| 2 | The first time observations of low-latitude ionospheric irregularities by VHF radar in Hainan显示文摘Sanya VHF radar (18.4°N, 109.6°E, dip latitude 12.8°N) at Hainan Island is the first coherent backscatter radar for sounding low-latitude ionospheric irregularities in the mainland of China. In this paper, we present the first results of low-latitude ionospheric E and F region irregularities using the radar data during the period from February 2009 to March 2010. The Doppler velocity of radar echoes from E region field aligned irregularities (FAIs) was about several tens of meters per second, while the Doppler spectral width was appreciably larger than the velocity, and could reach one hundred meters per second, indicating that the observed E region FAIs belonged to type 2 irregularities. The observations of range time intensity (RTI) maps of FAIs showed that E region irregularities most often occurred at night within the altitude range 85-115 km, and were rarely observed at afternoon hours. The percentage occurrence of E region FAIs maximized during spring months (Feb.-May) with a peak value over 80%. The heights at which the strongest echo related FAIs occurred were mainly around 100 km, lower than h'Es and the difference is mostly 10-20 km. December solstice seemed to be the minimum period of occurrence when the FAI echoes were commonly detected at a narrow altitude range 90-100 km. Moreover, simultaneous radar and GPS observations during spread F events in the pre-midnight hours of solar minimum revealed that significant GPS L band scintillations coincided with the appearance of F region plasma plume structures, which extended up to 450 km in altitude. | NING BaiQi HU LianHuan LI GuoZhu LIU LiBo WAN WeiXing | 2012 | Science China(Technological Sciences)2012，55，5： | 15 |
| 3 | Lane departure warning systems and lane line detection methods based on image processing and semantic segmentation:A review显示文摘Recently,the development and application of lane line departure warning systems have been in the market.For any of the systems,the key part of lane line tracking,lane line identification,or lane line departure warning is whether it can accurately and quickly detect lane lines.Since 1990 s,they have been studied and implemented for the situations defined by the good viewing conditions and the clear lane markings on road.After then,the accuracy for particular situations,the robustness for a wide range of scenarios,time efficiency and integration into higher-order tasks define visual lane line detection and tracking as a continuing research subject.At present,these kinds of lane marking line detection methods based on machine vision and image processing can be divided into two categories:the traditional image processing and semantic segmentation(includes deep learning)methods.The former mainly involves feature-based and model-based steps,and which can be classified into similarity-and discontinuity-based ones;and the model-based step includes different parametric straight line,curve or pattern models.The semantic segmentation includes different machine learning,neural network and deep learning methods,which is the new trend for the research and application of lane line departure warning systems.This paper describes and analyzes the lane line departure warning systems,image processing algorithms and semantic segmentation methods for lane line detection. | Weiwei Chen Weixing Wang Kevin Wang Zhaoying Li Huan Li Sheng Liu | 2020 | Journal of Traffic and Transportation Engineering(English Edition)2020，7，6： | 14 |
| 4 | Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool显示文摘Chang’E-4 landed in the South Pole-Aitken(SPA)basin,providing a unique chance to probe the composition of the lunar interior.Its landing site is located on ejecta strips in Von Karm´an crater that´possibly originate from the neighboring Finsen crater.A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations.In situ spectra of the regolith have peak band positions at 1 and 2μm,similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper,which confirms that the regolith’s composition of the landing area is mostly similar to that of Finsen ejecta.The rock spectrum shows similar band peak positions,but stronger absorptions,suggesting relatively fresh exposure.The rock may consist of 38.1±5.4%low-Ca pyroxene,13.9±5.1%olivine and 48.0±3.1%plagioclase,referred to as olivine-norite.The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle,but representative of the lunar lower crust.Alternatively,the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials.This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool,indicated by the fine to medium-sized texture(<3 mm)of the rock and the SPA-impact melting model[Icarus 2012;220:730–43]. | Honglei Lin Zhiping He Wei Yang Yangting Lin Rui Xu Chi Zhang Meng-Hua Zhu Rui Chang Jinhai Zhang Chunlai Li Hongyu Lin Yang Liu Sheng Gou Yong Wei Sen Hu Changbin Xue Jianfeng Yang Jie Zhong Xiaohui Fu Weixing Wan Yongliao Zou | 2020 | National Science Review2020，7，5： | 9 |
