"abstract": "Objective The present study was designed to understand the initial vaccination rate of the neonatal anti-hepatitis B vaccine, the whole range vaccination rate and the infection rate of maternal hepatitis B virus in Wuhan city. Methods Delivery rooms of all hospitals and planned immunization sites in the city were investigated and statistically analyzed using Microsoft Excel 2000. Results The initial immunization rate of the neonatal hepatitis B vaccine was 98.51% , with a timely rate of 95.32%. The urban areas were better than the suburbs in the aspects. The rate of full-course immunization was 86.87%, the suburbs better than the urban areas, and permanent population better than floating population. The screening rate of hepatitis B of postnatal women in the whole city was 66.29 and the carrier rate 6.04%. The anti-hepatitis B immunoglobulin rate of the neonatals whose mothers carried HBV was 84.24%. And the urban areas was better than the suburbs in hepatitis B screening and the neonatal anti-hepatitis B immunoglobulin immunization. Conclusion The initial immunization rate and the timely rate have been encouraging since the implementation of free immunization of neonatal hepatitis B vaccine in the whole city, but the full-course rate is less satisfying. There exists a weakness in the planned immunization, and particularly the difficulty in the management of floating population in the urban areas interferes with planned immunization substantially. The immunization of hepatitis B vaccine in adolescent should be covered in the immunization programme.",

"abstract": "To improve the quality of life (QOL) of patients with nasopharyngeal carcinoma (NPC) after chemoradiotherapy (CRT), it is necessary to find an effective method to reduce the toxic side-effects of CRT.Between June 2007 and June 2010, 83 previously untreated patients with NPC were randomized to receive CRT either with or without non-invasive extracorporeal radiofrequency (ERF). All the patients underwent radiation, and weekly chemotherapy of paclitaxel 135-175 mg/m(2) and cisplatin 60-90 mg/m(2). In addition, the patients in the treatment group also underwent non-invasive ERF on a radiofrequency machine at 13.56 MHz for 1 hour at 41-43°C. After the completion of treatment, evaluation was carried out to determine the survival rate, disease-free survival time, and QOL. QOL was analyzed by using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Cancer Module (EORTC QLQ-H&N35) every 6 months during the three-year period.After completion of the treatments, the 36-month survival rate was 0.730 in the treatment group and 0.535 in the reference group (p = 0.041); the average disease-free survival time was 48 months in the treatment group and only 37.5 months in the reference group (p = 0.048). In the post- treatment questionnaires, several NPC-specific (pain, swallowing, speech, social eating, opening mouth, dry mouth, sticky saliva) QOL domains were better preserved with CRT + ERF compared to CRT at different time-points.The combination treatment of ERF with CRT can prolong the survival rate and disease-free survival time and improve the QOL for patients with NPC.",

"abstract": "To observe the anti-virus effects of andrographolide (AD) on the retinoic acid-inducible gene-I (RIG-I)-like receptors (RLRs) signaling pathway when immunological cells were infected with H1N1.Leukomonocyte was obtained from umbilical cord blood by Ficoll density gradient centrifugation, and immunological cells were harvested after cytokines stimulation. Virus infected cell model was established by H1N1 co-cultured with normal human bronchial epithelial cell line (16HBE). The optimal concentration of AD was defined by methyl-thiazolyl-tetrazolium (MTT) assay. After the virus infected cell model was established, AD was added into the medium as a treatment intervention. After 24-h co-culture, cell supernatant was collected for interferon gamma (IFN-γ) and interleukin-4 (IL-4) enzyme-linked immunosorbent assay (ELISA) detection while immunological cells for real-time polymerase chain reaction (RT-PCR).The optimal concentration of AD for anti-virus effect was 250 μg/mL. IL-4 and IFN-γ in the supernatant and mRNA levels in RLRs pathway increased when cells was infected by virus, RIG-I, IFN-β promoter stimulator-1 (IPS-1), interferon regulatory factor (IRF)-7, IRF-3 and nuclear transcription factor κB (NF-κB) mRNA levels increased significantly (P<0.05). When AD was added into co-culture medium, the levels of IL-4 and IFN-γ were lower than those in the non-interference groups and the mRNA expression levels decreased, RIG-I, IPS-1, IRF-7, IRF-3 and NF-κB decreased significantly in each group with significant statistic differences (P<0.05).The RLRs mediated viral recognition provided a potential molecular target for acute viral infections and andrographolide could ameliorate H1N1 virus-induced cell mortality. And the antiviral effects might be related to its inhibition of viral-induced activation of the RLRs signaling pathway.",

"abstract": "AIM:To observe the pathologic changes of cardiomyopathy in type 2 diabetic rats and the therapeutic effect of Xuefuzhuyu decoction.METHODS: The diabetic model was established by feeding the animals with high-fat diet and injecting a middle dose of streptozotocin (50 mg/kg) intraperitoneally in 42 Wistar male rats. After 8 weeks,the damage of the heart in the model animals was detected by electrocardiogram and echocardiography,and the serum level of glucose,total cholesterol and triglyceride were determined by the methods of clinical chemistry. The content of collagen was quantified by Masson staining. The apoptosis of cardiomyocytes was measured by TUNEL apoptosis kit. The structures of myocardial damage were observed under light and electronic microscopes.RESULTS: (1) Compared with normal group at the same time points,the contents of serum glucose,triglyceride and cholesterol in model group increased (P<0.05). At the 11th and 14th weeks,the thickness of LVDS was significantly increased (P<0.01),the structure of myocardial tissues was severely damaged and collagen fiber content increased obviously (P<0.01). The cell apoptosis was also increased. (2) Compared with control group at the same time points,the contents of serum glucose,cholesterol and triglyceride in Xuefuzhuyu decoction group significantly decreased (P<0.05). The thickness of LVDS at the 11th and 14th weeks was decreased (P<0.05) and LVM at the 14th week became significantly thinner (P<0.01). The damage of the myocardium and subcellular structure was slighter and the content of collagen was lower than that in control group (P<0.05). The cell apoptosis was also attenuated.CONCLUSION: The levels of blood glucose,total cholesterol and triglyceride and the content of collagen fibers increase when diabetic cardiomyopathy develops,with more cell apoptosis and severe damage in the cardiac structure. Xuefuzhuyu decoction decreases the level of blood lipid in diabetic cardiomyopathy,alleviates the pathological changes of myocardial fibrosis and delays the progression of diabetic cardiomyopathy.",

"abstract": "To observe the effect of electroacupuncture (EA) combined with gavage of borneol on the permeability and ultrastructure of the blood-brain barrier (BBB) in mice, so as to reveal its mechanism underlying improving permeability of BBB.For assaying Evans blue (EB) content in the brain, 60 Kunming mice were evenly divided into control, EA, borneol (0.2 g/kg, borneol-0.2), borneol (0.4 g/kg, borneol-0.4), borneol (0.2 g/kg, borneol-0.2) + EA and borneol (0.4 g/kg, borneol-0.4) + EA groups. For determination of P-glycoprotein [P-gp, a member of the superfamily of ATP-binding cassette (ABC) transporters which transport various molecules across extra- and intra-cellular membranes] function and the ultrastructure of BBB, other 84 mice were randomized into control, borneol-0.2, borneol-0.4, borneol-0.2 + EA, borneol-0.4 + EA and verapamil groups (n=10 for P-gp. function analysis, and n 2 for electron microscopic observation). EA (2 Hz, 1 mA) was applied to \"Baihui\" (GV 20) and \"Yamen\"(GV 15) for 20 ml once daily for 14 days. EB (2.5%, 0.2 mL/kg) and rhodamine (Rh) 123 (0.2 mg/kg) were injected intravenously first through the tail vein, and their contents in the brain and Rh 123 in the plasma were detected after EA by using an ultraviolet fluorescence microplate reader. At the same time, the permeation index (Kp) was calculated by the ratio of Rh 123brain/Rh 123blood.Compared with the control group, the cerebral EB and Rh 123 contents and Kp of BBB in the EA, borneol-0.2, borneol-0.4, borneol-0.2 + EA, borneol-0.4 + EA and verapamil groups were increased significantly (P < 0.05, P < 0.01). The cerebral EB content was significantly higher in the borneol-0.2 + EA group than in the borneol-0.2 group (P < 0.05), suggesting a synergistic effect of EA and borneol. No significant differences were found among the EA, borneol-0.2 and borneol-0.4 groups in cerebral EB levels, among the control, EA, borneol-0.2, borneol-0.4, borneol-0.2 + EA, borneol-0.4 + EA and verapamil groups in plasma Rh 123 contents, and among the EA, borneol-0.2, borneol-0.4, borneol-0.2 + EA, borneol-0.4 + EA and verapamil groups in cerebral Rh 123 contents and Kp of BBB (P > 0.05). Results of the electron transmission microscope showed that the compact degree of the tight junction of BBB was decreased in the borneol-0.2, borneol-0.4, borneol-0.2 + EA, borneol-0.4 + EA groups but not in the EA group.EA and gavage of borneol treatments may enhance the permeability of BBB for EB and Rh 123 and have a certain synergistic effect in mice. The effect of borneol may be closely with the inhibition of P-glycoprotein and the decrease of tight junction of BBB while the effect of EA treatment is probably related to the inhibition of P-glycoprotein only.",

"abstract": "To observe the effects of Rubiae Radix et Rhizoma (RRR) and carbonized Rubiae Radix et Rhizoma (CRRR) on the acute blood stasis rat model, and reveal their differences in efficacy.The acute blood stasis model was induced by subcutaneously injecting adrenaline hydrochloride and soaking in ice water. Yunnan Baiyao was used as the positive control drug, and administered for consecutively seven days. This model was adopted to observe the effect of high, middle and low dose RRR and CRRR groups on hemorheology, thrombin activity, and blood platelet system.RRR could significantly reduce the wholeblood viscosity and plasma viscosity of blood stasis rats under different shear rates, and showed certain two-way regulating function in hemostasis. It also showed certain effect on ADP-induced platelet aggregation rate, but which was lower than CRRR. CRRR achieved the main hemostatic mechanism by stimulating intrinsic and extrinsic blood coagulation and fibrinogen, and could significantly enhance the platelet aggregation rate of rats in the acute blood stasis model (P <0. 01).RRR had the effect of removing blood stasis and hemostasis, while CRRR mainly has the hemostatic effect. This further demonstrates the traditional processing theory of \"promoting blood circulation with crude herbs and stopping bleeding with processed herbs\".",

Yunnan Baiyao was taken as the positive control drug, and PCC decoctions (5.0, 10.0 g x kg(-1)) were given simultaneously, in order to detect changes in general physical signs of rats, such as body weight, daily diet, volume of daily drinking and urine and stool, and rectal temperature. Automatic hematology analyzers was used to determine white blood cell (WBC), red blood cell (RBC), hemoglobin (HGB), and hematocrit (HCT), blood time by docking (BT). Blood rheometers was used to detect whole blood and plasma viscosities, thrombin time (TT), activated partial thromboplastin time (APTT), prothrombin time (PT) and fibrinogen content (FIB). Indexes related to thyroid functions, such as triiodothyronine (T3), tetraiodothyronine (T4), reverse triiodothyronine (rT3) and thyroid stimulating hormone (TSH) were measured by radio-immunoassay, and changes in lung tissues were observed by hematoxylin-eosin (HE) stain.After modeling, rats witnessed slow-down in weight growth rate, significant increase in daily diet, volume of daily drinking, urine and temperature, significant decrease in stools and their water content (P < 0.05, P < 0.01), rise in plasma T4 level, notable growth in T3 and rT3 concentrations (P < 0.05), decline in TSH concentration. Additionally, their WBC, RBC, HGB and HCT remarkably increased (P < 0.05, P < 0.01), with significant increase in high, middle and low whole blood viscosities and plasma viscosity (P < 0.01); their BT, TT, APTT were notably prolonged (P < 0.01), with significant increase in FIB content (P < 0.01). After oral administration of Yunnan Baiyao or PCC, rats of all groups showed significant improvement in blood heat syndromes (P < 0.05, P < 0.01), and their blood coagulation indexes including BT, TT, APTT, FIB, thyroid function indexes including T4, T3, rT3, TSH, WBC, RBC, HGB, HCT, whole blood viscosity and plasma viscosity were getting normal (P < 0.05, P < 0.01).PCC can ameliorate blood heat symptoms and pathologic hemorrhage among rats with blood heat and hemorrhage syndromes by inhibiting thyroid functions and correcting hemorheological and coagulation disorders.",

Depression model was established by lonely raising and chronic unpredictable mild stress (tail cramping, water-deprivation, fasting, electrical shock stimulation, etc. ) for 21 days. EA (2 Hz, 1 mA) was applied to \"Baihui\"(GV 20) and \"Yamen\"(GV 15) for 20 min, once daily for 14 days. Changes of ethology including glucose-consumption during 1 h, crossing and rearing scores of open-field test during 3 min (for assessing the rats' locomoto)and laser Doppler flowmetry values of cortical regional cerebral bloodflow (r CBF) were detected, and Morris water maze test (for assessing the rats' learning-memory ability) was conducted.In comparison with the control group, the sucrose consumption, crossing and rearing scores of open-field test, the average swimming velocity (ASV). the ratios of path length and swimming duration near the hidden-platform and the path length and swimming duration far from the platform of Morris water maze test during 70 seconds, and the cortical r CBF value in the model group were decreased significantly (P < 0.01), while the total swimming distance and escape latency in the model group increased apparently (P < 0.01). Compared to the model group, the average sucrose consumption, crossing and rearing scores of open-field test, the ASV, and the ratios of path length and swimming duration near the platform and those far from the platform in the lower-dose. lower-dose + EA, higher-dose and higher-dose + EA groups, and the cortical r CBF in the lower-dose + EA and higher-dose + EA groups were increased considerably (P < 0.05, P < 0.01). The total swimming distances and escape latencies of lower-dose, lower-dose + EA, higher-dose and higher-dose + EA groups were significantly shortened in comparison with the model group (P < 0.05, P < 0.01). The sucrose consumption and crossing score were significantly higher in the higher-dose + EA group than the lower-dose group (P < 0.05). The escape latency was significantly shorter in the higher-dose + EA group than in the lower-dose group (P < 0.05). No significant differences were found among the lower-dose, lower-dose + EA and higher-dose groups the sucrose consumption, crossing score and escape latency: among the lower-dose, lower-dose + EA, higher-dose and higher-dose + EA groups in the rearing score and ASV; among the lower-dose, higher-dose and model groups in the cortical r CBF (P > 0.05).EA can enhance the effect of extract of HP-L in increasing sucrose consumption, crossing score and cerebral blood flow, and in shortening escape latency in depression rats, which may contribute to their effect in improving depression. But HP-L itself has no effect on cortical microcirculation.",

"abstract": "The current study was designed to explore the mechanism of the prokinetic activity of Gentiopicroside (Ge), from Gentiana macrophylla Pall which is widely used to strengthen gastric motility in clinic.Gastrointestinal motility disorder rats were induced by stress stimulation and the rats were treated with Ge. The functions of gastric emptying and intestinal propelling were measured after blood was obtained to assay the levels of plasmatic motilin (MTL), vasoactive intestinal peptide (VIP), somatostatin (SST), gastrin (GAS), neurotensin (NT) and substance of P (SP). The expressions of MTL receptor (MTLR), VIP receptor 2 (VIPR2) and SST receptor 2 (SSTR2) were measured also. In addition, an isolated guinea pig ileum was applied to evaluate the influences of Ge on M-R, H1-R, 5-HT4-R and D-R in vitro.Ge increased gastric emptying and intestinal propelling obviously. It also decreased the level of SST and increased GAS in plasma significantly. Moreover, it promoted the expressions of MTLR in gastric antrum, duodenum, jejunum and ileum, and restrained the expression of VIPR2 in duodenum. Piboserod and loratadine had no obvious restrain to Ge' exciting ileum effect and Ge also didn't affect dopamine paralyzing ileum. However, Ge failed to improve the hypofunction of guinea pigs ileums pre-treated with atropine sulfate.The mechanisms of Ge' prokinetic effect were associated with modulating the levels of SST and GAS in plasma, raising the expressions of MTLR in gastric antrum, duodenum, ileum and jejunum, reducing the expression of VIPR2 in duodenum and activating M-R.",

"abstract": "Objective:To investigate the effects of Radix Pseudostellariae on cardiac remodeling of chronic heart failure induced by acute cardiac infarction after coronary artery ligation and its mechanism. Methods:Rat chronic heart failure was produced by coronary artery ligation of 6 weeks. The cardiac remodeling was evaluated with remodeling indexes such as left and right ventricular indexes,lung index,and globular index,etc. The death ratio of model rats was used to indicate the heart failure degree. Cytokine of IL-2 and TNF-α were detected by ELISA to explore the mechanism of Radix Pseudostellariae. Results:During the process of heart failure caused by coronary artery ligation and the heart muscle remodeling,the death rate of model rats was 43.8%,heart and lung indexes,heart remodeling index and serum levels of IL-6 and TNF-α were significantly higher in modeling group than those of sham operation group. After the treatment of Radix Pseudostellariae decoction by ig for continuous 5 weeks,the death rate,cardiac remodeling indexes,and serum levels of IL-6 and TNF-α markedly decreased. Conclusion:Long-term use of Radix Pseudostellariae can ameliorate cardiac remodeling of the chronic heart failure induced by acute cardiac infarction and the one of the mechanisms might be its influence to cytokine.",

"abstract": "Borneol is widely used in traditional Chinese medicine to facilitate the distribution of central nervous system (CNS) drugs in brain due to its ability to open blood-brain barrier (BBB), however, the underlying mechanism is still unclear. In this study, the effect of borneol on different brain regions were investigated to explore the mechanism.After oral administration of borneol (0.1, 0.2g/kg) for seven consecutive days, SD rats were injected with Rh123 (1.0mg/kg). The concentrations of Rh123 were detected in four brain regions of cortex, hippocampus, hypothalamus and striatum by a small animal vivo imaging system and a fluorescence microplate reader respectively. The ultrastructures of BBB were examined. Moreover, the expressions of the four transporters of ATP-binding cassette (ABC) family, multidrug resistance 1a (Mdr1a), multidrug resistance 1b (Mdr1b), multidrug resistance protein 1 (Mrp1), Mrp4, Mrp5 and breast cancer resistance protein (Bcrp) in the four brain regions were analyzed. Finally, the deliveries of borneol in the plasma and the four brain regions were examined by a pharmacokinetics study.Administration of 0.2g/kg borneol produced loose structure in the tight junction and void structure between the endothelial cell and mesangial cell. Borneol at 0.1g/kg and 0.2g/kg increased the delivery of Rh123 in hippocampus and hypothalamus obviously. Permeability index followed a similar trend. Protein expression assays showed that borneol decreased the expression of Mdr1 and Mrp1 in hippocampus and hypothalamus. Further RT-PCR study showed that borneol decreased the expressions of both Mdr1a and Mdr1b in hippocampus and hypothalamus. The pharmacokinetics study demonstrated that the delivery of borneol in cortex was the most and that in striatum the least, with the deliveries of borneol in hippocampus and hypothalamus in between.Borneol showed tissue specific BBB-opening effect, which was associated with its regulation of the ultrastructure of brain tissues and the expressions of Mdr1a, Mdr1b and Mrp1. The present study indicated that borneol should be used in concert with drugs targeting hippocampus or hypothalamus to exert its synergistic effect to the maximum.",

"abstract": "Our previous studies have shown that cyclovirobuxine D (CVB-D) ameliorated the cardiac function in heart failure rats. Considering the relationship between cardiac function and [Ca(2+)]i, and the role of calcium cycling on regulating [Ca(2+)]i, the present study was designed to evaluate the influence of CVB-D on the calcium transient of myocytes from neonatal rats and adult heart failure (HF) rats. The expression of calcium cycling proteins, including L-type calcium channel (LTCC), ryanodine receptor 2 (RYR2), sarcoplasmic reticulum calcium ATPase 2a (SERCA2a) and sodium-calcium exchanger (NCX), were investigated to explore the underlying mechanism. CVB-D increased the intensity of calcium transient, accelerated the process of calcium transient and attenuation in the neonatal and adult myocytes. Furthermore, CVB-D shortened T(peak) and T(attenuation) in the adult myocytes and slowed down the heart rate of neonatal myocytes. Besides, CVB-D increased the expression of RYR2 and SERCA2a, decreased the expression of NCX, but showed no significant effect on LTCC. Thus, it was concluded that CVB-D increased the release and uptake of Ca(2+) in systolic and diastolic period, respectively. CVB-D might not only facilitate the utilization of intracellular Ca(2+), but also prevent the loss of Ca(2+).",

The depression model was established by chronic unpredictable mild stress. EA (2 Hz, 1 mA) was applied to \"Baihui\"(GV 20) and \"Yamen\"(GV 15) for 20 min, once daily for 14 days. The expression levels of multidrug resistance (Mdr) 1a, Mdr 1b, multidrug resistance-associated protein (Mrp) 1, Mrp 4, Mrp 5, and breast cancer resistance protein (Bcrp) gene and proteins in the cerebral cortex tissue were detected by RT-PCR semi-quantitative analysis and Western blot, respectively.In comparison with the control group, no obvious changes were found in the expression levels of cerebral Mdr la, Mdr 1b, Mrp 1, Mrp 4, Mrp 5 and Bcrp genes and proteins in the model group (P > 0.05), and only cerebral Mdr 1a gene and protein expression levels in the EA group were evidently down-regulated (P < 0.01, P < 0.05). Compared with the model group, only cerebral Mdr la gene and protein expression levels were obviously decreased in the depression+ EA group (P < 0.01, P < 0.05). No significant changes were found in the Mdr 1b, Mrp 1, Mrp 4, Mrp 5 and Bcrp genes and proteins after EA intervention in depression rats (P > 0.05).EA of GV 20 and GV 15 can obviously down-regulate the expression of cerebral Mdr 1a in depression rats which might be involved in the opening activity of blood-brain barrier.",

"abstract": "Objective: To probe the effect of urinary LH on deciding the best time for intrauterine insemination(IUI) in induced ovulation.Methods: According to leading follicular size or according to both leading follicular size and the character of urinary LH to decide the different timing of IUI,the relationship between pregnancy rate and the timing of IUI as well as the cause of different pregnancy rate were analyzed. Results: There were 54 pregnancy cases in 227 cycles of 195 cases who underwent IUI treatment in our hospital.The pregnancy rate was 23.8% in every cycle.The pregnancy rate is 27.7% in every case.The pregnancy rate of the group undetected urinary LH was 17.3%,which significantly decreased in detected group(29.0%,28.3%)(P<0.05).The ovulation rulation rate of the group undetected urinary LH was(34.7%) in 24 hours after IUI,which decreased in the group detected urinary LH(50.7%,51.7%).(P<(0.05)) In the same time the pregnancy rate of each group was 38.2%,37.1% and 32.3%.There was not significant different in any of them. Conclusion: It was an important index for choosing the best timing of IUI that the leading follicular size combine the character of urinary LH.The best timing of IUI was before ovulation and the closer to it the better.The best timing of IUI was both 24 hours after urinary LH showed positive and 36 hours after injected HCG in the case whose urinary LH showed negative.",

"abstract": "【Objective】 To probe the effect of IL-1 on the dynamic equilibrium between VEGF and ENS and to study the paroxysm of endometioma at molecular level.【Method】 The interstitial cells were separated from endometrial and cultivated alone,and added different-potency IL-1 to the descents,collected different-period culture media,and to test the expression of IL-8,VEGF and ENS by means of ELISA.Meanwhile,immunohistochemistry tow-step procedure was used to test the cultivated cells and ascertain the purity of these cultivated cells.【Results】 In the case of endometioma,the sensibility of eutopic endometrial interstitial cells under the conditions of IL-1 increased;therefore high-tone IL-8 and VEGF came into being(P <0.01).Under the conditions of a certain-dense IL-1,the expression of IL-8 and VEGF increased with the time extension,which depended on time.The expressions of IL-8 and VEGF under the conditions of different-dense IL-1 depended on the dosage of IL-1.In the case of endometioma,the expression of ENS in the eutopic endometrial culture media,under the conditions of IL-1,had no obvious difference from the normal control group;moreover,the expression of ENS was not related to the change of time or dense of IL-1 at all.【Conclusion】 In the case of endometioma,the expression of IL-8 and VEGF ineutopic endometrial interstitial cells becomes strong under the conditions of IL-1;While the expression of ENS doesn't change obviously.It is the imbalance of angiogenesis.That leads to active growth of endometrial vascellum,which may be one paroxysm of the disease.",

First, the model assumes that market clearing means equilibrium directly, avoiding the question how to conduct market adjustment without market clearing according to CAPM. Second, the model does not consider the influence of different asset scales. It only takes into account the rate of returns. However, difference in scales may have impact on people's understanding of the relationship between risks and returns. This article analyzes the two issues through an example of numerical values, finding that CAPM differs before and after market clearing, and that different asset scales have much influence on the results of CAPM.",

And the more important problem with this theory is that, while the effects are equal to each other, there will not commodity exchange emerge. So, the commodity exchange ratio can not be determined by effect. This shows that behaviors of commodity exchange in the market can not be explained by the theory of effect. And this also can be used to determine or measure value of commodity.",

"abstract": "MicroRNAs (miRNAs or miRs) are involved in phenotype modulation of neural cells after peripheral nerve injury. The effects of miRNAs on the survival of dorsal root ganglion (DRG) neurons, however, have not yet been well understood. In this study, microarray profiling indicated that 13 miRNAs were differentially expressed in rat DRGs (L4-L6) during the initial 7d period post sciatic nerve transection, and that the expressions of miR-21 and miR-222 (2 out of the 13 miRNAs) were continually increased over the time period. Tissue inhibitor of metalloproteinase 3 (TIMP3), a pro-apoptotic protein in various cancer cells, was identified as a common target of miR-21 and miR-222. Over-expression of miR-21 and miR-222 inhibited cell apoptosis and enhanced cell viability in cultured DRG neurons. IL-6 could induce up-regulation of miR-21 expression. All the results showed that miR-21 and miR-222 inhibited neuronal apoptosis at least partially through suppressing TIMP3 after peripheral nerve injury.",

"abstract": "The inhibitory environment that surrounds the lesion site and the lack of intrinsic regenerative capacity of the adult mammalian central nervous system (CNS) impede the regrowth of injured axons and thereby the reestablishment of neural circuits required for functional recovery after spinal cord injuries (SCI). To circumvent these barriers, biomaterial scaffolds are applied to bridge the lesion gaps for the regrowing axons to follow, and, often by combining stem cell transplantation, to enable the local environment in the growth-supportive direction. Manipulations, such as the modulation of PTEN/mTOR pathways, can also enhance intrinsic CNS axon regrowth after injury. Given the complex pathophysiology of SCI, combining biomaterial scaffolds and genetic manipulation may provide synergistic effects and promote maximal axonal regrowth. Future directions will primarily focus on the translatability of these approaches and promote therapeutic avenues toward the functional rehabilitation of patients with SCIs.",

"abstract": "The regulation of Schwann cell (SC) responses to injury stimuli by microRNAs (miRNAs) remains to be explored. Here, we identified 17 miRNAs that showed dynamic expression alterations at five early time points following rat sciatic nerve resection. Then we analyzed the expression pattern of 17 miRNAs, and integrated their putative targets with differentially expressed mRNAs. The resulting 222 potential targets were mainly involved in cell phenotype modulation, including immune response, cell death and cell locomotion. Among 17 miRNAs, miR-182 expression was up-regulated. The enhanced expression of miR-182 was correlated with nerve injury-induced phenotype modulation of SCs. Further investigation revealed that fibroblast growth factor 9 (FGF9) and neurotrimin (NTM) were two direct targets of miR-182 in SCs, with miR-182 binding to the 3'-untranslated region of FGF9 and NTM. Silencing of FGF9 and NTM recapitulated the inhibiting effect of miR-182 mimics on SC proliferation and migration, respectively, whereas enforced knockdown of FGF9 and NTM reversed the promoting effect of miR-182 inhibitor on SC proliferation and migration, respectively. Our data indicate that nerve injury inhibits SC proliferation and migration through rapid regulation of miR-182 by targeting FGF9 and NTM, providing novel insights into the roles of miRNAs in nerve injury and repair.",

"abstract": "Dorsal root ganglia (DRG) neurons spontaneously undergo robust neurite growth after axotomy. Long noncoding RNAs (lncRNAs) are an important class of pervasive genes involved in a variety of biological functions. However, the functions of lncRNAs in the regulation of responses of DRG neurons to injury stimuli remain untested. Here, lncRNA microarray analysis was performed to profile the lncRNAs in L4-L6 DRGs following rat sciatic nerve resection. The 105 lncRNAs were identified to be differentially expressed at 0, 1, 4, 7 d post injury. A coexpression network of 24 down-regulated lncRNAs and coding genes was constructed, and 115 targets of these 24 lncRNAs were found to be mainly involved in cell phenotype modulation, including glial cell migration, purinergic nucleotide receptor signaling pathway, vasodilation, regulation of multi-organism process, and neuropeptide signaling pathway, and also to be potentially associated with several key regeneration signaling pathways, including MAPK signaling pathway, and neuroactive ligand-receptor interaction. LncRNA BC089918 was selected from 24 down-regulated lncRNAs for validation by quantitative real-time polymerase chain reaction and in situ hybridization. And silencing of BC089918 with small interfering RNAs indicted that the lncRNA had a particular promoting effect on neurite outgrowth. Our data demonstrated a distinct involvement of lncRNAs in DRGs after nerve injury, thus contributing to illustration of molecular mechanisms responsible for nerve regeneration.",

"abstract": "The regulative effects of microRNAs (miRNAs) on responses of Schwann cells to a nerve injury stimulus are not yet clear. In this study, we noted that the expression of eight miRNAs was downregulated at different time points following rat sciatic nerve transection, and found that 368 potential targets of these eight miRNAs were mainly involved in phenotypic modulation of Schwann cells. Of these miRNAs, miR-9 was identified as an important functional regulator of Schwann cell migration that was a crucial regenerative response of Schwann cells to nerve injury. In vitro, upregulated expression of miR-9 inhibited Schwann cell migration, whereas silencing of miR-9 promoted Schwann cell migration. Intriguingly, miR-9 exerted this regulative function by directly targeting collagen triple helix repeat containing protein 1 (CTHRC1), which in turn inactivated downstream Rac1 GTPase. Rac1 inhibitor reduced the promotive effects of anti-miR-9 on Schwann cell migration. In vivo, high expression of miR-9 reduced Schwann cell migration within a regenerative nerve microenvironment. Collectively, our results confirmed the role of miR-9 in regulating Schwann cell migration after nerve injury, thus offering a new approach to peripheral nerve repair.",

"abstract": "Peripheral nerve injury is a common clinical problem. Nerve growth factor (NGF) promotes peripheral nerve regeneration, but its clinical applications are limited by several constraints. In this study, we found that the time-dependent expression profiles of eight let-7 family members in the injured nerve after sciatic nerve injury were roughly similar to each other. Let-7 microRNAs (miRNAs) significantly reduced cell proliferation and migration of primary Schwann cells (SCs) by directly targeting NGF and suppressing its protein translation. Following sciatic nerve injury, the temporal change in let-7 miRNA expression was negatively correlated with that in NGF expression. Inhibition of let-7 miRNAs increased NGF secretion by primary cultured SCs and enhanced axonal outgrowth from a coculture of primary SCs and dorsal root gangalion neurons. In vivo tests indicated that let-7 inhibition promoted SCs migration and axon outgrowth within a regenerative microenvironment. In addition, the inhibitory effect of let-7 miRNAs on SCs apoptosis might serve as an early stress response to nerve injury, but this effect seemed to be not mediated through a NGF-dependent pathway. Collectively, our results provide a new insight into let-7 miRNA regulation of peripheral nerve regeneration and suggest a potential therapy for repair of peripheral nerve injury.",

"abstract": "The peripheral nervous system is able to regenerate after injury, and regeneration is associated with the expression of many genes and proteins. MicroRNAs are evolutionarily conserved, small, non-coding RNA molecules that regulate gene expression at the level of translation. In this paper, we focus on the identification and functional annotation of novel microRNAs in the proximal sciatic nerve after rat sciatic nerve transection. Using Solexa sequencing, computational analysis, and quantitative reverse transcription PCR verification, we identified 98 novel microRNAs expressed on days 0, 1, 4, 7, and 14 after nerve transection. Furthermore, we predicted the target genes of these microRNAs and analyzed the biological processes in which they were involved. The identified biological processes were consistent with the known time-frame of peripheral nerve injury and repair. Our data provide an important resource for further study of the role and regulation of microRNAs in peripheral nerve injury and regeneration.",

"title": "miR-221 and miR-222 promote Schwann cell proliferation and migration by targeting LASS2 after sciatic nerve injury.",
"abstract": "microRNAs (miRNAs) are small non-coding RNAs that regulate gene expression at the post-transcriptional level. Their roles in regulating the responses of Schwann cells (SCs) to injury stimuli remain unexplored. Here we report dynamic alteration of miRNA expression following rat sciatic nerve injury using microarray analysis. We harvested the proximal nerve stumps and identified 77 miRNAs that showed significant changes at four time points after nerve transection. Subsequently, we analyzed the expression pattern of miRNA, selected one significant profile, and then integrated putative miRNA targets with differentially expressed mRNA yielding 274 potential targets. The 274 targets were mainly involved in cell proliferation, cell locomotion and cellular homeostasis that were known to play important roles in modulating cell phenotype. The upregulation of the miR-221 and miR-222 cluster (miR-221/222) was found to correlate with the injury-induced SC phenotypic modulation. Enhanced expression of miR-221/222 could promote SC proliferation and migration in vitro, whereas silencing their expression resulted in a reduced proliferation and migration. Further studies revealed that longevity assurance homologue 2 (LASS2) was a direct target of miR-221/222 in SCs because miR-221/222 bound directly to the 3'-untranslated region of LASS2, thus reducing both mRNA and protein levels of LASS2. Silencing of LASS2 recapitulated the effects of miR-221/222 mimics, whereas enforced knockdown of LASS2 reversed the suppressive effects of miR-221/222 inhibitors. Our findings indicate that injury promotes SC proliferation and migration through the regulation of miR-221/222 by targeting LASS2, and provide new insights into the role of miRNAs in nerve regeneration.",

"abstract": "The aim of this study was to evaluate, in a meta-analysis, the clinical effectiveness of operative treatment for acute Achilles tendon rupture (AATR) compared with nonoperative treatment.We systematically searched six electronic databases (Medline, Embase, Clinical Ovid, BIOSIS and Cochrane registry of controlled clinical trials) to identify randomised controlled trials (RCTs) in which operative treatment was compared with nonoperative treatment for AATR from 1980 to 2011. Trial quality was assessed using the modified Jadad scale. The data was using fixed-effects and random-effects models with mean differences and risk ratios for continuous and dichotomous variables, respectively.Ten RCTs with a total of 894 patients were screened. The results showed that operative was superior to nonoperative treatment regarding lower risk of re-rupture (P = 0.002) and shorter time for sick leave (P = 0.009) but inferior to nonoperative treatment regarding complication risks (P = 0.004). No significant difference was identified between the two methods regarding the number of patients who successfully returned to pre-injury sports (P = 0.30). Subgroup analyses revealed significant differences in relation to scar adhesion (P < 0.00001), superficial infection (P = 0.05), and sensibility disturbance (P = 0.0003). However, no significant differences were found between the two interventions in relation to deep infection (P = 0.22), deep vein thrombosis (DVT) (P = 0.14), and extreme Achilles tendon lengthening (P = 0.31). Little consensus was obtained in the functional recovery from current trials as a result of an inconsistent assessment system.Compared with conservative treatment, operative treatment can effectively reduce the risk of re-rupture but increase the probability of complications. The increased complication risk may be associated with open repair surgery. However, no sufficient evidence is available from current studies to support the belief that operation may lead to better functional recovery.",

"abstract": "Tumor necrosis factor-α (TNF-α) is a pluripotent signaling molecule. The biological effect of TNF-α includes slowing down osteogenic differentiation, which can lead to bone dysplasia in long-term inflammatory microenvironments. Signal transducer and activator of transcription 3 (STAT3)-interacting protein 1 (StIP1, also known as elongator complex protein 2, ELP2) play a role in inhibiting TNF-α-induced osteoblast differentiation. In the present study, we investigated whether and how ELP2 activation mediates the effects of TNF-α on osteoblastic differentiation. Using in vitro cell cultures of preosteoblastic MC3T3-E1 cells, we found that TNF-α inhibited osteoblastic differentiation accompanied by an increase in ELP2 expression and STAT3 activation. Forced ELP2 expression inhibited osteogenic differentiation of MC3T3-E1 cells, with a decrease in the expression of osteoblast marker genes, alkaline phosphatase activity, and matrix mineralization capacity. In contrast, ELP2 silencing ameliorated osteogenic differentiation in MC3T3-E1 cells, even after TNF-α stimulation. The TNF-α-induced inhibitory effect on osteoblastic differentiation was therefore mediated by ELP2, which was associated with Janus kinase 2 (JAK2)/STAT3 activation. These results suggest that ELP2 is upregulated at the differentiation of MC3T3-E1 cells into osteoblasts and inhibits osteogenic differentiation in response to TNF-α through STAT3 activation.",

During the onset of OA, articular cartilage and subchondral bone act in concert as a functional unit. This present study is to investigate the effects of early or late treatment with recombinant lubricin on the onset of osteoarthritis (OA) in ovariectomized (OVX) rats. We found that both early and late recombinant lubricin treatments attenuated the onset of OA by positive feedback loop between articular cartilage and subchondral bone, although late treatment contributed to a lesser effect compared with early treatment. Specifically, treatment with recombinant lubricin protected articular cartilage from degeneration, demonstrated by lower proteoglycan loss, lower OARSI scores, less calcification cartilage zone and reduced immunostaining for collagen X (Col X) and matrix metalloproteinase (MMP-13) but increased the expression of lubricin, in comparison with vehicle-treated OVX rat group. Further, chondroprotective effects of lubricin normalized bone remodeling in subchondral bone underneath. It's suggested that treatment with recombinant lubricin inhibited the elevation of TRAP and Osterix positive cells in OVX rats and led to the normalization of subchondral bone microarchitectures with the suppression of subsidence of bone volume ratio (BV/TV) and trabecular thickness (Tb.Th) and the increase of trabecular separation (Tb.Sp) in vehicle-treated OVX rats. What's more, the normalization of subchondral bone in turn attenuated the articular cartilage erosion by inhibiting vascular invasion from subchondral bone to calcified cartilage zone, exemplified by inhibiting the elevation of CD31 positive cells in calcified cartilage and angiography in subchondral bone. Together, these results shed light that both early and late recombinant lubricin treatments attenuate the onset of OA by balancing the interplay between articular cartilage and subchondral bone in OVX rats, while also providing a further rationale for its therapeutic targeting to postmenopausal OA and suggesting that treatment timing is a pivotal factor for better effect acquisition.",

"abstract": "Bone loss in ( ) osteomyelitis poses a serious challenge to orthopaedic treatment. This study aimed to elucidate how infection in bone might induce bone loss. The C57BL/6 mice were injected with (10 CFU/ml, 100 μl) or with the same amount of vehicle (control) via the tail vein. MicroCT analysis showed bone loss progressing from week 1 to week 5 after infection, accompanied by a decreased number of osteocalcin-positive stained osteoblasts and the suppressed mRNA expression of Runx2 and osteocalcin. Transcriptome profiles of GSE30119 were downloaded and analyzed to determine the differences in expression of inflammatory factors between patients with infected osteomyelitis and healthy controls, the data showed significantly higher mRNA expression of granulocyte colony-stimulating factor (G-CSF) in the whole blood from patients with infection. ELISA analysis confirmed an increased level of G-CSF in the bone marrow and serum from infected mice, which might have been due to the increased amount of F4/80 macrophages. Interestingly, G-CSF neutralizing antibody treatment significantly rescued the bone loss after infection, as evidenced by its roles in improving BV/TV and preserving osteocalcin- and osterix-positive stained cells. Importantly, we found that G-CSF level was significantly up-regulated in the serum from osteomyelitis patients infected by Together, infection might suppress the function of osteoblastic cells and induce progressive bone loss by up-regulating the level G-CSF, suggesting a therapeutic potential for G-CSF neutralization in combating bone loss in osteomyelitis.",

"abstract": "Bone substitute offers a promising strategy for the reconstruction of large bone defects. It may be feasible to develop a better substitute material by enhancing the osteoinductivity and delaying the degradation of α-calcium sulfate hemihydrate. In this study, nano cerium oxide was incorporated with α-calcium sulfate hemihydrate at weight ratios of 5 and 10% to form nano cerium oxide-containing α-calcium sulfate hemihydrate. Extracts from α-calcium sulfate hemihydrate, 5 and 10% nano cerium oxide-containing α-calcium sulfate hemihydrate were prepared for in vitro treatment of cells. After critical bone defects were made on the left tibia of male Sprague-Dawley rats, the animals were randomly divided into four groups subjected to the filling with nothing (blank), α-calcium sulfate hemihydrate (control), 5 and 10% nano cerium oxide-containing α-calcium sulfate hemihydrate. Extraction from 5% nano cerium oxide-containing α-calcium sulfate hemihydrate composite stimulated cells proliferation and increased cell migration and mRNA expression of osteoblastic marker genes in primary bone marrow stromal cells. X-ray and micro-computed tomography analyses showed increased bone formation and reduced degradation, and histological analysis showed mineralized staining on the boundary area between composites and bone marrow in the nano cerium oxide-containing α-calcium sulfate hemihydrate group. Immunostaining of osteocalcin confirmed the increased bone formation in the nano cerium oxide-containing α-calcium sulfate hemihydrate group. Nano cerium oxide-containing α-calcium sulfate hemihydrate composite with 5% w/w nano cerium oxide showed a better capacity of enhancing osteogenesis and bone regeneration model than 10% cerium oxide-containing α-calcium sulfate hemihydrate composite. The findings suggested that the nano cerium oxide-containing α-calcium sulfate hemihydrate might be a potential material for bone substitutes since it may promote local bone regeneration.",

"abstract": "Regarding the treatment of humeral shaft fractures, the choice of plating or intramedullary nailing remains controversial. Previous randomized controlled trials and meta-analyses failed to draw a unanimous conclusion. To guide clinical decision making, we conducted an updated meta-analysis on the optimal treatment of humeral shaft fractures.We identified eligible studies published from 1969 to July 2011 using the Cochrane Library; Cochrane Bone, Joint and Muscle Trauma Group; MEDLINE; Embase; OVID; and Google Scholar and manually searched the references of relevant studies. Randomized controlled trials that compared nailing and plating in the treatment of humeral shaft fractures were included. After the methodologic assessment, available data were extracted and statistically reviewed. The primary outcomes were nonunion, delayed union, postoperative infection, reoperation, and radial nerve palsy. The secondary outcomes were restriction of shoulder motion, shoulder impingement, iatrogenic fracture comminution, and implant failure.We included 10 studies comparing plating and nailing in patients with humeral shaft fractures, comprising 439 participants. Plating reduced the risk of shoulder impingement and shoulder restriction in comparison with nailing. Regarding reoperation risk, a secondary sensitivity analysis showed the finding favoring plating over nailing remained unstable. Otherwise, no significant differences were found in postoperative infection, nonunion, delayed union, radial nerve palsy, iatrogenic fracture comminution, and implant failure between groups.On the basis of current evidence, both plating and nailing can achieve a similar treatment effect on humeral shaft fractures, but plating may reduce the occurrence of shoulder problems. Randomized controlled trials with larger sample sizes using appropriate blinding methods are needed to confirm these findings.Level II, Meta-analysis of prospective comparative trials.",

The running groups were trained on treadmill for 6 consecutive weeks. Blood samples were collected to detect serum MMP-3 and TIMP-1 levels using ELISA before and after the experiment, and the femoral trochlea were collected to assess tissue repair by gross appearance scoring and O Driscoll histological scoring with Safranine O-Fast Green staining and Toluidine blue staining.In rats in SED group, the defect was filled with hyaline articular cartilage-like tissues, as compared to fibrous tissues in LIR and MIR groups and subchondral bone damage in HIR group. The SED group scored the highest and HIR group the lowest among the 4 groups in gross appearance scoring and O Driscoll histological scoring. No significant differences were found in MMP-3 or TIMP-1 levels among the groups before training (P>0.05), but after 6 weeks of training, serum MMP-3 and TIMP-1 levels differed significantly among the 4 groups (P<0.05), and all the 3 running groups had a significantly higher MMP-3 level than the control group (P<0.05). After the 6-week training, TIMP-1/MMP-3 ratio was significantly higher in SED group than in the 3 running groups, and was the lowest in HIR group.Both low- and moderate-intensity exercise failed to promote resurfacing of full-thickness cartilage defects on the patellofemoral articular surface in rats, and high-intensity exercise even induces subchondral bone damage.

"abstract": "The extent of substrate stiffness has been shown to be predominant in regulating cellular behaviors. Previous studies have used matrices such as elastomers or hydrogels to understand cell behavior. Herein, liquid crystalline matrices that resemble movable morphology of biomembrane and viscoelasticity were fabricated with tunable storage modulus for the evaluation of the modulus-driven cell behaviors. Our results demonstrated that NIH/3T3 cells showed a hypersensitive response to the storage modulus of liquid crystalline substrates by the alteration in attachment, spreading, proliferation and viability, polarization, cell cycle and apoptosis, and activity of mechano-transduction-related signal molecules including FAK, paxillin and ERK. The octyl hydroxypropyl cellulose substrates (OPC-1-5) with intermediate storage modulus of 12,312Pa and 7228Pa (OPC-2 and OPC-3 respectively) could provide more beneficial adhesion conditions leading to a larger spreading area, more elongated morphology and higher proliferation rates possibly through paxillin-ERK pathway, whereas the substrates with the highest or lowest storage modulus (16,723Pa, OPC-1; and 41Pa, OPC-5, respectively) appeared unfavorable for cell growth. Our study provides insights into the mechanism of modulus-driven cellular behaviors for better design of bioengineered cell substrates.",

"title": "Strontium‑containing α‑calcium sulfate hemihydrate promotes bone repair via the TGF‑β/Smad signaling pathway.",
"abstract": "Calcium phosphate‑based bone substitutes have been widely used for bone repair, augmentation and reconstruction in bone implant surgery. While some of these substitutes have shown excellent biological efficacy, there remains a need to improve the performance of the current calcium phosphate‑based bone substitutes. Strontium ions (Sr) can promote new osteogenesis, inhibit osteoclast formation and increase osteoconductivity. However, the therapeutic effect and mechanism of strontium‑containing α‑calcium sulfate hemihydrate (Sr‑CaS) remains unclear. The present study created bone injuries in rats and treated the injuries with Sr‑CaS. Then Cell Counting Kit‑8, soft agar colony formation, flow cytometry, Transwell and Alizarin Red staining assays were performed to assess the bone cells for their proliferation, growth, apoptosis, invasion, and osteogenic differentiation abilities. The bone reconstructive states were measured by the microCT method, hematoxylin and eosin staining and Masson staining. Bone‑related factors were analyzed by the reverse transcription‑quantitative PCR assay; transforming growth factor (TGF)‑β, mothers against decapentaplegic homolog (Smad)2/3 and β‑catenin expression was measured by western blot analysis and osteocalcin (OCN) expression was assessed by immunohistochemistry. Sr‑CaS did not significantly affect the proliferation and apoptosis of bone marrow stem cells (BMSCs), but did accelerate the migration and osteogenic differentiation of BMSCs in vitro. Sr‑CaS promoted bone repair and significantly increased the values for bone mineral density, bone volume fraction, and trabecular thickness, but decreased trabecular spacing in vivo in a concentration‑-dependent manner. In addition, Sr‑CaS dramatically upregulated the expression levels of genes associated with osteogenic differentiation (Runt‑Related Transcription Factor 2, Osterix, ALP, OCN and bone sialoprotein) both in vitro and in vivo. Sr‑CaS also increased Smad2/3, TGF‑β and phosphorylated‑β‑catenin protein expression in vitro and in vivo. These results indicated that materials that contain 5 or 10% Sr can improve bone defects by regulating the TGF‑β/Smad signaling pathway.",

"title": "Effect of intra-articular ozone injection on degenerative knee cartilage in rats",
"abstract": "This study explored the therapeutic effects of medical ozone on cartilage in animal models of osteoarthritis (OA). Forty healthy adult Sprague-Dawley rats were randomly divided into five equal groups: group A (normal), group B (model), group C (air), group D (35μg/ml O 3) and group E (70 μg/ml O 3). OA models were created by transecting the anterior cruciate ligament (ACL) and excising a third of the medial meniscus in groups B, C, D and E. Air was injected into the joints in group C. Ozone with 35 μg/ml O 3 and 70 μg/ml O 3 were injected into the joints in groups D and E respectively every other day, with 1-1.5 ml each time. Injections were made altogether for two weeks at one week intervals. The animals were killed after four weeks to harvest condylar cartilage of femur for HE staining and observation under a transmission microscope. Mankin's indexes were recorded. Douche fluids from the diseased joints were obtained for measurement of superoxide dismutase (SOD) and malondialdehyde (MDA). In OA models of group B, obviously degenerative changes were observed under microscopy, resulting in mostly blue and green color destaining of Masson staining in superficial cartilage. The activity of SOD in the douche fluid from the diseased joints decreased and the quantity of MDA in the serum increased. Mankin's indexes in group D were significantly higher than those in groups B and C (P<0. 05), but not significantly different from those in group A. SOD levels were increased and MDA levels decreased. There were no significant differences between groups E and B in Mankin's indexes. SOD levels decreased and MDA levels increased. 35 μg/ml O 3 can prevent degeneration of articular cartilage and improve the ability to clear free radicals, but 70 μg/ml O 3 may result in peroxidatic reaction of tissue and cells, leading to articular cartilage damage.",

"abstract": "Repair of bone defects presents a serious clinical challenge as it is difficult to restore bone function and regenerate bone loss. In the present study, the effects of lentivirus‑mediated transfection of bone marrow mesenchymal stem cells (BMSCs) with microRNA (miR)‑26a on bone regeneration were investigated in a mouse bone defect repair model. Marker of proliferation Ki67 (Ki67) staining was employed to detect the cell proliferation capacity and alkaline phosphatase (ALP) staining was used to investigate osteogenic differentiation. A mouse model of cranial bone defects was established. β‑tricalcium phosphate biomaterials co‑cultured with the transfected BMSCs were implanted into the defect areas of mouse models. Micro‑computed tomography, and hematoxylin and eosin and toluidine blue staining, were used to detect bone regeneration in the defect areas and the degradation of scaffolds. miR‑26a expression, and the mRNA and protein expression of osteogenesis‑associated cytokines, were detected using reverse transcription‑quantitative polymerase chain reaction and western blot analysis. Separated and cultured BMSCs highly expressed CD29 and CD105, but not CD34 and CD45, as determined by flow cytometry. miR‑26a expression and the positive cell rate of Ki67 and ALP staining in BMSCs transfected with pLVTHM‑miR‑26a were increased. The BMSC and negative control‑transfected BMSC groups exhibited increased bone regeneration in the defect areas, increased bone volume of newly formed bones, and elevated mRNA and protein expression of runt‑related transcription factor 2 (Runx2) and osteocalcin (OC), compared with the blank group. However, the miR‑26a‑transfected BMSC group exhibited further increases in bone regeneration and the volume of newly formed bones, and further elevations of the mRNA and protein expression levels of Runx2 and OC. The present findings demonstrated that lentivirus‑mediated modification of BMSCs enhanced bone regeneration during the repair of cranial bone defects in mice.",

Previous study of Banchereau et al. has established a link between whole blood transcription profiles and clinical manifestations in patients infected with . However, the differentially expressed genes (DEGs) in OM induced by infection have not been intensively investigated. In this study, we downloaded the gene expression profile dataset GSE30119 from Gene Expression Omnibus, and performed bioinformatic analysis to identify DEGs in infection induced OM from the transcriptional level. The study consisted of 143 whole blood samples, including 44 healthy controls, 42 OM-free, and 57 OM infection patients. A total of 209 infection-related genes (SARGs) and 377 OM-related genes (OMRGs) were identified. The SARGs were primarily involved in the immune response by GO functional and pathway enrichment analysis. Several proteins adhere to neutrophil extracellular traps may be critical for the immune response to the process of infection. By contrast, the OMRGs differ from the SARGs. The OMRGs were enriched in transmembrane signaling receptor and calcium channel activity, cilium morphogenesis, chromatin silencing, even multicellular organism development. Several key proteins, including PHLPP2 and EGF, were hub nodes in protein-protein interaction network of the OMRGs. In addition, alcoholism, systemic lupus erythematosus and proteoglycans in cancer were the top pathways influenced by the OMRGs associated with OM. Thus, this study has further explored the DEGs and their biological functions associated with infection and OM, comparing with the previous study, and may light the further insight into the underlying molecular mechanisms and the potential critical biomarkers in OM development.",

The search strategy followed the requirements in the Cochrane Library Handbook. The primary outcome was retearing of the rotator cuff. Functional outcomes were analyzed in terms of Constant score, specific Constant pain score, University of California, Los Angeles (UCLA) shoulder score, Simple Shoulder Test (SST) score, and American Shoulder and Elbow Surgeons (ASES) score.Seven studies with a total of 417 patients available at the latest follow-up reporting data about retears were analyzed in this meta-analysis. However, 4 studies with Constant scores (n = 237), 3 studies with UCLA scores (n = 168), 2 studies with Constant pain scores (n = 164), 2 studies with ASES scores (n = 101), and 2 studies with SST scores (n = 121) were analyzed. The retear rates and functional scores showed that there was no significant efficacy of PC application in arthroscopic rotator cuff repairs.This meta-analysis of high-level evidence suggests that PCs have no benefit regarding retear rate and overall clinical outcomes for the arthroscopic repair of full-thickness rotator cuff tears.Level II, meta-analysis of randomized controlled trials.",

"abstract": "To explore the surgical technique and clinical value of treatment for posttraumatic large circular soft tissue defect in the lower extremities using a combination of posterior tibial vascular bridge flap in the unaffected leg and skin graft covered by vacuum sealing drainage (VSD).From January 2008 to June 2010, 11 cases with posttraumatic large circular soft tissue defects with deep tissue exposed or partial necrosis in the lower extremities were treated by bridge flaps and combined with free skin graft covered by VSD. There are 7 males and 4 females, with an average age of 32.5 years (range from 15 to 52 years). The size of wound varied from 24 cm × 13 cm to 45 cm × 24 cm. After the wound were completely debrided, the external fixation or internal fixation was conducted for the patients with unstable fracture. Then VSD were used to covered the wound for 1-2 times with a period of 5 to 7 days according to the wound condition. After granulation tissue grew, bridge flap transplantation was performed to repair tissue defect and cover the exposed bone, which combined with skin graft covered by VSD was used to cover the residual wound. Survival rate and quality healing of the flaps were followed up postoperatively.The granulation growth of 11 cases with large circular soft tissue defect in the lower extremities associated tissue exposure was good after the application of VSD. All the cases were covered by free flap transplantation and skin grafting except for 6 cases due to large defect. The wound was covered by skin re-grafting in 4 cases and frequently dressing change in 2 cases. All the flaps were successful with good infection control and no sinus. The average period of follow-up was 10.6 months (5 - 24 months). All the patients were satisfied with the good outline and good function of the affected limb.Patients with posttraumatic large circular soft tissue defect in the lower extremities can be effectively treated with a combination of bridge flaps and free skin graft covered by VSD, which can shorten the course of treatment, and restore the function of affected extremities as much as possible.",

"abstract": "To investigate the clinical results of the flap pedicled with collateral branch of descending rarus of lateral circumflex femoral artery with digital three-dimensional reconstruction technique for lower limb soft tissue defects.Between March 2009 and January 2010, 7 patients with lower limb soft tissue defects were treated with free flap pedicled with collateral branch of descending rarus of lateral circumflex femoral artery. There were 6 males and 1 female with an age range from 6 to 51 years. They were injured by traffic accident (4 cases), or by object hit from height (3 cases). The locations were foot in 2 cases, ankle in 2 cases, and anterior tibia in 3 cases. The disease duration was 8 hours to 40 days (mean, 20 days). All the cases complicated by exposure of tendons or bones. The areas of soft tissue defect ranged from 12 cm x 7 cm to 20 cm x 14 cm. Free flaps were transplanted at 4 to 16 days after symptomatic treatment. Before operation, all the flaps were designed with digital three-dimensional reconstruction technique. The size of flaps ranged from 15 cm x 9 cm to 22 cm x 16 cm. The donor sites were closed directly in all cases.All the flaps survived. The wounds and incisions at donor sites healed by first intention. All the patients were followed up 6 to 12 months. The texture, appearance, and function of the flaps were satisfactory, and no complication occurred. All the flaps had protective sensation, which could meet the requirement of the daily life. The function of ankle was satisfactory with normal walk; the extension was 19-22 degrees and the flexion was 30-36 degrees. No obvious scar formed at donor sites.The flap pedicled with collateral branch of descending rarus of lateral circumflex femoral artery has reliable blood supply, easy operation, little influence on the donor site, and high success rate with digital three-dimensional reconstruction technique. It is an excellent option for repairing lower limb soft tissue defects.",

"abstract": "Proinflammatory cytokine interleukin-1β (IL-1β) plays a crucial role in the pathogenesis of Osteoarthritis (OA) by stimulating several mediators contributed to cartilage degradation. Aucubin, a natural compound derived from plants which has been shown to possess diverse biological activities including anti-inflammatory property, may benefit the IL-1β stimulated chondrocytes. The present study was aimed to investigate the effects of Aucubin on IL-1β stimulated rat chondrocytes. Rat chondrocytes were cultured and pretreated with Aucubin (1, 10, 20, 50μM), and then stimulated with or without IL-1β (10ng/ml). Gene and protein expression of MMP-3, MMP-9, MMP-13, cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) was determined by real-time PCR and Western blotting respectively. Nitric oxide (NO) production was quantified by Griess reagent. Phosphorylation and nuclear translocation of p65 were detected by western blotting and immunofluorescence, respectively. We found that Aucubin significantly reversed the elevated gene and protein expression of MMP-3, MMP-9, MMP-13, iNOS, COX-2 and the production of NO induced by IL-1β challenge in rat chondrocytes. Furthermore, Aucubin was able to suppress the IL-1β-mediated phosphorylation and nuclear translocation of p65, indicating Aucubin may possibly act via the NF-κB signaling pathway. The present study proposes that Aucubin may be a potential therapeutic choice in the treatment of OA due to its anti-inflammatory and chondroprotective features.",

Six eligible studies involving 669 fractures were included. Their methodological quality was assessed and data were extracted independently for meta-analysis.The results showed that the PFN group had significantly less operative time (WMD: -21.15, 95% CI: -34.91 - -7.39, P=0.003), intraoperative blood loss (WMD: -139.81, 95% CI: -210.39 - -69.22, P=0.0001), and length of incision (WMD: -6.97, 95% CI: -9.19 - -4.74, P<0.00001) than the DHS group. No significant differences were found between the 2 groups regarding postoperative infection rate, lag screw cut-out rate, or reoperation rate.The current evidence indicates that PFN may be a better choice than DHS in the treatment of intertrochanteric fractures.",

"abstract": "Objective To explore the possible effects of hepatocyte growth factors (HGF) on prevention and therapy of disused gastrocnemius atrophy in rats by observing their effects on the wet weight and contractile function of the gastrocnemius of fixed hind limbs. Methods Twenty-four Wister male rats were randomly divided into a blank group, a contrast group and an experimental group. Their right hind limbs were fixed for four weeks with plastic piaster from metatarsus to 1 cm up the knee. Their knee joint was fixed in 100°flexion and their ankle joint in 60°plantar flexion. Rats in the contrast group were injected with 0. 2 mL of normal saline, and rats in the ex- perimental group were injected with HGF (10 mg/kg, 10 mg/mL). Their whole gastrocnemius of the right hind limb was dissected four weeks later to measure its contractile function and wet weight. Results Compared with the blank group, single maximal contraction, maximal tetanus, and wet weight of the gastrocnemius in the contrast and experimental groups decreased significantly (P＜0. 05), and fields of electric stimulation also decreased signifi- cantly (P＜0. 05). Compared with the contrast group, single maximal contraction, maximal tetanus, and wet weight of the gastrocnemius in the experimental group were significantly superior (P＜0.05), and fields of electric stimulation significantly increased. Conclusion Since after a local injection of HGF, the contractile function and wet weight can be significantly increased, HGF may have a preventive effect on disused atrophy.",

"abstract": "Loading antibiotics in a biodegradable polymer matrix is an excellent way to control its release kinetics, which eliminates side effects caused conventional administrations of the drug. This approach is especially beneficial for bone regeneration when using a scaffold made of a biodegradable polymer loaded with drug agents capable of controllable releases. In this case, the scaffold serves as a mechanical support to tissue formation and the drug agents may provide biomolecules to assist the tissue formation and/or provide antibiotics to prevent tissues from infections. Towards this goal, we have developed an approach to make vancomycin-loaded poly(lactide-co-glycolide) (PLGA) microspheres, from which we made scaffolds by compression molding. In this article we concentrate on characterizing the porosity and drug release profiles, as well as verifying shape-memory effect of the scaffolds. The scaffold was biodegradable and showed a much slower drug release profile than micro spheres. We confirmed that our PLGA scaffolds recovered to their permanent shapes when heated to 45 degrees C. We believe that these scaffolds will find applications in bone regeneration where both the use of antibiotics against infection and accommodation to spatial restrictions may be required.

These models were imported into Imageware 12.0 software for steel osteotomy simulation until a stable hip was attained in the anatomical position for dislocation or subluxation of the hip in older children. The osteotomy navigational templates were designed according to the anatomical features after a stable hip was reconstructed. These navigational templates were manufactured using a rapid prototyping technique.The reconstruction hips in these children show good matching property and acetabulum cover.The computer-aided design of osteotomy template provides personalized and accurate solutions in the treatment of developmental dysplasia of the hip with steel osteotomy in older children.",

Results showed that the operative treatment was superior to the nonoperative treatment regarding the rate of nonunion [95 % confidence interval (CI) (0.05, 0.43), P = 0.0004], malunion [95 % CI (0.06, 0.34), P < 0.00001] and overall complication [95 % CI (0.43-0.76), P = 0.0001]. Subgroup analyses of complications revealed that significant differences were existed in the incidence of neurologic symptoms [95 % CI (0.20, 0.74), P = 0.004] and dissatisfaction with appearance [95 % CI (0.19, 0.65), P = 0.001]. Lack of consistent and standardized assessment data, insufficiency analysis that carried out showed improved functional outcomes (P < 0.05) in operative treatment.The available evidence suggests that the operative treatment for DMCF is associated with a lower rate of nonunion, malunion and complication than nonoperative treatment. This study supports traditional primary operative treatment for DMCF in active adults.",

All 344 patients were followed up for one year. The HRQoL before treatment and after one year was evaluated with the Medical Outcome Short Form 36 (SF-36).All 8 domains of HRQoL had the lowest scores greatly improved over the first year after discharge. However, the patients still had significantly lower scores in every domain than the reference group one year after discharge. Age and type of surgery were associated with HRQoL in the mental domain.The HRQoL of patients with malignant bone tumors greatly improved one year after the treatment. This study also highlighted the utility of HRQoL assessment for prognostic evaluation of patients after surgical treatment for bone cancer.",

"abstract": "Current medical practice for the treatment of articular cartilage lesions remains a clinical challenge due to the limited self-repair ability of articular cartilage. Both experimental and clinical researches show that moderate exercise can improve articular cartilage repair process. However, optimal timing of moderate exercise is unclear. We aimed to evaluate the effect of timing of moderate treadmill exercise on repair of full-thickness defects of articular cartilage.Full-thickness cartilage defects were drilled in the patellar groove of bilateral femoral condyles in a total of 40 male SD rats before they were randomly assigned into four even groups. In sedentary control (SED) group, no exercise was given; in 2-week (2W), 4-week (4W) and 8-week groups, moderate treadmill exercise was initiated respectively two, four and eight weeks after operation. Half of the animals were sacrificed at week 10 after operation and half at week 14 after operation. Femoral condyles were harvested for gross observation and histochemical measurement by O'Driscoll scoring system. Collagen type II was detected by immunohistochemistry and mRNA expressions of aggrecan and collagen type II cartilage by RT-PCR.Both 10 and 14 weeks post-operation, the best results were observed in 4W group and the worst results appeared in 2W group. The histochemistry scores and the expressions of collagen type II and aggrecan were significantly higher in 4W group than that in other three groups (P<0.05).Moderate exercise at a selected timing (approximately 4 weeks) after injury can significantly promote the healing of cartilage defects but may hamper the repair process if performed too early while delayed intervention by moderate exercise may reduce its benefits in repair of the defects.",

"abstract": "It remains controversial whether mini-incision (MI) benefits patients in total hip arthroplasty (THA). We performed a meta-analysis of randomized controlled trials (RCTs) to assess the effects of MI on surgical and functional outcomes in THA patients.A systematic electronic literature search (up to May 2013) was conducted to identify RCTs comparing MI with standard incision (SI) THA. The primary outcome measures were surgical and functional outcomes. According to the surgical approach taken, MI THA patients were divided into four subgroups for sub-group meta-analysis. Standardized mean differences (SMDs) or risk differences (RDs) with accompanying 95% confidence intervals (CIs) were calculated and pooled using a fixed-effect or random-effect model according to the heterogeneity.A total of 14 RCTs involving THA 1,174 patients met the inclusion criteria. The trials were medium risk of bias. The overall meta-analysis showed MI THA reduced total blood loss (95% CI, -201.83 to -21.18; p=.02) and length of hospital stay ( 95% CI, -0.67 to -0.08; p=.01) with significant heterogeneity. However, subgroup meta-analysis revealed posterior MI THA had perioperative advantages of reduced surgical duration ( 95% CI, -8.45 to -2.67; P<.001), less blood loss ( 95% CI, -107.20 to -1.73; P=.04) and shorter hospital stay ( 95% CI, -0.74 to -0.06; p=.002) with low heterogeneity. There were no significant differences between MI and SI THA groups in term of pain medication dose, functional outcome (HHS), radiological outcome or complications (P>.05, respectively).Although no definite overall conclusion can be arrived at on whether MI THA is superior to SI THA, posterior MI THA clearly result in a significant decrease in surgical duration, blood loss and hospital stay. It seems to be a safe minimally invasive surgical procedure without increasing the risk of component malposition or complications.",

"abstract": "NSAIDs are often ingested to reduce the pain and improve regeneration of tendon after tendon injury. Although the effects of NSAIDs in tendon healing have been reported, the data and conclusions are not consistent. Recently, tendon-derived stem cells (TDSCs) have been isolated from tendon tissues and has been suggested involved in tendon repair. Our study aims to determine the effects of COX-2 inhibitor (celecoxib) on the proliferation and tenocytic differentiation of TDSCs. TDSCs were isolated from mice Achilles tendon and exposed to celecoxib. Cell proliferation rate was investigated at various concentrations (0.1, 1, 10 and 100 μg/ml) of celecoxib by using hemocytometer. The mRNA expression of tendon associated transcription factors, tendon associated collagens and tendon associated molecules were determined by reverse transcription-polymerase chain reaction. The protein expression of Collagen I, Collagen III, Scleraxis and Tenomodulin were determined by Western blotting. The results showed that celecoxib has no effects on TDSCs cell proliferation in various concentrations (p>0.05). The levels of most tendon associated transcription factors, tendon associated collagens and tendon associated molecules genes expression were significantly decreased in celecoxib (10 μg/ml) treated group (p<0.05). Collagen I, Collagen III, Scleraxis and Tenomodulin protein expression were also significantly decreased in celecoxib (10 μg/ml) treated group (p<0.05). In conclusion, celecoxib inhibits tenocytic differentiation of tendon-derived stem cells but has no effects on cell proliferation.",

"abstract": "Clinical studies have indicated that increased serum cholesterol levels raised the risk of tendinopathy in hypercholesterolemia, but the effect of cholesterol on tendon-derived stem cells (TDSCs) and its underlying mechanism have not been studied. The purpose of this study is to investigate the association between cholesterol and tendinopathy in vitro and in vivo, and its underlying molecular mechanism as well. In TDSCs, the effect of cholesterol was assessed by quantitative polymerase chain reaction, western blot analysis, and immunofluorescence staining. Intracellular levels of reactive oxygen species (ROS) was detected, using flow cytometry. The link between nuclear factor (NF)-κB signaling and the effect of cholesterol was evaluated using a representative IκB kinase (IKK) inhibitor, BAY 11-7082. In addition, Achilles tendons from apolipoprotein E mice fed with a high-fat diet were histologically assessed using hematoxylin and eosin staining and immunohistochemistry. We found that high cholesterol apparently lowered the expression of tendon cell markers (collagen 1, scleraxis, tenomodulin), and elevated ROS levels via the NF-κB pathway both in vitro and in vivo. The ROS scavenger N-acetylcysteine (NAC) and BAY 11-7082 reversed the inhibiting effect of cholesterol on the tendon-related gene expressions of TDSCs. Moreover, NAC blocked cholesterol-induced phosphorylation of IκBα and p65. Significant histological alternation in vivo was shown in Achilles tendon in the hypercholesterolemic group. These results indicated that high cholesterol may inhibit the tendon-related gene expressions in TDSCs via ROS-activated NF-кB signaling, implying pathogenesis of tendinopathy in hypercholesterolemia and suggesting a new mechanism underlying hypercholesterolemia-induced tendinopathy.",

Subgroup analysis was conducted to determine changes of visual analog score (VAS) values at six different postoperative time points. Weighted mean differences or relative risks with accompanying 95% confidence intervals were calculated and pooled using a random effect model.Eighteen trials involving 1858 TKA patients met the inclusion criteria. The trials were liable to medium risk of bias. The VAS values at postoperative 2h, 4h, 6h, 12h, 24h, and 48h per patient were significantly lower in the LIA group than in the placebo group, and the former group also had less morphine consumption and better early functional recovery including range of motion, time to straight leg raise and 90° knee flexion than the latter group. No significant difference in length of hospital stay or side effects was detected between the two groups.The current evidence shows that the use of single-dose LIA is effective for postoperative pain management in TKA patients, with satisfactory short-term safety. More high-quality RCTs with long-term follow-ups are required for examining the long-term safety of single-dose LIA.I, II.",

"abstract": "The aim of this meta-analysis was to compare the results of arthroscopic single-bundle and double-bundle anterior cruciate ligament (ACL) reconstruction.We systematically searched electronic databases to identify randomised controlled trials (RCTs) in which arthroscopic single-bundle was compared with double-bundle for ACL reconstruction. The search strategy followed the requirements of the Cochrane Library Handbook. The outcomes of these studies were analysed in terms of graft failures, Lysholm score, negative pivot-shift test, KT1000 arthrometer measurements, knee extensor and flexor peak torques, knee extension and flexion deficit, and subjective and objective International Knee Documentation Committee (IKDC) final score. Methodological quality was assessed and data were extracted independently. Standard mean difference (SMD) or odds ratio (OR) with 95 % confidence interval (CI) was calculated by a fixed effects or random effects model. Heterogeneity across the studies was assessed with the I-square and chi-square statistic. Forest plots were also generated.We identified 17 RCTs comprising 1,381 patients who were treated by arthroscopic single-bundle versus double-bundle ACL reconstruction. The results of meta-analysis of these studies showed that arthroscopic double-bundle reconstruction was associated with a lower risk of graft failures (P=0.002) and a lower rate of positive pivot-shift test (P<0.0001). Compared with single-bundle reconstruction, double-bundle reconstruction had a lower KT1000 arthrometer measurement (P<0.00001), a lower knee extension deficit (P=0.006) and a higher subjective IKDC score (P=0.03). There was no statistically significant difference between single-bundle and double-bundle reconstruction in Lysholm score (P=0.91), knee extensor peak torques (P=0.97), knee flexor peak torques (P=0.96), knee flexion deficit (P=0.30) and objective IKDC score (P=0.18).Considering the more favourable outcomes of graft failures, knee joint stability and knee joint function in double-bundle reconstruction, we concluded that arthroscopic double-bundle reconstruction should be considered as the primary treatment in ACL reconstruction.",

"abstract": "To observe the effects of intra-articular ozone injection at different concentrations on the contents of tumor necrosis factor-α (TNF-α), TNF receptor I (TNFR I), and TNFR II in the serum and synovium of rats with rheumatoid arthritis (RA) and explore the therapeutic mechanism of ozone in RA treatment.Forty-eight Wistar rats were randomized into 8 groups, including 5 ozone groups receiving intra-articular injection of 10, 20, 30, 40 or 50 µg/ml ozone, a blank control group, an oxygen group and a RA model group. All the rats, except for those in the blank control group, were subjected to hypodermic injection of bovine collagen II and complete Freunds adjuvant to induce RA. Ozone treatment was administered once weekly for 3 weeks starting at 21 days after the modeling. The swelling and thickness of the hind paws were observed, and the serum and synovial contents of TNF-α, TNFR I, and TNFR II were detected.At the end of treatment, the paw thickness was reduced significantly in rats with 40 µg/ml ozone injection compared with that in the model RA group (P<0.01). The serum contents of TNF-α, TNFR I and TNFR II showed no significant difference between the RA model group, oxygen group and the ozone groups, but their synovial contents showed significant reductions in rats with 40 and 50 µg/ml ozone injection (P<0.01); the synovial TNFR I was significantly higher in 40 µg/ml ozone group than in the model group (P<0.05).Intra-articular injection of 40 µg/ml ozone can attenuate synovitis in rats with RA, the mechanism of which may involve the inhibition of TNF-α and TNFR II activity and enhancement of TNFR I activity in the synovium.",

"title": "Effects of hypoxia-combined-exercise on the expression of hypoxia inducible factor in skeletal muscle of rats",
"abstract": "AIM: To study the effects of hypoxia and hypoxia combined exercise on the expression of hypoxia inducible factor-1 (HIF-1)in gastrocnemius of rats, and explore the significance of exercise in hypoxia adaptation of skeletal muscles. METHODS: The experiment was conducted in Guangzhou College of Physical Education during December 2003. Eighty male SD rats aged 2 months were divided randomly into four groups according to drawing: no-exercise control group, exercise-control group, hypoxia group and hypoxia-combined-exercise group with 20 rats in each group. Hypoxia and hypoxia-combined-exercise models were made. The rats in the hypoxia group and hypoxia-combined-exercise group were put into canvas with decompression for 23 hours every day, and treadmill training was performed for 1 hour within decompression canvas, and the speed of treadmill was set at 25 m per minute. The exercise performed in the exercise-control group was the same to the former two groups. The rats in the hypoxia group were treated with the same training with those in the hypoxia-combined-exercise group except no exercise. All the experimental animals were anesthetized with 30 g/L sodium pentobarbital at the 3rd, 7th, 10th and 14th days after the beginning of experiment in batch (4 rats every time). Gastrocnemius at the left side was cut rapidly and completely. After weighing, 1 g muscle tissue was gained to make muscle slurry for preparing. Changes of contents of HIF in gastrocnemius of rats were detected with Surface-enhanced Laser Desorption/Ionization(SELDI). RESULTS: During the experiment, three rats were excluded because they could not finish the trial. Data of 77 rats were effective, and 4 rats in every group were involved in the result analysis. ① Molecular weight Mr of HIF-1 α protein was 120 167, which indicated that it had post source modification. The expression of HIF-1 α was not found at the 3rd after experiment in the no-exercise control group and hypoxia group. Expression in the exercise-control group was lower than that in the hypoxia-combined-exercise group, and its difference was significant (6.27±1.58),(14.69±1.34),P < 0.001 . ② The expression of HIF-1 α was not found at the 7th after experiment in the no-exercise control group. The expression in the exercise-control group decreased partly. The expression in the hypoxia group could be found. The expression in the hypoxia-combined-exercise group increased. There were significant differences in the hypoxia-combined-exercise group, exercise-control group and hypoxia group (20.13±0.85),(4.81±0.69),(2.27±0.61)P < 0.001. ③ The expression of HIF-1 α was still not found at the 10th after experiment in the no-exercise control group. The expression in the exercise-control group reduced partly. The expression in the hypoxia group could be found. The expression in the hypoxia-combined-exercise group increased. There were significant differences in the hypoxia-combined-exercise group, exercise-control group and hypoxia group (26.23±0.84),(3.76±0.63),(3.65±0.73),P < 0.001. ④ The expression of HIF-1 α was still not found at the 14th after experiment in the no-exercise control group. The expression in the exercise-control group fell down partly. The expression in the hypoxia group could be found. The expression in the hypoxia-combined-exercise group was fortified. There were significant differences in the hypoxia-combined-exercise group, exercise-control group and hypoxia group (29.54±0.61),(1.29±0.35),(13.47±0.62),P < 0.001. ⑤ The content of HIF had interaction with hypoxia degree, time and exercise. Under the hypoxia condition designed by this trial, the longer the hypoxia time, the higher the content in the skeletal muscles of rats that was given suitable exercise at the same time was. CONCLUSION: The hypoxia-combined-exercise can induce the expression of related gene by increasing the expression of HIF, enhance the hypoxia adaptive capacity of skeletal muscles that plays the effect of protecting skeletal muscle.",

"title": "The role of EGFR signaling in age-related osteoporosis in mice cortical bone.",
"abstract": "So far, there has been no effective cure for osteoporotic cortical bone, the most significant change in long bone structure during aging and the main cause of bone fragility fractures, because its underlying molecular and cellular mechanisms remain largely unknown. We used 3- and 15-mo-old mice as well as 15-mo-old mice treated with vehicle and gefitinib to evaluate structural, cellular, and molecular changes in cortical bone. We found that the senescence of osteoprogenitors was increased, whereas the expression of phosphorylated epidermal growth factor receptor (EGFR) on the endosteal surface of cortical bone down-regulated in middle-aged 15-mo-old mice compared with young 3-mo-old mice. Further decreasing EGFR signaling by gefitinib treatment in middle-aged mice resulted in promoted senescence of osteoprogenitors and accelerated cortical bone degeneration. Moreover, inhibiting EGFR signaling suppressed the expression of enhancer of zeste homolog 2 (Ezh2), the repressor of cell senescence-inducer genes, through ERK1/2 pathway, thereby promoting senescence in osteoprogenitors. Down-regulated EGFR signaling plays a physiologically significant role during aging by reducing Ezh2 expression, leading to the senescence of osteoprogenitors and the decline in bone formation on the endosteal surface of cortical bone.-Liu, G., Xie, Y., Su, J., Qin, H., Wu, H., Li, K., Yu, B., Zhang, X.

"abstract": "Objective To study the preventive and therapeutic effects of ginkgo biloba extract 761 on disused skeletal muscle atrophy by observing its effects on the wet weight, protein content and contraction of the gastrocnemius of fixed hindlimb in rats. Methods 24 SD rats were divided into blank group, contrast group and experimental group. Their right hind limbs were fixed for 4 weeks with plastic plaster from metatarsus to 1 cm up the knee. The knee joint was fixed in 100° flexion and the ankle joint in 60° plantar flexion. Rats in the contrast group were perfused with 3mL distilled water, and rats in the experimental group were perfused with ginkgo biloba extract 761 (120 mg/kg, 14 mg/mL). The whole gastrocnemius muscle of the right hindlimb was dissected 4 weeks later to measure its contract tension, wet weight and protein content. Results Compared with the blank group, single maximal contraction, maximal tetanus, wet weight and protein content of the gastrocnemius muscle in the contrast and experimental groups decreased significantly (P< 0.05). Compared with the contrast group, single maximal contraction, maximal tetanus, wet weight and protein content of the gastrocnemius muscle in the experimental group were significantly superior (P< 0.05). Conclusion Since Ginkgo biloba extract 761 can improve the quality, contract ability and protein content of muscles of disused atrophy, it has a preventive effect on disused atrophy.",

However, the effects of celecoxib on heterotopic ossification at other locations remain unclear. This study aimed to investigate the effect of celecoxib on heterotopic ossification in the rat model with Achilles tenotomy. Forty male Sprague-Dawley rats, which were randomly divided into 2 groups (n = 20), underwent midpoint Achilles tenotomy on left legs through a posterior approach under aseptic condition. Experimental group was treated with the saline solution of celecoxib (10 mg/kg) per day, while control group was treated by normal saline (0.9%). At 3, 5 and 10 postoperative weeks, all animals were examined by X-ray to assess new bone formation in the Achilles tendon. At 10 weeks after surgery, all animals were killed and Achilles tendons were taken for hematoxylin-eosin (HE) and immunohistochemical staining. Heterotopic ossification developed in 3 rats (15%) in experimental group and 20 rats (100%) in control group by postoperative 10 weeks. The incidence of heterotopic ossification was significantly lower in experimental group than in control group (P < 0.05). Our findings suggest that celecoxib inhibits HO development in rat model with Achilles tenotomy.",

"abstract": "Update reports are rarely available regarding the bone giant cell tumors (GCTs) in the extremity in Chinese people. The aim of this study was to review the epidemiological characteristics of bone GCT in the extremity based on the clinical data from four hospitals in South China.We searched medical electronic records from January 2001 to December 2011 in four hospitals in South China to identify patients with definite diagnosis of extremity GCT. Epidemiological data including gender, tumor site, age at the time of first diagnosis, local recurrence and pulmonary metastasis were collected and analyzed statistically. Differences between-genders were particularly analyzed regarding first diagnosis age, tumor site, local recurrence and pulmonary metastasis. T-test and Chi-square test were used for continuous and dichotomous variables, respectively.A total of 140 GCT patients (87 males and 53 females) were identified. The gender ratio was 1.64 for a male predominance. GCTs were mostly located around the knee (67 cases). 92 patients were in their 20s to 40s upon first diagnosis. The average age at the time of first diagnosis for all was 30.49 years, 30.76 years for males and 30.06 years for females (P = 0.757). GCT recurred locally in 50 patients (26 males and 24 females) with no gender difference (P = 0.065). The average interval from first surgery to local recurrence was 21.42 months. Pulmonary metastasis was found in 11 patients (8 males and 3 females) also with no gender difference (P = 0.667). The average interval from first diagnosis to metastasis was 36.45 months.Extremity GCT may have a male predominance in Chinese population and mostly occur at 20-40 years of age and around the knee. Follow-ups for GCT patients should be carried on for at least 3 years after primary surgery according to the average intervals for possible local recurrence and pulmonary metastasis.",

"abstract": "Background: The therapy of proximal humeral fractures (PHFs) in adults, especially for 3-or 4-part fractures, is still uncertain for traumatology surgeon. Objective: The aim of the study is to systematically review the outcomes of locking proximal humerus plate/proximal humeral internal locking system (LPHP/PHILOS) versus shoulder hemiarthroplasty for the treatment of PHFs in adults. Methods: According to Cochrane systematic review, Cochrane library, Medline, Embase, CNKI, VIP and Chinese Biomedical Database were retrieved for randomized controlled trials (RCTs), Quasi-RCTs and Non-RCTs comparing relevant interventions for the treatment of PHFs with LPHP/PHILOS versus shoulder hemiarthroplasty in adults. Results: Seven Non-RCTs and one Quasi-RCTs were included in this systematic review. For methodology quality, all of them were C-scale trials. There were no significant differences in the excellent and good rates of Neer between LPHP/PHILOS and shoulder hemiarthroplasty (OR=1.27, 95%CI: [0.34, 4.71], P=0.72). Neither were the incidences of complications and secondary operation between the two methods. Conclusions: There are pro and con in the treatment of PHFs by LPHP/PHILOS or shoulder hemiarthroplasty. For the elderly patients of PHFs (75years, 3 or 4-part fractures), most surgeons prefers shoulder hemiarthroplasty. The current literature offers no robust evidence to support LPHP/PHILOS is superior to shoulder hemiarthroplasty for PHFs.",

"abstract": "To identify the effects of running on articular cartilage and subchondral bone remodeling, C57BL/6 mice were randomly divided into three groups: control, moderate-, and strenuous running. Magnetic resonance imaging showed bone marrow lesions in the knee subchondral bone in the strenuous-running group in contrast with the other two groups. The microcomputed tomography analysis showed promoted bone formation in the subchondral bone in mice subjected to strenuous running. Histological and immunohistochemistry results indicated that terminal differentiation of chondrocytes and degeneration of articular cartilage were enhanced but, synthesis of platelet-derived growth factor-AA (PDGF-AA) in the subchondral bone was suppressed after strenuous running. In vitro, excessive mechanical treatments suppressed the expression of PDGF-AA in osteoblasts, and the condition medium from mechanical-treated osteoblasts stimulated maturation and terminal differentiation of chondrocytes. These results indicate that strenuous running suppresses the synthesis of PDGF-AA in subchondral bone, leading to downregulated PDGF/Akt signal in articular cartilage and thus cartilage degeneration.",

Methods Based on Cochrane Systematic Review,we searched through the MEDLINE,EMBASE,Cochrane Library and CBM disc,and relevant Chinese and English orthopedic journals by hand,and then collected all the randomized control trials(RCTs) that related to carpal tunnel syndrome.The quality of trials was critically assessed.The Revman4.2.2 that provided by Cochrane Collaboration were used for data management and analysis on the evidence of the difference in the efficacy and safety of endoscopic versus open carpal tunnel(ECTR vs.OCTR) release. Results Totally 8 RCTs were included by total retrieve and riddling.The results of meta-analysis showed no significant differences in the rate of complications,subjective satisfaction,operation time,and hand grip and pinch between groups ECTR and OCTR(P>0.05).The rate of pain and recovery time in group ECTR were lower than that in group OCTR(P<0.05). Conclusions Compared with OCTR,ECTR can reduce the postoperative pain rate and recovery time.There is no significant statistical difference on the rate of complications,subjective satisfaction,operation time,and postoperative hand grip and pinch between the two approaches.However,owing to the study quality and limited sample size,the relationship between the surgical approaches with operation time,and hand grip and pinch needs further studies.",

This study is a bacterial culture experiment of medical ozone at different concentrations (10 μg/ml, 30 μg/ml, 50 μg/ml, 80 μg/ml, using or not a disposable gas filter needle when medical ozone is obtained) from a generator 20 cm upper puff towards culture capsules for 20 minutes in a superclean bench. Sixteen Wistar rats were randomly divided into four groups (n=4). Medical ozone at different concentrations (10 μg/ml, 30 μg/ml, 50 μg/ml, 80 μg/ml) was injected into both knee cavities (0.5ml in each knee cavity) of the rats in the four groups, respectively. A disposable gas filter needle was used when medical ozone was injected into the right side, while it was not used for the left sides for control. Twenty-four hours after injection, douche fluid of the joints was obtained for bacterial culture. All blood agar plates for medical ozone gas directly cultured had no colony. As for the douche fluid culture of the joints, the control group and the fourth experimental group (80 μg/ml) had no colony. The other three groups had one blood agar plate with colonies; and the number of colonies fell as medical ozone concentration increased. Therefore, medical ozone may contain bacteria, and the disinfection of medical ozone after injection may weaken or even disappear, thus in the application of medical ozone therapy a disposable gas filter should be used with the medical ozone generator.",

Our aim was to summarise the best available evidence.Results showed that compared with external fixation, internal fixation led to significantly fewer total surgical complications [95% confidence interval (CI) 0.39-0.81, P = 0.002] and reduced the incidence of pin-track infections (95% CI 0.08-0.46, P = 0.0002) after a one year follow-up. For clinical results, grip strength (95% CI 1.59-8.25, P = 0.004), supination (95% CI 13.99-48.83, P = 0.0004) and pronation (95% CI 5.61-26.09, P = 0.002) were superior in the internal fixation group six weeks postoperatively, and the same results were obtained three months postoperatively for grip strength (95% CI 3.21-13.47, P = 0.001) and supination (95% CI 3.61-16.01, P = 0.002). Meanwhile, the Disabilities of the Arm, Shoulder and Hand (DASH) score was superior in the internal fixation group at three months (95% CI -20.62 to -2.07, P = 0.02) and after one year (95% CI -14.37 to -2.32, P = 0.007) follow-up.We suggest that the final results are significant and there is some evidence supporting the use of open reduction and internal fixation.",

"abstract": "To identify the protein regulation profile of recombinant human bone morphogenetic protein-2 (rhBMP-2)-induced osteogenic differentiation in beagle bone marrow stem cells (BMSCs).Beagle BMSCs were isolated and cultured with or without rhBMP-2. Two-dimensional gel electrophoresis was used to determine the differences in protein expression in rhBMP-2-induced and non-induced BMSCs. Real-time PCR and western blotting analyses were used to verify the expression patterns of selected proteins.After the induction, the osteogenic differentiation of beagle BMSCs was activated successfully. Nine and 11 proteins were found to be down- and up-regulated by rhBMP-2, respectively. The increase in Lim and SH3 domain protein 1(LASP1) and the decrease in ferritin were verified by real-time PCR and western blotting analyses.Among the 20 rhBMP-2-regulated factors, there is empirical evidence supporting the involvement of LASP1 and ferritin in osteogenic differentiation. LASP1 plays an important role in the regulation of the activity of the cytoskeleton, and ferritin is an important molecule in cellular iron homeostasis. Further studies focused on these 20 proteins will help elucidate the molecular mechanism(s) through which rhBMP-2 induces osteogenic differentiation of BMSCs.",

Cellular components, histological changes, growth factor expressions of IL-6, VEGF, BMP-2, and TGF-β1 in the two induced membranes were compared at 2, 4, 6 and 8 weeks, respectively. We also compared the histological changes at the bone defects between CS and PMMA groups. The structural characteristics of induced membrane were similar between CS and PMMA. Endochondral ossification took place in the CS-induced membrane at 8 week. Levels of VEGF, BMP-2 and TGF-β1 in CS-induced membrane were insignificantly higher than those in PMMA-induced membrane at different time points. The expression of IL-6 was significantly higher in PMMA-induced membranes at 2nd week. In addition, osteogenic and neovascular activities of induced membranes increased with time and peaked at 6 weeks. CS promoted endochondral ossification at the broken ends of the bone defect than PMMA did. CS-induced membrane has a better capacity of generating VEGF, BMP-2 and TGF-β1.osteogenic and neovascular activities achieve highest level at 6 week. CS may have the potential to replace PMMA as a novel spacer in Masquelet technique.",

"abstract": "Controversy still surrounds the optimal treatment for patients with displaced intra-articular calcaneal fractures (DIACF). An up-to-date meta-analysis was performed to evaluate clinical effectiveness of surgical treatment for DIACF compared with nonsurgical treatment.We systematically searched four electronic databases (Medline, BIOSIS, Cochrane library and Google Scholar) to identify randomised controlled trials (RCTs) and clinical controlled trials (CCTs) in which surgical treatment was compared with nonsurgical treatment of DIACF from 1980 to 2011. Trial quality was assessed using the modified Jadad scale and effective data were pooled for meta-analysis.Ten studies (six RCTs and four CCTs) with a total of 891 participants were screened. Results showed that surgical treatment was superior to nonsurgical treatment in better recovery of the Böhler angle (P < 0.0001), more stable calcaneal height (P = 0.0009) and width (P < 0.00001). Moreover, fewer surgically treated patients needed increased shoe size (P = 0.0004) and more were able to resume pre-injury work (P = 0.004) than the nonsurgical patients. No significant difference was identified between the two methods regarding the incidence of residual pain (P = 0.49). However, operative management was associated with a higher risk of complications (P = 0.008).Although surgical repair may increase the complication probability, it is the price that has to be paid for better reconstruction of the calcaneus and better functional results. Taken as a whole, surgery is probably the optimal choice in DIACF treatment.",

To observe the effect of PRP injection on the early healing of rat's Achilles tendon rupture so as to provide the experimental basis for clinical practice.Forty-six Sprague Dawley rats were included in this experiment, female or male and weighing 190-240 g. PRP and platelet-poor plasma (PPP) were prepared from the heart arterial blood of 10 rats; other 36 rats were made the models of Achilles tendon rupture, and were randomly divided into 3 groups (control group, PPP group, and PRP group), 12 rats for each group. In PPP and PRP groups, PPP and PRP of 100 microL were injected around the tendons once a week, respectively; in the control group, nothing was injected. The tendon tissue sample was harvested at 1, 2, 3, and 4 weeks after operation for morphology, histology, and immunohistochemistry observations. The content of collagen type I fibers also was measured. Specimens of each group were obtained for biomechanical test at 4 weeks.All the animals survived till the end of the experiment. Tendon edema gradually decreased and sliding improved with time. The tendon adhesion increased steadily from 1 week to 3 weeks postoperatively, and it was relieved at 4 weeks in 3 groups. There was no significant difference in the grading of tendon adhesion among 3 groups at 1 week and at 4 weeks (P > 0.05), respectively. The inflammatory cell infiltration, angiogenesis, and collagen fibers were more in PRP group than in PPP group and control group at 1 week; with time, inflammatory cell infiltration and angiogenesis gradually decreased. Positive staining of collagen type I fibers was observed at 1-4 weeks postoperatively in 3 groups. The positive density of collagen type I fibers in group PRP was significantly higher than that in control group and PPP group at 1, 2, and 3 weeks (P < 0.05), but no significant difference was found among 3 groups at 4 weeks (P > 0.05). The biomechanical tests showed that there was no significant difference in the maximal gliding excursion among 3 groups at 4 weeks postoperatively (P > 0.05); the elasticity modulus and the ultimate tensile strength of PRP group were significantly higher than those of control group and PPP group at 4 weeks (P < 0.05).PRP injection can improve the healing of Achilles tendon in early repair of rat's Achilles tendon rupture.",

"abstract": "Purpose: To investigate the effect of epigallocatechin-3-gallate (EGCG) on bone metabolism and osteoblastic activity. Methods: MG-63 human osteoblast-like cells were treated with varied concentrations of EGCG. Alkaline phosphatase (ALP) activity and matrix mineralization assays were carried out on the treated and untreated MG-63 human osteoblast-like cells. Beta-catenin mRNA level was determined by quantitative real-time polymerase chain reaction (q-PCR). Results: The results showed that EGCG treatment significantly increased ALP and mineralization activities at concentrations of 15 and 30 mu M, in a dose-dependent manner. Furthermore, EGCG treatment significantly increased beta-catenin mRNA expression by 70.7 +/- 11.0 and 126.7 +/- 35.1 %, respectively, at EGCG concentration of 15 and 30 mu M. In addition, the stimulating effect of EGCG treatment on ALP activity was abolished by co-treatment with ICI 182,780, an antagonist of estrogen receptor (ER). Again, the increase in beta-catenin MRNA, when treated with EGCG, was inhibited by co-treatment with ICI 182,780. Conclusion: EGCG promotes osteoblastic activity in human osteoblast-like cells, by Wnt signaling through estrogen receptor (ER) pathway.",

"abstract": "Currently, accurate diagnosis and successful treatment of infection after fracture fixation (IAFF) still impose great challenges. According to the onset of infection symptoms after implantation, IAFF is classified as early infection (<2 weeks), delayed infection (2∼10 weeks) and late infection (>10 weeks). Confirmation of IAFF should be supported by histopathological tests of intraoperative specimens which confirm infection, cultures from at least two suspected infection sites which reveal the same pathogen, a definite sinus or fistula which connects directly the bone or the implant, and purulent drainage from the wound or presence of pus during surgery. Diagnosis of IAFF is built on comprehensive assessment of medical history, clinical signs and symptoms of the patient, and imaging and laboratory tests. The gold standard of diagnosis is histopathological tests. Treatment of IAFF consists of radical debridement, adequate irrigation, implant handling, systematic and local antibiotics, reconstruction of osseous and/or soft tissue defects, and functional rehabilitation of an affected limb. Early accurate diagnosis and appropriate treatment of IAFF play a key role in increasing the cure rate, reducing infection recurrence and disability risk, restoring limb function and improving quality of life of the patient.",

"title": "The effect of intra-articular injection of different concentrations of ozone on the level of TNF-α, TNF-R1, and TNF-R2 in rats with rheumatoid arthritis.",
"abstract": "The objectives of this study were to observe the therapeutic effect of ozone (O3) of different concentrations on rat with rheumatoid arthritis (RA), and to investigate the role of O3 in regulating the level of TNF-α (tumor necrosis factor), TNF-R1 (tumor necrosis factor receptor 1), and TNF-R2. Forty-eight Wistar rats were randomly divided into eight groups. There are five O3 groups which were marked by 10, 20, 30, 40, and 50 μg/mL, respectively, control group, oxygen group, and RA model group. RA was induced in all rats by hypodermic injection of collagen II and complete Freund's adjuvant except that in the control group. At 21 days after modeling, the rats in oxygen group were given an injection of oxygen in the knee joint weekly for 3 weeks, and the rats in O3 groups were injected the concentration of O3 as they marked weekly for 3 weeks. The thickness of hind paw, as well as the serum and synovial levels of TNF-α, TNF-R1, and TNF-R2 was observed. At the end of treatments, the thickness of the hind paws in O3-40 group is much less compared to RA group (P < 0.01). The serum levels of TNF-α, TNF-R1, and TNF-R2 showed no significant difference among all the groups (P > 0.05). However, the synovial levels of TNF-α and TNF-R2 in O3-40 and O3-50 groups are lower than those in RA group (P < 0.01). The synovial level of TNF-R1 in O3-40 group is higher than that in RA group (P < 0.05). In conclusion, intra-articular injection of O3 at 40 μg/mL can effectively suppress the joint swelling caused by RA. This mechanism is probably mediated by down-regulating synovial TNF-α and TNF-R2 and up-regulating TNF-R1 in the joint.",

