Identify hidden spreaders of pandemic over contact tracing networks
Scientific Reports, 2023 The COVID-19 infection cases have surged globally, causing devastations to both the society and economy. A key factor contributing to the sustained spreading is the presence of a large number of asymptomatic or hidden spreaders, who mix among the ...

On a Multistable Type of Free Boundary Problem with a Flux at the Boundary
Advances in Mathematical Physics, 2023 This paper studies the free boundary problem of a multistable equation with a Robin boundary condition, which may be used to describe the spreading of the invasive species with the solution representing the density of species and the free boundary ...

Spreading Speed in A Nonmonotone Equation with Dispersal and Delay
Mathematics, 2019 This paper is concerned with the estimation of spreading speed of a nonmonotone equation, which involves time delay and nonlocal dispersal. Due to the time delay, this equation does not generate monotone semiflows when the positive initial value is given.

Asymptotic behaviors for nonlocal diffusion equations about the dispersal spread [PDF]
Analysis and Applications, 2020 This paper studies the effects of the dispersal spread, which characterizes the dispersal range, on nonlocal diffusion equations with the nonlocal dispersal operator [Formula: see text] and Neumann boundary condition in the spatial heterogeneity environment.

Asymptotic states for kink–meson scattering
European Physical Journal C: Particles and Fields, 2023 The definition of a quantum state corresponding to a wave packet far from a global soliton is considered. We define an asymptotic quantum state corresponding to a localized wave packet of elementary quanta far from a kink.

Asymptotic behavior of solutions of a Fisher equation with free boundaries and nonlocal term
Electronic Journal of Qualitative Theory of Differential Equations, 2019 We study the asymptotic behavior of solutions of a Fisher equation with free boundaries and the nonlocal term (an integral convolution in space). This problem can model the spreading of a biological or chemical species, where free boundaries represent ...

Exact hydrodynamic solution of a double domain wall melting in the spin-1/2 XXZ model
SciPost Physics, 2022 We investigate the non-equilibrium dynamics of a one-dimensional spin-1/2 XXZ model at zero-temperature in the regime $|\Delta|< 1$, initially prepared in a product state with two domain walls i.e, $|\downarrow\dots\downarrow\uparrow\dots\uparrow ...
