Engineering 3d Optical Interconnects And Low-Power Radio Frequency Gaze Tracking, Blake P. Crosby

Theses and Dissertations

This thesis presents two independent research works in optical in- terconnects and radio-frequency (RF)-based gaze tracking. The first work demonstrates a silicon optical waveguide fabricated from four through-silicon vias (TSVs) produced using two-photon-absorption- assisted photo-electrochemical etching. Unlike conventional TSV fabrica- tion methods, this approach enables highly localized, non-line-of-sight etching in silicon using a focused femtosecond laser. Four approximately 5 μm diameter TSVs were etched through a 200 μm silicon wafer in a 7 μm by 7 μm pattern, leaving a central silicon region that functions as a waveguide. The fabricated structure achieved an aspect ratio of approxi- mately 40:1 with …

This study evaluated the effects of a peer mentor program for newcomer students on their feelings of peer connectedness and school belonging in a high school setting. Participants were made up of 15 newcomer student mentees across three high schools. Measures were administered pre- and post-intervention, and participants were also interviewed about their experience. Results indicated no quantitative findings of significance but did yield a small positive effect size for peer connectedness. According to qualitative data, many participants …

Hierarchical Parcel Swapping: A Novel Model In Turbulence, Masoomeh Behrang

Theses and Dissertations

Turbulent mixing plays a central role in a wide range of engineering and natural systems, particularly in reactive flows where turbulence--chemistry interactions strongly influence reaction rates, flame structure, and emissions. Accurately modeling these interactions remains a major challenge due to the multiscale and stochastic nature of turbulence, as well as the nonlinear coupling between transport and chemical kinetics. This dissertation develops and evaluates the Hierarchical Parcel Swapping (HiPS) model, a fully stochastic framework designed to represent turbulence-driven transport and scalar mixing without relying on traditional gradient-based closures. HiPS is investigated both as a standalone turbulence model and as a subgrid …

Service Providers' Descriptions Of Survivors' Experiences With Mental Health Treatment, Melanie Gonzales Puente

Theses and Dissertations

Human trafficking survivors experience significant mental health challenges and barriers that limit their engagement towards treatment. A qualitative study was conducted that included semi-structured interviews of 33 professionals working with survivors of human trafficking in the United States. Findings indicate that survivors' engagement in treatment is limited by mistrust of providers, stigma, and a lack of access to services. Providers emphasize that addressing basic needs (e.g., safety and housing) must occur before engaging in trauma-focused therapy. Positive outcomes are associated with strong therapeutic relationships, autonomy, trauma-informed, individualized care, and offering comprehensive services. Furthermore, mental health providers should have certain abilities …

Hormonal Shifts And Structural Strain: A Literature Review Of Menopause And Perimenopause In Relation To Overuse Injuries And Stress Fractures, Mustafa Ansari, Faisal Hussain, Mutasem Shopon, Hanfa Ajmal, Mueez Asif, Sharon David

Student Publications

Musculoskeletal injury risk in midlife women has traditionally been attributed to estrogen decline, but this narrow focus overlooks the broader biomechanical, neuromuscular, and structural changes associated with menopause. Estrogen plays a multisystem role in maintaining trabecular bone integrity, collagen turnover, and neuromuscular coordination. Its abrupt loss causes bone demineralization (2%-5% annually in early menopause), impairs tendon repair, and contributes to sarcopenia. Fluctuating estradiol levels during perimenopause may transiently increase ligament laxity, further destabilizing joints. Common injuries such as Achilles and rotator cuff tendinopathies, plantar fasciitis, and stress fractures are amplified by low bone mineral density, prior fracture history, aromatase inhibitor …

Can Hope Be Changed In 30 Minutes? The Development, Refinement, And Pilot Evaluation Of A Hope-Based Single-Session Intervention, Aileen Kangavary

USF Tampa Graduate Theses and Dissertations

Background: Although mental health problems are on the rise among youth, nearly 80% do not access treatment. Schools serve as key settings to address adolescent mental health and wellness needs given the substantial barriers that limit access to community-based mental health services. Despite this potential, schools often face implementation challenges. Therefore, scalable and accessible approaches are needed to meet the growing demand for adolescent mental health support. Single-Session Interventions (SSIs) represent a promising, cost-effective, and digital avenue for providing timely mental health support to youth. Increasingly, research conceptualizes mental health through a two-dimensional framework that includes the presence of well-being …

Rheological Protocol To Assess And Optimize Latex Coagulation Dynamics For The Thin Glove Coagulant Dipping Process, Monday U. Okoronkwo, Kok Kong Ng, Wolfram Franke, Gaurav Sant

Chemical and Biochemical Engineering Faculty Research & Creative Works

Many products that directly impact the quality of human life today — gloves, catheters, condoms, and baby bottle teats — are made through the latex-dipping technology. While a variety of methods have been developed – e.g., particle counting, turbidimetry, microscopy, and light scattering – which are suitable for studying the coagulation of latex at very low concentrations, much less work has focused on methods suitable for in-situ characterization of latex coagulation in concentrated solutions (e.g., as relevant to the dipping process). This paper presents a process-relevant rheological protocol for assessing and optimizing latex coagulation dynamics for the thin glove coagulant …

