Exercise Testing And Training For Individuals With Cystic Fibrosis, Najlaa Zayed Alotaibi

ETDs from 2020-2029

Cystic fibrosis (CF) is a progressive genetic disease that impacts multiple systems (e.g., respiratory system). Hence, routine cardiopulmonary exercise testing (CPET) is recommended to track the disease progression in people with CF. Besides the benefits of exercise testing, exercise training is also beneficial for long-term wellness. It is recommended that people with CF engage in at least 30–60 minutes of aerobic exercise 3 days a week. However, despite the significance of exercise testing and training for people with CF, CPET and exercise training are underutilized in international CF centers. According to the literature, the majority of international CF centers use …

Analysis Of Activated Carbon Fiber (Acf) As Particulate Filtration And Volatile Organic Compound (Voc) Media For The Development Of A Dual-Air Purifying Facepiece Respirator, Brie Mcmahan

ETDs from 2020-2029

Exposure to particulate matter (PM) and volatile organic compounds (VOCs) in occupational or public settings poses adverse health outcomes such as respiratory, cardiovascular, reproductive, neurological, carcinogenic morbidity and mortality. Many occupational settings expose workers to PM and VOC concurrently, yet most commercially available respirators are designed to address either particulates or vapors alone. This includes air-purifying respirators (APRs), powered air-purifying respirators (PAPRs), and filtering facepiece respirators (FFRs) with nuisance-level vapor protection, often limited by bulk, discomfort, high pressure drop, and misuse. We identified a need for alternative dual-exposure media and a respiratory protection device that is lighter, and more comfortable …

Understanding Mobility Limitations And Public Transportation Accessibility For People With Disabilities, Jada Meria Stringer

ETDs from 2020-2029

Mobility for people with disabilities (PWDs) depends on both the availability of transportation and public services and the accessibility of these systems. The presence of public transportation systems does not ensure usability. Vehicles, infrastructure, and the built environment must be designed to accommodate diverse physical, sensory, cognitive, and other needs. PWDs must also be able to navigate public buildings and surrounding spaces safely and comfortably. This thesis examines mobility limitations for PWDs in India and the United States, focusing on accessibility along the full mobility chain. A review of existing literature provides context on accessibility policies, design standards, and the …

Untold Journeys: A Case Study Of Attrition In Alabama’S Public School Teaching Workforce, Jessica Claborn Rose

ETDs from 2020-2029

This exploratory multiple-case study investigates the crisis of teacher attrition among early childhood and elementary education graduates from Alabama-based teacher education programs (TEPs) who either avoided public-school teaching or left the profession within three years. The research, guided by Bandura’s social cognitive theory (SCT) and Maslow’s human motivation theory, utilized a qualitative design involving individual interviews with ten teacher leavers (TLs), and five TEP faculty members. The findings reveal that attrition is a multi-faceted crisis rooted in systemic failures, coalescing around two overarching factors: effectiveness of support systems and a collection of barriers. Consistent with SCT, low self-efficacy, resulting from …

Biomineralization Of Low Temperature Plasma(Ltp) Modified Polymeric Biomaterials And Scaffolds, John Patrick Bradford

ETDs from 2020-2029

Bio-integration, specifically osseo-integration of bone implants and scaffolds, are vital for the success of implants and bone tissue engineering (BTE). Calcification can be defined as the deposition of calcium compounds as either calcium phosphate(CaP) minerals consisting of hydroxyapatite(HAP) or CaP salts. The significance of the variety of phases of CaP is that mature bone matrix is composed of 65% CaP mineral. Many investigators have attempted to model the natural matrix by producing materials containing calcium phosphate in both amorphous CaP or in the more crystalline HAP form, with biomaterials (both synthetic and biological). Biomimetic CaP formation is a sign of …

Quantum Technologies, Part One: Focusing A Bit Upon Realities, James Giordano

Strategic Insights

This commentary examines the current realities of quantum technologies and their implications for national security and defense. While quantum systems are often described as revolutionary, their practical military impact remains uneven and frequently overstated. This analysis reviews three key domains—quantum computing, sensing, and communications, and explains where these technologies currently outperform classical systems and where significant technical limitations remain. In particular, quantum computing is still in a “noisy, intermediate-scale” stage, meaning most applications remain experimental and dependent on advances in error correction, algorithms, and hardware. Understanding both the promise and limitations of quantum technologies is essential for shaping realistic defense …

Characterizing The West Antarctic Ice Sheet Dynamics During Marine Isotope Stage 5 Using Analysis Of Iceberg Rafted Debris, Madelyn Krischer, Natalia Freedman, Trevor Williams

Making Waves REU

• The West Antarctic Ice Sheet (WAIS) is vulnerable to ocean warming because much of the ice rests on bedrock below sea level. Studying past warm periods helps improve our understanding of WAIS response to future climate change (Hopkins et al., 2024).

