Physics-Guided Strategies For Enhancing Neural Networks Trained With Limited Data, Jose Guadalupe Perez Zamora

Open Access Theses & Dissertations

Deep neural networks excel at a wide range of processing tasks across various disciplines. However, the quantity and quality of data significantly impact network performance. In specialized domains, high-quality datasets are often difficult to gather, interpret, and curate for effective learning. Few-shot learning techniques, including transfer learning, data augmentation, and meta-learning, have emerged to address these constraints.

We propose three physics-guided strategies for enhancing neural networks trained with limited data: (1) combining existing models like LSTMs with Physics-Informed Neural Networks through two-branch architectures that merge their outputs, (2) deriving custom physics-informed data augmentation algorithms to expand limited datasets, and (3) …

Analyzing Patterns In Hofstede’S Cultural Dimensions Towards Individual Ai Receptiveness For Affective Experiences, Maggie Yang

Master's Theses

The use of artificial intelligence (AI) has significantly advanced efficient decision-making, with trust in algorithmic decisions shown to vary by cultural upbringing [1]. As AI becomes increasingly embedded in everyday life, it is essential to examine how cultural values affect trust in AI in subjective contexts that extend beyond purely quantitative analysis, like the personal interpretation of art. This work utilizes Hofstede’s cultural dimensions to investigate potential patterns in receptiveness towards AI predictions during art interpretation, providing insight into individual susceptibility to bias in AI-assisted affective analysis.

The study leveraged a cultural dimension survey and a custom Java program connected …

Associations Between Feed Efficiency And Feeding Behavior In Yearling Angus Bulls In A Competitive Environment, Amelia Katz

Master's Theses

Feed efficiency in beef cattle is a complex trait shaped by physiological, behavioral, and social factors that influence how animals access and utilize feed resources. This study examined feed efficiency classification and how it is influenced by feeding behavior, competitive interactions, and bunk approach patterns in yearling Angus bulls housed in a drylot over two years. Bulls were grouped into high and low feed efficiency categories using residual feed intake and feed conversion ratio within pen and year (n = 40 per year; n = 40 per treatment). Continuous electronic monitoring quantified feeder visitation, feeding duration, intake, and rate. A …

Nene Leakes As A Modern Medea, Jazzlyn L. White

Electronic Theses, Projects, and Dissertations

This paper examines how The Real Housewives of Atlanta functions as a modern form of Greek tragedy through its portrayal of Nene Leakes, whose rise and fall within the Bravo franchise mirrors the tragic arc of Euripides’ Medea. Both Medea and Leakes represent women who defy the systems that once empowered them Medea through her rebellion against patriarchal and familial structures, and Leakes through her public confrontation with the television industry that made her a star. By analyzing these two figures through rhetorical, feminist, and media studies frameworks, this paper argues that reality television operates as a contemporary stage …

Synthesis Of Phenyl-Substituted Zinc Dipyrrin Photosensitizer For Carbon Dioxide Reduction, Stephen Ankomah

Electronic Theses and Dissertations

The release of CO₂ from fossil fuel combustion drives the need for its conversion into more sustainable options like CO and CH₄ via photocatalytic reduction. This process requires a catalyst, sensitizer, and electron donor. Zinc dipyrrin-based complexes are promising photosensitizers, offering an alternative to expensive, rare-metal-based systems. Most first-row transition metal dipyrrin compounds have short excited-state lifetimes due to rapid nonradiative decay, but Zn(II) dipyrrin complexes stand out. With a d¹⁰ configuration, they lack deactivating ligand field states and can access long-lived triplet states through a charge-separated intermediate. A phenyl-substituted Zn(II) dipyrrin complex was synthesized and studied using NMR to …

Divergent Responses Of Branched-Chain And Straight-Chain Lipid Membranes To Butanol Stress Revealed By All-Atom Molecular Dynamics Simulations, Joshua Olaf Aggrey

Electronic Theses and Dissertations

Membrane integrity under chemical stress is critical to cellular survival and industrial microbial bioproduction, yet the molecular basis of bilayer resilience remains poorly understood. Using all-atom molecular dynamics simulation, we compare the effect of increasing concentrations of 1‑butanol on membranes composed of straight-chain (1,2-dipalmitoyl-sn-glycero-3-phosphocholine, DPPC) and branched-chain (1-anteiso-palmitoyl-2-palmitoyl-sn-glycero-3-phosphocholine, APPC) lipids, which differ in the point of attachment of a single methyl group. In the absence of butanol, both membranes exhibit well-ordered architectures consistent with experimental benchmarks; however, under increasing solvent stress, their behaviors diverge markedly. DPPC membranes display gradual thinning, modest area per lipid …

