Characterization Of Various Corrosion-Resistant Rebars Embedded In Concrete After 20 Years Of Exposure, Samantha Mavrak

Electronic Theses and Dissertations 2020 - Present

In aggressive marine environments, the deterioration of reinforced concrete structures is primarily caused by chloride-induced corrosion of embedded carbon steel reinforcement, resulting in concrete cracking, spalling, and costly maintenance or premature replacement. Corrosion-resistant reinforcement has been developed to mitigate these effects; however, long-term field performance data remain limited. This study evaluates the long-term corrosion performance of several corrosion-resistant rebars embedded in simulated deck slab concrete specimens following approximately 20 years of chloride exposure.

Concrete specimens containing 304SS, 316SS, and 2304 duplex SS, two types of clad reinforcement (316SS with carbon steel core), and an intermediate alloy with 12% Cr were …

Improving Cancer Diagnosis And Patient Outcomes With Deep Learning Models, Mariana Arriz-Jorquiera

USF Tampa Graduate Theses and Dissertations

Cancer care depends on timely and reliable decisions, from detection and diagnosis to treatment planning and patient monitoring. These decisions are often made under uncertainty because medical images and healthcare data may be noisy, incomplete, or difficult to interpret. In breast cancer imaging, ultrasound is widely used because it is safe, accessible, and complementary to other imaging modalities. However, variations in image quality, acquisition conditions, and noise can obscure lesion boundaries and texture, affecting human interpretation and artificial intelligence reliability. This dissertation develops deep learning, image-analysis, and optimization methods to improve healthcare decisions under imperfect information. Its primary focus is …

Mechanistic Basis Of Bifunctional Oxidation By A Non-Heme Fe(Ii)/2-Oxoglutarate-Dependent Enzyme Cctet Toward N6-Methyladenine And 5-Methylcytosine In Double-Stranded Dna, Bhargav Varada, Simahudeen Bathir Jaber Sathik Rifayee, Midhun George Thomas, Ethan Sommer, Carter Davis, Sodiq Waheed, Sudheesh Devadas, Surajit Kalita, Sreerag Melayikandy, Tatyana Karabencheva-Christova, Christo Christov

Michigan Tech Publications

CcTET (Coprinopsis cinerea ten-eleven translocation) is a non-heme Fe(II)/2-oxoglutarate (2OG)-dependent oxygenase that catalyzes the oxidative demethylation of both N⁶-methyladenine (6mA) and 5-methylcytosine (5mC) in double-stranded DNA, distinguishing it from other TET enzymes that act exclusively on 5mC. Despite this bifunctional activity, the molecular origins of its substrate selectivity and catalytic mechanism remain poorly understood. Here, we employed a multiscale computational approach combining classical molecular dynamics simulations and hybrid quantum mechanics/molecular mechanics calculations to characterize the conformational dynamics and reaction pathways of CcTET. Our results show that CcTET follows the canonical Fe(IV)=O-mediated mechanism, in which hydrogen atom transfer (HAT) …

The Implications Of Generative-Ai User Prompt Engineering Shaping The Absent Presence Of Latino Women Textual Rhetoric In Llms, Angely C. Suarez Dejesus

ELO (un)supervised 2026

This article examines how large language models (LLMs) generate text that affects underrepresented groups, particularly Latino women, due to limited cultural, contextual, and abstraction training rooted in biases. The research draws on Brock’s (2018) CTDA theory, White et al.’s (2023) prompt engineering framework, Klein’s (2015) computational spatiality, and Anzaldua’s (1987) concepts of cultural, emotional, and gendered borderlands to analyze the outputs. Using narrative prompt experiments, Chat GPT 3.5, 5, Claude AI, Gemini, and Microsoft Co-Pilot produced changes in their textual outputs as evidence of further algorithmic designs. Nevertheless, continual biases embedded in the algorithms’ linguistic representation and misrepresentation through the …

Post-Digital Creativity In Underacknowledged Communities, Tegan Pyke, Hannah Ackermans, Zahra Rizvi

ELO (un)supervised 2026

In a world marked by polarization and institutional censorship, what we pay attention to matters more than ever. We would almost forget that people, unsupervised, cannot help but be creative. Increasingly, this creativity takes the form of post-digital art and literature, often without awareness of “electronic literature” as a concept or the ELO as an institution. In this panel, we open up the conversation of researching post-digital creativity outside e-lit cultures to learn what role multimodality and participatory cultures (can) play inside e-lit cultures.

