The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly

Health, Exercise, and Sports Sciences ETDs

Hypoxic environments, resulting from decreased atmospheric partial pressure of oxygen, reduce oxygen availability in the blood and tissues, leading to a mismatch between supply and demand. This elicits several physiological adaptations and may influence bone metabolism. Although evidence suggests that hypoxia can modulate bone remodeling through hypoxia-inducible pathways, findings remain mixed, with most data derived from chronic hypoxic exposures in animal and cell culture models. Exercise, an essential stimulus for bone health, may exacerbate hypoxic stress; however, the skeletal response to acute hypoxic exposure combined with exercise remains unclear. We propose that intermittent exercise in hypoxia may increase negative markers …

Shaping Emergent Competitive And Cooperative Behaviors In Multi-Agent General-Sum Games, Ethan F. Erickson

Honors Projects

Reinforcement learning (RL) algorithms can train agents to solve problems in environments using complex behaviors that are not explicitly programmed, known as emergent behaviors. The goal of our research is to investigate how different RL reward values influence the emergence of competitive and cooperative behaviors in games with teams of multiple agents. Specifically, we focus on general-sum games, in which the sum of gains and losses of each team may be non-zero, allowing situations for agents to mutually benefit or mutually fail. Using Unity’s ML-Agents Toolkit to train agents with RL self-play in bounded 2D environments, we identify high-level behaviors …

Ab Initio Method Development For Electronic Structure Response And Symmetry Quantification, Duc Anh Lai

Chemistry Theses and Dissertations

Electronic structure provides a fundamental framework for understanding molecular properties and reactivity, as it encodes the spatial distribution of electrons and their response to external and internal perturbations. This dissertation develops theoretical and computational frameworks to characterize and manipulate electronic structure through two complementary directions: the response to oriented external electric fields and the quantification of symmetry regulation in electron density.

First, a rigorous theoretical and computational framework is established for treating electric fields with arbitrary orientations relative to molecular structure. The concept of the rotational potential energy surface is introduced to characterize the dependence of molecular energy on field …

Beyond Brain Drain: H-1b Visas, Innovation, And Human Flourishing, Joel Wong

Honors Projects

High-skilled migration has become one of the defining features of the modern global economy, especially in technology, engineering, and research-intensive industries. While public debate surrounding the H-1B visa program often centers on its effects within the United States, less attention has been given to how these migration flows affect the countries from which workers originate. This question is important because many sending countries invest heavily in the education and development of highly skilled workers while also seeking long-term economic growth and innovation. This study examines whether increases in H-1B visa migration are associated with changes in innovation outcomes in major …

Fluid Identities: Using Seattle's Diverse Water Narratives To Shape Cultural Values And Adaptive Conservation Strategies, Brooke J. Vanden Berg

Honors Projects

This paper explores human interactions with the environment in and around Seattle, Washington, following its trajectory from the Vashon glacial episode to its present standing as a city on the frontier of future urban climate resilience. By examining the shift from indigenous stewardship to a twentieth-century settler-led industrial “taming” paradigm, ecological vulnerabilities are considered through the lens of ill-advised hydraulic regrading and the centralization and privatization of water infrastructure and rights. This history is contextualized in the 21st century as climate projections indicate that Seattle's reliance on mountain snowpack, increasing thermal extremes, sea-level rise, and hydraulic instability caused by climate …

Marine Geophysical Studies Of Coupled Tectonic And Sedimentary Processes At Active Plate Boundaries, Sarah R. Rysanek

Earth and Planetary Sciences ETDs

Deep-sea and convergent margin sedimentary systems preserve critical records of tectonic and climatic processes that shape Earth’s surface. This dissertation investigates source-to-sink sediment routing and forearc deformation to better constrain the interplay between sedimentary and tectonic processes, through investigations of a deep-sea fan system, and the forearc geomorphology offshore Nicaragua. In the Gulf of Alaska, we integrate ultra-long-offset and regional multi-channel seismic reflection data, multi-resolution bathymetry, and plate reconstructions to remap the Baranof Fan system. Results show that the fan is larger than previously recognized and constructed by two primary depocenters linked to distinct glacial sediment pathways, with accommodation space …

