The key features leading to low-energy grain boundaries in metals are discussed by reference to computersimulated structures and geometrical analysis in terms of atom packing. Low energy is found to be associated with boundary structures consisting of relatively dense packing, and this can in turn be expressed in terms of the space-filling packing of coordination polyhedra. The geometrical meth...

False-positive classification is a central issue for RFID environments with limited process control, such as in-store settings. In the case of electronic article surveillance, false positives not only lead to incorrect inventory data but also trigger false alarms, which impair customer satisfaction. A typical counter measure is to reduce antenna power, which in turn leads to greatly diminished ...

We present a definition of Riemannian manifold in noncommutative geometry. Using products of unbounded Kasparov modules, we show one can obtain such Riemannian manifolds from noncommutative spinc manifolds; and conversely, in the presence of a spinc structure. We also show how to obtain an analogue of Kasparov's fundamental class for a Riemannian manifold, and the associated notion of Poincaré ...

The sensitivity of the calculated matter radius to the binding energy is exploited to estimate the 2n binding energy of 22C, using a recent experimental value of Rm=5.4(9) fm. The result is B2n < 220 keV, significantly smaller than another recent estimate. Disciplines Physical Sciences and Mathematics | Physics Comments Fortune, H. T. and Sherr, R. (2012).

OBJECTIVE The objective of this article is to discuss the reasons that manuscripts fail to be published and to establish some principles for increasing the likelihood of publication. CONCLUSION Many good manuscripts fail to be published because they violate a few simple rules for writing a superior journal article. This review presents 10 principles for increasing the likelihood of manuscript...

The aim of the current study is to examine the influence of the victim's, perpetrator's, and participant's ethnicity on victim and perpetrator blame attributions. Additionally, comparisons between males and females and a community and student sample were made. Participants read a rape vignette in the form of a newspaper article and subsequently attributed victim and perpetrator blame. A 2 (vict...

Perlmutter (1970) argued that the indefinite article is categorically different from the definite article and proposed that it is a clitic version of the numeral "one". But there are, as Perlmutter himself pointed out, instances of "a" as well as of "one" that don't seem to have the semantics of the numeral. Hence a divorce of "a" (and of "one") from "numeral"-hood is called for. Furthermore, t...
