Perhaps you should try some spelling variations:
"neuron femoral artificial neural network" » "neuron real artificial neural network", "neutron femoral artificial neural network", "neurons femoral artificial neural network", "neuro femoral artificial neural network"
"nerf model artificial neural networks" » "nerf real artificial neural networks", "new model artificial neural networks", "neural model artificial neural networks", "neuron model artificial neural networks"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("neuron femoral artificial neural network") OR ("nerf model artificial neural networks"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"neuron femoral artificial neural network\") OR (\"nerf model artificial neural networks\"))".
• Removing quotes may allow a broader search: (( neuron femoral artificial neural network ) OR ( nerf model artificial neural networks )).
• Adding a wildcard symbol may retrieve word variants: (("neuron femoral artificial neural network") OR ("nerf model artificial neural networks"))*.
