Evaluating Large Language Models For Requirements Engineering And Verification: A Comparative Analysis Of Gpt-5 And Gemini 3 Pro, Guadalupe Nevarez

Open Access Theses & Dissertations

Large Language Models (LLMs) are increasingly viewed as viable tools for Systems Engineering, yet empirical data regarding their effectiveness in generating engineering-quality requirements remains limited. This thesis compares the performance of GPT-5 and Gemini 3 Pro in generating system functional requirements for the Miner Guardian Drone, a prototype UAV designed for minefield remediation. Both models were provided with identical prompts and tasked with producing 15 functional requirements. Two independent raters evaluated the outputs using a nine-dimensional quality rubric aligned with IEEE 29148 and INCOSE guidelines to ensure rigorous assessment. The difference between the models was analyzed using descriptive statistics and …

Expression And Purification Of Prohibitin Proteins And Investigation Of Their Interaction With Mycobacterium Tuberculosis’S Virulence Factors, Zeina Rhaim

Open Access Theses & Dissertations

Prohibitin (PHB) is a highly conserved mitochondrial protein involved in cell cycle regulation, apoptosis, mitochondrial integrity, macrophage activation, cytokine production and many other critical cell functions. The prohibitin complex, formed by Prohibitin-1 (PHB1) and Prohibitin-2 (PHB2), functions as a mitochondrial membrane-associated receptor. Cancer, neurodegenerative disorders, and renal conditions were found to be linked to an irregular PHB expression. Emerging evidence has also highlighted a significant role for PHB in tuberculosis (TB), particularly through its interactions with Mycobacterium tuberculosis (Mtb) virulence determinants. The molecular mechanisms by which PHB influences TB pathogenesis remain poorly understood. Our preliminary studies showed that PHB1 was …

Development And Optimization Of A Deep Level Transient Spectroscopy System, Samuel Ruiz

Open Access Theses & Dissertations

Deep-level transient spectroscopy (DLTS) remains one of the most widely used techniques for identifying electrically active defects that affect leakage current, carrier lifetime, and overall reliability in semiconductor devices. Legacy boxcar or capacitance meter implementations, however, often struggle with limited signal-to-noise ratio, labor-intensive data collection, and poor adaptability across diverse material systems. This thesis presents the design and optimization of a semi-automated, lock-in-amplifier-based DLTS platform. By pairing a Zurich HF2LI with PID-controlled cryogenic sweeps, precision signal generation, and MATLAB driven acquisition and processing scripts, the system will (i) enhance SNR through phase-sensitive detection, programmable low pass filtering, and parasitics calibration; …

Hubert-Based Models And Evaluation Strategies For Pragmatically-Faithful Speech To Speech Translation, Javier Vazquez

Open Access Theses & Dissertations

Pragmatic fidelity in speech-to-speech translation (S2ST) has largely been understudied, leading to communication tools inadequate to support non-superficial dialog. We aim to improve pragmatic faithfulness in English-Spanish translation through the development of machine learning models that are able to predict a corresponding pragmatic representation in the other language. To evaluate performance, we developed a pipeline that utilizes a recently-developed pragmatic similarity evaluation metric to compare models. Further, we developed models that exploit HuBERT features as these have been found suitable for various prosody and pragmatics related tasks. Our models outperformed human and state-of-the-art predictions, albeit the methodology being limited to …

Voices At The Intersection: A Listening Guide Analysis Of Campus-Based Advocates Navigating Institutional Policies On Sexual Violence, Arely Zaragoza-Hernandez

Open Access Theses & Dissertations

Campus-based advocates occupy a critical yet complex position within higher education institutions (Nightingale, 2023; Wood et al., 2021), serving as frontline support for students while simultaneously navigating the mandates, policies, and bureaucratic structures that define their roles. This research study explores the lived experiences of advocates working in university settings, focusing on how institutional mandates from compliance requirements to administrative expectations shape, constrain, and sometimes empower their daily practices. Using a qualitative, phenomenological approach, the study centers the voices of campus-based advocates in Texas to illuminate the tensions between their professional commitments to student-centered care and the institutional imperatives of …

