  • Biglieri, Ezio (National Institute of Information and Communications Technology (NICT), 2008)
    We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number of active interferers. Using a statistical-physics approach, we compute the single-user channel ...
  • Invergo, Brandon M., 1982-; Montanucci, Ludovica; Laayouni, Hafid, 1968-; Bertranpetit, Jaume, 1952- (BioMed Central, 2013)
    Visual perception is initiated in the photoreceptor cells of the retina via the phototransduction system. This system has shown marked evolution during mammalian divergence in such complex attributes as activation time ...
  • Wang, Ni-Chun; Biglieri, Ezio; Yao, Kung (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    A systolic array to implement lattice-reduction-aided linear detection is proposed for a MIMO receiver. The lattice reduction algorithm and the ensuing linear detections are operated in the same array, which can be ...
  • Sikora, Martin; Laayouni, Hafid; Menéndez, Clara; Mayor, Alfredo; Bardaji, Azucena; Sigauque, Betuel; Netea, Mihai G.; Casals López, Ferran; Bertranpetit, Jaume (Public Library of Science (PLoS), 2011)
    A large proportion of the death toll associated with malaria is a consequence of malaria infection during pregnancy, causing up to 200,000 infant deaths annually. We previously published the first extensive genetic association ...
  • Morales, Oscar Alberto; Cassany, Daniel; González-Peña, Carolina (AELFE, 2007)
    Describimos el uso de estrategias de atenuación en 40 artículos de revisión (AR), publicados en español en revistas iberoamericanas entre 1994 y 2004. Identificamos las estrategias empleadas en las secciones retóricas por ...
  • Berrendero Díaz, Fernando; Kieffer, Brigitte L.; Maldonado, Rafael, 1961- (Society for Neuroscience, 2002)
    The involvement of μ-opioid receptors in different behavioral responses elicited by nicotine was explored by using μ-opioid receptor knock-out mice. The acute antinociceptive responses induced by nicotine in the tail-immersion ...
  • Capdeferro i Pla, Josep (Institución Fernando el Católico, 2001)
    La nostra comunicació s'emmarca en la Catalunya deIs inicis del regnat de Felip II (III de Castella). Té per objecte la complexa situació que es produeix quan, amb motiu d'una convocatoria de Corts, la Diputació del General ...
  • Gulati, Sankalp; Salamon, Justin; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for a complete iterative system for the same. Our method splits the task of tonic pitch identification into two ...
  • Jindal, Nihar; Lozano Solsona, Àngel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in single-user 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 ...
  • Ozaita Mintegui, Andrés; Petit-Jacques, Jerome; Völgyi, Béla; Ho, Chi Sun; Joho, Rolf H.; Bloomfield, Stewart A.; Rudy, Bernardo (Society for Neuroscience, 2004)
    Direction-selective retinal ganglion cells show an increased activity evoked by light stimuli moving in the preferred direction. This selectivity is governed by direction-selective inhibition from starburst amacrine cells ...
  • Aliagas Marin, Cristina; Castellà, Josep M.; Cassany, Daniel (Universidad de Castilla La Mancha, 2009)
    Exploramos con un estudio de caso la lectura como práctica social en la vida de un adolescente que acaba de abandonar los estudios en 1º de Bachillerato. Desde el prisma teórico de los Nuevos Estudios de Literacidad, ...
  • Bogunovic, Hrvoje; Pozo Soler, José Ma. (José María); Villa-Uriol, Maria-Cruz; Majoie, Charles B. L. M.; van den Berg, Rene; Gratama van Andel, Hugo A. F.; Macho, Juan M.; Blasco, Jordi; San Román, Luis; Frangi Caregnato, Alejandro (American Association of Physicists in Medicine (AAPM), 2010)
    Purpose: To evaluate the suitability of an improved version of an automatic segmentation method based on geodesic active regions (GAR) for segmenting cerebral vasculature with aneurysms from 3D X-ray reconstruc- tion ...
  • Bel Rafecas, Núria; Coll, Maria; Resnik, Gabriela (ACL (Association for Computational Linguistics), 2010)
    In this work we present the results of experimental work on the development of lexical class-based lexica by automatic means. Our purpose is to assess the use of linguistic lexical-class based information as a feature ...
  • Vázquez, Silvia; Padró, Muntsa; Bel Rafecas, Núria; Gonzalo, Julio (ACL (Association for Computational Linguistics), 2012)
    Automatic creation of polarity lexicons is a crucial issue to be solved in order to reduce time and efforts in the first steps of Sentiment Analysis. In this paper we present a methodology based on linguistic cues that ...
  • Bauer-Mehren, Anna; van Mullingen, Erik M.; Avillach, Paul; Carrascosa, María del Carmen; García Serna, Ricard; Piñero, Janet; Singh, Barat; Lopes, Pedro; Oliveira, José Luis; Diallo, Gayo; Ahlberg Helgee, Ernst; Boyer, Scott; Mestres, Jordi; Sanz, Ferran; Kors, Jan A.; Furlong, Laura I. (Public Library of Science (PLoS), 2012)
    Drug safety issues pose serious health threats to the population and constitute a major cause of mortality worldwide. Due to the prominent implications to both public health and the pharmaceutical industry, it is of great ...
  • Bel Rafecas, Núria; Romeo, Lauren; Padró, Muntsa (ELRA (European Language Resources Association), 2012)
    The work we present here addresses cue-based noun classification in English and Spanish. Its main objective is to automatically acquire lexical semantic information by classifying nouns into previously known noun lexical ...
  • Igual, Laura; Preciozzi, Javier; Garrido, Luís; Almansa, Andrés; Caselles, Vicente; Rougé, Bernard (AIMS American Institute of Mathematical Sciences, 2007)
    In this work we propose a new automatic methodology for computing accurate digital elevation models (DEMs) in urban environments from low baseline stereo pairs that shall be available in the future from a new kind of earth ...
  • Sikora, Martin; Ferrer Admetlla, Anna; Laayouni, Hafid; Menéndez, Clara; Mayor, Alfredo; Bardaji, Azucena; Sigauque, Betuel; Mandomando, Inacio; Alonso, Pedro L.; Bertranpetit, Jaume; Casals López, Ferran (Oxford University Press, 2009)
