| 1 | Orbit determination and time synchronization for a GEO/IGSO satellite navigation constellation with regional tracking network显示文摘Aiming at regional services,the space segment of COMPASS (Phase I) satellite navigation system is a constellation of Geostationary Earth Orbit (GEO),Inclined Geostationary Earth Orbit (IGSO) and Medium Earth Orbit (MEO) satellites.Precise orbit determination (POD) for the satellites is limited by the geographic distribution of regional tracking stations.Independent time synchronization (TS) system is developed to supplement the regional tracking network,and satellite clock errors and orbit data may be obtained by simultaneously processing both tracking data and TS data.Consequently,inconsistency between tracking system and TS system caused by remaining instrumental errors not calibrated may decrease navigation accuracy.On the other hand,POD for the mixed constellation of GEO/IGSO/MEO with the regional tracking network leads to parameter estimations that are highly correlated.Notorious example of correlation is found between GEO's orbital elements and its clock errors.We estimate orbital elements and clock errors for a 3GEO+2IGSO constellation in this study using a multi-satellite precise orbit determination (MPOD) strategy,with which clock error elimination algorithm is applied to separate orbital and clock estimates to improve numerical efficiency.Satellite Laser Ranging (SLR) data are used to evaluate User Ranging Error (URE),which is the orbital error projected on a receiver's line-of-sight direction.Two-way radio-wave time transfer measurements are used to evaluate clock errors.Experimenting with data from the regional tracking network,we conclude that the fitting of code data is better than 1 m in terms of Root-Mean-Square (RMS),and fitting of carrier phase is better than 1 cm.For orbital evaluation,difference between computed receiver-satellite ranging based on estimated orbits and SLR measurements is better than 1 m (RMS).For clock estimates evaluation,2-hour linear-fitting shows that the satellite clock rates are about 1.E-10 s/s,while receiver clock rates are about 1×10 13-1×10 12 s/s.For the 72-hour POD experiment,the average differences between POD satellite clock rates estimates and clock measurements based on TS system are about 1×10 13 s/s,and for receiver clock rates,the differences are about 1×10 15 s/s. | ZHOU ShanShi HU XiaoGong WU Bin LIU Li QU WeiJing GUO Rui HE Feng CAO YueLing Wu XiaoLi ZHU LingFeng SHI Xin TAN HongLi | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,6: | 44 |

| 4 | Characterization of Arabidopsis MYB transcription factor gene AtMYB17 and its possible regulation by LEAFY and AGL15显示文摘MYB transcription factors compose one of the largest transcription factor families in Arabidopsis, which play important roles in various developmental processes as well as defense responses against environmental stresses.In this study, we report the characterization of AtMYB17 gene, a putative R2R3 type MYB gene family member in Arabidopsis.AtMYB17 was found exclusively localized in nuclear, with an activation domain at its C-terminus.AtMYB17 was highly expressed in inflorescences and siliques, especially at early flower developmental stages.The level of AtMYB17 transcripts was also found to increase after imbibition during seed germination and gradually concentrate to the shoot apex.Bioinformatics analysis identified several binding sites of LEAFY(LFY) and AGL15 in the promoter re-gion of AtMYB17.Promoter-GUS fusion analysis showed that the LFY binding sites were important in fine-tuning regulation of the spatio-temporal expression of AtMYB17 in transgenic plants.Moreover, AtMYB17 was up-regulated in 35S::AGL15 plants.Taken together, our data suggest that LFY may be involved in the regulation of AtMYB17, possibly together with AGL15, and thereafter in early inflorescence development and seed germination. | Yunfei Zhang Guangyu Cao Li-Jia Qu Hongya Gu | 2009 | Journal of Genetics and Genomics2009,36,2: | 24 |
