Abstract Increasing data rates in wireless communications are accompanied with the need for new unoccupied and unregulated bandwidth electromagnetic spectrum. Higher carrier frequencies lower THz frequency range might offer solution future indoor communication systems of 100 Gbit/s beyond that cannot be located elsewhere. In this review, we discuss propagation channel measurements an extremely ...

Comparative Computational Analysis of NATO 5.56 mm, APM2 7.62 mm and AK-47 7.82 Bullet Moving at Mach 2.0 in Close Vicinity to the Wall Various rifles require unique bullets. Each bullet has its capability, speed, impact on target. In metropolitan warfare, several bullets are shot close solid walls. These near walls affect pressure distribution over entire asymmetric bullet. The influence a ref...

BackgroundOral anticoagulation (OAC) has been underused in patients with atrial fibrillation (AF) at risk for stroke. Data from registries shown OAC rates eligible of 50-60%. The use direct oral anticoagulants (DOACs) improved but contemporary data are lacking.ObjectiveThis study sought to evaluate real-world current practice a large health care system.MethodsOutpatient electronic records 341,7...

A parametrization of the Hamiltonian of the generalized Witten model of the SUSY QM by a single arbitrary function in d = 1 has been obtained for an arbitrary number of the supersymmetries N . Possible applications of this formalism have been discussed. It has been shown that the N = 1 and 2 conformal SUSY QM is generalized for any N . Submitted to the Physics Letters B.
