Crucial to the function of polarized epithelial cells is the generation and maintenance of distinct protein populations at the apical and basolateral domains. Cellular mechanisms sustain this polarity by properly sorting apical and basolateral proteins in both the biosynthetic and postendocytic pathways via sorting signals inherent within the protein. N-glycosylation ha....

Nearly 45% of oral squamous cell carcinomas (OSCC) are characterized by amplification of chromosomal band 11q13, which occurs by breakage-fusion-bridge (BFB) cycle mechanism. The first step in this cycle involves loss of distal 11q. Consequently, critical genes involved in the DNA damage response pathway, MRE11A, ATM, H2AFX and CHEK1 are lost in the step preceding 11q13....

Cardiovascular disease is the leading cause of mortality worldwide, and approximately half of all cardiovascular deaths are attributed specifically to coronary artery disease (CAD). Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) procedures play a prominent role in managing the heavy burden of CAD. The purpose of this dissertation was....

Working with Fredric Jamesons understanding of genre as a formal sedimentation of an ideology, this study investigates the historicity of the detective narrative, what role it plays in bourgeois, capitalist culture, what ways it mediates historical processes, and what knowledge of these processes it preserves. I begin with the problem of the detective narratives origins....

In late 1990s, Gap theories and the LibQual model began to be widely accepted by research libraries in the U.S. Since then, library service evaluation and user satisfaction issues have been discussed in various aspects of both the research and professional literatures of library and information science. Although the research presented herein is concerned with the evalua....

This work is composed of three essays on auction theory. In the first essay, we analyze the optimal auction of multiple non-identical objects when buyers are risk averse. We show that the auction forms that yield the maximum revenue in the risk neutral case are no longer optimal. In particular, selling the goods independently does not maximize the seller's revenue. On t....

Readers of Vasaris Vite will be aware of the lively Renaissance tradition of the artists embedded portrait within commissioned works. We are told of numerous embedded self-portraits, a notion that earlier authors including Alberti, Filippo Villani, and Ghiberti, corroborate. This dissertation argues that the Vite, our most extensive source on the subject, set up ideas a....

As the nations archives, the National Archives and Records Administration (NARA) preserves and provides access to records that document how our government conducts business on behalf of the American peoplepast and present. For the American citizen, NARA provides a form of accountability through the records within its custody which affect the nations collective memory. A....

Although code optimizations have been applied by compilers for over 40 years, much of the research has been devoted to the development of particular optimizations. Certain problems with the application of optimizations have yet to be addressed, including when, where and in what order to apply optimizations to get the most benefit. A number of occurring events demand the....

This dissertation proposes an analysis of representative texts within the category of intellectual nations. The idea of intellectual nations is inscribed in the project of questioning the centrality and canonicity of certain cultural productions that have given legitimacy to the hegemonic idea of nationalism, which helped sustain the PRI regime in Mexico. The dissertati....

Many have used the two-point correlation function to study the clustering of galaxies as a function of their properties, such as luminosity, color, and stellar mass. We explore the technique of `marked' correlations, in which clustering is measured with galaxies weighted by a particular property or `mark'. Marked clustering statistics identify and quantify how galaxy pr....

Experiment 1 studies finite system size effects on temporal energy flux fluctuations in three-dimensional (3D) incompressible turbulence. The measured instantaneous energy flux shows that the turbulent energy transfer proceeds towards small spatial scales on average but frequently reverses direction (backscatter) to travel towards larger scales. The frequency of backsca....
