Solar Flare Electron Spectra at the Sun and near the Earth
The Astrophysical Journal, 2007 We compare hard X-ray (HXR) photon spectra observed by the RHESSI with the spectra of the electrons in the associated solar impulsive particle events observed near 1 AU by the WIND 3D Plasma and Energetic Particle (3DP) instrument. For prompt events, where the inferred injection time at the Sun coincides with the HXR burst, the HXR photon power-law ...

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.

Power-law Indices of EUV Intensity Power Spectrum in Flaring Coronal Active Regions
The Astrophysical JournalSolar intensity power spectra are usually characterized by colored noise, with the spectral energy following a segmented power-law function of frequency, S ( f ) ∝ f ^− ^α , over different frequency ranges. Typically, the power-law index exceeds 1 in the

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 ...

Energetic proton spectra in the 11 June 1991 solar flare [PDF]
, 2000 We have studied a subset of the 11 June 1991 solar flare γ-ray data that we believe arise from soft proton or ion spectra. Using data from the COMPTEL instrument on the Compton Observatory we discuss the gamma-ray intensities at 2.223 MeV, 4–7 MeV, and 8–

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.

Meteoritics &Planetary Science, EarlyView.Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Quasi-Periodic Pulsations in an M-Class Solar Flare
, 2023 We have studied the quasi-periodic pulsations (QPPs) of the M2.3 flare that occurred in the active region NOAA 12172 on 23 September 2014. Through the fast Fourier transform (FFT) method, we decompose the flare light curves into fast- and slowly-varying ...
