OpenAI Employees Have Cashed Out $3 Billion in Shares
My colleague Sri Muppidi broke the news Wednesday of OpenAI’s latest fundraising talks as it seeks to raise an unprecedented $40 billion. One previously unreported detail is that SoftBank bought about $240 million in shares from a small group of current and former employees this spring.That deal ...

Ocean currents can generate electricity, and our study shows Africa's seas have some of the strongest
The world's oceans cover more than 70% of Earth's surface. They're filled with currents, some much stronger than the fastest flowing large rivers. These currents can be harnessed as clean, marine renewable energy. Marine energy is much more predictable and reliable than many other forms of renewable energy because unlike the sun and wind, which regularly do not produce electricity, ocean currents never stop moving around the planet. New research has found that the eastern and south-eastern coas…

Event generation at MEPS@NLO accuracy in neutral and charged current DIS at the EIC
We present the first hadron-level predictions at MEPS@NLO precision for both neutral and charged current DIS at the EIC and the first application of the MEPS@NLO technique to charged current DIS in general. We critically examine state-of-the-art inclusive predictions using multi-leg merging techniques, contrasting perturbative and non-perturbative uncertainties. We study typical kinematic DIS observables as well as jet measurements and 1-jettiness with realistic cuts implied by expected and pas…

Nonequilibrium fluctuation-response relations for state-current correlations
Recently, novel exact identities known as Fluctuation-Response Relations (FRRs) have been derived for nonequilibrium steady states of Markov jump processes. These identities link the fluctuations of state or current observables to a combination of responses of these observables to perturbations of transition rates. Here, we complement these results by deriving analogous FRRs applicable to mixed covariances of one state and one current observable. We further derive novel Inverse FRRs expressing …

The connection between the chromatic function and the Redei-Berge function

The connection between the chromatic function and the Redei-Berge function
There is a natural way to assign both graph and digraph to every poset. Furthermore, any graph has its chromatic function, while any digraph has its Redei-Berge function. On the level of posets, these two functions are almost identical. Here, we prove that this connection is actually a reflection of the connection between the noncommutative generalizations of these two functions. The simplicity of this relationship enables us to easily translate the properties proved for one of them to the case…

Radiative decays of $P$-wave charmed baryons in the $SU(3)$ flavor $\bf6_F$ representation
We perform a comprehensive investigation of the radiative decays of $P$-wave charmed baryons in the $SU(3)$ flavor $\mathbf{6}_F$ representation, employing the light-cone QCD sum rule approach within the framework of heavy quark effective theory. We analyze their electromagnetic transitions into ground-state charmed baryons via photon emission. When combined with the mass spectra and strong decay properties previously studied in Ref.~\cite{Yang:2021lce}, our results constitute a systematic and …
