How has Lunar science developed? A bibliometric analysis and systematic review
Lunar exploration is a significant process to unravel the evolutionary history of the Earth-Moon system and the pivotal foundation for the exploration of the solar system.A total of 49,161 articles recorded in a comprehensive online literature database between 1959 and 2018 were reviewed to address the development of lunar science in six aspects: p
A randomized, non-inferiority study comparing efficacy and safety of a single dose of pegfilgrastim versus daily filgrastim in pediatric patients after autologous peripheral blood stem cell transplant.
PurposeTo assess the non-inferiority of pegfilgrastim versus filgrastim in speeding the recovery of polymorphonuclear cells (PMN) in pediatric patients who underwent autologous peripheral blood stem cell transplant (PBSCT).MethodsThe sample size of this randomized, multicenter, phase III study, was calculated assuming that a single dose of pegfilgr
Easy set-up and in situ automatic gear diagnostic system using only laser reflection
We developed a new method that can diagnose damage on a gear tooth surface using a laser beam without a rotary encoder.The method procedure is as follows: 1) The tooth bottom, the tooth tip and their two median values are detected using the NORMALISING SHAMPOO differential values of the laser reflection data.2) The gear rotation speed is calculated
