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

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: (("neuron femoral artificial neural networks") OR ("neural model artificial neural network"))~.
• Removing quotes may allow a broader search: (( neuron femoral artificial neural networks ) or ( neural model artificial neural network ))~.
• Adding a wildcard symbol may retrieve word variants: (("neuron femoral artificial neural networks") or ("neural model artificial neural network"))*.
