Perhaps you should try some spelling variations:
"advanced mathematical sciences" » "advanced mathematics sciences", "advanced mathematical geosciencess", "advanced mathematical finances"
"applied mathematical science" » "applied mathematics science", "appendix mathematical science", "applied mathematical geosciences", "applied mathematical finance"
"based mathematical science" » "based mathematics science", "based mathematical geosciences", "based mathematical finance", "basic mathematical science"

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: (((("applied mathematical science") OR ("based mathematical science"))) OR ("advanced mathematical sciences")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"applied mathematical science\") OR (\"based mathematical science\"))) or (\"advanced mathematical sciences\"))".
• Removing quotes may allow a broader search: (((( applied mathematical science ) OR ( based mathematical science ))) or ( advanced mathematical sciences )).
• Adding a wildcard symbol may retrieve word variants: (((("applied mathematical science") OR ("based mathematical science"))) or ("advanced mathematical sciences"))*.
