Immersive Visualization of Flat Surfaces Using Ray Marching
We present an effective method for visualizing flat surfaces using ray marching. Our approach provides an intuitive way to explore translation surfaces, mirror rooms, unfolded polyhedra, and translation prisms while maintaining computational efficiency. We demonstrate the utility of the method through various examples and provide implementation insights for programmers. Finally, we discuss the use of our visualizations in outreach. We make our simulations and code available online.

Does the US have the capacity to negotiate trade agreements with 140 countries simultaneously? Alright, call it 110 because the EU covers 28 states in one go. But still. That's a lot of meeting rooms, a lot of coffee, and lot of PowerPoint. And a lot of trade wonks, they'll be pulling kids in off the streets and telling them they're now in charge of talks with, say, Chile, or Thailand, or the UAE.
And who'd want to be a trade wonk working for an embecile who doesn'…

On the Performance of Pinching-Antenna Systems (PASS) with Orthogonal and Non-Orthogonal Multiple Access
This paper conducts a comprehensive performance analysis for pinching-antenna systems (PASS) under both orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) transmission. Given the cost of waveguides, we consider a scenario where the waveguide is not deployed in all rooms, i.e., some users are beyond the line-of-sight (LoS) link service area of the PASS. Specifically, we consider a PASS where a pinching antenna in one room serves two users located in separate rooms. The wi…

There’s a new museum on Naoshima Island! This NYT article also describes the many other museums and exhibits installed there.
This is the “art island” that Lynn and I visited a couple months ago. Looks like we’ll have to go back! This time we’ll know to book rooms way in advance (and to stay longer than two nights).

Japanese Islands’ 10th Tadao Ando Museum Caps a Billionaire’s Quest
Benesse Art Site Naoshima, a sprawling art constellation on three islands, adds a 10th museum by the star architect Tadao Ando that caps the cultural quest of Soichiro Fukutake.

"Good process improvement practices include:
- standardized improvement process (pdsa, or whatever)

- Going to the gemba – improvement is done where the work is done. You must go to the where the action is. Sitting in meeting rooms, or offices, reading reports and making decisions is not the way to improve effectively.
- evidence based decision making..."
