1自闭症患者的光学脑成像研究显示文摘阐述了新近发展起来的无损光学脑功能成像技术.通过比较几种常用的脑成像技术,论述了光学脑成像研究自闭儿童皮层活动的可行性和便利性.总结了国内外目前利用光学脑成像研究自闭症的初步进展.作者的最新实验结果表明,具有较高自闭特质的儿童在共同注意任务中其前额叶的血液动力学响应与正常儿童不同.进一步利用光学脑成像研究脑皮层活动规律及其固有的特征,有望为儿童自闭症的早期诊断提供可靠的客观依据.李军 朱志方 朱绘霖 郭欢 张潇 SVANBERG Sune 2013华南师范大学学报(自然科学版)2013,45,6:4
2利用基于光学暗场反射测量的光学遥感技术探测飞行的农业害虫(英文)显示文摘【目的】本研究的目的是开发一种光学遥感技术实现在农田昼夜连续自动地监测农业害虫。【方法】一个望远镜通过对准远处的暗箱,得到一个低亮度水平的基线。当昆虫在望远镜的视野中飞过时,它散射的太阳光的光学信息就被连接到望远镜的记录系统采集到。在夜晚我们使用很强的灯光替代太阳光来照亮昆虫。【结果】昆虫计数、昆虫的振翅频率分析及反射光谱记录都获得成功。这表明使用暗场背向散射探测系统监测昆虫是可行的。手动释放的已知昆虫种类都具有独特的光谱特性。几种害虫特别是桃蛀螟Conogethes punctiferalis(Guenée)和短角异斑腿蝗Xenocatantops brachycerus(Willemse)都用本文描述的方法进行了成功识别。【结论】用暗场背向散射探测系统昼夜连续监测田间农业害虫是可行的。跟预期的一样,散射的振翅频率和光谱信息可以用来识别害虫。朱世明 李逸云 高丽娜 李天祺 赵光宇 Sune SVANBERG 路朝晖 胡建东 黄建荣 封洪强 2016昆虫学报2016,59,12:4
3A Data-Driven Clustering Recommendation Method for Single-Cell RNA-Sequencing Data显示文摘Recently,the emergence of single-cell RNA-sequencing(scRNA-seq)technology makes it possible to solve biological problems at the single-cell resolution.One of the critical steps in cellular heterogeneity analysis is the cell type identification.Diverse scRNA-seq clustering methods have been proposed to partition cells into clusters.Among all the methods,hierarchical clustering and spectral clustering are the most popular approaches in the downstream clustering analysis with different preprocessing strategies such as similarity learning,dropout imputation,and dimensionality reduction.In this study,we carry out a comprehensive analysis by combining different strategies with these two categories of clustering methods on scRNA-seq datasets under different biological conditions.The analysis results show that the methods with spectral clustering tend to perform better on datasets with continuous shapes in two-dimension,while those with hierarchical clustering achieve better results on datasets with obvious boundaries between clusters in two-dimension.Motivated by this finding,a new strategy,called QRS,is developed to quantitatively evaluate the latent representative shape of a dataset to distinguish whether it has clear boundaries or not.Finally,a data-driven clustering recommendation method,called DDCR,is proposed to recommend hierarchical clustering or spectral clustering for scRNA-seq data.We perform DDCR on two typical single cell clustering methods,SC3 and RAFSIL,and the results show that DDCR recommends a more suitable downstream clustering method for different scRNA-seq datasets and obtains more robust and accurate results.Yu Tian Ruiqing Zheng Zhenlan Liang Suning Li Fang-Xiang Wu Min Li 2021Tsinghua Science and Technology2021,26,5:3
4Recent Progress and Perspectives of Sodium Metal Anodes for Rechargeable Batteries显示文摘Sodium metal anodes have attracted significant attention due to their high specific capacity,low redox potential and abundant resources.However,the dendrites and unstable solid electrolyte interphase(SEI)of sodium anodes restrict the development of sodium metal batteries.This review includes the recent progress on the Na anode protection in sodium metal batteries.The strategies are summarized as modified three-dimensional current collectors,artificial solid electrolyte interphases,and electrolyte modifications.Conclusions and perspectives are envisaged for the further understanding and development of Na metal anodes.FANG Hengyi GAO Suning ZHU Zhuo REN Meng WU Quan LI Haixia LI Fujun 2021Chemical Research in Chinese Universities2021,37,2:3

