting. This is due to some conditions has limited the accumulation of information on effects of cold stress on cytokine profile. The present study investigated the effects of multiple cytokines in response to a given stressor to understand the role of cytokines in the immunological responses to different duration of cold stress exposure in rats. Thus, researchers simulated animals' hypothermia life environment, using Luminex xMAP and evaluated the effect of cold stress for pro-inflammatory cytokines (IL-1 [3,IL-6 and TNF-a), chemokine interferon-y-inducible protein-10 (IP-10), Thl (IL-2 and IFJST-y) and Th2 (IL-4 and IL-10) type of cytokine in serum of SPF Wistar rats. Irrespective of the duration, cold stress enhanced levels of proinflammatory cytokine IL-6. Acute cold stress up-regulated TNT-a, IP-10, IL-2 and IL-4 levels. TNF-a, IL-2 and IL-4 levels showed down-regulate trends compared with the acute cold stress treatment groups in the duration of chronic cold stress. BothlFN-y and IP-10 levels increased significantly in cold stress 9 and 12 days. These data demonstrate that cold stress enhances pro-inflammatory cytokines profile and alterations of Thl and Th2 type cytokines secretion in serum of rats. With the extension of the cold stress time, the cellular adaptive immune response and to some extent, the nonspecific humoral immune response was also affected. \u00a9 2012 Medwell Journals.",

        "abstract": "Zi geese (Anser anser domestica) belong to the white geese and are excellent layers with a superior feed-to-egg conversion ratio. Quantitative gene expression analysis, such as Real-time qRT-PCR, will provide a good understanding of ovarian function during egg-laying and consequently improve egg production. However, we still don't know what reference genes in geese, which show stable expression, should be used for such quantitative analysis. In order to reveal such reference genes, the stability of seven genes were tested in five tissues of Zi geese. Methodology/Principal Findings: The relative transcription levels of genes encoding hypoxanthine guanine phosphoribosyl transferase 1 (HPRT1), \u03b2-actin (ACTB), \u03b2-tubulin (TUB), glyceraldehyde-3-phosphate- dehydrogenase (GADPH), succinate dehydrogenase flavoprotein (SDH), 28S rRNA (28S) and 18S rRNA (18S) have been quantified in heart, liver, kidney, muscle and ovary in Zi geese respectively at different developmental stages (1 d, 2, 4, 6 and 8 months). The expression stability of these genes was analyzed using geNorm, NormFinder and BestKeeper software. Conclusions: The expression of 28S in heart, GAPDH in liver and ovary, ACTB in kidney and HPRT1 in muscle are the most stable genes as identified by the three different analysis methods. Thus, these genes are recommended for use as candidate reference genes to compare mRNA transcription in various developmental stages of geese.

        "abstract": "In view of mass-production and solution-processing capabilities, graphene oxides (GOs), generally prepared by chemical oxidation of graphite and subsequent exfoliation in aqueous solution, are widely used as an effective route to graphene-like materials. However, the oxygen-containing groups (OCGs) on the graphene sheets make GO insulating, which significantly restricts its applications, especially for electronics. Therefore, reduction methods that are used to remove OCGs become critical. In recent years, in addition to thermal and chemical reduction, photoreduction has emerged as an appealing alternative because photoreduction does not rely on either high temperature or toxic chemicals. In this progress report, the recent development of the photoreduction of GOs and their unique properties are highlighted, as well as their related applications. Photoreduction strategies including photothermal reduction, catalytic/catalyst-free photochemical reduction, and solid state/in-solution laser reduction are summarized. Moreover, photoreduction of GO permits exquisite control over film conductivities, residual oxygen contents, porosity, and surface wettability, which lead to various functionalities towards a wide range of applications, such as field-effect-transistors (FETs), flexible electrodes, sensors, supercapacitors, Li-ion batteries, photovoltaic devices, and photocatalysis. It is anticipated that, with the rapid progress of photoreduction methodology, GOs would be more competitive in the graphene-oriented applications. \u00a9 2013 WILEY-VCH Verlag GmbH & Co.

The effects of pine needle fiber content on the tribological properties of the friction composites were tested using a friction material tester at constant speed. Experimental results showed that the friction coefficient of the pine needle fiber reinforced friction composites was very stable and markedly fade was not obvious compared with specimen FC0 (containing 0 wt% pine needle fibers); the wear rates of the friction composites generally increased with the increase of temperature and were significantly influenced by the test temperature. The wear rate of specimen FC7 (containing 7 wt% of pine needle fibres) was the lowest compared with that of other specimens at each temperature, except for that when the temperatures were about 200 \u00b0C. Morphologies of wear surfaces of pine needle fiber reinforced friction composites were observed using scanning electron microscopy (SEM) and the friction characteristics were analyzed. The results showed that the worn surface of specimen FC7 was smoother compared with that of specimen FC0. \u00a9 the Partner Organisations 2014.",

        "abstract": "Friction material is essential for automotive braking system. Based on previous study of existing friction material problems, hybrid biological fiber-reinforced resin-based friction materials (HBRMs, from the reinforced fiber component of resin-based friction materials) were explored in this study. Bamboo fiber, jute fiber and wool fiber (all have length of 3-5 mm) were processed to make three types of HBRMs and considered as three factors of biological reinforced fiber in test using orthogonal experimental design. Each factor had three levels of 1%, 2% and 3% fiber mass fraction while the ratio of other raw materials remains unchanged. According to the orthogonal experimental design table, nine formulations (denoted as M1-M9) were determined to test the HBRMs. For comparison, non-bio-fiber reinforced friction material (NBM) was added in the test. The properties of the HBRMs tested included Rockwell hardness, impact strength and density. The friction and wear performance of the braking materials was examined by a speed friction tester. The results show that the friction coefficient of the HBRMs was slightly higher than that of the NBM, indicating biological fibers affected the friction coefficient. The friction coefficient of the HBRMs decreased firstly with the increase of temperature and had the lowest value when the temperature reached 300\u00b0C, and it increased then as temperature increased. During recovery process, the friction coefficient of the HBRMs firstly increased with the decrease of temperature and then decreased greatly when the temperature dropped to 100\u00b0C. The wear rates of the HBRMs increased with the increase of temperature and reached maximum value when temperature reached 200\u00b0C, then it decreased with the increase of temperature. The results of fuzzy comprehensive evaluation analysis on the friction coefficient and wear rate show that the best comprehensive properties were presented when the mass fraction of bamboo, jute and wool fiber were 3%, 3% and 1%, respectively. \u00a9 (2014) Trans Tech Publications, Switzerland.",

In order to evaluate the effect of ENO1 on follicle-stimulating hormone receptor (FSHR) mRNA and luteinizing hormone receptor (LHR) mRNA of primary granular cell from goose F1 follicles, the recombinant plasmid adenovirus carrying ENO1 were constructed and infected the primary culture granular cells. The granular cells were randomly divided into three groups: recombinant adenovirus infected (pAd-CMV-ENO1), empty vector infected (pAd-CMV-Null) and no virus (mock control). The expression levels of FSHR mRNA and LHR mRNA of granular cells were examined by qRT-PCR. The results showed the group pAd-CMV-ENO1 had significantly higher FSHR mRNA expression levels than the other two groups (P < 0.05), but had significantly lower LHR mRNA expression levels than the other two groups (P < 0.05). The results suggested that ENO1 could improve the combination rate between FSH and FSHR to accelerate the proliferation and differentiation and steroidogenesis in poultry gonadal tissues. \u00a9 2014.",

        "abstract": "Bone marrow mesenchymal stem cells can differentiate into neurons and astrocytes after transplantation in the spinal cord of rats with ischemia/reperfusion injury. Although bone marrow mesenchymal stem cells are known to protect against spinal cord ischemia/reperfusion injury through anti-apoptotic effects, the precise mechanisms remain unclear. In the present study, bone marrow mesenchymal stem cells were cultured and proliferated, then transplanted into rats with ischemia/reperfusion injury via retro-orbital injection. Immunohistochemistry and immunofuorescence with subsequent quantifcation revealed that the expression of the axonal regeneration marker, growth associated protein-43, and the neuronal marker, microtubule-as-sociated protein 2, significantly increased in rats with bone marrow mesenchymal stem cell transplantation compared with those in rats with spinal cord ischemia/reperfusion injury. Furthermore, the expression of the autophagy marker, microtubule-associated protein light chain 3B, and Beclin 1, was significantly reduced in rats with the bone marrow mesenchymal stem cell transplantation compared with those in rats with spinal cord ischemia/reperfusion injury. Western blot analysis showed that the expression of growth associated protein-43 and neuro-flament-H increased but light chain 3B and Beclin 1 decreased in rats with the bone marrow mesenchymal stem cell transplantation. Our results therefore suggest that bone marrow mesenchymal stem cell transplantation promotes neurite growth and regeneration and prevents autophagy. These responses may likely be mechanisms underlying the protective effect of bone marrow mesenchymal stem cells against spinal cord ischemia/reperfusion injury.",

        "abstract": "The paper discussed the protective effect of zinc pretreatment on renal ischemia-reperfusion injury (RIRI) and its mechanism. 50 male ICR mice were randomly divided into five groups: sham-operated group, model group, high-dose group with zinc sulfate pretreatment (60mg/kg body weight), medium-dose group with zinc sulfate pretreatment (30mg/kg body weight) and low-dose group with zinc sulfate pretreatment (15mg/kg body weight). The mice were administrated with zinc sulfate once a day for two weeks, subsequently the RIRI animal models were prepared by ligation of the left renal pedicle 30 minutes. 24h after reperfusion, the kidney tissue was removed and pathological results by HE staining showed that in the model group, kidney surface covered with a large number of red exudates, renal tubular dilatated, disorganized, renal tubular epithelial cell vacuolar degenerated, nuclear pyknosis and necrosis appeared; congestive and necrosis were visible in medullary junction. The pathological changes of renal ischemia- reperfusion were obviously relieved in the animals with medium and low-dose zinc pretreatment. The superoxide dismutase (SOD) activity in the lowdose zinc sulfate pretreatment group was significantly higher than that in the model and high-dose groups (P <0.05). The malondialdehyde (MDA) content of renal tissue, the apoptotic cells percentage in the medium and low dose groups were significantly lower than those in the model group (P <0.05), and MDA content in the low-dose group was significantly lower than that in the medium dose group (P <0.05). The ratio of BCL-2/BAX protein expression in the medium and low dose groups was significantly higher than that in the model group (P<0.05), the ratio in the low groups was significantly higher than that in the medium dose and high dose group by double immunofluorescence staining (P <0.05). In conclusion, zinc has a protective effect on the renal ischemia-reperfusion injury by antioxidant capacity and inhibition of apoptosis in the kidney.",

        "abstract": "Objective: To investigate the repair effect of transplantation of bone marrow mesenchymal stem cells (BMSCs) on liver injury in severe burned rats, and to clarify its mechanism. Methods: The BMSCs of rats were isolated, cultured, amplified, identified, and labeled in vitro. 30 Wistar rats were randomly divided into normal control group(n = 10), model group(n = 10) and cell therapy group(n = 10). The burned rat model was established. The BMSCs labeled by chlormethyl-benzamidodialkylcarbocyanine(CM-Dil) were transplanted into the rats in cell therapy group by retro-orbital intravenous injection and the saline was injected into the rats in model group. The general status of all rats were observed. The liver tissues of rats were obtained 2 weeks after transplantation, and the pathohistological changes were observed and the pathohistological scores were detected; the apoptotic rate of liver cells was detected by TUNEL method; the engraftment of BMSCs in liver tissues of the rats was observed under laser scanning confocal microscope. Results: 2 weeks after transplantation, the rats in model group were obviously malaise dispirited and the rats in cell therapy group showed obviously better, and the body weight of the rats in cell therapy group was higher than that in model group(P<0.05). The pathohistological results showed the normal liver lobules of the rats in model group disappeared, and the liver cords disordered, and some liver sinusoids dilated and congested, lymphocytes infiltrated with occasional focal aggregating, and cell edema was found, cytoplasm loose and steatosis were seen in liver tissue. However, the pathohistological changes of liver tissue of the rats in cell therapy group were significantly better than those in model group. The pathohistological score of the rats in cell therapy group was significantly lower than that in model group(P<0.05). The TUNEL staining results showed that there were lots of apoptotic liver cells in liver tissue of the rats in model group, and the apoptotic rate of liver cells in cell therapy group was significantly lower than that in model group(P<0.05). CM-Dil labeled BMSCs were found in liver tissue of the rats in cell therapy group under confocal microscope. Conclusion: BMSCs can implant into the damaged liver tissue after transplantation, and BMSCs have an obvious repair effect on liver injury caused by burning, and the possible mechanism may be associated with the inhibiting of apoptosis.",

        "abstract": "It is unknown whether transplantation of bone marrow mesenchymal stem cells (BM-MSCs) can repair spinal cord ischemia-reperfusion injury (SCII) in a rat model through an anti-apoptotic effect. Adult rats were divided into untreated or sham-operated controls, untreated models of SCII (uSCII) and BM-MSC-transplanted models of SCII (tSCII; labeled with CM-Dill transplanted at 1 h and 24 h after reperfusion). According to evaluation of hind-limb motor function, the motor functions of tSCII rats were significantly better than those of uSCII rats by the seventh day. H&E and TUNEL staining showed that the spinal cords of uSCII rats contained damaged neural cells with nuclear pyknosis and congestion of blood vessels, with a high percentage of apoptotic neural cells, while the spinal cords of tSCII rats were nearly normal with significantly fewer apoptotic neural cells. Immunohistochemistry and double immunofluorescence staining revealed that in tSCII rats CASP3 and neurofilament-H (NF-H) levels were 14.57% and 174% those of uSCII rats, respectively, and in tSCII rats the ratio of BAX to BCL2 was reduced by nearly 50%. The differentiation of transplanted CM-Dil-labeled BM-MSCs into neurons and astrocytes was observed in the spinal cords of the tSCII rats under laser scanning confocal microscopy. These results showed that transplantation of BM-MSCs improved functional recovery after SCII via anti-apoptosis. \u00a9 2014 Elsevier B.V. All rights reserved.",

        "abstract": "The surfaces of jute fibers (Corchorus capsularis L.) were processed to have different dumbbell-shaped spacing (5 mm, 10 mm, 15 mm, and 20 mm), and the physical properties of the modified surfaces of the jute fibers were evaluated in this study. The dumbbell-shaped jute fiber (DJF)-reinforced friction materials were prepared through compression mold. The friction and wear performance of the DJF were tested using a friction material tester at constant speed. The results showed that the dumbbell-shaped spacing has less influence on the friction coefficients of friction materials. The friction coefficients of DJF have bigger fluctuation compared with that of straight fiber during the temperature-increasing procedure. The wear rate of DJF with dumbbell-shaped spacing of 15 mm was the lowest, except for that when the temperatures were about 200-250\u00b0C. Morphologies of wear surfaces of DJF were observed using scanning electron microscopy and the friction characteristics were analyzed. The results showed that reinforced with DJFs in the friction materials can reduce the specific wear rate and the variation in friction coefficient compared with that of straight jute fibers. \u00a9 2014 Wiley Periodicals, Inc.

        "abstract": "In a previous study, we found that the global genome organizer Special AT-rich binding protein 1 (SATB1) is highly expressed in mesenchymal-derived human osteosarcoma U2OS cells and that the knock-down of SATB1 results in the inhibition of cell proliferation. The present study was aimed at investigating the effect of silencing SATB1 on cell migration, invasion, apoptosis and resistance to the chemotherapeutic drug arsenic trioxide. Cell migration and invasion were detected by wound-healing assays and trans-well invasion assays, respectively. Cell apoptosis was analyzed by an in situ Cell Death Detection POD Kit, based on terminal deoxynucleotydyl transferase mediated dUTP nick-end labeling (TUNEL) staining and mRNAs were analyzed by real time qRT-PCR. We found that cell migration and invasion were inhibited and that the proportion of apoptotic cells and sensitivities to the chemotherapeutic drug arsenic trioxide were enhanced by knockdown of SATB1 in U2OS cells. Furthermore, mRNA of ABCC1 and ABCG2 were decreased strikingly after SATB1 silencing. It was concluded that the elevated expression of SATB1 in U2OS cells contributes to maintenance of the malignant phenotype and resistance to chemotherapeutic drugs ATO, suggesting that silencing SATB1 in the cells might improve the effects of arsenic trioxides in the treatment of osteosarcoma in which SATB1 is over-expressed and that ABCC1 and ABCG2 were involved in SATB1 mediated resistance of U2OS cells to ATO.",

Methods: 40 Wistar rats were randomly divided into blank control group, low dose group (0.2 mg \u2022 kg<sup>-1</sup> CdCl<inf>2</inf>), middle dose group (0.4 mg \u2022 kg<sup>-1</sup> CdCl<inf>2</inf>) and high dose group (0.8 mg \u2022 kg<sup>-1</sup> CdCl<inf>2</inf>), and there were 10 rats in each group. The cadmium chloride solution was administrated by intraperitoneal injection to prepare the rat models of kidney damage. The same volume of normal saline was injected into the rats in blank control goup. The general status and body weights of all rats were observed. The kidney tissue and blood of the rats were obtained 5 weeks later. The renal function indexes including creatinine, blood urea nitrogen, and \u03b22-microglobulin were detected; the levels of cadmium in the kidney tissue of the rats in various groups were detected by atomic absorption spectrometry; the relative expression level of LC3B and expression level of Beclinl protein were detected by Western blotting and immunohistochemical methods, respectively. Results: Obvious depression was seen in the rats in CdCl<inf>2</inf> groups, and the body weights of the rats in high dose group were significantly lower than those in blank control group from 3 weeks after exposure to cadmium (P<0.05); the body weights of the rats in middle dose group and high dose group were significantly lower than those in blank control group at the end of this experiment (P<0.05). The results of blood biochemical detection showed that the levels of creatinine, blood urea nitrogen, and \u03b22-microglobulin of the rats in middle dose group and high dose group were significantly higher than those in blank control group (P<0.05), and the levels of creatinine of the rats in high dose group were significantly higher than those in low dose group (P<0.05); the levels of blood urea nitrogen of the rats in middle dose group and high dose group were significantly higher than those in low dose group (P<0.05). The results of atomic absorption spectrometry showed that there were a small amount of cadmium accumulation of the rats in blank control group, but a large amount of metal cadmium accumulated in the kidney tissue were seen in low, middle and high dose groups and the levels of cadmium were increased with the increasing of the exposure dose; the levels of cadmium of the rats in middle dose group and high dose group were significantly higher than those in low dose group (P< 0.05); the levels of cadmium of the rats in high dose group were significantly higher than those in middle dose group (P<0.05). The immunohistochemistry results showed that the expression levels of Beclinl protein in the kidney tissue of the rats in CdCl<inf>2</inf> groups were significantly higher than those in blank control group (P<0.05), and the expression levels of Beclinl protein of the rats in middle dose group and high dose group were significantly higher than those in low dose group (P<0.05); the expression levels of Beclinl protein of the rats in high dose group were significantly higher than those in middle dose group (P<0.05). The Western blotting results showed that the relative expression levels of LC3B protein in the kidney tissue of the rats in CdCl<inf>2</inf> groups were significantly higher than those in blank control group (P<0.5), and the relative expression levels of LC3B protein in the kidney tissue of the rats in middle dose group and high dose group were significantly higher than those in low dose group (P<0.05). Conclusion: At the range from 0.2 to 0.8 mg \u2022 kg<sup>-1</sup>, the kidney damage gets more and more serous with the increasing of the exposure dose of CdCl<inf>2</inf>, and autophagy may be one of the mechanisms.",

To better understand the degree of pollution caused by those PMs, it is necessary to conduct real-time measurement, such as particle sizes and concentrations and so on. The main aim of this study is to evaluate the possibility and effectiveness of the aerodynamic particle sizer (APS) on measuring PM emitted from AFOs. An APS was firstly employed to measure the size distribution of the glass sphere powder and vegetable oil with different attributes in the laboratory. The measurement results were compared with those simultaneously measured by micro-orifice uniform deposit impactor (MOUDI). Then particulate matter emitted from a cattle feedlot was measured by APS at real-time. The result showed that APS performed well when using it to measure two types of glass sphere powder and vegetable oil in the laboratory. According to linear regression analysis, there was correlation between the cumulative mass concentrations of glass sphere powder obtained by APS and MOUDI, as well as the vegetable oil. Both of the values of determination coefficient R<sup>2</sup> were greater than 0.9. APS also performed well when using it to measure the particulate emitted from the cattle feedlot since it well recorded the pollution scenarios and reflected the variation of the air pollutant. APS provided values of geometric mean diameter, number concentration and mass concentration, which can be used to evaluate pollution level of particulates emitted from animal feeding operation from different aspects.",

The determination whether the spot signal is performing well or not is easily to make by inspecting the typical parameters of these signals and comparing the results with the normal values. Thus in an automatic fault diagnose system, to recognize signal waveform automatically is the most important process in troubleshooting. This paper primarily introduced a method of waveform recognition based on computer correlate examination.",

        "abstract": "When the survey data sampled by multiple sensors are adopted to estimate the parameter under the interference of measurement noise, the multisensor data fusion demands timeliness and spatiality. In order to improve the measurement precision, based on the parameter estimation theory, a spatial-temporal estimation algorithm for multi-sensor data fusion is presented. The process of this algorithm can be divided into recursive fusion estimation based on time and adaptive weighted fusion algorithm based on space. The algorithm needs no prior probability distributing knowledge of measurement data, and is easy to realize with simple programming and calculation. The simulation results show that this algorithm is better than those separately based on time or space in reducing measuring error.",

The effluent concentration of COD can meet the second order of Comprehensive Sewage Discharge Standard (GB8978-1996) and was close to the first order. The second chamber and the third chamber of ABR had a crucial role for treating domestic sewage, except the first one. The removal efficiencies were satisfactory when a hydraulic retention time (HRT) was 6-10 h at about 18\u00b0C, which were better than those of UASB reactor. It represented the advantages of the tertiary anaerobic reactor, and showed enormous potential and wide foreground for treating organic contamination by ABR reactor. The effluence from ABR should be post-treated by an aerobic biofilter. All of the indexes can meet the first order of discharge standard except phosphate and total organic phosphor (TP).

        "abstract": "Chinese herbal medicines possess the therapeutic potential for mood disorders. This double-blind, randomized, placebo-controlled study was designed to evaluate the efficacy and side effects of the herbal medicine called Free and Easy Wanderer Plus (FEWP) as an adjunct to carbamazepine (CBZ) in patients with bipolar disorders. One hundred and twenty-four bipolar depressed and 111 manic patients were randomized to treatment with CBZ alone, CBZ plus FEWP, or equivalent placebo for 12 weeks. CBZ was initiated at 300 mg/day and FEWP was given at a fixed dose of 36 g/day. Efficacy measures included the Hamilton Rating Scale for Depression, Montgomery-Asberg Depression Rating Scale, Young Mania Rating Scale, Bech-Rafaelsen Mania Scale, and Clinical Global Impression-Severity (CGI-S). CBZ monotherapy produced significantly greater improvement on manic measures at week 2 through endpoint and CGI-S of depression at endpoint compared to placebo. CBZ monotherapy also yielded significantly higher clinical response rates than placebo on bipolar depression (63.8% vs. 34.8%, p = 0.044) and mania (87.8% vs. 57.1%, p = 0.012). Compared to CBZ monotherapy, adjunctive FEWP with CBZ resulted in significantly better outcomes on the three measures of depression at week 4 and week 8 and significantly greater clinical response rate in depressed subjects (84.8% vs. 63.8%, p = 0.032), but failed to produce significantly greater improvement on manic measures and the response rate in manic subjects. There was a lesser incidence of dizziness and fatigue in the combination therapy compared to CBZ monotherapy. These results suggest that adjunctive FEWP has additive beneficial effects in bipolar patients, particularly for those in depressive phase. \u00a9 2005 Elsevier Ltd. All rights reserved.",

        "abstract": "Free and Easy Wanderer Plus (FEWP) is a well-known traditional Chinese medicine that has been shown to be effective in treating various mood disorders. The purpose of the present study was to determine whether FEWP could ameliorate stress-associated behavior in rats. Following the exposure to enhanced single prolonged stress (ESPS) paradigm, consisting of 2-hr constraint, 20-min forced swimming, ether-induced loss of consciousness, and an electric foot shock, animals were administered orally with FEWP (2.5, 5, or 10 mg/kg daily) or vehicle for 2 weeks. Animals were then tested in the open field, elevated plus-maze, and Morris water maze. ESPS exposure resulted in pronounced anxiety-like behavior, without impairing locomotor activity, as indicated by significant decreases of time spent and number of entries into open arms in the elevated plus-maze test, and unaltered distance traveled in the open field test compared to unexposed animals. ESPS-exposed animals also displayed marked cognitive impairments, with significant increases of distance traveled and the escape latency to the underwater platform, and a striking decrease of time spent in the target quadrant with and without the removal of the platform in the water maze test. However, repeated treatment with FEWP, particularly at higher doses, reversed the aforementioned behavioral values in the elevated plus-maze and water maze tests to the levels similar to unexposed animals. These results indicate that FEWP possesses anxiolytic and cognition-improving effects and may be an effective herbal preparation for the treatment of stress-associated conditions, such as posttraumatic stress disorder (PTSD). \u00a9 2009 Elsevier Inc.

        "abstract": "Objective: To assess the efficacy and safety of long-acting injectable risperidone (LAIR) in patients with schizophrenia. Methods: A total of 48 schizophrenia patients with symptoms lasting over 1 year were collected, and treated with LAIR and oral risperidone tablets for 4 weeks followed by LAIR alone for 8 weeks. The efficacy was evaluated using the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression Scales for severity (CGI-S) and Personal and Social Performance Scale (PSP). The adverse reactions were evaluated using the TESS, AIMS, BARS Scale, laboratory indexes, vital signs, medical and electrocardiographic examinations. Results: After treatment with LAIR alone for 8 weeks, the total effective rate (PANSS reduced \u2265 30% ) was 80.5%; mean reduction in CGI-S was 2.1; the rate of patients with increased PSP \u2265 7 was 85.32%. LAIR mildly affected weight-gain profile and caused less extrapyramidal reactions. There were no significant changes in vital signs, medical and electrocardiographic examinations, but 7.0% patients had an increase in glutamate pyruvate transaminase (GPT) activity. Conclusions: LAIR significantly improves the social performance in patients with schizophrenia, and can be used as the first line antipsychotic for monotherapy.",

        "abstract": "On July 29, 2007, a severe coalmine-flooded disaster occurred in central China and 69 miners were trapped in an about 1400. m underground coal pit. Fortunately, all of them were rescued after 75. h of the ordeal. At 3 and 6. months after the disaster, psychopathological profiles, plasma levels of cortisol and adrenocorticotropic hormone (ACTH) were evaluated in 48 survivors for posttraumatic stress disorder (PTSD) and comorbid symptoms. Magnetic resonance imaging (MRI) study was performed at 6. months. The prevalence of PTSD was 35.4% (17/48) at 3. months and 31.3% (15/48) at 6. months post-disaster, with high rates of comorbid symptoms. Risk factors for PTSD included previous traumatic experience, less than 5. years of being a miner, in an extremely exhausted or sick during the disaster, poor interpersonal relationship and poor sleep quality experienced before the disaster. Mean plasma cortisol levels at 6. months, but not at 3. months, were significantly higher in PTSD-positive subjects than the negative, and positively correlated with the severity of several comorbid symptoms. Either whole or regional brain volumes of PTSD-positive subjects were not significantly different from PTSD-negative subjects, but PTSD subjects had significantly reduced fractional anisotropy values in the right posterior cingulum and bilateral hippocampal body compared to subjects without PTSD. These results suggest that traumatic exposure in severe coalmining disasters results in considerable psychological consequences, with highly prevalent PTSD and comorbid symptoms, which are associated with previous traumatic experience, shorter-length underground services, and poor interpersonal relationships and sleep quality experienced before the disaster. Baseline cortisol level may be a useful biological predictor for different phases of the development of PTSD. The aberrant connectivity of the hippocampus and the cingulum may represent an early pathological response to trauma exposure. \u00a9 2009 Elsevier Ltd.",

        "abstract": "Background The relationship between age at onset (AAO) and major depression (MD) has been studied in US, European and Chinese populations. However, larger sample studies are needed to replicate and extend earlier findings. Methods We re-examined the relationship between AAO and the clinical features of recurrent MD in Han Chinese women by analyzing the phase I (N=1848), phase II (N=4169) and total combined data (N=6017) from the CONVERGE project. Linear, logistic, multiple linear and multinomial logistic regression models were used to determine the association of AAO with continuous, binary and categorical variables. Results The effect size of the association between AAO and clinical features of MD was quite similar in the phase I and phase II samples. These results confirmed that MD patients with earlier AAO tended to suffer more severe, recurrent and chronic illness and cases of MD with earlier AAO showed increased neuroticism, greater family history and psychiatric comorbidity. In addition, we showed that earlier AAO of MD in Han Chinese women was associated with premenstrual symptoms, postnatal depression, a highly authoritarian or cold childhood parental rearing style and a reduced probability for having melancholia. Limitations Data were collected retrospectively through interview and recall bias may have affected the results. Conclusions MD with earlier AAO in Han Chinese women shows a distinct set of clinical features which are similar to those reported in Western populations. \u00a9 2014 Published by Elsevier B.V.",

Through adopting wiper trip and improving drilling fluid density, the effect of electric - log was still poor. In order to solve problem, a special sealing fluid with low salinity, high electrolyte solubility and good temperature resistance is developed and it was injected into the slacking off section to control effectively the plastic deformation of gypsum salt bed. Practice proved the method is more convenient and effective than the method of improving drilling fluid density.",

The DSC modulus was assembled according to the way of future industrial production, with the size of 15 cm \u00d7 20 cm, and the active area is ratio 65%. Temperature range from -40 to 60\u00b0C was tested in this paper. The different solvents in the electrolyte, including acetonitrile (ACN), valeronitrile (VN), 3-methoxypropionitrile (MPN) and its mixture solution in the electrolyte, were also investigated in this paper.",

        "abstract": "Moina mongolica Daday, which appears to be the only halophilic species of Moina in the old world, distributes from north Africa, across the Middle East and the Central Russia, Aral Sea, Spain. It is a new record of Cladocera in China. Dalian Fisheries University has initiated a saline water research program including its autecology, reproductive biology, feeding ecology and perspective as live food for marine fish larviculture. However, the effect of light on the ingestion capacity is not reported. A direct counting method was used to estimate the ingestion capacity of Moina mongolica Daday at different light intensity (8500 lx, 7000 lx, 5000 lx, 2000lx and 500 lx), photoperiods (L:D 0:24, 6:18, 12:12, 18:6 and 24:0), spectra (blue light and green light) and common light intensity in laboratory. The experimental animals collected from Lake Xiaochi in Yuncheng city, Shanxi Province in China, in 1982, were cultured in marine water at laboratory for 22 years, during which they were fed by Chlorella sp. . The experiment was carried out in illumination culture chambers (HPG-400). Water temperature is 25\u00b11\u00b0C. The salinity is about 32. pH value is 8. 2. The results showed that, the ingestion capacity of M. mongolica at light intensity 7000 lx was highest. The clearance rates of adult and young animal were 0.528 \u00b1 0.009 and 0.495 \u00b1 0.014 ml/ (ind\u00b7h), respectively) and grazing rates were 1.113 \u00b1 0.015 and 1.051 \u00b1 0.008 \u03bcC/(ind\u00b7h), respectively. At the blue light, the clearance rates and the grazing rates of M. mongolica is better than those at the green group. The ingestion capacity of adult M. mongolica fed on Chlorella sp. was the best in L:D= 12:12 group. The clearance rates of adult and young animal were 0.461 and 0.355 ml/(ind\u00b7h), and grazing rates were 1.242 and 1.005\u03bcC/(ind\u00b7h). The worst ingestion capacity was observed in L:D = 0:24 group. The clearance rates of adult and young M. mongolica were 0.070 and 0.050 ml/ (ind\u00b7h), respectively.

Methods: Eighty-eight Wistar rats were randomly divided into normal control group(NC, n = 8), scald group(S,gavage of distilled water after full-thickness scald, n=40), therapeutic group(T, gavage of rheum solution after full-thickness scald, n=40). The blood samples were harvested from inferior vena cava at 6, 12, 24, 48, 72 post scald hours (PSH) to determine the levels of MTL,SS, SP and VIP with radioimmunoassay. Results: (1) The levels of MTL and SP were (198 \u00b1 28),(61 \u00b1 10) ng/L, respectively, in NC group. The levels of MTL and SP in S group reached their minimum values [(110 \u00b1 15), (30 \u00b1 5)ng/L, respectively]at 6 PSH, then ascended slowly, peaked at 72 PSH but still lower than those in NC group (P < 0.05). The levels of MTL and SP slowly descended in T group, reached normal levels at 48 PSH, and obviously higher than those in NC group at 72 PSH[(232 \u00b1 32), (73 \u00b1 11) ng/L,respectively, P < 0.05], which were higher than those in S group at 6-72 PSH. (2) The levels of VIP and SS were (35 \u00b1 6), (30 \u00b1 5) ng/L, respectively, in NC group. The levels of VIP and SS in S group were (70 \u00b1 12), (49 \u00b1 9)ng/L at 6 PSH, which were obviously higher than those in NC group(P < 0.01), then descended slowly, but still higher than normal level at 72 PSH (P < 0.05). The levels of VIP and SS in T group ascended slowly, reached the normal level at 48 PSH, which were lower than those in S group at each time points, and VIP reached peak value at 12 PSH.

        "abstract": "Objective: To observe expressions of glucose-regulated protein (GRP78) and caspase-12 in nervous system-interstitial cells of Cajal (ICC) in smooth muscle in colonic wall in rats with scald injury, as well as their relevant ultrastructural changes, so as to probe the possible mechanisms of dynamic damage in murine colon after a scald injury. Methods: Fifty healthy Sprague-Dawley rats were randomly divided into scald (n = 40) and control (n = 10) groups. Rats in scald group were inflicted with 3096 TBSA full-thickness scald, and received an intraperitoneally injection of Ringer lactate solution (50 mg/kg) for resuscitation, while those in control group had similar treatment with the exception of scald. Rats in control group and scald group were sacrificed at 3, 6, 12, 24 post scald hour (PSH, 10 rats at each time point) for collection of 4 cm of colonic tissue, 5 cm proximal to the cecum. A segment of colonic wall, 1 cm in length, was obtained from the middle of the harvested segment of colon, and it was fixed with 396 glutaraldehyde or 1096 formaldehyde. The samples fixed with glutaraldehyde were used to observe ultrastructural alterations under transmission electron microscope, while that with formaldehyde were used to observe expressions of GRP78 and caspase-12 in colonic wall by immunohistochemical assay. Results: The colonic smooth muscle cells of rats in control group showed regular arrangment, their organelles were abundant, nucleus centrally located, euchromatin distributed evenly with more abundant mitochondrial cristae and less smooth endoplasmic reticulum, neuronal organelles were abundant in intermuscular plexus, and ICC could be seen in the neighborhood of neurons. The colonic smooth muscle cells appeared in irregular and disordered manner in scald group, perinuclear space was widened, intercellular vacuoles were observed, mitochondria showed vacuolation degeneration with dissolved and condensed cristae, rough endoplasmic reticula were dilated with partial dissolution, and perinuclear cytoplasm of ICC was obviously decreased. The expression of GRP78 was increased in scald group at 3, 6, 12 PSH (4.3 \u00b1 0.9, 6.0 \u00b1 0.7, 4.8 \u00b1 1.1 score) as compared with that in control group (2.4 \u00b1 0.7 score, P < 0.05). The expression of caspase-12 in scald group at 6, 12, 24 PSH was higher than that in control group (P < 0.05). GRP78 was consistantly expressed in cytoplasm in control group, while in scald group, it mainly appeared in mucosa, myenteric plexus, and stromal cells, but only moderately or lightly expressed in smooth muscle cells. The expression of GRP78 was positive in scald group at 3, 6, 12 PSH, strongly positive at 6 PSH, and it was also expressed in cytoplasm in control group. The expression of caspase-12 in scald group was not obviously positive at 3 PSH, and weakly positive at 6, 24 PSH, but strongly positive at 12 PSH, while no expression was shown in control group. Conclusions: Marked pathological changes are observed in enteric nervous system-interstitial cells of Cajal-smooth muscle in rats with severe scald injury. It may be related with cellular injuries induced by caspase-12 apoptotic pathways through activated endoplasmic reticulum stress.",

Studies demonstrated that recombinant human epidermal growth factor (rhEGF) has accelerated effect on epidermal regeneration. OBJECTIVE: To observe the effect of rhEGF on wound healing of skin donor site. METHODS: A total of 32 cases needs wound healing by skin grafting were collected, including 18 males and 14 females. The 32 skin graft donor site wounds were randomly divided into control and treatment groups. In the treatment group, the absorbent gauze was sprinkle soaked with rhEGF (15 mL/ramus, 2 000 IU/mL) and covered the donor site, twice per day. In the control group, donor site was covered by physiological saline gauze and wrapped with dressing, twice per day. After 48 hours, semi-exposed therapy was performed. The healing time of wounds, the systemic and local adverse reactions of patients and blood routine examination and renal function detection prior to and after treatment were observed. RESULTS AND CONCLUSION: The healing time of wound in the rhEGF treatment group was shorter than that in the control group with significant differences (P < 0.01). No Adverse events or side effects were observed in the rhEGF treatment group. rhEGF can shorten wound healing time, reduce scar hyperplasia, and accelerate epithelization at the graft donor.",

        "abstract": "Objective: To study the influence of serum from scalded rats on the cytoskeleton of colonic smooth muscle cells (CSMC) of rats cultured in vitro, and to probe the possible mechanism of gastrointestinal motility disorder after burn. Methods: CSMC isolated from healthy adult Wistar rat were cultured and divided into scald serum group (SS) and normal serum group (NS) according to the random number talbe. Two normal Wistar rats were used, one of which was inflicted with deep partial-thickness scald. Serum was obtained from blood collected from these two rats respectively and diluted to 20% in concentration. Serum from scald and normal rats were respectively added to the culture of CSMC in SS and NS groups. The expression of actin and the relative content of \u03b2-tubulin in CSMC was respectively determined with flow cytometry and Western blot at post treatment hour (PTH) 1 , 3, 6, and 12 (with 10 samples in each group at each time point). Data were processed with t test. Results: Fluorescence intensity of actin in SS group at PTH 1,3,6, and 12 was respectively 59 \u00b1 4 , 26 \u00b1 6 , 39 \u00b1 6 , and 42 \u00b1 6 , all significantly lower than those in NS group (95 \u00b1 10, 91 \u00b1 10, 102 \u00b1 9, and 97 \u00b1 9, with t value respectively 10.528, 18.069, 18.748, 16.647, P <0.05 or P <0.01). In SS group, the fluorescence intensity decreased to the nadir at PTH 3, and then increased persistently at PTH 6 and 12. (2) Relative content of \u03b2-tubulin in SS group at PTH 1 , 3, 6, and 12 was respectively 14.44 \u00b1 0.26, 8.61 \u00b1 0.19, 11.76 \u00b1 0.31, and 12. 13 \u00b1 0.29, all significantly less than those in NS group (22. 37 \u00b1 1.15 , 21.87 \u00b1 1.79, 23.24 \u00b1 1.55, and 21.99 \u00b1 2.02, with t value respectively 21.176, 23.365, 23.000, 15.273, P values all below 0.01). In SS group, the relative content of \u03b2-tubulin decreased to the nadir at PTH 3 and increased slowly at PTH 6 and 12. Conclusions The reduction of CMSC content which has the tendency of increasing later, can he attributed to the influence of scald serum in initial stage. This may be related to the tolerance and adaptation to scald serum and self-repair of CMSC.",

        "abstract": "Distraction osteogenesis requires a long consolidation period and has a low but real failure rate. Bone morphogenetic proteins (BMPs) accelerate bone deposition in fractures and critical-sized bone defects. Vascular endothelial growth factor (VEGF) is a promising reagent for inducing angiogenesis, and is an essential coordinator of extracellular matrix remodeling, angiogenesis, and bone formation in the growth plate. However, their effects on mandibular distraction osteogenesis are unknown. We investigated the effect of local delivery of plasmid pIRES-hBMP-2-hVEGF165 into a distraction area by electroporation-mediated approach.A New Zealand rabbit model were used. Activation of the device was commenced after 3 days of latency period and proceeded at the rate of 0.8 mm per day for 7 days. After the completion of activation, the rabbits were randomly divided into 5 groups: group A: recombinant plasmid 2 \u03bcg (0.1 \u03bcg/\u03bcL) pIRES-hVEGF165-hBMP2 was injected into the distraction area after the completion of activation; group B: recombinant plasmid pIRES-hBMP2 was injected into the distraction area; group C: recombinant plasmid pIRES-hVEGF165 was injected into the distraction area; group D: pIRES was injected into the distraction area, and group E: normal saline was injected into the distraction area. After injection every group used electroporation. Subsequently, the rabbits were examined by quantitative computed tomography, mechanical testing, and histomorphometric analysis.BMD of newly formed bone of the distraction area in groups A, B, and C were remarkably higher than those of groups D and E at different times (P < 0.001). At 4 and 8 weeks of consolidation, the crushing strength of 3 points of the newly formed bone in group A was remarkably higher than those of groups B, C, D, and E (P < 0.01). The results demonstrated statistically remarkable increase in regenerated bone in the gene-transfected groups.Electroporation-mediated transfecting recombinant plasmid pIRES-hVEGF165-hBMP2 could produce a satisfactory proceeding of osteogenesis and calcification, which surpassed that of the control group. This finding indicates that a combination of VEGF and BMP may make osteogenesis and angiogenesis appear at the same time. Furthermore, it may magnify the effect of single growth factor, and promote growth and reparative process of bone. Copyright \u00a9 2012 by Lippincott Williams & Wilkins.",

Based on previous study, the authors used New Zealand rabbits bilateral mandibular distraction model and used electroporation mediate gene therapy at different time, to explore the optimal time for gene therapy and obtain a better effect. METHODS: Forty-eight New-Zealand rabbits were used; after accomplished osteotomy and implant distraction devices on mandible bilaterly, the rabbits were randomly divided into 4 groups: groups A, B, and C were transfected recombinant plasmids pIRES-hBMP2-hVEGF165 via electroporation-mediated approach at latency period, distraction period, and consolidation period, respectively. Group D is a control group, only distracted without gene transfection. After 3 days of latency period, the device was activated at the rate of 1 mm per day for 10 days. Three rabbits of each group were sacrificed at 1, 2, 4, and 8 weeks of consolidation, respectively. The mandibles were harvested; the left was subject to radiograph examination for bone healing, and quantitative computed tomography detect for the bone mineral density (BMD) of newly formed bone in the distraction gap. The biomechanical properties of the new generation bone at the fourth and eighth weeks of consolidation of each group were detected using 3-point bending test. RESULTS: The BMD and the stiffness of newly formed bone increased with the pass of the consolidation time in each group. After 1 week of consolidation, there is no significant difference of BMD among groups A, B, and C. However, the BMD of groups A, B, and C is higher than that of group D. After 2, 4, and 8 weeks of consolidation, the BMD of group B is significantly higher than those of groups A, C, and D. The biomechanical parameters are also higher in group B than those of groups A, C, and D after 4 and 8 weeks of consolidation. CONCLUSIONS: It is better to transfect gene at distraction period than at other stages of DO; in this way, we can obtain more remarkable effect on new bone formation. It suggests that the distraction stage is the optimal time for gene therapy. Copyright \u00a9 2013 by Mutaz B. Habal, MD.",

In the whole study group, XPD Arg156Arg was not associated with risk of lung cancer. In stratified analyses, the variant A-allele of XPD Arg156Arg was associated with increased risk of adenocarcinoma of lung (AA/AC versus CC; adjusted OR=1.65; 95% CI=1.09-2.50) (P=0.02). Furthermore, the presence of one or two variant A-alleles was associated with increased risk for lung cancer (OR=2.49; 95% CI=1.10-5.64) (P=0.03) and adenocarcinoma of lung (OR=5.60; 95% CI=1.52-20.56) (P=0.005) among never-smokers only. These results suggest a possible gene-environment interaction. This is the first study to report a significant association of XPD Arg156Arg with risk of lung cancer. \u00a9 2004 Elsevier Ireland Ltd.

This study was designed to examine whether ERCC1 Asn118Asn (G19007A) polymorphism, which has been associated with risk of some cancers among Caucasians, may be associated with risk of lung cancer in a Chinese population. ERCC1 Asn118Asn (G19007A) genotypes were determined in DNA samples from 151 cases and 143 controls. The distribution of genotypes between cases and controls was not associated with an increased risk of lung cancer (AA versus GG: adjusted OR (odds ratio) = 1.41, 95% CI (confidence interval) = 0.76-2.59; AG versus GG: adjusted OR = 0.78, 95% CI = 0.47-1.29; and AA+AG versus GG: adjusted OR = 0.93, 95% CI = 0.73-1.19). The frequency A (0.20) of the A-allele was significantly lower among these Chinese controls than in the Caucasian control populations (A = 0.54-0.65) (All P < 0.001). No statistically significant effects of age, histological subtype or smoking were found. These findings suggest that ERCC1 Asn118Asn (G19007A) polymorphism may play a limited role for lung cancer in this Chinese population. \u00a9 2006 Elsevier Inc. All rights reserved.",

The present study measured differences in expression of NMDA receptor subunits NR1, NR2A, and NR2B in memory-related brain regions of rats who underwent different doses of lead exposure. Results demonstrated decreased NR1, NR2A, and NR2B subunit expressions in some memory-related brain areas. The inhibitory effect of 4.8 mmol/L lead exposure on hippocampal NR2B was most significant, although NR2A expression also significantly decreased following 14.4 mmol/L lead exposure. There was no difference in NR1 expression following exposure to < 4.8 mmol/L lead, although the inhibitory effect of 19.6 mmol/L lead exposure was strongest for NR1 expression in the hippocampus. Inhibitory avoidance test results revealed that greater concentrations of lead exposure resulted in decreased learning and memory. Therefore, lead toxicity was dependent on NMDA receptor subunit composition, and NR1, NR2A, and NR2B expressions were associated with time and concentration of lead exposure.",

No significant deviations from Hardy-Weinberg equilibrium could be found for all loci. Allele frequencies in the Xibo population ranged from 0.001 to 0.507. Among all the 6 loci, D16S539 had the highest polymorphism (PIC = 0.8632), whereas TPOX had the lowest (PIC = 0.5179). A phylogenic tree was constructed using Poptree 2 software. In the phylogenic tree, Xibo population has a distant relationship with the other populations. \u00a9 2011 Elsevier B.V.",

PPP1R13L and CD3EAP on chromosome 19q13.3 are mainly involved in apoptosis and transcription. PPP1R13L and CD3EAP variants may be associated with cancer risk. We addressed the effects of variants/haplotypes of PPP1R13L rs1970764 and CD3EAP rs967591 and rs735482 on susceptibility of lung cancer among nonsmoking Chinese women. A hospital-based case-control study consisted of 79 lung cancer cases and 108 cancer-free controls matched by age (\u00b13years), gender, ethnicity and lifetime never-smoking. Genotyping and statistical analysis were performed by using the method of ligase detection reaction coupled with polymerase chain reaction (LDR-PCR) and SHEsis program and SPSS software. The presence of variant A-allele for CD3EAP rs967591 was associated with increased lung cancer risk [GA versus GG, OR (95% CI)=2.53 (1.16-5.48), P=0.02 and GA+AA versus GG, OR (95% CI)=2.46 (1.16-5.20), P=0.02].

The observed heterozygosity(HO)values of these 19 STR loci ranged from 0.600 (D3S1358) to 0.914 (D18S51), the expected (HE) ranged from 0.615 (TPOX) to 0.876 (D16S1043). The power of discrimination (PD) values were found to range from 0.793 (TPOX) to 0.950 (D16S1043) and the probability of exclusion (PE) varies between 0.291 (D3S1358) and 0.825 (D18S51 and Penta E). Among all the 19 loci, D16S1043 had the highest polymorphism (PIC=0.860), whereas TPOX had the lowest (PIC=0.550). For the 19 loci, the combined power of discrimination and the combined probability of exclusion are 0.9999999999999999999942 and 0.999999996777, respectively.

Primary splenic lymphocytes were exposed to DEHP/MEHP. ELISA and Western blotting were used to detect proteins. Confocal-microscopy was used to examine nuclear translocation. Nuclear factor of activated T cells (NFAT) DNA binding activity was examined by electrophoretic mobility-shift assay. DEHP significantly increased IL-4 and interferon gamma (IFN-\u03b3) level, and reduced Th1/Th2 ratio (reflected by IFN-\u03b3/IL-4) with 5 \u03bcg/L Concanavalin A (ConA) treatment. While MEHP reduced Th1/Th2 ratio (represented by IFN-\u03b3/IL-6). IL-4 mRNA was significantly increased by DEHP but not by MEHP after PMA and Ion treatment. DEHP significantly inhibited NFATp protein in cytosol and nucleus. DEHP augmented nuclear translocation of NFATc in transfected EL4 cells and NFAT DNA-binding activity. DEHP-mediated enhancement of calcium-dependent phosphatase calcineurin (CaN) protein, and NFAT and IL-4 expression were abrogated by calcium antagonist verapamil and CaN inhibitor tarcolimus. Ca ",

        "abstract": "Background: In view of their high level of variability, autosomal short tandem repeats (STRs) are very useful as markers in the disciplines of forensic and population genetics studies. Aim: To investigate the diversity distributions of allelic frequencies of 15 loci from a sample from the Chinese Xibe ethnic group in Liaoning. Subjects and methods: Fifteen STR loci for 150 unrelated Xibe individuals from Liaoning, China were amplified simultaneously in a fluorescence-based reaction using a 2720 Thermal cycler (ABI). Separation and detection of the amplified product were conducted with the Li-COR 4300 DNA Analyzer. Results: In total, 117 alleles were observed, with the corresponding allele frequencies ranging from 0.001 to 0.507. D18S51 had the highest polymorphism (PIC=0.840) among all 15 STR loci, whereas TPOX had the lowest (PIC=0.590). The power of discrimination ranged from 0.801 for TH01 locus to 0.957 for D18S51 locus, whereas the power of exclusion ranged from a minimum 0.316 for TPOX locus to a maximum 0.720 for D21S11 locus. The phylogenetic tree established among worldwide populations showed that the Xibe population is far from other populations. Conclusion: Databases for the 15 STR loci will be useful for personal identification and paternity tests in the Xibe population and for the establishment of phylogenetic relationships between populations. \u00a9 2014 Informa UK Ltd.",

        "abstract": "The pathogenesis of the severe acute respiratory syndrome (SARS), a newly emerging life-threatening disease in humans, remains unknown. It is believed that the modulation of apoptosis is relevant to diseases that are caused by various viruses. To examine potential apoptotic mechanisms related to SARS, we investigated features of apoptosis induced by the SARS-associated coronavirus (SARS-CoV) in host cells. The results indicated that the SARS-CoV-induced apoptosis in Vero cells in a virus replication-dependent manner. Additionally, the downregulation of Bcl-2, the activation of casapse 3, as well as the upregulation of Bax were detected, suggesting the involvement of the caspase family and the activation of the mitochondrial signaling pathway. Although there is a positive correlation between apoptosis and virus replication, the latter is not significantly blocked by treatment with the caspase inhibitor z-DEVD-FMK. These preliminary data provide important information on both the pathogenesis and potential antiviral targets of SARS-CoV. \u00a9 Mary Ann Liebert, Inc.",

In order to improve the expression of the norovirus capsid, we re-designed and artificially synthesized the full-length norovirus capsid genes by adopting the codons preferentially used in insect cells without any changing of the amino acid sequences. The codon optimized capsid genes of Norovirus GGII1, GGII3, GGII4 and GGII7 were respectively expressed in insect cell Sf9 using baculovirus vector. The results showed that, compared to the wild type, the expression levels of the optimized genes were remarkably increased. The assembly of norovirus-like particles was observed in the Sf9 cells infected with the recombinant baculovirus expressing the capsid protein. The recombinant capsid expression peaked at 72h post infection of the recombinant baculoviruses. The results obtained in the present work will lay a foundation for the development of the immunological diagnostic reagents as well as vaccines for human caliciviruses.",

        "abstract": "Norovirus (NV) is a major cause of acute, epidemic nonbacterial gastroenteritis in individuals of all ages. The immunological mechanism of NV infection and the approaches used to prevent infection remain to be elucidated. In this study, the specific immune responses of BALB/c mice were assessed following intranasal immunization with a recombinant adenovirus vector expressing the genogroup II4 (GGII/4) norovirus capsid protein. Analysis of IgM, IgG, and IgA antibodies specific for the recombinant virus-like particles (VLPs) of NV demonstrated that a high level of humoral immunity developed following immunization. Mucosal immune responses were also detectable in stool, intestinal homogenates, lung homogenates, and lung lavage samples. Specific cellular immune responses were observed in NV VLPs-restimulated splenocytes by ELISPOT and Th1/Th2 cytokine cytometric array (CBA). Serum IgG subclass analysis showed that a balanced Th1- and Th2-like cellular immune response was induced in BALB/c mice following immunization with recombinant adenovirus. These findings demonstrate that the intranasal immunization of a recombinant adenovirus expressing the NV capsid protein is an efficient strategy to stimulate systemic, mucosal, and cellular Th1/Th2 immune responses in mice, and could serve as a novel approach for designing NV vaccines. \u00a9 2007 Elsevier Ltd.

        "abstract": "Background: Noroviruses (NoVs) are a major cause of acute gastroenteritis in children, but prevalence and circulation of NoVs in China have not been well characterized. Objectives: To determine the dominant circulating NoV genotypes and strains associated with pediatric cases of acute gastroenteritis in Beijing, China. Study design: Fecal samples were obtained from 1126 children affected with acute gastroenteritis in Beijing from March 2004 to November 2007. NoV RNA was amplified, sequenced, and phylogenetically analyzed to determine the dominant circulating genotypes and strains. Results: NoVs were detected in 8.88% of patients, GII.4 being the dominant genotype. Ehime/05-30 was the dominant strain during 2004-2005, whereas 2006b dominated during 2006-2007. The homology of nucleotide and amino acid sequences among full-length VP1 of 15 randomly selected NoV strains was 91.6-99.6% and 94.5-99.6%, respectively. Recombination between NoV genotypes was frequent among the isolates. Conclusions: The predominant circulating genotype of NoV infections in Beijing is GII.4, but the dominant strains of this virus responsible for gastroenteritis epidemics are evolving rapidly. A global surveillance network may be needed to identify trends in molecular evolution of NoVs for prevention of future epidemics. \u00a9 2008 Elsevier B.V. All rights reserved.",

        "abstract": "Background. Avian influenza virus H5N1 is a major concern as a potential global pandemic. It is thought that multiple key events must take place before efficient human-to-human transmission of the virus occurs. The first step in overcoming host restriction is viral entry which is mediated by HA, responsible for both viral attachment and viral/host membrane fusion. HA binds to glycans-containing receptors with terminal sialic acid (SA). It has been shown that avian influenza viruses preferentially bind to \u03b12,3-linked SAs, while human influenza A viruses exhibit a preference for \u03b12,6-linked SAs. Thus it is believed the precise linkage of SAs on the target cells dictate host tropism of the viruses. Results. We demonstrate that H5N1 HA/HIV pseudovirus can efficiently transduce several human cell lines including human lung cells. Interestingly, using a lectin binding assay we show that the presence of both \u03b12,6-linked and \u03b12,3-linked SAs on the target cells does not always correlate with efficient transduction. Further, HA substitutions of the residues implicated in switching SA-binding between avian and human species did not drastically affect HA-mediated transduction of the target cells or target cell binding. Conclusion. Our results suggest that a host factor(s), which is yet to be identified, is required for H5N1 entry in the host cells.",

        "abstract": "Background: Human adenovirus serotype 41 (Ad41) is a natural pathogen of the digestive tract and can cause gastroenteritis. There has been interest in reconstructing Ad41 as a gene delivery vector targeting the gastrointestinal tract, which is hampered by its fastidiousness. Methods: An Ad41 E1B55K-transduced 293 cell line (293E12) was established as the packaging cell line. A backbone plasmid (pAdbone41) and a shuttle plasmid (pSh41-CMV) were constructed based on the Ad41 genome. Replication-defective adenovirus (Ad41-GFP) was rescued in 293E12 after being transfected with the linearized adenoviral plasmid, which was generated by homologous recombination of pAdbone41 and the shuttle plasmid carrying the GFP gene in Escherichia coli strain BJ5183. The packaging ability of 293E12, the stability of the Ad41-GFP genome and the acid-resistant property of Ad41-GFP were all investigated. Results: A 293E12 cell could produce approximately 9000 viral particles of Ad41-GFP, which is close to the amount in the control virus (Ad5-GFP) amplified in one 293 cell. Ad41-GFP contained a genetically stable genome after being passaged eight times in 293E12 cells. More significantly, Ad41-GFP was more resistant to acid exposure than Ad5-GFP. It retained almost complete viability when exposed to hydrochloric acid with a pH value of 2 for 30 min, whereas Ad5-GFP lost 99% of its viability under the same conditions. Ad41-GFP was also more tolerant to treatment with artificial digestive fluid. Conclusions: An Ad41 vector system was successfully constructed, which consisted of the backbone plasmid, shuttle plasmid and packaging cell line 293E12. This system can be utilized to generate genetically stable and acid-resistant recombinant Ad41 carrying any gene of interest. Copyright \u00a9 2008 John Wiley & Sons, Ltd.",

        "abstract": "The genus Helice is comprised of four species, H. formosensis, H. latimera, H. tientsinensis, and H. tridens. A recent molecular analysis identified H. formosensis and H. tientsinensis as junior synonyms of H. latimera. We used three mitochondrial and two nuclear genes to further delineate species boundaries in Helice and to add to knowledge of the historical biogeography of the genus. The molecular data revealed deep divergences between the H. formosensis-latimera-tientsinensis complex and H. tridens. Clear genetic separations with incomplete lineage sorting and convincing morphological divergences were detected among H. formosensis, H. latimera, and H. tientsinensis, and a coalescence analysis revealed negligible gene flow among these species, except for weak unidirectional gene flow from H. formosensis to H. latimera. The estimated divergence time of 1.42-1.92 Ma between the H. formosensls-latimera-tientsinensis complex and H. tridens is consistent with the opening of the Tsushima/Korea Strait (1.71-1.52 Ma). The divergence time (-22-730 ka) among H. formosensis, H. latimera, and H. tientsinensis indicates that the Taiwan Strait acted as a biogeographic barrier during major falls In sea level during the Pleistocene. Our findings indicate that H. formosensis, H. latimera, and H. tientsinensis are valid species, and that straits (Tokara Strait, Tsushima/Korea Strait, and Taiwan Strait), the Okinawa Trough, and currents (Kuroshio Current, Tsushima Current, and Taiwan Strait Warm Current) have acted as geographic barriers resulting in allopatric speciation among onshore marine animals in the northwestern Pacific. \u00a9 2009 Zoological Society of Japan.",

However, the ability of such regimens to provide immunity against norovirus (NV), an important cause of acute epidemic gastroenteritis worldwide, has never been assessed. In this study, we analyzed NV-specific humoral, mucosal, and cellular immune responses following intranasal immunization with the recombinant adenovirus expressing the NV GGII4 capsid protein (rAd) prime-NV virus-like particle (VLP) boost, VLP prime-rAd boost, or repeated NV VLP regimens. Our results show that mice primed with rAd and boosted with VLP had stronger humoral, mucosal, and interferon-\u03b3 responses than those immunized with VLP prime-rAd boost or VLP alone. These results demonstrate that adenovirus prime-VLP boost vaccination is an effective strategy for induction of immune responses against NV and is a promising strategy to improve current VLP-based NV vaccine development. \u00a9 2009 Elsevier Ltd.

        "abstract": "Human astroviruses (HAstVs) have been recognized as one of the major causes of acute gastroenteritis in children. To provide more insight into the prevalence of HAstV gastroenteritis in China, 664 fecal samples were collected from children affected with acute gastroenteritis in Beijing from March 2005 to November 2007. The samples were analyzed genetically. All eight serotypes (genotypes) of HAstVs were screened using RT-PCR assays targeting the ORF2 region in the study. The assays detected HAstVs in 52 (7.8%) of the patients, with HAstV-1 (50/52) being the dominant genotype during the study period. Two minor genotypes, HAstV-6 and HAstV-3, were also detected. Partial sequencing of the 50 HAstV-1 strains showed that the homology of the nucleotide sequence of the ORF1a region between these strains was 88.4-100%, whereas the homology of the amino acid sequences was 95.6-100%. In the ORF2 partial region, the nucleotide identities ranged from 91.5% to 100%, and amino acid identities ranged from 97.3% to 100%. The identity of the whole genome sequence between four randomly examined HAstV-1 strains was 91-99%. No recombination events were observed in HAstVs in this study. The findings of this study will provide baseline data for HAstVs surveillance and control. \u00a9 2010 Wiley-Liss, Inc.",

Currently, eight HAstV genotypes have been identified and all but two (HAstV-6 and HAstV-7) have been fully sequenced. We here sequenced and analyzed the complete genome of a HAstV-6 strain (192-BJ07), which was identified in Beijing, China. Results. The genome of 192-BJ07 consists of 6745 nucleotides. The 192-BJ07 strain displays a 77.2-78.0% nucleotide sequence identity with other HAstV genotypes and exhibits amino acid sequence identities of 86.5-87.4%, 94.2-95.1%, and 65.5-74.8% in the ORF1a, ORF1b, and ORF2 regions, respectively. Homological analysis of ORF2 shows that 192-BJ07 is 96.3% identical to the documented HAstV-6 strain. Further, phylogenetic analysis indicates that different genomic regions are likely undergoing different evolutionary and selective pressures. No recombination event was observed in HAstV-6 in this study. Conclusion. The completely sequenced and characterized genome of HAstV-6 (192-BJ07) provides further insight into the genetics of astroviruses and aids in the surveillance and control of HAstV gastroenteritis. \u00a9 2010 Guo et al; licensee BioMed Central Ltd.",

        "abstract": "Background. Rotavirus (RV) is the main cause of severe gastroenteritis in children. An effective vaccination regime against RV can substantially reduce morbidity and mortality. Previous studies have demonstrated the efficacy of virus-like particles formed by RV VP2 and VP6 (VLP2/6), as well as that of recombinant adenovirus expressing RV VP6 (rAd), in eliciting protective immunities against RV. However, the efficacy of such prime-boost strategy, which incorporates VLP and rAd in inducing protective immunities against RV, has not been addressed. We assessed the immune effects of different regimens in mice, including rAd prime-VLP2/6 boost (rAd+VLP), VLP2/6 prime-rAd boost (VLP+rAd), rAd alone, and VLP alone. Results. Mice immunized with the VLP+rAd regimen elicit stronger humoral, mucosal, and cellular immune responses than those immunized with other regimens. RV challenging experiments showed that the highest reduction (92.9%) in viral shedding was achieved in the VLP+rAd group when compared with rAd+VLP (25%), VLP alone (75%), or rAd alone (40%) treatment groups. The reduction in RV shedding in mice correlated with fecal IgG (r = 0.95773, P = 0.04227) and IgA (r = 0.96137, P = 0.038663). Conclusions. A VLP2/6 prime-rAd boost regimen is effective in conferring immunoprotection against RV challenge in mice. This finding may lay the groundwork for an alternative strategy in novel RV vaccine development. \u00a9 2011 Zhou et al; licensee BioMed Central Ltd.",

        "title": "Large-scale seroprevalence analysis of human metapneumovirus and human respiratory syncytial virus infections in Beijing, China",
        "abstract": "Background: Human metapneumovirus (hMPV), a recently identified virus, causes acute respiratory tract infections (ARTIs) in infants and children. However, studies on the seroepidemeology of hMPV are very limited in China. To assess the seroprevalence of hMPV infection in China, we tested a total of 1,156 serum specimens for the presence of anti-hMPV IgG antibody in children and adults free of acute respiratory illness in Beijing, China by using hMPV nucleocapsid (N) protein as an antigen. As a control, we used the human serum antibody against the N protein of human respiratory syncytial virus (hRSV), the most important viral agent responsible for ARIs in children. Results: The seropositive rate for hMPV increased steadily with age from 67% at 1-6 mo to 100% at age 20. However, the rate dropped slightly between 6 mo and 1 yr of age. The seropositive rate for hRSV also increased steadily with age from 71% at 1-6 mo to 100% at age 20. In children aged six months to six years, the seropositive rates for the anti-hRSV IgG antibody were significantly higher than those for hMPV. Additionally, IgG antibody titers to hMPV and hRSV were significantly higher in adults than in young children. Consistent with the seropositive rates, the geometric mean titer of anti-hMPV IgG antibody was lower than that of anti-hRSV IgG antibody in children aged six months to six years. Conclusions: Our results indicate that similar to hRSV, exposure to hMPV is ubiquitous in the Beijing population. However, the seroprevalence of anti-hMPV IgG antibody is lower than that of hRSV in children between six months and six years old, which suggests a different number of repeat infections or a different response to infections. \u00a9 2011 Lu et al; licensee BioMed Central Ltd.",

        "abstract": "Subtype specificity of influenza A virus (IAV) is determined by its two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). For HA, 16 distinct subtypes (H1-H16) exist, while nine exist for NA. The epidemic strains of H1N1 IAV change frequently and cause annual seasonal epidemics as well as occasional pandemics, such as the notorious 1918 influenza pandemic. The recent introduction of pandemic A/H1N1 IAV (H1N1pdm virus) into humans re-emphasizes the public health concern about H1N1 IAV. Several studies have identified conserved epitopes within specific HA subtypes that can be used for diagnostics. However, immune specific epitopes in H1N1 IAV have not been completely assessed. In this study, linear epitopes on the H1N1pdm viral HA protein were identified by peptide scanning using libraries of overlapping peptides against convalescent sera from H1N1pdm patients. One epitope, P5 (aa 58-72) was found to be immunodominant in patients and to evoke high titer antibodies in mice. Multiple sequence alignments and in silico coverage analysis showed that this epitope is highly conserved in influenza H1 HA [with a coverage of 91.6% (9,860/10,767)] and almost completely absent in other subtypes [with a coverage of 3.3% (792/23,895)]. This previously unidentified linear epitope is located outside the five well-recognized antigenic sites in HA. A peptide ELISA method based on this epitope was developed and showed high correlation (\u03c7 ",

Methods: IL-2 signal peptide and human IgG Fc fragment were inserted into vector pCAGGS in turn to construct a fusion expression vector for human IgG Fc tag. H5 HA1 gene was cloned into fusion expression vector pCAGGS-F-IL-2/Fc for human IgG Fc tag, and the constructed recombinant plasmid was transiently transfected to 293T cells for expression of fusion protein. The expressed product was purified by one-step Protein G affinity chromatography. Results: Restriction analysis and sequencing proved that the fusion expression vector for human IgG Fc tag was constructed correctly, and HA1-Fc fusion protein, with a relative molecular mass of about 75 000, was successfully expressed in 293T cells in secretory form in 293T cells. The expression level of fusion protein in the cells 72 and 96 h after transfection reached peak values. The purified fusion protein reached a purity of more than 90%, and the recombinant protein content in cell culture was 1.63 \u03bcg/ml. Conclusion: The fusion expression vector for human IgG Fc tag was successfully constructed, and HA1-Fc fusion protein was expressed and purified, which laid a foundation of study on invasion and immune mechanism of influenza virus.",

        "title": "Evolutionary dynamics analysis of human metapneumovirus subtype A2: Genetic evidence for its dominant epidemic",
        "abstract": "Human metapneumovirus (hMPV) is a respiratory viral pathogen in children worldwide. hMPV is divided into four subtypes: hMPV_A1, hMPV_A2, hMPV_B1, and hMPV_B2. hMPV_A2 can be further divided into hMPV_A2a and A2b based on phylogenetic analysis. The typical prevalence pattern of hMPV involves a shift of the predominant subtype within one or two years. However, hMPV_A2, in particular hMPV_A2b, has circulated worldwide with a several years long term high epidemic. To study this distinct epidemic behavior of hMPV_A2, we analyzed 294 sequences of partial G genes of the virus from different countries. Molecular evolutionary data indicates that hMPV_A2 evolved toward heterogeneity faster than the other subtypes. Specifically, a Bayesian skyline plot analysis revealed that hMPV_A2 has undergone a generally upward fluctuation since 1997, whereas the other subtypes experienced only one upward fluctuation. Although hMPV_A2 showed a lower value of mean dN/dS than the other subtypes, it had the largest number of positive selection sites. Meanwhile, various styles of mutation were observed in the mutation hotspots of hMPV_A2b. Bayesian phylogeography analysis also revealed two fusions of diffusion routes of hMPV_A2b in India (June 2006) and Beijing, China (June 2008). Sequences of hMPV_A2b retrieved from GenBank boosted simultaneously with the two fusions respectively, indicating that fusion of genetic transmission routes from different regions improved survival of hMPV_A2. Epidemic and evolutionary dynamics of hMPV_A2b were similar to those of hMPV_A2. Overall, our findings provide important molecular insights into hMPV epidemics and viral variation, and explain the occurrence of an atypical epidemic of hMPV_A2, particularly hMPV_A2b. \u00a9 2012 Li et al.",

We re-examine phylogenetic relationships of Salangidae by including complete taxon sampling, based on seven nuclear loci and one mitochondrial gene using a multilocus coalescence-based species-tree method. Our results show a well-resolved phylogeny of Salangidae that does not agree with previous hypotheses. The topology test suggests that our hypothesis represents the most likely phylogeny. Using the inferred species-tree as criterion, we recombine the rank of subfamilies and genera in the Salangidae, and erect a new genus Neosalangichthys. Our revised classification of Salangidae is well supported by reinterpreting previously proposed diagnostic characters. Finally, re-defined synapomorphic characters are used to erect a key to the genera of Salangidae. \u00a9 2011 .",

        "abstract": "Background: Four species of human bocaviruses (HBoV1-4) have been identified based on phylogenetic analysis since its first report in 2005. HBoV1 has been associated with respiratory disease, whereas HBoV2-4 are mainly detected in enteric infections. Although the prevalence of HBoVs in humans has been studied in some regions, it has not been well addressed globally. Methodology/Principal Findings: Cross-reactivity of anti-VP2 antibodies was detected between HBoV1, 2, 3, and 4 in mouse and human serum. The prevalence of specific anti-VP2 IgG antibodies against HBoV1-4 was determined in different age groups of healthy individuals aged 0-70 years old in Beijing, China, using a competition ELISA assay based on virus-like particles of HBoV1-4. The seroprevalence of HBoV1-4 was 50%, 36.9%, 28.7%, and 0.8%, respectively, in children aged 0-14 years (n = 244); whereas the seroprevalence of HBoV1-4 was 66.9%, 49.3%, 38.7% and 1.4%, respectively, in healthy adults (\u226515 years old; n = 142). The seropositive rate of HBoV1 was higher than that of HBoV2, HBoV3, and HBoV4 in individuals older than 0.5 years. Furthermore, IgG seroconversion of HBoV1 (10/31, 32.3%), HBoV2 (8/31, 25.8%), and HBoV3 (2/31, 6.5%) was found in paired sera collected from children with respiratory tract infections who were positive for HBoV1 according to PCR analysis. Conclusions/Significance: Our data indicate that HBoV1 is more prevalent than HBoV2, HBoV3, and HBoV4 in the population we sampled in Beijing, China, suggesting that HBoV species may play differential roles in disease. \u00a9 2012 Guo et al.",

In this study, we used genomic and immunologic approaches to identify the reactive epitopes conserved across multiple HBoV species and explored their potential as the basis of a novel diagnostic test for HBoVs. Methodology/Principal Findings: We generated HBoV1-3 VP2 gene fragment phage display libraries (GFPDLs) and used these libraries to analyze mouse antisera against VP2 protein of HBoV1, 2, and 3, and human sera positive for HBoVs. Using this approach, we mapped four epitope clusters of HBoVs and identified two immunodominant peptides-P1 ( ",

We investigated antibody responses against influenza A(H7N9) virus in 48 serum samples from 21 patients, including paired samples from 15 patients. IgG against subtype H7 and neutralizing antibodies (NAbs) were not detected in acute-phase samples, but ELISA geometric mean titers increased in convalescent-phase samples; NAb titers were 20-80 (geometric mean titer 40). Avidity to IgG against subtype H7 was significantly lower than that against H1 and H3. IgG against H3 was boosted after infection with influenza A(H7N9) virus, and its level in acute-phase samples correlated with that against H7 in convalescent-phase samples. A correlation was also found between hemagglutinin inhibition and NAb titers and between hemagglutinin inhibition and IgG titers against H7. Because of the relatively weak protective antibody response to influenza A(H7N9), multiple vaccinations might be needed to achieve protective immunity.",

        "abstract": "Tidal marshes are an important habitat and nursery area for fish. In the past few decades, rapid economic development in the coastal areas of China has led to the interruption and destruction of an increasing number of tidal marshes. The growing interest in tidal marsh restoration has increased the need to understand the relationship between geomorphological features and fish assemblages in the design of marsh restoration projects. We studied temporal variations in, and the effects of creek geomorphological features on, the estuarine tidal creek fish community. Using modified channel nets, we sampled fish monthly from March 2007 to February 2008 from seven tidal creeks along an intertidal channel system in Chongming Dongtan National Nature Reserve. Fourteen creek geomorphological variables were measured or derived to characterize intertidal creek geomorphological features. The Gobiidae, with 10 species, was the most speciesrich family. The most abundant fish species were Liza affinis, Chelon haematocheilus, and Lateolabrax maculatus. The fish community was dominated by juvenile marine transients, which comprised about 80% of the total catch. The highest abundance of fish occurred in June and July, and the highest biomass occurred in December. Canonical redundancy analyses demonstrated that depth, steepness, cross-sectional area, and volume significantly affected the fish species assemblage. L. affinis favored small creeks with high elevations. Synechogobius ommaturus, Acanthogobius luridus, and Carassius auratus preferred deep, steep creeks with a large cross-sectional area and volume. These findings indicate that the geomorphological features of tidal creeks should be considered in the conservation and sustainable management of fish species and in the restoration of salt marshes. \u00a9 2014 Chinese Society for Oceanology and Limnology, Science Press and Springer-Verlag Berlin Heidelberg.",

However, the entry properties and tropism of this H7N9 virus were poorly understood. Moreover, neuraminidase inhibitor resistant H7N9 isolates were recently observed in two patients and correlated with poor clinical outcomes. In this study, we aimed to elucidate the entry properties of H7N9 virus, design and evaluate inhibitors for H7N9 virus entry. We optimized and developed an H7N9-pseudotyped particle system (H7N9pp) that could be neutralized by anti-H7 antibodies and closely mimicked the entry process of the H7N9 virus. Avian, human and mouse-derived cultured cells showed high, moderate and low permissiveness to H7N9pp, respectively. Based on influenza virus membrane fusion mechanisms, a potent anti-H7N9 peptide (P155-185-chol) corresponding to the C-terminal ectodomain of the H7N9 hemagglutinin protein was successfully identified. P155-185-chol demonstrated H7N9pp-specific inhibition of infection with IC",

        "abstract": "Two clinical phenotypes for citrin deficiency (CD) have been reported. One is adult-onset citrullinemia type II (CTLN2) and another is neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD). A child with CD and who had failure to thrive (FTT) and dyslipidemia as main clinical manifestations is reported here. Both the weight- and length-for-age at 18 months dropped below the 3rd percentile in the corresponding WHO anthropometry percentile charts, while blood biochemical analysis revealed dramatically increased triglyceride and total cholesterol, together with reduced HDL-cholesterol. Inquiries revealed his aversion to rice and fondness for fish since the age of one year, a peculiar habit which could not be corrected. Since the age of two years, the peculiar diet became more obvious, and slightly increased citrulline and threonine levels were detected on blood amino acid analysis. At the age of two years and five months he was suspected to have CD. Since then, he has been fed in accordance with his own food preferences, and FTT improved gradually, with weight-for-age, in particular, recovering beyond the 3rd percentile at three years of age, and dyslipidemia was also ameliorated gradually. SLC25A13 gene analysis revealed a homozygote of 851de14, and CD was thus confirmed. Diet survey at four years and seven months revealed a fondness for high-protein and low-carbohydrate foods, such as seafood, meat, eggs and milk. This child presented with FTT and dyslipidemia as main clinical manifestations and this was a novel CD phenotype different from NICCD and CTLN2.",

We herein reported the etiology distribution feature in a cohort of 285 Chinese patients with NDDs. Although concrete NDD etiologies in 48.4 of the total patients could not be identified, genetic diseases (with the proportion of 35.8 in the total cases) including inborn errors of metabolism (IEM) and congenital dysmorphic diseases, constituted the commonest etiology category for NDDs in this study. The two key experimental technologies in pediatric metabolomics, gas chromatography-mass spectrometry (GC-MS), and tandem mass spectrometry (MS-MS), proved to be substantially helpful for the exploration of the NDD etiologies in this clinical investigation. The findings in this paper provided latest epidemiologic information on the etiology distribution of NDDs in Chinese, and the syndromic NDDs caused by citrin deficiency and the novel chromosomal karyotype, respectively, further expanded the etiology spectrum of NDDs.

        "abstract": "Citrin is a liver-type aspartate/glutamate carrier (AGC) encoded by the gene SLC25A13. Two phenotypes for human citrin deficiency have been described, namely the adult-onset citrullinemia type II (CTLN2) and the neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD). However, citrin deficiency currently remains a perplexing and poorly recognized disorder. In particular, description of post-NICCD clinical presentations before CTLN2 onset is rather limited. Analysis of SLC25A13 mutations, identification of dysmorphic erythrocytes, hepatobiliary scintigraphic imaging and investigation of post-NICCD clinical presentations were performed in a citrin-deficient cohort comprised of 51 cases of children diagnosed with citrin deficiency in a Chinese pediatric center. Twelve SLC25A13 mutations were detected in this cohort, including the novel V411M and G283X mutations. Among the 51 citrin-deficient subjects, 7 cases had echinocytosis, which was associated with more severe biochemical abnormalities. Delayed hepatic discharge and bile duct/bowel visualization were common scintigraphic findings. Moreover, 9 of the 34 post-NICCD cases demonstrated concurrent failure to thrive and dyslipidemia, constituting a clinical phenotype different from NICCD and CTLN2. The novel mutations, echinocytosis, hepatobiliary scintigraphic features and the novel clinical phenotype in this study expanded the genotypic and phenotypic spectrum of citrin deficiency, and challenge the traditionally-assumed 'apparently healthy' period after the NICCD state for this disease entity.",

Diagnosis was confirmed by PCR amplification and direct sequencing of all the 19 exons and their flanking sequences of COMP gene, and the mutation was further ascertained by cloning analysis of exon 10. The child presented with short and stubby fingers, bow leg, short limb dwarfism and metaphysic broadening in long bone as well as lumbar lordosis. A mutation c.1048-1116del (p.Asn350-Asp372del) in exon 10, inherited from his father who did not demonstrate any phenotypic feature of PSACH, was detected in the child. PSACH was diagnosed definitively by means of COMP mutation analysis, on the basis of the child's clinical and imaging features. The non-penetrance phenomenon of COMP mutation was described for the first time in PSACH.",

        "title": "Mutation spectrum of the CFTR gene in Taiwanese patients with congenital bilateral absence of the vas deferens",
        "abstract": "Background: Clinically affected cystic fibrosis (CF) patients present a spectrum of genital phenotypes ranging from normal fertility to moderately impaired spermatogenesis and congenital bilateral absence of vas deferens (CBAVD). Little is known about the CF incidence in the Taiwanese population. It has been shown that the CBAVD in men without clinical evidence of CF is associated with a high incidence of mutated CFTR (cystic fibrosis transmembrane conductance regulator) alleles. In order to understand the involvement of the CFTR gene in the aetiology of Asian/Taiwanese male infertility, we screened the entirety of the CFTR gene in 36 infertile males with CBAVD. Methods: Temporal temperature gradient gel electrophoresis (TTGE) followed by direct DNA sequencing was used. Results: Five mutations, p.V201M, p.N287K, c.-8G>C (125G>C), p.M469I and p.S895N, were found in five of the patients. p.N287K occurred in the first transmembrane-spanning domain, p.M469I in the first ATP-binding domain and p.S895N in the second transmembrane-spanning domain, were novel. In addition, seven homozygous and seven heterozygous 5T alleles in the intron 8 poly(T) tract were found. The overall frequency of CFTR mutant alleles in Taiwanese CBAVD males was 26 out of 72=36%. This finding was lower than the published frequency of CFTR mutations in other ethnic CBAVD patients (ranging from 50 to 74%). The frequency of p.M470V in Taiwanese CBAVD patients is not significantly different from that in the general population P=0.12). Conclusions: The results of this study add to the short list of Taiwanese/Asian CFTR mutations. Unlike Caucasian patients, the CFTR mutations cannot account for the majority of Taiwanese CBAVD. This is consistent with the low incidence of CF in the Asian/Taiwanese population. Furthermore, the mutation spectrum of CFTR in CBAVD patients does not overlap with the Caucasian CFTR mutation spectrum. \u00a9 The Author 2005.

The Corex process was optimized and the energy consumption was minimized according to the relationship of gas production in the smelting unit and the degree of iron ore reduction in the reduction unit. It was proven that the most important factor for saving energy in smelting reduction process is to use coal with suitable effective calorific value for the smelting heat of iron ore.",

Methods: SD rats divided into 7 groups, were given Radix Aconiti Lateralis Preparata (1.14 g materia medica/kg, 3.43 g materia medica/kg, 10.30 g materia medica/kg), Radix Aconiti (13.0 g materia medica/kg), Radix Aconiti kusnezoffii (8.3 g materia medica/kg), negative control (distilled water), and positive control (vitamin A). Administration to the rats of treatment groups and negative control group lasted 10 days from the 7th to 16th day after pregnancy, but administration in the positive control group were given for 4 days, lasting from the 9th to 12th day after pregnancy. Results: Malformation of external, internal organ and bone weren't found in fetuses treated with three doses of Radix Aconiti Lateralis Preparata. But the body weight growth and food consumption were reduced in the pregnant rats at the high dose of three drugs, and the body length and the breastbone calcification of fetuses decreased at 8.3 g/kg dose of Radix Aconiti kusnezoffii. Conclusion: The results indicated that Aconitum (Radix Aconiti Lateralis Preparata, Radix Aconiti, Radix Aconiti kusnezoffii) didn't induce teratogenecity to the rats, but Radix Aconiti kusnezoffii shows embryotoxicity to the fetus.",

Other untreated seeds were regarded as a control group (abbreviated to CP). All seeds were planted under same condition. The vegetal character of the Catharanthus roseus was observed in detail and contents of Vinblastine and Vincristine in the plants were detected by HPLC. Experimental results indicated that the contents of Vinblastine increased remarkably and Vincristine tended to increase in the plants of the pressure treated groups in comparison to CP. It is also noticed that distributions of variance of the flowers and ill after growth plants are corresponding approximately to that of the contents of Vinblastine. Mechanism of the effects of pressure treatment was discussed qualitatively.",

In this study, oral administration of CXVO (45.0, 90.0, and 135.0 \u03bcl/kg) to mice significantly elevated the pain threshold in the hot-plate test and reduced the number of abdominal writhing caused by acetic acid. CXVO (90.0 and 135.0 \u03bcl/kg) not only reduced locomotor activity, but also prolonged the sleeping time induced by sodium pentobarbital (35 mg/kg), and the number of mice with sleeping time over 1 min by sodium pentobarbital (25 mg/kg) was markedly enlarged by CXVO (45.0, 90.0, 135.0 \u03bcl/kg) administration. The three doses of CXVO significantly increased the pain threshold of rabbits with headache due to hot radiation and the level of plasma ET of rats with headache due to nitroglycerin injection. Besides, for the nitroglycerin-induced headache rats, the c-fos gene expression in the brain stem and hypothalamus was remarkably inhibited and the level of plasma CGRP was reduced significantly after CXVO administration at both doses 90.0 and 135.0 \u03bcg/kg. The latter dosage could also raise the level of plasma 5-HT markedly. The study suggests that CXVO acts probably as the active ingredient of Rhizoma Ligustici Chuanxiong Hort.

The components of the essential oils obtained by hydrodistillation were investigated by GC-MS. The antibacterial activity of the essential oils was determined by micro-dilution assay. The results showed large variations in the chemical composition and antibacterial activity of the oils. The oil of \"Yimucao\" showed antibacterial activity against various Gram-positive bacteria and consisted mainly of sesquiterpenes and diterpenes, with phytone, phytol, caryophyllene oxide and \u03b2-caryophyllene being the most significant constituents, whereas the oil of \" Chongweizi\", mainly made up of bornyl acetate and aliphatic hydrocarbons, was inactive in the antibacterial assay. Further study of the main compounds in \"Yimucao oil\" showed that \u03b2-caryophyllene had wide-spectrum activity against Gram-positive bacteria. \u00a9 2013 by the authors.",

        "abstract": "Objective: Exploring the effect and safety of local intra-arterial thrombolysis (LIT) on acute central retinal artery occlusion (CRAO). Methods: Retrospective data analysis of 49 consecutive CRAO patients was performed. The visual acuity was 3.0-4.7 in 51% patients, and less than 3.0 in 49%. The averaged visual acuity was 1.5 \u00b1 0.1. All the patients were treated with urokinase perfusion through the ophthalmology artery within the first 6 hours after CRAO attack. Conventional treatment including intra-ocular pressure decreasing, microcirculation improvement, neuroprotection and anti-coagulation were conducted. The visual acuity was detected at the 2, 28 days and 6 months after thrombolysis, and field of visions was detected at 28 days and 6 months after thrombolysis. And the thrombolysis related complications were observed. The correlation of the visual outcome after thrombolysis with the patient's ages, the time thrombolysis when started, and the residual visual acuity at admission were calculated. The complication which was related to cerebral angiography and LIT was explored. Results: Improvement of visual function was achieved after thrombolysis. The averaged visual acuity was 4.2 \u00b1 0.2, 4.4 \u00b1 0.3, 4.6 \u00b1 0.5 at the 2,28 days and 6 months after thrombolysis respectively. 24.5% patients regained visual acuity of > 4.8, and visual field deficit was less than 30% in 34.7% at 28 days. 6 months later, 36.7% patients regained visual acuity of > 4.8. Field deficit was less than 30% in 44.9% patients. The pretreatment residual visual acuity was the significant predictor of good recovery of visual acuity (r=0.292, P < 0.05). There was no ischemic attack and hemorrhagic complication which correlated with cerebral angiography and LIT. Conclusion: LIT is an effective and safe method for CRAO patients. The pretreatment residual visual acuity is the significant predictor of good outcome.",

        "abstract": "Objective: The aim of this study was to evaluate the feasibility and therapeutic effectiveness of ultrasonography (US)-guided percutaneous microwave ablation (PMA) in the treatment of peripheral lung cancer. Methods: From December 2002 to September 2003, 12 Chinese patients with 16 histologically proven lung malignant tumors (6 primary and 10 metastatic) were treated with US-guided PMA. All tumors were located at the peripheral portions of the lung where the tumors were in direct contact with visceral pleura and visualized on US. A total of 21 insertions with 25 applications was administered to the 16 tumors. There was no radiation or chemotherapy combined with PMA. Results: Based on the follow-up period of 6-40 months (average=20 months), seven patients survived without serious complications and five patients died from metastasis after PMA. The size of treated tumors was decreased in all cases (10 tumors with moderate to remarkable area reduction and 6 tumors with mild area reduction). Blood flow in the tumors became either invisible or diminished on color Doppler flow imaging, which showed 9 tumors with no enhancement and 7 tumors with partially decreased enhancement on contrast-enhanced computed tomography after PMA. All patients experienced improvement of clinical symptoms after PMA treatment. Conclusions: Ultrasonography-guided PMA, a mildly invasive procedure, is an effective, safe, and feasible method for treating peripheral lung tumors. Percutaneous microwave ablation provides an alternative therapy for patients with inoperable peripheral lung cancer as well as for patients who refuse radiation or chemotherapy. \u00a9 2006 Elsevier Inc.

