We describe a simple, conceptual forward analysis procedure for ∞-complete WSTS S. This computes the so-called clover of a state. When S is the completion of a WSTS X, the clover in S is a finite description of the downward closure of the reachability set. We show that such completions are ∞-complete exactly when X is an ω-WSTS , a new robust class of WSTS. We show that our procedure terminates...

Genetic modification of plants by the insertion of transgenes can be a powerful experimental approach to answer basic questions about gene product function. This technology can also be used to make improved crop varieties for use in the field. To apply this powerful tool to red clover, an important forage legume, a population of red clover with a high potential for regeneration in tissue cultur...

In this paper building statistical language models for Persian language using a corpus and incorporating them in Persian continuous speech recognition (CSR) system are described. We used Persian Text Corpus for building the language models. First we preprocessed the texts of corpus by correcting the different orthography of words. Also, the number of POS tags was decreased by clustering POS tag...

Numerous studies have investigated the health problems reported by veterans of the Persian Gulf War, but important questions remain. Epidemiologic studies have consistently indicated that Gulf War veterans report unexplained symptoms at significantly higher rates than veteran comparison groups but that they have not experienced excess rates of disease-related mortality. Addressing unanswered qu...

The main concern of the present study was to compare Iranian monolingual and bilingual EFL students’ listening comprehension in terms of Latinized Persian subtitling of English movie to see whether there was a significant difference between monolinguals and bilinguals on immediate linguistic comprehension of the movie. Latinized Persian subtitling was representing Persian language in Latin scri...

Russian ( ), Persian ( ) and Siberian ( Acipenser gueldenstaedtii A. persicus A. ) sturgeons are closely related ‘Ponto-Caspian’ species. Investigation of baerii their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, ‘baerii-like’ mitochondrial genotypes were found in the Caspian Sea among 3...

Although much has been written about the Gulf conflict, comparatively little attention has been paid to the medical aspects of the conflict and to the overall balance between the costs and benefits. As the situation continues to evolve in Iraq it becomes clearer that some of the short term effects of the war given so much publicity will be overshadowed by the medium and long term adverse conseq...

In this paper I present the prepositional system of Persian. I show that Persian prepositions can be divided into three classes (Class 1, Class 2a and Class 2b) which exhibit distinct syntactic behavior. Then I examine the question of the categorial status of Class 2 prepositions and demonstrate that they are not to be regarded as nouns. Finally I present the extended PP projection of Persian s...
