we prove that the class of profinite groups $g$ that have a factorization $g=ab$ with $a$ and $b$ abelian closed subgroups, is closed under taking inverse limits of surjective inverse systems. this is a generalization of a recent result by k. h. hofmann and f. g. russo. as an application we reprove their generalization of iwasawa's structure theorem for quasihamiltonian pro-$p$...
Upper bounds on the CP asymmetry relevant for leptogenesis are reexamined and found weaker than in previous literature, both for hierarchical and for quasi-degenerate righthanded neutrinos. Successful leptogenesis implies the usual lower bound on right-handed neutrino masses, and an upper bound on left-handed neutrino masses (which we obtain to be 0.15 eV at 3σ) only if right-handed neutrinos a...
An investigation on the symmetry of total teeth size in the right and left sides of dental arches among people with normal occlusion Dr. M. Zarringhalam* *- Assistant professor of Orthodontics Dept. Faculty of Dentistry Mashhad University of Medical Sciences. Background and aim: Considering slight asymmetry between the left and right sizes of body along with the right and left sides of the ...
In this paper, we prove that some stabilizing controllers of a plant, which admits a left/right-coprime factorization, have a special form where their stable and unstable parts are separated. The dimension of the unstable part depends on the algebraic concept of stable range of the ring A of SISO stable plants. Moreover, we prove that, if the stable range of A is equal to 1, then every plant—de...
A factorization system (E ,M) on a category A gives rise to the covariant category-valued pseudofunctor P of A sending each object to its slice category over M. This article characterizes the P so obtained as follows: their object images have terminal objects, and they admit bicategorically cartesian liftings, up to equivalence, of slice-category projections. It is clear that, and how, (E ,M) c...
A classical result in the theory of Hopf algebras concerns the uniqueness and existence of inte-grals: for an arbitrary Hopf algebra, the integral space has dimension ≤ 1, and for a finite dimensional Hopf algebra, this dimension is exaclty one. We generalize these results to quasi-Hopf algebras and dual quasi-Hopf algebras. In particular, it will follow that the bijectivity of the antipode fol...
An R-module is called semi-endosimple if it has no proper fully invariant essential submodules. For a quasi-projective retractable module MR we show that M is finitely generated semi-endosimple if and only if the endomorphism ring of M is a finite direct sum of simple rings. For an arbitrary module M , conditions equivalent to the semi-endosimplicity of its quasi-injective hull are found. As co...
Notions of strongly regular, regular and left(right) regular $Gamma$−semigroupsare introduced. Equivalent conditions are obtained through fuzzy notion for a$Gamma$−semigroup to be either strongly regular or regular or left regular.
Purpose: This study is designed to determine the sex differences in volume of the left parahippocampal cortex in right-handed normal subjects and the right-handed subjects which were suffered from Alzheimer and parkinson diseases. Materials and Methods: This study was performed on 72 normal human brains (38 males, 34 females), 11 brains suffered from Alzheimer (4 males, 7 females), and 13 brai...
