The rapidly increasing number of spoken-dialogue systems have led to numerous robust parsers for limited domains having been constructed during the last decade. By “parsing” we here mean a mapping from the input utterance to a context-independent semantic representation. By “robust” we mean that the parser will give a reasonable result even on very noisy input. In simple spoken-dialogue applica...

data related to holstein dairy cattle from 1987 to 2004 were obtained from animal breeding center of iran to estimate the genetic and phenotypic trends. variance components and genetic parameters of the first lactation records were estimated using restricted maximum likelihood method and aireml algorithm through matvec program. animal breeding values were predicted through multiple-trait animal...

background blastocystis is a common protozoan parasite in mammals, birds, amphibians,reptiles, fish, arthropods, and annelids. this parasite has some subtypes, which pathogenicity status of them still remained controversial. some of blastocystis subtypes are potentially pathogenic to human. objectives this study has identified the b. hominis subtypes and their prevalence rates in hamadan. patie...

recent advances in dna based technology have made available a wide range of molecular characteristics for taxonomic and systematic studies of malaria vectors. one region of the anopheline mosquito genome that has received particular attention is the ribosomal dna. in this study, mosquitoes of the anopheles superpictus collected from a wide geographical distribution of iran were investigated for...

genetic diversity is one of the three levels of biodiversity. the aim of present study was to compare levels of genetic polymorphism between wild bream populations using seven microsatellite loci. genetic diversity was investigated by studying samples collected from two regions, the coast of chamkhale and bandaranzali of gilan province. a total of seven microsatellite loci (mfw7, mfw26, mcs1eh,...

the aim of the present study was to find the best or optimum topology of six chicken populations, which were genotyped based on nine highly polymorphic microsatellite markers. to reach this goal, different genetic distances based on infinite allele model (iam), stepwise mutation model (smm) and drawing phylogentic trees on un-weighted pair-group method using arithmetic averages (upgma) method w...
