We introduce new distance measures for the construction and analysis of phylogenies, focusing on thioredoxin-fold proteins. Our distance measures for tree construction are based on several criteria, including pairwise alignment of only the thioredoxin fold region of each sequence, Hausdorff distance between sequences represented by sets of real vectors derived from per-residue features of the s...

The aim of this study was to compare the energy expenditure (EE) estimations of activity-specific prediction equations (ASPE) and of an artificial neural network (ANNEE) based on accelerometry with measured EE. Forty-three children (age: 9.8 ± 2.4 yr) performed eight different activities. They were equipped with one tri-axial accelerometer that collected data in 1-s epochs and a portable gas an...

the aim of this study was to use ahp method to rank the obstacles to improving professional ethics in sport media. in the first step, the existing obstacles were identified by review of literature, searching the authentic websites and finally interview with sport media experts. after this step, the hierarchy tree was portrayed to rank the obstacles and then the analytical hierarchy process (ahp...

With the aim of deriving a definitive phylogenetic tree for as many mammalian and avian herpesvirus species as possible, alignments were made of amino acid sequences from eight conserved and ubiquitously present genes of herpesviruses, with 48 virus species each represented by at least one gene. Phylogenetic trees for both single-gene and concatenated alignments were evaluated thoroughly by max...

background: type 1 diabetes is one of the chronic metabolic disorders among children and adolescents. peers are also important units in diabetes management through adolescence. this study aimed to evaluate the effectiveness of peer-based intervention in managing type 1 diabetes mellitus among children and adolescents.   methods: searching articles published prior to december 2013 in pubmed, web...

Fault Tree (FT) analysis is not only the most common technique used in engineering practice for estimation of system reliability, but also a key tool shared between designers, analysts, and regulators safe operation licensing purposes. In spite its long lasting success, traditional FT presents significant limitations modeling wide range features frequently encountered modern systems. The critic...

quantifying spatial structure is one of the most important components, describing natural ecosystems and their biodiversity. in this study, a set of indices and functions related to spatial structure using 102 established plots with an area of 1000 m2 were presented. to achieve spatial structure of carpinus-fagus type, a set of indices (clark & evans, uniform angle, shannon-wiener, mingling and...
