Future 6G networks will integrate non-terrestrial communication with mobile edge computing to enable wide-area edge intelligence, providing ubiquitous communication and computation services for everyone and everything. In this paper, we introduce the intelligent cloud-edge-device architecture into low Earth orbit(LEO) satellite-supported remote Internet of Things(IoT) networks to facilitate latency-sensitive and compute-intensive IoT applications. However, the dynamic spatio-temporal characteristics inherent in LEO satellite networks, such as the high volatility of task traffic and the high mobility of space nodes, pose severe challenges. For efficient task execution, we investigate the joint optimization of cross-region task offloading and cross-domain resource allocation, and innovatively propose a spatio-temporal attention-based proximal policy optimization(STA-PPO) algorithm. Specifically, the temporal attention-based actor network analyzes the timing dependencies of task arrival and makes time-variant decisions. Simultaneously, the spatial attention-based critic network captures the spatial variations of satellite motion and evaluates the topology-related value. We verify the effectiveness of the cloud-edge-device collaboration through extensive simulations. Numerical results demonstrate that the STA-PPO algorithm outperforms benchmarks, showing the lowest system delay and the highest link throughput.

位于西南太平洋的汤加俯冲带发育有世界上最典型的“沟-弧-盆”体系,该区域不仅具有全球最快的板块俯冲速度,还发育扩张速率最快的弧后盆地——劳盆地。汤加俯冲带东北侧的萨摩亚地幔柱也与该俯冲系统间存在着强烈的相互作用,这使得该区的地幔动力过程更加复杂。虽然前人已在此进行了许多地球物理研究,但汤加俯冲带上地幔的精细三维结构,尤其是各向异性结构特征仍不清晰。为此,本文利用20~150 s周期范围内的远震基阶瑞利波的振幅和相位数据开展了方位各向异性层析成像研究,以期进一步约束汤加地区上地幔速度结构。研究结果认为:(1)萨摩亚地幔柱物质向南流入劳盆地主要发生在小于50 km的深度范围内;(2)劳盆地北部地幔楔中主要呈现东西向的地幔流动,而南部则存在南北向的地幔流动,这可能是地幔物质被动流动以适应俯冲板块不对称回卷的结果;(3)俯冲板片内主要呈现近南北向的快波方向,这可能与俯冲相关的正断层有关;(4)海沟外侧软流圈中存在平行海沟的横向地幔流动,这可能是软流圈物质受俯冲板块回卷挤压产生的。

大多数脊柱外科手术患者会经历中度至重度的急性术后疼痛,增加术后并发症风险,延长住院时间,严重影响患者术后康复。安全且有效的术后镇痛是脊柱手术患者术后早期活动和快速康复的前提条件。传统依赖阿片类药物的镇痛方式虽然有效,但是常伴随诸多不良反应。目前围术期多模式镇痛已经成为业内共识,临床上积极探索多种非阿片类静脉药物和镇痛技术在脊柱外科术后镇痛的应用价值。本文介绍脊柱外科术后急性疼痛的发生机制,总结非阿片类静脉药物、神经阻滞以及局部浸润麻醉在其术后疼痛控制上的研究进展,以期为临床工作提供参考。
