1Field experiment on a robust hierarchical metropolitan quantum cryptography network显示文摘A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and the corresponding application software shows a big step toward the practical user-oriented network with a high security level.XU FangXing CHEN Wei WANG Shuang YIN ZhenQiang ZHANG Yang LIU Yun ZHOU Zheng ZHAO YiBo LI HongWei LIU Dong HAN ZhengFu GUO GuangCan 2009Chinese Science Bulletin2009,54,17:40

5Burden of colorectal cancer in China, 1990-2017: Findings from the Global Burden of Disease Study 2017显示文摘Objective: Our goal is to analyze the trend of colorectal cancer(CRC) regarding the death, incidence and prevalence rates over time, and to provide epidemiological knowledge basis for health policy revision by comparing data about fatal outcomes of CRC in 2017 to those data in 1990, which was extracted from the Global Burden of Disease(GBD).Methods: The time trend and changes of CRC burden from 1990 to 2017 were measured by using the methods and results from the Institute for Health Metrics and Evaluation(IHME) GBD 2017, based on the rates of death,incidence and prevalence.Results: The death rate of CRC is 13.24/100,000, accounting for 1.79% of total deaths in China in 2017. In1990, CRC ranked 21 st in all causes of death in China compared to its 11 th ranking in 2017. The death, incidence and prevalence rate of CRC were standardized by the age scale of the global population in 2010, the change of standardized death rate of CRC was not significant, from 9.33/100,000 in 1990 to 10.10/100,000 in 2017. The standardized incidence rate of CRC significantly increased from 12.18/100,000 in 1990 to 22.42/100,000 in 2017.The standardized prevalence rate of CRC significantly increased from 44.55/100,000 in 1990 to 118.40/100,000 in2017. The trend of the prevalence rate in both genders grow higher in 2017 compared to the 1990, resulting in141.6%, 209.8% and 189.0% for the studied three age groups(15-49, 50-69 and 70+ years old), respectively. The death rate increased in the age groups of 50-69 and 70+ years in both genders(8.6% and 31.0% respectively), in contrast to a decrease of death rate in the age group of 15-49 years old(-10.8%).Conclusions: China experienced a stunning increase in terms of incidence and prevalence rate of CRC from1990 to 2017. To decrease the burden of CRC, prevention and management of known risk factors should be promoted through national polices.Jie Yin Zhigang Bai Jun Zhang Zhi Zheng Hongwei Yao Pengpeng Ye Jun Li Xin Gao Zhongtao Zhang 2019Chinese Journal of Cancer Research2019,31,3:16
6miR-181b functions as an oncomiR in colorectal cancer by targeting PDCDZ显示文摘Yanqing Liu Uzair-ur-Rehman Yu Guo Hongwei Liang Rongjie Cheng Fei Yang Yeting Hong Chihao Zhao Minghui Liu Mengchao Yu Xinyan Zhou Kai Yin Jiangning Chen Junfeng Zhang Chen-Yu Zhang Feng Zhi Xi Chen 2016Protein & Cell2016,7,10:14
7Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12

10Multiparty-controlled teleportation of an arbitrary GHZ-class state by using a d-dimensional (N+2)-particle nonmaximally entangled state as the quantum channel显示文摘We present a scheme for multiparty-controlled teleportation of an arbitrary high-dimensional GHZ-class state with a d-dimensional (N+2)-particle GHZ state following some ideas from the teleportation (Chinese Physics B, 2007, 16: 2867). This scheme has the advantage of transmitting much fewer particles for controlled teleportation of an arbitrary multiparticle GHZ-class state. Moreover,we discuss the application of this scheme by using a nonmaximally entangled state as its quantum channel.LONG LiuRong LI HongWei ZHOU Ping FAN Chao YIN CaiLiu 2011Science China(Physics,Mechanics & Astronomy)2011,54,3:7
11Two-Dimensional Ground Deformation Monitoring in Shanghai Based on SBAS and MSBAS InSAR Methods显示文摘Shanghai has experienced the greatest land subsidence in China in the past sixty years and produced undesirable environmental impact. However, horizontal ground deformation has not been understood yet. Therefore ground deformation monitoring together with the analysis of its driving forces are critical for geo-hazards early-warning, city planning and sustainable urbanization in Shanghai. In this paper, two-dimensional ground deformation monitoring was performed in Shanghai with SBAS and MSBAS In SAR methods. Twenty-nine Multi-Look Fine 6(MF6) Radarsat-2 SLC data