1Tunnel seismic tomography method for geological prediction and its application显示文摘隧道的典型存在方法地质的预言因为这种技术国内外在开发中,包括否定明显的速度,水平地震侧面,和隧道地震预言(TSP ) 方法。就更简单的观察方法并且数据处理而言,它是难的精确地在隧道脸的前面决定墙岩石的地震速度。因此,使用这些有缺点的方法可以导致不为分类墙岩石特征提供足够的证据的不精密的地质的推论。这篇论文用空间观察安排和移植和处理解决在隧道脸的前面分析墙岩石的速度结构的问题并且认识到隧道墙岩石的地质的框架的精确成像的旅行时间倒置图象建议隧道地震断层摄影术(TST ) 方法。这个方法为在复杂地质的条件下面的地质的预言是很适当的。Zhao Yonggui Jiang Hui Zhao Xiaopeng 2006Applied Geophysics2006,3,2:50

3The Current Situation on Major Depressive Disorder in China:Research on Mechanisms and Clinical Practice显示文摘Depression is the most disabling disorder worldwide that accounts for the highest proportion of global burden attributable to mental disorders. Major depressive disorder(MDD) is characterized by deep sadness, reduced energy,vegetative nervous system dysregulation, cognitive dysfunction, and even a high suicidal tendency. Although other treatment choices are available, antidepressant medication is the front-line treatment option for MDD. Regarding clinical efficacy, only ~50% of patients respond to frontline antidepressants, and <33% obtain remission. Currently, objective indexes to guide clinical decisions are still lacking. Furthermore, knowledge about the neurobiological mechanisms underlying discrepant antidepressant outcomes is still also fragmentary. In the present review, we discuss the current research progress and clinical opinions on MDD in China.Zhenghua Hou Wenhao Jiang Yingying Yin Zhijun Zhang Yonggui Yuan 2016Neuroscience Bulletin2016,32,4:16
4The uptake diversity of soil nitrogen nutrients by main plant species in Kobresia humilis alpine meadow on the Qinghai-Tibet Plateau显示文摘We studied the uptake of ammonium,nitrate,and a variety of amino acids by alpine plant species in the Kobresia humilis alpine meadow ecosystem in situ.We examined the extent of niche separation in uptake of N source by different plant species in alpine communities,and investigated the contribution of symbiotically fixed N to the total N in alpine meadow.The results are(1) δ 15 N natural abundance values of 13 plant species lie between 2.680‰ and 5.169‰,and the scope is 7.849‰.(2) Leguminous plants,such as Trigonella ruthenica,Gueldenstaedtia diversiffolia,and Oxytyopis ochrocephala,and non-leguminous plant Gentiana straminea uptake low amounts of 15 N labeled ammonium,nitrate,glycine or aspartate in soil.(3) As far as the plant uptake of organic N is concerned,Kobresia humilis,Poa pratensis,and Gentiuna spathutifolta can effectively uptake organic nitrogen,and about 37%-40% of the nitrogen of these species comes from soil organic nitrogen sources(such as glycine and aspartate).Stipa aliena can effectively uptake nitrate,and 60% of its nitrogen comes from soil nitrate.Potentilla anserina,Poa pratensis,and Thalictrum alpinum can effectively absorb ammonium in comparason to other plant species in the meadow,and about 25%-27% of the nitrogen in these plants comes from soil ammonium.(4) The contribution of leguminous fixed N to total N is 7.48%-9.26% in Kobresia humilis alpine meadow.(5) These data show many plant species of alpine meadow may effectively utilize dissolved organic nitrogen such as amino acids,and these plants have diverse ways to uptake soil nitrogen in alpine meadows.Based on the results we can partly explain why there are abundant biodiversities and how plants at alpine habitat utilize the limited soil N sources.WANG WenYing MA YongGui XU Jin WANG HuiChun ZHU JinFu ZHOU HuaKun 2012Science China Earth Sciences2012,55,10:13

6Variability in the composition and export of silica in the Huanghe River Basin显示文摘Concentrations of suspended particle material(SPM), dissolved silicate(DSi), biogenic silica(BSi), phytoliths(plant produced siliceous microscopic structures), and other parameters were analyzed to examine the influence of both natural processes and human activities on silica delivery to the estuary of the Huanghe River(Yellow River). Our results indicate that the concentrations of DSi in the river decreased significantly since 1986. Approximately 34% of dissolved silica was trapped in the basin between 1986 and 2010 due to a reduction of soil erosion. Phytoliths comprised 67.2%–96.3% of BSi, with the smoothing bar type being the dominant form. Concentrations of BSi are significantly higher in the Huanghe River compared to other major rivers throughout the world due to its high sediment yield. We also found that the ratios of BSi/(BSi+DSi) and BSi/SPM were approximately 0.5 and 0.003 at Lijin near the river mouth, indicating that BSi carried in suspension by the Huanghe River was an important component of the rivers silica load. Significant amounts of BSi were also composed of phytoliths in Bohai Sea sediments near the Huanghe River estuary with the smoothing bar form again being the most abundant. The relatively high specific fluxes of BSi in the Huanghe River reflect its high turbidity and high erosion rates in the basin. The high sediment load originating on the Loess Plateau is likely responsible for the higher BSi flux, in agreement with a general trend of increasing BSi flux with increasing sediment flux in global river systems. This study demonstrates that BSi transported by rivers can be composed largely of phytoliths originating from the erosion of topsoils. The flux of phytoliths in river's suspended sediment load may therefore represent a significant contribution to the biogeochemical cycle of silica in coastal waters.RAN XiangBin CHE Hong ZANG JiaYe YU YongGui LIU Sen ZHENG LiLi 2015Science China Earth Sciences2015,58,11:7
