Study on ratcheting of beams under the combination of gravity and seismic load
Mechanical Engineering Journal, 2019 Ratcheting is one common phenomenon under excessive earthquakes. This study focuses on clarifying the ratcheting mechanism of beams subjected to the combination of gravity and seismic loadings. The sinusoidal excitations or their combinations represented

Rectangular reinforced concrete tank loaded by seismic load [PDF]
MATEC Web of Conferences, 2020 Tanks have currently been used for storage of different substances and products. Most often they serve as reservoirs for drinking water, for wastewater treatment and storage of various technical liquids. Rectangular tanks are less common, still there are many benefits of their using, e.g.

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 ...

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 ...
