Hetero-Cisgender Rituals: The Oppression Of Sexual- And Gender-Minoritized People, Bertha A. Ben Khallouq

Graduate Thesis and Dissertation post-2024

Among the groups that experience health inequalities in the United States, sexual- and gender-minoritized people figure prominently. Medical practitioners are tasked with alleviating these health inequalities, and it has been suggested that through the education of new physicians, we can decrease these inequalities. This perspective, however, neglects that medical students are social actors and their socialization begins long before medical school. In the present study, I develop a framework for understanding hetero-cisgender rituals that medical students experience and participate in before starting their medical training. I answer three research questions: (1) To what extent do medical students witness hetero-cisgender rituals? …

A Mathematical Modeling Approach To Investigate The Impacts Of Post-Infection Mortality And Partial Immunity On Disease Endemicity, Brendan M. Shrader

Honors Undergraduate Theses

A number of infectious diseases cause post-infection conditions or complications, such as COVID- 19, Q fever, and Polio. These conditions result in recovered individuals having a higher mortality rate than susceptibles, and this can impact disease dynamics. An existing mass-action model in the literature that incorporated post-infection mortality was shown to have limit cycles, or persistent oscillations, in the infected population. To better understand what causes these limit cycles, we develop and analyze a new epidemiological model with standard incidence. We show standard results, including the existence, uniqueness, and stability of the disease-free and endemic equilibria, and we rule out …

Comparative Analysis Of Estimation Techniques On Human Performance In Seek-And-Place Tasking, Adam J. Wehr

Graduate Thesis and Dissertation post-2024

Accurate parameter estimation is fundamental to statistical modeling, shaping the validity of inference, prediction, and decision-making. Although Maximum Likelihood Estimation (MLE) and Bayesian methods are well established theoretically, their performance relative to alternative estimators in small-sample, skewed-data contexts remains less clear. This thesis addresses this gap through a systematic evaluation of estimation techniques applied to human response time data from a controlled seek-and-place jigsaw puzzle task, where distributions are characteristically right-skewed.

A performance-modified lognormal model was developed to capture the relationship between task complexity and response times. Four estimation approaches were investigated: MLE, Method of Moments (MoM), Bayesian estimation under …

Least Squares Support Vector Data Description With Adaptive Optimizers, Daniel Markwei

Graduate Thesis and Dissertation post-2024

One-class classification has emerged as a powerful technique for data description, enabling a model to learn exclusively from data belonging to a single (target) class. By focusing solely on patterns within this class, this classification procedure is implemented in order to successfully assess whether incoming input deviates or is part of the target group. This approach develops a sophisticated understanding of the defining characteristics of the target data in relation to other groups. Consequently, any data point that deviates from the target group is flagged as an anomaly because it diverges from the learned distribution. One way to explore the …

Fast Differentiable Projection Layers Onto High-Dimensional Polytopes For Large-Scale Predictive Modeling, Camilo Gomez

Graduate Thesis and Dissertation post-2024

Recent trends in statistical machine learning have revealed the power of integrating optimization procedures as first-class components within end-to-end large-scale predictive systems. These structured computations—often formulated as projections onto geometric objects like polytopes—enable models to inject domain-specific inductive biases and enforce desirable properties in the learned representations useful in downstream classification or regression tasks. This dissertation explores the role of such projections in enhancing learning performance and generalization, particularly in the context of predictive modeling with data intensive systems.

Motivated by the limitations of traditional surrogate loss functions such as logistic loss for classification or cross-entropy for multiclass problems, this …

Domain-Constrained Clustering: A Two-Stage Framework For Muscle Fiber Type Identification, Fanchao Yi

Graduate Thesis and Dissertation post-2024

This dissertation introduces a novel Two-Stage Clustering Framework for the automated identification of human skeletal muscle fiber types using fluorescence microscopy image intensity data. By integrating two complementary clustering methods, this framework overcomes the subjectivity and labor-intensive nature of traditional manual methods, offering an objective and efficient solution for large-scale muscle physiology research. The initial framework combined Density Peaks Clustering (DPC) with a Gaussian Mixture Model employing a t-distribution (GMM-t). This version was validated by comparing its clustering results with manual counts at the individual subject level. We successfully applied this framework in two published studies \cite{brennan2020,hinkley2023}, demonstrating its practical …

A Unified Thermodynamic Framework For Regime Discovery, Entropy-Aware Optimization, And Emergent Leadership In Flocking Systems, Victor Nkwocha

Graduate Thesis and Dissertation post-2024

This thesis presents a unified framework for modeling, optimizing, and analyzing collective behavior in flocking systems through a thermodynamic and statistical lens.

The second study introduces the Organic Adaptive Flocking Algorithm (OAFA), a biologically inspired, entropy-aware extension of the Boids model. OAFA dynamically adjusts rule weights based on local entropy signals and is optimized via a multi-objective NSGAII framework to balance cohesion, separation, energy efficiency, and disorder. Results show that entropy …

Sparse Low-Rank Tensor Logistic Regression With Applications In Neuroimaging, Michael Hurtado

Graduate Thesis and Dissertation post-2024

Discriminant analysis techniques, while extensively studied for traditional datasets, have rarely been adapted to address the complexities of high-dimensional tensor data. Recent advances in tensor decomposition, as reviewed by Burch et al. (2025), highlight methods such as CP, Tucker, HOSVD, and t-SVD, which offer robust frameworks for handling multi-dimensional biomedical data, including neuroimaging. In this paper, we propose a novel approach that integrates low-rank regularization techniques with tensor structures to tackle high-dimensional matrix and tensor data. Building on the Multi-Projection Optimal Scoring Discriminant Analysis (ROSDA) method by Huang & Zhang (2020), which employs multi-directional projection pursuit for robust classification, our …
