Study on blast-induced ground vibration velocity limits for slope rock masses
Frontiers in Earth Science, 2023 Seismic waves induced by blasting can cause damage to slope rock masses and thus lower the stability of the slope. The vibration standards of many countries do not specify the allowable blasting vibration velocity for slope rock masses.

BLAST++: BLASTing queries in batches [PDF]
Bioinformatics, 2003 Abstract Summary: BLAST++ is a tool that is integrated with NCBI BLAST, allowing multiple, say K, queries to be searched against a database concurrently. The results obtained by BLAST++ are identical to that obtained by executing BLAST on each of the K queries, but BLAST++ completes the processing in a much shorter time ...
