Understanding how spin waves propagate through ferromagnets is an important component of a wider international effort to create spintronic devices. In this thesis, we develop a propagating spin wave spectroscopy to make a variety of measurements on thin films of Yttrium Iron Garnet (YIG), a material known for having long...
In this dissertation, I cover three different topics in macroeconomics. In Chapter 1, I explore the macroeconomic implications of an increase in business competition and its micro transmission channels. In Chapter 2, I document a rise in savings and cash holdings by non-financial corporations across advanced economies and show that...
The concealed information test (CIT) has garnered more empirical support than other methods of recognition detection and has a firm theoretical foundation. Because it occurs involuntarily, even when recognition is denied, P300 amplitude is a robust indictor of concealed information. Although the P300-based CIT shows great promise for field use,...
The tension-spoke bicycle wheel owes its stiffness and strength to a cooperative relationship between the rim and the spokes: the rim holds the spokes in tension to prevent them from buckling under external loads, while the spokes channel external forces to the hub and prevent the rim from becoming severely...
The structure of the North American crust and mantle was investigated using P wave teleseismic tomography and the links between seismic tomographic models, locations of volcanism, sediment isopachs, and continental scale crustal structures via plate reconstruction modeling. Nearly 50,000 teleseismic P wave delay times were measured from seismograms recorded by...
Infidel(itie)s of Colour: Unruly Black Bodies, Modernity and Performance in Post-Apartheid South Africa focusses on the ways that queer and feminist artists of colour draw upon their traditional black cultural heritage and spiritual practises as a means of laying claim to cultural citizenship and belonging in post-apartheid South Africa. I...
Clustered regularly interspaced short palindromic repeats (CRISPR) and their associated Cas proteins provide an immune-like response in many prokaryotes against extraneous nucleic acids. CRISPR-Cas systems are classified into different classes and types that vary widely in composition, target recognition, and overall mechanism. The main division of CRISPR-Cas systems occurs between...
The focus of this thesis is on evaluating, designing, and applying statistical methods that elucidate molecular mechanisms by seeking to understand the pathways that contribute to disease. Chapter 1 introduces the field and motivates the work in this thesis. Chapters 2, 3, and 4 describe original work. Chapter 5 recapitulates...
The halide perovskites AMX3 (A = large cation, B = Sn or Pb, and X = halide) have been the subject of intense investigation due to their outstanding optical and electronic properties, which have enabled high solar cell efficiencies thanks to a beneficial electronic structure and long charge carrier lifetimes....
Motor planning is fundamental to the performance of everyday reaching movements. The influence of planning is not limited to voluntary movements but extends to involuntary movements initiated in response to sensory stimuli, such as postural perturbations applied to the arm. Stroke alters voluntary reaching and the involuntary response to perturbations,...
