Angular momentum dynamics of vortex particles in accelerators
Experiments with spin-polarized beams of leptons and hadrons typically employ plane-wave states with definite momenta and energies. In contrast, vortex states represent cylindrical waves carrying a well-defined orbital angular momentum projection along the propagation direction. This projection can be arbitrarily large, endowing such particles with magnetic moments orders of magnitude greater than those of plane-wave states. Consequently, vortex particles could complement - or even replace - sp…

Jeg forlod den sidste flok sommerfestdeltagere for godt en halv time siden og tillod mig at skrive en sms til en af kollegerne om de måske kunne stille lidt af den tiloversblevne mad på kŸl så det kan spises i morgen (og så sendte jeg en lille grædesmiley over at min bŸtte med dessert var forsvundet i oprydningen).
Hun har lige sendt mig disse billeder 😭♥️😂

Physics-Informed Neural Networks for Control of Single-Phase Flow Systems Governed by Partial Differential Equations
The modeling and control of single-phase flow systems governed by Partial Differential Equations (PDEs) present challenges, especially under transient conditions. In this work, we extend the Physics-Informed Neural Nets for Control (PINC) framework, originally proposed to modeling and control of Ordinary Differential Equations (ODE) without the need of any labeled data, to the PDE case, particularly to single-phase incompressible and compressible flows, integrating neural networks with physical…

Delighted to see these two new papers come out in Nature (they've been on bioRxiv for a while).
How does Pavlov's dog learn that the bell predicts the food? One answer is that the bell appears ``close'' in time to the food and that enables learning. We're certain that dopamine has something to do with learning these kinds of associations. But the definition of ``close'' in time is actually really difficult to pin down. You can get associations over prett…

Here’s what Florida state Sen. Ileana Garcia, a Republican and founder of Latinas for Trump, had to say about ICE’s raids:
This is not what we voted for…
I understand the importance of deporting criminal aliens,
but what we are witnessing are arbitrary measures to hunt down people who are complying with their immigration hearings
— in many cases, with credible fear of persecution claims,
all driven by a Miller-like desire to satisfy a self-fabricated deportation…

David Barton’s Defense of ICE Actions in LA is as Wrong as His History Lessons
David Barton's propaganda on current events is every bit as believable as his Christian nationalist history.

Adjoints of Polytopes: Determinantal Representations and Smoothness
In this article we study determinantal representations of adjoint hypersurfaces of polytopes. We prove that adjoint polynomials of all polygons can be represented as determinants of tridiagonal symmetric matrices of linear forms with the matrix size being equal to the degree of the adjoint. We prove a sufficient combinatorial condition for a surface in the projective three-space to have a determinantal representation and use it to show that adjoints of all three-dimensional polytopes with at mo…

Demonstrating Interoperable Channel State Feedback Compression with Machine Learning
Neural network-based compression and decompression of channel state feedback has been one of the most widely studied applications of machine learning (ML) in wireless networks. Various simulation-based studies have shown that ML-based feedback compression can result in reduced overhead and more accurate channel information. However, to the best of our knowledge, there are no real-life proofs of concepts demonstrating the benefits of ML-based channel feedback compression in a practical setting, …

On Friday, Right Wing Watch reported that President Donald Trump's religious-right activists have been nearly unanimous in their demand that the Trump administration lend its full support to Israel in its growing conflict with Iran because they believe that it is key to bringing about the End Times and the return of Jesus Christ.
On Saturday, after Trump ordered U.S. airstrikes on Iranian nuclear facilities, MAGA cultist and self-proclaimed Christian nationalist Lance Wallnau immed…
