A Unique Common Coupled Fixed Point Theorem for Four Maps in Partial b-Metric-Like Spaces

open access: yesSultan Qaboos University Journal for Science, 2015
We prove the existence of a unique common coupled fixed point theorem for four mappings satisfying a general contractive condition on partial b-metric-like spaces. We also give an example to illustrate our main theorem.

Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

open access: yesAdvanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

The Use of Multivariate Data Analysis (HCA and PCA) to Characterize Ashes from Biomass Combustion

open access: yesEnergies, 2021
The content of heavy metals Cd, Cr, Cu, Fe, Ni, Pb and Zn in ash samples from miscanthus, oak, pine, sunflower husk, wheat straw, and willow ashes burned at 500, 600, 700, 800, 900, and 1000 °C, respectively, was determined.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Completion of a Dislocated Metric Space

open access: yesAbstract and Applied Analysis, 2015
We provide a construction for the completion of a dislocated metric space (abbreviated d-metric space); we also prove that the completion of the metric associated with a d-metric coincides with the metric associated with the completion of the d-metric.

Unveiling Bias: The Impact of Male Rape Myths and Stereotypes on Juror Verdicts in Male‐on‐Male Rape Trials

open access: yesBehavioral Sciences &the Law, Volume 44, Issue 3, Page 407-424, May/June 2026.
ABSTRACT This study examined how male rape myths, racial/ethnicity biases, and sexuality stereotypes influence verdicts in male‐on‐male rape trials—an area that is currently under‐researched. A sample of 463 participants read a mock rape trial, where both the defendant and complainant were male, with defendant ethnicity (White, Black, Asian) and ...

Existence and Unique Coupled Solution in Sb-Metric Spaces by Rational Contraction with Application

open access: yesMathematics, 2019
In this paper, we prove a unique common coupled fixed point theorem for two pairs of w-compatible mappings in S b -metric spaces. We also furnish an example to support our main result.

Related Results to Hybrid Pair of Mappings and Applications in Bipolar Metric Spaces

open access: yesJournal of Mathematics, 2019
In this paper, we introduce the concept of multivalued contraction mappings in partially ordered bipolar metric spaces and establish the existence of unique coupled fixed point results for multivalued contractive mapping by using mixed monotone property ...

Grafting Nanolayers of Ni and Co Catalysts Around the Edges of Hierarchical Zeolite 13X by Leveraging the Crystal's Defects for CO2 Methanation

open access: yesCarbon Energy, EarlyView.
The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.
