Configurational entropy in Chaplygin gas models [PDF]
The European Physical Journal Plus, 2021 The present work employs the Linder parametrization of a constant growth index \cite{linder/index} to investigate the evolution of growth rate of clustering and the dissipation of configurational entropy in some of the most widely studied Chaplygin gas models, such as the generalized Chaplygin gas and the modified Chaplygin gas. The model parameters of

Tsallis Entropy for Cross-Shareholding Network Configurations [PDF]
Entropy, 2020 In this work, we develop the Tsallis entropy approach for examining the cross-shareholding network of companies traded on the Italian stock market. In such a network, the nodes represent the companies, and the links represent the ownership. Within this context, we introduce the out-degree of the nodes—which represents the diversification—and the in ...

Configurational entropy of glass-forming liquids [PDF]
The Journal of Chemical Physics, 2019 The configurational entropy is one of the most important thermodynamic quantities characterizing supercooled liquids approaching the glass transition. Despite decades of experimental, theoretical, and computational investigation, a widely accepted definition of the configurational entropy is missing, its quantitative characterization remains fraught ...

Entropic Stabilization of Cas4 Protein SSO0001 Predicted with Popcoen
Entropy, 2018 Popcoen is a method for configurational entropy estimation of proteins based on machine-learning. Entropy is predicted with an artificial neural network which was trained on simulation trajectories of a large set of representative proteins.

Ligand configurational entropy and protein binding [PDF]
Proceedings of the National Academy of Sciences, 2007 The restriction of a small molecule's motion on binding to a protein causes a loss of configurational entropy, and thus a penalty in binding affinity. Some energy models used in computer-aided ligand design neglect this entropic penalty, whereas others account for it based on an expected drop in the number of accessible rotamers upon ...

Configurational entropy of anti-de Sitter black holes
Physics Letters B, 2017 Recent studies indicate that the configurational entropy is an useful tool to investigate the stability and (or) the relative dominance of states for diverse physical systems. Recent examples comprise the connection between the variation of this quantity

Configurational entropy of native proteins
Biophysical Journal, 1987 Simulations of the residual configurational entropy of a protein in the native state suggest that it is nearly an order of magnitude larger than the entropy of denaturation. The implications of this result are discussed.

Configurational entropy in f(T) gravity [PDF]
The European Physical Journal Plus, 2020 The evolution of the configurational entropy of the universe relies on the growth rate of density fluctuations and on the Hubble parameter. In this work, I present the evolution of configurational entropy for the power-law $f(T)$ gravity model of the form $f(T) = (-T)^ b$, where, $ = (6 H_{0}^{2})^{(1-s)}\frac{ _{P_{0}}}{2 s -1}$ and $b$ a free ...

Configurational entropy of polydisperse supercooled liquids [PDF]
The Journal of Chemical Physics, 2018 We propose a computational method to measure the configurational entropy in generic polydisperse glass-formers. In particular, our method resolves issues related to the diverging mixing entropy term due to a continuous polydispersity. The configurational entropy is measured as the difference between the well-defined fluid entropy and a more problematic

Entropy, 2018 We determined the entropy of high entropy alloys by investigating single-crystalline nickel and five high entropy alloys: two fcc-alloys, two bcc-alloys and one hcp-alloy. Since the configurational entropy of these single-phase alloys differs from alloys
