We present the results of a plane wave based density functional study of the structure and properties of tetragonal zirconia in the range of pressures from 0 to 50 GPa. We predict a transition to a fluorite-type cubic structure at 37 GPa which is likely to be of a soft mode origin and is accompanied by a power law decrease of the frequency of the Raman-active A(1g) mode. A detailed study of the...

We address the presence of supplier-induced demand in the Belgian primary care market, which is characterized by a …xed fee system and a high density of General Practitioners (GP). Using a unique dataset on the number of visits of all Belgian GPs, we …rst investigate whether we can …nd evidence of demand inducement by Belgian GPs. Novel to this literature is that we furthermore investigate whic...

Résumé. La recherche d’algorithmes d’extraction de connaissances à partir de cubes de données est un domaine actuellement très actif qui trouve de très nombreuses applications dans les entrepôts de données disponibles maintenant dans la plupart des entreprises et milieux scientifiques (biologie, santé, etc.). Nous nous intéressons ici à l’extraction de comportements atypiques (dénommés outliers...

in this research, a 2d laterally averaged model of hydrodynamics and water quality, ce-qual-w2, was applied to simulate water quality parameters in the ilam reservoir. the water quality of ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. the ce-qual-w2 model was calibrated and ver...

This communication sets an evaluation framework and performs a comparative analysis of the UltraSPARC-III and the IA-64 processor architectures. It starts with an overview of a pure RISC architecture and the new EPIC technology. It then presents the unique combination of innovative features that both manufacturers claim explicit parallelism, predication and speculative loading – and the goals f...

Neurons in area MT of primate visual cortex encode the velocity of moving objects. We present a model of how MT cells aggregate responses from V1 to form such a velocity representation. Two diierent sets of units, with local receptive elds, receive inputs from motion energy lters. One set of units forms estimates of local motion, while the second set computes the utility of these estimates. Out...

The distribution of some rare earth elements (La, Ce, Sc, and Y) in the sediment samples, collected form 56 stations in the offshore of the Persian Gulf during the Persian Gulf and Gulf of Oman Oceanographic Cruise (PGGOOS) in 2012, was studied. The elements were determined by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The result revealed that the concentration of Ce (82 µg g-1) was...
