A multiple wavelength x-ray source includes a multi-thickness target, having at least a first and a second thickness. The first thickness can substantially circumscribe the second thickness. An electron beam can be narrowed to impinge primarily upon second thickness or expanded to impinge primarily ...

Reps of pCRESS4 through 8 contain closely similar sequence motifs within the nuclease and helicase domains (Fig.3), consistent with the results of the clustering and phylogenetic analyses (Fig.2). In particular, these 5 pCRESS groups share a specific signature, YLxH (x, any amino acid) wit...

Development of X-ray double crystal rocking curve setup A Double Crystal Rocking Curve setup has been developed in the non dispersive (+ -) configuration for the analysis of crystalline perfection in bulk single crystals and epitaxial layers. The X-rays from a conventional laboratory source h......
Each sensor node has a limited power source for network functionality, thereby reducing the network’s lifetime. To amend the above challenge, atmost energy or computationally intensive tasks are transferred to the controller. It is also responsible for the resource management and control process (...
on. Source data are provided as a Source Data file. Full size image Furthermore, we find the observed dental-dietary patterns derive from the correlated evolution of tooth complexity and plant-based diets under highly variable rates of phenotypic evolution. Our results show strong support for a ...
The potential in macromolecular crystallography for using multiple crystals to collect X-ray diffraction data simultaneously from assemblies of up to seven crystals is explored. The basic features of the algorithms used to extract data and their practical implementation are described. The procedure could...
