Sampling diffusive transition paths

Sampling diffusive transition paths.

The authors address the problem of sampling double-ended diffusive paths. The ensemble of paths is expressed using a symmetric version of the Onsager-Machlup formula, which only requires evaluation of the force field and which, upon direct time discretization, gives rise to a symmetric integrator that is accurate to second order. Efficiently sampling this ensemble requires avoiding the well-kno...

Title Sampling diffusive transition paths

Transition paths, diffusive processes, and preequilibria of protein folding.

Fundamental relationships between the thermodynamics and kinetics of protein folding were investigated using chain models of natural proteins with diverse folding rates by extensive comparisons between the distribution of conformations in thermodynamic equilibrium and the distribution of conformations sampled along folding trajectories. Consistent with theory and single-molecule experiment, dur...

Quality Control in Diffusive Sampling Networks

The urban centres are growing extremely quickly throughout Latin America and, as a consequence air pollution is also growing due to increasing traffic. The Clean Air Programme, financed by the Swiss Agency for Development and Cooperation (SDC), was carried out by the Swiss Foundation for Technical Cooperation (Swisscontact) was carried out in 6 Central American cities [1]. The project's goal wa...

Direct Sampling Method for Diffusive Optical Tomography

In this work, we are concerned with the di↵usive optical tomography (DOT) problem in the case when only one or two pairs of Cauchy data is available. We propose a simple and e cient direct sampling method (DSM) to locate inhomogeneities inside a homogeneous background and solve the DOT problem in both full and limited aperture cases. This new method is easy to implement and less expensive compu...
