Perhaps you should try some spelling variations:
"parallel acceleration" » "particle acceleration", "parallel generation", "parallel application"
"lattices accelerated" » "matrices accelerated", "particles accelerated", "devices accelerated"
"particle accelerators" » "article accelerators", "particle accelerator", "particle accelerate", "particle accelerating"

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: (("particle accelerators") OR ((("lattices accelerated") OR ("parallel acceleration")))).
• Removing quotes may allow a broader search: (( particle accelerators ) or ((( lattices accelerated ) or ( parallel acceleration )))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerators") or ((("lattices accelerated") or ("parallel acceleration"))))*.
