Stress State Change Monitoring Using Displacement Change Measurements [PDF]
, 2016 A method to back calculate stress state change was developed in Dynamic Control of Underground Mining Operations (DynaMine) research project. The purpose of this method is to provide real-time estimates of the stress state change caused by excavation. In

Mechanical mechanism of in situ stress ratio limit and its evolution simulation
Frontiers in Earth Science, 2022 In situ stress is a natural phenomenon. According to the Mohr–Coulomb criterion, it is found that when the ratio of principal stress (the ratio of maximum principal stress to minimum principal stress) of crustal rock mass in a certain environment exceeds

Measurements Of In Situ Stress And Mining-Induced Stress In Beiminghe Iron Mine Of China
, 2009 In order to obtain the distribution rules of in situ stress and mining-induced stress of Beiminghe Iron Mine, the stress relief method by overcoring was used to measure the in situ stress, and the MC type bore-hole stress gauge was adopted to measure the

In-situ stress analysis in the Chang 7 reservoir of northern Shannxi region
Unconventional ResourcesThe Shaanbei Chang 7 shale oil reservoir in the Ordos Basin develops vertically with multiple lithologic superimpositions. The interlayer stress of sand-mud-shale thin interbeds is different, and the stress within the small layer is variable, resulting ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
