Solving the Decision Principal Ideal Problem with Pre-processing
The principal ideal problem constitutes a fundamental problem in algebraic number theory and has attracted significant attention due to its applications in ideal lattice based cryptosystems. Efficient quantum algorithm has been found to address this problem. The situation is different in the classical computational setting. In this work, we delve into the relationship between the principal ideal problem and the class field computation. We show that the decision version of the problem can be sol…

»Beschleunigte Erdrotation: Warum eine fehlende Sekunde zum globalen IT-Problem:
[…] Nun könnte erstmals in der Geschichte der Zeitmessung das Gegenteil notwendig werden: eine negative Schaltsekunde […]«
Für die IT-Sicherheit ist ua der Mond und seine Zeit mitverantwortlich, weil wir eine Sekunde hinterher sind im realen Leben und digital eine Sekunde in der Zukunft – Dinge gibt es in der heutigen Zeit O_O

Beschleunigte Erdrotation: Warum eine fehlende Sekunde zum globalen IT-Problem wird | t3n
Etwas Grundlegendes hat sich verändert. Unbemerkt von den meisten, aber mit potenziell gravierenden Folgen für die digitale Welt. Unser Planet hat, zumindest vorübergehend, einen neuen Takt gefunden. Was physikalisch fasziniert, bereitet Techniker:innen Kopfzerbrechen. Die Erde beschleunigt seit einigen Jahren ihre Rotation. Diese Beschleunigung ist zwar minimal, aber messbar: An Tagen wie dem 9. Juli, 22. […]

A space-time interface-fitted method for moving-subdomain distributed control problems with energy regularization
This paper investigates a space-time interface-fitted approximation of a moving-interface optimal control problem with energy regularization. We reformulate the optimality conditions into a variational problem involving both the state and adjoint. This problem is shown to be equivalent to our optimal control problem. Based on fully unstructured, space-time interface-fitted meshes, we propose and analyze a Petrov-Galerkin approximation of the problem. An optimal error estimate with respect to a …

With DJI's powerful ebike motors, Bosch is afraid of upcoming regulation.
And I must admit: RIGHT. To me, an MTB with a factor 8x support has nothing to do with mountainbiking any more.

Never mind the dummy,
The Robotaxi also failed to stop for the stop sign.
Nice hit and run afterwards, though.