Design: Prospective, noncomparative, interventional case series. Participants: 19 (22 eyes) healthy age-related cataract patients. Methods: The study was performed in patients who had been operated with phacoemulsification by the same ophthalmologist. Endothelial density and morphological changes in central cornea were examined with CMTF just before operation and on the day of 1 week, 1 month, 3 months and 6 months after operation. Main Outcome Measures: Endothelial density and endothelial morphological images with CMTF. Results: CMTF images reveal that the shape of endothelium is quite different after phacoemulsification. Keratic precipitation, endothelial edema, endothelial absent area and pseudoguttata-like changes can be seen. Also, the resealing process of endothelium adjacent endothelial absent area can be observed. Before operation, the average endothelial density is 2491\u00b1602, while at the time points of 1 week, 1 month, 3 months and 6 months after operation it was 2112\u00b1640, 2058\u00b1673, 2129\u00b1711, 2084\u00b1635, respectively, which are significantly lower than that before operation (P<0.05). Conclusion: Human corneal endothelial loss can't regenerate by mitosis; Endothelium injury after phacoemulsification can present as endothelial edema, endothelial absent area and pseudoguttata-like changes. The area of endothelial absence can be resealed by the neighbor endothelia.",

Painful ophthalmoplegia is a rare disorder characterized by orbital or retro-orbital pain with accompanying paresis or paralysis of one or more of the extraocular motor nerves with or without involvement of the ipsilateral trigeminal nerve. In clinical, other lesions involving the structures within these areas may also cause a painful ophthalmoplegia syndrome, such as ophthalmoplegic migraine, aneurysms of cavernous carotid artery, vasculopathic cranial neuropathy secondary to diabetes mellitus, nasopharyngeal carcinoma.

        "abstract": "Objective: To determine clinical outcomes of vitrectomy and silicone oil tamponade combined with phacoemulsification and foldable intraocular lens (IOL) implantation for the treatment of severe proliferative diabetic retinopathy (PDR). Methods: Fifty-three patients (57 eyes) with proliferative diabetic retinopathy were included in this study. All patients had tractional or tractional-rhegmatogenous retinal detachment. These patients were divided into combined surgery group and vitrectomy group. Thirty-three patients (33 eyes) of combined surgery group underwent vitreoretinal surgery and silicone oil tamponade combined with phacoemulsification and foldable intraocular implantation. Twenty patients (24 eyes) of vitrectomy group underwent vitreoretinal surgery and silicone oil tamponade only. The postoperative rates of retinal reattachment and complications were analyzed. Results: Rates of retinal reattachment in combined surgery group was 87.9% vs. 83.3% for vitrectomy groups. The difference in rates of retinal reattachment was not statistically significant between these 2 groups (P > 0.05). Rates of visual acuity better than 0.1 in combined surgery group was 60.6% vs. 33.3% in vitrectomy group 6 month after operation. The difference in rates of postoperative iris neovascularization was not statistically significant between these 2 groups (P > 0.05). Conclusions: Combined vitreoretinal surgery and phacoemulsification with intraocular lens implantation is safe and effective in treating severe proliferative diabetic retinopathy. Combined surgery may prevent a second operation for postvitrectomy cataract, allowing earlier visual rehabilitation.",

Compared with the coutrol rat, it was indicated that the opening angles and residual strains expressed by cutting at the muscular portion were basically identical along longitudinal location and those expressed by cutting at the cartilaginous region increased in the longitudinal direction in the asthma rat. The results shows that the muscle of trachea gradually growed because of changes of the mechanical environment, resulting in remodeling of the asthma rat trachea.",

Methods: Serum proteomics of 18 dampness syndrome cases, 17 non-dampness syndrome cases in chronic gastritis patients and 8 normal controls were analyzed by surface enhanced laser desorption/ionization-time of flight (SELDI-TOF) protein-chip. Results: There was a high expression trend in three ratios of charge (of an electron) to mass (M/S) of 3.2 kD, 6.4 kD and 8.1 kD of protein expression spectrum from patients with chronic gastritis dampness syndrome, and the wave peak value was over 10 units. There was a low expression trend in above-mentioned sites of protein expression spectrum from patients with chronic gastritis non-dampness syndrome and normal group. The wave peak value of patients with chronic gastritis non-dampness syndrome was about or below 10 units, and the wave peak value in normal group was below 5 units. Conclusion: There exists a certain significance to explore biologic theory basis of chronic gastritis dampness syndrome by analyzing the serum proteomic.",

The full-length cDNA of Sphy1 was 1644 bp predicated to encode 547 amino acids including an N terminal signal peptide of 27 amino acids. Phylogenetic analysis indicated that Sphy1 had high similarities with the phytase genes from Medicago truncatula and rice, and acid phosphatase genes from M. truncatula and Arabidopsis. Prokaryotic expression of Sphy1 in Escherichia coli BL21 (DE3) showed that the induced protein had high phytase activities. The transcripts of Sphy1 could be detected in various tissues, such as cotyledons, leaves, stems and roots of seedlings. The phytase activities in the above tissues were in accordance with their corresponding Sphy1 transcripts. The transcripts of Sphy1 in cotyledons showed an increasing trend from 5 to 30 days after germination, suggesting that Sphy1 had involved the hydrolyses of the organic phosphorus compounds in seeds from the stages of early seed germination to young seedlings in soybean. Therefore, it was speculated that Sphy1 played an important role during the seed germination and the growth of the seedlings by releasing inorganic phosphorus (P\n                        ",

In this paper, nineteen rice CBF genes, including seven previously released and twelve unpublished novels, were identified and characterized. The multi-members of rice CBFs (OsCBF1 to OsCBF12) were divergent at the nucleotide and amino acid level. Expression analysis shows that five novel rice CBF genes (OsCBF1, OsCBF2, OsCBF3, OsCBF8, and OsCBF9) responded to short-term (1 h or 3 h) stresses of low temperature, salt stress and dehydration. The transcripts of OsCBF2, OsCBF8 and OsCBF9 in the roots were rapidly elevated when the plants were exposed to low temperatures, suggesting that they were possibly involved in low temperature responses in rice plants. Meanwhile, the expression level of OsCBF2 in leaves was enhanced when exposed to salt stress of 1-3 h, implying that OsCBF2 functioned as a transduction component in the salt stress signal cascade. Various expression patterns in OsCBF1, OsCBF2, OsCBF3, OsCBF8, and OsCBF9 under low temperature, salt and drought conditions, together with the different expression patterns between roots and leaves for each of these indicated that every rice CBF gene has unique and non-redundant functions in the response to the abiotic stresses. \u00a9 2008 Higher Education Press and Springer-Verlag GmbH.",

        "abstract": "Due to the huge amount in the soil, phytate is an important potential source for providing the plants with available phosphorus (Pi) by the involved catalytic reaction of phytase. In this study, a construct fusing the open reading frame (ORF) of Sphy1 into corresponding positions in the fragment of binary expression vector pBI121 was created and used to transform tobacco. Molecular identification by PCR and RT-PCR indicated the target gene Sphy1 in the transgenic tobacco plants was transcribed under the regulation of an upstream promoter. Compared with the control plants, the phytase activities in all the transgenic plants were increased, with the increased range consistent with the expression levels in the transgenic plants. Under the growth conditions with phytate as the sole phosphorus source, the transgenic line 1 plants displayed a high expression level of Sphy1 and shows notable improved growth performance, such as higher fresh weight and dry weight, as well as higher total P content and more accumulative P amount per plant than CK. This clearly indicated that overexpression of Sphy1 could improve the phosphorus acquisition by the extruded Sphy1 phytase in the rhizosphere, where this enzyme could catalyze the degradation of the phytate and release the available Pi for plants. The Sphy1 gene seemed to have a potential value in the creation of new crop cultivars with high phosphorus use efficiency. \u00a9 Higher Education Press and Springer-Verlag 2009.",

        "abstract": "Acquisition of inorganic phosphate (Pi) by plant roots is performed by phosphate transporters (PTs) located at the cytoplasmic membranes of epidermal cells and root hairs. A Triticum aestivum PT gene denoted as TaPT2 was functionally characterized in this study. TaPT2 is highly similar to TtPT2 and HvPT2, two PHT1 family genes in T. aestivum/Thinopyrum intermedium and barley, respectively. TaPT2 is 1,802 bp long at the cDNA level; it encodes a 525-amino acid polypeptide with a molecular weight of 57.5 kDa and an isoelectric point of 8.65. TaPT2 contains 12 conserved membrane-spanning domains and is transported to the cytosolic membrane after endoplasmic reticulum sorting. Functional complement analysis revealed that TaPT2 endowed Pi transporter activities in a yeast mutant that is defective in Pi uptake, with high-affinity Pi acquisition. TaPT2 transcripts were specifically detected in the roots. The transcripts were upregulated under Pi deprivation and downregulated under Pi sufficiency. These results suggest that TaPT2 expression is associated with external Pi concentration. Transgene analysis revealed that TaPT2 overexpression or knockdown did not regulate plant dry mass production, Pi acquisition, and photosynthetic capacity under Pi sufficiency. Under Pi deprivation, TaPT2 overexpression increased plant dry mass accumulation, total P content per plant, and photosynthetic efficiencies, whereas TaPT2 downregulation reduced plant dry mass, accumulative P amount, and photosynthetic parameters. These results collectively suggest that TaPT2 is a high-affinity PHT1 member that has important functions in mediating plant Pi uptake under Pi deprivation. TaPT2 can serve as a useful gene resource for the improvement of phosphorus use efficiency in cereals under Pi deprivation. \u00a9 2014 Franciszek G\u00f3rski Institute of Plant Physiology, Polish Academy of Sciences, Krak\u00f3w.",

        "abstract": "MicroRNAs (miRNAs) are highly conserved non-coding small RNAs involved in regulating plant growth and development, as well as plant responses, to diverse environmental signaling cues. In this study, the expression patterns of 38 wheat microRNAs (TaMIRs) were investigated under normal N and low N stress. Under normal N conditions, the TaMIRs exhibited four expression patterns: high, moderate, low, and undetectable expression. Seven TaMIRs (TaMIR156, TaMIR399, TaMIR444, TaMIR1118, TaMIR1129, TaMIR1133, and TaMIR1136) showed varied expression levels under N deprivation. TaMIR156, TaMIR444, TaMIR1118, TaMIR1129, and TaMIR1136 were upregulated, whereas TaMIR399 and TaMIR1133 were downregulated. The expression patterns of TaMIR444, TaMIR1118, and TaMIR1129 were further analyzed under various low N concentrations and then returned to normal N. The aforementioned TaMIRs exhibited ever higher expression at lower N concentrations and whose expressions returned to those before low N stress after they were restored to normal N conditions, which suggest that N concentration and low N-duration are inversely correlated with their expression. The putative target genes of the low N\u2013responsive TaMIRs were identified and categorized into various functional groups. Expression analysis revealed that the target genes showed opposite pattern to that of their corresponding TaMIRs. Our results suggested that some low N\u2013responsive TaMIRs are involved in regulating plant response to N deprivation by interacting with their target genes. Distinct TaMIRs are potentially involved in plant tolerance to low N stress through microRNA-mediated pathways.",

Among them, 16 cases were undergone enhanced MRI, 21 undergone diffusion weighted imaging; 19 cases studied with CT, and 4 were with enhanced CT. Results: Multiple perivascular spaces were found in cerebral and cerebellar hemispheres bilaterally, shaped round or oval, punctual, strip or linear with clear borderline in all 130 cases. The lesions shaped strip or linear usually clustered and arrayed along the white matter fasciculi. Their location was consistently in around anterior commissure (97. 69%, 127/130), centrum semiovale near high-convexity of the cerebrum (85. 38%, 111/130), cerebral peduncles (37. 69%, 49/130), extreme capsules (23. 85%, 31/130), and only one case's lesion was in cerebellar whiter matter. The signal of perivescular spaces was isointense relative to CSF on all MR pulse sequences, and with no enhancement after injection of contrast agent. No change was noted on follow-up MRI. Mild spaces were identified in all cases of all ages, and large spaces were found in 17 cases, 3 of them had mild mass effect. Conclusion: Perivascular spaces can be identified in all persons of all ages, and usually locate in such as around anterior commissure, centrum semiovale near high-convexity of the cerebrum, cerebral peduncles, extreme capsules. They are round or oval, punctual, strip or linear, and have no mass effect, usually are isointense relative to CSF on all MR pulse sequences.",

However, the mechanisms underlying polarized regulation of this pathway remain unclear. In this study, we report that the instability of Akt regulated by the ubiquitin-proteasome system (UPS) is required for neuron polarity. Preferential distribution in the axons was observed for Akt but not for its target GSK-3\u03b2. A photoactivatable GFP fused to Akt revealed the preferential instability of Akt in dendrites. Akt but not p110 or GSK-3\u03b2 was ubiquitinated. Suppressing the UPS led to the symmetric distribution of Akt and the formation of multiple axons. These results indicate that local protein degradation mediated by the UPS is important in determining neuronal polarity. \u00a9 The Rockefeller University Press.",

Methods: Wistar rats were randomized into five groups: group A in which no treatment was given, group B in which ANIT was given on the eighth day, group C in which high dosage of hydroxyanthroquinones from Rheum Palmatum L was given, group D in which low dosage of hydroxyanthroquinones from Rheum Palmatum L was given, group E in which \"Yinzhihuang injection\" was given as positive control. Except group A and B, other groups were given corresponding drugs for 7 days and then additionally administered ANIT to induce jaundice on the eighth day. Forty-eight hours later, the rats' blood was gained from eyes and the serum was separated. The liver functional sign, the activity of SOD, the content of MDA in serum and change in pathology of liver tissue were observed. Results: Compared to group B, ALT, AST, TBIL, ALP, \u03b3-GT, MDA of group C and E descended obviously (P < 0.01), and SOD went up obviously (P < 0.01). By examining the liver pathology, we found that hepatic cellular change, necrosis and hepatominicholange hyperplasia could be notably alleviated in group C. Except that TBIL rose obviously (P < 0.01), the other signs of group C were not different from those of group E (P > 0.05). Conclusion: Hydroxyanthroquinones from Rheum Palmatum L has the action of reducing serum bilirubin and transaminase and improving liver tissue injury in rats of experimental Cholestasis.",

        "abstract": "Objective: Neurogenic inflammation has been confirmed to exist in migraine by pathological research; therefore, it is necessary to deepen the understanding of related content on neurogenic inflammation in migraine, which is meaningful to guide the clinical research. Data Sources: A computer-based online search of PUBMED database was undertaken to identify related articles published in English between January 1995 and December 2005 with the key words of \"migraine, neurogenic inflammation\". Study Selection: The data were examined firstly, and the quotations of every article were looked over. Inclusive criteria: Articles correlated with the neurogenic inflammation involved in migraine. Exclusive criteria: Repeated search or Meta analytic articles. Data Extraction: Among the 97 collected articles, 29 ones were consistent with the inclusive criteria and 69 ones were out of date or repetitive. In the 29 inclusive articles, 17 ones involved in neuropeptide, 6 involved in inflammatory related factors, 1-related to cortical spreading depression, 2 involved in serotonin, 2 involved in endothelin and 1 involved in gamma-aminobutyric acid. Data Synthesis: The trigeminovascular theory is dominant in the pathogenesis of migraine, and neurogenic inflammation is the key element of it. Previous research has confirmed that neurogenic inflammation exist in migraine. Release of neuropeptide, mainly calcitonin gene-related peptide, substance P and neurokinin A and the following neurogenic inflammation are proposed to be the pathophysiogical foundation. Release of inflammatory factors such as \u03b2-transforming growth factor, interleukin-8, histamine and so on and increased activated platelet also participate in this course. Animal experiments have shown that cortical spreading depression and endothelin play important roles in rat dural neurogenic inflarnmation; 5-hydroxytryptamine",

        "abstract": "Context: The alteration of protein expression in white adipose tissue (WAT) may contribute to the pathogenesis of obesity. Objective: The aim of the present study was to uncover proteins differentially expressed in the WAT of overweight/obese subjects and study the role of the identified proteins in adipocyte differentiation. Design and Setting: Two-dimensional electrophoresis and matrix-assisted laser desorption ionization-time of flight-mass spectrometry were used to identify proteins differentially expressed in WAT between obese/overweight and control groups. Cathepsin K (CTSK), one of the proteins identified by the above methods, was highlighted to assess its effects on adipocyte differentiation through 3T3-L1 cell line. Results: Human visceral adipose tissue of overweight/obese subjects displayed a differential protein expression profile, compared with that of normal-weight controls. CTSK was up-regulated in the WAT of overweight/obese subjects, and it had a significant positive correlation with body mass index. In vitro study showed that CTSK expression and its enzyme activity gradually increased in the process of adipocyte differentiation. Moreover, E-64, an inhibitor of CTSK, could prevent adipocyte differentiation in a dose-dependent manner, which was characterized by the absence of triglyceride accumulation and glycerol contents. Conclusions: CTSK, a cysteine protease involved in extracellular matrix remodeling, could be one of the determinants of adipocyte differentiation. CTSK may be involved in the pathogenesis of obesity by promoting adipocyte differentiation. Copyright \u00a9 2006 by The Endocrine Society.",

The approximator, which was realized by radial basis function networks, was used for learning the nonlinear fault functions to monitor the abnormal behavior of dynamic system. When faults occured, the on-line approximator could not only detect all possible unknown faults, but also estimate the faults vector. By the definition of dead area function, it was proved that the scheme had good robustness against modeling error and uncertainties.

Data Sources: An online search of Medline was undertaken to identify articles about the rhabdomyolysis published in English between January 1989 and April 2006 by using the key words of \"rhabdomyolysis\". Meanwhile, Chinese literatures about the rhabdomyolysis published between January 2000 and April 2006 were collected from the CNKI database with the key words of \"rhabdomyolysis\" in Chinese. Study Selection: The literatures were checked firstly, and those related to rhabdomyolysis were selected and then looked for the full-texts. Inclusive criteria: Experimental researches on rhabdomyolysis. Exclusive criteria: Repeated studies and Meta analytical papers. Data Extraction: A total of 199 literatures about rhabdomyolysis were collected, including 48 reviews, 17 experimental researches and 134 clinical case reports. DATA SYNTHESIS: 17 experimental researches included about 74 patients and 340 experimental animals, and it was proved that unscientific movement training might cause the waste of organism energy, increase of free radicals, reinforced permeability of tissues, and thus causing the releasing of inflammatory factors and induce the injury in muscles. Acute renal failure and multi-organ functional disorder were even found in some patients. It is the most important now to perform the treatment according to the cause of disease, decrease muscular injuries, recover the blood flow, and prevent and cure acute renal failure. Conclusion: Rhabdomyolysis is a skeletal muscle injury caused by over-exercise, which represent in clinic as myosalgia, engorgement, powerless, and brown urine. Its main symptoms are increased serum creatin kinase and myoglobulin with myoglobulinuria accompanied by acute renal failure. Early recognition and treatment in the acute phase of rhabdomyolysis is key to the prognosis and clinical treatment of acute renal failure.",

Methods: Retrospectively analyzed the data of 246 patients with primary massive liver carcinoma who were treated by intra-hepatic artery chemotherapy and embolizing therapy. These patients were randomly divided into two groups: one group (treatment group, 126 cases) was embolized by iodinated oil (6-27 ml), ferrosoferric oxide (250 \u03bcm), mitomycin (10 mg) and 5 Fluorouracil (250 mg), and the stem of hepatic artery were embolized with gelatin sponge. The other one (control group, 120 cases) was treated by iodinated oil (6-27 ml) and gelatin sponge only. Then compared the size of the tumor, the effective rate and the survival rate in near future between these two groups. Results: The effective rate in near future of the treatment group is higher than that of the control group. The survival rate in 1, 2 and 3 years was 89.3%, 42.7%, and 31.2% respectively in treatment group, and in the control group, the number was 53.8%, 14.9%, and 12.6% respectively. Conclusion: Compared with single embolizing therapy, combining the intra-hepatic artery chemotherapy with embolizing therapy can increase the effective rate and survival rate in near future significantly. This method is effective in treating the metaphase and advanced primary massive liver carcinoma.",

Methods: Preoperative MRA was performed in 59 patients with portal hypertension (study group) in order to search for the causes of portal hypertension, to observe the patterns and route of the hepatic and portal veins and to measure the vascular diameter at the scheduled puncture site. MRA was also performed in 50 healthy subjects, which was served as the control group. The results were compared between two groups. Results: The diseases in the study group included simple cirrhosis (n = 49), cirrhosis accompanied with hepatocellular carcinoma (n = 4), pure portal vein thrombosis (n = 3), splenic vein stenosis (n = 1) and Budd-Chiari syndrome (n = 2). In study group the type I, II and III of the hepatic vein classification were seen in 14, 39 and 12 cases respectively, while in control group in 12, 34 and 14 cases respectively. In study group, the right, middle and left hepatic vein which had the diameter larger enough for puncturing existed in 52, 40 and 28 cases respectively, while in control group in 46, 34 and 23 cases respectively. The safe point for puncture via the right and the left branch of the portal vein was located beyond the distance of (16.2 \u00b1 3.1) mm and (14.2 \u00b1 3.8) mm respectively. Conclusion: MRA is a valuable non-invasive examination, which is of great value in determining the causes of portal hypertension and in planning the puncturing sites before performing TIPS.",

Methods: PASMAM-1054 and CDMAM 3.4 phantom of different thickness were exposed on DR, PCM and CR systems under automatic exposure control (AEC) mode, respectively. The average glandular dose (AGD) and image quality figure (IQF) were calculated to evaluate the difference of imaging quality. The impact of dose on image quality and the effect of different PMMA thickness on the dose were taken into account to compare the overall image quality of three digital mammography systems. Results: The result from PASMAM-1054 phantom indicated that no significant difference were found in imaging quality between DR and PCM (P=0.3960), both DR and PCM system were better than CR system (P=0.0024). The result from CDMAM 3.4 phantom showed that DR system was better than PCM (P<0.05) and CR (P=0.0003) in imaging quality, PCM was better than CR (P=0.0003). Conclusion: Among the three sets of imaging system, the imaging performance of DR and PCM systems was better relatively because of their better imaging quality and lower AGD. The AGD of the CR system was low relatively, however its image quality was worse than the other two systems. The comprehensive imaging capability of CR was not as good as DR and PCM system.",

        "title": "Interventional therapy of refractory hemoptysis complicated with bronchial artery to pulmonary circulation shunt",
        "abstract": "Objective: The presence of bronchial artery to pulmonary circulation shunt (BPS) is the pathologic reason for refractory hemoptysis. Those who have accepted traditional bronchial arterial embolization (BAE) treatment usually carry high risks of recurrence of hemoptysis. At the same time, because of the limits of BAE treatment, safety can not be ignored when we pay full attention to its therapeutic effect. This research aims to find out an effective method to treat the refractory hemoptysis with BPS. Methods: During the period from Sep. 1996 to Feb. 2010, two hundred and twelve patients of hemoptysis were treated with BAE. Of the total 212 patients, BPS was confirmed by DSA angiography in 99, including 72 males and 27 females with a mean age of 47.6 years. The primary diseases included bronchiectasis (n = 25), tuberculosis (n = 64) and inflammatory disorders (n = 10). All patients were treated with BAE. According to the embolization agent used in the treatment the patients were divided into pure Gelfoam group (n = 52) and permanent embolization group (n = 47, using PVA particles, coils, etc.). All patients were followed up regularly at one day, two weeks, four weeks, six months, one year, two years after the treatment. The data were analyzed by using chi square test and rank sum test. Results: Of 52 cases in permanent embolization group, complete cure was achieved in 49, excellent results in 2 and effective response in one. For patients in pure Gelfoam group, complete cure was obtained in 37, excellent results in 16, effective response in 2 and ineffectiveness in 2. Statistic analysis showed that a significant difference in therapeutic effectiveness existed between two groups (P < 0.05). Conclusion: This study clearly indicates that selective bronchial arterial permanent dual embolization is an effective technique for the treatment of refractory hemoptysis, which is definitely superior to the pure Gelfoam emboliztion in obtaining excellent therapeutic results. Besides, for patients with bronchial artery to pulmonary artery shunt bronchial arterial embolization with fine particles is more effective and has fewer complications.",

        "abstract": "Objective: To Compare different methods of quantitative breast density measurement. Methods: The study included sixty patients who underwent both mammography and breast MRI. The breast density was computed automatically on digital mammograms with R2 workstation. Two experienced radiologists read the mammograms and assessed the breast density with Wolfe and ACR classification respectively. Fuzzy C-means clustering algorithm (FCM) was used to assess breast density on MRI. Each assessment method was repeated after 2 weeks. Spearman and Pearson correlations of inter- and intrareader and intermodality were computed for density estimates. Results: Inter- and intrareader correlation of Wolfe classification were 0.74 and 0.65, and they were 0.74 and 0.82 for ACR classification respectively. Correlation between Wolfe and ACR classification was 0.77. High interreader correlation of 0.98 and intrareader correlation of 0.96 was observed with MR FCM measurement. And the correlation between digital mammograms and MRI was high in the assessment of breast density (r = 0.81, P < 0.01). Conclusion: High correlation of breast density estimates on digital mammograms and MRI FCM suggested the former could be used as a simple and accurate method. \u00a9 2011 by the Chinese Medical Association.",

D(\u03b1,\u03b2) is the diagnostic parameter derived from the logistic model. Significant differences were found in D(\u03b1,\u03b2) between the malignant benign groups. Fisher's Linear Discriminant analysis correctly classified more than 90% of the benign and malignant kinetic breast data using the derived diagnostic parameter (D(\u03b1,\u03b2)). Receiver operating characteristic curve analysis of the derived diagnostic parameter (D(\u03b1,\u03b2)) indicated high sensitivity and specificity to differentiate malignancy from benignancy. The dual S-shaped logistic model was effectively used to fit the kinetic curves of breast lesions in DCE-MR. Separation between benign and malignant breast lesions was achieved with sufficient accuracy by using the derived diagnostic parameter D(\u03b1,\u03b2) as the lesion's feature. The proposed method therefore has the potential for computer-aided diagnosis in breast tumors. \u00a9 2011 Science China Press and Springer-Verlag Berlin Heidelberg.",

Methods: The gene expressions were detected by RT-PCR from 56 breast cancer patients before and after TE regimen neoadjuvant chemotherapy (docetaxel and epirubicin). The relationships between these gene expressions and chemotherapy responses were analyzed. Results: The overall response rate to neoadjuvant chemotherapy was 71. 4%, including 8. 9% (5/56) with complete response and 62. 5% (35/56) with partial response. Pathological complete response was found in 4 cases (7. 1%). Stable disease and progression of disease were 23. 2% (13/56) and 5. 4% (3/56), respectively. The expression of Survivin mRNA after neoadjuvant chemotherapy was 35. 7% (20/56), significantly lower than 60. 7% (34/56) before neoadjuvant chemotherapy (P = 0. 008). The expression of BCRP mRNA after neoadjuvant chemotherapy was 19. 6%, significantly lower than 37. 5% before neoadjuvant chemotherapy (P = 0.036). The positive rate of HER-2 mRNA expression was 41. 1% before the chemotherapy, and reduced to 21. 4% after the chemotherapy (P = 0. 025). The effective rates of the single positive expression of Survivin mRNA or BCRP mRNA were both lower than that of negative expression (P < 0.05). The level of HER-2 mRNA expression alone was not significantly associated with the effective rate of chemotherapy (P = 0. 144). When the expression of all Survivin mRNA, BCRP mRNA and HER-2 mRNA were negative, the effective rate of neoadjuvant chemotherapy was higher than that in patients with positive expression (P = 0. 003). The level of Survivin mRNA expression was not significantly associated with BCRP mRNA and HER-2 mRNA (P > 0. 05). Conclusion: The expression of Survivin in combination with BCRP and HER-2 is associated with clinical response to TE neoadjuvant chemotherapy in breast cancer, and can be used as predictive biomarkers for chemosensitivity of TE regimen neoadjuvant chemotherapy for breast cancer.",

METHODS: A total of 110 blood samples from Xinjiang Uygur populations and 45 HL Uygur patients were collected. The sequences encompassing exons 1, 2 and 3 for HLA-A gene were analyzed by direct sequencing of polymerase chain reaction products. The allele frequency distribution of HLA-A in this HL patients was compared with that in control populations. RESULTS: HLA-A high resolution genotypes of 155 samples were assigned successfully by PCR-SBT method. A total of 33 different HLA-A alleles were detected in HL patients and 44 different HLA-A alleles were found in control group.The most frequent antigens were A2 in two groups. It was accorded with Hardy-Weinbery genetic equilibrium law(P=0.61). The frequencies of HLA-A*01: 01: 01: 01, A*03: 01, A*01: 01, A*02: 07 allele were significantly higher than those in control groups(45.48% vs 16.04%, 39.68% vs 18.35%, 33.91% vs 18.35%, 28.18% vs 13.73%, P<0.01), while the frequencies of HLA-A*02: 01, A*11: 01 alleles were significantly lower(69.05% vs 85.47%, 16.81% vs 32.34%, P<0.01). There were no significantly different about antigen types between HL patients and normal people (P>0.05). CONCLUSION: There might be roles of susceptive HLA- A*01: 01: 01: 01, A*03: 01, A*01: 01, A*02: 07 genotypes and protective effects of HLA-A*02: 01, A*11: 01 genotypes in the occurrence of Hodgkin's lymphoma in Xinjiang Uygur patients.",

Methods: EBV-encoded small RNA (EBER) was detected in 40 cases of HL and 20 cases of lymphoid reactive hyperplasia by in-situ hybridization. Expression of LMP2A in HL was investigated by immunohistochemistry. Results: EBV was detected in 26/40(65. 0%) of HL and 5/20 of lymphoid reactive hyperplasia (P < 0. 05). The expression level of EBER showed significant difference among various histological subtypes of HL (P < 0. 05) and between patients with and without B symptom (P = 0. 02). However, no difference was found in relation to gender, clinical stage and tumor burden. The expression of LMP2A in the mixed cellularity and nodular sclerosis classical HL associated with EBV infection was 57. 7% (15/26). Expression of LMP2A was not detected in lymphoid reactive hyperplasia cases. Conclusion: Uyghur patients with Hodgkin's lymphoma have a high infection rate of EBV and distinct clinicopathologic characteristics.",

        "abstract": "A platinum-based two-drug regimen is currently the standard of care for patients with advanced non-small-cell lung cancer (NSCLC). However, chemotherapy-induced side effects still remain a significant clinical problem. Astragalus polysaccharide (APS) is a polysaccharide isolated from the radix of astragalus membranaceus, a commonly used herbal compound in traditional Chinese medicine. APS was reported to increase tumor response, stabilize and improve performance status, and reduce chemotherapy toxicity. We designed this trial to determine whether APS injection integrated with vinorelbine and cisplatin (VC) offered an improved QOL over VC for patients with advanced NSCLC. Secondary objectives were tumor response, toxicity, and survival results. One hundred thirty-six patients with histologically or cytologically confirmed NSCLC were enrolled in this study from May 2008 to March 2010. Patients were randomized to receive either VC (VC arm) or VC combined with APS (VC-APS arm). The objective response rate of was 42.64% in the VC-APS arm and 36.76% in the VC arm. The difference was not statistically significant (P = 0.483). Median survival time was 10.7 and 10.2 months (P = 0.76) in VC-APS arm and VC arm, with 1-year survival rates of 35.3 and 32.4% (P = 0.717), respectively. After 3 cycles of treatment, there were significant differences in the overall patient QOL (P = 0.003), physical function (P = 0.01), fatigue (P < 0.001), nausea and vomiting (P < 0.001), pain (P = 0.007), and loss of appetite (P = 0.023) between the two study groups. In summary, we have proved that the treatment of APS integrated with VC had significantly improved QOL in patients with advanced NSCLC compared with VC alone. \u00a9 Springer Science+Business Media, LLC 2011.",

        "abstract": "Chemoresistance is a poor prognostic factor in breast cancer and is a major obstacle to the successful treatment of patients receiving chemotherapy. However, the precise mechanism of resistance remains unclear. In this study, a pair of breast cancer cell lines, MCF-7 and its adriamycin-resistant counterpart MCF-7/ADR was used to examine resistance-dependent cellular responses and to identify potential therapeutic targets. We applied nanoflow liquid chromatography (nLC) and tandem mass tags (TmT) quantitative mass spectrometry to distinguish the differentially expressed proteins (DEPs) between the two cell lines. Bioinformatics analyses were used to identify functionally active proteins and networks. 80 DEPs were identified with either up- or down-regulation. Basing on the human protein-protein interactions (PPI), we have retrieved the associated functional interaction networks for the DEPs and analyzed the biological functions. Six different signaling pathways and most of the DEPs strongly linked to chemoresistance, invasion, metastasis development, proliferation, and apoptosis. The identified proteins in biological networks served to resistant drug and to select critical candidates for validation analyses by western blot. The glucose-6-phosphate dehydrogenase (G6PD), gamma-glutamyl cyclotransferase (GGCT), isocitrate dehydrogenase 1 (NADP+,soluble)(IDH1), isocitrate dehydrogenase 2 (NADP+,mitochondrial) (IDH2) and glutathione S-transferase pi 1(GSTP1), five of the critical components of GSH pathway, contribute to chemoresistance.",

        "abstract": "The usual approaches to unmanned air vehicle(UAV)-to-ground target geo-location impose some severe constraints to the system, such as stationary objects, accurate geo-reference terrain database, or ground plane assumption. Micro air vehicle(MAV) works with characteristics including low altitude flight, limited payload and onboard sensors' low accuracy. According to these characteristics, a method is developed to determine the location of ground moving target which imaged from the air using monocular camera equipped on MAV. This method eliminates the requirements for terrain database (elevation maps) and altimeters that can provide MAV's and target's altitude. Instead, the proposed method only requires MAV flight status provided by its inherent onboard navigation system which includes inertial measurement unit(IMU) and global position system(GPS). The key is to get accurate information on the altitude of the ground moving target. First, Optical flow method extracts background static feature points. Setting a local region around the target in the current image, The features which are on the same plane with the target in this region are extracted, and are retained as aided features. Then, inverse-velocity method calculates the location of these points by integrated with aircraft status. The altitude of object, which is calculated by using position information of these aided features, combining with aircraft status and image coordinates, geo-locate the target. Meanwhile, a framework with Bayesian estimator is employed to eliminate noise caused by camera, IMU and GPS. Firstly, an extended Kalman filter(EKF) provides a simultaneous localization and mapping solution for the estimation of aircraft states and aided features location which defines the moving target local environment. Secondly, an unscented transformation(UT) method determines the estimated mean and covariance of target location from aircraft states and aided features location, and then exports them for the moving target Kalman filter(KF). Experimental results show that our method can instantaneously geo-locate the moving target by operator's single click and can reach 15 meters accuracy for an MAV flying at 200 meters above the ground. \u00a9 2011 SPIE.",

Motion vectors between frames were estimated by biological vision based feature matching algorithm. And then, a mathematical model of image transform parameters passing was proposed. In motion compensation phase, absolute displacement curves and rotation vectors were filtered by constraint interacting multiple model Kalman filter (CIMMKF) with hard constraint and soft constraint. Hard constraint was used to reduce errors induced by model inaccurateness, while soft constraint was used to smooth local skips caused by hard constraint. A novel method was proposed to evaluate the performance of video stabilization algorithm for micro air vehicle platform. Experiment results show that this video stabilization method can adapt to micro air vehicles' motion state variation, preserve intended motion, reduce filter delay effectively, and eliminate image high frequency jitter. The quality of stabilized videos can be satisfied by ground operators. This method is real-time and effective, especially appliable to micro air vehicle video stabilization.",

The measurements of onboard inertial measurement unit (IMU) sensors such as gyros and accelarometers are corrupted by large accumulated errors, and GPS signal is unavailable in such situation. Therefore, a monocular vision based indoor MAV motion estimation and structure recovery method is presented. Firstly, the features are tracked by biological vision based matching algorithm through the image sequence, and the motion of camra is estimated by the five-point algorithm. In the indoor environment, the planar relationship is used to reduce the feature point dimentions from three to two. Then, these parameters are optimized by an local strategy to improve the motion estimation and structure recovery accuracy. The measurements of IMU sensors and vision module are fused with extended Kalman filter. The attitude and position information of MAVs is estimated. The experiment shows that the method can reliably estimate the indoor motion of MAV in real-time, and the recovered environment information can be used for navigation of MAVs.",

Firstly, the optical flow histgram algorithm extracts background features in the target's local region. Secondly, these features are clustered into two possible classes including aided plane features and non-aided plane features by the expectation maximization algorithm, in which the homography relationship between MAV's flight status measured by onboard micro electro mechanical systems (MEMS)/global positioning system (GPS) sensors and planar is used. Meanwile, the normal vector of aided plane and the distance between the camera and the plane are estimated. Then the aided plane equation can be establised. Finally, the moving taregt can be geolocated by calculating the intersection of target's sight line and aided plane in inertial frame.

Hydrophilic poly(urea-formaldehyde) was employed as a wall-former, which tended to cure into solid on the exterior layer of the primary W/O emulsion containing chlorophyll in the oil phase as a core substance to generate microcapsules. In particular, the resultant poly(urea-formaldehyde) microcapsules were carefully characterized by UV-3600 UV-Vis-NIR spectrophotometer. The results indicated that the resultant green poly(urea-formaldehyde) microcapsules exhibited very similar spectral reflectance characteristics to leaves, and the similarity of the reflectance spectrum of green poly(urea-formaldehyde) microcapsules to that of plant leaves was up to 97.2% in the UV-Vis-NIR region of 300-2500 nm. In this regard, this new green poly(urea-formaldehyde) microcapsules is a promising candidate for materials with similar reflectance spectrum to leaves in the UV-Vis-NIR region of 300-2500 nm. The characterization of the microcapsules including FT-IR, SEM and FE-SEM were studied.

The climate pattern established during the uplift of the Qinghai-Tibet plateau and the descent of inland basins basically built up the distribution of desertified land in north China since Cenozoic. The climate in inland basins is arid, central China plateau is featured by semi-arid climate prominently controlled by the East Asian monsoon system while east China is dominated by worm and humid climate influenced by summer wind. The Quaternary climate variations have controlled desert expansion and reverse. Since last interglaciation, on going climate oscillations characterized by a 1 500 a cycle have dominated desertification in north China. Desertification at about 10, 000 a BP, 8, 000 a BP, 5, 500 a BP, 4, 000 a BP, 3, 000 a BP and 1, 500 a BP respectively corresponds to Numbers 7, 5, 4, 3, 2, and 1 floating ice events occurring in the North Atlantic Ocean, identical to the global climate fluctuation events. Cyclic climate changes at decade scale affect desertification to some extent, at least in some sensitive zones where the ecological environment is fragile. Cycliic climate oscillations at annual scale such as 6. 7a and 3. 38a may be important to dust storm. Furthermore, human activities are responsible for desertification expansion in many areas during last 150 years.",

To validate the modelling results of the microstructure, two load cases are intentionally designed to verify the microstructure for the view of comparing the results with homogeneous material under the same load cases. The whole process is carried out with the application of FEM. From the comparison of mechanical properties generated by the simulated microstructure with anisotropic material property to the ones showed by macrostructure with homogeneous material property, the validity and convenience of the modelling process is shown. The simulated microstructure for polycrystalline materials can be used for the further research on the initiation and growth of short fatigue cracks.",

Firstly, the microstructure is simulated to account for the effects of grain misorientation on the performance of short cracks and the short cracks are initiated within the microstructure for the further investigation. The influence of grain misorientation is demonstrated by the change of neighboring grain orientations with an initiated short crack from 0\u00b0 to 180\u00b0. The effects of the grain boundary on the short crack with the crack arrested or retarded are described by the crack propagation until it approached the grain boundary. The results will give more useful information such as crack arrested and retardation to the further research on the characteristics and evolution of short cracks.",

        "abstract": "Artificial joint replacement has been carried out in the youths and adults due to femoral necrosis, and the failure rate is obviously higher than those in cases due to other reasons, thus palliative therapy of preserving femoral head is strongly recommended before surgery to obtain the satisfactory effect, that is to prevent articular surface collapse and delay joint replacement. Totally 38 patients, including 34 adults of femoral necrosis and 4 children of epiphyseal ischemic necrosis, were adopted in the study at Department of Orthopaedics, the 463 Hospital of Chinese PLA from June 2005 to December 2006. They were all diagnosed pathologically after surgery. Each patient or their guardians signed an informed consent. Cord blood stem cells were donated by puerperant after full term normal delivery, which was offered by Beike Institute. Informed consents were obtained from all the puerperants, and this experiment was approved by the hospital ethical committee. Adult cases received the treatments, including synovectomy, femoral drilling, sequester erasion, grafting, blood vessel implant, and autogenous bone marrow stem cell transplantation. While the child cases were treated identically, except cord blood stem cell transplantation at the last step. At month 9 after surgery, radiography results showed the distinct femoral head, sclerotin and bone trabecula. A large amount of new bones were found in the femoral head, and collapse appeared obvious improvements, bone density was approximal to the normality; VAS score for pain decreased from 6.2 points before surgery to 2.2 points after surgery; Harris scores for hip joint function increased from (54.3 \u00b1 5.32) points before surgery to (89.6 \u00b1 10.5) points after surgery. No complications, such as vessel or nerve injuries, occurred in each patient. There was no adverse effect of the infection and hematoma in the blood collection area of iliac bone. It is indicated that the synovectomy, femoral drilling, sequester erasion, grafting, blood vessel implant, in combination with autogenous bone marrow stem cell transplantation can remarkably relieve the pain, promote the blood transport in the necrosis area, ameliorate the femoral bone density and improve the hip joint function in the femoral necrosis patients.",

        "abstract": "BACKGROUND: Synthetic bio-ceramics as good biological scaffolds can compound with autologous bone marrow stromal stem cells. Bone tissue engineering of their combination for bone graft brings a new hope for large bone defects. OBJECTIVE: To observe the therapeutic effects and feasibility of bio-ceramic combined with bone marrow stromal stem cells and bone morphogenetic protein in repair of large bone defects in rabbits. METHODS: Rabbit models of 1.5 cm-long bone defects were made by implanting the middle radial bone in the upper limbs. Left bone defect region served as the experimental group, implanting with bio-ceramic combined with bone marrow stromal stem cells and bone morphogenetic protein. Right bone defect region served as the control group, only implanting with bio-ceramic. At 4, 8, 12 and 24 weeks after model establishment, general observation was performed in both groups. Histological changes were observed with radiographs to compare the repair and healing in the bone defect region. RESULTS AND CONCLUSION: At 4, 8, 12 and 24 weeks after model establishment, compared with the control group, the repair of bone defects was faster, new bone formation was more, with complete plasticity, broken absorption was more apparent in the experimental group. At 24 weeks, bone defect region was completely bridged with broken ends of fractured bone. Bone was basically repaired. Results confirmed that bio-ceramic combined with bone marrow stromal stem cells and bone morphogenetic protein as graft materials in treatment of large bone defects of rabbits had a good therapeutic effect, and the effects were better than bio-ceramic alone.",

        "abstract": "Aim: Many studies have shown that Myostatin gene is detected not only in skeletal muscle but also in the heart of adult and mammary gland in embryonic period. On the contrary, some studies have suggested that the Myostatin expression is not found in heart, lung, brain, kidney and other tissues. This paper investigated the expression of Myostatin gene in different tissues of rats. Methods: The experiment was carried out in the Laboratory of Molecular Biology, Xinxiang Medical College from November 2006 to May 2007. The total Myostatin mRNA of lung, brain, skeletal muscle and heart tissue in 2-month-old SD rats of clean grade and 240 to 280 g were extracted using Trizol reagent and the expression was detected by semi-quantitative RT-PCR method. Results: In the lung, heart and skeletal muscle tissues, the expressions of myostatin were detected, and the expression in skeletal muscle was the highest. No was detected in brain. Conclusion: The expression of Myostatin is different in various tissues. It is predominantly expressed in skeletal muscle, and it is a differentially expressed gene.",

        "title": "Influence of tonifying kidney recipe on advanced glycation endproducts and lipid peroxidation in ovariectomized rats",
        "abstract": "Background: Previous studies have demonstrated that reduced estrogen levels may accelerate the formation of advanced glycation endproducts (AGE) in brain tissue, raise the concentration of lipid peroxidation products in vivo, and speed up deterioration of learning and memory. A tonifying kidney recipe is hypothesized to improve the ability of learning and memory in ovariectomized rats by downregulating AGE and lipid peroxidation products. Objective: To simulate a postmenopausal state, bilateral ovariectomy (OVX) was performed in rats, and the effects of tonifying kidney recipe (TKR) on AGE and lipid peroxidation in the rat cerebral cortex, hippocampus, and blood serum levels was measured. In addition, the effects on learning and memory were evaluated, and the effect of AGE -specific inhibitor aminoguanidine (AG) was compared with TKR. Design, time and setting: A randomized, in vivo, control experiment was performed at the scientific research center (Provincial Key Laboratory) in the Fourth Hospital of Hebei Medical University (Shijiazhuang, Hebei Province, China) from May 2005 to January 2007. Materials: Forty healthy, adult, female, Sprague Dawley rats were used for this study. TKR was composed of prepared rehmannia rhizome, epimedium herb, desert-living cistanche, and Szechwan lovage rhizome, which were provided by Shijiazhuang Medical Materials Company (China). A TKR extraction was prepared for further use. AG was provided by Sigma (USA). Forty rats were randomly divided into four groups: sham, OVX, AG, and TKR, with 10 rats in each group. Methods: The rat ovaries were resected in the OVX, AG, and TKR groups, whereas the same volume of fat was resected in the sham group. At four weeks after OVX, the AG group received 1% AG water solution by lavage; the TKR group was administrated by lavage once per day at a dose of 6.3 g (crude drug)/kg; OVX and sham groups received equal volumes of tap water. Main outcome measures: Learning and memory behavior of rats was tested in a Y-electric maze 16 weeks after the OVX procedure. The contents of advanced glycation endproducts in the rat cerebral cortex, hippocampus, serum, and urine were detected by competitive ELISA and spectrofluorophotometer. The contents of lipid peroxidation in rat serum, cerebral cortex, and hippocampus were assayed using a biochemical method. Results: Compared with the sham group, serum content of advanced glycation endproducts in the OVX group was significantly increased, and lipid peroxidation content increased in cerebral cortex, hippocampus, and serum (t = 3.04-4.22, P < 0.05-0.01). Both AG and TKR decreased the amount of AGE in cerebral cortex and serum (t = 2.53, 3.64, P < 0.05, 0.01), increased AGE urine content (t = 3.25-4.87, P < 0.01), and decreased lipid peroxidation content in cerebral cortex, hippocampus, and serum (t = 2.80-3.70, P < 0.05-0.01). In comparison to the OVX and sham groups, the correct escape rate in the Y-electric maze was significantly increased (t = 3.46, 3.28, P < 0.01), and escape latency was significantly decreased (t=3.12, 2.48, P < 0.05) in the AG and TKR groups, which indicated that both AG and TKR improved learning and memory. The OVX group had a significantly lower correct escape compared with the sham group (t = 4.21, P < 0.01). Conclusion: The tonifying kidney recipe decreased deposition of advanced glycation endproducts and lipid peroxidation in ovariectomized rats, and concomitantly improved learning and memory. The effect of TKR was equal to that of AG.",

Methods: There are 44 acute leukemia(AL) patients, among them ANLL is 29, ALL is 15. The expression of p170, MRP, bcl-2 were detected. At last, the patients were divided into two groups: CR and NR according to efficacy after two periods standard chemotherapy. Results: Overexpression of p170, MRP, bcl-2 were found in AL (P <0.05). The expression of p170 and MRP were lower in CR group than that in NR groups in AML and ALL; there were 22 of 24 patients expressed one or two proteins in NR groups and the expression of p170 in patients was concordant with that of MRP to certain extent (P <0.01). The overexpression of bcl-2 was related with the worse prognosis. The expression of bcl-2 was lower significantly in CR group than in CR and NR (P <0.05). Conclusion: p170, bcl-2, MRP are all associated with clinical MDR. High expression of these proteins is an unfavorable factor to prognosis. The expression of MRP and p170 showed coincidence, but showed no significance with expression of bcl-2 in untreated patients, it indicated that the drug-resistance mediated by p170 was different from bcl-2.",

        "abstract": "GATA transcription factor family members have been found to involve in the growth and differentiation of mammary gland. Among them GATA-3 is regarded as the most critical regulator involving the tumorigenesis of breast cancer (BC). Recently, trichorhinophalangeal syndrome-1 gene (TRPS-1), a new GATA family member, has been identified to be highly prevalent in breast cancer. Compared with ER-negative breast cancer, the expression of TRPS-1 is higher in ER-positive breast cancer and was significantly correlates with estrogen receptor, progesterone receptor, and GATA-3, indicating it may serve as a ductal epithelial cell-specific regulator in the differentiation of breast ductal epithelial cells. Studies have shown that miR221/222 is able to downregulate the expression of an epithelial cell marker E-cadherin by targeting TRPS-1, resulting in mammary epithelial cells transition to mesenchymal cell (EMT). In addition, it has been well accepted that TRPS-1 plays a role in the differentiation of several other cell types including kidney nephric mesenchymal cells, columnar chondrocytes, and osteoclasts, indicating that TRPS-1 involves in mesenchymal-to-epithelial cell transition (MET). In this article, we summarize the roles of GATA transcription factor TRPS-1 in ductal epithelial cells and the roles of its gene and protein expressions in predicting the prognosis of breast cancer.",

Through analyzing the gray characteristics of the image of the UAV, the new algorithm changed the judge criteria of the SUSAN corner detection algorithm to increase the accuracy and velocity of the image processing. The basic steps of the algorithmic show as follow: First, the correct threshold is decided using the gray characteristic. Second, comparing the one pixel with the eight neighborhood pixels, the elementary direction of corner is acquired. Last, a corner is acquired through calculating the number of the congener pixels based on these new directions. Using this new algorithm the corners should be detected fast and efficiently. Experimental results of the UAV video image processing show that the new method can highly increase computational velocity. Consequently the proposed algorithm meets the need for real-time image processing.",

Their extensive studies are important in both mathematics and physics with broad connections and applications. In contrast, very little is known about the special values of multiple zeta functions at non-positive integers since the values are usually undefined. We define and study multiple zeta functions at integer values by adapting methods of renormalization from quantum field theory, and following the Hopf algebra approach of Connes and Kreimer. This definition of renormalized MZVs agrees with the convergent MZVs and extends the work of Ihara-Kaneko-Zagier on renormalization of MZVs with positive arguments.

        "abstract": "A long standing problem of Gian-Carlo Rota for associative algebras is the classification of all linear operators that can be defined on them. In the 1970s, there were only a few known operators, for example, the derivative operator, the difference operator, the average operator and the Rota-Baxter operator. A few more appeared after Rota posed his problem. However, little progress was made to solve this problem in general. In part, this is because the precise meaning of the problem is not so well understood. In this paper, we propose a formulation of the problem using the framework of operated algebras and viewing an associative algebra with a linear operator as one that satisfies a certain operated polynomial identity. To narrow our focus more on the operators that Rota was interested in, we further consider two particular classes of operators, namely, those that generalize differential or Rota-Baxter operators. With the aid of computer algebra, we are able to come up with a list of these two classes of operators, and provide some evidence that these lists may be complete. Our search have revealed quite a few new operators of these types whose properties are expected to be similar to the differential operator and Rota-Baxter operator respectively. Recently, a more unified approach has emerged in related areas, such as difference algebra and differential algebra, and Rota-Baxter algebra and Nijenhuis algebra. The similarities in these theories can be more efficiently explored by advances on Rota's problem. \u00a9 2011 ACM.",

        "abstract": "A long standing problem of Gian-Carlo Rota for associative algebras is the classification of all linear operators that can be defined on them. In the 1970s, there were only a few known operators, for example, the derivative operator, the difference operator, the average operator, and the Rota-Baxter operator. A few more appeared after Rota posed his problem. However, little progress was made to solve this problem in general. In part, this is because the precise meaning of the problem is not so well understood. In this paper, we propose a formulation of the problem using the framework of operated algebras and viewing an associative algebra with a linear operator as one that satisfies a certain operated polynomial identity. This framework also allows us to apply theories of rewriting systems and Gr\u00f6bner-Shirshov bases. To narrow our focus more on the operators that Rota was interested in, we further consider two particular classes of operators, namely, those that generalize differential or Rota-Baxter operators. These two classes of operators correspond to those that possess Gr\u00f6bner-Shirshov bases under two different monomial orderings. Using this framework and computer algebra, we are able to come up with a list of these two classes of operators, and provide some evidence that these lists may be complete. Our search has revealed quite a few new operators of these types whose properties are expected to be similar to the differential operator and Rota-Baxter operator respectively.Recently, a more unified approach has emerged in related areas, such as difference algebra and differential algebra, and Rota-Baxter algebra and Nijenhuis algebra. The similarities in these theories can be more efficiently explored by advances on Rota's problem. \u00a9 2012 Elsevier B.V.",

The first formula generalizes the decomposition formula of Euler and is similar to the restricted formula of Eie and Wei for MZVs with one strings of 1's. The second formula generalizes the previous results to the product of two MZVs with one and two strings of 1's respectively. \u00a9 2014.",

The construction is from the free Rota-Baxter algebra on the free differential algebra on the set modulo the differential Rota-Baxter ideal generated by the noncommutative integration by parts formula. In order to obtain a canonical basis for this quotient, we first reduce to the case when the set is finite. Then in order to obtain the monomial order needed for the Composition-Diamond lemma, we consider the free Rota-Baxter algebra on the truncated free differential algebra.

        "abstract": "Objectives: Through a systematic review, to summarize and describe various health security mechanisms of protecting financial risk from illness in low and middle income countries (LMICs), and to analyze causes that lead to different effects in financial risk protecting. Methods: Search words were chosen by both health policy experts and search coordinators after discussion and pilot. Twenty-four electronic databases, websites of 11 health institutions, and the search engine Google were searched. Any original study to evaluate the role of financial protection of health security mechanism in LMICs was included. Pre-designed data extraction form was used for collecting strategies and study method of included studies, and extracted information was analyzed and described. Results: Fifty-two studies were included, and 56 specific health security mechanisms were categorized into 6: community-based health insurance, social health insurance, health sector reform, subsidy, user fee, and new rural cooperative medical scheme (NRCMS) in China. Forty-two mechanisms had positive effect in financial protection, 6 were negative, 5 had no effect and the effect of the other 2 was unclear. Conclusion: Mechanisms that produced positive effect can be summarized as: setting up of co-payment rate, design of benefit packages, providing free care for vulnerable population, delivering primary health care directly in remote area, and Chinese NRCMS. Mechanisms to protect the poor from financial risk of illness include: government provides health insurance, providing free care and setting up different co-payment rate according to income. The failure of health security mechanisms can be ascribed the deviation from its original goal of health security mechanism design, due to various inner or external causes. \u00a9 2008 Editorial Board of Chin J Evid-based Med.",

The working principle is elaborated and the three parts of the system, the dual-probe, the step-controlled scanning stage and the computer controlling center are illuminated. The measuring range of the system is demarcated by measuring a known grating of 2000 line/mm. The 3D surface profile images in local morphology and entire profile of an annular gasket with inside and external diameter of 4 mm and 8 mm are given respectively.

The derivative spectra of the diagnostic absorption bands are derived from the spectra measured in the field and used as characteristic spectral variables. A correlation analysis was conducted for the nitrogen content of the vegetation samples and the first derivative spectrum and the estimation model of nitrogen content established by a multiple stepwise linear regression method. The spatial distribution of nitrogen content was extracted by a parameter mapping method from the Hyperion data which revealed the distribution of the nitrogen content.

The stability and low cost of molecularly imprinted polymers (MIPs) render them attractive for a broad range of applications. Currently, MIP technique has been widely used in chiral separation. In this study, a series of molecularly imprinted polymers for N-Carbobenzoxy-L-tryptophan (N-Cbz-L-Trp) synthesized in different conditions were prepared in a small scale to simulate the monolithic chiral stationary phases (CSPs) primarily. By coupling in situ processing and batch rebinding evaluation, the type of functional monomers, which likely to affect the chiral selectivity of MIPs, was investigated. It was found that a MIP comprising a mixture of functional monomer 4-vinylpyridine (4-VP) and porogen 1-dodecanol/toluene exhibited the highest binding capacity and chiral selectivity for N-Carbobenzoxy-L-tryptophan. Thereafter, the monolithic MIP synthesized in screened optimum condition is used as chiral stationary phase in HPLC, which shows favourable separating capacity. \u00a9 (2012) Trans Tech Publications, Switzerland.",

        "abstract": "Background: Performances of composite resin and binder have been modified greatly; however, marginal permeability between composite resin filling material and teeth has been not completely resolved yet. Marginal permeability is a major factor to influence long-term therapeutic effect of teeth. Objective: To evaluate the effect of surface sealants (Fortify light-cured) on the marginal permeability of composite resin filling. Design, Time and Setting: A contrast study was performed at the Department of Stomatology, the 458 Hospital of Chinese PLA between January and August 2008. Materials: A total of 45 premolars resulting in deformed extraction were collected in this study. A pore sized 3 mm \u00d7 3 mm \u00d7 2 mm was drilled at buccal cervical surface of each tooth. Jaw wall of cavity was located in enamel, and cervical wall in cementum. Fortify Light-Cured surface sealant was provided by Bisco Company, USA. Methods: All 45 teeth were randomly divided into three groups: surface sealants group, binder group, and blank control group, with 15 teeth for each group. Surface sealants group: the teeth were treated with SE-BOND for 20 s, thoroughly dried with moderate and light air flow, covered with binder, light-irradiated for 10 s, filled with SE-BOND composite resin, light-irradiated for 40 s, polished, filled with resin, thoroughly dried with moderate and light air flow, evenly covered with surface sealants, and light-irradiated for 20 s. Binder group: the treatment was the same as surface sealants group except covering with binder. Blank control group: the teeth were maintained in saline for 24 hours at 37 \u00b0C following polishing. Main Outcome Measures: Depth of composite resin filling material under somatotype microscopy; adhesion between resin and teeth under scanning electron microscopy. Results: Marginal permeability decreased in the surface sealants and binder groups. Kruskal-Wallis test indicated that there were significant differences in marginal permeability between the three groups (P < 0.05). Furthermore, marginal permeability at coronal wall was lower than gingival wall, but there was no significant difference between the two sides (P > 0.05). Scanning electron microscopy indicated that adhesion was great in the surface sealants group; a leakage was observed in the binder group; the leakage in the blank control group was wider than binder group. Conclusion: The application of surface sealants can effectively decrease the marginal permeability.",

The Cr (VI) reduction rate can be greatly accelerated when low-molecular-weight organic acid is present. This process of photoreduction follows approximately zero order kinetics. The effects of pH values on the reduction efficiency are also investigated. The photoreduction efficiency of chromium is higher under acidic pH than that of in the weakly alkaline pH. The photoreduction efficiency of Cr (VI) is found to increase with concentrations of organic carboxylic acids and montmorillonite. However, the reaction is independent of Cr (VI) concentration. \u00a92009 IEEE.",

The inclusion interaction of \u03b1- and \u03b2-cyclodextrin with BPS was ascertained by UV/Vis spectrophotometer. The influence of complexation with \u03b2-CD was found to enhance the light-induced decomposition of BPS and that of \u03b1-CD inhibited BPS photodegradation, however P-CD inhibits photomineralization of BPS. The kinetics of BPS photocatalytic degradation with different BPS initial concentrations was investigated by first-order reaction model. The experiments demonstrated that the change of pH and \u03b2-CD initial concentration could significantly affect the photodegradation of BPS. The effects of cyclodextrin inclusion complexation on photoreaction rate of BPS were also discussed on the basis of experimental data.",

The function of the environmental and technological innovation in the eco-industrial management becomes more and more important, but the research on how an important role the environmental and technological innovation plays has not bean really carried out. The study attempted to establish the double logarithmic regression equation consisting of input variables and output variable of eco-industrial management. The output variable was the industrial eco-efficiency and the input variables were signified by the environmental and technological innovation, the environmental policy, the environmental investment and the environmental human resource. Thus the influencing degree of the environmental and technological innovation on the eco-industrial management in China was empirically explored. The results showed that the role of the environmental technological innovation in eco-industrial management was weak and the situation was even worse in mid-west region of China. However, if the industrial innovation were altogether put into EIM, the input of environmental capital and policy and personnel should all be rapidly reduced. The paper draw the conclusion that how to make the environmental and technological innovation play the full function is an urgent issue in the present eco-industrial development in China.",

        "abstract": "Objective: To investigate the scientificity of patient-reported outcome (PRO) scale for myasthenia gravis (MG), which was used to evaluate the clinical effects of traditional Chinese and Western medicine treatment on MG patients. Psychometric performance of the MG-PRO scale was also expected to be evaluated in this study. Methods: A total of 100 MG patients and 100 healthy people were face-to-face interviewed by well-trained investigators, and the data of MG-PRO scale were collected. The classical theory test (CTT) and item response theory (IRT) methods were used to analyze the psychometric performance such as validity, reliability, person separation index (PSI) and differential item functioning (DIF) in the MG-PRO scale. Results: The results of CTT analysis showed that the split-half reliabilities of the MG-PRO scale and each dimension were greater than 0.7. In the analysis of internal consistency of each dimension, the Cronbach's a was greater than 0.8. Each facet had greater correlation with its dimension than the other dimensions. Four principal components were extracted by exploratory factor analysis, which represented all dimensions of the scale, and the cumulative variance was 55. 54%. The scores of each of the 8 facets between MG patients and healthy people were different ( P <0. 01). The results of IRT showed that the PSI of each model was greater than 0.8, and all items did not have uniform DIF and non-uniform DIF. Conclusion: The MG-PRO scale reflects the definition and connotation of quality of life and contains special issues of MG patients as well, and shows good reliability (split-half reliability, Cronbach' s \u03b1) validity (content validity, construct validity, discriminate validity) from the results of CTT, and good psychometric performance from the results of IRT.",

Methods: A total of 100 MG patients were interviewed for the field testing. Another 56 MG patients were selected and assessed with the MG-PRO scale before treatment and at 1, 2 and 4 weeks after treatment. The classical test theory and item response theory (IRT) were used to assess the psychometric characteristics of the MG-PRO scale. Results: The MG-PRO scale included 4 dimensions: physical, psychological, social environment, and treatment. Confirmatory factor analysis showed that each dimension was consistent with the theoretical construct. The scores of the physical and psychological dimensions increased significantly at 1 week after treatment (P<0.05). All the dimension scores and the MG-PRO score increased significantly at 2 and 4 weeks after treatment (P<0.05). IRT showed that person separation indices were greater than 0.8, most of the item fit residual statistics were within \u00b12.5, and no item had uniform or non-uniform differential item functioning (DIF) between gender and age (<40, 40). Conclusions: The MG-PRO scale is valid for measuring the quality of life (QOL) of MG patients, with good reliability, validity, responsiveness, and good psychometric characteristics from IRT. It can be applied to evaluate the QOL of MG patients and to assess treatment effects in clinical trials. \u00a9 2011 The Chinese Journal of Integrated Traditional and Western Medicine Press and Springer-Verlag Berlin Heidelberg.",

        "abstract": "Nonlethal mechanical trauma causes cardiomyocyte apoptosis which contributes to posttraumatic cardiac dysfunction. Apoptosis is positively correlated with protein nitration in the traumatic heart. However, the mechanisms responsible for the cardiomyocyte protein nitration remain unclear. The present study was designed to identify whether myeloperoxidase may contribute to protein nitration in nonlethal mechanical trauma and subsequent cardiomyocyte apoptosis, and, if so, to determine the possible mechanisms responsible. We used Noble-Collip drum to make nonlethal traumatic mice models. Male adult C57B16/J mice were placed in the Noble-Collip drum and subjected to a total of 200 revolutions at a rate of 40 r/min. Then myeloperoxidase activity and release, protein nitration, cardiomyocyte apoptosis, endothelial function and intercellular adhesion molecule-1 expression were determined. Nonlethal mechanical trauma was characterized by the 100% survival rate during the first 24 h after trauma, the lack of circulatory shock and without direct heart injury. However, myeloperoxidase activity significantly increased 6 h after trauma, and reached a maximum level 12 h after trauma. Obviously, protein nitration and cardiomyocyte apoptosis increased 12 h after trauma and could be blocked by administration of R15.7, a monoclonal antibody that blocks polymorphonuclear neutrophils adhesion. Moreover, endothelial dysfunction and intercellular adhesion molecule-1 upregulation were observed in traumatic mice. Our present study demonstrated for the first time that myeloperoxidase caused protein nitration and cardiomyocyte apoptosis in nonlethal traumatic mice. Inhibition of polymorphonuclear neutrophils adhesion and antinitration treatments may be novel measures in reducing posttraumatic cardiomyocyte apoptosis and secondary heart injury. \u00a9 2010 Elsevier Inc.",

Neural tube defects tend to occur with a high rate in Shanxi province, China. The present case-control study investigated genotypic distributions and allele frequencies of Slug C1548A polymorphisms in DNA samples from 59 women with a history of neural tube defect pregnancies and 73 controls during the same period from Shanxi Province, China. Results demonstrated that women with a history of neural tube defect pregnancies had significantly greater genotypic distributions of Slug AA genotypes and A allele frequencies compared with controls, and A allele Slug C1548A was a risk factor for neural tube defects (odds ratio = 3.444; 95% confidence interval: 2.021-5.868, P < 0.05). Three-dimensional structure prediction revealed that Slug C1548A resulted in transition of aspartic acid into glutamate at position 119. This indicated that these mutations could lead to damaged protein structure and function. These findings suggest that Slug C1548A gene polymorphism is closely related to neural tube defects in a population of Han Chinese origin from Shanxi Province, China.",

        "abstract": "Aim: To examine whether iNOS contributes to endothelial dysfunction in aged rats. Methods: Male Sprague Dawley rats were divided into three groups: young rats, aged rats treated with vehicle and aged rats treated with N-[3-(Aminomethyl) benzyl] acetamidine (1400W, 1 mg/kg, ip). Vasorelaxation was measured in isolated thoracic aorta. iNOS expression of thoracic aortic arteries was detected using immunohistochemistry and Western blot. Nitrotyrosine (a marker for peroxynitrite formation) content and expression in thoracic aortic tissue were determined using enzyme linked immunosorbent assay and immunohistochemistry. Results: Maximal relaxation induced by acetylcholine (10-9 to 10-5 mol/L) in the aged rats treated with vehicle was significantly decreased (70%15%, P0.01), as compared with the young rats (95%8%). However, the maximal relaxation induced by acidified NaNO2 (an endothelium-independent vasodilator) had no significant difference between the two groups. Moreover, iNOS and nitrotyrosine expression increased in the vessels of the aged rats. In the aged rats treated with 1400W (a highly selective iNOS inhibitor) nitrotyrosine expression was reduced and acetylcholine-induced vasorelaxation was markedly improved (maximal relaxation was increased to 87%8%, P0.05), but the acidified NaNO 2-induced vasorelaxation had no significant change.Conclusion:Our study demonstrated that inhibition of iNOS by 1400W increased endothelium-dependent vasodilation in aged rats. The mechanism was related with attenuation of peroxynitrite formation. \u00a9 2010 CPS and SIMM All rights reserved.",

        "abstract": "Background Neural tube defects are the most common human birth defects. The causes are multifactorial with complex genetic and environmental factors, although the exact genetic causes are unknown. This research was conducted to study the frequency of Msx2 gene polymorphisms in 59 women with a history of pregnancy with a neural tube defect and in 73 healthy controls. We aimed to determine the effect of this genetic polymorphism on the incidence of neural tube defects in the Han Chinese population. Methods We studied 59 mothers with at least one previous child with a neural tube defect (the case group) and 73 case-control subjects during the same period, from Shanxi Province, China. We analyzed the genotypic distributions and allele frequencies of Msx2 C386T polymorphisms in DNA samples from the case and control groups. A three-dimensional protein model was predicted using Swiss-Pdb Viewer software version 4.0. Disease association was analyzed using chi-square tests. Results Significant differences were observed in the genotypes and allele frequencies of the Msx2 C386T allele between the case and control groups (CT: 32% vs. 15%, P=0.0073 and TT 15% vs. 4%, P=0.013, respectively). Logistic regression analysis showed that the C386T mutation is a potential risk factor for neural tube defects (P <0.05; OR: 3.466; 95%CI: 1.831-6.560). Three-dimensional structure prediction revealed that the Msx2 C386T mutation results in a threonine substitution for methionine at position 129 of exon 2, which might lead to structural mutations or dysfunctions in the protein encoded by Msx2. Conclusion Maternal Msx2 C386T gene polymorphisms were associated with fetal neural tube defects in Han Chinese women in Shanxi Province.",

Methods: Bronchoalveolar lavage fluid (BALF) was obtained from 7 asthmatic patients and 7 healthy control individuals. The percentage of \u03b3\u03b4T cell in BALF was measured by flow cytometry. The \u03b3\u03b4T cell in BALF was purified by magnetic labeled beads. Proliferous activity was examined by MTT assay. Cytokines secreted by \u03b4\u03b4T cells in medium was assessed by enzyme-linked immunosorbent assay. Polymorphism of T cell receptor V\u03b4 chain was detected by RT-PCR and genescan analysis. Results: The proportion of \u03b4\u03b4T cell in the BALF of asthmatic patients [(6.39 \u00b1 0.71)%] was significantly higher than that in control subjects [(2.62 \u00b1 0.37)%] (P < 0.01). The proportion of macrophage in the BALF of asthmatic patients [(81 \u00b14)%] was significantly lower than that in control subjects [(86 \u00b1 2)%] (P < 0.05). The proliferation rate of asthmatic patients [(284.2 \u00b1 43.6)%] was significantly higher than that of control subjects [(217.5 \u00b1 59. 5)%] (P < 0.05). Interleukin-4 secreted by \u03b4\u03b4T cells of asthmatic patientts [(18.9 \u00b1 3.1) pg/ml)] significantly increased when compared with the control subjects [(14.1 \u00b1 3.0) pg/ml] (P < 0.05). The polymorphism of T cell receptor V\u03b4 chain was not significantly different between these two groups.

To further elucidate the functions of TPS to starch-based foods, experiments were carried out using mixed amylose/amylopectin/TPS system as a model. The effects of TPS in green tea on the glass transition temperatures (Tgs) of the mixtures with different amylose/amylopectin ratios at low water contents were investigated using high-speed differential scanning calorimetry (Hyper-DSC). The results showed that the Tgs of amylose, amylopectin and their mixtures decrease with increasing concentration of TPS. It is suggested that the addition of TPS has plasticizing effects on the structures of amylose and amylopectin on the molecular level. Based on the molecular characteristics of TPS, the results in this study indicated that TPS is a homogeneous and spherical polymer with branch in solution, which can increase free volume and molecular movement of amylose and amylopectin chains. TPS can also produce greater electrostatic repulsion and decrease association among macromolecules, thereby resulting in the decrease of the Tgs of amylose, amylopectin and their mixtures. \u00a9 2010.",

Furthermore, dual-modification of starches - enzyme hydrolyzed starch followed by cross-linking as well as enzyme hydrolysis upon cross-linking was explored. The results suggested that enzyme hydrolyzed starch followed by cross-linking was significantly different from enzyme hydrolysis upon cross-linking. The granular specific surface area of the dual-modified starches was more than thousand orders of native corn starch. Crosslinked starch phosphates and enzyme hydrolyzed starch followed by cross-linking had higher gelatinization temperature than porous starch and cross-linked starch followed by enzyme hydrolysis. The \u0394H of crosslinked starch phosphates and dual-modification of starches were larger than that of native corn starch and porous starch, which indicates that the cross-linking strengthens the starch granules and hence more energy is required for disruption. The absorption capacities of enzyme hydrolyzed starch followed by cross-linking and enzyme hydrolysis upon cross-linking were 5 times more than that of native corn starch, crosslinked starch phosphates and porous starch. Overall, it is concluded that the combination of cross-linking and enzyme hydrolysis is a favorable approach to increase the mechanical strength and adsorptive capacity of porous starches.",

The results showed that the K<inf>m</inf> values of the native and gelatinized starch were 10.35 mg/mL and 9.92 mg/mL, respectively. The digestion rate coefficients k values of the native and gelatinized starches were 2.0 \u00d7 10<sup>-3</sup> min<sup>-1</sup> and 1.1 \u00d7 10<sup>-2</sup> min<sup>-1</sup>, respectively. The contents of rapid digestible starch (RDS), slowly digestible starch (SDS) and resistant starch (RS) in native glutinous rice starch were 8.92%, 21.52% and 69.56%, respectively. After gelatinization, the amounts of RDS, SDS and RS were 18.47%, 29.75% and 51.78%, respectively. The native and gelatinized glutinous rice starches were 10.34% and 14.07% for hydrolysis index (HI), as well as 43.14% and 45.92% for glycemic index (GI), respectively. During the in vitro digestion, the crystallinity of native glutinous rice starch was increased from 34.7% to 35.8% and 38.4% after 20 and 120 min, respectively.",

Then the IWRLS algorithm is made to achieve updating model parameters at real-time. On this basis, in order to reflect the physical meaning and complete the filtering operation at the same time, a statistical model and ARMA are introduced into the Kalman filter equations. In the equations, state equation is established by self-variable which reflects the state characteristics with ARMA, and observation equation is established by dependent variable which reflects physical meaning with statistical models. So considering the white noise, the time-varying Kalman prediction model is established with the comprehensive functions. Case analysis shows that the fitting and forecast accuracy of time-varying Kalman model are superior to those traditional statistical models.",

In this paper the thermal conductivity of the nanofluid is studied by an equilibrium molecular dynamics simulation. The property of molecular layering at liquid-solid interface and its effect on the thermal conductivity of the nanofluid are also investigated. By tracking the position of the nanoparticle and the liquid atoms around the spherical nanoparticle, it was found that a thin layer of liquid is formed at the interface between the nanoparticle and liquid. In the liquid layer the atoms are more crowded than in base fluid and then they will collide more frequently and transfer more energy. Consequently the thermal conductivity of the nanofluid is enhanced. Through the analysis of the density distribution of the liquid near the nanoparticle the thickness of the layering is calculated under the parameters used in this paper.",

The effects of different temperatures from 25\u2103 to -60\u2103 on microstructure and phases of the alloy, the tensile strength and the low cyclic fatigue resistance of the welded junction were studied. The results show that under low temperature condition tin pest is non-occurrence in SnAg3.0Cu0.5 solder. The solder is mainly composed of Ag3Sn and \u03b2-Sn phases, the morphology turns to dendritic structure with definite orientation. The crystalline interplanar spacing of \u03b2-Sn decreases, which leads to a low temperature brittleness tendancy. The fractures in SnAg3.0Cu0.5/Cu interface are moving from the solder to the copper side with decreasing temperature, which can reduce the tensile strength of the welded joint. Under constant strain condition, the slope of tensile load-cycle curves increase with the decreasing temperature, which decreases the fatigue resistance of welded joint.",

With the rapid development of dating technology, the establishment of long dated sequences of sediments has become possible. Through observing the core of unconsolidated strata, this paper divided the core into 8 characteristic lithologie sections on the basis of the characteristics of sediment color, sedimentary environment, cycle and structure. Also, the result of paleomagnetism dating shows that 0-96.59 m of core is the Brunhes Normal Polarity Zone, 96.59-246.79 m is the Matuyama Reversed Polarity Zone, and 246.79-413.64 m is the Gauss Normal Polarity Zone. By mean of pollen analysis and a comparison with the evolution history of Cenozoic climate in North China, the authors hold that the depth of 246.5 m can be regarded as Q/N boundary, the depth of 534.5 m is N/E boundary, and the depth of 803.4 m is E/K boundary. Based on the principle of magnetic and climatic stratigraphy with the aid of rock stratigraphy, the authors studied the new No. 5 borehole and divided Cenozoic stratigraphie sequence into the late, middle and early Pleistocene, with Q/N boundary located at the depth of 248.4 m, N/E at the depth of 511.9 m, and E/K at the depth of 804.1 m.",

The first case is an ordinary retaining wall without expanded polystyrene (EPS) geofoam buffer. In the second and the third case, a layer of vertical EPS buffer with different density and elastic modulus is placed between a rigid retaining wall and backfill soil. Numerical simulation results show that the force against the same retaining wall in the treated cases is less than that in the untreated case, under both static loads and vibration loads. Moreover, the compression of different EPS buffer is studied. Under vibration excitation, when the density and elastic modulus of EPS buffer decreases, its compression increases and more wall force is mitigated. Simulation results accord with the physical shaking table test data. Numerical results and physical test demonstrate that EPS geofoam seismic buffers hold great promise to reduce loads against rigid retaining wall structures, especially earthquake-induced dynamic loads. \u00a9 (2011) Trans Tech Publications.",

This study aimed to determine the relationship between CXCL12/CXCR4, CXCL16/CXCR6 and ovarian carcinomas clinicopathologic features and prognosis. Accordingly, the expression of these proteins in ovarian tissues was detected by tissue microarray and immunohistochemistry. The expressions of CXCL12/CXCR4 and CXCL16/CXCR6 were significantly higher in epithelial ovarian carcinomas than in normal epithelial ovarian tissues or benign epithelial ovarian tumors. The expression of chemokines CXCL12 and CXCL16 were positively correlated with their receptors CXCR4 and CXCR6 in ovarian carcinoma, respectively (r = 0.300, P < 0.05; r = 0.395, P < 0.05). Moreover, the expression of CXCL12 was related to the occurrence of ascites (\u03a7 ",

The system breaks through the limitation of traditional two-dimensional display and is independent of the development environment and current GIS platform, which can quickly provide decision support for the flood regulation and water storage.

The results indicate that there is significant correlation between total coverage of vegetation community and groundwater depth within 1.6m. The respective coverage of some wetland species has different peak values. It indicates that these species have certain ecological groundwater depth. The relation between species succession and groundwater depth shows that wet and saline vegetation are predominant when groundwater depth is less than 0.6m. xerophyte and sandy vegetation are predominant when groundwater depth is above 3.2m.

The study of mechanisms and modeling of the evaporation process has a very important practical significance in improving the isotopic analysis method. This paper reviews the international development of the mechanism of hydrogen and oxygen stable isotopic fractionation and model. It indicates that as the most ideal tracers of hydrologic cycle, stable hydrogen and oxygen isotopes have their unique and irreplaceable functions. However, field experiments of evaporation and further research are limited by the complexities of kinetic flow in the atmosphere and observation technique. Modeling and experiments are commonly based on the assumption that evaporating water is well-mixed, and isotopic stratification in liquid is not considered by most laboratories. While it dose affect. Flow disturbance in the atmosphere is the most uncertain factor for isotopic fractionation in the process of evaporation. The modeling example shows isotopic evaporation line of natural water can be simulated properly while detailed simulations are limited by the lake of observational data of isotopic diffusion processes in both air phase and liquid phase. \u00a9 (2012) Trans Tech Publications, Switzerland.",

        "abstract": "Groundwater plays a key role in arid regions as the majority of water is supplied by it. Groundwater pollution is a major issue, because it is susceptible to contamination from land use and other anthropogenic impacts. A study was carried out to build a vulnerability map for the Ordos Plateau using the DRASTIC model in a GIS environment. The map was designed to show the areas of the highest potential for groundwater pollution based on hydrogeological conditions. Seven environmental parameters, such as depth to water table, net recharge, aquifer media, soil media, topography, impact of the vadose zone media, and hydraulic conductivity of the aquifer, were incorporated into the DRASTIC model and GIS was used to create a groundwater vulnerability map by overlaying the available data. The results of this study show that 24. 8 % of the study area has high pollution potential, 24. 2 % has moderate pollution potential, 19. 7 % has low pollution potential, and the remaining 31. 3 % of the area has no risk of groundwater pollution. The regional distribution of nitrate is well correlated with the DRASTIC vulnerability index. In contrast to this, although the DRASTIC model indicated that the western part had no risk, nitrate concentrations were higher in some of these areas. In particular, higher nitrate concentrations were recorded along river valleys and around lakes, such as the Mulin River valley. This is mainly caused by the intensive agricultural development and favorable conditions for recharge along river valleys. \u00a9 2012 Springer-Verlag.",

The control role of aquifer system to groundwater flow system is studied by comparison of groundwater flow systems under the control of different aquifer structures in 2-D profile numerical model. The research shows that the groundwater flow systems of the Ordos basin have the multilayer structure characteristics. The groundwater flow systems in the north of the Ordos basin show a cross-formational multi-hierarchy nested flow pattern in the northern aquifer systems without regional impermeable layer where the hydraulic connection between aquifer layers is closely. While, the hydraulic connection is discontinuous in the southern aquifer systems because there are regional impermeable layers in the aquifer systems.

Exclusion criteria: (a) articles that required manual searching or telephone access; (b) documents that were not published in the public domain; and (c) corrected papers. MAIN OUTCOME MEASURES: (1) Annual publication output, distribution by journal, distribution by institution and top-cited articles on neural stem cells; (2) annual publication output, distribution by journal, distribution by institution and top-cited articles on Schwann cells; (3) annual publication output, distribution by journal, distribution by institution and top-cited articles on olfactory ensheathing cells. RESULTS: This analysis, based on articles indexed in the Web of Science, identified several research trends among studies published over the past 10 years in transplantation of neural stem cells, Schwann cells and olfactory ensheathing cells for spinal cord injury. The number of publications increased over the 10-year period examined. Most papers appeared in journals with a focus on neurology, such as Journal of Neurotrauma, Experimental Neurology and Glia. Research institutes publishing on the use of neural stem cells to repair spinal cord injury were mostly in the USA and Canada. Those publishing on the use of Schwann cells were mostly in the USA and Canada as well. Those publishing on the use of olfactory ensheathing cells were mostly in the UK, the USA and Canada. CONCLUSION: On the basis of the large number of studies around the world, cell transplantation has proven to be the most promising therapeutic approach for spinal cord injury.",

This article establishes the axial magnetic model through the equivalent magnetic charge method, but the equivalent magnetic charge method solving the axial force need work out four complicated quadruple integrals. The calculation cycle the traditional method is too long, and even cannot get analytical solution. On the contrary, the method of through Forcal language programming to approximate computation bearing axial force makes the solving process simplification. The stiffness of the permanent magnet bearing with equivalent magnetic charge method is verified by comparing the simulating result obtained by using the finite element method.

