Dizhen xuebao, 2022 2008年汶川地震中江油市太白公园曲径桥上的石雕发生转动破坏现象，本文对这一转动现象进行了振动台模拟试验。模拟试验结果表明：① 在振动台三向加载1.5倍的汶川地震江油台记录的平动加速度后，模型的转动情况与实际观测的石雕转动情况比较一致；② 石雕的转动与石雕的非对称性、地震动输入角度和地震动的竖向作用有关；③ 加载竖向地震动作用后，石雕模型会发生摇摆现象，说明竖向地震动是造成模型扭转现象的重要原因，这也说明在分析相似震害现象时竖向地震动作用不可忽视。

An Analytical Solution for Block Toppling Failure of Rock Slopes during an Earthquake
Applied Sciences, 2017 Toppling failure is one of the most common failure types in the field. It always occurs in rock masses containing a group of dominant discontinuities dipping into the slope.

Effect of earthquake excitation on circular tunnels: Numerical and experimental study
Measurement + Control, 2019 This paper studies the behaviour of circular tunnel subjected to dynamic excitation. Tunnels with three different diameters were selected to perform the shake table test at three different covers. The dry sandy soil was used for testing.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Analysis of Model Embankment Dam by Shaking Table Test
Soils and Foundations, 1985 ABSTRACT Laboratory model tests have been performed on the shaking table to show the fundamental behaviour of embankment dams subjected to dynamic loads using the same dam materials. The paper shows the effects of the input motion, dam type and reservoir conditions on the response characteristics. The response data obtained are next used to identify

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
