Beam-Plasma Collective Oscillations in Intense Charged-Particle Beams: Dielectric Response Theory, Langmuir Wave Dispersion, and Unsupervised Detection via Prometheus

Announce Type: replace Abstract: We develop a theoretical and computational framework for beam-plasma collective oscillations in intense charged-particle beams at intermediate energies (10-100 MeV). In Part I, we formulate a kinetic field theory governed by the Vlasov-Poisson system, deriving the Lindhard dielectric function and random phase approximation (RPA) polarization tensor for three beam distribution functions. We prove via the dielectric function epsilon(omega,q)=0 the existence of...

From Detection to Recovery: Operational Analysis on LLM Pre-training with 504 GPUs

Announce Type: replace Abstract: Large-scale AI training is now fundamentally a distributed systems problem, and hardware failures have become routine operating conditions rather than rare exceptions. Public operational evidence from production training clusters, however, remains scarce.

Quote of the day by Idris Elba

Idris Elba didn't just become an actor. From 'The Wire' to 'Luther' to 'Beasts of No Nation' to 'The Jungle Book' to 'Thor.' He has been in some of the most celebrated and culturally significant productions in both television and film.

'Disclosure Day': Will Steven Spielberg deliver an audacious on-screen alien?

Filmmakers have shaped our perception of the unknown, and Steven Spielberg has had aliens on the mind for a while now. He even believes they have been to Earth and may still be amongst us. Will his depiction of alien lifeforms in his anticipated new film 'Disclosure Day' challenge audiences?

Sysadmining Like It's 2009

I'm wicked excited, it's finally here! Legacy Labs is officially starting its first ever event! For the next two months I'm going to be sysadmining like it's 2009, well sort of, I'll break down my full plan here in a second and it's a little bit anachronistic but there's a reasoning behind it.

The Biggest Tell That Something Was Written By AI

Book Dedications

To my sister, Dr. Soma Mohammed Mohammed Baroud. I write your name in full, because that is how it appeared on the white body bag that held your remains soon after the bomb was dropped. Dedications A random assortment of book dedications.
