Perhaps you should try some spelling variations:
"neurons femoral artificial neural networks" » "neurons model artificial neural networks", "neurons real artificial neural networks"
"neutron can artificial neural network" » "neutron real artificial neural network", "neutron _ artificial neural network", "neutron star artificial neural network"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("neutron can artificial neural network") or ("neurons femoral artificial neural networks"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("neutron can artificial neural network") OR ("neurons femoral artificial neural networks"))*.
• Removing quotes may allow a broader search: (( neutron can artificial neural network ) or ( neurons femoral artificial neural networks ))*.
