Journal 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 ...

High Power Laser Science and Engineering, 2013 The driving mechanism of solar flares and coronal mass ejections is a topic of ongoing debate, apart from the consensus that magnetic reconnection plays a key role during the impulsive process.

Journal 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.

Fine structure events in microwave emission during solar minimum
Solar-Terrestrial Physics, 2019 The solar minimum is a period with a relatively smaller number of sunspots and solar eruptions, and has been less studied before. Since the radio signal rapidly responds to the change of solar plasma and magnetic field, we perform a comprehensive ...

Embracing the politics of transformation: Policy action as “battle‐settlement events”
Review of Policy Research, Volume 43, Issue 1, January 2026.Abstract Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations.

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

Solar Energetic Particle Events During May 2024 Geomagnetic Superstorm
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Three solar energetic particle (SEP) events originating from solar active region 13664 occurred on 10–16 May 2024, coinciding with a geomagnetic superstorm. Using data from the Geostationary Operational Environmental Satellites and Meteorological Operational satellite‐C, we investigate the energetic proton fluxes and east‐west flux ratios in ...
