Continuity Of The Blow-Up Time For A Nonlinear Convection In Reaction-Diffusion Equation
In this paper, we consider a nonlinear convection reaction diffusion equation. Under some assumptions, we show that the solution of the problem blows up in a finite time and we estimate its blow-up time.

Blow-up time and blow-up set of the solutions for semilinear heat equations with large diffusion
Of concern is the blow-up of positive solutions to the Cauchy-Neumann problem \(u_t= d\Delta u+u^p\) on a cylindrical domain \(D= D_1\times (0,L)\subset \mathbb{R}^n\) accompanied with positive initial data \(\varphi\in C(\overline{D})\). Here \(p>1\) is fixed, the diffusion constant \(d>0\) is a parameter and the solutions are denoted as \(u_d\) in ...

Blowing up at zero points of potential for an initial boundary value problem
We study nonnegative radially symmetric solutions for a semilinear heat equation in a ball with spatially dependent coefficient which vanishes at the origin. Our aim is to construct a solution that blows up at the origin where there is no reaction.

Atomistic Kinetics of Dislocation‐Mediated Grain Growth in Monolayer MoS2
Atomic‐resolution in‐situ heating microscopy directly visualizes dislocation‐mediated grain boundary migration and grain growth in monolayer MoS2. Mobile grain boundaries migrate through collective motion of Mo 5|7 dislocations, whereas S 5|7 defects remain largely immobile.

Nonexistence of positive global solutions to the differential equation $u''-t^{-p-1}u^p=0$
In this article we consider the ordinary differential equation $$ u'' -t^{-p-1} u^p =0. $$ We show the blow-up for solutions of this equation, under certain on the initial data.

Integrability of blow-up solutions to some non-linear differential equations
We investigate the integrability of solutions to the boundary blow-up problem $$ r^{-lambda}(r^{lambda}(u')^{p-1})'=H(r,u),quad u'(0)geq 0,quad u(R)=infty $$ under some appropriate conditions on the non-linearity $H$.

Estimates of blow-up time for a non-local problem modelling an Ohmic heating process
We consider an initial boundary value problem for the non-local equation, ut = uxx+λf(u)/(∫1-1f (u)dx)2, with Robin boundary conditions. It is known that there exists a critical value of the parameter λ, say λ*, such that for λ > λ* there is no ...
