In recent years,terahertz (THz) technology has made significant progress in numerous applications;however,the highly sensitive,room-temperature THz detectors are still rare,which is one of the bottlenecks in THz *** this paper,we proposed a room-temperature electrometry method for THz detection by laser spectroscopy of cesium(^(133)Cs) Rydberg atoms,and conducted a comprehensive investigation of the five-level system involving electromagnetically induced transparency (EIT),electromagnetically induced absorption (EIA),and Autler–Townes (AT) splitting in^(133)Cs *** solving the Lindblad master equation,we found that the influence of the THz electric field,probe laser,dressing laser,and Rydberg laser on the ground state atomic population as well as the coherence between the ground state and the Rydberg state,plays a crucial role in the transformation and amplitude of the EIT and EIA *** and the atomic vapor cell’s dimensions affect the number of^(133)Cs atoms involved in the detection,and ultimately determine the *** predicted the proposed quantum coherence THz detection method has a remarkable sensitivity of as low as 10^(-9)V m^(-1)Hz^(-1/2).This research offers a valuable theoretical basis for implementing and optimizing quantum coherence effects based on Rydberg atoms for THz wave detection with high sensitivity and room-temperature operation.

2023年,台湾地区各方政治势力围绕2024年两项选举展开激烈争夺。民进党当局执政状况迭出,党内丑闻弊案频发,派系恶斗,失能失德问题突出,台湾地区社会形成了“下架民进党”的主流民意。民进党一方面通过炒作两岸议题制造紧张局势、对国... 详细信息

2023年,台湾地区各方政治势力围绕2024年两项选举展开激烈争夺。民进党当局执政状况迭出,党内丑闻弊案频发,派系恶斗,失能失德问题突出,台湾地区社会形成了“下架民进党”的主流民意。民进党一方面通过炒作两岸议题制造紧张局势、对国民党等在野势力进行“抹红”并炒作所谓内地“介选”议题展开基本盘动员;另一方面则加紧与美国勾连以提振选情,并对非绿阵营进行分化瓦解,加速“蓝白合”破局,最终坐收渔人之利,赢得台湾地区领导人选举的胜利。但民进党执政失能失德的问题也愈发难以掩饰,虽然“蓝消绿涨”的趋势已由量变进入质变阶段,民进党基本盘优势相对稳固,但青年支持者和浅绿支持者的流失又成为其难以回避的危机。相较之下,民众党的政治实力明显增强,已成为推动台湾地区政党政治生态重构的重要力量。台湾地区政局的上述变化意味着岛内政治结构进入裂解与重塑进程的加速期,其对政治生态的影响正逐步显现。

针对深度Q网络(deep Q-learning network,DQN)算法在解决多交叉口交通信号配时方案由于外部环境变化和内部参数波动导致效果不佳的问题,提出了基于柔性“行动器-评判器”(soft actor-critic,SAC)的交叉口交通信号控制方法,并设计了相应的系统采样策略和回报函数.与原采样策略相比,新采样策略将相邻智能体的策略信息加入到系统状态中,使当前智能体能够得到更多的交叉口交通分布和合作策略信息.与原回报函数相比,新回报函数中引入空间折扣因子,缩小了相邻智能体的观察和回报值,使当前智能体更加关注和改善当前交通状况.随后在此基础上分别应用DQN和SAC算法设计交通信号控制方法.Webster配时法是利用相位流量数据开发的一种基于周期的固定相位长度交通信号方法,与DQN和SAC算法相比,其优化目标是降低交叉口延迟时间,不考虑交叉口排队长度.在城市交通模拟软件(simulation of urban mobility,SUMO)中构建一个时变交通流交通网络,并在其中分别对基于DQN、SAC和Webster配时法的信号配时控制方法进行仿真测试.仿真结果表明:基于SAC算法的交通信号控制方法与基于DQN算法和Webster配时法的交通信号控制方法相比,能够显著减少交叉口排队长度和平均延迟时间,具体来说,车辆平均排队长度分别减少了17.8%和28.2%,平均延迟分别减少了26.8%和36.3%,说明所提出的方法具有更好的控制效果.
