recommendations! Published in 2023 at "European Journal of Physics"

DOI: 10.1088/1361-6404/acd287

Abstract: The initial movement of a hanging string is revisited through an integral transformation, the analysis of the integral solution allows to obtain some exact solutions for the string profile and to understand the physical meaning… read more here.

DOI: 10.1088/1475-7516/2025/03/015

Abstract: Motivated by the hint for time-dependent dynamical dark energy from an analysis of the DESI Baryon Accoustic Oscillation (BAO) data together with information from the Cosmic Microwave Background (CMB) and Supernovae (SN), we relax the… read more here.

DOI: 10.1088/1674-4527/21/1/21

Abstract: The early lunar mantle overturn, associated with the sinking of the dense ilmenite-bearing cumulate (IBC) crystallized at the shallow lunar mantle, provides satisfactory explanations for the origination of high-Ti basalt, the abnormally strong magnetic field… read more here.

DOI: 10.1134/s0965542518090099

Abstract: A mixed problem for a homogeneous wave equation with fixed ends, a summable potential, and a nonzero initial velocity is studied. Using the resolvent approach and developing the Krylov method for accelerating the convergence of… read more here.
