Male germ line development in flowering plants is initiated with the formation of the generative cell that is the progenitor of the two sperm cells. While structural features of the generative cell are well documented, genetic programs required for generative cell cycle progression are unknown. We describe two novel Arabidopsis (Arabidopsis thaliana) mutants, duo pollen1 (duo1) and duo pollen2 ...

This study investigated the relationship between Iranian high school students’ Universal Grammar knowledge and their performance on such standardized general English proficiency tests as PET and FCE internationally administered by Cambridge University. To this end, 108 students were randomly chosen from some high schools located in Malayer from Hamedan. Since this study was correlational in nat...

Children are exposed to speech and other environmental evidence, from which they learn language. How do they do this? More specifically, how do children map from complex, physical signals to grammars that enable them to generate and interpret new utterances from their language? This thesis presents a computational theory of unsupervised language acquisition. By computational we mean that the th...

Within the last few years generative modeling techniques have gained attention especially in the context of cultural heritage. As a generative model describes a rather ideal object than a real one, generative techniques are a basis for object description and classification. This procedural knowledge differs from other kinds of knowledge, such as declarative knowledge, in a significant way. It c...

principles of judicial review in administrative law are basic criteria developed through judicial decisions. most of these principles have a legal value in modern administrative law. in this paper some of these principles and criteria have been studied in switzerland administrative law. in this country the legality, equality, public interest, good faith, hearing and proportionality principles h...

graphite oxide constitutes carbon network with oxygen atoms both on hexagonal arrangement and the edge sites. structural and electronic properties for graphite-oxygen complexes have been explored using first-principles total-energy calculations within the local density approximation (lda). band structures and density of states for the propose carbon 3d models are reported. a finite energy gap and...

Computer generated 3D forms using generative procedures have matured in the last decade and now considered as a tangible approach for realizing architectural design ideas. As fascinating as the approach might be, it is still lacking actual application in the early architectural design process. There are many reasons for this, among them: it has many implications over the architectural design pr...
