Two 75-minute sessions were conducted over a two-month period, with a total of 27 students participating. The first session included a focused electrocardiography didactic emphasizing ST-elevation myocardial infarction (STEMI) recognition, …

Mycobacterium Chimaera In A Young Patient Without Underlying Cardiac Surgery History, Kate A. Szczesniak, Rakesh Shah, Malitha Hettiarachchi

Conference Presentation Abstracts

Introduction/Objective Mycobacterium chimaera (M. chimaera), within the Mycobacterium Avium Complex (MAC), is a slow-growing nontuberculous mycobacterium (NTM) species that is most often characterized by nonspecific symptoms of night sweats, fever, and fatigue. Due to the nonspecific symptoms of M. chimaera and the rarity of this infection, delayed or misdiagnosis occurs in these patients. Risk factors of contaminated heater-cooler units used in cardiac surgery have been reported; however, cases without this exposure, such as this case, have been cited less commonly. This case of M. chimaera will present a young patient initially presenting with dyspnea who was found to have a …

Evaluating Fungal Endophytes Inoculation As A Mechanism For Salt Tolerance In Juncus Roemarianus, Rani Badve

Honors Theses

Salinity stress is increasing in coastal and estuarine ecosystems due to increasing temperatures and the reduction of freshwater inputs via precipitation pattern changes. Elevated salinity can negatively affect plant survival, threatening the stability of coastal wetlands and the ecosystem services they provide. Juncus roemerianus is a common and dominant marsh plant in the Northern Gulf Coast that lives in varying salinities. Growing evidence suggests that root-associated fungal endophytes may contribute to enhanced stress tolerance; however, the response of fungal communities to salinity remains poorly understood.

This study evaluated how salinity influences the abundance and diversity of culturable root-associated fungal communities …

Targeting The Dorsolateral Prefrontal Cortex With Transcranial Direct Current Stimulation To Improve Depression And Anxiety In Parkinson's Disease, Brock Renicks

Honors Theses

The aim of this study is to observe the outcomes of transcranial direct current stimulation (tDCS) as a treatment for Parkinson’s Disease (PD). This study will primarily look at changes in depression and anxiety, as these symptoms are often comorbid with Parkinson’s Disease. Transcranial direct current stimulation is a non-invasive, very low-intensity form of electrical stimulation of the brain. It is being increasingly used as a form of treatment for Parkinson’s Disease and depression and anxiety, however the literature is ambiguous, showing mixed results throughout various studies, with no standardization of tDCS administration. To determine the effect of tDCS on …

Navigating The Nicu Without Words: A Case Study Of A Spanish-Speaking Mother’S Healthcare Experience, Emma Norris

Honors Theses

Background: Few studies examine language barriers in the neonatal intensive care unit (NICU). Miscommunication and lack of understanding between the healthcare team and a NICU infant’s parents may easily occur when the relationship is inhibited by a language barrier. Previous studies show that a lack of parent-provider communication creates additional anxiety for parents. The purpose of this study is to explore and describe the experiences and barriers in communication between an English-speaking nurse, an English-Spanish bilingual nurse, and a Spanish-speaking mother of a NICU infant.

Methods: This project was a case study using an exploratory mixed methods qualitative design. Qualitative …

Community Perceptions Of A Hospital-Based Doula Program In Mobile, Alabama, Sarah Laney

Honors Theses

Background: The maternal mortality ratio in the United States is much higher than the mortality rate for women who live in other countries with similar Human Development Index scores. Black women are more likely to die than their white counterparts. Most of these deaths are preventable. Patients feel like they are being ignored, or that they are not being seen. Doula care is a possible solution to these problems.

Purpose: The purpose of this study was to assess patient understanding and perception of doulas as well as comparing desire for doulas to demographics and past experiences to search for relationships. …

Improving Fairness On Semantic Segmentation Using Large Language Models, Samuel E. Burggraf

Electrical & Computer Engineering Projects for D. Eng. Degree

As machine learning systems are increasingly integrated into critical decision-making processes, ensuring fairness in their design and implementation has become a significant concern. While fairness research has primarily focused on specific protected attributes, less attention has been given to spatial fairness, which can affect individuals at specific locations. If fairness is not addressed, models may systematically underperform in certain regions or across populations which can lead to unequal access to accurate predictions and potentially biased decision-making. Fairness considerations should extend across all machine learning applications to align with the National Institute of Standards and Technology (NIST) guidelines of fair and …

How Presentation Shapes Multisensory Category Learning, Hooman Main Amiri

Master's Theses and Capstones

Category learning allows people to group complex sensory input into categories, helping them generalize knowledge from familiar exemplars to novel stimuli. In everyday life, categories are often learned from more than one sense, yet most prior work on category learning has focused on learning in a single sensory modality. Here, we asked whether the way category information is presented across modalities, simultaneously or separately, shapes multisensory category learning in adults. In Experiment 1, participants learned the categories with either simultaneous or separate presentation of auditory and visual information and then completed a test phase to assess not only whether they …

Gli2-Mediated Regulation Of Immunoglobulin Class Switching And Heavy Chain Locus Activity, Casey Paige Baumann

