Sequestration Of Plant Defenses By Spotted Lanternfly (Lycorma Delicatula) And Effects On Avian Predators, Anne E. Johnson, Allison Cornell, Fang Zhu, Ashley E. Shay, Gabrielle Davis, Kelli Hoover

Biology Faculty Publications

Lycorma delicatula is a polyphagous phloem feeder, which is spreading rapidly in the U.S., and is a major threat to grapes, hops, and ornamentals. Among its hosts, L. delicatulaprefers Ailanthus altissima, an invasive tree from which it sequesters toxins, including several quassinoid compounds. We tested how these defenses affected predation by birds of nymphal and adult L. delicatula. Freeze-killed nymphs of each instar were reared with or without access to A. altissima and placed into cups on top of nest boxes occupied by house wrens (Troglodytes aedon). House wrens ate or fed their chicks a …

The C-Terminal Regions Of Trak Proteins Contain Miro-Independent Mitochondrial Localization Domains, Lili Mitchell, Kathryn E. Reda, Hijab Fatima, Claudia E. Vasquez, Omar A. Quintero-Carmona

Biology Faculty Publications

Current models suggest that MIRO GTPases anchor cytoskeletal motors to the mitochondrial outer membrane (MOM). However, our previous findings indicate that the unconventional myosin, MYO19, interacts with MIRO weakly and that a MIRO-independent MOM-localizing domain interacts more tightly with the MOM. To test the hypothesis that other MIRO interactors may also have MIRO-independent MOM binding, we examined interactions between TRAK proteins (microtubule motor-mitochondria adaptor proteins) and the MOM via quantitative fluorescence microscopy and steady-state kinetic approaches. Using GFP-TRAK truncations expressed in MIRO1-2 double knockout mouse embryonic fibroblasts, we identified a MIRO-independent mitochondrial-binding domain in the C-terminus of TRAK1 and TRAK2, …

Community, Autonomy, Irony: Lessons From Historic Rosenwald Schools, Ronald B. Matus

USF Tampa Graduate Theses and Dissertations

Growing evidence suggests the Rosenwald schools of the American South, which anchored thousands of Black communities for a half century before desegregation, boosted academic outcomes for generations of Black students and helped fuel the civil rights movement. The research literature, however, is thin on what specifically made these schools successful. My research attempts to narrow the gaps by asking the Rosenwald alums themselves. Through semi-structured interviews, 10 alums in Florida identify defining features of their schools, including seamless community connections; a culture of high expectations for academic achievement and character development; and especially caring and committed teachers. The alums’ insights …

Ai-Assisted Spectral Fingerprinting Of Mg-Doped Zno Tracer Phosphors: Tuning Photoluminescence Emission And Investigating Lifetime Via Sol-Gel Synthesis Parameters, Thomas M. Brandte

USF Tampa Graduate Theses and Dissertations

Plastic sorting remains a major driver of recycling costs, and existing infrared (IR) optical identification systems cannot determine material prominence or quality, nor reliably identify dark polymers [1]. This work explores a PVA-stabilized sol–gel and thermal synthesis route for magnesium-doped zinc oxide (Mg:ZnO) as a tunable photoluminescent tracer phosphor.

Lattice-defect control forms the foundation of phosphorescent emission tuning, enabling unique spectral fingerprints to be generated based on synthesis parameters—Mg molar ratio (Mg%), PVA mass (g), and calcination temperature (°C). Photoluminescence (PL) spectra (400–850 nm) were analyzed using Gaussian peak fitting and principal component analysis (PCA), reducing hundreds of spectral features …

Cdk4/6 Inhibitors In Breast Cancer-Who Should Receive Them?, Ahmed Elkhanany, Natalie C Chen, Eric C Chang

Faculty, Staff and Students Publications

More than 70% of breast cancers are estrogen receptor-positive (ER+). Endocrine therapy that blocks estrogen signaling remains the cornerstone of treatment, yet relapses continue to affect many patients. Cyclin-dependent kinases 4 and 6 (CDK4/6) regulate the G1-S phase transition in the cell cycle, and pharmacological inhibition of this pathway has been successfully leveraged to reduce recurrence. CDK4/6 inhibitors combined with endocrine therapy are now the standard of care, although determining the optimal patient population for treatment remains a key challenge. A newly published study provides important insight, showing that loss of the NF1/neurofibromin tumor suppressor confers greater sensitivity to CDK4/6 …

Hibben 105

The history of colonialism in the American West is not just the story of how European people, animals, and technologies invaded Indigenous worlds but also of how these things were engaged, redeployed, countered, rejected, and, in some cases, embraced by native communities. In this paper, I look beyond the horses, guns, germs, and steel that have dominated materialist analyses of the colonial encounter to consider the circulation of images—or more precisely, the circulation of new understandings of what images are and how they function. My focus is on the “Biographic Tradition,” …

Fuel Adulteration Detection Using Open-Ended Coaxial Line And Circular Waveguide Techniques, Abdulrahman Alofi, Ahmed Shamseldin, Sharif Iqbal M. Sheikh, Hussein Attia

Faculty Publications

Fuel adulteration, the practice of blending lower-quality substances like kerosene with gasoline, poses significant challenges for ensuring fuel quality and safety. This study investigates two electromagnetic-based methods for detecting such adulteration: the open-ended coaxial line method and the circular waveguide method. The results reveal that the open-ended coaxial line technique is particularly effective in detecting kerosene contamination, identifying levels as low as 10% by measuring changes in the dielectric constant of the gasoline-kerosene mixture. Operating in the frequency range of 0.25–1.25 GHz, this method captures subtle changes in permittivity. In contrast, the circular waveguide method evaluates contamination by monitoring shifts …
