Both sides agree that it is correct, but they disagree on what the symbols mean. For frequentists, probabilities refer to the fraction that an event happens over repeated samples. They think of probability as counting, or an extension of combinatorics. For Bayesians, probabilities refer to degrees of belief, or, if you want, the odds that you would place on a bet. They see probability as an ext...

Haloxylon aphyllum (Minkw.) Iljin is a treelike shrub from the Chenopodiaceae family with thick, gnarled, highly branched trunk dark gray bark. It propagated by seeds. The most typical conditions of natural habitat are valley-like depressions ridges and hollows hilly sands, valleys channels old rivers, often more or less close groundwater occurrence, as well takyrs takyr-like serozem soils. Bla...

Cadmium can be found in wastewater in high concentrations and can cause dangerous effect on aqueous environment and human health. At present, many methods have been used to heavy metals removal. Among this clean up techniques, adsorption techniques by using low-cost adsorbent are more considerable. In this study, batch adsorption experiments were conducted for removal of cadmium ions from a...

black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...

The r-parity tensor of a graph is a generalization of the adjacency matrix, where the tensor’s entries denote the parity of the number of edges in subgraphs induced by r distinct vertices. For r = 2, it is the adjacency matrix with 1’s for edges and −1’s for nonedges. It is well-known that the 2-norm of the adjacency matrix of a random graph is O( √ n). Here we show that the 2-norm of the r-par...

We consider the (l, d) Planted Motif Search Problem, a problem that arises from the need to find transcription factor-binding sites in genomic information. We propose the algorithms PMSi and PMSP which are based on ideas considered in PMS1 [6]. These algorithms are exact, make use of less space than the known exact algorithms such as PMS and are able to tackle instances with large values of d. ...

The article provides information on large degraded areas in almost all areas, of which 17.5 million hectares dry natural pastures are allocated for cattle breeding out 32 desert and semi-desert Uzbekistan. It is also noted that 40% have to varying degrees, the average productivity has decreased by 20-30%, 8.0 should be improved first. To improve condition pastures, authors it possible increase ...

in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

As natural forest cover declines, planted forests have come to occupy an increasing percentage of the earth's surface, yet we know little about their suitability as alternative habitat for wildlife. Although some primate species use planted forests, few studies have compared primate populations in natural and nearby planted forests. From March 2006 to July 2010, we conducted line transect surve...

We propose a simple modification of a well-known Random Walk algorithm for solving the Satisfiability problem and analyze its performance on random CNFs with a planted solution. We rigorously prove that the new algorithm solves the Full CNF with high probability, and for random CNFs with a planted solution of high density finds an assignment that differs from the planted in only ε-fraction of v...
