1Size distributions and sources of elements in particulate matter at curbside,urban and rural sites in Beijing显示文摘Size distributions of 29 elements in aerosols collected at urban,rural and curbside sites in Beijing were studied.High levels of Mn,Ni,As,Cd and Pb indicate the pollution of toxic heavy metals cannot be neglected in Beijing.Principal component analysis (PCA) indicates 4 sources of combustion emission,crust related sources,traffic related sources and volatile species from coal combustion.The elements can be roughly divided into 3 groups by size distribution and enrichment factors method (EFs).Group 1 elements are crust related and mainly found within coarse mode including Al,Mg,Ca,Sc,Ti,Fe,Sr,Zr and Ba;Group 2 elements are fossil fuel related and mostly concentrated in accumulation mode including S,As,Se,Ag,Cd,Tl and Pb;Group 3 elements are multi-source related and show multi-mode distribution including Be,Na,K,Cr,Mn,Co,Ni,Cu,Zn,Ga,Mo,Sn and Sb.The EFs of Be,S,Cr,Co,Ni,Cu,Ga,Se,Mo,Ag,Cd,Sb,Tl and Pb show higher values in winter than in summer indicating sources of coal combustion for heating in winter.The abundance of Cu and Sb in coarse mode is about 2-6 times higher at curbside site than at urban site indicating their traffic sources.Coal burning may be the major source of Pb in Beijing since the phase out of leaded gasoline,as the EFs of Pb are comparable at both urban and curbside sites,and about two times higher in winter than that in summer.Jingchun Duan Jihua Tan Shulan Wang Jimin Hao Fahe Chai 2012Journal of Environmental Sciences2012,24,1:67
2Preliminary engineering application of microseismic monitoring technique to rockburst prediction in tunneling of Jinping Ⅱ project显示文摘Monitoring and prediction of rockburst remain to be worldwide challenges in geotechnical engineering.In hydropower,transportation and other engineering fields in China,more deep,long and large tunnels have been under construction in recent years and underground caverns are more evidently featured by 'long,large,deep and in group',which bring in many problems associated with rock mechanics problems at great depth,especially rockburst.Rockbursts lead to damages to not only underground structures and equipments but also personnel safety.It has been a major technical bottleneck in future deep underground engineering in China.In this paper,compared with earthquake prediction,the feasibility in principle of monitoring and prediction of rockbursts is discussed,considering the source zones,development cycle and scale.The authors think the feasibility of rockburst prediction can be understood in three aspects:(1) the heterogeneity of rock is the main reason for the existence of rockburst precursors;(2) deformation localization is the intrinsic cause of rockburst;and(3) the interaction between target rock mass and its surrounding rock mass is the external cause of rockburst.As an engineering practice,the application of microseismic monitoring techniques during tunnel construction of Jinping II Hydropower Station was reported.It is found that precursory microcracking exists prior to most rockbursts,which could be captured by the microseismic monitoring system.The stress concentration is evident near structural discontinuities(such as faults or joints),which shall be the focus of rockburst monitoring.It is concluded that,by integrating the microseismic monitoring and the rock failure process simulation,the feasibility of rockburst prediction is expected to be enhanced.Chun'an Tang Jimin Wang Jingjian Zhang 2010Journal of Rock Mechanics and Geotechnical Engineering2010,2,3:32

