| 1 | Path planning for mobile robot using self-adaptive learning particle swarm optimization显示文摘As a challenging optimization problem, path planning for mobile robot refers to searching an optimal or near-optimal path under different types of constrains in complex environments. In this paper, a self-adaptive learning particle swarm optimization(SLPSO) with different learning strategies is proposed to address this problem. First, we transform the path planning problem into a minimisation multi-objective optimization problem and formulate the objective function by considering three objectives: path length, collision risk degree and smoothness. Then, a novel self-adaptive learning mechanism is developed to adaptively select the most suitable search strategies at different stages of the optimization process, which can improve the search ability of particle swarm optimization(PSO). Moreover, in order to enhance the feasibility of the generated paths, we further apply the new bound violation handling schemes to restrict the velocity and position of each particle. Finally, experiments respectively with a simulated robot and a real robot are conducted and the results demonstrate the feasibility and effectiveness of SLPSO in solving mobile robot path planning problem. | Guangsheng LI Wusheng CHOU | 2018 | Science China(Information Sciences)2018，61，5： | 46 |

| 3 | Outline of Uranium Resources Characteristics and Metallogenetic Regularity in China显示文摘Uranium,as one of twenty-six kinds of important minerals in China,is strategic resource and energy mineral,which has been thoroughly investigated in the project of National Potential Evaluation of Uranium Resource.During the implementation of this project,the authors summarized the metallogenic regularity of uranium resource in China systematically,through the researches of geological characteristics of uranium resource,uranium deposits type(genetic and prediction type),temporal and spatial distribution,and metallogenic series.Based on the investigation of present situation and progress in uranium exploration,this paper proposes the uranium deposits in China should be divided into 4 classes,9 types,21 subtypes in genetic,and 50 types in prediction;suggests to divide China into 29 uranium metallogenic belts and 20 uranium prospective area,and constructs 20uranium-polymetallic metallogenic series,through summarizing temporal and spatial distribution characteristics and metallogenic regularity of uranium deposits in China.The above research is beneficial to the comprehensive understanding of regional uranium metallogenic regularity,and will direct the uranium exploration in the future. | CAI Yuqi ZHANG Jindai LI Ziying GUO Qingyin SONG Jiye FAN Honghai LIU Wusheng QI Fucheng ZHANG Minglin | 2015 | Acta Geologica Sinica(English Edition)2015，89，3： | 11 |
| 4 | Seasonal variations of stable isotope in precipitation and moisture transport at Yushu,eastern Tibetan Plateau显示文摘Precipitation δ 18O at Yushu, eastern Tibetan Plateau, shows strong fluctuation and lack of clear seasonality. The seasonal pattern of precipitation stable isotope at Yushu is apparently different from either that of the southwest monsoon region to the south or that of the inland region to the north. This different seasonal pattern probably reflects the shift of different moisture sources. In this paper, we present the spatial comparison of the seasonal patterns of precipitation δ 18O, and calculate the moisture transport flux by using the NCAR/NCEP reanalysis data. This allows us to discuss the relation between moisture transport flux and precipitation δ 18O. This study shows that both the southwest monsoon from south and inland air mass transport from north affected the seasonal precipitation δ 18O at Yushu, eastern Tibetan Plateau. Southwest monsoon brings the main part of the moisture, but southwest transport flux is weaker than in the southern part of the Tibetan Plateau. However, contribution of the inland moisture from north or local evaporation moisture is enhanced. The combined effect is the strong fluctuation of summer precipitation δ 18O at Yushu and comparatively poor seasonality. | TIAN LiDe MA LingLong YU WuSheng LIU ZhongFang YIN ChangLiang ZHAO ZhongPing TANG Wei WANG Yu | 2008 | Science China Earth Sciences2008，51，8： | 9 |