        "abstract": "Volatile compounds from Pu-erh tea were extracted using a headspace-solid phase microextraction (HS-SPME), and analysed with a gas chromatography-mass spectrometry (GC-MS) and a gas chromatography olfactometry (GC-O). Results showed that a total of 66 major volatile compounds were identified by GC-MS analysis; among them, methoxy-phenolic compounds (33.58%), alcohols (23.01%) and hydrocarbons (11.62%) were the major chemical classes. It was found that 1,2,3-trimethoxybenzene (17.16%) was the most abundant aroma components, followed by \u03b1-terpineol (5.68%), 1,2-dimethoxybenzene (4.64%) and linalool oxide II (4.29%) in order. Twenty-nine odour active compounds were perceived by GC-O analysis. Further investigation showed that 1,2-dimethoxybenzene, 1,2,3-trimethoxybenzene, 1,2,3-trimethoxy-5-methylbenzene, 4-ethyl-1,2- dimethoxy-benzene, \u03b2-ionone, \u03b2-linalool, linalool oxides, decanal, etc. were responsible for the special flavour in Pu-erh tea. It seems that the methoxy-phenolic compounds and alcohols play a vital role in the special flavour of Pu-erh tea. \u00a9 2011 Elsevier Ltd. All rights reserved.",

        "abstract": "The aim of the present study was to determine the causative agent of infected swines in the Jilin province of China and assess its genetic characteristics. Virus was isolated from tissues suspected of being infected by porcine reproductive and respiratory syndrome virus (PRRSV) and inoculated onto MARC-145 cells. Virus detection was carried out by RT-PCR, immunofluorescence, electron microscopy and sequencing. The results showed that the isolate was the North American genotype PRRSV, termed the JL-04/12 strain, with a 15,320 bp genome. The homology of the amino acid sequences in two nonstructural proteins and GP2 to GP5, between strains JL-04/12 and HUN4, ranged from 97.2 to 99.3 %. However, JL-04/12 GP6 and N protein were identical in HP-PRRSV JXA1 and HUN4. JL-04/12 was characterized by two discontinuous deletions in Nsp2. We speculate that the isolate is a variant of highly pathogenic porcine reproductive and respiratory syndrome derived from strains in 2006-2008. Altogether, these results indicate that highly pathogenic porcine reproductive and respiratory syndrome virus still exists in the Jilin province of China. \u00a9 2013 Indian Virological Society.",

The results revealed that four tea cultivars were found to contain higher levels of EGCG3\u2033Me (>10. mg/g). There were significant regional characteristics in the distribution features of these Chinese tea cultivars rich in EGCG3''Me. The levels of EGCG3\u2033Me were the highest in the third leaf among the tea leaves from different positions of young shoots with a bud and five leaves. The content of EGCG3\u2033Me increased distinctly during the withering process, whereas the content declined drastically during the fermentation process. Based on these results, a better way to produce tea leaves rich in EGCG3\u2033Me is proposed, which includes picking standards for fresh tea leaves and for processing methods. This study provides a solid foundation for the further exploitation and utilization of natural EGCG3\u2033Me in the food and pharmaceutical areas. \u00a9 2013 Elsevier Ltd.",

        "abstract": "Background: Bovine viral diarrhea virus (BVDV) is a pathogen found worldwide in calves. It can cause significant economic losses in agriculture. Many BVDV strains have been isolated in China. However, the pathogenesis and complete gene characteristics of BVDV isolate have yet not been reported in China. Here, a BVDV isolate was isolated and its pathogenesis and complete genome were studied. Results: A new isolate of bovine viral diarrhea virus, named JL-1, was isolated from the spleen of a sick cow with diarrhea using MDBK cell culture. The complete genome of JL-1 is 12,276 nucleotides and contains a 5\u2032-UTR of 382 nucleotides, a 3\u2032-UTR of 188 nucleotides, and a large ORF encoding a polyprotein consisting of 3,901 amino acids. Genomic comparison and phylogenetic analyses of complete genomic sequence clearly showed that JL-1 fell into the BVDV-1b subtype. The result of pathogenesis of JL-1 strain showed that all infected calves developed clinical signs of elevated rectal temperatures, decreased leucopenia, and viral discharge. Viral antigen was detected in infected animal tissues using immunohistochemistry. Animals in the mock were normal. These results demonstrated that BVDV JL-1 was a virulent strain. Conclusions: This is the first study to report the pathogenesis and complete gene characterization of the BVDV strain in China. This report may set a good foundation for further study of BVDV in China. \u00a9 2014 Zhang et al.; licensee BioMed Central Ltd.",

        "abstract": "Epigallocatechin-3-O-(3-O-methyl) gallate (EGCG3\u2033Me) present in leaves of Camellia sinensis has many beneficial biological activities for human health. However, EGCG3\u2033Me occurs naturally in tea leaves in extremely limited quantities. Finding an enzyme from C. sinensis to catalyze the synthesis of EGCG3\u2033Me is an alternative method to make up for the scarcity of EGCG3\u2033Me in natural situations. In the present study, a complementary DNA (cDNA) encoding region and genomic DNA of the caffeoyl-coenzyme A O-methyltransferase (CCoAOMT) gene were isolated from C. sinensis (designated CsCCoAOMT). Nucleotide sequence analysis of CsCCoAOMT revealed an open reading frame of 738 bp that encodes a polypeptide with a predicted molecular weight of 28 kDa, which correlated well with the results of sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The full-length DNA sequence (2678 bp) contained five exons and four introns. The deduced amino acid sequence of CsCCoAOMT shared 92% identity with CCoAOMTs from Codonopsis lanceolata and Betula luminifera. The catalytic activity of CsCCoAOMT was analyzed. Three monomethylated epigallocatechin-3-O-gallate (EGCG) compounds (EGCG4\u2033Me, EGCG3\u2033Me, and EGCG3\u2032Me) were produced by CsCCoAOMT with K",

        "abstract": "In the present study, the genotype of two Canine distemper virus (CDV) strains, namely, ZJJ-SD and ZJJ-LN, were investigated, based on the whole hemagglutinin (HA) gene. The CDV strains were obtained from two foxes in Shandong Province and Liaoning Province in 2011. Phylogenetic analyses were carried out for 260 CDV strains worldwide, and a statistical analysis was performed in the amino acid substitutions at positions 530 and 549 of the HA protein. Phylogenetic analyses revealed that the two strains, ZJJ-SD and ZJJ-LN, belonged to the CDV Asia I lineage. Site 530 of HA protein was found to be relatively conserved within CDV lineages in different host species by combining the genetic sequence data with the published data from 260 CDV strains worldwide. The data analysis showed a bias toward the predicted substitution Y549H for the non-dog strains in Asia I and Europe lineages. The ratio of site 549 genetic drift in the HA gene were significantly different between dogs and non-dogs in the two lineages. The strain ZJJ-SD, from wild canid, has an Y549H substitution. It is one of three Y549H substitution for wild canids in Asia I lineages. Site 530 of HA protein was not immediately relative to CDV genetic drift from dogs to non-dogs. Statistical analysis indicated that non-dog strains have a high probability to contain Y549H than dog strains in Asia I and Europe lineages. Thus, site 549 is considered important in genetic drift from dogs to non-dogs, at least in Asia I and Europe lineages.",

        "abstract": "Bovine parainfluenza virus type 3 (BPIV3) is one of the most important viral respiratory pathogens in both young and adult cattle. Nucleocapsid protein (NP) is the most abundant viral protein and the main regulator of virus replication and transcription. In this study, amino acid sequence data of BPIV3 NP was used to identify potential linear epitopic regions, which were subsequently used to design truncated recombinant NP antigens. The amino-terminal region (aa 9-157, NP-N) and the carboxy-terminal region (aa 391-500, NP-C) were selected, and these two truncated recombinant BPIV3 NP proteins were expressed in Escherichia coli based on the results of prediction studies. Furthermore, Enzyme-Linked Immunosorbent Assays (ELISAs) were established using the truncated recombinant BPIV3-N proteins as antigens, and 154 clinical samples were used to evaluate the newly established ELISA systems in comparison with a virus neutralisation test (VNT) as a reference. The results showed that a high coincidence rate was observed for the data that were obtained by the two methods. The sensitivity of NP-N ELISA and NP-C ELISA were 98.4% and 94.6%, respectively, and the specificity of both ELISAs was 100% with reference to the VNTs. Our data indicated that both ends of NP have high immunogenicity during BPIV3 infection and that they were good targets for serodiagnosis. The ELISAs based on the two truncated proteins were especially suitable for use in large-scale epidemiological investigations.",

Numerical example is given, and the enumeration approach and software simulation is proposed to get preventive maintenance cycle and cost under the different times of the preventive maintenance. The result shows that when equipment preventive maintenance cycle narrows gradually, maintenance cost decreases at first and increases later, and when the cost reaches the minimum, the availability reaches the maximum.",

        "abstract": "A novel ionic liquid consisting of a PEG-functionalized ammonium cation and a lacunary-type phosphotungstate anion was synthesized and characterized structurally. The ionic liquid was then immobilized onto environmentally benign polymer-carboxymethyl cellulose by two different routes: the impregnation method and the co-precipitation method. The immobilized ionic liquid can be used as a catalyst for olefin epoxidation with aqueous hydrogen peroxide in ethyl acetate. It was found that both of the immobilized ionic liquid catalysts showed better catalytic activities and stability than the homogeneous analogue in consecutive runs. In particular, the ionic liquid catalyst immobilized by the co-precipitation method afforded a higher catalytic stability than the catalyst immobilized by the impregnation method. It is suggested that the crucial factor influencing the catalytic performance is the difference in the interactions between the heteropoly anions and the polymer supports. \u00a9 2014 the Partner Organisations.",

Niobium peroxides modified with ionic liquid-type 1-dodecyl- 3-methylimidazolium hydroxide or conventional tetradecyl trimethyl ammonium hydroxide surfactants demonstrated excellent yields (80-99%) for the epoxidation of allylic alcohols to their epoxides even if the reaction was performed without any other solvent at 0\u00b0C for 0.5 h. The catalyst characterization demonstrated that the surfactant molecules were anchored on the surface of the niobium catalyst by weak noncovalent interactions. Compared with niobium peroxides, the modified amphiphilic catalysts allowed easier accessibility to hydrophobic substrates and thus demonstrated high reaction rate and excellent recyclability for the epoxidation under mild conditions.",

Through the present reaction route, not only can the urea derivatives be obtained in high yield, but also inorganic salt ammonium bicarbonate (ABic) can be successfully isolated simultaneously from the reaction mixture. The phase behavior observed in situ by high pressure visual autoclave illustrated that the reaction occurred in biphasic conditions during the reaction. A number of verifying tests were conducted to investigate the role of carbon dioxide and water in the system. It was found that reaction temperature, total pressure, reaction time, and water played a crucial role in producing urea derivatives. The further investigation showed that the transamidation reaction between various amines and urea occurred successfully without the addition of any other catalysts in the presence of CO",

        "abstract": "Aim: To assess the effect of acupuncture on anxiety-related behaviors after heroin-withdrawal, and explore its possible mechanism. Methods: Heroin was injected subcutaneously according to the principle of daily increasing dose in rats of experimented group. The abstinence signs were precipitated by naloxone after drugs were stopped. and the animal model of heroin addiction was established. Acupuncture was continuously given for 7 days. The elevated plus maze test was used to observe anxiety level after heroin-withdrawal and the anti-anxiety effect of acupuncture. The concentration of corticosterone (CORT), adrenocorticotropic hormone (ACTH) and arginine vasopressin (AVP) in the plasma of the rats were detected by radio-immunity. Expressions of Fos protein in the paraventricular nucleus of rat hypothalamus were detected by immunohistochemistry method. Results: Acupuncture significantly increased the percentage of entries into open arms and time spent on open arms (P <0.01 or P <0.05). The radioimmunoassay results showed that acupuncture decreased plasma CORT, ACTH and AVP in heroin-withdrawal rats (P <0.01 or P <0.05). The immunohistochemistry results showed that the expression of Fos protein in hypothalamic paraventricular nucleus was decreased after acupuncture (P <0.01 or P <0.05). Conclusions: Acupuncture reduces anxiety level of heroin-withdrawal rats and modulates the hypothalamic-pituitary-adrenal system activities. These findings suggest that acupuncture at \"shenmen\" point may be useful as a therapeutic treatment in heroin withdrawal induced emotional disorders. and its mechanism may be related to modulating the activities of hypothalamic-pituitary-adrenal system.",

        "abstract": "Objective: To study the mental health and personality of psychological commissioners and provide the timely help and pertinence training the healthy psychology and good personality in order to make them competent for the job and develop it smoothly in the future. Methods: 4531 persons which are included 337 psychological commissioners in grade 2010 freshmen were investigated by using Symptom Checklist 90 (SCL-90). 3540 freshmen which are included 240 psychological commissioners were investigated by using Eysenck Personality Questionnaire (EPQ). Results: In SCL-90, the total score and different factors values of those psychological commissioners were markedly lower than the other freshmen. In addition to somatization, hostility, the contrasts of the other scores are statistical (P<0.05). In EPQ, In E items, the score the psychological commissioners got is higher than the other freshmen. While in L item, the score is lower (P<0.01). As those psychological commissioners' mental health, only the contrast of phobic anxiety is statistical between male and female (P<0.01). To the students of different majors, those scores have no obvious differences (P>0.05). In EPQ , As those psychological commissioners' personality, the score in P item that the female got is lower than that the male got, while in E N L items, the scores are higher than those the male got. Score in L is statistical (P<0.01). Those scores in P E N L have no obvious differences in different majors (P>0.05). Conclusions: The psychological commissioners' mental healthy level is obviously better than other students. The personality characteristics of the psychological commissioners are suitable for the mental health education. There is no big difference of mental health and personality characteristics of psychological commissioners among different group members. All these results remind us that the choosing standard is very important when we choose the psychological commissioners. Furthermore, we should strengthen the psychological commissioners training. \u00a9 2012 Springer-Verlag GmbH Berlin Heidelberg.",

        "abstract": "OBJECTIVE: To investigate the clinicopathological features of soft tissue chondromas(STCs) and their histogenesis. METHODS: Eleven STCs were analyzed by the clinical manifestations, imaging features, histopathological characteristics and immunohistochemical phenotypes. RESULTS: Clinically, the presenting symptom was usually a slowly and insidiously growing mass. Imagings usually revealed a lobulated soft tissue mass partly with calcifications of variable density and showed not any relationship to the adjacent bone. Histologically, all of the tumors composed of mature hyaline cartilage or fibrocartilage were well circumscribed and lobulated with partly or completely calcified, focal myxoid and cystic changes. The appearance of the most chondrocytes were varied from dysplastic spindle-shaped to mature chondrocytes without noticeable cytologic atypia and mitotic figures. The spindle cells arround some of the cartilage lobules were without any lacuna or peri-cell halo. Immunohistochemistry was diffusely positive for vimentin in all tissues and the mature hyaline cartilage cells and spindle-shaped chondrocytes were also variedly positive for S-100 and for CD34. The mesenchymal spindle cells arround the cartilage lobules were partly positive for a-SMA, MSA and CD34, scatteredly for CD163. The mature hyaline cartilage matrix stained variedly for Collagen II and negative or focally for Collagen I and Collagen III; The fibrocartilage matrix including calcified region were strongerly positive for Collagen I and Collagen III, negative or focally for Collagen II. CONCLUSIONS: STCs are relatively rare benign cartilaginous tumors of soft parts more probably origined from the CD34-positive mesenchymal spindle cells. This pathogenesis of STCs based on some immunohistochemical phenotypes should be explored deeply.",

Its objective is oriented to plot the 1:50000 and 1:25000 topographic maps. Comparing with foreign commercial mapping satellite imagery, the establishment of our own imaging geometry model is the core technical problem for different products and various applications of ZY-3 surveying satellite. This paper analyses the key problem on precision geometry processing based on the overall design, and proposes the ZY-3 surveying satellite imaging geometry model with the technology of virtual CCD line-array imaging. In addition, this paper utilizes the first orbit imagery of ZY-3 satellite with coverage of the region of Dalian, and produces forward, backward and nadir cameras calibration products. Different ground control points are selected for the block adjustment experiment, and the digital surface model (DSM), digital ortho map (DOM) are generated. The accuracy is validated by check points. It can be seen from the experiment that the planar and vertical accuracy are better than 3 meters and 2 meters, respectively. The experiment demonstrates the effectiveness of ZY-3 surveying satellite imaging geometry model.",

        "abstract": "Peroxisome proliferator-activated receptor (PPAR) \u03b3 is a nuclear receptor involved in the regulation of lipid metabolism. In the present study, we sought to investigate the effects of emodin, an anthraquinone derivative isolated from the roots of Rheum palmatum, on PPAR\u03b3 signalling and cholesterol efflux in macrophage foam cells. Oxidized low-density lipoprotein (oxLDL)-stimulated THP1 macrophages were incubated with different concentrations of emodin (0-10\u00a0\u03bcmol/L) for 18\u00a0h. Western blot analysis and semiquantitative reverse transcription-polymerase chain reaction were used to assess the expression of key genes involved in cholesterol efflux, namely PPAR\u03b3, liver X receptor (LXR) \u03b1, ATP-binding cassette transporter (ABC) A1 and ABCG1. In addition, apolipoprotein (apo) A-I-mediated cholesterol efflux in emodin-treated cells was measured. Expresssion of PPAR\u03b3 mRNA and protein was increased in emodin-treated cells in a time- and dose-dependent manner. Emodin treatment also concentration-dependently induced LXR\u03b1, ABCA1 and ABCG1 expression. Moreover, emodin promoted apoA-I-mediated cholesterol efflux from oxLDL-loaded THP1 macrophages, which was significantly abolished by pretreatment with the PPAR\u03b3-selective antagonist GW9662 or the specific small interfering RNA for PPAR\u03b3. Together, the results demonstrate that emodin promotes cholesterol efflux from THP1 macrophages via activation of the PPAR\u03b3 signalling pathway and may represent a potential anti-atherosclerotic drug.",

The aim of the current study was to explore a potential correlation between a polymorphism in the miR-143 promoter region, rs4705342, and essential hypertension (EH). Genotyping for miR-143 rs4705342 was performed from blood samples of 156 EH patients (case group) and 187 healthy individuals (control group) using a TaqMan assay. Participant demographic and clinical characteristics were also collected. Logistic regression was used to identify an association between genotype and EH, and odds ratios of EH risk were also determined. Frequencies of the CC, CT, and TT genotypes differed significantly between case (7.7%, 40.4%, 51.9%) and control (15.0%, 48.1%, 36.9%) groups (\u03c7",

Methods: a total of 42 patients, who suffer from simple obesity but are complicated with mild to moderate hypertension, are selected and then randomly divided into an observation group and a control group by the digital table method. Each group consists of 21 patients. The patients in the control group are treated by the normal oral drugs, while those in the observation group are intervened by acupoint massage except the normal oral drug treatment provided for the control group. Respectively test the body fat percentage content, blood fat and blood pressure indicators of the selected patients in the two groups before treatment and after 12 weeks\u2019 treatment. Results: after 12 weeks\u2019 treatment, systolic blood pressure, diastolic blood pressure and blood fat indicators of the patients in the control group are improved significantly compared with those before treatment, P < 0.05, but their percentage of body fat does not change significantly, P > 0.05; systolic blood pressure, diastolic blood pressure, blood fat and body fat percentage of the patients in the observation group are significantly improved compared with those before treatment and their improvement effect is better than that of the control group, P < 0.05. Moreover, the relapse rate of the patients in the observation group, who have been cured, is also obviously lower than that of the control group. Conclusion: as for the simple obesity patients who are complicated with hypertension, if they accept acupoint massage stimulation therapy, assisted with oral drugs for treatment, their curative effect is obviously superior to that of the single drug treatment.",

From the angle of the impact of forecast error on power system or the acceptable forecast error of wind power system, this paper analyzes the prediction results of wind farms power, proposes the pre-evaluation concept of forecasting electrical outputs from wind farms, and provides the criterion and principle of pre-evaluation. Based on this, in order to meet the requirements of wind farm prediction for the time scale and precision scale in economical dispatch of wind power system, the pre-evaluation standard of wind farm short-term forecast is proposed and the criterion model of pre-evaluation is established. Taking an IEEE 30 bus six-generator system as a simulation example, based on the strategy of maximum active power output of wind farm, the pre-evaluation criterion of wind power short-term forecast is simulated, and the results show that the proposed pre-evaluation concept can promote scientific evaluation of wind farm active power output and acquisition of forecast results, as well as improve economical dispatch level in integrating wind generators into power system.",

To determine the phylogenetic position of S. crocodilurus with related species within Squamata, the phylogenetic tree was reconstructed with the concatenated nucleotide sequences of the 12 heavy-strand-encoded protein genes. Phylogenetic analyses based on maximum parsimony and Bayesian inference methods consistently support that the S. crocodilurus was closely related to the Helodermatidae within a monophyletic Anguimorpha group. And the result here contradicted the monophyly of Varanoidea (Varanidae Helodermatidae). In addition, the Gekkonidae was found to possess a basal phylogenetic position within squamata and the traditional hypothesis of monophyletic lineages of Iguania and Scleroglossa was not supported in this study. \u00a9 2012 Informa UK, Ltd.",

Several clinical trials had investigated imatinib mesylate with a target dose of 400-600 mg/day on SSc, and the efficacy is controversial with a generally poor tolerability. We herein reported six female Chinese patients with SSc administered with lowdose imatinib (200 mg/day) for a median of 23 months (10-30 months). Patients displayed a decreased modified Rodman skin scores (mRSS) by a mean of 6.29 points after 6 months of treatment. Three patients who completed 2 years of treatment achieved a reduction of mRSS by 8, 18, and 30.5 points, respectively. Pulmonary function was improved or stabilized in two patients with interstitial lung disease. Severe gastrointestinal involvement in one patient was attenuated in terms of discontinuation of total parenteral nutrition and restoration of the serum albumin level. Imatinib was welltolerated in general, although there were two severe adverse events: a bone fracture and a cerebral hemorrhage in two individuals. Both the adverse events were probably not directly related to imatinib and were recovered uneventfully. Our limited data, along with the review of the literature, suggested that low-dose imatinib might be effective and better tolerated in severe SSc that deserves further study. \u00a9 Clinical Rheumatology 2012.",

        "abstract": "Objective: Pulmonary arterial hypertension (PAH) is a severe complication of systemic lupus erythematosus (SLE) and could be an acute critical condition presenting to the emergency department (ED). Our previous retrospective study revealed that the ED-related mortality of such patients was over 50%. The aim of the current prospective study is to initiate a proactive intense care strategy on severe SLE-PAH patients in the emergency setting and evaluate its impact on the short-term survival. Methods: The proactive intense care strategy was applied, which includes: (i) an education and training course on the topic of SLE-PAH for ED physicians; (ii) a SLE-PAH patient triage protocol with prompt specialist consultation and admission; and (iii) intensive care with prompt initiation of combination PAH-targeted therapy, that is, at least two drugs from the three categories as represented by iloprost, bosentan and sildenafil. Consecutive SLE-PAH patients with WHO functional class III or IV who attended the ED were enrolled following the aforementioned protocol. A historical group of SLE-PAH patients in the ED (n = 11) was set up as a comparison, and 3-month short-term survival was calculated. Results: During October 2010 to December 2012, a total of 11 consecutive severe SLE-PAH patients were included in the present study. Compared with the historical group, an improved short-term survival can be appreciated over time (historical group vs. proactive group, 27.3% vs. 72.7%, P = 0.033). The application of PAH-targeted combination therapy apparently contributed to the better outcome (P = 0.0099). Conclusions: Proactive care and combination PAH-targeted treatment can improve short-term survival of severe SLE-PAH in the emergency setting.",

        "abstract": "Objective To investigate the role of autoantibodies against endothelin 1 receptor type A (ETRA) in patients with systemic lupus erythematosus (SLE)-associated pulmonary arterial hypertension (PAH) and to examine the possibility that the pathogenesis of this disease is mediated by these autoantibodies. Methods ETRA autoantibodies in serum from patients with SLE-associated PAH and serum from controls (SLE patients without PAH) were detected via a human ETRA epitope peptide-based enzyme-linked immunosorbent assay. An exploratory cohort of patients with SLE-associated PAH (n = 76) and an independent validation cohort of patients with SLE-associated PAH confirmed by right-sided heart catheterization (RHC) (n = 82) were enrolled. The clinical relevance of ETRA autoantibodies in SLE-associated PAH was analyzed. The proliferation of vascular smooth muscle cells (SMCs) and the permeability of endothelial cells (ECs) were assessed in vitro in cells stimulated with polyclonal ETRA IgG autoantibodies. Expression of PAH-related markers, i.e., serotonin transporter, platelet-derived growth factor receptor \u03b2, vascular endothelial growth factor A, and platelet-derived growth factor B was measured by quantitative polymerase chain reaction. In addition, a suboptimal dose of monocrotaline was used to induce PAH in rats, and the effect of ETRA autoantibodies in vivo was determined using a right ventricular hypertrophy index, pulmonary angiography, and laboratory parameters. Results ETRA autoantibodies occurred more frequently in SLE-associated PAH (41.5%) than in controls (17.1%). There was a significant correlation between ETRA autoantibody titers and pulmonary artery systolic pressure measured by echocardiography (r = 0.2978, P = 0.0038) or pulmonary artery systolic pressure measured by RHC (r = 0.2159, P = 0.0257) in SLE-associated PAH. ETRA autoantibodies could promote SMC proliferation, disrupt the endothelial barrier, and up-regulate expression of PAH-related markers, which could be blocked in the presence of an endothelin receptor antagonist. ETRA autoantibodies aggravated right ventricular hypertrophy and vascular remodeling in vivo. Conclusion We identified ETRA autoantibodies as a biomarker of mechanistic relevance in SLE. These autoantibodies may mediate PAH development in SLE.",

        "abstract": "Abstract Direct production of useful fuel from the emitted carbon dioxide has been one of major challenges in industries. We here report a novel approach in which ethanol could simply be synthesized under negative DC corona discharge at 1 atm and 105 \u00b0C. The experimental results have shown that CO<inf>2</inf> and H<inf>2</inf>O could be reduced mainly into ethanol with yield of 4.7% without applying any metal catalyst. And with increase of total feeding pressure of gases, the yield appears to rise. The mechanism of electron attachment on those gaseous molecules creating accelerated anions might be the key of CO<inf>2</inf> and H<inf>2</inf>O reduction reaction. This finding also implies that it might be feasible to use of negative corona discharge and CO<inf>2</inf> as only carbon source with steam as only source of hydrogen to produce energy-dense ethanol fuel, also possibly leading to electric energy storage.",

        "abstract": "The mechanism for nuclear envelope (NE) assembly is not fully understood. Importin-\u03b2 and the small GTPase Ran have been implicated in the spatial regulation of NE assembly process. Here we report that chromatin-bound NLS (nuclear localization sequence) proteins provide docking sites for the NE precursor membrane vesicles and nucleoporins via importin-\u03b1 and -\u03b2 during NE assembly in Xenopus egg extracts. We show that along with the fast recruitment of the abundant NLS proteins such as nucleoplasmin and histones to the demembranated sperm chromatin in the extracts, importin-\u03b1 binds the chromatin NLS proteins rapidly. Meanwhile, importin-\u03b2 binds cytoplasmic NE precursor membrane vesicles and nucleoporins. Through interacting with importin-\u03b1 on the chromatin NLS proteins, importin-\u03b2 targets the membrane vesicles and nucleoporins to the chromatin surface. Once encountering Ran-GTP on the chromatin generated by RCC1, importin-\u03b2 preferentially binds Ran-GTP and releases the membrane vesicles and nucleoporins for NE assembly. NE assembly is disrupted by blocking the interaction between importin-\u03b1 and NLS proteins with excess soluble NLS proteins or by depletion of importin-\u03b2 from the extract. Our findings reveal a novel molecular mechanism for NE assembly in Xenopus egg extracts. \u00a9 2012 IBCB, SIBS, CAS All rights reserved.",

        "abstract": "Objective: To understand the endemic situation dynamics of schistosomiasis in domestic animals (mainly bovine) in mountainous endemic regions, so as to provide the reference for evaluating the control effect and improving control strategy. Methods: Two representative pilots (Renmei and Dacang) in mountainous schistosomiasis endemic regions were selected for survey. The schistosome infection status of bovine was investigated by the miracidium hatching method, the pasture of bovine were investigated by home visiting, and the distributions of wild feces and Oncomelania snails, and the snail schistosome infection status were also investigated in April and September every year. Results: The schistosome infection rates of bovine reduced by 98.4% and 93.8% in two pilots in 2007 compared with those in 1993, and the infection intensities also showed a decline trend. The infection rate of wild faces was 0 in Renmei pilot since 1995, while in Dacang pilot, the infection rate of wild feces fluctuated in 2007, and the intensities of living snails and infected snails showed a declined trend. Conclusions: Due to the special natural environment of mountainous endemic regions, there is a dot-like or band-like distribution of endemic areas. The strengthening of schistosomiasis examination and chemotherapy will rapidly reduce endemic situation. However, to completely interrupt the transmission of schistosomiasis, we should emphasize environmental modification and domestic animal management.",

With numerical simulation and experiment, the relation between the coil geometry parameters and inductance change of planar inductor coil is analyzed. The result indicates that when the ferrous metal particles go through the detection channel, the measured inductance change increases with the number of coil turns and decreases with the coil line width.

Compound 7p (7-heptyloxy-4,5-dihydro-imidazo[1,2-a]quinoline) was found to be the most potent inhibitor. The minimum inhibitory concentration (MIC) of compound 7p against Escherichia coli was 0.5 \u03bcg/mL, better than that of reference agent ciprofloxacin and amoxicillin.

        "abstract": "BACKGROUND: Studies have shown that small-particle embolic agents can easily perform embolization by micro-catheter, and the arterioles can be embolized well by 50-100 \u03bcm particles to reduce collateral circulation generation. OBJECTIVE: To observe the pathological changes following embolizing rabbit pulmonary microcirculation with self-made embolic agents. METHODS: Self-made Fe<inf>3</inf>O<inf>4</inf> fine particles with a size of 50, 100, 150, 200, 250 \u03bcm and self-made gelatin sponge with a diameter of 500-1 000 \u03bcm were employed for interventional embolism of the pulmonary artery from New Zealand white rabbits. Then, the embolic effect was observed. RESULTS AND CONCLUSION: Angiography and pathological results showed that 50, 150, 250 \u03bcm Fe<inf>3</inf>O<inf>4</inf> fine particles and gelatin sponge particle could embolize to different-diameter microcirculatory blood vessels. Fe<inf>3</inf>O<inf>4</inf> fine particles could result in the embolization of rabbit capillaries and precapillary arterioles until 1-4 weeks after interventional embolism, indicating that Fe<inf>3</inf>O<inf>4</inf> fine particle had a long-time embolism effect. Fe<inf>3</inf>O<inf>4</inf> fine particles could also pass though the microtubule, and no ectopic embolization was visible. Gelatin sponge particles that were unable to pass through the microtubule could block the small arteries with a diameter of (1 300\u00b1348) \u03bcm. Gelatin sponge particles could be absorbed within 1-2 weeks after embolization. These findings suggest that Fe<inf>3</inf>O<inf>4</inf> particles have good embolic effect that is persistent and complete, and it is difficult to vascular recanalization and establishment of collateral circulation after embolization. Gelatin sponge as an embolic agent is suitable for branches and small arteries rather than the microcirculation.",

However, little is known about the role of HIF-1\u03b1/ IGF-I in VEGF expression in patients with diabetic vascular complications. The aim of this study was to elucidate the associations between HIF-1\u03b1, IGF-I, and VEGF in type 2 diabetes mellitus (T2DM) patients with or without vascular complications. Methods: Sixty patients with T2DM, with(A), and without vascular disease (B) and 26 controls were enrolled. Clinical parameters, HIF-1\u03b1, IGF-I and VEGF were assessed in the study and associations among them were analyzed by Spearman rank correlation. Results: Serum levels of VEGF, HIF-1\u03b1 and IGF-I were significantly higher in the diabetic patients than in the controls. Positive correlations existed between VEGF and HIF-1\u03b1 and between HIF-1\u03b1 and IL-6 in both groups A and B and in the control group. Conclusions: Our data demonstrate that HIF-1\u03b1 and IL-6 could regulate VEGF expression, and that higher levels of HIF-1\u03b1, IL-6, and VEGF may contribute to the pathogenesis of diabetic micro-angiopathy. \u00a9 2013 by the Association of Clinical Scientists, Inc.",

        "title": "Regulation of hepcidin through GDF-15 in cancer-related anemia",
        "abstract": "Background: High prevalence and unresponsiveness to erythropoiesis-stimulating agents are 2 major limitations to the treatment of cancer-related anemia (CRA). They are often related to the dis-regulation of iron metabolism regulated by hepcidin, but the regulatory pathway of hepcidin in CRA is poorly understood. Enhanced GDF-15 levels contribute to the cancer progression and metastasis, and also have been found to suppress hepcidin expression in anemia characterized by ineffective erythropoiesis. The pathophysiological mechanisms and the relationship of GDF-15 and hepcidin in CRA remain to be elucidated. Methods: The concentrations of hepcidin and GDF-15 as well as the hematological and the iron parameters were determined in sera from 131 patients with cancer and 40 healthy controls. Results: Serum GDF-15 levels were increased significantly in patients with the severe CRA, compared with the mild or no CRA patients and the controls. Increasing GDF-15 levels corresponded to decreasing hepcidin concentrations. A trend toward a correlation between high levels of GDF-15 and poor prognosis of cancer was also found. Elevation of GDF-15 concentrations suppressed hepcidin expression at high concentrations. Conclusions: Our findings suggest that tumor progression results in increased GDF-15 secretion, which may down-regulate hepcidin expression, resulting in iron overload in cancer patients; this phenomenon has also been found in some patients with sideropenic anemia due to chronic blood loss.\u00a9 2013 Elsevier B.V.",

        "abstract": "Background: Vascular endothelial growth factor (VEGF) is involved in the pathogenesis of diabetic microvascular disease. Most diabetes patients have higher serum levels of ferritin that may participate in diabetic vascular complications through high oxidative stress induced by iron. However, the mechanistic link between ferritin and VEGF is obscure. The study investigated the association of VEGF and ferritin in patients with diabetic microvascular disease. Patients and Methods: Sixty patients with type 2 diabetes mellitus (T2DM) and 26 healthy individuals were selected in this study. Serum ferritin, VEGF, hematological parameters, and clinical data were assessed in this cohort. The Spearman rank method was used to evaluate the associations among them. Results: Serum levels of VEGF and ferritin were significantly higher in diabetes patients compared with the controls; levels of both were elevated with development of the disease. There were positive correlations between VEGF and glucose levels and between VEGF and ferritin in diabetes groups, especially in patients with diabetic retinopathy. Positive correlations were also found between VEGF level and the parameters of age, hemoglobin, and albumin in patients with diabetes hypertension. Conclusions: Our data suggest that high ferritin levels in T2DM are closely related to the development of diabetic vascular complications through interaction with VEGF. \u00a9 2014, Mary Ann Liebert, Inc.",

        "abstract": "The aim of this study was to investigate the distribution of Enterovirus 71 (EV71) receptors SCARB2 and PSGL-1 in human tissues. The samples were chosen from archived specimens, and the profiles of two receptors were detected in the gastrointestinal tract, lung, and brain in situ by immunohistochemistry. SCARB2 was detected in all the tissues studied, and strong staining was observed in the gastric fundus gland, mucosal and glandular epithelia of the intestine. Similar expression was found in bronchial epithelia and pneumocytes. In addition, SCARB2 was observed in the esophagus/gastric mucosal epithelia, neuron, glial cells, and blood vessels and the perivascular tissues of the brain. By comparison, PSGL-1 was expressed weakly in the mucosal and glandular epithelia of the small intestine and colon. PSGL-1 was expressed in a few bronchial epithelia, and weak staining was observed in the pneumocytes. However, PSGL-1 was found easily in the lamina propria of all the tissues studied, and strong staining of PSGL-1 was also observed in the neurons and glial cells. The distribution of the SCARB2 and PSGL-1 in human gastrointestinal tract, lung, and brain tissues correlated with the distribution of pathological changes seen in EV71 infection. The widespread prevalence of these receptors may help explain the multiple organ involvement in infection with EV71. \u00a9 2014 Elsevier B.V.",

Therefore, the combined utilization was the preferred process because of its higher efficiency and innocuous compared with single lime neutralization. The corresponding parameters were also evaluated to achieve the optimized arsenic removal efficiency.

The electronic properties and microstructure of the CIGS films with various annealing time were investigated. The various annealing time changes the content of the Cu-Se compounds. A high Cu-Se content leads to a high carrier concentration and a low mobility. An improved efficiency of the solar cell device was found to be highly correlated with the decrease of the Cu-Se content. By decreasing the Cu-Se content, a device with a highest efficiency of 8.63% was achieved in this work.",

The increase of the series resistance is usually considered to be able to improve the uniformity of solar cells, therefore, the effects of the series resistance are focused on. Based on the model of the solar cell, a large scale solar cell is regarded as a module comprised of several small scale solar cells in parallel. The computational results showed that the actual efficiency of the large scale solar cell is lower than the weighted averaged one. The increase of the series resistance can improve the uniformity of the module, but it cannot necessarily enhance the conversion efficiency. Only when the uniformity is good and the series resistance is small, can the increase of the series resistance enhance the conversion efficiency.",

The results show that a phase separation process occurs in the CIGS absorbers when the as-deposited CIGS samples are annealed at the temperatures between 210 and 380\u00b0C. The surfaces are partly covered by regular shaped grains and platelets, which are corresponding to Cu-Se phases. When the absorbers are annealed at the temperature higher than 410\u00b0C, the CIGS absorbers recrystallize. This process improves the grains size and makes the absorbers become homogeneous and compact. Hall analysis shows the variation of electronic properties with the increase of annealing temperatures. The relationships between the electronic properties and the microstructure have been discussed in the paper as well. The solar cells have been fabricated with an optimized annealing temperature of 550\u00b0C. The highest efficiency of the CIGS solar cell devices reaches 13.5%.",

This method deals the basic probability assignment by the entropy weight coefficient and grey incidence analysis, and solves the problem of related or conflicting evidences by improved D-S compound rules. A steel tube welded structure is utilized to validate this proposed method. Results show that the method presented in this paper is superior to the classical D-S fusion theory.

        "abstract": "Objective: To assess the efficacy and safety of oxiracetam in the treatment of patients with post-stroke cognitive impairment. Methods: In this randomized, double-blind trial, 200 patients with post-stroke cognitive impairment were randomized 1:1 to receive; oxiracetam 800 mg and 4 piracetam simulation tablets three times daily for 6 months, or piracetam 1600 mg and 2 oxiracetam simulation capsules, three times daily for 6 months. These clinical parameters were tested by Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE) and Activity of Daily Living Scale (ADL) during a 6-month follow-up period. Results: After 6 months of treatment, the MMSE score showed that the oxiracetam-intervention group's score improved by a mean of 3.24 points, with a total effective rate of 91.6%, which was higher than that of the control group(2.30 points), and the difference in point change between the 2 groups was statistically significant (t = 2.079, P = 0.039), MoCA score showed that the oxiracetam-intervention group's score improved by a mean of 5.82 points, which was higher than that of the control group (4.76 points). The ADL efficacy analysis showed that the oxiracetam-intervention group's score decreased by a mean of 6. 44 points, which was higher than that of the control group (4.39 points), and the score ratio change differences between the 2 groups was not statistically significant (t = 1.798, P = 0.074; t = -1.914, P = 0.057). The situation of patients' cognitive impairment got better along with the oxiracetam treatment for 1, 2, 4, 6 months, so was the total effective rate (P<0.01). Conclusions: This research proves that oxiracetam has definitely therapeutic effect on patient with post-stroke cognitive impairment. With the extension of treatment time, the situation of patients gets even better. MMSE score shows that oxiracetam has better effect on improving post-stroke cognitive impairment than piracetam, and oxiracetam does not show any serious adverse reactions. Oxiracetam has little adverse reactions and it shows impressive safety. Copyright \u00a9 2013 by the Chinese Medical Association.",

The vast majority were classified as G1 genotype (n=82), and two samples from human patients in Sichuan province were identified as G3 genotype. Based on the concatenated sequences of nad1+atp6, 28 different haplotypes (NA1-NA28) were identified. A parsimonious network of the concatenated sequence haplotypes showed star-like features in the overall population, with NA1 as the major haplotype in the population networks. By AMOVA it was shown that variation of E. granulosus within the overall population was the main pattern of the total genetic variability. Neutrality indexes of the concatenated sequence (nad1+atp6) were computed by Tajima's D and Fu's Fs tests and showed high negative values for E. granulosus, indicating significant deviations from neutrality.

In this study, we assessed genetic variability and genetic structure of E. granulosus in the Tibet plateau, using the complete mitochondrial 16S ribosomal RNA gene for the first time. We collected and sequenced 62 isolates of E. granulosus from 3 populations in the Tibet plateau. A BLAST analysis indicated that 61 isolates belonged to E. granulosus sensu stricto (genotypes G1-G3), while one isolate belonged to E. canadensis (genotype G6). We detected 16 haplotypes with a haplotype network revealing a star-like expansion, with the most common haplotype occupying the center of the network. Haplotype diversity and nucleotide diversity were low, while negative values were observed for Tajima's D and Fu's Fs. AMOVA results and Fst values revealed that the three geographic populations were not genetically differentiated. Our results suggest that a population bottleneck or population expansion has occurred in the past, and that this explains the low genetic variability of E. granulosus in the Tibet Plateau.",

        "abstract": "Background: The previous studies have shown that electroporation-mediated recombinant plasmid pIRES-hBMP2-hVEGF165 can promote the early angiogenesis and new bone formation in the traction zone. Objective: To investigate the effect of gene transfection at different time on the new bone formation in the traction zone during mandibular distraction in rabbits, so as to explore the optimal time for gene therapy and obtain a better treatment effect. Methods: Forty-eight New-Zealand rabbits were employed. After accomplished the bilateral mandibular osteotomy and distractor implantation under general anaesthesia, the rabbits were randomly divided into four groups. The bilateral traction zones were transfected with the 2 \u03bcg (0.1g/L) recombinant plasmids pIRES-hBMP2-hVEGF165 at latency period, traction period and consolidation period, respectively, and the rabbits in these three groups received electroporation stimulation. The simple traction group only received traction without gene transfection. The rabbits in each group received traction at 3 days after modeling with the rate of 0.8 mm/d and once per day, and continuous traction for 10 days; three rabbits were sacrificed in each group at 1, 2, 4 and 8 week. The new tissues in the mandibular traction zone were cut for histological observation and histomorphometry analysis. Results and Conclusion: Histological examination and histomorphometry analysis showed that amounts of newly formed vessels, osteoblasts and mesenchymal cells of distraction period transfection group were greater than those of the latency period transfection group, consolidation period transfection group and simple traction group, and the new bone volume and the width of bone trabecula in the distraction period transfection group were higher than those in the other three groups (P < 0.05). It is better to transfect gene at the beginning of traction (distraction period) than at other stages of traction; in this way, we can obtain more remarkable effects on new bone formation. It suggests that the distraction stage is the optimal time for gene therapy.",

The Join and Leave Protocols provide backward and forward secrecy respectively. In this paper, we proposed a new anonymous group key agreement protocol based on ID-based encryption cryptosystems. The proposed protocol not only benefits from the desirable features of ID-based cryptosystem, but also provides privacy protection for users.

To systematically evaluate the effectiveness of the gonadotropin on apoptosis and proliferation of ovarian cells invivo, rats were injected subcutaneously with eCG and/or anti-eCG antiserum. Equine chorionic gonadotropin treatment increased ovarian cell proliferation and expression of FSH receptors (FSHR) as revealed by increased immunostaining of proliferating cell nuclear antigen and FSHR in rat ovary. These effects did not occur in a follicular stage-dependent manner. Moreover, these actions were abolished by anti-eCG antiserum. However, granulosa cells exhibited more intense Fas- and FasL-positive immunostaining during all follicular stages in the anti-eCG antiserum group. We used Western blot analysis to confirm these results; Fas and FasL protein contents in rat ovaries were decreased by eCG. Meanwhile, proliferating cell nuclear antigen and FSHR expression were upregulated by eCG. However, all these eCG-induced regulations were reversed by anti-eCG antiserum treatment. Furthermore, there were no significant differences between the anti-eCG antiserum and control groups. These results indicate that eCG promotes follicular development via downregulation of death-inducer Fas/FasL expression and promotion of ovarian cell proliferation, which is partially mediated by FSHR.",

        "abstract": "Controlled freezing-point storage means that the storage temperature is in a non-freezing temperature zone between the freezing point of water and food. It has been demonstrated that controlled freezing-point storage can prolong the storage-life of fresh food. Green beans (Phaseolus vulgaris L.) have been planted extensively in the northeast region of China and harvested seasonally. Degradation of cell wall polysaccharides has greatly affected the texture properties of the green bean cell walls. During controlled freezing-point storage, activities of cellulase, pectin methyl esterase, and polygalacturonase were inhibited effectively. It resulted in a slow degradation of cellulose and pectin, less expansion of the cell wall, and less dissolution of pectin layers. As a result, the web structure of the cell wall was preserved. At controlled freezing temperature, the hardness of green beans decreased slightly. Homogalacturonan of chelate pectin was degraded into galacturonic acid, and the side chains of the soluble alkali pectin were degraded into arabinose and galactose. At the later stage of controlled freezing-point storage, the web structure of the cell wall polysaccharides was destroyed. However, the pectin degradation in the green beans was inhibited significantly during controlled freezing-point storage.",

In the training stage, the Gaussian mixture model (GMM) of the Mel-frequency cepstral coefficients (MFCCs) of universal speaker is obtained. In speech enhancement stage, minima tracking process of IMCRA noise estimation is adjusted with the noisy power spectrum of current frame and an adjustment weighting factor. In addition, based on the universal GMM, some significant constant parameters are replaced by frequency-varying parameters, such as the weighting parameter in the DD priori SNR estimation and the adjustment weighting factor in the modified minima tracking process of IMCRA. The performance of proposed speech enhancement is evaluated by objective tests under various stationary and non-stationary noise environments. From experimental results, compared to the conventional approaches, the proposed scheme performs better and is suitable for being used as the pre-processing of speech processing systems.",

To improve the water solubility of this conjugated molecule, two carboxyl groups were introduced to chromophore OY-2 in the electron acceptor parts. Compared to the traditional D\u2013\u03c0\u2013A chromophores, chromophore OY-2 showed us great improvement in water solubility. The solubility of chromophore OY-2 in water could reach 300\u00a0ppm. Else, the thermal stability of chromophore OY-2 was also studied. Due to the presence of multi-carboxyl groups, the thermal stability of chromophore OY-2 was not very good. The initial decomposition temperature was just above 210\u00a0\u00b0C, which was attributed to the dehydration of the carboxyl groups. Though the SHG effect was not very high, it is large enough for the detection of SHG signal in water solution (0.2\u20130.3\u00a0pm/V).",

To clarify the effect of this exposure on lung inflammatory responses, 40 male Kunming mice were exposed in four similar static chambers, 0 (control) and three different doses of VOCs mixture (groups 1-3).

But, those evaluations were too rough. So in this study, we did more work to assess the anticonvulsant activity and the toxicity about BM- 1. The peak times of protection of BM-1 after intraperitoneal injection (ip) and oral administration (po) were determined using the MES test, and the anticonvulsant activity of it was compared with the reference drug, carbamazepine, at these peak times. The rotarod test was applied to measure its neurotoxicity.

        "abstract": "In this paper, We propose a effective method which joint transmit antenna selection (TAS) and artificial noise to promote communication security in MIMO wiretap channels. Firstly, based on TAS protocol, the transmitter selects one antenna (the max-antenna) that maximizes the instantaneous signal-noise-ratio (SNR) at the receiver. Secondly, the transmitter uses the max-antenna to transmit valid data, and simultaneously, uses the remaining antennas to transmit artificial noise which only affects the eavesdropper. Thirdly, The receiver and the eavesdropper employ maximal-ratio combining (MRC) to combine the received signals. We focus on the practical scenario where the transmitter does not have any channel state information (CSI) of the eavesdropper's channel. Our joint TAS and artificial noise scheme (TAS-AN) have low complexity, and can enhance the system's security. The numerical simulation results verify our analysis. \u00a9 (2014) Trans Tech Publications, Switzerland.",

        "abstract": "Our previous studies showed that pro-inflammatory cytokines (PIC) in the hypothalamic paraventricular nucleus (PVH) potentiated the cardiac sympathetic afferent reflex (CSAR) in normotensive rats. This study determined whether PIC in the PVH mediate enhanced CSAR and over-excited sympathetic activity in spontaneously hypertensive rats (SHR). CSAR was evaluated by renal sympathetic nerve activity (RSNA) response to epicardial application of bradykinin (BK). Inflammatory cytokine levels were measured with ELISA. In both SHR and normotensive Wistar-Kyoto (WKY) rats, PVH microinjection of PIC, tumour necrosis factor (TNF)-\u03b1 or interleukin (IL)-1\u03b2, increased the baseline mean arterial blood pressure (MAP), RSNA and the CSAR, but anti-inflammatory cytokines (AIC), IL-4 or IL-13, only increased the baseline MAP. PVH pretreatment with PIC caused sub-response dose of angiotension (Ang) II to produce baseline RSNA and MAP elevation and the CSAR enhancement responses, but AIC (IL-4 or IL-13) did not. PVH microinjection of PIC induced greater changes in SHR than in normotensive WKY rats. In addition, stimulation of cardiac sympathetic afferents with epicardial application of BK increased PIC levels in the PVH in both SHR and WKY rats. Intrapericardial administration of resiniferatoxin (RTX) which abolished the CSAR decreased the PIC levels in the PVH to a lower level in SHR than in WKY rats. These results suggest that the increased PIC in the PVH in SHR mediated the increased sympathetic outflow and the enhanced CSAR, and that the augmented effect of Ang II in the PVH on sympathetic activity and the CSAR is also associated with PIC. \u2022The PIC in the PVH increased the baseline RSNA, MAP and the CSAR in SHR.\u2022Changes caused by PIC were greater in SHR than in normotensive WKY rats.\u2022Synergetic effects of PIC with Ang II were greater in SHR.\u2022Stimulation of cardiac sympathetic afferents increased PIC levels in the PVH.\u2022Elimination of the CSAR decreased PIC to lower levels in SHR than in WKY rats.",

We surveyed thirty-two Chinese medical schools covering each geographic region of China at the Twelfth Medical Education Conference for China Mainland, Hong Kong, and Taiwan on a variety of topics related to the humanities and ethics. Thirty-one (96.9 percent) Chinese medical schools offer courses in the humanities, and all thirty-two (100.0 percent) Chinese medical schools surveyed offer courses on ethics. Of the thirty-one universities offering humanities courses, twenty-six (83.9 percent) have five or more humanities courses, and of the thirty-two universities offering ethics courses, twenty-six (81.3 percent) have five or more ethics courses. At ten (32.3 percent) universities, all humanities courses are compulsory, at one (3.2 percent) university, all humanities courses are elective, and eighteen (58.1 percent) universities have both compulsory and elective humanities courses. At eighteen (56.3 percent) universities, all medical ethics courses are compulsory, at one (3.1 percent) university all medical ethics courses are elective, and thirteen (40.6 percent) universities have both compulsory and elective medical ethics courses.

Although its use at medical schools in some Western countries has already been examined, no one has looked at its status in many other countries, including China. The aim of this study is to determine the number of schools currently using PBL in China, the degree to which they use it, and the reasoning behind such usage. Methods: We used survey and internet search to examine PBL usage at Chinese medical schools. We were able to collect data from 43 first-class Chinese medical schools that are geographically diverse and thus representative of medical schools all across China. Results: 34 (79.1%) of the 43 medical schools use PBL in the preclinical curriculum. Of the 34, data were collected from 24 (70.6%) medical schools regarding the extent of their PBL usage. Nine (37.5%) schools use PBL for less than 10% of preclinical hours, 14 (58.3%) schools use PBL for 10-50% of preclinical hours, and one (4.2%) school uses PBL for more than 50% of preclinical hours. Conclusion: In our sample of Chinese medical institutions, a large majority of schools use PBL, however, most schools use it for less than 50% of total preclinical curricular hours. Our results suggest that schools are interested in increasing the number of curricular hours devoted to PBL but are constrained by resources. \u00a9 2014 Informa UK Ltd.",

        "title": "Improved droop control method for microgrid based on additional damping",
        "abstract": "When the traditional active power versus frequency and reactive power versus voltage magnitude droop control is applied, if the droop coefficients are irrational, the output power of the inverter will keep oscillating. When the microgrid operates in the islanding mode, the microgrid frequency will fluctuate because of the output power oscillation of the energy storage inverter. When serious, there will be the power angle stability problem. Based on the concept of dynamic frequency-power characteristic, this paper proposes an improved droop control method according to phase condition and magnitude condition of positive damping. The improved droop control can effectively increase system damping to suppress the oscillation of output power of the inverter and improve system stability without affecting the steady state frequency and output power of the inverter. Finally, PSCAD simulation results have validated the feasibility of the proposed method.",

        "title": "Chinese style VIEs: Continuing to sneak under smog?",
        "abstract": "The VIE (Variable Interest Entity) is a business structure that is comprised of a series of contractual arrangements that enable relevant parties to obtain a degree of control over, as well as a substantial economic interest in, certain companies without having to directly own their shares. For about fifteen years, by virtue of the VIE structure and its accounting treatment in the U.S. or Hong Kong, many China-based enterprises were successfully listed overseas, thus circumventing Chinese regulatory control on foreign equity ownership and investment restrictions in specific industries such as internet or education. In recent years, however, serious doubts arose about the validity and viability of the Chinese-styled VIE. Court judgments, arbitration awards, and administrative decisions from different sectors and levels have continued to pose challenges to the practice of creating Chinese-style VIEs. The egregious breach of contracts and the chaotic battles over control have also caused foreign investors to suffer, eliciting concern from the SEC and HKEx. This Article reviews the structure, origin, and logic of the VIE, and analyzes the evolution and dynamics of such practice. An argument can be made that China's best interests would be served by ending the murky situation surrounding the VIE; stopping this self-enforced vicious spiral by realigning the interests of the parties involved. One proposal suggests that a collective and coordinated regulatory framework that is characterized as less restrictive, more transparent, better defined, and more user friendly, should be set up for the VIE practice; this proposal should be initiated by the State Council and MOFCOM in particular. Moreover, international cooperation should be strengthened to better protect investors and deter opportunistic misbehavior.",

        "abstract": "This paper presents an integrated humidity sensor capable of wireless operation through inductive coupling. The sensor chip consists of two counter-rotating planar aluminum coils (0.5\u03bcm thick, 100\u03bcm width, 50\u03bcm space, 6mm outer diameter and 4 turns) separated by a maskless humidity-sensitive polyimide film. The two inductors are capacitively and inductively coupled together to form an inductor-capacitor (LC) electrical resonator, whose resonant frequency changes with humidity. In contrast with previous work, our proposed design eliminates the need of a connection bridge between the inner and outer terminals of the spiral inductor. Additionally, its inner humidity-sensitive overlap parallelplate capacitor offers higher sensitivity than the passive humidity sensor based on single-layer self-resonant inductor. An equivalent circuit model is investigated for further understanding of the electromagnetic behavior of the sensor. Measurements show a sensitivity of 65kHz/%RH with a centre frequency of about 74MHz.",

They represent some of the riskiest, most complex, and most uncertain projects to manage. As the foundation of project management, critical success factors (CSFs) have been emphasized by previous research. However, most studies identified and prioritized CSFs independently of stakeholders. This differs from the reality, where the success of green retrofits is tightly interrelated to the stakeholders of projects. To improve the analysis from a stakeholder perspective, the present study proposed an innovative method based on a two-mode social network analysis to integrate CSF analysis with stakeholders. The results of this method can provide further understanding of the interactions between stakeholders and CSFs, and the underlying relationship among CSFs through stakeholders. A pilot study was conducted to apply the proposed method and assess the CSFs for green retrofits in China. The five most significant CSFs are identified in the management of green retrofit. Furthermore, the interrelations between stakeholders and CSFs, coefficient and clusters of CSFs are likewise discussed.",

        "abstract": "Objective: To study the changes in serum cytokines levels in children with newly diagnosed active systemic juvenile idiopathic arthritis (SJIA) and to explore the role of cytokines in the development and progression of SJIA. Methods: Seventy-four pediatric patients with active SJIA between January 2010 and December 2013 were included in the study. Serum levels of interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukine-10 (IL-10), tumor necrosis factor (TNF), and interferon gamma (IFN-\u03b3) were measured by flow cytometry in these patients. The levels of cytokines were also determined in 202 healthy children as the control group. Routine laboratory parameters including white blood cell (WBC) count, percentage of neutrophils, hemoglobin level, platelet count, hypersensitive C-reactive protein (hs-CRP), and erythrocyte sedimentation rate (ESR) were monitored in the patient group. Results: The WBC count, percentage of neutrophils, hs-CRP, and ESR in 74 cases of SJIA were significantly above the normal range, their platelet counts were within the normal range, whereas hemoglobin levels were below the normal range. Compared with the control group, the patient group showed a significantly increased level of IL-6 (P<0.01) and significantly reduced levels of IL-4, IL-10, and TNF (P<0.01). However, there were no significant changes in serum levels of IL-2 and IFN-\u03b3 in the patient group (P>0.05). In SJIA children, IL-6 level, which was significantly elevated, was negatively correlated with hemoglobin level, which was significantly reduced (r=-0.244, P<0.05). Conclusions: Serum level of IL-6 is significantly increased in children with SJIA, and it has a negative correlation with anemia.",

        "abstract": "Objective: 25-Hydroxyvitamin D<inf>3</inf> [25(OH)D<inf>3</inf>] is the main product of vitamin D and can reflect the absolute concentration of active vitamin D in the body. This study examined serum 25(OH)D<inf>3</inf> levels in children with juvenile idiopathic arthritis (JIA) in order to explore the association of vitamin D concentrations with the pathogenesis and disease activity of JIA. Methods: Serum samples were collected from 53 children confirmed as having JIA between January 2013 and March 2014, as well as 106 healthy children (control group) who underwent physical examination in the same period. Serum concentrations of 25(OH)D<inf>3</inf> were measured using ELISA and compared between the cases and healthy controls. The association of serum 25(OH)D<inf>3</inf> levels with JIA subtypes, ACR Pediatric 30 Score, peripheral blood C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were analyzed in children with JIA. Results: Compared with the control group, the JIA group had significantly reduced serum 25(OH)D<inf>3</inf> levels (median: 42.6 nmol/L vs 49.9 nmol/L; P<0.01). The percentage of subjects with severe deficiency of vitamin D in the JIA group was significantly higher than that in the control group (17.0% vs 6.6%; P<0.05). Serum 25(OH)D<inf>3</inf> showed no significant correlations with JIA subtypes, ACR Pediatric 30 Score, CRP, and ESR in children with JIA. Conclusions: Vitamin D concentrations are significantly decreased in children with JIA. Decreased vitamin D concentrations may be associated with the pathogenesis of JIA. However, vitamin D concentrations may have no correlations with JIA subtypes, disease severity, and disease activity.",

        "abstract": "Background and objective The mechanisms of Mycoplasma pneumoniae induced lung inflammation are not clearly understood yet. This study investigated whether activated T cells in the airway contributed to the pulmonary inflammation in patients with severe Mycoplasma pneumoniae pneumonia (MPP). Methods BALF were collected in all 45 patients with MPP (MPP, n = 45), including mild (Mild, n = 20) and severe (Severe, n = 25) group. BALF in 20 of all 25 severe cases with MPP at the recovery stage (Rec-severe, n = 20) were collected again. The control group consisted of 20 patients with airway foreign body aspiration (Con., n = 20). CD3+ T cells, CD69+, HLA-DR+, CD25+ on CD3+ T cells in BALF were determined by flow cytometry. Levels of IL-6, IL-10 in BALF were determined by ELISA, and percentage of neutrophils was counted. Results A significant increased percentage of neutrophils and levels of IL-6 and IL-10, decreased percentage of CD3+ T cells, increased expressions of CD69+, HLA-DR+ or CD25+ on CD3+ T cells were observed in children with MPP compared with the control group (P < 0.05 or 0.01). Compared to mild group, the percentage of neutrophils, CD3+ CD25+, IL-6, and IL-10 were increased in children with severe MPP (P < 0.01 or 0.05). Compared to acute stage, an increased percentage of CD3+ T cells, decreased percentage of neutrophils and IL-6 level, and expressions of CD3+ CD69+ or CD3+ CD25+ were observed at the recovery stage in children with severe MPP (P < 0.01 or 0.05). Conclusions Increased activation of T cell in BALF may play an important role in the inflammatory response of acute and severe MPP. IL-6 may predict the severity and prognosis and provide a better assessment for patient care. However, the underlying mechanism awaits further detailed investigations.

        "abstract": "The solar radiation at different points within a solar greenhouse is not only an important parameter for the simulation of crop photosynthesis and transpiration, but also an essential factor for wall energy balance in a solar greenhouse. In this paper, the shadowing effect of a solar greenhouse enclosure structure on solar radiation was analyzed, and the preventing-view's angle of any points within a solar greenhouse was calculated by using the main parameters of a solar greenhouse and the solar azimuth. Any point could be obtained by direct solar radiation if the preventing-view's angle was smaller than the solar altitude. A hypothesis is that any point obtains isotropic diffuse solar radiation form the sky, diffuse solar radiation was calculated by accumulating the non- preventing-view's angle. Based on these analyses, the direct solar radiation, diffuse radiation, and the total solar radiation at any points within a solar greenhouse on sunny days were estimated. The estimated values at certain points within a solar greenhouse were compared with measured values at that point, which were measured within a LiaoshenII type solar greenhouse. The estimated values were higher than the measured values by 6.4% and 8.8% respectively for scatter radiation and total radiation, and the possible reasons that caused estimated errors were discussed. Results showed that the daily variation of estimated direct solar radiation, diffuse solar radiation, and total solar radiation tended to agree with that of the measured values, and the estimated values overestimated the measured values. The estimated errors maybe resulted from an error of the atmospheric transparency coefficient, transmittance of solar greenhouse plastic film, shadowing of load-bearing framework, and artificial observation errors. Using software surfer 8.0, a total radiation distribution map at 2 m was provided on 2011-12-24 at 10:00 within the greenhouse. At this height, the width was 7.05 m, and the length was 60 m. Total radiation had a decreasing trend from north to south. The shadow parts meant no direct radiation. The research results can supply theoretical solar radiation at different points within a solar greenhouse for the simulation of crop and transpiration, distribution of light within crop canopy, and energy balance of an enclosure structure in a solar greenhouse.",

These related miRNAs show similar evolutionary patterns and various expression patterns. Most of them show consistent isomiR expression pattern, and the \"switching\" phenomenon can be found between different abundant isomiR species. These findings suggest that these sequence or location related miRNAs show the similar miRNA processing and maturation processes, and the robust selection of the most dominant isomiR exists in specific tissues. Functional analysis show that these miRNAs show similar distributions of enriched gene categories, suggesting the close functional prelateships via direct or indirect coordinate regulation in biological processes. The study reveals the close evolutionary, expression and functional relationships between related homologous/clustered miRNAs, which will further enrich miRNA studies and understand direct or indirect interactions between miRNAs. \u00a9 2014 Liang et al.",

        "abstract": "Sequencing is widely used to discover associations between microRNAs (miRNAs) and diseases. However, the negative binomial distribution (NB) and high dimensionality of data obtained using sequencing can lead to low-power results and low reproducibility. Several statistical learning algorithms have been proposed to address sequencing data, and although evaluation of these methods is essential, such studies are relatively rare. The performance of seven feature selection (FS) algorithms, including baySeq, DESeq, edgeR, the rank sum test, lasso, particle swarm optimistic decision tree, and random forest (RF), was compared by simulation under different conditions based on the difference of the mean, the dispersion parameter of the NB, and the signal to noise ratio. Real data were used to evaluate the performance of RF, logistic regression, and support vector machine. Based on the simulation and real data, we discuss the behaviour of the FS and classification algorithms. The Apriori algorithm identified frequent item sets (mir-133a, mir-133b, mir-183, mir-937, and mir-96) from among the deregulated miRNAs of six datasets from The Cancer Genomics Atlas. Taking these findings altogether and considering computational memory requirements, we propose a strategy that combines edgeR and DESeq for large sample sizes.",

        "abstract": "Emerging evidence indicates that microRNAs (miRNAs), a class of small non-coding RNAs, are involved in a number of biological processes. The results of SOLiD\u2122 sequencing were used to analyze differentially expressed miRNA profiles in the plasma and placenta of patients with preeclampsia (PE) and a subject who had had a pregnancy without complications. miRNAs were identified that were consistently expressed in the placenta, following normalization of the raw data. miRNAs that had increased and differential expression were selected, as defined by percentage >0.02% and a log2 fold change \u2265|1.2|, respectively. This process was repeated in the plasma. Twenty such miRNAs were identified. These were: miR-126, miR-126\u2217, miR-130a, miR-135b, miR-142-3p, miR-149, miR-188-5p, miR-18a, miR-18b, miR-203, miR-205, miR-224, miR-27a, miR-29a, miR-301a, miR-517c, miR-518-3p, miR-518e, miR-519d and miR-93. These miRNAs belonged to 13 clusters or families. However, only four clusters or families involved two or more of these miRNAs. These were the mir-16 cluster, the mir-17 family, the mir-130 family and the mir-517 family. These abnormally-expressed miRNAs and miRNA gene clusters or families are known to be involved in a number of biological processes. Gene enrichment analysis was used to investigate the pathways involved in the development of PE. In conclusion, the miRNAs identified in this study as being abnormally expressed in PE, may be useful as non-invasive diagnostic biomarkers. Co-regulated mRNAs and possible causal pathways involved in the pathogenesis of PE were also identified.",

        "abstract": "Next generation sequencing technology has identified a series of miRNA variants (named \"isomiRs\"), which might be associated with cancer progression. We provide a new strategy to reanalyze the miR-seq datasets through a view of the isomiR spectrum. Firstly, differentially expressed (DE) isomiRs were detected with the DESeq algorithm based on negative binomial distribution. Secondly, the rank-based MANOVA was adopted to compare the isomiR patterns between normal and tumor tissues. Moreover, a comprehensive survey on classification performance of three features was conducted, including the logistic regression, k-nearest neighbors and Random Forest. Finally, functional enrichment analysis was performed with the putative targets of specific isomiRs to elucidate their biological functions. Furthermore, the methods were applied to the downloaded miR-seq datasets of breast invasive carcinoma from TCGA. We found that the expression levels of multiple isomiRs derived from the same miRNA locus showed significant inconsistency between normal and tumor samples. In most cases, logistic regression with multiple DE isomiRs was superior to the others, with highest AUC and lowest AIC. Similarly, DE isomiRs performed best in the average accuracy of standard classifiers. Integrated targets were significantly enriched in some cancer-related pathways, including MAPK signaling pathway, and focal adhesion. Collectively, we could recommend the rank-based MANOVA for comparing different isomiR patterns, and further investigation on isomiRs needs to be considered in miRNA sequencing research.",

        "abstract": "The observed decline of spring dust storms in Northeast Asia since the 1950s has been attributed to surface wind stilling. However, spring vegetation growth could also restrain dust storms through accumulating aboveground biomass and increasing surface roughness. To investigate the impacts of vegetation spring growth on dust storms, we examine the relationships between recorded spring dust storm outbreaks and satellite-derived vegetation green-up date in Inner Mongolia, Northern China from 1982 to 2008. We find a significant dampening effect of advanced vegetation growth on spring dust storms (r = 0.49, p = 0.01), with a one-day earlier green-up date corresponding to a decrease in annual spring dust storm outbreaks by 3%. Moreover, the higher correlation (r = 0.55, p < 0.01) between green-up date and dust storm outbreak ratio (the ratio of dust storm outbreaks to times of strong wind events) indicates that such effect is independent of changes in surface wind. Spatially, a negative correlation is detected between areas with advanced green-up dates and regional annual spring dust storms (r = -0.49, p = 0.01). This new insight is valuable for understanding dust storms dynamics under the changing climate. Our findings suggest that dust storms in Inner Mongolia will be further mitigated by the projected earlier vegetation green-up in the warming world.",

        "abstract": "Background and aims: Ground-penetrating radar (GPR) has provided a non-invasive means for field root investigation. However, the horizontal cross angle (x) of root orientation intersecting a survey line considerably impacts the amplitude area (A) reflected from a root and impairs the accuracy of GPR-based root quantification. Prediction of A(90\u00b0) (the value of A scanning at x = 90\u00b0) from multiple A(x) measurements could correct such impact. Previous method of A(90\u00b0) prediction focused on target roots at field point scale. The aim of this study is to develop a method to predict A(90\u00b0) at field plot scale. Methods: A(90\u00b0) was predicted by a pair of A(x) measured at two arbitrary scanning lines together with an estimated soil background amplitude area. Three independent datasets were employed to test the proposed method. The field experiment included radar data collected for six roots of Caragana microphylla in a sandy-clay soil at four cross angles (30\u00b0, 45\u00b0, 60\u00b0, and 90\u00b0). The sand box experiment included radar data for 12 dowels at 13 cross angles (0\u00b0 to 180\u00b0, in 15\u00b0 steps). The simulation experiment included A(x) of 46 simulated roots at 13 cross angles (0\u00b0 to 180\u00b0, in 15\u00b0 steps). Results: For all experiments, A(90\u00b0) was accurately estimated. Root orientation could also be determined. After correcting the impact of cross angle, the accuracy of root diameter estimation improved. Correlation coefficient between actual and estimated root diameters increased from 0.77 to 0.81, with RMSE declining from 9.53 to 7.05\u00a0mm. Conclusions: A method of correcting the influence of root orientation on root GPR signal at the field plot scale has been established. This method enhances root quantification using GPR.",

        "abstract": "Documenting the sex and sexual reproduction of the microalgae is very difficult, as most of the results are based on the microscopic observation that can be heavily influenced by genetic, physiological and environmental conditions. Understanding the reproduction strategy of some microalgae is required to breed them in large scale culture industry. Instead of direct observation of sex and sexual reproduction under microscope, the whole set or the majority of core meiosis genes may evidence the sex and sexual reproduction in the unicellular algae, as the meiosis is necessary for maintaining the genomic stability and the advantages of genetic recombination. So far, the available genome sequences and bioinformatic tools (in this study, homolog searching and phylogenetic analysis) allow us to propose that at least 20 core meiosis genes (among them \u22656 must be meiosis specific) are enough for an alga to maintain its sexual reproduction. According to this assumption and the genome sequences, it is possible that sexual reproduction was carried out by Micromonas pusilla and Cyanidioschyzon merolae, while asexual reproduction was adopted by Bigelowiella natans, Guillardia theta, Nannochloropsis gaditana, N. oceanica, Chlorella variablis, Phaeodactylum tricornutum and Thalassiosira pseudonana. This understanding will facilitate the breeding trials of some economic microalgae (e.g., N. gaditana, N. oceanica, C. variablis and P. tricornutum). However, the reproduction strategies of these microalgae need to be proved by further biological experiments.",

These findings indicate that the algal cells degrade its components (mainly amino acids and fatty acids) to yield excessive energy (ATP) to maintain cellular ion (mainly K<sup>+</sup> and Ca<sup>2+</sup>) homeostasis, while the depletion of amino acids and ATP, and the reduction of ribosomes attenuate the protein translation and finally slow down the cell growth.",

        "abstract": "Documenting the sex and sexual reproduction of the microalgae is very difficult, as most of the results are based on the microscopic observation that can be heavily influenced by genetic, physiological and environmental conditions. Understanding the reproduction strategy of some microalgae is required to breed them in large scale culture industry. Instead of direct observation of sex and sexual reproduction under microscope, the whole set or the majority of core meiosis genes may evidence the sex and sexual reproduction in the unicellular algae, as the meiosis is necessary for maintaining the genomic stability and the advantages of genetic recombination. So far, the available genome sequences and bioinformatic tools (in this study, homolog searching and phylogenetic analysis) allow us to propose that at least 20 core meiosis genes (among them \u22656 must be meiosis specific) are enough for an alga to maintain its sexual reproduction. According to this assumption and the genome sequences, it is possible that sexual reproduction was carried out by Micromonas pusilla and Cyanidioschyzon merolae, while asexual reproduction was adopted by Bigelowiella natans, Guillardia theta, Nannochloropsis gaditana, N. oceanica, Chlorella variablis, Phaeodactylum tricornutum and Thalassiosira pseudonana. This understanding will facilitate the breeding trials of some economic microalgae (e.g., N. gaditana, N. oceanica, C. variablis and P. tricornutum). However, the reproduction strategies of these microalgae need to be proved by further biological experiments.",

Protein silk fibroin (SF), which gained interest in biomaterial and regenerative medicine, was used in this study to stabilize gold (Au) NPs. Characterization results from UV-Vis spectroscopy revealed that SF-capped Au NPs (SF-Au NPs) possessed remarkable colloidal stabilities in the pH range of 2 to 11 and salt concentration range of 50 mM to 1000 mM. In addition, dried particle samples were resuspended after lyophilization without aggregation. The results indicated that the steric hindrance rather than the electrostatic repulsion of SF-Au NPs was essential for colloidal stability. The SF-Au NPs manifested improved cytocompatibility compared with bare Au NPs, which was attributed to the inherent non-cytotoxicity of SF and the good colloidal stability of the NPs. The proposed method was simpler, more efficient, and more cost effective than the conventional modification strategies for Au NPs; thus, SF-Au NPs can be potentially used in biomedical applications. \u00a9 2014 Elsevier B.V.",

        "abstract": "Thin films of nickel-aluminum-containing layered double hydroxide (NiAl-LDH) have been prepared on nickel foil and nickel foam substrates by secondary (seeded) growth of NiAl-LDH seed layer. The preparation procedure consists of deposition of LDH seeds from a colloidal suspension on the substrate by dip coating, followed by hydrothermal treatment of the nanocrystals to form the LDH film. The secondary grown film is found to provide a higher crystallinity and more uniform composition of metal cations in the film layer than the in situ grown film on seed-free substrate under identical hydrothermal conditions. A systematic investigation of the film evolution process reveals that the crystallite growth rate is relatively fast for the secondary grown film because of the presence of LDH nanocrystal seeds. Electrochemical performance of the resulting NiAl-LDH films as positive electrode material was further assessed as an example of their practical applications. The secondary grown film electrode delivers improved recharge-discharge capacity and cycling stability compared with that of the in situ grown film, which can be explained by the existence of a unique microstructure of the former. Our findings show an example for the effective fabrication of LDH film with controllable microstructure and enhanced application performance through a secondary (seeded) growth procedure.",

        "abstract": "Introduction: To investigate if decreased histone deacetylase 4 (HDAC4) is associated with human osteoarthritis (OA) cartilage degeneration by releasing HDAC4 inhibition of runt-related transcription factor-2 (Runx2) resulting in increase of OA cartilage degeneration-related genes. Methods: The mRNA and protein levels of HDAC4, Runx2, matrix metalloproteinase (MMP)-13, Indian hedgehog (Ihh) and type X collagen were detected by performing real-time PCR (RT-PCR), western blotting and immunohistochemistry on specimens from human OA and normal cartilage. To further explore the mechanism of regulation of Runx2 and OA-related genes by HDAC4, changes in these OA-related genes were further quantified by RT-PCR after overexpression of HDAC4 and knockdown of HDAC4 by siRNA. Runx2 and MMP-13 promoter activities were measured by dual luciferase assays. Results: The levels of HDAC4 in the cartilage from OA patients and healthy 40-to 60-year-old donors were decreased to 31% and 65% compared with specimens from 20-to 40-year-old healthy donors, respectively (P <0.05). Decreased HDAC4 was associated with increased Runx2 and other OA-related genes in human OA cartilage, specifically: MMP-13, Ihh and type X collagen. Exogenous HDAC4 decreased the mRNA levels of Runx2, MMP1, MMP3, MMP-13, type X collagen, Ihh, ADAMTS-4 and -5, and increased the mRNA of type II collagen. In addition, the data also shows that overexpression of HDAC4 not only decreased the expression of interleukin (IL)-1\u00df, Cox2 and iNos and increased the expression of aggrecan, but also partially blocked the effect of IL-1\u00df on expression of catabolic events in human OA chondrocytes. HDAC4 also inhibited Runx2 promoter activity and MMP13 promotor activity in a dose-dependent manner. In contrast, inhibition of HDAC4 by TSA drug had an opposite effect. Conclusions: Our study is the first to demonstrate that decreased HDAC4 contributes, at least in part, to the pathogenesis of OA cartilage degeneration. Thus, HDAC4 may have chondroprotective properties by inhibiting Runx2 and OA-related genes.",

        "abstract": "Video encoders and decoders for HEVC-like compression standards require huge external memory bandwidth, which occupies a significant portion of the codec power consumption. To reduce the memory bandwidth, this paper presents a new lossless reference frame recompression algorithm along with a high-throughput hardware architecture. Firstly, hybrid spatial-domain prediction is proposed to combine the merits of DPCM scanning and averaging. The prediction is then enhanced with multiple modes to accommodate various image characteristics. Finally, efficient residual regrouping based on semi-fixed-length (SFL) coding is used to improve the compression performance. Compared to no compression, the proposed scheme can reduce data traffic by an average of 57.6% with no image quality degradation. The average compression ratio is 2.49, an improvement of at least 12.2-13.2%, relative to the state-of-the-art algorithms. By applying a reordered two-step architecture and the two optimizations, residual reuse and simplified coding mode decision, the hardware cost is similar to that of previous reference frame recompression architectures. The computational complexity increase caused by multi-mode prediction affects the HW cost slightly. This work can be implemented with 45.1 k gates for the compressor and 34.5 k gates for the decompressor at 300 MHz, enough to support a 3840 x 2160@60fps video encoder and decoder.",

        "abstract": "Subsurface lateral preferential flow (LPF) has been observed to contribute substantially to hillslope and catchment runoff. However, the complex nature of LPF and the lack of an appropriate investigation method have hindered direct LPF observation in the field. Thus, the initiation, persistence, and dynamics of LPF networks remain poorly understood. This study explored the application of time-lapse ground-penetrating radar (GPR) together with an artificial infiltration to shed light on the nature of LPF and its dynamics in a hillslope. Based on our enhanced field experimental setup and carefully refined GPR data postprocessing algorithms, we developed a new protocol to reconstruct LPF networks with centimeter resolution. This is the first time that a detailed LPF network and its dynamics have been revealed noninvasively along a hillslope. Real-time soil water monitoring and field soil investigation confirmed the locations of LPF mapped by time-lapse GPR surveys. Our results indicated the following: (1) Increased spatial variations of radar signals after infiltration suggested heterogeneous soil water changes within the studied soil, which reflected the generation and dynamics of LPF; (2) Two types of LPF networks were identified, the network at the location of soil permeability contrasts and that formed via a series of connected preferential flow paths; and (3) The formation and distribution of LPF networks were influenced by antecedent soil water condition. Overall, this study demonstrates clearly that carefully designed time-lapse GPR surveys with enhanced data postprocessing offer a practical and nondestructive way of mapping LPF networks in the field, thereby providing a potentially significant enhancement in our ability to study complex subsurface flow processes across the landscape.",

        "abstract": "Analysis based on the holistic multiple time series system has been a practical and crucial topic. In this paper, we mainly study a new problem that how the data is produced underneath the multiple time series system, which means how to model time series data generating and evolving rules (here denoted as semantics). We assume that there exist a set of latent states, which are the system basis and make the system run: data generating and evolving. Thus, there are several challenges on the problem: (1) How to detect the latent states; (2) How to learn the rules based on the states; (3) What the semantics can be used for. Hence, a novel correlation field-based semantics learning method is proposed to learn the semantics. In the method, we first detect latent state assignment by comprehensively considering kinds of multiple time series characteristics, which contain tick-by-tick data, temporal ordering, relationship among multiple time series and so on. Then, the semantics are learnt by Bayesian Markov characteristic. Actually, the learned semantics could be applied into various applications, such as prediction or anomaly detection for further analysis. Thus, we propose two algorithms based on the semantics knowledge, which are applied to make next-n step prediction and detect anomalies respectively. Some experiments on real world data sets were conducted to show the efficiency of our proposed method.",

        "abstract": "Anonymous communication technique is one of the main privacy-preserving techniques, which has been widely used to protect Internet users' privacy. However, existing anonymous communication systems are particularly vulnerable to traffic analysis, and researchers have been improving unobservability of systems against Internet censorship and surveillance. However, how to quantify the degree of unobservability is a key challenge in anonymous communication systems. We model anonymous communication systems as an alternating turing machine, and analyze adversaries' threat model. Based on this model, this paper proposes a relative entropy approach that allows to quantify the degree of unobservability for anonymous communication systems. The degree of unobservability is based on the probabilities of the observed flow patterns by attackers. We also apply this approach to measure the pluggable transports of TOR, and show how to calculate it for comparing the level of unobservability of these systems. The experimental results show that it is useful to evaluate the level of unobservability of anonymous communication systems. Finally, we present the conclusion and discuss future work on measuring unobservability in anonymous communication systems.",

Service resource, the knowledge that can help users get access to the service finally, is the focus of accessibility confrontation between the adversary and Internet services. Most of current resource distribution strategies adopt the \u201cmany access points\u201d design and limit the number of service resources distributed to any user. However, current design is vulnerable to enumeration attack where an adversary can enumerate many service resources under the disguise of many pseudonyms (Sybil identities). To mitigate this challenge, an adaptive resource distribution strategy based on trust management is proposed in this paper. Under this strategy, user\u2019s trust is adjusted according to his behavior. Both client puzzle and the resources assigned to the user are dynamically generated according to his trust value. Simulation result indicates that, this strategy can distinguish honest users from adversary Sybils, thus increasing the difficulty for an attacker to enumerate service resources while ensuring access to service for honest users.",

Study indicated that the automata states have specific statistical access characteristics in practice. Accordingly, a series of algorithms based on statistical characteristics for building hybrid finite automata, named HybridFA, are proposed. This work completes partial states of the AC automata according to different features, including access frequency, state hierarchy, and combined characteristics respectively. Experimental results on the real-world datasets like Snort, ClamAV, and URL show that the storage space of HybridAC is reduced to less than 5% of the space cost by the advanced AC automata. Furthermore, HybridFA based on combined characteristics achieves the superior performance on matching speed and robustness comparing to other proposed algorithms.",

However, we recently have observed that various malicious information, such as computer virus and rumors, were broadly spread via social networks. For better controlling the spread of malicious information, it is critical to develop effective methods to locate the diffusion source nodes in social networks. Many pioneer works have explored the source locating problem, but they mostly rely on the assumption that there is only a single source node. In this paper, we present an approximate multi-source locating algorithm by first introducing a new reverse propagation model to detect the recovered and unobserved infected nodes, and then developing a community detection method to cluster the extended infected nodes (including recovered nodes and infected nodes) into multiple infected communities. In doing so, we can identify the source nodes by using the maximum likelihood estimation on each infected community. Numerical simulations on both synthetic and real networks show the performance of the proposed method.",

As a new environmental-purifying technology, semiconductor photocatalytic oxidation technology has arosen worldwide attention. However, conventional photocatalyst exhibits poor utilization of solar energy and low efficient of photogenerated charge separation, which restricts the practical application of the technology. Therefore, it is still a challenging topic to design and synthesize visible-light-response photocatalytic materials with higher utilization efficiency of solar energy. Besides tuning synthesis method (by controlling particle size, morphology, crystallinity and other microstructures, etc), modification is a crucial strategy for the activity enhancement of photocatalyst. In this paper, we reviewed the basic mechanism for the photocatalyst modification from the view of semiconductor energy structure. Taking consideration of the basic mechanism and process of photocatalysis, there are two key modification strategies: chemical structure modification (energy band modification) to broaden the light absorption and surface modification (surface sensitization, semiconductor combinations and noble metal deposition) to increase life-time of carrier. Suitable band structure is responsible for the visible-light harvesting and effective separation of carrier of semiconductor photocatalyst.",

The patient experienced recurrent pneumonia and acute respiratory distress syndrome (ARDS) from 4 months of age. Immunological evaluation revealed a normal level of serum IgM, with significantly low levels of serum IgG and IgA. Genetic analysis of the CD40L gene revealed a splice mutation in exon 5 at the nucleotide position 410 (c.410-2A>G), which has never been reported previously in the literature. Following treatment with regular intravenous immunoglobulin (IVIG) replacement therapy every 3 to 4 weeks and infection prophylaxis with trimethoprim-sulfamethoxazole during follow-up, the patient's immunoglobulin level returned to normal with no pulmonary infection. The eosinophil count also returned to normal after a small dose of steroid agent treatment was administered orally for 5 months. In summary, X-linked hyper-IgM syndrome with CD40L gene mutation presenting with eosinophilia may be successfully treated using IVIG replacement therapy and a small dose of steroid agent.",

        "abstract": "Obtaining accurate ultrasonically estimated displacements along both axial (parallel to the acoustic beam) and lateral (perpendicular to the beam) directions is an important task for various clinical elastography applications (e.g., modulus reconstruction and temperature imaging). In this study, a partial differential equation (PDE)-based regularization algorithm was proposed to enhance motion tracking accuracy. More specifically, the proposed PDE-based algorithm, utilizing two-dimensional (2D) displacement estimates from a conventional elastography system, attempted to iteratively reduce noise contained in the original displacement estimates by mathematical regularization. In this study, tissue incompressibility was the physical constraint used by the above-mentioned mathematical regularization. This proposed algorithm was tested using computer-simulated data, a tissue-mimicking phantom, and in vivo breast lesion data. Computer simulation results demonstrated that the method significantly improved the accuracy of lateral tracking (e.g., a factor of 17 at 0.5% compression). From in vivo breast lesion data investigated, we have found that, as compared with the conventional method, higher quality axial and lateral strain images (e.g., at least 78% improvements among the estimated contrast-to-noise ratios of lateral strain images) were obtained. Our initial results demonstrated that this conceptually and computationally simple method could be useful for improving the image quality of ultrasound elastography with current clinical equipment as a post-processing tool.",

This model is commonly used in combustion problems. However, previous numerical methods are mainly based on a second order finite difference method. This is because the positivity-preserving property can hardly be satisfied for high-order ones, leading to incorrect blow-up time and blow-up sets. Recently, we have applied discontinuous Galerkin methods to linear hyperbolic equations involving \u03b4-singularities and obtained good approximations. For nonlinear problems, some special limiters are constructed to capture the singularities precisely. We will continue this approach and study parabolic equations with blow-up solutions. We will construct special limiters to keep the positivity of the numerical approximations. Due to the Dirichlet boundary conditions, we have to modify the numerical fluxes and the limiters used in the schemes. Numerical experiments demonstrate that our schemes can capture the blow-up sets, and high-order approximations yield better numerical blow-up time.",

However, MIH is based on the dataset codes uniform distribution assumption, and will lose efficiency in dealing with non-uniformly distributed codes. Besides, there are lots of results sharing the same Hamming distance to a query, which makes the distance measure ambiguous. In this paper, we propose a data-oriented multi-index hashing method. We first compute the covariance matrix of bits and learn adaptive projection vector for each binary substring. Instead of using substrings as direct indices into hash tables, we project them with corresponding projection vectors to generate new indices. With adaptive projection, the indices in each hash table are near uniformly distributed. Then with covariance matrix, we propose a ranking method for the binary codes. By assigning different bit-level weights to different bits, the returned binary codes are ranked at a finer-grained binary code level. Experiments conducted on reference large scale datasets show that compared to MIH the time performance of our method can be improved by 36.9%-87.4%, and the search accuracy can be improved by 22.2%.",

        "abstract": "P2P collusive piracy, where paid P2P clients share the content with unpaid clients, has drawn significant concerns in recent years. Study on the follow relationship provides an emerging track of research in capturing the followee (e.g., paid client) for the blocking of piracy spread from all his followers (e.g., unpaid clients). Unfortunately, existing research efforts on the follow relationship in online social network have largely overlooked the time constraint and the content feedback in sequential behavior analysis. Hence, how to consider these two characteristics for effective P2P collusive piracy prevention remains an open problem. In this paper, we proposed a multi-bloom filter circle to facilitate the time-constraint storage and query of P2P sequential behaviors. Then, a probabilistic follow with content feedback model to fast discover and quantify the probabilistic follow relationship is further developed, and then, the corresponding approach to piracy prevention is designed. The extensive experimental analysis demonstrates the capability of the proposed approach.",

        "abstract": "Aims The prevalence and risk factors of urinary incontinence (UI) for post-stroke inpatients remain unclear. In this study, we aimed to investigate the risk factors associated with the development of UI for post-stroke inpatients in southern China. Design Cross-sectional survey. Subjects and Methods A total of 711 post-stroke patients from neurological units at 8 different hospitals in Guangzhou, a city in southern China, were interviewed face to face. Data were collected by a self-designed questionnaire which includes sociodemographic variables, characteristics of stroke, and medical history. Results The prevalence of UI among post-stroke inpatients was 44.3%. By multivariate logistic regression, we found that major risk factors for UI included health care assistant care (OR-=-3.935), hemorrhagic stroke (OR-=-1.755), mixed stroke (OR-=-2.802), parietal lobe lesion (OR-=-1.737), chronic cough (OR-=-2.099), aphasia (OR-=-3.541), and post-stroke depression (OR-=-3.398). Conclusions The prevalence of UI among post-stroke inpatients is high. Stroke inpatients looked after by health care assistant, hemorrhagic stroke, mixed stroke, parietal lobe lesion, chronic cough, aphasia, and post-stroke depression were high-risk groups for UI. These patients should be targeted when planning intervention programs.",

        "abstract": "Considerable efforts have been devoted to the development of dynamic origin-destination (OD) estimation models, which are a key step to realizing self-adaptive traffic control systems for urban traffic management. However, most of the models proposed to date estimate OD flows based on a single traffic data source, and their performance is limited by the coverage and accuracy of traffic sensors. The inherent difficulty in estimating the dynamic traffic assignment matrix means that dynamic OD estimation remains a challenge for real-life applications. This paper proposes the use of a Kalman filter for dynamic OD estimation using multi-source sensor data. The dynamic characteristic of changing OD flow over time is analyzed, and the problem of dynamic OD estimation is converted to a problem of estimating OD structural deviation. The resulting dynamic relationship between traffic volume and OD structural deviation is then used to establish the Kalman filter model. An improved traffic assignment approach is developed and embedded into the measurement equation of the Kalman filter model to enable dynamic updating of the traffic assignment matrix. A dual self-adaptive mechanism based on the Kalman filter is used to calibrate the model. The proposed method was implemented on a real-life traffic network in the downtown area of Kunshan City, China. The results show that the proposed method is more accurate than, and outperforms, the traditional link-volume-based and turning-movement-based methods.",

Here we aim to determine the prognostic significance of autophagy in colorectal carcinoma patients, thereby allowing more rational development of therapeutic strategies. Through transmission electron microscopy, our data first demonstrated high frequency of defective mitochondria was strongly associated with poor overall survival in colorectal carcinoma. Next immunohistochemical study showed the expressions of Beclin 1, LC3B and Bcl-xL in both the center of tumor and adjacent noncancerous mucosal region were also correlated with overall survivals. We developed an autophagy signature for prognosis based on these three major autophagic proteins, further analysis suggested it was an independent prognostic biomarker and had its value even within single clinical stage. Combined TNM stage and this signature could significantly improve the accuracy of survival prognosis. To validate these immunohistochemical results, an internal testing cohort and an independent population were also included. Our findings suggest that autophagy plays an important role in the clinical cancer progression. Therefore autophagic proteins may be valuable prognostic biomarkers in the therapy of colorectal carcinoma and possibly other types of cancers.",

        "abstract": "Cutterhead is the core component of TBM tunneling equipment, which endures strong, multi-point distributed impact loads when the TBM tunnels, owing to the extreme surrounding rock environment of high hardness, high temperature and high quartz content. For this reason, the cutterhead works in an extremely severe vibration environment, which leads to engineering fault by a large area crack damage before the service life. Hence, the study on life prediction of TBM cutterhead under the impact loads is a core part of cutterhead design. This paper combines with the technology of system dynamics, linear elastic fracture mechanics and cumulative theory of fatigue damage, for the first time, proposes a method of fatigue crack propagation life prediction for the large and complex structures. In this paper, the TBM cutterhead of an actual project is taken as an example, to predict the fatigue crack propagation life of cutterhead piece and analyze the influences of plate thicknesses on fatigue life, then a new improved scheme of cutterhead structure is presented. The results show that the fatigue crack propagation life of actual cutterhead is 26.6 km, which is able to meet the requirement of 20 km service life. Moreover, the upper cover plate thickness has the greatest influence on cutterhead fatigue crack propagation life, with the thickness increasing 10%, the life increases nearly by 1.24 times. Then, the other influencing factors are as follows: thickness of the main support plate, thickness of the annular support plate and thickness of the support plate, whereas the influence of the lower cover plate thickness on fatigue life is minimal. Furthermore, the plate thickness limit sizes meeting the life requirement are obtained, and a new structure modified scheme of cutterhead is proposed. Compared with the original scheme, the new cutterhead scheme meets the requirements of structural strength and service life with 8.08% weight decrease, which achieves life determination design and lightweight design. The proposed method of fatigue crack propagation life prediction is feasible in the design and application stage of TBM cutterhead, besides, it is flexible enough and can also be applied in damage strength assessment, dynamic parameters optimization and establishment of nondestructive inspection cycle for the other large and complex structure, and takes on stronger project value and generality.",

However, it also needs additional signal sources to transmit artificial noise. In this paper, we investigate the multiple-input single-output (MISO) cognitive radio system where two secondary links secure each other's communication. Each secondary transmitter (ST) sends intended messages to its own receiver while acts as a friendly jammer to the other CRN. Our target is to maximize the worst-user's secrecy rate while limiting the interference in the direction of the primary receiver. We solve the problem through a sequence of convex semidefinite programs (SDPs) under individual power constraints. We also introduce two sub-optimal zero-forcing (ZF) beamforming methods, one of which solves the problem based on SDP and the other adopts the approach of Pareto-optimal parameterization in a more computationally efficient way.",

        "abstract": "Zijuan (Camellia sinensis var. assamica) is the most well-known representative of purple leaf coloured anthocyanin-rich tea cultivars in China. Herein, its anthocyanin composition has been investigated for the first time. Eight anthocyanins, pelargonidin-3,5-diglucoside, cyanidin-3- O-galactoside, cyanidin-3- O-glucoside, delphinidin, cyanidin, pelargonidin, peonidin, and malvidin were identified using HPLC and LC-MS and by comparison of their retention times, elution order and MS spectra to authentic standards. Cyanidin-3- O-galactoside was found to be the most abundant. Anthocyanins are generally enriched in tender Zijuan tea leaves, and the green tea processing, especially roasted green tea, can effectively retain the vast majority of the anthocyanins originally present in the fresh leaves compared with those for Oolong tea and black tea. The antioxidant activities of tea infusions made from different kinds of Zijuan tea products were determined by measuring their DPPH radical scavenging capacity, ABTS radical scavenging capacity, ferric reducing antioxidant power (FRAP), and cellular antioxidant activity (CAA). Generally Zijuan green tea has stronger antioxidant activity than Zijuan Oolong tea and Zijuan black tea. Moreover, a significant positive correlation was observed between the total anthocyanins and antioxidant activity as measured by DPPH. ( r = 0.896), ABTS. <sup>+</sup> ( r = 0.933), FRAP ( r = 0.907) and CAA ( r = 0.967) assays, suggesting that anthocyanins contribute greatly to the antioxidant activity of Zijuan tea products.

