Evaluating Potential Changes From Nitrogen To Phosphorus Nutrient Limitation Of Phytoplankton Growth In North Inlet Estuary, Catherine Schlenker, James L. Pinckney

Faculty Publications

In marine systems, molar ratios of the biolimiting inorganic nutrients, nitrogen (N) and phosphorus (P), are assumed to follow the “Redfield ratio” (N:P = 16:1), which is often used to infer nutrient limitation of phytoplankton biomass. Traditionally, estuaries are considered N-limited (N:P <  16) but with higher coastal N-loading, reports of P-limitation (N:P > 16) have increased. In recent decades, nutrient loading in North Inlet Estuary (NIE) has changed such that dissolved inorganic nitrogen (DIN):dissolved inorganic phosphorus (DIP) ratios increased from ca. 7 to 20 (2002–2021). This suggests that primary production in NIE may be transitioning from N-limitation to NP co-limitation or primary P-limitation. Due to high N:P ratios, we hypothesized that …

Chemotype- And Target-Driven Genome Mining For A New Natural Product Inhibitor Of Bacterial Peptide Deformylase, Jonas H Costa-Martini, Eva E Adams, Chad W Johnston

Faculty, Staff and Students Publications

Antibiotics are essential for modern medicine, but their use drives the evolution of antimicrobial resistance (AMR) that limits the long-term efficacy of any one drug. To keep pace with AMR and preserve our ability to treat bacterial infections, it is essential that we identify antibiotics with new structures and targets that are not affected by clinical resistance. Historically, most developmental candidates for antibiotics have come from microbial natural products, as they feature chemical structures and biological activities that have been honed over millions of years of evolution. Unfortunately, as classical bioactivity screens for natural product discovery are blind to the …

Background: Experimental data from functional assays have a critical role in interpreting the impact of genetic variants. Assay data must be unambiguously mapped to a reference genome to make it accessible, but it is often reported relative to assay-specific sequences, complicating downstream use and integration of variant data across resources. To make multiplexed assays of variant effect (MAVE) data more broadly available to the research and clinical communities, the Atlas of Variant Effects Alliance mapped MAVE data from the MaveDB community database to human reference sequences, creating an extensive set of machine-readable homology mappings that are incorporated into widely used …

The Role Of Langmuir Circulation In Coastal Flows Driven By Wind, Waves And Tides, Thathsarani Dilini Herath Herath Mudiyanselage

USF Tampa Graduate Theses and Dissertations

Langmuir Circulation (LC) is a wind and wave-driven process and is a key driver of vertical mixing and transport in the ocean. In coastal shelf regions, LC can span the entire water column, linking surface and bottom boundary layers and amplifying turbulent mixing. However, the influence of LC on vertical mixing and cross-shelf transport in shallow, tidally forced coastal waters remains poorly understood. This dissertation addresses this knowledge gap by developing a novel modeling framework based on the Reynolds-Averaged Navier–Stokes (RANS) equations, offering a computationally efficient alternative to more resource-intensive Large Eddy Simulations (LES).

The proposed RANS-based approach is first …

Does Practice Make Perfect? Examining The Impact Of Text-Based Reminders On Adherence In The Helping Our Toddlers, Developing Our Children’S Skills Program, Lauren Patrusky

USF Tampa Graduate Theses and Dissertations

Disruptive behavior disorders (DBDs) are prevalent in approximately 17% of children ages birth to 5 years (CDC, 2023). DBDs can significantly impact a child’s learning, social-emotional wellbeing, and ability to develop and maintain healthy relationship (CDC, 2023). Behavioral parent training (BPT) has been proven effective in reducing disruptive behavior and improving parent-child relationships. However, many families do not fully engage in treatment, leading to poor outcomes for both the child and the family. Chacko (2016) describes BPT engagement as enrolling in treatment, attending weekly sessions, participating in group discussions or role plays in sessions, practicing skills between sessions, and completing …

Kolmogorov–Smirnov-Based Edge Centrality Measure For Metric Graphs, Christina Durón, H. Kravitz, Moysey Brio

Mathematics and Statistics Faculty Publications and Presentations

In this work, we introduce an edge centrality measure for the Helmholtz equation on metric graphs, a particular flow network, based on spectral edge energy density. This measure identifies influential edges whose removal significantly changes the energy flow on the network, as indicated by statistically significant p-values from the two-sample Kolmogorov–Smirnov test comparing edge energy densities in the original network to those with a single edge removed. We compare the proposed measure with eight vertex centrality measures applied to a line graph representation of each metric graph, as well as with two edge centrality measures applied directly to each …

Data For: "Thresholds Of Wave Forcing: Implications For Atoll Reef Dynamics Under Sea Level Rise", Mathilde Lindhart, Gerd Masselink, Ashley Holsclaw, Tim Scott

