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

Try widening your search to All Fields.

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 networks") or ("neural model artificial neural network"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("neutron can artificial neural networks") OR ("neural model artificial neural network")).
• Removing quotes may allow a broader search: (( neutron can artificial neural networks ) or ( neural model artificial neural network )).
• Adding a wildcard symbol may retrieve word variants: (("neutron can artificial neural networks") or ("neural model artificial neural network"))*.
