Washington Case Law—1959; Constitutional Law

Presented below is the seventh annual Survey of Washington Case Law. The articles in this survey issue have been written by second-year students as a part of their program to attain status as nominees to the Law Review. The second-year students were guided in their work by the Casenote Survey Editor of the Law Review and by various members of the law school faculty. The case survey issue does not represent an attempt to discuss every Washington case decided in 1959. Rather, its purpose is to point out those cases which, in the opinion of the Editorial Board, constitute substantial additions to the body of law in Washington. The Constitutional Law section covers cases on released time for religious instruction during school days—constitutional aspects of school participation in religious program (Thomas) and on the compulsory school attendance law—freedom of religion (Clifford)

Evidence-based retrieval in evidence-based medicine

pre-printObjective: Clinical decisions based on a meta-analysis that is based on an ineffective retrieval strategy may have serious negative consequences for patients. The study objective was to investigate the extent to which meta-analyses report proof of their retrieval strategies' effectiveness. Methods: The authors examined a random sample (n 5 100) of articles in the 1996 to 2002 full-text subset of Ovid MEDLINE indexed as ‘‘meta-analysis.'' We classified the articles in three ways: the article (A) reported both a retrieval strategy in sufficient detail (such that it could be repeated) and with evidence of the strategy's effectiveness, (B) reported a retrieval strategy in sufficient detail but not with evidence of the strategy's effectiveness, or (C) neither reported a strategy in detail nor evidence of the strategy's effectiveness. Articles classified as (A) were further classified according to the level of evidence reported. Results: Of the eighty-nine articles in our final analysis, six (6.7%) were classified as category (A), fifty-seven (64%) as (B), and twenty-six (29%) as (C). Articles in category (A) reported a previously validated search, a published strategy, or strategy based on expert opinion. Conclusion: Peer-review standards must be developed that require authors of meta-analyses to report evidence for the effectiveness of their retrieval strategies

Improving Holographic Search Algorithms using Sorted Pixel Selection

Traditional search algorithms for computer hologram generation such as Direct Search and Simulated Annealing offer some of the best hologram qualities at convergence when compared to rival approaches. Their slow generation times and high processing power requirements mean, however, that they see little use in performance critical applications. This paper presents the novel Sorted Pixel Selection (SPS) modification for Holographic Search Algorithms (HSAs) that offers Mean Square Error (MSE) reductions in the range of 14:7 19:2% for the test images used. SPS operates by substituting a weighted search selection procedure for traditional random pixel selection processes. While small, the improvements seen are observed consistently across a wide range of test cases and require limited overhead for implementatio

A grid of 800,000 models of delta Scuti stars using MESA and GYRE

The rapidly increasing number of delta Scuti stars with regular patterns among their pulsation frequencies necessitates modelling tools to better understand the observations. Further, with a dozen identified modes per star, there is potential to make meaningful inferences on stellar structure using these young $\delta$ Sct stars. We compute and describe a grid of $>$800,000 stellar models from the early pre-main-sequence to roughly one third of the main-sequence lifetime, and calculate their pulsation frequencies. From these, we also calculate asteroseismic parameters and explore how those parameters change with mass, age, and metal mass fraction. We show that the large frequency separation, $\Delta\nu$, is insensitive to mass at the zero-age main sequence. In the frequency regime observed, the $\Delta\nu$ we measure (from modes with $n\sim5$--9) differs from the solar scaling relation by $\sim$13%. We find that the lowest radial order is often poorly modelled, perhaps indicating that the lower-order pressure modes contain further untapped potential for constraining the stellar structure. We also show that different nuclear reaction networks available in MESA can affect the pulsation frequencies of young $\delta$ Sct stars by as much as 5%. We apply the grid to five newly modelled stars, including two pre-main-sequence stars each with 15+ modes identified, and we make the grid available as a community resource.Comment: 17 pages including appendices.
