Quantum Entanglement Correlations In The Proton On The Light-Front, Eric Kolbusz

Dissertations, Theses, and Capstone Projects

In this work we gather results on information theory applied to proton tomography. We start by analyzing the quantum entanglement of momentum, spin-flavor, and color degrees of freedom (d.o.f.) in the leading valence-quark state of the proton on the light front using standard information theoretical tools, leveraging model wavefunctions by Brodsky and Schlumpf to obtain numerical predictions. Light-cone perturbation theory allows us to introduce the one-gluon correction in the sub-leading Fock state and study the entanglement of the gluonic d.o.f. We find weak entanglement in the spatial d.o.f. of the valence quarks, and significantly stronger entanglement in the analogous d.o.f. …

Moralists Or Moral Hypocrites? Leveraging Moral Psychology And Social Identity Theory To Increase Support For Reparations Amongst White Americans, Andre Oliver

Dissertations, Theses, and Capstone Projects

The economic gains America made from the enslavement of Africans have long been considered its original sin; indeed, most people living today would agree that such an enterprise was morally depraved. Yet, due to moral opposition, many White Americans reject reparative policies (i.e., reparations) that are developed to remedy the damages done to African Americans by slavery and the subsequent continued discrimination. The present research attempts to address two broad hypotheses across four empirical research studies. The first hypothesis tests whether White Americans' rejection of reparative policies related to slavery and Black discrimination is inherently a moral objection to taboo …

Low-Resource Ecoacoustic Audio Classification, Enis Berk Coban

Dissertations, Theses, and Capstone Projects

Ecoacoustic monitoring via machine learning enables scalable analysis but is often constrained by labeled data scarcity, particularly in remote regions like the Arctic. This thesis confronts low-resource ecoacoustic audio classification by developing and evaluating complementary machine learning methodologies. We introduce EDANSA, the first publicly available, expert- labeled Arctic dataset of its kind, curated via novel active learning, alongside a baseline CNN. We systematically evaluate transfer learning, showing general audio embeddings effectively bootstrap classifiers for challenging Arctic sounds, significantly outperforming direct label mapping. Optimizing label utility, we investigate standard data augmentation and introduce novel audio data valuation via Shapley values, revealing …

Retinal Precursor Cell Enriched Multiomic And Pseudo-Time Analysis Of Developing And Reprogrammed Photoreceptors, Brendon M. Patierno

Dissertations, Theses, and Capstone Projects

The vertebrate retina is a complex tissue made up of seven major cell subtypes which during development must differentiate and localize into a highly organized structure. These neuronal cells do not regenerate if damaged or diseased, and the progressive deterioration of cone photoreceptor cells is the leading cause of age related blindness. Currently there are no cures for this disease, but one promising therapeutic avenue is cell transplantation research. If we can further elucidate the gene regulatory networks that define cone cell development, this knowledge could be applied to the generation of healthy cone cells in clinically relevant models.

Exploring The Role Of Ecological Traits In Shaping Spatial Patterns Of Genetic Diversity, Rilquer Mascarenhas Da Silva

Dissertations, Theses, and Capstone Projects

The field of comparative phylogeography aims at uncovering common underlying causes for shared patterns of diversity and diversification at the population level. However, it is now widely accepted that intraspecific genetic diversity patterns can differ considerably across co-occurring taxa due to ecological processes acting at the population level (and influencing individual movement and abundance). To model the processes underlying lineage diversification and demographic shifts in response to environmental changes, phylogeographers and population geneticists are now faced with the challenge of incorporating measurements of species ecological traits into their molecular studies. This dissertation aimed at investigating how different types of ecological …

Speaking From The Underground: Notes On Lois Elaine Griffith & The Nuyorican Poets Cafe Aesthetic, Joseph Anthony Cáceres

Dissertations, Theses, and Capstone Projects

Speaking from the Underground explores the work of Lois Elaine Griffith, an Afro-Caribbean diasporic visual and literary artist of Barbadian descent and one of the last surviving founders of the Nuyorican Poets Cafe, a Puerto Rican cultural institution grounded in Afro-Caribbean traditions located in Manhattan’s Lower East Side. In the common, cultural parlance, the Cafe has become synonymous with spoken word and slam poetry. Since 1973 it has been the place where artists of mostly African, Caribbean, Latinx descent gather to craft works centered around lived experiences to shape a language to counter a conventional understanding of history and a …

