ÐA very interesting recent development in data compression is the Burrows-Wheeler Transformation [1]. The idea is to permute the input sequence in such a way that characters with a similar context are grouped together. We provide a thorough analysis of the Burrows-Wheeler Transformation from an information theoretic point of view. Based on this analysis, the main part of the paper systematicall...

Background: Oat (Avena sativa) with high nutritive value and fiber content is used as the main food grain in many countries for human diet as well as animal feed. Recently, it became difficult to transfer new genes through the conventional breeding due to the lack of desirable traits. Objectives: The current study aimed at achieving a st...

We propose simple transformation of the hidden states in variational Bayesian factor analysis models to speed up the learning procedure. The speed-up is achieved by using proper parameterization of the posterior approximation which allows joint optimization of its individual factors, thus the transformation is theoretically justified. We derive the transformation formulae for variational Bayesi...

background: hemorrhagic transformation (ht) of ischemic stroke (is) is a detrimental complication. this study investigated the association between serum ferritin level and ht in patients with massive is of middle cerebral artery.   methods: thirty patients with massive is of middle cerebral artery were enrolled in this prospective cohort study. they were divided into two groups based on the ser...

This paper focuses on developing models to study influential factors on the inflation rate for a panel of available countries in the World Bank data base during 2008-2012‎. ‎For this purpose‎, Random effect log-linear and Ordinal logistic models are used for the analysis of continuous and categorical inflation rate variables‎. ‎As the original inflation rate response to variables shows an appar...

Background: A highly efficient genetic transformation system is essential for a successful genetic manipulation of the African violet (Saintpaulia ionantha Wendl.). Objectives: Developing a particle bombardment-based genetic transformation system for the African violet. Materials and Methods: A local cultivar of the African violet from Guilan province was used for transformation experiments. Th...

We studied the effects of different media for callus induction and differentiation, and pre-culture period of immature wheat embryo culture on biolistic transformation efficiency for including antifreeze gene KN2 and bar conferring resistance to the herbicide bialaphos. The percentage of plantlets generated from induction and differentiation media without Cu2+ was lower than those cultured on d...

Organizations all over the world are transforming digitally. However, success rate of such transformations is minimal. To increase chance a successful transformation, leaders organizations going for digital transformation must have management capabilities (TMCs).

let $g$ be a finite simple graph whose vertices and edges are weighted by two functions. in this paper we shall define and calculate entropy of a dynamical system on weights of the graph $g$, by using the weights of vertices and edges of $g$. we examine the conditions under which entropy of the dynamical system is zero, possitive or $+infty$. at the end it is shown that, for $rin [0,+infty]$, t...

myths show the layers of human being's collective unconsciousness and include a  nations' symbolic and mysterious conceptions. banugoshasbnameh is a mythic verse book including mythic functions. in banugoshasbnameh, banugoshasb is a warring and heroic archetype. her functions remind the glory of   women's role in agricultural era, the era which is famed for its matriarchy and in ...
