In this research, we have used 102 strong motion recordings from 2012 Ahar-Varzaghan earthquakes (Mw=6.5 and Mw=6.3) to study the form of attenuation of shear wave Fourier amplitude spectra of those two events. The analysis is carried out in a broad-band frequency range from 0.1 to 20 Hz. A bilinear shape for geometrical spreading is assumed based on nonparametric regression of the data. The hi...
The presence of S waves singularity points in low-symmetry anisotropic models significantly affects the topology slowness surfaces vicinity these and, consequently, results complications geometrical spreading. Thus, we analyse effect a point simple elliptical orthorhombic model with decoupled P wave.
Cell adhesion, spreading and migration require the dynamic formation and dispersal of contacts with the extracellular matrix (ECM). In vivo, the number, availability and distribution of ECM binding sites dictate the shape of a cell and determine its mobility. To analyse the geometrical limits of ECM binding sites required for cell attachment and spreading, we used microcontact printing to produ...
Sound backscattered to a sonar from a seabed decreases in intensity with increasing range (R) due to geometrical spreading. As a far-range approximation, a geometrical spreading correction of +30 log R decibels may be applied. A correction based on an accurate estimation of the area of the seabed ensonified by the sonar pulse incorporates additional terms that are a function of: range, sonic ra...
