1亚洲人造地表覆盖遥感精细化分类与分布特征分析显示文摘人造地表覆盖是刻画人类活动对陆地表层生态系统影响的重要因素,具有高度动态、结构复杂和类型镶嵌等特征.由于当前缺乏有效的洲际尺度人造地表覆盖精细化遥感探测方法和高精度的数据产品,由此影响了城市化对区域气候、生态系统过程和全球环境变化影响评估的可靠性.本研究构建了人造地表覆盖等级层次结构分类系统,发展了基于2010年全球地表覆盖30m分辨率产品(GlobeLand30)的人造地表覆盖二级类型像元组分提取的技术方法,研发了亚洲2010年高精度城市建成区及其内部城市不透水地表和植被覆盖组分比例数据产品.基于多源数据融合和专家知识方法获取的城市建成区及其内部组分分类的总体精度为90.79%;城市内部不透水地表比例组分信息提取平均相对误差为0.87,总体上数据产品具有较高的质量和可靠性.遥感精细化信息提取局部误差与不同气候带城市建筑与植被镶嵌程度密切有关.遥感精细化分类表明,亚洲城市建成区面积181785.96km^2,占亚洲陆表面积的0.59%;城市内部结构组分中,城市不透水地表总面积为116504.72km^2,占亚洲城市建成区面积的64.09%,植被和裸土面积占34.56%.在空间上,城市不透水地表自东向西呈现集聚式、分散式和无显著分布特征三级梯度.中国、印度和日本等国家,城市不透水地表总面积排在前三位,分别占亚洲城市不透水地表面积的32.77%、16.10%和11.93%.研究发现,城市建成区内部不透水地表与植被覆盖组分比例与国家的经济发展程度及区域气候环境密切相关,对于经济较为发达的国家,城市建成区内部镶嵌类型中不透水地表比例相对较低,如韩国、新加坡城市不透水地表比例约为50~60%,公共绿地植被面积比例相对较高,而对于经济发展水平较低的国家,城市建成区内部镶嵌类型中城市不透水地表比例则接近或超过80%.城市建成区内不透水地表、植被组分及空间分布特征集中反映了亚洲地区人口集聚和经济发展水平以及对子流域环境健康状况影响程度.匡文慧 陈利军 刘纪远 XIANG WeiNing 迟文峰 LU DengSheng 杨天荣 潘涛 刘爱琳 2016中国科学:地球科学2016,46,9:13
2Remote sensing-based artificial surface cover classification in Asia and spatial pattern analysis显示文摘Artificial surfaces, characterized with intensive land-use changes and complex landscape structures, are important indicators of human impacts on terrestrial ecosystems. Without high-resolution land-cover data at continental scale, it is hard to evaluate the impacts of urbanization on regional climate, ecosystem processes and global environment. This study constructed a hierarchical classification system for artificial surfaces, promoted a remote sensing method to retrieve subpixel components of artificial surfaces from 30-m resolution satellite imageries(Globe Land30) and developed a series of data products of high-precision urban built-up areas including impervious surface and vegetation cover in Asia in 2010. Our assessment, based on multisource data and expert knowledge, showed that the overall accuracy of classification was 90.79%. The mean relative error for the impervious surface components of cities was 0.87. The local error of the extracted information was closely related to the heterogeneity of urban buildings and vegetation in different climate zones. According to our results, the urban built-up area was 18.18×104 km2, accounting for 0.59% of the total land surface areas in Asia; urban impervious surfaces were 11.65×104 km2, accounting for 64.09% of the total urban built-up area in Asia. Vegetation and bare soils accounted for 34.56% of the urban built-up areas. There were three gradients: a concentrated distribution, a scattered distribution and an indeterminate distribution from east to west in terms of spatial pattern of urban impervious surfaces. China, India and Japan ranked as the top three countries with the largest impervious surface areas, which respectively accounted for 32.77%, 16.10% and 11.93% of the urban impervious surface area of Asia. We found the proportions of impervious surface and vegetation cover within urban built-up areas were closely related to the economic development degree of the country and regional climate environment. Built-up areas in developed countries had relatively low impervious surface and high public green vegetation cover, with 50–60% urban impervious surfaces in Japan, South Korea and Singapore. In comparison, the proportion of urban impervious surfaces in developing countries is approaching or exceeding 80% in Asia. In general, the composition and spatial patterns of built-up areas reflected population aggregation and economic development level as well as their impacts on the health of the environment in the sub-watershed.KUANG WenHui CHEN LiJun LIU JiYuan XIANG WeiNing CHI WenFeng LU DengSheng YANG TianRong PAN Tao LIU AiLin 2016Science China Earth Sciences2016,59,9:12
3TRDMT1 exhibited protective effects against LPS-induced inflammation in rats through TLR4-NF-κB/MAPK-TNF-αpathway显示文摘Background:Inflammation is a complex physiological and pathological process.Although many types of inflammation are well characterized,their physiological func-tions are largely unknown.tRNA aspartic acid methyltransferase 1(TRDMT1)has been implicated as a stress-related protein,but its intrinsic biological role is unclear.Methods:We constructed a Trdmt1 knockout rat and adopted the LPS-induced sepsis model.Survival curve,histopathological examination,expression of inflammatory fac-tors,and protein level of TLR4 pathway were analyzed.Results:Trdmt1 deletion had no obvious impact on development and growth.Trdmt1 de-letion slightly increased the mortality during aging.Our data showed that Trdmt1 strongly responded in LPS-treated rats,and Trdmt1 knockout rats were vulnerable to LPS treat-ment with declined survival rate.We also observed more aggravated tissue damage and more cumulative functional cell degeneration in LPS-treated knockout rats compared with control rats.Further studies showed upregulated TNF-αlevel in liver,spleen,lung,and serum tissues,which may be explained by enhanced p65 and p38 phosphorylation.Conclusions:Our data demonstrated that Trdmt1 plays a protective role in inflamma-tion by regulating the TLR4-NF-κB/MAPK-TNF-αpathway.This work provides useful information to understand the TRDMT1 function in inflammation.Zhengguang Li Xiaolong Qi Xu Zhang Lei Yu Lijuan Gao Weining Kong Wei Chen Wei Dong Lijun Luo Dan Lu Lianfeng Zhang Yuanwu Ma 2022Animal Models and Experimental Medicine2022,5,2:5
