MCWS 2026: Field for Omaha is set with OU taking the last spot
Country roads, take us to Omaha! The field for the 2026 Men's College World Series is set with all eight spots secured. No. 7 Alabama claimed the most recent spot after beating St. John's 7-2 in the Tuscaloosa Super Regional.
Unlearning's Blind Spots: Over-Unlearning and Prototypical Relearning Attack
arXiv:2506.01318v4 Announce Type: replace Abstract: Machine unlearning (MU) aims to expunge a designated forget set from a trained model without costly retraining, yet the existing techniques overlook two critical blind spots: "over-unlearning" that deteriorates retained data near the forget set, and post-hoc "relearning" attacks that aim to resurrect the forgotten knowledge. Focusing on class-level unlearning, we first derive an over-unlearning metric, OU@epsilon, which quantifies...
The Information Content of Quasar Variability Light Curves: How Well Can we Infer Stochastic Model Parameters?
arXiv:2606.01496v1 Announce Type: cross Abstract: Quasar variability, driven by multi-scale physical processing within a relativistic accretion disk, is commonly modelled with stochastic time series models. The simplest of these is the Damped Random Walk (DRW), also known as the Ornstein-Uhlenbeck (OU) process. Here, we demonstrate that, when fitting such a model to quasar light curve data, the mean of the light curve, $\mu$, should not be fixed (which is the typical approach), as this leads...
Detecting Cyber Attacks in Power System AGC Using a Drifted Ornstein-Uhlenbeck Process
arXiv:2606.02075v1 Announce Type: new Abstract: The Automatic Generation Control (AGC) system, reliant on real-time measurements over communication networks, is susceptible to stealthy false data injection attacks (FDIAs), risking equipment damage and economic losses. We propose a robust FDIA detection method using maximum likelihood estimation (MLE) of a drifted multivariate Ornstein-Uhlenbeck (OU) process.
What are Oklahoma fans doing at a Women's College ...
After Oklahoma's decade-long run of reaching the Women's College World Series ended last weekend, Betty Frederick was so upset that she told her husband, Gene, they were selling their season tickets. Laura Glardon, a Texas fan from Houston who has been sitting next to the Fredericks for years at the WCWS, worried that Betty might skip this tournament without the Sooners playing. Glardon texted to make sure she was still making the trip.
This strange new phase of matter could transform quantum technology
This strange new phase of matter could transform quantum technology - Date: - May 30, 2026 - Source: - Brown University - Summary: - By stacking custom-designed silver nanoparticles like nanoscale LEGO bricks, scientists stabilized a mysterious crystal phase that had never been observed before. The material not only solves a longstanding puzzle in materials science but also exhibits promising quantum properties at room temperature.
AI-guided catalyst turns CO₂ and waste into fertilizer at industrially relevant rates
AI-guided catalyst turns CO₂ and waste into fertilizer at industrially relevant rates Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers from the National University of Singapore (NUS) have developed a computation-guided strategy to produce urea more efficiently from carbon dioxide and nitrate. By combining large language models, density functional theory calculations and experiments, the approach identified a cadmium-modified iron oxide catalyst that maintains high urea...
Raids, stranded victims and new criminal tactics - inside Cambodia’s fight against scam centres
Raids, stranded victims and new criminal tactics - inside Cambodia’s fight against scam centres Cambodia says it is carrying out its toughest crackdown yet on online scam centres, with hundreds of facilities targeted. In the first of a two-part series, CNA goes on the ground to find victims stranded and signs of operations shifting into smaller urban sites, while experts warn that the criminal networks behind the industry remain deeply embedded. Abdul’s plan was to teach English in a Bangkok...
