Structure Functions For The Inclusive Semileptonic B-Quark Decay At Nnlo: A Semi-Analytic Calculation, A. Broggio, B. Capdevila, A. Ferroglia, P. Gambino

Publications and Research

We present a study of the inclusive charmless semileptonic b decay, b → Xuℓv at next-to-next-to-leading order (NNLO) in perturbative QCD, with the primary aim of extracting the hadronic structure functions Wi at NNLO. The analysis is based on a numerical calculation of the relevant kinematic distributions using a phase-space slicing method to handle infrared-sensitive contributions from real gluon emissions. We use known results from Heavy Quark Effective Theory and Soft-Collinear Effective Theory to extract the singular terms and construct a model for the regular contributions to the structure functions at NNLO, then perform a fit to the …

The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood. Here, we integrate satellite observations, in situ hydrological records and reanalysis data to examine recent drivers of the Caspian water loss. We show that total river inflow to the Caspian Sea has declined significantly, primarily due to reduced discharge from the Volga River. At the same time, precipitation over the basin has remained broadly stable, while …


Enhancing Digital Literacy Programmes For Advanced Search Skills Of Adult Public Library Patrons, Santel Smit Ms., Nikiwe G. Momoti Dr Jun 2026

Enhancing Digital Literacy Programmes For Advanced Search Skills Of Adult Public Library Patrons, Santel Smit Ms., Nikiwe G. Momoti Dr

Urban Library Journal

Digital literacy enables individuals to confidently engage with electronic devices and digital resources. While many adults use these tools to search for information, some still lack the essential skills to do so effectively. This pragmatic paper investigates the basic digital literacy skills of adult patrons at Adriaanse Public Library in Cape Town. Framed by SCONUL Seven Pillars of Information Literacy through a Digital Literacy “lens”, we employed a sequential mixed-methods approach, combining quantitative pre- and post-tests with qualitative interviews among 30 purposively selected participants. Quantitative data was analyzed statistically while thematic analysis was used for qualitative data. The findings revealed …


Bullying, Early Sexual Debut, And Sexual Health Behaviors Among Adolescents In New York City, Valentina I. Ramirez Jun 2026

Bullying, Early Sexual Debut, And Sexual Health Behaviors Among Adolescents In New York City, Valentina I. Ramirez

Dissertations and Theses

Adolescent sexual and reproductive health remains a critical public health priority in the United States, particularly given the persistent burden of HIV and sexually transmitted infections (STIs) among young people. Adolescents and young adults account for a disproportionate share of STI cases, reflecting ongoing gaps in prevention, early detection, treatment, and equitable access to sexual health care and services. These patterns are shaped not only by individual behaviors but also by broader social, structural, and developmental contexts that influence adolescents’ opportunities to engage in preventive sexual health care.

This dissertation examined associations between early sexual debut, experiences of bullying, and …

Utilizing self-determination theory and language ideologies as theoretical frameworks, this study captures the motivating factors and challenges of 15 mid-career bilingual teachers across NYC. Findings indicated that relationships with students and colleagues, professional growth, supportive administrators, and alignment between language ideologies and program structures served as motivating factors to remain in the profession by reinforcing teachers’ sense of relatedness, competence, and autonomy. Motivating factors that supported …


Stories Of Social Transformation And Resistance: A Narrative Inquiry Into The Culturally Sustaining Practices Of Teachers Of Color, Daniel E. Hernandez Jun 2026

Stories Of Social Transformation And Resistance: A Narrative Inquiry Into The Culturally Sustaining Practices Of Teachers Of Color, Daniel E. Hernandez

Theses and Dissertations

In the United States, persistent inequities in schooling have intensified the need for asset-based  frameworks, such as culturally sustaining pedagogies (CSP), to support students from  communities that have been historically racialized and minoritized. At the same time, growing  political and social resistance to practices of diversity, equity, and inclusion (DEI) has created  barriers for schools and teachers seeking to implement culturally responsive approaches to  teaching and learning. Using narrative inquiry, this dissertation explores the stories of three culturally  sustaining teachers of color to understand how they enact resistance and pursue social  transformation in their classrooms and schools. Through an examination …


Kitchen Table Press: A Case Study Of Regression To The Neoliberal Mean, Alaina Disalvo Jun 2026

Kitchen Table Press: A Case Study Of Regression To The Neoliberal Mean, Alaina Disalvo