An Interpolating Regime For The Extreme Values Of A Random Zeta Model, Christine K. Chang

Dissertations, Theses, and Capstone Projects

We study the large values of a random model of the Riemann zeta function over short intervals. The extreme value statistics depend on the interval size: the log-correlated regime governs intervals of order one while the i.i.d. regime emerges over longer intervals. The main focus is to describe the transition between these two well-understood regimes as the interval varies in length. This thesis shows that there is an intermediate regime where the behavior of the zeta model’s maxima cannot be entirely captured by either extreme— i.i.d. or fully log-correlated. This suggests that the Riemann zeta function exhibits correlations around its …

Disability Theatre Communities: Engaging Artists And Audiences In Contemporary International Performance, Joseph Paul Hill

Dissertations, Theses, and Capstone Projects

“Disability Theatre Communities” examines how communities are constructed in, through, and around contemporary international disability theatre performances. It explores ideas of community formation and intersection across three case studies to elucidate the various ways in which disability theatre artists, productions, companies, and organizations attract, engage, and educate variable artist and audience communities. The project analyzes Rome, Italy’s Teatro Patologico and its Integrated Theatre of Emotion, a theatrical training program for neurodivergent performers; Wales-based writer, theatre-maker, and dramaturg Kaite O’Reilly, whose international collaborations center d/Deaf and disabled performers and foreground audience accessibility; and the biennial BIT (Blind in Theatre) International Festival …

Towards Automated Evolution Of Imperative Deep Learning Programs, Tatiana Castro-Vélez

Dissertations, Theses, and Capstone Projects

Software engineering (SE) is increasingly intersecting with data-centric domains such as machine learning (ML) and deep learning (DL). Similar to bugs in traditional software systems, defects can emerge in ML and DL systems. ML, including DL, systems are now widespread and rely on dynamic models defined by input data. Developers face the challenge of building dependable systems while addressing the demand for scalable software.

Efficiency is essential to support responsiveness with respect to ever-growing datasets. Traditional DL frameworks achieve scalability through deferred execution, enabling symbolic, graph-based deep neural network (DNN) computation. While efficient, this approach is error-prone, cumbersome, and difficult …

Toward A Generalizable Perceptual Hashing Framework For Image Manipulation Detection, Priyanka Samanta

Dissertations, Theses, and Capstone Projects

This thesis contributes to research in adversarial image manipulation detection. The primary motivation is the increasing need to verify digital images, especially for legal evidence, journalistic proof, or social media content—where manipulated or fabricated images can mislead, defame, or distort reality. A key application and contribution of this work is the development of eWitness, a blockchain application that generates and registers image provenance at capture time to enable independent verification of authenticity. The secret sauce behind the system is SmartHash, a novel and efficient perceptual hashing algorithm designed for real-world deployment in systems like eWitness. Unlike existing algorithms, SmartHash targets …

Non-Linear Heart Rate Variability: Investigating Cardiac Complexity Of Psychopathic Traits, Khaya A. Roach

Dissertations, Theses, and Capstone Projects

Psychopathy is a complex personality disorder characterized by distinct emotional and interpersonal deficits, and affects approximately 25% of the prison population and 4.5% of nonincarcerated populations. The manifestation of psychopathy can be understood through two distinct variants, each demonstrating unique etiological pathways and clinical presentations. Primary psychopathy is characterized by core interpersonal and affective deficits, including shallow emotions and manipulativeness, while demonstrating reduced autonomic responsivity and lower anxiety levels. Secondary psychopathy presents with higher levels of impulsivity, anxiety, and emotional dysregulation, showing stronger associations with various psychopathologies. Treatment outcomes also vary between the variants, with primary psychopaths typically showing poor …

The Salience Of Function Words In Implicit Statistical Linguistic Learning: An Erp Investigation, Daniel M. Schwartz

