Early transition metal organometallics chemisorbed on extremely Brønsted acidic sulfated metal oxides such as sulfated alumina (AlS) and sulfated zirconia (ZrS) produce highly active single-site catalysts for olefin polymerization, alkene and arene hydrogenation, and alkane hydrogenolysis, typically with a large percentage of catalytically significant sites. The low support conjugate basicity...
Ross (2015) proposed a recovery theorem which uses prices of contingent claims to recover market’s expectations about underlying asset returns. His work relies on two assumptions. He assumes all uncertainty of the economy follows a finite state irreducible Markov chain and that the pricing kernel is transition independent. We first...
Web users suffer from security and privacy threats. According to Symantec, 430 million new unique pieces of malware have been discovered in 2015, and over half a billion personal records were stolen or lost in the same year. Defense mechanisms can be classified as reactive approach and proactive approach. Reactive...
Previous research indicates that regret is a painful experience for people but often leads to enhanced self meaning and personal growth. In this study, we employ a narrative approach to explore the architecture and coping methods of regret experiences in late midlife adults. We relate variation in regret narratives told...
The goal of this project was to better understand the pathogenesis behind rheumatoid arthritis(RA), an autoimmune disorder that primarily affects the joints. Despite affecting around 1.3 million people in the United States, its causes are not well-understood. Previous research at Pope Lab indicated that when compared to the healthy controls,...
In this talk and related activities, I hope to inspire others to take up one of the greatest challenges of our era: narrowing the governance gap which is at the root of many of Africa’s development and security dilemmas. In view of the emergence of many fragile and failed states,...
A critical challenge in improving the quality of life for spinal cord injury survivors is to restore the capacity to grasp and manipulate objects. While progress has been made to restore hand function by using functional electrical stimulation (FES) to activate muscles, providing the means to control the multiple degrees...
This dissertation argues that the National Science Foundation's role in, and influence on, the development of large scale scientific and technological systems, most notably improvements to U.S. information infrastructure, can best be understood through an examination of the NSF's institutional history. Because of the Foundation's weakened starting position at its...
Micro/nanoscale friction behavior has drawn a great deal of attention because it can reveal friction behavior at the interface level and ultimately lead to the discovery of the origin or real mechanism of friction. Surface wettability is an important property of solid surfaces and has been widely used in fundamental...
