TLDR
In this paper, the authors considered a Brownian particle in a periodic potential under heavy damping and showed that if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed.Abstract:
We consider a Brownian particle in a periodic potential under heavy damping. The second law forbids it from displaying any net drift speed, even if the symmetry of the potential is broken. But if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed. Thus, broken symmetry and time correlations are sufficient ingredients for transport.read more

A Historical Perspective of Actin Assembly and Its Interactions
TL;DR: This work has shown that the reverse transformation from F to G was not associated with rephosphorylation of bound ADP; G-actin released ADP and bound new ATP in solution.

Sorting of brownian rods by the use of an asymmetric potential.
TL;DR: A two stage sorting process is used to isolate particles with specific dimensions, with acceptable sorting times as well as realizable potential barrier lengths, using a switching asymmetric periodic potential.

Spontaneous rectification and absolute negative mobility of inertial Brownian particles induced by Gaussian potentials in steady laminar flows.
TL;DR: In this article, the authors studied the transport of inertial Brownian particles in steady laminar flows in the presence of two-dimensional Gaussian potentials and found that the transport is sensitively dependent on the external constant force and the Gaussian capacity.

Current Reversal in a Flashing Correlation Ratchet
TL;DR: In this paper, a flashing correlation ratchet model is proposed, in which the transport of Brownian particles driven by additive colored noise of Ornstein-Uhlenbeck type in a flashing ratchet is studied by Monte Carlo simulation.

The Fokker-Planck Equation: Methods of Solution and Applications
TL;DR: In this paper, the Fokker-Planck Equation for N Variables (FPE) was extended to N = 1 variable and N = 2 variables, where N is the number of variables in the system.
