A sequential multi-signature enabled multiple users to jointly sign a document in order.Xu,et al proposed a provably-secure certificateless sequential multi-signature scheme with constant signature length and pairing computations.However,it was shown that the scheme read more had a drawback in the verifying algorithm,and then it overcame the drawba
A 3D printing photosensitive resin structure has many advantages, such as good corrosion resistance, flexibility, low yield, and superior deformability; thus, it has been widely used in several fields.In this study, a new photosensitive resin structure was designed and built using 3D printing method.The new photosensitive resin structure is mainly
Introduction: The paper analyzes an experimental load-bearing structure of hybrid cast-in-place and precast lowrise residential buildings using wall panels with polymer tube confined concrete elements.Due to the improvement of design and process solutions, it is possible to decrease the cost, reduce the material and resource intensity of individual
This paper assesses the interface stability of the perovskite CsPbBr3 and transport layer CuI using density functional theory and band offset calculations.As a low-cost, more stable alternative to current hole transport materials, CuI may be used to template the epitaxial growth of perovskites such as CsPbBr3 owing to a 1% lattice constant mismatch
