Some approximation properties of ( p , q ) $(p,q)$ -Bernstein operators

Journal of Inequalities and Applications, 2016
This paper is concerned with the ( p , q ) $(p,q)$ -analog of Bernstein operators. It is proved that, when the function is convex, the ( p , q ) $(p,q)$ -Bernstein operators are monotonic decreasing, as in the classical case.

Bernstein-type operators that reproduce exponential functions [PDF]

Journal of Mathematical Inequalities, 2018
Summary: In this paper we recover a generalization of the classical Bernstein operators introduced by \textit{S. Morigi} and \textit{M. Neamtu} [Adv. Comput. Math. 12, No. 2--3, 133--149 (2000; Zbl 1044.42500)]. Specifically, we focus on a sequence of operators that reproduce the exponential functions \(\exp(\mu t)\) and \(\exp(2\mu t)\), \(\mu > 0 ...

What Could Have Been: Predicted and Actual Exclusion by Potential Romantic Partners and Platonic Friends

European Journal of Social Psychology, EarlyView.
ABSTRACT Romantic partners are instrumental to more goals than friends, and therefore, people have more to lose when denied a romantic relationship than a friendship. We explored people's forecasted and experienced rejection by a potential romantic partner or friend.

Stancu type q-Bernstein operators with shifted knots

Journal of Inequalities and Applications, 2020
In the present paper, Stancu type generalizations of the q-analog of Lupaş Bernstein operators with shifted knots are introduced. Some approximation results and rate of convergence for these operators are investigated.

Bernstein-type operators and their derivatives

Journal of Approximation Theory, 1989
This paper is concerned with the Bernstein-type integral operators given by \[ M_ n(f,x)=(n+1)\sum^{n}_{k=0}P_{n,k}(x)\int^{1}_{0}P_{n,k}(t)f(t) dt, \] where \(P_{n,k}(x)=\left( \begin{matrix} n\\ k\end{matrix} \right)x^ k(1-x)^{n-k}\). It is known that they have nice properties. The authors study the relation between derivatives of \(M_ nf\), the rate

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Iterated Boolean Sums of Bernstein Type Operators

Numerical Functional Analysis and Optimization, 2020
The approximation of functions using linear positive operators is affected by saturation. The quality of approximation offered by iterated Boolean sums increases with the regularity of the function...

Testing a Relational Model of Workplace Spirituality Across Three Levels: Linking Employee Attitudes and Turnover in a Healthcare Setting

Human Resource Development Quarterly, EarlyView.
ABSTRACT A growing body of research demonstrates that purpose and meaning are significant to employee well‐being and organizational performance. Yet, increasing challenges in the workplace, including downsizing, layoffs, and job insecurity, can erode employees' sense of purpose and meaning.

Shape-preserving properties of a new family of generalized Bernstein operators

Journal of Inequalities and Applications, 2018
In this paper, we introduce a new family of generalized Bernstein operators based on q integers, called (α,q) $(\alpha,q)$-Bernstein operators, denoted by Tn,q,α(f) $T_{n,q,\alpha}(f)$. We investigate a Kovovkin-type approximation theorem, and obtain the
