  • Publication number: 20200183889
    Abstract: Embodiments of the present disclosure provide techniques for efficiently and accurately performing propagation of search-head specific configuration customizations across multiple individual configuration files of search heads of a cluster for a consistent user experience. The cluster of search heads may be synchronized such that the search heads operate to receive the configuration or knowledge object customizations from one or more clients from a central or lead search head. To reduce the amount of data that is transferred during propagation, the list of configuration or knowledge object customizations maintained in each search head is filtered from the list of the lead search head until a divergence point is determined. Once determined and communicated to the lead search head, the lead search head sends the configuration and knowledge object customization data that is absent from the internal list of the member search head.

  • Publication number: 20200097621
    Abstract: Pattern centric process control is disclosed. A layout of a semiconductor chip is decomposed into a plurality of intended circuit layout patterns. For the plurality of intended circuit layout patterns, a corresponding plurality of sets of fabrication risk assessments corresponding to respective ones of a plurality of sources is determined. Determining a set of fabrication risk assessments for an intended circuit layout pattern comprises determining fabrication risk assessments based at least in part on: simulation of the intended circuit layout pattern, statistical analysis of the intended circuit layout pattern, and evaluation of empirical data associated with a printed circuit layout pattern. A scoring formula is applied based at least in part on the sets of fabrication risk assessments to obtain a plurality of overall fabrication risk assessments for respective ones of the plurality of intended circuit layout patterns.

  • Publication number: 20200029033
    Abstract: The invention relates to a pixel unit of a dynamic vision sensor. The pixel unit comprises a pixel photosensitive circuit for detecting an optical signal, and generating and outputting an electrical signal when a change in the optical signal is detected; and a communication circuit connected to the pixel photosensitive circuit; and further comprises: a neighborhood denoising circuit connected to the pixel photosensitive circuit, the communication circuit and other pixel units in four neighborhoods, for controlling—whether the communication circuit outputs the electrical signal. In embodiments of the invention, when a pixel unit executes a response trigger event for an optical signal, and if at least three of the pixel units in the four neighborhoods are in a non-response state, the pixel unit does not respond, thereby effectively avoiding the generation of isolated noise, and having beneficial effects of a fast processing speed and a high denoising accuracy.

  • Patent number: 10214583
    Abstract: Antibodies that are agonists of sodium pump (Na+/K+ ATPase; NKA) activity are provided. In particular, antibodies that specifically bind epitopes on the beta-1 (?1) subunit of NKA are disclosed. These antibodies have the ability to increase the activity of the catalytic alpha subunit of NKA upon ?1 subunit binding. Due to their activity, the antibodies also have the ability to trigger a positive inotropic effect in cardiac tissues (i.e., increase cardiac contraction). The present invention thus includes, but is not limited to, NKA ?1 subunit peptide epitopes, antibodies that specifically bind the epitopes, methods of increasing NKA activity and cardiac contraction through administration of the peptide vaccines or the antibodies, and methods of treating and/or preventing heart disease through administration of the peptides or the antibodies.

  • Publication number: 20180360933
    Abstract: Antibodies binding to sites on the alpha-subunit of the (Na++K+)-ATPase increase cardiac contraction of both ventricular myocytes and mouse heart. In particular, antibodies binding to the RSATEEEPPNDD (SEQ ID NO: 1) or DVEDSYGQQWTYEQR (SEQ ID NO: 2) peptides (or isoforms/derivatives thereof) of the alpha-subunit of the (Na++K+)-ATPase, have been found to be highly inotropic.
