DOI: 10.1002/2017gl073031
Abstract: Using gross averages of the azimuthal component of flow in Saturn's magnetosheath, we find that flows in the pre-noon sector reach a maximum value of roughly half that of the post-noon side. Corotational magnetodisc plasma… read more here.

DOI: 10.1007/s12346-016-0187-y
Abstract: In this paper we introduce non-local-in-time complexified Lagrangians characterized by an expanded complex backward–forward derivative operator which generalize the classical complex derivative operator. We developed the Euler–Lagrange equations and solved them for some special case.… read more here.

DOI: 10.1017/jpr.2023.102
Abstract: Abstract We prove that the local time of random walks conditioned to stay positive converges to the corresponding local time of three-dimensional Bessel processes by proper scaling. Our proof is based on Tanaka’s pathwise construction… read more here.

DOI: 10.1029/2024ea003880
Abstract: ICON observations were used to investigate local time (LT) and latitudinal variations of thermospheric meridional winds in the middle‐high thermosphere (160–300 km) during quiet times in 2020 June and December. At middle‐low latitudes (10°S–40°N), meridional… read more here.
