Molecular Phylogenetics of Diurnal Birds of Prey in the Avian Accipitridae Family.
(2007)
The avian family Accipitridae includes 240 species and 60 genera of hawks, eagles, Old World vultures, kites, accipiters, goshawks and harriers. Phylogeny for Accipitridae has been difficult to resolve with morphological ...
Topological and Category-Theoretic Aspects of Abstract Elementary Classes.
(2009)
We consider the behavior of Galois types in abstract elementary classes (AECs), and introduce several new techniques for use in the analysis of the associated stability spectra. More broadly, we develop novel perspectives ...
The Solar Corona Through Numerical Eyes.
(2008)
The Sun and the Space environment serve as a natural laboratory to study the
physics of ionized gas (plasma) under extreme conditions, which are nearly impossible
to achieve using artificial experiments. Understanding the ...
Nitric Oxide Generating Polymers (NOGPs).
(2007)
Several functional polymers that can catalytically generate nitric oxide (NO) from naturally occurring substrates (S-nitrosothiols; RSNOs) in blood by means of immobilized catalytic sites within the polymers were synthesized ...
Development of Analytical Assays for Detection of Small Molecules Using Aptazymes.
(2007)
Advances in understanding the complexity of cellular mechanisms depend upon methods that can quantify affinity interactions between biological molecules. Additionally, fields such as chemical biology and drug discovery ...
Statistical Methods for Missing Data in Complex Sample Surveys.
(2009)
Missing data are a pervasive problem in large-scale surveys, arising when a sampled unit does not respond to a particular question or to the entire survey. This dissertation addresses two major topics in survey nonresponse: ...
Persistent Effects of Self-Administered Cocaine on Cognitive Function and Brain Dopamine Receptors: The Consequences of Differential Drug Access.
(2007)
Drug addicts exhibit a number of cognitive deficits including deficits in frontocortical function and memory that persist long after the discontinuation of drug use. It is not clear, however, whether the cognitive deficits ...
Understanding the Importance of an Energy Crisis.
(2009)
Human development and energy, in general, and electrical energy, specifically, co-exist seamlessly in high HDI countries where reliability and availability is greater than 99%. In numerous low HDI countries, there is 2-50% ...
General Presentations of Algebras.
(2010)
For any finite dimensional basic associative algebra, we study the presentation spaces and their relation to the representation spaces. We prove two propositions about a general presentation, one on its subrepresentations ...
Flat Forms in Banach Spaces.
(2009)
We define a flat partial differential form in a Banach space and show that the space of these forms is isometrically the dual space of the space of flat chains as defined by Adams. These flat partial differential forms ...
