objective(s): helicobacter pylori, a human specific gastric pathogen is a causative agent of chronic active gastritis. the vacuolating cytotoxin (vaca) is an effective virulence factor involved in gastric injury. the aim of this study was to construct a recombinant protein containing antigenic region of vaca gene and determine its antigenicity.   materials and methods: the antigenic region of v...

introduction: the persian squirrel (sciurus anomalus) is considered the only well-known species of the family sciuridae in the middle east. since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. so far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. hence, this research was performed to fil...

One of the important issues in data envelopment analysis (DEA) is sensitivity analysis. Heretofore the existent studies have considered the data modification of inputs and outputs in one or multiple DMUs. In this paper the number of DMUs is increased and a stability region is obtained in  by applying defining hyperplanes in which if the added DMU (only one DMU) is in this region then all of the...

In this paper we run two important methods for solving some well-known problems and make a comparison on their performance and efficiency in solving nonlinear systems of equations‎. ‎One of these methods is a non-monotone adaptive trust region strategy and another one is a scaled trust region approach‎. ‎Each of methods showed fast convergence in special problems and slow convergence in other o...

Region inference is a type-based technique for determining runtime memory management at compile time. It is targeted at a runtime model in which the store consists of a stack of regions and memory management predominantly consists of pushing and popping regions. Region inference has previously been speciied by a set of inference rules, which formalize when regions may be allocated and deallo-ca...
