Parallel SAH k-D tree construction
The k-D tree is a well-studied acceleration data structure for ray tracing. It is used to organize primitives in a scene to allow efficient execution of intersection operations be...

RIATA-HGT: A Fast and Accurate Heuristic for Reconstructing Horizontal Gene Transfer
Horizontal gene transfer (HGT) plays a major role in microbial genome diversiļ¬cation, and is claimed to be rampant among various groups of genes in bacteria. Further, HGT is a ma...
