Flaring Activity for Low-mass Stars in the β Pictoris Moving Group

open access: yesThe Astronomical Journal
Stellar flares from K and M dwarfs release panchromatic radiation characterized by a significantly higher brightness temperature (∼9–20 kK) than the star. The increased frequency of magnetic activity on young low-mass stars results in the energy released

Stellar Parameters and Spectroscopic Properties of TESS Objects Observed in the LAMOST Low- and Medium-resolution Spectral Survey

open access: yesThe Astrophysical Journal Supplement Series, 2022
Stellar parameters and magnetic activity are important for the understanding of stellar physics and dynamo theory. We have used LAMOST spectroscopic surveys to study stellar parameters and magnetic activity properties of TESS objects.

Clinical Significance of Therapeutic Drug Level Monitoring for Mycophenolate in Patients With Extrarenal Systemic Lupus Erythematosus—A Systematic Review and Meta‐Analysis

open access: yesArthritis Care &Research, EarlyView.
Objective Clinical response to mycophenolic acid (MPA) is highly heterogeneous; thus, therapeutic drug level monitoring (TDM) may help improve treatment efficacy. This systematic review and meta‐analysis examined therapeutic ranges for MPA levels associated with better outcomes and safety in patients with systemic lupus erythematosus (SLE ...

A Statistical Study of Soft X-Ray Flares on Solar-type Stars

open access: yesThe Astrophysical Journal
The statistical characteristics of stellar flares at optical bands have received extensive study, but they remain to be studied at soft X-ray bands, in particular for solar-type stars.

Trajectories of Physical Function in Canadian Children With Juvenile Idiopathic Arthritis

open access: yesArthritis Care &Research, EarlyView.
Objective We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...

CHROMOSPHERIC ACTIVITY OF THE FLARE STAR YZ CMI IN QUIESCENCE ACCORDING TO THE FAST SPECTRAL MONITORING DATA

open access: yesOdessa Astronomical Publications, 2016
Spectral monitoring of the flare star YZ CMi (U = 12.9, B = 12.7, V = 11.1) was carried out on the Zeiss-600 telescope at the Peak Terskol Observatory. We used a low resolution grating spectrograph with spectral resolution of ~ 100 Å and time resolution ...

The Physics of Flare Stars [PDF]

open access: yesSymposium - International Astronomical Union, 1975
This paper reports the researches of the Texas flare star group. High time resolution and simultaneous photometric, spectroscopic and, if possible, radio observations of flaring stars are essential. Fast and slow flares are distinguished and their distinct optical, spectroscopic, and probably, radio effects are noted.

Building a Framework for Sexual and Reproductive Health Care in the Rheumatology Context: Content and Approaches

open access: yesArthritis Care &Research, EarlyView.
People with systemic autoimmune and rheumatic diseases (SARDs) are at higher risk than the general population of experiencing adverse pregnancy and perinatal outcomes such as preeclampsia, intrauterine growth restriction, and maternal and/or fetal death.

Outlook on Magnetohydrodynamical Turbulence and Its Astrophysical Implications

open access: yesFluids, 2023
Magnetohydrodynamical (MHD) turbulence is ubiquitous in magnetized astrophysical plasmas, and it radically changes a great variety of astrophysical processes.
