The XRD patterns confirmed the successful formation of a hexagonal wurtzite …

Evaluation Of Home Loan Candidates Using Energy And Laplacian Energy In Hesitancy Fuzzy Zagreb Matrices, A. Abinaya, G. Deepa

Baghdad Science Journal

A hesitancy fuzzy graph is a type of generalized fuzzy graphs that reflects reluctance or uncertainty in interactions by assigning a variety of potential membership values rather than a single value to each vertex and edge. It offers an adaptable framework for simulating intricate systems with ambiguous, reluctant, or imperfect input. Topological measurements that capture and characterize a graph's structural features are called Zagreb indices, and they are obtained from vertex degrees. Although Zagreb indices and graph energies have been studied for intuitionistic fuzzy graphs, fuzzy graphs, and classical graphs, no work has been done to apply these ideas to …

Approximation In S-Normed Orlicz Spaces, Zainab Abdulmunim Sharba, Hawraa Abbas Almurieb, Samah Alhashemi

Baghdad Science Journal

Orlicz spaces generalize conventional Lebesgue spaces, providing a more flexible framework for analyzing functions. They are essential to functional analysis and related fields, particularly in approximation theory. This paper defines an Orlicz normed space equipped with an S-norm, where S is an outer function that satisfies certain conditions. Introducing norms via the outer function S is a general method that encompasses many cases of norms in Orlicz spaces. The relationship between S-norm and other norms on Orlicz spaces is established through several equivalences. Moreover, moduli of smoothness are of great interest in approximation theory, as they provide criteria …

Digraph And Graph Of Regular Rings With Some Properties, Shahla Moayad Kaleel, Haitham Nashwan Mohammed, Ahmad Mohammed Alghamdi, Ahmed Mohammed Ali, Eman Sultan Almotairi

Baghdad Science Journal

During this century, a new research trend has emerged wherein algebraic concepts are combined with graph theory, such as zero divisors, clean rings, ideals, and regular rings. Continuing this trajectory, the regular ring graph has been studied in two forms: the undirected graph and the directed graph. The vertex set consists of all regular elements in the ring ℜ, denoted by ℜ(ℜ), where the undirected graph is denoted by Γ(ℜ(ℜ)) and the directed graph by Ψ(ℜ(ℜ)). This study focuses on the rings Z_n, where n = q, q², or 2q, and q is a prime number. In …

Potential For Lunar Interior Science By The Gravitational-Wave Detector Lila, Mark P. Panning, Philippe Lognonné, Teviet Creighton, James Trippe, Volker Quetschke, Josipa Majstorović, Karan Jani

Physics & Astronomy Faculty Publications

The laser interferometer lunar antenna (LILA), a concept for measuring sub-Hz gravitational waves on the Moon, would use laser strainmeters to obtain extremely sensitive strain measurements from 1 mHz to 1 Hz. With proposed strain sensitivities, LILA would also be able to measure the normal modes of the Moon from 1–10 mHz at high signal-to-noise ratio. Such measurements would enable significant advances in our understanding of both the spherically symmetric and even 3D deep internal structure of the Moon. Strainmeter measurements may even be able to detect the translational mode of the solid inner core of the Moon at frequencies …

Enhancing Sleep Quality Through Sleep Hygiene Education Among Adults In A Faith-Based Community, Denielle Earle-Thompson

Doctor of Nursing Practice Projects

Background

Adults between 18 and 64 years of age require at least seven hours of sleep per night; however, many adults do not meet this recommendation, contributing to increased risks for chronic disease, impaired functioning, mood disturbances, and reduced quality of life. Poor sleep quality has been associated with weakened immunity, cardiovascular disease, diabetes, obesity, anxiety, depression, and decreased daytime performance. Obtaining adequate, good-quality sleep is essential for maintaining overall health and well-being. In faith-based communities, combining health education with spiritual support may provide a holistic approach that addresses both physical and emotional contributors to poor sleep.

Quasi-Mixing C0-Semigroups And Their Relations With Recurrent C0-Semigroups, Mansooreh Moosapoor, Otmane Benchiheb

Baghdad Science Journal

This article presents and investigates the concept of the quasi-mixing C₀-semigroups. It is proved that the quasi-mixing of an invertible C₀-semigroup is equivalent to the quasi-mixing of its inverse. The quasi-mixing vectors are defined and they are used to prove a sufficient condition for the quasi-mixing. It is established that the quasi-mixing of a C₀-semigroup is equivalent to the quasi-mixing of any of its discretizations. The quasi-mixing of a C₀-semigroup ( T_t )_{t ≥ 0}, as it is demonstrated by this study, implies the quasi-mixing for each operator T …

Dark-Matter-Deficient Twins: Fcc 224 And Fcc 240 As Possible Analogs Of Ngc 1052-Df2 And Df4, Maria Luísa Buzzo, Pieter Van Dokkum, Michael Hilker, Duncan A. Forbes, Aaron J. Romanowsky, Yimeng Tang

