Multifilter Time-series Observations of Eleven Blue Short-period ATLAS Variable Stars

The Astronomical Journal, 2023
Eleven periodic variable stars were observed photometrically through two to four filters from the set UBVR _C I _C . Phase-folded data for each star cover full cycles of variation.

The History Goes On: Century Long Study of Romano’s Star

Galaxies, 2019
GR 290 (M 33 V0532 = Romano’s Star) is a unique variable star in the M33 galaxy, which simultaneously displays variability typical for luminous blue variable (LBV) stars and physical parameters typical for nitrogen-rich Wolf-Rayet (WR) stars (WN ...

Current stage of studies of the star configurations at intermediate energies with the use of the BINA detector

SciPost Physics Proceedings, 2020
The Space Star Anomaly in proton-deuteron breakup cross-section occurs at energies of about 10 MeV. Data for higher energies are sparse. Therefore, a systematic scan over star configurations in the range of intermediate energies between 50 and 100 MeV ...

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.
