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.

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 ...

Blow-up time and blow-up set of the solutions for semilinear heat equations with large diffusion
Advances in Differential Equations, 2002 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 ...

Lumped modeling of bubbling fluidized beds for high‐temperature processes
AIChE Journal, EarlyView.Abstract Bubbling fluidized beds (BFBs) have been a source of study for multiple decades. Among other applications, they can be used as scalable reactors for the conversion of biomass and waste resources to fuels. Several experimental and computational studies have been devoted to correlating the interplay of hydrodynamics and heat and mass transfer in

Bubbles Acting as Micro End‐Effectors for Dexterous Manipulation and Sensing in Aqueous Environment
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.Inspired by bubbles, this article proposes a low‐cost method for multifunctional manipulation and sensing using microbubbles in aqueous environments. Bubbles are easily generated in situ, enabling the safe and adaptive handling of microobjects and sensing of microforces and surface textures.

Continuity Of The Blow-Up Time For A Nonlinear Convection In Reaction-Diffusion Equation
Trends in Computational and Applied MathematicsIn 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.

A Multistage Venturi Amplifier for Rapid Inflation of Soft Robots
Advanced Intelligent Systems, EarlyView.This work presents the amplifier inflator for soft robotic systems (AIRS), a compact, lightweight, and effective device for rapidly deploying inflatable structures to high pressure. By integrating a check valve with a Venturi‐based air entrainer, AIRS delivers an initial high‐flow output followed by pressurization, supporting fast inflation and ...

Nonexistence of positive global solutions to the differential equation $u''-t^{-p-1}u^p=0$
Electronic Journal of Differential Equations, 2016 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.
