Phytoplankton Temporal Strategies Increase Entropy Production in a Marine Food Web Model

Entropy, 2020
We develop a trait-based model founded on the hypothesis that biological systems evolve and organize to maximize entropy production by dissipating chemical and electromagnetic free energy over longer time scales than abiotic processes by implementing ...

Bias Analysis in Entropy Estimation

, 2004
We consider the problem of finite sample corrections for entropy estimation. New estimates of the Shannon entropy are proposed and their systematic error (the bias) is computed analytically.

Neuronal entropy depends on the level of alertness in the parkinsonian Globus Pallidus in vivo

Frontiers in Neurology, 2014
A new working hypothesis of Parkinson's disease proposes to focus on the central role of entropy increase in the Basal Ganglia in movement disorders. The conditions necessary for entropy increase in vivo are, however, still not fully described.

Entropy Could Quantify Brain Activation Induced by Mechanical Impedance-Restrained Active Arm Motion: A Functional NIRS Study

Entropy, 2022
Brain activation has been used to understand brain-level events associated with cognitive tasks or physical tasks. As a quantitative measure for brain activation, we propose entropy in place of signal amplitude and beta value, which are widely used, but ...

Beyond the Second Law: Darwinian Evolution as a Tendency for Entropy Production to Increase

Entropy
There is much confusion about the apparent opposition between Darwinian evolution and the second law of thermodynamics. Both entropy and entropy production play more fundamental roles in the origin of life and Darwinian evolution than is generally ...

Quantum Measurement and Entropy Production

, 2000
We study the time evolution of a quantum system without classical counterpart, undergoing a process of entropy increase due to the environment influence.

Preliminary study of thermal density distribution and entropy analysis during cycling exercise stress test using infrared thermography

Scientific Reports, 2022
Considerable differences related to the results of temperature changes acquired during exercise exist, and in many cases, these lead to poor correlation with physiological variables.