To encourage active participation in this online panel, we intend to split our session into two …

Quilt Poems: Encoding Craft Traditions As Generative Poetry, Lee Tusman

ELO (un)supervised 2026

This talk presents Quilt Poems, a generative literature project that finds unexpected common ground between quilting, data, and computational poetry. Beginning as a NaNoGenMo (National Novel Generating Month) entry, the project encodes a library of traditional quilt patterns as structured data, pairs them with a curated word corpus, and uses software to produce visual poems whose form is literally shaped by quilt geometries. I'll walk through the process of translating a tactile, domestic craft tradition into a formal data schema — the interpretive choices that entails, what gets lost and what gets discovered — and how that encoded knowledge …

Resolving The Jwst Cosmic Dawn Crisis And The Hubble Tension Via Non-Linear Elastic Strain Integration In The Dehp Substrate, Christopher L. Eckes

Defensive Publications Series

This technical disclosure formalizes a comprehensive, particle-free alternative to standard Lambda Cold Dark Matter (ΛCDM) cosmology by unifying the Dimensionally Extended Holographic Projection (DEHP) model, the Substrate Pushback Principle (SPP), and Informational Exomemory Cosmology (IEC). We demonstrate that the two most pressing crises in modern astrophysics—the James Webb Space Telescope (JWST) "Impossible Early Galaxy" problem and the 5.6 km/s/Mpc Hubble Tension discrepancy—are not independent anomalies, but rather the direct macroscopic consequences of treating space as a passive geometric vacuum instead of a pressurized, two-dimensional (2D) viscoelastic phase fluid substrate (z=0) running a real-time holographic rendering engine.

Ai To Ai Architecture: A Direct Latent-Space Tensor Routing Protocol & Immutable Neuromorphic Asic Architecture For Self-Regulating Milti-Agent Compute Networks, Christopher L. Eckes

Defensive Publications Series

Contemporary distributed Artificial Intelligence (AI) networks face critical limits in throughput, energy efficiency, and security due to their reliance on serialized -token interfaces (e.g., natural language, JSON, XML) for multi-agent cross-talk.

These traditional software-defined models introduce significant tokenization processing latency, suffer from compounding autoregressive gradient drift that causes runaway hallucination spirals over time, and present extensive vulnerability surfaces to adversarial prompt injections and gradient poisoning exploits.

This paper introduces a production-ready system architecture for a non-linguistic, machine-to-machine data routing engine and embedded cybersecurity shield, hardwired directly onto custom Neuromorphic Application-Specific Integrated Circuits (ASICs).

A Comparative Expression Analysis Of Selected Genes Involved In Secondary Metabolites Biosynthesis Among Three Alfalfa Cultivars Grown In Iraq, Izdehar Yahia Obaid, Bushra M. J. Alwash

Al-Bahir

Because of its abundance in proteins, vital amino acids, vitamins, and minerals that promote balanced nutrition, Medicago sativa L., also known as alfalfa, is regarded as a nutritionally excellent forage crop. In addition to its nutritional value, alfalfa produces a range of bioactive secondary metabolites, including flavonoids, alkaloids, and phenolic acids, further supporting its use in medicinal and nutritional applications. Three alfalfa cultivars grown in Iraq were examined for gene expression levels of the primary genes involved in secondary metabolite biosynthesis (PAL, COMT, CHS, and OMT). Among these cultivars are Victoria (VC), Green Gold (GC), and a local cultivar (LC). …

Bridge Scour Analysis For Rocks: Classification, Method Selection, And Practical Case Studies, Darud E. Sheefa, Stanley Vitton, Zhen (Leo) Liu, Brian Barkdoll

Michigan Tech Publications

Despite the availability of several scour calculation methods, bridge scour analysis for scour susceptible rocks is much less understood than its counterpart for sands, because scour calculation equations were traditionally obtained using flume tests with sands. As a result, there are three major knowledge gaps in the bridge scour analysis for susceptible rocks: (1) a rock classification system is needed for scour considerations to serve as a pre-screening process before conventional scour analysis involving sampling, erodibility testing, and scour calculation, (2) there has been a lack of information to guide the scour analysis for rocks including detailed procedures, needed and …

Applied Computational Models And Algorithmic Solutions To Common Optimization Problems In Energy-Water Systems, Michael Trosper, Paul Bodily

Idaho Conference on Undergraduate Research

Energy and water problems have a prevalence of optimization solutions. Yet operators, educators, and students working in these systems frequently lack tools that make the underlying optimization problems visible, tractable, or teachable. It has been noted that Dr. Bruce Savage, Chair of the Civil and Environmental Engineering Department at Idaho State University, has identified this gap directly, specifically noting that visualization and interactive learning tools of this kind could be transformative not only for K-12 students but for collegiate education as well. This research responds to that need by developing interactive, visualization-driven software that maps real-world energy-water challenges onto canonical …

Developing An Understanding Of Concavity Built On Covariation, Jade E. Gregg

Theses and Dissertations

This study investigated how six students developed a quantitative understanding of concavity founded in covariational reasoning through a series of task-based teaching interviews. A key finding was the importance of multivariational reasoning--the coordination of more than two variables--in helping students reason deeply about concavity in context. Common difficulties, including confusion about negative rates and overreliance on visual representations, served as productive opportunities for learning when addressed through carefully designed tasks and discussions. The findings extend existing frameworks of covariational reasoning and highlight instructional approaches that can support students in developing a robust, quantity-based understanding of concavity.

