X-ray Diffraction
X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information. Since many materials can form crystals—such as salts, metals, minerals, semiconductors, as well as various inorganic, organic, and biological molecules—X-ray crystallography has been fundamental in the development of many scientific fields. In its first decades of use, this method determined the size of atoms, the lengths and types of chemical bonds, and the atomic-scale differences among various mat ...

Extensible Resource Descriptor
Background The XML format used by XRDS was originally developed in 2004 by the OASIS XRI (extensible resource identifierTechnical Committeeas the resolution format for XRIs. The acronym XRDS was coined during subsequent discussions between XRI TC members and OpenID developers at firsInternet Identity Workshopheld in Berkeley, CA in October 2005. The protocol for discovering an XRDS document from a URL was formalized as the Yadis specification published bYadis.orgin March 2006. Yadis became the service discovery format for OpenID 1.1. A common discovery service for both URLs and XRIs proved so useful that in November 2007 thXRI Resolution 2.0specification formally added the URL-based method of XRDS discovery (Section 6). This format and discovery protocol subsequently became part o XRDS Simple In early 2008, work on OAuth discovery by Eran Hammer-Lahav led to the development of XRDS Simple, a profile of XRDS that restricts it to the most basic elements and introduces some ext ...
