Spectropolarimetric synthesis of forbidden lines in MHD models of coronal bright points
The inference of the magnetic field vector from spectropolarimetric observations is crucial for understanding the physical processes governing the solar corona. We investigate which information on the magnetic fields of coronal bright points (CBP) can be gained from the intensity and polarization of the Fe XIII 10747 A, Fe XIV 5303 A, Si X 14301 A, and Si IX 39343 A forbidden lines. We apply the P-CORONA synthesis code to a CBP model in the very low corona, obtained with the Bifrost code, and t…

AI-enhanced maps reveal hidden streams for restoration
A dataset unveiled today more than doubles the documented stream miles in the Chesapeake Bay Watershed, elevating the total from approximately 150,000 to nearly 350,000 miles. The Hyper-Resolution Hydrography Data used to generate the new stream maps stems from a collaboration between the University of Maryland, Baltimore County (UMBC), the Environmental Protection Agency's Chesapeake Bay Program (CBP), and the Chesapeake Conservancy (CC), including UMBC alumni at CBP and CC.

Internal emails: ICE is using Mobile Fortify, an app that uses facial recognition and fingerprint scanning via phone cameras to identify people in the field (Joseph Cox/404 Media)

ICE Is Using a New Facial Recognition App to Identify People, Leaked Emails Show
The new tool, called Mobile Fortify, uses the CBP system which ordinarily takes photos of people when they enter or exit the U.S., according to internal ICE emails viewed by 404 Media. Now ICE is using it in the field.

There are undoubtedly morally justified uses of facial recognition technology, but improving and refining these technologies directly enables racist policies.

Hey, #DeltaAirlines, #AmericanAirlines, and #UnitedAirlines: selling passenger data to the Feds without requiring a warrant, are you?

Airlines Secretly Selling Passenger Data to the Government - Schneier on Security
This is news: A data broker owned by the country’s major airlines, including Delta, American Airlines, and United, collected U.S. travellers’ domestic flight records, sold access to them to Customs and Border Protection (CBP), and then as part of the contract told CBP to not reveal where the data came from, according to internal CBP documents obtained by 404 Media. The data includes passenger names, their full flight itineraries, and financial details. Another article. EDITED TO ADD (6/14):…

Taming Wild Branches: Overcoming Hard-to-Predict Branches using the Bullseye Predictor
Branch prediction is key to the performance of out-of-order processors. While the CBP-2016 winner TAGE-SC-L combines geometric-history tables, a statistical corrector, and a loop predictor, over half of its remaining mispredictions stem from a small set of hard-to-predict (H2P) branches. These branches occur under diverse global histories, causing repeated thrashing in TAGE and eviction before usefulness counters can mature. Prior work shows that simply enlarging the tables offers only marginal…
