"Random Involutions and the Number of Prime Factors of an Integer"
Uthsav Chitra '17
Mathematics/Statistics
In my project, I tried to approximate d(n), the number of prime factors of an integer n, by comparing the number of fixed points of a random involution on F2g(n) to the number of fixed points of a specific involution, τ(n). I showed that the expected number of fixed points of a random involution converges, so that d(n) cannot be approximated using this method; moreover, I showed that the involution τ(n) is not random, as it has more fixed points than a random involution.
"Blockage of the SDF-1/CXCR4 Pathway to Attenuate Osteoarthritis"
Nathan Thomas '14
Biology/Biomedical Engineering
Looking to confront the lack of chemical agents for osteoarthritis (OA) therapy, this project explores the potential of the small drug, AMD3100 to block a key pathway in OA development. Building on mechanism based research, our hypothesis was tested in an in vivo model of OA, involving the continuous infusion of AMD3100. Results to be discussed include morphological changes, enzymatic changes, and in vivo detection methods.
"Semiconductor Position Sensing Detectors"
Jamelle Watson-Daniels '15
Physics
At Brown, I measure the current, capacitance, and voltage properties of silicon detectors manufactured in several different ways and also subjected to different radiation doses. In my project for the summer 2013, I started by measuring properties of detectors and learning new techniques at DESY in Hamburg, Germany, then continued my research on sensors at CERN in Geneva, Switzerland.
