Searching for Stellar Activity Cycles Using Flares: The Short- and Long-timescale Activity Variations of TIC-272272592

The Astronomical Journal
We examine 4 yr of Kepler 30 minutes data, and five sectors of Transiting Exoplanet Survey Satellite 2 minutes data for the dM3 star KIC-8507979/TIC-272272592. This rapidly rotating ( P = 1.2 day) star has previously been identified as flare active, with

X-ray activity of the RS CVn-type star σ Gem from the first-year observations of the Einstein Probe

Astronomy & Astrophysics
Context. Stellar flares are energetic events driven by the sudden release of magnetic energy in the stellar atmosphere. Compared to the Sun, the diversity of stellar types and environments leads to a richer variety of flaring phenomena.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

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,

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.

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.

Study of quiescent state X-ray emission from flare stars

, 1986
Quiescent-state X-ray emission of seven flare stars was studied as well as the relationship between the emissions of the chromosphere, transition region and corona.

Annihilation line from the galactic bulge due to action of low-mass flare stars

, 2018
We consider the low-mass flare stars which form the bulk of the population in the galactic bulge as a source of the positrons needed to form the observed narrow annihilation line from the galactic bulge.

From Interferon Signature to the Clinical Landscape: Type I Interferonopathies

Arthritis &Rheumatology, EarlyView.
Objective TypeI interferonopathies are heterogeneous diseases driven by dysregulated type I interferon (IFN‐I) signaling. Diagnosis is challenging due to clinical/molecular variability and the need for IFN‐I quantification. The aim of this study was to characterize the clinical, immunologic, genetic, molecular profiles of patients with suspected ...

Efficacy and Safety of Nanoencapsulated Sirolimus Plus Pegadricase: Results From the Randomized, Placebo‐Controlled Phase 3 Trials

Arthritis &Rheumatology, EarlyView.
Objective DISSOLVE I and II examined the efficacy and safety of nanoencapsulated sirolimus (NAS) plus pegadricase (NASP) in patients with uncontrolled gout (UG). Methods In these double‐blind, placebo‐controlled Phase 3 trials of NASP, patients were randomized 1:1:1 to infusions of high‐dose (HD) or low‐dose (LD) NAS plus pegadricase (HD NASP, LD NASP,
