Earthquakes can be triggered by local changes in the stress field (static triggering) due to nearby earthquakes or by stresses caused by the passage of surface (Rayleigh and Love) waves from a remote, large earthquake (dynamic triggering). However, the mechanism, frequency, controlling factors and the global extent of dynamic triggering are yet to be fully understood. Because Rayleigh waves inv...

The scattering of flexural waves by a hole in a thin plate traversed by a beam is modeled here by coupling the Kirchhoff-Love and the Euler-Bernoulli theories. A closed form expression is obtained for the transfer matrix (T-matrix) relating the incident wave to the scattered cylindrical waves. For this purpose, a general method has been developed, based on an analogous impedance method for acou...

Cross sections and analyzing powers are calculated for the 40Ca( p, 2P)K reaction at proton incident energy of 300 MeV. The t-matrix elements are given by the effective nucleon-nucleon amplitudes of Love-Franey. The optical potentials for distorted waves are calculated by relativistic impulse approximation (RIA). Our calculations are somewhat in poor agreement with experimental data and finally...

Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...

temper of learning when men study words not matter; for words are but the images of matter, and, except they have life of reason and invention to fall in love with them, is all one as to fall in love with a picture." The great prophet of inductive philosophy has here touched the very core of the errors and vanities which gather round epidemiological research, and impede progress in the acquisit...
