Influence Of Internalizing And Externalizing Traits On Cognitive Performance In Typically Developing Children, Carlie Sivils

Psychology ETDs

This study investigates the relationship between emotional traits—internalizing (INT) and externalizing (EXT) subclinical characteristics—and cognitive performance in typically developing children (TDC). INT and EXT measures from the Strengths and Difficulties Questionnaire (SDQ) and cognitive task performance in various cognitive domains, including in verbal comprehension, perceptual reasoning, memory, and cognitive inhibitory control, using standardized neuropsychological test battery (NIH Toolbox, WASI) were examined. Regression analyses, ordinary least squares and robust regression models, were used to explore associations between INT and EXT traits and cognitive task performance, controlling demographic factors such as gender, socioeconomic status (SES), and ethnicity. Results indicate INT and EXT …

Modelling V-Band Atmospheric Loss With Deep Learning, Ralph Lyndon Gesner

Electrical and Computer Engineering ETDs

Modelling atmospheric loss is fundamental to implementation of future mm-wave terrestrial and earth space communication links. Atmospheric losses have traditionally been estimated by calculating the contributions of individual weather phenomena through in-situ meteorological measurements and statistically derived models for estimating localized atmospheric water content. Collecting data for all points along the propagation path and calculating the physical effects of gases, clouds, and precipitation individually is both time consuming and impractical for large-scale use cases.

In response to these present limitations, this work proposes the use of novel deep learning models for estimating atmospheric losses from tabular meteorological sensor data and …

Simulation Studies Of Mvdc Power Cable For All Electric Aircrafts, Aban Samimi Motlagh

Electrical and Computer Engineering ETDs

MVCD power cable has a vital task in future commercial electric aircraft, which is power delivery. The temperature of the cable during the cable’s operation under low pressure is higher than the atmospheric pressure, which increases the cable losses. In this paper, the temperature and electric field across the insulator of the 5 kV DC Southwire cable is simulated up to 10 hours of cable operation. Furthermore, the temperature of the cable is shown with and without the presence of the chamber box. The other issue of the MVDC power cable is the cable joints and terminations. The electric field …

Operations On Submodules With The Multiplicative And Quotient Properties, Jiekai Pang

Mathematics & Statistics ETDs

Inspired by the works of Petro, Epstein, Vassilev, and Morre, this thesis aims to study the generalized definitions of the semiprime operation, weakly prime operation, and standard closure operation on rings, that is, the multiplicative operation, weakly multiplicative operation, and standardly multiplicative operation on submodules. Then, we will use Matlis duality to induce the dual notions of these definitions on submodules of Matlis-dualizable Artinian modules. In order to understand the dual notion of the standardly multiplicative operation, that is, the standardly quotient operation, we will classify the operations on the injective hull of residue field of the ring K[[x,y]]/(xy) which …

Forest Response To Increasingly Frequent Fire And Drought Disturbances, Kevin G. Willson

Biology ETDs

Changes in fire regimes and drought intensity have increased fire and drought severity in southwestern forests, decreasing forest resilience to recent changes in climate. As tree response and regeneration after disturbance are critical for forest persistence, this dissertation assesses ponderosa pine regeneration patterns after high-severity fire, tree growth response to the reintroduction of frequent-fire, and tree growth response to multiyear droughts in fire-maintained and fire-excluded forests. We found that high-severity patch locations were more likely to regenerate when positioned downwind, downslope, and near intact forest. Trees had similar growth responses to first-entry fires and reburns following long-term fire-exclusion. After experiencing …

Tnf Prevents Establishment Of Anti-Tumor Immunity And Elucidates Toxicities Following Myxoma Virus Based Oncolytic Virotherapy, Miriam Beatriz Valenzuela Cardenas

Biomedical Sciences ETDs

Tumor Necrosis Factor Alpha (TNF) can lead to tumor regression through its direct cytolytic activity, yet it has also been implicated to facilitate tumor progression. This scenario complicates the efficacy and applicability of TNF based therapeutics as treatment for malignancies. In the context of oncolytic virotherapy (OV) which uses replicating viruses to treat tumors and acts by triggering production of pro-inflammatory cytokines, exploring such mechanisms is vital. Here we show that a Myxoma based oncolytic virus (vPD1/IL12) can induce large amounts TNF. The presence of TNF in the context of vPD1/IL12 plays a detrimental role both for tumor regression by …

