Is flux rope a necessary condition for the progenitor of coronal mass ejections?

, 2015
A magnetic flux rope structure is believed to exist in most coronal mass ejections (CMEs). However, it has been long debated whether the flux rope exists before eruption or is formed during eruption via magnetic reconnection.

Evolution of Magnetic Helicity in Solar Cycle 24

, 2019
We propose a novel approach to reconstruct the surface magnetic helicity density on the Sun or sun-like stars. The magnetic vector potential is determined via decomposition of vector magnetic field measurements into toroidal and poloidal components.

Evolution of active and polar photospheric magnetic fields during the rise of Cycle 24 compared to previous cycles

, 2012
The evolution of the photospheric magnetic field during the declining phase and minimum of Cycle 23 and the recent rise of Cycle 24 are compared with the behavior during previous cycles.

Simulating the Solar Corona with Multiple Solar Photospheric Magnetic Maps during the 2024 April 8 Total Solar Eclipse

The Astrophysical Journal
The 2024 April 8 total solar eclipse provides a unique opportunity to study the solar corona. This work presents our simulations of the solar corona at the time of the eclipse based on magnetohydrodynamic modeling performed with the Alfvén Wave Solar ...

Comparative Assessment of Long-Term Outcomes of Allogeneic Hematopoietic Stem Cell Transplantation from Unrelated Donors Registered in the Russian and International Databases for Hematologic Diseases

Клиническая онкогематология
BACKGROUND. In recent years, the number of allogeneic hematopoietic stem cell transplantations (allo-HSCT) has continued to rise due to the ongoing improvement of transplantation technologies and rapid growth of bone marrow donor registries.
