| 1 | Field experiment on a robust hierarchical metropolitan quantum cryptography network显示文摘A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and the corresponding application software shows a big step toward the practical user-oriented network with a high security level. | XU FangXing CHEN Wei WANG Shuang YIN ZhenQiang ZHANG Yang LIU Yun ZHOU Zheng ZHAO YiBo LI HongWei LIU Dong HAN ZhengFu GUO GuangCan | 2009 | Chinese Science Bulletin2009，54，17： | 40 |
| 2 | The Chromosome-Level Genome Sequence of the Autotetraploid Alfalfa and Resequencing of Core Germplasms Provide Genomic Resources for Alfalfa Research显示文摘Alfalfa(Medicago sativa)is one of the most important forage crops in the world;however,its molecular genetics and breeding research are hindered due to the lack of a high-quality reference genome.Here,we report a de novo assembled 816-Mb high-quality,chromosome-level haploid genome sequence for‘Zhongmu No.1’alfalfa,a heterozygous autotetraploid.The contig N50 is 3.92 Mb,and 49165 genes are annotated in the genome.The alfalfa genome is estimated to have diverged from M.truncatula approximately 8 million years ago.Genomic population analysis of 162 alfalfa accessions revealed high genetic diversity,weak population structure,and extensive gene flow from wild to cultivated alfalfa.Genome-wide association studies identified many candidate genes associated with important agronomic traits.Furthermore,we showed that MsFTa2,a Flowering Locus T homolog,whose expression is upregulated in salt-resistant germplasms,may be associated with fall dormancy and salt resistance.Taken together,these genomic resources will facilitate alfalfa genetic research and agronomic improvement. | Chen Shen Huilong Du Zhuo Chen Hongwei Lu Fugui Zhu Hong Chen Xiangzhao Meng Qianwen Liu Peng Liu Lihua Zheng Xiuxiu Li Jiangli Dong Chengzhi Liang Tao Wang | 2020 | Molecular Plant2020，13，9： | 21 |

| 4 | Burden of colorectal cancer in China, 1990-2017: Findings from the Global Burden of Disease Study 2017显示文摘Objective: Our goal is to analyze the trend of colorectal cancer(CRC) regarding the death, incidence and prevalence rates over time, and to provide epidemiological knowledge basis for health policy revision by comparing data about fatal outcomes of CRC in 2017 to those data in 1990, which was extracted from the Global Burden of Disease(GBD).Methods: The time trend and changes of CRC burden from 1990 to 2017 were measured by using the methods and results from the Institute for Health Metrics and Evaluation(IHME) GBD 2017, based on the rates of death,incidence and prevalence.Results: The death rate of CRC is 13.24/100,000, accounting for 1.79% of total deaths in China in 2017. In1990, CRC ranked 21 st in all causes of death in China compared to its 11 th ranking in 2017. The death, incidence and prevalence rate of CRC were standardized by the age scale of the global population in 2010, the change of standardized death rate of CRC was not significant, from 9.33/100,000 in 1990 to 10.10/100,000 in 2017. The standardized incidence rate of CRC significantly increased from 12.18/100,000 in 1990 to 22.42/100,000 in 2017.The standardized prevalence rate of CRC significantly increased from 44.55/100,000 in 1990 to 118.40/100,000 in2017. The trend of the prevalence rate in both genders grow higher in 2017 compared to the 1990, resulting in141.6%, 209.8% and 189.0% for the studied three age groups(15-49, 50-69 and 70+ years old), respectively. The death rate increased in the age groups of 50-69 and 70+ years in both genders(8.6% and 31.0% respectively), in contrast to a decrease of death rate in the age group of 15-49 years old(-10.8%).Conclusions: China experienced a stunning increase in terms of incidence and prevalence rate of CRC from1990 to 2017. To decrease the burden of CRC, prevention and management of known risk factors should be promoted through national polices. | Jie Yin Zhigang Bai Jun Zhang Zhi Zheng Hongwei Yao Pengpeng Ye Jun Li Xin Gao Zhongtao Zhang | 2019 | Chinese Journal of Cancer Research2019，31，3： | 16 |
