Analysing Friedel averages and differences.
Various practical applications of the average (A) and difference (D) of Friedel opposites are described. Techniques based on the resonant-scattering contribution to Friedel differences are applied to see whether a crystal is centrosymmetric or not, and to determine the point group of the crystal. For the validation of a structural study, plots of A(obs) against A(model), and D(obs) against D(mo...
متن کاملIntensity statistics of Friedel opposites.
A previous analysis of the average intensity and mean-square intensity difference of Friedel opposites, confined to the space group P1 [Flack & Shmueli (2007). Acta Cryst. A63, 257-265], is here extended to all the non-centrosymmetric space groups. The present analysis presumes purely non-centrosymmetric content of the unit cell. An important result of this study is that the average intensity a...
متن کاملCharles Spence
Working at the Crossmodal Research Laboratory in Oxford, Charles Spence tries to apply the latest insights from our growing neuroscience understanding of the rules governing multisensory integration to the design of better products, packages, places, interfaces, and foods, an area that can perhaps best be captured under the title of neuroscience-inspired multisensory design.
متن کاملCharles Spearman
Few would dispute the claim that Charles Edward Spearman (1863-1945) is Britain’s premier psychologist and indeed one of the enduring figures in the history of behavioral science. Some twenty years ago, I asked a number of psychologists to list the names of whomever they considered to be the five or six most important persons in the history of psychological testing. Among all the nominations, o...
متن کاملCharles Lyell
Pergamon Press, which has in recent years taken interest in matters neurophysiological, has collected the writings of 56 authors, from many countries, dealing with biochemical, physiological, pharmacological and behavioral aspects of nervous function. Most of the material is a succinct compilation of previously published observations; but some of it, such as the study by Smith, Stacey and Young...
