    • Adaptación de un método pseudo-espectral a condiciones de contorno no-libres 

      Ramos, Ivana Carola; Briozzo, Carlos Bruno (2014)
      Se presenta la adaptación a condiciones de contorno no libres de un método pseudo-espectral basado en transformada de Fourier compleja. El método se aplica a la integración numérica de las ecuaciones de Oberbeck-Boussinesq ...
    • Algebraic functions in quasiprimal algebras 

      Campercholi, Miguel; Vaggione, Diego (2014)
      A function is algebraic on an algebra A if it can be implicitly defined by a system of equations on A. In this note we give a semantic characterization for algebraic functions on quasiprimal algebras. This characterization ...
    • Anisotropy-based mechanism for zigzag striped patterns in magnetic thin films 

      Billoni, Orlando Vito; Bustingorry, S.; Barturen, M.; Milano, J.; Cannas, Sergio Alejandro (2014)
      In this work, we studied a two-dimensional ferromagnetic system using Monte Carlo simulations. Our model includes exchange and dipolar interactions, a cubic anisotropy term, and uniaxial out-of-plane and in-plane ones. ...
    • Axiomatizing bisimulation equivalences and metrics from probabilistic SOS rules 

      D'Argenio, Pedro Ruben; Gebler, Daniel; Lee, Matías David (2014)
      Probabilistic transition system specifications (PTSS) provide structural operational semantics for reactive probabilistic labeled transition systems. Bisimulation equivalences and bisimulation metrics are fundamental notions ...
    • The Brauer-Picard group of the representation category of finite supergroup algebras 

      Mombelli, Juan Martín (2014)
      We develop further the techniques presented in a previous article (M. Mombelli. Abh. Math. Semin. Univ. Hamb. 82 (2012), 173–192), to study bimodule categories over the representation categories of arbitrary finite-dimensional ...
    • Can we heal Chagas infection? 

      Vega Royero, Shirlene Patricia; Sibona, Gustavo Javier (2014)
      We present a model for the parasite-antibody dynamical competition between Trypanosoma rangeli and its antibodies during the acute phase of an infection in a mammal host. The model reproduces experimental data from murine ...
    • A certified extension of the Krivine machine for a call-by-name higher-order imperative language 

      Rodríguez, Leonardo Matías; Fridlender, Daniel Edgardo; Pagano, Miguel María (2014)
      In this paper we present a compiler that translates programs from an imperative higher-order language into a sequence of instructions for an abstract machine. We consider an extension of the Krivine machine for the ...
    • Characterization, definability and separation via saturated models 

      Areces, Carlos Eduardo; Carreiro, Facundo; Figueira, Santiago (2014)
      Three important results about the expressivity of a modal logic L are the Characterization Theorem (that identifies a modal logic L as a fragment of a better known logic), the Definability theorem (that provides conditions ...
    • Classification of integral modular categories of Frobenius–Perron dimension pq4 and p2q2 

      Bruillard, Paul; Galindo Martínez, César Neyit; Hong, Seung-Moon; Kashina, Yevgenia; Naidu, Deepak; Natale, Sonia Luján; Plavnik, Julia Yael; Rowell, Eric C. (2014)
      We classify integral modular categories of dimension pq4 and p2q2, where p and q are distinct primes. We show that such categories are always group-theoretical, except for categories of dimension 4q2. In these cases there ...
    • Clustering and decoherence of correlated spins under double quantum dynamics 

      Sánchez, Claudia M.; Acosta, Rodolfo Héctor; Pastawski, Horacio M.; Levstein, Patricia R.; Chattah, Ana K. (2014)
      We present an improved approach for the study of the evolution of spin correlations and decoherence in multiple quantum nuclear magnetic resonance experiments. The infinite system, constituted by the protons of a polycrystalline ...
    • The cohomology of filiform Lie algebras of maximal rank 

      Cagliero, Leandro Roberto; Tirao, Paulo (2014)
      We describe the structure of the cohomology of the filiform Lie algebras and as a module over their (2-dimensional) torus of derivations. Our approach relies on the fact that both filiform algebras have an ideal of codimension ...
    • Completeness in hybrid type theory 

      Areces, Carlos Eduardo; Blackburn, Patrick; Huertas, Antonia; Manzano, María (2014)
      We show that basic hybridization (adding nominals and @ operators) makes it possible to give straightforward Henkin-style completeness proofs even when the modal logic being hybridized is higher-order. The key ideas are ...
    • Conjugacy classes of p-cycles of type D in alternating groups 

      Fantino, Fernando Amado (2014-10)
      We classify the conjugacy classes of $p$-cycles of type D in alternating groups. This finishes the open cases in [AFGV]. Also we determine all the subracks of those conjugacy classes which are not of type D.
    • Constitutive hippocampal cholesterol loss underlies poor cognition in old rodents 

      Martín, Mauricio Gerardo; Ahmed, Tariq; Korovaichuk, Alejandra; Venero, César; Menchón, Silvia Adriana; Salas, Isabel; Munck, Sebastian; Herreras, Oscar; Balschun, Detlef; Dotti, Carlos Gerardo (2014)
      Cognitive decline is one of the many characteristics of aging. Reduced long-term potentiation (LTP) and long-term depression (LTD) are thought to be responsible for this decline, although the precise mechanisms underlying ...