| 5 | Joint calibration algorithm for gain-phase and mutual coupling errors in uniform linear array显示文摘The effect of gain-phase perturbations and mutual coupling significantly degrades the performance of digital array radar(DAR). This paper investigates array calibration problems in the scenario where the true locations of auxiliary sources deviate from nominal values but the angle intervals are known. A practical algorithm is proposed to jointly calibrate gain-phase errors and mutual coupling errors. Firstly, a simplified model of the distortion matrix is developed based on its special structure in uniform linear array(ULA). Then the model is employed to derive the precise locations of the auxiliary sources by one-dimension search. Finally, the least-squares estimation of the distortion matrix is obtained. The algorithm has the potential of achieving considerable improvement in calibration accuracy due to the reduction of unknown parameters. In addition,the algorithm is feasible for practical applications, since it requires only one auxiliary source with the help of rotation platforms. Simulation results demonstrate the validity, robustness and high performance of the proposed algorithm. Experiments were carried out using an S-band DAR test-bed.The results of measured data show that the proposed algorithm is practical and effective in application. | Li Weixing Lin Jianzhi Zhang Yue Chen Zengping | 2016 | Chinese Journal of Aeronautics2016，29，4： | 9 |

| 7 | Sediment pollution characteristics and in situ control in a deep drinking water reservoir显示文摘Sediment pollution characteristics, in situ sediment release potential, and in situ inhibition of sediment release were investigated in a drinking water reservoir. Results showed that organic carbon(OC), total nitrogen(TN), and total phosphorus(TP) in sediments increased from the reservoir mouth to the main reservoir. Fraction analysis indicated that nitrogen in ion exchangeable form and Na OH-extractable P(Fe/Al-P) accounted for 43% and 26% of TN and TP in sediments of the main reservoir. The Risk Assessment Code for metal elements showed that Fe and Mn posed high to very high risk. The results of the in situ reactor experiment in the main reservoir showed the same trends as those observed in the natural state of the reservoir in 2011 and 2012; the maximum concentrations of total OC, TN, TP, Fe,and Mn reached 4.42 mg/L, 3.33 mg/L, 0.22 mg/L, 2.56 mg/L, and 0.61 mg/L, respectively. An in situ sediment release inhibition technology, the water-lifting aerator, was utilized in the reservoir. The results of operating the water-lifting aerator indicated that sediment release was successfully inhibited and that OC, TN, TP, Fe, and Mn in surface sediment could be reduced by 13.25%, 15.23%, 14.10%, 5.32%, and 3.94%, respectively. | Zizhen Zhou Tinglin Huang Yang Li Weixing Ma Shilei Zhou Shenghai Long | 2017 | Journal of Environmental Sciences2017，29，2： | 6 |

| 9 | Hybrid interference alignment and power allocation for multi-user interference MIMO channels显示文摘This paper proposes a hybrid interference alignment scheme which combines maximizing signal-toleakage-noise ratio(Max-SLNR) at transmitter and maximizing signal-to-interference-noise ratio(Max-SINR) at receiver.The proposed scheme gives the same sum rate as the existing method using Max-SINR at both transmitter and receiver by avoiding the operation of reversing channel,thus it provides a simpler solution.Furthermore,two power allocation procedures are devised based on game theory and water filling.The gain of these schemes over equal power allocation increases to 2 bit/s/Hz in correlated fading channels as large-scale fading becomes significant.Additionally,user fairness is solved by introducing weighting factors. | SHU Feng YOU XiaoHu WANG Mao HAN YuBing LI Yang SHENG WeiXing | 2013 | Science China(Information Sciences)2013，56，4： | 5 |
| 10 | Ultra-stable super-resolution fluorescence cryo-microscopy for correlative light and electron cryo-microscopy显示文摘Remarkable progress in correlative light and electron cryo-microscopy(cryo-CLEM) has been made in the past decade. A crucial component for cryo-CLEM is a dedicated cryo-fluorescence microscope(cryo-FM). Here, we describe an ultra-stable superresolution cryo-FM that exhibits excellent thermal and mechanical stability. The temperature fluctuations in 10 h are less than0.06 K, and the mechanical drift over 5 h is less than 200 nm in three dimensions. We have demonstrated the super-resolution imaging capability of this system(average single molecule localization accuracy of ~13.0 nm). The results suggest that our system is particularly suitable for long-term observations, such as single molecule localization microscopy(SMLM) and cryogenic super-resolution correlative light and electron microscopy(csCLEM). | Xiaojun Xu Yanhong Xue Buyun Tian Fengping Feng Lusheng Gu Weixing Li Wei Ji Tao Xu | 2018 | Science China(Life Sciences)2018，61，11： | 3 |
