Objective: The study aimed to determine the effect of eight weeks high intensity interval (HIIT) and sub-maximal continuous trainings on plasma betatrophin level in diabetic rats treated with metformin. Materials and Methods: In this experimental study, 42 diabetic wistar rats were divided into six groups (n=7): diabetic control (C), diabetic control + metformin consumption(C+M), diabetic HIIT...

Let λ(m) denote the maximal absolute projection constant over real m-dimensional subspaces. This quantity is extremely hard to determine exactly, as testified by fact that only known value of for m>1 λ(2)=4/3. There also numerical evidence indicating λ(3)=(1+5)/2. In this paper, relying on a new construction certain mutually unbiased equiangular tight frames, we show λ(5)≥5(11+65)/59≈2.06919. c...

The aim of this paper is using the majorization technique to identify the classes of trees with extermal (minimal or maximal) value of some topological indices, among all trees of order n ≥ 12

Objective: In this study, we aimed to validate the accuracy of computed tomography-based attenuation correction (CTAC) using the bilinear scaling method.Methods: The measured attenuation coefficient (μm) was compared to a theoretical attenuation coefficient (μt ) using four different CT scanners and an RMI 467 phantom. The effective energy of the CT beam X-rays was calculated, using the aluminu...

We consider the problem of constructing nonnegative matrices with prescribed extremal singular values. In particular, given 2n−1 real numbers σ ( j) 1 and σ ( j) j , j = 1, . . . , n, we construct an n×n nonnegative bidiagonal matrix B and an n×n nonnegative semi-bordered diagonal matrix C , such that σ ( j) 1 and σ ( j) j are, respectively, the minimal and the maximal singular values of certai...

Let K be a complete field with a discrete valuation v, ring of integers OK , and maximal ideal (πK). Let k := OK/(πK) be the residue field, assumed to be separably closed of characteristic p ≥ 0. Let A/K be any abelian variety of dimension g. Let A/OK denote its Néron model, with special fiber Ak/k and group of components ΦA,K . Let A′/K denote the dual abelian variety, with Néron model A/OK an...

(Here ΛE is a suitable period lattice commensurable with the Néron lattice of E.) The function Φ, which is transcendental as a function of τ , enjoys the following notable algebraicity property, a consequence of the theory of complex multiplication: Theorem HP: Let K ⊂ C be a quadratic imaginary extension of Q, and let K denote its maximal abelian extension. If τ belongs to H ∩ K, then Φ(τ) bel...