8Effects of harvesting method and date on yield loss and seed quality of rapeseed显示文摘China is one of the major rapeseed production countries in the world,but harvesting mechanization was still backward,and high harvest loss was a key inhibiting factor for rapeseed production.To obtain optimum harvesting date for winter rape in the Yangtze River Valley of China,artificial simulated combine harvesting and artificial two-stage harvesting were adopted to find correlations between harvesting date,rape variety,seed oil content,protein content,grain moisture rate,rapeseed straw moisture content,rapeseed unthreshing rate,grain drop loss rate,thousand seeds weight(TSW),and harvesting economic coefficient(HEC).Analysis of variance showed that rapeseed oil content,protein content and TSW were correlated with rape variety;HEC was correlated with harvesting method and rape variety.Rape variety was the dominant factor of rapeseed oil content,protein content,TSW and HEC.Grain moisture rate,un-threshing rate,grain drop loss rate and straw moisture content were correlated with harvesting method and date.Harvesting date was the dominant factor of rapeseed moisture rate,un-threshing rate,grain drop loss rate and straw moisture rate.Single factor tests further proved that harvesting date had less impact on rapeseed oil content,protein content,TSW and HEC.It showed little correlation with rapeseed quality except grain moisture rate.The optimum harvesting date could be known by change in straw moisture content.The combined harvesting should be carried out during the grain moisture content of 15%-20%with TSW stabilized in the highest level.The twostage harvesting cutting should be carried out at the grain moisture content of 35%-40%.This research offered a reference to harvesting method and date for rape cultivated in the Yangtze River Valley.Min Zhang Chongyou Wu Mei Jin Senlin Mu Suning Liang Qing Tang 2019Oil Crop Science2019,4,3:3
9EXISTENCE,MULTIPLICITY AND STABILITY RESULTS FOR POSITIVE SOLUTIONS OF NONLINEAR p-LAPLACIAN EQUATIONS显示文摘This paper studies the existence of positive solutions of the Dirichlet problem for the nonlinear equation involving p-Laplacian operator: -△pu = λf(u) on a bounded smooth domain Ω in Rn. The authors extend part of the Crandall-Rabinowitz bifurcation theory to this problem. Typical examples are checked in detail and multiplicity of the solutions are illustrated. Then the stability for the associated parabolic equation is considered and a Fujita-type result is presented.MALI SUNING 2004Chinese Annals of Mathematics,Series B2004,25,2:2

11Probing thermally-induced structural evolution during the synthesis of layered Li-, Na-, or K-containing 3d transition-metal oxides显示文摘Layered alkali-containing 3d transition-metal oxides are of the utmost importance in the use of electrode materials for advanced energy storage applications such as Li-,Na-,or K-ion batteries.A significant challenge in the field of materials chemistry is understanding the dynamics of the chemical reactions between alkali-free precursors and alkali species during the synthesis of these compounds.In this study,in situ high-resolution synchrotron-based X-ray diffraction was applied to reveal the Li/Na/K-ion insertion-induced structural transformation mechanism during high-temperature solid-state reaction.The in situ diffraction results demonstrate that the chemical reaction pathway strongly depends on the alkali-free precursor type,which is a structural matrix enabling phase transi-tions.Quantitative phase analysis identifies for the first time the decomposition of lithium sources as the most critical factor for the formation of metastable intermediates or impurities during the entire process of Li-rich layered Li[Li_(0.2)Ni_(0.2)Mn_(0.6)]O_(2) formation.Since the alkali ions have different ionic radii,Na/K ions tend to be located on prismatic sites in the defective layered structure(Na_(2/3-x)[Ni_(0.25)Mn_(0.75)]O_(2) or K_(2/3-x)[Ni_(0.25)Mn_(0.75)]O_(2))during calcination,whereas the Li ions prefer to be localized on the tetrahedral and/or octahedral sites,forming O-type structures.Weibo Hua Xiaoxia Yang Nicola PMCasati Laijun Liu Suning Wang Volodymyr Baran Michael Knapp Helmut Ehrenberg Sylvio Indris 2022eScience2022,2,2:2
