Still... one of the most legendary comedy bits of all time.

You mean it fed directly into this promotional video. Having taken part as an invited expert on privacy and tech at the EU Parliament, I’ve seen firsthand how the points we raised at our meeting were entirely absent from the plenary session that followed and how the politicians went with their usual talking points and policies.
It’s good optics, though, right?

A presentation for the category of $sl(3)$ webs and an extension of the quantum $sl(3)$-invariant to tangles
We extend the $sl(3)$-polynomial invariant for links to tangles. Motivated by Kuperberg's construction of this invariant via planar trivalent graphs, we first define a category of $sl(3)$ webs and its sister linear category, and describe them via generators and relations. Then we define a functor from the category of oriented tangles to the linear category of $sl(3)$ webs, which yields an invariant for tangles and allows us to recover the $sl(3)$-polynomial invariant for links.

Planar black holes and black bounces with flat exterior
We present $n(\ge 4)$-dimensional planar black holes and black bounces with a flat exterior, which are originated by an exact solution in general relativity. The interior regions of these black objects are described by the extended dynamical region inside a non-degenerate Killing horizon of Gamboa's static plane symmetric solution with a perfect fluid obeying a linear equation of state $p=χρ$ for $χ\in[-1/3,0)$. The matter field inside the horizon is not a perfect fluid but an anisotropic fl…

Near-extremal holographic charge correlators
We analytically compute the low-temperature charge correlators in near-extremal black holes with a planar horizon and an infrared $\mathrm{AdS}_2\times \Bbb{R}^2$ extremal geometry, finding excellent agreement with numerical calculations. The analytical result consistently describes the crossover between the hydrodynamic diffusive regime at low frequencies and wavenumbers, and the quantum, zero-temperature regime at high frequencies and wavenumbers. We analytically resolve the successive collis…