| 5 | Climatic significance of δ^(18)O records from precipitation on the western Tibetan Plateau显示文摘Analysis of daily precipitation samples for stable oxygen isotopes (δ18O) collected at the Shiquanhe and Gêrzê (Gaize, Gertse) stations in the Ngari (Ali) region on the western Tibetan Plateau indicates that air temperature affects the δ18O variations in precipitation at these stations. In summer, Shiquanhe and Gêrzê show strongly similar trends in precipitation δ18O, especially in simultaneous precipitation events. Moreover, both stations experienced low δ18O values in precipitation during the active monsoon period, resulting from the southwest monsoon (the summer phase of the Indian monsoon). However, during the break monsoon period (during the summer rainy season, when the monsoon circulation is disrupted), δ18O values in summer precipitation remain relatively high and local moisture recycling generally controls the moisture sources. Air temperature correlations with δ18O strengthen during the non-monsoon period (January―June, and October―December) due to continental air masses and the westerlies. In addition, evaporation also influences the δ18O variations in precipitation. The observed temporal and spatial variations of δ18O in precipitation on the western Tibetan Plateau and adjacent regions show that the late May and early June-the late August and early September time frame provides an important period for the transportation of moisture from various sources on the Tibetan Plateau, and that the region of the West Kunlun-Tanggula Ranges acts as a significant climatic divide on the Plateau, perhaps for all of western China. | YU WuSheng MA YaoMing SUN WeiZhen WANG Yu | 2009 | Chinese Science Bulletin2009，54，16： | 9 |
| 6 | Sintering Properties and Optimal Blending Schemes of Iron Ores显示文摘In order to obtain good sintering performance,it is important to understand sintering properties of iron ores.Sintering properties including chemical composition,granulation and high-temperature behaviors of ores from China,Brazil and Australia.Furthermore,several indices were defined to evaluate sintering properties of iron ores.The results show that:for chemical composition,Brazilian ores present high TFe,low SiO2,and low Al2O3 content.For granulation,particle diameter ratio of Brazilian ores are high;particle intermediate fraction of Chinese concentrates are low;and average particle size and clay type index of Australian ores are high.For high-temperature properties,ores from China,Brazil and Australia present different characteristics.Ores from different origins should be mixed together to obtain good high-temperature properties.According to the analysis of each ore's sintering properties,an ore blending scheme(Chinese concentrates 20%+Brazilian ores 40%+Australian ores 40%) was suggested.Moreover,sinter pot test using blending mix was performed,and the results indicated that the ore blending scheme led to good sintering performance and sinter quality. | Dauter0liveira WUSheng—li DAIYu—ming XUJian CHEN Hong | 2012 | Journal of Iron and Steel Research(International)2012，19，6： | 9 |
| 7 | Mechanical properties and associated seismic isolation effects of foamed concrete layer in rock tunnel显示文摘Foamed concrete has a good energy absorption capability and can be used as seismic isolation material for tunnels. This study aims to investigate the mechanical properties and associated seismic isolation effects of foamed concrete layer in rock tunnel. For this, a series of uniaxial/triaxial compression tests was conducted to understand the effects of concrete density, confining stress and strain rate on the mechanical properties of foamed concrete. The direct shear tests were also performed to investigate the effects of concrete density and normal stress on the nonlinear behaviors of foamed concrete layer-lining interface. The test results showed that the mechanical properties of foamed concrete are significantly influenced by the concrete density. The foamed concrete also has high volumetric compressibility and strain-rate dependence. The peak stress. residual stress. shear stiffness and residual friction coefficient of the foamed concrete layer-lining interface are influenced by the foamed concrete density and normal stress applied. Then, a crushable foam constitutive model was constructed using ABAQUS software and a composite exponential model was also established to study the relationship between shear stress and shear displacement of the interface, in which their parameters were fitted based on the experimental results. Finally, a parametric analysis using the finite element method(FEM) was conducted to understand the influence of foamed concrete layer properties on the seismic isolation effect, including the density and thickness of the layer as well as the shear stiffness and residual friction coefficient of the interface. It was revealed that lower density and greater thickness in addition to smaller shear stiffness or residual friction coefficient of the foamed concrete layer could yield better seismic isolation effect, and the influences of the first two tend to be more significant. | Shaosen Ma Weizhong Chen Wusheng Zhao | 2019 | Journal of Rock Mechanics and Geotechnical Engineering2019，11，1： | 8 |
