Unveiling the new round of trade-in policies in China: an “objectives-tools-targets” analysis framework

Trade-in policies play an important role in advancing sustainable consumption in China, but their sustained effectiveness still faces obstacles. This study constructs a trade-in policy mix analysis framework, which integrates the three dimensions of policy objectives, tools and t...

Observations of groundwater-surface water exchange effects on emerging pollutants in a subtropical catchment

The occurrence of emerging pollutants (EPs) in aquatic environments is a major threat to natural ecosystems and human health, but the connections between EPs in surface water and groundwater have been largely unexplored. Here, a total of 38 EPs, including antibiotics, per- and po...

Mélange diapir origin for Neo-Tethyan ridge-subduction magmatism

The mélange diapir model invokes physical mixing of partially melted slab components with mantle wedge peridotite, enabling material transfer from the subducted slab to the overlying mantle wedge. However, identifying distinctive igneous rock suites generated through this process...

Water Vapor Adsorption Behavior Evolution of MarineKerogen across Maturity from Carbonization to Graphitization Stages:New Insights Based on Thermodynamic and Kinetic Characterization

Abstract The water adsorption behavior of marine overmature kerogen is a theoretical foundation for the shale gas exploration and development and CO2 geological sequestration. However, this issue remains poorly understood, especially regarding graphitization effects. This study i...

Dynamic properties of rock bolted by high performance NPR anchor bolts with different preloads

NPR (Negative Poisson's Ratio) bolts are advanced support materials engineered for stabilizing deep underground excavations, distinguished by their exceptional deformability and energy absorption capacity. This work examines how bolt preload affects the dynamic response of bolted...

Machine learning–driven structural health monitoring of a high-rise building on thick sediments via seismic ambient noise

Seismic ambient noise enables non-invasive monitoring of high-rise buildings, but existing indicators trade floor-level localization for operational simplicity. Resonance-frequency changes track whole-building stiffness but poorly localize structural variations, whereas inter-flo...

Prediction andControlling Factors of Macrolithotypesin Deep Coal Reservoirs

Abstract Deep coalbed methane (CBM) in the Ordos Basin is a critical resource for China’s unconventional gas supply. Accurate identification of coal macrolithotypes is essential for reservoir characterization and guiding efficient exploration and development. However, the deep co...

Nanoscale Formation,Structure, and Stability of Phosphate-IronColloids at Anoxic-Oxic Interfaces

Abstract The mobility of phosphorus (P) at anoxic–oxic interfaces is largely controlled by the formation of phosphate-iron (Fe) colloids, yet the nanoscale mechanisms underlying their formation, structure, and stability remain poorly described. Here, we systematically investigate...

IceRWKV: A Novel River Ice Segmentation Network Based on Context Clustering RWKV

River ice semantic segmentation is a crucial task that provides essential information for hydrological monitoring and infrastructure protection in cold regions. Previous works mainly focus on global long-range dependency modeling or local feature extraction, while the balance bet...

OVT-Domain Azimuthal Traveltime-Constrained AVO Inversion Method

Azimuthal traveltime analysis provides comparatively stable fracture-orientation estimates but limited information on fracture-related elastic changes, whereas amplitude variation with offset (AVO) inversion is sensitive to residual azimuthal moveout. We propose a sequential offs...

Are corporate cash holdings sensitive to neighborhood carbon emissions?

Abstract As carbon transition and regulatory risks escalate, understanding the impact of local carbon emissions on corporate financial strategies is essential, particularly in shaping cash holding policies to manage environmental liabilities. This study investigates the impact of...

Effects of Blood Flow Restriction Training on Explosive Power in Athletes: A Systematic Review With Meta-Analysis

Abstract Dong, Y, Shi, B, and Li, C. Effects of blood flow restriction training on explosive power in athletes: A systematic review with meta-analysis. J Strength Cond Res 40(9): 1147–1159, 2026—The primary objective of this systematic review and meta-analysis was to quantify the...

Assessing Differentiated Land Supply Performance Under China’s Major Function-Oriented Zone Strategy: A Scale–Structure–Efficiency Perspective

China launched the major function-oriented zone planning (MFZP) strategy in 2010 to address regional imbalances and resource–environment pressures through differentiated regulation. Using county-level data from 2010 to 2020, this study develops a “scale–structure–efficiency” fram...

Insights into antibiotic sulfadiazine effects on denitrification process of Paracoccus denitrificans during continuous aerobic-anaerobic shift

Nitrogen-driven eutrophication progressively depleting oxygen frequently occurs in aquatic ecosystems, where the co-occurrence of extra pollutants such as antibiotics substantially impacts microbial nitrate removal processes. However, the denitrification response to oxygen level...

Exploration and Development of Unconventional Oil and Gas Resources: Latest Advances and Prospects: 3rd Edition

Against the backdrop of the ongoing transition of the global energy system toward cleaner, lower-carbon, and more diversified development, unconventional oil and gas resources remain essential for ensuring energy security and supporting energy-structure transformation [...]

Color Depth Gradient in Color-Change Fluorite from Brazil: A Multi-Spectroscopic Study on the Coloration Mechanism

Au Single‐Atom Interlayer Bridge Promotes Cross‐Layer Charge Transport and Intrinsic Catalytic Dual‐Sites Activation for Efficient CO 2 Photoreduction

ABSTRACT Layered photocatalysts are attractive for artificial photosynthesis, but their performance is often limited by inefficient charge transport across interlayer gaps and sluggish surface reaction kinetics. Herein, we propose a single‐atom interlayer bridge strategy by intro...

Tripolyphosphate-MediatedInterfacial Electronic ReconfigurationBoosts •OH Production and Redirects Mineral EvolutionDuring FeS Oxygenation

Abstract Oxygenation of mackinawite (FeS) at redox interfaces constitutes a key biogeochemical process that generates hydroxyl radicals (•OH) and facilitates contaminant attenuation. However, the influence of common inorganic ligands such as tripolyphosphate (TPP) on interfacial...
