Abstract: To compensate the energy loss of traditional passive space-time-coding metasurface, an amplifying space-time-coding metasurface (ASTCM) is proposed in this work. The ASTCM can achieve more ...

Abstract: Coding metasurfaces (MSs) provide an effective strategy for designing highly integrated devices due to their powerful ability to flexibly manipulate the wavefront of electromagnetic (EM) ...

So, you want to get better at Java coding? That’s awesome. The thing is, just watching videos or reading books only gets you so far. You really need to get your hands dirty and write some code.

A fundamental challenge for GUI agents is robustly grounding natural language instructions, which requires not only precise spatial alignment (locating elements accurately) but also correct semantic ...