Constraining Magmatic Processes In The Central American Arc Using Melt Inclusion Vapor Bubble Analysis And Triple Oxygen Isotope Modeling And Exploration Of Volatile Contributions To The Production Of Continual Radio Frequency (Crf) Lightning Events, John M. Hamilton

Earth and Planetary Sciences ETDs

Magmatic volatiles are key to determining the processes happening in the subsurface that we cannot directly sample. Advances in measuring volatile and isotope contents from erupted volcanic samples have given us the ability to understand magmatic processes, mixing components that produce the bulk magma composition and potentially precursors to eruptive hazards, such as lightning.

Through analysis of melt inclusions that sample the melt at depth and triple oxygen isotope quantification of olivine crystals from multiple volcanic edifices, the three following studies display how I have utilized these analytical techniques to help unravel processes happening in the subsurface that lead volcanic …

Impact Of Third Trimester Alcohol Exposure (Ttae) On Oligodendrocyte Development And Behavior In Mice, Estrella Villicana

Biomedical Sciences ETDs

Prenatal alcohol exposure (PAE) during late gestation can cause cognitive, behavioral, and motor impairments associated with fetal alcohol spectrum disorders (FASDs). The third trimester corresponds to a critical period of brain growth and maturation. This study examined the effects of Third Trimester-equivalent Alcohol Exposure (TTAE) on oligodendrocyte development and adult behavior. Neonatal mice were exposed to ethanol or air vapor from postnatal day (P) 4–8. Immunohistochemical analyses were performed at P8 and P30 to assess myelination, apoptosis, and oligodendrocyte lineage progression. TTAE significantly reduced myelin basic protein (MBP) expression at P8, which was recovered by P30, indicating delayed developmental myelination. …

Moving As Mycelium: Dance/Movement Therapy With Nature And Its Potential For Sustainability Transformations: A Literature Review, Abby Polk

Expressive Therapies Theses

Environmental degradation and destruction impact the long-term health and wellbeing of humans and ecosystems alike. Humans require new ways of relating to nature that support sustainable futures for all. This thesis argues that dance/movement therapy (DMT) with nature has the potential to facilitate sustainability transformations and that the embodiment of relationality can support the development of reciprocal human-nature relationships. This literature review is grounded in theories of relationality and reciprocity as conceptualized in various Indigenous knowledge systems and the fields of both sustainability and DMT. Existing research suggests that culturally-responsive, embodied, arts-based practices may increase human-nature connectedness and strengthen reciprocity …

Post-Fire Flood Modeling In Ruidoso, New Mexico: Improving Burn Scar Runoff Predictions, Pramesh Bhaila

Civil Engineering ETDs

Recent large wildfires in New Mexico have demonstrated severe hydrological driven by vegetation loss and the development of hydrophobic soil surfaces. This thesis evaluates the performance of three infiltration models—Curve Number (CN), Linear Constant (LC), and Green–Ampt (GA)— for the watershed impacted by the 2024 South Fork and Salt Fires near Ruidoso, New Mexico. All three models performed comparably during post‑fire simulations, with strong performance in 2024 and notable degradation in 2025, particularly for the CN. Post-fire analyses indicate substantial reductions in infiltration capacity, with CN increasing by 18–24%, LC initial deficit decreasing by 65–77%, effective hydraulic conductivity reduced by …

Evaluation Of Intracavity Electromagnetic Field Probes And Sources: Implications For Shielding Effectiveness, Joseph Anthony Ferreri

Electrical and Computer Engineering ETDs

To measure the electric field in a reverberant cavity, a small, minimally invasive probe is required. Common solutions include electrically small surface mounted monopole antennas, B-dots, and D-dots. To obtain an accurate field measurement with a particular probe, it is necessary to characterize it to compensate for its ability to convert electric field into voltage which requires a gauge factor known as effective height. The characterization process is straight forward in open space on a ground plane but requires more insight when in situ in a reverberant cavity. This work adapts ground plane probe characterization methods for cavity measurements, facilitating …

