Phys Rev E
. 2024 Oct;
110(3):L032202.
PMID: 39425412
We use Clifford's geometric algebra to extend the Stuart-Landau system to dimensions D>2 and give an exact solution of the oscillator equations in the general case. At the supercritical Hopf...

Phys Rev E
. 2023 Aug;
108(1-1):014209.
PMID: 37583223
Phase slips are a typical dynamical behavior in coupled oscillator systems: the route to phase synchrony is characterized by intervals of constant phase difference interrupted by abrupt changes in the...

Chaos
. 2022 Dec;
32(11):113138.
PMID: 36456346
We consider a system of coupled nonlinear oscillators in which the interaction is modulated by a measure of the similarity between the oscillators. Such a coupling is common in treating...

. 2022 Feb;
32(1):013106.
PMID: 35105121
Understanding the asymptotic behavior of a dynamical system when system parameters are varied remains a key challenge in nonlinear dynamics. We explore the dynamics of a multistable dynamical system (the...

iScience
. 2021 Oct;
24(10):103199.
PMID: 34703995
We study a population-based cellular model that starts from a single stem cell that divides stochastically to give rise to either daughter stem cells or differentiated daughter cells. There are...

Sci Rep
. 2021 Jan;
11(1):2349.
PMID: 33504910
We study a minimal model of the stress-driven p53 regulatory network that includes competition between active and mutant forms of the tumor-suppressor gene p53. Depending on the nature and level...

Phys Rev E
. 2018 Sep;
98(2-1):022212.
PMID: 30253578
Stuart-Landau oscillators can be coupled so as to either preserve or destroy the rotational symmetry that the uncoupled system possesses. We examine some of the simplest cases of such couplings...

Phys Rev E
. 2018 Jan;
96(6-1):062203.
PMID: 29347357
We investigate the dynamics of coupled identical chaotic Lorenz oscillators just above the subcritical Hopf bifurcation. In the absence of coupling, the motion is on a strange chaotic attractor and...

. 2016 Jul;

PMID: 27368783
Spike-time correlations of neighbouring neurons depend on their intrinsic firing properties as well as on the inputs they share. Studies have shown that periodically firing neurons, when subjected to random...

Chaos
. 2016 Jul;
26(6):063111.
PMID: 27368776
We study the multistability that results when a chaotic response system that has an invariant symmetry is driven by another chaotic oscillator. We observe that there is a transition from...
