Edna Surveillance And Population Genomics Of The Invasive Loaches Introduced To The United States, Tobin J. Davidson
Theses and Dissertations
Invasive species represent a growing threat to the ecosystems and economies of the United States. The southeastern United States is an aquatic biodiversity hotspot, and the decline of multiple native species already facing extinction is attributed to a rapidly growing number of nonindigenous freshwater fishes. Next-generation sequencing was used to analyze the population genomics of several populations of Pond Loach (Misgurnus anguillicaudatus) introduced to the United States. Three evolutionarily significant units of Misgurnus loaches were found, suggesting the invasion of multiple different species in the United States. Additionally, noninvasive environmental DNA (eDNA) protocol designed for early detection of invasive freshwater …
The Evaluation Of Traditional And Latency Based Functional Analyses On The Identification Of The Function Of Inappropriate Mealtime Behavior, Mallie N. Donald
The Evaluation Of Traditional And Latency Based Functional Analyses On The Identification Of The Function Of Inappropriate Mealtime Behavior, Mallie N. Donald
Theses and Dissertations
Research indicates that up to 80% of children with developmental disabilities have feeding problems. Feeding problems typically coexist with the presence of inappropriate mealtime behavior which includes behaviors such as aggression, throwing food or utensils, or turning head away from the presented bite. As a result, functional analysis procedures are commonly used to determine the function of inappropriate mealtime behavior to later inform effective function-based interventions. Traditional functional analysis procedures utilize the measurement of the rate of inappropriate mealtime behavior. Several limitations exist within traditional procedures for the assessment of inappropriate mealtime behavior which include demands across all test and …

Topnet R1: A Multi-Stage Ai Framework For Topic Discovery In Scientific Abstracts, Md Elias Hossain
Theses and Dissertations
Scientific abstracts are rich sources of knowledge, yet extracting meaningful topics remains challenging due to limitations in existing topic modeling techniques. Traditional methods often struggle with interpretability, scalability, and contextual understanding. To overcome these issues, we introduce TopNet R1, a multi-stage ensemble framework that integrates traditional topic models with contextual embeddings from Bidirectional Encoder Representations from Transformers (BERT) and Generative Pre-trained Transformer 4 (GPT-4) large language models (LLMs). Top- Net R1 operates in three phases: (1) topic generation using Latent Dirichlet Allocation (LDA), Non-Negative Matrix Factorization (NMF), Latent Semantic Analysis (LSA), and Hierarchical Dirichlet Process (HDP); (2) LLM-assisted pattern recognition …
Strategic Use Of Exogenous Feed Enzymes And Sodium Bisulfate To Optimize Broiler Production, Spencer Thomas Karn
Strategic Use Of Exogenous Feed Enzymes And Sodium Bisulfate To Optimize Broiler Production, Spencer Thomas Karn
Theses and Dissertations
Poultry producers must continually evaluate nutritional strategies to enhance broiler performance and sustainability. Chapter II assessed sodium bisulfate (SB) applied to litter, feed, and water across a 42-day grow-out. Applying SB to litter reduced pH, while 0.3% and 0.4% dietary SB improved feed conversion ratio (FCR). Water acidification with SB during the final week did not impair performance, supporting its use as a preharvest intervention. Chapter III evaluated phytase at 500, 1500, and 2000 FTU/kg, with or without protease, in reduced amino acid diets over 56 days. Birds fed a nutrient-adequate diet with 1500 FTU/kg phytase outperformed all reduced-amino acid …

Understanding Pollinator-Forb Interactions And Evaluating Trapping Methods For Pollinator Monitoring In Lawns Of The Southeastern United States, Sara Rose Kirby
Theses and Dissertations
Urban turfgrass landscapes are widespread across the southeastern United States but offer limited ecological value under conventional management. This thesis evaluates the pollinator support potential of ten forb species commonly found in low-maintenance lawns and assesses the effectiveness of two insect sampling methods, sweep netting and pan trapping. Over two years of field surveys, native forbs such as Symphyotrichum divaricatum and Claytonia virginica supported significantly greater insect abundance and diversity than introduced species. Network and modularity analyses revealed that native plants facilitated more specialized pollinator interactions, including those involving oligolectic bee species. In a complementary study, pan traps effectively sampled …

