Perhaps you should try some spelling variations:
based preprocessing » based processing (Expand search), and preprocessing (Expand search), data preprocessing (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their disease » the disease (Expand search), hair diseases (Expand search)
disease based » disease caused (Expand search), disease case (Expand search), diseases caused (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (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.

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