We provide simple, faster algorithms for the detection of cliques and dominating sets of fixed order. Our algorithms are based on reductions to rectangular matrix multiplication. We also describe an improved algorithm for diamonds detection.

Hydrogen-related infrared absorption bands in natural diamonds have been extensively investigated and widely used to identify natural, treated, synthetic grown by high pressure temperature (HPHT) chemical vapor deposition (CVD) techniques. However, the evolutional behavior of hydrogen-related defects relationship between nitrogen-related HPHT-treated Ib are unclear. In this article, defects, pa...

The nitrogen-vacancy areas found in diamonds provide fast, accurate, real-time magnetic vector measurements