Dissertations, Theses, and Capstone Projects

This thesis examines the idealistic founding of Kitchen Table: Women of Color Press in 1980 and its slow downfall, culminating in the cession of ownership of the Press to a university in 1992. It traces the ideological development of Kitchen Table Press’s key founders, Barbara Smith and Audre Lorde, and their respective relationships to the ideologies of other renowned feminist figures of the era, specifically June Jordan and Adrienne Rich. It examines the history of the Press through historical, intersectional, affective, and socialist lenses. This thesis argues that neoliberal pressures can bend even the most radical organizations away from their …


Revolutionary Petunias In The Hallways: Adultification, Identity, And Black Girls’ High School Experiences, Renee Niles Jun 2026

Revolutionary Petunias In The Hallways: Adultification, Identity, And Black Girls’ High School Experiences, Renee Niles

Dissertations, Theses, and Capstone Projects

This thesis examines how adultification, the racialized misperception of Black girls as more mature, responsible, and self-sufficient, shapes high school experiences and identity development. Using Constructivist Grounded Theory and Black feminist epistemology, the study draws on interviews with eight Black women to explore how these experiences are interpreted over time. The study conceptualizes adultification as a form of developmental governance, an ongoing structural process that regulates perception, behavior, and identity from adolescence into adulthood.


Radiotheranostics For Gynecological Pathologies, Joni Sebastiano Jun 2026

Radiotheranostics For Gynecological Pathologies, Joni Sebastiano

Dissertations, Theses, and Capstone Projects

Molecular imaging, specifically positron emission tomography (PET), is vital for detecting disease and understanding its biological makeup. The exploitation of radiolabeled antibodies for PET imaging has proven to be indispensable to the field of molecular imaging over the last several decades. The development of radioimmunoconjugates for use in immunoPET has not only allowed for the sensitive, specific, and high-resolution detection of disease, but has also enabled a deeper understanding of the disease biology, ultimately guiding more personalized therapeutic strategies. Most typically, this technology is harnessed for the diagnosis and treatment of cancer, however more recently, the field has explored the …


Music Appreciation In Cochlear Implant Users: A Questionnaire, Hanna Davidson Jun 2026

Music Appreciation In Cochlear Implant Users: A Questionnaire, Hanna Davidson

Dissertations, Theses, and Capstone Projects

Cochlear implants provide significant benefits for speech perception in individuals with severe to profound hearing loss; however, music perception and appreciation remain challenging due to limited spectral and temporal resolution. This study examined music appreciation in post lingually deafened adult cochlear implant users, focusing on changes in enjoyment, listening behaviors, and subjective experiences following implantation. Sixteen adults completed a 36-item questionnaire assessing pre- and post-implant music engagement, perceived sound quality, and emotional responses to music. Quantitative data were analyzed using descriptive statistics and inferential statistics, and qualitative responses were analyzed thematically.

Results indicated a moderate decline in music enjoyment following …


How Temporal Integration And Complexity Drive Musical Enjoyment, August Miller Jun 2026

How Temporal Integration And Complexity Drive Musical Enjoyment, August Miller

Dissertations, Theses, and Capstone Projects

Music is a type of aesthetic stimulus that unfolds dynamically over time. Combining approaches from previous research on musical preferences and research on spatial integration as a driver of visual aesthetic appreciation, we investigated how the integration of musical percepts over time influences listener enjoyment and the level of agreement between the enjoyment ratings of each listener. We used a DNN tool to quantify temporal dependencies in 32 music clips and also computed complexity scores for them. Subjects listened to each music clip while using a rotating dial to provide a continuous enjoyment rating, changing the dial’s position at the …


A Hot Topic:
Congressional Polarization And Climate Change, Mercedes R.P. Wilby Jun 2026

A Hot Topic:
Congressional Polarization And Climate Change, Mercedes R.P. Wilby

Dissertations, Theses, and Capstone Projects

Scholars offer competing explanations for how congressional polarization develops and operates. The literature variously points to shifting agendas, procedural change, or member adaptation or replacement. In this project, I study how congressional polarization occurs by asking what mechanisms account for the emergence of climate policy polarization. Climate policy is a useful test case to evaluate these competing theories. As a relatively low-salience, highly technical issue that is neither new nor inherently ideological, it is not an obvious candidate for deep partisan division. Yet climate policy has become sharply polarized, extending partisan disagreement even to the underlying science.

