| 1 | Accelerated Degradation Reliability Modeling and Test Data Statistical Analysis of Aerospace Electrical Connector显示文摘As few or no failures occur during accelerated life test,it is difficult to assess reliability for long-life products with traditional life tests.Reliability assessment using degradation data of product performance over time becomes a significant approach.Aerospace electrical connector is researched in this paper.Through the analysis of failure mechanism,the performance degradation law is obtained and the statistical model for degradation failure is set up;according to the research on statistical analysis methods for degradation data,accelerated life test theory and method for aerospace electrical connector based on performance degradation is proposed by improving time series analysis method,and the storage reliability is assessed for Y11X series of aerospace electrical connector with degradation data from accelerated degradation test.The result obtained is basically consistent with that obtained from accelerated life test based on failure data,and the two estimates of product's characteristic life only have a difference of 8.7%,but the test time shortens about a half.As a result,a systemic approach is proposed for reliability assessment of highly reliable and long-life aerospace product. | CHEN Wenhua LIU Juan GAO Liang PAN Jun ZHOU Shengjun | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 22 |
| 2 | The development of China's Yangtze River Economic Belt:how to make it in a green way?显示文摘The Yangtze River is one of the largest and longest rivers in Asia.The river originates in the Tibet-Qinghai Plateau(headwater reach),passes through the mountainous provinces of Sichuan,Yunnan and Chongqing(upper reach),flows into the Central Plain(middle reach)and Lower Plain(lower reach),and finally empties into the East China Sea in Shanghai(estuary).The Yangtze River Economic Belt(YREB;Fig.1)has a surface area of 2.1 | Yushun Chen Shuanghu Zhang Desheng Huang Bai-Lian Li Junguo Liu Wenjin Liu Jing Ma Fang Wang Yong Wang Shengjun Wu Yegang Wu Jinyue Yan Chuanbo Guo Wei Xin Hao Wang | 2017 | Science Bulletin2017，62，9： | 20 |
| 3 | Benzoate anions-intercalated NiFe-layered double hydroxide nanosheet array with enhanced stability for electrochemical seawater oxidation显示文摘Seawater electrolysis is an extremely attractive approach for harvesting clean hydrogen energy,but detrimental chlorine species(i.e.,chloride and hypochlorite)cause severe corrosion at the anode.Here,we report our recent finding that benzoate anions-intercalated NiFe-layered double hydroxide nanosheet on carbon cloth(BZ-NiFe-LDH/CC)behaves as a highly efficient and durable monolithic catalyst for alkaline seawater oxidation,affords enlarged interlayer spacing of LDH,inhibits chlorine(electro)chemistry,and alleviates local pH drop of the electrode.It only needs an overpotential of 320 mV to reach a current density of 500 mA·cm^(−2)in 1 M KOH.In contrast to the fast activity decay of NiFe-LDH/CC counterpart during long-term electrolysis,BZ-NiFe-LDH/CC achieves stable 100-h electrolysis at an industrial-level current density of 500 mA·cm^(−2)in alkaline seawater.Operando Raman spectroscopy studies further identify structural changes of disorderedδ(NiIII-O)during the seawater oxidation process. | Longcheng Zhang Jie Liang Luchao Yue Kai Dong Jun Li Donglin Zhao Zerong Li Shengjun Sun Yongsong Luo Qian Liu Guanwei Cui Abdulmohsen Ali Alshehri Xiaodong Guo Xuping Sun | 2022 | Nano Research Energy2022，1，3： | 6 |
| 4 | Proteasome inhibition suppresses Th17 cell generation and ameliorates autoimmune development in experimental Sjögren’s syndrome显示文摘Immunoproteasome activation in immune cells is involved in the modulation of immune responses.Increasing evidence indicates that proteasome inhibitors show beneficial effects in treating autoimmune diseases,but it remains unclear whether proteasome inhibition is an effective approach for suppressing autoimmune development in Sjögren’s syndrome(SS).Our previous work has demonstrated a critical role for Th17 cells in the development of experimental SS(ESS)in mice.In this study,we detected high levels of low-molecular-weight protein 7(LMP7),a key subunit of the immunoproteasome,in Th17 cells from ESS mice.Moreover,treatment with bortezomib(BTZ),a proteasome inhibitor,markedly suppressed Th17 differentiation in both murine and human naive T cells in culture.Furthermore,ESS mice treated with BTZ displayed significantly higher saliva flow rates and a reduction in tissue destruction in the salivary glands compared with vehicle-treated ESS mice.Notably,BTZ-treated ESS