Uniform Stability Of Katyusha In Strongly-Convex Settings, Don Li

University Honors Theses

Acceleration of convergence and reduction of variance constitute a trade-off in the design of stochastic optimization machine learning algorithms. Katyusha was introduced to address this trade-off, synthesizing Nesterov Accelerated Gradient (NAG) and Stochastic Variance-Reduced Gradient (SVRG) into a single first-order optimizer with promising empirical performance. However, the generalization properties of Katyusha remain largely unexplored. We conjecture that, in the smooth quadratic regime (i.e., under assumptions of strong convexity and smoothness of the loss function, and boundedness of gradients), Katyusha is uniformly stable in the sense of Bousquet and Elisseeff. Instantiating our framework for NAG, we extend the use of Lyapunov …

Seeing A Future Where I Exist As Myself: An Exploration Of Suicidality As A Response To Sociopolitical Oppression In Transgender And Gender Expansive Populations, Alexander Ray Sequoia

University Honors Theses

Suicide is often considered a mental health issue alone. For Transgender and gender non-conforming (TGNC) people, suicide can be a response to erasure of self and living under oppression conditions. The sociopolitical climate in the United States (U.S.), has become more hostile for TGNC people, along with legislative action that criminalizes their existence. This project explores the intersections of identity and nuances of suicide and death. The present study consists of 14 semi-structured interviews. This study examined the intersections of gender and culture on suicide responses, highlighting the importance of culturally relevant and community-led support for Transgender and gender expansive …

The Gut Microbiome, The Gut-Brain Axis, And College Student Well-Being, Idi Mckay

University Honors Theses

This literature review examines how diet, stress, environmental exposure, and food accessibility may influence college students' mental health and academic performance through the gut microbiome and the Gut-Brain Axis (GBA). Current microbiome research often focuses on early childhood development, clinical disease populations, or older adults, while overlooking college-age students who experience significant social, environmental, and biological transitions. College students frequently face food insecurity, irregular eating patterns, chronic stress, inconsistent sleep schedules, and reduced access to nutrient-dense foods, all of which may influence microbial diversity and overall gut health.

This thesis explores how modern campus environments and lifestyle factors may contribute …

Media Literacy Education In Hadhramout Governorate, Case Study: Hadhramout University, Amal Omar Ba Qatyan

Theses and Dissertations

Media literacy is an essential skill in today’s digital environment (Khoirunnisa, Udiana, & Zahra, 2025), especially in conflict-affected societies where misinformation and propaganda spread rapidly through social media platforms (Uzochukwu et al., 2025). In Yemen, the ongoing conflict has weakened the education system and reduced access to reliable information, which increases university students’ vulnerability to misleading, biased, and inaccurate media content (Moharram, 2026). Despite the recognized importance of media literacy education, academic research on this topic remains very limited in Yemen, particularly in Hadhramout Governorate.

This study addresses this research gap by examining the current state of media literacy education …

Metal Oxide Nanoparticle‑Integrated Phema Hydrogels: Morphology, Chemical Properties, And Biological Interaction, Venkateswar Rao, Collin Cox, Brandon Clark, Arushi Rai, Erick S. Vasquez-Guardado, Madhuri Kango-Singh, Soubantika Palchoudhury

Chemical and Materials Engineering Faculty Publications

Hydrogels offer attractive matrices for incorporating inorganic metal oxide nanoparticles (NPs) to generate multifunctional hybrid materials, but challenges remain in scalable synthesis and correlating their properties to bio-interaction. Therefore, we report the synthesis and characterization of poly(2-hydroxyethyl methacrylate) (pHEMA) hydrogels, and pHEMA hydrogels encapsulating iron oxide or zinc oxide NPs, using a modified free-radical polymerization. Dose-dependent survivorship studies on Drosophila melanogaster revealed that both NP-embedded hydrogels are tolerated over a wide dose range (e.g., 50–200 mg), although ZnO NP-gels exhibit lower survivorship at some concentrations due to their inherent composition and a wider size distribution of iron oxide NPs.