Alternative Positioning, Navigation, And Timing In Global Navigation Satellite System Denied Environments, Joshua R. Atencio

Electrical and Computer Engineering ETDs

Global Navigation Satellite Systems (GNSS) provide the majority of critical positioning, navigation, and timing (PNT) services for civilian, commercial, and military applications. However, GNSS is vulnerable to service denial from spoofing and jamming from adversaries and environmental obstruction. These vulnerabilities highlight the need for resilient Alternative PNT (APNT) methods. This dissertation investigates APNT frameworks operating in GNSS denied environments. We develop coalition formation and matching theoretic models that allow users APNT services from anchor nodes under resource constraints and in adversarial or emergency conditions. The proposed frameworks optimize positioning accuracy, network utility, and system stability while accounting for geometric dilution …

Calibration Methodology, Diagnostic Performance, And Redesign Of The Current Monitors On The Z Machine At Sandia National Laboratories, Stacie Hernandez

Electrical and Computer Engineering ETDs

A proper evaluation of the current diagnostics fielded in the inner-MITL region of the Z facility in 3D simulation models had not been performed until now. The evaluation of the current monitors has brought insight to their performance in a new view that has led to discoveries. The B-dot probe was the current diagnostic-of-choice since before the refurbishment of the Z facility [1] and until the development of the Inductively Driven Transmission Line (IDTL) current diagnostic [2]. Experimental data has shown that the IDTL can produce cleaner signals and it is more robust than conventional B-dots. Simulation (modeled using COMSOL …

Novel Algorithmic Methods For Random Telegraph Noise Detection And Characterization In Electronic Devices, Victor Darie Pepel

Electrical and Computer Engineering ETDs

Random telegraph noise (RTN) produces discrete stochastic fluctuations in nanoscale semiconductor devices and increasingly limits performance and reliability as dimensions scale. This dissertation introduces three algorithmic contributions enabling automated and accurate RTN characterization across diverse devices and operating conditions. First, a computationally efficient histogram-based detection algorithm enables rapid identification of RTN in large focal plane array datasets for statistically robust defect analysis. Second, a frequency decomposition framework separates slow and fast RTN components, extending the range of extractable time constants and reducing estimation error in multi-trap signals obscured by background noise. Third, to address the lack of standardized RTN metrics, …

Stochastic Derivative-Free Deep Learning Methods For Solving High Dimensional Partial Differential Equations, Qing He Mr.

Mathematics Theses and Dissertations

Solving high-dimensional partial differential equations (PDEs) is a fundamental challenge in scientific computing, with applications ranging from quantum chemistry and computational finance to statistical physics and stochastic optimal control.  Classical numerical methods such as finite element or finite difference schemes suffer from the curse of dimensionality, rendering them computationally infeasible when the dimension $d$ exceeds a handful. Physics-informed neural network (PINN) methods alleviate this by embedding the PDE residual directly into a loss function, but they require computing derivatives of the network with respect to its spatial inputs---an operation that scales poorly in high dimensions and demands that the approximate …

Kinetic Study Of Oil–Water Separation In A Dual Port Inlet Cyclone Separator, Ikhwanul Qiram, Agung Nugroho

Journal of Mechanical Engineering Science and Technology (JMEST)

In this study, a Computational Fluid Dynamics method is used to investigate the oil–water separation kinetics in a dual-port inlet cyclone separator. This was achieved using the Reynolds Stress Model coupled to an Eulerian multiphase framework. Three Reynolds numbers were studied (Re = 1.41×10⁵, 1.94×10⁵ and 2.52×10⁵) to analyse the flow; axial velocity distribution, vortex stability, radial migration velocity and separation efficiency were examined individually. Results indicate that both the radial migration velocity (vᵣ) and separation probability (p_remove) grow with Reynolds number, especially for larger oil droplets (10–100 µm). The best condition concerned is that …
