Dynamics in diffusive Leslie–Gower prey–predator model with weak diffusion

open access: yesNonlinear Analysis, 2022
This paper is concerned with the diffusive Leslie–Gower prey–predator model with weak diffusion. Assuming that the diffusion rates of prey and predator are sufficiently small and the natural growth rate of prey is much greater than that of predators ...

Relaxation Oscillations and Dynamical Properties in Two Time-Delay Slow-Fast Modified Leslie-Gower Models

open access: yesComplexity, 2020
In this paper, we consider two kinds of time-delay slow-fast modified Leslie-Gower models. For the first system, we prove the existence and uniqueness of relaxation oscillation cycle through the geometric singular perturbation theory and entry-exit ...

Real-Time Exploration on Buildup Dynamics of Diode-Pumped Passively Mode-Locked Nd:YVO4 Laser with SESAM

open access: yesPhotonics, 2023
The buildup dynamics of diode-pumped passively mode-locked solid-state laser is thoroughly explored using the real-time measurement with temporal sampling rate of up to 40 GHz. A concise cavity is developed to ensure the transient dynamics purely arising

Relative entropy in diffusive relaxation [PDF]

open access: yes, 2012
We establish convergence in the diffusive limit from entropy weak solutions of the equations of compressible gas dynamics with friction to the porous media equation away from vacuum.

Temperature dependence of relaxation spectra for highly hydrated gluten networks [PDF]

open access: yes, 2010
In the present investigation, the temperature dependence (0e50 C) of the relaxation spectrum of hydrated gluten was studied using novel numerical algorithms. Tikhonov regularization, in conjunction with the L-curve criterion for optimal calculation of

Psi-Hilfer fractional relaxation-oscillation equation [PDF]

open access: yes, 2022
In this work, we solve the ψ-Hilfer fractional relaxation-oscillation equation with a force term, where the time-fractional derivatives are in the ψ-Hilfer sense. The solution of the equation is presented in terms of bivariate Mittag-Leffler functions.

Relaxation oscillation dynamics in semiconductor diode lasers with optical feedback [PDF]

open access: yes, 2013
We theoretically investigate the stability of a single-mode semiconductor laser with weak optical feedback in the short external-delay regime. Although the laser is, in general, very sensitive to feedback-induced excitation of relaxation oscillations, we

Phase Equations for Relaxation Oscillators [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2000
Summary: We use the Malkin theorem [see \textit{I. G. Malkin}, Some problems in nonliner oscillations theory. (Russian) (1956; Zbl 0070.08703)] to derive phase equations for networks of weakly connected relaxation oscillators. We find an explicit formula for the connection functions when the oscillators have one-dimensional slow variables.

Noise in (double) relaxation oscillation SQUIDs [PDF]

open access: yes, 1994
We have modelled the effect of two intrinsic noise sources on the flux noise spectral density of (Double) Relaxation Oscillation SQUIDs ((D)ROSs) based on hysteretic Josephson tunnel junctions.