mice showed markedly decreased Th17 cells,germinal center B cells and plasma cells in the peripheral lymphoid organs.In addition,adoptively transferred wild type naive CD4+T cells rapidly differentiated into Th17 cells and induced salivary dysfunction in IL-17-deficient mice immunized for ESS induction.However,BTZ treatment profoundly suppressed the donor T-cell-derived Th17 response and ameliorated the reduction in salivary secretion in IL-17-deficient recipient mice.Taken together,our findings demonstrate that proteasome inhibition can effectively ameliorate ESS by suppressing the Th17 response,which may contribute to the development of a novel therapeutic strategy for the treatment of SS. | Fan Xiao Xiang Lin Jie Tian Xiaohui Wang Qian Chen Ke Rui Jie Ma Shengjun Wang Qingwen Wang Xiaoqi Wang Dongzhou Liu Lingyun Sun Liwei Lu | 2017 | Cellular & Molecular Immunology2017，14，11： | 6 |
| 5 | Application of Lactic Acid Bacteria(LAB) in Freshness Keeping of Tilapia Fillets as Sashimi显示文摘Aquatic products are extremely perishable food commodities. Developing methods to keep the freshness of fish represents a major task of the fishery processing industry. Application of Lactic Acid Bacteria(LAB) as food preservative is a novel approach. In the present study, the possibility of using lactic acid bacteria in freshness keeping of tilapia fillets as sashimi was examined. Fish fillets were dipped in Lactobacillus plantarum 1.19(obtained from China General Microbiological Culture Collection Center) suspension as LAB-treated group. Changes in K-value, APC, sensory properties and microbial flora were analyzed. Results showed that LAB treatment slowed the increase of K-value and APC in the earlier storage, and caused a smooth decrease in sensory score. Gram-negative bacteria dominated during refrigerated storage, with Pseudomonas and Aeromonas being relatively abundant. Lactobacillus plantarum 1.19 had no obvious inhibitory effect against these Gram-negatives. However, Lactobacillus plantarum 1.19 changed the composition of Gram-positive bacteria. No Micrococcus were detected and the proportion of Staphylococcus decreased in the spoiled LAB-treated samples. The period that tilapia fillets could be used as sashimi material extended from 24 h to 48 h after LAB treatment. The potential of using LAB in sashimi processing was confirmed. | CAO Rong LIU Qi CHEN Shengjun YANG Xianqing LI Laihao | 2015 | Journal of Ocean University of China2015，14，4： | 5 |
| 6 | Ecto-mesenchymal stem cells: a new player for immune regulation and cell therapy显示文摘Extensive studies have demonstrated that mesenchymal stem cells(MSCs)are multipotent mesoderm-derived stromal cells that can differentiate into a variety of cell types,including adipocytes,osteoblasts,chondrocytes,myocytes and neuronal cells.1 MSCs are found in numerous organs and tissues,including bone marrow,heart,lung,muscle,peripheral blood,adipose tissue,cartilage,synovium,dental pulp,tonsil,umbilical cord,placenta,thymus and olfactory mucosa.1 MSCs have been shown to possess potent immunosuppressive functions and tissue repair capacities,which have facilitated the clinical applications of MSCs in treating a diverse range of disorders involving angiogenesis and fibrosis,including rheumatic diseases and graft-versus-host diseases.2,3 Here,we provide a brief commentary on newly emerging evidence of the immunoregulatory function and potential application of ecto-mesenchymal stem cells. | Ke Rui Xiang Lin Jie Tian Xiaohui Wang Lingyun Sun Xiaoping Hong Dongzhou Liu Shengjun Wang Liwei Lu | 2018 | Cellular & Molecular Immunology2018，15，1： | 4 |
| 7 | The Tibetan Plateau Surface–Atmosphere Coupling System and Its Weather and Climate Effects: The Third Tibetan Plateau Atmospheric Science Experiment显示文摘The Tibetan Plateau(TP) is a key area affecting forecasts of weather and climate in China and occurrences of extreme weather and climate events over the world. The China Meteorological Administration, the National Natural Science Foundation of China, and the Chinese Academy of Sciences jointly initiated the Third Tibetan Plateau Atmospheric Science Experiment(TIPEX-Ⅲ) in 2013, with an 8–10-yr implementation plan. Since its preliminary field measurements conducted in 2013, routine automatic sounding systems have been deployed at Shiquanhe, Gaize, and Shenzha stations in western TP, where no routine sounding observations were available previously. The observational networks for soil temperature and soil moisture in the central and western TP have also been established. Meanwhile, the plateau-scale and regional-scale boundary layer observations, cloud–precipitation