  • Chung, Seong Taek; Lozano Solsona, Angel; Huang, Howard C.; Sutivong, Arak; Cioffi, John M. (Hindawi, 2004)
    This paper presents an extension of the vertical Bell Laboratories Layered Space-Time (V-BLAST) architecture in which the closed-loop multiple-input multiple-output (MIMO) capacity can be approached with conventional scalar ...
  • Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    The purpose of this paper is to examine some of the models commonly used to represent/nfading as well as the information-theoretic metrics most commonly used to evaluate performance/nover those models. We raise the question ...
  • Vessel, Edward A; Starr, Gabrielle; Rubin, Nava (Frontiers Media, 2013)
    In a task of rating images of artworks in an fMRI scanner, regions in the medial prefrontal cortex that are known to be part of the default mode network (DMN) were positively activated on the highest-rated trials. This is ...
  • Srinivasamurthy, Ajay; Holzapfel, Andre; Ganguli, Kaustuv Kanti; Serra, Xavier (Frontiers, 2017)
    This article provides insights into aspects of tempo and rhythmic elaboration in Hindustani music, based on a study of a large corpus of recorded performances. Typical tempo developments and stress patterns within a ...
  • Rudenick, Paula A.; Bijnens, Bart; Segers, Patrick F.; García-Dorado, David; Evangelista, Arturo (Public Library of Science (PLoS), 2015)
    Descending aortic dissection (DAD) is associated with high morbidity and mortality rates. Aortic wall stiffness is a variable often altered in DAD patients and potentially involved in long-term outcome. However, its relevance ...
  • Schmitz, Judith, 1984-; Díaz Menéndez, Begoña, 1979-; Sebastián Gallés, Núria (Taylor & Francis (Routledge), 2016)
    Previous studies showed that manipulating the speech production system influenced speech perception. This influence was mediated by task difficulty, listening conditions, and attention. In the present study we investigated ...
  • Manathunga, Kalpani; Hernández Leo, Davinia (Wiley, 2017)
    Collaborative Learning Flow Patterns (CLFPs) formulate best practices for the orchestration of activity sequences and collaboration mechanisms that can elicit fruitful social interactions. Mobile technology features offer ...
  • García Cañadilla, Patricia, 1985-; Gonzalez-Tendero, Anna; Iruretagoyena, Igor; Crispi Brillas, Fàtima; Torre, Iratxe; Amat-Roldán, Iván; Bijnens, Bart; Gratacós Solsona, Eduard (Society of Photo Optical Instrumentation Engineers (SPIE), 2014)
    Automatic quantification of cardiac muscle properties in tissue sections might provide important information related to different types of diseases. Second harmonic generation (SHG) imaging provides a stain-free microscopy ...
  • Bogunovic, Hrvoje; Pozo Soler, José Ma. (José María); Villa-Uriol, Maria-Cruz; Majoie, Charles B. L. M.; van den Berg, Rene; Gratama van Andel, Hugo A. F.; Macho, Juan M.; Blasco, Jordi; San Román, Luis; Frangi Caregnato, Alejandro (American Association of Physicists in Medicine (AAPM), 2010)
    Purpose: To evaluate the suitability of an improved version of an automatic segmentation method based on geodesic active regions (GAR) for segmenting cerebral vasculature with aneurysms from 3D X-ray reconstruc-/ntion ...
  • Farrús, Mireia; Costa-jussà, Marta R. (Athabasca University Press, 2013)
    Assessment in education allows for obtaining, organizing, and presenting information about how much and how well the student is learning. The current paper aims at analysing and discussing some of the most state-of-the-art ...
  • Igual, Laura; Preciozzi, Javier; Garrido, Luís; Almansa, Andrés; Caselles, Vicente; Rougé, Bernard (AIMS American Institute of Mathematical Sciences, 2007)
    In this work we propose a new automatic methodology for computing accurate digital elevation models (DEMs) in urban environments from low baseline stereo pairs that shall be available in the future from a new kind of earth ...
  • Farrús, Mireia; Wagner, Michael; Erro, Daniel; Hernando, Javier (Equinox Publishing, 2010)
    Voices can be deliberately disguised by means of human imitation or voice conversion. The question arises as to what extent they can be modified by using either of both methods. In the current paper, a set of speaker ...
