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
