the conductivity distribution across the trans-european suture zone (tesz) is presented based on the measurements along a 400 km northeastern directed profile, starting from the german-polish basin, crossing the tesz and ending at the east european craton. two-dimensional inversion was applied to magnetotelluric transfer functions and magnetovariational responses corresponding to 38 long-period...

inverse modeling is one of the most elegant geophysical tools for obtaining 2-d and 3-d images of geological structure. determination of the geometry of bedrock, by nonlinear inverse modeling of gravity data, is the aim of this paper. the algorithm uses a nonlinear iterative procedure for simulation of bedrock geometry. at the first step, the nonlinear problem changes to a linear problem by a p...

One can access the space-time development of a heavy-ion reaction directly by imaging the source function from two particle correlation functions. In the case of like-charged pions, this imaging can be recast as a Fourier inversion problem. We will demonstrate how this inversion can be performed on full three-dimensional (i.e. in long, side and out coordinates) experimentally determined correla...

We present an application of the two-and-half dimensional (2.5D) multiplicative-regularized Gauss-Newton inversion method for the interpretation of the directional resistivity measurements [electromagnetic logging-while-drilling (LWD) measurements]. In this work, an inversion algorithm is employed for obtaining a two-dimensional (2D) resistivity distribution (pixel-based) of the subsurface. Sev...

two dimensional single frequency scalar vlf data modeling has been studied in this research. vlf method is one of the electromagnetic investigation methods. radio frequency waves are used for investigation of conductive deposits (paal, 1968). synthetic modeling and inversion of single frequency and multiple frequencies of vlf signals was done by oskooi (2004) for two dimensional simple structur...

Dirac semimetals associated with bulk fermions are well-known in topological electronic systems. In sharp contrast, three-dimensional (3D) phonons crystalline solids still unavailable. Here we perform symmetry arguments and first-principles calculations to systematically investigate 3D all space groups inversion symmetry. The results show that there two categories of depending on their protecti...
