Dai, Pengcheng (author), Yu, Wenwu (author), Wang, He (author), Baldi, S. (author)Actor-critic (AC) cooperative multiagent reinforcement learning (MARL) over directed graphs is studied in this article. The goal of the agents in MARL is to maximize the globally averaged return in a distributed way, i.e., each agent can only exchange information with its neighboring agents. AC methods proposed in the literature require the...journal article 2023

Yu, Ming (author), Modesti, D. (author), Pirozzoli, Sergio (author)We study turbulent flow in open channels with a free surface and rectangular cross-section, for various Reynolds numbers and duct aspect ratios. Direct numerical simulations are used to obtain accurate characterization of the secondary motions, which are found to be more intense than in closed ducts, and to scale with the bulk, rather than...journal article 2023

Wen, Weijie (author), Lyu, Rui (author), Li, Botong (author), Cao, Hong (author), Yu, Jiali (author), Li, Bin (author), Popov, M. (author)For the black start-up of DC micro-grids, three-phase charging resistors are required to limit the uncontrollable surge current. The main drawback of this start-up method is the difficulty in determining the appropriate resistance value to achieve a rapid start-up and limit the surge current with the change of grid parameters. To address this...journal article 2023

(author), Groeblacher, S. (author), Tittel, W. (author)Single quantum emitters embedded in solid-state hosts are an ideal platform for realizing quantum information processors and quantum network nodes. Among the currently investigated candidates, Er3+ ions are particularly appealing due to their 1.5 μm optical transition in the telecom band as well as their long spin coherence times.
