  • Biglieri, Ezio (National Institute of Information and Communications Technology (NICT), 2008)
    We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number of active interferers. Using a statistical-physics approach, we compute the single-user channel ...
  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (European Association for Signal Processing (EURASIP), 2008)
    Silver Code (SilC) was originally discovered in [1–4] for 2×2 multiple-input multiple-output (MIMO) transmission. It has non-vanishing minimum determinant 1/7, slightly lower than Golden code, but is fast-decodable, i.e., ...
  • Biglieri, Ezio; Grossi, Emanuele; Lops, Marco; Tauste Campo, Adrià (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We study the minimum mean square error (MMSE) and the multiuser efficiency η of large dynamic multiple access communication systems in which optimal multiuser detection is performed at the receiver as the number and the ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    In this paper, we introduce a pilot-aided multipath channel estimator for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. Typical estimation algorithms assume the number of ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (European Association for Signal Processing (EURASIP), 2008)
    In multiuser detection, the set of users active at any time may be unknown to the receiver. In these conditions, optimum reception consists of detecting simultaneously the set of active users and their data, problem that ...
  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We focus on full-rate, fast-decodable space–time block codes (STBCs) for 2 x 2 and 4 x 2 multiple-input multiple-output (MIMO) transmission. We first derive conditions and design criteria for reduced-complexity maximum-likelihood ...
  • Marquès i Bonet, Tomàs, 1975-; Girirajan, Santosh; Eichler, Evan E. (Elsevier, 2009)
    Duplicated sequences are substrates for the emergence of new genes and are an important source of genetic instability associated with rare and common diseases. Analyses of primate genomes have shown an increase in the ...
  • 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 ...
  • Girirajan, Santosh; Chen, Lin; Graves, Tina; Marquès i Bonet, Tomàs, 1975-; Ventura, Mario; Fronick, Catrina; Fulton, Lucinda; Rocchi, Mariano; Fulton, Robert S.; Wilson, Richard K.; Mardis, Elaine R.; Eichler, Evan E. (Cold Spring Harbor Laboratory Press-CSHL Press, 2009)
    The gibbon genome exhibits extensive karyotypic diversity with an increased rate of chromosomal rearrangements during evolution. In an effort to understand the mechanistic origin and implications of these rearrangement ...
  • Marquès i Bonet, Tomàs, 1975-; Ryder, Oliver A.; Eichler, Evan E. (Annual Reviews Inc, 2009)
    We summarize the progress in whole-genome sequencing and analyses of primate genomes. These emerging genome datasets have broadened our understanding of primate genome evolution revealing unexpected and complex patterns ...
  • Maestre Gómez, Esteban; Ramírez, Rafael; Kersten, Stefan; Serra, Xavier (MIT Press, 2009)
    Here we describe an approach to the expressive synthesis of jazz saxophone melodies that reuses audio recordings and carefully concatenates note samples. The aim is to generate an expressive audio sequence from the analysis ...
  • Bauer-Mehren, Anna; Furlong, Laura I.; Sanz, Ferran (Nature Publishing Group, 2009)
    In past years, comprehensive representations of cell signalling pathways have been developed by manual curation from literature, which requires huge effort and would benefit from information stored in databases and from ...
  • Bauer-Mehren, Anna; Furlong, Laura I.; Rautschka, Michael; Sanz, Ferran (BioMed Central, 2009)
    Background: Single nucleotide polymorphisms (SNPs) are the most frequent type of sequence variation between individuals, and represent a promising tool for finding genetic determinants of complex diseases and understanding ...
  • Singh, Pankai K.; Marzo, Alberto; Coley, Stuart C.; Berti, Guntram; Bijlenga, Philippe; Lawford, Patricia V.; Villa-Uriol, Maria-Cruz; Rufenacht, Daniel A.; McCormack, Keith M.; Frangi Caregnato, Alejandro; Patel, Umang J.; Hose, D. Rodney (Hindawi, 2009)
    Objective: The importance of hemodynamics in the etiopathogenesis of intracranial aneurysms (IAs) is widely accepted. Computational fluid dynamics (CFD) is being used increasingly for hemodynamic predictions. However, ...
  • Maestre Gómez, Esteban; Ramírez, Rafael (IOS Press, 2009)
    We present a machine learning approach to modeling bowing control parameter contours in violin performance. Using accurate sensing techniques we obtain relevant timbre-related bowing control parameters such as bow transversal ...
  • 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 ...
  • Bekpen, Cemalettin; Marquès i Bonet, Tomàs, 1975-; Alkan, Can; Antonacci, Francesca; Leogrande, Maria Bruna; Ventura, Mario; Kidd, Jeffrey M.; Siswara, Priscillia; Howard, Jonathan C.; Eichler, Evan E. (Public Library of Science (PLoS), 2009)
    Immunity-related GTPases (IRG) play an important role in defense against intracellular pathogens. One member of this gene family in humans, IRGM, has been recently implicated as a risk factor for Crohn's disease. We analyzed ...
  • Marquès i Bonet, Tomàs, 1975-; Kidd, Jeffrey M.; Ventura, Mario; Graves, Tina A.; Cheng, Ze; Hillier, LaDeana W.; Jiang, Zhaoshi; Baker, Carl; Malfavon-Borja, Ray; Fulton, Lucinda A.; Alkan, Can; Aksay, Gozde; Girirajan, Santhosh; Siswara, Priscillia; Chen, Lin; Cardone, Maria Francesca; Navarro i Cuartiellas, Arcadi, 1969-; Mardis, Elaine R.; Wilson, Richard K.; Eichler, Evan E. (Nature Publishing Group, 2009)
    It is generally accepted that the extent of phenotypic change between human and great apes is dissonant with the rate of molecular change. Between these two groups, proteins are virtually identical, cytogenetically there ...
  • Maestre Gómez, Esteban (International Computer Music Association, 2009)
    We present a framework for modeling right-hand gestures in bowed-string instrument playing, applied to violin. Nearly non-intrusive sensing techniques allow for accurate acquisition of relevant timbre-related bowing gesture ...
