Room temperature electron mobility of 1170 cm(2)/V s is obtained in an undoped, lattice-matched, Al0.82In0.18N/GaN field-effect transistor heterostructure, while keeping a high (2.6 +/- 0.3)x10(13) cm(-2) electron gas density intrinsic to the Al0.82In0.18N ...
A link to a wide range of spatio-temporal practices, mobility is nowadays an important factor of social relations. If the spatio-temporal practices and mobility forms are not homogenous, how can we, however, describe them, qualify and make them more compre ...

"Architecturaliser" the suburb is the study of contemporary urban forms of development that have emerged due to the rise of individual mobility and the manner in which people shop. This work investigates shopping centers, in terms of their physical structu ...
We study private computations in a system of tiny mobile agents. We consider the mobile population protocol model of Angluin et al. [2] and ask what can be computed without ever revealing any input to a curious adversary. We show that any computable predic ...
Lindane, the gamma-isomer of hexachlorocyclohexane (HCH), is a potent insecticide. Purified lindane or unpurified mixtures of this and alpha-, beta-, and gamma- isomers of HCH were widely used as commercial insecticides in the last half of the 20th century ...
The Zambezi Basin, a semi-arid 1.4 Mio km2 catchment area spreading across eight countries, constitutes a highly complex system. With several large dams, namely Kariba, Cahora Bassa, Kafue Gorge and Itezhi-Tezhi, the basin’s hydrology is also influenced by ...
We describe our design of a geocast service for mobile partitioned networks (MPNs). We focus mainly on minimizing the delivery latency. Our approach exploits the time-stability of the collective mobility pattern. In MPNs, in contrast to MANETs, the end-to- ...
Job-related spatial mobility is a subject of great importance in Europe. But how mobile are the Europeans? What are the consequences of professional mobility for quality of life, family life and social relationships? For the first time these questions are ...
Mobile wireless networks frequently possess, at the same time, both dense and sparse regions of connectivity; for example, due to a heterogeneous node distribution or radio propagation environment. This paper is about modeling both the mobility and the for ...
