In this article, we explore the performance of optical wireless technology for ensuring audio communications inside an aircraft cockpit.One advantage is that, unlike radio frequencies, opaque objects block optical signals and, therefore, signals cannot pass through walls.This can reduce security risks against eavesdropping and hacking of the physic
The shape of the brain influences skull morphology in birds, and both traits are driven by phylogenetic and functional constraints.Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D-preserved vertebrate brains are not known from the fossil record, so brain endocasts often serve as prox
Abstract Background The high-speed hand-piece bur is one of the methods to perform tooth sectioning during the minimally traumatic extraction of impacted mandibular third molars.During tooth sectioning, the breakage of the bur might take place when it is improperly used.Three cases of the breakage and displacement of a high-speed hand-piece bur dur
