Abstract: Lease transfer between master and slave replicas is described. A master replicator determines that an initial master replica lease takes effect. On determining that a master replica transfer needs to be performed, sending a transfer preparation message to a target replicator prior to expiration of a current master replica lease. The target replicator locally starts and calculates a new master replica lease and returns a readiness response to the master replicator. The master replicator sends a lease extension message to remaining slave replicators to extend local corresponding leases. After receiving lease extension success responses of a majority of the slave replicators, the master replicator terminates the local master replica lease of the master replicator in advance, and sends a transfer confirmation message to the target replicator. The target replicator validates the new master replica lease to make the target replicator a new master replicator.

Abstract: An analysis method and an electronic apparatus for breast image are provided. The method includes the following steps. One or more breast ultrasound images are obtained. The breast ultrasound images are used for forming a three-dimensional (3D) breast model. A volume of interest (VOI) in the breast ultrasound image is obtained by applying a detection model on the 3D breast model. The VOI is compared with a tissue segmentation result. The VOI is determined as a false positive according to a compared result between the VOI and the tissue segmentation result. The compared result includes that the VOI is located at a glandular tissue based on the tissue segmentation result. In response to the VOI being located in the glandular tissue of the tissue segmentation result, the VOI is compared with the lactiferous duct in the 3D breast model.

Abstract: A single-source microwave heating device has a first power-divider, a microwave emitting module and a shifting wave channel. An input port and an isolated port are located on one side of the first power-divider. Two output ports are located on an opposite side of the first power-divider.

A phase-shift provided by the first phase-shifting module varies according to a position of the first phase-adjusting assembly such that positions of standing-wave crests in the standing-wave heating chamber can be moved back and forth to achieve uniform heating.

Abstract: Embodiments disclosed herein provide compositions, methods, and uses for respiratory syncytial viruses (RSV) and immunogenic compositions thereof. Certain embodiments provide RSV having a mutated NS1 protein, where the mutation causes the uncoupling of the NS1 protein's replication and type I interferon (IFN) antagonist functions. In some embodiments, this uncoupling can produce virions capable of inducing a strong, long-lasting innate immune response while maintaining its ability to replicate in vitro. Also provided are methods for amplifying RSV in host cells, wherein amplified RSV has mutated NS1 protein in which the protein's replication and IFN antagonistic functions are uncoupled. In certain embodiments, the amplified RSV having mutated NS1 protein is formulated into immunogenic compositions, including vaccines. Other embodiments provide methods for inducing an effective immune response against RSV infection in a subject.
