background: beta thalassemia gene mutations are among common mutations in southwest iran. however, hemoglobin e (hb e) and hb e/β⁰ thalassemia account for a small number of hemoglobinopathies in iran. this is the first study to directly address the existence of hb e and consequently hb e/β⁰ thalassemia in southwest iran. methods: this retrospective study discovered seven cases of hb e/β⁰ thalas...

The increase in new cases of drug resistance to first-line drugs such as ethambutol (ETB) makes it necessary develop improvements for antituberculosis drugs. A method improving the bioavailability active pharmaceutical ingredient (API) was investigated preventing and side-effects In this study, an delivery system using β-cyclodextrin (β-CD) supramolecular carrier ETB prepared kneading method. i...

We study the first-arrival (first-hitting) dynamics and efficiency of a one-dimensional random search model performing asymmetric Lévy flights by leveraging Fokker–Planck equation with δ-sink an space-fractional derivative operator stable index α asymmetry (skewness) parameter β. find exact analytical results for probability density times efficiency, we analyse their behaviour within limits sho...

Similarly to Parry’s characterization of β-expansions of real numbers in real bases β > 1, Ito and Sadahiro characterized digital expansions in negative bases, by the expansions of the endpoints of the fundamental interval. Parry also described the possible expansions of 1 in base β > 1. In the same vein, we characterize the sequences that occur as (−β)-expansion of −β β+1 for some β > 1. These...

Studies on the relative contribution of β 1- and β 2-adrenoceptors (AR) generally employ selective β 1- and β 2-AR antagonists such as CGP 20712A and ICI 118,551, respectively, and assume that antagonism by one of these compounds indicates mediation by the respective AR subtype. Here, we evaluated the β 2-AR-selectivity of ICI 118,551 in ventricular muscle strips of transgenic mice lacking β 1-...

In this paper we consider properties and power expressions of the functions f : (−1,1)→ R and fL : (−1,1)→ R, defined by f (x;γ) = 1 π ∫ 1 −1 (1+ xt)γ √ 1− t2 dt and fL(x;γ) = 1 π ∫ 1 −1 (1+ xt)γ log(1+ xt) √ 1− t2 dt, respectively, where γ is a real parameter, as well as some properties of a two parametric real-valued function D( · ;α,β ) : (−1,1)→ R, defined by D(x;α,β ) = f (x;β ) f (x;−α−1)...

In the following handout words and symbols in bold are R functions and words and symbols in italics are entries supplied by the user; underlined words and symbols are optional entries (all current as of version R-2.4.1). Sample texts from an R session are highlighted with gray shading. Suppose we prepare a calibration curve using four external standards and a reference, obtaining the data shown...

Pisot numbers, primitive matrices and beta-conjugates. We show that given a Pisot number β, for any integer n large enough, there is a nonnegative primitive square matrix whose order is equal to the degree of β, and the matrix admits β for eingenvalue. Let β = a1/β + a2/β + · · ·+ an/β + · · · be the β-expansion of β. For any Pisot number β, the sequence (an)n≥1 is ultimately periodic i.e., for...

Given β ∈ (1, 2), a β-expansion of a real x is a series in decreasing powers of β with coefficients 0 and 1 whose sum equals x. The aim of this note is to study certain problems related to the universality and combinatorics of β-expansions. Our main result is as follows: for each β ∈ (1, 2) and a.e. x ∈ (0, 1) there always exists a universal β-expansion of x in the sense of Erdős and Komornik, ...

In this work, we prove the existence of a solution for initial value problem nonlinear fractional differential equation with quadratic perturbations involving Caputo derivative ( cDα0+−ρt cDβ0+)(x(t)f(t,x(t)))=g(t,x(t)),t∈J=[0,1],1<α<2,0<β<α( cD0+α−ρt cD0+β)(x(t)f(t,x(t)))=g(t,x(t)),t∈J=[0,1],1<α<2,0<β<α conditions x0=x(0)f(0,x(0))x0=x(0)f...
