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 ... -
Un camino hacia la derivada : secuencia de actividades para construir el concepto de velocidad instantánea empleando la velocidad media
(2017)La siguiente propuesta tiene por objetivo introducir conceptos básicos del análisis diferencial. Está destinada a estudiantes de los últimos años de nivel secundario, de nivel terciario o de los primeros años de nivel ... -
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 ... -
The cohomology of filiform Lie algebras of maximal rank
(2014)We describe the structure of the cohomology of the filiform Lie algebras and as a module over their (2-dimensional) torus of derivations. Our approach relies on the fact that both filiform algebras have an ideal of codimension ... -
Completeness in hybrid type theory
(2014)We show that basic hybridization (adding nominals and @ operators) makes it possible to give straightforward Henkin-style completeness proofs even when the modal logic being hybridized is higher-order. The key ideas are ... -
Conjugacy classes of p-cycles of type D in alternating groups
(2014-10)We classify the conjugacy classes of $p$-cycles of type D in alternating groups. This finishes the open cases in [AFGV]. Also we determine all the subracks of those conjugacy classes which are not of type D. -
Constitutive hippocampal cholesterol loss underlies poor cognition in old rodents
(2014)Cognitive decline is one of the many characteristics of aging. Reduced long-term potentiation (LTP) and long-term depression (LTD) are thought to be responsible for this decline, although the precise mechanisms underlying ... -
Construction of a quartz spherical analyzer : application to high-resolution analysis of the Ni Ka emission spectrum
(2016)The construction and characterization of a focusing X-ray spherical analyzer based on α-quartz 4404 are presented. The performance of the analyzer was demonstrated by applying it to a high-resolution X-ray spectroscopy ... -
Critical exponents and scaling invariance in the absence of a critical point
(2016)The paramagnetic-to-ferromagnetic phase transition is classified as a critical phenomenon due to the power-law behaviour shown by thermodynamic observables when the Curie point is approached. Here we report the observation ... -
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 ... -
d-Dimensional KPZ equation as a stochastic gradient flow in an evolving landscape : interpretation and time evolution of its generating functional
(2017)The deterministic KPZ equation has been recently formulated as a gradient flow. Its non-equilibrium analog of a free energy—the “non-equilibrium potential” Φ[h], providing at each time the landscape where the stochastic ...