acquired during 2011–2013 were used to derive vertical ground deformation. Meanwhile, six descending Multi-Look Fine 6(MF6) and four ascending Multi-Look Fine 2(MF2) spanning April to August, 2008, were used to derive vertical and horizontal ground deformation during the observation period. The results indicate that vertical and horizontal deformations in 2008 were not homogeneously distributed in different districts ranging from 0–2 cm/year. Vertical deformation rates during 2011–2013 were decreased to less than 1 cm/year in most district of Shanghai area. Activities from groundwater exploitation and rapid urbanization are responsible for most of the ground deformation in Shanghai. Thus, future ground deformation in vertical and horizontal directions should be warranted.Shaochun Dong Sergey Samsonov Hongwei Yin Lulu Huang 2018Journal of Earth Science2018,29,4:6
12Effects of redox potential on soil cadmium solubility:Insight into microbial community显示文摘Understanding the role of microbes in the solubility of cadmium(Cd) is of fundamental importance for remediation of Cd toxicity. The present study aimed to identify the microbes that involved in regulating Cd solubility and to reveal possible mechanisms. Therefore,microbial communities were investigated through high-throughput sequencing approach, the molecular ecological network was constructed and metagenomes were predicted. Our results indicated that redox conditions affected both the solubility of soil Cd and the microbial communities. Anaerobic microbes, such as Anaerolineaceae, did not only play important roles in shaping the microbial community in soils, but might also be involved in regulating the Cd solubility. Two possible mechanisms that how Anaerolineaceae involved in Cd solubility are(1) Anaerolineaceae are important organic matter degraders under anoxic conditions and(2) Anaerolineaceae can co-exist with methane metabolism microbes, while methane metabolism promotes the precipitation of soluble Cd. Thus, application of Anaerolineaceae in bioremediation of soil Cadmium contamination is a potential approach. The study provided a novel insight into the role of microbial community in the regulation of Cd solubility under different redox conditions, and suggested a potential approach for the remediation of soil Cd contamination.Delong Meng Juan Li Tianbo Liu Yongjun Liu Mingli Yan Jin Hu Xiaoqi Li Xueduan Liu Yili Liang Hongwei Liu Huaqun Yin 2019Journal of Environmental Sciences2019,31,1:6
13CONTROL OF VEHICLE PLATOONS FOR HIGHWAY SAFETY AND EFFICIENT UTILITY:CONSENSUS WITH COMMUNICATIONS AND VEHICLE DYNAMICS显示文摘Platoon formation of highway vehicles is a critical foundation for autonomous or semiautonomous vehicle control for enhanced safety,improved highway utility,increased fuel economy,and reduced emission toward intelligent transportation systems.Platoon control encounters great challenges from vehicle control,communications,team coordination,and uncertainties.This paper introduces a new method for coordinated control of platoons by using integrated network consensus decisions and vehicle control.To achieve suitable coordination of the team vehicles based on terrain and environmental conditions,the emerging technology of network consensus control is modified to a weighted and constrained consensus-seeking framework.Algorithms are introduced and their convergence properties are established.The methodology employs neighborhood information through on-board sensors and V2 V or V2 I communications,but achieves global coordination of the entire platoon.The ability of the methods in terms of robustness,disturbance rejection,noise attenuation,and cyber-physical interaction is analyzed and demonstrated with simulated case studies.WANG Le Yi SYED Ali YIN Gang George PANDYA Abhilash ZHANG Hongwei 2014Journal of Systems Science & Complexity2014,27,4:5
