Perhaps you should try some spelling variations:
concurrent programming » constraint programming, concurrent programs
operations concurrent » operations current, permutations concurrent, operation current
functions operations » function operators, functions relations, functions interactions
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 operations concurrent programming ((array string) OR (microarray profiling))~".
• Adding a wildcard symbol may retrieve word variants: functions operations concurrent programming ((array string) OR (microarray profiling))*.
