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 ...

A mixed method for Dirichlet problems with radial basis functions
, 2013 We present a simple discretization by radial basis functions for the Poisson equation with Dirichlet boundary condition. A Lagrangian multiplier using piecewise polynomials is used to accommodate the boundary condition.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation
Advanced Functional Materials, EarlyView.A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

Experimental Observation of a Calcium Silicon Double Carbonate
Angewandte Chemie, EarlyView.High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

A strongly ill-posed integro-differential parabolic problem with integral boundary conditions
Mathematical Modelling and Analysis, 2013 Via Carleman estimates we prove uniqueness and continuous dependence results for an identification and strongly ill-posed linear integro-differential parabolic problem with the Dirichlet boundary condition, but with no initial condition.

Asymptotic behavior of a fourth order mean field equation with Dirichlet boundary condition [PDF]
, 2007 We consider asymptotic behavior of the following fourth order equation ∇ 2 u = ρ e u /∫ Ω e u d x in Ω, u= δvU = 0 on δΩ Δ 2 u = ρ e u /∫ Ω e u dx in Ω, u = δ v u = 0 On δΩ where Q is a smooth oriented bounded domain in Ρ 4 .

Second order PDEs with Dirichlet white noise boundary conditions [PDF]
Journal of Evolution Equations, 2014 In this paper we study the Poisson and heat equations on bounded and unbounded domains with smooth boundary with random Dirichlet boundary conditions. The main novelty of this work is a convenient framework for the analysis of such equations excited by the white in time and/or space noise on the boundary.

A Bioresorbable Neural Interface for On‐Demand Thermal Pain Block
Advanced Functional Materials, EarlyView.Bioresorbable, implantable neural electronics provide dynamic, on‐demand thermal modulation of peripheral nerves for safe, drug‐free pain relief. A microscale thin‐film heater and temperature sensor embedded within biodegradable encapsulants enable precise temperature control via real‐time feedback.
