Optimizing H.264/AVC interprediction on a GPU-based framework
2011
H.264/MPEG-4 part 10 is the latest standard for video compression and promises a significant advance in terms of quality and distortion compared with the commercial standards currently most in use such as MPEG-2 or MPEG-4. To achieve this better performance, H.264 adopts a large number of new/improved compression techniques compared with previous standards, albeit at the expense of higher computational complexity. In addition, in recent years new hardware accelerators have emerged, such as graphics processing units (GPUs), which provide a new opportunity to reduce complexity for a large variety of algorithms. However, current GPUs suffer from higher power consumption requirements because of…

Implementing a culture of data in franchise systems : the ingredients for success
2020
The purpose of our research is to improve the understanding of the factors that explain the development of exchange relationships and facilitate the customer data management in franchise Systems. To this end, a literature review was conducted in the field of relationship marketing, and particulary, in relation to Bagozzi's theory of exchange (1974; 1975). Through its lexical and thematic analyses, the qualitative study highlights the principle of reciprocity in exchange in franchisor-franchisee-customer relationships with regard to customer data management. Reciprocity seems to be at the core of exchanges between the franchisor, franchisees and their customers.
Filosofías del don: Usos y abusos de la donación en la ética contemporánea
2013
El objetivo de este artículo es analizar el concepto de donación en la ética contemporánea. Este análisis se realiza en tres momentos: el primero se sitúa en la introducción y muestra que es un concepto importante en el que convergen la fenomenología, el personalismo y la hermenéutica. Esta convergencia no solo supone un uso frecuente del concepto sino un abuso del mismo cuando se construye de espalda a las mediaciones objetivas o institucionales que lo condicionan. El segundo presenta una antropología del don y muestra su relación con los objetos, la reciprocidad, la deuda y la libertad. En el tercer momento se describe la filosofía de la donación de Paul Ricoeur, donde se comprueba un uso…
REP2: A Web Server to Detect Common Tandem Repeats in Protein Sequences
2020
Ensembles of tandem repeats (TRs) in protein sequences expand rapidly to form domains well suited for interactions with proteins. For this reason, they are relatively frequent. Some TRs have known structures and therefore it is advantageous to predict their presence in a protein sequence. However, since most TRs diverge quickly, their detection by classical sequence comparison algorithms is not very accurate. Previously, we developed a method and a web server that used curated profiles and thresholds for the detection of 11 common TRs. Here we present a new web server (REP2) that allows the analysis of TRs in both individual and aligned sequences. We provide currently precomputed analyses f…
2015
Transporters of the ATP-binding cassette (ABC) family such as MDR1 play a pivotal role in persistence of brain homeostasis by contributing to the strict permeability properties of the blood–brain barrier. This barrier on one hand compromises treatment of central nervous system diseases by restricting access of drugs; on the other hand, an impaired or altered function of barrier building cells has been described in neurological disorders. The latter might contribute to increased vulnerability of the brain under pathological conditions or even enforce pathogenesis. Here, we present a novel approach for a systematic examination of drug impact on Mdr1 gene expression by establishing a dual repo…
Designs and methods in school improvement research: a systematic review
2016
Purpose – The purpose of this paper is to focus on challenges faced by longitudinal quantitative analyses of school improvement processes and offers a systematic literature review of current papers that use longitudinal analyses. In this context, the authors assessed designs and methods that are used to analyze the relation between school improvement processes and student outcomes. Based on this the authors point out to what extent the papers consider different aspects of the complex nature of school improvement (e.g. multilevel structure, indirect and nonlinear effects, reciprocity). The choice of study designs and methods of analysis substantially determines which aspects of this complex…
Pre-invasion history and demography shape the genetic variation in the insecticide resistance-related acetylcholinesterase 2 gene in the invasive Col…
2012
Abstract Background Invasive pest species offers a unique opportunity to study the effects of genetic architecture, demography and selection on patterns of genetic variability. Invasive Colorado potato beetle (Leptinotarsa decemlineata) populations have experienced a rapid range expansion and intense selection by insecticides. By comparing native and invasive beetle populations, we studied the origins of organophosphate (OP) resistance-associated mutations in the acetylcholinesterase 2 (AChE2) gene, and the role of selection and demography on its genetic variability. Results Analysis of three Mexican, two US and five European populations yielded a total of 49 haplotypes. Contrary to the exp…
Annihilation at rest of antiprotons and protons into neutral particles
2003
Abstract Annihilation of antiprotons and protons at rest into neutral particles has been studied with the Crystal Barrel detector at LEAR. Annihilation frequencies are determined for final states containing π 0 , η , η ′ and ω mesons using a liquid and a room temperature, 12 bar, gaseous hydrogen target. Including annihilation frequencies for production of neutral kaons from other experiments, the identified reactions for annihilation in liquid hydrogen add up to a branching fraction of (3.56±0.28)% per annihilation compared to the frequency of (3.50±0.30)% with which we observe the all-neutral decay modes inclusively. Since the exclusive final states are normalized to the Crystal Barrel me…
