Perhaps you should try some spelling variations:
functions computational » functions computation, function computation, directions computational
complexity dimensions » complex dimensions, complexity bisections, community dimension
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 computational complexity dimensions ((microarray profiling) OR (array string))~".
• Adding a wildcard symbol may retrieve word variants: functions computational complexity dimensions ((microarray profiling) OR (array string))*.
