Removability conditions for anisotropic parabolic equations in a computational validation
Frontiers in Applied Mathematics and StatisticsThe article investigates removability conditions for singularities of anisotropic parabolic equations and in particular for the anisotropic porous medium equation and it aims in the numerical validation of the analytical results. The preconditions on the

Traveling fronts of pyramidal shapes in competition-diffusion systems
Networks and Heterogeneous Media, 2013 It is well known that a competition-diffusion system hasa one-dimensional traveling front.This paper studies traveling front solutions of pyramidal shapesin a competition-diffusion system in $\mathbb{R}^N$ with $N\geq 2$.By using a multi-scale method,we ...

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors
Population Ecology, EarlyView.Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Fractal and Fractional, 2022 This paper mainly considers the parameter estimation problem for several types of differential equations controlled by linear operators, which may be partial differential, integro-differential and fractional order operators. Under the idea of data-driven

Population Ecology, EarlyView.Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size
