Interfacial Defect Properties Of High-Entropy Carbides: Stacking Faults, Shockley Partial Dislocations, And A New Evans-Polanyi-Semenov Relation, Samuel E. Daigle, Stefano Curtarolo, William G. Fahrenholtz, Jon Paul Maria, Douglas E. Wolfe, Eva Zurek, Donald W. Brenner

Materials Science and Engineering Faculty Research & Creative Works

Using first principles calculations, {111} intrinsic stacking fault (ISF) energies in groups IVB, VB, and VIB high-entropy transition metal carbides (HETMCs) are shown to be predictable from an optimized rule of mixtures based on the atomic arrangement near the stacking fault. A composition-independent linear relationship is demonstrated between the ISF energies and the unstable stacking fault (USF) energies along the (112¯){111} γsurface slip path. This relationship represents a new application of the Evans-Polanyi-Semenov principle by treating the ISF and USF energies as analogous to the heat of reaction and transition state barrier in chemical reactions. Further, a full defect energy …

Advancing Marine Animal Movement Studies Using An Open Innovation Framework, Jacob Levenson

Graduate Doctoral Dissertations

This dissertation investigates the application of open innovation to migratory marine animal movement studies, addressing critical challenges in understanding, managing and ultimately conserving highly mobile and migratory species (HMMS). The species examined herein, including manta rays, sea turtles, and marine mammals, face threats including habitat disruption and behavioral changes to adapt to anthropogenic stressors. Traditional monitoring techniques, while valuable, are often costly, limited in scale, and protected by proprietary intellectual property, all of which decrease accessibility. Ambitious conservation goals, such as protecting 30% of the ocean by 2030, require more data that are indubitably sharable and thus will need to …

New Mathematical Approaches To Ultra-Cold Atoms, Joanna Ruhl

Graduate Doctoral Dissertations

This dissertation addresses three main themes: cold atoms, integrability, and number theory. In this dissertation we present novel approaches to four models, each of which touches on at least two of the three themes. At the intersection of cold atoms and integrability, we present a Lagrange bracket formalism that allows for exact computation of initial quantum fluctuations of soliton breathers which previously could only be estimated numerically, and the advance in software tools developed in Python to facilitate studies of two-dimensional disc breathers. At the intersection of integrability and number theory, we present a propagator for the Newman-Moore, or triangular …

Through Legitimate Dissent, The Supreme Court Repairs Itself, Afnaan A. Qureshi

Theses

The decisions of the Supreme Court of the United States, along with its reasoning, influence the direction and scope of historical events. Through an analysis of landmark dissents from four of the worst Supreme Court decisions, Curtis’ dissent in Dred Scott v. Sandford (1857), Harlan’s dissent in Plessy v. Ferguson (1896), Holmes’ dissent in Abrams v. United States (1919), and Murphy’s dissent in Korematsu v. United States (1944), we can take steps towards catalyzing its self repair by stepping away from digital echo chambers and engaging in legitimate dissent. The four cases marked turning points in the efforts to protect …

A Prototype High Power Dc-Dc Converter For Regulating Generator Output Voltage In A Series Hybrid Electric Vehicle, Alex Currie

Theses

As fully electric and hybrid electric vehicles become more commonplace, a strong incentive for innovation in electric powertrain technology has been created. Though the instantaneous power available from an electric motor may appeal to consumers of powersports vehicles, this has been an area with relatively little advancement towards electric architectures. One primary concern of electrifying such a platform is the need for large battery packs that tend not to perform well in the harsh weather conditions often seen in powersports such as snowmobiling. As such, hybrid electric architectures may prove to be a successful middle ground between fossil fuels and …

The Evolution Of The Divine Feminine: How Religious Upheaval Changed Female Devotions, Nicole M. Honeycutt

Institute for the Humanities Master's Papers, Projects, and Capstones

The transformation in the depiction of women in Christian religious art from pre-Reformation through the Counter-Reformation mirrored and molded shifting theological, cultural, and gender paradigms. While much scholarship has addressed the symbolic and doctrinal significance of female figures in sacred imagery, less attention has been paid to how such portrayals influenced women’s own devotional experiences and sense of spiritual agency. This study argues that the religious imagery was not merely a passive reflection of male-dominated ecclesiastical values, but an evolving communicative medium through which women could engage with and reshape their spiritual roles. By analyzing key artworks, patronage trends, and …

Out Of The Blue: A Case Of Acute Limb Ischemia In A Healthy Young Woman, Julian Coz, Melanie Angelo

Rowan-Virtua Research Day

Acute limb ischemia (ALI) is a critical condition caused by arterial occlusion, often due to thrombotic or embolic events in atherosclerotic vessels. Early diagnosis and intervention are essential to prevent limb loss and complications. While typically seen in patients with known vascular risk factors, ALI can also affect individuals without them.

