Ascertaining when a basin is Wada: the merging method

open access: yesScientific Reports, 2018
Trying to imagine three regions separated by a unique boundary seems a difficult task. However, this is exactly what happens in many dynamical systems showing Wada basins.

In Extraction and Analysis of Methadone in Exhaled Breath Condensate Using a Validated LC-UV Method; Khoubnasabjafari et al, J Pharm Pharm Sci 18(2) 207-219, 2015, all methadone concentrations should read “µg/mL” rather than “µg/L”.

Temperature chaos is a non-local effect [PDF]

open access: yes, 2016
Temperature chaos plays a role in important effects, like for example memory and rejuvenation, in spin glasses, colloids, polymers. We numerically investigate temperature chaos in spin glasses, exploiting its recent characterization as a rare-event ...

Neimark-Sacker Bifurcation in a Discrete-Time Financial System

open access: yesDiscrete Dynamics in Nature and Society, 2010
A discrete-time financial system is proposed by using forward Euler scheme. Based on explicit Neimark-Sacker bifurcation (also called Hopf bifurcation for map) criterion, normal form method and center manifold theory, the system's existence, stability ...

Wigner chaos and the fourth moment [PDF]

open access: yes, 2012
We prove that a normalized sequence of multiple Wigner integrals (in a fixed order of free Wigner chaos) converges in law to the standard semicircular distribution if and only if the corresponding sequence of fourth moments converges to 2, the fourth ...

Projective Synchronization of N-Dimensional Chaotic Fractional-Order Systems via Linear State Error Feedback Control

open access: yesDiscrete Dynamics in Nature and Society, 2012
Based on linear feedback control technique, a projective synchronization scheme of N-dimensional chaotic fractional-order systems is proposed, which consists of master and slave fractional-order financial systems coupled by linear state error variables ...

Bubble Relaxation Dynamics in Homopolymer DNA Sequences

open access: yesMolecules, 2023
Understanding the inherent timescales of large bubbles in DNA is critical to a thorough comprehension of its physicochemical characteristics, as well as their potential role on helix opening and biological function.

A boundary integral formalism for stochastic ray tracing in billiards [PDF]

open access: yes, 2014
Determining the flow of rays or non-interacting particles driven by a force or velocity field is fundamental to modelling many physical processes. These include particle flows arising in fluid mechanics and ray flows arising in the geometrical optics ...
