Perhaps you should try some spelling variations:
"partially accelerated" » "partially correlated", "partially integrated", "naturally accelerate"
"particles accelerated" » "particles acceleration", "lattices accelerated", "particle acceleraton"
"parallel acceleration" » "particle acceleration", "parallel generation", "parallel application"
"particle accelerator" » "particle acceleration"
"particle accelerators" » "particle accelerations", "particle accelerate", "particle accelerating"
"particle accelerated" » "particle acceleraton", "particle acceleration", "practice accelerated"

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 accelerator") OR ((("particle accelerators") OR ((("particle accelerated") OR ((((("particles accelerated") OR ("partially accelerated"))) OR ("parallel acceleration")))))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"particle accelerator\") or (((\"particle accelerators\") or (((\"particle accelerated\") or (((((\"particles accelerated\") OR (\"partially accelerated\"))) or (\"parallel acceleration\"))))))))".
• Removing quotes may allow a broader search: (( particle accelerator ) or ((( particle accelerators ) or ((( particle accelerated ) or ((((( particles accelerated ) OR ( partially accelerated ))) or ( parallel acceleration )))))))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((("particle accelerators") or ((("particle accelerated") or ((((("particles accelerated") OR ("partially accelerated"))) or ("parallel acceleration"))))))))*.
