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,

Das Wort "souverän" auf der einen Seite und "Google", "AWS", "SAP" und "Azure" (etc.) auf der anderen, funktionieren nur zusammen in einem Satz, wenn sie inhaltlich mit einem eindeutigen "NICHT" verbunden sind.
Kommerzielle closed source-Produkte können niemals, nie-nie-niemals irgendeine Form von Souveränität bieten.
Wer etwas anderes behauptet, hat entweder keine Ahnung oder lügt.

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: Why kinetically stable oil droplets in water spontaneously acquire a negative charge remains one of the most vigorously debated questions in interfacial science. Here, we combine neural-network based deep potential molecular dynamics with a data-driven and information theory approach to probe the real-space electron density at an extended decane-water interface. While decane-water clusters show nearly symmetric forward and backward charge transfer (CT) and thus negligible net CT, the extended interface displays a systematic electronic asymmetry, yielding a net CT from water to the hydrocarbon phase producing an average surface charge density of $\sim0.006~e^{-}\,\mathrm{nm}^{-2}$ on the oil phase. This imbalance is accompanied by much larger intra-phase self-polarization, particularly within the hydrocarbon phase, demonstrating that collective many-body polarization dominates the interfacial electronic response. Structural analysis reveals an asymmetry between forward C--H$\cdots$O and backward O--H$\cdots$C motifs, providing a microscopic origin for a net CT from one phase to the other. Curiously, both the water O--H and decane C--H covalent bonds incur subtle contractions which originate from a response to the charge-separation layers at the interface. These features are fully consistent with the weak improper hydrogen-bonds forming at the oil-water interface that results in blue-shifts of the C-H modes.

The Pentagon has met with senior executives of Ford Motor and General Motors
to gauge whether the auto industry could help the military acquire vehicles, munitions or other hardware more quickly and at lower costs.
The conversations are in the very early stages, and relate to the possible production of components by the companies, not entire weapons systems.
No specific projects are currently being negotiated, the people said.
The discussions with automakers underscore …

Pentagon Seeks Help From Ford and G.M.
Concerned about the slow pace and high cost of weapons production, Pentagon officials have begun talks with General Motors and Ford Motor about producing certain parts.
