  • Publication number: 20140212410
    Abstract: A method for transmission network control, the transmission network being configured for use in providing electricity from a generator to an end user, the method including receiving a sensitivity parameter, identifying a switchable set of switches within the transmission network using the sensitivity parameter, determining a candidate switch from the switchable set to change a corresponding state, wherein the state can be changed from open to closed and closed to open, determining a proposed change of state of the candidate switch, updating an optimal power flow (OPF) problem as a function of the candidate switch and the proposed change of state, determining and storing in a memory a solution to the updated OPF problem, generating an updated sensitivity parameter based on the stored solution to the updated OPF problem, and determining, using the updated sensitivity parameter, if the stored solution to the updated OPF problem meets a predetermined criterion.

  • Patent number: 8445229
    Abstract: The invention provides methods for generating high titers of high-affinity antibodies from hybridoma cells produced by fusing myeloma cells with in vitro immunized donor cells. The hybridoma cells or mammalian expression cells with cloned antibody genes from the hybridomas producing the high-affinity antibodies may be mismatch repair defective due to defects of endogenous mismatch repair subunits of through expression of a dominant negative allele of a mismatch repair gene which allows the hybridoma cell to be hypermutable, may be rendered hypermutable by chemical means, or may be naturally mismatch repair deficient. High-affinity antibodies and high titer producer cells producing antibodies may be prepared by the methods of the invention.
