Abstract: A supersaturated solid solution soft magnetic material and a preparation method thereof are provided, belonging to the field of metal soft magnetic technologies. The supersaturated solid solution soft magnetic material is soft magnetic alloy with proportions of 72.0˜78.0 at % Fe, 12.0˜18.0 at % Si, 4.0˜12.0 at % Co and 1.0˜3.0 at % Ti.

Ti element is uniformly distributed in the ?-Fe (Si, Co) after supercooled solidification analyzed by X-ray energy spectrometer, a supersaturated solid solution alloy without Ti precipitation is obtained, and the soft magnetic alloy has low coercivity and high permeability.

Abstract: A system includes a database client, and a distributed database comprising database nodes. The distributed database may receive a database query from the client, determine that the query comprises a range of hash values of a table partition stored by a node of the distributed database, and determine that the range of hash values is not stored by other nodes of the distributed database. Responsive to determining that the range of hash values of the query is stored by the node and not by the other nodes, the database may generate an optimized distributed execution plan that includes the node that stores the range of hash values and excludes the nodes that do not include the range of hash values.

Abstract: The techniques described herein enable a private connectivity solution between a virtual network of a service consumer and a virtual network of a service provider in a cloud-based platform. The techniques map a service (e.g., one or more workloads or containers) executing in the virtual network of the service provider into the virtual network of the service consumer. The mapping uses network address translation (NAT) that is performed by the cloud-based infrastructure. As a result of the techniques described herein, a public Internet Protocol (IP) address does not need to be used to establish a connection thereby alleviating privacy and/or security concerns for the virtual networks of the service provider and/or the service consumer that are hosted by the cloud-based platform.
