While cartilage is an ancient tissue found both in protostomes and deuterostomes, its mineralization evolved more recently, within the vertebrate lineage.SPARC, SPARC-L, and the SCPP members (Secretory Calcium-binding PhosphoProtein genes which evolved from SPARC-L) are major players of dentine and bone mineralization, but their involvement in the
Main rotor actuator Infusions failure leads to catastrophic accidents for single main rotor helicopters.This paper focuses on safe landing trajectories after an actuator is locked in place by the remaining actuators, without introducing other control inputs.A general swashplate geometry is described, and new reconfiguration solutions for the contro
Unmanned aerial vehicles (UAVs) serve as airborne access points or base stations, delivering network services to the Internet of Things devices (IoTDs) in areas with compromised or absent infrastructure.However, urban obstacles like trees and high buildings can obstruct the connection between UAVs and IoTDs, leading to degraded communication perfor
