This study investigates the potential application of Zn5Al1.5Mg1.5Ti active solder in ultrasonic soldering of AlO ceramics and Cu substrates. The research explores the microstructural characteristics, phase composition, and mechanical properties of the solder and the resulting joints. Particular attention is given to the formation mechanisms of the solder-substrate bond and the role of ultrasound activation in enhancing wettability and bond strength. The study aimed to provide a deeper understanding of active soldering processes and their suitability for high-temperature applications. The findings contribute to advancing lead-free soldering technologies for electronic and structural applications.

The development of anode materials for lithium-ion batteries must meet the demands for high safety, high energy density, and fast-charging performance. TiNbO is notable for its high theoretical specific capacity, low structural strain, and exceptional fast-charging capability, attributed to its Wadsley-Roth crystal structure. However, its inherently poor conductivity has hindered its practical application.

Background: Despite the Coronary Artery Reporting and Data System (CAD-RADS) providing a standardized approach, radiologists continue to favor free-text reports. This preference creates significant challenges for data extraction and analysis in longitudinal studies, potentially limiting large-scale research and quality assessment initiatives.
Objective: To evaluate the ability of the generative pre-trained transformer (GPT)-4o model to convert real-world coronary computed tomography angiography (CCTA) free-text reports into structured data and automatically identify CAD-RADS categories and P categories.

Background: Circumcision is a widely practiced procedure with cultural and medical significance. However, certain penile abnormalities-such as hypospadias or webbed penis-may contraindicate the procedure and require specialized care. In low-resource settings, limited access to pediatric urologists often leads to missed or delayed diagnoses.

Background: Over the past decade, the proportion of the world's population aged ≥65 years has grown exponentially, presenting significant challenges, such as social isolation and loneliness among this population. Assistive technologies have shown potential in enhancing the quality of life for older adults by improving their physical, cognitive, and communication abilities. Research has shown that smart televisions are user-friendly and commonly used among older adults.
