Monotone iteration scheme and its application to partial differential equation systems with mixed nonlocal and degenerate diffusions

Electronic Journal of Differential Equations, 2019
A monotone iteration scheme for traveling waves based on ordered upper and lower solutions is derived for a class of nonlocal dispersal system with delay.

Nonlocal anisotropic dispersal with monostable nonlinearity

Journal of Differential Equations, 2008
We study the travelling wave problem J\astu - u - cu' + f (u) = 0 in R, u(-\infty) = 0, u(+\infty) = 1 with an asymmetric kernel J and a monostable nonlinearity. We prove the existence of a minimal speed, and under certain hypothesis the uniqueness of the profile for c = 0. For c = 0 we show examples of nonuniqueness.

A nonlocal eigenvalue problem and the stability of spikes for reaction-diffusion systems with fractional reaction rates [PDF]

, 2003
We consider a nonlocal eigenvalue problem which arises in the study of stability of spike solutions for reaction-diffusion systems with fractional reaction rates such as the Sel'kov model, the Gray-Scott system, the hypercycle Eigen and Schuster ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

High Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Propagation of calcium waves in a bistable buffered system with nonlocal dispersal

Advanced Nonlinear Studies
We investigate wave propagation in a bistable buffered system with nonlocal dispersal. A central question in this problem is the effect of stationary buffers on calcium waves.

Do the accessibility and guardianship characteristics of places matter? Exploring population presence and crime relationships using urban digital traces

Criminology &Public Policy, EarlyView.
Abstract Research Summary Ron Clarke argued that crime prevention must be tailored to the specific situations in which crime occurs. Central to this principle are the characteristics of places: the access, responsibility, and guardianship features of a place shape who is present, for what purpose, and under whose supervision and, therefore, whether ...

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale

Nonlocal problems in Hilbert spaces [PDF]

, 2015
An existence result for differential inclusions in a separable Hilbert space is furnished. A wide family of nonlocal boundary value problems is treated, including periodic, anti-periodic, mean value and multipoint conditions.
