Reconnection-Driven Electron Acceleration, Ripudaman Singh Nirwan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Magnetic reconnection converts the magnetic energy available in a plasma to the kinetic energy of its constituent particles. In the simplest case, it occurs between anti-parallel magnetic field lines meeting in a plane. Another variant known as ‘component reconnection’ involves field lines reconnecting at an angle, giving a non-zero magnetic field component perpendicular to the plane of reconnection. This component is known as the ‘guide field’ and it is normalized to the reconnecting field in the literature. The guide field controls the particle-scale dynamics of reconnection and influences the ensuing particle acceleration.

Component reconnection occurs in the Earth’s magnetosphere, along …

Neurobiological Variables Mediating the Relationship between

Breast Cancer and Sleep Disruption

Brittany D. Elliott, MS

Breast cancer is the most commonly diagnosed malignancy in women, with more than two million new cases diagnosed world-wide each year. Improvements in screening technology and diagnostics have increased survival rates, but cancer-associated sleep disruptions persist for the majority of breast cancer survivors well beyond the treatment period. In addition to reducing quality of life, reduced sleep quality is associated with greater incidences of affective dysfunction, reduced treatment efficiency, aggressive cancer progression, increased symptom severity, and increased mortality by all causes. Thus, identifying the variables …

Deep Target Recognition: Semi-Supervised Annotation, Sensor Fusion And Super-Resolution, Shoaib Meraj Sami

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the recent expansion of machine learning algorithms to cover a wide range of disciplines, several areas of automatic target recognition (ATR) remain underexplored. This dissertation presents tools developed to improve performance in three significant aspects of ATR: semi-supervised annotation, sensor fusion, and image super-resolution. The aim of the semi-supervised methods is to automatically annotate targets in scenarios where labeled data are scarce in the target domain but available in the source domain. Secondly, to address the limitations of individual image sensors and enhance robustness under different environmental conditions and man-made constraints, a sensor fusion algorithm was developed to improve …

Replicating The Functionality Of Ghost Knifefish Cerebellar Feedback Using Synthetic Nervous Systems, Sheldon Paul Cj Johnson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sensory inputs allow animals to perceive, react, and adapt to an environment. However, the sensory information received by the body, such as visual, auditory, and proprioceptive information, could become overwhelming, thus overloading the brain. Yet, animals can process all this information by canceling redundant signals from their surroundings, allowing them to be more sensitive to novel or unexpected signals in their environment. Each species (i.e., birds, fish, mammals) has its own way of using and filtering sensory information, from auditory to locomotion adaptivity. Cerebellar circuits contribute to sensory filtering in a variety of systems. In particular, research on Ghost knifefish …

Bridging The Gap Between Structural And Cellular Biology: Insight Into The Organization Of Glycolytic Enzymes In Cells, Heather Hansen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Glycolytic enzymes are spatially organized in the cytoplasm, and are shown to localize with cellular structures such as the plasma membrane, F-actin, mitochondria, or associate independently within the cytosol. The assembly of these enzymes is hypothesized to regulate pathway flux to meet the energetic needs of the cell. However, it is unclear whether all of these assemblies have the same mechanism of formation or function in the cell. We investigated the role of glycolytic enzyme assemblies in cells, using the glycolytic “gatekeeper” enzyme phosphofructokinase-1 (PFK1). PFK1 is extensively regulated by multiple mechanisms, including over 20 allosteric ligands, post translational modifications, …

Survival And Spatial Ecology Of North American River Otters (Lontra Canadensis) In West Virginia, Laurel Marie Glover

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wildlife reintroductions function to regain wildlife populations in areas where they have been extirpated or greatly diminished. One such species that has been reintroduced to several states is the North American river otter (Lontra canadensis). The West Virginia Division of Natural Resources (WVDNR) conducted a river otter reintroduction effort between 1984-1997, releasing 245 individuals into the state. The reintroduction was deemed a success with the WVDNR opening a regulated trapping season for river otters in 2011, allowing trappers to take one river otter per season. As the population has reestablished in West Virginia, several management challenges have arisen …

Probing The 10-23 Dnazyme Catalytic Core: Insights From Structural And Mechanistic Studies, Evan Rhyse Cramer

Graduate Theses, Dissertations, and Problem Reports (ETD)

The 10-23 DNAzyme is a catalytically active DNA oligonucleotide capable of cleaving RNA at purine-pyrimidine junctions in the presence of divalent metal ions, most notably magnesium. Despite its promise as a programmable RNA knockdown tool, its clinical and biotechnical utility has been hampered by limited structural characterization, low catalytic efficiency under physiological conditions, and poor understanding of its in-cell activity. This dissertation presents a comprehensive framework for the structural and functional analysis of DNAzymes using the 10-23 DNAzyme as a model system. In the absence of high-resolution structures, we first employed detailed in vitro biochemical assays to map essential residues …

The fifth generation (5G) of mobile networks introduced groundbreaking improvements in connectivity, latency, and reliability. As 5G continues to expand across commercial and de- fense sectors, ensuring the privacy and integrity of its authentication mechanisms remains paramount. The foundation of 5G security lies in the Authentication and Key Agreement (AKA) protocol, which enhances user identity protection and establishes mutual authenti- cation between the user equipment (UE) and the network. Despite these advances, several weaknesses persist, including replay-based desynchronization, linkability, and correlation at- tacks under realistic adversary models. This thesis provides a unified analysis of these vulnerabilities and introduces a lightweight …