Computed tomography (CT) scans of a total of 120 normal adult Chinese cadaveric femurs were collected for analysis. With the three-dimensional (3D) computational technology, the anatomical fitness between the nail and bone was quantified according to the impingement incidence, maximum thicknesses and lengths by which the nail was protruding into the cortex in the virtual bone model, respectively, at the proximal, middle, and distal portions of the implant in the femur. The results showed that PFNA-II may fit better for the Chinese proximal femurs than InterTan, and the distal portion of InterTan may perform better than that of PFNA-II; the anatomic fitness of both nails for Chinese patients may not be very satisfactory. As a result, both implants need further modifications to meet the needs of the Chinese population.",

"abstract": "To review clinical characteristics of pigmented villonodular synovitis (PVNS) in China.Electronic medical records (EMR) of four Chinese institutes were queried for patients with histologically proven PVNS between January 2005 and February 2014. Their data were collected including gender, age at diagnosis, clinical presentation, affected site, symptom duration, comorbidities, treatment strategy, recurrence and routine laboratories.A total of 237 patients with biopsy-proven PVNS were investigated. The gender ratio was 1.35 for a female predominance (101 males and 136 females). The average age was 36 years (range, 2 to 83 years). The median delay from initial clinical symptom to diagnosis was 18 months. Main affected areas were the knee (73.84%) and the hip (18.14%). Forty patients had a clear history of joint trauma. Six patients were concurrently diagnosed with PVNS and avascular necrosis (AVN). Five patients suffered from PVNS following implantation of orthopaedic devices including artificial prosthesis, plate and wire. One hundred and twenty-nine patients underwent arthroscopic synovectomy and 108 open synovectomy. Altogether 48 patients (26 males and 22 females) had recurrence of disease. The relapse rate was 24% (knee) and 6.98% (hip), 20.93% (open surgery) and 19.44% (arthroscopy), respectively. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) rate were elevated in 45.83% and 38.41% of the patients respectively.To our knowledge, this study is the largest sample size of PVNS patients reported as well as the largest sample of PVNS with concurrent AVN reported to date. Our outcomes suggest that PVNS shows a female predominance, occurs mostly between 20-40 years and favors the knee and hip. Recurrence is frequent, particularly in the knee. Serum ESR and CRP may be elevated in some patients. Additionally, the present study supports the theory of an association between PVNS and orthopedic surgery, which is not limited to joint replacement.",

Objective: Based on the traditional surgical principle for metastatic bone tumors of the limbs, this study designed a user-friendly, individualized, simplistic palliative treatment regimen from the actual conditions of patients to observe the reasonability, clinical efficacy and prognosis of bone cement filling combined with internal fixation in the treatment of metastatic malignant bone tumors. Methods: Thirty-one patients with metastatic malignant bone tumors who required salvage treatment were screened from the Department of Orthopedics, the 421 Hospital of Chinese PLA, and their clinical data were retrospectively analyzed. All the 31 patients were divided into two groups: tumor removal+internal fixation group (non-chemoradiotherapy group, n=11) treated with bone cement filling plus plate internal fixation (palliative treatment); tumor removal+internal fixation+chemoradiotherapy group (chemoradiotherapy group, n=20), treated with radiotherapy before internal fixation plus plate internal fixation with limb salvage. The follow-up period was 4-38 months, averagely 18 months. Results and Conclusion: The follow-up results showed that in the non-chemoradiotherapy group, all the 11 patients survived, who could live independently and have good motor functions; in the chemoradiotherapy group, 17 of the 20 patients survived and the rest three patients died of tumor metastasis, their poor conditions and complications at 9 and 13 months after internal fixation. In patients undergoing tumor removal+plate internal fixation with limb salvage, the integrated scores for nerve and motor functions were increased by more than level 1. These findings confirm that a simple palliative therapy of bone cement filling and internal fixation without chemoradiotherapy is better for metastatic malignant bone tumors patients who require limb salvage.",

"title": "Effects of exercise intensities on expression of hypoxia inducible factor-1α mRNA in the skeletal muscle of rats",
"abstract": "Objective To study effects of exercise intensities and durations on expression of hypoxia inducible factor-1α mRNA in the skeletal muscle of rats. Methods Eighty rats were randomized into control group, low-intensity exercise group, moderate-intensity exercise group and high-intensity exercise group. Each group was further divided into four sub-groups in which rats were trained on the treadmill for one day, three days, seven days and 14 days respectively. Then cells of the skeletal muscle were observed under a transmission electron microscope and the expression of HIF-1α mRNA was detected by RT-PCR. Results HIF-1α mRNA could be basically expressed in control group during the 14 days. By contrast, there was a significant increase of HIF-1α mRNA in low-intensity exercise group at day 7(P< 0.05). The expression of HIF-1α mRNA in moderate-intensity exercise group increased significantly at both day 3 and day 7(P< 0.05). The same results were observed in high-intensity exercise group, but had no significant difference compared with those in moderate-intensity exercise group(P >0.05). At day 14, however, there was little significant difference in the result among all the groups (P >0.05). The observation by electron microscope revealed disordered skeletal muscle myofilaments, obvious swelling and partial vacuolization of mitochondria in high-intensity exercise group at day 14. Conclusions Appropriate exercise with appropriate duration can improve expression of HIF-1α mRNA in the skeletal muscle of rats which might be a positive mechanism to adjust to the exercise. Although different exercise intensities have little effect on the expression of HIF-1α mRNA, constant high-intensity exercise may damage skeletal muscles in rats.",

"abstract": "This paper describes automatic registration of the serial cross-sectional images of Chinese digital human by projective registration method based on the landmarks using the commercially available software Photoshop and Matlab. During cadaver embedment for acquisition of the Chinese digital human images, 4 rods were placed parallel to the vertical axis of the frozen cadaver to allow orientation. Projective distortion of the rod positions on the cross-sectional images was inevitable due to even slight changes of the relative position of the camera. The original cross-sectional images were first processed using Photoshop software firstly to obtain the images of the orientation rods, and the centroid coordinate of every rod image was acquired with Matlab software. With the average coordinate value of the rods as the fiducial point, two-dimensional projective transformation coefficient of each image was determined. Projective transformation was then carried out and projective distortion from each original serial image was eliminated. The rectified cross-sectional images were again processed using Photoshop to obtain the image of the first orientation rod, the coordinate value of first rod image was calculated using Matlab software, and the cross-sectional images were cut into images of the same size according to the first rod spatial coordinate, to achieve automatic registration of the serial cross-sectional images. sing Photoshop and Matlab softwares, projective transformation can accurately accomplish the image registration for the serial images with simpler calculation processes and easier computer processing.",

"title": "Quantitative proteomics reveals ELP2 as a regulator to the inhibitory effect of TNF-α on osteoblast differentiation.",
"abstract": "TNF-α, one of the most potent pro-inflammatory cytokines, plays a critical role in inhibition of osteoblast differentiation and bone regeneration in persistent inflammatory microenvironment. To explore the mechanism, quantitative proteomics based on iTRAQ and MRM was employed. The results showed 6 proteins involved in BMP-2 induced osteoblast differentiation inhibition by TNF-α: Periostin, Protein S100-A4, ATPase inhibitor, Cytochrome b5, SERCA3, and ELP2. The altered proteins were involved in molecular transport, tissue development, energy metabolism, and inflammation. One specific protein, ELP2 (STAT3-interacting protein 1, StIP1) up-regulated in the inhibition of osteoblast differentiation by TNF-α was verified to play a critical role in STAT3 pathway. Overexpression or knockdown of ELP2 in C2C12 and MC3T3-E1 cells affected osteoblast differentiation inhibition induced by TNF-α. These results highlight the function of ELP2 in inflammatory microenvironment, ELP2 up-regulation and STAT3 pathway activation may down-regulate BMPR2, then BMP-2 was blocked and osteoblast differentiation inhibited. The protein-expression profile revealed here should offer at least partly new clues to understand the mechanism of osteoblast differentiation inhibition by inflammation.Persistent inflammation is always associated with osteogenesis and affects this balance to reduce bone mass including traumatic open bone fracture, rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), but the cellular mechanisms are not fully elucidated. Tumor necrosis factor-α (TNF-α) is one of the most potent pro-inflammatory cytokines and is known to be a catabolic factor in these inflammatory reaction of diseases. We show for the first time using proteomics methods that in inflammatory microenvironment, osteoblast differentiation will be inhibited by TNF-α induced ELP2 up-regulation and STAT3 pathway activation. Our results are significant since they point to targeting ELP2 activity as a novel therapeutic option to limit the inhibition of osteoblast differentiation by inflammatory microenvironment.",

"abstract": "Whether dynamic or static external fixation is more appropriate for distal radius fractures is still being debated, our aim is to determine the effect of dynamic versus static external fixation for unstable distal radius fractures in terms of postoperative complication, clinical results and radiological outcomes.We selected PubMed, Cochrane Library, EMBASE, BIOSIS, Ovid and the relevant English orthopaedic journals and pooled data from eligible trials including six eligible randomised controlled trials and two comparative studies containing 998 patients comparing dynamic and static external fixation for unstable distal radius fractures to conduct a sub-group analysis according to different periods of follow-up, aiming to summarise the best available evidence.The results showed there was an increased risk for pin-track infection in dynamic external fixation group than that in static external fixation group, however, there was the trend of obtaining better clinical effect towards less malunion in dynamic external fixation group, although the results were not statistically significant. With regard to clinical results, range of motion such as extension, supination and pronation were superior in dynamic external fixation group than that in static external fixation group at 6 weeks postoperatively. And there were the trend of obtaining better clinical effect in dynamic external fixation group towards pronation at one year follow-up and grip strength at six weeks, six months and one year follow-up, although no significant differences were viewed. With regard to radiological outcomes, better clinical result was obtained in terms of radial length in dynamic external fixation group immediately after surgery and at six weeks, one year follow-up postoperatively.The final results show that there are some evidences supporting the use of dynamic external fixation, which may also have practical advantages over static fixation by allowing earlier limb mobility during the fixation period and enabling such patients to maintain their independence. Limitations remain, a cost-effectiveness analysis and DASH-score assessments at all follow-up evaluations should be more carefully considered and reported in a reliable, consistent and standardised manner.",

[Method]The randomized controlled trials(RCT) and quasi-randomized controlled trials(CCT) about reamed or unreamed intramedullary nailing for closed tibial fractures were collected through computer search,manual search and other search methods with the method recommended by Cochrane Collaboration. [Result]This study involved 6 RCT studies,and a total of 1214 cases.The Meta analysis showed that:(1) there were statistical differences between the RTN group and the UTN group.The non-union rate of the RTN group was lower than that of the UTN group(RR = 0.41;95% CI(0.21,,0.78),P= 0.007);(2) The failure rate of the RTN group was lower than that of the UTN group,and the difference was statistically significant(RR = 0.32;95% CI(0.20,0.50),P<0.0001);(3) There was no statistically significant difference between the RTN group and the UTN group in the incidence of postoperative malunion and infection.The relative risk were 0.45(95% CI(0.0.16,1.22),P=0.12) and 0.45(95% CI(0.13,2.16),P= 0.38),respectively. [Conclusion]The research result indicated that,RTN can reduce the non-union rate or implant failure rate of closed tibial fractures compared with the UTN.Therefore,RTN is a better choice.However,due to the limitation of the quality of literature and the number of the samples,the result needs to be further confirmed with the randomized controlled trial of the large multi-center samples.",

"abstract": "Background:In recent years,digital technology has become one of the hottest and most advanced topics in the field of orthopedic surgery and microsurgery,which have achieved remarkable progress in reconstructing the digital model of the bone and joint and developing virtual surgery system.For example,a three-dimensional tissue flap model could be established using digital virtual technology,which,compared with traditional methods,gives a more intuitive and personalized view for the surgeons.Therefore,it is expected to provide more accurate and detailed anatomical data for clinical studies.Objective:To evaluate the application of digital three-dimensional tissue flap in anatomic measurement.Methods:Six adult volunteers underwent contrast-enhanced CT angiography of pelvic and lower limbs by a 64-row multi-slice spiral CT after median cubital vein injection with Ultravist(3.5 ml/s).Two-D images from these data in Dicom format were transformed into computer.Two adult fresh cadaver specimens,one male and one female,were subjected to radiographic CT scanning before and after perfused with lead oxide-gelatine mixture,with collimation of 0.5 mm.Through Amira 4.1(TGS) software,the 2-D images in Dicom format were transformed into the 3-D models of the entire region.Amira 4.1 was used for 3-D reconstruction and 3-D display of gastrocnemius flap and iliac bone flap to observe the main flap artery type,the number of perforator vessels,the diameter of the main and perforator vessels,the tube pedicle length and distribution of anatomical specimens compared with the tissue flap data.Results:The data of the digital flap model complied with that of the skin specimens.The small perforator vessels and the distribution of vascular network could be clearly observed in the model perfused with lead oxide-gelatine mixture.The diameter of blood vessel was larger than the normal one due to the perfusion pressure in the reconstruction model.However,the diameter was smaller by CT angiographic reconstruction.Conclusions:Digital reconstruction technology can visualize directly the tissue flap in 3-D anatomical morphology.It canbe used as a new method for microsurgery and anatomy teaching to overcome the inadequacy of body specimens.Furthermore,it will provide new insight into gross anatomy measurement.",

"abstract": "Objective To systematically evaluate the clinical efficacy and complications of surgical and nonsurgical treatment for patients with acute nondisplaced or minimally displaced scaphoid fractures.Methods Relevant literature on orthopedics was reviewed from Coehrane library,Cochrane database(2011),MEDLINE(January 1966 to October 2011),EMbase(June 1966 to October 2011),CBM(January 1979 to October 2011),PubMed(June 1966 to October 2011),Wanfang database and CQVIP database.Data of randomized controlled trials(RCTs) and quasi-randomized controlled trials(Quasi-RCTs) on treatment for acute nondisplaced or minimally displaced scaphoid fractures were collected.Metaanalysis was conducted by using the Cachrane Collaboration′s RevMan 5.1 software.Results Nine RCTs involving 559 patients were performed in the study.The meta analysis revealed that the surgical group had shorter time from surgery to going back to work[SMD=-2.06,95%CI(-3.46,-0.67),P=0.004],faster fracture recovery [SMD=-5.88,95%CI(-9.23,-2.54),P=0.0006],but the rate of osteoarthritis of the scaphotrapezial joint was higher than nonsurgical group[RR=3.72,95%CI(1.61,8.63),P=0.002].No significant differences were found between the two groups in terms of the grip strength,wrist motion,DASH-score and PRWE-score,and incidence rates of non-union and osteoar-thritis of the radiocarpal joint.Conclusion Compared with nonsurgical group,patients in the surgical group can go back to work earlier and recover faster after adult nondisplaced or minimally displaced scaphoid fractures,but the rate of osteoarthritis of the scaphotrapezial joint is higher.Owing to the limitations of the study,large-scale randomized controlled trials are required for more precise conclusions.",

"title": "A novel resorbable strontium-containing α-calcium sulfate hemihydrate bone substitute: a preparation and preliminary study.",
"abstract": "Distraction osteogenesis after aggrieved bone segment resections is promising in the treatment of bone tumors and osteomyelitis. However, there is ambiguity with regard to the optimal choice of bone substitute, with biodegradability and excellent bone repair performance constituting key requirements. The purpose of this study was to develop a novel resorbable strontium-containing alpha-calcium sulfate hemihydrate (Sr-CaS) bone substitute to provide an alternative option for surgeons that better meets these requirements. The Sr-CaS was prepared using co-precipitation and hydrothermal methods and analyzed using x-ray diffraction (XRD), Fourier transform infrared (FTIR) scanning and thermogravimetric differential scanning calorimeter (TG-DSC) patterns. Cytotoxicity by tetrazolium bromide (MTT), sub-acute toxicity and hemolysis tests were performed to assess the initial biocompatibility of the new bone substitute. Radiographic analysis, micro-CT measurements and histological observation were used to evaluate the bone repair ability in rat tibia bone defects. The XRD and FTIR patterns of Sr-CaS were both very similar to CaS and the product had comparable characteristics similar to alpha-CaS as demonstrated by TG-DSC. Cytotoxicity of the substitute was class 1 (no cytotoxicity) and hemolysis was 4.3% (no hemolysis). Sub-acute toxicity was not seen after a 14 day evaluation. The substitute was radio-opaque. The empty group exhibited the lowest levels of both bone mineral densities (BMD) and bone volume/total volume (BV/TV) of the defects when compared to all other groups. The two Sr-CaS groups resulted in significantly greater BMDs and BV/TV of the defect compared to the CaS only group. However, there was no significant difference between the 5% and 10% Sr-CaS groups. The Sr-CaS was resorbable with satisfactory biocompatibility. The doped strontium ions enhanced the bone repair performance of CaS in a rat model and the new substitute demonstrated promising results for clinical use.",

"abstract": "The goal of this study was to compare the outcomes of unstable trochanteric fractures treated with the InterTan nail (Smith & Nephew, Memphis, Tennessee) and the Proximal Femoral Nail Antirotation (PFNA-II) (Synthes, Solothurn, Switzerland). A total of 132 consecutive patients with unstable trochanteric fractures of the femur were enrolled in the study. The only intervention was InterTan nail or PFNA-II fixation of the unstable trochanteric fractures. Follow-up occurred at 1, 3, 6, and 12 months postoperatively and yearly thereafter. Radiographs were obtained at each follow-up, and all implant position changes, complications, and fixation failures were recorded. A total of 113 patients meeting the criteria were evaluated at a mean last follow-up of 18.36 months (range, 12-30 months). Intraoperative complications and length of hospital stay were comparable between the groups. Patients treated with the PFNA-II experienced shorter fluoroscopy and operative times, less intraoperative blood loss, and less femoral neck shortening. The incidence of thigh pain was significantly higher in the PFNA-II group (30.4%) than in the InterTan group (10.3%) (P=.001). No statistically significant differences existed in general complications, local complications, walking ability, Harris Hip Scores, or hip range of motion at final follow-up.",

"abstract": "Eucommia ulmoides Oliv. bark (EU) is a common traditional Chinese herbal medicine for treatment of osteoarthritis (OA), but its therapeutic effect on OA and the underlying mechanisms have not been fully clarified. Our previous study showed that Eucommia ulmoides Oliv. bark aqueous extract (EUE) had a protective effect on cartilage, and this study was aimed to investigate the anti-osteoarthritis effect and mechanisms of EUE in a rat model of osteoarthritis.Thirty-two 5-week-old specific pathogen-free Sprague-Dawley rats which were randomized into four even groups (n=8). Group A received sham operation while the OA model was established using the modified Hulth technique in groups B, C and D. For eight weeks after operation, in addition to routine feeding, group A received gavage with deionized water, group B with deionized water, group C with 1.35 g/kg/day EUE, and group D with 2.7 g/kg/day EUE. Eight weeks postoperatively, all of the animals were euthanized for radiological, gross and histopathological observations to evaluate the effect of EUE on OA and to determine its potential mechanisms.Radiological and histopathological observations showed that the articular degenerative changes were significantly more alleviated in groups C and D than in group B, while there were no obviously degenerative manifestations in group A. Mankin׳s scores in groups C and D were significantly lower than in group B (P<0.01). The severity of OA was significantly less in group D than in group C (P<0.01). The IL-1β and IL-6 contents in serum and MMP-3 secretion in articular cartilage were significantly lower in groups C and D than those in group B (P<0.01), and significantly lower in group D than those in group C (P<0.01). Compared with group B, phosphorylated Akt was significantly down-regulated in groups C and D.EUE may inhibit the progression of osteoarthritis by inhibiting the PI3K/Akt pathway to delay cartilage degeneration, reduce inflammatory cytokines and prevent MMP-3 secretion. Therefore, EU is a potential therapeutic agent for OA, but its efficacy is limited.",

"abstract": "Purpose: The aim of this study was to establish a platform for future investigation of the mechanisms mediating the repair of tissue engineering bone (TEB) in a large segmental femur defect model. Methods: A large segmental femur defect (5 mm) model was developed by microsurgery in red fluorescent protein (RFP) transgenic mice. The defects were repaired with TEB in situ, composed of a beta-tricalcium phosphate scaffold and preseeded with mesenchymal stem cells (MSCs) derived from enhanced green fluorescent protein transgenic mice (eGFP-MSCs). X-ray analysis, pathological observation, and quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) were used to examine the femur defects. Results: Three months postoperation, X-ray analysis revealed good prognoses in mice treated with TEB. Complete connection of the callus bone was observed by gross anatomy. Pathological observation showed recanalization of the bone marrow under confocal and fluorescent microscopy. Histological and qRT-PCR analyses showed that donor and recipient cells were actively involved in the bone repair process. Conclusions: We established a large segmental bone defect TEB repair model with dual fluorescent chimeric transgenic mice to serve as a platform for studying the mechanisms of TEB healing in vivo and provide a bases for further clinical applications.",

Operative treatments include open surgery and percutaneous minimally invasive surgery. Compared with non-operative treatment, operative treatment can effectively reduce the re-rupture incidence, but it had higher complication incidences of wound infection and nerve injury. Although early functional rehabilitation during non-operative treatment could reduce the re-rutpture incidence, there is no consistent orthopaedic device and guideline for functional rehabilitation.Both operative and non-operative treatments have advantages and disadvantages for the treatment of acute Achilles tendon rupture. No consistent conclusion is arrived regarding functional recovery. Future studies should explore the strategy of early functional rehabilitation during non-operative treatment and its mechanism of promoting tendon healing.",

"abstract": "Background: The treatment of soft tissue defect of ankle is a challenge for orthopaedic surgeon, and skin flap transplantation has been indispensable. Objective: The aim of this study is to evaluate the surgical technique and clinical significance of the therapy for ankle soft tissue defect with two different free perforator flaps. Methods: Free perforator flap transplantations were performed in 30 patients with soft tissue defect and exposed bone of the ankle between August 2006 and April 2012. There were 24 males and 6 females aged from 3~52 years. The wounds were covered by vacuum sealing drainage (VSD) before operation. The size of the wound varied from 6 cm×8 cm to 11 cm×23 cm. Of them, 12 cases were repaired by thoraco-umbilical flap and 18 cases were repaired by anterolateral thigh flap. Results: All the 30 flaps survived. The mean duration of follow-up was 11.0 months (range, 3 to 24 months). The appear- ance of the flaps was satisfactory, with 10 to 22 mm in 2-PD. The sensation percentage beyond S2was 58.3% and 68.8% for thoraco-umbilical flap and anterolateral thigh flap transplantations, respectively. Conclusions: Both free anterolateral thigh perforator flap and free thoraco-umbilical perforator flap are suitable for the soft tissue defect of ankle. Perforator flap can decrease secondary orthopaedic surgery. VSD can significantly decrease the infec- tion of the perforator flaps.",

"title": "Detection of daytime arctic clouds using MISR and MODIS data",
"abstract": "Expert labels were used to evaluate arctic cloud detection accuracies of several methods based on MISR angular radiances and MODIS spectral radiances. The accuracy of cloud detections was evaluated relative to 5.086 million expert labels applied to 7.114 million 1.1-km resolution pixels with valid radiances from 57 scenes. The accuracy of the MODIS operational cloud mask was 90.72% for the 32 partly cloudy scenes and 93.37% for the 25 completely clear and overcast scenes. An automated, simple threshold algorithm based on three features extracted from MISR radiances and the MODIS operational cloud mask agreed with each other for 74.91% of the pixels in the 32 partly cloudy scenes and 78.44% of the pixels in the 25 completely clear and overcast scenes. These subsets of pixels had, relative to the expert labels, classification accuracies of 96.53% for the 32 partly cloudy scenes and 99.05% for the 25 completely clear and overcast scenes. Fisher's quadratic discriminate analysis (QDA) trained on expert labels from the 32 partly cloud scenes was applied to MISR radiances, three features based on MISR radiances, MODIS radiances, and the six features of the MODIS operational cloud mask with accuracies ranging from 87.51% to 96.43%. Accuracies increased to about 97% when QDA with expert labels was applied to combined radiances or features from both MISR and MODIS. Operational QDA-based classifiers were developed using as training labels those pixels for which the MISR automated, simple threshold and MODIS operational cloud mask algorithms agreed. Training the QDA classifier on these automatic labels using MISR radiances, three features based on MISR radiances, MODIS radiances, and the six features of the MODIS operational cloud mask led to accuracies ranging from 85.23% to 93.62% for the 32 partly cloudy scenes. Classification accuracies increased to 93.74% (93.40%) when combined MISR and MODIS radiances (features) were used. The highest accuracy attained with any operational algorithm tested on all 57 scenes was 94.51%. These results suggest that both MISR and MODIS radiances are sufficient for cloud detection in daytime polar regions.",

In such settings, it is known that a global maximum of the MLE based on $n$ samples can have a non-standard $n^{-1/4}$ rate of convergence. How does the EM algorithm behave in such settings? Focusing on the simple setting of a two-component mixture fit to a multivariate Gaussian distribution, we study the behavior of the EM algorithm both when the mixture weights are different (unbalanced case), and are equal (balanced case). Our analysis reveals a sharp distinction between these cases: in the former, the EM algorithm converges geometrically to a point at Euclidean distance $O((d/n)^{1/2})$ from the true parameter, whereas in the latter case, the convergence rate is exponentially slower, and the fixed point has a much lower $O((d/n)^{1/4})$ accuracy. The slower convergence in the balanced over-fitted case arises from the singularity of the Fisher information matrix. Analysis of this singular case requires the introduction of some novel analysis techniques, in particular we make use of a careful form of localization in the associated empirical process, and develop a recursive argument to progressively sharpen the statistical rate.",

"title": "Superheat: An R Package for Creating Beautiful and Extendable Heatmaps for Visualizing Complex Data",
"abstract": "The technological advancements of the modern era have enabled the collection of huge amounts of data in science and beyond. Extracting useful information from such massive datasets is an ongoing challenge as traditional data visualization tools typically do not scale well in high-dimensional settings. An existing visualization technique that is particularly well suited to visualizing large datasets is the heatmap. Although heatmaps are extremely popular in fields such as bioinformatics, they remain a severely underutilized visualization tool in modern data analysis. This paper introduces superheat, a new R package that provides an extremely flexible and customizable platform for visualizing complex datasets. Superheat produces attractive and extendable heatmaps to which the user can add a response variable as a scatterplot, model results as boxplots, correlation information as barplots, and more. The goal of this paper is two-fold: (1) to demonstrate the potential of the heatmap as a core visualization method for a range of data types, and (2) to highlight the customizability and ease of implementation of the superheat R package for creating beautiful and extendable heatmaps. The capabilities and fundamental applicability of the superheat package will be explored via three reproducible case studies, each based on publicly available data sources.",

"title": "Network Tomography: Recent Developments",
"abstract": "Today's Internet is a massive, distributed network which continues to explode in size as e- commerce and related activities grow. The heterogeneous and largely unregulated structure of the Internet renders tasks such as dynamic routing, optimized service provision, service level verification, and detection of anomalous/malicious behavior extremely challenging. The problem is compounded by the fact that one cannot rely on the cooperation of individual servers and routers to aid in the collection of network traffic measurements vital for these tasks. In many ways, network monitoring and inference problems bear a strong resemblance to other \"inverse problems\" in which key aspects of a system are not directly observable. Familiar signal processing or statistical problems such as tomographic image reconstruction and phylogenetic tree identification have interesting connections to those arising in networking. This article introduces network tomography, a new field which we believe will benefit greatly from the wealth of statistical theory and algorithms. It focuses especially on recent developments in the field including the application of pseudolikelihood methods and tree estimation formulations.",

"abstract": "Lasso is a regularization method for parameter estimation in linear models. It optimizes the model parameters with respect to a loss function subject to model complexities. This paper explores the use of lasso for statistical language modeling for text input. Owing to the very large number of parameters, directly optimizing the penalized lasso loss function is impossible. Therefore, we investigate two approximation methods, the boosted lasso (BLasso) and the forward stagewise linear regression (FSLR). Both methods, when used with the exponential loss function, bear strong resemblance to the boosting algorithm which has been used as a discriminative training method for language modeling. Evaluations on the task of Japanese text input show that BLasso is able to produce the best approximation to the lasso solution, and leads to a significant improvement, in terms of character error rate, over boosting and the traditional maximum likelihood estimation.",

We propose a new random walk for this purpose, which we refer to as the Vaidya walk, since it is based on the volumetric-logarithmic barrier introduced by Vaidya in the context of interior point methods for optimization. We show that the Vaidya walk mixes in significantly fewer steps compared to the Dikin walk, a random walk previously studied by Kannan and Narayanan. In particular, we prove that for a polytope in R-d defined by n constraints, the Vaidya walk mixes in O (root n/d) fewer steps than the Dikin walk. The per iteration cost for our method is at most twice that of the Dikin walk, and hence the speed up is significant for polytopes with n >> d. Furthermore, the algorithm is also faster than the Ball walk and Hit-and-Run for a large family of polytopes. We illustrate the speed-up of the Vaidya walk over the Dikin walk via several numerical examples and discuss possible new and faster algorithms for sampling from polytopes.",

"title": "Stability-driven nonnegative matrix factorization to interpret spatial gene expression and build local gene networks",
"abstract": "Spatial gene expression patterns enable the detection of local covariability and are extremely useful for identifying local gene interactions during normal development. The abundance of spatial expression data in recent years has led to the modeling and analysis of regulatory networks. The inherent complexity of such data makes it a challenge to extract biological information. We developed staNMF, a method that combines a scalable implementation of nonnegative matrix factorization (NMF) with a new stability-driven model selection criterion. When applied to a set of Drosophila early embryonic spatial gene expression images, one of the largest datasets of its kind, staNMF identified 21 principal patterns (PP). Providing a compact yet biologically interpretable representation of Drosophila expression patterns, PP are comparable to a fate map generated experimentally by laser ablation and show exceptional promise as a data-driven alternative to manual annotations. Our analysis mapped genes to cell-fate programs and assigned putative biological roles to uncharacterized genes. Finally, we used the PP to generate local transcription factor regulatory networks. Spatially local correlation networks were constructed for six PP that span along the embryonic anterior–posterior axis. Using a two-tail 5% cutoff on correlation, we reproduced 10 of the 11 links in the well-studied gap gene network. The performance of PP with the Drosophila data suggests that staNMF provides informative decompositions and constitutes a useful computational lens through which to extract biological insight from complex and often noisy gene expression data.",

"abstract": "Since its early use in least squares regression problems, the l1-penalization\nframework for variable selection has been employed in conjunction with a wide\nrange of loss functions encompassing regression, classification and survival\nanalysis. While a well developed theory exists for the l1-penalized least\nsquares estimates, few results concern the behavior of l1-penalized estimates\nfor general loss functions. In this paper, we derive two results concerning\npenalized estimates for a wide array of penalty and loss functions. Our first\nresult characterizes the asymptotic distribution of penalized parametric\nM-estimators under mild conditions on the loss and penalty functions in the\nclassical setting (fixed-p-large-n). Our second result explicits necessary and\nsufficient generalized irrepresentability (GI) conditions for l1-penalized\nparametric M-estimates to consistently select the components of a model\n(sparsistency) as well as their sign (sign consistency). In general, the GI\nconditions depend on the Hessian of the risk function at the true value of the\nunknown parameter. Under Gaussian predictors, we obtain a set of conditions\nunder which the GI conditions can be re-expressed solely in terms of the second\nmoment of the predictors. We apply our theory to contrast l1-penalized SVM and\nlogistic regression classifiers and find conditions under which they have the\nsame behavior in terms of their model selection consistency (sparsistency and\nsign consistency). Finally, we provide simulation evidence for the theory based\non these classification examples.",

"title": "Estimation Stability with Cross Validation (ESCV)",
"abstract": " Cross-validation (CV) is often used to select the regularization parameter in high dimensional problems. However, when applied to the sparse modeling method Lasso, CV leads to models that are unstable in high-dimensions, and consequently not suited for reliable interpretation. In this paper, we propose a model-free criterion ESCV based on a new estimation stability (ES) metric and CV. Our proposed ESCV finds a locally ES-optimal model smaller than the CV choice so that the it fits the data and also enjoys estimation stability property. We demonstrate that ESCV is an effective alternative to CV at a similar easily parallelizable computational cost. In particular, we compare the two approaches with respect to several performance measures when applied to the Lasso on both simulated and real data sets. For dependent predictors common in practice, our main finding is that, ESCV cuts down false positive rates often by a large margin, while sacrificing little of true positive rates. ESCV usually outperforms CV in terms of parameter estimation while giving similar performance as CV in terms of prediction. For the two real data sets from neuroscience and cell biology, the models found by ESCV are less than half of the model sizes by CV. Judged based on subject knowledge, they are more plausible than those by CV as well. We also discuss some regularization parameter alignment issues that come up in both approaches. ",

Treating a kernel function K(x, y) as \"light\" and the sampled data as \"substance\", the spectrum of their interaction (eigenvalues and eigenvectors of the kernel matrix K) unveils certain aspects of the underlying parametric distribution p, such as the parameters of a Gaussian mixture. Our approach extends the intuitions and analyses underlying the existing spectral techniques, such as spectral clustering and Kernel Principal Components Analysis (KPCA). We construct algorithms to estimate parameters of Gaussian mixture models, including the number of mixture components, their means and covariance matrices, which are important in many practical applications.

"abstract": "Detection of clouds in satellite-generated radiance images, including those from MODIS, is an important first step in many applications of these data. In this paper we apply spectral unmixing to this problem with the aim of estimating subpixel cloud fractions, as opposed to identification only of whether or not a pixel radiance contains cloud contributions. We formulate the spectral unmixing approach in terms of multiple-kernel learning (MKL). To this end we propose a MKL-based unmixing algorithm that drives a multiple-kernel description of cloud, enabling estimation of sub-pixel cloud fractions. This approach is based on supervised learning. We generate training and testing samples by using CloudSat and CALIPSO data to compute cloud fractions within individual MODIS pixels. Results of our study on limited data (1875 training and testing MODIS pixels along with their CloudSat and CALIPSO based sub-pixel cloud fractions) show that the proposed algorithm can effectively estimate sub-pixel MODIS cloud fraction and outperforms support vector machine (SVM) in terms of estimation performance.",

While this is an effective estimation strategy, it tempts the practitioner to ignore the role of the stimulus and the meaning of mutual information. We show here that as the number of trials increases indefinitely, the direct (or plug-in) estimate of marginal entropy converges (with probability 1) to the entropy of the time-averaged conditional distribution of the response, and the direct estimate of the conditional entropy converges to the time-averaged entropy of the conditional distribution of the response. Under joint stationarity and ergodicity of the response and stimulus, the difference of these quantities converges to the mutual information. When the stimulus is deterministic or nonstationary the direct estimate of information no longer estimates mutual information, which is no longer meaningful, but it remains a measure of variability of the response distribution across time.",

"abstract": " Directed graphs have asymmetric connections, yet the current graph clustering methodologies cannot identify the potentially global structure of these asymmetries. We give a spectral algorithm called di-sim that builds on a dual measure of similarity that correspond to how a node (i) sends and (ii) receives edges. Using di-sim, we analyze the global asymmetries in the networks of Enron emails, political blogs, and the c elegans neural connectome. In each example, a small subset of nodes have persistent asymmetries; these nodes send edges with one cluster, but receive edges with another cluster. Previous approaches would have assigned these asymmetric nodes to only one cluster, failing to identify their sending/receiving asymmetries. Regularization and \"projection\" are two steps of di-sim that are essential for spectral clustering algorithms to work in practice. The theoretical results show that these steps make the algorithm weakly consistent under the degree corrected Stochastic co-Blockmodel, a model that generalizes the Stochastic Blockmodel to allow for both (i) degree heterogeneity and (ii) the global asymmetries that we intend to detect. The theoretical results make no assumptions on the smallest degree nodes. Instead, the theorem requires that the average degree grows sufficiently fast and that the weak consistency only applies to the subset of the nodes with sufficiently large leverage scores. The results results also apply to bipartite graphs. ",

"abstract": "Machine-learning models have demonstrated great success in learning complex patterns that enable them to make predictions about unobserved data. In addition to using models for prediction, the ability to interpret what a model has learned is receiving an increasing amount of attention. However, this increased focus has led to considerable confusion about the notion of interpretability. In particular, it is unclear how the wide array of proposed interpretation methods are related and what common concepts can be used to evaluate them. We aim to address these concerns by defining interpretability in the context of machine learning and introducing the predictive, descriptive, relevant (PDR) framework for discussing interpretations. The PDR framework provides 3 overarching desiderata for evaluation: predictive accuracy, descriptive accuracy, and relevancy, with relevancy judged relative to a human audience. Moreover, to help manage the deluge of interpretation methods, we introduce a categorization of existing techniques into model-based and post hoc categories, with subgroups including sparsity, modularity, and simulatability. To demonstrate how practitioners can use the PDR framework to evaluate and understand interpretations, we provide numerous real-world examples. These examples highlight the often underappreciated role played by human audiences in discussions of interpretability. Finally, based on our framework, we discuss limitations of existing methods and directions for future work. We hope that this work will provide a common vocabulary that will make it easier for both practitioners and researchers to discuss and choose from the full range of interpretation methods.",

"abstract": "Consider the standard linear regression model y = X beta* + w, where y is an element of R-n is an observation vector, X is an element of R-nxd is a measurement matrix, beta* is an element of R-d is the unknown regression vector, and w similar to N(0, sigma I-2) is additive Gaussian noise. This paper determines sharp minimax rates of convergence for estimation of beta* in l(2) norm, assuming that beta* belongs to a weak l(q)-ball B-q (R-q) for some q is an element of [0, 1]. We show that under suitable regularity conditions on the design matrix X, the minimax error in squared l(2)-norm scales as R-q(logd/n)(1-q/2). In addition, we provide lower bounds on rates of convergence for general l(p) norm (for all p is an element of [1, + infinity], p not equal q). Our proofs of the lower bounds are information-theoretic in nature, based on Fano's inequality and results on the metric entropy of the balls B-q (R-q). Matching upper bounds are derived by direct analysis of the solution to an optimization algorithm over We prove that the conditions on X required by optimal algorithms are satisfied with high probability by broad classes of non-i.i.d. Gaussian random matrices, for which RIP or other sparse eigenvalue conditions are violated. For q = 0, l(1)-based methods (Lasso and Dantzig selector) achieve the minimax optimal rates in l(2) error, but require stronger regularity conditions on the design than the non-convex optimization algorithm used to determine the minimax upper bounds.",

"abstract": "Many statistical machine learning algorithms minimize either an empirical loss function as in AdaBoost, or a penalized empirical loss as in Lasso or SVM. A single regularization tuning parameter controls the trade-off between fidelity to the data and generalizability, or equivalently between bias and variance. When this tuning parameter changes, a regularization \"path\" of solutions to the minimization problem is generated, and the whole path is needed to select a tuning parameter to optimize the prediction or interpretation performance. Algorithms such as homotopy-Lasso or LARS-Lasso and Forward Stagewise Fitting (FSF) (aka e-Boosting) are of great interest because of their resulted sparse models for interpretation in addition to prediction. In this paper, we propose the BLasso algorithm that ties the FSF (e-Boosting) algorithm with the Lasso method that minimizes the L1 penalized L2 loss. BLasso is derived as a coordinate descent method with a fixed stepsize applied to the general Lasso loss function (L1 penalized convex loss). It consists of both a forward step and a backward step. The forward step is similar to e-Boosting or FSF, but the backward step is new and revises the FSF (or e-Boosting) path to approximate the Lasso path. In the cases of a finite number of base learners and a bounded Hessian of the loss function, the BLasso path is shown to converge to the Lasso path when the stepsize goes to zero. For cases with a larger number of base learners than the sample size and when the true model is sparse, our simulations indicate that the BLasso model estimates are sparser than those from FSF with comparable or slightly better prediction performance, and that the the discrete stepsize of BLasso and FSF has an additional regularization effect in terms of prediction and sparsity. Moreover, we introduce the Generalized BLasso algorithm to minimize a general convex loss penalized by a general convex function. Since the (Generalized) BLasso relies only on differences not derivatives, we conclude that it provides a class of simple and easy-to-implement algorithms for tracing the regularization or solution paths of penalized minimization problems.",

"title": "Spectral clustering and the high-dimensional Stochastic Block Model",
"abstract": "Networks or graphs can easily represent a diverse set of data sources that\nare characterized by interacting units or actors. Social networks, representing\npeople who communicate with each other, are one example. Communities or\nclusters of highly connected actors form an essential feature in the structure\nof several empirical networks. Spectral clustering is a popular and\ncomputationally feasible method to discover these communities. The Stochastic\nBlock Model (Holland et al., 1983) is a social network model with well defined\ncommunities; each node is a member of one community. For a network generated\nfrom the Stochastic Block Model, we bound the number of nodes \"misclustered\" by\nspectral clustering. The asymptotic results in this paper are the first\nclustering results that allow the number of clusters in the model to grow with\nthe number of nodes, hence the name high-dimensional. In order to study\nspectral clustering under the Stochastic Block Model, we first show that under\nthe more general latent space model, the eigenvectors of the normalized graph\nLaplacian asymptotically converge to the eigenvectors of a \"population\"\nnormalized graph Laplacian. Aside from the implication for spectral clustering,\nthis provides insight into a graph visualization technique. Our method of\nstudying the eigenvectors of random matrices is original.",

"title": "Metalearners for estimating heterogeneous treatment effects using machine learning.",
"abstract": "There is growing interest in estimating and analyzing heterogeneous treatment effects in experimental and observational studies. We describe a number of metaalgorithms that can take advantage of any supervised learning or regression method in machine learning and statistics to estimate the conditional average treatment effect (CATE) function. Metaalgorithms build on base algorithms-such as random forests (RFs), Bayesian additive regression trees (BARTs), or neural networks-to estimate the CATE, a function that the base algorithms are not designed to estimate directly. We introduce a metaalgorithm, the X-learner, that is provably efficient when the number of units in one treatment group is much larger than in the other and can exploit structural properties of the CATE function. For example, if the CATE function is linear and the response functions in treatment and control are Lipschitz-continuous, the X-learner can still achieve the parametric rate under regularity conditions. We then introduce versions of the X-learner that use RF and BART as base learners. In extensive simulation studies, the X-learner performs favorably, although none of the metalearners is uniformly the best. In two persuasion field experiments from political science, we demonstrate how our X-learner can be used to target treatment regimes and to shed light on underlying mechanisms. A software package is provided that implements our methods.",

"title": "Iterative random forests to discover predictive and stable high-order interactions.",
"abstract": "Genomics has revolutionized biology, enabling the interrogation of whole transcriptomes, genome-wide binding sites for proteins, and many other molecular processes. However, individual genomic assays measure elements that interact in vivo as components of larger molecular machines. Understanding how these high-order interactions drive gene expression presents a substantial statistical challenge. Building on random forests (RFs) and random intersection trees (RITs) and through extensive, biologically inspired simulations, we developed the iterative random forest algorithm (iRF). iRF trains a feature-weighted ensemble of decision trees to detect stable, high-order interactions with the same order of computational cost as the RF. We demonstrate the utility of iRF for high-order interaction discovery in two prediction problems: enhancer activity in the early embryo and alternative splicing of primary transcripts in human-derived cell lines. In , among the 20 pairwise transcription factor interactions iRF identifies as stable (returned in more than half of bootstrap replicates), 80% have been previously reported as physical interactions. Moreover, third-order interactions, e.g., between (), (), and (), suggest high-order relationships that are candidates for follow-up experiments. In human-derived cells, iRF rediscovered a central role of H3K36me3 in chromatin-mediated splicing regulation and identified interesting fifth- and sixth-order interactions, indicative of multivalent nucleosomes with specific roles in splicing regulation. By decoupling the order of interactions from the computational cost of identification, iRF opens additional avenues of inquiry into the molecular mechanisms underlying genome biology.",

"abstract": "The driving force behind the recent success of LSTMs has been their ability to learn complex and non-linear relationships. Consequently, our inability to describe these relationships has led to LSTMs being characterized as black boxes. To this end, we introduce contextual decomposition (CD), an interpretation algorithm for analysing individual predictions made by standard LSTMs, without any changes to the underlying model. By decomposing the output of a LSTM, CD captures the contributions of combinations of words or variables to the final prediction of an LSTM. On the task of sentiment analysis with the Yelp and SST data sets, we show that CD is able to reliably identify words and phrases of contrasting sentiment, and how they are combined to yield the LSTMu0027s final prediction. Using the phrase-level labels in SST, we also demonstrate that CD is able to successfully extract positive and negative negations from an LSTM, something which has not previously been done.",

"title": "A hierarchical Bayesian approach for aerosol retrieval using MISR data",
"abstract": "Atmospheric aerosols can cause serious damage to human health and reduce life expectancy. Using the radiances observed by NASA's Multi-angle Imaging SpectroRadiometer (MISR), the current MISR operational algorithm retrieves aerosol optical depth (AOD) at 17.6 km resolution. A systematic study of aerosols and their impact on public health, especially in highly populated urban areas, requires finerresolution estimates ofAOD's spatial distribution.We embedMISR's operationalweighted least squares criterion and its forward calculations for AOD retrievals in a likelihood framework and further expand into a hierarchical Bayesian model to adapt to finer spatial resolution of 4.4 km. To take advantage of AOD's spatial smoothness, our method borrows strength from data at neighboring areas by postulating a Gaussian Markov random field prior for AOD. Our model considers AOD and aerosol mixing vectors as continuous variables, whose inference is carried out using Metropolis-within-Gibbs sampling methods. Retrieval uncertainties are quantified by posterior variabilities. We also develop a parallel Markov chain Monte Carlo (MCMC) algorithm to improve computational efficiency. We assess our retrieval performance using ground-based measurements from the AErosol RObotic NETwork (AERONET) and satellite images from Google Earth. Based on case studies in the greater Beijing area, China, we show that 4.4 km resolution can improve both the accuracy and coverage of remotely sensed aerosol retrievals, as well as our understanding of the spatial and seasonal behaviors of aerosols. This is particularly important during high-AOD events, which often indicate severe air pollution. © 2013 American Statistical Association.",

"title": "Statistical guarantees for the EM algorithm: From population to sample-based analysis",
"abstract": "The EM algorithm is a widely used tool in maximum-likelihood estimation in incomplete data problems. Existing theoretical work has focused on conditions under which the iterates or likelihood values converge, and the associated rates of convergence. Such guarantees do not distinguish whether the ultimate fixed point is a near global optimum or a bad local optimum of the sample likelihood, nor do they relate the obtained fixed point to the global optima of the idealized population likelihood (obtained in the limit of infinite data). This paper develops a theoretical framework for quantifying when and how quickly EM-type iterates converge to a small neighborhood of a given global optimum of the population likelihood. For correctly specified models, such a characterization yields rigorous guarantees on the performance of certain two-stage estimators in which a suitable initial pilot estimator is refined with iterations of the EM algorithm. Our analysis is divided into two parts: a treatment of the EM and first-order EM algorithms at the population level, followed by results that apply to these algorithms on a finite set of samples. Our conditions allow for a characterization of the region of convergence of EM-type iterates to a given population fixed point, that is, the region of the parameter space over which convergence is guaranteed to a point within a small neighborhood of the specified population fixed point. We verify our conditions and give tight characterizations of the region of convergence for three canonical problems of interest: symmetric mixture of two Gaussians, symmetric mixture of two regressions and linear regression with covariates missing completely at random.",

"abstract": "The performance of the Lasso is well understood under the assumptions of the standard sparse linear model with homoscedastic noise. However, in several applications, the standard model does not describe the important features of the data. This paper examines how the Lasso performs on a non-standard model that is motivated by medical imaging applications. In these applications, the variance of the noise scales linearly with the expectation of the observation. Like all heteroscedastic models, the noise terms in this Poisson-like model are not independent of the design matrix. Under a sparse Poisson-like model for the high-dimension regime that allows the number of predictors (p) ≫ sample size (n), we give necessary and sufficient conditions for the sign consistency of the Lasso estimate. Simulations reveal that the Lasso performs equally well in terms of model selection performance on both Poisson-like data and homoscedastic data (with properly scaled noise variance), across a range of parameterizations.",

"title": "THE COMPOSITE ABSOLUTE PENALTIES FAMILY FOR GROUPED AND HIERARCHICAL VARIABLE SELECTION1",
"abstract": "Extracting useful information from high-dimensional data is an important focus of today's statistical research and practice. Penalized loss function minimization has been shown to be effective for this task both theoretically and empirically. With the virtues of both regularization and sparsity, the L-1-penalized squared error minimization method Lasso has been popular in regression models and beyond. In this paper, we combine different norms including L-1 to form an intelligent penalty in order to add side information to the fitting of a regression or classification model to obtain reasonable estimates. Specifically, we introduce the Composite Absolute Penalties (CAP) family, which allows given grouping and hierarchical relationships between the predictors to be expressed. CAP penalties are built by defining groups and combining the properties of norm penalties at the across-group and within-group levels. Grouped selection occurs for nonoverlapping groups. Hierarchical variable selection is reached by defining groups with particular overlapping patterns. We propose using the BLASSO and cross-validation to compute CAP estimates in general. For a subfamily of CAP estimates involving only the L-1 and L-proportional to norms, we introduce the iCAP algorithm to trace the entire regularization path for the grouped selection problem. Within this subfamily, unbiased estimates of the degrees of freedom (df) are derived so that the regularization parameter is selected without cross-validation. CAP is shown to improve on the predictive performance of the LASSO in a series of simulated experiments, including cases with p >> n and possibly mis-specified groupings. When the complexity of a model is properly calculated, iCAP is seen to be parsimonious in the experiments.",

"title": "Maximum pseudo likelihood estimation in network tomography",
"abstract": "Network monitoring and diagnosis are key to improving network performance. The difficulties of performance monitoring lie in today's fast growing Internet, accompanied by increasingly heterogeneous and unregulated structures. Moreover, these tasks become even harder since one cannot rely on the collaboration of individual routers and servers to measure network traffic directly. Even though the aggregative nature of possible network measurements gives rise to inverse problems, existing methods for solving inverse problems are usually computationally intractable or statistically inefficient. A pseudo likelihood approach is proposed to solve a group of network tomography problems. The basic idea of pseudo likelihood is to form simple subproblems and ignore the dependences among the subproblems to form a product likelihood of the subproblems. As a result, this approach keeps a good balance between the computational complexity and the statistical efficiency of the parameter estimation. Some statistical properties of the pseudo likelihood estimator, such as consistency and asymptotic normality, are established. A pseudo expectation-maximization (EM) algorithm is developed to maximize the pseudo log-likelihood function. Two examples, with simulated or real data, are used to illustrate the pseudo likelihood proposal: 1) inference of the internal link delay distributions through multicast end-to-end measurements; 2) origin-destination matrix estimation through link traffic counts.",

"title": "Sparsity and model selection through convex penalties: structured selection, covariance selection and some theory",
"abstract": "High-dimensional data sets requires model selection methods capable of controlling model complexity and goodness of fit to the observed data. Such problems constitute a natural setting where to apply penalized empirical risk minimization. Ideally, a model should be interpretable and easy to compute. Sparsity in a parameter space is a proxy for interpretability and is traditionally enforced in statistics by penalizing the dimensionality of the parameter space. Such penalties lead to interpretable models but involve a combinatorial search and are thus computationally costly to obtain, obtained by penalizing the ℓ 1-norm of the fitted parameters. In the first article of this thesis, we present a simulation based comparison of two traditional approaches to tackle the computational burden of dimensionality based penalties: the more traditional greedy algorithms and the more recent convex relaxation methods. We conclude that convex relaxation yields estimates that are better in terms of predictive performance and comparable in terms of parameter selection provided the appropriate criterion is used for each application. Then, we introduce the family of Composite Absolute Penalties (CAP). Penalty functions in this family are capable of performing grouped and hierarchical selection. Building upon convexity of CAP penalties, algorithms for efficiently computing the CAP estimates for different levels of penalization and methods for choosing an appropriate level of penalization are proposed. The predictive and parsimony gains of employing CAP penalties are shown by means of a series of simulated examples. Next, we introduce the Sparse Pseudo-Likelihood Inverse Covariance Estimator (SPLICE): a ℓ1-penalized pseudo-likelihood estimate of precision matrices. SPLICE estimates can be efficiently computed at the higher range of values of the regularization parameter where our heuristic analysis suggests that the pseudo-likelihood approximation works best. Simulation studies suggest that, with scarce data, many selection criteria chose higher regularization levels where the performance of the exact and pseudo-likelihood estimates is comparable. Finally, we extend previous results in the literature so they can be used to characterize asymptotic distribution of many alternative combination of loss and penalty functions for parametric (low-dimensional) models. The approximations used to derive such asymptotic results also leads to a simple criterion determining sufficient conditions for the existence of a regularization level at which the signs of the penalized parameter estimate agree with the signs of the \"true parameter\".",

"abstract": "Clouds play a major role in controlling Earth's climate, and studying global cloud distribution is the first step to advance our understanding and improve our prediction of global climate changes (such as global warming). However, cloud detection is particularly challenging in polar regions because of the snow and ice coverage. Collaborating with Dr. Eugene Clothiaux and Dr. Amy Braverman, we propose new algorithms to detection polar clouds using data collected by the Multi-angle Imaging SpectroRadiometer (MISR) and Moderate Resolution Imaging Spectroradiometer (MODIS). We devise an Enhanced Linear Correlation Matching Classification (ELCMC) algorithm to improve the MISR polar cloud detection based on the multi-angle information and the ELCMC algorithm provides a 92% average accuracy rate. The accuracy is further improved when the ELCMC results are used as labels to train nonlinear classifiers such as Quadratic Discriminate Analysis (QDA) or Gaussian kernel Support Vector Machines (SVM). Combining MISR data with the hyper-spectral information provided by MODIS, we propose an algorithm to improve the polar cloud detection. The highly accurate (97%) consensus pixels are used to train QDA on all MISR and MODIS features. Then the resulting classifier provides a 94% accuracy rate, higher than both the MISR rate (88%) and the MODIS rate (90%) over \"partly cloudy\" scenes. Because SVMs provide better classification results but require much more computation than QDA in the cloud detection problem, we use binning to reduce the computation of Gaussian kernel regularization methods. In regression we show that binning keeps the same minimax rates of the unbinned estimator and reduces the computation from O(n 3) to O(m3), with n as the sample size and m as the number of bins. To achieve the minimax rate in the k-th order Sobolev space, m needs to be in the order of O(kn 1/(2k+1)), which makes the computation of order O(n) for k = 1 and even less for larger k. On a particular polar scene, the SVM trained on 966 bins has a comparable test classification rate as the SVM trained on 27,179 samples, but significantly reduces the training time from 5.99 hours to 2.56 minutes.",

"title": "Disentangled Attribution Curves for Interpreting Random Forests and Boosted Trees.",
"abstract": " Tree ensembles, such as random forests and AdaBoost, are ubiquitous machine learning models known for achieving strong predictive performance across a wide variety of domains. However, this strong performance comes at the cost of interpretability (i.e. users are unable to understand the relationships a trained random forest has learned and why it is making its predictions). In particular, it is challenging to understand how the contribution of a particular feature, or group of features, varies as their value changes. To address this, we introduce Disentangled Attribution Curves (DAC), a method to provide interpretations of tree ensemble methods in the form of (multivariate) feature importance curves. For a given variable, or group of variables, DAC plots the importance of a variable(s) as their value changes. We validate DAC on real data by showing that the curves can be used to increase the accuracy of logistic regression while maintaining interpretability, by including DAC as an additional feature. In simulation studies, DAC is shown to out-perform competing methods in the recovery of conditional expectations. Finally, through a case-study on the bike-sharing dataset, we demonstrate the use of DAC to uncover novel insights into a dataset. ",

"abstract": "Sparse additive models are families of d-variate functions with the additive decomposition f* = Σj∈S fj*, where S is an unknown subset of cardinality s . In this paper, we consider the case where each univariate component function fj* lies in a reproducing kernel Hilbert space (RKHS), and analyze a method for estimating the unknown function f* based on kernels combined with l1-type convex regularization. Working within a high-dimensional framework that allows both the dimension d and sparsity s to increase with n, we derive convergence rates in the L2(P) and L2(Pn) norms over the class Fd,s,H of sparse additive models with each univariate function fj* in the unit ball of a univariate RKHS with bounded kernel function. We complement our upper bounds by deriving minimax lower bounds on the L2(P) error, thereby showing the optimality of our method. Thus, we obtain optimal minimax rates for many interesting classes of sparse additive models, including polynomials, splines, and Sobolev classes. We also show that if, in contrast to our univariate conditions, the d-variate function class is assumed to be globally bounded, then much faster estimation rates are possible for any sparsity s = Ω(√n), showing that global boundedness is a significant restriction in the high-dimensional setting.",

"abstract": "Deep neural network models have recently been shown to be effective in predicting single neuron responses in primate visual cortex areas V4. Despite their high predictive accuracy, these models are generally difficult to interpret. This limits their applicability in characterizing V4 neuron function. Here, we propose the DeepTune framework as a way to elicit interpretations of deep neural network-based models of single neurons in area V4. V4 is a midtier visual cortical area in the ventral visual pathway. Its functional role is not yet well understood. Using a dataset of recordings of 71 V4 neurons stimulated with thousands of static natural images, we build an ensemble of 18 neural network-based models per neuron that accurately predict its response given a stimulus image. To interpret and visualize these models, we use a stability criterion to form optimal stimuli (DeepTune images) by pooling the 18 models together. These DeepTune images not only confirm previous findings on the presence of diverse shape and texture tuning in area V4, but also provide rich, concrete and naturalistic characterization of receptive fields of individual V4 neurons. The population analysis of DeepTune images for 71 neurons reveals how different types of curvature tuning are distributed in V4. In addition, it also suggests strong suppressive tuning for nearly half of the V4 neurons. Though we focus exclusively on the area V4, the DeepTune framework could be applied more generally to enhance the understanding of other visual cortex areas.",

"abstract": "Various random fingerprinting methods are sometimes used to detect overlap between pairs of clones as a first step toward producing a minimal tiling path of clones for subsequent mapping and sequencing efforts. This paper evaluates and compares various statistical procedures for detecting pairwise overlap between clones when the fingerprints arise from any random process meeting simple, plausible assumptions about the relationship between overlap and the resulting fingerprint. Examples of such random processes include, but are not limited to, large-scale hybridization procedures designed to prepare tiling paths of clones for subsequent large-scale genomic sequencing. Our goals are to assess how well random fingerprinting can possibly detect overlap, to assess the effects of inevitable fingerprinting errors on statistical detection, to determine how one can make the best use of the data random fingerprinting provides, and to evaluate how well simple, heuristic techniques for overlap detection compare to more complex, likelihood-based approaches. The paper provides a quantitative assessment of the ability of any random fingerprinting procedure to detect various proportions of clonal overlap and shows the extent to which a small amount of experimental error will vitiate the performance of such techniques. The paper outlines a simple approximation method for constructing Bayesian overlap detectors, while concluding that detectors constructed from linear combinations of fingerprint data can be designed that will perform nearly as well as more complex, likelihood-based approaches.",

"abstract": "Clustering of data sets is a standard problem in many areas of science and engineering. The method of spectral clustering is based on embedding the data set using a kernel function, and using the top eigenvectors of the normalized Laplacian to recover the connected components. We study the performance of spectral clustering in recovering the latent labels of i.i.d. samples from a finite mixture of nonparametric distributions. The difficulty of this label recovery problem depends on the overlap between mixture components and how easily a mixture component is divided into two nonoverlapping components. When the overlap is small compared to the indivisibility of the mixture components, the principal eigenspace of the population-level normalized Laplacian operator is approximately spanned by the square-root kernelized component densities. In the finite sample setting, and under the same assumption, embedded samples from different components are approximately orthogonal with high probability when the sample size is large. As a corollary we control the fraction of samples mislabeled by spectral clustering under finite mixtures with nonparametric components.",

"abstract": "Consider the high-dimensional linear regression model $y = X \\beta^* + w$, where $y \\in {\\BBR}^n$ is an observation vector, $X \\in {\\BBR}^{n \\times d}$ is a design matrix with $d n$, ${\\beta^*} \\in {\\BBR}^d$ is an unknown regression vector, and $w \\sim {\\cal N}(0, \\sigma^2 I)$ is additive Gaussian noise. This paper studies the minimax rates of convergence for estimating ${\\beta^*}$ in either $\\ell_2$-loss and $\\ell_2$-prediction loss, assuming that $\\beta^*$ belongs to an $\\ell_q$ -ball ${\\BBB}_q(R_q)$ for some $q \\in [0,1]$. It is shown that under suitable regularity conditions on the design matrix $X$, the minimax optimal rate in $\\ell_2$ -loss and $\\ell_2$-prediction loss scales as $\\Theta\\left(R_q \\left({\\log d \\over n}\\right)^{1-{q \\over 2}}\\right)$. The analysis in this paper reveals that conditions on the design matrix $X$ enter into the rates for $\\ell_2$-error and $\\ell_2$ -prediction error in complementary ways in the upper and lower bounds. Our proofs of the lower bounds are information theoretic in nature, based on Fano's inequality and results on the metric entropy of the balls ${\\BBB}_q(R_q)$, whereas our proofs of the upper bounds are constructive, involving direct analysis of least squares over $\\ell_q$ -balls. For the special case $q=0$, corresponding to models with an exact sparsity constraint, our results show that although computationally efficient $\\ell_1$-based methods can achieve the minimax rates up to constant factors, they require slightly stronger assumptions on the design matrix $X$ than optimal algorithms involving least-squares over the $\\ell_0$-ball.",

"title": "Refining interaction search through signed iterative Random Forests.",
"abstract": "Advances in supervised learning have enabled accurate prediction in biological systems governed by complex interactions among biomolecules. However, state-of-the-art predictive algorithms are typically black-boxes, learning statistical interactions that are difficult to translate into testable hypotheses. The iterative Random Forest (iRF) algorithm took a step towards bridging this gap by providing a computationally tractable procedure to identify the stable, high-order feature interactions that drive the predictive accuracy of Random Forests (RF). Here we refine the interactions identified by iRF to explicitly map responses as a function of interacting features. Our method, signed iRF (s-iRF), describes of rules that frequently occur on RF decision paths. We refer to these rule subsets as signed interactions. Signed interactions share not only the same set of interacting features but also exhibit similar thresholding behavior, and thus describe a consistent functional relationship between interacting features and responses. We describe stable and predictive importance metrics (SPIMs) to rank signed interactions in terms of their stability, predictive accuracy, and strength of interaction. For each SPIM, we define null importance metrics that characterize its expected behavior under known structure. We evaluate our proposed approach in biologically inspired simulations and two case studies: predicting enhancer activity and spatial gene expression patterns. In the case of enhancer activity, s-iRF recovers one of the few experimentally validated high-order interactions and suggests novel enhancer elements where this interaction may be active. In the case of spatial gene expression patterns, s-iRF recovers all 11 reported links in the gap gene network. By refining the process of interaction recovery, our approach has the potential to guide mechanistic inquiry into systems whose scale and complexity is beyond human comprehension.",

"abstract": "In this paper, a novel approach is proposed for estimating traffic matrices. Our method, called PamTram for PArtial Measurement of TRAffic Matrices, couples lightweight origin-destination (OD) flow measurements along with a computationally lightweight algorithm for producing OD estimates. The first key aspect of our method is to actively select a small number of informative OD flows to measure in each estimation interval. To avoid the heavy computation of optimal selection, we use intuition from game theory to develop randomized selection rules, with the goals of reducing errors and adapting to traffic changes. We show that it is sufficient to measure only one flow per measurement period to drastically reduce errors-thus rendering our method lightweight in terms of measurement overhead. The second key aspect is an explanation and proof that an Iterative Proportional Fitting algorithm approximates traffic matrix estimates when the goal is a minimum mean-squared error; this makes our method lightweight in terms of computation overhead. A one-step error bound is provided for PamTram that bounds the average error for the worst scenario. We validate our method using data from Sprint's European Tier-1 IP backbone network and demonstrate its consistent improvement over previous methods.",

This thesis makes contribution to the study of regularization in three major aspects. First, we introduce a family of penalty functions named Composite Absolute Penalties (CAP) that are highly customizable and through which one can incorporate structural information within the data into regularization in order to improve prediction and interpretation. Efficient computation algorithms are also provided for both computing the regularization path and selecting the amount of regularization. Secondly, we introduce a Booted Lasso (BLasso) algorithm that provides a conceptual link between the popular statistical method Lasso (Tibshirani, 1996) and the machine learning method Boosting (Freund, 1995). It also serves as a simple plug-in algorithm for tracing the regularization path of general convex loss functions with general convex penalties. Finally, we study the model selection consistency of the Lasso and gives an Irrepresentible Condition which is almost necessary and sufficient for Lasso to consistently select the correct model for both small p case and large p case. The proposed methods and works are supported with theories, simulations and experiments on real datasets.",

"abstract": "Machine-learning models have demonstrated great success in learning complex patterns that enable them to make predictions about unobserved data. In addition to using models for prediction, the ability to interpret what a model has learned is receiving an increasing amount of attention. However, this increased focus has led to considerable confusion about the notion of interpretability. In particular, it is unclear how the wide array of proposed interpretation methods are related, and what common concepts can be used to evaluate them. aim to address these concerns by defining interpretability in the context of machine learning and introducing the Predictive, Descriptive, Relevant (PDR) framework for discussing interpretations. The PDR framework provides three overarching desiderata for evaluation: predictive accuracy, descriptive accuracy and relevancy, with relevancy judged relative to a human audience. Moreover, to help manage the deluge of interpretation methods, we introduce a categorization of existing techniques into model-based and post-hoc categories, with sub-groups including sparsity, modularity and simulatability. To demonstrate how practitioners can use the PDR framework to evaluate and understand interpretations, we provide numerous real-world examples. These examples highlight the often under-appreciated role played by human audiences in discussions of interpretability. Finally, based on our framework, we discuss limitations of existing methods and directions for future work. We hope that this work will provide a common vocabulary that will make it easier for both practitioners and researchers to discuss and choose from the full range of interpretation methods.",

"title": "Sparse models for sparse data: methods, limitations, visualizations and ensembles",
"abstract": "Significant recent advances in many areas of data collection and processing have introduced many challenges for modeling such data. Data sets have exploded in the number of observations and dimensionality. The explosion in dimensionality has led to advances in the modeling of high dimensional data with regularized and sparse models. One of the more interesting and challenging varieties of high dimensional data are sparse data sets. Sparse data sets arise from many important areas involving human-computer interaction, such as text and language processing, and human-human interaction, such as social networks. Our motivation in this thesis is to explore the use of sparse models for applications involving sparse data. In some cases, we have made improvements over previous methods that fundamentally involved dense models fitted on, and applied to, sparse data. In other cases, we have adapted sparse models developed for dense data sets. Along the way, we have encountered a recurring issue: due to both subsampling and regularization, we are faced with a problem that sparse models may not adequately capture the full dimensionality of such data and may be inadequate for prediction on test data. The utility of sparse models have been demonstrated in contexts with very high dimensional dense data. In this dissertation, we shall examine two applications and modeling methods involving sparse linear models and sparse matrix decompositions. Our first application involves natural language processing and ranking, the second involves recommendation systems and matrix factorization. In Chapter 2, we developed a novel and powerful visualization system. We named our system Bonsai as it enables a curated process of developing trees that partition the joint space of data and models. By exploring the product space of the space of training data, the space of modeling parameters, and the space of test data, we can explore how our models are developed based on the constraints imposed and the data they attempt to model or predict. More generally, we believe we have introduced a very fruitful means of exploring a multiplicity of models and a multiplicity of data samples. Chapter 3 is based on our work in the Netflix Prize competition. In contrast to others' use of dense models for this sparse data, we sought to introduce modeling methods with tunable sparsity. In this work, we found striking difficulties in modeling the data with sparse models, and identified concerns about the utility of sparse models for sparse data. In conclusion, this thesis presents several methods, and limitations of such methods, for modeling sparse data with sparse models. These limitations are suggestive of new directions to pursue. In particular, we are optimistic that future research in modeling methods may find new ways to tune models for density, when applied to sparse data, just as much research on models for dense data has involved tuning models for sparsity.",

"title": "Discovering word associations in news media via feature selection and sparse classification",
"abstract": "We analyze the \"image\" of a given query word in a given corpus of text news by producing a short list of other words with which this query is strongly associated. We use a number of feature selection schemes for text classification to help in this task. We apply these classification techniques using indicators of the query word's appearance in each document used as the document \"labels\" and the indicators for all other words as document predictors/features. The features selected by any scheme is then considered the list of words comprising the query word's \"image\".\n\nTo be easily understandable, a list should be extremely short with respect to the dictionary of terms present in the corpus. The approach thus requires aggressive feature (word) selection in order to single out at most a few tens of terms in a universe of hundreds of thousands or more. In addition, a word imaging scheme should scale well with the size of data (number and size of documents, size of dictionary).\n\nWe produce one scheme for feature selection through a sparse classification model. A standard classification algorithm assigns one weight per term in the predictor dictionary, in order to maximize the capacity to successfully predict the labels of document units. By imposing a sparsity constraint on the weight vector, we single out the few words that are most able to predict the presence or absence of a query word in any document. This paper compares this and several other schemes that are potentially well suited to the task of word imaging, each method presenting a different manner of feature selection.\n\nWe present two evaluations of these schemes. One evaluates the predictive classification performance of a logistic regression model trained over the corpus using only a scheme's selected features. The other is based on the judgement of human readers: a pair of word lists generated by different schemes operating on identical queries are presented to a human subject alongside a trio of document units (paragraphs) containing the query word. This subject then chooses the list which in his/her estimation is the best summary of the document units.\n\nWe apply these schemes to study the images of frequently covered countries and regions in recent news articles from the International section of the New York Times. Our preliminary experiments indicate that, while most methods perform similarly well on our data in terms of predictive performance, human-based evaluations appear to favor features selected by training of sparse logistic regression, a penalized variant of logistic regression that encourages sparse classifiers. This indicates that classification metrics based on pure predictive performance, while useful as a indicator for pre-selecting algorithms, are not enough to predict human assessment of word association algorithms.\n\n",

"title": "Spectral clustering and the high-dimensional stochastic blockmodel",
"abstract": "Networks or graphs can easily represent a diverse set of data sources that are characterized by interacting units or actors. Social networks, representing people who communicate with each other, are one example. Communities or clusters of highly connected actors form an essential feature in the structure of several empirical networks. Spectral clustering is a popular and computationally feasible method to discover these communities. The stochastic blockmodel [Social Networks 5 (1983) 109-137] is a social network model with well-defined communities; each node is a member of one community. For a network generated from the Stochastic Blockmodel, we bound the number of nodes \"misclustered\" by spectral clustering. The asymptotic results in this paper are the first clustering results that allow the number of clusters in the model to grow with the number of nodes, hence the name high-dimensional. In order to study spectral clustering under the stochastic blockmodel, we first show that under the more general latent space model, the eigenvectors of the normalized graph Laplacian asymptotically converge to the eigenvectors of a \"population\" normalized graph Laplacian. Aside from the implication for spectral clustering, this provides insight into a graph visualization technique. Our method of studying the eigenvectors of random matrices is original.",

"abstract": "Consider the standard linear regression model y = Xβ* + w, where y ∈ Rn is an observation vector, X ∈ Rn×d is a measurement matrix, β* ∈ Rd is the unknown regression vector, and w ∼ N(0, σ2I) is additive Gaussian noise. This paper determines sharp minimax rates of convergence for estimation of β* in l2 norm, assuming that β* belongs to a weak lq-ball Bq(Rq) for some q ∈ [0, 1]. We show that under suitable regularity conditions on the design matrix X, the minimax error in squared l2-norm scales as Rq (log d/n)1-q/2. In addition, we provide lower bounds on rates of convergence for general lp norm (for all p ∈ [1, + ∞], p ≠ q). Our proofs of the lower bounds are information-theoretic in nature, based on Fano's inequality and results on the metric entropy of the balls Bq(Rq). Matching upper bounds are derived by direct analysis of the solution to an optimization algorithm over Bq(Rq). We prove that the conditions on X required by optimal algorithms are satisfied with high probability by broad classes of noni.i.d. Gaussian random matrices, for which RIP or other sparse eigenvalue conditions are violated. For q = 0, l1- based methods (Lasso and Dantzig selector) achieve the minimax optimal rates in l2 error, but require stronger regularity conditions on the design than the nonconvex optimization algorithm used to determine the minimax upper bounds.",

"abstract": "We consider the problem of sampling from a strongly log-concave density in (mathbb{R}^d), and prove a non- asymptotic upper bound on the mixing time of the Metropolis-adjusted Langevin algorithm (MALA). The method draws samples by running a Markov chain obtained from the discretization of an appropriate Langevin diffusion, combined with an accept-reject step to ensure the correct stationary distribution. Relative to known guarantees for the unadjusted Langevin algorithm (ULA), our bounds reveal that the use of an accept-reject step in MALA leads to an exponentially improved dependence on the error-tolerance. Concretely, in order to obtain samples with TV error at most δ for a density with condition number κ, we show that MALA requires (O(kappa d log(1/delta))) steps, as compared to the (O(kappa^2d/delta^2)) steps established in past work on ULA. We also demonstrate the gains of MALA over ULA for weakly log-concave densities. Furthermore, we derive mixing time bounds for a zeroth-order method Metropolized random walk (MRW) and show that it mixes (O(kappa d)) slower than MALA. We provide numerical examples that support our theoretical findings, and demonstrate the potential gains of Metropolis-Hastings adjustment for Langevin-type algorithms.",

"title": "Counting and exploring sizes of Markov equivalence classes of directed acyclic graphs.",
"abstract": "When learning a directed acyclic graph (DAG) model via observational data, one generally cannot identify the underlying DAG, but can potentially obtain a Markov equivalence class. The size (the number of DAGs) of a Markov equivalence class is crucial to infer causal effects or to learn the exact causal DAG via further interventions. Given a set of Markov equivalence classes, the distribution of their sizes is a key consideration in developing learning methods. However, counting the size of an equivalence class with many vertices is usually computationally infeasible, and the existing literature reports the size distributions only for equivalence classes with ten or fewer vertices.In this paper, we develop a method to compute the size of a Markov equivalence class. We first show that there are five types of Markov equivalence classes whose sizes can be formulated as five functions of the number of vertices respectively. Then we introduce a new concept of a rooted sub-class. The graph representations of rooted subclasses of a Markov equivalence class are used to partition this class recursively until the sizes of all rooted subclasses can be computed via the five functions. The proposed size counting is efficient for Markov equivalence classes of sparse DAGs with hundreds of vertices. Finally, we explore the size and edge distributions of Markov equivalence classes and find experimentally that, in general, (1) most Markov equivalence classes are half completed and their average sizes are small, and (2) the sizes of sparse classes grow approximately exponentially with the numbers of vertices.",

"title": "On Model Selection Consistency of Lasso",
"abstract": "Sparsity or parsimony of statistical models is crucial for their proper interpretations, as in sciences and social sciences. Model selection is a commonly used method to find such models, but usually involves a computationally heavy combinatorial search. Lasso (Tibshirani, 1996) is now being used as a computationally feasible alternative to model selection. Therefore it is important to study Lasso for model selection purposes. In this paper, we prove that a single condition, which we call the Irrepresentable Condition, is almost necessary and sufficient for Lasso to select the true model both in the classical fixed p setting and in the large p setting as the sample size n gets large. Based on these results, sufficient conditions that are verifiable in practice are given to relate to previous works and help applications of Lasso for feature selection and sparse representation. This Irrepresentable Condition, which depends mainly on the covariance of the predictor variables, states that Lasso selects the true model consistently if and (almost) only if the predictors that are not in the true model are \"irrepresentable\" (in a sense to be clarified) by predictors that are in the true model. Furthermore, simulations are carried out to provide insights and understanding of this result.",

"abstract": "We study the model selection property of the Elastic Net. In the classical settings when p (the number of predictors) and q (the number of predictors with non-zero coefficients in the true linear model) are fixed, Yuan and Lin (2007) give a necessary and sufficient condition for the Elastic Net to consistently select the true model. They showed that it consistently selects the true model if and only if there exist suitable sequences λ1 (n) and λ2 (n) that satisfy EIC (which is defined later in the paper). Here we study the general case when p, q, and n all go to infinity. For general scalings of p, q, and n, when gaussian noise is assumed, sufficient conditions are given such that EIC guarantees the Elastic Net's model selection consistency. We show that to make these conditions hold, n should grow at a rate faster than qlog(p - q). We compare the variable selection performance of the Elastic Net with that of the Lasso. Through theoretical results find simulation studies, we provide insights into when the Elastic Net can consistently select the true model even when the Lasso cannot. We also point out through examples that when the Lasso cannot select the true model, it is very likely that the Elastic Net cannot select the true model either.",

SparseL2Boost yields sparser solutions than the previously proposed L2Boosting by minimizing some penalized L2-loss functions, the FPE model selection criteria, through small-step gradient descent. Although boosting may give already relatively sparse solutions, for example corresponding to the soft-thresholding estimator in orthogonal linear models, there is sometimes a desire for more sparseness to increase prediction accuracy and ability for better variable selection: such goals can be achieved with SparseL2Boost. We prove an equivalence of SparseL2Boost to Breiman's nonnegative garrote estimator for orthogonal linear models and demonstrate the generic nature of SparseL2Boost for nonparametric interaction modeling. For an automatic selection of the tuning parameter in SparseL2Boost we propose to employ the gMDL model selection criterion which can also be used for early stopping of L2Boosting. Consequently, we can select between SparseL2Boost and L2Boosting by comparing their gMDL scores.",

"abstract": "Convolutional neural networks (CNNs) achieve state-of-the-art performance in a wide variety of tasks in computer vision. However, interpreting CNNs still remains a challenge. This is mainly due to the large number of parameters in these networks. Here, we investigate the role of compression and particularly pruning filters in the interpretation of CNNs. We exploit our recently-proposed greedy structural compression scheme that prunes filters in a trained CNN. In our compression, the filter importance index is defined as the classification accuracy reduction (CAR) of the network after pruning that filter. The filters are then iteratively pruned based on the CAR index. We demonstrate the interpretability of CAR-compressed CNNs by showing that our algorithm prunes filters with visually redundant pattern selectivity. Specifically, we show the importance of shape-selective filters for object recognition, as opposed to color-selective filters. Out of top 20 CAR-pruned filters in AlexNet, 17 of them in the first layer and 14 of them in the second layer are color-selective filters. Finally, we introduce a variant of our CAR importance index that quantifies the importance of each image class to each CNN filter.

"title": "The Lasso under Heteroscedasticity",
"abstract": "The performance of the Lasso is well understood under the assumptions of the\nstandard linear model with homoscedastic noise. However, in several\napplications, the standard model does not describe the important features of\nthe data. This paper examines how the Lasso performs on a non-standard model\nthat is motivated by medical imaging applications. In these applications, the\nvariance of the noise scales linearly with the expectation of the observation.\nLike all heteroscedastic models, the noise terms in this Poisson-like model are\n\\textit{not} independent of the design matrix.\n More specifically, this paper studies the sign consistency of the Lasso under\na sparse Poisson-like model. In addition to studying sufficient conditions for\nthe sign consistency of the Lasso estimate, this paper also gives necessary\nconditions for sign consistency. Both sets of conditions are comparable to\nresults for the homoscedastic model, showing that when a measure of the signal\nto noise ratio is large, the Lasso performs well on both Poisson-like data and\nhomoscedastic data.\n Simulations reveal that the Lasso performs equally well in terms of model\nselection performance on both Poisson-like data and homoscedastic data (with\nproperly scaled noise variance), across a range of parameterizations. Taken as\na whole, these results suggest that the Lasso is robust to the Poisson-like\nheteroscedastic noise.",

"title": "Structural Compression of Convolutional Neural Networks Based on Greedy Filter Pruning.",
"abstract": "Convolutional neural networks (CNNs) have state-of-the-art performance on many problems in machine vision. However, networks with superior performance often have millions of weights so that it is difficult or impossible to use CNNs on computationally limited devices or to humanly interpret them. A myriad of CNN compression approaches have been proposed and they involve pruning and compressing the weights and filters. In this article, we introduce a greedy structural compression scheme that prunes filters in a trained CNN. We define a filter importance index equal to the classification accuracy reduction (CAR) of the network after pruning that filter (similarly defined as RAR for regression). We then iteratively prune filters based on the CAR index. This algorithm achieves substantially higher classification accuracy in AlexNet compared to other structural compression schemes that prune filters. Pruning half of the filters in the first or second layer of AlexNet, our CAR algorithm achieves 26% and 20% higher classification accuracies respectively, compared to the best benchmark filter pruning scheme. Our CAR algorithm, combined with further weight pruning and compressing, reduces the size of first or second convolutional layer in AlexNet by a factor of 42, while achieving close to original classification accuracy through retraining (or fine-tuning) network. Finally, we demonstrate the interpretability of CAR-compressed CNNs by showing that our algorithm prunes filters with visually redundant functionalities. In fact, out of top 20 CAR-pruned filters in AlexNet, 17 of them in the first layer and 14 of them in the second layer are color-selective filters as opposed to shape-selective filters. To our knowledge, this is the first reported result on the connection between compression and interpretability of CNNs.",

"title": "Ten Simple Rules for Effective Statistical Practice.",
"abstract": "Several months ago, Phil Bourne, the initiator and frequent author of the wildly successful and incredibly useful “Ten Simple Rules” series, suggested that some statisticians put together a Ten Simple Rules article related to statistics. (One of the rules for writing a PLOS Ten Simple Rules article is to be Phil Bourne [1]. In lieu of that, we hope effusive praise for Phil will suffice.)Implicit in the guidelines for writing Ten Simple Rules [1] is “know your audience.” We developed our list of rules with researchers in mind: researchers having some knowledge of statistics, possibly with one or more statisticians available in their building, or possibly with a healthy do-it-yourself attitude and a handful of statistical packages on their laptops. We drew on our experience in both collaborative research and teaching, and, it must be said, from our frustration at being asked, more than once, to “take a quick look at my student’s thesis/my grant application/my referee’s report: it needs some input on the stats, but it should be pretty straightforward.”There are some outstanding resources available that explain many of these concepts clearly and in much more detail than we have been able to do here: among our favorites are Cox and Donnelly [2], Leek [3], Peng [4], Kass et al. [5], Tukey [6], and Yu [7].Every article on statistics requires at least one caveat. Here is ours: we refer in this article to “science” as a convenient shorthand for investigations using data to study questions of interest. This includes social science, engineering, digital humanities, finance, and so on. Statisticians are not shy about reminding administrators that statistical science has an impact on nearly every part of almost all organizations.",

"title": "MISR Cloud Detection over Ice and Snow Based on Linear Correlation Matching",
"abstract": "Cloud detection is a crucial step in any climate modelling or prediction. Multi-angle Imaging SpectroRadiometer (MISR) was launched in 1999 by NASA to provide 9 angle and 4 band data to retrieve or estimate the cloud height and hence cloud detection. However, cloud detection even with MISR data has been proven very di-cult over ice and snow. In this paper, we bypass the cloud height estimation step to directly tackle cloud detection by using features of ice and snow (no cloud) pixels from difierent MISR angles. We propose the linear correlation matching classiflcation (LCMC) algorithm based on Fisher linear correlation tests. We compare LCMC with the Steroscopically-Derived Cloud Mask (SDCM), which is the cloud mask from MISR Level 2 Top-of-the atmosphere Cloud algorithm (known as L2TC), and flnd that LCMC gives more coverage and more robust results judged by visual inspection of flner resolution images. LCMC can also detect the very thin clouds most of the time. Moreover, LCMC is computationally much faster than L2TC and easier to implement. We hope to combine LCMC with L2TC in the future to improve the accuracy of the L2TC cloud height retrieval.",

"abstract": "Summary In this paper, the relationship between code length and the selection of the number of bins for a histogram density is considered for a sequence of iid observations on [0,1]. First, we use a shortest code length criterion to select the number of bins for a histogram. A uniform almost sure asymptotic expansion for the code length is given and it is used to prove the asymptotic optimality of the selection rule. In addition, the selection rule is consistent if the true density is uniform [0,1]. Secondly, we deal with the problem: what is the “best” achievable average code length with underlying density functionf? Minimax lower bounds are derived for the average code length over certain smooth classes of underlying densitiesf. For the smooth class with bounded first derivatives, the rate in the lower bound is shown to be achieved by a code based on a sequence of histograms whose number of bins is changed predictively. Moreover, this best code can be modified to ensure that the almost sure version of the code length has asymptotically the same behavior as its expected value, i.e., the average code length.",

"abstract": "We study a class of weakly identifiable location-scale mixture models for which the maximum likelihood estimates based on $n$ i.i.d. samples are known to have lower accuracy than the classical $n^{- frac{1}{2}}$ error. We investigate whether the Expectation-Maximization (EM) algorithm also converges slowly for these models. We first demonstrate via simulation studies a broad range of over-specified mixture models for which the EM algorithm converges very slowly, both in one and higher dimensions. We provide a complete analytical characterization of this behavior for fitting data generated from a multivariate standard normal distribution using two-component Gaussian mixture with varying location and scale parameters. Our results reveal distinct regimes in the convergence behavior of EM as a function of the dimension $d$. In the multivariate setting ($d geq 2$), when the covariance matrix is constrained to a multiple of the identity matrix, the EM algorithm converges in order $(n/d)^{frac{1}{2}}$ steps and returns estimates that are at a Euclidean distance of order ${(n/d)^{-frac{1}{4}}}$ and ${ (n d)^{- frac{1}{2}}}$ from the true location and scale parameter respectively. On the other hand, in the univariate setting ($d = 1$), the EM algorithm converges in order $n^{frac{3}{4} }$ steps and returns estimates that are at a Euclidean distance of order ${ n^{- frac{1}{8}}}$ and ${ n^{-frac{1} {4}}}$ from the true location and scale parameter respectively. Establishing the slow rates in the univariate setting requires a novel localization argument with two stages, with each stage involving an epoch-based argument applied to a different surrogate EM operator at the population level. We also show multivariate ($d geq 2$) examples, involving more general covariance matrices, that exhibit the same slow rates as the univariate case.",

"abstract": "All fields of science are now inundated with massive amounts of data, which have the potential to answer fundamental questions. Genomics is one particular example, exploring questions like: How does the human genome work? What genome variants make us more prone to diseases? To find answers to these questions, it is crucial to develop statistical and machine learning methods that can scale up, particularly through efficient data storage and communication. Equally crucial, but less emphasized, is the possession of data wisdom—a rebranding of the best elements of applied statistics in a recent note at ODBMS.org (http://www.odbms.org/2015/04/data-wisdom-for-data-science/). The note at ODBMS.org contains ten sets of questions a practitioner can ask to cultivate data wisdom. Although there has been much recent excitement about big data, having enough data relevant to the problem is the key to gaining meaningful answers in genomics. Data wisdom gives us the insight into how these data would look, how much information a dataset really contains, and how to extract it. In this paper, we expand on the ten sets of questions and illustrate where and how data wisdom can be integrated into computational genomics research.",

"title": "Reversible MCMC on Markov equivalence classes of sparse directed acyclic graphs",
"abstract": "Graphical models are popular statistical tools which are used to represent dependent or causal complex systems. Statistically equivalent causal or directed graphical models are said to belong to a Markov equivalent class. It is of great interest to describe and understand the space of such classes. However, with currently known algorithms, sampling over such classes is only feasible for graphs with fewer than approximately 20 vertices. In this paper, we design reversible irreducible Markov chains on the space of Markov equivalent classes by proposing a perfect set of operators that determine the transitions of the Markov chain. The stationary distribution of a proposed Markov chain has a closed form and can be computed easily. Specifically, we construct a concrete perfect set of operators on sparse Markov equivalence classes by introducing appropriate conditions on each possible operator. Algorithms and their accelerated versions are provided to efficiently generate Markov chains and to explore properties of Markov equivalence classes of sparse directed acyclic graphs (DAGs) with thousands of vertices. We find experimentally that in most Markov equivalence classes of sparse DAGs, (1) most edges are directed, (2) most undirected subgraphs are small and (3) the number of these undirected subgraphs grows approximately linearly with the number of vertices.",

"title": "Fusing information from MISR and MODIS for polar cloud detection",
"abstract": "Clouds play a major role in controlling Earth's climate, and cloud detection is a crucial step in the numerical weather prediction, and global climate models. Multi-angle imaging spectroradiometer (MLSR) and moderate resolution imaging spectroradiometer (MODIS) were launched in 1999 by clouds. However, cloud detection algorithms using either MISR or MODIS data separately do not take full advantage of the data collected by both sensors. In this paper, we propose and test two schemes to combine MISR and MODIS data for cloud detection in polar regions, Both schemes are follow-ups of a two-step polar cloud detection algorithm using MISR data: enhanced linear correlation matching classification followed by quadratic discriminate analysis (ELMS-QDA) (T, Shi et al.). The first scheme is mapping the MODIS cloud detection results to the MISR grid based on a nearest neighbor method, then only reporting the agreed pixels of the ELCMC-QDA results (from MISR) and MODIS operational results. This scheme improves the classification accuracy, but reduces the coverage of the results. Instead of combining the MISR and MODIS results directly, the second scheme uses the agreed pixels of ELCMC results and MODIS operational results as the training data for the QDA on MISR features, and output the results from the QDA. Both schemes are tested over a region where expert labels show that both MISR and MODIS operational algorithms do not work well (according to expert labels, 53% and 12.72% misclassification rates for MISR and MODIS operational algorithms respectively). The first scheme only makes 0.72% of errors, but leaves 68.72% of pixels unclassified. The second scheme reaches a 2.93% of misclassification rate, which is smaller than a 4.09% rate from ELCMC-QDA, and it provides a full coverage. Hence we propose using QDA on ELCMC and MODIS agreed pixels as an algorithm to fuse the MISR and MODIS information for the polar cloud detection.",

We argue that the cusum path plot can bring out, more effectively than the sequential plot, those aspects of a Markov sampler which tell the user how quickly or slowly the sampler is moving around in its sample space, in the direction of the summary statistic. The proposal is then illustrated in four examples which represent situations where the cusum path plot works well and not well. Moreover, a rigorous analysis is given for one of the examples. We conclude that the cusum path plot is an effective tool for convergence diagnostics of a Markov sampler and for comparing different Markov samplers.",

Focusing on non-parametric regression in a reproducing kernel Hilbert space, we analyze the early stopping strategy for a form of gradient-descent applied to the least-squares loss function. We propose a data-dependent stopping rule that does not involve hold-out or cross-validation data, and we prove upper bounds on the squared error of the resulting function estimate, measured in either the L2(P) and L2(Pn) norm. These upper bounds lead to minimax-optimal rates for various kernel classes, including Sobolev smoothness classes and other forms of reproducing kernel Hilbert spaces. We show through simulation that our stopping rule compares favorably to two other stopping rules, one based on hold-out data and the other based on Stein's unbiased risk estimate. We also establish a tight connection between our early stopping strategy and the solution path of a kernel ridge regression estimator.",

"abstract": "Random Forests has become increasingly popular in Machine Learning. It is regarded as one of the best off-the-shelf classifiers. This dissertation contributes to further study and improve the Random Forest algorithm and applies it to the field of drug discovery. It consists of three loosely related topics on Random Forests. It is motivated by several problems the author came across when doing internships and research on Random Forests in the pharmaceutical industry and finance industry. The first part develops a sequential screening procedure based on Random Forests for biochemistry labs in search of drug discovery. We show its effectiveness in searching active compounds compared with a traditional two rounds procedure. We further compare our Random Forests sequential screening procedure with the sequential screening procedures based on two other most promising classification machines for QSAR modeling: Support Vector Machine and Binary Kernel discrimination, and show favorable results. The second part strives to improve the Random Forests classifier, making it able to handle Unbalanced classification, i.e., at least one of the classes constitutes only a very small minority of the data. Two methods of learning imbalanced data based on Random Forests are proposed. We compare their prediction performance with existing methods on some benchmark data sets and show favorable results. We further extend the idea of dealing with imbalanced data to Support Vector Machine. The two most accurate classification machines to date are compared in their ability to learn imbalanced data. The last part aims at making exploratory research on unsupervised learning with Random Forests. We present how the Random Forests proximity measure can be derived in the unsupervised learning setting, and further study its performance when applied to cluster analysis and multidimensional scaling.",

"title": "Binning in Gaussian Kernel Regularization",
"abstract": "Gaussian kernel regularization is widely used in the machine learning literature and proven successful in many empirical experiments. The periodic version of the Gaussian kernel reg- ularization has been shown to be minimax rate optimal in estimating functions in any flnite order Sobolev spaces. However, for a data set with n points, the computation complexity of the Gaussian kernel regularization method is of order O(n3). In this paper we propose to use binning to reduce the computation of Gaussian kernel regularization in both regression and classiflcation. For the periodic Gaussian kernel regression, we show that the binned estimator achieves the same minimax rates of the unbinned estimator, but the computation is reduced to O(m3) with m as the number of bins. To achieve the minimax rate in the k-th order Sobolev space, m needs to be in the order of O(kn1=(2k+1)), which makes the binned estimator computation of order O(n) for k = 1 and even less for larger k. Our simulations show that the binned estimator (binning 120 data points into 20 bins in our simulation) provides almost the same accuracy with only 0.4% of computation time. For classiflcation, binning with the L2-loss Gaussian kernel regularization and the Gaussian kernel Support Vector Machines is tested in a polar cloud detection problem. With basically the same computation time, the L2-loss Gaussian kernel regularization on 966 bins achieves better test classiflcation rate (79.22%) than that (71.40%) on 966 randomly sampled data. Using the OSU-SVM Matlab package, the SVM trained on 966 bins has a comparable test classiflcation rate as the SVM trained on 27,179 samples, but reduces the training time from 5.99 hours to 2.56 minutes. The SVM trained on 966 randomly selected samples has a similar training time as and a slightly worse test classiflcation rate than the SVM on 966 bins, but has 67% more",

"title": "Lasso adjustments of treatment effect estimates in randomized experiments",
"abstract": "We provide a principled way for investigators to analyze randomized experiments when the number of covariates is large. Investigators often use linear multivariate regression to analyze randomized experiments instead of simply reporting the difference of means between treatment and control groups. Their aim is to reduce the variance of the estimated treatment effect by adjusting for covariates. If there are a large number of covariates relative to the number of observations, regression may perform poorly because of overfitting. In such cases, the least absolute shrinkage and selection operator (Lasso) may be helpful. We study the resulting Lasso-based treatment effect estimator under the Neyman–Rubin model of randomized experiments. We present theoretical conditions that guarantee that the estimator is more efficient than the simple difference-of-means estimator, and we provide a conservative estimator of the asymptotic variance, which can yield tighter confidence intervals than the difference-of-means estimator. Simulation and data examples show that Lasso-based adjustment can be advantageous even when the number of covariates is less than the number of observations. Specifically, a variant using Lasso for selection and ordinary least squares (OLS) for estimation performs particularly well, and it chooses a smoothing parameter based on combined performance of Lasso and OLS.",

"title": "Distributed modal identification using restricted auto regressive models",
"abstract": "Advances in Wireless Sensor Networks (WSN) technology have provided promising possibilities in detecting a change in the state of a structure through monitoring its features estimated using sensor data. The natural vibration properties of the structure are a set of features commonly used for this purpose and are often estimated using a multivariate autoregressive model (AR model) for the measured structure's response to ambient vibrations. Fitting a multivariate AR model to the observed acceleration requires the computation of the lagged covariance between the measurements in all nodes. The resulting volume of data transmission causes significant latency due to the low data bandwidth of WSNs in addition to having a high transmission energy cost. In this paper, a set of restrictions to the estimation of the AR model is introduced. Such restrictions significantly reduce the volume of data flowing through the WSN thus reducing the latency in obtaining modal parameters and extending the battery lifetime of the WSN. A physical motivation is given for the restrictions based on a linear model for a multi-degree of freedom vibrating system. Stabilisation diagrams are compared for the restricted and full AR models fitted using data simulated from linear structures and real data collected from a WSN deployed on the Golden Gate Bridge (GGB). These stabilisation diagrams show that the estimated modes using the restricted AR models are of comparable quality to that of the full AR model while substantially reducing the volume of transmitted data.",

In this paper, we first extend the Sparse Dis- criminate Analysis (SDA) of Clemmensen et al.. We call this Multi-task Sparse Discriminate Analysis (MtSDA). MtSDA formulates multi-label prediction as a quadratic optimization problem whereas SDA obtains single labels via a nearest class mean rule. Second, we propose a class of equicorrelation matrices to use in MtSDA which includes the identity ma- trix. MtSDA with both matrices are compared with single- task learning (SVM and LDA+SVM) and multi-task learning (HSML). The comparisons are made on real data sets in terms of AUC and F-measure. The data results show that MtSDA outperforms other methods substantially almost all the time and in some cases MtSDA with the equicorrelation matrix substantially outperforms MtSDA with identity matrix .",

"title": "Concise comparative summaries (CCS) of large text corpora with a human experiment.",
"abstract": "In this paper we propose a general framework for topic-specific summarization of large text corpora and illustrate how it can be used for the analysis of news databases. Our framework, concise comparative summarization (CCS), is built on sparse classification methods. CCS is a lightweight and flexible tool that offers a compromise between simple word frequency based methods currently in wide use and more heavyweight, model-intensive methods such as latent Dirichlet allocation (LDA). We argue that sparse methods have much to offer for text analysis and hope CCS opens the door for a new branch of research in this important field. For a particular topic of interest (e.g., China or energy), CSS automatically labels documents as being either on-or off-topic (usually via keyword search), and then uses sparse classification methods to predict these labels with the high-dimensional counts of all the other words and phrases in the documents. The resulting small set of phrases found as predictive are then harvested as the summary. To validate our tool, we, using news articles from the New York Times international section, designed and conducted a human survey to compare the different summarizers with human understanding. We demonstrate our approach with two case studies, a media analysis of the framing of \"Egypt\" in the New York Times throughout the Arab Spring and an informal comparison of the New York Times' and Wall Street Journal's coverage of \"energy.\" Overall, we find that the Lasso with L-2 normalization can be effectively and usefully used to summarize large corpora, regardless of document size.",

First, we provide a non-asymptotic upper bound on the mixing time of the Metropolized HMC with explicit choices of stepsize and number of leapfrog steps. This bound gives a precise quantification of the faster convergence of Metropolized HMC relative to simpler MCMC algorithms such as the Metropolized random walk, or Metropolized Langevin algorithm. Second, we provide a general framework for sharpening mixing time bounds Markov chains initialized at a substantial distance from the target distribution over continuous spaces. We apply this sharpening device to the Metropolized random walk and Langevin algorithms, thereby obtaining improved mixing time bounds from a non-warm initial distribution. ",

"title": "Stability and Convergence Trade-off of Iterative Optimization Algorithms.",
"abstract": "The overall performance or expected excess risk of an iterative machine learning algorithm can be decomposed into training error and generalization error. While the former is controlled by its convergence analysis, the latter can be tightly handled by algorithmic stability. The machine learning community has a rich history investigating convergence and stability separately. However, the question about the trade-off between these two quantities remains open. In this paper, we show that for any iterative algorithm at any iteration, the overall performance is lower bounded by the minimax statistical error over an appropriately chosen loss function class. This implies an important trade-off between convergence and stability of the algorithm -- a faster converging algorithm has to be less stable, and vice versa. As a direct consequence of this fundamental tradeoff, new convergence lower bounds can be derived for classes of algorithms constrained with different stability bounds. In particular, when the loss function is convex (or strongly convex) and smooth, we discuss the stability upper bounds of gradient descent (GD) and stochastic gradient descent and their variants with decreasing step sizes. For Nesterovu0027s accelerated gradient descent (NAG) and heavy ball method (HB), we provide stability upper bounds for the quadratic loss function. Applying existing stability upper bounds for the gradient methods in our trade-off framework, we obtain lower bounds matching the well-established convergence upper bounds up to constants for these algorithms and conjecture similar lower bounds for NAG and HB. Finally, we numerically demonstrate the tightness of our stability bounds in terms of exponents in the rate and also illustrate via a simulated logistic regression problem that our stability bounds reflect the generalization errors better than the simple uniform convergence bounds for GD and NAG.",

"title": "Model Selection in Gaussian Graphical Models: High-Dimensional Consistency of l1-regularized MLE",
"abstract": "We consider the problem of estimating the graph structure associated with a Gaussian Markov random field (GMRF) from i.i.d. samples. We study the p erformance of study the performance of the ℓ1-regularized maximum likelihood estimator in the high-dimensional setting, where the number of nodes in the graph p, the number of edges in the graph s and the maximum node degree d, are allowed to grow as a function of the number of samples n. Our main result provides sufficient conditions on (n, p, d) for the ℓ1-regularized MLE estimator to recover all the edges of the graph with high probability. Under some conditions on the model covariance, we show that model selection can be achieved for sample sizes n = (d2 log(p)), with the error decaying as O(exp( clog(p))) for some constant c. We illustrate our theoretical results via simulations and sho w good correspondences between the theoretical predictions and behavior in simulations. The area of high-dimensional statistics deals with estimat ion in the \"large p, small n\" setting, where p and n correspond, respectively, to the dimensionality of the dat a and the sample size. Such high- dimensional problems arise in a variety of applications, among them remote sensing, computational biology and natural language processing, where the model dimension may be comparable or sub- stantially larger than the sample size. It is well-known tha t such high-dimensional scaling can lead to dramatic breakdowns in many classical procedures. In the absence of additional model assumptions, it is frequently impossible to obtain consistent procedure s when p ≫ n. Accordingly, an active line of statistical research is based on imposing various restri ctions on the model—-for instance, spar- sity, manifold structure, or graphical model structure—-and then studying the scaling behavior of different estimators as a function of sample size n, ambient dimension p and additional parameters related to these structural assumptions. In this paper, we study the problem of estimating the graph structure of a Gauss Markov random field (GMRF) in the high-dimensional setting. This graphical model selection problem can be reduced to the problem of estimating the zero-pattern of the inverse covariance or concentration matrix �∗. A line of recent work (1, 2, 3, 4) has studied estimators based on minimizing Gaussian log-likelihood penalized by the ℓ1 norm of the entries (or the off-diagonal entries) of the conc entration matrix. The resulting optimization problem is a log-determinant program, which can be solved in polynomial time with interior point methods (5), or by faster co-ordina te descent algorithms (3, 4). In recent work, Rothman et al. (1) have analyzed some aspects of high-dimensional behavior, in particular establishing consistency in Frobenius norm under certain conditions on the model covariance and under certain scalings of the sparsity, sample size, and ambient model dimension.",

"abstract": "Many algorithms for inferring causality rely heavily on the faithfulness assumption. The main justification for imposing this assumption is that the set of unfaithful distributions has Lebesgue measure zero, since it can be seen as a collection of hypersurfaces in a hypercube. However, due to sampling error the faithfulness condition alone is not sufficient for statistical estimation, and strong-faithfulness has been proposed and assumed to achieve uniform or high-dimensional consistency. In contrast to the plain faithfulness assumption, the set of distributions that is not strong-faithful has nonzero Lebesgue measure and in fact, can be surprisingly large as we show in this paper. We study the strong-faithfulness condition from a geometric and combinatorial point of view and give upper and lower bounds on the Lebesgue measure of strong-faithful distributions for various classes of directed acyclic graphs. Our results imply fundamental limitations for the PC-algorithm and potentially also for other algorithms based on partial correlation testing in the Gaussian case.",

"abstract": "We consider supervised learning problems where the features are embedded in a graph, such as gene expressions in a gene network. In this context, it is of much interest to automatically select a subgraph with few connected components; by exploiting prior knowledge, one can indeed improve the prediction performance or obtain results that are easier to interpret. Regularization or penalty functions for selecting features in graphs have recently been proposed, but they raise new algorithmic challenges. For example, they typically require solving a combinatorially hard selection problem among all connected subgraphs. In this paper, we propose computationally feasible strategies to select a sparse and well-connected subset of features sitting on a directed acyclic graph (DAG). We introduce structured sparsity penalties over paths on a DAG called \\\"path coding\\\" penalties. Unlike existing regularization functions that model long-range interactions between features in a graph, path coding penalties are tractable. The penalties and their proximal operators involve path selection problems, which we efficiently solve by leveraging network flow optimization. We experimentally show on synthetic, image, and genomic data that our approach is scalable and leads to more connected subgraphs than other regularization functions for graphs.",

"title": "Restricted Eigenvalue Properties for Correlated Gaussian Designs",
"abstract": "Methods based on l1-relaxation, such as basis pursuit and the Lasso, are very popular for sparse regression in high dimensions. The conditions for success of these methods are now well-understood: (1) exact recovery in the noiseless setting is possible if and only if the design matrix X satisfies the restricted nullspace property, and (2) the squared l2-error of a Lasso estimate decays at the minimax optimal rate k log p / n, where k is the sparsity of the p-dimensional regression problem with additive Gaussian noise, whenever the design satisfies a restricted eigenvalue condition. The key issue is thus to determine when the design matrix X satisfies these desirable properties. Thus far, there have been numerous results showing that the restricted isometry property, which implies both the restricted nullspace and eigenvalue conditions, is satisfied when all entries of X are independent and identically distributed (i.i.d.), or the rows are unitary. This paper proves directly that the restricted nullspace and eigenvalue conditions hold with high probability for quite general classes of Gaussian matrices for which the predictors may be highly dependent, and hence restricted isometry conditions can be violated with high probability. In this way, our results extend the attractive theoretical guarantees on l1-relaxations to a much broader class of problems than the case of completely independent or unitary designs.",

"abstract": "Bagging is one of the most effective computationally intensive procedures to im- prove on unstable estimators or classifiers, useful especially for high dimensional data set problems. Here we formalize the notion of instability and derive theoretical results to analyze the variance reduction effect of bagging (or its variant) in mainly hard decision problems, which include estimation after testing in regression and decision trees for continuous regression functions and classifiers. Hard decisions create insta- bility, and bagging is shown to smooth such hard decisions yielding smaller variance and mean squared error. With theoretical explanations, we motivate subagging based on subsampling as an alternative aggregation scheme. It is computationally cheaper but still showing approximately the same accuracy as bagging. Moreover, our theory reveals improvements in first order and in line with simulation studies. In particular, we obtain an asymptotic limiting distribution at the cube-root rate for the split point when fitting piecewise constant functions. Denoting sample size by n, it follows that in a cylindric neighborhood of diameter n 1/3 of the theoretically optimal split point, the variance and mean squared error reduction of subagging can be characterized analytically. Because of the slow rate, our reasoning also provides an explanation on the global scale for the whole covariate space in a decision tree with finitely many splits.",

"title": "Fast MCMC Sampling Algorithms on Polytopes.",
"abstract": "We propose and analyze two new MCMC sampling algorithms, the Vaidya walk and the John walk, for generating samples from the uniform distribution over a polytope. Both random walks are sampling algorithms derived from interior point methods. The former is based on volumetric-logarithmic barrier introduced by Vaidya whereas the latter uses Johnu0027s ellipsoids. We show that the Vaidya walk mixes in significantly fewer steps than the logarithmic-barrier based Dikin walk studied in past work. For a polytope in ℝd defined by n ≥ d linear constraints, we show that the mixing time from a warm start is bounded as O(n0.5d1.5), compared to the O(nd) mixing time bound for the Dikin walk. The cost of each step of the Vaidya walk is of the same order as the Dikin walk, and at most twice as large in terms of constant pre-factors. For the John walk, we prove an O(d2.5 log4(n/d) bound on its mixing time and conjecture that an improved variant of it could achieve a mixing time of O(d2 poly-log(n/d)). Additionally, we propose variants of the Vaidya and John walks that mix in polynomial time from a deterministic starting point. The speed-up of the Vaidya walk over the Dikin walk are illustrated in numerical examples.",

"abstract": " High-dimensional statistical inference deals with models in which the the number of parameters p is comparable to or larger than the sample size n. Since it is usually impossible to obtain consistent procedures unless $p/n\\rightarrow0$, a line of recent work has studied models with various types of low-dimensional structure, including sparse vectors, sparse and structured matrices, low-rank matrices and combinations thereof. In such settings, a general approach to estimation is to solve a regularized optimization problem, which combines a loss function measuring how well the model fits the data with some regularization function that encourages the assumed structure. This paper provides a unified framework for establishing consistency and convergence rates for such regularized M-estimators under high-dimensional scaling. We state one main theorem and show how it can be used to re-derive some existing results, and also to obtain a number of new results on consistency and convergence rates, in both $\\ell_2$-error and related norms. Our analysis also identifies two key properties of loss and regularization functions, referred to as restricted strong convexity and decomposability, that ensure corresponding regularized M-estimators have fast convergence rates and which are optimal in many well-studied cases.

