Spectropolarimetric Inversions of the Ca ii 8542 Å Line in an M-class Solar Flare [PDF]

Astrophysical Journal, 2018
We study the M1.9-class solar flare SOL2015-09-27T10:40 UT using high-resolution full Stokes imaging spectropolarimetry of the Ca ii 8542 Å line obtained with the CRISP imaging spectropolarimeter at the Swedish 1-m Solar Telescope.

Effects of Solar Proton Events Associated With X-Ray Flares on Near-Earth Electron and Proton Fluxes Based on ZH-1 Satellite Observations

Frontiers in Earth Science, 2022
Solar eruptions can cause violent effects on the space environment. Electromagnetic radiation from solar flares will be the first to arrive on the Earth at the speed of light, followed by solar energetic charged particles.

The exposomal imprint on rosacea: More than skin deep

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Rosacea reflects systemic and environmental interactions, not just a skin disorder. Key factors include environmental triggers, genetic and microbiome influences, diagnostic gaps in skin of colour and social determinants. Advances in multi‐omics and exposome integration highlight pathways towards precision medicine, prevention and equitable, patient ...

Application of the Deep Convolutional Neural Network to the Forecast of Solar Flare Occurrence Using Full-disk Solar Magnetograms

Astrophysical Journal, 2018
In this study, we present the application of the Convolutional Neural Network (CNN) to the forecast of solar flare occurrence. For this, we consider three CNN models (two pretrained models, AlexNet and GoogLeNet, and one newly proposed model). Our inputs

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.

Microwave imaging of quasi-periodic pulsations at flare current sheet

Nature Communications, 2022
Quasi-periodic pulsations (QPPs) are frequently detected in solar and stellar flares, but the underlying physical mechanisms are still to be ascertained.

Research Direction and Science Evaluation: The Role of Coherence and Alignment

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT The decisions of funding agencies greatly influence the direction of scientific research; however, our understanding of how applicants' research directions affect the selection process remains limited. In this study, we investigate how a project's coherence with a scientist's previous work and its alignment with current scientific trends ...

New cases of δ‐aminolevulinic acid dehydratase deficiency: Functional insights into gene variants using an innovative mouse liver model

Journal of Internal Medicine, EarlyView.
Abstract Background Dysfunction of δ‐aminolevulinic acid dehydratase (ALAD), the second enzyme involved in heme biosynthesis, leads to two pathologies: genetic and acquired. The genetic form is an ultrarare, severe childhood‐onset disease inherited in an autosomal recessive manner, whereas the acquired form usually affects adults due to enzyme ...

Quasi-periodic Pulsations in the Most Powerful Solar Flare of Cycle 24 [PDF]

, 2018
Quasi-periodic pulsations (QPPs) are common in solar flares and are now regularly observed in stellar flares. We present the detection of two different types of QPP signals in the thermal emission light curves of the X9.3-class solar flare SOL2017-09 ...