microphysical observations with multiple radars and aircraft campaigns, and tropospheric–stratospheric air composition observations at multiple sites, were performed. The results so far show that the turbulent heat exchange coefficient and sensible heat flux are remarkably lower than the earlier estimations at grassland, meadow, and bare soil surfaces of the central and western TP. Climatologically, cumulus clouds over the main body of the TP might develop locally instead of originating from the cumulus clouds that propagate northward from South Asia. The TIPEX-Ⅲ observations up to now also reveal diurnal variations, macro-and microphysical characteristics, and water-phase transition mechanisms, of cumulus clouds at Naqu station. Moreover, TIPEX-Ⅲ related studies have proposed a maintenance mechanism responsible for the Asian 'atmospheric water tower' and demonstrated the effects of the TP heating anomalies on African, Asian, and North American climates. Additionally, numerical modeling studies show that the Γ distribution of raindrop size is more suitable for depicting the TP raindrop characteristics compared to the M–P distribution, the overestimation of sensible heat flux can be reduced via modifying the heat transfer parameterization over the TP, and considering climatic signals in some key areas of the TP can improve the skill for rainfall forecast in the central and eastern parts of China. Furthermore, the TIPEX-Ⅲ has been promoting the technology in processing surface observations, soundings, and radar observations, improving the quality of satellite retrieved soil moisture and atmospheric water vapor content products as well as high-resolution gauge–radar–satellite merged rainfall products, and facilitating the meteorological monitoring, forecasting, and data sharing operations. | Ping ZHAO Yueqing LI Xueliang GUO Xiangde XU Yimin LIU Shihao TANG Wenming XIAO Chunxiang SHI Yaoming MA Xing YU Huizhi LIU La JIA Yun CHEN Yanju LIU Jian LI Dabiao LUO Yunchang CAO Xiangdong ZHENG Junming CHEN An XIAO Fang YUAN Donghui CHEN Yang PANG Zhiqun HU Shengjun ZHANG Lixin DONG Juyang HU Shuai HAN Xiuji ZHOU | 2019 | Journal of Meteorological Research2019，33，3： | 4 |
| 8 | Tranexamic acid for acute intracerebral haemorrhage growth based on imaging assessment (TRAIGE): a multicentre, randomised, placebo- controlled trial显示文摘Background Studies show tranexamic acid can reduce the risk of death and early neurological deterioration after intracranial haemorrhage.We aimed to assess whether tranexamic acid reduces haematoma expansion and improves outcome in intracerebral haemorrhage patients susceptible to haemorrhage expansion.Methods We did a prospective,double-blind,randomised,placebo-controlled trial at 10 stroke centres in China.Acute supratentorial intracerebral haemorrhage patients were eligible if they had indication of haemorrhage expansion on admission imaging(eg,spot sign,black hole sign or blend sign),and were treatable within 8 hours of symptom onset.Patients were randomly assigned(1:1)to receive either tranexamic acid or a matching placebo.The primary outcome was intracerebral haematoma growth(>33% relative or>6 mL absolute)at 24 hours.Clinical outcomes were assessed at 90 days.Results Of the 171 included patients,124(72.5%)were male,and the mean age was 55.9±11.6 years.89 patients received tranexamic acid and 82 received placebo.The primary outcome did not differ significantly between the groups:36(40.4%)patients in the tranexamic acid group and 34(41.5%)patients in the placebo group had intracranial haemorrhage growth(OR 0.96,95% CI 0.52 to 1.77,p=0.89).The proportion of death was lower in the tranexamic acid treatment group than placebo group(8.1%vs 10.0%),but there were no significant differences in secondary outcomes including absolute intracranial haemorrhage growth,death and dependency.Conclusions Among patients susceptible to haemorrhage expansion treated within 8 hours of stroke onset,tranexamic acid did not significantly prevent intracerebral haemorrhage growth.Larger studies are needed to assess safety and efficacy of tranexamic acid in intracerebral haemorrhage patients. | Jingyi Liu Ximing Nie Hongqiu Gu Qi Zhou Haixin Sun Ying Tan Dacheng Liu Lina Zheng Jiahui Zhao Yan Wang Yibin Cao Haomeng Zhu Yunpeng Zhang Lijin Yi Yuehua Pu Miao Wen Zhonghua Yang Shengjun Sun Wenzhi Wang Xingquan Zhao Liping Liu Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，2： | 3 |

