Perhaps you should try some spelling variations:
surface diffusion » state diffusion
information time » information theme, information tools
arrays probing » array probing, rays probing, arrays producing
time surface » timber surface, line surface, ice surface
array string » array strong, arrays strings, array sharing
array using » arrays using

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 time surface diffusion ((array using) OR (((array string) OR (arrays probing))))~.
• Adding a wildcard symbol may retrieve word variants: information time surface diffusion ((array using) or (((array string) or (arrays probing))))*.
