Impact Of Urban Fine Particulate Matter Exposure On Cardiovascular Health, Shelby P. Briggs

Honors Theses

Air pollution, particularly exposure to fine particulate matter (PM2.5), poses a growing threat to cardiopulmonary health. PM2.5 consists of microscopic particles smaller than 2.5 microns in diameter and originates from industrial combustion, transportation, and urban dust. These particles are classified as xenobiotics and are capable of bypassing respiratory defenses to enter systemic circulation, where they cause oxidative stress, inflammation, and cardiovascular dysfunction. This study examines the effects of PM2.5 on cardiovascular function using a murine model. Male C57BL/6 mice were divided into control (saline), subchronic (10 µg), and chronic (100 µg) groups and were exposed weekly for 11 weeks via …

Background Skeletal muscle atrophy during cancer-induced cachexia remains a significant challenge in cancer management. Mitochondrial defects precede muscle mass and functional losses in models of cancer cachexia (CC). We hypothesized targeting Opa1-a key regulator of mitochondrial fusion-can attenuate LLC-induced CC outcomes.

Methods We utilized 1) in vivo transgenic Opa1 overexpression (OPA1 TG) in LLC-induced CC in vivo, and 2) BPG15 administration to induce Opa1 in vitro and in vivo.

Results OPA1 TG attenuated plantaris, gastrocnemius, and EDL loss with LLC in males and alleviated gastrocnemius loss infemales. OPA1 TG had greater mitochondrial respiration in plantaris and white gastrocnemius, and lowered …

Is Social Media Use A Reason For Socially Withdrawn Individuals' Mental Health Difficulties?, Angela Grundvig

Theses and Dissertations

Studies have found a link between subtypes of social withdrawal and internalizing problems throughout most of the lifespan. However, the work conducted in adolescence is much more limited including a lack of work examining factors that might mediate the association between forms of social withdrawal and internalizing problems. Social comparison may be one way in which social withdrawal predicts internalizing problems. There has been research showing that social media usage is associated with internalizing problems. The purpose of this study was to assess (a) the associations between three subtypes of social withdrawal (shyness, avoidance, and unsociability), respectively, and indices of …

A Novel High-Order Absorbing Boundary Condition For Elastic Multiple Scattering Problems, Jordan Gregory Sheppard

Theses and Dissertations

Elastic waves are waves that propagate by causing deformations in an elastic medium such as metal, rock, or rubber. The main characteristic of elastic wave motion is the coexistence of multiple types of waves at once in the medium, including compressional and shear wave components. This type of motion can be used to study the impacts of physical phenomena such as earthquakes. In this paper, we discuss our research on the time-harmonic scattering of elastic waves in a medium by multiple circular cylindrical obstacles that the wave cannot penetrate. Using the Helmholtz decomposition, we break down the vector-valued physical system …

High Temperature In Potato: Plant Responses And Adaptive Cultivation Strategies To Increase Production, Siska Rahmayani Gultom, Jajang Sauman Hamdani, Kusumiyati

Jurnal Kultivasi

Climate change, with global temperatures rising by 1.09°C from 1850–1900 to 2011–2020, threatens potato production, a critical staple crop, by exceeding the optimal temperature range of 15–20°C. This review synthesizes over 45 peer-reviewed studies published between 2015 and 2025 from Google Scholar and ScienceDirect to evaluate the physiological, morphological, and tuber quality responses of potatoes to high temperatures and to identify adaptive cultivation strategies for sustainable production. High temperatures reduce photosynthetic efficiency through chlorophyll degradation and stomatal closure, increase respiration, and divert photosynthates to vegetative growth, leading to 18–32% yield losses globally by the 2050s. Heat-tolerant varieties, such as Atlantic …

Versatile Waveform Generation And Clocking Techniques For Rfsoc-Based Digital Designs, Michael David Jones

Theses and Dissertations

Within an ever-evolving radio-frequency (RF) environment, designers are required to adapt systems to increasingly constricted parameters. The available tools continually grow to match this need, but so does the complexity in using them. The radio-frequency system-on-chip (RFSoC) is an innovation that combines a field-programmable gate array (FPGA) with an integrated RF chain. Designing with an RFSoC allows for high-precision data transmission, sampling, and processing, but it can be difficult and time-consuming to develop specialized circuits. The open-source CASPER project aims to provide a library of abstracted block-design components to simplify the design process. An arbitrary waveform generator (AWG) is created …

Coolness, Leisure, And Power : The Development Of Mokanshan Summer Resort In Modern China, 1890–1937, Xuyan Pan

Lingnan Theses (MPhil & PhD)

The concept of "coolness" (清涼) embodied fundamentally different bodily and cultural experiences in Chinese and Western traditions. With the introduction of Western-style summer resorts by foreign missionaries in the 1890s, these divergent understandings converged and clashed in new spatial forms. This study examines Mokanshan (莫干山), located in Zhejiang province and recognized as one of the Republican era’s “Four Great Summer Retreats” (民國四大避暑地), as a paradigmatic case of transnational leisure. Initially developed by missionaries as a health-oriented retreat, a transnationally managed enclave, and a nostalgic “overseas home” for expatriates, Mokanshan reflected a hybrid model of modern leisure shaped by foreign institutions. …

Between Shelter & Ash: A Design Policy Atlas For Wildfire-Resiliency, Daisy Elizabeth Morales-Zaragoza

McNair Summer Research Program

Architectural design holds a powerful potential in the face of wildfire threats, yet remains underutilized in fire resilience strategies. This study will explore how design, at the level of the house, street, and community, can move beyond code compliance toward holistic protection. Through analysis of principal fire codes such as IWUIC, CBC Chapter 7A, and NFPA 1144, visual diagrams, precedent case studies, and original architecture proposals, the paper proposes a multiscale design framework that expands our understanding of resilience. It argues that while fire codes establish critical baselines, spatial planning, form, and materials must work in concert with social and …

