However, the environmental characteristics of brightness variation, inter-plant occlusion, and motion-induced blurring during harvesting operations, detection algorithms face excessive parameters and high computational intensity. Accordingly, this study proposes a lightweight T.Kirilowii detection algorithm for complex mountainous environments based on YOLOv7-tiny, named KPD-YOLOv7-GD. Firstly, improve the multi-scale feature layer and reduce the complexity of the model. Secondly, a lightweight convolutional module is introduced to replace the standard convolutions in the Efficient Long-range Aggregation Network (ELAN-A) module, and the channel pruning techniques are applied to further decrease the model's complexity. Finally, the experiment significantly enhanced the efficiency of feature extraction and the detection accuracy of the model algorithm through the integration of the Dynamic Head (DyHead) module, the Content-Aware Re-Assembly of Features (CARAFE) module, and the incorporation of knowledge distillation techniques. The experimental results showed that the mean average precision of the improved network KPD-YOLOv7-GD reached 93.2%. Benchmarked against mainstream single-stage algorithms (YOLOv3-tiny, YOLOv5s, YOLOv6s, YOLOv7-tiny, and YOLOv8), KPD-YOLOv7-GD demonstrated mean average precision improvements of 4.8%, 0.6%, 3.0%, 0.6%, and 0.2% with corresponding model compression rates of 81.6%, 68.8%, 88.9%, 63.4%, and 27.4%, respectively. Compared with similar studies, KPD-YOLOv7-GD exhibits lower complexity and higher recognition speed accuracy, making it more suitable for resource-constrained T.kirilowii harvesting robots.</p>","PeriodicalId":20189,"journal":{"name":"PLoS ONE","volume":"20 4","pages":"e0320315"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic review.","authors":"Shimeng Wang, Mingyang Lu, Xiaoxiao Dong, Yifan Xu","doi":"10.1371/journal.pone.0319806","DOIUrl":"https://doi.org/10.1371/journal.pone.0319806","url":null,"abstract":"<p><strong>Background: </strong>Repetitive negative thinking (RNT) is characterized by its persistence, difficulty in control, and the tendency to focus on negative thoughts and past events. It is recognized as a key factor in the development and maintenance of mental health issues such as depression and anxiety. A growing body of research suggests that physical activity-based interventions may effectively reduce RNT. However, the extent of this effect and the mechanisms behind it remain inconsistent across studies.</p><p><strong>Methods: </strong>This systematic review synthesized evidence from 19 peer-reviewed studies retrieved from PubMed, Web of Science, and other relevant databases up to December 2024. The objective was to investigate the efficacy of physical activity-based interventions in reducing RNT, with a particular focus on the influence of intervention type, duration, frequency, and intensity.</p><p><strong>Results: </strong>The review found that physical activity interventions effectively reduce RNT, particularly when combined with psychological training. Combined interventions yielded greater reductions than physical activity alone. Moderate-to-high intensity exercise (30-60 min/session, 3-5 times/week) over an extended period was most effective, likely due to physiological, psychological, and social mechanisms. Single-session interventions showed limited effects, emphasizing the need for sustained engagement.

The findings provide empirical support for the use of combined interventions involving physical activity and psychological training as an effective strategy for managing RNT. Additionally, future research should prioritize identifying optimal intervention characteristics (e.g., type, frequency, intensity) and addressing methodological limitations, such as the inclusion of diverse participant samples and broader language coverage, to provide more comprehensive insights into effective intervention strategies.

Ubiquitin-specific peptidase 54 (USP54), an active deubiquitinase (DUB), modulates the ubiquitination of the epidermal growth factor receptor (EGFR). While the significance of USP54 in tumorigenesis is known, its specific function in cancer progression remains unclear. This study investigates the role of USP54 in gefitinib sensitivity in gefitinib-resistant non-small cell lung cancer (NSCLC) cells. Using western blotting and next-generation sequencing, we examined gene expression changes in ubiquitination pathways. USP54 deficiency and its impact on cell viability and gefitinib response were evaluated in 2D and 3D spheroid cancer models. Prolonged gefitinib exposure altered the expression of 20 deubiquitinase-regulating genes. Notably, ubiquitin C-terminal hydrolase L3, downregulated by gefitinib, was identified as a key regulator of EGFR ubiquitination in gefitinib-sensitive PC9 cells. Silencing USP54 in resistant NSCLC cells increased gefitinib-induced EGFR ubiquitination and G0/G1 cell cycle arrest, enhancing drug susceptibility in resistant spheroids. USP54 upregulation in gefitinib-treated cells was associated with reduced EGFR ubiquitination, stabilizing EGFR and promoting cell survival. These findings suggest USP54 as a critical modulator of EGFR stability and a potential therapeutic target to overcome gefitinib resistance in NSCLC.</p>","PeriodicalId":20189,"journal":{"name":"PLoS ONE","volume":"20 4","pages":"e0320668"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
