To explain the recent three-year La Ni?a event from 2020 to 2022, which has caused catastrophic weather events worldwide, Fasullo et al.(2023) demonstrated that the increase in biomass aerosol resulting from the 2019-20 Australian wildfire season could have triggered this multi-year La Ni?a. Here, we present compelling evidence from paleo-proxies,utilizing a substantial sample size of 26 volcanic eruptions in the Southern Hemisphere(SH), to support the hypothesis that ocean cooling in the SH can lead to a multi-year La Ni?a event. This research highlights the importance of focusing on the Southern Ocean, as current climate models struggle to accurately simulate the Pacific response driven by the Southern Ocean.

With the growing demand for wireless communication networks, achieving efficient and equitable channel access schemes has become paramount. In this paper, we delve into the realm of distributed channel access in homogeneous wireless networks, focusing on both fairness and efficiency. We introduce a media access control protocol, named Fair and Efficient Multiple Access (FEMA), by leveraging decomposed Multi-Agent Deep Deterministic Policy Gradient (MADDPG). FEMA decouples the dual objectives into self-oriented efficiency reward and team-oriented fairness reward. Correspondingly, local critic networks and global critic networks target self-oriented reward and team-oriented reward, respectively. Extensive simulations demonstrate FEMA’s superiority over conventional MAC protocols and other multiple access techniques based on deep reinforcement learning, showcasing its ability to simultaneously enhance fairness and efficiency.

We report a multi-functional flexible intelligent glove that integrates artificial tactile and olfactory sensor array. It is able to assist wearers and humanoid robots in tasks such as gesture recognition and combustion odor detection. Our proposed convolutional neural network algorithm can fuse multidimensional sensing information, distinguish typical gestures, and achieve an accuracy of 97.2 % in recognizing four types of combustibles. It provides opportunities for rapid decisionmaking in the rescue fields of gas analysis and target recognition. Keywords: Multi-dimensional fusion, intelligent glove, sensor array
Recent advancements in machine learning and deep learning have brought algorithmic fairness into sharp focus, illuminating concerns over discriminatory decision making that negatively impacts certain individuals or gr...