6Practices on rockburst prevention and control in headrace tunnels of Jinping II hydropower station显示文摘Rockburst problems induced by high in-situ stresses were prominent during construction of the headrace tunnels of Jinping II hydropower station. The rockbursts occurred in various forms, and it is necessary to take pertinent measures for integrated prevention and control of rockbursts. In view of the rockburst characteristics during tunnel construction of Jinping II hydropower station, the engineering geological conditions were presented, and the features, mechanisms and forms of rockbursts observed during construction were analyzed in detail. A large number of scientific researches, experiments and applications were conducted. Multiple measures were adopted to prevent and control rockbursts, including the prediction and early warning measures, stress relief by blasting in advance, optimized blasting design and optimized tunnel support in the tunnel sections prone to strong rockbursts. The effectiveness of these prevention and control measures was evaluated. Experiences have been accumulated through a great number of helpful explorations and practices for rockburst prevention and control. A comprehensive rockburst prevention and control system has been gradually established.Jimin Wang Xionghui Zeng Jifang Zhou 2012Journal of Rock Mechanics and Geotechnical Engineering2012,4,3:8
7The internalization pathway,metabolic fate and biological effect of superparamagnetic iron oxide nanoparticles in the macrophage-like RAW264.7 cell显示文摘The potential applications of superparamagnetic iron oxide nanoparticles (SPIONs) in several nanomedical fields have attracted intense interest based on the cell-nano interaction. However, the mechanisms underlying cell uptake, the intracellular trail, final fate and the biological effects of SPIONs have not yet been clearly elucidated. Here, we showed that multiple endocytic pathways were involved in the internalization process of SPIONs in the RAW264.7 macrophage. The internalized SPIONs were biocompatible and used three different metabolic pathways: The SPIONs were distributed to daughter cells during mitosis; they were degraded in the lysosome and free iron was released into the intracellular iron metabolic pool; and, the intact SPIONs were potentially exocytosed out of the cells. The internalized SPIONs did not induce cell damage but affected iron metabolism, inducing the upregulation of ferritin light chain at both the mRNA and protein levels and ferroportin 1 at the mRNA level. These results may contribute to the development of nanobiology and to the safe use of SPIONs in medicine when administered as a contrast medium or a drug delivery tool.GU JingLi XU HaiFei HAN YeHua DAI Wei HAO Wei WANG Chun Yu GU Ning XU HaiYan CAO JiMin 2011Science China(Life Sciences)2011,54,9:8
8Characteristics of distribution of Mycobacterium tuberculosis lineages in China显示文摘The genotyping methods of Mycobacterium tuberculosis would dramatically improve our understanding of the molecular epidemiology of tuberculosis. 3,929 isolates, from a National Survey of Drug-Resistant Tuberculosis in 2007 in China, were successfully genotyped by large sequence polymorphisms and 15 loci variable number tandem repeats. We found that 2,905(2,905/3,929, 73.9%) cases belonged to Lineage 2, dominated in the east and central regions, 975 cases(975/3,929, 24.8%) were Lineage 4, highly prevailed in the west regions, and 36 and 13 cases were Lineage 3 and Lineage 1, respectively. We also explored the associations between lineages(Lineage 2 vs. Lineage 4) and clinical characteristics by logistic regression. For Lineage 2, the risk factors were Han-ethnicity population and fever. However, for Lineage 4, they were occupation(farmer), and degree of education(non-literate). Fully understanding of the distribution of Mycobacterium tuberculosis lineage and its risk factors would play a critical role in tuberculosis prevention, control, and treatment.Haixia Chen Li He Chao Cai Jingyi Liu Junnan Jia Liang Ma Hairong Huang Lixia Wang Xumin Ni Jimin Gao Weimin Li 2018Science China(Life Sciences)2018,61,6:7
