UPGMA analysis, principal component analysis, genetic diversity analysis and genetic distance analysis of RAPD data were used to assess the extent of host specialization in 50 isolates of S. homoeocarpa from five turfgrass hosts. In UPGMA analysis and principal component analysis, the occurrence of host specialization was not readily apparent based on visual inspection. Genetic diversity analys...

Specialization and its Application to Program Parallelization Germán Puebla and Manuel Hermenegildo {german,herme}@fi.upm.es Department of Computer Science Technical University of Madrid (UPM) Abstract. Program specialization optimizes programs for known valúes of the input. It is often the case that the set of possible input valúes is unknown, or this set is infinite. However, a form of specia...

Females of brood parasitic shiny cowbirds, Molothrus bonariensis, search and prospect host nests, synchronizing parasitism with laying. This behavior is sex-specific, as females perform this task without male's assistance. Host nests must be removed from the female’s memory "library" after being parasitized, to avoid repeated parasitism, or when they become unavailable because predation. Thus, ...

We investigated variation in the abundance-prevalence relationships of fleas among 17 different flea-host associations as well as among different species of hosts and fleas in the Negev desert. We explored variation in the value of exponent of Taylor's power relationship with changes in flea community size and flea specialization (host specificity and seasonal pattern of activity). We tested if...

Background: The clinical and pathological evaluation of oral lesions are very important in this field. The purpose of this study was to assess clinico- pathological agreement on 232 cases with oral lesion s.Methods: The consecutive files of 232 patients with oral lesions from pathological laboratory archives of Babol Dental faculty and Shahid Beheshti Hospital were reviewed and the data include...