Investigation Of The Phase Space Of Tungsten Oxides Nanostructures Via Resistive Hot Wire Oxidation For Efficient Electrochemical Energy Storage And Conversion Applications., Krishna Kc

Theses and Dissertations

The synthesis of tungsten oxide (WO3−δ, 0 ≤ δ ≤ 1) nanostructures with controlled phase and morphology remains a significant challenge, particularly for applications in energy conversion and storage. This dissertation presents an eco-friendly and time-efficient method for synthesizing tungsten oxide nanostructures with tailored stoichiometry and crystal phases through the Resistive Hot Wire Oxidation (RHWO) technique. In this method, a tungsten wire is heated via resistive heating in an oxygen environment, and by precisely controlling the growth conditions, we successfully synthesized WO2.72, WO2.76, WO2.80, WO2.83, WO2.90, and WO2.98 phases with controlled morphologies using simple instrumentation. This approach eliminates the need …

Hybrid Quantum-Classical Optimization Of The Resource Scheduling Problem, Tyler Christeson, Md Habib Ullah, Ali Arabnya, Amin Khodaei, Rui Fan

Electrical and Computer Engineering: Faculty Scholarship

Resource scheduling is critical in many industries, especially in power systems where the Unit Commitment (UC) problem determines the on/off status and output levels of generators under physical and economic constraints. Traditional exact methods, such as Branch-and-Bound, Branch-and-Cut, dynamic programming and mixed-integer linear programming (MILP), remain the backbone of UC solution techniques, but they often rely on linear approximations or exhaustive search, leading to high computational burdens as system size grows. Metaheuristic approaches, such as genetic algorithms, particle swarm optimization, and other evolutionary methods, have been explored to mitigate this complexity; however, they typically lack optimality guarantees, exhibit sensitivity to …

Bankruptcy Judging After Williamson, Vincent S.J. Buccola

BYU Law Review

This Essay asks how bankruptcy judges ought to orient their substantial, statutory discretion in business reorganization cases. The motivating observation is that bankruptcy law enacts a kind of forced integration of productive assets. To shed light on the contemporary problems that bankruptcy judges face, I thus look to two classic approaches to the economic theory of the firm—from Oliver Williamson and from Oliver Hart. I conclude that nonjudicial institutions have largely surmounted the problems to which their theories point, leaving a different, and probably narrower, set of issues to worry about. Bankruptcy judges who have a notion that their job …

A Bovine Cell Line Resistant To Japanese Encephalitis Virus Entry But Permissive To Post-Entry Replication, Sang-Im Yun, Young-Min Lee

Animal, Dairy, and Veterinary Science Faculty Publications

Japanese encephalitis virus (JEV) is a mosquito-borne zoonotic orthoflavivirus that poses a significant global health threat. It causes severe neuroinflammatory disease in humans and reproductive failure in swine. Because of the broad host range and cell tropism of JEV, identifying animal cell lines resistant to infection has been a persistent challenge. In this study, we demonstrate that Madin–Darby bovine kidney (MDBK) cells are resistant to JEV infection yet remain fully permissive to viral replication when transfected with viral genomic RNA. Using immunoblotting, immunofluorescence, and flow cytometry, we show that MDBK cells, unlike the highly susceptible baby hamster kidney (BHK-21) cells …

Biomarkers Of Response To Neoadjuvant Palbociclib Plus Anastrozole In Endocrine-Resistant Estrogen Receptor-Positive/Her2-Negative Breast Cancer: A Phase 2 Trial, Tim Kong, Alex Mabry, Maureen Highkin, Jeremy Hoog, Zhanfang Guo, Adrian Gonzales-Gonzales, Shana Thomas, Yingduo Song, Feng Gao, Mateusz Opyrchal, Lindsay Peterson, Foluso Ademuyiwa, Julie Margenthaler, Rebecca Aft, Katherine Glover-Collins, Leslie Nehring, Yu Tao, Souzan Sanati, Ian S Hagemann, Fouad Boulos, Li Ding, Stephen T Oh, Ron Bose, Jason D Weber, Jingqin Luo, Cynthia X Ma, Et Al.

