Abstract: A loading and unloading system, a carrying boat, and a suction cup assembly are provided. The loading and unloading system includes a carrying boat, a cassette, and a suction cup assembly. The suction cup assembly is configured to transfer wafers between the carrying boat and the cassette. The carrying boat includes multiple stations defined along a first direction. Each station is configured to accommodate M wafers. The cassette is configured to accommodate N wafers. M and N are not equal.

Abstract: A turbulence-enhanced liquid-solid friction nano power generation device is provided, including multiple power generation cores connected in parallel. Each of the power generation cores includes an outer tube, a friction liquid, external friction electrodes, internal turbulators and internal friction electrodes. When the power generation cores undergo a swing motion, the friction liquid inside the outer tube rubs against an inner wall of the outer tube and an outer membrane of each of the internal turbulators to generate charges; and the charges are transferred based on the external friction electrodes and the internal friction electrodes, and an alternating current is generated and is led out through an external wire.

Abstract: A computer-implemented method includes determining a quantity of reserved resources that need to be reserved in one node. Nodes in which quantities of current remaining resources are less than a quantity of reserved resources are determined. For each determined node, calculating a total quantity of resources occupied by allocated service requests in the node and determining whether the node is capable of satisfying the quantity of reserved resources. If yes, marking the node as a migratable node. One migrating node is selected from migratable nodes and corresponding M allocated service requests are migrated to at least one other node. Resources occupied by the M allocated service requests are released, where M satisfies a condition that after the resources occupied by the M allocated service requests are released, a quantity of remaining resources in the migrating node is not less than the quantity of reserved resources.

Abstract: Provided is helicase BCH1X, which comprises an amino acid sequence represented by SEQ ID NO: 1 or 2. Further provided are a complex structure comprising helicase BCH1X and a binding moiety used for binding to a polynucleotide, and a use thereof in the control and characterization of a polynucleotide and in single molecule nanopore sequencing.

Abstract: The present invention provides a helicase BCH2X, comprising an amino acid sequence represented by any one of SEQ ID NOs: 1-3. The present invention also provides a complex structure comprising the helicase BCH2X and a binding moiety for binding polynucleotides. The present invention also provides a use of the helicase BCH2X or the complex structure comprising same in the control and characterization of polynucleotides and single-molecule nanopore sequencing.

Abstract: This specification discloses resource scheduling methods and apparatuses, electronic devices. The resource scheduling method includes following: estimated resource consumption data of a target container group in a plurality of time periods is determined in response to a resource application request of the target container group, resource amount data of each of a plurality of cluster nodes in the plurality of time periods is obtained, and the target container group is scheduled to at least one of the plurality of cluster nodes based on the estimated resource consumption data and the resource amount data. It can be seen that in this specification, different resource amounts can be allocated to the target container group in different time periods, and the target container group can fully use resources allocated to the target container group in each time period during running, thereby reducing the waste of cluster resources.

Abstract: Embodiments of this specification provide batch scheduling-based application scheduling methods, apparatuses, and systems. In the batch scheduling-based application scheduling method, an application scheduling request is received from a client, where the application scheduling request includes description information used to indicate a chain invoking relationship between applications to be scheduled; the applications to be scheduled are grouped into at least one scheduling object group based on the chain invoking relationship, where applications to be scheduled that are located in the same scheduling object group have the same chain invoking relationship; and the applications to be scheduled are scheduled to a target node by using the scheduling object group as a unit.
