Talvez debería tentar con algunhas variantes ortográficas:
surface diffusion » state diffusion
information gap » information guide
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
gap surface » egfp surface, tip surface, 1a surface
