Microchannel plates (MCPs) are the key components for low-level light night vision systems. Electron brushing is a crucial processing for MCPs manufacturing. In this paper, an imprinted carbon nanotubes (CNTs) field emission cathode is fabricated and tested. And the electron brushing experiment based on this cathode is carried out. The result shows that the imprinted CNTs cathode has some advantages and can be used in electron brushing. This research lays the foundation for massive, low cost and highly efficient electron brushing applications in the future. © 2024 institute of Physics Publishing. All rights reserved.

Corrosion poses a significant challenge in industries due to material degradation and high maintenance costs, making effective inhibitors essential. Recent studies suggest expired pharmaceuticals as alternative corrosion inhibitors, but identifying the most efficient compounds can be time-consuming. This study applies machine learning models, particularly Gradient Boosting Regressor (GBR), to predict corrosion inhibition efficiency (CIE). The developed model is integrated into a web-based application, enabling real-time, accurate CIE predictions. Results show GBR as the more precise model for predicting CIE, with low error rates. The streamlit-based web application offers a user-friendly platform, facilitating quick identification of suitable inhibitors. It is flexible, supporting analysis beyond corrosion inhibitors, and significantly enhances the efficiency of the evaluation process. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.

Corrugated silicon nitride masks (SiNMs) of 2000 ppi are developed to reduce the shadowing effect in direct patterning of high-resolution, RGB side-by-side OLED microdisplays. Periodic corrugations in the free-standing silicon nitride membrane elevate the through-apertures and reduce the gap between the mask and the substrate. © 2023, John Wiley and Sons Inc.

To address the lack of accuracy and speed of aircraft detection in complex background images, the YOLOv5 model is improved in this paper to meet the growing demand for aircraft detection. Firstly, Mosaic-9 data enhancement is performed on the dataset, and MobileNet V3 Small is used to replace ResNet feature extraction network to enrich small target samples and improve feature extraction speed. Secondly, over-fitting is prevented by Label Smoothing, and channel pruning is used to reduce the complexity and redundancy of the neural network. Finally, TensorRT is used to optimize the underlying hardware resources to improve the detection speed. The experiments use Military Aircraft Detection Dataset for model training and validation on NVIDIA Tesla P100 16GB GPU. The results show that our improvements maintain the accuracy of the model while effectively increasing the training speed and detection speed of the model. © 2022 IEEE.

Person re-identification(ReID) aims to match and track people in a surveillance system with non-overlapping camera views. It is a key challenge for person ReID to learn robust and discriminative person representations. However, in the real world, similar person appearance, different image angles and changing person attributes make the task very difficult. To tackle this problem, we propose the attribute guided graph convolutional networks(AG-GCN) to design a model with stronger generalization. Specifically, an attribute transfer module is introduced into the framework to revise person attributes to obtain diverse person feature expression. In addition, we apply graph convolutional networks to combine attributes with body parts as a more fine-grained representation of the person. The experiment results conducted on Market 1501 and DukeMTMCReID datasets show that our method outperforms state-of-the-art attribute-based methods on a single dataset and generalizes better on other datasets. © 2022 IEEE.

Motion capture (MoCap) suffers from inevitable noises. The raw markers can be mislabeled, occluded, or contain positional noise, which must be refined before being used for production. However, the clean-up of MoCap data is a costly and repetitive work requiring manual intervention of trained experts. To address this problem, this paper proposes a novel end-to-end Transformer-based framework called U-Solver for obtaining joint transformations directly from raw markers (called solving). Through the hierarchical framework composed of decoupled spatio-temporal (DeST) Transformer and the introduction of motion-aware network (MAN) in the temporal self-attention mechanism, U-Solver effectively learns the motion dynamics from both spatial and temporal dimensions. The raw markers can be automatically cleaned and solved through the U-Solver. The experimental results demonstrate that U-Solver outperforms previous state-of-the-art methods in terms of robustness, efficiency, and precision. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Metabolic and electrical responses to potassium deficiency stress in strawberries

引用

Engineering in Agriculture, Environment and Food 2023年第2期16卷 53-61页

作者： Kuroda, Kiko Imaizumi, Teppei Yasuda, Masaharu Niikawa, Takeshi Nakano, Kohei Katsuno, Nakako Nishizu, Takahisa Graduate School of Natural Science and Technology Gifu University Japan Faculty of Applied Biological Sciences Gifu University Japan Gifu University Institute for Advanced Study Japan Gifu Prefectural Agricultural Technology Center Japan United Graduate School of Agricultural Science Gifu University Japan

The effects of potassium concentration on the metabolomic and electrical responses of strawberry fruits were investigated. The potassium concentration of fruit harvested in January, March, and April were determined. Quality differences were observed in April, with lower potassium levels resulting in lower Brix values and acidity. Intracellular resistance and cell membrane capacity, as determined by impedance analysis, were correlated with acidity and sugar content, respectively. In addition, metabolomic analysis by gas chromatography-tandem mass spectrometry (GC-MS / MS) indicated that stress markers, such as putrescine, were detected before quality differences appeared. While impedance analysis is useful for evaluating the tissue condition of strawberries, metabolomic analysis can be used to predict quality changes. © 2023 Elsevier B.V.. All rights reserved.
