| 1 | Distribution of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in surface water and sediments from Baiyangdian Lake in North China显示文摘Persistent organochlorine compounds,including hexachlorocyclohexanes (HCHs),dichlorodiphenyltrichloroethanes (DDTs) and polychlorinated biphenyls (PCBs) were analyzed in surface water and sediments from Baiyangdian Lake,North China.Total concentrations of HCHs,DDTs and PCBs in surface water were in the range of 3.13-10.60,4.05-20.59 and 19.46-131.62 ng/L,respectively,and total concentrations of HCHs,DDTs and PCBs in sediments were 1.75-5.70,0.91-6.48 and 5.96-29.61 ng/g dry weight,respectively.Among the groups of HCHs (sum of α-HCH,β-HCH,γ-HCH and δ-HCH) and DDTs (sum of DDT,DDD and DDE),the predominance of β-HCH,DDE and DDD in water and sediment samples was clearly observed.This observation suggested that β-HCH was resistant to biodegradation and the DDTs had been transformed to its metabolites,DDE and DDD.For PCBs,penta-,hexa-and hepta-chlorinated congeners were the most abundant compounds in the both phases.Furthermore,the partitioning of chlorinated compounds between sediment and water was investigated to understand their transport and fates in aquatic ecosystems.The results indicated that average logs of organic carbon-normalized sediment-water partition coefficients (logK'oc) for OCPs varied between 3.20 and 5.53,and for PCBs,logK'oc values ranged from 3.19 to 5.57.The observed logK'oc was lower than their equilibrium logKoc predicted from linear model,which may be attributed to the solubility enhancement effect of colloidal matter in water phase and the disequilibrium between sediment and water. | Guohua Dai Xinhui Liu Gang Liang Xu Han Liu Shi Dengmiao Cheng Wenwen Gong | 2011 | Journal of Environmental Sciences2011，23，10： | 44 |
| 2 | Approximate Maximum Likelihood Algorithm for Moving Source Localization Using TDOA and FDOA Measurements显示文摘A closed-form approximate maximum likelihood(AML) algorithm for estimating the position and velocity of a moving source is proposed by utilizing the time difference of arrival(TDOA) and frequency difference of arrival(FDOA) measurements of a signal received at a number of receivers.The maximum likelihood(ML) technique is a powerful tool to solve this problem.But a direct approach that uses the ML estimator to solve the localization problem is exhaustive search in the solution space,and it is very computationally expensive,and prohibits real-time processing.On the basis of ML function,a closed-form approximate solution to the ML equations can be obtained,which can allow real-time implementation as well as global convergence.Simulation results show that the proposed estimator achieves better performance than the two-step weighted least squares(WLS) approach,which makes it possible to attain the Cramér-Rao lower bound(CRLB) at a sufficiently high noise level before the threshold effect occurs. | YU Huagang HUANG Gaoming GAO Jun WU Xinhui | 2012 | Chinese Journal of Aeronautics2012，25，4： | 28 |

| 4 | Changes in visibility with PM_(2.5) composition and relative humidity at a background site in the Pearl River Delta region显示文摘In fall–winter, 2007–2013, visibility and light scattering coefficients(b sp) were measured along with PM_(2.5)mass concentrations and chemical compositions at a background site in the Pearl River Delta(PRD) region. The daily average visibility increased significantly(p < 0.01) at a rate of 1.1 km/year, yet its median stabilized at ~13 km. No haze days occurred when the 24-hr mean PM_(2.5)mass concentration was below 75 μg/m^3. By multiple linear regression on the chemical budget of particle scattering coefficient(b sp), we obtained site-specific mass scattering efficiency(MSE) values of 6.5 ± 0.2, 2.6 ± 0.3, 2.4 ± 0.7 and 7.3 ± 1.2 m2/g,respectively, for organic matter(OM), ammonium sulfate(AS), ammonium nitrate(AN) and sea salt(SS). The reconstructed light extinction coefficient(b ext) based on the Interagency Monitoring of Protected Visual Environments(IMPROVE) algorithm with our site-specific MSE revealed that OM, AS, AN, SS and light-absorbing carbon(LAC) on average contributed 45.9% ± 1.6%,25.6% ± 1.2%, 12.0% ± 0.7%, 11.2% ± 0.9% and 5.4% ± 0.3% to light extinction, respectively.Averaged b ext displayed a significant reduction rate of 14.1/Mm·year(p < 0.05); this rate would be 82% higher if it were not counteracted by increasing relative humidity(RH) and hygroscopic growth factor(f(RH)) at rates of 2.5% and 0.16/year-1(p < 0.01), respectively, during the fall–winter, 2007–2013. This growth of RH and f(RH) partly offsets the positive effects of lowered AS in improving visibility, and aggravated the negative effects of increasing AN to impair visibility. | Xiaoxin Fu Xinming Wang Qihou Hu Guanghui Li Xiang Ding Yanli Zhang Quanfu He Tengyu Liu Zhou Zhang Qingqing Yu Ruqing Shen Xinhui Bi | 2016 | Journal of Environmental Sciences2016，28，2： | 18 |
