How instructional design shapes higher-order thinking among higher education students in generative artificial intelligence-supported teaching contexts

Against the backdrop of the widespread integration of generative artificial intelligence (GAI) into higher education, previous research has yielded divergent findings regarding its relationship with students’ higher-order thinking (HOT). Moving beyond outcome-oriented discussions...

An Ultra-Wide-Angle Mechanically Steered Reflectarray Antenna (RA) Based on Non-Specular Reflection

This paper presents a non-specular reflection-based mechanically steered reflectarray antenna (RA) that achieves ultra-wide beam steering up to 80° while preserving mainlobe integrity. Conventional mechanically steered RAs are fundamentally constrained by specular reflection, whe...
