  • Patent number: 10470879
    Abstract: A heart valve bioprosthesis (100) and a manufacturing method thereof are provided. The heart valve bioprosthesis (100) comprises: a support frame (1), valve leaflets (2) and a valve auxiliary structure. The valve leaflets (2) are connected to the valve auxiliary structure, the valve auxiliary structure is connected to the support frame (1). Both the valve leaflets (2) and the valve auxiliary structure are made of biological tissues. The support frame (1) is formed as a single component with an elastic material, and the valve auxiliary structure is preset with suturing marks. The heart valve bioprosthesis improves the biocompatibility with the human body, reduces the total height of the valve, shortens the suturing time, and decreases the possibility of thrombus or bacterial attachment thereto. In addition, the heart valve bioprosthesis is made by a simple process, exhibit excellent compliance with the cardiac tissue, and has a prolonged service life.

  • Publication number: 20150261576
    Abstract: Systems and techniques are described for optimizing memory sharing. A described technique includes grouping virtual machines (VMs) into groups including a first group; initializing a first VM in the first group, wherein initializing the first VM includes identifying, for each of one or more first memory pages for the first VM, a respective base address for storing the first memory page using an address randomization technique, and storing, for each of the one or more first memory pages, data associating the first memory page with the respective base address for the first group, and initializing a second VM while the first VM is active, wherein initializing the second VM includes determining that the second VM is a member of the first group, and in response, storing one or more second memory pages for the second VM using the respective base addresses stored for the first group.

  • Publication number: 20110137939
    Abstract: Using the way of destruct, the complex system is split into several different qualitative elements (the definition of indicator, the definition of database, the definition of scheduling, the definition of check way, etc.). Each element has its special concept. Combing different elements organically, a completely certain meaning indicator-checked incident is produced, and it is possible to finish the expected indicator-checked task flexibly. In the case of the check fails, due to the pre-warning it is possible to perform the manual intervention in time.
