The unprecedented rate of metro construction has led to a highly complex network of metro lines.Tunnels are being overlapped to an ever-increasing degree.This paper investigates the deformation response of double-track overlapped tunnels in Tianjin, China using finite element analysis (FEA) and field monitoring, considering the attributes of differ
In the realm of railroad transportation, the switch sliding baseplate constitutes one apunisw2 of the most crucial components within railroad crossings.Wear defects occurring on the switch sliding baseplate can give rise to issues such as delayed switch operation, inflexible switching, or even complete failure, thereby escalating the risk of train
Streptococcus pyogenes is an important human pathogen and surface structures allow it to adhere to, colonize and invade the human host.Proteins containing leucine rich repeats (LRR) have been identified in mammals, viruses, archaea and several bacterial species.The LRRs are often involved in protein-protein interaction, are typically 20-30 amino ac
