Disparities Between Reported And Actual Study Habits And Perceptions Among First Year Occupational Therapy Graduate Students, Melisa P. Kaye, Marcella Mccollum, Sydney Hanzalik

Journal of Occupational Therapy Education

Studying for exams forms a significant part of the occupational therapy graduate school experience. While successful completion of exams is a central focus for students, little time is devoted to explicitly teaching new graduate students how to most effectively study. Instead, when they enter their occupational therapy programs, students experience a steep learning curve, and often rely on previous habits or trial and error to discover the most efficacious study strategies. The purpose of this study was to examine the study behaviors, habits, and beliefs of new graduate students to gain insight into the prevalence of use of various study …

Faculty, Staff and Students Publications

Introduction: Anomalous aortic origin of a coronary artery (AAOCA) is associated with sudden cardiac death. The intramural (IM) length is considered high-risk, yet radiologic measurements by computed tomography angiography (CTA) show variable agreement with measurements at surgery. We aimed to develop a semi-automatic computational method to estimate IM length in a retrospective cohort of surgical AAOCA patients.

Methods: In 58 patients [49 right(R), 9 left(L)], CTA images were used to generate 3D segmentations of the aorta and a centerline of the anomalous coronary. The distance from the centerline to the aortic segmentation was calculated. The IM length was estimated from …

A New Interpolated Pseudodifferential Preconditioner For The Helmholtz Equation In Heterogeneous Media, Sebastian Acosta, Tahsin Khajah, Benjamin Palacios

Faculty, Staff and Students Publications

This paper introduces a new pseudodifferential preconditioner for the Helmholtz equation in variable media with absorption. The pseudodifferential operator is associated with the multiplicative inverse to the symbol of the Helmholtz operator. This approach is well suited for the intermediate and high-frequency regimes. The main novel idea for the fast evaluation of the preconditioner is to interpolate its symbol, not as a function of the (high-dimensional) phase-space variables, but as a function of the wave speed itself. Since the wave speed is a real-valued function, this approach allows us to interpolate in a univariate setting even when the original problem …

Psychophysiological Tools & Techniques To Predict Perceptual Motor Task Outcomes, Bobby Gerald Rawls Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

The process of perceiving environmental information, analyzing it, formulating a plan of action, and carrying out said plan is vital to our day to day lives. This loop occurs for every motor task we perform, from actions as simple as elbow flexion to as complex as performing surgery. As such, it is imperative to understand what physiological, psychological, and neurocognitive factors most dictate success or failure in the motor performance loop.

Prior research has shown that measures from each of these facets have strong relationships with motor performance outcomes, though these findings tended to rely on artificially produced stress in …

Rational Design Of Small Molecules Targeting Mitochondrial Redox Proteins, Matheus Barbosa Belchior

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reactive oxygen species play a crucial role in many cellular processes. Despite being a natural byproduct of cellular metabolism, overexpression of these species causes damage to the cell, leading to cell dysfunction. Central to the regulation of these highly reactive molecule is the mitochondria. Impairment in its function has been associated with oxidative stress within the cell. Herein, a ligand-based and structure-based approach to design new small molecules to inhibit mitochondrial redox proteins associated with oxidative stress and reactive oxygen species. In the first project two molecules were synthesized and characterized as potential monoamine oxidase B inhibitors. Results showed two …

Computational Approaches For Diagnosing Neurological Impairments And Restoring Functional Movement, Serhii Bahdasariants

Graduate Theses, Dissertations, and Problem Reports (ETD)

Movement is the primary means by which the nervous system converts intention into interaction with the environment. Voluntary limb motion enables standing, walking, reaching, and grasping—actions that underpin self‑care, communication, and economic participation. When diseases or injuries disrupt the pathways that couple neural commands to muscle forces—whether through cortical stroke, spinal cord injury, or peripheral nerve damage—mechanical outcomes such as weakness, loss of coordination, and ultimately reduced mobility emerge. These impairments cascade into secondary complications, increased dependence on caregivers, and diminished quality of life. Quantifying how the lesion alters the mechanics of movement is therefore essential for designing targeted interventions …

Towards the first goal, the history of the method of least squares, state statistics, and positive and negative eugenics are outlined, followed by a close reading of the foundational texts authored by Francis Galton and Karl Pearson that introduced linear regression. Towards the latter goal, English-language statistics textbooks published between …

Biomechanics Of The Atherosclerotic Lipidome: (Un)Expected Statin Interactions And Membrane Remodelling, Ethan M. Fong

