With W = 0.7 μm, a single micro-domain can be probed, and hence, the SHG intensity is determined by the coherent contribution from the constituent nano-sized domains.
As we have already seen in a previous study [1], this happens in poly 3-hexylthiophene) (poly 3-hexylthiophenel C61 butyric acid methyl ester (P3HT) solid blends, in which the coherent contribution andsing from the PCBM crystalline phase seems to affect the interpretation of the polymer dynamics.
Therefore, unlike the energy spectrum, the bimagnitude, i.e., magnitude bispectrum estimate, contains the peaks in the bifrequency domain caused only by coherent contributions in the signal under study.
If the cross-polarized case is now considered, the received power is basically due only to diffuse scattering (because of the non-zero k xpol value), since the coherent contributions carry a negligible power because of the polarization mismatch.
Modeling the spatial correlation of ground motion residuals, caused by coherent contributions from source, path, and site, can provide valuable loss and hazard information, as well as a more realistic depiction of ground motion intensities.
Extraction of these fluctuation rates can, however, be hampered by the presence of coherent contributions, originating from elastic scattering, and/or inelastic scattering modes which overlap in the space/time domain with the incoherent single-particle motions.
In Eq. (1), β∈ℕ is the shape parameter of the Nakagami distribution representing the amount of fading factor, with (phantom {dot {i}!}Omega ^=Omega +rho 2b_{0}) representing the average power from the coherent contributions, whereas K ν is the modified Bessel function of the second kind and order ν.
SHG studies on BiFeO3 have been performed by several research groups who could provide detailed symmetry information of tetragonal-like and rhombohedral-like phases, but it should be noted that most of the works have been done with assumptions of the homogeneous and coherent contributions of constituent domains [18, 19].
Thus, we can see that the large positive score of a conserved residue (histidine) is made by coherent contributions from multiple singular components whereas the scores of residues that are not conserved may be positive but small due to incoherent contributions.
Interestingly, the obtained plateau values are similar to the values obtained at fast MAS, implying that coherent contributions to R1ρ are indeed efficiently suppressed, even at the lower MAS frequency.
2) The remaining coherent contributions to the effective R2 rates in a CPMG experiment are almost, but not entirely independent of the CPMG frequency.[ 11] Thus, observed variations of the effective R2 in the CPMG experiment may to some extent be artifactual.
