AbstractMulti-layer perceptron artificial neural networks (MLP-ANNs) were used to predict the concentration of digoxin needed to obtain a cardio-activity of specific biophysical parameters in Tivela stultorum hearts. The inputs of the neural networks were the minimum an...

AbstractThe aim of this revisión is to highlight recent evidence that links low quality and quantity of sleep with an increased propensity to develop overweight or obesity. In this text we present evidence obtained with controlled clinical studies as well as with experi...

ResumenSe presenta una revisión del trabajo de varios autores (entre ellos pedagogos, psicólogos educativos, filósofos, profesores y responsables de instituciones educativas), relativa a nueve aspectos educativos de gran importancia en la organización escolar y en la pr...

AbstractArc-locally semicomplete digraphs were introduced by Bang-Jensen as a common generalization of both semicomplete and semicomplete bipartite digraphs in 1993. Later, Bang-Jensen (2004), Galeana-Sánchez and Goldfeder (2009) and Wang and Wang (2009) provided a char...

ResumenLa detección del cáncer cervicouterino con citología disminuyó su incidencia en más del 50%. La causa de este cáncer son virus del papiloma humano de alto riesgo. Se requiere de una prueba sensible que proporcione la sensibilidad y especificidad suficientes para ...

In this paper we look for periodic orbits for a Lagrangian system in a complete Riemannian manifold under the action of an eventually unbounded potential. An upper bound on the fixed period is obtained by means of variational tools involving penalization arguments and M...

Abstract This paper presents the results of the characterization of a photonic crystal fiber stretch (PCF). The characterization is essential to know the actual parameters of the PCF for its use in subsequent projects. With the characterization results it is easier to s...

Abstract In the past decade the space sector has been developing solutions to support the timely response to natural and man-made disasters. The Italian COSMO-SkyMed constellation is providing a significant contribution to this goal providing timely and accurate radar i...

A kernel N of a digraph D is an independent set of vertices of D such that for every x ∈ V(D) - N there exists an arc from x to N. A digraph D is M-oriented if each directed triangle has at least two symmetrical arcs. The covering number of a digraph D denoted by θ(D) i...
