Perhaps you should try some spelling variations:
"neural femoral artificial neural networks" » "neural real artificial neural networks", "neural femoral artificial neural network"
"nerf model artificial neural networks" » "nerf real artificial neural networks", "nerf model artificial neural network", "new model artificial neural networks", "neural model artificial neural networks", "neuron model 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: (("nerf model artificial neural networks") or ("neural femoral artificial neural networks"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("nerf model artificial neural networks") OR ("neural femoral artificial neural networks")).
• Removing quotes may allow a broader search: (( nerf model artificial neural networks ) or ( neural femoral artificial neural networks )).
• Adding a wildcard symbol may retrieve word variants: (("nerf model artificial neural networks") or ("neural femoral artificial neural networks"))*.
