Sigh, well I was feeling good about getting an ebike but I stopped by a local shop and the model I was looking at is pretty much sold out everywhere. They do have newer models ($more expensive$) and some other modes so I may need to do up that whole spreadsheet of features to compare things.

I have a question about the following:
Space-X satellites are relatively low orbit - they go around the world, their radio/signal footprint on the ground goes around the world with them.
So how does a single country, the US, issue "license" for radio spectrum that apply outside of the US geographic borders?
"SpaceX buys wireless spectrum from EchoStar in $17 billion deal"

They brought it upon themselves by not locking their computer, and a prompt open on the screen.

Morphology of Polarization States in Strained Ferroelectric Films
Ferroelectric thin films under epitaxial strain exhibit a variety of vortex-like topological polarization textures. To analyze them, we build on the Ginzburg-Landau-Devonshire framework and extend the previously introduced soft-domain approach. This formulation provides a compact variational theoretical description of polarization morphologies in strained PbTiO$_3$ films. It yields phase diagrams as a function of temperature, strain, and thickness, and clarifies the morphological structure of e…

Taming Data Challenges in ML-based Security Tasks: Lessons from Integrating Generative AI
Machine learning-based supervised classifiers are widely used for security tasks, and their improvement has been largely focused on algorithmic advancements. We argue that data challenges that negatively impact the performance of these classifiers have received limited attention. We address the following research question: Can developments in Generative AI (GenAI) address these data challenges and improve classifier performance? We propose augmenting training datasets with synthetic data genera…

Some French news publishers have signed agreements with unions to redistribute revenue from AI licensing deals to journalists; Le Monde redistributes 25% (Andrew Deck/Nieman Lab)

Some French publishers are giving AI revenue directly to journalists. Could that ever happen in the U.S.?
Le Monde agreed to give journalists 25% of revenue from licensing deals with OpenAI and Perplexity. Now, other French publishers are following suit.
