Improvement Of Hanford Waste Vitrification Algorithms With Machine Learning, Uncertainty Quantification, And Gradient-Based Optimization, Lagrande L. Gunnell

Theses and Dissertations

Over 200 million liters of nuclear waste is stored in tank farms in Hanford, Washington, USA. An ongoing effort to immobilize non-solid nuclear waste is through waste vitrification, where waste is mixed and melted with glass-forming chemicals (GFCs) to form a waste glass. Algorithms to determine the ideal mixing recipes are formalized as constrained optimization problems to maximize waste loading in the glass product, with constraints on several properties of the glass melt and final product. These properties are on the glass melt, such as viscosity, electrical conductivity, and corrosion rates, as well as the final glass product, such as …

Insights Into Cortical Organization And Executive Dysfunction In Pediatric Traumatic Brain Injury, Madeleine Reading

Theses and Dissertations

Cortical gyrification is essential for cognitive development, yet its relationship with executive functioning (EF) in pediatric traumatic brain injury (TBI) remains unclear. This study examined whether children with TBI exhibit atypical cortical folding in EF-related regions and whether these differences relate to EF performance. Using FreeSurfer 7.1.1, we analyzed local gyrification index (LGI) in 206 participants (ages 5-18) from 14 sites within the ENIGMA Pediatric msTBI Working Group. Vertex-wise regression revealed that longer time since injury (TSI) was associated with increased gyrification in the right fusiform gyrus and multiple left-hemisphere regions, suggesting region-specific neuroplasticity. Contrary to expectations, higher GCS scores …

Epic Fantasy As A Postsecular Genre: The Stormlight Archive's Approach To Religion And Belief, Liz Busby

Theses and Dissertations

Epic fantasy as a genre has often been neglected due to its perceived conservative roots that clash with critical reading practices. This paper proposes that a postsecular lens may be more suitable to the critical study of epic fantasy and examines perhaps the most popular contemporary epic fantasy, Brandon Sanderson's Stormlight Archive, through a postsecular lens, First, the paper examines how the Stormlight Archive combines the premodern, fantastical worldview with modern and post-modern concerns to reinvigorate its exploration of the religious "big questions" through a renewed focus on the spiritual nature of the individual. Next, it examines how Sanderson presents …

The Conditioning Of Reservoir Computing And Ng-Rc For Forecasting And The Effects Of Temporal Overparameterization, Daniel Jensen

Theses and Dissertations

Reservoir computing and "Next-generation reservoir computing" built on nonlinear vector autoregression are algorithms for predicting time series given past observations. Both algorithms have been successful in predicting some chaotic dynamical systems, but this success is not theoretically well understood. This paper considers the conditioning of both algorithms and the nature of the solutions found. With either algorithm, the least squares problem which is solved to give parameters as a function of the time series data is ill-conditioned, leading to parameter non-identifiability. Both algorithms fall into the class of "sloppy models." Standard practice to regularize either algorithm includes a bias towards …

Surface-Texture Fabrication Of Zirconia-Toughened Alumina Using Focused Ion-Beam Machining, Kameron M. Woodruff

Theses and Dissertations

Focused ion-beam machining (FIBM), a precise form of micro-machining, was tested for feasibility in the manufacturing of microscopic dimples in zirconia-toughened alumina (ZTA), a wear resistant ceramic used in artificial joint replacements. The interaction between the ion-beam and the ceramic was characterized in terms of material removal rate (MRR), surface roughness, and notable irregularities (e.g. pitting, steps at vertical faces). These characteristics were used to design and machine patterns of microscopic dimples for tribological testing. The dimple size and pattern area were limited due to a slow MRR and high cost of milling. No significant difference in the coefficient of …

Sample Preparation And Acquisition Strategies To Improve Accessibility And Proteome Depth In Single-Cell And Low-Input Proteomics, Sara Madisyn Johnston

Theses and Dissertations

Proteins are responsible for important cellular functions and processes including regulation, structural integrity, signaling, transport, and immune functions. Proteomics directly identifies these proteins and enables deeper characterization of the dynamic cellular environment beyond the capabilities of genomics and transcriptomics. Single-cell proteomics further enhances this approach by capturing cellular heterogeneity, which bulk proteomics obscures due to averaging protein expression across large cell populations. Despite significant advances in single-cell proteomics, continued innovation is necessary to increase workflow accessibility and throughput, minimize peptide losses, and achieve comprehensive coverage of the proteome. This dissertation addresses these challenges by developing improved sample preparation methods, two-dimensional …

Exploring The Associations Between Young Adults' Autistic Traits And Parental Differential Treatment, Madelyn Winder Bennett

