PLOS ONE, 2023 Introduction Overcrowding in the emergency departments (ED) is linked to adverse clinical outcomes, a negative impact on patient safety, patient satisfaction, and physician efficiency. We aimed to design a medical admission prediction scoring system based on readily available clinical data during ED presentation.

Periodic Points of Weaker Meir-Keeler Contractive Mappings on Generalized Quasimetric Spaces
Abstract and Applied Analysis, 2014 By using the weaker Meir-Keeler function ϕ and the triangular α-admissible mapping α, we introduce the notion of (α-ϕ)-weaker Meir-Keeler contractive mappings and prove a theorem which assures the existence of a periodic point for these mappings on ...

Abstract and Applied Analysis, 2014 We investigate the existence of a fixed point of certain contractive multivalued mappings of integral type by using the admissible mapping. Our results generalize the several results on the topic in the literature involving Branciari, and Feng and Liu ...

A different approach to complex valued G b $G_{b}$ -metric spaces
Advances in Difference Equations, 2020 In this work, we introduce a generalized fixed point theorem using a complex C-class function as a new tool in complex valued G b $G_{b}$ -metric spaces.

Generalized contractions with triangular α-orbital admissible mapping on Branciari metric spaces
Journal of Inequalities and Applications, 2016 The purpose of this paper is to generalize fixed point theorems introduced by Jleli et al. (J. Inequal. Appl. 2014:38, 2014) by using the concept of triangular α-orbital admissible mappings established in Popescu (Fixed Point Theory Appl. 2014:190, 2014).

Fixed points of multivalued mappings in metric spaces [PDF]
Surveys in Mathematics and its Applications, 2019 Admissibility of mappings are introduced to create conditions to minimally restrict various contractive conditions on pairs of points from a metric space in order to ensure fixed point property of the respective contractions.

EIGENVALUES OF COUNTABLY CONDENSING ADMISSIBLE MAPS
Journal of the Korean Mathematical Society, 2005 The existence of a positive eigenvalue for countably condensing admissible (in the sense of L.~Górniewicz) multivalued mappings in Fréchet spaces is established. An application of the obtained results to the generalized fixed point problem for admissible mappings is presented.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Walkwise and admissible mappings between digraphs
Discrete Mathematics, 1974 AbstractWe define two classes of mappings, between digraphs, which are closely related to homomorphisms and pathwise homomorphisms of finite automata. We show that the cycle rank cannot increase under mappings of these types, derive various decomposition properties, and then relate these mappings to homomorphisms of digraphs.
