Characterizing And Manipulating Intra-Die Performance Variation Of Fpgas And Its Application In Security, Hayden C. Cook

Theses and Dissertations

Field Programmable Gate Arrays (FPGAs) are reconfigurable, high-performing devices that are often used in critical applications. However, like all semiconductors, FPGAs experience transistor aging that can lower performance and lead to device failures. Additionally, device aging also has several security implications. Therefore, understanding the aging mechanisms behind transistor aging is necessary to ensure the reliability of FPGAs. However, current aging studies either rely on simulation alone or are unable to isolate aging effects on specific elements within the FPGA. This dissertation uses the reconfigurability of FPGAs to develop novel aging techniques that allow for the targeted aging of specific areas …

Facets Of Neuroticism As Predictors Of Heart Rate Variability And Psychological Distress, Mikel Cressman

Theses and Dissertations

Heart rate variability (HRV) and personality are related to both physical and mental health outcomes. Previous research has found a relationship between neuroticism and distress while the findings on the relationship between neuroticism and HRV are mixed. Studying the facets of neuroticism may provide a more nuanced view of the effects of personality on HRV and distress. Previous research has suggested that the vulnerability facet of neuroticism appears to be uniquely related to the cardiovascular response to stress. This study's first hypothesis is that individuals with higher scores on the vulnerability facet will have lower heart rate variability. The second …

From Viral Rumors To Fact-Checked Information: The Influence Of Social Media Platforms And Fact-Checking Organizations On Public Trust During The Covid-19 Crisis, Chinyere Linda Agbasiere

Theses and Dissertations

The COVID-19 pandemic not only disseminated a viral health threat worldwide but highlighted the rapid spread of misinformation, commonly called an "infodemic." This study investigates the influence of social media and fact-checking organizations in shaping public trust and information consumption during the pandemic. Utilizing a mixed-method approach of surveys and interviews, I analyzed 9 interviews. The interviews were analyzed using thematic analysis (Braun & Clarke, 2006) and Owen's (1984) principles of recurrence, repetition, and forcefulness, and three main themes were developed inductively. The findings reveal that while social media was a primary source of information, it also served as a …

Drop Dynamics And Heat Transfer During Dropwise Condensation On Superhydrophobic Surfaces, Shaur Humayun

Theses and Dissertations

As we seek to address the escalating demand for energy and water, superhydrophobic surfaces have gained the attention of researchers due to their potential to boost condensation heat transfer rates and improve efficiency across various applications. One way to significantly improve dropwise condensation heat transfer rate is to improve drop mobility. Water-repelling properties of superhydrophobic surfaces can help in reducing the size of condensed drops as they depart the surface, thus increasing drop refresh rates by increasing drop mobility. Accurate models of retention forces between drops and superhydrophobic surfaces are needed for predicting drop dynamics including drop mobility. Once drop …

Investigating The Role Of Betrayal Blindness Between High Betrayal Trauma And Dating Violence Among Young Mothers Maltreated As Children, Lauren Catherine Wallace

Theses and Dissertations

Young mothers experience greater rates of dating violence (DV) victimization and perpetration compared to their non-parenting, female peers as well as older mothers (Joly & Connolly, 2016). Child maltreatment is a salient predictor of DV victimization and perpetration (Li et al., 2019; Murphy et al., 2020). According to Betrayal Trauma Theory (BTT), child maltreatment perpetrated by a close loved one, such as a parent or primary caregiver, is defined as a high betrayal trauma (Freyd, 1996). Young mothers who experienced a high betrayal trauma may endorse betrayal blindness as a way to cope with abuse from their caregiver (Freyd & …

I also use the Google Search API and content analysis to suggest that blended, digital, and flexible may be post-secondary institutions' most frequently used terminology to describe contexts incorporating online and in-person components. I also gather qualitative data from interviews with faculty to highlight the context and nuances surrounding blended teaching competencies, including creative innovation, technology …

Rigorous Verification Of Stability Of Ideal Gas Layers, Damian Anderson

Theses and Dissertations

In this thesis we develop tools for carrying out computer assisted proof of the stability of traveling wave solutions of the spatially one-dimensional compressible Navier-Stokes equations with an ideal gas equation of state. In particular, we obtain rigorous, tight error bounds on a high-accuracy numerical approximation of the traveling wave profile for parameters corresponding to air, and we obtain rigorous representations in a neighborhood of positive and negative infinity of the solution to the first order ODE associated with linearizing the PDE equations about the traveling wave solution. We also develop supporting tools for rigorous verification of wave stability.

