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
2Dietary seaweed-derived polysaccharides improve growth performance of weaned pigs through maintaining intestinal barrier function and modulating gut microbial populations显示文摘Background:Seaweed-derived polysaccharides(SDP)represent an attractive source of prebiotic nutraceuticals for the food and animal husbandry industry.However,the mechanism by which SDP from Enteromorpha mediates pig growth are not fully understood.This study aimed to investigate how SDP supplementation influences the growth performance and intestinal health in weaned pigs.Results:In Exp.1,240 weaned pigs were randomly assigned to four dietary treatments and fed with a basal diet or a basal diet containing 200,400 or 800 mg/kg SDP,respectively,in a 21-day trial.Pigs on the 400 or 800 mg/kg SDP-supplemented group had greater ADG and lower F/G ratio than those on the control group(P<0.05).In Exp.2,20 male weaned pigs were randomly assigned to two treatments and fed with a basal diet(CON group)or a basal diet supplemented with 400 mg/kg SDP(the optimum does from Exp.1),in a 21-day trial.Pigs fed the SDP diet had greater ADG,the concentrations of serum IL-6 and TNF-αand the activities of glutathione peroxidase,superoxide dismutase and catalase(P<0.05),and lower F/G,diarrhea rate,as well as serum D-lactate concentrations and diamine oxidase activity(P<0.05).Moreover,dietary SDP supplementation enhanced secretory immunoglobulin A content,villus height and villous height:crypt depth ratio in small intestine,as well as the lactase and maltase activities in jejunum mucosa(P<0.05).SDP supplementation elevated the mRNA levels of inflammatory responserelated genes(IL-6,TNF-α,TLR4,TLR6 and MyD88),and the mRNA and protein levels of ZO-1,claudin-1 and occludin in jejunum mucosa(P<0.05).Importantly,SDP not only increased the Lactobacillus population but also reduced the Escherichia coli population in cecum(P<0.05).Furthermore,SDP increased acetic acid and butyric acid concentrations in cecum(P<0.05).Conclusions:These results not only suggest a beneficial effect of SDP on growth performance and intestinal barrier functions,but also offer potential mechanisms behind SDP-facilitated intestinal health in weaned pigs.Tiande Zou Jin Yang Xiaobo Guo Qin He Zirui Wang Jinming You 2021Journal of Animal Science and Biotechnology2021,12,3:10
3Graphitic Carbon Quantum Dots Modified Nickel Cobalt Sulfide as Cathode Materials for Alkaline Aqueous Batteries显示文摘Carbon quantum dots(CQDs)as a new class of emerging materials have gradually drawn researchers’concern in recent years.In this work,the graphitic CQDs are prepared through a scalable approach,achieving a high yield with more than 50%.The obtained CQDs are further used as structure-directing and conductive agents to synthesize novel N,S-CQDs/NiCo2S4 composite cathode materials,manifesting the enhanced electrochemical properties resulted from the synergistic effect of highly conductive N,S-codoped CQDs offering fast electronic transport and unique micro-/nanostructured NiCo2S4 microspheres with Faradaic redox characteristic contributing large capacity.Moreover,the nitrogen-doped reduced graphene oxide(N-rGO)/Fe2O3 composite anode materials exhibit ultrahigh specific capacity as well as significantly improved rate property and cycle performance originating from the high-capacity prism-like Fe2O3 hexahedrons tightly wrapped by highly conductive N-rGO.A novel alkaline aqueous battery assembled by these materials displays a specific energy(50.2 Wh kg^−1),ultrahigh specific power(9.7 kW kg^−1)and excellent cycling performance with 91.5%of capacity retention at 3 A g^−1 for 5000 cycles.The present research offers a valuable guidance for the exploitation of advanced energy storage devices by the rational design and selection of battery/capacitive composite materials.Yirong Zhu Jingying Li Xiaoru Yun Ganggang Zhao Peng Ge Guoqiang Zou Yong Liu Hongshuai Hou Xiaobo Ji 2020Nano-Micro Letters2020,12,2:10