| 5 | A novel method for purification of recombinant adeno-associated virus vectors on a large scale显示文摘A novel method for recombinant adeno-associ-ated virus (rAAV) purification on large scale is described. The method involves three steps, including chloroform treatment, PEG/NaCl precipitation and chloroform extraction. The whole procedure can be performed in four hours. Using this purification method, we can reproducibly obtain, from 4 × 109 of proviral cells cultured in roller bottles, purified rAAV-GFP stocks with titers of around 5×1013 particles/mL and purity greater than 95%. The infectious titers of the vector stocks were up to 2×1012 TU/mL, thus particle-to-infectivity rate was about 25. Under an electronic microscope, most rAAV particles appeared full and a few were in intermediate form. Empty particles were rarely seen. The purified rAAV-GFP stocks have been successfully used in in vitro and in vivo transfection experiments. Therefore, this new method offers a simple, rapid and cost-effective way for large-scale rAAV purification. | WU Xiaobing DONG Xiaoyan WU Zhijian CAO Hui NIU Dongbin QU Jianguo WANG Hong HOU Yunde | 2001 | Chinese Science Bulletin2001,46,6: | 21 |

| 10 | Heuristic Solutions of Virtual Network Embedding: A Survey显示文摘Network virtualization(NV) is considered as an enabling tool to remove the gradual ossification of current Internet. In the network virtualization environment, a set of heterogeneous virtual networks(VNs), isolated from each other, share the underlying resources of one or multiple substrate networks(SNs) according to the resource allocation strategy. This kind of resource allocation strategy is commonly known as so called Virtual Network Embedding(VNE) algorithm in network virtualization. Owing to the common sense that VNE problem is NP-hard in nature, most of VNE algorithms proposed in the literature are heuristic. This paper surveys and analyzes a number of representative heuristic solutions in the literature. Apart from the analysis of representative heuristic solutions, a taxonomy of the heuristic solutions is also presented in the form of table. Future research directions of VNE, especially for the heuristics, are emphasized and highlighted at the end of this survey. | Haotong Cao Han Hu Zhicheng Qu Longxiang Yang | 2018 | China Communications2018,15,3: | 13 |
| 11 | 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 |

| 13 | Densification Mechanism of Warm Compaction and Powder Mixture Designing Rules显示文摘By phenomenological analysis of warm compaction, it is found that, compared with the contribution of particle plastical deformation to densification of powder compact,the particle rearrangement is a dominant densification mechanism for powder warm compaction, and the plastical deformation of particles plays an important role in offering accommodating deformation for particle rearrangement and densifying powder compact at the final stage of pressing.In order to attain density gain as high as possible during warm compaction, six rules for designing warm compacting powder mixtures were proposed in detail. | CAO Shun hua,HUANG Bai yun,QU Xuan hui,YI Jian hong(State Key Laboratory for Powder Metallurgy, Central South University of Technology, Changsha 410083, China) | 2000 | Journal of Central South University2000,12,1: | 10 |
| 14 | Comprehensive Management of Daily Living Activities,behavioral and Psychological Symptoms,and Cognitive Function in Patients with Alzheimer's Disease:A Chinese Consensus on Alzheimer's Disease显示文摘Alzheimer's disease(AD)is the most common cognitive disorder in the elderly.Its main clinical manifestations are cognitive decline(C),behavioral and psychological symptoms(B),and a decline in the activities of daily living(A),also known as ABC symptoms.Early identification and evaluation of ABC symptoms are helpful for establishing the accurate diagnosis,comprehensive treatment,and prognosis of AD.To guide Chinese clinical practice for optimization of the comprehensive management of AD,in 2018,The Academy of Cognitive Disorder of China gathered 22 neurologists and gerontologists in China to build a consensus on the comprehensive management of AD.Based on a review of the evidence,the consensus summarizes the pathogenesis,pathological changes,clinical manifestations,evaluation,diagnosis,drug and non-drug treatment,and patient care for AD.Focus group discussion was used to establish a flowchart of comprehensive ABC management for AD patients.The new consensus provides a feasible AD management process for clinicians. | Jianjun Jia Jun Xu Jun Liu Yongjun Wang Yanjiang Wang Yunpeng Cao Qihao Guo Qiuming Qu Cuibai Wei Wenshi Wei Junjian Zhang Enyan Yu | 2021 | Neuroscience Bulletin2021,37,7: | 10 |
