Correlated ground based observations in support of the HEAO-1 X-ray observatory

Using X-ray and optical photometry of UBVRI fluxes, energetic compact extragalactic sources were studied, such as BL Lacerta (Lac) and BL Lac objects-Markarian (Mrk) 421, Mrk 501, and B2 1308+32. BL Lac and BL Lac objects were found to have predominantly nonthermal spectrums. Photometric and spectroscopic properties of X Persei, an unusual Be star associated with an intrinsically weak X-ray source, were also studied. Both its X-ray and optical emission show complex variability on many different time scales

The Search for Neutrino-Antineutrino Mixing from Lorentz Invariance Violation using Neutrino Interactions in MINOS

We searched for a sidereal modulation in the rate of neutrinos observed by the MINOS far detector. The detection of these signals could be a signature of neutrino-antineutrino mixing due to Lorentz and CPT violation as described by the Standard-Model Extension framework. We found no evidence for these sidereal signals and we placed limits on the coefficients in this theory describing the effect.Comment: Presented at the Sixth Meeting on CPT and Lorentz Symmetry, Bloomington, Indiana, June 17-21, 201

The Search for Neutrino-Antineutrino Mixing Resulting from Lorentz Invariance Violation using neutrino interactions in MINOS

We searched for a sidereal modulation in the rate of neutrinos produced by the NuMI beam and observed by the MINOS far detector. The detection of such harmonic signals could be a signature of neutrino-antineutrino mixing due to Lorentz and CPT violation as described by the Standard Model Extension framework. We found no evidence for these sidereal signals and we placed limits on the coefficients in this theory describing the effect. This is the first report of limits on these neutrino-antineutrino mixing coefficients.Comment: 11 pages, 2 figures, 3 table

Testing Lorentz and CPT Invariance with MINOS Near Detector Neutrinos

We present an analysis designed to search for Lorentz and CPT violations as predicted by the SME framework using the charged current neutrino events in the MINOS near detector. In particular we develop methods to identify periodic variations in the normalized number of charged current neutrino events as a function of sidereal phase. To test these methods, we simulated a set of 1,000 experiments without Lorentz and CPT violation signals using the standard MINOS Monte Carlo. We performed an FFT on each of the simulated experiments to find the distribution of powers in the sidereal phase diagram without a signal. We then injected a signal of increasing strength into the sidereal neutrino oscillation probability until we found a 5$\sigma$ deviation from the mean in the FFT power spectrum. By this method, we can establish upper limits for the Lorentz and CPT violating terms in the SME.Comment: 6 pages, 4 figures, CPT'07 Conference proceeding

1981-2021: The Early Development of the Marshall University Joan C. Edwards School of Medicine and its Department of Medicine

When we arrived in Huntington, the physician shortage was so extreme that we, who had great medical connections, found it difficult to locate physicians who accepted new patients. We invited the first class of medical students, the Class of 1981, who began medical school in January 1978, their spouses, and all faculty and spouses to our home for an evening of fellowship and food (Appendix 1: The First Graduating Class, the Class of 1981). The first class included twenty-four students, and everyone invited fit in our house for the gathering. Within three years, the medical students and staff had grown so much that they all no longer fit in our home. Since then, the School of Medicine has grown immensely. Class size now numbers about eighty medical students in each year and the faculty numbers several hundred
