Stark Broadening of In III Lines in Astrophysical and Laboratory Plasma
Open Astronomy, 2011 In the deeper layers of hot stellar photospheres the Stark widths of spectral lines can be comparable and even larger than the thermal Doppler widths.

Stark Broadening of O I Spectral Lines
GalaxiesWe do not know a priori chemical composition of a star. However, with more high resolution spectra becoming more abundant thanks to the development of space-born observations, atomic data including Stark broadening parameters for various spectral lines ...

, 2005 Origin and properties of non-Lorentzian spectral lines in linear chains of nanospheres are discussed. The lines are shown to be super-exponentially narrow with the characteristic width proportional to exp[-C(h/a)^3] where C is a numerical constant, h the

Spitzer spectral line mapping of supernova remnants: I. Basic data and principal component analysis [PDF]
, 2007 We report the results of spectroscopic mapping observations carried out toward small (1 x 1 arcmin) regions within the supernova remnants W44, W28, IC443, and 3C391 using the Infrared Spectrograph of the Spitzer Space Telescope.

Partial Paschen-Back splitting of SiII and SiIII lines in magnetic CP stars
, 2012 Modelling of the spectra of magnetic A and B main sequence stars is generally done assuming that all the lines are split by the magnetic field according to the Zeeman effect.

Two-oscillator model of trapped-modes interaction in a nonlinear bilayer fish-scale metamaterial
, 2014 We discuss the similarity between the nature of resonant oscillations in two nonlinear systems, namely, a chain of coupled Duffing oscillators and a bilayer fish-scale metamaterial.

The molecular emission-line spectrum of IRC +10216 between 330 and 358 GHz [PDF]
, 1994 We have conducted a spectral line survey of IRC + 10216 using the Caltech Submillimeter Observatory to an average sensitivity of ≾95 mK. A deconvolution algorithm has been used to derive the continuous single-sideband spectrum from 330.2 to 358.1 GHz ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

LAWS IN BEHAVIOUR OF NonLTE EFFECTS FOR THE NaI AND Mgl ATOMS FOR K - A STARS
Odessa Astronomical Publications, 2017 NonLTE calculations for the Nal and Mgl atoms were performed for model atmospheres of Tef= 4000 - 12000K. logg = 0.0 - 4.5, [NI/H] = 0.5- (-4). Departures from LTE result in strengthening the Nal spectral lines and weakening the Mgl ones.