Saved By Naloxone: The Path To Sobriety?, Marli Rose-Firillo Fichtner

Theses and Dissertations

Beginning in the early 2000s, lawmakers sought to mitigate harm and reduce mortality rates by enacting various policies and increasing community outreach, such as educating society about the dangers of opioids. These efforts can be divided into two broad categories: Drug use prevention and harm reduction. Research has been conducted on both of these strategies, utilizing retrospective analysis on outcomes including crime and mortality, among others. It is of great interest to understand which policies are most effective. NALs are an example of harm reduction because they reverse overdoses should they occur. Preemptive naloxone distribution reduces the likelihood of fatal …

Interleukin 24 Induces Apoptosis Through Glycogen Synthase Kinase-3 Beta Inactivation In Prostate Cancer Cells, Sual J. Lopez, Moira Sauane

Theses and Dissertations

Interleukin 24 (IL-24) is a tumor-suppressing protein currently in clinical trials. IL-24 induces cancer-specific apoptosis by activating endoplasmic reticulum (ER) stress and mitochondria dysfunction. We have previously demonstrated that IL-24 leads to apoptosis in cancer cells by protein kinase A (PKA) activation in human breast cancer cells. To further understand the mechanism by which IL-24 induces apoptosis, I analyzed the role of glycogen synthase kinase-3 (GSK3), a highly conserved and normally active serine/threonine kinase in cancer cells and downstream target of PKA. The work reported here provides direct evidence that GSK3 was inhibited following IL-24 treatment in human prostate cancer …

Students Speak: A Qualitative Examination Of The Intersection Of Identity And Sexual Violence In A University Setting, Danika M. Charles

Theses and Dissertations

Sexual violence remains a public health concern in the United States. Much of the research has focused on gender-binary individuals, despite the heightened vulnerability of Black, transgender, and nonbinary (BTN) individuals due to societal stigma and discrimination. Campus climate surveys have been recommended by the Obama Administration to address sexual violence, though they often underrepresent BTN students, failing to capture their unique experiences. This study aims to bridge this gap by focusing on the intersection of gender and racial identities, using an intersectional stigma framework to explore the prevalence and impact of sexual violence on BTN students and advocate for …

Actions Taken At Firm-Level To Mitigate The Adverse Impacts Of Climate Risk, Deepak G. More

Theses and Dissertations

This dissertation comprises of two essays on actions taken at firm-level to mitigate the adverse impacts of climate risk. Our first essay documents a positive relation between firm-level climate change exposure (CCE) and long-term tax avoidance. Our results suggest that firms use tax avoidance to mitigate the adverse impacts of CCE. The positive effect of CCE on tax avoidance is stronger post the release of Stern Review and weaker after the enactment of the Tax Cuts and Jobs Act, 2017. Our study is the first to show that firms with high CCE use tax avoidance to increase cash holdings as …

The Effect Of Advertising On Consumer Self-Improvement Motivation: When And How Advertising Motivates Consumers, Suwakitti Amornpan

Theses and Dissertations

In today's modern world, advertising permeates nearly every facet of consumers’ daily lives, from billboards over city streets to posts seamlessly integrated into social media feeds. The current research identifies a positive unintended consequence of advertising on consumer behavior: increased consumer self-improvement motivation. Across four studies, I find that exposure to mass (vs. luxury) advertising increases consumer motivation to engage in self-improvement. Specifically, I argue that because advertisements for mass (vs. luxury) products prime attainable (vs. unattainable) consumption goals, they increase consumer confidence in their ability to achieve their consumption goals (i.e., they enhance self-efficacy perceptions). This, in turn, puts …

Decisions, Decisions: Dna Damage Induced Modification Of P53 And The Effect Of Modifications On P53 Differential Binding To The Dna, Savannah Gabrielle Keating

Theses and Dissertations

p53 is the most frequently mutated tumor suppressor protein in cancer. It is highly regulated, most often via post-translational modifications (PTMs). Different pathways and target genes are differentially activated by p53 and there is much left to understand how this occurs. The regulation of p53 at the post-translational level is incredibly important to its DNA damage response, and, therefore, it is understood that PTMs are often involved in the differential activation of pathways by p53. This project aimed to identify some of the types and locations of post-translational modifications on p53 in response to different modes of DNA damage with …
