Liu, Guixian (author), Peng, Zhan (author), Jing, Guoqing (author), Wang, Shilei (author), Li, Yaonan (author), Guo, Y. (author)Ground penetrating radar (GPR) is a popular technology for inspecting railway ballast layer, mainly on the ballast fouling level. However, different GPR antennas with different frequencies are suitable for different inspection emphasis and diverse railway lines (weather and sub-structure). In addition, the full-scale track model (with...journal article 2022

(author), Obersteiner, Michael (author), Guo, Zhaoxia (author), Bryan, Brett A. (author)Progress to date toward the Sustainable Development Goals (SDGs) has fallen short of expectations and is unlikely to fully meet 2030 targets. Past assessments have mostly focused on short- and medium-term evaluations, thus limiting the ability to explore the longer-term effects of systemic interactions with time lags and delay. Here we undertake...journal article 2022

Wang, Shilei (author), Liu, Guixian (author), Jing, Guoqing (author), Feng, Qiankuan (author), Liu, Hengbai (author), Guo, Y. (author)In the past 20 years, many studies have been performed on ballast layer inspection and condition evaluation with ground penetrating radar (GPR). GPR is a non-destructive means that can reflect the ballast layer condition (fouling, moisture) by analysing the received signal variation. Even though GPR detection/inspection for ballast layers has...review 2022

Liu, Gang (author), Du, Zhao (author), Xiao, Tian (author), Guo, Junfei (author), Lu, Liu (author), Yang, Xiaohu (author), Hooman, K. (author)Solar energy, as a kind of renewable energy, offers a large reserve to be harvested at a reasonably low cost for engineering applications. To decouple the temporal and spatial relevance of the continuous energy supply of solar energy, latent heat thermal energy storage can deal with this problem at different temperatures. Aiming to improve...journal article 2022

(author)Nanomagnets are widely used to store information in non-volatile spintronic devices. Spin waves can transfer information with low-power consumption as their propagations are independent of charge transport. However, to dynamically couple two distant nanomagnets via spin waves remains a major challenge for magnonics. Here we experimentally...journal article 2020
