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 ...

Electronic Journal of Differential Equations, 2014 In this article, we study the $\omega$-diffusion equation on a graph with Dirichlet boundary conditions $$\displaylines{ u_t(x,t)=\Delta_{\omega}u(x,t)+e^{\beta t}u^{p}(x,t), \quad (x,t)\in S\times(0,\infty), \cr u(x,t)=0, \quad (x,t)\in \partial S ...

Adaptive Cellular Responsiveness to Electrical Stimulation at the Skin‐Electrode Interface
Advanced Science, EarlyView.This study presents an adaptive bioelectronic response in which sustained electrical stimulation (ES) upregulates voltage‐gated calcium channels (VGCCs) and enhances cellular sensitivity to subsequent ES at the skin‐device interface. VGCC‐associated adaptive sensitization promotes regenerative wound‐healing responses in vivo, including accelerated ...

Numerical approximations for blow-up problems [PDF]
, 2003 Estudiamos el comportamiento asintótico de aproximaciones numéricas para problemas con blow-up. Probamos que al aproximar este tipo de problemas muchas veces los métodos usuales reproducen el comportamiento asintótico de la solución continua, sin embargo

Blow-up in reaction-diffusion equations with exponential and power-type nonlinearities [PDF]
, 2011 In this dissertation we study blow-up phenomena in semilinear parabolic equations with both exponential and power-type nonlinearities. We study the behavior of the solutions as the blow-up moment in time and the blow-up point in space are approached ...

Advanced Electronic Materials, EarlyView.Organic permeable base transistors are shown to benefit from balanced control of the semiconductor layers above and below the permeable base. Simulations and experiments indicate that the top semiconductor layer affects charge injection and lateral transfer length, while the bottom layer modulates the collector‐induced short‐channel effects.

Blow-up of positive solutions of a semilinear parabolic equation with a gradient term
, 2003 We study the blow-up behavior (in time and space) of positive solutions of a semilinear parabolic equation with a gradient term. Our main result is a sharp estimate for the spatial blow-up profile of radially decreasing solutions on a ball.

Agribusiness, EarlyView.ABSTRACT In emerging economies where smallholder farming dominates agricultural production, agribusinesses serve as critical intermediaries linking smallholders to broader markets, and their resilience directly affects agricultural sustainability. Short‐term‐oriented capital is reluctant to adequately finance highly uncertain and cyclical agricultural ...
