Talvez debería tentar con algunhas variantes ortográficas:
informatics group » informatics great, informatics from
state diffusion » surface diffusion
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
group state » groups state, group started, ground state

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: informatics group state diffusion ((((array imaging) OR (array string))) OR (array format))~.
• Adding a wildcard symbol may retrieve word variants: informatics group state diffusion ((((array imaging) or (array string))) or (array format))*.
