Quadratic Tangles in Planar Algebras
In planar algebras, we show how to project certain simple "quadratic" tangles
onto the linear space spanned by "linear" and "constant" tangles. We obtain
some corollaries about the principal graphs and annular structure of
subfactors
Capillary flow weld-bonding
The invention of a weld-bonding technique for titanium plates was described. This involves fastening at least two plates of titanium together using spot-welding and applying a bead of adhesive along the edge of the resistance spot-welded joint which upon heating, flows and fills the separation between the joint components