4Risk identification and risk mitigation during metro station construction by enlarging shield tunnel combined with cut-and-cover method显示文摘Constructing a metro station by enlarging shield tunnels combined with a mining/cut-and-cover method provides a new method to solve the contradictions of construction time limits of shield tunnels and stations. As a new-style construction method, there are several specific risks involved in the construction process. Based on the test section of Sanyuanqiao station on Beijing metro line 10, and combined with the existing methods of risk identification at present, including a review of world-wide operational experience of similar projects, the study of generic guidance on hazards associated with the type of work being undertaken, and discussions with qualified and experienced staff from the project team, etc., the specific risks during the construction process of the metro station constructed by enlarging shield tunnels combined with the cut-and-cover method are identified. The results show that the specific risks mainly come from three construction processes which include constructing upper enclosure structures, excavating the soil between shield tunnels and demolishing shield segments. Then relevant risk mitigation measures are put forward. The results can provide references for scheme improvement and a comprehensive risk assessment of the new-style construction method.Zhang, Xinjin Liu, Weining Lu, Meili 2008Journal of Southeast University(English Edition)2008,24,S1:3

6Application of an antibody chip for screening differentially expressed proteins during peach ripening and identification of a metabolon in the SAM cycle to generate a peach ethylene biosynthesis model显示文摘Peach(Prunus persica)is a typical climacteric fruit that produces ethylene rapidly during ripening,and its fruit softens quickly.Stony hard peach cultivars,however,do not produce large amounts of ethylene,and the fruit remains firm until fully ripe,thus differing from melting flesh peach cultivars.To identify the key proteins involved in peach fruit ripening,an antibody-based proteomic analysis was conducted.A mega-monoclonal antibody(mAb)library was generated and arrayed on a chip(mAbArray)at a high density,covering~4950 different proteins of peach.Through the screening of peach fruit proteins with the mAbArray chip,differentially expressed proteins recognized by 1587 mAbs were identified,and 33 corresponding antigens were ultimately identified by immunoprecipitation and mass spectrometry.These proteins included not only important enzymes involved in ethylene biosynthesis,such as ACO1,SAHH,SAMS,and MetE,but also novel factors such as NUDT2.Furthermore,protein–protein interaction analysis identified a metabolon containing SAHH and MetE.By combining the antibody-based proteomic data with the transcriptomic and metabolic data,a mathematical model of ethylene biosynthesis in peach was constructed.Simulation results showed that MetE is an important regulator during peach ripening,partially through interaction with SAHH.Wenfang Zeng Liang Niu Zhaohui Wang Xiaobei Wang Yan Wang Lei Pan Zhenhua Lu Guochao Cui Weining Weng Mingqiao Wang Xun Meng Zhiqiang Wang 2020Horticulture Research2020,7,1:2
7Dithiol treatments enhancing the efficiency of hybrid solar cells based on PTB7 and CdSe nanorods显示文摘We report the fabrication of polymer/inorganic hybrid solar cells (HSCs) based on CdSe nanorods (NRs) and the semiconducting polymer PTB7. The power conversion efficiency of HSCs can be significantly enhanced by engineering the polymer/nanocrystal interface with ethanedithiol (EDT) and 1,4-benzenedithiol (1,4-BDT) treatments and reached 2.58% and 2.79%, respectively. These results were preferable to that of a pyridine-coated NR-based device (1.75%). This improvement was attributed to the thiol groups of EDT and 1,4-BDT, which can tightly coordinate the Cd ions to form Cd-thialate on CdSe NR surfaces, thereby effectively passivating the NR surface and reducing the active layer defects. Therefore, the rate of exciton generation and dissociation was enhanced and led to the improvement of the device performance.Weining Luo Tonggang Jiu Chaoyang Kuang Bairu Li Fushen Lu Junfeng Fang 2015Nano Research2015,8,9:2