We present a case of a 49-year-old female with sudden-onset left foot pain and paresthesia, highlighting the importance of recognizing ALI in seemingly healthy patients. Despite the absence of typical risk factors, imaging revealed significant atherosclerosis and arterial occlusion, leading to the diagnosis of ALI. This case emphasizes the …

In the ED, he had elevations of his CK and creatinine and required hospital …

Case Report: Dysphagia In Inclusion Body Myositis Leading To Respiratory And Gastrointestinal Complications, Veroneka Mikhail, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Inclusion body Myositis (IBM) stands as a rare and complex neuromuscular disorder (NMD) characterized by progressive muscle weakness and atrophy. Among its cardinal symptoms are dysphagia and respiratory distress, which are the most common cause of death in this disease. While the differential diagnosis of respiratory distress is vast and includes aspiration, pneumonia, acute coronary syndrome, emphysema, and congestive heart failure, a clinician should recognize that respiratory distress can also be secondary to dysphagia in NMDs like IBM and can quickly become life threating. Here we present the case of a 68-year-old female with a history of IBM who presented …

This case report highlights the presentation of myoclonic jerking in a 77-year-old male with a history of sleep apnea and obesity, who presented to the emergency department with hypoxia and elevated carbon dioxide levels. Despite the lack of neurological deficits, the patient experienced intermittent myoclonic jerks of his hands, which were attributed to CO2 retention. The report underscores the importance of recognizing myoclonic jerking as a potential sign of …

Dural Venous Sinus Thrombosis: Be Careful When You Sneeze, Arsam F. Nadeem

Rowan-Virtua Research Day

Dural venous sinus thrombosis (DVST) is a rare but potentially life-threatening condition that accounts for approximately 0.5–1% of all strokes. It is often associated with hypercoagulable states, infections, malignancies, and systemic inflammatory diseases. Clinical presentations are highly variable and can include headaches, focal neurological deficits, seizures, and altered mental status. Given its nonspecific symptoms, DVST remains a diagnostic challenge. This report presents a case of a young male who developed a persistent headache and had transient speech changes and was ultimately diagnosed with a dural venous sinus thrombosis.

Cannabinoid Hyperemesis Syndrome Induced Pneumomediastinum In An Adolescent, Julian Coz, Christopher Schwartz, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Cannabinoid hyperemesis syndrome (CHS) is a condition characterized by cyclic episodes of severe nausea, vomiting, and abdominal pain in individuals with chronic cannabis use. Despite its increasing recognition, CHS remains underdiagnosed, particularly in adolescents, and can be associated with a range of complications, some of which are potentially life-threatening. One such complication is spontaneous pneumomediastinum (SPM), a rare but serious condition where air accumulates in the mediastinum without any clear traumatic cause. Although SPM is typically benign, it can present with significant respiratory distress and requires prompt identification and management. Here we present the case of an 18-year-old patient with …

Does Sports-Specialization Increase The Risk Of Injury In Youth Athletes?, Kinjal Shah

Rowan-Virtua Research Day

Sports specialization, defined as intensive, year-round training in a single sport for more than eight months per year, has become increasingly prevalent among youth athletes. While it is often pursued with the goal of elite performance, early specialization may increase the risk of both physical injuries and psychological strain. This risk is especially pronounced in individual sports such as swimming and tennis, where early and focused training is frequently encouraged. This study explores the association between early sports specialization and injury risk in young athletes, with the goal of identifying contributing factors and informing prevention strategies. Evidence suggests that while …

Exploring The Effects Of Target Race, Gender, And Weight On Pain Perception, Catherine Awad, Theresa Miller, Azer Tuerxuntuoheti, Peter Mende-Siedlecki

Rowan-Virtua Research Day

Healthcare equity is an essential right, and while the quality of care is assumed to be uniform, notable disparities in care are associated with factors of race, gender, and weight-particularly in the domain of pain evaluation and care. In experimental work, target race and gender have varying, and interacting effects on visual thresholds for perceiving painful expressions. Racial bias in pain perception is well established as participants see pain on black faces less readily than pain on white faces; gender also impacts pain treatment, where women are susceptible to having their pain discredited. Across two experiments, the influence of weight …

This study assessed the accessibility of wound care for the unhoused population in South Jersey, where approximately 2,607 individuals experience homelessness on any given night. Our research identified significant barriers to wound care access, including transportation limitations, lack of identification documents, absence of a physical mailing address, and language barriers. Data analysis revealed concerning trends: a 24% increase in New Jersey's homeless population in 2024, with Black/African American individuals representing 49% of the homeless population despite comprising only 12% …

