Perhaps you should try some spelling variations:
significant deviation » significant variation (Expand Search), significant elevation (Expand Search), significant variations (Expand Search)
deviation paths » mediation path (Expand Search), deviation data (Expand Search), deviation values (Expand Search)
step decrease » sizes decrease (Expand Search), teer decrease (Expand Search), we decrease (Expand Search)
a decrease » _ decrease (Expand Search), _ decreased (Expand Search), _ decreases (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: "(( significant ((step decrease) OR (a decrease)) ) OR ( significant deviation paths ))~".
• Adding a wildcard symbol may retrieve word variants: (( significant ((step decrease) OR (a decrease)) ) OR ( significant deviation paths ))*.
