Stability evaluation of tunnels in steeply dipping layered rock mass using numerical models: a case study. [PDF]
Sci RepTunnel stability is a critical factor in complex geological conditions, particularly in rock masses with steeply dipping layers. Among widely used methods, the Convergence–Confinement Method (CCM), a prevalent two-dimensional (2D) approach, effectively ...

Blastability Classification of Fractured Rock Mass Based on Weighted Clustering Analysis
Chemical Engineering Transactions, 2017 This paper classifies the blastability of fractured rock mass based on the solid coefficient, rock impedance, unit explosive consumption and mean fracture spacing. Specifically, an evaluation model was established according to the principle of clustering

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Modification of rock mass rating system: Interbedding of strong and weak rock layers
Journal of Rock Mechanics and Geotechnical Engineering, 2017 Rock mass classification systems are the very important part for underground projects and rock mass rating (RMR) is one of the most commonly applied classification systems in numerous civil and mining projects. The type of rock mass consisting of an interbedding of strong and weak layers poses difficulties and uncertainties for determining the RMR. For
