THE MINIMAL SPEED OF TRAVELING WAVE SOLUTIONS FOR A DIFFUSIVE THREE SPECIES COMPETITION SYSTEM

open access: yesTaiwanese Journal of Mathematics, 2015
In this paper, we study the minimal speed of traveling wave solutions for a diffusive three species competition system. Our main concern is the linear determinacy for the minimal speed. We provide some conditions on the parameters of the competition system such that the linear determinacy is assured.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

open access: yesAdvanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Traveling wave solutions of nonlocal delay reaction-diffusion equations without local quasimonotonicity

open access: yesElectronic Journal of Differential Equations, 2014
This article concerns the traveling wave solutions of nonlocal delay reaction-diffusion equations without local quasimonotonicity. The existence of traveling wave solutions is obtained by constructing upper-lower solutions and passing to a limit ...

Existence and asymptotics of traveling wave fronts for a coupled nonlocal diffusion and difference system with delay

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
In this paper, we consider a general study of a recent proposed hematopoietic stem cells model. This model is a combination of nonlocal diffusion equation and difference equation with delay.

Master-modes in 3D turbulent channel flow [PDF]

open access: yes, 2008
Turbulent flow fields can be expanded into a series in a set of basic functions. The terms of such series are often called modes. A master- (or determining) mode set is a subset of these modes, the time history of which uniquely determines the time ...

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

open access: yesAdvanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Qualitative properties of traveling wavefronts for a three-component lattice dynamical system with delay

open access: yesElectronic Journal of Differential Equations, 2019
This article concerns a three-component delayed lattice dynamical system arising in competition models. In such models, traveling wave solutions serve an important tool to understand the competition mechanism, i.e.

A new estimate on the minimal wave speed for travelling fronts in reaction–diffusion–convection equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
In this paper we prove a new estimate of the threshold wave speed for traveling wavefronts of the reaction–diffusion–convection equations of the type \[v_\tau + h(v) v_x= \left[ D(v)v_x \right]_x + f(v) \] where \(h\) is a convective term, \(D\) is a ...