In order to …


Implicit Attitudes Toward Hearing Aid Visibility: Conspicuous Versus Inconspicuous Hearing Aid Colors, Orly R. Ames Jun 2026

Implicit Attitudes Toward Hearing Aid Visibility: Conspicuous Versus Inconspicuous Hearing Aid Colors, Orly R. Ames

Dissertations, Theses, and Capstone Projects

Hearing aid stigma remains a significant barrier to treatment uptake, with device visibility frequently identified as a contributing factor. Although prior research has examined visibility in relation to hearing aid size and style, the role of color as a distinct aesthetic dimension has not been systematically investigated. The present study assessed whether hearing aid color affects implicit and explicit attitudes toward hearing aids and whether such evaluations differ across contexts. Twenty-six adults who were not current hearing aid users participated in an online quantitative multi-method study consisting of an Implicit Association Test (IAT) and self-report questionnaires. The IAT measured implicit …


Measuring Islamic Republic Propaganda In Western Media Coverage Of Iran: A Computational Framework, Leila Habibi Jun 2026

Measuring Islamic Republic Propaganda In Western Media Coverage Of Iran: A Computational Framework, Leila Habibi

Dissertations, Theses, and Capstone Projects

Detecting propaganda is fundamentally difficult: effective propaganda must simultaneously conceal persuasive intent while achieving persuasive effect, which means that sophisticated propagandistic discourse necessarily occupies the ambiguous middle of a rhetorical spectrum rather than its obvious extremes. This thesis defines this property as the dual constraint problem and argues that it poses two challenges for the binary classification framing that dominates propaganda detection in Natural Language Processing (NLP). First, propaganda by definition does not come with clear labels: no propaganda arm willingly accepts the designation, so reliable ground truth does not exist at the source. Second, because the producer is actively …


Gramsci’S ‘Democratic Philosopher’ And The Concept’S Foundations In Marxian Social Ontology, Eli Recht-Appel Jun 2026

Gramsci’S ‘Democratic Philosopher’ And The Concept’S Foundations In Marxian Social Ontology, Eli Recht-Appel

Dissertations, Theses, and Capstone Projects

This thesis deals with the term ‘democratic philosopher’ from Antonio Gramsci’s Prison Notebooks. In order to lay the groundwork for my distinct interpretation of the ‘democratic philosopher,’ I begin by providing an overview of Gramsci’s theory of the role of intellectuals in civil and political society. I then argue that the ‘democratic philosopher’ emerges from Gramsci’s typology of intellectuals but is a category which is both temporally and ontologically distinct from his more well-known concept of ‘organic intellectuals.’ ‘Organic intellectuals,’ intellectuals who co-develop alongside their fundamental social group or class, occupy a variety of cultural and political roles in …


Counterinsurgency In Afghanistan: Doctrine, Implementation, Cannibalization, Noah S. Fischer Jun 2026

Counterinsurgency In Afghanistan: Doctrine, Implementation, Cannibalization, Noah S. Fischer

Dissertations, Theses, and Capstone Projects

The Taliban return to power in Afghanistan on August 15th, 2021, is a watershed moment in the 21st century history of the United States of America. The swift collapse of the U.S. backed Afghan government shocked American politicians, military leadership, and the general public. To many, trillions of dollars were wasted in funding a government that could not even survive a month without U.S. troops. But those dollars were used by U.S. military leadership to implement a new and innovative strategy those same leaders thought would guarantee success: counterinsurgency, abbreviated as COIN. In this thesis, I will ask: what …


Algorithmic Problems In Automorphic Orbits Of Free Groups, Siobhan B. O'Connor Jun 2026

Algorithmic Problems In Automorphic Orbits Of Free Groups, Siobhan B. O'Connor

Dissertations, Theses, and Capstone Projects

One of the fundamental problems in the field of combinatorial group theory is telling when two group presentations represent isomorphic groups. Since applying a free group automorphism to the set of relators of a presentation gives an isomorphic group, we want to be able to quickly decide when looking at a relator whether a given word can be sent to it via an automorphism. We give a hands-on introduction to the automorphisms of free groups using patterns of colored beads. We show that you can make this decision correctly in constant time on average by looking for "orbit-blocking" words that …


G&P2p: A Multi-Source Approach To Grapheme To Phoneme Conversion, Chun-Yi Peng Jun 2026

G&P2p: A Multi-Source Approach To Grapheme To Phoneme Conversion, Chun-Yi Peng

Dissertations, Theses, and Capstone Projects

This thesis introduces G&P2P, a multi-source framework for grapheme-to-phoneme (G2P) conversion that integrates side pronunciations from multiple lexical resources. Unlike traditional single-source approaches, G&P2P fuses data from multi-sourced pronunciation dictionaries—including CELEX, PronLex, NETTalk, and WikiPron—through several fusion strategies. The goal is to improve model performance on out-of-vocabulary words through multi-source learning. Experiments were conducted with attentive LSTM, pointer-generator LSTM, and pointer-generator Transformer architectures. Models were trained on combinations of datasets and evaluated using word error rate (WER) across five random seeds.

