Interpreting natural language instructions using language, vision and behavior
(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 ... -
Axiomatizing bisimulation equivalences and metrics from probabilistic SOS rules
(2014)Probabilistic transition system specifications (PTSS) provide structural operational semantics for reactive probabilistic labeled transition systems. Bisimulation equivalences and bisimulation metrics are fundamental notions ... -
A certified extension of the Krivine machine for a call-by-name higher-order imperative language
(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 ... -
On nonsingular two-step nilpotent Lie algebras
(2014)A 2-step nilpotent Lie algebra n is called non-singular if ad X : n → [n, n] is onto for any X /∈ [n, n]. We explore non-singular algebras in several directions, including the classification problem (isomorphism invariants), ... -
On homogeneous Ricci solitons
(2014)We study the evolution of homogeneous Ricci solitons under the bracket flow, a dynamical system on the space Hq,n ⊂ Λ2g∗ ⊗ g of all homogeneous spaces of dimension n with a q-dimensional isotropy, which is equivalent to ... -
Mixing Bandt-Pompe and Lempel-Ziv approaches : another way to analyze the complexity of continuous-state sequences
(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) ... -
Lifting via cocycle deformation
(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 ... -
Classification of integral modular categories of Frobenius–Perron dimension pq4 and p2q2
(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 ... -
Self-avoiding walks on a bilayer Bethe lattice
(2014)We propose and study a model of polymer chains in a bilayer. Each chain is confined in one of the layers and polymer bonds on first neighbor edges in different layers interact. We also define and comment results for a ... -
Tailoring optical fields emitted by nanometric sources
(2014)In this work we study a simple way of controlling the emitted fields of sub-wavelength nanometric sources. The system studied consists of arrays of nanoparticles (NPs) embedded in optical active media. The key concept is ... -
On the linear stability of the extreme Kerr black hole under axially symmetric perturbations
(2014)We prove that for axially symmetric linear gravitational perturbations of the extreme Kerr black hole, there exists a positive definite and conserved energy. This provides a basic criteria for linear stability in axial ... -
Algebraic functions in quasiprimal algebras
(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
(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. ... -
Clustering and decoherence of correlated spins under double quantum dynamics
(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 ... -
Expression of VEGF-A, HIF-1 A, CD34 and Ki67 in clear cell renal cell carcinomas and their relationship with conventional prognostic markers
(2014)El carcinoma renal de células claras es la variante más frecuente de carcinoma renal. En los últimos años, la atención se ha enfocado en la expresión de factores angiogénicos por estos tumores, lo que justificaría en ... -
First all-sky search for continuous gravitational waves from unknown sources in binary systems
(2014)We present the first results of an all-sky search for continuous gravitational waves from unknown spinning neutron stars in binary systems using LIGO and Virgo data. Using a specially developed analysis program, the ... -
Generalized multi-terminal decoherent transport: recursive algorithms and applications to SASER and giant magnetoresistance
(2014)Decoherent transport in mesoscopic and nanoscopic systems can be formulated in terms of the D'Amato–Pastawski (DP) model. This generalizes the Landauer–Büttiker picture by considering a distribution of local decoherent ... -
Las potencialidades de la narrativa en la formación de profesores
(2014)Este artículo tiene como objetivo argumentar en relación con la potencialidad de los textos narrativos para la formación de profesores. Para sustentar nuestra argumentación tomaremos aportes teóricos de diversos autores ... -
Multimessenger search for sources of gravitational waves and high-energy neutrinos : results for initial LIGO-Virgo and IceCube
(2014-11-17)We report the results of a multimessenger search for coincident signals from the LIGO and Virgo gravitational-wave observatories and the partially completed IceCube high-energy neutrino detector, including periods of joint ... -
Geometric approach to extend Landau-Pollak uncertainty relations for positive operator-valued measures
(2014)We provide a twofold extension of Landau-Pollak uncertainty relations for mixed quantum states and for positive operator-valued measures, by recourse to geometric considerations. The generalization is based on metrics ...
