MODELING OF RESONANCE EFFECTS IN SPINE WITH ADDITIONAL FIXING ELEMENTS [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2019 Subject of Research. We study the procedure of natural frequencies calculation for a system consisting of a human spine with fixing elements. Resonant effects can occur in the vicinity of such system leading to stability violation or structure ...

Resonant Absorption in the AGN spectra emerging from photoionized gas: differences between steep and flat ionizing continua [PDF]
, 1998 We present photoionization models accounting for both photoelectric and resonant absorption. Resonance absorption lines from C, O, Ne, Mg, Si S and Fe between 0.1 and 10 keV are treated.

Atomic-scale surface demixing in a eutectic liquid BiSn alloy [PDF]
, 2005 Resonant x-ray reflectivity of the surface of the liquid phase of the Bi$_{43}$Sn$_{57}$ eutectic alloy reveals atomic-scale demixing extending over three near-surface atomic layers. Due to the absence of underlying atomic lattice which typically defines

Calibration and limitations of a fixed-partly fixed resonant column apparatus [PDF]
E3S Web of ConferencesThe small-strain shear modulus of soils and rocks is an important input parameter in geotechnical analyses. Its estimation using the resonant column apparatus relies on accurate knowledge of the rotational inertia of the apparatus’s active end.

Formation of phase lags at the cyclotron energies in the pulse profiles of magnetized, accreting neutron stars [PDF]
, 2014 Context: Accretion-powered X-ray pulsars show highly energy-dependent and complex pulse-profile morphologies. Significant deviations from the average pulse profile can appear, in particular close to the cyclotron line energies.
