in this paper, we derive rst some results on the shannon entropyin order statistics and their concomitants arising from a sequence of f(xi; yi): i = 1; 2; :::g independent and identically distributed (iid) random variablesfrom the bivariate normal distribution and extend our results to a collectionc(x; y ) = f(xr1:n; y[r1:n]); (xr2:n; y[r2:n]); :::; (xrk:n; y[rk:n])g of order sta-tistics and t...

introduction: peripheral vascular disease (pvd) is a major cause of morbidity and is associated with coronary artery disease (cad). we aimed to perform lower limb perfusion scan (llps) in patients referred for myocardial perfusion imaging (mpi) and estimate prevalence of pvd in subgroups with normal and abnormal mpi results. we also compared quantitative indices of llps in patients with and wit...

Let G be a group. We denote by ν(G) certain extension of the non-abelian tensor square G⊗G G×G. In this paper we prove that derived subgroup ν(G)′ is central product three normal subgroups ν(G), all isomorphic to G⊗G. As consequence, describe structure each term and lower series group ν(G).