9Signal peptide replacements enhance expression and secretion of hepatitis C virus envelope glycoproteins显示文摘很多研究集中了于 glycoproteins E1 和针对 anti-HCV 疫苗和禁止者的发展的丙肝病毒(HCV ) 的 E2。E1/E2 表示和分泌物的改进为子单元疫苗开发为这些 glycoproteins 并且这样的描述是批评的。在这研究,我们设计了并且综合三信号肽基于联机节目 SignalP, TargetP,和 PSORT 定序,然后移开并且代替由重叠先于 E1/E2 的信号肽聚合酶链反应方法。我们在哺乳动物的房间在 E1/E2 表示和分泌物上估计了这改变的效果,用西方的污点分析,点污点,和 Galanthus nivalis 凝集素 lectin 俘获酶免疫分析。代替与织物 plasminogen 使活跃之物和 Gaussia 酶的信号肽先于 E1 和 E2 的肽在哺乳动物的房间导致了 E1/E2 表示和 E1 的分泌物的最大的改进,没有改变 glycosylation。如此的进展将帮助两个都便于 E1/E2 生物学的研究和一支有效 HCV 子单元疫苗的发展。在这研究使用的策略能在哺乳动物的房间被用于另外的 glycoproteins 的表示和生产基于线的系统。Bo Wen Yao Deng Jie Guan Weizheng Yan Yue Wang Wenjie Tan Jimin Gao 2011Acta Biochimica et Biophysica Sinica2011,43,2:6
10Efficient lung cancer-targeted drug delivery via a nanoparticle/MSC system显示文摘Low targeting efficiency limits the applications of nanoparticles in cancer therapy. The fact that mesenchymal stem cells(MSC) trapped in the lung after systemic infusion is a disadvantage for cell therapy purposes. Here, we utilized MSC as lung cancer-targeted drug delivery vehicles by loading nanoparticles(NP)with anti-cancer drug. MSC showed a higher drug intake capacity than fibroblasts. In addition, MSC showed predominant lung trapping in both rabbit and monkey. IR-780 dye, a fluorescent probe used to represent docetaxel(DTX) in NP, delivered via MSC accumulated in the lung. Both in vitro MSC/A549 cell experiments and in vivo MSC/lung cancer experiments validated the intercellular transportation of NP between MSC and cancer cells. In vivo assays showed that the MSC/NP/DTX drug delivery system exerted primary tumor inhibition efficiency similar to that of a NP/DTX drug system. Collectively, the MSC/NP drug delivery system is promising for lung-targeted drug delivery for the treatment of lung cancer and other lung-related diseases.Xusheng Wang Haiyan Chen Xiaowei Zeng Wenpeng Guo Yu Jin Shan Wang Ruiyun Tian Yanjiang Han Ling Guo Jimin Han Yaojiong Wu Lin Mei 2019Acta Pharmaceutica Sinica B2019,9,1:4
11Active sites in CO2 hydrogenation over confined VOx-Rh catalysts显示文摘Metal oxide-promoted Rh-based catalysts have been widely used for CO2 hydrogenation,especially for the ethanol synthesis.However,this reaction usually suffers low CO2 conversion and alcohols selectivity due to the formation of byproducts methane and CO.This paper describes an efficient vanadium oxide promoted Rh-based catalysts confined in mesopore MCM-41.The Rh-0.3VO/MCM-41 catalyst shows superior conversion(〜12%)and ethanol selectivity(〜24%)for CO2 hydrogenation.The promoting effect can be attributed to the synergism of high Rh dispersion by the confinement effect of MCM-41 and the formation of VOr-Rh interface sites.Experimental and theoretical results indicate the formation of til-CO at VOv-Rh interface sites is easily dissociated into*CH X,and then*CH X can be inserted by CO to form CH3,*CO followed by CH3*CO hydrogenation to ethanol.Guishuo Wang Ran Luo Chengsheng Yang Jimin Song Chuanye Xiong Hao Tian Zhi-Jian Zhao Rentao Mu Jinlong Gong 2019Science China Chemistry2019,62,12:4
12Engineering rock mechanics practices in the underground powerhouse at JinpingⅠhydropower station显示文摘Based on the analyses of data obtained from the underground powerhouse at Jinping Ⅰ hydropower station,a comprehensive review of engineering rock mechanics practice in the underground powerhouse is first conducted.The distribution of strata,lithology,and initial geo-stress,the excavation process and corresponding rock mass support measures,the deformation and failure characteristics of the surrounding rock mass,the stress characteristics of anchorage structures in the cavern complex,and numerical simulations of surrounding rock mass stability and anchor support performance are presented.The results indicate that the underground powerhouse of Jinping Ⅰ hydropower station is characterized by high to extremely high geo-stresses during rock excavation.Excessive