Perhaps you should try some spelling variations:
communicative functions » communication foundations
hash extraction » phase extraction, mesh extraction, fast extraction
array profiling » array processing, microarray profiling
functions hash » functions how
array string » array strong, arrays strings, array sharing
arrays ang » arrays a

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: "communicative functions hash extraction ((((array string) OR (array profiling))) OR (arrays ang))~".
• Adding a wildcard symbol may retrieve word variants: communicative functions hash extraction ((((array string) OR (array profiling))) OR (arrays ang))*.
