Magnetotelluric (MT) problems often contain different subdomains where the conductivity of the media depends upon one, two, or three spatial variables. Traditionally, when a MT problem incorporates a three-dimensional (3D) subdomain, the numerical method employed for simulation and inversion was 3D over then entire domain. In here, we propose to take advantage of the possibly lower dimensionali...

where the weights k and nodes k are complex numbers, which depend on n, but do not depend on the transform f̂ or the time argument t. Many different algorithms can be put into this framework, because it remains to specify the weights and nodes. We examine three one-dimensional inversion routines in this framework: the Gaver-Stehfest algorithm, a version of the Fourier-series method with Euler su...

The title coordination polymer, [Ag(2)(C(10)H(4)O(8))(C(12)H(9)N(3))(2)](n), was prepared by a hydro-thermal method. The Ag(I) atom exists in a strongly distorted trigonal coordination environment. Two Ag(I) ions related by an inversion centre are coordinated by two 2-(3-pyrid-yl)benzimidazole ligands, forming a centrosymmetric cyclic dimer. The bridging bidentate 2,5-dicarboxy-benzene-1,4-dica...

In the title compound, {[Fe(II)(C(8)H(4)N(2))(2)(H(2)O)(2)][Fe(III)Cl(4)](2)·4CH(3)NO(2)}(n), the Fe(II) and Fe(III) ions are hexa- and tetra-coordinated, respectively. Each unique benzene-1,4-dicarbonitrile mol-ecule lies across a crystallographic inversion centre and bridges two Fe(II) ions (each situated on an inversion centre), generating two-dimensional (4,4) square grid layers. The tetra-...

The titled problem of coupled thermoelasticity for porous structure has been solved with an instantaneous heat source acting on a plane area in an unbounded medium. The basic equations of thermoelasticity, after being converted into a one-dimensional form, have been written in the form of a vector-matrix differential equation and solved by the eigenvalue approach for the field variables in the ...

In this paper, we analyze the condition for complete population inversion by a chirped pulse over a finite duration. The nonadiabatic transition probability is mapped in the two-dimensional parameter space of coupling strength and detuning amplitude. Asymptotic forms of the probability are derived by the interference of nonadiabatic transitions for sinusoidal and triangular pulses. The qualitat...

In the title complex, (C(5)H(6)N)[Cr(CH(4)O(6)P(2))(2)(H(2)O)(2)]·4H(2)O, the Cr(III) atom, lying on an inversion centre, is coordinated by two bidentate methyl-ene diphospho-nate ligands and two water molecules in a distorted octa-hedral coordination geometry. The pyridinium cation is located on an inversion centre, with an N atom and a C atom sharing a position each at a half occupancy. A thr...

Abstract. This paper proposes an iterative technique to reconstruct the source term in transport equations, which account for scattering effects, from boundary measurements. In the two-dimensional setting, the full outgoing distribution in the phase space (position and direction) needs to be measured. In three space dimensions, we show that measurements for angles that are orthogonal to a given...
