Topos co-evanescents generalisations Algebraic Geometry
2011/9/5
Abstract: This article is devoted to studying a topos introduced by Faltings for the purpose of $p$-adic Hodge theory. We present a new approach based on a generalisation of Deligne's co-vanishing top...

Abstract: We study, in a global uniform manner, the quotient of the ring of polynomials in l sets of n variables, by the ideal generated by diagonal quasi-invariant polynomials for general permutation...
Abstract: In this paper, we develop a diamond graph theory and apply the theory to the (co)homology of the Lie algebra generated by positive systems of the classical semi-simple Lie algebras over the ...
Co-evolution of Selection and Influence in Social Networks
Selection and Influence Social Networks
2011/9/14
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network(link structure) can change with time. We propose a
model of co-evolving networks where both nod...
Resolving Author Name Homonymy to Improve Resolution of Structures in Co-author Networks
Improve Resolution Co-author Networks
2011/9/13
We investigate how author name homonymy distorts clustered large-scale co-author networks, and present a simple, e ective, scal-able and generalizable algorithm to ameliorate such distortions. We eval...

干旱半干旱区的CO 2浓度升高对生态系统的影响及碳氮耦合研究进展
干旱半干旱区 CO2浓度 生态系统 碳氮耦合
2012/7/25
大气CO2浓度升高已成为全球备受关注的环境问题。CO2排放量的增加加剧了地球表层的温室效应，也对生态系统的结构和功能产生了重要影响。生态系统对CO2浓度升高的响应是一个长期的过程。在干旱半干旱区，CO2浓度的升高对生态系统生产力、植物、土壤和微生物等都有影响，尤其改变了生态系统中的碳循环，并加剧了生态系统对氮的需求。碳循环是生态系统重要的能量流通渠道；氮是生态系统最重要的营养元素之一，也是生态系统...
