RT-ProtoNet: radiative-transfer-guided few-shot prototype networks for cross-region bathymetry in optically clear reef environments

Satellite-derived bathymetry faces two coupled obstacles: labels are scarce, and models transfer poorly across regions. We propose RT-ProtoNet, a radiative-transfer-guided few-shot prototype network, which takes patches from three penetrating Sentinel-2 bands and treats ICESat-2...

A semi-empirical prediction model for scour depth around riprap-protected monopiles under steady currents

Local scour around monopiles remains a major concern for offshore foundations, and riprap protection is widely used to mitigate scour. However, residual deformation and scour within riprap protection layers may still occur, and their prediction remains less established than conve...

Multi-omics insights into linalool-mediated modulation of microbial metabolism during cigar tobacco solid-state fermentation

Mold contamination in solid-state fermentation (SSF) severely compromises product stability and safety, leading to spoilage and off-flavor formation. Although synthetic preservatives are used, they often induce ecological instability and residual risks, prompting a shift toward n...

High-temperature mechanical properties of basalt fiber-reinforced concrete after salt spray erosion

To investigate the durability performance of basalt fiber-reinforced concrete (BFRC) subjected to the coupled effects of salt spray erosion and fire-induced high temperatures, this study systematically conducted combined exposure tests with salt spray durations (0, 30, 90, and 18...

Coupled Prediction of Grout Diffusion and Ground-Surface Heave During Fracture Grouting in Layered Soil

To establish a quantitative link between grout propagation and ground-surface heave in grouting-based settlement remediation, this study proposes a semi-analytical framework based on energy balance and volume conservation. The equivalent diffusion radius is first solved from an e...

Uncertainty quantification-driven shear wave velocity prediction using a spatiotemporal Bayesian neural network

Abstract Shear wave velocity (Vs) is a key parameter used for seismic data processing and evaluating oil and gas reservoirs. Conventional logging and machine learning methods are hampered by the provision of fixed Vs predictions, which limits their capacity to effectively quantif...

Fine Assessment of Water Abundance and Water Inflow Potential in Coal-Bearing Strata Based on Water Storage Space Microelements

Abstract Mine water inflow is one of the primary hazards threatening the safety of coal-mining production. Groundwater in coal-bearing strata serves as the direct water-filling source for coal mining, and its water abundance significantly impacts the intensity of the mine water i...

Experimental study on the characteristics of methanotrophs in degrading coal seam methane using a RL-TW80 formulation

Deep coal seams exhibit strong hydrophobicity and significant gas–liquid-solid interfacial mass transfer resistance, which severely limit methane degradation by methanotrophs . To address this, an interfacial chemical modification method combining anionic and nonionic surfactants...

Bidirectional coupling mechanism and multiphysics damage evolution of UHMWPE composite laminates under blast-fragment synergistic loading

This study investigates the dynamic response and multi-field damage evolution of ultra-high molecular weight polyethylene (UHMWPE) composite laminates subjected to blast-fragment-coupled loading. The aim is to elucidate the ambiguous failure mechanisms and address the challenging...

A source-to-sea decision-support framework for wet-weather wastewater load management: evidence from Jiaozhou Bay

Coastal concentration compliance can overlook increased wastewater throughput during wet weather. We developed a source-to-sea decision-support framework using 2019–2022 wastewater, river, and marine observations from Jiaozhou Bay, China. The analysis combined source-record audit...

Hydro-Mechanical Degradation and Progressive Failure of Sandstone–CGFB Composite Structures Under Cyclic Water Immersion: Implications for Water-Induced Instability Risk in Backfilled Goafs

Sandstone and cemented coal gangue-fly ash backfill (CGFB) form composite load-bearing structures in goafs, where repeated water ingress and drainage may weaken stability. This study investigated sandstone–CGFB composite specimens subjected to 0, 3, 6, and 10 water immersion–dryi...

Disassembly sequence planning of end-of-life smartphones based on an improved PSO-GA algorithm

Efficient and damage-free disassembly of components is one of the effective methods for achieving resource reutilization and sustainable development. For disassembly sequence planning of end-of-life (EoL) smartphone parts, intelligent algorithms with rapid convergence and dynamic...

Effects of synergistic ultrasonic–NaClO treatment on coal microstructure at different liquid saturations

Efficient coalbed methane (CBM) extraction is important for safe coal mining and for utilizing this gas as a relatively clean energy resource. Low–permeability coal is generally characterized by a compact matrix and poorly connected pore–fracture networks, which restrict methane...

Investigation of glacier mass balance based on multi-source observation in the Karakoram over the past 25 years

The “Karakoram Anomaly” — the atypical stability of glaciers in a warming climate—has introduced considerable uncertainty into projections of regional water resources. However, the resilience of this anomaly under sustained climate forcing remains poorly quantified. In this study...

Multiobjective Optimization of Cross-Flow Membrane Channel Geometry via Integrated CFD Modeling and RSM-Desirability Function Analysis
