Abstract: The application discloses a method for preparing crude polysaccharides based on synergistic fermentation with corn stover and fungus, including the following steps: step (1): drying corn stover, pulverizing, placing in a hydrothermal reactor, adding deionized water, sealing the hydrothermal reactor, placing in a heating device, reacting, taking out reaction products, centrifuging and drying a solid; step (2): adding the products obtained in step (1) and dried bean curd residue to a container, adding distilled water, mixing uniformly, sterilizing to obtain a mixed material, inoculating a fungus inoculum under aseptic conditions, sealing the container and cultivating in the dark to obtain crude polysaccharides. The disclosure uses corn stover and bean curd residue as raw materials to achieve efficient utilization of discarded biomass, reduce environmental pollution, and improve utilization of corn stover.

Abstract: An electronic device (such as an access point) that selectively performs authentication to a network is described. During operation, the electronic device provides an identity request addressed to the second electronic device. Then, the electronic device receives, associated with the second electronic device, an identity response. In response, when the authentication computer is unavailable, the electronic device accesses, in memory, a predefined hash function and associated authentication parameters for an authentication technique. Next, the electronic device performs authentication with the second electronic device based at least in part on the predefined hash function, where the authentication is compatible with the authentication technique (a type of EAP). Moreover, the electronic device generates an encryption key, and establishes secure communication with the second electronic device by performing a four-way handshake with the second electronic device based at least in part on the encryption key.

Abstract: Dielectric super-junction transistors use combinations high dielectric relative permittivity materials and high-mobility materials. An associated electronic device includes a junction portion of a barrier layer adjacent a gate contact and a drain contact. A layered semiconductor device is configured with a junction dielectric permittivity that is greater than a channel dielectric permittivity in the channel layer. The junction portion has a dielectric structure that polarizes carriers within the junction portion such that excess charge on the gate is compensated by an opposite charge in the junction portion of the barrier layer proximate the gate. A sheet charge in the barrier layer is increased to form a depletion region with the channel layer that avoids a conductive parallel channel in the barrier layer to the drain contact.
