Blow-Up Solutions and Global Solutions to Discrete p-Laplacian Parabolic Equations
Abstract and Applied Analysis, 2014 We discuss the conditions under which blow-up occurs for the solutions of discrete p-Laplacian parabolic equations on networks S with boundary ∂S as follows: ut(x,t)=Δp,ωu(x,t)+λ|u(x,t)|q-1u(x,t), (x,t)∈S×(0,+∞); u(x,t)=0, (x,t)∈∂S×(0,+∞); u(x,0)=u0≥0, x∈

Advanced Science, EarlyView.Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.

Blow-up for a semilinear heat equation with moving nonlinear reaction
Electronic Journal of Differential Equations, 2018 We study the behavior of solutions of the semilinear problem $$\displaylines{ u_t=u_{xx}+(1+(T-t)^{-\alpha}\chi_{\{|x|0$ and p>0 We describe, in terms of the parameters when the solution is bounded and when it blows up.

Blow-up rate estimates for a doubly coupled reaction–diffusion system
Journal of Mathematical Analysis and Applications, 2005 The authors consider a reaction-diffusion system, where the equations are coupled via nonlinear sources and a nonlinear boundary flux. Blow-up rates under different conditions are determined. The so-called characteristic algebraic system has been introduced in order to get a brief description for the blow-up rate estimates.

Hydrogen Production from Ammonia Electrochemical Cracking
Advanced Science, EarlyView.NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Advanced Science, EarlyView.A subset of tumor‐associated macrophages (TAMs) characterized by SPP1 expression is discovered, which may remodel the tumor microenvironment by potentially promoting CD4+ T cell stress and maintaining epithelial cell stemness through SPP1‐CD44, thereby potentially contributing to the proliferation and migration of tumor cells, which has been verified ...