Searches For Continuous Gravitational Waves From Supernova Remnants In The First Part Of The Ligo-Virgo-Kagra Fourth Observing Run, A. G. Abac, I. Abouelfettouh, Teviet Creighton, Mario C. Diaz, Raul Alberto Espinosa Perez, J. Lawrence, Francisco Llamas Villarreal, Soma Mukherjee, Volker Quetschke, Miriam Ramos Arevalo, Wenhui Wang

Physics & Astronomy Faculty Publications

We present results from directed searches for continuous gravitational waves from a sample of 15 nearby supernova remnants, likely hosting young neutron star candidates, using data from the first eight months of the fourth observing run (O4) of the LIGO–Virgo–KAGRA Collaboration. The analysis employs five pipelines: four semicoherent methods—the Band-Sampled-Data directed pipeline, Weave, and two Viterbi pipelines (single- and dual-harmonic)—and PyStoch, a cross-correlation-based pipeline. These searches cover wide frequency bands and do not assume prior knowledge of the targets’ ephemerides. No evidence of a signal is found from any of the 15 sources. We set 95% confidence-level upper limits on …

A Role For The Poly-Asparagine Repeat In The Plasmodium Histone Acetyltransferase, Pfgcn5, Kelly Rubiano, Aaron Morris, Francisca D L Vitorino, Jasper Travis, Benjamin A Garcia, Sumit Mukherjee, Daniel E Goldberg

2020-Current year OA Pubs

Plasmodium falciparum possesses one of the most AT-rich genomes in nature (80.6%). A consequence is an asparagine-rich proteome. A quarter of P. falciparum proteins possess poly-asparagine repeats that can extend more than 100 residues. The role of these repeats has remained a mystery in the biology of this parasite. Here, we report that the poly-asparagine repeat-containing Nterminus of the histone acetyltransferase PfGCN5 associates with the C-terminal catalytic domain after cleavage in the nucleus. Deletion of the repeat destabilizes the N-terminal polypeptide, leading to impaired parasite development and growth, particularly under stress conditions. Using high-resolution mass spectrometry and western blotting analysis, …

We also provide detailed source property measurements for 86 of these that have a false-alarm rate …

Fragile Hope And The Cultural Life Of Law, Shefali Jain

Socio-Legal Review

This review of Sandhya Fuchs’ Fragile Hope: Seeking Justice for Hate Crimes in India (Stanford University Press 2024) highlights that the book makes a genuinely original ethnographic and conceptual contribution to caste studies and hate crime scholarship. At the same time, the essay argues that there are three limitations to its framework that require greater engagement: the book’s failure to engage with the legal consciousness tradition in socio-legal scholarship, an underdeveloped account of “legal meliorism,” and an unresolved tension between the book’s stated commitment to victim-centred analysis and its ethnographic evidence that frequently discusses movement-level aspirations.

Physics & Astronomy Faculty Publications

GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is consistent with a binary black hole coalescence with component masses m1=33.7+2.9−2.2M⊙, m2=29.9+2.1−2.8M⊙, and a small effective inspiral spin χeff=−0.01+0.06−0.07. The high signal-to-noise ratio enabled us to detect an ℓ = ∣m∣ = 4 mode in the inspiral–merger–ringdown signal for the first time (with Bayes factor ≈10), as well as enabling a range of tests of consistency between theoretical predictions and the observed waveform. While most of these tests show agreement with theoretical predictions, there are …

A Multilevel Analysis Of Hiv Care Outcomes Across Age, Race, And Housing Among United States Women Veterans, Liang Chen, Emmanuel Guajardo, Maria E Fernandez, Cici Bauer, Irene Tamí-Maury, Jan Lindsay

Faculty, Staff and Students Publications

Background: Women veterans with HIV represent a growing, diverse population within the Veterans Health Administration (VHA). This study examined HIV care continuum outcomes among women veterans using a multilevel intersectional approach.

Methods: We conducted a retrospective analysis of 1154 women veterans with HIV in VHA care in fiscal year 2022, with outcomes assessed in fiscal year 2023. We applied Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) to evaluate how combinations of social positions (age, race/ethnicity, housing status) were associated with HIV outcomes.

Results: MAIHDA models showed that younger age (< 45 years) and being unhoused were consistently associated with lower odds of care engagement and viral suppression than midlife (45-64) and older (65+) housed women veterans. Additionally, predicted probability analyses revealed distinct clustering patterns. Younger non-Hispanic White women consistently ranked among the lowest performing strata across all outcomes, while midlife and older Hispanic and non-Hispanic Black women veterans clustered among the highest. Variance Partition Coefficients from null models were modest (1.8-3.0%). Fully adjusted models showed no remaining between-stratum variance, suggesting that the included social positions explained the observed differences in our dataset.

Conclusions: These findings highlight disparities in HIV care …

From Unfinished Sentences To Unfinished Degrees: A Reflection On Students’ Struggles With Academic Writing In The Context Of Retention In Higher Institutes Of Education, Irina Ruppo

Irish Journal of Academic Practice

This article explores the experiences and beliefs of students whose struggles with academic writing had led to contemplation of withdrawal from the university. It proposes that the absence of writing as a separate factor in existing retention models obscures the importance of writing issues to students’ persistence with their chosen course of study. Through a qualitative analysis of in-depth interviews with undergraduate students, the article suggests that students’ struggles with writing may be distinct from their overall difficulties with the workload. Four beliefs about academic writing are identified as potentially contributing to the students’ malintegrative experience within the institution. Seeing …
