Cloud Opacity Variations from Nighttime Observations in Venus Transparency Windows
AtmosphereThe thick cloud layer enshrouding Venus influences its thermal balance and climate evolution. However, our knowledge of total optical depth, spatial and temporal variations in the clouds is limited.

Scattering line polarization in rotating, optically thick disks
, 2014 To interpret observations of astrophysical disks it is essential to understand the formation process of the emitted light. If the disk is optically thick, scattering dominated and permeated by a Keplerian velocity field, Non-Local Thermodynamic ...

Opacity effects on the radiative losses of coronal loops
The Astrophysical Journal, 1991 This paper presents calculations of radiative losses, which include the effects of geometry and optical depth, that can be used to improve the energy losses in many flux-tube calculations for loops with constant and variable cross sections. The results include the non-LTE ionization state of hydrogen and helium, thus allowing the determination of the ...

A Porosity-Length Formalism for Photon-Tiring-Limited Mass Loss from Stars Above the Eddington Limit
, 2004 We examine radiatively driven mass loss from stars near and above the Eddington limit (Ledd). We begin by reviewing the instabilities that are expected to form extensive structure near Ledd.

Advanced Science, EarlyView.An intermolecular AIDF strategy enables an organic X‐ray scintillator (OXST) that resists concentration quenching and efficiently utilizes singlet and triplet excitons. The AIDF emitter, embedded in a polysulfone matrix, yields bright, flexible, and transparent scintillation screens with ultralow detection limits and high spatial resolution, offering a

Extracting Physical Information from the Voigt Profile Using the Lambert W Function
PlasmaSpectral line shapes are a key ingredient of hot-plasma opacity calculations. Since resorting to elaborate line-shape models remains prohibitive for intensive opacity calculations involving ions in different excitation states, with L, M, etc., shells are

A Constrained Dust Opacity for Models of Dense Clouds and Protostellar Envelopes
Research Notes of the AASRadiative transfer models of dense clouds and protostellar envelopes rely on the availability of appropriate dust opacities, particularly as new JWST data become available.

Advanced Science, EarlyView.Dysregulated TCA cycle contributes to Alzheimer's disease (AD) pathogenesis. Here, we show that microglial isocitrate dehydrogenase 1 (IDH1) is a critical driver. Elevated IDH1 disrupts citrate metabolism and mitochondrial function, exacerbating AD pathology.
