Transformation Acoustics in Generic Elastic Media

In this work a transformation acoustics scheme for generic elastic media is developed. Our approach starts form the decomposition of the elasticity tensor in terms of its eigentensors, an idea previously used by Norris. While Norris' transformation acoustics is restricted to the special class of so-called pentamode materials, we show that a similar scheme can be defined for the most general elasticity tensor. As in case of Norris' model (and in sharp contrast to transformation optics), the compatibility equations of the transformation medium are not purely algebraic and it is not guaranteed that solutions to these equations exist for any choice of material parameters and coordinate transformation. Nonetheless, it is shown that our scheme yields new cloaking solutions for certain classes of materials. In particular, we present the first application of a transformation based device for a non-scalar wave equation outside of the field of electromagnetics.Comment: 14 pages, LaTe

On the Values of Words

Mary Norris\u27 Between You and Me: Confessions of a Comma Queen and Kory Stamper\u27s Word by Word: The Secret Life of Dictionaries use observations about language as a touchstone for a nuanced examination of deeper truths about language, culture, and law in a changing world. In so doing, they point to deeper truths about the use of language and its consequences. Law students, lawyers, and law professors will benefit from journeying with Norris and Stamper towards the goal of crafting prose that is clear, accurate, and inclusive. In particular, the legal community will benefit from the books\u27 efforts to define consistent, binding linguistic rules and the books\u27 reflections on the consequences of language as a medium for conveying law

Bright Stars and Metallicity Spread in the Globular Cluster Omega Centauri

The globular cluster Omega Centauri (NGC 5139) is the most massive and brightest cluster in our Galaxy. It has also a moderately high mass to light ratio (3.6) and an anomalous flattening (0.83) for a globular cluster. This cluster is also very interesting because it is one of a few examples of globular clusters with a measurable spread in the metal abundance (see Da Costa & Willumsen 1981, Norris et al. 1996, and Suntzeff and Kraft 1996 and references therein) and then it offers a unique, big sample of nearby stars having all the same distance and reddening but showing different metallicity (and age ?) effects. A recent paper by Norris et al. (1997) shows also an interesting correlation between kinematics and metal abundance.Comment: 5 pages, 3 eps figure, pasconf.sty included, Proceedings of the Third Mount Stromlo Symposium: the Galactic Hal

(excerpt) Many species from all families of Rhopaloccra have been reported to drink water (Norris 1936). Bates (1863) noted that, in the Amazon, 80 species from 22 genera flocked about the damp edges of water and, with very few exceptions, all of these individuals were males
