  • 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 ...
  • Persico, Donatella; Pozzi, Francesca; Anastopoulou, Stamatina; Conole, Grainne; Craft, Brock; Dimitriadis, Yannis; Hernández Leo, Davinia; Kali, Yael; Mor, Yishay; Pérez Sanagustín, Maria del Mar; Walmsley, Helen (Co-Action Publishing, 2013)
    This paper presents and compares a variety of approaches that have been developed to guide the decision-making process in learning design. Together with the companion Learning Design Rashomon II (Prieto et al., 2013), ...
  • Malinverni, Laura; Parés, Narcís, 1966- (International Forum of Educational Technology & Society, 2014)
    Over the past ten years several learning environments based on novel interaction modalities have been developed. Within this field, Full-body Interaction Learning Environments open promising possibilities given their ...
  • Girardin, Fabien; Dal Fiore, Filippo; Ratti, Carlo; Blat, Josep (Taylor & Francis (Routledge), 2008)
    In recent years, the large deployment of mobile devices has led to a massive increase in the volume of records of where people have been and when they were there. The analysis of these spatio-temporal data can supply ...
  • Fedorov, Vadim; Arias, Pablo; Sadek, Rida; Facciolo Furlan, Gabriele; Ballester, Coloma (SIAM (Society for Industrial and Applied Mathematics), 2015)
    In this paper we study the problem of comparing two patches of images defined on Riemannian manifolds which in turn can be defined by each image domain with a suitable metric depending on the image. For that we single ...
  • Sentürk, Sertan; Holzapfel, Andre; Serra, Xavier (Taylor & Francis (Routledge), 2014)
    The most relevant representations of music are notations and audio recordings, each of which emphasizes a particular perspective and promotes different approximations in the analysis and understanding of music. Linking ...
  • Ledberg, Anders; Robbe, David (Public Library of Science, 2011)
    The hippocampal theta rhythm is required for accurate navigation and spatial memory but its relation to the dynamics of locomotion is poorly understood. We used miniature accelerometers to quantify with high temporal and ...
  • Boutros, Joseph Jean; Guillén i Fàbregas, Albert; Biglieri, Ezio; Zémor, Gilles (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    We design powerful low-density parity-check (LDPC) codes with iterative decoding for the block-fading channel. We first study the case of maximum-likelihood decoding, and show that the design criterion is rather straightforward. ...
  • Pazó, Diego; Montbrió, Ernest (American Physical Society, 2014)
    Large communities of biological oscillators show a prevalent tendency to self-organize in time. This cooperative phenomenon inspired Winfree to formulate a mathematical model that originated the theory of macroscopic ...
  • Papiotis, Panagiotis, 1985-; Marchini, Marco, 1984-; Pérez Carrillo, Alfonso Antonio, 1977-; Maestre Gómez, Esteban (Frontiers Media, 2014)
    In a musical ensemble such as a string quartet, the musicians interact and influence each other's actions in several aspects of the performance simultaneously in order to achieve a common aesthetic goal. In this article, ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2005)
    We describe the version of the GPT planner to be used in the planning competition. This version, called mGPT, solves mdps specified in the ppddl language by extracting and using different classes of lower bounds, along ...
  • Zhang, Chong; Villa-Uriol, Maria-Cruz; De Craene, Mathieu; Pozo Soler, José Ma. (José María); Frangi Caregnato, Alejandro (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    This paper presents a technique to estimate and model patient-specific pulsatility of cerebral aneurysms over one cardiac cycle, using 3D rotational X-ray angiography (3DRA) acquisitions. Aneurysm pulsation is modeled as ...
  • Pastukhov, Alexander; García Rodríguez, Pedro Ernesto; Haenicke, Joachim; Guillamon i Grabolosa, Antoni; Deco, Gustavo; Braun, Jochen (Frontiers Media, 2013)
    We report that multi-stable perception operates in a consistent, dynamical regime, balancing the conflicting goals of stability and sensitivity. When a multi-stable visual display is viewed continuously, its phenomenal ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The problem of jointly estimating the number, the identities, and the data of active users in a time-varying multiuser environment was examined in a companion paper (IEEE Trans. Information Theory, vol. 53, no. 9, September ...
  • Rusek, Fredrik; Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    We present a method to compute, quickly and efficiently, the mutual information achieved by an IID (independent identically distributed) complex Gaussian signal on a block Rayleigh-faded channel without side information ...
  • Masquelier, Timothée; Deco, Gustavo (Public Library of Science (PLoS), 2013)
    In the brain, synchronization among cells of an assembly is a common phenomenon, and thought to be functionally relevant. Here we used an in vitro experimental model of cell assemblies, cortical cultures, combined with ...
  • Arsiwalla, Xerxes D.; Zucca, Riccardo; Betella, Alberto; Martínez, Enrique, 1961-; Dalmazzo, David; Omedas, Pedro; Deco, Gustavo; Verschure, Paul F. M. J. (Frontiers Media, 2015)
    BrainX3 is a large-scale simulation of human brain activity with real-time interaction, rendered in 3D in a virtual reality environment, which combines computational power with human intuition for the exploration and ...
  • Barrós Loscertales, Alfonso; Ventura Campos, Noelia; Visser, Maya; Alsius, Agnès; Pallier, Christophe; Ávila Rivera, César; Soto-Faraco, Salvador, 1970- (Elsevier, 2013)
    Neuroimaging studies of audiovisual speech processing have exclusively addressed listeners’ native language (L1). Yet, several behavioural studies now show that AV processing plays an important role in non-native (L2) ...
  • Deco, Gustavo; Hugues, Etienne (Public Library of Science, 2016)
    It is well established that the variability of the neural activity across trials, as measured by the Fano factor, is elevated. This fact poses limits on information encoding by the neural activity. However, a series of ...
  • Van Hartevelt, Tim J.; Cabral, Joana R. B.; Deco, Gustavo; Møller, Arne; Green, Alex L.; Aziz, Tipu Z.; Kringelbach, Morten L. (Public Library of Science (PLoS), 2014)
    Background: Positive clinical outcomes are now well established for deep brain stimulation, but little is known about the effects of long-term deep brain stimulation on brain structural and functional connectivity. Here, ...