KRASG12C inhibitors (G12Ci) have produced encouraging, albeit modest and transient, clinical benefit in pancreatic ductal adenocarcinoma (PDAC). Identifying and targeting resistance mechanisms to G12Ci treatment is therefore crucial. To better understand the function of KRASG12C and possible G12Ci bypass mechanisms, we developed an autochthonous KRASG12C-driven PDAC model. Compared to the classical KRASG12D PDAC model, the G12C model exhibits slower tumor growth, yet similar histopathological and molecular features. Aligned with clinical experience, G12Ci treatment of KRASG12C tumors produced modest impact despite stimulating a ‘hot’ tumor immune microenvironment. Immunoprofiling revealed that CD24, a ‘don’t eat me’ signal, is significantly upregulated on cancer …

Fecal Microbiota Transplant (FMT) is a treatment for recurrent Clostridium difficile infections and is being explored for other clinical applications, from alleviating digestive and neurological disorders, to restoring microbiomes impacted by cancer treatment. Quantifying the extent of engraftment following an FMT is important in understanding a recipient's response to treatment. Engraftment and clinical response need to be investigated independently to evaluate an FMT's role (or lack thereof) in achieving a clinical response. Standardized bioinformatics methodologies for quantifying engraftment extent would not only improve assessment and understanding of FMT outcomes, but also facilitate comparison of FMT results and protocols across studies. …

SARS-CoV-2 is the betacoronavirus causing the COVID-19 pandemic. Although the SARS-CoV-2 genome and transcriptome were reported previously, the function of individual viral proteins is largely unknown. Utilizing biochemical and molecular biology methods, we identified that four SARS-CoV-2 RNA-binding proteins (RBPs) regulate the host RNA metabolism by direct interaction with mature miRNA let-7b revealed by Nuclear Magnetic Resonance spectroscopy (NMR). SARS-CoV-2 RBP Nsp9 primarily binds mature miRNA let-7b, a direct ligand of the Toll-like Receptor 7 (TLR7), one of the potential SARS-CoV-2 therapeutics. Nsp9 suppresses host gene expression possibly by promoting let-7b-mediated silencing of a cellular RNA polymerase, POLR2D. In addition, …

Automated Design Of Scaffold-Free Dna Wireframe Nanostructures, Wen Wang, Abdulmelik Mohammed, Rong Chen, Antti Elonen, Silian Chen, Mengfan Tian, Junhao Yang, Ye Xiang, Pekka Orponen, Bryan Wei

Faculty Research, Scholarly, and Creative Activity

Computer-aided design has become common practice in DNA nanotechnology, and many programs are available that make the sophisticated design processes accessible to both the core research community and curious scientists in other fields. However, most of the design tools are committed to the scaffolded DNA origami method. Here we present an automated design pipeline for creating DNA wireframe nanostructures based on a scaffold-free molecular self-assembly approach. Unlike in the DNA origami method, scaffold-free designs are not built around a global backbone strand but are constituted entirely of short, locally intertwined oligonucleotides. This overcomes many limitations inherent in scaffolded nanostructure designs, …

Of Birds And Beef: Expanding The Knowledge Of Rotational Grazing Systems On Grassland Bird Productivity In North Dakota, Taylor James Linder

Theses and Dissertations

Cattle grazing is one of the main economic contributors driving grassland ecosystem existence across the landscape. Cattle grazing can impact a variety of aspects of grassland ecosystems functions, including which wildlife species use them and in what ways. Given the drastic declines in grassland passerines, it is especially important to understand how different grazing practices affect critical population metrics such as reproductive success, clutch size, and number of fledglings. There is a wealth of research on grassland passerine reproductive in response to grazing systems throughout North America; however, most of the existing literature studies more traditional, longer rotational (LR) grazing …

