  • Bulatov, Andrei A.; Dalmau, Víctor (Elsevier, 2007)
    The Counting Constraint Satisfaction Problem (#CSP) can be expressed as follows: given a set of variables, a set of values that can be taken by the variables, and a set of constraints specifying some restrictions on the ...
  • Bulatov, Andrei; Chen, Hubie; Dalmau, Víctor (Elsevier, 2007)
    Intersection-closed classes of concepts arise naturally in many contexts and have been intensively studied in computational learning theory. In this paper, we study intersection-closed classes that contain the concepts ...
  • Bonet, Blai; Geffner, Héctor (Elsevier, 2001)
    In the AIPS98 Planning Contest, the hsp planner showed that heuristic search planners can be competitive with state-of-the-art Graphplan and sat planners. Heuristic search planners like hsp transform planning problems into ...
  • Bailey, Delbert D.; Dalmau, Víctor; Kolaitis, Phokion G. (Elsevier, 2007)
    The complexity class PP consists of all decision problems solvable by polynomial-time probabilistic Turing machines. It is well known that PP is a highly intractable complexity class and that PP-complete problems are in ...
  • Guerrero-Apolo, J. David; Navarro-Pastor, J. Blas; Bulbena Vilarrasa, Antonio; Gabarre-Mir, Julian (Associação Brasileira de Psiquiatria, 2018)
    OBJECTIVE: Impulsiveness has been the subject of much research, but little is known about the possible relationship between craniofacial anatomy and impulsiveness. The present study was designed to investigate the relationship ...
  • Hernáez , Álvaro; Delgado, Juan F.; Cinca, Juan; Fernández-Avilés, Francisco; Marrugat de la Iglesia, Jaume (Elsevier, 2018)
    BACKGROUND AND OBJECTIVES: Hyperkalaemia (K+ levels≥5.5mmol/L) is a severe ion imbalance that occurs in patients who have heart failure (HF) with reduced ejection fraction (HFrEF) and increases the risk of ventricular ...
  • Carvalho, Catarina; Dalmau, Víctor; Krokhin, Andrei (Elsevier, 2010)
    We study non-uniform constraint satisfaction problems definable in monadic Datalog stratified by the use of non-linearity. We show how such problems can be described in terms of homomorphism dualities involving trees of ...
  • Inoue, Atsushi; Rossi, Barbara, 1971- (Taylor & Francis, 2005)
    We propose a sequential test for predictive ability for recursively assessing whether some economic variables have explanatory content for another variable. In the forecasting literature it is common to assess predictive ...
  • Pesavento, Elena; Rossi, Barbara, 1971- (Cambridge University Press, 2005)
    This paper analyzes the robustness of the estimate of a positive productivity shock on hours to the presence of a possible unit root in hours. Estimations in levels or in first differences provide opposite conclusions. We ...
  • Xue, Yali; Prado Martínez, Javier, 1987-; de Manuel, Marc; Hernández Rodríguez, Jéssica, 1983-; Lobón, Irene; Marquès i Bonet, Tomàs, 1975-; Scally, Aylwyn (American Association for the Advancement of Science (AAAS), 2015)
    Mountain gorillas are an endangered great ape subspecies and a prominent focus for conservation, yet we know little about their genomic diversity and evolutionary past. We sequenced whole genomes from multiple wild individuals ...
  • Cournia, Zoe; Selent, Jana; Bondar, Ana-Nicoleta (Springer, 2015)
    Membrane proteins mediate processes that are fundamental for the flourishing of biological cells. Membrane-embedded transporters move ions and larger solutes across membranes; receptors mediate communication between the ...
  • Koepfli, Klaus-Peter; Paten, Benedict; Genome 10K Community of Scientists; O'Brien, Stephen J.; Marquès i Bonet, Tomàs, 1975- (Annual Reviews Inc, 2015)
    The Genome 10K Project was established in 2009 by a consortium of biologists and genome scientists determined to facilitate the sequencing and analysis of the complete genomes of 10,000 vertebrate species. Since then the ...
  • Prindle, Arthur; Liu, Jintao; Asally, Munehiro; Ly, San; Garcia Ojalvo, Jordi; Süel, Gürol M. (Nature Research, 2015)
    The study of bacterial ion channels has provided fundamental insights into the structural basis of neuronal signalling; however, the native role of ion channels in bacteria has remained elusive. Here we show that ion ...
  • Steels, Luc (Elsevier, 1995)
    The paper explores a biologically inspired definition of intelligent autonomous agents. Intelligence is related to whether behavior of a system contributes to its self-maintenance. Behavior becomes more intelligent (or ...
  • Castro Domínguez, Francisco; Melo, Luciano; Eyles, Jillian P. (Elsevier, 2018)
  • Malagón, Angeles; Martín López, Luis Miguel; Córcoles, David; Gonzalez Fresnedo, Ana María; Bellsolà González, Magdalena; Teo, Alan R.; Pérez Solá, Victor; Bulbena Vilarrasa, Antonio; Bergé, Daniel (Elsevier, 2018)
    Social withdrawal is a new mental health problem increasingly common, present in different cultures, whose psychopathology and treatment is not yet established. This study aims to determine the socio-demographic and clinical ...
  • Fuente Valentín, Luis de la; Pérez-Sanagustín, Mar; Hernández-Leo, Davinia; Pardo Sánchez, Abelardo; Blat, Josep; Delgado Kloos, Carlos (Elsevier, 2014)
    Computer Supported Collaborative Blended Learning (CSCBL) scripts are innovative practices that benefit from interactive devices to combine and coordinate activities occurring in different spatial locations. However, the ...
  • Assinnato, Gisela; Mateus, Julio César; Novomisky, Sebastian (Universitat de Girona, 2018)
    Este trabajo explora los usos, las prácticas y las percepciones que los docentes universitarios de Comunicación dan a las TIC. Los objetivos son, por un lado, reconocer los sentidos que los profesores del nivel superior ...
  • Badell, Joan-Isidre (UNLISTED PUBLISHER, 2015)
    Se muestran los principales resultados obtenidos en la investigación sobre la presencia de los museos de Cataluña en las redes sociales y de la visibilidad de sus sedes web. La metodología se ha basado en la obtención de ...
  • Badell, Joan-Isidre (Taylor & Francis, 2015)
    The main goal of this article is to describe the current situation of Catalan museums in social media. The study and analysis was developed following both a quantitative and a qualitative methodology, by creating parameters ...
