Party Affiliation of the US President and Path Dependence in the Bilateral Relationship With Mexico at Five Critical Junctures

open access: yesWorld Affairs, Volume 188, Issue 2, Summer 2025.
ABSTRACT The historical bilateral relationship between Mexico and the United States has been marked by punctuated equilibrium, including extended periods of stability disrupted by sudden endogenous change. These critical junctures forced decisions and realignments, creating a path dependency of action from the north and adaptation from the south of the

特高压交流输电线路电磁场分布特性与纯声衰减规律研究

open access: yesGaoya dianqi, 2017
特高压交流输电线路低频噪声对走廊沿线居民生活影响不容忽视,尤其是交流纯声沿线路横向衰减慢且传播距离远,对临近居民生活影响往往更为严重。为了研究纯声的分布规律及影响程度,文中按照电磁环境参数测量方法分别测量了特高压交流同塔双回输电线路直线塔和耐张塔下方50、100、200 Hz的3种纯声频率噪声及直线塔电磁场分布值,获得了相应噪声的频谱直方图、瀑布图和电磁场随距离变化曲线,分析了各频率噪声随距离的变化规律,结果表明:不同频率低频噪声随远离线路中心的衰减规律不同,50 Hz频率噪声从线路中心至边相导线外20

考虑用户偏好和阻塞管理的多微网分布式电能交易区块链模型

open access: yesGaoya dianqi
在多微网分布式电能交易市场中,用户偏好不完善、匹配机制不稳定会造成交易者违约,同时,潜在的线路阻塞问题也会影响配电网安全和交易效率。为此,提出考虑用户偏好和阻塞管理的多微网分布式电能交易区块链模型。首先,利用各微网主体申报价格、用户信誉值、历史合作基础、最大可供电能等信息构建用户合作偏好指标,并对购售电双方进行评估,形成合作偏好排序结果。其次,提出基于Gale-Shapley算法的双边匹配机制,使得参与主体能够在交易市场的双向选择中获得稳定匹配结果。再次,提出基于深度优先搜索(depth-first ...
