  • Deco, Gustavo; McIntosh, Anthony R.; Shen, Kelly; Hutchison, R. Matthew; Menon, Ravi S.; Everling, Stefan; Hagmann, Patric; Jirsa, Viktor K. (Society for Neuroscience, 2014)
    The complex network dynamics that arise from the interaction of the brain’s structural and functional architectures give rise to mental function. Theoretical models demonstrate that the structure–function relation is ...
  • Tulino, Antonia M.; Lozano Solsona, Angel; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    This paper applies random matrix theory to obtain analytical characterizations of the capacity of correlated multiantenna channels. The analysis is not restricted to the popular separable correlation model, but rather it ...
  • Liu, Dan; Hu, Kai; Niemann, Markus; Herrmann, Sebastian; Cikes, Maja; Stork, Stefan; Beer, Meinrad; Gaudron, Daniel; Morbach, Caroline; Knop, Stefan; Geissinger, Eva; Ertl, George; Bijnens, Bart; Weidemann, Frank (Public Library of Science, 2013)
    Objectives: The aim of this study was to explore the left ventricular (LV) deformation changes and the potential impact of deformation on outcome in patients with proven light-chain (AL) amyloidosis and LV hypertrophy. ...
  • Spa Carvajal, Carlos; Garriga, Adan; Escolano, José (Elsevier, 2009)
    The Pseudo-Spectral Time Domain (PSTD) method is an alternative time-marching method to classical leapfrog finite difference schemes in the simulation of wave-like propagating phenomena. It is based on the fundamentals ...
  • Klimm, Florian; Borge-Holthoefer, Javier; Wessel, Niels; Kurths, Jürgen; Zamora-López, Gorka (IOP Publishing, 2014)
    The analysis of complex networks is devoted to the statistical characterization of the topology of graphs at different scales of organization in order to understand their functionality. While the modular structure of ...
  • Sebastián Gallés, Núria; Soley, Gaye (Wiley, 2015)
    Infants show attentional biases for certain individuals over others based on various cues. However, the role of these biases in shaping infants' preferences and learning is not clear. This study asked whether infants' ...
  • Parés, Narcís, 1966-; Parés, Roc, 1968- (MIT Press, 2001)
    Virtual reality application design is usually guided by a content-driven strategy, which gives priority to the application's content and context. In this paper, we shall describe and study a novel strategy in VR application ...
  • Lozano Solsona, Angel; Biglieri, Ezio; Alrajeh, Nabil (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    A standard paradigm for the allocation of wireless resources in communication demands symmetry, that is, all users are assumed to be on equal footing and hence get equal shares of the system’s communication capabilities. ...
  • Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    Expressions relating spectral efficiency, power, and Doppler spectrum, are derived for Rayleigh-faded wireless channels with Gaussian signal transmission. No side information on the state of the channel is assumed at the ...
  • Koduri, Gopala Krishna; Ishwar, Vignesh; Serrà Julià, Joan; Serra, Xavier (Taylor & Francis (Routledge), 2014)
    Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of a rga and key to the musical expression of the artist. Describing intonation is of importance to several ...
  • Guimerà, Anton; Illa, Xavi; Traver, Estefania; Marchán, Sandra; Herrero, Carmen; Maldonado, Miguel José; Lagunas, Carmen; Ivorra Cano, Antoni, 1974-; Villa, Rosa (IOP Publishing Ltd, 2013)
    The cornea is a transparent structure composed of three layers: the epithelium, the stroma and the endothelium. To maintain its ransparency the stroma remains in a constant state of dehydration. Consequently, any ion flow ...
  • Becerra-Fajardo, Laura; Ivorra Cano, Antoni, 1974- (Public Library of Science (PLoS), 2015)
    Electrical stimulation is used in order to restore nerve mediated functions in patients with neurological disorders, but its applicability is constrained by the invasiveness of the systems required to perform it. As an ...
  • Facciolo Furlan, Gabriele; Almansa, Andrés; Aujol, Jean-François; Caselles, Vicente (SIAM (Society for Industrial and Applied Mathematics), 2009)
    We propose a restoration algorithm for band limited images that considers irregular (perturbed) sampling, denoising, and deconvolution. We explore the application of a family of regularizers that allow to control the ...
  • Sánchez-Velázquez, Joan; Castellví, Quim; Villanueva, Alberto; Quesada, Rita; Pañella-Vilamú, Clara; Cáceres, Mario; Dorcaratto, Dimitri; Andaluz, Anna; Moll, Xavier; Trujillo Guillén, Macarena; Burdío, José Miguel; Berjano, Enrique J.; Grande Posa, Luís; Ivorra Cano, Antoni, 1974-; Burdío, Fernando (Nature Publishing Group, 2016)
    Irreversible electroporation is a fast-growing liver ablation technique. Although safety has been well documented in small ablations, our aim is to assess its safety and feasibility when a large portion of liver is ablated. ...
  • Dohler, Mischa; Heath, R. W., Jr.; Lozano Solsona, Angel; Papadias, Constantinos B.; Valenzuela, R. A. (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    This article originates from a panel with the above title, held at IEEE VTC Spring 2009, in which the authors took part. The enthusiastic response it received prompted us to discuss for a wider audience whether research ...
  • Brignani, Debora; Ruzzoli, Manuela; Mauri, Piercarlo; Miniussi, Carlo (Public Library of Science, 2013)
    Transcranial alternating current stimulation (tACS) is a promising tool for modulating brain oscillations, as well as a possible therapeutic intervention. However, the lack of conclusive evidence on whether tACS is able ...
  • Papazachariadis, Odysseas; Dante, Vittorio; Verschure, Paul F. M. J.; Del Giudice, Paolo; Ferraina, Stefano (Public Library of Science, 2014)
    Recently, neuromodulation techniques based on the use of repetitive transcranial magnetic stimulation (rTMS) have been proposed as a non-invasive and efficient method to induce in vivo long-term potentiation (LTP)-like ...
  • Hernández Leo, Davinia; Romeo, Lauren Michele; Carralero, Miguel A.; Chacón Pérez, Jonathan, 1986-; Carrió, Mar; Moreno, Pau; Blat, Josep (Elsevier, 2011)
    Two important challenges that teachers are currently facing are the sharing and the collaborative authoring of their learning design solutions, such as didactical units and learning materials. On the one hand, there are ...