"abstract": "In this paper, we study the model selection property of the Elastic net. In the classical settings when p (the number of predictors) and q (the number of predictors with non-zero coefficients in the true linear model) are fixed, Yuan and Lin (2007) give a necessary and sufficient condition for the Elastic net to consistently select the true model, which is called the Elastic Irrepresentable Condition (EIC) in this paper. Here we study the general case when p, q and n all go to infinity. For general scalings of p, q and n, when gaussian noise is assumed, sufficient conditions on p, q and n ar given in this paper such that EIC guarantees the Elastic net's model selection consistency. We show that to make these conditions hold, n should grow at a rate faster than q log(p q). For the classical case, when p and q are fixed, we also study the relationship between EIC and the Irrepresentable Condition (IC) which is necessary and sufficient for the Lasso to select the true model. Through theoretical results and simulation studies, we provide insights into when and why EIC is weaker than IC and when the Elastic net can consistently select the true model even when the Lasso can not.",

"abstract": "Deep neural networks (DNNs) have achieved impressive predictive performance due to their ability to learn complex, non-linear relationships between variables. However, the inability to effectively visualize these relationships has led to DNNs being characterized as black boxes and consequently limited their applications. To ameliorate this problem, we introduce the use of hierarchical interpretations to explain DNN predictions through our proposed method, agglomerative contextual decomposition (ACD). Given a prediction from a trained DNN, ACD produces a hierarchical clustering of the input features, along with the contribution of each cluster to the final prediction. This hierarchy is optimized to identify clusters of features that the DNN learned are predictive. Using examples from Stanford Sentiment Treebank and ImageNet, we show that ACD is effective at diagnosing incorrect predictions and identifying dataset bias. Through human experiments, we demonstrate that ACD enables users both to identify the more accurate of two DNNs and to better trust a DNNu0027s outputs. We also find that ACDu0027s hierarchy is largely robust to adversarial perturbations, implying that it captures fundamental aspects of the input and ignores spurious noise.",

"title": "Pseudo likelihood estimation in network tomography",
"abstract": "Network monitoring and diagnosis are key to improving network performance. The difficulties of performance monitoring lie in today's fast growing Internet, accompanied by increasingly heterogeneous and unregulated structures. Moreover, these tasks become even harder since one cannot rely on the collaboration of individual routers and servers to directly measure network traffic. Even though the aggregatory nature of possible network measurements gives rise to inverse problems, existing methods for solving inverse problems are usually computationally intractable or statistically inefficient. In this paper, a pseudo likelihood approach is proposed to solve a group of network tomography problems. The basic idea of pseudo likelihood is to form simple subproblems and construct a product of marginal likelihood of subproblems by the ignoring their dependences. As a result, it keeps a good balance between the computational complexity and the statistical efficiency of the parameter estimation. Some statistical properties of the pseudo likelihood estimator, such as consistency and asymptotic normality, are established. A pseudo expectation-maximization (EM) algorithm is developed to maximize the pseudo log-likelihood function. Two examples with simulated or real data are used to illustrate the pseudo likelihood proposal: (1) internal link delay distribution inference through multicast end-to-end measurements; (2) origin-destination matrix estimation through link traffic counts.",

"abstract": " We study the asymptotic properties of Lasso+mLS and Lasso+Ridge under the sparse high-dimensional linear regression model: Lasso selecting predictors and then modified Least Squares (mLS) or Ridge estimating their coefficients. First, we propose a valid inference procedure for parameter estimation based on parametric residual bootstrap after Lasso+mLS and Lasso+Ridge. Second, we derive the asymptotic unbiasedness of Lasso+mLS and Lasso+Ridge. More specifically, we show that their biases decay at an exponential rate and they can achieve the oracle convergence rate of $s/n$ (where $s$ is the number of nonzero regression coefficients and $n$ is the sample size) for mean squared error (MSE). Third, we show that Lasso+mLS and Lasso+Ridge are asymptotically normal. They have an oracle property in the sense that they can select the true predictors with probability converging to 1 and the estimates of nonzero parameters have the same asymptotic normal distribution that they would have if the zero parameters were known in advance. In fact, our analysis is not limited to adopting Lasso in the selection stage, but is applicable to any other model selection criteria with exponentially decay rates of the probability of selecting wrong models.

"title": "Optimal Subsampling Approaches for Large Sample Linear Regression",
"abstract": " A significant hurdle for analyzing large sample data is the lack of effective statistical computing and inference methods. An emerging powerful approach for analyzing large sample data is subsampling, by which one takes a random subsample from the original full sample and uses it as a surrogate for subsequent computation and estimation. In this paper, we study subsampling methods under two scenarios: approximating the full sample ordinary least-square (OLS) estimator and estimating the coefficients in linear regression. We present two algorithms, weighted estimation algorithm and unweighted estimation algorithm, and analyze asymptotic behaviors of their resulting subsample estimators under general conditions. For the weighted estimation algorithm, we propose a criterion for selecting the optimal sampling probability by making use of the asymptotic results. On the basis of the criterion, we provide two novel subsampling methods, the optimal subsampling and the predictor- length subsampling methods. The predictor-length subsampling method is based on the L2 norm of predictors rather than leverage scores. Its computational cost is scalable. For unweighted estimation algorithm, we show that its resulting subsample estimator is not consistent to the full sample OLS estimator. However, it has better performance than the weighted estimation algorithm for estimating the coefficients. Simulation studies and a real data example are used to demonstrate the effectiveness of our proposed subsampling methods. ",

"abstract": "This paper proposes methods for combining cepstral and acoustic waveform representations for a front-end of support vector machine (SVM)-based speech recognition systems that are robust to additive noise. The key issue of kernel design and noise adaptation for the acoustic waveform representation is addressed first. Cepstral and acoustic waveform representations are then compared on a phoneme classification task. Experiments show that the cepstral features achieve very good performance in low noise conditions, but suffer severe performance degradation already at moderate noise levels. Classification in the acoustic waveform domain, on the other hand, is less accurate in low noise but exhibits a more robust behavior in high noise conditions. A combination of the cepstral and acoustic waveform representations achieves better classification performance than either of the individual representations over the entire range of noise levels tested, down to - 18-dB SNR.",

"title": "Boosting with Early Stopping: Convergence and Consistency",
"abstract": "Boosting is one of the most significant advances in machine learning for classification and regression. In its original and computationally flexible version, boosting seeks to minimize empirically a loss function in a greedy fashion. The resulting estimator takes an additive function form and is built iteratively by applying a base estimator (or learner) to updated samples depending on the previous iterations. An unusual regularization technique, early stopping, is employed based on CV or a test set. This paper studies numerical convergence, consistency and statistical rates of convergence of boosting with early stopping, when it is carried out over the linear span of a family of basis functions. For general loss functions, we prove the convergence of boosting's greedy optimization to the infinimum of the loss function over the linear span. Using the numerical convergence result, we find early-stopping strategies under which boosting is shown to be consistent based on i.i.d. samples, and we obtain bounds on the rates of convergence for boosting estimators. Simulation studies are also presented to illustrate the relevance of our theoretical results for providing insights to practical aspects of boosting. As a side product, these results also reveal the importance of restricting the greedy search step-sizes, as known in practice through the work of Friedman and others. Moreover, our results lead to rigorous proof that for a linearly separable problem, AdaBoost with epsilon -> 0 step-size becomes an L-1-margin maximizer when left to run to convergence.",

"title": "Cloud Detection over Snow and Ice Using MISR Data",
"abstract": "Clouds play a major role in Earth's climate and cloud detection is a crucial step in the processing of satellite observations in support of radiation budget, numerical weather prediction and global climate model studies. To advance the observational capabilities of detecting clouds and retrieving their cloud-top altitudes, NASA launched the Multi-angle Imaging SpectroRa- diometer (MISR) in 1999, which provides data in nine difierent views of the same scene using four spectral channels. Cloud detection is particularly di-cult in the snow- and ice-covered po- lar regions and availability of the novel MISR angle-dependent radiances motivates the current study on cloud detection using statistical methods. Three schemes using MISR data for polar cloud detection are investigated in this study. Using domain knowledge, three physical features are developed for detecting clouds in daylight polar regions. The features measure the correlations between MISR angle-dependent radiances, the smoothness of the re∞ecting surfaces, and the amount of forward scattering of radiances. The three features are the basis of the the flrst scheme, called Enhanced Linear Correlation Matching Classiflcation (ELCMC). The ELCMC algorithm thresholds on three features and the thresholds are either flxed or found through the EM algorithm based on a mixture of two 1-dim Gaussians. The ELCMC algorithm results are subsequently used as training data in the development of two additional schemes, one Fisher's Quadratic Discriminate Analysis (ELCMC-QDA) and the other a Gaussian kernel Support Vector Machine (ELCMC-SVM). For both QDA- and SVM- based experiments two types of inputs are tested, the set of three physical features and the red radiances of the nine MISR cameras. All three schemes are applied to two polar regions where expert labels show that the MISR operational cloud detection algorithm does not work well, with a 53% misclassiflcation rate in one region and a 92% nonretrieval rate in the other region. The ELCMC algorithm produces misclassiflcation rates of 6.05% and 6.28% relative to ex- pert labelled regions across the two polar scenes. The misclassiflcation rates are reduced to approximately 4% by ELMCM-QDA and ELCMC-SVM in one region and approximately 2% in the other. Overall, all three schemes provided signiflcantly more accurate results and greater spatial coverage than the MISR operational stereo-based cloud detection algorithm. Compared with ELCMC-QDA, ELCMC-SVM is more robust against mislabels in the ELCMC results and provide slightly better results, but it is computationally slower.",

"abstract": "In situ hyperspectral data measured above sunlit and shaded sides of canopies using a high spectral resolution radiometer were analyzed for identification of six conifer tree species. An artificial neural network algorithm was assessed for the identification purpose. Linear discrimination analysis was compared with the neural network algorithm. The hyperspectral with the neural data were further processed to smoothed reflectance and first derivative spectra and were separately used in tree species identification. Tree species recognition with data collected front six study sites was tested in seven experiments. The average accuracy of species recognition was obtained at every site. The overall performance of the neural network algorithm was better than that of linear discriminant analysis for species recognition when the same number of training samples and test samples were used. The discriminant analysis produced better accuracy than neural network at one site where many samples (10) were taken from six individual trees. Use of the average spectra of all samples for a particular tree species in training may not result in higher accuracy than use of individual spectral samples in training. Use of sunlit samples alone resulted in an overall accuracy of greater than 91%. The effects of site background including illuminating conditions on tree species specra were large. Neural networks are sensitive to subtle spectral details and can be trained to separate samples front the same species at different sites. Our experiments indicate that the discriminating power of visible bands is stronger than that of near-infrared bands. Higher recognition accuracies can be obtained in the blue to green or the red-edge spectral region as compared with four other spectral regions. A smaller set of selected bands can generate more accurate identification than all spectral bands.",

Directed relationships lead to a new type of clustering that is not feasible in undirected graphs. We propose a spectral co-clustering algorithm called di-sim for asymmetry discovery and directional clustering. A Stochastic co-Blockmodel is introduced to show favorable properties of di-sim. To account for the sparse and highly heterogeneous nature of directed networks, di-sim uses the regularized graph Laplacian and projects the rows of the eigenvector matrix onto the sphere. A nodewise asymmetry score and di-sim are used to analyze the clustering asymmetries in the networks of Enron emails, political blogs, and the Caenorhabditis elegans chemical connectome. In each example, a subset of nodes have clustering asymmetries; these nodes send edges to one cluster, but receive edges from another cluster. Such nodes yield insightful information (e.g., communication bottlenecks) about directed networks, but are missed if the analysis ignores edge direction.",

"title": "Data spectroscopy: Eigenspaces of convolution operators and clustering",
"abstract": "This paper focuses on obtaining clustering information about a distribution from its i.i.d. samples. We develop theoretical results to understand and use clustering information contained in the eigenvectors of data adjacency matrices based on a radial kernel function with a sufficiently fast tail decay. In particular, we provide population analyses to gain insights into which eigenvectors should be used and when the clustering information for the distribution can be recovered from the sample. We learn that a fixed number of top eigenvectors might at the same time contain redundant clustering information and miss relevant clustering information. We use this insight to design the data spectroscopic clustering (DaSpec) algorithm that utilizes properly selected eigenvectors to determine the number of clusters automatically and to group the data accordingly. Our findings extend the intuitions underlying existing spectral techniques such as spectral clustering and Kernel Principal Components Analysis, and provide new understanding into their usability and modes of failure. Simulation Studies and experiments on real-world data are conducted to show the potential of our algorithm. In particular, DaSpec is found to handle unbalanced groups and recover clusters of different shapes better than the competing methods.",

"title": "Evaluation of a MISR-Based High-Resolution Aerosol Retrieval Method Using AERONET DRAGON Campaign Data",
"abstract": "Satellite-retrieved aerosol optical depth (AOD) can potentially provide an effective way to complement the spatial coverage limitation of a ground particulate air-pollution monitoring network such as the U.S. Environment Protection Agency's regulatory monitoring network. One of the current state-of-the-art AOD retrieval methods is the National Aeronautics and Space Administration's Multiangle Imaging SpectroRadiometer (MISR) operational algorithm, which has a spatial resolution of 17.6 km × 17.6 km. Although the MISR's aerosol products lead to exciting research opportunities to study particle composition at a regional scale, its spatial resolution is too coarse for analyzing urban areas, where the air pollution has stronger spatial variations and can severely impact public health and the environment. Accordingly, a novel AOD retrieval algorithm with a resolution of 4.4 km × 4.4 km has been recently developed, which is based on hierarchical Bayesian modeling and the Monte Carlo Markov chain (MCMC) inference method. In this paper, we carry out detailed quantitative and qualitative evaluations of the new algorithm, which is called the HB-MCMC algorithm, using recent AErosol RObotic NETwork (AERONET) Distributed Regional Aerosol Gridded Observation Networks (DRAGON) campaign data obtained in the summer of 2011. These data, which were not available in a previous study, contain spatially dense ground measurements of the AOD and other aerosol particle characteristics from the Baltimore-Washington, DC region. Our results show that the HB-MCMC algorithm has 16.2% more AOD retrieval coverage and improves the root-mean-square error by 38.3% compared with the MISR operational algorithm. Our detailed analyses with various metrics show that the improvement of our scheme is coming from the novel modeling and inference method. Furthermore, the map overlay of the retrieval results qualitatively confirms the findings of the quantitative analyses.",

"title": "Hourglass multimedia content and service composition framework for smart room environments",
"abstract": "Pervasive environments with their ubiquitous multimedia devices such as video-enabled cell-phones, laptops, PC tablets, digital cameras, HDTV plasma displays are becoming integral part of our workplaces and homes. Furthermore, these digital multimedia devices make it easier and easier to create and view volumes of content that can be stored throughout the Internet. The big challenge is to organize the distributed content, get the distributed multimedia content composed, produced and distributed to users in customized fashion according to users' preference, and their resource availabilities in pervasive environments. Basically, the challenge is to create Internet Interactive Television where the user/interest group, residing in a pervasive environment, corresponds to the TV program director who decides and/or influences what content(s) will be viewed, how it will be composed, presented and delivered. In this paper, we present a vision how this challenge can be solved. We propose a novel hourglass-based system that delivers composite multimedia content to users in pervasive environments, which considers both users' interest in the content and the presentation capabilities of various display devices. This hourglass-based system relies on our content and service composition framework that allows for customized production, distribution and presentation of multimedia content for pervasive environments. We present the hourglass design, possible solutions for some content composition scenarios and validate the solutions via selected experiments.",

"title": "A Three-Layer Virtual Director Model for Supporting Automated Multi-Site Distributed Education",
"abstract": "In multi-site distributed education (MSDE), video streams from multiple sites are available. To best utilize the limited screen space at each site, we develop a customizable, automated display man- agement system in this paper, i.e., only user-preferred streams will be shown as triggered by events and timers. The configuration of such user preference, however, is challenging because it has to be both human-friendly and machine-friendly. To address this chal- lenge, we propose a three-layer virtual director model. In the user layer, we identify three categories of parameters that can represent a wide range of user preferences yet are easy to use. These prefer- ences are then automatically translated into a machine-friendly timed automaton in the execution layer. The automaton is simu- lated dynamically, which selects a subset of streams to show on the screen through a display layer. Evaluation results demonstrate the correctness and efficiency of the proposed framework.",

"title": "Myview: customizable automatic visual space management for multi-stream environment",
"abstract": "Recent years witnessed the emergence of more \"multi-stream\" Multimedia applications, such as multi-site distributed video conferencing, multi-perspective IPTV, and virtual touring of 3D digital worlds from multiple view points, etc.In this work, we study the problem of visual space management in such applications. The key observation is that there are multiple visual streams that need to be presented to the users, while the visual space is limited both by availability of physical display devices and by user's visual attention space. We argue that the visual space is a type of critical resource that requires careful management in similar way as other resources (such as CPU cycles and memory slots). Specifically, the unique challenges are how to model the visual streams and the viewers' preference among them, how to determine which of these visual streams should be presented to the viewer, and how the output windows of these selected streams should be arranged on the display devices.Many existing systems have explored the solution space from different perspectives, but none of them provide a solution that is customized to user interest, automatic to avoid unnecessary user input, and yields high visual quality screen output. In this work, we introduce a 3-phase visual space management framework called MyView that makes the following three key contributions. First, a generic shot-based visual stream model and a score-based viewer interest model are designed to represent user interest, which lays the foundation for automatic visual space management decisions. Second, an automatic stream selection algorithm is developed that maintains a timed automaton to calculate which visual streams should be selected for display. Third, a screen layout calculation algorithm is designed to compute the screen layout for presenting the selected visual stream(s) on one or multiple display devices in a visual pleasing way that maximizes screen space utilization.We have built a lecture recording and broadcasting system on top of the ConferenceXP platform to evaluate our solution. Results from both simulation experiments and user study have confirmed the functional correctness and usability of the MyView framework.",

"title": "A multi-stream adaptation framework for bandwidth management in 3D tele-immersion",
"abstract": "Tele-immersive environments will improve the state of collaboration among distributed participants. However, along with the promise a new set of challenges have emerged including the real-time acquisition, streaming and rendering of 3D scenes to convey a realistic sense of immersive spaces. Unlike 2D video conferencing, a 3D tele-immersive environment employs multiple 3D cameras to cover a much wider field of view, thus generating a very large volume of data that need to be carefully coordinated, organized, and synchronized for Internet transmission, rendering and display. This is a challenging task and a dynamic bandwidth management must be in place. To achieve this goal, we propose a multi-stream adaptation framework for bandwidth management in 3D tele-immersion. The adaptation framework relies on the hierarchy of mechanisms and services that exploits the semantic link of multiple 3D video streams in the tele-immersive environment. We implement a prototype of the framework that integrates semantic stream selection, content adaptation, and 3D data compression services with user preference. The experimental results have demonstrated that the framework shows a good quality of the resulting composite 3D rendered video in case of sufficient bandwidth, while it adapts individual 3D video streams in a coordinated and user-friendly fashion, and yields graceful quality degradation in case of low bandwidth availability.",

"title": "Optimizing Visible Objects Embedding Towards Realtime Interactive Internet TV",
"abstract": "Embedding new visible objects such as video or images into MPEG video has many applications in newscasting, pay- per-view, Interactive TV and other distributed video ap- plications. Because the embedded foreground content in- terferes with the original motion compensation process of the background stream, we need to decode macroblocks in I and P frames via motion compensation and re-encode all macroblocks with broken reference links via motion re- estimation. Although previous work has explored DCT- compressed domain algorithms and provided a heuristic ap- proach for motion re-estimation, the computation intensive motion compensation step is not much optimized and so still prevents efficient realtime embedding. In this work, we optimize previous work to enable realtime embedding processing that can be applied to Interactive Internet TV applications. We study the motion compensation process and show that on average up to 90% of the macroblocks decoded are not used at all. To explore this phenomenon, we propose to buffer a GOP (Group-Of-Picture) of frames and apply a backtracking process that identifies the minimum set of macroblocks which need to go through the decoding operation. At the price of a delay of one-GOP time, this ap- proach greatly speeds up the whole embedding process and enables on-line software embedding operation even capable for processing HDTV stream. Further optimizations are discussed and a real-world application scenario is presented. Experimental results have confirmed that this approach is much more efficient than previous solutions and results in equally good video quality.",

"abstract": "Service composition is highly desirable in peer-to-peer (P2P) systems where application services are naturally dispersed on distributed peers. However, it is challenging to provide high quality and failure resilient service composition in P2P systems due to the decentralization requirement and dynamic peer arrivals/departures. We present an integrated P2P service composition framework called SpiderNet to address the challenges. At service setup phase, SpiderNet performs a novel bounded composition probing protocol to provide scalable quality-aware and resource-efficient sendee composition in a fully distributed fashion. Moreover, SpiderNet supports directed acyclic graph composition topologies and explores exchangeable composition orders for enhanced service quality. During service runtime, SpiderNet provides proactive failure recovery to overcome dynamic changes (e.g., peer departures) in P2P systems. The proactive failure recovery scheme maintains a small number of dynamically selected backup compositions to achieve quick failure recovery for soft realtime streaming applications. We have implemented a prototype of SpiderNet and conducted extensive experiments using both large-scale simulations and wide-area network testbed. Experimental results show the feasibility and efficiency of the SpiderNet service composition solution for P2P systems.",

One important question is how to organize the large amount of visual data, being captured, processed, transmitted and displayed, and their corresponding resources, over current COTS computing and networking infrastructures so that \"everybody\" would be able to install and use tele-immersive environments for conferencing and other activities. In this paper we propose a novel crosslayer control and streaming framework over general purpose delivery infrastructure, called TEEVE (Tele-immersive Environments for EVErybody). TEEVE aims for effective and adaptive coordination, synchronization, and soft QoSenabled delivery of tele-immersive visual streams to remote room(s). The TEEVE experiments between two teleimmersive rooms residing in different institutions more than 2000 miles apart show that we can sustain communication of up to 12 3D video streams with 4~5 3D frames per second for each stream, yielding 4~5 tele-immersive video rate.",

Traditional video summarization techniques are based on low-level feature analysis, which generally fails to capture the semantics of video content. Our vision is that users unintentionally embed their understanding of the video content in their interaction with computers. This valuable knowledge, which is difficult for computers to learn autonomously, can be utilized for video summarization process. In this paper, we present an intelligent video browsing and summarization system that utilizes previous viewers' browsing log to facilitate future viewers. Specifically, a novel ShotRank notion is proposed as a measure of the subjective interestingness and importance of each video shot. A ShotRank computation framework is constructed to seamlessly unify low-level video analysis and user browsing log mining. The resulting ShotRank is used to organize the presentation of video shots and generate video skims. Experimental results from user studies have strongly confirmed that ShotRank indeed represents the subjective notion of interestingness and importance of each video shot, and it significantly improves future viewers' browsing experience.",

"abstract": "Many features of traditional TV service are becoming desirable for software multimedia applications to provide open solutions and improve flexibility. In this work, we have studied a new kind of service, what we call \"visual information embedding\", that comes from the idea of Picture-In-Picture. Based on previous work in MPEG-compressed domain algorithms, we propose a \"backtrack- ing\" approach that reduces the decoding complexity up to 90% and enables realtime processing on MPEG2 streams at the price of a delay of one Group-Of-Picture period. We have implemented a software realtime visual information embedding gateway for HDTV streams, and the experimental results have shown that our solution is practical and efficient.",

"abstract": "With the increasing demand and popularity of multimedia streaming applications over the current Internet, manipulating MPEG streams in a real-time software manner is gaining more and more importance. In this work, we studied the synchronization problem that arises when a gateway changes the data content carried in an MPEG2 Transport stream. In short, the distance between original time stamps will be changed non-uniformly when the video frames are resized, and decoders will fail to reconstruct the encoding clock from the resulting stream. We propose a cheap software real-time approach to solve this problem, which basically reuses the original time stamp packets and adapts their distance to accommodate the changes in bit rate. Experimental results from a real-time HDTV stream filter shows that our approach is correct and efficient.",

In this paper, a new method of transmission fluctuation spectrometry with signal correlation is presented, whereby the beam diameter is assumed to be much less than the particle diameter. The transmission fluctuations are expressed in terms of the expectancy of the transmission product (ETP) and are obtained as a spectrum with respect to the variable correlation time.

In Gregory’s method, the beam diameter is required to be much larger than the particle diameter, which limits the application seriously. In this work, we introduce a new method of the transmission fluctuation measurement, in which the beam diameter can be less, equal to and larger than the particle diameter. The theoretical analysis proves that, when the beam-to-particle diameter ratio is within the range of 0.05 and 10, the new method is able to achieve satisfying measurement results. However, Gregory’s method is only suitable in the range of 5 and 10. Therefore, this new method enhances the transmission fluctuation measurements greatly.",

Based on the assumption of low particle concentrations, an analytical expression of the transmission fluctuation correlation spectrum can be obtained with a layer model. It is found that the measurement matches the theory very well as long as the particle concentration is low enough. However, as the particle concentration increases, the measured transmission fluctuation spectrum deviates gradually from the theory, which is a result of the high concentration effects. High concentration effects include particle overlapping and monolayer structure. In this work, theory and simulations on particle overlapping are studied. As a result, an empirical expression is found. © Taylor & Francis Group, LLC.",

With simple optical arrangement and easy operation, the method can be applied to real-time, online measurements. The transmission signal with fluctuations are analyzed by using a second order low pass filter (LPF), and the experimental data of transmission fluctuation spectra in the frequency domain are obtained. The particle size distributions and concentrations are extracted from the experimental data with the modified Chahine iterations. Effects on the spectra of transmission fluctuations of the high concentration are discussed. The high concentration correction includes frequency response to characteristic function and step height of the transition function. Parameters for the high concentration correction are achieved and further employed in the inversion algorithm, and reasonable measurement results are obtained. Analysis to the measurement data shows that, with the high-concentration correction, the particle size distribution and particle concentration can be recovered within a broad dynamic range and the largest measurable particle volume concentration depends on the particle size.",

Experiments are realized in a focused Gaussian beam and the acquisition of transmission signals is achieved by using a high-resolution digital oscilloscope.

"title": "A dynamic approach to detecting, eliminating and fixing memory leaks",
"abstract": "This paper presents a dynamic approach to detecting, eliminating and fixing memory leaks. With our approach, a program to be analyzed is instrumented before its execution. Dynamic symbolic execution is employed so as to expose memory leaks occurring in all execution paths. During the program execution, information about each allocated memory area is updated when corresponding statements are executed. Based on this information, a back-end leak checker records the changes of variables pointing to each memory area, detects memory leaks and deallocates leaked memory areas. After the program execution, a fixed program containing deallocation statements is generated. We have implemented our approach in a tool called DEF_LEAK based on Low Level Virtual Machine compiler infrastructure. Experiments show that DEF_LEAK can detect more leaks than the existing dynamic detection tools for programs with user inputs. Moreover, DEF_LEAK is more effective for helping programmers understand and fix memory leaks than other detection tools. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.",

"title": "Verifying temporal properties of programs: A parallel approach.",
"abstract": "Abstract Due to the nature in dealing only with observed executions of a real system, runtime verification is being pursued as a lightweight verification technique. However, the overhead for analyzing the desired temporal properties usually degrades performance greatly. The reasons are: (1) the low efficiency of the interpretive execution in the analyzing process, and (2) nondeterminism of the automata generated from temporal logic properties. To overcome them, this paper presents a parallel approach to verify full regular temporal properties of a program. With this approach, the program is written in Modeling, Simulation and Verification Language (MSVL), and the property is specified by a Propositional Projection Temporal Logic (PPTL) formula. Execution and verification of a program are carried out at the same time. Specifically, each trace generated from executing a program is divided into several segments which are verified in parallel. Also, in the process of verifying each segment, nondeterministic choices in the relative automaton of a temporal property are also handled in parallel. Finally, verification results of all the segments are merged to form the eventual result as well as the counterexample. Our parallel mechanism takes full advantage of the hardware resources and makes temporal property verification efficient in a multi-core system. Experiments show that our approach is practical in verifying temporal properties of large-scale programs in the real world.",

"title": "Semantic matching of web services for collaborative business processes",
"abstract": "It is a prerequisite for automating business processes integration to dynamically discover usable web services. A formal approach to semantic matching of web services based on choreographies is presented to support it. First, an extended deterministic finite automaton (EDFA) is proposed by labeling state transitions with binary-tuples (input, output) rather than letters. EDFAs represent services more accurately: the nodes represent the states maintained by the service; the state transitions represent the communication activities of the service. Thus, the automata depicts the temporal sequences of communication activities that describe the behavior of services. Second, the semantics-based intersection of EDFAs is presented and the compatibility of services is evaluated by testing the emptiness of the languages accepted by EDFAs. Finally, component structures are introduced to describe services with two roles: invoking another service and/or being invoked by another service. The compatibility of services can be employed to discover usable services, moreover, to validate collaborative business processes.",

However, the issue of behavior compatibility is still not properly solved. In this paper, we propose a choreography-based formal approach to discover semantic web services that are compatible with their behaviors. The fuzzy petri net is used to perform the modeling, verification, analysis and evaluation for the matchmaking of semantic web services. The requested and provided services are modeled by two fuzzy petri nets combined through a set of combination rules. By analyzing the composite fuzzy petri net, the behavior compatibility can be verified, and the matching degree between requested and provided services can be obtained. With our approach, the success rate and accuracy of the semantic web services discoveries can be improved, and the final services set can be optimized.",

"abstract": "Many group debris flow hazards were triggered by subsequent rainstorm in the Wenchuan Earthquake area after the main shock.Group debris flow hazards in Longchi,Dujiangyan,Sichuan Province is one of these disasters.There were 45 debris flows triggered by heavy rainfall in the catchment of Longxi River on August 13,2010.In the all 45 debris flows,there were 34 channelized debris flows and 11 debris flows on the slope.The total volume of debris flow was 3.34×106 m3 and plenty of sediment was deposited in the downstream of Longxi River.The rainfall which triggered the debris flows in Longxi River catchment on August 13,2010 was 75 mm in one hour.It was the same as one hour rainfall of twenty years return period.Most debris flows were distributing in 3 km from the triggering belt of Wenchuan Earthquake,only 11.1% of total debris flows were located in 3-5 km from the triggering belt.The distribution of debris flows were also controlled by the rock characteristics and geomorphology.Most of debris flows are viscous debris flows,only 11.1% of total debris flows were less viscous debris flows.There were 60.0% small scale debris flows and 11.1% large scale debris flows in total debris flows.Most catchments of debris flow were small catchment,68.9% of total catchments was less than 1 km2,only 6.7% of total catchments was larger than 3 km2.The sediment deposited in Longxi River was controlled by the activity of debris flows,the width of channel,and the slope of channel: there was no sediment deposited in the upper stream of Longxi River,but there was plenty of sediment deposited in the downstream.The size of sediment deposited in Longxi River was partly decided by the rock characteristics of debris flow catchments,as the results the particle sizes were decreasing from upper stream to downstream of Longxi River.The debris flow hazards will be triggered again when it is heavy rainfall in Longxi River catchment.To reduce the hazards of debris flows in the Wenchuan Earthquake area,forecast and prevention work must be done in the next raining season.",

The aggradations of floods and debris flows are common environmental problems in fault lakes in southwestern China. Investigating the background of the basin of Goose Foot River, the effect of human activities on Lake Qionghai, Sichuan Province, China, and the underwater topography maps of 1988 and 2003 were analyzed. In the past 30 years, turbidity currents were formed by debris flows and floods of Goose Foot River and took huge sediment into Lake Qionghai. The sediment not only pushed the coastline of Lake Qionghai at Goose Foot River fan into lake, but also deposited in the lake to the opposite bank. Debris flows took much more sediment into Lake Qionghai than the soil erosion did in the same basin. There is an underwater levee on the underwater fan. The underwater levee is 2 km in length, 200 m ( at south coast) to 600 m (at north coast) in width and the average 2 m in height. The maximum height of sediment deposition at underwater levee is 8. 29 m, or 0. 55 m for every year. There is a channel on the slope of the underwater fan of Goose Foot River mouth eroded by turbidity currents. The main source of sediment is the sediment token by the debris flows in 1996, 1997 and 1998. It should be paid more attention on the environment issues,such as basic characteristics, underwater topography of Lake Qionghai and the effect of Goose Foot River debris flows on Lake Qionghai.",

To find out the critical velocity of flood for initiating debris flow,experiments of critical hydraulic conditions for initiating particles and debris flows were conducted in the laboratory. The conclusions are that the critical condition of initiation of debris flow is between the conditions of initiation of a little particle and abundance particle. The probability of critical initiation is 0. 05,two times as much as the probability of initiation of a little particle,one third of initiation probability of abundance particle. The critical velocity of initiation of particle and debris flow increases with the median particle size and asymmetrical coefficient of sediment. It decreases with the bed slope. The revised equation of initiating velocity of particle and debris flow can be used in the calculation of initiating velocity of coarse particle and large asymmetrical coefficient of sediment.",

"abstract": "Viscous debris flows is the most regular and dangerous debris flows.The velocity of debris flow is the most important parameter in the dynamics parameter of debris flow.It is very important to calculate the velocity of viscous debris flow exactly and easily.The resistance of debris flow is quite different at different area: high resistance of debris flow area with low velocity;low resistance of debris flow area with high velocity.All equations of velocity of viscous debris flow at present are not good at all kinds of resistance area.The asymmetric coefficients of debris flows are quite different in different area: large asymmetric coefficients of debris flow with low resistance;small asymmetric coefficients of debris flow with high resistance.The asymmetric coefficients of debris flow could be used to classify resistance characteristics of debris flow accurately and the resistance law of viscous debris flows was got by asymmetric coefficients.By a series field observation data,an empirical equation of mean velocity of viscous debris flow was got.The velocity calculated by the asymmetric coefficients,bottom slope and hydraulic radius of flow.It is good at both high resistance and low resistance area of debris flows.It is good consistent for the measuring velocity of otherwise field observation data of debris flow and viscous mudflow by this empirical equation.The Froude number of flow is the factor of flow status: supercritical flow or subcritical flow.Ordinary viscous debris flows are supercritical flows,minorities are subcritical flows,and few are slow-motion debris flows which have too large density.The empirical equation is excellent at ordinary supercritical viscous debris flow,but it is bad for the slow-motion flow with large density of debris flow,and it is gentle large for the subcritical viscous debris flow.In the evaluation and prevention of debris flows,the mean velocity equation could be used for the velocity calculated of viscous debris flow in the channel at the upstream of the debris flow fans.At the same time,it is gentle large for the calculating the velocity of viscous debris flow on the debris flow fans.It is bad for the slow-motion debris flow,but the slow-motion could be ignored in the evaluation and prevention of debris flows.",

"abstract": "The particle distribution of the deposition of less viscosity debris flow is not the real particle distribution as the sorting of less viscosity of debris flow. The deposition of transitional debris flow is close to its real particle distribution as the transitional debris flow is weak sorting. Comparing the particle distributions of depositions of less viscosity and transitional debris flows with their real particle distributions,we get the fine particle is the main part of less viscosity debris flow,and the percentage of >5 mm is small. Most percentages of coarse particles in less viscosity debris flows are aggrandized. To correct the aggrandized percentage of coarse particle in less viscosity debris flow,delete the coarse part of >5 mm is necessary. The real densities of less viscosity debris flows are good consistency with the densities calculated by the corrected particle distributions and improved equation. To correct the aggrandized percentage of coarse particle in transitional debris flow,delete the coarse part of >20 mm is necessary. The real densities of transitional debris flows are better consistency with the densities calculated by the corrected particle distributions.",

"title": "Ultrasound-surfactant synergistic extraction of saponins from balsam pear",
"abstract": "Balsam pear (Momordica charantia L.), a climber belonging to family Cucurbitaceae, is commonly known as bitter gourd or bitter melon in English. It is cultivated throughout the world for use as vegetable as well as medicine. Balsam pear has been used traditionally as medicine in developing countries. Some of its common uses in most countries are for diabetes, a carminative and in treatment of colics. Topically it is used for treatment of wounds, internally as well as externally for management of worms and parasites. It is also used as emmenagogue, antiviral for measles and hepatitis. Balsam pear contains biologically active chemicals that include glycosides, saponins, alkaloids, fixedoils, triterpenes. Saponins from all parts of the plant (fruit pulp, seed, leaves and whole plant) are most widely studied with regard to its antidiabetic effect. Ultrasound and surfactants have been individually shown to enhance saponins extraction. In this study, we investigated the synergistic effect of ultrasound and surfactants on saponins extraction. In order to explore effective extracting method of saponins from balsam pear, response surface was used to study the effect of ultrasonic power (133-167 W/g), ethanol volume fraction (60%-80%) and mass concentrations of SDS (15-25 mg/mL) on extraction rate of saponins from balsam pear. Ultrasound-surfactant synergistic extraction was compared with ethanol and ultrasound, respectively. The structures of the prepared saponins from balsam pear were identified. Results showed that the established model of extraction could well predict extraction rate of saponins from balsam pear under different conditions. Extraction rate of saponins from balsam pear was significantly (p<0.05) influenced by ultrasonic power, ethanol volume fraction and mass concentrations of SDS, and there was synergistic effect between ultrasonic power and the mass concentration of SDS. Various factors affecting extraction rate of saponins from balsam pear in a descending order was as follows: mass concentrations of SDS, ultrasonic power, ethanol volume fraction. Extraction rate of saponins from balsam pear was 3.22% at ultrasonic power of 153 W/g, ethanol volume fraction of 74%, mass concentrations of SDS of 16 mg/mL, significantly higher (p<0.05) than that of ethanol and ultrasound extraction. Liquid chromatography-mass spectrometry revealed that extracted saponins included momordicoside L and F2 . Ultrasound-surfactant synergistic extraction is an effective method for extraction of saponins, which is worth further development and application.",

Contrary to structured illumination microscopy (SIM), SRFB considers the time-varying fluorescence distribution under a suitable density as the varying illuminated speckle pattern, and therefore, external speckle patterns or diffusers are not required. With several images recorded at different times, a super-resolution image can be obtained through an iterative algorithm modified from Fourier ptychography. Recorded image sequences in a microscopy imaging experiment based on photo switching or fluorescence blinking effects, such as STORM and SOFI, can be handled with SRFB and used to recover a super-resolution image. The simulation and experimental results confirm that the SRFB scheme can surpass the diffraction limit by a factor greater than two.",

However, the security of this cryptosystem has not been analyzed thoroughly from the point of view of cryptoanalysis. In this article, the weakness of Javidi's optical security system is carefully analyzed with a known-plain text attack. It is shown that the double-random-phase encoding encryption scheme is a linear symmetric block cipher cryptosystem and its linearity opens avenues of attacks. Under the known-plaintext attack, attacker can obtain the phase key (s) in the input plane using the typical phase retrieval algorithms and subsequently deduce the phase key (s) in the Fourier domain easily. In addition, an optical implementation of known-plain text attack is also proposed.",

However, for thick samples, the background brought by the crosstalk of unwanted on-state molecules is nonnegligible. Now we present a background suppression method by using two axial standing waves generated by the interference of two activation beams with the same phases and two deactivation beams with the opposite phases. With spatially incoherent illumination, most activated molecules are located in a thin layer. The performance of such method is simulated with the known photoswitching characteristic of Cy5.

"title": "Deconvolution optimization in super-resolution optical fluctuation imaging based on cumulant standard deviation",
"abstract": "The super-resolution optical fluctuation imaging (SOFI) technique enhances image spatial resolution by evaluating the independent stochastic intensity fluctuations of emitters. In principle, it eliminates any noise uncorrelated temporally, and provides unlimited spatial resolution since the calculation of the nth-order cumulant followed by a deconvolution results in an image with n-fold resolution improvement in three dimensions. But in practice, due to limited data length, the statistical uncertainty of cumulants will affect the continuity and homogeneity of SOFI image, which results in the fact that the high order SOFI (typically over 3rd order) cannot improve spatial resolution significantly. Since the variance characterizes the statistical uncertainty of cumulant, we deduce its theoretical expression based on a single dataset. In traditional SOFI techniques, due to lack of statistical analysis of cumulant, there is no noise constraint condition of cumulant in the Lucy-Richardson deconvolution to prevent the algorithm from causing noise amplification. In this paper, based on the cumulant variance formula, we calculate the cumulant standard deviation in each pixel of SOFI image and introduce the results into the Lucy-Richardson algorithm as a DAMPAR to suppress the noise generation in such pixels. The simulation and experimental results show that under the same data length, the deconvolution optimization based on cumulant standard deviation significantly improves the uniformity and continuity of SOFI image. On the other hand, under the premise of identical image quality, this optimization technique can also greatly shorten the image frames to less than half the original, thus promoting the development of super-resolution imaging of living cells.",

"abstract": "The present authors have previously reported a novel approach to genetically engineer Salmonella typhimurium for the medically important therapeutic strategy of using bacterial agents to target malignant tumors in a breast cancer tumor-bearing nude mouse model. However, studying an immunocompromised mouse model for cancer therapy is insufficient, as certain crucial information about the influence of the immune system may be missing. In the present study, inoculation of the Salmonella strain, YB1, into a colon cancer tumor-bearing immunocompetent mouse model was investigated. The present study determined the tumor targeting efficiency, antitumor potential, the effects of multiple treatments and the systemic toxicity. Intravenous inoculation of YB1 in BALB/c mice exhibited high antitumor effects and also greatly increased the tumor targeting ability and safety compared with the previously-reported nude mouse model. In addition, repeated administration of YB1 further enhanced this effect. Furthermore, no marked toxicity was observed with YB1 treatment, while the VNP20009 and SL7207 strains demonstrated certain adverse effects. The findings of the present study indicate that the YB1 strain is effective and safe in targeting a colon cancer tumor in an immunocompetent mouse model.",

"abstract": "The super-resolution optical fluctuation imaging (SOFI) technique enhances image spatial resolution by calculating the spatiotemporal cross-cumulants of independent stochastic intensity fluctuations of emitters. Ideally, SOFI eliminates any noise that is not correlated over time, but in practice, due to limited data lengths, the statistical uncertainty of cumulants will affect the continuities and homogeneities of SOFI images. Since the variance and signal-to-noise ratio (SNR) characterize cumulant statistical uncertainty, we determined theoretical expressions for these based on a single dataset. From a simulation of temporal fluctuations of blinking fluorescent emitters, we calculated the quantitative relation between the SNR of cumulants and multiple parameters of the blinking signal, such as the on-time ratio, acquisition frame to average blinking rate ratio, sequence length, and photon amplitude, which not only provides a physical interpretation for SOFI phenomena but also theoretical guidance to achieve optimal practical outcomes.

"abstract": "The combination of switch effect and single molecule positioning can realize the sample super diffraction resolution imaging, and double helix point spread function will be a single molecular orientation nanometer resolution extending from two dimensions to three dimensions. In this paper, three-dimensional (3D) positioning accuracy of the double helix point spread function is discussed. First, the theoretical localization accuracy for an unbiased estimator of the double-helix point spread function is compared with that for 3D localization using Fisher information and the influences of localization accuracy including photon number, varying levels of background and pixel size are analyzed. Second, based on the localization algorithm of gaussian fitting, which is usually adopted in data analysis of single molecular orientation in the experimental process, the axial localization accuracy of double helix point spread function is obtained by the error transfer function law. Computer simulation results show that under the condition of more than 1000 photons in number, the positioning accuracy of gaussian fitting localization algorithm and theory localization accuracy of Fisher information are in good agreement. The discussion of the paper provides not only the theoretical basis for 3D positioning accuracy of double helix point spread function, but also the theoretical guidance for the experiment at the same time.",

The critical component in DDCM is a custom designed composite phase mask (PM) combining the functions of DG and DH-PSF. The localization precision and the effective DOF of the home-built DDCM system based on the designed PM were tested. Our experimental results show that the three-dimensional (3D) localization precision for the three diffraction orders of the grating are σ(-1st)(x, y, z) = (6.5 nm, 9.2nm, 23.4 nm), σ(0th)(x, y, z) = (3.7 nm, 2.8nm, 10.3 nm), and σ(+1s)(x, y, z) = (5.8 nm, 6.9 nm, 18.4 nm), respectively. Furthermore, the total effective DOF of the DDCM system is extended to 14 μm.

"abstract": "In our novel structured illumination microscope (SIM), a programmable digital micromirror device (DMD) was used instead of piezo activated grating to produce stable and reliable structured illumination. An optical low-pass spatial filter was applied to block the diffraction order higher than ±1st order. The illumination pattern was not a sinusoidal grid with a single spatial frequency, so the algorithm used in the traditional SIM is not proper here. An improved algorithm based on the five raw images with different phase angles was introduced and discussed in detail. The results have demonstrated that the sectioned image can be reconstructed from five raw images with different phase angles, with resolving some fine lateral structure that was blurred in traditional microscopic image.",

The phase of the products was determined by means of x-ray diffraction, and the morphology and structure were characterized by using scanning electron microscopy, transmission electron microscopy, high resolution transmission electron microscopy and selected area electron diffraction techniques. The growth direction of the KNb3O8 obtained was determined to be the [001] crystallographic direction. Meanwhile, the polarization response of the second-harmonic generation (SHG) response was investigated. The as-synthesized nanowires clearly exhibited a SHG response, which means that the nanowires were an efficient nanoscale second-harmonic light source. The excellent nonlinear optical property of KNb3O 8 shows potential for application in nano-optical devices. © 2013 IOP Publishing Ltd.",

A special phase mask, combining the field depth extension capabilities of DG with the three-dimensional (3D) nanolocalization capabilities of the DH-PSF, is designed for multiparticle parallel localization. Time-lapse tracking of one particle moving along the z axis and parallel tracking of two particles are simulated. Results demonstrate that, with only a single snapshot, particles can be localized, tracking with 3D nanoresolution wherever they are. The theoretical localization precisions of DDCM, DH-PSF, and multifocus microscopy are compared. DDCM results in almost constant localization precisions in all three dimensions for a depth of field larger than 10 μm. DDCM is expected to become a tool in investigations of important dynamic events in living cells.",

The effect of different kinds of molten salt on the structure and morphological profile of the powers were discussed, and the optical properties of the samples were studied. X-ray diffraction results showed that the product is KNb 3O 8 when the KCl and K 2SO 4 as molten salt, respectively, and the product is K 2NbO 4 when the K 2CO 3 and KNO 3 as molten salt, respectively. Scanning electron microscopy results showed that bar was formed with the width of 0.2-0.5 μm and the length of several microns. Using K 2SO 4 as molten salt, the width of rod is 0.2-1 μm and the length is 1-25 μm. Using K 2CO 3 as molten salt, the product is not rod-like structure, but irregular granular structure. Using KNO 3 as molten salt, the width of rod is 0.2-1 μm and the length is 0.5-4 μm. Part of the rod-like structure connected together. Fluorescence spectra showed that KNb 3O 8 and K 3NbO 4 crystals have good fluorescence. Fluorescence studies have shown that the samples have very similar fluorescence spectra with K 2SO 4, KNO 3 and K 2CO 3 as the molten salt. The samples have good fluorescence which were prepared using KCl, K 2SO 4 and K 2CO 3 as molten salt.",

"title": "Fast stimulated emission nanoscopy based on single molecule localization",
"abstract": "For super-resolution microscopy methods based on single molecule stochastic switching and localization, to simultaneously improve the spatial-temporal resolution, it is necessary to maximize the number of photons that can be collected from single molecules per unit time. Here, we describe a novel approach to enhance the signal intensity (collected photons per second) from fluorescence probes by introducing a stimulated emission (SE) optical process. This process is based on the following two properties: first, with reasonable parameters, the photon emission rate can be significantly increased with SE; and second, the SE photons, which are spatially coherent with the stimulation beam, are more favorable for collection than fluorescence. Theoretical results have shown that signal intensity from a single fluorescent molecule can be greatly improved with SE. We therefore showed, using SE in combination with single molecule localization methodology, that fast imaging at a rate of 0.05 s per reconstructed image with lateral resolutions of similar to 30 nm can be obtained.

"abstract": "Double helix point spread function possesses continuously rotating invariant features with defocus, and it can be used for performing nano-resolution image of thick samples and for studying singleparticle tracking by combining the single-molecule localization method. However, the inadequacy of the original double helix point spread function is that the transfer function efficiency is very low, so it is difficult to achieve photon limited applications for the bio-imaging. The double-helix point spread function is optimized by introducing an iterative algorithm so that the constraints of the point spread function can be optimized best in three different domains: the Laguerre-Gauss modal plane, the spatial domain, and the Fourier domain. The simulation results show that the peak intensity of high efficiency double helix point spread function is 30 times higher than the original one. The design and fabrication of the phase plate are also proposed. The experimental results are in good agreement with the theoretical predictions, thus proving the feasibility of this method.",

"title": "Improved localization accuracy in double-helix point spread function super-resolution fluorescence microscopy using selective-plane illumination",
"abstract": "Recently, three-dimensional (3D) super resolution imaging of cellular structures in thick samples has been enabled with the wide-field super-resolution fluorescence microscopy based on double helix point spread function (DH-PSF). However, when the sample is Epi-illuminated, much background fluorescence from those excited molecules out-of-focus will reduce the signal-to-noise ratio (SNR) of the image in-focus. In this paper, we resort to a selective-plane illumination strategy, which has been used for tissue-level imaging and single molecule tracking, to eliminate out-of-focus background and to improve SNR and the localization accuracy of the standard DH-PSF super-resolution imaging in thick samples. We present a novel super-resolution microscopy that combine selective-plane illumination and DH-PSF. The setup utilizes a well-defined laser light sheet which theoretical thickness is 1.7 mu m (FWHM) at 640nm excitation wavelength. The image SNR of DH-PSF microscopy between selective-plane illumination and Epi-illumination are compared. As we expect, the SNR of the DH-PSF microscopy based selective-plane illumination is increased remarkably. So, 3D localization precision of DH-PSF would be improved significantly. We demonstrate its capabilities by studying 3D localizing of single fluorescent particles. These features will provide high thick samples compatibility for future biomedical applications.",

However, limited depth of field is the main drawback of conventional microscopy that prevents observation and tracking of multiple molecules in intact cells. Based on the principle of wavefront coding, the design and fabrication of a novel diffractive optical element (DOE) which combines a distorted diffraction grating with a double-helix point spread function (PSF) phase plate so that it can simultaneously perform multi-plane imaging with double-helix PSF and realize an extended depth of field is presented. Experiments have been carried out on a self-built microscopic system based on the novel DOE, showing that a depth of field can be up to 12 mu m. Experimental results are in good agreement with the theoretical predictions, thus proving the feasibility of this method.",

"abstract": "A cascaded iterative angular spectrum approach (CIASA) based on the methodology of virtual optics is presented for optical security applications. The technique encodes the target image into two different phase only masks (POM) using a concept of free-space angular spectrum propagation. The two phase-masks are designed and located in any two arbitrary planes interrelated through the free space propagation domain in order to implement the optical encryption or authenticity verification. And both phase masks can serve as enciphered texts. Compared with previous methods, the proposed algorithm employs an improved searching strategy: modifying the phase-distributions of both masks synchronously as well as enlarging the searching space. And with such a scheme, we make use of a high performance floating-point Digital Signal Processor (DSP) to accomplish a design of multiple-locks and multiple-keys optical image encryption system. An evaluation of the system performance is made and it is shown that the algorithm results in much faster convergence and better image quality for the recovered image. And two masks and system parameters can be used to design keys for image encryption, therefore the decrypted image can be obtained only when all these keys are under authorization. This key-assignment strategy may reduce the risk of being intruded and show a high security level. These characters may introduce a high level security that makes the encrypted image more difficult to be decrypted by an unauthorized person.",

However, its localization precision is limited by fluorescent contrast in thick samples because the signal-to-noise ratio of the system is low due to the inherent low transfer function efficiency and background fluorescence. Here we combine DH-PSF microscopy with light-sheet illumination to eliminate out-of-focus background fluorescence for high-precision 3D single particle tracking. To demonstrate the capability of the method, we obtain the single fluorescent bead image with light-sheet illumination, with three-dimensional localization accuracy better than that of epi-illumination. We also show that the single fluorescent beads in agarose solution can be tracked, which demonstrates the possibility of our method for the study of dynamic processes in complex biological specimens.

Consequently, this will reduce the final resolution of the reconstructed image and cause image degradation. Therefore, it is vital to control the system drift to a minimum level as much as possible. In recent years, the anti-drift ways emerged in endlessly. In this paper we made a systematic study aiming at the method in which optical measurement and negative feedback control are used. The basic principle and its implementation of the system are analyzed, and possible error is also evaluated. Finally, the precision of the system is tested experimentally. With this device, axial drift can be detected and corrected automatically in time, and the axial anti-drift accuracy as high as 9.93 nm can be achieved, which is one order higher than that of the existing commercial microscopies.",

Meanwhile, the polarization response of the second-harmonic generation (SHG) response was investigated. The as-synthesized nanowires clearly exhibited a SHG response, which means that the nanowires were an efficient nanoscale second-harmonic light source.

"abstract": "The potassium niobate were prepared with niobium pentoxide and potassium hydroxide as source materials by hydrothermal synthesis method. The product was characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR). We also studied the effect of the concentration of potassium hydroxide solution and hydrothermal temperature on the component and morphology. The pure KNbO3 crystal could be prepared when it was synthesized at 220 oC and the concentration of potassium hydroxide solution was 10 mol/L. The as-synthesized crystal shows sheet shape with the size of 0.5-1.5 μm. When the concentration of potassium hydroxide solution was kept at 10 mol/L and the temperature was decreased to 180 oC, the product was still pure KNbO3 crystal with sheet shape and the size became 0.5-1 μm and some crystals also showed long and narrow morphology. The pure KNbO3 powder could be obtained at 180 oC when the concentration of potassium hydroxide solution was 6 mol/L, and the size of crystal was 0.4-1 μm. Some KNbO3 assemble the club-shaped crystal with the length of 10 μm. FTIR results indicate that the crystal showed Nb=O and Nb-O-Nb vibration peak. The reactive temperatures have no influence on the positions of the Nb=O and Nb-O-Nb peaks.",

"title": "A Review of Atmosphere–Ocean Forcings Outside the Tropical Pacific on the El Niño–Southern Oscillation Occurrence",
"abstract": "The El Nino–Southern Oscillation (ENSO) is the strongest interannual air–sea coupled variability mode in the tropics, and substantially impacts the global weather and climate. Hence, it is important to improve our understanding of the ENSO variability. Besides the well-known air–sea interaction process over the tropical Pacific, recent studies indicated that atmospheric and oceanic forcings outside the tropical Pacific also play important roles in impacting and modulating the ENSO occurrence. This paper reviews the impacts of the atmosphere–ocean variability outside the tropical Pacific on the ENSO variability, as well as their associated physical processes. The review begins with the contribution of the atmosphere–ocean forcings over the extratropical North Pacific, Atlantic, and Indian Ocean on the ENSO occurrence. Then, an overview of the extratropical atmospheric forcings over the Northern Hemisphere (including the Arctic Oscillation and the Asian monsoon systems) and the Southern Hemisphere (including the Antarctic Oscillation and the Pacific–South American teleconnection), on the ENSO occurrence, is presented. It is shown that the westerly (easterly) wind anomaly over the tropical western Pacific is essential for the occurrence of an El Nino (a La Nina) event. The wind anomalies over the tropical western Pacific also play a key role in relaying the impacts of the atmosphere–ocean forcings outside the tropical Pacific on the ENSO variability. Finally, some relevant questions, that remain to be explored, are discussed.",

"abstract": "This study examines the influence of boreal spring Arctic Oscillation (AO) on the subsequent winter El Niño-Southern Oscillation (ENSO) using 15 climate model outputs from the Coupled Model Intercomparison Project Phase 5 (CMIP5). Results show that, out of the 15 CMIP5 models, CCSM4 and CNRM-CM5 can well reproduce the significant AO–ENSO connection. These two models capture the observed spring AO related anomalous cyclone (anticyclone) over the subtropical western-central North Pacific, and westerly (easterly) winds over the tropical western-central Pacific. In contrast, the spring AO-related anomalous circulation over the subtropical North Pacific is insignificant in the other 13 models, and the simulations in these models cannot capture the significant influence of the spring AO on ENSO. Further analyses indicate that the performance of the CMIP5 simulations in reproducing the AO–ENSO connection is related to the ability in simulating the spring North Pacific synoptic eddy intensity and the spring AO’s Pacific component. Strong synoptic-scale eddy intensity results in a strong synoptic eddy feedback on the mean flow, leading to strong cyclonic circulation anomalies over the subtropical North Pacific, which contributes to a significant AO–ENSO connection. In addition, a strong spring AO’s Pacific component and associated easterly wind anomalies to its south may provide more favorable conditions for the development of spring AO-related cyclonic circulation anomalies over the subtropical North Pacific.",

"abstract": "The strong 2015–2016 El Nino was initiated by several strong westerly wind bursts over the equatorial western Pacific in March and May 2015. These westerly wind bursts trigger eastward propagating warm Kelvin waves and lead to large sea surface temperature (SST) warming in the equatorial eastern Pacific. The first burst of westerly winds in early March was mainly induced by the Arctic Oscillation (AO) event. These westerly wind anomalies were enhanced subsequently due to the Madden-Julian Oscillation activity and northerly cold surges from East Asia-western Pacific in mid-March. Another westerly wind burst in May, induced by anomalous southerly winds from the Australian continent, further increased the SST anomaly in the equatorial eastern Pacific. This study provides an evidence of the AO influence on this strong El Nino-Southern Oscillation (ENSO) event and demonstrates the complexity in the genesis of westerly wind bursts during the El Nino outbreak, which may help improve the prediction of ENSO.",

"abstract": "Previous studies suggested that there are large discrepancies in the intensity trend of the zonally averaged Hadley circulation (ZAHC) among different reanalyses. As the land, ocean, and topography are not evenly distributed, the ZAHC may mask the regional variability. Changes in the regional HC have important implications for regional climate change. Here, we detect the long-term trend of the boreal spring regional Hadley circulation intensity over the western Pacific (WPHC) since 1979 in both hemispheres using six reanalysis datasets. Unlike the ZAHC, we find that the trend of the spring WPHC intensity is consistent among various reanalysis datasets. All reanalyses show pronounced strengthening trends for the WPHC in both the Northern and Southern Hemisphere, which may be partly attributable to the robust warming trends of sea surface temperature in the tropical western Pacific. The result could improve our understanding of Hadley circulation variability at the regional scale and has implications for regional climate changes.",

"abstract": "Previous studies suggested that the springtime Arctic Oscillation (AO) influences the El Niño-Southern Oscillation (ENSO) outbreak in the following winter. Using the HadISST, HadSLP2r, ERSSTv3b and NCEP-NCAR reanalysis data for the period 1948–2012, this analysis further reveals that the AO–ENSO relationship experienced a pronounced interdecadal shift. The spring AO influence on the subsequent ENSO is weak before 1970; while the influence becomes strong and statistically significant in the 1970s and 1980s. We then compare the spring AO associated circulation, SST and precipitation anomalies between the PRE (1949–1968) and POST (1970–1989) epochs to explore this interdecadal change of the AO–ENSO relationship. The spring AO-related anomalies of atmospheric circulation over the North Pacific mid-latitudes, cyclonic circulation over the subtropical western-central Pacific, and westerly winds in the tropical western-central Pacific are found to be stronger in the POST epoch than in the PRE epoch. The intensity of spring Pacific synoptic-scale eddy activity is seen to experience a significant interdecadal change around the early-1970s from a weak regime to a strong regime. Thus the strength of synoptic-scale eddy feedback to the low frequency flow becomes stronger after 1970. In the POST epoch, the strong synoptic-scale eddy feedback provides a favorable condition for the formulation of the spring AO-related cyclonic circulation and westerly wind anomalies over the western North Pacific. The tropical SST, precipitation and atmospheric circulation anomalies sustain and develop from spring to winter through the positive Bjerknes feedback, leading to an El Niño-like warming in the tropical central-eastern Pacific in the following winter.",

"title": "Recent weakening of the linkage between the spring Arctic Oscillation and the following winter El Niño-Southern Oscillation",
"abstract": "Previous studies indicated that the spring Arctic Oscillation (AO) is an important extratropical forcing of the occurrence of El Niño-Southern Oscillation (ENSO) in the following winter. This study reveals an interdecadal weakening in the spring AO-winter ENSO connection around the early-1990s and investigates the reason of this change. Before the early-1990s, in association with the positive phase of the spring AO, an anomalous anticyclone appears over the mid-latitude North Pacific, accompanied by an anomalous cyclone over the subtropical North Pacific that is supported by the wave-mean flow interaction. Correspondingly, the sea surface temperature (SST) warming and its associated positive precipitation anomalies develop over the subtropical North Pacific, which play a crucial role in forming and maintaining the westerly wind anomalies over the tropical western Pacific (TWP) from spring to the following summer. The TWP westerly wind anomalies would induce the El Niño event in the following winter. After the early-1990s, by contrast, the Pacific component of the circulation anomalies related to the spring AO is weak and shifts northward. This is followed by weak anomalies of SST and precipitation over the subtropical North Pacific, as well as weak TWP westerly wind anomalies from spring to the following summer. Hence, the spring AO-winter ENSO connection is weak after the early-1990s. The change of the spring AO associated circulation anomalies over the North Pacific around the early-1990s tends to be related to the interdecadal change in the intensity of the Aleutian Low.",

"title": "Interannual variations of the rainy season withdrawal of the monsoon transitional zone in China",
"abstract": "The monsoon transitional zone (MTZ) is the interactional belt between humid and arid regions. This study examines the interannual variation of the MTZ rainy season withdrawal over China. A withdrawal index is firstly defined according to pentad mean precipitation data. The index shows pronounced interannual variations, with a significant dominant period around 2–4 years. When the withdrawal of the MTZ rainy season is later than normal, pronounced precipitation increase appears over the MTZ in August. Meanwhile, a significant anticyclonic anomaly appears over the tropical western North Pacific (WNP) and a marked atmospheric wave train is seen originating from the North Atlantic and flowing across Eurasia to East Asia. Both the anomalous anticyclone over the WNP and the negative geopotential height anomalies related to the Eurasian wave train around the MTZ contribute to the precipitation increase over the MTZ in August, and lead to the late withdrawal of the MTZ rainy season in China. It is showed that preceding winter El Niño-like events have a contribution to the generation of anticyclonic anomalies over the WNP. In addition, the northern tropical Atlantic (NTA) sea surface temperature (SST) warming, which is independent of the preceding winter El Niño, is found to play a crucial role in the formation of the WNP anticyclone and the Eurasian atmospheric wave train. The importance of the NTA SST anomalies on the MTZ rainy season withdrawal is also confirmed by a set of atmospheric general circulation model experiments.",

"abstract": "Abstract Steel slag accumulates heavily in China and has caused significant environmental burdens. In this study, secondary steel slag (SSS) was used a potential material in subgrade treatment. This study first blended SSS of different contents with lime soil and inspected the performances of the mixes in terms of compactability, strength and expansion ratio. The optimum treatment effect was obtained at a proportion of 50% SSS, 45% soil and 5% lime. Scanning electron microscopy test was conducted to reveal the strength development of SSS lime soil. The components of SSS were then supplemented by lime and metakaolin referring to the oxide compositions and proportions of the Portland cement. The unconfined compressive strength (UCS) of the reconstituted SSS increased from 0.73 MPa (plain SSS) to 4.09 MPa at 28d. Three agents, NaOH, NaCl and Na 2 SO 4 , were selected to further improve the activity of the reconstituted SSS. At the content of 5%, the UCSs of the specimens activated by NaCl and Na 2 SO 4 increased to 8.02 MPa and 10.88 MPa at 28d, respectively. The reconstitution and activation of SSS is an effective way to improve the performance in subgrade treatment.",

"abstract": "In the modeling of life cycle assessment (LCA) of pavement, the usage module is un-avoidable to reach comprehensive conclusions but far from perfect till date. Typically, the usage module consists of rolling resistance, albedo, lighting requirement, carbonation (for cement concrete pavement), leachate, and others. None of the aforementioned components is well studied among the pavement community. This research makes contribution to better modeling of the albedo effect of pavements, a traditionally ignored aspect. A time-dependent climatological model was developed to estimate the CO2 offset due to pavement albedo in the life cycle, in an either deterministic or probabilistic mode. A case study suggests that the albedo effect produces a non-negligible contribution to the life cycle inventory. Specifically, it reduces the CO2-equivalent emission for the portland cement concrete pavement by 9.2% but increases 19.1% for the hot mixture asphalt pavement.",

Cost and construction quality were concerned conventionally in the HIR practice despite the HIR construction process itself producing substantial environmental burdens. In this study, a multi-objective optimisation model was therefore developed considering the environmental impact, cost and construction quality for HIR practice. Environmental impact was quantified based on discrete-event simulation (DES), which can capture the uncertainty of construction activity and the idling state of equipment. Cost comes from material input, fuel consumption and equipment usage. Compaction degree and construction reliability were used as proxies of construction quality. The non-dominated sorting genetic algorithm II (NSGAII) was employed to solve the multi-objective optimisation problem and obtained 20 sets of Pareto optimal solutions.

A case study of three overlay systems, Portland cement concrete overlay, hot mixture asphalt overlay, and crack, seat, and overlay, is presented. The case leads to the following conclusions. It is reasonable to expect less environmental burdens from the Portland cement concrete and crack, seat, and overlay options as opposed to hot mixture asphalt while although the results have a high degree uncertainties. The material, congestion, and particularly usage modules contribute most to energy consumption and air pollutant.

"abstract": "This study carried out laboratory investigations of fatigue damage development of hot mix asphalt (HMA) by semicircular bending (SCB) test. Strength of the HMA specimen was first investigated at different loading rates, the results of which indicate an exponential relationship between strength and loading rate. The SCB fatigue test at stress-control mode was then performed at six levels of stress-strength ratio (SSR). Two fatigue life prediction models have been established accordingly based on the concepts of the nominal SSR and the authentic SSR. The latter model can better predict fatigue behaviors. As follows, another round of SCB fatigue test was continued to investigate the relationship between residual strength and fatigue damage evolution. Analysis of test results indicate that fatigue damage evolution is nonlinear and consists of two components: the accumulative damage development and last-cycle damage jump. A fatigue damage evolution model has been finally built based on the residual strength, which can capture the “sudden death” phenomenon of the fatigue damage process at stress-control mode.

However, the environmental burden of HIR process itself is remarkable but has been conventionally ignored. This study presented a discrete event simulation (DES) method to estimate and compare the environmental burdens of two HIR methods, the remixing method (A) and the repaving method (B). The simulation results indicated: (1) with the same paving mass, the emissions of A were greater than those of B by 19–21%; (2) with the same paving length, the emissions of A were less than those of B by 23–26%. Optimizations of the construction process were further conducted considering air emission, fuel consumption and construction time. Optimal truck number subject to transportation distance was recommended. And the impact of increasing truck capacity and altering truck dumping process calculated, with the former decreasing environmental burdens and the latter bringing trivial benefit. The developed DES model provides quantitative estimations of environmental burdens and allows for optimization of HIR construction process subject to field conditions.",

"abstract": "Abstract Substantial energy consumption and CO 2 emission are generated in asphalt pavement maintenance and their quantifications based on individual case are highly contingent on the input data qualities and model parameters, exhibiting high uncertainties. This study established energy consumption and CO 2 emission uncertainty assessment statistical methodology to deal with the issue. Two sources of uncertainty, the data quality one and the model parameter one, were identified. The former was captured by converting the input data to probability density function (PDF) using Beta distribution following the definitions of data quality pedigree matrix; the latter was assessed by defining uncertainty factor (UF) to determine the distribution form and parameter. Environmental data of 18 field asphalt pavement maintenance projects were collected, including hot mix asphalt (both base and SBS modified asphalts), hot in-plant recycling (15% reclaimed asphalt pavement), cold in-place recycling and cold in-plant recycling asphalt maintenance plans, covering pavement material production, transportation, mixture preparation and construction phases. The PDFs and statistical parameters (mean, standard deviation and percentiles etc.) were obtained via Monte Carlo simulation for these maintenance measures. This study further developed environmental burden comparative parameter to construct the 95% confidence intervals for the comparisons of different maintenance measures. The methodology proposed in this study captured the uncertainty of energy consumption and CO 2 emission calculation results of maintenance activity and allow researchers to evaluate the results in a statistical view.",

The test variables involved diameter, thread depth, thread width, embedment length of GFRP bar and cement strength, a total of 32 combinations. Test results indicate the optimum GFRP bar is with thread gap of 0.8-diameter, thread depth of 1 mm, and in favor of small diameter size. The GFRP reinforced specimens provide approximately 60% of bond strength benchmarked by the steel reinforced specimens but have much higher slip length. Lastly, four-point bending test was applied to five types of GFRP/steel reinforced concrete beams to investigate the mechanical responses of the beams until failure. Test results indicate at the same reinforcement ratio and geometric size, GFRP bar and steel bar have the same bearing capacities. However, the former is inferior to the latter in terms of crack control.",

"abstract": "Abstract The carbon footprint of pavement in the life cycle is regularly calculated by aggregating the inventory of greenhouse gases (GHGs) at different timings. Comparisons by the nominal values, therefore, ignore the temporal information and may lead to biased estimation of the environmental impact. This study proposed a time-dependent methodology to dynamically assess the global warming potentials (GWPs) incorporating two time parameters, time of evaluation (TE) and time horizon (TH). The former defines the time period of life cycle assessment (LCA) and the latter decides when the GWP is evaluated. Two case studies were conducted. The first case study indicated for design lives ( viz. TE) of 20 y and 40 y, the GWPs are significantly overestimated by 59.7% and 33.0%; the second case study indicated that 66 y is the threshold value for TH that brings different policy preference for two emission plans. Together with the concept of “time dominance”, a generic implementation framework was established for the methodology so that users can justify the preferences of alternatives at any THs. The developed methodology can assist decision makers in understanding the real impacts of carbon emission within and beyond pavement life cycle.",

The objective of this paper is to analyze the effect of CVs on running speed. This study compared the delay time, travel time, and running speed in the normal and the connected states, respectively, through VISSIM (a traffic simulation software developed by PTV company in German). The optimization speed model was established to simulate the decision-makings of CVs in MATLAB, considering the parameters of vehicle distance, average speed, and acceleration, etc. After the simulation, the vehicle information including speed, travel time, and delay time under the normal and the connected states were compared and evaluated, and the influence of different CV rates on the results was analyzed. In a two-lane arterial road, running speed in the connected state increase by 4 km/h, and the total travel time and delay time decrease by 5.34% and 16.76%, respectively, compared to those in the normal state. The optimal CV market penetration rate related to running speed and delay time is 60%. This simulation-based study applies user-defined lane change and lateral behavior rules, and takes different CV rates into consideration, which is more reliable and practical to estimate the impact of CV on road traffic characteristics.",

"abstract": "Abstract This study investigated the microstructure features of cold in-place recycled (CIR) asphalt mixtures by the X-ray computed tomography (CT) and digital image processing (DIP) methods. A variety of CIR asphalt mixtures were prepared considering four types of aggregate gradation and three type of compaction method. The air void distribution characteristics of CIR specimens were analyzed based on the concept of air void gradation. A two-parameter Weibull function was used to fit the air void gradation, of which the statistical parameters are sensitive to both the aggregate gradation and compaction method. The concept of thickness spectrum was then developed to characterize the thickness distribution of cement asphalt (CA) mortar. Lognormal function was observed of good fitness of thickness spectrum. Finally, the uniformity index (UI) was built to evaluate the homogeneity of CIR mixtures and found the UIs of CIR mixture decreases gradually with the gradation from fine to coarse, and among the three compaction methods, the Superpave gyratory compaction is the best in terms of homogeneity. The findings of this study provide a solid foundation in exploring the internal structure and guiding the mix design of CIR mixtures.",

"abstract": "AbstractIn performing pavement life cycle assessment (LCA), users are facing various reports of energy intensity coefficient (EIC) of pavement materials which differ considerably among data sources and therefore alter the LCA results significantly. Instead of selecting a certain EIC without or of little explanation for the current pavement LCA practices, this study proposed a methodology to build probability density function (PDF) for EIC based on available data-set and their qualities. Each data was first evaluated about the data quality indicator (DQI) through data quality pedigree matrix and converted to PDF in modified Beta distribution form. Three weighting methods, the DQI one, coefficient of variation (COV) one and analytical hierarchy process (AHP) one, were developed to assign weightings for different data. Monte Carlo simulation was run with the weighted PDF of each data as input to obtain the ultimate PDF for EIC. A case study to estimate the bitumen’s EIC with eight data samples were performed...",

"abstract": "During neurological surgery, neurosurgeons have to transform the two-dimensional (2D) sectional images into three-dimensional (3D) structures at the cognitive level. The complexity of the intracranial structures increases the difficulty and risk of neurosurgery. Mixed reality (MR) applications reduce the obstacles in the transformation from 2D images to 3D visualization of anatomical structures of central nervous system. In this study, the holographic image was established by MR using computed tomography (CT), computed tomography angiography (CTA) and magnetic resonance imaging (MRI) data of patients. The surgeon's field of vision was superimposed with the 3D model of the patient's intracranial structure displayed on the mixed reality head-mounted display (MR-HMD). The neurosurgeons practiced and evaluated the feasibility of this technique in neurosurgical cases. We developed the segmentation image masks and texture mapping including brain tissue, intracranial vessels, nerves, tumors, and their relative positions by MR technologies. The results showed that the three-dimensional imaging is in a stable state in the operating room with no significant flutter and blur. And the neurosurgeon's feedback on the comfort of the equipment and the practicality of the technology was satisfactory. In conclusion, MR technology can holographically construct a 3D digital model of patient's lesions and improve the anatomical perception of neurosurgeons during craniotomy. The feasibility of the MR-HMD application in neurosurgery is confirmed.",

"abstract": "The prediction of clinical outcome for patients with infiltrative gliomas is challenging. Although preoperative hematological markers have been proposed as predictors of survival in glioma and other cancers, systematic investigations that combine these data with other relevant clinical variables are needed to improve prognostic accuracy and patient outcomes. We investigated the prognostic value of preoperative hematological markers, alone and in combination with molecular pathology, for the survival of 592 patients with Grade II-IV diffuse gliomas. On univariate analysis, increased neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), and decreased albumin-to-globulin ratio (AGR), all predicted poor prognosis in Grade II/III gliomas. Multivariate analysis incorporating tumor status based on the presence of IDH mutations, TERT promoter mutations, and 1p/19q codeletion showed that in lower-grade gliomas, high NLR predicted poorer survival for the triple-negative, IDH mutation only, TERT mutation only, and IDH and TERT mutation groups. NLR was an independent prognostic factor in Grade IV glioma. We therefore propose a prognostic model for diffuse gliomas based on the presence of IDH and TERT promoter mutations, 1p/19q codeletion, and NLR. This model classifies lower-grade gliomas into nine subgroups that can be combined into four main risk groups based on survival projections.",

"abstract": "Inflammation and immunoreaction markers were correlated with the survival of patients in many tumors. However, there were no reports investigating the relationships between preoperative hematological markers and the prognosis of medulloblastoma (MB) patients based on the molecular subgroups (WNT, SHH, Group 3, and Group 4). A total 144 MB patients were enrolled in the study. The differences of preoperative hematological markers among molecular subgroups of MB were compared by One-way ANOVA method. Kaplan-Meier method was used to calculate the curves of progression free survival (PFS) and overall survival (OS). The comparison of survival rates in different groups were conducted by the Log-rank test. Multivariate analysis was used to evaluate independent prognostic factors. Increased preoperative NLR (neutrophil-to-lymphocyte ratio, PFS, P = 0.004, OS, P < 0.001) and PLR (platelet-to-lymphocyte ratio, PFS, P = 0.028, OS, P = 0.003) predicted poor prognosis in patients with MB, while preoperative MLR (monocyte-to-lymphocyte ratio), MPV (mean platelet volume), PDW (platelet distribution width), and AGR (albumin-to-globulin ratio) were revealed no predictive value on the prognosis of patients with MB. Furthermore, high preoperative NLR and PLR predicted unfavorable prognosis in childhood MB patients. However, preoperative NLR and PLR were not associated with the prognosis in adult MB patients. Multivariate analysis demonstrated preoperative NLR (PFS, P = 0.029, OS, P = 0.005) and PLR (PFS, P = 0.023, OS, P = 0.005) were the independent prognostic factors in MB patients. Emphatically, the levels of preoperative NLR and PLR in Group 3 MB were significantly higher than those in WNT MB. High preoperative NLR was associated with unfavorable OS in Group 3 (P = 0.032) and Group 4 (P = 0.027) tumors. Similarly, increased preoperative PLR predicted poor PFS (P = 0.012) and OS (P = 0.009) in Group 4 tumors. Preoperative NLR and PLR were the potential prognostic markers for MB patients. Preoperative NLR and PLR were significantly associated with the survival of Group 3 and Group 4 tumors.",

"abstract": "A previous study revealed that ubiquitin-like with PHD and RING finger domains 1 (UHRF1) promoted cell proliferation and was a potential biomarker in medulloblastoma (MB). In the present study, we reported that miR-378 inhibited the expression of UHRF1 to affect the proliferation of MB through competitive binding to the same region of its 3'-UTR. We found that the expression of miR-378 was significantly downregulated in MB tissues and inversely correlated with the expression of UHRF1. Western blot analysis revealed that overexpression of miR-378 led to the suppression of UHRF1. Moreover, a dual-luciferase assay demonstrated that miR-378 negatively regulated the activity of target gene UHRF1 by binding to its 3'-UTR. An in vitro assay revealed that overexpression of miR-378 suppressed MB cell proliferation and promoted cell apoptosis. Ectopic expression of UHRF1 rescued miR-378-suppressed cell proliferation and miR-378-promoted cell apoptosis. Collectively, the present study demonstrated that miR-378 could inhibit the proliferation of MB by downregulation of UHRF1 and act as a potential therapeutic target against MB.",

"title": "IDH mutations but not TERTp mutations are associated with seizures in lower-grade gliomas.",
"abstract": "Glioma is the most common malignant tumor in the central nervous system (CNS). Lower-grade gliomas (LGG) refer to Grade II and III gliomas. In LGG patients, seizure often appears as an initial symptom and play an important role in clinical performance and quality of life of the patients. To date, the relationship between the onset of seizures and the molecular pathology in gliomas is still poorly investigated. In this study, we investigate the potential relationship between isocitrate dehydrogenase (IDH)/telomerase reverse transcriptase promoter (TERTp) mutations and preoperative seizures in patients with LGG. 289 adult LGG patients were enrolled in this study. Data of clinical characteristics and molecular pathology were acquired. Sanger sequencing was used to detect IDH/TERTp mutations. Chi-square test was performed to determine if the IDH/TERTp mutations were associated with seizures and seizure types. In 289 LGG patients, preoperative seizures accounted for 25.3% (73/289), IDH mutations accounted for 34.3%(99/289), and TERTp mutations accounted for 44.3% (128/289). The correlation analysis demonstrated that IDH mutation is a significant factor influencing the occurrence of tumor-related epilepsy (P <.001, chi-square test). On the other hand, the statistical analysis revealed no significant correlation between TERTp mutations and seizure in LGG patients (P = .102, chi-square test). The tumor-related epilepsy rates vary among different subgroups according to IDH/TERTp mutations. However, there is no definite correlation between the IDH (P = 1.000, chi-square test)/TERTp (P = .613, chi-square test) mutations and the types of epileptic seizure. IDH mutations are more common in preoperative LGG patients with epileptic symptoms, suggesting that this mutation is positively correlated with seizures. However, there was no significant correlation between TERTp mutations and seizures. Different molecular pathologic types based on IDH/TERTp have different incidences of tumor-associated epilepsy in LGGs.",

The results show that PA6/TiO2 complex belonged to the melt-shear-thinning fluid; their apparent viscosity became lower as the shear rate increased; their viscous flow activation energy was higher than that of pure PA6 fluid. Crystallinity and thermal stability were made no difference by TiO2 when contents of TiO2 particles were less; they were significantly improved, with a high level of contents of TiO2 particles.",

In this paper, the influence of drawing pressure on the properties of spun-bonded PET/PA6 hollow pie wedge bicomponent filaments was studied, and their performance was characterized by differential scanning calorimetry, X-ray diffraction, scanning electron microscopy, Beion F6 fiber fineness tester, and single fiber strength tester. The hollow pie wedge bicomponent fiber had a distinct interface between the two polymers due to poor compatibility. With increasing of drawing pressure, diameter of the fibers reduced regularly. When the drawing pressure increased, both the degree of crystallinity and orientation of bicomponent fibers enhanced, and the melting point of polyester component increased as well. Furthermore, with increasing of drawing pressure, the breaking strength of the fibers increased, but the breaking elongation and linear density decreased.",

Edge effects of Ni-polycide formation, enhanced by a recessed spacer, results in gate Rs roll-off with poly line width. Ultra low /spl sim/2 /spl Omega///spl square/ gate Rs is achieved for 50 nm line width with low junction leakage. Source/drain series resistance is significantly reduced and, consequently, drive current is improved with NiSi. Ring oscillator speed measurements showed significant improvement in gate delay with NiSi, especially for the ring oscillators made with large gate width devices.",

"title": "Altered carbon assimilation and cellulose accessibility to maximize bioethanol yield under low-cost biomass processing in corn brittle stalk",
"abstract": "Although cellulosic ethanol has been regarded as an ideal additive for transportation fuels, its low accessibility from recalcitrant lignocellulose renders the bioethanol process unacceptably expensive for commercial production. Here, this study collected the brittle stalk of a corn mutant, bk1, that showed similar biomass and seed yields to its wild type (elite cultivar). We then detected significantly reduced cellulose content and degree of polymerization of beta-1,4-glucans, leading to a 74% increase in directly-fermentable hexoses accumulation in the brittle stalk by reducing sucrose production and altering carbon assimilation. Notably, under two green-like pretreatments (20 min liquid hot water, 15% CaO at 50 degrees C), the brittle stalk exhibited remarkably improved cellulose accessibility for almost complete biomass saccharification. This resulted in achieving the highest bioethanol yield of 19.3% (% dry matter) to date, outperforming previous efforts that relied on harsh corn stalk pretreatments. Furthermore, even without any pretreatment, we evaluated that the brittle stalk could deliver a bioethanol yield of 20.3% if the total xylose and hexoses from the brittle stalk were combined for yeast co-fermentation. This study has thus provided a prospective new model for the green-like bioethanol industry that integrates engineered bioenergy crops and yeast strains with cost-effective biomass processing.",

"abstract": "With increasing demands on the high-performance and environmental-friendly melt-blown nonwovens (MBs) for separation and filtration, herein, we reported a poly(lactic acid)/polyamide 11 (PLA/PA11) 100% bio-based MBs in situ compatibilized by dual-monomer glycidyl methacrylate-styrene melt-grafted poly(lactic acid) (PLA-g-(St-co-GMA)). The morphology, crystallization, thermal and rheological behaviors of reactive extruded PLA/PA11/PLA-g-(St-co-GMA) melt blends were investigated, and the structure and filtration performance of corresponding MBs were fully characterized. The results indicated that the interface between PLA and PA11 were effectively improved due to the compatibilizer of PLA-g-(St-co-GMA). PA11 promoted the cold crystallization and enhanced the thermal stability of PLA matrix. The reactive blends displayed a higher viscosity with unchanged rheological behaviors compared with PLA. In comparison with PLA MBs, the average fiber diameter and pore size of PLA/PA11/PLA-g-(St-co-GMA) MBs were slightly increased, whereas the strength and toughness were significantly improved. All the PLA/PA11/PLA-g-(St-co-GMA) MBs presented high air permeability and low filtration resistance. High filtration efficiency (>99.8%) could also be obtained especially for the target particles with diameters larger than 2.5 mu m.",

"abstract": "In this work, the blend films of poly(lactic acid) (PLA) and poly(e-caprolactone) (PCL) were prepared by the solvent casting method. The influence of PCL content and compatibilizer on the structure, tensile and barrier properties was studied. The results indicated that PCL showed good dispersion in PLA matrix as tributyl citrate (TBC) was added as a compatibilizer. PCL showed a promotion effect on the crystallinity of PLA/PCL films. The compatibility of PLA and PCL was improved by TBC. The tensile modulus and the elongation at break of PLA/PCL films increased to various extents due to the input of PCL and TBC compared to pure PLA film. The improvement of oxygen and water vapor barrier properties of the blend films were provided and depended on the content of PCL and the appearance of TBC. The transparency of the blend films decreased with the increase of the PCL content.",

"abstract": "To develop degradable and magnetic PLA-based melt-blown (MB) nonwoven materials for air filtration applications, poly (lactic acid) (PLA)/magnetic Fe3O4 (PLA/Fe3O4) MB nonwovens were obtained by melt blowing using the PLA/Fe3O4 composites with different components prepared by melt-mixing as the masterbatch. The crystallization and melting behavior of the composites were examined with differential scanning calorimetry (DSC). Although the results showed that the Fe3O4 particles obviously hindered the cold crystallization process of PLA and the relative crystallinity degree of the composites decreased due to the addition of Fe3O4; there was no overall change in the crystal structure of PLA according to the wide-angle X-ray diffraction (XRD). Thermogravimetric analysis (TGA) and dynamic rheological measurements demonstrated that the introduction of Fe3O4 reduced the thermal stability of PLA. The effect of Fe3O4 particles on the morphology of the PLA/Fe3O4 composites and MB nonwovens was characterized by scanning electron microscopy (SEM). It revealed that the Fe3O4 particles were dispersed in a PLA mixture with the \"sea-island\" structure, and the addition of Fe3O4 particles also made the fiber surface rough and the nonwoven web turned fluffy to some extent. The magnetic properties and filtration performance of the MB nonwovens were also investigated in detail.",

Firstly blends were prepared with variant LMPP contents, and their properties were characterised using SEM, DSC, XRD, and DMA. Later the mechanical properties of iPP/LMPP blend fibres were investigated. SEM results showed that the iPP/LMPP blends produced smoother surfaces when the LMPP content was increased, as well as the miscibility. All the T-g values with different LMPP percentages were in-between pure iPP and LMPP. The XRD results indicated the LMPP percentage decreased along with the degree of crystallinity of the iPP/LMPP blends (5% to 15%), which increased and then decreased as compared to pure iPP. The elongation at break increased when the LMPP content increased, with the maximum elongation at break of the LMPP 25% blend reaching 12.95%, which showed great stretch-ability, whereas the elastic modulus of iPP/LMPP blends decreased.",

"abstract": "To develop fully biodegradable and reinforced poly(lactic acid) (PLA) melt-blown nonwovens (MBs) for separation and filtration, PLA/aminated halloysite nanotubes (PLA/A-HNTs) MBs were prepared using PLA/A-HNTs master-batches, compatibilized by dual-monomer glycidyl methacrylate-styrene (St-co-GMA) melt-grafted PLA (PLA-g-(St-co-GMA)). The morphology, crystallization, pore size distribution, filtration performance, and mechanical properties of PLA/PLA-g-(St-co-GMA)/A-HNTs MBs were characterized. The results indicated that PLA/PLA-g-(St-co-GMA)/A-HNT MBs could be successfully manufactured, with well dispersed A-HNTs in PLA MB fibers due to improved compatibility by PLA-g-(St-co-GMA). Incorporation of A-HNTs and PLA-g-(St-co-GMA) slightly increased the average diameter and pore size of PLA MBs. A-HNTs increased the crystallinity degree of PLA MBs, while the crystal forms remained unchanged. In comparison with PLA MBs, the tensile strengths of PLA/PLA-g-(St-co-GMA)/A-HNTs MBs were enhanced but the elongation decreased. PLA/PLA-g-(St-co-GMA)/A-HNT MBs could obtain higher filtration efficiency than neat PLA MBs.",

Their structure and properties were investigated by differential scanning calorimetry, thermal mechanical analyzer (DMA), X-ray diffraction, polarized optical microscope, field emission scanning electron microscope, and a universal testing machine, respectively. The results showed that the addition of PDLA decreased the glass transition temperature of PLLA. The PLLA/PDLA blends with the 0.3 % PDLA had the lowest the melting temperature and the degree of crystallization. The growth rate and size of the spherulites of the blends increased with the increase of the PDLA content. PLA stereocomplex could be achieved in the PLLA/PDLA blends. PDLA phase was dispersed uniformly in PLLA matrix in the formation of small circular particles. An increase of the PDLA content resulted in the improvement of the fracture toughness of the blends. When the PDLA content was 0.3 %, the blends achieved the highest elongation at break and toughness. Moreover, PDLA had a positive effect on the enhancement of the toughness of PLLA/PDLA melt-blown nonwovens.",

This work explores the possibility of this two-dimensional nanomaterial as flame retardant. The layered MEL-PA with the loading of 1, 2 and 3 wt% are incorporated into polypropylene (PP) matrix. MEL-PA is dispersed well in the PP matrix. Thermal stability and flame retardant performance of PP/MEL-PA composites are investigated. Compared with neat PP, the addition of 2 wt% MEL-PA decreases the peak heat release rate from 756 to 608 kW/m2. Char yield of PP is improved by MEL-PA, and the chemical structure and graphitization degree of residual char are studied to reveal flame retardant mechanism.",

"abstract": "A novel and submicro-scale aluminum branched oligo(phenylphosphonate) (AHPP) has been successfully synthesized and embedded into a polymeric substrate to improve the fire safety of epoxy resin (EP). The chemical structures of intermediates and target products were characterized using the nuclear magnetic resonance spectroscopy, X-ray diffraction and Fourier transform infrared analysis. Morphology analysis confirmed that all of the as-synthesized AHPP submicro-particles are mutually well-separated. Combustion results demonstrated that the limiting oxygen index value is increased to 30.5% from 23.5% while the PHRR and THR are decreased by ca. 68.1% and 41.2%, respectively for the EP/AHPP-7.5 composite compared to the corresponding values for pure EP. In addition, the binary blends display the satisfying smoke toxicity suppression performance during combustion. The total smoke production and the total CO yield for EP/AHPP-7.5 are dramatically reduced by 62.0% and 32.3%, respectively, which may mainly be ascribed to the catalytic carbonization performance of the polymers and formation of AlO layers on the surface of the char residues. As a result, the findings in this study enabled the submicro-scale phosphorus-containing flame retardant to be a potential candidate as an efficient additive for reducing smoke toxicity of polymer composites.",

The chemical structures, composition, and morphology of the graphene nanohybrid are characterized. Alumina nanoflake-coated graphene nanohybrid is incorporated into polypropylene (PP) matrix by master batch-based melt mixing method. The effects of alumina-graphene nanohybrid on the thermal stability and combustion behavior of PP are investigated. More char residue is left for PP composite containing alumina-graphene nanohybrid. Peak heat release rate of pure PP is greatly decreased by this nanohybrid, corresponding to 30.6% reduction. Fire safety of PP is considerably enhanced. Flame retardant mechanisms are concluded based on the combustion results and char analysis. The barrier effect of graphene and catalytic charring actions of gamma-Al2O3 nanoflakes make the contribution to the enhanced flame retardant properties.",

"abstract": "The extemporaneous combustion of coal remains a major threat to safety in coal mines because such fire accidents result in casualties and significant property loss, as well as serious environmental pollution. This work proposed the fabrication of flame-retardant rigid polyurethane foam (RPUF) containing expandable graphite as char expander/sealant with melamine phosphosphate and 2-carboxyethyl (phenyl)phosphinic acid as char inducer and radical trapping agents. The as-prepared RPUF successfully inhibited coal combustion by forming thermally stable high graphitic content expandable intumescent char sealing over the coal. The RPUF achieved UL-94 V-0 rating in addition to significant reductions in peak heat release, total heat release, and CO and CO yields. The external and the internal residual char structure was studied by X-ray photoelectron spectra, Raman spectroscopy, and real-time Fourier transform infrared spectra techniques, and a flame-retardant mode of action has been proposed. This work provides important insight into a facile fabrication of highly efficient and economical flame-retardant RPUF to inhibit the spontaneous combustion of coal.",

"abstract": "Polyimide (PI) aerogels have attracted great attention owing to their low density and excellent thermal stability. However, hydrophobic surface modification is required for PI aerogels to improve their ability in oil/water separation applications due to their amphiphilic characteristic. 2D MXenes (transition metal carbides/nitrides) can be utilized as nanofillers to enhance the properties of polymers because of their unique layered structure and versatile interface chemistry. Herein, the robust, lightweight and hydrophobic polyimide/MXene 3D architectures were fabricated via freeze-drying of polyamide acid/MXene suspensions and thermal imidization. Polyamide acid (PAA) was synthesized using N-N-dimethylacetamide (DMAC) and 4,4'-oxydianiline (ODA). MXene (Ti3C2Tx) dispersion was obtained via the etching of Ti3AlC2 and ultrasonic exfoliation. Taking advantage of the strong interaction between PI chains and MXene nanosheets, the interconnected, highly porous and hydrophobic PI/MXene aerogels with low density were fabricated, resulting in the improved compressive performance, remarkable oil absorption capacity and efficient separation of oil and water. For the PI/MXene-3 aerogel (weight ratio: 5.2/1) without any surface modification, the water contact angle was 119° with a density of 23 mg/cm3. This aerogel can completely recover to its original height after 50 compression-release cycles, exhibiting super elasticity and exceptional fatigue resistant ability. It also showed high absorption capacities to various organic liquids ranging from approximately 18 to 58 times of their own weight. This hybrid aerogel can rapidly separate the chloroform, soybean oil and liquid paraffin from the water-oil system. The thermally stable hybrid aerogel also exhibited excellent fire safety properties and outstanding reusability under extreme environment.",

"title": "Preparation and performances of coated and aluminous entry boards with water-soluble resins for PCB drilling",
"abstract": "PurposeThis paper aims to provide a new drilling entry board for printed circuit board (PCB) process, superior in heat dissipation, lubrication, water solubility and hole location accuracy, achieving an excellent drilling process.Design/methodology/approachUsing a mixture of polyethylene glycol (PEG) and water-soluble adhesives as hydrosoluble, endothermic and lubricant resins and aluminum foils as baseplates, a series of coated and aluminous entry boards (CABs) for PCB drilling was successfully prepared. The surface appearance of the entry boards was observed clearly by scanning electron microscopy (SEM). The endothermic and lubricant effects of the resins applied on the CABs was characterized by differential scanning calorimetry (DSC) and their water solubility was tested in the normal-temperature water (25°C). Moreover, the CABs’ good drilling properties were tested when they were used for PCB drilling.FindingsThe SEM analysis showed that the surfaces of the resin layers coated on the CABs whose coating thicknesses were less than 80 μm were smoother and flatter, which could improve hole location accuracy and reduce drill breakage ratio. By virtue of DSC, the endothermic and lubricant effects of the CABs were proven. The fusion of PEG in the resin layers could absorb the heat produced by drilling, restrain the temperature of the drill bit and hole rising and lubricate the drill bit efficiently when a hole was being drilled, which could achieve high-quality holes with good production efficiency. The water-soluble test showed that the prepared CABs had excellent water solubility at normal temperature, enabling the resin left on the hole walls and in the flute of the drill bit to be washed away easily and thereby improving the drilling efficiency and quality. The drilling tests showed that the increase in the thickness of the CABs’ coating could improve the hole location accuracy and alleviate the bit wear. In addition, the suitable coating thickness could ensure the firm adhering of the resin coating the aluminum foil, effectively avoid drill intertwist and prevent the resin debris from blocking the drilled holes on the surface of the entry board, which could hinder chip removal, resulting in poor hole wall quality and drill breakage.Originality/valueThis paper has a remarkably high industrial practicality in the PCB manufacture process.",

Firstly, we use the Banach fixed point theorem to establish the existence of weighted pseudo-almost periodic solutions for this class of QVCNNs. Then, under the condition that the drive system has a unique weighted pseudo-almost periodic solution, by designing a state-feedback controller and constructing suitable Lyapunov functions, we see that the drive–response structure of delayed QVCNNs with weighted pseudo-almost periodic coefficients achieve global exponential synchronization.

