Math Information Retrieval From Images Via Formula Extraction, Vector Embedding, And Multimodal Llm-Based Question Answering, Angel Wheelwright Crawford

Theses and Dissertations

Math Information Retrieval (MIR) aims to revolutionize the retrieval of math information by addressing the challenges in representing, retrieving, and producing highly specialized math content. In order to develop a robust MIR system, designers must be able to process math equations (MEs) to a format that different systems can use, which is difficult due to various formats math information are stored in, including visual images and document texts. To improve the usage of math information in varied forms for people who are learning and utilizing math, we propose three different methods of handling ME data. The first method is a …

Objectives

Movement behaviors, such as sedentary behavior (SB), light intensity physical activity (LPA), and moderate to vigorous intensity physical activity (MVPA) are mutually exclusive, in that time spent in one behavior inevitably displaces time spent in another. Yet, few studies have simultaneously considered these health behaviors and their association with health-related quality of life (HRQoL), an important indicator of health and well-being in aging populations. This study aimed to explore the role of waking movement behaviors (i.e., SB, LPA, MVPA) in prospectively predicting HRQoL in older adults. The study further aimed to cross-validate associations between movement behaviors and HRQoL using …

Leveraging natural language processing (NLP) techniques and machine learning algorithms—including supervised classifiers and deep learning models such as BERT and LSTM—the framework identifies deceptive content with high precision and low latency. …

New Paradigms In E. Coli Hemolysin Function And Pathogenesis, Hunter Winston Kuhn

Arts & Sciences Graduate Student Theses and Dissertations

Bacterial pore-forming toxins are potent secreted protein effectors that disrupt cellular ion homeostasis by integrating into the plasma membrane. Among them, the RTX toxin alphahemolysin (HlyA) from uropathogenic Escherichia coli (UPEC) has been extensively studied for its hemolytic activity, broad cell tropism, and role in virulence. HlyA was identified as the first type 1 secreted substrate, with β2 integrin CD18/LFA-1 proposed as its receptor. However, its diverse mechanisms of cellular toxicity and impact on outcomes of urinary tract infection (UTI) have remained incompletely defined. During pyelonephritis, renal epithelial cells are at the front line of infection, directly contacting ascending UPEC …

The Influence Of Myocardin Effector Genes On The Tgf-Beta Smad3 Signaling Pathway In Human Pleural Mesothelial Cells, Hema Chandra Hrushi Dusharla

Biotechnology Theses

Pleural Fibrosis (PF) involves excessive extracellular matrix (ECM) deposition, mainly by myofibroblasts, leading to pleural thickening and impaired lung function. Pleural mesothelial cells (PMCs) contribute via mesothelial and mesenchymal transition (MesoMT), triggered by cytokines like TGF-β. Our lab identified Myocardin (MyoCD), a transcriptional co-activator of cardiac and smooth muscle, is a master regulator of pleural fibrosis through interactions with serum response factor (SRF) and Smad2/3 transcription factors which initiate fibrosis signaling. RNA sequencing and qPCR analysis revealed that silencing MyoCD decreased the expression of CTNNB1, MDFI, and Tspan2. MDFI emerged as a potent candidate, as this gene affecting the expression …

Discourse Analysis Of Partner-Focus In Intimate Partner Violence, Maureen Theresa Lowell

Dissertations and Theses

Intimate partner violence (IPV) involves behaviors that harm or threaten to harm an intimate partner; but more importantly, it involves the production of power and control in an intimate relationship that threatens a partner's liberty and wellbeing. As a wicked problem, IPV is challenging to unpack without reducing the complexities that give it its power. This study seeks to explore the complex nature of how abusive men's focus on their partner functions as a mechanism of abuse. To develop the concept of other-focus I draw on constructs of coercive control, power, and dominance. To investigate partner-focus, I conducted a discourse …

Unearthing Evidence For St. Augustine’S Racial Blackness And Paralleling Augustine’S Christian Mystical Religion To Traditional African Religion’S Mysticism, Dillon Cook

Say Something Theological: The Student Journal of Theological Studies

This article undertakes two projects rendering significant ramifications for philosophy/theology, if my assertions are correct. First, the philosopher/theologian known as St. Augustine of Hippo is most saliently recognized as a “white man”; if not a white man, “a European”; if not European, “a man of Rome”; or “Mediterranean”; etc. Outside the intellectual sphere, this is how he is often depicted in art, Penguin Classic books, and so on. Yet ironically, images of Augustine rarely circulate, if at all, as a Black-African-Indigenous person. Was Augustine nonwhite? Evidence is rendered that this is indubitably the case. Could Augustine have been modernly categorized …

Effects Of Oxygen Manipulation On Myofibroblast Phenotypic Transformation In Patients With Radiation-Induced Fibrosis, Eric Mastrolonardo, Sarah Sussman, Bo Yun, Victor Jegede, Dev Amin, Joel Rosenbloom, Andrew P. South, Voichita Bar-Ad, Peter J Wermuth, Adam J. Luginbuhl

