Perhaps you should try some spelling variations:
composition concurrent » computation concurrent, compression concurrent, composition coabsorbent
concurrent programming » constraint programming, concurrent programs
functions composition » function composition, functional composition, function decomposition
microarray profiling » microrna profiling
array string » array strong, arrays strings, array sharing

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "functions composition concurrent programming ((array string) OR (microarray profiling))~".
• Adding a wildcard symbol may retrieve word variants: functions composition concurrent programming ((array string) OR (microarray profiling))*.
