A methodology to determine natural radioactivity by γ spectrometry without using calibrated standard samples
(2017)
When determining the radioactivity in materials by γ spectra, different processes are involved difficulting the fit. Besides, calibrated standard samples are necessary. In this work we propose a methodology to determine ...
The lattice of congruences of a finite line frame
(2017)
Let F = <F, R> be a finite Kripke frame. A congruence of F is a bisimulation of F that is also an equivalence relation on F. The set of all congruences of F is a lattice under the inclusion ordering. In this article we ...
An image quality index based on coefficients of spatial association with an application to image fusion
(2018)
In the last decade, image quality indices have received considerable attention to quantify the dissimilarity between two images. The codispersion coefficient, commonly used in spatial statistics to address the association ...

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 ...
Structural and magnetic properties of nanocrystalline Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) synthesized by a mechanochemical route
(2017)
Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) powders were prepared by means of a solid acid-base reaction induced by mechanochemical energy. Bi, La and Fe chlorides were high-energy ball-milled with NaOH, yielding a mixture of Bi1-xLaxFeO3 ...
Entanglement generation through particle detection in systems of identical fermions
(2017)
We investigate the generation of entanglement in systems of identical fermions through a process involving particle detection, focusing on the implications that this kind of processes have for the concept of entanglement ...
The fractal organization of ultradian rhythms in avian behavior
(2017)
Living systems exhibit non-randomly organized biochemical, physiological, and behavioral processes that follow distinctive patterns. In particular, animal behavior displays both fractal dynamics and periodic rhythms yet ...
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 ...
Structural and magnetic influence of yttrium-for-iron substitution in cobalt ferrite
(2017)
Yttrium-substituted cobalt ferrites of nominal composition CoY x Fe 1.98-xO4 , x=0; 0.1; 0.2; 0.3, were prepared using the sol-gel combustion method. A slight iron deficiency in the formulation was designed in order to ...
