An Integrated Multivariate Econometric Modeling Framework For Risky Driving Behavior Related Crashes: Evaluating Crash Risk And Severity Across Zones, Pabitra Kumar Roy

Dissertations and Theses

Rapid advancements in crash modeling have yet to fully integrate multiple behavior-driven crash types and their severity outcomes within a single, scalable framework, specially in a way that captures the sequential nature of these behaviors where one risky action may amplify another. This study proposed an integrated multivariate econometric framework to jointly model crash frequency and severity outcomes for three major behaviorally driven crash types: alcohol-related, distraction-related, and aggressive-driving-related crashes. Specifically, using Oregon's 2022 census block group-level crash data, we propose an Integrated Multivariate Negative Binomial – Generalized Ordered Probit Fractional Split (IMNB–GOPFS) model to analyze these dimensions simultaneously while …

Development Of Self-Assembled Polymeric Polyplexes For Microrna Delivery: Toward Treatment Of Alcohol-Associated Liver Disease, Marjina Akter Kalpana

Theses & Dissertations

Self-assembled polymeric polyplexes have the potential to serve as an RNA interference (RNAi) delivery platform for the combined inhibition of CXCR4 and miR-155 in the treatment of alcohol-associated liver disease (AALD). A central challenge in RNA delivery is balancing the extracellular stability of polyplexes, cellular uptake, and intracellular release of RNA cargo. We developed polymeric polyplexes using the CXCR4-antagonist polymer PAMD, designed to target CXCR4 on activated hepatic stellate cells (HSCs) and deliver therapeutic miRNA to activated Kupffer cells (KCs) in fibrotic liver. We improved the polyplexes by cholesterol modification of PAMD and by PEGylation of PAMD-Ch. The cholesterol modification …

Mechanistic Insight Of Neuropilin-2 Expression During The Progression Of Prostate Cancer, Sanika Bodas

Theses & Dissertations

Advanced prostate cancer represents a particularly aggressive and challenging form of prostate cancer (PCa) that shows resistance to both traditional therapies, such as androgen deprivation therapy, and newer treatment modalities like hormone therapies and immunotherapies. For patients diagnosed with advanced stages of PCa, treatment options are limited, and chemotherapy is often the last line of defense. Unfortunately, chemotherapy can severely diminish the quality of life, particularly in older patients, due to its harsh side effects, including fatigue, immune suppression, and overall physical decline. Despite these challenges, researchers and clinicians remain focused on developing more effective and targeted treatments for patients …

Posterior Anatomic Limit For Mandibular Molar Distalization In Subjects With Different Growth Patterns, Genders, And Growth Status, Rehana Bashir

Theses & Dissertations

The objective of this study is to identify the anatomical limits for mandibular molar distalization, a technique frequently employed in orthodontics to address various malocclusions. Mandibular molar distalization plays a critical role in the management of crowding, and correction of the molar relationship.

It is imperative to assess the posterior anatomical space (PAS) in the mandibular retromolar area prior to distalization or uprighting the mandibular molars to avoid periodontal issues (dehiscence, orthodontically induced root resorption, and tooth mobility) and achieve successful treatment outcomes.

A clinical question that, however, isn't well understood is whether the amount of mandibular molar distalization is …

A Comparison Of Tenecteplase To Alteplase For Treatment Of Acute Ischemic Stroke Using Epic Cosmos Database, Marco Gonzalez Castellon

Theses & Dissertations

Ischemic stroke is highly prevalent and an important cause of morbidity, mortality, and long-term disability in the in the United States. The incidence and prevalence of stroke is expected to increase in the next few years due to several factors including aging of the U. S. population, improved treatment, and socioeconomic factors. In 1996, the FDA approved rtPA for the treatment of ischemic stroke patients. Patients had a greater likelihood of recovering successfully. However, rtPA has significant limitations, such as an elevated risk of intracranial hemorrhage, administration difficulties, and limited effectiveness. In March 2025, the FDA approved the use of …

