Under the weak-probe approximation, we theoretically investigate the transient gain-absorption property of the probe field in a four-level asymmetric semiconductor quantum well system.
The dependence of transient gain-absorption property of the probe field on the intensity and the frequency detuning of the strong coupling field is also given.
We find that the strength of Fano interference and the energy splitting affect the transient gain-absorption property of the weak continuous-wave (CW) probe field or Gaussian-pulse probe field dramatically.
Sudden faults of small amplitude can also cause unacceptable results due to the transient amplification by controller gains, where linear working limits of system's components are exceeded.
Many people experience transient weight gain, putting on a few extra pounds during the holidays or gaining 10 or 20 pounds during the first years of college that they lose again.
There may be some transient political gain for the mayor in this latest attack on free expression in the artistic arena.
Model predictions of the transient mass gain per unit area of exposed surface QCM sensor, resolved at a single pulse sequence, were in good agreement with experimental data under a wide range of operating conditions.
We show, both theoretically and experimentally, that delayed repression induces transient increase and heterogeneity in gene expression before the gain of stability effected by the negative feedback.
We investigated statistical properties of these transient waves to gain a dynamical understanding of spontaneous episodes in migraine.
Many researchers attempted to use numerical simulation techniques to analyse the molten flow through the gating system, which has an advantage to accurately predict subtle transient events and gain more profound information about the behaviour of metal stream.
In contrast to males, this transient positive weight gain is accompanied by unaltered daily food intake, fecal output or rectal temperature, but a significant increase in oxygen consumption, notably in the light phase, with – as in male mice – no change in RER (Table 2).
