We consider multipartite states of qubits and prove that their bipartite quantum entanglement, as quantified by the concurrence, satisfies a monogamy inequality conjectured by Coffman, Kundu, and Wootters. We relate this monogamy inequality to the concept of frustration of correlations in quantum spin systems.

We consider the four parameter bivariate generalised exponential distribution proposed by Kundu and Gupta (2009) and propose an EM algorithm to find the maximum likelihood estimators of the four parameters under random left censoring. A numerical experiment is carried out to discuss the properties of the estimators obtained iteratively.

This paper reflects the implementation of a reliable technique which is called $left(frac{G'}{G}right)$-expansion  ethod for  constructing exact travelling wave solutions of nonlinear partial  differential equations. The proposed algorithm has been successfully tested on two two selected equations, the balance numbers of which are not positive integers namely Kundu-Eckhaus equation and  Derivat...

In 2012, we registered a total of 22 species, 12 genera and five families of ptyctimous mites in India. Three new species, Apoplophora paraspinosa Niedbała sp. nov., Oribotritia duotrisetosa Niedbała sp. nov. and Plonaphacarus kaluzi Niedbała sp. nov., are described. Some remarks on descriptions of Indian Sumatrotritia inusitata Mahunka, 1989, Euphthiracarus meghalayensis Sanyal, 1988, Phthirac...
