Most current techniques rely solely on single-scale convolutional neural networks, overlooking the importance of extracting multi-scale information in the same convolutional layer. This may lead to overly homogeneous extracted features and lower recognition accuracy. To solve this issue, we propose the Multi-scale Parallel Convolution Neural Network (MSPCNeXt). This model extracts image features by parallelizing convolutional kernels with different scales. The MSPCNeXt-Block comprises two versions, i.e., MSPCNeXt-v1 and MSPCNeXt-v2. After optimizing the parallel branching by using large kernel decomposition and feature segmentation, MSPCNeXt-v1 and MSPCNeXt-v2 ensure a broad receptive field while lowering the model complexity. We validate the effectiveness of MSPCNeXt on the public dataset GrainSpace. Compared with the baseline model ConvNeXt, MSPCNeXt-v1 improves the mean accuracy by 2.531% and Top-1 accuracy by 2.286%, but the model size is too large. MSPCNeXt-v2 improves the mean accuracy by 2.224% and Top-1 accuracy by 1.857%. Meanwhile, the computation amount is reduced by 0.456G and the number of parameters is reduced by 5.986M. In conclusion, MSPCNeXt provides a more efficient technical tool for sampling and testing of wheat storage and related processes.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102559"},"PeriodicalIF":2.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143105380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used three initial population sizes (64, 128, and 256 individuals), each with identical maize availability (70 g), and replicated each initial population size three times. Populations were counted weekly over 12 weeks. Sigmoidal growth models, including three-phase, logistic, Gompertz, and Baranyi models, were fitted to each population. Model selection was conducted using the Akaike Information Criterion. Additionally, we assessed the influence of initial population size on population growth parameters: λ (lambda), μ (mu), and carrying capacity (K), using a one-way ANOVA. The Gompertz model best fit nearly all populations. Lambda (λ) varied significantly among initial population sizes, with the smallest populations showing the shortest lambda duration (approximately 4.247 weeks) and the largest populations exhibiting the longest duration (approximately 5.525 weeks). No significant differences were found in μ (mean μ = 0.197) or carrying capacity (K = 2.619, approximately 416 individuals) across initial population sizes. These findings underscore the role of density dependence in weevil populations, with a notable lag phase effect. Furthermore, the lack of impact of initial population size on μ indicates that small initial populations can achieve carrying capacity at the same rate as larger populations.

The proposed system incorporates paraffin wax PCM and a flat-plate solar collector connected to a drying chamber with a 20 kg capacity. This design achieves a 10 ± 0.3% increase in thermal efficiency and a 38 ± 3.1% reduction in drying time compared to traditional solar dryers. <strong>The study's novelty lies in its innovative strategy to enhance drying performance while preserving the bioactive components of kiwifruit.

Operating within a temperature range of 44–73 °C, the FPSD^PCM reduced the moisture content of kiwifruit from 93 ± 2% to 11 ± 0.5% in 5.5 h, compared to 8 h using open sun drying (OSD). Despite these advancements, limitations such as PCM selection and experimental uncertainty (32.83%) remain. Future research should focus on exploring alternative PCMs, real-time monitoring systems, and life-cycle assessments for broader agricultural applications. With an experimental uncertainty of 32.83%, the FPSD^PCM offers a cost-effective, energy-efficient, and sustainable solution for small-scale farmers.

Traditional pest counting methods, such as bounding box-based and density map-based approaches, face challenges with tiny pests (&lt;5 mm) and dense distributions.

Point-based methods improve on isolated pest detection but lack reliability in dense areas. To address these limitations, we propose the Density-Point Network (DP-Net), which integrates density maps and point regression for robust pest counting. DP-Net employs a backbone network to extract image features, which are processed by a Point-Regression Module for pest coordinates and a Density-Map Generating Module for pest distribution. A patch-select strategy combines these outputs to improve counting accuracy. Our experiments, conducted on a dataset of four stored grain pest species, demonstrate that DP-Net achieves an MAE (Mean Absolute Error) of 3.13 and an MSE (Mean Squared Error) of 5.63, outperforming traditional methods.

Sorghum storage management practices of 120 farmers were surveyed, the occurrence of multiple mycotoxins in samples from their stored sorghum was determined, and potential relationships between the traditional storage management practices and mycotoxin contamination were analyzed.
