A standard operating procedure for King’s ALS clinical staging [PDF]

open access: yesAmyotrophic Lateral Sclerosis and Frontotemporal Degeneration, 2019
Objective: Clinical stages in amyotrophic lateral sclerosis (ALS) can be measured using a simple system based on the number of CNS regions involved and requirement for gastrostomy or noninvasive ventilation (NIV). We aimed to design a standard operating procedure (SOP) to define the standardized use and application of the King’s staging system. Methods:

Approximation of Functions by Dunkl-Type Generalization of Szász-Durrmeyer Operators Based on p,q-Integers

open access: yesJournal of Function Spaces, 2021
In this article, our main purpose is to define the p,q-variant of Szász-Durrmeyer type operators with the help of Dunkl generalization generated by an exponential function.

Weighted almost convergence and related infinite matrices

open access: yesJournal of Inequalities and Applications, 2018
The purpose of this paper is to introduce the notion of weighted almost convergence of a sequence and prove that this sequence endowed with the sup-norm ∥ ⋅ ∥ ∞ ${\Vert \cdot \Vert } _{\infty}$ is a BK-space. We also define the notions of weighted almost

A Dunkl type generalization of Szász operators via post-quantum calculus

open access: yesJournal of Inequalities and Applications, 2018
The object of this paper to construct Dunkl type Szász operators via post-quantum calculus. We obtain some approximation results for these new operators and compute convergence of the operators by using the modulus of continuity.

Sequence spaces M ( ϕ ) $M(\phi)$ and N ( ϕ ) $N(\phi)$ with application in clustering

open access: yesJournal of Inequalities and Applications, 2017
Distance measures play a central role in evolving the clustering technique. Due to the rich mathematical background and natural implementation of l p $l_{p}$ distance measures, researchers were motivated to use them in almost every clustering process ...

King operators which preserve $x^j$

open access: yesConstructive Mathematical Analysis, 2023
We prove the unique existence of the functions $r_n$ $(n=1,2,\ldots )$ on $[0,1]$ such that the corresponding sequence of King operators approximates each continuous function on $[0,1]$ and preserves the functions $e_0(x)=1$ and $e_j(x)=x^j$, where $j\in\{ 2,3,\ldots\}$ is fixed.

Direct and converse theorems for King operators [PDF]

open access: yesActa Universitatis Sapientiae, Mathematica, 2020
Abstract For the sequence of King operators, we establish a direct approximation theorem via the first order Ditzian-Totik modulus of smoothness, and a converse approximation theorem of Berens-Lorentz-type.
