Radiative Transfer with Opacity Distribution Functions: Application to Narrowband Filters [PDF]

The Astrophysical Journal Supplement Series, 2021
Abstract Modeling of stellar radiative intensities in various spectral passbands plays an important role in stellar physics. At the same time, direct calculation of the high-resolution spectrum and then integration of it over the given spectral passband is computationally demanding due to the vast number of atomic and molecular lines ...

Generation of a sharp density increase in radiation transport between high-Z and low-Z plasmas

Matter and Radiation at Extremes, 2016
A sharp density increase (referred to as density incrustation) of the Au plasmas in the radiative cooling process of high-Z Au plasmas confined by low-Z CH plasmas is found through the radiative hydrodynamic simulations.

The Inhomogeneity Effect. I. Inhomogeneous Surface and Atmosphere Accelerate Planetary Cooling

The Astrophysical Journal, 2023
We propose a general principle that under radiative-convective equilibrium, the spatial and temporal variations in a planet’s surface and atmosphere tend to increase its cooling.

Radiative accelerations of nickel from new monochromatic opacities

Astronomy & Astrophysics
Context. Radiative accelerations express the transfer of momentum from the radiation field to the various chemical species of the stellar medium. They are evaluated from the monochromatic cross-sections of each element given the local thermodynamical ...

Quantum Molecular Dynamics calculations of radiative opacities [PDF]

Astronomy & Astrophysics, 2003
We show that Quantum Molecular Dynamics provides a powerful tool to extend and benchmark current opacities libraries into the complex regime of warm dense matter. In this regime, the medium can be constituted of electrons, protons, atoms and molecules, while plasma and many-body effects can not be treated as perturbations.

Observational estimates of radiative forcing due to land use change in southwest Australia [PDF]

, 2007
Radiative forcing associated with land use change is largely derived from global circulation models (GCM), and the accuracy of these estimates depends on the robustness of the vegetation characterization used in the GCMs.

Observations of diurnal and spatial variability of radiative forcing by equatorial deep convective clouds [PDF]

, 2004
From geostationary satellite observations of equatorial Africa and the equatorial east Atlantic during May and June 2000 we explore the radiative forcing by deep convective cloud systems in these regions. Deep convective clouds (DCCs) are associated with

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

XTRUDE: A Process‐Informed Framework for High‐Fidelity Analysis of Hydrogel Extrusion

Advanced Functional Materials, EarlyView.
Extrusion performance emerges from the interplay between material properties and processing conditions. XTRUDE (eXTrusion Rheology for Understanding and Defining Extrudability) recreates the extrusion environment with in situ pressure and temperature sensing, enabling characteristic pressure signatures to quantify extrusion‐specific phenomena and ...