Master's Theses and Capstones

Class switch recombination (CSR) enables B cells to generate antibodies with diverse effector functions through recombination at the immunoglobulin heavy chain (IGH) locus. This process requires coordinated transcriptional activation and DNA repair, yet its regulation remains incompletely defined. The transcription factor GLI2, a mediator of Hedgehog signaling, has been implicated in transcriptional control, but its role in CSR and IGH regulation is not well understood. To investigate the contribution of GLI2 to CSR, splenocytes from WT and hematopoietic-specific Gli2-deficient (H-Gli2-/-) mice were stimulated ex-vivo to induce switching to IgG1. Analysis of germline transcription, DNA repair enzyme expression, and post-switch transcripts …

Conserved Spatial Proximity And Immune-Linked Evolution Of Lncrnas From Protein-Coding Genes In Vertebrates, Sahar Jamialahmadi

Master's Theses and Capstones

Long non-coding RNAs (lncRNAs) are widespread components of vertebrate genomes, yet theevolutionary principles governing their genomic positioning, origin, and functional associations remain incompletely understood. Here, we performed a comparative genomic analysis across 96 vertebrate species to investigate the spatial relationship between lncRNAs and protein-coding genes, their evolutionary trajectories within gene families, and their functional and genomic contexts.

We show that lncRNAs are consistently positioned in close proximity to protein-codinggenes across vertebrates, with distance distributions significantly deviating from random genomic placement in all species examined. Despite this non-random organization, genome-wide lncRNA–mRNA distance distributions were highly conserved across species. Ancestral state reconstruction …

Economic Feasibility Of Aquaponics In The Cold-Climate Eastern United States: A Multi-Facility Monte Carlo Analysis, Ryan Nickerson

Master's Theses and Capstones

Most commercial aquaponics facilities fail to achieve profitability, and this challenge is exacerbated in cold climates, where heating, supplemental lighting, and insulated infrastructure inflate operating costs. Existing economic studies are dominated by warm-climate, single-facility cases, offering limited insight into whether cold-climate operators in the eastern United States can achieve profitability through design choices around scale, species selection, and labor optimization. This thesis evaluated the market feasibility of three research facilities (the University of New Hampshire, the University of Maryland, and Ohio State University) and one commercial facility in New Hampshire. The model used a discounted cash flow framework with parameters …

A Data-Driven Assessment Of Coastal Roadway Vulnerability Using Observed Storm Damage Locations, Jack Kearing

Master's Theses and Capstones

Coastal roadways are increasingly vulnerable to storm impacts and sea level rise. One common failure mode during these events is roadway washout, defined in this study as the physical loss or structural failure of roadway segments due to erosion, overtopping, or hydraulic failure. Washout events can disrupt transportation networks, restrict emergency access, and isolate coastal communities, highlighting the need for improved predictive methods that move beyond index-based assessments toward data-driven identification of vulnerable roadways.This study develops a data-driven framework for assessing roadway washout vulnerability using observed damage data and environmental predictors. Machine learning models, including random forest and decision tree …

Vegetation Mediates Methane Ebullition Across Temporal Scales In A Temperate Peatland: A 10-Year Dataset, Apryl L. Perry

Master's Theses and Capstones

Wetlands are the largest and most variable natural source of methane (CH₄) to the atmosphere, contributing an estimated 161 Tg CH₄ yr-1 globally. Climate and anthropogenic changes can alter hydrology, geochemistry, and vegetation, generating substantial variability in CH₄ emissions across landscapes. Long-term measurements of CH₄ fluxes, inclusive of all transport pathways (ebullition, plant transport and diffusion), are rare but essential for understanding wetland contributions to the global carbon cycle. We present a decadal dataset of ebullitive CH₄ emissions from a temperate peatland, examining variation among vegetation types and relationships with environmental drivers. We found that ebullitive CH₄ fluxes were highest …

Home-Level Flood Damage Assessment With Physics-Constrained Deep Learning, James Ojoawo

Master's Theses and Capstones

Flood damage to residential buildings is commonly estimated using depth-damage functions that treat buildings as interchangeable, ignoring differences in size and layout that influence damage outcomes. In this work, we present a physics-informed neural network that incorporates building characteristics (floor area, bedrooms, bathrooms, stories and garage spaces) and reduces physically implausible predictions in which damage decreases as flood depth rises. The model predicts both the mean and uncertainty of percent damage and is tuned to balance physical consistency and predictive accuracy. Model interpretation shows that building characteristics collectively account for nearly half of predicted damage variability, highlighting the importance of …

Scaling Of Thermal Conductivity In The Eliot Formation, Ryan Todd Siegel

This study investigates heat flow through media with spatially variable thermal conductivity within the heterogeneous Eliot Formation, a metamorphic unit extending across the coastal region of northeast New England. The objective of this work is to develop an approach for scaling thermal conductivity from core-scale measurements to field-scale values representative of geothermal borefield systems.Divided bar thermal conductivity testing, petrographic analyses, geological observations, and existing literature were integrated to construct a MODFLOW model that captures the heterogeneous thermal behavior of …

Quantifying Macrophyte Ecosystem Services And Improving Environmental Nonprofit Messaging, Peyton R. Hughey

All Theses

Environmental nonprofits are essential to the management and restoration of our natural spaces. They are also tasked with engaging the public via outreach, education, and advocacy. As natural spaces are degraded, the ability of environmental nonprofits to deliver on their missions will become increasingly important. This study aimed to improve two approaches to environmental nonprofits’ missions: ecological restoration and social media communication.

Environmental nonprofits operate with limited resources, and ecological restoration can be an exhaustive task; therefore, we explore functional restoration as a tool. In this study, we focus on the use of functional, trait-based restoration to restore ecological function …
