  • Patent number: 8707238
    Abstract: The present disclosure relates to a method of routing probe pads to micro-bumps of an interposer. An interposer is provided having target micro-bumps and probe pads. The probe pads are initially unassigned. Target micro-bump locations and probe pad locations are obtained. Possible route assignments from the probe pads to the target micro-bumps are obtained. Costs are developed for the possible route assignments at least partially according to the target micro-bump locations and the probe pad locations. Final assignments are selected from the possible assignments according to the costs.

  • Publication number: 20120263676
    Abstract: The present invention relates to compositions, methods and kits based on the ADAM-mediated cleavage of Her-2. The present invention also relates to treatments for cancer, and in particular, breast cancer, by modulating the ADAM-mediated cleavage of Her-2. Further, the invention relates to compositions, methods and kits based on the surprising synergistic effect between inhibition of Her-2 cleavage by an ADAM and certain cytostatic (e.g., Herceptin) and cytotoxic (e.g., Taxol) compounds in, among other things, inhibiting tumor cell proliferation and inducing cell death. Additionally, the invention relates to novel variants of ADAM15, designated ADAM15 variant 1 and ADAM15 variant 2, now identified and isolated.

  • Patent number: 4451178
    Abstract: The method of diverting a lava flow including the steps of positioning for illing a vessel, explosive under high temperature and pressure, at least partially filling the vessel with a nonflammable composition, stable at normal temperature and convertible to gas under high temperature allowing room within the vessel for expansion of the composition if frozen, tightly sealing the vessel to prevent loss of the composition, positioning in a volcanic region in the normal expected path of a lava flow in a specific area, which will cause the lava flow to be diverted from certain geographic locations upon explosion of the vessel, whereby when a lava flow occurs in the volcanic region and flows over the vessel, the vessel will heat up to temperatures in excess of 1000.degree. F.
