Gouverneur spricht von "massivem Luftangriff" der Ukraine
Der Rostower Gouverneur Sljusar schrieb im Onlinedienst Telegram von einem "massiven Luftangriff", den das russische Militär abgewehrt habe. Das russische Verteidigungsministerium schrieb von insgesamt 112 ukrainischen Drohnen, die die Luftabwehr binnen neun Stunden über dem eigenen Staatsgebiet abgefangen habe. 34 davon habe es alleine oberhalb der Region Rostow zerst…

Benamou-Brenier and Kantorovich are equivalent on sub-Riemannian manifolds with no abnormal geodesics
We prove that the Benamou-Brenier formulation of the Optimal Transport problem and the Kantorovich formulation are equivalent on a sub-Riemannian connected and complete manifold $M$ without boundary and with no abnormal geodesics, when the problems are considered between two measures of compact supports. Furthermore, we prove the existence of a minimizer for the Benamou-Brenier formulation and link it to the optimal transport plan.

Detection of CO$_2$, CO, and H$_2$O in the atmosphere of the warm sub-Saturn HAT-P-12b
The chemical composition of warm gas giant exoplanet atmospheres (with Teq < 1000 K) is not well known due to the lack of observational constraints. HAT-P-12 b is a warm, sub-Saturn-mass transiting exoplanet that is ideal for transmission spectroscopy. One transit of HAT-P-12 b was observed with JWST NIRSpec in the 2.87-5.10 $μ$m range with a resolving power of $\sim$1000. The JWST data are combined with archival observations from HST WFC3 covering the 1.1-1.7 $μ$m range. The data are analyse…

Investigating silicate, carbon, and water in the diffuse interstellar medium: the first shots from WISCI
The dusty interstellar medium (ISM) of the Milky Way is distributed in a complex, cloudy structure. It is fundamental to the radiation balance within the Milky Way, provides a reaction surface to form complex molecules, and is the feedstock for future generations of stars and planets. The life cycle of interstellar dust is not completely understood, and neither are its structure nor composition. The abundance, composition, and structure of dust in the diffuse ISM can be determined by combining …

playing prague | Prague City Tourism
Playing Prague is a game celebrating Prague and all those who have shaped and continue to shape this beautiful city. Every detail of the game is a tribute to the 1000-year cultural heritage of a city that was once the seat of the Holy Roman Emperors and the capital of the Bohemian Kingdom. It is also the origin of the designation of bohemians as people with a creative and unconventional way of life. Become a Bohemian for a while and build your own Prague.

Vector valued weighted analogue of converse of Wiener-L\'evy theorem and applications to modulation spaces

Vector valued weighted analogue of converse of Wiener-Lévy theorem and applications to modulation spaces
We shall prove a strong converse of the Wiener-Lévy theorem in weighted setting for Banach algebra valued functions. In fact, it is shown that if $ω$ is a weight on a discrete abelian group $G$, $\mathcal X$ is a unital commutative Banach algebra and if $F$ is a $\mathcal X-$valued function defined on $\mathbb C$ such that $T_F(f)=F\circ f \in A^q(Γ,\mathcal X)$ for all $f\in A^1_ω(Γ,\mathcal X)$, then $F$ must be real analytic. Its multivariate analogue and analogue for locally compact ab…

Enhanced Superconductivity and Vortex Dynamics in One-Dimensional TaS2 Nanowires
We report the synthesis of high-quality 2H-TaS2 nanowires via a controlled two-step conversion process from TaS3 precursors, achieving robust superconductivity with a transition temperature Tc ~ 3.6 K which is significantly higher than bulk 2H-TaS2 (Tc ~ 0.8 K). Structural and compositional analyses confirm phase purity and preserved 1D morphology, while magnetotransport measurements reveal an enhanced upper critical field μoHc2 (2 K) ~ 5 T, far exceeding the bulk value (μoHc2 (0) ~ 1.17 T), …

🤔 Interestingly enough I've talked a lot about Niri today, even adjusted the config, but ended up spending time in Project Banana, the immutable KDE Linux (by KDE, based on Arch). And Calculate Linux, a Russian Gentoo spin.

A construction that preserves the configuration of a matroid, with applications to lattice path matroids
The configuration of a matroid $M$ is the abstract lattice of cyclic flats (flats that are unions of circuits) where we record the size and rank of each cyclic flat, but not the set. One can compute the Tutte polynomial of $M$, and stronger invariants (notably, the $\mathcal{G}$-invariant), from the configuration. Given a matroid $M$ in which certain pairs of cyclic flats are non-modular, we show how to produce a matroid that is not isomorphic to $M$ but has the same configuration as $M$. We sh…
