DNA flows between chromosomes and mobile elements, following rules that are poorly understood. This limited knowledge is partly explained by the limits of current approaches to study the structure and evolution of genetic diversity. Network analyses of 119,381 homologous DNA families, sampled from 111 cellular genomes and from 165,529 phage, plasmid, and environmental virome sequences, offer ch...

implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...

In the present study, mitochondrial DNA polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was used to assess the population structure and genetic relationships among six Persian sturgeon, Acipenser persicus populations from south Caspian Sea along the Iranian coast. The complete nucleotide dehydrogenase subunit 5 (NADH 5) region of mtDNA amplified by PCR was di...

‎The most challenging task in dealing with Bayesian networks is learning their structure‎. ‎Two classical approaches are often used for learning Bayesian network structure;‎ ‎Constraint-Based method and Score-and-Search-Based one‎. ‎But neither the first nor the second one are completely satisfactory‎. ‎Therefore the heuristic search such as Genetic Alg...

Phylogenetic relationships and genetic variation between two Iranian sheep breeds were analyzed using cytochrome b (cyt-b) gene sequences. The genomic DNA was isolated by salting out method and amplified cytochrome b gene using polymerase chain reaction restriction (PCR) method with a pair of primer. A partial sequence of cyt-b gene of Iranian sheep is 780 bp and contained 13 variable sites and...

The genetic diversity and phylogenetic structure was analyzed in Marghoz goat population by mitochondrial DNA sequences. Phylogenetic analysis was carried out using hyper variable region 1 (968 bp) obtained form 40 animals. Marghoz goat proved to be extremely diverse (average haplotype diversity of 0.999) and the nucleotide diversity values 0.022. A total of 40 Marghoz goats were grouped into s...

Abstract Community genetics is an applied research area that explores the role of genetic variables on the interactions and community structure determinism affecting species. Community genetics covers a spectrum from services, genetic and congenital disorders, genetic counseling, prevention and screening to macro policies. The focal point of community genetics is the society, and community-o...

in this paper, the optimal location and characteristics of tadas dampers in moment resisting steel structures, considering the application of minimum number of tadas dampers in a building as an objective function and the restriction for destruction of main members is studied. genetic algorithm in first generation randomly produces different chromosomes representing unique tadas dampers distribu...

This study was conducted in order to investigate genetic diversity and population structure of pike-perch in the Northern part of Iran. For this purpose, 207 adult pike-perches from four regions of the Caspian Sea watershed (Talesh Coasts, Anzali Wetland, Chaboksar Coasts and Aras Dam) were collected. DNA was extracted and by using 15 pairs of microsatellite primers, Polymerase Chain Reaction (...
