One of the most common shoulder injuries is the rotator cuff tear (RCT). The risk of RCTs increases with age, with a prevalence of 9.7% in those under 20 years old and up to 62% in individuals aged 80 years and older. In this article, we present first a microwave digital twin prototype (MDTP) for RCT detection, based on machine learning (ML) and advanced numerical modeling of the system. We generate a generalizable dataset of scattering parameters through flexible numerical modeling in order to bypass real-world data collection challenges. This involves solving the linear system as a result of finite element discretization of the forward problem with use of the domain decomposition method to accelerate the computations. We use a support vector machine (SVM) to differentiate between injured and healthy shoulder models. This approach is more efficient in terms of required memory resources and computing time compared with traditional imaging methods.

Background: Solid lung lesions are common in clinical practice, and percutaneous thermal ablation has been shown to be an effective treatment for these lesions. While computed tomography (CT)-guided microwave ablation (MWA) therapy is frequently used for adult solid lesions, it is rarely considered for pediatric cases.

Background: Pulmonary nodule ablation is an effective method for treating pulmonary nodules. This study is based on the traditional CT-guided percutaneous microwave ablation (MWA) of pulmonary nodules. By comparing laser guidance technology with freehand method, this study aims to explore the safety and efficacy and patients' pain scores of these two approaches.

Human rights investigations demand reliable data sources to substantiate alleged events, and satellite imagery offers diverse options crucial for evidential support. This paper delineates how Earth Observation (EO) imagery can be tailored to align with the requirements outlined by the Office of the United Nations High Commissioner for Human Rights (OHCHR) indicators, facilitating stakeholders in optimising their studies with applicable technological applications. To streamline EO technology, the paper categorises it into six primary payloads capable of observing such events: multispectral visible.

Confront with this challenge, it is essential to propose a strategy to design a single-layer metasurface with multi-spectrum responses in microwave and infrared ranges. In this work, we proposed a method of designing meta-atoms, which is capable of achieving functional electromagnetic response at microwave and infrared individually.
