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.

Pseudo-boundaries in discontinuous two-dimensional maps

TL;DR: In this paper, it was shown that pseudo-boundaries can also be found in discontinuous maps, i.e., chains of chains of islands which separate parts of the phase space and need to be crossed in order to move between the different subspaces.

The Synergic Role of Actomyosin Architecture and Biased Detachment in Muscle Energetics: Insights in Cross Bridge Mechanism beyond the Lever-Arm Swing

TL;DR: In this paper, the authors combined experimental measurements of in vitro sliding velocity based on DNA-origami built filaments carrying myosins with different lever arm length and Monte Carlo simulations based on a model which accounts for three basic components: (i) the geometrical hindrance, (ii) the mechano-sensing mechanism, and (iii) the biased kinetics for stretched or compressed motors.

Chemical Separation on Silver Nanorods Surface Monitored by TOF-SIMS

TL;DR: In this article, a possible chemical separation of a mixture of two compounds on the metal nanorods surface was introduced, which can be easily integrated into the micro/nanofluidic systems or chips and different detection systems can be applied.

Power-Stroke-Driven Muscle Contraction

TL;DR: In this article, a review of a recently developed approach to muscle contraction where myosin power stroke is interpreted as the main active mechanism is presented, which contributes to building a conceptual bridge between processive and non-processive motors.

The Fokker-Planck Equation: Methods of Solution and Applications

Hannes Risken
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.
