Non-LTE calculations for neutral Na in late-type stars using improved atomic data

, 2011
Neutral sodium is a minority species in the atmospheres of late-type stars, and line formation in local thermodynamic equilibrium (LTE) is often a poor assumption, in particular for strong lines.

Performance Evaluation of A2-A4-RSRQ and A3-RSRP Handover Algorithms in LTE Network

Jurnal Elektronika dan Telekomunikasi, 2019
In LTE Network, users can move freely in the network through fast and seamless handover (HO). This research focuses on intra-LTE handover which occurs using interface X2 to move an EU between two eNBs, i.e.

Neurodevelopmental assessment at 24 months in infants with esophageal atresia: A prospective cohort study

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective To evaluate neurodevelopment at 24 months in infants surgically treated for esophageal atresia (EA), using the ages and stages questionnaire (ASQ), and identify perinatal and early‐life factors associated with developmental delay. Methods Infants with EA were prospectively enrolled in a structured multidisciplinary follow‐up program.

Non-LTE treatment of molecules in the photospheres of cool stars [PDF]

, 2000
We present a technique to treat systems with very many levels, like molecules, in non-LTE. This method is based on a superlevel formalism coupled with rate operator splitting.

Lunar reference systems and their realisations using INPOP ephemerides

Astronomy & Astrophysics
Context. The definition of a reference system plays a crucial role in quantifying geodetic effects and in surface body cartography. Today, the development and specification of the lunar reference system is stimulated by future space missions, some of ...

Ultrasonic‐assisted extraction of bioactive compounds from eggplant (Solanum melongena L.) calyx and evaluation of extract properties

JSFA reports, EarlyView.
Abstract Background Eggplant (Solanum melongena L.) is widely consumed worldwide and generates considerable waste, including peel and calyx, during processing and consumption. Although often considered as by‐products, these wastes are rich sources of bioactive compounds, which vary depending on the plant variety and cultivation location.

Influence of Inelastic Collisions with Hydrogen Atoms on the Formation of Al I and Si I Lines in Stellar Spectra

, 2016
The non-LTE line formation for Al I and Si I was calculated with model atmospheres corresponding to F-G-K type stars of different metallicity. To account for inelastic collisions with H I, for the first time we applied the cross sections calculated by ...

Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...
