  • Gerber, Nicolas; Reyes, Mauricio; Barazzetti, Livia; Kjer, Hans Martin; Vera, Sergio; Stauber, Martin; Mistrik, Pavel; Ceresa, Mario; Mangado, Nerea; Wimmer, Wilhelm; Stark, Thomas; Paulsen, Rasmus; Weber, Stefan; Caversaccio, Marco; González Ballester, Miguel Ángel, 1973- (Nature Publishing Group, 2017)
    Understanding the human inner ear anatomy and its internal structures is paramount to advance hearing implant technology. While the emergence of imaging devices allowed researchers to improve understanding of intracochlear ...
  • Penacchio, Olivier; Otazu, Xavier; Dempere-Marco, Laura (Public Library of Science, 2013)
    Brightness induction is the modulation of the perceived intensity of an area by the luminance of surrounding areas. Recent/nneurophysiological evidence suggests that brightness information might be explicitly represented ...
  • Cyriac, Praveen; Batard, Thomas; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2014)
    Due to technical limitations, common display devices can only reproduce images having a low range of intensity values (dynamic range). As a consequence, the dynamic range of images encoding real world scenes, which is ...
  • Evans, Alun Thomas; Agenjo, Javier; Blat, Josep (2017)
    We present an end-to-end pipeline for the export of 3D scenes from content creaton tools to a real-tme rendering engine in an embeddable web-page, including a novel system for compression/decompression of textured polygonal ...
  • Melero Gallardo, Javier; Hernández Leo, Davinia; Blat, Josep (Graz University of Technology. Institut für Informationssysteme und Computer Medien (IICM), 2012)
    Information and Communication Technology (ICT) engineering education is facing/na decreasing interest by students. To deal with this issue, a need for shifting from traditional/nlearning approaches to constructivist methods ...
  • Rennó Costa, César; Lisman, John E.; Verschure, Paul F. M. J. (Public Library of Science, 2014)
    The notion of attractor networks is the leading hypothesis for how associative memories are stored and recalled. A defining/nanatomical feature of such networks is excitatory recurrent connections. These ‘‘attract’’ the ...
  • Marques, Ricardo; Bouville, Christian; Ribardière, Mickaël; Santos, Luís Paulo; Bouatouch, Kadi (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    The Monte Carlo method has proved to be very powerful to cope with global illumination problems but it remains costly in terms of sampling operations. In various applications, previous work has shown that Bayesian Monte ...
  • Jindal, Nihar; Lozano Solsona, Angel (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 ...
  • Sarnago, Héctor; Lucía, Óscar; Naval, Alejandro; Burdío, José Miguel; Castellví Fernández, Quim; Ivorra Cano, Antoni, 1974- (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Electroporation is an effective technique based on applying an electric field to cells, commonly used to increase the effectivity of drug and gene delivery. When the applied electric field is ...
  • 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 ...
  • Demirtaş, Murat; Falcón, Carles; Tucholka, Alan; Domingo Gispert, Juan; Molinuevo, José Luis; Deco, Gustavo (Elsevier, 2017)
    Alzheimer's disease (AD) is the most common dementia with dramatic consequences. The research in structural and functional neuroimaging showed altered brain connectivity in AD. In this study, we investigated the whole-brain ...
  • 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 ...
  • Kalinić, Hrvoje; Lončarić, Sven; Bijnens, Bart (SpringerOpen, 2013)
    In this paper, we propose a novel approach for estimating image similarity. This measure is of importance in assessing image correspondence or image alignment and plays an important role in image registration. Currently, ...
  • Parés, Narcís, 1966-; Masri, Paul; van Wolferen, Gerard; Creed, Chris (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    This paper presents an adaptive physical environment that allows children with severe autism to successfully interact with/nmultimodal stimuli, giving them a sense of control of the interaction and, hence, providing them ...
  • Gouyon, Fabien; Widmer, Gerhard; Serra, Xavier; Flexer, Arthur (University of California Press, 2006)
    This article brings forward the question of which acoustic features are the most adequate for identifying beats computationally in acoustic music pieces. We consider many different features computed on consecutive short ...
  • Calabro, Finnegan; Soto-Faraco, Salvador, 1970-; Vaina, Lucia M. (Royal Society, 2011)
    In humans, as well as most animal species, perception of object motion is critical to successful interaction with the surrounding environment. Yet, as the observer also moves, the retinal projections of the various motion ...
  • Thalmeier, Dominik; Gómez, Vicenç; Kappen, Hilbert J. (IOS Press, 2016)
    The dynamical processes taking place on a network depend on its topology. Influencing the growth process of a network therefore has important implications on such dynamical processes. We formulate the problem of influencing ...
  • Chamorro-Servent, Judit; Bear, Laura; Duchateau, Josselin; Dallet, Corentin; Coudière, Yves; Dubois, Rémi (Computing in Cardiology, 2016)
    Meshing the heart and measurement surfaces can be time consuming, especially when dealing with complicated geometries or cardiac motion. To overcome this, a meshless method based on the method of fundamental solutions ...
