“…In the study of temporal dynamics of many dynamical systems, the occurrence of infrequent but recurrent comparatively high or low amplitude events might have qualitative similarities with occasional large events being recorded in many real-world phenomena. The emergence of EEs is reported in several dynamical systems such as FitzHugh-Nagumo oscillators, 29,[31][32][33][34][35] Hindmarsh-Rose model, 36 Liénard system, 37 Ikeda map, 25 Josephson junctions, 38 Ginzburg-Landau model, 39 nonlinear Schrödinger equation, 40 micromechanical system, 41 climatic models, 42 ecological model, 43 mechanical system, 44 and electronic circuits, 45 to name but a few. In addition, we also find some experimental evidence of the appearance of EEs, such as in laser systems, 46 epileptic EEG studies in rodents, 47 annular wave flume, 48 and laser systems, 49 to name but a few.…”