| 5 | The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence. | Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，8： | 14 |
| 6 | Multi-type ant system algorithm for the time dependent vehicle routing problem with time windows显示文摘The time dependent vehicle routing problem with time windows(TDVRPTW) is considered. A multi-type ant system(MTAS) algorithm hybridized with the ant colony system(ACS)and the max-min ant system(MMAS) algorithms is proposed. This combination absorbs the merits of the two algorithms in solutions construction and optimization separately. In order to improve the efficiency of the insertion procedure, a nearest neighbor selection(NNS) mechanism, an insertion local search procedure and a local optimization procedure are specified in detail. And in order to find a balance between good scouting performance and fast convergence rate, an adaptive pheromone updating strategy is proposed in the MTAS. Computational results confirm the MTAS algorithm's good performance with all these strategies on classic vehicle routing problem with time windows(VRPTW) benchmark instances and the TDVRPTW instances, and some better results especially for the number of vehicles and travel times of the best solutions are obtained in comparison with the previous research. | DENG Ye ZHU Wanhong LI Hongwei ZHENG Yonghui | 2018 | Journal of Systems Engineering and Electronics2018，29，3： | 13 |
| 7 | Target classification with low-resolution radar based on dispersion situations of eigenvalue spectra显示文摘Most low-resolution radar systems, especially ground surveillance radar systems, work at relatively low pulse repeat frequency (PRF) and with short time-on-target (TOT) (duration in scanning). Low PRF leads to Doppler ambiguity and short TOT results in low Doppler resolution, which poses a problem to target classification with low-resolution radar based on the jet engine modulation (JEM) characteristic of radar echo. From the pattern classification viewpoint, we propose a method of using dispersion situations of JEM eigenvalue spectra to categorize aeroplanes into three kinds, namely turbojet aircraft, prop aircraft and helicopter. We analyze the mathematical model of JEM echoes consisting of a series of line spectra and regard them as a sum of several series of harmonious waves. Classification features can be extracted based on the harmonious wave sum model. Some schemes for extracting features from echoes within or between pulses are proposed. Low-dimensional features are extracted to reduce computation burden. Our methods do not compensate for the fuselage echoes and are insensitive to the variation of fuselage Doppler. The feasibility of our methods is demonstrated by simulation experiment. | CHEN Feng, LIU HongWei, DU Lan & BAO Zheng National Laboratory of Radar Signal Processing, Xidian University, Xi’an 710071, China | 2010 | Science China(Information Sciences)2010，53，7： | 12 |
| 8 | Electron force-induced dislocations annihilation and regeneration of a superalloy through electrical in-situ transmission electron microscopy observations显示文摘What effect does electric current do on dislocation evolution of metals keeps being a confusing question to be answered and proved. To this end, the dislocation evolution of a superalloy with electric current was directly observed by electrical in-situ transmission electron microscopy in this work. Dislocations annihilation at first and then regeneration was found for the first time, which directly proves the existence of electron force during the electrically-assisted manufacturing. Dislocations regeneration would be driven by the electron force and the resistance softening by the local Joule heating effect. Resultantly,a base could be provided for future electrically-assisted research. | Xina Zhang Hongwei Li Mei Zhan Zebang Zheng Jia Gao Guangda Shao | 2020 | Journal of Materials Science & Technology2020，36，1： | 12 |

| 10 | 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 |