4Identification and characterization of rice blast resistance gene Pid4 by a combination of transcriptomic profiling and genome analysis显示文摘Map-based cloning of plant disease resistance (R) genes is time-consuming. Here, we reported the isolation of blast R gene Pid4 using comparative transcriptomic profiling and genome-wide sequence analysis. Pid4 encodes a coiled-coil nucleotide-binding site leucine-rich repeat(CC-NBS-LRR) protein and is constitutively expressed at diverse developmental stages in the rice variety Digu. The Pid4 protein is localized in both the nucleus and cytoplasm. Introduction of Pid4 into susceptible rice cultivars confers race-specific resistance to leaf and neck blast. Amino acid sequence comparison and blast resistance spectrum tests showed that Pid4 is a novel R gene, different from the previously reported R genes located in the same gene cluster. A Pid4 Indel marker was developed to facilitate the identification of Pid4 in different rice varieties. We demonstrated that a plant R gene can be quickly isolated using transcriptomic profiling coupled with genome-wide sequence analysis.Zhixiong Chen Wen Zhao Xiaobo Zhu Chengdong Zou Junjie Yin Mawsheng Chern Xiaogang Zhou Heng Ying Xin Jiang Yongzhen Li Haicheng Liao Mengping Cheng Weitao Li Min He Jing Wang Jichun Wang Bingtian Ma Jirui Wang Shigui Li Lihuang Zhu Xuewei Chen 2018Journal of Genetics and Genomics2018,45,12:7
5In vitro and in vivo biodegradation and biocompatibility of an MMT/BSA composite coating upon magnesium alloy AZ31显示文摘The performance of biodegradable magnesium alloy requires special attention to rapid degradation and poor biocompatibility, which can cause the implant to fail. Here, a sodium montmorillonite(MMT)/bovine serum albumin(BSA) composite coating was prepared upon magnesium alloy AZ31 via hydrothermal synthesis, followed by dip coating. We evaluated the surface characterization and corrosion behavior in vitro, and the biocompatibility in vitro and in vivo. Biodegradation progress of the MMT-BSA coated Mg pieces was examined through hydrogen evolution, immersion tests, and electrochemical measurements in Hank’s solution. In vitro biocompatibility studies were evaluated via hemolysis tests, dynamic cruor time tests, platelet adhesion, MTT testing and live-dead stain of osteoblast cells(MC3 T3-E1). It was found that the MMT-BSA coating had good corrosion resistance and a marked improvement in biocompatibility in comparison to bare Mg alloy AZ31. in vivo studies were carried out in rat model and the degradation was characterized by computed tomography scans. Results revealed that the MMT-BSA coated Mg alloy AZ31 implants maintained their structural integrity and slight degradation after 120 d of post-implantation. A100% survival rate for the rats was observed with no obvious toxic damages on the organs and tissues.Additionally, we proposed a sound coating formation mechanism. Considering the good corrosion protection and biocompatibility, the MMT-BSA coated Mg alloy AZ31 is a promising candidate material for biomedical implants.Jian Wang Lanyue Cui Yande Ren Yuhong Zou Jinlong Ma Chengjian Wang Zhongyin Zheng Xiaobo Chen Rongchang Zeng Yufeng Zheng 2020Journal of Materials Science & Technology2020,47,12:7

7NAD+metabolism:pathophysiologic mechanisms and therapeutic potential显示文摘Nicotinamide adenine dinucleotide(NAD^(+))and its metabolites function as critical regulators to maintain physiologic processes,enabling the plastic cells to adapt to environmental changes including nutrient perturbation,genotoxic factors,circadian disorder,infection,inflammation and xenobiotics.These effects are mainly achieved by the driving effect of NAD^(+)on metabolic pathways as enzyme cofactors transferring hydrogen in oxidation-reduction reactions.Besides,multiple NAD^(+)-dependent enzymes are involved in physiology either by post-synthesis chemical modification of DNA,RNA and proteins,or releasing second messenger cyclic ADPribose(cADPR)and NAADP^(+).Prolonged disequilibrium of NAD^(+)metabolism disturbs the physiological functions,resulting in diseases including metabolic diseases,cancer,aging and neurodegeneration disorder.In this review,we summarize recent advances in our understanding of the molecular mechanisms of NAD^(+)-regulated physiological responses to stresses,the contribution of NAD^(+)deficiency to various diseases via manipulating cellular communication networks and the potential new avenues for therapeutic intervention.Na Xie Lu Zhang Wei Gao Canhua Huang Peter Ernst Huber Xiaobo Zhou Changlong Li Guobo Shen Bingwen Zou 2020Signal Transduction and Targeted Therapy2020,5,1:5

