NATO alarmierte deutsche Eurofighter in Rumänien
Wegen russischer Luftangriffe auf die Grenzregion der Ukraine zu Rumänien hat die NATO zwei deutsche Eurofighter alarmiert. Die Kampfflugzeuge starteten, weil sich russische Waffensysteme dem Luftraum Rumäniens näherten, sagte ein Bundeswehrsprecher auf Anfrage der Nachrichtenagentur dpa.
Der Luftraum wurde bei dem Vorfall in der Nacht auf Mittwoch letztlich aber nicht verletz…

Incremental Object Detection with Prompt-based Methods
Visual prompt-based methods have seen growing interest in incremental learning (IL) for image classification. These approaches learn additional embedding vectors while keeping the model frozen, making them efficient to train. However, no prior work has applied such methods to incremental object detection (IOD), leaving their generalizability unclear. In this paper, we analyze three different prompt-based methods under a complex domain-incremental learning setting. We additionally provide a wide…

Möglicherweise Militärdrohne in Polen abgestürzt
Im Osten Polens ist nach Einschätzung der Behörden offenbar eine Militärdrohne in ein Maisfeld gestürzt. In der rund 100 Kilometer südöstlich von Warschau gelegenen Ortschaft Osiny ereignete sich in der Nacht zum Mittwoch eine Explosion, wie die Polizei mitteilte. Opfer gab es demnach nicht, doch in nahe gelegenen Gebäuden wurden Fenster beschädigt. Nach Angaben der Staatsanwal…

Quantum chaos and semiclassical behavior in mushroom billiards I: Spectral statistics
We study the aspects of quantum chaos in mushroom billiards introduced by Bunimovich. This family of billiards classically has the property of mixed phase space with precisely one entirely regular and one fully chaotic (ergodic) component, whose size depends on the width w of the stem, and has two limiting geometries, namely the circle (as the integrable system) and stadium (as the fully chaotic system). Therefore, this one-parameter system is ideal to study the semiclassical behavior of the qu…

The fundamental module of $S_3$-symmetric tridiagonal algebra associated with cycles
Terwilliger recently introduced the $S_3$-symmetric tridiagonal algebra, a generalization of the tridiagonal algebra. This algebra has six generators naturally associated with the vertices of a regular hexagon: adjacent generators satisfy the tridiagonal relations, while non-adjacent ones commute. To each $Q$-polynomial distance-regular graph $Γ$, we associate scalars $β, γ, γ^*, \varrho, \varrho^*$, and define the corresponding $S_3$-symmetric tridiagonal algebra $\mathbb{T} = \mathbb{T}(Î…

Nonlinear stochastic trajectory optimization
Designing robust space trajectories in nonlinear dynamical environments, such as the Earth-Moon circular restricted three-body problem (CR3BP), poses significant challenges due to sensitivity to initial conditions and non-Gaussian uncertainty propagation. This work introduces a novel solver for discrete-time chance-constrained trajectory optimization under uncertainty, referred to as stochastic optimization with differential algebra (SODA). SODA combines differential algebra (DA) with adaptive …

Asymptotic structure. IV. A counterexample to the weak coarse Menger conjecture
Coarse graph theory concerns finding 'coarse' analogues of graph theory theorems, replacing disjointness with being far apart. One of the most interesting open questions is to find a coarse analogue of Menger's theorem, which characterizes when there are $k$ vertex-disjoint paths between two given sets $S,T$ of vertices of a graph. We showed in an earlier paper that the most natural such analogue is false, but a weaker statement remained as a popular open question. Here we show that the weaker …

Multistage Robust Optimization for Time-Decoupled Power Flexibility Aggregation with Energy Storage
To mitigate global climate change, distributed energy resources (DERs), such as distributed generators, flexible loads, and energy storage systems (ESSs), have witnessed rapid growth in power distribution systems. When properly managed, these DERs can provide significant flexibility to power systems, enhancing both reliability and economic efficiency. Due to their relatively small scale, DERs are typically managed by the distribution system operator (DSO), who interacts with the transmission sy…

Permutations satisfying $(P_1)$ and $(P_2)$ properties and $\ell$-optimal bent functions
An important classification of permutations over $\mathbb{F}_2^m$, suitable for constructing Maiorana-McFarland bent functions on $\mathbb{F}_2^m \times \mathbb{F}_2^m$ with the unique $M$-subspace of maximal dimension, was recently considered in Pasalic et al. (IEEE Trans. Inf. Theory 70(6): 4464-4477, 2024). More precisely, two properties called $(P_1)$ and $(P_2)$ were introduced and a generic method of constructing permutations having the property $(P_1)$ was presented, whereas no such resu…
