  • Oubel, E.; Cebral, J.R.; De Craene, Mathieu; Blanc, R.; Blasco, Jordi; Macho, Juan M.; Putman, C.M.; Frangi Caregnato, Alejandro (Institute of Physics (IOP), 2010)
    The quantification of wall motion in cerebral aneurysms is becoming important owing to its potential connection to rupture, and as a way to incorporate the effects of vascular compliance in computational fluid dynamics ...
  • Birulés-Muntané, Joan; Soto-Faraco, Salvador, 1970- (Public Library of Science (PLoS), 2016)
    Watching English-spoken films with subtitles is becoming increasingly popular throughout the world. One reason for this trend is the assumption that perceptual learning of the sounds of a foreign language, English, will ...
  • Espinosa-Anke, Luis; Ronzano, Francesco; Saggion, Horacio (ACL (Association for Computational Linguistics), 2015)
    Definition Extraction (DE) is the task to extract textual definitions from naturally occurring text. It is gaining popularity as a prior step for constructing taxonomies, ontologies, automatic glossaries or dictionary ...
  • Llorach, Gerard; Evans, Alun Thomas; Blat, Josep; Grimm, Giso; Hohmann, Volker (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Virtual characters are an integral part of many games and virtual worlds. The ability to accurately synchronize lip movement to audio speech is an important aspect in the believability of the character. In this paper we ...
  • Evans, Alun Thomas; Agenjo, Javier; Blat, Josep (ACM Association for Computer Machinery, 2014)
    In this paper we present a system for progressive encoding, storage, transmission, and web based visualization of large point cloud datasets. Point cloud data is typically recorded on-set during a film production, and is ...
  • Deco, Gustavo; Scarano, Leandro; Soto-Faraco, Salvador, 1970- (Society for Neuroscience, 2007)
    Recent single-cell studies in monkeys (Romo et al., 2004) show that the activity of neurons in the ventral premotor cortex covaries with the animal's decisions in a perceptual comparison task regarding the frequency of ...
  • Arandía-Romero, Iñigo; Nogueira Mañas, Ramon; Mochol, Gabriela; Moreno Bote, Rubén (Elsevier, 2017)
    Nowadays, it is possible to record the activity of hundreds of cells at the same time in behaving animals. However, these data are often treated and analyzed as if they consisted of many independently recorded neurons. How ...
  • Chicharro Raventós, Daniel; Kreuz, Thomas; Andrzejak, Ralph Gregor (Elsevier, 2011)
    Time scale parametric spike train distances like the Victor and the van Rossum distances/nare often applied to study the neural code based on neural stimuli discrimination./nDifferent neural coding hypotheses, such as rate ...
  • Barbieri, Francesco; Ronzano, Francesco; Saggion, Horacio (ELRA (European Language Resources Association), 2016)
    Emojis allow us to describe objects, situations and even feelings with small images, providing a visual and quick way to communicate. In this paper, we analyse emojis used in Twitter with distributional semantic models. ...
  • Urbano, Julián; Bogdanov, Dmitry; Herrera Boyer, Perfecto; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2014)
    Music Information Retrieval is largely based on descriptors computed from audio signals, and in many practical applications they are to be computed on music corpora containing audio files encoded in a variety of lossy ...
  • Jindal, Nihar; Lozano Solsona, Angel; Marzetta, Thomas L. (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The spectral efficiency achievable with joint processing of pilot and data symbol observations is compared with that achievable through the conventional (separate) approach of first estimating the channel on the basis of ...
  • AbuRa’ed, Ahmed; Chiruzzo, Luis; Saggion, Horacio (ACL (Association for Computational Linguistics), 2017)
    In the current context of scientific information overload, text mining tools are of paramount importance for researchers who have to read scientific papers and assess their value. Current citation networks, which link ...
  • Andrews, Jeffrey G.; Buzzi, Stefano; Choi, Wan; Hanly, Stephen; Lozano Solsona, Angel; Soong, Anthony C.K.; Zhang, Jianzhong Charlie (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    What will 5G be? What it will not be is an incremental/nadvance on 4G. The previous four generations of/ncellular technology have each been a major paradigm shift/nthat has broken backwards compatibility. And indeed, 5G ...
  • Hazan, Amaury; Marxer Piñón, Ricard; Brossier, Paul; Purwins, Hendrick; Herrera Boyer, Perfecto; Serra, Xavier (Taylor & Francis (Routledge), 2009)
    A causal system to represent a stream of music into musical events, and to generate further expected events, is presented. Starting from an auditory front-end that extracts low-level (i.e. MFCC) and mid-level features such ...
  • Aragón, Pablo; Volkovich, Yana; Laniado, David; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    Social media has become a key mechanism for the organization of grassroots movements. In the 2015 Barcelona City Council election, Barcelona en Com´u, an emerging grassroots party, was the most voted one. This candidacy ...
  • Baus, Cristina; Strijkers, Kristof; Costa, Albert, 1970- (Frontiers Media, 2013)
    The aim of the present study was to explore the central (e.g., lexical processing) and peripheral processes (motor preparation and execution) underlying word production during typewriting. To do so, we tested non-professional ...
  • Calabria, Marco; Hernández Pardo, Mireia; Martin, Clara D.; Costa, Albert, 1970- (Frontiers Media, 2011)
    Several studies have documented the advantage of bilingualism with respect to the development of the executive control (EC) system. Two effects of bilingualism have been described in conflict resolution tasks: (a) bilinguals ...
  • Laniado, David; Tasso, Riccardo; Volkovich, Yana; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Talk pages play a fundamental role in Wikipedia as the place for discussion and communication. In this work we use the comments on these pages to extract and study three networks, corresponding to different kinds of ...
  • Chicharro Raventós, Daniel; Ledberg, Anders (Public Library of Science, 2012)
    Biological systems often consist of multiple interacting subsystems, the brain being a prominent example. To understand/nthe functions of such systems it is important to analyze if and how the subsystems interact and to ...
