Three-Loop Contributions To Hyperfine Splitting: Muon Loop Light-By-Light Insertion And Other Closed Lepton Loops, Michael I. Eides, Valery A. Shelyuto

Physics and Astronomy Faculty Publications

The muon and tauon light-by-light scattering contributions to hyperfine splitting in muonium are calculated. These results conclude the calculation of all hard three-loop contributions to hyperfine splitting generated by the graphs with closed fermion loops. We discuss the special role that the lepton anomalous magnetic moments play in these calculations. The full result for all three-loop radiative-recoil corrections to hyperfine splitting generated by the graphs with closed lepton loops is presented.

We investigate of the properties of ~2000 Herschel/SPIRE far-infrared-selected galaxies from 0 < z < 4 in the CFHTLS-D1 field. Using a combination of extensive spectroscopy from the VVDS and ORELSE surveys, deep multiwavelength imaging from CFHT, VLA, Spitzer, XMM-Newton, and Herschel, and well-calibrated spectral energy distribution fitting, Herschel-bright galaxies are compared to optically-selected galaxies at a variety of redshifts. Herschel-selected galaxies are observed to span a range of stellar masses, colors, and absolute magnitudes equivalent to galaxies undetected in SPIRE. Though many Herschel galaxies appear to be in transition, such galaxies are largely consistent with normal star-forming galaxies when rest-frame colors are utilized. The nature of the star-forming “main sequence” is studied and we warn against adopting this …

Utilizing Landsat Tm And Oli In Predicting Oncomelania Hupensis Habitats Around Poyang Lake Before And After Three Gorges Dam Completion, Stephanie L. Mccracken

Honors Theses

Schistosomiasis is a parasitic disease caused by the Schistomsoma japonicum flatworm that utilizes the Oncomelania hupensis snail as an intermediate agent. In the People’s Republic of China, these amphibious snails contaminate freshwater systems infecting humans, bovines, and other mammals and have caused significant morbidity for over two thousand years (Wertheim, et al. 2012; Zhang, et al. 2012.) The gravity of this disease prompted the national government to initiate sizable public health programs, such as the World Bank Loan Project (WBLP.) In spite of WBLP's achievements, in 2004, after this program ended, a national survey acknowledged a resurgence of schistosomiasis in …

Automated Classification Of Eeg Signals Using Component Analysis And Support Vector Machines, Priya Balasubramanian

Masters Theses

Epileptic seizures are characterized by abnormal electrical activity occurring in the brain. EEG records the seizures demonstrating changes in signal morphology. These signal characteristics, however, differ between patients as well as between different seizures in the same patient. Epilepsy is managed with anti-epileptic medications but in some extreme cases surgery might be necessary. Non-invasive surface electrode EEG measurement gives an estimate of the seizure onset but more invasive intra-cranial electrocorticogram (ECoG) are required at times for precise localization of the epileptogenic zone.

The epileptogenic zone can be described as the cortical area targeted for resection to render the patient symptom …

Protein Turnover In Broiler, Layers, And Broiler Breeders, Karen Vignale Lake

Graduate Theses and Dissertations

Protein turnover in skeletal tissue for broiler breeders has shown to increase at sexual maturity and then decline with increased egg production. Regarding broiler chickens the industry is facing two situations that need to be clarified: the appearance of white stripes in birds over 56 days of age and the positive effect in breast meat yield that supplementation of 25OH-D3 is causing. A series of studies were conducted to determine the effect of sexual maturity in protein turnover in broiler breeders and laying hens and to understand the effect of 25OHD3 in breast meat yield in broiler chickens and why …

Online Detection Of Outliers And Structural Breaks Using Sequential Monte Carlo Methods, Richard Wanjohi

Graduate Theses and Dissertations

Outliers and structural breaks occur quite frequently in time series data. Whereas outliers often contain valuable information

about the process under study, they are known to have serious negative impact on statistical data analysis. Most obvious effect is model misspecification and biased parameter estimation which results in wrong conclusions and inaccurate predictions. Structural time series consist of underlying features such as level, slope, cycles or seasonal components. Structural breaks are permanent disruptions of one or more of these components and might be a signal of serious changes in the observed process.

Detecting outliers and estimating the location of structural breaks …

Incarcerating Exceptional Pupils: Is There A School-To-Prison Pipeline In Eastern Oklahoma?, Brett Alan Fitzgerald

Graduate Theses and Dissertations

The school-to-prison pipeline metaphor represents an educational environment that allows public schools to push many at-risk children out of school and into the juvenile justice system or even worse, the adult criminal justice system (Wald and Losen, 2003; Lynn, 2010; Tuzzolo and Hewitt, 2006). The purpose of this study is to examine whether a school-to-prison pipeline exists in eastern Oklahoma, and if so, to better understand the characteristics of the public schools that may be contributing to it. The school-to-prison pipeline metaphor guided three research questions regarding whether certain public schools in eastern Oklahoma referred greater percentages of their students, …
