Role of solar flare index in long term modulation of cosmic ray intensity [PDF]

open access: yes
Recently, the importance of the occurrence of solar flares in the long-term modulation of cosmic ray intensity has been re-emphasized. For this purpose, the data of solar flares have been used from various publications, such as Solar Geophysical Data ...

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

open access: yesJournal of Internal Medicine, Volume 299, Issue 1, Page 126-142, January 2026.
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 ...

Long- and Mid-Term Variations of the Soft X-ray Flare Type in Solar Cycles

open access: yes, 2017
Using data from the Geostationary Operational Environmental Satellites (GOES) spacecraft in the 1-8 \AA\ wavelength range for Solar Cycles 23, 24, and part of Cycles 21 and 22, we compare mean temporal parameters (rising, decay times, duration) and the ...

On the Optimal Prediction of Extreme Events in Heavy‐Tailed Time Series With Applications to Solar Flare Forecasting

open access: yesJournal of Time Series Analysis, Volume 47, Issue 1, Page 25-42, January 2026.
ABSTRACT The prediction of extreme events in time series is a fundamental problem arising in many financial, scientific, engineering, and other applications. We begin by establishing a general Neyman–Pearson‐type characterization of optimal extreme event predictors in terms of density ratios.

Ionospheric effects of the extreme solar activity of February 1986 [PDF]

open access: yes
During February 1986, near the minimum of the 11 year Solar sunspot cycle, after a long period of totally quiet solar activity (R sub z = 0 on most days in January) a period of a suddenly enhanced solar activity occurred in the minimum between solar ...

Description and modeling of the Jiddat al Harasis 091 L5 strewn field

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 1, Page 107-121, January 2026.
Abstract With a size of 51.2 × 7.2 km, the 10.9 ± 1.7 ka old Jiddat al Harasis 091 L5 chondrite strewn field is the largest known in Oman. It consists of more than 700 meteorites with a total mass of >4.5 tons from which the largest six stones of >100 kg to 1.5 tons make up two thirds of the total mass.

The Anomalous Temporal Behaviour of Broadband Ly$\alpha$ Emission During Solar Flares From SDO/EVE

open access: yes, 2015
Despite being the most prominent emission line in the solar spectrum, there has been a notable lack of studies devoted to variations in Ly$\alpha$ emission during solar flares in recent years. However, the few examples that do exist have shown Ly$\alpha$

Solar flares and energetic particles [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Solar flares are now observed at all wavelengths from γ -rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares ...
