Schwann cell remyelination of the central nervous system
Myelin sheaths, by supporting axonal integrity and allowing rapid saltatory impulse conduction, are of fundamental importance for neuronal function. In response to demyelinating injuries in the central nervous system (CNS)...
Norm-resolvent convergence for Neumann Laplacians on manifolds thinning to graphs
Norm-resolvent convergence with an order-sharp error estimate is established for Neumann Laplacians on thin domains in ℝ, ≥2, converging to metric graphs in the limit of vanishing thickness parameter in the “resonant” case. The...

Interior Regularity Estimates for a Degenerate Elliptic Equation with Mixed Boundary Conditions
The Marchaud fractional derivative can be obtained as a Dirichlet-to–Neumann map via an extension problem to the upper half space. In this paper we prove interior Schauder regularity estimates for a degenerate elliptic...
Sharp high-frequency estimates for the Helmholtz equation and applications to boundary integral equations
We consider three problems for the Helmholtz equation in interior and
exterior domains in R^d, (d = 2, 3): the exterior Dirichlet-to-Neumann and Neumann-to-Dirichlet problems for outgoing solutions, and the interior...

Achieving Conformance to Document Standards
In the context of long-term archival of digital assets, file formats that are standardized and designed for longevity such as PDF/A are preferred. However, due to the complexity of and ambiguities in PDF standards, it is far...

An Iterative Rejection Sampling Method
A Sherstnev
Jan 19, 2010
In the note we consider an iterative generalisation of the rejection sampling
method. In high energy physics, this sampling is frequently used for event
generation, i.e. preparation of phase space points distributed according to...
Wavenumber-Explicit Bounds in Time-Harmonic Acoustic Scattering
We prove wavenumber-explicit bounds on the Dirichlet-to-Neumann map for the Helmholtz equation in the exterior of a bounded obstacle when one of the following three conditions holds: (i) the exterior of the obstacle is...

A 'divide and choose' approach to compromising
Peter Postl
Jan 01, 0001
We study dispute resolution in the compromise model of Borgers and Postl (2009), which provides an alternative framework for analyzing the real-world procedure of tri-offer arbitration studied in Ashenfelter et al (1992). Two...
