A unidirectional conditional proxy re-encryption scheme based on non-monotonic access structure Bin Wang Information Engineering College of Yangzhou University No.196 West HuaYang Road, Yangzhou City, Jiangsu Province, P.R.China E-mail: [email protected] Abstract: Recently, Fang et al. [6] introduced an interactive(bidirectional) conditional proxy re-encryption(C-PRE) scheme such that a proxy ca...

Leaf structure has been shown to be an important determinant of leaf photosynthetic characteristics, yet the nature of this relationship remains ambiguous. It has been suggested that intra-leaf shading of chloroplasts may explain the negative influence of increasing leaf thickness/density on mass-based photosynthesis. To explore further the importance of light-mediated functional limitations co...
