Optical identification of ISO far-infrared sources in the Lockman Hole using a deep VLA 1.4 GHz continuum survey [PDF]

, 2005
By exploiting the far-infrared(FIR) and radio correlation, we have performed the Likelihood-Ratio analysis to identify optical counterparts to the far-infrared sources in the Lockman Hole.

Crystal structure and charge distribution of pyrazine: effects of extinction, thermal diffuse scattering and series termination [PDF]

, 1976
The crystal structure and electronic charge distribution of pyrazine (1,4-diazabenzene) has been determined at 184 K by X-ray methods. The structural results of Wheatley [Acta Cryst. (1957), 10, 182-187] have been confirmed. A clear indication of bonding

The Cosmic Horseshoe: Discovery of an Einstein Ring around a Giant Luminous Red Galaxy [PDF]

, 2007
We report the discovery of an almost complete Einstein ring of diameter 10" in Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5). Spectroscopic data from the 6m telescope of the Special Astrophysical Observatory reveals that the deflecting galaxy has ...

Transformation elastodynamics and active exterior acoustic cloaking

, 2011
This chapter consists of three parts. In the first part we recall the elastodynamic equations under coordinate transformations. The idea is to use coordinate transformations to manipulate waves propagating in an elastic material. Then we study the effect

Immersed boundary method predictions of shear stresses for different flow topologies occuring in cerebral aneurysms [PDF]

, 2010
A volume-penalizing immersed boundary method is presented that facilitates the computation of incompressible fluid flow in complex flow domains. We apply this method to simulate the flow in cerebral aneurysms, and focus on the accuracy with which the ...
