AC2C: Adaptively Controlled Two-Hop Communication for Multi-Agent Reinforcement Learning [PDF]
arXiv, 2023 Learning communication strategies in cooperative multi-agent reinforcement learning (MARL) has recently attracted intensive attention. Early studies typically assumed a fully-connected communication topology among agents, which induces high communication costs and may not be feasible.

Gender &History, Volume 34, Issue 3, Page 827-837, October 2022., 2022 Abstract This article argues that one way to foreground and privilege women's perspectives on the Cold War is by re‐interpreting their historical experiences of food and drink. The article develops this argument by analysing one letter, from an unknown woman to the BBC, in the context of nuclear health concerns in early Cold War Britain.

Mode Hopping for Anti-Jamming in Radio Vortex Wireless Communications [PDF]
IEEE Transactions on Vehicular Technology, 2018 Frequency hopping (FH) has been widely used as a powerful technique for antijamming in wireless communications. However, as the wireless spectrum is becoming more and more crowded, it is very difficult to achieve efficient antijamming results with FH-based schemes.
