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 ...

An estimation of the logarithmic timescale in an ergodic dynamics
, 2017 An estimation of the logarithmic timescale in quantum systems having an ergodic dynamics in the semiclassical limit of quasiclassical large parameters, is presented.

, 2006 We propose a method for computing the Kolmogorov-Sinai (KS) entropy of chaotic systems. In this method, the KS entropy is expressed as a statistical average over the canonical ensemble for a Hamiltonian with many ground states.

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

On the nonlinearity of quantum dynamical entropy
, 2018 Linearity of a dynamical entropy means that the dynamical entropy of the n-fold composition of a dynamical map with itself is equal to n times the dynamical entropy of the map for every positive integer n.

Hyperbolicity and Southern Hemisphere Persistent Synoptic Events
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.Abstract Predicting the occurrence of coherent blocking structures in synoptic weather systems remains a challenging problem that has taxed the numerical weather prediction community for decades. The underlying factor behind this difficulty is the so‐called “loss of hyperbolicity” known to be linked with the alignment of dynamical vectors ...

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.

MedComm – Future Medicine, Volume 4, Issue 1, March 2025.This first retrospective cohort study on long‐term in‐stent chronic total occlusion (IS‐CTO) outcomes after prior drug‐eluting stent (DES) found that, although drug‐coated balloon (DCB) offered attractive short‐to‐midterm results by avoiding extra metallic layers, it had higher adverse outcomes than DES long‐term.

Alzheimer's &Dementia, Volume 21, Issue 1, January 2025.Abstract INTRODUCTION Alzheimer's disease (AD) co‐pathology with Lewy bodies (LB) is frequent and influences clinical manifestations and outcomes. Its significance in primary age‐related tauopathy (PART) is unknown. We investigated the influence of LB on cognition and brain atrophy in AD and PART.