        "abstract": "Biomass is a ubiquitous green renewable resource with good storability, however, biomass power generation (BPG) is seldom used in remote stand-alone microgrid (SAMG) systems. According to the operating characteristics of distributed generators, a novel double-mode optimal coordinated control approach for wind/biomass/diesel/ battery SAMG was proposed in this paper. The control scheme consists of two modes: the economic optimization dispatch strategy at normal operation mode and the emergency power control strategy at large disturbance mode. The diesel operating point was set to match the instantaneous net load around the set-point power with high fuel efficiency, and to provide the system operating reserve capacity. Output power of BPG was depended on the net load to achieve the effectively combined power generation with wind turbine generators, and thus to obtain the high penetration of renewable resources. A novel control method for battery energy storage system (BESS) was also presented, which gives priority to emergency power control, to optimize the BESS capacity size and operation conditions. For a remote SAMG, the simulation studies on both the lifecycle energy dispatch strategies and the transient stability analysis under typical scenarios are carried out to demonstrate the performance of the proposed methods.",

The 72 h EC<inf>50</inf> of the most active extracts were measured. The results demonstrated the obvious species-specific activities of macrophytes on algae. Anabaena flosaquae and Aphanizomenon flosaquae was sensitive to the three macrophytes extracts, while unicellular M. aeruginosa was only sensitive to A. calamus and O. javanica extracts under the extracts concentration of 100 mg\u00b7L<sup>-1</sup>. Only the extract of A. calamus roots showed high growth inhibition on the natural phytoplankton assemblages in Dianchi Lake (Microcystis water bloom). The 72 h EC<inf>50</inf> of A. calamus roots hexane extract on unicellular M. aeruginosa was 13.59 mg\u00b7L<sup>-1</sup>, while that on natural phytoplankton assemblages was 48.75 mg\u00b7L<sup>-1</sup>. These results demonstrated that the growth inhibitory activities of allelochemicals on unicellular M. aeruginosa cannot instead of the efficacies for controlling Microcystis bloom completely. And according to the different sensitivities of Microcystis species, the colonial Microcystis strains or natural Microcystis bloom will be proposed as the target organism when searching for Microcystis bloom control.",

        "abstract": "In this work, a novel, rapid and ultrasensitive chemiluminescence (CL) method is established for sensing the fluorescent dye calcein in water, which is composed of peroxynitrous acid (ONOOH), calcein and modified kaolin. This is the first time that the modified kaolin is applied to CL analysis and used as catalyst and adsorbent in the ONOOH-calcein-modified kaolin CL system to enhance the signals. In this work, we have optimized the conditions and found that the enhanced CL intensity is proportional to the concentration of calcein in the range of 0.1-100 \u03bcM. The limit of detection is 0.01 \u03bcM. The proposed CL sensing method is successfully applied to determine calcein in simulative samples prepared from tap water and river water with recoveries of 96.9-105.2%. The primary CL mechanism is proposed based on CL spectra, powder X-ray diffraction (XRD), high-resolution transmission electron microscopes (HRTEM) and fluorescent spectra, etc. The modified kaolin has a porous structure along with abundant oxygen vacancies, which provides a desirable environment where CL can be catalyzed easily. The CL enhancement is also attributed to the increased efficiency of CL resonance energy transfer (CRET) and the greater ability of calcein to absorb energy and emit it through fluorescence. The newly established ONOOH-calcein-modified kaolin CL system provides not merely an ultrasensitive approach to sensing calcein but also the application potential in determinating the substances which could have coupling interaction with the reagents in the CL system.",

        "abstract": "The endothelial PAS domain protein 1 (EPAS1) gene functions to sense the blood oxygen level by regulating the hypoxia-inducible transcription factor pathway, and single nucleotide polymorphisms (SNPs) of EPAS1 have been found to have a strong and positive selection in the adaptation of the native Tibetan highland population to high-altitude hypoxia. The aim of the present study was to investigate the effect of EPAS1 SNPs on the risk of acute mountain sickness (AMS) and the physiological responses to acute high-altitude hypoxia in lowland humans. Three tag SNPs (rs6756667, rs13419896 and rs4953354; minor allele frequency, \u22655%) were selected and genotyped in 603 unrelated Han Chinese men, who had traveled to Lhasa (a high-altitude hypoxia environment) by plane, using a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry method. The data showed that the EPAS1 rs6756667 wild-type GG homozygous genotype was associated with elevated AMS risk compared with the AA and AG genotypes (odds ratio, 1.815; 95% confidence interval, 1.233-2.666; P=0.0023) using the dominant-model analysis. EPAS1 rs6756667 GG genotypes were also associated with higher levels of hemoglobin, red blood cells and hematocrit than those carrying the AG heterozygote during AMS development. These findings indicate that EPAS1 SNPs play a role in the physiological effects of AMS, and these effects could be further evaluated as a therapeutic strategy to control acute hypoxia-related human diseases.",

However, the lack of biomarkers for this disease still constitutes a bottleneck in the clinical diagnosis. Here, ultra-high performance liquid chromatography coupled with Q-TOF mass spectrometry was applied to study plasma metabolite profiling from 57 HAPE and 57 control subjects. 14 differential plasma metabolites responsible for the discrimination between the two groups from discovery set (35 HAPE subjects and 35 healthy controls) were identified. Furthermore, 3 of the 14 metabolites (C8-ceramide, sphingosine and glutamine) were selected as candidate diagnostic biomarkers for HAPE using metabolic pathway impact analysis. The feasibility of using the combination of these three biomarkers for HAPE was evaluated, where the area under the receiver operating characteristic curve (AUC) was 0.981 and 0.942 in the discovery set and the validation set (22 HAPE subjects and 22 healthy controls), respectively. Taken together, these results suggested that this composite plasma metabolite signature may be used in HAPE diagnosis, especially after further investigation and verification with larger samples.",

However, the compounds responsible for the seasonal variation of metabolic pattern and taste quality are far from clear. This study compared the metabolite profiles of green teas of nine varieties that were plucked in spring, summer, and autumn by using ultraperformance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) on a reversed phase column. A multivariate analysis indicated distinct differences among the metabolite phenotypes of teas harvested in different seasons. Heat-map analysis and metabolic pathway analysis demonstrated that flavan-3-ols, theasinensins, procyanidins, quercetin-O-glycosides, apigenin-C-glycosides, and amino acids exhibited sharp seasonal fluctuations. An equivalent quantification of tea tastes showed that in summer and autumn teas, the bitterness and astringency were significantly elevated, whereas umami declined. Metabolite content comparisons and partial least-squares analysis suggested that several flavonoids and amino acids are mainly responsible for the seasonal variations in taste quality.",

        "abstract": "AIM: To study the refractive status characteristics aftser cataract surgery and the correlation between preoperative anterior chamber depth (ACD) and refractive status. METHODS: Ninety-six cases of patients with cataract were randomly divided into two groups. The patients in phacoemulsification group were treated with phacoemulsification combined intraocular lens (IOL) implantation while the patients in small incision group were treated by small incision extracapsular cataract extraction combined with IOL implantation. Changes in ACD and postoperative refractive status and refractive fully corrected value were counted and the correlation of them were analyzed. RESULTS: ACD of the phacoemulsification group s deepened 0.74mm while that of the small incision group deepened 0.78mm after treatment and there was no significant difference (P>0.05). After operation, the ACD of two groups significantly deepened (P<0.05). The postoperative visual acuity of two groups were significantly better than the uncorrected visual acuity of two groups (P<0.05). The postoperative refraction of two groups patients were mainly 0~+1.0D (41.67% and 54.16%) and +1.25~+2.0D (43.75% and 33.33%) (P>0.05). CONCLUSION: ACD is significant deepened after operation. Surgeon needs full consideration of changes to improve the refractive IOL calculation accuracy.",

        "abstract": "Aim: To investigate the inhibitory effects of gossypol on migration in gastric carcinoma cell lines and its mechanisms. Methods: Gastric carcinoma cells were treated with gossypol at different concentrations. The effects of gossypol on cells proliferation were measured using the MTT assay. The migration of gastric carcinoma cells was detected by transwell assay. The activation of Akt/\u03b2-catenin pathway and the expressions of pathway related proteins (p-Akt, \u03b2-catenin, cyclin D1, MMP-2, E-cadherin and vimentin) were detected by Western blot. Results: Gossypol treatment could significantly inhibit the proliferation of gastric carcinoma cells in a dose-dependent manner. Transwell assay showed that the migration ability of gastric carcinoma cells was significantly decreased. The inhibitory effect of gossypol on cells migration was more significant than the effect of gossypol on cells proliferation. Compared with the control group, treatment with gossypol significantly suppressed the expressions of p-Akt,\u03b2-catenin, cyclin D1, MMP-2 and vimentin protein, whereas the expression of E-cadherin was significantly up-regulated in gastric carcinoma cells in a dose-dependent manner. Conclusion: These results demonstrate that gossypol represses cell migration of gastric carcinoma cells through the down-regulation of the activity of Akt/\u03b2-catenin pathway.",

        "abstract": "Background Tuberculous meningitis is the most lethal form of tuberculosis, but current diagnostic methods are inadequate. The measurement of cerebrospinal fluid parameters can provide early information for diagnosis. The present study focus on the validity of the cut-off value of cerebrospinal fluid parameters according to the Lancet consensus of scoring system for diagnosis of tuberculous meningitis. Method A total of 100 confirmed patients were enrolled in this study. We evaluated significance of protein level (>1 g/l), chloride level (<120 mmol/l), glucose level (<2.2 mmol/l), cell counts (10-500 cells/\u03bcl, lymphocytic pleocytosis (>50%), and neutrophil predominance (>50%) in early diagnosis of tuberculous meningitis. Result The cerebrospinal fluid parameters were significantly different between the tuberculous meningitis group and the control group. The independent factors for diagnosis of tuberculous meningitis were protein level (>1 g/l), glucose level (<2.2 mmol/l), cell counts (10-500 cells/\u03bcl and neutrophil predominance >50%). Neutrophil predominance (>50%) performed the best with the area under the curve of 89.7%. The sensitivity of protein level (>1 g/l), glucose level (<2.2 mmol/l), cell counts (10-500 cells/\u03bcl) and neutrophil predominance (>50%) for diagnosis of tuberculous meningitis were 66%, 58%, 86%, and 54%, and the specificity were 84%, 98%, 32%, and 98%. There are 84% patients in tuberculous meningitis group at least having two positive parameters among the four independent parameters, while only 10% in control group. Conclusion The cerebrospinal fluid parameters can help the clinicians to make a prompt diagnosis in the early stage of the disease. Diagn. Cytopathol. 2015;43:701-704.",

        "abstract": "Osteoclast-associated receptor (OSCAR) is widely expressed on human myeloid cells. Collagen types (Col)I, II, and III have been described as OSCAR ligands, and ColII peptides can induce costimulatory signaling in receptor activator for NF-\u03baB-dependent osteoclastogenesis. In this study, we isolated collagen as an OSCAR-interacting protein from the membranes of murine osteoblasts. We have investigated a functional outcome of the OSCAR-collagen interaction in human monocyte-derived dendritic cells (DCs). OSCAR engagement by ColI/II-induced activation/maturation of DCs is characterized by upregulation of cell surface markers and secretion of cytokines. These collagen-matured DCs (Col-DCs) were efficient drivers of allogeneic and autologous naive T cell proliferation. The T cells expanded by Col-DCs secreted cytokines with no clear T cell polarization pattern. Global RNA profiling revealed that multiple proinflammatory mediators, including cytokines and cytokine receptors, components of the stable immune synapse (namely CD40, CD86, CD80, and ICAM-1), as well as components of TNF and TLR signaling, are transcriptional targets of OSCAR in DCs. Our findings indicate the existence of a novel pathway by which extracellular matrix proteins locally drive maturation of DCs during inflammatory conditions, for example, within synovial tissue of rheumatoid arthritis patients, where collagens become exposed during tissue remodeling and are thus accessible for interaction with infiltrating precursors of DCs.",

        "abstract": "The loss of photoreceptors is the defining characteristic of many retinal degenerative diseases, but the mechanisms that regulate photoreceptor cell death are not fully understood. Here we have used the 661W cone photoreceptor cell line to ask whether exposure to the terminal complement complex C5b-9 induces cell death and/or modulates the sensitivity of these cells to other cellular stressors. 661W cone photoreceptors were exposed to complete normal human serum following antibody blockade of CD59. Apoptosis induction was assessed morphologically, by flow cytometry, and on western blotting by probing for cleaved PARP and activated caspase-3. Necroptosis was assessed by flow cytometry and Sirtuin 2 inhibition using 2-cyano-3-[5-(2,5-dichlorophenyl)-2-furyl]-N-5-quinolinylacrylamide (AGK2). The sensitivity of 661W cells to ionomycin, staurosporine, peroxide and chelerythrine was also investigated, with or without prior formation of C5b-9. 661W cells underwent apoptotic cell death following exposure to C5b-9, as judged by poly(ADP-ribose) polymerase 1 cleavage and activation of caspase-3. We also observed apoptotic cell death in response to staurosporine, but 661W cells were resistant to both ionomycin and peroxide. Interestingly, C5b-9 significantly increased 661W sensitivity to staurosporine-induced apoptosis and necroptosis. These studies show that low levels of C5b-9 on 661W cells can induce apoptosis, and that C5b-9 specifically sensitizes 661W cells to certain apoptotic and necroptotic pathways. Our observations provide new insight into the potential role of the complement system in photoreceptor loss, with implications for the molecular aetiology of retinal disease.",

To investigate the role of the 5-hmC DNA modification with regard to the onset of SLE, we compared the levels 5-hmC between SLE patients and normal controls. Whole blood was obtained from patients, and genomic DNA was extracted. Using the hMeDIP-chip analysis and validation by quantitative RT-PCR (RT-qPCR), we identifed the differentially hydroxymethylated regions that are associated with SLE. There were 1,701 genes with significantly different 5-hmC levels at the promoter region in the SLE patients compared with the normal controls. The CpG islands of 3,826 genes showed significantly different 5-hmC levels in the SLE patients compared with the normal controls. Out of the differentially hydroxymethylated genes, three were selected for validation, including TREX1, CDKN1A and CDKN1B. The hydroxymethylation levels of the three genes were confirmed by RT-qPCR. The results suggested that there were significant alterations of 5-hmC in SLE patients. Thus, these differentially hydroxymethylated genes may contribute to the pathogenesis of SLE. These findings show the significance of 5-hmC as a potential biomarker or promising target for epigenetic-based SLE therapies.",

        "abstract": "Membranous nephropathy (MN) is a common cause of nephrotic syndrome in adults and the second leading cause of end\u2011stage renal disease due to primary glomerulonephritis. The aim of the present study was to identify potential biomarkers of MN and further characterize these proteins by Gene Ontology (GO) analysis. Isobaric tags for relative and absolute quantification were used to compare the protein levels in tissues from MN patients and healthy individuals, and the combined samples were subsequently separated by specialized communications exchange. Mass spectrometry data acquisition was conducted using a 4800 Plus MALDI TOF/TOF tandem mass spectrometry device, and the results were subjected to statistical analysis. A total of 1,903 proteins were identified, with 423 proteins exhibiting a difference of >1.5\u2011fold compared with the control group. Of these, 202 proteins were upregulated, while 221 proteins were downregulated. In conclusion, GO enrichment analysis revealed that the differentially expressed proteins were primarily mapped to the following GO terms: 'Immune response', 'immune effector process', 'activation of immune response' and 'positive regulation of immune system process'. The affected proteins may be associated with the pathogenesis of MN; thus, may represent candidate MN biomarkers.",

        "abstract": "The complex chemistry of coal pyrolysis is difficult to be captured by experimental techniques or simulated with the quantum mechanics computational methods. The emerging of both the large-scale coal models and the promising capability of reactive molecular dynamics (ReaxFF MD) motivated us to develop a new methodology by combining graphics processing unit (GPU)-enabled high performance computing with cheminformatics analysis in order to explore the coal pyrolysis mechanisms using ReaxFF MD. The methodology is rooted in two new software tools, GMD-Reax, the first GPU-enabled ReaxFF MD codes that make it practical to simulate large-scale models (\u223c10,000 atoms) on desktop workstations, and visualisation and analysis of reactive molecular dynamics (VARMD), the first software dedicated to analysis of detailed chemical reactions from the trajectories of ReaxFF MD simulation. With this methodology, reasonable product profiles and gas generation sequences of pyrolysis for bituminous coal models ranging from \u223c1000 to \u223c10,000 atoms (including the system with 28,351 atoms, one of the largest systems used in ReaxFF MD) have been obtained. The complex and detailed chemical reactions directly revealed by VARMD can provide further information on radical behaviours and their connection with pyrolysates. The methodology presented here offers a new and promising approach to systematically understand the complex chemical reactions in thermolysis of very complicated molecular systems.",

Currently, treatment options for the prevention and control of fatal H7N9 infections in humans remain limited. Here we characterize two human monoclonal antibodies (HuMAbs), HNIgGA6 and HNIgGB5, by screening a Fab antibody phage library derived from patients who recovered from H7N9 infection. Both antibodies exhibit high neutralizing activity against H7N9 virus in cells. Two amino acids in the receptor-binding site, 186V and 226L, are crucial for the binding of these two HuMAbs to viral haemagglutinin antigens. Prophylaxis with HNIgGA6 and HNIgGB5 confers significant immunity against H7N9 virus in a mouse model and significantly reduces the pulmonary virus titre. When administered post infection, therapeutic doses of the HuMAbs also provide robust protection against lethality. These antibodies might represent a potential alternative or adjunct to H7N9 pandemic interventions.",

        "abstract": "Introduction: The present study was designed to test the hypothesis that local angiotensin converting enzyme (ACE) was involved in the cardiac hypertrophy induced by sinoaortic denervation (SAD) in rats. Methods: Experiment 1: Six weeks after SAD of rats, components of renin-angiotensin system (RAS) in left ventricles were assayed by quantitative real-time PCR and Western blotting analysis. Experiment 2: Rats were divided into five groups treated as follows: (1) sham-operated group; (2) SAD group; (3) SAD group treated with angiotensin II type 1 receptor (AT1R) antagonist losartan (10 mg\u00b7kg<sup>-1</sup>\u00b7day<sup>-1</sup>, orally); (4) SAD group treated by ACE inhibitor ramipril (1 mg\u00b7kg<sup>-1</sup>\u00b7day<sup>-1</sup>, orally); (5) SAD group treated by ramipril and the B2-kinin receptor selective antagonist HOE-140 (0.25 mg\u00b7kg<sup>-1</sup>\u00b7day<sup>-1</sup>, subcutaneously). Results: SAD led to augmentation of the mRNA levels and protein expression of left ventricular ACE and AT1R. Both losartan and ramipril ameliorated SAD-induced left ventricular hypertrophy. Both losartan and ramipril abated oxidative stress, suppressed inflammation, and reduced expression TGF\u03b2-R in left ventricles. In addition, the protective effect of ramipril could be abolished by HOE-140. Conclusion: Local ACE is involved in the left ventricular hypertrophy induced by sinoaortic denervation in rats, via both angiotensin II/AT1R and bradykinin/B2R pathways.",

An improved hybrid topology utilizing the reverse voltage clamping of forward diodes and capacitor charge effect is designed to solve the unidirectional charge problem without the need to change the control and voltage balancing algorithm. By investigating the different current charge paths, the current blocking coefficient is defined as the ratio between arm equivalent DC voltage and alternating current (AC) voltage magnitude to indicate the blocking effect. The self-excited startup procedure is also designed according to the capacitor voltage in the uncontrollable rectifying process. The effectiveness of this topology is verified by MMC simulation results.",

        "abstract": "Background: No studies have been reported on children obesity prevalence of Guangzhou, one of the most urbanized areas in China. This study tracks the secular trends of obesity prevalence of children. Methods: The data were derived from the surveys on students\u2019 constitution and health carried out by government. Randomly, 3832 students in 2007, 13141 in 2008, 14052 in 2009, 13750 in 2010, and 15225 in 2011, aged 7-12 years, from urban primary school were examined. Anthropometric parameters were measured in all students. Results: The mean of body mass index increased significantly from 16.6 in 2008 to 16.8 in 2011 in the total group of children, and the total prevalence of overweight and obesity increased from 9.4 and 6.2 to 10.5 and 7.5 from 2007 to 2011, respectively. The minimum value of the mean body mass index and the overweight and obesity prevalence in the total age group all appeared in 2008. The prevalence of overweight and obesity in males was significantly higher than that in females in each year among the 5 years. Conclusion: Although the prevalence of children obesity in Guangzhou in 2011 is still lower than the average values of Chinese large coastal cities, a significant increase was found in their prevalence from 2007 to 2011 and the total obesity prevalence of children is even higher than that of adolescent. Furthermore, we found that the minimum value of overweight and obesity prevalence of the total group and almost all gender-specific age groups appeared in 2008.",

        "abstract": "Background: Kelp (Saccharina japonica) has been intensively cultured in China for almost a century. Its genetic improvement is comparable with that of rice. However, the development of its molecular tools is extremely limited, thus its genes, genetics and genomics. Kelp performs an alternative life cycle during which sporophyte generation alternates with gametophyte generation. The gametophytes of kelp can be cloned and crossed. Due to these characteristics, kelp may serve as a reference for the biological and genetic studies of Volvox, mosses and ferns. Results: We constructed a high density single nucleotide polymorphism (SNP) linkage map for kelp by restriction site associated DNA (RAD) sequencing. In total, 4,994 SNP-containing physical (tag-defined) RAD loci were mapped on 31 linkage groups. The map expanded a total genetic distance of 1,782.75 cM, covering 98.66% of the expected (1,806.94 cM). The length of RAD tags (85 bp) was extended to 400-500 bp with Miseq method, offering us an easiness of developing SNP chips and shifting SNP genotyping to a high throughput track. The number of linkage groups was in accordance with the documented with cytological methods. In addition, we identified a set of microsatellites (99 in total) from the extended RAD tags. A gametophyte sex determining locus was mapped on linkage group 2 in a window about 9.0 cM in width, which was 2.66 cM up to marker_40567 and 6.42 cM down to marker_23595. Conclusions: A high density SNP linkage map was constructed for kelp, an intensively cultured brown alga in China. The RAD tags were also extended so that a SNP chip could be developed. In addition, a set of microsatellites were identified among mapped loci, and a gametophyte sex determining locus was mapped. This map will facilitate the genetic studies of kelp including for example the evaluation of germplasm and the decipherment of the genetic bases of economic traits.",

The as-obtained catalyst can attain a high yield of carbamate up to 82%, and can also be recycled at least four times through a simple procedure. It was observed that the Mn doping to ceria can alleviate the catalyst deactivation in consecutive catalytic recycles. In this regard, the role of Mn doping in the ceria in the synthesis of the aliphatic carbamates was investigated by means of X-ray diffraction (XRD), Raman spectra, specific surface areas (BET), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), CO<inf>2</inf>-temperature programmed desorption (CO<inf>2</inf>-TPD) and in situ diffuse reflectance infrared Fourier transform (DRIFT). The characterization demonstrated that the presence of MnO<inf>x</inf> in the ceria can not only inhibit the formation of stable carbonate species on the surface of the catalyst but also promote the decomposition/consuming of the carbonaceous species during the synthesis of aliphatic carbamates so as to allow improvement of the recyclability of the catalyst.",

The immobilized tungsten-based catalyst was employed as an efficient catalyst for the one-pot synthesis of \u03b2-alkoxy alcohols from olefins and methanol with H<inf>2</inf>O<inf>2</inf>. Regarding the catalyst evaluation and the results of characterization by the various methods, it was demonstrated that the immobilization of tungsten peroxo complex was highly temperature-dependent. The tungsten peroxo complex can dissociate and diffuse into the liquid phase at reaction temperature, resulting in a homogeneous reaction. Nevertheless, the catalytically active species was anchored on the imidazole-functionalized silica by hydrogen bonding as the temperature was lowered to 0\u00b0C after the reaction, which thus offered a highly effective approach for recycling the catalyst for consecutive cycles. In addition, various olefins can be converted to the corresponding \u03b2-alkoxy alcohols with good conversion and selectivity under relative mild conditions by H<inf>2</inf>O<inf>2</inf>. Running hot and cold: A tungsten peroxo complex (see picture) can dissociate and diffuse into the liquid phase at the reaction temperature, resulting in a homogeneous reaction. After reaction, the catalytically active species was anchored on the functionalized silica by hydrogen-bonding as the temperature was lowered to 0\u00b0C. This offers an effective approach for catalyst recovery and recycling.",

Here we report the identification of a primase noncatalytic subunit, denoted PriX, from the hyperthermophilic archaeon Sulfolobus solfataricus. Like PriL, PriX is essential for the survival of the organism. The crystallographic analysis complemented by sensitive sequence comparisons shows that PriX is a diverged homologue of the C-terminal domain of PriL but lacks the iron-sulfur cluster. Phylogenomic analysis provides clues on the origin and evolution of PriX. PriX, PriL and PriS form a stable heterotrimer (PriSLX). Both PriSX and PriSLX show far greater affinity for nucleotide substrates and are substantially more active in primer synthesis than the PriSL heterodimer. In addition, PriL, but not PriX, facilitates primer extension by PriS. We propose that the catalytic activity of PriS is modulated through concerted interactions with the two noncatalytic subunits in primer synthesis.",

        "abstract": "Image reconstruction from undersampled k-space data accelerates magnetic resonance imaging (MRI) by exploiting image sparseness in certain transform domains. Employing image patch representation over a learned dictionary has the advantage of being adaptive to local image structures and thus can better sparsify images than using fixed transforms (e.g. wavelets and total variations). Dictionary learning methods have recently been introduced to MRI reconstruction, and these methods demonstrate significantly reduced reconstruction errors compared to sparse MRI reconstruction using fixed transforms. However, the synthesis sparse coding problem in dictionary learning is NP-hard and computationally expensive. In this paper, we present a novel sparsity-promoting orthogonal dictionary updating method for efficient image reconstruction from highly undersampled MRI data. The orthogonality imposed on the learned dictionary enables the minimization problem in the reconstruction to be solved by an efficient optimization algorithm which alternately updates representation coefficients, orthogonal dictionary, and missing k-space data. Moreover, both sparsity level and sparse representation contribution using updated dictionaries gradually increase during iterations to recover more details, assuming the progressively improved quality of the dictionary. Simulation and real data experimental results both demonstrate that the proposed method is approximately 10 to 100 times faster than the K-SVD-based dictionary learning MRI method and simultaneously improves reconstruction accuracy.",

Methods: In a prospective, randomized, controlled clinical trial, 120 cases of idiopathic oligoasthenospermia were enrolled and randomly assigned to the indomethacin group (n\u00a0=\u00a060) treated with indomethacin (25\u00a0mg, bid) and TAM group (n\u00a0=\u00a060) treated with TAM (10\u00a0mg, bid) for 3\u00a0months. Before and after treatment, we evaluated semen parameters, serum malondialdehyde (MDA) and total antioxidant capacity (TAC), seminal plasma MDA and TAC, spermatozoa intracellular reactive oxygen species (ROS), sperm succinate dehydrogenase (SDH) activity, sperm mitochondrial membrane potential (MMP), and sperm adenosine triphosphate (ATP) content. The independent t test and one-way repeated measures analysis of variance were used to compare the variables between and within two groups. Results: In the indomethacin group, the percentage of progressive motile sperms, total motility, sperm MMP, and ATP content were increased significantly after 3-month treatment (P\u00a0<\u00a00.05). In the TAM group, total sperm count, sperm concentration, the percentage of progressive motile sperms, total motility, serum and seminal plasma TAC, sperm MMP, and ATP content were significantly improved or increased (P\u00a0<\u00a00.05), while spermatozoa intracellular ROS was significantly decreased (P\u00a0<\u00a00.05). Compared to the indomethacin group, TAM treatment showed better improvement in total sperm count, sperm concentration, serum TAC, seminal plasma TAC, spermatozoa intracellular ROS, and sperm SDH activity. Conclusions: TAM treatment can significantly improve sperm quality, which is achieved through alleviating oxidative stress, improving sperm mitochondrial functionality, and subsequently increasing sperm motility.",

        "abstract": "Background: The etiology and pathogenesis of hemorrhoids is unclear, although hemorrhoids are a worldwide disease in men and women, with peak prevalence at 45\u201365 years of age. Hemorrhoidal cushions as the anal venous plexi are normal anatomical structures from infancy. This study attempts to reveal the angiodysplasia and other pathological changes in association with different degrees of symptomatic hemorrhoids. Materials and methods: A total of 281 patients with internal hemorrhoids from degree I to IV underwent hemorrhoidectomy. The vascular changes were analyzed by microscopic assessment and software analysis, with Masson\u2019s trichrome, CD34, and smooth muscle actin. Results: The hemorrhoidal tissues exhibited abnormal vessels in the mucosae and submucosae that we termed them as myofibrotic malformation vessels (MMVs). MMVs are not ascribed to arteries or veins because they exhibit enlarged and tortuous lumens with smooth muscle dysplasia and fibrotic deposition in the walls without overlying mucosal ulceration. The muscularis mucosae also showed smooth muscle dysplasia and fibrosis, even if it were interrupted by the intruding MMVs. The statistical data indicated that the severity of all the changes correlate positively with the progression of hemorrhoids (P<0.001). Hemorrhoidal patients are prone for reoccurrence even with prolapsing hemorrhoid when compared with the conventional hemorrhoidectomy. Multiple logistic regression analysis showed that MMVs in mucosal propria, mean thickness of mucosal muscularis layer, and fibrotic changes in MMV were independent risk factors for MMVs in hemorrhoidal disease. Conclusion: MMVs and muscularis mucosae dysplasia reciprocally contribute to hemorrhoidal exacerbation. The novel findings of this study propose that the characteristic features of MMVs and muscularis mucosae dysplasia of the anorectal tube ultimately cause symptomatic hemorrhoids, which could affect the clinical management of hemorrhoidal disease through the use of surgery to target the malformed vessels.",

Understanding the molecular mechanism of the invasion behavior of glioblastoma is essential for the development of effective treatment of the disease. In our present study, we found that the expression levels of a homeobox transcription factor, MSX1, were significantly reduced in glioblastoma compared to normal brain tissues. The levels of MSX1 in glioblastoma tissues were also correlated with the survival of the patients. In cultured glioblastoma cells, MSX1 was a negative regulator of cell migration and invasion. Loss of MSX1 enhanced cell migration and induced mesenchymal transition as characterized by the downregulation of E-cadherin and the upregulation of N-cadherin. Overexpression of MSX1 on the other hand led to the inhibition of both cell migration and mesenchymal transition. We also found that MSX1 was able to inhibit the Wnt/\u03b2-catenin signaling pathway, and that the ability to regulate the Wnt/\u03b2-catenin signaling pathway is critical for MSX1 to suppress glioblastoma cell migration and invasion.",

        "abstract": "Soil wind erosion is a serious concern in agricultural regions. Wind erosion is of particular concern in Northeast China where a north continental monsoon climate is prevalent and land is prepared for seeding using an ancient ridge culture technique. Cultural reluctance to adopting a cropping strategy that leaves residues is also based on local population use of corn stalks as animal fodder and fuel. In order to evaluate the conservation effects of standing residue on controlling soil wind erosion, a 4-year study (2011-2014) was conducted near Changchun city in Northeast China. Four experimental treatments were used: un-fixed corn residue coverage (shattering/cutting the corn stalks into small sections and spreading them on the soil surface) and three treatments with the standing corn residue of different height for each treatment; 30-, 40- and 50-cm.<sup>1</sup>1The treatment with soil surface covered with small pieces of un-fixed, loose corn residue is designated as PA. The 30-cm high standing corn residue treatment is designated as PB; 40-cm treatment as PC; and 50-cm treatment as PD. Saltation probability is designated as Pi. The corn stalk residue above that which remained in each treatment was removed from the field as much as practical. The standing residue treatments also resulted in some soil coverage by fugitive leaves and small stalk pieces. The experimental design was four treatments replicated four times, with years as replicates. Soil loss from the un-fixed corn residue coverage treatment and soil sediment from the standing residue coverage treatments was measured. Standing residue with the heights of 30-, 40- and 50-cm increased mean aerodynamic roughness length (equivalent to the height at which the wind speed theoretically becomes zero) by 19.87, 43.77 and 61.62, respectively, and increased mean threshold wind speed by 11, 25 and 33%, respectively. Mean monthly soil loss mass balance for un-fixed corn residue was 1.27Mgha<sup>-1</sup>, and the mean monthly values for soil sediment mass balance were 0.725, 1.088 and 1.967Mgha<sup>-1</sup> for 30-, 40- and 50-cm standing residue treatments, respectively. These experiments indicate that standing residue conservation management can act as an effective way to control soil wind erosion, while providing a portion of corn stalks for the local population to continue using as animal fodder and fuel.",

        "abstract": "Optical coherence tomography angiography (Angio-OCT), mainly based on the temporal dynamics of OCT scattering signals, has found a range of potential applications in clinical and scientific research. Based on the model of random phasor sums, temporal statistics of the complex-valued OCT signals are mathematically described. Statistical distributions of the amplitude differential and complex differential Angio-OCT signals are derived. The theories are validated through the flow phantom and live animal experiments. Using the model developed, the origin of the motion contrast in Angio-OCT is mathematically explained, and the implications in the improvement of motion contrast are further discussed, including threshold determination and its residual classification error, averaging method, and scanning protocol. The proposed mathematical model of Angio-OCT signals can aid in the optimal design of the system and associated algorithms.",

Through analysis of x-ray diffraction spectra, cross-section transmission electron microscopy images and corresponding electron dispersive x-ray spectroscopy spectra in the novel stacked Ti/Al based Ohmic structure, the reactions between metals and the AlGaN layer were proven to be stable, uniform and continuous, which produced smooth contact interface.

        "abstract": "Compared with Ti/Al/Ni/Au Ohmic contacts, Ti/Al/Ti/Al/Ti/Al/Ti/Al/Ti/Al/Ni/Au with multiple Ti/Al stacks improved the thermal stability. Multiple-stacked Ohmic contacts showed lower degradation during long-time thermal aging at 600\u00b0C. The samples after degradation were tested with Transmission Electron Microscopy (TEM) to research the structural reasons. TEM results show that multiple stacks can avoid the producing of voids, which usually appear in the single Ti/Al stacked Ohmic metals. Al-Au alloy is believed to be the origin of the voids. While multiple Ti/Al stacks can reduce the size and quantity of Al-Au alloy and thus avoid the appearance of voids. The thermal stability enhancement of Ti/Al/..../Ti/Al/Ni/Au Ohmic contacts rendered it a great application in high temperature AlGaN/GaN HEMTs.",

        "title": "High breakdown AlGaN/GaN MOSHEMT with thermal oxidized Ni/Ti as gate insulator",
        "abstract": "Direct oxidation of composite Ni/Ti metal film structure for AlGaN/GaN MOSHEMT has been successfully demonstrated. In comparison with normal HEMT with Schottky-gate, transistors fabricated with this novel process exhibit three orders of magnitude reduction in gate leakage current, superior breakdown voltage ( V br = 471 V vs. 88 V for normal HEMT) and electrical stability (\u223c0.3% electric field stress induced drain current degradation versus \u223c6% for normal HEMT after 25 V drain bias). The drastic improvement in device performance stability, renders the new process highly promising for GaN based, microwave power amplifier applications in communication and radar systems. Keywords AlGaN/GaN MOSHEMT Ni/Ti Breakdown voltage Stability 1 Introduction AlGaN/GaN HEMT is expected to be widely applied in high power and high frequency area due to its outstanding properties, for instance, high density (\u223c10 13 cm \u22122 ) of two-dimensional electron gas ( 2DEG ), higher mobility and saturated electron velocity, wider energy band gap (3.39 eV). Schottky-contact gates are commonly used in AlGaN/GaN HEMTs, because native oxide is unavailable. Thus, the power handling capability of these transistors is often constrained by the high gate leakage current, and low drain breakdown voltage. MOSHEMT with insulators, such as SiN x , SiO 2 , and Al 2 O 3 , obtained through CVD s, were applied to take place of the Schottky-contact gates. Improved transistor power performance has been repeatedly demonstrated through the adoption of insulating gate in an AlGaN/GaN MOSHEMT. Additional techniques such as field plates [1] , special recessed gates [2] have also been applied to achieve improved transistor\u2019s stability, higher breakdown voltage. However, additional processing steps or complexity could lead to processing yield reduction. Simple wafer techniques for high power GaN Schottky-gate HEMT fabrication are urgently needed. In this article, a very simple, novel method was proposed to fabricate gate insulator, which was shown to enhance the performance of AlGaN/GaN HEMTs. In our experiments, the gate insulator was formed by direct thermal oxidation of composite Ni/Ti films. Ti could be thermal oxidized as TiO 2 at a temperature above 400 \u00b0C [3] . Furthermore, a thicker gate insulator layer could be used due to a very high relative dielectric constant ( \u03b5 r ) of TiO 2 , which could make the leakage current much lower for a specific gate capacitance. Moreover, TiO 2 would lead to very high breakdown voltage for AlGaN/GaN HEMTs, even more than 2000 V [4] . Unfortunately, Ti is not suitable to be put in direct contact with AlGaN/GaN because Ti will react with AlGaN/GaN at high temperature [5] and cause larger leakage current. We use a very thin Ni to prevent the reaction between Ti and AlGaN/GaN. It is known that Ni is also easy to be thermal oxidized as gate insulator in practice [6] . 2 Device fabrication and measurements The cross-sectional figure of AlGaN/GaN MOSHEMT was shown in Fig. 1 . The devices were prepared on an Al 0.28 Ga 0.72 N/GaN wafer with a 2DEG sheet density of 6.3 \u00d7 10 12 cm \u22122 and Hall mobility of 950 cm 2 /V S. At the beginning, the wafer was cleaned ultrasonically with acetone, ethanol and de-ionized water for 5 min respectively. Then the sample was etched with Cl 2 -based Inductive Coupling Plasma ( ICP ) to fabricate isolation mesa with thickness about 1350 \u00c5. Subsequently, Ohmic contacts of Ti/Al/Ni/Au (200/1300/500/2000 \u00c5) were prepared with traditional lift-off technique and rapid thermal annealing ( RTA ) in a N 2 atmosphere, where the annealing temperature and time were 900 \u00b0C and 30 s respectively. Then Ni/Ti (40/220 \u00c5), were deposited onto the substrate with electron beam evaporator ( EBE ) at a background pressure of 2.2 \u00d7 10 \u22124 Pa. Then it was oxidized at 500 \u00b0C for 30 min in pure O 2 with a flow rate of 2.5 l/min. After the oxidation, the wafer became totally transparent, indicating that the metals had been fully transformed into oxides. After the gate metals, Ni/Au (500/1000 \u00c5), were deposited, the fabrication of MOSHEMTs were completed. The size of the devices was as follows: the gate length ( L G ) was 3.5 \u03bcm, the width of the gate ( W G ) was 80 \u03bcm, the distance between gate and drain edge ( L GD ) was 3 \u03bcm and the distance between gate and source edge ( L GS ) was 1 \u03bcm. Besides the devices, MOS diode was form on the same wafer. Their top view of the target shaped MOS diode is shown in the inset of Fig. 3 . The circle in the center was normal Ni/Au (500/1000 \u00c5) metal, with a radius of 40 \u03bcm. The circular ring was Ohmic contact metal with radiuses of 60 and 130 \u03bcm. The oxide of Ni/Ti was under Ni/Au and within the Ohmic ring. Without fabricating of the oxide, Schottky testing units with the same top view were prepared. With almost the same processing flows, except for the fabrication of insulator, a normal HEMT with identical geometry was also prepared. The normal HEMT featured a Ni/Au Schottky-gate metal. After the devices and the testing structures were completed, a series of tests were employed to show the oxide and the devices\u2019 performance. The cross-sectional morphology and selected area electron diffraction (SAED) of the insulator were measured with FEI TECNAI G 2 high resolution transmission electron microscopy (HRTEM). The C \u2013 V curves of both MOS and Schottky diode structures were measured with HP4192A LF Impedance Analyzer . MOSHEMT and Schottky-gate HEMT\u2019s breakdown voltage at off state were measured with a high-voltage testing system. The high-voltage was supplied by QT 2 Transistor Characteristics Curve Tracer and the gate voltage was supplied by JWY - 30C DC power supply. Both devices\u2019 gate leakage current and transfer characteristic curves were measured with HP 4156C Parameter Analyzer. We measured the output characteristics of Schottky-gate HEMT and MOSHEMT with HP 4156C Parameter Analyzer . We also measured DC stress ( V DS = 20 V, V GS = 0 V, time = 30 s) induced current collapse for both devices. The DC stress was applied for two cycles. The degradation of transient current immediately after high electronic field DC bias drain stress was also used to evaluate the device\u2019s stability [7] . In addition, the transient current ( V DS = 5 V, V GS = 0 V) of both devices before and after five rounds of stress ( V DS = 25 V, V GS = 0 V, time = 30 s) were measured. 3 Results and discussion 3.1 Characteristics of the oxide The cross-sectional figure of the insulators was shown in Fig. 2 . Apparently, the insulator consists of two layers, indicating that Ti and Ni were oxidized separately during the thermal oxidation. The circular SAED patterns indicated that both kinds of oxides were polycrystalline. According to our former experiments, Ti films would totally transfer into rutile when the temperature was higher than 500 \u00b0C [8] . Therefore, the upper insulator should be rutile-TiO 2 . The crystalline lattice of AlGaN near the interface between AlGaN and insulator was observed to be perfect, indicating no damage caused by the processes. Moreover, a periodic crystalline lattice of NiO indicates that Ni was totally transformed into oxide. The thickness of the oxide could be estimated by assuming that oxides would have the same amounts of substance and areas with their native metals after the oxidization. According to their amounts of substance and atomic volume, the thickness of rutile-TiO 2 and NiO was calculated to be 393 and 68 \u00c5 respectively. The actual thickness of TiO 2 and NiO measure in TEM was about 370 and 60 \u00c5. C \u2013 V tests were employed to study further about the novel oxide layer\u2019s characteristics. In Fig. 3 , the C \u2013 V curves of both Schottky diode and MOS structures were shown. The top view of the testing structures was attached in the inset. The capacitance ( V = 0 V) of Schottky and MOS structure @1 MHz was 16.2 PF and 14.2 PF respectively. Such large a MOS capacitance was contributed mainly by the high relative dielectric constant of TiO 2 . MOS structure\u2019s gate capacitance is close to the Schottky diode, implying that this novel gate oxide will not reduce HEMT\u2019s transconductance greatly. Sheet density of 2DEG of Schottky and MOS testing structure calculated from the C \u2013 V curves is 6.21 \u00d7 10 12 and 6.72 \u00d7 10 12 cm \u22122 respectively. The 8% increasing of 2DEG density is suspected to be caused by strain associated with the insulating oxide layer on AlGaN/GaN heterostructure. 3.2 Novel MOS structure induced enhancement in devices\u2019 performance The gate leakage current of Schottky-gate HEMT and MOSHEMT were shown in Fig. 4 . During the measurement, both drain and source electrodes were grounded and a varying voltage was applied to the gate electrode. The leakage current of MOSHEMT was reduced by three orders of magnitude. Fig. 5 showed the transfer characteristics of Schottky-gate HEMT and MOSHEMT. Maximum transconductance, g m , of Schottky-gate HEMT and MOSHEMT is 77.2 and 72.5 mS/mm respectively. MOSHEMT also showed a wider full width of half maximum (FWHM) than normal HEMT, indicating a potentially wider linear operating range when it is used as an amplifier. Both devices\u2019 breakdown voltage ( V br ), at pinch-off state (with gate voltage of \u22125 V) was measured and shown in Fig. 6 . MOSHEMT has an average 471 V breakdown voltage, which is 5.35 times of the Schottky-gate HEMT. The 5-times increase in V br , coupled with a comparable g m , indicates MOSHEMT with novel gate oxide layer should greatly enhance power handling capability than the Schottky-gate HEMT. The study on the mechanism of high breakdown voltage of the MOSHEMT will be performed in next research work. 3.3 Drain bias voltage and time dependence of device behavior Output characteristics of Schottky-gate HEMT and MOSHEMT were shown in Fig. 7 . MOSHEMT shows more uniform saturated I DS changing vs. V GS , which shows its better linearity of power amplification. A double-cycle DC stress ( V DS = 20 V, V GS = 0 V, time = 30 s) induced current collapse for both devices were also shown in Fig. 7 . It is shown that the DC stress resulted in an apparent degradation in output currents of HEMT, but little change in that of MOSHEMT. Thus, it is believed that the gate insulator by oxidation of Ni/Ti should improve the performance stability of AlGaN/GaN MOSHEMT. MOSHEMT also showed an improved stability in drain current transient characteristics. In Fig. 8 , transient currents before and after a 5-round DC stress ( V DS = 25 V, V GS = 0 V, time = 30 s) for both devices were shown, where I d 0 stands for the virgin transient current and I dx stands for the transient current after the X round of stress. All the current data of both devices were normalized with respect to their initial value measured at 40 s, which was the final value in the transient characteristics. MOSHEMT showed excellent capability of suppressing the high electric stress induced drain current degradation. Only about 0.3% current reduction after the first round of stress ( I d1 ) was observed. While the reduction of transient drain current of Schottky-gate HEMT was found to be about 5.85%, which is about 19 times larger than MOSHEMT. 4 Conclusion A novel and easy technique of oxidation of composite titanium\u2013nickel as gate dielectric in AlGaN/GaN MOSHEMT was proposed. In comparison with normal Schottky-gate GaN HEMT, devices with such a gate oxide exhibited much better performances with the drain breakdown voltage increased by more than five times and the gate leakage current reduced by three orders of magnitude. Moreover, the stress induced transient current degradation of MOSHEMT with composite titanium\u2013nickel oxide gate insulator was found to be 20 times smaller than normal HEMT with Schottky-gate. All the results show that MOSHEMT with this novel and simple processing is hopeful for high power microwave power amplifier applications.

The surface oxide and decomposed layers could be effectively removed and a perfect AlGaN surface is obtained after the treatment. Pulsed IV and RF power measurement indicate that the current collapse is greatly suppressed due to the removing of imperfect surface layer and damage free nature, providing an effective surface treatment method to improve the effect of passivation in GaN HEMT.",

Normally off operation is obtained by multiple cycles of O2 plasma oxidation and wet oxide-removal gate recess process. The recessed normally off GaN MOSFET with 3 \u03bcm gate-drain distance exhibits a maximum drain current of 585 mA/mm at 9 V gate bias. The threshold voltage of the MOSFET is 2.8 V with a standard derivation of 0.2 V on the sample with an area of 2 \u00d7 2 cm2. The gate leakage current is below 10-6 mA/mm during the whole gate swing up to 9 V and the ION/IOFF ratio is larger than 109, indicating the good quality of Al2O3 gate insulator. The MOSFET with 10 \u03bcm gate-drain distance shows a three terminal OFF-state breakdown voltage (BV) of 967 V at zero gate-source bias with a drain leakage current criterion of 1 \u03bcA/mm. The specific ON-resistance (RON,SP) of the device is 1.6 mQ \u00b7 cm2 and the power figure of merit (BV2/RON,SP) is 584 MW/cm2.",

        "abstract": "In this letter, we investigated the behaviors of surface-and buffer-induced current collapse in AlGaN/GaN high-electron mobility transistors (HEMTs) using a soft-switched pulsed I-V measurement with different quiescent bias points. It is found that the surface-and buffer-related current collapse have different relationship with the gate and drain biases (V-GS0, V-DS0) during quiescent bias stress. The surface-induced current collapse in devices without passivation monotonically increases with the negative V-GS0, suggesting that an electron injection to the surface from gate leakage is the dominant mechanism and the Si3N4 passivation could effectively eliminate such current collapse. The buffer-induced current collapse in devices with intentionally carbon-doped buffer layer exhibits a different relationship with V-GS0 after surface passivation. The buffer-related current collapse shows a bell-shaped behavior with V-GS0, suggesting that a hot electron trapping in the buffer is the dominant mechanism. The soft-switched pulsed I-V measurement provides an effective method to distinguish between the surface-and buffer-related current collapse in group III-nitride HEMTs.",

After the illumination of the heterostructures, the total two-dimensional\n electron gas concentration increases, and the SdH oscillation amplitudes are enhanced when there is no additional subband\n occupation. It is also found that the energy separation between the subbands decreases after the illumination. We suggest\n that the illumination decreases the electric field and thus weakens the quantum confinement of the triangular quantum well\n at Al\n x\n Ga1\u2212x\n N/GaN heterointerfaces.

The zero-field spin splitting effect is observed by excluding the magnetointersubband scattering effect. The obtained zero-field spin splitting energy is 2.5 meV, and the obtained spin-orbit coupling parameter is 2.2\u00d7 10-12 eV m. Despite the strong polarization-induced electric field in the heterostructures, the spin-orbit coupling parameter in Alx Ga1-x NGaN heterostructures is smaller than that in other heterostructures, such as Inx Ga1-x As Iny Al1-y As ones. This is due to the large effective mass of the two-dimensional electron gas and the large GaN energy band gap in Alx Ga1-x NGaN heterostructures. With an increase in magnetic field, the spin splitting energy becomes smaller. The zero-field effect is still the dominant mechanism in Alx Ga1-x NGaN heterostructures at a magnetic field as high as 4.4 T. \u00a9 2006 American Institute of Physics.",

A small but significant decrease of the Hall slope with the increase of temperature was discovered. This is not due to the increase of electron concentration as temperature increases but to the EEI effect. Both diffusion and ballistic contributions of EEI to the conductivity of 2DEG were observed. As the temperature increases, the negative diffusion EEI correction to the conductivity increases in an absolute value while the ballistic EEI correction reduces to a renormalization of the transport mobility. \u00a9 2011 Elsevier Ltd.

        "abstract": "Two-dimensional transition medal dichalcogenides (TMDCs) possess the K (K') valley degree of freedom (DOF). Based on that, the research on valleytronics draws considerable attention. In this report, by breaking the spatial inversion symmetry by an out-of-plane electric field, the valley Hall effect (VHE) is observed in multilayer Tungsten Diselenide (WSe2) at room temperature. The none-zero Berry curvature emerges, leading to the carriers at K (K') valley be deflected to the opposite sides of the channel, giving rise to a spatial polarization of carriers at K (K') valleys in multilayer WSe2. This observation of the VHE illustrates that the K (K') valley DOF can be generated in multilayer WSe2, which makes it alternative candidate for valleytronics.",

The change of magnetoresistance from positive to negative under a perpendicular low magnetic field indicates that electron spin-orbit scattering caused by crystal field exists in Al0.22 Ga0.78 N/GaN heterojunction. The relation between the spin-orbit scattering time and the temperature is discussed for 2DEG, the inelastic scattering time measured by experiment shows a strong temperature dependence according to T-1 rule, which indicates that the electron-electron scattering with small energy transfer is the dominant inelastic process.",

Below the threshold, the linear-polarized stimulated emission has been the dominating part of overall emission and closely related to resonant cavity.

Moreover, the separation of quasi-Fermi levels of electrons and holes across the active region has already exceeded the photon emission energy, namely, realized the population-inversion.",

The Rashba spin-orbit coupling constant \u03b1 deduced using the weak antilocalization analysis showed a good agreement with that estimated from the analysis of the beating patterns for the sample before and after illumination.

The observed photocurrent consists of the superposition of the CPGE and the linear photogalvanic effect currents, both of which are up to 10-2 nA. The amplitude of the CPGE current increases linearly with additional strain and is enhanced by 18.6% with a strain of 2.2\u00d7 10-3.

From the temperature dependence of the longitudinal conductivity of the heterostructures, a clear transition region has been observed. Based on the theoretical analysis, we conclude that this region corresponds to the transition from the diffusive regime to the ballistic regime of the 2DEG transport property. The interaction constant is determined to be -0.423, which is consistent with the theoretical prediction. However, the critical temperature for the transition, which is 8 K in AlxGa1-xN/GaN heterostructures, is much higher than the theoretical prediction. \u00a9 2007 Elsevier B.V. All rights reserved.",

When the well width is chosen to be 1.91 nm, the three-energy-level DQWs are realized. The ISBT between the first odd order and the second even order subbands (the 1odd - 2even ISBT) has comparable absorption coefficient with the 1odd - 2odd ISBT. Their wavelengths are located at 1.3 and 1.54 \u03bcm, respectively. When the well width is 2.77 nm, the four-energy-level DQWs are realized. The 1odd - 2even and the 1even - 2odd ISBTs have comparable absorption coefficients. Their wavelengths are located at 1.41 and 2.54 \u03bcm, respectively. The energy separation between the excited subbands is determined to have the minimum value of 144 meV due to the band anticrossing interaction. The calculated results give possible application to ultrafast two-color optoelectronic devices operating within the optical communication wavelength range. \u00a9 2007 American Institute of Physics.",

It is found that the spin splitting energy becomes smaller with an increase in magnetic field, indicating that the Zeeman spin splitting is not dominant at measured magnetic field range. Within this magnetic field range, the zero-field spin splitting, as well as Zeeman spin splitting, affects the split peaks in the oscillatory magnetoresistance of the 2DEG in Alx Ga1-x NGaN heterostructures. \u00a9 2006 American Institute of Physics.",

Magnetoresistance of a two-dimensional electron gas confined in the heterostructure is investigated. The negative magnetoresistivity in the whole magnetic field range originates from the electron-electron interactions (EEIs), while the positive magnetoresistivity in the high field range results from the parallel conductance. The EEI correction terms, as well as the concentration and mobility of the parallel channel are obtained by fitting the experimental data.

The result show that residual stress in GaN films is relaxed by generating edge-type threading dislocations (TDs) instead of screw-type TDs. Compared to as-grown GaN films, the annealed ones have larger mean twist angles corresponding to higher density of edge-type TDs but smaller mean tilt angles corresponding to lower density of screw-type TDs films. Due to the increased edge-type TD density, the lateral coherence lengths of the annealed GaN films also decrease. The results obtained from chemical etching experiment and grazing-incidence x-ray diffraction (GIXRD) also support the proposed structure evolution. \u00a9 2006 Chinese Physical Society and IOP Publishing Ltd.",

Two-dimensional electron systems (2DESs) offer a particularly important SOC platform, where spin polarization can be tuned with an electric field perpendicular to the 2DES. Here, by measuring the tunable circular photogalvanic effect (CPGE), we present a room-temperature electric-field-modulated spin splitting of surface electrons on InN epitaxial thin films that is a good candidate to realize spin injection. The surface band bending and resulting CPGE current are successfully modulated by ionic liquid gating within an electric double-layer transistor configuration. The clear gate voltage dependence of CPGE current indicates that the spin splitting of the surface electron accumulation layer is effectively tuned, providing a way to modulate the injected spin polarization in potential spintronic devices.",

Effective-mass values of the two-dimensional electron gas (2DEG) in the triangular quantum well at the heterointerfaces are obtained by analyzing the temperature-dependent Shubnikov-de Haas oscillations. It is found that the values have strong dependence on the magnetic field and the 2DEG density. Our results show that the effective mass increases 0.01 m0 T and 0.0027 m0 electron density of 1012 cm-2. Such behavior is thought to be due to the conduction band nonparabolicity in GaN. The extrapolated band edge effective mass of m0* = (0.145\u00b10.006) m0 is obtained, which is smaller than most reports that neglected the influence of the magnetic field in Alx Ga1-x NGaN heterostructures. \u00a9 2006 American Institute of Physics.",

The AHE current changes linearly with the varied longitudinal electric fields. Due to the strong Rashba spin-orbit coupling of the two-dimensional electron gas in Al0.25 Ga0.75 N/GaN heterostructures, the intrinsic anomalous Hall mechanism is supposed to contribute to the photoinduced AHE. The photoinduced AHE measurement proposed in this study could be used to other spin related measurements at room temperature. \u00a9 2011 American Institute of Physics.",

It is observed that the energy separation between the two subbands decreases due to the weakened electric field at the Alx Ga1-x NGaN heterointerfaces after the illumination. Meanwhile, the beating nodes induced by the MIS effect shift to higher magnetic field due to the increase of the 2DEG concentration at the second subband, and the beating nodes induced by the zero-field spin-splitting effect shift to lower magnetic field due to the decrease of the spin-splitting energy of the 2DEG. Since the weakened electric field decreases the zero-field spin-splitting energy, it is suggested that the zero-field spin splitting of the 2DEG in Alx Ga1-x NGaN heterostructures mainly arises from the Rashba effect. \u00a9 2007 The American Physical Society.",

This quasi-2D InGaN layer was successfully achieved by molecular beam epitaxy (MBE), and an excellent in-plane uniformity in this layer was confirmed by cathodoluminescence mapping study. The carrier dynamics have also been investigated by time-resolved and excitation-power-dependent photoluminescence, proving that the recombination occurs via confined excitons within the ultrathin quasi-2D InGaN layer even at high temperature up to ~220\u2009K due to the enhanced exciton binding energy. This work indicates that such structure affords an interesting opportunity for developing high-performance photonic devices.",

        "abstract": "Intense emission from an InGaN quantum disc (QDisc) embedded in a GaN nanowire p-n junction is directly resolved by performing cathodoluminescence spectroscopy. The luminescence observed from the p-type GaN region is exclusively dominated by the emission at 380 nm, which has been usually reported as the emission from Mg induced impurity bands. Here, we confirm that the robust emission from 380 nm is actually not due to the Mg induced impurity bands, but rather due to being the recombination between electrons in the QDisc and holes in the p-type GaN. This identification helps to get a better understanding of the confused luminescence from nanowires with thin QDiscs embedded for fabricating electrically driven single photon emitters.",

        "abstract": "Due to the intrinsic spontaneous and piezoelectric polarization effect, III-nitride semiconductor heterostructures are promising candidates for generating 2D electron gas (2DEG) system. Among III-nitrides, InN is predicted to be the best conductive-channel material because its electrons have the smallest effective mass and it exhibits large band offsets at the heterointerface of GaN/InN or AlN/InN. Until now, that prediction has remained theoretical, due to a giant gap between the optimal growth windows of InN and GaN, and the difficult epitaxial growth of InN in general. The experimental realization of 2DEG at an InGaN/InN heterointerface grown by molecular beam epitaxy is reported here. The directly probed electron mobility and the sheet electron density of the InGaN/InN heterostructure are determined by Hall-effect measurements at room temperature to be 2.29 \u00d7 10 cm V s and 2.14 \u00d7 10 cm, respectively, including contribution from the InN bottom layer. The Shubnikov-de Haas results at 3 K confirm that the 2DEG has an electron density of 3.30 \u00d7 10 cm and a quantum mobility of 1.48 \u00d7 10 cm V s. The experimental observations of 2DEG at the InGaN/InN heterointerface have paved the way for fabricating higher-speed transistors based on an InN channel.",

A strain-free Raman frequency and a biaxial stress coefficient for E 2 (high) mode are experimentally determined to be 657.8\u00a0\u00b1\u00a00.3\u00a0cm \u22121  and 2.4\u00a0\u00b1\u00a00.2\u00a0    c   m   \u2212  1    /  G  P  a    , respectively. By using these parameters, the residual stress of a series of AlN layers grown under different buffer layer conditions has been investigated. The residual compressive stress is found to be obviously decreased by increasing the Al/N beam flux ratio of the buffer layer, indicating the generation of tensile stress due to stronger coalescence of AlN grains, as also confirmed by the  in-situ  reflection high energy electron diffraction (RHEED) monitoring observation. The stronger coalescence does lead to improved quality of AlN films as expected.",

More importantly, the better crystalline quality leads to a positive photovoltaic efficiency temperature coefficient up to 423\u2009K, which shows the property and advantage of wide gap semiconductors like InGaN, signifying the potential of III-nitride based solar cells for high temperature and concentrating solar power applications.",

A negative PC has been observed in InN and high In-composition InxGa1-xN, whereas the PC gradually changed to be positive with decreasing x. Transition from negative to positive PC occurred at In-composition of ~0.7. An energy band model is proposed to explain the experimental observation, in which the negative PC is mainly due to that the recombination centers capture the mobile holes and become positively charged. Those positively charged centers then scatter the electrons, decrease their mobility and consequently reduce the conductivity. With decreasing In composition, the recombination centers probably become less and less, leading to a normally positive PC.",

We report in this paper a novel way to probe the doping type in GaN NWs by photoassisted kelvin probe force microscopy (KPFM), as a proper example showing that this approach is straight forward, effective and practical. Through illumination with super-bandgap light, photo-generated electrons in the n-region are swept away from the surface due to the electric field in the space-charge region, thus the holes move to the surface; while in contrast, electrons in the p-region will move to the surface. The fact that the quasi-Fermi level moves upwards in n-type while downwards in p-type identifies the doping type of GaN NWs, and is clearly revealed by the contact potential difference detected by photoassisted KPFM.",

Upon above bandgap light illumination in the ambient atmosphere, the surface photovoltage of the In-polar InN shows a pronounced decrease, while that of the N-polar one keeps almost constant. Those different behaviors between N-polar and In-polar surfaces are attributed to a polarity-related surface reactivity, which is found not to be influenced by Mg-doping. These findings provide a simple and non-destructive approach to determine the lattice polarity and allow us to suggest that the In-polar InN, especially that with buried p-type conduction, should be chosen for sensing application.",

        "abstract": "High-electron-mobility InN epilayers are achieved under the extremely In-rich condition on Si (111) substrates by molecular beam epitaxy. A directly probed electron mobility of 3640\u2009cm2\u2009V\u22121\u2009s\u22121 and a residual electron concentration of 2.96\u2009\u00d7\u20091017\u2009cm\u22123 are detected by Hall-effect measurements at room temperature, which corresponds to a remarkable mobility of 3970\u2009cm2\u2009V\u22121\u2009s\u22121 and an electron concentration of 2.45\u2009\u00d7\u20091017\u2009cm\u22123 in the InN bulk layer taking into account the electron accumulation layers with a density of 5.83\u2009 \u00d7\u20091013\u2009cm\u22122 and a mobility of 429\u2009cm2/V s. It is found that extremely the In-rich growth condition is most likely favorable to suppress impurity incorporation and weaken the dislocation scattering due to low proportionally charged dislocations, hence leading to high electron mobility.",

Transition of dominant lattice sites of Mg dopants was investigated through a diffusion-collision model based on Mg-related local vibrational modes, which was further confirmed through stress analysis. It was found that Mg i  and Mg In -N-In i  are the dominant sites of Mg dopants at [Mg]\u202f 20 \u202fcm \u22123 , while the complex of Mg In -N-Mg i  dominates with further increasing [Mg]. This study provides an insight on the behavior of Mg and would be helpful for achieving effective p-type doping in InN.",

This quasi-2D InGaN layer was successfully achieved by molecular beam epitaxy (MBE), and an excellent in-plane uniformity in this layer was confirmed by cathodoluminescence mapping study. The carrier dynamics have also been investigated by time-resolved and excitation-power-dependent photoluminescence, proving that the recombination occurs via confined excitons within the ultrathin quasi-2D InGaN layer even at high temperature up to ~220\u2009K due to the enhanced exciton binding energy. This work indicates that such structure affords an interesting opportunity for developing high-performance photonic devices.",

        "abstract": "Intense emission from an InGaN quantum disc (QDisc) embedded in a GaN nanowire p-n junction is directly resolved by performing cathodoluminescence spectroscopy. The luminescence observed from the p-type GaN region is exclusively dominated by the emission at 380 nm, which has been usually reported as the emission from Mg induced impurity bands. Here, we confirm that the robust emission from 380 nm is actually not due to the Mg induced impurity bands, but rather due to being the recombination between electrons in the QDisc and holes in the p-type GaN. This identification helps to get a better understanding of the confused luminescence from nanowires with thin QDiscs embedded for fabricating electrically driven single photon emitters.",

Distinctly different trends in surface photovoltage are observed for Ga-rich alloys compared with In-rich alloys, which is explained in terms of the direction of surface band bending. With the determination of the Fermi energy level at the surface and in the bulk, the results reveal that for an In x Ga1\u2212 x N alloy, the transition from a surface electron accumulation layer for In-rich alloys to a surface electron depletion layer for Ga-rich alloys occurs at x \u2248 0.63.",

        "abstract": "Modulating lasing wavelength flexibly and repeatedly on a single rod is essential to the practical applications of micro/nanorod lasers. In this paper, a structure that decouples the gain medium and optical cavity is proposed, where the corresponding mechanism for the lasing wavelength shift is explained. Based on the above structure, one kind of wavelength continuously variable lasers is achieved on a single GaN/InGaN core\u2013shell microrod without modifying the geometry of the resonant cavity or cutting the microrod. By using this method, lasing wavelength can be modulated from 372 to 408 nm flexibly and repeatedly in a 10 \u03bcm facilely synthesized microrod. This approach demonstrates a big application potential in numerous fields consisting of optical telecommunication and environmental monitoring.",

Here, we report studies on the nanoscale fissures related surface instability in AlGaN/GaN heterostructures. Experimental results reveal that edge dislocations are actually the root cause of the surface instability. The nanoscale fissures are initially triggered by the edge dislocations, and the subsequent evolution is associated with tensile lattice-mismatch stress and hydrogen etching. Our findings resolve a long-standing problem on the surface instability in AlGaN/GaN heterostructures and will also lead to new understandings of surface growth kinetics in other hexagonal semiconductor systems.",

The methodology is based on a combination of lateral and vertical electrical stress measurements employing three ohmic terminals on the test sample structure with different GaN buffer designs. By monitoring the evolution of the lateral current during lateral as well as vertical stress application, we investigate the trapping/detrapping behaviors of the hot electrons and identify that the traps correlated with current degradation are in fact located in the GaN buffer layers. The trap activation energies (0.38\u20130.39\u2009eV and 0.57\u20130.59\u2009eV) extracted from either lateral or vertical stress measurements are in good agreement with each other, also confirming the identification. By further comparing the trapping behaviors in two samples with different growth conditions of an unintentionally doped GaN layer, we conclude ...",

The two dimensional electron gas (2DEG) mobility is 2200\u00a0cm 2 /Vs with an electron density of 7.3\u00a0\u00d7\u00a010 12 \u00a0cm \u22122 .

The achievement is attributed to the fact that this method can significantly remove the Al, Ga, etc. metal droplets coating on the post growth flow flange and reactor wall which are difficult to clean by normal bake process under H 2  ambient.",

It is found that the thicker the barrier, the longer the luminescence lifetime. As the barrier becomes thick, the quantum confinement of the triangular quantum well increases. It is believed the space wave function overlap between the better confined electrons and spreaded holes is fewer in thicker barrier sample, which results in a longer 2DEG PL lifetime.",

By depositing the AlN spacer layer at a low temperature after the growth interruption, the surface morphology and interface quality have been significantly improved. Electron mobilities of 1620\u2009cm2/Vs at room temperature and 8260\u2009cm2/Vs at 77\u2009K are achieved while delivering a high electron sheet density of about 2.0\u2009\u00d7\u20091013\u2009cm\u22122, resulting in an extremely low sheet resistance of 186 \u03a9/\u25a1 at room temperature and 37 \u03a9/\u25a1 at 77\u2009K. The experimental results evidence that it is the high interface quality that contributes to the improvement of electron transport properties. Our results provide an effective approach to obtain high quality InAlGaN/GaN heterostructures.",

A qualitative model is proposed to explain the relaxation process. It is revealed that the anisotropic misfit strain is quickly relaxed in the low temperature AlN layer by the formation of interface misfit dislocations, small misoriented grains, and lattice distortion. As a result, isotropic properties and atomically smooth surface are observed in the high temperature AlN layer. Based on this isotropic AlN layer, a high quality GaN layer and AlGaN/GaN heterostructures with a high electron mobility of 2160\u2009cm2/(V\u2009 \u00b7\u2009s) have been obtained. This work will have important impacts on the understanding of the epitaxy of isotropic semiconductor films on anisotropic substrates.",

The extent of the current degradation is determined by back-gating sweep measurements in double directions at different sweep rates and temperatures. It is found that the current degradation is only observed at relatively slow sweep rates and high temperatures. Time dependent back-gating measurements further suggest that the current degradation process is related to traps with long time constants. By comparing with the measurement results of samples on sapphire substrates, we confirm that the current degradation is caused by vertical leakage in heterostructures on Si. On the basis of the vertical leakage induced current degradation mechanism and in conjunction with the long-time degradation process, we measure both the trapping and detrapping processes of the relevant trap states to identify their properties. We find that there is a 0....",

        "abstract": "Abstract   We present a hot electron assisted vertical leakage/breakdown mechanism in AlGaN/GaN heterostructures on Si substrates by a combination of applying vertical and lateral bias conditions. Beyond a critical bias point, the vertical leakage current under the combined bias condition is larger than that under a pure vertical bias condition which results in a lower breakdown voltage. The critical bias has a positive temperature dependence. A model is proposed that highly energetic hot electrons can release trapped electrons from defects and even ionize them. The model is proved by investigating the detrapping and ionization mechanisms by changing hot electron energy.",

The trapping mechanism is characterized by measuring C-V dispersion after three different configurations of bias stress: high drain-substrate voltage stress, high drain-gate voltage stress and combined stress (with both high drain-gate voltage and drain-substrate voltage stress). Under the combined stress, the 2DEG degradation is the overall effect of electron trapping and hole trapping. By comparing samples with and without the UID GaN layer, we confirm the role of the UID layer in suppressing the 2DEG degradation by hole trapping in that layer. The electron and hole trap states are further identified by reversed vertical stress and current transient measurements. The electron trap with an activation energy of 0.53 eV and the hole trap with an activation energy of 0.81 eV are distinguished.",

At high electric field, the AlN interlayer as an energy barrier can suppress the injection of electrons from the silicon substrate into the top buffer layers, and eventually a vertical leakage was reduced by two orders of magnitude at 600\u202f\u202fV.

        "title": "Free and bound excitonic effects in Al0.5Ga0.5N/Al0.35Ga0.65N MQWs with different Si-doping levels in the well layers",
        "abstract": "Free exciton (FX) and bound exciton (BX) in Al0.5Ga0.5N/Al0.35Ga0.65N multiple quantum wells (MQWs) with different Si-doping levels in the well layers are investigated by photoluminescence (PL) spectra. Low temperature (10\u2009K) PL spectra identify a large binding energy of 87.4\u2009meV for the BX in undoped sample, and 63.6\u2009meV for the BX in Si-doped (2\u2009\u00d7\u20091018\u2009cm\u22123) sample. They are attributed to O-bound and Si-bound excitons, respectively. The large binding energies of BX are assumed to originate from the strong quantum confinement in the quantum wells, which also leads to a stronger FX PL peak intensity in comparison with BX at 10\u2009K. Si-doping is found to suppress the FX quenching by reducing threading dislocation density (TDD) in the well layers, leading to a significant improvement of IQE from 33.7% to 45%. In the past decade, AlGaN-based deep ultraviolet light-emitting diodes (DUV-LEDs) have attracted considerable attentions owing to their wide application potentials in biomedical and analytical instrumentation, sterilization and decontamination, UV curing, and high density optical recording1, 2. Compared with conventional mercury vapor lamps, AlGaN-based solid-state UV sources have significant advantages in terms of size, operation voltage, spectral tunability, and being environmentally friendly. Impressive research efforts have achieved luminescence from 210\u2009nm to 365\u2009nm over the range of full Al compositions1, 2, 3, 4. Despite these tremendous opportunities and progress, DUV-LEDs still suffer from relatively low external quantum efficiencies (EQEs) as well as output light power, in comparison with commercial blue LEDs. The EQEs of DUV-LEDs with wavelength shorter than 280\u2009nm are less than 11% in previous reports1, 2, 4, 5. As a result, the output power of DUV-LEDs with corresponding wavelength is still under 100\u2009mW up to date1, 2, 6. IQE is the key factor determining the performance of DUV-LEDs. It is known that higher IQE can be achieved by using a better underlying epilayer having low TDD7. The IQE can also be improved through optimization of the MQWs structures8, 9, 10. A detailed knowledge of the exciton behavior in high-Al-content AlGaN/AlGaN MQWs would certainly provide useful guidance for MQWs structure improvement. Along that direction, exciton behavior in GaN bulk has been investigated by many groups. The binding energy of FX, donor-bound exciton (DX), and acceptor-bound exciton (AX) in GaN has been reported in large volumes11, 12, 13. The radiative recombination lifetime of FX and BX in GaN ranges from 125\u2009ps to 530\u2009ps13, 14. For bulk AlN, the binding energy of FX has also been reported, ranging from 47\u2009meV to 80\u2009meV15, 16, 17. As for AlGaN/GaN and InGaN/GaN MQWs, multiple factors which affect the FX and BX binding energy have been studied by theoretical calculations18, 19. With regard to high-Al-content AlGaN bulk and AlGaN/AlGaN MQWs, many reports focus on the exciton localization behavior and optical polarization properties, while few reports pay attention to the relevant parameters of FX and BX. In this study, we investigated the FX and BX behavior of high-Al-content AlGaN/AlGaN MQWs with different Si-doping levels in the well layers. Three MQWs samples (sample-A, -B, and -C) were prepared, whose structures are shown in Fig. 1. The active region consists of five 2.5-nm-thick Al0.35Ga0.65N well layers separated by 10-nm-thick Al0.5Ga0.5N barrier layers. The only difference among sample-A, -B, and -C lies in the Si-doping concentration of the well layers, being 0, 5\u2009\u00d7\u20091017, and 2\u2009\u00d7\u20091018\u2009cm\u22123, respectively. A collection of near-band-edge time-integrated PL spectra at 10 K is presented in Fig. 2 (a). It shows that two distinct peaks at 275.40\u2009nm and 280.85\u2009nm appear in the spectrum of sample-A. Similarly, two peaks at 276.72\u2009nm and 280.70\u2009nm are observed from the spectrum of sample-C. It is clear that the peak spacing between the FX and BX peak is different for sample-A and -C. We attribute the two peaks in either sample-A or sample-C to FX and BX luminescence from Al0.5Ga0.5N/Al0.35Ga0.65N MQWs. The energy spacing between the FX and BX peak represents the binding energy of a \u201ccertain impurity or defect\u201d-bound exciton. Two BX binding energies of 87.4 (for sample-A) and 63.6\u2009meV (for sample-C) can then be derived from the PL spectra. While for sample-B, besides the FX peak at 276.46\u2009nm, there are two identifiable BX peaks on the long-wavelength side, whose corresponding binding energies are 89.1 and 63.6\u2009meV, respectively. The binding energy difference for BX in undoped sample-A and Si-doped sample-C is attributed to the fact that the excitons are bound to different impurity atoms or defects in the two cases. In nominally undoped and Si-doped AlGaN, n-type conductivity is generally found20. It is thus suggested that the BX in our samples are most likely to be donor-bound excitons (DX). It has been well established that the most common donors in undoped AlGaN are ON (O substitutes the nitrogen site) and VN (nitrogen vacancy). Furthermore, ON is more easily to form compared with VN because of its relatively low formation energy20. As such, ON is usually the dominant donor in unintentionally-doped AlGaN. In the case of Si-doped AlGaN, however, SiGa (Si substitutes the Ga site) will form prior to ON because of an even lower formation energy20. In addition, Si is also found to suppress the incorporation of O by formation of Si-O bond21. As a result, the concentration of ON will decrease gradually as Si-doping concentration increases. Therefore, DX1 in sample-A and DX2 in sample-C are attributed to O-bound exciton and Si-bound exciton, respectively. For the medium-level doped sample-B, ON cannot be suppressed completely, two types of DX respectively appeared in sample-A (DX1) and sample-C (DX2) are hence both observable. As mentioned above, the binding energy of O-bound exciton in sample-A and Si-bound exciton in sample-C is 87.4 and 63.6\u2009meV, respectively. Such large DX binding energies have rarely been reported in III-nitrides system to our knowledge. The typical values of that for BX in GaN only vary from 6 to 25\u2009meV12, 13. Generally, the DX binding energy can be empirically estimated through Haynes\u2019s rule:  where and are the binding energies of the donor-bound exciton and donor itself, respectively. It has been reported that the binding energies of SiGa and ON in GaN are 30.18 and 33.20\u2009meV, respectively12. The derived binding energies of excitons bound to SiGa and ON in GaN followed the empirical Haynes\u2019s rule well with a constant of 0.214. As for AlN, Neuschl et al. found that the binding energy of Si-bound exciton was 28.5\u2009meV22. They estimated a value of 133\u2009meV for the binding energy of Si donor , assuming the same constant of 0.214. But it is more generally accepted that the binding energy of ON and SiGa in AlN is about 340 and 240\u2009meV, respectively23, 24. If so, the binding energy of Si-bound exciton and O-bound exciton in AlN should be 73 and 51\u2009meV, respectively. Using a linear interpolation approximation, the binding energy of O-bound exciton and Si-bound exciton in bulk Al0.35Ga0.65N is 30.1\u2009meV and 21.8\u2009meV, respectively. However, the corresponding values in our MQWs samples reach up to 87.4 and 63.6\u2009meV, respectively, about 2.9 times of that in bulk Al0.35Ga0.65N. It demonstrates that the strong quantum confinement in MQWs indeed leads to a great enhancement of the DX binding energy, which is consistent with the calculation for a finite potential well25. The PL spectrum from each of our samples shows that the peak intensity of the FX luminescence is stronger than that of BX luminescence. However, in the case of bulk GaN, it has been reported that the PL spectra are usually dominated by BX luminescence at low temperature when FX and BX are observed simultaneously12, 13, 14. It is suggested that this discrepancy in peak intensity ratio originates from the difference in the density and oscillator strength of FX and BX, as discussed below. First, FX has two main channels to relax at 10\u2009K: radiative recombination and to be captured by impurities or defects forming DX. Therefore, the density of FX and BX is decided by these two competitive processes, which are characterized by FX radiative recombination lifetime \u03c4r and FX capture time \u03c4tr, respectively. The FX capture time can be expressed as:  where is the capture cross-section, N is trap concentration, v is the thermal velocity of FX diffusion, and aX is the Bohr radius of FX. In the case of GaN, it is reported that \u03c4r and \u03c4tr are 375 and 16\u2009ps at 4\u2009K, respectively11. That implies that the chance of FX luminescence is smaller than FX capture, which is in favor of BX formation. For bulk AlGaN, the Bohr radius aX becomes smaller than that of GaN26. Moreover, we have to consider that in the case of AlGaN/AlGaN MQWs, aX will decrease sharply because of being compressed along the growth direction. A smaller aX represents a larger overlap of the electron and hole wavefunction for FX radiative recombination process as well as a smaller capture cross-section \u03c3X for FX capture process. This leads to a shorter FX lifetime \u03c4r and a longer capture time \u03c4tr, resulting in a decrease of the density of BX27. Second, the oscillator strength of FX and BX is proportional to and , respectively28, 29. As mentioned above, the Bohr radius aX of AlGaN in MQWs decreases sharply compared with that in GaN, leading to a salient increase in the oscillator strength of FX and a sharp decrease in the oscillator strength of BX. As a result, the transition probability of FX increases, at the expense of that of BX. Under the combined influence of density and oscillator strength, the peak intensity of the FX luminescence obviously exceeds that of the BX luminescence for our MQWs samples. It is worth noting that the above analysis about the Bohr radius neglected the quantum-confined Stark effect (QCSE), because the large band offset and narrow well width in our samples will result in a high energy level above the triangular potential wells, meaning that the QCSE is very weak30. Excitation-power-dependent PL was employed to confirm the nature of the FX and BX peaks, as presented in Fig. 2(b). The dependence of the integrated PL intensity of the short-wavelength-side peaks on the excitation-energy density gives approximately I\u2009\u221d\u2009P, indicating that the luminescence results from FX recombination. While the integrated PL intensity of the long-wavelength-side peaks increase sublinearly with the excitation power. The power exponent is 0.88 for sample-A and 0.87 for sample-C, respectively. This is due to the saturation of the BX radiative recombination process, which results from the finite donor concentration. For sample-B, DX1 peak and DX2 peak are hard to distinguish because they are too close to each other. Only the dependence of their total integrated PL intensity on the excitation-energy density can be obtained with a power exponent of 0.76. All these results support our peak recognition. Figure 3 (a)\u2013(c) show temperature-dependent PL spectra from 10\u2009K to 300\u2009K. The FX and DX in all samples show obvious PL intensity decrease with temperature. In particular, the DX intensities show faster decrease than those of FX as temperature increases. The internal quantum efficiency (IQE), estimated as the integrated PL intensity at room temperature divided by that at 10\u2009K, is 33.7%, 38.2%, and 45% for sample-A, sample-B, and sample-C, respectively. The different temperature characteristics of DX and FX are attributed to different thermal activated processes, as discussed below. The decrease of the DX PL intensity is mainly due to DX dissociation, which can be described by:  where D and X refer to donor and free exciton, respectively. The activation energy of the DX dissociation is approximately equal to the binding energy. On account of the large binding energies of DX1 (87.4\u2009meV) and DX2 (63.6\u2009meV), the DX peaks can be well identified even at 160\u2009K in sample-A and 130\u2009K in sample-B and -C. It is worth mentioning that DX1 and DX2 luminescence can be seen in almost all the samples at intermediate temperatures. The explanation of the fact is that there should be tiny amounts of Si residue in the reactor chamber after n-AlGaN growth. In addition, O contamination can never be completely avoided for MOCVD growth. Therefore, Si-related and O-related excitons should exist at the same time. Only at low temperature, the donor-bound exciton luminescence associated with the higher-concentration one should be dominant. The lower-concentration-donor-bound exciton luminescence would be covered up because the spacing between DX1 and DX2 are too close. At intermediate temperatures, however, DX1 and DX2 luminescence could both be observed with similar but weak intensity. The decay of the FX PL intensity is usually caused by more than one nonradiative recombination channels, but usually dominated by a high-activation-energy process. For understanding of the FX quenching mechanisms, the FX integrated PL intensities from 10 to 300\u2009K in Fig. 4 (dots) are analyzed by Arrhenius plots fitting (lines). Assuming that there are two dominated thermally activated processes, the temperature-dependent FX integrated PL intensity I(T) can be modeled by:  where I0 is the FX integrated PL intensity at 10\u2009K, A and B are rate constants, Ea and Eb are the activation energies of the nonradiative recombination processes, and kB is the Boltzmanm\u2019s constant31. This expression provides a very good fit to our experimental datas with Ea being 9, 12, and 15\u2009meV for sample-A, -B, and -C, respectively. Simultaneously, Eb is 100, 105, and 120\u2009meV for sample-A, -B, and -C, respectively. The detailed results are displayed in Table 1. The first quenching mechanism (characterized by Ea) is attributed to the delocalization of excitons from potential fluctuations in the AlGaN well layers. It has been reported that a thickness fluctuation of 1 monolayer in a narrow well layer will make a significant difference to the confinement energies32. The thickness of our well layers is as narrow as about 10 monolayers, therefore, the potential variations in the well layers should be dominated by well/barrier interface roughness. The localization energy caused by interface roughness in our samples is obviously small, implying an abrupt MQWs interface. The value of Eb increases with Si-doping level. This may result from suppression of the nonradiative recombination which is generally related to threading dislocation. Wet etching techniques are used to check that. As shown in Fig. 5, AFM images show a remarkable reduction of TDD with increase of the Si-doping concentration, in good agreement with our speculation. So we hold the view that a reduced TDD caused by Si-doping leads to a higher activation energy for FX quenching, thus an increased IQE. In summary, low temperature PL spectra (10\u2009K) of Al0.5Ga0.5N/Al0.35Ga0.65N MQWs identify a binding energy of 87.4\u2009meV for BX in undoped sample, and 63.6\u2009meV for BX in Si-doped (2\u2009\u00d7\u20091018\u2009cm\u22123) sample, referring to O-bound exciton and Si-bound exciton, respectively. The large binding energies of BX are 2.9 times of that in bulk Al0.35Ga0.65N estimated by a linear interpolation approximation. This significant increase in binding energies is assumed to originate from the strong quantum confinement in MQWs. Much higher FX PL peak intensity in comparison with BX is suggested to result from a smaller Bohr radius of FX in Al0.5Ga0.5N/Al0.35Ga0.65N MQWs. Si-doping are found to suppress the FX quenching by reducing TDD in the well layers, leading to a significant improvement of IQE from 33.7% to 45%. In this study, three MQWs samples (sample-A, -B, and -C) were grown on 2-in. (0001) sapphire substrates by low pressure metal organic chemical vapor deposition (LP-MOCVD). Deposition was initiated from a 1-\u03bcm-thick AlN layer, followed by a multi-period AlN/AlGaN superlattice (SL) layer and a 1-\u03bcm-thick Si-doped AlGaN layer. The active region consists of five 2.5-nm-thick Al0.35Ga0.65N well layers separated by 10-nm-thick Al0.5Ga0.5N barrier layers. Finally, the structure was completed with a 25-nm-thick Al0.5Ga0.5N cap layer. A cross section schematic of the MQWs samples is shown in Fig. 1. A 4th harmonic of Q-switched YAG:Nd laser (\u03bb\u2009=\u2009266\u2009nm, pulse width\u2009=\u20097\u2009ns) was used for PL excitation, and an Ocean Optics USB2000+VIS-NIR fiber optic spectrometer was employed to record the PL spectra. A closed-cycle helium cryosystem provided the variation of temperature in a range from 10\u2009K to 300\u2009K. Excitation power tuning was realized by THORLABS NUK01 neutral density filters. The surface morphology for sample-A, -B, and -C after molten KOH etching was characterized by Bruker Dimension ICON-PT atomic force microscopy (AFM). How to cite this article: He, C. et al.

Because of the large detection depth of HX-PES (\u223c20 nm), the spectra contain both surface and bulk information due to the surface band bending. The In  Ga N films ( = 0-0.21) exhibited upward surface band bending, and the valence band maximum was shifted to lower binding energy when the mole fraction of InN was increased.

N-Al 0.5 Ga 0.5 N showed an excellent 2D growth at a growth rate of 0.55\u00a0\u00b5m/h. An almost pit-free surface was realized by lowering the V/III ratio. Finally, the electron concentration and mobility of the optimized n-Al 0.5 Ga 0.5 N reached up to 4.2\u00d710 18 \u00a0cm \u22123  and 48.2\u00a0cm 2 /(V\u00a0s), respectively.

Increasing the Al composition of AlGaN in the multiplication layer from 0.40 to 0.45 was calculated to significantly reduce the excess noise factor of this heterojunction APD. The polarization electric field induced in the multiplication layer had the same direction as the applied reverse bias field, which helped lower the avalanche breakdown voltage. The calculated results demonstrated that the apparent spike in the electric field intensity at the i-Al0.4Ga0.6N/n-Al0.5Ga0.5N interface can be effectively suppressed by inserting a grading n-AlGaN layer, which helps reduce the dark current.",

The location and thickness of AlGaN layer with higher Al-content in the step-like QWs are confirmed to significantly affect the distributions and overlap of electron and hole wavefunctions. The best material characteristic is obtained when the step-like QW is designed as an asymmetric structure, such as Al 0.74 Ga 0.26 N (1.8\u00a0nm)/Al 0.64 Ga 0.36 N (1.2\u00a0nm), where AlGaN with higher Al-content layer is set to be located nearer from n-side and be thick as far as possible.