Person-Centered Profiles Of Body Image (Dis)Satisfaction Among Adolescents And Young Adults With Type 1 Diabetes, Adora Elise Choquette

Electronic Theses and Dissertations Archive

Individuals with type 1 diabetes (T1D) are uniquely vulnerable to body image dissatisfaction due to a complex interplay of pre-existing psychosocial risk factors and health demands necessitated by T1D care. These individual-level risk factors lend to high degrees of heterogeneity in body image (dis)satisfaction. Given that body image dissatisfaction heightens the risk of disordered eating behaviors and subsequent adverse diabetes-related outcomes, it is important to understand antecedents of body image dissatisfaction in individuals with T1D to inform care. The present study included a sample of adolescents and young adults (AYA) ages 13-35 with T1D (N=891, Mage=21.14 years (SDage=6.03 years), 57.8% …

A Parallelized Multi-Component Radiation Testing Methodology For Systems-On-Chip, Weston M. Smith

Theses and Dissertations

As the space industry expands, there is an increased reliance on system on chip (SoC) devices in high radiation environments. The reliability of these devices becomes crucial, especially in space applications. The industry's rapid growth has led to a massive expansion in the use of Commercial Off-The-Shelf (COTS) components. Electronic systems are vulnerable to single event upsets (SEUs) and the failure modes caused by SEUs are not fully understood, especially for COTS SoCs. Standard radiation testing techniques of SEUs use a single core of a multi-core processor to monitor bit flips. In this work, we present a parallelized radiation testing …

Readiness Before Adoption: Exploring Ai Integration In Egyptian Nonprofit Fundraising, Marwa Y. Zayed

Investigating Femoral Growth Stunting And Cortical Bone Deposition: A Bioarchaeological Case Study From 17th Century Transylvania, S. M. August Stone

Electronic Theses and Dissertations 2020 - Present

This study utilizes the World Health Organization’s growth stunting identification standards to investigate the possibility of growth stunting in a collection of subadult remains from Telekfalva, Transylvania, Romania. Length-for-age is estimated using femur length and dental development stage (Shaefer et al., 2009) and compared to the Maresh Standard Growth Data (Maresh, 1943, 1955, 1970). Growth stunting is identified in individuals who fall less than -two standard deviations from the expected femur length-for-age. Additionally, this research investigates a pattern of abnormal, multilayered cortical bone deposition seen primarily in individuals with growth stunting. The correlation between abnormal cortical bone deposition and growth …

Will Beauty Save The Brain? Exploring The Relationship Between Eudaimonic Reels Exposure And Egyptian Gen Z'S Mind And Motivations, Petra Zaky

Theses and Dissertations

Social media entertaining content includes a mixed bag of the meaningful and the trivial. For Generation Z, whose favorite daily entertainment is shallow yet funny short-form videos (reels), there is often an invisible price paid. The loss of ability to watch long meaningful videos, distractedness from self, “Brain Rot”, glamorizing of hedonism are among the maladies left behind the attractive rabbit hole of their daily media diet. This study explores the relationship between exposure to meaningful reels, in contrast to pleasurable reels, and Gen Z’s reflective thinking, “Brain Rot” symptoms, motivation to watch long meaningful videos and life motivations between …

Bap1 Loss Links Myc Activation, Stress Response Vulnerability, And Disease Progression In Kidney Cancer, Ilya Strunilin

Arts & Sciences Graduate Student Theses and Dissertations

BAP1, a chromatin modifier, is a frequently mutated tumor suppressor in clear cell renal cell carcinoma (ccRCC). Mutations in BAP1 are associated with a more aggressive and lethal disease. However, the downstream mediators of BAP1 loss in ccRCC oncogenesis are not well understood. To better understand mechanisms of BAP1-mediated tumor suppression, I have extensively characterized the very early transcriptional mediators of BAP1 loss in a postnatal kidney-specific genetic knockout model. Because VHL loss is the initiating event in ccRCC, we modeled Bap1 loss in a Vhl-deficient background. I have found that Vhl/Bap1 double-knockout cells of PT segment S2 strongly activate …

Women And Wars: Understanding Women’S Political Empowerment Post- Conflict In France, Lebanon, And Sierra Leone, Alaa S. Sayed

Theses and Dissertations

This thesis attempts to discusses how conflict can be a time of change for women and how conflict can be a crucial aspect for change and improvement. Conflict provides a chance for the women to witness and experience the disruption of gender roles, which was a common practice during wartime, as women were placed in roles that were not officially theirs, according to what society adheres to or ascribes as acceptable roles for women. The conflict is presented as a “window” of opportunity. However, the reality of the situation of this “window” is not uniform across all post-conflict societies; the …

