Waveform-preserving source-independent wave-equation-based local-scale traveltime inversion: Application to the SEG Chevron 2014 blind test dataset

Summary Full Waveform Inversion (FWI) leverages the amplitude and phase of full wavefield seismic data to obtain high-resolution subsurface structures by minimizing an objective function. However, FWI encounters severe cycle-skipping issues when the seismic data lack low-frequenc...

Characterizing Long-Term Urban Impervious Surface Dynamics and Landscape Pattern Evolution Through an Integrated Area–Density Perspective

Impervious surface expansion is a defining manifestation of urbanization, but changes in total area alone cannot reveal how transitions in development density reshape landscape structure. Adopting an integrated area–density perspective, this study examined impervious surface expa...

TFCRNet: Dual-Discriminator SAR-to-Optical Translation and Region-Gated Cross-Attention Fusion for Thick-Cloud Removal

Thick-cloud contamination severely limits the usability of optical remote sensing imagery because cloud-covered regions may suffer from complete loss of surface information. Synthetic aperture radar (SAR) imagery provides complementary structural cues due to its cloud-penetrating...

Effect of scale-dependent permeability on the propagation of seismic waves in fluid saturated rocks

Abstract Wave-induced local fluid flow at different scales, which contributes most to the wave velocity and attenuation, is determined not only by the compressibility of rock but also by its permeability properties. To investigate the potential relationship between permeability a...

Multiscale Analysis of Depositional Architecture and Diagenetic Evolution in the Cretaceous Shoreface‐to‐Shelf Sandstones, Lower Indus Basin, Pakistan

ABSTRACT Understanding reservoir heterogeneity in siliciclastic systems requires integrated analysis across multiple scales. This study investigates the Early Cretaceous Lower Goru Formation in the Lower Indus Basin using a multiscale integrated approach that combines seismic str...

Black carbon in urban atmospheres: source apportionment, mixing states, and implications for climate and respiratory health

Black carbon (BC) is a major urban pollutant affecting climate and health. This review examines studies published between 2018 and 2026 on BC sources, mixing state, and impacts. Traffic emissions dominate developed cities, while biomass and residential combustion are major source...

Inversion-based reconstruction of equivalent single-source waveforms for predicting blast-induced vibrations in adjacent tunnels

The conventional Anderson model provides a physically interpretable approach to waveform-based blast vibration prediction but requires a measured single-hole response, which is often unavailable in tunnel construction. This study proposes an inversion-based Anderson framework tha...

Does the supply of eco-assets match the demand for eco-products spatially? A case study of the Yangtze River Delta urban agglomeration

The value realization of eco-assets through eco-product consumption requires both a sufficient ecological supply base and enabling demand-side conditions. Yet assessments in economically developed regions often focus on supply alone. A supply-only assessment can hide the spatial...

Dynamic Responses of Groundwater Flow and Salt Transport to Storm Surge Inundation in Unconfined Coastal Aquifers

Abstract Storm surges severely salinize coastal aquifers, yet post‐storm subsurface hydrodynamics remain poorly understood. We investigated surge inundation in unconfined tidal aquifers, revealing that subsurface flow recovers much faster than salinity distributions. Immediately...

Influence of Water-to-Powder Ratio on the Frost Resistance of Tuff Powder-Modified Self-Compacting Concrete

Self-compacting concrete (SCC) shows considerable potential for infrastructure applications on the Qinghai–Tibet Plateau, which is characterized by a hypoxic environment. However, the quantitative effects of the volumetric water-to-powder ratio (VW/VP) on the freeze–thaw durabili...

Multi-objective wake steering optimization for monopile offshore wind turbines considering pile-soil interaction

Wake effects reduce downstream wind turbine power output, significantly impacting offshore wind farm performance. While wake steering strategies can mitigate these adverse effects, they also influence the dynamic response and fatigue damage of both upstream and downstream turbine...

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions i...

Does Smart City Policy Widen the Urban–Rural Income Gap? Evidence from the Yangtze River Delta Using a Double Machine Learning Approach

The urban–rural income gap remains a major obstacle to achieving common prosperity and poses a key challenge for developing countries undergoing modernization. Smart city initiatives may reshape wealth creation and income distribution while promoting urban development. Using pane...

A surrogate modeling approach for rapid moving-load prediction of steel box girder bridges within a unified COMSOL framework

Different software platforms may influence the surrogate model’s comparison and evaluation results. To overcome this challenge, this paper develops a unified surrogate modeling framework to predict the structural responses of a steel box girder bridge under moving-load analysis,...

Bayesian SPDE–INLA modelling of rainfall in South Africa: a structured thermodynamic spatiotemporal interaction approach

Abstract Climate variability in South Africa is increasingly characterised by rising temperatures and changing rainfall patterns, posing challenges for climate risk assessment and adaptation planning. This study develops a hierarchical Bayesian spatiotemporal framework to model m...

Analytical and Laboratory Investigation of Groundwater Pumping in Strip Island Aquifers With Single‐Sided Land Reclamation

Abstract Land reclamation has been widely implemented on oceanic islands to alleviate land scarcity. Previous studies of groundwater pumping in reclaimed island aquifers have primarily considered symmetric reclamation and fixed well placement. Here, we extend this framework to an...

Widespread spring discharge drives major water–salt–heat fluxes in salt marshes

Abstract The occurrence, spatial distribution, and flux significance of submarine groundwater discharge (SGD) through preferential pathways in low‐permeability salt marshes remain poorly understood. Using thermal infrared imaging and in situ measurements, we mapped 983 saline spr...

Simulation of Discharge Evolution in the Main Streams of Large Rivers Using a Deep Learning Model: A Case Study of the Yellow River, China

Abstract Simulating river discharge evolution is fundamental to water resources management in large river basins. Nevertheless, human activities such as intensive water abstraction, reservoir operation, and other anthropogenic interventions have rendered the patterns of river dis...

Has hydrological alteration driven ecosystem service risks in large floodplain lakes? A novel framework for spatiotemporal assessment and hydrological thresholds identification

Study region Poyang Lake, China’s largest freshwater lake, is a critical ecological hub. Study focus Hydrological alteration strongly affects floodplain ecosystem services (ES), yet their spatiotemporal risks and hydrological controls remain poorly understood. We developed an int...

Can the mitigation of water constraints promote regional entrepreneurial activity? Evidence from China

Traditional entrepreneurial choice models typically consider only entrepreneurial talent and capital inputs, neglecting natural resource endowments. The debate over whether the scarcity of natural resources affects regional entrepreneurial activity remains inconclusive. In countr...
