Study on stable combustion mechanism and emission characteristics of a diesel/methanol dual-fuel injection system under constant pressure differential control

Pressure differential fluctuations can significantly disturb pilot diesel storage and ignition stability in pressure-differential-driven dual-fuel injection systems, thereby limiting the achievable methanol substitution rate (MSR). To address this issue, a constant-pressure-diffe...

Non‐Coding Transcripts From Diversified Members of IgLec Family Protect Antiviral Effectors From Viral miRNA

ABSTRACT Immune gene families frequently produce numerous non‐coding transcripts, yet their biological functions remain largely unexplored. Here, using the arthropod immunoglobulin domain‐containing lectin ( IgLec ) family as a paradigm, we provide evidence that this complexity m...

Distributed optimal scheduling of multi-microgrids considering ammonia energy storage and energy-reserve sharing

Traditional multi-microgrid typically focuses only on energy trading while overlooking reserve trading, and the high uncertainty of renewable generation makes it challenging to assess spinning reserve requirements. To this end, this paper proposes a distributed optimal method for...

Refined modeling of voltage source converter and distributed optimization for AC/DC grids with pumped storage

Accurate voltage source converter (VSC) modeling is critical for reliable optimal operation of hybrid AC/DC grids, while centralized methods suffer from poor scalability and privacy issues. This paper proposes a distributed optimization method for the coordinated optimal operatio...

AquaCrop-derived surrogate model for crop yield response to monthly irrigation deficit

Context: The Upper Yellow River Basin faces acute water competition between cascade hydropower operations and large irrigation districts. Traditional multi-objective reservoir operation leads to distorted energy-food benefit trade-offs from oversimplified linear representation of...

Adapting the temperature-fluorescence dryness index as a functional ecological indicator for tracking agroecosystem drought in China's winter wheat regions

Accurate agroecosystem drought monitoring of winter wheat is essential for ensuring food security in China. The traditional Temperature Vegetation Dryness Index (TVDI) relies on structural reflectance metrics and can be affected by delayed vegetation responses and canopy saturati...

Complementary operation rules of hydropower-photovoltaic systems to prevent power curtailment

The complementary operation of photovoltaic (PV) power with hydropower effectively promotes its integration into the power grid, but it also intensifies the competition for transmission channels, potentially leading to severe power curtailment issues. This study introduces comple...

Urban Vehicle Route Choice Modeling Based on Multi-Source Trajectory Data and Adversarial Inverse Reinforcement Learning

To address the limitations of traditional route choice models, including their dependence on manually constructed path sets, their difficulty in capturing nonlinear decision preferences, and their insufficient consideration of dynamic congestion factors, this paper proposes an ur...

Tailoring Wood Shrinkage via Solvent-Driven Interfacial Engineering for On-Demand Applications

Abstract Modulating wood cell shrinkage offers a promising yet underexplored route to advanced timber-based materials. Here, we combine chemical softening with solvent evaporation-induced assembly for programmable shrinkage control. Solvent prewetting facilitates penetration of a...

Sparse aperture ISAR imaging via nonconvex low-rank and sparsity regularization

In inverse synthetic aperture radar (ISAR) imaging, traditional range-Doppler (RD) algorithm fails to get satisfactory imaging results in sparse aperture scenarios. Compressed sensing (CS) imaging methods are commonly used for sparse aperture radar imaging. However, only sparsity...

Morphology-Invariance-Driven Transfer between sonar and optical images for underwater defect detection

Underwater defect detection (UDD) from images is essential for the safe operation and maintenance of hydraulic structures. However, UDD remains challenging because of substantial variations in appearance, limited annotated data, and degraded underwater image quality. To mitigate...

Laboratory-scale particle-level evaluation of MSWIFA-RCA granulated artificial aggregates with 2D–3D morphology-assisted screening

Recycled concrete aggregate (RCA) and municipal solid waste incineration fly ash (MSWIFA) can be co-processed into granulated artificial aggregates, but conventional batch-averaged assessments cannot adequately reveal particle-to-particle consistency, while existing single-partic...

Synthesis of Fe-Co Bimetallic Supported on Cotton Residue Biochar: Catalytic Performance and Mechanistic Investigation for CO2 Hydrogenation

Biochar carriers were prepared from cotton residue waste, and Fe-Co bimetallic catalysts with different ratios were constructed using impregnation method. Their catalytic performance in CO2 hydrogenation to hydrocarbons was investigated. The structural evolution and catalytic beh...

Integrative graph deep learning with directional decoding for robust gene regulatory network inference from single-cell transcriptomics

While gene regulatory networks (GRNs) are fundamental to understanding complex cellular mechanisms, the accurate inference from single-cell RNA-sequencing (scRNA-seq) data is hindered by the inherent noise, transcriptional dropout events, and dynamic nature of gene regulation. Cu...

Spatiotemporal evolution and driving factors of ecosystem health in the Poyang lake region under compound pressures

Abstract Revealing the mechanisms underlying ecosystem health evolution in large river-connected lakes under intensive human activities is essential for adaptive management. However, existing studies primarily focus on ecological state changes or individual driving factors, with...

Interpretable early-stage advance rate prediction for slurry shield tunnelling using TabPFN-SHAP

Accurate prediction of advance rate (AR) during early-stage shield tunnelling remains challenging because monitoring data are limited while operational parameters must adapt to changing geological conditions. This study develops an interpretable TabPFN–SHAP framework for AR predi...
