Metasurface‐Enabled Active‐Like Passive Radar
Advanced Science, EarlyView.A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Archaeological Prospection, EarlyView.ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection
Archaeological Prospection, EarlyView.ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

English teachers' journeys since the 2020 Iteration of Black Lives Matter
British Educational Research Journal, EarlyView.Abstract The 2020 resurgence of Black Lives Matter (BLM) mobilised students in England to demand greater representation of racially minoritised voices in English curriculums—a call highlighted by stark inequity: just 1.5% of GCSE texts studied are by racially minoritised authors, despite racially minoritised students comprising 38.0% of the student ...

Dizhen xuebao, 2022 以典型的两层三跨形式地铁车站为研究对象，采用非线性动力时程反应分析方法，对软土场地的地铁车站与上部交叉桥梁模型进行数值模拟分析，给出了一种潜在的地铁车站−桥梁耦联破坏模式，分析了地铁车站与上部桥梁的地震动力相互作用。数值模拟结果表明：桥梁对车站的地震响应影响较小，车站发生破坏主要取决于地震作用及其本身的强度；地铁车站发生破坏后会引起邻近区域土层产生较大的水平和竖向变形，进而会引起邻近区域地基失效并使桥梁发生落梁破坏；地铁车站遭地震破坏后，桥梁基础带动邻近区域的土层整体向车站方向移动，加剧车站坍塌震害。

Ensemble‐based soil liquefaction assessment: Leveraging CPT data for enhanced predictions
Civil Engineering Design, Volume 7, Issue 1, Page 23-35, March 2025.Abstract This study focuses on predicting soil liquefaction, a critical phenomenon that can significantly impact the stability and safety of structures during seismic events. Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk ...