Faculty Research, Scholarly, and Creative Activity

The recent “bullet-dwarf” model proposes that high-velocity collisions between dwarf galaxies can produce stellar systems with overluminous globular clusters (GCs) and a deficiency of dark matter, as observed in the NGC 1052 group galaxies NGC 1052-DF2 and NGC 1052-DF4. We present a possible analog system in the outskirts of the Fornax cluster: the ultradiffuse galaxy FCC 224 and its close companion FCC 240. Using deep Very Large Telescope/MUSE integral field spectroscopy, we characterize their stellar populations, internal kinematics, and GC systems to test this formation scenario. Both galaxies exhibit low velocity dispersions. Interpreted with a standard mass estimator at the …

Quantitative Genetic Analysis Of Baboon Facial Variation Challenges A Classic Papionin Trait, A. Thiebaut, C. C. Roseman, Michael Mahaney, Leslea J. Hlusko

Human Genetics Publications

The Linnaean family of monkeys that includes baboons, macaques, and mandrills (among others) is notably characterized by large, extended muzzles that vary in lateral nasal dorsum profile. In paleontological studies, this variation is referred to as the anteorbital drop (AOD). Here, we first devise a method to quantify this phylogenetic character. We then employ quantitative genetic analyses using a MCMCglmm model of facial variation in a captive, pedigreed baboon colony (n = 934), including admixed individuals derived from at least two Papio species, from the Southwest National Primate Research Center to assess the quantitative variation of the AOD, its …

Van Der Waals Interactions Through The Lens Of 2d Materials With Emphasis On Many-Body Effects, Thi Xuan Diem Dang

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the long-standing challenge of accurately and efficiently modeling long-range electron correlations, with a particular focus on van der Waals (vdW) interactions. These interactions play an essential role in predicting the structure, stability, and functionality of molecular systems and condensed matter materials. Although Density Functional Theory (DFT) has become a robust cornerstone of computational materials science, traditional formulations of the theory frequently fail to capture dispersive interactions, leading to significant errors in determining interlayer distances, binding energies, and stacking configurations. These limitations become particularly pronounced in layered materials and vdW heterostructures (HSTs), where weak long-range correlations are sensitive …

Transforming Urban Food Systems: Could Food Democracy And Food Citizenship Be Advanced By Personal And Community Impacts Of Co-Production Processes?, Bramble Gardiner, Mary Hickson, Louise Hunt, Amanda Haslam-Lucas, Barbara Diouri, Joanna Ruminska, Laura Dunn, Yve Ashton, Clare Pettinger

School of Health Professions

For complex challenges like food systems transformation, scholars suggest co-production involving multiple actors including citizens is essential. Additionally, some argue for a transformation towards ‘food democracy’. This vision aims for food system decision making to be shared across diverse actors, and people to move from being consumers to citizens (food citizenship). Urban food policy initiatives are examples of innovation in food democracy and food citizenship, but delivering authentic participation is an ongoing challenge and the impacts on those engaged have rarely been studied. Furthermore, personal transformations are essential for societal transformations and similarly receive minimal focus. The need for development …

Branding, Catalogs, And Institutional Identity: The Libraries Of Edfu And Alexandria In Historical Perspective, Patrick Roughen

Library Philosophy and Practice (e-journal)

This article examines library catalogs as brand artifacts in the context of two ancient libraries: the Library of Alexandria and the library of the Temple of Horus at Edfu, Egypt. Drawing on Pierre Bourdieu’s concept of symbolic capital and brand theory, this research argues that the catalogs of these two institutions functioned as early branding instruments. The Pinakes, the catalog of the Library of Alexandria, projected a brand of universal knowledge and intellectual prestige, and the inscribed wall catalog at Edfu reflected a brand focused on sacred authority and the sustaining of cosmic order (Ma'at).  Together, they illustrate two opposing …

Resistivity reached 81–91% of control; shrinkageremained 8–18% above control. XRD confirmed reduced Ca(OH)2 content with enhanced C–S–H formation; SEM revealed reduced ITZ porosity. …

Using Galex Uv Excess To Search For Metal-Poor Halo Stars, Chase L. Smith, Maxwell Moe, Megan Frank, Raven Cilley, Javier Fregoso, Alexander Gleason, Grace Nelson, Et Al.

Michigan Tech Publications

Metal-poor solar-type stars display a significant reduction in metal-line blanketing at short wavelengths, leading to an excess of near-ultraviolet (NUV) flux compared to their metal-rich counterparts. We utilize Galaxy Evolution Explorer Satellite (GALEX) NUV and Gaia DR3 photometry along with ground-based spectroscopy to establish a correlation between NUV excess and [Fe/H]. We construct a sample of 492 solar-type (F5-G9) halo stars with NUV excess and measured metallicities. We perform our own observations with the KOSMOS spectrograph at Apache Point Observatory’s 3.5 m telescope to measure the abundances of 13 halo stars, 11 of which did not have previous metallicity measurements. …