| 15 | Identifying the limiting factors driving the winter wheat yield gap on smallholder farms by agronomic diagnosis in North China Plain显示文摘North China Plain(NCP) is the primary winter wheat production region in China, characterized by smallholder farming systems. Whereas the winter wheat average yield of smallholder farmers is currently low, the yield potential and limiting factors driving the current yield gap remain unclear. Therefore, increasing the wheat yield in NCP is essential for the national food security. This study monitored wheat yield, management practices and soil nutrient data in 132 farmers’ fields of Xushui County, Baoding City, Hebei Province during 2014–2016. These data were analyzed using variance and path analysis to determine the yield gap and the contribution of yield components(i.e., spikes per hectare, grain number per spike and 1 000-grain weight) to wheat yield. Then, the limiting factors of yield components and the optimizing strategies were identified by a boundary line approach. The results showed that the attainable potential yield for winter wheat was 10 514 kg ha^–1. The yield gaps varied strongly between three yield groups(i.e., high, middle and low), which were divided by yield level and contained 44 farmers in each group, and amounted to 2 493, 1 636 and 814 kg ha^–1, respectively. For the three yield components, only spikes per hectare was significantly different(P<0.01) among the three yield groups. For all 132 farmers’ fields, correlation between yield and spikes per hectare(r=0.51, P<0.01), was significantly positive, while correlations with grain number per spike(r=–0.16) and 1 000-grain weight(r=–0.10) were not significant. The path analysis also showed that the spikes per hectare of winter wheat were the most important component to the wheat yield. Boundary line analysis showed that seeding date was the most limiting factor of spikes per hectare with the highest contribution rate(26.7%), followed by basal N input(22.1%) and seeding rate(14.5%), which indicated that management factors in the seeding step were the most important for affecting spikes per hectare. For desired spikes per hectare(>6.598×10^6 ha^–1),the seeding rate should range from 210–300 kg ha^–1, seeding date should range from 3th to 8th October, and basal N input should range from 90–180 kg ha^–1. Compared to these reasonable ranges of management measures, most of the farmers’ practices were not suitable, and both lower and higher levels of management existed. It is concluded that the strategies for optimizing yield components could be achieved by improving wheat seeding quality and optimizing farmers’ nutrient management practices in the NCP. | CAO Hong-zhu LI Ya-nan CHEN Guang-feng CHEN Dong-dong QU Hong-rui MA Wen-qi | 2019 | Journal of Integrative Agriculture2019,18,8: | 9 |
| 16 | Surges of hospital-based rhinovirus infection during the 2020 coronavirus disease-19(COVID-19)pandemic in Beijing,China显示文摘Background A series of public health preventive measures has been widely implemented in Beijing to control the corona-virus disease-19(COVID-19)pandemic since January 2020.An evaluation of the effects of these preventive measures on the spread of other respiratory viruses is necessary.Methods Respiratory specimens collected from children with acute respiratory infections were tested by NxTAGTN,respiratory pathogen panel assays during January 2017 and December 2020.Specimens characterized as rhinoviruses(RVs)were sequenced to identify the RV species and types.Then,the epidemiology results of respiratory pathogens in 2020 were compared with those from 2017 to 2019 using SPSS statistics 22.0.Results The positive rates of adenovirus(ADV),influenza virus(flu),RVs,and respiratory syncytial virus(RSV)dropped abruptly by 86.31%,94.679c,94.59%,and 92.17%,respectively,from