14Follistatin-like protein 1 plays a tumor suppressor role in clear-cell renal cell carcinoma显示文摘Background:We previously showed that the expression of follistatin-like protein 1(FSTL1)was significantly down-regulated in metastatic clear-cell renal cell carcinoma(ccRCC).In this study,we aimed to characterize the role of FSTL1 in the development of ccRCC.Methods:The effects of FSTL1 on cell activity and cell cycle were investigated in ccRCC cell lines with altered FSTL1 expression.Gene expression microarray assays were performed to identify the major signaling pathways affected by FSTL1 knockdown.The expression of FSTL1 in ccRCC and its effect on postoperative prognosis were estimated in a cohort with 89 patients.Results:FSTL1 knockdown promoted anchorage-independent growth,migration,invasion,and cell cycle of ccRCC cell lines,whereas FSTL1 overexpression attenuated cell migration.FSTL1 knockdown up-regulated nuclear factor-κB(NF-κB)and hypoxia-inducible factor(HIF)signaling pathways,increased epithelial-to-mesenchymal transition,up-regulated interleukin-6 expression,and promoted tumor necrosis factor-α-induced degradation of NF-κB inhibitor(IκBα)in ccRCC cell lines.FSTL1 immunostaining was selectively positive in epithelial cytoplasm in the loop of Henle,and positive rate of FSTL1 was significantly lower in ccRCC tissues than in adjacent renal tissues(P<0.001).The mul-tivariate Cox regression analysis showed that the intratumoral FSTL1 expression conferred a favorable independent prognosis with a hazard ratio of 0.325(95%confidence interval 0.118-0.894).HIF-2αexpression was negatively cor-related with FSTL1 expression in ccRCC specimens(r=−0.229,P=0.044).Intratumoral expression of HIF-2α,rather than HIF-1α,significantly predicted an unfavorable prognosis in ccRCC(log-rank,P=0.038).Conclusions:FSTL1 plays a tumor suppression role possibly via repressing the NF-κB and HIF-2αsignaling pathways.To increase FSTL1 expression might be a candidate therapeutic strategy for metastatic ccRCC.Yan Liu Xiaojie Tan Wenbin Liu Xi Chen Xiaomei Hou Dan Shen Yibo Ding Jianhua Yin Ling Wang Hongwei Zhang Yongwei Yu Jianguo Hou Timothy C.Thompson Guangwen Cao 2018Cancer Communications2018,38,1:5
15Microstructural evolution of carbon fiber reinforced SiC-based matrix composites during laser ablation process显示文摘In this work, four different carbon fiber reinforced SiC-based matrix composites(C/SiC) were prepared,and microstructure evolution during laser ablation process was characterized. Laser irradiation provided a special high-temperature environment up to 3500℃. For all four composites, different morphologies can be obtained in the transition region due to the oxidation of different matrices. While only needle-shaped carbon fiber and nanolayered carbon without any matrix remained in the central region, indicating that graphitization process occurred in the center, resulting from the high-temperature and low-oxygen environment in the laser process. Therefore, the laser ablation of C/SiC composites is controlled by chemical and physical erosion, and mainly by the physical erosion in the center.Xiaolin Dang Xiaowei Yin Xiaomeng Fan Yuzhao Ma Jiangtao Wang Panfei Ju Hongwei Song 2019Journal of Materials Science & Technology2019,35,12:4
16Three-dimensional distinct element modeling of fault reactivation and induced seismicity due to hydraulic fracturing injection and backflow显示文摘This paper presents a three-dimensional fully hydro-mechanical coupled distinct element study on fault reactivation and induced seismicity due to hydraulic fracturing injection and subsequent backflow process,based on the geological data in Horn River Basin,Northeast British Columbia,Canada.The modeling results indicate that the maximum magnitude of seismic events appears at the fracturing stage.The increment of fluid volume in the fault determines the cumulative moment and maximum fault slippage,both of which are essentially proportional to the fluid volume.After backflow starts,the fluid near the joint intersection keeps flowing into the critically stressed fault,rather than backflows to the wellbore.Although fault slippage is affected by the changes of both pore pressure and ambient rock stress,their contributions are different at fracturing and backflow stages.At fracturing stage,pore pressure change shows a dominant effect on induced fault slippage.While at backflow stage,because the fault plane is under a critical stress state,any minor disturbance would trigger a fault slippage.The energy analysis indicates that aseismic deformation takes up a majority of the total deformation energy during hydraulic fracturing.A common regularity is found in both fracturing-and backflow-induced seismicity that the cumulative moment and maximum fault slippage are nearly proportional to the injected fluid volume.This study shows some novel insights into interpreting fracturing-and backflowinduced seismicity,and provides useful information for controlling and mitigating seismic hazards due to hydraulic fracturing.Zirui Yin Hongwei Huang Fengshou Zhang Lianyang Zhang Shawn Maxwell 2020Journal of Rock Mechanics and Geotechnical Engineering2020,12,4:4
