A Sharp Threshold for a Random Version of Sperner's Theorem

open access: yesRandom Structures &Algorithms, Volume 66, Issue 1, January 2025.
ABSTRACT The Boolean lattice đ’«(n) consists of all subsets of [n]={1,
,n}$$ \left[n\right]=\left\{1,\dots, n\right\} $$ partially ordered under the containment relation. Sperner's Theorem states that the largest antichain of the Boolean lattice is given by a middle layer: the collection of all sets of size n/2$$ \left\lfloor n/2\right\rfloor $$, or also,

Some Novel Fixed‐Point Results in Neutrosophic Soft Metric Space With Application in Decision‐Making to Select the Optimal Adsorbent

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this research paper, the concepts of compatible maps and maps of type α¯ and (ÎČÂŻ) within the framework of neutrosophic soft metric spaces (NSMS) are established. The interconnections between α¯‐ and (ÎČÂŻ)‐type maps are also clarified. Additionally, the notions of R‐weakly commuting and weakly commuting mappings in NSMS are introduced. A proof for the

Refractive Accuracy of a Novel Swept‐Source OCT in Patients With Short and Long Eyes

open access: yesJournal of Ophthalmology, Volume 2025, Issue 1, 2025.
Purpose: To analyze the refractive accuracy of a novel swept‐source optical coherence biometer (SS‐OCT), that uses individual refractive indices to measure axial length, in short and long eyes implanted with monofocal intraocular lenses (IOLs). Methods: This retrospective comparative study considered eyes with short axial length (AL) (< 22.5 mm) or ...

A deficit story in motion: How marginalized youngsters are defined out of the educational game before they enter school

open access: yesJournal of Social Issues, Volume 80, Issue 4, Page 1218-1237, December 2024.
Abstract This paper offers a case study of the Life History of the Word Gap (WG) Story, the most prominent deficit discourse of the contemporary era. Mindful of mounting critiques of deficit thinking and informed by Bakhtinian theory, we seek to understand the Story's ascendance by interrogating its evolving historical context.

Efficient numerical approximations for a nonconservative nonlinear Schrödinger equation appearing in wind‐forced ocean waves

open access: yesStudies in Applied Mathematics, Volume 153, Issue 4, November 2024.
Abstract We consider a nonconservative nonlinear Schrödinger equation (NCNLS) with time‐dependent coefficients, inspired by a water waves problem. This problem does not have mass or energy conservation, but instead mass and energy change in time under explicit balance laws.

Fatigue assessment of cord rubber composite air spring bellows based on specimen testing and numerical analysis

open access: yesJournal of Applied Polymer Science, Volume 141, Issue 37, October 5, 2024.
This paper presents a thorough examination of the fatigue performance of cord rubber composites. The investigation includes an analysis of component tests and a specially developed methodology for testing representative specimens. Furthermore, a novel approach is employed to study the transferability of small‐scale specimens to the component level for ...

On tame ramification and centers of F$F$‐purity

open access: yesJournal of the London Mathematical Society, Volume 110, Issue 4, October 2024.
Abstract We introduce a notion of tame ramification for general finite covers. When specialized to the separable case, it extends to higher dimensions the classical notion of tame ramification for Dedekind domains and curves and sits nicely in between other notions of tame ramification in arithmetic geometry. However, when applied to the Frobenius map,

The Geach‐Kaplan sentence reconsidered

open access: yesPhilosophy and Phenomenological Research, Volume 109, Issue 1, Page 288-314, July 2024.
Abstract The Geach‐Kaplan sentence is alleged to be an example of a non‐first‐orderizable sentence, and the proof of the alleged non‐first‐orderizability is credited to David Kaplan. However, there is also a widely shared intuition that the Geach‐Kaplan sentence is still first‐orderizable by invoking sets or other extra non‐logical resources.
