Perhaps you should try some spelling variations:
information propagation » information presentation, information organization
propagation based » propagation case, propagation a, propagation due
based extension » based extraction
array probing » arrays probing, assay probing, array profiling
array arcing » array forming, array sharing, array using

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 based extension ((((array arcing) OR (array probing))) or (array format))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information propagation based extension ((((array arcing) OR (array probing))) OR (array format)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "information propagation based extension ((((array arcing) OR (array probing))) or (array format))".
• Adding a wildcard symbol may retrieve word variants: information propagation based extension ((((array arcing) OR (array probing))) or (array format))*.