| 5 | Reliability Design for Impact Vibration of Hydraulic Pressure Pipeline Systems显示文摘The research of reliability design for impact vibration of hydraulic pressure pipeline systems is still in the primary stage,and the research of quantitative reliability of hydraulic components and system is still incomplete.On the condition of having obtained the numerical characteristics of basic random parameters,several techniques and methods including the probability statistical theory,hydraulic technique and stochastic perturbation method are employed to carry out the reliability design for impact vibration of the hydraulic pressure system.Considering the instantaneous pressure pulse of hydraulic impact in pipeline,the reliability analysis model of hydraulic pipeline system is established,and the reliability-based optimization design method is presented.The proposed method can reflect the inherent reliability of hydraulic pipe system exactly,and the desired result is obtained.The reliability design of hydraulic pipeline system is achieved by computer programs and the reliability design information of hydraulic pipeline system is obtained.This research proposes a reliability design method,which can solve the problem of the reliability-based optimization design for the hydraulic pressure system with impact vibration practically and effectively,and enhance the quantitative research on the reliability design of hydraulic pipeline system.The proposed method has generality for the reliability optimization design of hydraulic pipeline system. | ZHANG Tianxiao LIU Xinhui | 2013 | Chinese Journal of Mechanical Engineering2013，26，5： | 17 |
| 6 | Vision,application scenarios,and key technology trends for 6G mobile communications显示文摘With the global commercialization of the fifth-generation(5G)network,many countries,including China,USA,European countries,Japan,and Korea,have started exploring 6G mobile communication network,following the tradition of“planning the next while commercializing one generation”.Currently,studies on 6G networks are at the infancy stage.Research on the vision and requirements for 6G is still ongoing,and the industry is yet to clarify the key enabling technologies for 6G.However,6G will certainly build on the success of 5G.Therefore,developing high-quality 5G networks and seamlessly integrating 5G with verticals are the priorities before 2030,when 6G is projected to be commercialized.Also,global 5G standards will keep evolving to better support vertical applications.As a milestone,the Third-Generation Partnership Project(3GPP)published Release 16 in July 2020,which continuously enhanced the capabilities of mobile broadband service based on Release 15 and realized the support for low-delay and high-reliability applications,such as Internet of Vehicles and industrial Internet.Currently,3GPP is working on Releases 17 and 18,focusing on meeting the demands of medium-and high-data-rate machine communication with low-cost and high-precision positioning,which will be published in June 2022.Thus,6G networks will further expand the application fields and scope of the Internet of Things to accommodate those services and applications that are beyond the capabilities of 5G networks.Herein,we present our vision,application scenarios,and key technological trends for 6G networks.Furthermore,we propose several future research opportunities in 6G networks with regard to industrialization and standardization. | Zhiqin WANG Ying DU Kejun WEI Kaifeng HAN Xiaoyan XU Guiming WEI Wen TONG Peiying ZHU Jianglei MA Jun WANG Guangjian WANG Xueqiang YAN Jiying XIANG He HUANG Ruyue LI Xinhui WANG Yingmin WANG Shaohui SUN Shiqiang SUO Qiubin GAO Xin SU | 2022 | Science China(Information Sciences)2022，65，5： | 17 |
