Artificial Intelligence for Mineral Exploration Imagery: A Systematic Mapping Review of Data, Tasks, and Methods

Artificial intelligence (AI) is increasingly applied to image-based and image-formatted geoscientific evidence across mineral exploration, from regional and surface surveys to drilling/core analysis and laboratory characterization. However, the literature remains distributed acro...

Tectono-magmatic–volatile coupling in postcollisional giant porphyry Cu formation: Evidence from slab tearing and mantle inputs at Qulong, Tibet

The origin of postcollisional porphyry copper deposits (PCDs) within thickened crust remains debated, particularly regarding the coupling between tectono-magmatic–volatile evolution and ore formation. At Qulong, Tibet, new geochemical and isotopic data across four Miocene intrusi...

Outer Surface Functionalized Graphene Oxide Nanofluidic Platform for Selective Detection of Insect Pheromones

Abstract Invasive insects inflict severe ecological and economic damage, creating an urgent need for rapid and early detection strategies. Here, we present a biomimetic strategy that replicates the molecular recognition principles of insect olfaction. As a proof of concept, our p...

RASM-Net: A Reliability-Aware Structural and Multiscale Modeling Network for RGB-T Object Detection in Complex Environments

Visible–thermal (RGB-T) object detection improves robustness in complex environments, such as low-light and densely occluded forest scenes, by integrating complementary information from the two modalities. It has therefore become a key technology for all-weather perception. Howev...

Molecular Insights into the Effect of Nanoscale Surface Roughness on CO2 Hydrate Nucleation: Implications for Carbon Sequestration

Abstract Hydrate-based CO2 sequestration is a promising carbon storage technology, but its practical application is hindered by slow formation kinetics. Understanding the nucleation mechanism at a molecular level is crucial for optimizing this process. Herein, systematic microsec...

Navigating the synergy between environmental efficiency and productivity in China's land operation scale expansion

Balancing productivity growth with emissions reduction is a central challenge for sustainable agriculture. Using over 390,000 household-year observations from 1993 to 2020, this study examines how land operation scale affects greenhouse gas emission intensity (GEI) and unit produ...

Experimental Study on the Identification of Impact-Induced Secondary Damage Inside Concrete Based on Multi-Domain Vibration Signal Indicators

A large number of in-service concrete components in infrastructure are prone to internal secondary damage, which seriously threatens the long-term safety of structures. To effectively identify internal secondary damage in concrete structures and reveal the influence of cracks on...

Geothermal gas geochemistry in a source-pathway-reservoir framework: review, applications, and limitations

Geothermal gases serve as sensitive recorders of heat sources, fluid pathways, and reservoir conditions in geothermal systems. However, their original signals are often obscured by multi-endmember mixing, gas-water partitioning, phase separation, and sampling biases, limiting the...

Pressure‐Induced Single‐Molecule Deformation Enables 208‐Fold Photoluminescence‐Intensity Enhancement in Zero‐Dimensional Copper Iodide Hybrids

ABSTRACT Hybrid metal halides exhibit diverse excited‐state behaviors, yet the molecular‐level origin of pressure‐induced emission enhancement (PIEE) remains elusive. Here, we develop a rational molecular design strategy to isolate pressure‐induced single‐molecule deformation as...

Machine learning reveals divergent drivers and migrating thresholds of cropland degradation in Southern and Northern China

Under the dual pressures of rapid urbanization and climate change, cropland systems in China are facing escalating degradation risks, posing a critical threat to national food security. However, the compound driving mechanisms and nonlinear threshold effects underlying cropland d...

Experimental study on chemical plugging of weakly consolidated sandstone by geothermal tailwater recharge based on artificial cores

Characterization of Rock Fabric and Its Influence on Water Occurrence in Tight Gas Reservoirs

Abstract After hydraulic fracturing, the flowback rates of some tight gas reservoirs are less than 50%, which seriously affects tight gas production. Regarding the fracturing fluid retention mechanism in tight gas reservoirs, it is still unclear. This research focused on the rock...

The effect of hybrid models integration sequence: taking Fushun area as an example

Landslide susceptibility zoning (LSZ) is a crucial step in reducing landslide related losses, and its accuracy remains a long-standing research focus. Hybrid models are widely used, but little is known about coupling sequences. Here, we show that the accuracy of hybrid models can...

A global gridded dataset of significant wave height via fusion of multi-mission altimetry and numerical hindcast

Satellite altimeters provide long-term, high-accuracy observations of significant wave height (SWH) over the global ocean. However, their sparse spatial and temporal sampling introduces undersampling errors in wave climate analyses. Direct gridding of multi-mission altimeter data...

Endogenous instability: modeling behavioral, structural, and environmental drivers in the coal-power supply chain

The stability of the coal-power supply chain is vital to energy security but often undermined by overlooked behavioral and structural forces. This paper develops a discrete-time agent-based simulation model incorporating three sector-specific features: the structural feature (cap...

A Cover-based Enhanced Direct Search Approach for Contact Detection of Convex Polyhedral Blocks and Its Application with 3D DDA

In implicit numerical simulation of block systems, the establishment of complete inequality constraints and the accurate enforcement of contact constraints are fundamental issues. However, the conventional direct search (DS) method is usually based on a local type identification...
