Anger at the regime continues to spread,
even beyond the borders of the United States.
Millions of workers worldwide are following the fortunes of their brothers and sisters in the US
with intense sympathy for their struggle.
In Germany in particular, Trump’s actions vividly bring to mind Hitler, the Second World War and the Holocaust.
More and more people are becoming aware that a third world war can only be stopped if we succeed not only in overthrowing the…

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.

Complete blockade of Crimea and ruin of headquarters in Donbas! Why are Russian elites fleeing?: https://benborges.xyz/2026/02/24/complete-blockade-of-crimea-and.html
AI companies are raising at valuations that require them to grow at rates that are only achievable by chasing the broadest possible market with the most generic possible product.
A company that raises at a $500M valuation needs to show a path to billions in revenue,
which means it can't afford to be a niche tool that does one thing brilliantly for a specific audience.
It has to be a platform, horizontal, aimed at enterprise, built for no one in particular.

I have the feeling that the world is focusing too much on the energy/oil consequences of the war against Iran and not thinking enough about all the other terrible effects and consequences this war could have, for the region and the world….with Trump making all mistakes possible in handling this war…

Five people were arrested following hundreds of investigative hours following 💥 the shooting of Judge Steven Meyer and his wife, Kimberly, in Lafayette Indiana
on Jan. 18.
Both victims were in a stable condition following the attack,
which happened around 2:17 p.m.
The judge was injured on an arm, his wife on her hip.
Raylen Ferguson, 38, from Lexington, Kentucky;

Unlike his predecessors,
Trump does not even pretend that his imperialism serves any purpose nobler than American domination
For Trump, “America first” didn’t imply any legal or moral opposition to foreign invasions.
To the contrary, he criticized Bush for not seizing Iraq’s oil.
He denounced regime change and nation building because they allegedly expended American blood and treasure on behalf of non-Americans.
Instead, Trump promised short wars in which onl…
A trial date has been set for Trump's $10 billion lawsuit against the BBC.
On Thursday, Judge Roy K. Altman of the Southern District of Florida set a provisional start date of ⭐️February 15, 2027, for a two-week trial.
The lawsuit was filed following the release of an episode from Panorama,
the BBC's investigative documentary series, titled
"Trump: A Second Chance?"
In it, the BBC cut together two parts of Trump's January 2021 speech to …
