Initially, the neural network undergoes training with calculated data (leg tilt angles and angular velocities) sourced from the OpenSim database, followed by further refinement with experimental data obtained from a subject walking on a treadmill, wherein leg tilt angles and angular velocities are measured.

The purpose of this study was to conduct a systematic review to update the scientific evidence on injury incidence in competitive divers to offer insights into the prevalent injury patterns and help develop injury prevention strategies. This involved analyzing injury data collected from the Injury Surveillance Programme (ISP) across various levels of competition events and assessing case reports involving a wide spectrum of diving injuries. Four online bibliographical databases were consulted: Google Scholar, PubMed, Scops, and Web of Science from their inception until December 6, 2023.819 studies were initially identified, and 15 studies were finally included in this review. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISM) guidelines and PRISMA in Exercise, Rehabilitation, Sport Medicine, and Sport Science (PERSiST) were followed. Two independent reviewers evaluated the methodological quality of the studies. The majority of diving injuries are concentrated on the upper body/trunk, including the shoulder, spine, hand/wrist, head/face, and neck, with overuse injury being a main contribution. Regarding diving incidence, the actual injury rate in competitive athletes could be even higher than currently reported, primarily due to limitations in implementing injury surveillance protocol for diving athletes. The latest injury data for diving in big competition events is absent, and there is a strong expectation for more new injury surveillance data to be published in the future. Additionally, the specific injury pattern, prevention strategy, and rehabilitation training plan for diving injury are severely deficient in the current literature.</p></div>","PeriodicalId":33783,"journal":{"name":"Medicine in Novel Technology and Devices","volume":"23 ","pages":"Article 100316"},"PeriodicalIF":0.0,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590093524000328/pdfft?md5=cfb7c59ecde62e072a45f18455e67ce6&pid=1-s2.0-S2590093524000328-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141480547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed a multifunctional baicalin-coordinated borate ions/bacterial cellulose (Bai-B/BC) composite hydrogel at a low gelation concentration to promote chronic wound healing. On the one hand, the mechanical property of the self-assembled Bai-B hydrogel network was improved by the BC hydrogel network in the composite hydrogel; on the other hand, the self-assembled Bai-B hydrogel network gave the composite hydrogel the ability to self-heal and continuously release baicalin and boron ions. Importantly, baicalin and borate ions in Bai-B/BC composite hydrogel dressing played a synergistic pharmacological role in wound healing. The <em>in vitro</em> results showed that the Bai-B/BC hydrogel had excellent biocompatibility, antibacterial activity and anti-inflammatory effects in comparison with the control group and other hydrogel groups.

Triangular-shaped cuts in the brace allow for plastic material flexibility, ensuring movement and comfort. Significant is the absence of a traction strap, which traditionally reduces the support surface and could create pressure points leading to patient discomfort or treatment rejection. The design facilitates a wide contact surface with the hand, optimal load distribution, and the capacity to adjust dual traction straps independently, adapting to the natural wrist movement. This single-piece base orthosis offers a stable, cost-effective, and patient-friendly alternative to conventional splints.

The integration of high-density surface electromyography (HD-sEMG) and deep neural networks (DNNs) has significantly improved the robustness and accuracy of HGR systems. These methods are typically effective for a fixed set of trained gestures. However, the need for new gesture classes over time poses a challenge. Introducing new classes to DNNs can lead to a substantial decrease in accuracy for previously learned tasks, a phenomenon known as “catastrophic forgetting,” especially when the training data for earlier tasks is not retained and retrained. This issue is exacerbated in embedded devices with limited storage, which struggle to store the large-scale data of HD-sEMG. Class-incremental learning (CIL) is an effective method to reduce catastrophic forgetting. However, existing CIL methods for HGR rarely focus on reducing memory load. To address this, we propose a memory-friendly CIL method for HGR using HD-sEMG. Our approach includes a lightweight convolutional neural network, named SeparaNet, for feature representation learning, coupled with a nearest-mean-of-exemplars classifier for classification. We introduce a priority exemplar selection algorithm inspired by the herding effect to maintain a manageable set of exemplars during training. Furthermore, a task-equal-weight exemplar sampling strategy is proposed to effectively reduce memory load while preserving high recognition performance. Experimental results on two datasets demonstrate that our method significantly reduces the number of retained exemplars to only a quarter of that required by other CIL methods, accounting for less than 5 % of the total samples, while still achieving comparable average accuracy.</p></div>","PeriodicalId":33783,"journal":{"name":"Medicine in Novel Technology and Devices","volume":"22 ","pages":"Article 100308"},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590093524000249/pdfft?md5=3029ec8dac29af1192a16ef30701452b&pid=1-s2.0-S2590093524000249-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141089954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