By analyzing the corresponding characteristic equation, the local stability of a positive equilibrium is considered. Moreover, we show that Hopf bifurcations occur when time delay crosses some critical values. By deriving the equation describing the flow on the center manifold, we give the formula for determining the direction of the Hopf bifurcation and the stability of bifurcating periodic solutions. In addition, we also try on the global existence of periodic solutions by using the global Hopf bifurcation result of Wu [J. Wu, Symmetric functional differential equations and neural networks with memory, Trans. Amer. Math. Soc. 350 (1998) 4799-4838.] for functional differential equations. Numerical simulations are carried out to illustrate the theoretical results and they show that the time delays in the system under consideration can destroy the stability of the system.",

"title": "Understanding Persuasion Cascades in Online Product Rating Systems",
"abstract": "Online product rating systems have become an indispensable component for numerous web services such as Amazon, eBay, Google play store and TripAdvisor. One functionality of such systems is to uncover the product quality via product ratings (or reviews) contributed by consumers. However, a well-known psychological phenomenon called \"message-based persuasion\" lead to \"biased\" product ratings in a cascading manner (we call this the persuasion cascade). This paper investigates: (1) How does the persuasion cascade influence the product quality estimation accuracy? (2) Given a real-world product rating dataset, how to infer the persuasion cascade and analyze it to draw practical insights? We first develop a mathematical model to capture key factors of a persuasion cascade. We formulate a high-order Markov chain to characterize the opinion dynamics of a persuasion cascade and prove the convergence of opinions. We further bound the product quality estimation error for a class of rating aggregation rules including the averaging scoring rule, via the matrix perturbation theory and the Chernoff bound. We also design a maximum likelihood algorithm to infer parameters of the persuasion cascade. We conduct experiments on the data from Amazon and TripAdvisor, and show that persuasion cascades notably exist, but the average scoring rule has a small product quality estimation error under practical scenarios.",

"title": "DCS: Diagonal Coding Scheme for Enhancing the Endurance of SSD-Based RAID Arrays.",
"abstract": "To guarantee high reliability, solid-state drive (SSD)-based storage systems require data redundancy schemes, e.g., redundant array of independent disks (RAID) schemes. Traditional RAID-5, RAID-6, and Reed-Solomon codes can tolerate one, two, and an arbitrary number of device failures, respectively. However, some SSDs under those redundant configurations may age much faster than others because of the high skewness and locality of workloads. The uneven aging rates may make some SSDs wear out very quickly and decrease the endurance of SSD-based RAID arrays. To address this problem, we first come up with a diagonal coding scheme (DCS) by distributing the updating dependencies evenly among devices to improve the system-level wear-leveling. DCS can efficiently improve the array endurance if requests are aligned with the stripe size, i.e., when data symbols in the same stripe receive the same number of writes, while the number could be different for different stripes. To relax the above assumption, we further propose an enhanced scheme, DCS+. With a buffer design, DCS+ can improve the wear-leveling among devices under general access patterns via triggering different responses to different kinds of requests. We conduct extensive trace-driven evaluations based on real-world workloads, and results show that our design efficiently enhances the endurance of SSD-based RAID arrays.",

"title": "ISM- An Intra-Stripe Data Migration Approach for RAID-5 Scaling.",
"abstract": "Scaling is often carried out in modern RAID systems to meet the ever increasing demand of storage capacity and I/O performance. However, the scaling process of RAID-5 system is not trivial, due to its specific data/parity layout. Previous approaches of RAID-5 scaling require either migrating almost all data blocks in the system, or recalculating all or some of the parity blocks during scaling. This paper proposes a new RAID-5 scaling approach called ISM (Intra-Stripe Migration). With ISM, data migrations only happen within stripes, which means that the coding relationship among blocks remains the same. Therefore, the parity blocks do not need to be recalculated after data migration, which greatly reduces the I/O and computational costs. The properties of ISM approach can be summarized as follows: (1) it requires the minimum amount of data blocks to be migrated, (2) it supports data migration without recalculating parity blocks, and (3) it supports multiple successive scaling operations while keeping the above properties. The simulation results on DiskSim show that: (1) ISM reduces the scaling time from 47.91% to 87.01% and from 88.94% to 96.58% compared with GSR and ALV respectively in offline scaling, (2) under two real-world I/O traces, ISM also outperforms GSR by 64.15% to 87.30%, and ALV by 92.38% to 95.98% in scaling time, and (3) ISM maintains almost the same performance of data access with ALV and GSR after scaling.",

"abstract": "Pollution attack is known to have a disastrous effect on existing P2P infrastructures: it can reduce the number of legitimate P2P users by as much as 85%, and it generates abundant bogus data which may deplete the communication bandwidth. We propose a distributed defense and detection mechanism to resolve pollution attacks. The mechanism is composed of a set of ''randomized'' and ''fully distributed'' algorithms that can be executed by any legitimate peer. We present the analytical framework to quantify (a) the probability of false negative, (b) the probability of false positive, and (c) the distribution of time needed for detection. In our detection algorithm and analysis, we consider the case of (1) single attacker within the neighborhood, (2) multiple attackers within the neighborhood. Furthermore, we show how to ''optimize'' the system parameters so as to quickly discover and eliminate malicious peers from the system.",

"title": "HP-Mapper - A High Performance Storage Driver for Docker Containers.",
"abstract": "Docker containers are widely deployed to provide lightweight virtualization, and they have many desirable features such as ease of deployment and near bare-metal performance. However, both the performance and cache efficiency of containers are still limited by their storage drivers due to the coarse-grained copy-on-write operations, and the large amount of redundancy in both I/O requests and page cache. To improve I/O performance and cache efficiency of containers, we develop HP-Mapper, a high performance storage driver for Docker containers. HP-Mapper provides a two-level mapping strategy to support fine-grained copy-on-write with low overhead, and an efficient interception method to reduce redundant I/Os. Furthermore, it uses a novel cache management mechanism to reduce duplicate cached data. Experiment results with our prototype system show that HP-Mapper significantly reduces copy-on-write latency due to its finer-grained copy-on-write scheme. Moreover, HP-Mapper can also reduce 65.4% cache usage on average due to elimination of duplicated data. As a result, HP-Mapper improves the throughput of real-world workloads by up to 39.4%, and improves the startup speed of containers by 2.0x.\n\n",

"title": "LCR: Load-Aware Cache Replacement Algorithm for Flash-Based SSDs.",
"abstract": "Flash-based SSDs are usually equipped with an onboard cache to further improve system performance by smoothing the gap between the upper-level applications and lower-level flash chips. Since modern SSDs are usually composed of multiple flash chips, and the load of flash chips are significantly different, it is very meaningful to be aware of the chip load condition when designing a cache replacement algorithm. Nevertheless, existing cache replacement algorithms only consider to reduce the cache miss ratio so as to reduce the I/O requests to the underlying flash memory as much as possible, none of them considers the load condition of flash chips. In this paper, we propose a Load- aware Cache Replacement algorithm, called LCR, to improve the performance of flash-based SSDs. The basic idea is to give a higher priority to cache the blocks on overloaded flash chips. We evaluate the performance of our scheme by using a trace- driven simulator with multiple real-world workloads, and results show that compared with the most common algorithm LRU and the state-of-the-art algorithm GCaR, LCR reduces the average response time by as much as 39.2% and 12.3%, respectively.",

"abstract": "Solid-state drives (SSDs) necessitate garbage collection (GC) to erase data blocks and reclaim the space of invalidated data, and GC inevitably introduces additional writes due to data relocation. The performance of GC, which is quantified by cleaning cost or write amplification, is critical to the overall performance of SSDs. However, characterizing GC performance is complicated by the general implementations of GC algorithms and the complex data locality characteristics of real-world workloads. This paper presents a general analytical study to characterize the performance impact of data locality on a general family of GC algorithms. We develop probabilistic models to address two fundamental issues: (1) What is the impact of data locality on the performance of locality-oblivious GC? (2) How can data locality be leveraged to improve the performance in locality-aware GC? We further conduct extensive trace-driven simulations on real-world workloads to validate the findings of our models.",

"abstract": "A lot of inexpensive disks in modern storage systems induce frequent disk failures. It takes a long time to recover a failed disk due to its large capacity and limited I/O. This paper proposes a hierarchical architecture of erasure code, OI-RAID. OI-RAID consists of two layers of codes, outer layer code and inner layer code. The outer layer code is based on disk grouping and Balanced Incomplete Block Design (BIBD) with skewed data layout to provide efficient parallel I/O of all disks for failure recovery. Inner layer code is deployed within a group of disks. As an example, we deploy RAID5 in both layers and present detailed performance analysis. With RAID5 in both layers, OI-RAID tolerates at least three disk failures meeting practical data availability, and achieves much higher speed up of disk failure recovery than existing approaches, while keeping optimal data update complexity and practically low storage overhead.",

"abstract": "Key-value (KV) stores are widely used to provide much higher read and write throughput than traditional SQL databases. In particular, LSM-tree based KV store is popular with many applications since it could eliminate random writes and thus provides good write performance. However, the data residing in external storage are compacted from time to time, which takes a large amount of I/O resources and degrades the system performance. In this paper, we propose FlameDB, which leverages grouped level structure (GLS) to mitigate the compaction overhead. Besides dividing the whole storage space into multiple components as in LSM-tree, GLS further divides each component into multiple groups and compacts all KV items in a component as a group of the next component. Besides, we also propose a heterogeneous bloom filter (HEBF) scheme which assigns more bits to the bloom filters in upper components. With HEBF, the false positive rate of a bloom filter in upper components become smaller, and this scheme reduces the expected number of I/Os to read a KV item from the external storage with a given memory usage. Our experiments show that FlameDB saves about 75% I/O during compaction, so it improves the write throughput by about four times. Meanwhile, the read performance is also slightly improved by deploying HEBF.",

"title": "Grouping-Based Elastic Striping with Hotness Awareness for Improving SSD RAID Performance",
"abstract": "RAID provides a good option to provide device-level fault tolerance. Conventional RAID usually updates parities with read-modify-write or read-reconstruct-write, which may introduce a lot of extra I/Os and thus significantly degrade SSD RAID performance. The recently proposed elastic striping scheme reconstructs new stripes with updated new data chunks without updating old parity chunks. However, it necessitates RAID-level garbage collection which may incur a very high cost. In this paper, we propose a hotness-aware caching scheme to buffer incoming writes and categorize data chunks in buffers into multiple groups according to their hotness values. We then propose a grouping-based elastic striping scheme to separately write data chunks in different groups into SSDs. We deployed the proposed schemes on a RAID-5 array composed of eight commercial SSDs, and experimental results show that compared to elastic striping, our scheme reduces 26% -- 65% of chunk writes to SSDs, and also reduces the average response time by 17.2% -- 63.9%.",

"title": "Efficient Parity Update for Scaling RAID-like Storage Systems.",
"abstract": "It is inevitable to scale RAID systems with the increasing demand of storage capacity and I/O throughput. When scaling RAID systems, we will always need to update parity to maintain the reliability of the storage systems. There are two schemes, read-modify-write (RMW) and read-reconstruct-write (RCW), to update parity. However most existing scaling approaches simply use RMW to update parity. While in many scenarios for existing scaling approaches, RCW performs better in terms of the number of scaling I/Os. In this paper, we propose an algorithm, called EPU, to analyze which of RCW and RMW is better for a scaling scenario and select the more efficient one to save the scaling I/Os. We apply EPU to online scaling scenarios and further use two optimizations, I/O overlap and access aggregation, to enhance the online scaling performance. Using Scale-CRS, one of the existing scaling approaches, as an example, we show via numerical studies that Scale-CRS+EPU reduces the amount of scaling I/Os over the traditional Scale-CRS in many scaling cases. To justify the online efficiency of EPU, we implement both Scale-CRS+EPU and Scale-CRS in a simulator with Disksim as a working module. Through extensive experiments, we show that Scale-CRS+EPU reduces the scaling time and the online response time of user requests over Scale-CRS.",

"title": "Analysis of Reliability Dynamics of SSD RAID.",
"abstract": "Solid-state drives (SSDs) have been widely deployed in desktops and data centers. However, SSDs suffer from bit errors, and the bit error rate is time dependent since it increases as an SSD wears down. Traditional storage systems mainly use parity-based RAID to provide reliability guarantees by striping redundancy across multiple devices, but the effectiveness of traditional RAID schemes in SSDs remains debatable. In particular, an open problem is how different parity distributions over multiple devices influence the reliability of an SSD RAID array. That is, should we evenly distribute patsaverties as suggested by conventional wisdom, or unevenly distribute parties as recently proposed for SSD RAID? To address this fundamental problem, we propose the first analytical model to quantify the reliability dynamics of an SSD RAID array as it ages. Specifically, we develop a “non-homogeneous” continuous time Markov chain model, and derive the transient reliability solution. We validate our model via trace-driven simulation and conduct numerical analysis to analyze the reliability dynamics of SSD RAID arrays subject to different parity distributions, error rates, and SSD array configurations. Our model enables system practitioners to decide the appropriate parity distribution based on their reliability requirements.",

"title": "Impact of Online Activities on Influence Maximization: A Random Walk Approach.",
"abstract": "With the popularity of OSNs, finding a set of most influential users so as to trigger the largest influence cascade is of significance. This task is usually modeled as an influence maximization problem, and it has been widely studied in the past decade. However, considering that users in OSNs may participate in various kinds of online activities, e.g., giving ratings to products, joining discussion groups, etc., influence diffusion through online activities becomes even more significant. Thus, it necessitates to revisit the influence maximization problem by taking online activities into consideration. In this paper, we study the impact of online activities by formulating the influence maximization problem for social-activity networks (SANs) containing both users and online activities. To address the computation challenge, we define an influence centrality via random walks on hypergraph to measure influence, then use the Monte Carlo framework to efficiently estimate the centrality in SANs, and use the Hoeffding inequality to bound the approximation error. Furthermore, we develop a greedy-based algorithm with two novel optimization techniques to find the most influential users. By conducting extensive experiments with real-world datasets, we show that compared to the state-of-the-art algorithm IMM [20], our approach improves the accuracy of selecting the top k most influential users in SANs by up to an order of magnitude, and our approach has a comparable computation time even though it needs to handle a large amount of online activities. Furthermore, our approach is also general enough to work under different diffusion models, e.g., IC and LT models, as well as heterogeneous systems, e.g., multiple types of users and online activities in SANs.",

"abstract": "Graphlets are induced subgraph patterns and have been frequently applied to characterize the local topology structures of graphs across various domains, e.g., online social networks (OSNs) and biological networks. Discovering and computing graphlet statistics are highly challenging. First, the massive size of real-world graphs makes the exact computation of graphlets extremely expensive. Secondly, the graph topology may not be readily available so one has to resort to web crawling using the available application programming interfaces (APIs). In this work, we propose a general and novel framework to estimate graphlet statistics of \\\"any size.\\\" Our framework is based on collecting samples through consecutive steps of random walks. We derive an analytical bound on the sample size (via the Chernoff-Hoeffding technique) to guarantee the convergence of our unbiased estimator. To further improve the accuracy, we introduce two novel optimization techniques to reduce the lower bound on the sample size. Experimental evaluations demonstrate that our methods outperform the state-of-the-art method up to an order of magnitude both in terms of accuracy and time cost.",

"abstract": "Metadata performance in distributed file systems (DFS) is critical, due to the following trends: (a) the growing size of modern storage systems is expected to exceed billions of files and most files are small; (b) over half of the file accesses are metadata operations. In this work, we present SMeta, a metadata prefetching method that is seamlessly integrated into DFS for easy-of-use and significantly scales the metadata performance. Previous prefetching proposals primarily focus on mining groups of files that tend to be accessed together from the access history. Nevertheless, our study discovered that these solutions likely miss a huge number of correlated files whose co-occurrence frequency is not high enough. Unlike access correlations, we take a novel and completely different approach to explore explicit data correlations by understanding the reference relationships between files encoded in some forms of hyperlinks, which naturally exist in many applications. To embrace this new concept, SMeta explores correlations upon files are written via a light-weight pattern matching algorithm, stores correlations in the reserved extended attributes of file metadata to avoid changes in DFS APIs, and collapses multiple I/O rounds for accessing metadata of the target file and its data-correlated files into one round. A cost-efficient adaptive feedback mechanism is introduced to improve prefetching accuracy. We implemented SMeta atop of Ceph and evaluated it using synthetic and real system workloads. Compared to baselines, SMeta provides better metadata performance in terms of latency, throughput and scalability.",

"title": "DSC: Dynamic stripe construction for asynchronous encoding in clustered file system.",
"abstract": "Nowadays many clustered file systems adopt asynchronous encoding which transforms replicated data into erasure coding to maintain data availability with bounded storage overhead. Existing implementations of asynchronous encoding construct coding stripes with logically sequential data blocks, which suffers from heavy cross-rack traffic and necessitates data block redistribution. Recent work [12] solves this problem by carefully distributing replicated data blocks among racks at the time when they are being written, but it is not applicable to the cases when existing systems have different data layouts or the data layout changes. In this paper, we propose Dynamic Stripe Construction (DSC) to transform N-way replication to erasure coding. DSC does not induce to any cross-rack traffic for encoding, and it does not require data block redistribution after encoding. Besides, DSC is general enough to be applied to any existing CFSes with various erasure codes, and it can also be deployed on a distributed file system in a hot-plugging-in manner. To validate the effectiveness of DSC, we implement it on HDFS. Through extensive testbed experiments in a real storage cluster, we show that DSC can significantly increase the encoding throughput and reduce the foreground user response time over the traditional approach.",

"title": "Modeling SSD RAID reliability under general settings.",
"abstract": "Solid-state drives (SSDs) are susceptible to the limited number of program/erase (P/E) cycles and uncorrectable flash errors, and hence achieving high reliability of SSD storage systems is a critical issue. RAID provides a viable option for enhancing system reliability by distributing redundancy across a number of SSDs. However, the flash error rate of an SSD increases with the number of P/E cycles, and this time-varying nature complicates the reliability analysis of SSD RAID. In addition, there remains very limited formal analysis that quantifies the reliability dynamics of an SSD RAID array under general settings. To this end, we propose a new continuous time Markov chain (CTMC) model to characterize the reliability dynamics of SSD RAID over time under two general settings: (1) fault tolerance against a general number of device failures and (2) non-uniform workload. We validate the correctness of our CTMC model via trace-driven simulations. Based on our model, we further analyze the impact of different RAID parameters on the reliability dynamics of an SSD RAID array.",

"abstract": "Persistent key-value (KV) stores mostly build on the Log-Structured Merge (LSM) tree for high write performance, yet the LSM-tree suffers from the inherently high I/O amplification. KV separation mitigates I/O amplification by storing only keys in the LSM-tree and values in separate storage. However, the current KV separation design remains inefficient under update-intensive workloads due to its high garbage collection (GC) overhead in value storage. We propose HashKV, which aims for high update performance atop KV separation under update-intensive workloads. HashKV uses hash-based data grouping, which deterministically maps values to storage space so as to make both updates and GC efficient. We further relax the restriction of such deterministic mappings via simple but useful design extensions. We extensively evaluate various design aspects of HashKV. We show that HashKV achieves 4.6x update throughput and 53.4% less write traffic compared to the current KV separation design. In addition, we demonstrate that we can integrate the design of HashKV with state-of-the-art KV stores and improve their respective performance.",

"abstract": "Data compression techniques have been deployed in SSDs to prolong their lifetime due to the good tradeoff between data reduction and performance degradation. However, existing schemes either consume plenty of DRAM resources, or cause the read amplification problem, which may further result in significant performance degradation. In this paper, we propose a lifetime-aware FTL scheme (LAFTL) to improve both the lifetime and performance of SSDs by compressing several pages into one physical page. We then design a compression-aware page mapping table (PMT) to reduce the memory consumption, and propose a latency-aware approach to improve the performance. We conduct extensive trace-driven evaluations based on real-world workloads, and results show that our LAFTL reduces the average response time of reads by 3%–78% and ensures a minimal resource consumption in DRAM while obtaining an acceptable data reduction rate compared to other schemes.",

"abstract": "Parity-based RAID poses a design trade-off issue for large-scale SSD storage systems: it improves reliability against SSD failures through redundancy, yet its parity updates incur extra I/Os and garbage collection operations, thereby degrading the endurance and performance of SSDs. We propose EPLOG, a storage layer that reduces parity traffic to SSDs, so as to provide endurance, reliability, and performance guarantees for SSD RAID arrays. EPLOG mitigates parity update overhead via elastic parity logging, which redirects parity traffic to separate log devices (to improve endurance and reliability) and eliminates the need of pre-reading data in parity computations (to improve performance). We design EPLOG as a user-level implementation that is fully compatible with commodity hardware and general erasure coding schemes. We evaluate EPLOG through reliability analysis and trace-driven testbed experiments. Compared to the Linux software RAID implementation, our experimental results show that our EPLOG prototype reduces the total write traffic to SSDs, reduces the number of garbage collection operations, and increases the I/O throughput. In addition, EPLOG significantly improves the I/O performance over the original parity logging design, and incurs low metadata overhead.",

In this paper, we consider the application of Markov modeling and mean-field analysis to solid-state drives (SSDs).

In particular, we focus on characterizing the performance---durability tradeoff of garbage collection (GC) algorithms in SSDs. Specifically, we first develop a stochastic Markov chain model to capture the I/O dynamics of large-scale SSDs, then adapt mean-field analysis to derive the asymptotic steady state, based on which we are able to easily analyze the performance---durability tradeoff of a large family of GC algorithms. We further prove the model convergence and generalize the model for all types of workload. Inspired by this model, we also propose a randomized greedy algorithm (RGA) which has a single tunable parameter to trade between performance and durability. Using trace-driven simulation on DiskSim with SSD add-ons, we demonstrate how RGA can be parameterized to realize the performance---durability tradeoff.",

"abstract": "Mining graphlet statistics is very meaningful due to its wide applications in social networks, bioinformatics and information security, etc. However, it is a big challenge to exactly count graphlet statistics as the number of subgraphs exponentially increases with the graph size, so sampling algorithms are widely used to estimate graphlet statistics within reasonable time. However, existing sampling algorithms are not scalable for large graphlets, e.g., they may get stuck when estimating graphlets with more than five nodes. To address this issue, we propose a highly scalable algorithm, Scalable subgraph Sampling via Random Walk (SSRW), for graphlet counts and concentrations. SSRW samples graphlets by generating new nodes from the neighbors of previously visited nodes instead of fixed ones. Thanks to this flexibility, we can generate any k-graphlets in a unified way and estimate statistics of k-graphlet efficiently even for large k. Our extensive experiments on estimating counts and concentrations of ({4,5,6,7})-graphlets show that SSRW algorithm is scalable, accurate and fast.",

To achieve this, the key issue is how to accurately identify hot data, which is really challenging due to the large diversity and dynamics of workloads. In this paper, we propose a light-weight and high-accuracy identification scheme, which is developed via a group of Least Recently Used (LRU) lists and requires only a small amount of memory and CPU cycles. We further deploy our scheme on SSDs with DiskSim simulator, and results show that comparing to two state-of-the-art identification schemes, our scheme further reduces SSD GC cost by up to 59.1 % (62.1 %), and saves 44.3 % (77.5 %) of computational cost. Due to the light-weight and parameter-insensitive feature, our scheme can be easily deployed at various system levels and adaptable to different workloads.",

Unfortunately, existing scaling algorithms fail to achieve this goal so they can not be applied for scaling RAIDs which have deployed parity declustering. To address this challenge, we develop an efficient scaling algorithm called PDS (Parity Declustering Scaling). In particular, we first employ an auxiliary Balanced Incomplete Block Design (BIBD) to define the data migrations during scaling so as to preserve parity declustered data layout, and then define the addressing algorithm in the scaled system based on the migrations. We provide theoretical proofs to show that PDS preserves the parity declustered data layout, which is the basis for scaling RAIDs with parity declustering, and also theoretically prove that PDS achieves the even distribution of data/parity blocks after scaling and requires only the minimal data migrations. To show the performance of PDS, we implement it in MD in Linux Kernel, and conduct experiments with real-world traces. Results show PDS can reduce 89.70% of data migration time and 24.44% of user response time during scaling on average, compared with the round-robin scheme.",

However, to perform scaling on such redundant array of inexpensive disks (RAIDs), it is necessary to preserve parity declustered data layout so as to preserve the properties after scaling. Unfortunately, existing scaling algorithms fail to achieve this goal so they cannot be applied for scaling RAIDs with parity declustering. To address this challenge, we develop an efficient online scaling scheme called parity declustering scaling (PDS), which employs an auxiliary balanced incomplete block design to define the data migration so as to preserve parity declustered data layout. Furthermore, PDS can also be applied to scale RAIDs for improving reliability and/or storage efficiency as options by allocating more parity blocks and/or data blocks in stripes. We provide theoretical proofs to formally show that PDS preserves parity declustered data layout, and achieves uniform distributions of data and parity blocks after scaling while requiring only the minimal data migration. We implement PDS in Linux kernel 3.14.72 and evaluate its performance with real-world traces. The results show that PDS can reduce 82.37 percent of scaling time and 18.25 percent of user response time during scaling on average, compared with “moving-everything” round-robin approach adapted to achieve parity declustered data layout after scaling.",

"title": "DCUDA - Dynamic GPU Scheduling with Live Migration Support.",
"abstract": "In clouds and data centers, GPU servers which consist of multiple GPUs are widely deployed. Current state-of-the-art GPU scheduling algorithm are \"static\" in assigning applications to different GPUs. These algorithms usually ignore the dynamics of the GPU utilization and are often inaccurate in estimating resource demand before assigning/running applications, so there is a large opportunity to further load balance and to improve GPU utilization. Based on CUDA (Compute Unified Device Architecture), we develop a runtime system called DCUDA which supports \"dynamic\" scheduling of running applications between multiple GPUs. In particular, DCUDA provides a realtime and lightweight method to accurately monitor the resource demand of applications and GPU utilization. Furthermore, it provides a universal migration facility to migrate \"running applications\" between GPUs with negligible overhead. More importantly, DCUDA transparently supports all CUDA applications without changing their source codes. Experiments with our prototype system show that DCUDA can reduce 78.3% of overloaded time of GPUs on average. As a result, for different workloads consisting of a wide range applications we studied, DCUDA can reduce the average execution time of applications by up to 42.1%. Furthermore, DCUDA also reduces 13.3% energy in the light load scenario.\n\n",

"title": "POS: A Popularity-based Online Scaling scheme for RAID-structured storage systems",
"abstract": "The ever-increasing demand of storage capability leads to scaling requirement in RAID-structured storage systems. Previous approaches to RAID scaling mainly focus on minimizing data migration, without considering the user-level application accesses. However, the mixed scaling I/Os and user accesses in practical systems will interfere with each other, which results in significant performance degradation of both the data migration time and the user response time. In this paper, we divide the whole storage space into multiple zones and measure the popularity (mainly using the metric of access frequency) of each zone. Based on the measured popularity, we propose an online scheme, namely Popularity-based Online Scaling (POS), to scale RAID-structured storage systems. The main idea of POS is to scale storage areas with high popularity first so as to better exploit workload locality. POS can efficiently alleviate the performance degradation of user response time and data migration time during the scaling process. It can be readily deployed atop various conventional RAID scaling approaches to improve their performance. To evaluate the performance of POS, we implement FastScale and FastScale with POS (POS-FS) in the same system. Through extensive benchmark studies on real-system workloads, we show that POS can efficiently reduce the response time to user requests and scaling I/Os and improve the sequentiality of data accesses.",

In this paper, we model OSNs as scale-free graphs (either with or without high clustering coefficient). We employ various influence mechanisms that govern the influence spreading in such large-scale OSNs and use the local mean field (LMF) technique to analyze these online social networks wherein states of nodes can be changed by various influence mechanisms. We extend our model for advertising with multiple rating levels. Extensive simulations are carried out to validate our models, which can provide insight on designing efficient advertising strategies in online social networks.",

"abstract": "Key-value stores are widely used to provide much higher read and write throughput than traditional SQL databases. LSMT (log structure merge tree) based key-value store, as one type of key-value stores, is applied in many practical systems since it could eliminate random writes and provide good read performance at the same time. However, the data residing in disk needs compaction operations from time to time, which takes a large amount of I/O resources. Since disk access speed is much slower than DRAM and most data resides in disks, the compaction operation will significantly influence the system performance. In this paper, we propose a grouped level structure, which divides each level in LSMT into multiple groups. Also, we propose a new compaction method for the grouped level structure to reduce the compaction I/O overhead. Our experiments show that the grouped level structure saves about 55% to 78% I/O resource of compaction, so it improves the write throughput by 69% to 284%, but only reduces the read throughput by 5% to 9%. It improves the overall throughput by 30% to 69% with read dominated workloads of 25% write operations and 75% read operations.",

"abstract": "Epidemic attack is a severe security problem in network-coding-enabled wireless mesh networks (WMNs). Malicious nodes can easily launch such form of attack to create an epidemic spreading of polluted packets and deplete network resources. The contribution of this work is to address such security problem. We allow the presence of \"smartâ attackers, i.e., they can pretend to be legitimate nodes to probabilistically transmit valid packets so as to reduce the chance of being detected. We also address the case where attackers cooperatively inject polluted packets. We employ the time-based checksum and batch verification to determine the existence of polluted packets, then propose a set of fully \"distributedâ and \"randomizedâ detection algorithms so that each legitimate node in a WMN can identify its malicious neighbors and purge them for future communication. We provide formal analysis to quantify the performance of the algorithms. Furthermore, simulation and system prototyping are carried out to validate the theoretic analysis and show the effectiveness and efficiency of the detection algorithms.",

"title": "Stochastic Modeling of Hybrid Cache Systems.",
"abstract": " In recent years, there is an increasing demand of big memory systems so to perform large scale data analytics. Since DRAM memories are expensive, some researchers are suggesting to use other memory systems such as non-volatile memory (NVM) technology to build large-memory computing systems. However, whether the NVM technology can be a viable alternative (either economically and technically) to DRAM remains an open question. To answer this question, it is important to consider how to design a memory system from a \"system perspective\", that is, incorporating different performance characteristics and price ratios from hybrid memory devices. This paper presents an analytical model of a \"hybrid page cache system\" so to understand the diverse design space and performance impact of a hybrid cache system. We consider (1) various architectural choices, (2) design strategies, and (3) configuration of different memory devices. Using this model, we provide guidelines on how to design hybrid page cache to reach a good trade-off between high system throughput (in I/O per sec or IOPS) and fast cache reactivity which is defined by the time to fill the cache. We also show how one can configure the DRAM capacity and NVM capacity under a fixed budget. We pick PCM as an example for NVM and conduct numerical analysis. Our analysis indicates that incorporating PCM in a page cache system significantly improves the system performance, and it also shows larger benefit to allocate more PCM in page cache in some cases. Besides, for the common setting of performance-price ratio of PCM, \"flat architecture\" offers as a better choice, but \"layered architecture\" outperforms if PCM write performance can be significantly improved in the future.

"title": "Balanced Parity Update Algorithm with Queueing Length Awareness for RAID Arrays.",
"abstract": "In parity-based RAID arrays, to update a data chunk, the corresponding parity chunk(s) must be updated accordingly so as to keep data consistency and availability. To achieve this, either read-modify-write (RMW) or read-constructwrite (RCW) could be used. Traditional parity update algorithm always selects the one requiring fewer pre-reads so as to reduce the total number of I/Os, but it may aggravate the skewness of I/O queues on disks, and thus degrades the system performance. In this paper, we propose a balanced parity update algorithm with queueing length awareness, BPU, which takes the number of pre-reads, the skewness of I/O queues on disks, and realtime workload into consideration when selecting RCW or RMW to update parity chunks. We implement a prototype system with BPU to evaluate its performance. Experimental results show that the length of I/O queues on disks in a RAID array may be highly skewed when using traditional parity update algorithm, and thus severely degrades the system performance. With BPU, we can reduce the average response time by up to 10%. We also study the performance of BPU under different system configurations, and provide multiple insights for adjusting the parameters of BPU so as to optimize its performance.",

"title": "Workload-Aware Elastic Striping With Hot Data Identification for SSD RAID Arrays.",
"abstract": "Redundant array of independent disk (RAID) offers a good option to provide device-level fault tolerance for solid-state drives (SSDs). However, parity update with either read–modify–write or read–reconstruct–write may introduce a lot of extra I/Os and thus significantly degrades SSD RAID performance. To reduce the parity update cost, elastic striping chooses to reconstruct new stripes with only the newly updated data chunks instead of directly updating parity chunks. However, it necessitates an RAID-level garbage collection (GC) process, which may incur a very high cost due to the mixture of hot and cold data chunks. To address this problem, we follow the idea of elastic striping and propose a workload-aware scheme (WAS) to reduce the RAID-level GC cost so as to improve the performance and endurance of SSD RAID. In particular, we first develop a novel lightweight hot data identification scheme which requires only a very small computation time and memory cost, then propose a hotness-aware elastic striping approach to separately write data chunks with different hotness to different regions in SSD RAID. To evaluate the effectiveness and efficiency of our WAS, we implement a prototype system on RAID-5 and RAID-6 arrays composed of commercial SSDs. Experimental results show that compared to original elastic striping, our scheme reduces 30.0%–70.6% (and 23.9%–63.2%) of chunk writes under the RAID-5 (and RAID-6) settings, and also reduces the average response time by 60.9%–79.3% (and 56.8%–80.9%) for RAID-5 (and RAID-6), respectively. Besides, our scheme also improves the endurance and reliability of SSD RAID compared to original elastic striping.",

"title": "SmartMD: A High Performance Deduplication Engine with Mixed Pages.",
"abstract": "In hypervisor-based virtualization environments, translation lookaside buffers (TLBs) misses may induce two-dimensional page table walks, which may incur a long access latency, and this issue becomes worse with ever increasing memory capacity. To reduce the overhead of TLB misses, large pages (e.g., 2M-pages) are widely supported in modern hardware platforms to reduce the number of page table entries. However, memory management with large pages can be inefficient in deduplication, leading to low utilization of memory, which is a precious resource for a variety of applications.To simultaneously enjoy benefits of high performance by accessing memory with large pages (e.g., 2M-pages) and high deduplication rate by managing memory with base pages (e.g., 4K-pages), we propose Smart Memory Deduplciation, or SmartMD in short, which is an adaptive and efficient management scheme for mixed-page memory. Specifically, we propose two lightweight schemes to accurately monitor pagesu0027 access frequency and repetition rate, and present a dynamic and adaptive conversion scheme to selectively split or reconstruct large pages. We implement a prototype system and conduct extensive experiments with various workloads. Experiment results show that SmartMD can simultaneously achieve high access performance similar to systems using large pages, and achieves a deduplication rate similar to that applying aggressive deduplication scheme (i.e., KSM) at the same time on base pages.",

"title": "Stochastic Analysis on RAID Reliability for Solid-State Drives",
"abstract": "Solid-state drives (SSDs) have been widely deployed in desktops and data centers. However, SSDs suffer from bit errors, and the bit error rate is time dependent since it increases as an SSD wears down. Traditional storage systems mainly use parity-based RAID to provide reliability guarantees by striping redundancy across multiple devices, but the effectiveness of RAID in SSDs remains debatable as parity updates aggravate the wearing and bit error rates of SSDs. In particular, an open problem is that how different parity distributions over multiple devices, such as the even distribution suggested by conventional wisdom, or uneven distributions proposed in recent RAID schemes for SSDs, may influence the reliability of an SSD RAID array. To address this fundamental problem, we propose the first analytical model to quantify the reliability dynamics of an SSD RAID array. Specifically, we develop a \"non-homogeneous\" continuous time Markov chain model, and derive the transient reliability solution. We validate our model via trace-driven simulations and conduct numerical analysis to provide insights into the reliability dynamics of SSD RAID arrays under different parity distributions and subject to different bit error rates and array configurations. Designers can use our model to decide the appropriate parity distribution based on their reliability requirements.",

"abstract": "Feedback-based reputation systems are widely deployed in E-commerce systems. Evidences showed that earning a reputable label (for sellers of such systems) may take a substantial amount of time and this implies a reduction of profit. We propose to enhance sellers' reputation via price discounts. However, the challenges are: (1) The demands from buyers depend on both the discount and reputation; (2) The demands are unknown to the seller. To address these challenges, we first formulate a profit maximization problem via a semiMarkov decision process (SMDP) to explore the optimal trade-offs in selecting price discounts. We prove the monotonicity of the optimal profit and optimal discount. Based on the monotonicity, we design a QLFP (Q-learning with forward projection) algorithm, which infers the optimal discount from historical transaction data. We conduct experiments on a dataset from to show that our QLFP algorithm improves the profit by as high as 50% over both the classical Q-learning and speedy Q-learning algorithm. Our QLFP algorithm also improves the profit by as high as four times over the case of not providing any price discount.",

We design UniKV, which unifies the key design ideas of hash indexing and the LSM-tree in a single system. Specifically, UniKV leverages data locality to differentiate the indexing management of KV pairs. It also develops multiple techniques to tackle the issues caused by unifying the indexing techniques, so as to simultaneously improve the performance in reads, writes, and scans.

"abstract": "System scaling becomes essential and indispensable for distributed storage systems due to the explosive growth of data volume. Considering that fault-protection is a necessity in large-scale distributed storage systems, and Cauchy Reed-Solomon (CRS) codes are widely deployed to tolerate multiple simultaneous node failures, this paper studies the scaling problem of distributed storage systems with CRS codes. In particular, we formulate the scaling problem with an optimization model in which both the post-scaling encoding matrix and the data migration policy are assumed to be unknown in advance. To minimize the I/O overhead, we propose a three-phase optimization scaling scheme for CRS codes. Specifically, we first derive the optimal post-scaling encoding matrix under a given data migration policy, then optimize the data migration process using the selected post-scaling encoding matrix, and finally exploit the Maximum Distance Separable (MDS) property to further optimize the designed data migration process. Our scaling scheme requires minimal data movement while achieving uniform data distribution. Moreover, it requires to read fewer data blocks than conventional minimum data migration schemes, but still guarantees the minimum amount of migrated data. To validate the efficiency of our scheme, we implement it atop a networked file system. Extensive experiments show that our scaling scheme uses less scaling time than the basic scheme.",

"abstract": "Random walk is widely applied to sample large-scale graphs due to its simplicity of implementation and solid theoretical foundations of bias analysis. However, its computational efficiency is heavily limited by the slow convergence rate (a.k.a. long burn-in period). To address this issue, we propose a common neighbor aware random walk framework called CNARW, which leverages weighted walking by differentiating the next-hop candidate nodes to speed up the convergence. Specifically, CNARW takes into consideration the common neighbors between previously visited nodes and next-hop candidate nodes in each walking step. Based on CNARW, we further develop two efficient \"unbiased sampling\" schemes. Experimental results on real-world network datasets show that our approach converges remarkably faster than the state-of-the-art random walk sampling algorithms. Furthermore, to achieve the same estimation accuracy, our approach reduces the query cost (a measure of sampling budget) significantly. Lastly, we also use two case studies to demonstrate the effectiveness of our sampling framework in solving large-scale graph analysis tasks.",

"title": "Improved stability and H∞ performance for neutral systems with uncertain Markovian jump",
"abstract": "This paper addresses the problem of the delay-dependent stability and H∞ performance for neutral systems with uncertain Markovian jump; the uncertainty of Markovian jump refers to the partial information on transition probability. In order to highlight the methods for the analysis of the systems, the neutral delay is assumed same as discrete delay. By the novel constructed Lyapunov functional, combining with the delay decomposition technique and free matrices, and using the new inequality rather than the Jensen inequality, the delay-dependent stability conditions are firstly obtained for the two kinds of neutral dynamical systems. Based on the stability condition, the H∞ performance result for the systems with Markovian jump is secondly provided. All of the delay-dependent stabilization results are formulated in terms of LMIs, which can be easily checked by the LMI control toolbox in Matlab. Finally, two numerical examples are given to show the validity and potential of the developed criteria.",

"abstract": "This paper considers the delay-dependent stability analysis of neutral-type Lur'e systems with time-varying delays and sector bounded nonlinearities. First of all, using constructed function methods, a new Jensen-like inequality is introduced to obtain less conservative results. Second, a new class of Lyapunov-Krasovskii functional (LKF) is constructed according to the characteristic of the considered systems. Third, combining with the new inequality and reciprocal convex approach and some other inequality techniques, the new less conservative robust stability criteria are shown in the form of linear matrix inequalities (LMIs). Finally, three examples demonstrate the feasibility and the superiority of our methods.",

"abstract": "Background/Aims: Restenosis following extracranial artery stenting is a limitation that affects long-term outcomes. Effective and satisfying pharmacological strategies in preventing restenosis have not been established. This study aimed to evaluate whether argatroban, a direct thrombin inhibitor, could reduce the risk of in-stent restenosis after extracranial artery stenting. Methods: One hundred and fourteen patients hospitalized between August 2010 and August 2011 were enrolled. Patients were randomly assigned to argatroban (n = 58) and blank control groups (n = 56). The patients in the argatroban arm were treated with 10 mg of intravenous argatroban twice daily 2 days before and 3 days after the stenting procedures. Patients were followed for 12 months after the procedure. During follow-up, restenosis and target revascularization were analyzed. Recurrent cerebrovascular and cardiovascular events and deaths were also compared between the groups. Results: One patient in the stenting group withdrew immediately after the procedure due to unsuccessful stenting. Restenosis occurred in 4 patients (7.4%) in the argatroban group and in 11 patients (21.6%) in the control group during the 6- to 9-month angiographic follow-up period (p = 0.032). Nine months after the procedures, argatroban-treated patients had a trend towards a lower incidence of target revascularization compared with the controls (5.4 vs. 13.7%, p = 0.188). No major bleeding events or other adverse events occurred in the argatroban group. Conclusion: This pilot clinical trial is the first that uses argatroban to prevent restenosis in ischemic cerebrovascular disease, and suggests that intravenous administration of argatroban is effective and safe in preventing restenosis after extracranial artery stenting. Larger randomized controlled clinical trials are warranted. (C) 2014 S. Karger AG, Basel",

"abstract": "ObjectiveTo identify the specific caseload to overcome learning curve effect based on data from consecutive patients treated with Intracranial Angioplasty and Stenting (IAS) in our center. BackgroundThe Stenting and Aggressive Medical Management for Preventing Recurrent Stroke and Intracranial Stenosis trial was prematurely terminated owing to the high rate of periprocedural complications in the endovascular arm. To date, there are no data available for determining the essential caseload sufficient to overcome the learning effect and perform IAS with an acceptable level of complications. MethodsBetween March 2004 and May 2012, 188 consecutive patients with 194 lesions who underwent IAS were analyzed retrospectively. The outcome variables used to assess the learning curve were periprocedural complications (included transient ischemic attack, ischemic stroke, vessel rupture, cerebral hyperperfusion syndrome, and vessel perforation). Multivariable logistic regression analysis was employed to illustrate the existence of learning curve effect on IAS. A risk-adjusted cumulative sum chart was performed to identify the specific caseload to overcome learning curve effect. ResultsThe overall rate of 30-days periprocedural complications was 12.4% (24/194). After adjusting for case-mix, multivariate logistic regression analysis showed that operator experience was an independent predictor for periprocedural complications. The learning curve of IAS to overcome complications in a risk-adjusted manner was 21 cases. ConclusionsOperator's level of experience significantly affected the outcome of IAS. Moreover, we observed that the amount of experience sufficient for performing IAS in our center was 21 cases. (c) 2013 Wiley Periodicals, Inc.",

Methods: A series of 33 consecutive patients (mean age, 40.21 years; 29 men and 4 women) who underwent angioplasty and stent placement for symptomatic carotid artery dissection (sCAD) from May 2005 to December 2010 in the Nanjing Stroke Registry Program (NSRP) was retrospectively reviewed. All the included patients had been diagnosed definitively based on catheter angiography, and had failed to respond to medical therapy during the course of initial hospital admission. The baseline and followed up data of these patients were collected and analyzed. Results: Of all the 33 included patients, 32 patients had achieved technical success without any intraoperative complications. Two patients manifested ipsilateral Horner sign on the next day after stenting, and one of them suffered from recurrence of transient ischaemic attack (TIA) during the course of follow up, but completely remission via antithrombotic therapy.

"abstract": "In this study, we aimed to evaluate the safety and feasibility of simultaneous bilateral carotid artery stenting (BCAS) compared with staged BCAS in patients with bilateral atherosclerotic carotid stenosis (BCS). From January 2004 to March 2012, 68 patients who underwent BCAS were identified from the Nanjing Stroke Registry Program. Of these patients, 42 (61.8 %) underwent simultaneous BCAS (simultaneous group), and 26 (38.2 %) underwent staged BCAS (staged group). We compared demographic data, major vascular risk factors, procedural parameters, and 30 day outcomes between the simultaneous and staged groups. No significant differences were detected in baseline data between the groups. Patients in the simultaneous group had a lower post-operative systolic pressure compared with the staged group (119.1 �� 16.1 vs. 130.2 �� 17.5 mmHg, P = 0.009). Technical success was 100 % of patients in the simultaneous group and 98.1 % in the staged group. Hemodynamic depression was observed in 57.4 % of procedures, with no significant difference between groups in the rate of HD. Four (5.9 %) patients had neurological complications within 30 days, including two cases of hyperperfusion syndrome in the simultaneous group, and two ischemic events in the staged group. There was no significant difference in the 30 day complication rate between the simultaneous and staged groups (4.8 vs. 7.7 %, P = 0.633). Simultaneous BCAS may be safe and feasible for most patients with BCS, with a similar 30 day complication rate to staged BCAS. Multicenter randomized control studies with larger sample sizes are warranted to further explore the safety and efficacy of simultaneous BCAS. ? 2013 Springer Science+Business Media New York.",

"abstract": "Objective: To evaluate the impact of cytochrome P450 (CYP) 2C19 gene polymorphisms on clinical outcome in clopidogrel-treated patients who underwent cerebrovascular stenting placement. Methods: One hundred and ninty-four patients who underwent cerebrovascular stent placement and with long-term treatment of clopidogrel (75 mg/d) between April 2009 and December 2010 were enrolled, CYP2C19 genotype was detected by improved multiple ligase detection reaction. The primary clinical endpoints were ischemic stroke and death after stent implantation; the key secondary endpoints were hemorrhagic stroke and other vascular events. Results: The average followed-up was (19.4 ±9.9) months. The overall incidence of primary endpoints was 16.5%. Of the 194 patients, 87(44.8%) were wild-type homozygous, 88 (45.4%) were heterozygotes, and 19 (9.8%) were homozygous. The cumulative incidence of adverse outcomes was significant higher in CYP2C19* 2 carrier than that in noncarriers (22.4% (24/107) vs 9.2% (8/87), HR=2.74, 95% CI 1.23-6.10, P = 0.01). Of the 194 patients, 13 (6.7%) were heterozygotes, and 181 (93.3%) were wild-type homozygous. CYP2C19* 3 polymorphism had no significant impact on the outcomes in this cohort of patients. No relationship between gene and the secondary endpoints were detected. After multivariable analysis, the CYP2C19* 2 was an independent predictor of clinical outcomes of cerebrovascular stent placement (HR = 2.89, 95% CI 1.10-7.60, P = 0.03). Conclusions: CYP2C19* 2 is an independent determinant of adverse events after cerebrovascular stent placement treated with clopidogrel. While CYP2C19* 3 is not associated with the clinical prognosis in patients with cerebrovascular stent placement. Copyright © 2013 by the Chinese Medical Association.",

"abstract": "Cervical and intracranial angioplasty and stenting is an effective and safe method of reducing the risk of ischemic stroke, but it may be affected by in-stent restenosis. The present study investigated serum level of matrix metalloproteinase 9 as a predictor of restenosis after 40 patients underwent cervical and/or intracranial angioplasty and stenting. Results showed that restenosis occurred in 30% (3/10) of patients when the serum level of matrix metalloproteinase 9 at 3 days after surgery was 2.5 times higher than preoperative level. No restenosis occurred when the serum level of matrix metalloproteinase 9 at 3 days after surgery was not 2.5 times higher than preoperative level. Restenosis occurred in 12% (2/17) of patients when the serum level of matrix metalloproteinase 9 was higher than preoperative level for more than 30 days after surgery, but only occurred in 4% (1/23) of patients when the serum level of matrix metalloproteinase 9 was higher than preoperative level for less than 30 days after surgery. However, the differences observed were not statistically significant (P > 0.05). Experimental findings indicate that when the serum level of matrix metalloproteinase 9 is 2.5 times higher than preoperative level at 3 days after cervical and intracranial angioplasty and stenting, it may serve as a predictor of in-stent restenosis.

"abstract": "Objective: To investigate the value of hyperintense vessel signs (HVS) on fluid-attenuated inversion recovery (FLAIR) sequence for assessing the patterns of collateral blood flow in adult moyamoya disease (MMD). Methods: Forty-one adult patients with non-hemorrhagic MMD retrieved from Nanjing Stroke Registry Program between August 2008 and January 2011 were identified by digital cerebral angiography and performed the examination of FLAIR sequence in Jinling hospital. According to the different sites of HVS located in the territory of the middle cerebral artery, the patterns of HVS were classified into grades 0-3; Grade 0, absence of HVS; Grade 1, HVS limited in the cerebral sulci of temporal lobe and Sylvian fissure; Grade 2, HVS in the cerebral sulci of frontal and parietal lobe regions and Sylvian fissure; and Grade 3, HVS in the combined territories of Grade 1 and Grade 2. According to the intracerebral collateral blood flow, steno-occlusions of the arteries were classified into three types; Type 1, residual antegrade flow across steno-occlusive lesions; Type 2, retrograde flow via leptomeningeal vessels; Type 3, the combined collateral blood flow of Type 1 and Type 2. The relationship between the patterns of intracerebral collateral blood flow and the location of HVS was analyzed. Results: Of 41 adult patients with non-hemorrhagic MMD, there were 3 patients presented with unilateral vascular lesions and 38 with bilateral vascular lesions, so the total number of vascular lesions of the cerebral hemispheres was 79. Because three patients showed the absence of HVS in bilateral hemispheres, the total number of the presence of HVS of the cerebral hemispheres was 73. Therefore, the percentage of the presence of HVS was 92.4% (73/79) in vascular lesions of the cerebral hemispheres. Importantly, the patterns of slow collateral blood flow corresponding to Grade 1 HVS were all antegrade (7/7); the collateral patterns corresponding to Grade 2 HVS were mainly retrograde leptomeningeal flow (95.0%, 19/20); and the patterns corresponding to Grade 3 HVS were mainly slow combined collateral blood flow(84.8%, 39/46). Furthermore, with the changing sites of HVS from the cerebral sulci of temporal lobe to the cerebral sulci of frontal and parietal lobe regions, the directions of collateral flow changed with a shift from antegrade to retrograde, which was statistically significant. Conclusion: The different locations of HVS can reflect the different patterns of collateral blood flow, and the locations of HVS may predict the directions of intracerebral collateral blood flow in adult MMD patients.",

"abstract": "Cerebral microbleeds (CMBs) are the important indicators of cerebral small vessel disease. However, it is still unclear whether endothelial dysfunction is involved in CMBs. In this study, we performed a prospective study to investigate the correlation between sE-selectin (soluble E-selectin) or adiponectin and the prevalence of CMBs.We recruited 133 consecutive patients with first-ever ischemic stroke for this study. Finally, 126 patients were analyzed. The number and presence of CMBs were detected and evaluated on susceptibility-weighted magnetic resonance imaging within two weeks after symptom onset. We assessed the serum levels of adiponectin and sE-selectin for patients.CMBs were detected in 63 subjects (50%) within 126 patients and more prevalent in mixed brain regions (55.6%). In binary logistic regression analysis, each 1SD-increase in adiponectin level was significantly conversely associated with the prevalence of CMBs after adjusting for age, sex and cardiovascular risk factors (OR = 0.55; 95% CI: 0.36-0.84); but sE-selectin was significantly positively associated with the prevalence of CMBs (OR = 1.09; 95% CI: 1.02-1.15). Furthermore, partial correlation analyses showed that sE-selectin remained significantly associated with and correlated conversely to adiponectin (r = -0.452, p = 0.001).Endothelial injury may play a role in the pathogenesis of CMBs, and serum levels of adiponectin and sE-selectin were closely related to CMBs. Adiponectin might be protective for the prevalence of CMBs.",

"title": "The long-term outcome of endovascular treatment versus medical treatment for severe intracranial artery stenosis of anterior circulation",
"abstract": "Objective: To compare long-term outcome by endovascular treatment and medical treatment in severe intracranial atherosclerotic stenosis of anterior circulation. Methods: Consecutive patients in Nanjing Stroke Registry Program who had transient ischemic attack or stroke attributed to severe intracranial atherosclerotic stenosis of anterior circulation were retrospectively reviewed. Patients were either treated with endovascular therapy (endovascular treatment group) or with medicine (medical treatment group). The primary endpoint was any stroke or death within 30 days after enrollment and ischemic events in the territory of qualifying artery beyond 30 days after a revascularization procedure for the qualifying lesion. The secondary endpoint was stroke in territory of qualifying artery beyond 30 days. The cumulative event rates were compared between two groups and identifying the independence risk factors of secondary endpoint. Results: Of the 142 patients enrolled, 69 patients were in endovascular treatment group and 73 patients in medical treatment group. The cumulative event rates of a primary endpoint over time in 30-day, 1-year, 2-year, 3-year in endovascular treatment group and in medical treatment group were 13%, 15%, 21%, 29% and 1%, 15%, 22%, 27%, respectively. The occurrence was not statistically different between two groups. The occurrences of a secondary endpoint in endovascular treatment group and in medical group at 1-year, 2-year, 3-year were 5%, 13%, 15% and 14%, 21%, 34% respectively, and those in endovascular treatment group was significantly lower (P=0.026). Multivariate Cox analysis revealed that therapeutic modality (HR=2.601, 95% CI 1.042-6.495, P=0.041) and the number of major vascular risk factors (HR=3.322, 95% CI 1.116-9.894, P=0.031) are independence risk factors for stroke in territory of qualifying artery beyond 30 days. Conclusions: The long-term results from endovascular treatment for anterior circulation severe intracranial atherosclerotic stenosis had no statistical difference comparing with that of medical treatment. But the effect of endovascular treatment in preventing stroke in territory of qualifying artery was superior to medical treatment beyond 30 days.

"abstract": "Endothelial progenitor cells (EPCs) are novel markers of endothelial dysfunction and are related to cardiovascular disease. However, their relationship with cerebral atherosclerosis (CA) has not been investigated extensively. We aim to study the relationship between CA severity and EPC subpopulations levels.We enrolled 197 patients in this study. EPCs were measured by flow cytometry. Digital subtraction angiography was used to assess CA. Arterial lesion severity was evaluated among cerebral arteries which showed steno-occlusion change and the extent of that condition.There was a significant inverse correlation between EPCs level and CA prevalence after adjusting for confounders (CD45(-/dim)CD34(+)CD309(+) cells: odds ratio [OR], 0.110; 95% confidence interval [CI], 0.026-0.475; P = .00; CD45(-/dim)CD133(+)CD309(+) cells: OR, 0.134; 95% CI, 0.030-0.599; P = .01; CD45(-/dim) CD34(+)CD133(+)CD309(+) cells: OR, 0.010; 95% CI, 0.001-0 .541, P = .02). Multivariate logistic regression analysis showed that only the EPCs level was significantly inversely associated with extracranial atherosclerosis rather than intracranial atherosclerosis (P > .05).Our data indicated that EPCs subpopulations were independent predictors for CA severity, even after controlling for traditional risk factors.",

"abstract": "This study aimed to evaluate the efficacy and safety of stereotactic aspiration combined with subsequent thrombolysis in treating moderate thalamic hemorrhage (TH).A total of 105 patients with TH were nonrandomly assigned to the conservative treatment group (n = 60) or to the aspiration group (n = 45). Patients in the aspiration group were treated with stereotactic aspiration plus subsequent thrombolysis for removal for their hematomas.The 30-day mortality in the conservative group was significantly higher than that in the aspiration group (28.3% (17/60) vs. 11.2% (5/45), P = 0.032). The rank of the 30-day Glasgow outcome scale in the conservative group was significantly lower than that in the aspiration group (P = 0.041), and the mean 30-day National Institutes of Health Stroke Scale score of the survivors in the conservative group was significantly higher than that in the aspiration group (16.5 ± 4. 2 vs. 14.2 ± 3.9, P = 0.012). There were a greater reduction in TH volume in the aspiration group than in the conservative group from day 1 to day 3 (-0.24% and 39.28%, respectively, P < 0.0001) and from day 1 to day 7 (26.58% and 63.26%, respectively, P < 0.0001). The rank of 90-day Glasgow outcome scale was significantly lower in the conservative group than that in the aspiration group (P = 0.015). Eighteen of 60 patients (30.0%) had a favorable outcome in the conservative group, whereas 23 of 45 patients (51.1%) had a favorable outcome in the aspiration group, and this difference was significant (P = 0.028). The 90-day cumulative mortality rate in the conservative group was significantly higher than that in the aspiration group (33.3% (20/60)) vs. 15.6% (7/45), P = 0.039).Stereotactic aspiration plus subsequent thrombolysis is effective and safe for moderate TH.",

"abstract": "Background and Purpose: Craniocervical artery stenosis is an important etiology for transient ischemic attack (TIA). We hypothesized ABCD and ABCD2 scores can predict craniocervical artery stenosis in patients with TIA. Methods: ABCD and ABCD2 scores were calculated in a total of 479 consecutive first-ever TIA patients in Nanjing Stroke Registry Program and compared with angiographic imaging derived from MRI or invasive catheter-based angiography. Results: Overall craniocervical artery (O-CA) stenosis was found in 197 (41.1%) patients. Extracranial craniocervical artery (E-CA) and intracranial craniocervical artery (I-CA) stenosis was found in 101 (21.1%) and 110 (23%) cases, respectively. ABCD and ABCD2 scores with similar accuracy for O-CA (AUC(ABCD) 0.71, AUC(ABCD2) 0.70), E-CA (AUC(ABCD) 0.72, AUC(ABCD2) 0.72) and I-CA stenosis (AUC(ABCD) 0.62, AUC(ABCD2) 0.62) were both independent predictors for various categories of artery stenosis after being adjusted for non-ABCD2 parameters. The cut-off points were equally 4 in both predicting rules. For ABCD, sensitivity was 57.4, 65.3 and 52.7% and specificity 77.0, 70.4 and 67.5% for O-CA/E-CA/I-CA, respectively. For ABCD2, sensitivity was 61.9, 69.3 and 58.2% and specificity 72.3, 65.6 and 63.1%. Conclusions: In patients with TIA, despite an association between ABCD and ABCD2 scores and underlying craniocervical artery stenosis, the clinical utility was limited by unsatisfactory sensitivity and specificity.

"abstract": "Background: To investigate the correlation between tortuosity of extracranial internal carotid artery (EICA) and intraprocedural complications in patients undergoing carotid artery stenting (CAS). Methods: The study included 244 EICA in 223 patients undergoing CAS. Tortuosity in EICA was measured by the tortuosity index (TI). Multivariate logistic regression was performed to assess the independent risk factors of vasospasm during CAS. Receiver operating characteristic curve was performed to identify the cut-off of TI to predict vasospasm. Results: During the 244 CAS, 71 EICA presented vasospasm and 114 CAS presented hypotension. High TI, long procedural duration and female are independent risk factors for vasospasm during CAS. TI of 118 was the optimal cut-off to predict vasospasm during CAS (sensitivity: 85.9%, specificity: 78.6%). Linear regression analysis demonstrated that TI is positively correlated with procedural duration (p < 0.001). There was no significant difference in TI between the hypotension and non-hypotension groups (p = 0.145). Conclusion: TI is an independent risk factor for vasospasm during CAS and a TI >= 118 has the high sensitivity and specificity to predict vasospasm. Our results indicate the value of assessing tortuosity of EICA prior to choosing or performing the procedure in patients with carotid stenosis or occlusion. Copyright (C) 2012 S. Karger AG, Basel",

"abstract": "Atherosclerotic subclavian artery stenosis (SAS) accompanied with other craniocervical artery stenosis (OCAS) is not uncommon in practice. We sought to investigate the safety and efficacy of endovascular stenting for SAS in patients with OCAS. Between January 2004 and February 2012, 71 consecutive atherosclerotic SAS patients who underwent primary stenting in our medical center were included. The enrolled patients were divided into combined-SAS group (n = 51) and solitary-SAS group (n = 20) depending on the presence or absence of OCAS. Data of demographics, procedure, and the followed-up were retrieved and analyzed. The technical success rate was 95.8%; the clinical success rate was 90.1%. There was no catheter-related major stroke or death. The immediate outcomes had no statistical difference between groups. During a mean of 27 ± 20 months (range 2-88 months) followed-up, 7 (10.3%) restenosis and 12 (17.6%) clinical events were identified. The primary patency rate was 95.3, 84.9 and 84.9% at 12, 24 months, and final followed-up respectively, which had no statistical difference between groups (odds ratio (OR), 2.60; 95% confidence interval (CI), 0.54-12.53; P = 0.232). The overall clinical event-free survival rate was 93.5, 86.2 and 54.6%, respectively, where the result of combined-SAS group was inferior to that of the solitary-SAS group (OR, 3.34; 95% CI, 1.02-11.00; P = 0.047). Endovascular stenting was safe and feasible for atherosclerotic SAS in patients with OCAS, although the combined OCAS may have a significant influence on the long-term outcome. Further studies are warrant to investigate the effects of revascularization for multiple craniocervical artery stenoses on the cerebral hemodynamics and long-term outcomes.",

All patients were tested for plasma homocysteine when polysomnography was finished at (14 +/- 2) d after the onset of IS.The mean level of homocysteine was significantly higher in the OSA group than that in the non-OSA group (17 +/- 5 vs 11 +/- 3 micromol/L, P < 0.01). Pearson correlation analysis revealed a positive correlation between the homocysteine level and the severity of AHI (r = 0.482, P < 0.01). Further multiple linear regression analysis showed that AHI and folate were independent predictors of homocysteine level (R2 = 0.553, P < 0.01, beta for AHI = 0.671, beta for folate = -0.256).The severity of OSA is significantly associated with an elevated level of homocysteine in IS patients. And this association is independent of other causative factors of an elevated level of homocysteine.",

"abstract": "The photoelectrochemical water splitting into hydrogen and oxygen using sun light is a potentially clean and renewable source of hydrogen fuel. TiO2 nanotubes (NTs) grown by anodization in a fluoride based electrolyte were loaded with Ni oxide nanoparticles by a pulse electrodeposition method. The fabricated NiOx/TiO2NTs electrodes were characterized by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDS) and X-ray photoemission spectroscopy (XPS). The photoelectrochemical property of fabricated NiOx/TiO2NTs electrodes was characterized by using a compartment cell. It was found that the Ni oxide nanoparticles loaded enhanced the visible spectrum absorption of the TiO2 nanotube arrays, as well as their solar-spectrum induced photocurrents, while a reverse result was obtained under UV-light illumination.

Various physicochemical parameters for zeolite template and/or IrxRu1−xO2 were obtained by SEM, TEM, XRD, EDX and N2 gas absorption/desorption measurements. The morphology for prepared IrxRu1−xO2 samples with individual and/or cluster nanorods was changed with the component difference. Cyclic voltammetry, linear sweep voltammetry, electrochemical impedance spectroscopy, steady state polarization curves and stability tests were performed to investigate the catalytic activity and stability of these electrocatalysts for OER. The cell with catalyst RuO2 showed best catalytic performance with the lowest onset potential (1.374 V at 10 mA cm−2), which may be ascribed to regular nanoclusters and larger outer active surface area. Meanwhile, the cell stability tests suggested that the addition of IrO2 in IrxRu1−xO2 improved the stability of the RuO2 catalyst.",

"abstract": "An oriented ultrathin catalyst layer (UTCL) has been prepared for fuel cells application based on the high electrical conductivity TiO2 nanotube (TNTs). The electrical conductivity of TNTs was improved by the deposited C via a plasma enhanced chemical vapor deposition (PECVD) technique. Pt catalysts were deposited on the high electrical conductivitve TNTs by the radio frequency (RF) sputtering to form the oriented C-TNTs-Pt electrode. The mass activity of C-TNTs-Pt-1 at 0.85V was about 0.44AmgPt−1. The prepared oriented UTCL based on the C-TNTs-Pt electrode displayed a maximum power density of 206 and 305mWcm−2 at an ultralow Pt loading resulting in a relatively high Pt utilization of 8.3 and 6.0kWg−1Pt. A 2D symmetry model based on the parameters of the oriented UTCL was established. In the model, the performance of fuel cell was improved along with the decreasing of CL thickness. Meanwhile, it is found that there is little effect on the cell performance when the electrical conductivity of CL is larger than 3Scm−1. The study in this work gave effectual evidence on the possibility of using the oriented UTCL for developing low cost fuel cells.",

"abstract": "We developed an advanced surfactant-assistant method for the IrxSn1-xO2 (0 < x <= 1) nanoparticle (NP) preparation, and examined the OER performances by a series of half-cell and full-cell tests. In contrast to the commercial Ir black, the collective data confirmed the outstanding activity and stability of the fabricated IrxSn1-xO2 (x = 1, 0.67 and 0.52) NPs, which could be ascribed to the amorphous structure, good dispersion, high pore volume, solid-solution state and Ir-rich surface for bi-metal oxides, and relatively large size (10-11 nm), while Ir0.31Sn0.69 exhibited poor electro-catalytic activity because of the separated two phases, a SnO2-rich phase and an IrO2-rich phase. Furthermore, compared with highly active IrO2, the improved durability, precious-metal Ir utilization efficiency and correspondingly reduced Ir loading were realized by the addition of Sn component. When the Ir0.52Sn0.48O2 cell operated at 80 degrees C using Nafions (R) 115 membrane and less than 0.8 mg cm(-2) of the noble-metal Ir loading, the cell voltages we achieved were 1.631 V at 1000 mA cm(-2), and 1.821 V at 2000 mA cm(-2). The IR-free voltage at the studied current density was very close to the onset voltage of oxygen evolution. The only 50 mu V h(-1) of voltage increased for the 500 h durability test at 500 mA cm(-2). In fact, these results are exceptional compared to the performances for OER in SPEWE cells known so far. This work highlights the potential of using highly active and stable IrO2-SnO2 amorphous NPs to enhance the electrolysis efficiency, reduce the noble-metal Ir loading and thus the cost of hydrogen production from the solid polymer electrolyte water electrolysis.",

The results showed that the average concentration of all these eight heavy metals were higher than their background values of Guangdong Province. Coefficients of variation of Cd and Hg reached as high as 115% and 151% respectively,coupling with high concentrations,which suggested anthropogenic sources of these elements. Cr,Ni and Cu displayed low coefficients of variation,thus suggesting a major natural source. The combination of multivariate statistical and Fourier spectral analysis methods successfully identified the elements Pb,Zn,As,Cd and Hg from anthropogenic sources and Cr,Ni and Cu from natural source. Furthermore,Fourier spectral analysis not only interpreted the double sources of Zn and Cu,but also inferred that atmosphere deposition could be an important source of Hg enrichment in soil. According to the pollution evaluation,21.7 percent of the study area is suffered from moderate and severe pollution,indicating the requirement of modifications in agricultural cultivation practices in these areas.",

"abstract": "In Shunde District of Foshan City,Pearl River Delta Economic Zone,208 topsoil samples and 114 vegetable samples were collected from vegetable fields to measure the contents of lead (Pb) ,which species of 38 topsoil samples were extracted.The results showed that the average concentration of heavy metal Pb was 44.3mg/kg.The contents of soil lead that exceeded Guangdong Province soil background values accounted for 77.5%,,the content of lead in vegetable that exceeded safety requirements for non-en-vironmental pollution vegetable accounted for 74.6%.The accumulation tendency of soil Pb of study area in the future 10 years was predicted based on the accumulation rate of soil Pb in 2007 which equaled to 1.02mg/kg.Early-warning for the accumulation tendency of soil Pb were done based on the threshold values 150、270、300 and 8580mg/kg,respectively.The scale which soil Pb in excess of 150mg/kg was increased during 2007-2017 years,however,the scales were increased,which soil Pb in excess of 270、300mg/ kg,respectively.There was a significant relation between the transfer factor values and the corresponding soil Pb concentrations (full dosage or bioavailable amount),which can be described by a plateau model.The target hazard quotients (THQs) can be used to evaluate the health risks with heavy metals by consuming vegetable.The THQs of Pb in vegetables were below 0.4 that values from large to small were THQhigh>THQurban >THQmedian> THQrural>THQlow,which indicated that the health risk via vegetable consumption in the high levels of family economic income was the highest.Moreover,further researches about influence of Pb on the human health through other exposure paths should be done.",

"abstract": "The Pearl River Delta Economic Zone(PRDEZ) is one of the most developed areas economically and socially in China,and its eco-geochemical environment is heavily affected by human activities.In this paper,net flux of soil heavy metals is estimated on regional input-output flux model,and then prediction and early-warning forecast on geochemical accumulation of soil heavy metals is carried out.Early warning forecast is conducted by the factor pollution index obtained from the Probability Kriging model which integrates the space distribution and probability distribution of soil heavy metals.The concentration threshold for warning factor is taken from the China National Environmental Quality Standards for the level-II soil.It is shown that Cd,Hg,Ni and Cr are the main eco-geochemical warning factors for the paddy land soil,Cd,Hg and Ni factors for the dry land,and As,Cr and Ni for the garden land.With the present development model going until the year of 2025,the heavily warning regions of paddy land soil will extend to the Pengjiang District,Jianghai District and Xinhui District in Jiangmen City,Kaiping,Heshang,Zhongshan,Nansha Districts,Panyu District in Guangzhou City,Dinghu District,Duanzhou District and Gaoyao District in Zhaoqing City,and Doumen District in Zhuhai City.The heavily warning regions of dry land soil will extend to Panyu District,Nansha District,Baiyun District,Huangpu District,Luogang District and Huadu District in Gangzhou City,Gaoming District,Nanhai District,Shunde District and Shancheng District in Foshan City,Sihui District in Zhaoqing City,Xiaolan District,Guzhen District,Sanjiao District and Dongshen District in Zhongshan City,Doumen District and Jinwandeng District in Zhuhai City,and Xinhui,Kaiping and Taishan in Jiangmen City.The heavily warning regions of garden land soil will extend to Nansha District,Panyu District and Huadu District in Guangzhou City,the northern Huidong County in Huizhou City,Doumen District,Jinwan District and Tanzhou District in Zhuhai City,and Shunde District,Nanhai District,Shancheng District and Sanshui District in Foshan City.",

"title": "Distributional characteristics and sources of elements in soil from typical area of Pearl River Delta economic zone, Guangdong Province, China",
"abstract": "Dongguan City, located in the Pearl River Delta economic zone of China, is famous for its rapid developing township-enterprises in the past 30 years. A total of 759 composite soil samples, including 606 surface soil samples and 153 deep soil samples, have been collected in the city. These samples have been analyzed for 13 elements (Al, As, Cu, Cd, Co, Cr, Fe, Hg, Mn, Ni, Pb, Si, and Zn) and other parameters (pH values and organic matter) to evaluate the influence of anthropic activities on the soil environmental quality and to identify the spatial distribution of heavy metals and their possible sources. The results indicate that the average concentrations of heavy metals in soil were significantly lower than the threshold of the second grade of the Soil Environment Quality Standard in China (GB15618-1995) and the soil environmental quality in this area is comparatively good. But in comparison with local soil geochemical baseline values, As, Cd, Cu, Hg, Pb, and Zn have accumulated remarkably. Specifically, the average concentrations of As, Cd, Cu, and Hg in the small part samples of the west plain and central areas are higher than the national second-grade quality standard, indicating some level of contamination. Multivariate and geostatistical methods have been applied to differentiate the influences of natural processes and human activities on the concentration of heavy metals in surface soils in the study area. Cluster and factor analyses result in the grouping of Al, As, Cr, Cu, Fe, Ni, and Si into factor F1; Co, Mn, Pb, and Zn into F2; and Cd and Hg into F3. The spatial pattern of the three factors may be well demonstrated by geostatistical analysis. It is shown that the first factor could be considered as a natural source controlled by parent material. The second factor could be referred to as “industrial and traffic pollution sources”. The source of the third factor is mainly controlled by long-term anthropic activities, including agricultural activities, fossil fuel consumption, and atmospheric deposition.",

"abstract": "Spatial variability and distribution of Cr contents in agricultural soils of Dongguan city, Guangdong Province are studied using geo- statistics and geographic information system(GIS)techniques. 118 surface samples and 5 vertical sections of agricultural soil were collected from Dongguan city. Spatial structure is described with Variogram. The results show that Cr contents are 2.28～94.98 mg·kg-1 in agricultural soils of Dongguan, the mean content is 44.90 mg·kg-1, and higher slightly than the soil background value of Dongguan. Well-defined struc- ture with nonzero nugget effect, distinct sill and range can be fitted with exponential model (R2=0.78, P<0.01), which is mostly influenced by soil parent materials and landform, the relative range is 18.3 km. Variogram analysis shows that spatial structure of Cr contents has obvious geometric anisotropy whose ratio is 1.8. The major axis is in northwestern 13° direction in which there is the longest range. The spatial distri- bution of Cr contents shows that Cr contents of agricultural soils are high in west and low in east, which is mostly controlled by soil parent ma- terials and landform, is influenced strongly by anthropogenic factors.",

"abstract": "In order to find out the distribution characteristics of organochlorine pesticides in groundwater in the Pearl River Delta, 10 groups of groundwater samples from the Pearl River Delta region were tested with gas chromatography.The result shows there are varieties of organochlorine pesticides existing and widely distributing in groundwater of the Pearl River Delta Region, but their concentration is generally low.On the whole, as far as distribution range is concerned, pollutants of HCHs kind are the widest, next are other pollutants(pollutants other than HCHs and DDTs in this paper), pollutants of DDTs kind are the smallest.As far as concentration is concerned, other pollutants are the highest, next is HCHs kind, DDTs kind is the lowest.In addition, by comparing organochlorine pesticides in groundwater of Suzhou, Wuxi and Changzhou to that of Bangladesh in 1995, the conclusion is achieved:an early ban of organochlorine pesticides is one of the important factors leading to the low concentration of organochlorine pesticides in groundwater of the Pearl River Delta region.Altogether, although organochlorine pesticides pollution is not severe in groundwater in Pearl River Delta region, given organochlorine pollutants' difficult degradation and that its harm could be magnified by gradual accumulation in organism, attention must be paid to pollution trend of organochlorine pesticides, the area severely polluted must be protected and managed.",

"abstract": "Fluorine contents were determined in 46 vegetables and 8 paddies, and most of them in the vegetables did not exceed the national hygienic standard(1.0 mg·kg-1). The accumulation of fluorine showed great differences among different vegetable types, and mustard had the highest fluorine concentration in all vegetables determined. But all paddies determined exceeded the national hygienic standard seriously, with the average and highest fluorine content was 22.85 mg·kg-1 and 31 mg·kg-1 respectively. Fluorine concentrations in 115 soil samples were determined, and 46% exceeded the national standard. The water-soluble fluorine content varied with the soil characters, and led to high fluorine content in paddies and low fluorine content in vegetables. And fluorine concentration in all 22 irrigated water samples determined were 0.17~0.68 mg·kg-1, and did not exceed 2.0 mg·kg-1 of the national irrigated water standard. Combined with some scholar′s study that fluorine content in drinking water did not exceed the national hygienic standard, it was found that there were some relations between high fluorine content in paddies and epidemic fluorosis.",

Joining strength, joint microstructure, stress state of joining interface, and diffusion between joined compositions were studied. Experimental results show that a transition interlayer containing both joined particles is formed in the joint which is dense and pore free, fracture taken place at Al_2O_3 matrix near the joining interface but the joining strength is lower than normal Al_2O_3 matrix because of the complex stress state near the interface. Apart from the effect of plasticity of green bulk on joining before sintering, it is postulated from the HRTEM/EDS studied results that the diffusion of Al 3+ to the ZrO_2 grain during the sintering process contributed to the interface bonding which led a success joining of Al_2O_3 and ZrO_2 composites.",

The source material used in the geopolymer concrete was activated with sodium hydroxide and sodium silicate solution. The results revealed that the geopolymer produced with wet bottom boiler fly ash(CZ-FA)hardened quickly, and had higher early-age strength and lower shrinkage than the geopolymer produced with dry bottom boiler fly ash(SX-FA). The compressive strength of the two geopolymers made from CZ-FA and SX-FA was 45 MPa and 15 MPa respectively when cured at 60 °C and delayed for 14 d. However, after 90 days’ delay, the compressive strength of both the samples is almost the same, up to 80 MPa. Nearly 20% volume shrinkage of the samples made from SX-FA was much higher than that made from CZ-FA, which was almost zero. XRD, SEM/EDS and FT-IR were used to analyze the main reason of the differences.",

"abstract": "Abstract In this study, two kinds of alumina based fibrous ceramics, conventional alumina fibrous ceramics and the designed alumina/silica composite fibrous ceramic, were fabricated with different high temperature binders and the effect of the kind of high temperature binder and the binder content on the sample properties were analyzed. Furthermore, comparative analyses of the microstructure and compression and rebound properties of two kinds of alumina based fibrous ceramics were conducted. Conventional alumina fibrous ceramics were fabricated with the silica sol as the high temperature binder and the introduction of silica sol endow the sample a high compressive strength; however, the introduced silica phase would fill the pores constructed by the alumina fibers, consequently increasing the sample porosity. The alumina/silica composite fibrous ceramics were fabricated with glass fibers as the high temperature binder. The alumina fibers lapped with each other and acted as the main matrix of structure, while the molten silica binders bonded the junction of matrix fibers. Therefore, the high temperature binder would not influence the sample porous structure. The alumina/silica composite fibrous ceramic exhibited a higher compression and rebound ratio than the alumina fibrous ceramic due to its excellent skeletal structure.",

During the preparation process, silica sol, Al(NO 3 ) 3 solution and NH 4 F solution were introduced into the fibrous brick in the form of ions or sol through vacuum impregnation and freeze drying, and the silica sol, Al(NO 3 ) 3 and NH 4 F served as the silica sources, aluminum source and catalyst, respectively. Effects of process parameters (concentration of impregnation solutions, holding time, sintering temperature) on compressive strength and elastic modulus of the fibrous brick during the in situ toughening process were analyzed. SEM and XRD analysis results demonstrated that the mullite whiskers were synthesized on the surface of mullite fibers based on the reaction of AlOF and SiF 4 . What is more, the whiskers on adjacent fibers intersected with each other and formed many unfixed lap-jointing points, resulting in the increase of compressive strength and elastic modulus. Although the density and thermal conductivity of the sample after the generation of mullite whiskers fabricated with the optimum process were 0.406 g/cm 3 and 0.1262 W/(m K), respectively, which were slightly higher than that of the raw fibrous brick (0.375 g/cm 3 density and 0.1069 W/(m K) thermal conductivity, respectively), the corresponding compressive strength and elastic modulus of the sample reinforced with the whiskers increased to 1.45 MPa and 42.03 MPa, respectively, which were much higher than that of the raw fibrous brick (0.39 MPa compressive strength and 6.5 MPa elastic modulus).",

In addition, the electrochemical performance was enhanced with the increasing Mo content. However, more aggregation of particles was found to occur at a higher Mo content, which resulted in worse electrochemical performance.

