Non-Unique Fixed Point Results in Extended B-Metric Space

Mathematics, 2018
In this paper, we investigate the existence of fixed points that are not necessarily unique in the setting of extended b-metric space. We state some examples to illustrate our results.

New Hybrid Contractions on b-Metric Spaces

Mathematics, 2019
In this manuscript, we introduce the notion of b-hybrid contraction in the setting of b-metric space. We investigate the existence and uniqueness of a fixed point for this contraction.

Generalization of Fixed Point Theorem for φ- Contraction Mapping of a Fuzzy b- Metric Space

Ibn Al-Haitham Journal for Pure and Applied Sciences
Let (X,W,T) be a fuzzy b- metric space, where X is a non-empty set, W is a fuzzy set on X×X×(0,∞) to [0,1], and T is a continuous t-norm, and let a function φ:[0,1]→[0,1] satisfies the following conditions: The function φ is strictly decreasing and ...

Fixed Point and Common Fixed Point Theorems on Ordered Cone b-Metric Spaces

Abstract and Applied Analysis, 2013
The concept of a cone b-metric space has been introduced recently as a generalization of a b-metric space and a cone metric space in 2011. The aim of this paper is to establish some fixed point and common fixed point theorems on ordered cone b-metric ...

Ordered Sp $S_{p}$-metric spaces and some fixed point theorems for contractive mappings with application to periodic boundary value problems

Fixed Point Theory and Applications, 2019
In this paper, we introduce the structure of Sp $S_{p}$-metric spaces as a generalization of both S-metric and Sb $S_{b}$-metric spaces. Also, we present the notions of S̃-contractive mappings in the setup of ordered Sp $S_{p}$-metric spaces and ...

Best proximity for proximal operators on $b$-metric spaces

Turkish Journal of Mathematics, 2023
The paper presents existence results of $(\phi,\varphi)$ best proximity points for operators that fulfill implicit type inequalities. Classes of mappings endowed with continuity, monotone or monotone-type properties, and which additionally satisfy some adequate inequalities are studied from this point of view. Applications of our results are given with

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
