We investigate the non-adiabatic dynamics of spinning black hole binaries by using an analytical Hamiltonian completed with a radiation-reaction force, containing spin couplings, which matches the known rates of energy and angular momentum losses on quasi-circular orbits. We consider both a straightforward post-Newtonian-expanded Hamiltonian (including spin-dependent terms), and a version of th...

The Iron Gates gorge system is formed by the convergence of Carpathians and Balkan mountain ranges that collide plunge directly into Danube River (Fig. 1). geographical conditions this region have created a frontier zone in different periods, historical context article deals specifically with period between 1429 c. 1435 when castle was placed under control contingent from Teutonic Order to help...
