OpenAI has revealed a breakthrough proof that overturns a nearly 80-year-old geometry conjecture posed by Paul Erdős.

Abstract: A dual-polarization frequency-selective rasorber (FSR) with two absorptive bands at both sides of a passband is presented. Based on the characteristic mode analysis, a circuit analog ...

Abstract: The seafloor seismic acquisition systems, such as ocean-bottom node (OBN) and cable ocean-bottom cable (OBC) arrays, provide multicomponent data essential for high-resolution imaging. Among ...
