BLAST++: BLASTing queries in batches

BLAST++: BLASTing queries in batches

UNLABELLED 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.

BLAST++ : A Tool for BLASTing Queries in Batches

Partition-Based Approach to Processing Batches of Frequent Itemset Queries

We consider the problem of optimizing processing of batches of frequent itemset queries. The problem is a particular case of multiple-query optimization, where the goal is to minimize the total execution time of the set of queries. We propose an algorithm that is a combination of the Mine Merge method, previously proposed for processing of batches of frequent itemset queries, and the Partition ...

MPBLAST : improved BLAST performance with multiplexed queries

UNLABELLED We have developed a program, MPBLAST, that increases the throughput of batch BLASTN searches by multiplexing (concatenating) query sequences and thereby reducing the number of actual database searches performed. Throughput was observed to increase in reciprocal proportion to the component sequence length. For sequencing read-sized queries of 500 bp, an order of magnitude speed-up was...

Blasting injuries in surface mining with emphasis on flyrock and blast area security.

PROBLEM Blasting is a hazardous component of surface mining. Serious injuries and fatalities result from improper judgment or practice during rock blasting. This paper describes several fatal injury case studies, analyzes causative factors, and emphasizes preventive measures. METHOD This study examines publications by MSHA, USGS, and other authors. The primary source of information was MSHA's...
