We have compared the dorsoventral development of hemichordates and chordates to deduce the organization of their common ancestor, and hence to identify the evolutionary modifications of the chordate body axis after the lineages split.In the hemichordate embryo, genes encoding bone morphogenetic proteins (Bmp) 2/4 and 5/8, as well as several genes f
This study provides a novel methodology for the natural frequency estimation of the jet engine turbine blade by using the dimension check.This paper presents a summarization of the ongoing research devoted to the method for the turbine blade natural frequency estimation.The main target of the research presented in the paper is to develop a novel me
Abstract Accurate positioning and navigation play a vital role in vehicle-related applications, such as autonomous driving and precision agriculture.With the rapid development of Global Navigation Satellite Systems (GNSS), Precise Point Positioning (PPP) technique, as a global positioning solution, has been widely applied due to its convenient oper
