Consider a non-symetric generalized diffusion X(·) in R d determined by the differential operator A(x) = − ij ∂iaij (x)∂j + i bi(x)∂i. In this paper the diffusion process is approximated by Markov jump processes Xn(·) in homogeneous and isotropic grids Gn ⊂ R d which converge in distribution to diffusion. The generators of Xn(·) are constructed explicitly. Due to the homogeneity and isotropy of...

Microprocessor roadmaps clearly show a trend towards multiple core CPUs. Modern operating systems already make use of these CPU architectures by distributing tasks between processing cores thereby increasing system performance. This review article highlights a brief introduction of what a multicore system is, the various methods adopted to program these systems and also the industrial applicati...

Symetric designs are interesting objects of combinatorics, and have some relations with coding theory, difference sets, geometry finite group theory. They applications on statistics design experiments. In the present paper we study an existing problem for symmetric due to Bruck, Ryser Chowla write algorithm by using their theorem called BRC Theorem.

The reaction between barbituric acid or 2-thiobarbituric acid and different benzaldehydes, dependent upon the applied reaction conditions, selectively yields three different product types, i.e. 5-benzylidene(thio)barbituric acids II, symetric Michael adducts III or 5-phenyl-1H-pyrano[2,3-d]pyrimidine-2,4(3H,5H)-diones and 5-phenyl-2-thioxo-2,3-dihydro-1H-pyrano[2,3-d]pyrimidin-4(5H)-ones IV. Th...

background: the sperm count and function may be affected by karyotype abnormalities or microdeletion in y chromosome. these genetic abnormalities can probably transmit to the children. objective: in this study, we tried to determine the frequency of karyotype abnormalities and y chromosome microdeletions in severe oligospermic or azoospermic men who fathered sons by icsi. materials and methods:...

In this article we study the field of Hilbertian metrics and positive definit (pd) kernels on probability measures, they have a real interest in kernel methods. Firstly we will make a study based on the Alpha-Beta-divergence to have a Hilbercan metric by proposing an improvement of this divergence by constructing it so that its is symmetrical the Alpha-Beta-Symmetric-divergence (ABS-divergence)...

All the well known exactly solvable s−wave potentials V (r), r ∈ (0, ∞) may be PT −symmetrically regularized (say, by a " small " imaginary shift of the coordinate axis) and redefined as acting on the whole real line, r → x−i ε, x ∈ (−∞, ∞). There is no surprise that the new models are still exactly solvable and that their energies remain real. What is an unexpected result? The observed drastic...

Indigofera santapaui Sanjappa is little-known species and reported from very few localities of the north Western Ghats. In present investigation, somatic chromosome number (2n=16) karyotype analysis were for first time in I. santapaui. The formula was observed to be 2n=16=12m+4sm. Karyotype fell 2B asymmetric category Stebbins’ classification.

Definition 1. A graph G is a t × t grid if it consists of t 2 vertices forming a square t × t such that every two consecutive vertices in a row or in a colum are connected. As a result of previous excercises we know that a treewidth of a t × t grid is t. A treewidth of a graph can only decrease as a result of taking minors so we can conclude that if a graph contain a t × t grid as a minor it's ...
