Abstract: A connection management device may be used to with a common API to allow a host device of a client to securely connect to a remote provider network. The host device may only be able to use a connection management device by using a defined set of commands of a common API. A hardware root of trust may be pre-provisioned with security data (e.g., client certificate, encryption keys). A connection command may be used that is not specific to any particular communication protocol (e.g., WiFi, cellular, wired protocol). In response to receiving the connection command from a host device, the connection management device may perform commands specific to the communication protocol of the connection management device to connect to a remote provider network, use the security data for authentication, and establish a connection in accordance with the communication protocol based on the authentication.

Abstract: A two-step diffusion method for preparing high-performance dual-main-phase sintered mischmetal-iron-boron magnet belongs to the preparing technical field of rare earth permanent magnet materials. The compositions of the two main phase alloys are RE-Fe—B (RE is Nd or Pr) and (Nd, MM)-Fe—B (MM is mischmetal), respectively. First, PrHoFe strip-casting alloy is used as a diffusion source. Next, a PrHo-rich layer is uniformly coated on the surface of (Nd, MM)-Fe—B hydrogen decrepitation powders. The higher anisotropic fields of Pr2Fe14B and Ho2Fe14B are used to improve the coercivity. Then, the ZrCu strip-casting alloy is used as a diffusion source. A Zr-rich layer is uniformly coated on the surface of the powders after the first-step diffusion, which prevents the growth of the MM-rich main phase grains during the sintering process and the inter-diffusion between the two main phases, thus obtaining high coercivity.

Abstract: Techniques for storage management involve: receiving, at a storage server, an access request for target data from a client, wherein the access request occurs in a session between the storage server and the client; determining, based on attribute information of the client, security information of the session, wherein the security information indicates whether the session is subjected to antivirus protection; and executing, based on the security information, an access operation specified by the access request on the target data. Therefore, the performance of the storage server can be improved while the security of the storage server is ensured.

Abstract: A method for identifying a medium structure coupling and a fracture network morphology of a shale gas reservoir includes the following steps. Firstly, performing a fracturing test on shale cores by using a modified Brazilian disc test and categorizing the fracture network morphology. Secondly, performing a shale matrix-fracture structure and stress sensitivity test on the shale cores having different fracture network morphology. After that, determining a stress sensitivity constant of different fracture network morphology according to indoor core data and finally preparing an identification chart of the fracture network morphology based on an indoor core stress sensitivity test combined with a production practice. The identification chart can be applied to an actual fracturing well, and the fracture network morphology is directly identified by a real-time effective stress and a normalized flow.