17Cytosolic delivery of the immunological adjuvant PolyⅠ:C and cytotoxic drug crystals via a carrier-free strategy significantly amplifies immune response显示文摘Co-delivery of chemotherapeutics and immunostimulant or chemoimmunotherapy is an emerging strategy in cancer therapy.The precise control of the targeting and release of agents is critical in this methodology.This article proposes the asynchronous release of the chemotherapeutic agents and immunostimulants to realize the synergistic effect between chemotherapy and immunotherapy.To obtain a proof-of-concept,a co-delivery system was prepared via a drug-delivering-drug(DDD)strategy for cytosolic co-delivery of Poly I:C,a synthetic ds RNA analog to activate RIG-I signaling,and PTX,a commonly used chemotherapeutics,in which pure PTX nanorods were sequentially coated with Poly I:C and mannuronic acid via stimulating the RIG-I signaling axis.The co-delivery system with a diameter of 200 nm enables profound immunogenicity of cancer cells,exhibiting increased secretion of cytokines and chemokines,pronounced immune response in vivo,and significant inhibition of tumor growth.Also,we found that intracellularly sustained release of cytotoxic agents could elicit the immunogenicity of cancer cells.Overall,the intracellular asynchronous release of chemotherapeutics and immunomodulators is a promising strategy to promote the immunogenicity of cancer cells and augment the antitumor immune response.Xiaoqing Du Yuqi Hou Jia Huang Yan Pang Chenlu Ruan Wei Wu Chenjie Xu Hongwei Zhang Lifang Yin Wei He 2021Acta Pharmaceutica Sinica B2021,11,10:3
18Co-expression Analysis Identifies CRC and AP1 the Regulator of Arabidopsis Fatty Acid Biosynthesis显示文摘Fatty acids (FAs) play crucial rules in signal transduction and plant development, however, the regulation of FA metabolism is still poorly understood. To study the relevant regulatory network, fifty-eight FA biosynthesis genes including de novo synthases, desaturases and elongases were selected as 'guide genes' to construct the co-expression network. Calculation of the correlation between all Arabidopsis thaliana (L.) genes with each guide gene by Arabidopsis co-expression dating mining tools (ACT) identifies 797 candidate FA-correlated genes. Gene ontology (GO) analysis of these co-expressed genes showed they are tightly correlated to photosynthesis and carbohydrate metabolism, and function in many processes. Interestingly, 63 transcription factors (TFs) were identified as candidate FA biosynthesis regulators and 8 TF families are enriched. Two TF genes, CRC and AP1, both correlating with 8 FA guide genes, were further characterized. Analyses of the ap1 and crc mutant showed the altered total FA composition of mature seeds. The contents of palmitoleic acid, stearic acid, arachidic acid and eicosadienoic acid are decreased, whereas that of oleic acid is increased in ap1 and crc seeds, which is consistent with the qRT-PCR analysis revealing the suppressed expression of the corresponding guide genes. In addition, yeast one-hybrid analysis and electrophoretic mobility shift assay (EMSA) revealed that CRC can bind to the promoter regions of KCS7 and KCS15, indicating that CRC may directly regulate FA biosynthesis.Xinxin Han Linlin Yin Hongwei Xue 2012Journal of Integrative Plant Biology2012,54,7:3

20Unified modeling of the monotonic and cyclic behaviors of sand and clay显示文摘In this study, we aim to investigate a unified modeling method for the monotonic and cyclic behaviors of sand and clay. A simple double-yield-surface model, with plastic hardening modulus and dilatancy relation being dependent on density state unlike in existing approaches,is developed by considering the location of the critical state line. The model is used to simulate the drained and undrained tests of various sands and clays under monotonic and cyclic loadings.Prediction results are compared with experimental results, which show that the proposed approach is capable of modeling the monotonic and cyclic behaviors of sand and clay.Yinfu Jin Zhenyu Yin Dongmei Zhang Hongwei Huang 2015Acta Mechanica Solida Sinica2015,28,2:3
