Seismo-ripples

Earthquake prediction has long been considered one of the greatest challenges in the global scientific community due to the complex and uncertain nature of seismogenic processes, along with the prevailing consensus that earthquakes are inherently unpredictable. Here, we present a...

Hydration sequence controls polymer-induced water repellency and hydraulic response in illite-rich clay

Although geomaterial hydrophobisation is well established, the role of hydration sequence in polymer-induced water repellency of illite-rich clay remains insufficiently constrained. A butyl-acetate-assisted polydimethylsiloxane (PDMS) formulation was applied to a multi-mineral il...

Hydrothermal carbonization process waters: Linking composition with recovery, recirculation, and treatment routes

Hydrothermal carbonization process waters (HTC PWs) contain feedstock-derived carbon, nutrients, dissolved ions, and potentially recoverable organics, but also inhibitory and poorly biodegradable fractions. This review links feedstock composition and HTC conditions to PW composit...

Intelligent prediction under rockburst class imbalance: A coupled model fusing KMeans-SMOTE and CatBoost

Solving the problem of data class balance is the key premise to ensure the performance of rockburst intelligent prediction model. This paper adopted an oversampling method (KMeans‑SMOTE) based on K‑means clustering and Synthetic Minority Oversampling Technique (SMOTE). Firstly, t...
