Correcting the Input Data for Calculating the Asymmetry of Hydrogenic Spectral Lines in Plasmas

Atoms, 2018
We provide corrections to the data in Sholin’s tables from his paper in Optics and Spectroscopy 26 (1969) 27. Since his data was used numerous times by various authors to calculate the asymmetry of hydrogenic spectral lines in plasmas, our corrections ...

Stark Broadening of O I Spectral Lines

Galaxies
We 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 ...

Divergence of Dipole Sums and the Nature of Non-Lorentzian Exponentially Narrow Resonances in One-Dimensional Periodic Arrays of Nanospheres

, 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

Molecular line survey of the high-mass star-forming region NGC 6334I with Herschel/HIFI and the SMA [PDF]

, 2012
We aim at deriving the molecular abundances and temperatures of the hot molecular cores in the high-mass star-forming region NGC 6334I and consequently deriving their physical and astrochemical conditions. In the framework of the Herschel guaranteed time

Photometric redshifts from reconstructed QSO templates [PDF]

, 2001
From SDSS commissioning photometric and spectroscopic data, we investigate the utility of photometric redshift techniques to the task of estimating QSO redshifts. We consider empirical methods (e.g.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

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.
