The Heterogeneous Response Of Astrocytes In Different Brain Regions Under Metabolic Stress, Pawan Kumar Thapaliya

USF Tampa Graduate Theses and Dissertations

Astrocytes play a central role in maintaining ionic homeostasis, neurotransmitter clearance, and brain en-ergy metabolism. Their excitability, reflected in activity-evoked intracellular sodium (Na+, [Na+]i) and calcium (Ca2+,[Ca+]i) dynamics, is increasingly recognized as a critical determinant of neuronal function and vulnerability, particularly under metabolic stress. Despite their importance, the mechanisms underlying astrocytic ionic signaling and its regional heterogeneity remain incompletely understood. In this thesis, I developed detailed computational and biophysical models to investigate astrocytic Na+ and Ca2+ dynamics, their bioenergetic consequences, and the roles of key ion transporters under physiological and metabolically stressed conditions, validating the models against experi- mental data. …

Motivating Lung Cancer Screening Uptake: An Experimental Test Of Didactic Versus Narrative Messages For Lung Cancer Screening Among Individuals Who Currently Smoke Or Formerly Smoked, Honor M. Woodward

USF Tampa Graduate Theses and Dissertations

Lung cancer is the number one cause of cancer-related death in the United States and worldwide. Lung cancer screening with low-dose computed tomography (LDCT) has been associated with a 20% reduction in lung cancer-related mortality. Despite the obvious benefits of lung cancer screening with LDCT, screening is heavily underutilized compared to other cancer screening tests. Thus, it is critically important to develop strategies that help motivate screening uptake among eligible individuals. This study explored the effectiveness of narrative messages for motivating lung cancer screening uptake among individuals eligible for lung cancer screening who currently smoke or formerly smoked. Drawing from …

Their use has been tested to monitor air temperature inside the Abisso Bonetti Cave (Classical Karst, Italy), proving for the first time that a cave in Gorizian Karst can systematically be colder than the outdoor temperature even in winter, recording an internal temperature even lower than 0°C. The Dolphin device can be …

Microarchitectural Vulnerabilities And Performance Tradeoffs In Shared Scientific Computing, Zyad Abd-Elrahman, Santosh Pandey

Bellini College REU Symposium (BCREUS)

Introduction & Problem Statement

Shared scientific computing platforms are built for speed and utilization, but they create a security problem that isolation alone can't fully solve. Even with TEEs, containers, or a privilege separation in place, the hardware underneath remains a shared resource. Speculative execution, cache contention, interconnect timing, and similar microarchitectural effects can leak information or create integrity risks across protection boundaries without any malicious code involved. For CI operators running graph workloads, HPC kernels, or ML pipelines in co-tenanted systems, the threat is inherent in normal execution. The real question isn't whether these vulnerabilities exist, but it's what …

An Evaluation Of Biologically-Inspired Slam Models Against Traditional Models, Colby Mullins, Asadbek Nematov, Ross Volenec, Chance Hamilton, Alfredo Weitzenfeld

Bellini College REU Symposium (BCREUS)

This research presents a comparative analysis of biologically-inspired SLAM models (RatSLAM [2], SeqSLAM [3]) versus traditional feature-based geometric SLAM (ORB-SLAM3 [1]) to establish a standardized framework for evaluating accuracy, robustness, and computational efficiency under varying environmental conditions. To ensure an equitable baseline, models are subjected to a unified testing pipeline across real-world datasets (Oxford RobotCar clear and overcast sequences) and controlled Webots simulations (day/night and seasonal centerlines) using timestamp-aligned 480p monocular PNG images. Within this pipeline, pose estimations are standardized to the TUM trajectory format, and spatial alignment and scale correction are applied via the evo evaluation library [4] to …

Beyond Folded Proteins: Assessing The Limits Of Ai Structure Prediction For Intrinsically Disordered Complexes, Juan Velasquez, Faith Robinson, Sebastien Ghent, Taseef Rahman

Bellini College REU Symposium (BCREUS)

