Multi-wavelength Observations of Two Explosive Events and Their Effects on the Solar Atmosphere [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
We investigated two flares in the solar atmosphere that occurred on June 3, 2012 and July 6, 2012 and caused propagation of Moreton and EIT waves. In the June 3 event, we noticed a filament winking which presumably was caused by the wave propagation ...

Pseudoprogression after advanced first-line endocrine therapy in metastatic breast cancer with bone metastasis: A case report

open access: yesFrontiers in Oncology, 2023
Approximately 75% of patients with advanced breast cancer develop bone metastasis, which significantly affects both the quality of life and the survival rate of patients. Accurate determination of the status of bone metastases is important for developing

The Optical Flare [PDF]

open access: yesSolar Physics, 1983
Optical observationd now present considerable information on the flare process. It is always associated with filaments and with simplification of existing magnetic connections, and it arises from the emergence and expansion of new flux.

A FLARE IN THE JET OF PICTOR A [PDF]

open access: yesThe Astrophysical Journal, 2010
A Chandra X-ray imaging observation of the jet in Pictor A showed a feature that appears to be a flare that faded between 2000 and 2002. The feature was not detected in a follow-up observation in 2009. The jet itself is over 150 kpc long and a kpc wide, so finding year-long variability is surprising.

Particle Acceleration Driven by Null Electromagnetic Fields Near a Kerr Black Hole

open access: yesUniverse, 2020
Short timescale variability is often associated with a black hole system. The consequence of an electromagnetic outflow suddenly generated near a Kerr black hole is considered assuming that it is described by a solution of a force-free field with a null ...

Validation of the SMOS Mission for Space Weather Operations: The Potential of Near Real‐Time Solar Observation at 1.4 GHz

open access: yesSpace Weather, 2021
Soil Moisture and Ocean Salinity (SMOS) is an ESA mission observing Earth at 1.4 GHz with full polarimetry. SMOS images are affected by a noise of solar origin produced by the Sun appearing in the antenna's field of view.

Characteristics of Patients Experiencing a Flare of Generalized Pustular Psoriasis: A Multicenter Observational Study

open access: yesVaccines, 2023
Background: Generalized pustular psoriasis (GPP) is a rare, severe inflammatory skin disease characterized by recurrent episodes of flares. Characteristics of patients experiencing a flare are hardly described in a real-life setting. The aim of the study