Characterizing Nursery Habitat For Juvenile Invasive Carp (Hypophthalmichthys Spp.) On The Ohio River, Rebecca Hiller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since their introduction to US waters, Silver Carp (Hypophthalmichthys molitrix) and Bighead Carp (H. nobilis) have rapidly spread throughout the Mississippi River basin and its major tributaries, but their invasion has stalled within the Ohio River. Recent research has suggested this slowed spread could be due to a lack of suitable nursery habitat in the Ohio River, affecting recruitment of invasive carp. This study aims to characterize the habitats juvenile carp are utilizing by investigating three main lines of inquiry: that juvenile carp habitat use is limited by (1) the flow regime of the Ohio River …

Effects Of Environmental And Anthropogenic Gradients On Fish Beta Diversity In Central Appalachian Streams, Alanna Kaylee Lowther Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding the environmental and spatial drivers of community composition is essential for conserving freshwater biodiversity. We examined how environmental gradients, land cover, and spatial structure influence fish beta diversity in wadeable streams across West Virginia, USA. We quantified total beta diversity and partitioned it into species replacement and richness difference components and used local contributions to beta diversity (LCBD) to identify compositionally unique sites. Community–environment relationships were evaluated with distance-based redundancy analysis (dbRDA), and a beta regression GLMM was used to test how elevation, slope, land cover, and stream order (factor) predicted LCBD while accounting for spatial structure (dbMEMs) and …

Membrane Reactor Modeling And Optimization For Hydrogen Production, Ayooluwa Tomiwa Akintola

Graduate Theses, Dissertations, and Problem Reports (ETD)

There has been an ongoing trend toward cleaner fuels for more environmentally benign forms of energy generation. Recently, hydrogen has been identified as a clean fuel for energy generation. However, the most established, efficient, and widely utilized technique for producing hydrogen remains the steam methane reforming (SMR) in the presence of catalyst. Unlike other fossil fuels, utilizing methane from natural gas in an SMR process to produce hydrogen emits less, but yet a notable sum of carbon dioxide. Furthermore, the endothermic nature of SMR reactions imply that there is a high energy requirement to obtain a substantial amount of hydrogen …

The Abuse Liability Of Oral Nicotine Pouches In Electronic Cigarette Users, Jakob D. Bohland

Graduate Theses, Dissertations, and Problem Reports (ETD)

Oral nicotine pouches (ONPs) are products containing synthetic or tobacco derived nicotine in a cellulose pouch. While relatively novel in their current state, ONPs are increasing in popularity, with little known about their national level prevalence. Extant work has suggested that electronic cigarette (e-cig) users may be interested in ONPs; however, no abuse liability studies have been conducted comparing ONPs directly to e-cigs. In the few abuse liability studies that have been conducted, ONPs have been evaluated in comparison to combustible cigarettes or smokeless tobacco (SLT). These studies suggest ONPs may be less reinforcing than combustible cigarettes or SLT. Therefore, …

Extending Effects Of The Good Behavior Game With Mixed Schedules, Amina Boukhris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Student disruptive behavior in the classroom can adversely affect both students and teachers. The Good Behavior Game (GBG) is a well-established classroom management strategy used to reduce disruption. However, its use remains limited due to implementation barriers reported by teachers, such as effort associated with delivering feedback, and the limited generalization of the GBG effects to times when the game is not in place. The current study had two main objectives: (a) to evaluate whether a modified version of the GBG implemented on a mixed-schedule-like arrangement (MIX GBG) could reduce student disruption as effectively as the standard version (MULT GBG), …

Implementation Of The Novel Nurse Intuition Patient Deterioration Scale To Assess For A Correlation Among Nurse Intuition And Patients Returning To The Intensive Care Unit, Janie L. Walsh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction/Background: Adult hospitalized medical and surgical patients at an academic medical center are being transferred out of the Intensive Care Unit (ICU) to the step-down floor and having rapid response calls in less than 48 hours after the transfer. Nurse intuition is not a consideration in the decision to transfer a patient. Physiological variables such as Modified Early Warning Scores (MEWS) and vital signs are relied on heavily as indicators for escalation or de-escalation of care. There is evidence supporting the use of acknowledging nurse intuition to better predict a patient’s readiness for transitions of care.

Purpose: To evaluate the …

Adolescent Attachment And Anxiety: Examining Implicit Emotion Beliefs And Emotion Regulation As Mediators, Jeanette Pool

Graduate Theses, Dissertations, and Problem Reports (ETD)

Anxiety is a growing issue in adolescents, with teens reporting worse and more severe symptoms in recent years (Kajastus et al., 2023; Solmi et al., 2022). There are several risk factors for developing anxiety symptoms, including cognitive, behavioral, and social factors. Effective emotion regulation (ER) has been shown to be helpful in decreasing anxiety symptom levels (Arbulu et al., 2023; Cho et al., 2019). A better understanding of precursors of ER could aid in prevention of anxiety. ER may stem from our personal beliefs about emotions (Ford et al., 2018; Schroder et al., 2015; Tamir et al., 2007) and to …
