Abstract: An electrode piece, a rolled core and a battery, where the electrode piece includes a current collector and an active substance layer; the electrode piece has a single-sided area and a double-sided area, the single-sided area is located on a side of the electrode piece along a length direction thereof, a surface of one side of the current collector in the single-sided area is covered with the active substance layer, while surfaces of both sides of the current collector in the double-sided area are covered with the active substance layer; and multiple tabs protrude from one side of the electrode piece along a width direction thereof, and are spaced apart; in the single-sided area, an anti-rolling strip is provided on a surface of a side of the current collector not covered by the active substance layer, and is disposed on the same side as the tabs.

Abstract: Disclosed are an isolation method for a high-performance computer system, and a high-performance computer system. The isolation method comprises node-level isolation performed. The node-level isolation comprises: configuring a routing table for each computing node, and configuring, in the routing table, valid routing information for computing node pairs; when any one source computing node needs to communicate with a target computing node, determining, by lookup, whether valid routing information exists between the source computing node and the target computing node according to the configured routing table; if so, allowing the source computing node to communicate with the target computing node; otherwise, forbidding the source computing node from communicating with the target computing node.

Abstract: A server system receives, from a first user device through a first network carrier, a request to access content. One or more characteristics of the first network carrier are determined from the request, including at least one of an identity of the first network carrier and a network type of the first network carrier. The determining includes performing a look-up using information from the request. Furthermore, the server system performs at least one of: (1) storing the determined one or more characteristics in association with the first user device in a first data structure, where the first data structure specifies, for multiple user devices, at least an identity of associated network carriers and a network type; and (2) providing access to requested content, which includes content customized based on the determined one or more characteristics.

Abstract: An application under testing is initiated to record reactions of the application responsive to user input. If it is determined that the user input triggers an external process initiated by another program such that the other program precludes recording of the triggered reactions of the external process, an association with the external process is obtained.
