Perhaps you should try some spelling variations:
the preprocessing » the processing (Expand search), their processing (Expand search), image preprocessing (Expand search)
decrease rapidly » disease rapidly (Expand search), decrease lipid (Expand search)
rapidly decrease » rapid decrease (Expand search), rapid increase (Expand search), taping decrease (Expand search)
decrease the » decreases the (Expand search), decrease of (Expand search)
decrease and » decreases and (Expand search), decrease of (Expand search), decrease _ (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (Expand search)

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: (( decrease rapidly decrease the preprocessing ) OR ( decrease AND decrease in decreased ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease rapidly decrease the preprocessing ) OR ( decrease and decrease in decreased ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rapidly decrease the preprocessing ) OR ( decrease and decrease in decreased ))*.
