PROPAGATING INTERFACES IN A TWO-LAYER BISTABLE NEURAL NETWORK
2006
The dynamics of propagating interfaces in a bistable neural network is investigated. We consider the network composed of two coupled 1D lattices and assume that they interact in a local spatial point (pin contact). The network unit is modeled by the FitzHugh–Nagumo-like system in a bistable oscillator mode. The interfaces describe the transition of the network units from the rest (unexcited) state to the excited state where each unit exhibits periodic sequences of excitation pulses or action potentials. We show how the localized inter-layer interaction provides an "excitatory" or "inhibitory" action to the oscillatory activity. In particular, we describe the interface propagation failure a…

Optimization of the Red Tilapia (Oreochromis spp.) Viscera Hydrolysis for Obtaining Iron-Binding Peptides and Evaluation of In Vitro Iron Bioavailabi…
2020
Iron deficiencies continue to cause significant health problems in vulnerable populations. A good strategy to combat mineral deficiency includes fortification with iron-binding peptides. This research aims to determine the optimal conditions to hydrolyze red tilapia viscera (RTV) using Alcalase 2.4 L and recovery of iron-binding protein hydrolysate. The result showed that under the optimal hydrolysis condition including pH 10, 60 °
Computing Subdivision Surface Intersection
2003
Computer surface intersections is fundamental problem in geometric modeling. Any Boolean operation can be seen as an intersection calculation followed by a selection of parts necessary for building the surface of the resulting object. This paper deals with the computing of intersection curveson subdivision surfaces (surfaces generated by the Loop scheme). We present three variants of our algorithm. The first variant calculates this intersection after classification of the object faces into intersecting and non-intersecting pairs of faces. the second variant is based on 1-neighborhood of the intersecting faces. The third variant uses the concept of bipartite graph.
Estar al otro lado de la mesa. Profesionales de los servicios públicos de empleo ante los dilemas de la activación laboral
2019
Under the paradigm of activation, the Public Employment Services has been reshaped by two levels of contractualization. On one hand, the collaboration of the administration with a network of agents on the programme scheme that make up the active policies of employment. On the other hand, the unemployed person?s access to a compartmentalized offer of services and individually taking responsibility for finding work. This double contractualization reveals redefinition of lowering public responsibility faced with the problem of unemployment that this activation supposes. This paper analyses how this redesign has an impact on how professionals serve the unemployed population. This lays bare, in …

Rayleigh-instability-driven dewetting of thin Au and Ag films on indium-tin-oxide surface under nanosecond laser irradiations
2013
Investigations have been carried out on laser-beam-induced nanoparticle (NP) formation in thin (5 nm) Au and Ag films on indium-tin-oxide substrate. After the irradiation the films were observed to break-up into NPs through a dewetting mechanism. This mechanism was investigated as a Rayleigh-instability- driven process. In fact, for each used laser fluence, the resulting Au and Ag NPs' mean size and surface-to-surface mean distance were quantified and correlated between them in the framework of the Rayleigh-instability theory showing an excellent agreement. © The Institution of Engineering and Technology 2013.

2023
Introducción. La denervación por radiofrecuencia de los ramos mediales lumbares es uno de los tratamientos más efectivos y con más evidencia para tratar el dolor lumbar crónico de origen facetario. Hipótesis. El uso de RF fría se relaciona con una mayor mejoría en la calidad de vida y en el control del dolor en comparación con el uso de la RFC en pacientes con dolor crónico de raquis lumbar de origen facetario. Material y Métodos. Estudio observacional de base individual con un seguimiento prospectivo de los pacientes, tamaño muestral de 61 pacientes, en el cual se comparan ambas modalidades de RF. Resultados. Los resultados en los cuestionarios ODI, SF-12, SALUD y HAD (cuestionario ansieda…
Topological canal foliations
2019
Regular canal surfaces of $\mathbb{R}^3$ or $\mathbb{S}^3$ admit foliations by circles: the characteristic circles of the envelope. In order to build a foliation of $\mathbb{S}^3$ with leaves being canal surfaces, one has to relax the condition “canal” a little (“weak canal condition”) in order to accept isolated umbilics. Here, we define a topological condition which generalizes this “weak canal” condition imposed on leaves, and classify the foliations of compact orientable 3-manifolds we can obtain this way.
