In the final runs, the following parameters were refined: scale factor; background coefficients; zero-point error; pseudo-Voigt corrected for asymmetry parameters; occupancy of Bi, Te, and Se; positional coordinates; and anisotropic displacements for all the atoms.
The following parameters were refined in the final runs: scale factor, background coefficients, zero-point error, pseudo-Voigt corrected for asymmetry parameters, occupancy of Bi and Te, positional coordinates and anisotropic displacements.
An exact treatment based on the inherent background coefficients that describe the background amplitudes in the scattered field is employed to investigate the scattering of time-harmonic plane acoustic waves by an arbitrarily thick hollow isotropic functionally graded cylinder submerged in and filled with non-viscous compressible fluids.
In this approach, a reference measurement is not needed and the background optical properties do not need to be known but a model for the uncertainty of the background coefficients is needed.
Denote background diffusion coefficient and absorption coefficient by D 0 and μ a, the optical property distributions can be written as D (r ) = D 0 + δ D (r ) and μ a (r ) = μ a + δ μ a (r ).
The effect of PM exposure on mortality rate (m) ratio is typically predicted based on the following regression formula: ln(m ) = α + β × E + ε where α is the background mortality coefficient, β is the exposure-response coefficient and E is exposure (ε is a nuisance parameter).
It is demonstrated how this effect can be included via a non-dimensional dynamic background flexibility coefficient, extracted from a classic modal analysis for the particular frequency of the selected mode.
It has the background transport coefficient μ = 0.1 mm−1 and the albedo λ = 0.999.
The background absorption coefficient is taken as μ a = 0.1 cm−1, with two regions of 10% perturbation.
