Talks kick off Monday between U.S. and Mexican trade officials.
The North American economies could agree to renew the
US-Mexico-Canada Agreement,
or USMCA as it is for another 16 years
— a prospect that appears unlikely.
Or they could keep working on ways to improve it;
Under a convoluted renewal process, they have until 2036 to reach an agreement
Much of this bustling cross-border commerce is duty-free, thanks to the US-Mexico-Canada Agreement, that Do…

Tricky negotiations begin Monday to renew a trade pact between the United States, Mexico and Canada — The Associated Press
Every day more than $4 billion worth of goods cross the United States’ borders with Canada and Mexico – U.S. auto parts headed for car factories in northern Mexico, cartons of Mexican avocados bound for California supermarkets, Canadian aluminum destined to become cans of Campbell Soup.

The definitive chart for avocados. Especially when you're dumb enough to buy two bags worth. 🤦‍♂️

Instead of digging a bit deeper into factors affecting housing affordability, news articles like this uncritically accept YIMBY's Leora Ross's “Thanks to years of advocacy at the state level to pass laws like AB 2011, housing proposals like these will bring thousands of homes to the Bay Area and make it easier and more affordable for people to live here.”
There are so many factors affecting affordability - and this is ignored. WHY?
Plans for nearly 4,000 homes over Saf…

[Paraphrasing Felix Bloch speaking to Heisenberg]...space was simply the field of linear operations.
[Heisenberg] Nonsense, space is blue and birds fly through it.
[Bloch, explaining] What he meant was that it was dangerous for a physicist to describe Nature in terms of idealised abstractions too far removed from the evidence of actual observation.
Tell it! Yay Heisenberg!

Guten Morgen,
heute sitze ich mal wieder früher am PC als geplant. Früh aufstehen, wer richtig #Moos machen will.
Ich weiß, wo es von ganz alleine wächst :-)
Schönen Tag :coffeepot: 🙂

Abstract: This paper presents experimental validation of the homogenized harmonic balance finite element method (HomHBFEM), which we have developed as a dedicated simulation technique for magnets with fast excitation cycles, in particular the fast corrector (FC) magnets for PETRA IV at DESY. The HomHBFEM allows efficient three-dimensional nonlinear eddy-current simulations of laminated magnets at elevated frequencies with a relatively coarse finite element (FE) mesh and without computationally expensive time-stepping. This is achieved by combining a frequency-domain-based homogenization technique with the harmonic balance FE method. The simulation results for the magnetic flux density along the axis of the FC magnets as a function of frequency and the resulting integrated transfer function (ITF) are compared to Hall probe and search coil measurements of the first prototype FC magnet for PETRA IV. A good agreement between simulated and measured ITFs is achieved for excitation frequencies from 10 Hz to 10 kHz.

For a year, the Trump Justice Department has been on an odd mission:
to assist a former FBI informant with ties to Russian intelligence who ended up in prison for passing disinformation about Joe Biden to the bureau.
His crime deeply affected American politics.
The false claim he slipped to the FBI
—that Biden and his son Hunter each were paid a $5 million bribe by a Ukrainian energy company
—became the main evidence in the House Republicans’ reckless and ill-fate…

Trump’s DOJ is helping a convicted FBI informant tied to Russian intelligence
Alexander Smirnov’s lies about Joe Biden were at the core of the GOP’s impeachment drive.
