click here To solve the privacy-preserving problem during the roaming authentication of wireless mobile networks, a novel roaming authentication scheme with anonymity was presented.An efficient certificateless aggregate signature scheme was first constructed, by introducing the online/offline signature and combining the aggregate signature.Com-pare
A variable-order time-fractional Kelvin peridynamics model is proposed, where the variable order is utilized to reflect the changes of viscosity in viscoelastic materials to effectively capture the damage and deformation of rock steady creep.The corresponding constitutive model is established by coupling a spring and an Abel dashpot.Through the Cap
The bifid mandibular condyle has also been termed as Double Headed Condyle or Condylar Duplication.Bifid condyle was first reported by Hrdlicka in 1941.Since then, to the best of our knowledge, about 49 cases of bifid condyle have been click here reported in medical literature.We present here six cases of bifid mandibular condyle that we encountere