Pomona Senior Theses

Statins interact with lipid membranes in ways that shape their pharmacokinetics, off-target effects, and pleiotropic actions, yet these interactions' mechanical and biophysical consequences remain poorly understood. This thesis employs a combination of surface plasmon resonance (SPR), quartz crystal microbalance with dissipation monitoring (QCM-D), and rheological modelling to characterize how representative statins intercalate within biomimetic supported lipid bilayers (SLBs) of healthy and diseased composition. SPR reveals that lipophilic statins exhibit higher apparent affinities and slower dissociation kinetics, especially in cholesterol- and anionic lipid-rich membranes. QCM-D analyses demonstrate that statins alter membrane mass, dissipation, and interfacial stiffness in a statin- and membrane-dependent …

Dissecting The Biophysical Mechanisms Of Oleate Hydratase Association With Membranes, William A. Lathram, Robert J. Neff, Ashley N. Zalla, James D. Brien, Vivekanandan Subramanian, Christopher D. Radka

Markey Cancer Center Faculty Publications

This study investigates the dynamics of oleate hydratase (OhyA), a bacterial flavoenzyme from Staphylococcus aureus, and its interactions with lipid membranes, focusing on the factors influencing membrane binding and oligomerization. OhyA catalyzes the hydration of unsaturated fatty acids, playing a key role in bacterial pathogenesis by neutralizing host antimicrobial fatty acids. OhyA binds the membrane bilayer to access membrane-embedded substrates for catalysis, and structural studies have revealed that OhyA forms oligomers on membrane surfaces, stabilized by both protein-protein and protein-lipid interactions. Using fluorescence correlation spectroscopy (FCS), we examined the effects of membrane curvature and lipid availability on OhyA binding to …

The model captures shifts in transmission following policy changes and quantifies the reduction in deaths attributable …

Automated Treatment Planning Framework For Cervical Cancer In Brachytherapy, Suman Gautam

Theses and Dissertations

Brachytherapy (BT) is a critical treatment modality for cervical cancer that delivers ionizing radiation directly to the tumor using intracavitary (IC) and/or interstitial (IS) applicators. In high dose-rate (HDR) BT, a remote afterloader guides the radioactive source to specific dwell positions for defined durations, known as dwell times, allowing for a conformal dose to the tumor while minimizing exposure to surrounding organs at risk (OAR). However, due to the inherent nature of ionizing radiation, some dose to OARs is unavoidable, creating a fundamentally conflicting objective in treatment planning: maximizing tumor coverage while minimizing OAR dose. This characterizes the problem as …

Synthesis Of Tu100 Analogs And Biological Assays, Feyisope Tonye Oladapo

College of Graduate Studies: Theses & Dissertations

TU100 (14-methyl-5H-5,12-epiminobenzo[4,5]cyclohepta[1,2-b]naphthalene-6,11,13(12H)-trione) exhibits exceptional chemotherapeutic properties. It operates via a distinct mechanism that triggers cell death to create cytotoxic effects while concurrently inhibiting topoisomerase I and II. Its efficacy rivals that of well-known chemotherapeutic drugs like Daunorubicin. The distinctive characteristics of TU100 have led to initiatives aimed at creating structurally similar compounds to discover even more effective bioactive alternatives.

The analog synthesis incorporated quinoxaline or its derivatives (diphenyl quinoxaline, dipyridinyl quinoxaline, and dibenzophenazine-10,13-dione) that have been shown to have promising chemotherapeutic effects. Synthesizing the hetero naphthoquinones required a multi-step synthetic process, so quinoxaline/ derivatives intermediates are first prepared, then the …

Hafnium Oxide-Based Nanoheterostructures For Catalytic Radiosensitization And Enhanced X-Ray Radiotherapy, Marlen Dariela Calix Quezada

Theses and Dissertations

Orthovoltage X-ray beams are attractive for surface and intra-operative radiotherapy. Yet, their clinical utility is constrained by rapid attenuation and the limited dose that can be delivered without harming healthy tissue. High-Z hafnium oxide (HfO₂) nanoparticles can boost local energy deposition through the photoelectric effect, while catalytic surface defects accelerate water radiolysis. Harnessing both mechanisms in a single nano-heterostructure could enable potent radiosensitization at diagnostic-range energies.

This thesis develops and evaluates HfO₂-based nanoheterostructures, both bare and Au-decorated, as catalytic radiosensitizers.

