Let n ∈ N − {1}, and let A be a Banach algebra. An additive map D : A → A is called n-Jordan derivation if D(a) = D(a)a + aD(a)a + ...+ aD(a)a+ aD(a), for all a ∈ A. Using fixed point methods, we investigate the stability of n–Jordan derivations (n–Jordan ∗−derivations) on Banach algebras (C∗−algebras). Also we show that to each approximate ∗−Jordan derivation f in a C∗− algebra there correspon...

introduction: to report the experience of the jordan university hospital with respect to the surgical treatment of otosclerosis and to compare results and complications with published studies.   materials and methods: the medical records of all patients who underwent stapes surgery for otosclerosis at the jordan university hospital during the period january 2003 to december 2010 were reviewed. ...

Bethe ansatz solution of the two-axis two-spin Hamiltonian is derived based on Jordan-Schwinger boson realization SU(2) algebra. It shown that equations can be obtained as zeros related extended Heine-Stieltjes polynomials. Symmetry properties excited levels system and polynomials are discussed. As an example application theory, two equal spin case studied in detail, which demonstrates each ban...

OBJECTIVE Non-Hodgkin lymphoma (NHL) is one of the most frequent malignancies in Jordan. The aims of this study are: 1. To classify NHL cases in Jordan, using the new World Health Organization (WHO) classification system, 2. To identify the most common types of NHL in Jordan, and 3. To compare lymphoma types and patterns in Jordan with those in surrounding countries and the West. METHODS We s...

We point out that in non-Hermitian systems, Jordan decomposition should replace eigendecomposition so all ``good approximate eigenstates'' of the system are identified. These states can be resonantly excited. As a concrete example, we study location and field distribution zero-energy corner quadrupole insulator (QI) split parameter space into three distinct regimes according to properties state...

background : the incidence of thyroid cancer has varied from 2 per 100,000 in europe to 21 per 100,000 in the hawaiian chinese population and is 2-3 fold more common in females. middle east cancer consortium figures from 1996-2001 have recorded different age standardized incidence rates that ranged from 2 per 100,000 in egypt to 7.5 per 100,000 among israeli jews. in jordan the age standardized...

Any linear transformation can be represented by its matrix representation. In an ideal situation, all linear operators can be represented by a diagonal matrix. However, in the real world, there exist many linear operators that are not diagonalizable. This gives rise to the need for developing a system to provide a beautiful matrix representation for a linear operator that is not diagonalizable....

This theory provides a compact formulation of Gauss-Jordan elimination for matrices represented as functions. Its distinctive feature is succinctness. It is not meant for large computations. 1 Gauss-Jordan elimination algorithm theory Gauss-Jordan-Elim-Fun imports Main begin Matrices are functions: type-synonym ′a matrix = nat ⇒ nat ⇒ ′a In order to restrict to finite matrices, a matrix is usua...

Abstract Analbuminemia is a rare autosomal recessive disease characterized by extremely low or zero levels of circulating serum albumin. The diagnosis made ruling out other causes hypoalbuminemia and should be confirmed gene mutation analysis. In this article, we describe the clinical findings preterm neonate born to consanguineous family who presented with progressive lower limb edema at age 7...