7Energy-balanced multiple-sensor collaborative scheduling for maneuvering target tracking in wireless sensor networks显示文摘An energy-balanced multiple-sensor collaborative scheduling is proposed for maneuvering target tracking in wireless sensor networks (WSNs). According to the position of the maneuvering target, some sensor nodes in WSNs are awakened to form a sensor cluster for target tracking collaboratively. In the cluster, the cluster head node is selected to implement tracking task with changed sampling interval. The distributed interactive multiple model (IMM) filter is employed to estimate the target state. The estimation accuracy is improved by collaboration and measurement information fusion of the tasking nodes. The balanced distribution model of energy in WSNs is constructed to prolong the lifetime of the whole network. In addition, the communication energy and computation resource are saved by adaptively changed sampling intervals, and the real-time performance is satisfactory. The simulation results show that the estimation accuracy of the proposed scheme is improved compared with the nearest sensor scheduling scheme (NSSS) and adaptive sensor scheduling scheme (ASSS). Under satisfactory estimation accuracy, it has better performance in saving energy and energy balance than the dynamic collaborative scheduling scheme (DCSS).Liu, Yonggui Xu, Bugong Feng, Linfang 2011控制理论与应用(英文版)2011,9,1:7
8Development of image-based wheat spike counter through a Faster R-CNN algorithm and application for genetic studies显示文摘Spike number(SN) per unit area is one of the major determinants of grain yield in wheat. Development of high-throughput techniques to count SN from large populations enables rapid and cost-effective selection and facilitates genetic studies. In the present study, we used a deep-learning algorithm, i.e., Faster Region-based Convolutional Neural Networks(Faster R-CNN) on Red-Green-Blue(RGB) images to explore the possibility of image-based detection of SN and its application to identify the loci underlying SN. A doubled haploid population of 101 lines derived from the Yangmai 16/Zhongmai 895 cross was grown at two sites for SN phenotyping and genotyped using the high-density wheat 660 K SNP array.Analysis of manual spike number(MSN) in the field, image-based spike number(ISN), and verification of spike number(VSN) by Faster R-CNN revealed significant variation(P < 0.001) among genotypes, with high heritability ranged from 0.71 to 0.96. The coefficients of determination(R^(2)) between ISN and VSN was 0.83, which was higher than that between ISN and MSN(R^(2)= 0.51), and between VSN and MSN(R^(2)= 0.50). Results showed that VSN data can effectively predict wheat spikes with an average accuracy of 86.7% when validated using MSN data. Three QTL Qsnyz.caas-4 DS, Qsnyz.caas-7 DS, and QSnyz.caas-7 DL were identified based on MSN, ISN and VSN data, while QSnyz.caas-7 DS was detected in all the three data sets. These results indicate that using Faster R-CNN model for image-based identification of SN per unit area is a precise and rapid phenotyping method, which can be used for genetic studies of SN in wheat.Lei Li Muhammad Adeel Hassan Shurong Yang Furong Jing Mengjiao Yang Awais Rasheed Jiankang Wang Xianchun Xia Zhonghu He Yonggui Xiao 2022The Crop Journal2022,10,5:5

10Lodging resistance and yield potential of winter wheat:effect of planting density and genotype显示文摘Improved lodging resistance is important for achieving high yield in irrigated environments.This study was conducted to determine genotypic variation in lodging resistance and related morphological traits among winter wheat cultivars planted at two densities,and to identify key traits associated with lodging resistance.Lodging performance of 28 genotypes,including 24 released cultivars and four advanced lines,was evaluated at 250 plants per square meter and 500 plants per square meter in Shandong province during the 2008–2009 and 2009–2010 crop seasons.At the higher density,the average grain yield was 2.6%higher,even though lodging score rose by as much as 136%.The higher