| 10 | Production of propene from 1-butene metathesis reaction on tungsten based heterogeneous catalysts显示文摘A new propene production route from 1-butene metathesis has been developed on heterogeneous 10WO3/Al2O3-HY catalysts with different HY contents.It is found that the catalysts play bi-functionally first for the isomerization of 1-butene to 2-butene and then for the cross-metathesis between 1-butene and 2-butene to propene and 2-pentene.The combination of HY zeolite and Al2O3 is prerequisite for the production of propene.The propene yield keeps increasing with the HY content in the range of 10-70 wt%,where 10WO3/Al2O3-70HY exhibits the highest propene yield.The MS-H2-TPR and MS-O2-TPO characterizations indicate that the increase of HY content in the catalysts weakens the interaction between W species and supports,whereas enhance the probability of coking on the metal species and acid sites. | Huijuan Liu Ling Zhang Xiujie Li Shengjun Huang Shenglin Liu Wenjie Xin Sujuan Xie Longya Xu | 2009 | Journal of Natural Gas Chemistry2009，18，3： | 3 |

| 13 | Haemostatic therapy in spontaneous intracerebral haemorrhage patients with high-risk of haematoma expansion by CT marker: a systematic review and meta- analysis of randomised trials显示文摘Background and purpose Current randomised controlled trials(RCTs)showed an uncertain benefit of haemostatic therapy on preventing haematoma expansion and improving the outcome in patients with intracerebral haemorrhage(ICH).This meta-analysis aims to systematically evaluate the effect of haemostatic agents on the prevention of haemorrhage growth in patients with high-risk spontaneous ICH predicted by CT signs in RCTs.Methods A comprehensive search of PubMed,EMBASE and Cochrane library from 1 January 2005 to 30 June 2021 was conducted.RCTs that compared haemostatic agents with placebo for the treatment of spontaneous patients with ICH with high-risk haemorrhage growth were included.The primary endpoint was haematoma expansion at 24 hours.Other major endpoints of interest included 90-day functional outcome and mortality.Results The meta-analysis included four RCTs that randomised 2666 patients with ICH with high-risk haemorrhage growth.Haemostatic therapy reduced the rate of haematoma expansion at a marginally statistically significant level when compared with placebo(OR 0.84;95% CI 0.70 to 1.00;p=0.051).Subgroup analysis for patients with black hole sign on CT revealed a significant reduction of haematoma expansion with haemostatic therapy(OR 0.61;95% CI 0.39 to 0.94;p=0.03).However,both the primary analysis and subgroup analyses showed that haemostatic therapy could not reduce the rate of poor functional outcome(modified Rankin Scale>3)or death.Conclusions Haemostatic therapy showed a marginally significant benefit in reducing early haematoma expansion in patients with high-risk spontaneous ICH predicted by markers on CT scan.However,no significant improvement in functional outcome or reduction of mortality was observed. | Ximing Nie Jingyi Liu Dacheng Liu Qi Zhou Wanying Duan Yuehua Pu Zhonghua Yang Miao Wen Haixin Sun Wenzhi Wang Shengjun Sun Hongqiu Gu Liping Liu | 2021 | Stroke & Vascular Neurology2021，6，2： | 2 |
| 14 | Hypocoagulation induced by broadspectrum antibiotics in extensive burn patients显示文摘Background:Patients with extensive burns usually develop pro-coagulation soon after the injury if there is no sepsis occurred.We describe the case of an extensive burn adult suffering from hypocoagulation not related to sepsis,but secondary to antibiotic treatment.Case presentation:Here,we report a case of an adult male patient suffering from flame burns of 45%total body surface area(40%full thickness)combined with inhalation injury.Hypocoagulopathy with soaring prolonged activated partial thromboplastin time value occurred on third week post-burn while systemic infection had been under control by application of broad-spectrum antibiotics.Investigations showed that not the infection but vitamin K-related coagulation factor deficiency were responsible for unexpected bleeding.However,supplemental vitamin K was not the key as we expected,which prompted us trying to decode the underlying cause of coagulation disturbance in this patient and pick out the most effective treatment for live-saving.After the withdrawal of highly suspected broad-spectrum antibiotic,Meropenem^(■),disturbed vitamin K related coagulation factors gradually restored to their optimal levels so as to maintain normal coagulation status.Therefore,surgical procedures without further risk of bleeding could be carried out in time for wound recovery.The patient was discharged on post-burn day 67 and transferred to a secondary hospital for his rehabilitation.Conclusion:Hypocoagulopathy may be devoted to different reasons other than sepsis in extensive burns.Early recognition of the cause for coagulation disturbance is critical to make appropriate treatment and save patients’lives.This case illustrated the importance of unveiling the mist cause for coagulation disturbance occurred in extensive burn patient,which paved the way for optimal life-saving treatments.And we also recommend burn surgeons to be alerted to antibiotic-induced vitamin K deficiency-related coagulopathy among critical burn patients. | Jian Liu Yiqing Liu Shengjun Liu Qin Zhang Jiexin Zheng Yiwen Niu Xuefeng Wang | 2019 | Burns & Trauma2019，7，1： | 2 |
