β¦ Synopsis
A comparison is made between two approaches to a Kramers-type reaction rate theory. The usual one is based on a linear coupling model between a particle and the medium oscillators. Use is made of two different separable reaction coordinates in the absence and presence of coupling, respectively. A more general model consists of Ε½ . assuming an arbitrary nonlinear coupling between the reactant and medium, making Ε½ . use of a single curvilinear reaction coordinate of the entire many-dimensional system Ε½ . reactant q medium . A comparison with the exact dynamic rate theory is made, showing its equivalence with the generalized stochastic theory.

## Abstract In this paper we develop a simulationβbased approach to stochastic dynamic programming. To solve the Bellman equation we construct Monte Carlo estimates of __Q__βvalues. Our method is scalable to high dimensions and works in both continuous and discrete state and decision spaces while a
The problem of two-site adsorption chromatography under linear conditions is considered by using the molecular dynamic theory of chromatography originally developed by Giddings and Eyring. The probabilistic description is made by using the characteristic function method, and the solution is obtained
