Information Entropy in Chemistry: An Overview

open access: yesEntropy, 2021
Basic applications of the information entropy concept to chemical objects are reviewed. These applications deal with quantifying chemical and electronic structures of molecules, signal processing, structural studies on crystals, and molecular ensembles ...

Entropy: From Thermodynamics to Information Processing

open access: yesEntropy, 2021
Entropy is a concept that emerged in the 19th century. It used to be associated with heat harnessed by a thermal machine to perform work during the Industrial Revolution.

On integrating size and shape distributions into a spatio-temporal information entropy framework [PDF]

open access: yes, 2019
Understanding the structuration of spatio-temporal information is a common endeavour to many disciplines and application domains, e.g., geography, ecology, urban planning, epidemiology.

Information Entropy of Liquid Metals [PDF]

open access: yesThe Journal of Physical Chemistry B, 2018
Correlations reduce the configurational entropies of liquids below their ideal gas limits. By means of first principles molecular dynamics simulations, we obtain accurate pair correlation functions of liquid metals, then subtract the mutual information content of these correlations from the ideal gas entropies to predict the absolute entropies over a ...

Information and entropy [PDF]

open access: yesPhysical Review E, 1993
The Landauer cost for erasing information demands that information about a physical system be included in the total entropy, as proposed by Zurek [Nature 341, 119 (1989); Phys. Rev. A 40, 4731 (1989)]. A consequence is that most system states-either classical phase-space distributions or quantum pure states-have total entropy much larger than thermal ...

Information and Entropy [PDF]

open access: yesAIP Conference Proceedings, 2007
What is information? Is it physical? We argue that in a Bayesian theory the notion of information must be defined in terms of its effects on the beliefs of rational agents. Information is whatever constrains rational beliefs and therefore it is the force that induces us to change our minds.

Information, Genetics and Entropy

open access: yesPrincipia: An International Journal of Epistemology, 2015
The consolidation of the informational paradigm in molecular biology research concluded on a system to convert the epistemic object into an operational technological object and a stable epistemic product.