"abstract": "Abstract High-emissivity MoSi 2 -SiC-Al 2 O 3 -SiO 2 coating with MoSi 2 and SiC as emittance agents, Al 2 O 3 as base skeleton, and silica sol as both dispersive medium of the coating slurry and binder of the coating, was prepared on mullite fibrous insulations via slurry coating and non-firing process. The non-firing coatings were calcined at high temperatures to reveal their reusability after high temperature service. Microstructure, phase composition, interface bonding strength and impact resistance of the non-firing coating and the calcined coatings were investigated comprehensively. Thermal shock resistance, thermal endurance and infrared radiation property of the coatings were studied. The results show that the non-firing coating was dense and flat with all particles bonded together by silica sol; no clear interface existed between the coating and the substrate due to the penetration of the coating slurry; the whole coating was composed of a porous inner layer of about 300 µm in thickness and a top layer of about 100 µm in thickness. The calcined coatings exhibited ideal microstructure with newly formed high temperature phases. Both interface bonding strength and impact resistance of the calcined coatings increased with elevated calcination temperatures, benefited from the good binding effect of silica sol, the gradient structure and the formation of mullite. The coatings remained intact without peeling and spalling after thermal shock tests, and the main defects in the coating surface after thermal shock tests at 1400 °C and 1500 °C were cracks and holes, respectively. The coatings exhibited better long-term thermal endurance at 1400 °C than at 1500 °C, resulted from the weaker oxidation of emittance agents at lower temperature. The emissivity of the non-firing coating at the wavelength range of 3–5 µm and 8–12 µm was as high as 0.9, benefited from the non-firing process, and the emissivity of the calcined coatings were higher than 0.8.",

"title": "Microstructure, mechanical properties and thermal shock resistance of ZrO2–LaPO4 composites",
"abstract": "4YSZ–LaPO 4 composites with different LaPO 4 content ranging from 0 to 30 vol.% were prepared. Influence of LaPO 4 content on the microstructure, mechanical properties and thermal shock resistance under mild thermal conditions of the composites were investigated. With the increased content of monazite LaPO 4 , Vickers hardness, flexural strength and fracture toughness of the 4YSZ–LaPO 4 composites exhibited a gradual degradation, while the thermal shock resistance was improved obviously. Results showed that the critical thermal shock temperature (Δ T c ) of 4YSZ/30 vol.% LaPO 4 composite under air quenching was 1400 °C, which was 400 °C higher than that of monolithic 4YSZ. Improvement of thermal shock resistance for 4YSZ–LaPO 4 composites was mainly due to the higher ratio value of K Ic / σ and the crack deflection and bridging at weak bonding interface between ZrO 2 and LaPO 4 . Keywords Ceramics Composites Mechanical properties Microstructure Scanning electron microscopy 1 Introduction Dense zirconia ceramics are materials with important technological applications due to their unique combination of excellent properties, such as strength, toughness, chemical stability, refractory characteristics and corrosion resistance [1–3] . However, the poor thermal shock resistance, resulting from the high thermal expansion coefficient and low thermal conductivity, largely limited their actual applications. Thermal shock resistance is a major issue for ceramics applied under high temperature environment. According to the classic theory on the thermal shock behavior of brittle ceramics established by Hasselman [4,5] , increased thermal shock resistance can be achieved either by making it more difficult for cracks to initiate or by limiting the extent to which they can grow once cracking has started. Obtaining useful improvements to the thermal shock resistance by preventing the initiation of cracks is difficult, particularly when the thermal shock is severe, as the crack driving forces can be many orders of magnitude greater than the resistance to fracture of ceramic materials. It is therefore more usual to try to limit the extent of crack propagation. This requires either that as much energy as possible be dissipated in growing the crack, or that the crack driving force available to each individual crack be reduced. In recent years, some literatures reported that the incorporation of a particulate second phase (e.g., molybdenum [6] , Fe 3 Al [7] , Al 2 TiO 5 [8] , h-BN [9] , AlN [10] and ZrB 2 [11] ) into dense zirconia matrix could lead to an enhanced thermal shock resistance. The improvement of thermal shock resistance was largely attributed to the crack shielding and blunting and crack deflection. While the composites have an improved thermal shock resistance, the usefulness of them is limited by their sensitivity to oxidation. Monazite LaPO 4 is a suitable and effective oxide interface material, which exhibits high stability at high temperature in both reducing and oxidizing environment and shows good chemical compatibility with ZrO 2 [12] . The ZrO 2 /LaPO 4 interface is weak enough to prevent crack growth by interfacial debonding and crack deflection [13] . Therefore, it is expected that the thermal shock resistance can be improved without compromising the excellent refractoriness of zirconia ceramics. In this paper, influence of LaPO 4 content on the thermal shock resistance of dense 4YSZ–LaPO 4 composites under mild thermal condition was investigated. 2 Experimental procedure Commercial available Y 2 O 3 (99%, Zibo rare earth material Co. Ltd., Shandong, China), ZrO 2 (99.5%, 0.5 μm, Fanmeiya powder Co. Ltd., Jiangxi, China) and LaPO 4 (99%, Zibo rare earth material Co. Ltd., Shandong, China) powders were used as the starting materials. The LaPO 4 powder was calcined at 1250 °C for 1 h. The mixtures of ZrO 2 , Y 2 O 3 and LaPO 4 were ball milled for 8 h using nylon pots with high purity zirconia balls, Y 2 O 3 –LaPO 4 ranging from 0 to 30 vol.%. The milled slurry was dried at 100 °C in a baking oven and then sieved through an 80 mesh. The dried powder mixture was uniaxially pressed at 200 MPa into rectangular green compacts (30 mm × 7 mm × 4 mm) and then cold isostatic pressed at 250 MPa. The green samples were pressureless-sintered in air at 1550 °C for 2 h according to our existing preparation conditions. Bulk density of the sintered specimens was measured by the Archimedes displacement method with distilled water, and the theoretical density was estimated by the rule of mixtures. Sintered specimens for flexural strength test were machined into bars with dimensions of 25 mm × 5 mm × 2.5 mm, and the top and bottom surfaces were ground flat and polished by standard diamond polishing techniques down to 1 μm. The edges of all the specimens were chamfered to minimize the effect of stress concentration due to machining flaws. The flexural strength of the specimens was tested using a conventional three point flexural method, with a span of 20 mm and a cross-head speed of 0.368 mm/min. Measurements were performed on at least five test bars of each material. Hardness (Hv) and fracture toughness ( K IC ) at room temperature were determined from Vickers indentation tests (HV-10 Vickers hardness tester) on polished surfaces with indentation loads of 98 and 196 N during times of 15 s, respectively. No chipping associated with any indentation was detected, and the indentations that exhibited secondary radial cracking were rejected. The principal diagonals of the plastically deformed zone and the length of the radial cracks were measured using the optical microscopy equipped on HV-10 Vickers hardness tester. The equation proposed by Niihara [14] was used to calculate the K IC . Reported Hv and K IC values are the average of ten determinations and errors are the standard deviations. The young's modulus and thermal expansion coefficient of ZrO 2 –LaPO 4 composites were calculated by Eq. (1) [15] : (1) E = E 1 V 1 + E 2 V 2 where subscripts 1 and 2 denote ZrO 2 and LaPO 4 , respectively. V is the volume fraction. The microstructures of sintered, polished and fractured specimens (after ultrasonic cleaning with acetone and dried) were examined using a Philips XL-30 scanning electron microscope (SEM). XRD analysis was carried out using Rigaku D/max 2500 v/pc X-ray diffractometer (Cu Kα, Ni filter). The volume fraction of the m -ZrO 2 ( V m ) was calculated by measuring the intensities of (1 1 1) and (−1 1 1) reflections of the monoclinic phase and the (1 0 1) peak of the tetragonal phase according to the formula of Toraya et al. [16] : (2) V m = 1.311 X m 1 + 0.311 X m (3) X m = I m ( 1 1 1 ) + I m ( − 1 1 1 ) I m ( 1 1 1 ) + I m ( − 1 1 1 ) + I t ( 1 0 1 ) where X m denotes the integrated intensity ratio, I m and I t are the peak intensities of the m -ZrO 2 and t -ZrO 2 , respectively. The obtained volume fractions of m -ZrO 2 ( V m ) were individually normalized to the volume fractions of ZrO 2 ( V Zr O 2 ) present in each composite as follows: (4) V m t = V m × V Zr O 2 100 Thermal shock tests were performed by measuring the retained flexural strength after quenching into air from desired temperatures. The bars for thermal shock test were heated to desired temperatures for 20 min in a drop-bottom furnace and then air quenched from elevated temperature to room temperature. Thermal quenching was conducted at 623–1423 °C, which corresponded to thermal shock temperature differences (Δ T ) of 600–1400 °C. At least five samples were tested for each temperature difference. 3 Results and discussion 3.1 Phase composition and microstructure X-ray diffraction patterns in the 2 θ range from 20° to 34° of polished surfaces of the composites with different LaPO 4 content are shown in Fig. 1 . Three phases, monoclinic zirconia, tetragonal zirconia and monazite LaPO 4 were observed and no new phase could be found in the XRD patterns. This result indicated that LaPO 4 did not react with ZrO 2 at 1550 °C. The content of m -ZrO 2 in the composites increased with increasing LaPO 4 content ( Table 1 ). It indicated that more spontaneous martensitic transformation occurred with the increased content of LaPO 4 in the ZrO 2 –LaPO 4 composites during cooling from the sintering temperature. Fig. 2 is the SEM micrographs of fracture surfaces of monolithic ZrO 2 (ZLa0), ZLa15 and ZLa30. It was observed that ZLa30 had a homogeneous grain size (about 1 μm) distribution. But some abnormal grains over 2 μm could be easily found in the SEM images of ZLa0, ZLa15 ceramics. This indicated that LaPO 4 inhibited the abnormal grain growth of ZrO 2 during sintering process. Monolithic ZrO 2 ( Fig. 2 (a)) shows both intergranular and transgranular fractures, but ZrO 2 –LaPO 4 composites showed a higher tendency of intergranular fracture, which increased with increasing LaPO 4 content. 3.2 Mechanical properties The relative density and mechanical properties of ZrO 2 –LaPO 4 composites with different LaPO 4 content are shown in Table 2 . The relative density of all the sintered composites was above 98%, which was closed to the theoretical density and was consistent with the dense microstructure in Fig. 2 . The hardness, flexural strength and Vickers toughness decreased with increasing LaPO 4 content. The decrease of Vickers hardness was directly due to the addition of soft LaPO 4 (Young's modulus of LaPO 4 is ∼100 Gpa). Because of the weak-bonding interfaces between LaPO 4 and ZrO 2 , when samples were fractured, less energy was required with the increased content of LaPO 4 , thus resulting in the decrease of flexural strength. When the composite was fractured, part of t -ZrO 2 would transform to m -ZrO 2 , which is known as the stress-induced phase transformation [17] . If more t -ZrO 2 transformed to m -ZrO 2 during the fabrication, the transformation toughening decreased during fracture. It was shown in Table 1 that the content of m -ZrO 2 increased with increasing LaPO 4 content. In addition, the Young's modulus and fracture energy decreased with increasing LaPO 4 content. Consequently, the toughness of the composites decreased with increasing LaPO 4 content. 3.3 Thermal shock resistance In the Hasselman's theory, the residual strength of material after quenching is an important index to estimate the thermal shock resistance. In the current study, specimens of the ZrO 2 –LaPO 4 composites were subjected to a range of temperature differentials by air quenching. The retained flexural strength was then measured in the same way as in Section 2 . The residual strength of ZrO 2 –LaPO 4 composites as a function of thermal shock temperature is shown in Fig. 3 . It was shown that the critical thermal shock temperature (Δ T c ) of ZLa0 and ZLa10 were 1000 °C, indicating that the thermal shock resistance of ZrO 2 was not improved remarkably by adding 10 vol.% LaPO 4 . The Δ T c of ZLa15 was 1200 °C, which was almost the same to that of ZLa20. In the experiment, the highest Δ T c (about 1400 °C) was obtained by ZLa30 composites. The conditions for crack initiation and propagation in ceramics had been extensively analyzed by Hasselman [2] . The condition for stable and unstable crack growth were predicted based on the idea that the driving force for crack propagation was provided by the stored elastic strain energy. A number of thermal shock parameters ( R parameters) were defined to relate thermo-physical and thermo-mechanical properties of the materials to their thermal shock resistance. The effect of microstructure on thermal shock behavior of ZrO 2 –LaPO 4 composite could be demonstrated by using the parameters: (5) R ′ = k σ ( 1 − ν ) E α (6) R IV = K Ic 2 σ 2 ( 1 − ν ) where k is thermal conductivity, σ is the strength, E is the Young's modulus, α is the thermal expansion coefficient, and ν is the Poisson ratio. The R ′ parameter provided a measure of the resistance to crack initiation, while the resistance to crack propagation could be gauged from the R IV parameter. Higher value of R ′ and R IV predicated a higher thermal shock resistance. Because the thermal conductivity and the thermal expansion coefficient of ZrO 2 was very close to those of LaPO 4 [18] , and the Poisson ratio was almost a fixed value for ZrO 2 –LaPO 4 composites, the value size of R ′ and R IV could be determined by σ / E and K Ic / σ , respectively. The calculated value of σ / E and K Ic / σ for ZrO 2 –LaPO 4 composites were also listed in Table 2 . The calculated σ / E value decreased with increasing LaPO 4 content, implying that a decreasing critical temperature differential would be expected. This was opposite to the experimental result in Fig. 3 . It was possible that micro-cracks in the composites did indeed initiated for a relatively low Δ T , but that the high damage resistance of the composites resulted in minimal crack propagation and consequent strength degradation. Such a claim was also supported by the calculated value of K Ic / σ , which was increased with increasing LaPO 4 content. The results of the SEM and energy spectrum indicated that the weak interfaces between ZrO 2 and LaPO 4 particles and the layered structure of LaPO 4 played the very important role in resisting the propagation of thermal shock induced micro-cracks. The evidence was shown in Fig. 4 . It could be observed that the thermal shock induced crack was discontinuous and propagated along the interfaces between LaPO 4 and ZrO 2 . The crack deflection and divergence would lead to a partial relief of the thermoelastic strain energy and hence, contributed to resistance to crack propagation. Moreover, the increasing phase transformation of zirconia in ZrO 2 –LaPO 4 composites would contribute to the resistance to crack propagation ( Table 1 ). Consequently, stable crack propagation was possible during air quenching, thus minimizing the strength degradation as demonstrated in the strength versus air quenching temperature response of the ZrO 2 –LaPO 4 composite ( Fig. 3 ). 4 Conclusions 4YSZ–LaPO 4 composites with different LaPO 4 content ranging from 0 to 30 vol.% were prepared. Microstructure, mechanical properties and several parameters relevant to the thermal shock resistance including critical temperature differential, R ′ and R IV were evaluated and discussed. With the increased content of LaPO 4 , the Vickers hardness, flexural strength and toughness of the composites decreased gradually, but the thermal shock resistance was improved obviously. The critical temperature differential of thermal shock resistance for the ZLa30 composite was found to be higher than for monolithic 4YSZ (ZLa0) experimentally as much as 400 °C. Higher ratio value of K Ic / σ and the crack deflection at weak bonding interface between ZrO 2 and LaPO 4 were the main factors to improve the thermal shock resistance of the 4YSZ–LaPO 4 composites.

"abstract": "Abstract High emissivity coatings on fibrous insulation tiles played an important role in thermal protection systems and thereby intrigued many researchers; however, there was little emphasis on the mechanical properties of the coatings. In this study, a gradient MoSi 2 -borosilicate glass coating with a dense surface layer and a porous interlayer was designed for mullite fibrous ceramics. Mechanical properties and structure parameters of the coating layers and the substrate were studied. The gradient coating was compared with a monolayer dense coating of the same composition and same surface density in contact damage resistance, impact resistance and emissivity. Compared with monolayer dense coating coated substrates, the gradient coating coated ones exhibited two times higher load bearing capacity in Hertzian indentation test at the same displacement of 1 mm; they appeared to be stiffer and harder at constant load of 20 N, and showed better impact resistance at impact energy range of 0.25–0.75 J in the falling weight test; besides, fatal radial cracks were not observed in gradient coatings after the tests. In addition, the gradient coating had higher emissivity (0.838) than the monolayer dense coating (0.816) because of the significant absorptivity increase and reflectivity decrease by small gradual slopes in the rough surface.",

"abstract": "Porous Y2SiO5 ceramics with relative high compressive strength (as high as 24.45 MPa) and ultra-low thermal conductivity (∼0.08 W/m K) were successfully fabricated by a tert-butyl alcohol based gel-casting method. The formation mechanism of the 3D interconnected pores and the properties of the green body are discussed. The porosity, pore size, compressive strength and thermal conductivity could be controlled by varying the initial solid loading and the sintering temperature. When regulating the initial solid loading (from 20 to 50 wt%) and sintering temperature (from 1200 to 1500 °C), the porosity can be controlled between 47.74% and 73.93%, and the compressive strength and the thermal conductivity of porous Y 2SiO5 ceramics varied from 3.34 to 24.45 MPa and from 0.08 to 0.55 W/m K, respectively. It should be noted that the porous Y 2SiO5 ceramics with 30 wt% solid loading and sintering at 1400 °C had an open porosity of 61.80%, a pore size of 2.24 μm, a low room-temperature thermal conductivity of 0.17 W/m K and a relatively high compressive strength of 13.91 MPa, which make this porous Y2SiO 5 ceramics suitable for applications in high-temperature thermal insulators. © 2012 Elsevier Ltd and Techna Group S.r.l.",

"abstract": "Effects of fly ash cenospheres on the microstructure and properties of silica-based composites were studied in this paper. It was found that the density of the samples decreased as the content of fly ash cenospheres increased, while the strength increased inversely when the content was lower than 50 wt%. An interlaced microstructure of lath-like and needle-like mullite crystals was discovered in the composites, which was a beneficial factor for strengthening the silica matrix. Furthermore, the results indicated that fly ash cenospheres can promote the densification of silica as a sintering aid and restrain the crystallization of cristobalite as an inhibitor. After sintered at 1200°C for 2 h, the density and flexural strength of silica-based composites with 50 wt% fly ash cenospheres were 0.92 g/cm 3 and 14.5 MPa separately, and the strength was as high as that of the silica ceramics without fly ash cenospheres. © 2012 Elsevier Ltd and Techna Group S.r.l.

The whole self-assemble process, the function of surfactant and the effect of TiO_2 slurry′s concentration to the self-assemble were discussed.

"title": "Molten salt synthesis of mullite whiskers from various alumina precursors",
"abstract": "Different reaction processes were observed in the preparation of mullite whiskers by molten salt synthesis (MSS) when Al 2 (SO 4 ) 3 and Al(OH) 3 used as alumina precursors. It was found that amorphous Al 2 O 3 from Al 2 (SO 4 ) 3 reacted with silica to form mullite in Na 2 SO 4 flux at 900–1100 °C, whereas γ-Al 2 O 3 from Al(OH) 3 did not participate the synthesis reaction of mullite. The formation of tiny-sized amorphous Al 2 O 3 resulted from both free Al-cations in liquid and amorphous silica by means of Al 2 (SO 4 ) 3 . In addition, mullite with 67 mol% Al 2 O 3 formed in 1/1, 2/1 and 3/1 mixtures while mullite with 72 mol% Al 2 O 3 formed in 4/1 mixture, when powder mixtures [Al 2 (SO 4 ) 3 as alumina precursor] with Al/Si atomic ratios of 1/1, 2/1, 3/1 and 4/1 were used. The formation of Al-rich mullite was ascribed to the low synthesizing temperature by MSS. Keywords Ceramics Crystal growth Anisotropy Scanning electron microscopy X-ray diffraction 1 Introduction Mullite is a kind of superior engineering materials due to their excellent mechanical property and especially its strength retained up to 1300 °C [1,2] . So it is an important component in composite [3] , porous [4] and membranous [5,6] ceramics. However, various processing routes have been reported for the preparation of mullite powders such as sol–gel precursors [7,8] , thermal decomposition of minerals [9] , rare earth oxide doping [10,11] and internal crystallization method [12] , developing new approaches to prepare mullite whiskers in controlled morphology still remains a challenge. As a new ceramic powder synthesis method, molten salt synthesis (MSS) has been employed to synthesize ceramic powders because it decreases reaction temperature and gives powders of homogeneous morphology [13,14] . Al 2 (SO 4 ) 3 was used as alumina precursor to form mullite via 3Al 2 O 3 + 2SiO 2 = Al 6 Si 2 O 13 in molten alkali-metal sulfates [15] . Ouatib concluded that γ-Al 2 O 3 ( F d 3 ¯ m ) formed from the decomposition of Al 2 (SO 4 ) 3 and then reacted with silica to form mullite [16] , but there was no specific demonstration. At the same time, the formation of amorphous Al 2 O 3 by the decomposition of Al 2 (SO 4 ) 3 in molten sodium sulfate was observed [17] . Thus, it was necessary to investigate the reaction process to form mullite via MSS. In this work, together with Al 2 (SO 4 ) 3 , Al(OH) 3 were used as another alumina precursor to study the reaction process owing to its low decomposition temperature [18] . Besides the sort of starting materials, Al/Si ratio of starting materials is another factor that has a significant effect on the composition and morphology of mullite [19] . In mullite whiskers synthesized by solid-state reaction [20,21] , Si-rich composition was suggested to facilitate the growth of anisotropic mullite that contained low Al 2 O 3 content (i.e. <60 mol% Al 2 O 3 ). In comparison with traditional solid-state reaction, MSS has several advantages, such as low processing temperature, better control of composition, high homogeneity and purity as well as a liquid environment. Thus, the relationship between the composition and morphology of mullite and the Al/Si ratio of starting materials in MSS may be different from that for solid-state reaction synthesis. To the best of our knowledge, there has been scarce report on the successful synthesis of mullite whiskers via MSS. In present study, reaction processes in MSS with different alumina precursors were reported. The composition and morphology of mullite prepared by firing powder mixture with various Al/Si ratios were investigated. 2 Experimental procedures As raw materials, aluminum sulfate [Al 2 (SO 4 ) 3 ] (>99% purity), aluminum hydroxide [Al(OH) 3 ] (>99% purity), amorphous silica (>99% purity, 25 μm in size) and sodium sulfate (Na 2 SO 4 , mp = 884 °C [22] ) (>99% purity) (Jiangtian Chemical Co., Tianjin, China) were used. Powder mixtures were ball-milled for 4 h and then fired in alumina crucibles at a heating rate of 300 °C/h. The compositions and firing conditions of all power mixtures are shown in Table 1 . The prepared samples were washed with 95 °C water to remove the sulfate. Finally, white powders were obtained after drying at 80 °C for 24 h. Crystalline phase and morphology of the powders were examined by X-ray diffraction (XRD, D/MAX 2500 Rigaku) and scanning electronic microscope (SEM, XL-30 Philips), respectively. Element contents were detected by using EDS attached to the SEM. In order to explain different reaction processes with various alumina precursors, differential thermal analysis (DTA) and thermo gravimetric analysis (TG) were performed up to 1200 °C at a heating rate of 10 °C/min in air. 3 Results and discussion 3.1 Effect of alumina source on mullite formation Fig. 1 shows XRD patterns of the products obtained by firing powder mixtures with various alumina precursors (S 12 and S 22 ) at 900–1100 °C for 3 h. It was found that mullite was the main crystalline phase in S 12 ( Fig. 1 a). With temperature increasing to 1000 °C, the line width decreased while intensity of the diffraction line increased, demonstrating an improvement in crystallinity and an increase in the amount of mullite. Residual amorphous silica was gradually transformed to cristobalite above 1000 °C. α-Al 2 O 3 in S 12 appeared at 1000 °C, while there was no crystal Al 2 O 3 at 900 °C. On the other hand, Lazurite [Na 8.16 (Al 6 Si 6 O 24 )(SO 4 ) 1.14 S 0.86 ] was detected in S 22 ( Fig. 1 b). Fig. 2 shows morphology of the products obtained by firing S 12 and S 22 at 1000 °C for 3 h. Mullite whiskers were observed in S 12 ( Fig. 2 a) while irregularly shaped Lazurite was observed in S 22 ( Fig. 2 b). Fig. 3 shows XRD patterns of the products obtained by firing S 12 and S 22 at 900 °C without heat preservation. The consistent diffraction peak at 14–25° in both XRD patterns resulted from amorphous SiO 2 . γ-Al 2 O 3 formed by the decomposition of Al(OH) 3 was detected in S 22 while no peak of crystal Al 2 O 3 was detected in S 12 . It suggested that the Al 2 O 3 formed in S 12 might be in an amorphous state. The conclusion was further validated by EDS analysis that it contained 46.75% Al and 53.25% Si (atomic ratio). Fig. 4 a shows DTA curves of S 12 and S 22 . When S 12 was fired, a liquid phase of Al 2 (SO 4 ) 3 –Na 2 SO 4 due to the low-melting point, formed at approximate 640 °C [23] , resulting in endothermic peak (a) in the DTA curve. According to previous reports [24,25] , exothermic peak (b) was caused by the formation of mullite at approximate 900 °C. As shown in Fig. 4 b, the remarkable weight loss indicated in TG curve of S 12 , was due to the decomposition of Al 2 (SO 4 ) 3 above 700 °C [11] . In DTA curve of S 22 , endothermic peak (c) was thought to be caused by the decomposition of Al(OH) 3 at about 300 °C [14] . Another endothermic peak (d) after 880 °C (close to the melting point of Na 2 SO 4 ) was due to the formation of Na 2 SO 4 liquid. At higher temperature, the formation of Lazurite caused exothermic peak (e). The DTA and TG results indicated that the reaction processes in S 12 and S 22 were different. The reaction order (1) in S 12 is as follows: the formation of a liquid, the decomposition of alumina precursor and the formation of mullite. On the other hand, the reaction (2) in S 22 is in the order of the decomposition of alumina precursor, the formation of a liquid and the formation of product. As is well known, free cations and anions formed when electrolyte is fired above melting point. According to this principle, free Al-cations firstly formed in liquid before decomposition of Al 2 (SO 4 ) 3 followed reaction process (1), and then they transformed to tiny-sized amorphous Al 2 O 3 above 700 °C. It was found that amorphous silica retarded the polymorph transformation of Al 2 O 3 by preventing particles from coming into contact and suppressing nucleation on the Al 2 O 3 surface in former research [26] . In this case, the crystallization and growth of amorphous Al 2 O 3 were prevented by amorphous silica. The co-existence of free Al-cations in liquid and amorphous silica resulted in the formation of tiny-sized amorphous Al 2 O 3 with high reactivity. It explained the phenomenon that there was no characteristic peak of crystal Al 2 O 3 detected in XRD pattern of S 12 after the decomposition of alumina precursor, as shown in Fig. 3 . Amorphous silica reacted with amorphous Al 2 O 3 to form mullite, which precipitated from liquid as final product. On the other hand, when firing S 22 , γ-Al 2 O 3 firstly formed by the decomposition of Al(OH) 3 . Compared with amorphous Al 2 O 3 with high reactivity, γ-Al 2 O 3 cannot form mullite at low temperature. Instead, it reacted with amorphous silica and molten Na 2 SO 4 to form Lazurite that is scarcely reported before. The observed result is not in agreement with Ouatib's conclusion [16] . It can be concluded that amorphous Al 2 O 3 is beneficial for the formation of mullite in MSS. 3.2 Characterization of whiskers: effect of Al/Si on composition and morphology of mullite The dependence of cell dimensions on Al/Si ratios has been well investigated a and c increase, and b decreases with increasing Al/Si ratios, resulting in the transformation of mullite from the orthorhombic ( a = 0.76 nm, b = 0.77 nm, and c = 0.29 nm) to the tetragonal ( a = b ) [27] . Thus, Al/Si ratio in mullite can be reflected by the 120 and 210 peaks, which are split in orthorhombic and overlapped in tetragonal. Fig. 5 shows angular separation of the 120 and 210 peaks of mullite prepared by firing powder mixtures with 1/1, 2/1, 3/1 and 4/1 (Al/Si, atomic ratios), which were named as S 11 , S 12 , S 13 , and S 14 , respectively ( Table 1 ). The 120 and 210 peaks moved closer together in S 14 , while there was no change in the position of the 120 and 210 peaks in S 11 , S 12 and S 13 . It was concluded that Al 2 O 3 contents in mullite derived from Al-deficient S 11 and S 12 and stoichiometric S 13 compositions are very close. On the other hand, the changing of angular separation of the 120 and 210 peaks indicated that mullite prepared with S 14 contained higher Al 2 O 3 content. Fig. 6 shows SEM of the powder mixtures with various Al/Si fired at 1000 °C for 3 h, etched with 20 wt% HF for 20 min at room temperature. The EDS spectrum taken from the whiskers showed the compositions of mullite prepared with various Al/Si ratios. Anisotropic mullite was observed in all four samples, which contained approximate 67 mol% Al 2 O 3 for S 11 , S 12 and S 13 and approximate 72 mol% Al 2 O 3 for S 14 . In a conclusion, mullite whiskers prepared by firing powder mixtures with Al-rich compositions contained higher Al 2 O 3 content than those with Al-deficient and stoichiometric compositions. The EDS analysis was in good agreement with the XRD result. In previous research, anisotropic grains were observed in Al-deficient mullite prepared by solid-state method [20,21] . However, anisotropic grains were observed in Al-rich mullite by MSS. The difference was ascribed to the liquid environment provided by molten flux which facilitates the growth of anisotropic mullite. Another interesting phenomenon was that Al-deficient and stoichiometric mullite did not form, regardless of the Al/Si = 1/1, 2/1 or 3/1, molar ratio of the powder mixtures. Okada et al. [28] reported that the Al-rich mullite synthesized at lower temperatures corresponded to primary mullite (tetragonal-like), and those synthesized at higher temperatures corresponded to ordinary mullite (orthorhombic mullite). According to this principle, the formation of Al-rich mullite was ascribed to the low synthesizing temperature by MSS. In addition, the same phenomenon was observed when mullite whiskers were synthesized below 1100 °C by a vapor–solid reaction [29] . 4 Conclusions Different reaction processes were studied when firing powder mixtures with Al 2 (SO 4 ) 3 and Al(OH) 3 as alumina precursors. Amorphous Al 2 O 3 is beneficial for the formation of mullite by MSS. Anisotropic grains were formed in Al-rich mullite by MSS. The mullite whiskers prepared with 1/1, 2/1 and 3/1 powder mixtures contained about 67 mol% Al 2 O 3 , while those prepared with 4/1 powder mixture contained about 72 mol% Al 2 O 3 . The formation of Al-rich mullite was ascribed to the low synthesizing temperature by MSS.

"abstract": "Abstract It has been proved that the secondary structure assembled on each fiber in the porous fiber network can catch the ultrafine particles easily in filtration process. In this work, three different networks without (naked fiber) or with different secondary structure (mullite whisker/mullite fiber or corundum plate/mullite fiber) were prepared to investigate the influence of secondary structure on the high temperature mechanical property and the soot oxidation. The mullite whisker/mullite fiber (MW/MF) network exhibited the best high temperature compress resistence and lowest soot oxidation temperature. The soot oxidation start temperatures were 434 °C and 443 °C in the mullite whisker/mullite fiber (MW/MF) and corundum plate/mullite fiber (CP/MF) webs respectively, which was lower than that in the Naked mullite fiber (MF) web (473 °C). Thus, fiber webs assembled with secondary structures have been shown to be promising filter with effective soot oxidation activity.",

The obtained sample was characterized by chemisorption, X-ray powder diffraction (XRD) and transmission electron microscopy (TEM) equipped with an energy dispersion X-ray spectrometer (EDX). XRD and EDX analyses confirmed that Rh ions were reduced into metallic Rh during the plasma reduction. TEM analysis revealed that the argon plasma reduction induces a high dispersion of Rh nano-particles. The average particle size of Rh is 1.2 nm, estimated by chemisorption. For the CO2 reforming of methane, the plasma reduced Rh/Al2O 3 shows comparable activity to a conventional hydrogen reduced catalyst. The value of the standard electrode potential can be employed for the assessment of reducibility of metal ions. The catalyst reduction using argon glow discharge plasma at room temperature will provide a promising alternative to hydrogen reduction for catalyst preparation. © The Royal Society of Chemistry.",

This highly oriented morphology results in the anisotropy in mechanical properties both parallel and perpendicular to freezing direction. In this research, fiber-enhanced ice-templated porous ceramics were fabricated by introducing fibers into alumina slurry for freezing. The trans-lamellar fiber bridges connecting adjacent ceramic walls were formed by adjusting the aspect ratio of fibers and freezing velocity, which greatly enhanced the compressive response in two directions and weakened the anisotropy in mechanical properties of the directional ice-templated ceramics. The results showed that the of fiber bridges increased with the increase of fiber aspect ratio and the longitudinal and transverse mechanical properties increased by 73.5% and 232.6%, respectively.",

"abstract": "Single-phase, near-stoichiometry and well-dispersed chalcopyrite CuInSe 2 nanocrystals were synthesized by a facile, ambient pressure solution chemical route using triethylene glycol as solvent, copper(II) chloride, indium(III) chloride and selenium powder as precursors. Crystallization, morphology, chemical stoichiometry and light property of the synthesized nanocrystals were characterized. Size dependence of the nanocrystals on different alkaline conditions, respectively adding sodium hydroxide, triethanolamine and ethylenediamine into reaction solutions was investigated. The synthesized nanocrystals were used to prepare ethanol-based colloidal inks and then deposit flat, dense and (112) oriented chalcopyrite thin films by layer-by-layer ink-dip-coating method and annealing at 550 °C in Ar. I-V characteristics of the PV devices with the ink-coated CuInSe 2 light-absorbing layer were measured. © 2012 Elsevier B.V. All rights reserved.",

"title": "Development of a buoyancy material of hollow glass microspheres/SiO2 for high-temperature application",
"abstract": "Abstract A type of buoyancy material with excellent temperature resistance was successfully prepared through a molding method, and the hollow glass microspheres (HGMs) and silicon oxide (SiO 2 ) were used as the filler and the matrix, respectively. The effect of sintering temperature on mechanical performance, microstructure, and high-temperature performance of the HGMs/SiO 2 composite were investigated in the study. The HGMs/SiO 2 composite exhibited low density (0.47–0.53 g/cm 3 ), high porosity (66.7–75.6%), low thermal conductivity (0.18–0.27 W/(m·K)), and relatively high compressive strength (3.8–5.2 MPa) properties. The values of Weibull moduli m used to predict the variation degree of compressive strength during the compression process was in the range of 5–15 and its values for the samples sintered at 850 °C was 14.64. Two stages namely elastic stage and fracture stage were shown in the stress-strain curves and in the elastic stage, the stress increased linearly with increasing of the strain until reaching the maximum stress. In the fracture stage, the sample gradually destroyed with further increasing of the strain until complete failure. The compressive strength of the HGMs/SiO 2 composites tested at high-temperature was larger than that of the one tested at room temperature. The HGMs/SiO 2 composite exhibited low density, low thermal conductivity and excellent temperature resistance properties and can be used as the structural material or buoyancy material in the deep sea field in the near future.",

Based on the evaporating of tert-butyl alcohol (TBA) during the drying process, the microstructure with bi-modal pores was obtained. By setting the solid loading (15 wt.%) and changing the sintering temperature from 1050 to 1150 °C, the porosity of the porous silica ceramics varied within the range of 70.1% and 72.4%, as the bulk density varied from 0.59 to 0.67 g/cm 3 and small pore sizes from 3.31 to 2.89 nm. The compressive strength of sintered silica ceramics increased from 4.38 MPa to 5.82 MPa, which was attributed to the 3D-framework structure and the connection of silica particles. © 2011 Elsevier Ltd and Techna Group S.r.l.

"abstract": "Abstract The hierarchical network was prepared by firing the mixture of mullite fiber and a kind of active powder which was made up of alumina gel, silica gel and AlF 3 powder. During which, the smooth surface of mullite fiber was coated with the secondary structure which was controllable by adjusting the firing temperature or by changing the mass ratio of active powder/mullite fiber. The secondary structure created new pore size distribution for the network. Some new pores with diameters of about 1 μm were found in the modified network, while the network constructed by the smooth mullite fiber only had pores with diameters of about 50 μm. Because of the introduction of the secondary structure, the particle filtration efficiency of the network substantially increased. The filtration efficiency for the 0.5 μm particles increased from 12.9% to 94.2%. The filtration efficiency for the 0.3 μm particles also increased from 0.6% to 56.6%.",

In present work, fine grained Al 2 O 3 –ZrO 2 (Y 2 O 3 ) ceramics were obtained through controlled crystallization of dense amorphous bulks by heat treatment. Phase composition, microstructure and mechanical property were investigated during heat treatment. Crystallization and densification were almost completed after heat treatment at 1400 °C for 2 h with relative density of 98.5%, and as-prepared sample exhibited homogenous mixture of Al 2 O 3 and ZrO 2 grains at about 440 nm. The fine grained ceramic exhibited high hardness of 15.5 GPa and fracture toughness of 5.2 MPa m 1/2 . This work may provide new guidance for preparing AZY nanoceramics through crystallization of amorphous phase in both experiment and theory.",

"abstract": "Abstract High emissivity coating is an important part of spacecraft thermal protection system. MoSi2-borosilicate glass coatings prepared by the in-situ reaction method showed excellent thermal endurance and oxidation resistance. However, radial cracks were prone to appear under external forces due to high cohesive of in-situ reaction dense coatings, and few studies focused on the mechanical properties of gradient coatings. In this study, a double-layer gradient MoSi2-borosilicate glass coating with a porous interface layer and a dense surface layer was prepared on mullite fibrous insulation tiles by in-situ reaction method. The double-layer gradient coating was compared with a mono-layer dense coating and a high-density gradient coating (another gradient coating with higher interface layer density) with reference to microstructure, contact damage resistance, interface bonding strength and thermal shock resistance. Compared with mono-layer dense coating and high-density gradient coating, double-layer gradient coating showed higher bearing capacity and avoided radial crack initiation and propagation in Hertzian indentation test. Besides, the double-layer gradient coating endured the most thermal shock cycles between 1500 °C and 20 °C and presented substrate fracture instead of interface fracture. In addition, double-layer gradient coating and high-density gradient coating possessed much higher interface bonding strengths than mono-layer dense coating. The total emissivities of three coatings were all greater than 0.87. The porous interface in double-layer gradient coating presented the advantages in enhanced mechanical and thermal compatibility between the in-situ reaction dense coating and substrate through reducing elastic modulus and thermal expansion coefficient differences.",

"abstract": "In this work, four organoalkali-assisted diethylene glycol solution chemical syntheses, using triethylenetetramine, ethanediamine, N,N-dimethylformamide and triethanolamine as assisting agents, CuCl 2·2H2O, InCl3·4H2O, GaCl3 and Se powder as precursors, N2H4· H2O as the reductant and polyvinylpyrrolidone as the dispersant, were applied to prepare ternary and quaternary chalcopyrite CuIn 1-xGaxSe2 nanocrystals (0 ≤ x ≤ 1). The synthesized products were characterized by XRD, TEM, FESEM, EDX, ICP-MS, Raman, and UV-vis-IR measurements. The dynamic concentrations of fed solutions with reaction time were qualitatively described under non-organoalkali-assisted and organoalkali-assisted conditions. The organoalkali-assisted effects were discussed according to the different alkaline intensity and chelating ability to the monomer precursor species. Chemical stoichiometry control and band-gap tuning of the synthesized ternary and quaternary chalcopyrite CuIn 1-xGaxSe2 nanocrystals were investigated by simply changing In/Ga atomic ratios of the fed solutions in the diethylene glycol based solution process with the optimized triethylenetetramine-assisted amounts. The results showed that the triethylenetetramine-assisted diethylene glycol solution synthesis was a facile and effective way to control the chemical stoichiometry and band-gap energies for single-phase, well-dispersed, near-granular shaped CuIn1-xGaxSe2 nanocrystals with a size range of 10 nm-20 nm.

"title": "Evaluation of metastable degree in amorphous Al2O3-ZrO2-Y2O3 and its effect on plastic deformation",
"abstract": "Abstract Novel plastic deformation was exhibited in amorphous oxides, attributed to the metastable state of amorphous phase with free volume and disordering structure; however, metastable degrees can be quite different in amorphous phases, and the effect of metastability on plastic deformation was never reported in amorphous oxides. In this work, the metastable degree of amorphous phase was controlled by adjusting the temperature in powder calcination, and evaluated through free volume and disordering degree, using the true density of amorphous powder, DSC and 27 Al MAS-NMR. Under compression at 500 °C, the sample with lowest metastability exhibited brittle fracture; however, the other two with higher metastable degrees displayed plastic strain of 3.5% and 5.2%. The enhanced plastic deformation benefited from higher metastability was mainly attributed to easier formation of shear bands. For amorphous phase with higher metastability, the atomic mobility and local free volume were larger, which could improve the formation of shear bands and promote the plasticity according to free volume theory. This work could inspire new methods to improve the plastic deformation in amorphous materials.",

Morphological growth of the CuInSe 2 nanoparticles and nanoplates synthesized respectively with the hydrazine- and ethylenediamine-assisted TEG reaction solution was investigated by XRD, TEM, HRTEM, SAED, XPS and EDX analysis. The results showed that the growth process of CuInSe 2 nanoparticles derived from the hydrazine-assisted solution only underwent quick reduction reaction of elemental Se to Se 2- and cupric Cu 2+ to Cu + to directly form the ternary compound. The growth of CuInSe 2 nanoplates derived from the ethylenediamine-assisted solution involved in the formation of intermediate phase CuSe with lamellar morphology and subsequently a transformation of the CuSe phase into CuInSe 2 phase by gradual reduction of cupric Cu 2+ to cuprous Cu +, In 3+ and active Se 2- participation at growing lattice sites. © 2012 The Royal Society of Chemistry.",

"abstract": "Mesoporous nanocrystalline titania (nc-TiO 2 ) films were synthesized by sol–gel route using poly (alkylene oxide) block copolymer as template and tetrabutyl orthotitanate as titanium source. Influence of acetylacetone (AcAc), glacial acetic acid, HCl and AcAc-HCl as inhibitors on hydrolysis/condensation reaction was investigated. The mesopore structure, crystalline phase and optical characteristics were analyzed by N 2 adsorption, X-ray diffraction, transmission electron microscopy and UV–VIS–NIR spectrum. Photoaction measurements were performed on dye-sensitized solar cells (DSSCs) using the mesoporous nc-TiO 2 as photoanodes. The results show that the formed films are anatase phase and mesoporous structure. Different restraining mechanisms of these inhibitors to hydrolysis/condensation process lead to different mesoporous structure whose specific surface area (S BET ) varies from 34 to 176 m 2 /g, and crystal size is from 5.6 to 38.2 nm. The mesoporous photoanode with high S BET and large crystalline grains may be responsible for increasing conversion efficiency of the DSSCs.",

The coating sol was obtained by suppressed hydrolysis of Ti(OC4H9)4 through the addition of complexing molecules as stabilizers in an alcohol solution containing polyethylene glycol (PEG). Chemical changes taking place during the sol-gel process were discussed based on IR spectra analysis. A model concerning the pore formation was established to explain the role of PEG and solvent with core-shell configuration as double-templates. The structural characteristics of porous TiO2 films were found to greatly depend on the concentration and molecular weight of PEG, the types of stabilizing agents and solvents. The pore size of the films was tunable in the range of 10–500 nm and their surface area varied from 51 to 72 m2·g-1.",

The support with three-dimensional skeleton structure exhibited high porosity (higher than 90%), low density (lower than 0.25 g/cm 3 ) and high compressive strength (higher than 0.55 MPa) at 1000 °C. By controlling the mass ratio of silica sol to mullite fiber, we can obtain uniform and complete filtering layers with different thicknesses. The composite membranes exhibited high PM filtration efficiency with 99% for 1–10 µm, 97% for 0.5 µm and 90% for 0.3 µm. These samples had high air flow with very low pressure drop (lower than 600 Pa when airflow velocity reached 1 m/s). These results indicated that the silica/mullite fiber composite membranes were very promising for PM pollution control in the field of hot gas filtration.",

SiCw and CNTs show similarly optimum strengthening performance when their content in the resin is 0.75 wt% and 0.3 wt%, respectively, while the toughening performance provided by 0.75 wt% SiCw is obviously better than that provided by 0.3 wt% CNTs. For 0.75 wt% SiCw-added adhesive, SiCw shows various strengthening and toughening effect after the adhesive is calcined at different temperatures, attributing to the variation of adhesiveu0027s composition and structure in the heating process. After calcination at 1300 °C, the strengthening and toughening rate of the adhesive during the room-temperature test is up to 22.6% and 36.9%, respectively. Also, for 1300 °C-calcined adhesive, SiCw still provides sound reinforcing effect during the high-temperature test when the temperature is not above 700 °C. However, SiCw almost loses its strengthening and toughening effect when the testing temperature is above 700 °C as newly-formed borosilicate glass melts in adhesive at the temperature above 700 °C.",

"abstract": "A glow discharge plasma treatment was used to modify the impregnation method to prepare Pt / TiO2 photocatalysts with the following steps: impregnation, cold plasma treatment, calcination, and reduction. The activity and properties of the catalysts were studied in comparison with those prepared with traditional impregnation method. The activities for hydrogen generation from water/alcohols mixtures were significantly promoted. The properties including the metal dispersion, near-UV absorption, and metal stability were also enhanced. The enhanced metal dispersion and optical absorption partly promoted the activity but the effect was limited. It was speculated that the plasma method produced an enhanced metal-support interaction. According to high-resolution TEM observation, a greatly distorted metal-support interface was formed on the plasma prepared catalyst. This interface allowed a close contact between the metal atoms and support lattices, which supported the existence of the enhanced interaction. This interface was expected to facilitate the electron transfer during photocatalytic reaction and be the major reason for the high activity of the plasma prepared photocatalysts. © 2006 International Association for Hydrogen Energy.",

The effect of FACs addition on the mechanical and high-temperature performance of the FACs-HGMs/BG composites was studied. The composites containing different amounts of FACs displayed low density (0.44–0.89 g/cm 3 ), low Youngu0027s modulus (0.05–1.10 GPa), and relatively high compressive strength (2.78–9.75 MPa). Three stages, namely, elastic, plateau, and fracture stages, could be observed in the stress-strain curves. The compressive strength of the samples at high temperature was lower than the ones at room temperature, and the 10%FACs-HGMs/BG composite tested at 500 °C displayed a compressive strength of 6.03 MPa. The FACs-HGMs/BG composites demonstrating excellent mechanical properties both at room and high temperatures may be used as promising candidates for structural materials or temperature resistant buoyant materials in the near future.",

"abstract": "Abstract A temperature resistance buoyancy material was fabricated through a tert-butyl alcohol gelcasting process with borosilicate glass (BG) and hollow glass microspheres (HGMs) as the matrix and filler, respectively. The effects of the mass ratio of HGMs to BG and sintering temperature on the microstructure, thermal conductivity, and mechanical properties of the composite were studied. The results show that HGMs were bonded together by the BG, and the sample sintered at 750 °C exhibited a broad pore size distribution, from several microns to more than one hundred microns. The thermal conductivity experimental values of all the samples were less than that of Hashin-Shtrikman upper bound (HS + ) prediction but agreed well with that predicted from effective medium percolation theory. The relationship between compressive strength and relative density was predicted by the Gibson-Ashby model, with the calibration factor phi below 0.7. Young′s modulus values obtained from the experiment were below that of HS + prediction. The modulus values of the four types of samples sintered at 650 °C agreed well with the Pabst model prediction, while the values of the samples sintered at 700 °C and 750 °C were distributed in a zone between Ashby-Gibson model and HS + prediction.",

"title": "Thermal shock resistance of dense zirconia matrix composites evaluated by indentation techniques",
"abstract": "The thermal shock behavior of 3Y-TZP/LaPO 4 composites containing 0, 15, 30 vol.% LaPO 4 was evaluated with an indentation-quench method based on propagation of Vickers cracks. The effect of LaPO 4 particle size on the thermal shock behavior of 3Y-TZP/LaPO 4 composites was investigated preliminarily. Results showed that the composite containing 15 vol.% 900 °C sintered LaPO 4 exhibited better resistance to crack propagation and thermal shock under water quenching condition. Larger grain size or higher content of LaPO 4 would deteriorate the thermal shock resistance of 3Y-TZP/LaPO 4 composites. The calculation of thermal shock resistance parameter R st for the composites gives a possible explanation for the difference in thermal shock behavior. Keywords 3Y-TZP Lanthanum phosphate Indentation-quench Thermal shock resistance 1 Introduction In recent years, zirconia ceramics has attracted more and more attention as a high-technology material for industrial applications due to its excellent mechanical properties at room and moderate temperature, high hardness, wear resistance and chemical stability. However, the poor thermal shock resistance, resulting from the high thermal expansion coefficient and low thermal conductivity, to a great extent, has limited the application of zirconia ceramics. Increased thermal shock resistance can be achieved either by making it more difficult for cracks to initiate or by limiting the extent to which they can grow once cracking has started [1,2] . Obtaining useful improvements to the thermal shock resistance by preventing the initiation of cracks are difficult, particularly when the thermal shock is severe, as the crack driving forces can be many orders of magnitude greater than the resistance to fracture of ceramic materials. It is therefore more usual to try to limit the extent of crack propagation. This requires either that as much energy as possible be dissipated in growing the crack, or that the crack driving force available to each individual crack be reduced. For zirconia ceramics, this can be achieved often by increasing the porosity in the material [3] . But the increased porosity often lead to a degradation in properties such as corrosion resistance, which can be of primary importance where zirconia ceramics are required for the handling of molten metal and glass [4,5] . An alternative approach is to incorporate a ductile particulate second phase into dense zirconia matrix. Many studies have shown that the incorporation of a ductile particulate second phase into dense ceramic matrix (e.g., molybdenum in zirconia or alumina [6,7] , iron, copper, Fe 3 Al, tungsten carbide in alumina [8–11] , h-BN in SiC [12] or zirconia [13] ) can lead to an enhanced thermal shock resistance. The mechanisms of crack shielding and blunting and crack deflection have a large effect on improving the thermal shock resistance of those composites. While these composites have higher thermal shock resistance, the usefulness of them is limited by their sensitivity to oxidation. Rare earth phosphate (e.g., LaPO 4 , CePO 4 ) is a class of “ductile” material with layered structure. They were found stable to very high temperature (>1600 °C) in an oxidizing environment and suitable to fabricate composites with refractory oxide (e.g., Al 2 O 3 , ZrO 2 , or mullite) [14] . Studies have shown that the bonding between these phosphates and oxides is weak [15,16] . Mechanisms like crack blunting, branching and deflection that can prohibit main-crack growth should easily occur at the weak bonding interfaces between the two phases. Based on this theory, it was expected that the thermal shock resistance can be improved without compromising the excellent properties of dense zirconia ceramics by adding LaPO 4 particles. In our previous work [17] , it was found that the presence of monazite LaPO 4 had a positive effect on the thermal shock resistance of LaPO 4 –ZrO 2 composites. In this paper, the effect of LaPO 4 content and particle size on the thermal shock resistance of dense 3Y-TZP/LaPO 4 composites was investigated using indentation-quench method, and the growth behavior of thermal shock induced crack was further studied. 2 Experimental procedure 2.1 Materials Commercial available 3Y-TZP (99%, 0.3 μm, Zibo rare earth material Co. Ltd., Shandong, China) and LaPO 4 ·0.5H 2 O (99%, Zibo rare earth material Co. Ltd., Shandong, China) powders were used as the starting materials. In order to obtain LaPO 4 with different crystal size, the starting LaPO 4 powder was divided into two parts and calcined at 900 °C and 1250 °C for 1 h, respectively. The calcined powders were grinded and sieved through an 80 mesh before use. The specific surface area (BET method, NOVA 2000) of the two calcined powders was 2.32 m 2 /g and 0.77 m 2 /g, and the corresponding average particle size was 13 μm and 40 μm, respectively. Accordingly, they were named “fine LaPO 4 ” (900 °C) and “coarse LaPO 4 ” (1250 °C), respectively. A monolithic 3Y-TZP and three 3Y-TZP/LaPO 4 composites (containing 15 vol.% coarse LaPO 4 , 15 vol.% and 30 vol.% fine LaPO 4 , respectively)—designated as Z15L C , Z15L F , Z30L F , were fabricated by slip casting. Tap water was used as a dispersing medium and 5 vol. % (based on the volume of water) ammonium polyacrylate ( M ¯ w = 1000 , Hengsheng Chemical Co. Ltd., Shanghai, China) was chosen as a dispersant. Slurries with solid loading of 71 wt.% were then prepared by ball milling for 8 h in nylon pots with high purity zirconia balls. After degassing, slip casting was performed using gypsum moulds. The green samples were dried in an over at 50 °C for 24 h, and then pressureless-sintered in air at 1450 °C for 2 h. 2.2 Microstructure and mechanical properties The relative density of the sintered specimens was measured using the Archimedes displacement method with distilled water. Sintered specimens for flexural strength test were machined into bars with dimensions of 25 mm × 5 mm × 2.5 mm, and the top and bottom surfaces were ground flat and polished by standard diamond polishing techniques down to 10 μm. The flexural strength of the specimens was tested using a conventional three point flexural method, with a span of 20 mm and a cross-head speed of 0.368 mm/min. Measurements were performed on at least five test bars of each material. Hardness (Hv) and fracture toughness ( K IC ) at room temperature were determined from Vickers indentation tests (HV-10 Vickers hardness tester) on polished surfaces with indentation loads of 98 N and 196 N during times of 15 s, respectively. No chipping associated with any indentation was detected, and the indentations that exhibited secondary radial cracking were rejected. The principal diagonals of the plastically deformed zone and the length of the radial cracks were measured using the optical microscopy equipped on HV-10 Vickers hardness tester. The equation proposed by Niihara [18] was used to calculate the K IC . Reported Hv and K IC values are the average of ten determinations and errors are the standard deviations. XRD analysis was carried out using Rigaku D/max 2500 v/pc X-ray diffractometer (Cu/Kα, Ni filter). The volume fraction of the m-ZrO 2 ( V m ) was calculated by measuring the intensities of (1 1 1) and ( 1 ¯ 1 1 ) reflections of the monoclinic phase and the (1 1 1) peak of the tetragonal phase according to the formula of Toraya et al. [19] : (1) V m = 1.311 X m 1 + 0.311 X m (2) X m = I m ( 1 1 1 ) + I m ( 1 ¯ 1 1 ) I m ( 1 1 1 ) + I m ( 1 ¯ 1 1 ) + I t ( 1 1 1 ) where X m denotes the integrated intensity ratio, I m and I t are the peak intensities of the m-ZrO 2 and t-ZrO 2 , respectively. Microstructure characterization was by scanning electron microscopy (Philips XL-30) on fracture surfaces and on polished and thermally etched (1400 °C/45 min) surfaces (after ultrasonic cleaning with acetone and dried). 2.3 Thermal shock measurements Thermal shock tests were conducted on small discs with 4 mm in thickness that was cut from cylindrical bars of 11.5 mm diameter. They were ground and polished successively with 1000# and 2000# sandpaper and final polishing was carried out with a diamond paste of 0.5 μm. The specimens were indented using HV-10 Vickers hardness tester. The indentation load 98 N was chosen so that indentation crack sizes in the range 100–150 μm were achieved for each material. This size of the pre-racks was chosen according to the study of Pettersson et al. [20] . Four indents were made on each sample and uniformly distributed on a circle with radius of 6 mm. Each indent generated four cracks, so that 16 cracks were made on each sample. Measurements were performed on three samples of each material. The indented specimens were heated to desired temperatures for 20 min in a drop-bottom furnace and then quenched into water at room temperature. Crack extension after quenching was finally assessed through optical microscopy and SEM. 3 Results and discussion 3.1 Phase composition and microstructure Fig. 1 shows the X-ray diffraction (XRD) pattern of the monolithic ZrO 2 and 3Y-TZP/LaPO 4 composites after sintering at 1450 °C. All peaks can be identified as either ZrO 2 or monazite LaPO 4 . The content of m-ZrO 2 increased with increasing LaPO 4 content, and the content of m-ZrO 2 of Z15L C was higher than that of Z15L F ( Table 1 ). It was indicated that more spontaneous martensitic transformation occurred with the increased content of LaPO 4 in the 3Y-TZP/LaPO 4 composites during cooling from the sintering temperature. Moreover, the large grain size of LaPO 4 promoted the phase transformation. In the present experiment, the densities of ZrO 2 and LaPO 4 are 6.10 g/cm 3 and 5.08 g/cm 3 , respectively. The measured densities of sintered samples are listed in Table 2 . The relative density of Z15L F was higher than that of Z15L C , indicating that fine crystalline LaPO 4 promoted the densification process. Fig. 2 shows SEM micrographs of fractured surface of sintered specimens. The monolithic 3Y-TZP was of homogeneous structure and fine grain, and the fracture mode of it was mainly transgranular ( Fig. 2 (a)). Some fractured large sheet grain could be observed on the fracture surface of 3Y-TZP/LaPO 4 composites, indicating a mixed intergranular and transgranular cracking mode. In addition, owing to the addition of coarse LaPO 4 particle, there were more large grains in Z15L C ( Fig. 2 (b)) than in Z15L F ( Fig. 2 (c)). It was observed that Z30L F ( Fig. 2 (d)) contains coarser inclusions than that for Z15L C ( Fig. 2 (b)). The reason was that the increased content of LaPO 4 resulted in the coarsening of fine LaPO 4 . 3.2 Thermal–mechanical properties The thermal–mechanical properties of the materials are also presented in Table 2 . A general tendency was that the hardness, flexural strength and Vickers toughness of 3Y-TZP/LaPO 4 composites decreases with increasing LaPO 4 content. The decrease of Vickers hardness was directly due to the addition of soft LaPO 4 (Young's modulus of LaPO 4 is ∼100 GPa). Because of the weak-bonding interfaces between LaPO 4 and ZrO 2 , when samples were fractured, less energy was required with the increased content of LaPO 4 , thus resulting in the decrease of flexural strength. With the same content of LaPO 4 , the composite containing fine grained LaPO 4 has more weak interfaces than that containing coarse grained LaPO 4 . So, the flexural strength of Z15L F was lower than that of Z15L C . However, the more flaws generated at weak interfaces in Z15L F would improve the efficiency of microcrack toughening, thus resulting in a higher Vickers toughness. The Young's modulus and thermal expansion coefficient of 3Y-TZP/LaPO 4 composites were calculated by Eqs. (3) and (4) , respectively [21] : (3) E = E 1 V 1 + E 2 V 2 (4) α = α 1 E 1 V 1 + α 2 E 2 V 2 E 1 V 1 + E 2 V 2 where subscripts 1 and 2 denote ZrO 2 and LaPO 4 , respectively. V is the volume fraction. 3.3 Thermal shock The indentation thermal shock technique developed by Andersson and Rowcliffe [22] was used to investigate the thermal shock resistance of the 3Y-TZP/LaPO 4 composites. In this technique, two parameters, namely percentage of cracks propagated, P , and crack extension, S , were defined as follows: (5) P = Δ N N × 100 % where N (=48) is the total number of available radial cracks around the indentation and ΔN the number of radial cracks propagating after thermal shock loading. (6) S = Δ c c × 100 % where c is the average indentation crack length before thermal shock loading and Δ c the average crack length extended after thermal shock loading; only cracks which extended are considered in calculating S . Fig. 3 summarizes crack-growth behavior in the 3Y-TZP/LaPO 4 composites and pure ZrO 2 after single quench into a bath of water at room temperature. It is shown that P and S are dependent on Δ T and, the higher Δ T, the higher P and S . In all cases, the Z15L F shows the best crack-growth resistance after thermal shock, in that P and S are lower than for any of the other materials. The thermal shock resistance of Z15L C is only next to that of Z15L F , whereas Z30L F shows the poorest thermal shock resistance, which indicated that large grain size or higher content of LaPO 4 deteriorate the thermal shock resistance of 3Y-TZP/LaPO 4 composites. The partly cracks run through the surfaces for all the materials at temperature difference 250 °C. Fig. 4 shows thermal shock induced crack propagation SEM micrographs of Z15L F . Due to the addition of soft LaPO 4 , the grain pull-out was found on the polished surfaces of Z15L F , resulting in porosity over than that measured by Archimedes’ method. It was observed that thermal shock induced crack propagated along the weak interfaces between LaPO 4 and ZrO 2 , resulting in the crack deflection and bridging. The crack deflection and bridging would lead to a partial relief of the thermo-elastic strain energy and hence, contributed to resistance to crack propagation. In order to further investigate the hindering effect of LaPO 4 and the weak interfaces on the crack propagation through comparing the crack propagation behavior of 3Y-TZP and 3Y-TZP/LaPO 4 composites during thermal shock, several indentations close to each other were made on the polished surface of the samples. Fig. 5 shows the indentation cracks propagation SEM micrographs of 3Y-TZP and Z15L F . The crack propagation routes of Z15L F were more winding than those of pure ZrO 2 no matter what were before or after thermal shock. The cracks on the surface of pure ZrO 2 propagated in the original direction. But one of the cracks on Z15L F was branched and the propagation direction for the other one was changed. It was indicated that the Z15L F has better crack propagation resistance than pure ZrO 2 during thermal shock. Two different ways to evaluate the results from the indentation-quench test have been suggested: (1) use the lowest temperature difference where 25% of the cracks have grown more than 10% of their original length (Δ T 10 ) [23] , and (2) use the temperature difference where some of the cracks grow unstably out to the sample edge or stop at another indent (Δ T U ). A high Δ T 10 and Δ T U value indicates a high thermal shock resistance. The ranking of the materials, according to Δ T 10 , is as follows: Z15L F > Z15L C > 3Y-TZP > Z30L F . An expression for the prediction of Δ T U had been proposed previously [23] : (7) Δ T U = A [ K I C ( c U ) ] ( 1 − ν ) E α 1 f ′ β 1 a U where (8) A = 3 4 F π (9) β = h r k (10) f ′ β = 1 a β + b − c e − d / β Here, K IC is the fracture toughness, c U and a U are the respective crack length and crack depth at the onset of unstable crack growth, ν is the Poisson's ratio, E is the elastic modulus, α is the thermal expansion coefficient, h is the surface heat-transfer coefficient, r is the half-thickness of the sample, k is the thermal conductivity, and F is a geometric function. The parameters a , b , c , and d are constants and have values of 3.15, 1.33, 0.266, and 51.4, respectively, for an infinite plate [23] . It can be noticed that K I C ( c U ), E and α influence Δ T U directly, while h , r , and k influence via a function. For severe transient heat transfer (water quench, β ≫ 1), Δ T U is mainly determined by K I C ( c U ), E and α . So, a high K I C ( c U )/ Eα value indicates a high Δ T U . In earlier work, several thermal shock parameters (R parameters) had been defined by Hasselman. One of the parameters often used is R st . A high R st value indicates a high thermal shock resistance. R st is defined as (11) R s t = γ f E α 2 1 / 2 Since the fracture surface energy (12) γ f = K I C 2 2 E Eq. (11) is rewritten as (13) R st = K I C 2 E α Similar to Eq. (7) , Eq. (13) also indicates that the thermal shock resistance of 3Y-TZP/LaPO 4 composites can be determined by K IC ( c U ), E and α . The calculated R st values of the materials are listed in Table 2 . According to R st or Δ T U , the ranking of the thermal shock resistance of the materials, is as follows: Z15L F > Z15L C > 3Y-TZP > Z30L F , which is consisting with experiment results. 4 Conclusions Indentation techniques have been successfully used to study the thermal shock behavior of 3Y-TZP/LaPO 4 composites with different content and particle size of LaPO 4 addition. The composite containing 15 vol.% calcined (900 °C) LaPO 4 exhibited the best resistance to crack propagation. The crack deflection and bridging occurred at weak interfaces between ZrO 2 and LaPO 4 contributed to resistance to crack propagation. Larger grain size or higher content of LaPO 4 would deteriorate the thermal shock resistance of 3Y-TZP/LaPO 4 composites. The ranking of the thermal shock resistance of the materials according to calculated Δ T U or thermal shock resistance parameter R st was in good agreement with experimental results.

"abstract": "Abstract In this work, Al 2 O 3 -ZrO 2 (Y 2 O 3 ) nanocomposites were prepared by hot pressing of nanocrystalline and amorphous powders; effects of starting powders on densification and microstructure were investigated. To obtain nanocomposites with relative densities of higher than 98%, the minimum hot pressing temperature for nanocrystal powders was 1200 °C, and the resulting grain sizes were about 200 nm; for amorphous powders, however, the hot pressing temperature was as low as 1000 °C, and the products exhibited finer grains of about 90 nm. It was confirmed that, amorphous powders could be hot pressed into dense nanocomposites at lower temperatures than nanocrystalline powders, and the easier densification of amorphous powders was attributed to the higher free energy and finer particle size of amorphous particles. This work could provide new guidance for preparing bulk nanocomposites by hot pressing in both experiment and theory.",

"abstract": "Abstract In this work, Al 2 O 3 -ZrO 2 (Y 2 O 3 ) nanoceramics were prepared via pressureless sintering of powders with different degrees of crystallinity. It was demonstrated that, the crystallization of amorphous phase in starting powders highly enhanced the densification during sintering. When the crystal content was 25 vol%, the powders exhibited better sinterability than other powders, and they could be sintered into bulk nanoceramics with relative densities higher than 98% at 1400 °C and 1500 °C. The superior sinterability of C25 powders was due to the crystallization of amorphous phase promoted by the as-existed nanocrystalline powders as nucleation seeds. The obtained nanoceramic exhibited homogenously distributed ZrO 2 and Al 2 O 3 particles with grain size of about 450 nm, and displayed excellent mechanical property with Vickers hardness of 15.3 GPa, fracture toughness of 5.2 MPa m 1/2 , and flexure strength of 1190 MPa. This work may provide new guidance for optimization in preparing bulk nanoceramics by managing the crystallinity of starting powders.",

"abstract": "Abstract A room temperature curable heat-resistant adhesive with broad working temperature range was prepared through organic and inorganic modification. The preceramic polymethylsiloxane showed low bonding strength for silicon carbide from 400 °C to 600 °C because of the decomposition of polymer network. So the modification with epoxy resin was used to generate strong blending and copolymerization network which decomposed at higher temperature over 500 °C. The ceramization of active fillers and preceramic polymer compensated the bonding strength with rising temperature, thus eliminating the weak stage from 400 °C to 600 °C. The modification with fillers greatly improved its bonding strength at high temperature over 1000 °C. Consequently, the modified adhesive exhibited outstanding bonding strength tested at room temperature between 9.29 ± 0.56 MPa and 37.28 ± 1.33 MPa after heat-treatment from 25 °C to 1500 °C and the bonding strength directly tested at the temperature from 25 °C to 800 °C over 8.21 ± 0.40 MPa. The adhesive shows the potential to extend the application for engineering ceramic joining.",

"abstract": "Abstract Here a facile method to fabricate closed-cell alumina ceramics by binding hollow alumina spheres with high-temperature binder was introduced. Hollow alumina spheres as the pore-forming agent were bonded together by silica and phosphate binder to form closed-cell structure at the high temperatures. The mechanical properties of as-received closed-cell alumina ceramic can be tailored by the volume fraction of hollow alumina spheres and sintering schedule. Besides, the effects of fusing agent B 2 O 3 and chopped mullite fiber on bulk density and compressive strength of closed-cell alumina ceramics were investigated, respectively. The results indicated that the addition of chopped mullite fiber can effectively enhance the compressive strength of the closed-cell alumina ceramic without significant change in bulk density. The compressive strength of the closed-cell alumina ceramics with 62.5% total porosity was 11.97 MPa when 5 wt% B 2 O 3 and 6 wt% chopped mullite fibers were added in the sample.",

"abstract": "Near-net-shaped hierarchical structure-adjustable short mullite fibers/mullite whiskers frameworks (MF/MW frameworks) were prepared by slurry-filtration and heat-treating method. The main structure of MF/MW framework was constituted by lap-jointed mullite fibers. Every single fiber in the framework was densely covered by mullite whiskers which formed through fluorine-catalyzed gas-phase reaction, and the fibers actually served as curved substrates for the mullite whiskers' growth. The lap-jointing points of the fibers were served by movable intersected mullite whiskers. Moreover, the microstructure of the frameworks could be adjusted by tailoring the raw materials mass ratio. The volume densities, the apparent porosities and the thermal conductivities of the MF/MW frameworks in different raw materials mass ratios were 0.459-0.487 g/cm3, 79.7-82.8% and 0.1356-0.1965 W/k m, respectively. The compression-resilience property of the samples was tested under 0.4 MPa at room temperature. The compression ratio and resilience ratio of the MF/MW frameworks in different raw materials mass ratios were 1.63-2.25% and 92.67-98.16%, respectively. The MF/MW frameworks with advanced thermal and mechanical properties were considered to be promising high-temperature heat-insulation material. ? 2013 Elsevier Ltd and Techna Group S.r.l.",

The basic structural characteristics of the as-synthesized Cu2-xSe nanoplates are described. The influence of temperature, reaction time and the amount of added polyvinylpyrrolidone on the synthesis product were investigated by X-ray diffraction, high-resolution transmission electron microscopy, energy dispersive X-ray spectroscopy and UV-vis-NIR measurments. The results showed that the resulting cubic Cu2-xSe phase was thermodynamically stable when the initial Cu:Se atomic ratio in the reaction solution was 2:1. The high injection temperature was suitable for the formation of single-phase Cu2-xSe nanoplates with relatively uniform sizes.

"abstract": "Abstract Accurately establishing the relationship between the network architecture characteristics and performance of fibrous porous ceramics is instructive for structural design and performance control. In the present work, fibrous, high porous (82.87–90.02%), low density (0.247–0.512 g/cm 3 ) and low elastic modulus (50.62–188.56 MPa) mullite ceramics were fabricated by freeze casting. The three dimensional network architectures were characterized by X-ray tomography technique and quantitatively analyzed by 3D image analysis software (imorph, www.imorph.fr ). The radius (5.04 µm), types, lengths (64.72–96.49 µm) and orientations (0.87–1.45, anisotropy parameter) of fiber segments in the network architecture were investigated. The extracted results were employed to predict the Youngu0027s modulus of the mullite fibrous porous ceramics according to a model based on the bending and axial compression of single fiber segment. The predicted Youngu0027s modulus agreed well with the experimental results. The differences of Youngu0027s modulus and Poisson ratio between the prediction and the model of Markaki and Clyne were compared. The comparison showed that the difference became larger when the aspect ratio of the fiber segment was less than 6 due to the effect of axial compression. The predicted Poisson ratio had a certain dependence on fiber segment aspect ratio and got close to the constant (1/π) reported by Markaki and Clyne with the increase of fiber segment aspect ratio.",

The effects of fiber character, cooling temperature and slurry viscosity on the structure formation were investigated. The structure and properties of the fibrous porous ceramics were determined by two factors: the fiber network and the dispersion of binders. The cooling temperature and slurry viscosity affected the dispersion of the particles rejected by the solidification front while the fiber length affected the fiber network. The material with optimal properties was obtained with 5 wt% PVA, 5 wt% silica sol and 1 vol% alumina fibers when freezing at −20 °C.

"abstract": "Diamond crystals in nanometric range have been synthesized in graphite suspension by pulsed laser irradiation,and the effects of three kinds of carbon material( carbon black,crystalline flake graphite and mi- crocrystalline graphite)on the formation of diamond are analyzed.The structures of the carbon materials are characterized by Raman spectra which show that the crystallization degree increases from carbon black,micro- crystalline graphite to crystalline flake graphite in turn.The structures of the products after Nd:YAG laser irra- diation are characterized by transmission electron microscopy(TEM).The experiment results show that only mi- crocrystalline graphite by laser transformed into diamond( cubic diamond about 5 nm)in the three carbon mate- rials.It also demonstrates that microcrystalline graphite is more advantageous in the synthesis of nanodiamond than carbon black and crystalline flake graphite when the laser power density is 10~6 W/cm~2.",

"abstract": "Abstract Porous mullite fiber/silica composite was successfully fabricated by a TBA-based gel-casting, and the influence of mullite fiber content on the composite microstructure and properties were investigated. The results show that the mullite fiber content played an important role in tailoring the microstructure of the composite, consequently influencing the sample properties. The composite fabricated with high fiber content showed a porous fibrous structure with mullite fibers as the fiber skeleton and silica as the binder, and exhibited a low density, high porosity, excellent elasticity and low thermal conductivity. On the contrary, the sample fabricated with low fiber content possessed a high density and high strength due to its dense microstructure which is similar with that of the fiber reinforced ceramic matrix composite.",

Borosilicate glass (BG) and hollow glass microspheres (HGMs) with different average diameters were used as the matrix and the filler, respectively. Results show that the compressive strength increased with the decrease of the mean diameter of HGMs, and the sample consisting of the filler of HGMs with a small average diameter exhibited high compressive strength of 25.04 MPa. Youngu0027s modulus values of the composite sintered at 700 °C and 750 °C were distributed over in the range of the values predicted from Ashby-Gibson model to Hashin-Shtrikman model and other moduli values agreed well with that of Past model prediction. Weibull moduli ( m ) reflecting the variation degree of the sample compressive strength were in the range of 5–15. The compressive strength of the composites composed of the HGMs with small average particle size tested at 500 °C was as high as 7.94 MPa.",

"abstract": "The mechanisms of the stearamide derivative inhibited CO2 corrosion on the mild steel X65 were studied in derivative containing aerated brine solution by electrochemical polarization measurements and electrochemical impedance spectroscopy (EIS) measurements. The electrochemical data showed that the corrosion resistance was greatly enhanced in the presence of stearamide derivative inhibitor. Polarization curves revealed that the inhibitor is an anodic type inhibitor, belonging to interface adsorbtion, and the inhibition is due to the negative catalytic mechanism. The maximum inhibition efficiency appeared at a concentration of inhibitor of 0.5 g/L. EIS has two time constants and the equivalent circuit was suggested as R(C(R(CR))).",

METHODS The samples were processed by LLE( liquid-liquid extraction),acetonitrile-ammonium acetate( 0. 1‰ formic acid)-water was used as the mobile phase with isocratic elution( 25∶ 37. 5∶ 37. 5 in plasma,35 ∶ 6 ∶ 59 in urine),and separation was carried out on Welch Material Ultimate AQ-C18column( 2. 1 00 × 100 mm,3. 5 μm),setting the flow rate as 0. 35 mL·min-1,the column temperature at 25 ℃. The injection volume was 5 μL. ESI under positive ion mode and multiple reaction monitoring scan( MRM) were used for quantitative analysis with m / z 273. 4→110. 2 for pilsicainide and m/z 287. 4 →110. 2 for internal standard,methyl-pilsicainide. RESULTS The linear ranges of the calibration curves for pilsicainide were 1-1 200 μg·L-1for plasma and 1-150 mg·L-1for urine. The limitation of detection were 1 μg·L-1for plasma and 1 mg · L-1for urine. The correlation coefficient was between 0. 996 2 and 0. 999 1. The extraction recoveries,matrix effects,and intra-/ inter-assay precisions all met the requirements of pharmacokinetic studies. This approach was applied to determine pilsicainide concentrations in human plasma and urine in a clinical pharmacokinetic research. CONCLUSION This approach possesses convenience,accuracy,high sensitivity and good reproducibility,which can meet the requirements of pharmacokinetic studies.",

The phosphor exhibited red luminescence under the near-UV excitation of 395 nm, corresponding to the F-5(0)-> L-7(6) transition of Eu3+ ions, which matched well with the excitation wavelength of near-UV LED chips. The electronic transition due to D-5(0)-> F-7(2) transition of Eu3+ ions is stronger than the magnetic dipole transition due to D-5(0)-> F-7(1) of Eu3+ ions. Furthermore, Eu3+-doped NaSrPO4 phosphor shows higher thermally stable luminescence comparable to commercially available Y3Al5O12:Ce3+ phosphor. All the investigated suggested that this newly developed phosphor could find applications in white light devise utilizing InGaN-based excitation in the near-UV chips.",

"title": "Upconversion luminescence properties of NaYF4: Tm3+ , Yb3+ synthesized by co-precipitation method",
"abstract": "The upconversion (UC) processes of infrared light to visible light of rare earth ions doped different hosts have been investigated extensively, due to their potential applications in some fields, such as solid-state lasers, display, communications, and so on. The recent researches emerging at the intersection of nanotech-nology and biotechnology are opening up a new period for the development of UC. As known, the controlled fabrication of a host with aimed structure is important for enhancing the upconversion efficiency, because the phonon energy of the host can affect the probabilities of non-radiative decay and die energy transfer. There-fore, it is necessary to choose a lattice with much lower phonon energy, which is benefit to the upconversion luminescence. Rare earth-doped hexagonal sodium yttrium fluoride (NaYF 4) is a good host, which is known to be a very efficient near-infrared to visible upconverter. The hexagonal NaYF4has low phonon energy. The structure of hexagonal phase gives rise to controversy about the cation sites and distribution. The trivalent thu-lium (Tm3+) is an ideal candidate for single wavelength NIR upconversion due to its ladder of nearly equally spaced energy levels that are multiples of the 1G 4→3H6transition. The development of compact blue lasers based on Tm3+ upconversion processes is nowadays widely studied mainly due to the potential of high perfor-mance OEM applications, such as biomedical and analytical instrumentation, display, photoprinting. In thu-lium doped media, the efficiency of this process is very low, but it was noticed that the mechanism could be made one or two orders of magnitude more efficient by using ytterbium (Yb3+). In this paper, trivalent thu-lium (Tm3+) and yttebium (Yb3+) ions codoped NaYF4 were synthesized by co-precipitation method. The concentration of Tm3+ and Yb3+ are 0.01% , 0.1% , respectively. The absorption spectrum of NaYF4:Tm3+,Yb3+ from 300 to 1 100 nm was measured at room temperature. The upconversion emission was observed when excited by 798 nm. The green and blue upconversion emission spectra were measured. Based on the experi-mental results the possible upconversion mechanism was analyzed. The main mechanism is the in-direct sensi-tization of Tm3+andYb3+. The blue emitting light results from the transition of 1G4→1H6 of Tm3+, green emitting light is from the transition of 1D2→3F4 of Tm3+. To our knowledge, there have not been similar works published domestically and abroad. The structural properties of the samples were characterized by X-ray dif-fraction (XRD) and scanning electron microscopy (SEM). The results show that NaYF4: Tm 3+, Yb pre-pared by co-precipitation method exhibits hexagonal crystal phase.",

"abstract": "This work focuses on the synthesis of morphology-controlled BaMoO 4:Eu 3+ micro-crystals such as microparticles and micro-rods using a facile molten salt method, and their morphology, structural characterization, and luminescent properties were comparatively investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and fluorescence spectra. The molten salt method synthesized products from a reaction of BaMoO 4 precursor obtained by a co-precipitation method of BaCl 2 and Na 2MoO 4 with an eutectic salt mixture of NaCl-KCl at 700 °C. Detailed studies revealed that the formation of the different morphologies of the micro-crystals was strongly dependent on the weight ratio of the salt (NaCl-KCl) to the BaMoO 4 precursor, and the formation mechanism of the products in the present molten salt system was also investigated. Based on the investigations of the photoluminescence properties, the samples with different morphologies prepared by the molten salt method had the strongest red emission at 615 nm, corresponding to the Eu 3+ 5D 0? 7F 2 transition in the BaMoO 4 host lattice, and the emission intensity of BaMoO 4:Eu 3+ microparticles was stronger than that of BaMoO 4:Eu 3+ micro-rods. © 2011 American Scientific Publishers.

"abstract": "Yb3+/Tm3+/Ho3+ tri-doped Gd 2Mo3O9 phosphors were synthesized by the high-temperature solid-state method. Under 980 nm near-infrared excitation, the white-light emission can be observed, which is consists of the blue, green, and red UC emissions. The green and red emission at 547 nm and 660 nm originated from the transition of Ho3+ (5S2, 5F4 → 5I8 and 5F5 → 5I8) and the blue emission at 475 nm attributed to the transition of Tm3+ ( 5G4 → 5H6). In this experiment, we selected the optimum concentration ratio of the three rare earths for the bright white emission. The Commission internationale de L'Eclairage (CIE) coordinates for the samples were calculated, and chromaticity coordinates were very close to white light regions. We find that the calculated CIE color coordinates of the Yb3+/Tm3+/Ho3+ tri-doped Gd2Mo3O9 phosphors changed with the incident pump power from 400 mW/cm2 to 1000 mW/cm2. The upconversion luminescence mechanism of the samples was discussed on its spectral. The white light may be proved to be a candidate material for applications in various fields. © 2013 Elsevier B.V.

The SEM, TEM and HRTEM images show that the two samples include BiVO4 nanoparticles supported onto TiO2 nanowires. The UV-Vis absorption spectra reveal that the absorption edges of the samples exhibit red-shift in comparison with that of the pure TiO2 nanowires.

"abstract": "Alkali earth chlorosilicate of the type Sr(4-x)Ca(x)Si3O8Cl4 was synthesized through the high temperature solid state method. According to the Van Uitert experimental equation, luminescence properties and crystal-lattice environment of Eu2+ in Sr(4-x) Ca(x)Si3O8Cl4 crystal were discussed. The possibilities of two Eu2+ emission centers, viz. blue and greenish-yellow centers, were found and their corresponding relationships with spectra were also discussed. When the doping amount of calcium(x) varied between 0 and 0.5, Ca2+ ions were embedded in the host lattice of Sr4Si3O8Cl4, and the luminescence of blue center, which was ascribed to the emission of Eu2+ that substituted the octa-coordination Sr2+ sites, dominated and showed blue-green luminescence. Sr(4-x)Ca(x)Si3O8Cl4:yEu2+ exhibited greenish-yellow luminescence when the range of x was between 0.5 and 2. This was due to the fact that the Eu2+ emission originated from the formation of an impurity-trapped exciton state. Greenish-yellow emission center was located in the impurity-trapped exciton state which was the lowest excited state of this system, and the Eu2+ emission was at long wavelengths, and a large Stokes shift was observed.",

Their luminescent properties were characterized by using powder X-ray diffraction, photoluminescence excitation and emission spectra, lifetime, and temperature dependent emission spectra, respectively. The NaSrPO 4:Eu 2,Tb 3,Na phosphor showed an intense broad excitation band between 250 and 430 nm, which was in agreement with the near-UV chip (350-420 nm), and it exhibited two dominating emission bands at 445 and 545 nm, corresponding to the allowed 4f 65d 1→4f 7( 8S 7/2) transition of Eu 2 ion and the 5D 4→ 7F 5 transition of Tb 3 ion, respectively. The emission intensity and lifetime of Eu 2 ion decreased with the increasing concentration of Tb 3 ion, which strongly indicated that an effective energy transfer occurred from Eu 2 to Tb 3 in NaSrPO 4 host.

The authors have analyzed the measured luminescence spectra and decay lifetimes for different Yb concentrations and proposed a mechanism to rationalize the DC effect. The maximum quantum efficiency (QE) of Nd is up to 164.03 %. Application of the broadband NIR-QC phosphors might enhance the performance of silicon-based solar cells.",

"abstract": "A novel near-infrared (NIR) downconversion (DC) phosphor KSrPO4 :Eu2+ , Pr3+ is synthesized by the conventional high temperature solid-state reaction. The Eu2+ acts as an efficient sensitizer for Pr3+ in the KSrPO4 host. With broad-band near-ultraviolet light excitation induced by the 4f→5d transition of Eu2+ , the characteristic NIR emission of Pr3+ , peaking at 974 nm and 1019 nm due to 3P0 → 1G4 and 1G4 → 3H4 transitions, is generated as a result of the energy transfer from Eu2+ to Pr3+ . The luminescence spectra in both the visible and the NIR regions and the decay lifetime curves of Eu2+ prove the energy transfer from Eu2+ to Pr3+ . This Eu2+ and Pr3+ co-doped KSrPO4 phosphor may be a promising candidate to modify the spectral mismatch behavior of crystalline solar cells and sunlight.",

Upon excitation of Tb3+ with a visible photon at 485 nm, two NIR photons could be emitted by Yb3+ through cooperative energy transfer (CTE) from Tb3+ to two Yb3+ ions. Excitation and emission spectra as well as fluorescence decay measurements have been carried out to examine the occurrence of cooperative energy transfer (CET) from Tb3+ to Yb3+ ions.

The upconversion luminescence properties of two-ion and three-ion co-doped KGd(WO 4)2 phosphors were investigated in detail. The concentration quenching effect of the two-ion co-doped KGd(WO4) 2 phosphors was studied, and the optimum concentration of Ho 3+, Er3+ and Tm3+ are 2 mol., 2 mol. and 3 mol., respectively. The Yb3+/Ho3+/Tm3+ co-doped KGd(WO4)2 sample is the best white upconversion luminescence material among three-ion co-doped KGd(WO4)2 phosphors. The CIE coordinates for the samples were calculated, and chromaticity coordinates were close to white light regions. The upconversion luminescence mechanism of the samples was discussed. The upconversion luminescence of Ho 3+ and Er3+ was both produced through two-photon process. The emissions of Ho3+ at 546 and 654 nm originated from the transition of Ho3+ (5S2→5I 8 and 5F5→5I8), while those of Er3+ at 530 and 551 nm were attributed to the transition of Er3+ (2I11/2→ 4I15/2 and 4S3/2→ 4I15/2). The upconversion luminescence mechanism of Tm3+ was a three-photon process. The blue emission of Tm3+ was due to the transition of Tm3+ (1G4→ 3H6). © 2010 The Chinese Society of Rare Earths.",

The magnetic results demonstrated that the prepared Ni-doped TiO2 samples had complex magnetic mechanism including room-temperature ferromagnetic and paramagnetic behaviors, and with the increase of Ni2+ content, the magnetization also increased under the same applied field owing to uniform distribution of Ni2+ ions in TiO2 nanobelts.",

The SiO 2 coating is obtained by the ultrasonic sonochemical process using tetraethylorthosilicate (TEOS) as silicon coating reagent and the coating content is varied from 0.5 to 2 wt%. Powder X-ray diffraction (XRD) patterns, scanning electron microscopy (SEM), fluorescence spectrometer, and Fourier transform infrared spectrometer are employed to characterize the coating. Moisture resistances of coated SrSO 4:Sm 3+ phosphors have been enhanced to a great degree without more loss of their optical properties based on the existence of the SiO 2 thin layer.

"abstract": "Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 phosphors were synthesized by the high-temperature solid-state method. Bright white luminescence upon 980 nm near-infrared excitation can be observed for the sample at the optimum chemical composition of Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Tm 3+ /0.4%Ho 3+ , which is produced via an upconversion (UC) process by tuning the dopant ions concentration. The measured white light consists of the blue, green, and red UC emissions which correspond to the transitions 1 G 4 → 3 H 6 of Tm 3+ , 5 F 4 ( 5 S 2 ) → 5 I 8 , and 5 F 5 → 5 I 8 of Ho 3+ ions, respectively. The calculated color coordinates display that white light can be achieved in a wide range of dopant concentrations. The UC mechanisms were also proposed based on their spectral and pumping power dependence analyses. Keywords A. Optical materials C. X-ray diffraction D. Optical properties 1 Introduction Lanthanide (Ln 3+ )-doped luminescence materials are particularly attractive in both the academic and industrial fields due to their unique optical properties arising from the intra-4 f transitions [1] . Recently, a growing interest has been focused on white light-emitting diodes (w-LEDs), especially phosphor-converted w-LEDs, because of their high luminous efficiency, long lifetimes, low environmental impact, and small structure type [2,3] . Therefore, many Ln 3+ -doped luminescence materials based on the blue and near ultraviolet (NUV) light excitation have been developed in order to obtain white light emission [4,5] . Since photon upconversion (UC) can also be used for the generation of visible emission by near-infrared (NIR) excitation of Ln 3+ -doped materials, one technical problem in UC materials is the exploration of those phosphors that can be excited with commercially available NIR diode lasers and exhibit white upconversion luminescence, which also should possess a degree of brightness comparable to those excited conventionally using NUV light, and this strategy has been proved to be very promising [6–8] . Some efforts have been made to develop white light emission Ln 3+ -doped materials via UC process, for example, Sivakumar et al. [9] reported the white UC luminescence SiO 2 , ZrO 2 sol–gel thin film made with Ln 3+ (Tm 3+ , Er 3+ , Eu 3+ )-doped LaF 3 nanoparticles codoped with Yb 3+ ions. After that, single-phase rare earth oxide matrices, such as Y 2 O 3 [10] , Lu 2 O 3 [11] , Lu 3 Ga 5 O 12 [12] , Gd 2 (MoO 4 ) 3 [13] and La 2 (MoO 4 ) 3 [14] have also been reported as white UC luminescence host, which is related to the combination of upconverted blue (from Tm 3+ ), green, and red (from Er 3+ ) emissions to produce the white luminescence. Despite these reports, there is a continuous demand for new and efficient white light UC materials in advanced technological applications. It is well-known that the rare earth tungstate and molybdate matrix are highly chemically, photothermally, and photochemically stable and have a broad optical transparence from the visible to the NIR regions [15] . In this paper, we report the synthesis of Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 UC luminescence materials prepared by the high-temperature solid-state method. Compared with the conventional Yb 3+ /Tm 3+ /Er 3+ combination as the white UC emission ions [10–12] , this is another novel result on Yb 3+ /Tm 3+ /Ho 3+ combination as the white UC emitter. Their white UC luminescence properties and mechanisms are also investigated in this paper. 2 Experimental The powder samples of Yb 3+ /Tm 3+ , Yb 3+ /Ho 3+ , and Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 materials were prepared by the traditional high-temperature solid-state reaction. The starting materials were Na 2 CO 3 (A.R.), 5(NH 4 ) 2 O·12WO 3 ·5H 2 O (A.R.), Gd 2 O 3 (99.99%), Yb 2 O 3 (99.99%), Tm 2 O 3 (99.99%) and Ho 2 O 3 (99.99%). For the typical synthesis of 10%Yb 3+ /1%Tm 3+ /0.4%Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 powders, the calculated starting compositions are as follows: 0.25 Na 2 CO 3 + 1/12 5(NH 4 ) 2 O·12WO 3 ·5H 2 O + 0.193 Gd 2 O 3 + 0.05 Yb 2 O 3 + 0.005 Tm 2 O 3 + 0.002 Ho 2 O 3 . The weighed raw materials were thoroughly mixed in an agate mortar and then placed in an alumina crucible with a lid. Then, the samples were sintered for 4 h at the selected temperature, 600 °C, 700 °C and 800 °C. The phase structure of the as-synthesized Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 materials was determined by X-ray powder diffraction spectroscopy (XRD, Shimadzu XRD-6000) operating at Cu Kα radiation, 40 kV, 30 mA, and a scan speed of 2.0° (2 θ )/min. Microstructure evolution was observed using a scanning electron microscopy (SEM) (JEOL, JSM-6490). The UC luminescence spectra were recorded on a Hitachi F-4500 spectrophotometer equipped with an external power-controllable 980 nm semiconductor laser (Beijing Viasho Technology Company, China) as the excitation source, which is connected with an optic fiber accessory. The CIE chromaticity coordinates of this work were calculated by the UC spectra based on the 1931 CIE standard. 3 Results and discussion Fig. 1 a shows the XRD patterns of Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 sample prepared at different temperatures, 600 °C, 700 °C, and 800 °C. It is found that the XRD patterns of the samples with different synthesis temperatures are very similar, only several low impurity diffraction peaks around 24° can be found when the synthesis temperature is below 800 °C. Therefore, the optimum synthesis temperature for Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 sample can be fixed as 800 °C in our experiment. It is also found from Fig. 1 a that the peak positions agree well with those of the standard pattern (JCPDS no. 25-0829) for Na 0.5 Gd 0.5 WO 4 in scheelite structure, which has tetragonal symmetry (space group I 4 1 / a ) with the lattice constants of a = 5.243 Å, c = 11.36 Å, and υ (cell volume) = 312.50 Å 3 [16] . It indicates that the crystal lattice and basic structure of Na 0.5 Gd 0.5 WO 4 host can be obtained successfully, and the Ln 3+ cations replace the Gd 3+ which is eightfold coordinated by oxygen atoms with D 2d point symmetry. SEM image ( Fig. 1 b) shows that the morphology was nearly prismatic like shape and the particle size is about 1–3 μm. The observed results from the as-prepared Na 0.5 Gd 0.5 WO 4 phosphor particles with prismatic like shapes also confirm the characteristic growth of the sample with tetragonal phase microstructure. It is known that the co-doping behavior can increase the efficiency of luminescence, and also induces UC luminescence between the donor and acceptor ions in some cases [13,14,17] . Yb 3+ was chosen as the co-doping ion with Tm 3+ or Ho 3+ , because it possessed a large absorption cross-section at 980 nm. Therefore, the UC spectra of Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Tm 3+ and Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Ho 3+ samples under 980 nm excitation with pumping power of 20 mW were measured and illustrated in Fig. 2 a . As seen in Fig. 2 a, Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Tm 3+ samples show a strong blue luminescence at 473 nm, corresponding to the Tm 3+ 1 G 4 → 3 H 6 transition. Whereas, Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Ho 3+ samples show the bright orange emission, which is ascribed to the combination of the two primary bands in the green and red emission regions maximized at 543 nm and 655 nm, and they are assigned to Ho 3+ 5 F 4 ( 5 S 2 ) → 5 I 8 (543 nm), and Ho 3+ 5 F 5 → 5 I 8 (655 nm) transitions, respectively. The present results prove that Tm 3+ - and Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 can emit their corresponding characteristic UC luminescence upon 980 nm excitation. To estimate the possibility of producing white UC luminescence in the same sample with only one excitation wavelength, the Na 0.5 Gd 0.5 WO 4 materials doped with various concentrations of Yb 3+ /Tm 3+ /Ho 3+ have been firstly investigated in this study, and their UC spectra are given in Fig. 2 b. It is found that each emission spectrum consists of the blue, green, and red UC emissions which correspond to the transitions 1 G 4 → 3 H 6 of Tm 3+ , 5 F 4 ( 5 S 2 ) → 5 I 8 , and 5 F 5 → 5 I 8 of Ho 3+ ions, respectively. Further, by fixing the Yb 3+ and Tm 3+ concentrations, color-tunable UC emission properties can be found when adjusting Ho 3+ concentration. Among them, 10%Yb 3+ /1%Tm 3+ /0.4%Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 sample shows a strong white light emission and is clearly visible to the naked eye at a pumping power as low as 20 mW demonstrating the high efficiency of the upconversion process. In order to find the detailed variation of UC emissions behaviors [10,11] , Fig. 3 a gives the dependence of the intensities of the blue (477 nm), green (543 nm) and red (655 nm) emission bands on the Ho 3+ content with the invariable Yb 3+ and Tm 3+ content. As shown in Fig. 3 a, the emission intensities of green, and red light, which originate from the different transitions of the same Ho 3+ ions, have the same variation, and increase with increasing Ho 3+ content. While the emission intensity of blue light, ascribed to 1 G 4 → 3 H 6 of Tm 3+ , firstly increase, and then decrease with increasing Ho 3+ content. As a summarization, Table 1 lists various optical property parameters for the Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Tm 3+ / x Ho 3+ samples. It is also found that 10%Yb 3+ /1%Tm 3+ /0.4%Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 sample has equal relative intensities ratio of 1:1.02:0.91 for blue, green, and red UC emissions. To measure the color of the visible emission that the human eye perceives, the Commission Internationale de l′éclairage (CIE) coordinates were calculated. The calculated color coordinates for the Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Tm 3+ / x Ho 3+ samples are listed in Table 1 , and it is also marked as sites a–e in CIE chromaticity diagram, which all fall within the valid range for the white light emission ( Fig. 3 b). As also given in the inset of Fig. 3 (b), the white light emission can be clearly observed from the digital photograph. So we can propose that the white luminescence upon 980 nm near-infrared excitation can be produced via an UC process by tuning dopant ions based on the above spectral analysis. But we also noticed that future work is needed to be done to further adjust the relative concentrations for the dopant ions in order to optimize white light emission in this system. To investigate the UC mechanisms, Fig. 4 gives the UC luminescence spectra for Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Tm 3+ /0.4%Ho 3+ samples under 980 nm excitation at different pumping power. The UC emission intensities increase gradually with increasing pumping power from 20 mW to 60 mW. Based on the UC luminescence spectra, the upconverted luminescence intensity I of the blue ( 1 G 4 → 3 H 6 of Tm 3+ ), green ( 5 F 4 ( 5 S 2 ) → 5 I 8 of Ho 3+ ), and the red ( 5 F 5 → 5 I 8 of Ho 3+ ) transitions was measured as a function of the pumping power P , and the pumping power dependences of the blue, green, and red radiations were measured and displayed in the inset of Fig. 4 . The relationship between luminescence intensity I and pumping power P can be approximately expressed as follows: log( I ) ∝ (log P ) n , where n is the number of infrared photons absorbed for emitting a visible photon [10,14] . In the double-log coordinate, the slope of log( I ) ∝ (log P ) n indicates the value of n , which is used for the deduction of the possible upconversion luminescence process. As shown in the inset of Fig. 4 , the slope of curve log( I ) versus (log P ) was determined to be 2.38, 1.86, and 1.75 for the blue, green, and red emissions, respectively, allowing us to therefore propose that two-photons process in the green and red Ho 3+ UC luminescence processes. And a three-photon process was expected for the upconverted blue Tm 3+ emission. Accordingly, Fig. 5 shows the energy level diagrams of the Tm 3+ , Ho 3+ , and Yb 3+ ions as well as the proposed UC mechanisms to produce the white emission in Na 0.5 Gd 0.5 WO 4 host. It is well-known that the Yb 3+ ions can efficiently sensitize Tm 3+ and Ho 3+ ions, respectively. Hence, it is reasonable to believe that the main pathways to produce visible light also come from the energy transfer processes from Yb 3+ to Tm 3+ and Ho 3+ ions, respectively. It is found that the blue UC emission comes from the Yb 3+ –Tm 3+ pairs via a well-known three-photon process, while the green and red bands arise from Yb 3+ –Ho 3+ pairs via a two-photon process, as shown in Fig. 5 . By adjusting the relative concentration of Yb 3+ /Tm 3+ /Ho 3+ for the control of emission intensities of blue, green, and red UC emissions, bright white luminescence upon 980 nm semiconductor laser excitation can be realized via the mentioned above UC process. 4 Conclusions In conclusion, white light emission from Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 materials is achieved in the present study, and the optimum chemical composition of Na 0.5 Gd 0.5 WO 4 :10%Yb 3+ /1%Tm 3+ /0.4%Ho 3+ as white light phosphor has been determined. Bright white luminescence upon 980 nm semiconductor laser excitation comes from the combination of the blue, green, and red UC emissions which correspond to the transitions 1 G 4 → 3 H 6 of Tm 3+ , 5 F 4 ( 5 S 2 ) → 5 I 8 , and 5 F 5 → 5 I 8 of Ho 3+ ions, respectively. The calculated optimum color coordinates for white UC luminescence Yb 3+ /Tm 3+ /Ho 3+ -doped Na 0.5 Gd 0.5 WO 4 materials are (0.25, 0.39), which fall well within the white region. Generation of white light from Ln 3+ -doped rare earth tungstate matrix has potential application for lighting and displays.

"abstract": "A new intense green light-emitting phosphor, the Eu2+-doped (BaO-BaCl2-SiO2) phosphor system, was synthesized at 800°C by the conventional high-temperature solid-state reaction. Its structure and luminescence properties were investigated by using thermogravimetry-differential scanning calorimetry (TG-DSC), X-ray diffraction (XRD), diffuse reflection spectra, photoluminescence (PL) and photoluminescence excitation (PLE) spectra. The photoluminescence spectrum reveals that this phosphor can be efficiently excited by near-ultraviolet (UV) light and blue light in the wavelength region covering 280 and 480 nm, which perfectly matches the emission wavelength of near-UV light-emitting diodes (LEDs). It emits an intense green light peaking at 502 nm, which is promising to develop possible applications for white LEDs. © 2009 Springer-Verlag.",

Upon excitation of Eu2+ with an ultraviolent (UV) photon at 343 nm, two NIR emissions have been obtained from 2F7/2 → 2F5/2 transition of Yb3+. The luminescence spectra both in visible (VIS) and NIR regions and decay lifetime curves of Eu2+ have been measured to prove energy transfer (ET) from Eu2+ to Yb3+. The highest energy transfer efficiency (ETE) related to Yb3+ concentration was found to be 85.3%.

The phase formation of phosphors was confirmed by X-ray powder diffraction (XRD). The excitation spectra exhibited that the phosphors could be effectively excited by near ultraviolet (392 nm) and blue (464 nm) light, which perfectly match the emission wavelength of near-UV light-emitting diodes (LEDs). The emission spectra showed that two characteristic red emission lines peaking at 592 and 613 nm can be obtained upon 394 and 463 excitation with the chromaticity coordinates of (0.6347, 0.3649), which are due to D-5(0)-F-7(1) and D-5(0)-F-7(2) transitions of Eu3+ ions. The effect of Eu3+ concentration on the emission spectrum of Na3CaB5O10:Eu3+ phosphor was studied. The results showed that the emission intensity increased with increasing Eu3+ concentration, and then decreased because of concentration quenching. The obtained results indicated that this phosphor could be a promising candidate for near-UV white LEDs.",

The color of upconversion luminescence of NaYF4:Eu,Tm,Yb excited by 980 nm was blue and red. The upconversion spectrum exhibits distinct emission peaks at 459, 478 and 641 nm. The blue light comes from the transition of (1)G4--(3)H6 and (1)D2-->(3)F4 of Tm3+. The absorption spectrum was also researched. The red light results from the transition of (1)G4--(3)F4 of Tm3+. The slope of the emission of 474 and 646 nm is 2.1 and 2.4 respectively. The emission of 478 and 641 nm is all due to three photon process.

The color of the compound in acetone solution changed from colorless to blue after irradiated by 365 nm UV, and returned to colorless when the irradiation was stopped or in dark. This phenomenon occurrence is because the reversibility of the transformation between the colorless spiro forms and the colored merocyanines.