Source Detection And Automatic Modulation Classification For Modern Antenna Array Processing, Jayakrishnan Vijayamohanan

Electrical and Computer Engineering ETDs

Source detection and automatic modulation classification are two of the most important steps in any array processing task. In this research a novel deep learning model referred to as RadioNet, is proposed that is focused on solving both these problems by reformulating them as a multi-label classification problem. Traditional approaches to both these topics face challenges in scenarios with noise, interference, fewer number of snapshots, and high number of sources. The limitations of the conventional models are investigated and overcome by the proposed solution. RadioNet is also compared with other existing state-of-the-art machine learning based solutions. The introduced model is …

Targeting Myeloid Cell Iron Metabolism In Salmonella-Induced Colitis, Mariella Arcos Padilla

Biomedical Engineering ETDs

Salmonellosis is a severe infection caused by Salmonella enterica serovar Typhimurium, leading to significant global morbidity and mortality.

Previous studies have shown that mice lacking the iron storage protein ferritin heavy chain (FTH1) in myeloid cells exhibit worsened Salmonella infection. Nuclear receptor co-activator 4 (NCOA4) directs FTH1 autophagic degradation to release iron from storage during conditions of low iron. However, the role of myeloid NCOA4 in regulating bacterial infections remains unclear.

Here, we found that myeloid NCOA4 deficiency augments spleen iron levels and increases cellular iron accumulation, oxidative stress, and ferroptosis in bone marrow-derived macrophages (BMDM) cells. This deficiency also …

Modern Agricultural Servitude: The Modern Farm Worker Experience In The Salinas Valley, Jesus E. Tavarez

Chicana and Chicano Studies ETDs

The prevailing narrative in Chicanx studies focuses on the historical labor activism of the United Farm Workers (UFW) in the 1960s and ‘70s. I am particularly interested in examining the contemporary campesino experience in the Salinas Valley by discussing the history behind Mexican cheap labor, low wages, exploitive work conditions with inadequate healthcare, agrochemical exposure, and historical consciousness of farm workers. I will argue that farm workers are in dire need of a migratory reform as an approach to improve the working conditions of farm workers throughout California. This research aims to shed light on how the multi-billion-dollar agribusiness industry …

Evaluation Of Electrode Configurations For (0,2) Piezoelectric Ultrasound Transducers, Abdul Qayoum Popal

Mechanical Engineering ETDs

Piezoelectric micro ultrasound transducers (PMUT array) are pivotal in MEMS applications. They typically operate in the fundamental (0,1) acoustic mode and are not significantly researched for higher modes (0,2) and (0,3). Similarly, vibrating mesh atomizers (VMAs) demand the second (0,2) mode and third mode (0,3) for effective aerosol generation, highlighting the need for optimized electrode configurations—a relatively unexplored area. This study presents the first comprehensive analysis of how electrode designs influence PMUT performance in the (0,2) mode for VMA applications.

Utilizing COMSOL multiphysics finite element modeling (FEM) with residual stress considerations alongside experimental validation, we demonstrate that optimized electrode configurations …

Theory And Algorithms To Learn, Propagate, And Exploit Uncertainty For Stochastic Optimal Control Of Dynamical Systems, Vignesh Sivaramakrishnan

Electrical and Computer Engineering ETDs

Non-Gaussian uncertainty frequently arises in learning and control problems involving stochastic dynamical systems, particularly in autonomous vehicles, UAVs, satellites, and robotics. In this dissertation, we propose a new framework that leverages characteristic functions that provides a frequency-domain representation of random variables. The dissertation is structured into three key areas. First, we address model-based stochastic optimal control for linear systems with non-Gaussian noise, demonstrating that characteristic functions can be used to enforce chance constraints and control systems toward desired distributions. Second, we explore data-driven stochastic control, utilizing empirical characteristic functions to handle systems with unknown disturbances. In addition, we derive several …

The Re-Presentation And Mis-Re-Presentation Of The “Indigenous Woman” Throughout Mexico’S Colonial And Early Independence Periods (1521–1830), Alejandra Daosiri Rodriguez

