Entropy Production of Stars [PDF]

open access: yesEntropy, 2015
The entropy production (inside the volume bounded by a photosphere) of main-sequence stars, subgiants, giants, and supergiants is calculated based on B–V photometry data. A non-linear inverse relationship of thermodynamic fluxes and forces as well as an

A model of entropy production [PDF]

open access: yesScientific Reports
A key tenet of the Transactional Interpretation of Quantum Mechanics is the idea that photon absorption localizes the absorbing material system. In doing so, it measures the location of the absorber and hence reduces information entropy which in turn ...

Entropy Production in Exactly Solvable Systems

open access: yesEntropy, 2020
The rate of entropy production by a stochastic process quantifies how far it is from thermodynamic equilibrium. Equivalently, entropy production captures the degree to which global detailed balance and time-reversal symmetry are broken.

Continuous Monitoring of Entropy Production and Entropy Flow in Humans Exercising under Heat Stress [PDF]

open access: yesEntropy, 2023
Complex living systems, such as the human organism, are characterized by their self-organized and dissipative behaviors, where irreversible processes continuously produce entropy internally and export it to the environment; however, a means by which to ...

Foraging Dynamics and Entropy Production in a Simulated Proto-Cell [PDF]

open access: yesEntropy, 2022
All organisms depend on a supply of energetic resources to power behavior and the irreversible entropy-producing processes that sustain them. Dissipative structure theory has often been a source of inspiration for better understanding the thermodynamics ...

Entropy Production in Stochastics [PDF]

open access: yesEntropy, 2017
While the modern definition of entropy is genuinely probabilistic, in entropy production the classical thermodynamic definition, as in heat transfer, is typically used.

Optimizing Our Patients’ Entropy Production as Therapy? Hypotheses Originating from the Physics of Physiology

open access: yesEntropy, 2020
Understanding how nature drives entropy production offers novel insights regarding patient care. Whilst energy is always preserved and energy gradients irreversibly dissipate (thus producing entropy), increasing evidence suggests that they do so in the ...

Beyond the Second Law: Darwinian Evolution as a Tendency for Entropy Production to Increase [PDF]

open access: yesEntropy
There is much confusion about the apparent opposition between Darwinian evolution and the second law of thermodynamics. Both entropy and entropy production play more fundamental roles in the origin of life and Darwinian evolution than is generally ...

Geometrical aspects of entropy production in stochastic thermodynamics based on Wasserstein distance

open access: yesPhysical Review Research, 2021
We study a relationship between optimal transport theory and stochastic thermodynamics for the Fokker-Planck equation. We show that the lower bound on the entropy production is the action measured by the path length of the L^{2}-Wasserstein distance ...

Entropy and Entropy Production: Old Misconceptions and New Breakthroughs [PDF]

open access: yesEntropy, 2013
Persistent misconceptions existing for dozens of years and influencing progress in various fields of science are sometimes encountered in the scientific and especially, the popular-science literature.