The best full width at half maximum values for (0002) and (1     1  \u00af     02) reflections are 207 and 377 arcsec, respectively. Investigations indicate the joint effect of growth mode control and sputtered buffer layer results in the improvement of AlN crystalline quality. Firstly, threading dislocations density can be significantly decreased due to the alteration from three-dimensional to two-dimensional growth mode. Moreover, the graded composition of AlON layer in the sputtered buffer layer is believed to alleviate lattice mismatch between sapphire substrates and AlN, which also contributes to low dislocations density in AlN templates.",

Cathodoluminescence (CL) mappings identify that the emission at 290\u00a0nm originates from the macrostep edges. Potential minima induced by local variation of QW thickness and Ga incorporation are found along the step edges, where quantum wires (QWRs) are formed. The lateral advance rate of macrostep (\u223c310\u00a0nm/h) is obtained by investigating the distribution of QWRs. Temperature-dependent CL spectrum suggest that thermal quenching for 290\u00a0nm emission is dramatically suppressed compared with that for conventional QWs emission, which shows excitonic localization characteristics of QWRs.",

        "abstract": "The crystal quality evolution of AlN films via high-temperature (HT) annealing under nitrogen is investigated. It is found that the best crystal quality can be realized using an optimized combination of the annealing temperature at 1700 \u00b0C and an AlN thickness of 540 nm, respectively. Thus the X-ray diffraction \u03c9-scan full width at half maximum (FWHM) values of 59 and 284 arcsec for (0002) and (102) diffractions were achieved, respectively. It is verified that the significant reduction in the threading dislocation density (TDD) via HT annealing starts from the interface zone between AlN and sapphire anterior to the zone far from the interface, which is caused by less energy being required to decrease the larger twist angle among the columns in the interface zone. Benefiting from the low-TDD annealed AlN template, the internal quantum efficiency of the 282-nm AlGaN-based multiple quantum wells reached 57% at 300 K.",

X-ray diffraction reciprocal space mapping (XRD RSM) demonstrated that the AlGaN epilayers with different stresses have large Al composition differences despite the same growth conditions. The largest Al composition difference reached up to 21.3%, which was also confirmed using secondary ion mass spectroscopy (SIMS). This result is attributed to a large stress discrepancy in the AlGaN epilayers. Finally, the dependences of the solid-phase Al composition on the gas-phase Al composition under different stresses were systematically analyzed.",

Here, we proposed a strategy to obtain high-quality AlN film by combining growth-mode modification with sputtered AlN buffer using metal\u2013organic chemical vapor deposition (MOCVD). Compared with the MOCVD AlN buffer, the sputtered AlN buffer consists of smaller and more uniform grains with better c-axis orientation, leading to a better growth-mode modification in the subsequent growth process. On one hand, the better c-axis orientation is inherited by the upper AlN epilayer, resulting in a lower screw dislocation density. On the other hand, the better growth-mode modification significantly suppresses edge dislocations by producing high-density nanoscale voids and many 90\u00b0 bent dislocations. Therefore, the total threading dislocation density of the AlN film grown on the sputtered AlN buffer is dramatically reduced to an extremely low va...",

It is found that there is a significant enhancement of light output power (LOP) and efficiency droop for DUV-LEDs with the inserted higher Al-content AlGaN layer compared to those with the conventional one. The location of the AlGaN layer with higher Al-content in the MQWs is proven to greatly affect the distribution of carriers and the overlap of electron and hole wave functions. The optimal structure can be achieved when the higher Al-content layer is placed on the right side within the MQWs. The key factors for the performance improvements for this specific design is the enhanced hole transport and reduced electron leakage.",

The self-terminated precision gate recess is realized by inserting a thin AlN/GaN bilayer in the AlGaN barrier layer. The gate recess is stopped automatically at the GaN insertion layer after high-temperature oxidation and wet etch, leaving a thin AlGaN barrier to maintain a quantum well channel that is normally pinched off. With addition of an Al 2 O 3  gate dielectric, quasi normally OFF GaN MOSHEMTs have been fabricated with high threshold uniformity and low ON-resistance comparable with the normally ON devices on the same wafer. A high channel mobility of 1400 cm   $^{2}/textrm {V}cdot textrm {s}$    was obtained due to the preservation of the high electron mobility in the quantum-well channel under the gate.",

It is found that the degree and time scale of the shift in threshold voltage are consistent with the density and time constant of interface traps at the MOS interface. The device based on wet etching delivers higher interface quality and threshold voltage stability than that based on dry etching. Nitrogen deficiency and high oxygen coverage are considered to be the origins of the high interface trap density in the MOSFET fabricated by dry etching.",

        "abstract": "Time-dependent OFF-state leakage behavior of AlGaN/GaN MISHEMTs on silicon substrate is investigated and a novel degradation mechanism is proposed in this paper. Under constant high voltage OFF-state stress, drain leakage current gradually increases with stress time and the behavior is gate bias and temperature-dependent. Consecutive OFF-state breakdown measurement with drain injection technique indicates that the negative shift of threshold voltage (   $V_{mathrm {th}}$   ) is responsible for the increase of drain leakage current during stress measurement. It is proposed that the negative shift of    $V_{mathrm {th}}$    is mainly induced by the ionization of uncompensated donor like deep levels near the channel, which are most likely to be located in the 300-nm-thick unintentionally doped GaN layer above the carbon doped buffer layer.",

The thin AlN layer serves the dual role of protecting the gate channel region from direct plasma bombardment during the RIE Si 3 N 4  removal and passivating the surface states in the access region. As a result, the effective carrier mobility in the normally-off channel is found to improve from the 568 cm 2 /   $text {V}cdot text {s}$    in conventional Si 3 N 4  passivation process to a high value of 1154 cm 2 /   $text {V}cdot text {s}$   .

The device with a drift length of 3 \u03bcm features a threshold voltage of 1.7 V and an output current of 430 mA/mm at 8 V gate bias. The off-state breakdown voltage (BV) is as high as 1021 V (800 V) defined at a drain leakage criterion of 10 \u03bcA/mm with floating (grounded) substrate. The corresponding breakdown electric field is 3.4 MV/cm and the Baligau0027s figure-of-merit (BFOM) is 1.6 GW/cm 2 . A small degradation of the dynamic on-resistance (R on, d ) about 30% is observed with a short pulse width of 500 ns and a quiescent drain bias of 60 V. The record value is supposed to benefit from the intrinsic step-graded field plate, high quality LPCVD SI3N4 passivation and material optimization of 4.5 \u03bcm thick epitaxial layer.",

The recess-free process is achieved by an ultrathin-barrier (UTB) AlGaN/GaN heterostructure that features a natural pinched-off 2-D electron gas channel. The top\u2013down manufacturing technique overcomes the challenges in etching of AlGaN barrier with well-controlled depth and uniformity, which is especially attractive for fabrication of normally OFF GaN-based high-electron-mobility transistors (HEMTs) and metal\u2013insulator\u2013semiconductor HEMTs (MIS-HEMTs) on large-size Si substrate. With SiN x  passivation grown by low-pressure chemical-vapor deposition, on-resistance of the UTB-AlGaN/GaN-based power devices can be significantly reduced. High-uniformity low-hysteresis normally OFF HEMTs and Al 2 O 3 /AlGaN/GaN MIS-HEMTs are successfully demonstrated on the UTB AlGaN/GaN-on-Si platform. It is also a compelling technology platform for manufacturing high-performance GaN-based lateral power diodes, and normally OFF p-(Al)GaN heterojunction field-effect transistors.",

        "title": "Characterization of 880 V Normally Off GaN MOSHEMT on Silicon Substrate Fabricated With a Plasma-Free, Self-Terminated Gate Recess Process",
        "abstract": "In this paper, we report the device performance of a high-voltage enhancement-mode (E-mode) GaN MOSHEMT on silicon substrate. Normally off operation is realized by a self-terminated precision gate recess process on an optimized high-electron mobility transistor structure. The GaN MOSHEMT is fully pinched off at zero gate bias, suggesting a \u201ctrue\u201d normally off operation. The threshold voltage is 0.4 V with a drain current density of 1    $mu text{A}$   /mm as the criteria. The device with 15-   $mu text{m}$    gate-drain distance and 100-   $mu text{m}$    gate width exhibits a maximum drain current of 356 mA/mm at 8-V gate bias. The on/off current ratio of the device is larger than 10 10  with a subthreshold slope of 80 mV/dec. The gate leakage current is below 10 \u22127  mA/mm up to 9-V gate bias. The off-state breakdown voltage (BV) is as high as 1528 V (880 V) measured with floating (grounded) silicon substrate at a drain leakage current criterion of 5    $mu text{A}$   /mm. The specific on-resistance (   ${R}_{text {ON,SP}}$   ) of the device is 2.79    $text{m}Omega cdot$   cm 2 , and the power figure of merit (BV 2 /   ${R}_{ text {ON,SP}}$   ) is 277 MW/cm 2 . High-voltage pulsed I\u2013V measurement indicates that the dynamic on-resistance is only 1.6 times the static one with a pulsewidth of 10    $mu text{s}$    at 400-V off-state quiescent drain bias. The high performance of the normally off GaN MOSHEMT is supposed to benefit from the high quality low pressure chemical vapor deposition Si 3 N 4  passivation layer and the advanced E-mode device fabrication process.",

The LPCVD Si 3 N 4  serves the dual role of gate-recess mask and passivation layer. Unlike conventional oxidation etching process using Si 3 N 4  as post gate-recess passivation, the gate channel region was prevented from additional plasma bombardment during the gate window re-opening.

        "abstract": "In this letter, we demonstrate a recessed-anode Schottky barrier diode (SBD) on a double AlGaN/GaN heterojunction structure. A self-terminated, oxidation/wet etching with low-pressure chemical vapor deposition (LPCVD) Si 3 N 4  mask is applied in the anode recess process. Unlike common plasma-based, dry etching techniques, the etched surface is not subjected to ion bombardment, and the etch depth is precisely controlled. As a result, a high effective channel mobility of 1079 cm 2 /   $text {V}~cdot ~text {s}$    is maintained in the channel beneath the recess surface. The fabricated devices with a 15-   $mu text{m}$    anode-to-cathode distance (   ${L} _{mathrm {AC}}$   ) are found to exhibit a uniform, low turn-ON voltage (   ${V}_mathrm {ON}$   ) of 0.69 \u00b1 0.03 V, and a low specific on-resistance (   ${R} _{mathrm{ON,SP}}$   ) of 2.83    $text{m}Omega cdot text {cm}^{2}$   . The SBDs also show excellent off-state blocking characteristics due to the smooth recess interface together with the assistance of LPCVD grown Si 3 N 4 . A breakdown voltage of 1190 V is achieved for the SBDs with 15-   $mu text{m}~{L} _{mathrm {AC}}$    at a leakage current criteria of    $1~mu text{A}$   /mm, and the Baliga\u2019s figure-of-merit is 500 MW/cm 2 .",

Analytical solutions are derived for frequency dispersion of the heterostructure\u2019s capacitance measured on two concentric-circle Schottky contacts, in form of Bessel function, by modeling a distributed network of heterostructure and solving corresponding circular transmission line functions. Solutions reveal C\u2013f is determined by the R s  of 2-D electron gas (2-DEG). So in reverse, the sheet resistance at a certain carrier density can be extracted from the C\u2013f measurement. By fitting experimental C\u2013f data with the model, we obtain a peak mobility of 2044 cm 2 /   $text {V}cdot text {s}$    corresponding to a 2-DEG density of    $8.2 times 10^{12}$    cm \u22122  and a sheet resistance of    $373~Omega / square$    on an Al 0.25 Ga 0.75 N/GaN heterostructure on silicon substrate.

The PL lifetime for resonant regime is 0.088\u00a0ns, which is 40\u00a0% lower than that of non-resonant regime for 120\u00a0nm nanorod LED array.

The interruption comparing with continuous supply of silane flow was performed to study the role of silane flux. High resolution scanning electron microscopy (SEM), x-ray diffraction (XRD), cathodoluminescence (CL) and x-ray photoelectron spectroscopy (XPS) measurements were performed. The enhanced vertical growth rate was achieved as 42\u00a0\u03bcm/h and sharp smooth m-plane, r-plane and c-plane facets were obtained for the nanorods with high silane flux. Si N bonds were clarified to be formed on the surface of the nanorod by XPS spectra. The silane acting as anti-surfactant was suggested to explain the diffusion and incorporation of the species on the facets of GaN nanorods.",

The thickness of the nucleation layer (NL) was optimized as 15 nm.

X-ray diffraction (XRD) \u03c9/\u03c6-scans, cathodoluminescence (CL) mapping and transmission electron microscopy (TEM) measurements were carried out to study the GaN coalescence process on NPSS. Nano-nucleating, lateral growth and the submerging of the large tilt grains were confirmed as the primary factors that reduced the TDD and residual stress. The mechanism for GaN nucleation on NPSS and its effect on the subsequent growth stages were elucidated.",

Photoluminescence (PL) suppression and CL enhancement were obtained for the same green LED sample with the Ag NP array. Time-resolved PL (TRPL) results indicate strong coupling between the LSP and the QWs. Three-dimensional (3D) finite difference time domain (FDTD) simulation was performed using a three-body model consisting of two orthogonal dipoles and a single Ag NP. The LSP&ndash;QWs coupling effect was separated from the electron-beam (e-beam)&ndash;LSP&ndash;QW system by linear approximation. The energy dissipation was significantly reduced by the z-dipole introduction under the e-beam excitation. In this paper, the coupling mechanism is discussed and a novel emission structure is proposed.",

        "abstract": "The deep level traps and the electrical properties of fluorine plasma treated (F-treated) and non-treated Al0.83In0.17N/AlN/GaN Schottky barrier diodes (SBDs) were investigated by the temperature-dependent current\u2013voltage (I\u2013V) and deep level transient spectroscopy (DLTS) measurements. Three deep level traps were detected in the SBD after F-treatment at ~E c \u2212 0.17 eV, ~E c \u2212 0.27 eV and ~E c \u2212 1.14 eV. One of the deep level traps at ~E c \u2212 1.14 eV is mainly located in the Al0.83In0.17N barrier layer with a captured cross section (\u03c3) of ~6.50 \u00d7 10\u221218 cm2. This F-related deep level trap has 3\u20134 orders of magnitude of the larger \u03c3 and ~0.46 eV greater active energy than that of the dislocation-related one at ~E c \u2212 0.68 eV with \u03c3 of ~1.92 \u00d7 10\u221221 cm2. Meanwhile, the leakage current of F-treated SBD at \u22125 V is reduced by ~2 orders of magnitude compared with that of the non-treated one. This leakage current reduction is mainly attributed to the increase of the Poole\u2013Frenkel emission barrier height from ~0.09 eV in non-treated SBD to ~0.46 eV in the F-treated one. It is believed that the main reverse current transportation is the Poole\u2013Frenkel emission from the F-related deep level trap states into the continuum states of the dislocations in F-treated Al0.83In0.17N/AlN/GaN SBD.",

        "abstract": "A volcano-shaped nano-patterned sapphire substrate (VNPSS) was fabricated by nanoimprint lithography and wet etching. The edge effects were used to form a ring mask for wet etching. The widths of the SiO2 rings were obtained as 136 and 91 nm by changing the reactive ion etching time. The crystal planes were determined to be {10} and {10} for the etching facets of the outside and inside of the ring, respectively. X-ray diffraction rocking curves indicate that the dislocation density of the GaN epilayer on the VNPSS is lower than that on the nano-patterned sapphire substrate (NPSS). Temperature-dependent photoluminescence results show that the internal quantum efficiency of the GaN-based light emitting diode (LED) on the VNPSS is 24% larger than that on the NPSS, which is due to the improved crystal quality. 3-D finite difference time domain (FDTD) simulations show that the light extraction efficiency (LEE) of the GaN-based LED on the VNPSS is 21% more than that of the LED on the NPSS, which conforms to the LEE enhancement by PL measurement. The use of edge effects provides ideas for preparing complex NPSS patterns with commonly used imprint stamps to further increase crystal quality and LEE.",

        "abstract": "Ag nanoparticles (NPs) are fabricated on the cross-section of green emitting quantum wells (QWs). The effect of the dipole polarization orientation on the localized surface plasmon (LSP)-QW coupling can be studied by setting the incident direction of the electron beam parallel to the plane of the QWs. Cathodoluminescence (CL) measurements on the QWs show that the intensity with the Ag NPs is enhanced 6.1 times compared with that without the Ag NPs. Total energy loss profiles for an electron beam in the GaN and Ag NP are accurately simulated using a Monte Carlo program (CASINO). The orientations of the in-plane dipoles in the QWs can vary from 0\u00b0 to 360\u00b0. Through a two-step simulation process using the three-dimensional (3D) finite difference time domain (FDTD) method, the weighted average of CL intensities are simulated for QWs with the Ag NPs. The simulation results agree well with the experimental results. Lastly, the dipole orientation dependent LSP-QW coupling process is discussed.",

        "abstract": "The characteristics of polarizations, including spontaneous polarization (PSP) and piezoelectric polarization (PPE) in Al0.25Ga0.75N/AlN/GaN were obtained by temperature-dependent x-ray diffraction measurements of AlN and GaN layers, and the sheet carrier density (ns) in 20-nm-thick barrier Al0.25Ga0.75N/AlN/GaN heterostructure was studied by Hall measurement at different temperatures from 300\u2009K to 600\u2009K. It is found that the PSP/e (\u223c1\u2009\u00d7\u20091013\u2009cm\u22122, e is the electron charge) is larger than PPE/e (\u223c7\u2009\u00d7\u20091012\u2009cm\u22122). Excluding the influence of background carrier density, the change of PSP/e with temperature is similar to that of ns, while the tendency of PPE/e is opposite. The contributions to ns change by PSP and PPE are \u223c\u22127.3\u2009\u00d7\u20091011\u2009cm\u22122 and \u223c1.9\u2009\u00d7\u20091011\u2009cm\u22122, respectively. Therefore, the total variation of PSP and PPE is \u223c\u22125.4\u2009\u00d7\u20091011\u2009cm\u22122, which is close to the value \u223c\u22125.5\u2009\u00d7\u20091011\u2009cm\u22122 obtained by Hall data.

        "abstract": "Voluntary help during a time of need fosters interpersonal gratitude, which has positive social and personal consequences such as improved social relationships, increased reciprocity, and decreased distress. In a behavioral and a functional magnetic resonance imaging (fMRI) experiment, participants played a multiround interactive game where they received pain stimulation. An anonymous partner interacted with the participants and either intentionally or unintentionally (i.e., determined by a computer program) bore part of the participants' pain. In each round, participants either evaluated their perceived pain intensity (behavioral experiment) or transferred an amount of money to the partner (fMRI experiment). Intentional (relative to unintentional) help led to lower experience of pain, higher reciprocity (money allocation), and increased interpersonal closeness toward the partner. fMRI revealed that for the most grateful condition (i.e., intentional help), value-related structures such as the ventromedial prefrontal cortex (vmPFC) showed the highest activation in response to the partner's decision, whereas the primary sensory area and the anterior insula exhibited the lowest activation at the pain delivery stage. Moreover, the vmPFC activation was predictive of the individual differences in reciprocal behavior, and the posterior cingulate cortex (PCC) activation was predictive of self-reported gratitude. Furthermore, using multivariate pattern analysis (MVPA), we showed that the neural activation pattern in the septum/hypothalamus, an area associated with affiliative affect and social bonding, and value-related structures specifically and sensitively dissociated intentional help from unintentional help conditions. These findings contribute to our understanding of the psychological and neural substrates of the experience of interpersonal gratitude and the social consequences of this emotion.

        "abstract": "Polarization in InGaN quantum-wells (QWs) is the key issue for GaN-based light emitting diodes (LEDs). Kelvin probe force microscopy (KPFM) is used to detect the strain relaxation distribution on the mesa of micro LEDs (\u00b5LEDs). The results of KPFM are analyzed with the help of numerical calculation. The effects of space charge layer (SCL) and polarization on the band structures are taken into consideration. Comparing the data of KPFM getting from \u00b5LEDs with different diameter, the smaller size \u00b5LEDs have larger area affected by strain relaxation. This phenomenon guarantees the excellent performance for \u00b5LEDs.",

        "abstract": "Carbon (C) doping is essential for producing semi-insulating GaN for power electronics. However, to date the nature of C doped GaN, especially the lattice site occupation, is not yet well understood. In this work, we clarify the lattice site of C in GaN using polarized Fourier-transform infrared and Raman spectroscopies, in combination with first-principles calculations. Two local vibrational modes (LVMs) at 766 and 774\u2009\u2009cm^{-1} in C doped GaN are observed. The 766\u2009\u2009cm^{-1} mode is assigned to the nondegenerate A_{1} mode vibrating along the c axis, whereas the 774\u2009\u2009cm^{-1} mode is ascribed to the doubly degenerate E mode confined in the plane perpendicular to the c axis. The two LVMs are identified to originate from isolated C_{N}^{-} with local C_{3v} symmetry. Experimental data and calculations are in outstanding agreement both for the positions and the intensity ratios of the LVMs. We thus provide unambiguous evidence of the substitutional C atoms occupying the N site with a -1 charge state in GaN and therefore bring essential information to a long-standing controversy.",

The optical polarization properties of the conventional and staggered AlGaN QWs are investigated by a theoretical model based on the k\u00b7p method as well as polarized photoluminescence (PL) measurements. Based on an analysis of the valence subbands and momentum matrix elements, it is found that AlGaN QWs with step-function-like Al content in QWs offers much stronger TE polarized emission in comparison to that from conventional AlGaN QWs. Experimental results show that the degree of the PL polarization at room temperature can be enhanced from 20.8% of conventional AlGaN QWs to 40.2% of staggered AlGaN QWs grown by MOCVD, which is in good agreement with the theoretical simulation. It suggests that polarization band engineering via staggered AlGaN QWs can be well applied in high efficiency AlGaN-based DUV LEDs. ",

The zero Dresselhaus SOC suppresses the spin relaxation and increases the spin diffusion length, which is beneficial to spin manipulation. To achieve a device structure with Rashba SOC presence and Dresselhaus SOC absence to manipulate spin degree of freedom, ionic liquid gate was applied on a nanowire grown along [0001] crystallographic direction, and Rashba SOC was induced as expected.",

The band structure of monolayer MoS2 is well known to have a direct gap at K (K\u2032) point, whereas the second lowest conduction band minimum is located at \u039b point, which may interact with the valence band maximum at K point, to make an indirect optical bandgap transition. We experimentally demonstrate the direct-to-indirect bandgap transition by measuring the photoluminescence spectra of monolayer MoS2 under hydrostatic pressure at room temperature. With increasing pressure, the direct transition shifts at a rate of 49.4 meV/GPa, whereas the indirect transition shifts at a rate of \u221215.3 meV/GPa. We experimentally extract the critical transition point at the pressure of 1.9 GPa, in agreement with first-principles calculations. Combining our experimental observation with first-principles calculations, we confirm that this transition is caused by the K-\u039b crossover in the conduction band.",

For both diodes, it was found that the degree of polarization (DOP) decreased obviously as the injection current increased. We attribute the decrease in DOP to the different changing trend of the intensity of the light emission from transverse electric (TE) polarization (E\u22a5c) and transverse magnetic (TM) polarization (E\u2225c) as the injected carriers occupy higher states above k = 0 with increasing the injection current. For the 277 nm LED, even the polarization switching from TE to TM mode was observed.",

The films were used as Schottky contacts on AlGaN/GaN heterostructures. The Schottky behaviours of WNx contact was investigated under various annealing conditions by current\u2013voltage (I\u2013V ) measurements. The results show that the gate leakage current was reduced to 10-6 A/cm2 when the N2 flow is 400 mL/min. The results also show that the WNx contact improved the thermal stability of Schottky contacts. Finally, the current transport mechanism in WNx/AlGaN/GaN Schottky diodes has been investigated by means of I\u2013V characterisation technique at various temperatures between 300 K and 523 K. A TE model with a Gaussian distribution of Schottky barrier heights (SBHs) is thought to be responsible for the electrical behaviour at temperatures lower than 523 K.",

It compares with the Schottky diode without Aluminium inserting layer. The experimental results show that in the Schottky diode with Al layer the minimum point of I\u2013V curve drifts to the minus voltage, and with the increase of temperature increasing, the minimum point of I\u2013V curve returns the 0 point. The temperature dependence of gate-leakage currents in the novelty diode and the traditional diode are studied. The results show that the Al inserting layer introduces interface states between metal and Al0.245Ga0.755N. Aluminium reacted with oxygen formed Al2O3 insulator layer which suppresses the trap tunnelling current and the trend of thermionic field emission current. The reliability of the diode at the high temperature is improved by inserting a thin Al layer.",

        "abstract": "This paper investigates the temperature dependence of the specific resistance in annealed V/Al/V/Au (15 nm/85 nm/20 nm/95 nm) contacts on n-Al0.4Ga0.6 N. Contacts annealed at 700C and higher temperatures show Ohmic behaviour. Annealing at 800 C produces the lowest contact resistance. Samples annealed at 800C have been analysed by using cross-sectional transmission electron microscopy and an energy dispersive x-ray spectrum. Limited reaction depths are observed between V-based contacts and n-AlGaN. The VN grains are found to form in the contact layer of the annealed samples,which can be considered as the key to the successful formation of Ohmic contact. The contact layer adjacent to AlGaN material consists of V\u2013Al\u2013Au\u2013N,AlN and AlAu alloys.",

        "abstract": "Type-II band alignment structure is coveted in the design of photovoltaic devices and detectors, since it is beneficial for the transport of photogenerated carriers. Regrettably, for group-III-nitride wide bandgap semiconductors, all existing devices are limited to type-I heterostructures, owing to the unavailable of type-II ones. This seriously restricts the designing flexibility for optoelectronic devices and consequently the relevant performance of this material system. Here we show a brandnew type-II band alignment of the lattice-matched In 0.17 Al 0.83 N/GaN heterostructure from the perspective of both experimental observations and first-principle theoretical calculations. The band discontinuity is dominated by the conduction band offset \u0394EC, with a small contribution from the valence band offset \u0394EV which equals 0.1 eV (with E(AlInN(VBM) being above E(GaN)(VBM)). Our work may open up new prospects to realize high-performance III-Nitrides optoelectronic devices based on type-II energy band engineering.",

        "abstract": "By solving the Schr\ue54fdinger and Poisson equations self-consistently, the central barrier height, central barrier width, well width, and doping concentration in the barriers of symmetric Al_ 0.75 Ga_ 0.25 N/GaN double quantum wells (DQWs) have been studied to investigate their influences on the wavelength and absorption coefficient of intersubband transitions (ISBTs). A smaller wavelength of the ISBT between the first odd and the second even order subbands (S_ 1odd -S_ 2even ISBT) in Al_ 0.75 Ga_ 0.25 N/GaN DQWs and a larger absorption coefficient of the S_ 1odd -S_ 2even ISBT were obtained with decreased central barrier height, when the central barrier height was larger than 0.62 eV. The wavelength of the S_ 1odd -S_ 2even ISBT decreases, and the absorption coefficient of the S_ 1odd -S_ 2even ISBT increases, when the width of the central barrier is reduced. On the other hand, decreasing the width of the well will result in smaller wavelength of the S_ 1odd -S_ 2even ISBT and larger absorption coefficient of the S_ 1odd -S_ 2even ISBT when the width of the well is narrower than 1.9 nm. When doping concentration in the barriers is smaller than 10~ 18 /cm~3, the wavelength of the S_ 1odd -S_ 2even ISBT is unchanged, while the absorption coefficient of the S_ 1odd -S_ 2even ISBT increases with the doping concentration. These results provide useful guidance for realization of ultrafast two-color optoelectronic devices operating in the optical communication wavelength range.",

In this work, spin transport properties of two-dimensional electron gas in Al(x)Ga(1-x)N/GaN heterostructure were studied by helicity-dependent photocurrent measurements at room temperature. Spin-related photocurrent was detected under normal incidence of a circularly polarized laser with a Gaussian distribution. On one hand, spin polarized electrons excited by the laser generate a diffusive spin polarization current, which leads to a vortex charge current as a result of anomalous circular photogalvanic effect. On the other hand, photo-induced spin polarized electrons driven by a longitudinal electric field give rise to a transverse current via anomalous Hall Effect. Both of these effects originated from the Rashba spin-orbit coupling. By analyzing spin-related photocurrent varied with laser position, the contributions of the two effects were differentiated and the ratio of the spin diffusion coefficient to photo-induced anomalous spin Hall mobility D(s)/\u03bc(s) = 0.08\u2005V was extracted at room temperature.",

Quasi-one-dimensional structures, possessing marked anisotropy gives more choice for the manipulation of the spin DOF since the concrete SOC form varies along with crystallographic directions. The anisotropy of the Dresselhaus SOC in cadmium selenide (CdSe) nanobelt and nanowire was studied by circular photogalvanic effect. It was demonstrated that the Dresselhaus SOC parameter is zero along the [0001] crystallographic direction, which suppresses the spin relaxation and increases the spin diffusion length, and thus is beneficial to the spin manipulation. To achieve a device structure with Rashba SOC presence and Dresselhaus SOC absence for manipulating the spin DOF, an ionic liquid gate was produced on a nanowire grown along the [0001] crystallographic direction, and the Rashba SOC was induced by gating, as expected.",

        "abstract": "Dirac-like surface states on surfaces of topological insulators have a chiral spin structure with spin locked to momentum, which is interesting in physics and may also have important applications in spintronics. In this work, by measuring the tunable helicity-dependent photocurrent (HDP), we present an identification of the HDP from the Dirac-like surface states at room temperature. It turns out that the total HDP has two components, one from the Dirac-like surface states, and the other from the surface accumulation layer. These two components have opposite directions. The clear gate tuning of the electron density as well as the HDP signal indicates that the surface band bending and resulted surface accumulation are successfully modulated by the applied ionic liquid gate, which provides a promising way to the study of the Dirac-like surface states and also potential applications in spintronic devices.",

It is found that under low energy electron beam irradiation, the band to band emission of GaN shows a decrease before hydrogenation, while it shows an initial increase and a subsequent decrease after hydrogenation, and the decrease after hydrogenation is relatively weak. Moreover, there is no luminescence recovery in 20 hours after the first irradiation after hydrogenation. The experimental results indicate a luminescence enhancement effect of hydrogen by passivating certain defects in GaN. However, such effect must be realized by overcoming high migration barrier in GaN. In the experiments, low energy electron beam supports enough energy to hydrogen to diffuse and passivate defects in GaN. These results show strongly the importance of diffusion of hydrogen in the passivation process in semiconductors.",

        "abstract": "Gate-defined quantum point contacts (QPCs) were fabricated with Al0.25Ga0.75N/GaN heterostructures grown by metal-organic chemical vapor deposition (MOCVD). In the transport study of the Zeeman effect, greatly enhanced effective g factors (g*) were obtained. The in-plane g* is found to be 5.5 \u00b1 0.6, 4.8 \u00b1 0.4, and 4.2 \u00b1 0.4 for the first to the third subband, respectively. Similarly, the out-of-plane g* is 8.3 \u00b1 0.6, 6.7 \u00b1 0.7, and 5.1 \u00b1 0.7. Increasing g* with the population of odd-numbered spin-splitted subbands are obtained at 14 T. This portion of increase is assumed to arise from the exchange interaction in one-dimensional systems. A careful analysis shows that not only the exchange interaction but the spin-orbit interaction (SOI) in the strongly confined QPC contributes to the enhancement and anisotropy of g* in different subbands. An approach to distinguish the respective contributions from the SOI and exchange interaction is therefore proposed.",

        "abstract": "AlxGa1-xN material has a direct band gap between 3.42 eV and 6.2 eV at room temperature,the corresponding cut-off wavelength flexible from 365 nm to 200 nm.It also covers the spectrum obtained with conventional gas and solid-state ultraviolet(UV) lasers,therefore it is necessary for UV photo-detector and deep-ultraviolet light emitting diodes(deep UV-LED).For the fabrication of these devices,thick AlxGa1-xN layer with high Al composition and high crystalline quality are essential.A major obstacle concerning the growth of such AlxGa1-xN layer is the large mismatches in the lattice constants and thermal expansion coefficients between the AlxGa1-xN and the commonly used substrate of sapphire.Crack start to be generated because of tensile strain at a thickness of less than 100 nm for Al0.25Ga0.75N once it directly grown on GaN/Sapphire.The production of crack-free thick AlxGa1-xN ternary layer with high Al composition has also been a challenging issue.It has been reported that low temperature AlN(LT-AlN) IL,or high temperature AlN(HT-AlN) IL,or AlN/ AlxGa1-xN SLs IL is introduced to improve the quality of AlxGa1-xN layer.Introduction of GaN/AlxGa1-xN superlattices(SLs) interlayer(IL) is an effective technique for releasing stress in AlxGa1-xN and decreasing TDs density in AlxGa1-xN epitaxial film.The influence of GaN/AlxGa1-xN superlattice(SLs) interlayer(IL) on the strain and threading dislocations(TDs) density of AlxGa1-xN epitaxial film grown on GaN/sapphire were investigated.Probing of phonon frequency by Raman scattering is one of the most convenient methods for charactering residual stress.The strain in AlGaN epitaxial film is obtained via Raman spectroscopy.Edge TDs density and screw TDs density of AlxGa1-xN film are obtained by X-Ray Diffraction(XRD).As thickness of superlattices period increase(well and barrier have the same thickness),both the edge TDs and the screw TDs density of AlxGa1-xN film decrease,and minimum tensile strain of AlxGa1-xN film is obtained for the sample with ten periods 5 nm/5 nm GaN/Al0.3Ga0.7N SLs IL.When the well thickness of GaN/Al0.3Ga0.7N superlattices is keeped and the barrier thickness of superlattices is increased to 8 nm,namely using ten periods 5 nm/8 nm GaN/Al0.3Ga0.7N SLs IL,compressive strain in AlxGa1-xN epitaxial film is achieved.Minimum TDs density of AlxGa1-xN film is obtained for the sample with ten periods 8nm/8nm GaN/Al0.3Ga0.7N SLs IL.The TDs density indicates that SLs IL can not only restrain edge TDs but also restrain screw TDs partly.Transmission electron microscopy(TEM) measurement demonstrates that the SLs IL can bend or end the TDs or make TDs incorporate,which can lead to TDs density reduction in AlxGa1-xN epitaxial film.And the inclination of edge TDs induced by relaxation strain in AlxGa1-xN film was observed,which resulted in a compressive strain relaxation of AlGaN layer.The strain relaxation of compressively strained AlxGa1-xN by inclined threading dislocation is calculated using TEM results.Above all,the AlxGa1-xN epitaxial film with compressive strain and low TDs density is obtained by the technique of GaN/AlxGa1-xN SLs IL.It is a foundation for the growth of AlxGa1-xN epitaxial film with high crystalline quality and high Al composition.",

The LPCVD Si3N4serves the dual role of gate-recess mask and passivation layer. Unlike conventional oxidation etching process using Si3N4as post gate-recess passivation, the gate channel region was prevented from additional plasma bombardment during the gate window re-opening. As a result, a high-effective channel mobility of 843 cm2/Vs, and low-channel resistance of 0.89\u03a9 mm are achieved for a normally OFF channel with LG= 1.5,\u03bcm. For 3\u03bcm LGD, the fabricated devices exhibit a threshold voltage (Vth) of 1.35 V, a maximum drain current of 500 mA/mm, a high ON/ OFF current ratio of 1010, and 560-V OFF-state breakdown voltage together with a low-forward gate leakage current of 10-7mA/mm up to 10 V.

        "abstract": "In this letter, we demonstrate a recessed-anode Schottky barrier diode (SBD) on a double AlGaN/GaN heterojunction structure. A self-terminated, oxidation/wet etching with low-pressure chemical vapor deposition (LPCVD) Si3N4mask is applied in the anode recess process. Unlike common plasma-based, dry etching techniques, the etched surface is not subjected to ion bombardment, and the etch depth is precisely controlled. As a result, a high effective channel mobility of 1079 cm2/ Vs is maintained in the channel beneath the recess surface. The fabricated devices with a 15- \u03bcm anode-to-cathode distance (LAC) are found to exhibit a uniform, low turn-ON voltage (VON) of 0.69 \u00b1 0.03 V, and a low specific on-resistance (RON,SP) of 2.83 m\u03a9 cm2. The SBDs also show excellent off-state blocking characteristics due to the smooth recess interface together with the assistance of LPCVD grown Si3N4. A breakdown voltage of 1190 V is achieved for the SBDs with 15- \u03bcm LAC at a leakage current criteria of 1\u03bcA/mm, and the Baliga's figure-of-merit is 500 MW/cm2. \u00a9 1980-2012 IEEE.",

        "abstract": "A gate-recessed normally OFF GaN metal-oxide-semiconductor high-electron-mobility transistor on silicon substrate has been fabricated using a self-terminated, plasma-free oxidation and wet etching process with pre-recess low-pressure chemical vapor deposition (LPCVD) Si3N4 passivation layer. The LPCVD Si3N4 serves the dual role of gate-recess mask and passivation layer. Unlike conventional oxidation etching process using Si3N4 as post gate-recess passivation, the gate channel region was prevented from additional plasma bombardment during the gate window re-opening. As a result, a high-effective channel mobility of 843 cm(2)/V . s, and low-channel resistance of 0.89 Omega . mm are achieved for a normally OFF channel with L-G = 1.5 mu m. For 3 mu m L-GD, the fabricated devices exhibit a threshold voltage (Vth) of 1.35 V, a maximum drain current of similar to 500 mA/mm, a high ON/OFF current ratio of similar to 1010, and 560-V OFF-state breakdown voltage together with a low-forward gate leakage current of similar to 10-7 mA/mm up to 10 V.

Methods MSCs were isolated from femur and tibia of male Wistar rats,and were cultured and passaged in vitro.Cell suspension was prepared after identification of differentiation of bMSCs into adipocytes.Fifty-four rats were randomly divided into sham operation group(n=18),bMSCs injection group(bMSC group,n=18) and normal saline infusion group(PS group,n=18).BMSCs were injected by the inferior vena cava in bMSC group when UUO model was set up,and normal saline of equal volume was injected in PS group.Rats were killed and renal tissues were harversted on the third,seventh and fourteenth day after model establishment.The mRNA expression of FasL was measured by RT-PCR,the protein expression was detected by immunohistochemical staining,the cell apoptosis was determined by TUNEL method,and the apoptotic index(AI) was calculated. Results Compared with sham operation group,the mRNA and protein expression of FasL and AI in bMSC group and PS group were significantly increased at each time point(P<0.05).Compared with PS group,the mRNA and protein expression of FasL and AI in bMSC group were significantly decreased on the third and seventh day after model establishment(P<0.05).There was no significant difference in each parameter on the fourteenth day between bMSC group and PS group(P>0.05).

        "abstract": "Modulation-doped Al0.22Ga0.78N/GaN heterostructures with various thickness of Si-doped Al0.22Ga0.78N barrier (n-AlGaN) were deposited on (0001)-oriented sapphire (\u03b1-Al 2O3) by atmosphere-pressure metal-organic chemical vapor deposition (MOCVD). The reciprocal space mappings (RSMs) of symmetric reflection (0002) and asymmetric reflection (1014) were measured by means of the high resolution X-ray diffraction (HRXRD). The results indicate that the microstructures and the strain status of the n-AlGaN barrier correlate to those of the underlying i-GaN layer. The strained n-AlGaN barrier starts to relax when its thickness is 75 nm. It is found that there exists an \"abnormal\" relaxation state (the strain parameter \u03b3 > 1) in modulation-doped Al0.22Ga0.78N/GaN heterostructures, which maybe results from the internal defects in Al0.22Ga0.78N barrier and the strain relaxation status at the i-GaN/\u03b1-Al2O3 interfaces.",

Measurement of the forward bias current-voltage behaviour of the device demonstrated a departure from the Shockley model of a p-n diode, and it was observed that the dominant mechanism of carrier transport across the junction is associated with carrier tunnelling. Electroluminescence experiments indicated that there was a main emission band around 2.80 eV and a relatively weaker peak at 3.2eV. A significant blueshift of the optical emission band was observed, which was consistent with the tunnelling character of electrical characteristics. Furthermore, the degradation in I - V characteristics and the low resistance ohmic short of the device were observed.",

It is thought that the misfit dislocations induced by the partially relaxed Al 0.22Ga 0.78N layer modulate the distribution of the piezoelectric polarization-induced charges at the Al 0.22Ga 0.78N/GaN heterointerface, and thus produce a strong modulation potential at the heterointerface.

Hall measurement indicates a given n-type background carrier concentration, and the electron Hall mobility is also given.

        "abstract": "Epitaxial growth of high quality hexagonal GaN films on sapphire substrates using light radiation heating metal-organic chemical vapor deposition (LRH-MOCVD) is firstly reported. The deposition temperature is 950 \u00b0C, about 100 \u00b0C lower than that in normal rf-heating MOCVD growth. The FWHM of GaN (0002) peak of x-ray diffraction rocking curve is 9.8 arc min. Photoluminescence spectrum of GaN film shows that there is a very strong band-edge emission and no `yellow-band' luminescence. Hall measurement indicates that the n-type background carrier concentration of GaN film is 1.7\u00d71018 cm-3 and the Hall mobility of it is 121.5 cm2/V.s. It is suggested that the radiation of light in GaN growth enhances the dissociation of ammonia and decreases the disadvantages of the parasite reaction between trimethylgallium and ammonia.",

However, nonstoichiometric In-rich InN can be oxidized at low temperature even as low as 300\u00b0C. And In-rich InN films are fully oxidized at 450\u00b0C. According to the scanning electron microscope (SEM) images, the oxidization of metal In grains on the surface of In-rich InN film is the main process at the temperature lower than 400\u00b0C. Above 400\u00b0C, metal In and InN begin to be oxidized simultaneously, which also indicates that stoichiometric InN is difficult to be oxidized at the temperature less than 400\u00b0C. \u00a9 2004 IEEE.",

The elastic scattering time \u03c4\u03b5, dephasing time \u03c4\u03a6 and spin-orbit(s-o) scattering time \u03c4so at various temperatures are obtained. The fitting parameters indicate that the inelastic scatterings to the 2DEG are mainly due to the piezoelectric field and the alloy disorder in the AlxGa1-xN barrier. When the second subband in the triangular quantum well at the heterointerface is occupied by the 2DEG, the anti-weak localization is observed clearly, which is due to the strong spin-orbit interaction. The spin-orbit effect dominates the quantum correction of the conductivity in the upper subband. The intersubband scattering becomes stronger with increasing temperature. \u00a9 2005 Trans Tech Publications, Switzerland.",

Frank partials in a Cu-contaminated specimen do not exhibit an EBIC contrast at room temperature when the specimen is cooled slowly; however, in the Fe-contaminated specimen, they exhibit EBIC contrast at room temperature due to their Fe contamination. The TEM micrograph shows that Cu develops precipitate colonies in the region away from stacking faults and does not precipitate on Frank partials in the specimen. The results indicate that Fe impurity decorates Frank partials more easily than Cu impurity in Si. ? 1996 American Institute of Physics. [S0003-6951(96)02002-3].",

The GaN active layer in MFS structures can reach inversion at the bias below 5 V, which is the applied voltage used in silicon-based integrated circuits. The surface carrier concentration of GaN layer in the MFS structure is deceased by one order compared with the background carrier concentration. The GaN MFS structures are promising for the practical application of GaN-based field effect transistors.",

Frank partials in a Cu-contaminated specimen do not exhibit an EBIC contrast at room temperature when the specimen is cooled slowly; however, in the Fe-contaminated specimen, they exhibit EBIC contrast at room temperature due to their Fe contamination. The TEM micrograph shows that Cu develops precipitate colonies in the region away from stacking faults and does not precipitate on Frank partials in the specimen. The results indicate that Fe impurity decorates Frank partials more easily than Cu impurity in Si. ? 1996 American Institute of Physics.",

Three deep trap centers Et1, Et2 and Et3 are found at 2.61, 3.10 and 2.11 eV above Ev respectively. Et1 is induced by superposition of the peak of O impurities and peak of N vacancies (or interstitial Al atoms). Because of the high growth temperature, Si atoms diffuse into the AlN layer and take the places of Al atoms and Si-N bonds are formed. After annealing, when the density of Si is higher than a critical one, some Si atoms take the places of N atoms and Al-Si bonds are formed. Et, is induced by Si-N bonds and Et3 by Al-Si bonds. It is also found that Et1 and Et2, the deep trap centers, are stable even after high temperature annealing for several hours.",

The PL spectra of GaN1-xPx show the largest red shift of 100 meV from the band-edge emission of GaN. XRD rocking curves show that the (0002) peak of GaN1-xPx shifts to smaller angles with increasing P content. The Raman spectra of GaN1-xPx, recorded in backscattering geometry, exhibit four new vibrational modes at 256, 314, 377 and 428 cm-1 compared with an undoped GaN sample. The modes at 377 and 428 cm-1 are attributed to gap modes related to the Ga-P bond vibrations, whereas the other two modes at 256 and 314 cm-1 are assigned to phosphorus clusters and disorder-activated scattering, respectively. The frequency of the A1 (LO) mode is found to decrease with increasing x at a much high rate of approximately 268 cm-1/x for x<0.03. This red shift is attributed to the effects of alloying and strain. Furthermore, we have not observed characterizations related to GaP resulted from the phase separation from PL, XRD and Raman spectra of all investigated GaN1-xPx samples. \u00a9 2003 Elsevier Science B.V.

The epitaxially lateral overgrowth of GaN on SiO2 areas is realized and a planar ELO GaN film is obtained. Scanning electron microscope, transmission electron microscope (TEM) and atomic force microscope (AFM) are used to study the structure and surface morphology of the ELO GaN materials. AFM images indicate that no observable step termination is detected over a 4 \u03bcm2 area in the ELO region. TEM observations indicate that the dislocation density is very low in the ELO region. No void at the coalescence interface is observed. Lattice bending as high as 3.3\u00b0 is observed and attributed to pileup of threading dislocations coming from the underlying GaN \"seeding layer\" and tilting horizontally and quenching at the coalescence interface. \u00a9 2000 Materials Research Society.",

Photoluminescence spectra for GaNi1-xPx layers with P/N composition ratios of 15%, 11% and 3% show the red-shifts of 100 meV, 78 meV and 73 meV, respectively, from that of GaN due to a large bowing of band gap energy. X-ray diffraction results show that (0002) peaks of GaNi1-xPx samples have shifted to smaller angles compared with that of an undoped GaN sample, and the linewidth of the (0002) peak becomes broader with increasing P composition in the samples, indicating that the crystal lattice distortion is produced due to the P incorporation into the GaN host lattice. No peak related to GaP is observed in X-ray diffraction and photoluminescence spectra, which indicates that the phase separation between GaN and GaP has not occurred in our GaNi1-xPx samples.",

After annealing at 850\u00b0C for 5 min, the Rc reaches as low as 1.6\u00d710-4 \u03a9\u00b7cm2. Based on the analysis of XRD measurements, it is concluded that N atoms in n-AlGaN layer diffuse out and much more N-vacancies are formed after the annealing temperatures reached 500\u00b0C and above. It induces the heavy n-type doped layer near the n-AlGaN surface, and thus, it leads to the decrease of Rc. With increasing of the annealing temperature, more N atoms in n-AlGaN layer diffuse out and react with Ti atoms. Ti2N at the interface between Au/Pt/Al/Ti and n-AlGaN is formed after annealing at 800\u00b0C, resulting in the Rc further decreasing.",

In high-frequency capacitance-voltage (C-V) measurements, the sheet concentration of the two-dimensional electron gas at the Al0.22Ga0.78N/GaN interface in the MFS structure decreases from 1.56 \u00d7 1013 cm-2 to 5.6 \u00d7 1012 cm-2 under the -10 V applied bias. A ferroelectric C-V window of 0.2 V in width near -10V bias is observed, indicating that the AlxGa1-xN/GaN MFS structure can achieve memory performance without the reversal of the ferroelectric polarization.

Diethyl gallium chloride, (C 2H 5) 2GaCl, was used in as the MOVPE Ga precursor. The lateral and vertical growth rates as well as the overgrowth morphology of ELO GaN structures are dependent on growth temperature, V/III ratio and the in-plane orientation of the mask opening. A high growth temperature and low V/III ratio increase the lateral growth rate and produce ELO structures with a planar surface to the GaN prisms. High-quality coalesced and planar ELO GaN has been fabricated by both growth chemistries. The use of the diethyl gallium chloride source allows for the benefits of HVPE growth to be realized within the MOVPE growth environment.",

        "abstract": "Influence of relaxation on the two-dimensional electron-gas (2DEG) in AlxGa1-xN/GaN/AlyGa1-yN double heterostructure (DH) is investigated by self-consistently solving the coupled Schr\u00f6dinger and Poisson equations. The GaN channel layer is in compressive strain on a relaxed AlGaN lower barrier (LB) so as to improve Al content in the AlxGa1-xN top barrier (TB) to be double that in the LB (y) and hence the 2DEG density is greatly improved. It is found that the 2DEG sheet density increases with increasing Al content in the TB and achieves a maximum Ns=3.88 \u00d7 1013cm-2 at x=0.88 (with y=0.38), even behind the onset of relaxation at x=0.76, indicating the dominant influence of polarization effect and quantum confinement effect. Further increasing x will reduce AS due to significant relaxation. Taking relaxation R into account, the 2DEG sheet density increases with increasing the Al content in the AlyGa1-yN lower barrier (LB), opposite to the case of fully strained. \u00a9 2004 IEEE.",

The effects of LN-doping on the structural and electrical properties of the BNST\u2013xLN system were systematically investigated. The results of Raman spectroscopy revealed that the substitution of LN softens the phonon vibrations in the BNST\u2013xLN system, in accordance with the remarkable reduction in the phase transition temperature (TF\u2212R), remnant polarization (Pr), negative strain (Sneg) and piezoelectric coefficient (d33). However, the degradation of the long-range ferroelectric orders was accompanied by a significant increase in the electric field\u2013induced strain response. At x\u2009=\u20090.04, a maximum unipolar strain of ~\u20090.36% with a corresponding normalized strain (Smax/Emax) of ~\u2009600\u00a0pm/V was obtained at room temperature, which should be mainly ascribed to the reversibly electric field-induced phase transition between the ergodic relaxor and ferroelectric phases due to their comparable free energies in the two-phase coexistence region. Moreover, it was also found that the BNST\u2013xLN system processes predominant electrostrictive behaviors with relatively high electrostrictive coefficient (Q33) and excellent temperature stability when the field-induced phase transition cannot be trigged by the applied electric field, as evidenced by a fact that the Q33 value of BNST\u20130.08LN ceramic keeps almost constant as high as ~\u20090.028\u00a0m4/C2 in the temperature range from room temperature to 120\u00a0\u00b0C.",

Taking the piezoelectric effect into account, the two-dimensional electron gas concentration is calculated to be as high as 1019 cm-3. To gain an understanding on how the two-dimensional electron gas distribution is influenced by dopant concentration in material, we observed the two-dimensional electron gas concentration and occupation of subbands versus doping level in GaN and in AlGaN layer. The results show that the two-dimensional electron gas concentration depends much more strongly on the doping level in AlGaN than in GaN. And besides, the heavier doping in GaN should weaken the quantum confinement in the AlGaN/GaN heterointerface. \u00a9 2001 American Institute of Physics.",

The energy gap of hexagonal GaN was determined as 3.39 and 3.400 eV by optical transmission and photoreflectance, respectively. The refractive index of GaN as a function of photon energy was drawn from the transmission spectrum. Furthermore, Raman scattering spectra were employed to study the phonon modes of the GaN film. The properties of LO phonon-plasmon coupled modes were further studied, and the carrier concentration and damping constant were determined by line-shape fitting of the coupled modes.",

The PL peak related to recombination between the two-dimensional electron gases (2DEG) and photoexcited holes is located at 3.448 eV at 40 K, which is 45 meV below the free excitons (FE) emission in GaN. The peak can be observed at temperatures as high as 80 K. The intensity of the 2DEG PL peak is enhanced significantly by incorporating a thin Al0.12Ga0.88N layer into the GaN layer near the heterointerface to suppress the diffusion of photoexcited holes. The energy separation of the 2DEG peak and the GaN FE emission decreases with increasing temperature. Meanwhile, the 2DEG peak energy increases with increasing excitation intensity. These results are attributed to the screening effect of electrons on the bending of the conduction band at the heterointerface, which becomes stronger when temperature or excitation intensity is increased. \u00a9 2000 American Institute of Physics.",

The epitaxially lateral overgrowth of GaN on SiO2 areas is realized and a planar ELO GaN film is obtained. Scanning electron microscope, transmission electron microscope (TEM) and atomic force microscope (AFM) are used to study the structure and surface morphology of the ELO GaN materials. AFM images indicate that no observable step termination is detected over a 4 \u03bcm2 area in the ELO region. TEM observations indicate that the dislocation density is very low in the ELO region. No void at the coalescence interface is observed. Lattice bending as high as 3.3\u00b0 is observed and attributed to pileup of threading dislocations coming from the underlying GaN 'seeding layer' and tilting horizontally and quenching at the coalescence interface.",

The calculated results also show that the 2DEG distribution gradually expands to the inside of the AlGaN and GaN layers with increasing temperature due to the electron transfer to the higher order subbands. Hence, the effect of screening on LO phonon scattering is weakened and the alloy scattering of the AlGaN layer on the 2DEG becomes stronger.",

Diethyl gallium chloride, (C2H5)2GaCl, was used in as the MOVPE Ga precursor. The lateral and vertical growth rates as well as the overgrowth morphology of ELO GaN structures are dependent on growth temperature, V/III ratio and the in-plane orientation of the mask opening. A high growth temperature and low V/III ratio increase the lateral growth rate and produce ELO structures with a planar surface to the GaN prisms. High-quality coalesced and planar ELO GaN has been fabricated by both growth chemistries. The use of the diethyl gallium chloride source allows for the benefits of HVPE growth to be realized within the MOVPE growth environment. \u00a9 1999 Materials Research Society.",

These structures show leakage current lower than 10-11 A at applied voltage of 5V. X-ray diffraction shows that ferroelectric Pb(Zr0.53Ti0.47)O3 films directly on GaN are well crystallized with perovskite structure. Because of the high thermal stability and relatively smaller mismatch between GaN and ferroelectrics in comparison with that of Si/ferroelectric structures, GaN looks like more promising as semiconductor active layer for metal-ferroelectric-semiconductor field effect transistors.",

The threading dislocation density in the LEO GaN is reduced by about two orders. Different etching angles of the two sidewalls of SiO2 masks (66\u00b0 and 90\u00b0) lead to the asymmetry of the LEO and cause the particular microstructures of LEO GaN. In micro-Raman spectra, the intensities vary weakly periodically about 5 \u03bcm perpendicular to the mask stripes. The indistinct selective growth in the top surface is discussed.",

Measurement of the forward bias current-voltage behavior of the device demonstrates a departure from the Shockley model of p-n diodes, and it is observed that the dominant mechanism of carrier transport across the junction is associated with carrier tunneling. Electroluminescence experiments of the devices indicates that there are an emission peak located at 2.80 eV, and a relatively weaker short-wavelength peak at 3.2 eV. A significant blue shifts of the optical emission peak which is consistent with the tunneling character of electrical characteristics was observed. Furthermore, we studied the properties of electroluminescence under various pulsed currents, and a degradation in I-V characteristics and a low resistance ohmic short were observed.",

The occupation of two subbands is observed from the Shubnikov-de Haas oscillations. It is found that the total density of the two-dimensional electron gas (2DEG) as a function of the electron sheet density in the second subband is linear. The threshold of the 2DEG density that the second subband begins to be occupied is 7.3 x 1012cm-2. The transport mobility of the 2DEG in the two subbands is obtained by using the mobility spectrum technique. It is found that the transport mobility in the first subband decreases significantly when the relaxation of the Al0.22Ga0.78N barrier occurs. The electron mobility in the second subband is much larger than that in the first one. The results indicate that the interface roughness scattering and the alloy disorder are the main mechanisms in determining the 2DEG mobility in AlxGa1-xN/GaN heterostructures.",

We obtained the detectable energy span of the device up to ultraviolet by photocurrent measurement. The spectral responsivity remained nearly constant for wavelengths from 250 to 365 nm and dropped by three orders of magnitude within 10 nm of the band edge (by 380 nm). The detector was measured to have a responsivity of 133 A/W at a wavelength of 360 nm under a 5-V bias, and the voltage-dependent responsivity was performed. Furthermore, an easy method was developed to determine the response time, and the relationship between response time and bias was obtained.",

There are two characteristic slopes in the experimental and simulated C-V curves. The influences of the polarization-induced charge density, n-AlGaN doping level and the Schottky barrier height on the positions of the two slopes in the C-V curves are much different from each other. The polarization-induced charge density can be extracted accurately by fitting the experimental C-V curves. It is extracted to be 6.78 \u00d7 1012 cm-2 in modulation-doped Al0.22Ga0.78N/GaN heterostructures with the Al0.22Ga0.78N thickness of 30 nm or 45 nm. The charge density reduces to 1.30 \u00d7 1012 cm-2 in the heterostructure with the Al0.22Ga0.78N thickness of 75 nm. It is thought that the reduction of the polarization-induced charges at the heterointerface is due to the partial relaxation of the Al0.22Ga0.78N layer on GaN.",

The Electric properties of GaN MFS structure with different oxide thickness have been characterized by high-frequency C-V measurement. When the PZT films are as thick as 1 \u03bcm, the GaN active layers can approach inversion under the bias of 15V, which can not be observed in the traditional GaN MOS structures. When the PZT films are about 100 nm, the MFS structures can approach inversion just under 5V.

In the scanning range of temperature 77 K-300 K, only one deep level could be measured. At the reverse bias of 3 V, the DLTS peak amplitude reaches a maximum, which indicates that n-In0.25Ga0.75N layer is depleted completely. With the rate window changed, this deep level was determined to position at Ec-0.24 eV. At the same time, its concentration and capture cross section were calculated as 2.2% ND and 1.93 \u00d7 10-15 cm2. In the case of GaN, other groups also reported the deep level at this position. According to our work, this deep level in n-In0.25Ga0.75N layer may be associated with the line dislocation.",

X-ray diffraction (XRD) spectra show that as the reaction proceeds, ZnAl2O4 changes from the initial (111)-oriented single crystal to poly-crystal, and then to inadequate (111) orientation. Corresponding scanning electron microscope (SEM) images indicate that the surface morphology of ZnAl2O4 transforms from uniform islands to stick structures, and then to bulgy-line structures. In addition, XRD spectra present that ZnAl2O4 prepared at low temperature is unstable at the environment of higher temperature. On the as-obtained ZnAl2O 4/\u03b1-Al2O3 substrates, GaN films were grown without any nitride buffer using light-radiation heating low-pressure MOCVD (LRH-LP-MOCVD). XRD spectra indicate that GaN film on this kind of complex substrate changes from c-axis single crystal to poly-crystal as ZnAl 2O4 layer is thickened. For the single crystal GaN, its full width at half maximum (FWHM) of X-ray rocking curve is 0.4\u00b0. Results indicate that islands on thin ZnAl2O4 layer can promote nucleation at initial stage of GaN growth, which leads to the (0001)-oriented GaN film.",

        "abstract": "We have investigated the dry oxidation behavior of an A1N epilayer on Si(111) substrate by metalorganic chemical vapor deposition (MOCVD) at different temperatures and different oxidation times through XRD analysis and scanning electron microscopy (SEM). The A1N epilayer has been completely oxidized into polycrystalline \u03b1-Al2O3 after oxidation at 1100\u00b0C for 2 h. The ratio of O2 to N2 introduced into the furnace has an influence on the structure of \u03b1-Al 2O3. There are only \u03b1-Al2O3 (104), (113) diffraction peaks in the XRD curve if the O2:N 2 is lower than 0.2:1. At the temperature over 1100\u00b0C, the oxidation is initiated with a rapid oxidation process, followed by a relatively slow process. These two oxidation stages are respectively related to the interfacial reaction mechanism and the diffusion mechanism.",

The wide-angle and small angle x-ray diffraction spectra show high crystalline quality of the sample. Optical transmission and cathodoluminescence spectra exhibit that there is a blue shift of the energy bandedge in the AlGaN/GaN double quantum wells comparing to that of bulk GaN, The experimental data are compared to theoretical calculation based on the finite square well model and a confined particle transitions are identified. The observed energy shift which differs from calculated values of ground state electron to heavy hole transition is attributed to strain in the AlGaN/GaN system. ? 1997 by Allerton Press, Inc.",

X-ray photoelectron spectroscopy and Auger electron spectroscopy were used to analyse the components and chemical structures of AlN/Si (111). The results indicated that a mix-crystal transition region, approximately 12nm, was present between the AlN film and the Si substrate and it was composed of AlN and Si3N4. After analysis we found that the existence of Si3N4 could not be avoided in the AlN/Si (111) interface because of strong diffusion at 1070\u00b0 C. Even in Ally layer Si-N bonds, Si-Si bonds can be found.",

For the GaN1-xPx alloys, there are two competitive mechanisms that influence the carrier concentration. One is from the effect of the isoelectronic traps which decrease the carrier concentration while the other is from the effect of defects which increase the carrier concentration. The calculated results of imaginary part of the reciprocal dielectric function of GaN and GaN1-xPx alloys show that the longitudinal optical phonon-plasmon (LPP) modes shift to high frequency direction and its linewidth gradually broadens with increasing carrier concentration in GaN1-xPx (indicating that the coupling of LPP modes gradually enhances and damping of LPP modes gradually augments.",

The GaN and PZT films in the MFS structures have been characterized by various methods such as photoluminescence (PL), wide-angle X-ray diffraction (XRD) and high-resolution X-ray diffraction (HRXRD). The Electric properties of GaN MFS structure with different oxide thickness have been characterized by high-frequency C-V measurement. When the PZT films are as thick as 1 \u03bcm, the GaN active layers can approach inversion under the bias of 15V, which can not be observed in the traditional GaN MOS structures. When the PZT films are about 100 nm, the MFS structures can approach inversion just under 5V. All the marked improvements of C-V behaviors in GaN MFS structures are mainly attributed to the high dielectric constant and large polarization of the ferroelectric gate oxide.",

The elastic scattering time \u03c4e, dephasing time \u03c4\u03c6 and spin-orbit scattering time \u03c4so at various temperatures are obtained. When the second subband in the triangular quantum well at the heterointerface is occupied by the 2DEG, the weak anti-localization is observed clearly, which is thought to be due to the strong spin-orbit effect induced by the intersubband scattering. The spin-orbit effect and the intersubband scattering become stronger with increasing temperature. \u00a9 2004 American Institute of Physics.",

        "abstract": "High quality Si1-x-yGexCy alloy layers were grown on Si (100) substrate by rapid thermal processing very low pressure chemical vapor deposition (RTP/VLP-CVD) using ethylene(C2H 4) as C source. The composition of Si1-x-yGe xCy allow layers were measured by Auger Electron Spectroscopy (AES). The C incorporation mode was characterized by Fourier transform infrared spectroscopy (FTIR). The content of substitutional C in Si1-x-yGexCy alloy layers was calculated from the local vibration mode (LVM) of Si-C bond in FTIR spectroscopy. It was found that the lower temperature and higher SiH4/C2H 4 flow ratio are helpful in forming the substitutional C and improving the crystal quality. The mechanism responsible for C incorporation in Si1-x-yGexCy alloy layer grown by RTP/VLP-CVD using C2H4 was explained by the reaction between SiH 4 and C2H4 at different growth temperature.",

It is found that oxygen precipitation is not influenced by Cu impurities, but enhanced significantly by Fe impurities even if the concentration of fe is much lower than that of Cu in Si. Cu forms precipitate colonies of a low density and a big size, and does not react with minute oxygen precipitates existing in as-grown specimens. Contrarily, Fe precipitates on them and forms Fe decorated silica particles of a very high density, which serve as the efficient sites for the nucleation of oxygen precipitates.",

The epitaxially lateral overgrowth of GaN on SiO 2 areas is realized and a planar ELO GaN film is obtained. Scanning electron microscope, transmission electron microscope (TEM) and atomic force microscope (AFM) are used to study the structure and surface morphology of the ELO GaN materials. AFM images indicate that no observable step termination is detected over a 4 \u03bcm 2 area in the ELO region. TEM observations indicate that the dislocation density is very low in the ELO region. No void at the coalescence interface is observed. Lattice bending as high as 3.3\u00b0 is observed and attributed to pileup of threading dislocations coming from the underlying GaN \"seeding layer\" and tilting horizontally and quenching at the coalescence interface.",

Compared to the Si3 N4 and Si O2 passivation dielectrics, the AlN film led to an obvious increase not only in carrier concentration but also in mobility of the 2DEG. The variation of the carrier concentration with temperature in the AlN passivated sample is also smaller in comparison with the Si3 N4 passivated sample. These indicate that the AlN film is a promising passivation dielectric. In addition, the results from Hall and high-resolution x-ray diffraction measurements show that the change of strain after passivation contributes only in a relatively small proportion to the variation of the carrier concentration in AlGaNGaN heterostructures. \u00a9 2006 American Institute of Physics.",

The peak value of the 2DEG concentration occurs at 1.3 nm beneath the heterointerface. The full width at half maximum (FWHM) of the 2DEG peak is 2.3 nm and the sheet density of the 2DEG is 6.5\u00d71012cm-2. The sheet density of the 2DEG is one order higher and the FWHM is one order lower than those in AlxGa1-xAs/GaAs heterostructures because of the piezoelectrically induced polarization field in the order of-MV/cm, which will strongly modulate the conduction-band of AlxGa1-xN/GaN heterostructure as well as the much larger conduction band discontinuity in the AlxGa1-xN/GaN heterointerface.",

By means of the measurements based on the transmission line model, the \u03c1C as low as 1.6\u00d710-4 \u03a9cm2 is obtained. Based on the X-ray diffraction analysis, it is found that N atoms in n-AlGaN layer diffuse out and a much amounts of N-vacancies are formed in n-AlGaN layer near the interface after the sample is annealed at temperatures higher than 500 \u00b0C. It induces the heavy n-type doped region in n-AlGaN near the interface, and thus leads to the decrease of the \u03c1C. With increasing the annealing temperature, more N atoms in n-AlGaN layer diffuse out and react with Ti atoms. Ti2N phase is formed at the interface after the sample is annealed at 800 \u00b0C. In this case, the \u03c1C further decreases. \u00a9 2003 Elsevier Science B.V. All rights reserved.",

The 1-\u03bcm-thick GaN epilayers grown on (0001) sapphire substrates by Rapid-Thermal-Processing/Low Pressure Metalorganic Chemical Vapor Deposition were used in this work. The oxidation of GaN in dry oxygen was performed at various temperatures for different time. The oxide was identified as the monoclinic \u03b2-Ga2O3 by a \u03b8-2\u03b8 scan X-ray diffraction (XRD). The scanning electron microscope observation shows a rough oxide surface and an expansion of the volume. XRD data also showed that the oxidation of GaN began to occur at 800\u00b0C. The GaN diffraction peaks disappeared at 1050\u00b0C for 4 h or at 1100\u00b0C for 1 h, which indicates that the GaN epilayers has been completely oxidized. From these results, it was found that the oxidation of GaN in dry oxygen was not layer-by-layer and limited by the interfacial reaction and diffusion mechanism at different temperatures.",

The elastic scattering time \u03c8e, dephasing time \u03c8 and spin-orbit(s-o) scattering time TSO at various temperatures are obtained. When the second subband in the triangular quantum well at the heterointerface is occupied by the 2DEG, the anti-weak localization is observed clearly, which is due to the strong spin-orbit interaction. The spin-orbit effect dominates the quantum correction of the conductivity in the upper subband. The intersubband scattering becomes stronger with increasing temperature.",

        "abstract": "One-step growth of GaN films on ZnAl2O4/\u03b1-Al2O3 substrates by metallorganic chemical vapor deposition (MOCVD) was investigated. ZnO films were directly deposited on \u03b1-Al2O3 by pulsed laser deposition, and ZnAl2O4 layers were synthesized by annealing ZnO/\u03b1-Al2O3 wafers at 1100\u00b0C. GaN films were then grown on these combined substrates by light-radiation heating low-pressure MOCVD. X-ray diffraction pattern of ZnAl2O4/\u03b1-Al2O3 shows the peaks of ZnAl2O4 (111). When the annealing time during ZnAl2O4 formation increases from less than 30 min to 20 h, the morphology of ZnAl2O4 surface changes from uniform islands to bulgy-line structures, while the structure of corresponding GaN films deposited on these substrates changes from c-axis single crystal to polycrystalline. The results indicate that islands on thin ZnAl2O4 layer can promote nucleation at the initial stage of GaN growth, so as to increase the quality of GaN film.",

Depth profiles of the elements indicate that the maximum P/N composition ratio is about 17% and a uniform distribution of the P atoms in the alloys is achieved. 2\u03b8/\u03c9 XRD spectra demonstrate that the (0 0 0 2) peak of the GaN1-xPx alloys shifts to smaller angle with increasing P composition. From the photoluminescence (PL) spectra, the red shifts to the bandedge emission of GaN are determined to be 73, 78, 100 and 87 meV for the GaN1-xPx alloys with the P/N composition ratios of 3%, 11%, 15% and 17%, respectively. No PL peak related to GaP is observed, indicating that the phase separation between GaN and GaP is well suppressed in our GaN1-xPx samples. \u00a9 2003 Elsevier Science B.V. All rights reserved.",

        "abstract": "Polarization-induced charges in modulation-doped Al0.22Ga0.78N/GaN heterostructures were investigated by the capacitance-voltage (C-V) method. The C-V profile of the Pt/Al0.22Ga0.78N/GaN Schottky diodes with various Al0.22Ga0.78N thicknesses shows significant differences due to change of the polarization field in the heterostructures. A numerical simulation based on the experimental results indicates that the sheet density of the polarization-induced charges at the heterointerface is 6.78 \u00d7 1012 cm-2 in the samples with the Al0.22Ga0.78N thicknesses of 30 nm or 45 nm. The charge density reduces to 1.30 \u00d7 1012 cm-2 in the sample with the Al0.22Ga0.78N thickness of 75 nm. It is thought that the reduction of the polarization-induced charges at the heterointerface is due to the partial relaxation of the Al0.22Ga0.78N layer on GaN. This work provides a technique for quantitative characterization of the polarization-induced charges in AlxGa1-xN/GaN heterostructures.",

After passivating, an additional in-plane tensile strain and an initial increase of the residual tensile strain with increasing temperature were observed in Al0.22 Ga0.78 N layers, and at higher temperatures the residual tensile strain only decreases slightly in the 100-nm-thick Al0.22 Ga0.78 N layer, but a pronounced strain relaxation occurs in the 50-nm-thick one.

The photocurrent responses of these structures were measured and analysed. The multilayer structures showed a high response in a narrow range of wavelengths. The peak wavelength is located at 365 nm at which the responsivity is as high as 24A/W under 5.5 V bias; this is much higher than the GaN monolayer structure. This high responsivity results mainly from the high polarization electric field in the GaN layer of the Al 0.2Ga 0.8N/GaN/Al 0.2Ga 0.8N heterostructure. \u00a9 2001 Chinese Physical Society and IOP Publishing Ltd.",

        "abstract": "Both Raman and infrared reflection spectra for a series of high P compositional GaN1-xPx alloys grown by means of light-radiation heating, low-pressure metal-organic chemical vapor deposition are investigated. The Raman spectra of GaN1-xPx alloys, recorded in backscattering geometry, exhibit four new vibrational modes at 256, 314, 377, and 428 cm-1 compared with an undoped GaN sample. Those modes are assigned to the so called quasi-local mode induced by P in GaN, disorder-activated scattering and gap modes related to the Ga-P bond vibrations, respectively. The frequency of the A1(LO) mode is found to redshift, which is attributed to the effects of alloying and strain. The infrared reflectance spectra show another new mode near 630 cm-1, which is associated with the E2(TO) phonon mode that results from a random distribution of the P atoms in GaN1-xPx alloys and elimination of lattice translational symmetry.",

The density and the size of GaN dots are determined by using an atomic force microscope (AFM), and they are controllable by changing the temperature and the duration of the depositing and the annealing. GaN dots are formed only after annealing at high temperature. The phenomenon can be explained like this: the initial layer deposited at 500 \u00b0C is a high energy intermediate phase in which the large strain energy can not be relaxed because of the low temperature depositing.",

It has been found that carrier gas flow rate produces a significant effect on both pre-reactions and the quality of the films. Both (10-11) and (11-20) peaks of the X-ray diffraction (XRD) spectra and the relevant yellow luminescence (YL) of the photoluminescence (PL) spectrum as well as the impurity states close to the band edge were respectively observed upon lowing the N2 flow rate. The quality of the samples was improved with the increase of carrier gas flow rate. The correlation of structural and optical properties of the GaN films manifested a close relation of deep level yellow luminescence to non-c planes developed during the growth. It was speculated that the emission of YL is probably due to the formation of deep gap slate in the band gap resulting from the complex of Ga vacancy and impurities trapped at (10-11) and (11-20) atomic facets.",

The l-jim-thick GaN epilayers grown on (0001) sapphire substrates by Rapid-Thermal-Processing/Low Pressure Metalorganic Chemical Vapor Deposition were used in this work. The oxidation of GaN in dry oxygen was performed at various temperatures for different time. The oxide was identified as the monoclinic \u03b2-Ga-4C-4 by a 6-26 scan X-ray diffraction (XRD). The scanning electron microscope observation shows a rough oxide surface and an expansion of the volume. XRD data also showed that the oxidation of GaN began to occur at 800\u00b0C. The GaN diffraction peaks disappeared at 1050\u00b0C for 4 h or at 1100\u00b0C for 1 h, which indicates that the GaN epilayers has been completely oxidized. From these results, it was found that the oxidation of GaN in dry oxygen was not layer-by-layer and limited by the interfacial reaction and diffusion mechanism at different temperatures. \u00a9 2000 Materials Research Society.",

The energy gap of hexagonal GaN is determined as 3.39 and 3.400eV by optical transmission and 488nm Ar+ laser excited photoreflectance, respectively, and refractive index of GaN film as the function of photon energy is obtained. The possible origin of the PR signal is attributed to the modulation of the surface field and lineshape broadening of defects. Raman scattering spectra are employed to investigate the photon modes of the GaN film. The properties of LO phonon-plasmon coupled modes are further studied, and the carrier concentration and damping constant are determined by line-shape fitting of the coupled modes.",

Measurement of the forward bias current-voltage behavior of the device demonstrates a departure from the Shockley model of p-n diodes, and it is observed that the dominant mechanism of carrier transport across the junction is associated with carrier tunneling. Electroluminescence experiments of the devices were performed. We obtained an emission peak located at 2.80 eV, and a relatively weaker short-wavelength peak of 3.2 eV. A significant blue shifts of the optical emission peak which is consistent with the tunneling character of electrical characteristics was observed. Furthermore, we studied the properties of electroluminescence under various pulsed currents, and a degradation in I-V characteristics and a low resistance ohmic short were observed.",

        "abstract": "A metal-ferroelectric-semiconductor (MFS) structure has been developed by depositing SrBi2Ta2O9 (SBT) films directly on n-type (100) Si by pulsed laser deposition. In the MFS structure, evidence for ferroelectric border traps in the SBT film has been obtained by high-frequency capacitance-voltage (C-V) measurement. When the ramp rate of voltage is higher than 200 mV/s, typical ferroelectric C-V hysteresis loops with the counterclockwise direction are obtained in C-V plots. When the ramp rate is lower than 80 mV/s, the ferroelectric hysteresis loops are replaced by the trap-induced ones with the clockwise direction. This pronounced change results from the fact that more and more border traps in SBT can communicate with the underlying Si. The border-trap density at the ramp rate of 10 mV/s is as high as 1.8\u00d71012 cm-2. Moreover, the width of the hysteresis loops changes linearly with the logarithmic decrease in ramp rate, which is consistent with the ferroelectric border traps communicating with Si by tunneling or a thermally activated process. \u00a9 2000 American Institute of Physics.",

The SiO2 films are grown by plasma-enhanced chemical vapor deposition. High-frequency C-V characteristics show the agreement of the measured C-V curve of SiO2/n-GaN with an ideal curve in deep depletion and the very small hysteresis, which indicates that the interface traps concentration in the sample is low. However, for SiO2/GaN/Al0.4Ga0.6N/GaN, the measured C-V curves show a notable flat-band shift of about 9.2 V and typical polarization hysteresis window. These show the influence of the polarization charges in this structure. The capacitance on SiO2/GaN/Al0.4Ga0.6N/GaN reaches a minimum value under around -5V bias. The saturation at a minimum value of the C-V curve indicates the presence of holes accumulation in the MIS structure. These results imply that the piezoelectric effect in GaN/Al0.4Ga0.6N/GaN play an important role for the formation of the p-channel.",

From our results, the critical thickness of an Al0.22Ga0.78N layer on GaN is estimated to be between 65 and 75 nm, which is much higher than that predicted by theoretical calculation.

        "abstract": "Polarization-induced charge density in modulation-doped Alx Ga1-x N/GaN heterostructures is extracted through the simulation of the Schottky Capacitance-Voltage (C-V) characteristics. C-V measurements were made on Pt Schottky contacts on modulation-doped Al0.22Ga0.78 N/GaN heterostructures. The C-V characteristics were simulated numerically using the three-dimensional Fermi model. Influence of sample parameters on C-V characteristics is analized by the simulation. Polarization-induced charge density, n-AlGaN doping level and Schottky barrier height have different influences on the C-V characteristics, and thus the polarization-induced charge density can be extracted accurately. The polarization-induced sheet charge density at the heterointerface is extracted to be 6.78 \u00d7 1012 cm-2 in the Al0.22 Ga0.78 N/GaN heterostructure with the Al0.22 Ga0.78 N thickness of 45nm. This work provides a method for quantitative analysis of the polarization-indeced charge in modulation-doped AlxGa1-x N/GaN heterostructures.",

        "abstract": "Transport properties of the two-dimensional electron gas (2DEG) in AlxGa1-xN/GaN heterostructures were investigated by means of magnetotransport measurements. The mobilities corresponding to the 2DEG in the first and the second subbands in the trianglar quantum well at the heterointerface were obtained. When the AlxGa1-xN barrier is partially relaxed, the mobility of the 2DEG in the first subband decreases significantly, but there is an increase of mobility in the second subband. We suggest that the scattering from the piezoelectric polarization field modulated by the misfit dislocations at the heterointerface is responsible for the decrease of the 2DEG mobility. Meanwhile, the 2DEG in the second subband leaves farther from the heterointerface than that in the first subband, and thus suffers weaker scattering from the heterointerface roughness and the modulated polarization field. Therefore, the mobility of the 2DEG in the second subband is much higher than that in the first subband. \u00a9 2003 Elsevier Science B.V. All rights reserved.",

When the density of the threading dislocation (TD) increases about one order of magnitude, the yellow luminescence (YL) intensity is strengthened from negligible to two orders of magnitude higher than the band edge emission intensity. The full width of half maximum (FWHM) of the GaN (0002) peak of the XRD rocking curve was widened from 11 min to 15 min, and in Raman spectra, the width of E2 mode is broadened from 5 cm-1 to 7 cm-1. A \"zippers\" structure at the interface of GaN/sapphire was observed by high-resolution electron microscope (HREM). Furthermore the origins of TD and relationship between physical properties and microstructures combining the growth conditions are discussed.",

The GaN and PZT films in the MFS structures have been characterized by various methods such as photoluminescence (PL), wide-angle X-ray diffraction (XRD) and high-resolution X-ray diffraction (HRXRD). The Electric properties of GaN MFS structure with different oxide thickness have been characterized by high-frequency C-V measurement. When the PZT films are as thick as 1 \u03bcm, the GaN active layers can approach inversion under the bias of 15V, which can not be observed in the traditional GaN MOS structures. When the PZT films are about 100 nm, the MFS structures can approach inversion just under 5V. All the marked improvements of C-V behaviors in GaN MFS structures are mainly attributed to the high dielectric constant and large polarization of the ferroelectric gate oxide.",

The inter-subband scattering of the two-dimensional electron gas was observed. The inter-subband scattering is very weak and depends weakly on temperature when temperature is between 1.3 K and 10 K and becomes stronger with increasing temperature when temperature is higher than 10 K. The strain relaxation of the Al0.22Ga0.78N layer influences the inter-subband scattering. It is suggested that the inter-subband scattering is dominant by the elastic scattering when temperature is lower than 10 K, and changes to be dominant by the inelastic scattering of the acoustic phonons when temperature is higher than 10 K.",

        "abstract": "High quality GaN layers were grown on Si(1 1 1) substrates using high-temperature-grown AlN as buffer layer by rapid thermal process low-pressure metalorganic chemical vapor deposition. The growth and characteristics of AlN buffer layer and the GaN layers were investigated by using scanning electron microscope, X-ray diffraction, photoluminescence (PL), Raman scattering, and Hall measurements at room temperature. It was found that pre-seeding Al to Si surface is a critical condition for AlN growth on Si. Two-dimensional growth of AlN was achieved under optimized conditions. Raman scattering shows a narrow GaN E2 peak and broad AlN E2, E1 peaks. At room temperature, the investigated films are unintentionally doped n-type. The carrier concentration is about 1.3 \u00d7 1017 cm-3 and the Hall mobility is about 210 cm2/V s. Metal-semiconductor-metal photoconductive detectors were fabricated on the GaN/Si(1 1 1) films. These detectors show a sharp cut-off wavelength at 363 nm. A maximum responsivity of 6.9 A/W was achieved at 357 nm under a 5.0 V bias. These results indicate that high quality GaN films on Si(1 1 1) can be obtained using the AlN buffer layer, and the potential application of GaN films based on Si substrates. \u00a9 2001 Published by Elsevier Science B.V.",

The mobility of the two-dimensional electron gas (2DEG) at the heterointerfaces is much higher than that of the electrons in GaN films at both 300 and 77 K.

        "abstract": "Photoluminescence (PL) of modulation-doped Al0.22Ga0.78N/GaN heterostructures was investigated. The PL peak related to recombination between the two-dimensional electron gases (2DEG) and photoexcited holes is located at 3.448 eV at 40 K, which is 45 meV below the free excitons (FE) emission in GaN. The peak can be observed at temperatures as high as 80 K. The intensity of the 2DEG PL peak is enhanced significantly by incorporating a thin Al0.12Ga0.88N layer into the GaN layer near the heterointerface to suppress the diffusion of photoexcited holes. The energy separation of the 2DEG peak and the GaN FE emission decreases with increasing temperature. Meanwhile, the 2DEG peak energy increases with increasing excitation intensity. These results are attributed to the screening effect of electrons on the bending of the conduction band at the heterointerface, which becomes stronger when temperature or excitation intensity is increased.",

The result is attributed to the control of polarity of GaN films during growth. The additional HCl altered the equilibrium at the GaN growth front, and the reversible reaction decreased the nucleation density or growth rate. Further, lower growth rate promote the surface diffusion and the coalescence over (0001) plane. Additional HCl may improve the surface morphology by suppressing the (000-1) polarity growth in the initial stage of the growth.",

Two different types of behaviour of noising centres, Coulomb-attractive and Coulomb-repulsive centres, have been observed. By studying the gate bias and temperature dependence of the transition time and amplitude of the RTSs caused by the noising centres, it has been demonstrated experimentally that a thermally activated process may dominate for Coulomb-repulsive centres, while quantum mechanical tunneling is a favoured process for Coulomb-attractive centres. In particular, RTSs with very large amplitude (>60%), which are almost independent of measurement temperature and gate bias, are observed in an ultra-narrow channel, which is well described by the quantum tunneling model.",

The deposition temperature is 950\u00b0C, about 100\u00b0C lower than that in normal rf-heating MOCVD growth. The FWHM of GaN (0002) peak of the X-ray diffraction rocking curve is 8.7 arc min. Photoluminescence spectrum of GaN film shows that there is a very strong band-edge emission and no 'yellow-band' luminescence. Hall measurement indicates that the n-type background carrier concentration of GaN film is 1.7 \u00d7 1018 cm-3 and the Hall mobility of it is 121.5 cm2/V s. It is suggested that the radiation of light in GaN growth enhances the dissociation of ammonia and decreases the disadvantages of the parasite reaction between trimethylgallium and ammonia.",

The films studied were grown by metal organic chemical vapor deposition (MOCVD), with Mn implanted in 150 KeV, which can offer many distinguished advantages compared with other doping methods. A new energy band with a minimum at 2.9 eV in the reflectance spectra has been observed. The yellow band emission was greatly decreased according to the result of photoluminescence. The structure analysis revealed that the Mn doped sample has good crystal quality as the pure GaN after annealed. And further discussions on the role of Mn in GaN: Mn films have been presented.",

Numerical fittings based on the experimental data indicate that there are surface states with high density locating on the Al x-Ga 1-xN barrier. The density of the surface states is about 10 12 cm -2eV -1, and the time constant is about 1 \u03bcs.

When the density of the threading dislocation (TD) increases about one order of magnitude, the yellow luminescence (YL) intensity is strengthened from negligible to two orders of magnitude higher than the band edge emission intensity. The full width of half maximum (FWHM) of the GaN (0002) peak of the XRD rocking curve was widened from 11 min to 15 min, and in Raman spectra, the width of E2 mode is broadened from 5 cm-1 to 7 cm-1. A 'zippers' structure at the interface of GaN/sapphire was observed by high-resolution electron microscope (HREM). Furthermore the origins of TD and relationship between physical properties and microstructures combining the growth conditions are discussed.",

Owing to the advantages of a compound potential well and a higher offset in the valence band, this kind of memory can possess the advantages of both high-speed programming and long retention simultaneously, and thus it has the well storage characteristics. Furthermore, a 2\u00d72 logical array is used to illustrate the principle of logical. Therefore, this kind of device, as an excellent nonvolatile memory operating at room temperature, is desired for the applications in the future VLSI.",

The 1-\u03bcm-thick GaN epilayers grown on (0001) sapphire substrates by Rapid-Thermal-Processing/Low Pressure Metalorganic Chemical Vapor Deposition were used in this work. The oxidation of GaN in dry oxygen was performed at various temperatures for different time. The oxide was identified as the monoclinic \u03b2-Ga 2O 3 by a \u03b8-2\u03b8 scan X-ray diffraction (XRD). The scanning electron microscope observation shows a rough oxide surface and an expansion of the volume. XRD data also showed that the oxidation of GaN began to occur at 800\u00b0C. The GaN diffraction peaks disappeared at 1050\u00b0C for 4 h or at 1100\u00b0C for 1 h, which indicates that the GaN epilayers has been completely oxidized. From these results, it was found that the oxidation of GaN in dry oxygen was not layer-by-layer and limited by the interfacial reaction and diffusion mechanism at different temperatures.",

By solving the coupled Schr\u00f6dinger and Poisson equations self-consistently, we investigate the two-dimensional electron gas (2DEG) distributions and sheet densities in AlxGa1-xN/GaN DHs. Comparing to the 2DEG in Al0.5Ga0.5N/GaN single heterostructure (SH), the 2DEG sheet density in a comparable AlN/GaN/Al 0.5GaasN DH is nearly doubled from 2.31\u00d71013cm -3 to 4.47\u00d71013cm-3, mainly owing to the additional piezoelectric polarization in the GaN QW. It is also shown that 2DEG in the GaN QW is increased with increasing the Al content of the top barrier due to the stronger polarization effect and large conduction band offset at the AlxGa1-xN/GaN interface. Increasing the lower barrier thickness will reduce the 2DEG density in the GaN QW while the 2DEG at the lower AlyGa1-yN/GaN interface is increased, making the total 2DEG density almost a constant.",

The decay curves of photoconductivity are obtained by YAG: Nd pulse laser. They are characterized by two special regions, including the beginning decay region and tail region corresponding to two time constants (\u03c401-0.1 ms and \u03c402-1.0 ms). With the same light intensity and voltage, when the sample is heated to 300 \u00b0C, the time constants are both reduced. It shows that there are a large number of traps near the conduction band in the band gap. We use a model which involved two trap-levels to explain the experiment results. The model can explain the two constants of the decay curves as well as the configuration of the curves during first 200 ns. Moreover, the curves varying with the light intensity are also explained by the model.",

The deposition temperature of the LT-GaN layers is changed from 400 to 900\u00b0 C. When the LT-GaN layer is deposited at 600\u00b0C, GaN films show only c-oriented GaN (0002) and have the band edge emission at 365 nm with no yellow luminescence bands. The results indicate that the LT-GaN layer can effectively block the unexpected Si etching by reactive gas during the GaN growth. However, the surface roughness of these GaN films grown on Si(111) is larger than that of GaN films on c-plane sapphire.",

And precise control of the growth in polar direction is necessary to obtain low defect density materials as well as a specular surface. In this study, we obtained high quality GaN with smooth surface on sapphire by adding the additional HCl into the HVPE growth process. The result is attributed to the control of polarity of GaN films during growth. The additional HCl altered the equilibrium at the GaN growth front, and the reversible reaction decreased the nucleation density or growth rate. Further, lower growth rate promoted the surface diffusion and the coalescence over (0001) plane. Probably additional HCl improved the surface morphology by suppressing the (000-1) polarity growth in the initial stage of the growth.",

X-ray diffraction spectra show that the (0002) peak of GaN1-xP x shifts to smaller angle with increasing P composition and the GaN1-xPx films are still of a typical hexagonal structure. The Raman spectra of GaN1-xPx films, recorded in backscattering geometry, exhibit four new vibrational modes at 256, 314, 377 and 428 cm-1 compared with an undoped GaN sample. Those modes are assigned to the so called quasi-local mode induced by P in GaN, disorder-activated scattering and gap modes related to the Ga-P bond vibrations, respectively.",

It is found that although the two wells have the same width and the same depth the polarization-induced potential drop leads to the asymmetric potential profile of the AlxGa1-xN/GaN DQWs, The polarization-induced Stark shift leads to the drastic change of the relative location between the even and the odd order subband levels, and thus resulting in the asymmetric distribution of the electron in the two wells. \u00a9 2004 IEEE.",

On the as-obtained ZnAl2O4/\u03b1-Al2O3 substrates, GaN films were grown without any nitride buffer using light-radiation heating low-pressure MOCVD (LRH-LP-MOCVD).\n XRD spectra indicate that GaN film on this kind of complex substrate changes fromc-axis single crystal to poly-crystal as ZnAl2O4 layer is thickened. For the single crystal GaN, its full width at half maximum (FWHM) of X-ray rocking curve is 0.4\u00b0.

