Geometric and dynamic perspectives on phase-coherent and noncoherent chaos [PDF]
Statistically distinguishing between phase-coherent and noncoherent chaotic dynamics from time series is a contemporary problem in nonlinear sciences.

Optical chaos in nonlinear photonic crystals [PDF]
We examine a spatial evolution of lightwaves in a nonlinear photonic crystal with a quadratic nonlinearity when simultaneously a second harmonic and a sum-frequency generation are quasi-phase-matched. We find the conditions of a transition to Hamiltonian

Linear And Nonlinear Arabesques: A Study Of Closed Chains Of Negative 2-Element Circuits [PDF]
In this paper we consider a family of dynamical systems that we call "arabesques", defined as closed chains of 2-element negative circuits. An $n$-dimensional arabesque system has $n$ 2-element circuits, but in addition, it displays by construction, two $

Complexity without chaos: Plasticity within random recurrent networks generates robust timing and motor control [PDF]
It is widely accepted that the complex dynamics characteristic of recurrent neural circuits contributes in a fundamental manner to brain function. Progress has been slow in understanding and exploiting the computational power of recurrent dynamics for ...

Data assimilation in slow-fast systems using homogenized climate models [PDF]
A deterministic multiscale toy model is studied in which a chaotic fast subsystem triggers rare transitions between slow regimes, akin to weather or climate regimes.

Fractal Measures and Nonlinear Dynamics of Overcontact Binaries [PDF]
Overcontact binary stars are systems of two stars where the component stars are in contact with each other. This implies that they share a common envelope of gas.

While most models of randomly connected networks assume nodes with simple dynamics, nodes in realistic highly connected networks, such as neurons in the brain, exhibit intrinsic dynamics over multiple timescales.

Characteristics of in-out intermittency in delay-coupled FitzHugh-Nagumo oscillators
We analyze a pair of delay-coupled FitzHugh-Nagumo oscillators exhibiting in-out intermittency as a part of the generating mechanism of extreme events.

Simple model of bouncing ball dynamics: displacement of the table assumed as quadratic function of time [PDF]
Nonlinear dynamics of a bouncing ball moving in gravitational field and colliding with a moving limiter is considered. Displacement of the limiter is a quadratic function of time.

Testing For Nonlinearity Using Redundancies: Quantitative and Qualitative Aspects
A method for testing nonlinearity in time series is described based on information-theoretic functionals -- redundancies, linear and nonlinear forms of which allow either qualitative, or, after incorporating the surrogate data technique, quantitative ...
