Testing The Effects Of Mechanical Stimulation On Mesenchymal Stem Cell Cultures, Ella Collis

2026 Research Poster Competition

Mesenchymal stem cells (MSCs) are a promising treatment option for a variety of diseases due to their ability to migrate to far-off sites, modulate inflammatory immune responses, secrete factors that aid in tissue healing, and their capacity to become several cell types. These cells can be found and isolated from various body tissues including bone marrow and adipose tissue, even so the number of cells obtained from these tissues is minimal compared to the amounts needed for their transplantation in cell therapy treatments. Therefore, their culture in plastic dishes is required to increase the number of cells and obtain the …

Flair- Flow-Level Anomaly Intrustion Recognition, Joseph Dumond

2026 Research Poster Competition

Industrial control systems (ICS) and industrial Internet of Things (IIoT) networks support critical infrastructure such as power generation, water treatment, and manufacturing. As these systems become more connected, they are increasingly exposed to cyber threats. However, many existing intrusion detection approaches rely on detailed packet inspection or supervised machine learning techniques that require labeled attack data and extensive tuning, making them difficult to deploy in real industrial environments.ICS networks typically generate highly regular and predictable communication patterns due to periodic control logic and deterministic device behavior. Because of this structure, abnormal or malicious activity often appears as a disruption to …

When Relevant Isn’T Readable: Evaluating Cognitive Accessibility In Search, Kaija Frierson

2026 Research Poster Competition

According to the World Health Organization, more than one billion people worldwide experience some form of disability. Many of them may affect cognitive processing and reading comprehension rather than vision or mobility, which creates barriers when accessing written information online. Web search is a critical modern literacy skill used for learning, decision-making, and everyday problem solving, yet most search systems are designed with the assumption that all users can process complex written language equally. As a result, people with dyslexia, other cognitive disabilities, low literacy levels, or who are English language learners may struggle to access relevant information even when …

Monitoring Streambank Morphology Using Iphone Lidar Technology, Lily C. Stitt

2026 Research Poster Competition

Monitoring stream morphology is crucial for maintaining the health and safety of fluvial environments, particularly as these naturally dynamic systems are shifted out of equilibrium due to climate and land-use change. Quantifying these changes in stream geometry is useful for infrastructure design, water quality assessment, water resource management, and stream restoration, among other applications. Traditional stream surveying methods contain limitations that inhibit affordable and accessible stream surveying needed for evaluating fluvial systems with high accuracy and large data samples. In recent years, several advancements have been made in the use of Light Detection and Ranging (LiDAR) technology as an alternative …

P4 Driven Data Plane Analytics For Industrial Control Network Security, Haden Fowler

2026 Research Poster Competition

Industrial control systems manage critical infrastructure such as power grids, water treatment plants, and manufacturing facilities. These systems rely on specialized network protocols to send measurements and commands between sensors, controllers, and operator workstations. Protecting these networks from cyberattacks is essential because a successful intrusion could disrupt services that millions of people depend on daily. Most current security monitoring approaches analyze copies of network traffic after it has already passed through the system. This delay means that malicious commands may reach their targets before any alarm is raised. More importantly, when alerts do occur, operators often lack the evidence needed …

Analysis Of Potential Alkali Reactivity Of Aggregates In Arkansas, Brigita Dowling

2026 Research Poster Competition

Alkali Silica Reaction (ASR) is a deleterious chemical reaction in concrete that leads to the deterioration of concrete structures. This reaction occurs between minerals present in aggregates and alkalis in the cement, and produces a gel-like substance called alkali silicate gel. Gradually, these gels absorb water from the environment and expand, leading to internal stresses in the concrete. This damage results in expansion, cracking, and deformation, reducing the strength and durability of the concrete significantly. While this damage appears minor initially, eventually they can lead to the need for costly repairs or replacement of the concrete. ASR has been observed …

Development Of A Scalable 32x32 Capacitive Sensing Array Using Fpga Controlled Multi-Bus I2c Communication, Jonathan Digby

2026 Research Poster Competition

High-resolution capacitive sensor arrays are widely used in applications such as robotics, wearable devices, and biomedical devices where accurate detection of touch, proximity, and motion is crucial. As these systems are scaled up to achieve higher resolutions, challenges pertaining to communication reliability, data synchronization, and system latency become more important. Capacitive sensor arrays detect changes in capacitance caused by disturbances in nearby electric fields. While these arrays are effective at small scales, large arrays often suffer from signal degradation and latency when all sensors rely on a single controller and communication bus. This research addresses these challenges by developing a …

Solidfit: A Decentralized Mobile Health-Tracking App Using Personal Online Data Stores (Pods), Evan Meyers

Personal fitness data is increasingly collected through mobile applications, yet most current systems store this information in centralized platforms that limit user control, long-term ownership, and data portability. This project addresses the question of whether a decentralized data model can be used to support everyday fitness tracking while preserving user autonomy and privacy. As individuals become more aware of how their health data is collected and shared, there is a growing need for systems that allow users to retain ownership of their personal information without sacrificing usability or functionality.This research presents SolidFit, an Android-based fitness tracking application designed around the …

