International Journal of Urban and Regional Research, EarlyView.Abstract From desert ski resorts to subtropical Winter Games, there is a global proliferation of ‘mission‐impossible’ mega‐projects. The prevailing frameworks of city branding and urban entrepreneurism fail to explain the political logics behind these seemingly irrational projects.

考虑电-气-碳综合交易的跨国电网分散式电力调度—以规划的东北亚跨国电网为例 [PDF]
全球能源互联网, 2019 为了实现跨国电网的有序发展与协调运行，跨国层面的电力交易、天然气交易和碳交易的有机结合十分关键。为此，以电力系统为核心，考虑天然气交易与碳交易的相关耦合因素，建立了跨国电-气-碳综合交易模型。在上述综合交易的框架下，建立了跨国电网的动态电力调度模型，以实现全局效益的最大化。进一步地，为了保护各个国家的工业信息隐私，提出了分散式的跨国电力调度算法，将全局优化问题转化为各个国家的子问题迭代求解，得到满足给定精度的全局最优解。最后，对东北亚跨国电网仿真算例进行测试，分析讨论在不同电-气 ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Co‐Teaching in a Virtual Intensive Study Language Programme: Insights From Team Ethnography
International Journal of Applied Linguistics, EarlyView.ABSTRACT As virtual study abroad becomes an increasingly important form of international education, little is known about how transnational teaching is organised and sustained across institutions. Using activity theory as an analytical framework and team ethnography as methodology, this study examines a virtual intensive study (VIS) programme delivered

全球能源互联网, 2018 刚果河是世界上水力资源最为丰富的大河之一，其中超过40%集中在刚果（金）下刚果省的英加地区。自上世纪五十年代大英加工程设想提出以来，英加水电的开发和外送一直受到全世界的关注。然而，受限于建设资金和消纳市场等问题，目前开发率尚不到百分之三，具备巨大的发展潜力。从消纳空间和比较优势两方面分析了英加水电的潜在市场，并结合电源开发进度提出了输电方案。分析表明，大英加工程作为非洲重要的清洁能源基地，其外送电力在西部非洲、南部非洲和北部非洲具有较强的竞争力。加快大英加水电开发和外送对推进非洲能源互联网建设 ...

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Overcoming the strength–ductility trade‐off in face‐centered cubic (FCC) multi‐principal element alloys (MPEAs), particularly at cryogenic temperatures, remains a significant challenge. Here, a laser powder bed fusion (LPBF)–enabled direct aging strategy is employed to modify the precipitation behavior in a Ni53Fe20Cr23Nb4 (at%) alloy.