Art & Art History ETDs

This research examines the visual and textual representations of Indigenous women in colonial New Spain and early independent Mexico (1521–1830), revealing how these images evolved alongside dynamic colonial political, social, and cultural shifts. Through an analysis of codices, portraits, and other material culture, this study demonstrates how colonial authorities, artists, and patrons manipulated these depictions to serve wider colonial agendas, from evangelization to social stratification. These representations often used Indigenous women as symbols, rather than as individual subjects, to reinforce hierarchical colonial structures, shape racial and gender identities, and support efforts to ‘civilize’ the native population. By focusing on pivotal …

Energy Efficiency Optimization In Integrated Sensing And Communication Networks, Arianna M. Santamaria Penafiel

Electrical and Computer Engineering ETDs

In the emerging landscape of Integrated Sensing and Communication (ISAC) networks, achieving energy efficiency while concurrently performing sensing and communication tasks remains challenging. This paper introduces a new framework, a novel solution that empowers User Equipment (UEs) to make informed decisions regarding their transmission power allocation, optimizing the energy efficiency of sensing, communication, and data reporting to the gNB (gNodeB) functions. Initially, a novel ISAC network paradigm is proposed, where the gNB employs rewards, such as monetary incentives, to motivate UEs to engage in sensing, data collection, and reporting within its coverage area based on the principles of Contract Theory. …

Dental Hygiene Programs’ Use Of Oral Health Literacy Techniques For Special Needs Patients And Caregivers, Socorro D. Tejeda Diaz

Dental Hygiene ETDs

This study examined oral health literacy communication techniques in dental hygiene programs across the U.S. for special needs patients and their caregivers. The study surveyed 46 U.S. dental hygiene program directors on communication techniques, degrees offered, and subject areas. Two-sample t-tests compared differences in communication techniques between AAS and BAS and subject areas. Most respondents routinely employed printed materials with 2 or 3 concepts, speak slowly, and simple language. When comparing the variances in communication techniques offered in AAS and BAS, we observed a t-statistic of 2.06 with a corresponding p-value of 0.54. This suggests that the mean communication techniques …

The Social Matter Of Opioids: Glitches In Immunity Beyond The Human, Nathan A. Leach

American Studies ETDs

The Social Matter of Opioids: Glitches in Immunity Beyond the Human examines the contemporary opioid crisis and its relationship to capitalism, imperialism, and biomedicine. This dissertation also considers how the twin processes of crisis and racialization relate to how human-opioid entanglements perform and transgress normative anthropological assumptions of difference. Through theories of biopolitics, Black feminism, queer of color critique, and psychoanalytic insight, I argue for a more critical account of the entanglement of humans with opioids where processes of capitalist and imperial crisis produce novel forms of social ontology. I substantiate this by examining speculative tissue economies, interspecies relationality, draconian …

Rational Design Of Nanoparticles For Overcoming Barriers Of Nucleic Acid Delivery: Applications In Cancer Therapeutics, Angelea M. Maestas-Olguin

Chemical and Biological Engineering ETDs

The use of exogenous nucleic acid technologies to modulate aberrant protein expression resulting from genetic mutations is a promising therapeutic approach for the treatment of diseases such as cancer. The promise of nucleic-based therapeutics is dependent on the development of platforms that effectively protect nucleic acids from nuclease degradation and deliver the nucleic acids to specific intracellular locations (nucleus or cytosol) of target cells. The application of nanotechnology for development of nucleic acid-based nanomedicines is poised to revolutionize the clinical landscape of cancer. In this dissertation, I demonstrated the rational design, synthesis and evaluation of a lipid coated mesoporous silica …

Ready, Set, Woes: A Narrative Inquiry Into Special Education Teacher Attrition By Transfer To General Education, Brent G. Collom

Teacher Education, Educational Leadership & Policy ETDs

Despite the prevalence of unfilled special education teaching positions nationwide, it is fair to ask whether there is truly a shortage of special education teachers (SETs). While SETs leave education at high rates, they are almost twice as likely to transfer to general education positions. Many former SETs are employed in schools yet outside of special education.

