| 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 |

| 3 | Postmarketing safety evaluation: depside salt injection made from Danshen(Radix Salviae Miltiorrhizae)显示文摘OBJECTIVE: To systematically examine the postmarketing safety of depside salt injection made from Danshen(Radix Salviae Miltiorrhizae),identifythe potential risk factors, and ensure its clinical safety.METHODS: We examined a comprehensive series of studies on the production process, quality standards, pharmacology, population pharmacokinetics, and safety evaluation of depside salt injection made from Danshen(Radix Salviae Miltiorrhizae). Data from Ⅰ-Ⅳ clinical drug trials, hospital information systems(HIS), and spontaneous reporting systems(SRS) were also analyzed.RESULTS: The effective components of salvianolic acid salt content reached almost 100%, and the magnesium lithospermate B content reached morethan 80%. The median lethal dose(LD50) calculated by the Bliss method was 1.49 g/kg, with 95%confidence intervals of 1.29-1.72 g/kg. Long-term tests on Beagle dogs indicated that doses of less than 80 mg/kg were safe and doses of 320 mg/kg were toxic. Adverse drug reactions(ADRs) included digestive disorders; drug-induced erythrocyte deformation in lung, liver, spleen, kidney, bone marrow, intestinal mucosa, lymph nodes, and other tissues; megakaryocytes in lung, liver, and spleen resulting from mild hemolysis; and mild hyperplasia in bone marrow hematopoietic tissue. Other studies indicated no irritative effect of the injection on local tissues and blood vessels, and no allergic reactions, erythrocyte coagulation, or hemolysis. SRS data showed that the most common ADRs were headache, head distention, dizziness, facial flushing, skin itching, thrombocytopenia, and the reversibility of elevated Aspartate transaminase. HIS data indicated no damage to renal function from using depside salt injection made from Danshen(Radix Salviae Miltiorrhizae) at a dosage higher than the recommended dose.CONCLUSION: This study analyzes the clinical characteristics of ADRs from depside salt injection made from Danshen(Radix Salviae Miltiorrhizae),and discusses the factors influencing such reactions. It provides scientific reference and recommendations for clinically safe medication of the Danshen injection. | Yanpeng Chang Wen Zhang Yanming Xie Xiangyang Xu Rendi Sun Zheng Wang Ruihua Yan | 2014 | Journal of Traditional Chinese Medicine2014，34，6： | 8 |
| 4 | Biomimetic injectable hydrogel microspheres with enhanced lubrication and controllable drug release for the treatment of osteoarthritis显示文摘The occurrence of osteoarthritis(OA)is highly associated with the reduced lubrication property of the joint,where a progressive and irreversible damage of the articular cartilage and consecutive inflammatory response dominate the mechanism.In this study,bioinspired by the super-lubrication property of cartilage and catecholamine chemistry of mussel,we successfully developed injectable hydrogel microspheres with enhanced lubrication and controllable drug release for OA treatment.Particularly,the lubricating microspheres(GelMA@DMA-MPC)were fabricated by dip coating a self-adhesive polymer(DMA-MPC,synthesized by free radical copolymerization)on superficial surface of photo-crosslinked methacrylate gelatin hydrogel microspheres(GelMA,prepared via microfluidic technology),and encapsulated with an anti-inflammatory drug of diclofenac sodium(DS)to achieve the dual-functional performance.The tribological test and drug release test showed the enhanced lubrication and sustained drug release of the GelMA@DMA-MPC microspheres.In addition,the functionalized microspheres were intra-articularly injected into the rat knee joint with an OA model,and the biological tests including qRT-PCR,immunofluorescence staining assay,X-ray radiography and histological staining assay all revealed that the biocompatible microspheres provided significant therapeutic effect against the development of OA.In summary,the injectable hydrogel microspheres developed herein greatly improved lubrication and achieved sustained local drug release,therefore representing a facile and promising technique for the treatment of OA. | Ying Han Jielai Yang Weiwei Zhao Haimang Wang Yulong Sun Yuji Chen Jing Luo Lianfu Deng Xiangyang Xu Wenguo Cui Hongyu Zhang | 2021 | Bioactive Materials2021，6，10： | 8 |

