On the formation of lines in quantum phase space
Journal of Physics A: Mathematical and Theoretical, 2023 Abstract We theoretically study the formation of lines in phase space using Wigner’s distribution W . In trapped quantum systems such lines form generically, crisscrossing phase space

Strong [O iii] λ5007 Compact Galaxies Identified from SDSS DR16 and Their Scaling Relations
The Astronomical Journal, 2023 Green-pea galaxies are a special class of star-forming compact galaxies with strong [O iii ] λ 5007 and considered as analogs of high-redshift Ly α -emitting galaxies and potential sources for cosmic reionization.

Planetesimal formation starts at the snow line [PDF]
, 2017 Context. The formation stage of planetesimals represents a major gap in our understanding of the planet formation process. Late-stage planet accretion models typically make arbitrary assumptions about planetesimal and pebble distribution, while dust ...

Central line-associated bloodstream infections: Effect of patient and pathogen factors on outcome
Journal of Global Infectious Diseases, 2023 Introduction: Patients on central lines are often having multiple morbidities, and invasive devices provide a niche for biofilm formation, which makes central line-associated bloodstream infections (CLABSIs), a serious concern in health-care settings ...

THE FORMATION OF THE Hα LINE IN THE SOLAR CHROMOSPHERE [PDF]
The Astrophysical Journal, 2012 We use state-of-the-art radiation-MHD simulations and 3D non-LTE radiative transfer computations to investigate \Halpha\ line formation in the solar chromosphere and apply the results of this investigation to develop the potential of \Halpha\ as diagnostic of the chromosphere.

Non-LTE LINE FORMATION FOR S I
Odessa Astronomical Publications, 2008 A comprehensive model atom for non-LTE line formation calculations for neutral sulfur in the spectra of F-K stars is presented. All the calculations were made using the 65-level atomic model of S I and Kurucz's atmosphere models with Teff = 5000 ÷ 6500 K,

Cyclotron line formation in a relativistic outflow [PDF]
AIP Conference Proceedings, 1996 There is mounting evidence that, if gamma-ray bursters are Galactic in origin, they are located in a Galactic corona at distances greater than 100 kpc. This has created a need to explore new models of cyclotron line formation. In most previous calculations the line-forming region was modeled as a static slab of plasma, optically thin to continuum ...

FEED CONSUMPTION IN RELATION TO EGG FORMATION AND ENVIRONMENTAL TEMPERATURE IN DANDARAWI AND HY-LINE STRAINS. [PDF]
Journal of Animal and Poultry Production, 2007 A total of one hundred eighty, 40 weeks old from both Dandarawi and Hy-line strains were used in this experiment. Birds within each strain were subdivided into two groups.
