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.

Large eddy simulation of turbulent swirl-stabilized flames using the front propagation formulation: impact of the resolved flame thickness

Abstract: This work extends the front propagation formulation (FPF) combustion model to large eddy simulation (LES) of swirl-stabilized turbulent premixed flames and investigates the effects of resolved flame thickness on the predicted flame dynamics. The FPF method is designed to mitigate the spurious propagation of under-resolved flames while preserving the reaction characteristics of filtered flame fronts. In this study, the model is extended to account for non-adiabatic effects and is coupled with an improved sub-filter flame speed estimation that resolves the inconsistency arising from heat-release effects on local sub-filter turbulence. The performance of the extended FPF method is validated by LES of the TECFLAM swirl-stabilized burner, where the results agree well with experimental measurements. The simulations reveal that the stretching of vortical structures in the outer shear layer leads to the formation of trapped flame pockets, which are identified as the physical mechanism responsible for the secondary temperature peaks observed in the experiment. The prediction of this phenomenon is shown to be strongly dependent on the resolved flame thickness, when the filter size is used for modeling sub-filter flame wrinklings. Without proper modeling of the chemical steepening effects, the thickness of the resolved flame brush is over-predicted, causing the flame consumption rate to be under-estimated. Consequently, the flame brush detaches from the outer shear layer, resulting in a failure to capture the flame pockets and the associated secondary temperature peaks.

Abstract: The n2EDM experiment at the Paul Scherrer Institute aims to conduct a high-sensitivity search for the electric dipole moment of the neutron. Magnetic stability and control are achieved through a combination of passive shielding, provided by a magnetically shielded room (MSR), and a surrounding active field compensation system by an Active Magnetic Shield (AMS). The AMS is a feedback-controlled system of eight coils spanned on an irregular grid, designed to provide magnetic stability to the enclosed volume by actively suppressing external magnetic disturbances. It can compensate static and variable magnetic fields up to $\pm 50$ $\mu$T (homogeneous components) and $\pm 5$ $\mu$T/m (first-order gradients), suppressing them to a few $\mu$T in the sub-Hertz frequency range. We present a full finite element simulation of magnetic fields generated by the AMS in the presence of the MSR. This simulation is of sufficient accuracy to approach our measurements. We demonstrate how the simulation can be used with an example, obtaining an optimal number and placement of feedback sensors using genetic algorithms.

Trump is 'not protecting Americans'
Senate minority leader, Chuck Schumer, said Democrats were right to remain seated when Trump called on the crowd to stand if they believed in protecting US citizens over undocumented immigrants,
a line that Republicans are now using to call out Democrats.
“Bottom line is very simple,
we agree we need to protect Americans.
He’s not,”
Schumer told CNN this morning.
“By his reckless ICE agency in Minnesota,
