On the formation of lines in quantum phase space
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

Central line-associated bloodstream infections: Effect of patient and pathogen factors on outcome
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]
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.

Line formation in the wind of Alpha Cygni [PDF]
AbstractWe summarize the results of recent IUE observations of the spectra of α Cygni and discuss possible explanations for the Doppler-shifted pure absorption profiles in the resonance lines of the singly ionized metals. The results of detailed modeling for MgII λ 2795, 2802 are presented, and discussed in the context of observations of α Cyg in the ...

Non-LTE LINE FORMATION FOR S I
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,

FEED CONSUMPTION IN RELATION TO EGG FORMATION AND ENVIRONMENTAL TEMPERATURE IN DANDARAWI AND HY-LINE STRAINS. [PDF]
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.

A Note on the Formation of Stellar Absorption Lines [PDF]
Microphotometer measures of the total absorptions of lines of O II within the wing of Hγ, and of CaH within the wing of HЄ, show departures from the normal absorptions predicted from the multiplet intensities of these lines. The departures increase with the wing absorption, but the effect is more pronounced for O II than for CaH.

LINE FORMATION IN SPECTRA OF X-RAY NOVAE
Results of X-ray Novae (XN) optical spectra computation are presented. The continuum and Balmer line are calculated. The model of XN as a self-irradiated accretion disk is used.

LIMpy: A Semianalytic Approach to Simulating Multiline Intensity Maps at Millimeter Wavelengths
Mapping of multiple lines such as the fine-structure emission from [C ii ] (157.7 μ m), [O iii ] (52 and 88.4 μ m), and rotational emission lines from CO are of particular interest for upcoming line intensity mapping (LIM) experiments at millimeter ...

Cyclotron line formation in a relativistic outflow [PDF]
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 ...