Two types of HfO₂ were evaluated, one was synthesized following a specific route and the …

Explorations Of Dna-Single-Walled Carbon Nanotube Interactions To Develop Multiplexed Molecularly Specific Biosensors For Inflammation, Amelia K. Ryan

Dissertations and Theses

Inflammatory cytokines such as interleukin-6 (IL-6) and interleukin-12 (IL-12) are central regulators of immune signaling and key biomarkers of disease, yet existing assays for their detection remain slow, invasive, and lack multiplexing ability. This dissertation advances the development of single-walled carbon nanotube (SWCNT) optical nanosensors capable of real-time, multiplexed, and molecularly specific cytokine detection through innovative use of single-stranded DNA (ssDNA) interfaces.

First, an IL-6-specific DNA aptamer was employed as both a dispersing agent and recognition probe for SWCNT fluorescence sensing. Sequence modifications, including anchor domains, truncations, and thermally induced refolding, were systematically tested to optimize sensitivity and selectivity. The …

Swift: Strong-Signal Weighted Prs Integration For Fine-Tuning, Yikai Dong

Public Health Theses

Polygenic risk scores (PRS) hold immense promise for personalized medicine but suffer from reduced accuracy in non-European populations, hindering equitable application. We introduce SWIFT (Strong-signal Weighted PRS Integration for Fine-Tuning), a novel framework to enhance cross-population PRS prediction by optimally combining base scores from diverse ancestries using only GWAS summary statistics. SWIFT employs a GWAS subsampling technique based on data fission to generate internal training and tuning sets, circumventing the need for external validation cohorts. A key innovation is its focus on strong genetic signals (p < 0.1) for estimating robust combination weights via cross-validation, which mitigates overfitting and significantly reduces computational burden. We evaluated SWIFT across 22 complex traits using data from five populations (EUR, AFR, AMR, EAS, SAS) and independent validation cohorts (UK Biobank, All of Us). Applied to state-of-the art base methods (PRS-CSx, X-Wing, JointPRS), SWIFT achieved predictive accuracy comparable or superior to the recent LEOPARD integration method and baseline implementations. Crucially, SWIFT demonstrated a 3.5- to 9.5-fold reduction in computational runtime compared to LEOPARD and exhibited robust performance even when using a single, unified LD reference panel. SWIFT provides an efficient, robust, and practical approach to improve the accuracy and applicability of PRS across diverse populations, representing a significant step towards more equitable genomic medicine.

Effectiveness Of Wolbachia Introgression On Dengue Incidence In A Complex Urban Environment, Karthika Satyanarayanan

Dengue is an arboviral disease of increasing global public health importance for which more than half the world’s population is at risk. The burden of dengue has increased greatly in the last decade; in 2024, over 14 million cases and 10,000 dengue-related deaths were reported, marking a historical milestone. The endosymbiotic bacterium Wolbachia (wMel strain) offers a promising alternative to traditional control methods through its reduction of Aedes aegypti vector competence and introgression into wild Ae. aegypti populations. This thesis evaluated the dynamics of Wolbachia introgression and its effect on reducing dengue incidence up to 31 months after the completion …

Temporal Analysis In Connectivity Structure Of Human Disease Co-Occurance Network, Jingxuan Xu

Public Health Theses

Recent research on human disease networks (HDNs) has revealed the importance of jointly analyzing multiple diseasesand their interconnections, yet many existing approaches focus on molecular-based data and do not fully capture non-molecular relationships. Building on the concept of the phenotypical HDN, we leverage Medicare inpatient claims data to construct a comprehensive disease co-occurrence network. In our framework, two diseases are deemed interconnected if their observed probability of co-occurrence significantly deviates from that expected under independence. We adopt the weighted gene co-expression network analysis (WGCNA) framework to build our network, using a ϕ-correlation measure and a hard threshold to ensure a …

Establishing A Conventional Linac-Based Electron Flash Beam, Justin Defrancisco

Theses and Dissertations

Problems: A rediscovered radiotherapy technique, FLASH, involves increasing the dose rate to >40 Gy/s. For a given dose, FLASH is shown to decrease the normal tissue complication probability without affecting the tumor control probability. More preclinical studies are necessary to confirm and enable these desirable properties on humans. Current preclinical investigations have diverse constraints, requiring FLASH apparatuses with flexible parameters and accurate control. However, there are limited FLASH platforms available, the existing ones are costly. Our institution is not in possession of any such infrastructure. Even if available, dosimetry and beam control in FLASH are extremely lacking. There is …
