Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Light Echoes of Time-resolved Flares and Application to Kepler Data

The Open Journal of Astrophysics
Light echoes of stellar flares provide an intriguing option for exploring protoplanetary disks in young stellar systems. Previous work on light echoes of circumstellar disks made use of delta-function flares for modeling.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Simulating the impact of stellar flares on the climate and habitability of terrestrial Earth–like exoplanets

, 2023
Stellar flares present challenges to the potential habitability of terrestrial planets orbiting M dwarf stars through inducing changes in the atmospheric composition and irradiating the planet's surface in large amounts of ultraviolet light.

Effects of Ultraviolet Radiation on Sub-Neptune Exoplanet Hazes through Laboratory Experiments

The Planetary Science Journal
Temperate sub-Neptune exoplanets could contain large inventories of water in various phases, such as water worlds with water-rich atmospheres or even oceans.

Abundance variations and first ionization potential trends during large stellar flares

, 2008
Context. In the solar corona, elements of low first ionization potential (FIP $\la$ 10 eV) are enriched relative to their abundances in the photosphere, while high-FIP abundances remain unchanged. This was labeled as the Solar FIP effect. High-resolution

Impact of Early Antimalarial Adherence on Future Acute Care Utilization and Cost Among Patients With Rheumatoid Arthritis and Systemic Lupus Erythematosus: A Population‐Based Study

Arthritis &Rheumatology, EarlyView.
Objective To assess the association between early antimalarial adherence and future acute care utilization and cost in a population‐based cohort of incident rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Methods All patients with incident RA/SLE and new antimalarial use in British Columbia, Canada, between January 1997 and March 2022

High-time-cadence Spectroscopy and Photometry of Stellar Flares on M-dwarf YZ Canis Minoris with Seimei Telescope and TESS. II. Statistical Properties of Blue/Red Asymmetries in the Hα Line

The Astrophysical Journal
M-dwarfs frequently produce flares, and their associated coronal mass ejections (CMEs) may threaten the habitability of close-in exoplanets. M-dwarf flares sometimes show prominence eruption signatures, observed as blue/red asymmetries in the H α line ...