| 7 | Natural Variations at TIG1 Encoding a TCP Tran scription Factor Contribute to Plant Architecture Domestication in Rice显示文摘The modification of plant architecture is a crucial target in rice domestication and modern genetic improvement.Although several genes regulating rice plant architecture have been characterized,the molecular mechanisms underlying rice plant architecture domestication remain largely unclear.Here we show that the inclined tiller growth in wild rice is controlled by a single dominant gene,TILLER INCLINED GROWTH 1 (T/Gf),which is located on chromosome 8 and encodes a TCP transcriptional activator.TIG1 is primarily expressed in the adaxial side of the tiller base,promotes cell elongation,and enlarges the tiller angle in wild rice.Variations in the TIG1 promoter of indica cultivars {tig1 allele) resulted in decreased expression of TIG1 in the adaxial side of tiller base and reduced cell length and tiller angle,leading to the transition from inclined tiller growth in wild rice to erect tiller growth during rice domestication.TIG1 positively regulates the expression of EXP A3,EXPB5,and SAUR39 to promote cell elongation and increase the tiller angle.Selective sweep analysis revealed that the tig1 allele was selected in indica cultivars by human beings.The cloning and characterization of TIG1 supports a new scenario of plant architecture evolution in rice. | Weifeng Zhang Lubin Tan Hongying Sun Xinhui Zhao Fengxia Liu Hongwei Cai Yongcai Fu Xianyou Sun Ping Gu Zuofeng Zhu Chuanqing Sun | 2019 | Molecular Plant2019，12，8： | 13 |
| 8 | Comorbid Chronic Diseases and Acute Organ Injuries Are Strongly Correlated with Disease Severity and Mortality among COVID-19 Patients: A Systemic Review and Meta-Analysis显示文摘The recent outbreak of COVID-19 has been rapidly spreading on a global scale.To date,there is no specific vaccine against the causative virus,SARS-CoV-2,nor is there an effective medicine for treating COVID-19,thus raising concerns with respect to the effect of risk factors such as clinical course and pathophysiological parameters on disease severity and outcome in patients with COVID-19.By extracting and analyzing all available published clinical data,we identified several major clinical characteristics associated with increased disease severity and mortality among patients with COVID-19.Specifically,preexisting chronic conditions such as hypertension,cardiovascular disease,chronic kidney disease,and diabetes are strongly associated with an increased risk of developing severe COVID-19;surprisingly,however,we found no correlation between chronic liver disease and increased disease severity.In addition,we found that both acute cardiac injury and acute kidney injury are highly correlated with an increased risk of COVID-19-related mortality.Given the high risk of comorbidity and the high mortality rate associated with tissue damage,organ function should be monitored closely in patients diagnosed with COVID-19,and this approach should be included when establishing new guidelines for managing these high-risk patients.Moreover,additional clinical data are needed in order to determine whether a supportive therapy can help mitigate the development of severe,potentially fatal complications,and further studies are needed to identify the pathophysiology and the mechanism underlying this novel coronavirus-associated infectious disease.Taken together,these findings provide new insights regarding clinical strategies for improving the management and outcome of patients with COVID-19. | Xinhui Wang Xuexian Fang Zhaoxian Cai Xiaotian Wu Xiaotong Gao Junxia Min Fudi Wang | 2020 | Research2020，，1： | 13 |

| 10 | Interface issues of lithium metal anode for high-energy batteries: Challenges, strategies, and perspectives显示文摘Lithium(Li)metal is considered as one of the most promising anode materials for next-generation high-energy-density storage systems.However,the practical application of Li metal anode is hindered by interfacial instability and air instability due to the highly reactivity of Li metal.Unstable interface in Li metal batteries(LMBs)directly dictates Li dendrite growth,“dead Li”and low Coulombic efficiency,resulting in inferior electrochemical performance of LMBs and even safety issues.In addition,its sensitivity to ambient air leads to the severe corrosion of Li metal anode,high requirements of production and storage,and increased manufacturing cost.Plenty of efforts in recent years have overcome many bottlenecks in these fields and hastened the practical applications of high-energy-density LMBs.In this