Perhaps you should try some spelling variations:
rescattering effect » scattering effects (Expand search), feathering effect (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)
decrease l » decrease il (Expand search), decrease β (Expand search), decrease low (Expand search)
l decrease » α decrease (Expand search), to decrease (Expand search), or decrease (Expand search)

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

• Removing quotes may allow a broader search: (( decrease l decrease _ decrease ) OR ( decrease toc decrease rescattering effect ))~.
