Collective acceleration in solar flares [PDF]
Physica Scripta, 1994 Solar flare data are examined with an eye to seeing if they suggest collective acceleration of ions. That, in fact, seems to be the case. The collective acceleration mechanism of Gershtein is reviewed and the possibilities of the mechanism are discussed.

Do Financialization and Innovation Enhance Environmental Sustainability in Sub‐Saharan Africa?
Thunderbird International Business Review, EarlyView.ABSTRACT This study addresses the perception of Sub‐Saharan Africa (SSA) as a region with limited financial capabilities and technological advancement to enhance environmental sustainability. Conducted across 24 SSA countries from 2000 to 2021, the research employs instrumental IV and panel quantile regressions.

High-resolution Observations of a C9.3 White-light Flare and Its Impact on the Solar Photosphere
The Astrophysical Journal LettersWe present a detailed analysis of a C9.3 white-light flare using high-resolution observations from the New Vacuum Solar Telescope. The flare occurred near the eastern solar limb on 2023 September 11, within NOAA AR 13431, and produced beam electrons with

SCATTERING POLARIZATION IN SOLAR FLARES [PDF]
The Astrophysical Journal, 2013 There is an ongoing debate about the origin and even the very existence of a high degree of linear polarization of some chromospheric spectral lines observed in solar flares. The standard explanation of these measurements is in terms of the impact polarization caused by non-thermal proton and/or electron beams.

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...

The White-light Emissions in Two X-class Flares Observed by ASO-S and CHASE
The Astrophysical Journal LettersThe white-light continuum emissions in solar flares (i.e., white-light flares) are usually observed on the solar disk but, in a few cases, off the limb.

Solar Flare Intensity Prediction With Machine Learning Models
Space Weather, 2020 We develop a mixed long short‐term memory (LSTM) regression model to predict the maximum solar flare intensity within a 24‐hr time window 0–24, 6–30, 12–36, and 24–48 hr ahead of time using 6, 12, 24, and 48 hr of data (predictors) for each Helioseismic ...

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT
Meteoritics &Planetary Science, EarlyView.Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

FEATURES OF THE DEVELOPMENT OF A CIRCULAR SOLAR FLARE
Odessa Astronomical Publications, 2020 We present the results of the analysis of morphology and evolution of the circular solar flare using H-alpha images. H-alpha filtergrams were obtained with the Meudon spectroheliograph.
