Entropy and Entropy Production: Old Misconceptions and New Breakthroughs

Entropy, 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.

On the validity of entropy production principles for linear electrical circuits

, 2007
We discuss the validity of close-to-equilibrium entropy production principles in the context of linear electrical circuits. Both the minimum and the maximum entropy production principle are understood within dynamical fluctuation theory.

Crossed products and entropy of automorphisms

Journal of Functional Analysis, 2004
Let A be an exact C^*-algebra, let G be a locally compact group, and let (A,G, ) be a C*-dynamical system. Each automorphism _g induces a spatial automorphism Ad_{\lamba_g} on the reduced crossed product A\times_ G. In this paper we examine the question, first raised by E.

Entropy production of cyclic population dynamics

, 2010
Entropy serves as a central observable in equilibrium thermodynamics. However, many biological and ecological systems operate far from thermal equilibrium. Here we show that entropy production can characterize the behavior of such nonequilibrium systems.

Nonequilibrium quantum-impurities: from entropy production to information theory

, 2007
Nonequilibrium steady-state currents, unlike their equilibrium counterparts, continuously dissipate energy into their physical surroundings leading to entropy production and time-reversal symmetry breaking.

Thermodynamic efficiency and entropy production in the climate system [PDF]

, 2009
We present an outlook on the climate system thermodynamics. First, we construct an equivalent Carnot engine with efficiency and frame the Lorenz energy cycle in a macroscale thermodynamic context.

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

An Analysis of the Characteristics of Internal Flow Losses of Seawater Circulation Pumps in Nuclear Power Plants Based on the Entropy Production Theory

Energies
The seawater circulation pump represents the pump product with the largest flow rate within nuclear power plants. Its energy consumption accounts for a substantial portion of the energy consumed by nuclear power plants.

Entropy Production of Main-Sequence Stars

Entropy, 2015
The entropy production (inside the volume bounded by a photosphere) of main-sequence stars is calculated based on B–V photometry data. The entropy-production distribution function and the dependences of entropy production on temperature and luminosity ...
