Multiple Generation Star Formation in Cepheus Flare

The Astronomical Journal
We present an analysis of the young stellar moving group ASCC 127 using Gaia DR3 data, significantly expanding its membership to 3971 stars—double the number identified in previous studies.

Flare in Late-type Stars: UV [PDF]

International Astronomical Union Colloquium, 1995
Early studies of stellar flares were made entirely in the optical regime. It was recognised that flares arose from the generation of hot plasma within the stellar chromosphere at whose temperature (indicated, for instance, by the presence of a strong, blue optical continuum) a substantial emission in the ultraviolet would be expected.

Formation of Light‐Emitting Defects in Ag‐Based Memristors

Advanced Electronic Materials, EarlyView.
How does a memristor begin to emit light‐before it even conducts? This work reveals that nanoscale silver clusters form, diffuse, and aggregate during activation, driving early photoluminescence ahead of current flow. Linking these precursor dynamics to later electroluminescence, it uncovers the origins of light emission and enables precise control of ...

Time-dependent Stellar Flare Models of Deep Atmospheric Heating

The Astrophysical Journal
Optical flares have been observed from magnetically active stars for many decades; unsurprisingly, the spectra and temporal evolution are complicated.

Flare activity of stars in the Taurus region [PDF]

Symposium - International Astronomical Union, 1990
Using the actual observational data on photometric and spectral stellar activity in the region of central area of the Taurus Dark Clouds complex, the question of flare activity of the stars and its connection with another kinds of activities is considered.

Flare Activity Among Nearby Stars [PDF]

International Astronomical Union Colloquium, 1995
I selected the common objects from our Data Base on 234 UV Cet Flare Stars and Related Objects and the Third Catalogue of Nearby Stars by Gliese & Jahreiss (CNS-3). It is found that manifestation of flare activity (FA) (flares in any spectral region or photometric variability caused by spots) is observed on 143 flare stars (FS) out of the 3803 CNS ...

Systemic Corticosteroids in the Management of Sinonasal Disease: An Evidence‐Based Expert Review

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a prevalent, heterogeneous inflammatory disease associated with significant morbidity. Systemic corticosteroids (SCS) are commonly prescribed for their anti‐inflammatory effects, but cumulative exposure carries risks, including metabolic, cardiovascular, and skeletal complications.

Magnetic Activity in M-type Stars Based on LAMOST DR11 and TESS Observations

The Astrophysical Journal Supplement Series
We have used 898,351 M-type stellar spectra released by Large Sky Area Multi-Object Fiber Spectroscopic Telescope DR11 to calculate the equivalent width of the Ca II infrared triplet (IRT) lines, the residual chromospheric emission, and the parameter ${R}

Chronic Rhinosinusitis and Nasal Polyps in Eosinophilic Granulomatosis With Polyangiitis: A Scoping Review

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is one of the most common manifestations of eosinophilic granulomatosis with polyangiitis (EGPA), often preceding the diagnosis of systemic vasculitis by several years. The sinonasal presentation of EGPA typically resembles CRS with nasal polyps (CRSwNP), making it clinically indistinguishable from those
