The III-Nitride material system has already proven to be commercially viable for blue light emitting diodes (LEDs), blue laser diodes (LDs), and near UV photodetectors. Continued interest in this field has driven the desire for even lower emission and detection cut-off wavelengths into the solar-blind / deep UV portion of...
In the first part of the dissertation, I investigate the nature of retail coupons, a popular tool for non-price competition. The widely expressed view that coupons are primarily a tool to allow price discrimination has received mixed empirical supports. I depart from the static framework of the price discrimination theory...
Chagas heart disease, caused by infection with the protozoan parasite Trypanosoma cruzi, is still regarded as a major public health problem in Central and South America. The finding of cardiac specific autoimmunity during infection in both humans and experimental animals has provided a basis for investigation of its potential role...
The nonlinear optical technique, second harmonic generation (SHG), is applied here for the first time to probe single and double strand DNA (ssDNA and dsDNA) chemically attached to fused quartz/water interfaces. DNA interfaces are often a critical functional component of biodetection, thus, the development of molecular biosensors requires a thorough...
On 6 February 2007, President Bush announced that the United States would
create a new military command for Africa, to be known as Africa Command or Africom.
Throughout the Cold War and for more than a decade afterwards, the U.S. did not have a
military command for Africa; instead, U.S....
Bitcoin is a decentralized payment system proposed in 2008 by Nakamoto, who remains anonymous to date. It offers an effective alternative to fiat money or centralized payment systems with advantages on privacy, anonymity, and low international remittance fees. The transactions in Bitcoin payment system are sent through a peer-to-peer network,...
Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting approximately 1 in 10 reproductive-age women and remains the leading cause of female factor infertility among women of childbearing age. PCOS presents with features of hyperandrogenism, irregular menses and polycystic ovaries. Twin and family studies have demonstrated high heritability estimates...
Inflammasomes are signaling complexes that link the recognition of pathogen and danger associated molecular patterns (PAMPs and DAMPs) by cytosolic pattern-recognition receptors (PPRs) to the activation of Caspase-1, leading to the release of the pro-inflammatory cytokines interleukin (IL)-1 and IL-18, and the induction of pyroptosis. In addition to the canonical...
Coronary magnetic resonance angiography (MRA) is emerging as a promising method for noninvasive diagnosis of coronary artery diseases. Nonetheless, acquisition of large-coverage high-resolution coronary artery images requires free-breathing acquisition. Accurately measuring and correcting respiratory motion has been one of the major challenges to coronary MRA. Diaphragmatic navigator (NAV), the current...
This paper examines the current state of Turkish-U.S. relations. While many have noted a chill in the relationship between the two countries, Finn suggests that recent tension has a longer historical background. Rather than a recent development, Finn suggests that Turkish-U.S. relations have seen periods of tension before over the...