| 12 | TaSCL14,a Novel Wheat(Triticum aestivum L.)GRAS Gene,Regulates Plant Growth,Photosynthesis,Tolerance to Photooxidative Stress,and Senescence显示文摘Rates of photosynthesis,tolerance to photooxidative stress,and senescence are all important physiological factors that affect plant development and thus agricultural productivity.GRAS proteins play essential roles in plant growth and development as well as in plant responses to biotic and abiotic stresses.So far few GRAS genes in wheat(Triticum aestivum L.)have been characterized.A previous transcriptome analysis indicated that the expression of a GRAS gene(TaSCL14) was induced by high-light stress in Xiaoyan 54(XY54),a common wheat cultivar with strong tolerance to high-light stress.In this study,TaSCL14 gene was isolated from XY54 and mapped on chromosome 4A.TaSCL14 was expressed in various wheat organs,with high levels in stems and roots.Our results confirmed that TaSCL14 expression was indeed responsive to high-light stress.Barley stripe mosaic virus(BSMV)-based virus-induced gene silencing(VIGS)of TaSCL14 in wheat was performed to help characterize its potential functions.Silencing of TaSCL14 resulted in inhibited plant growth,decreased photosynthetic capacity,and reduced tolerance to photooxidative stress.In addition,silencing of TaSCL14 in wheat promoted leaf senescence induced by darkness.These results suggest that TaSCL14 may act as a multifunctional regulator involved in plant growth,photosynthesis,tolerance to photooxidative stress,and senescence. | Kunmei Chen Hongwei Li Yaofeng Chen Qi Zheng Bin Li Zhensheng Li | 2015 | Journal of Genetics and Genomics2015，42，1： | 11 |
| 13 | In vivo self-assembled small RNAs as a new generation of RNAi therapeutics显示文摘RNAi therapy has undergone two stages of development,direct injection of synthetic siRNAs and delivery with artificial vehicles or conjugated ligands;both have not solved the problem of efficient in vivo siRNA delivery.Here,we present a proof-of-principle strategy that reprogrammes host liver with genetic circuits to direct the synthesis and self-assembly of siRNAs into secretory exosomes and facilitate the in vivo delivery of siRNAs through circulating exosomes.By combination of different genetic circuit modules,in vivo assembled siRNAs are systematically distributed to multiple tissues or targeted to specific tissues(e.g.,brain),inducing potent target gene silencing in these tissues.The therapeutic value of our strategy is demonstrated by programmed silencing of critical targets associated with various diseases,including EGFR/KRAS in lung cancer,EGFR/TNC in glioblastoma and PTP1B in obesity.Overall,our strategy represents a next generation RNAi therapeutics,which makes RNAi therapy feasible. | Zheng Fu Xiang Zhang Xinyan Zhou Uzair Ur-Rehman Mengchao Yu Hongwei Liang Hongyuan Guo Xu Guo Yan Kong Yuanyuan Su Yangyang Ye Xiuting Hu Wei Cheng Jinrong Wu Yanbo Wang Yayun Gu Sheng-feng Lu Dianqing Wu Ke Zen Jing Li Chao Yan Chen-Yu Zhang Xi Chen | 2021 | Cell Research2021，31，6： | 10 |
| 14 | Molecular Cytogenetic Characterization and Stem Rust Resistance of Five Wheat-Thinopyrum ponticum Partial Amphiploids显示文摘Partial amphiploids created by crossing common wheat(Triticum aestivum L.) and Thinopyrum ponticum(Podp.) Barkworth & D.R.Dewey are important intermediates in wheat breeding because of their resistance to major wheat diseases.In this study,we examined the chromosome compositions of five Xiaoyan-series wheat-Th.ponticum partial amphiploids(Xiaoyan 68.Xiaoyan 693,Xiaoyan 784,Xiaoyan 7430,and Xiaoyan 7631) using GISH,multicolor-GISH.and multicolor-FISH.We found several chromosome changes in these lines.For example,wheat chromosomes 1B and 2B were added in Xiaoyan 68 and Xiaoyan 7430,respectively,while wheat chromosome6 B was eliminated from Xiaoyan 693 and Xiaoyan 7631.Chromosome rearrangements were also detected in these amphiploids.including an interspecific translocation involving chromosome 4D and some inlergenomic translocations,such as A-B and A-D translocations,among wheat genomes.Analysis of the Th.ponticum chromosomes in the amphiploids showed that some lines shared the same alien chromosomes.We also evaluated these partial amphiploids for resistance to nine races of stem rust,including TTKSK(commonly known as Ug99).Three lines,Xiaoyan 68,Xiaoyan 784,and Xiaoyan 7430,exhibited excellent resistance to ail nine races,and could therefore be valuable sources of stem rust resistance in wheat breeding. | Qi Zheng Zhenling Lv Zhixia Niu Bin Li Hongwei Li Steven S.Xu Fangpu Han Zhensheng Li | 2014 | Journal of Genetics and Genomics2014，41，11： | 9 |
