Logical entropy of dynamical systems in product MV-algebras and general scheme

open access: yesAdvances in Difference Equations, 2019
The present paper is aimed at studying the entropy of dynamical systems in product MV-algebras. First, by using the concept of logical entropy of a partition in a product MV-algebra introduced and studied by Markechová et al.

Entropy of Fuzzy Partitions and Entropy of Fuzzy Dynamical Systems

open access: yesEntropy, 2016
In the paper we define three kinds of entropy of a fuzzy dynamical system using different entropies of fuzzy partitions. It is shown that different definitions of the entropy of fuzzy partitions lead to different notions of entropies of fuzzy dynamical ...

Investigation of Early Warning Indexes in a Three-Dimensional Chaotic System with Zero Eigenvalues

open access: yesEntropy, 2020
A rare three-dimensional chaotic system with all eigenvalues equal to zero is proposed, and its dynamical properties are investigated. The chaotic system has one equilibrium point at the origin.

Maximum Entropy Production vs. Kolmogorov-Sinai Entropy in a Constrained ASEP Model

open access: yesEntropy, 2014
The asymmetric simple exclusion process (ASEP) has become a paradigmatic toy-model of a non-equilibrium system, and much effort has been made in the past decades to compute exactly its statistics for given dynamical rules.

Quantum Dynamical Entropies and Gács Algorithmic Entropy

open access: yesEntropy, 2012
Several quantum dynamical entropies have been proposed that extend the classical Kolmogorov–Sinai (dynamical) entropy. The same scenario appears in relation to the extension of algorithmic complexity theory to the quantum realm.

LL‐37 IgG levels are associated with clinical characteristics and T follicular cell response in acute coronary syndrome in adults

open access: yesPhysiological Reports, Volume 14, Issue 12, June 2026.
Abstract Elevated LL‐37 IgG levels are implicated in inflammatory conditions and immune complexes formed with LL‐37 potentially propagate immunothrombosis in acute coronary syndrome (ACS). The reported binding of LL‐37 to LDL may be relevant in this context given that LDL autoantibodies are implicated in ACS risk. In this report, three distinct cohorts

Information Dynamics in Complex Systems Negates a Dichotomy between Chance and Necessity

open access: yesInformation, 2020
Entropy increases in the execution of linear physical processes. At equilibrium, all uncertainty about the future is removed and information about the past is lost.

Prognostic Implication of CYP2C19 Genotype According to Clinical Risk Stratification After Drug‐Eluting Stent Implantation

open access: yesClinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 928-941, April 2026.
From the nationwide multicenter consortium, 8,163 patients undergoing drug‐eluting stent implantation were classified according to the presence of the CYP2C19 loss‐of‐function (LoF) allele: rapid or normal metabolizers (RMs/NMs) vs. intermediate or poor metabolizers (IMs/PMs), and clinical risk was stratified using the CHADS‐P2A2RC and TRS 2°P scores ...

Toward an Analytical Solution of the Liouville Equation via Data‐Driven Methods: Applications to Ensemble Forecasting

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Solving probabilistic weather forecasts is challenging due to computational constraints and the nonlinear nature of Earth atmosphere. This study proposes a proof‐of‐concept to address these challenges by solving the Liouville equation, that is, the analytical solution for probabilistic forecasts, with data‐driven method.

Acoustic Emission and K-S Metric Entropy as Methods for Determining Mechanical Properties of Composite Materials

open access: yesSensors, 2020
Due to the unique properties of polymer composites, these materials are used in many industries, including shipbuilding (hulls of boats, yachts, motorboats, cutters, ship and cooling doors, pontoons and floats, torpedo tubes and missiles, protective ...