surrounding rock mass deformation and high stress of anchorage structures,surrounding rock mass unloading damage,and local cracking failure of surrounding rock masses,etc.,are mainly caused by rock mass excavation.Deformations of surrounding rock masses and stresses in anchorage structures here are larger than those found elsewhere:20%of extensometers in the main powerhouse record more than 50 mm with the maximum at around 250 mm observed in the downstream sidewall of the transformer hall.There are about 25%of the anchor bolts having recorded stresses of more than 200 MPa.Jinping Ⅰ hydropower plant is the first to have an underground powerhouse construction conducted in host rocks under extremely high geo-stress conditions,with the ratio of rock mass strength to geo-stress of less than 2.0.The results can provide a reference to underground powerhouse construction in similar geological conditions.Aiqing Wu Jimin Wang Zhong Zhou Shuling Huang Xiuli Ding Zhihong Dong Yuting Zhang 2016Journal of Rock Mechanics and Geotechnical Engineering2016,8,5:4

15Galectin-3-centered paracrine network mediates cardiac inflammation and fibrosis upon β-adrenergic insult显示文摘Rapid over-activation of β-adrenergic receptors (β-AR) following acute stress initiates cardiac inflammation and injury by activating interleukin-18 (IL-18),however,the process of inflammation cascades has not been fully illustrated.The present study aimed to determine the mechanisms of cardiac inflammatory amplification following acute sympathetic activation.With bioinformatics analysis,galectin-3 was identified as a potential key downstream effector of β-AR and IL-18 activation.The serum level of galectin-3 was positively correlated with norepinephrine or IL-18 in patients with chest pain.In the heart of mice treated with β-AR agonist isoproterenol (ISO,5 mg kg^(-1)),galectin-3 expression was upregulated markedly later than IL-18 activation,and Nlrp3^(-/-)and Il18^(-/-)mice did not show ISO-induced galectin-3 upregulation.It was further revealed that cardiomyocyte-derived IL-18 induced galectin-3 expression in macrophages following ISO treatment.Moreover,galectin-3deficiency suppressed ISO-induced cardiac inflammation and fibrosis without blocking ISO-induced IL-18 increase.Treatment with a galectin-3 inhibitor,but not a β-blocker,one day after ISO treatment effectively attenuated cardiac inflammation and injury.In conclusion,galectin-3 is upregulated to exaggerate cardiac inflammation and injury following acute β-AR activation,a galectin-3 inhibitor effectively blocks cardiac injury one day after β-AR insult.Guomin Hu Jimin Wu Huijun Gu Xiangning Deng Wenli Xu Shan Feng Shuaixing Wang Yao Song Zhengda Pang Xiuling Deng Aleksandr E.Vendrov Nageswara R.Madamanchi Marschall S.Runge Xinyu Wang Youyi Zhang Han Xiao Erdan Dong 2023Science China(Life Sciences)2023,66,5:3
16Similarity law of fluctuating pressure spectrum beneath hydraulic jump显示文摘Similarity law is the conversion rule between model and prototype, on which a lot of research works have been done, with no agreement reached referring to the similarity law of fluctuating pressure fre- quency spectrum. Experimental data of peak frequency and dominant frequency range of fluctuating pressure spectrum beneath hydraulic jump obtained from serial models of scales 1:1, 1:2 and 1:5 are compared. As a result, similarity law of fluctuating pressure spectrum in the strongly rolling area agrees with the gravity law. As peak frequency and dominant frequencies of fluctuating pressures in hydraulic jump, toe and tail are rather low, and the similarity is often misunderstood to be λf = 1. However, the normalized spectrums of fluctuating pressures show that the similarity nearly agrees with the gravity law.LIAN JiJian WANG JiMin GU JinDe 2008Chinese Science Bulletin2008,53,14:3
