Solar energetic particle events: phenomenology and prediction
, 2002 Solar energetic particle events can cause major disruptions to the operation of spacecraft in earth orbit and outside the earth's magnetosphere and have to be considered for EVA and other manned activities. They may also have an effect on radiation doses

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models
Methods in Ecology and Evolution, EarlyView.Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

Conditions for arrival of solar energetic protons in Earth after strong solar flares
Solar-Terrestrial Physics, 2022 We analyze the Sun-to-Earth transport of energetic protons accelerated in solar flares. We use a model which assumes that protons move earthward in the Parker electromagnetic field.

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 ...

MHD simulations of coronal heating [PDF]
, 2015 The problem of heating the solar corona requires the conversion of magnetic energy into thermal energy. Presently, there are two promising mechanisms for heating the solar corona: wave heating and nanoflare heating.

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.

Management of chronic urticaria: Current status and future prospect
Journal of the European Academy of Dermatology and Venereology, EarlyView.Chronic urticaria is driven by mast cell activation through autoimmune, inflammatory, and neuroimmune pathways. A structured approach combining diagnosis, patient‐reported outcomes, stepwise therapy, treatment optimization, monitoring and emerging targeted agents may improve disease control and enable more personalized management.

The Efficiency of Electron Acceleration during the Impulsive Phase of a Solar Flare
The Astrophysical Journal Letters, 2023 Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in solar flare (and similar astrophysical settings) presents a major challenge.