review,we focus on emerging methods of these two aspects to fulfill a stable and low cost electrode.In this perspective,design artificial solid electrolyte interphase(SEI)layers,construct three-dimensional conductive current collectors,optimize electrolytes,employ solid-state electrolytes,and modify separators are summarized to be propitious to ameliorate interfacial stability.Meanwhile,ex situ/in situ formed protective layers are highlighted in favor of heightening air stability.Finally,several possible directions for the future research on advanced Li metal anode are addressed. | Yiyao Han Bo Liu Zhen Xiao Wenkui Zhang Xiuli Wang Guoxiang Pan Yang Xia Xinhui Xia Jiangping Tu | 2021 | InfoMat2021，3，2： | 11 |
| 11 | Particle flters for probability hypothesis density flter with the presence of unknown measurement noise covariance显示文摘In Bayesian multi-target fltering,knowledge of measurement noise variance is very important.Signifcant mismatches in noise parameters will result in biased estimates.In this paper,a new particle flter for a probability hypothesis density(PHD)flter handling unknown measurement noise variances is proposed.The approach is based on marginalizing the unknown parameters out of the posterior distribution by using variational Bayesian(VB)methods.Moreover,the sequential Monte Carlo method is used to approximate the posterior intensity considering non-linear and non-Gaussian conditions.Unlike other particle flters for this challenging class of PHD flters,the proposed method can adaptively learn the unknown and time-varying noise variances while fltering.Simulation results show that the proposed method improves estimation accuracy in terms of both the number of targets and their states. | Wu Xinhui Huang Gaoming Gao Jun | 2013 | Chinese Journal of Aeronautics2013，26，6： | 9 |
| 12 | Revisiting Scientific Issues for Industrial Applications of Lithium–Sulfur Batteries显示文摘Inspired by high theoretical energy density(-2600 W h kg^(-1))and cost-effectiveness of sulfur cathode,lithium–sulfur batteries are receiving great attention and considered as one of the most promising next-generation high-energy-density batteries.However,over the past decades,the energy density and reliable safety levels as well as the commercial progress of lithium-sulfur batteries are still far from satisfactory due to the disconnection and huge gap between fundamental research and practical application. | Bo Liu Ruyi Fang Dong Xie Wenkui Zhang Hui Huang Yang Xia Xiuli Wang Xinhui Xia Jiangping Tu | 2018 | Energy & Environmental Materials2018，1，4： | 9 |
| 13 | Studies on Antiviral and Immuno-Regulation Activity of Low Molecular Weight Fucoidan from Laminaria japonica显示文摘The antiviral activity in vitro and in vivo and the effect of the immune system of two fucoidan fractions with low molecular weight and different sulfate content from Laminaria japonica(LMW fucoidans) were investigated in order to examine the possible mechanism. In vitro, I-type influenza virus, adenovirus and Parainfluenza virus I were used to infect Hep-2, Hela and MDCK cells, respectively. And 50% tissue culture infective dose was calculated to detect the antiviral activity of two LMW fucoidans. The results indicated that compared with the control group, 2 kinds of LMW fucoidans had remarkable antiviral activity in vitro in middle and high doses, while at low doses, the antiviral activity of 2 kinds of LMW fucoidans was not statistically different from that in the blank control group. And there was no statistically difference between two LMW fucoidans in antiviral activity. In vivo, LMW fucoidans could prolong the survival time of virus-infected mice, and could improve the lung index of virus-infected mice significantly, which have statistical differences with the control group significantly(p < 0.01). However, the survival time of the two LMW fucoidans was not statistically significant(p > 0.05). In this study, it was shown that both of two LMW fucoidans(LF1, LF2) could increase the thymus index, spleen index, phagocytic index, phagocytosis coefficient and half hemolysin value in middle and high doses, which suggested that LMW fucoidans could play an antiviral role by improving the quality of immune organs, improving immune cell phagocytosis and humoral immunity. | SUN Taohua ZHANG Xinhui MIAO Ying ZHOU Yang SHI Jie YAN Meixing CHEN Anjin | 2018 | Journal of Ocean University of China2018，17，3： | 8 |
