Adapting a Fourier pseudospectral method to Dirichlet boundary conditions for Rayleigh–Bénard convection
(2015)We present the adaptation to non–free boundary conditions of a pseudospectral method based on the (complex) Fourier transform. The method is applied to the numerical integration of the Oberbeck–Boussinesq equations in a ... -
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 ... -
Air core notch-coil magnet with variable geometry for fast-field-cycling NMR
(2015)In this manuscript we present details on the optimization, construction and performance of a wide-bore (71 mm) a-helical-cut notch-coil magnet with variable geometry for fast-field-cycling NMR. In addition to the usual ... -
Bounds for axially symmetric linear perturbations for the extreme Kerr black hole
(2015)We obtain remarkably simple integral bounds for axially symmetric linear perturbations for the extreme Kerr black hole in terms of conserved energies. From these estimates we deduce pointwise bounds for the perturbations ... -
Calibration method for confocal X-ray microanalysis with polychromatic excitation
(2015)To apply the fundamental parameters method at the confocal setup the knowledge of the sensitivity of the spectrometer is required which depends on the characteristics of two X-ray lenses: one in the excitation channel and ... -
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 ... -
Crossed extensions of the corepresentation category of finite supergroup algebras
(2015)We present explicit examples of finite tensor categories that are C2-graded extensions of the corepresentation category of certain finite-dimensional non-semisimple Hopf algebras -
Curvature flows for almost-hermitian Lie groups
(2015)We study curvature flows in the locally homogeneous case (e.g. compact quotients of Lie groups, solvmanifolds, nilmanifolds) in a unified way, by considering a generic flow under just a few natural conditions on the broad ... -
Depth distribution of martensite in plasma nitrided AISI H13 steel and its correlation to hardness
(2015)The depth distributions of hardness, nitrogen, and crystallographic phases in the diffusion zone of plasma nitrided AISI H13 steel were determined by microindentation, electron microprobe, grazing incidence X-ray diffraction, ... -
Directed search for gravitational waves from Scorpius X-1 with initial LIGO data
(2015)We present results of a search for continuously emitted gravitational radiation, directed at the brightest low-mass x-ray binary, Scorpius X-1. Our semicoherent analysis covers 10 days of LIGO S5 data ranging from 50–550 ... -
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 ... -
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 ... -
Examples of extensions of hopf algebras
(2015)We give some examples of, and raise some questions on, extensions of semisimple Hopf algebras. -
Una experiencia vivida en aula : enseñar y aprender a trabajar con estadística desde una perspectiva crítica
(2015)En este artículo se presenta una descripción de una experiencia escolar realizada en una escuela secundaria de una localidad de la provincia de Córdoba donde la segunda autora se desempeña como profesora de matemática. La ... -
Experimental determination of multiple ionization cross sections in Si by electron impact
(2015)The thin sample method is often used to experimentally determine ionization cross sections, specially when focusing on the low overvoltage region. The simplicity of the formalism involved in this method is very appealing, ... -
Experimental quantification of decoherence via the Loschmidt echo in a many spin system with scaled dipolar Hamiltonians
(2015)We performed Loschmidt echo nuclear magnetic resonance experiments to study decoherence under a scaled dipolar Hamiltonian by means of a symmetrical time-reversal pulse sequence denominated Proportionally Refocused Loschmidt ... -
Explicit matrix inverses for lower triangular matrices with entries involving Jacobi polynomials
(2015)For a two-parameter family of lower triangular matrices with entries involving Jacobi polynomials an explicit inverse is given, with entries involving a sum of two Jacobi polynomials. The formula simplifies in the Gegenbauer ... -
From a systems theory of sociology to modeling the onset and evolution of criminality
(2015)This paper proposes a systems theory approach to the modeling of onset and evolution of criminality in a territory. This approach aims at capturing the complexity features of social systems. Complexity is related to the ... -
Information extraction with active learning : a case study in legal text
(2015)Active learning has been successfully applied to a number of NLP tasks. In this paper, we present a study on Information Extraction for natural language licenses that need to be translated to RDF. The final purpose of our ... -
Internal - External stimulus competition in a system of interacting moving particles : persuasion vs propaganda
(2015)We propose a general nonlinear analytical framework to study the effect of an external stimulus in the internal state of a population of moving particles. This novel scheme allows us to study a broad range of excitation ...
