Solid-state studies of the crystalline/amorphous character in linear Poly(ethylenimine hydrochloride) (PEI-HCl) polymers and their copper complexes
(2015)Linear poly(ethylenimine hydrochloride) (PEI-HCl) polymers with different molecular weights (22, 87, and 217 kDa) and their copper complexes (Cu−PEI) were studied with particular attention to the crystalline/amorphous ... -
Strong cosmic censorship and Misner spacetime
(2015)Misner spacetime is among the simplest solutions of Einstein's equation that exhibits a Cauchy horizon with a smooth extension beyond it. Besides violating strong cosmic censorship, this extension contains closed timelike ... -
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 ... -
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, ... -
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 -
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 ... -
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 ... -
La realidad de los átomos
(2015)En este trabajo nos proponemos reconsiderar, desde una perspectiva histórica, la contribución de Albert Einstein a la de la teoría molecular de la realidad con sus trabajos sobre el movimiento Browniano. -
Neutrinos
(2015)En este artículo vamos a repasar brevemente el Modelo Estándar de Partículas, luego haremos una revisión cronológica del descubrimiento del neutrino. Por último mencionaremos el Observatorio de Neutrinos de Sudbury y ... -
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. -
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 ... -
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 ... -
Reaction rate in an evanescent random walkers system
(2015)Diffusion mediated reaction models are particularly ubiquitous in the description of phys-ical, chemical or biological processes. The random walk schema is a useful tool for formu-lating these models. Recently, evanescent ... -
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 ... -
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 ... -
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 meta-theory. Using techniques based on Normalisation by Evaluation, we prove that ... -
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 ... -
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 ... -
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 ...
