Best proximity point (pair) results via MNC in Busemann convex metric spaces

Applied General Topology, 2022
In this paper, we present a new class of cyclic (noncyclic) α-ψ and β-ψ condensing operators and survey the existence of best proximity points (pairs) as well as coupled best proximity points (pairs) in the setting of reflexive Busemann convex spaces ...

Coupled fixed point and best proximity point results involving simulation functions

Boletim da Sociedade Paranaense de Matemática, 2022
The purpose of this paper is to prove coupled fixed point theorems using simulation functions that extend the results of Kojasteh et al . As an application we prove a coupled best proximity points using simulation functions.

On the existence of coupled best proximity point and best proximity point for Suzuki type alpha^+-theta-proximal multivalued mappings

The Journal of Nonlinear Sciences and Applications, 2017
Summary: Following the study for the best proximity points of the Suzuki type \(\alpha^+\)-\(\theta\)-proximal single-valued mappings given by \textit{N. Hussain} et al. [Fixed Point Theory Appl. 2016, Paper No. 14, 20 p. (2016; Zbl 1347.54085)], we deal with the Suzuki type \(\alpha^+\)-\(\theta\)-proximal multivalued mappings satisfying generalized ...

Coupled best proximity point theorems for α-ψ-proximal contractive multimaps [PDF]

Fixed Point Theory and Applications, 2015
AbstractIn this paper, we establish coupled best proximity point theorems for multivalued mappings. Our results extend some recent results by Ali et al. (Abstr. Appl. Anal. 2014:181598, 2014) as well as other results in the literature. We also give examples to support our main results.

Coupled best proximity point theorems for proximally g-Meir-Keeler type mappings in partially ordered metric spaces [PDF]

Fixed Point Theory and Applications, 2015
AbstractIn this paper we first introduce the notion of proximally g-Meir-Keeler type mappings, then we study the existence and uniqueness of coupled best proximity points for these mappings. This generalization is in line with Edelstein’s generalization of Meir-Keeler type mappings, as well as in line with the recent one used in (Eshaghi Gordji in Math.

Coupled ‎f‎ixed points for a class of non-cyclic contractions in uniformly convex Banach spaces with error estimates [PDF]

Iranian Journal of Numerical Analysis and Optimization
In this paper, we introduce a non-cyclic contraction pair of an ordered pair of mappings. We then deduce the existence and uniqueness of coupled fixed points by associating a non-cyclic contraction with them.

Biomedical research in france and brazil: an analysis of significant differences and ethical issues

Revista Brasileira em Promoção da Saúde, 2016
At first sight, Brazil and France seem pretty distant from one another, but on the map, they are not separated by the Atlantic Ocean, but by the Oyapock River, located between the state of Amapa and French Guiana (French overseas department), creating a ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
