INTRODUCTION: To date, most mammography-related AI models have been trained using either film or digital mammogram datasets with little overlap. We investigated whether or not combining film and digital mammography during training will help or hinder modern models designed for use on digital mammograms.

METHODS: To this end, a total of six binary classifiers were trained for comparison. The first three classifiers were trained using images only from Emory Breast Imaging Dataset (EMBED) using ResNet50, ResNet101, and ResNet152 architectures. The next three classifiers were trained using images from EMBED, Curated Breast Imaging Subset of Digital Database for Screening Mammography (CBIS-DDSM), …

The Behavior Of Partially Coherent Twisted Space-Time Beams In Atmospheric Turbulence, Milo W. Hyde Iv

Faculty Publications

We study how atmospheric turbulence affects twisted space-time beams, which are non-stationary random optical fields whose space and time dimensions are coupled with a stochastic twist. Applying the extended Huygens–Fresnel principle, we derive the mutual coherence function of a twisted space-time beam after propagating a distance z through atmospheric turbulence of arbitrary strength. We specialize the result to derive the ensemble-averaged irradiance and discuss how turbulence affects the beam’s spatial size, pulse width, and space-time twist. Lastly, we generate, in simulation, twisted space-time beam field realizations and propagate them through atmospheric phase screens to validate our analysis.

Live-Sky Gnss Signal Processing Using A Dual-Polarized Antenna Array For Multipath Mitigation, Eric Hahn, Sanjeev Gunawardena, Chris Bartone

Faculty Publications

Excerpt: Multipath results from reflections of Global navigation satellite signals (GNSS) signals arriving at a receiver that are delayed with respect to the desired line-of-sight (LOS) signals. The delayed signals distort the received LOS signals, thereby causing pseudorange and carrier phase measurement errors. Traditional multipath mitigation techniques include antenna gain pattern shaping (primarily to reduce ground multipath) and correlator gating techniques (such as narrow correlator and double-delta correlator [1]).

Opening The Virtual Window: How On-Line Processes Could Increase Access To Justice In The Criminal Legal System, Cynthia Alkon, Amy Schmitz

Faculty Scholarship

This article explores the potential of technology to improve access to justice (A2J) in criminal courts, specifically for nonviolent misdemeanor cases. Despite a push for innovation in courts, criminal courts have been slow to embrace change and technological innovation due to factors like constitutional constraints and funding limitations. This article argues that criminal courts need "virtual windows" alongside traditional "brick and mortar doors" to enhance A2J. It proposes a problem-solving approach focusing on misdemeanor cases, a high-volume category where technology can have a significant impact. The paper highlights the importance of ensuring defendants make "knowing and intelligent" pleas despite the …

The Environmental Democracy That Was, Then Wasn't, But Could Be Again, Daniel E. Walters

Faculty Scholarship

Over the 50 years since former EPA Administrator William D. Ruckelshaus wrote The Citizen and the Environmental Regulatory Process, much has changed. On the one hand, participation in environmental regulatory decisionmaking has flourished, but on the other, Ruckelshaus's prediction of growing consensus around the environmental movement has proven illusory. In this short essay reflecting on participation in environmental regulatory decisionmaking, I highlight what Ruckelshaus was right about and, just as importantly, where his vision of environmental participatory governance might need some updating. Looking back at the dawn of environmental democracy in the regulatory process and comparing it to the …

Theses and Dissertations

The advancement of Fifth Generation Network (5G) technology is well underway, with Mobile Network Operators (MNOs) globally commencing the deployment of 5G networks within the mid-frequency spectrum range (3GHz–6GHz). Nevertheless, the escalating demands for data traffic are compelling MNOs to explore the high-frequency spectrum (24GHz–100GHz), which offers significantly larger bandwidth (400MHz-800 MHz) compared to the mid-frequency spectrum (3GHz–6GHz), which typically provides 50MHz-100MHz of bandwidth. However, it is crucial to note that the higher-frequency spectrum imposes substantial challenges due to exceptionally high free space propagation loss, resulting in 5G cell site coverage being limited to several hundred meters, in contrast to …

Risk Assessment And Geographic Impact Of Virtual Power Purchase Agreements And Unbundled Renewable Energy Certificates On Greenhouse Gas Abatement, Keyshon L. Bachus

