Some design methods based on Petri nets modify the original specification by behaviour-preserving insertion of new transitions. If the unfolding prefix is used to analyse the net, it has to be re-unfolded after each modification, which is detrimental for the overall performance. The approach presented in this paper applies the transformations directly to the unfolding prefix, thus avoiding re-u...

To study mosquito ( Diptera : Culicidae) fauna in Guilan province (Caspian sea littoral , North of Iran ), an investigation was carried out during April to December 2000. The whole set of 2478 adult specimens from 64 habitats and 6656 larvae from 127 larval breeding places was collected . Three species of the genus Culiseta were identified as follow: 1- Cs. longiareolata 2- Cs. morsitans 3- Cs....

Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment of infections. Nanomedicines such as chitosan can carry multiple drugs and improve the therapeutic effects of antibiotics. Objectives: The study aimed to synthesis and characterization of ciprofloxacin loaded chitosan nanoparticle for eradication biofilm of P. aeroginosa. Methods: Cipro-CS microparticles...

Text Classification is an important research field in information retrieval and text mining. The main task in text classification is to assign text documents in predefined categories based on documents’ contents and labeled-training samples. Since word detection is a difficult and time consuming task in Persian language, Bayesian text classifier is an appropriate approach to deal with different...

background: osteonecrosis (on) is known to be one of the most disabling complications following corticosteroid (cs) medications. however, evidence regarding risk of asymptomatic prevalence of on among different diseases and the impact of variable steroid regimens are conflicting. we aimed to determine the prevalence of on of femoral head in asymptomatic patients with systemic rheumatic diseases...

In recent years, use of biodegradable polymers based nanoparticles has received highinterest in the development of vaccines delivery vehicles. The aim of study was to preparechitosan nanoparticles (CS NPs) for loading Echis carinatus (EC) venom and evaluate theirpotential as an adjuvant and antigen delivery system on a pilot scale. CS NPs were preparedusing ionic gelation method, and their char...

the study was carried out to investigate the effects of camelia (camelina sativa l. crantz) variety (cs) oil or seeds on performance, meat quality, immunity and plasma metabolic profile in broiler chickens. the broilers (n= 2,080, cobb 500) were randomly allocated (sex ratio 1:1) for 32-day experimental periods (from 11d to 42 d) to 4 experimental groups: control (corn-soybean meal-full fat soy...

The paper develops novel algorithms for time-varying (TV) sparse channel estimation in Massive multiple-input, multiple-output (MMIMO) systems. This is achieved by employing a reduced (non-uniformly spaced tap) delay-line equalizer, which can be related to low/reduced rank filters. low filter implemented deriving an innovative TV (Krylov-space based) Multi-Stage Kalman Filter (MSKF), appropriat...

A novel probabilistic sparsity-promoting method for robust near-field (NF) antenna characterization is proposed. It leverages on the measurements-by-design (MebD) paradigm, and it exploits some a priori information under test (AUT) to generate an overcomplete representation basis. Accordingly, problem at hand reformulated in compressive sensing (CS) framework as retrieval of maximally sparse di...
