In this paper, the nonlinear rate equations governing a quantum dot laser isused to simulate the transient as well as the steady-state behaviors of the laser.Computation results show that the rate equations are capable of simulating true behaviorof a quantum dot laser. Then, the pump rates of the rate equations (which show indirectelectrical pumping of the quantum dots through a wetting layer) ...

The periodic and random variations in human heart rate are physiologically and clinically significant. A wide variety of signal processing techniques have been applied to heart rate time series to extract information regarding heart rate variability. The heart rate response to a startling auditory stimulus is a useful measure of an individual's cardiovascular reactivity and may be related to th...
