Patients' perspectives on flares in knee osteoarthritis: a qualitative study

, 2020
Purpose: Acute flares in osteoarthritis may be an important, although poorly understood part of its natural history. Despite an OMERACT working group recently proposing a preliminary definition of acute flare in OA there is still uncertainty around ...

Shock Cooling and Breakout Emission for Optical Flares Associated with Gravitational-wave Events

The Astrophysical Journal
The astrophysical origin of stellar-mass black hole (BH) mergers discovered through gravitational waves (GWs) is widely debated. Mergers in the disks of active galactic nuclei (AGNs) represent promising environments for at least a fraction of these ...

Flares on active M-type stars observed with XMM-Newton and Chandra. [PDF]

, 2007
M-type red dwarfs are among the most active stars. Their light curves display random variability of rapid increase and gradual decrease in emission.

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,

Magnetic Field Amplification and Blazar Flares

EPJ Web of Conferences, 2013
Recent multiwavelength observations of PKS 0208-512 by SMARTS, Fermi, and Swift revealed that γ-ray and optical light curves of this flat spectrum radio quasars are highly correlated, but with an exception of one large optical flare having no ...

Results from Optical and UV Stellar Flare Spectroscopy [PDF]

International Astronomical Union Colloquium, 1983
ABSTRACTOptical and ultraviolet spectroscopy can enable the assessment of the physical conditions characterizing a stellar flare atmosphere and thereby potentially elucidate the possible radiative and hydrodynamic transport mechanisms operative during stellar flares.

Expert Perspectives: Defining and Managing Progressive Pulmonary Fibrosis in Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Systemic sclerosis–associated interstitial lung disease (SSc‐ILD) is one of the leading causes of morbidity and mortality in SSc, affecting up to three‐quarters of patients. The disease course is highly heterogeneous, ranging from indolent, nonprogressive forms to rapidly progressive pulmonary fibrosis (PPF).

Flaring Behavior in the M Dwarf PM J11183+1347 from TESS Observations

The Astrophysical Journal
This study presents analysis of the flaring properties and magnetic activity of an M dwarf PM J11183+1347 based on photometry light curves from the Transiting Exoplanet Survey Satellite (TESS) mission. PM J11183+1347 is an active flaring star of dMe type,