| 8 | Isotopic composition of atmospheric water vapor before and after the monsoon's end in the Nagqu River Basin显示文摘Atmospheric water vapor samples were col-lected in the Nagqu River Basin in the middle of Tibetan Plateau between August and October in 2004. Results show that there exist some fluctuations of the δ 18O of atmospheric water vapor, especially before and after the monsoon’s end. Moreover, the variety trend of the δ 18O of atmospheric water vapor inverse correlates with that of dew point. Precipitation events make an important effect upon the variation of δ 18O of atmospheric water vapor. During the whole sampling pe-riod, the δ 18O values of atmospheric water vapor are low while precipitation events occurred. The moisture origins also contribute to the variation of δ 18O of atmospheric water vapor. The oceanic moisture transported by the southwest monsoon results in lower δ18O of atmospheric water vapor in the Nagqu River Basin. Compared with the influence of the oceanic moisture, the δ 18O values, however, appear high re-sulting from the effect of the continental air mass in this re-gion. | YU Wusheng YAO Tandong TIAN Lide WANG Yu YIN Changliang | 2005 | Chinese Science Bulletin2005，50，23： | 7 |

| 10 | Co-pyrolysis of bituminous coal and biomass in a pressured fluidized bed显示文摘An experimental study on co-pyrolysis of bituminous coal and biomass was performed in a pressured fluidized bed reactor.The blend ratio of biomass in the mixture was varied between 0 and 100 wt%,and the temperature was over a range of 550–650℃ under 1.0 MPa pressure with different atmospheres.On the basis of the individual pyrolysis behavior of bituminous coal and biomass,the influences of the biomass blending ratio,temperature,pressure and atmosphere on the product distribution were investigated.The results indicated that there existed a synergetic effect in the co-pyrolysis of bituminous coal and biomass in this pressured fluidized bed reactor,especially when the condition of bituminous coal and biomass blend ratio of 70:30(w/w),600℃,and 0.3 MPa was applied.The addition of biomass influenced the tar and char yields and gas and tar composition during co-pyrolysis.The tar yields were higher than the calculated values from individual pyrolysis of each fuel,and consequently the char yields were lower.The experimental results showed that the composition of the gaseous products was not in accordance with those of their individual fuel.The improvement of composition in tar also indicated synergistic effect in the co-pyrolysis. | Yong Huang Ningbo Wang Qiaoxia Liu Wusheng Wang Xiaoxun Ma | 2019 | Chinese Journal of Chemical Engineering2019，27，7： | 7 |
| 11 | Topographic species-habitat associations of tree species in a heterogeneous tropical karst seasonal rain forest, China显示文摘Aims Tropical and subtropical karst forests of south China are under increas-ing pressure from over-exploitation causing widespread habitat degra-dation and biodiversity loss.Previous research has demonstrated that topography,as a proxy for resource availability,plays an important role in shaping tree species distributions in tropical forests.However,the association between growth stages and habitats types has not been considered in this analysis.Our aim was to examine the differences among different habitat types to determine whether tree species show similar species-habitat associations at young and mature life stages.Methods We used multivariate regression tree analysis to examined species-habitat associations among eight topographically defined habitats.The results were tested with a torus-translation test and canonical correspondence analysis(CCA)for 74 species in a 15 ha karst tropi-cal seasonal rain forest at the Nonggang National Natural Reserve in south China.We considered two life stages(young and mature)of trees species that showed a positive association with topography.Important Findings We found marked differences in community characteristics and number of associations among the eight habitats.Of the 74 species subjected to torus-translation test,63 had significant positive and 70 had significant negative associations with one or more of the eight habitats.Positive associations were more frequent in higher elevation habitats and negative associations were more frequent in lower eleva-tion habitats.This suggests that edaphic and hydrological variation related to topography play important roles in habitat partitioning in heterogeneous karst forests.For the 63 tree species with significant positive associations to at least one habitat,40 of them had the same positive association at young and mature life stages.The CCA revealed that the six topographic variables considered had consistent relation-ships with species distribution among all individuals and their two life stages.This indicates that most of the karst forest tree species show consistent associations with a single habitat throughout their life.We conclude that niche differentiation plays an important role in main-taining the diversity of this heterogeneous species-rich karst forest. | Yili Guo Bin Wang Azim U.Mallik Fuzhao Huang Wusheng Xiang Tao Ding Shujun Wen Shuhua Lu Dongxing Li Yunlin He Xiankun Li | 2017 | Journal of Plant Ecology2017，10，3： | 6 |
