Furthermore, doping-induced point defects, such as atomic mass fluctuation and lattice deformation, yield a reduction in the lattice thermal conductivity.
A pulsating harmonic oscillator of natural frequency ω0 and mass fluctuation γ(t)= 12M˙/M="ενcosνt is considered as a model for a parametrically excited system in dynamics, for a pumped electrical circuit or in quantum optics.
This technique is to be considered terminal and is therefore not intended for extended longitudinal studies of beta cell mass fluctuation.
It consists of a piezo stack that produces mass fluctuations, which in turn can lead to net time-averaged thrusts.
Also one should be careful with QWs in the band inversion point, as in that case additional scattering mechanism (scattering on effective mass fluctuations) could suppress the mobility and increase resistance and noises.
The mantle response to these large ice mass fluctuations and the change in mass between the oceans and land caused, and continues to cause, measureable crustal deformation at hundreds of kilometres from the ice margins.
An important difference in this study is that only the mechanical power developed by the piezo stack is considered to be responsible for the mass fluctuations, whereas prior works focused on the electrical energy into the system.
To obtain the optimal operation characteristics of a semimetal MCT QW channel for THz detectors, one should provide a high electron concentration in the QW, and adjust the channel chemical composition x to be close to the band structure inversion point (just below the inversion point, to avoid activating an additional mechanism of scattering on the effective mass fluctuations).
The number of parameters is equal to 5, they are (1) σ8, the dispersion of the mass fluctuations in the sphere with radius 8 h−1Mpc, (2) n, the slope of the density perturbation spectrum, (3) Ων, the density of hot dark matter, (4) Ωb, the density of baryons, and (5) h, the Hubble constant H0 = 100 hkms−1Mpc−1.
Monopoles radiate sound through volume or mass fluctuations, and have one-dimensional pressure fields.
It is suggested that number of specific genes can determine bone mass, its fluctuation, and severity of the resorption process.
