The Importance Of Hippotherapy: Improving The Lives Of The Disabled Through Alternative Therapy, Jennifer N. Stapleton

Undergraduate Research Posters

For centuries, horses have been suggested as “healers” and “helpers,” although it wasn’t until the 1900s that horseback riding was scientifically proven as a treatment and rehabilitation method. The exploitation of hippotherapy, the implementation of the three-dimensional pelvic movement stimulated by the oscillation and gait of the horse to combat symptoms of diseases and disorders, has since become a flourishing field of study, but one that is often overlooked. Benefits of hippotherapy often include increased motor neuron function, facilitating proper anatomical alignment, and reducing spasticity. This research analyzes the diverse and dynamic nature of treatment that hippotherapy facilitates, exploring the …

Antiestrogens As Bone Protective Therapeutics For Estrogen Receptor-Positive Breast Cancer In The Presence Of Osteoporosis, Faith E. Parker, Emily K. Zboril, David C. Boyd, Rachel Myrick, J. Chuck Harrell

Undergraduate Research Posters

Breast cancer (BC) is one of the most significant causes of mortality among women and the second leading cause of cancer death in women. The estrogen receptor (ER) is a key oncogenic driver in the majority of breast cancer. ER+ BC is the most common molecular subtype of BC. Management of ER+ breast cancer varies depending on menopausal status. For premenopausal women, the goal is to suppress estradiol production from the ovaries with surgical oophorectomy and/or aromatase inhibitors. In postmenopausal women, endocrine therapy (ET) serves to suppress estradiol production from sources other than the ovaries. During the menopausal transition, estradiol …

The U.S. Campaign Gacha System And Youth Underrepresentation, Rebecca Burrows, Eleanor Harris

Undergraduate Research Posters

This research investigates why young people remain underrepresented in elected U.S. offices and why youth voter turnout has historically remained low. Motivated by persistent shortcomings in U.S. youth turnout, the dominance of older elected officials, and recent high-profile victories by young mayoral candidates, this study asks whether young candidates (< 40) increase youth voter turnout in U.S. elections—and, if so, whether structural factors prevent these candidates from winning. Existing literature on descriptive representation and electoral inequality suggests that young candidates may energize youth voters yet face systemic disadvantages that hinder their success. This research contributes to the literature by exploring how the U.S. campaign finance system shapes young candidates’ electoral viability. Using a qualitative comparative case study design, we analyzed four large U.S. mayoral elections: two with victorious young candidates (Boston 2021; New York City 2025) and two where no candidate under 40 appeared on recent ballots (Los Angeles and Columbus). For each city, candidate eligibility rules, ballot requirements, party bylaws, primary election methods, and campaign finance laws were examined using publicly available legal and institutional documents. This approach allowed us to identify structural barriers while remaining open to unanticipated patterns across cases. Our findings reveal no explicit legal or party rules that impede young candidates. Instead, obstacles lie implicitly in the U.S. campaign finance system’s lack of limits on contributions, candidate spending, and the normalization of high-cost campaigning. These conditions allow older candidates—who are more likely to possess greater financial resources—to outcompete younger challengers, limiting youth descriptive representation and alienating youth from electoral politics. We conclude that youth underrepresentation is sustained less by overt legal barriers than by embedded systemic inequalities in campaign finance, an issue with broader implications for electoral integrity, representative democracy, and youth voter turnout in the United States.

Patterns Of Ovarian And Gonadotropin Hormones In Emerging Adult Oral Contraceptive Users, Summer Mcormond

Undergraduate Research Posters

Oral contraceptives (OCs) are often initiated during adolescence and emerging adulthood, a period of continued maturation of the hypothalamic–pituitary–gonadal (HPG) axis. Because hormonal exposure during this window may shape emotional, biological, and reproductive outcomes, it is important to understand the specific formulations young women take and the hormonal profiles these formulations produce. This study characterizes OC formulation features and measured hormone levels in young adult OC users (n = 30).

Ethinyl estradiol (EE) doses ranged from 0.01–0.035 mg (mean = 0.022 mg), with 70% using ≤0.02 mg. Pill regimens included 21/7 packs (83%), 24/4 packs (10%), and 84/7 regimens (3%). …

The wives of Henry VIII, in particular, are the victims of centuries of historically inaccurate fictional media. Six: The Musical is a modern musical spin on this centuries-old story, following the six wives of Henry VIII as they reclaim their narratives in a pop concert competition on who had …

Disarmament, Demobilization, And Reintegration And The Compensated Eradication Plan: The United States And Nato’S Counternarcotics Strategies In The War In Afghanistan From 2001-2005, Sungu A. Flottman

Undergraduate Research Posters

Starting in the late 1980s, Afghanistan was a major source of opium production, until the ban on opium in 2000, when Afghanistan’s share in the world’s supply of opium decreased. The United States’ intervention in Afghanistan in 2001 removed this ban on opium, which indicates that the United States may not have been prioritized stopping the narcotics trade. Consequently, the task of counternarcotics fell to the British. The question then becomes whether the British counternarcotics strategies were effective in curbing the Afghan narcotics trade, which may reveal the possible complacency behind the United States intervention in Afghanistan. Current research on …