Enhancement Of A Copolyester’S Impact Resistance Via Inorganic Reinforcement, David Felipe Gonzalez

Electronic Theses and Dissertations 2020 - Present

Thermoplastic copolyester elastomers (TPEEs) are widely used in engineering applications because of their flexibility, toughness, and chemical resistance. However, prolonged exposure to marine environments can reduce their mechanical performance through moisture-induced degradation. This research investigated the use of titanium dioxide (TiO2) nanoparticles and APTES-functionalized TiO2 nanoparticles to improve the mechanical, thermal, and environmental durability of Hytrel 5556. Nanocomposites containing 1 wt.% and 2 wt.% TiO2 were fabricated through melt blending and compression molding. Mechanical properties were evaluated through tensile, compression, flexural, and impact testing, while thermal behavior was characterized using differential scanning calorimetry (DSC). Nanoparticle dispersion was examined using scanning …

Epilepsy-Associated Digenic Variants Affecting An Actin-Mitochondria-Glutamate Pathway Promote Seizure Susceptibility, Shenzhao Lu, Mengqi Ma, Shabab B Hannan, Mingxi Deng, Hu Chen, Zhijian Yu, Lindsey D Goodman, Haein Kim, Yun Zhao, Sandeep Kumar Dubey, Wen-Wen Lin, Xueyang Pan, Debdeep Dutta, Vishnu Anand Cuddapah, Jill A Rosenfeld, Xi Luo, Zhandong Liu, Joshua M Shulman, Hugo J Bellen

Faculty, Staff and Students Publications

Epilepsy affects approximately 50 million people worldwide, yet more than half of individuals with a presumed genetic cause still lack a molecular diagnosis despite the identification of over 1,000 monogenic epilepsy genes. This diagnostic gap is unlikely to be resolved by improved variant detection alone, suggesting that variants affecting the same biological pathway may combine to cause disease. By studying epilepsy-associated actin regulatory genes, we identified a conserved "actin-mitochondria-glutamate (AMG) pathway". We demonstrate that reduced actin polymerization promotes DRP1-mediated mitochondrial fission, increases reactive oxygen species (ROS) levels, and enhances glutamatergic transmission, leading to seizures. The glial innate immune pathway, a …

Technological Advancements Of Hybrid Rocket Engines For Sustainable And Competitive In-Space Propulsion Applications, Ryan J. Thibaudeau, Stephen A. Whitmore, Jared Coen, Joshua Sorenson, Logan Mecham, Ava Wilkey

Mechanical and Aerospace Engineering Student Publications and Presentations

Hybrid rocket engines (HREs), which pair a fluid oxidizer with a solid fuel, offer safety and handling advantages, can reduce environmental impact relative to selected legacy systems, and are capable of deep throttling and restart, making them strong candidates for “green” in-space propulsion applications. However, until very recently, there has not been any flight heritage of an HRE used in a spaceflight mission. Over the past decade, the Propulsion Research Laboratory at Utah State University (PRL-USU) has matured a portfolio of HRE technologies—low-energy arc ignition, digital throttling, additively manufactured sustainable fuels, the Nytrox green oxidizer, and electroplated thruster assemblies—that together …

Dietary Stability Of The Eurasian Beaver Revealed By Hair Stable Isotopes, Linas Balčiauskas, Rasa Vaitkevičiūtė Koklevičienė, Andrius Garbaras, Inga Garbarienė, Laima Balčiauskienė

Turkish Journal of Zoology

The Eurasian beaver (Castor fiber) is a keystone ecosystem engineer whose expanding populations increasingly occupy agricultural landscapes. Hair stable  isotope analysis was applied to reconstruct assimilated diet in 56 legally  hunted beavers in Lithuania in 2024–2025. Stable carbon isotope values were tightly  clustered (–25.53 ± 0.10‰ SE), while those for nitrogen showed greater variability (5.38 ± 0.20‰ SE), indicating limited interindividual dietary differentiation.  Generalized linear models revealed no significant effects of sex, year, or month, and  age-related differences were limited to the youngest individuals. Comparison with  published Polish data showed no significant differences in mean isotope values.  Overall, the results …
