  • Luvizotto, André Luiz; Rennó Costa, César; Verschure, Paul F. M. J. (Frontiers Media, 2012)
    It has been proposed that the dense excitatory local connectivity of the neo-cortex plays a specific role in the transformation of spatial stimulus information into a temporal representation or a temporal population code ...
  • Venkatesan, Sivarama; Huang, Howard; Lozano Solsona, Angel; Valenzuela, R. A. (Hindawi, 2009)
    It is well known that multiple-input multiple-output (MIMO) techniques can bring numerous benefits, such as higher spectral efficiency, to point-to-point wireless links. More recently, there has been interest in extending ...
  • Biau, Emmanuel; Soto-Faraco, Salvador, 1970- (Elsevier, 2013)
    Spontaneous beat gestures are an integral part of the paralinguistic context during face-to-face conversations. Here we investigated the time course of beat-speech integration in speech perception by measuring ERPs evoked ...
  • Hoogendoorn, Corné; Sukno, Federico M.; Ordás, Sebastián; Frangi Caregnato, Alejandro (Springer, 2009)
    In this work we describe the usage of bilinear statistical models as a means of factoring the shape variability into two components attributed to inter-subject variation and to the intrinsic dynamics of the human heart. ...
  • Burgaleta, Miguel; Sanjuán, Ana; Ventura Campos, Noelia; Sebastián Gallés, Núria; Ávila, César (Elsevier, 2016)
    Naturally acquiring a language shapes the human brain through a long-lasting learning and practice process. This is supported by previous studies showing that managing more than one language from early childhood has an ...
  • Costalat, V.; Sánchez, M.; Ambard, D.; Thines, L.; Lonjon, N.; Nicoud, F.; Brunel, H.; Lejeune, J. P.; Dufour, H.; Bouillot, P.; Lhaldky, J. P.; Kouri, K.; Segnarbieux, F.; Mourage, C. A.; Lobostein, K.; Villa-Uriol, Maria-Cruz; Zhang, Chong; Frangi Caregnato, Alejandro; Mercier, G.; Bonafé, A.; Sarry, L.; Jourdan, F. (Elsevier, 2011)
    Background and purpose: Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength ...
  • Nakagawa, Tristan T.; Jirsa, Viktor K.; Spiegler, Andreas; McIntosh, Anthony R.; Deco, Gustavo (Elsevier, 2013)
    With the increasing availability of advanced imaging technologies, we are entering a new era of neuroscience. Detailed descriptions of the complex brain network enable us to map out a structural connectome, characterize ...
  • Tulino, Antonia M.; Lozano Solsona, Angel; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    We characterize the capacity-achieving input covariance for multi-antenna channels known instantaneously at the receiver and in distribution at the transmitter. Our characterization, valid for arbitrary numbers of antennas, ...
  • Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2003)
    The simultaneous use of multiple transmit and receive antennas can unleash very large capacity increases in rich multipath environments. Although such capacities can be approached by layered multi-antenna architectures ...
  • Huguet, Marina; Tobón Gómez, Catalina, 1981-; Bijnens, Bart; Frangi Caregnato, Alejandro; Petit i Guinovart, Màrius (BioMed Central, 2009)
    Blunt chest traumas are a clinical challenge, both for diagnosis and treatment. The use of Cardiovascular Magnetic Resonance can play a major role in this setting. We present two cases: a 12-year-old boy and 45-year-old ...
  • Oubel, E.; De Craene, Mathieu; Hero, A.O.; Pourmorteza, A.; Huguet, Marina; Avegliano, G.; Bijnens, Bart; Frangi Caregnato, Alejandro (Elsevier, 2011)
    Image registration has been proposed as an automatic method for recovering cardiac displacement fields from Tagged Magnetic Resonance Imaging (tMRI) sequences. Initially performed as a set of pairwise registrations, these ...
  • Piella Fenoy, Gemma; De Craene, Mathieu; Bijnens, Bart; Tobón Gómez, Catalina, 1981-; Huguet, Marina; Avegliano, G.; Frangi Caregnato, Alejandro (Elsevier, 2010)
    Introducción y objetivos. Se ha señalado que, en la miocardiopatía hipertrófica (MCH), la desorganización de las fibras regionales da lugar a segmentos en los que la deformación es nula o está gravemente reducida, y que ...
  • Martin, David; Aiello, Luca Maria; Grabowicz, Przemyslaw; Jaimes, Alejandro; Baeza-Yates, Ricardo (SpringerOpen, 2014)
    Social groups play a crucial role in online social media because they form the basis for user participation and engagement. Although widely studied in their static and evolutionary aspects, no much attention has been devoted ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia; Herrera Boyer, Perfecto; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We present a new technique for audio signal comparison based on tonal subsequence alignment and its application to detect cover versions (i.e., different performances of the same underlying musical piece). Cover song ...
  • Nácher, Verónica; Ledberg, Anders; Deco, Gustavo; Romo, Ranulfo (National Academy of Sciences, 2013)
    Coherent oscillations in the theta-to-gamma frequency range have been proposed as a mechanism that coordinates neural activity in large-scale cortical networks i n sensory, motor, and cognitive tasks. Whether this ...
  • Jorrín-Abellán, Iván M.; Ruiz-Requies, Inés; Hernández Leo, Davinia; Villasclaras-Fernández, Eloy D.; Dimitriadis, Yannis; Rubia-Avi, Bartolomé; Asensio-Pérez, Juan I. (International Forum of Educational Technology & Society, 2006)
    This paper introduces Collage, a high-level IMS-LD compliant authoring tool that is specialized for CSCL (Computer-Supported Collaborative Learning). Nowadays CSCL is a key trend in elearning since it highlights the ...
  • Faridi, Azadeh; Palattella, Maria Rita; Lozano Solsona, Angel; Dohler, Mischa; Boggia, Gennaro; Grieco, Luigi Alfredo; Camarda, Pietro (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Supported by IEEE 802.15.4 standardization activities, embedded networks have been gaining popularity in recent years. The focus of this paper is to quantify the behavior of key networking metrics of IEEE 802.15.4 ...
  • Hernández Leo, Davinia; Asensio-Pérez, Juan I.; Dimitriadis, Yannis (International Forum of Educational Technology & Society, 2005)
    The identification and integration of reusable and customizable CSCL (Computer Supported Collaborative Learning) may benefit from the capture of best practices in collaborative learning structuring. The authors have proposed ...
  • Morales-Jiménez, David; Lopez-Martínez, F. Javier; Martos-Naya, Eduardo; Paris, José F.; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper presents a new connection between the generalized Marcum-Q function and the confluent hypergeometric function of two variables, Φ3. This result is then applied to the closed-form characterization of the bivariate ...
  • Theodoni, Panagiota; Panagiotaropoulos, Theofanis I.; Kapoor, Vishal; Logothetis, N.; Deco, Gustavo (Frontiers Media, 2011)
    Perceptual bistability arises when two conflicting interpretations of an ambiguous stimulus or images in binocular rivalry (BR) compete for perceptual dominance. From a computational point of view, competition models based ...