| 11 | An executable modeling and analyzing approach to C4ISR architecture显示文摘To analyze the behavioral model of the command,control,communication,computer,intelligence,surveillance,reconnaissance(C4ISR)architecture,we propose an executable modeling and analyzing approach to it.First,the meta concept model of the C4ISR architecture is introduced.According to the meta concept model,we construct the executable meta models of the C4ISR architecture by extending the meta models of fUML.Then,we define the concrete syntax and executable activity algebra(EAA)semantics for executable models.The semantics functions are introduced to translating the syntax description of executable models into the item of EAA.To support the execution of models,we propose the executable rules which are the structural operational semantics of EAA.Finally,an area air defense of the C4ISR system is used to illustrate the feasibility of the approach. | HE Hongyue ZHU Weixing LI Ruiyang DENG Qiaoyu | 2020 | Journal of Systems Engineering and Electronics2020，31，1： | 3 |

| 13 | Preliminary experimental results by the prototype of Sanya Incoherent Scatter Radar显示文摘In the past decades,the Incoherent Scatter Radar(ISR)has been demonstrated to be one of the most powerful instruments for ionosphere monitoring.The Institute of Geology and Geophysics at the Chinese Academy of Sciences was founded to build a state-ofthe-art phased-array ISR at Sanya(18.3°N,109.6°E),a low-latitude station on Hainan Island,named the Sanya ISR(SYISR).As a first step,a prototype radar system consisting of eight subarrays(SYISR-8)was built to reduce the technical risk of producing the entire large array.In this work,we have summarized the preliminary experimental results based on the SYISR-8.The amplitude and phase among 256 channels were first calibrated through an embedded internal monitoring network.The mean oscillation of the amplitude and phase after calibration were about 1 dB and 5°,respectively,which met the basic requirements.The beam directivity was confirmed by crossing screen of the International Space Station.The SYISR-8 was further used to detect the tropospheric wind profile and meteors.The derived winds were evaluated by comparison with independent radiosonde and balloon-based GPS measurements.The SYISR-8 was able to observe several typical meteor echoes,such as the meteor head echo,range-spread trail echo,and specular trail echo.These results confirmed the validity and reliability of the SYISR-8 system,thereby reducing the technical risk of producing the entire large array of the SYISR to some extent. | XinAn Yue WeiXing Wan Han Xiao LingQi Zeng ChangHai Ke BaiQi Ning Feng Ding BiQiang Zhao Lin Jin Chen Li MingYuan Li JunYi Wang HongLian Hao Ning Zhang | 2020 | Earth and Planetary Physics2020，4，6： | 3 |
| 14 | Destratification and oxygenation efficiency of a water-lifting aerator system in a deep reservoir:Implications for optimal operation显示文摘Thermal stratification is a common phenomenon in lakes and reservoirs and has a significant influence on water quality dynamics.Heihe Reservoir is a canyon-shaped reservoir in Shaanxi Province with strong thermal stratification.Therefore,eight water-lifting aerators(WLAs) were installed in this reservoir,which could overcome thermal stratification and increase oxygenation with gas flows between 20 and 50 m3/hr,and oxygenate the hypolimnion with gas flows less than 20 m3/hr.To examine the destratification efficiency of the WLA system,we used a threedimensional hydrodynamic module based on MIKE 3 to simulate the thermal structure of Heihe Reservoir and compared the simulations with measured data.Results showed that operation of the WLA system promoted water mixing and effectively oxygenated the hypolimnion.Through the established energy utilization assessment method,the energy utilization efficiency of the WLA system was between 5.36% and 7.30%,indicating the capability of the technique for destratification in such a large reservoir.When the surface water temperature dropped to the theoretical mixed water temperature calculated by the energy utilization assessment method,reducing gas flow could save energy.This would prevent anaerobic conditions from occurring in the bottom water and maintain good water quality in Heihe Reservoir. | Yang Li Tinglin Huang Xinlin Tan Zizhen Zhou Weixing Ma | 2018 | Journal of Environmental Sciences2018，30，11： | 3 |
