Perhaps you should try some spelling variations:
decrease invariant » decreases ovarian (Expand search), decreased ovarian (Expand search)
invariant objects » invariant sets (Expand search), invariant moments (Expand search), invariant tests (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (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), to decrease (Expand search)
decrease l » decrease il (Expand search), decrease _ (Expand search), decrease β (Expand search)
l increase » l increases (Expand search), _ increase (Expand search), 3 increase (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 l increase during decrease ) OR ( decrease rate decrease invariant objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease l increase during decrease ) OR ( decrease rate decrease invariant objects ))*.
