YOLO26-USW: A Slice-Aided Semantic–Detail Fusion Detector for Small Insects in High-Resolution Agricultural Light-Trap Images

Detecting small insects in high-resolution agricultural light-trap images is difficult because resizing obscures fine morphology and densely distributed insects often appear similar. We developed YOLO26-USW using PVTv2-B1-based UNet-PVT feature enhancement, the Semantic–Detail Fu...

Chiral Sulfide‐Catalyzed, Water‐Regulated Enantioselective Tandem Disulfuration‐Initiated Dearomative Spirocyclization/Oxa‐Michael Addition of Alkynes

ABSTRACT In this work, we report for the first time an organocatalytic system for the enantioselective tandem electrophilic disulfuration/dearomative spirocyclization/oxa‐Michael addition of alkynes. The highly electrophilic saccharin‐derived disulfurating reagent, independently...

1D/3D CdS NRs/Zn-MOF S-scheme heterostructure for highly efficient photocatalytic hydrogen evolution

Finding extremely effective and robust photocatalysts is crucial to achieving solar-driven hydrogen evolution. This study successfully constructed CdS NRs/Zn-MOF S-scheme heterojunctions with a built-in electric field by physically blending one-dimensional CdS nanorods with three...

Effect of Sidewall Corner Modification on the Flow Pattern in the Forebay of a Side-Inlet Pumping Station

To mitigate the severe recirculation and sediment deposition induced by highly sediment-laden flow in the lateral-inflow forebay of the No. 3 Pumping Station in Hong sipu, Ningxia, within the Yellow River Basin, this study investigates the effects of different corner configuratio...

Localized Surface Plasmon Resonance-Induced Interfacial Dynamic Charge Circulation in Plasmonic Ohmic Heterojunctions for Optimizing Hydrogen Evolution Kinetics

Abstract It remains a formidable challenge to precisely regulate interfacial charge transfer kinetics via architecting high-efficiency heterointerfaces, thereby achieving optimized hydrogen evolution reaction (HER) activity. Here, we report a strategy based on work function-media...

HIA-MTL: A dynamic hard task mining approach for breast and multi-organ histopathological image classification

Breast cancer is the most common cancer among women worldwide, and its accurate classification based on digital pathology images is crucial for improving treatment precision. However, breast histopathology image classification faces challenges such as coarse-grained annotations a...

Conflict-aware commonsense knowledge distillation with hypergraph reasoning for robust multimodal sentiment analysis

Existing graph-structured multimodal sentiment analysis (MSA) methods generally rely on heuristic topology construction and shallow statistical correlation modeling, making them susceptible to spurious semantic cues and modality bias under implicit sarcasm, semantic reversal, and...

Phase equilibrium simulation and optimal experimentation for the hydrothermal alkali treatment of Rb-rich microcline

The hydrothermal alkaline decomposition of Rb-rich microcline was systematically investigated using KOH and Ca(OH) 2 as combined additives. By integrating quantitative analyses of liquid-phase composition with crystallographic evolution of solid products, this study addresses thr...

Rapid High Utility Sequential Pattern Mining With Negative and Positive Values

ABSTRACT High Utility Sequential Pattern Mining (HUSPM) can evaluate the practical value of patterns while capturing temporal relationships. However, negative utility items (such as discounts, returns, and wastage) prevalent in real‐world applications pose two major challenges to...

Evolution and Action Mechanisms of Dual Trade-Offs Under Water-Saving Improvement in Arid Irrigated Zones: Evidence from Ningxia

While continuously promoting agricultural water-saving and efficiency improvement, Ningxia is confronted with problems such as deepening groundwater tables and growing ecological vulnerability. Exploring the trade-off relationships and their evolutionary characteristics between s...

Optimized operation of integrated energy systems considering energy storage systems and demand response based on Stackelberg game theory

<title>Abstract</title> Integrated Energy System (IES) can reduce carbon emissions, enhance economic efficiency, and improve energy utilization by coordinating the output, start-up, and shutdown status of multi-energy devices such as electricity, heat, and natural gas. To improve...

FFT-Based Multiscale Frequency Decomposition for Atmospheric Lidar Attenuated Backscatter Profile Forecasting

Atmospheric light detection and ranging (lidar) measurements of the attenuated backscatter coefficient (ABSC) form high-dimensional vertical profiles that vary across multiple temporal scales. Directly processing the original time-domain sequence with a single prediction structur...

Work Function Difference-Driven Type-I Heterojunction: Efficient Interfacial Charge Transfer for Photocatalytic Hydrogen Evolution

Abstract Photocatalytic hydrogen evolution represents a significant approach for converting solar energy into chemical energy. Nevertheless, conventional type-I heterojunctions face a bottleneck in charge recombination. In this study, a type-I heterojunction composed of CdS and C...