Theses and Dissertations

The current study sought to identify autistic traits that may elicit parental differential treatment (PDT). Understanding these links are important because numerous studies have shown PDT to have negative implications for healthy development. Participants (recruited via Amazon Mechanical Turk) completed a survey assessing their experiences of parental differential treatment and their own autistic traits using the Autism Quotient (AQ) measure (Baron-Cohen et al., 2001). Participants were young adults ages 18-29 (M age = 25.4; 57% Female, 43% Male; 73% White, n = 739) who resided in the U.S. and had at least one living sibling. Using regression analysis, we examined …

Innovations In Sample Handling Automation To Increase Accessibility Of Sample-Limited Proteomics, Nathaniel Ben Axtell

Theses and Dissertations

Innovation is the vehicle that drives scientific research forward in virtually every field. Advances in genome sequencing propelled the human genome project to completion in 2003 and set the stage for the era of proteomics. Now decades of innovation in liquid chromatography (LC) and mass spectrometry (MS) have improved sensitivity sufficiently to enable single-cell proteomics and other sample-limited studies. Single-cell proteomics reveal patterns of gene expression that are often obscured by bulk-scale proteomics, leading to the identification of new protein biomarker candidates. Sensitive targeted proteomics is the key to successful translation of low-abundance protein assays into clinical applications. With a …

Effects Of Novel Fire Regimes On Plant And Animal Communities, Ryan Pienaar

Theses and Dissertations

Human actions are threatening global biodiversity through changes to ecosystems to which species are not well adapted. One of the main pathways by which humans affect change is through altered disturbance regimes. This includes changes in the size, frequency, and severity of wildfires. The impact of wildfires on native plant and animal communities varies across ecosystems as species in a community have adapted relatively predictable fire patterns over time. Changing fire patterns alters successional dynamics that can favor certain species over others and thus have a negative impact on biodiversity. This dissertation evaluates responses of different plant and animal species …

Porous Hierarchically Ordered Hydrogels Demonstrating Structurally Dependent Mechanical Properties, Elisabeth C. Lloyd, Sujata Dhakal, Shahrouz Amini, Rami Alhasan, Peter Fratzl, Douglas R. Tree, Svetlana Morozova, Robert J. Hickey

Faculty Publications

While hierarchical ordering is a distinctive feature of natural tissues and is directly responsible for their diverse and unique properties, efforts to synthesize biomaterials have primarily focused on using molecular-based approaches with little emphasis on multiscale structure. Here, we report a bottom-up self-assembly process to produce highly porous hydrogel fibers that resemble extracellular matrices both structurally and mechanically. Physically crosslinked nanostructured micelles form the walls of micrometer-sized water-rich pores with preferred orientation along the fiber direction. Low elastic moduli (< 1 kPa), high elasticity (extending by more than 12 times the initial length), non-linear elasticity (e.g., hyperelasticity), and completely reversible extension are derived from unevenly distributed strain between the micrometer-sized pores and the polymer chains, which is reminiscent of cellular solids. Control of the material microstructure and orientation over many orders of magnitude (e.g., nm–μm), while holding the nanostructure constant, reveals how the multiscale structure directly impacts mechanical properties.

Mythology Of Autism: Pop Culture, Rhetoric, And Vaccines, Makenzi Strate

Theses and Dissertations

Myths are stories told to provide an explanation for the unknown, reflect cultural beliefs of populations that hold them, and lack scientific evidence to support these stories. Some myths, such as the myth that vaccines cause autism, are harmful toward the groups that they target. Popularized in 1998 with the publication of the Wakefield study, the myth that vaccines cause autism continues to spread and thrive today. To understand the widespread nature and detriments of belief in harmful myths such as this, I implement mythology rhetoric to examine how celebrity Jenny McCarthy utilizes elements of myth to persuade others to …

Organismal Classification And The Phylogenetic Tree: Improving Its Teaching Using Decision-Based Learning, Melissa Cavan

Theses and Dissertations

For a lot of students, learning biology is like learning a new language. There are new terms and concepts that a lot of new students have never heard of. Evolution is the cornerstone for understanding biology, yet it is one of the more misunderstood topics. In combination with learning new terms and concepts some students come in with preconceived ideas about evolution or misunderstandings about how evolution and the phylogenetic tree work. The research indicates instructors attempting active learning techniques to increase understanding of the phylogenetic tree with mixed results, where there appears to be some improvement but nothing significant. …

Genetic Regulation Of Anthocyanin Biosynthesis In Flower Color In Gilia, Veronica Mosquera

Theses and Dissertations

Gilia was the model species in this research to study the genetic regulation of flower color. I generated an F2 population from a cross of two closely related leafy-stemmed Gilia: G. capitata with blue and G. yorkii with white flowers, to obtain the fertile F1, which was selfed. The F2 population showed a segregation ratio between pigmented versus white flowers 3:1, suggesting a single locus with a major effect on the regulation of flower color. Then, the G. yorkii genome was assembled and annotated to become the reference genome to genotype-by-sequencing (GBS) 189 F2 individuals. The Quantitative Trait Loci (QTL) …
