Perhaps you should try some spelling variations:
akt preprocessing » and preprocessing (Expand search), data preprocessing (Expand search), and reprocessing (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
decrease akt » decrease and (Expand search), decrease after (Expand search), decrease with (Expand search)
decrease at » decrease and (Expand search), decrease in (Expand search), decrease of (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)

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

• Removing quotes may allow a broader search: (( decrease the decrease akt preprocessing ) OR ( decrease at decrease AND decrease ))~.
