Invasion entire solutions in a competitionsystem with nonlocal dispersal

Discrete and Continuous Dynamical Systems, 2015
Consider the following Lotka-Volterra competition system with nonlocal dispersal \[ \begin{cases} {\partial u(x,t)\over \partial t}=J_1*u(x,t)-u(x,t)+u(x,t)(1-u(x,t)-a_1v(x,t)), \\ {\partial v(x,t)\over \partial t}=d(J_1*u(x,t)-u(x,t))+rv(x,t)(1-v(x,t)-a_2u(x,t)), \end{cases} \] where \((x,t)\in \mathbb{R}\times \mathbb{R}\) and \(d,r,a_1,a_2\) are ...

Minimal wave speeds of delayed dispersal predator-prey systems with stage structure

Electronic Journal of Differential Equations, 2016
This article concerns the minimal wave speed of delayed predator-prey systems with nonlocal dispersal and stage structure. By the method of upper and lower solutions, we prove the existence of positive traveling wave solutions.

Two centuries of human‐mediated gene flow in northern bobwhites

Wildlife Society Bulletin, 2017
The northern bobwhite (Colinus virginianus; hereafter, bobwhite) population decline has prompted several studies over the past decade investigating bobwhite population genetics and overall connectivity. The zeitgeist of current quail conservation is that

Traveling wave solutions of a nonlocal dispersal SIRS model with spatio-temporal delay

, 2017
This paper is mainly concerned with the existence and nonexistence of traveling wave solutions of a nonlocal dispersal SIRS model with nonlocal delayed transmissions. We find that the existence and nonexistence of traveling wave solutions are determined

Is a nonlocal diffusion strategy convenient for biological populations in competition? [PDF]

, 2015
We study the viability of a nonlocal dispersal strategy in a reaction-diffusion system with a fractional Laplacian operator. We show that there are circumstances—namely, a precise condition on the distribution of the resource—under which the introduction

Pseudomagnetic fields for classical waves in two‐dimensional artificial lattices: Mechanisms and applications

InfoScience, EarlyView.
Pseudomagnetic fields make light and sound emulate charged particles in magnetic fields, enabling magnetic‐free signal processing. This Review summarizes their origins, three implementations in two‐dimensional artificial lattices, and applications in energy localization and robust transport, guiding the design of topological integrated devices ...

Quantization of Polaritons Confined in Dielectric Structures

Laser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Existence of forced waves and gap formations for a Lotka-Volterra competition system with nonlocal dispersal in a time periodic shift habitat

Mathematics in Applied Sciences and Engineering
This paper is devoted to the study of a class of time periodic Lotka-Volterra competition system with nonlocal dispersal and shifting habitats. By using some known results of the periodic KPP model and employing the iterative techniques, we prove that ...

Metasurface‐Enabled Single‐Shot Intensity‐and‐Phase‐Interrogation Surface‐Plasmon‐Resonance Microscopy

Laser &Photonics Reviews, EarlyView.
A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...
