  • Publication number: 20240101714
    Abstract: Described herein are methods for the efficient production of a heteromultimeric protein, such as a bispecific antibody. Heteromultimeric proteins may be capable of specifically binding to more than one target molecule or different epitopes on a single target molecule. The methods modulate parameters to improve assembly of the heteromultimeric proteins at higher yield and efficiency than otherwise possible. Also described are compositions comprising a hinge-containing polypeptide, such as a half-antibody.

  • Patent number: 8161439
    Abstract: Method and apparatus for processing assertions in assertion-based verification of a logic design are described. One example relates to processing an assertion during verification of a logic design. An evaluation engine is generated that encodes, using a non-deterministic finite automata (NFA) model, temporal behavior of the logic design required by the assertion for a single attempt to evaluate the assertion. The evaluation engine is implemented in first reconfigurable hardware. The logic design is simulated over a plurality of clock events. Attempts to evaluate the assertion by the evaluation engine are preformed sequentially based on input stimuli obtained from the logic design during simulation thereof. Each of the attempts results in one of the assertion passing, the assertion failing, or the assertion requiring further evaluation.

  • Publication number: 20070226693
    Abstract: A method of preparing a certification project plan for certifying compliance for a mobile platform project with pre-defined regulations is provided. The method includes defining the project in a software system and defining a certification plan for the project in the software system. The method also includes selecting authorized representatives based on their delegated authorities from a database to carry out the certification plan. The method can include verifying the completion of the certification plan and generating at least one document to indicate that the mobile platform is in compliance based on the completed certification plan.
