Talvez debería tentar con algunhas variantes ortográficas:
information propagation » information presentation, information organization
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing

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

• Performing a fuzzy search may retrieve terms with similar spellings: information propagation _ dimensions ((array string) or (((array arcing) or (array imaging))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information propagation _ dimensions ((array string) OR (((array arcing) OR (array imaging)))).
• Adding a wildcard symbol may retrieve word variants: information propagation _ dimensions ((array string) or (((array arcing) or (array imaging))))*.