Evaluating Bmx-001 As A Selective Radioprotector For Healthy Tissue In Pelvic Cancers, Molly Myers

Theses & Dissertations

Pelvic cancers, including rectal, anal, and prostate cancer, are relatively survivable cancers with high five-year survival rates, partially due to the addition of radiation to treatment regimens. Radiation confers excellent tumor control, but also causes damage to surrounding tissue, resulting in both short-term and long-term side effects. In a patient population that is surviving longer after treatment, limiting the impact of side effects is instrumental to improving patient quality of life. Radiation-induced ROS is instrumental in causing these side effects and provides a unique opportunity to protect healthy tissue from damage while sensitizing cancer tissue to treatment, as cancer cells …

Development And Characterization Of Non-Viral Delivery Systems For Pulmonary Delivery Of Nucleic Acid Therapeutics, Kasturi Siddhanta

Theses & Dissertations

The development of non-viral delivery systems for pulmonary delivery of nucleic acid therapeutics is driven by the need for safer and more accessible approaches to treat lung diseases, while avoiding the systemic side effects and immune responses associated with viral vectors. Such systems encompass both non-invasive inhalation-based platforms, and systemically administered platforms designed to achieve localized lung delivery. These strategies aim to enable high drug concentrations at the site of action, rapid onset of therapeutic effect, and greater therapeutic efficacy than existing treatments. Designing effective pulmonary delivery systems requires precise optimization of particle properties—including size, morphology, surface characteristics, cell-specific targeting, …

Role Of Nadph Oxidase 4 In Murine Cancer-Associated Fibroblast, Faith M. Gomez

Theses & Dissertations

Breast cancer is the second leading cause of cancer deaths in women in the United States. Frontline hormone therapies for breast cancer prove ineffective in triple negative breast cancer tumors wherein the hormones estrogen, progesterone, and HER2 are downregulated or absent; therefore, patients diagnosed with triple negative breast cancer are primarily limited to chemotherapies which carry a higher failure and resistance rate. Here we target cancer associated fibroblasts as potential drivers of chemoresistance in triple negative breast cancer. We investigated the mechanism by which Nox4 regulates the YAP/TAZ pathway in modulating DTX sensitivity and sought to determine if targeting Nox4 …

Optimal Sizing Of Battery Energy Storage Systems For Peak Shaving And Demand Response Using A Degradation-Aware Bayesian Optimization-Mixed-Integer Linear Programming Framework, Jiwei Yao, Blake Billings, Tao Gao, John Hedengren, Kody M. Powell

Faculty Publications

The increasing integration of renewable energy and rising electricity demand highlight the importance of battery energy storage systems for peak shaving and demand response. Unlike prior approaches that overlook operational impacts on degradation, this study proposes a Bayesian Optimization–Mixed Integer Linear Programming framework for optimal battery energy storage system sizing. In this framework, Mixed Integer Linear Programming determines short-term scheduling while a calibrated electrochemical model iteratively evaluates degradation. The central hypothesis is that the framework can efficiently identify optimal sizes that yield realistic and economically robust outcomes. The method is tested across three scenarios: peak shaving, peak shaving with energy-reduction …

Leveraging Transcranial Ultrasound Stimulation To Enhance Self-Regulation In Emotion And Sleep, Suraya Dunsford, Mica Komarnyckyj, Elsa Fouragnan

School of Psychology

This Perspective article discusses the emerging potential of transcranial ultrasound stimulation (TUS) as a non-invasive neuromodulatory technique for enhancing self-regulatory processes, particularly emotion and sleep regulation, in healthy individuals. Offering high spatial precision and the ability to target both cortical and deep brain regions, TUS uses focused ultrasound waves to induce acute and delayed effects on brain activity. We propose that combining TUS with neurofeedback methods and/or specific cognitive training exercises may capitalise on these neuroplastic effects, thereby augmenting and prolonging their impact to support lasting improvements in self-regulation. We focus on the domains of sleep and emotion regulation, where …