Research outputs 2022 to 2026

Seagrass meadows play a key role in the global carbon cycle through storing carbon in their biomass and soils. However, the lack of global assessments of carbon stocks in seagrass biomass and net primary production (NPP) limits our understanding of their role in the carbon cycle. Here, we provide global estimates of biomass carbon stocks and NPP encompassing seagrasses with different life-history strategies, across bioregions and 66 countries. Seagrass meadows show up to 800-fold differences in biomass across different life-history strategies and bioregions (mean ± SE; 1551 ± 40 kg C ha⁻¹), whereas seagrass NPP (5833 ± 557 …

Research outputs 2022 to 2026

Individuals are increasingly using artificial intelligence chatbots, such as ChatGPT, to seek conversational support for their personal mental health difficulties. Heightened concerns about mental health stigma may make anonymous, on-demand chatbot interactions more appealing for some than traditional face-to-face support. This study examined if using ChatGPT-4 for personal mental health difficulties is associated with two distinct forms of stigma, anticipated stigma and self-stigma. Our main aim was to investigate if the perceived effectiveness of ChatGPT use for mental health issues mediates the relationship between ChatGPT usage and anticipated stigma and self-stigma. The sample comprised 73 participants, mostly undergraduate psychology students. …

Soil Organic Carbon Depth Profiles And Centennial And Millennial Decay Rates In Tidal Marsh, Mangrove And Seagrass Blue Carbon Ecosystems, Nerea Piñeiro-Juncal, Miguel Ángel Mateo, Carmen Leiva-Dueñas, Eduard Serrano, Karina Inostroza, Montserrat Soler, Eugenia T. Apostolaki, Paul Lavery, Carlos M. Duarte, Anna Lafratta, Oscar Serrano

Research outputs 2022 to 2026

The management of coastal blue carbon ecosystems can contribute to mitigate anthropogenic greenhouse gas emissions. However, limited information on soil organic carbon (OC) decay rates in tidal marsh, mangrove, and seagrass soils hinders their inclusion in climate strategies and carbon-crediting schemes. Here, we analyzed downcore OC trends in 3761 soil cores from blue carbon ecosystems worldwide. A decrease in OC content with soil depth was measured in 63% of the cores, whereas stable and increasing trends were observed in 22% and 15% of the cores, respectively. Based on 85 profiles where OC decay could be modelled, the OC decay rate …

Tectonic Modulation Of Caldera Volcanism On The South Aegean Island Arc, A Metcalfe, Tim Druitt, Katharina Pank, Steffen Kutterolf, Jonas Preine, Sarah Beethe, Axel K.

Many highly hazardous, caldera-forming explosive eruptions occur in extensional tectonic regimes, but the role of lithospheric rifting in modulating caldera volcanism remains enigmatic. IODP Expedition 398 deep-drilled the volcano-sedimentary infills of submarine half-grabens around Santorini caldera on the continental South Aegean Volcanic Arc. Here we use the volcanic tephra archives to produce a high-resolution eruptive chronostratigraphy for Santorini, to ground-truth seismic stratigraphy, and to extract an integrated timeline of volcano-tectonic couplings. The rift basins contain several submarine volcaniclastic megabeds from the caldera-forming eruptions of Santorini and one from the Kos caldera. The thickest megabed succession is < 250,000 yrs old and lies on a seismic reflection onlap surface that records a phase of rapid rifting. Sedimentation lagged behind subsidence during this rifting phase, creating bathymetric troughs. Integrating submarine core-seismic and onland datasets, we propose that rifting may have driven the transition of Santorini from a prolonged state of effusive and minor explosive activity (∼550 – 250 ka) typical of arc stratovolcanoes to one of repeated caldera-forming eruptions (<250 ka). Rapid rifting may have amplified the normal internal dynamics of the magmatic system in three ways, driving the volcano into a sustained, highly explosive state: (1) an increase in the supply of mantle-derived basalt, (2) enhanced shearing, permeability, and melt percolation in the transcrustal magmatic system, and (3) the development of horizontally extensive magma reservoirs. Broadly simultaneous transitions into caldera-forming activity of the widely separated Santorini and Kos Volcanoes suggest that the two magmatic systems are linked by plate-scale lithospheric stresses.

