Genetic Algorithm for SU(2) Gauge Theory on a 2-dimensional Lattice

An algorithm is proposed for the simulation of pure SU(N) lattice gauge theories based on Genetic Algorithms(GAs). We apply GAs to SU(2) pure gauge theory on a 2 dimensional lattice and show the results, the action per plaquette and Wilson loops, are consistent with those by Metropolis method(MP)s and Heatbath method(HB)s. Thermalization speed of GAs is especially faster than the simple MPs.Comment: 3 pages,9 figures,LATTICE98(Algorithm), "Genetic Algorithm for SU(N) Gauge Theory on a Lattice

Brief of Amici Curiae in Support of Appellant, James Townsend v. Midland Funding, LLC

The Consumer Protection Clinic of the University of Maryland Francis King Carey School of Law, filed a Motion to Participate and an Amicus Brief in the case of Townsend v. Midland Funding, LLC. The case presents the question of whether documents created by third party predecessors in interest—usually a bank—may be admitted into evidence when a debt buyer plaintiff does not demonstrate personal knowledge regarding any of the foundational elements which would be required to admit the documents under the business records exception to the hearsay rule. Amici urge the Court to overturn the lower court, and hold that a debt buyer’s documents may not be admitted into evidence without the debt buyer first laying the proper foundation for the business records exception to the hearsay rule. The Clinic was joined by AARP, the National Consumer Law Center, the National Association of Consumer Advocates, and by the Maryland Legal Aid Bureau and Maryland\u27s Public Justice Center. The Brief deals with the problems of data integrity and the lack of competent, reliable evidence in lawsuits filed purchasers of charged off credit card debt, known as debt buyers. The Consumer Protection Clinic and other amici examine due process and professionalism concerns which arise when our courts (primarily Maryland\u27s District Court) do not strictly apply the special evidentiary and procedural rules which exist for small claims actions

Asymmetries of Heavy Elements in the Young Supernova Remnant Cassiopeia A

Supernova remnants (SNRs) offer the means to study supernovae (SNe) long after the original explosion and can provide a unique insight into the mechanism that governs these energetic events. In this work, we examine the morphologies of X-ray emission from different elements found in the youngest known core-collapse (CC) SNR in the Milky Way, Cassiopeia A. The heaviest elements exhibit the highest levels of asymmetry, which we relate to the burning process that created the elements and their proximity to the center of explosion. Our findings support recent model predictions that the material closest to the source of explosion will reflect the asymmetries inherent to the SN mechanism. Additionally, we find that the heaviest elements are moving more directly opposed to the neutron star (NS) than the lighter elements. This result is consistent with NS kicks arising from ejecta asymmetries.Comment: 12 pages, 4 figures, 2 tables Updated to include an analysis of Emission Measure Maps (vs the, still-included, continuum-subtracted flux maps), used as another proxy for mass maps. The results have not changed; the emission measure maps also show increasing asymmetry with ejecta mass. (Now matches the version published in ApJ. Vol 889 Issue 2 (2020) 144
