For many scientific applications, the data set cannot entirely fit in main memory. The data must reside out-of-core, i.e., on parallel disks. For many basic data-movement operations such as permuting, if the programmer does not design efficient...
Does early and sustained experience with two languages in childhood modify how language is processed in the adult bilingual brain? Does extensive exposure to two languages influence language processing in the bilingual brain as compared to...
Many environmental toxicants found in pesticides, herbicides, and industrial solvents are believed to have deleterious effects on development by disrupting hormone-sensitive processes. Xenopus embryos were exposed to commonly encountered endocrine...
This thesis centers around a generalization of the classical discrete Fourier transform. We first present a general diagrammatic approach to the construction of efficient algorithms for computing the Fourier transform of a function on a finite...
This dissertation examines the behavioral and physiological adaptations employed by modern humans to subsist in tropical rainforests. I employ various theoretical and methodological approaches to test hypotheses using empirical data from African...
Let K be the function field over a finite field of odd order, and let H be a definite quaternion algebra over K. If Α is an order of level M in H , we define theta series for each ideal I of Α using the reduced norm on H. Using harmonic analysis...
A 62 kDa (p62) mitotic apparatus-associated protein has been shown to be important for the proper progression of mitosis in sea urchin embryos. The thesis project described here focuses on an immunological and a molecular characterization of p62....

Head Direction (HD) cells are neurons located primarily in the limbic system that fire as a function of directional heading in the horizontal, or yaw, plane in the freely moving animal. Our hypothesis is that the HD signal is the result of two...
The present work examines the cognitive structure of the self-concept. Improving upon established measures of self-complexity (H -statistic), cognitive complexity of the self-concept is measured in terms of the number of self-aspects and the...
Biological conversion of biomass to fuels and chemicals offers recognized benefits. The absence of systematic methodologies for scaling up such conversion is an important issue related to realizing these benefits. This thesis addresses this scale...
In the late 1960s, Ihara began work that led to the Ihara zeta function, a zeta function which is defined on a finite graph. This function is an interesting graph invariant which gives information on expansion properties of the graph. It also...
The central topic of the self has proven a vexing conundrum for philosophers and psychologists alike for centuries. Prior research suggests that the self is a powerful cognitive structure which biases attentional mechanisms in favor of apprehension...
Successfully navigating our social world requires the ability to understand the facial expressions of others. Indeed, facial expressions provide information about the emotions and intentions of others. While some expressions provide clear...

We investigate weak and strong refocusing of light rays in a space-time and related concepts. A strongly causal space-time ( X^ n +1 , g ) is emphstrongly refocusing at x ∈ X if there is a point y ≠ x such that all null-geodesics through y pass...

When a nonnative insect or pathogen becomes established in a forest, outcomes for host trees can range from local or minor effects to regional extirpation. Elevated host mortality is often accompanied by compensatory recruitment by co-occurring...
Oligomers -- Structure -- Mathematical models. Nuclear magnetic resonance spectroscopy.
Medical Term: Nuclear Magnetic Resonance, Biomolecular.
Protein complexes play vital roles in the fundamental processes of life. In particular, homo-oligomers are involved in cell signaling, regulation, and transport. To make detailed studies of these symmetric proteins, they need to be discovered, and...
This thesis investigates the embedding theory of orders in central simple algebras, placing a particular emphasis on the role that the phenomenon known as selectivity plays in the theory. Although the notion of selectivity is completely algebraic,...
Renewable energy sources are becoming increasingly important as sustainable alternatives to fossil fuels. One of these renewable sources, cellulosic biomass, is a relatively inexpensive and abundant resource that can be converted into liquid fuels...