The photoluminescence studies on Sr2Ca1−2x\n Eu\n x\n Na\n x\n MoO6 (x = 0.02, 0.05, 0.10, 0.15, 0.2) show that a dominant red emission line at around 594 nm, which is due to the Eu3+ magnetic dipole transition of 5D0–7F1, is observed under different Eu3+ excitations (396 and 412 nm). Further, Eu3+ dopant content dependent emission spectra investigations of Sr2Ca1−2x\n Eu\n x\n Na\n x\n MoO6 phosphors indicates that, when the Eu3+ concentrations x = 0.05, there are minimum differences between the emission intensity of 5D0–7F1 transition at 594 nm and that of 5D0–7F2 transition at 615 nm. With increasing Eu3+ concentration, the variation of the emission intensities between the two transitions keep nearly invariable and Sr2Ca0.8Eu0.1Na0.1MoO6 phosphor has the strongest red emission in this series.",

"title": "Structure and upconversion luminescence properties of BaYF 5:Yb3+, Er3+ nanoparticles prepared by different methods",
"abstract": "Research highlights ▶ Two different fluoride source were used to synthesize BaYF 5 :Yb 3+ , Er 3+ by the hydrothermal method, and the sizes of the as-prepared spherical particles were about 30 nm (NH 4 BF 4 as fluoride source) and 100 nm (NH 4 HF 2 as fluoride source). ▶ BaYF 5 :Yb 3+ , Er 3+ nanoparticles prepared by the co-precipitation method are irregular, and many clusters and agglomerates can be seen. ▶ The UC fluorescence has been realized in all the as-prepared BaYF 5 :Yb 3+ , Er 3 samples upon 980 nm excitation. Abstract BaYF 5 :Yb 3+ , Er 3+ (BYF) upconversion (UC) luminescence nanoparticles have been prepared using co-precipitation and hydrothermal techniques, respectively. Two different fluoride sources were used to synthesize BYF by the hydrothermal method, and the sizes of the as-prepared spherical particles were about 30 nm (NH 4 BF 4 as a fluoride source) and 100 nm (NH 4 HF 2 as a fluoride source), respectively. While the nanoparticles prepared by the co-precipitation method are irregular, many clusters and agglomerates can be seen. The UC fluorescence has been realized in all the as-prepared BYF samples upon 980 nm excitation. It is found that their luminescence spectra depend strongly upon the preparation method. Factors affecting the upconversion fluorescent intensity have been also studied. The UC emission transitions for 4 F 9/2 – 4 I 15/2 (red), 2 H 11/2 – 4 I 15/2 (green) and 4 S 3/2 – 4 I 15/2 (green) in the Yb 3+ /Er 3+ codoped BYF nanoparticles depending on pumping power have also been discussed. Keywords Upconversion Fluoride source Co-precipitation technique Hydrothermal synthesis 1 Introduction Rare-earth (RE) doped nano-structured materials have attracted great interests in recent years due to luminescent properties induced by their nano-scale sizes with potential applications in the field of solid state luminescence [1–5] . Owing to high quantum efficiency and lower phonon energies, fluorides doped with RE ions are very attractive materials for optical applications, which are relatively stable in air and different from chloride or bromide hosts [6–8] . Among the RE ions, the Er 3+ ion is suitable for converting infrared (IR) to the visible light through the upconversion (UC) process due to its proper electronic energy level scheme. The co-doping of the Yb 3+ ion (a sensitizer) with the Er 3+ ion can remarkably enhance the UC efficiency from infrared to visible lights due to the efficient energy transfer from Yb 3+ to Er 3+ [9–12] . Recently, many reports are focused on the modification of nano- to micro-sized fluoride phosphors, which involve selected solvent treatment, ligands and surfactants to control the size and morphology of the products. For example, Bu et al. synthesized novel Ba 2 ErF 7 and Yb 3+ -doped Ba 2 ErF 7 powder by a co-precipitation method [13] . Chen et al. reported on the comparative investigation of structure and luminescence properties of tetragonal LiYF 4 and BaYF 5 , and hexagonal NaYF 4 phosphors codoped with Er 3+ /Yb 3+ by a facile hydrothermal synthesis [14] . Furthermore, BaYF 5 in nanoscale is an ideal host for the Yb 3+ /Tm 3+ co-dopants [15] , nevertheless a correlation between the synthesized phases and the luminescence behaviors is not clearly verified. Based on this, BaYF 5 can be used as a kind of ideal host for UC materials, and some researches on the shape- and size-dependent UC luminescent behavior of BaYF 5 are expected. In the present work, the structure and upconversion luminescence properties of Yb 3+ /Er 3+ co-doped BaYF 5 samples prepared by different techniques have been studied. The particle sizes and the differences of upconversion spectra behavior between co-precipitation and hydrothermal techniques are described in detail. 2 Experimental 2.1 Synthesis Yb 3+ /Er 3+ codoped BaYF 5 nanoparticles were prepared using co-precipitation and hydrothermal techniques, respectively, and the samples were named as c-BYF and h-BYF in the following section. All the BYF samples were co-doped with 20 mol% of Yb 3+ and 6 mol% of Er 3+ with respect to the alkali-earth metal ions. Analytical grade Er 2 O 3 , Yb 2 O 3 , and Y 2 O 3 were separately dissolved in dilute HNO 3 to prepare the 0.2 mol/L stock solutions of Er(NO 3 ) 3 , Yb(NO 3 ) 3 , and Y(NO 3 ) 3 . NH 4 HF 2 and NH 4 BF 4 were dissolved in deionized water to prepare the 1 mol/L stock solutions. For a typical synthesis of BaYF 5 :20%Yb 3+ /6%Er 3+ nanocrystals, 0.5 mmol of stoichiometric RE(NO 3 ) 3 (0.2 mol/L, RE = Er, Yb, Y; Y:Yb:Er = 78:20:2) aqueous solution and 2 mL of fluoride solution (1 mol/L) were used. 2.1.1 Coprecipitation technique For a typical co-precipitation synthesis procedure, 5 mmol (Ba 2+ , 0.76Y 3+ , 0.06Er 3+ , and 0.2Yb 3+ ) was firstly mixed together, and then the mixture solution was added dropwise into25 mmol F − (NH 4 HF 2 ) ion solution under constant stirring. The obtained precipitate solutions were vigorously stirred at 50 °C for about 2 h. The white precipitate was separated by centrifugation and washed with water for several times, and then dried in a furnace at 100 °C for 24 h to obtain BYF precursors. The precursors were subsequently annealed at 900 °C in air for 4 h to obtain the final product. The as-obtained sample was used for structure and property characterization. 2.1.2 Hydrothermal technique For a typical hydrothermal synthesis procedure, 5 mmol (Ba 2+ , 0.76Y 3+ , 0.06Er 3+ , and 0.2Yb 3+ ) was added in the 25 mL solution of the metal nitrates. Then 25 mmol F − (NH 4 HF 2 /NH 4 BF 4 ) ions should be necessary to precipitate totally metals as the fluoride by the reaction above transparent solution with vigorous stirring continuously for about 20 min. Subsequently, the milky colloidal solution was transferred to a 40 mL Teflon-lined autoclave, and the autoclave was sealed and maintained at 220 °C for 24 h, and then cooled to room temperature naturally. The white precipitate was separated by centrifugation and washed with ethanol for several times, and then dried in a vacuum at 80 °C for 12 h. The as-obtained sample was used for structure and property characterization. 2.2 Characterization Powder X-ray diffraction (XRD) measurements were performed on a Shimadzu XRD-6000 diffractometer at a scanning rate of 2.0° (2 θ )/min from 20° to 85°, with Cu Kα radiation ( λ = 0.15405 nm). Transmission electron microscope (TEM) images were observed using a JEOL-2010 Electron Microscope with an acceleration voltage of 200 kV. Fourier transform infrared spectroscopy (FT-IR) data were collected on a Nicolet 380 spectrophotometer over the range of wavenumber 4000–1500 cm −1 . The photoluminescence (PL) measurements were performed on a HitachiF-4500 spectrophotometer equipped with a 150 W xenon lamp as the excitation source. The UC luminescence emission spectra were obtained on the same HitachiF-4500 spectrophotometer using a 980 nm semiconductor laser (Beijing Viasho Technology Company, China) as the excitation source. All the measurements were performed at room temperature. 3 Results and discussion 3.1 XRD analysis Fig. 1 gives the XRD patterns of the c-BYF samples (a), h-BYF samples using NH 4 BF 4 as a fluoride source (h-BYF/NH 4 BF 4 ) (b), and h-BYF samples using NH 4 HF 2 as a fluoride source (h-BYF/NH 4 HF 2 ) (c), respectively. All characteristic diffraction peaks at 2 θ = 26.3°(1 3 1), 30.38°(3 3 0), 43.55°(1 2 3), 51.37°(0 6 2), 53.80°(2 6 2), 63.09°(3 7 2), 69.79°(0 1 5), 71.42°(1 2 5), and 79.98°(2 7 4) are presented, which are in good agreement with the standard values for the bulk tetragonal BaYF 5 (JCPDS46-0039). On the basis of the above results, we conclude that it cannot change the crystal structure of the products by varying different synthesis procedure and reaction condition. Further, it is found that the diffraction peaks all shift to the higher angles direction owing to the substitution of Er 3+ and Yb 3+ ions for Y 3+ . As a result, the lattice parameters of BaYF 5 :Yb 3+ , Er 3+ were calculated by the UnitCell program [16] in the tetragonal system based on the given XRD data in Fig. 1 a, and it has an tetragonal phase and lattice constants of a C = 12.28 ± 0.07 Å, υ (cell volume) = 1010.99 ± 10.58 Å 3 . 3.2 TEM analysis TEM images were taken in order to estimate the size and evaluate the morphology of the grains of the BYF samples. A series of controlled experiments demonstrated that the shape evolutions of BYF crystals are influenced by external factors such as different methods and fluoride sources in conjunction with the intrinsic crystallographic structure of BYF crystals. Fig. 2 displays TEM images of the as-prepared c-BYF (a), h-BYF/NH 4 BF 4 (b) and h-BYF/NH 4 HF 2 (c). It is suggested that the crucial effects of synthesis conditions and fluoride sources on the crystalline phases and morphologies of the products in our current synthesis. As shown in Fig. 2 a, it is found that the c-BYF grains consist of many clusters and agglomerates, which also has many particles with clearly marked grain boundaries. This result is characteristic of materials prepared at high sintering temperature. Differently from co-precipitation technique, the hydrothermal technique does not require high temperature treatments, avoiding agglomeration and sintering of the grains. Fig. 2 b and c give the TEM images of the samples by hydrothermal method. For each h-BYF product, the grains do not form clusters and agglomerates as they are mostly separated and not sintered. When other reaction conditions remain invariable, the size of the obtained particles is about 100 nm if NH 4 BF 4 is used as a fluoride source. However, NH 4 HF 2 replaced NH 4 BF 4 as the fluoride source, and the mean size of the obtained sample is about 30 nm in diameter ( Fig. 2 c). Meanwhile, the selected area electron diffraction (SAED) pattern for h-BYF/NH 4 HF 2 sample ( Fig. 2 d) demonstrates the highly crystalline nature and confirmed the tetragonal crystalline structure of the h-BYF/NH 4 HF 2 nanoparticles. By comparing the TEM images of the samples, the grain sizes of the BYF products formed under hydrothermal method are more uniform and small than that obtained by the co-precipitation method, meanwhile, the morphologies of the products are quite different from the different fluoride source in the same hydrothermal method. For the hydrothermal method, in aqueous solution, BF 4 − (NH 4 BF 4 as fluoride source) was hydrolyzed to produce BO 3 3− , HF and F − anions, as shown in the following Eq. (1) , and then F − anions react with Ba 2+ , Y 3+ to form BYF shown in Eq. (3) . As a comparison, HF 2 − (NH 4 HF 2 as fluoride source) was directly hydrolyzed to produce HF and F − anions, as shown in the following Eq. (2) , and then F − anions react with Ba 2+ , Y 3+ to form BYF shown in Eq. (3) . It is found that the equilibrium constant of the hydrolysis reaction [Eqs. (1) and (2) ] is different in the present hydrothermal condition, which will induce different morphologies and sizes of the nanoparticles [17] . (1) BF 4 − + 3 H 2 O ↔ H 3 BO 3 + 3 HF + F − (2) HF 2 − ↔ HF + F − (3) Ba 2+ + Y 3+ + 5 F − → BYF ↓ 3.3 IR spectra and optical characterization Fig. 3 presents IR reflectance spectra recorded for as-prepared c-BYF (a), h-BYF/NH 4 BF 4 (b) and h-BYF/NH 4 HF 2 (c). As expected, the as-prepared h-BYF samples contain considerable amounts of water. Meanwhile, the content of water in h-BYF/NH 4 HF 2 (c) is larger than for as-prepared h-BYF/NH 4 BF 4 sample. These are evidenced by the broad band around 3740 cm −1 as well as narrower band observed at 1640 cm −1 , indicative of antisymmetric and symmetric stretches and HOH bending modes [18] . Fig. 4 shows the UC emission spectra of as-prepared c-BYF (a), h-BYF/NH 4 BF 4 (b) and h-BYF/NH 4 HF 2 (c) upon an excitation wavelength of 980 nm, all of which have similar spectra profile corresponding to the same wavelength except for different relative emission intensities. Three intense emission bands centered at 523, 546, and 667 nm corresponding to the transitions of 4 S 3/2 – 4 I 15/2 , 2 H 11/2 – 4 I 15/2 and 4 F 9/2 – 4 I 15/2 , respectively, were simultaneously observed. It can be seen that the upconversion fluorescence intensities of green (523 and 546 nm) and red {667 nm} emissions of Er 3+ are affected by the different methods. The UC intensity of green emission for c-BYF is larger than that of as-prepared h-BYF samples. However, the strongest emission peak occurs at 667 nm in h-BYF/NH 4 HF 2 samples ( Fig. 4 c). Fig. 5 shows the different integrated ratios for the green ( 2 H 11/2 + 4 S 3/2 − 4 I 15/2 ) and red ( 4 F 9/2 − 4 I 15/2 ) upconversion emission based on the different samples. Since the component and crystal structure are the same for c-BYF and h-BYF samples, heat-treatment temperature then becomes the reason for why they have different upconversion spectra. The very large difference in the heat-treatment temperature may have an effect on the amount of the impurity which then affects the luminescence behaviors [19] . The c-BYF samples were heat-treated at 900 °C finally, while the h-BYF samples were heated only at 80 °C. So sample heated at 80 °C will have considerable amount of the water and hydroxyl groups, probably that bounded to the surface of the powder evaporates; however, heating at 900 °C is necessary for complete removing of the stronger bounded hydroxyl groups [20,21] . Thus, the energy in the 4 S 3/2 level for the green emission will be relaxed to the lower 4 F 9/2 level, increasing the red-to-green ratio of the emission. This results from a considerable amount of water and hydroxyl groups present in the fluoride structure, which quenches the emission from the higher positioned levels [22–24] . Therefore, the water and hydroxyl groups can explain why the differences in emission spectra exist between c-BYF and h-BYF. Further, Fig. 6 gives the pumping power dependent upconversion spectra of BYF samples, suggesting that UC emission intensities increased gradually with increasing pumping power. Different UC emission intensities are observed for the three BYF samples. To investigate the fundamental UC mechanism of samples, the right presents the pumping power dependence of 2 H 11/2 ( 4 S 3/2 )– 4 I 15/2 (green) and 4 F 9/2 – 4 I 15/2 (red) transition emissions for as-prepared BYF samples. It is well known that the emission intensity ( I f ) will be proportional to some power ( n ) of the infrared excitation power ( P ) [25] : (4) I f ∝ P n where n is the number of photons required to populate the emitting state. The results are shown in Fig. 6 for different samples. These results show that two-photon process is responsible for green and red emissions to the three BYF samples. The excited states for upconversion can be populated by several well-known mechanisms: (1) excited state absorption (ESA) and (2) energy transfer (ET) [26–28] . Fig. 7 shows the energy level diagram of Er 3+ and Yb 3+ ions as well as the proposed upconversion mechanisms accounting for the green and red emissions under 980 nm laser excitation [29–31] . In the complex Yb 3+ /Er 3+ codoped BYF system, an initial energy transfer from an Yb 3+ ion in the 2 F 5/2 state to an Er 3+ ion populates the 4 I 11/2 level. A second 980 nm photon, or energy transfer from an Yb 3+ ion, can then populate the 4 F 7/2 level of the Er 3+ ion. The Er 3+ ion can then relax nonradiatively to the 2 H 11/2 and 4 S 3/2 levels, and the green 2 H 11/2 – 4 I 15/2 and 4 S 3/2 – 4 I 15/2 emissions occur. Alternatively, the ion can further relax and populate the 4 F 9/2 level leading to the red 4 F 9/2 – 4 I 15/2 emission. The 4 F 9/2 level may also be populated from the 4 I 13/2 level of the Er 3+ ion by absorption of a 980 nm photon, or energy transfer from an Yb 3+ ion, with the 4 I 13/2 state being initially populated via the nonradiative 4 I 11/2 – 4 I 13/2 relaxation [21] . 4 Conclusions BaYF 5 :Yb 3+ , Er 3+ (BYF) materials have been prepared using two different techniques. The size and morphology of the as-prepared particles depend upon the preparation technique. The UC fluorescence has been realized in the as-prepared BYF samples upon 980 nm excitation. The UC emission transitions for both 2 H 11/2 ( 4 S 3/2 )– 4 I 15/2 (green) and 4 F 9/2 – 4 I 15/2 (red) in the BYF:Yb 3+ , Er 3+ samples came from two-photon UC processes. Obvious differences in fluorescent emission spectra between c-BYF and h-BYF powders were observed. The UC intensity of green emission in c-BYF is larger than that of as-prepared h-BYF samples, while the strongest emission peak occurs at 667 nm in h-BYF/NH 4 HF 2 samples. The impurities of water and hydroxyl groups and the surface effect were suggested to account for the upconversion luminescence differences between the c-BYF and the h-BYF materials.

"abstract": "The Yb3+/Er3+/Tm3+-doped Gd 6MoO12 phosphors and Li+/Yb3+/ Er3+/Tm3+-doped Gd6MoO12 phosphors were synthesized by the high-temperature solid-state method. Under 980 nm laser diode excitation, the Gd6MoO12:Li+/Yb 3+/Er3+/Tm3+ phosphors show the white upconversion (UC) emission at the pump power of 200 mW/cm2, which is composed of the blue (1G4→3H6 of Tm3+), green (2H11/2, 4S 3/2→4I15/2 of Er3+), and red (4F9/2→4I15/2 of Er 3+) UC emissions. The calculated CIE color coordinates of Gd 6MoO12:Tm3+/Er3+/Yb3+ phosphors changed from blue area to white area after the Li+ ion doping. Then, the effect of Li+ ions mixing on the emission was analysed. The relative UC mechanisms and properties were also investigated and proposed based on their spectral. The additional mixed Li+ ions enhanced the red and green upconversion emission largely in this phosphor and then formed the white UC emission, which indicated that the Li+ is a promising dopant for tuning white light luminescence in some case. © 2013 Elsevier B.V.

The upconversion luminescence properties of two-ion and three-ion co-doped KGd(WO4)2 phosphors were investigated in detail. The concentration quenching effect of the two-ion co-doped KGd(WO4)2 phosphors was studied, and the optimum concentration of Ho3+, Er3+ and Tm3+ are 2 mol.%, 2 mol.% and 3 mol.%, respectively. The Yb3+/Ho3+/Tm3+ co-doped KGd(WO4)2 sample is the best white upconversion luminescence material among three-ion co-doped KGd(WO4)2 phosphors. The CIE coordinates for the samples were calculated, and chromaticity coordinates were close to white light regions. The upconversion luminescence mechanism of the samples was discussed. The upconver-sion luminescence of Ho3+ and Er3+ was both produced through two-photon process. The emissions of Ho3+ at 546 and 654 nm originated from the transition of Ho3+ (5S2→5I8 and 5F5→5I8), while those of Er3+ at 530 and 551 nm were attributed to the transition of Er3+ (2I11/2→4I15/2 and 4S3/2→ 4I15/2). The upconversion luminescence mechanism of Tm3+ was a three-photon process. The blue emission of Tm3+ was due to the transition of Tm3+ (1G4→3H6).",

"abstract": "The ZBLAN : Nd3+, Tm3+, Yb3+ upconversion materials were prepared by high-temperature solid method. The concentrations of Tm3+ and Yb3+ were 0.01% and 0.3% respectively. The concentration of Nd3+ changed in the range from 0.1% to 2%. The absorption spectrum of ZBLAN : Nd3+, Tm3+, Yb3 in all samples from 300 to 1 000 nm was measured at room temperature. The upconversion emission was observed when excited by 798 nm infrared light. The material samples emitted relatively strong multi-band (the red, blue and green color) visible light. Based on the experiment, the multi-band visible spectral lines were analyzed, and the energy level transition mechanism was given. The blue light results from the transition of 1G4 --> 3 H6 of Tm3+, the green light is from the transition of 2 H7/2 --> 4 I9/2 of Nd3+, and the red light originates from the transition of 2 H11/2 --> I9/2 of Nd3+. The results show that the upconversion mechanism includes excited state absorption, energy transfer, cross relaxation and so on. The energy transfer processes between Nd3+, Tm3+ and Yb3+ ions both forward and backward prove to be the origin of upconversion emissions. The effect of rare earth doping concentration on the energy upconversion efficiency was analyzed, according to the different upconversion light emitting intensity from samples with different Tm3+ mol concentrations. The upconversion luminescence increased with the Nd3+ concentration and got its peak at 1.5%.",

"title": "Luminescence of Eu2+ in alkali earth chlorosilicate phosphor and their color-tunable properties",
"abstract": "Alkali earth chlorosilicate of the types Sr 4− x Mg x Si 3 O 8 Cl 4 :Eu 2+ and Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ have been synthesized from mixtures of SrCO 3 , CaCO 3 , SrCl 2 · 6H 2 O, SiO 2 , MgO, Eu 2 O 3 and proper fluxing agent selected from NH 4 Cl and H 3 BO 3 , which were fired at 900–1000 °C for 2–4 h, and carbon powder was used as a reducing agent. According to the Van Uitert experimental equation, the color-tunable photoluminescence properties and crystal-lattice environment of Eu 2+ in the host lattice have been studied. Depending on the ratio of Sr 2+ and other alkali earth ions (Mg 2+ or Ca 2+ ) in the host, the position and intensity of different luminescence centers are influenced by Eu 2+ located at different chemical environmental sites. Owing to this, it shows from blue-violet (411 nm) to greenish-yellow (565 nm) luminescence under 365nm ultraviolet radiation. Keywords Optical materials Chlorosilicate Color-tunable Spectra Luminescence 1 Introduction Chlorosilicate crystal material is a suitable host lattice for luminescence materials. Alkali earth halide and silicate compound are both effective host as the Eu 2+ luminescence matrices. As the multiplex compound, alkali earth chlorosilicate crystal has lower synthesis temperature and higher physical chemistry stability [1–3] . In the chlorosilicate host, the luminescence of Eu 2+ consists of a 4f 6 5d 1 –4f 7 ( 8 S 7/2 ) broad-band emission, which belongs to electric-dipole allowed transition and has the properties of large absorption of UV light and broad emission range from ultraviolet to infrared light depending on different crystal-lattice environment [4] . In this paper, a series of color-tunable photoluminescence materials having the chemical formula as Sr 4− x Mg x Si 3 O 8 Cl 4 :Eu 2+ ( x = 0, 0.5, 1.0, 1.5) and Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ ( x = 0.2, 0.4, 0.6, 1.0, 1.5, 2.0) are synthesized through the high temperature solid state method. By analyzing the excitation and emission spectra, the luminescence mechanism of Eu 2+ in this kind of host lattice are discussed. And the relationship of material structure with the luminescence properties is also studied. This series of materials are promising to be used for light emitting diodes (LEDs) and will promote the development of the application in luminescence and display fields. 2 Experimental Through the high-temperature solid state synthesis method, a series of powder samples of (Sr, Mg) 4 Si 3 O 8 Cl 4 :Eu 2+ and (Sr, Ca) 4 Si 3 O 8 Cl 4 :Eu 2+ were prepared respectively by firing intimate mixtures of high-purity SrCO 3 (A.R.), CaCO 3 (A.R.), SrCl 2 · 6H 2 O (A.R), SiO 2 (A.R.), MgO(A.R.), Eu 2 O 3 (99.999%) and proper flux selected from NH 4 Cl(A.R) and H 3 BO 3 (A.R). All starting materials were weight in the proper stoichiometries, and mixed in an agate mortar, then placed in corundum crucibles. The samples were fired at 900–1000 °C for 2–4 h, and carbon powder was used as a reducing agent, by which the samples were covered during firing ( Table 1 ). The X-ray diffraction patterns of the samples were recorded by using SHIMADZU model XRD-6000 X-ray powder diffractometer (Cu Kα radiation, 40 kV, 30 mA and a scanning speed 2.0°/min). All excitation and emission spectra were recorded by using HITACHI model F-4500 fluorescence spectrophotometer with a 400 V photomultiplier tube and a 150 W Xe lamp. 3 Results and discussion 3.1 Phase composition of the obtained phosphors JCPDS file 40-0074 supplies the X-ray diffraction data for Sr 4 Si 3 O 8 Cl 4 , and XRD pattern of the Sr 4 Si 3 O 8 Cl 4 :Eu 2+ sample is shown in Fig. 1 . With careful comparison between file 40-0074 of Sr 4 Si 3 O 8 Cl 4 and the sample of Sr 4 Si 3 O 8 Cl 4 :Eu 2+ , the position and intensity of the main peaks are nearly the same. It also indicates that the crystal lattice and basic structure of the Sr 4 Si 3 O 8 Cl 4 host can obtained successfully by the traditional high temperature solid state method. By adding Mg 2+ or Ca 2+ to the host lattice, Sr 4− x Mg x Si 3 O 8 Cl 4 :Eu 2+ and Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ phosphors are synthesized with the increase of amount of the magnesium or calcium which replaced the strontium. 3.2 Luminescence of Eu 2+ in Sr 4 Si 3 O 8 Cl 4 host lattice The excitation spectra of Sr 4 Si 3 O 8 Cl 4 :Eu 2+ show characteristic excitation spectra band of Eu 2+ ion, which is broad in the range from 250 nm to 400 nm. As seen in Fig. 2 , it gives the excitation and emission spectra of Sr 4 Si 3 O 8 Cl 4 :Eu 2+ . Under 365 nm UV light, Sr 4 Si 3 O 8 Cl 4 :Eu 2+ shows broad emission, related to the 5d–4f transition, and gives a strong blue-green luminescence with peak wavelength at 496 nm and FWHM 70 nm. But as shown in Fig. 2 , the emission spectra has some appreciable asymmetry, the possible reason is that the excitation and emission spectra overlap each other. So it results in the self-absorption of the sample’s short wavelength side. Nevertheless, the sample possibly has only one emission center, that is to say that the coordinating environments for all Eu 2+ are the same, thus, the luminescent emission shows only one broad peak [2] . According to the report of Van Uitert [5] , for most divalent and some trivalent rare earth ions in suitable matrices, such as sulfide, oxide, halide and aluminates, the following experiential equation provides a good fit to the emission peak and excitation edge data for Eu 2+ and Ce 3+ . Based on this, the problem about which kind of crystallographic site substituted by Eu 2+ in the Sr 4 Si 3 O 8 Cl 4 host lattice is discussed and testified. (1) E = Q 1 - ( V / 4 ) 1 / V 10 - ( near ) / 80 In the above Eq. (1) , E represents the position of the d-band edge in energy for rare earth ions (cm −1 ), Q is the position in energy for the lower d-band edge for the free ions, value of Q is 34,000 cm −1 for Eu 2+ , V is the valence of the “active” cation, here V = 2. ‘ea’ is the electron affinity of the atoms that form anions, ea is regarded as 2.19 eV in Sr 4 Si 3 O 8 Cl 4 host. n is the number of anions in the immediate shell about this ion, and r is the radius of the host cation replaced by the “active” cation. It is reported that Sr is coordinated by four O atoms and four Cl atoms in the Sr 4 Si 3 O 8 Cl 4 host and the sites of Sr 2+ will substitute by Eu 2+ in the Sr 4 Si 3 O 8 Cl 4 :Eu 2+ phosphor, whichever factor like radius and charge are considered [2] . So the value of coordination number n of Eu 2+ is eight, and the radius of Sr 2+ under this coordination environment is 0.126 nm. Through the above data, it can be calculated that there is only one octa-coordination Sr 2+ sites in the host lattice and the Eu 2+ center that shows blue-green luminescence really comes from octa-coordination Sr 2+ site [6] . 3.3 Luminescence properties of (Sr, Mg) 4 Si 3 O 8 Cl 4 :Eu 2+ phosphor By changing the dopant amount of Mg 2+ ions, a series of powder materials represented by the chemical formula Sr 4 Si 3 O 8 Cl 4 :Eu 2+ , Sr 3.5 Mg 0.5 Si 3 O 8 Cl 4 :Eu 2+ , Sr 3.0 MgSi 3 O 8 Cl 4 :Eu 2+ and Sr 2.5 Mg 1.5 Si 3 O 8 Cl 4 :Eu 2+ were successfully synthesized under the condition of invariable dopant concentration of Eu 2+ in the host lattice. As mentioned above, all the excitation spectra of the materials show characteristic excitation spectra band of Eu 2+ ion, which is broad in the range from 250 nm to 400 nm. The emission spectra of them are shown in Fig. 3 . And Table 2 gives the respective center position of different Sr 4− x Mg x Si 3 O 8 Cl 4 : Eu 2+ phosphors. According to the experimental equation of Van Uitert, the theoretical value of Eu 2+ luminescence center that substituted the octa-coordination Sr 2+ site is 471 nm. So we can conclude that the Eu 2+ center that shows blue-green luminescence really comes from octa-coordination Sr 2+ site, and signed it as Sr (A) site. While considering the emission peak that shows blue-violet luminescence, it arises from the dopant of Mg 2+ in the host lattice, and its emission intensity increases remarkably with the concentration of Mg 2+ increasing as seen from the Fig. 3 . This indicates that the Eu 2+ center that shows blue-violet luminescence here originates from a completely different site substitution from the former, and we can consider it as Sr (B) site. The correlative data can be seen form the emission peak (B) in the Table 2 , which is obviously different from theoretical calculated value of Eu 2+ center occupied octa-coordination Sr 2+ site. From the above spectroscopic analysis, we can conclude that there are two different property cation sites in the host lattice because of the dopant of Mg 2+ . The possible reason is that the large size difference between Mg 2+ and Sr 2+ , and it results in the distortion of host lattice to some certain extent. But simultaneously we notice that the framework of Sr 4 Si 3 O 8 Cl 4 can hardly change completely by the introduction of impurity ions owing to cation replacement. Therefore, the coordination numbers of cation ions whatever Sr (A) site or Sr (B) site are invariably eight as likely as not, and the substitution process can hardly produce other new coordination numbers in the host lattice because of similar physical chemistry properties between Sr 2+ and Mg 2+ . So we consider that the different luminescence peaks are not aroused by the luminescence centers of Eu 2+ located in the sites possessing different coordination numbers, and the two different luminescence centers of Eu 2+ should be ascribed to their respective crystal-lattice environment [6] . 3.4 Luminescence properties of (Sr,Ca) 4 Si 3 O 8 Cl 4 :Eu 2+ phosphor Different from the Eu 2+ luminescence in Sr 4− x Mg x Si 3 O 8 Cl 4 host, the following experimental conclusion indicate that the emission peak of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ change irregularly depending on the ratio of Sr 2+ and Ca 2+ in the host lattice. When the doping amount of calcium ( x ) ranged from 0 to 0.5, the sample shows blue-green emission as seen in Fig. 4 . And the respective center position for the different compositions of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ is listed in Table 3 . Obviously, the spectra properties of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ does not differ largely from Sr 4 Si 3 O 8 Cl 4 :Eu 2+ . Its emission peak does not change to some extent except for the decrease of the luminescence intensity. Considering the small dopant amount of Ca 2+ , similar radius difference and physical chemical property between Ca 2+ and Sr 2+ , it is possible that Ca 2+ ions are embedded in the host lattice of Sr 4 Si 3 O 8 Cl 4 and substitute the Sr 2+ sites partly; finally they form solid dissolved system among definite component range. So Eu 2+ will mainly substitute the octa-coordination Sr 2+ sites, and show blue-green luminescence. It is obvious that the luminescence of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ that x ranged from 0 to 0.5 is similar to the above discussion about Sr 4− x Mg x Si 3 O 8 Cl 4 :Eu 2+ . On the other hand, Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ shows greenish-yellow luminescence when the range of x is between 0.5 and 2. The emission spectra of them are shown in Fig. 5 . The relationships of the main emission peaks and compositions are given in Table 4 . As shown in Fig. 5 and Table 4 , we find that Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ ( x > 0.5) phosphor show obvious emission peak in the long wavelength side, while the emission peak in the short wavelength side become even invisible. But on an energy scale, the emission bands of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ ranging from 0.5 to 2.0 appear to be asymmetric, and each of them can be divided into two Gaussian bands. For example, as seen in Fig. 6 , the emission spectrum of Sr 2 Ca 2 Si 3 O 8 Cl 4 :Eu 2+ is divided into two Gaussian bands with maxima at 467 and 565 nm. We proposed that there are two different emission center in the host lattice of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ . The emission center in the short wavelength side is signed as Eu (A), and Eu (B) is the center in the long wavelength side. Table 5 shows the respective position of Eu (A) and Eu (B) emission centers that obtained from Gaussian fit of different compositive samples of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ ( x > 0.5). Even as the above discussion, the theoretical value of Eu 2+ luminescence center that substituted the octa-coordination Sr 2+ site is 471 nm. And Eu (A) is mostly probably ascribed to Eu 2+ ions that substituted the octa-coordination Sr 2+ sites. Obviously, the measured position of emission peak is the same as the calculated values by Van Uitert experimental equation. Owing to the same reason as the former, the forming of Eu (B) emission can’t be explained by the existing of other coordination number cations in the host lattice. Eu (B) emission is at long wavelengths, which is similar to what has been observed in BaF 2 :Eu 2+ [7] . This is due to the fact that the Eu 2+ emission originated from the formation of an impurity-trapped exciton state. Eu (B) emission center is located in the impurity-trapped exciton state, which is the lowest excited state of this system. The reason is that chlorosilicate compounds have not only the properties of silicate compound, but also that of alkali earth halide. Along with the substantive adding of Ca 2+ , it gradually shortens the distance of M 2+ (Sr 2+ or Ca 2+ ) and halide ions, also including other anion ions in the system, because of the smaller radius of Ca 2+ . At the same time, it also accelerates the formation of impurity-trapped exciton state as the dopant amount of Ca 2+ is beyond 0.5. A model for the luminescence of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ ( x > 0.5) phosphors can be given in terms of configuration coordinate diagrams as shown in Fig. 7 . From it, curve G represents the ground state; and relative to the original localized excited state L, the impurity-trapped exciton state E has lower energy. By the direct UV radiation, the photon located at the ground state G is excited to the localized excited state L, and then relaxed to the impurity-trapped exciton state E in terms of the crossing F. When the optical transition happens between curve E and G, Eu 2+ emission is at long wavelengths and a large Stokes shift is observed [7] . 4 Conclusion Sr 4− x Mg x Si 3 O 8 Cl 4 ( x = 0, 0.5, 1.0, 1.5) and Sr 4− x Ca x Si 3 O 8 Cl 4 ( x = 0.2, 0.4, 0.6, 1.0, 1.5, 2.0) samples were prepared by the high-temperature solid-state reaction. Based on its excitation and emission spectra of Sr 4− x Mg x Si 3 O 8 Cl 4 :Eu 2+ phosphors, the possibilities of two Eu 2+ emission centers is found and the emission peak shifts from blue-green to blue-violet with the increase of amount of the magnesium which replaces the strontium. Depending on the ratio of Sr 2+ and Ca 2+ in the host lattice of Sr 4− x Ca x Si 3 O 8 Cl 4 :Eu 2+ , the intensity of two Eu 2+ emission centers, viz, Eu (A) and Eu(B), changes irregularly and the corresponding relationships with spectra are also discussed. Eu (A) emission center, which has emission peak located at 496 nm, is ascribed to Eu 2+ ions that substituted the octa-coordination Sr 2+ sites, and Eu (B) emission is in the long wavelength range, which is due to the fact that the Eu 2+ emission originated from the formation of an impurity-trapped exciton state. Owing to their color-tunable photoluminescence properties, this insight can be extremely important for understanding the optical properties of rare-earth materials and for guiding the development of materials for applications.

The photoluminescent properties of Ce 3 and Tb 3 co-doped BaAl 2B 2O 7 phosphors were investigated by using the photoluminescence emission and excitation spectra. Under the excitation of near ultraviolet (n-UV) light, BaAl 2B 2O 7:Ce 3,Tb 3 phosphors exhibited blue emission corresponding to the f-d transition of Ce 3 ions and green emission bands corresponding to the f-f transition of Tb 3 ions, respectively. Effective energy transfer occurred from Ce 3 to Tb 3 in BaAl 2B 2O 7 host due to the observed spectra overlap between the emission spectrum of Ce 3 ion and the excitation spectrum of Tb 3 ion. The energy transfer efficiency from Ce 3 ion to Tb 3 ion was also calculated to be 71%. Furthermore, the concentration quenching and critical distance of BaAl 2B 2O 7:Ce 3,Tb 3 phosphors were also discussed. The energy transfer from Ce 3 to Tb 3 in BaAl 2B 2O 7 host was demonstrated to be resonant type via a dipole-dipole interaction mechanism with the energy transfer critical distance of 16.13 Å. © 2012 Elsevier B.V.

"abstract": "Synthesis and upconversion luminescence properties of the new BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ phosphor were reported in this paper. The phosphor powder was obtained by the traditional high temperature solid-state method, and its phase structure was characterized by the XRD pattern. Based on the upconversion luminescence properties studies, it is found that, under 980 nm semiconductor laser excitation, BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ phosphor exhibits intense green upconversion luminescence, which is ascribed to 2 H 11/2 → 4 I 15/2 and 4 S 3/2 → 4 I 15/2 transition of Er 3+ . While the observed much weaker red emission is due to the non-radiative relaxation process of 4 S 3/2 → 4 F 9/2 and 4 F 9/2 → 4 I 15/2 transition originating from the same Er 3+ . The concentration quenching effects for both Yb 3+ and Er 3+ were found, and the optimum doping concentrations of 0.5 mol% Yb 3+ and 0.08 mol% Er 3+ in the new BaGd 2 (MoO 4 ) 4 Gd 3+ host were established. Keywords A. Optical materials C. X-ray diffraction D. Optical properties 1 Introduction In recent years, much attention has been paid to the research on rare earth ion doped upconversion luminescence materials due to their application in the field of high power laser diodes. Moreover, they have found applications in many advanced technology fields, such as coherent laser light sources [1] , three-dimensional display [2] , anti-counterfeiting [3] , bioassay [4] , and so on. The double molybdate and tungstate crystals with general formula MRe(XO 4 ) 2 (M = Li, Na, K; X = W, Mo) have been reported as good host materials for solid-state lasers [5,6] . The crystallographic structures of these compounds belong to the scheelite structure of CaWO 4 [7] . Therefore, the luminescence properties of these compounds, such as Nd 3+ :NaLa(MoO 4 ) 2 [8] , Nd 3+ :KLa(MoO 4 ) 2 [9] , Nd 3+ :NaGd(MoO 4 ) 2 [10] and Ho 3+ ,Yb 3+ :KLa(WO 4 ) 2 [11] have been widely studied as the excellent laser materials. In this paper, the selected BaGd 2 (MoO 4 ) 4 compound belongs to a member of double barium lanthanide molybdates BaLn 2 (MoO 4 ) 4 (Ln = Y, La-Lu) [12,13] , and it may be suitable host material for designing the new upconversion luminescence materials. Therefore, the synthesis and upconversion luminescence properties investigation on Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 powder were reported, and the possible upconversion luminescence mechanism is also discussed. 2 Experimental Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 powder samples were prepared by the traditional high-temperature solid-state reaction. The starting materials were BaCO 3 (A.R.), MoO 3 (A.R.), Gd 2 O 3 (99.99%), Yb 2 O 3 (99.99%), Er 2 O 3 (99.99%). The mixture ratio of the reactants was as follows: (1 − x − y ) Gd 2 O 3 + BaCO 3 + 4MoO 3 + x Yb 2 O 3 + y Er 2 O 3 ( x = 0.2, 0.25, 0.3 and 0.35; y = 0.03, 0.04, 0.05 and 0.06). The weighed raw materials were thoroughly mixed in an agate mortar and then placed in a corundum crucible with a lid. Then, the samples were sintered at 1000 °C for 4 h in air. The phase structure of the as-synthesized Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 powders were determined by X-ray powder diffraction spectroscopy (XRD, using a Shimadzu XRD-6000) operating at Cu Kα radiation, 40 kV, 30 mA, and a scan speed of 2.0° (2 θ )/min. The upconversion luminescence spectra were recorded on a Hitachi F-4500 spectrophotometer equipped with an external power-controllable 980 nm semiconductor laser (Beijing Viasho Technology Company, China) as the excitation source, which is connected with an optic fiber accessory. 3 Result and discussion We have carefully prepared our samples and checked their phase structures. As seen in Fig. 1 , it shows the XRD patterns of the pure BaGd 2 (MoO 4 ) 4 (a) and Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 phosphor powder (b), and the JCPDS Card No. 36-0192 (c). By careful comparison among the given XRD patterns, their positions and intensities of the main peaks are nearly the same. It indicates that the crystal structure of the as-synthesized pure BaGd 2 (MoO 4 ) 4 and Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 phosphor powder are in good agreement with the standard value from the JCPDS files of BaGd 2 (MoO 4 ) 4 , which means that the crystal lattice and basic structure of the BaGd 2 (MoO 4 ) 4 host can be obtained successfully by the high-temperature solid-state method. Further, it also testifies that the crystal structure of BaGd 2 (MoO 4 ) 4 had no obvious change after codoping Yb 3+ and Er 3+ ions. Under 980 nm semiconductor laser excitation, the upconversion luminescence properties of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ with different doping concentration of Yb 3+ and Er 3+ are comparatively investigated in detail. Fig. 2 gives the upconversion luminescence spectra of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ phosphor for different Yb 3+ concentration and invariable Er 3+ concentration (0.06 mol%). As seen in Fig. 2 , two peaks at 532 nm and 553 nm of intense green emissions attributed to the transition emission of Er 3+ ( 2 H 11/2 → 4 I 15/2 and 4 S 3/2 → 4 I 15/2 ) are observed. As seen in the inset of Fig. 2 , it shows the enlarged spectra in the red emission region. The much weaker red emission at 656 nm due to the transition 4 F 9/2 → 4 I 15/2 of Er 3+ can be also seen detected by the instrument, but not observed by the naked eye. With increasing Yb 3+ concentration, the emission intensity increases, maximizes at 0.5 mol% Yb 3+ concentration, and then decreases. It also indicates that the optimum Yb 3+ concentration should be 0.5 mol%. Similarly, as seen in Fig. 3 , it shows the upconversion luminescence spectra of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ phosphor under 980 nm semiconductor laser excitation for different Er 3+ concentration and invariable Yb 3+ concentration (0.5 mol%). The same strong green emission peaks at 532 nm and 553 nm are observed, and concentration dependence of emission intensities is also seen in Fig. 3 . With increasing Er 3+ concentration, the emission intensity increases, maximizes at 0.08 mol% Er 3+ concentration, and then decreases. Accordingly, the variation of red emission region (from 640 nm to 680 nm) agree with the variation tendency former green emission peaks, as given in the inset of Fig. 3 . It further indicates that the optimum Er 3+ concentration should be 0.08 mol%. Therefore, the optimum doping concentrations 0.5 mol% Yb 3+ and 0.08 mol% Er 3+ in the new BaGd 2 (MoO 4 ) 4 Gd 3+ host are established, and a concentration quench effect extends beyond the given region. Upconversion visible emissions are produced through multiple process including ground-state absorption (GSA) and energy transfer (ET). For Yb 3+ /Er 3+ codoped upconversion phosphors, Yb 3+ ion is usually used as a sensitizing ion to increase the upconversion luminescence intensities of the Er 3+ ion, due to the energy matching of the gap (between 2 F 7/2 and 2 F 5/2 ) of Yb 3+ [5] . The possible green upconversion luminescence mechanism is shown in Fig. 4 . A Yb 3+ ion is excited by a 980 nm photon from ground state ( 2 F 7/2 ) to the excited-state ( 2 F 5/2 ) through GSA process, and then transfers the energy to a Er 3+ ion and promotes it from 4 I 15/2 to 4 I 11/2 . Another Yb 3+ ion at 2 F 5/2 level continuously transfers the energy to the excited Er 3+ ion, then the Er 3+ ion transits to a higher level at 4 F 7/2 . The populated level 4 F 7/2 decays non-radiatively to 2 H 11/2 and 4 S 3/2 , finally produces green emissions at 532 nm and 553 nm with a radiative transition to ground state 4 I 15/2 , respectively. It can be concluded that the occurrence of green upconversion luminescence can be attributed to a two-photon process. As seen in the spectra diagram of Figs. 2 and 3 , the red emission of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ is much weaker than the green one. It is so weak that it can hardly be observed from the upconversion luminescence spectra except for the enlarged spectra profiles. The possible explanation is based on the following fact that the red light is produced through the non-radiative relaxation 4 S 3/2 → 4 F 9/2 and the transition 4 F 9/2 → 4 I 15/2 . In this case, the intensities of red upconversion luminescence would be much lower. Further, in order to understand the involved mechanism, the dependence of upconversion luminescence intensity upon the pump power of laser diode is given in Fig. 5 . The relationship between them can be approximately expressed as follows: I out − ( I exc ) n , where n is the number of infrared photons absorbed for emitting a visible photon. In the double-log coordinate, the slope of I out − I exc indicates the value of n , which is used for the deduction of the possible upconversion luminescence process. As given in Fig. 5 , the values of n for green emissions at 532 nm and 553 nm are 1.77 and 1.74, respectively, while that of red emission at 656 nm is 0.69. The results indicate that green emission originated from a two photon process, and the weak red emission should come from the non-radiative relaxation of 4 S 3/2 → 4 F 9/2 . 4 Conclusion A new green upconversion luminescence phosphor powder BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ has been synthesized by high-temperature solid-state method. The pure phase structure of the phosphor is characterized by XRD. It can be observed in the upconversion spectra of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ that the red emission is much weaker than that of green one. The green emission is a two photon processes, while the red light is due to the non-radiative relaxation of Er 3+ ( 4 S 3/2 ) → Er 3+ ( 4 F 9/2 ) and the transition Er 3+ ( 4 F 9/2 ) → Er 3+ ( 4 I 15/2 ). The concentration quenching effects for both Yb 3+ and Er 3+ were found, and the optimum doping concentration of 0.5 mol% Yb 3+ and 0.08 mol% Er 3+ in the new BaGd 2 (MoO 4 ) 4 host are established.

"abstract": "Eu 3+, Er 3+ and Yb 3+ co-doped BaGd 2(MoO 4) 4 two-color emission phosphor was synthesized by the high temperature solid-state method. The structure of the sample was characterized by XRD, and its luminescence properties were investigated in detail. Under the excitation of 395 nm ultraviolet light, the BaGd 2(MoO 4) 4:Eu 3+,Er 3+,Yb 3+ phosphor emitted an intense red light at 595 and 614 nm, which can be attributed to 5D 0 → 7F 1 and 5D 0 → 7F 2 transitions of Eu 3+, respectively. The phosphor will also show bright green light under 980 nm infrared light excitation. The green emission peaks centred at 529 and 552 nm, were attributed to 4H 11/2 → 4I 15/2 and 4S 3/2 → 4I 15/2 transitions of Er 3+, respectively. It indicated that the two-color emission can be achieved from the same BaGd 2(MoO 4) 4:Eu 3+,Er 3+,Yb 3+ host system based on the different pumping source, 395 nm UV light and 980 nm infrared light, respectively. The obtained results showed that this kind of phosphor may be potential in the field of multi-color fluorescence imaging and anti-counterfeiting. © 2011 Published by Elsevier Ltd.",

Effective energy transfer occurs from Ce 3 to Tb 3 in NaBaPO 4 host due to the observed spectral overlap between the emission band of Ce 3 and the excitation band of Tb 3, and the obvious emission bands (354 nm, 489 nm and 542 nm) were ascribed to Ce 3 and Tb 3 ions emission, respectively. We have also shown that the energy transfer from Ce 3 and Tb 3 in NaBaPO 4 host was demonstrated to be resonant type via a dipole-dipole interaction mechanism with the energy transfer critical distance of 1.67 nm. © 2011 The Electrochemical Society.",

The size and shape of the NCs were controlled by adjusting the amount of NaOH, reaction temperature and time. Well oil-dispersible NCs exhibited bright UC fluorescence under the 980 nm excitation. Furthermore, a systematic study on the photoluminescence of Yb3+/Er3+-doped BaYF5 samples with different size and shapes indicated that the optical properties of products were strongly dependent on their size, and the configuration of nanocrystals were found to sensibly affect the optical properties of the products. Great enhancement of the green emission intensity was observed with increasing crystalline size. It was found that the crystalline and surface effects could be responsible for the observation and this behavior was attributed to a change of conditions and the quenching effect of the organic ligands. © 2010 Elsevier B.V.

"abstract": "A series of new red-emitting BaCa1-2xBO3F:xEu 3+, xM+ (M=Li, Na, K) phosphors were synthesized by the solid-reaction method. X-ray diffraction (XRD), diffuse reflection (UV-vis) and photoluminescence spectra were utilized to characterize the crystallization process, structure and luminescence properties of the as-synthesized phosphors. The XRD results indicated that the sample began to crystallize at 800 °C, and single-phase BaCaBO3F was fully obtained after annealing at 1000 °C. The charge compensated behaviors were investigated in this paper by considering different cations like Li+, Na+ and K + acting as the charge compensator. The as-prepared phosphors had better emission properties, and the two characteristic emission lines peaking at 590 and 615 nm could be obtained upon 394, 463 and 532 nm excitation with the chromaticity coordinates of (0.596, 0.391), which were due to 5D 0-7F1 and 5D0- 7F2 transitions of Eu3+ ions. Further, the concentration quenching and corresponding luminescence mechanisms of BaCa 1-2xBO3F:xEu3+, xNa+ phosphors were also discussed. © 2011 The Chinese Society of Rare Earths.",

"abstract": "Yb3+/Er3+ co-doped Gd6MoO12 and Yb3+/Er3+/Li+ tri-doped Gd6MoO 12 phosphors were prepared by adjusting the annealing temperature via the high temperature solid-state method. Under the excitation of 980 nm semiconductor, the upconversion luminescence properties were investigated and discussed. In the experimental process, we get the optimum Yb3+ concentration and the concentration quench effect will happen while the concentration extends the given region. According to the Yb3+ concentration quenching effects, the critical distance between Yb3+ ions had been calculated. The measured UC luminescence exhibited a strong red emission near 660 nm and green emission at 530 nm and 550 nm, which are due to the transitions of Er3+(4F9/2, 2H11/2, 4S3/2) → Er 3+(4I15/2). Then the effect of excitation power density in different regions on the upconversion mechanisms was investigated and the calculated results demonstrate that the green and red upconversion is a two-photon process. A possible mechanism was discussed. After Li+ ions mixing, the upconversion emission enhanced largely, and the optimum Li + concentration was obtained while fixed the Yb3+ and Er3+ on the above optimum concentration. This enhancement owns to the decrease of the local symmetry around Er3+ after Li+ ions doping into the system. This result indicates that Li+ is a promising candidate for improving luminescence in some case. © 2013 Elsevier B.V. All rights reserved.",

"abstract": "Eu 3+ doped NaLa(MoO 4) 2 microcrystals with different sizes are synthesized by a mild hydrothermal method, and the morphologies of the microcrystals can be easily controlled by adjusting the volume ratio of ethylene glycol to water and the aging time. Uniform high-quality shuttle-like microcrystals with an average length of 2.0 μm are obtained under the hydrothermal condition of 180°C for 16 h. From the emission spectra of NaLa(MoO 4) 2:Eu 3+ microcrystals, it is concluded that the dopant Eu 3+ ion occupies a La 3+ site. It is indicated that the concentration quenching of the emission peak at 613 nm of Eu 3+ is ascribed to the electric dipole-electric quadrupole interaction, and the cross relaxation process of Eu 3+( 5D 1) + Eu 3+( 7F 0) →Eu 3+( 5D 0) + Eu 3+( 7F 3) appear. © Chinese Physical Society.",

"abstract": "Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 phosphor powders were prepared by the Sol–gel method and the upconversion luminescence properties were investigated in detail. Under 980 nm semiconductor laser excitation, BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ phosphor exhibits green upconversion luminescence with peaks at 530 and 550 nm, which are due to the transitions of Er 3+ ( 2 H 11/2 ) → Er 3+ ( 4 I 15/2 ) and Er 3+ ( 4 S 3/2 ) → Er 3+ ( 4 I 15/2 ), respectively. Both of the two green emission lines are produced by populating Er 3+ ions to the excited state through a two-photon process. By monitoring the intensities of the green upconversion luminescence, the optimum conditions for the Sol–gel synthesis were determined when the molar ratio of citric acid to total chelate metal cations was 2:1 and the sintering temperature was at 1073 K. The concentration quenching effect for Er 3+ was found at the optimum doping concentration of 6 mol%, and the critical distance for the neighboring Er 3+ was determined to be about 21.5 Å. Keywords Upconversion luminescence Optical properties Sol–gel synthesis 1 Introduction Recently, the researches on rare earth ions doped upconversion luminescence (UL) materials have received a considerable attention because of their applications in many advanced technology fields, such as three-dimensional display [1] , photonics [2] , upconversion luminescence lasers [3,4] , temperature sensors [5] , DNA detection [6] and biological analyses as biolabels [7,8] , and so on. In order to fulfill the corresponding requirements in various application fields, many research papers on developing new UL materials systems have been reported. The selected BaGd 2 (MoO 4 ) 4 compound in this paper belongs to a group of double barium lanthanide molybdates BaLn 2 (MoO 4 ) 4 (Ln = Y, La–Lu) [9,10] . The structure of this scheelite-like compound, which is different from the scheelite one, contains a MoO 4 tetrahedron, a distorted GdO 8 polyhedron and Ba 2+ ions in the tenfold coordination [11] . It belongs to the monoclinic crystal category and has the space group C2/c with the cell parameters a = 5.2694 Å, b = 12.6659 Å, c = 19.4108 Å and β = 91.399 [12] . In our previous study, the Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 phosphor has been synthesized by high-temperature solid state method [13] . It is known that the co-doping behavior of rare earth activator ions can increase the efficiency of luminescence. So Yb 3+ is chosen as the co-dopant with Er 3+ , because it possesses a large absorption cross section at 980 nm, and the upconversion luminescence of Yb 3+ /Er 3+ doped molybdate and tungstate crystals have been reported [14,15] . Among them, metastable level 4 I 9/2 and 4 I 11/2 of Er 3+ ions can be populated upon 980 nm excitation [16,17] . However, a distinct enhancement of the intensity of upconversion luminescence was observed when Yb 3+ ion was doped as sensitizer [18,19] . Because Yb 3+ ion possesses a larger absorption cross section at 980 nm than Er 3+ , more Er 3+ ions can be populated to the excited-state by energy transfer from Yb 3+ ions, causing the enhancement of the emission of upconversion luminescence [20,21] . It is well-known that the solid state method used to prepare phosphor powders will result in the increase of particle sizes, which leads to poor adhesion to the substrate and loss of coating in practical application. However, Sol–gel method is one of the most important “soft chemistry” techniques for the synthesis of phosphor materials with higher uniformity in particle size distribution and non-agglomeration, and ultrafine powders [22] . In this paper, we reported the preparation of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ phosphors by sol–gel method process and their luminescence properties, and the possible upconversion luminescence mechanisms were also discussed. 2 Experimental Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 powder samples were prepared by the sol–gel method. The starting materials were Ba(NO 3 ) 2 (A.R.), (NH 4 ) 6 Mo 7 O 24 ·4H 2 O (A.R.), Gd 2 O 3 (99.99%), Yb 2 O 3 (99.99%), Er 2 O 3 (99.99%), HNO 3 (A.R.), citric acid (A.R.) and distilled water. Rare earth oxides Gd 2 O 3 , Yb 2 O 3 , Er 2 O 3 were dissolved in HNO 3 , and corresponding rare earth nitrate solutions were formed. Then stoichiometric amount of Ba(NO 3 ) 2 and (NH 4 ) 6 Mo 7 O 24 ·4H 2 O were added under vigorous stirring. Citric acid was used as chelating agent for the metal ions. The molar ratio of citric acid to total chelate metal cations was x :1 ( x = 1–5). At the end, the pH value of the mixed solution was adjusted to 7–8 by the addition of suitable amount of dilute NH 3 ·H 2 O, and the highly transparent solution was obtained after stirring for a few minutes. With continuous heating at 403 K, the solution became viscous by evaporation and then turned into an ash-like solid precursor. Fine-sized UL phosphors were finally obtained after calcinations at different temperature (873–1173 K) for 4 h in air. As a comparison, BaGd 1.54 Yb 0.4 Er 0.06 (MoO 4 ) 4 was synthesized by the high-temperature solid state method at 1273 K, as reported in the Ref. [13] . Thermogravimetry–differential thermal analysis (TG–DTA) for the precursor was performed on a SHIMADZU DTA-60H instrument. The analyzer was operated at a heat rate of 10 °C/min from room temperature to a maximum temperature of 1173 K. The X-ray diffraction (XRD) patterns were recorded by using a SHIMADZU model XRD-6000 X-ray powder diffractometer (Cu Kα radiation, 40 kV, 30 mA and a scanning speed 2.0° (2 θ )/min.). The size and shape of the particles were analyzed by a scanning electron microscope (SEM, JOEL, JSM-6490). The upconversion luminescence spectra were recorded on a Hitachi F-4500 spectrophotometer equipped with an external power-controllable 980 nm semiconductor laser (Beijing Viasho Technology Company, China) as the excitation source, which is connected with an optic fiber accessory. 3 Results and discussion Fig. 1 gives the TG–DTA curves of precursors of BaGd 1.54 Yb 0.4 Er 0.06 (MoO 4 ) 4 with different amount of citric acid. As seen in Fig. 1 (a), there are three weak endothermic peaks before the temperature gets to 450 K, which is due to the evaporation of small amount of absorbed or bonding water in different bonding state for the present complex precursor system. The weight loss of the precursor occurs in the TG curve from 450 to 546 K, which also corresponds to a strong exothermic peak at 478 K in DTA curve. This stage should originate from the decomposition and burning of organic chelate agents. After that, there is an endothermic peak from 540 to 850 K in DTA curve, but no obvious weight loss can be found in TG curve, which indicates the final formation of the single phase BaGd 1.54 Yb 0.4 Er 0.06 (MoO 4 ) 4 materials. In Fig. 1 (b), the position of the exothermic and endothermic peaks are nearly the same as Fig. 1 (a), which indicates that the amount of citric acid was not related to the temperature of the formation of the phosphors. Fig. 2 exhibits the XRD pattern of the BaGd 1.54 Yb 0.4 Er 0.06 (MoO 4 ) 4 samples obtained by sintering the precursor at different temperature and the JCPDS Card No.36-0192. As shown in the graph, 873 K is high enough to form the phase of the upconversion luminescence phosphor, and the XRD pattern of the samples have no obvious differences when the reaction temperature is changed from 873 to 1173 K, which also indicates that the upconversion luminescence powder can be achieved after sintering the precursor at 873 K. By comparisons among the given XRD pattern, we confirm that the crystal structure of the as-synthesized Yb 3+ /Er 3+ codoped BaGd 2 (MoO 4 ) 4 phosphor are in good agreement with the standard value from the JCPDS file of BaGd 2 (MoO 4 ) 4 except some extra peaks of data of Mo 4 O 11 and Mo 9 O 26 . It means that the BaGd 1.54 Yb 0.4 Er 0.06 (MoO 4 ) 4 phosphor can be obtained successfully by the sol–gel method. Fig. 3 displays the XRD pattern of the BaGd 1.54 Yb 0.4 Er 0.06 (MoO 4 ) 4 powders with different concentrations of citric acid when the reaction temperature was 1073 K. it can be concluded from the picture that the reactions for all the samples were complete. To further understand the crystal growth process of the BaGd 1.54 Yb 0.4 Er 0.06 (MoO 4 ) 4 phosphors, we investigated the morphology of the as-prepared products which are obtained at different reaction temperatures. Fig. 4 shows SEM images of the samples which are achieved by sintering precursors at different temperature (873 K, 973 K, 1073 K and 1173 K) for 4 h, respectively. As seen from Fig. 4 , there is an obvious grain growth trend with increasing temperature. The sample sintered at 873 K has the smallest grain size, which is less than 1 μm. The grain size of the powder is growing up while the temperature is increasing, and the lager grain (3– μm) can be found when the reaction temperature reach 1173 K. Particle aggregation took place with the increasing temperature, and the phosphor became blocky microcrystals when the sample was obtained by annealing the precursor at 1173 K. The upconversion luminescence properties of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ with different amount of citric acid after sintering the precursor from 873 to 1173 K are comparatively investigated in detail under 980 nm semiconductor laser excitation. As shown in Fig. 5 , two peaks at 530 nm and 550 nm of intense green emissions attributed to the transition emission of Er 3+ ( 2 H 11/2 → 4 I 15/2 and 4 S 3/2 → 4 I 15/2 ) are observed. Fig. 5 (a) gives the upconversion luminescence spectra of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ phosphor for calcination at 873 K, and the molar ratio of citric acid to total chelate metal cations was x :1 ( x = 1–5). It can be seen from the graph that the emission intensity maximizes when the ratio was 2:1. Similarly, as given in Fig. 4 (b–d), when the ratio was 2:1, the emission intensity reaches a maximum by sintering the samples at 973 K, 1073 K and 1173 K, respectively. In our work, we confirm that the optimum molar ration of citric acid to the metal cations for complete reaction should be 2:1, because the emission intensity of the samples with this concentration of chelating agent is stronger than any others. Fig. 6 shows the upconversion luminescence spectra of BaGd 2 (MoO 4 ) 4 :Yb 3+ , Er 3+ phosphor under 980 nm semiconductor laser excitation for different reaction temperature, and the molar ratio of citric acid to total chelate metal cations was 2:1. As seen from the graph, the upconversion luminescence emission intensity increases with the increasing reaction temperature, maximizes at 1073 K, and then decreases at 1173 K. Eventually, we confirm that optimum temperature for sintering the precursor is at 1073 K. In our former study, the phosphor with intensive green emission of upconversion luminescence has been synthesized by the solid state reaction [13] . In order to prepare ultrafine powder with stronger luminescence intensity, the same BaGd 2 (MoO 4 ) 4 :Yb 3+ , Er 3+ phosphor was obtained by sol–gel synthesis. Fig. 7 displays the upconversion luminescence intensities of the phosphors obtained by sol–gel method and the high-temperature solid state method, respectively. The concentrations of Yb 3+ and Er 3+ of the sample synthesized by sol–gel method is the same as the earlier sintered powder in our previous work [13] , which are 40 mol% and 6 mol%, respectively. As seen from Fig. 7 , the powder prepared by solid state method has a little stronger luminescence intensity. But as mentioned above, we can obtain the phosphor powders with higher uniformity in particle size distribution by sol–gel synthesis compared to the solid state method, which helps to obtain the practical application of the phosphor powders. The upconversion visible emissions of BaGd 2 (MoO 4 ) 4 :Yb 3+ ,Er 3+ are produced through multiple process including ground-state absorption (GSA), excited-state absorption (ESA) and energy transfer (ET) when excited with 980 nm semiconductor laser. The possible upconversion luminescence mechanism is shown in Fig. 8 . An Yb 3+ ion is excited by a 980 nm photon from ground state ( 2 F 7/2 ) to ( 2 F 5/2 ) through GSA process, and then promotes an Er 3+ ion from 4 I 15/2 to 4 I 11/2 by transferring the energy to it. Then the excited Er 3+ ion transits to a higher level at 4 F 7/2 when another Yb 3+ ion at 2 F 5/2 level continuously transfers the energy to it. Besides, the Er 3+ ion can be excited to 4 I 11/2 by a GSA process. And then the Er 3+ ion at excited state can also be promoted to the 4 F 7/2 level by absorbing a 980 nm photon through an ESA process. The populated level 4 F 7/2 decays non-radiatively to 2 H 11/2 and 4 S 3/2 , finally produces green emissions at 530 nm and 550 nm with a radiative transition to ground state 4 I 15/2 , respectively. It can be concluded that the occurrence of green upconversion can be attributed to a two-photon process. Moreover, cross relaxation occurs between the Er 3+ ions at level 4 I 11/2 and 4 I 13/2. The excited Er 3+ at level 4 I 11/2 relaxes to 4 I 13/2 with non-radiative transition. Then the Er 3+ of level 4 I 13/2 return to ground state 2 F 7/2 , transferring the energy to that of level 4 I 11/2, which promotes it to 4 F 7/2 level. The dependence of upconversion luminescence intensity upon the excitation power of laser diode is shown in Fig. 9 to further understand the involved mechanism. The relationship between the intensity of the upconversion luminescence and the infrared excitation can be approximately expressed as follow: I uc ∝ P n , where n is the number of infrared photons absorbed for emitting a visible photon. In the double-log coordinate graph shown in Fig. 9 , the slope of I uc − P n indicates the value of n , which is used for the deduction of the possible upconversion luminescence process. The value of n for emissions at 530 nm and 550 nm are 1.72 and 1.74, respectively. The decrease of n due to the competition between linear decay and upconversion processes for the depletion of the intermediate excited states has been reported [23] . The upconversion luminescence intensity for an n -photon energy transfer process was proportional to the n -th power of the excitation power ( P n ) in the limit of the infinitely small upconversion rates, while the intensity was proportional to the excitation power ( P 1 ) in the limit of infinitely large upconversion rates. Therefore, the intensity of an upconversion luminescence excited by the sequential absorption of n photons has a dependence of P β on absorbed excitation power P with 1 < β < n [23] , which give rise to the phenomenon that the slope coefficient is less than 2 in fig. 9 . As the result, it can be concluded that the green emission of BaGd 2 (MoO 4 ) 4 :Yb 3+ , Er 3+ phosphor is originated from a two-photon process. Further, the quenching effect of Er 3+ ion is also investigated. Fig. 10 shows the upconversion luminescence spectra of BaGd 2 (MoO 4 ) 4 :Yb 3+ , Er 3+ excited by a 980 nm semiconductor laser for different Er 3+ concentration and invariable Yb 3+ concentration (40 mol%). With increasing Er 3+ concentration, the green emission intensity increases, maximizes at 6 mol%, and then decreases. It can be seen from the inset of the Fig. 10 that the quenching effect for the green emission of BaGd 2 (MoO 4 ) 4 :Yb 3+ , Er 3+ is obvious when the concentration of Er 3+ is increasing. The concentration quenching is explained by the energy transfer between nearest Er 3+ ions. That is, the probability for a non-radiative energy transfer between Er 3+ ions increases with increasing the Er 3+ concentration. Such a non-radiative energy transfer occurs as a consequence of an exchange interaction or multipole–multipole interaction. In the case of the Er 3+ ion, the exchange interaction is responsible for energy transfer for forbidden transitions [24] . Then, the critical distance corresponding to the critical quenching concentration can be estimated by the following equation [25] . (1) R c ≈ 2 3 V 4 π x c N 1 3 where V is the unit cell volume, N is the number of Gd 3+ (Yb 3+ , Er 3+ ) ions in the present BaGd 2 (MoO 4 ) 4 :Yb 3+ , Er 3+ unit cell, and x c is critical concentration. According to crystal structure data of the BaGd 2 (MoO 4 ) 4 compound, it has a monoclinic phase, its cell volume ( V ) is 1295.06 Å, and the N value is 4. Considering the critical concentration is 0.06, the critical distance is about 21.5 Å. 4 Conclusion In conclusion, green upconversion luminescence phosphor BaGd 2 (MoO 4 ) 4 :Yb 3+ , Er 3+ has been synthesized by the sol–gel method. The morphologies of the phosphor are analyzed by SEM, and the grain growth trend with increasing temperature is observed. The luminescent properties and the effects of the sintering temperature and the amount of the chelating agent (citric acid) have been investigated in detail. The intensity of the green upconversion luminescence emission arrives at maximum when the molar ratio of citric acid to total chelate metal cations is 2:1 and the temperature of synthesis is at 1073 K. It is concluded that the green emissions at 530 nm and 550 nm which are due to the transition of Er 3+ ( 2 H 11/2 ) → Er 3+ ( 4 I 15/2 ) and Er 3+ ( 4 S 3/2 ) → Er 3+ ( 4 I 15/2 ) are produced through a two-photon process. The quenching effect of the Er 3+ concentration has also been studied. The optimum Er 3+ doping concentration should be 6 mol%, and the critical distance for the neighboring Er 3+ was determined to be about 21.5 Å.

The reflection differences between the host materials and the coatings were increased by optimizing the number of layers and the arrangement order. The optically variable effect was investigated by X-Rite MA86 II five angles spectrophotometer. The impact of symmetrical configurations on improving the color travel effect was studied, and the influence of different coating materials on the hue and the color travel effect was researched. The results show that the reflection rate and the color travel effect of the pigment were improved by coating another material on three symmetrical configurations.",

The crystallization process, structure, and morphology of the as-synthesized phosphor were characterized by thermogravimetry-differential thermal analysis, X-ray diffraction, and scanning electron microscopy analysis, respectively. The luminescence properties were characterized by diffuse reflection spectra (UV-visible) and photoluminescence spectra. The as-prepared phosphors had good excitation characteristics in the region of 320-450 nm, which perfectly matched the emission wavelength of near-UV light emitting diodes. Intense red emission peaking at 608 nm was obtained upon 365 nm excitation with the chromaticity coordinates of (0.585, 0.402). The energy transfer among the nearest-neighbor ions resulted in the concentration quenching of Ba2 Mg (BO3) 2: Eu2+phosphor, and the critical distance was determined to be about 17.32 Å. © 2009 The Electrochemical Society.",

The final products were characterized by various measurement techniques. Many preparation conditions, e.g., the content of added precursors, reaction time and pH value, were optimized to obtain nanocomposites including relatively uniform nanoparticles with strong upconversion (UC) emission intensity. The measurement results showed that the anatase TiO2 nanobelts, supported by the large number of β-NaYF4:Yb3+,Er3+ nanoparticles with 30-70 diameter range and very strong UC emission, could be achieved under suitable preparation condition. The UC emission intensity of the nanoparticles with the concentrations of Yb3+ and Er3+ closer to 20 mol. and 1 mol. was the strongest. © 2010 The Chinese Society of Rare Earths.",

B-site substituted Sr2Ca0.8Eu0.1Na0.1MoO6 phosphor, in which Na+ ions act as charge compensators, was selected to study the thermal behavior, phase structure, microstructure, and photoluminescence property under different sintering temperatures. The photoluminescence studies on Sr2Ca1−2x Eu x Na x MoO6 (x = 0.02, 0.05, 0.10, 0.15, 0.2) show that a dominant red emission line at around 594 nm, which is due to the Eu3+ magnetic dipole transition of 5D0–7F1, is observed under different Eu3+ excitations (396 and 412 nm). Further, Eu3+ dopant content dependent emission spectra investigations of Sr2Ca1−2x Eu x Na x MoO6 phosphors indicates that, when the Eu3+ concentrations x = 0.05, there are minimum differences between the emission intensity of 5D0–7F1 transition at 594 nm and that of 5D0–7F2 transition at 615 nm. With increasing Eu3+ concentration, the variation of the emission intensities between the two transitions keep nearly invariable and Sr2Ca0.8Eu0.1Na0.1MoO6 phosphor has the strongest red emission in this series.",

Their structures and photoluminescence properties were comparatively investigated. It was found that the mixture phases of Sr2MgSi2O7 and SrF2 were obtained when a part of Sr2+ in Sr2LiSiO4F was replaced by some amount of Mg2+ in order to design the possible SrMgLiSiO4F:Eu2+ phosphor. Based on the photoluminescence analysis, Sr2LiSiO4F:Eu2+ phosphor exhibited a green broad emission band of main peak at 513 nm under the excitation of 365 nm, while the Sr2MgSi2O7:Eu2+ and SrMgLiSiO4F:Eu2+ phosphor showed blue emission centered at 467 nm. The temperature dependent photoluminescence properties and room temperature decay time for the three kinds of phosphors were also discussed in this paper.",

The final products were characterized by various measurement techniques. Many preparation conditions, e.g., the content of added precursors, reaction time and pH value, were optimized to obtain nanocomposites including relatively uniform nanoparticles with strong upconversion (UC) emission intensity. The measurement results showed that the anatase TiO2 nanobelts, supported by the large number of β-NaYF4:Yb3+,Er3+ nanoparticles with 30–70 diameter range and very strong UC emission, could be achieved under suitable preparation condition. The UC emission intensity of the nanoparticles with the concentrations of Yb3+ and Er3+ closer to 20 mol.% and 1 mol.% was the strongest.",

"title": "Upconversion Luminescence Properties of NaYF_4∶Tm~(3+),Yb~(3+) Synthesized by Co-precipitation Method",
"abstract": "The upconversion(UC) processes of infrared light to visible light of rare earth ions doped different hosts have been investigated extensively,due to their potential applications in some fields,such as solid-state lasers,display,communications,and so on.The recent researches emerging at the intersection of nanotech-nology and biotechnology are opening up a new period for the development of UC.As known,the controlled fabrication of a host with aimed structure is important for enhancing the upconversion efficiency,because the phonon energy of the host can affect the probabilities of non-radiative decay and the energy transfer.Therefore,it is necessary to choose a lattice with much lower phonon energy,which is benefit to the upconversion luminescence.Rare earth-doped hexagonal sodium yttrium fluoride(NaYF4) is a good host,which is known to be a very efficient near-infrared to visible upconverter.The hexagonal NaYF4 has low phonon energy.The structure of hexagonal phase gives rise to controversy about the cation sites and distribution.The trivalent thulium(Tm~(3+)) is an ideal candidate for single wavelength NIR upconversion due to its ladder of nearly equally spaced energy levels that are multiples of the 1G4→3H6 transition.The development of compact blue lasers based on Tm~(3+) upconversion processes is nowadays widely studied mainly due to the potential of high perfor-mance OEM applications,such as biomedical and analytical instrumentation,display,photoprinting.In thu-lium doped media,the efficiency of this process is very low,but it was noticed that the mechanism could be made one or two orders of magnitude more efficient by using ytterbium(Yb~(3+)).In this paper,trivalent thu-lium(Tm~(3+)) and yttebium(Yb~(3+)) ions codoped NaYF4 were synthesized by co-precipitation method.The concentration of Tm~(3+) and Yb~(3+) are 0.01%,0.1%,respectively.The absorption spectrum of NaYF4∶Tm~(3+),Yb~(3+) from 300 to 1 100 nm was measured at room temperature.The upconversion emission was observed when excited by 798 nm.The green and blue upconversion emission spectra were measured.Based on the experimental results the possible upconversion mechanism was analyzed.The main mechanism is the in-direct sensitization of Tm~(3+) and Yb~(3+).The blue emitting light results from the transition of 1G4→3H6 of Tm~(3+),green emitting light is from the transition of 1D2 →3F4 of Tm~(3+).To our knowledge,there have not been similar works published domestically and abroad.The structural properties of the samples were characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM).The results show that NaYF4∶Tm~(3+),Yb~(3+) prepared by co-precipitation method exhibits hexagonal crystal phase.",

The Sr 3Gd(PO 4) 3:Ce 3+,Eu 2+ phosphor showed two emission bands under 310 nm excitation: the one observed at 374 nm was assigned to the 4f 05d 1 → 4f 1 transition of Ce 3+ ion emission, and the other found at 518 nm was attributed to the 4f 65d 1 → 4f 7 transition of Eu 2+ ions. The energy transfer from Ce 3+ to Eu 2+ in Sr 3Gd(PO 4) 3 host matrix was studied and demonstrated to be a resonant type via a dipole-quadrupole mechanism. Furthermore, we have calculated the critical distance for Ce 3+ → Eu 2+ energy transfer to be about 32.02 by the concentration- quenching method. Preliminary results indicate that the phosphor might be a promising green phosphor for UV-based white LEDs. © 2012 Elsevier B.V. All rights reserved.",

X-ray diffraction (XRD), diffuse reflection (UV-vis) and photoluminescence spectra were utilized to characterize the crystallization process, structure and luminescence properties of the as-synthesized phosphors. The XRD results indicated that the sample began to crystallize at 800 oC, and single-phase BaCaBO3F was fully obtained after annealing at 1000 oC. The charge compensated behaviors were investigated in this paper by considering different cations like Li+, Na+ and K+ acting as the charge compensator. The as-prepared phosphors had better emission properties, and the two characteristic emission lines peaking at 590 and 615 nm could be obtained upon 394, 463 and 532 nm excitation with the chromaticity coordinates of (0.596, 0.391), which were due to 5D0–7F1 and 5D0–7F2 transitions of Eu3+ ions.

"abstract": "Micro- and nanocrystals cubic-phase SrF2:Yb3+/Er 3+ upconversion luminescence phosphors were synthesized via a facile hydrothermal route in the presence of different surfactants. The samples were characterized with X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and upconversion emission spectra. As-prepared products showed a variety of morphologies, such as cubic-shaped microcrystal, hierarchical structure microspheres, spherical-shaped nanocrystals and nanosheets. The intrinsic structural feature of cubic-phase SrF2 and two important external factors, namely, the surfactants in the reaction solution and fluoride sources, were responsible for shape determination of SrF2:Yb 3+/Er3+. The possible formation mechanisms for products with various architectures were presented. A systematic study on the photoluminescence of Yb3+/Er3+-doped SrF2 samples with cubic shape, microspheres, spherical and nanosheets shapes showed that the optical properties of these products were strongly dependent on their morphologies and size. © 2011 The Chinese Society of Rare Earths.",

X-ray powder diffraction (XRD) analysis confirmed the phase formation of SrB4O 7:Sm2+ materials. Results of luminescence properties showed that the phosphor could be efficiently excited by the UV-vis light region from 250–500 nm, and it exhibited deep red (685 nm) emission corresponding to 5D0 → 7F0 transition of Sm 2+ . The critical quenching concentration of Sm 2+ in SrB4O7 :Sm 2+ phosphor was about 0.05, and the corresponding concentration quenching mechanism was verified to be the dipole-dipole interaction according to the Dexter’s theory. The decay times had few alterations with different concentrations in SrB4O7:xSm 2+ phosphor.",

"abstract": "Ce3+ and Tb3+ co-doped Sr3Gd(PO 4)3 phosphors were synthesized by the solid-state method. The phase structure and luminescence properties of the phosphor samples were characterized by using powder X-ray diffraction (XRD), photoluminescence (PL) excitation and emission spectra, decay time, respectively. The obtained phosphor exhibits a strong excitation band between 200 and 400 nm, matching well with the dominant emission band of a ultraviolet (UV) light-emitting-diode (LED) chip. Effective energy transfer occurred from Ce3+ to Tb3+ in Sr3Gd(PO4)3 hosts due to the spectra overlap between the PL emission spectrum of Ce3+ ion and the PL excitation spectrum of Tb3+ ion. The energy transfer from Ce 3+ and Tb3+ in Sr3Gd(PO4) 3 host was demonstrated to be resonant type via a dipole-dipole interaction mechanism with the energy transfer critical distance of 1.87 nm. Furthermore, Sr3Gd(PO4)3:Ce3+, xTb3 can be systematically tuned to generate blue light to yellow-greenish light under UV excitation. It can serve as a potential color-tunable UV phosphor for white-light LED (w-LEDS) devices. © 2013 Elsevier Ltd.",

"abstract": "A blue-emitting Ca 2 B 5 O 9 Br:Eu 2+ phosphor for white light-emitting diodes was synthesized via a microwave calcination route. The phosphor powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and fluorescence spectrophotometer, respectively. The obtained results revealed that the Ca 2 B 5 O 9 Br:Eu 2+ phosphor prepared by the microwave calcination route possessed a rod-like morphology with the single phase orthorhombic structure. Based on the photoluminescence analysis, it was found that Ca 2 B 5 O 9 Br:Eu 2+ phosphor exhibited a broad excitation band chiefly in the near ultraviolet region (270–420 nm) and a blue broad emission band of main peak at 452 nm under the strongest excitation of 411 nm. Further investigation on concentration-dependent emission spectra indicated that Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor exhibited the strongest luminescent intensity, and the concentration quenching for the two Eu-site emission centers was caused by dipole–dipole interactions. Keywords Optical materials Optical properties 1 Introduction Nowadays, increasing interests have been focused on GaN/InGaN-based white light-emitting diodes (LEDs) [1,2] . Among them, there are several ways to obtain the phosphor-converted white LEDs. One scheme is the combination of the blue LEDs chip and the yellow-emitting phosphor, and the other is the combination of the near ultraviolet (n-UV) LEDs chip and the red, green and blue emission phosphor [3,4] . In order to fulfill the corresponding requirements, many research papers on developing new phosphor systems used as light-conversion phosphors for white LEDs have been reported [5–10] . Among them, the studies on halo-based materials, such as halophosphate phosphors [7] , haloborate phosphors [8] , halosilicate phosphor [9] and haloaluminate phosphors [10] , become a hot issue in exploring new phosphor materials, and they have also been proved to be efficient in the application of the white LEDs light-conversion phosphors. During the process of the exploration in haloborate-based light-conversion phosphors for white LEDs, Yang [8] recently reported the yellow-emitting phosphor Ca 2 BO 3 Cl:Eu 2+ , and Zhang [11] investigated the red-emitting phosphor Sr 5 (BO 3 ) 3 Cl:Eu 2+ . In this paper, we firstly developed a novel blue-emitting phosphor Ca 2 B 5 O 9 Br:Eu 2+ for white LEDs. Undoubtedly, a technological problem in working with halo-based materials is the need to control the loss of weight of halide starting materials at high-temperature, which induced the deviation of the proposed composition of the phosphors [12] . Compared to the conventional high-temperature solid-state method, microwave synthesis has the advantages of shortening reaction time, small particle size, narrow particle size distribution and high purity. Consequently, for the first time, we adopted the direct microwave calcination route to prepare halo-based phosphor materials Ca 2 B 5 O 9 Br:Eu 2+ . The homogeneous products can be obtained in the relative low reaction temperature and short processing time. Accordingly, the structure, morphology and photoluminescence properties of Ca 2 B 5 O 9 Br:Eu 2+ phosphors via direct microwave calcination route were studied thoroughly in this paper. 2 Experimental The powder samples of Ca 2 B 5 O 9 Br: x Eu 2+ ( x = 0.005, 0.01, 0.03, 0.05, 0.1 and 0.2) were prepared using direct microwave calcination route. The starting materials used in the preparation were CaCO 3 (A.R.), CaBr 2 ·2H 2 O (A.R), H 3 BO 3 (A.R.) and Eu 2 O 3 (99.999%). With a mole ratio of CaCO 3 , CaBr 2 ·2H 2 O, H 3 BO 3 (A.R.) and Eu 2 O 3 = (1.5 − x ):0.55:5: x /2, the raw materials were thoroughly mixed by grinding in an agate mortar, and then placed in corundum crucible. A little excessive CaBr 2 (10%) is necessary for loss of weight in the process of the microwave calcination reaction, and it also can be acted as the flux. The highly pure carbon grains were used as a reducing agent in the microwave calcination process. The microwave calcination technique was dealt with in the Phoenix microwave ashing systems (CEM Microwave Technology Ltd., USA, frequency: f = 2450 MHz, power: P max = 1400 ± 50 W and temperature: T max = 1200 °C). The power of the microwave oven can be adjusted; accordingly its temperature and heating rate is under control. Based on this, the selected optimum microwave calcination condition was as follows; the mixed starting materials were heated by microwave energy from room temperature to 500 °C in 45 min, and processed at 500 °C for another 30 min to obtain the final Ca 2 B 5 O 9 Br:Eu 2+ phosphor materials. The X-ray diffraction patterns were recorded by using a SHIMADZU model XRD-6000 X-ray powder diffractometer (Cu kα radiation, 40 kV, 30 mA and a scanning speed 2.0°(2 θ ) min −1 ). The scanning electron microscope (SEM) (Model CSM950, OPTON, Germany) was employed to analyze the morphology of the typical sample. The excitation and emission spectra were recorded by using a PerkinElmer LS-55 fluorescence spectrophotometer with a photomultiplier tube operating at 400 V, and a 150 W Xe lamp was used as the excitation lamp. The temperature-dependence luminescence properties were measured on a HITACHI F-4500 spectrophotometer, which was combined with a self-made heating attachment and a computer-controlled electric furnace. 3 Results and discussions In 1973, Lloyd et al. [13] reported the crystal structure of Ca 2 B 5 O 9 Br for the first time, and they found that Ca 2 B 5 O 9 Br had an orthorhombic structure with a space group of Pnn 2 and lattice constants of a = 11.397(2) Å, b = 11.397(2) Å, c = 6.293(1) Å, and υ (cell volume) = 817.41 Å 3 . However, after that, there are only some reported works on Ca 2 B 5 O 9 Br series haloborates phosphor as a promising storage phosphor for X-ray imaging [14] . In this paper, we have prepared Ca 2 B 5 O 9 Br:Eu 2+ phosphor for white LEDs via the microwave calcination route. Fig. 1 gives the XRD patterns of 0.03Eu 2+ -doped Ca 2 B 5 O 9 Br phosphor, as-synthesized Ca 2 B 5 O 9 Br host and JCPDS Card file (No. 73-1013) of Ca 2 B 5 O 9 Br. By careful comparison among the given XRD patterns, their positions and intensities of the main peaks are nearly the same. It indicates that the crystal structure of the as-synthesized Ca 2 B 5 O 9 Br:Eu 2+ phosphor and Ca 2 B 5 O 9 Br host are in good agreement with the standard value from the JCPDS files of Ca 2 B 5 O 9 Br as reported by Lloyd. The present result means that the pure crystal structure of Ca 2 B 5 O 9 Br can be obtained successfully by the microwave calcination method. And the synthesis temperature is at least 300 °C lower than the conventional high-temperature solid-state method. Further, it also indicates that the crystal structure of Ca 2 B 5 O 9 Br has no obvious change after Eu 2+ doping. Fig. 2 shows the SEM image of as-synthesized Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor by microwave calcinations technique. SEM result shows that rod-like Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor grains with an average diameter of about 4–5 μm long and about 1 μm wide are uniformly distributed. Further, no sintering behavior found in the microwave heating may be attributed to a quite shorter heating and processing time. Especially, the special rod-like particle morphology under microwave irradiation can be ascribed to the so-called “thermal-runaway” phenomenon [15,16] . The existed “hot spots” were induced on the high curvature surface of mixed starting materials resulting from tending focusing of electromagnetic field. Rapid absorption of hot spots evolved in a thermal-runaway process could lead to surface melting, which in turn leads to the formation of many rod-like Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor grains. Fig. 3 presents the excitation [photoluminescence excitation (PLE); λ em = 452 nm] and emission (PL; λ ex = 411 nm and 343 nm) spectra of Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor. The PLE spectra have a broad band between 270 and 420 nm, and there are three excitation peaks around 276, 342 and 411 nm, which corresponds to the 4f–5d transition of Eu 2+ ions [17] . The above fine structure of the excitation spectra of Eu 2+ ions indicate that the site occupied by the Eu 2+ ions have a lower symmetry. The phosphor emits blue luminescence with a peak wavelength of 452 nm, and the full width at half maximum (FWHM) of this sample is about 32 nm, which shows a purer color than commercial BaMgAl 10 O 17 :Eu 2+ blue phosphor (FWHM = 51 nm) [18] . The calculated Stokes shift is about 2210 cm −1 . As is also shown in Fig. 3 , it gives the emission spectra of Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor under different excitation wavelength, 411 and 343 nm. It indicates that both emission spectra have no significant changes in the spectra configuration except for the emission intensity. The water resistance and heat-resistance of the selected Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor is also investigated. It is found that the phase structure and luminescence properties of Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor keep nearly invariable after it is soaked in the water for 24 h, which indicates that Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor has stable crystal structure and well water resistance. Fig. 4 shows the emission spectra of Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor at various temperatures. It can be seen that the Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor has comparatively low-temperature quenching effect and good heat-resistance. With increasing temperature up to 200 °C, the normalized emission intensity is decreased to 65.6% of the initial value. All the results may be due to the good thermal stability and chemical stability of Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor, which will be crucial for its potential application in white LEDs. Further, Fig. 5 gives the emission spectra of Ca 2 B 5 O 9 Br:Eu 2+ phosphor for various Eu 2+ concentrations upon 411 nm near UV excitation. As a summarization, Table 1 gives the measured and calculated optical properties parameters of Ca 2 B 5 O 9 Br: x Eu 2+ phosphor. As is shown by the data in Table 1 , the peak positions were obviously red shifted as the Eu 2+ content increased for the low Eu 2+ concentrations Ca 2 B 5 O 9 Br: x Eu 2+ phosphor. While in the high Eu 2+ concentrations Ca 2 B 5 O 9 Br: x Eu 2+ phosphor compositions, the peak positions kept nearly invariable. The similar variation trend was also found in the other two optical properties parameters, FWHM and Stokes shifts. But the variation of emission intensities appears just like a part of a parabola. The emission intensity increases from x = 0.005 to x = 0.03, and the strongest emission were obtained at the compositions of x = 0.03 (Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor), then it displays a decrease trend with further increase of x values. The inset of Fig. 5 shows the concentration dependence of the emission intensities of Ca 2 B 5 O 9 Br: x Eu 2+ phosphor. As mentioned above, Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor has the strongest blue emission. It is well known that the fluorescence mechanism of Eu 2+ in Ca 2 B 5 O 9 Br system is the 4f–5d allowed electric-dipole transition, the process of energy transfer should be controlled by electric multipole–multipole interaction. According to the report of Van Uitert [19] , if the energy transfer occurs among the same sorts of activators, the intensity of multipolar interaction can be determined from the change of the emission intensity from the emitting level which has the multipolar interaction. The emission intensity ( I ) per activator ion follows Eq. (1) : (1) I x = K [ 1 + β ( x ) θ / 3 ] − 1 where I / x is the emission intensity ( I ) per activator concentration( x ), K and β are constants for each interaction for a given host crystal, and θ is an indication of electric multipolar character; θ = 6, 8 and 10 for dipole–dipole (d–d), dipole–quadrupole (d–q), and quadrupole–quadrupole (q–q) interactions, respectively [19–20] . To get a correct θ value for the two emission centers, the dependence of log( I / x ) on log( x ) is plotted, and it yield a straight line with a slope equal to − θ /3. The fitting result for Eu 2+ emission centers, which is corresponding to the high Eu 2+ concentrations Ca 2 B 5 O 9 Br: x Eu 2+ phosphor compositions, is shown in Fig. 6 . The value of θ can be calculated as 6.63, which is approximately equal to 6. Since the value of θ equals to 6, it means that the quenching is dipole–dipole (d–d) interactions in the Ca 2 B 5 O 9 Br: x Eu 2+ phosphor compositions. 4 Conclusions In conclusion, novel blue-emitting Ca 2 B 5 O 9 Br:Eu 2+ phosphor powders were synthesized via the microwave calcination route. The pure Ca 2 B 5 O 9 Br phase structure was successfully obtained by microwave calcination route. The optimum process was as follows, the samples were heated from room temperature to 500 °C in 45 min, and processed at 500 °C for another 30 min. Scanning electron microscopy (SEM) image showed that the phosphor grains possessed a rod-like morphology phase. Investigation on concentration-dependent emission spectra indicated that Ca 2 B 5 O 9 Br:0.03Eu 2+ phosphor exhibited the strongest blue luminescence with a peak wavelength of 452 nm, FWHM of about 32 nm, Stokes shift of 2210 cm −1 , and the concentration quenching for the two Eu-site emission centers was caused by dipole–dipole interactions. The above obtained results indicated that this novel phosphor was promising as the blue component of light-conversion phosphors for white LEDs.

According to the Van Uitert experimental equation, luminescence properties and crystal-lattice environment of Eu2+ in Sr4-x. CaxSi3O8 Cl4 crystal were discussed. The possibilities of two Eu2+ emission centers, viz. blue and greenish-yellow centers, were found and their corresponding relationships with spectra were also discussed. When the doping amount of calcium(x) varied between 0 and 0.5, Ca2+ ions were embedded in the host lattice of Sr4Si3O8 Cl4, and the luminescence of blue center, which was ascribed to the emission of Eu2+ that substituted the octa-coordination Sr2+ sites, dominated and showed blue-green luminescence. Sr4-xCaxSi3O8 Cl4:yEu2+ exhibited greenish-yellow luminescence when the range of x was between 0.5 and 2. This was due to the fact that the Eu2+ emission originated from the formation of an impurity-trapped exciton state. Greenish-yellow emission center was located in the impurity-trapped exciton state which was the lowest excited state of this system, and the Eu2+ emission was at long wavelengths, and a large Stokes shift was observed.",

"abstract": "A near Infrared (NIR) quantum cutting (QC) Sr3AlO4F:Tb3+,Yb3+ phosphor was synthesized by the conventional high temperature solid-state reaction. The luminescence spectra both in visible (VIS) and NIR regions and decay lifetime curves of Tb3+ have been measured to prove energy transfer (ET) from Tb3+ to Yb3+. Quantum efficiency (QE) related to Yb3+ concentration was calculated and the highest QE was found to be 135% hen Yb3+ doped concentration at 20%. The present Tb3+ and Yb3+ co-doped Sr3AlO4F phosphor may be a promising candidate to modify the spectral of the solar light.",

"abstract": "Erbium and ytterbium co-doped sodium yttrium fluoride (NaYF4:Er3+,Yb3+) was synthesized by combusting in home microwave oven directly. The structure and morphology of the sample was characterized by the X-ray diffraction (XRD) and scanning electron microscopy (SEM), and its upconversion luminescence properties were investigated in detail. Under 980nm semiconductor laser excitation, the color of upconversion luminescence of NaYF4:Er3+,Yb3+ was green and red, and its upconversion spectrum exhibited distinct emission peaks at 522, 543 and 652 nm, the emission appears yellow-orange to the naked eye. The law of luminescence intensity versus pump power proved that the intense green emission at 522 and 543 nm were from Er3+ (H-2(11/2) -> I-4(15/2) and S-4(3/2) -> I-4(15/2)), and the weaker red emission at 652 nm was from Er3+ (F-4(9/2) -> I-4(15/2)), which belong to the two photon process.",

The luminescent properties of Ce 3+ and Tb 3+ co-doped Sr 2B 2O 5 phosphors were investigated by using the photoluminescence emission, excitation spectra and reflectance spectra, respectively. The excitation spectra indicate that this phosphor can be effectively excited by near ultraviolet (n-UV) light of 317 nm. Under the excitation of 317 nm, Sr 2B 2O 5:Ce 3+,Tb 3+ phosphors exhibited blue emission corresponding to the f-d transition of Ce 3+ ions and green emission bands corresponding to the f-f transition of Tb 3+ ions, respectively. The Reflectance spectra of the Sr 2B 2O 5:Ce 3+,Tb 3+ phosphors are noted that combine with Ce 3+ and Tb 3+ ion absorptions. Effective energy transfer occurred from Ce 3+ to Tb 3+ in Sr 2B 2O 5 host due to the observed spectra overlap between the emission spectrum of Ce 3+ ion and the excitation spectrum of Tb 3+ ion. The energy transfer efficiency from Ce 3+ ion to Tb 3+ ion was also calculated to be 90%. The phosphor Sr 2B 2O 5:Ce 3+,Tb 3+ could be considered as one of double emission phosphor for n-UV excited white light emitting diodes. © 2012 Elsevier Ltd and Techna Group S.r.l.