9Insights into Enhanced Capacitive Behavior of Carbon Cathode for Lithium Ion Capacitors: The Coupling of Pore Size and Graphitization Engineering显示文摘The lack of methods to modulate intrinsic textures of carbon cathode has seriously hindered the revelation of in-depth relationship between inherent natures and capacitive behaviors,limiting the advancement of lithium ion capacitors(LICs).Here,an orientateddesigned pore size distribution(range from 0.5 to 200 nm)and graphitization engineering strategy of carbon materials through regulating molar ratios of Zn/Co ions has been proposed,which provides an effective platform to deeply evaluate the capacitive behaviors of carbon cathode.Significantly,after the systematical analysis cooperating with experimental result and density functional theory calculation,it is uncovered that the size of solvated PF6-ion is about 1.5 nm.Moreover,the capacitive behaviors of carbon cathode could be enhanced attributed to the controlled pore size of 1.5-3 nm.Triggered with synergistic effect of graphitization and appropriate pore size distribution,optimized carbon cathode(Zn90Co10-APC)displays excellent capacitive performances with a reversible specific capacity of^50 mAh g-1at a current density of 5 A g-1.Furthermore,the assembly pre-lithiated graphite(PLG)//Zn90Co10-APC LIC could deliver a large energy density of 108 Wh kg-1 and a high power density of 150,000 W kg-1 as well as excellent long-term ability with 10,000 cycles.This elaborate work might shed light on the intensive understanding of the improved capacitive behavior in LiPF6 electrolyte and provide a feasible principle for elaborate fabrication of carbon cathodes for LIC systems.Kangyu Zou Peng Cai Baowei Wang Cheng Liu Jiayang Li Tianyun Qiu Guoqiang Zou Hongshuai Hou Xiaobo Ji 2020Nano-Micro Letters2020,12,9:4

11Real-time grain breakage sensing for rice combine harvesters using machine vision technology显示文摘Breakage rate is one of the most important indicators to evaluate the harvesting performance of a combine harvester.It is affected by operating parameters of a combine such as feeding rate,the peripheral speed of the threshing cylinder and concave clearance,and shows complex non-linear law.Real-time acquisition of the breakage rate is an effective way to find the correlation of them.In addition,real-time monitoring of the breakage rate can help the driver optimize and adjust the operating parameters of a combine harvester to avoid the breakage rate exceeding the standard.In this study,a real-time monitoring method for the grain breakage rate of the rice combine harvester based on machine vision was proposed.The structure of the sampling device was designed to obtain rice kernel images of high quality in the harvesting process.According to the working characteristics of the combine,the illumination and installation of the light source were optimized,and the lateral lighting system was constructed.A two-step method of“color training-verification”was applied to identify the whole and broken kernels.In the first step,the local threshold algorithm was used to get the edge of kernel particles in a few training images with binary transformation,extract the color spectrum of each particle in color-space HSL and output the recognition model file.The second step was to verify the recognition accuracy and the breakage rate monitoring accuracy through grabbing and processing images in the laboratory.The experiments of about 2300 particles showed that the recognition accuracy of 96%was attained,and the monitoring values of breakage rate and the true artificial monitoring values had good trend consistency.The monitoring device of grain breakage rate based on machine vision can provide technical supports for the intellectualization of combine harvester.Jin Chen Yi Lian Rong Zou Shuai Zhang Xiaobo Ning Mengna Han 2020International Journal of Agricultural and Biological Engineering2020,13,3:3
