Stark broadening of N II spectral lines [PDF]
Serbian Astronomical JournalThe Stark broadening parameters, widths, and shifts, for spectral lines within the 45 N II multiplets, were calculated for collisions with electrons, protons and helium ions, by using the semiclassical perturbation method. The obtained data were

Stark Widths of Na IV Spectral Lines
Atoms, 2017 Sodium is a very important element for the research and analysis of astrophysical, laboratory, and technological plasmas, but neither theoretical nor experimental data on Stark broadening of Na IV spectral lines are present in the literature.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Solar Fe abundance and magnetic fields - Towards a consistent reference metallicity
, 2012 We investigate the impact on Fe abundance determination of including magnetic flux in series of 3D radiation-MHD simulations of solar convection which we used to synthesize spectral intensity profiles corresponding to disc centre. A differential approach

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

BM ORI: SEARCH FOR SECONDARY SPECTRAL LINES
Odessa Astronomical Publications, 2017 The search for the secondary spectral lines was made by using special high signal/noise ratio emulsion A700u. The four spectra (two near elongations and two near conjunctions) were obtained with 6-m telescope (BTA), dispersion is 26 Å/mm. We searched the

Identification of phase-independent spectral lines in close binary V455 CYG: I. Telluric lines [PDF]
Serbian Astronomical Journal, 2007 Spectroscopic observations of close binary star V455 Cygni reveal many lines that originate in interstellar and circumstellar medium and the atmosphere of the Earth; we found over two hundred such spectral features, and in this paper we present the list
