The magnetorotational instability(MRI) in the Kerr spacetime is studied on a 3+1 viewpoint. The Maxwell's equations are expressed in a circularly orbiting observer's frame that co-rotates with matter in Keplerian orbits. The hydromag-netic equations are represented in a locally nonrotating frame(LNRF). There exist large proper growth rates in MRI around a rapidly rotating black hole. The large ...

ABSTRACT The present work proposes a new formalism for the inner regions of neutrino-dominated accretion flows (NDAFs) by considering self-gravity, where neutrino opacity is high enough to make neutrinos trapped becoming dominant factor in transportation energy and angular momentum over magneto rotational instability. We investigate possibility gravitational instability fragmentation model high...

Macromotion of the femoral component was analyzed in seven loose hips associated with six patients utilizing the manual compression and distraction test. The mean vertical and varus movement of these hips were 6.4 mm and 1.2 degrees, respectively. Out of a total 120 cementless total hip arthroplasties, there was no macromotion in the control group of six patients with moderate to severe thigh p...

We show that holographic models of QCD predict the presence of a Chern-Simons coupling between vector and axial-vector mesons at finite baryon density. In the Anti de Sitter/Conformal Field Theory dictionary, the coefficient of this coupling is proportional to the baryon number density and is fixed uniquely in the five-dimensional holographic dual by anomalies in the flavor currents. For the li...

We analyse the characteristics of two-fluid mixing in T-shaped microchannels on rotating platforms (Lab-on-a-Compact-Disk framework). Three regimes of mixing were identified based on the distinct flow behaviour in each of these regimes. A diffusion-based mixing regime was obtained for low rotation speeds. A Coriolis force based mixing regime was observed for intermediate rotation speeds, which ...
