Perhaps you should try some spelling variations:
information propagation » information presentation, information organization
hat dimensions » hat dimension, data dimensions, head dimensions
et dimensions » new dimensions, pit dimensions, _ dimensions
using like » using line, using lime, using live
using life » using linear

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 ((et dimensions) OR (hat dimensions)) ((using like) OR (using life))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information propagation ((et dimensions) or (hat dimensions)) ((using like) OR (using life))~".
• Adding a wildcard symbol may retrieve word variants: information propagation ((et dimensions) or (hat dimensions)) ((using like) OR (using life))*.
