1Insight-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

3Modified fertilization management of summer maize(Zea mays L.) in northern China improves grain yield and efficiency of nitrogen use显示文摘Improving the yield of maize grain per unit area is needed to meet the growing demand for it in China, where the availability of fertile land is very limited.Modified fertilization management and planting density are efficient methods for increasing crop yield.Field experiments were designed to investigate the influence of modified fertilization management and planting density on grain yield and nitrogen use efficiency of the popular maize variety Zhengdan 958, in four treatments including local farmer's practice(FP), high-yielding and high efficiency cultivation(HH), super high-yielding cultivation(SH), and the control(CK).Trials were conducted in three locations of the Huang-Huai-Hai Plain in northern China.Compared with FP, SH was clearly able to promote N absorption and dry matter accumulation in post-anthesis, and achieve high yield and N use efficiency by increasing planting density and postponing the supplementary application of fertilizers.However, with an increase in planting density, the demand of N increased along with grain yield.Due to the input of too much N fertilizer, the efficiency of N use in SH was low.Applying less total N, ameliorating cultivation and cropping management practices should be considered as priority strategies to augment production potential and finally achieve synchronization between high yield and high N efficiency in fertile soils.However, in situations where soil fertility is low, achieving high yield and high N use efficiency in maize will likely depend on increased planting density and appropriate application of supplementary fertilizers postpone to the grain-filling stage.CHENG Yi ZHAO Jie LIU Zhen-xiang HUO Zhi-jin LIU Peng DONG Shu-ting ZHANG Ji-wang ZHAO Bin 2015Journal of Integrative Agriculture2015,14,8:9

5A genetic linkage map of hexaploid naked oat constructed with SSR markers显示文摘Naked oat is a unique health food crop in China. Using 202 F2 individuals derived from a hybrid between the variety 578 and the landrace Sanfensan, we constructed a genetic linkage map consisting of 22 linkage groups covering 2070.50 c M and including 208 simple sequence repeat(SSR) markers. The minimum distance between adjacent markers was0.01 c M and the average was 9.95 c M. Each linkage group contained 2–22 markers. The largest linkage group covered 174.40 c M and the shortest one covered 36.80 c M, with an average of 94.11 c M. Thirty-six markers(17.3%) showing distorted segregation were distributed across linkage groups LG5 to LG22. This map complements published oat genetic maps and is applicable for quantitative trait locus analysis, gene cloning and molecular marker-assisted selection.Gaoyuan Song Pengjie Huo Bin Wu Zongwen Zhang 2015The Crop Journal2015,3,4:6
6High resolution range profile analysis based on multicarrier phase-coded waveforms of OFDM radar显示文摘Orthogonal frequency division multiplexing(OFDM) radar with multicarrier phase-coded waveforms has been recently introduced to achieve high range resolution.The conventional method for obtaining the high resolution range profile(HRRP) is based on matched filters.A method of synthesizing HRRP based on the fast Fourier transform(FFT) and decoding is proposed.The mathematical expressions of HRRP are derived by assuming an elementary scenario of point-scattering targets.Based on the characteristic of OFDM multicarrier signals,it mainly analyzes the influence on HRRP exerted by several factors,such as velocity compensation errors,the sampling frequency offset,and so on.The conclusions are significant for the design of the OFDM imaging radar.Finally,the simulation results demonstrate the validity of the conclusions.Kai Huo Bin Deng Yongxiang Liu Weidong Jiang Junjie Mao 2011Journal of Systems Engineering and Electronics2011,22,3:5
