Perhaps you should try some spelling variations:
information propagation » information presentation, information organization
propagation dark » propagation data, propagation early, propagation aware
dark dimensions » task dimensions, d dimensions, all dimensions
causal role » causes role, causal model, causal force
viruses co » viruses a, viruses from

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: information propagation dark dimensions ((causal role) OR (((viruses co) OR (viruses _))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information propagation dark dimensions ((causal role) or (((viruses co) OR (viruses _))))~".
• Adding a wildcard symbol may retrieve word variants: information propagation dark dimensions ((causal role) or (((viruses co) OR (viruses _))))*.
