Abstract The electrostatic theory of surface magnetoplasmons on a semi-infinite magnetized electron gas is generalized to mixed Faraday–Voigt configurations. We analyze type waves that strongly direction-dependent, and may be realized narrow-gap semiconductors in the THz regime. A general expression for dispersion relation presented, with its dependence magnitude orientation applied magnetic fi...

A graph G is L-list colorable if for a given list assignment L= {L(v): v ∈ V }, there exists a proper coloring c of G such that c(v) ∈ L(v) for all v ∈ V . If G is L-list colorable for any list assignment with |L(v)| k for all v ∈ V , then G is said k-choosable. In [M. Voigt, A not 3-choosable planar graph without 3-cycles, Discrete Math. 146 (1995) 325–328] and [M. Voigt, A non-3choosable plan...

Diffraction-line broadening routes are briefly reviewed. Both laboratory and synchrotron xray measurements of W and MgO showed that a Voigt function satisfactorily fits the physically broadened line profiles. The consequences of an assumed Voigt-function profile shape for both sizebroadened and strain-broadened profiles (“double-Voigt” method) are studied. It is shown that the relationship betw...

A Voigt profile function emerges in several physical investigations (e.g. atmospheric radiative transfer, astrophysical spectroscopy, plasma waves and acoustics) and it turns out to be the convolution of the Gaus-sian and the Lorentzian densities. Its relation with a number of special functions has been widely derived in literature starting from its Fourier type integral representation. The mai...

In this paper it is shown that the change in the energy for a linearly viscoelastic body (with Kelvin–Voigt type viscosity) in frictionless contact with a rigid obstacle can be accounted for by viscous losses and the work done by external forces. Thus there is no change in the energy due to impacts, unlike the case of rigid-body dynamics. The result can be extended to a wide class of dynamic vi...

A Voigt function is the convolution of a Gaus-sian and a Cauchy, or Lorentzian, density. The computation of these functions is required in problems arising in a variety of subjects such as nuclear reactors, atmospheric transmittance, and spectroscopy. This letter presents a new series for the approximate computation of Voigt functions. The derivation is accomplished using straightforward Fourie...

Adina Preda and Kristin Voigt should be commended for bridging the gap between moral philosophy and health policy. While I am convinced by much of their analysis of what they call the Health Equity as Social Change (HESC) model, I am not certain they are correct to claim that " in the HESC model, 'avoidability' appears as both a necessary and sufficient condition for health inequity " (Preda an...

Rapid calculation of the Voigt profile is critical for high performance in computational spectropolarimetric analysis. The Curtis and Osborne approximation to the Voigt function is arithmetically dense and embarrassingly parallel which makes it an intriguing candidate for exploiting accelerator technologies. We implement versions for the Cell Broadband Engine and for an NVIDIA GPU, and compare ...