| 15 | Radar automatic target recognition based on feature extraction for complex HRRP显示文摘Radar high-resolution range profile(HRRP) has received intensive attention from the radar automatic target recognition(RATR) community.Usually,since the initial phase of a complex HRRP is strongly sensitive to target position variation,which is referred to as the initial phase sensitivity in this paper,only the amplitude informa-tion in the complex HRRP,called the real HRRP in this paper,is used for RATR,whereas the phase information is discarded.However,the remaining phase infor-mation except for initial phases in the complex HRRP also contains valuable target discriminant information.This paper proposes a novel feature extraction method for the complex HRRP.The extracted complex feature vector,referred to as the complex feature vector with difference phases,contains the difference phase in-formation between range cells but no initial phase information in the complex HRRP.According to the scattering center model,the physical mechanism of the proposed complex feature vector is similar to that of the real HRRP,except for reserving some phase information independent of the initial phase in the complex HRRP.The recognition algorithms,frame-template establishment methods and preprocessing methods used in the real HRRP-based RATR can also be applied to the proposed complex feature vector-based RATR.Moreover,the components in the complex feature vector with difference phases approximate to follow Gaussian distribution,which make it simple to perform the statistical recognition by such complex feature vector.The recognition experiments based on measured data show that the pro-posed complex feature vector can obtain better recognition performance than the real HRRP if only the cell interval parameters are properly selected. | DU Lan LIU HongWei BAO Zheng ZHANG JunYing | 2008 | Science in China(Series F)2008，51，8： | 9 |

| 19 | Zr-MOFs loaded on polyurethane foam by polydopamine for enhanced dye adsorption显示文摘Zirconium-based metal-organic frameworks(Zr-MOFs)have attracted widespread attention due to their high specific surface area,high porosity,abundant metal active sites and excellent hydrothermal stability.However,Zr-MOFs materials are mostly powdery in nature and thus difficult to separate from aqueous media,which limits their application in wastewater treatment.In this study,PDA/Zr-MOFs/PU foam was constructed by growing Zr-MOFs nanoparticles on a dopamine-modified polyurethane foam substrate by in-situ hydrothermal synthesis as an adsorbent for removing dyes from wastewater.The results demonstrated that the polydopamine coating improves the dispersion of the Zr-MOFs nanoparticles on the substrate and enhances the interaction between the Zr-MOFs nanoparticles and the PU foam substrate.As a result,compared with Zr-MOFs/PU foam,the prepared PDA/ZrMOFs/PU foam exhibits higher adsorption capacity for crystal violet(CV)(63.38 mg/g)and rhodamine B(RB)(67.73 mg/g),with maximum adsorption efficiencies of CV and RB of 98.4%(pH=11)and 93.5%(pH=7),respectively,at a concentration of 10 mg/L.The PDA/Zr-MOFs/PU foam can simultaneously remove CV and RB from the mixed solution.Moreover,the PDA/ZrMOFs/PU foam still exhibits high stability and reusability after five cycles. | Jingjing Zhao Linqiong Xu Yaozhuo Su Hongwei Yu Hui Liu Shaoping Qian Wenge Zheng Yongqing Zhao | 2021 | Journal of Environmental Sciences2021，33，3： | 6 |
