Perhaps you should try some spelling variations:
information complexity » information computing
complexity theoretical » complexity theoretic, complexes theoretical, comet theoretical
theoretical diffusion » theoretical discussion, theoretical discussions, theoretical dimensions
microarray profiling » microrna profiling
arrays profiling » array profiling, arrays probing, arrays producing

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 complexity theoretical diffusion ((microarray profiling) OR (arrays profiling))~.
• Adding a wildcard symbol may retrieve word variants: information complexity theoretical diffusion ((microarray profiling) or (arrays profiling))*.
