1Geo-rough Space显示文摘Rough set is a new approach to uncertainties in spatial analysis.In this paper,rough set symbols are simplified and standardized in terms of rough interpretation and specialized indication.Rough spatial entities and their topological relationships are also proposed in rough space,thus a universal intersected equation is developed,and rough membership function is further extended with the gray scale in our case study.We complete three works.First,a set of simplified rough symbols is advanced on the basis of existing rough symbols.Second,rough spatial entity is put forward to study the real world as it is,without forcing uncertainties into crisp set.Third,rough spatial topological relationships are studied by using rough matrix and their figures.The relationships are divided into three types,crisp entity and crisp entity (CC),rough entity and crisp entity (RC),and rough entity and rough entity (RR).A universal intersected equation is further proposed.Finally,the maximum and minimum maps of river thematic classification are generated via rough membership function and rough relationships in our case study.WANG Shuliang LI Deren SHI Wenzhong WANG Xinzhou 2003Geo-Spatial Information Science2003,6,1:12
2Nanoparticle-immersed paper imprinting mass spectrometry imaging reveals uptake and translocation mechanism of pesticides in plants显示文摘Design and discovery of carrier-mediated modified pesticides are vital for reducing pesticide dosage and increasing utilization,yet it remains a great challenge due to limited insights into plant translocation mechanisms.Nanostructure/nanoparticle assisted laser desorption/ionization strategy has established itself as a preferential analytical tool for biological tissue analysis,whereas potential applications in plant sciences are hindered with regard to the inability to slice plant leaves and petals.Herein,we report gold nanoparticle(AuNP)-immersed paper imprinting mass spectrometry imaging(MSI)for the spatiotemporal visualization of pesticide translocation in plant leaves.This approach plays a dual role in preserving spatial information and improving ionization efficiency for pesticides regardless of imaging artifacts due to homogenous AuNP deposition.Using this MSI platform,we proposed the elaborate plant translocation mechanism of agrochemicals for the first time,which is currently poorly understood.The dynamic processes of carrier-mediated pesticides can be clearly visualized,including crossing of plasma membranes by transporters,translocation downward in stems through the phloem,diffusion to the xylem and,conversely,accumulation at margins of the treated leaves.Moreover,this AuNP-assisted paper imprinting method could be highly compatible with laser-based MSI instruments,expediting researches across a broad range of fields,especially in nanomaterial development and life sciences.Xinzhou Wu Run Qin Hanxiang Wu Guangkai Yao Yue Zhang Ping Li Yizhu Xu Zhixiang Zhang Zhibin Yin Hanhong Xu 2020Nano Research2020,13,3:8

