Three kinds of sclerotia of Typhula spp. from Ardabil, East Azerbaijan and Qazvin Provinces in the northwest of Iran were collected. Morphology and ITS sequences of rDNA suggested that the collected fungi belonged to Typhula incarnata Lasch, Typhula phacorrhiza (Reichardt) Fr. and Typhula sp. These three taxa are new records in the Middle East and the result of this research suggests that Iran ...

G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection between g-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a bounded operator.

Pasteurella multocida isa gram-negative bacterial pathogen that is causative agent of a wide range of diseases in many animal species and humans. Lipopolysaccharides (LPS) are an important virulence factor, minor changes to structure of which can exert dramatic effects on pathogenicity of P. multocida in its host. LPS can be used for the identification and classification of strains with somatic...

g-frames in hilbert spaces are a redundant set of operators which yield a repre-sentation for each vector in the space. in this paper we investigate the connection betweeng-frames, g-orthonormal bases and g-riesz bases. we show that a family of bounded opera-tors is a g-bessel sequences if and only if the gram matrix associated to its denes a boundedoperator.

Initiation, Response, and Feedback(IRF) sequences are the most frequent interaction network in any classroom contexts. IRF sequences have been examined profusely in previous studies and were reported to be negatively correlated with participation opportunities (Kasper, 2006; Cazden, 2001; Ellis, 1994).In all these studies, all contingent factors of any classroom context which might influence in...

We present a self-learning approach for synthesizing programs from integer sequences. Our method relies on tree search guided by learned policy. system is tested the On-Line Encyclopedia of Integer Sequences. There, it discovers, its own, solutions 27987 sequences starting basic operators and without human-written training examples.

Sergentomyia sintoni is the natural vector of Sauroleishmania species of lizards. This sandfly isabundance in and around the burrows of great gerbils. S. sintoni was collected from peridomestic animalshelters, inside and around houses and also from the nearby burrows of the gerbil reservoir hosts,Rhombomys opimus, in several provinces of Iran. Mitochondrial Cytochrome b (Cyt b) of sandflies, wh...

The cysteine-rich 8K protein of Potato mop-top virus (PMTV) suppresses host RNA silencing. In this study, evolutionary analysisof 8K sequences of PMTV isolates was studied on the basis of nucleotide and amino acid sequences. Twenty-one positively selected sites were identified in 8K codingregions. Recombination events were found in the 8K of PMTV isolates with a rate of 1.8. Totally 30 haplotyp...

In this paper, we give some determinantal and permanental representations of generalized Lucas polynomials, which are a general form of generalized bivariate Lucas p-polynomials, ordinary Lucas and Perrin sequences etc., by using various Hessenberg matrices. In addition, we show that determinant and permanent of these Hessenberg matrices can be obtained by using combinations. Then we show, the ...
