Temporal Variation of Flare Occurrence Rates via the Spot Evolution on the Sun and Solar-type Stars
The Astrophysical JournalThe spot evolution on the Sun and solar-type stars is important for understanding the nature of consequential flaring activity. This study statistically investigates the variance of flare occurrence rate through the time evolution of spots on the Sun and

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.

Analysis of Solar-like X-class Flare on Wolf 359 Observed Simultaneously with TESS and XMM-Newton
The Astrophysical Journal, 2023 We present an analysis of a flare on the Wolf 359 star based on simultaneous observations of Transiting Exoplanet Survey Satellite and XMM-Newton. A stellar flare with energy comparable to an X-class solar flare is analyzed on this star for the first ...

VIEW, EarlyView.Plant‐derived nanovesicles (PDNVs) are naturally secreted by fruit, vegetables, seeds, leaves and other natural sources. Used as drug delivery systems, they can combine intrinsic therapeutic activity, enhanced skin permeation and cargo‐carrying capacity, suitable for dermatological and cosmetic applications including hydration, antioxidant/anti ...

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 ...

One-Minute Quasi-Periodic Pulsations during an M-Class Solar Flare
, 2022 We study the Quasi-Periodic Pulsations (QPPs) of an M4.4 class solar flare, which occurred in active region NOAA 11165 on 8 March 2011. With the Fast Fourier Transform (FFT) method, we decompose the flare light curve into fast- and slowly-varying ...

Forecasting the Remaining Duration of an Ongoing Solar Flare
Space Weather, 2021 The solar X‐ray irradiance is significantly heightened during the course of a solar flare, which can cause radio blackouts due to ionization of the atoms in the ionosphere.
