Spatial Prediction and Performance Comparison of Soil Organic Carbon in High-Latitude Forest Soils Based on Multiple Feature Selection Methods and Machine Learning Models

Soil organic carbon (SOC) in permafrost regions is a critical component of terrestrial carbon reservoirs, and spatially explicit multi-depth mapping is essential for identifying subsurface carbon emission hotspots and supporting carbon neutrality accounting. The Kamalan River Bas...

An Active Sonar Signal Detection Algorithm Based on Weighted Neighbourhood Relative Entropy in the Underwater Acoustic Noise Environment

This paper presents a target detection method for active sonar based on weighted neighbourhood relative entropy (WNRE), using tools from information geometry. The method segments the matched-filter output of each echo by a sliding window, estimates the probability density of ever...

Enhanced Figure‐of‐Merit Energy Harvesting in [001]‐Oriented PMN‐PZT Ceramics Via Synergistic Multi‐Scale Engineering

ABSTRACT Developing piezoelectric materials with a high figure‐of‐merit (FOM = d 33 × g 33 /tan δ ) is crucial for advanced energy‐harvesting technologies. Here, a high FOM is achieved in [001]‐oriented Pb(Mg 1/3 Nb 2/3 )O 3 ‐PbZrO 3 ‐PbTiO 3 (PMN‐PZT) textured ceramics by synerg...

Teacher Caring Behaviour and Junior High School Students' Learning Engagement in Physical Education: The Mediating Roles of Psychological Capital and Learning Motivation

ABSTRACT Background Physical activity has been shown to benefit students' academic achievement and engagement, yet the mechanisms remain unknown. In the present study, we aimed to examine the relationship between teacher caring behaviour and learning engagement among junior high...

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...

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...

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...
