Experimental study on water transfer of soil-rock mixtures under freezing action
Yantu gongcheng xuebaoThe frost-heaving failure of earth-rock dam slopes is mainly caused by the combined action of sand and gravel cushion, frost heaving of dam fills and water migration.

Method for identifying four common rock types of slopes and determining boundary range
Yantu gongcheng xuebao, 2019 Rock classification and boundary determination of rock slopes are very important for the analysis of slope stability. At present, the artificial methods are inefficient and affected by subjective factors.

Influence of Ground Motion Parameters on the Seismic Response of an Anchored Rock Slope
Advances in Civil Engineering, 2020 The seismic response of rock slopes is closely related to the dynamic characteristics of earthquakes. In this study, based on a numerical model of rock slopes with bolt support, the seismic responses of both anchored and unanchored rock slopes under ...

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Molecular Oncology, EarlyView.Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.