Dissertations, Theses, and Capstone Projects

Research has indicated that children and adults can implicitly learn language patterns; however, questions still remain regarding the role and nature of implicit learning, particularly of sequential patterns. Implicit statistical learning is a type of unconscious learning of sequential patterns, which may be especially relevant to phrase structure learning. Prior studies have highlighted the differential processing of function words (FWs), such as determiners, relative to content and nonsense words and have also pointed to particular neural response patterns (specifically, Anterior Negativity, or AN) to early syntactic violations. To date, there is relatively little work directly investigating the role of FWs …

Repurposing Atractylenolide Iii, A Natural Anti-Inflammatory Compound, For Alzheimer’S Disease, Angela M. Steele

Dissertations, Theses, and Capstone Projects

Alzheimer’s disease (AD) is a debilitating neurological condition ranked as the fifth leading cause of death in adults over the age of 65. Despite the severity, 98% of drugs have failed as treatments for AD. Current novel drug development approaches have been unable to produce a disease-modifying treatment as they often have a one-target approach, not accounting for the complex nature of the disease. One of the hallmarks of the disease, inflammation, may provide a better target for treatment because it interacts with multiple facets of the disease. Drug repurposing to identify compounds that mitigate inflammation in AD could provide …

Reduce, Replace, Reframe: How Civil Society Organizations Build Resilience In The Face Of Financial And Political Pressures, Merrill Sovner

Dissertations, Theses, and Capstone Projects

In order for civil society organizations (CSOs) to perform essential functions to support democracy and prevent democratic erosion, they must operate sustainably, maintaining resources and legitimacy to carry out their missions. CSOs experience financial and political pressures when resources and legitimacy are withdrawn. CSOs facing both pressures may reduce their activities, replace lost funding, or reframe their work to engage new audiences. How CSOs respond in the face of financial and political pressures has implications for their role in hindering democratic erosion. Yet civil society organizations weather these pressures in ways that are not straightforward; the most targeted organizations may …

Novel Machine Learning Methods For Quasar Variability And Strong Gravitational Lensing, Joshua Fagin

Dissertations, Theses, and Capstone Projects

Machine learning methods are well suited to handle the unprecedented data volume expected from upcoming wide-field surveys. The European Space Agency's Euclid telescope was launched in July 2023 and is expected to observe billions of galaxies at high resolution, including tens of thousands of strongly lensed galaxies. The Rubin Observatory Legacy Survey of Space and Time (LSST) will monitor tens of millions of quasars throughout its ten-year lifetime, thousands of which will be strongly lensed. This flood of data will enable measuring lens galaxy mass distributions and substructure, as well as probing quasar accretion disk structure and black hole properties …

Scripted For Surveillance: Parole Revocation Hearings And The Performance Of Procedure In New York, Kelsey G. Greeff

Dissertations, Theses, and Capstone Projects

This thesis examines parole revocation hearings in New York as complex performances that extend carceral control beyond prison walls. Drawing on a composite vignette from the Bronx parole court, it analyzes the interplay between procedural reform, constitutional due process, and neoliberal governance. Using a dramaturgical framework informed by Michel Foucault’s discourse analysis and Judith Butler’s theory of performativity, the study identifies four interrelated processes: the judge as director, who orchestrates hearings according to institutional priorities; normalization, where repetition embeds structural inequality as routine; type-marking, the classification of parolees into predefined roles through accumulated records and cues; and the extension of …

Transitional Justice And Counter-Productivity: A Case Study Of Serbia And Croatia, Michael F. Curry

Dissertations, Theses, and Capstone Projects

In the post-Cold War era, transitional justice emerged as a method to reconcile societies that had suffered large-scale human rights abuses through autocratic oppression and/or intra-state conflicts. During this time, the concept of what transitional justice meant and what problems it could resolve expanded exponentially. However, the empirical results of such initiatives have been mixed. Many states subject to transitional justice initiatives have failed to liberalize or develop domestic governance capacities. Why do transitional justice initiatives fail even under the most favorable conditions?

The most common answer to this question is that these initiatives are often ineffective, hindered by a …

Non-Perturbative Aspects Of Gauge Theories Through A Complex Parametrization, Antonina Maj

Dissertations, Theses, and Capstone Projects

This dissertation explores a complex matrix parametrization of four-dimensional non-Abelian gauge theories as a means of gaining analytical insights into (3+1)-dimensional QCD. The low-energy scale of non-Abelian gauge theories remains an elusive area of research even after decades of work. A key challenge lies in identifying physical, gauge-invariant degrees of freedom that are relevant to non-perturbative phenomena. In this dissertation we develop a complex parametrization of gauge fields on which gauge transformations act homogeneously, thereby enabling a manifestly gauge-invariant analytical formulation of the theory.