Developing A Cpp-Conjugated Cas9 Library For Efficient Non-Viral Delivery To The Dmd Gene, Amie Donathan

2026 Research Poster Competition

Duchenne muscular dystrophy, or DMD, is a genetic neuromuscular disorder caused by the mutation of the DMD gene, resulting in alterations in the functionality or production of dystrophin, a protein essential to maintain muscle fiber integrity and strength. This mutation leads to progressive muscle degeneration, causing motor loss, cardiopulmonary failure, and ultimately, premature death. Gene therapies using CRISPR aim to replace the mutated gene to provide long-term correction. Although this has promise, CRISPR-based therapies use a viral vector to deliver, which presents notable challenges, such as immune problems and liver toxicity. A non-viral delivery method is a viable approach, but …

The Federal Rules Of Evi-Dance: Exploring And Reimagining Evidence Law Through Music, And Proposing Amendments To Rule 604, Brian C. Potts

Faculty Articles

Every trial has a rhythm and a flow. Every trial is a performance. This article extends the literature on law and music further into the field of evidence. I offer a new exploration and reimagining of the Federal Rules of Evidence through leitmotivs. I contend that leitmotivs—musical calling cards—reify principles of evidence law. As I spin these leitmotivs, I propose two amendments to Rule 604 regarding the oath for courtroom interpreters. I propound a new critique explaining how and why courts are wrong when they often claim “Daubert did not work a ‘seachange’ over federal evidence law.” I tender two …

Evaluating Willow Establishment With Biochar For Remediation Of Mine Waste Soils: Amendment Ph Determines Plant Biomass And Metal Mobility, Madeline R. Webb

Dissertations, Master's Theses and Master's Reports

Heavy metal contaminated mine tailings (“stamp sands”) from historic copper mining inhibit plant establishment and contribute to ongoing metal contamination. Biochar amendments may enhance plant growth and reduce metal mobility in highly permeable mine waste soils, but the efficacies of different application methods or biochar sources and composition are uncertain. We evaluated different biochar sources (neutral or alkaline pH) and application methods (either mixed or layered) for planted willow growth, moisture retention, and metal mobility. A 10-week growth chamber experiment assessed plant performance, heavy metal content and heavy metal mobility in soil leachates and plant tissues. Biochar pH was the …

Origin Of The World-Class Eagle, Eagle East, And Tamarack Ni-Cu-Pge Deposits And Comparative Analysis With Other Midcontinent Rift- And Siberian Trap-Related Intrusions, Robert M. Nowak

Dissertations, Master's Theses and Master's Reports

The 1.1 Ga Mesoproterozoic Midcontinent rift hosts the Eagle, Eagle East, and Tamarack Ni-Cu-PGE deposits and Embayment Prospect. These deposits are hosted by ultramafic igneous rocks and have some of the highest Ni-Cu grades on Earth. We use new bulk-rock data and published datasets (bulk-rock, mineral chemistry, and isotopic analyses) to examine major, minor, and trace element trends of both Midcontinent rift-related alkaline and tholeiitic intrusions. In addition, we compare the geochemical data to local kimberlite-hosted lower-crustal xenoliths and local igneous (Archean) and sedimentary (Paleoproterozoic) country rocks. We found the peridotite magma compositions dominantly consist of primitive mantle compositions with …

Potential Of Stamp Sands As Cemented Tailings, Samuel Sukaria

Dissertations, Master's Theses and Master's Reports

Worldwide mine tailings ponds and reservoirs occupy some 534 billion m³ of space with the volume expected to increase as economic demand for minerals increases over the next decades. These reservoirs produce adverse effects on local communities and ecosystems through structural failure resulting in mass flooding events, drainage of pollutants into water supply and emissions of airborne particulate matter. Methods developed to find use for tailings include extraction of residual minerals and aggregates in construction materials. The latter method has already been used in mining operations to stabilize mining reservoirs and stopes, and as placement for temporary road work …

Florida Local Public Administrator Perspectives On Decentralized Wastewater Treatment, Jude Hagan

Honors Undergraduate Theses

Decentralized wastewater treatment (DWT) systems, such as onsite greywater recycling and septic systems, have been demonstrated to be a potentially more sustainable, cost-effective, and disaster-resilient alternative to traditional centralized systems by treating wastewater at or near the source. However, many barriers exist that have prevented the widespread implementation of DWT, such as public opposition, lack of resources, government regulations, public health concerns, and capital costs. In this study, local emergency managers, urban planners, and utility/wastewater managers in Florida were surveyed to determine their perceptions and levels of knowledge on DWT. The results of this study were inconclusive due to a …

Regulation Of The Low-Density Lipoprotein Receptor In A Colon Cancer Cell Line By The Prostasin Serine Protease, Juan Pablo Ruiz

