Hamburg police have understood what “defensive #democracy” means:
“Does flying the 🏳️‍🌈 flag violate the neutrality requirement? No! Our neutrality means political impartiality – but not neutrality in value. The flag represents values like diversity, tolerance & equality of rights, which are deeply embedded in our constitution.
Positioning ourselves against hate & discrimi…

Embodied Navigation Foundation Model
Navigation is a fundamental capability in embodied AI, representing the intelligence required to perceive and interact within physical environments following language instructions. Despite significant progress in large Vision-Language Models (VLMs), which exhibit remarkable zero-shot performance on general vision-language tasks, their generalization ability in embodied navigation remains largely confined to narrow task settings and embodiment-specific architectures. In this work, we introduce a…

Neue Unterstützungszusagen für NATO-Einsatz "Eastern Sentry"
Für den neuen NATO-Einsatz zur Sicherung des Luftraums an der Ostflanke gibt es weitere Unterstützungszusagen. Wie das oberste Hauptquartier der alliierten Streitkräfte in Europa (Shape) im belgischen Mons mitteilte, wird Spanien in Kürze Beiträge ankündigen. Britische Kampfjets werden sich am Schutz des polnischen Luftraums beteiligen, te…

NATO will Flanke zu Russland stärken
Die NATO zieht Konsequenzen aus der Verletzung des polnischen Luftraums durch russische Drohnen. Man starte zum Schutz der Ostflanke eine neue Militäroperation, so Generalsekretär Rutte. Dafür soll unter anderem die Flugabwehr ausgebaut werden.

IP Models for Minimum Zero Forcing Sets, Forts, and Related Graph Parameters
Zero forcing is a binary coloring game on a graph where a set of filled vertices can force non-filled vertices to become filled following a color change rule. In 2008, the zero forcing number of a graph was shown to be an upper bound on its maximum nullity. In addition, the combinatorial optimization problem for the zero forcing number was shown to be NP-hard. Since then, the study of zero forcing and its related parameters has received considerable attention. In 2018, the forts of a graph were…

Effects of rough boundary and nonzero boundary conditions on the lubrication process with micropolar fluid
The lubrication theory is mostly concerned with the behavior of a lubricant flowing through a narrow gap. Motivated by the experimental findings from the tribology literature, we take the lubricant to be micropolar fluid and study its behavior in a thin domain with rough boundary. Instead of considering (commonly used) simple zero boundary condition, we impose physically relevant (nonzero) boundary condition for microrotation and perform asymptotic analysis of the corresponding 3D boundary valu…

Geometric Optimization and IPA-Induced Dispersion Tuning in Solid-Core Photonic Crystal Fibers
This study presents a numerical investigation of solid-core photonic crystal fibers with circular and hexagonal cladding geometries. The goal is to optimize optical parameters for nonlinear photonics and environmental sensing. Full-vectorial simulations using FDTD, PWE, and FDE are used to analyze the effects of core diameter, pitch, and air filling fraction on the zero-dispersion wavelength, nonlinear coefficient, effective mode area, and confinement loss. Reducing the core diameter from 2.4 t…

Beim Schreiben neige ich (anders als beim mündlichen Brabbeln) zur Kürze. Aber zu Gabriele Mainettis neuem Film LA CITTÀ PROIBITA (deutscher Titel aus unklaren Gründen KUNG FU IN ROME <- ja, in englischer Schreibweise...) gab es überraschend viel zu sagen. Mein Text im Perlentaucher.

Unlocking Altermagnetism in Antiferromagnetic 2D Films via Adsorption
Altermagnets, characterized by zero net magnetization and momentum-dependent spin splitting, have recently garnered significant attention due to their potential applications in a variety of fields. Here, we propose a symmetry-engineering strategy to unlock altermagnetism in two dimensional (2D) antiferromagnetic systems via surface adsorption of atoms or molecules. By employing spin group theory, we systematically demonstrate that selectively breaking symmetry operations, specifically those pro…
