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 […]
Probabilistic Inference and Ranking of Gene Regulatory Pathways as a Shortest-path Problem
James Jensen and Dr. Mark Clement, Department of Computer Science The project began in the Computational Science Lab in the Computer Science Department, where I was given the assignment of finding something useful to do with a collaborating biologist’s microarray data. Initially, the goal was to identify differentially expressed genes, and shifted to integrating differential […]
Sr+ Fluorescence Probe
Jarom Jackson and Dr. Dallin Durfee, Department of Physics and Astronomy Introduction The goal of this project was to stabilize a laser to use as an ion probe. The first part of the project was completed with some success, though the rest had to be postponed until other parts of the experiment are completed, and […]
Parameter Estimation Using a Continuous, Differentiable and Asymmetric Penalized Likelihood Function
Brian Holt and Dr. Dennis Tolley, Department of Statistics Per the original ORCA proposal, work has been done to estimate relative amounts of compounds from GC-MS (gas chromatography-mass spectrometry) data using an asymmetric penalized likelihood function. The initial results of this project were presented at the CPMS Student Research Conference in March of this year1. […]
Increasing Usefulness of Neutron Detectors through Gamma Shielding
Andrew Hoffman and Dr. Lawrence Rees, Department of Physics and Astronomy The BYU nuclear research group has over the past few years been attempting to design neutron detectors for the use of both scientists and homeland security applications. When radioactive materials are being transported, they can emit a broad spectrum of particles including gammas, betas, […]
Modeling of an Ion Exchange Reaction Involving Decamethylcucurbit[5]uril in the Gas Phase
Jacob Hedelius and Dr. David Dearden, Department of Chemistry and Biochemistry Mathematical modeling is both common and increasingly expected in scientific research, to both predict and to explain results. Models are used in many disciplines, from describing cellular process in biology, weather patterns in planetary science, to galaxies in physics. As part of my studies […]
