Perhaps you should try some spelling variations:
"learning-based 3d implantation technique" » "learning-based 3d imputation techniques", "learning-based 3d inhalation technique", "learning-based _ implantation technique", "learning-based co implantation technique", "learning-based k implantation technique"
"learning-based 3D floatation technique" » "learning-based 3D inhalation technique", "learning-based 3D imputation techniques", "learning-based 3D truncation technique"
3d floatation » _ floatation

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("learning-based 3D floatation technique") OR ("learning-based 3d implantation technique"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"learning-based 3D floatation technique\") OR (\"learning-based 3d implantation technique\"))*".
• Removing quotes may allow a broader search: (( learning-based 3D floatation technique ) OR ( learning-based 3d implantation technique ))*.