The quantum scattering time related to the first and the second subbands is determined to be 0.078 ps and 0.088 ps, respectively, at 1.5 K. Results indicate that the scatterings from heterointerface and ionized donors at both side of GaN well are all important in limiting quantum scattering time. By using mobility spectrum technique the transport scattering time related to the first subband is determined to be 0.128 ps. Transport-to-quantum scattering time ratio in the first subband is 1.6. It is concluded the large angle scatterings play a very important role in limiting quantum scattering time in this SQW.",

        "abstract": "The deposition and crystallization of amorphous GaN buffer layers on Si(1 1 1) is firstly investigated by using an atomic force microscope (AFM), X-ray diffraction (XRD) and a high-resolution transmission electron microscope (HRTEM). The amorphous GaN layers were deposited by MOCVD at 300 \u00b0C. The islanding process by annealing at higher temperatures has been revealed by AFM. It is found that the amorphous layers begin to be crystallized by solid-phase epitaxy at 500 \u00b0C in MOCVD, and the full-developed islands formed at about 600 \u00b0C. XRD data show that the GaN peak appeared only after an annealing at higher temperatures. Cross-sectional HRTEM micrographs of the buffer region of the samples with amorphous GaN buffer layers reveal that many domains exist in the GaN buffer layers and these domains misorientate each other with a small angle. The boundaries between domains locate near the bunched steps, and, the films on a terrace between steps have the same crystal orientation. The amorphous buffer layer deposited at 300 \u00b0C and the buffer layer directly deposited at 550 \u00b0C are used in the growth of GaN epilayers, respectively. The XRD results and photoluminescence at room temperature of such GaN epilayers show that using the amorphous GaN buffer layer lead to monocrystalline and a narrower full-width at half-maximum (FWHM) of near band emission (16 nm) than using the buffer layer directly deposited at 550 \u00b0C (FWHM of 21 nm). These results indicate that the quality of GaN epilayer on Si(1 1 1) can be improved by using the amorphous GaN buffer layer.",

        "abstract": "In this paper, the interface structure of GaN/\u03b1-Al2O3 (0 0 0 1) is studied by high-resolution transmission electron microscopy on tilted samples around the \u3008112\u03040\u3009Al2O3 axis. Sets of moir\u00e9 fringes are observed. There are many disparities, such as contrast, period, tilt angle, and so on, among these moir\u00e9 fringes located in different regions. These fringes represent magnifying images of the plane distances of (1 1\u0304 0 0)GaN and the tilts of c-axis of GaN crystallites to that of the substrate. According to these results, the growth mechanism of GaN buffer layer at the interface is discussed. \u00a9 2002 Elsevier Science B.V. All rights reserved.",

        "abstract": "Shubnikov-de Haas (SdH) measurements are performed over a temperature range of 1.5-20 K in Al0.22Ga0.78N/GaN heterostructures with two subbands occupied. In addition to an intermodulation between two sets of SdH oscillations from the first and second subbands, a beating in oscillatory magnetoresistance at 12K is observed, due to the mixing of the first subband SdH oscillations and 'magnetointersubband' (MIS) oscillations. A phase shift of \u03c0 between the SdH and MIS oscillations is also clearly identified. Our experimental results, i.e. that the SdH oscillations dominate at low temperature and MIS oscillations dominate at high temperature, fully comply with the expected behaviour of MIS oscillations.",

We obtained the detectable energy span of the device up to ultraviolet by photocurrent measurement. The spectral responsivity remained nearly constant for wavelengths from 250 to 365 nm and dropped by three orders of magnitude within 10 run of the band edge (by 380 nm). The detector was measured to have a responsivity of 133 A/W at a wavelength of 360 nm under a 5-V bias, and the voltage-dependent responsivity was performed. Furthermore, an easy method was developed to determine the response time and the relationship between response time and bias was obtained.",

The weak localization and magnetointersubband scattering effects have been studied. The measurements show that the inelastic scattering time is inversely proportional to the temperature, following the prediction by weak localization theory. Furthermore, fitting the inelastic scattering time indicates an enhanced phase-breaking rate compared to the theoretical predication. At the same time, a magnetoresistance oscillation induced by intersubband scattering has also been observed. This magnetoresistance oscillation persists to a relatively high temperature in contrast to the Shubnikov-de Haas oscillation.",

The GaN channel layer is in compressive strain on a relaxed AlGaN lower barrier (LB) so as to improve the Al content in the AlxGa1-xN top barrier (TB) to be double that in the LB (y) and hence the 2DEG density is greatly improved. It is found that the 2DEG sheet density increases with increasing Al content in the TB and achieves a maximum NS=3.88\u00d71013 cm-2 at x=0.88 (with y=0.38), even behind the onset of relaxation at x=0.76, indicating the dominant influence of the polarization effect and the quantum confinement effect. Further increasing x reduces NS due to significant relaxation. Taking relaxation, R, into account, the 2DEG sheet density increases with increasing Al content in the AlyGa1-yN lower barrier (LB), opposite to the case of fully strained.",

        "abstract": "Dendrobium plants are used commonly as tonic herbs and health food in many Asian countries, especially in China. Here we report the genetic map construction of two Dendrobium species with a double pseudo-testcross strategy using random amplified polymorphic DNA (RAPD) and sequence-related amplified polymorphism (SRAP) markers. A F(1) mapping population of 90 individuals was developed from a cross between D. officinale and D. hercoglossum. A total of 307 markers, including 209 RAPD and 98 SRAP, were identified and used for genetic linkage group (LG) analysis. The D. officinale linkage map consisted of 11 major linkage groups and 3 doublets, which covered 629.4 cM by a total of 62 markers with an average locus distance of 11.2 cM between two adjacent markers. The D. hercoglossum linkage map contained 112 markers mapped on 15 major and 4 minor linkage groups, spanning a total length of 1,304.6 cM with an average distance of 11.6 cM between two adjacent markers. The maps constructed in this study covered 92.7% and 82.7% of the D. hercoglossum and D. officinale genomes respectively, providing an important basis for the mapping of horticultural and medicinal traits and for the application of marker-assisted selection in Dendrobium breeding program.",

The results showed that at the early stage of milk filling, the grains of fully milk filling under high temperature had a higher chalkiness, lower transparency, and lower rate of white rice. Compared with the grain of early-rice, that of late rice had higher gel consistency and transparency, and higher rate of white rice. Planting rice at early-or late season had no significant effect on the amylose and protein contents of rice grain. Leaf-cutting to limit source decreased grain quality markedly, while grain-thinning to decrease sink improved grain quality significantly.",

        "abstract": "In non-climacteric fruits, the respiratory increase is absent and no phytohormone is appearing to be critical for their ripening process. They must remain on the parent plant to enable full ripening and be picked at or near the fully ripe stage to obtain the best eating quality. However, huge losses often occur for their quick post-harvest senescence. To understanding the complex mechanism of non-climacteric fruits post-harvest senescence, we constructed two small RNA libraries and one degradome from strawberry fruit stored at 20\u00b0C for 0 and 24 h. A total of 88 known and 1224 new candidate miRNAs, and 103 targets cleaved by 19 known miRNAs families and 55 new candidatemiRNAs were obtained. These targets were associated with development, metabolism, defense response, signaling transduction and transcriptional regulation. Among them, 14 targets, including NAC transcription factor, Auxin response factors (ARF) and Myb transcription factors, cleaved by 6 known miRNA families and 6 predicted candidates, were found to be involved in regulating fruit senescence. The present study provided valuable information for understanding the quick senescence of strawberry fruit, and offered a foundation for studying the miRNA-mediated senescence of non-climacteric fruits.",

QTL conditioning flag leave angle (FLA) and other four grain yield traits were determined at the one-locus level. Seventeen QTL were detected to have significant additive effects for these traits. General contributions to the phenotypic variance were between 3.46%~25.64%. QTL conditioning the all five traits were detected on chromosome 1,of which two were for FLA; each QTL were detected on chromosome 2\u30013\u30019\u300110and 11,respectively; three QTL for FLA\u3001total number of spikelets per panicle (TNSP) and number of filled grain per panicle (NFGP) respectively were detected on chromosome 5; one QTL for NFGP and two QTL for grain weight per panicle (GWP) were detected on chromosome 6.Correlation analysis revealed that flag leave angle increased grain yield by increasing spikelet fertility.",

        "abstract": "To make an genetic analysis of starch branching enzyme (Q enzyme) inheritance, which is important in catalyzing the formation of amylopectin and thereby raising the amylopectin/amylose ratio of starch in rice grains, a linkage map of 207 DNA markers were constructed by using 247 recombinant inbred lines derived from an indica-indica rice cross Zhenshan 97B/Milyang46. In 2002 and 2003, the activities of starch branching enzyme of the parents and 247 RILs were measured 10 d and 20 d respectively after flowering (Table 1). A total of 3 quantitative trait loci (QTLs) were detected to have significant additive effects on Q enzyme activities 10 d after flowering with 10% phenotypic variations explained for the three QTLs (Table 2, Fig.1). Meanwhile, qQ10-6 with significant QTL x environment interaction was detected. Epistasis analysis detected 5 and 2 significant additive-by-additive interactions for Q enzyme 10 d and 20 d respectively after flowering (Table 3), and three pairs of QTLs 10 d after flowering with significant epistasis x environment interactions were detected, explaining 3% to 12% of the phenotypic variation. The results showed that the environmental factors had obvious effect on the gene expression of Q enzyme activity in rice grain. Meanwhile, the location of qQ10-6 in relation to that of QTLs for gelatinization temperature, gene loci involved in ADPG pyrophosphorylase and soluble starch synthase were discussed with the help of a genetic map.",

        "abstract": "Grain production of rice (Oryza sativa L.) is a top priority in ensuring food security for human beings. One of the approaches to increase yield is to delay leaf senescence and to extend the available time for photosynthesis. MicroRNAs (miRNAs) are key regulators of aging and cellular senescence in eukaryotes. Here, to help understand their biological role in rice leaf senescence, we report identification of miRNAs and their putative target genes by deep sequencing of six small RNA libraries, six RNA-seq libraries and two degradome libraries from the leaves of two super hybrid rice, Nei-2-You 6 (N2Y6, age-resistant rice) and Liang-You-Pei 9 (LYP9, age-sensitive rice). In total 372 known miRNAs, 162 miRNA candidates and 1145 targets were identified. Compared with the expression of miRNAs in the leaves of LYP9, the numbers of miRNAs up-regulated and down-regulated in the leaves of N2Y6 were 47 and 30 at early stage of grain-filling, 21 and 17 at the middle stage, and 11 and 37 at the late stage, respectively. Six miRNA families, osa-miR159, osa-miR160 osa-miR164, osa-miR167, osa-miR172 and osa-miR1848, targeting the genes encoding APETALA2 (AP2), zinc finger proteins, salicylic acid-induced protein 19 (SIP19), auxin response factors (ARF) and NAC transcription factors, respectively, were found to be involved in leaf senescence through phytohormone signaling pathways. These results provided valuable information for understanding the miRNA-mediated leaf senescence of rice, and offered an important foundation for rice breeding.",

Its dried root contains a number of tanshinones, protocatechuic aldehyde, salvianolic acid B and rosmarinic, and is used for the treatment of various diseases. The finding of microRNAs (miRNAs) and their target genes will help understand their biological role on the biosynthesis of tanshinones in S. miltiorrhiza. In the present study, a total of 452 known miRNAs corresponding to 589 precursor miRNAs (pre-miRNAs), and 40 novel miRNAs corresponding to 24 pre-miRNAs were identified in different tissues of S. miltiorrhiza by high-throughput sequencing, respectively. Among them, 62 miRNAs express only in root, 95 miRNAs express only in stem, 19 miRNAs express only in leaf, and 71 miRNAs express only in flower, respectively. By the degradome analysis, 69 targets potentially cleaved by 25 miRNAs were identified. Among them, acetyl-CoA C-acetyltransferase was cleaved by miR5072, and involved in the biosynthesis of tanshinones. This study provided valuable information for understanding the tissue-specific expression patterns of miRNAs in S. miltiorrhiza, and offered a foundation for future studies of the miRNA-mediated biosynthesis of tanshinones.",

The results indicated that zeatin had 62.8% to 89.1% of total cytokinins and was the dominant form of cytokinins in root exudates during early grain filling, whereas, the contents of diHZ and diHZR greatly increased during milk ripening. This change was consistent with the dynamic changes of ZRs (Z+ZR)and diHZRs (diHZ+diHZR)in flag leaves of IIyou 2070 and 2070. Different from main cytokinin composition in root exudates, IPAs took high proportion of total CTKs in leaf and grain. We suggested that there were changes of various forms and activities of root-derived cytokinins in root exudates, and this change was related to catabolic enzymes of cytokinins and the different expression of enzyme genes. Meanwhile, the relationship between cytokinin changes of vigorous and weak spikelets and grain filling was disscused.",

The leaf traits analyzed were leaf area, leaf length, leaf width, leaf perimeter and leaf length/width ratio measured on top first leaf, top second and top third leaves. The RIL population showed transgressive segregation on each trait, and highly significant or significant positive correlations were observed between all traits except between leaf length and width, and between leaf perimeter and length/width ratio. A total of 24 QTLs located in 9 intervals were detected to have significant additive effects for leaf traits analyzed, with LOD scores ranging 2.9-11.8 and 4.0%-32.5% phenotypic variation explained for a single QTL. Clustering of QTLs for leaf traits was evident. In interval RM197-RZ516 on chromosome 6, 2 QTLs for leaf length, 2 QTLs for leaf width and 3 QTLs for leaf length/width ratio of different leaves were detected, among which the alleles for increasing trait values were from Zhenshan 97B for leaf length and leaf length/width ratio, and from Milyang 46 for leaf width. In interval RM1-RG532 on chromosome 1,2 QTLs for leaf length and 2 QTLs for leaf perimeter were detected on top first leaf and top second leaf, respectively, and all the alleles for increasing trait values were from Milyang 46. In this interval, larger additive effects were observed for QTLs detected on top first leaf than at top second leaf. In interval RZ667-B10B on chromosome 6, a QTL for leaf perimeter of top second leaf was detected, accounting for 8.0% phenotypic variation. In intervals RZ66-RM264 and RG81-RM313 on chromosome 8 and 12, each QTL was detected for leaf length of top third leaf and explained for 9.0% and 15.3% phenotypic variation, respectively. Epistasis analysis detected 56 and 4 significant additive-by-additive interactions for leaf traits and root vitality, explaining 2.7% to 13.7% and 6.8% to 14.9% of the total phenotypic variation, respectively. On comparison with QTLs for yield traits detected in the same population previously, it was found that the majority of QTLs for leaf traits and root vitality and those for yield traits were located in similar intervals. Fine mapping of QTLs for both leaf and yield traits in these chromosomal regions would facilitate investigations of the source-sink relationship in rice.",

Their physical fitness was measured based on the China National Fitness Test Program including body shape, pulmonary function, and body fitness. A two-step cluster analysis determined the profiles that resulted from the interactions among motivation variables reflecting the degree of self-determination. Four distinct clusters of college women were identified: low self-determination/high control, low combination, high combination, and high self-determination/low control. There were significant differences among the clusters in physical activity involvement (p < .01, \u03b7 = .11), health-related quality of life (p < .01, \u03b7 = .18), and physical fitness (p < .01, \u03b7 = .04). Findings support the importance of developing self-determination in Chinese college women' physical activity, fitness and health-related quality of life.",

Sixty-one elementary physical educators from an urban school district in the midwestern U.S. were interviewed multiple times (N = 136) over 3 years using interpretive methodology. Teachers reported five unique challenges that significantly shaped their thinking about students and their careers, along with strategies they used to overcome or manage those challenges. The challenges were: (a) insufficient instructional resources, (b) implementing culturally relevant pedagogy, (c) dealing with community violence, (d) integrating more games in curricula, and (e) teaching in a culture of basketball. Implications centered on the guilt-inducing nature of urban teaching, developing an informed and realistic vision of urban physical education, and the role of teacher preparation and professional development.",

They were more likely to consume empty calorie food, meat, and fried food and less likely to eat fruit, vegetables, dairy products, and grains; they were less knowledgeable about dietary variables; and they had significantly lower self-efficacy regarding their ability to change dietary habits.The results of this study suggest that black students of low socioeconomic status should be targeted for early intervention related to dietary behaviors. This age group is amenable to change, and interventions designed specifically for them may result in lifetime reductions in risk of morbidity and mortality.",

The purpose of this study was to examine the effect of seductive details on students' learning of net games in physical education. Participants were 240 middle school students. A videotaped lesson example named \u201coutfox your opponent\u201d was used as the stimulus, and a 2 x 3 (condition x grade) factorial analysis was designed. The results showed that seductive details directly interrupted students' recall of important learning content and transferring problem solving in learning net games. It is suggested that the function of seductive details on learning should be reconsidered when designing effective motivational strategies in physical education.",

Ability beliefs and subjective task value were initially investigated as mediating the relationship between social support from friends and PA enjoyment. It was hypothesized that children play an active role in this socialization process with support seeking self-efficacy moderating the mediated relationships. Findings revealed PA social support from friends and PA enjoyment was mediated by PA ability beliefs, but this mediated relationship was conditional on children having average-to-high levels of support seeking self-efficacy. The mediated relationship between PA social support from friends and PA enjoyment through subjective task value was not moderated by support seeking self-efficacy. Results support the importance of instilling confidence in children to seek out PA support in order to maximize opportunities for PA enjoyment and suggest pathways may be more complex than originally posited in EVT.",

        "title": "The relationship between teacher burnout and student motivation",
        "abstract": "AbstractBackgroundTeacher burnout is regarded as a serious problem in school settings. To date, studies on teachers\u2019 stress and burnout have largely centred on teachers\u2019 own characteristics, socialization, and behaviours, but few have explored the connection between teachers\u2019 burnout and students\u2019 motivation via their own perceptions of teachers\u2019 behaviour and emotional well-being.AimsThis study adopted Maslach et\u00a0al.'s (2001, Annu. Rev. Psychol., 52, 397) job burnout construct and self-determination theory to investigate the relationships between teachers\u2019 burnout and students\u2019 autonomous motivation over one-semester physical education classes.SampleA total of 1,302 high school students and their 33 physical education teachers in 20 high schools from two school districts in a major Midwest metropolitan area in the United States. The two school districts were demographically similar.MethodsStudents and physical education teachers completed questionnaires assessing relevant psychological constructs. There were two time points for collecting students\u2019 data. One was at the beginning of a fall semester, and the other was at the end of that semester. Hierarchical linear modelling analyses were conducted.ResultsIt was revealed that teachers\u2019 emotional exhaustion was negatively related to students\u2019 perceived teacher autonomy support (TAS); in turn, there was a negative relationship between teachers\u2019 feeling of depersonalization and students\u2019 autonomous motivation development even when controlling for inadequate TAS.ConclusionThe dimensions of teachers' burnout might play different roles in the transmission from teachers to students. Teachers\u2019 status of burnout is an important environmental factor associated with students\u2019 quality of motivation.",

        "abstract": "Ferroelectric Ba(Sn 0.15 Ti 0.85 )O 3 (BTS) thin films were deposited on LaNiO 3 -coated silicon substrates via a sol\u2013gel process. Films showed a strong (1 0 0) preferred orientation depending upon annealing temperature and concentration of the precursor solution. The dependence of dielectric and ferroelectric properties on film orientation has been studied. The leakage current density of thin films at 100 kV/cm was 7 \u00d7 10 \u22127 A/cm 2 and 5 \u00d7 10 \u22125 A/cm 2 and their capacitor tunability was 54 and 25% at an applied field of 200 kV/cm (measurement frequency of 1 MHz) for the thin films deposited with 0.1 and 0.4 M spin-on solution, respectively. This work clearly reveals the highly promising potential of BTS compared with BST films for application in tunable microwave devices. Keywords A. Thin films B. Sol-gel chemistry D. Dielectric properties 1 Introduction Non-Pb based relaxor ferroelectrics materials are gaining importance because their processing parameters are easier to realize and integration in Si-device processing is comparatively easy to accomplish [1] . Depending on composition, some out of the many lead-free BaTiO 3 -based ceramics exhibit a relax behavior with characteristics related to the type of ionic substitutes and to substitution rate [1\u20134] . Lead-free composition in these materials could prove valuable for capacitors, actuators and dynamic random access memory applications, because they are environment-friendly. In ferroelectric composition, Ba 1\u2212 x Sr x TiO 3 exhibits four crystal structures: one paraelectric phase (cubic) and three ferroelectric ones (tetragonal, orthorhombic, and rhombohedral). These structural transitions are a hinderer to achieving stable ferroelectric crystalline structures in thin films. A solid solution of BaTiO 3 and BaSnO 3 expressed as Ba(Ti 1\u2212 x Sn x )O 3 (BTS). BaTiO 3 is a ferroelectric material with a Curie temperature of 120 \u00b0C, while BaSnO 3 is a paraelectric material with no ferroelectric phase transition. With increasing Sn concentration, the temperature of the ferroelectric\u2013paraelectric phase transformation decreases and becomes more diffuse within a wide temperature range. When the Sn ratio is between 10 and 20%, the ferroelectric transition of Ba(Ti 1\u2212 x Sn x )O 3 occurs between 0 and 60 \u00b0C. These compositions have no other structural phase transition in their ferroelectric state. Thus, a solid solution of BTS is expected to exhibit good ferroelectric characteristics and to be a good candidate for use not only in stable ferroelectric devices but in the study of general ferroelecric properties in the vicinity of Curie temperatures T c around room temperature [5\u20137] . Both, orthorhombic and rhombohedral single crystal of BaTiO 3 and Ba(Ti 1\u2212 x Zr x ) exhibited enhanced piezoelectric performance with polarization along the pseudocubic <0 0 1> direction [8,9] . Ba(Ti 1\u2212 x Sn x )O 3 ( x = 0.12) materials have an rhombohedral structure at room temperature [10] . It is expected that the enhanced dielectric performance can also be achieved at around room temperature in the <1 0 0> preferred orientation BTS thin films. Dielectric properties of BTS thin films as a function of Sn ratio have been reported for films deposited by pulse laser deposition (PLD) and the sol\u2013gel method [5,11,12] . However, the relationship of structural, substrate and dielectric properties has not been studied fully. In the present study, we report on the deposition of Ba(Sn 0.15 Ti 0.85 )O 3 (BTS) thin films on LaNiO 3 as buffer layer using Pt/Ti/SiO 2 /Si substrates and analyze the microstructure and dielectric behavior of the films. The influence of the concentration of the spin-on solution on crystalline microstructure and electrical properties of the films is investigated. 2 Experimental processing Barium acetate [Ba(CH 3 COO) 2 ], tin acetate [Sn(CH 3 COO) 4 ], and titaniun isopropoxide [Ti(OC 3 H 7 ) 4 ] were used as starting materials. Glacial acetic acid (CH 3 COOH), 2-methoxyethanol (CH 3 OCH 2 CH 2 OH), and ethylene glycol (CH 2 OHCH 2 OH) were used as solvent and polymerizing agents, respectively. Barium acetate and tin acetate were mixed according to a predetermined ratio and then added in the glacial acetic acid solution and heated to 120 \u00b0C to reflux 1 h. The ratio (Ba + Sn):glacial acetic acid was equal to 1:10 mol. After cooling to room temperature, the solution was mixed with the solution of Ti(OC 3 H 7 ) 4 and acetylacetone (AcAc CH 3 COCH 2 COCH 3 ) (Ti:AcAc=1:2 mol) under continues stirring. Finally, 2-methoxyethanol and ethylene glycol were added to control viscosity, cracking of films and the concentration of solution. The concentration of the final solution was adjusted to about 0.1 and 0.4 M, respectively. After aging the precursor solution for 24 h, the spin coating technique was employed to deposit the thin film on the LaNiO 3 /Pt/Ti/SiO 2 /Si(1 0 0) substrates by spin coating at 3000 rpm for 30 s each layer. The thicknesses of LaNiO 3 , Pt, Ti, and SiO 2 were 150 150, 50, and 150 nm, respectively. LNO was chosen as a template layer because it has a perovskite structure similar to BTS, good adhesion to the underlying platinum layer, and serves as a conductive oxide bottom electrode. The LNO layer was prepared by magnetron sputtering. Before spin coating with BTS, the LNO covered substrates were annealed at 800 \u00b0C for 30 min to promote grain growth. Each spin-coated BTS layer was subsequently heat-treated in air at 500 \u00b0C on a hot plate for 5 min. The coating and heat treatment procedures were repeated several times until reaching the desired thickness. Finally, the samples were heated at the rate of 10 \u00b0C/min to 750 \u00b0C for 30 min to crystalline the amorphous films. BTS films with a thickness of 520 nm (0.1 M spin-on solution) and 650 nm (0.4 M spin-on solution) were grown in this study. The crystalline phase of the thin films was identified by X-ray diffraction (BRUKER D8 Advance diffractometer). The film thickness and the surface morphology were determined by FESEM. For the electrical measurement, gold electrode pads of 400 \u03bcm \u00d7 400 \u03bcm were made on top of the BTS films by DC-sputtering. Hysteresis loops ( P \u2013 E ) of the thin films were obtained using the Radiant Technologies Precision Pro ferroelectric tester. The current\u2013voltage ( I \u2013 V ) characteristics were measured using a HP 4140B. The capacitance\u2013voltage ( C \u2013 V ) and capacitance\u2013temperature ( C \u2013 T ) characteristics were measured using an Agilent 4284A LCR meter. The sample\u2019s temperature was varied by means of a Delta chamber. Three samples were fabricated for each solution in these experiments. The X-ray diffraction patterns of three samples were the same. The results of P \u2013 E , I \u2013 V , C \u2013 V , and C \u2013 T were obtained using the same sample but different top Au electrodes (at least three elements) and only the mean value of three elements has been listed in this paper. 3 Results and discussion The use of a LNO buffer layer provides an excellent template facilitating the grain-on-grain growth so that highly oriented thin films with much improved properties are realized. Fig. 1 shows the XRD patterns for the BTS thin films. Evidence that the BTS films were perovskite phase only was clearly present at 750 \u00b0C with a preferred orientation of (1 0 0) for 0.1 M deposition thin films. For highly diluted spin-on solution, the single-coated layer is very thin (\u223c14 nm for 0.1 M). It is envisaged that for a sufficiently diluted spin-on solution, the single-coated layer is very thin and the condensation rate is low. Therefore, local grain-on-grain growth, or homoepitaxy, would occur at the interface between the new and the previous coating layer, thus resulting in highly preferred orientation [13] . On the other hand, when the spin-on solution concentration increases, each spin-on layer becomes thicker (\u223c65 nm for 0.4 M) because of the more abundant supply of molecules. Consequently, random nucleation would occur in the crystalline amorphous films as shown by Gust et al [14] . Fig. 2 shows SEM images of the sol\u2013gel deposited Ba(Sn 0.15 Ti 0.85 )O 3 thin films from: (a) 0.1 M; (b) 0.4 M spin-on solution; and (c) and (d) cross sectional morphology of (a) and (b), respectively. As shown in Fig. 2 , BTS thin films derived with 0.1 M solution have the grain size 50\u2013100 nm. The morphologies of the thin films deposited with 0.4 M solution shown in Fig. 2b show smaller grain size than that of thin films deposited with 0.1 M concentration solution, and presumably the highly oriented grains in the buffer layer could serve as seeds for the subsequently deposited crystalline BTS film. The larger-grained microstructure of the film apparently results in high dielectric constant. Hysteresis loops measured at room temperature for BTS thin films annealed at 750 \u00b0C are shown in Fig. 3 . It can be seen that BTS films deposited with 0.1 M spin-on solution have a larger saturated P\u2013E loops with larger remnant polarization and lower E c values that can be ascribed to their larger grains and highly (1 0 0) orientation. The switching in films with fine grains is relatively difficulty. The domain walls in larger grains were easies to switch under an external field, which domain in fine grains was more stable. Similar phenomenon found in SBT and PZT thin films were reported for the fine and larger grains [15,16] . The difference in the leakage current characteristics of 0.1 and 0.4 M spin-on solution deposited films is shown in Fig. 4 . The leakage currents density of thin films at 100 kV/cm was 7 \u00d7 10 \u22127 A/cm 2 and 5 \u00d7 10 \u22125 A/cm 2 for films deposited with 0.1 and 0.4 M spin-on solution, respectively. The leakage current density of 0.1 M spin-on solution deposited films is about two orders of magnitude lower than that of 0.4 M spin-on deposited films, which may be due to enhanced ionic polarization and improved crystallizability with larger grain size and (1 0 0) preferred orientation. The leakage current characteristics are distinctly different in the range of higher dc fields, both in the positive and negative voltage region. Fig. 4 shows that the reverse currents in the negative bias regions are much different from the forward currents in the positive bias region. This may be caused by generation of a different amount of oxygen vacancy at the top Au/BTS interface and at the bottom LNO/BTS interface [17] . The asymmetry between the positive and negative voltage parts of the J \u2013 V characteristic could be attributed to oxygen vacancies and movable ions at the top Au/BTS interface and the bottom LNO/BTS interface [17,18] in conjunction with identical top and bottom electrode work functions at the two interfaces. It also implies that the leakage current is electrode limited [19,20] . It is generally known that the leakage current of Pt/BST/Pt is controlled by Schottky barriers at the top and bottom BST/electrode interfaces. However, if these potential barriers were identical and equal numbers of oxygen vacancies existed at the interfaces of electrode and film, then the J \u2013 E characteristics would be symmetric. Fig. 5 shows the tunability of the capacitance as a function of applied dc voltage for BTS thin films at room temperature and in the frequency range of 100\u20131000 kHz. The bias E and dielectric constant \u03b5 were calculated from the bias voltage V and the capacitance C with the following equations: E = V / t , and \u03b5 = Ct / \u03b5 o A , where \u03b5 o is the permittivity of empty space, t the film thickness, and A the area of the Au electrode. The capacitance and dielectric loss tan\u03b4 was measured using an LCR meter at 100 kHz and 1 MHz, respectively; an ac field of 0.4 kV/cm superimposed on a slowly varying dc bias field. The dc bias was stepped through 0.2 V intervals and held 1 s prior to capacitance measurement. The functions of loss tangent measurements against bias voltage were similar in shape to the tuning curves. The dielectric constant tunability of the films can be expressed as ( \u03b5 (0) \u2212 \u03b5 ( E ))/ \u03b5 ( E ). The tunability of films deposited with 0.1 and 0.4 M spin-on solution was 54 and 25% at an applied field of 200 kV/cm and measurement frequency of 1 MHz, respectively. The values of dielectric loss at 1 MHz ranged from \u223c0.03 at zero bias to 0.02 at 200 kV/cm. In most cases, low loss and high dielectric tunability will be required. The temperature dependence of tunability will be discussed in another paper. The dielectric constant and dielectric loss of BTS thin films as a function of temperature is shown in Fig. 6 . The temperature dependence of the dielectric constant up to 180 \u00b0C was measured in a hot stage but is not shown here, since the results were in accordance with previous findings. Dielectric constant and dielectric loss were measured at a different frequency with an ac field of 0.4 kV/cm and 3 \u00b0C/min of heating rate. The \u03f5 \u2013 T characteristics were strongly frequency-dependent, especially at the point of phase transformation. Fig. 6 shows the dielectric loss data for the films, indicating the expected relationship between dielectric constant and dielectric loss. It is evident that the phase transition of thin films deposited with 0.1 and 0.4 M spin-on solution is between 5 and 35 \u00b0C and indicated the slightly diffused nature of the film, which is in agreement with the ceramic compositions [7] . Pure BaTiO 3 ceramic shows sharp PE\u2013FE phase transformation at 120 \u00b0C. The BaTiO 3 doped Sn changes character of the phase transformation from the sharp one to diffused nature. 4 Conclusion Ba(Sn 0.15 Ti 0.85 )O 3 thin films were prepared by sol\u2013gel processing. The films were single perovskite phase and highly (1 0 0) oriented. They were obtained on a LaNiO 3 buffer Pt/Ti/SiO 2 /Si substrates using a 0.1 M spin-on solution. A larger-grained microstructure of the films apparently results in a high dielectric constant. The leakage currents density of the thin films at 100 kV/cm was 7 \u00d7 10 \u22127 A/cm 2 and 5 \u00d7 10 \u22125 A/cm 2 and their capacitor tunability was 54 and 25% at an applied field of 200 kV/cm (measurement frequency of 1 MHz) for films deposited with 0.1 and 0.4 M spin-on solution, respectively. It is evident that the phase transition of thin films occurred between 5 and 35 \u00b0C. This is commensurate with the slightly diffused nature of the film.

Dense and uniform ceramic samples were obtained at sintering temperature of 940\u00b0C\u223c1060\u00b0C. The structure of these samples varies greatly with the change of compositions by means of XRD analyses. Based on the frequency and temperature dependence of dielectric constant and loss, dielectric properties were studied. It is shown that increasing the value of x decrease dielectric constant and does not result in dielectric loss degradation. Temperature coefficient of dielectric constant increases to positive and the stability of temperature coefficient become better especially in the case of x=0.15, for which the value of stability is just between \u00b15ppm/\u00b0C. Dielectric properties are closely related to phase structure in Bi2O3-(Zn1-xCax) O-Nb2O5 ceramics. \u00a9 2001 Taylor & Francis.",

The phase composition and microstructure of these powders were analyzed by X-ray diffraction and scanning electron microscopy. The mechanism of the tabular BaTiO3 growth was studied preliminarily. The results indicate that the two-steps molten salt process parameters and the mole ratio of raw materials greatly affect the microstructure of the intermediate Bi4Ti3O12. It was found that the tabular size increases with the increasing of the reaction temperature below 1 000 \u2103, and with the increasing of the amount of Bi2O3. In addition to the microstructure of the intermediate Bi4Ti3O12, the reaction temperature and the mole ratio of raw materials also have an obviously effect on the microstructure and size of the BaTiO3. The optimum synthesized conditions of tabular BaTiO3 powder are a mole ratio of BaTiO3 to Bi4Ti3O12 of 10:1, and synthesized at 1 000 \u2103 for 2 h.",

The films were of single perovskite phase with strong (1 0 0) preferred orientation when it were grown on LaNiO 3 buffered Pt/Ti/SiO 2 /Si substrates using a diluted precursor solution. Variation of the precursor solution concentration resulted in a different microstructure and, in turn, affected the dielectric properties of the sol\u2013gel deposited films. The BZT thin film showed a very stable and highly insulative characteristic against applied field.

XRD showed that the crystallinity of BZT film grown on LaNiO3 coated silicon substrates is better than that of BZT film grown on Pt. Both films showed perovskite phase and polycrystalline structure. The temperature dependent dielectric measurements revealed that the thin films had the relaxor behavior and diffuse phase transition characteristics. The capacitor tuning was about 44% for each BZT film grown on LaNiO3/Pt and Pt electrodes at 1 MHz. Especially, the values of dielectric loss at 1 MHz ranged from ~0.02 to 0.009 in the bias range of 0 to 514 kV/cm, respectively. The leakage currents density of thin films grown on LaNiO3/Pt and Pt electrodes at 300 kV/cm was about 8.5 \u00d7 10-7 and 1.1 \u00d7 10-5 A/cm2, respectively.

        "abstract": "Live poultry markets are a source of human infection with avian influenza A (H7N9) virus. On February 21, 2014, a poultry farmer infected with H7N9 virus was identified in Jilin, China, and H7N9 and H9N2 viruses were isolated from the patient's farm. Reassortment between these subtype viruses generated five genotypes, one of which caused the human infection. The date of H7N9 virus introduction to the farm is estimated to be between August 21, 2013 (95% confidence interval [CI] June 6, 2013-October 6, 2013) and September 25, 2013 (95% CI May 28, 2013-January 4, 2014), suggesting that the most likely source of virus introduction was the first batch of poultry purchased in August 2013. The reassortment event that led to the human virus may have occurred between January 2, 2014 (95% CI November 8, 2013-February 12, 2014) and February 12, 2014 (95% CI January 19, 2014-February 18, 2014). Our findings demonstrate that poultry farms could be a source of reassortment between H7N9 virus and H9N2 virus as well as human infection, which emphasizes the importance to public health of active avian influenza surveillance at poultry farms.",

Phylogenetic analysis suggested that Chinese Puumala virus had diverged from the common node of PUUV, with accumulating nucleotide substitutions and formed a distinct lineage from other Puumala viruses. Newly found Puumala virus was most closely related to the Kamiiso-8Cr-95 and Tobetsu-60Cr-93 strains which came from Japan and the muju strains which came from South Korea. By analysis of S and M genome segments of Puumala virus, we deduced a new Puumala virus subtype did exist in Northeast China.",

A set of general nonlinear equations described by sector-bounded nonlinearities is utilized to model the system and sensors in networks. Each sensor receives the information from both the system and its neighbors. The signal received by each sensor is sampled by a sampler separately with stochastic sampling periods before it is employed by the corresponding filter. By converting the sampling periods into bounded time-delays, the design problem of the stochastic sampled-data based distributed H\u221e filters amounts to solving the H\u221e filtering problem for a class of stochastic nonlinear systems with multiple bounded time-delays. Then, by constructing a new Lyapunov functional and employing both the Gronwall's inequality and the Jenson integral inequality, a sufficient condition is derived to guarantee the H\u221e performance as well as the exponential mean-square stability of the resulting filtering error dynamics. Subsequently, the desired sampled-data based distributed H\u221e filters are designed in terms of the solution to certain matrix inequalities that can be solved effectively by using available software. Finally, a numerical simulation example is exploited to demonstrate the effectiveness of the proposed sampled-data distributed H\u221e filtering scheme.",

The stochastic nonlinearities described by statistical means are quite general that include several well-studied classes of nonlinearities as special cases. A model of actuator failures is adopted which is more practical than the traditional outage one. A linear matrix inequality (LMI) approach is proposed to solve the multiobjective fault-tolerant controller design problem, where both the exponential stability and the steady-state state variance indices are simultaneously guaranteed. Within the developed LMI framework, a sufficient condition for the solvability of the robust control problem is obtained. The explicit expression of the desired controllers is also parameterized and a single degree-of-freedom (SDOF) model is used to demonstrate the effectiveness and applicability of the proposed design approach. \u00a92009 ACA.",

The missing-measurement phenomenon is assumed to occur in a random way, and the missing probability is time-varying with securable upper and lower bounds that can be measured in real time. The multiplicative noise is a state-dependent scalar Gaussian white-noise sequence with known variance. The addressed gain-scheduled filtering problem is concerned with the design of a filter such that, for the admissible random missing measurements, nonlinear parameters, and external noise disturbances, the error dynamics is exponentially mean-square stable. The desired filter is equipped with time-varying gains based primarily on the time-varying missing probability and is therefore less conservative than the traditional filter with fixed gains. It is shown that the filter parameters can be derived in terms of the measurable probability via the semidefinite program method. \u00a9 2011 IEEE.",

The system under study is not only corrupted by state-dependent white noises but also disturbed by exogenous inputs. The measurement output contains randomly missing data that is modeled by a Bernoulli distributed white sequence with a known conditional probability. A filter of very general form is first designed such that the filtering process is stochastically stable and the filtering error satisfies H\u221e performance constraint for all admissible missing observations and nonzero exogenous disturbances under the zero-initial condition. The existence conditions of the desired filter are described in terms of a second-order nonlinear inequality. Such an inequality can be decoupled into some auxiliary ones that can be solved independently by taking special form of the Lyapunov functionals. As a consequence, a linear time-invariant filter design problem is discussed for the benefit of practical applications, and some simplified conditions are obtained. Finally, two numerical simulation examples are given to illustrate the main results of this paper. \u00a9 2008 IEEE.",

        "abstract": "This article is concerned with a new distributed state estimation problem for a class of dynamical systems in sensor networks. The target plant is described by a set of differential equations disturbed by a Brownian motion and randomly occurring nonlinearities (RONs) subject to time delays. The RONs are investigated here to reflect network-induced randomly occurring regulation of the delayed states on the current ones. Through available measurement output transmitted from the sensors, a distributed state estimator is designed to estimate the states of the target system, where each sensor can communicate with the neighboring sensors according to the given topology by means of a directed graph. The state estimation is carried out in a distributed way and is therefore applicable to online application. By resorting to the Lyapunov functional combined with stochastic analysis techniques, several delay-dependent criteria are established that not only ensure the estimation error to be globally asymptotically stable in the mean square, but also guarantee the existence of the desired estimator gains that can then be explicitly expressed when certain matrix inequalities are solved. A numerical example is given to verify the designed distributed state estimators.",

        "abstract": "In this paper, the gain-scheduled control problem is addressed by using probability-dependent Lyapunov functions for a class of discrete-time stochastic delayed systems with randomly occurring sector nonlinearities. The sector nonlinearities are assumed to occur according to a time-varying Bernoulli distribution with measurable probability in real time. The multiplicative noises are given by means of a scalar Gaussian white noise sequence with known variances. The aim of the addressed gain-scheduled control problem is to design a controller with scheduled gains such that, for the admissible randomly occurring nonlinearities, time delays and external noise disturbances, the closed-loop system is exponentially mean-square stable. Note that the designed gain-scheduled controller is based on the measured time-varying probability and is therefore less conservative than the conventional controller with constant gains. It is shown that the time-varying controller gains can be derived in terms of the measurable probability by solving a convex optimization problem via the semi-definite programme method. A simulation example is exploited to illustrate the effectiveness of the proposed design procedures. \u00a9 2012 John Wiley & Sons, Ltd.",

The missing measurements are modeled via a diagonal matrix consisting of a series of mutually independent random variables satisfying certain probabilistic distributions on the interval [0,1]. The measured output is quantized by a logarithmic quantizer. Attention is focused on the design of a stochastic H\u221e filter such that the H\u221e estimation performance is guaranteed over a given finite-horizon in the simultaneous presence of probabilistic missing measurements, quantization effects as well as external non-Gaussian disturbances. A necessary and sufficient condition is first established for the existence of the desired time-varying filters in virtue of the solvability of certain coupled recursive Riccati difference equations (RDEs). Owing to its recursive nature, the proposed RDE approach is shown to be suitable for online application without the need of increasing the problem size. The simulation experiment is carried out for the mobile robot localization problem with non-Gaussian disturbances, missing measurements and quantization effects. The effectiveness of the proposed method is demonstrated in the numerical example. \u00a9 1963-2012 IEEE.",

        "abstract": "Abstract   In this paper, the centralized security-guaranteed filtering problem is studied for linear time-invariant stochastic systems with multirate-sensor fusion under deception attacks. The underlying system includes a number of sensor nodes with a centralized filter, where each sensor is allowed to be sampled at different rate. A new measurement output model is proposed to characterize both the multiple rates and the deception attacks. By exploiting the lifting technique, the multi-rate sensor system is cast into a single-rate discrete-time system. With a new concept of security level, the aim of this paper is to design a filter such that the filtering error dynamics achieves the prescribed level of the security under deception attacks. By using the stochastic analysis techniques, sufficient conditions are first derived such that the filtering error system is guaranteed to have the desired security level, and then the filter gain is parameterized by using the semi-definite programme method with certain nonlinear constraints. Finally, a numerical simulation example is provided to demonstrate the feasibility of the proposed filtering scheme.",

Based on the relative error with respect to the measurement signal, an event indicator variable is introduced and the corresponding event-triggered scheme is proposed in order to determine whether the measurement output is transmitted to the controller or not. The stochastic nonlinearities under consideration are characterized by statistical means which can cover several classes of well-studied nonlinearities. A set of unrelated random variables is exploited to govern the phenomena of randomly occurring saturations, stochastic nonlinearities and state-dependent noises. The purpose of the addressed multiobjective control problem is to design a set of time-varying output feedback controller such that, over a finite horizon, the closed-loop system achieves both the prescribed  H \u221e  noise attenuation level and the state covariance constraints. A recursive matrix inequality approach is developed to derive the sufficient conditions for the existence of the desired finite-horizon controllers, and the analytical characterization of such controllers is also given. Simulation studies are conducted to demonstrate the effectiveness of the developed controller design scheme.",

The DSMNN is subject to both the additive deterministic disturbances and the multiplicative stochastic noises. The missing measurements are governed by a sequence of random variables obeying the Bernoulli distribution. For the purpose of energy saving, an event-triggered communication scheme is used for DSMNNs to determine whether the measurement output is transmitted to the estimator or not. The problem addressed is to design an event-triggered    $H_infty $    estimator such that the dynamics of the estimation error is exponentially mean-square stable and the prespecified    $H_infty $    disturbance rejection attenuation level is also guaranteed. By utilizing a Lyapunov\u2013Krasovskii functional and stochastic analysis techniques, sufficient conditions are derived to guarantee the existence of the desired estimator, and then, the estimator gains are characterized in terms of the solution to certain matrix inequalities. Finally, a numerical example is used to demonstrate the usefulness of the proposed event-triggered state estimation scheme.",

The purpose of the addressed problem is to design a set of time-varying controllers such that, in the presence of channel fading and randomly occurring nonlinearities, the H performance is guaranteed over a given finite-horizon. The model transformation technique is first employed to simplify the addressed problem, and then the stochastic analysis in combination with the completing squares method are carried out to obtain necessary and sufficient conditions of an auxiliary index which is closely related to the finite-horizon H performance. Moreover, the time-varying controller parameters are characterized via solving coupled backward recursive Riccati difference equations (RDEs).

The extrinsic disturbance and intrinsic noises are described, respectively, by an unknown signal with finite energy and a set of scalar Brownian motions. The expression levels of the mRNA and protein of the considered genetic regulatory network are sampled and then transmitted to the filter in order to estimate the states of the genetic network under consideration. The corresponding filtering error dynamics is then represented by means of a system with time-varying delay. By constructing a simple yet practical Lyapunov functional that reflects all the information about the system complexity, sufficient conditions are established so as to guarantee both the exponential mean-square stability and the H\u221e performance for the filtering error dynamics. It is shown that the desired sampled-data H \u221e filter exists if certain matrix inequalities are solvable where the solvability can be readily checked by using the available software.

        "abstract": "In this paper, a new H filtering approach is developed for a class of discrete time-varying systems subject to missing measurements and quantization effects. The missing measurements are modeled via a diagonal matrix consisting of a series of mutually independent random variables satisfying certain probabilistic distributions on the interval [0,1] . The measured output is quantized by a logarithmic quantizer. Attention is focused on the design of a stochastic H filter such that the H estimation performance is guaranteed over a given finite-horizon in the simultaneous presence of probabilistic missing measurements, quantization effects as well as external non-Gaussian disturbances. A necessary and sufficient condition is first established for the existence of the desired time-varying filters in virtue of the solvability of certain coupled recursive Riccati difference equations (RDEs). Owing to its recursive nature, the proposed RDE approach is shown to be suitable for online application without the need of increasing the problem size. The simulation experiment is carried out for the mobile robot localization problem with non-Gaussian disturbances, missing measurements and quantization effects. The effectiveness of the proposed method is demonstrated in the numerical example.",

The system under consideration involves fading measurements, randomly occurring nonlinearities (RONs) and mixed (multiplicative and additive) noises. A novel envelope-constrained performance criterion is proposed to better quantify the transient dynamics of the filtering error process over the finite horizon. The purpose of the problem addressed is to design a time-varying filter such that both the H \u221e performance and the desired envelope constraints are achieved at each time step. By utilizing the stochastic analysis techniques combined with the ellipsoid description on the estimation errors, sufficient conditions are established in the form of recursive matrix inequalities (RMIs) reflecting both the envelope information and the desired H \u221e performance index. The filter gain matrix is characterized by means of the solvability of the deduced RMIs. Finally, a simulation example is provided to show the effectiveness of the proposed filtering design scheme.",

In this paper, a fundamental stabilization problem is investigated for a class of sampled-data systems under noisy sampling interval. The stochastic sampled-data control system under consideration is first converted into a discrete-time system whose system matrix is represented as an equivalent yet tractable form via the matrix exponential computation. Then, by introducing a Vandermonde matrix, the mathematical expectation of the quadratic form of the system matrix is computed. By recurring to the Kronecker product operation, the sampled-data stabilization controller is designed such that the closed-loop system is stochastically stable in the presence of noisy sampling interval. Subsequently, a special case is considered where the sampling interval obeys the continuous uniform distribution and the corresponding stabilization controller is designed. Finally, a numerical simulation example is provided to demonstrate the effectiveness of the proposed design approach.",

By introducing a stochastic Kronecker delta function, these incomplete measurements are described in a unified way and a novel measurement model is proposed to account for these phenomena occurring with individual probability. With the measurement model, a set of H\u221e state estimators is designed such that, for all admissible incomplete measurements as well as the uncertain coupling strength, the estimation error dynamics is exponentially mean-square stable and the H\u221e performance requirement is satisfied. The characterization of the desired estimator gains is derived in terms of the solution to a convex optimization problem that can be easily solved using the semidefinite program method.

A sequence of mutually independent random variables obeying the Bernoulli distribution is introduced to account for the randomly occurred communication delays. Both the discrete-time target plant and the sensor model are subject to parameter uncertainties as well as stochastic disturbance. The parameter uncertainties are norm-bounded and enter both the system and the measurement matrices. The external stochastic disturbance is given in the form of a scalar Wiener process. Through available output measurements from not only each individual sensor but also its neighbouring sensors, we aim to design distributed state estimators in order to approximate the state of the target plant. By using the Kronecker product, stochastic analysis is carried out to derive a sufficient criterion ensuring the estimation error systems to be convergent in the mean square sense for all randomly occurred delays, admissible stochastic disturbance and parameter uncertainties. Then, an explicit expression of the individual estimator is given in terms of the solution to a convex optimisation problem that can be easily solved by using the semi-definite programme method.

        "abstract": "In this paper, new synchronization and state estimation problems are considered for an array of coupled discrete time-varying stochastic complex networks over a finite horizon. A novel concept of bounded H\u221e synchronization is proposed to handle the time-varying nature of the complex networks. Such a concept captures the transient behavior of the time-varying complex network over a finite horizon, where the degree of bounded synchronization is quantified in terms of the H\u221e-norm. A general sector-like nonlinear function is employed to describe the nonlinearities existing in the network. By utilizing a timevarying real-valued function and the Kronecker product, criteria are established that ensure the bounded H\u221e synchronization in terms of a set of recursive linear matrix inequalities (RLMIs), where the RLMIs can be computed recursively by employing available MATLAB toolboxes. The bounded H\u221e state estimation problem is then studied for the same complex network, where the purpose is to design a state estimator to estimate the network states through available output measurements such that, over a finite horizon, the dynamics of the estimation error is guaranteed to be bounded with a given disturbance attenuation level. Again, an RLMI approach is developed for the state estimation problem. Finally, two simulation examples are exploited to show the effectiveness of the results derived in this paper.",

We consider a situation where the filter is located in a remote area from the sensor and the transmission of the measurements from the sensor to the filter may consume certain energy stored in sensor. The underlying sensor is capable of harvesting the energy from the environment. The transmission of the measurements is closely related to the sensor\u2019s energy level and, for the remote filter, the measurements are regarded as missing when the sensor energy is insufficient to maintain the normal communication between the sensor and the filter. In order to derive the missing rate of the measurements, the probability distribution of the amount of the sensor energy is calculated recursively at each time instant. Then, in the presence of parameter nonlinearities, time delays as well as the probabilistic missing measurements resulting from the limited capacity of the sensor, we design a finite-horizon filter such that an upper bound is guaranteed on the filtering error covariance at each time instant and the filter gain minimizing such an upper bound is subsequently obtained in terms of the solution to a set of recursive equations. Finally, a numerical simulation example is employed to demonstrate the effectiveness of the proposed filtering scheme.",

A new H\\infty performance index including the known inputs is put forward in order to better reflect the effect of the known input on the whole fault estimation systems. To cope with the uncertainties, an auxiliary system is constructed with a certain indefinite quadratic form. By recurring to the Krein-space theory, the optimization problem of the associated indefinite quadratic form is solved, and a sufficient condition with much less conservativeness is established for the existence of the desired fault estimator. Then, all the estimator parameters are derived simultaneously in terms of an explicit solution to a matrix equation.

A new robust H\"~ filtering technique is developed for the addressed Ito-type discrete time-varying stochastic systems. Such a technique relies on the forward solution to a set of recursive linear matrix inequalities and is therefore suitable for on-line computation.

A novel definition of  consensus in probability  is proposed to better describe the dynamics of the consensus process of the addressed stochastic multi-agent systems. The measurement output available for the controller is not only from the individual agent but also from its neighboring ones according to the given topology. An event-triggered mechanism is adopted with hope to reduce the communication burden, where the control input on each agent is updated only when a certain triggering condition is violated. The purpose of the problem under consideration is to design  both  the output feedback controller  and  the threshold of the triggering condition such that the closed-loop system achieves the desired consensus in probability. First of all, a theoretical framework is established for analyzing the so-called  input-to-state stability in probability  (ISSiP) for general discrete-time nonlinear stochastic systems. Within such a theoretical framework, some sufficient conditions on event-triggered control protocol are derived under which the consensus in probability is reached. Furthermore, both the controller parameter and the triggering threshold are obtained in terms of the solution to certain matrix inequalities involving the topology information and the desired consensus probability. Finally, a simulation example is utilized to illustrate the usefulness of the proposed control protocol.",

A nonlinear stochastic system with state delays is employed to model the networked control systems where the measured output and the input signals are quantized by two logarithmic quantizers, respectively. Moreover, the data missing phenomena are modeled by introducing a diagonal matrix composed of Bernoulli distributed stochastic variables taking values of 1 and 0, which describes that the data from different sensors may be lost with different missing probabilities. Subsequently, a sufficient condition is first derived in virtue of the method of sector-bounded uncertainties, which guarantees that the closed-loop system is stochastically stable and the controlled output satisfies H\u221e performance constraint for all nonzero exogenous disturbances under the zero-initial condition. Then, the sufficient condition is decoupled into some inequalities for the convenience of practical verification. Based on that, quantized H\u221e controllers are designed successfully for some special classes of nonlinear stochastic time-delay systems by using Matlab linear matrix inequality toolbox.

The mixed delays, which comprise both discrete and distributed delays, are allowed to occur in a random manner governed by two mutually independent Bernoulli distributed random variables. In order to alleviate the communication burden, an event-triggered mechanism is utilized for each sensor node to decide whether or not its current information should be broadcasted to its neighbors. The aim of this paper is to design event-triggered state estimators such that the error dynamics of state estimation is exponentially mean-square stable with a prescribed  H  \u221e  performance index. By resorting to intensive stochastic analysis, sufficient conditions are first derived to guarantee the existence of the desired estimators, and the parameters of the desired distributed estimators are then obtained in light of the feasibility of a certain set of matrix inequalities. A numerical example is employed to illustrate the usefulness of the proposed distributed estimation algorithm.",

        "abstract": "In this paper, new synchronization and state estimation problems are considered for an array of coupled discrete time-varying stochastic complex networks over a finite horizon. A novel concept of bounded H(\u221e) synchronization is proposed to handle the time-varying nature of the complex networks. Such a concept captures the transient behavior of the time-varying complex network over a finite horizon, where the degree of bounded synchronization is quantified in terms of the H(\u221e)-norm. A general sector-like nonlinear function is employed to describe the nonlinearities existing in the network. By utilizing a time-varying real-valued function and the Kronecker product, criteria are established that ensure the bounded H(\u221e) synchronization in terms of a set of recursive linear matrix inequalities (RLMIs), where the RLMIs can be computed recursively by employing available MATLAB toolboxes. The bounded H(\u221e) state estimation problem is then studied for the same complex network, where the purpose is to design a state estimator to estimate the network states through available output measurements such that, over a finite horizon, the dynamics of the estimation error is guaranteed to be bounded with a given disturbance attenuation level. Again, an RLMI approach is developed for the state estimation problem. Finally, two simulation examples are exploited to show the effectiveness of the results derived in this paper.",

The system under study is not only corrupted by state-dependent white noises but also disturbed by exogenous inputs. The measurement output contains randomly missing data that is modeled by a Bernoulli distributed white sequence with a known conditional probability. A filter of very general form is first designed such that the filtering process is stochastically stable and the filtering error satisfies H infin performance constraint for all admissible missing observations and nonzero exogenous disturbances under the zero-initial condition. The existence conditions of the desired filter are described in terms of a second-order nonlinear inequality. Such an inequality can be decoupled into some auxiliary ones that can be solved independently by taking special form of the Lyapunov functionals. As a consequence, a linear time-invariant filter design problem is discussed for the benefit of practical applications, and some simplified conditions are obtained. Finally, two numerical simulation examples are given to illustrate the main results of this paper.",

Two mutually independent sequences of random variables that obey the Bernoulli distribution are employed to describe the random occurrence of the nonlinearities and packet dropouts. The purpose of the addressed problem is to design a time-varying filter such that the H\u221e disturbance attenuation level is guaranteed, over a given finite-horizon, for the filtering error dynamics in the presence of saturated states, randomly occurring nonlinearities, and successive packet dropouts. By introducing a free matrix with its infinity norm less than or equal to 1, the error state is bounded by a convex hull so that some sufficient conditions obtained via solving a certain set of recursive nonlinear matrix inequalities. Furthermore, the obtained results are extended to the case when state saturations are partial.

        "abstract": "In this paper, the quantized H \u221e control problem is investigated for a class of nonlinear stochastic time-delay network-based systems with probabilistic data missing. A nonlinear stochastic system with state delays is employed to model the networked control systems where the measured output and the input signals are quantized by two logarithmic quantizers, respectively. Moreover, the data missing phenomena are modeled by introducing a diagonal matrix composed of Bernoulli distributed stochastic variables taking values of 1 and 0, which describes that the data from different sensors may be lost with different missing probabilities. Subsequently, a sufficient condition is first derived in virtue of the method of sector-bounded uncertainties, which guarantees that the closed-loop system is stochastically stable and the controlled output satisfies H \u221e performance constraint for all nonzero exogenous disturbances under the zero-initial condition. Then, the sufficient condition is decoupled into some inequalities for the convenience of practical verification. Based on that, quantized H \u221e controllers are designed successfully for some special classes of nonlinear stochastic time-delay systems by using Matlab linear matrix inequality toolbox. Finally, a numerical simulation example is exploited to show the effectiveness and applicability of the results derived. \u00a9 2011 IEEE.",

The sampling period considered here is assumed to be time-varying that switches between two different values in a random way with given probability. The addressed synchronization control problem is first formulated as an exponentially mean-square stabilization problem for a new class of dynamical networks that involve both the multiple probabilistic interval delays (MPIDs) and the sector-bounded nonlinearities (SBNs). Then, a novel Lyapunov functional is constructed to obtain sufficient conditions under which the dynamical network is exponentially mean-square stable. Both Gronwall's inequality and Jenson integral inequality are utilized to substantially simplify the derivation of the main results. Subsequently, a set of sampled-data synchronization controllers is designed in terms of the solution to certain matrix inequalities that can be solved effectively by using available software. Finally, a numerical simulation example is employed to show the effectiveness of the proposed sampled-data synchronization control scheme. \u00a9 2012 IEEE.",

The missing measurements are modelled by a series of mutually independent random variables obeying Bernoulli distributions with possibly different occurrence probabilities. The quantisation phenomenon is described by using the logarithmic function and the multiplicative noises are considered to account for the stochastic disturbances on the system states. Attention is focused on the design of a recursive filter such that, for all multiplicative noises, missing measurements as well as quantisation effects, an upper bound for the filtering error covariance is guaranteed and such an upper bound is subsequently minimised by properly designing the filter parameters at each sampling instant. The desired filter parameters are obtained by solving two Riccati-like difference equations that are of a recursive form suitable for online applications.

The so-called H \u221e -consensus performance requirement is defined to quantify bounded consensus regarding the filtering errors (agreements) over a finite-horizon. A set of random variables are utilized to model the probabilistic information missing phenomena occurring in the channels from the system to the sensors. A sufficient condition is first established in terms of a set of difference linear matrix inequalities (DLMIs) under which the expected H \u221e -consensus performance constraint is guaranteed. Given the measurements and estimates of the system state and its neighbors, the filter parameters are then explicitly parameterized by means of the solutions to a certain set of DLMIs that can be computed recursively. Subsequently, two kinds of robust distributed H \u221e -consensus filters are designed for the system with norm-bounded uncertainties and polytopic uncertainties. Finally, two numerical simulation examples are used to demonstrate the effectiveness of the proposed distributed filters design scheme.",

        "abstract": "In this paper, the quantized H control problem is investigated for a class of nonlinear stochastic time-delay network-based systems with probabilistic data missing. A nonlinear stochastic system with state delays is employed to model the networked control systems where the measured output and the input signals are quantized by two logarithmic quantizers, respectively. Moreover, the data missing phenomena are modeled by introducing a diagonal matrix composed of Bernoulli distributed stochastic variables taking values of 1 and 0, which describes that the data from different sensors may be lost with different missing probabilities. Subsequently, a sufficient condition is first derived in virtue of the method of sector-bounded uncertainties, which guarantees that the closed-loop system is stochastically stable and the controlled output satisfies H performance constraint for all nonzero exogenous disturbances under the zero-initial condition. Then, the sufficient condition is decoupled into some inequalities for the convenience of practical verification. Based on that, quantized H controllers are designed successfully for some special classes of nonlinear stochastic time-delay systems by using Matlab linear matrix inequality toolbox. Finally, a numerical simulation example is exploited to show the effectiveness and applicability of the results derived.",

A set of measurement models is established for each sensor node that describes all the available information from the node and its neighbors.

        "abstract": "Nonlinear Stochastic Processes addresses the frequently-encountered problem of incomplete information. The causes of this problem considered here include: missing measurements; sensor delays and saturation; quantization effects; and signal sampling. Divided into three parts, the text begins with a focus on H filtering and control problems associated with general classes of nonlinear stochastic discrete-time systems. Filtering problems are considered in the second part, and in the third the theory and techniques previously developed are applied to the solution of issues arising in complex networks with the design of sampled-data-based controllers and filters. Among its highlights, the text provides: a unified framework for filtering and control problems in complex communication networks with limited bandwidth; new concepts such as random sensor and signal saturations for more realistic modeling; and demonstration of the use of techniques such as the HamiltonJacobiIsaacs, difference linear matrix, and parameter-dependent matrix inequalities and sums of squares to handle the computational challenges inherent in these systems. The collection of recent research results presented in Nonlinear Stochastic Processes will be of interest to academic researchers in control and signal processing. Graduate students working with communication networks with lossy information and control of stochastic systems will also benefit from reading the book.",

        "abstract": "This paper is concerned with the robust H\u221e finite-horizon filtering problem for discrete time-varying stochastic systems with multiple randomly occurred sector-nonlinearities (MROSNs) and successive packet dropouts. MROSNs are proposed to model a class of sector-like nonlinearities that occur according to the multiple Bernoulli distributed white sequences with a known conditional probability. Different from traditional approaches, in this paper, a time-varying filter is designed directly for the addressed system without resorting to the augmentation of system states and measurement, which helps reduce the filter order. A new H\u221e filtering technique is developed by means of a set of recursive linear matrix inequalities that depend on not only the current available state estimate but also the previous measurement, therefore ensuring a better accuracy. Finally, two illustrative examples are used to demonstrate the effectiveness and applicability of the proposed filter design scheme. Copyright \u00a9 2010 John Wiley & Sons, Ltd.",

        "abstract": "In this paper, the H\"~ filtering problem is investigated for a class of nonlinear systems with randomly occurring incomplete information. The considered incomplete information includes both the sensor saturations and the missing measurements. A new phenomenon of sensor saturation, namely, randomly occurring sensor saturation (ROSS), is put forward in order to better reflect the reality in a networked environment such as sensor networks. A novel sensor model is then established to account for both the ROSS and missing measurement in a unified representation by using two sets of Bernoulli distributed white sequences with known conditional probabilities. Based on this sensor model, a regional H\"~ filter with a certain ellipsoid constraint is designed such that the filtering error dynamics is locally mean-square asymptotically stable and the H\"~-norm requirement is satisfied. Note that the regional l\"2 gain filtering feature is specifically developed for the random saturation nonlinearity. The characterization of the desired filter gains is derived in terms of the solution to a convex optimization problem that can be easily solved by using the semi-definite program method. Finally, a simulation example is employed to show the effectiveness of the filtering scheme proposed in this paper.",

        "abstract": "Abstract   In this paper, the robust recursive filtering problem is investigated for a class of uncertain stochastic discrete time-varying spatial-temporal systems with an event-based communication mechanism. The system under consideration includes a set of sensors located at specified points where each sensor can only receive the measurement output from the system at corresponding position. In order to reduce the communication cost, an event-triggered mechanism is utilized to decide when a certain measurement output should be transmitted from sensors to the centralized filter. By re-organizing the state variables, the uncertain spatial-temporal system is first transformed into an ordinary uncertain difference dynamic system. The aim of this paper is to design a filter such that, for all possible parameter uncertainties, the filtering error covariance is guaranteed to have an upper bound which is then minimized at each time-instant under the event-triggered mechanism. By using the matrix derivation approach, the desired filter gain is obtained in terms of the solution to certain Riccati-like difference equations. Finally, a numerical example is employed to demonstrate the effectiveness of the filtering scheme proposed.",

        "abstract": "In this paper, the H infin filtering problem is investigated for a general class of nonlinear discrete-time stochastic systems with missing measurements. The system under study is not only corrupted by state-dependent white noises but also disturbed by exogenous inputs. The measurement output contains randomly missing data that is modeled by a Bernoulli distributed white sequence with a known conditional probability. A filter of very general form is first designed such that the filtering process is stochastically stable and the filtering error satisfies H infin performance constraint for all admissible missing observations and nonzero exogenous disturbances under the zero-initial condition. The existence conditions of the desired filter are described in terms of a second-order nonlinear inequality. Such an inequality can be decoupled into some auxiliary ones that can be solved independently by taking special form of the Lyapunov functionals. As a consequence, a linear time-invariant filter design problem is discussed for the benefit of practical applications, and some simplified conditions are obtained. Finally, two numerical simulation examples are given to illustrate the main results of this paper.",

        "abstract": "In this paper, the event-triggered H \u221e state estimation problem is investigated for a class of neural networks with mixed time delays and sensor saturations. The mixed time delays consist of discrete and distributed delays. The measurement outputs are subject to the sensor saturations due to the physical constraints. Through the available measurement outputs, the main purpose of the addressed problem is to design a state estimator to estimate the actual neural states. In order to improve the efficiency in resource utilization, an event-triggered mechanism is employed to decide whether the received measurement output is transmitted to the state estimator. Different from the existing event-triggering strategies, the triggering condition is given for each sensor, and the measurement output from each sensor is sent according to their separate triggering conditions. By using the Lyapunov functional approach, sufficient conditions are derived to guarantee that the estimation error dynamics is exponentially stable and the H \u221e performance requirement is satisfied. Then, the desired H \u221e state estimator is designed in terms of the solution to a linear matrix inequality that can be easily solved by the MATLAB toolboxes. Finally, one simulation example is provided to show the effectiveness of the proposed event-triggered estimation scheme.",

The nonlinearity is represented by a linear form with a norm-bounded uncertainty. In order to deal with the uncertainty resulting from the nonlinearities, a new augmentation approach is proposed to transform the multi-rate nonlinear system into a single-rate system. Based on the measurement outputs according to the event-triggering mechanism, an extended Kalman filter is adopted to estimate the systems state.

The incomplete information under consideration includes randomly occurring sensor saturations and quantizations.

A novel definition of consensus in probability is proposed to better describe the dynamics of the consensus process of the addressed stochastic multi-agent systems. The measurement output available for the controller is not only from the individual agent but also from its neighboring ones according to the given topology. An event-triggered mechanism is adopted with hope to reduce the communication burden, where the control input on each agent is updated only when a certain triggering condition is violated. The purpose of the problem under consideration is to design both the output feedback controller and the threshold of the triggering condition such that the closed-loop system achieves the desired consensus in probability. First of all, a theoretical framework is established for analyzing the so-called input-to-state stability in probability (ISSiP) for general discrete-time nonlinear stochastic systems. Within such a theoretical framework, some sufficient conditions on event-triggered control protocol are derived under which the consensus in probability is reached. Furthermore, both the controller parameter and the triggering threshold are obtained in terms of the solution to certain matrix inequalities involving the topology information and the desired consensus probability.

        "abstract": "In this paper, the event-triggered state estimation problem is investigated for a class of discrete-time stochastic memristive neural networks (DSMNNs) with time-varying delays and missing measurements. The DSMNN is subject to both the additive deterministic disturbances and the multiplicative stochastic noises. The missing measurements are governed by a sequence of random variables obeying the Bernoulli distribution. For the purpose of energy saving, an event-triggered communication scheme is used for DSMNNs to determine whether the measurement output is transmitted to the estimator or not. The problem addressed is to design an event-triggered estimator such that the dynamics of the estimation error is exponentially mean-square stable and the prespecified disturbance rejection attenuation level is also guaranteed. By utilizing a Lyapunov-Krasovskii functional and stochastic analysis techniques, sufficient conditions are derived to guarantee the existence of the desired estimator, and then, the estimator gains are characterized in terms of the solution to certain matrix inequalities. Finally, a numerical example is used to demonstrate the usefulness of the proposed event-triggered state estimation scheme.",

        "title": "Exponential Synchronization for Delayed Dynamical Networks via Intermittent Control: Dealing With Actuator Saturations.",
        "abstract": "Over the past two decades, the synchronization problem for dynamical networks has drawn significant attention due to its clear practical insight in biological systems, social networks, and neuroscience. In the case where a dynamical network cannot achieve the synchronization by itself, the feedback controller should be added to drive the network toward a desired orbit. On the other hand, the time delays may often occur in the nodes or the couplings of a dynamical network, and the existence of time delays may induce some undesirable dynamics or even instability. Moreover, in the course of implementing a feedback controller, the inevitable actuator limitations could downgrade the system performance and, in the worst case, destabilize the closed-loop dynamics. The main purpose of this paper is to consider the synchronization problem for a class of delayed dynamical networks with actuator saturations. Each node of the dynamical network is described by a nonlinear system with a time-varying delay and the intermittent control strategy is proposed. By using a combination of novel sector conditions, piecewise Lyapunov-like functionals and the switched system approach, delay-dependent sufficient conditions are first obtained under which the dynamical network is locally exponentially synchronized. Then, the explicit characterization of the controller gains is established by means of the feasibility of certain matrix inequalities. Furthermore, optimization problems are formulated in order to acquire a larger estimate of the set of initial conditions for the evolution of the error dynamics when designing the intermittent controller. Finally, two examples are given to show the benefits and effectiveness of the developed theoretical results.",

The main purpose of the addressed issue is to propose a state estimator design algorithm that ensures the error dynamics of the state estimation to be stochastically stable with a prespecified H\u221e disturbance attenuation index. We put forward certain switching functions to account for the discrete-time yet state-dependent characteristics of the memristive connection weights. By resorting to the robust analysis theory and the Lyapunov-functional analysis theory, we derive some sufficient conditions to guarantee the desired estimation performance. The derived sufficient conditions rely not only on the size of discrete time-delays and the probability distribution law of the distributed time-delays but also on the statistics information of the coefficients of the adopted Rice fading model. Based on the established existence conditions, the gain matrices of the desired estimator are obtained by means of the feasibility of a set of matrix inequalities that can be checked efficiently via available software packages. Finally, the numerical simulation results are provided to show the validity of the main results.",

        "abstract": "SummaryIn this paper, the security-guaranteed filtering problem is studied for a class of nonlinear stochastic discrete time-delay systems with randomly occurring sensor saturations (ROSSs) and randomly occurring deception attacks (RODAs). The nonlinearities in systems satisfy the sector-bounded conditions, and the time-varying delays are unknown with given lower and upper bounds. A novel measurement output model is proposed to reflect both the ROSSs and the RODAs. A new definition is put forward on the security level with respect to the noise intensity, the energy bound of the false signals, the energy of the initial system state, and the desired security degree. We aim at designing a filter such that, in the presence of ROSSs and RODAs, the filtering error dynamics achieves the prescribed level of security. By using the stochastic analysis techniques, a sufficient condition is first derived under which the filtering error system is guaranteed to have the desired security level, and then, the filter gain is designed by solving a linear matrix inequality with nonlinear constraints.

For the efficiency of energy utilization, we make the first attempt to introduce a dynamic event-triggering strategy into the design of synchronization controllers for complex dynamical networks. A new discrete-time version of the dynamic event-triggering mechanism is proposed in terms of the absolute errors between control input updates. By constructing an appropriate Lyapunov functional, the dynamics of each network node combined with the introduced event-triggering mechanism are first analyzed, and a sufficient condition is then provided under which the synchronization error dynamics is exponentially ultimately bounded. Subsequently, a set of the desired synchronization controllers is designed by solving a matrix inequality. Finally, a simulation example is provided to verify the effectiveness of the proposed dynamic event-triggered synchronization control scheme.",

A random variable obeying the Erlang distribution is used to describe the noisy sampling intervals. In virtue of the matrix exponential, the sampled-data control system is transformed into an equivalent discrete-time stochastic system, and the aim of this paper is to design a quantized/saturated sampled-data controller such that the resulting discrete-time stochastic system is stochastically stable when the sampling error follows the Erlang distribution. In order to deal with the case of multiple control inputs, a confluent Vandermonde matrix approach is proposed in the design process. By using the Kronecker product operation and the matrix inequality techniques, the desired quantized/saturated controller gains are designed in terms of the solution to certain matrix inequalities.

Based on the relative error with respect to the measurement signal, an event indicator variable is introduced and the corresponding event-triggered scheme is proposed in order to determine whether the measurement output is transmitted to the controller or not. The stochastic nonlinearities under consideration are characterized by statistical means which can cover several classes of well-studied nonlinearities. A set of unrelated random variables is exploited to govern the phenomena of randomly occurring saturations, stochastic nonlinearities and state-dependent noises. The purpose of the addressed multiobjective control problem is to design a set of time-varying output feedback controller such that, over a finite horizon, the closed-loop system achieves both the prescribed H \u221e noise attenuation level and the state covariance constraints. A recursive matrix inequality approach is developed to derive the sufficient conditions for the existence of the desired finite-horizon controllers, and the analytical characterization of such controllers is also given. Simulation studies are conducted to demonstrate the effectiveness of the developed controller design scheme.",

        "abstract": "Abstract   This paper is concerned with a new fault detection scheme for linear discrete timevarying systems by using an H\u221e disturbance estimation approach. A unified estimation problem is formulated for linear discrete time-varying systems in an H\u221e framework. Such a formulation not only achieves a novel H\u221e disturbance estimation problem but also includes the classical H\u221e fault estimation as a special case. By using projection and innovation analysis in the Krein space, the H\u221e disturbance and fault estimation problems are solved in a unified way, and their estimates are given in terms of the solution to a set of Riccati difference equations. Then, both the H\u221e disturbance and fault estimates are used as residuals for the purpose of fault detection, and the detection performances are discussed based on these two residual generation strategies. It is an interesting finding that, in the case of sensor fault-free, the H\u221e fault estimation approach is no longer available while the H\u221e disturbance estimation approach is still effective. Finally, a simulation example is employed to illustrate the results derived in this paper.",

        "abstract": "In this paper, the simultaneous unknown input and state estimation problem is investigated for a class of linear discrete time-varying systems in sensor networks with missing measurements. Sensor nodes under consideration are distributed in space according to a fixed network topology, and each sensor receives the information from both the system and its neighbors. The missing measurement phenomenon on each sensor occurs in a random way and is governed by a series of mutually independent random variables obeying a certain Bernoulli distribution. To deal with the sparsity issue of estimator gain matrix, a set of measurement models is established for each sensor to describe all available information from the node itself and its neighbors. Our attention is focused on the design of a recursive estimator for every sensor node to simultaneously estimate unknown input and state in the sense of unbiased minimum-variance. Using direct algebraic operation, we obtain the estimator parameter matrices recursively, and the design algorithm is also provided. Finally, an illustrative example is presented to demonstrate the effectiveness of the proposed design scheme.",

        "abstract": "PurposeThe purpose of this paper is to improve the performance of the genetic algorithm-based compliant robot path planning (GACRPP) in complex dynamic environment by proposing an improved bidirectional rapidly exploring random tree (Bi-RRT)-based population initialization method.Design/methodology/approachTo achieve GACRPP in complex dynamic environment with high performance, an improved Bi-RRT-based population initialization method is proposed. First, the grid model is adopted to preprocess the working space of mobile robot. Second, an improved Bi-RRT is proposed to create multi-cluster connections between the starting point and the goal point. Third, the backtracking method is used to generate the initial population based on the multi-cluster connections generated by the improved Bi-RRT. Subsequently, some comparative experiments are implemented where the performances of the improved Bi-RRT-based population initialization method are compared with other population initialization methods, and the comparison results of the improved genetic algorithm (IGA) combining with the different population initialization methods are shown. Finally, the optimal path is further smoothed with the help of the technique of quadratic B-spline curves.FindingsIt is shown in the experiment results that the improved Bi-RRT-based population initialization method is capable of deriving a more diversified initial population with less execution time and the IGA combining with the proposed population initialization method outperforms the one with other population initialization methods in terms of the length of optimal path and the execution time.Originality/valueIn this paper, the Bi-RRT is introduced as a population initialization method into the GACRPP problem. An improved Bi-RRT is proposed for the purpose of increasing the diversity of initial population. To characterize the diversity of initial population, a new notion of breadth is defined in terms of Hausdorff distance between different paths.",

        "abstract": "Abstract   This paper is concerned with the event-triggered robust fusion estimation problem for uncertain multi-rate sampled-data systems with stochastic nonlinearities and the colored measurement noises. Due to the effects of stochastic nonlinearities and parameter uncertainties, a new augmentation approach is proposed by which the multi-rate sampled-data system under consideration is transformed into the single-rate system. In order to eliminate the effect of the colored measurement noises, a measurement model with uncorrected noises is established. Based on the measurement model established, a set of local event-triggered filters is constructed and the upper bounds of the local filtering error covariances at each sampling instant are obtained. By using the Lagrange multiplier method, the local filter parameters are designed such that the upper bound obtained is minimum. For the local state estimates, a new fusion estimation scheme is proposed with the help of covariance intersection (CI) method and the consistency of the proposed CI-based fusion estimation scheme is shown. Finally, an illustrative example is presented to verify the effectiveness of the fusion estimation scheme proposed.",

        "abstract": "The Internet has witnessed rapidly increasing streaming traffic to various mobile devices. In this paper, through analysis of a server-side workload and experiments in a controlled lab environment, we find that current practice has introduced a significant amount of redundant traffic. In particular, for the popular iOS based mobile devices, accessing popular Internet streaming services typically involves about 10%\u201370% redundant traffic. Such a practice not only over-utilizes and wastes resources on the server side and the network (cellular or Internet), but also consumes additional battery power on user's mobile devices and leads to possible monetary cost. To alleviate such a situation without changing the server side or the client side, we design and implement CStreamer that can transparently work between existing mobile clients and servers. We have implemented a prototype and installed on Amazon EC2. Experiments conducted based on this prototype show that CStreamer can completely eliminate the redundant traffic without degrading user's QoS.",

        "abstract": "With the advance of high-speed network technologies, the availability and popularity of streaming media content over the Internet has grown rapidly in recent years. The delivery and caching of streaming media must be handled in a different fashion than that of traditional non-streaming objects such as HTML or image files, because of its distinct characteristics and user viewing patterns. We propose a novel scheme that provides users with the video summary (a number of key-frame images) before they download the file, and options for them to select the starting playback position. We introduce the content analysis service to achieve these functionalities. The video content analysis performs shot boundary detection, key-frame selection, and face detection and tracking. The results of the processing are a segmented video sequence and an XML-based meta-data describing the video content. We also design a caching system that utilizes our video abstraction and summarization technique. Our integrated video delivery and caching system combines content-aware segmentation, prefix caching, prefetching, and cooperative caching. We describe how our scheme can be applied in three proposed caching architectures.",

        "title": "Achieving simultaneous distribution control and privacy protection for Internet media delivery",
        "abstract": "Massive Internet media distribution demands prolonged continuous consumption of networking and disk bandwidths in large capacity. Many proxy-based Internet media distribution algorithms and systems have been proposed, implemented, and evaluated to address the scalability and performance issue. However, few of them have been used in practice, since two important issues are not satisfactorily addressed. First, existing proxy-based media distribution architectures lack an efficient media distribution control mechanism. Without copyright protection, content providers are hesitant to use proxy-based fast distribution techniques. Second, little has been done to protect client privacy during content accesses on the Internet. Straightforward solutions to address these two issues independently lead to conflicts. For example, to enforce distribution control, only legitimate users should be granted access rights. However, this normally discloses more information (such as which object the client is accessing) other than the client identity, which conflicts with the client's desire for privacy protection. In this article, we propose a unified proxy-based media distribution protocol to effectively address these two problems simultaneously. We further design a set of new algorithms in a cooperative proxy environment where our proposed scheme works efficiently and practically. Simulation-based experiments are conducted to extensively evaluate the proposed system. Preliminary results demonstrate the effectiveness of our proposed strategy.",

While various user experiences have been reported from the general user community about their differences, such as battery lifetime, display, and touchpad control, few in-depth reports can be found about their comparative performance when receiving the increasingly popular Internet streaming services. Today, video traffic starts to dominate the Internet mobile data traffic. In this work, focusing on Internet streaming accesses, we set to analyze and compare the performance when Android and iOS devices are accessing Internet streaming services. Starting from the analysis of a server-side workload collected from a top mobile streaming service provider, we find Android and iOS use different approaches to request media content, leading to different amounts of received traffic on Android and iOS devices when a same video clip is accessed. Further studies on the client side show that different data requesting approaches (standard HTTP request vs. HTTP range request) and different buffer management methods (static vs. dynamic) are used in Android and iOS mediaplayers, and their interplay has led to our observations. Our empirical results and analysis provide some insights for the current Android and iOS users, streaming service providers, and mobile mediaplayer developers.",

        "abstract": "The increase of aggregate Internet bandwidth and the rapid development of 3G wireless networks demand efficient delivery of multimedia objects to all types of wireless devices. To handle requests from wireless devices at runtime, the transcode-enabled caching proxy has been proposed and a lot of research has been conducted to study online transcoding. Since transcoding is a CPU-intensive task, the transcoded versions can be saved to reduce the CPU load for future requests. However, extensively caching all transcoded results can quickly exhaust cache space. Constrained by available CPU and storage, existing transcode-enabled caching schemes always selectively cache certain transcoded versions, expecting that many future requests can be served from the cache while leaving CPU cycles for online transcoding for other requests. But such schemes treat the transcoder as a black box, leaving little room for flexible control of joint resource management between CPU and storage. In this paper, we first introduce the idea of meta-caching by looking into a transcoding procedure. Instead of caching certain selected transcoded versions in full, meta-caching identifies intermediate transcoding steps from which certain intermediate results (called metadata) can be cached so that a fully transcoded version can be easily produced from the metadata with a small amount of CPU cycles. Achieving big saving in caching space with possibly small sacrifice on CPU load, the proposed meta-caching scheme provides a unique method to balance the utilization of CPU and storage resources at the proxy. We further construct a model to analyze the meta-caching scheme. Based on modeling results, we propose AMTrac, Adaptive Meta-caching for Transcoding, which adaptively applies meta-caching based on the client request pattern and available resources. Experimental results show that our proposed AMTrac can significantly improve the system throughput over existing approaches.",

        "abstract": "With the wide availability of high-speed network access, we are experiencing high quality streaming media delivery over the Internet. The emergence of ubiquitous computing enables mobile users to access the Internet with their laptops, PDAs, or even cell phones. When nomadic users connect to the network via wireless links or phone lines, high quality video transfer can be problematic due to long delay or size mismatch between the application display and the screen. Our proposed solution to this problem is to enable network proxies with the transcoding capability, and hence provide different, appropriate video quality to different network environment. The proxies in our transcoding-enabled caching (TeC) system perform transcoding as well as caching for efficient rich media delivery to heterogeneous network users. This design choice allows us to perform content adaptation at the network edges. We propose three different TeC caching strategies. We describe each algorithm and discuss its merits and shortcomings. We also study how the user access pattern affects the performance of TeC caching algorithms and compare them with other approaches. We evaluate TeC performance by conducting two types of simulation. Our first experiment uses synthesized traces while the other uses real traces derived from an enterprise media server logs. The results indicate that compared with the traditional network caches, with marginal transcoding load, TeC improves the cache effectiveness, decreases the user-perceived latency, and reduces the traffic between the proxy and the content origin server.",

        "abstract": "Digital video is becoming widely available in compressed form, such as a motion JPEG or MPEG coded bitstream. In applications such as video browsing or picture-in-picture, or in transcoding for a lower bit rate, there is a need to downscale the video prior to its transmission. In such instances, the conventional approach to generating a downscaled video bitstream at the video server would be to first decompress the video, perform the downscaling operation in the pixel domain, and then recompress it as, say, an MPEG, bitstream for efficient delivery. This process is computationally expensive due to the motion-estimation process needed during the recompression phase. We propose an alternative compressed domain-based approach that computes motion vectors for the downscaled (N/2xN/2) video sequence directly from the original motion vectors for the N\u00d7N video sequence. We further discover that the scheme produces better results by weighting the original motion vectors adaptively. The proposed approach can lead to significant computational savings compared to the conventional spatial (pixel) domain approach. The proposed approach is useful for video severs that provide quality of service in real time for heterogeneous clients",

Such small errors can arise due to imperfect recovery from loss, e.g., through error concealment.

