P-wave dispersion was compared between two groups. student^,s T-test and pearson^,s correlation were used as needed.ResultsThere was a significant difference between the P-wave dispersion of the 2 groups (P=0.019). Maximum P-wave duration and P-wave dispersion in patients had strong ...

Tibetan and Indian lithospheres in the upper mantle beneath Tibet: evidence from broadband surface-wave dispersion. Geochem. Geophys. Geosyst. 14, 4260-4281.Agius, M. R., S. Lebedev. Tibetan and Indian lithospheres in the upper mantle beneath Tibet: Evidence from broadband surface-wave ...
This strategy avoids the experimental complication of physically generating the desired wavefronts at distinct wavelengths. We have recently used this approach for computational confocal imaging through MMF without physical wavefront shaping35. The focus quality achieved with this approach depends solely on...

We carefully selected 23 seismic stations that recorded the Rayleigh waves and divided them into 13 groups according to the azimuth angle between the earthquake and the stations; these groups mostly sample the Cordillera. In each group, we measured Rayleigh wave group velocity dispersion, which we ...
To measure this wavelength-dependent propagation delay, the optical source is modulated by a sinusoid wave and the propagation delay can be evaluated by the relative phase retardation of the received RF signal. By varying the wavelength of the tunable laser, the RF phase delay as a function of...
