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 ...
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 algebrasEjemplos de extensiones de álgebras de Hopf
(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 ...
