Statistical optimization for passive scalar transport: maximum entropy production versus maximum Kolmogorov–Sinai entropy [PDF]

open access: yesNonlinear Processes in Geophysics, 2015
We derive rigorous results on the link between the principle of maximum entropy production and the principle of maximum Kolmogorov–Sinai entropy for a Markov model of the passive scalar diffusion called the Zero Range Process.

Principle of Least Effort and Sentence Length in Public Speaking

open access: yesEntropy, 2021
The analysis of sentence lengths in the inaugural speeches of US presidents and the annual speeches of UK party leaders is carried out. Transcripts of the speeches are used, rather than the oral production.

Entropy production by evapotranspiration and its geographic variation

open access: yesSoil and Water Research, 2008
The hydrologic cycle is a system far from thermodynamic equilibrium that is characterized by its rate of entropy production in the climatological mean steady state.

Maximum entropy production: can it be used to constrain conceptual hydrological models? [PDF]

open access: yesHydrology and Earth System Sciences, 2013
In recent years, optimality principles have been proposed to constrain hydrological models. The principle of maximum entropy production (MEP) is one of the proposed principles and is subject of this study.

Entropy production and lost work for irreversible processes [PDF]

open access: yes, 2006
In this paper we analyse in depth the Lost Work in an irreversible process (i.e. IRREV REV Lost ) W =W -W . This quantity is also called ‘degraded energy’ or ‘Energy unavailable to do work’. Usually in textbooks one can find the relation Lost U W o TDS .

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 ...

Entropy production of soil hydrological processes and its maximisation [PDF]

open access: yesEarth System Dynamics, 2011
Hydrological processes are irreversible and produce entropy. Hence, the framework of non-equilibrium thermodynamics is used here to describe them mathematically.

An Introduction to the Non-Equilibrium Steady States of Maximum Entropy Spike Trains

open access: yesEntropy, 2019
Although most biological processes are characterized by a strong temporal asymmetry, several popular mathematical models neglect this issue. Maximum entropy methods provide a principled way of addressing time irreversibility, which leverages powerful ...

The Latent Maximum Entropy Principle [PDF]

open access: yes, 2002
We present an extension of Jaynes\u27 maximum entropy principle to handle latent variables. We use an EM algorithm that incorporates nested iterative scaling to approximately calculate maximum entropy solutions for this principle, and give a proof of its

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
