This paper proposes a broadband metamaterial aperture antenna (BMAA) with a large capacity, low correlation coefficients and high radiation efficiency nautilus xpload lat pulldown for coincidence imaging in the terahertz band.The BMAA consists of a random modulated metamaterial aperture and a stripline structure as the feed system.Firstly, a metama

In the Early Cretaceous Jehol Biota, the toothless pterosaurs flourished with the chaoyangopterids and tapejarids playing a key role in understanding the early diversity and evolution of the Azhdarchoidea.Unlike the more diverse tapejarids, the rarer chaoyangopterids are characterized by a long and low rostrum, supporting a close relationship with

The paper starts from consideration of the theoretical basis of leadership, as well as its relationship with management as a basic approach in managing the organization, in order to arrive at a certain definition of military leadership.Leadership exists as long as man himself, throughout history it has been instinctively understood and experienced

Stripe rust (yellow rust), caused by Puccinia striiformis aireloom timeless odyssey f.sp.tritici (Pst), is one of the most devastating diseases of wheat throughout the world.H9020-1-6-8-3 is a translocation line originally developed from interspecific hybridization between wheat line 7182 and Psathyrostachys huashanica Keng and is resistant to most

The model-based flight control system design for a highly flexible flutter demonstrator, developed in the European FLEXOP project, is presented.The flight control system includes a baseline controller to operate the aircraft fully autonomously and a flutter suppression controller to stabilize the unstable aeroelastic modes and extend the aircraft&r
