We present the optical luminosity function (LF) of gamma-ray bursts (GRBs) estimated from a uniform sample of 58 GRBs from observations with the Robotic Optical Transient Search Experiment III (ROTSE-III). Our GRB sample is divided into two sub-samples: detected afterglows (18 GRBs) and those with upper limits (40 GRBs). We derive R-band fluxes for these two sub-samples 100 s after the onset of the burst. The optical LFs at 100 s are fitted by assuming that the co-moving GRB rate traces the star formation rate. While fitting the optical LFs using Monte Carlo simulations, we take into account the …

Magnetometer Surveys: Attempts And Issues In Locating A 1948 Private Water Well On The Shore Of Lac Sault Dore, Price County, Wisconsin, Kenneth R. Neuhauser, Kristopher J. Neuhauser
The Compass: Earth Science Journal of Sigma Gamma Epsilon
Two different magnetometer surveys in northern Wisconsin during the summers of 1997 and 2010, using two different Geometrics magnetometers, a proton precession G-816 unit and a cesium vapor G-858 unit, in an attempt to locate a surface-target position of, and depth to, an abandoned 1948 private water well, successfully targeted the suspect surface position and the depth to the well head spike. Both surveys detected 400-gamma anomalies and estimated the depth to the spike at 2 meters. A land owner, private family photograph taken in 1951, was used to compare the anomaly’s position to the actual surface position of the …

Evidence Of Large Scale Tectonic Processes On The Tharsis Rise, Mars, Genevieve Kidman, John S. Maclean, David Maxwell
Evidence Of Large Scale Tectonic Processes On The Tharsis Rise, Mars, Genevieve Kidman, John S. Maclean, David Maxwell
The Compass: Earth Science Journal of Sigma Gamma Epsilon
Past observations of Mars have led scientists to believe that tectonic kinematics stopped early in its planetary development. Recent exploration of Mars has led to new theories that support an active tectonic regime on the Tharsis rise. With the advancement of new satellite imagery and technologies such as Thermal Emission Imaging System, High Resolution Imaging Science Experiment satellite imagery, the Mars Orbital Laser Altimeter, and interactive software such as J-Mars and Esri GIS, we have identified additional large-scale surface features in the Tharsis Rise and surrounding areas. Large-scale Martian lineations, folds, and conjugate joints can be compared to similar structures …

Air Mass Frequency During Precipitation Events In The Northern Plains Of The United States, Anthony Baum, Richard De Pasquale, Melissa L. Godek
Air Mass Frequency During Precipitation Events In The Northern Plains Of The United States, Anthony Baum, Richard De Pasquale, Melissa L. Godek
The Compass: Earth Science Journal of Sigma Gamma Epsilon
Since 1980, numerous billion-dollar disasters have affected the Northern Plains of the United States, including nine droughts and four floods. The atmospheric environment present during precipitation events can largely be described by the presiding air mass conditions since air masses characterize a multitude of meteorological variables at one time over a large region. The goal of this research is to add knowledge to current understandings of the factors responsible for precipitation in the Northern Plains through an assessment of synoptic air mass conditions. The Spatial Synoptic Classification is used to categorize 30 years of daily surface air mass types across …

Background: DNA methylation is a widely studied epigenetic phenomenon; alterations in methylation patterns influence human phenotypes and risk of disease. As part of the Atherosclerosis Risk in Communities (ARIC) study, the Illumina Infinium HumanMethylation450 (HM450) BeadChip was used to measure DNA methylation in peripheral blood obtained from ~3000 African American study participants. Over 480,000 cytosine-guanine (CpG) dinucleotide sites were surveyed on the HM450 BeadChip. To evaluate the impact of technical variation, 265 technical replicates from 130 participants were included in the study.
Results: For each CpG site, we calculated the intraclass correlation coefficient (ICC) to compare variation of methylation levels …

The Magnetopause: Bringing Space Physics Into A Junior Lab, Jim Crumley, Ari Palczewski,, Stephen Kaster
The Magnetopause: Bringing Space Physics Into A Junior Lab, Jim Crumley, Ari Palczewski,, Stephen Kaster
MapCores Faculty Publications
Undergraduate students often have minimal exposure to many subfields
of physics which are active areas of research. Space physics
is an area that is particularly difficult to expose students to since
it builds off of another area that most undergraduates see little of,
plasma physics. The magnetopause is convenient entry point
into space physics, since it can be modeled as a pressure balance, which is
a concept familiar from introductory physics. We use the Earth's
magnetopause as the basis for a lab for junior physics majors. In
the lab students analyze results from a NASA MHD simulation and
data from …