Circadian Rhythms And Neuroendocrine Dysregulation In Adhd: Therapeutic Insights From Omega-3 Fatty Acids, Ayesha Zafar Iqbal, Patricia Marest Suwindi, Sunny Yin-Shan Chen, Lindsay Liang-Tien Cho, Kuan-Pin Su, Jane Pei-Chen Chang

BioMedicine

Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental condition often accompanied by circadian rhythm disturbances, particularly delayed sleep phase. These involve superchiasmatic nucleus (SCN) dysregulation, altered melatonin secretion, and hypothalamic–pituitary–adrenal (HPA) axis activity, which may be exacerbated by artificial light exposure. Genetic studies further implicate circadian mechanisms, linking ADHD with polymorphisms in clock genes such as PER and CLOCK.

Nutraceuticals, particularly omega-3 polyunsaturated fatty acids (n-3 PUFAs), have been proposed as modulators of circadian rhythms. N-3 PUFAs are essential for brain health and may influence melatonin synthesis and sleep–wake regulation. Preclinical and clinical findings suggest that supplementation can improve cognitive …

Ontological Inquiry: A Foundation For Intercultural Communication Competence For Peace, Maria Stergiou

Turning Toward Being: The Journal of Ontological Inquiry in Education

Beyond what we have discovered through research and what we claim to know about learning and teaching intercultural global competencies, I advocate for the inclusion of a pedagogy of ontological inquiry. Informed by my work as the International Cooperation Advisor for Higher Education at the Swiss Agency for Exchange and Cooperation, as well as my lived experience with ontological inquiry for more than 25 years, here I illuminate the access an ontological pedagogy provides to the realization of interculturalcommunication competencies as a foundation for peace.

One Individual’S Culmination Is Another’S Abyss: The Matter Of Mattering, Lou Agosta

Turning Toward Being: The Journal of Ontological Inquiry in Education

One individual’s culmination is another’s new beginning and yet another’s abyss. The abyss is nihilism. The challenge of such a Big Idea as The Culmination (the event, not the title of Robert Pippin’s book) is to weave the hermeneutic tapestry of the meaning of Being (Sein) as disclosed in poetry, aesthetics, and the life-world, while coaxing the lumbering Hegelian camel of German Idealism through the eye of the narrow needle of Dasein’s (Heideggerian) finitude. The world and entanglement are disclosed in a nondiscursive (preconceptual) manner as mattering. The way forward in philosophy lies through innovations in “mattering”—not a conceptual sense …

Music Post-Westernism: From Tonal And Post-Tonal Hegemony To Multipolar Decolonization, Mark Jericho Y. Pacia

Social Transformations Journal of the Global South

Post-Westernism is a transformation in which the West is no longer the hegemonic center but rather projects a new era of music. This research proposes Post-Westernism as the fundamental shift after the post-tonal (contemporary) era in art (classical) music. While the post-tonal era emerged from the rebellion toward tonality, Post-Westernism calls for critiquing the Western nature of both tonality and post-tonality. Through this, Post Westernism investigates the current musical hegemony and proposes a multipolar system via the decolonization and transculturation of music and scholarship. It answers the question: How will composers innovate when innovation is institutionalized and the avant-garde is …

The Two Hungers: Food Security, Morality, And Cash Transfer Policies For Canela Apanjekra People In Indigenous Central Brazil, Bruno Nogueira Guimarães

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article examines how the Canela Apanjekra (Porquinhos Indigenous Land, Maranhão, Brazil) engage with conditional cash transfer policies aimed at combating hunger—especially the Bolsa Família Program—and how these policies are interpreted through Indigenous moral economy. Drawing on long-term ethnographic research (2011–2019) and a household survey conducted in 2019, it argues that “hunger” is not a unitary condition measurable solely through individual consumption, but a relational and ecological experience shaped by obligations to share, by shame/respect (paham), and by shifting conditions of subsistence. The analysis develops the notion of “two hungers”: in the village, hunger is commonly articulated as …
