Macromolecular envelope determination and envelope-based phasing
Acta Crystallographica Section D Biological Crystallography, 2006Small-angle X-ray scattering (SAXS) or electron-microscopy (EM) data have proven to be very useful in providing low-resolution structural details of proteins and other macromolecules. To utilize the envelope information for crystallographic phasing, it is essential to develop a method for correctly positioning the known envelope in a crystallographic ...

What Is so Special about Shoebox Halls? Envelopment, Envelopment, Envelopment
Acoustics Today, 2009Studies by Ando (1985) and Beranek (1996, 2004) have identified quantitative factors that contribute to hall quality. In approximate order of importance, these are: (1) listener envelopment, that is, the sense of being surrounded by sound, in particular, in the time period greater than 80 milliseconds after the arrival of the first sound; (2 ...
