First principles simulations of 2D Cu superlattices on the MgO(0 0 1) surface
2004
AbstractFirst principles slab simulations of copper 2D superlattices of different densities on the perfect MgO(001) surface are performed using the DFT method as implemented into the CRYSTAL98 computer code. In order to clarify the nature of interfacial bonding, we consider regular 1/4, 1/2 and 1 monolayer (ML) coverages and compare results of our calculations with various experimental and theoretical data. Our general conclusion is that the physical adhesion associated with a Cu polarization and charge redistribution gives the predominant contribution to the bonding of the regular Cu 2D layer on the MgO(001) surface.
Functional consequences of prey acclimation to ocean acidification for the prey and its predator
2016
Ocean acidification is the suite of chemical changes to the carbonate system of seawater as a consequence of anthropogenic carbon dioxide (CO2) emissions. Despite a growing body of evidences demonstrating the negative effects of ocean acidification on marine species, the consequences at the ecosystem level are still unclear. One factor limiting our ability to upscale from species to ecosystem is the poor mechanistic understanding of the functional consequences of the observed effects on organisms. This is particularly true in the context of species interactions. The aim of this work was to investigate the functional consequence of the exposure of a prey (the mussel Brachidontes pharaonis) t…

Programa de entrenamiento en comunicación a padres: una vía de prevención de la agresión
2013
El presente estudio tuvo por objetivo diseñar un programa de entrenamiento en solución de conflictos y mediación familiar. La finalidad del programa fue evaluar la relación existente entre el entrenamiento recibido por parte de los padres del Colegio Sagrada Familia de Manises y el Colegio San José de la Montaña de Cheste, en habilidades de resolución de conflictos y mediación familiar, y la disminución de la agresividad en sus hijos. El diseño utilizado para la realización de la investigación fue un diseño pretest-intervención-postest con un grupo de control. La muestra incluía 69 sujetos de edades comprendidas entre los 31 a los 47 años, 20 experimentales y 49 de control. Para medir el ca…
Chromoendoscopy: What Is Its True Value for Ulcerative Colitis Surveillance?
2010
Advanced imaging technologies are enabling targeted biopsies or endoscopic resections due to better visualization of the mucosal architecture. This new concept of ‘smart biopsies’ is in particular important for patients with higher risk for development cancer (e.g. ulcerative colitis) but can also be beneficial for screening purposes. This short review will focus on new imaging modalities like chromoendoscopy, digital chromoendoscopy, high-definition endoscopy and confocal laser endomicroscopy in the lower GI tract which will be crucial in the future to detect colorectal neoplasia earlier then before.
External knowledge sourcing in different national settings: a comparison of electronics establishments in Britain and France
2004
04001; International audience; In a detailed comparison of matched samples of electronics establishments in Britain and France, this paper finds that the two samples of establishments were operating in distinctively different national labour markets for engineers and scientists, reflecting structural differences in national higher education systems and a far higher level of individual mobility between enterprises in Britain than is found in France. These differences were found to have very little effect on quantitative measures of establishments' external research interactions which tended to reflect other national-institutional differences such as continued government support for public la…
Kustīgu objektu noteikšana
2015
Programma ir paredzēta video analīzei, kustīgu objektu atpazīšanai un uzskaitei. Programma spēj darboties reāllaikā, analizējot jau ierakstītu video materiālu vai materiālu no tīmekļa kameras. Lietotājam ir dotas iespējas mainīt vairākas iestatījumu vērtības, kuras tiek izmantotas video apstrādē, piemēram, mainīt minimālo izmēru objektu atpazīšanai priekšplāna maskā, noteikt robežas izmēru, kādā pikseļu vērtības tiek uzskatītas par fonu. Šis dokuments satur programmatūras prasību specifikāciju, programmatūras projektējuma aprakstu, testēšanas dokumentāciju, kā arī citu svarīgu informāciju par programmu.
Connected-component identification and cluster update on graphics processing units.
2011
Cluster identification tasks occur in a multitude of contexts in physics and engineering such as, for instance, cluster algorithms for simulating spin models, percolation simulations, segmentation problems in image processing, or network analysis. While it has been shown that graphics processing units (GPUs) can result in speedups of two to three orders of magnitude as compared to serial codes on CPUs for the case of local and thus naturally parallelized problems such as single-spin flip update simulations of spin models, the situation is considerably more complicated for the nonlocal problem of cluster or connected component identification. I discuss the suitability of different approaches…
Farsighted R&D networks
2014
We analyze the formation of bilateral R&D collaborations in an oligopoly when each firm benefits from the research done by other firms it is connected to. In contrast to myopic stability, farsighted stability leads to R&D networks consisting of two minimally connected components, with the largest one comprising three-quarters of firms.
Physical integration: A causal account for consciousness
2014
The issue of integration in neural networks is intimately connected with that of consciousness. In this paper, integration as an effective level of physical organization is contrasted with a methodological integrative approach. Understanding how consciousness arises out of neural processes requires a model of integration in just causal physical terms. Based on a set of feasible criteria (physical grounding, causal efficacy, no circularity and scaling), a causal account of physical integration for consciousness centered on joint causation is outlined.