| 15 | The payloads of planetary physics research onboard China’s First Mars Mission (Tianwen-1)显示文摘Mars is not only our nearby but also the most Earth-like planetary neighbor.Scientific exploration of Mars is thus of crucial value to our understanding of the solar system.The existence of abundant evidence for the former presence of water on Mars demands further exploration for signs of life on our sister planet,and investigations that could shed light on conditions favorable to the origin of life.For nearly 60 years,humans have conducted orbitally-based remote sensing and in-situ surface exploration of Mars,leading to many significant scientific discoveries.But much remains to be done before we can be sure that we truly and fully understand Mars.Key research topics include the history of water on Mars and how that history relates to the planet’s habitable environment-past,present,and future;the distribution and evolution of waterbearing and evaporative salt minerals on the planet’s surface;the history of volcanic activity on Mars;the Martian magnetic field and its effect on the escape of water and atmosphere from the planet;interactions between the solar wind and the Martian atmosphere and ionosphere;atmospheric characteristics and climate change on Mars;and so on(Li CL et al.,2018;Liu JJ et al.,2018).Based on the above scientific questions about life,climate,and geology on Mars,the international planetary science community has formulated ambitious Mars exploration programs. | WeiXing Wan Chi Wang ChunLai Li Yong Wei JianJun Liu | 2020 | Earth and Planetary Physics2020，4，4： | 3 |
| 16 | First results of optical meteor and meteor trail irregularity from simultaneous Sanya radar and video observations显示文摘Meteoroids entering the Earth's atmosphere can create meteor trail irregularity seriously disturbing the background ionosphere. Although numerous observations of meteor trail irregularities were performed with VHF/UHF coherent scatter radars in the past, no simultaneous radar and optical instruments were employed to investigate the characteristics of meteor trail irregularity and its corresponding meteoroid. By installing multiple video cameras near the Sanya VHF radar site, an observational campaign was conducted during the period from November 2016 to February 2017. A total of 242 optical meteors with simultaneous non-specular echoes backscattered from the plasma irregularities generated in the corresponding meteor trails were identified. A good agreement between the angular positions of non-specular echoes derived from the Sanya radar interferometer and those of optical meteors was found,validating that the radar system phase offsets have been properly calibrated. The results also verify the interferometry capability of Sanya radar for meteor trail irregularity observation. The non-specular echoes with simultaneous optical meteors were detected at magnetic aspect angles greater than ~78°. Based on the meteor visual magnitude estimated from the optical data, it was found that the radar nonspecular echoes corresponding to brighter meteors survived for longer duration. This could provide observational evidence for the significance of meteoroid mass on the duration of meteor trail irregularity. On the other hand, the simultaneous radar and video common-volume observations showed that there were some cases with optical meteors but without radar non-specular echoes. One possibility could be that some of the optical meteors appeared at extremely low altitudes where meteor trail irregularities rarely occur. | GuoZhu Li BaiQi Ning Ao Li SiPeng Yang XiuKuan Zhao BiQiang Zhao WeiXing Wan | 2018 | Earth and Planetary Physics2018，2，1： | 3 |
| 17 | Physiological and Transcriptomic Changes During Autumn Coloration and Senescence in Ginkgo biloba Leaves显示文摘Autumn leaf senescence and coloration is a complex process and a striking natural phenomenon.Here,through biology approach integrating transcriptomic analyses in Ginkgo biloba,we determined that the content of chlorophyll decreased during leaf senescence,while carotenoid components increased until late October in the turning stage(TS)and then decreased in the yellow leaf stage(YS).Simultaneously,chlorophyll biosynthesis genes exhibited significantly lower expression levels while chlorophyll degradation genes showed increased expression from the green leaf stage(GS)to YS.However,carotenoid biosynthesis-related genes showed enhanced expression,especially in TS.An analysis of the expression of genes related to senescence demonstrated that the expression levels of most abscisic acid-and jasmonic acid-related genes,autophagy,WRKY,and NAC genes increased,whereas cytoskeleton-,photosynthesis-,and antioxidation-related genes decreased from GS to YS.Furthermore,G.biloba seedlings exogenously treated with abscisic acid,jasmonic acid,or ultraviolet-B radiation all showed obvious color variation and senescence symptoms.We used these exogenously seedlings to further validate the function of several genes involved in chlorophyll biosynthesis and senescence.Taken together,these results contribute to the elucidation of the molecular mechanisms of leaf coloration and senescence in G.biloba as well as in the identification of candidate genes involved in this process. | Weixing Li Lu Wang Zhichong He Zhaogeng Lu Jiawen Cui Ningtao Xu Biao Jin Li Wang | 2020 | Horticultural Plant Journal2020，6，6： | 3 |
