Construction and Experimental Validation of Embedded Potential Functions for Ta-Re Alloys.

Ta/Re layered composite material is a high-temperature material composed of the refractory metal tantalum (Ta) as the matrix and high-melting-point, high-strength rhenium (Re) as the reinforcement layer. It holds significant potential for application in aerospace engine nozzles. Developing the Ta/Re potential function is crucial for understanding the diffusion behavior at the Ta/Re interface and elucidating the high-temperature strengthening and toughening mechanism of Ta/Re layered composites.

Research on the Influence of Liquid Metal Embrittlement Cracks on the Strength and Fatigue Life of Spot-Welded Joints of Galvanized Q&P980 Steel.

Galvanized high-strength steel has emerged as a key focus in automotive lightweighting research. During resistance spot welding of galvanized steel, the phenomenon of liquid metal embrittlement (LME) can occur, which is characterized by the appearance of irregular cracks on the weld spot surface. However, the impact of LME cracks on the mechanical properties of joints remains unclear.

Unpacking Learners' Global Perspective and Willingness to Communicate in English among Different English Proficiency University Students in China.

The correlation between students' Global Perspective (GP) and Willingness to Communicate in a second language (L2 WTC), particularly in the context of China, remains an under-explored area. Additionally, few studies have compared the GP and WTC among students with varying English proficiency levels or examined whether there are specific similarities and differences among these students. This study aimed to bridge these gaps within the context of traditional and English Medium Instruction (EMI) universities in China.

Machine learning-assisted construction of COPD self-evaluation questionnaire (COPD-EQ): a national multicentre study in China.

Background: Approximately 70% of chronic obstructive pulmonary disease (COPD) is underdiagnosed worldwide. We aimed to develop and validate a COPD self-evaluation questionnaire (COPD-EQ) that is better suited for COPD screening in China.

Methods: We developed a primary version of COPD-EQ based on the Delphi method.
