Best proximity point results for generalization of ̌–̌ proximal contractive mapping in fuzzy banach spaces [PDF]
, 2022 The best proximity point is a generalization of a fixed point that is beneficial when the contraction map is not a self-map. On other hand, best approximation theorems provide an approximate solution to the fixed-point equation Tҳ = ҳ.

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

φ-Best proximity point theorems and applications to variational inequality problems
, 2017 The main concern of this study is to introduce the notion of φ-best proximity points and establish the existence and uniqueness of φ-best proximity point for non-self mappings satisfying (F,φ)-proximal and (F,φ)-weak proximal contraction conditions in ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Existence of coupled coincidence best proximity point [PDF]
Surveys in Mathematics and its ApplicationsThis work of optimality is engaged with couple coincidence best proximity point. We have developed some optimal results where control functions and non-linear weak inequalities are evident. Further using our results, we establish some fixed point results.

Best Proximity Point Results on Strong b-Metric Spaces
Journal of New Theory, 2021 In the present paper, we prove the two best proximity point results on strong b-metric spaces with coefficient λ by introducing two new concepts which are named as BW b-contraction and proximal BW b-contraction.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Common best proximity point theorems for certain types of mappings
summary:Let $S$ and $T$ be two single-valued non-self-mappings from a nonempty set $\mathcal {P}$ to another nonempty set $\mathcal {Q}$. As they are non-self-mappings, the equations $Sx=x$ and $Tx=x$ do not have a common solution.

Best proximity points in ℱ-metric spaces with applications
Demonstratio Mathematica, 2023 The aim of this article is to introduce α\alpha -ψ\psi -proximal contraction in the setting of ℱ-metric space and prove the existence of best proximity points for these contractions.
