  • Dalmau, Víctor; Krokhin, Andrei; Larose, Benoit (Elsevier, 2008)
    The poset retraction problem for a poset P is whether a given poset Q containing P as a subposet admits a retraction onto P, that is, whether there is a homomorphism from Q onto P which fixes every element of P. We study ...

    In this chapter, we provide an overview of state-of-the-art algorithms for the automatic description of music audio signals, both from a low-level perspective (focusing on signal characteristics) and a more musical perspective ...

    Dialogic learning and interactive groups have proved to be a useful methodological approach applied/nin educational situations for lifelong adult learners. The principles of this approach stress the/nimportance of dialogue ...
  • Martí, Daniel; Deco, Gustavo; Mattia, Maurizio; Gigante, Guido; Del Giudice, Paolo (Public Library of Science (PLoS), 2008)
    The spike activity of cells in some cortical areas has been found to be correlated with reaction times and behavioral responses during two-choice decision tasks. These experimental findings have motivated the study of ...
  • Cuscó Martí, Ivon, 1973-; Campo Casanelles, Miguel del, 1966-; Vilardell Nogales, Mireia; González, Eva; Gener, Blanca; Galán, Enrique; Toledo, Laura; Pérez Jurado, Luis Alberto (BioMed Central, 2008)
    Background: Kabuki syndrome (KS) is a multiple congenital anomaly syndrome characterized by specific facial features, mild to moderate mental retardation, postnatal growth delay, skeletal abnormalities, and unusual ...
  • 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 ...
  • 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 ...
  • Tauste Campo, Adrià; 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 ...
  • Bauer-Mehren, Anna; Furlong, Laura I., 1971-; 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 ...
  • Harrow, Jennifer; Nagy, Alinda; Reymond, Alexandre; Alioto, Tyler; Patthy, Laszlo; Antonarakis, Stylianos E.; Guigó Serra, Roderic (BioMed Central, 2009)
    The vast majority of the biology of a newly sequenced genome is inferred from the set of encoded proteins. Predicting this set is therefore invariably the first step after the completion of the genome DNA sequence. Here ...
  • Girirajan, Santhosh; Chen, Lin; Graves, Tina A.; 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-; Kidd, Jeffrey M.; Ventura, Mario; Graves, Tina A.; Cheng, Ze; Hillier, LeDeana W.; Jiang, Zhaoshi; Baker, Carl; Malfavon-Borja, Ray; Fulton, Lucinda; 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 ...
  • Marquès i Bonet, Tomàs, 1975-; Girirajan, Santhosh; 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 ...
  • Bauer-Mehren, Anna; Furlong, Laura I., 1971-; 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 ...
  • Macía, Javier; Widder, Stefanie; Solé Vicente, Ricard, 1962- (BioMed Central, 2009)

  • Maestre Gómez, Esteban; Ramírez, Rafael,1966- (IOS Press, 2009)
    We present a machine learning approach to modeling bowing control parameter/ncontours in violin performance. Using accurate sensing techniques/nwe obtain relevant timbre-related bowing control parameters such as bow/ntransversal ...
