Three-Dimensional Medical Image Registration With Applications In Proton Therapy, Rui Liao

McKelvey School of Engineering Graduate Student Theses & Dissertations

Three-dimensional deformable image registration (DIR) is an important technique in medical imaging, facilitating the alignment of images acquired from different sources or at different times for clinical diagnosis and treatment planning. In clinical proton therapy dose planning, dual-energy computed tomography (DECT) has notably improved the accuracy of estimating the stopping-power ratio map, reducing proton beam range uncertainty. To address the inter-scan motion artifacts inherent in sequential DECT acquisition, we propose a novel motion-compensation scheme to incorporate a three-dimensional DIR method into the joint statistical iterative DECT reconstruction algorithm. We successfully demonstrate that inter-scan motion corrections can be integrated into the …

Paley, Nicole Linskey, Ryan Agnew, Paulo Henrique Arantes De Faria, Annie Feng, Sophia Y. Li, Elisha D. O. Roberson, Philip A. Ruzycki, Ekaterina Esaulova, Jennifer Laurent, Lacey Feigl-Lenzen, Luke E. Springer, Chang Liu, Wayne M. Yokoyama, Et Al.

2020-Current year OA Pubs

HLA-B*27 was one of the first HLA alleles associated with an autoimmune disease, i.e., axial spondyloarthritis (axSpA) and acute anterior uveitis (B27AAU), which cause joint and eye inflammation, respectively. Gastrointestinal inflammation has been suggested as a trigger of axSpA. We recently identified a bacterial peptide (YeiH) that can be presented by HLA-B*27 to expanded public T cell receptors in the joint in axSpA and the eye in B27AAU. While YeiH is present in enteric microbiota and pathogens, additional evidence that pathogenic T cells in HLA-B*27-associated autoimmunity may have had a prior antigenic encounter within the gastrointestinal tract remains lacking. Here, …

Seed Dispersal By Martu Peoples Promotes The Distribution Of Native Plants In Arid Australia, Rebecca Bliege Bird, Douglas Bird, Christopher T. Martine, Chloe Mcguire, Leanne Greenwood, Desmond Taylor, Tanisha M. Williams, Peter M. Veth

Faculty Journal Articles

Commensal relationships between wild plants and their dispersers play a key ecological and evolutionary role in community structure and function. While non-human dispersers are often considered critical to plant recruitment, human dispersers have received much less attention, especially when it comes to non-domesticated plants. Australia, as a continent historically characterized by economies reliant on non-domesticated plants, is thus a key system for exploring the ecological role of people as seed dispersers in the absence of agriculture. Here, we utilize a controlled observation research design, employing ecological surveys and ethnographic observations to examine how seed dispersal and landscape burning by Martu …

Host-Microbiome Interactions In The Teleost Brain, Amir Mani Varnoosfaderani

Biology ETDs

This dissertation investigates host-microbial interactions within the teleost brain, previously considered sterile. Reviewing current literature highlights significant gaps in understanding teleost brain immunity, despite prevalent neurotropic diseases. We mapped the immune profiles of rainbow trout brains and meninges, revealing the olfactory bulbs as the immune effector part of the brain and the optic tectum as a nod2 expression hub. High il6 and il10 levels were noted in the telencephalon. A persistent bacterial community within healthy salmonid brains shares diversity with gut and blood microbiota. Brain bacterial isolates exhibit genomic signatures for brain colonization and polyamine biosynthesis. The microbiota shifts across …

Revisiting The Preparation And Catalytic Performance Of A Phosphine-Modified Co(Ii) Hydroformylation Precatalyst, David R. Holzknecht, Alexandra K. Van Alstine, Brandon P. Russell, David J. Vinyard, Fabrizio Donnarumma, Matthew B. Chambers

