Statistical Methods For Single Cell Sequencing Data Analysis, Fei Qin

Theses and Dissertations

The recent emergence of single cell sequencing (SCS) technology has provided us with single-cell DNA or RNA sequencing (scDNA/RNA-seq) information to investigate cellular evolutionary relationships. Despite many analysis methods have been developed to infer intra-tumor genetic heterogeneity, cluster cellular subclones, detect genetic mutations, and investigate spatially variable (SV) genes, exploring SCS data remains statistically challenging due to its noisy nature.

To identify subclones with scDNA-seq data, many existing studies use an independent statistical model to detect copy number profile in the first step, followed by classical clustering methods for subclone identification in downstream analyses. However, spurious results might be generated …

Archetypes Revisited: Investigating The Power Of Universals In Soviet And Hollywood Cinema, Iana Guselnikova

Theses and Dissertations

This paper examines the concept of archetypes in Soviet and Hollywood films, drawing perspectives from ancient philosophy and the thought of Carl Jung and post-Jungians. While psychoanalysis provides a valuable framework for understanding the human psyche and the idea of archetypes, it has its limitations and gaps that require further exploration. To address these issues, this paper proposes the adoption of a structuralist approach, with reference to the work of Vladimir Propp on the morphology of the fairy tale. Incorporating Propp's ideas can complement psychoanalytic theory and provide a more comprehensive understanding of the underlying patterns and structures that shape …

Identification Of New Disinfection Byproducts In Drinking Water And Impacts Of Algae, Md. Tareq Aziz

Theses and Dissertations

The disinfection of water has been hailed as one of the most important triumphs for public health in the 20th century. Drinking water treatment plants produce safe drinking water by inactivating microorganisms through the use of disinfectants, including chlorine, chloramine, chlorine dioxide, UV irradiation, and ozone. However, these disinfectants also produce toxic disinfection by-products (DBPs), through reactions with natural organic matter and anthropogenic pollutants, as well as bromide and iodide present in source waters. The presence of bromide and iodide results in the formation of bromo- and iodo-DBPs which are much more toxic than DBPs containing chlorine. DBPs are always …

Modulation Of Eif2Α Signaling And The Integrated Stress Response By Targeted Therapeutic Attenuation Of Pkr Activity Contributes To Protection Of Dyt-Prkra Cells From Apoptosis, Kenneth L. Frederick

Phoneme Stability In Speech Production Of Cognate And Non-Cognate Nouns In A Bilingual With Aphasia, Katherine Vlach

Theses and Dissertations

With the growing bilingual population in the world comes a greater incidence of bilingual aphasia, a communication disorder characterized by expressive or receptive language impairment in one or both of a bilingual speaker’s languages. The cognate facilitation effect, which has greatly been explored in healthy bilingual studies, has shown that cognates are named faster and more accurately than non-cognates; as the cognate facilitation effect is also retained in bilingual speakers with aphasia, it is thought that cognates could potentially be used as a treatment tool to facilitate lexical access, particularly when a bilingual speaker with aphasia presents with one of …

Bayesian Spatial And Spatio-Temporal Models For Complex Data Sets, Rongjie Huang

Theses and Dissertations

The cost of testing for infectious diseases can be high, and analyzing large amounts of historical data to forecast disease prevalence can be a time-consuming process. Group testing techniques offer a way to decrease the expenses associated with testing, but this comes at the cost of increased complexity of the data structure due to grouping and imperfect testing when compared to individual-level testing. In this dissertation research, we propose two Bayesian mixed effects spatial group testing regression models: one for areal data and the other for point process data. The former model utilizes a conditional autoregressive (CAR) prior for areal …
