Estimating entropy production rates with first-passage processes [PDF]
We consider the problem of estimating the mean entropy production rate in a nonequilibrium process from the measurements of first-passage quantities associated with a single current.

Irreversible entropy production: From classical to quantum [PDF]
Entropy production is a key quantity in any finite-time thermodynamic process. It is intimately tied with the fundamental laws of thermodynamics, embodying a tool to extend thermodynamic considerations all the way to non-equilibrium processes. It is also

Estimating Entropy Production from Waiting Time Distributions. [PDF]
Living systems operate far from thermal equilibrium by converting the chemical potential of ATP into mechanical work to achieve growth, replication, or locomotion.

Characteristics of Cavitation Flow for a Regulating Valve Based on Entropy Production Theory
A regulating valve is a key control element in the coal liquefaction industry, whose flow field distribution is related to the entropy production. In order to make a quantitative evaluation of the energy loss in the cavitation flow and calculate the ...

The energy loss of the vertical axial flow pump device increases due to the unstable internal flow, which reduces the efficiency of the pump device and increases its energy consumption of the pump device.

Minimum entropy production, detailed balance and Wasserstein distance for continuous-time Markov processes [PDF]
We investigate the problem of minimizing the entropy production for a physical process that can be described in terms of a Markov jump dynamics. We show that, without any further constraints, a given time-evolution may be realized at arbitrarily small ...

Geometric decomposition of entropy production in out-of-equilibrium systems [PDF]
Two qualitatively different ways of driving a physical system out of equilibrium, time-dependent and non-conservative forcing, are reflected by the decomposition of the system’s entropy production into excess and housekeeping parts.

Model-Free Measurement of Local Entropy Production and Extractable Work in Active Matter. [PDF]
Time-reversal symmetry breaking and entropy production are universal features of nonequilibrium phenomena. Despite its importance in the physics of active and living systems, the entropy production of systems with many degrees of freedom has remained of ...

A Photon Force and Flow for Dissipative Structuring: Application to Pigments, Plants and Ecosystems
Through a modern derivation of Planck’s formula for the entropy of an arbitrary beam of photons, we derive a general expression for entropy production due to the irreversible process of the absorption of an arbitrary incident photon spectrum in material ...

Ecosystem entropy production is predicted to increase along ecological succession and approach a state of maximum entropy production, but few studies have bridged the gap between theory and data.
