Automatic classification of schizophrenia patients and healthy controls based on their 3-D MRI deformation images is introduced here. The image data are reduced by 2DPCA to avoid high computational expenses. Consecutively, reduced data are classified into the two groups according to the centroid method or the average linkage method. The results show that the algorithm gives better results while...

We introduce the idea of constructing hypothetical evolutionary trees using an incremental algorithm that inserts species one-by-one into the current evolutionary tree. The method of incremental phylogenetics by repeated insertions lead to an algorithm that can be used on DNA, RNA and amino acid sequences. According to experimental results on both synthetic and biological data, the new algorith...

This paper reports a simulation study comparing and evaluating the performance of different linguistic phylogeny reconstruction methods on model datasets for which the true trees are known. UPGMA performed least well, then (in ascending order) neighbor joining, the method of Gray & Atkinson and finally maximum parsimony. Weighting characters greatly improves the accuracy of maximum parsimony an...

Several methods for the estimation of functional diversity are employed in plant communities. However, it is hard to select the most suitable measures in practice. This work presents comparisons of nine distance-based measures applied to functional diversity analysis in forest communities (36 plots) along an elevational gradient in the Pangquangou Reserve, China. The employed indices and method...

Brazil is considered one of the domestication centers of cassava (Manihot esculenta), containing a large part of the biological diversity and traditional knowledge of the species. The aim of the present study was to evaluate the genetic diversity of cassava landraces grown by farmers in the north of Mato Grosso State, Brazil, using inter simple sequence repeat (ISSR) molecular markers. The stud...

There are several distinct tools to identify orthologous gene sequence from homologous gene sequence. Identification of orthologous gene is a major issue, and it is found that orthologous genes are responsible for any genetic disorders. In this paper we are focusing on hematologic disorders and found that orthologous genes are primary actor of haematological disorders. Here we present a novel a...

O objetivo desse trabalho foi determinar descritores morfológicos de acessos curauá através caracteres visando à avaliação dos germoplasmas, na Embrapa Amazônia Oriental, em Belém, PA. Foram estudados sete quantitativos 42 curauá, totalizando 210 indivíduos, conservados in vivo no Horto Plantas Medicinais. Os dados foram submetidos as analises multivariadas, realizado a seleção direta e com rea...

The number of experiments that allows the choice parents to be used in controlled crossings a more assertive way cluster analysis is unknown for plant architecture and grain yield traits common bean. Therefore, objective this work was determine should considered Tocher's unweighted pair group method with arithmetic mean (UPGMA) analyses identify promising bean several traits. Four were carried ...