Faculty Publications

In light of recent conflicting reports regarding the hydroformylation catalytic activity derived from cationic Co(II) precatalysts of the form [Co(acac)(bis(phosphine))]BF4, the synthetic procedures and characterization of [Co(acac)(dppBz)]BF4, 1, are evaluated. Leveraging calibrated ESI-TOF MS methodologies, substantial quantities of Co(acac)2(dppBz), 2, were observed within samples of 1. The source of the impurity, 2, is determined to derive from incomplete protonolysis of the Co(acac)2 precursor and ligand scrambling occurring during the synthesis of 1. Revised synthetic procedures using lower temperature conditions and longer reaction times afford analytically pure samples of 1 based on ESI-TOF MS and NMR spectroscopic analysis. Complex 1 is …

A Review Of Optimal Procedures For Combining P-Values With A Proposal Of A Bayesian Approach To Identify Auxiliary Covariates, Tiffany Geistkemper

Electronic Theses and Dissertations Archive

In this thesis, we review a meta-analytic procedure for evaluating tests from several studies based on the combination of P -values. We provide a summary of properties of several well-known methods that combine P-values of continuous and independent test statistics. We note that it is not uncommon that, in the process of performing statistical tests, potentially important covariates are sometimes inadvertently not accounted for in the individual studies. We outline a procedure based on a Bayesian regression approach that introduces latent variables that may be used to account for and evaluate the significance of such covariates.

Linguistic Features In Mild And Moderate Dementia, Alexsandra Murphy

Electronic Theses and Dissertations Archive

The aim of this study is to understand what linguistic measures differ in individuals who have dementia versus a healthy control group as linguistic measures can provide insight to discrepancies in cognitive abilities, notably language. The problem with identifying and diagnosing diseases related to memory, such as dementia and Alzheimer’s disease, is that diagnoses require involved medical examinations, such as neuroimaging, and descriptive diagnostics that may be subjective and relative. This can lead to ambiguous results and lack of clarity for patients and their families and medical care team, making it difficult to chart a course of action or make …

Automatic Domain Model Extraction For Introductory Computer Programming, Rabin Banjade

Electronic Theses and Dissertations Archive

This dissertation addresses the difficulties of creating domain models for Intelligent Tutoring Systems (ITS) in computer programming. One significant challenge of designing ITS for computer programming involves determining the essential knowledge components a student must learn to become proficient in programming. One possible solution is to engage programming experts, which is impractical due to scalability and cost constraints. Existing approaches for automatically extracting domain models for computer programming focus on parsing code examples, but their scope is limited. While they can extract some domain terms, they do not adequately address the pedagogical requirements. We address the challenges of automatically extracting …

Predation Of Appendicularians On Prochlorococcus, Carey Sweeney

Dissertations and Theses

Prochlorococcus is the most abundant photosynthetic cell on Earth. This picocyanobacterium is critical to primary productivity and biogeochemical cycles of the open ocean. While abiotic environmental factors that influence Prochlorococcus are relatively well-understood, biotic controls are less well known. Appendicularians are ubiquitous gelatinous zooplankton that feed on marine microorganisms including Prochlorococcus. However, the details of this feeding interaction are extremely understudied relative to its potential importance. In this study, I characterized the relationship between appendicularians and Prochlorococcus with laboratory experiments. I showed that feeding on Prochlorococcus changes with the life stage of the appendicularians and concentration of prey. I …

Crown Shy, Laura Francesca Kincaid

Dissertations and Theses

Crown Shy explores the ripple effects of inheritance--somatic, psychological, and material--and how such inheritance constellates into our adult relations and relating. In three parts, the text undermines nuclear family imaginings, first by pulling them out by the root, and later through radical practice, formal constraint, and syntactic ambiguity. By studying the natural world--the organizing principles of trees, insects, and flowers--Crown Shy attempts to glean strategy from evidence of what is already thriving. Reluctantly lyrical, the text quietly deplores the ramifications of commercial agriculture, including the speaker’s own family farm and ancestral homestead. With the weight of this origin point, …