Some methods of reducing error amplification is also presented.",

        "title": "A server's perspective of Internet streaming delivery to mobile devices",
        "abstract": "Receiving Internet streaming services on various mobile devices is getting more and more popular. To understand and better support Internet streaming delivery to mobile devices, a number of studies have been conducted. However, existing studies have mainly focused on the client side resource consumption and streaming quality. So far, little is known about the server side, which is the key for providing successful mobile streaming services. In this work, we set to investigate the Internet mobile streaming service at the server side. For this purpose, we have collected a one-month server log (with 212 TB delivered video traffic) from a top Internet mobile streaming service provider serving worldwide mobile users. Through trace analysis, we find that (1) a major challenge for providing Internet mobile streaming services is rooted from the mobile device hardware and software heterogeneity. In this workload, we find over 2800 different hardware models with about 100 different screen resolutions running 14 different mobile OS and 3 audio codecs and 4 video codecs. (2) To deal with the device heterogeneity, transcoding is used to customize the video to the appropriate versions at runtime for different devices. A video clip could be transcoded into more than 40 different versions in order to serve requests from different devices. (3) Compared to videos in traditional Internet streaming, mobile streaming videos are typically of much smaller size (a median of 1.68 MBytes) and shorter duration (a median of 2.7 minutes). Furthermore, the daily mobile user accesses are more skewed following a Zipf-like distribution but users' interests also quickly shift. Considering the huge demand of CPU cycles for online transcoding, we further examine server-side caching in order to reduce CPU cycle demand. We show that a policy considering different versions of a video altogether outperforms other intuitive ones when the cache size is limited.",

        "abstract": "The Internet has witnessed rapidly increasing streaming traffic to various mobile devices. In this paper, we find that for the popular iOS based mobile devices, accessing popular Internet streaming services typically involves about 10% - 70% unnecessary redundant traffic. Such a practice not only overutilizes and wastes resources on the server side and the network (cellular or Internet), but also consumes additional battery power on users' mobile devices and leads to possible monetary cost. To alleviate such a situation without changing the server side or the iOS, we design and implement a CStreamer prototype that can transparently work between existing iOS devices and media servers. We also build a CStreamer iOS App to enable end users to access Internet streaming services via CStreamer. Experiments conducted based on this prototype running on Amazon EC2 show that CStreamer can completely eliminate the redundant traffic without degrading user's QoS.",

        "abstract": "Conventional processing of JPEG or MPEG compressed image or video data involves first decompressing the data and applying the desired processing function, and then the processed data are recompressed for the purposes of transmission or storage. We propose an alternate processing pipeline which involves direct manipulation of the JPEG or MPEG compressed domain representation to achieve the desired spatial domain processing. For direct manipulation in the compressed domain, we develop a discrete cosine transform (DCT)-domain convolution theorem which besides exploiting the sparseness of the DCT-domain representation also exploits the orthogonality and symmetry in the DCT-domain representation. These properties lead to efficient compressed domain-based processing methods unlike their spatial domain counterparts, where such properties are not available. This theorem can be used in a variety of image and video editing functions when the image and video data are available only as a JPEG or MPEG bitstream. We illustrate the use of the DCT-domain convolution theorem in a typical video editing application such as video bluescreen editing",

We show that the selection of quantization step sizes may not have monotonic effects on rate-distortion characteristics in the transcoding sense. In other words, rate-distortion tradeoff for transcoding which operates on an already-compressed source can be different than that for regular encoding which operates on an original source. We show in a generic form that careful selections of the step size can lead to much improved performance for transcoding, especially when comparing to what would have been produced through a direct encoding. We demonstrate this unique rate-distortion characteristic through simulations as well as real transcoding scenario with H.264 sequences.",

        "title": "Modeling and Optimization of Meta-Caching Assisted Transcoding",
        "abstract": "The increase of aggregate Internet bandwidth and the rapid development of 3G wireless networks demand efficient delivery of multimedia objects to all types of wireless devices. To handle requests from wireless devices at runtime, the transcoding-enabled caching proxy has been proposed to save transcoded versions to reduce the intensive computing demanded by online transcoding. Constrained by available CPU and storage, existing transcoding-enabled caching schemes always selectively cache certain transcoded versions, expecting that many future requests can be served from the cache. But such schemes treat the transcoder as a black box, leaving no room for flexible control of joint resource management between CPU and storage. In this paper, we first introduce the idea of meta-caching by looking into a transcoding procedure. Instead of caching certain selected transcoded versions in full, meta-caching identifies intermediate transcoding steps from which certain intermediate results (called metadata) can be cached so that a fully transcoded version can be easily produced from the metadata with a small amount of CPU cycles. Achieving big saving in caching space with possibly small sacrifice on CPU load, the proposed meta-caching scheme provides a unique method to balance the utilization of CPU and storage resources at the proxy. We further construct a model to analyze the meta-caching scheme. Based on the analysis, we propose AMTrac, Adaptive Meta-caching for Transcoding, which adaptively applies meta-caching based on the client request patterns and available resources. Experimental results show that AMTrac can significantly improve the system throughput over existing approaches.",

        "abstract": "Receiving Internet streaming services on various mobile devices is getting increasingly popular, and cloud platforms have also been gradually employed for delivering streaming services to mobile devices. While a number of studies have been conducted at the client side to understand and characterize Internet mobile streaming delivery, little is known about the server side, particularly for the recent cloud-based Internet mobile streaming delivery. In this work, we aim to investigate the Internet mobile streaming service at the server side. For this purpose, we have collected a 4-month server-side log on the cloud (with 1,002 TB delivered video traffic) from a top Internet mobile streaming service provider serving worldwide mobile users. Through trace analysis, we find that 1) a major challenge for providing Internet mobile streaming services is rooted from the mobile device hardware and software heterogeneity. In this workload, we find over 3,400 different hardware models with more than 100 different screen resolutions running 14 different mobile OS and three audio codecs and four video codecs. 2) To deal with the device heterogeneity, CPU-intensive transcoding is used on the cloud to customize the video to the appropriate versions at runtime for different devices. A video clip could be transcoded into more than 40 different versions to serve requests from different devices. 3) Compared to videos in traditional Internet streaming, mobile streaming videos are typically of much smaller size (a median of 1.68 MBytes) and shorter duration (a median of 2.7 minutes). Furthermore, the daily mobile user accesses are more skewed following a Zipf-like distribution but users' interests also quickly shift. Considering the huge demand of CPU cycles for online transcoding, we further examine server-side caching to reduce the total CPU cycle demand from the cloud. We show that a policy considering different versions of a video altogether outperforms other intuitive ones when the - ache size is limited.",

        "abstract": "Streaming media workloads have a number of desirable prop- erties that make them good candidates for caching via proxy systems. The content does not get modified, and access patterns exhibit some lo- cality of reference. However, media files tend to be much larger in size than traditional web pages, and users tend to view video clips only par- tially. Hence, segment-based strategies have been proposed to deliver large streaming media objects via a web-proxy. In this work, we evaluate the performance of such a segment-based streaming proxy using extensive trace driven simulation. We use representative workloads from enterprise media server logs, and evaluate the caching system performance regard- ing different cache sizes, different segment sizes, and different prefetching methods. Our results show that cost-effective caching requires only about 8 - 16 % of the total unique object size as proxy storage. Secondly, a seg- ment size of around 200 Kbytes provides a good trade-off between cache object granularity and transaction overhead. Finally, a lazier prefetching schedule that provides a half-segment look-ahead has a significant perfor- mance gain when compared to a more aggressive one-segment look-ahead scheme.",

        "abstract": "Streaming media objects are often cached in segments. Previous segment-based caching strategies cache segments with constant or exponentially increasing lengths and typically favor caching the beginning segments of media objects. However, these strategies typically do not consider the fact that most accesses are targeted toward a few popular objects. In this paper, we argue that neither the use of a predefined segment length nor the favorable caching of the beginning segments is the best caching strategy for reducing network traffic. We propose an adaptive and lazy segmentation based caching mechanism by delaying the segmentation as late as possible and determining the segment length based on the client access behaviors in real time. In addition, the admission and eviction of segments are carried out adaptively based on an accurate utility function. The proposed method is evaluated by simulations using traces including one from actual enterprise server logs. Simulation results indicate that our proposed method achieves a 30% reduction in network traffic. The utility functions of the replacement policy are also evaluated with different variations to show its accuracy.",

        "abstract": "Massive Internet media distribution demands pro longed continuous consumption of networking and disk band widths in large capacity. Many proxy-based Internet media distribution algorithms and systems have been proposed, implemented, and evaluated to address the scalability issue. However, few of them have been used in practice, since two important issues are not satisfactorily addressed. First, existing proxy-based media distribution architectures lack an efficient media distribution control mechanism. Without protection on the Internet, content providers are hesitant to use existing fast distribution techniques. Second, little has been done to protect client privacy during client accesses. Straightforward solutions to address these two issues independently lead to conflicts. For example, to enforce distribution control, only legitimate users should be granted access rights. However, this normally discloses more information (such as which object the client is accessing) other than the client identity, which conflicts with the client's desire for privacy protection. In this paper, we propose a unified proxy-based media distribution protocol to effectively address these two problems simultaneously. We further design a set of new algorithms for cooperative proxies where our proposed scheme works practically. Simulation results show that our proposed strategy is efficient",

        "abstract": "Many algorithmic efforts have been made to address technical issues in designing a streaming media caching proxy. Typical of those are segment-based caching approaches that efficiently cache large media objects in segments which reduces the startup latency while ensuring continuous streaming. However, few systems have been practically implemented and deployed. The implementation and deployment efforts are hindered by several factors: 1) streaming of media content in complicated data formats is difficult; 2) typical streaming protocols such as RTP often run on UDP; in practice, UDP traffic is likely to be blocked by firewalls at the client side due to security considerations; and 3) coordination between caching discrete object segments and streaming continuous media data is challenging. To address these problems, we have designed and implemented a segment-based streaming media proxy, called SProxy. This proxy system has the following merits. First, SProxy leverages existing Internet infrastructure to address the flash crowd. The content server is now free of the streaming duty while hosting streaming content through a regular Web server. Thus, UDP based streaming traffic from SProxy suffers less dropping and no blocking. Second, SProxy streams and caches media objects in small segments determined by the object popularity, causing very low startup latency, and significantly reducing network traffic. Finally, prefetching techniques are used to pro-actively preload uncached segments that are likely to be used soon, thus providing continuous streaming. SProxy has been extensively tested and we show that it provides high quality streaming delivery in both local area networks and wide area networks (e.g., between Japan and the U.S.).",

        "abstract": "Researchers often use segment-based proxy caching strategies to deliver streaming media by partially caching media objects. The existing strategies mainly consider increasing the byte hit ratio and/or reducing the client perceived startup latency (denoted by the metric delayed startup ratio). However, these efforts do not guarantee continuous media delivery because the to-be-viewed object segments may not be cached in the proxy when they are demanded. The potential consequence is playback jitter at the client side due to proxy delay in fetching the uncached segments, which we call proxy jitter. Thus, for the best interests of clients, a correct model for streaming proxy system design should aim to minimize proxy jitter subject to reducing the delayed startup ratio and increasing the byte hit ratio. However, we have observed two major pairs of conflicting interests inherent in this model: (1) one between improving the byte hit ratio and reducing proxy jitter, and (2) the other between improving the byte hit ratio and reducing the delayed startup ratio. In this study, we first propose and analyze prefetching methods for in-time prefetching of uncached segments, which provides insights into the first pair of conflicting interests. Second, to address the second pair of the conflicting interests, we build a general model to analyze the performance tradeoff between the second pair of conflicting performance objectives. Finally, considering our main objective of minimizing proxy jitter and optimizing the two tradeoffs, we propose a new streaming proxy system called Hyper Proxy. Synthetic and real workloads are used to evaluate our system. The performance results show that Hyper Proxy generates minimum proxy jitter with a low delayed startup ratio and a small decrease of byte hit ratio compared with existing schemes.",

        "abstract": "For downscale (spatial resolution reduction) video transcoding, previous work has shown that motion vectors in the input video can be reused so that the costly motion estimation process can be avoided. Since the derived motion vectors may not be perfectly aligned with the input ones, a drift compensation loop consisting of inverse transform and motion compensation (or transform domain motion compensation) modules is required. However, the motion compensation is always performed based on macroblocks in the full resolution, which makes the full-resolution drift compensation inevitable. This fact renders the drift compensation loop as the next computational bottleneck. Through analytical modeling of the transcoding architectures, we propose a new architecture that employees a submacroblock motion compensation method. This method enables the drift compensation loop to be performed entirely in the reduced resolution. In addition, the memory space required for the architecture is significantly reduced since the full-resolution frame buffers are no longer required. Extensive analysis and experiments show that the proposed system achieves further reduction in computing load comparing to prior systems with minimum quality degradation.",

Our system is designed for efficient delivery of rich media web contents to heterogeneous network environments and client capabilities. The proxies perform transcoding as well as caching in our system. This design choice allows content adaptation to be performed at the edges of the networks. Depending on the connection speed and processing capability of an end user, the proxy transcodes the requested (and possibly cached) video into an appropriate format and delivers it to the user. By serving the transcoded video directly from the proxy, we improve the cache performance. Performance evaluation via simulation is presented. Specifically, simulations using both synthesized traces and real traces derived from enterprise media server logs are conducted. Simulation results indicate that by incorporating transcoding capability at the network edges, the traffic to the content origin server is further reduced.",

        "abstract": "Community streaming is an enhanced form of joint content viewing where a sense of community is reinforced by the addition of interactive visual overlays, controlled in real-time by viewers, on top of a shared video stream. As a concrete example, we describe a community video system called ECHO, where personalized avatars are overlaid on top of a real-time encoded video stream of an Internet game for multicast consumption. Recognizing that only the visual overlays are generated live, we propose schemes that encode and schedule the live and non-live portions of the overlaid video separately in order to exploit the difference in delay sensitivity of the two, leading to video streams that contain two sub-streams with different delay constraints. We show that, in the known channel case, a low complexity ldquoearliest deadline firstrdquo packet scheduling algorithm minimizes receiver buffer delay. We also analyze the case where multiple streams are multiplexed, which allows us to quantify the potential gains of allowing different delay constraints for different sub-streams. We show that a ldquowater fillingrdquo strategy maximizes the total number of streams that can be supported. Simulation results show that the bandwidth necessary to maintain low-latency for visual overlays is reduced by about 40% when our proposed sub-stream approach is used. For multiplexing of multiple streams, our approach can increase the number of supported streams (e.g., a 30% increase when around ten streams are multiplexed).",

        "abstract": "Segment-based proxy caching schemes have been effectively used to deliver streaming media objects. However, this approach does not always guarantee continuous delivery because the to-be-viewed segments may not be cached in the proxy in time. The potential consequence is the playback jitter at the client side due to the proxy delay in fetching these uncached segments, thus we call the problem proxy jitter. Aiming at improving the media delivery quality for segment-based caching schemes, in this paper we propose two simple and effective prefetching methods, namely, look-ahead window based prefetching and active prefetching to address the problem of proxy jitter. We focus on presenting streaming flow analyses on proxy and network resource utilizations and consumptions, performance potentials and limits of the two prefetching methods for different segment-based schemes under different network bandwidth conditions. Our study also provides some new insights into relationships between proxy caching performance and the quality of streaming. For example, we show that the objective of improving the byte hit ratio in a conventional proxy and the unique objective of minimizing the proxy jitter to deliver streaming media objects can have conflicting interests. Trace-driven simulations show the effectiveness of our prefetching methods, and further confirm our analyses.",

        "abstract": "Objective:To compare effects of different intravenous-iron treatment regimens on oxidative stress in chronic renal failure rats.Methods:The chronic renal failure model was established with 5/6 subtotal nephrectomy (5/6 NX) Sprague-Dawley rats. Four weeks after removing the right kidney, rats met the enrolled criteria were randomly divided into total dose intravenous iron group (TDI group), repeated low dose intravenous iron group (rLDI group), CRF control group. We also set up the sham group (Sham group), in which only laparotomy and separation of the kidney peripheral fat vesicle were performed. There were 6 rats in each group, except 4 rats in Sham group. After 6 weeks of treatment, indexes of oxidative stress were investigated. Results: In all three groups of 5/6 NX rats, baseline characteristics such as the proportion of NX, levels of serum creatinine (Scr), blood urea nitrogen (BUN), ratio of urinary protein and creatinine (Upro/cr), hemoglobulin (Hb), hematocrit (Hct), systolic blood pressure (SBP) and body weight (BW) had no significant differences. After 6 weeks of treatment, there was no difference of BW, SBP, Upro/cr, Scr and BUN among the NX groups. Compared with CRF control group, the Hb and Hct were significantly improved in TDI group and rLDI group (P<0.05), but not different between the TDI group and rLDI group (P>0.05). For the concentration of plasma advanced oxidation protein products (AOPP), it was obviously higher in NX groups than it in Sham group, higher in two iron groups than in CRF control group, and also higher in rLDI group than in TDI group(P<0.05); The plasma malonaldehyde (MDA) level was significantly higher than that in Sham group (P<0.05), while it was also higher in rLDI group than in CRF control group and TDI group(P<0.05), and had no difference between TDI group and CRF control group(P>0.05); Compared to Sham group, the serum level of superoxide dismutase (SOD), Catalase (CAT) and total anti-oxidant capacity (T-AOC) was obviously elevated in all three NX groups (P<0.05). The serum level of SOD and T-AOC in two iron groups was not different with those in CRF control group, yet the serum CAT concentration was higher in two iron groups than it in CRF control group (P<0.05), but as for the serum SOD, CAT and T-AOC, there was no significant difference between TDI group and rLDI group (P>0.05). The concentration of plasma Glutathione peroxidase (GSH-Px) was significantly reduced in All NX groups (P<0.05), but there has no difference among the two iron groups and the CRF control group (P>0.05).Conclusion:Introvenous-iron can aggravate oxidative stress in chronic renal failure rats. For adverse effects on oxidative stress, the regimen of total dose intravenous iron is lower than repeated low dose intravein.",

        "abstract": "The aim of this study is to investigate the effects of endogenous vasoactive substances on the occurrence of intradialytic hypertension (IDH) in patients during maintenance hemodialysis. Thirty-four maintenance hemodialysis patients were enrolled in this trial, and 17 of them were diagnosed with IDH (defined as an increase in blood pressure of at least 10\u2009mmHg during or immediately after a hemodialysis session), while 17 age-matched and sex-matched controls without IDH were selected for a retrospective comparison. We collected patients' blood samples before and after a dialysis session and measured the plasma levels of N-terminal fragment brain natriuretic peptide, renin, angiotensin-II, aldosterone (ALD), angiotensin-converting enzyme (ACE), endothelin-1 (ET-1), nitric oxide (NO), norepinephrine (NOR), and adrenomedullin. The post-dialysis serum ET-1 concentrations were significantly higher (4.09\u2009\u00b1\u20092.06 vs. 2.75\u2009\u00b1\u20091.34\u2009pg/mL, P\u2009<\u20090.05), while the post-dialysis ratio of NO to ET-1 was lower (17.79\u2009\u00b1\u20095.65 vs. 24.78\u2009\u00b1\u200912.04, P\u2009<\u20090.05) in IDH patients compared with the control group. Post-dialysis ALD and NOR values were significantly lower (P\u2009<\u20090.01) and ACE levels were significantly higher (P\u2009<\u20090.01) than the pre-dialysis concentrations only in the control and not in the IDH group. All other measured factors did not differ significantly between the groups and between pre-dialysis and post-dialysis determinations. Compared with blood angiotensin-II, ALD, ACE, NOR, adrenomedullin, N-terminal fragment brain natriuretic peptide, and NO status, inappropriately elevated ET-1 plasma concentrations may play a predominant role in the pathogenesis of IDH.",

Methods One hundred and thirteen patients placed temperary hemodialysis catheter in our blood purification center from May 2006 to March 2007 were enrolled.Patients experienced prolonged catheter placement more than half an hour and on bedside blood purification were excluded.Patients were randomly assigned to intervention group(n=60) and control group(n=53),which administrated an antimicrobial lock solution comprised of mixed cefazoline(10 mg/mL) with heparin(45 mg/mL) and lock solution of heparin(50 mg/mL) respetively.Followed up episodes of catheter-related infection.Data analysis was performed with 2-tailed Fisher's exact test,and a Logistic regression was carried out to approach risk factors. Results There was no significant difference(P>0.05) in catheter duration between intervention group [(39.0\u00b146.0)days] and control group [(41.1\u00b157.5)days].Overall 7 patients developed infections including 6 bacteremias and 1 catheter implanting.No exit site infection was observed.Infection incidence was 6.19 events per 100 catheters(6.19%) or 1.55 events per 1 000 catheter days overall(1.55%).Three of fifty-three patients in control group(5.66% or 1.4\u2030) and four of sixty patients in intervention group(6.67% or 1.7\u2030) developed infections with no significant difference(P>0.05).Catheter duration was correlated with infections(P>0.05). Conclusions Cefazoline lock solution was not superior to routine heparin lock in catheter-related infection prophylaxis,but might prevent Gram positive coccus infection.Shortened catheter duration and rigorous sterile operation made for less infections and local application of mupirocin ointment might work.",

There were 498 males and 312 females with an average age of (71\u00b15) years (ranged from 65 to 87 years). Coronary artery bypass graft (CABG) was the most frequently applied (44.0%) method, followed by valve surgery (38.0%) and CABG combined with valve surgery (10.4%). The overall incidence of AKI was 52.3% (424/810). The incidence of AKI requiring renal replacement treatment (AKI-RRT) was 3.2% (26/810). The overall hospital mortality was 3.6% (29/810). The hospital mortality in AKI patients was significantly higher than that in the non-AKI patients (6.4% vs. 0.5%, P<0.01). AKI incidence was highest in cardiac transplantation (100.0%), followed by congenital heart disease operation combined with valve surgery (85.7%) and aorta surgery (77.8%). The hospital mortality was highest in CABG combined with valve surgery (7.2%), followed by aorta surgery (5.6%) and CABG (3.4%). Multivariate logistic regression analysis showed that male sex (OR=2.02, 95%CI 1.35-3.01, P=0.001), preoperative renal dysfunction (serum creatinine>106 \u03bcmol/L, OR=4.63, 95%CI 2.01-10.67, P<0.001), intraoperative cardiopulmonary bypass time (OR=1.01, 95%CI 1.01-1.02, P<0.001), and postoperative administration of vasopressors for hypotension (OR=2.48, 95%CI 1.18-5.21, P=0.002) were the risk factors of AKI after cardiac surgery in elderly patients. Conclusion AKI incidence and hospital mortality after cardiac surgery in elderly patients are very high, and CABG is the most common operation in our hospital. Heart transplantation, congenital heart disease treatment combined with valve surgery, and aorta surgery are the high-risk opeartions for AKI.",

        "abstract": "To compare the efficacy and safety of goal-directed renal replacement therapy(GDRRT) and daily high volume hemofiltration (dHVHF) in the treatment of acute kidney injury (AKI) after cardiac surgery.Clinical data from 128 patients received either GDRRT (n = 64) or dHVHF (n = 64) for AKI after cardiac surgery were analyzed retrospectively. parameters examined included: urea nitrogen, serum creatinine (SCr, before and after treatment), heart rate, mean artery pressure (MAp, recorded within 72 hours after the initiation of renal replacement therapy). The hospital mortality, day-28 mortality, renal function recovery rate, and the incidence of adverse events in the two groups were also compared.The hospital mortality was 43.75% for both GDRRT and dHVHF treated patients (group). The day-28 mortality in GDRRT group were slightly lower, but the difference was not significant (43.75% vs. 57.81%, P = 0.055). Also no significant difference was found between the two groups in hospital stay. The patients received dHVHF had longer intensive care unit (ICU) stay (hours) and duration of mechanical ventilation (days) as compared to the patients received GDRRT [356.5 (176.3, 554.6) vs. 238.3 (119.6, 440.9), P = 0.023; 8.0 (5.0, 16.0) vs. 6.0 (3.0, 13.5), P = 0.042]. The logistic regression analyses showed that complete renal function recovery rate in GDRRT group was significantly higher (39.1% vs. 18.8%, P < 0.01). The partial renal function recovery rate in GDRRT group was slightly lower but not statistically different from dHVHF group (3.1% vs. 9.4%, P > 0.05). In dHVHF group, the maximum SCr during the treatment, and the SCr before discharge were both significantly higher than GDRRT group (\u03bcmol/L: SCr maximum 559.0 \u00b1 236.0 vs. 440.4 \u00b1 192.0, SCr before discharge 381.4 \u00b1 267.0 vs. 271.2 \u00b1 164.4, both P < 0.01). No significant difference was found between the two groups in incidence of hypotension (35.9% vs. 37.5%) and MAP (mm Hg, 1 mm Hg=0.133 kPa, 82 \u00b1 13 vs. 81 \u00b1 15) 72 hours into the therapy (both P > 0.05). The incidence of tachycardia, and incidence of blood coagulation were both higher in dHVHF group (78.1% vs. 59.4%, 35.9% vs. 20.3%, both P < 0.05). However, the hospitalization expense (thousand yuan) was significantly higher for dHVHF group (15.00 \u00b1 2.80 vs. 9.85 \u00b1 3.00, P < 0.01).For patients with post-cardiac surgery AKI, GDRRT and dHVHF are very similar in terms of short-term survival rate and safety. But GDRRT is superior for renal function recovery and cost saving.",

Methods A retrospective study of elderly patients with AKI after cardiac surgery from January 2009 to January 2011 was carried out. Patients were divided into AKI group and non-AKI group and followed up for 2 years. The survival rate and the incidence of advanced chronic kidney disease were analysed. Results 393 patients were enrolled and 214( 55. 4%) were patients with AKI( 148 cases of AKI-1,34 cases of AKI-2 and 32 cases of AKI-3). The patients in AKI group were significantly older than those in non-AKI group( 71. 1 \u00b1 4. 6 vs 69. 9 \u00b1 4. 3,P < 0. 01),and the proportion of male in AKI group was significantly higher than that in non-AKI group( 71. 9% vs 55. 9%,P < 0. 01); 1 year cumulative survival in AKI was 78. 0%,which was significantly lower than non-AKI group( P < 0. 01). One year cumulative survival rate of AKI-1 to AKI-3 was 85. 8%,64. 7%,62. 5%,and two-years cumulative survival rate of AKI-1 to AKI-3 was 79. 1%, 46. 9% and 55. 9%( P < 0. 01); The incidence of advanced CKD in AKI patients after two-year follow up was significantly higher than that in non-AKI group( 7. 9% vs 0. 0%,P < 0. 01). Then the incidence of advanced CKD in AKI-1 to AKI-3 patients after 2 years was 4. 1%,8. 8% and 25. 0%( P < 0. 01). Conclusions The elderly patients after cardiac surgery were at high risk of AKI. The incidence and severity of AKI were associated with the long-term survival and renal recovery.",

Methodology:Blood samples were obtained from one hundred thirty MHD patients before undergoing hemodialysis.The serum NT-proBNP was measured by electro-chemoluminiscence immunoassay.Spearman correlation and linear regression were used to assess the correlation between NT-proBNP and other parameters.Receiver operating characteristic (ROC) curves were used to assess the relationship with NT-proBNP,cardiac troponin T(cTnT),high-sensitive C reactive protein (hsCRP) and left ventricular hypertrophy. Results:The levels of serum NT-proBNP were significantly higher in MHD patients,the patients with CVD had more higher serum NT-proBNP levels than that those without CVD(4 649 [2 920-14 069]pg/ml vs 3006 [1 457-7 478]pg/ml,P=0.002).In all MHD patients,serum NT-proBNP was correlated positively with age(\u03c1=0.195,P=0.026),systolic blood pressure (\u03c1=0.306,P=0.001),hsCRP (\u03c1=0.228,P=0.009),cTnT (\u03c1=0.448,P<0.001),carotid artery intima-media thickness (\u03c1=0.244,P=0.021) and left ventricular mass index (\u03c1=0.537,P<0.001); while negatively with body mass index (\u03c1=-0.153,P=0.031),pre-albumin (\u03c1=-0.304,P<0.001),triglyceride (\u03c1=-0.246,P=0.014),total cholesterol (\u03c1=-0.265,P=0.008),low density lipoprotein cholesterol(\u03c1=-0.254,P=0.012)and left ventricular ejection fraction(\u03c1=-0.194,P=0.040).Linear regression analysis showed that cTnT (\u03b2=0.463,P=0.001),left ventricular mass index (\u03b2=0.324,P=0.003) and systolic blood pressure(\u03b2=0.208,P=0.008) were independently associated with NT-proBNP.ROC curves analysis showed that the relationship between NT-proBNP and left ventricular hypertrophy was more closely than that cTnT and hsCRP.

She failed medical managements and lost her renal graft just after the kidney transplantation due to acute rejection. Although surgical parathyroidectomy was effective, the parathyroid hormone level became extremely high again due to recurrent hyperparathyroidism. It is possible that such patient could survive long-term with dialysis, but prevention of severe SHPT is the most important.",

        "abstract": "Objective To analyze the death cause and risk factor for the patients with acute kidney injury (AKI) requiring renal replacement therapy (RRT) after cardiac surgery. Methods Clinical data of the patients who developed AKI and received RRT after cardiac surgery from January 2002 to April 2011 in Zhongshan Hospital were retrospectively analyzed. Cause of death was classified according to Montgomery diagnostic standard. Results A total of 172 patients were enrolled in this study. There were 117 males and 55 females with an average age of (55\u00b114) years (ranged 18 to 83 years). The overall mortality was 43.6% (n=75). Death causes included heart failure (48%), respiratory failure (22.7%), hematological failure (9.3%), severe sepsis (8.0%), renal failure (6.7%), and liver failure (5.3%). The patients who died of heart failure had low cardiac output syndrome (LCOS) after surgery. The incidence of LCOS in death group was significantly higher than that in survivor group (56.0% vs. 19.6%, P<0.01). The percentage of fluid overload in death group was significantly higher than that in survivor group at early stage after surgery and in ICU (45.3%[34/75] vs. 21.6%[21/97], 68.0%[51/75] vs. 46.4%[45/97], P<0.01). Single Logistic regression analysis showed that LCOS (OR=5.2, 95%CI: 2.7-10.3), fluid overload in ICU (OR=2.0, 95%CI: 1.1-3.8) and at early stage after surgery (OR=3.0, 95%CI: 1.5-5.8), severe sepsis (OR=4.3, 95%CI: 1.8-10.1), and intraoperative cardiopulmonary bypass time (OR=1.005, 95%CI: 1.001-1.010) were risk factors of death in AKI-RRT patients after cardiac surgery (P<0.05, 0.01). Multivariate Logistic regression analysis showed that LCOS was the only independent risk factor of death (OR=4.2, 95%CI: 2.0-8.5, P<0.01). Conclusion Heart failure is the main cause of death for the patients who developed AKI and required RRT after cardiac surgery. LCOS is the predominant independent risk factor for death. It is recommended that cardiac pump function should be improved after surgery.",

        "abstract": "To investigate the risk factors and prognosis influential factors of acute kidney injury (AKI) after cardiac surgery.The clinical data of patients who were hospitalized and underwent cardiac surgery from April 2009 to May 2011 were collected prospectively. Demographic characteristics, types of surgeries, preoperative renal function, pre- and intra-operative conditions and clinical outcomes, etc were recorded.A total of 4007 patients underwent cardiac surgery were recruited. The overall incidence of AKI was 31.2% (1250/4007). The incidence of AKI requiring renal replacement treatment (AKI-RRT) was 2.6% (104/4007). The overall hospital mortality was 1.9% (77/4007), and was significantly higher in AKI group than in non-AKI group (5.4% vs 0.3%, P < 0.01). The hospital mortality of AKI-RRT group was 36.5% (38/104). Grouped by type of surgery, cardiac transplantation had the highest AKI incidence (73.0%) and highest in-hospital mortality (18.9%), followed by coronary artery bypass grafting (CABG) combined with valve surgery (AKI incidence 57.8%, in-hospital mortality 6.1%) and aneurysm surgery (AKI incidence 52.0%, in-hospital mortality 5.5%). Multivariate logistic regression analysis showed that man, age, BMI, hypertension, chronic heart failure, pre-operative serum creatinine (SCr) > 106.0 \u00b5mol/L, intra-operative cardiopulmonary bypass time, intra-operative hypotension and aneurysm surgery were the risk factors of AKI after cardiac surgery. Multivariate logistic regression analysis showed that pre-operative SCr > 106.0 \u00b5mol/L and intra-operative hypotension were independent risk factors of renal recovery after cardiac surgery while recovery of urine output was the favorable factor.Cardiac surgery usually induces high AKI incidence and poor prognosis, which closely associated with many risk factors in peri-operative stage. The incidence of AKI is related to a number of perioperative risk factors. Heart transplantation, aneurysm surgery, CABG combined valve surgery are high risk surgeries.",

Two patient groups, which comprised 70 patients who received DHF from January 2002 to September 2008 and 70 patients treated with GDRRT from October 2009 to September 2010 were pair-wise compared regarding clinical outcomes, as well as the incidence of adverse events.In-hospital and 30-day mortality rates were 45.7% and 41.4% in the GDRRT and 48.6% and 54.3% in the DHF group, respectively, but without statistically significant differences. GDRRT patients needed statistically significantly shorter hospital and intensive care unit (ICU) stays, less frequent RRT, and shorter RRT sessions, whereas, of 11 analyzed renal outcome parameters, 6 values, including percentage of complete renal recovery and time for complete renal recovery, were significantly superior in the GDRRT group at the time of discharge. There was no significant difference in the incidence of adverse events within the initial 72 treatment hours between the 2 groups. Hospitalization expenses were less in GDRRT group than in DHF group.The GDRRT approach is superior to DHF for improving renal outcome, as well as reducing the time and cost of RRT therapy, for cardiac surgery AKI patients.",

        "abstract": "Indoxyl sulfate, a protein-bound uremic toxin, may be associated with cardiovascular events and mortality in patients with CKD. This study aimed to investigate the relationship between indoxyl sulfate and heart failure in patients on hemodialysis.Patients on hemodialysis for >6 months were enrolled within 6 months. Patients with congestive heart failure, angina pectoris, acute myocardial infarction, cerebral infarction, or cerebral hemorrhage within 3 months before the study or those <18 years old were excluded. The primary end point was first heart failure event during follow-up.In total, 258 patients (145 men) with a mean age of 57.0 \u00b1 14.6 years old were enrolled. Median plasma indoxyl sulfate level was used to categorize patients into two groups: the low-indoxyl sulfate group (indoxyl sulfate \u2264 2.35 \u03bcg/ml) and the high-indoxyl sulfate group (indoxyl sulfate >32.35 \u03bcg/ml). Then, patients were prospectively followed up for a median of 48.0 (interquartile range: 33.5-48.0) months. During follow-up, 68 patients experienced episodes of first heart failure. Kaplan-Meier analysis revealed the incidence of first heart failure event in the high-indoxyl sulfate group was significantly higher than in the low-indoxyl sulfate group (log rank P<0.001). Cox regression analysis showed indoxyl sulfate was significantly associated with first heart failure event (indoxyl sulfate as the continuous variable: hazard ratio, 1.02; 95% confidence interval [95% CI], 1.01 to 1.03; P=0.001; indoxyl sulfate as the dichotomous variable: hazard ratio, 3.49; 95% CI, 1.97 to 6.20; P<0.001). After adjustment for other confounding factors, the results remained significant (indoxyl sulfate as the continuous variable: hazard ratio, 1.04; 95% CI, 1.02 to 1.06; P<0.001; indoxyl sulfate as the dichotomous variable: hazard ratio, 5.31; 95% CI, 2.43 to 11.58; P<0.001).Plasma indoxyl sulfate was associated with first heart failure event in patients on hemodialysis. Whether indoxyl sulfate is only a biomarker or involved in the pathogenesis of heart failure in hemodialysis warrants additional study.",

        "abstract": "Objective To assess the risk factors for intradialytic-hypotension (IDH) among maintenance hemodialysis (MHD) patients and to provide clinically useful information for the prevention and treatment of IDH. Methods We recruited 293 patients who underwent hemodialysis during Jan. 2009 to Dec. 2010. Intradialytic blood pressure was monitored in a 3-month period. IDH was defined as an event characterized by a sudden drop of systolic BP more than 20mmHg or of mean artery pressure (MAP) more than 10mmHg. Logistic regression analysis was used to assess the risk factors for IDH. Results The incidence rate of IDH was 39.9%. In the 293 patients, 176 patients with <1/10 IDH events/3 months (defined as non-IDH) were served as controls, 80 patients were found to have \u2265 1/10 but \u2264 1/3 IDH events/3 months (occasional IDH), and 37 patients with > 1/3 IDH events/3 months (frequent IDH). We used ultrafiltration volum/body weight (UFV/W) to correlate with IDH, and the area under the ROC curve (AUC) of IDH was 0.706 (95% CI: 0.64\uff5e0.77, P<0.01). When the cut-off value of UFV/W was set at 4.33%, the sensitivity for IDH was 53.2% and the specificity for IDH was 76.5%. Multivariate regression analysis showed that age, ultrafiltration rate, serum NT-proBNP, serum albumin, and serum 2MG were associated with IDH among MHD patients. Conclusion Elderly, higher ultrafiltration rate, higher levels of serum NT-proBNP and 2MG, and hypoalbuminemia are independent risk factors for IDH among MHD patients.",

Methods A total of 111 ESRD patients were divided into two groups, 25 patients with previous abdominal or pelvic surgery(group A), and 86 patients without history of abdominal or pelvic operation(group B). The short- and long-term complications of the procedures of peritoneal dialysis catheter\u2019s placement were observed. Results The rates of complications after catherter placement in group A and B were as following: wound haematoma 8.0% vs 3.5%, catheter malposition 0 vs 2.3%, pericatheter leakage 4.0% vs 3.5%, abdominal pain 12.0% vs 9.3%, exit site infection 0 vs 0, peritonitis 16.0% vs 12.8%, catheter blockage 0 vs 2.3% and scrotal swelling 0 vs 1.2%. However, no statistically difference was observed between these two groups. Conclusions Previous minor to moderate abdominal surgery does not have a major impact on the complication after peritoneal dialysis catheter\u2019s placement via open technique. Preoperative evaluation of intra-abdominal adhesions and careful intraoperative manipulation are of great importance.",

Results showed that samples with x = 0.46-0.52 have a coexisted crystal structure with both orthorhombic and tetragonal phases, separating orthorhombic phase on both sides of this composition and corresponding to a polymorphic phase transition near room temperature. In this region, enhanced electrical properties were obtained. The approach of two-step sintering obviously broadened the sintering temperature range of the ceramics and further improved piezoelectric properties by \u223c10%, indicating it is a promising way for fabricating (K, Na)NbO 3-based ceramics. Moreover, all studied samples showed good resistance to thermal depoling up to temperatures close to their Curie points, suggesting that this system should be an attractive lead-free material for piezoelectric applications. \u00a9 2012 Elsevier B.V.

The correlation between the dielectric breakdown performance and the activation energy was studied by the measurements of the dielectric breakdown strength and impedance spectroscopy. It was found that the change in the Ba/Na ratio in the glass notably modified the dielectric properties. The increase of Ba/Na ratio promoted the crystallization of Ba 2NaNb5O15 from the glass matrix that has a high dielectric constant. When the ratio of Ba/Na was 2, the optimization of dielectric breakdown performance and dielectric constant was obtained. The as-devitrified (4BaO, Na2O)-Nb2O5-SiO 2 glass-ceramic exhibits a large dielectric breakdown strength of 864 kV/cm with a stable dielectric constant of about 150 over the temperature range of -50 C to 100 C.",

        "abstract": "Calcium bismuth niobate (CaBi 2Nb 2O 9, CBN) is a high Curie temperature (T C=930\u00b0C) ferroelectrics material and a promising candidate for high-temperature piezoelectric applications. This study focuses on the effect of the grain size on the electric properties and thermal stability of CBN ceramics. The CBN ceramics with different grain sizes were prepared by three different sintering methods: normal sintering, two-step sintering, and hot pressing sintering. Result shows that a strong dependence of piezoelectric properties on the grain size. The d 33 of two-step sintering samples with 1.4 \u03bcm grain size is 13.5 pC/N which is more than double of that the normal sintering sample with only about 6 pC/N. With the grain size increasing, the unit-cell volume of CBN ceramic is expanded and the T C shift to higher temperature for enhanced stability of the orthorhombic structure. The thermal stability of piezoelectric properties is enhanced from room temperature to near Curie temperature when the grain size is larger than that of 4.3 \u03bcm. However, the thermal stability is decreased with decreasing of the grain size since internal stresses provide an additional driving force that assists the thermal depolarization. \u00a9 2012 The American Ceramic Society.",

        "abstract": "Abstract   Grain size effect is one of the most important issues to develop next-generation functional devices. In this work, we firstly provide a systematic investigation on the grain size dependent physical properties based on a flexible (Na 0.5 Bi 0.5 )TiO 3 -xSrTiO 3  (NBT-xST) system with multifunctionality. The NBT-20ST, -26ST and -35ST with multiple phase boundaries/structures were chosen as the studied compositions. The densified ceramics with a series of grain sizes were successfully fabricated by normal and two-step sintering method. For NBT-20ST and -26ST compositions, the coarse grain size is more favorable for improving the direct (small-signal  d  33 ) and converse (large-signal  d  33  \u2217 ) piezoelectricity. The critical grain size of NBT-20ST and -26ST compositions for improving  d  33  and  d  33  \u2217  is both around 1 \u03bcm. Rayleigh analysis and local PFM mapping indicate that the high  d  33  in coarse-grained NBT-20ST samples originates from the increased extrinsic contribution and easier domain wall motion, while the large  d  33  \u2217  in coarse-grained NBT-26ST samples stems from the polarization enhancement through a linear electrostrictive effect. For NBT-35ST composition, an improved energy storage performance with high recoverable energy density over 1 J/cm 3  was achieved in a 0.56 \u03bcm-sized sample owing to a large fraction of low-polarizability grain boundary layer. This study opens up a new way for designing novel lead-free multifunctional piezoceramics with superior electromechanical properties.",

        "abstract": "Ba 0.6 Sr 0.4 TiO 3\u2212 x MgCo 2 (VO 4 ) 2 ceramics with x = 0, 0.5, 1.0, 2.0, and 5.0 wt% was fabricated via conventional solid-state reaction process.

Keywords D. BaTiO 3 and titanates Structure Microwave dielectric properties 1 Introduction In recent years, there is a rapidly growing demand for electrically tunable microwave devices, such as voltage tunable phase shifters, oscillators, and filters, for advanced radar and communication devices [1\u20135] . Many efforts have been focused on the ferroelectric Ba x Sr 1\u2212 x TiO 3 (BST) systems. BST ceramics are considered to be one of the most promising candidates for microwave elements because of their high dielectric nonlinearity and adjustable dielectric properties by tuning ratio of Sr and Ba. However, the relatively large dielectric insertion loss at high frequency region restricts its practical applications. Both low loss and large tunability techniques have been adopted to modify the microwave dielectric properties of this ferroelectric ceramics by introducing small content of dopants. This approach is found to dramatically alter the properties of ferroelectric materials. A recent study [6] showed that Mg 3\u2212 x Co x (VO 4 ) 2 ceramics with x = 2, prepared by a conventional solid-state reaction process, had a high Q \u00d7 f value at low sintering temperature (below 950 \u00b0C) with optimum microwave dielectric properties. These properties offer us a good opportunity to use MgCo 2 (VO 4 ) 2 (MCV) as a dopant into the BST ceramics. This dopant is supposed to cause a relatively low dielectric constant to improve the microwave dielectric properties of BST ceramics. It is logical to explore MCV doped composite ceramics to modify the electrical properties of BST ceramics. In present study, we prepared BST\u2013MCV composite ceramics and evaluated its electric properties. Moderate dielectric constant, high dielectric tunability and low dielectric loss were obtained. These optimum properties show that the composite ceramics are promising materials for application in tunable microwave devices. 2 Experimental The nominal Ba 0.6 Sr 0.4 TiO 3 (BST) powder was prepared by a solid-state reaction method. Appropriate amounts of BaTiO 3 (99.9%) and SrTiO 3 (99.9%) powders were dried at 500\u2013700 \u00b0C before mixing together and then ball-milled in a nylon jar with zirconia balls. The mixture was fired at 1100 \u00b0C for 4 h. X-ray diffraction (XRD) patterns showed that all the peaks belong to BST which indicated the accomplishment of the reaction. The MgCo 2 (VO 4 ) 2 powder was also prepared by the solid-state reaction method. The powders of MgO (99.9%), Co 2 O 3 (99%) and V 2 O 5 (98.0%) were used as starting materials. These materials were weighed and mixed by ball milling for 8 h. After drying, the mixture was calcined at 700 \u00b0C for 20 h. The phase of the calcined powders was determined by X-ray diffraction and identified as a single phase of MgCo 2 (VO 4 ) 2 . The calcined BST powders with 0.5, 1.0, 2.0 and 5.0 wt% MCV, named as BST\u2013MCV\u20130.5 wt%, BST\u2013MCV\u20131.0 wt%, BST\u2013MCV\u20132.0 wt% and BST\u2013MCV\u20135.0 wt%, were mixed again. The mixture was granulated and pressed into disk shaped pellets. The pellets were sintered at 1275 \u00b0C for 4 h with a heating rate of 3 \u00b0C/min. Phase structures of sintered samples were analyzed by X-ray diffraction (XRD) (Model, D8 ADVANCE, Bruker, Germany). The patterns were recorded between 20\u00b0 and 80\u00b0 with 2 \u03b8 increments of 0.02\u00b0. The microstructure was observed on the free surfaces of the specimens using scanning electronic microscopy (SEM) (Model, JSM EMP-800, JEOL, Tokyo, Japan). The densities of the sintered ceramics were measured using the Archimedes method. Ag electrodes were painted on the major faces of thinned ceramic disks and sintered at 600 \u00b0C for electrical characterization. The dependence of the dielectric constant and loss on temperature from \u2212165 \u00b0C to 130 \u00b0C at 10 kHz was measured using a high-precision LCR meter (HP 4284A, Agilent, Palo Alto, CA). Tunability was tested at 10 kHz and 20 \u00b0C up to maximum bias voltage of 30 kV/cm using a Keithley 2410 (Cleveland, OH) high voltage source coupled with a TH2816 LCR (Changzhou, China) analyzer. The dielectric constant and Q values at microwave frequencies were measured using the Hakki-Coleman dielectric resonator method with a network analyzer (HP 8753E, Agilent, Palo Alto, CA) combining a resonating cavity. The values of \u025b and tan \u03b4 were calculated from the resonant frequency and the geometric dimensions of the samples using Hakki\u2013Coleman program. 3 Results and discussion Fig. 1 shows the XRD patterns of all the samples. It is found that new phases Ba 3 (VO 4 ) 2 is detected as the value of x increased to 5.0 wt% and the intensities of diffraction peaks increase with increasing of MCV content. In order to clarify the effect of MCV addition on the microstructure of BST ceramics, the morphological changes of the BST ceramics were investigated. Fig. 2 shows the free surface micrographs of samples with different amounts of MCV doping. Compared with pure BST ceramic, the addition of MCV obviously increased the density and enhanced the grain growth of BST. For BST with addition of 0.5 wt% MCV, some abnormal large cubic grains appeared. This may be due to the effect of the low melting point of MgO\u2013V 2 O 5 system on the grain growth behavior of the ceramics. In the binary phase diagrams of MgO\u2013V 2 O 5 systems, it was reported that the Mg 3 (VO 4 ) 2 compounds decomposed into the liquid phase at the temperature of 1074 \u00b0C [7] . This low-melting-point additive diffuses into the grain boundary consequently allows BST grains grow rapidly with cubic shape corresponding to their crystal structure. When the content of MCV exceeded 1.0 wt%, the number of abnormal grain increased and more pores appeared, as a result the density of the sample decreased. The relative density of the BST ceramics with various contents of MCV is approximately 91.2% for BST-pure, 95.5% for BST\u2013MCV\u20130.5 wt%, 93.2% for BST\u2013MCV\u20131.0 wt%, 92.3% for BST\u2013MCV\u20132.0 wt% and 90.7% for BST\u2013MCV\u20135.0 wt%, respectively. This is in good agreement with the observations reported in the literature [8] . Fig. 3 shows the dielectric constant and dielectric loss of sintered BST with different amount of MCV as a function of temperature. The dielectric constant of BST was decreased with increasing of MCV content. The Curie temperature shifted to low temperature slightly. The shift of the Curie temperature may be due to the substitution of V and Co [9] . The ionic radii of Ba, Sr, Ti and O are summarized as follows: A-site (12 coordinates): Ba 2+ = 1.61 \u00c5, Sr 2+ = 1.58 \u00c5. B-site (6 coordinate): Ti 4+ = 0.605 \u00c5. Co 3+ = 0.55 \u00c5 and V 5+ = 0.58 \u00c5 [10] . V 5+ is too small for the A-site and would occupy the B-site with Ti 4+ [11] . Accept Co 3+ replaces Ti 4+ in the BST lattice and a doubly ionized oxygen vacancy is formed, which lead to a \u201cbreak\u201d of the cooperative vibration of Ti\u2013O chains. This \u201cbreak\u201d is responsible for the low T c of the doped BST [12] . The dielectric loss of BST with a small amount of MCV was higher than that of pure BST, and all samples have loss tangent values less than 0.005 at 10 kHz and room temperature. Fig. 4 shows the dielectric constant versus electric field characteristics at 10 kHz and 20 \u00b0C. All samples added MCV have loss tangent values less than 0.005 at 10 kHz and room temperature (not shown in Fig. 4 ). The dielectric properties and calculated tunability are summarized in Table 1 . The tunability for all samples with MCV additions kept between 38.3% and 47.2%. Dielectric materials should have not only high tunability but also high Q (=1/tan \u03b4 ) value or low loss tangent for practical applications of tunable devices. The microwave dielectric data are presented in Table 1 . It can be seen that the dielectric constants of all samples were decreased at microwave frequencies compared with those at low frequencies (below 1 MHz). It was reported that the Q value of pure BST sintered at 1400 \u00b0C for 4 h was about 133 under 0.632 GHz [13] . The Q values of all samples were varied with different amount of additives. There are two kinds of microwave dielectric loss, including intrinsic loss and extrinsic loss [14] . The lattice vibration modes cause the intrinsic losses while the extrinsic losses were dominated by grain sizes, oxygen vacancies, second phases, densification/porosity, etc. Compared with pure BST, the Q value of BST\u2013MCV\u20130.5 wt% sample was increased to 267 near 1 GHz. The increase of Q value of BST ceramics with MCV should attribute to the higher densification and the decrease of oxygen vacancies which increased the anharmonic interaction. Since V 5+ act as a donor, the reaction can be represented by the following formula [14] . (1) V 2 O 5 + V o \u2033 \u2192 2V Ti \u2032 + 5O o Further increasing the amount of MCV in BST ceramics would result in the decrease of Q value. The lower Q value of BST ceramics for the further addition of MCV is attributed to the increase of abnormal grain growth (as observed in Fig. 2 ) and excessive compensation. 4 Conclusions It is found that a small addition of MgCo 2 (VO 4 ) 2 to Ba 0.6 Sr 0.4 TiO 3 can increase the density of BST. This attributed to the formation of MgO\u2013V 2 O 5 liquid phase. The addition of a small amount of MCV can effectively promote the microwave dielectric properties of BST. For BST ceramics with 0.5 wt% MCV addition, the dielectric loss keeps around 0.0020 and the tunability is above 35%. The Q value is 267 at the frequency of 0.925 GHz.

The temperature and composition-dependent strain behavior, dielectric, ferroelectric (FE), piezoelectric, and pyroelectric properties have been systematically investigated to develop lead-free piezoelectric materials with large strain response for actuator application. As the BAT content increased, the FE order is disrupted resulting in a degradation of the remanent polarization, coercive field, and the depolarization temperature (T d). A large strain of 0.36% with normalized strain d 33* = 448pm/V was obtained for the optimum composition x = 0.045 at room temperature. The bipolar and unipolar strains for the compositions x = 0.035 and x = 0.04 reach almost identical maximum values when the temperature is in the vicinity of their respective depolarization temperature (Td). The Raman-spectra analysis, macroscopic properties, thermal depolarization results, and temperature-dependent relationships of both polarization and strain demonstrated that the origin of the large strain response for this investigated system is attributed to a field-induced relaxor to FE phase transformation. \u00a9 2012 The American Ceramic Society.",

The highest degree of orientation (Lotgering factor f = 94%) was achieved in samples with template content of 20 wt%. However, these samples did not exhibit enhanced strain response due to the composition deviation induced by the interdiffusion of BiT into the matrix composition. Instead, maximum strain value of 0.45% was observed in the textured sample with 5 wt% template, which was 50% higher than that of random ceramics and comparable with some PZT-based anti-ferroelectric ceramics, suggesting the textured ceramics could be a very promising lead-free piezoelectric material for application in electromechanical devices. \u00a9 2012 The American Ceramic Society.",

        "abstract": "Dielectric properties of Ba 0.5 Sr 0.5 TiO 3 \u2013 x Zn 2 P 2 O 7 ( x = 1, 3, 5, 10, 15 wt%) composite ceramics, which were prepared by solid-state reaction process, were intensively investigated. The results showed that the Curie temperature ( T c ) of composites gradually shifted to lower temperature (\u2212140 \u00b0C) with increasing the content of Zn 2 P 2 O 7 , and the dielectric constant were tuned effectively from 2020 to 107, while maintaining a relatively high tunability. Zn 2 P 2 O 7 additions remarkably inhibited the grain growth of Ba 0.5 Sr 0.5 TiO 3 phases, and improved the breakdown strength of samples up to 385 kV/cm. The sample with x = 10 wt% exhibited good dielectric properties ( \u025b r = 290, tg \u03b4 = 0.0006, T = 20.5%, BDS = 297 kV/cm). Meanwhile Zn 2 P 2 O 7 addition also made the T c far away from the room temperature, which reduced the sensitivity of the dielectric constant to temperature change and simultaneously improved the stability of materials. Keywords A. Powders: solid state reaction A. Grain growth C. Strength Tunability 1 Introduction Ba x Sr 1\u2212 x TiO 3 (BST) solid solutions are widely studied due to their potential applications in tunable devices, such as the phase shifters, delay lines, voltage controlled oscillators, and tunable capacitors [1,2] . However, high permittivity and sintering temperature (\u22651350 \u00b0C) of pure BST ceramics restrict its applications [3] . Therefore, the optimal trade-off of the correlated dielectric parameters of BST is very critical, namely keeping tunability ( T ) as high as possible with low dielectric constant ( \u025b r ), and low loss tangent (tg \u03b4 ). Therefore, microwave dielectric materials with low loss, low dielectric constant (e.g. MgO [4] , Mg 2 TiO 4 [5] , MgAl 2 O 4 [6] , etc.) are always deliberately introduced to BST matrix in order to overcome the drawbacks mentioned above. Such a method effectively tailors dielectric properties of pure BST. Besides, low DC breakdown strength (BDS < 60 kV/cm) of pure Ba x Sr 1\u2212 x TiO 3 (0.4 \u2264 x \u2264 0.6) ceramics in air restricts the stability of materials under high applied electric field. The risk of dielectric breakdown results in the irreversible degradation of ferroelectric materials or mechanical failure [7] . Although it was reported that some glasses [8,9] or other sintering aids [10] can improve the breakdown strength (BDS) of BaTiO 3 -based ceramics prepared by the solid-state reaction, the tunability smartly degraded. Therefore, optimization of the correlated parameters and improvement of the stability of materials (e.g. the breakdown strength and temperature stability) while keeping an acceptable tunability have become important issues in the field of tunable devices. In this paper, the Zn 2 P 2 O 7 ( \u025b r = 7.5, Qxf = 50,000) of microwave dielectric materials with lower sintered temperature (875 \u00b0C) was chosen as sintering additive and uniformly distributed into Ba 0.5 Sr 0.5 TiO 3 matrix [11] . The dielectric breakdown strength and dielectric properties of composite ceramics were investigated systematically. 2 Experimental BaTiO 3 (99.9%), SrTiO 3 (99.9%), and ZnO (99%), (NH 4 ) 2 HPO 4 (98%) were used as raw materials to synthesize pure Ba 0.5 Sr 0.5 TiO 3 and Zn 2 P 2 O 7 powders at 1100 \u00b0C and 650 \u00b0C via the conventional solid-state reaction, respectively. The calcined Zn 2 P 2 O 7 powders were added into Ba 0.5 Sr 0.5 TiO 3 powders in a proper weight fractions (1, 3, 5, 10, 15 wt%). The mixed powders were ball-milled using the alcohol and zirconia balls grinding media for 24 h. And then, the dried powers, which were added with 8 wt% polyvinyl alcohol binder, were uniaxially pressed into disk-shaped pellets with 10 mm diameter and 1 mm thickness for dielectric measurements. At last, the green pellets with 1, 3, 5, 10, 15 wt% Zn 2 P 2 O 7 content (marked as sample A, B, C, D, E) were sintered at 1200 \u00b0C for 4 h in air. Pure Ba 0.5 Sr 0.5 TiO 3 pellets were sintered at 1350 \u00b0C for 4 h. Phase structure of the samples was identified by X-ray diffraction (XRD, Bruker D8 Advanced, Germany) with Cu K \u03b1 radiation. The microstructure was characterized by scanning electron microscope (SEM, JSM EMP-800, JEOL, Tokyo, Japan). The samples were polished and sputtered with gold electrodes on both sides for dielectric property measurements. All samples for the DC breakdown measurements were uniformly polished to 0.1 \u00b1 0.01 mm in thickness and tested in silicon oil in order to prevent arcing. Some circular gold electrodes with around 1.2 mm in diameter (area \u2248 1.44 mm 2 , electrode thickness \u2248 50 nm) were sputtered on the top face. The dielectric constant and loss versus temperature was measured using E4980A LCR meter (Agilent, Palo Alto, CA) at 10 kHz and temperature range from \u2212150 \u00b0C to \u2212100 \u00b0C. The dielectric constant dependence on the biasing electric field (0\u201390 kV/cm) was tested in air by a Keithley 2410 (Cleveland, OH) high voltage source and TH2816A LCR (TongHui Electronics, China) analyzer. 3 Results and discussion Fig. 1 (a) shows the XRD patterns of the sintered composite ceramics. Sample A exhibits a single phase of Ba 0.5 Sr 0.5 TiO 3 . But a new phase Ba 3 (PO 4 ) 2 is observed obviously with increasing the content of Zn 2 P 2 O 7 except for BST phase, and the peaks around 32\u00b0 move to large angles (in Fig. 1 (b)). It indicates that the interdiffusion between two phases notably appears during the sintering. It is founded that Zn 2+ (0.90 \u00c5) ions dominantly enter into Ba 2+ (1.610 \u00c5) site in BST lattice because of formation of Ba 3 (PO 4 ) 2 phase. Meanwhile, the new phase may restrain the P 5+ (0.38 \u00c5) ions substitution for Ti 4+ (0.605 \u00c5) at the B site [12] . Such a substitution will lead to the decrease of BST lattice constant. It should display a shift of the diffraction peaks to the large angle in XRD patterns, which is well proved from Fig. 1 (b). The microstructure of sintered sample A, B, C, D, E, and pure BST are presented in Fig. 2 . The grain growth of composite samples is dramatically inhibited compared to that of the pure BST ceramic. The average grain size (\u223c0.5 \u03bcm) of composites is far smaller than that of pure BST ceramic (\u223c5.0 \u03bcm). With increasing of the Zn 2 P 2 O 7 content, the second phase [Ba 3 (PO 4 ) 2 ] gives rise to appearance of liquid-phase at higher temperature (1200 \u00b0C), which acts as compressive phase to restricts the grain growth, and lowers the sintering temperature [13,14] . Dielectric constant and loss dependences on temperature at 10 kHz are shown in Fig. 3 . In comparison with pure BST, the Curie peaks of sample A, B, C, D, and E are obviously suppressed and broadened. The Curie temperature ( T c ) is continuously shifted to the lower temperature from \u221223.5 \u00b0C to \u2212140.1 \u00b0C. The obvious shifts of T c also well adjust the dielectric constants of samples at room temperature from 2020 to 107, and the dielectric loss is also effectively reduced (tg \u03b4 < 0.5%). Generally, the small grain size results in large internal stress, and then causes the shift of T c to low temperature [15] . On the other hand, divalent Zn 2+ ions increasingly enter into divalent Ba 2+ position in BST lattice. The lattice constant of BST is deformed due to crystal cell shrunk, as demonstrated above in Fig. 1 (b). The deformed crystal cells greatly bring the modification of T c [16] . Most importantly, Zn 2 P 2 O 7 addition makes the T c far away from the room temperature and reduces the sensitivity of the dielectric constant on temperature changes. Dielectric constant vs. DC electric field is presented in Fig. 4 , and calculated tunability properties ( T ) are listed in Table 1 . The tg \u03b4 vs. electric field also gives similar curve to tuning one (not shown here). It is found that, all composite samples are subjected to the higher DC electric field (90 kV/cm) without breakdown in air than that of pure Ba 0.5 Sr 0.5 TiO 3 ceramic. With low levels of additives (\u22645 wt%), the tunability is well enhanced and the values keep more than 40%. With increasing the content of Zn 2 P 2 O 7 up to 15 wt%, the Curie temperature ( T c ) moves far away from the room temperature, subsequently the tunability strongly reduced to 8.2%. The average breakdown strengths of all samples, tested in silicon oil, are summarized in Table 1 . The dielectric constant as a function of average breakdown strength is shown in Fig. 5 . The average breakdown strength for each composition is obtained from eight samples. At the DC electric field of 85 kV/cm, pure Ba 0.5 Sr 0.5 TiO 3 ceramic undergoes a breakdown, whereas sample A (186 kV/cm), B (198 kV/cm), C (240 kV/cm), D (297 kV/cm), E (385 kV/cm) can undergo higher electric field than pure BST. Such an obvious improvement in BDS can be well interpreted according to the relation [17] : E bds \u221d G \u2212 a , where E bds is the breakdown strength, G is the grain size, and a is a constant. As the grain size decreases, the BDS clearly increases. Nevertheless, as the content of Zn 2 P 2 O 7 gradually increased from 1 to 15 wt%, it is found that the grain size of BST changes slightly from the SEM images above, but the breakdown strength monotonously increases. More recently, McPherson and co-workers give the universal relationship between dielectric breakdown and dielectric constant as follows [18,19] : E bds \u221d ( \u025b r ) \u22121/2 , wherein E bds and \u025b r are the breakdown strength and the dielectric constant, respectively. The breakdown strength shows an inverse square-root correlation of the dielectric constant. In order to determine whether the BDS and \u025b r of sample A, B, C, D and E follow this trend, the experimental data of \u025b r or ( \u025b r ) \u22121/2 vs. E bds at 20 \u00b0C are fitted using this equation above as the solid lines. As shown in Fig. 5 , all samples have been found to exhibit the expected trend for BDS dependence on dielectric constant. The experimental data can be well fitted, and the correlated coefficient of fitting is 0.989. Consequently, this is sufficiently suggested that so higher BDS is primarily attributed to the reduction of grain size, formation of the second phase, and the substitutions among ions. 4 Conclusions Ba 0.5 Sr 0.5 TiO 3 \u2013Zn 2 P 2 O 7 composite ceramics are fabricated via the solid-state reaction at only 1200 \u00b0C. With the increase of Zn 2 P 2 O 7 content, the dielectric constant of composites is effectively reduced to 107, and the tunability still keeps more than 8%. The tunability of optimum composition with 10 wt% Zn 2 P 2 O 7 is up to 20.5% at 90 kV/cm, together with higher BDS (297 kV/cm), relatively low sintering temperature (1200 \u00b0C) and an appropriate value of dielectric constant (290), which should be a suitable candidate for tunable microwave device applications.

Their dielectric peaks were markedly suppressed, broadened, and shifted to low temperatures with increasing MgO content, indicating that a certain amount of Mg2+ incorporated into BST lattice. The reason why the loss tangent at microwave frequencies increased with the addition of MgO at low concentrations was identified. Raman spectra analysis clearly indicated that the incorporation of Mg2+ degraded quality factor (Q value) of BST, which was ascribed to the deterioration of B-site ordering of the ABO 3 perovskite structure. It was found that Q value was strongly correlated with the Raman peak width of A1 (TO) stretch modes in perovskite materials. Also oxygen octahedron played an important role in determining the material's microwave performance. The decrease in loss tangent at microwave frequencies of the samples with high contents of MgO was resulted from the \"composite\" effect of the dielectric component. \u00a9 2011 The American Ceramic Society.",

Further study shows that with the increasing of TiO2 content the dielectric constant increases first then decreases afterwards and the temperature coefficient of dielectric constant decreases from positive to negative.

Results showed that the K yNN substitution into BNKT20 induces a phase transition from coexistence of ferroelectric tetragonal and rhombohedral to a relaxor pseudocubic with a significant disruption of the long-range ferroelectric order, and correspondingly adjusts the ferroelectric-relaxor transition point T F-R to room temperature. Accordingly, a large electric-field-induced strain of 0.33%-0.46% (Smax/Emax = 413-575 pm/V), which is derived from a reversible field-induced ergodic relaxor to ferroelectric phase transformation, was obtained in KyNN-modified compositions near the phase boundary. Moreover, a relationship between the position of the ferroelectric-relaxor phase boundary and the tolerance factor t of the end member KyNN was found in BNKT20-xKyNN system, which is expected to provide a guideline for searching the new ferroelectric-relaxor phase boundary where the strain response is consistently derivable in (Bi 0.5Na0.5)TiO3-based materials. ? 2014 AIP Publishing LLC.",

However, the extremely low piezoelectric properties hinder its application. A combination method with element doping and texturing was used to improve the electric properties of CBN ceramic. First of all, the Mn element was chosen to be doped to improve the piezoelectric and resistance properties of CBN ceramic. Then, an optimal composition was subsequently textured by templated grain growth (TGG) method to further improve the piezoelectric properties. The piezoelectric properties, Curie temperature (Tc), and resistivity of textured Ca0.95Mn0.05Bi 2Nb2O9 ceramics (d 33 = 21, k p = 10.9 %, Tc = 942 C, \u03c1 = 2.1 \u00d7 10 5\u03a9\u00b7cm at 600 C) were improved obviously compared to pure random CBN ceramics (d 33 = 6, k p = 4.6 %, Tc = 930 C, \u03c1 = 0.6 \u00d7 105\u03a9\u00b7cm at 600 C). Furthermore, it has excellent resistance to thermal depoling and keep about 5.7 % kp until the temperature up to 600 C. This combination method makes the textured Ca 0.95Mn0.05Bi2Nb2O9 ceramics to be a promising candidate for high-temperature piezoelectric applications. \u00a9 2012 Springer Science+Business Media New York.",

Here, ultrahigh piezoelectric properties with piezoelectric coefficients (d \u2248700 pC N , d * \u2248980 pm V ) and planar electromechanical coupling factor (k \u224876%) are achieved in highly textured (K,Na)NbO (KNN)-based ceramics. The excellent piezoelectric properties can be explained by the strong anisotropic feature, optimized engineered domain configuration in the textured ceramics, and facilitated polarization rotation induced by the intermediate phase. In addition, the nanodomain structures with decreased domain wall energy and increased domain wall mobility also contribute to the ultrahigh piezoelectric properties. This work not only demonstrates the tremendous potential of KNN-based ceramics to replace lead-based piezoelectrics but also provides a good strategy to design high-performance piezoelectrics by controlling appropriate phase and crystallographic orientation.",

Textured 92BNT-6BT-2KNN with a Lotgering factor of 67% was obtained by templated grain growth method using plate-like (Bi 0.5Na 0.5)TiO 3 (BNT) particles as templates. The influence of sintering process on Lotgering factor and strain was investigated. It was found that the Lotgering factor increased as sintering temperature increase and then decreased with further temperature increase. The changing tendency of polar and unipolar strain did not keep the same accordance with that of Lotgering factor. The maximum of Lotgering factor (79%) and polar strain (0.36%) was obtained when the sintering temperature was 1240\u00b0C and 1220\u00b0C, respectively, due to the decrease of density when high sintering temperature was employed. Also it was found that the lotgering factor and polar strain reached its highest values when the soaking time was 4h. All these proved that the density and grain orientation codetermined the strain of 92BNT-6BT-2KNN ceramics. \u00a9 (2012) Trans Tech Publications.",

Curie points of the copolymers are shifted progressively toward higher temperature with frequency increasing, and they decrease largely with irradiation dose increasing. Hysteresis loops of P(VDF/TrFE) were performed under different electric fields and electron-irradiated. The hysteresis loop had a middle-shrunk shape under low field. It was changed gradually into a shape of normal ferroelectric with increasing of the measuring electric field. The coercive field and remanent polarization of samples are gradually decreasing with the increasing irradiation dose, and the hysteresis loops become slimmer. The mechanisms of above phenomena are discussed in this paper.",

The phase structure was investigated by X-ray diffraction and results show that a single perovskite phase was obtained in all of these samples, suggesting that the added BMT diffused into BCZT to form a solid solution. Dense ceramics with relative densities >95% were obtained, and a small amount of BMT (\u226450 mol%) acted as grain growth promoter, had an evident effect on grain size growth. Further increase of the BMT content inhibited the grain growth of BCZT samples. Temperature dependence of the dielectric properties showed that all the BCZT-BMT solid solution ceramics exhibited relaxor-like characteristics. With increasing BMT content, the Curie temperature was first increased and then decreased, giving a maximum value of 218 \u00b0C for the 0.4BCZT-0.6BMT composition. Furthermore, stable dielectric constants and low losses were obtained with 0.5\u2264x\u22640.7 in the wide temperature range, indicating that the system possess potential for high-temperature application. \u00a9 2012 Elsevier Ltd and Techna Group S.r.l.",

Keywords NBT-BT Thin film Buffer layer Ferroelectric properties 1 Introduction Lead-based ferroelectric materials represented by PbTiO 3 and Pb(Zr, Ti)O 3 are widely used due to their excellent ferroelectric and piezoelectric properties. However, lead toxicity is a tremendous disadvantage to the environment. Inevitably, developing lead-free materials is of great importance. Sodium bismuth titanate Na 0.5 Bi 0.5 TiO 3 (NBT) is considered to be one of the promising materials since it was discovered by Smolenski et al. [1] . Bulk ceramics of NBT have shown strong ferroelectricity at room temperature (remnant polarization P r = 38 \u03bcC/cm 2 and coercive field E c = 73 kV/cm) with a relative high Curie temperature of 320 \u00b0C. NBT-based bulk ceramics modified with BaTiO 3 (BT) show improved properties due to the existence of rhombohedral\u2013tetragonal morphotropic phase boundary (MPB) [2,3] . The piezoelectric constant d 33 of the NBT-BT ceramics with the MPB composition can reach up to 125 pC/N [4] , and the (1 0 0)-oriented crystals grown by spontaneous nucleation method showed a piezoelectric constant of d 33 = 450 pC/N and electric field induced strain up to 0.25% [5] . Also, for MPB composition, some researchers got bulk ceramics with pyroelectric coefficient Pi = 3.9 \u00d7 10 \u22124 cm \u22122 K \u22121 [6] , which possibly resulted from the large spontaneous and remnant polarization ( P r = 40 \u03bcC/cm 2 ) and lower depolarization temperature ( T d = 100 \u00b0C) [4] . However, NBT-BT in the form of thin films has rarely been studied because the existence of precipitation when adding BT to NBT. Recently, we use ammonia solution to stabilize the solution. Meanwhile, buffer layers are widely used to improve the properties of the thin films, such as LaNiO 3 and NaNbO 3 [7\u20139] . LaNiO 3 (LNO) has a pseudo cubic perovskite structure ( a = 3.84 \u00c5), which is not only a good candidate for the electrode material due to its good metallic conductivity, but also a promising buffer layer material for oriented growth. 2 Experimental Two solutions were fabricated with nominal compositions of Na 0.5 Bi 0.5 TiO 3 (NBT) and BaTiO 3 (BT), respectively. The NBT sol was synthesized first. Sodium acetate, CH 3 COONa\u00b73H 2 O, bismuth nitrate, Bi(NO 3 ) 3 \u00b75H 2 O, were mixed and stirred in acetic acid at 70 \u00b0C for 120 min, which was denoted as sol 1. On the other hand, acetylacetone (CH 3 COCH 2 COCH 3 ) was mixed with 2-methoxyethanol, stirred for 30 min, and we added titanium tetra-n-butyl into the mixture. The mixture was stirred constantly until a transparent solution was obtained. We denoted this sol as sol 2. Sol 1 and sol 2 were mixed and control the concentration to 0.3 M by adding acetic acid. After stirring for 60 min, NBT sol was prepared. Barium acetate, Ba(CH 3 COO) 2 , was dissolved in acetic acid at 70 \u00b0C for 30 min, which was denoted as sol 3. Meanwhile, we made sol 4 using the same method of sol 2. Thereafter, sol 3 and sol 4 were mixed and stirred for 60 min. We control the concentration to 0.3 M by adding acid. Proper amounts of NBT and BT were mixed and we added ammonia water until it became transparent. After stirring for 60 min, NBT-BT sol was prepared, and the concentration will be adjusted to 0.3 M by adding acid. The flow chart of the synthesis process of the precursor solution is shown in Fig. 1 . There are two kinds of substrates used in this study, Pt/Ti/SiO 2 /Si (1 1 1) and LaNiO 3 /Pt/Ti/SiO 2 /Si (1 1 1) substrates. The LNO layer was prepared by magnetron sputtering on Pt/Ti/SiO 2 /Si (1 1 1) and the substrate temperature was kept at 300 \u00b0C. The LNO film exhibited a single perovskite phase with strong (1 0 0) orientation. The NBT-BT solutions were deposited on the two substrates by spin-coating at 3000 rpm for 20 s, respectively. After spin-coating, the gel layers were dried at 400 \u00b0C for 10 min. The spin-coating and heat-treatment process were repeated several times to obtain the desired thickness. Finally, the films were annealed at 700 \u00b0C for 30 min. The crystalline phase of the films was determined by X-ray diffraction (BRUKER D8, Germany). The surface morphology was identified by FESEM (FEI Quanta 200 FEG). For electrical measurements of a metal/insulator/metal (MIM) structure, gold electrode pads of 500 \u03bcm in diameter were prepared through a shadow mask by DC-sputtering. The capacitance\u2013voltage and capacitance\u2013frequency characteristics were measured using an Agilent 4980A LCR meter. The leakage current\u2013voltage characteristics were measured using a Keithley 6517A. The hysteresis loops were acquired by a ferroelectric test system (Radiant Precision Premier \u041f). 3 Results and discussion Fig. 2 shows the XRD patterns of the NBT-BT thin films deposited on Pt/Ti/SiO 2 /Si (1 1 1) and LNO/Pt/Ti/SiO 2 /Si (1 1 1) substrates. The XRD patterns indicated that the thin film deposited on Pt/Ti/SiO 2 /Si substrates is polycrystalline structure. But, films deposited on LNO/Pt/Ti/SiO 2 /Si substrates showed a highly preferred orientation of (1 0 0). The degree of grain orientation can be calculated by Lotgering factor f , which is defined as [10] (1) f = p \u2212 p 0 1 \u2212 p 0 where (2) p = \u2211 i I ( h \u2009 0 \u2009 0 ) \u2211 i I ( h \u2009 k \u2009 l ) (3) p 0 = \u2211 i I ( h \u2009 0 \u2009 0 ) \u2211 i I ( h \u2009 k \u2009 l ) and \u2211 i I ( h 0 0) is the sum of the ( h 0 0) peak intensities for the sample, \u2211 i I ( h k l ) is the sum of all peak intensities in the sample diffraction pattern, while the data for p 0 are the parameters provided by the standard PDF cards. The orientation degree of NBT-BT thin film deposited on LNO/Pt/Ti/SiO 2 /Si substrates is 81%, whereas the value for the other is only 40%. Based on the XRD results, we can contribute the highly (1 0 0) orientation to the good lattice match between NBT-BT and LNO buffer layer. Only series of NBT-BT peaks were observed, suggesting that there is no second phase in these films. The peaks are sharp, indicating that the thin films are well crystallized. Fig. 3 (a) indicates that the thin film deposited on LNO/Pt/Ti/SiO 2 /Si substrates is crack-free, uniform and in a dense form. While the thin film deposited on Pt/Ti/SiO 2 /Si substrates is also crack-free, but it has some pores, as shown in Fig. 3 (b), which may affect the properties of the thin film. The dielectric constant and loss tan \u03b4 were measured as function of voltage and frequency at room temperature, respectively, as shown in Figs. 4 and 5 . The electric field is applied as follows: 300 \u2192 0 \u2192 \u2212300 \u2192 0 \u2192 300 kV/cm. The C \u2013 V curve shows strong non-linear dielectric behavior. As shown in Fig. 4 , the dielectric constant of NBT-BT thin film deposited on Pt/Ti/SiO 2 /Si substrates was higher, and the dielectric loss was lower as well. The largest dielectric constant ( \u025b r ) value is obtained by applying the electric field in a direction vertical to the polarization direction and the smallest \u025b r value is obtained when the direction of the applied electric field is parallel to the polarization direction [11] . Considering the preferred orientation of NBT-BT thin film deposited on LNO/Pt/Ti/SiO 2 /Si substrates is (1 0 0), we got the smallest \u025b r , which is smaller than the film without any preferred orientation. Meanwhile, there is a slight asymmetry observed in the C \u2013 V curves, suggesting that the thin films contain movable ions or charges accumulated at the interface between the film and the electrodes. The dielectric constant and loss are about 630 and 0.03 at 10 kHz at room temperature for the thin film deposited on Pt/Ti/SiO 2 /Si substrates, while the values are 450 and 0.06 for the other film. In addition to the dielectric properties, the leakage current characteristics are also very important. In this study, the current\u2013voltage measurements were conducted in metal\u2013insulator\u2013metal (MIM) configuration. As shown in Fig. 6 , the leakage current density is about 6 \u00d7 10 \u22123 A/cm 2 at 250 kV/cm and an abrupt increasing trend is observed at higher electric field for the films deposited on Pt/Ti/SiO 2 /Si substrates. Under the electric field of 400 kV/cm, NBT-BT film deposited on LNO/Pt/Ti/SiO 2 /Si substrates showed a much lower leakage current, nearly 1/5 of the film deposited on Pt/Ti/SiO 2 /Si substrates. From Fig. 3 (b), we can see some pores, and the pores may lead to the high leakage current under high electric field. The NBT-BT film deposited on Pt/Ti/SiO 2 /Si substrates may have more oxygen vacancies trapped at the grain boundaries that can pin domains and result in the high leakage current as well as the low dielectric loss [12,13] . Fig. 7 shows the hysteresis loops of the thin films. The hysteresis loops at an applied electric field of 300 kV/cm and 10 kHz were acquired for NBT-BT films deposited on Pt/Ti/SiO 2 /Si substrates (saturation polarization P s \u223c 18 \u03bcC/cm 2 , remnant polarization 2 P r \u223c 7.5 \u03bcC/cm 2 and coercive field 2 E c \u223c 70 kV/cm). Meanwhile, the hysteresis loops for NBT-BT films deposited on LNO/Pt/Ti/SiO 2 /Si substrates were also acquired at the same condition. There was an increase of the coercive field (2 E c \u223c 100 kV/cm). But the saturation polarization is bigger ( P s \u223c 21 \u03bcC/cm 2 ) and the remnant polarization was 40% larger (2 P r \u223c 11 \u03bcC/cm 2 ), which may derive from the preferred orientation and better crystallinity of the thin film as shown in Figs. 2 and 3 [14] . 4 Conclusions (Na 0.5 Bi 0.5 ) 0.94 Ba 0.06 TiO 3 thin films were deposited on Pt/Ti/SiO 2 /Si (1 1 1) and LNO/Pt/Ti/SiO 2 /Si (1 1 1) substrates by a sol\u2013gel process. The X-ray diffraction pattern indicated that the NBT-BT thin film deposited on Pt/Ti/SiO 2 /Si (1 1 1) substrates is polycrystalline structure without any preferred orientation. But the NBT-BT thin film deposited on LNO/Pt/Ti/SiO 2 /Si substrates shows highly (1 0 0) orientation. NBT-BT thin film deposited on LNO/Pt/Ti/SiO 2 /Si substrates possessed a much lower leakage current, nearly 1/5 of the NBT-BT film deposited on Pt/Ti/SiO 2 /Si substrates under 400 kV/cm. There was an increase of the coercive field for the NBT-BT films deposited on LNO/Pt/Ti/SiO 2 /Si substrates. But P s and 2 P r is about 21 \u03bcC/cm 2 and 11 \u03bcC/cm 2 , and are much bigger than that of thin film deposited on Pt/Ti/SiO 2 /Si.

Keywords A. Ceramics A. Composites B. X-ray diffraction D. Dielectric properties 1 Introduction Barium strontium titanate (Ba 1\u2212 x Sr x TiO 3 or BST) ferroelectric materials have attracted significant interests due to their electrically tunable dielectric properties for potential application in tunable microwave devices, such as oscillators, tunable mixers, delay lines, steerable antennas, parametric amplifiers, capacitors, varactors, resonators, voltage-controlled oscillators, tunable filters and phase shifters [1\u20138] . All these applications require materials with low dielectric loss (tan \u03b4 ), high tunability ( T ) and appropriate value of dielectric permittivity (<500) [9] . BST is one of the most promising candidates owing to its high tunability and low loss [10,11] . However, pure BST has relatively high dielectric permittivity ( \u025b ) and thus is not suitable for practical tunable microwave device applications. It has been shown that adding low dielectric permittivity non-ferroelectric phase (such as MgO, Al 2 O 3 , Mg 2 SiO 4 , and Mg 2 TiO 4 ) [11\u201319] into ferroelectric material is an effective method to reduce its dielectric permittivity and loss while maintaining acceptable dielectric tunabilities. In most cases, low dielectric permittivity is readily achievable, but microwave loss is usually increased while tunability is decreased. Addition of MgO was found to suppress dielectric permittivity, losses and tunability of BST ceramics. Wu et al. [17] reported that 1 wt% Al 2 O 3 -doped Ba 0.6 Sr 0.4 TiO 3 ceramics had very low loss and relatively high tunability, but their dielectric permittivity was still higher than the requirement of real applications. BST\u2013Mg 2 SiO 4 composite ceramics displayed relatively high tunability, adjustable dielectric permittivity and relatively low dielectric loss. However, these properties were still not satisfactory for microwave applications [18] . Similarly, Ba 1\u2212 x Sr x TiO 3 \u2013Mg 2 TiO 4 based composite ceramics also had similar problems for microwave applications due to their relatively high loss tangent at microwave frequencies. Introduction of MgO into BST\u2013Mg 2 SiO 4 binary composites resulted in BST\u2013Mg 2 SiO 4 \u2013MgO ternary composites, which had readily adjustable dielectric permittivity without decreasing their tunability but increasing their dielectric loss at microwave frequencies [13,19] . The reduced dielectric permittivities of BST as a result of the addition of low dielectric permittivity non-ferroelectric phases were at the expense of increase in dielectric losses as well as decrease in dielectric tunability. In this study, we tried to further improve microwave dielectric properties of BST-based composite ceramics. BaWO 4 microwave dielectric material [20] with low dielectric permittivity ( \u025b = 8.27) and high quality factor ( Q \u00d7 f = 30,229) was used to form composites with Ba 0.4 Sr 0.6 TiO 3 ferroelectric ceramics. The effect of BaWO 4 on the dielectric properties of BST40 ceramics was systematically investigated to evaluate their suitability for microwave device applications. This study was aimed at finding a composite BW\u2013BST system that has high Q value, high dielectric tunability and appropriate level of dielectric permittivity. At the same time, mechanisms that govern dielectric properties of the BW\u2013BST composite ceramics will be discussed in detail. 2 Experimental x BaWO 4 (BW)\u2013(1 \u2212 x )Ba 0.4 Sr 0.6 TiO 3 (BST) ( x = 15, 30, 45, 60 wt%) composite ceramics were prepared by the conventional solid-state reaction route. High purity BaCO 3 (99.8%), SrCO 3 (99.0%), TiO 2 (99.9%) and WO 3 (99.8%) were used as the starting materials. BST and BaWO 4 powers were synthesized at 1200 \u00b0C and 1100 \u00b0C, respectively. Then, the two powders were mixed according to the stoichiometric ratios of x BW\u2013(1 \u2212 x )BST and ball-milled with zirconia media in ethanol for 24 h. The dried powders, mixed with 8 wt% polyvinyl alcohol (PVA), were pressed into pellets. Samples for low frequency dielectric measurement are 10 mm in diameter and 1 mm in thickness, while those for microwave frequency measurements have dimensions of 10/5 mm, 12/6 mm, 15/7 mm and 17/8 mm in diameter/thickness, respectively. The green pellets were kept at 550 \u00b0C for 6 h in air to remove the solvent and the binder and then sintered at 1320\u20131340 \u00b0C in air for 4 h. Phase identification of the sintered ceramics was conducted by using X-ray diffraction (XRD, Bruker D8 Advanced, Germany) with Cu K\u03b1 radiation. Back electron image (BEI, JSM EMP-800) was used to characterize microstructures of the samples. Temperature dependent dielectric permittivity ( \u025b ) and loss tangent (tan \u03b4 ) of the ceramics were measured over 150\u2013400 K at 10 kHz by using a HP4284A precision LCR meter (Agilent, Palo Alto, CA). Room temperature dielectric permittivity versus DC bias voltage was measured at 10 kHz by using a Keithley model 2410 (Cleveland, OH) high voltage source coupled with TH2816A LCR meter (Changzhou, China). Microwave dielectric permittivity and loss of the samples were measured by using the resonance method [21] with a vector network analyzer (Agilent E5071C). 3 Results and discussion BEI micrographs of natural surfaces of the BW\u2013BST40 ceramics are shown in Fig. 1 . It is demonstrated that BW\u2013BST ceramics have all a dense and uniform microstructure. The two component phases can be observed distinctively in the composite ceramics. Energy dispersive spectroscopy (EDS) result of the sample with x = 60 wt% is also shown in Fig. 1 . The dark phase consists of primarily Ba, Sr, Ti and O, while the light phase consists of primarily Ba, W, O and small amount of Sr. It suggests that the dark grains are BST (marked as \u201c1\u201d) while the light grains are BW (marked as \u201c2\u201d). This EDS result indicated that inter-diffusion between BST and BW occurred during the sintering process. BST grains of the composite ceramics are smaller than those of pure BST40 (not shown here). The grain sizes of pure BST40 are more than 15 \u03bcm, however, the grain size in BST\u2013BW composite is about 1 \u03bcm. This indicates that the addition of BW reduced the grain sizes of BST. The grain size of the BW phase increased with increasing content of BW and its distribution became more homogeneous, but grain size of the BST phase kept almost unchanged. XRD patterns of the BW\u2013BST composite ceramics are shown in Fig. 2 . All samples can be indexed as two phases of cubic perovskite BST and wolframite BaWO 4 . The absence of secondary crystalline phases implies no obvious chemical reaction between BST and BW phase. The (2 1 1) and (2 2 0) peaks of pure BST and the BW\u2013BST are enlarged in order to observe the shift of diffraction peaks as shown in Fig. 2 (b). Compared with pure BST, both (2 1 1) and (2 2 0) peaks shift toward lower angle with increasing BW content, indicating a lattice expansion of the BST. The variation of the cell parameter obtained from XRD analysis by Jade 5.0 is plotted in Fig. 3 . This lattice expansion can be attributed to an increase of Ba/Sr ratio in the BST phase due to the inter-diffusion, as demonstrated by the above EDS result, because the radius of Sr 2+ ion (coordination number N = 12, ionic radius = 1.44 \u00c5) is smaller than that of Ba 2+ ion (coordination number N = 12, ionic radius = 1.61 \u00c5) [22] . Fig. 3 also shows that the lattice expansion tended to saturate at x = 45 wt%, which means that there has a limit in ion s inter-diffusion at this composition. In our previous work, we got a relationship between the value of Ba 1\u2212 x Sr x TiO 3 and T C , as shown in Fig. 4 . According to the fitting formula we can get a rough Ba/Sr ratio of the samples as follows: 0.422/0.578, 0.433/0.567, 0.441/0.549, and 0.473/0.527. Temperature dependences of dielectric permittivity of the BW\u2013BST composite ceramics are shown in Fig. 5 . Microwave dielectric properties of all samples measured at room temperature are listed in Table 1 . Dielectric peaks of the composite ceramics were broadened and suppressed with increasing content of BW. Meanwhile, Curie temperature ( T C ) of the composites increased gradually. The decrease in dielectric permittivity can be readily attributed to a dilution effect caused by BW and the diffuse phase transition of the samples [10] . For example, room temperature dielectric permittivity (10 kHz) is decreased from 1098 for pure BST to 212 for the sample with x = 0.6. On the other hands, the increase in fraction of grain boundary which is caused by the decrease in BST grain size could be an additional contributor to the reduction in dielectric permittivity with increasing content of BW. Temperature dependent dielectric losses of all samples are also presented in Fig. 5 . The composite ceramics have significantly low dielectric losses as a result of the addition of the low loss non-ferroelectric BW [23] . Dielectric losses of all samples increase with increasing temperature above 250 K, which may be attributed to the increase of conduction loss at high temperatures [24] . Furthermore, T C increases with increasing content of BW from 15 to 60 wt%, which should be attributed to the increase of Ba/Sr ratio originating from the inter-diffusion as discussed above [25] . Fig. 6 shows DC field dependences of dielectric permittivity of all samples measured at 10 kHz and 20 \u00b0C. Loss tangents of the samples were also measured at 10 kHz and room temperature (not shown here). The BW\u2013BST composite ceramics have higher tunability than pure BST, which could be related to their relatively high Ba/Sr ratio. Tunabilities of the samples decrease from 23.2 to 16.0% (at 30 kV) with increasing content of BW from x = 15 wt% to x = 60 wt%, which is attributed to the increase of the non-ferroelectric content. However, our BW\u2013BST composite ceramics still have sufficiently high tunabilities. The inter-diffusion between Ba ions (in BW) and Sr ions (in BST) drove T C upwards and thus led to high tunability at room temperature. Their high tunabilities might also be related to their homogeneous microstructures [26,27] . It is well known that tunability in a ferroelectric state is larger than that in a paraelectric state and the maximum tunability appears at the vicinity of phase transition temperature [28,29] . Specifically, the sample with x = 60 wt% has a dielectric permittivity of 249 and yet a tunability of 16% (at 30 kV/cm and 20 \u00b0C). This result is very encouraging as compared with those of other BST-based composites [30] . For instance, the tunability of MgO\u2013BST decreased abruptly with increasing content of MgO. The high tunability and low dielectric permittivity make our BW\u2013BST composite ceramics attractive materials for tunable microwave device applications. It is well known that the effect on dielectric permittivity by DC field of BST in paraelectric state originates from the anharmonic interaction of Ti 4+ ions. An anharmonic interaction is attributed to the crystal field exerted in a material. An anharmonic potential of Ti 4+ is generated in a material with perovskite structure due to the symmetry group. The anharmonic interaction can be visualized as an inelastic feature of the covalent bond constructed by Ti 4+ and O 2\u2212 . Therefore, the magnitude of the dipole moment will be suppressed at DC biasing [31] , which causes the reduction of dielectric permittivity. As is well known, dielectric tunability of a given material is correlative with strength of the external field. Generally, the higher the external field is applied, the higher the tunability will be. As shown in Fig. 6 , dielectric permittivity of the BST\u2013BW composite ceramics decrease with increasing external field, which is attributed to the anharmonic interaction of Ti 4+ ions. It can be explained by the phenomenological theory of Devonshire [32,33] . Johnson proposed an expression for permittivity under DC field as: (1) \u03b5 r ( a p p ) \u03b5 r ( 0 ) = 1 [ 1 + \u03b1 \u03b5 r ( 0 ) 3 E 2 ] 1 / 3 where \u025b r (0) and \u025b r ( app ) are the dielectric permittivity at zero DC field and an applied field, respectively, and \u03b1 is the anharmonic coefficient. \u03b1 is determined by both the anharmonic interaction and the dielectric permittivity of the sample. Larger dielectric permittivity and stronger anharmonic interaction would yield a higher value of field coefficient. In this case, DC field will be more effective in reducing the dielectric permittivity. Eq. (1) can be simplified by using Eq. (2) : (2) y = 1 + b x where y = ( \u025b r (0) / \u025b r (app) ) 3 , x = E 2 and b = \u03b1 \u03b5 0 3 . It was reported that all experimental curves in the intermediate range of electric fields can be well fitted by the bias equation [34] . Fig. 7 shows linear fittings of experimental data of the BW\u2013BST composite ceramics. The samples with x = 15 wt% and x = 30 wt% have two linear regions, with a large slope over 0\u201316 kV/cm \u22121 and small slope over 16\u201330 kV/cm \u22121 . It means that the dielectric responses of the composite materials at external DC fields cannot be solely described by the phenomenological theory at different effective Ba concentrations in BST, which result in the difference in T C . This deviation could have other extrinsic contributions, such as polar clusters, microcluster boundaries, defects, and space charge polarization [35] . At a strong DC field, polar micro-domains in nanoscale polar micro-regions would grow up, resulting in a congelation and consolidation of polar micro-regions and a reduction in the number of ferroelectric\u2013paraelectric domain walls. The contribution of reversible polarizations is reduced, which leads to a reduction in dielectric permittivity. The congelation and consolidation of polar micro-regions tend to saturate with further increasing DC field, whose contribution to tunability is dying down. For the samples with x = 0.45 and 0.60, since T C is getting closer to measuring temperature, polar micro-region contribution to the change of dielectric permittivity is increasing, which is the reason why the slope dose not depress with increasing DC field. In Fig. 7 , the decline slope means a decrease in tunability with increasing content of BW, which can be attributed to the increase of the non-ferroelectric content. Shown in Fig. 8 , we measured tunabilities at different DC biases (7 points). An increase in tenability with DC bias can also be observed, which is consistent with the conclusion drawn above. The change in slopes of the samples with x = 15 and x = 30 means a reduction in change rate of their dielectric permittivity as a function of DC electric field. Slopes of the samples with x = 45 and x = 60 are constant, indicating a steady change rate of decrease in their dielectric permittivity. Microwave dielectric properties of all samples measured at room temperature are listed in Table 1 . Dielectric permittivities of the composite ceramics are evidently decreased at microwave frequencies as compared with those at low frequencies (below 1 MHz). Q value decreases with the content of BW at first, reaches a minimum vale at x = 15 wt% and then increases with increasing content of BW. This variation can be understood by taking into account both intrinsic and extrinsic dielectric responses [36,37] . Extrinsic loss contributors include charged defect, residual ferroelectric polarization, and local polar-regions. The high microwave losses of the samples with low contents of BW could be attributed to the main extrinsic loss due to their poor microstructure homogeneities [37] . At high concentrations of BW, the high Q value of BW became dominate factor. On the other hand, good compositional homogeneity of the samples with high contents of BW also favored to increase their Q factors [38] . It is worth mentioning that the sample with x = 0.6 has an acceptable level of Q value of 231 at \u223c2.700 GHz, a high tunability (\u223c29.5% at 60 kV/cm) and an appropriate value of dielectric permittivity (\u223c192 at zero biasing), which makes this composite a promising candidate for applications in tunable microwave devices. 4 Conclusions x BaWO 4 \u2013(1 \u2212 x )Ba 0.4 Sr 0.6 TiO 3 composite ceramics were fabricated and characterized. All samples consisted of Ba 0.4 Sr 0.6 TiO 3 and BaWO 4 phases. T C peaks of the composite ceramics were suppressed, broadened and shifted to higher temperatures with increasing content of BW. Dielectric tunability properties of the BW\u2013BST composites at a DC bias field near the phase transition temperature were interpreted using Johnson's phenomenological equation. The sample with x = 0.60 had a dielectric permittivity of 192, a tunability of 29.5% and a Q factor of 231 (at 2.700 GHz). The low dielectric permittivity composite ceramics with high tunability and good microwave properties are promising candidates in tunable device applications.