| 14 | Identification of the state-space model and payload mass parameter of a flexible space manipulator using a recursive subspace tracking method显示文摘The on-orbit parameter identification of a space structure can be used for the modification of a system dynamics model and controller coefficients. This study focuses on the estimation of a system state-space model for a two-link space manipulator in the procedure of capturing an unknown object, and a recursive tracking approach based on the recursive predictor-based subspace identification(RPBSID) algorithm is proposed to identify the manipulator payload mass parameter. Structural rigid motion and elastic vibration are separated, and the dynamics model of the space manipulator is linearized at an arbitrary working point(i.e., a certain manipulator configuration).The state-space model is determined by using the RPBSID algorithm and matrix transformation. In addition, utilizing the identified system state-space model, the manipulator payload mass parameter is estimated by extracting the corresponding block matrix. In numerical simulations, the presented parameter identification method is implemented and compared with the classical algebraic algorithm and the recursive least squares method for different payload masses and manipulator configurations. Numerical results illustrate that the system state-space model and payload mass parameter of the two-link flexible space manipulator are effectively identified by the recursive subspace tracking method. | Zhiyu NI Jinguo LIU Zhigang WU Xinhui SHEN | 2019 | Chinese Journal of Aeronautics2019，32，2： | 8 |

| 16 | Phylogenetic pattern of alpine plants along latitude and longitude in Hengduan Mountains Region显示文摘To detect the horizontal pattern of phylogenetic structure shown by alpine plants, we measured phylogenetic structure using net related index(NRI) and net nearest taxon index(NTI), and analyzed the phylogenetic structure patterns of alpine plants along longitude, latitude and environmental gradients in the Hengduan Mountains Region(HDMR). Our results show that: 1) the phylogenetic structure tended to cluster with increasing latitude and longitude; 2) for NRI, latitude was closer related than longitude,while for NTI, longitude was closer related than latitude, though they both not significantly relate to NTI.The phylogenetic structure tended towards overdispersion in the southern HDMR, with good climate conditions of higher mean annual temperature and more mean annual precipitation. In contrast, with harsh climate conditions of lower mean annual temperature and less mean annual precipitation, the increasing environmental stress led to phylogenetic clustering in the northern HDMR. The results highlighted that in the alpine region of HDMR, environmental filters and geographical isolation had a great effect on the latitudinal and longitudinal alpine species distribution, respectively. | Xinhui Li Hang Sun | 2017 | Plant Diversity2017，39，1： | 8 |
| 17 | Recent progress on MOF-derived carbon materials for energy storage显示文摘Metal-organic frameworks(MOFs)are of quite a significance in the field of inorganic-organic hybrid crystals.Especially,MOFs have attracted increasing attention in recent years due to their large specific surface area,desirable electrical conductivity,controllable porosity,tunable geometric structure,and excellent thermal/chemical stability.Some recent studies have shown that carbon materials prepared by MOFs as precursors can retain the privileged structure of MOFs,such as large specific surface area and porous structure and,in contrast,realize in situ doping with heteroatoms(eg,N,S,P,and B).Moreover,by selecting appropriate MOF precursors,the composition and morphology of the carbon products can be easily adjusted.These remarkable structural advantages enable the great potential of MOF-derived carbon as high-performance energy materials,which to date have been applied in the fields of energy storage and conversion systems.In this review,we summarize the latest advances in MOF-derived carbon materials for energy storage applications.We first introduce the compositions,structures,and synthesis methods of MOF-derived carbon materials,and then discuss their applications and potentials in energy storage systems,including rechargeable lithium/sodium-ion batteries,lithium-sulfur batteries,supercapacitors,and so forth,in detail.Finally,we put forward our own perspectives on the future development of MOF-derived carbon materials. | Jincan Ren Yalan Huang He Zhu Binghao Zhang Hekang Zhu Shenghui Shen Guoqiang Tan Feng Wu Hao He Si Lan Xinhui Xia Qi Liu | 2020 | Carbon Energy2020，2，2： | 8 |
