In many applications,particularly in geophysics,we often have fluid trajectory data from floats,but little or no information about the underlying velocity field.The standard techniques for finding transport barriers,based for example on finite-time Lyapunov exponents,are then inapplicable.However,if there are invariant regions in the flow this will be reflected by a `bunching up of trajectories.We show that this can be detected by tools from topology.This is joint work with Michael Allshouse,Marko Budisic,and Tom Peacock.

含马兜铃酸(Aristolochic Acid,AA)中药引起的马兜铃酸肾病(Aristolochic Acid Nephropathy,AAN)这一现象已引起了人们的广泛关注,而目前我国尚缺乏一套从细胞和分子遗传突变水平来评价含马兜铃酸中药毒性作用的检测体系。因此,本课题希望通过研究摸索出一套检测含马兜铃酸中药毒性作用的体系。为了建立从提取到检测含马兜铃酸中药毒性作用的整套流程,本课题首先采用高
