Natural swarms arranged from cells to herds are usually decentralized but display intriguing collective intelligence in coordinating individuals across large scales to efficiently achieve their common goals. Learning from nature may provide new strategies for controlling collective dynamics of synthetic swarms to accomplish specific functions. Here, we present a bioinspired computational framework that steers distributed active swarms to collectively capture and merge targets via reinforcement learning. We exploit collective milling structures of natural herds to cage the targets, and adopt a switching control policy inspired by sperms' chiral dynamics to optimize the trajectories of individuals, through which the active swarms can selforganize to enclose single or multiple distant targets in a dynamical, adaptive and scalable manner. There exists a critical swarm size, beyond which the excessive competition between agents would generate large mechanical forces, leading to capture instability but enabling the transition from short-distance to long-distance merging capture of multiple targets. This work provides physical insights into distributed active swarms and could offer a multilevel, decentralized strategy toward controlling swarm robotics in wide applications such as bio-medical devices, machine immunity, and target clearance.

目的探讨标准化急救护理流程对急性缺血性脑卒中溶栓治疗时间窗的影响。方法选取我院收治的60例急性缺血性脑卒中患者为研究对象,2015年6月至2016年12月收治的30例患者作为对照组,2017年1月至2018年6月收治的30例患者作为观察组。对照组患者实施传统急救护理,观察组患者实施标准化急救护理流程,比较两组患者的静脉开通时间、CT完成时间、到院至静脉溶栓时间(DNT)、住院时间;比较两组患者治疗前后脑卒中量表评分(NIHSS)和日常生活活动能力量表评分(Barthel);比较两组患者不良反应发生情况。结果观察组患者住院时间、CT完成时间、静脉开通时间、DNT均短于对照组,差异有统计学意义(P 0. 05),两组治疗前后比较差异均有统计学意义(P 0. 05)。结论在急性缺血性脑卒中患者的急救中应用标准化急救护理流程,可有效缩短其静脉开通时间,CT完成时间,DNT和住院时间,降低NIHSS评分和提升Barthel评分,降低两组患者不良反应的发生情况,值得临床推广应用。

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.
