Vibrio parahaemolyticus,a gram-negative halophilic bacterium that naturally inhabits coastal waters,causes gastroenteritis,skin infections,and septicemia in human beings[1].This bacterium produces multiple virulence factors,including thermostable direct hemolysin(TDH),TDH-related hemolysin(TRH),type Ⅲ secretion system 1(T3SS1),T3SS2,type Ⅵ secretion system 1(T6SS1),and T6SS2[1].Furthermore,Ⅴ.parahaemolyticus forms biofilms on the surface,which help it in adapting to unfavorable conditions[2].Mature biofilm formation requires special structures,including lateral and polar flagella,exopolysaccharide(EPS),and type Ⅳ pili[2].

Attribute-based encryption(ABE) has been a preferred encryption technology to solve the problems of data protection and access control, especially when the cloud storage is provided by third-party service *** can put data access under control at each data item level. However, ABE schemes have practical limitations on dynamic attribute revocation. We propose a generic attribute revocation system for ABE with user privacy protection. The attribute revocation ABE(AR-ABE) system can work with any type of ABE scheme to dynamically revoke any number of attributes.

Semimetallic bismuth（Bi） is one of the most effective strategies for reducing the contact resistance of two-dimensional transition metal dichalcogenide field effect transistors（FETs）. However, the low melting point of Bi contact（271.5℃） limits its reliable applications. In this study, we demonstrated that the temperature stability of Bi-contacted electrodes could be improved by inserting a high-melting point semimetallic antimony（Sb） between the Bi contacting layer and the gold（Au） capping layer. The proposed Bi/Sb/Au contact electrodes tended to form a metal mixture with a continuous surface during the heating process（Voids appeared on the surface of the Bi/Au contact electrodes after heating at 120℃）. Because of the improved contacting layer formed by the semimetal Bi/Sb alloy, the fabricated Bi/Sb/Au-contacted molybdenum sulfide（MoS2） FETs with different gate lengths demonstrated higher on-state current stability after heating treatment than the Bi/Au contact. Because of the Bi/Sb/Au contact and poly（methyl methacrylate） package, the MoS2FETs demonstrated time stability of at least two months from the almost unchanged transfer characteristics. The electrical stability indicates that the insertion of semimetallic Sb is a promising technology for reliable Bi-based contact.
