  • Patent number: 12417179
    Abstract: Adaptive system probe action to minimize input/output dirty data transfers is described. In one or more implementations, a system includes a processor, a memory configured to store data, and a cache configured to store a portion of the data stored in the memory for execution by the processor. The system also includes a cache coherence controller including a cache line history. The cache coherence controller is configured detect a direct memory access request from an input/output device. The direct memory access request is associated with an input/output operation involving the data. The cache coherence controller is further configured to identify a cache line associated with the direct memory access request, and, in response to the cache line history including a dirty data transfer record corresponding to the cache line, selectively send a probe to the cache based on a state of the cache line.

  • Publication number: 20240299510
    Abstract: The present disclosure describes the grafting of epitope residues from human PCSK9 to non-human PCSK9 or PCSK9 structural homologs and elimination of 9-mers oligopeptides that are found in human protein to reduce self-targeting response. Anti-genicity of the epitope-scaffold constructs was demonstrated toward anti-human PCSK9 antibodies. similar to wild type human PCSK9. It was shown that disclosed PCSK9 immunogens could significantly reduce LDL and cholesterol levels in immunized mice.
