Direct measurement of the carrier leakage in an InGaAsP/InP laser [PDF]

open access: yes, 1983
Carrier leakage over the heterobarrier in an InGaAsP/InP laser is measured directly in a laser-bipolar-transistor structure.

Permanence properties of normal structure [PDF]

open access: yesPacific Journal of Mathematics, 1984
A list of equivalent conditions for a subset C of a normed space to have NS (normal structure) is given, among them, the following new characterization: C has NS iff each limit-constant sequence with convex hull in C is constant. Here, \((x_ n)\) is limit-constant (limit-affine) if the functional \(\Lambda x=\lim_{n\to \infty}\| x_ n-x\|\) is defined ...

On the structure of Normal Matrix Model

open access: yes, 1997
We study the structure of the normal matrix model (NMM). We show that all correlation functions of the model with axially symmetric potentials can be expressed in terms of holomorphic functions of one variable. This observation is used to demonstrate the

Normality and Cohen-Macaulayness of local models of Shimura varieties [PDF]

open access: yes, 2013
We prove that in the unramified case, local models of Shimura varieties with Iwahori level structure are normal and Cohen Macaulay.Comment: 13 pages, final ...

Compact leaves of codimension one holomorphic foliations on projective manifolds [PDF]

open access: yes, 2018
This article studies codimension one foliations on projective man-ifolds having a compact leaf (free of singularities). It explores the interplay between Ueda theory (order of flatness of the normal bundle) and the holo-nomy representation (dynamics of ...

Self-Dual Integral Normal Bases and Galois Module Structure

open access: yes, 2011
Let $N/F$ be an odd degree Galois extension of number fields with Galois group $G$ and rings of integers ${\mathfrak O}_N$ and ${\mathfrak O}_F=\bo$ respectively. Let $\mathcal{A}$ be the unique fractional ${\mathfrak O}_N$-ideal with square equal to the

Minimax structured normal means inference [PDF]

open access: yes2016 IEEE International Symposium on Information Theory (ISIT), 2016
We provide a unified treatment of a broad class of noisy structure recovery problems, known as structured normal means problems. In this setting, the goal is to identify, from a finite collection of Gaussian distributions with different means, the distribution that produced some observed data.