Effect Of Australian Pine (Casuarina Equisetifolia) Canopy Density On The Understory Plant Community On San Salvador, Bahamas, Jeffry Anderson, Anna Baumgartner
Celebrating Scholarship & Creativity Day (2011-2017)
Casuarina equisetifolia, or Australian pine, is an invasive angiosperm species on the island of San Salvador, The Bahamas. It was originally found only in Southeast Asia and Australia. This tree is unique in that its leaves are much reduced and occur in whorls around the photosynthetic branchlets. It has been established that this tree contributes to the increased erosion of sediment on the dunes of San Salvador (Sealey 1998). This study investigated several possible factors contributing to differences in the understory plant community which may contribute to this erosion including leaf litter density, shading, and soil pH. It is …

Tiny Homes: Improving Carbon Footprint And The American Lifestyle On A Large Scale, Timothy Michael Carlin
Celebrating Scholarship & Creativity Day (2011-2017)
Since the year 1950, the size of the average American house has increased by two and one half times, from 1,000 Square Feet to 2,400 Square Feet. The drastic growth in housing size has led to increased spending and usage of utilities (natural gas, electricity, etc.), resulting in surges in the American carbon footprint. This research explores the potential for tiny homes to serve as a solution to the elusive idea of sustainable housing that is available to the average American homeowner, aiding in the size reduction of the American carbon footprint. Utilizing existing literature on the topic of tiny …

Classification Of Biorenewable Multiblock Copolymers, Sean Pickthorn
Celebrating Scholarship & Creativity Day (2011-2017)
Recent advances in polymer production sciences have led to an increase in research in sustainable practices. Our efforts intended to produce a toughened biorenewable multiblock copolymer. Polylactide has been noted to be produced by sustainable practices but is limited because of the fragile structure. To improve the brittle behavior of polylactide, preparation of polylactide-b-polybutadiene-b-polylactide multiblock copolymers were synthesized with a fixed weight of dihydroxyl polybutadiene (~3000 and ~2000g/mole series) and variable volume percent (50-90%) of both semicrystalline poly(L-lactide) and amorphous poly(D,L-lactide). Producing a multiblock copolymer intended to strengthen the mechanical properties by bridging and gapping over several domains. Initially, triblock …

An Applied Geophysical Detection And Subsequent Mitigation Of An Abandoned Well Casing Penetrating The Permian Hutchinson Salt At An Undisclosed Kansas Salt Mine, Kenneth R. Neuhauser, Daniel J. Redetzke
The Compass: Earth Science Journal of Sigma Gamma Epsilon
A surface field survey, using a cesium magnetometer, successfully targeted the spatial location of an abandoned buried well casing. Surface excavation exposed the top of the well casing, but attempts to drill out the casing from the surface failed due to the difficulty of keeping the drill bit on-line with the casing. The casing was successfully sealed off by grouting through the ceiling and floor from within the mine.

Base Metals Prospecting In Kagera Region, Tanzania Using Remote Sensing And Biogeochemistry Analytics, Thomas A. Woolman
The Compass: Earth Science Journal of Sigma Gamma Epsilon
This paper explores the use of biogeochemistry as a means for conducting geological prospecting in search of economic grade anomalies of precious metals, base metals and rare earth elements. The use of randomized soil sampling for geostatistical coefficient calculations and aeromagnetic remote sensing systems in conjunction with biogeochemical prospecting for ferromagnetic elements is examined. The paper concludes that the evidence presented indicates that bioprospecting can be an extremely powerful economic geology tool for conducting rapid and cost effective micro-targeting mineral discovery.

Modeling Tolerance In Dynamic Social Networks, Amanda Luby
Modeling Tolerance In Dynamic Social Networks, Amanda Luby
Honors Theses, 1963-2015
The study of social networks has become increasingly important in recent years. Multi-agent systems research has proven to be an effective way of representing both static and dynamic social networks in order to model and analyze many different situations. Previous implementations of multi-agent systems have observed a phenomenon called tolerance between agents through simulation studies, which is defined as an agent maintaining an unrewarding connection. This concept has also arisen in the social sciences through the study of networks. We aim to bridge this gap between simulation studies in multi-agent systems and real-world observations. This project explores how local interactions …
Measuring Ultrashort Laser Pulses Using Frequency-Resolved Optical Gating In Conjunction With Genetic And Iterative Algorithms, Alexandra M. Brancale
Measuring Ultrashort Laser Pulses Using Frequency-Resolved Optical Gating In Conjunction With Genetic And Iterative Algorithms, Alexandra M. Brancale
Honors Theses, 1963-2015
Precise ultrashort light pulse measurements are critical in many physics experiments using ultrafast lasers. A Frequency-Resolved Optical Gating (FROG) system can efficiently and accurately record these desired measurements. FROGs split the input laser beam, delay half of the beam, and overlap both halves in a nonlinear medium. The resulting beam allows the retrieval of phase and duration information. A data file is created by the FROG software that includes beam intensity measurements. By using genetic and iterative algorithms, the intensity data can be manipulated in order to retrieve the pulse duration and phase information. One focus of this research was …
