Entropy production from maximum entropy principle: A unifying approach
Entropy production is the crucial quantity characterizing irreversible phenomena and the second law of thermodynamics. Yet, a ubiquitous definition eludes consensus. Given that entropy production arises from incomplete access to information, in this Letter we use Jaynes' maximum entropy principle to establish a framework that brings together prominent ...

Fractal Structure and Entropy Production within the Central Nervous System
Our goal is to explore the relationship between two traditionally unrelated concepts, fractal structure and entropy production, evaluating both within the central nervous system (CNS).

Upper bound for quantum entropy production from entropy flux
Entropy production is a key quantity characterizing nonequilibrium systems. However, it can often be difficult to compute in practice, as it requires detailed information about the system and the dynamics it undergoes. This becomes even more difficult in the quantum domain, and if one is interested in generic nonequilibrium reservoirs, for which the ...

Spectral Entropy in a Boundary-Layer Flow
This article presents a comparison of the entropy production in a laminar and transitional boundary layer flow with the spectral entropy produced in a region of instability induced by an imposed periodic disturbance.

Radiative entropy production—lost heat into entropy [PDF]
Heat flow SQ of the First Law of Thermodynamics is expressed in terms of the entropy flow &Q/T) SQ = SIT(QIT)I = ~~(Q/~+(Q~~d~ where T&Q/T) denotes the energy equivalent of the entropy flow, and (Q/T)dT introduces the concept of lost heat into entropy production.

From Maximum Entropy to Maximum Entropy Production: A New Approach
Evidence from climate science suggests that a principle of maximum thermodynamic entropy production can be used to make predictions about some physical systems.

Between Waves and Diffusion: Paradoxical Entropy Production in an Exceptional Regime
The entropy production rate is a well established measure for the extent of irreversibility in a process. For irreversible processes, one thus usually expects that the entropy production rate approaches zero in the reversible limit.

Thermodynamic Hamiltonian and Entropy Production
The variational method holds considerable significance within mathematical and theoretical physics. Its importance stems from its capacity to characterise natural systems through physical quantities, irrespective of the chosen frame of reference.

The Character of Entropy Production in Rayleigh–Bénard Convection
In this study; the Rayleigh–Bénard convection model was established; and a great number of Bénard cells with different numbered vortexes were acquired by numerical simulation.

Game-theoretical approach to minimum entropy productions in information thermodynamics
In a situation where each player has control over the transition probabilities of each subsystem, we game-theoretically analyze the optimization problem of minimizing both the partial entropy production of each subsystem and a penalty for failing to ...