7Research gaps for three main tropical diseases in the People’s Republic of China显示文摘This scoping review analyzes the research gaps of three diseases:schistosomiasis japonica,malaria and echinococcosis.Based on available data in the P.R.China,we highlight the gaps between control capacity and prevalence levels,and between diagnostic/drug development and population need for treatment at different stages of the national control programme.After reviewing the literature from 848 original studies and consultations with experts in the field,the gaps were identified as follows.Firstly,the malaria research gaps include(i)deficiency of active testing in the public community and no appropriate technique to evaluate elimination,(ii)lack of sensitive diagnostic tools for asymptomatic patients,(iii)lack of safe drugs for mass administration.Secondly,gaps in research of schistosomiasis include(i)incongruent policy in the implementation of integrated control strategy for schistosomiasis,(ii)lack of effective tools for Oncomelania sp.snail control,(iii)lack of a more sensitive and cheaper diagnostic test for large population samples,(iv)lack of new drugs in addition to praziquantel.Thirdly,gaps in research of echinococcosis include(i)low capacity in field epidemiology studies,(ii)lack of sanitation improvement studies in epidemic areas,(iii)lack of a sensitivity test for early diagnosis,(iv)lack of more effective drugs for short-term treatment.We believe these three diseases can eventually be eliminated in China's Mainland if all the research gaps are abridged in a short period of time.Qi Zheng Samantha Vanderslott Bin Jiang Li-Li Xu Cong-Shan Liu Le-Le Huo Li-Ping Duan Ning-Bo Wu Shi-Zhu Li Zhi-Gui Xia Wei-Ping Wu Wei Hu Hao-Bing Zhang 2013Infectious Diseases of Poverty2013,2,1:5
8Monte-Carlo simulation of pinhole collimator of a small field of view gamma camera for small animal imaging显示文摘Needs in scintimammography applications,especially for small animal cardiac imaging,lead to develop a small field of view,high spatial resolution gamma camera with a pinhole collimator.However the ideal pinhole collimator must keep a compromise between spatial resolution and sensitivity.In order to design a pinhole collimator with an optimized sensitivity and spatial resolution,the spatial resolution and the geometric sensitivity response as a function of the source to collimator distance has been obtained by means of Monte-Carlo simulation for a small field of view gamma camera with a pinhole collimator of various-hole diameters.The results show that the camera with pinhole of 1 mm,1.5 mm and 2 mm diameter has respectively spatial resolution of 1.5 mm,2.25 mm and 3 mm and geometric sensitivity of 0.016%,0.022%and 0.036%,while the source to collimator distance is 3 cm.We chose the pinhole collimator with hole diameter size of 1.2 mm for our the gamma camera designed based on the trade-off between sensitivity and resolution.ZHU Jie MA Wenyan ZHU Yufeng MA Hongguang WU Yuelei HU Huasi ZHANG Boping HUO Yonggang LIU Silu JIAN Bin WANG Zhaomin 2009Nuclear Science and Techniques2009,20,1:4

11Safety and efficacy of meplazumab in healthy volunteers and COVID-19 patients: a randomized phase 1 and an exploratory phase 2 trial显示文摘Recent evidence suggests that CD147 serves as a novel receptor for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection.Blocking CD147 via anti-CD147 antibody could suppress the in vitro SARS-CoV-2 replication.Meplazumab is a humanized anti-CD147 IgG_(2) monoclonal antibody,which may effectively prevent SARS-CoV-2 infection in coronavirus disease 2019(COVID-19)patients.Here,we conducted a randomized,double-blinded,placebo-controlled phase 1 trial to evaluate the safety,tolerability,and pharmacokinetics of meplazumab in healthy subjects,and an open-labeled,concurrent controlled add-on exploratory phase 2 study to determine the efficacy in COVID-19 patients.In phase 1 study,59 subjects were enrolled and assigned to eight cohorts,and no serious treatment-emergent adverse event(TEAE)or TEAE grade≥3 was observed.The serum and peripheral blood Cmax and area under the curve showed non-linear pharmacokinetic characteristics.No obvious relation between the incidence or titer of positive anti-drug antibody and dosage was observed in each cohort.The biodistribution study indicated that meplazumab reached lung tissue and maintained>14 days stable with the lung tissue/cardiac blood-pool ratio ranging from 0.41 to 0.32.In the exploratory phase 2 study,17 COVID-19 patients were enrolled,and 11 