17Multi-population and diffusion UMDA for dynamic multimodal problems显示文摘In dynamic environments,it is important to track changing optimal solutions over time.Univariate marginal distribution algorithm(UMDA) which is a class algorithm of estimation of distribution algorithms attracts more and more attention in recent years.In this paper a new multi-population and diffusion UMDA(MDUMDA) is proposed for dynamic multimodal problems.The multi-population approach is used to locate multiple local optima which are useful to find the global optimal solution quickly to dynamic multimodal problems.The diffusion model is used to increase the diversity in a guided fashion,which makes the neighbor individuals of previous optimal solutions move gradually from the previous optimal solutions and enlarge the search space.This approach uses both the information of current population and the part history information of the optimal solutions.Finally experimental studies on the moving peaks benchmark are carried out to evaluate the proposed algorithm and compare the performance of MDUMDA and multi-population quantum swarm optimization(MQSO) from the literature.The experimental results show that the MDUMDA is effective for the function with moving optimum and can adapt to the dynamic environments rapidly.Yan Wu Yuping Wang Xiaoxiong Liu Jimin Ye 2010Journal of Systems Engineering and Electronics2010,21,5:3
18Extraction of auroral oval boundaries from UVI images: A new FLICM clustering-based method and its evaluation显示文摘Based on the fuzzy local information c-means (FLICM) clustering algorithm, a new method is developed for extracting the equatorward and poleward boundaries of the auroral oval from images acquired by the Ultraviolet Imager (UVI) aboard the POLAR satellite. First, the method iteratively segments the UVI image with the FLICM clustering algorithm, according to an integrity criterion for the segmented auroral oval. Then, possible gaps in the extracted auroral oval are filled, based on prior knowledge of its shape. To evaluate the method objectively, the extracted boundaries are compared with the precipitating electron boundaries determined from DMSP satellite precipitation particle data. The evaluation results demonstrate that the proposed method generates more accurate auroral boundaries than traditional methods.WANG Qian MENG QingHu HU ZeJun XING ZanYang LIANG JiMin HU HongQiao 2011Advances in Polar Science2011,22,3:3
19First results on ^(76)Ge neutrinoless double beta decay from CDEX-1 experiment显示文摘We report the first results on ^(76)Ge neutrinoless double beta decay from stage one of the China dark-matter experiment(CDEX).A p-type point-contact high-purity germanium detector with a mass of 994 g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304 kg d has been analyzed over a wide spectral band from 500 keV to 3 MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039 MeV energy range. The half-life of ^(76)Ge neutrinoless double beta decay derived based on this result is T^(0ν)1/2>6.4×10^(22) yr(90% C.L.). An upper limit on the effective Majorana-neutrino mass of 5.0 eV has been achieved.Li Wang Qian Yue KeJun Kang JianPing Cheng YuanJing Li TszKing Henry Wong ShinTed Lin JianPing Chang JingHan Chen QingHao Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He QingJu He JinWei Hu HanXiong Huang TengRui Huang LiPing Jia Hao Jiang HauBin Li Hong Li JianMin Li Jin Li Jun Li Xia Li XueQian Li YuLan Li FongKay Lin ShuKui Liu Hao Ma JingLu Ma XingYu Pan Jie Ren XiChao Ruan ManBin Shen Vivek Sharma Lakhwinder Singh Manoj Kumar Singh Manoj Kumar Singh Arun Kumar Soma ChangJian Tang WeiYou Tang ChaoHsiung Tseng JiMin Wang Qing Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue LiTao Yang SongWei Yang Nan Yi ChunXu Yu HaiJun Yu WeiHe Zeng XiongHui Zeng Zhi Zeng Lan Zhang YunHua Zhang MingGang Zhao Wei Zhao JiFang Zhou ZuYing Zhou JingJun Zhu WeiBin Zhu ZhongHua Zhu 2017Science China(Physics,Mechanics & Astronomy)2017,60,7:3
