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 ...
Generalization of entropy based divergence measures for symbolic sequence analysis
(2014)
Entropy based measures have been frequently used in symbolic sequence analysis. A symmetrized and smoothed form of Kullback-Leibler divergence or relative entropy, the Jensen-Shannon divergence (JSD), is of particular ...
Structure of the Ru, Ag and Te L X-ray emission spectra
(2016)
The emission of X-rays in atomic transitions from L-shell vacancy states of Ru, Ag and Te induced by electron incidence was studied. To this end, L X-ray spectra were measured with a wavelength dispersive spectrometer, and ...
Isomorphism and disorder in o-chlorohalobenzenes studied by NQR
(2014)
In this work we present experimental results that allow to characterize different solid modifications found in o-chlorohalobenzenes. Three disordered phases have been found in o-chlorobromobenzene. The stable phase at ...
One-dimensional singular problems involving the p-Laplacian and nonlinearities indefinite in sign
(2016)
Let Ω be a bounded open interval, let p > 1 and γ >, and let m : Ω → ℝ be a function that may change sign in Ω. In this article we study the existence and nonexistence of positive solutions for one-dimensional singular ...
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 ...
Experimental determination of L X-ray fluorescence cross sections for elements with 45 < Z < 50 at 10 keV
(2014)
Synchrotron radiation at 10 keV was used to experimentally determine the Ll, La, LbI ,LbII , LgI and LgII fluorescence cross sections for elements with 45 < Z < 50, as part of an ongoing investigation at low energies. The ...
Spectra of lens spaces from 1-norm spectra of congruence lattices
(2016)
To every n-dimensional lens space L, we associate a congruence lattice L in Zm, with n = 2m−1 and we prove a formula relating the multiplicities of Hodge-Laplace eigenvalues on L with the number of lattice elements of a ...
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 ...
