Nathan Woodbury and Dr. Sean Warnick, Department of Computer Science Introduction My original purpose in this project was to “explore the nature of self-enforcing policies that induce participation in coalitions within a competitive environment.” In order to do this, I proposed to use a model of a general market of many suppliers. This model was to be […]
Identification of Novel Ribosome Stalling Peptides using the Tat-two Hybrid
Benjamin Van Leeuwen and Dr. Allen Buskirk, Department of Chemistry and Biochemistry Dr. Buskirk discontinued my previous project on discovering novel ribosomal stalling sequences shortly after the start of the semester because of its lack of relevance to more current ribosomal research trends. While there are still an unknown number of stalling sequences that have […]
Attosecond Pulse Generation Centered in the Visible
Daniel Thrasher and Dr. Scott Bergeson, Department of Physics and Astronomy From May through August I had the privilege of traveling to Tsing Hua National University in Taiwan to work in the lab of Professor Andy Kung and associates. The Office of Creative Research awarded me a grant to help cover travel and living expenses. […]
An Explanation of Strange Duality in terms of Landau-Ginzburg Mirror Symmetry
Rachel Suggs and Dr. Tyler Jarvis, Department of Mathematics Suppose you have a physical system that can jump suddenly between two stable states. Then a function modeling the system will have a singularity at the jump. Our singularities will all be dened by polynomials, such as x3y + y5 + z2. Mathematician V.I. Arnol’d studied such singularities in […]
Effect of Field Cooling on Magnetic Domain Memory in Exchange Coupled Thin Films
Matthew Rytting and Dr. Karine Chesnel, Department of Physics and Astronomy In my project, we proposed to investigate the effect of field cooling on magnetic domain memory in ferromagnetic films which are exchange coupled with antiferromagnetic material. We analyzed this memory using X-ray speckle correlation, and we performed complementary microscopy measurements so as to get […]
Asymmetric Magnetic Reconnection in Solar Eruption Events
Drake Ranquist and Dr. Victor Migenes, Department of Physics and Astronomy Space weather is of great interest due to its effects on orbiting satellites. The charged particles thrown off from the sun during eruption events like solar flares and coronal mass ejections (CMEs) can damage and destroy the electronics aboard spacecraft. They also warp Earth’s […]
Laser-Induced Fluorescence of NO2
Joseph Mosley and Dr. Jaron Hansen, Department of Chemistry and Biochemistry The effects of water vapor on the kinetics and product branching ratio of the reaction of organic peroxy radicals (RO2) with nitrous oxide are under investigation. Hyrdrocarbon combustion produces organic peroxy radicals which then react with NO to form NO2 or organic nitrates (RONO2). […]
How tmRNA/SmpB Rescue Complex binds to Stalled Ribosomes
Matthew McDowell and Dr. Allen Buskirk, Department of Chemistry and Biochemistry Abstract Ribosomes are large complexes made up of ribosomal RNA and proteins and are the site of protein synthesis. However, ribosomes occasionally run into problems during this process and will stall during translation. Fortunately, two molecules known as tmRNA and SmpB are made by […]
Quadratic Fields with 2-Skylow Class Group Isomorphic to C2kC2
Adele Lopez and Dr. Paul Jenkins, Department of Mathematics We prove that there are innitely many imaginary quadratic fields with 2-class group isomorphic to C2kC2 for any given positive integer k. This work is based on a related result for cyclic 2-class groups by Dominguez, Miller and Wong, and our proof proceeds similarly. However, we […]
An Algorithmic Approach for Real-‐time Music Improvisation
Denna Lawrence and Dr. Sean Warnick, Department of Computer Science Project Purpose I developed an algorithm that generated musical accompaniment to real-time improvisation from a soloist and analyzed my results using well-defined conditions of harmonization. Project Background Many electronic keyboards have a feature called “auto accompaniment”. When in that mode, the keyboard plays a chord when the performer […]
