AKW Gundremmingen: Termin für die Sprengung der Kühltürme steht
Auf Nachfrage der Redaktion bestätigt der Betreiber RWE jetzt offiziell: Am Samstag, 25. Oktober, fallen die Kühltürme. Auf Gundremmingen wird einiges zukommen.

Trump maintains control over and can profit from his businesses while in office through a revocable trust, of which he is both the sole donor and sole beneficiary.
In his first term, those looking to support Trump financially could lend him money against his real estate, license his name, buy his assets, join one of his clubs or book a hotel.
Since leaving office in 2021, Trump’s business empire expanded into the digital realm, where the products are often intangible, but the rev…

A direct approach to tree-guided feature aggregation for high-dimensional regression
In high-dimensional linear models, sparsity is often exploited to reduce variability and achieve parsimony. Equi-sparsity, where one assumes that predictors can be aggregated into groups sharing the same effects, is an alternative parsimonious structure that can be more suitable in certain applications. Previous work has clearly demonstrated the benefits of exploiting equi-sparsity in the presence of ``rare features'' (Yan and Bien 2021). In this work, we propose a new tree-guided regularizatio…

A note on Wang's conjecture for harmonic functions with nonlinear boundary condition
We obtain some Liouville type theorems for positive harmonic functions on compact Riemannian manifolds with nonnegative Ricci curvature and strictly convex boundary and partially verifies Wang's conjecture (J. Geom. Anal. 31 (2021)). For the specific manifold $\mathbb{B}^n$, we present a new proof of this conjecture, which has been resolved by Gu-Li (Math. Ann. 391 (2025)). Our proof is based on a general principle of applying the P-function method to such uniqueness results. As a further app…

Slomads Rising: Stay Length Shifts in Digital Nomad Travel, United States 2019-2024
Using every U.S. Airbnb reservation created from 1 January 2019 through 31 December 2024, weighted by nights booked, we document a lasting shift toward longer stays after the COVID 19 shock. Mean nights per booking rose from 3.7 before the pandemic to a stable 4.1 to 4.4 after 2021; the median increased from two to three nights and the weighted standard deviation nearly doubled to seven nights, indicating a heavier tail. Negative binomial regression shows that, relative to the restriction perio…

Timing and spectral variability in 2S 1417-624 observed with Insight-HXMT
We present the results of the spectral and timing analyses of the accreting X-ray pulsar, 2S 1417-624, during the 2018 and 2021 outbursts with Insight-HXMT. We find that the pulse profiles in all energy bands exhibit clear double-peaked structures at low flux states. In the 1-10 keV band, the pulse profiles evolve from double to triple peaks at a flux level of $\sim$4.1$\ \times \ 10^{-9}$ erg cm$^{-2}$ s$^{-1}$, and from triple to quadruple peaks at $\sim$6.4$\ \times \ 10^{-9}$ erg cm$^{-2}$ …

A multi-frequency global view of Callisto's thermal properties from ALMA
We present thermal observations of Callisto's leading and trailing hemispheres obtained using the Atacama Large Millimeter/submillimeter Array (ALMA) at 0.87 mm (343 GHz), 1.3 mm (233 GHz), and 3 mm (97 GHz). The angular resolution achieved for these observations ranged from 0.09-0.24 arcseconds, corresponding to ~420-1100 km at Callisto. Global surface properties were derived from the observations using a thermophysical model (de Kleer et al. 2021) constrained by spacecraft data. We find that …
