Meta’s ‘Free Expression’ Push Results In Far Fewer Content Takedowns
Meta says loosening its enforcement policies earlier this year led to fewer erroneous takedowns on Facebook and Instagram—and didn't broadly expose users to more harmful content.

Survival of the fastest -- algorithm-guided evolution of light-powered underwater microrobots
Depending on multiple parameters, soft robots can exhibit different modes of locomotion that are difficult to model numerically. As a result, improving their performance is complex, especially in small-scale systems characterized by low Reynolds numbers, when multiple aero- and hydrodynamical processes influence their movement. In this work, we optimize light-powered millimetre-scale underwater swimmer locomotion by applying experimental results - measured swimming speed - as the fitness functi…

The most metal poor stars
The most metal-poor stars found in the Galaxy and in nearby galaxies are witnesses of the early evolution of the Universe. In a general picture in which we expect the metallicity to increase monotonically with time, as a result of the metal production in stars, we also expect the most metal-poor stars to be the most primitive objects accessible to our observations. The abundance ratios in these stars provide us important information on the first generations of stars that synthesised the nuclei …

Profiling and optimization of multi-card GPU machine learning jobs
The effectiveness and efficiency of machine learning methodologies are crucial, especially with respect to the quality of results and computational cost. This paper discusses different model optimization techniques, providing a comprehensive analysis of key performance indicators. Several parallelization strategies for image recognition, adapted to different hardware and software configurations, including distributed data parallelism and distributed hardware processing, are analyzed. Selected o…

More on the corner-vector construction for spherical designs
This paper explores a full generalization of the classical corner-vector method for constructing weighted spherical designs, which we call the {\it generalized corner-vector method}. First we establish a uniform upper bound for the degree of designs obtained from the proposed method. Our proof is a hybrid argument that employs techniques in analysis and combinatorics, especially a famous result by Xu(1998) on the interrelation between spherical designs and simplical designs, and the cross-ratio…

Flowing from the Ising Model on the Fuzzy Sphere to the 3D Lee-Yang CFT
We employ the Fuzzy Sphere regulator to study the 3D Lee-Yang CFT. The model is defined by deforming the Ising model on the Fuzzy Sphere via a purely imaginary longitudinal magnetic field. This model undergoes a quantum phase transition, whose critical point we determine and identify with the 3D Lee-Yang CFT. We show how to tune the model and find that the lowest-lying states of the Hamiltonian align well with the expected CFT spectrum. We discuss the Fuzzy Sphere estimates for the scaling dime…

Physics Will Cause the Economy to Shrink; a Look at the Next Ten Years
The world is hitting both energy and debt limits. Modeling and history show the expected results. Governments are particularly hit, as is higher education.

Finally submitted application for production access for my app on Google Play.
It's very simple and small, but took a lot more work than expected. In total six buttons. Dialogs and swiping. Zooming in and out. Small quirks appear. elements don't align. Viewpager doesn't snap to center as it should. Difference in screen resolution and themes messes up the layout.
Learned a lot, and have much more to learn. It's fun to code, but also frustrating at times. AI assis…

Cosmology with Binary Neutron Stars: Does Mass-Redshift Correlation Matter?
Next-generation gravitational wave detectors are expected to detect millions of compact binary mergers across cosmological distances. The features of the mass distribution of these mergers, combined with gravitational wave distance measurements, will enable precise cosmological inferences, even without the need for electromagnetic counterparts. However, achieving accurate results requires modeling the mass spectrum, particularly considering possible redshift evolution. Binary neutron star (BNS)…

Affine Pavings of Quiver Flag Varieties
In this article, we construct affine pavings for quiver partial flag varieties when the quiver is of Dynkin type. To achieve our results, we extend methods from Cerulli-Irelli-Esposito-Franzen-Reineke and Maksimau as well as techniques from Auslander-Reiten theory.
