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 ... -
Algebraic functions in quasiprimal algebras
(2014)A function is algebraic on an algebra A if it can be implicitly defined by a system of equations on A. In this note we give a semantic characterization for algebraic functions on quasiprimal algebras. This characterization ... -
Analysis of non-Markovian repairable fault trees through rare event simulation
(2022)Dynamic fault trees (DFTs) are widely adopted in industry to assess the dependability of safety-critical equipment. Since many systems are too large to be studied numerically, DFTs dependability is often analysed using ... -
Analysis of X-ray absorption spectra of the K and L 2,3 edges of GaN within the FP-LAPW method
(2016)Gallium nitride, GaN, is a semiconductor material with several technological applications and therapeutic potential to inhibits the proliferation of tumor cells. In this work we performed all electron self consistent ... -
Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams
(2016)The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ... -
Anisotropy-based mechanism for zigzag striped patterns in magnetic thin films
(2014)In this work, we studied a two-dimensional ferromagnetic system using Monte Carlo simulations. Our model includes exchange and dipolar interactions, a cubic anisotropy term, and uniaxial out-of-plane and in-plane ones. ... -
Asymptotic structure of the null surface formulation and the classical graviton
(2016)The dynamical equations for the null surface formulation of general relativity for purely radiative spacetimes are derived. Those asymptotically flat spacetimes describe the nonlinear evolution of gravitational radiation ... -
Axiomatizing bisimulation equivalences and metrics from probabilistic SOS rules
(2014)Probabilistic transition system specifications (PTSS) provide structural operational semantics for reactive probabilistic labeled transition systems. Bisimulation equivalences and bisimulation metrics are fundamental notions ... -
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 ... -
The Brauer-Picard group of the representation category of finite supergroup algebras
(2014)We develop further the techniques presented in a previous article (M. Mombelli. Abh. Math. Semin. Univ. Hamb. 82 (2012), 173–192), to study bimodule categories over the representation categories of arbitrary finite-dimensional ... -
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 ... -
Can we heal Chagas infection?
(2014)We present a model for the parasite-antibody dynamical competition between Trypanosoma rangeli and its antibodies during the acute phase of an infection in a mammal host. The model reproduces experimental data from murine ... -
Center of mass and spin for isolated sources of gravitational radiation
(2016)We define the center of mass and spin of an isolated system in general relativity. The resulting relationships between these variables and the total linear and angular momentum of the gravitational system are remarkably ... -
A certified extension of the Krivine machine for a call-by-name higher-order imperative language
(2014)In this paper we present a compiler that translates programs from an imperative higher-order language into a sequence of instructions for an abstract machine. We consider an extension of the Krivine machine for the ... -
Characterization, definability and separation via saturated models
(2014)Three important results about the expressivity of a modal logic L are the Characterization Theorem (that identifies a modal logic L as a fragment of a better known logic), the Definability theorem (that provides conditions ... -
Classification of integral modular categories of Frobenius–Perron dimension pq4 and p2q2
(2014)We classify integral modular categories of dimension pq4 and p2q2, where p and q are distinct primes. We show that such categories are always group-theoretical, except for categories of dimension 4q2. In these cases there ... -
Clustering and decoherence of correlated spins under double quantum dynamics
(2014)We present an improved approach for the study of the evolution of spin correlations and decoherence in multiple quantum nuclear magnetic resonance experiments. The infinite system, constituted by the protons of a polycrystalline ... -
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 ...
