TL;DR: Efficiency and, in particular, efficiency at maximum power can be discussed systematically beyond the linear response regime for two classes of molecular machines, isothermal ones such as molecular motors, and heat engines such as thermoelectric devices, using a common framework based on a cycle decomposition of entropy production.

TL;DR: In this article, the authors describe the systematic physical theory developed to understand the static and dynamic aspects of membrane and vesicle configurations, and the preferred shapes arise from a competition between curvature energy which derives from the bending elasticity of the membrane, geometrical constraints such as fixed surface area and fixed enclosed volume, and a signature of the bilayer aspect.

TL;DR: The integrated sum of both Delatas(tot) is shown to obey a fluctuation theorem (exp([-Deltas( tot) = 1 for arbitrary initial conditions and arbitrary time-dependent driving over a finite time interval)).

TL;DR: Vesicle shapes of low energy are studied for two variants of a continuum model for the bending energy of the bilayer, which lead to different predictions for typical trajectories, such as budding trajectories or oblate-stomatocyte transitions.

TL;DR: It is shown quite generally that, in a steady state, the dispersion of observables, like the number of consumed or produced molecules or thenumber of steps of a motor, is constrained by the thermodynamic cost of generating it.
