This paper introduces a variant for the symmetric matrix-based key distribution in sensor network introduced by Du et al. Our slight modification shows that the usage of specific structures for the public matrix instead of fully random matrix with elements in Zq can reduce the computation overhead for generating the public key information and the key itself. An intensive analysis followed by mo...

The aqueous radical homopolymerization of vinylidene fluoride (VDF), as well its copolymerizations with hexafluoropropylene (HFP) or perfluoromethyl vinyl ether (PMVE), and terpolymerization HFP PMVE, initiated by trifluoromethyl radicals (•CF3), generated from the ammonium persulfate (APS) potassium sulfinate (CF3SO2K) redox system are presented. optimization experimental conditions in terms i...
