Blow-up problem for semilinear heat equation with nonlinear nonlocal Neumann boundary condition [PDF]
, 2016 In this paper, we consider a semilinear parabolic equation with nonlinear nonlocal Neumann boundary condition and nonnegative initial datum. We first prove global existence result.

A Neumann Boundary Term for Gravity
, 2017 The Gibbons-Hawking-York (GHY) boundary term makes the Dirichlet problem for gravity well defined, but no such general term seems to be known for Neumann boundary conditions. In this paper, we view Neumann {\em not} as fixing the normal derivative of the

Blow-up problems for the heat equation with a local nonlinear Neumann boundary condition [PDF]
, 2015 This paper estimates the blow-up time for the heat equation u t = Δ u with a local nonlinear Neumann boundary condition: The normal derivative ∂ u / ∂ n = u q on Γ 1 , one piece of the boundary, while on the rest part of the boundary, ∂ u / ∂ n = 0 . The

Isospectral shapes with Neumann and alternating boundary conditions [PDF]
Physical Review E, 2003 The isospectrality of a well-known pair of shapes constructed from two arrangements of seven congruent right isosceles triangles with the Neumann boundary condition is verified numerically to high precision. Equally strong numerical evidence for isospectrality is presented for the eigenvalues of this standard pair in new boundary configurations with ...

Boundary unique continuation theorems under zero Neumann boundary conditions [PDF]
Bulletin of the Australian Mathematical Society, 2005 Let u be a solution to a second order elliptic equation with singular potentials belonging to the Kato-Fefferman-Phong's class in Lipschitz domains. We prove the boundary unique continuation theorems and the doubling properties for u2 near the boundary under the zero Neumann boundary condition.

On the Solvability of Discrete Nonlinear Two-Point Boundary Value Problems
International Journal of Mathematics and Mathematical Sciences, 2012 We prove the existence and uniqueness of solutions for a family of discrete boundary value problems by using discrete's Wirtinger inequality. The boundary condition is a combination of Dirichlet and Neumann boundary conditions.

A trifurcated waveguide problem II [PDF]
, 1994 We consider the diffraction of the dominant plane wave mode which propagates out of the end of a semi-infinite waveguide. This waveguide is made up of a half plane with a Dirichlet boundary condition and a half plane with a Neumann boundary condition ...

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