| 15 | The stability of a novel weakly alkaline slurry of copper interconnection CMP for GLSI显示文摘Chemical mechanical polishing(CMP) is one of the important machining procedures of multilayered copper interconnection for GLSI, meanwhile polishing slurry is a critical factor for realizing the high polishing performance such as high planarization efficiency, low surface roughness. The effect of slurry components such as abrasive(colloidal silica), complexing agent(glycine), inhibitor(BTA) and oxidizing agent(H_2O_2) on the stability of the novel weakly alkaline slurry of copper interconnection CMP for GLSI was investigated in this paper. First, the synergistic and competitive relationship of them in a peroxide-based weakly alkaline slurry during the copper CMP process was studied and the stability mechanism was put forward. Then 1 wt% colloidal silica, 2.5 wt% glycine,200 ppm BTA, 20 m L/L H_2O_2 had been selected as the appropriate concentration to prepare copper slurry, and using such slurry the copper blanket wafer was polished. From the variations of copper removal rate, root-mean square roughness(Sq) value with the setting time, it indicates that the working-life of the novel weakly alkaline slurry can reach more than 7 days, which satisfies the requirement of microelectronics further development. | Caihong Yao Chenwei Wang Xinhuan Niu Yan Wang Shengjun Tian Zichao Jiang Yuling Liu | 2018 | Journal of Semiconductors2018，39，2： | 2 |
| 16 | N, O-doped carbon foam as metal-free electrocatalyst for efficient hydrogen production from seawater显示文摘Seawater electrolysis is the most promising technology for large scale hydrogen production due to the abundance and low cost of seawater in nature.However,compared with the traditional freshwater electrolysis,the issues of electrode poisoning and corrosion will occur during the seawater electrolysis process,and active and stable electrocatalysts for the hydrogen evolution reaction(HER)are thus highly desired.In this work,N,O-doped carbon foam in-situ derived from commercial melamine foam is proposed as a high-active metal-free HER electrocatalyst for seawater splitting.In acidic seawater,our catalyst shows high hydrogen generation performance with small overpotential of 161 mV at 10 mA·cm^(−2),a low Tafel slop of 97.5 mV·dec^(−1),and outstanding stability. | Qian Liu Shengjun Sun Longcheng Zhang Yongsong Luo Qin Yang Kai Dong Xiaodong Fang Dongdong Zheng Abdulmohsen Ali Alshehri Xuping Sun | 2022 | Nano Research2022，15，10： | 2 |

| 20 | An improved bearing fault detection strategy based on artificial bee colony algorithm显示文摘The operating state of bearing affects the performance of rotating machinery;thus,how to accurately extract features from the original vibration signals and recognise the faulty parts as early as possible is very critical.In this study,the one‐dimensional ternary model which has been proved to be an effective statistical method in feature selection is introduced and shapelet transformation is proposed to calculate the parameter of one‐dimensional ternary model that is usually selected by trial and error.Then XGBoost is used to recognise the faults from the obtained features,and artificial bee colony algorithm(ABC)is introduced to optimise the parameters of XGBoost.Moreover,for improving the performance of intelligent algorithm,an improved strategy where the evolution is guided by the probability that the optimal solution appears in certain solution space is proposed.The experimental results based on the failure vibration signal samples show that the average accuracy of fault signal recognition can reach 97%,which is much higher than the ones corresponding to traditional extraction strategies.And with the help of improved ABC algorithm,the performance of XGBoost classifier could be optimised;the accuracy could be improved from 97.02%to 98.60%compared with the traditional classification strategy. | Haiquan Wang Wenxuan Yue Shengjun Wen Xiaobin Xu Hans-Dietrich Haasis Menghao Su Ping liu Shanshan Zhang Panpan Du | 2022 | CAAI Transactions on Intelligence Technology2022，7，4： | 1 |