| 12 | SCStore: Managing Scientific Computing Packages for Hybrid System with Containers显示文摘Managing software packages in a scientific computing environment is a challenging task, especially in the case of heterogeneous systems. It is error prone when installing and updating software packages in a sophisticated computing environment. Testing and performance evaluation in an on-the-fly manner is also a troublesome task for a production system. In this paper, we discuss a package management scheme based on containers. The newly developed method can ease the maintenance complexity and reduce human mistakes. We can benefit from the self-containing and isolation features of container technologies for maintaining the software packages among intricately connected clusters. By deploying the Super Computing application Strore(SCStore) over the WAN connected world-largest clusters, it proved that it can greatly reduce the effort for maintaining the consistency of software environment and bring benefit to achieve automation. | Wusheng Zhang Jiao Lin Weiping Xu Haohuan Fu Guangwen Yang | 2017 | Tsinghua Science and Technology2017，22，6： | 5 |
| 13 | What Determines China's Grain Imports and Self-sufficiency? The Role of Rising Domestic Costs and Varying World Market Prices显示文摘China s grain sectors have faced unprecedented challenges in recent years as the ever-increasing and historically high level of grain output has failed to reduce grain imports. On the contrary, high grain imports and high domestic stock have accompanied historically high domestic output, a situation dubbed the 'triple high' phenomenon in current policy discussion. This paper explores the role of widening domestic-world market price gaps in determining the triple high phenomenon.Unlike earlier studies that relied on production capacities, this paper argues that domestic production and demand (hence imports) are functions of domestic and world market prices and proposes an analytical framework to explicitly capture such price gaps under restricted trade linkages in general equilibrium. Following this approach, a set of price scenarios for the 2011-2020 period are constructed and simulated in a computable general equilibrium model. Results from the core scenarios, in which recent domestic and world market price trends are assumed to continue, suggest that further widening price gaps would substantially increase grain imports and reduce domestic output (by 60 million tons) and self-sufficiency ratios from base levels. In the alternative scenarios with larger (smaller) price gaps, we find higher (lower) imports and larger (smaller) decreases in domestic output and self-sufficiency ratios. Such results provide important policy implications as China's agricultural policy undergoes significant adjustment. | Wusheng Yu Tianxiang Li Jing Zhu | 2019 | China & World Economy2019，27，5： | 5 |
| 14 | Molecular architecture of the luminal ring of the Xenopus laevis nuclear pore complex显示文摘The nuclear pore complex(NPC)mediates the flow of substances between the nucleus and cytoplasm in eukaryotic cells.Here we report the cryo-electron tomography(cryo-ET)structure of the luminal ring(LR)of the NPC from Xenopus laevis oocyte.The observed key structural features of the LR are independently confirmed by single-particle cryo-electron microscopy(cryo-EM)analysis.The LR comprises eight butterfly-shaped subunits,each containing two symmetric wings.Each wing consists of four elongated,tubular protomers.Within the LR subunit,the eight protomers form a Finger domain,which directly contacts the fusion between the inner and outer nuclear membranes and a Grid domain,which serves as a rigid base for the Finger domain.Two neighboring LR subunits interact with each other through the lateral edges of their wings to constitute a Bumper domain,which displays two major conformations and appears to cushion neighboring NPCs.Our study reveals previously unknown features of the LR and potentially explains the elastic property of the NPC. | Yanqing Zhang Sai Li Chao Zeng Gaoxingyu Huang Xuechen Zhu Qifan Wang Kunpeng Wang Qiang Zhou Chuangye Yan Wusheng Zhang Guangwen Yang Minhao Liu Qinghua Tao Jianlin Lei Yigong Shi | 2020 | Cell Research2020，30，6： | 4 |

