| 1 | Insight-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 | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 2 | The High Energy X-ray telescope (HE) onboard the Insight-HXMT astronomy satellite显示文摘The Insight-Hard X-ray Modulation Telescope(Insight-HXMT) is a broadband X-ray and γ-ray(1-3000 ke V) astronomy satellite. One of its three main telescopes is the High Energy X-ray telescope(HE). The main detector plane of HE comprises 18 Na I(Tl)/Cs I(Na) phoswich detectors, where Na I(Tl) is used as the primary detector to measure ~ 20-250 ke V photons incident from the field of view(FOV) defined by collimators, and Cs I(Na) is used as the active shielding detector to Na I(Tl) by pulse shape discrimination. Additionally, Cs I(Na) is used as an omnidirectional γ-ray monitor. The HE collimators have a diverse FOV,i.e. 1.1°×5.7°(15 units), 5.7°×5.7°(2 units), and blocked(1 unit). Therefore, the combined FOV of HE is approximately5.7°×5.7°. Each HE detector has a diameter of 190 mm resulting in a total geometrical area of approximately 5100 cm2, and the energy resolution is ~15% at 60 ke V. For each recorded X-ray event by HE, the timing accuracy is less than 10 μs and the deadtime is less than 10 μs. HE is used for observing spectra and temporal variability of X-ray sources in the 20-250 ke V band either by pointing observations for known sources or scanning observations to unveil new sources. Additionally, HE is used for monitoring the γ-ray burst in 0.2-3 Me V band. This paper not only presents the design and performance of HE instruments but also reports results of the on-ground calibration experiments. | CongZhan Liu YiFei Zhang XuFang Li XueFeng Lu Zhi Chang ZhengWei Li AiMei Zhang YongJie Jin HuiMing Yu Zhao Zhang MinXue Fu YiBao Chen JianFeng Ji YuPeng Xu JingKang Deng RenCheng Shang GuoQing Liu FangJun Lu ShuangNan Zhang YongWei Dong TiPei Li Mei Wu YanGuo Li HuanYu Wang BoBing Wu YongJie Zhang Zhi Zhang ShaoLin Xiong Yuan Liu Shu Zhang HongWei Liu YiJung Yang Fan Zhang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 9 |

| 4 | Tetrahydroisoquinolines as novel histone deacetylase inhibitors for treatment of cancer显示文摘Histone acetylation is a critical process in the regulation of chromatin structure and gene expression.Histone deacetylases(HDACs)remove the acetyl group,leading to chromatin condensation and transcriptional repression.HDAC inhibitors are considered a new class of anticancer agents and have been shown to alter gene transcription and exert antitumor effects.This paper describes our work on the structural determination and structure-activity relationship(SAR)optimization of tetrahydroisoquinoline compounds as HDAC inhibitors.These compounds were tested for their ability to inhibit HDAC 1,3,6 and for their ability to inhibit the proliferation of a panel of cancer cell lines.Among these,compound 82 showed the greatest inhibitory activity toward HDAC 1,3,6 and strongly inhibited growth of the cancer cell lines,with results clearly superior to those of the reference compound,vorinostat(SAHA).Compound 82 increased the acetylation of histones H3,H4 and tubulin in a concentration-dependent manner,suggesting that it is a broad inhibitor of HDACs. | Danqi Chen Aijun Shen Guanghua Fang Hongchun Liu Minmin Zhang Shuai Tang Bing Xiong Lanping Ma Meiyu Geng Jingkang Shen | 2016 | Acta Pharmaceutica Sinica B2016，6，1： | 4 |