12结外鼻型NK/T细胞淋巴瘤的流行病学调查(英文)显示文摘Extranodal natural killer(NK)/T-cell lymphoma,nasal type(ENKTCL) is a rarely kind of non-Hodgkin lymphoma(NHL).It is much more frequent in Asian and Latin American countries than other part of the world.It typically affects nasal cavity.In China,one of its endemically places,ENKTCL accounts for 74%-96% of nasal NHL.Patients with ENKTCL usually show a highly aggressive clinical course,and its etiology is unclear.However,it is already proved that ENKTCL is associated with Epstein-Barr virus(EBV) infection,regardless patients',ethnicity and areas.Some studies show that the risk will increase among several occupations,such as farmer,who are frequently exposure to pesticides and chemical solvent and risk can be cut down if taking some protective measures.Yao Liao Xiaobo Du Qingfeng Zou 2012The Chinese-German Journal of Clinical Oncology2012,11,5:3
13Metabolic regulation of T cell development by Sinl-mTORC2 is mediated by pyruvate kinase M2显示文摘Glucose metabolism plays a key role in thymocyte development. The mammalian target of rapamycin complex 2 (mT0RC2) is a critical regulator of cell growth and metabolism, but its role in early thymocyte development and metabolism has not been fully studied. We show here that genetic ablation of Sinl, an essential component of mTORC2, in T lineage cells results in severely impaired thymocyte development at the CD4^- CD8^- double negative (DN) stages but not at the CD4^+ CD8^+ double positive (DP) or later stages. Notably, Sinl-deficient DN thymocytes show markedly reduced proliferation and glycolysis.Importantly, we discover that the M2 isoform of pyruvate kinase (PKM2) is a novel and crucial Sinl effector in promoting DN thymocyte development and metabolism. At the molecular level, we show that Sinl-mTORC2 controls PKM2 expression through an AKT-dependent PPAR-y nuclear translocation. Together, our study unravels a novel mTORC2-PPAR-γ-PKM2 pathway in immune-metabolic regulation of early thymocyte development.Xinxing Ouyang Yuheng Han Guojun Qu Man Li Ningbo Wu Hongzhi Liu Omotooke Arojo Hongxiang Sun Xiaobo Liu Dou Liu Lei Chen Qiang Zou Bing Su 2019Journal of Molecular Cell Biology2019,11,2:3
14Rapid qualitative and quantitative analysis of strong aroma base liquor based on SPME-MS combined with chemometrics显示文摘To objectively classify and evaluate the strong aroma base liquors(SABLs)of different grades,solid-phase microextraction-mass spectrometry(SPME-MS)combined with chemometrics were used.Results showed that SPME-MS combined with a back-propagation artificial neural network(BPANN)method yielded almost the same recognition performance compared to linear discriminant analysis(LDA)in distinguishing different grades of SABL,with 84%recognition rate for the test set.Partial least squares(PLS),successive projection algorithm partial least squares(SPA-PLS)model,and competitive adaptive reweighed samplingpartial least squares(CARS-PLS)were established for the prediction of the four esters in the SABL.CARS-PLS model showed a greater advantage in the quantitative analysis of ethyl acetate,ethyl butyrate,ethyl caproate,and ethyl lactate.These results corroborated the hypothesis that SPME-MS combined with chemometrics can effectively achieve an accurate determination of different grades of SABL and prediction performance of esters.Zongbao Sun Junkui Li Jianfeng Wu Xiaobo Zou Chi-Tang Ho Liming Liang Xiaojing Yan Xuan Zhou 2021Food Science and Human Wellness2021,10,3:3
15Crack-free single-crystalline Co-free Ni-rich LiNi_(0.95)Mn_(0.05)O_(2) layered cathode显示文摘The rapid growth in global electric vehicles(EVs)sales has promoted the development of Co-free,Ni-rich layered cathodes for state-of-the-art high energy-density,inexpensive lithium-ion batteries(LIBs).However,progress in their commercial use has been seriously hampered by exasperating performance deterioration and safety concerns.Herein,a robust single-crystalline,Co-free,Ni-rich LiNi_(0.95)Mn_(0.05)O_(2)(SC-NM95)cathode is successfully designed using a molten salt-assisted method,and it exhibits better structural stability and cycling durability than those of polycrystalline LiNi_(0.95)Mn_(0.05)O_(2) (PC-NM95).Notably,the SC-NM95 cathode achieves a high discharge capacity of 218.2 mAh g^(-1),together with a high energy density of 837.3 Wh kg^(-1) at 0.1 C,mainly due to abundant