Fatherhood In Egypt: Identity Formation And Role Theory Perspectives, Mahmoud Nasr Gawdat

Theses and Dissertations

Fatherhood is a central yet under-researched dimension of family life in Egypt, particularly from a psychological and identity-based perspective. This study explores how Egyptian fathers construct and experience fatherhood through the lenses of identity theory and role theory. Using a qualitative research design, seven focus groups were conducted with 43 Egyptian fathers to examine the meanings they attribute to fatherhood, their perceived roles, challenges, support systems, and personal transformations. Thematic analysis revealed six interconnected themes: (1) describing the father’s role, (2) learning the father role, (3) social and cultural influences on the father role, (4) meaning of being a father, …

Experimental And Numerical Analyses Of Eccentric Bolted Connections Subject To Shear And Torsion, Mohannad Mahran Zanaty

Theses and Dissertations

Steel connections are one of the pillars of the steel structures construction industry, and yet, it still to this day holds some ambiguities in our design procedures. Several authors believe that the elastic-based methods constricted connection design into a conservative approach, and accordingly initiated a method called Instantaneous Center, which is a method indicating that the center of rotation is around a fictitious point. The method was investigated analytically by exploring the domain and found the method often present multiple roots, with one of the roots often indicating an unrealistic point of rotation with a marginally high exaggerated capacity of …

A Novel Design-For-Test Flow Using Librelane, Mohamed E. Gaber

Theses and Dissertations

Design-for-testing is a crucial element of application-specific integrated circuit design, yet, in the nascent open-source electronic design automation scene, the solutions for it are sorely limited. Design-for-test-enabled chips allow defects to be caught early on in the manufacturing process, avoiding incurring huge costs if hardware with defective chips is shipped to equipment manufacturers or, worse, end-users. Yet, the current open-source solutions rely on a brute-force utility that does not scale and negatively impacts the design by holding design-for-testing features as co-equal with the design’s regular operation, and a nominally layout-aware solution that does not holistically integrate into a larger flow. …

Enhancing The Performance Of Brain-Computer Interfaces Via A Spatially-Aware Framework, Ahmed Ayman Eloraby

Theses and Dissertations

Electroencephalography (EEG)-based brain–computer interfaces (BCIs) provide a non-invasive pathway for communication, with the P300 speller being one of the most established paradigms. Despite its practicality, EEG signals present inherent challenges, including low signal-to-noise ratio, high dimensionality, and limited spatial resolution. These characteristics complicate the extraction of discriminative spatial patterns, which are critical for accurate P300 detection and character-level decoding.

This thesis addresses these challenges through the development of AttenPCA-Net, a deep learning framework that integrates spatially-aware processing with dimensionality reduction. Principal Component Analysis (PCA) is employed to reduce redundancy and noise while preserving the most informative components of the EEG …

Theses and Dissertations

The rapid rise of Instagram influencers has transformed the ways young women engage with media, shaping perceptions of appearance, lifestyle, success, and everyday behavior. This study examines how frequent exposure to Instagram influencers affects self-esteem, internalization of beauty and lifestyle ideals, perceived realism of influencer content, and behavioral and consumption habits among young Egyptian females. The study explores participants’ lived experiences, interpretations, and coping strategies in relation to influencer culture. Perceived influencer credibility emerged as a key factor for females to follow them, influencers viewed as relatable, specialized, and transparent were more likely to inspire adaptive behaviors, whereas those promoting …

Creating Public Value Through Public-Private Partnerships In Technical And Vocational Education And Training In Egypt, Aseel Amr Tajuddin

Theses and Dissertations

Technical and Vocational Education and Training (TVET) has emerged in the last decade as a foundational pillar for Egypt’s workforce and economic development vision. More recently, the Egyptian Ministry of Education and Technical Education (MoETE) has scaled industry driven and Public Private Partnerships (PPPs) TVET models, industry affiliated dual education programs and Applied Technology Schools (ATS), seeking to strengthen alignment with the labor market and improving TVET graduates employability. Yet, TVET in Egypt continues to suffer from persistent social stigma, limited social legitimacy and low social ranking, despite the state led reform efforts. Existing TVET literature remains limited to examining …
