We prove that the density of Costas arrays among permutation matrices decays exponentially, solving a core problem in the theory of Costas arrays. The proof combines ideas from random graph theory ...
Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
Physicists Say Light Can Be Made From Nothing and Now They Have the Simulation to Prove It An Oxford-led team simulation just brought one of physics' weirdest predictions to life.
Universe decays faster than thought, but still takes a long time Date: May 12, 2025 Source: Radboud University Nijmegen Summary: The universe is decaying much faster than thought. This is shown by ...
New precise calculation of nuclear beta decays paves the way to uncover physics beyond the standard model Theorists identify new effects needed to compute the nuclear beta decay rate with a ...
Physics simulation Physics simulations traditionally relied on solving the Navier-Stokes partial differential equations (PDEs), offering high accuracy but demanding heavy computational power, which ...
The Standard Model of particle physics predicts an asymmetry between matter and antimatter known as charge-parity (CP) violation. But the size of this asymmetry in the Standard Model is not large ...
By analyzing nuclear beta decays, physicists seek to clarify the inaccuracies in quark mixing predictions of the Standard Model and explore possibilities of new physics. Credit: SciTechDaily.com ...
Andrzej Buras explains how two rare kaon decays and four rare B-meson decays will soon probe for new physics beyond the reach of direct searches at colliders.
The gradual reduction in attention weights due to exponential decay helps the decay mask effectively guide the learning process within the self-attention framework. Gradformer achieves ...
