Higher order Kantorovich-type Szász–Mirakjan operators

open access: yesJournal of Inequalities and Applications, 2022
In this paper, we define new higher order Kantorovich-type Szász–Mirakjan operators, we give some approximation properties of these operators in terms of various moduli of continuity. We prove a local approximation theorem, a Korovkin-type theorem, and a

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Approximation Properties of Certain Summation Integral Type Operators

open access: yesDemonstratio Mathematica, 2015
In the present paper, we study approximation properties of a family of linear positive operators and establish direct results, asymptotic formula, rate of convergence, weighted approximation theorem, inverse theorem and better approximation for this ...

On approximation properties of a new construction of Baskakov operators

open access: yesAdvances in Difference Equations, 2021
The purpose of this research is to construct sequences of Baskakov operators such that their construction consists of a function σ by use of two function sequences, ξ n $\xi _{n} $ and η n $\eta _{n} $ .

Approximation properties of modified Jain-Gamma operators

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2021
In the present paper, we study some approximation properties of a modified Jain-Gamma operator. Using Korovkin type theorem, we first give approximation properties of such operator.

Universal approximation by regular weighted means [PDF]

open access: yesPacific Journal of Mathematics, 1985
In this paper we shall improve upon the results by \textit{K. Faulstich}, \textit{W. Luh} and \textit{L. Tomm} [Manuscr. Math. 36, 309-321 (1981; Zbl 0479.30023)] by (i) considering power series representing other meromorphic functions f, (ii) using a regular weighted means method D to obtain the overconvergence property and (iii) showing that D has a ...

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

open access: yesMolecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Approximation by Certain Linear Positive Operators of Two Variables

open access: yesAbstract and Applied Analysis, 2014
We introduce positive linear operators which are combined with the Chlodowsky and Szász type operators and study some approximation properties of these operators in the space of continuous functions of two variables on a compact set. The convergence rate
