Iteration factors in the line formation problem with frequency dependent source function [PDF]

open access: yesSerbian Astronomical Journal, 2010
In this paper some iteration factors families introduced previously to solve the pure line transfer problem are generalized to the case when the back- ground continuum is taken into account.

The Max-Line-Formation Problem [PDF]

open access: yes, 2021
We consider n robots with limited visibility: each robot can observe other robots only up to a constant distance denoted as the viewing range. The robots operate in discrete rounds that are either fully synchronous (FSync) or semi-synchronized (SSync).

coiling as a linear value for making ceramic wall tiles

open access: yesJournal of Architecture, Art & Humanistic Science, 2021
There are many materials that are used in wall tiles such as marble, granite and other materials used, and ceramic tiles remain the best solution because of its material used in it, which is a clay that has high flexibility, which makes it a rich ...

Mixing state of oxalic acid containing particles in the rural area of Pearl River Delta, China: implications for the formation mechanism of oxalic acid [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
The formation of oxalic acid and its mixing state in atmospheric particulate matter (PM) were studied using a single-particle aerosol mass spectrometer (SPAMS) in the summer and winter of 2014 in Heshan, a supersite in the rural area of the Pearl ...

Stochastic polarized line formation [PDF]

open access: yesAstronomy & Astrophysics, 2006
Summary: The Zeeman effect produced by a turbulent magnetic field or a random distribution of flux tubes is usually treated in the microturbulent or macroturbulent limits where the Zeeman propagation matrix or the Stokes parameters, respectively, are averaged over the probability distribution function of the magnetic field when computing polarized line

Review of Rydberg Spectral Line Formation in Plasmas

open access: yesAtoms, 2023
The present review is dedicated to the problem of an array of transitions between highly-excited atomic levels. Hydrogen atoms and hydrogen-like ions in plasmas are considered here. The presented methods focus on calculation of spectral line shapes. Fast

Planetesimal formation starts at the snow line [PDF]

open access: yes, 2017
Planetesimal formation stage represents a major gap in our understanding of the planet formation process. The late-stage planet accretion models typically make arbitrary assumptions about planetesimals and pebbles distribution while the dust evolution ...

Strong [O iii] λ5007 Compact Galaxies Identified from SDSS DR16 and Their Scaling Relations

open access: yesThe 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.

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

open access: yesJournal 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 ...
