Abstract: A data management system (DMS) may facilitate an investigation procedure for a set of one or more virtual machines (VMs) hosted in a first environment. The DMS may receive an indication of a selection of one or more sets of VMs and corresponding snapshots for the investigation procedure. The corresponding snapshots may be stored in a second environment, and each snapshot may be associated with a version of a respective set of VMs. The DMS may mount the one or more sets of VMs to one or more testing environments different than the first and second environments. The mounting may use the snapshots stored in the second environment to provide the testing environments with query access to respective versions of the sets of VMs hosted in the first environment. The DMS may perform query operations between the first environment and the testing environments as part of the investigation procedure.

Abstract: The composition includes a vinyl-substituted polysiloxane having at least two vinyl groups, a hydrosilylation catalyst, a hydrosilyl-substituted polysiloxane having at least two silicon-hydride groups, and a phosphorous-containing flame retardant encapsulated in a crosslinked, nitrogen-containing polymer. The composition may be a two-part composition including a first part and a second part. The first part includes a vinyl-substituted polysiloxane, a hydrosilylation catalyst, and a phosphorous-containing flame retardant encapsulated in a crosslinked, nitrogen-containing polymer. The second part includes a second vinyl-substituted polysiloxane and a hydrosilyl-substituted polysiloxane. A battery module including a plurality of battery cells and the composition at least partially encasing the plurality of battery cells is also disclosed.

Abstract: A base station antenna and a base station including the base station antenna are provided. A base station antenna includes a transceiver array configured to output M signals, wherein M is an integer greater than 1; an antenna array including N antenna units, wherein N is an integer greater than M; a first-level signal allocating network configured to allocate first power to the M signals, and output P signals, wherein P is an integer greater than M; a signal synthesizing network including multiple signal synthesizers, wherein each of the multiple signal synthesizers utilizes two signals of the P signals to synthesize two output signals; and a second-level signal allocating network configured to allocate second power to signals output by the multiple signal synthesizers, and output N signals to the N antenna units.
