The Hartle-Hawking wave function is known to be the Fourier dual of Chern-Simons or Kodama state reduced mini-superspace, using an integration contour covering whole real line. But since a general solution Hamiltonian constraint (with given ordering), its should provide (i.e. beyond mini-superspace) Wheeler DeWitt equation representing in metric representation. We write down formal expression f...

Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (PSO) algorithm. The ...