| 11 | Facing challenges with hope:universal immune cells for hematologic malignancies显示文摘Many patients have achieved a favorable overall survival rate since allogenic hematopoietic stem cell transplantation(allo-HSCT)has been widely implemented to treat hematologic malignancies.However,graft-versus-host disease(GVHD)and complications of immunosuppressive drugs after allo-HSCT are the main causes of non-relapse mortality and a poor quality of life.In addition,GVHD and infusion-induced toxicity still occur with donor lymphocyte infusions(DLIs)and chimeric antigen receptor(CAR)T-cell therapy.Because of the special immune tolerance characteristics and anti-tumor ability of universal immune cells,universal immune cell therapy may strongly reduce GVHD,while simultaneously reducing tumor burden.Nevertheless,widespread application of universal immune cell therapy is mainly restricted by poor expansion and persistence efficacy.Many strategies have been applied to improve universal immune cell proliferation and persistence efficacy,including the use of universal cell lines,signaling regulation and CAR technology.In this review we have summarized current advances in universal immune cell therapy for hematologic malignancies with a discussion of future perspectives. | Yuqing Wang Ruihao Huang Zheng Wang Jingkang Xiong Xiaoqi Wang Xi Zhang | 2023 | Cancer Biology & Medicine2023，20，4： | 1 |
| 12 | Effect of heat-treatment on the surface properties of gallium phosphide nanosolids by Raman spectroscopy显示文摘Raman spectra of gallium phosphide (GaP) nanosolids (unheated and heat-treated at 598 and 723 K, respectively) were investigated. It was observed that both the longitudinal optical mode (LO) and the transverse optical mode (TO) dis-played an asymmetry on the low-wavenumber side. The scattering bands were fitted to a sum of four Lorentzians which were assigned to the LO mode, surface phonon mode, TO mode, and a combination of Ga?O?P symmetric bending and sum band formed from the X-point TA + LA phonons, respectively. Analysis of the characteristic of surface phonon mode revealed that the surface phonon peak of the GaP nanosolids could be confirmed. In the infrared spectrum of the GaP nanoparticles, we observed the bands on account of symmetric stretching and bending of PO2, as well as stretching of Ga?O. The Raman scattering intensity arising from the Ga?O?P linkages increased as increasing the heat-treatment temperature. | ZHANG Zhaochun YUE Longyi GUO Jingkang | 2006 | Rare Metals2006，25，3： | 1 |

| 14 | Positive Effects of Biochar on the Degraded Forest Soil and Tree Growth in China:A Systematic Review显示文摘Soil degradation threatens the forest sustainable productivity,particularly in afforestation system.Biochar derived from agroforestry waste or biomass can potentially improve the degraded forest soil and promote the tree growth.To expand the application of biochar for forestry productivity improvement,we here reviewed the effects and the underlying mechanisms of biochar on the degraded forest soil and tree growth.Totally 96 studies that conducted from pot to field investigations in China were summarized.The result suggested that biochar generally exerted positive effects on restoration of degraded forest soil such as that with compaction,acidification or soil erosion,which are mainly manifested by improving soil porosity,increasing pH,enhancing erosion resistance and mitigating greenhouse gas emissions.Furthermore,biochar incorporation promoted the growth of tested trees in most cases,which effect was mainly attributing to directly supplying nutrients,improving soil physio-chemical properties,enhancing the root’s nutrient absorption capacity,and enlarging the living space.In summary,current studies demonstrate that biochar has a unique potential for improving degraded forest soils and promoting tree growth.However,investigations on the underlying mechanisms and the long-term effects should be strengthened. | Jingkang Zhang Shiyuan Zhang Changhao Niu Jiang Jiang Haijun Sun | 2022 | Phyton-International Journal of Experimental Botany2022，91，8： | 1 |

| 16 | Design spherical particles of potassium peroxymonosulfate compound salt with high stability and good powder properties via an agglomeration-dissolution mechanism显示文摘With the outbreak of COVID-19,disinfection protection has become a necessary measure to prevent infection.As a new type of disinfectant,potassium peroxymonosulfate compound salt(PMS)has the advantages of good bactericidal effect,non-toxicity,high safety and stability.However,the current PMS products with irregular particle shapes lead to poor flowability,high hygroscopicity,poor stability of reactive oxygen species(ROS)and serious caking problems.In this work,an agglomeration-dissolution mechanism was designed to prepare spherical PMS particles with large size(>300μm)and high sphericity(up to 90%),effectively addressing the above problems.Shaping(dissolution and abrasion)is the key to improving sphericity,which is mainly controlled by the design of the heating mode,residence time and stirring rate.Compared with the irregular PMS particles,the large spherical particles present better flowability(angle of repose decreased by 35.80%,Carr's index decreased by 64.29%,Hausner's ratio decreased by 19.14%),lower hygroscopicity(decreased by 38.0%),lower caking ratio(decreased by 84.50%),and higher stability(the monthly loss of ROS was reduced by 61.68%).The agglomeration-dissolution mechanism demonstrates the crystallization,agglomeration,dissolution and abrasion process of inorganic salt crystals,providing an opportunity to prepare high-end inorganic crystal materials with high-quality morphologies. | Shanshan Feng Changyou Yu Shilin Guo Jinbo Ouyang Fei Yin Xiaodong Zhang Yongjian Zhang Mingyang Chen Dandan Han Junbo Gong Jingkang Wang | 2023 | Particuology2023，，9： | 0 |