Introduction & Problem

Intrinsically disordered proteins (IDPs) and their associated “fuzzy” complexes represent a major unresolved challenge in structural biology. Unlike traditional protein complexes that adopt stable, well-defined tertiary structures, fuzzy complexes retain conformational heterogeneity even in the bound state [1]. This dynamic behavior is functionally important in processes such as transcriptional regulation, signaling, and phase separation, but it complicates both experimental characterization and computational prediction. Recent advances in deep learning-based protein structure prediction, particularly AlphaFold2 and its successors, have demonstrated near-experimental accuracy for ordered proteins [2]. However, these models are fundamentally trained on static structural data, primarily derived from …

(Re)Imagining Research-Practice Collaboration And Partnership: Constructivism By Way Of Interdisciplinarity, Multimodality, And Humanity, Bethany Silva, Alecia Magnifico, Laura Allen, David Baroody, Ashley Barry, Shawna Coppola, Cathy Fraser, Emily Geltz, Anne Mcquade, Christina M. Ortmeier-Hooper, Laura Smith, Donna Turco

Journal of Practitioner Research

Research-Practice Partnerships (RPPs) have become an important vehicle for educational research. By connecting researchers and educators, RPPs can couple systematic research and practical application. However, relational practices for building research collaboratives are understudied, and RPPs often reinscribe power imbalances among practitioners and researchers. With its focus on the centrality of practitioners and their knowledge, practitioner research offers possibilities for disrupting such power imbalances. In this reflective essay, our team describes our efforts to harness practitioner research’s capacity to identify and address salient school-level issues and RPPs’ power to impact a wider audience. We identify practices to build relationships, inform research …

Breathing Life Into Sel: A Practitioner Inquiry On Hā, Belonging, And Multilingual Learners In Hawai‘I, Mylia Briggs, Monica Gonzalez Smith

Journal of Practitioner Research

This practitioner inquiry explores how a Pacific-oriented social-emotional learning (SEL) framework, Nā Hopena A‘o (HĀ: BREATH), can affirm the cultural identities and emotional well-being of Filipino multilingual learners (MLs) in Hawai‘i. Implemented over a 15-week period in a third-grade classroom, the study draws on culturally adapted SEL lessons, student exit tickets and focus groups, and teacher reflections to examine how SEL shifts when grounded in Indigenous values, heritage language use, and community knowledge. Findings reveal three key themes: (1) Cultural Connection Fosters Belonging, (2) Language Visibility Promotes Emotional Safety, and (3) Identity-Affirming Practices Build Confidence and Voice. While students responded …

Exploring Researcher-Practitioner Authorship Collaboration In English, Foreign Language, And Mathematics Education, Rachel Cullen, Joseph Taylor, Matthew Laney, Mohamed Nouri

Journal of Practitioner Research

This study examined collaboration and bidirectional relationships between researchers and practitioners in the context of journal publications. Through exploration of research and practitioner journals in the areas of English, Foreign Languages, and Mathematics, we aimed to understand how authorship patterns and types of references illustrate the gap between research and practice. Findings indicate that collaboration between researchers and practitioners in the context of journal publications is minimal, and practitioner presence is scarce in research. The types of references included in publications are high quality regardless of authorship, but there is a problem of exposure that limits the research from reaching …

The Materiality Of Religious Syncretism And Co-Production In The Catacombs Of Sicily And Malta: Novel Techniques For The Interpretation And Dissemination Of Legacy Data, Madeleine A. Kraft

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the lengthy history of the investigations into the catacombs of Sicily and Malta. These investigations, in some cases, began as early as the 17th century. They have maintained the intrigue of archaeologists beginning in the late 19th century. In doing so, these spaces have amassed truly remarkable amounts of data and of interpretations of that data. This legacy data has proved simultaneously a barrier and an entrance to understanding these complexes. While they are valuable for descriptions of the spaces prior to mutilations and interventions as well as descriptions of evidence no longer extant due to a …
