Review

, 2020
The chalcogen elements oxygen, sulfur, and selenium are essential constituents of side chain functions of natural amino acids. Conversely, no structural and biological function has been discovered so far for the heavier and more metallic tellurium ...

On (p, q)‐Analogue of Gamma Operators

Journal of Function Spaces, Volume 2019, Issue 1, 2019., 2019
In this paper, a kind of new analogue of Gamma type operators based on (p, q)‐integers is introduced. The Voronovskaja type asymptotic formula of these operators is investigated. And some other results of these operators are studied by means of modulus of continuity and Peetre K−functional.

Moment-angle complexes, monomial ideals, and Massey products

, 2006
Associated to every finite simplicial complex K there is a "moment-angle" finite CW-complex, Z_K; if K is a triangulation of a sphere, Z_K is a smooth, compact manifold.

Chronic wasting disease (CWD) in cervids

EFSA Journal, Volume 15, Issue 1, January 2017., 2017
Abstract In April and May of 2016, Norway confirmed two cases of chronic wasting disease (CWD) in a wild reindeer and a wild moose, respectively. In the light of this emerging issue, the European Commission requested EFSA to recommend surveillance activities and, if necessary, additional animal health risk‐based measures to prevent the introduction of ...

On Simultaneous Approximation of Modified Baskakov‐Durrmeyer Operators

International Journal of Analysis, Volume 2015, Issue 1, 2015., 2015
We discuss properties of modified Baskakov‐Durrmeyer‐Stancu (BDS) operators with parameter γ > 0. We compute the moments of these modified operators. Also, we establish pointwise convergence, Voronovskaja type asymptotic formula, and an error estimation in terms of second order modification of continuity of the function for the operators Bn,γα,β(f,x).

Rate of Convergence of Modified Baskakov‐Durrmeyer Type Operators for Functions of Bounded Variation

Journal of Difference Equations, Volume 2014, Issue 1, 2014., 2014
We study a certain integral modification of well‐known Baskakov operators with weight function of beta basis function. We establish rate of convergence for these operators for functions having derivative of bounded variation. Also, we discuss Stancu type generalization of these operators.

(p,q)-Generalization of Szasz-Mirakyan Operators

, 2015
In this paper, we introduce new modifications of Szasz-Mirakyan operators based on (p,q)-integers. We first give a recurrence relation for the moments of new operators and present explicit formula for the moments and central moments up to order 4.

Honey‐Induced Protein Stabilization as Studied by Fluorescein Isothiocyanate Fluorescence

The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013
Protein stabilizing potential of honey was studied on a model protein, bovine serum albumin (BSA), using extrinsic fluorescence of fluorescein isothiocyanate (FITC) as the probe. BSA was labelled with FITC using chemical coupling, and urea and thermal denaturation studies were performed on FITC‐labelled BSA (FITC‐BSA) both in the absence and presence ...

Helices 2 and 3 are the initiation sites in the PrPc -> PrPsc transition

, 2012
It is established that prion protein is the sole causative agent in a number of diseases in humans and animals. However, the nature of conformational changes that the normal cellular form PrPC undergoes in the conversion process to a self-replicating ...

A Bernstein‐Like Trigonometric Basis: Properties, Curve Design, and Operator Construction

Journal of Applied Mathematics, Volume 2025, Issue 1, 2025.
We introduce a novel family of trigonometric basis functions equipped with a shape parameter, analogous to Bernstein functions. These basis functions are employed to construct Bézier‐like curves, termed “trigo‐curves”, which retain the fundamental properties of classical Bézier curves while offering enhanced shape control through parameter adjustment ...
