Event-based recursive filtering for nonlinear bias-corrupted systems with amplify-and-forward relays

Systems Science & Control Engineering
In this paper, the recursive filtering issue is investigated for an array of nonlinear bias-corrupted systems with a dynamic amplify-and-forward (AF) relay under the dynamic event-triggered scheme (DETS).

Observed Hydroclimatic Trends and Their Implications Over Water‐Cycle Dynamics in Montérégie, Southern Quebec, Canada

Global Challenges, Volume 10, Issue 4, April 2026.
In this study, we quantified the changes in different hydroclimatic parameters and evaluated their impacts on the groundwater resources across Montérégie. Using the GR4J+CemaNeige model, and multi‐decadal hydroclimatic records, the study shows the watershed's variability and identifies seasons and land cover scenarios where groundwater recharge ...

A Novel Method to Determine the Grain Size and Structural Heterogeneity of Fine-Grained Sedimentary Rocks

Fractal and Fractional
Fine-grained sedimentary rocks exhibit significant textural heterogeneity, often obscured by conventional grain size analysis techniques that require sample disaggregation.

Drivers of Benthic Iron Fluxes and the Pore‐Water Iron Isotopic Signature in Surface Sediments of South Georgia Fjords, Sub‐Antarctica

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Benthic iron (Fe) fluxes from coastal sediments support phytoplankton blooms downstream of subpolar islands. We combine solid‐phase and pore‐water geochemical data, including its iron isotopic signature (δ56Feaq), to identify the main drivers of benthic Fe fluxes from sub‐Antarctic fjord and shelf sediments of South Georgia, and to evaluate ...

Prediction of Total Organic Carbon Content in Shale Based on PCA-PSO-XGBoost

Applied Sciences
Total organic carbon (TOC) content is an important parameter for evaluating the abundance of organic matter in, and the hydrocarbon production capacity, of shale. Currently, no prediction method is applicable to all geological conditions, so exploring an

Quantitative Evaluation on the Elastic Property of Oil-Bearing Mudstone/Shale from a Chinese Continental Basin [PDF]

Energy Exploration & Exploitation, 2015
This study aims at quantitatively evaluating the impact of material compositions on the elastic property (static Young's modulus) of oil-bearing mudstone and shale (MS). Six samples (two mudstone and four shale) from a Chinese continental basin (Bohai Bay basin) were investigated under different hydrostatic triaxial compression conditions. The primary
