Travelling wave solutions in a negative nonlinear diffusion-reaction model. [PDF]
J Math Biol, 2020 We use a geometric approach to prove the existence of smooth travelling wave solutions of a nonlinear diffusion-reaction equation with logistic kinetics and a convex nonlinear diffusivity function which changes sign twice in our domain of interest.

Exact travelling wave solution for the local fractional Camassa-Holm-Kadomtsev-Petviashvili equation
Alexandria Engineering Journal, 2023 In this work, the local fractional Camassa-Holm-Kadomtsev–Petviashvili equation (LFCHKPE) is defined on Cantor sets by using the local fractional derivative for the first time.

Lateralization of travelling wave response in the hearing organ of bushcrickets. [PDF]
PLoS ONE, 2014 Travelling waves are the physical basis of frequency discrimination in many vertebrate and invertebrate taxa, including mammals, birds, and some insects. In bushcrickets (Tettigoniidae), the crista acustica is the hearing organ that has been shown to use

Constructing Soliton and Kink Solutions of PDE Models in Transport and Biology [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2006 We present a review of our recent works directed towards discovery of a periodic, kink-like and soliton-like travelling wave solutions within the models of transport phenomena and the mathematical biology. Analytical description of these wave patterns is

Periodic Travelling Wave Solutions of Discrete Nonlinear Schrödinger Equations
Journal of Applied Mathematics, 2017 The existence of nonzero periodic travelling wave solutions for a general discrete nonlinear Schrödinger equation (DNLS) on one-dimensional lattices is proved. The DNLS features a general nonlinear term and variable range of interactions going beyond the

Insulating traveling-wave electrophoresis
Physical Review E, 2023 Traveling-wave electrophoresis (TWE) is a method for transporting charged colloidal particles used in many microfluidic techniques for particle manipulation and fractionation. This method exploits the traveling-wave components of the electric field generated by an array of electrodes subjected to ac voltages with a phase delay between neighboring ...

A resonance approach to cochlear mechanics. [PDF]
PLoS ONE, 2012 BACKGROUND: How does the cochlea analyse sound into its component frequencies? In the 1850s Helmholtz thought it occurred by resonance, whereas a century later Békésy's work indicated a travelling wave.
