Quantitative representation and parameter weight analysis of dimple in multi-point flexible die forming process

To investigate dimple defects in the multi-point flexible die stretch forming (MPFDSF) process, this study focuses on the quantitative characterization, prediction, and control of dimples in 2024-O aluminum alloy spherical parts. Based on ABAQUS finite element simulations, the th...

Combined Transcriptional and Metabolic Analysis of the Differences in Salt Tolerance Responses of Tillers in Different Rice Varieties

<title>Abstract</title> Background Soil salinization is a significant factor contributing to the reduction of arable land. To enhance rice productivity in saline-alkali soils, understanding the salt tolerance mechanisms of rice varieties is essential. This study focused on invest...

AhTGAs coordinate antioxidant defense and metabolic remodeling in peanut under high manganese stress

Manganese (Mn) is an essential micronutrient for plant growth, but its excess can cause oxidative stress and inhibit plant growth and development. To reveal the molecular mechanism of peanut response to manganese stress, this study systematically explored the oxidative stress res...

Effects of Dietary Alpinia officinarum Extract on Performance, Immunity, Microbiota, and Aeromonas hydrophila Resistance in Red Claw Crayfish

Plant extracts contain multiple bioactive compounds and have been extensively investigated as alternatives to antibiotic-based feed additives in aquaculture. The present study was designed to evaluate the effects of dietary supplementation with galangal (Alpinia officinarum) extr...

Study on the Measurement and Enhancement Pathways of Ecological Efficiency of Marine Fisheries in China’s Coastal Areas

Marine fisheries play a vital role in ensuring food supply and sustaining livelihoods in coastal regions of China. However, the expansion of aquaculture has led to increasing carbon emissions and mounting pressure on resources and the environment, making the improvement of ecolog...

Head–Body–Tail Segmentation of Poultry 3D Point Clouds Under Different Annotation Budgets: A Comparison of PCA-Based Rules and PointNet++-Based Methods

Head–body–tail segmentation of poultry 3D point clouds is an underexplored task in precision poultry phenotyping. This study constructs a segmentation-oriented evaluation setting to examine how supervision source and annotation budget affect the relative performance of a principa...

Effects of Dietary Curcumin Supplementation Under High-Level Fishmeal Replacement with Clostridium autoethanogenum Protein in Penaeus vannamei: Growth Performance, Immunity, Intestinal Health, and Transcriptome Responses

Clostridium autoethanogenum protein (CAP) offers a sustainable fishmeal alternative, but high inclusion may impair shrimp growth and health. This study evaluated the responses associated with dietary curcumin (CUR) supplementation in Penaeus vannamei fed a diet in which 50% of th...

La Niña’s longevity shapes Bering Sea ice fate

Abstract La Niña events vary widely in duration, from single-year to multi-year. However, their influence on Bering Sea ice concentration remains unclear. Here, we show that single-year and multi-year La Niña events produce contrasting impacts on spring Bering Sea ice concentrati...

The Effect of Low-Fishmeal Feed Including an Olive Leaf Extract (Olea europaea) Additive on Growth, Intestinal Health and Disease Resistance in Litopenaeus vannamei

This study evaluated the effects of olive leaf extract (OLE) on growth, intestinal health, and resistance against Vibrio parahaemolyticus challenge in juvenile Litopenaeus vannamei. To a basal diet containing 12% fishmeal, OLE was added at 0%, 0.10%, 0.20%, 0.40%, and 0.80%, form...

Research on the Driving Mechanism of Digital Infrastructure for Sustainable Development Resilience of Chinese Agriculture

Amid intensifying global geopolitical conflicts and increasingly frequent market fluctuations, enhancing the resilience of agricultural sustainable development has become a core issue for ensuring food security and promoting rural revitalization. Digital infrastructure offers a c...

The Impact Mechanisms and Paths of the National Big Data Comprehensive Pilot Zones on Urban Pollution Reduction and Carbon Mitigation

The National Big Data Comprehensive Pilot Zone (NBDCPZ) constitutes a landmark institutional initiative designed to advance and deploy data elements while strengthening governance capacity for environmental sustainability and low-carbon transition. Drawing on a panel dataset cove...

Temporal-Variation-Resistant Bidirectional Convolution-Transformer GAN for Remote Sensing Image Spatiotemporal Fusion

Single-source remote sensing image (RSI) cannot simultaneously meet high-spatial and high-temporal resolution requirements, failing to provide decision-makers with timely and accurate monitoring data. Spatiotemporal fusion (STF) of multi-source RSIs represents an efficient and co...
