  • Ivorra Cano, Antoni, 1974-; González-Sosa, Jarold; Ruiz-Vargas, Albert; Arias, Guillem (Elsevier, 2014)
    Pulsed Electric Field technologies have captured the attention of researchers on food/npasteurization because of their non-thermal inactivation mechanism, which results in fresh-like/nproducts. Nevertheless, high voltage ...
  • De Massari, Daniele; Pacheco, Daniel; Malekshahi, Rahim; Betella, Alberto; Verschure, Paul F. M. J.; Birbaumer, Niels; Caria, Andrea (2014)
    The combination of Brain-Computer Interface (BCI) technology, allowing online monitoring and decoding of brain activity, with virtual and mixed reality (MR) systems may help to shape and guide implicit and explicit learning ...
  • Chamorro-Servent, Judit; Aguirre, Juan; Ripoll, Jorge; Vaquero, Juan J.; Desco, Manuel (Optical Society of America (OSA), 2011)
    When dealing with ill-posed problems such as fluorescence diffuse optical tomography (fDOT) the choice of the regularization parameter is extremely important for computing a reliable reconstruction. Several automatic methods ...
  • Boccardi, Federico; Heath, R. W., Jr.; Lozano Solsona, Angel; Marzetta, Thomas L.; Popovski, Petar (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    New research directions will lead to fundamental changes in the design of future 5th generation (5G)/ncellular networks. This paper describes five technologies that could lead to both architectural and/ncomponent disruptive ...
  • Abascal, Juan F.P.J; Chamorro-Servent, Judit; Aguirre, Juan; Arridge, Simon; Correia, Teresa; Ripoll, Jorge; Vaquero, Juan J.; Desco, Manuel (American Association of Physicists in Medicine, 2011)
    Purpose: Standard image reconstruction methods for fluorescence Diffuse Optical Tomography (fDOT) generally make use of L2-regularization. A better choice is to replace the L2 by a total variation functional that effectively ...
  • Pañella-Vilamú, Clara; Castellví Fernández, Quim; Moll, Xavier; Quesada, Rita; Villanueva, Alberto; Iglesias, Mar; Naranjo, Dolores; Sánchez-Velázquez, Patricia; Andaluz, Anna; Grande, Luís; Ivorra Cano, Antoni, 1974-; Burdío Pinilla, Fernando (De Gruyter Open, 2017)
    Background. Spread hepatic tumours are not suitable for treatment either by surgery or conventional ablation methods. The aim of this study was to evaluate feasibility and safety of selectively increasing the healthy ...
  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (IGI Global, 2013)
    Collaborative tagging has emerged as a common solution for labelling and organising online digital content. However, collaborative tagging systems typically suffer from a number of issues such as tag scarcity or ambiguous ...
  • Romero Rivas, Carlos, 1986-; Martin, Clara D.; Costa, Albert, 1970- (Elsevier, 2016)
    Listeners are able to anticipate upcoming words during sentence comprehension, and, as a result, they also pre-activate semantically related words. In the present study, we aim at exploring whether these anticipatory ...
  • Castañer Balcells, Marta; Camerino Foguet, Oleguer; Parés, Narcís, 1966-; Landry, Pascal (Elsevier, 2011)
    We present an exertion interface called the Interactive Slide (Soler, Ferrer, Parés, 2009), a large inflatable slide augmented with virtual reality technology that offers the possibility to children to move freely in a ...
  • Hernández Leo, Davinia; Bote-Lorenzo, Miguel L.; Asensio-Pérez, Juan I.; Gómez-Sánchez, Eduardo; Villasclaras-Fernández, Eloy D.; Jorrín-Abellán, Iván M.; Dimitriadis, Yannis (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    This paper describes a Computer-Supported Collaborative Learning (CSCL) case study in engineering education carried out within the context of a network management course. The case study shows that the use of two computing ...
  • Bertalmío, Marcelo (Frontiers Media, 2014)
    There are many ways in which the human visual system works to reduce the inherent redundancy of the visual information in natural scenes, coding it in an efficient way. The non-linear response curves of photoreceptors and ...
  • Martin, Clara D.; García, Xavier, 1967-; Breton, Audrey; Thierry, Guillaume; Costa, Albert, 1970- (Frontiers Media, 2014)
    Do the integration of semantic information and that of world knowledge occur simultaneously or in sequence during sentence processing? To address this question, we investigated event-related brain potentials elicited by ...
  • Montbrió, Ernest, 1974-; Pazó, Diego (American Physical Society, 2016)
    Collective chaos is shown to emerge, via a period-doubling cascade, from quasiperiodic partial synchronization in a population of identical inhibitory neurons with delayed global coupling. This system is thoroughly ...
  • Mungara, Ratheesh K.; Thibault, Ilaria; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This paper characterizes, through a stochastic geometry analysis, the increase in spectral efficiency that full-duplex transmission brings about in wireless networks. While, on isolated links, full-duplex promises a doubling ...
  • Zamora-López, Gorka; Cheng, Yuan; Deco, Gustavo; Kringelbach, Morten L.; Zhou, Changsong (Nature Publishing Group, 2016)
    The large-scale structural ingredients of the brain and neural connectomes have been identified in recent years. These are, similar to the features found in many other real networks: the arrangement of brain regions into ...
  • Lozano Solsona, Angel; Heath, R. W., Jr.; Andrews, Jeffrey G. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Cooperation is viewed as a key ingredient for interference/nmanagement in wireless networks. This paper shows that/ncooperation has fundamental limitations. First, it is established/nthat in systems that rely on pilot-assisted ...
  • Farrús, Mireia (Equinox Publishing, 2009)
    Automatic speaker recognition is the use of a machine to identify an individual from a spoken sentence. Recently, this technology has been increasingly used in applications such as access control, transaction authentication, ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
