A method is described for multislice EPISTAR that perfectly compensates magnetization transfer effects. Inflowing arterial spins are labeled with a 360 degrees adiabatic pulse. Two control tags are applied sequentially at the same location as the labeling pulse, each with a 180 degrees adiabatic pulse so the total RF irradiation, frequency shift, and bandwidth of the labeling and control pulses...

may be described using complex shock wave analysis [ I . Fig. 1. Energy contained in rise time portion of pulse is used to reverse Recently, an appro.ximate but useful model describing this spins in ferrite transmission line. Magnetic field profile (dashed curve) phenomena was reported 121. Although some experimental in spin reversal region, as it emerges from output of line, represents • resid...

  intravenous glucocorucoid pulse therapy is a common treatment for immunologically origin diseases but it can not be considered a completely bening treatment.the effects of long term administration of glucocorticoids on calcium and phosphorus metabolism are week known ,but is less in known about the effect of pluse therapy.the purpose of this study was to investigate the effect of methylpredn...

We study pulse propagation in Er-doped fiber amplifiers (EDFA) within the framework of a spectrally resolved pulse rate-propagation equations model. Our model accounts for the effects of gain dispersion, gain saturation, waveguide and chromatic dispersion, and amplified spontaneous emission. This model allows us to approximate the effects of nonlinear resonant dispersion on short pulse amplific...

INTRODUcnON ing was halted in 1962. Subsequently, 11.01 Explosions of conventional reliance has been placed on underhigh explosives can produce electroground testing, analysis of existing atmagnetic signals and so the generation mospheric test data, nonnuclear simulaof an electromagnetic pulse (EMP) from tion, and theoretical calculations. a nuclear detonation was expected. Extended efforts hav...