Results show that fusing expert-curated dictionaries such as CELEX and PronLex consistently improves accuracy, achieving an 11.81-point absolute error …


An Investigation Of The Impact Of Privacy On Sexual And Reproductive Health Using Reports On The 2010 Earthquake In Haiti, Jillian E. Myers Jun 2026

An Investigation Of The Impact Of Privacy On Sexual And Reproductive Health Using Reports On The 2010 Earthquake In Haiti, Jillian E. Myers

Dissertations, Theses, and Capstone Projects

In 2010, a massive 7.0 magnitude earthquake hit the capital city of Haiti, Port-au-Prince, causing great destruction of infrastructure and the devastating loss of about 316,000 lives and over a million homes. The earthquake destroyed agricultural production and clean water sources, causing severe resource scarcity along with the overcrowding in the relief camps. Following the earthquake, international aid organizations flooded into Haiti in an effort to help provide immediate relief. The relief efforts were unprepared and lacked coordination among each other to efficiently implement the needed aid services. Without strategic planning to ensure all people’s needs are met, women and …


Gremlin Theory: A Film Art Of Joe Dante, Frank Falisi Jun 2026

Gremlin Theory: A Film Art Of Joe Dante, Frank Falisi

Dissertations, Theses, and Capstone Projects

This thesis seeks to establish the work of the filmmaker Joe Dante as a catalyzing and anarchic force let loose inside larger, dumber superstructures: linear narrativity, Hollywood, America, etc. It works to read the genre films he worked on—many of them made as popular entertainment for mainstream movie studios—as moments of actual subversion, allocating status quo (studio system) resources to create a biting-back against American imperial norms in the lingua franca of Marx and the Marx Brothers: gummy leisure-seeking stupidity and Gremlin transformation. This thesis seeks to argue that to understand Dante’s work is to understand pop transfiguration itself. This …


Mapping Nucleosome Stability: Linking Oncogenic Structural Alterations To Long-Range Allosteric Communication, Augustine C. Onyema Jun 2026

Mapping Nucleosome Stability: Linking Oncogenic Structural Alterations To Long-Range Allosteric Communication, Augustine C. Onyema

Dissertations, Theses, and Capstone Projects

The nucleosome core particle (NCP) is essential for chromatin structure and function, serving as the fundamental unit of eukaryotic chromatin. Oncogenic mutations in core histones disrupt chromatin dynamics, altering DNA repair and transcription processes. How DNA communicates with histones, and how this information propagates through the histone, has been suggested to be a cooperative process. Here, I investigate the molecular consequences of two mutations, H2BE76K and H4R92T, using 36 µs of all-atom molecular dynamics simulations on Anton2. I also characterize the kinetic correlation within histone/DNA domains via conditional activity (CONDACT) using the dihedral angle as our degrees of …


Kanak-Ish Misfits: Queer Imaginaries, Racialized Borders, And The Politics Of Care In Berlin, Germany, Faruk Seref Jun 2026

Kanak-Ish Misfits: Queer Imaginaries, Racialized Borders, And The Politics Of Care In Berlin, Germany, Faruk Seref

Dissertations, Theses, and Capstone Projects

This dissertation examines queer Muslim experiences of border politics, racialization, and care in Berlin, Germany. By formulating bordering as a domineering and oppressive practice of boundary-making, I study how global bordering mechanisms shape and disrupt structures of care, caring, and being cared for. With an intersectional focus on race, gender, sexuality, and sex, I argue that borders are simultaneously materialized and challenged in varying localities, including the nightclub, the queer scene, the diasporic neighborhoods, and households. Ultimately, viewing collective care as fundamental to survival, healing, resistance, and building non-punitive lifeworlds, I theorize the counter-hegemonic practices of queers of color through …


The Evolution Of U.S. Geoeconomic Grand Strategy Toward China And South Korea’S Strategic Space: A Comparative Analysis Of Neomercantilist Types In The Trump And Biden Administrations, Hyungbo Kim Jun 2026

The Evolution Of U.S. Geoeconomic Grand Strategy Toward China And South Korea’S Strategic Space: A Comparative Analysis Of Neomercantilist Types In The Trump And Biden Administrations, Hyungbo Kim

Dissertations, Theses, and Capstone Projects

This study examines the evolutionary trajectory of U.S. geoeconomic grand strategy toward China from the inauguration of the first Trump administration in 2017, through the Biden administration, to the second Trump administration launched in 2025, while exploring South Korea’s survival strategies in response. The findings confirm that U.S. foreign economic policy has radicalized into "Expanded Malevolent Neomercantilism," which moves beyond simple protectionism to weaponize global economic networks in the name of national security and exploit even allies.

