Bigeminy With Prolonged Qt Interval As An Ominous Sign For Impending Torsades De Pointes: A Case Report, Thuc K. Vu, Jake Valentine

Student Publications

Introduction: Ventricular ectopic beats and corrected QT interval (QTc) prolongation are both relatively common entities that are typically benign. It is difficult to predict subsequent dysrhythmias from either electrocardiogram (ECG) feature. The combination of both features may better predict the risk of torsades de pointes. We highlight a case of torsades preceded by a bizarre bigeminal rhythm with QTc prolongation likely caused by memantine use and hypokalemia.

Case Report: An 84-year-old female presented to the emergency department with a fall. A syncope workup revealed an ECG demonstrating bigeminy with a prolonged QTc interval. Several minutes after obtaining the ECG, the …

Monsters, Multiplicities, And Liminal Experiences In Doctoral Education: Fabulation As Research Methodology, Anna V. Gonzalez

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation was to experiment with qualitative research methodologies while exploring the complexities of doctoral education, research practices, philosophies of inquiry, and other topics intersecting with(in) educational scholarship. My vision for this work was fueled by postmodernist critiques of humanist education, frustrations with the methodological status quo pervasive in educational research, and deep concerns about the unsustainability of performance-focused teaching and learning.

The logic I follow in this project is simple: if we—researchers and academics—are to contribute solutions for challenges and ongoing crises in our world, then we must start thinking relationally and in ways more complex …

Seasonal And Interannual Abundance, Distribution, And Carbon Production Estimates In The Northeastern Gulf Of Mexico Using The Sipper Camera Imaging System, Carlyn Scott

USF Tampa Graduate Theses and Dissertations

Larvaceans are filter-feeding gelatinous zooplankton whose contributions to marine biogeochemical processes are poorly constrained. By frequently shedding their particle-rich houses and producing dense fecal pellets, larvaceans contribute large amounts of particulate organic matter to deeper waters and to the sea floor. Despite their importance, little is known about larvacean abundance, distribution, and carbon production in the highly productive northeastern Gulf of Mexico (NEGOM). To address this gap in knowledge, we collected images of larvaceans at discrete depths in the upper 300 m of the water column between August 2010 –2014 using the Shadowed Image Particle Profiling and Evaluation Recorder (SIPPER) …

First, the extent to which the revealed asset allocation matched the elicited asset allocation was examined. Next, the portfolios were examined relative to diversification within the stock and bond holdings. Portfolios were examined on the basis of hypothetical historical risk and return. Lastly, comments provided by financial professionals about their security selections and investment approach were presented. …

Analysis Of The Impact Of Pavement Characteristics On Road Traffic Safety And Pavement Management Using Statistical Heterogeneity Models, Huiqing Lyu

USF Tampa Graduate Theses and Dissertations

Pavement shall accommodate current and predicted traffic needs in a safe, durable, and cost-effective manner. Among pavement surface characteristics, pavement friction is a critical factor contributing to roadway safety, as it directly impacts a driver's ability to execute steering, braking, and acceleration maneuvers safely. Ensuring an adequate level of pavement friction is essential to minimize the skidding risk for all road users. Continuous pavement friction measurement (CPFM) has recently become a proven approach, revolutionizing safety-related pavement management and skidding crash injury prevention. Meanwhile, pavement roughness has long been linked to vehicle fuel efficiency and pavement structural degradation. Perceptions of pavement …

Using a mixed-methods ethnographic approach, including participant observation, archival review, spatial analysis, surveys, and interviews, the research investigates how THJCA affiliates conceptualize and respond to gentrification, space, and community change. Employing urban place theories and social capital frameworks, the research challenges deficit-oriented narratives in examining the experiences of current and former residents, the effects of gentrification on youth educational services, and THJCA's strategies for maintaining …

Statistical Methods For Interpreting Spatial And Temporal Heterogeneity Of Martian Tropical Water Ice Informed By Properties Of Crater Ejecta Types, Jamie D. Riggs, Michelle R. Kirchoff

