Growth but Not Corticosterone, Oxidative Stress, or Telomere Length Is Negatively Affected by Microplastic Exposure in a Filter‐Feeding Amphibian

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 8, Page 857-869, October 2025.
ABSTRACT Microplastics (MPs) are of increasing global concern for species inhabiting aquatic habitats. However, the mechanisms behind animal responses to MPs still require comprehensive exploration. Amphibians are the most threatened vertebrate group with most species having a complex life cycle, commonly with an aquatic larval stage.

Production rate of the coarse-grained Gibbs entropy and the Kolmogorov-Sinai entropy: A real connection?

, 2005
We discuss the connection between the Kolmogorov-Sinai entropy h KS and the production rate of the coarse-grained Gibbs entropy r G. Detailed numerical computations show that the (often-accepted) identification of the two quantities does not hold in ...

Quantifying partition-based Kolmogorov-Sinai Entropy on Heart Rate Variability: a young vs. elderly study

, 2021
In the last decades, a considerable effort has been devoted to quantify complexity in physiological time series, with a particular focus on heart rate variability (HRV).

DETERMINISTIC CHARACTER OF CHANGES OF THE CASPIAN SEA LEVEL AND ITS QUANTITATIVE PARAMETERS

Юг России: экология, развитие, 2014
. The results of determination of parameters of dynamics of Caspian Sea level changes were studied. We determined quantities and dimensions of the phase space and the attractor, we calculated exponents of Lyapunov and assessed value of Kolmogorov – Sinai

Predictability of breathing parameters during cardiopulmonary exercise testing using entropy measurements

Physiological Reports, Volume 13, Issue 19, October 2025.
Abstract Erratic breathing at rest and during exercise has been described in patients with dysfunctional breathing (DB). Sample entropy (SampEn) and approximate entropy (ApEn) were developed to assess the predictability of parameters in time series data. However, SampEn and ApEn were developed for data without trends.

Maximum Kolmogorov-Sinai Entropy Versus Minimum Mixing Time in Markov Chains

, 2017
International audienceWe establish a link between the maximization of Kolmogorov Sinai entropy (KSE)and the minimization of the mixing time for general Markov chains. Since the maximisation ofKSE is analytical and easier to compute in general than mixing

Application of the Acoustic Emission Method and Kolmogorov-Sinai Metric Entropy in Determining the Yield Point in Aluminium Alloy

, 2020
This study analyzes the possibility of applying the acoustic emission method (AE) and the Kolmogorov-Sinai (K-S) metric entropy phenomenon in determining the structural changes that take place within the EN AW 7020 aluminum alloy.

Multi-delay complexity collapse

Physical Review Research, 2020
Increasing the number of delays in nonlinear dynamical systems is generally assumed to lead to higher complexity, but “distributed delay” systems with an infinite number of delays to lesser complexity.

Cognitive brain lateralization through neurovascular coupling in healthy subjects: A statistical complexity analysis

Physiological Reports, Volume 13, Issue 15, August 2025.
Abstract Human sensory, cognitive, and motor processes often result in asymmetric cerebral hemisphere activation, observable through neurovascular coupling (NVC). Brain lateralization enables simultaneous performance of distinct functions, enhancing cognitive capacity.