This narrative inquiry examined the stories of 10 former SETs who transferred to general education. This study found that former SETs continue to identify as teaching special education. Former SETs want general education teachers (GETs) and administrators to have training in special education …

Partnering with a commercial silicon-germanium epitaxy supplier, we obtained shallow, undoped germanium quantum wells with high-crystalline quality, confirmed through x-ray diffraction, secondary ion mass spectroscopy, high-resolution scanning transmission electron microscopy, and energy dispersive x-ray spectroscopy. Hall bar devices fabricated on single quantum wells revealed that surface preparation can tune transport properties while maintaining peak mobilities around 10⁵ cm²V⁻¹s⁻¹. Manganese-germanide spintronic contacts were integrated via solid-state reaction, with contact quality assessed through Schottky diodes, transfer length …

Hypoxia-Inducible Factor 3Α1'S Role In Promoting Iron Loading, Tumorigenesis, And Metastasis In Colorectal Cancer, Luke B. Villareal

Biomedical Sciences ETDs

The interplay between hypoxia and iron metabolism drives colorectal cancer (CRC) progression. This dissertation investigates hypoxia-inducible factor 3α1 (HIF-3α1), a protein linked to poor CRC outcomes, focusing on its roles in metastasis, epithelial-to-mesenchymal transition (EMT), and iron loading via transferrin receptor (TFRC). HIF-3α1 promotes CRC cell migration by upregulating zinc finger E-box binding homeobox 2 (ZEB2) and suppressing N-myc downstream-regulated gene 1 (NDRG1), while TFRC-mediated iron accumulation supports tumor growth and survival. Iron chelation reduced EMT markers, migration, and tumor growth, highlighting iron's critical role. Additionally, HIF-3α1-induced TFRC expression altered nucleotide synthesis enzymes carbamoyl-phosphate synthetase-aspartate transcarbamoylase-dihydroorotase (CAD) and phosphoribosyl pyrophosphate …

Custom Cathode Optimization For Electropolishing Additively Manufactured 316l Stainless Steel, Kasandra Escarcega Herrera

Mechanical Engineering ETDs

Laser powder bed fusion (LPBF) has become increasingly popular for its ability to rapidly manufacture complex metallic parts. However, the surface properties of as-built LPBF parts may degrade overall performance due to tortuous surface features. Consequently, post-processing like electropolishing (EP) to reduce the surface asperities is often needed for LPBF parts to perform as expected. Utilizing experimental and computational approaches, this project aims to more uniformly EP complex shaped parts made from LPBF 316L. For the experimental approach, parts with a three-dimensional T-shape were printed out of 316L stainless steel and EP using an acidic-based and a polyethylene glycol/NaCl-based electrolyte. …

Validation Of A Culturally Adapted Neuropsychology Screening Measure Among Older American Indians, Katherine A. Edwards

Psychology ETDs

American Indian (AI) older adults are most at risk of developing Alzheimer’s disease and other dementias in the United States. However, there are no cognitive screening tools validated or normed for AI populations, limiting the diagnostic accuracy of current tools. In this study, a culturally adapted screening tool was adapted for three different sites with older AI adults, and validated against widely used neurocognitive screening measures to determine convergent validity. Results found that adapted story memory scores were significantly higher than unadapted scores. Additionally, culturally salient story memory scores were more consistent with measures of crystalized intelligence, while unadapted story …

Language Use Of Emergent Bilingual Latino/A Students In A Music Class Setting, Karen G. Granados Dumais

Language, Literacy, and Sociocultural Studies ETDs

This study investigated the way in which emergent bilingual students utilize their linguistic repertoire in order to achieve new learning. Previous research has suggested that bilingual students learn differently than their monolingual counterparts due to their varying linguistic repertoires. Research has also suggested that translanguaging and culturally relevant teaching are valuable frameworks to adopt in the classroom, as they result in a better academic experience for all students.

I took an ethnographic approach while conducting a case study. I collected data in my elementary music classroom in the form of observations, audio recordings, and document analysis in order to help …

“Mexico Has Spilt American Blood Upon American Soil!” The Role Of The Mexico-U.S. Border In The Promotion Of American Nationalism, 1821-1920, Jon M. Williams Phd

Sociology ETDs

International borders not only serve as the edge of a nation-state's sovereign territory, but they also aid in informing popular conceptions of its national identity. This study examines how the Mexico - U.S. border served as a spark for episodes of American nationalism from 1821-1920. In examining three historical periods whereby the border was forming, disrupted, or challenged, I demonstrate how borders serve as sources, both symbolically and physically for the expressions of American nationalism. I utilize inductive qualitative discourse analysis of American actors embedded along the border, in Mexico, or serving as political leaders, to sample some of the …
