This study has been undertaken to find out the synoptic and dynamical conditions those have helped in genesis intensification of tropical cyclone Amphan. It found that, under favourable high SST, energy weak vertical shear horizontal wind, 200 hPa STWJ The shear, high-temperature gradient between warmer sea surface & colder atmosphere strong upper-level divergence increased heat moisture ex...

The hypergeometric distributions have many important applications, but they not had sufficient attention in information theory. Hypergeometric can be approximated by binomial or Poisson distributions. In this paper we present upper and lower bounds on divergence. These are for statistical testing a better understanding of the notion exchange-ability.

Recently, we have used the symmetric bracket of vector fields, and developed the notion of the symmetric derivation. Using this machinery, we have defined the concept of symmetric curvature. This concept is natural and is related to the notions divergence and Laplacian of vector fields. This concept is also related to the derivations on the algebra of symmetric forms which has been discu...

Linear mountain wave theory is used to derive the general formulas of the gravity wave momentum flux (WMF) and its vertical divergence that develop in directionally sheared flows with constant vertical shear. Height variations of theWMF and its vertical divergence are studied for a circular bell-shapedmountain. The results show that the magnitude of the WMF decreases with height owing to variab...

In long-lived clonal plants, the overall size of a clone is often used to estimate clone age. The size of a clone, however, might be largely determined by physical or biotic interactions, obscuring the relationship between clone size and age. Here, we use the accumulation of mutations at 14 microsatellite loci to estimate clone age in trembling aspen (Populus tremuloides) from southwestern Cana...

An important aspect of SVM-based speaker verification is the choice of dynamic kernel. Recently there has been interest in the use of kernels based on the Kullback-Leibler divergence between GMMs. Since this has no closed-form solution, typically a matched-pair upper bound is used instead. This places significant restrictions on the forms of model structure that may be used. All GMMs must conta...

In this paper we further develop the theory of f-divergences for log-concave functions and their related inequalities. We establish Pinsker inequalities new affine invariant entropy obtain on functional surface area lower upper bounds Kullback-Leibler divergence in terms area. The lead to L_p-affine areas convex bodies.

In 2013 Zhou et al. concluded that Salmonella enterica serovar Agona represents a genetically monomorphic lineage of recent ancestry, whose most recent common ancestor existed in 1932, or earlier. The Abstract stated 'Agona consists of three lineages with minimal mutational diversity: only 846 single nucleotide polymorphisms (SNPs) have accumulated in the non-repetitive, core genome since Agona...

the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...
