Perhaps you should try some spelling variations:
decrease processes » disease processes (Expand search), defense processes (Expand search), decay processes (Expand search)
perfusion patterns » regression patterns (Expand search), recursion patterns (Expand search), perfusion after (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decrease sucrose (Expand search)
python perfusion » on perfusion (Expand search), pet perfusion (Expand search), non perfusion (Expand search)
patterns python » patterns patos (Expand search)

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

• Removing quotes may allow a broader search: (( decrease _ decrease decrease processes ) OR ( python perfusion patterns python programming ))~.
