Nowadays, given different definitions and conceptions on development, territorial planning lends to for various economic, social and geographical aspects, however its defensive and security perspectives have been taken into account to less extent. The present research is aimed to specify passive defense legal requirements in Territorial planning through outlining the most important rules on pas...

Type IV pili (T4P) are dynamic surface structures that undergo cycles of extension and retraction. T4P dynamics center on the PilB and PilT proteins, which are members of the secretion ATPase superfamily of proteins. Here, we show that PilB and PilT of the T4P system in Myxococcus xanthus have ATPase activity in vitro. Using a structure-guided approach, we systematically mutagenized PilB and Pi...

This paper mainly focuses on the mobile biped robots. It introduces the passive dynamic walking model, the landmark passive dynamic walking robot without knees, review of the development of passive walking robots. and the XZ-01 designed by CUPT, which has broken the Guinness World Records.

Magnetic-free optical isolators are critical components for the realization of integrated systems. The underlying physics passive nonlinear is not solely about breaking Lorentz reciprocity without requiring any external bias. Indeed, one major obstacle to operation Kerr-type was found be so-called dynamic reciprocity, which serious outcome that a backward signal cannot isolated in presence forw...