Summer Melt: The Transition Of Rural Students To Post-Secondary Schools, Niquan Alston

Dissertations

Rural high-achieving students face unique challenges as they prepare to transition to college. While many graduate with aspirations for higher education, a significant number fail to transition to college in the fall due to barriers that arise between high school graduation and college enrollment. Rural schools, particularly those serving low-income populations, frequently lack the resources, counseling, and exposure opportunities that help students navigate the transition from high school to postsecondary education. These circumstances leave students to manage financial barriers, incomplete paperwork, limited support, and the pressures of balancing family and community responsibilities. Their lived experiences shape the way they respond …

The Coping Of Special Education Directors In The Western United States, Emily Mrazek Jones

Dissertations

The special education director in a school district has a wide-reaching role. Directors rely on extensive knowledge of educational law, instruction, child development, employee supervision, school finance, and more to positively impact the education of students with disabilities. Due to the extensive nature of the role, the practice of special education administration has been found to be stressful, and many practitioners experience burnout. Thus far, research has explored the nature of the role, the reasons for special education director stress, and directors’ preferences on surveys of positive coping strategies, but has not stepped back to ask the directors how they …

Culturally Responsive Functional Communication Training For Asian Families: A Single-Subject Design Study, Guofeng Shen

Dissertations

Children with disabilities, such as autism spectrum disorder (ASD) and intellectual disability (ID), frequently experience challenges related to social communication and are at increased risk of exhibiting challenging behaviors (CBs), particularly when they lack effective means to express their needs and desires. Functional communication training (FCT) is an evidence-based intervention shown to reduce CBs by teaching functional communication skills. However, limited research has explored the use of culturally responsive adaptations of FCT (CRFCT), particularly in the context of training parents from culturally, linguistically, and economically diverse backgrounds. This study addressed this gap by examining the effects of culturally responsive FCT …

Exploring The Use Of Culturally And Linguistically Responsive Practices Within The Multi-Tiered System Of Support (Mtss) Framework When Supporting Students With Disabilities At A Dual Language Immersion School, Sylvia Simmons

Dissertations

The integration of culturally and linguistically responsive practices (CLRP) within the Multi-Tiered System of Support (MTSS) framework has been recognized as a promising method for improving learning opportunities for diverse students. However, little to no research has been conducted on the intersection of CLRP within the MTSS framework to support students with disabilities in dual language immersion schools (DLI). This lack of research has posed challenges for educators seeking effective strategies to support diverse learners with disabilities in such settings.

Student Engagement In High School Mathematics Blended Learning Classrooms, Therese A. Rinehart

Dissertations

Engagement is a student’s interest, participation, and motivation in the learning process and is a cornerstone of success in the classroom. The COVID-19 Pandemic overturned the traditional classroom, making the task of fostering engagement nearly impossible. Although pandemic-related research has largely focused on mental health and academic achievement, less attention has been given to instructional models promoting engagement in remote learning environments. Self-directed learning (SDL) is one model offering students digital autonomy and access to teachers and peers. This study examined the longitudinal data of student perceptions of their engagement through the COVID-19 Pandemic at an alternative high school and …

Teacher Leadership And Specially Designed Instruction: A Phenomenological Study Of The Lived Experiences Of Teacher Leaders And Special Education Teachers In Elementary Settings, Tangie M. Rahming

Dissertations

This qualitative phenomenological study examined the lived experiences of teacher leaders and special education teachers as they implemented Specially Designed Instruction (SDI) in elementary school settings. Despite SDI being a federally mandated component of the Individuals with Disabilities Education Act (IDEA), research consistently shows wide variation in how teachers interpret, deliver, and sustain SDI in real classrooms. Limited professional development, inconsistent coaching structures, and varying understandings of SDI across schools contribute to persistent gaps in implementation fidelity. To address these challenges, this study explored how teacher leaders support SDI implementation and how special education teachers make meaning of their instructional …

Culturally Relevant Pedagogy In Teaching And Learning In High School Social Studies Curricula In Georgia: A Case Study, Sharon Ann Mcmeans-Lukiri