Theses and Dissertations

Fossil fuel-generated energy consumption via electricity purchased by organizations makes up much of worldwide greenhouse gas (GHG) emissions. Commercial and industrial users consume more than two-thirds of electricity. Companies with warehouses, offices, data centers, and other facilities that engage in industrial processes consume significant amounts of purchased energy to power their operations. Most organizations do not generate electricity or have operational control of their energy generation; instead, they purchase it from public utilities and other providers. Many organizations are making climate commitments to support the Paris Agreement’s Net-Zero pledge by reducing or offsetting their indirect “Scope 2” greenhouse emissions and …

The Effect Of Metacognition On Medical Laboratory Science Students' Perceived Feelings Of Self-Efficacy, Rebecca Simone Bakke

Theses and Dissertations

Medical laboratories across the United States have been experiencing a workforce shortage for the past several decades. While the causes of this shortage are numerous, one of the contributing factors is high turnover and attrition rates due to low workplace satisfaction. Research has shown that higher levels of self-efficacy lead to increased job satisfaction and performance outcomes. Therefore, increasing the self-efficacy of medical laboratory science (MLS) students as they prepare to transition into the workforce may help address the labor shortage.To explore a potential exercise to increase self-efficacy among MLS students, a metacognitive learning strategy—reflective journaling—was implemented during the final …

Synthesis Of A Low-Cost And High-Performance Micro-Spherical Adsorbent For Co2 Capture: Performance Evaluation, Up-Scaling Assessment, Adsorption Kinetic, And Numerical Simulation, Abdelmalek Bellal

Theses and Dissertations

This dissertation explores the potential use of potassium carbonate (K2CO3) supported adsorbents for large-scale carbon dioxide (CO2) capture processes. The post-combustion carbon capture process, which operates independently of the upstream fuel combustion process and the CO2 partial pressure in the flue gas, is emphasized for its integration into conventional coal-fired power plants without extensive modifications. While mature aqueous amine facilities are the industry standard, drawbacks in the predominant monoethanolamine (MEA) technology, such as high energy dissipation and oxidative degradation, motivate the exploration of adsorbent-based processes.Various adsorbents, including K2CO3-supported ones, are considered promising due to their high theoretical CO2 capture capacity …

Preparing Special Educators And Team Members To Support Students With Severe Behaviors In Schools, Tamara Ann Hoffer

Theses and Dissertations

The critical nationwide teacher shortage (Billingsley et al., 2019), puts increasing pressure on educator preparation programs to train candidates in less time. Special education personnel are more likely to leave the field when they feel inadequately prepared for service (Mason-Williams et al., 2020), and are less likely to leave the field when they feel connected with schools that promote inclusion, multi-disciplinary teaming, and collective responsibility for all students (Billingsley et al., 2019). Educators perceive their training inadequate for supporting children who demonstrate disruptive and destructive behaviors in the classroom (Mason-Williams et al., 2020). Despite significant research for evidence-based methods for …

Inhibition Of Mirna Associated With A Disease-Specific Signature And Secreted Via Extracellular Vesicles Of Systemic Lupus Erythematosus Patients Suppresses Target Organ Inflammation In A Humanized Mouse Model, Nicholas A Young, Emily Schwarz, Braden M Zeno, Shane Bruckner, Rosana A Mesa, Kyle Jablonski, Lai-Chu Wu, Elisha D O Roberson, Wael N Jarjour

2020-Current year OA Pubs

INTRODUCTION: Distinct, disease-associated intracellular miRNA (miR) expression profiles have been observed in peripheral blood mononuclear cells (PBMCs) of systemic lupus erythematous (SLE) patients. Additionally, we have identified novel estrogenic responses in PBMCs from SLE patients and demonstrated that estrogen upregulates toll-like receptor (TLR)7 and TLR8 expression. TLR7 and TLR8 bind viral-derived single-stranded RNA to stimulate innate inflammatory responses, but recent studies have shown that miR-21, mir-29a, and miR-29b can also bind and activate these receptors when packaged and secreted in extracellular vesicles (EVs). The objective of this study was to evaluate the association of EV-encapsulated small RNA species in SLE …

Hydrogen Deuterium Exchange And Other Mass Spectrometry-Based Approaches For Epitope Mapping, Prashant N Jethva, Michael L Gross

