Thermodynamics from relative entropy [PDF]
Phys. Rev. E 102, 052117 (2020), 2020 Thermodynamics is usually developed starting from entropy and the maximum entropy principle. We investigate here to what extent one can replace entropy with relative entropy which has several advantages, for example in the context of local quantum field theory.

BD entropy and Bernis–Friedman entropy [PDF]
Comptes Rendus. Mathématique, 2018 In this note, we propose in the full generality a link between the BD entropy introduced by D. Bresch andB. Desjardins for the viscous shallow-water equations and the Bernis-Friedman (called BF) dissipative entropyintroduced to study the lubrications equations. Dierent dissipative entropies are obtained playing with the dragterms on the viscous shallow

Strain-rate sensitivity of high-entropy alloys and its significance in deformation
Materials Research Letters, 2019 Strain-rate dependence in face centered cubic high entropy alloys still remains controversial despite extensive efforts on this topic. Strain-rate sensitivity reflects underlying thermally-activated deformation and the controversy boils down to the ...

Frontiers in Materials, 2022 Cr and Mn play intriguing roles in determining the magnetic properties of CoFeNi-based high-entropy alloys (HEA). In this study, we tune the stoichiometric Mn composition to systematically explore the magnetic properties of (CoCrFeNi)1−xMnx HEAs.

PLOS Genetics, 2015 ABSTRACTEpistasis is a key concept in the theory of adaptation. Indicators of epistasis are of interest for large system where systematic fitness measurements may not be possible. Some recent approaches depend on information theory. We show that considering shared entropy for pairs of loci can be misleading.

Divergence measures based on the Shannon entropy
IEEE Transactions on Information Theory, 1991 A novel class of information-theoretic divergence measures based on the Shannon entropy is introduced. Unlike the well-known Kullback divergences, the new measures do not require the condition of absolute continuity to be satisfied by the probability ...

Approximate entropy as a measure of system complexity.
Proceedings of the National Academy of Sciences of the United States of America, 1991 Techniques to determine changing system complexity from data are evaluated. Convergence of a frequently used correlation dimension algorithm to a finite value does not necessarily imply an underlying deterministic model or chaos.
