Abstract: The present disclosure relates to a data recovery method, a storage medium, and an electronic device. The method includes: receiving a notification message sent by a computing node in a distributed graph computing system, where the notification message represents that the corresponding computing node successfully stores current checkpoint data in a persistent memory; generating a checkpoint identifier corresponding to a current checkpoint when determining that all computing nodes in the distributed graph computing system successfully store the current checkpoint data in respective persistent memories; and sending the checkpoint identifier to each computing node, so that each computing node associates the checkpoint identifier with the current checkpoint data stored in the persistent memory, and the associated current checkpoint data is used for data recovery during recovery execution before the corresponding computing node obtains a checkpoint identifier corresponding to a next checkpoint.

Abstract: Nuclear reactor cores and related systems are described herein. An example nuclear reactor core includes a plurality of fuel modules, where each of the plurality of fuel modules includes nuclear fuel; at least one fuel-module actuator mechanically coupled to at least one of the plurality of fuel modules, where the at least one fuel-module actuator is configured to rotate the at least one of the plurality of fuel modules; and at least one neutron source configured to emit neutrons and trigger a fission chain reaction in the at least one of the plurality of fuel modules.

Abstract: An earmuff and head-mounted headphones are disclosed. The earmuff comprises earmuff leather and earmuff sponge. The earmuff further comprises an earmuff airbag made of a soft rubber material. The earmuff airbag comprises at least one hollow enclosed airbag. The earmuff sponge is wrapped on an outer surface of the earmuff airbag. The earmuff leather is wrapped on an outer surface of the earmuff sponge. The earmuff according to the present disclosure increases the conducting media of noise by adding the earmuff airbag. The noise will be continuously reduced after passing through different media, thereby enhancing the passive noise reduction ability of the earmuff, and improving the user experience. Moreover, the earmuff airbag comprises at least one hollow enclosed airbag, which provides a support force to the earmuff and can replace conventional sponge support for the earmuff.
