Perhaps you should try some spelling variations:
chains diffusions » chains disruptions, affine diffusions, channel diffusion
information a » information age
array probing » arrays probing, assay probing, array profiling
array string » array strong, arrays strings, array sharing
array along » arrays long, array arcing, array paving
a chains » _ chains, a chain, 2 chains

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: information a chains diffusions ((array along) or (((array string) or (array probing))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information a chains diffusions ((array along) OR (((array string) OR (array probing)))).
• Adding a wildcard symbol may retrieve word variants: information a chains diffusions ((array along) or (((array string) or (array probing))))*.
