The Influence of Electrostatic Truncation on Simulations of Polarizable Systems

Different schemes for the treatment of long-ranged electrostatic interactions will be examined for water simulations using the polarizable fluctuating charge potential. Several different methods are compared, including Ewald sums, potential shifting, spherical truncation and reaction field corrections. For liquid water, properties such as the energy, pressure, dynamics and structure are more sensitive to the treatment of the long-ranged interactions with polarizable than with non-polarizable potentials.Comment: 4 figures, 13 pages, to be published in the Proceedings from the Workshop on Treatment of Electrostatic Interactions in Computer Simulations of Condensed Mediaof Con

New genera, species, and records of Acanthocinini (Coleoptera: Cerambycidae: Lamiinae) from Hispaniola

Two new genera of Acanthocinini (Coleoptera: Cerambycidae), Luctithonus Lingafelter and Duocris­tala Lingafelter, are described from Hispaniola. Two new species of Luctithonus are described: Luctithonus aski Lingafelter and L. duartensis Lingafelter. A third species, L. pantherinus (Zayas), is newly recorded from Hispan­iola and the Dominican Republic (new country record), and transferred from Sternidius Haldeman as a new combination. Additional new species of Lamiinae are described from Hispaniola: Eugamandus albipumilus Lingafelter; Leptostylopsis opuntiae Lingafelter; and Lethes turnbowi Lingafelter. Keys to tribes of Lamiinae, genera of Acanthocinini, and species of Luctithonus in Hispaniola are included

Rethinking sport, empire, and American exceptionalism

This article examines the correlation between sports history and American imperialism and exceptionalism. More specifically, the author argues against a view of sport historiography which excludes debates within social and cultural history. It is the author's suggestion that established themes in sports historiography, when considered within the context of American imperialism, can expand the understanding of American sports within global history, in effect, allowing sports historians to generate effective cross-cultural analysis. Particular focus is given by the author to the emphasis on how historical generalizations and anecdotes establish imperialism in the sporting history of America

High Energy Cosmic Neutrinos

While the general principles of high-energy neutrino detection have been understood for many years, the deep, remote geographical locations of suitable detector sites have challenged the ingenuity of experimentalists, who have confronted unusual deployment, calibration, and robustness issues. Two high energy neutrino programs are now operating (Baikal and AMANDA), with the expectation of ushering in an era of multi-messenger astronomy, and two Mediterranean programs have made impressive progress. The detectors are optimized to detect neutrinos with energies of the order of 1-10 TeV, although they are capable of detecting neutrinos with energies of tens of MeV to greater than PeV. This paper outlines the interdisciplinary scientific agenda, which span the fields of astronomy, particle physics, and cosmic ray physics, and describes ongoing worldwide experimental programs to realize these goals.Comment: 15 pages, 9 figures, talk presented at the Nobel Symposium on Particle Physics and the Universe, Sweden, August 199
