The Distribution Shift Problem in Transportation Networks using Reinforcement Learning and AI
The use of Machine Learning (ML) and Artificial Intelligence (AI) in smart transportation networks has increased significantly in the last few years. Among these ML and AI approaches, Reinforcement Learning (RL) has been shown to be a very promising approach by several authors. However, a problem with using Reinforcement Learning in Traffic Signal Control is the reliability of the trained RL agents due to the dynamically changing distribution of the input data with respect to the distribution o…

So my other big piece of the day is an inside look at the struggle for the future of the CVE program that just went live at CyberScoop.
Many thanks to Jay Jacobs of Empirical Security, Nick Leiserson of the Institute for Security and Technology, Mitchel Herckis of Wiz, Brian Fox of Sonatype, Peter Allor of the CVE Foundation, Ben Edwards of Bitsight and a few experts who go unnamed for their insight.

Behind the struggle for control of the CVE program
Following a funding scare that nearly shuttered the CVE program, outside experts and CISA are positioning to take charge of the 25-year-old system before the next funding crisis hits.

Global well-posedness and Gevrey regularity of Navier-Stokes equations in critical Triebel-Lizorkin-Lorentz spaces

Global well-posedness and Gevrey regularity of Navier-Stokes equations in critical Triebel-Lizorkin-Lorentz spaces
The properties of solutions to Navier-Stokes equations, including well-posedness and Gevrey regularity, are a class of highly interesting problems. Inspired by the property of Lorentz type spaces that they reflect the distribution of large value points, we establish the global well-posedness of Navier-Stokes equations in critical Triebel-Lizorkin-Lorentz space. Based on this, we obtained the Gevrey regularity of the mild solution. Compared with Germain-Pavlović-Staffilani (2007), the Gevrey re…

Single-shot sorting of Mössbauer time-domain data at X-ray free electron lasers
Mössbauer spectroscopy is widely used to study structure and dynamics of matter with remarkably high energy resolution, provided by the narrow nuclear resonance line widths. However, the narrow width implies low count rates, such that experiments commonly average over extended measurement times or many x-ray pulses (``shots''). This averaging impedes the study of non-equilibrium phenomena. It has been suggested that X-ray free-electron lasers (XFELs) could enable Mössbauer single-shot measure…

Bumble bees pollinated linden flowers 24 million years ago, fossil evidence shows
An international research team led by the Department of Botany and Biodiversity Research at the University of Vienna has made an extraordinary discovery: fossilized lime blossoms and fossilized bumble bees were found in 24-million-year-old sediments at the Enspel Fossil-Lagerstätte (Rhineland-Palatinate, Germany)—along with evidence of their interaction in the form of preserved pollen grains. These findings show that bumble bees were already among the most important pollinators of linden (or…

Content warning: "austerity", "integration", UK

Good piece from Nesrine Malik.
"The supposedly unifying thread of all these new policies is “integration”: this mythical concept that has taken on the quality of a religious ideal. ... It depends upon the children’s centre that links parents to others in the community and pools advice and resources. It depends on the libraries that provide literature and history and local knowledge. It depends on youth clubs and midwife visits and community centres and public-sector workers ...
"Yet all of these services have been hollowed out by years of austerity, pushing people back into their own small networks and atomised lives."
I'm remembering when one of the Nottingham leisure centres was closed, a youth worker explaining that the youth club there had been neutral ground for local kids from different areas to be able to hang out safely. I think it's unlikely the benefits of that had been costed in when the council decided to close the place. Even purely economically, I think it was a false economy, let alone quality of life and community-building.