"abstract": "Multicolor emitting phosphors LiBaPO 4:RE (RE Eu 2+, Tb 3+, Sm 3+) reported as interesting down-conversion luminescent materials in white light-emitting diodes (w-LEDs) have been prepared by a conventional solid-state reaction. The excitation and emission spectra indicate that these phosphors can be effectively excited by the near-UV light, and emit blue, green, and red light, respectively. The photoluminescence properties, decay times, and Commission Internationale de I'Eclairage (CIE) chromaticity indexes are determined for various concentrations of the activators Eu 2+, Tb 3+, and Sm 3+ in LiBaPO 4 host. Furthermore, the temperature-dependent luminescence of these phosphors was investigated. The emission intensities of Tb 3+- and Sm 3+-doped LiBaPO 4 increased unexpectedly with increasing temperature. This interesting phenomenon is proposed to be the result of two ground states in the configurational coordination diagram. The present investigation suggests that LiBaPO 4:RE (RE Eu 2+, Tb 3+, Sm 3+) were potential candidates for application in w-LEDs. © 2012 American Institute of Physics.",

"abstract": "Microwave (MW)-induced shape-memory poly(vinyl alcohol)/poly(acrylic acid) (PVA/PAA) interpenetrating polymer networks (SMP-IPNs) were prepared through in situ polymerization. Silicon carbide (SiC) nanoparticles were modified by 3-(methacryloyloxy) propyltrimethoxysilane (KH570). 3-(Methacryloyloxy) propyltrimethoxysilane was covalently bonded on the surface of SiC through the reaction of silanol and the methoxy groups. The polymerization of acrylic acid (AA) using N,N′-methylenebis (2-propenamide) (MBA) as cross-linker in PVA solution was initiated through the double bonds of KH-570 grafted on SiC, leading to a PAA polymer network cross-linked with MBA. The PVA molecular chains run through the PAA cross-linking network and form an IPN structure. Therefore, SiC as a strong MW absorbing material could be chemically cross-linked into polymer matrix. The effect of composition on the properties of SMP-IPN was studied using dynamic mechanical analysis, dielectric properties and shape memory effect (SME) test. The results showed that the introduction of SiC in IPNs not only provided samples with excellent MW-induced shape memory effect (SME), but also caused a higher equilibrium temperature under MW irradiation. Moreover, both SiC content and applied MW power affected the shape recovery properties of PVA/PAA interpenetrating composites.

"abstract": "In this work, solid-state polymer supercapacitor (SSC) was assembled using poly(3,4-ethylenedioxythiophene/carbon paper (PEDOT/CP) as an electrode and ionic liquid (1-butyl-3-methylimidazole tetrafluoroborate)/polyvinyl alcohol/sulfuric acid (IL/PVA/HSO) as a gel polymer electrolyte (GPE). The GPE was treated through freezing-thawing (F/T) cycles to improve the electrochemical properties of PEDOT SSC. Cyclic voltammetry (CV), galvanostatic charge-discharge measurements (GCD) and electrochemical impedance spectroscopy (EIS) techniques and conductivity were carried out to study the electrochemical performance. The results showed that the SSC based on ionic liquid GPE (SSC-IL/PVA/HSO) has a higher specific capacitance (with the value of 86.81 F/g at 1 mA/cm) than the SSC-PVA/HSO.The number of F/T cycles has a great effect on the electrochemical performance of the device. The energy density of the SSC treated with 3 F/T cycles was significantly improved, reaching 176.90 Wh/kg. Compared with the traditional electrolytes, IL GPE has the advantages of high ionic conductivity, less volatility, non-flammability and wider potential window. Moreover, the IL GPE has excellent elastic recovery and self-healing performance, leading to its great potential applications in flexible or smart energy storage equipment.",

"abstract": "Recently, different stimuli triggered shape memory polymer composites (SMPC) have received much research interest. However, most shape memory effects (SME) in polymer composites are mainly caused by introducing different functional inorganic fillers into polymer matrix. In the present work, the special structure of poly(ionic liquids), the heating effect of microwaves (MW), and the mechanism of SMPs are combined to design MW induced SMPC completely based on polymers, poly(ionic liquid)/poly(vinyl alcohol) (PIL/PVA) polymer networks. PILs contain anion cation pairs, which have strong MW absorption capability due to their dielectric properties. Polymer composites absorb MW energy under irradiation and generate MW heating, which could provide the required energy for shape recovery. The functional ionic liquid monomer (MIL) styrene imidazole ([VBBI][BF4]) is synthesized and polymerized. Then, PIL is mixed into PVA solution, which is crosslinked with glutaraldehyde to form P[VBBI][BF4]/PVA polymer networks. 1H NMR is used to characterize the structure of the synthesized styrene imidazole ILM and PIL. A bending test is applied to quantitatively characterize SMEs, which are affected by the PIL content in the composites and the applied MW power output. The present work combines the advantages of microwaves with PILs, opening up an efficient and environmentally friendly field for SMPs.",

An ACPN film modified electrode exhibited excellent electrocatalytic activity, a low detection limit and a high sensitivity to ascorbic acid (AA). It is found that AA can be electro-catalytically oxidized on an ACPN film even at a concentration less than 1 mM. A mechanism of AA electrooxidation on the ACPN film modified electrode was proposed. Furthermore, the detection sensitivity was regulated by tuning the film thickness, and the optimized fabrication conditions for the ACPN film modified electrode was obtained. Based on the reaction kinetics study, the catalytic rate constant for the best electrode was found to be 6.3x10(6) cm(3).mol(-1).s(-1). It is expected that such a sensor based on the ACPN film can be widely applied for AA detection.",

In this paper, a kind of smart poly (vinyl alcohol) (PVA) hydrogel is obtained using 4, 4′-azodibenzoic acid as cross-link agent. The hydrogels have the ability of swelling and shrinking reversibly under irradiation by ultraviolet or visible light because azobenzene groups show trans–cis isomerization under suitable light wavenumber. Under UV irradiation, azobenzene takes the cis structure which leads to volume decreases; macroscopically, shrinking can be observed. Under visible light irradiation, the volume recovers, and swelling can be observed macroscopically. Hydrogels have excellent swelling/shrinking recovery properties even after 12 cycles. The procedure achieves loop control of the transformation from light energy to mechanical energy.",

"abstract": "Cancer represents a major threat to human health. Magnetic resonance imaging (MRI) provides superior performance to other imaging-based examination methods in the detection of tumors and offers distinct advantages in biopsy and seed implantation. However, because of the MRI environment, the material requirements for actuating devices for the medical robots used in MRI are incredibly demanding. This paper describes a novel double tendon-sheath transmission device for use in MRI applications. LeBus grooves are used in the original transmission wheels, thus enabling the system to realize long-distance and large-stroke transmission with improved accuracy. The friction model of the transmission system and the transmission characteristics model of the novel tendon-sheath structure are then established. To address the problem that tension sensors cannot be installed in large-stroke transmission systems, a three-point force measurement method is used to measure and set an appropriate preload in the novel tendon-sheath transmission system. Additionally, experiments are conducted to verify the accuracy of the theoretical model and multiple groups of tests are performed to explore the transmission characteristics. Finally, the novel tendon-sheath transmission system is compensated to improve its accuracy and the experimental results acquired after compensation show that the system satisfies the design requirements.",

Breast biopsy is a way to obtain tissue samples to determine if people suffer from breast cancer. Magnetic Resonance Imaging (MRI) can present the better performance in breast imaging than ultrasound or computed tomography, therefore a breast intervention robot for MRI guided biopsy of the breast was proposed in this paper. The structure of robot is nonmagnetic and thus the robot can operate safely within MRI scanner. Based on the study of the structure of the robot, the forward kinematics and inverse kinematics model of the robot was set up. According to the kinematics analysis and modeling, quintic polynomial interpolation methods were used in the trajectory planning of robot motion. Then the kinematics was also calculated by simulations. The simulation results showed that it can guarantee the continuous displacement, velocity and acceleration of joints. The smooth movement of the robot is vital to the physician, patient and robot itself, which helps to improve the safety of patient and the security of robot. Finally, the robot model was established and an experiment was carried out to prove that the robot runs smoothly and position accurately.",

"abstract": "Abstract For foundation soils surrounding the crude oil pipeline in permafrost regions, the soil properties and the upper boundary conditions are stochastic because of complex geological processes and changeable atmospheric environment. The conventional finite element analysis of thermal characteristics for crude oil pipeline is always deterministic, rather than taking stochastic parameters and conditions into account. This study investigated the stochastic influence of an underground crude oil pipeline on the thermal stability of the permafrost foundation on the basis of a stochastic analysis model and the stochastic finite element method. A stochastic finite element program is compiled by Matrix Laboratory (MATLAB) software, and the random temperature fields of foundation soils surrounding a crude oil pipeline in a permafrost region are obtained and analyzed by Neumann stochastic finite element method (NSFEM). The results provide a new way to predict the thermal effects of the crude oil pipeline in permafrost regions, and it shows that the standard deviations in temperature increase with time when considering the stochastic effect of soil properties and boundary conditions, which imply that the results of conventional deterministic analysis may be far from the true value, even if in different seasons. It can improve our understanding of the random temperature field of foundation soils surrounding the crude oil pipeline and provide a theoretical basis for actual engineering design in permafrost regions.",

"abstract": "Thermal gradient is one of the main features in artificial freezing ground and permafrost regions. The deformation and strength behavior of frozen soils with thermal gradient is of utmost importance for stabilities analysis of frozen engineering. A series of uniaxial compression tests were carried out on frozen saturated clay at various average temperatures and thermal gradients. The experimental results indicated that the uniaxial stress-strain curve for frozen clay with thermal gradient presents elastic-linear strain hardening characteristics, both the hardening modulus and uniaxial compression strength increase as the thermal gradient and average temperature decreased, but the elastic modulus varies little as the thermal gradient increased. The polygonal stress-strain constitutive equations were implemented into the FEM (Finite Element Method) and the local axial strain distribution of frozen clay with thermal gradient was studied. Two stages are observed from the curves describing the relationship between local axial strain and specimen height, i.e., increase stage and decrease stage for the slope of d. Characteristic parameters such as the demarcation height of Hd, the maximum slope of dmax are defined and analyzed. It is found that the characteristic parameters are all dependent on the thermal gradient and average temperature. The thermal gradient presents weakening effects to the local axial strain rate at middle specimen height of δεa,H=10'/δt in frozen clay with identical average temperature, and that further lead to the decrease of hardening modulus and uniaxial compression strength. © 2013 Elsevier Ltd.",

"abstract": "Abstract In cold regions, the temperature is important to determine the stability of tunnel construction. However, the conventional finite element methods for stability analysis are always deterministic, rather than taking stochastic parameters and conditions into account. In this paper, the boundary conditions are considered as stochastic processes and the rock properties are considered as random fields. A stochastic analysis for the uncertain temperature characteristics of tunnel is presented. The stochastic finite element formulae are obtained by Neumann stochastic finite element method (NSFEM), and the stochastic finite element program is compiled by Matrix Laboratory (MATLAB) software. Using our program, the random temperature fields of a tunnel in a cold region are obtained and analyzed. The results show that the temperature of a large quantity of frozen surrounding rock is stochastic, and it is bad for the thermal stability of actual tunnel engineering in cold regions. The distributions of mean temperature are the same and the distributions of standard deviation are similar for the two cases in this paper. The average standard deviation increases with time, which implies that the results of conventional deterministic analysis may be far from the true value. These results can improve our understanding of the random temperature field of tunnel and provide a theoretical basis for actual engineering design in cold regions.",

These stochastic parameters lead to the fact that conventional deterministic temperature field of embankment become stochastic. In order to estimate the influence of stochastic parameters on random temperature field for embankment in permafrost regions, a series of simulated tests are conducted in this study. We consider the soil properties as random fields and the upper boundary conditions as stochastic processes. Taking the variability of each stochastic parameter into account individually or concurrently, the corresponding random temperature fields are investigated by Neumann stochastic finite element method. The results show that both of the standard deviation under the embankment and the boundary increase with time when considering the stochastic effect of soil properties and boundary conditions. Stochastic boundary conditions and soil properties play a different role in random temperature field of embankment at different times. Each stochastic parameter has a different effect on random temperature field. These results can improve our understanding of the influence of stochastic parameters on random temperature field for embankment in permafrost regions.",

"abstract": "Abstract The uncertain thermal parameters of warm frozen soil are the key factors for computing the stochastic temperature field, and the spatial variability can lead to the randomness of thermodynamic characteristic. In this study, a series of thermal parameters tests for the warm frozen soil are carried out, and the thermal conductivity, heat capacity and thermal diffusivity for the different temperature (from −1.8 °C to 0 °C) are obtained. Then the variance function and the scale of fluctuation for the uncertain thermal parameters are estimated on the basis of the random field theory. The results shows that the variance functions for the thermal conductivity, heat capacity and thermal diffusivity decreased along with the increase of averaging distance. The scale of fluctuation for the thermal conductivity is between 0.96 m and 1.25 m under different freezing temperature condition; the scale of fluctuation for the heat capacity is between 0.88 m and 1.15 m, and the scale of fluctuation for the thermal diffusivity is between 0.75 m and 1.13 m. This study can improve our understanding of the spatial variation characteristics of uncertain thermal parameters for warm frozen soil and provide a theoretical basis and reference for the stochastic thermal analysis of frozen soil engineering.",

"title": "On the frost heaving-induced pressure response and its dropping power-law behaviors of freezing soils under various restraints",
"abstract": "Abstract A one-dimensional frost heave testing system is developed in this paper to investigate the frost heaving-induced pressure (FHIP) of frost susceptible silty clay under various restraints and thermal gradients. The evolution of the frost heave, the moisture migration, and the FHIP are examined from the conducted freezing tests, as well as the effects of restrained stiffness and thermal gradient. The development of frost heave can be divided into four stages, i.e. the constant temperature stage, the rapid development stage, the transition development stage, and the stable stage. For tests with − 20 °C at the cold end of the tested samples, the ultimate heave is 5.88 mm, 4.86 mm and 4.31 mm, and the FHIP is 65.0 kPa, 71.1 kPa and 92.1 kPa, corresponding to the restrained stiffness of 11.06 kPa/mm, 14.62 kPa/mm and 21.36 kPa/mm, respectively. It can be found that the frost heave decreases gradually with the restrained stiffness, whereas the FHIP shows an increase with the retrained stiffness. The results indicate that the FHIP drops rapidly with the relaxation of restraints, while this downward trend slows down as the frost heaving ratio increases. It is found that the FHIP decreases following an exponential function with the increase of frost heaving ratio, and the FHIP shows a dropping power-law behavior with an exponent of approximately 8/5.",

"abstract": "Abstract The mechanical characteristics of tunnels in cold regions are uncertain because of the randomness of temperature field and mechanical parameters. Conventional forecast analysis is always deterministic, rather than taking stochastic temperature and parameters into account. This paper aims to investigate the stochastic mechanical characteristics of tunnel in cold regions on the basis of a stochastic analysis model and stochastic finite element method. A series of computer codes is compiled by Matrix Laboratory (MATLAB) software, and the stochastic mechanical characteristics for a tunnel in a cold region are obtained and analyzed by Neumann stochastic finite element method (NSFEM). The results provide a new method to predict the uncertain mechanical characteristics of tunnel in cold regions, and it shows that the stochastic temperature has an effect on stochastic stress for surrounding rock, and the major principle stress and minor principle stress are changeable in different times. The frost heave of surrounding rock leads to the increase of mean stress and mean displacement for lining while the thawing process leads to the decline of mean stress and mean displacement for lining. With the passage of time, the stress standard deviation and displacement standard deviation for lining show an upward trend, which imply that the results of conventional deterministic analysis for mechanical characteristic of tunnel lining may be farther from the true value. These results can improve our understanding of the uncertainty mechanical characteristics for tunnel and provide a theoretical basis for engineering reliability analysis and design in cold regions.",

"title": "Cyclic direct shear behaviors of an artificial frozen soil-structure interface under constant normal stress and sub-zero temperature",
"abstract": "Abstract The soil-structure interface between structures and frozen soil ground is an important element to the structure safety in permafrost regions. This interface is usually subjected to a constant normal stress and cyclic shear loadings such as seismic, wind, and wave loadings. Hence, the cyclic direct shear behaviors of this interface have critical impacts on the safety and durability of the structure. This paper investigated the cyclic direct shear behaviors of an artificial frozen soil-structure interface under four constant normal stresses and four sub-zero temperatures by using a large-scale multi-functional direct shear apparatus. Cyclic shear stress and normal displacement were measured under normal stresses of 100, 300, 500, and 700 kPa and at sub-zero temperatures of − 2, − 6, − 10, and − 14 °C, respectively. These measurements revealed the following mechanical properties of this artificial interface: (1) The maximum shear stress is always observed in the initial stage of the first cycle. This maximum shear stress is linearly related to the normal stress. (2) Both the internal friction angle and the cohesion of this interface at the maximum shear stress decrease with the increase of sub-zero temperature. (3) The internal friction angle decreases with further cycles. This angle becomes significantly smaller in the stabilized cycles than that in the first cycle. (4) The maximum dilation measured by normal displacement is always observed in the first cycle. This dilation is decreasing with higher normal stress and at lower sub-zero temperature. However, the final normal displacement always contracts and its magnitude increases with the increase of normal stress or the decrease of sub-zero temperature. Finally, a simple damage model is proposed to describe these behaviors of this artificial interface and its performance is checked through its prediction for experimental data.",

"title": "Stochastic analysis of uncertain thermal parameters for random thermal regime of frozen soil around a single freezing pipe",
"abstract": "The artificial ground freezing method (AGF) is widely used in civil and mining engineering, and the thermal regime of frozen soil around the freezing pipe affects the safety of design and construction. The thermal parameters can be truly random due to heterogeneity of the soil properties, which lead to the randomness of thermal regime of frozen soil around the freezing pipe. The purpose of this paper is to study the one-dimensional (1D) random thermal regime problem on the basis of a stochastic analysis model and the Monte Carlo (MC) method. Considering the uncertain thermal parameters of frozen soil as random variables, stochastic processes and random fields, the corresponding stochastic thermal regime of frozen soil around a single freezing pipe are obtained and analyzed. Taking the variability of each stochastic parameter into account individually, the influences of each stochastic thermal parameter on stochastic thermal regime are investigated. The results show that the mean temperatures of frozen soil around the single freezing pipe with three analogy method are the same while the standard deviations are different. The distributions of standard deviation have a great difference at different radial coordinate location and the larger standard deviations are mainly at the phase change area. The computed data with random variable method and stochastic process method have a great difference from the measured data while the computed data with random field method well agree with the measured data. Each uncertain thermal parameter has a different effect on the standard deviation of frozen soil temperature around the single freezing pipe. These results can provide a theoretical basis for the design and construction of AGF.",

"title": "Stochastic Thermal-Mechanical Characteristics of Frozen Soil Foundation for a Transmission Line Tower in Permafrost Regions",
"abstract": "The Qinghai–Tibet Power Transmission Line (QTPTL), crossing about 550 km of permafrost region, was constructed between July 2010 and October 2011. The long-term thermal-mechanical stabilities attract extensive attention because of global warming and engineering activities. Conventional calculation and prediction of the thermal-mechanical characteristics of a frozen soil foundation for the QTPTL always involve deterministic analysis. This study aimed to investigate the uncertain thermal-mechanical characteristics of a transmission tower foundation by a stochastic analysis method. Considering the effect of stochastic temperature on the stochastic deformation, a stochastic coupling computer program was compiled. The random temperature fields and random deformation fields of foundation soils for a transmission line tower in a permafrost region were calculated and predicted for the next 30 years. This work provides a novel method to analyze the stochastic thermal-mechanical characteristics of a frozen soil foundation for a transmission line tower in permafrost regions. The average standard deviations of temperature grew from 1.1 to 1.6°C on January 15, and the maximum standard deviations of temperature were grew from 3.0 to 3.5°C. The average standard deviations of vertical displacement grew from 0.46 to 0.79 cm on January 15, and the maximum standard deviations of vertical displacement grew from 1.81 to 21.2 cm. The increase of standard deviations implies that the results of conventional prediction methods for temperature and deformation may be deviate from the exact value. These results can clarify the stochastic thermal-mechanical characteristics of frozen soil foundations for the QTPTL in permafrost regions.

"abstract": "AIM:To analyse the efficacy and complications of complicated primary rhegmatogenous retinal detachment(RRD) treated with minimal segmental scleral buckling surgery. ·METHODS:This retrospective study included 76 consecutive cases of RRD which were operated on between October 2006 and October 2008 at department of ophthalmology,Xi’an No.4 Hospital with minimal scleral buckling surgery. Complicated primary rhegmatogenous retinal detachment was limited to slit pore in 2 quadrant or over and grades of vitreoretinopathy in C1-C2. This surgery referred to segmental buckle limited only to the area of retinal breaks with puncture of anterior chamber,and laser photocoagulation after retinal reattachment. All cases were studied including age of onset,course of disease,the extent of retinal detachment,the number and shape of retinal break,pre-and postoperative visual acuity,reattachment rate of operation and reoperation,reoperative rate,and complications after operation.·RESULTS:The mean age of the subjects was 31.92 years(range,19-62 years) ,and the mean course of disease was 7.4 months(range,2.0-36.5 months) ,the mean number of the quadrant of retinal detachment was 3.33,every retina had about 3.43 breaks in average(range,2-7) .Postoperative visual acuity had been im-proved in 48 cases. The primary and additional reattach-ment rate was 84% and 93%,respectively. The additional surgery rate was 38%. There were 17 cases of subjects who had encountered the postoperative complications,which included temporary diplopia in 3 cases,temporary high level of IOP in 12 cases and macular oedema in 2 cases.·CONCLUSION:Compared with the documentation,the treatment of complicated RRD with minimal buckling surgery could achieve the same anatomical and functional results as cerclage surgery,but the former has a higher rate of additional surgery than the latter,which means that we should be careful in the choice of operation indication in the treatment of the complicated primary RRD by minimal buckling surgery.",

"abstract": "• Aim: To observe the calcium flux of human retinal pigment epithelial cells (RPEs) during mechanical stress in vitro. • Methods: Ferric oxide microparticles, coated with collagen, were added into dishes containing substrate-attached RPEs. After incubation, the cell layer bounded with beads was laid in invariable magnetic field. Cultured human RPE cells were analyzed by using the fluorescence Ca2+ dye fluo-3/AM and laser scanning confocal microscope (LSCM) before and after force stimulation. • Results: Normal fluorescence in RPE cells was strong and distributed throughout the cells. The nucleus appeared to be more fluorescent than the cytoplasm. After force stimulation, a rapid increase in fluorescence intensity was observed, followed by a rapid decrease by adding MnCl2. There was no obvious difference in increased curve in cells preincubated with EGTA. By adding CaCl2, the fluorescence intensity increased again. Moreover, after force stimulation, the fluorescence intensity in cells preincubated with cytochalasin D increased over twice than that in normal cells. • Conclusion: Mechanical stress may increase the calcium influx of RPEs and initiate the release of intracellular calcium store. The calcium influx may be a signal before RPEs injury.",

"abstract": "Objective To investigate the effects of defibrase drugs with light quantum on the changes in hemorrheologic behavior and the level of blood lipid for anterior ischemic optic neuropathy(AION) and central retinal vein occlusion (CRVO). Methods A total of 132 patients with AION and CRVO,selected from the center of the Fourth Hospital of Xi'an,were divided into two groups by hemorrheologic behavior,each group involved 66 patients,randomly divided into treatment and control groups and males and females.Several items of hemorheology in 132 cases (66 males and 66 females) were treated with different methods with same drug to ameliorate the abnormal hemorrheologic blood behavior.Sixty six patients were given difibrase 10 U in 5% glucose solution iv drip,qd. Sixty six patients were given same doses defibrase in 5% glucose solution iv drip,qd,and at the same time light quantum was used. Hematocrit(HCT),fibrinogen,cholesterol,triglyceride (TG) and other items were examined before and after the therapy.After 10 day treatment,the changes in hemorheology and blood lipid were observed and compared respectively in each pair.The results in different groups is analyzed retrospectively. Results Indices of hemorheology in different methods with same drug were markedly reduced (P<0.05).The effect of treatment groups with light quantum was greater than that of control group.The indices of hemorheology such as high-shearing viscosity,low- shearing viscosity,red cell hematocrit,fibrinogen,and total cholesterol of blood lipid,were with significant difference compared with those of control group before and after treatment(P<0.01 or<0.05). Conclusions The drug treatment with light quantum on high blood viscosity in comparison with the control group is different for abnor- mally hemorrheologic behavior recovery.Choosing light as the suitable method with same drug is better for the therapeutic efficacy on treating AION and CRVO.",

"abstract": "AIM: To evaluate the therapeutic effect of two-step laser-induced chorioretinal venous anastomosis (LCRVA) in the treatment of central retinal vein occlusion (CRVO). METHODS: CRVO model was made by the photodynamic method in 22 rabbits (44 eyes). After one eye of the rabbits was randomly selected, we used multiple-frequency Nd:YAG and YAG laser devices to rupture the Burch's membrane and the adjacent venous wall to build the anastomosis. Therapeutic effect was determined by the results of fundus fluorescein angiography (FFA) and histopathologic examination four months later. RESULTS: CRVO model was made successfully in 34 eyes (77.3%), and 17 of them were treated with LCRVA at two different sites. The result of FFA revealed that the functional anastomosis was established in 8 eyes(47%, 11 sites) after 3-5wk. At postoperative 4mo, comparing the results of FFA and histopathologic examination of different groups, the impairment to the retina in the group with anastomosis established was found to be slighter than that in the CRVO group. CONCLUSION: Two-step LCRVA is a feasible and effective way in treating CRVO, and the establishment of the by-pass drainage can postpone the progression of the disease.",

"abstract": "To investigate the regulatory effects of ninjurin-1 on adhesion of myeloid cells in the retina at the early stage of diabetic rats.Experimental study. The rat diabetic model was induced by intraperitoneal injection of streptozotocin. After 2 months of diabetes induction, 27 diabetic rats were randomly chosen and assigned to 3 groups, including diabetes and phosphate buffered saline (PBS) injection group (group B), diabetes and anti-Ninj-1 injection group (group C) and diabetes and anti-IgG injection group (group D), with 9 rats in each group. Nine age matched health rats were chosen as control group (group A). Retinal leukostasis was quantified with acridine orange leukocyte fluorography. Retinal myeloid cell infiltration activity was measured by enzyme linked immunosorbent assay of myeloperoxidase (MPO). The differences of the mean values among the four groups were analyzed by one-factor analysis of variance. The multiple comparisons of the mean values among the four groups were analyzed by LSD-t analysis.According to the results of the acridine orange leukocyte fluorography, the numbers of leukocyte adhesion in the four groups were 49.66 ± 13.51, 153.66 ± 20.43, 85.33 ± 15.03 and 156.33 ± 11.53, respectively. The differences among them were significant (F = 143.34, P = 0.000). The numbers of leukocyte adhesion in the group C were significantly lower than that in group B (P = 0.000, 95%CI: -82.68 - -53.98). The levels of retinal MPO in the four groups were (15.66 ± 2.08), (27.66 ± 2.51), (18.02 ± 2.01) and (26.66 ± 3.21) µg/L, respectively. The differences among them were significant (F = 17.61, P = 0.010). The level of retinal MPO in the group C was significantly lower than that in group B (P = 0.010, 95%CI: -14.37 - -4.95).Ninj-1 may play a role in the mediation of the adhesion of myeloid cell to the rat retina of early-stage of diabetes in vivo.",

"abstract": "Wind energy, which is intermittent by nature, can have a significant impact on power grid security, power system operation, and market economics, especially in areas with a high level of wind power penetration. Wind speed forecasting has been a vital part of wind farm planning and the operational planning of power grids with the aim of reducing greenhouse gas emissions. Improving the accuracy of wind speed forecasting algorithms has significant technological and economic impacts on these activities, and significant research efforts have addressed this aim recently. However, there is no single best forecasting algorithm that can be applied to any wind farm due to the fact that wind speed patterns can be very different between wind farms and are usually influenced by many factors that are location-specific and difficult to control. In this paper, we propose a new hybrid wind speed forecasting method based on a back-propagation (BP) neural network and the idea of eliminating seasonal effects from actual wind speed datasets using seasonal exponential adjustment. This method can forecast the daily average wind speed one year ahead with lower mean absolute errors compared to figures obtained without adjustment, as demonstrated by a case study conducted using a wind speed dataset collected from the Minqin area in China from 2001 to 2006.",

"abstract": "As a clean and renewable energy source, wind energy has been increasingly gaining global attention. Wind speed forecast is of great significance for wind energy domain: planning and design of wind farms, wind farm operation control, wind power prediction, power grid operation scheduling, and more. Many wind speed forecasting algorithms have been proposed to improve prediction accuracy. Few of them, however, have studied how to select input parameters carefully to achieve desired results. After introducing a Back Propagation neural network based on Particle Swam Optimization (PSO-BP), this paper details a method called IS-PSO-BP that combines PSO-BP with comprehensive parameter selection. The IS-PSO-BP is short for Input parameter Selection (IS)-PSO-BP, where IS stands for Input parameter Selection. To evaluate the forecast performance of proposed approach, this paper uses daily average wind speed data of Jiuquan and 6-hourly wind speed data of Yumen, Gansu of China from 2001 to 2006 as a case study. The experiment results clearly show that for these two particular datasets, the proposed method achieves much better forecast performance than the basic back propagation neural network and ARIMA model.",

"title": "Research and Application of a Novel Hybrid Model Based on Data Selection and Artificial Intelligence Algorithm for Short Term Load Forecasting.",
"abstract": "Machine learning plays a vital role in several modern economic and industrial fields, and selecting an optimized machine learning method to improve time series’ forecasting accuracy is challenging. Advanced machine learning methods, e.g., the support vector regression (SVR) model, are widely employed in forecasting fields, but the individual SVR pays no attention to the significance of data selection, signal processing and optimization, which cannot always satisfy the requirements of time series forecasting. By preprocessing and analyzing the original time series, in this paper, a hybrid SVR model is developed, considering periodicity, trend and randomness, and combined with data selection, signal processing and an optimization algorithm for short-term load forecasting. Case studies of electricity power data from New South Wales and Singapore are regarded as exemplifications to estimate the performance of the developed novel model. The experimental results demonstrate that the proposed hybrid method is not only robust but also capable of achieving significant improvement compared with the traditional single models and can be an effective and efficient tool for power load forecasting.",

"title": "A seasonal hybrid procedure for electricity demand forecasting in China",
"abstract": "Electricity is a special energy which is hard to store, so the electricity demand forecasting in China remains an important problem. This paper aims at developing an improved hybrid model for electricity demand in China, which takes the advantages of moving average procedure, combined method, hybrid model and adaptive particle swarm optimization algorithm, known as MA-C-WH. It is designed for making trend and seasonal adjustments which simultaneously presents the electricity demand forecasts. Four actual electricity demand time series in China power grids are selected to illustrate the proposed MA-C-WH model, and one existing seasonal autoregressive integrated moving average model (SARIMA) is selected to compare with the proposed model using the same data series. The results of popular forecasting precision indexes show that our proposed model is an effective forecasting technique for seasonal time series with nonlinear trend.",

"title": "The forecasting procedure for long-term wind speed in the Zhangye area",
"abstract": "Energy crisis has made it urgent to find alternative energy sources for sustainable energy supply; wind energy is one of the attractive alternatives. Within a wind energy system, the wind speed is one key parameter; accurately forecasting of wind speed can minimize the scheduling errors and in turn increase the reliability of the electric power grid and reduce the power market ancillary service costs. This paper proposes a new hybrid model for long-term wind speed forecasting based on the first definite season index method and the Autoregressive Moving Average (ARMA) models or the Generalized Autoregressive Conditional Heteroskedasticity (GARCH) forecasting models. The forecasting errors are analyzed and compared with the ones obtained from the ARMA, GARCH model, and Support Vector Machine (SVM); the simulation process and results show that the developed method is simple and quite efficient for daily average wind speed forecasting of Hexi Corridor in China.

"title": "Coal production forecast and low carbon policies in China",
"abstract": "With rapid economic growth and industrial expansion, China consumes more coal than any other nation. Therefore, it is particularly crucial to forecast China's coal production to help managers make strategic decisions concerning China's policies intended to reduce carbon emissions and concerning the country's future needs for domestic and imported coal. Such decisions, which must consider results from forecasts, will have important national and international effects. This article proposes three improved forecasting models based on grey systems theory: the Discrete Grey Model (DGM), the Rolling DGM (RDGM), and the p value RDGM. We use the statistical data of coal production in China from 1949 to 2005 to validate the effectiveness of these improved models to forecast the data from 2006 to 2010. The performance of the models demonstrates that the p value RDGM has the best forecasting behaviour over this historical time period. Furthermore, this paper forecasts coal production from 2011 to 2015 and suggests some policies for reducing carbon and other emissions that accompany the rise in forecasted coal production. © 2011 Elsevier Ltd.",

In order to prevent the overheating of real estate investment, this paper presents a pre-warning system developed to monitor and provide pre-warning to the governmental decision makers in real estate market. In the overall structure plan, the warning classification system is the most important so that we make an innovation to it using the novel ACO-PSO-hybrid algorithm. The hybrid algorithm makes use of advantages of both ACO and PSO methods therefore it is of benefit in solving clustering problems. And the experiment results demonstrate that our algorithm is significantly better than K-means methods in terms of quality. It is adaptive, robust and efficient, achieving high autonomy, simplicity and efficiency. Therefore it can effectively provide early warning corresponding to reality so that the pre-warning system can provide useful information to regulate the property market.",

"abstract": "In deregulated power markets, forecasting electricity loads is one of the most essential tasks for system planning, operation and decision making. Based on an integration of two machine learning techniques: a hybrid evolutionary algorithm which combines PSO and Artificial Fish Swarm Algorithm Search approach based on test-sample error estimate criterion (PSO-AFSAS-TEE) and support vector regression (SVR), this paper proposes a novel evolutionary model for future electricity load forecasting. The proposed evolutionary model adopts an integrated architecture to optimize the prediction of time series. Firstly, the theory of Phase Space Reconstruction (PSR) technique was used for nonlinear dynamic system analysis and prediction with the chaotic load series. Then, a PSO-AFSAS-TEE evolutionary system is proposed to choose the parameters of SVR automatically in time series prediction. The effectiveness of the proposed model is demonstrated with actual data taken from the Australia Power Grid.",

"abstract": "Electricity demand forecasting plays an important role in electric power systems planning. In this paper, nonlinear time series modeling technique is applied to analyze electricity demand. Firstly, the phase space, which describes the evolution of the behavior of a nonlinear system, is reconstructed using the delay embedding theorem. Secondly, the largest Lyapunov exponent forecasting method (LLEF) is employed to make a prediction of the chaotic time series. In order to overcome the limitation of LLEF, a weighted largest Lyapunov exponent forecasting method (WLLEF) is proposed to improve the prediction accuracy. The particle swarm optimization algorithm (PSO) is used to determine the optimal weight parameters of WLLEF. The trend adjustment technique is used to take into account the seasonal effects in the data set for improving the forecasting precision of WLLEF. A simulation is performed using a data set that was collected from the grid of New South Wales, Australia during May 14-18, 2007. The results show that chaotic characteristics obviously exist in electricity demand series and the proposed prediction model can effectively predict the electricity demand. The mean absolute relative error of the new prediction model is 2.48%, which is lower than the forecasting errors of existing methods.",

"abstract": "For an energy-limited economy system, it is crucial to forecast load demand accurately. This paper devotes to 1-week-ahead daily load forecasting approach in which load demand series are predicted by employing the information of days before being similar to that of the forecast day. As well as in many nonlinear systems, seasonal item and trend item are coexisting in load demand datasets. In this paper, the existing of the seasonal item in the load demand data series is firstly verified according to the Kendall τ correlation testing method. Then in the belief of the separate forecasting to the seasonal item and the trend item would improve the forecasting accuracy, hybrid models by combining seasonal exponential adjustment method (SEAM) with the regression methods are proposed in this paper, where SEAM and the regression models are employed to seasonal and trend items forecasting respectively. Comparisons of the quartile values as well as the mean absolute percentage error values demonstrate this forecasting technique can significantly improve the accuracy though models applied to the trend item forecasting are eleven different ones. This superior performance of this separate forecasting technique is further confirmed by the paired-sample T tests. © 2013 Elsevier B.V. All rights reserved.",

The adaptive fuzzy combination model can effectively count for electric load forecasting with good accuracy and interpretability at the same time. The key idea behind the combination is to build a human-understandable knowledge base by constructing a fuzzy membership function for each homogeneous sub-population.

Then these sub-series except the high frequency are forecasted respectively by FNN whose input variables are selected by using partial autocorrelation function (PACF). Finally, the prediction results of the modeled IMFs and residual series are summed to formulate an ensemble forecast for the original wind speed series.

"title": "Short-term wind speed forecasting based on a hybrid model",
"abstract": "Wind power is currently one of the types of renewable energy with a large generation capacity. However, operation of wind power generation is very challenging because of the intermittent and stochastic nature of the wind speed. Wind speed forecasting is a very important part of wind parks management and the integration of wind power into electricity grids. As an artificial intelligence algorithm, radial basis function neural network (RBFNN) has been successfully applied into solving forecasting problems. In this paper, a novel approach named WTT-SAM-RBFNN for short-term wind speed forecasting is proposed by applying wavelet transform technique (WTT) into hybrid model which hybrids the seasonal adjustment method (SAM) and the RBFNN. Real data sets of wind speed in Northwest China are used to evaluate the forecasting accuracy of the proposed approach. To avoid the randomness caused by the RBFNN model or the RBFNN part of the hybrid model, all simulations in this study are repeated 30 times to get the average. Numerical results show that the WTT-SAM-RBFNN outperforms the persistence method (PM), multilayer perceptron neural network (MLP), RBFNN, hybrid SAM and RBFNN (SAM-RBFNN), and hybrid WTT and RBFNN (WTT-RBFNN). It is concluded that the proposed approach is an effective way to improve the prediction accuracy.",

"abstract": "This paper presents an optimal training subset for support vector regression (SVR) under deregulated power, which has a distinct advantage over SVR based on the full training set, since it solves the problem of large sample memory complexity O(N^2) and prevents over-fitting during unbalanced data regression. To compute the proposed optimal training subset, an approximation convexity optimization framework is constructed through coupling a penalty term for the size of the optimal training subset to the mean absolute percentage error (MAPE) for the full training set prediction. Furthermore, a special method for finding the approximate solution of the optimization goal function is introduced, which enables us to extract maximum information from the full training set and increases the overall prediction accuracy. The applicability and superiority of the presented algorithm are shown by the half-hourly electric load data (48 data points per day) experiments in New South Wales under three different sample sizes. Especially, the benefit of the developed methods for large data sets is demonstrated by the significantly less CPU running time.",

"abstract": "Risk of lower respiratory diseases was significantly correlated with levels of monthly average concentration of SO 2; NO 2 and association rules have high lifts. In view of Lanzhou's special geographical location, taking into account the impact of different seasons, especially for the winter, the relations between air pollutants and the respiratory disease deserve further study. In this study the monthly average concentration of SO 2, NO 2, PM 10 and the monthly number of people who in hospital because of lower respiratory disease from January 2001 to December 2005 are grouped equidistant and considered as the terms of transactions. Then based on the relational algebraic theory we employed the optimization relation association rule to mine the association rules of the transactions. Based on the association rules revealing the effects of air pollutants on the lower respiratory disease, we forecast the number of person who suffered from lower respiratory disease by the group method of data handling (GMDH) to reveal the risk and give a consultation to the hospital in Xigu District, the most seriously polluted district in Lanzhou. The data and analysis indicate that individuals may be susceptible to the short-term effects of pollution and thus suffer from lower respiratory diseases and this effect presents seasonal. © 2012 Elsevier Ltd.",

"abstract": " High levels of air pollution may seriously affect people's living environment and even endanger their lives. In order to reduce air pollution concentrations, and warn the public before the occurrence of hazardous air pollutants, it is urgent to design an accurate and reliable air pollutant forecasting model. However, most previous research have many deficiencies, such as ignoring the importance of predictive stability, and poor initial parameters and so on, which have significantly effect on the performance of air pollution prediction. Therefore, to address these issues, a novel hybrid model is proposed in this study. Specifically, a powerful data preprocessing techniques is applied to decompose the original time series into different modes from low- frequency to high- frequency. Next, a new multi-objective algorithm called MOHHO is first developed in this study, which are introduced to tune the parameters of ELM model with high forecasting accuracy and stability for air pollution series prediction, simultaneously. And the optimized ELM model is used to perform the time series prediction. Finally, a scientific and robust evaluation system including several error criteria, benchmark models, and several experiments using six air pollutant concentrations time series from three cities in China is designed to perform a compressive assessment for the presented hybrid forecasting model. Experimental results indicate that the proposed hybrid model can guarantee a more stable and higher predictive performance compared to others, whose superior prediction ability may help to develop effective plans for air pollutant emissions and prevent health problems caused by air pollution.

"abstract": "Precise short-term load forecasting (STLF) plays a key role in unit commitment, maintenance and economic dispatch problems. Employing a subjective and arbitrary predictive step size is one of the most important factors causing the low forecasting accuracy. To solve this problem, the largest Lyapunov exponent is adopted to estimate the maximal predictive step size so that the step size in the forecasting is no more than this maximal one. In addition, in this paper a seldom used forecasting model, which is based on the non-linear fractal extrapolation (NLFE) algorithm, is considered to develop the accuracy of predictions. The suitability and superiority of the two solutions are illustrated through an application to real load forecasting using New South Wales electricity load data from the Australian National Electricity Market. Meanwhile, three forecasting models: the gray model, the seasonal autoregressive integrated moving average approach and the support vector machine method, which received high approval in STLF, are selected to compare with the NLFE algorithm. Comparison results also show that the NLFE model is outstanding, effective, practical and feasible. © 2012 Elsevier Ltd. All rights reserved.",

"abstract": "Grey system theory has been widely used to forecast the economic data that are often nonlinear, irregular, and nonstationary. Current forecasting models based on grey system theory could adapt to various economic time series data. However, these models ignored the importance of the model parameter optimization and the use of recent data, which lead to poor forecasting accuracy. In this article, we propose a novel forecasting model, called particle swarm optimization rolling grey model PSO-RGM1,1, based on a rolling mechanism GM with optimized parameters by using the particle swarm optimization algorithm. The simple model is shown to be very effective in forecasting the tertiary industry data sequences, which are short and noisy but regular in secular trend. The experimental results show that PSO-RGM1,1 outperforms other commonly used forecasting models on three real economic data sets. Our empirical study shows that PSO is found to be the best overall algorithm to optimize the parameter of RGM compared with other well-known metaheuristics. Furthermore, we evaluated other variant PSOs and found that single particle PSO outperforms others overall in terms of prediction accuracy, convergence speed, and degree of certainty.",

"title": "A Hybrid Forecasting Model Based on Bivariate Division and a Backpropagation Artificial Neural Network Optimized by Chaos Particle Swarm Optimization for Day-Ahead Electricity Price",
"abstract": "In the electricity market, the electricity price plays an inevitable role. Nevertheless, accurate price forecasting, a vital factor affecting both government regulatory agencies and public power companies, remains a huge challenge and a critical problem. Determining how to address the accurate forecasting problem becomes an even more significant task in an era in which electricity is increasingly important. Based on the chaos particle swarm optimization (CPSO), the backpropagation artificial neural network (BPANN), and the idea of bivariate division, this paper proposes a bivariate division BPANN (BD-BPANN) method and the CPSO-BD-BPANN method for forecasting electricity price. The former method creatively transforms the electricity demand and price to be a new variable, named DV, which is calculated using the division principle, to forecast the day-ahead electricity by multiplying the forecasted values of the DVs and forecasted values of the demand. Next, to improve the accuracy of BD-BPANN, chaos particle swarm optimization and BD-BPANN are synthesized to form a novel model, CPSO-BD-BPANN. In this study, CPSO is utilized to optimize the initial parameters of BD-BPANN to make its output more stable than the original model. Finally, two forecasting strategies are proposed regarding different situations.",

The support vector machine, a novel artificial intelligence-based method developed from statistical learning theory, is adopted herein to establish a short-term stage forecasting model. However, take the fact into account that demand signal is affected by variant random factors and behaves big uncertainty, the predicted accuracy of SVM is not approving when the data show great randomness. It is obligatory that we present Markov chain to improve the predicted accuracy of SVM. This combined model takes advantage of the high predictable power of SVM model and at the same time take advantage of the prediction power of Markov chain modeling on the discrete states based on the SVM modeling residual sequence.

Moreover, the great difficulty of the subject is caused by both the external environment and the internal mechanism. In the external, owing to limit of impersonal condition, such as, realistic disturbance from noise signal can not avoid. In the internal, the masking effect appears in outlying observation so as to produce some unreasonable results by data analysis. Therefore, based not only on the requirement of external quality assurance schemes, but also on internal quality control where screening for outliers should probably be part of the procedure for our main goal. As a consequence, we have applied data accumulated generating operation and sample median test for solving the conundrum.",

"abstract": "Short-term electricity demand forecasting for the next hour to several days out is one of the most important tools by which an electric utility plans and dispatches the loading of generating units in order to meet system demand. But there exists chaos in electricity systems to a great extent. Complicated electricity systems are nonlinear systems and the forecasting is very complex in nature and quite hard to solve by conventional algorithm. The inaccuracy or large error in the forecast simply means that load matching is not optimized and consequently the generation and transmission systems are not being operated in an efficient manner. In this paper, feedforward neural network trained by fuzzy adaptive PSO algorithm is proposed for chaotic load time series global prediction. The results which are compared with feedforward neural network trained by Levenberg-Marquardt back-propagation (LMBP) algorithm show much more satisfactory performance, converges quickly towards the optimal position, convergent accuracy and can avoid overfitting in some extent.",

"title": "A Novel System for Wind Speed Forecasting Based on Multi-Objective Optimization and Echo State Network",
"abstract": "Given the rapid development and wide application of wind energy, reliable and stable wind speed forecasting is of great significance in keeping the stability and security of wind power systems. However, accurate wind speed forecasting remains a great challenge due to its inherent randomness and intermittency. Most previous researches merely devote to improving the forecasting accuracy or stability while ignoring the equal significance of improving the two aspects in application. Therefore, this paper proposes a novel hybrid forecasting system containing the modules of a modified data preprocessing, multi-objective optimization, forecasting, and evaluation to achieve the wind speed forecasting with high precision and stability. The modified data preprocessing method can obtain a smoother input by decomposing and reconstructing the original wind speed series in the module of data preprocessing. Further, echo state network optimized by a multi-objective optimization algorithm is developed as a predictor in the forecasting module. Finally, eight datasets with different features are used to validate the performance of the proposed system using the evaluation module. The mean absolute percentage errors of the proposed system are 3.1490%, 3.0051%, 3.0618%, and 2.6180% in spring, summer, autumn, and winter, respectively. Moreover, the interval prediction is complemented to quantitatively characterize the uncertainty as developing intervals, and the mean average width is below 0.2 at the 95% confidence level. The results demonstrate the proposed forecasting system outperforms other comparative models considered from the forecasting accuracy and stability, which has great potential in the application of wind power systems.",

"title": "Performance analysis of four modified approaches for wind speed forecasting",
"abstract": "Providing accurate wind speed prediction algorithms has become increasingly significant because of the important technological and economic impacts of wind speed on wind power generation. In this study, two combined strategies for wind speed forecasting are proposed and followed. Four approaches derived from these strategies are employed. The first two approaches employ Particle Swarm Optimization (PSO) to optimize the parameters in the first-order and second-order adaptive coefficient (FAC and SAC) methods. The remaining two approaches employ the decomposition of wind speed data into seasonal and trend components. The seasonal component is represented by the seasonal exponential adjustment, and the trend component is predicted by the hybrid models of PSO and FAC or SAC. By employing these four approaches, the daily mean wind speed is forecasted for four observation sites in Gansu, China. Multiple evaluation methods are used to assess forecasting quality: the mean square error, the mean absolute percentage error and the relative error. It is found that all four approaches better predict wind speed than the original FAC and SAC models. © 2012 Elsevier Ltd.",

"abstract": "In recent years, the multilayer feedforward neural network (FNN) has been received considerable attention and have been extensively used in many fields. Levenberg-Marquardt back-propagation (LMBP) algorithm as an FNN training method has some limitations associated with overfitting, local optimum problems and slow convergence rate. In order to overcome the limitations, some people proposed particle swarm optimization (PSO) as an evolutionary algorithm to train the FNN. But PSO has disadvantages such as low precision, slow convergence in the later stage of the evolution, and parameter selection problems. In this paper, a novel hybrid evolutionary algorithm based on AFSA and PSO, also referred to as AFSA-PSO-parallel-hybrid evolutionary (APPHE) algorithm, has been used in FNN training. Compared to FNN trained by LMBP algorithm, FNN training by the novel hybrid evolutionary algorithm show satisfactory performance, converges quickly towards the optimal position, convergent accuracy, high stability and can avoid overfitting in some extent. FNN training by the novel method has been testified by using in Iris data classification and the rusults are much more accurate and stable than by Levenberg-Marquardt back-propagation algorithm. © 2008 IEEE.",

We use one-order moving averages to produce a comparatively smooth data series, taking the averaging period as the interval that can effectively eliminate the seasonal variation. We used the smoothed data series as the training set input for the ε -SVR model and obtained the corresponding forecasting value. Afterward, we accounted for the previously removed seasonal variation. As a case, we forecast northeast electricity demand of China using the new method. We demonstrated that this simple procedure has very satisfactory overall performance by an analysis of variance with relative verification and validation. Significant reductions in forecast errors were achieved.",

"abstract": "In the last decade, the use of artificial neural networks (ANN) has become widely accepted in medical applications for accuracy for predictive inference, with potential to support and flexible non-linear modelling of large data sets. Feedforward neural network (FNN) is a kind of artificial neural networks, which has a better structure and been widely used. But there are still many drawbacks if we simply use feedforward neural network, such as slow training rate, easy to trap into local minimum point, and bad ability on global search. In this paper, feedforward neural network trained by fuzzy adaptive particle swarm optimization (FPSO) algorithm is proposed for breast cancer diagnosis. The results which are compared with FNN trained by PSO algorithm show much more accurate and stable, converges quickly towards the optimal position and can avoid overfitting in some extent. In the computer-aided decision systems, the accurate and stable computer algorithms are very important to help a physician in diagnosing a patient.",

Then, the need of sharing information from different sources is an obvious consequence from such proliferation of systems. Unfortunately, integrating supply chain information is not a trivial issue, because data and knowledge exchange among users of supply chain information systems presents many challenges. We must deal with the heterogeneity problem, which increase complexity of integration approaches. This paper discusses issues related to the use of ontologies in the development of supply chain information systems and proposes the creation of software components from diverse ontologies as a way to share data and supply chain information.

For improving an accuracy of prediction, in this paper, we adopt the theory of Grey prediction to develop a new forecasting approach that integrates historical data of the gross domestic products (GDP) into an electric capacity forecasting. We adopted Grey prediction as a forecasting means because of its fast calculation with as few as four data inputs needed. As a result, our study considered that Wu and Chen proposed a modeling method of the improved grey relational analysis and main shows that the general Grey model, GM (1, 1), which is an especial case, is adequate to handle an electrical power system. In this study, the prediction is improved significantly by applying the transformed Grey model and the concept of average system slope. The adaptive value of a in the Grey differential equation is obtained quickly with the average system slope technique. In such a way, the wastage of electric consumption can be avoided. That is, it is another achievement of virtual electric power plant. ©2008 IEEE.",

"title": "Application of residual modification approach in seasonal ARIMA for electricity demand forecasting: A case study of China",
"abstract": "Electricity demand forecasting could prove to be a useful policy tool for decision-makers; thus, accurate forecasting of electricity demand is valuable in allowing both power generators and consumers to make their plans. Although a seasonal ARIMA model is widely used in electricity demand analysis and is a high-precision approach for seasonal data forecasting, errors are unavoidable in the forecasting process. Consequently, a significant research goal is to further improve forecasting precision. To help people in the electricity sectors make more sensible decisions, this study proposes residual modification models to improve the precision of seasonal ARIMA for electricity demand forecasting. In this study, PSO optimal Fourier method, seasonal ARIMA model and combined models of PSO optimal Fourier method with seasonal ARIMA are applied in the Northwest electricity grid of China to correct the forecasting results of seasonal ARIMA. The modification models forecasting of the electricity demand appears to be more workable than that of the single seasonal ARIMA. The results indicate that the prediction accuracy of the three residual modification models is higher than the single seasonal ARIMA model and that the combined model is the most satisfactory of the three models. © 2012 Elsevier Ltd.",

"abstract": "Abstract Combination models are regarded as a popular approach to improve forecasting accuracy. Determining how to select optimal sub-models from all possible candidate models is considered to be a challenge in combination models because of the high computational overhead. However, there is fewer studies on sub-models selection for combination approaches. To this end, this study proposes a novel sub-models selection algorithm named neighborhood mutual information (NMI) theory-based maximizing linear relevance and minimizing linear redundancy (NMI-MRMR) to select the optimal sub-models set. Cuckoo search (CS) is used to find the optimal parameter of a neighborhood for the proposed algorithm by avoiding the evaluation of all possible parameters. Three cases are used to validate the performance of the proposed approach. The experimental forecasting results demonstrate that the combination of the individual models selected by the NMI-MRMR based CS algorithm significantly outperforms the combination of the individual models selected by traditional approaches. Furthermore, a comparison with two other artificial intelligence algorithms and a traversal algorithm indicate that the CS algorithm is more suitable for choosing the optimal parameter for the proposed algorithm. The proposed approach not only overcomes the shortcomings of combining all individual models but is also able to select the optimal sub-models set.",

ARMA is a popular method to analyze stationary univariate time series data. Stationarity checking, model identification, model estimation and model checking are usually four main stages to build an ARMA model and model identification is the most important stage in building ARMA models. However there is no method suitable for ARMA model that can overcome the problem of local optima, which is suitable for any ARMA model. The effectiveness of PSO Algorithm which is used to choose the parameters of ARMA Model automatically is tested for ARMA (2,2) model example. The identification of model ARMA(2,2): xt +0.1xt-1-0.2xt-2 = at+0.2at-1-0.5at-2. The simulation shows that the PSO-based model identification method can present better solutions than the MINIC model identification method.",

"abstract": "Electricity price forecasting holds very important position in the electricity market. Inaccurate price forecasting may cause energy waste and management chaos in the electricity market. However, electricity price forecasting has always been regarded as one of the largest challenges in the electricity market because it shows high volatility, which makes electricity price forecasting difficult. This paper proposes the use of artificial intelligence optimization combination forecasting models based on preprocessing data, called \"chaos particles optimization (CPSO) weight-determined combination models.\" These models allow for the weight of the combined model to take values of [-1, 1]. In the proposed models, the density-based spatial clustering of applications with noise (DBSCAN) algorithm is used to identify outliers, and the outliers are replaced by a new data-produced linear interpolation function. The proposed CPSO weight-determined combination models are then used to forecast the projected future electricity price. In this case study, the electricity price data of South Australia are simulated. The results indicate that, while the weight of the combined model takes values of [-1, 1], the proposed combination model can always provide adaptive, reliable, and comparatively accurate forecast results in comparison to traditional combination models.",

"title": "Forecasting wind speed using empirical mode decomposition and Elman neural network",
"abstract": "Because of the chaotic nature and intrinsic complexity of wind speed, it is difficult to describe the moving tendency of wind speed and accurately forecast it. In our study, a novel EMD-ENN approach, a hybrid of empirical mode decomposition (EMD) and Elman neural network (ENN), is proposed to forecast wind speed. First, the original wind speed datasets are decomposed into a collection of intrinsic mode functions (IMFs) and a residue by EMD, yielding relatively stationary sub-series that can be readily modeled by neural networks. Second, both IMF components and residue are applied to establish the corresponding ENN models. Then, each sub-series is predicted using the corresponding ENN. Finally, the prediction values of the original wind speed datasets are calculated by the sum of the forecasting values of every sub-series. Moreover, in the ENN modeling process, the neuron number of the input layer is determined by a partial autocorrelation function. Four prediction cases of wind speed are used to test the performance of the proposed hybrid approach. Compared with the persistent model, back-propagation neural network, and ENN, the simulation results show that the proposed EMD-ENN model consistently has the minimum statistical error of the mean absolute error, mean square error, and mean absolute percentage error. Thus, it is concluded that the proposed approach is suitable for wind speed prediction.",

However, the fluctuation of electricity price depends on the common effect of many factors and there is a very complicated random in its evolution process. Therefore, it is difficult to forecast half-hourly prices with traditional only one model for different behaviors of half-hourly prices.

"abstract": "For accurate electricity demand forecasting, this paper proposes a novel approach, MFES, that combines a multi-output FFNN (feedforward neural network) with EMD (empirical mode decomposition)-based signal filtering and seasonal adjustment. In electricity demand forecasting, noise signals, caused by various unstable factors, often corrupt demand series. To reduce these noise signals, MFES first uses an EMD-based signal filtering method which is fully data-driven. Secondly, MFES removes the seasonal component from the denoised demand series and models the resultant series using FFNN model with a multi-output strategy. This multi-output strategy can overcome the limitations of common multi-step-ahead forecasting approaches, including error amplification and the neglect of dependency between inputs and outputs. At last, MFES obtains the final prediction by restoring the season indexes back to the FFNN forecasts. Using the half-hour electricity demand series of New South Wales in Australia, this paper demonstrates that the proposed MFES model improves the forecasting accuracy noticeably comparing with existing models. © 2012 Elsevier Ltd.",

"abstract": "Optimum prediction is a difficult problem, because there are no optimal models for all forecasting problems. In this paper, the authors attempt to find the high precision prediction for grey forecasting model (GM). Considering that chaotic particle swarm optimization algorithm (CPSO) will not get into local optimum and is easy to implement, the paper develops an approach for grey forecasting model, which is particularly suitable for small sample forecasting, based on chaotic particle swarm optimization and optimal input subset which is a new concept. The input subset of traditional time series consists of the whole original data, but the whole original does not always reflect the internal regularity of time series, so the new optimal subset method is proposed to better reflect the internal characters of time series and improve the prediction precision. The numerical simulation result of financial revenue demonstrates that developed algorithm provides very remarkable results compared to traditional grey forecasting model for small dataset forecasting.",

"title": "Multistep Forecasting for Short-Term Wind Speed Using an Optimized Extreme Learning Machine Network with Decomposition-Based Signal Filtering",
"abstract": "Since wind fluctuates with strong variation even within a short-term period, it is quite difficult to describe the characteristics of wind or to estimate the power output that will be injected into the grid. In particular, short-term wind speed forecasting, an essential support for regulatory actions and short-term load dispatching planning during the operation of wind farms, is currently regarded as one of the most difficult problems to solve. This paper contributes to multistep forecasting for short-term wind speed by developing a three-stage hybrid approach named MECE; it is a combination of the ensemble empirical model decomposition (EEMD) method, cuckoo search (CS) algorithm, and extreme learning machine (ELM) method. As the first stage of the hybrid MECE approach, a signal filtering based on a decomposition and reconstruction strategy is adopted and copied by the EEMD method, and a denoised series can be obtained. Then, the CS-optimized ELM is designed as a novel learning method to construct a single layer feed-forward neural network (SLFN); the input weights and biases are determined by the CS algorithm instead of the random initialization within the original ELM. Next, a training and forecasting stage is taken; three different strategies are adopted for multistep forecasting. The chosen data sets are half-hour wind speed observations, including 16 samples, and the simulation indicates that the proposed MECE approach performs much better than the traditional ones when addressing short-term wind speed forecasting problems.",

"abstract": "Abstract Accurate and stable annual electricity consumption forecasting play vital role in modern social and economic development through providing effective planning and guaranteeing a reliable supply of sustainable electricity. However, establishing a robust method to improve prediction accuracy and stability simultaneously of electricity consumption forecasting has been proven to be a highly challenging task. Most previous researches only pay more attention to enhance prediction accuracy, which usually ignore the significant of forecasting stability, despite its importance to the effectiveness of forecasting models. Considering the characteristics of annual power consumption data as well as one criterion i.e. accuracy or stability is insufficient, in this study a novel hybrid forecasting model based on an improved grey forecasting mode optimized by multi-objective ant lion optimization algorithm is successfully developed, which can not only be utilized to dynamic choose the best input training sets, but also obtain satisfactory forecasting results with high accuracy and strong ability. Case studies of annual power consumption datasets from several regions in China are utilized as illustrative examples to estimate the effectiveness and efficiency of the proposed hybrid forecasting model. Finally, experimental results indicated that the proposed forecasting model is superior to the comparison models.",

However, current forecasting models ignore the importance of model parameter optimisation and the use of recent data. In this article, a novel forecasting approach with a Bayesian-regularised artificial neural networks (BR-ANN) was proposed. The weight of the proposed model (BR-ANN) is determined by the particle swarm optimisation (PSO) algorithm. Daily market prices and financial technical indicators are utilised as inputs to predict the one day future closing price of the Shanghai (in China) composite index. The Bayesian-regularised network uses a probabilistic nature for the network weights and can reduce the potential for over-fitting and over-training.

Big data mining, analysis and forecasting always play a vital role in modern economic and industrial fields, and selecting an optimization model to improve time series forecasting accuracy is challenging. A support vector regression (SVR) model is widely used forecasting and data processing, but the individual SVR cannot always satisfy the requirements of time series forecasting. In this paper, a hybrid v-SVR model is developed and combined with principal component analysis (PCA) and brain storm optimization (BSO) for stock price index forecasting. Correlation analysis and PCA are conducted initially to select the input variables of the v-SVR from 20 technical indicators, while the advanced BSO algorithm is used to search for optimal parameters of v-SVR. Case studies of the China Securities Index 300 (CSI300) and the Shenzhen Stock Exchange Component Index (SZSE Component Index) are examined as illustrative examples to evaluate the effectiveness and efficiency of the developed hybrid forecast strategy. Numerical results indicate that the developed hybrid model is not only simple but also able to satisfactorily approximate the actual CSI300stock price index, and it can be an effective tool in stock market mining and analysis.",

"abstract": "Abstract With the haze pollution occurred frequently in recent years, establishing an effective air quality early-warning system has become the top priority. Nowadays, researchers have provided numerous methods for air quality early-warning. However, the majority of studies ignores the significance of data preprocessing and air quality evaluation while designing an early-warning system, which leads to poor forecasting performance and insufficient information. A novel hybrid air quality early-warning system that consists of three modules: data preprocessing, forecasting and air quality evaluation module is designed in this paper. Aiming at extract chaotic characteristics of raw data, a new hybrid data preprocessing strategy is firstly developed to construct a more stable series of pollutant data for forecasting. Then a multi-objective grasshopper optimization algorithm is adopted in order to enhance the forecasting capability of accuracy and stability in the forecasting module. Moreover, a fuzzy evaluation module of air quality is proposed to provide comprehensive results for the system. Through the eighteen data sets’ experimental process, the results and discussions indicate that not only the forecasting method achieves higher accuracy and stronger stability than other comparison models, but also the evaluation module provides sufficient air quality information, which forms a scientific guidance to decision-makers against air pollution.",

Big data mining, analysis, and forecasting always play a vital role in modern economic and industrial fields. Thus, how to select an optimization model to improve the forecasting accuracy of electricity price is not only an extremely challenging problem but also a concerned problem for different participants in an electricity market due to our society becoming heavily reliant on electricity. Many researchers developed hybrid models through the use of optimization methods, classical statistical models, artificial intelligence approaches and de-noising methods. However, few researchers aim to select reasonable samples and determine appropriate features when forecasting electricity price. Based on the Index of Bad Samples Matrix (IBSM), a novel method to dynamically confirm bad training samples, and the Optimization Algorithm (OA), DCANN and Updated DCANN are proposed in this paper for forecasting the day-ahead electricity price. This model is a hybrid system of supervised and unsupervised learning and creatively applies the idea of deleting bad samples and searching quality inputs to develop and learn, which is unlike BPANN, RBFN, SVM and LSSVM. Numerical results show that the proposed model is not only able to approximate the actual electricity price (normal or high volatility) but also an effective tool for h-step-ahead forecasting (h is less than 10) compared to benchmarks.",

Wind energy has been gaining increasing global attention, and wind speed forecasting plays a vital role in the wind energy field. However, such forecasting has been demonstrated to be a challenging task due to the effect of various meteorological factors. This study proposes a hybrid forecasting model that can effectively provide preprocessing for the original data and improve forecasting accuracy. The developed model applies a genetic algorithm-adaptive particle swarm optimisation algorithm to optimise the parameters of the wavelet neural network (WNN) model. The proposed hybrid method is subsequently examined in regard to the wind farms of eastern China. The forecasting performance demonstrates that the developed model is better than some traditional models (for example, back propagation, WNN, fuzzy neural network, and support vector machine), and its applicability is further verified by the paired-sample T tests.",

"title": "A Novel Framework of Reservoir Computing for Deterministic and Probabilistic Wind Power Forecasting",
"abstract": "The path towards wind power forecasting has yielded huge socio–economic benefits at a global scale. However, most of the previous studies tend to emphasize the improvement of deterministic forecasting, usually losing sight of the significance of probabilistic forecasting. In this paper, a novel forecasting system that can perform deterministic and probabilistic forecasting of wind power simultaneously, composed by the modules of feature selection, forecasting, system optimization, and system evaluation is presented to further supplement the existing studies in this field. Concretely, a hybrid feature selection strategy is proposed in the feature selection module to determine optimal system input; superior to traditional gradient descent algorithm, a dynamic reservoir theory-based recurrent neural network is developed in the forecasting module; an enhanced multi-objective optimization algorithm with the objectives of accuracy and stability is proposed in the system optimization module to provide an optimal scenario for system parameters; the effectiveness and feasibility of the proposed system is then validated in the evaluation module. Moreover, the comprehensive performance analysis of the proposed system is investigated in depth. Finally, the experimental results demonstrate that the proposed system has a significant advantage over the benchmarks considered, further verifying its tremendous potential to be used in a practical wind power system.",

"title": "Developing an early-warning system for air quality prediction and assessment of cities in China",
"abstract": "An early-warning system is developed for air quality.Pollutant emission characteristics are analyzed using distribution functions.Dynamic forecast intervals are constructed for addressing the uncertainty.Air quality is evaluated by integrating fuzzy set theory and AHP.The results show that the developed early-system is effective and reliable. Air quality has received continuous attention from both environmental managers and citizens. Accordingly, early-warning systems for air pollution are very useful tools to avoid negative health effects and develop effective prevention programs. However, developing robust early-warning systems is very challenging, as well as necessary. This paper develops a reliable and effective early-warning system that consists of air quality prediction and assessment modules. In the prediction module, a hybrid forecasting method is developed for predicting pollutant concentrations that effectively estimates future air quality conditions. In developing this proposed model, we suggest the use of a back propagation neural network algorithm, combined with a probabilistic parameter model and data preprocessing techniques, to address the uncertainties involved in future air quality prediction. Meanwhile, a pre-analysis is implemented, primarily by using optimized distribution functions to examine and analyze statistical characteristics and emission behaviors of air pollutants. The second method, which is developed as part of the second module, is based on fuzzy set theory and the Analytic Hierarchy Process, and it performs air quality assessments to provide a clear and intelligible description of air quality conditions. Using data from the Ministry of Environmental Protection of China and six stages of air quality classification levels, specifically good, moderate, lightly polluted, moderately polluted, heavily polluted and severely polluted, two cities in China, Chengdu and Hangzhou, are used as illustrative examples to verify the effectiveness of the developed early-warning system. The results demonstrate that the proposed methods are effective and reliable for use by environmental supervisors in air pollution monitoring and management.",

"title": "Research on a combined model based on linear and nonlinear features - A case study of wind speed forecasting",
"abstract": "As one of the most promising sustainable energy sources, wind energy is being paid more attention by the researchers. Because of the volatility and instability of wind speed series, wind power integration faces a severe challenge; thus, an accurate wind energy forecasting plays a key role in smart grid planning and management. However, many traditional forecasting models do not consider the necessity and importance of data preprocessing and neglect the limitation of using a single forecasting model, which leads to poor forecasting accuracy. To solve these problems, a novel combined model based on two linear and four nonlinear forecasting algorithms is proposed to adapt both the linear and nonlinear characteristics of the wind energy time series. In addition, a modified Artificial Fish Swarm Algorithm and Ant Colony Optimization (AFSA-ACO) algorithm is proposed and employed to determine the optimal weight coefficients of the combined models. To verify the forecasting performance of the developed combined model, several experiments were implemented by using 10-min interval wind speed data in Shandong, China. Then, one-step (10-min), three-step (30-min) and five-step (50-min) predictions were conducted. The experimental results indicate that the developed combined model is remarkably superior to all benchmark models for the high precision and stability of wind-speed predictions.",

"abstract": "Abstract Electricity price forecasting is an important and challenging issue for all participants in the power market because of the wide application of electricity in our society and its inherent features. In this context, some current forecasting systems use data preprocessing and optimization for theoretical and practical achievements. However, some limitations to these systems exist which need to be urgently solved. First, future information is overdrawn in the data preprocessing stage of these forecasting systems, which is actually unknown in practical applications. The crucial question, therefore, is how to develop a forecasting system without using any future information. Second, the complex features of original nonlinear and nonstationary electricity price have a negative influence on the generalization ability of these previously developed models. To decrease the negative effects on management, a method to develop a forecasting system to improve the model’s generalization ability is required. Therefore, in this study, we developed an adaptive deterministic and probabilistic interval forecasting system for multi-step electricity price forecasting, which can present more valuable information to power market decision makers. Two cases and one comparative study are provided and analyzed to validate the performance of the developed system in multi-step electricity price forecasting. Furthermore, further discussions are presented to illustrate the significance of this study, thus proving that the results of the present study fill the present knowledge gap and provide some new future directions for related studies.",

"abstract": "Abstract Wind energy is attracting more attention with the growing demand for energy. However, the efficient development and utilization of wind energy are restricted due to the intermittency and randomness of wind speed. Although abundant investigations concerning wind speed forecasting have been conducted by numerous researchers, most of the studies merely attach importance to point forecasts, which cannot quantitatively characterize the uncertainties as developing intervals. In this study, a novel interval prediction architecture has been designed, aiming at constructing effective prediction intervals for a wind speed series, composed of a preprocessing module, a feature selection module, an optimization module, a forecast module and an evaluation module. The feature selection module, in cooperation with the preprocessing module, is developed to determine the optimal model input. Furthermore, the forecast module optimized by the optimization module is considered a predictor for giving prediction intervals. The experimental results shed light on the architecture that not only outperforms the benchmark models considered, but also has great potential for application to wind power systems.",

"abstract": "Abstract With atmospheric environmental pollution becoming increasingly serious, developing an early warning system for air quality forecasting is vital to monitoring and controlling air quality. However, considering the large fluctuations in the concentration of pollutants, most previous studies have focused on enhancing accuracy, while few have addressed the stability and uncertainty analysis, which may lead to insufficient results. Therefore, a novel early warning system based on fuzzy time series was successfully developed that includes three modules: deterministic prediction module, uncertainty analysis module, and assessment module. In this system, a hybrid model combining the fuzzy time series forecasting technique and data reprocessing approaches was constructed to forecast the major air pollutants. Moreover, an uncertainty analysis was generated to further analyze and explore the uncertainties involved in future air quality forecasting. Finally, an assessment module proved the effectiveness of the developed model. The experimental results reveal that the proposed model outperforms the comparison models and baselines, and both the accuracy and the stability of the developed system are remarkable. Therefore, fuzzy logic is a better option in air quality forecasting and the developed system will be a useful tool for analyzing and monitoring air pollution.",

"abstract": "This paper discusses the history and present status of different categories of biogas production in China, most of which are classified into rural household production, agriculture-based engineering production, and industry-based engineering production. To evaluate the future biogas production of China, five models including the Hubbert model, the Weibull model, the generalized Weng model, the H–C–Z model, and the Grey model are applied to analyze and forecast the biogas production of each province and the entire country. It is proved that those models which originated from oil research can also be applied to other energy sources. The simulation results reveal that China’s total biogas production is unlikely to keep on a fast-growing trend in the next few years, mainly due to a recent decrease in rural household production, and this greatly differs from the previous goal set by the official department. In addition, China’s biogas production will present a more uneven pattern among regions in the future. This paper will give preliminary explanation for the regional difference of the three biogas sectors and propose some recommendations for instituting corresponding policies and strategies to promote the development of the biogas industry in China.",

In recent years, neural networks are utilized in time series forecasting owing to the rationality and practicability. However, neural networks always overrate the performance of training data, which results in underestimating the test error. In this work, four important training tactics are proposed for the training and modeling of the networks, which promote forecasting percentages of the convolutional networks and get a better extrapolation performance. The numerical simulation shows that the proposed methods have broader application in time series forecasting, it is not only effective for over-fitting problems but also has promoted the model accuracy considerably.",

"abstract": "Abstract Wind energy prediction has a significant effect on the planning, economic operation and security maintenance of the wind power system. However, due to the high volatility and intermittency, it is difficult to model and predict wind power series through traditional forecasting approaches. To enhance prediction accuracy, this study developed a hybrid model that incorporates the following stages. First, an improved complete ensemble empirical mode decomposition with adaptive noise technology was applied to decompose the wind energy series for eliminating noise and extracting the main features of original data. Next, to achieve high accurate and stable forecasts, an improved wavelet neural network optimized by optimization methods was built and used to implement wind energy prediction. Finally, hypothesis testing, stability test and four case studies including eighteen comparison models were utilized to test the abilities of prediction models. The experimental results show that the average values of the mean absolute percent errors of the proposed hybrid model are 5.0116% (one-step ahead), 7.7877% (two-step ahead) and 10.6968% (three-step ahead), which are much lower than comparison models.",

In this paper, we intend to predict Beijingu0027s tertiary industry, whose datasets are small, irregular and non-stationary, leading to a difficulty of building an accurate prediction model. To this end, we present an improved grey model, named PRGM(1,1), which extends the grey prediction model by integrating two techniques, i.e., the particle swarm optimization algorithm for parameter optimization and the exponential preprocessing method for data cleaning. The experimental results show that PRGM(1,1) outperforms other variants of the grey prediction model in predicting Beijingu0027s tertiary industry, and is viable to do reasonable prediction over short and fluctuated economic data sequences. In addition, we employ PRGM(1,1) in the economic prediction of Beijingu0027s tertiary industry in the next five years, and conclude that the growth rate will decelerate. Our prediction result seems to be in line with the economic slowdown in China this year.",

"abstract": "Abstract Accurate and stable wind speed forecasting is a crucial issue in the wind power industry, which has a significant effect on power system operation, power grid security and market economics. However, most prior articles only attach importance to improving the accuracy or stability, few of them focus on the accuracy and stability, simultaneously. Therefore, considering one criterion i.e. accuracy or stability is insufficient, in this study a novel powerful hybrid forecasting system is successfully developed, which contains four modules: data preprocessing module, optimization module, forecasting module and evaluation module. In this system, decomposing algorithm is applied to divide the original wind speed data into a finite set of components. Moreover, to achieve high accuracy and strong stability simultaneously, multi-objective ant lion optimization is employed to optimize the initial weights between layers and thresholds of the Elman neutral network in the optimization module, which overcomes the drawbacks of single-objective optimization algorithms. Finally, evaluation module including hypothesis testing and evaluation criteria is introduced to make a comprehensive evaluation for this system. The experimental results indicate that the average values of the mean absolute percent errors of the developed model utilizing 10-min, 30-min and 60-min interval data are 2.8220%, 5.0216% and 7.7205%, respectively, which are much lower than those of the comparison models.",

Three cases (27%) were positive for either HBV or HCV nucleic acids: HBV alone (n = 1), HCV alone (1), coinfection with HBV and HCV (1). Both HBV-positive cases were genotype A, and both HCV cases were genotype 1a. Hepatitis B and C viral copy numbers were low in all cases. Evidence for active HBV replication was found in both HBV-positive cases, as they were positive for covalently closed circular DNA. In this study, 27% of ICC cases contained HBV and/or HCV nucleic acids, suggesting an etiologic role for these viruses in some cases of IHC.",

"abstract": "Leiomyosarcoma is an extremely rare form of primary breast sarcoma. We present the pathologic and genetic findings of two cases of leiomyosarcoma of the breast. The patients were 44 and 52 years of age and they presented with circumscribed masses of 3.0 and 4.5 cm, (greatest dimension) respectively. Microscopically, the two tumors showed diffuse proliferation of spindle cells with oval and blunt-ended nuclei arranged in short fascicles or bundles. There was moderate cytologic atypia in both cases, and 6 and 12 mitotic figures per 10 high power fields, respectively. No epithelial component was identified. The tumor cells were strongly immunoreactive for markers of smooth-muscle differentiation, including desmin, muscle-specific actin, and smooth-muscle actin. Comparative genomic hybridization analysis showed losses of 10q (two of two cases), 13q (two of two cases), 17p (one of two cases), and gains of 1q (one of two cases) and 17p (one of two cases). The patterns of chromosomal imbalances identified in leiomyosarcoma of the breast are similar to those reported in leiomyosarcoma of soft tissue and uterus and are different from those reported for leiomyoma, indicating that these alterations may be important for development of malignant smooth-muscle tumors regardless of site or organ of origin.",

"abstract": "Fibronectin plays an important role in cell-to-cell adhesion, cell migration, and cell signaling. In the liver, fibronectin expression has been studied primarily as a component of the extracellular matrix, but little information is available on the expression of fibronectin protein in the neoplastic cells of hepatocellular carcinomas (HCCs). Twenty-four surgically resected HCCs were immunostained with fibronectin. Tumor and normal liver tissues were concurrently analyzed in all cases, and expression in the tumor was evaluated in comparison to the nonneoplastic liver. The average age at resection was 54 +/- 18 years for the 18 men and 6 women. Twenty-one of the cases were classic HCCs including 6 cases that were well differentiated, 12 cases moderately differentiated, and 3 cases poorly differentiated. The remaining 3 cases were moderately differentiated fibrolamellar carcinomas. In the normal liver, fibronectin labeled the sinusoids and weakly to moderately stained the cytoplasm of hepatocytes. In HCCs, 15/24 showed overexpression of fibronectin in the cytoplasm, 8/24 showed no change from the nonneoplastic liver, and one case showed decreased cytoplasmic staining. In addition, an abnormal membranous staining pattern was noted in 16/24 HCCs. In contrast to the HCCs, none of the three fibrolamellar carcinomas showed increased cytoplasmic or membranous staining. Excluding fibrolamellar carcinoma, increased cytoplasmic staining and/or an abnormal membranous staining was noted in 19/21 (90%) of HCCs. Fibronectin shows abnormal cytoplasmic and/or membranous staining in the majority of HCCs. The implications of fibronectin overexpression are uncertain but may reflect a critical step in tumor genesis.",

Patients do not have the expertise to do it. For physicians, study has shown that they usually have insufficient time to conduct the task. CliniQA tries to shift the burden of time and expertise from the decision maker to the computer system.

Besides this, the CliniQA will also return the analyzed information from the research report to help users appraise the medical evidences more efficiently.",

"abstract": "Clustering is an important task in mining evolving data streams. Beside the limited memory and one-pass con- straints, the nature of evolving data streams implies the following requirements for stream clustering: no as- sumption on the number of clusters, discovery of clus- ters with arbitrary shape and ability to handle outliers. While a lot of clustering algorithms for data streams have been proposed, they oer no solution to the combi- nation of these requirements. In this paper, we present DenStream, a new approach for discovering clusters in an evolving data stream. The \"dense\" micro-cluster (named core-micro-cluster) is introduced to summarize the clusters with arbitrary shape, while the potential core-micro-cluster and outlier micro-cluster structures are proposed to maintain and distinguish the potential clusters and outliers. A novel pruning strategy is de- signed based on these concepts, which guarantees the precision of the weights of the micro-clusters with lim- ited memory. Our performance study over a number of real and synthetic data sets demonstrates the eective- ness and eciency",

"title": "Efficient clustering of uncertain data streams",
"abstract": "Clustering uncertain data streams has recently become one of the most challenging tasks in data management because of the strict space and time requirements of processing tuples arriving at high speed and the difficulty that arises from handling uncertain data. The prior work on clustering data streams focuses on devising complicated synopsis data structures to summarize data streams into a small number of micro-clusters so that important statistics can be computed conveniently, such as Clustering Feature (CF) (Zhang et al. in Proceedings of ACM SIGMOD, pp 103---114, 1996) for deterministic data and Error-based Clustering Feature (ECF) (Aggarwal and Yu in Proceedings of ICDE, 2008) for uncertain data. However, ECF can only handle attribute-level uncertainty, while existential uncertainty, the other kind of uncertainty, has not been addressed yet. In this paper, we propose a novel data structure, Uncertain Feature (UF), to summarize data streams with both kinds of uncertainties: UF is space-efficient, has additive and subtractive properties, and can compute complicated statistics easily. Our first attempt aims at enhancing the previous streaming approaches to handle the sliding-window model by using UF instead of old synopses, inclusive of CluStream (Aggarwal et al. in Proceedings of VLDB, 2003) and UMicro (Aggarwal and Yu in Proceedings of ICDE, 2008). We show that such methods cannot achieve high efficiency. Our second attempt aims at devising a novel algorithm, cluUS , to handle the sliding-window model by using UF structure. Detailed analysis and thorough experimental reports on synthetic and real data sets confirm the advantages of our proposed method.",

"abstract": "Mining data streams poses great challenges due to the limited memory availability and real-time query response requirement. Clustering an evolving data stream is especially interesting because it captures not only the changing distribution of clusters but also the evolving behaviors of individual clusters. In this paper, we present a novel method for tracking the evolution of clusters over sliding windows. In our SWClustering algorithm, we combine the exponential histogram with the temporal cluster features, propose a novel data structure, the Exponential Histogram of Cluster Features (EHCF). The exponential histogram is used to handle the in-cluster evolution, and the temporal cluster features represent the change of the cluster distribution. Our approach has several advantages over existing methods: (1) the quality of the clusters is improved because the EHCF captures the distribution of recent records precisely; (2) compared with previous methods, the mechanism employed to adaptively maintain the in-cluster synopsis can track the cluster evolution better, while consuming much less memory; (3) the EHCF provides a flexible framework for analyzing the cluster evolution and tracking a specific cluster efficiently without interfering with other clusters, thus reducing the consumption of computing resources for data stream clustering. Both the theoretical analysis and extensive experiments show the effectiveness and efficiency of the proposed method.",

"abstract": "Governance, Risk Management and Compliance are key success factors for corporations. Every company worldwide must ensure a proper compliance level with current and future laws and regulations, but managing the dynamic nature of the regulatory environment is a challenge, for both small and medium business as well as large corporations. Specifically the challenge is knowing and interpreting which regulations impact a particular business. Governments and standard bodies keep producing new, revised legislation, and businesses today rely on employees and consultants for tracking and understanding impact on their operations. This paper introduces a novel prototype solution that addresses these concerns through the use of advanced text analytics. In particular the system is able to discover sources of regulatory content on the world wide web, track the changes to these regulations, extract metadata and semantic information and use these to provide a semantically guided comparison of regulation versions. Moreover, by leveraging the IBM DeepQA architecture, the solution is able to cross reference business objectives with the regulatory database and provide insights about the impact of new and revised laws on a company's business.",

Improving practice efficiency is a promising direction to mitigate this predicament. During the encounter, ordering lab test is one of the most frequent actions in EMR system. In this paper, our motivation is to save physician's time by providing lab test ordering list to facilitate physician practice. To this end, we developed weight based multi-label classification framework to learn to order lab test for the current encounter according to the historical EMR. Particularly, we propose to learn the physician-specific lab test ordering pattern as different physicians may have different practice behavior on the same population. Experimental results on the real data set demonstrate that physician-specific models can outperform the baseline.",

"abstract": "Clustering data streams has been attracting a lot of research efforts recently. However, this problem has not received enough consideration when the data streams are generated in a distributed fashion, whereas such a scenario is very common in real life applications. There exist constraining factors in clustering the data streams in the distributed environment: the data records generated are noisy or incomplete due to the unreliable distributed system; the system needs to on-line process a huge volume of data; the communication is potentially a bottleneck of the system. All these factors pose great challenge for clustering the distributed data streams. In this paper, we proposed an EM-based (Expectation Maximization) framework to effectively cluster the distributed data streams, with the above fundamental challenges in mind. In the presence of noisy or incomplete data records, our algorithms learn the distribution of underlying data streams by maximizing the likelihood of the data clusters. A test-and-cluster strategy is proposed to reduce the average processing cost, which is especially effective for online clustering over large data streams. Our extensive experimental studies show that the proposed algorithms can achieve a high accuracy with less communication cost, memory consumption and CPU time.",

"title": "Supporting Ontology-Based Dynamic Property and Classification in WebSphere Metadata Server",
"abstract": "Metadata management is an important aspect of today's enterprise information systems. Metadata management systems are growing from toolspecific repositories to enterprise-wide metadata repositories. In this context, one challenge is the management of the evolving metadata whose schema or meta-model itself may evolve, e.g., dynamically-added properties, which are often hard to predict upfront at the initial meta-model design time; another challenge is to organize the metadata by semantically-rich classification schemes. In this paper, we present a practical system which provides support for users to dynamically manage semantically-rich properties and classifications in the IBM WebSphere Metadata Server (MDS) by integrating an OWL ontology repository. To enable the smooth acceptance of Semantic Web technologies for developers of commercial software which must run 24 hours/day, 7 days/week, the system is designed to consist of integrated modeling paradigms, with an integrated query language and runtime repository. Specifically, we propose the modeling of dynamic properties on structured metadata as OWL properties and the modeling of classification schemes as OWL ontologies for metadata classification. We present a natural extension to OQL (Object Query Language)-like query language to embrace dynamic properties and metadata classification. We also observe that hybrid storage, i.e., horizontal tables for structured metadata and vertical triple tables for dynamic properties and classification, is suitable for the storage and query processing of co-existing structured metadata and semantic metadata. We believe that our study and experience are not specific to MDS, but are valuable for the community trying to apply Semantic Web technologies to the structured data management area.",

Challenges to solve this problem come from two aspects, (1) databases aspect. In order to fully utilize the well-developed SQL optimization engine, the generated SQL query is desired to be a single statement. (2) SPARQL query aspect. A practical SPARQL query often embeds several filters, which require comparisons between RDF results of different types. The type of RDF resources needs to be dynamically determined in the translation. In this paper, we propose an effective approach to support SPARQL queries over relational databases, with the above challenges in mind. To ensure the seamless translation, a novel facet-based scheme is designed to handle filter expressions. Optimization strategies are proposed to reduce the complexity of the generated SQL query. Experimental results confirm the effectiveness of our proposed techniques.",

"abstract": "Taking customer data as an example, the paper presents an approach to enhance the management of enterprise data by using Semantic Web technologies. Customer data is the most important kind of core business entity a company uses repeatedly across many business processes and systems, and customer data management (CDM) is becoming critical for enterprises because it keeps a single, complete and accurate record of customers across the enterprise. Existing CDM systems focus on integrating customer data from all customer-facing channels and front and back office systems through multiple interfaces, as well as publishing customer data to different applications. To make the effective use of the CDM system, this paper investigates semantic query and analysis over the integrated and centralized customer data, enabling automatic classification and relationship discovery. We have implemented these features over IBM Websphere Customer Center, and shown the prototype to our clients. We believe that our study and experiences are valuable for both Semantic Web community and data management community.",

"abstract": "With the ever-growing use of textual biomedical data, domain entity annotation has become very important in biomedicine. Previous works on annotating domain entities from biomedical references suffer from several issues, such as a data flexibility problem, language dependency, and limitations with respect to word sense disambiguation. Meanwhile, the Linked Open Data (LOD) Initiative aims at interlinking data from various open knowledge bases. The numbers of entities and properties describing semantic relationships between entities within the linked data cloud have become very large. In this paper, we propose a knowledge-incentive approach for entity annotation in biomedicine, and present Me Detect, a prototype system that we developed based on this approach. With this approach, we over-come the problems of previous works using LOD-based collective annotation. Finally, we present the results of experiments that verify the effectiveness and efficiency of our approach.",

"abstract": "Chronic disease care, e.g., care of type 2 diabetes mellitus, is a long-term, complex process involving collaboration and coordination among multiple healthcare providers. To facilitate and accelerate the process, it is key to understand the information flow and identify the information dependency (e.g., temporal dependency of co-occurrence and sequential occurrence) during care provision, which is also the objective of this work. Since most health interventions and decisions are made in outpatient encounters for chronic patients, in this paper, we propose an approach to mine temporal information dependency in outpatient encounter records using sequential pattern mining techniques. By exploring the real data of over 10,000 type 2 diabetes patients from three hospitals, the proposed approach effectively works out sets of meaningful information dependency patterns for different patient groups. The discovered information dependency can be used to guide the information sharing between different health providers, and optimize the chronic disease care coordination.",

"abstract": "In this paper, we propose a data mining method for exploring the decision-making processes of physicians from electronic patient records and test it on the medical records of patients with type-2 diabetes mellitus. This method runs in two modes: general and partitioned. In the general mode, it mines rules from the whole medical records. In the partitioned mode, with a given partition factor, medical records are assigned into categories and a corresponding set of rules will be discovered for each category. Medication prescription predictions can be provided based on these rules. By comparing mined rules and prescription prediction accuracy under different modes, we discover that: 1) both the averaged precision and recall rate of the general mode can reach around 80%; 2) physicians tend to conform to the guideline instead of having their own preferences; 3) the medication decision can be affected by some hidden factors. These findings suggest this method show promise in discovering physician practice patterns and obtaining insights from real medical records.",

A recent work on this subject was to define scheduling\n strategies on shared window joins over data streams from multiple query expressions. In these strategies, a tuple with the\n highest priority is selected to process from multiple candidates. However, the performance of these static strategies is deeply\n influenced when data are bursting, because the priority is determined only by static information, such as the query windows,\n arriving order, etc. In this paper, we propose a novel adaptive strategy where the priority of a tuple is integrated with\n realtime information.

The development of electronic health records makes it possible to automate the personalized ADE detection, i.e., to take patient clinical conditions into account during ADE detection.

The result of study indicates that therational formation pressure maintenance will decrease dramatically when the nondimensional fluid productivity index or productivityindex takes the minimum value. This method has some scientific guidance and practical value for the analysis of the waterflood technologyand production rate of low-to-moderate water development phase.",

"abstract": "Half-Heusler compounds are recognized as promising thermoelectric materials for high-temperature power generation, but their relatively high lattice thermal conductivity impedes further improvement of . Here, we report the synthesis of a new half-Heusler compound TaCoSn with a low thermal conductivity. Experimentally, the pristine TaCoSn exhibits a low lattice thermal conductivity of ~5.7 W m-1 K-1 at 300 K, which is lower than most of the other half-Heusler compounds. Phonon calculations by density functional theory indicate that the low phonon velocity, small Debye temperature, and large Grüneisen parameter are the contributors to the low thermal conductivity of TaCoSn. Importantly, intense point-defect scattering can be induced by alloying Nb at the Ta site, which further suppresses the thermal conductivity of TaCoSn. Additionally, Sb has been identified as an efficient dopant for supplying high electron concentration. Finally, the optimized n-type TaNbCoSnSb demonstrates a peak above 0.7 at 973 K. Our work demonstrates that the TaCoSn-based half-Heuslers are promising thermoelectric materials.",

We have designed and produced a nanofluid of graphene-based amphiphilic nanosheets that is very effective at low concentration. Our nanosheets spontaneously approached the oil–water interface and reduced the interfacial tension in a saline environment (4 wt % NaCl and 1 wt % CaCl2), regardless of the solid surface wettability. A climbing film appeared and grew at moderate hydrodynamic condition to encapsulate the oil phase. With strong hydrodynamic power input, a solid-like interfacial film formed and was able to return to its original form even after being seriously disturbed. The film rapidly separated oil and water phases for slug-like oil displacement. The unique behavior of our nanosheet nanofluid tripled the best performance of conventional nanofluid flooding methods under similar conditions.",

In this paper, we studied the thermoelectric properties of p-type lithium (Li)-doped Mg3Sb2 prepared by ball milling and hot pressing. A maximum ZT value ~ 0.6 at about 773 K was achieved in Mg2.975Li0.025Sb2, which was ascribed to the increased carrier concentration by Li doping. Mixed scattering mechanism is dominated at lower temperature, yielding higher carrier mobility. Isoelectronic substitution of Zn on the Mg site further increased the electrical conductivity by narrowing the band gap and decreased the lattice thermal conductivity by double substitution, contributing to an enhanced average ZT in Mg2.475Zn0.5Li0.025Sb2.",

"title": "Deep defect level engineering: A strategy of optimizing the carrier concentration for high thermoelectric performance",
"abstract": "Thermoelectric properties are heavily dependent on the carrier concentration, and therefore the optimization of carrier concentration plays a central role in achieving high thermoelectric performance. The optimized carrier concentration is highly temperature-dependent and could even possibly vary within one order of magnitude in the temperature range of several hundreds of Kelvin. Practically, however, the traditional doping strategy will only lead to a constant carrier concentration, and thus the thermoelectric performance is only optimized within a limited temperature range. Here, we demonstrate that a temperature-dependent carrier concentration can be realized by simultaneously introducing shallow and deep defect levels. In this work, iodine (I) and indium (In) are co-doped in PbTe, where iodine acts as the shallow donor level that supplies sufficient electrons and indium builds up the localized half-filled deep defect state in the band gap. The indium deep defect state traps electrons at a lower temperature and the trapped electrons will be thermally activated back to the conduction band when the temperature rises. In this way, the carrier concentration can be engineered as temperature-dependent, which matches the theoretically predicted optimized carrier concentration over the whole temperature range. As a result, a room temperature ZT of similar to 0.4 and a peak ZT of similar to 1.4 at 773 K were obtained in the n-type In/I co-doped PbTe, leading to a record-high average ZT of similar to 1.04 in the temperature range of 300 to 773 K. Importantly, since deep defect levels also exist in other materials, the strategy of deep defect level engineering should be widely applicable to a variety of materials for enhancing the thermoelectric performance across a broad temperature range.",

"abstract": "Single crystal tin selenide (SnSe) has attracted much attention for its excellent thermoelectric performance. However, polycrystalline SnSe exhibits unsatisfactory figure-of-merit due to the inferior electrical properties, especially for n-type SnSe. In this work, a high concentration of Br doping (6-12 atm%) on the Se site effectively increases the Hall carrier concentration from 1.6 x 10(17) cm(-3) (p-type) in undoped SnSe to 1.3 x 10(19) cm(-3) (n-type) in Br-doped SnSe0.88Br0.12, leading to an increased electrical conductivity close to that of a single crystal. Combined with the decreased lattice thermal conductivity due to the enhanced phonon scattering by composition fluctuation and dislocations, a peak ZT of approximate to 1.3 at 773 K, together with the enhanced average ZT is obtained in SnSe0.9Br0.1 along the hot pressing direction.",

"abstract": "Group IIIA elements (B, Ga, In, and Tl) have been doped into PbSe for enhancement of thermoelectric properties. The electrical conductivity, Seebeck coefficient, and thermal conductivity were systematically studied. Room-temperature Hall measurements showed an effective increase in the electron concentration upon both Ga and In doping and the hole concentration upon Tl doping to similar to 7 x 10(19) cm(-3). No resonant doping phenomenon was observed when PbSe was doped with B, Ga, or In. The highest room-temperature power factor x 10(-3)W m(-1) K-2 was obtained for PbSe doped with 2 atom % B. However, the power factor in B-doped samples decreased with increasing temperature, opposite to the trend for the other dopants. A figure of merit (ZT) of similar to 1.2 at similar to 873 K was achieved in PbSe doped with 0.5 atom % Ga or In. With Tl doping, modification of the band structure around the Fermi level helped to increase the Seebeck coefficient, and the lattice thermal conductivity decreased, probably as a result of effective phonon scattering by both the heavy Tl3+ ions and the increased grain boundary density after ball milling. The highest p-type ZT value was similar to 1.0 at similar to 723 K.",

Even though the ZT is high in single crystal SnSe, it was very low in its polycrystalline form due to the very low electrical conductivity (<10(3) S m(-1)) from 300 K to 700 K. In this work, we report studies on enhancement of electrical conductivity by Na doping to optimize the carrier concentration in polycrystalline SnSe prepared by melting and hot pressing. A room temperature carrier concentration of similar to 2.7 x 10(19) cm(-3) was obtained in 2 atm% Na-doped SnSe samples with the highest power factor obtained in 1.5 atm% Na-doping.

