  • Patent number: 9256682
    Abstract: An entity may be related to multiple related entities by one or more properties, and the entity may also be associated with one or more entity types. A system for providing sorted results may include identifying the entity, related entities, and types. The system may also determine related entity scores for each respective related entity, relative to the entity. For each property, the related entity scores of the related entities related to the entity by that property are combined to generate a property score. The properties are then sorted based on their property scores. The sorting may occur for properties associated with an entity type, and sorted search results may be provided as output for one or more entity types of interest.

  • Patent number: 9195790
    Abstract: Techniques for statistical formal activity analysis with consideration of temporal and/or spatial correlations are described herein. According to one embodiment, a machine-implemented method for circuit analysis comprises unrolling a sequential circuit having a feedback loop into a plurality of unrolled circuits and introducing a spatial correlation via an encoding circuit coupled to the plurality of unrolled circuits for an activity analysis of the sequential circuit, the spatial correlation representing a dependency relationship between logic states of an input and logic states of other signals.

  • Patent number: 8656327
    Abstract: Techniques for statistical formal activity analysis with consideration of temporal and/or spatial correlations are described herein. According to one embodiment, a sequential circuit having a feedback loop is unrolled into multiple unrolled circuits, where the sequential circuit is represented by a finite state machine (FSM). A temporal correlation is introduced to each of the unrolled circuits via a correlation network for an activity analysis of the sequential circuit. The temporal correlation represents a dependency relationship between a current logic state of a signal and a previous logic state of the signal. Other methods and apparatuses are also described.

  • Publication number: 20090083866
    Abstract: The invention relates to non-human transgenic animals expressing bioluminescent markers The invention provides a transgenic mouse whose genome comprises a nucleotide sequence encoding lucif erase, operably linked to murine control sequences whereby the lucif erase is expressed in all cells. Administration of a luciferin substrate to the mouse results in bioluminescence. The control sequence is the Rosa 26 promoter.
