Capillary processes in extraterrestrial contexts
The Earth is no longer the only known celestial body containing one or more liquid phases. The Cassini spacecraft has discovered seas of hydrocarbons at the surface of Titan, while a series of corroborating evidences argue in favour of the existence of an aqueous ocean beneath the icy crust of several moons. Capillarity embraces a family of physical processes occurring at the free surface of a liquid. These phenomena depend on the liquid properties and on the local planetary conditions. Capilla…

“The two justices whose comings and goings are probably of the most interest to the general public appear to be shielding some of that travel by solely availing themselves of security resources not subject to open records requests,” FTC’s Gabe Roth said.
“Maybe there’s an innocuous explanation for this. But given the opacity we’ve seen from the Court, especially when it comes to travel, maybe there’s not.”

Dozens of Previously Unreported SCOTUS Trips in New Marshals Documents — But Justice Thomas and the Chief Justice Are Nowhere to be Found - Fix the Court
Ditching deputy marshals at the gates of Bohemian Grove. An extravagant birthday party at Lincoln Center. Religious services at a Brooklyn theater. Annual vacations to Colorado. Dialing in to oral argument from Florida. “Business meetings.” A meeting with a congressman. These are a few of the justices’ more than 200 previously unreported activities that appear in the 4,042 […]

Abstract: We demonstrate a new approach for the metrology of microwave fields based on the trap-loss-spectroscopy of cold Rydberg atoms in a magneto-optical trap. Compared to state-of-the-art sensors using room-temperature vapors, cold atoms allow longer interaction times, better isolation from the environment and a reduced Doppler effect. Our approach is particularly simple as the detection relies on fluorescence measurements only. Moreover, our signal is well described by a two-level model across a broad measurement range, allowing in principle to reconstruct the amplitude and the frequency of the microwave field simultaneously without the need for an external reference field. We report on a scale factor linearity at the percent level and no noticeable drifts over two hours, paving the way for new applications of cold Rydberg atoms in metrology such as calibrating blackbody shifts in state-of-the-art optical clocks, monitoring the Earth cryosphere from space, measuring the cosmic microwave background or searching for dark matter.

Combinatorics of Correlated Equilibria
We study the correlated equilibrium polytope $P_G$ of a game $G$ from a combinatorial point of view. We introduce the region of full-dimensionality for this class of polytopes and prove that it is a semialgebraic set for any game. Using a stratification via oriented matroids, we propose a structured method for describing the possible combinatorial types of $P_G$, and show that for $(2 \times n)$-games, the algebraic boundary of the stratification is a union of coordinate hyperplanes and binomia…

Did you ever believe that Hunter Biden took a #laptop full of incriminating information into a computer repair shop and abandoned it there? That the repair shop decided to examine its contents and transmit them to Rudy Giuliani and Steve Bannon?
Of course not. Because you have more common sense than reporters and editors at every major news organization.
The whole thing was a Russian disinfor…

The Interaction Fidelity Model: A Taxonomy to Distinguish the Aspects of Fidelity in Virtual Reality
Fidelity describes how closely a replication resembles the original. It can be helpful to analyze how faithful interactions in virtual reality (VR) are to a reference interaction. In prior research, fidelity has been restricted to the simulation of reality - also called realism. Our definition includes other reference interactions, such as superpowers or fiction. Interaction fidelity is a multilayered concept. Unfortunately, different aspects of fidelity have either not been distinguished in sc…
