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 dust origin of the Broad Line Region and the model consequences for AGN unification scheme [PDF]
, 2015 We propose a very simple physical mechanism responsible for the formation of the Low Ionization Line part of the Broad Line Region in Active Galactic Nuclei.

Stark Broadening of Neutral Boron Lines
Atoms, 2019 Stark broadening parameters, width and shift, of lines within B I 2s22p−2s2ns spectral series have been calculated. Semi-classical theory in impact approximation has been applied. Temperature dependence of Stark parameters has been studied.

Counting Critical Formations on a Line
SIAM Journal on Control and Optimization, 2014 Formation shape control for a collection of point agents is concerned with devising decentralized control laws which ensure that the formation will move so that certain interagent distances approximate prescribed values as closely as possible.

Animation of Flocks Flying in Line Formations [PDF]
Artificial Life, 2011 We provide a biologically motivated technique for modeling and animating bird flocks in flight, which produces plausible and realistic-looking flock animations. While most previous approaches have focused on animating cluster formations, this article introduces a technique for animating flocks that fly in certain patterns, so-called line formations. We

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

Constraining the Star Formation Histories of Spiral Bulges [PDF]
, 1999 Long-slit spectroscopic observations of line-strengths and kinematics made along the minor axes of four spiral bulges are reported. Comparisons are made between central line-strengths in spiral bulges and those in other morphological types.

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.

Line formation in the wind of Alpha Cygni [PDF]
International Astronomical Union Colloquium, 1981 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 ...

Evolution of the Most Massive Galaxies to z ~ 0.6: II. The link between radio AGN activity and star formation [PDF]
, 2012 We analyze the optical spectra of massive (log M*/Msun > 11.4) radio-loud galaxies at z~0.2 and z~0.6. By comparing stellar population parameters of these radio-loud samples with radio-quiet control samples, we investigate how the presence of a radio ...