Honors Undergraduate Theses

In the effort to combat hypercholesterolemia and cardiovascular disease, research has turned to studying the effects of serine proteases on the low-density lipoprotein receptor (LDLR), which plays a key role in the diseased states with high LDL levels. Matriptase has been shown to proteolytically shed the extracellular domain (ECD) of the LDLR in the co-translational setting. Prostasin (PRSS8) and matriptase (ST14) are part of a proteolytic activation cascade and it is hypothesized that the coactivation of prostasin and matriptase or a pharmacological perturbation of the steady state could result in LDLR ECD shedding in cells co-expressing the receptor and the …

Comparative Spatial Biology: A Cross-Species Analysis Of Canine Oral Cancers As Models For Human Disease, Ram Pradhyumnan

Honors Undergraduate Theses

Oral squamous cell carcinoma (OSCC), one of the most common malignancies of the oral cavity, remains a clinically challenging disease due to its aggressive behavior, late-stage diagnosis, and limited improvements in therapeutic outcomes over recent decades. A significant barrier to progress in OSCC research and treatment is the lack of suitable preclinical models that recapitulate the complexity and natural progression of the disease. Most current models—including cell lines, xenografts, and genetically engineered mice—fail to capture key features such as the spatial organization of tumor epithelium, interactions with an intact immune system, and the stepwise evolution from normal mucosa to invasive …

Who Makes The Jury? Demographics And Decision-Making In The Jury Process., Ana B. Pons

Honors Undergraduate Theses

Within the American judicial system, juries have played a central role in promoting representation and fairness in the courtroom. However, limited information exists on whether prosecutorial decisions during jury selection, jury composition, or jury behavior differ based on the sex, race/ethnicity, type of case, political ideology, or geographic location of potential jurors. Following PRISMA guidelines, this scoping review synthesizes 48 peer-reviewed articles published between the 1940s and 2026 to examine whether prosecutorial decision-making and jury outcomes vary based on the sex, race/ethnicity, type of case, political ideology, or geographic location of potential jurors. Findings indicated that men are disproportionately selected …

Invasion Of Microplastics Into The Reproductive Tissues Of Feral And Domestic Felines, Emma K. Quade

Honors Undergraduate Theses

Although plastics have many useful properties in modern society, once these materials are introduced into the environment, they can cause extensive damage. Following degradation into microplastics (MP), plastic particles less than 5 mm in size, these contaminants can make their way into a variety of different environments and organisms. There are many studies that have investigated the prevalence of MP in marine environments, but fewer studies have looked into terrestrial systems, and even less that have focused on contamination in companion animals. This study sought to investigate the invasion of MP into the reproductive tissues of felines, Felis catus, …

The Relationship Between Physical Behaviors, Perceived Stress, Oral Hygiene Awareness, And Periodontal Disease Among College Students, Gustavo Quilula

Honors Undergraduate Theses

Periodontal disease (PD) is a preventable inflammatory disease that targets the supporting tissues that surround teeth. PD is extensively studied among older adults, but there is limited evidence of the prevalence of PD and potential modifiable risk factors among young adults. The purpose of this study is to assess the prevalence and severity of PD among U.S. college students and (2) examine the association between objectively measured physical activity (PA), oral hygiene awareness, perceived stress, and PD symptoms. College students from a large metropolitan university were enrolled in this cross-sectional study. Oral hygiene knowledge, PD symptoms, and perceived stress were …

Interaction Of The Dap-10 Fluorescent Light-Up Aptamer With An Environment-Sensitive Dye, Crystal Violet, Marina Tsukanova

Honors Undergraduate Theses

Crystal violet (CV) is an environment-sensitive dye whose fluorescence is strongly influenced by microenvironment polarity and viscosity, increasing markedly when rotational and vibrational motions are restricted. While the fluorescence enhancement of CV by fluorescent light-up aptamers (FLAPs) has been noted in literature, the specific binding interactions between CV and aptamers in the DAP-10 family have remained under-investigated.  The objective of this work is to elucidate the binding site interactions between CV and the DAP-10-42 FLAP. It is hypothesized that positions 34 and 35 of the aptamer’s sequence reside in a proposed quadruplex-duplex junction that form the dye-binding pocket of DAP-10 …

How Does The Frequency Of Visits Impact The Quality Of Life For Nursing Home Residents?, Sophie M. Carlton

Honors Undergraduate Theses

This integrative literature review examines the relationship between quantity of visitation and quality of life (QOL) of nursing home residents. The purpose of this review is to examine existing research to determine whether an optimal “dosage” of visitation exists that meaningfully enhances QOL for this vulnerable population. Establishing an evidence based- guideline may help reduce uncertainty for families and promote more consistent improvements in resident well-being. Nursing home residents are the focus of this work because their limited ability to leave the facility makes visitation one of their primary sources of non-occupational social interaction. The COVID19 pandemic further heightened the …