February to May 2020,compared with the average level in the same period during 2017-2019.Positive rates of RVs then steeply increased from June 2020(13.77%),to an apex(37.25%)in August 2020,significantly higher than the average rates(22.51%)in August 2017-2019(7^=0.005).The increase,especially in group>3 years,was accompanied by the reopening of schools and kindergartens after the 23rd and 24th week of 2020 in Beijing.Conclusions Whereas the abrupt drop in viral pathogen positive rates from February to May 2020 revealed the remarkable effects of the COVID-19 preventive measures,the sharp increase in positive rates of RVs from the 23rd week of 2020 might be explained by the reopening of schools and kindergartens in Beijing. | Ruo-Xi Zhang Dong-Mei Chen Yuan Qian Yu Sun Ru-Nan Zhu Fang Wang Ya-Xin Ding Qi Guo Yu-Tong Zhou Dong Qu Ling Cao Chun-Mei Zhu Lin-Qing Zhao | 2021 | World Journal of Pediatrics2021,17,6: | 9 |

| 18 | Receptome profiling identifies KREMEN1 and ASGR1 as alternative functional receptors of SARS-CoV-2显示文摘Host cellular receptors play key roles in the determination of virus tropism and pathogenesis.However,little is known about SARS-CoV-2 host receptors with the exception of ACE2.Furthermore,ACE2 alone cannot explain the multi-organ tropism of SARS-CoV-2 nor the clinical differences between SARS-CoV-2 and SARS-CoV,suggesting the involvement of other receptor(s).Here,we performed genomic receptor profiling to screen 5054 human membrane proteins individually for interaction with the SARS-CoV-2 capsid spike(S)protein.Twelve proteins,including ACE2,ASGR1,and KREMEN1,were identified with diverse S-binding affinities and patterns.ASGR1 or KREMEN1 is sufficient for the entry of SARS-CoV-2 but not SARS-CoV in vitro and in vivo.SARS-CoV-2 utilizes distinct ACE2/ASGR1/KREMEN1(ASK)receptor combinations to enter different cell types,and the expression of ASK together displays a markedly stronger correlation with virus susceptibility than that of any individual receptor at both the cell and tissue levels.The cocktail of ASK-related neutralizing antibodies provides the most substantial blockage of SARS-CoV-2 infection in human lung organoids when compared to individual antibodies.Our study revealed an interacting host receptome of SARS-CoV-2,and identified ASGR1 and KREMEN1 as alternative functional receptors that play essential roles in ACE2-independent virus entry,providing insight into SARS-CoV-2 tropism and pathogenesis,as well as a community resource and potential therapeutic strategies for further COVID-19 investigations. | Yunqing Gu Jun Cao Xinyu Zhang Hai Gao Yuyan Wang Jia Wang Juan He Xiaoyi Jiang Jinlan Zhang Guanghui Shen Jie Yang Xichen Zheng Gaowei Hu Yuanfei Zhu Shujuan Du Yunkai Zhu Rong Zhang Jianqing Xu Fei Lan Di Qu Guoliang Xu Yun Zhao Dong Gao Youhua Xie Min Luo Zhigang Lu | 2022 | Cell Research2022,32,1: | 8 |
| 19 | Development of mouse preimplantation embryos in space显示文摘The development o f life beyond planet Earth is a long-standing quest of the human race,but whether normal mammalian embryonic development can occur in space is still unclear.Here,we show unequivocally that preimplantation mouse embryos can develop in space;but the rate of blastocyst formation and blastocyst quality are compromised.Additionally,the cells in the embryo contain severe DNA damage,while the genome of the blastocysts developed in space is globally hypomethylated with a unique set of differentially methylated regions.The developmental defects,DNA damage and epigenetic abnormalities can be largely mimicked by the treatment with ground-based low-dose radiation.However,the exposure to simulated microgravity alone does not cause major disruptions of embryonic development,indicating that radiation is the main cause for the developmental defects.This work advances the understanding of embryonic development in space and reveals long-term extreme low-dose radiation as a hazardous factor for mammalian reproduction. | Xiaohua Lei Yujing Cao Baohua Ma Yunfang Zhang Lina Ning Jingjing Qian Liwen Zhang Yongcun Qu Tao Zhang Dehong Li Qi Chen Junchao Shi Xudong Zhang Chiyuan Ma Ying Zhang Enkui Duan | 2020 | National Science Review2020,7,9: | 8 |
