Cells of higher eukaryotes process within minutes double strand breaks (DSBs) in their genome using a non-homologous end joining (NHEJ) apparatus that engages DNA-PKcs, Ku, DNA ligase IV, XRCC4 and other as of yet unidentified factors. Although chemical inhibition, or mutation, in any of these factors delays processing, cells ultimately remove the majority of DNA DSBs using an alternative pathw...

Abstract This paper introduces the research on guide band welding in China and other countries, analyzes characteristics of bands produced by remelt deposit application process to joining between thin-walled submunition-based projectiles with a large caliber launched howitzer. In addition, this raises performance testing requirements for grooveless process.

A structure for joining 6061T6 aluminum alloy tube and AZ31B magnesium shaft via the magnetic pulse crimping process was proposed. The forming process, mechanical properties, failure modes, corrosion behaviors of joint were studied. results showed that enormous Lorentz force drove wall to move towards groove at high velocity, thus realized locking formed joint. Through torsion tests, it found p...
