Landau-Zener and Rabi oscillations in the spin-dependent conductance
(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. ... -
The lattice of congruences of a finite line frame
(2017)Let F = <F, R> be a finite Kripke frame. A congruence of F is a bisimulation of F that is also an equivalence relation on F. The set of all congruences of F is a lattice under the inclusion ordering. In this article we ... -
Layered double hydroxides-indomethacin nanohybrids : intercalation, pH influence, stability and release properties
(2016)In this work, three pH values (8, 9 and 10) were studied for the insertion of Indomethacin (Indo) molecules into Layered Double Hydroxides (LDHs). The obtained results showed that the LDH materials have been a good storage ... -
Lie subalgebras of the matrix quantum pseudodifferential operators
(2016)We give a complete description of the anti-involutions that preserve the principal gradation of the algebra of matrix quantum pseudodifferential operators and we describe the Lie subalgebras of their minus fixed points. -
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 ... -
Lightning in Western Patagonia
(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 ... -
Localization of the valence electron of endohedrally confined hydrogen, lithium and sodium in fullerene cages
(2016)The localization of the valence electron of H, Li and N a atoms enclosed by three different fullerene molecules is studied. The structure of the fullerene molecules is used to calculate the equilibrium position of the ... -
Looking for fairer societies, can hard sciences help? : Comment on “Modeling human behavior in economics and social science” by Marina Dolfin, Leone Leonida and Nisrine Outada
(2017)Comment on "Modeling human behavior in economics and social science" by Marina Dolfin, Leone Leonida and Nisrine Outada. -
Magnetite NPs@C with highly-efficient peroxidase-like catalytic activity as an improved biosensing strategy for selective glucose detection
(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
(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 ... -
MaskD : a tool for measuring masking fault-tolerance
(2022-03-30)We present MaskD, an automated tool designed to measure the level of fault-tolerance provided by software components. The tool focuses on measuring masking fault-tolerance, that is, the kind of fault-tolerance that allows ... -
Matrix Gegenbauer polynomials : the 2×2 fundamental cases
(2016)In this paper, we exhibit explicitly a sequence of 2 × 2 matrix valued orthogonal polynomials with respect to a weight W p,n , for any pair of real numbers p and n such that 0 < p < n. The entries of these polynomiales ... -
Maximal totally geodesic submanifolds and index of symmetric spaces
(2016)Let M be an irreducible Riemannian symmetric space. The index i(M ) of M is the minimal codimension of a totally geodesic submanifold of M. In [1] we proved that i(M ) is bounded from below by the rank rk(M) of M, that is, ... -
Memory and long-range correlations in chess games
(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 ... -
A methodology to determine natural radioactivity by γ spectrometry without using calibrated standard samples
(2017)When determining the radioactivity in materials by γ spectra, different processes are involved difficulting the fit. Besides, calibrated standard samples are necessary. In this work we propose a methodology to determine ... -
Methods and results of a search for gravitational waves associated with gamma-ray bursts using the GEO 600, LIGO, and Virgo detectors
(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. ... -
Una mirada sobre el operativo aprender
(2017)El artículo presenta algunas reflexiones en torno al operativo de evaluación "Aprender". -
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) ... -
Modeling polymeric gels : the role of chain flexibility on the structure of physical gels
(2017)Using molecular dynamics simulations and a simple model for chain molecules we study the gel formation under different conditions. The main characteristic of the model is the short attractive range of the non-bonding ... -
Modeling spatial patterns in the visual cortex
(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 ...
