  • Pailhez, Guillem; Majó, Albert; Córcoles, David; Ginés Miranda, José María; Arcega, José M.; Castaño Asins, Juan Ramón; Merino Torres, Ana; Bulbena Vilarrasa, Antonio; Pérez, Victor (Elsevier Masson, 2015)
    INTRODUCTION: To analyze factors associated with clinical observation, pharmacotherapy and referral on discharge of patients with anxiety disorder (AD) seeking care at a psychiatric emergency unit. METHOD: A total of 5003 ...
  • Escuriet, Ramón; Pueyo, María; Biescas, Herminia; Colls, Cristina; Espiga, Isabel; White, Joanna; Espada, Xavi; Fusté, Josep; Ortún Rubio, Vicente (BioMed Central, 2014)
    Background: Childbirth assistance in highly technological settings and existing variability in the interventions performed are cause for concern. In recent years, numerous recommendations have been made concerning the ...
  • Eeckhout, Jan; Jovanovic, Boyan (Elsevier, 2012)
    The rise in world trade since 1970 has been accompanied by a rise in the geographic span of control of management and, hence, also a rise in the e ective international mobility of labor services. We study the e ect of such ...
  • Cramer, Ronald; Daza, Vanesa; Gracia, Ignacio; Jiménez Urroz, Jorge; Leander, Gregor; Martí-Farré, Jaume; Padró, Carles (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    Error-correcting codes and matroids have been widely used in the study of ordinary secret sharing schemes. In this paper, the connections between codes, matroids, and a special class of secret sharing schemes, namely, ...
  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We focus on full-rate, fast-decodable space–time block codes (STBCs) for 2 x 2 and 4 x 2 multiple-input multiple-output (MIMO) transmission. We first derive conditions and design criteria for reduced-complexity maximum-likelihood ...
  • Deco, Gustavo; Jirsa, Viktor K. (Society for Neuroscience, 2012)
    The ongoing activity of the brain at rest, i.e., under no stimulation and in absence of any task, is astonishingly highly structured into spatiotemporal patterns. These spatiotemporal patterns, called resting state networks, ...
  • Sezginer, Serdar; Sari, Hikmet; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The 2×2 MIMO profiles included in Mobile WiMAX specifications are Alamouti’s space-time code (STC) fortransmit diversity and spatial multiplexing (SM). The former has full diversity and the latter has full rate, but neither ...
  • Albà Soler, Mar; Castresana, José (BioMed Central, 2007)
    Background: It has been shown in a variety of organisms, including mammals, that genes that appeared recently in evolution, for example orphan genes, evolve faster than older genes. Low functional constraints at the time ...
  • Andriyanova, Iryna; Biglieri, Ezio; Boutros, Joseph Jean (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper presents our investigation on iterative decoding performances of some sparse-graph codes on block-fading Rayleigh channels. The considered code ensembles are standard LDPC codes and Root-LDPC codes, first ...
  • Daza, Vanesa; Herranz, Javier; Sáez, Germán (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    In a distributed key distribution scheme, a set of servers helps a set of users in a group to securely obtain a common key. Security means that an adversary who corrupts some servers and some users has no information about ...
  • Grasas Leon, Alex; Ramalhinho, Helena; Pessoa, Luciana S; Resende, Mauricio GC; Caballé, Imma; Barba, Nuria (BioMed Central, 2014)
    Background: Blood samples are usually collected daily from different collection points, such hospitals and health centers, and transported to a core laboratory for testing. This paper presents a project to improve the ...
  • Torner Castells, Sergi (Walter de Gruyter, 2005)
    The morphological status of adverbs ending in -mente in Spanish (-ly in English) has been the object of many studies and continues to be the subject of debate. The two main proposals regarding the morphology of these adverbs ...
  • Van Geenhoven, Veerle; McNally, Louise, 1965- (Elsevier, 2005)
    In this paper, we regard Zimmermann’s (1993) property analysis of verbs of absence as a special case of the independent ability of verbs to take property-type complements (see Ladusaw, 1994). By integrating into this ...
  • Guegan, Thomas, 1983-; Cutando, Laura; Gangarossa, Giuseppe; Santini, Emanuela; Fisone, Gilberto; Martínez, Albert; Valjent, Emmanuel; Maldonado, Rafael, 1961-; Martín Sánchez, Miquel, 1971- (Elsevier, 2013)
    Food palatability produces behavioral modifications that resemble those induced by drugs of abuse. Palatability-induced behavioral changes require both, the activation of the endogenous cannabinoid system, and changes in ...
  • Guegan, Thomas, 1983-; Cutando, Laura; Ayuso, Eduard; Santini, Emanuela; Fisone, Gilberto; Bosch, Fatima; Martínez, Albert; Valjent, Emmanuel; Maldonado, Rafael, 1961-; Martín Sánchez, Miquel, 1971- (Elsevier, 2013)
    Palatability enhances food intake by hedonic mechanisms that prevail over caloric necessities. Different studies have demonstrated the role of endogenous cannabinoids in the mesocorticolimbic system in controlling food ...
  • Burokas, Aurelijus, 1982-; Gutiérrez Cuesta, Javier; Martín García, Elena, 1975-; Maldonado, Rafael, 1961- (Wiley-Blackwell, 2012)
    One aspect of the addictive process that has not been thoroughly investigated is the consequence of the frustrated state occurring when the drug is not available. The present study aimed to validate a novel operant model ...
  • Bura, S. Andreea, 1978-; Guegan, Thomas, 1983-; Zamanillo, Daniel; Vela, José M.; Maldonado, Rafael, 1961- (Wiley-Blackwell, 2013)
    BACKGROUND: The treatment of neuropathic pain is unsatisfactory at the present moment and the sigma 1 receptor has been identified as a new potential target for neuropathic pain. The aim of this study was to use an operant ...
  • Serra, Xavier (Universitat Pompeu Fabra, 2012)
    The current research in Music Information Retrieval (MIR) is showing the potential that the Information Technologies can have in music related applications. A major research challenge in that direction is how to ...
  • Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interest (e.g., fading rate, signal-to-noise ratio) is quantified. The ...