Faculty of Science and Engineering Datasets

We investigate the response of shallow reef flow to tidal variability and wave exposure during a four-month field campaign in southern Huvadhu Atoll, Maldives. Incident waves breaking on steep fore reefs and reef crests generate a setup proportional to offshore wave height that drive a cross-reef flow. We identify a critical threshold—where the depth on the reef flat equals the depth at wave breaking—that separates two distinct reef flow regimes: one dominated by strong, unidirectional flow from the ocean into the lagoon, and another where wave breaking ceases, flow rates decrease, and occasionally reverse direction. Recognising the relative importance of …

A Review Of Plant–Microbe Interactions In The Rhizosphere And The Role Of Root Exudates In Microbiome Engineering, Anagha Wankhade, Emma Wilkinson, David W. Britt, Amita Kaundal

Biological Engineering Student Research

Microbial interactions within the rhizosphere are fundamental to plant health, influencing nutrient availability, stress tolerance, and pathogen resistance. Beneficial microbes, such as plant growth-promoting microbes (PGPMs), including bacteria and mycorrhizal fungi, enhance plant resilience through mechanisms like nutrient solubilization, phytohormone production, and pathogen suppression via antimicrobial compounds and siderophores. Root exudates, composed of sugars, organic acids, and secondary metabolites, act as chemoattractants that shape the rhizosphere microbiome by recruiting beneficial microbes. Microbial metabolites can, in turn, modulate plant physiology and exudate profiles, thereby reinforcing mutualistic interactions. Stress conditions alter exudate composition, enabling plants to attract specific microbes that aid in …

Exploring The Translation Lookaside Buffer (Tlb) For Low-Level Task Differentiation And Classification, Cristian Agredo, Daniel F. Koranek, Christine M. Schubert, Jose A. Gutierrez Del Arroyo, Tor J. Langehaug, Scott R. Graham

Faculty Publications

The primary focus of modern Central Processing Unit (CPU) technologies is performance improvement, with security often considered a secondary concern. As a result, vulnerabilities within the system are overlooked. While significant research, both offensive and defensive, has been conducted on CPU caches, relatively little attention has been given to the Translation Lookaside Buffer (TLB) due to its perceived lack of data granularity. Prior studies have typically combined multiple Hardware Performance Counters (HPCs) or relied on timing analysis to extract meaningful insights. In contrast, this study introduces a novel methodology that leverages only TLB related HPCs for multi-task classification, without incorporating …

A “Teaching As Emergent Learning” Approach To Teaching Deep Creativity, Steven Greenstein, Iain Kerr, Emily Olson

LASER Journal

Creativity is the process by which a change that is new and different emerges. We call it deep when it yields novel forms of both quantitative and qualitative change. If we are to take on the most pressing and persistent challenges to our social, global, and planetary well-being, we need novel approaches of a qualitatively different kind than those that have failed to bring about radical change in the past. In other words, we need deep creativity. The paradox at the heart of ``ideation-first" approaches to creative practice (e.g., brainstorming or ideating) is that if creativity aims to produce outcomes …

Silicon Sentinels: Using Whistleblower Protections To Manage Information Asymmetry And Ai Risk, Jason Green-Lowe, Fynn Fehrenbach, Mark Reddish

Liberty University Law Review

In the rapidly evolving landscape of artificial intelligence (“AI”) development, policymakers face a critical challenge: obtaining accurate and timely information about the potential risks and impacts of advanced AI systems. This Article examines the pivotal role of whistleblower protections as a mechanism to address the information asymmetry between AI companies and government officials. Employees inside AI companies are uniquely positioned to share information that can help outside regulators make wise policy decisions, but employees might be reluctant to do so unless their decision to share that information is legally protected. We propose a comprehensive framework for AI whistleblower protections as …

The Measure Of A Man: Considering Science Fiction And Christianity In The Regulation Of Artificial Intelligence Models, Andrew P. Connors

Liberty University Law Review

Does artificial intelligence “think,” and if it does, what should the law do about it? This article examines popular culture and the Turing Test to assess whether artificial intelligence “thinks,” applying the author’s engineering background and his Christian worldview. The author concludes that artificial intelligence mimics rather than creates and considers the risks and benefits of artificial intelligence given that conclusion. The author suggests that legal regulation should be measured, leaving important decisions to humans while at the same time encouraging development of this important, misunderstood technology.

Media Education: Growth And Controversy

Communication Research Trends

Media education has come a long way since 1977 when UNESCO made the first international survey. In industrialised countries of the West, media education is increasingly accepted as part of primary and secondary school education. In Australia and Britain, for example, it is now offered as an optional course, and in other countries it is taught as part of social studies, art or language/literature curricula. In regions such as Latin America there are programmes for working-class women in poor neighbourhoods or for rural families. There has been a boom in textbooks, teaching packs and audiovisual materials. Teacher training has long …
