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

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