BACKGROUND The clinical validation of the EARL harmonization program for standardised uptake value (SUV) metrics is well documented; however, its potential for defining metabolic active tumour volume (MATV) has not yet been investigated. We aimed to compare delineation of MATV on images reconstructed using conventional ordered subset expectation maximisation (OSEM) with those reconstructed usin...

The food needs for increasing population, climatic changes, urbanization and industrialization, along with the destruction of forests, are main challenges modern life. Therefore, it is very important to evaluate plant genetic resources in order cope these problems. this study, a set ninety-one walnut (Juglans regia L.) accessions from Central Anatolia region, composed seventy-four eight commerc...

pomegranate is an importantly popular fruit crop with iran the main center of its diversity throghout the world. the richest pomegranate genetic resources believed to exist in iran. the present investigation was carried out to study the genetic diversity of 15 genotypes of pomegranate in tarume zanjan making use of rapd markers. genomic dna was extracted from the plant,s leaf, and tested for th...

This study aimed to evaluate the clustering pattern consistency of soybean (Glycine max) lines, using seven different clustering methods. Our aim was to evaluate the best method for the identification of promising genotypes to obtain segregating populations. We used 51 generations F5 and F6 soybean lines originating from different hybridizations and backcrosses obtained from the soybean breedin...

Plot-to-plot dissimilarity measures are considered a valuable tool for understanding the complex ecological mechanisms that drive community composition. Traditional presence/absence coefficients are usually based on different combinations of the matching/mismatching components of the 2 × 2 contingency table. However, more recently, dissimilarity measures that incorporate information about the d...

In the paper some types of equivalences over resemblance measures and some basic results about them are given. Based on induced partial orderings on the set of unordered pairs of units a dissimilarity between two resemblance measures over finite set of units can be defined. As an example, using this dissimilarity standard association coefficients between binary vectors are compared both theoret...

A crucial issue in dissimilarity-based classification is the choice of the representation set. In the small sample case, classifiers capable of a good generalization and the injection or addition of extra information allow to overcome the representational limitations. In this paper, we present a new approach for enriching dissimilarity representations. It is based on the concept of feature line...

The quinone profiles of microbial biomass samples from wastewater and natural aquatic environments were studied. A soil sample was alse analyzed for comparison. Attempts were made to perform numerical analyses on these profiles by using three pararneters, the microbial divergence index (MD,), the bioenergetic divergence index (BD,), and the dissimilarity ndex (D), and the algorithm of the neigh...

We compare two successful discriminative classification algorithms on three databases from the UCI and STATLOG repositories. The two approaches are the log-linear model for the class posterior probabilities and class-dependent weighted dissimilarity measures for nearest neighbor classifiers. The experiments show that the maximum entropy based log-linear classifier performs better for the equiva...