hospitalized patients were involved as concurrent control.The meplazumab treatment significantly improved the discharged(P=0.005)and case severity(P=0.021),and reduced the time to virus negative(P=0.045)in comparison to the control group.These results show a sound safety and tolerance of meplazumab in healthy volunteers and suggest that meplazumab could accelerate the recovery of patients from COVID-19 pneumonia with a favorable safety profile.Huijie Bian Zhao-Hui Zheng Ding Wei Aidong Wen Zheng Zhang Jian-Qi Lian Wen-Zhen Kang Chun-Qiu Hao Jing Wang Rong-Hua Xie Ke Dong Jie-Lai Xia Jin-Lin Miao Wen Kang Guoquan Li Di Zhang Mingru Zhang Xiu-Xuan Sun Likun Ding Kui Zhang Junfeng Jia Jin Ding Zhiqin Li Yanyan Jia Lin-Na Liu Zhe Zhang Zhao-Wei Gao Hong Du Na Yao Qing Wang Ke Wang Jie-Jie Geng Bin Wang Ting Guo Ruo Chen Yu-Meng Zhu Li-Juan Wang Qian He Rui-Rui Yao Ying Shi Xiang-Min Yang Jian-Sheng Zhou Yi-Nan Ma Ya-Tao Wang Xue Liang Fei Huo Zhe Wang Yang Zhang Xu Yang Ye Zhang Lu-Hua Gao Ling Wang Xiao-Chun Chen Hao Tang Shuang-Shuang Liu Qing-Yi Wang Zhi-Nan Chen Ping Zhu 2021Signal Transduction and Targeted Therapy2021,6,6:2
12Slow-release praziquantel for dogs:presentation of a new formulation for echinococcosis control显示文摘Background:Echinococcosis is a serious,zoonotic,parasitic disease with worldwide distribution.According to a epidemiological survey in 2012 in China,there are 20,000 infected patients and more than 50 million people at the risk.As the dog is the main,definitive host,the Government of China encourages monthly praziquantel treatment of every dog.However,this is difficult to achieve in geographically challenging areas,such as the Tibetan plateau,where there are also many dogs without owners.To overcome these problems,we investigated the transmission blocking capacity of a slow-release formulation of praziquantel administered by subcutaneous injection.Methods:The impact of a slow-release preparation of two pharmacokinetically stereoselective praziquantel enantiomers,i.e.,R-(−)-praziquantel(R-PZQ)and S-(+)-praziquantel(S-PZQ)absorbed into a biodegradable polymer was studied in beagle dogs(N=6).The preparation was given by subcutaneous injection using a single dose of 100 mg/kg.Chiral-selective,high-performance liquid chromatography(HPLC)and high-resolution mass spectrometry(HRMS)were applied to measure the praziquantel enantiomers in the plasma of the dogs.The lower limit for estimating plasma concentrations accurately for R-PZQ was 4 ng/ml and for S-PZQ 20 ng/ml.The pharmacokinetic parameters were calculated by a noncompartmental analysis model using Drug Analyze System(DAS)software 2.0.The SPSS 19.0 software was used for statistical analysis,and the statistical comparison between enantiomers was assessed using the two-tailed t-test.Results:Two hours after administration,peak concentrations of R-PZQ and S-PZQ:321±26 and 719±263 ng/ml,respectively,were achieved.After 180 days,the average plasma concentration of R-PZQ in the six dogs had decreased to 13 ng/ml.The average concentration value of S-PZQ was higher than that of R-PZQ in the first 90-day period but fell afterwards and could not be accurately estimated when dropping below 20 ng/ml(the lower methodological limit for this enantiomer).Taking all the dogs into account,the average maximum concentration(Cmax)of S-PZQ in plasma over the first 3 months was higher than that of R-PZQ by 114.0%(P<0.05),while the average mean retention time(MRT)of R-PZQ in plasma was higher than that of S-PZQ by 96.3%(P<0.05).Conclusions:Praziquantel given as an in situ slow-release formulation by subcutaneous injection resulted in concentrations of the active principle in beagle dogs,which should be capable of resisting new Echinococcus infections for at least 6 months.The new formulation of praziquantel represents a potential,alternative way of presenting medication against tapeworm infections in dogs.Bin Jiang Xiao-Nong Zhou Hao-Bing Zhang Yi Tao Le-Le Huo Ni Liu 2017Infectious Diseases of Poverty2017,6,1:2
