  • Publication number: 20240072254
    Abstract: Disclosed are a positive electrode plate and a battery. A relationship is established between a thickness of an electrode plate, distribution of lithium cobalt oxide with a structure of different contents of element aluminum, and full battery cycling performance. That is, based on a thickness of the electrode plate, lithium cobalt oxide with an appropriate content of the element aluminum is selected, and distribution in a thickness direction of the positive electrode plate is changed, so that the content of Al in the thickness direction of the electrode plate generally presents a distribution trend of less content of Al in a bottom layer and more content of Al in a top layer. In this way, a problem of deterioration of high temperature cycling of a lithium-ion battery due to decreased structural stability of existing lithium cobalt oxide may be solved.

  • Publication number: 20240014722
    Abstract: In a rotating magnetic field-variable pyramid energy cabin, shielding plate permanent magnets are disposed on inner surfaces of three triangular shielding plates forming a pyramid shape, to form a stable magnetic field in the triangular shielding plates. A top rotating magnet is disposed at a top of the triangular shielding plates. A bottom rotating magnet is disposed below a seat. The magnetic field in the triangular shielding plates is rotated, to enable a vortex in turbulence of magnetic lines of force to generate a torsion field. The torque of the torsion field changes the spin states of electrons and atomic cores in a hypoxic microfield in the body of a patient, to arrange the electrons and atomic cores in a uniform magnetic field direction. The magnetic actuation of the electrons and atomic cores can make the microfield environment serialized and orderly and increase the negentropy.

  • Patent number: 11843663
    Abstract: A logical clock is implemented in networked nodes. Messages between nodes can include either a scalar timestamp or a vector timestamp. The scalar timestamp leads to an overhead reduction, and nodes can select whether to send a scalar or vector timestamp depending on requirements. Message recipients update their logical clock vector differently depending on whether the scalar or vector timestamp is received. Applications to multi-master databases are also provided. The clock conforms to Lamport clock requirements when the scalar timestamp is sent, and conforms to both Lamport and vector clock requirements when the vector timestamp is sent.

  • Patent number: 11714794
    Abstract: The present disclosure provides a method of reading data maintained in a tree data structure, such as B+ tree, using near data processing (NDP) in a cloud native database. According to embodiments, a desired LSN will be used in NDP page reads on the master computing node (e.g. master SQL node). When the master computing node (e.g. master SQL node) reads the regular page, the maximum desired LSN (e.g. the latest page version number) for that regular page will be used. Embodiments use features of the desired LSN and page locking, wherein correct versions of pages can be obtained by using the desired LSN associated with a page, in combination with page locking, and can enable the reading of a consistent tree structure and achieve good read/write concurrency.

  • Patent number: 11657066
    Abstract: Methods, processing units, and computer-readable media in a cloud-based database are described. Redo log records are applied to a page at a database replica only when an updated version of the page is requested at the database replica. A log cache may be used by a replica node of the database to track recent redo log records applicable to a given page. The recent redo log records stored in the log cache may be applied to update the page on-demand when an updated version of the page is requested. By applying only the redo log records applicable to pages that are currently being requested, processing resources may be used only to generate pages that are currently required. Methods for registering redo log records into the log cache by the master or replica server are also described.
