1Simulation of the Interaction between Driver and Seat显示文摘Test is one of methods to acquire human-seat pressure distribution in driving,with the deficiency of being uneasy to obtain the stress information of soft tissue inside human body and the sheer force of interface between human and seat,which can be obtained by simulation.But current simulation method focuses mainly on calculation itself other than combining it with posture prediction and cab packaging parameters,which cause it difficult to acquire accurate pressure calculation results without accurate posture of human body,and make it almost meaningless to design optimization.Therefore,a human body geometric model with posture change capability is built and linked up with Cascade Prediction Model(CPM),which takes cab packaging parameters as inputs.A detailed finite element model of driver human body is constructed and used to conduct the driver-seat interaction simulation between human body and seat.Good accordance of pressure distribution is observed between simulation and test,which validates the simulation.In addition to the distribution pattern,curves on key sections are used to analyze the pressure and shear stress on the seat surface,as well as soft tissue stress inside human body.The simulation shows that the maximum stress of buttocks locates under the ischial tuberosity,and the maximum stress of trunk occurs near the scapula posterior and the lower waist.These are the places where fatigue usually occurs.The maximum pressure of seat appears at the driver-seat contact area corresponding to the driver’s maximum skin tissue stress.In order to guide the seat design and cab packaging and study the influence of posture to pressure distribution,finite element models for different levels of cab packaging parameters are created by using CPM.The pressure distributions are calculated and their tendencies varying with cab packaging parameters are obtained.The method presented provides a new way to accurately simulate the interaction between driver human body and seat,and to guide the seat design and cab packaging so as to improve seating comfort.DU Xiaoming REN Jindong SANG Chunlei LI Lemeng 2013Chinese Journal of Mechanical Engineering2013,26,6:14
2Insight-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
3Nanopore-based Fourth-generation DNA Sequencing Technology显示文摘Nanopore-based sequencers, as the fourth-generation DNA sequencing technology, have the potential to quickly and reliably sequence the entire human genome for less than $1000, and possibly for even less than $100. The single-molecule techniques used by this technology allow us to further study the interaction between DNA and protein, as well as between protein and protein.Nanopore analysis opens a new door to molecular biology investigation at the single-molecule scale.In this article, we have reviewed academic achievements in nanopore technology from the past as well as the latest advances, including both biological and solid-state nanopores, and discussed their recent and potential applications.Yanxiao Feng Yuechuan Zhang Cuifeng Ying Deqiang Wang Chunlei Du 2015Genomics, Proteomics & Bioinformatics2015,13,1:11

5The Medium Energy X-ray telescope (ME) onboard the Insight-HXMT astronomy satellite显示文摘The Medium Energy X-ray telescope(ME) is one of the three main telescopes on board the Insight hard X-ray modulation telescope(Insight-HXMT) astronomy satellite. ME contains 1728 pixels of Si-PIN detectors sensitive in 5-30 ke V with a total geometrical area of 952 cm^2. The application specific integrated circuit(ASIC) chip, VA32TA6, is used to achieve low power consumption and low readout noise. The collimators define three kinds of field of views(FOVs) for the telescope, 1°×4°, 4°×4°,and blocked ones. Combination of such FOVs can be used to estimate the in-orbit X-ray and particle background components.The energy resolution of ME is ~3 ke V at 17.8 ke V(FWHM) and the time resolution is 255 μs. In this paper, we introduce the design and performance of ME.XueLei Cao WeiChun Jiang Bin Meng WanChang Zhang Tao Luo Sheng Yang ChunLei Zhang YuDong Gu Liang Sun XiaoJing Liu JiaWei Yang Xian Li Ying Tan ShaoZhen Liu YuanYuan Du FangJun Lu YuPeng Xu Ju Guan ShuangNan Zhang HuanYu Wang TiPei Li ChengMo Zhang XiangYang Wen JinLu Qu LiMing Song XiaoBo Li MingYu Ge YuPeng Zhou ShaoLin Xiong Shu Zhang YongJie Zhang ZeHao Cheng Fei Zhang MaoShun Li XiaoHua Liang Min Gao EnBo Yang XiaoHang Liu HongWei Liu YiJung Yang Fan Zhang 2020Science China(Physics,Mechanics & Astronomy)2020,63,4:5
6Overview to the Hard X-ray Modulation Telescope (Insight-HXMT) Satellite显示文摘As China’s first X-ray astronomical satellite, the Hard X-ray Modulation Telescope (HXMT), which was dubbed as Insight-HXMT after the launch on June 15, 2017, is a wide-band(1-250 ke V) slat-collimator-based X-ray astronomy satellite with the capability of all-sky monitoring in 0.2-3 Me V.

8Clinical factors associated with composition of lung microbiota and important taxa predicting clinical prognosis in patients with severe community-acquired pneumonia显示文摘Few studies have described the key features and prognostic roles of lung microbiota in patients with severe community-acquired pneumonia(SCAP).We prospectively enrolled consecutive SCAP patients admitted to ICU.Bronchoscopy was performed at bedside within 48 h of ICU admission,and 16S rRNA gene sequencing was applied to the collected bronchoalveolar lavage fluid.The primary outcome was clinical improvements defined as a decrease of 2 categories and above on a 7-category ordinal scale within 14 days following bronchoscopy.Sixty-seven patients were included.Multivariable permutational multivariate analysis of variance found that positive bacteria lab test results had the strongest independent association with lung microbiota(R2=0.033;P=0.018),followed by acute kidney injury(AKI;R2=0.032;P=0.011)and plasma MIP-1βlevel(R2=0.027;P=0.044).Random forest identified that the families Prevotellaceae,Moraxellaceae,and Staphylococcaceae were the biomarkers related to the positive bacteria lab test results.Multivariable Cox regression showed that the increase inα-diversity and the abundance of the families Prevotellaceae and Actinomycetaceae were associated with clinical improvements.The positive bacteria lab test results,AKI,and plasma MIP-1βlevel were associated with patients’lung microbiota composition on ICU admission.The families Prevotellaceae and Actinomycetaceae on admission predicted clinical improvements.Sisi Du Xiaojing Wu Binbin Li Yimin Wang Lianhan Shang Xu Huang Yudi Xia Donghao Yu Naicong Lu Zhibo Liu Chunlei Wang Xinmeng Liu Zhujia Xiong Xiaohui Zou Binghuai Lu Yingmei Liu Qingyuan Zhan Bin Cao 2022Frontiers of Medicine2022,16,3:2
