Enhancing DSMC simulations of rarefied gas mixtures using a fast-converging and asymptotic-preserving scheme
The numerical simulation of rarefied gas mixture dynamics with disparate masses using the direct simulation Monte Carlo (DSMC) method is slow, primarily because the time step is constrained by that of the lighter species, necessitating an enormous number of evolution steps to reach a steady state. Here, we address this issue by developing a general synthetic iterative scheme, in which the traditional DSMC simulation is intermittently enhanced using a macroscopic synthetic equation. Specifically…

Variants of WormGPT, which was shut down by one of its creators last August, have emerged in BreachForums, another popular underground forum. Cato CTRL discovered previously unreported WormGPT variants that are powered by xAI’s Grok and Mistral AI’s Mixtral.

One of the reasons I love FOSS and small commercial developers is that they don’t have teams of quasi-competitive coders and/or “product managers” who have formal incentives to make visible changes to software
E.g. Apple keeps changing their decor with apparently no real goal or concept of there being objectively better or worse visual styles. Someone made Liquid Glass & probably got a bonus for doing so. Quality of UX be damned, the look must always be fresh & new.

Attached: 1 image Pocket Casts for iOS 18 on the left, Apple Podcasts for iOS 26 on the right. Between the illegible glass and the tab bar that disappears on scroll, I honestly have no idea who can take a look at this and say "Yes, that'll do it. That's good." Liquid Glass is a mess so far, *especially* on iOS. Actually pushing me to use apps without Liquid Glass.

SERVALAN: I suggest you make sure that your connection with their disappearance is never discovered. Without any records to back you up, it might be hard to explain.
BORR: There's no cause for concern, Commissioner. I was - very discrete.

ASDFormer: A Transformer with Mixtures of Pooling-Classifier Experts for Robust Autism Diagnosis and Biomarker Discovery
Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition marked by disruptions in brain connectivity. Functional MRI (fMRI) offers a non-invasive window into large-scale neural dynamics by measuring blood-oxygen-level-dependent (BOLD) signals across the brain. These signals can be modeled as interactions among Regions of Interest (ROIs), which are grouped into functional communities based on their underlying roles in brain function. Emerging evidence suggests that connectivity p…

On the Energy Distribution of the Galactic Center Excess' Sources
The Galactic Center Excess (GCE) remains one of the defining mysteries uncovered by the Fermi $γ$-ray Space Telescope. Although it may yet herald the discovery of annihilating dark matter, weighing against that conclusion are analyses showing the spatial structure of the emission appears more consistent with a population of dim point sources. Technical limitations have restricted prior analyses to studying the point-source hypothesis purely spatially. All spectral information that could help d…
