NettetIn contrast to other known spiral chimeras with motionless incoherent cores, the two-core spiral chimeras typically show a drift motion. Due to this drift, their incoherent cores … NettetIt is firstly shown that this discrete-time neural network can exhibit spiral and target waves and corresponding chimera states when the control parameters (the coupling stren … Spiral and target wave chimeras in a 2D lattice of map-based neuron models Chaos. 2024 Oct;29(10):101104. doi: 10.1063/1.5126178. ...

Nettet21. jan. 2024 · We study traveling wave solutions relevant to traveling chimera states in the coupled oscillator system. In particular, we derive and rigorously justify asymptotic formulas for traveling wave... Nettet1. aug. 2024 · The spiral wave chimeras are extended to appear also in the paradigmatic Stuart–Landau system of amplitude–phase oscillators with space-dependent delays, for which the chimeric patterns appear not only in the phase but simultaneously in phase and amplitude. 2.

NettetThe paper describes the effects of mutual and external synchronization of spiral wave structures in two coupled two-dimensional lattices of coupled discrete-time oscillators. Each lattice is given by a 2D N×N network of nonlocally coupled Nekorkin maps which model neuronal activity. We show numerica … Nettetscroll wave chimeras and the impact of inertia on scroll wave chimeras in a system without inertia are analyzed. We demonstrate that the 3D scroll wave chimeras can be surrounded by solitary oscillators [25, 26] (like a \soli-tary cloud") (Fig. 1 (c)). In [27], the spiral wave chimeras with solitary clouds have been studied in the case of the Nettet5. okt. 2024 · Therefore, many feasible schemes have also been presented to suppress spiral waves and turbulence, where they can be eliminated by local periodic perturbation [ 40, 41, 42 ], moving localized inhomogeneous obstacle [ 20 ], a rotating electric field [ 43, 44 ], external periodic forcing [ 45 ], weak spatial wave [ 46 ], chaotic signals [ 47 ], … top shelf memphis tn
