Performance- and stimulus-dependent oscillations in monkey prefrontal cortex during short-term memory [PDF]

, 2009
Short-term memory requires the coordination of sub-processes like encoding, retention, retrieval and comparison of stored material to subsequent input. Neuronal oscillations have an inherent time structure, can effectively coordinate synaptic integration

Current-driven ion-acoustic and potential-relaxation instabilities excited in plasma plume during electron beam welding

AIP Advances, 2014
Many papers have sought correlations between the parameters of secondary particles generated above the beam/work piece interaction zone, dynamics of processes in the keyhole, and technological processes.

Quasi-Toroidal Oscillations in Rotating Relativistic Stars

, 1997
Quasi-toroidal oscillations in slowly rotating stars are examined in the framework of general relativity. The oscillation frequency to first order of the rotation rate is not a single value even for uniform rotation unlike the Newtonian case.

Relaxation oscillations in a class of predator–prey systems [PDF]

, 2003
We consider a class of three-dimensional, singularly perturbed predator–prey systems having two predators competing exploitatively for the same prey in a constant environment.

On the Limit Cycles of a Class of Planar Singular Perturbed Differential Equations

The Scientific World Journal, 2014
Relaxation oscillations of two-dimensional planar singular perturbed systems with a layer equation exhibiting canard cycles are studied. The canard cycles under consideration contain two turning points and two jump points.

Relaxation oscillations and frequency entrainment in quantum mechanics

, 2020
Frequency entrainment of continuous-variable oscillators has to date been restrained to the weakly nonlinear regime. Here we overcome this bottleneck and extend frequency entrainment of quantum continuous-variable oscillators to arbitrary nonlinearities.

Nonlinear dynamics and stability analysis of locally active Mott memristors using a physics-based compact model

Frontiers in Materials
Locally active memristors (LAMs) are a class of emerging nonlinear dynamic circuit elements that hold promise for scalable yet biomimetic neuromorphic circuits. Starting from a physics-based compact model, we performed small-signal linearization analyses

ON PERIODIC ORBITS OF RELAXATION OSCILLATIONS

Taiwanese Journal of Mathematics, 2002
Two nonlinear oscillators of relaxation type are studied, namely the singularly perturbed van der Pol oscillator and a Lotka-Volterra system. The aim of this work is to provide descriptions of periodic orbits governed by these equations in terms of two inverse functions of \(x \exp x\).
