Asymmetries in random motions of neutral hydrogen gas in spiral galaxies
(EDP Sciences, 2023-10-01)Context. The velocity dispersion ellipsoid of gas in galactic discs is usually assumed to be isotropic. Under this approximation, no projection effect occurs in the random motions of gas, as traced by the line-of-sight ... -
Beyond AdS2/dCFT1: insertions in two Wilson loops
(Springer Science and Business Media Deutschland GmbH, 2023-10)We consider two-point correlators of local operator insertions in a system of two Wilson-Maldacena loops in N = 4 supersymmetric Yang-Mills theory on both sides of the AdS/CFT correspondence. On the holographic side the ... -
A Multi-Objective Approach for Optimizing the Layout of Additional Boreholes in Mineral Exploration
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-10)Accurate subsurface exploration requires an optimal network of boreholes. This paper proposes a multi-objective approach to optimize the layout of additional exploratory boreholes. In order to illustrate this approach, ... -
Microwave-Assisted Semisynthesis and Leishmanicidal Activity of Some Phenolic Constituents from Lichens
