全球能源互联网, 2019 伴随风电大规模接入电网，其不确定性为电网的决策调度带来了新的挑战，风电消纳评估由此成为研究热点之一。以不确定集合表征风电不确定性，建立了两阶段鲁棒优化模型，以解决电-热综合能源系统的风电消纳能力评估问题。主问题基于风险指标优化风电可消纳域，并在算法处理中引入分段线性化处理非线性的风险表达式；子问题引入风电可接纳判据寻求风电不确定集合中的极端场景。最后着重比较电-热综合能源系统与电力系统的风电消纳能力差异。

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Zhejiang Daxue xuebao. Lixue ban, 1999 用INDO方法研究了氮杂与硼杂碳笼CnX(n=59,69;X=N+,B-)的电子结构和光谱,表明CnX与C60,C70相比将发生结构畸变,氮杂碳笼比硼杂碳笼稳定,C70中靠近极附近的两种C原子易被杂原子置换.本文在对电子跃迁进行理论指认的同时,讨论了光谱红移的原因.

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 ...

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, EarlyView.Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.