Ni^(2+)/Ni^(3+) redox.It also presents an outstanding capacity retention(84.4%)after 200 cycles at 1 C,because its integrated single-crystalline structure effectively inhibits particle microcracking and surface phase transformation.In contrast,the PC-NM95 cathode suffers from rapid capacity fading owing to the nucleation and propagation of intergranular microcracking during cycling,facilitating aggravated parasitic reactions and rocksalt phase accumulation.This work provides a fundamental strategy for designing high-performance singlecrystalline,Co-free,Ni-rich cathode materials and also represents an important breakthrough in developing high-safe,low-cost,and high-energy LIBs.Lianshan Ni Ruiting Guo Susu Fang Jun Chen Jinqiang Gao Yu Mei Shu Zhang Wentao Deng Guoqiang Zou Hongshuai Hou Xiaobo Ji 2022eScience2022,2,1:2
16Recent advances of composite electrolytes for solid-state Li batteries显示文摘All-solid-state lithium batteries(ASSLBs)are recognized as high energy density batteries system without safety issues within the next generation of batteries.The development of solid electrolytes is the crucial step of ASSLBs.The composite electrolyte has stable physical and electrochemical characteristics,and its comprehensive performance surpasses the individual solid electrolyte,bringing unique vitality to the solid electrolyte.However,their intrinsic weakness limits the development of composite electrolytes.In this review,we provide a comprehensive and in-depth understanding of the challenges and opportunities of composite electrolytes,with special focus on mechanisms of ion transport,nanostructure design towards high ionic conductivity,interfacial issues within electrolytes and electrodes.Furthermore,future development is prospected,which can shed light on researchers in this field and accelerate the industrial production of composite electrolytes.Laiqiang Xu Jiayang Li Honglei Shuai Zheng Luo Baowei Wang Susu Fang Guoqiang Zou Hongshuai Hou Hongjian Peng Xiaobo Ji 2022Journal of Energy Chemistry2022,31,4:2
17Extraction optimization of insecticidal compounds from Lysurus mokusin by response surface methodology显示文摘We optimized the extraction process of Lysurus mokusin(L.)Fr.insecticidal compound(LMIC)using response surface methodology with ultrasonic extraction(UE).The surface morphologies of maceration extract(ME)and UE residues were compared by scanning electron microscopy,and then the activity of LMIC on Lymantria dispar(Asian gypsy moths)larvae was determined.Results showed that the optimal condition of UE was followed by 80 min of extraction time,60%of ethanol concentration and 80 mL g^-1 of liquid–solid ratio.The surface morphologies of UE residue were looser and rougher than ME residue.The corrected mortalities of LMIC on L.dispar larvae was 59.77%.This result indicated that L.mokusin was a good candidate as pesticide for pest management.Liannan Lin Jing Yang Guocai Zhang Xiaobo Zhang Chuanshan Zou Tingyu Wang Jianyong Zeng 2020Journal of Forestry Research2020,31,5:2
18A 12-bit 250-MS/s Charge-Domain Pipelined Analog-to-Digital Converter with Feed-Forward Common-Mode Charge Control显示文摘A feed-forward Common-Mode(CM) charge control circuit for a high-speed Charge-Domain(CD)pipelined Analog-to-Digital Converter(ADC) is presented herein.This study aims at solving the problem whereby the precision of CD pipelined ADCs is restricted by the variation in input CM charge,which can compensate for CM charge errors caused by a variation in CM charge input in real time.Based on the feed-forward CM charge control circuit,a 12-bit 250-MS/s CD pipelined ADC is designed and realized using a 1 P6 M 0.18-μm CMOS process.The ADC achieved a Spurious Free Dynamic Range(SFDR) of 78.1 d B and a Signal-to-Noise-and-Distortion Ratio(SNDR) of 64.6 d B for a 20.1-MHz input:a SFDR of 74.9 d B and SNDR of 62.0 d B were achieved for a 239.9-MHz input at full sampling rate.The variation in signal-to-noise ratio was less than 3 d B over a 0–1.2 V input CM voltage range.The power consumption of the prototype ADC is only 85 m W at 1.8 V supply,and it occupies an active die area of 2.24 mm^2.Zongguang Yu Xiaobo Su Zhenhai Chen Jiaxuan Zou Jinghe Wei Hong Zhang Yan Xue 2018Tsinghua Science and Technology2018,23,1:2