Dissertations

Despite increasing diversity within Georgia’s high school student population, it remains unclear to what extent social studies teachers incorporate Culturally Relevant Pedagogy (CRP) in the planning and implementation of their instruction. Recent research indicates that many educators continue to struggle with developing effective instructional practices that meet the learning needs of students from vulnerable communities (Liasidou & Symeou, 2018). Students from these communities often experience lower academic achievement (Ladson-Billings, 2009), and when the curriculum fails to reflect or respond to their cultural backgrounds, they are more likely to disengage from school (Ladson-Billings, 2009). This gap between students’ cultural needs and …

This study has been designed as a case study to examine teachers’ perceptions of document-based strategies when combined with primary sources as pedagogical tools. The participants were ninth grade civics teachers. Semi-structured interviews, focused observations, and artifact collection were the sources of collected data. As the researcher, my constructivism guided this study through the lens of Albert Bandura’s social cognitive theory (SCT). Therefore, the participants’ perception will be interpreted through SCT concepts such as personal influences, behavioral influences, and environmental influences. Findings show a handful of disciplinary literacy strategies that occurred most often across all participants. Teachers valued an emphasis …

Factors Affecting Diet Selection In Sheep Fed Endophyte-Infected Toxic Fescue, Jordan Thomas

Animal Science Undergraduate Honors Theses

Tall fescue infected with endophyte‑producing fungi can induce fescue toxicosis in grazing ruminants, reducing performance and altering forage intake. Isoflavones—such as biochanin A, a major compound in red clover (Trifolium pratense)—have been proposed to mitigate these effects through improved palatability and vascular relaxation. This study examined whether inclusion of ground red clover (GRC)—either directly or combined with hydroxypropyl methylcellulose (HPMC) and polyethylene glycol (PEG)—affected voluntary diet selection in lambs offered toxic fescue.

Thirty‑two lambs were housed individually and assigned randomly to one of four diets: (1) toxic fescue silage (CONT), (2) silage + 5% GRC (RC5), (3) silage + 10% …

2025 December - Tennessee Monthly Climate Report, Tennessee Climate Office, East Tennessee State University

Tennessee Climate Office Monthly Reports

Hi All,

December was defined by quite a bit of temperature variability (though the temperature swings resulted in near-normal monthly averages) and an overall dry pattern.

The month started out cooler than normal, with a slight moderation in the second week of the month, before a strong cold front sent temperatures tumbling into the teens or single-digits and wind chills into the single digits or below zero on December 14 and 15 - with many locations stuck in the 20’s or even teens for high temperatures. Following this cold weather, temperatures quickly rebounded into the normal and then well above …

Detection Of Phase-Binning And Interpolation Artifacts In 4-Dimensional Computed Tomography Imaging Using Deep Learning And Rule-Based Approaches, Jorge Cisneros, Nathan H. Feldt, Yevgeniy Vinogradskiy, Richard Castillo, Edward Castillo

Department of Radiation Oncology Faculty Papers

BACKGROUND: Four-dimensional computed tomography (4DCT) imaging is a crucial component to lung cancer radiotherapy planning and enables CT-ventilation-based functional avoidance planning to mitigate radiation toxicity. However, 4DCT scans are frequently impaired by acquisition artifacts that corrupt downstream analyses that depend on lung segmentation and deformable image registration, such as CT-ventilation and dose accumulation.

PURPOSE: This study develops 3D deep learning models to identify phase-binning artifacts at the voxel level and a heuristic, rule-based method to identify interpolation slices within 4DCT images.

METHODS: We introduce a generator that systematically inserts synthetic phase-binning and interpolation artifacts into any artifact-free breathing phase obtained …

(Wp 2025-06) Ramsey And Keynes...And Sraffa And Wittgenstein: Change In Interwar Cambridge Economics And Policy, John B. Davis

Economics Working Papers

The Ramsey-Keynes exchange regarding the nature of probability is investigated in connection with the development of interwar Cambridge economics and Ramsey and Sraffa’s influences on Keynes and Wittgenstein. First discussed are Ramsey’s criticisms of Keynes and Wittgenstein; then Sraffa’s criticisms of Marshall and Wittgenstein. Ramsey was influenced by Peirce and pragmatism and Sraffa by Gramsci and the theory of cultural hegemony. Ramsey died in 1930 but Sraffa continued to interact with both Keynes and Wittgenstein. After his critique of Marshall he participated in the ‘Cambridge circus’ and turned to recovering the Classical economics of Ricardo. Keynes’s General Theory statement of …
