Abstract When ground-penetrating radar (GPR) detects red clay, the electric field induces polarization, causing corresponding characteristics in the dielectric constant and affecting GPR’s inversion of soil moisture content. This paper investigates the physical properties of Guiyang red clay, including its composition and liquid-plastic limits. Based on the electric double-layer structure on clay particle surfaces, bound water is classified into strongly and weakly bound water.

Abstract Accurate prediction of blasting vibration velocity and effective control of vibration-induced hazards remain key challenges in blasting engineering. Using monitoring data from a high-slope blasting project in the Pan Nan 2 × 660 MW low-calorific-value coal comprehensive utilization power generation project, this study develops a Bayesian dynamic updating model for peak particle velocity (PPV) prediction based on the classical Sadovsky formula.

Abstract Background: Left ventricular (LV) thrombus is a catastrophic complication during veno arterial-extracorporeal membrane oxygenation (VA-ECMO) support for cardiogenic shock, arising from a confluence of hemodynamic stasis, a prothrombotic state, and potential limitations of conventional anticoagulation monitoring.
