Abstract: An electronic device (such as an access point) may receive a packet (or a frame) from a second electronic device, where the packet includes an encrypted unique identifier of the second electronic device. For example, the encrypted unique identifier may be included in a manufacturer-specific information element in a management packet. Then, the electronic device may decrypt the encrypted unique identifier using an encryption key or a secure hash function to obtain the unique identifier. Next, the electronic device may determine whether the second electronic device is an instance of an authorized access point in the WLAN based at least in part on the unique identifier. Note that the second electronic device may be an instance of an authorized access point when the unique identifier is associated with a manufacturer of the electronic device and/or the second electronic device.

Abstract: Provided are malR-knockout Bacillus licheniformis strain, a construction method and a use. Using a genetic engineering method, gene, namely, the malR gene, which is in charge of conducting the transcription of the carbon metabolism transcription factor MalR, in the genome of Bacillus licheniformis DW2 is knocked out, thereby successfully obtaining Bacillus licheniformis DW2?malR, from which the malR gene has been deleted. In comparison with Bacillus licheniformis DW2, the strain obtained by the construction can improve the Bacitracin yield in a fermentation broth during Bacitracin fermentation by at least 23%.

Abstract: Provided herein are systems and methods for an efficient method of replicating share objects to remote deployments. For example, the method may comprise modifying a share object of a first account of a data exchange into a global object wherein the share object includes grant metadata indicating share grants to a set of objects of a database. The method may further comprise creating, in a second account of the data exchange, a local replica of the share object on the remote deployment based on the global object, wherein the second account is located in a remote deployment. The set of objects of the database may be replicated to a local database replica on the remote deployment and the share grants may be replicated to the local replica of the share object.

Abstract: An observation system and determination method for the re-suspension quantity of submarine sediments by deep-sea internal waves. The observation system comprises a submarine observation platform, a mooring rope, and an anchor mooring counterweight. Acoustic release transponder, a single-point current meter, a turbidity meter, a high-precision temperature and salinity detector, and a sediment catcher are mounted on the submarine observation platform.

Abstract: The present invention provides a three-port converter with magnetic integration and current ripple cancellation. With magnetic integration technology, the number of magnetic rings is reduced, and the number of driving coupling transformers is also reduced, thereby greatly reducing the size and weight of the whole converter; and with a current ripple cancellation branch, the amount of current ripples flowing through the three ports is very low and close to zero. The three-port converter of the present invention reduces the influence of electromagnetic interference and simultaneously saves the filter cost so that the busbar current and battery current are smoother.

Abstract: An iterative framework to optimally integrate various distributed generations (DG) and demand responsive resources (DRR) within a distribution system into transmission market clearing. The concept of distribution aggregated demand and distribution aggregated utility represent a summed distribution level information in consuming electricity that encompasses preferences of the individual DGs and DRRs. This distribution level preference, which is derived based on unbalanced three-phase AC optimal power flow, is bid into the transmission level for optimal market clearing. When the aggregated preferences cannot be obtained, an iterative method enables the transmission and distribution networks to exchange price and demand information. A competitive equilibrium is reached when the method converges to a price-demand coupling point.
