Bose-Einstein Correlations from Opaque Sources
, 1997 Bose-Einstein correlations in relativistic heavy ion collisions are very different for opaque sources than fortransparent ones. The Bose-Einstein radius parameters measured in two-particle correlation functions depend sensitively on the mean free path of

Advanced Engineering Materials, EarlyView.This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.

Déformation de Madelung à propos d�un cas et revue de la littérature
The Pan African Medical Journal, 2016 La maladie de Madelung est une déformation du poignet due à une atrophie de la partie médiale du cartilage de croissance distal du radius. Il en résulte une subluxation antéro-médiale du carpe,limitant les amplitudes articulaires. Cette dysplasie osseuse

Advanced Engineering Materials, EarlyView.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

GIANT CELL TUMOR OF THE LOWER END OF THE RADIUS
Acta Medica Iranica, 1999 Five cases of giant cell tumor of the lower end of radius are reported. Three of the patients were women and two were men, the youngest of the patients was 18 years old and oldest 37 years.

Advanced Engineering Materials, EarlyView.This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,

The decomposable numerical radius and numerical radius of a compound matrix
Linear Algebra and its Applications, 1986 AbstractLet A be an n × n complex matrix with singular values α1 ⩾ α2 ⩾ ⋯ ⩾ αn and eigenvalues λ1, λ2,…,λn, where |λ1| ⩾ |λ2| ⩾ ⋯ ⩾ |λn|. Denote by Cm (A) (1 ⩽ m ⩽ n) the mth compound of A, and by ⋀mCn the mth Grassmann space over Cn, in which the elements are regarded as complex row vectors with nm coordinates.
