Experimental Bell Inequality Violation with an Atom and a Photon

We report the measurement of a Bell inequality violation with a single atom and a single photon prepared in a probabilistic entangled state. This is the first demonstration of such a violation with particles of different species. The entanglement characterization of this hybrid system may also be useful in quantum information applications.Comment: 4 pages, 2 figure

Quantum harmonic oscillator state synthesis and analysis

Experiments are described in which a single, harmonically bound, beryllium ion in a Paul trap is put into Fock, thermal, coherent, squeezed, and Schroedinger cat states. Experimental determinations of the density matrix and the Wigner function are described. A simple calculation of the decoherence of a superposition of coherent states due to an external electric field is given.Comment: 13 pages, LaTeX2e, special style file spie.sty included, 11 eps figures included using epsfig, graphicx, subfigure, floatflt macros.

Spatial Variation in the Rates of Unemployment in Ohio By County, January 1981-July 1982

Author Institution: Department of Geography, University of AkronSpatial patterns of unemployment by county in Ohio are analyzed using quarterly labor statistics from January 1981 to July 1982. A cluster analysis grouped the 88 counties into 3 primary regions, 2 secondary groups, and 3 outlier counties. Eighty of the counties lie in the 3 primary groups, which are characterized as low, average, and high unemployment areas in relation to the statewide trend in unemployment during this period. Counties in the low unemployment group have a diversified economy and are generally located in the central corridor of Ohio extending from Cincinnati to Cleveland. Counties in the high unemployment region are located primarily in southern Ohio and contain a rural population with a high level of poverty. The county unemployment rates are also correlated with the percentage of employment concentrated in the major economic sectors. The manufacturing and agricultural sectors show positive correlations to unemployment, whereas finance, insurance, and real estate (F.I.R.E.), services, and trade show strong negative correlation

B/LV Laboratory Accessibility Technology Adapted for Neurodiverse Chemistry Students

Text-to-speech technology is a common accommodation available for students with disabilities. Despite the ubiquitous nature of text-to-speech, this technology has not been explored in laboratory settings for neurodiverse college students. This study explores the adaptability of laboratory accessible text-to-speech technology (originally developed for blind/low vision (B/LV) students) for neurodiverse students. Students were asked to provide general feedback about the usability and effectiveness of the technology using Likert surveys. The students also answered open-ended questions about how the technology could be adapted to be more neurodiverse friendly. Overall, more than 50% of the students found the technology useful but had specific feedback about adaptations that could make it even more universal
