A New Generalized Quasi-Newton Algorithm Based on Structured Diagonal Hessian Approximation for Solving Nonlinear Least-Squares Problems With Application to 3DOF Planar Robot Arm Manipulator

open access: yesIEEE Access, 2022
Many problems in science and engineering can be formulated as nonlinear least-squares (NLS) problems. Thus, the need for efficient algorithms to solve these problems can not be overemphasized.

Fractional order mathematical modeling of typhoid fever disease

open access: yesResults in Physics, 2022
This manuscript is devoted to focusing on the modeling and numerical solution of the dynamical model of Typhoid Fever. We use the Atangana–Baleanu operator with the Mittag–Leffler function in Caputo sense to study the behavior of the model.

On Essential Fixed Points [PDF]

open access: yesProceedings of the American Mathematical Society, 1959
Wenn jede stetige Abbildung des kompakten Hausdorffschen Raumes \(X\) in sich wenigstens einen Fixpunkt hat, so ist \(p \in X\) wesentlicher Fixpunkt von \(f: X \rightarrow p\). [\glqq Wesentlich\grqq{} bedeutet: Zu jeder Umgebung \(U\) von \(p\) gibt es in \(X^X\) (kompakt-offen topologisiert) eine Umgebung \(N\) von \(f\), so daß jedes \(g \in N ...

Convergence theorems for monotone vector field inclusions and minimization problems in Hadamard spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2023
This article analyses two schemes: Mann-type and viscosity-type proximal point algorithms. Using these schemes, we establish Δ-convergence and strong convergence theorems for finding a common solution of monotone vector field inclusion problems, a ...

Unique fixed points vs. least fixed points

open access: yesTheoretical Computer Science, 1980
AbstractThe aim of this paper is to compare two approaches to the semantics of programming languages: the least fixed point approach, and the unique fixed point approach. Briefly speaking, we investigate here the problem of existence of extensions of algebras with the unique fixed point property to ordered algebras with the least fixed point property ...

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

On p-Common Best Proximity Point Results for S-Weakly Contraction in Complete Metric Spaces

open access: yesMathematics, 2018
In this work, we introduced new notions of a new contraction named S -weakly contraction; after that, we obtained the p-common best proximity point results for different types of contractions in the setting of complete metric spaces by using weak
