Bivariate Chlodowsky-Stancu Variant of (p,q)-Bernstein-Schurer Operators
Journal of Function Spaces, 2019 In this study, it is proposed to define bivariate Chlodowsky variant of (p,q)-Bernstein-Stancu-Schurer operators. Therefore, Korovkin-type approximation theorems and the error of approximation by using full modulus of continuity are presented.

Statistical Approximation of q-Bernstein-Schurer-Stancu-Kantorovich Operators
Journal of Applied Mathematics, 2014 We introduce two kinds of Kantorovich-type q-Bernstein-Schurer-Stancu operators. We first estimate moments of q-Bernstein-Schurer-Stancu-Kantorovich operators. We also establish the statistical approximation properties of these operators. Furthermore, we

Variational approaches to quantum impurities: from the Fr\"{o}hlich polaron to the angulon [PDF]
, 2018 Problems involving quantum impurities, in which one or a few particles are interacting with a macroscopic environment, represent a pervasive paradigm, spanning across atomic, molecular, and condensed-matter physics.

A new complex generalized Bernstein-Schurer operator [PDF]
Carpathian Journal of Mathematics, 2021 "In this paper, we consider the complex form of a new generalization of Bernstein-Schurer operators. We obtain some quantitative upper estimates for the approximation of these operators attached to analytic functions. Moreover, we prove that these operators preserve some properties of the original function such as univalence, starlikeness, convexity ...

Bivariate Bernstein–Schurer–Stancu type GBS operators in ( p , q ) $(p,q)$ -analogue
Advances in Difference Equations, 2020 The purpose of this paper is to construct a ( p , q ) $(p,q)$ -analogue of Bernstein–Schurer–Stancu type GBS (generalized Boolean sum) operators for approximating B-continuous and B-differentiable functions.

American Journal of Political Science, EarlyView.Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of

Journal of Inequalities and Applications, 2019 The current paper deals with a modified form of the Baskakov–Schurer–Szasz–Stancu operators which preserve e−2ax $e^{-2ax}$ for a>0 $a>0$. The uniform convergence of the modified operators is shown.

Contact Dermatitis, EarlyView.ABSTRACT Numerous preventive measures for occupational contact dermatitis (OCD) have been evaluated, but their effectiveness varies, suggesting that contextual factors and corresponding implementation strategies are important. This scoping review aimed to identify preventive interventions for OCD and explore their implementation strategies and outcomes.
