Abstract: Although full waveform inversion (FWI) is widely recognized as one of the state-of-the-art techniques in geophysical exploration, there remain several aspects of FWI that require further ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

Researchers are trying to come up with new, better ways to test AI. As a tech reporter I often get asked questions like “Is DeepSeek actually better than ChatGPT?” or “Is the Anthropic model any good?

The cyclical, now AI-fueled, “SEO is dead” panic cycle is in full swing. But here’s what most of those headlines miss: Search isn’t a platform, it’s a behavior. Whether people are typing into Google ...

Abstract: An adjoint-based inverse design method is proposed for efficient topology optimization of microwave components. In this approach, the postprocessing adjoint analytical topology formula is ...

Just wanted to ask if I have the right understanding of what algorithms are being used for each adjoint method, as the documentation does not link each method to a paper or reference.

The Artificial Potential Field (APF) algorithm has been widely used for collision avoidance on unmanned ships. However, traditional APF methods have several defects that need to be addressed. To ...

Control of complex flows plays a central role in many processes, where the typical parameter space for optimization is huge. Breakthroughs in direct numerical simulation over the last century have ...
