      Research into the genetic factors that regulate food intake is arousing great interest. The polymorphism -1438G>A in the serotonin 2A receptor or 5-hydroxytriptamine (5-HT) type 2A receptor (5-HTR2A) gene has been ...

    • closedAccess   Stability bounds in networks with dynamic link capacities 

      Cholvi, Vicent Elsevier (2008)
      We address the problem of stability in networks where the link capacities can change dynamically. We show that every network running a greedy scheduling policy is universally stable at any injection rate r < 1 / (C d), ...

      This paper surveys the most relevant research on combining Data Warehouse (DW) and Web data. It studies the XML technologies that are currently being used to integrate, store, query, and retrieve Web data and their ...

    • openAccess   Assessment of disease named entity recognition on a corupus of annotated sentences 

      Jiménez Ruiz, Ernesto; Jimeno Yepes, Antonio José; Lee, Vivian; Gaudan, Sylvain; Berlanga Llavori, Rafael; Rebholz-Schuhmann, Dietrich BioMed Central (2008)
      Background: In recent years, the recognition of semantic types from the biomedical scientific literature has been focused on named entities like protein and gene names (PGNs) and gene ontology terms (GO terms). Other ...

    • openAccess   Influence of color spaces over texture characterization 

      Rajadell Rojas, Olga; García-Sevilla, Pedro Instituto Politécnico Nacional (Mèxic). Centro de Investigación en Computación (2008)
      Images are generally represented in the RGB color space. This is the model commonly used for most cameras and for displaying on computer screens. Nevertheless, the representation of color images using this color space has ...

    • openAccess   A Tool for the Creation and management of level-of-detail models for 3D applications 

      Ripollés Mateu, Oscar Enrique World Scientific and Engineering Academy and Society (WSEAS) (2008)
      Real-time visualization of 3D scenes is a very important feature of many computer graphics solutions. Current environments require complex scenes which contain an increasing number of objects composed of thousands or ...
