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 ... -
Dynamic characterization of crystalline and glass phases of deuterated 1,1,2,2 tetrachloroethane
(2015)A thorough characterization of the γ, β, and glass phases of deuterated 1,1,2,2 tetrachloroethane (C2D2Cl4) via nuclear quadrupole resonance and Molecular Dynamic Simulations (MDSs) is reported. The presence of molecular ... -
Advanced LIGO
(2015)The Advanced LIGO gravitational wave detectors are second-generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA, USA. The two instruments are identical in design, and ... -
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 ... -
Searches for continuous gravitational waves from nine young supernova remnants
(2015)We describe directed searches for continuous gravitational waves (GWs) in data from the sixth Laser Interferometer Gravitational-wave Observatory (LIGO) science data run. The targets were nine young supernova remnants not ... -
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 ... -
Influence of the incorporation of fibers in biscuit dough on proton mobility characterized by time domain NMR
(2016)The effect of fiber addition on the distribution and mobility of protons in biscuits is studied by using low resolution time domain Nuclear Magnetic Resonance (TD-NMR). The proportion of flour is reduced in order to ... -
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 ... -
On the evolution of the momentarily static radiation free data in the Apostolatos - Thorne cylindrical shell model
(2014-02-24)In this paper we study the evolution of the 'Momentarily Static and Radiation Free' (MSRF) initial data for the Apostolatos–Thorne cylindrical shell model. After briefly reviewing the equations of motion, the definition ... -
Invariant solutions to the conformal Killing–Yano equation on Lie groups
(2015)We search for invariant solutions of the conformal Killing–Yano equation on Lie groups equipped with left invariant Riemannian metrics, focusing on 2-forms. We show that when the Lie group is compact equipped with a ... -
Invertible bimodule categories over the representation category of a Hopf algebra
(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 ... -
On Dirichlet problems with singular nonlinearity of indefinite sign
(2015)Let Ω be a smooth bounded domain in RN , N ≥ 1, let K, M be two nonnegative functions and let α, γ > 0. We study existence and nonexistence of positive solutions for singular problems of the form −Δu = K(x)u−α − λM (x)u−γ ... -
Implementation of an F-statistic all-sky search for continuous gravitational waves in Virgo VSR1 data
(2014)We present an implementation of the F -statistic to carry out the first search in data from the Virgo laser interferometric gravitational wave detector for periodic gravitational waves from a priori unknown, isolated ... -
Co100-xFex magnetic thick films prepared by electrodeposition
(2015)Co–Fe films are grown onto plane pre-treated Cu foils; the effects of the alloy composition on the morphology and the crystal texture of the electrodeposited films and their anisotropic magnetic hysteresis properties are ... -
Effects of magnetic field gradients on the aggregation dynamics of colloidal magnetic nanoparticles
(2015)We have used low-field 1H nuclear-magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) to investigate the aggregation dynamics of magnetic particles in ionic ferrofluids (IFFs) in the presence of magnetic field ... -