According to the analysis, the U.S. progressed from the "Malevolent Neomercantilism" of Trump's first term, which focused on trade deficits, to the "Developmental …

A Data Analysis Study Of Temperature Based On California Cooperative Oceanic Fisheries Investigations (Calcofi) Data., Afsana Mimi

Dissertations, Theses, and Capstone Projects

This research presents an integrated analytical framework for predicting ocean temperatures using long-term observations from the California Cooperative Oceanic Fisheries Investigations (CalCOFI) data files. The study applies advanced data engineering and statistical modeling to assess how a variety of indicators, such as salinity, dissolved oxygen, key nutrients, and ocean depth shape oceanic temperature patterns along the California coastline. Using Microsoft SQL Server software for large-scale data integration and the R for statistical packages (R Core Team, 2025) for statistical computation, I developed and compared multiple regression models, including the ridge regression model, to evaluate the relative influence of physical and …


Considering Numerical Relativity For Upgrades In Mcfacts Merger Dynamics, Shawn K. Ray Jun 2026

Considering Numerical Relativity For Upgrades In Mcfacts Merger Dynamics, Shawn K. Ray

Dissertations, Theses, and Capstone Projects

Binary black hole mergers (BBH), some likely originating from active galactic nuclei (AGN), are observed by ground-based detectors such as LIGO-Virgo-KAGRA (LVK) and will be detected by future space-based detectors such as the Laser Interferometer Space Antenna (LISA) and the Laser Interferometer Lunar Antenna (LILA). The dynamics of AGN may be responsible for a significant fraction of BBH mergers soon to be observed by LISA and LILA, yet the dynamics of BBH mergers within AGN disks remains ambiguous despite their appearance in gravitational wave observations. Monte carlo For AGN Channel Testing and Simulation (McFACTS) is an open-source software used to …


Immunomodulatory And Signaling Molecules From Plant-Associated Bacteria: Toll-Like Receptor 4 Agonist Adjuvants And Diketopiperazine-Mediated Communication, Marian Romaine Jun 2026

Immunomodulatory And Signaling Molecules From Plant-Associated Bacteria: Toll-Like Receptor 4 Agonist Adjuvants And Diketopiperazine-Mediated Communication, Marian Romaine

Dissertations, Theses, and Capstone Projects

Medicinal plants and their associated microbiomes constitute a rich source of bioactive natural products with applications in immunotherapy and microbial ecology. Herbal formulations have long been valued for safe immune enhancement, while bacterial signaling molecules govern community behaviors critical to pathogenesis, symbiosis, and environmental processes. Bacterial lipopolysaccharides (LPS) from plant-associated Gram-negative bacteria have emerged as potent TLR4 agonists, yet their endotoxic potential limits direct use, and diketopiperazines (DKPs) serve as versatile quorum-sensing mediators capable of modulating biofilms in mixed microbial systems.

The work in this thesis comprises two independent but complementary research strands. The first strand pursued the engineering of …


Inductive Biases In Field-Level Cosmological Inference From Galaxy Catalogs, James O'Connor Baldwin Jun 2026

Inductive Biases In Field-Level Cosmological Inference From Galaxy Catalogs, James O'Connor Baldwin

Dissertations, Theses, and Capstone Projects

We perform field-level likelihood-free inference of the matter density parameter Ωm from simulated galaxy catalogs using machine learning models with differing inductive biases. Using features extracted from hydrodynamic simulations in the CAMELS suite, we investigate how both observable choice and model architecture govern the extraction of cosmological information. We consider galaxy positions and line-of-sight peculiar velocities, both separately and in combination, and compare permutation-invariant Deep Sets, implemented with either standard multilayer perceptrons (MLPs) or Kolmogorov–Arnold Networks (KANs), to graph neural networks (GNNs) implemented with MLPs, which explicitly encode spatial relations. We evaluate inference performance under both in-distribution and out-of-distribution (OOD) …
