Ground settlement and tunnel response due to twin-curved shield tunnelling in soft ground with small clear distance

Journal of Rock Mechanics and Geotechnical Engineering
Twin curved tunnels are often encountered in shield tunnelling, where significant complexities in densely exploited underground space are observed. In this study, the ground settlement and tunnel deformation due to twin-curved shield tunnelling in soft ...

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

Angewandte Chemie International Edition, EarlyView.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Influence of the Diameter Size on the Deformation and Failure Mechanism of Shield Precast Segmental Tunnel Lining under the Same Burial Depth

Buildings
With the development of large-diameter shield tunnels, how to realize effective security and stability control of shield tunnel lining has become a significant research topic.

Health Risk Prediction of Operational Subsea Tunnel Structure Based on Bayesian Network

Buildings
Recently, subsea tunnel construction has developed rapidly in China. The traffic volume of subsea metro tunnels is large. Once a safety accident occurs, economic losses and social impacts will be extremely serious.

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

The Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Lateral and Anterior Closing Wedge “9/9” Degree Osteotomy to Correct Both Tibia Vara and Excessive Tibial Slope

Arthroscopy Techniques, EarlyView.
Abstract High tibial osteotomy is a key option for patients with unicompartmental overload or instability. Although coronal correction for varus deformity is well established, excessive posterior tibial slope (PTS) is increasingly recognized as a contributor to anterior cruciate ligament graft failure.

Transtibial Anterior Cruciate Ligament Reconstruction Using a Synthetic Graft Combined With Remnant Repair: A Hybrid Technique

Arthroscopy Techniques, EarlyView.
Abstract The purpose of this technical note is to describe a hybrid arthroscopic technique that combines anterior cruciate ligament reconstruction using a synthetic graft with concomitant remnant repair. Following diagnostic arthroscopy and assessment of remnant quality, tibial and femoral tunnels are created using a transtibial approach with attention