13Strength Analysis on Brace Structure for Semi-Submersible in Consideration of Wave Slamming显示文摘Slamming on bracings of column stabilized units shall be considered as a possible limiting criterion under transit condition based on the requirements in DNV-OS-C103. However, the wave slamming loads under survival condition were ignored for the strength analysis of the brace structures in many semi-submersible projects. In this paper, a method of strength analysis of brace structure is proposed based on the reconstruction and extrapolation of numerical model. The full-scale mooring system, the wind, wave and current loads can be considered simultaneously. Firstly,the model tests of the semi-submersible platform in wind tunnel and wave tanker have been carried out. Secondly,the numerical models of the platform are reconstructed and extrapolated based on the results of model tests. Then, a nonlinear numerical analysis has been conducted to study the wave slamming load on brace in semi-submersible platform through the reconstructed and extrapolated numerical model. For the randomness of wave load, ten subcases under each condition have been carried out. The value of the 90% Gumble distribution values of the ten subcases are used. Finally, the strength on brace structure has been analyzed considering the wave slamming. The wave slamming loads have been compared between the survival condition and transit condition with the method. The results indicate that wave slamming under survival condition is more critical than that under transit condition.Meanwhile, the wave slamming is significant to the structural strength of the brace. It should be overall considered in the strength analysis of the brace structure.HUO Fa-li YAO Zhi ZHANG Jian WANG Jun-wei DONG Bin 2018China Ocean Engineering2018,32,5:2
14Distribution of High-sensitivity C-reactive Protein Status in an Urban Population in China显示文摘Objectives To evaluate the distribution by age and sex of serum high-sensitivity C-reactive protein(hsCRP)in an urban Chinese population and to provide a profile prediction for the risk of bacterial infection,inflammatory diseases,or tissue damages in the body.Methods Serum hsCRP was determined using the Roche Tina-quant immuno-turbidimetric assay on a Hitachi 7600–010 automatic biochemical analyzer(Roche Diagnostics)in 1,572 males and 1,800 females,including 78 pregnant women,who were derived from the National Health and Nutrition Survey in2010–2012.Results The average hsCRP concentration in urban China was 0.68 mg/L for males and 0.65 mg/L for females.Significant differences in hsCRP were found among different age groups(P<0.05).Monitoring results showed no significant differences among the 6–11,45–59,and≥60-year-old groups in the comparison of hsCRP between males and females in large cities.However,hsCRP concentration was significantly higher in men aged 12–17 and 18–44 years than in women.Conclusion The distribution of the hsCRP status of residents in large cities in China was influenced by age and gender,and the hsCRP levels of both sexes increased gradually with age.In addition,hsCRP concentration was higher in healthy pregnant women than in non-pregnant women.Basing on our results,we recommend that this parameter be included in future national and international screening for early detection of various illnesses.TANG Yan Bin HUO Jun Sheng HUANG Jian LI Hong PIAO Jian Hua SUN Jing WANG Li Juan 2020Biomedical and Environmental Sciences2020,33,6:2
15Application and Characteristic Analysis of the Moist Singular Vector in GRAPES-GEPS显示文摘The singular vector(SV)initial perturbation method can capture the fastest-growing initial perturbation in a tangent linear model(TLM).Based on the global tangent linear and adjoint model of GRAPES-GEPS(Global/Regional Assimilation and Prediction System-Global Ensemble Prediction System),some experiments were carried out to analyze the structure of the moist SVs from the perspectives of the energy norm,energy spectrum,and vertical structure.The conclusions are as follows:The evolution of the SVs is synchronous with that of the atmospheric circulation,which is flowdependent.The moist and dry SVs are located in unstable regions at mid-to-high latitudes,but the moist SVs are wider,can contain more small-and medium-scale information,and have more energy than the dry SVs.From the energy spectrum analysis,the energy growth caused by the moist SVs is reflected in the relatively small-scale weather system.In addition,moist SVs can