      Valente, Mauro Andrés; Malano, Francisco Mauricio; Pérez, Pedro Antonio (2014)
      Nuclear medicine clinical practices for neoplasic disease diagnose and treatment are based on the incorporation of α, β and γ radiotracers and radiopharmaceuticals, which might be associated with potential damage. Thus, ...
    • Interpreting natural language instructions using language, vision and behavior 

      Benotti, Luciana; Lau, Tessa; Villalba, Martín Federico (2010)
      We define the problem of automatic instruction interpretation as follows. Given a natural language instruc- tion, can we automatically predict what an instruction follower, such as a robot, should do in the environment to ...
    • Intrinsic angular momentum for radiating spacetimes which agrees with the Komar integral in the axisymmetric case 

      Gallo, Emanuel; Moreschi, Osvaldo Mario (2014)
      Here, we present a new definition of intrinsic angular momentum at future null infinity, based on the charge-integral approach. This definition is suitable for the general case of radiating spacetimes without symmetries, ...

      Araújo Velasque, Luciana; Stariolo, Daniel Adrián; Billoni, Orlando Vito (2014)
      We present a theoretical study aimed at elucidating the origin of the inverse symmetry-breaking transition observed in ultrathin magnetic films with perpendicular anisotropy. We study the behavior of the dipolar frustrated ...
    • Invertible bimodule categories over the representation category of a Hopf algebra 

      Femić, Bojana; Mejía Castaño, Adriana; Mombelli, Juan Martín (2014-02-12)
      For any finite-dimensional Hopf algebra H we construct a group homomorphism BiGal (H) → BrPic(Rep(H)), from the group of equivalence classes of H-biGalois objects to the group of equivalence classes of invertible exact ...
    • Irradiated graphene as a tunable Floquet topological insulator 

      Usaj, Gonzalo; Pérez Piskunow, Pablo Matías; Foa Torres, Luis Eduardo Francisco; Balseiro, Carlos A. (2014)
      In the presence of a circularly polarized mid-infrared radiation graphene develops dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator. Here, we analyze how topologically protected edge ...
    • Isomorphism and disorder in o-chlorohalobenzenes studied by NQR 

      Pérez, Silvina C.; Wolfenson, Alberto; Zuriaga, Mariano (2014)
      In this work we present experimental results that allow to characterize different solid modifications found in o-chlorohalobenzenes. Three disordered phases have been found in o-chlorobromobenzene. The stable phase at ...
    • Kerma and photons absorbed-dose from Ir-192 HDR seeds 

      Chesta, Miguel Ángel; Poma, Ana Lucía; Mc Donnell, Dionisio José (2014)
      Precise calculations of absorbed dose (AD) are a difficult task involving physical phenomena such as emission, transport, and absorption of radiation. We used the Monte Carlo method to calculate Kerma as well as AD in water ...
    • Landau-Zener and Rabi oscillations in the spin-dependent conductance 

      Fernández Alcázar, Lucas Jonatan; Pastawski, Horacio Miguel (2014)
      We describe the spin-dependent quantum conductance in a wire where a magnetic field is spatially modulated. The changes in direction and intensity of the magnetic field acts as a perturbation that mixes spin projections. ...
    • Lifting via cocycle deformation 

      Andruskiewitsch, Nicolás; Angiono, Iván Ezequiel; García Iglesias, Agustín; Masuoka, Akira; Vay, Cristian Damián (2014)
      We develop a strategy to compute all liftings of a Nichols algebra over a finite dimensional cosemisimple Hopf algebra. We produce them as cocycle deformations of the bosonization of these two. In parallel, we study the ...
    • Lightning in Western Patagonia 

      Garreaud, René D.; Nicora, M. Gabriela; Bürgesser, Rodrigo E.; Ávila, Eldo E. (2014)
      On the basis of 8 years (2005-2012) of stroke data from the World Wide Lightning Location Network we describe the spatial distribution and temporal variability of lightning activity over Western Patagonia. This region ...
    • Magnetite NPs@C with highly-efficient peroxidase-like catalytic activity as an improved biosensing strategy for selective glucose detection 

      Arana, Mercedes; Tettamanti, Cecilia Soledad; Bercoff, Paula Gabriela; Rodríguez, Marcela Cecilia (2014)
      This work reports the novel application of carbon-coated magnetite nanoparticles (mNPs@C) as catalytic nanomaterial included in a composite electrode material (mNPs@C/CPE) taking advantages of their intrinsic peroxidase-like ...
    • Magnitude modelling of HRTF using principal component analysis applied to complex values 

      Ramos, Oscar Alberto; Tommasini, Fabián Carlos (2014)
      Principal components analysis (PCA) is frequently used for modelling the magnitude of the head related transfer functions (HRTFs). Assuming that the HRTFs are minimum phase systems, the phase is obtained from the Hilbert ...
    • Memory and long-range correlations in chess games 

      Schaigorodsky, Ana L.; Perotti, Juan I.; Billoni, Orlando V. (2014)
      In this paper we report the existence of long-range memory in the opening moves of a chronologically ordered set of chess games using an extensive chess database. We used two mapping rules to build discrete time series and ...
    • Methods and results of a search for gravitational waves associated with gamma-ray bursts using the GEO 600, LIGO, and Virgo detectors 

      LIGO Scientific Collaboration; Virgo Collaboration; Aasi, J.; Maglione, C.; Reula, O.; Dominguez, E.; Ortega, W.; Schilman, M.; Wolovick, N. (2014)
      In this paper we report on a search for short-duration gravitational wave bursts in the frequency range 64 Hz–1792 Hz associated with gamma-ray bursts (GRBs), using data from GEO 600 and one of the LIGO or Virgo detectors. ...
    • Mixing Bandt-Pompe and Lempel-Ziv approaches : another way to analyze the complexity of continuous-state sequences 

      Zozor, Steeve; Mateos, Diego M.; Lamberti, Pedro W. (2014)
      In this paper, we propose to mix the approach underlying Bandt-Pompe permutation entropy with Lempel-Ziv complexity, to design what we call Lempel-Ziv permutation complexity. The principle consists of two steps: (i) ...

      Daza Caro, Yudy Carolina; Tauro, Carolina Beatriz; Tamarit, Francisco Antonio; Gleiser, Pablo Martín (2014)
      We propose a model for the formation of patterns in the visual cortex. The dynamical units of the model are Kuramoto phase oscillators that interact through a complex network structure embedded in two dimensions. In this ...