My Grandparents Raised Me: The Role Of Formative Individual And Family Experiences In Predicting Emerging Adult Substance Use, Attachment, And Mental Health Outcomes, Acacia Lopez
Theses and Dissertations
Individuals raised in a grandfamily, or family structure in which a grandparent raises their grandchildren, experience higher rates of adverse childhood experiences (ACEs), insecure attachment, and negative mental health outcomes during childhood. Literature on outcomes of these individuals across the lifespan is extremely limited, however, and it is unclear how formative individual and family experiences of being raised by grandparents carry into emerging adulthood (e.g., 18 to 25-years-old). Emerging adulthood is a developmental stage marked by significant instability and unpredictability that is linked with increased vulnerability to mental health concerns and substance use. It has been identified as an important …
Finite Element Modeling Of Plasma Membrane Injury From Mechanical Stress: A Combined Finite Element And Machine Learning Approach, Eric Flynn Mabowitz
Finite Element Modeling Of Plasma Membrane Injury From Mechanical Stress: A Combined Finite Element And Machine Learning Approach, Eric Flynn Mabowitz
Theses and Dissertations
Low back pain is a leading cause of disability across a wide range of occupations and environments. Exposure to whole-body vibration (WBV) has been linked to an increased prevalence of low back pain, as well as certain neurophysiological complications. While current understanding of WBV effects is largely based on tissue- and whole-body-level studies, a significant gap remains in knowledge regarding how vibrational forces propagate through individual cells. This knowledge gap limits a comprehensive understanding of how these forces affect the human body at the microscopic level. To address this, the present study employs both two-dimensional (2D) and three-dimensional (3D) finite …

Synthetic Mrna Induced Tf1.17-Specific Antibody Response Against Tritrichomonas Foetus For Preputial Delivery In Bulls, Kenzie Mcatee
Theses and Dissertations
Bovine trichomoniasis, caused by Tritrichomonas foetus, remains a persistent reproductive disease in cattle due to asymptomatic carriage in bulls and lack of effective treatments. This thesis evaluated the use of synthetic mRNA to drive expression of TF1.17- specific antibodies, targeting a conserved surface adhesin essential for parasite colonization. Membrane-anchored and secreted IgG1 constructs were transfected into bovine kidney cells, resulting in time-dependent antibody expression verified via NanoLuc luminescence. In vivo, aerosolized mRNA administration to bull calves led to localized antibody expression in preputial secretions. Although immunofluorescence assays detected fluorescence signal, high background limited interpretation of specific binding to T. foetus. …

Development of alternative treatments for wood product protection is an ongoing focus throughout the wood products industries. All manufacturers hope to increase the use life of their products, while ensuring that their products do not have a harmful impact on their surrounding environment. One way of approaching this is to source potential components from other agricultural sources. Guayule resin is produced as a by-product of rubber extraction from the guayule plant (Parthenium argentatum). The resin has been reported to have insecticidal and microbial properties, but there are numerous problems with utilization, including how to extract it and apply it due …
Sweetpotato Insect Pests: Virus Vector Management And Rearing, Rachel Emily Morrison
Sweetpotato Insect Pests: Virus Vector Management And Rearing, Rachel Emily Morrison
Theses and Dissertations
Sweetpotatoes (Ipomoea batatas) are vegetatively propagated through slips, making them prone to viral buildup. Aphids are insect pests known for transmitting viruses to crops, which reduces yield. This study examined different options for aphid management to reduce the spread of potyviruses: crop borders, crop oils, and insecticides. However, the results of this research showed that treatments were not successful at reducing the spread of the four potyviruses tested. An additional objective was to establish a colony of banded cucumber beetles (Diabrotica balteata) in the laboratory. These beetles are a leaf-feeding and root-feeding pest of sweet potatoes. Two colonies of banded …

Augmenting Healthcare Communication: Context-Aware Ai Frameworks For Clinical Decision Support And Automated Summarization, Subash Neupane
Theses and Dissertations
Healthcare communication is plagued by fragmented medical knowledge, patient misunderstanding of care plans, and clinician burnout from documentation burdens. These inefficiencies cost the U.S. healthcare system over $300 billion annually due to preventable nonadherence and administrative waste [47, 19]. While Artificial Intelligence (AI) technology like Large Language Models (LLMs) offer potential solutions, existing systems fail to deliver personalized, context-aware guidance or automate documentation without sacrificing accuracy. This dissertation addresses these gaps through three novel context-aware AI frameworks such as MedInsight, ClinicSum, and ClinicDuo. MedInsight leverages a multi-source context augmentation approach to synthesize patient centric medical responses by integrating Electronic Health …
Decision-Making And Execution Skill Estimation In Continuous Action Space Domains, Delma I. Nieves-Rivera
Decision-Making And Execution Skill Estimation In Continuous Action Space Domains, Delma I. Nieves-Rivera
Theses and Dissertations
In many real-world domains with continuous action spaces, an agent’s performance is driven by two key factors: its decision-making skill, or ability to select high-quality actions, and its execution skill, or precision in carrying out these actions. However, accurately evaluating these skills, particularly when direct information about the agent’s intentions is unavailable, remains a challenging problem. This research addresses this need by developing a theoretical framework and proposing novel estimation methods to assess both decision-making and execution skills based solely on observable data: executed actions and their associated rewards. The work consists of six core studies focused on developing and …