Interpreting “Vampire” Burials In Medieval Eastern Europe, Arleen Chau

Undergraduate Research Posters

Since the early twentieth century, various atypical or deviant graves have been excavated across Eastern Europe, particularly in Poland. These discoveries have prompted much speculation, as the individuals were interred with items such as sickles placed over their necks or abdomens, along with other mortuary artifacts not considered normative compared to those found in typical community burials. Such practices suggest that these individuals were regarded as deviant or pariahs within their social contexts. Consequently, many have been quick to label these as “vampire burials,” interpreting them as measures intended to keep the dead from rising. However, this definition is problematic, …

Racism And Health In America: How Segregationist Policies Guided Tuberculosis Treatment In Virginia, Regina E. Mcrae

Undergraduate Research Posters

Racial inequality has shaped many aspects of American life, with health care among the most devastatingly affected. Structural racism has long driven disparities in housing, education, employment, the justice system, and, most critically, health care. Environmental racism, food deserts, inadequate medical access, and racial stressors have contributed to worse health outcomes, as seen during COVID-19. Chronic conditions like hypertension, asthma, and heart disease disproportionately affect Black communities, increasing morbidity and mortality.

In the early 20th century, these inequities were even starker as tuberculosis ravaged the Black population. While public health measures were implemented, it took decades before sanatoriums were built …

Did Our Prehistoric Ancestors Engage In Mortuary Practices?, Regina E. Mcrae

Undergraduate Research Posters

Abstract

Mortuary practice is defined as how humans dispose of and treat their dead. We are familiar with elaborate burials such as the entombment of pharaohs in the pyramids at Giza; Necropolises of the Valley of the Kings and Queens; the Mausoleum at Halicarnassus; the Taj Mahal in India; Viking funeral pyres on boats; and the modern jazz funerals of New Orleans. Caring for our dead is believed to be a modern concept, practiced by Homo Sapiens. However, archeological excavations and scientific analyses show burial practices predate modern man, practiced by our ancient ancestors such as Neanderthal, Homo Naledi, and …

Determining Genes Involved In Recovery From Chemotherapy In 4t1, Emt6, And Eo771 Breast Cancer Cells, Akash Jagdeesh, Joseph Landry Ph.D.

Undergraduate Research Posters

Breast cancer is one of the most common types of cancer, and often has poor prognosis. Traditional treatments for breast cancer include chemotherapy, which involves a chemical attack on all growing cells within the body. However, these treatments are not 100% effective, and patients might experience recurrence in their cancer months or years after achieving remission. Cancer cells can evade chemotherapy through five mechanisms: senescence, quiescence, cytoprotective autophagy, and apoptosis/necroptosis suppression. Prior studies have conducted CRISPR screens and experiments involving inhibition of epigenetic regulators, to alter the regulation of genes that can contribute to breast cancer chemotherapy resistance. This study …

The Myopia Epidemic: Integrating Genetic, Environmental, And Epigenetic Pathways To Define A Critical Window For Intervention, Pranavika Balaji

Undergraduate Research Posters

Myopia, or nearsightedness, has increased rapidly worldwide and is now a major public health concern caused by both genetic and environmental factors. Current understanding shows that too much near work, limited time spent outdoors, and prolonged screen use contribute to abnormal eye growth in individuals who may already have a genetic predisposition. At the molecular level, epigenetic changes and shifts in DNA activity, often influenced by environmental conditions, affect the signaling pathways that regulate eye development and may help explain why myopia is increasingly common among children. This paper synthesizes recent environmental, genetic, and epigenetic research to explain how these …

Fault Tolerant Adaptive Control Under Actuator Saturation For Robot Manipulators, D. J. López-Araujo, N. Alvarez-Jarquin, P. Borja, A. T. Becker

School of Engineering, Computing and Mathematics

In practice, actuators inherently have natural limitations that are often overlooked by theoretical control strategies, such as bounded output and discrepancies between calculated and actual responses. Consequently, reliable control techniques must be employed to ensure safe and dependable operation. We propose an adaptive control law for global regulation in the case of partial loss of effectiveness due to input faults. The proposed control strategy maintains the system at the desired configuration while accounting for the physical limitations of the actuators. Additionally, it is suitable for dealing with unknown parameters in the vector of gravitational forces, making it robust to these …

Angle-Based Formation Stabilization And Maneuvers In Port-Hamiltonian Form With Bearing And Velocity Measurements, Ningbo Li, Pablo Borja, Arjan Van Der Schaft, Jacquelien M.A. Scherpen

School of Engineering, Computing and Mathematics

This paper proposes a port-Hamiltonian approach for angle-based formation stabilization and maneuvers using bearing and velocity measurements with an underlying triangulated Laman graph. The corresponding port-Hamiltonian controller is designed using virtual couplings on the errors of angle constraints in angle space. Then, the angle constraints and agent actuators are mapped by the constraint Jacobian, which can be applied to other formation constraints. In addition, to avoid unavailable distance terms in the control law, an estimator is designed based on port-Hamiltonian theory and the property that energy is coordinate-free for different sensor modalities using bearing and velocity measurements, which permits our …