| 18 | Trifolirhizin induces autophagy-dependent apoptosis in colon cancer via AMPK/mTOR signaling显示文摘Dear Editor,Colorectal cancer(CRC)is one of the most frequent diseases with high mortality around the world.Conventional treatments of CRC remain unsatisfactory due to the increasing recurrence rate and adverse reactions including neutropenia,drug resistance,etc.Recently,autophagy has been shown to be involved in regulating cancer development and progression by regulating apoptosis through pro-apoptosis proteins including caspases,in addition to being a potential target for cancer therapeutic intervention.1 Trifolirhizin(Supplementary Fig.S1a)is a natural flavonoid glycosides isolated from Sophora flavescens as well as a bioactive constituent of Xian-Lian-Ke-Li,a commercial traditional Chinese medicine for the cancer prevention.Numerous evidence manifested that trifolirhizin inhibited proliferative activity in melanoma B16 cell,lung cancer H23 cell,human ovarian A2780 cell,and human gastric cancer cell MKN45.2 However,its pharmacological effect and mechanism on CRC remain elusive.Herein,we evaluated the effect of trifolirhizin on autophagy and apoptosis on CRC as well as its related mechanisms,in order to provide evidence to develop a potential agent with less adverse effect in treating CRC. | Dongdong Sun Weiwei Tao Feng Zhang Weixing Shen Jiani Tan Liu Li Qinghai Meng Yugen Chen Ye Yang Haibo Cheng | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 3 |
| 19 | CFD simulation of flow field and resistance in a 19-core tandem ceramic membrane module显示文摘CFD simulation of the permeation process of a 19-core tandem ceramic membrane module was established to investigate flow field and resistance and its change in permeate flux to the membrane element position and the channel of each membrane element.The results show that when the volume flow rate changes from26 m3·h-1 to 89 m3·h-1,the resistance of each part of the membrane module increases gradually.The increase in resistance loss in the membrane element is faster than the plates and the bell mouths.In a single ceramic membrane module,the maximum difference in flow rate of each membrane tube is 7.23%.In a single membrane tube,the outer ring channels 3–5,3–6,3–7,3–8 are relatively slow.The maximum mass flow deviation from the mean is 2.7%.This work helps to clarify the flow mechanism within the modules,optimize the structure of the equipment and provide a reliable basis for the improvement of industrial ceramic membrane modules. | Yujia Tong Lukuan Huang Weixing Li | 2020 | Chinese Journal of Chemical Engineering2020，28，3： | 2 |
| 20 | Cytological and Proteomic Analysis of Ginkgo biloba Pollen Intine显示文摘The pollen intine plays important roles in pollen germination and tube growth,but related information in Ginkgo biloba remains unclear.We isolated and obtained de-exined pollen from G.biloba.Using fluorescent probes,we observed the strongest cellulose fluorescence in the pollen intine.De-esterified pectin immunolabeled with JIM5 was present throughout the entire cell wall,whereas esterified pectin recognized by the monoclonal antibody JIM7 was concentrated in some regions.Callose staining with aniline blue was observed across the entire surface of the pollen intine.These results were confirmed by Fourier Transform InfraRed(FTIR)analysis.We also used proteomic approaches to identify different proteins between mature and de-exined pollen(48h after hydration)in vitro.Based on mass spectrometry,de-exined pollen had more proteins than mature pollen,including calmodulin,serine hydroxymethyltransferase,β-galactosidase 6,and class IV chitinase.According to Gene Ontology(GO)analysis,the differentially expressed proteins were mainly associated with transportation,defense reaction,sugar metabolism,energy metabolism,signal transduction,and cell wall formation.These findings suggest that most proteins involved in pollen germination and pollen tube growth are synthesized during pollen hydration,indicating the important role of pollen hydration in the reproductive process of G.Biloba. | Weixing Li Yunling Ye Fangmei Cheng Yan Lu Biao Jin Li Wang | 2020 | Horticultural Plant Journal2020，6，4： | 2 |
