Preliminary study of muscle contraction assessment by NIR spectroscopy [PDF]

, 1998
NIR spectroscopy allows monitoring of muscle oxygenation and perfusion during contraction. The knowledge of modifications of blood characteristics in body tissues has relevant clinical interest. A compact and reliable device, which makes use of two laser

On extended interpolative single and multivalued $F$-contractions

Turkish Journal of Mathematics, 2022
The main objective of this paper is to study an extended interpolative single and multivalued Hardy-Rogers type $F$-contractions in complete metric spaces. We prove some fixed point theorems for such mappings. Further, we give an application to integral equations to verify our main results.

Some fixed point results in complete generalized metric spaces

Karpatsʹkì Matematičnì Publìkacìï, 2018
The Banach contraction principle is the most important result. This principle has many applications and some authors was interested in this principle in various metric spaces as Brianciari.

Fixed Point Results for Multivalued Mapping in $\mathrm{R}$-Metric Space [PDF]

Sahand Communications in Mathematical Analysis, 2023
This paper explores certain fixed point results for multivalued mapping in a metric space endowed with an arbitrary binary relation $\mathrm{R}$, briefly written as $\mathrm{R}$-metric space.

A new approach to multivalued nonlinear weakly Picard operators

Journal of Inequalities and Applications, 2019
The notion of nonlinear (Fs,L) $(\mathcal{F}_{s}, \mathcal{L})$-contractive multivalued operators is initiated and some related fixed point results are considered. We also give an example to show the validity of obtained theoretical results.

Application of some new contractions for existence and uniqueness of differential equations involving Caputo–Fabrizio derivative

Advances in Difference Equations, 2021
In this paper we study fractional initial value problems with Caputo–Fabrizio derivative which involves nonsingular kernel. First we apply α-ℓ-contraction and α-type F-contraction mappings to study the existence and uniqueness of solutions for such ...

A new generalization of $\alpha$-type almost-$F$-contractions and $\alpha$-type $F$-Suzuki contractions in metric spaces and their fixed point theorems

Karpatsʹkì Matematičnì Publìkacìï, 2019
In this paper a new generalization of $\alpha$-type almost-$F$-contractions and an extension of $\alpha$-type $F$-Suzuki contractions are given. Moreover, some new fixed point theorems of them are discussed.

Almost $\alpha$-Hardy-Rogers-$F$-contractions and their applications

Armenian Journal of Mathematics, 2022
The aim of this article is to introduce the notion of almost $\alpha$-Hardy-Rogers-$F$-contractions in the partial metric space and utilize it to establish the existence of a unique fixed point. Some examples are given to demonstrate the validity of our main result. Our results generalize classical and newer results in the literature.
