One important finding is that if the turbulence level in the flowing fluid is sufficiently large, parametric resonances may be suppressed or obscured. Indeed, this may be the reason why first-mode resonances did not materialize in these experiments. This may also explain the paucity of practical ...
In materials like concrete, the net effect is negative and the resonant frequency decreases as a function of wave amplitude. Empirical evidence suggests that the nonlinear hysteretic behaviour proportional to α dominates;37 therefore when exciting damaged materials at increasing strain amplitude level, ...
one can introduce Langevin noise terms in Eqs. (1) and (2), as is done in11,17. Doing so reveals that the amplitude-phase coupling has a frequency dependence identical to that of the intensity modulation responseH(f), a second-order low pass filter response with a resonance...
The coherent interaction between a two-level system and electromagnetic fields serves as a foundation for fundamental quantum physics and modern photonic quantum technology. A profound example is resonance fluorescence, where the non-classical photon emission appears in the form of a Mollow-triplet when...

A useful expression for the variance of Δ<sub>3</sub>(L) that accounts for finite sample size is discussed. An analysis of neutron resonance data presents the results consistent with a maximum likelihood method applied to the level spacing distribution. 展开 ...
Particular attention is given to the role played by the total resonance level width for it is well known that the R-matrix widths are energy dependent but the S-matrix widths are not. This different energy dependence leads to different analytic forms for the cross section and the n + 135Xe...

location with quality factors between 103and 104. Therefore, SPR based TFBG sensors open up a multitude of opportunities for single-point biochemical sensing in hard-to-reach spaces, and offer an extremely improved LOD level to molecular interactions together with very controllable cross-sensitivities...