2020-Current year OA Pubs

Antigen-antibody interactions are a fundamental subset of protein-protein interactions responsible for the "survival of the fittest". Determining the interacting interface of the antigen, called an epitope, and that on the antibody, called a paratope, is crucial to antibody development. Because each antigen presents multiple epitopes (unique footprints), sophisticated approaches are required to determine the target region for a given antibody. Although X-ray crystallography, Cryo-EM, and nuclear magnetic resonance can provide atomic details of an epitope, they are often laborious, poor in throughput, and insensitive. Mass spectrometry-based approaches offer rapid turnaround, intermediate structural resolution, and virtually no size limit for the …

Theses and Dissertations

The present study explored the development and initial validation of a measure of doctoral student self-efficacy for students in Health Profession Training (HPT) programs. There is a gap in existing scales that measure the full spectrum of tasks that contribute to doctoral self-efficacy. The scales that do exist focus on broad self-efficacy (Chen et al., 2001) or program-specific self-efficacy in one area (Stump et al., 2012; Van Horn & Christman, 2017; Lent et al., 2003). Our purpose was to develop and provide initial norming and validity information for the Self-Efficacy of Applied Doctoral Students (SEADS) Scale. The SEADS was developed …

Environmental Toxicity Of Isoxazoline Drugs On Non-Target Species, Haley M. Cooper

Theses and Dissertations

Lyme disease affects tens of thousands of people every year in the United States, causing serious illness and even death. It is caused by the bacterium, Borrelia burgdorferi, through infected black-legged tick bites. The range of these ticks is expanding, causing Lyme disease cases to increase. Considerable effort has been put toward research and eradication of Lyme disease, with limited success. Isoxazoline drugs, commonly used to prevent flea and tick infestations in dogs, could be dispatched in the field to keep black-legged ticks off the reservoir host of Lyme disease, the White-footed mouse. Little research has been done on …

Acaricidal Activity Of The Orally Administered Isoxazoline Drugs (Lotilaner, Fluralaner, And Afoxolaner) In White-Footed Mice Against Larval Ticks, Emily Marie Gisi

Theses and Dissertations

Lyme disease, caused by Borrelia burgdorferi, is currently the most prevalent vector borne disease in North America. With the CDC estimating almost 500,000 new cases every year, methods are needed to control the vector, the black legged tick (Ixodes scapularis). Like other tick-borne diseases, Lyme disease is zoonotic and involves tick parasitism on rodent reservoirs in the wild. The main reservoir host of Lyme disease is the white-footed mouse (Peromyscus leucopus). This study aims to explore the effectiveness of a reservoir targeted control approach by the treatment of white-footed mice with oral isoxazoline class drugs. …

A Measure Predicting Treatment Outcome For Sexual Offenders, Kaitlin Alyssa Guston

Theses and Dissertations

Researchers generally agree that treatment reduces the likelihood of sexual offender recidivism. However, studies show attrition rates of up to 85% in some treatment programs for sex offenders. Because many risk factors for recidivism and treatment attrition are the same, the present study used gold-standard risk assessments to predict which sex offenders would not complete a community treatment program. The Static-99r, Stable-2007, and URICA assessed static risk factors, dynamic needs, and responsivity to treatment for 289 sex offenders. Pre-treatment scores from the sex offenders in the sample indicated that these assessment instruments could predict treatment attrition for sex offenders in …

How Abortion Status Predicts Stigmatizing Beliefs: Measuring Enacted Stigma Using The Stereotype Content Model, Jenna Nichole Laurin

Theses and Dissertations

Enacted stigma consists of active discrimination or negative treatment towards an individual who has received an abortion. Further, stereotypes of individuals typically fit within perceptions of competence and warmth, however these stereotypes have not been measured about women who have received an abortion despite the fact that they can indicate stigmatizing beliefs. Additionally, enacted stigma may present differently between men and women. The purpose of the current study was to measure perceptions of competence and warmth as a form of stigma about women with and without a history of abortion, as well as women who considered an abortion but did …

Core Values In Higher Education: Students, Faculty, Staff, And Administrator Alignment At A Midwestern Research University, Rodney Deshan Lewis

Theses and Dissertations
