Hugo Williams, self-styled anglo-american poet

Although his poetry gives every appearance of being pre-eminently 'English', Hugo Williams claims he is an 'Anglo-American' poet. This surprising assertion rests on his enthusiastic embrace of American popular culture as well as the construction of a style out of American Imagist, "Objectivist" and Confessional strategies. Both elements of the epithet Anglo-American are examined in relation to the poet's work and in the process Williams' claim is shown to be unsustainable, yet at the same time highly revealing of currents within English literary culture

Periodicities of Quasar Redshifts in Large Area Surveys

We test the periodicity of quasar redshifts in the 2dF and SDSS surveys. In the overall surveys redshift peaks are already apparent in the brighter quasars. But by analyzing sample areas in detail it is shown that the redshifts fit very closely the long standing Karlssson formula and strongly suggest the existence of preferred values in the distribution of quasar redshifts. We introduce a powerful new test for groups of quasars of differing redshifts which not only demonstrates the periodicity of the redshifts, but also their physical association with a parent galaxy. Further such analyses of the large area surveys should produce more information on the properties of the periodicity.Comment: 23 pages, 14 figure

K-orbit closures on G/B as universal degeneracy loci for flagged vector bundles with symmetric or skew-symmetric bilinear form

We use equivariant localization and divided difference operators to determine formulas for the torus-equivariant fundamental cohomology classes of $K$-orbit closures on the flag variety $G/B$, where G = GL(n,\C), and where $K$ is one of the symmetric subgroups O(n,\C) or Sp(n,\C). We realize these orbit closures as universal degeneracy loci for a vector bundle over a variety equipped with a single flag of subbundles and a nondegenerate symmetric or skew-symmetric bilinear form taking values in the trivial bundle. We describe how our equivariant formulas can be interpreted as giving formulas for the classes of such loci in terms of the Chern classes of the various bundles.Comment: Minor revisions and corrections suggested by referees.

The Goldstone solar system radar: A science instrument for planetary research

The Goldstone Solar System Radar (GSSR) station at NASA's Deep Space Communications Complex in California's Mojave Desert is described. A short chronological account of the GSSR's technical development and scientific discoveries is given. This is followed by a basic discussion of how information is derived from the radar echo and how the raw information can be used to increase understanding of the solar system. A moderately detailed description of the radar system is given, and the engineering performance of the radar is discussed. The operating characteristics of the Arcibo Observatory in Puerto Rico are briefly described and compared with those of the GSSR. Planned and in-process improvements to the existing radar, as well as the performance of a hypothetical 128-m diameter antenna radar station, are described. A comprehensive bibliography of referred scientific and engineering articles presenting results that depended on data gathered by the instrument is provided

Useful entanglement can be extracted from all nonseparable states

We consider entanglement distillation from a single-copy of a multipartite state, and instead of rates we analyze the "quality" of the distilled entanglement. This "quality" is quantified by the fidelity with the GHZ-state. We show that each not fully-separable state $\sigma$ can increase the "quality" of the entanglement distilled from other states, no matter how weakly entangled is $\sigma$. We also generalize this to the case where the goal is distilling states different than the GHZ. These results provide new insights on the geometry of the set of separable states and its dual (the set of entanglement witnesses).Comment: 7 page

Republican States Bolstered Their Health Insurance Rate Review Programs Using Incentives From the Affordable Care Act.

The Affordable Care Act (ACA) included financial and regulatory incentives and goals for states to bolster their health insurance rate review programs, increase their anticipated loss ratio requirements, expand Medicaid, and establish state-based exchanges. We grouped states by political party control and compared their reactions across these policy goals. To identify changes in states rate review programs and anticipated loss ratio requirements in the individual and small group markets since the ACAs enactment, we conducted legal research and contacted each states insurance regulator. We linked rate review program changes to the Centers for Medicare and Medicaid Services (CMS) criteria for an effective rate review program. We found, of states that did not meet CMSs criteria when the ACA was enacted, most made changes to meet those criteria, including Republican-controlled states, which generally oppose the ACA. This finding is likely the result of the relatively low administrative burden associated with reviewing health insurance rates and the fact that doing so prevents federal intervention in rate review. However, Republican-controlled states were less likely than non-Republican-controlled states to increase their anticipated loss ratio requirements to align with the federal retrospective medical loss ratio requirement, expand Medicaid, and establish state-based exchanges, because of their general opposition to the ACA. We conclude that federal incentives for states to strengthen their health insurance rate review programs were more effective than the incentives for states to adopt other insurance-related policy goals of the ACA

Generalized inverses of matrices over a finite field

AbstractFor a given m × n matrix A of rank r over a finite field F, the number of generalized inverses, of reflexive generalized inverses, of normalized generalized inverses, and of pseudoinverses of A are determined by elementary methods. The more difficult problem of determining which m × n matrices A of rank r over F have normalized generalized inverses and which have pseudoinverses is solved. Moreover, the number of such matrices which possess normalized generalized inverses and the number which possess pseudoinverses are found
