Perhaps you should try some spelling variations:
network synthesis » network systems
health incidence » health incident, health science, health insurance
networks systems » network systems, networks system, networked systems
health evidence » health science
death incidence » growth incidence, dengue incidence, graphs incidence
path incidence » high incidence, a incidence, age incidence
systems report » system report, systems support, systems recent
guide network » guided network, side network, wide network
health guide » health guido, earth guide, health grid

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) OR (path incidence))) OR (health evidence))) OR (death incidence)) networks systems report ) OR ( health guide network synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((((((health incidence) OR (path incidence))) or (health evidence))) or (death incidence)) networks systems report ) or ( health guide network synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( ((((((health incidence) OR (path incidence))) or (health evidence))) or (death incidence)) networks systems report ) or ( health guide network synthesis report ))*.