A Review Of Sutures And The Prospective Applications Of Nanofiber Technology In Suture Engineering, Hanna Brancaccio, Dominique Hassinger, Vincent Beachley

Rowan-Virtua Research Day

Introduction: Suturing is a method to close surgical or traumatic wounds to promote healing. The ideal suture should have high tensile strength that loses strength at the same rate as the healing tissue gains strength, be easy to handle and form secure knots, induce minimal inflammation, and stretch/recoil according to wound contraction. While there are suture materials available for use in various procedures that fulfill most requirements, no one suture possesses every desirable characteristic, and limitations are still prevalent. Nanofiber geometry has a well-known ability to modulate cell morphology, attachment, gene expression, extracellular matrix production, and macrophage polarization in …

Cardiovascular disease (CVD) is a leading global cause of mortality, but South Asians experience a disproportionately high burden of disease, often developing CVD at younger ages and with lower body mass indices compared to other populations. This project explores the underlying genetic and lifestyle factors contributing to elevated cardiovascular risk in South Asians, aiming to highlight the need for targeted prevention strategies and policy reforms.

A literature review was conducted using peer-reviewed studies, meta-analyses, and reviews published between 2007 and 2024. After screening 47 initial articles, 18 were selected for analysis based on their relevance to genetic and lifestyle risk …

Scoping Literature Review: The Role Of Leptin In Autism Spectrum Disorder (Asd) And Associated Obesity, Diana B. Riestra, Andrea Iannuzzelli

Rowan-Virtua Research Day

Overweight and obesity (OW/OB) are significant concerns among individuals with Autism Spectrum Disorder (ASD), yet the underlying causes remain unclear. Emerging evidence points to metabolic and hormonal factors—particularly leptin, a hormone involved in appetite regulation—as potential contributors. This scoping review examined five key studies from 2003 to 2024 that investigated the relationship between leptin and ASD in overweight populations. Across studies, individuals with ASD consistently exhibited elevated leptin levels compared to controls. While some findings also noted changes in other adipokines, such as lower resistin or progranulin, leptin was the most consistently dysregulated. These patterns suggest systemic alterations in energy …

Case Report: Pigtail Suprapubic Catheter Placement In A Patient With Acute Urinary Retention And Abdominal Mesh, Clara Keum, Zamran Masih, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Acute urinary retention (AUR) is a urological emergency that requires immediate bladder decompression and management of the underlying condition to prevent further complications such as urinary tract infection and renal failure. When standard urethral catheterization is not feasible, a suprapubic catheter can be used to achieve adequate bladder drainage. However, in patients with structural or anatomical challenges, such as the presence of surgical mesh, suprapubic catheter placement can be difficult. This case report presents the successful placement of an 8.5 French pigtail catheter and urinary drainage in an 86-year-old male with abdominal mesh who presented with AUR.

Development Of Saddlepoint Methodologies For Sparse Sample Multiple Parameter Generalized Linear Models And Correlated Data Scenarios, Christopher Johnson

All Graduate Theses and Dissertations, Fall 2023 to Present

Parameter estimation using maximum likelihood techniques may be biased when sample sizes are small, event rates are low, or otherwise sparse counts exist in a parametric model. This in turn may lead researchers to draw invalid statistical conclusions when conventional methods are utilized. The saddlepoint approximation has potential to lessen the degree of bias in sparse data conditions through its use of moments beyond the mean and variance, which allows for more accurate approximations using a smaller number of observations. We propose two novel saddlepoint methods for use in practical analysis scenarios, as an alternative to maximum likelihood estimation. First, …

The 100-Year Life And The New Family Law, Naomi Cahn, Clare Huntington, Elizabeth S. Scott

Faculty Scholarship

This chapter reflects on the future of family law in an era of longer lives. Our analysis leads us to conclude that the 100-year life is indeed likely to have an impact on the nature, scope, and definition of family law, but that families will continue to function as the primary setting for intimacy and for caregiving and caretaking, whatever form those families take. Further, the importance to both individual and social welfare of family support throughout life points to a need for reform of current family law doctrine. The impact of longer life on doctrines regulating the relationship of …

Making Tabby, Making Place: Examining A Gullah Geechee Wattle And Tabby Daub Dwelling Through Thin Section Analysis, Jacob E. Hamill

Graduate Masters Theses

Tabby is a building material made from lime, sand, oyster shell, and water that is geographically associated with the Sea Islands of South Carolina, Georgia, and Florida. This material was used from the early 18^th century to end of the American Civil War to construct all-manner of buildings in the Sea Islands region. Enslaved African descendant communities constructed wattle and tabby daub dwellings within plantation landscapes, and these settlements are interpreted as spaces where enslaved people exercised greater spatial autonomy.

This thesis analyzes the remains of a wattle and tabby daub structure located on what was once Old Fort …
