  • Publication number: 20210040153
    Abstract: The present invention relates to the field of virology, and specifically discloses a short peptide having a dengue virus replication inhibition function and an application thereof. The amino acid sequence of the short peptide provided in the present invention is KHGHHRH, i.e. Lys-His-Gly-His-His-Arg-His (SEQ ID NO. 1). The short peptide has a high specificity affinity with NS5 and has the function of efficiently inhibiting dengue virus replication, the anti-viral effect thereof not been limited to DENV-2, but also having a significant inhibitory effect on the replication of type 1, type 3, and type 4 dengue virus. One cysteine is added to the two ends of the short peptide sequence, the short peptide being cyclised by means of the cysteines at the two ends to form a cyclic peptide. The obtained cyclic peptide strengthens the dengue virus replication inhibition function, and can be used for specific treatment of dengue virus infection.

  • Publication number: 20200356270
    Abstract: A storage system includes a management node and a plurality of storage nodes forming a redundant array of independent disks (RAID). When the management node determines that not all data in an entire stripe is updated based on a received write request, the management node sends update data chunk obtained from to-be-written data to corresponding storage node. The storage node do not directly update, based on the received update data chunks, data block stored in storage device of the storage node, but store the update data chunk into non-volatile memories (NVM) cache of the storage node and send the update data chunk to another storage node to backup. According to the data updating method, write amplification problems caused in a stripe update process can be reduced, thereby improving update performance of the storage system.

  • Patent number: 10832965
    Abstract: Integrated circuit devices include trenches in a material layer that divide the material layer into fins. With such devices, an insulator partially fills the trenches and contacts the material layer. The top surface of the insulator (e.g., the surface opposite where the insulator contacts the material layer) has a convex dome shape between at least two of the fins. The dome shape has a first thickness from (from the bottom of the trench) where the insulator contacts the fins, and a second thickness that is greater than the first thickness where the insulator is between the fins. Further, there is a maximum thickness difference between the first and second thicknesses at the midpoint between the fins (e.g., the highest point of the dome shape is at the midpoint between the fins). Also, the top surface of the first insulator has concave divots where the first insulator contacts the fins.

  • Publication number: 20200250091
    Abstract: An access request processing method is performed by a computer device that includes a processor, a dynamic random-access memory (DRAM), and a non-volatile memory (NVM). When receiving a write request, the processor may identify an object cache page according to the write request. The processor obtains the to-be-written data from a buffer according to a buffer pointer in the write request, the to-be-written data including a new data chunk to be written into the object cache page. The processor then inserts a new data node into a log chain of the object cache page, where the NVM stores data representing the log chain of the object cache page. The new data node includes information regarding the new data chunk of the object cache page. The computer device provided in this application can reduce system overheads while protecting data consistency.
