Authentication in a vehicular ad-hoc network (VANET) requires not only secure and efficient authentication with privacy preservation but applicable flexibility to handle complicated transportation circumstances as well. In this paper, we proposed Two-Factor LIghtweight Privacy-preserving scheme (2FLIP) enhance the security of VANET communication. 2FLIP employs decentralized certificate authority (CA) biological-password-based two-factor (2FA) achieve goals. Based on CA, several extremely...

We propose a new optical bistable device (OBD), which is constructed by connecting two symmetrical fiber Bragg gratings with ytterbium-doped to form nonlinear Fabry–Perot cavity. The principle of this OBD described using the transfer-matrix method, and groups transmitted reflected bistability loops under different parameters are investigated symmetrically. Compared single grating switching, whose switching power greater than 2 kW, has evident merits in reducing less 45 mW.

Abstract Objectives Carbon dots (CDs), as a fascinating class of fluorescent carbon nanomaterials, have been proven to be powerful tools in the field bioimaging and biosensing due their small size, suitable photostability favourable biocompatibility. However, cellular uptake free CDs lacks selectivity same negative charges cell membranes may cause inefficient internalization. In this study, an efficient detecting targeting nanosystem was developed based on DNA aptamer AS1411 modified with...

Circularly polarized light carries spin angular momentum, which may lead helicity-resolved Raman scattering to be sensitive the electronic configuration in magnetic materials. Here, we demonstrate that all modes 2D ferromagnet VI3 show different intensities left and right circularly at low temperatures, gives direct evidence of time-reversal symmetry breaking. By measuring circular polarization dominant mode with respect temperature field, ferromagnetic (FM) phase transition hysteresis...

Graphene nanocomposites can significantly enhance the thermal conductivity and mechanical properties of ceramics at relatively low nano-filler addition. Herein, graphene nano-platelet reinforced Si3N4 (GNP/Si3N4) composites were prepared by hot press (HP) sintering using fluoride (AlF3, MgF2) sintering-additives. The microstructural revealed enhanced crystallization degree density GNP/Si3N4 with different concentrations nano-platelets (GNPs). These help to achieve a improved (from 82.42...