2020-Current year OA Pubs

CDK4/6 inhibitors (CDK4/6i) improve outcomes for estrogen receptor (ER) positive/HER2-negative breast cancers (BCs), yet intrinsic and acquired resistance exist. Here, we evaluated anastrozole in combination with palbociclib (ANA/PAL) in the NeoPalAna Endocrine-Resistant cohort (NCT01723774). Thirty-four patients with clinical stage II/III ER + /HER2- BCs resistant to standard neoadjuvant endocrine therapy (on-treatment Ki67 > 10%) received neoadjuvant ANA/PAL, with serial biopsies analyzed. The primary endpoint, complete cell cycle arrest (CCCA; Ki67

Recurrence Of Locally Perturbed Random Walks With Long Jumps, Tamer Oraby, András Telcs

School of Mathematical & Statistical Sciences Faculty Publications

We study the effect of local perturbations on the recurrence of random walks with long jumps. Such walks serve as discrete models for infinite-horizon Lorentz processes, in which a particle can take arbitrarily long steps in specific directions. Motivated by a question of Sinai in the finite-horizon case and its extension by Szász to the infinite-horizon setting, we give recurrence and transience criteria for long-jump walks on Z2 and certain classes of graphs, and we prove that local perturbations in a bounded region do not change the recurrence property. Our proofs combine the Markov chain approach with the electrical network …

Beyond The Rash: Cutaneous Peripheral T-Cell Lymphoma As A Diagnostic Pitfall In Primary Care, Jared Hensley, Aura Calderon, Blake Martin, Cristina Kochi, Andres Suarez Parraga

School of Medicine Publications

Cutaneous manifestations of T-cell lymphomas may resemble common dermatologic or infectious conditions, increasing the risk of delayed recognition. We report a 78-year-old woman with known peripheral T-cell lymphoma (PTCL) who presented with a rapidly progressive, diffuse erythematous rash accompanied by cervical lymphadenopathy. Initial evaluation prioritized more common etiologies; however, inpatient medicine broadened the differential diagnosis, prompting early hematology and oncology consultation. Contrast-enhanced CT of the neck demonstrated multiple enlarged, partially necrotic left cervical lymph nodes consistent with disease progression. After multidisciplinary discussions and consideration of prognosis, the patient elected palliative-focused management with oncology follow-up. This case underscores the importance of …

Cxcr4-Targeted Theranostics In Non-Hodgkin Lymphoma: Present Evidence And Future Directions, Marcus Yoakam, Uma A. Obalapuram, Kameron Hahn, Samir Dalia

Student Publications

Non-Hodgkin lymphoma (NHL) is a biologically heterogeneous group of lymphoid malignancies with variable clinical outcomes despite advances in chemotherapy, immunotherapy, and cellular therapies. The C–X–C chemokine receptor 4 (CXCR4)/ C–X–C motif chemokine ligand 12 (CXCL12) axis plays a central role in lymphocyte trafficking, survival, and tumor microenvironment interactions. It is frequently dysregulated in NHL, making it an attractive target for precision oncology. CXCR4- directed theranostics combines molecular imaging and targeted radionuclide therapy, enabling real-time assessment of receptor expression, patient stratification, and personalized treatment delivery. Diagnostic positron emission tomography imaging using ⁶⁸Ga-pentixafor reliably visualizes CXCR4-expressing disease, while therapeutic agents, such …

A Constructive-Engaging Analysis Of Descarrtes (European) And Oyeshile (African) On Personhood, Olanrewaju Shitta-Bey

Comparative Philosophy

An examination of the nature of the human person provides a crucial foundation for understanding human life and identity. Conceptions of personhood have far-reaching implications beyond philosophy, influencing politics, ethics, religion, and epistemology. Beliefs about what constitutes a person shapes theories of rights, responsibility, and justice; moral views on duty and accountability; religious understandings of the soul and the afterlife; and epistemological reflections on the sources and limits of knowledge. Inquiry into human nature is therefore not merely abstract, but central to understanding social organization and individual conduct. This paper examines two influential accounts of human nature drawn from distinct …