"abstract": "Lead telluride and its alloys have been extensively studied for medium temperature thermoelectric applications due to decent figure-of-merit (ZT) at temperature close to 900K. However, little emphasis has been given to improve the ZT near room temperature. In this investigation, we report a systematic study of Cr doping in PbTe1−ySey with y=0, 0.25, 0.5, 0.75, 0.85, and 1. We found the peak ZT temperature increased with increasing concentration of Se. The highest ZT of ~0.6 at room temperature in Te-rich Cr0.015Pb0.985Te0.75Se0.25 was obtained due to a lowered thermal conductivity and enhanced power factor resulted from high Seebeck coefficient of about −220µVK−1 and high Hall mobility ~1120cm2V−1s−1 at room temperature. A room temperature ZT of ~0.5 and peak ZT of ~1 at about 573–673K is shown by Se-rich sample Cr0.01Pb0.99Te0.25Se0.75. This improvement of the room temperature ZT improved the average ZT over a wide temperature range and could potentially lead to a single leg efficiency of thermoelectric conversion for Te-rich Cr0.015Pb0.985Te0.75Se0.25 up to ~11% and Se-rich Cr0.01Pb0.99Te0.25Se0.75 up to ~13% with cold side and hot side temperature at 300K and 873K, respectively, if matched with appropriate p-type legs.",

High metal volume fraction cermet 1 and low metal volume fraction cermet 2 were deposited with O2 partial pressure of 0.15 mTorr and 0.25 mTorr, respectively, with direct current power density of 6.58 W cm−2. The complex refractive indices from ellipsometry were used to design solar selective absorber. The reflectance, thermal stability, and morphology were studied in absorbers on Cu and stainless steel. The effect of TiO2 and SiO2 as anti-reflective coating layers was investigated. The absorber on Cu substrate has high absorptance of 90.8% and low emittance of 4.9% (100 °C), and changed to 96.0% and 6.6%, respectively, after annealing at 300 °C for 4 days.",

"abstract": "1-2-2-type Zintl phase compound has aroused great interest for potential thermoelectric applications. However, YbMg2Sb2 is seldom studied due to the very low electrical conductivity resulting from the large difference in the electronegativity between Mg and Sb. In this paper, we adjust the covalently bonded network of MgSb by replacing part of the Mg with Zn which has the electronegativity closer to that of Sb. The decreased polarity in the anionic framework offers more free distance for electrons for the enhanced Hall mobility and electrical conductivity. Together with the increased point defect and the decreased lattice thermal conductivity by introduction of Zn, the maximum ZT value of ∼0.8 at 773 K is achieved in YbMg0.9Zn1.1Sb2 which is ∼100% enhancement compared with that of YbMg2Sb2.",

A promising Zintl-phase thermoelectric material, 2-1-2-type Eu2ZnSb2 (P6(3)/mmc), was prepared and investigated. The extremely low lattice thermal conductivity is attributed to the external Eu atomic layers inserted in the [Zn2Sb2](2-) network in the structure of 1-2-2-type EuZn2Sb2 (P (3) over bar m1), as well as the abundant inversion domain boundary. By regulating the Zn deficiency, the electrical properties are significantly enhanced, and the maximum ZT value reaches similar to 1.0 at 823 K for Eu2Zn0.98Sb2.

"abstract": "We present detailed studies of potassium doping in PbTe1-ySey (y = 0, 0.15, 0.25, 0.75, 0.85, 0.95, and 1). It was found that Se increases the doping concentration of K in PbTe as a result of the balance of electronegativity and also lowers the lattice thermal conductivity because of the increased number of point defects. Tuning the composition and carrier concentration to increase the density of states around the Fermi level results in higher Seebeck coefficients for the two valence bands of PbTe1-ySey. Peak thermoelectric figure of merit (ZT) values of similar to 1.6 and similar to 1.7 were obtained for Te-rich K0.02Pb0.98Te0.75Se0.25 us at 773 K and Se-rich K0.02Pb0.98Te0.15Se0.85 at 873 K, respectively. However, the average ZT was higher in Te-rich compositions than in Se-rich compositions, with the best found in K0.02Pb0.98Te0.75Se0.25. Such a result is due to the improved electron transport afforded by heavy K doping with the assistance of Se.",

"abstract": "Solar energy is abundant and environmentally friendly. Light trapping in solar-energy-harvesting devices or structures is of critical importance. This article reviews light trapping with metallic nanostructures for thin film solar cells and selective solar absorbers. The metallic nanostructures can either be used in reducing material thickness and device cost or in improving light absorbance and thereby improving conversion efficiency. The metallic nanostructures can contribute to light trapping by scattering and increasing the path length of light, by generating strong electromagnetic field in the active layer, or by multiple reflections/absorptions. We have also discussed the adverse effect of metallic nanostructures and how to solve these problems and take full advantage of the light-trapping effect.",

"abstract": "Zintl compounds have caught great attention in thermoelectric applications due to their intrinsic “electron-crystal, phonon-glass” structures. Previous studies suggested that Zintl-phase Eu2ZnSb2 was a promising thermoelectric material due to its ultralow thermal conductivity. In this work, we used Ag to regulate the Zn–Sb framework for enhanced electrical properties, and prepared Eu2Zn1-0.5xAgxSb2 (x = 0.02, 0.06, and 0.1) by ball milling and spark plasma sintering. The additional Ag fills the initial vacancies and causes both increased carrier concentration and mobility. The maximum ZT reaches ~0.92 at 823 K for Eu2Zn0.97Ag0.06Sb2. By further reducing the Zn content, the carrier concentration increases close to the optimum value, and a peak ZT value of ~1.1 at 823 K was achieved for Eu2Zn0.95Ag0.06Sb2.",

The as-synthesized Pb(1-x)Bi(x)Te (x = 0.005, 0.010, 0.015, 0.020) nanocrystals are characterized by X-ray diffraction, X-ray photoelectron spectroscopy and Hall measurements. The nanocrystals with controlled spherical, cuboctahedral, and cubic shapes were readily prepared by varying the Bi doping concentration. Thermoelectric investigation of these nanocrystals shows that the Bi(3+) doping increases electrical conductivity from 350 to 650 K and changes the Seebeck coefficient sign from positive to negative.",

"abstract": "We present detailed studies of potassium doping in PbTe1-ySey (y = 0, 0.15, 0.25, 0.75, 0.85, 0.95, and 1). It was found that Se increases the doping concentration of K in PbTe as a result of the balance of electronegativity and also lowers the lattice thermal conductivity because of the increased number of point defects. Tuning the composition and carrier concentration to increase the density of states around the Fermi level results in higher Seebeck coefficients for the two valence bands of PbTe1-ySey. Peak thermoelectric figure of merit (ZT) values of similar to 1.6 and similar to 1.7 were obtained for Te-rich K0.02Pb0.98Te0.75Se0.25 us at 773 K and Se-rich K0.02Pb0.98Te0.15Se0.85 at 873 K, respectively. However, the average ZT was higher in Te-rich compositions than in Se-rich compositions, with the best found in K0.02Pb0.98Te0.75Se0.25. Such a result is due to the improved electron transport afforded by heavy K doping with the assistance of Se.",

"abstract": "Ti, V, Cr, Nb, and Mo are found to be effective at increasing the Seebeck coefficient and power factor of n-type PbSe at temperatures below 600 K. It is found that the higher Seebeck coefficients and power factors are due to higher Hall mobility approximate to 1000 cm(2) V-1 s(-1) at lower carrier concentration. A larger average ZT value (relevant for applications) can be obtained by an optimization of carrier concentration to approximate to 10(18)-10(19) cm(-3). Even though the highest room temperature power factor approximate to 3.3 x 10(-3) W m(-1) K-2 is found in 1 at% Mo-doped PbSe, the highest ZT is achieved in Cr-doped PbSe. Combined with the lower thermal conductivity, ZT is improved to approximate to 0.4 at room temperature and peak ZTs of approximate to 1.0 are observed at approximate to 573 K for Pb0.9925Cr0.0075Se and approximate to 673 K for Pb0.995Cr0.005Se. The calculated device efficiency of Pb0.995Cr0.005Se is as high as approximate to 12.5% with cold side 300 K and hot side 873 K, higher than those of all the n-type PbSe materials reported in the literature.",

"abstract": "Spectrally-selective solar absorbers are widely used in solar hot water and concentrating solar power (CSP) systems. However, their performance at high temperatures (>450 degrees C) is still not satisfactory due to high infrared (IR) emittance and lack of long-term thermal stability. Here, we explore yttria-stabilized zirconia (YSZ) cermet-based spectrally-selective surfaces for high-temperature solar absorber applications. The developed multilayer selective surface comprises two sunlight-absorbing W-Ni-YSZ cermet layers with different W-Ni volume fractions inside the YSZ matrix, two anti-reflection coatings (ARCs), and one tungsten IR reflection layer for reduced IR emittance and improved thermal stability, deposited on a polished stainless steel (SS) substrate. The fabricated solar absorbers are tested for their long-term thermal stability at 600 degrees C. We find a distinct change in the surface morphology of the solar absorbers when oxygen is highly deficient in the YSZ-ARC layers. The oxygen deficiency can be effectively overcome through increasing the oxygen partial pressure during sputtering, which leads to a stable solar absorber with a solar absorptance of similar to 0.91 and a total hemispherical emittance of similar to 0.13 at 500 degrees C. Those values are obtained at the actual operating temperature using an absolute and direct method that measures the total hemispherical emittance with high accuracy. In contrast, most reports on solar absorber development in the literature to date use only near room-temperature spectroscopy techniques that have been shown to significantly underestimate the total hemispherical emittance. This makes our experimentally demonstrated total hemispherical emittance value the lowest ever reported for a high-temperature stable solar absorber with solar absorptance above 0.9.",

"abstract": "Realization of ambipolar doping (n- and p-type) in thermoelectric materials is highly critical for module design. However, many thermoelectric materials can only be doped into one type, due to the Fermi-level pinning by intrinsic defects, or have poor performance for one doping type. AgBiSe2 is a typical case that shows persistent n-type doping while p-type AgBiSe2 has been predicted to exhibit higher thermoelectric performance but has not been reliably obtained nor has the performance been demonstrated. Here, we demonstrate the successful experimental synthesis of p-type AgBiSe2 by suppressing Se vacancies via adding an excess amount of Se. In addition, we show that Pb doping at the Bi site can effectively increase the hole concentration and optimize the power factor of p-type AgBiSe2. This leads to promising thermoelectric performance close to room temperature. Our work demonstrates the importance of defect engineering for overcoming the doping bottleneck, thus promoting the discovery of new thermoelectric materials.",

"abstract": "Solar thermal technologies such as solar hot water and concentrated solar power trough systems rely on spectrally selective solar absorbers. These solar absorbers are designed to efficiently absorb the sunlight while suppressing re-emission of infrared radiation at elevated temperatures. Efforts for the development of such solar absorbers must not only be devoted to their spectral selectivity but also to their thermal stability for high temperature applications. Here, selective solar absorbers based on two cermet layers are fabricated on mechanically polished stainless steel substrates using a magnetron sputtering technique. The targeted operating temperature is 500-600 degrees C. A detrimental change in the morphology, phase, and optical properties is observed if the cermet layers are deposited on a stainless steel substrate with a thin nickel adhesion layer, which is due to the diffusion of iron atoms from the stainless steel into the cermet layer forming a FeWO4 phase. In order to improve thermal stability and reduce the infrared emittance, tungsten is found to be a good candidate for the infrared reflector layer due to its excellent thermal stability and low infrared emittance. A stable solar absorptance of approximate to 0.90 is demonstrated, with a total hemispherical emittance of 0.15 at 500 degrees C.",

"abstract": "Controlling solar spectra via the careful design could realize the optimized utilization of energy. Especially for spectrally selective solar absorbers, achieving the appropriate transition wavelength can boom conversion efficiency for a certain application under the consideration of cost. Here, we experimentally demonstrated a kind of WTa-SiO2 cermet based absorbers with transition wavelength of around 1500 nm, 2000 nm, and 2500 nm, which can meet the versatile applications under the conditions of different operating temperatures and different optical concentrations. All the absorbers possess a promising solar absorptance of above 95% and photothermal efficiency of above 91% at 82 degrees C with 1 sun, as well as the superior thermal stability at 600 degrees C due to the formation of tantalum oxide in WTa-SiO2 cermet in the annealing process.",

"abstract": "Iodine-doped n-type SnSe polycrystalline by melting and hot pressing is prepared. The prepared material is anisotropic with a peak ZT of approximate to 0.8 at about 773 K measured along the hot pressing direction. This is the first report on thermoelectric properties of n-type Sn chalcogenide alloys. With increasing content of iodine, the carrier concentration changed from 2.3 x 10(17) cm(-3) (p-type) to 5.0 x 10(15) cm(-3) (n-type) then to 2.0 x 10(17) cm(-3) (n-type). The decent ZT is mainly attributed to the intrinsically low thermal conductivity due to the high anharmonicity of the chemical bonds like those in p-type SnSe. By alloying with 10 at% SnS, even lower thermal conductivity and an enhanced Seebeck coefficient were achieved, leading to an increased ZT of approximate to 1.0 at about 773 K measured also along the hot pressing direction.",

"abstract": "Agenesis of the dorsal pancreas (ADP) is a very rare disease with no specific symptoms, and the pathogenesis is not clear. Some patients will be accompanied by other diseases, such as pancreatic tumor or pancreatitis. But most cases are very atypical and difficult to distinguish. Some syndromes of pancreatic exocrine insufficiency are common in patients with ADP. Here, we report two cases of ADP and summarize the clinical features, diagnosis, and treatment of ADP. Case A is a 65-year-old Chinese woman who presented with abdominal pain accompanied by nausea, bloating and acid reflux. The enhanced abdominal CT scan found nothing meaningful except the absence of the body and tail of the pancreas. The diagnosis was considered as gastrointestinal dysfunction cause by exocrine pancreatic insufficiency and recovered after symptomatic treatment. Case B is a 61-year-old Chinese woman who presented with abdominal pain accompanied by fever, vomiting and bloating. The abdominal CT showed multiple stones in the gallbladder, and the body and tail of the patient’s pancreas were absent. She was diagnosed with cholelithiasis and recovered after laparoscopic cholecystectomy. Agenesis of the dorsal pancreas (ADP) is a rare congenital disease with an unclear pathogenesis that presents multiple symptoms. It should be considered when the patients have non-specific, persistent and unexplained symptoms such as bloating or uncontrolled blood sugar. Imaging examination is helpful for diagnosis. And it does not require surgical intervention unless it accompanies other diseases, EPI need to be considered when the non-specific gastrointestinal symptoms appear.",

"title": "Nonoperative management for perforated peptic ulcer: who can benefit?",
"abstract": "Although nonoperative management for perforated peptic ulcer (PPU) has been used for several decades, the indication is still unclear. A clinicoradiological score was sought to predict who can benefit from it.A clinicoradiological protocol for the assessment of patients presenting with PPU was used. A logistic regression model was applied to identify determinant variables and construct a clinical score that would identify patients who can be successfully treated with nonoperative management.Of 241 consecutive patients with PPU, 107 successfully received nonoperative management, and 134 required surgery. In multivariable analysis, the following four variables correlated with surgery and were given one point each toward the clinical score: age ≥70 years, fluid collection detection by ultrasound, contrast extravasation detection by water-soluble contrast examination, and Acute Physiology and Chronic Health Evaluation II (APACHE II) score ≥8. Eighty-five percent of patients with a score of 1 or less were successfully treated with nonoperative management, whereas 23 of 29 patients with a score of 3 or more required surgery. The area under the receiver operating characteristic curve was 0.804 (95% confidence interval = 0.717-0.891).By combining clinical, radiological parameters, and APACHE II score, the clinical score allowed early identification of PPU patients who can benefit from nonoperative management.",

"title": "Infection recurrence following minimally invasive treatment in patients with infectious pancreatic necrosis.",
"abstract": "BACKGROUND In recent decades, an increasing number of patients have received minimally invasive intervention for infected pancreatic necrosis (IPN) because of the benefits in reducing postoperative multiple organ failure and mortality. However, there are limited published data regarding infection recurrence after treatment of this patient population. AIM To investigate the incidence and prediction of infection recurrence following successful minimally invasive treatment in IPN patients. METHODS Medical records for 193 IPN patients, who underwent minimally invasive treatment between February 2014 and October 2018, were retrospectively reviewed. Patients, who survived after the treatment, were divided into two groups: one group with infection after drainage catheter removal and another group without infection. The morphological and clinical data were compared between the two groups. Significantly different variables were introduced into the correlation and multivariate logistic analysis to identify independent predictors for infection recurrence. Sensitivity and specificity for diagnostic performance were determined. RESULTS Of the 193 IPN patients, 178 were recruited into the study. Of them, 9 (5.06%) patients died and 169 patients survived but infection recurred in 13 of 178 patients (7.30%) at 7 (4-10) d after drainage catheters were removed. White blood cell (WBC) count, serum C-reactive protein (CRP), interleukin-6, and procalcitonin levels measured at the time of catheter removal were significantly higher in patients with infection than in those without (allP< 0.05). In addition, drainage duration and length of the catheter measured by computerized tomography scan were significantly longer in patients with infection (P= 0.025 andP< 0.0001, respectively). Although these parameters all correlated positively with the incidence of infection (allP< 0.05), only WBC, CRP, procalcitonin levels, and catheter length were identified as independent predictors for infection recurrence. The sensitivity and specificity for infection prediction were high in WBC count (>= 9.95 x 10(9)/L) and serum procalcitonin level (>= 0.05 ng/mL) but moderate in serum CRP level (cut-off point >= 7.37 mg/L). The catheter length (cut-off value >= 8.05 cm) had a high sensitivity but low specificity to predict the infection recurrence. CONCLUSION WBC count, serum procalcitonin, and CRP levels may be valuable for predicting infection recurrence following minimally invasive intervention in IPN patients. These biomarkers should be considered before removing the drainage catheters.",

"abstract": "Background. Increasing research attention has focused on tumor-infiltrating immune cells. However, the threshold of an immune score for use in predicting overall survival (OS) and disease-free survival (DFS) in hepatocellular carcinoma (HCC) is not defined. This study aims at exploring the association between immune scores with prognosis and building a clinical nomogram for predicting the survival of HCC patients.Material and Methods. A total of 299 patients were enrolled in this study. Their clinical pathological characteristics and immune scores downloaded from The Cancer Genome Atlas (TCGA) database were analyzed. Survival differences between different immune score subgroups were compared, and a final nomogram was built using the Cox proportional hazards regression model. The predictive performance of the nomogram was assessed using the concordance index (C-index) and a calibration plot.Results. All the patients were divided into three subgroups based on immune scores. Patients with medium and high immune scores had significantly better OS (HR and 95% CI: 0.417 [0.186-0.937] and 0.299 [0.146-0.616]) and DFS (HR and 95% CI: 0.575 [0.329-1.004] and 0.451 [0.278-0.733], respectively, compared with those with low immune scores. The C indices for OS and DFS were 0.748 (95% CI, 0.687-0.809) and 0.675 (95% CI, 0.630-0.720), respectively. A calibration plot used to determine the probability of survival at 3 or 5 years (OS and DFS) showed a significant agreement between nomogram predictions and actual observations.Conclusions. Medium and high immune scores are significantly associated with prolonged OS and DFS in HCC patients. Nomograms built in this study can help doctors and patients assess prognosis and guide treatment.",

"abstract": "Background. Severe acute pancreatitis (SAP) is a deadly condition, with a mortality rate ranging from 15% to 30%. Recently, blood purification therapy has been adopted in administrating SAP patients. The present study aimed at evaluating the effect of continuous hemofiltration therapy for SAP. Methods. A systematic search of Cochrane Library, PubMed, and Embase was carried out until October 1st, 2019. Prospective studies comparing outcomes for SAP patients between continuous hemofiltration and standard therapy were enrolled. Results. Continuous hemofiltration therapy was associated with lower level of PACHE II score (MD = -1.49; 95% CI: -2.69 to -0.29, P = 0.02), CRP (MD = -1.56 mg/L; 95% CI: -2.64 to -0.47, P = 0.005), Cr (MD = -3.57 umol/L; 95% CI: -5.50 to -1.65, P = 0.003), and Bun (MD = -3.63 mmol/L; 95% CI: -6.07 to -1.20, P = 0.003) at 72 h after onset of treatment. Continuous hemofiltration therapy was associated with shorter length of abdominal pain relief time (MD = -1.82 hours; 95% CI: -2.93 to -0.71, P = 0.001), lower surgery rate (OR = 0.15; 95% CI: 0.03 to 0.78, P = 0.02), and mortality rate (OR = 0.54; 95% CI: 0.37 to 0.77, P = 0.0007). Conclusions. continuous hemofiltration therapy could effectively alleviate SAP as early as 72 hours after onset of treatment, lowering the level of Bun, Cr, CRP, and APACHE II scores. Continuous hemofiltration therapy could confer SAP patients with lower mortality rates.",

Methods: The medical records of 193 patients with pyogenic liver abscess were analysed retrospectively. The patitents were divided into two groups (percutaneously group and surgical group)according to the different treatment method. The length of hospital stay, pro-cedure-related complications, the rate of treatment success and death were compared between the groups. Results: Ninty-six patients were treated percutaneously, either by needle aspiration or catheter drainage and 97 patients were treated surgically. There was no statistically significant difference in patients' demographics or abscess characteristics between groups. The success rate, mortality and length of hospital stay in percutaneous and surgical group was 87.5% vs 94.8%,2.1% vs 2.1% and(20.8±12.4)d vs(18.9±13.5)d, respectively with no significantly difference (P>0.05). There was statistically significant difference in morbidity rate between the groups (2.1% vs 9.3%, P=0.037). Conclusions: Percutaneous and surgical treatment of pyogenic liver abscesses are both effective, nevertheless percutaneous drainage carries lower morbidity and should be the first-line treatment.",

"title": "Timing, distribution, and microbiology of infectious complications after necrotizing pancreatitis.",
"abstract": "BACKGROUND Acute pancreatitis (AP) is a common acute abdominal disease worldwide, and its incidence rate has increased annually. Approximately 20% of AP patients develop into necrotizing pancreatitis (NP), and 40% to 70% of NP patients have infectious complications, which usually indicate a worse prognosis. Infection is an important sign of complications in NP patients. AIM To investigate the difference in infection time, infection site, and infectious strain in NP patients with infectious complications. METHODS The clinical data of AP patients visiting the Department of General Surgery of Xuanwu Hospital of Capital Medical University from January 1, 2014 to December 31, 2018 were collected retrospectively. Enhanced computerized tomography or magnetic resonance imaging findings in patients with NP were included in the study. Statistical analysis of infectious bacteria, infection site, and infection time in NP patients with infectious complications was performed, because knowledge about pathogens and their antibiotic susceptibility patterns is essential for selecting an appropriate antibiotic. In addition, the factors that might influence the prognosis of patients were analyzed. RESULTS In this study, 539 strains of pathogenic bacteria were isolated from 162 patients with NP infection, including 212 strains from pancreatic infections and 327 strains from extrapancreatic infections. Gram-negative bacteria were the main infectious species, the most common of which were Escherichia coli and Pseudomonas aeruginosa. The extrapancreatic infection time (9.1 +/- 8.8 d) was earlier than the pancreatic infection time (13.9 +/- 12.3 d). Among NP patients with early extrapancreatic infection (< 14 d), bacteremia (25.12%) and respiratory tract infection (21.26%) were predominant. Among NP patients with late extrapancreatic infection (> 14 d), bacteremia (15.94%), respiratory tract infection (7.74%), and urinary tract infection (7.71%) were predominant. Drug sensitivity analysis showed that P. aeruginosa was sensitive to enzymatic penicillins, third- and fourth-generation cephalosporins, and carbapenems. Acinetobacter baumannii and Klebsiella pneumoniae were sensitive only to tigecycline; Staphylococcus epidermidis and Enterococcus faecium were highly sensitive to linezolid, tigecycline, and vancomycin. CONCLUSION In this study, we identified the timing, the common species, and site of infection in patients with NP.",

"abstract": "The role of pancreatic stellate cells (PSCs) has been established in many studies. However, the potential mechanism for the chemoresistance induced by PSCs has not been fully elucidated. In the present study, human pancreatic cancer cell lines were directly or indirectly co-cultured with PSCs. The inhibition rate and IC50 values were assessed to determine the ability of chemoresistance. RT-PCR and western blot analysis were used to evaluate Hes 1 and Jagged 1 expression before and after co-culture with PSCs. To determine the relationship between Hes 1 expression and survival in pancreatic cancer patients, Kaplan-Meier survival analysis was performed. PSCs promoted the expression of Hes 1 in both PANC-1 and BxPC-3 cell lines and induced chemoresistance to gemcitabine. A Notch signaling pathway inhibitor (L1790) and Hes 1 siRNA reversed the chemoresistance induced by PSCs. In 72 resected pancreatic cancer patients, high Hes 1 expression was observed in 34 patients with shorter overall and progression-free survival times. In conclusion, Hes 1 is essential for chemoresistance induced by PSCs and is associated with poor prognosis in pancreatic cancer patients. Therapy targeting the Notch signaling pathway may reverse chemoresistance and improve survival in patients with pancreatic cancer.",

"abstract": "Although peritoneal cytology has been used to determine pancreatic cancer staging for more than three decades, its prognostic significance in potentially resectable pancreatic cancer is inconclusive. We therefore conducted this meta-analysis to investigate the impact of peritoneal cytology status on the clinicopathological features and survival outcomes in potentially resectable pancreatic cancer. Ten studies were identified for this meta-analysis after searching the PubMed, Web of Science and China National Knowledge Infrastructure (CNKI) electronic databases. Our results showed that positive peritoneal cytology was associated with tumor size (OR 11.65, P = 0.001), tumor location (OR 0.37, P = 0.000), serosal invasion (OR 3.89, P = 0.000), portal vein invasion (OR 1.82, P = 0.016), lymph vessel invasion (OR 2.71, P = 0.026), T stage (OR 2.65, P = 0.037) and N stage (OR 2.34, P = 0.001) in resectable pancreatic cancer. Patients with positive peritoneal cytology demonstrated poor overall survival (OS; HR 3.18, P = 0.000) and disease-free survival (DFS; HR 2.88, P = 0.000) times. Based on our meta-analysis, we conclude that positive peritoneal cytology is an indicator of advanced stage pancreatic cancer with a poor prognosis; hence, radical resection should not be performed on these patients.",

"abstract": "Purpose The incidence of pancreatic neuroendocrine tumors (pNETs) has continued to increase, but for pNETs, there is still no distinction between treatments based on anatomical location. We aim to determine whether NETs located at the head and body/tail of the pancreas are different. Patients and methods Within the Surveillance, Epidemiology, and End Results database (2004-2016), we focused on pNETs patients with comprehensive information. The patients were divided into two groups based on tumors' location. We compared the characteristics of the two groups and assessed the risk factors for lymphatic metastasis. Survival analysis was performed based on the biological characteristics of the tumor. Results In all 3011 patients, pNETs were more common in the body/tail (62.94%) than in the head (37.06%) of the pancreas. The risk factors for lymph node metastasis in the two groups were different. Nonmetastatic, low-grade pancreatic body/tail NETs had the best prognosis (p < 0.001). For low-grade tumors (G1-G2), lymphatic metastasis did not significantly affect the prognosis of patients with pancreatic head NETs (p = 0.098) but affected the overall survival of patients with pancreatic body/tail NETs (p < 0.001). The tumors at the pancreatic head were larger (p = 0.001), more likely to have positive lymph nodes (p < 0.001) and more prone to locally advanced and distant invasion (p < 0.001). The prognosis of pancreatic head NETs 21-40 mm was worse than that of body/tail pNETs (p < 0.001). For non-functional NETs, the overall survival of pancreatic body/tail tumors was better (p < 0.001). Conclusion The pancreatic head and pancreatic body/tail NETs have different biological characteristics and clinical outcomes and they should be treated differently.",

"abstract": "Bone marrow-derived mesenchymal stem cells (BM-MSCs) have been demonstrated as an ideal autologous stem cells source for cell-based therapy for myocardial infarction (MI). However, poor viability of donor stem cells after transplantation limits their therapeutic efficiency, whereas the underlying mechanism is still poorly understood. Autophagy, a highly conserved process of cellular degradation, is required for maintaining homeostasis and normal function. Here, we investigated the potential role of autophagy on apoptosis in BM-MSCs induced by hypoxic injury. BM-MSCs, isolated from male C57BL/6 mice, were subjected to hypoxia and serum deprivation (H/SD) injury for 6, 12, and 24 h, respectively. The autophagy state was regulated by 3-methyladenine (3MA) and rapamycin administration. Furthermore, compound C was administrated to inhibit AMPK. The apoptosis induced by H/SD was determined by TUNEL assays. Meanwhile, autophagy was measured by GFP-LC3 plasmids transfection and transmission electron microscope. Moreover, protein expressions were evaluated by Western blot assay. In the present study, we found that hypoxic stress increased autophagy and apoptosis in BM-MSCs time dependently. Meanwhile, hypoxia increased the activity of AMPK/mTOR signal pathway. Moreover, increased apoptosis in BM-MSCs under hypoxia was abolished by 3-MA, whereas was aggravated by rapamycin. Furthermore, the increased autophagy and apoptosis in BM-MSCs induced by hypoxia were abolished by AMPK inhibitor compound C. These data provide evidence that hypoxia induced AMPK/mTOR signal pathway activation which regulated the apoptosis and autophagy in BM-MSCs. Furthermore, the apoptosis of BM-MSCs under hypoxic condition was regulated by autophagy via AMPK/mTOR pathway.",

"title": "[Exploration of omics mechanism and drug prediction of coronavirus-induced heart failure based on clinical bioinformatics].",
"abstract": " Present study investigated the mechanism of heart failure associated with coronavirus infection and predicted potential effective therapeutic drugs against heart failure associated with coronavirus infection. Coronavirus and heart failure were searched in the Gene Expression Omnibus (GEO) and omics data were selected to meet experimental requirements. Differentially expressed genes were analyzed using the Limma package in R language to screen for differentially expressed genes. The two sets of differential genes were introduced into the R language cluster Profiler package for gene ontology (GO) and Kyoto gene and genome encyclopedia (KEGG) pathway enrichment analysis. Two sets of intersections were taken. A protein interaction network was constructed for all differentially expressed genes using STRING database and core genes were screened. Finally, the apparently accurate treatment prediction platform (EpiMed) independently developed by the team was used to predict the therapeutic drug. The GSE59185 coronavirus data set was searched and screened in the GEO database, and divided into wt group, ΔE group, Δ3 group, Δ5 group according to different subtypes, and compared with control group. After the difference analysis, 191 up-regulated genes and 18 down-regulated genes were defined. The GEO126062 heart failure data set was retrieved and screened from the GEO database. A total of 495 differentially expressed genes were screened, of which 165 were up-regulated and 330 were down-regulated. Correlation analysis of differentially expressed genes between coronavirus and heart failure was performed. After cross processing, there were 20 GO entries, which were mainly enriched in virus response, virus defense response, type Ⅰ interferon response, γ interferon regulation, innate immune response regulation, negative regulation of virus life cycle, replication regulation of viral genome, etc . There are 5 KEGG pathways, mainly interacting with tumor necrosis factor signaling pathway, IL-17 signaling pathway, cytokine and receptor interaction, Toll-like receptor signaling pathway, human giant cells viral infection related. All differentially expressed genes were introduced into the SREING online analysis website for protein interaction network analysis, and core genes such as signal transducer and activator of transcription 3, IL-10, IL17, TNF, interferon regulatory factor 9, 2'-5'-oligoadenylate synthetase 1, mitogen-activated protein kinase 3, radical s-adenosyl methionine domain containing 2, c-x-c motif chemokine ligand 10, caspase 3 and other genes were screened. The drugs predicted by EpiMed's apparent precision treatment prediction platform for disease-drug association analysis are mainly TNF-α inhibitors, resveratrol, ritonavir, paeony, retinoic acid, forsythia, and houttuynia cordata. The abnormal activation of multiple inflammatory pathways may be the cause of heart failure in patients after coronavirus infection. Resveratrol, ritonavir, retinoic acid, amaranth, forsythia, houttuynia may have therapeutic effects. Future basic and clinical research is warranted to validate present results and hypothesis.",

"abstract": "Coronary heart disease is a prevalent and fatal killer caused by vulnerable atherosclerotic plaques (VASPs). However, the precise detection and treatment of VASPs remains a difficult challenge. Here, we present the development of noninvasive human serum albumin (HSA)-based theranostic nanomedicines (NMs) for the specific diagnosis and effective therapy of VASPs. Methods: The ICG/SRT@HSA-pept NMs were formulated to contain payloads of the near-infrared (NIR) fluorescent dye indocyanine green (ICG) and the sirtuin 1 (Sirtl) activator SRT1720, and modified with a peptide moiety targeting osteopontin (OPN). The in vivo atherosclerotic mouse model was established with the high-fat diet (HFD). The in vitro vascular smooth muscle cells (VSMCs) phenotypic switching was induced using the ox-LDL stimulation. Results: Due to the overexpression of OPN in activated VSMCs and VASPs, the targeted NMs specifically accumulated within the VASPs region after intravenous injection into the atherosclerotic mice, achieving the precise detection of VASPs. In addition, in the presence of SRT1720, the NMs could activate intracellular Sirtl and activate an antiatherogenesis effect by inhibiting the phenotypic switching of VSMCs, which is an essential contributor to the vulnerability and progression of atherosclerotic plaques. After therapeutic administration of the ICG/SRT@HSA-pept NMs for two weeks, the physiological sizes and plaque compositions of VASPs were markedly improved. Furthermore, ICG/SRT@HSA-pept NMs-treated mice presented a more favorable plaque phenotype than that was observed in free SRT1720-treated mice, suggesting the enhanced delivery of pharmaceutical agents to the atherosclerotic lesions and improved therapeutic efficacy of NMs compared with free SRT1720. Conclusions: The theranostic ICG/SRT@HSA-pept NMs showed great potential for the precise identification and targeted treatment of atherosclerotic diseases.",

"abstract": "Objective This study aimed to compare the efficacy of Sonazoid and SonoVue in subjects with focal liver lesions. Methods The patients who had untreated focal solid liver lesions confirmed by B-mode ultrasonography were eligible for the study. The target lesion and whole liver were scanned by gray scale ultrasonography; then, contrast-enhanced ultrasonography was performed, and the results were evaluated blindly. The main end point was accuracy improvement with postcontrast versus precontrast ultrasound examination for diagnosis of the target lesion of interest as malignant or benign against the reference standard. Results There were 65 patients with 65 hepatic tumors enrolled in the study. The improvement of diagnostic accuracy was 0.30 in the Sonazoid group and 0.16 in the SonoVue group (95% confidence interval, -0.828-0.168; P = .24). Using 20% as the noninferiority margin, the upper limit of the 95% confidence interval (0.168) was less than 0.20. The number of lesions detected during the whole-liver scanning in the Sonazoid group was significantly more than that detected in the SonoVue group (P = .024). Conclusion The diagnosis value of Sonazoid is noninferior to SonoVue, and this new contrast agent can improves the whole-liver image quality.",

Methods: Thirty rabbits were randomly divided into three groups: control group (n=10, thoracotomy, left anterior descending artery was not ligated) and MI (n = 10, thoracotomy + MI, left anterior descending artery was ligated) group, and Carvedilol group (n = 10). The rabbits in the Carvedilol group received oral Carvedilol [5 mg/(kg · d)] for eight weeks. The rabbits in the other two groups received a matching saline. Eight weeks after operation, distribution of atrial connexin 40(Cx40) and its protein level were studied by immunohistochemistry and Western blot. Results: In MI group, atrial Cx40 level of left atrial appendage decreased significantly than that in control group (P<0. 01). The distribution Cx40 was changed. The side-to-side junctions increased, while the end-to-end junctions decreased. Atrial Cx40 in MI group was highly heterogeneous. In the Carvedilol group, the atrial Cx40 level increased significantly than that in MI group (P<0.05). Conclusion: Chronic left ventricular myocardial infarction can results in atrial Cx40 remodeling. Carvedilol can attenuate the Cx40 remodeling effectively.",

"abstract": "Objective: To evaluate the medium and long-term effects of radiofrequency catheter ablation (RFCA) on the hyptensive patients with premature ventricular contractions (PVCs). Methods: Radiofrequency catheter ablation (RFCA) was performed in 27 patients. The 24-hour ambulatory electrocardiographic monitoring, echocardiography, quality of life, healthcare resources utilization and cost were assessed at a screening visit and 3 and 12 months after RFCA. Patients were treated with RFCA and followed up over 6 months as outpatients. Cardiac troponin I(cTnI) level was repeatedly checked before and after RFCA. Results: Patients' PVCs were dramatically decreased to less than 1 000 beats per day by successful RFCA, left ventricular (LV) end-diastolic dimension (LVEDd) and end-systolic dimension (LVESd) measured by echocardiography had significant changes during the follow-up period (LV dimensions decreased significantly and LVEF increased significantly during the follow-up period as following: LVEDd: (44. 40 ± 5. 07) to (42.44 ± 5.60)mm, P<0. 01; LVESd: (33.07 ± 2.30) to (31. 66 ± 2. 20) mm, P<0. 01; LVEF: (56.07 ± 1.59) to (59.92 ± 1.49)%, P<0. 01); cTnI level: (0.15 ± 0. 19) to (1. 09 ± 0. 40)μg/L, P<0. 01, but still in normal range. This resulted in a significant improvement in quality of life at 3 and 12 months after the procedure. There were no major complications related to the procedure. It also reduced healthcare resource utilization and cost. Conclusion: Radiofrequency catheter ablation is a safe and effective treatment for hypertensive patients with premature ventricular contractions, and it is a viable alternation to drugs in the presence of disabling symptoms, and a protective method for hypertensive patients.",

"title": "Effects of irbesartan on atrial cell electrophysiology.",
"abstract": "Atrial fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice.~1 Its incidence increases with age and the presence of structural heart disease. It is a major cause of stroke, especially in the elderly. It has been shown that angiotensin converting enzyme inhibitor (ACEI) can reduce the incidence of AF after acute myocardial infarction.~2 Several studies have shown that activation of the rennin-angiotensin system is associated with the mechanisms of AF. Irbesartan is a long-acting angiotensin Ⅱ type 1 receptor antagonist used widely in the treatment of hypertension.~3 In recent years, it has been demonstrated that patients treated with amiodarone plus irbesartan had a lower rate of recurrence of atrial fibrillation than did patients treated with amiodarone alone.~4 These findings suggest that the inhibition of angiotensin Ⅱ may prevent AF, but its underlying electrophysiological mechanisms are obscure. The purpose of this study is to investigate the effects of irbesartan on atrial cell electrophysiology.",

"abstract": "Carvedilol, an antagonist of alpha1- and beta-adrenergic receptors, has shown efficacy in reducing all-cause death and arrhythmia death for ischemic heart disease and congestive heart failure in several large-scale trials. It has been found to prevent ventricular remodeling, and recently was reported to reverse down-regulation of Na+ channel in a chronic heart failure model. This study was conducted to investigate whether carvedilol could reverse the ion remodeling in a myocardial infarction model of rabbit.After the procedure of coronary ligation, animals were randomized to placebo or carvedilol treatment (5 mg/kg). Action potentials, L-type calcium current (Ica L) and the effect of isoproterenol stimulation on Ica L were measured using whole-cell patch method. Evaluation of the expression of calcium channel subunits was carried out by RT-PCR and Western blot.The results indicate that mean peak Ica L densities (pA/pF) at +10 mV was reduced in postinfarction myocytes (5.33 +/- 0.45, n = 25) compared to sham myocytes (6.52 +/- 0.21, n = 20). Treatment of myocardial infarction rabbits with carvedilol could restore it partially (5.91 +/- 0.39, n = 20, P < 0.05). However, steady-state activation parameters were similar in three groups. With stimulation by isoproterenol (1 micromol/L) Ica L increased in all three groups, but the increase was smaller in postinfarction myocytes. mRNA levels of calcium channel subunit CaA1 gene was decreased but CaB2a, CaB2b and CaB3 mRNA levels did not change after MI. Corresponding change in CaA1 protein was also observed.The results demonstrate that carvedilol restores Ica L density and reverse the downregulation of CaA1 postinfarction.",

"abstract": "The duck hepatitis B virus (DHBV) polymerase (P) is translated by de novo initiation from a downstream open reading frame (ORF) that partially overlaps the core (C) ORF on the bicistronic pregenomic RNA (pgRNA). The DHBV P AUG is in a poor context for translational initiation and is preceded by 14 AUGs that could intercept scanning ribosomes, yet P translation is unanticipatedly rapid. Therefore, we assessed C and P translation in the context of the pgRNA. Mutating the upstream C ORF revealed that P translation was inversely related to C translation, primarily due to occlusion of P translation by ribosomes translating C. Translation of the pgRNA was found to be cap dependent, because inserting a stem-loop (BamHI-SL) that blocked >90% of scanning ribosomes at the 5' end of the pgRNA greatly inhibited C and P synthesis. Neither mutating AUGs between the C and P start sites in contexts similar to that of the P AUG nor blocking ribosomal scanning by inserting the BamHI-SL between the C and P start codons greatly altered P translation, indicating that most ribosomes that translate P do not scan through these sequences. Finally, optimizing the P AUG context did not increase P translation. Therefore, the majority of the ribosomes that translate P are shunted from a donor region near the 5' end of the pgRNA to an acceptor site at or near the P AUG, and the shunt acceptor sequences may augment initiation at the P AUG.",

"abstract": "Silymarin, an extract from milk thistle (Silybum marianum), and its purified flavonolignans have been recently shown to inhibit hepatitis C virus (HCV) infection, both in vitro and in vivo. In the current study, we further characterized silymarin's antiviral actions. Silymarin had antiviral effects against hepatitis C virus cell culture (HCVcc) infection that included inhibition of virus entry, RNA and protein expression, and infectious virus production. Silymarin did not block HCVcc binding to cells but inhibited the entry of several viral pseudoparticles (pp), and fusion of HCVpp with liposomes. Silymarin but not silibinin inhibited genotype 2a NS5B RNA-dependent RNA polymerase (RdRp) activity at concentrations 5 to 10 times higher than required for anti-HCVcc effects. Furthermore, silymarin had inefficient activity on the genotype 1b BK and four 1b RDRPs derived from HCV-infected patients. Moreover, silymarin did not inhibit HCV replication in five independent genotype 1a, 1b, and 2a replicon cell lines that did not produce infectious virus. Silymarin inhibited microsomal triglyceride transfer protein activity, apolipoprotein B secretion, and infectious virion production into culture supernatants. Silymarin also blocked cell-to-cell spread of virus.Although inhibition of in vitro NS5B polymerase activity is demonstrable, the mechanisms of silymarin's antiviral action appear to include blocking of virus entry and transmission, possibly by targeting the host cell.",

"abstract": "Herpesviruses must cross the inner nuclear membrane and underlying lamina to exit the nucleus. HSV-1 US3 and PKC can phosphorylate lamins and induce their dispersion but do not elicit all of the phosphorylated lamin species produced during infection. UL13 is a serine threonine protein kinase conserved among many herpesviruses. HSV-1 UL13 phosphorylates US3 and thereby controls UL31 and UL34 nuclear rim localization, indicating a role in nuclear egress. Here, we report that HSV-2 UL13 alone induced conformational changes in lamins A and C and redistributed lamin B1 from the nuclear rim to intranuclear granular structures. HSV-2 UL13 directly phosphorylated lamins A, C, and B1 in vitro , and the lamin A1 tail domain. HSV-2 infection recapitulated the lamin alterations seen upon expression of UL13 alone, and other alterations were also observed, indicating that additional viral and/or cellular proteins cooperate with UL13 to alter lamins during HSV-2 infection to allow nuclear egress.",

"title": "Pre-P is a secreted glycoprotein encoded as an N-terminal extension of the duck hepatitis B virus polymerase gene.",
"abstract": "The duck hepatitis B virus (DHBV) pregenomic RNA is a bicistronic mRNA encoding the core and polymerase proteins. Thirteen AUGs (C2 to C14) and 10 stop codons (S1 to S10) are located between the C1 AUG for the core protein and the P1 AUG that initiates polymerase translation. We previously found that the translation of the DHBV polymerase is initiated by ribosomal shunting. Here, we assessed the biosynthetic events after shunting. Translation of the polymerase open reading frame was found to initiate at the C13, C14, and P1 AUGs. Initiation at the C13 AUG occurred through ribosomal shunting because translation from this codon was cap dependent but was insensitive to blocking ribosomal scanning internally in the message. C13 and C14 are in frame with P1, and translation from these upstream start codons led to the production of larger isoforms of P. We named these isoforms \"pre-P\" by analogy to the pre-C and pre-S regions of the core and surface antigen open reading frames. Pre-P was produced in DHBV16 and AusDHBV-infected duck liver and was predicted to exist in 80% of avian hepadnavirus strains. Pre-P was not encapsidated into DHBV core particles, and the viable strain DHBV3 cannot make pre-P, so it is not essential for viral replication. Surprisingly, we found that pre-P is an N-linked glycoprotein that is secreted into the medium of cultured cells. These data indicate that DHBV produces an additional protein that has not been previously reported. Identifying the role of pre-P may improve our understanding of the biology of DHBV infection.",

"abstract": "It was recently found that the Duck hepatitis B virus (DHBV) reverse transcriptase is primarily a non-encapsidated cytoplasmic molecule that is rapidly translated and has a very short half-life. Here, a non-encapsidated reverse transcriptase from the human Hepatitis B virus (HBV) was characterized. HBV polymerase accumulated in the cytoplasm in a manner similar to non-encapsidated DHBV polymerase. However, the HBV polymerase accumulated at an apparently lower concentration and had a longer half-life than the DHBV enzyme, and it displayed no evidence of the post-translational modifications observed for DHBV. Unlike the DHBV polymerase, immunofluorescence detection of the HBV polymerase in cells was suppressed by the core protein, and this suppression occurred independently of encapsidation. This implies an interaction between the polymerase and core in addition to encapsidation, but the polymerase and core did not co-immunoprecipitate, so the interaction might not be direct. These data indicate that production of cytoplasmic, non-encapsidated polymerase is conserved among the hepadnaviral genera. Furthermore, conservation of the cytoplasmic form of the polymerase suggests that it might have function(s) in virus replication or pathology beyond copying the viral genome.",

Here, we found that T3 is needed for P to bind the viral RNA, the first step in DNA synthesis. A second motif, RT-1, was predicted to assist T3. T3 and RT-1 appear to form a composite RNA binding site because mutating T3 and RT-1 had similar effects on RNA binding, exposure of antibody epitopes on P, and DNA synthesis. The T3 and RT-1 motifs bound RNA non-specifically, yet they were essential for specific interactions between P and the viral RNA. This implies that specificity for the viral RNA is provided by a post-binding step. The T3:RT-1 motifs are conserved with the human hepatitis B virus and may be an attractive target for novel antiviral drug development.",

"title": "Identification of an essential molecular contact point on the duck hepatitis B virus reverse transcriptase.",
"abstract": "The hepadnaviral polymerase (P) functions in a complex with viral nucleic acids and cellular chaperones. To begin to identify contacts between P and its partners, we assessed the exposure of the epitopes of six monoclonal antibodies (MAbs) to the terminal protein domain of the duck hepatitis B virus P protein in a partially denaturing buffer (RIPA) and a physiological buffer (IPP150). All MAbs immunoprecipitated in vitro translated P well in RIPA, but three immunoprecipitated P poorly in IPP150. Therefore, the epitopes for these MAbs were obscured in the native conformation of P but were exposed when P was in RIPA. Epitopes for MAbs that immunoprecipitated P poorly in IPP150 were between amino acids (aa) 138 and 202. Mutation of a highly conserved motif within this region (T3; aa 176 to 183) improved the immunoprecipitation of P by these MAbs and simultaneously inhibited DNA priming by P. Peptides containing the T3 motif inhibited DNA priming in a dose-dependent manner, whereas eight irrelevant peptides did not. T3 function appears to be conserved among the hepadnaviruses because mutating T3 ablated DNA synthesis in both duck hepatitis B virus and hepatitis B virus. These results indicate that (i) the conserved T3 motif is a molecular contact point whose ligand can be competed by soluble T3 peptides, (ii) the occupancy of T3 obscures the epitopes for three MAbs, and (iii) proper occupancy of T3 by its ligand is essential for DNA priming. Therefore, small-molecule ligands that compete for binding to T3 with its natural ligand could form a novel class of antiviral drugs.",

We previously found that the duck hepatitis B virus (DHBV) and hepatitis B virus reverse transcriptases (P protein) unexpectedly accumulate in the cytoplasm where they could affect function(s) beyond viral DNA synthesis, such as gene expression. Therefore, we measured effects of DHBV P on gene expression from reporter constructs and the viral genome. P reduced reporter expression at the mRNA level to approximately 30-40%, independent of reporter tested. Accumulation of the viral pregenomic RNA from its native promoter was suppressed three-to four-fold by P, and accumulation of the capsid protein and intracellular core particles was similarly suppressed because the pregenomic RNA encodes the capsid protein. Therefore, suppression of the pregenomic RNA by DHBV P creates a negative feedback loop to limit viral antigen accumulation and replication, possibly contributing to maintenance of chronic infection.",

However, the security of their scheme is based on the random oracle model. Up to now, there is no provably secure identity based universal designated verifier signature scheme in the standard model.

Their protocol (referred to as Protocol 2' in their paper) is the most efficient one among such identity-based authenticated key agreement protocols that provides perfect forward secrecy (PFS) with only 1 pairing evaluation for each protocol participant. But, each party needs to transmit 2 elliptic curve points to its partner. In this paper, we propose a new identity-based authenticated key agreement protocol which is not only more computationally efficient but also, most importantly, reduces the total communication overheads to 50%.

Although some work has been done in proxy-multi signature schemes, until now there is no formalized definition and security model for them. In this paper, we will give the formal definition and a security model of proxy-multi signature scheme.

"title": "An Identity Based Proxy Signature Scheme Secure in the Standard Model",
"abstract": "Identity-based proxy signature scheme is a special identity-based public key cryptography. In 2005, Gu and Zhu showed how to construct an identity-based proxy signature scheme from any secure identity-based signature scheme, but this construction need PKG to extract the secret proxy signing keys. David Galindo, Javier Herranz and Eike Kiltz proposed another generic construction of identity-based proxy signature scheme in Asiacrypt 2006. This construction method leads to schemes that are somewhat inefficient. This paper present the first direct construction of an identity based proxy signature scheme. Our scheme is based on an identity based signature scheme proposed by Paterson and Schuldt in 2006. The scheme's security is proven in the standard model and rests on the hardness of the computational Diffie-Hellman problem in groups equipped with a pairing.",

"abstract": "In recent years, human embryonic stem (hES) cells have become a promising cell source for regenerative medicine. Although hES cells have the ability for unlimited self-renewal, potential adverse effects of long-term cell culture upon hES cells must be investigated before therapeutic applications of hES cells can be realized. Here we investigated changes in molecular profiles associated with young (<60 passages) and old (>120 passages) cells of the H9 hES cell line as well as young (<85 passages) and old (>120 passages) cells of the PKU1 hES cell line. Our results show that morphology, stem cell markers, and telomerase activity do not differ significantly between young and old passage cells. Cells from both age groups were also shown to differentiate into derivatives of all 3 germ layers upon spontaneous differentiation in vitro. Interestingly, mitochondrial dysfunction was found to occur with prolonged culture. Old passage cells of both the H9 and PKU1 lines were characterized by higher mitochondrial membrane potential, larger mitochondrial morphology, and higher reactive oxygen species content than their younger counterparts. Teratomas derived from higher passage cells were also found to have an uneven preference for differentiation compared with tumors derived from younger cells. These findings suggest that prolonged culture of hES cells may negatively impact mitochondrial function and possibly affect long-term pluripotency.",

Mechanistically, the induction or repression of miRNAs occurring in cardiovascular dysfunction triggers downstream cardiac events in a cell-type-specific manner. More importantly, the endogenous microRNAs' disturbance can be modified to rescue cardiac function through exogenous overexpressing or neutralizing strategy. In this paper, we summarizes the current knowledge about miRNAs functions as well as their role in cardiac development and disease, and reports novel miRNAs-based therapeutic approaches to counteract maladaptive remodeling upon cardiac dysfunction.",

"abstract": "AIM: To compare the effect of intravenous infusion of recombinant human brain natriuretic peptide(rhBNP) on the hemodynamic profile and its clinical efficacy in patients with acute decompensated heart failure(ADHF).METHODS: Forty ADHF patients enrolled in our hospital were randomized equally to catheter group where hemodynamic changes were monitored with Swan-Ganz and noncatheter group(n=20 in each group).Pulmonary capillary wedge pressure(PCWP),pulmonary artery pressure(PAP) and right atrial pressure(RAP) were recorded and cardiac output(CO) and cardiac index(CI) were assessed by heat-sensitive dilution method before drug administration and 0.5,1,3,6 and 24 h after drug administration.Patients were divided into experiment group and control group and all patients received rhBNP with an initial i.v.bolus of 2 μg/kg followed by continuous i.v.titration of 0.01 μg/(kg·min) for 24 h.Dyspnea,overall symptom improvement in clinical conditions and fluid input and output were recorded before and 0.5,1,3,6 and 24 h after drug administration.RESULTS: The alleviation of dyspnea and overall symptoms were more significant in experimental group compared to those in control group,accompanied by enhanced natriuretic effect [(2.7±0.8) L vs.(1.7±0.4) L,P=0.01].Patients in the experiment group experienced more rapid,apparent,stable and long-lasting declines in PCWP and RAP,with significant difference between groups.No significant intergroup difference was found in PAP between groups and no inter-and intra-group significant differences were observed in CI.CONCLUSION: Compared with ADHF patients with less severe H2O/Na+ retention,ADHF patients with more serious H2O/Na+ retention have more favorable acute hemodynamic profile and better clinical response to rhBNP treatment.ADHF patients with severe H2O/Na+ retention may be the optimal target population for clinical application of rhBNP treatment.",

"abstract": "Although stem cell therapy holds promise for the regenerative treatment of ischemic heart disease,the tragic fate of engrafted stem cells is still a hurdle for the therapeutic effect.Previous studies showed that molecular imaging could be a realtime and quantitative effective approach to visualize and monitor stem cells,while vasoactive factors such as vascular endothelial growth factor(VEGF) may have protective effect on the stem cell.In this study,adipose tissue derived mesenchymal stem cells(ADMSCs),which stably expressed firefly luciferase gene,were cultured at the first step.Then bioluminescence imaging and other methods were used to visualize and quantify the ADMSCs' survival and proliferation,and confirmed whether VEGF pretreatment could affect the cells' viability.The results from bioluminescence imaging and quantitative analysis implied that VEGF pretreatment significantly enhanced the survival and proliferation of ADMSCs after hypoxia/reoxygenation injury in vitro,and prolonged ADMSCs' lifetime in vivo.Eventually,it concluded that reporter gene molecular imaging could be a direct,efficient and noninvasive strategy for monitoring the MSCs' biological process in vitro and in vivo,while it could well evaluate the effect of protective factors,such as VEGF,on MSCs with high efficacy.",

"abstract": "Objectives This study demonstrated the prognostic value of the residual SYNTAX score (rSS) for patients with chronic renal insufficiency (CRI). Background The rSS has been proposed as a useful tool for quantifying and stratifying the degree and complexity of residual stenosis and predicting long-term clinical outcomes following percutaneous coronary intervention (PCI). However, it has never been validated for patients with CRI. Methods A total of 2,468 consecutive patients with an estimated glomerular filtration rate 0 were defined as having incomplete revascularization and were stratified into the reasonable incomplete revascularization (RICR; 0 < rSS <= 8) group or the incomplete revascularization (ICR; rSS >8) group. Their outcomes were compared to those of the complete revascularization (CR) group. Results During follow-up (median, 3 years; range, 1.5-5 years), the ICR group had the highest incidence of all-cause death, cardiac death, myocardial infarction (MI), unplanned revascularization, stroke, and major adverse cardiovascular and cerebrovascular events (MACCE). Despite having higher rates of unplanned revascularization and MACCE, RICR group had comparable all-cause mortality, cardiac mortality, MI, and stroke with CR group. A multivariable Cox analysis indicated that rSS was an independent predictor of cardiac death, MI, unplanned revascularization, stroke, and MACCE. Furthermore, compared with baseline SYNTAX score, rSS had stronger prognostic accuracy when predicting the risk of unplanned revascularization, stroke, and MACCE at the 3-year follow-up. Conclusions The rSS is a powerful indicator of clinical outcomes and may help determine reasonable levels of revascularization for patients with CRI following PCI.",

Here, we constructed anti-MARCO NaGdF4:Yb,Er@NaGdF4 upconversion nanoparticles (UCNPs) by conjugating polyclonal MARCO antibody to the surface of NaGdF4:Yb,Er@NaGdF4 via condensation reaction. UCNPs displayed highly mono-dispersion with average sizes of 26.7 ± 0.8 nm and favorable biocompatibility. In vivo upconversion optical imaging revealed that distinctive fluorescence signal could be observed in the regions of carotid artery 10 min post-injection, reached peak value at 1 h and decreased back to baseline at 24 h post-injection. The carotid artery wall demonstrated high signal intensity on T1-weighted MR images after anti-MARCO UCNPs injection, as determined by 7.0T MRI. Immunofluorescence staining of tissue section of carotid artery revealed that MARCO was highly abundant in shoulder regions of plaque. Anti-MARCO UCNPs is a promising optical/MRI dual-modality imaging probe which can non-invasively reflect M1 phenotype macrophages behavior in vivo.",

"abstract": "The N-myc downstream-regulated gene 2 (NDRG2) is involved in cell apoptosis and survival. Although reported to be highly expressed in the cardiac tissue, the biological function of NDRG2 in the heart remains to be established. Insulin exerts protective effects against myocardial ischemia/reperfusion (I/R) injury through the PI3K/Akt pathway. Here, we examined the changes in phosphorylation of NDRG2, a novel substrate and phosphoprotein of Akt, in insulin-induced protection against myocardial I/R. Rat hearts were subjected to 30 min regional ischemia followed by reperfusion with or without insulin at the onset of reperfusion. Reperfusion with insulin inhibited myocardial apoptosis and reduced infarct size, as well as significantly up-regulated myocardial Akt and NDRG2 phosphorylation levels compared with the I/R group. These effects of insulin were blocked by pretreatment with the PI3K inhibitor wortmannin or Akt inhibitor. To further ascertain the role of NDRG2 in insulin-induced cardioprotection, cardiomyocytes were transduced with a lentivirus encoding shRNA targeting NDRG2 (loss-of-function), which rendered the cells more susceptible to I/R injury and significantly blunted the anti-apoptotic effect of insulin. Moreover, the NDRG2 shRNA lentivirus was tested in vivo, and NDRG2 knockdown aggravated myocardial I/R injury and attenuated the insulin-mediated cardioprotection against I/R injury. Taken together, these results suggest a novel role of PI3K/Akt/NDRG2 signaling in the cardioprotective effect of insulin.",

"abstract": "Electroacupuncture (EA) therapy has widely been accepted as a useful therapeutic technique with low risk in the clinical setting for prevention from cardiac disease. However, the physiological mechanism under which this protective effect works remains unclear. The present study investigated the effects of EA pretreatment on myocardial ischaemia/reperfusion (MI/R) injury in mice and its possible signalling pathway. Mice were randomly divided into Sham, MI/R, EA + MI/R, EA(-) + MI/R, and AM630 + EA + MI/R groups. We reported that EA pretreatment significantly ameliorated MI/R injury, evidenced by increased cardiac function, reduced infarct size, and decreased apoptosis. This was associated with a reduction of oxidative stress in the infarcted myocardium, which was through CB2. The CB2 expression was up-regulated in the heart after EA pretreatment, as well as heart tissue content of N-arach-idonoylethanolamine-anandamide and 2-arachidonylglycerol. Furthermore, the expression of adenosine monophosphate-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1 alpha) in the left ventricular myocardial tissue was decreased in the MI/R group, whereas increased in the EA pretreatment group. Administration of AM630 before EA pretreatment did not improve cardiac function and inhibit oxidative stress. Preinjection of AM630 or AMPK inhibitor compound C could partially decrease the expression of EA pretreatment-mediated AMPK or PGC-1 alpha. Pretreatment with EA increased the production of endocannabinoid, which elicited protective effects against MI/R injury through CB2 activation. The mechanism of this effect was related to the activation of AMPK/PGC-1 alpha pathway, followed by an inhibition of oxidative stress.",

"abstract": "PKC-beta inhibitor Ruboxistaurin (RBX or LY333531) can be used to reverse diabetic microvascular complication. However, it has not been previously established whether RBX can protect against ischemia/reperfusion (I/R) injury of cardiac microvessels in diabetic rats. STZ-induced diabetic rats were randomized into four groups and underwent I/R procedures. Cardiac barrier function and the region of cardiac microvascular lesion were examined. Cell monolayer barrier function was detected in cultured cardiac microvascular endothelial cells (CMECs) subjected to simulated I/R (SI/R). PKC-beta siRNA was transfected into CMECs to silence PKC-beta. Apoptosis Index of CMECs was detected by TUNEL assay and phosphor-LIMK2 protein expression was examined by Western blot analysis. RBX and insulin administration significantly reduced the cardiac microvascular lesion region and Apoptosis Index of endothelial cells (all P < 0.05 vs. no-treatment group). RBX decreased phosphor-LIMK2 expression (P < 0.05 vs. no-treatment group). RBX pretreatment and transfection with PKC-beta siRNA induced a rapid barrier enhancement in CMECs monolayer as detected by increased transendothelial electrical resistance (TER) and decreased FITC-dextran clearance (all P < 0.05 vs. no-treatment group). Meanwhile, RBX pretreatment and transfection with PKC-beta siRNA significantly decreased TUNEL positive CMECs and phosphor-LIMK2 expression in cultured CMECs (all P < 0.05 vs. no-treatment group). RBX pretreatment reduced F-actin/G-actin in cultured CMECs, reproducing the same effect as PKC-beta siRNA. These data indicate that PKC-beta inhibitor (RBX) may be helpful in attenuating the risk of severe cardiac microvascular I/R injury in diabetic rats partly due to its maintenance of endothelial barrier function and anti-apoptotic effect.",

"abstract": "Recent studies have shown that stem cell therapy can promote tissue regeneration; however, monitoring stem cells in vivo remains problematic owing to limitations of conventional histological assays and imaging modalities.Murine embryonic stem (ES) cells were stably transduced with a lentiviral vector carrying a novel triple-fusion (TF) reporter gene that consists of firefly luciferase, monomeric red fluorescence protein, and truncated thymidine kinase (fluc-mrfp-ttk). ES cell viability, proliferation, and differentiation ability were not adversely affected by either reporter genes or reporter probes compared with nontransduced control cells (P=NS). Afterward, 1x10(7) of ES cells carrying the TF reporter gene (ES-TF) were injected into the myocardium of adult nude rats (n=20). Control animals received nontransduced ES cells (n=6). At day 4, the bioluminescence and positron emission tomography signals in study animals were 3.7x10(7)+/-5.8x10(6) photons.s(-1).cm(-2) per steradian (sr) and 0.08+/-0.03% injected dose/g, respectively (P<0.05 versus control). Both signals increased progressively from week 1 to week 4, which indicated ES cell survival and proliferation in the host. Histological analysis demonstrated the formation of intracardiac and extracardiac teratomas. Finally, animals (n=4) that were treated with intraperitoneal injection of ganciclovir (50 mg/kg) did not develop teratomas when compared with control animals (n=4) treated with saline (1 mL/kg).This is the first study to characterize ES cells that stably express fluorescence, bioluminescence, and positron emission tomography reporter genes and monitor the kinetics of ES cell survival, proliferation, and migration. This versatile imaging platform should have broad applications for basic research and clinical studies on stem cell therapy.",

"title": "Protective effects of low-frequency magnetic fields on cardiomyocytes from ischemia reperfusion injury via ROS and NO/ONOO-.",
"abstract": "Background. Cardiac ischemia reperfusion (I/R) injury is associated with overproduction of reactive oxygen species (ROS). Low frequency pulse magnetic fields (LFMFs) have been reported to decrease ROS generation in endothelial cells. Whether LFMFs could assert protective effects on myocardial from I/R injury via ROS regulation remains unclear. Methods. To simulate in vivo cardiac I/R injury, neonatal rat cardiomyocytes were subjected to hypoxia reoxygenation (H/R) with or without exposure to LFMFs. Cell viability, apoptosis index, ROS generation (including O-2(-) and ONOO-), and NO production were measured in control, H/R, and H/R + LFMF groups, respectively. Results. H/R injury resulted in cardiomyocytes apoptosis and decreased cell viability, whereas exposure to LFMFs before or after H/R injury significantly inhibited apoptosis and improved cell viability (P < 0.05). LFMFs treatment could suppress ROS (including O-2(-) and ONOO-) generation induced by H/R injury, combined with decreased NADPH oxidase activity. In addition, LFMFs elevated NO production and enhanced NO/ONOO- balance in cardiomyocytes, and this protective effect was via the phosphorylation of endothelial nitric oxide synthase (eNOS). Conclusion. LFMFs could protect myocardium against I/R injury via regulating ROS generation and NO/ONOO- balance. LFMFs treatment might serve as a promising strategy for cardiac I/R injury.",

"abstract": "Human embryonic stem cells (hESCs) can serve as a potentially limitless source of cells that may enable regeneration of diseased tissue and organs. Here we investigate the use of human embryonic stem cell-derived cardiomyocytes (hESC-CMs) in promoting recovery from cardiac ischemia reperfusion injury in a mouse model. Using microarrays, we have described the hESC-CM transcriptome within the spectrum of changes that occur between undifferentiated hESCs and fetal heart cells. The hESC-CMs expressed cardiomyocyte genes at levels similar to those found in 20-week fetal heart cells, making this population a good source of potential replacement cells in vivo. Echocardiographic studies showed significant improvement in heart function by 8 weeks after transplantation. Finally, we demonstrate long-term engraftment of hESC-CMs by using molecular imaging to track cellular localization, survival, and proliferation in vivo. Taken together, global gene expression profiling of hESC differentiation enables a systems-based analysis of the biological processes, networks, and genes that drive hESC fate decisions, and studies such as this will serve as the foundation for future clinical applications of stem cell therapies.",

"title": "Can insulin resistance be reversed by insulin therapy?",
"abstract": "Insulin resistance (IR) is a state of decreased tissue sensitivity to insulin, which commonly exists in patients with metabolic syndrome and diabetes, and leads to compensatory hyperinsulinemia to maintain normoglycemia. It is characterized by pathway-specific inhibition of the PI3K/Akt signaling, which concerns the positive actions of insulin including glucose and lipid metabolism, while other pathways including the Ras/MAPK pathway, which accounts for the negative actions of insulin such as stimulation of smooth muscle proliferation and secretion of endothelin-1, stay unaffected. Thus it was concerned that insulin therapy may exacerbate the negative effects of insulin in IR states. However, treatment of diabetes with insulin in clinical practice showed uniformly beneficial rather than harmful results. So we hypothesize that insulin therapy may itself reverse insulin resistance, thus avoiding magnification of the MAPK pathway-related deleterious effects. The mechanisms may include the recently revealed anti-inflammatory effects of insulin as well as its conventional glucose and free fatty acids lowering effects, and possibly may also include changes in body fat distribution and plasma adiponectin level. Whether there are direct mechanisms that insulin therapy modulates insulin sensitivity remains to be investigated.",

"abstract": "To investigate the efficacy and proposed mechanism of bone marrow mononuclear cells (BMMNCs) transplantation for diabetic and non-diabetic patients with ST-segment elevation myocardial infarction (STEMI).One hundred and sixteen patients with STEMI who had successfully undergone percutaneous coronary intervention (PCI) were divided into a diabetic group (n=51) and non-diabetic group (n=65). All of the patients received intracoronary injection of BMMNCs.Diabetes down-regulated IGF-1, IGFBP-5, VEGF, SDF-1, IL-6, IL-1α and TNF-α expression and affected the expression of Bmi-1, Gfi1, Tel and Hox-B4 which could prevent premature senescence and maintain the self-renewal capacity of stem cells. Event-free survival rates were not statistically different between the diabetic and non-diabetic group (80% vs. 72.5%, p=0.382). LV ejection fraction (LVEF) and wall motion score index (WMSI) were evaluated by echocardiography and found to be significantly improved in the non-diabetic group compared to the diabetic group over the 4-year follow-up period. Improved myocardial perfusion and reduced infarct size in the non-diabetic group compared to the diabetic group was verified using single-photon emission computed tomographic (SPECT) imaging. The non-diabetic group also had reduced anginal symptoms as assessed by changes in their Seattle Angina Questionnaire scores and Canadian Cardiovascular Society (CCS) Functional Angina classification. An improvement of 6-minute walk distance (6MWD) was also noted to be higher in the non-diabetic group during the follow-up period.This study indicates that the beneficial effect of BMMNCs transplantation for STEMI is less pronounced in diabetic patients. The mechanism is associated with decreased BMMNCs function in diabetic patients.",

"abstract": "We aimed to compare the performance of FFRCT and FFRQCA in assessing the functional significance of coronary artery stenosis in patients suffering from coronary artery disease with stable angina. A total of 101 stable coronary heart disease (CAD) patients with 181 lesions were recruited. FFRCT and FFRQCA were compared using invasive fractional flow reserve (FFR) as a reference standard. Comparisons between FFRCT and FFRQCA were conducted based on strategies of the geometric reconstruction, boundary conditions, and geometric characteristics. The performance of FFRCT and FFRQCA in detecting hemodynamic significance was also investigated. The performance of FFRCT and FFRQCA in discriminating hemodynamically significant lesions was compared. Good correlation and agreement with invasive FFR was found using FFRCT and FFRQCA (r = 0.809, p < 0.001 and r = 0.755, p < 0.001). A significant difference was observed in the complex coronary artery tree, in which relatively better prediction was observed using FFRCT than FFRQCA when analyzing the stenosis distributed in the middle segment of a stenotic branch (p = 0.036). Moreover, FFRCT was found to be better at predicting hemodynamically insignificant stenosis than FFRQCA (p = 0.007), while the performance of the two parameters was similar in discriminating functional significant lesions using an FFR threshold of ≤ 0.8 as a reference standard. FFRCT and FFRQCA could both accurately rule out functional insignificant lesions in stable CAD patients. FFRCT was found to be better for the noninvasive screening of CAD patients with stable angina than FFRQCA. \n • FFR\n \n CT\n \n and FFR\n \n QCA\n \n were both in good correlation and agreement with invasive FFR measurements.\n \n • FFR\n \n CT\n \n is superior in accuracy and consistency compared to FFR\n \n QCA\n \n in patients with stenoses distributed in left coronary artery.\n \n • The noninvasive nature of FFR\n \n CT\n \n could provide potential benefit for stable CAD patients on disease management.",

"title": "Identification of angiogenesis and viable myocardium using hybrid cardiac imaging.",
"abstract": "The existing hybrid cardiac imaging approaches focus on predicting the adverse cardiac events or disease diagnosis, yet do not offer any insight into the pathological advance in the repair process. Angiogenesis is one of the most important mechanism in the repair process after ischemic injury and has shown benefit to the prognosis of occlusive cardiovascular disorders, thus becomes a target of molecular therapies. In vivo monitoring of angiogenesis and comprehensive evaluation of cardiac function associated with angiogenesis are urgently needed in both research and clinical practice. In this paper, a multimodality image fusion strategy was proposed for angiogenesis and viable myocardium identification. Imaging approaches including coronary computed tomography angiography(CCTA), 2-deoxy-2-[F-18]fluoro-D-glucose ([F-18]DG) PET/CT, [68Ga]-1,4,7-triazacyclononane-1,4,7-triacetic acid-(Arg-Gly-Asp)2 ([Ga-68]-NOTA-PRGD2) PET/CT and Tc-99m-sestamibi (Tc-99m-MIBI) myocardial perfusion SPECT/CT scanning were performed to acquire both anatomy and three kinds of function information. All of these modality images were then fused by an automatic strategy consisting of ROI segmentation and cross modality registration. The left ventricle myocardium was categorized into 4 groups based on fusion result according to the respective relative tracer uptake. The final results intuitively reflected the extent of the [F-18]DG and Tc-99m-MIBI uptake defect, the perfusion-metabolism mismatch area, as well as the location of the [Ga-68]-NOTA-PRGD2 signal. The hybrid CCTA-PET-SPECT image verified the occurrence of angiogenesis based on the in vivo noninvasive molecular imaging approaches and visualized the hibernating myocardium. The presented fusion strategy is helpful in facilitating the study of the relationship between viability, perfusion and blocked coronary arteries, as well as angiogenesis.",

To investigate the combination effects and mechanisms of valsartan (angiotensin II type 1 receptor blocker) and LAF237 (DPP-IV inhibitor) on prevention against oxidative stress and inflammation injury in db/db mice aorta. Methods. Db/db mice (n = 40) were randomized to receive valsartan, LAF237, valsartan plus LAF237, or saline. Oxidative stress and inflammatory reaction in diabetic mice aorta were examined. Results. Valsartan or LAF237 pretreatment significantly increased plasma GLP-1 expression, reduced apoptosis of endothelial cells isolated from diabetic mice aorta. The expression of NAD(P)H oxidase subunits also significantly decreased resulting in decreased superoxide production and ICAM-1 (fold change: valsartan : 7.5 +/- 0.7, P < 0.05; LAF237: 10.2 +/- 1.7, P < 0.05), VCAM-1 (fold change: valsartan : 5.2 +/- 1.2, P < 0.05; LAF237: 4.8 +/- 0.6, P < 0.05), and MCP-1 (fold change: valsartan: 3.2 +/- 0.6, LAF237: 4.7 +/- 0.8; P < 0.05) expression. Moreover, the combination treatment with valsartan and LAF237 resulted in a more significant increase of GLP-1 expression. The decrease of the vascular oxidative stress and inflammation reaction was also higher than monotherapy with valsartan or LAF237. Conclusion. These data indicated that combination treatment with LAF237 and valsartan acts in a synergistic manner on vascular oxidative stress and inflammation in type 2 diabetic mice.",

The aim of this study was to develop 18F-labeled bombesin analogs for PET of GRPR expression in prostate cancer xenograft models.[Lys3]Bombesin ([Lys3]BBN) and aminocaproic acid-bombesin(7-14) (Aca-BBN(7-14)) were labeled with 18F by coupling the Lys3 amino group and Aca amino group, respectively, with N-succinimidyl-4-18F-fluorobenzoate (18F-SFB) under slightly basic condition (pH 8.5). Receptor-binding affinity of FB-[Lys3]BBN and FB-Aca-BBN(7-14) was tested in PC-3 human prostate carcinoma cells. Internalization and efflux of both radiotracers were also evaluated. Tumor-targeting efficacy and in vivo kinetics of both radiotracers were examined in male athymic nude mice bearing subcutaneous PC-3 tumors by means of biodistribution and dynamic microPET imaging studies. 18F-FB-[Lys3]BBN was also tested for orthotopic PC-3 tumor delineation. Metabolic stability of 18F-FB-[Lys3]BBN was determined in mouse blood, urine, liver, kidney, and tumor homogenates at 1 h after injection.The typical decay-corrected radiochemical yield was about 30%-40% for both tracers, with a total reaction time of 150 +/- 20 min starting from 18F-. 18F-FB-[Lys3]BBN had moderate stability in the blood and PC-3 tumor, whereas it was degraded rapidly in the liver, kidneys, and urine. Both radiotracers exhibited rapid blood clearance. 18F-FB-[Lys3]BBN had predominant renal excretion. 18F-FB-Aca-BBN(7-14) exhibited both hepatobiliary and renal clearance. Dynamic microPET imaging studies revealed that the PC-3 tumor uptake of 18F-FB-[Lys3]BBN in PC-3 tumor was much higher than that of 18F-FB-Aca-BBN(7-14) at all time points examined (P < 0.01). The receptor specificity of 18F-FB-[Lys3]BBN in vivo was demonstrated by effective blocking of tumor uptake in the presence of [Tyr4]BBN. No obvious blockade was found in PC-3 tumor when 18F-FB-Aca-BBN(7-14) was used as radiotracer under the same condition. 18F-FB-[Lys3]BBN was also able to visualize orthotopic PC-3 tumor at early time points after tracer administration, at which time minimal urinary bladder activity was present to interfere with the receptor-mediated tumor uptake.This study demonstrates that 18F-FB-[Lys3]BBN and PET are suitable for detecting GRPR-positive prostate cancer in vivo.",

"title": "Moderate dose insulin promotes function of endothelial progenitor cells.",
"abstract": "EPCs (endothelial progenitor cells) regenerate the vascular endothelial cells and keep the integrity of the vascular endothelium and thus may retard the onset of atherosclerosis. Steady state levels of EPCs in the circulation were found to be correlated with cardiovascular event risks. Given the close relationship between insulin and the cardiovascular system, we tested the long-term effects of moderate-dose insulin treatment on bone marrow-derived EPCs. Rat bone marrow EPCs were exposed to various levels of insulin under normal (5 mmol/l) or high (40 mmol/l) glucose conditions for 7 days. Insulin at levels near the physiological range (0.1, 1 nmol/l) up-regulated EPCs proliferation, stimulated NO (nitric oxide) production and reduced EPC senescence and ROS (reactive oxygen species) generation under both normal- and high-glucose conditions. Glucose exerted deleterious effects on EPCs contrary to insulin. Western blot analysis suggested concomitant decrease of Akt phosphorylation and eNOS (endothelial nitric oxide synthase) expression by high-glucose treatment and increase with insulin administration. Thus, insulin promoted several activities of EPCs, which suggested a potential endothelial protective role of insulin. Akt/eNOS pathway may be involved in the modulation of EPCs function by glucose and insulin.",

"title": "FNDC5/irisin improves the therapeutic efficacy of bone marrow-derived mesenchymal stem cells for myocardial infarction.",
"abstract": "The beneficial functions of bone marrow mesenchymal stem cells (BM-MSCs) decline with decreased cell survival, limiting their therapeutic efficacy for myocardial infarction (MI). Irisin, a novel myokine which is cleaved from its precursor fibronectin type III domain-containing protein 5 (FNDC5), is believed to be involved in a cardioprotective effect, but little was known on injured BM-MSCs and MI repair yet. Here, we investigated whether FNDC5 or irisin could improve the low viability of transplanted BM-MSCs and increase their therapeutic efficacy after MI. BM-MSCs, isolated from dual-reporter firefly luciferase and enhanced green fluorescent protein positive (Fluc+–eGFP+) transgenic mice, were exposed to normoxic condition and hypoxic stress for 12 h, 24 h, and 48 h, respectively. In addition, BM-MSCs were treated with irisin (20 nmol/L) and overexpression of FNDC5 (FNDC5-OV) in serum deprivation (H/SD) injury. Furthermore, BM-MSCs were engrafted into infarcted hearts with or without FNDC5-OV. Hypoxic stress contributed to increased apoptosis, decreased cell viability, and paracrine effects of BM-MSCs while irisin or FNDC5-OV alleviated these injuries. Longitudinal in vivo bioluminescence imaging and immunofluorescence results illustrated that BM-MSCs with overexpression of FNDC5 treatment (FNDC5-MSCs) improved the survival of transplanted BM-MSCs, which ameliorated the increased apoptosis and decreased angiogenesis of BM-MSCs in vivo. Interestingly, FNDC5-OV elevated the secretion of exosomes in BM-MSCs. Furthermore, FNDC5-MSC therapy significantly reduced fibrosis and alleviated injured heart function. The present study indicated that irisin or FNDC5 improved BM-MSC engraftment and paracrine effects in infarcted hearts, which might provide a potential therapeutic target for MI.",

"abstract": "Apelin, a cytokine mainly secreted by adipocytes, is closely related with insulin resistance. The underlying molecular mechanisms of how apelin affects insulin resistance, however, are poorly understood. This study aimed to investigate the effect of apelin on glucose metabolism and insulin resistance in 3T3-L1 adipocytes. After 10 ng/ml TNF-α treatment for 24 h, insulin-stimulated glucose uptake was reduced by 47% in 3T3-L1 adipocytes. Apelin treatment improved glucose uptake in a time- and dose-dependent manner. Treatment of 1,000 nM apelin for 60 min maximally augmented glucose uptake in insulin-resistant 3T3-L1 adipocytes. Furthermore, apelin pre-incubation also increased adipocytes' insulin-stimulated glucose uptake, and PI3K/Akt pathway were involved in these effects. In addition, immunocytochemistry staining and western blotting analysis indicated that apelin could increase glucose transporter 4 translocation from the cytoplasm to the plasma membrane. Apelin also increased the anti-inflammatory adipokine adiponectin mRNA expression while reducing that of pro-inflammatory adipokine interleukin-6 in insulin-resistant 3T3-L1 adipocytes. These results suggest that apelin stimulates glucose uptake through the PI3K/Akt pathway, promotes GLUT4 translocation from the cytoplasm to the plasma membrane, and modulates inflammatory responses in insulin-resistant 3T3-L1 adipocytes.",

"abstract": "Numerous studies have demonstrated the potential use of stem cells for the repair and regeneration of injured tissues. However, tracking transplanted stem cell fate and function in vivo remains problematic. To address these issues, murine embryonic stem (ES) cells were stably transduced with self-inactivating lentiviral vectors carrying either a triple fusion (TF) or double fusion (DF) reporter gene construct. The TF consisted of monomeric red fluorescence protein (mrfp), firefly luciferase (Fluc), and herpes simplex virus truncated thymidine kinase (HSV-ttk) reporter genes. The DF consisted of enhanced green fluorescence protein (egfp) and Fluc reporter genes but lacked HSV-ttk. Stably transduced ES-TF or ES-DF cells were selected by fluorescence activated cell sorting based on either mrfp (TF) or egfp (DF) expression. Afterwards, cells were injected subcutaneously into the right (ES-TF cells) and left (ES-DF cells) shoulders of adult female nude mice. Cell survival was tracked noninvasively by bioluminescence and positron emission tomography imaging of Fluc and HSV-ttk reporter genes, respectively. Imaging signals progressively increased from day 2 to day 14, consistent with ES cell survival and proliferation in vivo. However, teratoma formation occurred in all nude mice after 5 weeks. Administration of ganciclovir (GCV), targeting the HSV-ttk gene, resulted in selective ablation of teratomas arising from the ES-TF cells but not ES-DF cells. These data demonstrate the novel use of multimodality imaging techniques to (1) monitor transplanted ES cell survival and proliferation in vivo and (2) assess the efficacy of suicide gene therapy as a backup safety measure against teratoma formation.",

"abstract": "Cardiac stem cell therapy remains hampered by acute donor cell death posttransplantation and the lack of reliable methods for tracking cell survival in vivo. We hypothesize that cells transfected with inducible vascular endothelial growth factor 165 (VEGF(165)) can improve their survival as monitored by novel molecular imaging techniques. Mouse embryonic stem (ES) cells were transfected with an inducible, bidirectional tetracycline (Bi-Tet) promoter driving VEGF(165) and renilla luciferase (Rluc). Addition of doxycycline induced Bi-Tet expression of VEGF(165) and Rluc significantly compared to baseline (p<0.05). Expression of VEGF(165) enhanced ES cell proliferation and inhibited apoptosis as determined by Annexin-V staining. For noninvasive imaging, ES cells were transduced with a double fusion (DF) reporter gene consisting of firefly luciferase and enhanced green fluorescence protein (Fluc-eGFP). There was a robust correlation between cell number and Fluc activity (R(2)=0.99). Analysis by immunostaining, histology, and RT-PCR confirmed that expression of Bi-Tet and DF systems did not affect ES cell self-renewal or pluripotency. ES cells were differentiated into beating embryoid bodies expressing cardiac markers such as troponin, Nkx2.5, and beta-MHC. Afterward, 5 x 10(5) cells obtained from these beating embryoid bodies or saline were injected into the myocardium of SV129 mice (n=36) following ligation of the left anterior descending (LAD) artery. Bioluminescence imaging (BLI) and echocardiography showed that VEGF(165) induction led to significant improvements in both transplanted cell survival and cardiac function (p<0.05). This is the first study to demonstrate imaging of embryonic stem cell-mediated gene therapy targeting cardiovascular disease. With further validation, this platform may have broad applications for current basic research and further clinical studies.",

"abstract": "Although adipose-derived stromal cell (ADSC) transplantation has been demonstrated as a promising therapeutic strategy for peripheral arterial disease (PAD), the mechanism of action behind the observed therapeutic efficacy of ADSCs remains unclear. This study was designed to investigate the long-term outcome and therapeutic behavior of engrafted ADSCs in a murine hindlimb ischemia model using multimodality molecular imaging approaches. ADSCs (1.0×10(7)) were isolated from Tg(Fluc-egfp) mice which constitutively express dual-reporter firefly luciferase and enhanced green fluorescent protein (Fluc(+)-eGFP(+), mADSCs(Fluc+GFP+)), then intramuscularly injected into the hindlimb of BALB/c-nu mice after unilateral femoral artery ligation and excision. Abbreviated survival (∼5 weeks) of post-transplant mADSCs within the ischemic hindlimb was longitudinally monitored using noninvasive bioluminescence imaging (BLI), fluorescence imaging (FRI), and bioluminescence tomography with micro-computed tomography (BLT/micro-CT). Use of the BLT/micro-CT system enabled quantitative 3-dimensional (3D) imaging of the cells' distribution and kinetics in vivo. Engrafted mADSCs improved blood perfusion recovery, ambulatory performance and prognosis of the ischemic hindlimb, probably by inducing angiogenesis and formation of collateral vessels, which could be visualized using laser Doppler perfusion imaging (LDPI), micro-CT angiography, vascular-cast imaging, and immunofluorescence. mADSCs augmented activation of the pro-angiogenic VEGF/mTOR/Akt pathway in vivo, even though the cells failed to incorporate into the host microvasculature as functional components. Downregulation of VEGF/mTOR/Akt signaling using small molecule inhibitors counteracted mADSC-induced angiogenesis and perfusion restoration. This study demonstrates for the first time the spatiotemporal kinetics and functional survival of transplanted mADSCs in a PAD model using in vivo 3D multimodality imaging. Our study indicates that mADSCs potentiate pro-angiogenic signal amplification via a VEGF/mTOR/Akt-dependent pathway, and thereby promote recovery from hindlimb ischemia.",

"abstract": "To explore the superiority of radiomics analysis in the diagnostic performance of coronary computed tomography angiography (CCTA) for identifying myocardial ischaemia and predicting major adverse cardiovascular events (MACE). A total of 105 lesions from 88 patients who underwent CCTA and invasive fractional flow reserve measurement were collected as the training set, and another 31 patients with CCTA and clinical outcome information were used as the validation set. Conventional CCTA features included the stenosis diameter, length, Agatston score and high-risk plaque characteristics. After extracting and selecting radiomics features, the robustness of the radiomics features was examined, and then conventional and radiomics models were established using logistic regressions. The area under the receiver operating characteristic (ROC) curve (AUC) and Net Reclassification Index (NRI) were analysed to compare the discrimination and classification abilities between the two models in both the training and validation sets. A total of 1409 radiomics features were extracted, and three wavelet features were finally screened out. The robustness test showed good stability for the refined radiomics features. Compared with the conventional model, the radiomics model displayed a significantly improved diagnostic performance in the training set (AUC 0.762 vs. 0.631, 95% confidence interval [CI] 0.671-0.853 vs. 0.519-0.742, P = 0.058) but a slightly improved diagnostic performance in the validation set (AUC 0.671 vs. 0.592, 95% CI 0.466-0.875 vs. 0.519-0.742, P = 0.448). The NRI of the radiomics model was increased in both the training and validation sets (NRI 0.198 and 0.238, respectively). Quantitative radiomics analysis was feasible and might help to improve the diagnostic performance of CCTA but is still controversial for predicting MACE.",

"abstract": "Pluripotent embryonic stem (ES) cells have the potential to form teratomas composed of derivatives from all three germ layers in animal models. This tumorigenic potential prevents clinical translation of ES cell research. In order to understand the biology and physiology of teratoma formation, we investigated the influence of undifferentiated ES cell number, migration, and long-term follow up after transplantation. Murine ES cells were stably transduced with a self-inactivating (SIN) lentiviral vector with a constitutive ubiquitin promoter driving a double-fusion (DF) reporter gene that consists of firefly luciferase and enhanced green fluorescent protein (Fluc-eGFP). To assess effects of cell numbers, varying numbers of ES-DF cells (1, 10, 100, 1,000, and 10,000) were injected subcutaneously into the dorsal regions of adult nude mice. To assess cell migration, 1 x 10(6) ES-DF cells were injected intramyocardially into adult Sv129 mice, and leakage to other extracardiac sites was monitored. To assess effects of long-term engraftment, 1 x 10(4) ES-DF cells were injected intramyocardially into adult nude rats, and cell survival response was monitored for 10 months. Our results show that ES-DF cells caused extracardiac teratoma in both immunocompetent and immunodeficient hosts; the lowest number of undifferentiated ES cells capable of causing teratoma was 500-1,000; and long-term engraftment could be shown for >300 days. Collectively, these results illustrate the potent tumorigenic potential of ES cells, which presents an enormous obstacle for future clinical studies.",

"title": "Comparison of reporter gene and iron particle labeling for tracking fate of human embryonic stem cells and differentiated endothelial cells in living subjects.",
"abstract": "Human embryonic stem (hES) cells are pluripotent stem cells capable of self-renewal and differentiation into virtually all cell types. Thus, they hold tremendous potential as cell sources for regenerative therapies. The concurrent development of accurate, sensitive, and noninvasive technologies capable of monitoring hES cells engraftment in vivo can greatly expedite basic research prior to future clinical translation. In this study, hES cells were stably transduced with a lentiviral vector carrying a novel double-fusion reporter gene that consists of firefly luciferase and enhanced green fluorescence protein. Reporter gene expression had no adverse effects on cell viability, proliferation, or differentiation to endothelial cells (human embryonic stem cell-derived endothelial cells [hESC-ECs]). To compare the two popular imaging modalities, hES cells and hESC-ECs were then colabeled with superparamagnetic iron oxide particles before transplantation into murine hind limbs. Longitudinal magnetic resonance (MR) imaging showed persistent MR signals in both cell populations that lasted up to 4 weeks. By contrast, bioluminescence imaging indicated divergent signal patterns for hES cells and hESC-ECs. In particular, hESC-ECs showed significant bioluminescence signals at day 2, which decreased progressively over the following 4 weeks, whereas bioluminescence signals from undifferentiated hES cells increased dramatically during the same period. Post-mortem histology and immunohistochemistry confirmed teratoma formation after injection of undifferentiated hES cells but not hESC-ECs. From these data taken together, we concluded that reporter gene is a better marker for monitoring cell viability, whereas iron particle labeling is a better marker for high-resolution detection of cell location by MR. Furthermore, transplantation of predifferentiated rather than undifferentiated hES cells would be more suited for avoiding teratoma formation.",

"abstract": "Objective: To investigate the effects of Rosuvastatin on the proliferation of adipose-derived mesenchymal stem cells (AD-MSCs)after hypoxia/reoxygenation (H/R) injury. Methods: AD-MSCs were isolated from Kunming mice and characterized by flowcytometry. AD-MSCs were divided into three groups: (1) control,(2) Hypoxia 6hrs+ Reoxygen 42hrs (H/R), (3) H/R+Rosuvastatin (10-8,10-7,10-6mol/L respectively). Cell proliferation was detected by MTT assays. The protein expressions of Akt, Akt, Erk and pErk were analyzed by Western blot assay. Results: The CD44 and CD90 of AD-MSCs were positive. Administration of Rosuvastatin in- creased proliferation of AD-MSCs after H/R injury (P<0.05). Western blot assay revealed that the levels of phosphorylated Akt and phos- phorylated Erk were higher in Rosuvastatin group than that in H/R group. Conclusion: Rosuvastatin promoted the proliferation of AD-MSCs after H/R injury by AKT and ERK.",

"title": "Activation of Melatonin Receptor 2 But Not Melatonin Receptor 1 Mediates Melatonin-conferred Cardio-protection Against Myocardial Ischemia/Reperfusion Injury.",
"abstract": "Accumulated pieces of evidence have proved the beneficial effects of melatonin on myocardial ischemia/reperfusion (MI/R) injury, and these effects were largely dependent on melatonin membrane receptor activation. In humans and other mammals, there are two types of melatonin receptors, including the melatonin receptor 1 (MT1, melatonin receptor 1a or MTNR1A) and melatonin receptor 1 (MT2, melatonin receptor 1b or MTNR1B) receptor subtypes. However, which receptor mediates melatonin-conferred cardioprotection remains unclear. In this study, we employed both loss-of-function and gain-of-function approaches to reveal the answer. Mice (wild-type; MT1 or MT2 silencing by in vivo minicircle vector; and those overexpressing MT1 or MT2 by in vivo AAV9 vector) were exposed to MI/R injury. Both MT1 and MT2 were present in wild-type myocardium. MT2, but not MT1, was essentially upregulated after MI/R Melatonin administration significantly reduced myocardial injury and improved cardiac function after MI/R Mechanistically, melatonin treatment suppressed MI/R-initiated myocardial oxidative stress and nitrative stress, alleviated endoplasmic reticulum stress and mitochondrial injury, and inhibited myocardial apoptosis. These beneficial actions of melatonin were absent in MT2-silenced heart, but not the MT1 subtype. Furthermore, AAV9-mediated cardiomyocyte-specific overexpression of MT2, but not MT1, mitigated MI/R injury and improved cardiac dysfunction, which was accompanied by significant amelioration of oxidative stress, endoplasmic reticulum stress, and mitochondrial dysfunction. Mechanistically, MT2 protected primary cardiomyocytes against hypoxia/reoxygenation injury via MT2/Notch1/Hes1/ROR alpha signaling. Our study presents the first direct evidence that the MT2 subtype, but not MT1, is a novel endogenous cardiac protective receptor against MI/R injury. Medications specifically targeting MT2 may hold promise in fighting ischemic heart disease.",

"abstract": "Tracking stem cell localization, survival, differentiation, and proliferation after transplantation in living subjects is essential for understanding stem cell biology and physiology. In this study, we investigated the long-term stability of reporter gene expression in an embryonic rat cardiomyoblast cell line and the role of epigenetic modulation on reversing reporter gene silencing. Cells were stably transfected with plasmids carrying cytomegalovirus promoter driving firefly luciferase reporter gene (CMV-Fluc) and passaged repeatedly for 3-8 months. Within the highest expressor clone, the firefly luciferase activity decreased progressively from passage 1 ( 843 +/- 28) to passage 20 ( 250 +/- 10) to passage 40 ( 44 +/- 3) to passage 60 ( 3 +/- 1 RLU/mu g; P < 0.05 vs. passage 1). Firefly luciferase activity was maximally rescued by treatment with 5-azacytidine ( DNA methyltransferase inhibitor) compared with trichostatin A ( histone deacetylase inhibitor) and retinoic acid ( transcriptional activator; P < 0.05). Increasing dosages of 5-azacytidine treatment led to higher levels of firefly luciferase mRNA ( RT-PCR) and protein ( Western blots) and inversely lower levels of methylation in the CMV promoter ( DNA nucleotide sequence). These in vitro results were extended to in vivo bioluminescence imaging (BLI) of cell transplant in living animals. Cells treated with 5-azacytidine were monitored for 2 wk compared with 1 wk for untreated cells ( P < 0.05). These findings should have important implications for reporter gene-based imaging of stem cell transplantation.",

"title": "Molecular imaging of p53 signal pathway in lung cancer cell cycle arrest induced by cisplatin.",
"abstract": "Cisplatin is a commonly employed chemotherapy drug for lung malignancy. However its efficacy is limited by acquired drug resistance and lacking of an in vivo real-time monitoring approach. The aim of this study is to investigate the effect of cisplatin on lung adenocarcinoma cell line p53-RE-Fluc/A549 in vivo via non-invasive reporter gene by molecular imaging. For this study, we employed p53-RE-Fluc/A549 cells that overexpressed a vector with three tandem repeats of p53 response element followed by the luciferase reporter gene. P53 activity was evaluated by optical imaging and verified by Western blot after cells were exposed to 10 µM cisplatin for 72 h. The cell cycle was mainly blocked at the S- and G2/M-phases after cisplatin treatment, whereas no significant change was observed in cell apoptotic index. Increased expression of p21 and Bcl-2 as well as decreased expression of Bax were observed after cisplatin treatment by Western blotting. Longitudinal in vivo bioluminescent imaging (BLI) revealed that the p53 activity was increased from 24 to 48 h after transient cisplatin treatment in p53-RE-Fluc/A549-bearing nude mice. RNA sequencing further revealed that cell cycle and p53 signaling pathway genes, such as E2F1, CCNA2, CDK1, and CCNE2 were significantly downregulated after long-term cisplatin treatment. Thus, our study showed that cisplatin exerts its cytotoxic effect through blockage of the cell cycle and may be partly regulated by the p53 signaling pathway. Furthermore, molecular imaging is a useful tool to investigate the mechanism and evaluate the effect of chemotherapy drugs both in vivo and in vitro.",

Following syngeneic intramuscular transplantation of 1 x 10(6) mESCs, the cells survived and differentiated into teratomas. In contrast, allogeneic mESC transplants were infiltrated by a variety of inflammatory cells, leading to rejection within 28 days. Acceleration of rejection was observed when mESCs were allotransplanted following prior sensitization of the host. Finally, we demonstrate that the mESC derivatives were more rapidly rejected compared to undifferentiated mESCs. These data show that mESCs do not retain immune-privileged properties in vivo and are subject to immunological rejection as assessed by novel molecular imaging approaches.",
