Response simulation and primary vertex reconstruction in the SPD NICA straw tracker
Вестник Самарского университета: Естественнонаучная серияIn this work we investigate the temporal structure of the events in the spin physics detector (SPD) straw tracker at the JINR NICA. Using the Geant4 toolkit we simulate the response of the straw layers sensitive elements in the triggerfree regime of SPD.

Development of High-Efficiency Multisensor Detection System for Gamma Emission Tomography in Spent Nuclear Fuel Inspection [PDF]
Journal of Radiation Protection and ResearchBackground Gamma emission tomography (GET) is one of the most reliable methods for detection of partial-defects within spent nuclear fuel (SNF). In our previous study, we developed and proposed the scintillation crystal-based GET instrument named Yonsei ...

Chorus Wave‐Induced Ionospheric Variability
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.
