Safe Stabilization of the Stefan Problem with a High-Order Moving Boundary Dynamics by PDE Backstepping
This paper presents a safe stabilization of the Stefan PDE model with a moving boundary governed by a high-order dynamics. We consider a parabolic PDE with a time-varying domain governed by a second-order response with respect to the Neumann boundary value of the PDE state at the moving boundary. The objective is to design a boundary heat flux control to stabilize the moving boundary at a desired setpoint, with satisfying the required conditions of the model on PDE state and the moving boundary…

Boundary actions of CAT(0) spaces: topological freeness and applications to $C^*$-algebras
In this paper, we study topological dynamics on the visual boundary and several combinatorial boundaries associated to $\operatorname{CAT}(0)$ spaces. Through verifying the freeness of Myrberg points on the boundaries, we prove that a large class of these boundary actions are topologically free strong boundary actions. These include certain visual boundary actions obtained from proper isometric actions of groups on proper $\operatorname{CAT}(0)$ spaces with rank-one elements, horofunction bound…

Online Generic Event Boundary Detection
Generic Event Boundary Detection (GEBD) aims to interpret long-form videos through the lens of human perception. However, current GEBD methods require processing complete video frames to make predictions, unlike humans processing data online and in real-time. To bridge this gap, we introduce a new task, Online Generic Event Boundary Detection (On-GEBD), aiming to detect boundaries of generic events immediately in streaming videos. This task faces unique challenges of identifying subtle, taxonom…

Observables of boundary RG flows from string field theory
We present simple explicit formulae for the change of the $g$-function, boundary state, boundary spectrum and structure constants between the endpoints of short boundary RG flows at next-to-leading order. The formulae are derived using open string field theory and tested on integrable RG flows between conformal boundary states in unitary Virasoro minimal models.

Eine Abfrage der Deutschen #Umwelthilfe zeigt, dass viele Städte trotz gesetzlichem Verbot weiterhin #Gehwegparken dulden.
In Jena bleiben teils nur 50 cm Platz. Das gefährdet besonders Menschen mit #Rollstuhl

Städte dulden illegales Gehwegparken: Abfrage der Deutschen Umwelthilfe zeigt massive Behinderungen für den Fußverkehr
• Nur 33 von 105 Städten bestätigen, dass sie illegales Falschparken auf Gehwegen grundsätzlich nicht dulden• Städte wie Braunschweig, Jena, Paderborn, Wuppertal oder Lübeck gefährden mit Restgehwegbreiten von 50 Zentimetern bis einem Meter Fußgängerinnen und Fußgänger sowie Menschen mit Kinderwagen, Rollator oder Rollstuhl • DUH fordert konsequente Ahndung und sofortiges Abschleppen von illegalen Gehwegparkern und ruft Bürgerinnen und Bürger auf, Falschparker zu melden, die M…

Some rigidity results for static three-manifolds with boundary and positive scalar curvature
This paper studies three-dimensional compact static manifolds with boundary and positive scalar curvature. We prove that, under a suitable bound on the Ricci curvature, the orientable quotient of the Nariai static manifold with boundary $Nar_{-1,1}(\mathbb S^2)$ is the only such manifold with connected boundary, provided that the zero-level set of the potential is connected and does not intersect the boundary. We also establish a rigidity theorem for the upper hemisphere with the standard stati…

3I/ATLAS: Aufnahme zeigt gewachsenen Schweif des interstellaren Kometen
Der dritte bekannte interstellare Komet im Sonnensystem steht jetzt zu nah an der Sonne. Vorher ist noch eine beeindruckende Aufnahme des Schweifs gelungen.
