Statistics of Solar White-light Flares. I. Optimization and Application of Identification Methods
The Astrophysical JournalWhite-light flares (WLFs) are energetic activity in the stellar atmosphere. However, observed solar WLFs are relatively rare compared to stellar WLFs or solar flares observed at other wavelengths, which limits our further understanding of solar/stellar ...

steel research international, EarlyView.H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Barriers to Steel Decarbonization
steel research international, EarlyView.Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

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.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab
Symbolic Interaction, EarlyView.How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

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.

Collective acceleration in solar flares [PDF]
Physica Scripta, 1994 Solar flare data are examined with an eye to seeing if they suggest collective acceleration of ions. That, in fact, seems to be the case. The collective acceleration mechanism of Gershtein is reviewed and the possibilities of the mechanism are discussed.

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 ...
