With the advent of the aging age of humanity, wearable medical sensors and their related smart medical networks have been widely applied. At present, there are more and more manufacturers producing wearable medical sensors. Due to the lack of adherence to unified standards, most sensor providers adopt their own standards. This system does not have plug and play medical functions at the bedside, which is a bottleneck in the development of wearable medical sensor networks.
This system is an important component of future wireless ubiquitous networks (UCWW), mainly responsible for broadcasting, discovering, and using wireless business services (Advertisement, Delivery, Association). According to the standards of Next Generation Networks (NGNs), future wireless network services can be divided into wireless access services and wireless application services. With the significant increase in the number of wireless services, wireless ubiquitous service broadcasting systems need to use an independent channel for targeted delivery.
The MobileLearning (mLearning) system consists of four parts: InfoStation, Multiple Agent System, system architecture, and content ubiquitous computing.

https://www.frontiersin.org/research-topics/64004/application-of-deep-learning-in-biomedical-image-processingDear Colleagues,
The application of deep learning in medical diagnostics is revolutionizing the field of medicine. Especially in medical imaging diagnosis, the introduction of deep learning methods has had a profound impact on the workflow from image acquisition to diagnostic reporting. These methods excel at automating tedious image analysis tasks and efficiently processing large and complex medical image datasets.
The interventions of deep learning and artificial intelligence provide new possibilities for accelerating medical diagnosis. As hardware and algorithms continue to advance, researchers are better able to understand and predict a patient's condition and link medical images to disease features. Deep learning has shown great potential in the interpretation of medical images, such as in foci segmentation, cancer detection, disease classification, and so on.
However, it is important to note that the correct application of deep learning is crucial in medical diagnosis. With deep learning, the data are analyzed and interpreted with the help of computer-expanded knowledge. The impact of these tools is huge, and the use of AI is helping many stakeholders in the field of smart healthcare. The future of applying deep learning in medical diagnostics is exciting, promising not only to improve diagnostic accuracy but also to potentially provide more precise information for personalized medicine and treatment planning. Developments in this field are pushing medical science to new heights to provide better medical care for patients.
https://www.mdpi.com/journal/bioengineering/special_issues/51FQPX7ZT0#editorsDear Colleagues,
Seen as another information and industrial wave, the Internet of things (IoT) finds wide application in multiple domains. For the provision of IoT services, the use of suitable IoT platforms is required, allowing a transparent connection with different types of IoT devices and offering (value-added) functionalities, such as application enablement, remote device control and management, telco/dew/fog/cloud connectivity and storage management, “big data” analytics and visualization, and so on, with some sort of freedom of use by and customization to users.
Following the novel horizontal design principles, which counter the former vertical/silo ones, a new horizontal type of IoT platforms has emerged that, by using the integration and interoperability principles, can simplify the existing IoT environment by eliminating duplicate solutions, enable inter-technology operation, and generate new IoT services and business opportunities. With this new approach, a service/application/network provider is enabled to deliver a complete horizontal-slice solution, applied to not just one but multiple IoT domains, meeting by the flexibility, scalability, cost-efficiency, and multi-purpose use requirements, with easy and timely adjustment of its operation to new use cases and scenarios, and with efficient management and control of the entire IoT ecosystem throughout its lifetime.
The aim of this Special Issue of Electronics is to present state-of-the-art R&D efforts in building multi-service cloud-based IoT platforms of horizontal type, applicable to different IoT domains. We invite scholars to contribute original and unique research articles, as well as review articles.
https://www.mdpi.com/journal/electronics/special_issues/LoT_electronicsS. Hao et al., "ConvNeXt-ST-AFF: A Novel Skin Disease Classification Model Based on Fusion of ConvNeXt and Swin Transformer," in IEEE Access, vol. 11, pp. 117460-117473, 2023, doi: 10.1109/ACCESS.2023.3324042.
Abstract: Automatic classification of dermatological images is an important technology that assists doctors in performing faster and more accurate classification of skin diseases. Recently, convolutional neural networks (CNNs) and Transformer networks have been employed in learning respectively the local and global features of lesion images. However, existing works mainly focus on utilizing a single neural network for feature extraction, which limits the model classification performance. In order to tackle this problem, a novel fusion model, named ConvNeXt-ST-AFF, is proposed in this paper, by combining the strengths of ConvNeXt and Swin Transformer (ConvNeXt-ST in the model’s name). In the proposed model, the pretrained ConvNeXt and Swin Transformer networks extract local and global features from images, which are then fused using Attentional Feature Fusion (AFF) submodules (AFF in the model’s name). Additionally, in order to enhance the model’s attention on the regions of skin lesions during training, an Efficient Channel Attention (ECA) module is incorporated into the ConvNeXt network. Moreover, the proposed model employs a denoising module to reduce the influence of artifacts and improve the image contrast. The results, obtained by experiments conducted on two datasets, demonstrate that the proposed ConvNeXt-ST-AFF model has higher classification ability, according to multiple evaluation metrics, compared to the original ConvNeXt and Swin Transformer, and other state-of-the-art classification models.