A Cross-System Analysis Of Structural Commensurability Between Axiomatic Foundations Of Set Theory (Zfc) And The Principles Of Transcendent Wisdom, Mohammadjavad Maarefvand

Comparative Philosophy

Building on observed similarities in uniqueness proofs for the empty set and the Necessary Existent (Wājib al-Wujūd), this study engages the meta-methodological issue of cross-system commensurability. It identifies four instances of structural commensurability between Zermelo-Fraenkel set theory with Choice (ZFC) and Mulla Sadra's Transcendent Wisdom (Ḥikmat al-Muta'āliyah). First, identity principles: the Axiom of Extensionality provides a formal operational criterion analogous to the philosophical principle of identity through absence of distinguishing features. Second, multiplicity mechanisms: ZFC's constructor axioms (bottom-up construction) and emanation principles (top-down explanation) address analogous problems with inverse orientations. Third, transcending limitation: the Axiom of Infinity ensuring quantitative extensional …

A Critique Of Ziporyn’S Interpretation Of Early Chinese Thought: From The Constructive-Engagement Vantage Point, Xiaoqiao Liu

Comparative Philosophy

Sameness and difference are among the most fundamental and yet most tension-laden categories in philosophy, bearing directly on the conditions under which judgment, classification, and meaning become possible. This article critically reconstructs and compares two influential but methodologically divergent approaches to this issue in contemporary comparative philosophy. One is Brook Ziporyn’s idea of coherence, which seeks to articulate a non-substantialist metaphysics as a response to tensions internal to the Western metaphysical tradition. The other is Bo Mou’s enhanced account of relative identity, which revises both absolute and modern relative identity theories through a bottom-up, semantically grounded framework oriented toward cross-tradition …

Father Knows Best? Not Here: Metaphors Of Kinship And Kingship In Haudenosaunee, Aristotelian, And Confucian Political Thought, Ian Kalman

Comparative Philosophy

The notion that the organization of large-scale social structures are rooted in domestic ones has a longstanding history in both Chinese and Greek classical political philosophy. Aristotle and Confucius independently reasoned that a good family, one with a strong father, mapped onto a good state, one with a strong king - though they differed on the details. While there is a strong literature juxtaposing these two titans, less attention has been paid to how their ideas compare with other philosophical traditions. This article provides an anthropological intervention to the comparative study of Confucius and Aristotle – while both autonomously argued …

The Coherence Of Navayāna Pragmatism: Ambedkar And The Pragmatist Reconstruction Of Buddhist Philosophy, Danish Hamid

Comparative Philosophy

This paper examines the philosophical coherence of B.R. Ambedkar’s reconstruction of his (Navayāna) Buddhism in relation to John Dewey’s pragmatism. Building on Scott Stroud’s reading of Ambedkar as a Deweyan Pragmatist (2017, 2023), it argues that Dewey’s evolutionary naturalism, his conception of growth, and pragmatic redefinition of concepts provide Ambedkar with the methodological tools for a naturalistic and socially reconstructive reinterpretation of Buddhist doctrines such as anicca (impermanence), dhamma (Buddha’s teaching), nirvāṇa (enlightenment), karuna (compassion), etc. Ambedkar transforms impermanence from a metaphysics of flux into an ethics of progressive growth, and recasts dhamma as a social morality grounded in fraternity …

Effects Of Infused Instruction On Graduate Students’ Knowledge, Self-Perceptions, And Misconceptions Of African American English Dialect, Virginia L. Dubasik, Tim Brackenbury, Jasmine I. Wilson

Teaching and Learning in Communication Sciences & Disorders

Despite guidelines and requirements for training programs in communication sciences and disorders (CSD), pre-service and practicing speech-language pathologists report feeling under-prepared to work with speakers of Nonmainstream American English (NMAE) dialects such as African American English (AAE; Latimer-Hearn, 2020). The current study explored explicit instruction of the phonological and syntactic characteristics of AAE via infused instruction with speech-language pathology graduate students. Participants were 43 first- and second-year students in a CSD program. At the start of the course, participants completed a pre-instruction survey containing questions regarding demographics, exposure/experiences with AAE, baseline knowledge of AAE characteristics, and misconceptions regarding the dialect. …
