Perhaps you should try some spelling variations:
"defended cross-correlations" » "defended from-correlations", "extended cross-correlations", "defended case-correlations"
"defense cross-correlations" » "defense cost-correlations", "dense cross-correlations", "defense actors-correlations"

Try widening your search to All Fields.

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("defended cross-correlations") OR ("detrended cross-correlations"))) OR ("defense cross-correlations")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"defended cross-correlations\") OR (\"detrended cross-correlations\"))) or (\"defense cross-correlations\"))".
• Removing quotes may allow a broader search: (((( defended cross-correlations ) OR ( detrended cross-correlations ))) or ( defense cross-correlations )).
• Adding a wildcard symbol may retrieve word variants: (((("defended cross-correlations") OR ("detrended cross-correlations"))) or ("defense cross-correlations"))*.