| 16 | Genome-wide Investigation of micro RNAs and Their Targets in Brassica rapa ssp. pekinensis Root with Plasmodiophora brassicae Infection显示文摘Increasing evidence has revealed that micro RNAs play a pivotal role in the post transcriptional regulation of gene expression in response to pathogens in plants. However, there is little information available about the expression patterns of mi RNAs and their targets in Chinese cabbage(Brassica rapa ssp. pekinensis) under Plasmodiophora brassicae stress. In the present study, using deep sequencing and degradome analysis, a genome-wide identification of mi RNAs and their targets during P. brassicae stress was performed. A total of 221 known and 93 potentially novel mi RNAs were successfully identified from two root libraries of one control(635-10CK) and P. brassicae-treated Chinese cabbage samples(635-10T). Of these, 14 known and 10 potentially novel mi RNAs were found to be differentially expressed after P. brassicae treatment. Degradome analysis revealed that the 223 target genes of the 75 mi RNAs could be potentially cleaved. KEGG(Kyoto Encyclopedia of Genes and Genomes)pathway analysis suggested that the putative target genes of the mi RNAs were predominately involved in selenocompound metabolism and plant hormone signal transduction. Then the expression of 12 mi RNAs was validated by quantitative real-time PCR(q RT-PCR). These results provide insights into the mi RNA-mediated regulatory networks underlying the stress response to the plant pathogen P. brassicae. | WEI Xiaochun XU Wen YUAN Yuxiang YAO Qiuju ZHAO Yanyan WANG Zhiyong JIANG Wusheng ZHANG Xiaowei | 2016 | Horticultural Plant Journal2016，2，4： | 3 |
| 17 | Structure evolution of Y_2O_3 nanoparticle/Fe composite during mechanical milling and annealing显示文摘Fe-25 wt% Y2O3composite powders have been fabricated by mechanical milling(MM) Fe powders of 100 μm in diameter and Y2O3nanoparticles in an argon atmosphere for the milling periods of4,8,12,24,36,and 48 h,respectively.The features of these powders were characterized by using X-ray diffraction(XRD),scanning electron microscopy(SEM),electron probe micro analyzer(EPMA) and transmission electron microscopy(TEM).The experimental results showed that the mean particle size and crystalline size of MM powders decreased with the milling time increasing.All the elements distributed homogenously inside the powders after 48 h of MM.The lattice constant of the matrix α-Fe kept constant with the milling time,and no solid solution took place during MM process.After 8 h of MM,the α-Fe in each powder became nanocrystalline.After 48 h of MM,Y2O3changes from nanostructure into amorphous structure,and the crystalline size of α-Fe further decreased to 10 nm.The Y2O3in the powders mechanically milled for 48 h kept the amorphous structure after being annealed at 400 1C,and starts to crystallize when the powders are annealed at 600 1C.The amorphous Y2O3contains a small amount of Fe,and crystalline FeYO3appears at 800 1C. | Tong Liu Hailong Shen Chenxi Wang Wusheng Chou | 2013 | Progress in Natural Science:Materials International2013，23，4： | 2 |
| 18 | An optimized protocol for stepwise optimization of real-time RT-PCR analysis显示文摘Computational tool-assisted primer design for real-time reverse transcription(RT)PCR(qPCR)analysis largely ignores the sequence similarities between sequences of homologous genes in a plant genome.It can lead to false confidence in the quality of the designed primers,which sometimes results in skipping the optimization steps for qPCR.However,the optimization of qPCR parameters plays an essential role in the efficiency,specificity,and sensitivity of each gene’s primers.Here,we proposed an optimized approach to sequentially optimizing primer sequences,annealing temperatures,primer concentrations,and cDNA concentration range for each reference(and target)gene.Our approach started with a sequence-specific primer design that should be based on the single-nucleotide polymorphisms(SNPs)present in all the homologous sequences for each of the reference(and target)genes under study.By combining the efficiency calibrated and standard curve methods with the 2−ΔΔCt method,the standard cDNA concentration curve with a logarithmic scale was obtained for each primer pair for each gene.As a result,an R 2≥0.9999 and the efficiency(E)=100±5% should be achieved for the best primer pair of each gene,which serve as the prerequisite for using the 2^(−ΔΔCt) method for data analysis.We applied our newly developed approach to identify the best reference genes in different tissues and at various inflorescence developmental stages of Tripidium ravennae,an ornamental and biomass grass,and validated their utility under varying abiotic stress conditions.We also applied this approach to test the expression stability of six reference genes in soybean under biotic stress treatment with Xanthomonas axonopodis pv.glycines(Xag).Thus,these case studies demonstrated the effectiveness of our optimized protocol for qPCR analysis. | Fangzhou Zhao Nathan A.Maren Pawel Z.Kosentka Ying-Yu Liao Hongyan Lu James R.Duduit Debao Huang Hamid Ashrafi Tuanjie Zhao Alejandra I.Huerta Thomas G.Ranney Wusheng Liu | 2021 | Horticulture Research2021，8，1： | 2 |
