Definition of a linear equivalent model for a non-linear system with impacts [PDF]
, 2012 Modal characteristics of non-linear system are typically studied through response to harmonic excitation and using various definitions of non-linear modes. However, few results are available for systems under broadband excitation.

Comment on Dynamical Randomness in Quantum Systems [PDF]
Progress of Theoretical Physics Supplement, 1994 We propose a mechanism by which dynamical randomness may appear in many-body systems without sensitivity to initial conditions. We characterize dynamical randomness using the Kolmogorov-Sinai (KS) entropy per unit time and its 1987 quantum extension by Connes, Narnhofer, and Thirring (CNT).

Multiplicative ergodic theorem for a non-irreducible random dynamical system
, 2020 We study the asymptotic properties of the trajectories of a discrete-time random dynamical system in an infinite-dimensional Hilbert space. Under some natural assumptions on the model, we establish a multiplica-tive ergodic theorem with an exponential ...

A SHADOWING LEMMA FOR RANDOM DYNAMICAL SYSTEMS
Journal of Applied Analysis & Computation, 2021 Summary: This paper proves a shadowing lemma for the random dynamical systems generated by a class of random parabolic equations. We propose random versions of Newton's method and solution-tracing theory to obtain our main theorem. This result applies to \(C^1\) random dynamical systems on Banach space without assuming the corresponding map to be a ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Random Attractors of Stochastic Three-Component Reversible Gray-Scott System on Unbounded Domains
Abstract and Applied Analysis, 2012 The existence of a pullback random attractor is established for a stochastic three-component reversible Gray-Scott system on unbounded domains. The Gray-Scott system is recast as a random dynamical system and asymptotic compactness which is illustrated ...

A Free Energy Principle for Biological Systems
Entropy, 2012 This paper describes a free energy principle that tries to explain the ability of biological systems to resist a natural tendency to disorder. It appeals to circular causality of the sort found in synergetic formulations of self-organization (e.g., the ...