College of Population Health Faculty Papers

The martian tropical water ice spatial and temporal distribution was characterized using impact crater ejecta type, location, size, and age in one of two epochs, (Formula presented.) Ga and (Formula presented.) Ga, using statistical models designed for spatial and temporal correlation structures. The indicator thought to identify the presence of ice is craters with layered ejecta, while the indicator thought to identify no ice is craters with radial ejecta. These indicators imply the location (longitude and latitude) and, potentially, depth (crater diameter as a proxy) of ice, and when the ice was present. The spatial and temporal distribution of layered …

Consensus Definition Of A Radiologically Healed Fistula On Magnetic Resonance Imaging In Perianal Crohn's Disease: An International Delphi Study, Easan Anand, Jalpa Devi, Shivani Joshi, Anna Antoniou, Michelle Doering, Jaap Stoker, Phillip Lung, Ailsa L Hart, David H Ballard, Parakkal Deepak, Phil Tozer

2020-Current year OA Pubs

INTRODUCTION: Perianal fistulising Crohn's disease (pfCD) is a distinct and debilitating phenotype seen in around one-third of patients with CD. Clinical trials in pfCD are increasingly using magnetic resonance imaging (MRI) criteria as a primary endpoint, but there is heterogeneity in the radiological definition of a healed perianal fistula that currently limits our ability to perform meaningful meta-analyses of studies. Our aim is to standardise outcomes through the generation of an international consensus definition of a radiologically healed fistula.

METHODS AND ANALYSIS: This international Delphi consensus study employs a two-part strategy.The first is a systematic review to identify a longlist …

Seeing The Blind: Humanism And The Experience Of Place, Joshua F. J Inwood

The Geographical Bulletin

Since much of our world is visually based, many researchers question how the "non-sighted " fit into this larger framework. Whereas many geographers have looked at navigation this paper will explore how the blind ascribe a practical understanding of the world that is constructed largely by and for those with sight. Because much of the relevant data involve perceptions not easily understood, this paper relies on qualitative methods, specifically the open-ended interview, to construct personal narratives. These narratives are analyzed using a humanistic perspective.

More Than A Place For Social Capital Creation: Public Library As A Place For Immigrants’ Social Integration, Nafiz Z. Shuva

Publications and Research

Studies have shown that public libraries, one of the most trusted social institutions, play an important role in helping immigrants adjust to their host country. Although there have been quite a few international studies reporting the role that public libraries play in newcomers lives in the host country, few studies, especially in the context of the U.S., comprehensively reported local public libraries’ role in newcomers’ social integration. Previous studies on immigrants’ usage of public libraries have mainly focused on highlighting public libraries as meeting places that facilitate social capital creation for newcomers or describing the usage of public libraries among …

Powerful Women—A Man-Made Fear: Unmasking The Vilification Of Women In Literature Through The Lens Of Jean Grey, Maximillan Wilson

Master of Liberal Studies Projects

Comic books in their current form have been a staple of American pop culture for nearly a century. The combination of art and narrative provides a unique storytelling medium that has evolved with each new batch of artists and authors over the decades. The imagination's impossible and fantastical qualities are actualized in ways that non-visual literature cannot compete with, reaching audiences of all ages and reading comprehension. However, like with all fiction, the influence of reality cannot be denied. Despite the colorful costumes and progressive storylines, comic book stories suffer from a long-standing misogynistic motive that has long plagued literature. …

Safe Reinforcement Learning For Intersection Management In Riti Communities Under Rare Extreme Events, Yuanzhang Xiao

CSET Project Reports

The rapid advancement of artificial intelligence (AI) is reshaping the transportation sector, with applications spanning autonomous vehicles, driver injury prevention, and traffic management. Efficient traffic management, particularly through adaptive intersection control, holds significant potential for reducing congestion. This study explores the application of reinforcement learning (RL) to adaptive traffic signal control in rural, isolated, tribal, and indigenous (RITI) communities, which face unique challenges such as rare extreme weather events. Standard RL approaches struggle in these contexts due to limited exposure to these rare events. In our study, we first evaluate several mainstream RL algorithms and identified two most promising approaches. …

Best Practice Advice For Asthma Exacerbation Prevention And Management In Primary Care: An International Expert Consensus, Neil Skolnik, Barbara P. Yawn, Jaime Correia De Sousa, María Mar Martínez Vázquez, Amanda Barnard, Wendy L. Wright, Austin Ulrich, Tonya Winders, Stephen Brunton