planting density increased lodging through increased leaf area index(LAI),plant height,center of gravity and length of basal internodes,and reduced grain weight per spike and diameter of the lower two stem internodes.LAI,center of gravity and diameter of first internodes,as the important indicators for lodging resistance,were significantly correlated with lodging score,with R=0.62,0.59 and–0.52(P<0.01),respectively.Plant pushing resistance was significantly associated with diameter and length of the first internodes(R=0.71–0.77,P<0.01),indicating it could be used to assess the strength of the lower stem.Higher planting density could be used to select genotypes with lodging resistance in irrigated environments.Cultivars carrying high plant density tolerance and high yield potential,such as Jimai 22 and Liangxing 66,were recommended as leading cultivars for production as well as elite crossing parents for further increasing yield potential in the Yellow and Huai Valleys Winter Wheat Zone in China.Yonggui XIAO Jianjun LIU Haosheng LI Xinyou CAO Xianchun XIA Zhonghu HE 2015Frontiers of Agricultural Science and Engineering2015,2,2:5

12The influence of atmospheric Hg on Hg contaminations in rice and paddy soil in the Xunyang Hg mining district,China显示文摘To date, the Xunyang mercury(Hg) mining district is the only ongoing large-scale Hg mining district in China. To understand the influence of Hg contamination mode from the Hg mining and smelting activities, 27 sampling sites in the Xunyang Hg mining district were chosen in this study. Total gaseous mercury(TGM) in ambient air was measured using a Lumex-RA915 automatic Hg analyzer in2011. Rice samples and soil samples from rhizosphere were collected systematically and simultaneously. Total Hg(THg) and methylmercury(Me Hg) concentrations in rice grain and soil samples and Hg speciation with modified sequential selective extractions were measured. The local environment was seriously polluted with Hg. The TGM(302 ± 376 ng·m-3, ranging from 24 to 2220 ng·m^(-3)) in the local ambient air, THg(28 ± 30 mg·kg^(-1), ranging from 0.31 to 121 mg·kg^(-1)) and Me Hg(2.3 ± 1.9 lg·kg^(-1),ranging from 0.24 to 8.9 lg·kg^(-1)) in soil samples were at the sample level with Hg contaminated area. The THg concentration(26 ± 16 lg·kg^(-1)ranging from 4.5 to 71 lg·kg^(-1)) in most of the rice grain samples clearly exceeds the threshold level(20 lg·kg^(-1)) in the Chinese national guidelines for cereals(NY 861-2004). The inorganic mercury(IHg)(9.1 ± 5.6 lg·kg^(-1), ranging from 1.2 to 24 lg·kg^(-1)) and Me Hg(14 ± 9.8 lg·kg^(-1), ranging from 2.1 to 59 lg·kg^(-1))concentration in rice grain samples were at the same level with Hg contaminated area. The main species of Hg in paddy soils reveal strong complex Hg and residue Hg. According to the correlation analysis, a Hg pollution mode from local Hg mining and smelting was hypothesized, including Hg emission, transportation, methylation, and uptake process.Ming Ao Bo Meng Atindra Sapkota Yonggui Wu Xiaoli Qian Guangle Qiu Shunqing Zhong Lihai Shang 2017Acta Geochimica2017,36,2:5

14Enrichment of heavy metals in coal gangue by puff balls and mechanism research显示文摘Coal gangue with/without wild puff balls growing on or covering up were analyzed by means of inductively coupled plasma atomic emission spectrometry(ICP-AES) and atomic fluorescence spectrometry(AFS) to detect the contents of heavy metal elements in the plants. Seven heavy metals were chosen to do the experiments, which showed that the puff balls have strong enrichment capacity for heavy metals(As, Pb, Mn and Ni). The highest enrichment level was Mn, 220.3 mg/kg(dry weight) for puffball fruiting bodies, and the highest As, Cr and Pb enrichment levels for puffball mycelium were 111, 265.3 and 86 mg/kg, respectively. Cd, Mn and Ni could transfer from puffball mycelium to its fruiting bodies, while As, Cr, Pb and Co mainly accumulated in the mycelium. The contents of five organic acids(tartaric acid, glycolic acid, lactic acid, citric acid and malic acid) in puffballs were determined with high performance liquid chromatography. With water, ethanol and ethyl acetate as solvents, the puffball extracts performed dissolution reactions with coal gangue, in which the water extract(containing a large amount of organic acids) was most effective in releasing heavy metals, especially As, Pb, Cr, Mn, Co and Ni from coal gangue. As a pioneer species, puff balls absorbed the hazardous trace elements in coal gangue matrix to reduce its eco-toxicity, on the other hand, it raised the p H value of coal gangue, improving the vegetation growing conditions for coal gangue matrix to a certain extent and laying the foundation for ecological restoration of coal gangue dumps.CHEN Miao ZHU Lijun WU Yonggui FU Tianling RAN Yan 2014Chinese Journal Of Geochemistry2014,33,4:4

