Abstract: Radio dynamic zones (RDZs) are geographical areas within which dedicated spectrum resources are monitored and controlled to enable the development and testing of new spectrum technologies.

Abstract: The electrothermal model is a widely used approach for calculating the temperature of silicon carbide metal-oxide-semiconductor field-effect transistors (SiC MOSFETs) in converters. However, ...

理解建筑几何形状的影响，例如立面突出的元素（如肋条），对于准确预测城市风场至关重要。虽然使用大涡模拟（LES）的计算流体动力学（CFD）能够在具有立面突出元素的城市峡谷中提供可靠的风场预测，但这些方法耗时且资源密集，无法用于快速评估。

该研究聚焦于欧洲云杉属（*Abies* spp.）过去20,000年的人口动态重建，旨在通过整合古气候数据和空间统计模型，揭示森林树种对气候变化的响应机制，并为未来预测提供科学依据。研究团队采用创新的两阶段回归克里金法（regression kriging），结合气候变量与物种 ...