Chapter one constructs the complex gauge-invariant parametrization for gauge theories living on both complex projective space …

Collaborative Memory And Metamemory: The Impact Of Normative And Informational Motivations On Conformity, Karen Rodriguez

Dissertations, Theses, and Capstone Projects

Collaborative memory studies have typically explored the cognitive mechanisms that underlie differences between collaborative and individual memory performance. Despite the social nature of collaboration, few studies have examined the impact of social motivations on collaborative memory. When retrieving information with groups, people may not only be motivated by a desire to be accurate (i.e., informational motivations), but may also be guided by social norms (i.e., normative motivations), such as prioritizing agreeability or alignment with group members (Cialdini & Goldstein, 2004). Similarly, retrieving information with others may also prompt individuals to reflect more on their own memory processes. However, few studies …

Medication Adherence Among Partnered, Sexual Minority Men Living With Hiv: What’S Love, Interdependence And Comorbidities Got To Do With It?, Kendell M. Doyle

Dissertations, Theses, and Capstone Projects

Sexual minority men (SMM) report higher incidence and prevalence rates of HIV infection relative to their heterosexual counterparts. The burden of HIV infection has garnered research attention focused on HIV risk reduction and HIV disease management (such as medication adherence). More recently, attention has been paid to the association of comorbid chronic health conditions and ART adherence among people living with HIV (PLWH) more broadly. Yet, limited attention has been paid to the association of comorbidities among SMM living with HIV specifically, despite the high rates of HIV among this population and various other risk factors that put SMM at …

Characterization Of The Attentional Profile In Women And Girls With A Fragile X Premutation Allele, Shira Russell-Giller

Dissertations, Theses, and Capstone Projects

The fragile X premutation (PM), characterized by 55 to 200 CGG repeats in the FMR1 gene, is associated with diverse clinical outcomes, including cognitive and neuropsychiatric changes. Despite most individuals with a PM presenting without overt clinical symptoms, adults face increased risks for conditions associated with a PM, including higher rates of attention and executive difficulties. This dissertation investigates the developmental trajectory of attention and executive functioning changes in females with a PM using a series of prospective studies employing the Attention Network Test (ANT). Study 1 re-analyzed prior data on sustained attention in women with a PM, revealing significant …

Relevant Deformations Of Brane Brick Models, Georgios P. Goulas

Dissertations, Theses, and Capstone Projects

The thesis studies relevant deformations of 2d gauge theories with $\mathcal{N}=(0,2)$ supersymmetry, realized on the worldvolume of D1-branes probing toric Calabi-Yau 4-folds. Brane brick models are the primary means for engineering such theories and streamlining their connection to geometry. In this thesis, we relevant deformations of brane brick models, focusing on a specific class of deformations in which the initial and final theories are both described by brane brick models. Relevant deformations serve as an additional, systematic way of generating these theories, as well as uncovering connections between them. Within the framework of brane engineering, these deformations acquire a geometric …

Asian American Artists, Improvisation, And Collaboration, Johnna Wu

Dissertations, Theses, and Capstone Projects

The purpose of my dissertation is to explore how contemporary Asian Americans artist-performers have formulated their identities through collaborations with the Association for the Advancement of Creative Musicians (AACM). The project addresses issues in the existing literature on this topic and provides an alternative framework of cosmopolitanism to understanding the multidimensional aspects of artistic collaborations. The dissertation examines the history of the AACM and the Asian American improvisers and reveals ideological differences among its members on how music should reflect their identities. These histories paved the way for the artist subjects of my three case studies: Miya Masaoka, Vijay Iyer, …

Some Puzzles Concerning Gujarati Nominalized Verbs In Before And After Sentences, Priya P. Patel

Dissertations, Theses, and Capstone Projects

Aspect, which relates events to time periods, interacts in complex ways with temporal operators. This complexity is exemplified in the Gujarati language, where certain imperfective nominalized verbal forms are considered unacceptable with the temporal operator pachi (after) but not with pehlaa (before). This paper aims to shed light on this semantic unacceptability by combining insights from prior studies relating to aspect in other Indo-Aryan langauages with previous work done on English before and after.

