Nature often uses reaction-diffusion(RD) as a means of making structures and materials of unique properties or morphologies on scales from macro- (e.g., stripes in zebras, tigers, and seashells, and formations in trees, agates, and rocks) to microscopic (e.g., cellular growth, chemotaxis and biological waves). However, reaction-diffusion phenomena have not yet...
This dissertation studies two long-standing asset pricing anomalies: "Value and Growth Effects" and "Momentum Effects" via the channel of market imperfections. These market imperfections stem from basic information asymmetry problem, and take forms of contracting problems and less than perfectly competitive information intermediaries.
The first essay (joint with Zhi Da)...
Hypoxia is a reduction in the normal level of oxygen tension and occurs during acute and chronic vascular disease, pulmonary disease, and cancer. The key transcription factor that regulates the cellular responses to hypoxia is hypoxia-inducible-factor-1 (HIF-1). Understanding how HIF-1 is regulated is fundamental for understanding the biology of tumor...
The stratigraphic record of the Phanerozoic provides key evidence of temporal changes in the global carbon cycle over the past 560 myr of Earth history. Measurements of carbon concentrations in ancient marine sediment, in conjunction with a chronological framework, provide a means to reconstruct burial flux history and, thus, evaluate...
This thesis comprises three essays addressing theory and evidence on the household response to tax-favored saving incentive schemes, with a particular emphasis on household risk taking. The US tax code and related regulatory institutions offer a variety of incentives to encourage US households to save and participate in risky investment...
Measurements of the ratios of charged kaon decay rates for Ke3/K2pi, Kmu3/K2pi and Kmu3/Ke3 are presented. These measurements are based on charged kaon decays collected in a dedicated run in 2003 by the NA48/2 experiment at CERN. The results obtained are Ke3/K2pi = 0.2470 +- 0.0009 (stat) +- 0.0004 (syst)...
This dissertation examines the nature and development of Protestant ideology in Tudor England. Historians have traditionally seen Tudor Protestants as classic "magisterial" reformers. Unlike "radical reformers," who formed separated sects and rejected the union of church and state, English Protestants are seen as deeply committed to royal authority and the...
A number of new satiric forms -- or emergent genres -- have exploded in popularity almost simultaneously in recent years, all markedly political, all incorporating the real into the mimetic in striking ways, and all straddling the line between satire and serious political dialogue. This dissertation focuses on three of...
During the sixteenth and seventeenth centuries, many images of dwarves, hirsutes, and castrati depict them in the guise of the monstrous, either as jokes of nature or indices of courtly wit. However, there are some Renaissance portraits of physically deformed individuals that transcend these categories. These portraits point to the...
As technology moves into deep submicron and nanoscale era, undesirable trends such as increasing power density, leakage power, and temperature variation within chips have made thermal effects emerge as a major bottleneck in further technology scaling. Thermal effects are no longer considered as just a reliability issue, but it also...
