Both imploding nuclear superpowers from the Cold War

From Ukraine to Gaza, from Venezuela to Greenland, events are moving very quickly, and this will not likely let up in 2026.
We need difficult, pivotal changes if we are to meet the threats to our sovereignty.

The dramatic transition of the extreme red supergiant WOH G64 to a yellow hypergiant: #stars
The big problem I have with government IT procurement decision makers - here in Aotearoa NZ and elsewhere - is that they *don't _revile_ US BigTech*. If they've paid the slightest bit of attention to their field, they know they have *every reason to do so*. So they definitely should. If they did, the world would be a better place, by far.
At present, our bureaucrats are licking the boots of the oppressors of their nations, the defilers of their sovereignty.

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.