| 7 | Versatile Piriformospora indica and Its Potential Applications in Horticultural Crops显示文摘Modern horticultural crop production systems target the exploitation of sustainable techniques for crop improvement while maintaining balance with the environment. Several beneficial microbes have been investigated and have yielded remarkable results. The endophytic fungus, Piriformospora indica, is one microbe group with the potential to offer numerous benefits and opportunities in modern horticultural crop production. This plant growth-promoting mycorrhizal fungus is of particular interest due to its beneficial implications in plant growth and development. The fungus has been experimentally proven to significantly improve water and nutrient/mineral absorption, early flowering, seed production/germination and plant photosynthetic capability, growth rates;especially in nutrient-deprived soils, alter the production of secondary metabolites, and promote adaptation, tolerance and/or resistance to biotic and abiotic stressors. Its unique capability to be axenically cultured makes it feasible for research and application. These attributes in combinations with its broad host range, offer immense potential for this fungus for research in horticultural plant improvement. Thus, this review highlights the potential applications of P. indica in horticultural crops research and production. | Raphael Anue Mensah Dan Li Fan Liu Na Tian Xueli Sun Xiangyang Hao Zhongxiong Lai Chunzhen Cheng | 2020 | Horticultural Plant Journal2020，6，2： | 6 |
| 8 | The 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 | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 5 |
| 9 | NEXT:a neural network framework for next POI recommendation显示文摘The task of next POI recommendations has been studied extensively in recent years.However,developing a unified recommendation framework to incorporate multiple factors associated with both POIs and users remains challenging,because of the heterogeneity nature of these information.Further,effective mechanisms to smoothly handle cold-start cases are also a difficult topic.Inspired by the recent success of neural networks in many areas,in this paper,we propose a simple yet effective neural network framework,named NEXT,for next POI recommendations.NEXT is a unified framework to learn the hidden intent regarding user's next move,by incorporating different factors in a unified manner.Specifically,in NEXT,we incorporate meta-data information,e.g.,user friendship and textual descriptions of POIs,and two kinds of temporal contexts(i.e.,time interval and visit time).To leverage sequential relations and geographical influence,we propose to adopt DeepWalk,a network representation learning technique,to encode such knowledge.We evaluate the effectiveness of NEXT against other state-of-the-art alternatives and neural networks based solutions.Experimental results on three publicly available datasets demonstrate that NEXT significantly outperforms baselines in real-time next POI recommendations.Further experiments show inherent ability of NEXT in handling cold-start. | Zhiqian ZHANG Chenliang LI Zhiyong WU Aixin SUN Dengpan YE Xiangyang LUO | 2020 | Frontiers of Computer Science2020，14，2： | 5 |

| 12 | Sustainable management of Chinese grasslands—issues and knowledge显示文摘China has almost 400 Mhm^2 of grasslands,90% of which is considered degraded to varying degrees,on which 16 million herders depend for their livelihoods and many more indirectly, along the value-adding chain.Since 1950, average stocking rates across China have increased 4-fold. National policies have focused over recent decades on finding ways to rehabilitate the degraded grasslands, to sustain livestock production from them, and to improve the livelihoods of herder households, who are among the poorest people in China. A large collaborative program commenced in the early 2000 s to help find solutions to the sustainable management of grasslands.This paper summarizes key findings of many research projects, identifies where knowledge is weak and argues that the successful rehabilitation of grasslands will also require policies that provide incentives and support for herders as they move from a focus on survival to a focus on production of higher quality products, for which consumers are increasingly willing to pay. A key focus is to emphasize the improvement of animal production per head. When this is done, it naturally leads to lower stocking rates, which in turn provides the opportunities for grasslands to recover. Across a range of experiments, farm demonstrations and analyses using models, in Inner Mongolia and Gansu, a consistent result has been that a 50% reduction in stocking rates, improves net household income and starts the process of grassland rehabilitation.Rather than focusing on stocking rates, better management of grasslands could be achieved by maintaining the grasslands above critical values for herbage mass, values that help optimize botanical composition, reduce soil erosion, optimize animal growth rates and aid ecosystem functions. Managing to critical values for herbage mass is likely to be more effective than efforts to calculate sustainable stocking rates. An early summer rest is valuable for aiding grassland rehabilitation and summer productivity, but a total grazing ban(typically for 5 years)may not achieve its aims as evidence shows it may take 10–15 years to achieve a better grassland state. Lessdesirable plant species often increase in degraded grasslands that are rested and grazing can help manage those species. Surveys of herders indicate they have very mixed views on the benefits of total grazing bans that are unlikely to rehabilitate grasslands to an ideal botanical composition.The current objective is to work with grasslands that herders now have and optimize the existing composition.Grazing grasslands in winter results primarily in weight loss by animals and there is now evidence of how winter grazing reduces grassland growth in the next summer. It is better to keep animals in well-built sheds and feed them better, improved feeding through the cold months is required. In addition to the application of results from national programs designed to improve grasslands, it will be important to train herders as they move from survival to production, to foster the development of better markets for their livestock products, to devise better financial support for herder businesses and to revise land tenure arrangements so that herders can expand the area of land they graze on better terms than apply at present. | David KEMP Guodong HAN Fujiang HOU Xiangyang HOU Zhiguo LI Yi SUN Zhongwu WANG Jianping WU Xiaoqing ZHANG Yingjun ZHANG Xuyin GONG | 2018 | Frontiers of Agricultural Science and Engineering2018，5，1： | 3 |
| 13 | Overview 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.

