Improved photoetching fabrication method
Photoetching method producing well-defined lines with minimum undercutting was developed for etching coolant passages in nickel sheet. Phosphate coating is applied over conventional silver plate maskant and phosphoric acid solution is used to remove silver maskant. Phosphoric acid prevents etching of silver edges and mask has sharply-defined lines
On a nonhierarchical version of the generalized random energy model
We introduce a natural nonhierarchical version of Derrida's generalized
random energy model. We prove that, in the thermodynamical limit, the free
energy is the same as that of a suitably constructed GREM.Comment: Published at http://dx.doi.org/10.1214/105051605000000665 in the
