based ap » based _ (Expand Search), based 3d (Expand Search), based co (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( linac based ap optimization algorithm ) OR ( binary basic first detection algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( linac based ap optimization algorithm ) OR ( binary basic first detection algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( linac based ap optimization algorithm ) OR ( binary basic first detection algorithm ))*.