generate perturbations associated with large-scale condensation and precipitation,which is not true for dry SVs.For the ensemble forecasts,the average anomaly correlation coefficient of large-scale circulation is better for the forecast based on moist SVs in the Northern Hemisphere,and the low-level variables forecasted by the moist SVs are also improved,especially in the first 72 h.In addition,the moist SVs respond better to short-term precipitation according to statistical precipitation scores based on 10 cases.The inclusion of the large-scale condensation process in the calculation of SVs can improve the short-term weather prediction effectively.Jing WANG Bin WANG Juanjuan LIU Yongzhu LIU Jing CHEN Zhenhua HUO 2020Advances in Atmospheric Sciences2020,37,11:2

19Bone infection site targeting nanoparticle-antibiotics delivery vehicle to enhance treatment efficacy of orthopedic implant related infection显示文摘Orthopedic implants account for 99%of orthopedic surgeries,however,orthopedic implant-related infection is one of the most serious complications owing to the potential for limb-threatening sequelae and mortality.Current antibiotic treatments still lack the capacity to target bone infection sites,thereby resulting in unsatisfactory therapeutic effects.Here,the bone infection site targeting efficacy of D6 and UBI29-41 peptides was investigated,and bone-and-bacteria dual-targeted nanoparticles(NPs)with D6 and UBI29-41 peptides were first fabricated to target bone infection site and control the release of vancomycin in bone infection site.The results of this study demonstrated that the bone-and-bacteria dual-targeted mesoporous silica NPs exhibit excellent bone and bacteria targeting efficacy,excellent biocompatibility and effective antibacterial properties in vitro.Furthermore,in a rat model of orthopedic implant-related infection with methicillin-resistant Staphylococcus aureus,the growth of bacteria was evidently inhibited without cytotoxicity,thus realizing the early treatment of implant-related infection.Hence,the bone-and-bacteria dual-targeted molecule-modified NPs may target bacteria-infected bone sites and act as ideal candidates for the therapy of orthopedic implant-related infections.Bin’en Nie Shicheng Huo Xinhua Qu Jingjing Guo Xi Liu Qimin Hong You Wang Jianping Yang Bing Yue 2022Bioactive Materials2022,7,10:2
20Growth and feeding habits of invasive Pseudorasbora parva in the Chabalang Wetland(Lhasa,China) and its trophic impacts on native fish显示文摘In recent years, fish invasion has become one of the main reasons for the decline of native fish stocks. Pseudorasbora parva is considered one of the major invasive species worldwide. The present study investigated the fish resources of the Chabalang Wetland (Lhasa, Tibet) during diff erent seasons in 2009 and 2013. Four hundred and twelve individuals were subsampled to estimate age, growth, and feeding habit of P . parva . Furthermore, food relationships between P . parva and the native Schizothoracinae fish were also examined. The results revealed a significant shift in species composition and community structure characterized by the disappearance of native fish and outbreak of non-native fish. The percentage of nonnative P . parva in the fish collections significantly increased from 33.64% in 2009 to 64.08% in 2013. The standard length (SL) ranged from 22.00 to 78.71 mm, and their age was 1–5 a. The von Bertalanff y function was used to model the observed length-at-age data as L t =112.19(1–e^-0.1495 ( t +0.8012)) for females and as L t =123.12 (1–e^-0.1500 ( t +0.7132)) for males. The results indicated that P . parva in Tibet has lower growth and mortality rates compared with that from the native ranges. Ninety-seven prey taxa belonging to 9 prey categories were identified in the gut of 38 P . parva . P . parva can be considered a generalized and opportunistic predator, competing with the native fish, especially Schizothorax o’connori , Schizopygopsis younghusbandi younghusbandi , and Ptychobarbus dipogon , for Bacillariophyta and Chironomid larvae. This is an important reason for the decline in native fish population.DING Huiping GU Xiaohong ZHANG Zhiming HUO Bin LI Dapeng XIE Congxin 2019Journal of Oceanology and Limnology2019,37,2:2