16A novel intelligent verification platform based on a structured analysis model显示文摘An intelligent verification platform based on a structured analysis model is presented.Using an abstract model mechanism with specific signal interfaces for user callback,the unified structured analysis data,shared by the electronic system level design,functional verification,and performance evaluation,enables efficient management review,auto-generation of code,and modeling in the transaction level.We introduce the class tree,flow parameter diagram,structured flow chart,and event-driven finite state machine as structured analysis models.As a sand table to carry maps from different perspectives and levels via an engine,this highly reusable platform provides the mapping topology to search for unintended consequences and the graph theory for comprehensive coverage and smart test cases.Experimental results show that the engine generates efficient test sequences,with a sharp increase in coverage for the same vector count compared with a random test.XIE Zheng WANG XinAn LIAN ZhiBin LUO YongGui HU ZiYi 2013Science China(Information Sciences)2013,56,6:4
17Validation of hyperintense middle cerebral artery sign in acute ischemic stroke Comparison between magnetic resonance imaging and angiography显示文摘We performed a retrospective analysis of non-contrast computed tomography (CT) scans, immediately subsequent magnetic resonance imaging (MRI), and cerebral angiography data from 30 consecutive patients with acute ischemic stroke within 6 hours after symptom onset. Results showed that eleven patients developed subsequent hemorrhagic transformation at follow-up. A hyperintense middle cerebral artery sign on MRI was found in six hemorrhagic patients, all of who had acute thrombosis formation on magnetic resonance angiography and digital subtraction angiography. No patients in the non-hemorrhagic group had hyperintense middle cerebral artery sign on MRI. The sensitivity, specificity, and positive predictive values of the hyperintense middle cerebral artery sign on MRI T1-weighted image for subsequent hemorrhagic transformation were 54.5%, 100%, and 100% respectively. Hyperdense middle cerebral artery sign on non-contrast CT was observed in nine patients, five of who developed hemorrhagic transformation. These data suggest that hyperintense middle cerebral artery sign on MRI T1-weighted image is a highly specific and moderately sensitive indicator of subsequent hemorrhagic transformation in patients after acute ischemic stroke, and its specificity is superior to CT.Gang Guo Yonggui Yang Weiqun Yang 2012Neural Regeneration Research2012,7,3:4
18Efficacy and safety of anlotinib plus S-1as thirdly-line or later-line treatmentin advanced non-small cell lung cancer显示文摘Objective Anlotinib,an oral vascular endothelial growth factor receptor 2(VEGFR2)inhibitor,has confirmed antitumor activity in lung cancer in both in vitro and in vivo assays,and has been recommended as third-line treatment agent in non-oncogene driven non-small cell lung cancer(NSCLC).This prospective study aimed to investigate the efficacy and safety of anlotinib plus S-1 for third-or later-line treatment in patients with advanced NSCLC.Methods Patients with histologically or cytologically confirmed NSCLC,and documented disease progression following second-line chemotherapy,and/or epidermal growth factor receptor-tyrosine kinase inhibitor(EGFR-TKI)treatment were enrolled in this study.The patients were treated anlotinib(8 mg daily d 1–14)and S-1(60 mg/m^2 d 1–14)and the treatment was repeated every 3 weeks.Treatment was continued until disease progression or unacceptable toxicity occurred.The objective response rate(ORR),disease control rate(DCR),progression-free survival(PFS),and adverse events(AEs)were reviewed and evaluated.Results Forty-one patients were enrolled in the study between June 2018 and December 2018.The total ORR and DCR were 26.8%and 80.5%,respectively.The median PFS was 5.2 months[95%confidence interval(CI),3.9 to 6.6 months].In the univariate analysis,there was a significant difference in the median PFS between patients with brain metastases and those without brain metastases(4.8 months vs 5.9 months,respectively;P=0.039).The Eastern Cooperative Oncology Group(ECOG)performance status(P=0.002),lines of therapy(P=0.015),and therapeutic evaluation(P=0.014)were independent factors that influenced PFS.The most common AEs were hypertension,proteinuria,myelosuppression,gastrointestinal reactions,fatigue,and mucositis.Conclusion Anlotinib plus S-1 is an effective and safe regimen for advanced NSCLC as third-or later-line therapy.Heng Cao Kai Liang Peng Liu Jing Wang Yuanyuan Ji Lujuan Xu Weilong Wu Shengnan Guo Xuekun Song Yonggui Hong 2020Oncology and Translational Medicine2020,6,1:4