14Cooperative planning ofmulti-agent systems based on task-oriented knowledge fusion with graph neural networks显示文摘Cooperative planning is one of the critical problems in the field of multi-agent system gaming.This work focuses on cooperative planning when each agent has only a local observation range and local communication.We propose a novel cooperative planning architecture that combines a graph neural network with a task-oriented knowledge fusion sampling method.Two main contributions of this paper are based on the comparisons with previous work:(1)we realize feasible and dynamic adjacent information fusion using GraphSAGE(i.e.,Graph SAmple and aggreGatE),which is the first time this method has been used to deal with the cooperative planning problem,and(2)a task-oriented sampling method is proposed to aggregate the available knowledge from a particular orientation,to obtain an effective and stable training process in our model.Experimental results demonstrate the good performance of our proposed method.Hanqi DAI Weining LU Xianglong LI Jun YANG Deshan MENG Yanze LIU Bin LIANG 2022Frontiers of Information Technology & Electronic Engineering2022,23,7:0
15MBE growth of high absorption mid-IR type-II InAs/GaSb superlattices显示文摘Two kinds of short-period type II superlattices(SLs)InAs(6 monolayers(MLs))/GaSb(3 MLs)and InAs(8 MLs)/GaSb(8 MLs)which can serve for mid-infrared(MIR)detection have been grown by molecular beam epitaxy(MBE)on p-type GaSb(100)substrates.The cutoff wavelength for the two superlattices(SLs)was found to be around 4.8 lm at 300 K.The high resolution X-ray diffraction(HRXRD)measurements indicated that the InAs(8 MLs)/GaSb(8 MLs)SLs have better crystalline quality than that of the InAs(6 MLs)/GaSb(3 MLs)SLs.However,compared with infrared absorption in the 2.5–4.3 lm range,the optical absorption of InAs(6 MLs)/GaSb(3MLs)SLs was more excellent.This can be attributed to increase probability of the electron and hole wave function overlap in the thinner period thickness.Geng Wang Lu Wang Hong Chen Wenxin Wang Zhenwu Shi Yulong Chen Miao He Pingyuan Lu Weining Qian 2014Chinese Science Bulletin2014,59,20:0
16Patterns and impacting factors of gene evolutionary rate between wild and cultivated emmer wheat(Triticum turgidum)显示文摘Tetraploid emmer wheat(Triticum turgidum L.,BBAA)is the founder progenitor of bread wheat,providing the valuable genetic resource and gene pool for wheat improvement.However,the evolutionary trajectory of tetraploid wheat,especially the evolutionary fate of different types of genes has not been well studied.In this study,the rate of non-synonymous substitution(dN)and synonymous substitution(dS)was calculated by comparing the orthologs between the wild emmer and cultivated durum wheat at the whole genome and subgenome levels to obtain the positively selected genes(PSGs)and negatively selected genes(NSGs).Then,mutation rate,gene length,exon number,GC content,codon bias,and expression level were comprehensively investigated and compared between the PSGs and NSGs.Within both wild emmer and cultivated durum wheat,PSGs between A and B subgenome displayed shorter gene and exon lengths as well as fewer exon numbers compared with NSGs,whereas from wild emmer to cultivated durum wheat,PSGs showed longer gene length and more exon numbers.Furthermore,PSGs displayed much higher expression levels and stronger codon usage bias,but lower genetic diversity compared with NSGs.Finally,two PSGs TdER1-6B,and TdLC7-2A,were found to play the crucial roles in regulating grain width and plant height of tetraploid wheat,respectively.This study systematically investigated the evolutionary,structural,and functional difference between PSGs and NSGs in tetraploid wheat,which will contribute to a better understanding of the selective mode and evolutionary trajectory during wheat domestication and evolution.Peng-Zheng Lei Qi Ai Zhu-Pei Xiong Jia-Nan Lu Xiu-Lan Wei Weining Song Xiao-Qin Liu Xiao-Jun Nie 2023Journal of Systematics and Evolution2023,61,2:0
17Expression of Syk in non-small cell lung cancer and its relationship with clinicopathological parameters显示文摘This study aims to research the expression of spleen tyrosine kinase(Syk)in non-small cell lung cancer(NSCLC)and the relationship between Syk and clinico-pathologic factors and p53.Immunohistochemistry was applied to detect the expression of Syk and p53 protein in 39 cases of NSCLC(23 cases of lung squamous cell can-cer,16 cases of lung adenocarcinoma)and tumor-sur-rounding normal lung tissues.The positive rate of Syk was 46.15%(18/39)and 100%(39/39)in NSCLC and tumor-surrounding normal lung tissues,respectively.The expres-sion level of Syk in NSCLC was significantly lower than that in tumor-surrounding normal lung tissues(P=0.000).The Syk expression was positively correlated with the p53 expression in NSCLC specimens(P=0.025).There was no significant association between Syk expression and lymph node metastasis,differentiation degree,tumor size and tumor node metastasis(TNM).The present study demonstrated that Syk was aberrantly expressed in the NSCLC and might have a significant impact on tumor growth and progression.Fen LAN Shengdao XIONG Weining XIONG Guopeng XU Xiaoxia LU 2009Frontiers of Medicine2009,3,1:0
