TL;DR: A new method is presented to measure the association rate k(on) of ligand-receptor pairs incorporated into lipid membranes and it is found that the k( on) for the interaction of biotin with neutravidin is larger than that for integrin binding to RGD or sialyl Lewis(x) to E-selectin.

TL;DR: For a three-state Markov system in a stationary state, it is shown in this paper that it is possible to discriminate between an equilibrium state and a nonequilibrium steady state by calculating the full phase diagram.

TL;DR: By considering subexponential contributions in large deviation theory, this approach determines the fine structure in the probability distribution of the observable displacement of a bead coupled to a molecular motor, revealing a discrete symmetry of this distribution for which hidden degrees of freedom lead to a periodic modulation of the slope typically associated with the fluctuation theorem.

TL;DR: In this article, the violation of the fluctuation-dissipation theorem (FDT) is connected to breaking detailed balance, by measuring the velocity with respect to the local mean velocity.

TL;DR: Surprisingly, this approach reveals that the interaction with the passive obstacle can mediate cooperativity between otherwise noninteracting active particles, which enhances the extracted power per active particle significantly.