| 18 | Characteristics of dissolved organic matter in lakes with different eutrophic levels in southeastern Hubei Province,China显示文摘Dissolved organic matter(DOM)plays a crucial role in both the carbon cycle and geochemical cycles of other nutrient elements,which is of importance to the management and protection of the aquatic environments.To achieve a more comprehensive understanding the characteristics of DOM in the Changjiang(Yangtze)River basin,water samples from four natural lakes(Xiandao,Baoan,Daye,and Qingshan)in southeastern Hubei Province in China with different eutrophication levels were collected and analyzed.The optical characteristics were analyzed using ultraviolet-visible spectrophotometry and excitation-emission matrix spectroscopy coupled with parallel factor analysis.The results show that:(1)two humic-like components(C1 and C2)and two protein-like substances(C3 and C4)of DOM were identified in all waterbodies;(2)C3 originated primarily from the degradation of microalgae and contributed substantially to humic-like components during transformation.C4 was widely present in the Changjiang River basin and its formation was related to microbial activity,rather than algal blooms or seasons.Influenced by the water mixing,the protein-like components were more likely to be transformed by microorganism,whereas humic-like components were more easily to be photobleached;(3)the concentration of DOM and the fluorescence intensity of humic-like components gradually increased with rising lake eutrophication levels.With respect to protein-like components,only C3 showed changes along the eutrophication gradients;(4)DOM showed a high affinity with permanganate index(COD Mn)and chlorophyll a(chl a)while the relationship was variable with phosphorus.This study helps us systematically understand the DOM characteristics,microbial activities,and pollutant transformation in the Changjiang River basin and provides reference to the ecological restoration of aquatic environments. | Weixiang REN Xiaodong WU Xuguang GE Guiying LIN Mengdie ZHOU Zijie LONG Xinhui YU Wei TIAN | 2021 | Journal of Oceanology and Limnology2021，39，4： | 8 |
| 19 | Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species. | Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li | 2021 | Molecular Plant2021，14，6： | 8 |
| 20 | Water vapor δD dynamics over China derived from SCIAMACHY satellite measurements显示文摘This study investigates water vapor isotopic patterns and controls over China using high-quality water vapor δD data retrieved from the Scanning Imaging Absorption Spectrometer for Atmospheric Chartography(SCIAMACHY) observations.The results show that water vapor δD values on both annual and seasonal time-scales broadly exhibit a continental effect,with values largely decreasing northwestward from coastal lowlands to high-elevation mountainous regions.However,region-specific analysis reveals spatially distinct patterns of water vapor δD between seasons.In the monsoon domain(e.g.,China south of 35°N),depletion in D in the summer and fall seasons is closely tied to monsoon moisture sources(the Indian and Pacific oceans) and subsequent amount effect,but higher δD values in winter and spring are a result of isotopically-enriched continental-sourced moisture proceeded by less rainout.In contrast,farther inland in China(non-monsoon domain),moisture is derived overwhelmingly from the dry continental air masses and local evaporation,and δD values are largely controlled by the temperature effect,exhibiting a seasonality with isotopically enriched summer and depleted winter/spring.The observation that the spatial pattern of water vapor δD is the opposite to that of precipitation δD in the summer season also suggests that partial evaporation of falling raindrops is a key driver of water vapor isotope in the non-monsoon domain.This study highlights the importance of non-Rayleigh factors in governing water vapor isotope,and provides constraints on precipitation isotope interpretation and modern isotope hydrological processes over China. | LIU ZhongFang Kei YOSHIMURA Casey D.KENNEDY WANG XinHui PANG ShuoGuang | 2014 | Science China Earth Sciences2014，57，4： | 7 |
