Rock bursts usually happen during the hours or days after tunnel excavation, even in an unsupported opening where no collapses occur. To investigate the mechanism of those delayed failures in brittle rock tunnels, this paper showcases the performed scale-model test based upon the Jinping II headrace...

There has been a growing interest in the role of oligodendrocytes (OLs) and the myelin sheaths they form around axons in cognitive function. Historically, OLs were primarily considered to be involved in axonal insulation and signal transmission within the central nervous system (CNS). However, an in...
