Group I chitin deacetylases (CDAs), CDA1 and CDA2, play an essential role in cuticle formation and molting in the process of insect wing development.A recent report showed that trachea are able to take up a secreted CDA1 (serpentine, serp) produced in the fat body to support normal tracheal development Vaporizer in the fruit fly Drosophila melanoga
The research of LEFP (linear explosive forming projectile) is of great value to the development of new warhead due to its excellent performance.To further improve the damage ability of the shaped charge warhead, a special shell overhanging structure was designed to increase the charge based on the traditional spherical charge, in which case the cru
In direction finding, the use of noncircularity Toner of signals arriving at a sensor array can allow us to improve estimation performance.It will be more realistic, rather than the assumption of all noncircular sources, to consider some sources transmitting circular signals.In the presence of both circular and noncircular signals, this paper prese
