无限多类别网络均衡问题中的收费计算

对于一个多类别的网络均衡问题,可以通过计算某个辅助问题的容量限制约束相应的乘子向量得到有效收费.本文通过计算拉格朗日函数的鞍点来计算乘子向量.借助于广义拉格朗日函数的稳定性和Uzawa算法非精确解的收敛性,得到鞍点序列的收敛性.其中离散化方法用于最小化广义拉格朗日函数的计算.     

A post-labeling strategy based on dye-induced peeling of the aptamer off single-walled carbon nanotubes for electrochemical aptasensing

A simple and efficient post-labeling strategy based on dye-induced peeling of the aptamer molecules off single-walled carbon nanotubes was developed for electrochemical aptasensing of thrombin with a detection limit down to 3 pM.

Solving semilinear differential equations by probabilistic methods

In this paper, by using Dirichlet form theory as a tool, we shall give an application of the reflecting diffusion processes to solving boundary value problems for semilinear differential equations.This project is supported by the National Natural Science Foundation of China.     

THE DIRICHLET PROBLEM FOR DIFFUSION EQUATION

Let D be a bounded domain in the d 1-dimensional Euclidean space R~(d 1). This paper aims at giving a probabilistis treatment of the Dirichlet problem for the following diffusion equation on D(1/2⊿ q)u(x,t)=/(t)u(x,t),(x,t)∈D,where q is a function to be specified later and ⊿ is the Laplace operator sum from i=1 to d(~2/(x_i~2)). The existence and uniqueness theorems are given, and furthermore, the probabilistie representation and martingale charaeterization of the solutions for diffusion equations are obtained.
