Perhaps you should try some spelling variations:
incidence networks » inference networks, influence networks, incidents network
network synthesis » network systems
science networks » science network, sciences network, sequence networks
health impedance » health importance, health temperance, head impedance

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( health ((incidence networks) OR (science networks)) synthesis report ) OR ( health impedance network synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((incidence networks) OR (science networks)) synthesis report ) or ( health impedance network synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( health ((incidence networks) OR (science networks)) synthesis report ) or ( health impedance network synthesis report ))*.
