We investigate interlacing properties of zeros Laguerre polynomials Ln(α)(x) and Ln+1(α+k)(x), α>−1, where n∈N k∈{1,2}. prove that, in general, the these interlace partially not fully. The sharp t-interval within which two equal degree Ln(α+t)(x) are for every each α>−1 is 0<t≤ 2, [Driver K, Muldoon ME. Sharp interval polynomials.

the goal of this paper is to generalize the recently introduced summability method and introduce double statistical convergence of order  by using ideal. we also investigate certain properties of this convergence.

We consider a stochastic process with long-range dependence perturbed by multiplicative noise. The marginal distributions of both the original and noise have regularly-varying tails, tail indices α,α′>0, respectively. is taken as Karlin model, recently investigated model that has characterized memory parameter β∈(0,1). establish limit theorems for extremes reveal phase transition. In terms ther...

in spite of being histologically benign, sacrococcygeal teratoma (sct) may recur either as a benign or malignant tumor. a total of 26 patients with benign neonatal scts were treated in taleghanee and mofid medical centers from 1986 to 2000. investigations included radiography,abdominal ultrasound and computed tomography (ct) scan and measurement of tumor marker (α-fetoprotein). initial surgical...

objective: alpha-thalassemia is one of the most prevalent hemoglobin disorders in the world and it is a common hereditary condition caused by deletion of one or more α-globin genes. common α-thalassemia deletions like 3.7 kb, 4.2 kb, 20.5 kb and med can be detected by multiplex pcr. there are, however, some unknown deletions that can not be detected by the mentioned method or even by direct dna...