4Fluctuation with dust of de Sitter ground state of scalar-tensor gravity显示文摘An exact de Sitter solution of scalar-tensor gravity is found in our recent work,in which the non-minimal coupling scalar is rolling along a non-constant potential.Based on this solution,a dust-filled FRW universe is explored in frame of scalar-tensor gravity in this article.The efective dark energy induced by the sole non-minimal scalar can be quintessence-like,phantom-like,and more significantly,can cross the phantom divide.The rich and varied properties of scalar-tensor gravity even with only one scalar is shown.TANG YanKe ZHANG HongSheng CHEN ChiYi LI XinZhou 2014Science China(Physics,Mechanics & Astronomy)2014,57,3:1
5A local Martian crustal field model: Targeting the candidate landing site of the 2020 Chinese Mars Rover显示文摘Unlike Earth,Mars lacks a global dipolar magnetic field but is dominated by patches of a remnant crustal magnetic field.In 2021,the Chinese Mars Rover will land on the surface of Mars and measure the surface magnetic field along a moving path within the possible landing region of 20°W-50°W,20°N-30°N.One scientific target of the Rover is to monitor the variation in surface remnant magnetic fields and reveal the source of the ionospheric current.An accurate local crustal field model is thus considered necessary as a field reference.Here we establish a local crust field model for the candidate landing site based on the joint magnetic field data set from Mars Global Explorer(MGS)and Mars Atmosphere and Volatile Evolution(MAVEN)data combined.The model is composed of 1,296 dipoles,which are set on three layers but at different buried depths.The application of the dipole model to the joint data set allowed us to calculate the optimal parameters of their dipoles.The calculated results demonstrate that our model has less fitting error than two other state-of-the art global crustal field models,which would indicate a more reasonable assessment of the surface crustal field from our model.XinZhou Li ZhaoJin Rong JiaWei Gao Yong Wei Zhen Shi Tao Yu WeiXing Wan 2020Earth and Planetary Physics2020,4,4:1
6M@B_9 and M@B_(10) molecular wheels containing planar nona-and deca-coordinate heavy group 11, 12, and 13 metals (M=Ag, Au, Cd, Hg, In, Tl)显示文摘A density functional and ab initio theory investigation on M@B9 and M@B10 molecular wheels containing planar nona-and deca-coordinate heavy group 11, 12 and 13 metals (M=Ag, Au, Cd, Hg, In, Ti) has been performed. These unusual clusters all prove to be true minima on the potential energy surfaces of the systems and σ+π double aromatic in nature. The first two vertical one-electron detachment energies of M@B-10 (M=Ag, Au) anions and first two ionization potentials of M@B9 (M=Ag, Au) and M@B10 (M=Cd, Hg) neutrals were calculated to aid future experiments. The cluster complexes designed in this work may expend the domain of planar hyper-coordinate elements to include heavy group 11, 12, and 13 metals and serve as interesting candidates to be targeted in experiments.MIAO ChangQing, GUO JinChang & LI SiDian Institute of Materials Sciences and Department of Chemistry, Xinzhou Teachers’ University, Xinzhou 034000, China 2009Science China Chemistry2009,52,7:1

8Carbon-free D_(3d) [E_3ME_3]^(2-) (E=P,As;M=Ni,Pd,Pt):The smallest inorganic sandwich complexes with aromatic η~3-P_3^- and η~3-As_3^- ligands显示文摘A density functional theory and wave function theory investigation on the possibility of carbon-free phosphametallocenes [P3MP3]2-and arsenametallocenes [As3MAs3]2- (M=Ni, Pd, Pt) is presented in this work. Staggered singlet D3d [E3ME3]2- (E=P, As)-the smallest inorganic metallocenes possible to construct-proved to be the global minima of the heptaatomic sys- tems and may be targeted in future experiments. Cyclo-P3- and cyclo-As3- turned out to possess similar aromaticity to cyclo-P5- and cyclo-As5- and may serve as effective ligands to sandwich a wide range of transition metals. The first vertical electron detachment energies of Cs [E3ME3]Li+ monoanions with a staggered [E3ME3]2- sandwich core were predicted to be between 2.7 and 2.9 eV; the extent of stabilization by Li+ suggests that such materials be viable targets for experimental characterization.MIAO ChangQing, CHEN Qiang, GUO JinChang & LI SiDian Institute of Materials Science and Department of Chemistry, Xinzhou Teachers’ University, Xinzhou 034000, China 2010Science China Chemistry2010,53,4:0
9WORMHOLE AND THE DIMENSIONALITY OF SPACETIME IN EINSTEIN-GAUGE THEORIES显示文摘The wormhole effect is discussed in the d-dimensional Einstein-Yang-Mills theory.We show that the peak of the probability function leads to the explanation of the spontaneous compactification down to a four-dimensional spacetime and vanishing four-dimensional cosmological constant,i.e.,the observable spacetime must be four-dimensional and flat.LI Xinzhou ZHONG Yu 1990Chinese Physics Letters1990,7,6:0

11Application of Interval Newton Method to Solve Nonlinear Equations and Global Optimization显示文摘The basic principle of interval arithmetic and the basic algorithm of the interval Newton methods are introduced.The prototype algorithm can not find any zero in an interval that has zero sometimes,that is,it is instable.So the prototype relaxation procedure is improved in this paper.Additionally,an immediate test of the existence of a solution following branch_and_bound is proposed,which avoids unwanted computations in those intervals that have no solution.The numerical results demonstrat that the improved interval Newton method is superior to prototype algorithm in terms of solution quality,stability and convergent speed.LI Shuang XU Caijun WANG Xinzhou 2003Geo-Spatial Information Science2003,6,1:0