Department of Family & Community Medicine Faculty Papers

Primary care clinicians play a key role in asthma and asthma exacerbation management worldwide because most patients with asthma are treated in primary care settings. The high burden of asthma exacerbations persists and important practice gaps remain, despite continual advances in asthma care. Lack of primary care-specific guidance, uncontrolled asthma, incomplete assessment of exacerbation and asthma control history, and reliance on systemic corticosteroids or short-acting beta2-agonist-only therapy are challenges clinicians face today with asthma care. Evidence supports the use of inhaled corticosteroids (ICS) + fast-acting bronchodilator treatments when used as needed in response to symptoms to improve asthma control and …

Horticulture Faculty Publications and Presentations

Introduction:

Soybean is an important protein and oil crop, and improving yield has traditionally been a major breeding goal. However, salt stress is an important abiotic factor that can severely impair soybean yield by disrupting metabolic processes, inhibiting photosynthesis, and hindering plant growth, ultimately leading to a decrease in productivity.

Methods:

This study utilized phenotypic and genotypic data from 563 soybean germplasms sourced from over 20 countries. Employing four distinct models—we performed a genome-wide association study (GWAS) using four models, including MLM, MLMM, FarmCPU, and BLINK in GAPIT 3, we conducted a Genome-Wide Association Study (GWAS) to identify single nucleotide …

Measuring And Modeling Grease Degradation, Alan Gurt

LSU Doctoral Dissertations

Lubricating grease is an ideal lubricant for many devices such as roller bearings, journal bearings, slide bearings, gears, and many types of joints due to its simplicity. Once grease is put in place, it can often provide adequate lubrication for extended periods of time without the need for a complex supply system that would generally be needed for oil lubrication. However, during prolonged use, various degradation mechanisms change the physical and chemical properties of grease, possibly leading to inadequate performance and machinery failure.

In order to succinctly quantify the degradation of grease, it is essential to have robust, meaningful test …

Forensicllm: A Local Large Language Model For Digital Forensics, Binaya Sharma

LSU Master's Theses

Large Language Models (LLMs) excel in diverse natural language tasks but often lack specialization in fields like digital forensics. Their reliance on cloud-based APIs or high-performance computers restricts their use in resource-limited environments, and response hallucinations could compromise their applicability in forensic contexts. We introduce ForensicLLM, a 4-bit quantized LLaMA-3.1-8B model fine-tuned using Retrieval Augmented Fine-tuning (RAFT) on 6,739 Q&A samples extracted from 1,082 digital forensic research articles and curated digital artifacts. Evaluation on 2,244 Q&A samples showed that ForensicLLM outperformed the base LLaMA-3.1-8B model by 4.06%, 5.43%, and 15.79% on BERTScore F1, BGE-M3 cosine similarity, and G-Eval, respectively. Compared …

Simulations, Modeling And Data Analysis Of Parity Violating Electron Scattering Experiments, Yufan Chen

Doctoral Dissertations

In the Standard Model (SM) of nuclear and particle physics, parity violation is incorporated through the representation of the weak interaction as a chiral gauge interaction. Only the left-handed components of particles and right-handed components of antiparticles participate in weak interactions in the Standard Model. This implies that parity is asymmetric for the weak interaction. Parity violating electron scattering (PVES) experiments are designed to probe the physics parameters related to the SM, with the possibility to discover physics beyond the SM (BSM) by measuring the parity violating asymmetry 𝐴𝑃𝑉 of longitudinally polarized electrons scattered off unpolarized targets with high precision. …

Therapeutic Potential Of Astrocyte-Derived Extracellular Vesicles In Mitigating Cytotoxicity And Transcriptome Changes In Human Brain Endothelial Cells, Ruth Juliana Stewart

Doctoral Dissertations

Extracellular vesicles (EVs) play a major role in cell-to-cell communication via the horizontal transfer of RNA, DNA, proteins, and lipids that affect the physiological response of the recipient cells. Astrocytes are a type of glial cell that exerts a protective effect on neurons and brain endothelial cells. The astrocytes and the endothelial cells form the blood-brain barrier. Due to their nano-size and non-complex structure, EVs can efficiently cross the blood-brain barrier. This study investigated and assessed the impact of EVs on reducing oxidative DNA damage in human brain endothelial cells (HBECs). The protective potential of astrocyte-derived EVs was determined by …
