Abstract: In this paper, two-dimensional (2-D) direction of arrival estimation based on the fourth-order difference co-array (FODCA) is studied. By analyzing the virtual sensor positions in FODCA, the ...

Abstract: Difference-frequency-based ultrasound imaging has emerged as a promising new modality in medical imaging, allowing for high-contrast elastographic imaging to diagnose conditions such as ...

I design and deploy high-impact systems built on LLMs, local inference, and agent architectures, working close to real p ...
