CHAOTIC NEOCORTICAL DYNAMICS [PDF]

open access: yes, 2013
The first step of the sensory systems is to construct the meaning of the information they receive from the senses. They do this by generating random noise and then filtering the noise with adaptive filters. We simulate the operation with the solutions of matrices of ordinary differential equations that predict bifurcations between point and limit cycle

Density Dependent Predator Death Prevalence Chaos in a Tri-trophic Food Chain Model

open access: yesNonlinear Analysis, 2008
Ecological systems have all the properties to produce chaotic dynamics. To predict the chaotic behavior in an ecological system and its possible control mechanism is interesting.

Dynamic Regimes of El Niño Southern Oscillation and Influenza Pandemic Timing

open access: yesFrontiers in Public Health, 2017
El Niño southern oscillation (ENSO) dynamics has been shown to drive seasonal influenza dynamics. Severe seasonal influenza epidemics and the 2009–2010 pandemic were coincident with chaotic regime of ENSO dynamics.

A new approach to the treatment of Separatrix Chaos and its applications [PDF]

open access: yes, 2010
We consider time-periodically perturbed 1D Hamiltonian systems possessing one or more separatrices. If the perturbation is weak, then the separatrix chaos is most developed when the perturbation frequency lies in the logarithmically small or moderate ...

Bifurcation Scenarios of Neural Firing Patterns across Two Separated Chaotic Regions as Indicated by Theoretical and Biological Experimental Models

open access: yesAbstract and Applied Analysis, 2013
Nonlinear dynamics can be used to identify relationships between different firing patterns, which play important roles in the information processing.

Abrupt bifurcations in chaotic scattering : view from the anti-integrable limit [PDF]

open access: yes, 2013
Bleher, Ott and Grebogi found numerically an interesting chaotic phenomenon in 1989 for the scattering of a particle in a plane from a potential field with several peaks of equal height.

Chaotic Economic Dynamics [PDF]

open access: yes, 1990
AbstractThis collection of short essays provides an application of chaotic dynamics to economic systems. Each chapter presents several economic models incorporating differential (or difference) equations such as the Rössler equations, which exhibit a chaotic attractor.

Optimal Estimation and Sequential Channel Equalization Algorithms for Chaotic Communications Systems

open access: yesEURASIP Journal on Advances in Signal Processing, 2001
Many previously proposed communications systems based on chaos disregard common channel distortions and fail to work under realistic channel conditions.

High chaotic spiking rate in a closed loop semiconductor laser with optical feedback

open access: yesResults in Physics, 2016
We investigate experimentally and numerically the existence of fast chaotic spiking in the dynamics of a semiconductor laser with ac-coupled optical feedback.