Investigating The Behavior Of Dwarf-Hosting Cosmic Filaments In Regions Of Average Density Within The Universe, Manuel E. Ramirez Hernandez

Dissertations, Theses, and Capstone Projects

The cosmic web is the large-scale structure of the universe, composed of elongated, overdense areas held together by gravity known as cosmic filaments. Within these filaments, dwarf galaxies are ubiquitous and make for excellent laboratories due to their small size. to determine the effects of cosmic web structures on dwarf galaxies. In this thesis, I laid the groundwork to investigate whether dwarf galaxy populations vary across different types of filaments. Filaments were extracted from the gas density field in the New Horizon simulation at $z=0$ using the topological feature finder DisPerSE. I determined the distances of galaxies to their nearest …

Unveiling The Vital Role Of Blue Carbon In Mangroves: Understanding Environmental Influences, Jahnelle Howe

Dissertations, Theses, and Capstone Projects

Mangrove ecosystems provide essential ecological services, including carbon sequestration, coastal protection, and heavy metal retention. However, their resilience and functionality are increasingly influenced by hurricanes, climate variability, and anthropogenic contamination. This dissertation integrates three research efforts examining mangrove canopy dynamics, carbon storage, and heavy metal contamination in two Puerto Rican mangrove systems: La Parguera and Laguna Grande.

Using remote sensing techniques (LiDAR and NDVI analysis), we assessed the impact of Hurricane Maria (Category 4, 2017) on mangrove canopy structure and vegetation health. Results revealed significant canopy height loss, with greater damage at Laguna Grande, where pre-storm canopy height and human …

Creative Coding Communities: Exploring The Relationship Between Scratch Use And Child Well-Being, Nikita Khalid

The data were used to construct user …

Spirometry: For The Winds In Us, Kendall Allison

Dissertations, Theses, and Capstone Projects

Spirometers are devices used to measure lung capacity. This capstone is a creative study of what restores our breathing aptitude as a response to the suffocating and alienating consequences of whiteness for people racialized as white. The project is a sequence of lyric essays. The first lyric essay frames whiteness as a condition of exile and examines the cultural and emotional currents that shore it up. I use exile as a frame to emphasize the intensity of the spiritual and cultural alienation that people racialized as white experience. I also contextualize the dis-ease of suicide in my own lineage, and …

Parvalbumin Interneuron-Oligodendrocyte Interactions In The Infralimbic Cortex Promote Extracellular Plasticity Mechanisms After Safety Learning, Lucy Emma Denholtz

Dissertations, Theses, and Capstone Projects

The ability to differentiate between threat and safety cues is essential for adaptive behavior, yet this process is disrupted in psychiatric disorders, such as post-traumatic stress disorder (PTSD), where safety cues fail to downregulate fear expression. To better understand the neurobiological mechanisms of safety learning, I investigate how safety conditioning vs contextual fear conditioning modify behavioral and cellular mechanisms in the infralimbic (IL) region of the medial prefrontal cortex (mPFC) at several time points after learning. Through this work, I identify a novel mechanism whereby safety learning promotes learning dependent neuro-glial interactions that promote conditions for plasticity in the mPFC. …

Nonlinear Physics Of Parity-Broken Fluids, Sudheesh Srivastava

Dissertations, Theses, and Capstone Projects

This thesis explores parity-breaking mechanisms, nonlinear wave phenomena, and localization transitions across different physical contexts. First, we examine modulation instability in parity-breaking systems, deriving modified nonlinear Schr¨odinger equations that reveal direction dependent instabilities. Next, we investigate wave turbulence, demonstrating numerically that parity-breaking dispersion significantly alters turbulent cascades and modifies their statistical properties. Lastly, we analyze localization in quasiperiodic tight- binding model based on polariton condensate lattice. Collectively, these studies illustrate the universal role of symmetries and nonlinear interactions in shaping macroscopic behaviors, facilitating interdisciplinary insights.
