Quantum fields on self-similar spacetimes

Quantum fields on self-similar spacetimes
We study (scalar, not necessarily conformal) quantum fields on self-similar spacetimes. It is shown that in states respecting the self-similarity the expectation value of the stress tensor gives rise to a quantum Lyapunov exponent $ω_q = 2$, with a leading coefficient which is geometric. Two examples for states respecting self-similarity are discussed. Our findings are in contradiction with results obtained via dimensional reduction.

This machine lets you practice baseball solo, similar to Topgolf | Arduino Blog
Topgolf has a pretty brilliant business model: let golfers do the fun stuff (driving balls at max power), without any of the complications, time commitments, or logistics of running through a full 18-hole course. Batting cages exist to do something similar for baseball, but Pete LeMaster didn’t want to practice batting — he wanted to […]

So I think I'll need to read up on it a bit. I understand that "Passkeys" try to do something similar as SSH pubkeys.
But do you know a good technical explainer of what's going on and how it works?
(Yes, I could search myself but I am looking for recommendations of articles you have read that you found helpful and clear.)

Instagram says it's making the app more 'PG-13' for teens
After outrage over teens’ well-being on Instagram erupted, the company said it would adopt the film industry’s approach and give teens a PG-13 experience.

Attention Factors for Statistical Arbitrage
Statistical arbitrage exploits temporal price differences between similar assets. We develop a framework to jointly identify similar assets through factors, identify mispricing and form a trading policy that maximizes risk-adjusted performance after trading costs. Our Attention Factors are conditional latent factors that are the most useful for arbitrage trading. They are learned from firm characteristic embeddings that allow for complex interactions. We identify time-series signals from the re…

product_space: Atlas of Economic Complexity export network
Two networks of economic products, where a pair of products are connected if they are exported at similar rates by the same countries. The data are a projection from a bipartite network of nations and the products they export. Edges weights represent a similarity score (called "proximity"). Data based on UN Comtrade worldwide trade patterns. SITC network based on the Standard International Trade Classification and HS …

On the existence of self-similar solutions to the steady Navier-Stokes equations in high dimensions
We prove that the steady incompressible Navier-Stokes equations with any given $(-3)$-homogeneous, locally Lipschitz external force on $\mathbb{R}^n\setminus\{0\}$, $4\leq n\leq 16$, have at least one $(-1)$-homogeneous solution which is scale-invariant and regular away from the origin. The global uniqueness of the self-similar solution is obtained as long as the external force is small. The key observation is to exploit a nice relation between the radial component of the velocity and the total…