| 18 | Horizontal convergence reconstruction in the longitudinal direction for shield tunnels based on conditional random field显示文摘Tunnel horizontal convergence monitoring is essential to ensure the operation safety.However,only a few representative tunnel sec-tions are chosen for monitoring due to the cost limitation.It is difficult to capture the horizontal convergence of each tunnel ring with limited measurements.Confronted with this difficulty,the paper proposes a horizontal convergence reconstruction method based on the measurements of deployed sensors.The tunnel horizontal convergence along the longitudinal direction is seen as a one-dimensional sta-tionary and ergodic random field.The reconstruction problem is then transformed into the generation of conditional random fields.Monte Carlo simulation is adopted to generate possible realizations and the mean of realizations is considered as the maximum likeli-hood reconstruction.Error analysis proves the effectiveness of the proposed reconstruction method.The proposed method is proved to be applicable in reconstructing the time-variant horizontal convergence and is verified by the monitoring results of the shield tunnel of Shanghai Metro Line 2.The effect of sensor numbers is parametrically studied,and an optimal sensor placement scheme is decided.Additional sensors placed at the deformation drastically changed location can significantly improve the performance of the proposed method. | Jingkang Shi Fei Wang Hongwei Huang Dongming Zhang | 2023 | Underground Space2023，，3： | 0 |
| 19 | SCN9A Epileptic Encephalopathy Mutations Display a Gain-offunction Phenotype and Distinct Sensitivity to Oxcarbazepine显示文摘Genetic mutants of voltage-gated sodium channels(VGSCs)are considered to be responsible for the increasing number of epilepsy syndromes.Previous research has indicated that mutations of one of the VGSC genes,SCN9A(Navl.7),result in febrile seizures and Dravet syndrome in humans.Despite these recent efforts,the electrophysiological basis of SCN9A mutations remains unclear.Here,we performed a genetic screen of patients with febrile seizures and identified a novel missense mutation of SCN9A(W1150R).Electrophysiological characterization of different SCN9A mutants in HEK293T cells,the previously-reported N641Y and K655R variants,as well as the newly-found W1150R variant,revealed that the current density of the W1150R and N641Y variants was significantly larger than that of the wild-type(WT)channel.The time constants of recovery from fast inactivation of the N641Y and K655R variants were markedly lower than in the WT channel.The W1150R variant caused a negative shift of the G-V curve in the voltage dependence of steady-state activation.All mutants displayed persistent currents larger than the WT channel.In addition,we found that oxcarbazepine(OXC),one of the antiepileptic drugs targeting VGSCs,caused a significant shift to more negative potential for the activation and inactivation in WT and mutant channels.OXC-induced inhibition of currents was weaker in the W1150R variant than in the WT.Furthermore,with administering OXC the time constant of the N641Y variant was longer than those of the other two SCN9A mutants.In all,our results indicated that the point mutation W1150R resulted in a novel gain-of-function variant.These findings indicated that SCN9A mutants contribute to an increase in seizure,and show distinct sensitivity to OXC. | Shuzhang Zhang Zhiping Zhang Yuan Shen Yudan Zhu Kun Du Jingkang Guo Yonghua Ji Jie Tao | 2020 | Neuroscience Bulletin2020，36，1： | 0 |
| 20 | Wheel Profile Optimization of Speed-up Freight Train Based on Multi-population Genetic Algorithm显示文摘The geometric shape of the wheel tread is mathematically expressed,and geometric parameters affecting the shape of the wheel were extracted as design variables.The vehicle dynamics simulation model was established based on the vehicle suspension parameters and track conditions of the actual operation,and the comprehensive dynamic parameters of the vehicle were taken as the design objectives.The matching performance of the wheel equivalent conicity with the vehicle and track parameters was discussed,and the best equivalent conicity was determined as the constraint condition of the optimization problem;a numerical calculation program is written to solve the optimization model based on a multi-population genetic algorithm.The results show that the algorithm has a fast calculation speed and good convergence.Compared with the LM profile,the two optimized profiles effectively reduce the wheelset acceleration and improve the lateral stability of the bogie and vehicle stability during straight running.Due to the optimized profile increases the equivalent conicity under larger lateral displacement of the wheelset,the lateral wheel-rail force,derailment coefficient,wheel load reduction rate,and wear index are reduced when the train passes through the curve line.This paper provides a feasible way to ensure the speed-up operation of a freight train. | Dabin CUI Pengcheng LEI Xing ZHANG Jingkang PENG | 2021 | Mechanical Engineering Science2021，3，1： | 0 |
