Near-field optical spectroscopy is used to investigate the effects of disorder in the optical processes in semiconductor quantum wires. We observe photoluminescence emissions from extended, delocalized excitons at low temperatures (5 K) and low excitation ...
The traffic generated by multimedia applications presents a high degree of burstiness that can be hardly described by a static set of traffic parameters. The following paper presents a dynamic QoS negotiation scheme applied to a video streaming application ...
Gallium impurities affect the atomic processes and material properties of aluminum metal to a high degree. Various ab initio calculations have been performed on a Sigma = 11 (113) symmetric tilt boundary in aluminum with and without some gallium substituti ...
Sugar-beet pulp was saponified and then hydrolysed with 0.1 M HCl at 80 degrees C for 72 h, and a rhamnogalacturonan fraction was isolated by ion-exchange chromatography on AG 1X8 resin. Four individual oligomers, and a mixture of oligomers with higher deg ...

We study the ultrafast dynamics of structural relaxation induced by the Rydberg excitation of an NO molecule in an Ar crystal. We used classical molecular dynamics simulations and normal mode analysis to describe the dynamics of the cage of Ar atoms surrou ...
In recent decades, East and South-East Asia have became both politically and economically significant for the West and it is no longer possible to ignore the history and culture of this large portion of the world's population. Advanced studies on the vario ...
John Wilder Tukey, Donner Professor of Science Emeritus at Princeton University, was born in New Bedford, Massachusetts, on June 16, 1915. After earning bachelor's and master's degrees in chemistry at Brown University in 1936 and 1937, respectively, he sta ...
We investigate the functions of given approximation order L that have the smallest support. Those are shown to be linear combinations of the B-spline of degree L-1 and its L-1 first derivatives. We then show how to find the functions that minimize the asym ...
