Curvature flows for almosthermitian 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 ... 
Directed search for gravitational waves from Scorpius X1 with initial LIGO data
(2015)We present results of a search for continuously emitted gravitational radiation, directed at the brightest lowmass xray binary, Scorpius X1. 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 ... 
Advanced LIGO
(2015)The Advanced LIGO gravitational wave detectors are secondgeneration instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA, USA. The two instruments are identical in design, and ... 
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 Gravitationalwave Observatory (LIGO) science data run. The targets were nine young supernova remnants not ... 
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 2forms. We show that when the Lie group is compact equipped with a ... 
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 ... 
Co100xFex magnetic thick films prepared by electrodeposition
(2015)Co–Fe films are grown onto plane pretreated 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 lowfield 1H nuclearmagnetic 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 ... 
Air core notchcoil magnet with variable geometry for fastfieldcycling NMR
(2015)In this manuscript we present details on the optimization, construction and performance of a widebore (71 mm) ahelicalcut notchcoil magnet with variable geometry for fastfieldcycling NMR. In addition to the usual ... 
Weighted estimates for integral operators on local BMO type spaces
(2015)We prove the weighted boundedness for a family of integral operators Tα on Lebesgue spaces and local BMO type spaces. To this end we show that Tα can be controlled by the Calder ́on operator and a local maximal operator. ... 
Pure type systems with explicit substitutions
(2015)We introduce a new formulation of pure type systems (PTSs) with explicit substitution and de Bruijn indices and formally prove some of its metatheory. Using techniques based on Normalisation by Evaluation, we prove that ... 
Monte Carlo simulation of characteristic secondary fluorescence in electron probe microanalysis of homogeneous samples using the splitting technique
(2015)Electron probe microanalysis (EPMA) is based on the comparison of characteristic intensities induced by monoenergetic electrons. When the electron beam ionizes inner atomic shells and these ionizations cause the emission ... 
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 ... 
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 Xray diffraction, ... 
Smart sampling for lightweight verification of Markov decision processes
(2015)Markov decision processes (MDP) are useful to model optimisation problems in concurrent systems. To verify MDPs with efficient Monte Carlo techniques requires that their nondeterminism be resolved by a scheduler. Recent ... 
Rare event simulation with fully automated Importance splitting
(2015)Probabilistic model checking is a powerful tool for analysing probabilistic systems but it can only be efficiently applied to Markov models. Monte Carlo simulation provides an alternative for the generality of stochastic ... 
A statistical study of heterogeneous nucleation of ice by molecular dynamics
(2015)We studied the stochastic nature of heterogeneous nucleation of supercooled liquid water by molecular dynamics simulations. The systems were composed of 768 molecules; M of them had their positions restricted forming a ... 
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 ... 
A multivariate geostatistical approach for landscape classification from remotely sensed image data
(2015)This paper proposes a methodology to address the classification of images that have been acquired from remote sensors. One common problem in classification is the high dimensionality of multivariate characteristics. The ...