The dielectric constant is 247-83 in the frequency range of 1 kHz-1 MHz. The corresponding dielectric loss is ~10-2. The capacitance-voltage curve shows strong non-linear dielectric behavior leading to a high tunability, up to ~30% at 1 kHz. The remanent polarization and coercive field at room temperature are measured to be ~1.5 \u03bcC/cm2 and ~90 kV/cm. The infrared optical properties of the thin films are investigated using an infrared spectroscopic ellipsometry in the wave number range of 800-4,000 cm-1.

The phase transition behavior and electrical properties of the ceramics were studied. Results show that (Ba 0.85Ca0.15)(Zr0.1Ti0.9)O 3 diffuses into (K0.48Na0.52)NbO3 to form a new solid solution, and induces a phase structure transition from orthorhombic to tetragonal phase with the increase of x. At 0.04\u2264x\u22640.06, coexistence of the orthorhombic and tetragonal phases is observed, and enhanced piezoelectric properties are achieved in this region due to the polymorphic phase transition near room temperature. The doping of MnO2 effectively promotes the densification of the ceramics and further enhances the piezoelectric and dielectric properties at room temperature. The ceramics with 0.04\u2264x\u22640.06 and 1.0 mol% MnO2 possess excellent electrical properties: d33=200-262 pm/V, d33=153-182 pC/N, \u03b5r=763-976, tan \u03b4=0.054-0.060, Tc=268-312 \u00b0C. Moreover, samples with single tetragonal phase at x=0.07 have a good temperature stability in the temperature range of 25-150 \u00b0C due to the shift of the orthorhombic to tetragonal polymorphic phase transition below room temperature. \u00a9 2012 Elsevier Ltd and Techna Group S.r.l.",

The phase composition and microstructure of these powders were analyzed by X-ray diffraction and scanning electron microscopy. The mechanism of the tabular BaTiO3 growth was studied preliminarily. The results indicate that the two-steps molten salt process parameters and the mole ratio of raw materials greatly affect the microstructure of the intermediate Bi4Ti3O12. It was found that the tabular size increases with the increasing of the reaction temperature below 1000\u00b0C, and with the increasing of the amount of Bi2O3. In addition to the microstructure of the intermediate Bi4Ti3O12, the reaction temperature and the mole ratio of raw materials also have an obviously effect on the microstructure and size of the BaTiO3.

The grain orientation degree decreased with increasing Mn 2+ and reduced to 50% for the thick film with 5 mol% Mn 2+. The addition of Mn 2+ improved the microstructure of the thick film.

By adding 0.05 wt.% CuO together with 0.05 wt.% V 2 O 5 into \u03b2-BZT ceramics, microwave dielectric properties were \u03b5 =\u223c63 and Qf =\u223c6787 at \u223c5.35 GHz with \u03b1 \u03b5 =\u223c73 ppm/\u00b0C at 1 MHz at a sintering temperature of 930 \u00b0C which retained a relative high microwave dielectric properties compared with the undoped \u03b2-BZT sintered at 1030 \u00b0C. Keywords A. Sintering Bismuth-based ceramics CuO/V 2 O 5 Microwave dielectric properties 1 Introduction The development of multilayer devices for microwave applications has received wide attraction since multilayer devices have unique characteristics of small size and high volume efficiency. It is well known that high-frequency performance of co-fired multilayer devices is generally dominated by the metal conductivity [1] . In order to reduce the dielectric loss, the electrodes with higher conductivity such as silver have to be used in the co-firing process. At the same time, low sintering temperature and chemical compatibility with the electrode material are needed for host dielectric material during co-firing. Studies of the dielectric properties of bismuth-based pyrochlores have demonstrated that they may be suited toward applications as co-fired dielectric component [2,3,6] . Bi 2 O 3 \u2013ZnO\u2013Ta 2 O 5 (BZT) series ceramics were required to be sintered above 1000 \u00b0C to reach high density. For co-firing process, this sintering temperature is too high to use pure silver electrode. To reduce the sintering temperature of dielectric materials, liquid phase sintering aid was effectively used [4,5] : glass or other low-melting point materials were mixed with dielectric materials. However, the microwave dielectric properties of dielectric materials were also deeply affected by the liquid sintering temperature due to the development of microstructure at low sintering temperature or the reaction between host material and additives. Hiroshi Kagata et al. [6] reported that with the addition of CuO and V 2 O 5 into BiNbO 4 , this ceramics could be sintered at a temperature as low as 875 \u00b0C and their properties were improved too. In this paper, CuO/V 2 O 5 were chosen as a liquid sintering aid to study the role in densification and microwave dielectric properties of Bi 2 Zn 2/3 Ta 4/3 O 7 (\u03b2-BZT) ceramics. The crystalline phases, the microstructures and the microwave dielectric properties of CuO/V 2 O 5 doped \u03b2-BZT ceramics were presented. 2 Experimental procedures High purity Bi 2 O 3 , ZnO and Ta 2 O 5 (purity >99%) were used as starting materials to synthesize \u03b2-BZT ceramics. The compositions were prepared by conventional powder processing technique. Stoichiometric mixtures were mixed and ball-milled for 20 h with deionized water using zirconia media in polyethylene containers. The mixed slurry was dried in an oven at 120 \u00b0C for 15 h. The dried powders were calcined in air at 800 \u00b0C for 4 h in covered alumina crucibles to form \u03b2-BZT crystalline structure as confirmed with X-ray diffractometer. Followed, the \u03b2-BZT powder and a certain content of CuO/V 2 O 5 powder were mixed, dried and calcined. After granulated, the resultant powders were uniaxially die-pressed into discs having a diameter of 12 mm and thickness of 2 or 6 mm under a pressure of 8 MPa/cm 2 . All 6 mm height specimens used for microwave measurements were experienced cold isostatic pressing process. The samples were sintered at various temperatures from 890 to 970 \u00b0C for 4 h with a ramping rate of 3 \u00b0C/min. The electrodes of samples were coated with silver paste and fired. The bulk density of as-sintered pellets was measured using the METTLER TOLEDO AG285 balance and the density determination kit for balance (Archimedes method). The structure of sintered pellets was performed by Bruker D8 X-ray diffractometer (XRD). The surface was observed by SEM (JSM-5510LV). The temperature dependence of the dielectric constant and dissipation factor was measured using an automated measurement system consisting a computer, a HP 4284A LCR meter and a temperature chamber. The temperature range was between \u221260 and 160 \u00b0C with a heating rate of 2.5 \u00b0C/min. Temperature coefficient of dielectric constant ( \u03b1 \u03b5 , ppm/\u00b0C) was calculated from the slope of dielectric constant in the temperature range of 20\u201385 \u00b0C and the dielectric constant at 20 \u00b0C. A KEITHLEY 6517A high resistance meter was used to measure the leakage current of the samples under 400 V dc bias for 1 min. Microwave dielectric characteristics of the specimens were measured by the post resonant method, which consisted of parallel conducting plates and coaxial probes. A HP8753E network analyzer was used for the microwave measurement. The dielectric properties were calculated from the frequency of the TE 011 resonant mode. 3 Results and discussion The X-ray diffraction patterns of CuO/V 2 O 5 doped Bi 2 Zn 2/3 Ta 4/3 O 7 ceramics are shown in Fig. 1 . It can be seen that, even at a small amount of V 2 O 5 addition, XRD patterns differed from the sample of pure \u03b2-BZT. In the vicinity of 32.7\u201334.7\u00b0, the split-peak gradually evolved into single-peak. With V 2 O 5 addition higher than 0.3 wt.%, the fluorite structure was observed. However, the crystal structure of all CuO doped samples were characterized as monoclinic zirconolite structure as that of pure \u03b2-BZT ceramic, no secondary phase was observed using X-ray diffraction. As mentioned above, specimens based on composition of Bi 2 Zn 2/3 Ta 4/3 O 7 were sintered at 1030 \u00b0C. After doping CuO/V 2 O 5 into \u03b2-BZT, the sintering temperature of the samples decreased below 950 \u00b0C. This could be attributed to the liquid-phase sintering that promoted the densification of \u03b2-BZT ceramics very effectively [7] . The effects of 0.05 wt.% CuO/V 2 O 5 on the densification of \u03b2-BZT ceramics sintered at different temperature are shown in Fig. 2 . The density increased continually below 950 \u00b0C and then started to decrease slightly. All other specimens that doped with various CuO/V 2 O 5 additions had a same change tendency. The bulk density reaches a maximum at a fixed temperature with a certain addition. The larger amount of additions was used, the lower the temperature was. For V 2 O 5 doped specimens, the density gradually decreases with increasing of V 2 O 5 content. The decrease of density maybe associates with the change of phase structure in the finished specimen. The density of all CuO doped \u03b2-BZT specimens are above 8.82 g/cm 3 . The SEM micrographs are shown in Fig. 3 . The grain size of undoped sample was about 2\u20135 \u03bcm. The grain size decreased and the microstructure became dense with doping of CuO/V 2 O 5 . These results suggested that the doping of CuO/V 2 O 5 substantially decrease the grain size and change the microstructure of \u03b2-BZT ceramics. Pure \u03b2-BZT and V 2 O 5 doped ceramics had excellent electrical resistivity higher than 10 13 \u03a9 cm. These high values represent very good insulation resistance and hence very small leakage current in capacitor devices. For CuO doped specimens, the electrical resistivity decreased from 10 13 to 10 8 \u03a9 cm with increasing of the amount of CuO. Temperature dependence of dielectric constant ( \u03b5 ) and dissipation factor (tan \u03b4 ) is presented in Fig. 4 . When CuO content added to 0.2 wt.% and above, the temperature dependence of dielectric behaviors showed that the tan \u03b4 at low frequency increases with increasing of temperature. Combined with the electrical resistivity measurement, this phenomenon could be attributed to the conductance loss [8] . Fig. 5 shows the microwave dielectric properties of different CuO/V 2 O 5 doped samples. As increasing V 2 O 5 doping content, the dielectric constant and dissipation factor increased continuously both at 1 MHz and 4.9\u20135.6 GHz. Also, with increasing of V 2 O 5 content, the obvious change was the increase of the \u03b1 \u03b5 at 1 MHz from 75 to 137 ppm/\u00b0C and the decrease of Qf value from 6987 to 957. This result was due to the formation of the secondary phase. The enhanced dielectric constant in V 2 O 5 added \u03b2-BZT ceramics also could attribute to the contribution from the secondary phase. For CuO doped samples, the dissipation factor and temperature coefficient of dielectric constant were found to be sensitive to CuO addition. With increasing of CuO content the \u03b1 \u03b5 and tan \u03b4 increased at 1 MHz. The Qf values of \u03b2-BZT doped with CuO were higher than that of V 2 O 5 doped specimens, but they were lower than pure \u03b2-BZT. In general, Qf values are affected by the oxygen vacancies and electron concentration, impurities, grain boundaries, and microstructure [9] . The decrease of Qf value of CuO doped specimens was probably due to impurity grain boundaries and the decrease of grain size as confirmed by SEM photographs. Also, the lower electrical resistivity of the ceramics resulted in a higher conductance loss and thus lowered the Qf value. When both 0.05 wt.% CuO and 0.05 wt.% V 2 O 5 were added into \u03b2-BZT, the sintering temperature of ceramics specimens were also reduced down to 930 \u00b0C. The microwave dielectric properties were: \u03b5 =\u223c63 and Qf =\u223c6787 at \u223c5.35 GHz with \u03b1 \u03b5 =\u223c73 ppm/\u00b0C at 1 MHz. 4 Conclusions The structure and dielectric properties of CuO/V 2 O 5 doped \u03b2-BZT ceramics were investigated. The structure of CuO doped \u03b2-BZT ceramics was characterized as monoclinic zirconolite structure as that of pure \u03b2-BZT ceramic. The structure of V 2 O 5 doped \u03b2-BZT ceramics cannot maintain the monoclinic zirconolite structure even at lower doping amount. Therefore, CuO/V 2 O 5 were effective to lower the sintering temperature of \u03b2-BZT, while the microwave dielectric properties of the specimens were deteriorated by excess amount of CuO/V 2 O 5 . At room temperature and 1 MHz, as the addition of CuO increased from 0.01 to 1 wt.%, the dielectric constant of all the specimens was about 65.5, but dielectric loss and temperature coefficient of the dielectric constant gradually increased to a maximum value. With increase of V 2 O 5 content, a decrease in microwave dielectric properties was obtained. When both 0.05 wt.% CuO and 0.05 wt.% V 2 O 5 were added into \u03b2-BZT, the microwave dielectric properties were: \u03b5 =\u223c63 and Qf =\u223c6787 at \u223c5.35 GHz with \u03b1 \u03b5 =\u223c73 ppm/\u00b0C at 1 MHz.

Results showed that change of K/Na ratio in KNN induces a phase transition from ferroelectric to ergodic relaxor phase with a significant disruption of the long-range ferroelectric order, and correspondingly adjusts the ferroelectric-relaxor transition point T F-R to room temperature. Accordingly, giant strain of ~0.46% (corresponding to a large signal d33* of ~575 pm/V) which is comparable to that of Pb-based antiferroelectrics is obtained at a K/Na ratio of ~1, and the emergence of large strain response induced by the change of K/Na ratio of KNN can be well explained by the correlation between the position of ferroelectric-ergodic relaxor phase boundary in the BNKT-KxNN system and the tolerance factor t of the end number (KxNN). In situ high-energy X-ray scattering experiments with external field reveals that the large strain response in the studied system is likely related to the electric field-induced distortion from the pseudocubic structure. \u00a9 2013 The American Ceramic Society.",

The effects of sintering temperature and BT content on the grain orientation and dielectric, ferroelectric, piezoelectric properties of the textured BZT ceramics have been investigated. The piezoelectric coefficient d 33, strain level, normalized strain (S max/E max) level, and remnant polarization P r of the textured BZT ceramics first increased and then decreased with the rising of sintering temperature and BT template addition due to the high degree of orientation and relative high density. The textured BZT ceramics exhibit high anisotropy dielectric, ferroelectric and piezoelectric properties in the directions of parallel and perpendicular to the tape casting plane and the ceramics in parallel direction show better electric properties than those of the ceramics in perpendicular direction. The optimized sintering temperature and template content were obtained with the maximum piezoelectric coefficient d 33 = 234 pC/N, the maximum strain levels of 0.22% and the maximum normalized strain (S max/E max) level of 550 pm/V. \u00a9 2012 Elsevier B.V.

Their structure and dielectric properties were systematically characterized. The introduction of MgMoO4 resulted in a change in lattice constant of the perovskite phase and partial reaction between MgMoO4 and Ba0.5Sr0.5TiO3 occurred in the sintering process. Both X-Ray Diffraction (XRD) and Back-scattered Electron Images (BEI) analysis show the co-existence of three phase structures of BST, MgMoO4 and BaMoO4. With increasing of MgMoO4 content, the tunability of the composite ceramics was decreased due to the increase of the amount of non-ferroelectric phases. The Curie temperature Tc of the samples gradually shifted to low temperatures with increasing of MgMoO4 content. Dielectric constant can be adjusted in the range from 2035 to 150, meanwhile maintain a relatively high tunability and Q values. The sample with 20 wt% MgMoO4 possesses a tunability of 10 %, a low dielectric constant of 111 and an appropriate Q value of 183 (2.240 GHz), which meet the requirements of high power and impedance matching, thus making it a promising candidate for applications as electrically tunable microwave devices. \u00a9 2013 Springer Science+Business Media New York.",

This study focuses on the effect of the grain size on the electric properties and thermal stability of BIT ceramics. The BIT ceramic with different grain sizes from 4.2 \u03bcm to 0.28 \u03bcm were prepared by three sintering methods: normal sintering, two-step sintering and hot pressing sintering. Result shows that the problem of large leakage current of BIT ceramics can be solved by reducing grain size. The piezoelectric properties of BIT ceramics have a strong dependence on the grain size since two factors of internal stress and poling electric field strength both influences the degree of ferroelectric domain switching.

        "abstract": "Highlights \u25ba Li doped KNN thick films were prepared by a tape casting process. \u25ba The coercive fields decreased with the addition of Li ions. \u25ba The thick film with 6 mol% Li exhibited an optimized value of d 33 which was 92 pm/V. Abstract Lithium doped K 0.5 Na 0.5 NbO 3 (abbreviated as KNN\u2013 x L, with x = 0.02, 0.04, 0.06, 0.08) thick films with a thickness of about 20 \u03bcm were prepared by a tape casting process. The presence of Li ions promoted the microstructure of these thick films. Coercive fields ( E c ) of the thick films decreased with the addition of Li ions. Two phase transition temperatures, corresponding to T O \u2013 T and T C , were observed in the KNN\u2013 x L thick films. The sample with x = 0.06 exhibited an optimized value of d 33 (91.6 pm/V), which was attributed to the formation of a morphotropic phase boundary. Keywords Sodium potassium niobate Thick films Dielectric response Piezoelectricity 1 Introduction Piezoelectric thick films have drawn significant interests in recent years with the development of microelectromechanical systems (MEMS). They are widely used in micropumps, ultrasonic motors, resonators, high-frequency transducers and energy harvesters [1\u20133] . Thick films offer many advantages over bulk ceramics as components in various electronic devices. Up to now, most thick films used for industrial productions are lead-containing materials, which are harmful to the environment during the fabrication and disposal after usage. More and more studies focused on lead-free materials because of the urgent demands for environmental protection [4,5] . However, the low piezoelectric coefficients of lead-free materials restricted their industrial applications. Sodium potassium niobate (K 0.5 Na 0.5 NbO 3 or KNN) is one of the most promising lead-free piezoelectric materials, due to its relatively large piezoelectricity ( d 33 = 160 pC/N) and high Curie temperature ( T C = 420 \u00b0C). Wang et al. [6] fabricated KNN thick films by using a polyvinylpyrrolidone-modified chemical solution deposition method. The thick film had an optimized piezoelectric coefficient of 61 pm/V. Ryu et al. [7] reported a lead-free piezoelectric thick film, 0.948(K 0.5 Na 0.5 )NbO 3 \u20130.052LiSbO 3 , with a piezoelectric coefficient of 50 pm/V, by using an aerosol deposition method. These values are much inferior to that of PZT thick films (60\u2013210 pm/V). It has been shown that compositional modification is one of the effective approaches to improve piezoelectric properties of lead-free materials. Recently, it was found that there is a morphotropic phase boundary (MPB) in KNN ceramics doped with 6% Li [8,9] . The coexistence of tetragonal and orthorhombic phases made polarization more available and thus enhanced the piezoelectric performance of KNN [10,11] . Saito et al. [12] found that textured KNNL ceramics had a piezoelectricity comparable to that of PZT ceramics. Piezoelectric thick films can be prepared by many techniques, such as screen printing, tape casting, composite sol\u2013gel, electrophoretic deposition, ink-jet printing, and aerosol deposition [13\u201316] . Tape casting is among the most convenient and economic processes to fabricate thick films. This technique has been widely used for large-scale fabrication of piezoelectric thick films. In the present work, it was used to prepare lithium-doped KNN lead-free thick films. The effect of Li concentration on microstructure and electrical properties of the thick films was investigated. 2 Experimental Potassium carbonate (99.0%), sodium carbonate (99.8%) and niobium oxide (99.0%) powders were used as raw materials to synthesize K 0.5 Na 0.5 NbO 3 (KNN). The starting powders were mixed and ball milled in dehydrated alcohol for 24 h. The mixture was dried at 110 \u00b0C and calcined at 850 \u00b0C for 1 h. Lithium carbonate was added into the KNN powders to prepare tape casting slurry, with compositions of KNN\u2013 x L ( x = 0.02, 0.04, 0.06 and 0.08). Toluene and dehydrated alcohol were mixed with a mass ratio of 2:1 to as solvent. The KNN\u2013 x L powders with a mass percentage of 55% were dispersed into the solvent and milled for 15 h. Consequently, LS bonder with a mass percentage of 15% (provided by LING-GUANG electric chemical materials Technology Corporation, Zhaoqing, China) was added into the suspensions and milled for another 3 h to obtain stable casting slurry. KNN\u2013 x L thick films were fabricated with a conventional tape-caster with a gap of 100 \u03bcm under the blade. The green thick films were dried, cut and pressed on Al 2 O 3 substrates coated with Ag\u2013Pd bottom electrodes. The thick films were stuck on the substrates by using isostatic pressing at 200 MPa. They were annealed at 550 \u00b0C for 5 h to remove organic substances at a rate of 1 \u00b0C/min and then sintered at 1000 \u00b0C for 2 h at a heating rate of 3 \u00b0C/min. Phase compositions of the thick films were investigated by using an X-ray diffractometer (XRD, Bruker D8 Advanced, Germany) with Cu K\u03b1 radiation. Microstructures and chemical compositions of the samples were examined by using a scanning electron microscopy (SEM, JSM EMP-800) with an EDS detector. In order to determine electrical properties of the specimens, gold electrodes with a thickness of 80 nm and a diameter of 1 mm were sputtered on surfaces of the thick films. Temperature dependences of dielectric constant and loss tangent of the thick films were measured from room temperature to 420 \u00b0C at frequencies of 1, 10, 100 and 1000 kHz by using a high-precision LCR meter (HP 4284A). Hysteresis loops and longitudinal displacement curves of the thick films were measured by using a ferroelectric test system (Precision Premier II, made in USA), connected with a miniature plane-mirror interferometer and accessory laser interferometric vibrometer (SP-S 120/500 Model, made in Germany). 3 Results and discussion Fig. 1 shows XRD patterns of the KNN\u2013 x L thick films. All samples are of single phase perovskite structure. No secondary phase is detected. The orthorhombic phase is characterized by the splitting peak at 2 \u03b8 \u2248 46\u00b0, where a higher peak is followed by a lower peak, whereas, the tetragonal phase exhibits a lower peak followed by a higher peak at 2 \u03b8 \u2248 46\u00b0 [17,18] . Fig. 1 b shows the detailed XRD patterns of the KNN\u2013 x L thick films over 44.5\u201347.5\u00b0. Pure KNN thick film is orthorhombic phase. Intensities of the two split peaks tend to be equal gradually with increasing concentration of Li, which indicates a phase transition from orthorhombic to tetragonal symmetry. This phase transition occurred at about x = 0.06, which suggests the coexistence of orthorhombic and tetragonal phases, i.e., the existence of a MPB, in the KNN\u2013 x L thick film with x = 0.06. Besides, a shift in diffraction peaks to lower angles with the increase of Li can also be observed. It is known that volatilization of alkali ions would happen at high temperatures which left cation vacancies and consequently made the KNN lattice shrink [19] . Li ions are supposed to occupy these vacancies at first and then enlarged the lattice which is responsible for the shift in the diffraction peaks. The limitation of Li ions in KNN lattice seems to be x = 0.06 according to Fig. 1 b because the peaks exhibit no shift above x = 0.06. Fig. 2 a\u2013e shows SEM surface images of the thick films. Grain size increases slightly with the addition of Li ions. This could be attributed to the low melting point of Li 2 CO 3 , which formed liquid phase that promoted sintering behaviors of the doped films. Furthermore, the addition of Li ions distorted the KNN lattice, which resulted in more defects that also could promote the grain growth of the films. The linear intercept measurement was applied to determine the average grain size of the thick film. Average grain sizes of the KNN\u2013 x L thick films are 1.1, 1.4, 1.5, 1.7 and 1.7 \u03bcm for x = 0, 0.02, 0.04, 0.06, and 0.08. However, quite a number of distinct pores are still observable in the thick films even x is as high as 0.08. The porous microstructures are mainly caused by volatilization of the organic substances and alkali components [20] . Chemical compositions of the thick films measured with EDS are listed in Table 1 . All samples exhibit a slight fluctuation in compositions. The concentrations of K and Na are always lower than 0.5, due to their volatilization. Fig. 3 shows temperature dependences of dielectric constant and loss tangent of the KNN\u2013 x L thick films. Both the O\u2013T (orthorhomibic\u2013tetragonal) phase-transition ( T O \u2013 T ) and Curie point ( T C ) are observed in all the KNN\u2013 x L thick films. T O \u2013 T and T C of KNN ceramics are 200 \u00b0C and 420 \u00b0C, respectively. T C shifted gradually to higher temperatures as the Li content is increased. At the same time, T O \u2013 T shifted to low temperatures with increasing content of Li, indicating that the addition of Li stabilized the tetragonal phase. This result is also observed in Li doped KNN ceramics [21] . Dielectric loss tangents of the thick films are all less than 4.0% at 300 \u00b0C, which are slightly higher than that of KNN ceramics (3%) [22] . Fig. 4 shows P \u2013 E hysteresis loops of the KNN\u2013 x L thick films. Coercive fields ( E c ) of the samples are illustrated in Fig. 5 . E c decreases with increasing content of Li. The presence of defects and pores caused by the volatilization of alkali components might restrict domain switching. The addition of Li not only compensated the charged defects but also improved the densification of the thick films. As a result, the domains became to more easily switchable, thus leading to a reduction in E c . Specifically, E c of the thick film with x = 0.08 is as low as 7.92 kV/cm, which is far lower than that of pure KNN and comparable with that of KNN ceramics [23] . However, an obvious hysteresis behavior is observed in these thick films. Two reasons are responsible for this kind of hysteresis behavior according to Guo et al. [24] . One is the effect of oxygen vacancy and the other is that of space charge. Both mechanisms can happen in our Li doped KNN thick films because of their porous microstructures and the volatilization of alkali components. It has been observed in PZT thick films that substrate clamping effect introduced stresses in the films, which distorted the unit cells and thus decreased the effectiveness of polarization process. It is important to recognize the significance of the clamping effect when citing piezoelectric data [25] . Therefore, it is typical to use d 33 values as piezoelectric constants to characterize thick-films so as to differentiate them from bulk ceramics. Here, we use dynamic d 33 to characterize our thick films. Fig. 6 shows longitudinal displacement curves of the samples with x = 0, 0.02 and 0.06. At bipolar electric field, the sample with x = 0.06 has the largest strain. Fig. 7 shows unipolar driven longitudinal strains of the samples with x = 0.02, 0.06 and 0.08. The strain values increase almost linearly and are proportional to the applied field. Longitudinal piezoelectric constants ( d 33 ) were calculated from the slopes of the field-strain plots, as shown in Fig. 7 . d 33 of the thick film with x = 0.06 reaches a maximum value of 92 pm/V, which is much higher than the reported values of KNN thick film [6] and 0.948(K 0.5 Na 0.5 )NbO 3 \u20130.052LiSbO 3 thick film [7] . The enhanced piezoelectric properties can be attributed to the existence of MPB. 4 Conclusions Li doped KNN thick films were fabricated by a tape casting method. A MPB was observed in the sample with Li concentration of x = 0.06. A very low E c (7.92 kV/cm) was observed in the sample with x = 0.08. The addition of Li also decreased the values of T O \u2013 T and T C . T C shifted to higher temperatures with increasing content of Li, whereas T O \u2013 T shifted to low temperatures. Dielectric loss tangents of the doped thick films were slightly increased as compared to that of KNN ceramics. A maximized piezoelectric constant of 91.6 pm/V was observed in the sample with x = 0.06.

        "abstract": "Textured K 0.5 Na 0.5 NbO 3 thick film was prepared by the reactive templated grain growth method. The effects of Mn 2+ doping on the phase structure, microstructure and electrical properties of the K 0.5 Na 0.5 NbO 3 textured thick film were investigated. The grain orientation degree decreased with increasing Mn 2+ and reduced to 50% for the thick film with 5 mol% Mn 2+ . The addition of Mn 2+ improved the microstructure of the thick film. The electric properties of the thick film were also enhanced because of the high densification, the vacancy compensation effect and the acceptor doping effects of Mn 2+ . The K 0.5 Na 0.5 NbO 3 thick film with 2 mol% Mn 2+ doping possessed the optimum properties: P r = 3.05 \u03bcC/cm 2 , E c = 4.79 kV/cm, J = 4.6 \u00d7 10 \u22126 A/cm 2 (at 25 kV/cm) and d 33 * = 124 \u2009 pm/V . Keywords A. Films A. Tape casting C. Electrical properties D. Perovskites 1 Introduction The miniaturization of electroceramics has shown an increasing trend for the development of microelectromechanical systems (MEMS) such as microsensors and microactuators [1,2] . The thick film technology is appreciated for integration, not only for its low dimension, but also for the rapid reduction on the driving voltage. Meanwhile, the evident deteriorate electric properties of the thin films can be avoided for the thick films. Lead zirconate titanate (PZT) is the most popular materials for thick film [3] . However, lead free piezoelectric materials have been desired from the viewpoint of environmental protection over the last few years, especially after the announcement of draft directives on waste from electrical and electronic equipment (WEEE) and restriction of hazardous substances (RoHS) [4] . The K 0.5 Na 0.5 NbO 3 -based (KNN) compositions have shown great advantages over other typical lead free piezoelectric material system [5] . However, the piezoelectric properties of the KNN materials are still inferior to PZT based ones. In recent years, the composition modification is widely used to improve the performance of the KNN ceramics, besides, the grain oriented technology is also considered to be one of the effective approaches to improve the piezoelectric properties of the ceramics [6,7] . Whereas, the high loss tangent comes to be a significant problem for the KNN textured thick film. The addition of manganese acceptor has been verified to be an effect way to reduce the loss tangent of the KNN ceramics [8,9] . Furthermore, the volatilization of alkali metal ions in the thick film supposed to be more seriously than in bulk ceramics. The addition of Mn 2+ compensates the charge defects generated from the volatilization of alkali metal ions to improve the properties of the thick film. In our present work, the Mn ions were added to decrease the loss tangent of the KNN textured thick film. The influence of the Mn 2+ dopant on the phase structure, microstructure and electric properties of the KNN textured thick film was investigated. 2 Experimental The KNN powders were prepared with sodium carbonate (Na 2 CO 3 , 99.8%, Sinopharm Chemical Reagent Co. Ltd), potassium carbonate (K 2 CO 3 , 99.0%, Sinopharm Chemical Reagent Co. Ltd) and niobium oxide (Nb 2 O 5 , 99.5%, Sinopharm Chemical Reagent Co. Ltd) as raw materials via the conventional solid state reaction. The KNN\u2013 x Mn matrix was prepared with the pre-calcined KNN powders and x mol% ( x = 0, 1, 2 and 5) manganese carbonate (Mn 2 CO 3 , Mn 44%, Alfa Aesar, A Johnson Matthey Company). The NaNbO 3 (NN) plate-like particles with the sharp of a thickness about 0.5 \u03bcm and a width ranged from 10 \u03bcm to 20 \u03bcm were fabricated by the double molten salt method with Bi 2.5 Na 3.5 Nb 5 O 18 as precursor. The mixture of 90 wt% matrix and 10 wt% plate-like NN particles was added in the solution composed with toluene and dehydrated alcohol and then this suspension was milled for 15 h. The binder (LS model, produced by Lingguang Electric Chemical Materials Technology Corporation, Zhaoqing City, China) was added to the suspension and milled for anther 3 h to stabilize the casting slurry. This slurry was tape cast with conventional tape-casting equipment. The green thick film was cut and pressed on the alumina substrate with Ag\u2013Pd bottom electrode by isostatic pressing under 200 MPa. The green film was annealed at 550 \u00b0C to remove the organic substance and then sintered at 1150 \u00b0C for 2 h. Phase structures of the thick films were investigated with X-ray diffraction (XRD, D8 Advanced, Bruker AXS, Germany) with Cu K\u03b1 radiation. The degree of the grain orientation can be represented by the Lotgering's factor F [10] . The microstructures of the specimens were examined by scanning electron microscopy (SEM, JSM EMP-800, Japan). In order to determine the electric properties of the specimens, the gold electrode with a thickness of 80 nm and a diameter of 0.5 mm sputtered on the surfaces of the thick films. Frequency dependences of the dielectric constant and loss were measured from 10 kHz to 2 MHz by using a high-precision LCR meter (HP 4284A, Aglient, USA). Leakage current density J was tested with electrometer (Keithley 6517A, Cleveland OH, USA). The P \u2013 E hysteresis loops and the longitudinal displacement field curves were measured by the ferroelectric test systems (Precision Premier II, USA) connected with a Miniature Plane-mirror Interferometer and the accessory Laser Interferometric Vibrometer (SP-S 120/500 Model, German). 3 Results and discussion Fig. 1 shows the XRD patterns of the Mn 2+ doped KNN textured thick films. All thick films possess perovskite structures. Some impurity phases identified as K 2 Nb 8 O 21 and Nb 2 O 5 are observed. The peak intensity of impurity phase increases with increasing Mn 2+ concentration. The appearance of impurity phase properly dues to the volatilization of the alkali metal ions at 1150 \u00b0C. The detailed XRD patterns performed in the 2 \u03b8 range of 39.5\u00b0\u201340.5\u00b0 and 45.5\u00b0\u201347\u00b0 are shown in Fig. 1 (b) and (c), respectively. The single peak near 40\u00b0 and 46\u00b0 indicates the pseudocubic structure of the textured KNN thick film. The structures of the samples added with Mn 2+ have the features of tetragonal symmetry evidenced by the splitting of (0 0 2)/(2 0 0) peaks at 2 \u03b8 around 46\u00b0. This indicates that the crystal structure of the KNN thick film transformed from a pseudocubic into tetragonal phase with the addition of the Mn 2+ . The F values calculated from the XRD patterns of the thick films also illustrate in Fig. 1 (a). The F value gradually decreased from 63 to 50% with the addition of Mn 2+ . Fig. 2 shows the SEM micrographs of the textured KNN thick films with x = 0, 0.01, 0.02 and 0.05. The thick film without Mn 2+ doping has a very loose structure and a large amount of the pores owing to the residual organic vehicle and the volatilization of the alkali metal ions. The distribution of the porosity decreases after a small amount of Mn 2+ adding. The doping Mn 2+ leads to the distortion of crystalline lattice and then promotes the sintering process. However, an abnormal large grain marked with A in Fig. 2 (d) is observed in the thick film with x = 0.05. The abnormal grain growth usually occurred in the presence of the liquid phase, so the addition of Mn 2+ in the thick film seems to lead to the liquid phase. Whereas, the presence of the liquid phase needs more detailed analysis which does not conducted in our present study. Fig. 3 illustrates the polarization hysteresis loops of the Mn 2+ doped KNN textured thick films. The polarization hysteresis loop of the KNN textured thick film shows a low remnant polarization ( P r ) of 0.77 \u03bcC/cm 2 . This may caused by the structure defects such as porosity and charge defects induced by the volatilization of the alkali metal ions. These defects deplete part of the electric field and reduce the effective electric field applied on the thick film. The P r was found to increase with the addition of Mn 2+ as shown in the inset of Fig. 3 and reached to its maximum value of 6.82 \u03bcC/cm 2 for the thick film with x = 0.05. The coercive electric field ( E c ) decreased with increasing Mn 2+ concentration and reaches to a minimum value of 4.79 kV/cm for the thick film with x = 0.02. These should be attributed to the improved microstructure and the compensation effect on the charge defects by the addition of Mn 2+ . Fig. 4 shows the frequency dependences of the dielectric constant ( \u025b ) and loss tangent (tan \u03b4 ) of the thick films. KNN thick films with Mn 2+ doping displayed a large dielectric constant in contrast to undoped ones. The dielectric loss tangent of the films was reduced by Mn 2+ doping at low frequency. The improvement in dielectric properties of KNN\u2013 x Mn thick films should be attributed to the formation of the defect complex Mn Nb \u2013V O [11] . This defect complex had a dipole moment and could be oriented to align the dipole along the direction of the applied electric field. Furthermore, the addition of Mn 2+ compensated the charge defects which induced by the volatilization of alkali metal ions and enhanced the microstructure of the thick film. The reduction oxygen vacancies and the less porosity microstructure reduced the conduction loss consequently the dielectric loss at low frequency decreased. Fig. 5 shows the J \u2013 E characteristics of the KNN\u2013 x Mn thick films. Two distinctive regions are observed for KNN\u2013 x Mn ( x = 0, 0.01, 0.02 and 0.05) thick films. The leakage current density increases rapidly in the low voltage region and remains in a narrow band in the high voltage [12] . The leakage current density of the thick film with x = 0.05 stabilizes even at the voltage above 2 kV/cm. The leakage current density demonstrates significant improvement with the increase of Mn 2+ . It reduced from the order of 10 \u22124 to 10 \u22128 A/cm 2 with adding 5% Mn ions. The low leakage current in the Mn 2+ doped KNN thick films can be ascribed to the acceptor behavior of Mn ions and the compensation effect on the charge defects. The Mn ions formed the defect complex Mn Nb \u2013V O and then decreased the free oxygen vacancy concentration. Furthermore, the charge defects residual by the volatilization of alkali metal ions is compensated by the addition of Mn 2+ and consequently reduced the leakage current density. Fig. 6 shows the unipolar electric field-induced strain curves of KNN\u2013 x Mn ( x = 0, 0.01, 0.02 and 0.05) thick films. The d 33 * defines as S max / E max and the values are illustrated in Fig. 6 . The S max and E max presented the maximum strain and electric field, respectively. The d 33 * of textured KNN thick film (KNN10) showed 61 pm/V which is 60% higher than that of non-textured KNN (KNNp) thick film ( d 33 * = 38 \u2009 pm/V ). The d 33 * increases with the addition of Mn 2+ and reaches to the maximum value of 124 pm/V for the thick film with x = 0.02. The addition of Mn 2+ reduces the charge defects and result in the decrease of the pinning centre which facilitated the domain switch. Furthermore, the decrease of the leakage current density weakens the internal electric field and thus increases the effective electric field. The d 33 * decreases to 103 pm/V by adding with 5% Mn 2+ . The excessive Mn ions are supposed to act as an acceptor and became to be the new domain pinning centre which result in the reduction of d 33 * value. 4 Conclusions The textured KNN thick films with Mn 2+ doping were fabricated by using NN plate-like templates via the RTGG method. The films exhibit a perovskite structures. The Mn 2+ dopants improve the microstructure of the thick film with x = 0.02. The F value of the thick film decreases a little with the addition of Mn 2+ . The addition of Mn 2+ effectively improves the ferroelectric polarization of the thick film. The P r increases to 6.82 \u03bcC/cm 2 for the thick film with x = 0.05. The dielectric constant of the films is also improved and the dielectric loss is reduced at low frequency. A significant reduction in the leakage current density can be achieved by adding Mn 2+ in the thick film. The piezoelectric constant d 33 * increases with the addition of Mn 2+ and reaches to the maximum value of 124 pm/V for the thick film with x = 0.02.

The material was synthesized by conventional ceramic method and microwave sintering processing.\n The dielectric properties were studied as a function of frequency and temperature. Dielectric constant of Bi2Zn2/3Ta4/3O7 ceramics prepared from microwave is slightly smaller than that of the conventional sintered ones. The dissipation factor\n and temperature coefficient of dielectric constant are low for microwave-sintered samples. Microwave sintering of Bi2Zn2/3Ta4/3O7 ceramics led to higher densification and the fine microstructure in much shorter time duration compared to conventional procedures,\n improved microstructure and dielectric properties. To achieve the same densification, it requires 4\u00a0h of soaking at the same\n temperature in conventional sintering process. Microwave sintering method may lead to energy savings because of rapid kinetics\n of synthesis.",

Effects of sintering conditions on the grain growth process of textured-BT ceramics were investigated. Orientation degree increased initially and then decreased with increasing soaking time. The ceramics were composed of equiaxed matrix grains and brick-like template particles. The brick-like particles aligned parallel to the casting direction by observing from SEM images. A (h00)-preferred orientation was confirmed by SAED and XRD patterns. Mechanism of grain growth in textured-BT ceramics was studied. Both consumption of matrix by templates and grain growth of templates determined the orientation degree of ceramics. The kinetic mechanism for grain orientation was also discussed by the simplified phenomenological kinetic equation. The average activation energies were 364 kJ/mol for matrix grain and 918 kJ/mol for template particle, respectively. Finally, a dense ceramic with 85% grain orientation was obtained after sintering at 1400 \u00b0C for 2 h.",

In this study, flexible nanocomposites containing newly structured one-dimensional (1D) BaTiO@AlO nanofibers (BT@AO NFs) and the ferroelectric polymer poly(vinylidene fluoride) (PVDF) matrix were prepared and systematically studied. The 1D BT@AO NFs, where BaTiO nanoparticles (BT NPs) were embedded and homogeneously dispersed into the AO nanofibers, were successfully synthesized via an improved electrospinning technique. The additional AO layer, which has moderating dielectric constant, was introduced between BT NPs and PVDF matrixes. To improve the compatibility and distributional homogeneity of the nanofiller/matrix, dopamine was coated onto the nanofiller. The results show that the energy density due to high dielectric polarization is about 10.58 J cm at 420 MV m and the fast charge-discharge time is 0.126 \u03bcs of 3.6 vol % BT@AO-DA NFs/PVDF nanocomposite. A finite element simulation of the electric-field and electric current density distribution revealed that the novel-structured 1D BT@AO-DA NFs significantly improved the dielectric performance of the nanocomposites. The large extractable energy density and high dielectric breakdown strength suggest the potential applications of the BT@AO-DA NFs/PVDF nanocomposite films in electrostatic capacitors and embedded devices.",

The effect of the various Al/Si ratios on the phase evolution, microstructure, dielectric properties, and energy storage density, and the relationship between the breakdown strength properties and the activation energy E a of BSN-AS glass-ceramics, were investigated. The results reveal that the microstructure of BSN-AS glass-ceramics gradually becomes dense and uniform, and the phenomenon of reunited grains is effectively improved in a certain range of Al/Si ratios. With the Al/Si ratios increasing, the breakdown strength increases to a maximum value and then decreases drastically. For the relationship between breakdown strength properties and activation energy E a, it was found that the various trends between breakdown properties and activation energy E a of the BSN-AS glass-ceramics are opposite. In this study, the energy storage densities reach 4.8 J/cm3 by adjusting the Al/Si ratios in the BSN-AS glass-ceramics.",

Here, NaNbO3 (NN)/polymer composites, especially two-dimensional (2D) NN platelets, were used to create new composite films for energy storage applications for the first time. The trilayered architecture composites comprised of two outer layers of 2D NN platelets dispersed in a poly(vinylidene fluoride) (PVDF) matrix to provide high dielectric constant and a middle layer of pristine PVDF to offer high breakdown strength. The breakdown strength and energy density of the trilayered architecture composite films were improved significantly via tailoring the contents of the 2D NN platelets. The composite films with an optimized filler content illustrate a high discharge energy density of 13.5 J cm\u22123 at 400 MV m\u22121, far more than the best commercial biaxially- oriented polypropylenes. Moreover, the composite films show a superior power density of 2.68 MW cm\u22123 and ultra-fast discharge speed of 0.127 \u03bcs. Finite element simulation further revealed the breakdown strength and energy density of the composite films were much enhanced compared to the corresponding single layer composite films. Therefore, the new trilayered architecture composite films can be applied as an alternative promising high-performance electrostatic capacitor material.",

        "abstract": "Amorphous Ge8Sb92 thin films with various thicknesses were deposited by magnetron sputtering. The crystallization kinetics and optical properties of the Ge8Sb92 thin films and related scaling effects were investigated by an in situ thermally induced method and an optical technique. With a decrease in film thickness, the crystallization temperature, crystallization activation energy and data retention ability increased significantly. The changed crystallization behavior may be ascribed to the smaller grain size and larger surface-to-volume ratio as the film thickness decreased. Regardless of whether the state was amorphous or crystalline, the film resistance increased remarkably as the film thickness decreased to 3 nm. The optical band gap calculated from the reflection spectra increases distinctly with a reduction in film thickness. X-ray diffraction patterns confirm that the scaling of the Ge8Sb92 thin film can inhibit the crystallization process and reduce the grain size. The values of exponent indices that were obtained indicate that the crystallization mechanism experiences a series of changes with scaling of the film thickness. The crystallization time was estimated to determine the scaling effect on the phase change speed. The scaling effect on the electrical switching performance of a phase change memory cell was also determined. The current-voltage and resistance-voltage characteristics indicate that phase change memory cells based on a thinner Ge8Sb92 film will exhibit a higher threshold voltage, lower RESET operational voltage and greater pulse width, which implies higher thermal stability, lower power consumption and relatively lower switching velocity.",

In this article, 1D lead-free 0.5(BaCa)TiO-0.5Ba(ZrTi)O nanofibers (BCZT NFs) were prepared via electrospinning, and their formation mechanism was systematically studied. Polypropylene acyl tetraethylene pentamine (PATP) grafted into the surface of BCZT NFs was embedded in the polymer matrixes, which effectively improved the distribution and compatibility of the fillers via chemical bonding and confined the movement of the charge carriers in the interface filler-matrix. The energy density at a relatively low electric field 380 MV m was increased to 8.23 J cm by small loading of fillers, far more than that of biaxially oriented polypropylene (BOPP) (\u2248 1.2 J cm at 640 MV m). Moreover, the nanocomposite loaded with 2.1 vol % BCZT@PATP NFs exhibits a superior discharge speed of \u22480.189 \u03bcs, which indicates the potential application in practice. The finite element simulation of electric potential and electric current density distribution revealed that the PATP grafted into the BCZT NFs surface could significantly improve the dielectric performances. This work could provide a new design strategy for high-performance dielectric polymer nanocomposite capacitors.",

        "abstract": "The development of new generation dielectric materials toward capacitive energy storage has been driven by the rise of high-power applications such as electric vehicles, aircraft, and pulsed power systems. Here we demonstrate remarkable improvements in the energy density and charge-discharge efficiency of poly(vinylidene fluoride) (PVDF) upon the incorporation of core-satellite structures, namely NaNbO3(NN)@polydopamine (PDA)@Ag nanowires. As compared to the NN NWs/PVDF and NN@PDA NWs/PVDF nanocomposites, the NN@PDA@Ag NWs/PVDF nanocomposites exhibit greatly enhanced energy density and significantly suppressed energy loss. As a result, the NN@PDA@Ag NWs/PVDF nanocomposite films with optimized filler content exhibit an excellent discharge energy density of 16.04 J cm-3 at 485 MV m-1, and maintain a high discharge efficiency of 62.8%. Moreover, the corresponding nanocomposite films exhibit a superior power density of 2.1 MW cm-3 and ultra-fast discharge speed of 153 ns. Ultimately, the excellent dielectric and capacitive properties of the polymer nanocomposites could pave the way for widespread applications in modern electronics and power modules.",

The X-ray diffraction and the field emission scanning electron microscopy were investigated the phase composition and microstructure for the BST-BBAS glass-ceramics added with rare-earth additions, then the temperature-dependent dielectric properties and the voltage-withstand measurements were applied to study the effect of rare-earth additions on the dielectric energy storage density. These results show that the certain content of rare-earth additions can optimize the microstructure and phase structure effectively. And with the decrease of ionic radiuses of rare-earth elements, the microstructure of the glass-ceramics become more uniform. When added with 0.5\u00a0mol% Yb 3+ , the theoretical energy storage density of the BST-BBAS glass-ceramics gets the largest value of 3.5\u00a0J/cm 3  which is about 1.8 times compared to the undoped one.",

The nanocomposites exhibited increased dielectric constant and improved breakdown strength. Dielectric constants of the nanocomposite with surface hydroxylated BST\u207bNPs (BST\u207bNPs\u207bOH) were higher as compared with those of their untreated BST\u207bNPs composites. The sample with 40 vol % BST\u207bNPs\u207bOH had a dielectric constant of 36 (1 kHz). Different theoretical models have been employed to predict the dielectric constants of the nanocomposites, in order to compare with the experimental data. The BST\u207bNPs\u207bOH/PVDF composites also exhibited higher breakdown strength than their BST\u207bNP/PVDF counterparts. A maximal energy density of 3.9 J/cm\u00b3 was achieved in the composite with 5 vol % BST\u207bNPs\u207bOH.

The dielectric properties, energy storage density, and discharge properties were investigated with the variation of the Na/Sr molar ratio. By varying the Na/Sr ratio, the energy storage density raises up to a high value of 10.09\u00a0J/cm 3 . With the variation of the Na/Sr ratio, both dielectric breakdown strength and discharge efficiency have an opposite change trend with the activation energy that reflects the interface polarization of the glass-ceramics. In contrast, for Na/Sr\u00a0=\u00a01/2, the glass-ceramic has the lower activation energy, which indicates that its interfacial polarization is weaker due to a fine microstructure. Thus, the glass-ceramics for Na/Sr\u00a0=\u00a01/2 have the characteristics of the higher breakdown strength of 2074\u00a0kV/cm and the higher discharge efficiency of 90.1%. Then it may contribute to the high energy storage density capacitor.",

A systematic study was investigated on the effect of BT@Al 2 O 3  NF filler introduction on the discharged energy density performance of the nanocomposite. Al 2 O 3  shell dramatically reduces the leakage current by prevent the contact between BT NF fillers in nanocomposites and minimize the Maxwell-Wagner-Sillars interfacial polarization, which results in the enhancement of the breakdown strength of nanocomposites films. Simultaneously, the nanocomposites have higher maximum polarization and lower the remnant polarization than that of PVDF films under the same electric field. The maximum discharged energy density of the nanocomposites with 2.5\u00a0vol% BT@Al 2 O 3  NF reaches 7.1\u00a0J/cm 3  at 3800\u00a0kV/cm with an efficiency of above 65.1%. This work may provide an effective solution for enhancing the discharged energy density of nanocomposites films.",

It was found that dielectric loss with the increase of K 2 O content increases owing to the un-crystallized K 2 O into the glass network, while dielectric breakdown strength firstly increases and then decreases due to the competition between two physical mechanisms, i.e., interfacial polarization and bridging-oxygen bond broken by the non-bridging oxygen ions. With the increase of K 2 O content, energy-storage density firstly increased up to 12.06\u00b10.69\u00a0J/cm 3  with a high breakdown strength of 1973\u00a0kV/cm, and then decreased.

XRD results showed Sr 6 Nb 10 O 30 , SrNb 2 O 6 , NaSr 2 Nb 5 O 15  with tungsten bronze structure and NaNbO 3  with the perovskite structure. With the decrease of crystallization temperature, dielectric constant firstly increased and then decreased, while breakdown strength (BDS) was increased. High BDS of the glass-ceramics is attributed to the dense and uniform microstructure at low crystallization temperature. The optimal dielectric constant of 140\u00b17 at 900\u00a0\u00b0C and BDS of 2182\u00b1129\u00a0kV/cm at 750\u00a0\u00b0C were obtained in SNNS glass-ceramics. The theoretical energy-storage density was significantly improved up to the highest value of 15.2\u00b11.0\u00a0J/cm 3  at 800\u00a0\u00b0C, which is about 5 times than that at 950\u00a0\u00b0C.

In this work, 1\u20133 type nanocomposites combining BaTiO 3  nanotubes (BT NTs) and poly(vinylidene fluoride) (PVDF) were prepared by a solution cast method. The BT NTs were synthesized by facile coaxial electrospinning and were coated with a dense and robust dopamine layer, which effectively improved the filler-matrix distributional homogeneity and compatibility. The 10.8\u00a0vol% BT-DA NTs/PVDF nanocomposites possessed an excellent dielectric constant of 47.05, which is approximately 569% greater that of the pristine PVDF (8.26) and 150%\u2013350% higher than that of the other PVDF nanocomposites loaded with similar ceramic filler contents, e.g., nanoparticles, nanowires, and nanofibers. The highest energy density of 7.03\u00a0J\u00a0cm \u22123  at a relatively low field of 330 MV m -1  was obtained via small loaded of the fillers, which is approximately 625% greater than for biaxially oriented polypropylenes (BOPP) (1.2\u00a0J\u00a0cm \u22123  at the field of 640\u00a0MV\u00a0m \u22121 ).

        "abstract": "Polymer nanocomposites with high energy density have potential applications in advanced electronics and electric power systems. The inevitable electrical mismatch between nanofillers and the polymer matrix could compromise the energy storage capability and dielectric properties of the polymer nanocomposites. Herein, novel core\u2013double-shell structured BaTiO3@TiO2@Al2O3 nanofibers (BT@TO@AO NFs) were prepared via a one step method, and were incorporated into poly(vinylidene fluoride) (PVDF). The novel design of gradually varying the multilayer hierarchical interface was advantageous to alleviating the local electric field and electric current density intensification in the filler/polymer system. As compared with the nanocomposites loaded with BT NFs and BT@TO NFs, the nanocomposites filled with BT@TO@AO NFs exhibit much decreased dielectric loss, enhanced breakdown strength, and suppressed leakage current densities. Simulations were carried out to verify that the new core\u2013double-shell structure significantly enhances the breakdown strength and energy density. As a result, the nanocomposite films loaded with 3.6 vol% BT@TO@AO NFs show a maximum energy storage density (Ue) of 14.84 J cm\u22123 at 450 MV m\u22121, which is about twelve times greater than that of biaxially oriented polypropylene (BOPP) (\u22481.2 J cm\u22123 at 640 MV m\u22121). Moreover, the nanocomposite exhibits a superior power density of 4.7 MW cm\u22123 and an ultra-fast discharge speed of 0.37 \u03bcs. This research opens up a convenient and effective way for designing high-performance dielectric polymer nanocomposites.",

        "abstract": "Abstract   Potassium barium niobate-based glass ceramics doped with different proportion of Gd 2 O 3  were fabricated by conventional melts and controllable crystallization. The influence of Gd 2 O 3  content was further investigated on the phase compositional change, energy storage performance and charge-discharge properties of the optimized glass ceramics (crystallization temperature 900\u00a0\u00b0C). The microstructure has been remarkably transformed through the addition of Gd 2 O 3 . On the basis of the results, the doping of 1.0% Gd 2 O 3  achieved a remarkable improvement on the energy storage density that reached 12.14\u00a0J/cm 3  with a dielectric breakdown strength (BDS) of 1818\u00a0kV/cm and dielectric constant of 83. The discharge efficiency of 80% and discharge time of 25\u00a0ns were obtained in the glass ceramics with 1.0% Gd 2 O 3 , which illustrated the excellent charge-discharge properties of Gd 2 O 3 -doped glass ceramics.",

The results show that a small amount of MnO 2  doping of the SBN-glass-ceramics can make their microstructure become denser and more uniform and MnO 2  doping of the SBN-glass-ceramics, as a grain growth inhibitor, has an evident effect on the reduction of grain sizes. The Mn ions exist in the form of Mn 3+  and Mn 4+  ions in the SBN-glass-ceramics, as confirmed by XPS measurements and Mn 3+  and Mn 4+  ions easily form charge defect complexes, which causes the leakage current densities of the SBN-glass-ceramics to obviously decrease. And a small amount of MnO 2  doping of the SBN-glass-ceramics can effectively decrease the dielectric loss of the materials. When 0.05\u00a0mol% MnO 2  is added to the SBN-glass-ceramics, the BDS is up to 1470.6\u00a0kV/cm and the theoretical energy storage density reaches the maximum value of 9.2\u00a0J/cm 3 .",

The effects of different TiO 2  addition on the phase composition, dielectric and energy storage properties of BKNS glass ceramics were systematically evaluated. With the TiO 2  concentration increasing, a growing content of Ba 2 TiO 4  phase was observed in the glass ceramics. The microstructures appeared to be homogenous and uniform with very low porosity through the addition of TiO 2 , for which the maximal breakdown strength of 2112\u00a0kV/cm and the corresponding energy storage density of 9.48\u00a0J/cm 3  were obtained with x = 7.5. The extremely low dielectric loss of less than 1\u2030 (25\u00a0\u00b0C, 100\u00a0kHz) and the obviously improved microstructure contributed to the increased breakdown strength. In addition, the discharge power density of the glass-ceramic capacitor (x = 7.5) was investigated using the RLC charge-discharge circuit and a relatively high value of 16\u00a0MW/cm 3  at 300\u00a0kV/cm was obtained.",

        "abstract": "Electrostatic capacitors with high power density have been demonstrated as efficient power sources in modern electrical and electronic devices. Nevertheless, the low energy density restricted the applications of electrostatic capacitors in the ever-developing electronic world. To improve energy density, herein, one-dimensional (1D) NaNbO3 (NN) nanowires with a high-aspect-ratio are prepared by a simple hydrothermal method and introduced into a poly(vinylidene fluoride) (PVDF) matrix. The NN@PDA nanowires/PVDF nanocomposite films show a high discharge energy density of 12.26 J cm\u22123 at 410 MV m\u22121, which is about 107% higher than that of pristine PVDF (5.87 J cm\u22123 at 350 MV m\u22121) and 510% higher than that of the best commercial biaxially-oriented-polypropylenes (BOPP) (2 J cm\u22123 at 640 MV m\u22121). Moreover, the composite films show a superior power density of 2.01 MW cm\u22123 and ultra-fast discharge speed of 146 ns. As verified by finite element simulations, 1D NN nanowires incorporation into the polymer matrix could significantly improve the local electric distribution and electric current density distribution in the nanocomposites. Ultimately, it is anticipated that this work will open a new design paradigm to boost the performance of polymer nanocomposites for compact and flexible electrical energy storage applications.",

The effects of phase structures on dielectric properties, electric breakdown strength, energy-storage and charge-discharge performances have been systematically investigated in Na 2 O-BaO-PbO-Nb 2 O 5 -SiO 2 -Al 2 O 3  glass-ceramics. The content of SiO 2  and Nb 2 O 5  affected the dielectric energy storage performances of the glass-ceramics by changing their ferroelectric phase proportions and crystallinity. By XRD analysis and Rietveld refinements, it was found the dielectric constant of the glass-ceramics was positively correlated with the relative proportions of M 2 NaNb 5 O 15  (M = Ba or Pb) and NaNbO 3  phases. The electric breakdown strength was negatively correlated with crystallinity and grain boundary activation energy. The maximum energy storage density 17.9\u202fJ\u202fcm \u22123  was obtained in these glass-ceramics. When the content of Nb 2 O 5  was 30\u202fmol%, under the charge electric field 300\u202fkV\u202fcm \u22121  in overdamped discharge circuit, the instantaneous power density of glass-ceramics capacitors reached 75\u202fMW\u202fcm \u22123 .

The effects of crystallization temperature on dielectric energy storage properties were illustrated by investigating the crystallization kinetics, phase evolution, and microstructure of these glass-ceramics. The crystallization process was mainly affected by the bonding strengths of Si\u2013O and Al\u2013O. When the crystallization temperature increased from 850 to 1000 \u00b0C, crystallinity increased from 64.5 to 97.3%, Ba2NaNb5O15 and NaNbO3 were precipitated in all samples, and microstructural pores and microcracks gradually appeared. All the results showed that these materials were promising candidates for application in pulse capacitors.",

        "abstract": "Inorganic/polymer nanocomposites, using one-dimensional (1D) core\u2013shell structure BaTiO3@Al2O3 nanofibers (BT@Al2O3 nfs) as fillers and poly(vinylidene fluoride) (PVDF) as the polymer matrix, have been prepared. The core\u2013shell structure BT@Al2O3 nfs have been synthesized via coaxial electrospinning. The breakdown strength (Eb) and discharged energy density of the nanocomposites can be significantly improved by creating an insulating Al2O3 shell layer with moderate dielectric constant on the surfaces of BT nanofibers to form a moderate interfacial area. The Al2O3 shell layer could effectively confine the mobility of charge carriers, which reduces energy loss by reducing the Maxwell\u2013Wagner\u2013Sillars (MWS) interfacial polarization and space charge polarization between the fillers and the polymer matrix. As a result, the nanocomposite films filled with 5 vol% BT@Al2O3 nfs exhibit a excellent discharge energy density of 12.18 J cm\u22123 at 400 MV m\u22121, which is \u2248254% over bare PVDF (4.8 J cm\u22123 at 350 MV m\u22121) and \u22481015% greater than the biaxially oriented polypropylenes (BOPP) (\u22481.2 J cm\u22123 at 640 MV m\u22121). The work here indicates that this promising state-of-the-art method of preparing high energy density nanocomposites can be used in the next generation of dielectric capacitors.",

Phase evolution, Crystallization mechanism, dielectric properties, dielectric breakdown strength (DBS), and energy-storage performances were comprehensively studied by varying SiO 2  content. DSC studies revealed simultaneous occurrence of surface and internal crystallization mechanism in the glass-ceramics. XRD results showed three tungsten bronze structure SrNb 2 O 6 , Sr 6 Nb 10 O 30 , NaSr 2 Nb 5 O 15  phases and perovskite structure NaNbO 3  phase, which was quantified by the Reietveld refinement. It was found that dielectric constant and theoretical energy-storage density increased firstly and then decreased with the increase of the SiO 2  contents. For  x \u00a0=\u00a035\u00a0mol%, the theoretical energy-storage density reaches the maximal value of 15.3\u00a0J/cm 3  due to the highest dielectric constant of 124 and DBS of 1669\u00a0kV/cm. And the highest DBS is related to the uniform and dense microstructure for  x \u00a0=\u00a035\u00a0mol%. For practical applications in pulsed RLC circuit, the discharged efficiency increases from 74.2% to 91.5% with the increase of the SiO 2  contents.",

        "abstract": "The effects of a titanium dopant on the phase transition behavior and crystallization mechanism of Ge8Sb92 films were systematically investigated. The crystallization behavior induced by heat was studied by in situ resistance measurements. With the incorporation of titanium atoms, both the crystallization activation energy and electrical resistance increase, resulting in a higher amorphous thermal stability and a lower of the programming energy consumption. A broadening of the optical bandgap causes the enhancement in the amorphous resistance. X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy analysis reveal that a small amount of titanium addition can retard the grain growth and refine the crystal size, owing to the formation of amorphous Ge and Sb components. The shift in the Raman modes associated with Sb upon crystallization was observed. X-ray reflectivity and atomic force microscopy results illustrate that the volume fluctuation becomes smaller and the surface morphology becomes smoother after titanium doping. A reversible phase transition can be achieved by picosecond laser pulses. Phase change memory cells based on a titanium-doped Ge8Sb92 film were also fabricated to evaluate the electrical characteristics. The results indicate that the suitable incorporation of titanium in Ge8Sb92 thin films is an effective way to tune and optimize the crystallization performance for phase change memory applications.",

        "abstract": "Strontium barium niobate-based glass\u2013ceramics (SBN\u2013glass\u2013ceramics) with various B2O3/SiO2 ratios have been prepared by powder-melting method followed by controlled crystallization. The effects of different B2O3/SiO2 ratios on the phase evolution, microstructure, dielectric property, breakdown strength and energy storage density of the SBN\u2013glass\u2013ceramics were studied. In addition, the crystallization kinetics behavior of the SBN\u2013glass was analyzed by differential scanning calorimeter method. The microstructure of the SBN\u2013glass\u2013ceramics by replacing SiO2 with B2O3 becomes dense and uniform dramatically. Through the analysis of the crystallization kinetics, replacing a small amount of SiO2 with B2O3 can make the SBN\u2013glass less stable, which is conducive to crystallization in the SBN\u2013glass. When the ratio of B2O3/SiO2 is 1.5/33.5 in the SBN\u2013glass\u2013ceramics, the dielectric constant is up to 143.2 and the optimized theoretical energy storage density of 7.4 J/cm3 is achieved at room temperature, which is about 2 times higher than that of the boron-free SBN\u2013glass\u2013ceramics.",

        "abstract": "Abstract   A series of Ba 0.4 Sr 0.6 TiO 3 \u2013BaO\u2013B 2 O 3 \u2013Al 2 O 3 \u2013SiO 2  (BST40-BBAS) glass-ceramics with different content of Ba  x  Sr 1\u2212 x  TiO 3  ( x \u00a0=\u00a00.4, 0.7 and 0.9) additives were synthesized by solid state sintering process. The relationships between phase structure, microstructure and dielectric properties were investigated. The XRD results illustrated that all the peaks of BST phases shifted to lower angle with the increasing of Ba  x  Sr 1\u2212 x  TiO 3  additives. Moreover, the shift tendency of peaks became more obvious as the  x  increased. The microstructure results exhibited that an appropriate composition of Ba  x  Sr 1\u2212 x  TiO 3  additives could cut off the contact among the BST glass powders, which effectively restrained the abnormal growth of the BST glass-ceramics. As the Ba  x  Sr 1\u2212 x  TiO 3  additives increased, the dielectric constant of the glass-ceramics increased from 56 to 611 and the Curie temperatures of the BST glass-ceramic specimens moved to high temperature. The breakdown strength (BDS) reduced from 853\u00a0kV/cm to 405\u00a0kV/cm with the increase of BST ceramics concentration. In order to obtain a maximum energy density, the relationship between dielectric breakdown strength and dielectric constant was studied. The glass-ceramic composites synthesized by BST40-BBAS glass-ceramic and Ba  x  Sr 1\u2212 x  TiO 3  ceramics could effectively improve the energy storage density. A maximum of the calculated energy density reached up to 3.1\u00a0J/cm 3 , which was improved by 1.8 times as compared with that of the pure BST40-BBAS glass-ceramic (1.74\u00a0J/cm 3 ).",

The DSC analysis showed that the thermal stability of these as-annealed glasses was increased as the Sr concentration increased. The crystal phases of KSr2Nb5O15 and SrNb2O6 were obtained in the KSN-BAS samples. The microstructure could be modified with the replacement of K by Sr. The correlation between the breakdown strength and the activation energy was studied by the measurement of complex impedance spectra. The dielectric constants of all samples exhibited excellent stability from \u221280 to 120 \u00b0C and dielectric losses below 0.027. When the ratio of Sr/K was 1, a maximum dielectric constant was exhibited about 130.62.

The effects of crystallization temperature on the microstructure, phase evolution and the energy storage behaviors of the novel material were systematically investigated. A maximum theoretical energy storage density of up to 15.3\u2009J/cm 3  was found in the samples heated at 800\u2009\u00b0C. The polarization-electric (PE) hysteresis loops of this material exhibited very good linear character and high energy efficiency. In addition, an approximate value of 25\u2009ns for discharged period T has been obtained, which demonstrated that most of the energy stored in dielectric was released over a very short time. The maximum powder density exceeds a high value of 90\u2009MW/cc in a 390\u2009kV/cm electric field. Therefore, the new developed Bi 2 O 3 -Nb 2 O 5 -SiO 2 -Al 2 O 3  glass-ceramic can be used as an alternative, promising high-performance electrostatic capacitor material.",

More importantly, the nanocomposite films loaded with 5 vol% ST@AO NFs show an outstanding discharge energy density of 15.3 J cm\u22123 at 475 MV m\u22121 and maintain a high discharge efficiency of 68.52%.

        "abstract": "Abstract   In this work, the (0.94-x)(Na 0.5 Bi 0.5 )TiO 3 -0.06Ba(Zr 0.05 Ti 0.95 )O 3 -x(Sr 0.8 Bi 0.1 \u25a1 0.1 )TiO 2.95  (NBT-BZT-xSBT) ternary relaxor ferroelectrics were chosen as the studied compositions, and the  in - situ  electric-field-dependent Raman spectra and PFM measurements were performed to systematically investigate the structural distortion and local polarization switching. Results showed that the SBT enhances the relaxor degree and depresses the field-induced local distortion. The higher field required initially for obtaining polarization saturation with increasing SBT concentration is related to overcoming the hindrance posed by the local structural heterogeneity. Most intriguingly, a giant and temperature-insensitive electrostrictive effect ( Q  33 \u202f=\u202f0.035 m 4 /C 2 , RT\u223c120\u202f\u00b0C: variation less than 2%) was achieved in SBT5 composition. Such performance is one of the best values ever reported on lead-free and lead-based electrostrictive materials. A modified Landau model was proposed to phenomenologically elaborate the underlying mechanisms. Our findings illustrate that understanding structural changes at multiple length scale will be helpful for designing novel lead-free piezoceramics with high performance.",

Herein, we report a large d33* value of 640 pm V\u22121 and a low degree of strain hysteresis of 33% in a novel (0.67 \u2212 x)BiFeO3\u20130.33BaTiO3\u2013x(Ba0.8Ca0.2)ZrO3 system with x = 2 mol% (BCZ2). A large and linear electrostrictive property (Q33 = 0.029 m4 C\u22122) was achieved in the BCZ6 composition. Furthermore, the strain and electrostrictive properties present a robust thermal stability. The salient strain performance of BCZ2 can be explained by a reversible field-induced relaxor-ferroelectric phase transition, while the low strain hysteresis is due to a rapid response of forward and backward switching between relaxor and ferroelectric phases facilitated by the weak nonergodicity. The origin of the superior physical properties was systematically elucidated from the micro- and macroscopic views. Our work suggests that the strategy of engineering relaxor dynamics promises to boost the actuating performances, which may pave the way towards exploiting BiFeO3-based incipient piezoceramics in high-precision sensor and actuator applications.",

        "abstract": "High-performance (Na0.5Bi0.5)TiO3 (NBT) lead-free incipient ceramics are promising piezoactuator materials, but high driving fields to deliver the large strain limits their practical applications. Herein, we report a giant piezoelectric strain (d33*) of 810 pm V\u22121 at a low driving field of 4 kV mm\u22121 in a novel ternary (0.94 \u2212 x)(Na0.5Bi0.5)TiO3\u20130.06Ba(Zr0.05Ti0.95)O3\u2212x(Sr0.8Bi0.1\u25a10.1)TiO2.95 solid solution with x = 0.05 (SBT5). The field of SBT5 critical composition is notably reduced compared with other NBT-based ceramics, while its strain properties are maintained at a high level along with an excellent thermal stability. The dopant induces a randomly distributed local polarization field, which breaks the symmetry of Landau potential curves, boosts the ferroelectric instability and favors a more disordered relaxor structure. The giant strain in the critical composition SBT5 is due to a field-induced reversible relaxor-ferroelectric phase transformation, while the reduced driving field results from two synergistic effects: remanent quasi-ferroelectric order as the seed for the growth of polar domains helps the system skip the nucleation process; the local defects further facilitate the growth of ferroelectric domains. The composition, temperature and electric-field dependence of structural evolutions were systematically elucidated from the micro- and macroscopic view. This study opens up a feasible and effective way for achieving giant electrostrain in lead-free actuator materials.",

A dense microstructure and fine grain size was obtained with addition of BNIZ content. The dielectric behaviors indicated the dominance of ergodic relaxor phase. The 0.9BT-0.1BNIZ ceramic was found to possess an enhanced recoverable energy density (W R \u223c1.33\u202fJ/cm 3 ) and efficiency (\u03b7\u223c88%) under 18\u202fkV/mm at room temperature.

The high stability of energy storage properties is mainly ascribed to the characteristics of ergodic relaxor phase. The stored energy was released in sub-microseconds (\u223c0.19\u202f\u03bcs). The superior current density (C D \u223c796\u202fA/cm 2 ) and the power density (P D \u223c39.8\u202fMW/cm 3 ) were obtained simultaneously. The enhanced W R  and the superior charge-discharge performances strongly demonstrate that the BT-based ceramics are promising candidates of high-power pulse capacitor applications.",

        "abstract": "The electrocaloric effect (ECE) in lead-free relaxor ferroelectrics has gained significant interest over the past decades. However, certain aspects of the ECE in relaxor ferroelectrics, such as Bi0.5Na0.5TiO3, remain poorly understood. In this work, we investigate the ECE by considering Bi0.5Na0.5TiO3-SrTiO3 (BNT-ST) as an example. The results show that, for BNT-0.25ST ceramics, the directly-measured ECE is optimal when the freezing temperature is tailored to be about room temperature. For this material, \u0394T\u2009=\u20090.51\u2009K under an electric field of 6\u2009kV/mm and the ECE has excellent thermal stability (the instability \u03b7\u2009\u2264\u200920% in the range 30\u2013120\u2009\u00b0C). The addition of strontium increases the cubic-phase fraction, enhances the local random field, and changes the local structure, as clarified by in situ Raman spectroscopy and piezoelectric force morphology. In addition, we discuss in detail the correlation between the ECE and local structure. This work thus improves our understanding of the ECE in BNT-based materials...",

The excellent performance is owning to the increase of breakdown strength (BDS) value and the intrinsic mechanism for enhanced BDS value by MgO incorporation is disclosed by numerical simulations (COMSOL). Moreover, the studied composite exhibits excellent charge-discharge performance, the current density ( C D  ) and power density ( P D  ) are 1671 A/cm 2  and 150\u2009MW/cm 3 , respectively, which are much superior to that of other ceramics. Besides, most of the stored energy is discharged within \u02dc0.15 \u03bcs via charge-discharge tests. This work not only provides a novel technique to designing bismuth-based ceramic capacitors with simultaneously high  W d  ,  \u03b7  and excellent charge-discharge performance, but also deepens the understandings of the role for the metallic oxide in the composite.",

        "abstract": "In this work, the structure of end-member Bi(Me0.5Ti0.5)O3 (Me = Zn, Ni, Mg, Co) was calculated through a first-principles method and lead-free piezoelectric ternary systems (0.94 -x)(Bi0.5Na0.5)TiO3-0.06BaTiO3-xBi(Me0.5Ti0.5)O3 (Me = Zn, Ni, Mg, Co) (BNT-BT-Bi(Me0.5Ti0.5)O3) were designed to achieve a large strain response for actuator applications. Composition-driven phase transition characteristics and the resulting associated piezoelectric and electromechanical properties were systematically investigated, and schematic phase diagrams were constructed. XRD measurements, Raman spectra analysis and temperature-dependent polarization and strain hysteresis loops indicate that Bi(Me0.5Ti0.5)O3 substitution induces a phase transformation from a ferroelectric rhombohedral to an ergodic relaxor pseudo-cubic phase, accounting for the large strain response (>0.3%) with a high normalized strain Smax/Emax (\u2265550 pm V(-1)) at around the corresponding critical composition in the vicinity of room temperature. In addition, correlations between the tolerance factor t of the added end-member, the calculated tetragonality and the morphotropic phase boundary (MPB) composition were sought. In comparison to other reported BNT-based systems, there is a noticeable correlation between the MPB composition and the calculated tetragonality of the end-member Bi(Me0.5Ti0.5)O3, and the t value corresponding to the formation of the MPB composition is approximately 0.981 in the present ternary system with low tolerance factor end-members. As a result, we believe that the general correlations and design principles obtained from the present comprehensive research will be effective to predict the approximate MPB region quickly in BNT-based ceramics with an excellent actuating performance.

        "abstract": "Pb-based piezoelectric materials such as PZTs have been the mainstay for electromechanical devices, however encounter the challenge of sustainable environmental development, which require the Pb-free piezoelectric counterparts. The foremost obstacles in developing Pb-free piezoceramics are their low piezoresponse and inferior temperature stability. In this work, we reported Mn-modified <00l>c-textured (K,Na)NbO3 based ceramics to achieve thermally stable piezoelectric properties and enhanced fatigue resistance in conjunction with high piezoelectricity of d33~560 pC/N. The in situ d33 measurement reveals that the temperature stability of the small signal d33 is mainly depended on the temperature induced phase transition. While the local PFM measurements imply that the excellent temperature stability of the large signal d33* (field-induced strain) benefits from the stable domain response to applied electric field at elevated temperatures. Moreover, the good fatigue resistance is proposed to be associated with the decreased defect concentration by Mn doping, based on the analyses of dielectric loss, leakage current and thermally simulated depolarization current.",

The phase boundaries including orthorhombic-tetragonal (O-T) and rhombohedral-tetragonal (R-T) multiphase coexistence were identified by XRD patterns and temperature-dependent dielectric constant by adding different content of BNKZ.

        "abstract": "Abstract   To attain a deep understanding of piezoelectric and dielectric properties dependence of crystallographic orientation, the rhombohedral 0.90(Bi 0.5 Na 0.5 )TiO 3 -0.10(Bi 0.5 K 0.5 )TiO 3  (abbreviated as BNT-BKT) single-crystal films with three primary orientations of (100), (110), (111) were obtained by sol-gel method. Crystallographic structure measurement by X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) revealed that the BNT-BKT films display a pure perovskite phase and a good epitaxial relationship. Crystallographic orientation dependence of piezoelectric and dielectric properties of the BNT-BKT thin films was investigated. The superior piezoelectric properties in (100)-oriented epitaxial thin films are mainly derived from the intrinsic piezoelectric activities based on the crystallographic orientation and corresponding ferroelectric domain structure analysis. It is also important to note that the Curie temperature ( T  c ) and dielectric permittivity in piezoelectric films were also affected by the crystallographic orientation.",

The effects of Bi 4 Ti 3 O 12  dopant on the strain behavior, dielectric, ferroelectric and piezoelectric performance of BNT-BT ceramics were systematically investigated. A optimal strain value of ~0.37% was achieved around the critical composition of x=6 wt% which corresponds to a normalized strain ( S  max / E  max ) of 465\u00a0pm/V. The large strain response in this sample is mainly originated from two aspects: one is that BiT addition induced ferroelectric-to-relaxor phase transition evidenced by \u201cpinched\u201d ferroelectric hysteresis loops and vanished negative strain of bipolar strain loops as well as downward shift of  T  F-R ; the other is that the small-sized nanodomains (or polar nanoregions) facilitate the domain switching and domain wall motion with an applied electric field, which lead to large external contribution to strain response. These results indicate that BNT-BT-xBiT piezoelectric ceramics with large strain response may be a promising lead-free material for actuator application.",

The NKBNT ceramics possess the local structure with the coexisted rhombohedral  R 3 c  and tetragonal  P 4 bm  polar-nano-regions (PNRs). The  R 3 c  and  P 4 bm  PNRs coexist in a wide temperature range, then the local structure transforms to the  P 4 bm  PNRs around the temperature of dielectric maximum ( T  m ) evidenced by the doublet splitting of Ti-O modes (peak  B ) and oxygen octahedral vibrational modes (peak  C ). The discontinuous changes of wavenumber and line-width of peak  B  2  and peak  C  3  as well as the dielectric local maxima around the rhombohedral-tetragonal phase transition temperature ( T  RT ) are considered to result from the thermal evolution of  R 3 c  and  P 4 bm  PNRs. The macroscopic changes of non-polar phase with electric field and temperature were investigated by the temperature-dependent polarization-electric field ( P - E ) loops, current-electric field ( I - E ) loops and bipolar strain ( S - E ) curves. The electric-field level necessary to form the long-range ferroelectric order from non-polar phase associated with the stability of the induced ferroelectric phase depends strongly on the temperature.",

The composition-induced structural transitions were investigated by Raman spectra, dielectric analyses, and electrical measurements. It is found that the relaxor phase can be induced through the modulation of the (Na, K) content. The (Na, K) deficiency in BNKST(0.5-x) ceramics favors a more disordered local structure and can result in the loss of long-range ferroelectricity. The x=0.015 critical composition possesses relatively high positive strain Spos of 0.42% and large signal piezoelectric constant d33* of 479 pm V\u22121 at 6 kV mm\u22121, along with the good temperature (25-120\u00b0C) and frequency (1-20 Hz) stability. The recoverable large strain responses in nonstoichiometric ceramics can be attributed to the reversible relaxor-ferroelectric phase transition, which is closely related to the complex defects (VNa\u2032, VK\u2032, and VO..) and the local random fields. This work may be helpful for the exploration of high-performance NBT-based lead-free materials by means of A-site compositional modification.",

        "abstract": "Abstract   Low-lead-content (1-x)(Bi 0.5 Na 0.5 )TiO 3 -xPbTiO 3  (x\u00a0=\u00a00, 0.05, 0.10, 0.15, 0.25) (hereafter abbreviated as BNT-xPT) thin films were prepared by a sol-gel method, and their crystal structure, dielectric properties, recoverable energy-storage density and piezoelectric response were investigated as a function of PT concentration. Combining the XRD patterns and Raman spectroscopy indicate the phase structures go through rhombohedral (R) \u2013 rhombohedral\u00a0+\u00a0tetragonal (R\u00a0+\u00a0T) \u2013 tetragonal (T) evolution with increasing of PT content. A high recoverable energy storage density of 13.02\u00a0\u00b1\u00a00.39\u00a0J/cm 3  was achieved in the BNT-0.10PT thin films due to the high field endurance and significantly enhanced polarizability. Moreover, a superior piezoelectric response ( d  33  * \u00a0=\u00a0120\u00a0\u00b1\u00a05\u00a0pm/V) was also obtained in the 10% PT-modified BNT films, which can be attributed to easy polarization rotation due to low polarization anisotropy on the R-T phase boundary. These properties indicate that BNT-0.10PT films might be promising multifunctional materials for piezoelectric micro-actuator and energy storage embedded capacitor applications.",

        "title": "Tuning the ferroelectric-relaxor transition temperature in NBT-based lead-free ceramics by Bi nonstoichiometry",
        "abstract": "Abstract   In this study, the Bi-nonstoichiometric 0.99Bi x (Na 0.8 K 0.2 ) 0.5 TiO 3 -0.01SrTiO 3  (BNKST) ceramics with x\u00a0=\u00a00.5\u20130.535\u00a0mol (Bi50-Bi53.5) were prepared by a conventional solid-state reaction method. The effects of Bi excess on structural transition and ferroelectric stability of BNKST ceramics were systematically investigated by the Raman spectra, dielectric analyses and electromechanical measurements. The introduction of excess Bi 3+  could significantly break the long-range ferroelectric order and favor the presence of relaxor phase, then the ferroelectric-relaxor transition temperature ( T  FR ) can be effectively tuned to around room temperature by Bi nonstoichiometry, giving rise to an enhanced room-temperature strain property. The positive strain  S  pos  and dynamic piezoelectric constant  d  33  *  of Bi52.5 critical composition reach 0.33% and 440 pm/V, respectively at 6\u00a0kV/mm. The high recoverable strain of Bi52.5 sample can be attributed to the electric-field-induced reversible relaxor-ferroelectric phase transition. The present work may be helpful for further understanding and designing high-performance NBT-based lead-free ceramics for piezoelectric actuator applications.",
