Método Multi-Híbrido FEM-MoM-PO para el Análisis de Problemas de Dispersión y Radiación

A general fully coupled multi-hybrid method in three dimensions (3D) combining the Finite Element Method (FEM), the Method of Moments (MoM), and a high frequency asymptotic technique, Physical Optics (PO), is presented. Complex radiating structures are analyzed with FEM (which easily handles complex geometries, permeable materials, anisotropy, and so on) while small and medium size perfect electric conductor (PEC) objects are rigorously analyzed using MoM; large PEC objects can be efficiently analyzed with PO. Furthermore, different regions of the same object can be modeled with MoM and PO. That provides the possibility, for instance, of taking into account the edge effects of PEC objects without the need of introducing artificial line currents at the edges, as the Physical Theory of Diffraction (PTD) does. Several numerical results are presented showing the validity of the method

Leukemia multiclass assessment and classification from Microarray and RNA-seq technologies integration at gene expression level

In more recent years, a significant increase in the number of available biological experiments has taken place due to the widespread use of massive sequencing data. Furthermore, the continuous developments in the machine learning and in the high performance computing areas, are allowing a faster and more efficient analysis and processing of this type of data. However, biological information about a certain disease is normally widespread due to the use of different sequencing technologies and different manufacturers, in different experiments along the years around the world. Thus, nowadays it is of paramount importance to attain a correct integration of biologically-related data in order to achieve genuine benefits from them. For this purpose, this work presents an integration of multiple Microarray and RNA-seq platforms, which has led to the design of a multiclass study by collecting samples from the main four types of leukemia, quantified at gene expression. Subsequently, in order to find a set of differentially expressed genes with the highest discernment capability among different types of leukemia, an innovative parameter referred to as coverage is presented here. This parameter allows assessing the number of different pathologies that a certain gen is able to discern. It has been evaluated together with other widely known parameters under assessment of an ANOVA statistical test which corroborated its filtering power when the identified genes are subjected to a machine learning process at multiclass level. The optimal tuning of gene extraction evaluated parameters by means of this statistical test led to the selection of 42 highly relevant expressed genes. By the use of minimum- Redundancy Maximum-Relevance (mRMR) feature selection algorithm, these genes were reordered and assessed under the operation of four different classification techniques. Outstanding results were achieved by taking exclusively the first ten genes of the ranking into consideration. Finally, specific literature was consulted on this last subset of genes, revealing the occurrence of practically all of them with biological processes related to leukemia. At sight of these results, this study underlines the relevance of considering a new parameter which facilitates the identification of highly valid expressed genes for simultaneously discerning multiple types of leukemia.This work was supported by Project TIN2015-71873-R (Spanish Ministry of Economy and Competitiveness -MINECO- and the European Regional Development Fund -ERDF) and Junta de Andalucı´a (P12–TIC–2082)

Seed germination of four amaranth species (Amaranthus spp.)

Amaranth (Amarantus spp.) is an important species for its benefits in human and animal nutrition, therefore, the reproduction of these species is important, supported by rigorous experiments that generate quality information. Consequently, the present work aimed to determine the germination of 20 accessions of four species of Amaranthus spp. This was carried out at the Technological Institute of Chiná, Campeche, Mexico, with seeds donated by The North Central Regional Plant Introduction Station (NCRPIS), Iowa State University, from Africa, Asia, Greece, South America, USA, and Mexico. The seeds were weighed and measured, then they were sown in Petri dishes and kept in a germination chamber at 27 ºC and a relative humidity of 54 % in the dark, every 24 hours the germinated seeds were counted and removed. The analyzes were performed using the ANOVA test to identify differences in weight, length and germination between accessions. The results did not show statistical differences in seed length, between species or between accessions, with respect to weight if there were statistical differences both between species and between accessions. The results showed that A. hypochondriacus from India had the highest weight (0.00093 ± 0.000075 g). Germination did obtain statistical differences in the different evaluation times, at 24 and 48 hours, where the highest germination was in the species A. hypochondriacus and A cruentus. Therefore, it is concluded that seed germination is different in each species and accession.Amaranthus (Amaranthus spp.) is a species of great importance that benefits human and animal nutrition; therefore, its reproduction must be based on useful information obtained from rigorous experiments.
