Non-Classical Relaxation Oscillations in Neurodynamics
Моделирование и анализ информационных систем, 2014 A modification of the well-known FitzHugh–Nagumo model from neuroscience is proposed. This model is a singularly perturbed system of ordinary differential equations with a fast variable and a slow one.

Pleasant odors specifically promote a soothing autonomic response and brain–body coupling through respiratory modulation [PDF]
Scientific ReportsNeuronal oscillations are tightly linked to physiological rhythms, yet little is known about how sensory stimuli influence their coupling. Here, we investigated whether pleasant odors and pleasant music modulate the coupling between respiration ...

Relaxation oscillations in energy active zones [PDF]
E3S Web of Conferences, 2020 Relaxation oscillations in energy active natural zones are considered as causes of sudden catastrophes. A general approach to the study of dynamical systems of a fast-slow type is proposed, the relaxation oscillations of which give an adequate ...

Understanding Relaxation Oscillator Circuits Using Fast-Slow System Representations
IEEE Access, 2023 We demonstrate the utilization of the fundamental principle of nonlinear dynamics, namely, the Liénard-type representations of ordinary differential equations, also referred to as fast-slow systems, to describe and understand relaxation ...

Influence of coupling on the dynamics of three delayed oscillators [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2021 The purpose of this study is to construct the asymptotics of the relaxation regimes of a system of differential equations with delay, which simulates three diffusion-coupled oscillators with nonlinear compactly supported delayed feedback under the ...

Two-stroke relaxation oscillators [PDF]
Nonlinearity, 2020 Two-stroke relaxation oscillations consist of two distinct phases per cycle - one slow and one fast - which distinguishes them from the well-known van der Pol-type 'four-stroke' relaxation oscillations. This type of oscillation can be found in singular perturbation problems in non-standard form, where the slow-fast timescale splitting is not ...

Excitation and control of spin waves in FeBO3 by a strong-field THz pulse [PDF]
EPJ Web of Conferences, 2019 The dynamically resolved response of the canted-antiferromagnet FeBO3 excited near a magnon resonance shows fast oscillations after THz-excitation’ followed by the magnons’ intrinsic relaxation’ enabling to probe transient magnetic relaxation dynamics ...

Travelling Waves in the Ring of Coupled Oscillators with Delayed Feedback
Mathematics, 2023 We studied travelling waves in N nonlinear differential equations with a delay and large parameter. This system is important because it can be regarded as a phenomenological model of N-coupled neuron-like oscillators with delay.

Lateral vibration control of a beam subjected to the harmonic external load using a nonlinear energy sink [PDF]
مجله مدل سازی در مهندسی, 2018 Annihilating of unwanted vibrations of mechanical systems is one of the necessary requirements of designers over years. This current paper investigates dynamical behavior of a clamped-clamped beam attached to a Nonlinear Energy Sink (NES) under the ...
