Three Dimensional Magnetohydrodynamical Simulations of Core Collapse Supernova

We show three-dimensional magnetohydrodynamical simulations of core collapse supernova in which the progenitor has magnetic fields inclined to the rotation axis. The simulations employed a simple empirical equation of state in which the pressure of degenerate gas is approximated by piecewise polytropes for simplicity. Neither energy loss due to neutrino is taken into account for simplicity. The...

Variability of Unstably Accreting Neutron Stars: Three-Dimensional Magnetohydrodynamic Simulations

We investigate the photometric variability of neutron stars accreting through a magnetic Rayleigh-Taylor-type instability at the disk-magnetosphere interface, and compare it with the variability during stable accretion, with the goal of looking for possible quasi-periodic oscillations. The lightcurves during unstable accretion are generally chaotic. They often show signs of quasi-periodic varia...

ISSCC 2005 / SESSION 11 / ULTRA WIDEBAND SOLUTIONS / 11 . 9 11 . 9 A 0 . 13 μ m CMOS UWB Transceiver

In addition to broadband gain and input matching requirements, the UWB standard also poses a tight specification on the band switching time (9ns), thus precluding the direct synthesis of frequencies by phase locking. An approach suggested for this task incorporates a single phase-locked loop (PLL) and a number of single-sideband (SSB) mixers to generate different frequencies that are present at...

40 A global coupled climate model representative of the current generation of models is 41 shown to simulate most first order aspects of El Niño events, their teleconnections over 42 North America, and the associated observed patterns of extremes in present-day climate. 43 Future El Niño teleconnection patterns over the U.S. are projected to shift eastward and 44 northward due in part to the di...
