A modified version of the Ginzburg-Landau equation is introduced which accounts for asymmetric couplings between neighbors sites on a one-dimensional lattice, with periodic boundary conditions. The drift term which reflects the imposed microscopic asymmetry seeds a generalized class of instabilities, reminiscent of the Benjamin-Feir type. The uniformly synchronized solution is spontaneously destabilized outside the region of parameters classically associated to the Benjamin-Feir instability…

Desynchronization and pattern formation in a noisy feed-forward oscillator network.
TLDR
Noise assisted instability, ultimately vehiculated and amplified by the non-normal nature of the imposed couplings, eventually destabilizes also this second attractor, which yields spatiotemporal patterns, which cannot be anticipated by a conventional linear stability analysis.
Primary and secondary instabilities of the Mixed mode solution in a reaction diffusion system near the codimension-two Turing-Hopf point
Abstract Space-time structures near the codimension-two Turing-Hopf point (CTHP) that combine a spatial pattern with temporal oscillations are studied for a particular reaction diffusion (RD) system,
Desynchronization and pattern formation in a noisy feedforward oscillators network
We consider a one-dimensional directional array of diffusively coupled oscillators. They are perturbed by the injection of a small additive noise, typically orders of magnitude smaller than the

TLDR
The logistic map, a canonical one-dimensional system exhibiting surprisingly complex and aperiodic behavior, is modeled as a function of its chaotic parameter, and the progression through period-doubling bifurcations to the onset of chaos is considered.
Multiple-scale theory of topology-driven patterns on directed networks.
TLDR
The theory proves adequate versus simulations, as confirmed by operating with a paradigmatic reaction-diffusion model, and an effective equation for the nonlinear evolution of the amplitude of the most unstable mode, close to the threshold of criticality is derived.

Biochemical oscillations and cellular rhythms
TLDR
A model for circadian oscillations in the Drosophila period protein (PER) is proposed, which combines the periodic synthesis and relay of camp signals in Dictyostelium with the mitotic oscillator driving the cell division cycle.