Lifestyle-related health problems remain a leading cause of chronic illness in the United States, creating a need for more effective communication of health information. However, the mechanisms that influence how individuals understand and use health information are not yet fully understood. This exploratory study investigates the intersections of statistical health literacy, emotions, and health decision-making from an interdisciplinary perspective. Guided by prior literature suggesting potential relationships among these factors, the study hypothesized that statistical literacy and emotional responses would modify responses to the form of health information presentation, affect the believability and motivational impact of the information, and influence health …

Modeling Dynamic And Static Earthquake-Induced Stress Changes Across Fault And Magmatic Systems: Insights From Finite Element Simulations, Luis Ivan Bazan Flores

Electronic Theses and Dissertations Archive

Earthquakes generate stress perturbations capable of influencing adjacent faults and magmatic systems across a range of spatial and temporal scales. This work investigates how dynamic and static earthquake-induced stress changes affect geological structures in two different tectonic settings: major continental fault systems and subduction zones. The first part of this study examines dynamic rupture interactions between the southern San Andreas Fault and an adjacent normal fault beneath the Salton Sea. Our results indicate that dynamic rupture simulations informed by high-resolution seismic reflection profiles of the normal fault help us uncover the direction of rupture propagation of past events on the …

All In God's Plan?: Examining Positive And Negative Religious Coping As Moderators Of Posttraumatic Stress And Alcohol Use Following Intimate Partner Violence Exposure, Mya Elizabeth Bowen

Electronic Theses and Dissertations Archive

Intimate partner violence (IPV) is defined as physical violence, sexual violence, stalking, or psychological aggression by a current or former intimate partner or spouse (The Centers for Disease Control and Prevention, 2020). Recognized as a pervasive public health concern, approximately 41% of women report experiences of sexual violence, physical violence, and/or stalking, and over 61 million women report experiencing psychological aggression, all at the hands of an intimate partner (Leemis et al., 2022). The pervasive nature of IPV is particularly concerning as experiences of violence can result in significant negative physical and psychological health concerns, including the development of PTSD …

Investigating Techniques To Optimise The Layout Of Turbines In A Windfarm Using A Quantum Computer, James Hancock, Matthew Craven, Craig Mcneile, Davide Vadacchino

School of Engineering, Computing and Mathematics

This paper investigates Windfarm Layout Optimization (WFLO), where we formulate turbine placement considering wake effects as a Quadratic Unconstrained Binary Optimization (QUBO) problem. Wind energy plays a critical role in the transition toward sustainable power systems, but the optimal placement of turbines remains a challenging combinatorial problem due to complex wake interactions. With recent advances in quantum computing, there is growing interest in exploring whether hybrid quantum-classical methods can provide advantages for such computationally intensive tasks. We investigate solving the resulting QUBO problem using the Variational Quantum Eigensolver (VQE) implemented on Qiskit’s quantum computer simulator, employing a quantum noise-free, gate-based …

Faculty Research, Scholarly, and Creative Activity

Residential childcare workers provide critical support to vulnerable children around the world. Building and maintaining a qualified residential childcare workforce is challenged by myriad forces, the foremost of which is recruiting and retaining staff for valuable work often misaligned with available compensation; making individual qualifications at hiring; ongoing training; supervision; and data support systems to monitor performance critical for quality care. This study explored the similarities and differences among these essential elements of staffing across distinct programs: Youth Education Centers (YEC) in Poland, CiudadEscuela Muchachos (CEMU) in Spain, and the Boys Town Family Home Program (BTFHP) in the United States. …

Cognitive Reserve In The Deaf/Hard Of Hearing Community: An Exploration Of Contributing Factors, Olivia B. Allaby

Theses

Cognitive reserve (CR) refers to the individual differences in how people execute tasks, allowing some to cope with cognitive challenges more effectively than others. Additionally, previous studies have established a link between age-related hearing loss and cognitive decline. However, CR and cognitive aging have not been explored extensively in those who might identify as Deaf/hard of hearing (HH). There are four features potentially unique to this community that could shape one’s CR: use of hearing technology (e.g., hearing aid), bimodal bilingualism, and social connectedness and social support. One hundred fifty-nine Deaf/hard of hearing participants completed an online survey study assessing …

Children’s Nutrition Research Center Staff Publications

PI3K inhibition causes apoptosis selectively in NOTCH1-mutant head and neck squamous cell carcinoma (HNSCC), but modest single-agent responses and acquired resistance (AR) limit the clinical efficacy of targeted agents. To address these limitations, we investigated novel combination therapies. We tested the efficacy of 5768 compounds as single agents and 139 in combination with PI3K inhibitors in sensitive and AR NOTCH1-mutant HNSCC cell lines. We generated synergy/efficacy classifications for the combinations using multiple metrics of statistical drug synergy and growth rate indices. The PLK1/PI3K combination's efficacy was validated using orthogonal in vitro methods and in two HNSCC xenograft models. Compound efficacy …

Developing Resilience In First Year Collegiate Athletes: The Effectiveness Of A Resilience And Strengths Based Course, Dorian J. Hayden

Dissertations, 2020-current

Research shows that college students have increased levels of mental health difficulties with freshmen transitioning into college experiencing even more strain. What further contributes to these difficulties includes having experienced the COVID pandemic in high school, low socioeconomic status (SES), and racial minority status. Student-athletes, although known to have better mental health than non-student-athletes, still underutilize their abundance of resources. Generally, a skill that has been established as beneficial in managing the difficulties related to college is resilience, suggesting the implementation of a more accessible resource to support the mental health of student-athletes transitioning into college. One such resource is …
