Influence of rhizosphere priming effects on accumulation and decomposition of soil organic carbon by MO Chaoyang, ZHANG Xinlin, YANG Jingping

“…By using a ¹³C natural abundance method, this study investigated the rhizosphere priming effects (RPE) of sorghum and maize growing in two types of soil (paddy soil and lou soil) at two stages, and the contents of light fraction organic carbon (ρ₁＜1.7 g/cm³) and heavy fraction organic carbon (ρ₂＞1.7 g/cm³) of soil were also determined. …”

Mine pressure prediction based on empirical mode decomposition linear model by Yuwei ZHU, Pengfei WANG, Huixian WANG, Qiangqiang NIU, Liang XIN

“…To ensure the safe and efficient extraction of coal mines and reduce sudden roof accidents, this study proposes a novel multivariate long-term sequence mine pressure prediction model—the Empirical Mode Decomposition Linear Model (EMD–Mixer). Unlike most fixed-length single-feature mine pressure prediction models, this model first introduces the Empirical Mode Decomposition (EMD) method to separate periodic and trend components from the mine pressure signals. …”

Numerical method and application of transient electromagnetic full-time responses of pseudo-random waveforms by Kailiang LU, Jianhua YUE, Ya’nan FAN, Danyang XI

“…For three-dimensional numerical simulations, based on the characteristics of pseudo-random waveforms, a source decoupling and Shift-and-Invert Krylov subspace technique is proposed. This method requires only one LU matrix decomposition and several dozen matrix back substitutions to solve the full-time electromagnetic field, and its accuracy is verified by comparing it with the results of the Backward Euler method. …”

Synergistic and Antagonistic Effects of Mixed-Leaf Litter Decomposition on Nutrient Cycling by Vestine Mukamparirwa, Salim M. S. Maliondo, Canisius Patrick Mugunga

“…Specifically, we expected mixtures containing nutrient-rich species to exhibit synergistic effects, resulting in faster decay rates and sustained nutrient release, while mixtures with nutrient-poor species would demonstrate antagonistic effects, slowing decomposition. We conducted a mesocosm experiment using a custom wooden setup filled with soil, and the litterbag method was used to test various leaf litter mixtures. …”
