Perhaps you should try some spelling variations:
decrease emitter » decrease litter (Expand search), decrease elicited (Expand search), decrease after (Expand search)
emitter patterns » motor patterns (Expand search), weather patterns (Expand search), merger patterns (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), and decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 rate decrease _ decrease ) OR ( decrease to decrease emitter patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rate decrease _ decrease ) OR ( decrease to decrease emitter patterns ))*.
