Existence result for a nonlocal viscous Cahn-Hillard equation with a degenerate mobility [PDF]
We study a diffusion model of phase field type, consisting of a system of two partial differential equations of second order for the particle densities and the viscosity variable, coupled by a nonlocal drift term.

A nonlocal sinusoidal shear deformation beam theory with application to bending, buckling, and vibration of nanobeams [PDF]
This paper presents a nonlocal sinusoidal shear deformation beam theory for the bending, buckling, and vibration of nanobeams. The present model is capable of capturing both small scale effect and transverse shear deformation effects of nanobeams, and ...

Spreading speeds for monostable equations with nonlocal dispersal in space periodic habitats [PDF]
. The current paper is devoted to the study of spatial spreading dynamics of monostable equations with nonlocal dispersal in spatially periodic habitats. In particular, the existence and characterization of spreading speeds is considered.

Spatial propagation in nonlocal dispersal Fisher-KPP equations
In this paper we focus on three problems about the spreading speeds of nonlocal dispersal Fisher-KPP equations. First, we study the signs of spreading speeds and find that they are determined by the asymmetry level of the nonlocal dispersal and f′(0 ...

Global dynamics of population-toxicant models with nonlocal dispersals
In the article, we first investigate a population-toxicant model with nonlocal dispersal. Compared to the local dispersal (random dispersal), nonlocal dispersal brings some difficulties.

Nonlocal Dispersal Equations and Convergence to Random Dispersal Equations [PDF]
This dissertation is devoted to the study of the dynamics of nonlocal and random dispersal evolution equations. Dispersal evolution equations are widely used to model the diffusions of organisms or individuals in many biological and ecological systems.

The spreading speed of an SIR epidemic model with nonlocal dispersal
In this paper, we study an SIR epidemic model with nonlocal dispersal. We study the case with vital dynamics so that a renewal of the susceptible individuals is taken into account.

Plasmon‐Enhanced Second‐Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures
Atomically thin crystalline silver films combine vertical quantum confinement with lateral plasmonic field enhancement to boost second‐harmonic generation. Nanoribbon and nanotriangle arrays enable geometry‐tunable infrared plasmon resonances, producing strong SHG from deeply subwavelength metallic volumes compatible with silicon‐based nanophotonics ...
