Stellar flares in TESS photometry

Stellar magnetic activity causes different observable phenomena on the surface of a star, including starspots, bright regions, and even explosive events, such as flares and coronal mass ejections.

Solar and stellar flares: implication on the similar physical mechanisms

, 2016
In this talk, we briefly reviewed and compared various aspects of solar and stellar flares. The results imply the similar physical mechanisms of the two phenomena.

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.

Li production by stellar flares in young open clusters

, 2008
The correlation observed between the Li abundance and surface activity of young cool stars is not explained by current stellar evolution models. We study the possibility that this correlation arises from significant in situ production of Li by solar-like

Validation of International Classification of Diseases Code–Based Case Definitions of Immune Checkpoint Inhibitor–Associated Inflammatory Arthritis From Administrative Health Data

Arthritis &Rheumatology, EarlyView.
Objective Immune checkpoint inhibitors (ICIs) for cancer can lead to immune‐related adverse events, including ICI‐associated inflammatory arthritis (ICI‐IA). There are no validated International Classification of Diseases (ICD) code–based case definitions for ICI‐IA.

Immune Complexes Shape the Pathogenicity of Autoantibodies in Systemic Autoimmune Diseases: Insights From an FcγRIIIA‐Reporter Assay

Arthritis &Rheumatology, EarlyView.
Objective Immune complexes (ICs), formed by autoantigen and autoantibody, play a pathogenic role in systemic autoimmune diseases through stimulation of Fcγ receptors (FcγR). However, studies investigating bioactivity of circulating ICs across various diseases remain limited.

Sub-second cadence structure of optical flares on AD Leo

Astronomy & Astrophysics
Context. Stellar flares are sudden brightenings caused by magnetic reconnection and are frequently observed on late-type stars. High-cadence photometry of flares provides valuable insights into the mechanisms of these events, yet such observations remain

A Pragmatic Trial of a Shared Decision‐Making Intervention to Improve Medication Adherence and Outcomes in Systemic Lupus Erythematosus: The HCQ‐SAFE Study

Arthritis &Rheumatology, EarlyView.
Objective Hydroxychloroquine (HCQ) nonadherence in systemic lupus erythematosus (SLE) stemming from decision complexities can be improved with shared decision‐making (SDM) tools clarifying benefits and harms. This study aimed to develop and evaluate HCQ‐SAFE, a pictogram‐based SDM tool during SLE visits.
