We estimated site-specific effects on pregnancy outcomes using parametric g-computation.

RESULTS: Compared to uninfected women, we observed the adjusted site-specific prevalence differences (PDs) among women with first-trimester malaria of the following pregnancy outcomes: preterm birth …


Synthesis And Characterization Of Novel Diffusible Signal Factor Analogs For Antibiofilm Properties, Elisabeth Rachel Wiley Dec 2024

Synthesis And Characterization Of Novel Diffusible Signal Factor Analogs For Antibiofilm Properties, Elisabeth Rachel Wiley

Electronic Theses and Dissertations Archive

Biofilms are composed of biomolecules, bacteria, and sometimes fungi and are considered the leading cause of antibiotic resistance. Biofilm formation and dispersion is regulated in part by signaling molecules called diffusible signal factors (DSF) through a process termed quorum sensing. However, the mechanism of action behind quorum sensing remains poorly understood. Chapter 1 focuses on the structure activity relationship (SAR) of DSF. DSF are medium chain fatty acids with an alkene at the C2-C3 carbon position. Tail length, branching, and cis/trans configuration all significantly affect antibiofilm action; these affects are also microbe specific. The chapter concludes with a discussion on …


Revisiting Territorial Sovereignty: Origins, Legitimacy, And Modern Implications, Henan Hu Dec 2024

Revisiting Territorial Sovereignty: Origins, Legitimacy, And Modern Implications, Henan Hu

San Diego International Law Journal

The conventional linkage between territory and sovereignty in international law requires reevaluation, with territorial rights shifting from states to nations. Drawing on Anthony Smith’s theory of historical continuity between pre-modern ethnic communities and modern nations, this article argues that legitimate claims to territory are grounded in the historical consolidation of social, economic, and political ties by ethnic groups to specific lands. It traces the evolution of territorial rights from loosely defined ethnic living areas and fluid state boundaries to the modern conception of national territories under effective control. By distinguishing sovereignty as a construct of the state and territory as …

The Encoding Of Decision Variables In Orbitofrontal Cortex (Ofc) Is Longitudinally Stable And Varies By Cortical Layer, Manning Zhang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Economic choices entail computing the values of different options and then making choice by comparing values. Work in primates and rodents has shown that these mental processes rely on the OFC. Neurophysiology studies identified in OFC distinct groups of neurons encoding the value of individual options, the binary choice outcome, and the chosen value. These variables capture both the input and the output of the decision process, suggesting a decision circuit existing in OFC. A primary challenge for the field is to assess the structure and mechanisms governing this circuit. A first fundamental question is whether the circuit is stable …

Husserl’s method, outlined in Ideas I, provides the steps for its implementation in clinical research. This dissertation explores the application of the transcendental phenomenological method as a foundation for research on perception, with the goal of characterizing phenomenological validity as a proper goal of medical epistemology. …


“Repeat A Little:” Time And Freedom In Deleuze’S Difference And Repetition, Mine Sak Dec 2024

“Repeat A Little:” Time And Freedom In Deleuze’S Difference And Repetition, Mine Sak

Electronic Theses and Dissertations

In this dissertation, I examine Gilles Deleuze’s philosophy of time as presented in Difference and Repetition and use it to construct a concept of freedom, which is notably absent in his work. I argue that Deleuze’s exposition of the three syntheses of time provides significant insights for exploring the ontological possibility and structure of freedom. Through an analysis of his theory of the three syntheses of time, I investigate the meanings of agency, destiny, and choice within Deleuze's framework. I demonstrate that free choice necessitates both involuntary and creative action. Given the apparent tension between freedom and involuntariness, I explore …

Hidden Markov Model For Identifying Local Variants In Human Genomes Using Simulated Data, Scott Mccallum Dec 2024

Hidden Markov Model For Identifying Local Variants In Human Genomes Using Simulated Data, Scott Mccallum

Electronic Theses and Dissertations

Identifying adaptive mutations in genetic data is challenging due to the low frequency of occurrence of such events, and because signatures of selection are intertwined with the footprints of various other evolutionary forces that shape our genomes. Even when a larger region appears to be under selection, genomic sites that are linked to adaptive mutations have similar statistical signals, and thus can obfuscate the identification of the actual adaptive mutation. The new method described here uses a Hidden Markov Model that allows for classification of neutral, linked, and sweep (adaptive mutation) genomic sites. This model is general and can be …