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

We tested if hyperoxic conditions can reduce the proportion of active myofibroblasts, which are assumed to be a major driver of head and neck radiation-induced fibrosis, as measured by expression levels of pro-fibrotic genes. Radiated, non-cancerous soft tissue from the head and neck and skin/soft tissue from non-radiated flap donor site were collected from each patient. Myofibroblast density was quantified using immunofluorescence staining with α-SMA and DAPI and visualisation under confocal microscopy and compared between baseline non-radiated and radiated tissue from the same patient. From each tissue specimen, fibroblast cell lines were cultured and exposed to either normoxic, hypoxic, or …

IS is a rare but critical condition that presents significant diagnostic challenges and often leads to poor visual outcomes. It accounts for approximately 5%-10% of scleritis cases and warrants significant attention due to its delayed diagnosis. Ocular surgery is the primary contributor to IS, accounting for a substantial proportion of cases ranging from 58% to 83%, followed by trauma contributing to approximately 10% of cases. IS can be caused by various microorganisms, including bacteria (86%-87%), fungi (11%-13%), viruses, …

Modeling The Influence Of Silicon Content On Electrochemical Performance Of Silicon-Graphite Blended Electrodes Considering Voltage Hysteresis, Mohamed Atwair, Paul T. Coman, Ralph E. White

Faculty Publications

Silicon, with its high specific capacity, is a highly promising material for lithium-ion battery anodes. To enhance durability, it is commonly combined with graphite in composite anodes. Despite this, the electrochemical dynamics between silicon and graphite are not yet fully understood. Modeling serves as an important tool for analyzing and improving batteries, but current models lack comprehensive representation of the coupled electrochemical and structural behavior of silicon-graphite blended electrodes. Herein, we present a comprehensive model for blended Si/Gr electrodes that incorporates the distinct properties and kinetics of each material. Our approach accounts for the dependence of electrode thickness and solid …

Story Forge: A Card-Based Framework For Ai-Assisted Interactive Storytelling, Yaojiong Yu, Gianni Corino, Mike Phillips

School of Art, Design and Architecture

The application of artificial intelligence has significantly advanced interactive storytelling. However, current research has predominantly concentrated on the content generation capabilities of AI, primarily following a one-way ‘input-direct generation’ model. This has led to limited practicality in AI story writing, mainly due to the absence of investigations into user-driven creative processes. Consequently, users often perceive AI-generated suggestions as unhelpful and unsatisfactory. This study introduces a novel creative tool named Story Forge, which incorporates a card-based interactive narrative approach. By utilizing interactive story element cards, the tool facilitates the integration of narrative components with artificial intelligence-generated content to establish an interactive …

The Microtubule-Severing Enzyme Spastin Regulates Spindle Dynamics To Promote Chromosome Segregation In Trypanosoma Brucei, Thiago Souza Onofre, Qing Zhou, Ziyin Li

Faculty, Staff and Student Publications

Microtubule-severing enzymes play essential roles in diverse cellular processes, including mitosis and cytokinesis, by modulating microtubule dynamics. In the early branching Trypanosoma brucei, microtubule-severing enzymes are involved in cytokinesis and flagellum length control, but none of them have been found to regulate mitosis. Here we report the characterization of the microtubule-severing enzyme spastin in the procyclic form of T. brucei. We demonstrate that spastin severs microtubule in vitro and overexpression of spastin disrupts spindle microtubules in vivo in trypanosomes, leading to defective chromosome segregation. Knockdown of spastin impairs spindle integrity and disrupts chromosome alignment and segregation. We further show that …

Using The Safety Scissors: Dna Resection Regulation At Dna Double-Strand Breaks And Telomeres, Michael M, Soniat, Logan R. Myler

Department of Biochemistry and Molecular Biology Faculty Papers

DNA resection is a universal process in genome maintenance by which one strand of DNA is degraded, leaving the other strand intact. This sometimes highly processive process is critical for many forms of DNA damage repair, replication-coupled repair, meiotic recombination, and telomere maintenance. Therefore, resection must be tightly regulated to prevent genome instability and promote faithful and accurate repair. Here, we review what is known about how resection functions and how it is controlled, using DNA double-strand break repair and telomere maintenance as examples. We address how resection is regulated in three independent steps: resection initiation, long-range processing, and termination. …

Improving Door-In-Door-Out Times For Stemi Transfer Patients: Impact Of A Protocolized Autolaunch Process, Hashim Zaidi, Waleed Kayani, Eric Power, Hei Kit Chan, Sini Eapen, Benjamin Karfunkle

Faculty, Staff and Students Publications

Background: The timely transfer of patients with ST-segment elevation myocardial infarction (STEMI) to percutaneous coronary intervention-capable centers is critical for improving outcomes. Although the American Heart Association recommends a door-in-door-out (DIDO) time of ≤30 minutes, national compliance remains low.

Project rationale: At Harris Health, no patients with STEMI met this benchmark before 2022. We implemented a quality improvement (QI) initiative, including an "Autolaunch" process, to expedite STEMI transfers.

Project summary: During 2022-2023, we introduced QI initiatives, including the Autolaunch protocol, for patients with unequivocal STEMI. This process included rapid emergency medical services activation, direct catheterization laboratory transfer, and prearrival cardiologist …
