From Kinetic Theory to AI: a Rediscovery of High-Dimensional Divergences and Their Properties
Selecting an appropriate divergence measure is a critical aspect of machine learning, as it directly impacts model performance. Among the most widely used, we find the Kullback-Leibler (KL) divergence, originally introduced in kinetic theory as a measure of relative entropy between probability distributions. Just as in machine learning, the ability to quantify the proximity of probability distributions plays a central role in kinetic theory. In this paper, we present a comparative review of div…

Constraints on Kinetic Mixing of Dark Photons from Dilepton Spectra
Dark photons, the hypothetical gauge bosons associated with an additional $U(1)^{\prime}$ symmetry, can couple to Standard Model particles through a small kinetic mixing parameter $\varepsilon$ with the ordinary photon. This mechanism provides a portal between the dark sector and visible matter. In this study, we present a procedure to derive theoretical upper bounds on the kinetic mixing parameter $\varepsilon^2(M_U)$ by analyzing dilepton spectra from heavy-ion collisions across a broad energ…

Expert Insight-Based Modeling of Non-Kinetic Strategic Deterrence of Rare Earth Supply Disruption:A Simulation-Driven Systematic Framework
This study constructs a quantifiable modelling framework to simulate non-kinetic strategic deterrence pathways in rare earth supply disruption scenarios, based on structured responses from expert interviews led by Dr. Daniel O'Connor, CEO of the Rare Earth Exchange (REE). Focusing on disruption impacts on national security systems, the study proposes four core modelling components: Security Critical Zones (SCZ), Strategic Signal Injection Function (SSIF), System-Capability Migration Function (S…

Nach Meta-Einsteig: Google zieht sich offenbar bei Scale AI als Kunde zurück
Diese Woche stieg der Meta-Konzern mit 49 Prozent bei Scale AI ein. Das hat anscheinend auch Auswirkungen auf die restliche Scale-Kundschaft.

Certain kinds of gut microbes absorb toxic Pfas
“forever chemicals”
and help expel them from the body via feces,
new first-of-its-kind University of Cambridge research shows.
The findings are welcome news
as the only options that exist for reducing the level of dangerous Pfas compounds from the body are bloodletting and a cholesterol drug that induces unpleasant side effects.
The microbes were found to remove up to 75% of some Pfasfrom the gut of mice.