| 15 | A quasi-3D Fano resonance cavity on optical fiber end-facet for high signal-to-noise ratio dip-and-read surface plasmon sensing显示文摘Surface plasmon devices mounted at the end-facets of optical fibers are appealing candidates for rapid and point-of-care sensing applications,by offering a special dip-and-read operation mode.At present,these devices’noise-equivalent limits-of-detection lag far behind the free-space counterparts,leaving them incapable of most biosensing applications.Here we report a quasi-3D Fano resonance cavity and its fabrication method to fundamentally improve the quality factor and coupling efficiency for fiber-coupled surface plasmon resonance.In this device,the Fano resonance combines the high coupling efficiency of a Fabry-Pérot etalon and the high quality factor resonance of a plasmonic crystal cavity.The quasi-3D device was fabricated on a planar substrate and transferred to a single-mode fiber end-facet,which requires a low-adhesion yet surface-plasmon-tunneling interface between the device and the planar substrate.Such an interface was realized with a nanocap-slit unit structure,of which the plasmonic crystal was consisted.A noise-equivalent limit of detection of~10-7 RIU was experimentally obtained,allowing bovine serum albumin physical adsorption to be distinguished at ng mL-1 level concentrations.Therefore,breaking through the long-standing signal-to-noise ratio bottleneck,this work makes fiber end-facet surface plasmon devices into one of high sensitivity label-free sensing technologies.At the same time,it provides an enabling top-down fabrication technology for making 3D plasmonic structures on fiber end-facets at the nanometer scale. | Xiaqing Sun Zeyu Lei Hao Zhong Chenjia He Sihang Liu Qingfeng Meng Qingwei Liu Shengfu Chen Xiangyang Kong Tian Yang | 2022 | Light(Advanced Manufacturing)2022，3，4： | 2 |

| 18 | Effects of organic mulching on soil aggregate stability and aggregate binding agents in an urban forest in Beijing, China显示文摘Urban forest soil is often disturbed by rapid urbanization. Organic mulching is effective for improving soil quality and aggregate stability. This study evaluated how soil binding agents changed aggregate stability through organic mulching in urban forest soils. Three treatments were applied in Jiufeng National Forest Park, Beijing: (1) no organic mulch (control);(2) wood chips alone (5 cm thickness);and, (3) wood chips + wood compost (This mulch was divided into two layers, the upper layer of wood chips (2.5 cm), the lower layer wood compost (2.5 cm)). Soil samples were collected from the surface 10- cm soil layer and fraction into four aggregates. Glomalin-related soil protein and soil organic carbon were measured in bulk soil and the four aggregates. The results show that wood chips + wood compost increased the proportion of large and small macroaggregates, mean weight diameter and geometric mean diameter. The total and easily extractable glomalin-related soil protein were higher in the wood chips + wood compost. However, soil organic carbon was lower in the wood chips alone application compared to the controls and wood chips + wood compost. Easily extractable / total glomalin-related soil protein and glomalin-related soil protein / soil organic carbon ratios of wood chips alone and wood chips + wood compost had increased trend compared to the controls but did not reach significant levels (p > 0.05). Mean weight diameter and geometric mean diameter correlated positively with total and easily extractable glomalin-related soil protein but were not positively correlated with soil organic carbon, the ratios of easily extractable and total glomalin-related soil protein, and the ratios of glomalin-related soil protein and soil organic carbon. Redundancy analysis revealed that total glomalin-related soil protein was the most important driver for soil aggregate stability, especially the total glomalin-related soil protein of small macroaggregates. The results suggest that wood chips + wood compost enhanced soil aggregate stability through the increase of glomalin-related soil protein. Wood chips alone cannot enhance soil aggregate stability in urban forests in the short term. | Wei Zhou Xiangyang Sun Suyan Li Tiantian Du Yi Zheng Zhihui Fan | 2022 | Journal of Forestry Research2022，33，3： | 2 |
