Perhaps you should try some spelling variations:
field progression » and progression (Expand search), cycle progression (Expand search), rapid progression (Expand search)
decreased field » decreased feed (Expand search), decreases yield (Expand search), decreased il (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease the (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (Expand search)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not 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 in decreased field progression ) OR ( decrease toc decrease with decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decreased field progression ) OR ( decrease toc decrease with decrease ))*.
