We present a novel approach to disentangle two key contributions the largest-scale anisotropy of galaxy distribution: (i) intrinsic dipole due clustering and anisotropic geometry, (ii) kinematic our peculiar velocity. Including redshift angular size galaxies, in addition their fluxes positions allows us measure both direction amplitude velocity independently source distribution. find that this ...

Background: Beta thalassemia is one of the autosomal recessive diseases that related to synthesis disorder of beta globin chain. It is caused by any of the more than 200 mutations in the β-globin gene. DNA sequencing and genotyping of numerous mutations at beta globin gene is timely and expensive. Therefore, the best method for screening is linkage using polymorph markers at beta globin region ...

امروزه ترکیبات آلاینده‎ آلی به‎وسیله فعالیت های انسانی، از راه های متفاوتی تولید می شوند. این آلاینده‎ها به‎دلیل ویژگی های جهش‎زایی، سرطان‎زایی و سمیت بالایی که دارند برای محیط زیست و موجودات زنده خطرناک هستند. این مواد نسبتاً فرارند و نیمه عمر طولانی دارند لذا تخریب و از بین بردن آلاینده های آلی به‎روش هایی که برای محیط زیست مضر نباشد، مهم است. با توجه به کاربرد گسترده زئولیت‎ها در جذب آلاینده‎...

The high molecular mass protein, HD1, is a structural protein present in hemidesmosomes as well as in distinct adhesion structures termed type II hemidesmosomes. We have studied the distribution and expression of HD1 in the GD25 cells, derived from murine embryonal stem cells deficient for the beta 1 integrin subunit. We report here that these cells possess HD1 but not BP230 or BP180; two other...

This work presents a metaheuristic based on the use of the beta distribution as a search distribution for solving numerical optimization problems in search spaces defined on two sided intervals. The innovation of this work lies on the efficiency of the proposed method to estimate the parameters of the beta distribution with a minimal cost for each decision variable by using the method of moment...

We investigated the distribution and diurnal variation of TR(beta)1 protein expression in liver with specific antibodies against TR(beta)1. Immunohistochemistry showed a zonal distribution of TR(beta)1 with maximum expression in the pericentral zone matching some known T(3)-responsive enzyme activities in the liver, such as glutamine synthetase, cholesterol 7alpha- hydroxylase, and spot 14. Com...

We compute analytically, for large N, the probability distribution of the number of positive eigenvalues (the index N+) of a random N x N matrix belonging to Gaussian orthogonal (beta=1), unitary (beta=2) or symplectic (beta=4) ensembles. The distribution of the fraction of positive eigenvalues c=N+/N scales, for large N, as P(c,N) approximately = exp[-betaN(2)Phi(c)] where the rate function Ph...
