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.

t-Entropy formulae for concrete classes of transfer operators
Журнал Белорусского государственного университета: Математика, информатика, 2019 t-Entropy is a principal object of the spectral theory of operators, generated by dynamical systems, namely, weighted shift operators and transfer operators.

A scalable distribution network risk evaluation framework via symbolic dynamics. [PDF]
PLoS ONE, 2015 Evaluations of electric power distribution network risks must address the problems of incomplete information and changing dynamics. A risk evaluation framework should be adaptable to a specific situation and an evolving understanding of risk.This study ...

Association between body mass index, obesity, and vulvar cancer recurrence
International Journal of Gynecology &Obstetrics, Volume 170, Issue 1, Page 268-273, July 2025.Abstract Objective The objective of this paper is to study the association between obesity and tumor recurrence in patients with vulvar cancer. Methods This is a retrospective study including vulvar cancer patients from 2003 to 2022. Our primary outcome was progression‐free survival (PFS) stratified by status of obesity, defined as body mass index (BMI)

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

The Journal of Clinical Hypertension, Volume 27, Issue 7, July 2025.ABSTRACT Hypertension is the most important contributor to the development of cardiovascular disease. The objective of the Bring it Down program was to examine the reach and effectiveness of linkage to primary care via community health workers (CHWs) to improve blood pressure control among people with undiagnosed or uncontrolled hypertension.

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.

Superdensity operators for spacetime quantum mechanics
Journal of High Energy Physics, 2018 We introduce superdensity operators as a tool for analyzing quantum information in spacetime. Superdensity operators encode spacetime correlation functions in an operator framework, and support a natural generalization of Hilbert space techniques and ...

On the origin and development of some notions of entropy
Topological Algebra and its Applications, 2015 Discrete dynamical systems are given by the pair (X, f ) where X is a compact metric space and f : X → X a continuous maps. During years, a long list of results have appeared to precise and understand what is the complexity of the systems.
