Due to the new generation of mobile devices such as smartphones and tablets, users are no longer constrained to their traditional devices such as PCs and laptops in order to access the information they need. This has given rise to a new trend in Business Intelligence (BI) coined mobile BI. This new term reflects an organizing vision, created by a broad community, which is prominent during the c...

this study was conducted in order to investigate the influence of plastic deformation on the transformation of retained austenite in a trip steel with a high content of al and a low content of si. to the aim, appropriate treatments were used to produce the starting material (trip steel). the microstructure of the obtained steel was composed of bainite and phases including ferrite and retained a...

The number and volume of fibrillar centres, the structural components of interphase cell nucleoli on the surface of which rRNA is synthesized, have been studied in differentiating erythroblasts of mouse embryo liver. Complete series of ultrathin sections of erythroblast nuclei have been used at the main stages of differentiation: proerythroblast, basophilic erythroblast, polychromatophilic eryt...

This paper introduces the concept of dynamic embedding manifold (DEM), which allows the Kohonen self-organizing map (SOM) to learn dynamic, nonlinear input-ouput mappings. The combination of the DEM concept with the SOM results in a new modelling technique that we called Vector-Quantized Temporal Associative Memory (VQTAM). We use VQTAM to propose an unsupervised neural algorithm called Self-Or...

In this study we have demonstrated that in native bile, lipids are organized in the form of a lipoprotein (bile LP) carrying albumin as apoprotein. The lipid composition of bile LP is almost identical to lipoprotein-X (LP-X, the characteristic lipoprotein of cholestasis). However, it differs from LP-X inits protein/lipid ratio and immunological and electrophoretic characteristics. Bile lipoprot...

during an 11 days mission in february 2000 the shuttle radar topography mission (srtm) collected data over 80% of the earth's land surface, for all areas between 60 degrees n and 56 degrees s latitude. since srtm data became available, many studies utilized them for application in topography and morphometric landscape analysis. exploiting srtm data for recognition and extraction of topographic ...

The potential value of screening for lung cancer with low-dose CT scans is currently a topic of much research and debate. This article reviews the existing trials of lung cancer screening, using chest x-ray and low-dose CT scan. Potential harms of screening, including overdiagnosis and radiation exposure, are addressed. Practical difficulties of organizing a screening program in Canada include ...

We study a spatial cyclic predator-prey model with an even number of species (for n=4, 6, and 8) that allows the formation of two defensive alliances consisting of the even and odd label species. The species are distributed on the sites of a square lattice. The evolution of spatial distribution is governed by iteration of two elementary processes on neighboring sites chosen randomly: if the sit...

Lanthanum (La) doped Ceria (CeO2) has attracted considerable interest as a candidate material for thermal barrier coating (TBC) because of its low thermal conductivity and potential capability to be operated above 1250°C. In this study, La2Ce2O7 powder was synthesized through the ball mill method. The crystal structure of La3+ su...

We report the growth and characterization of a new photorefractive material, potassium lithium tantalate niobate (KLTN). A KLTN crystal doped with copper is demonstrated to yield high diffraction efficiency of photorefractive gratings in the paraelectric phase. Voltage-controllable index gratings with n(1) = 8.5 x 10(-5) were achieved, which yielded diffraction efficiencies of 75% in a 2.9-mm-t...
