1. Ultimaten von Donald sind bekanntlich nicht ernst zu nehmen.
2. Welche Hölle möchte man diesen Leuten denn noch versprechen in einem komplett zerstörten Land, wo alle Leute ihr Leben lang nur Krieg kennen? Diese Leute haben wahrscheinlich sowieso schon die meisten Familienmitglieder verloren, welches Leid will man denen denn noch androhen als Feind? Zumal, wenn man nicht mehr in Katar losschlagen darf.

BBB is tegen subsidie voor waterstofproductie als (een gedeelte van) de waterstof wordt geëxporteerd. Mogen we aannemen dat de BBB ook tegen landbouwsubsidie is als (een deel van) de landbouwproductie wordt geëxporteerd?

Mastodon- First-Hinweis: Für das Urbanize-Festival kann ich diesmal gleich zwei Flanerien durchführen:
1) Fr, 17.10 2025, 16:00-18:00 Donaukanal, Anmeldung unter https://urbanize.at/der-donaukanal/

Der Donaukanal
Der Donaukanal und seine Uferanlagen haben eine steile Karriere gemacht: Diente der Wiener Arm der Donau einst der Entsorgung von Unrat und als Rückzugsort randständiger Subjekte, entwickelte er sich zu einem beliebten Freizeitgebiet, dessen konsumfreie Zonen immer wieder durch Investoren-Begehrlichkeiten gefährdet sind. Der Spaziergang mit dem Historiker Anton Tantner widmet sich der Geschichte dieser beliebten urbanen Erholungszone.

Long lifetimes of nanoscale skyrmions in lithium-decorated van der Waals ferromagnet Fe$_3$GeTe$_2$
The Dzyaloshinskii-Moriya interaction (DMI), which originates from spin-orbit coupling and relies on broken inversion symmetry, is recognized as a key ingredient in forming magnetic skyrmions. However, most 2D magnets exhibit inversion symmetry; therefore, the DMI is suppressed. Here, we propose a strategy to induce large DMI via lithium absorption on the surface of 2D magnets -- an experimentally feasible approach. Using first-principles and atomistic spin simulations, we predict the formation…

Lectures on entanglement, von Neumann algebras, and emergence of spacetime
We review recent developments in the use of von Neumann algebras to analyze the entanglement structure of quantum gravity and the emergence of spacetime in the semi-classical limit. Von Neumann algebras provide a natural framework for describing quantum subsystems when standard tensor factorizations are unavailable, capturing both kinematic and dynamical aspects of entanglement. The first part of the review introduces the fundamentals of von Neumann algebras, including their classification, a…

Mir nötig die Entscheidung von Bundeskanzler #Merz einigen Respekt ab, sich gegen weitere Waffenlieferungen auszusprechen, die im Krieg gegen Gaza eingesetzt werden können. Schließlich hat er sich dabei auch gegen Stimmen der eigenen Fraktion gestellt.
Allerdings habe ich noch keinen Hinweis gefunden, welche konkreten Waffen nun nicht geliefert werden.
Mir erscheint es weitgehend ein Tr…

Emergent Ising symmetry and supercritical fluids
The symmetry of Ising model questions any single crossover scenario for supercritical fluids. In this work, we firstly study a pair of thermodynamic crossovers $L^\pm$ analytically for the Van der Waals class fluids. We uncover an emergent $Z_2$ symmetry in addition to the universal scalings in the scaling regime for this class fluids. By using the self-reciprocal property between coexistenct phases, we further establish that under suitable conditions, the Ising symmetry generally emerges in th…

s-process Enriched Post-AGB Star J003643.94-723722.1 in the SMC with an Extreme C/O Ratio and the First Precise Detection of Lead
Post-asymptotic giant branch (post-AGB) stars are exquisite tracers of s-process nucleosynthesis via their surface abundances. We present a comprehensive analysis of J003643.94$-$723722.1 (J003643), a single SMC post-AGB star, using high-resolution UVES/VLT spectra analysed with E-iSpec. We find C/O = 16.21 and $[\mathrm{s}/\mathrm{Fe}]=2.09\pm0.20 \mathrm{dex}$. We also report the first direct Pb detection in a post-AGB star from the Pb II 5608.853 A line, with $[\mathrm{Pb}/\mathrm{Fe}]=3.18\…

Ultrathin oxide freestanding membranes with large-scale continuity and structural perfection
Freestanding oxide membranes offer integration with advanced semiconductor platforms, unlocking opportunities for flexible electronics, silicon-based spintronics, neuromorphic computing, and high-performance energy technologies. Scalable fabrication of such membranes is essential for bridging fundamental discoveries in complex oxides with practical device deployment. However, the lateral dimensions of crack- and wrinkle-free membranes remain limited to millimeter scales, forming a critical bott…

Ta2Pd3Te8: A potential candidate of 1D van der Waals stacked thermoelectric materials
Discovering new thermoelectric (TE) materials is an eternal goal in the TE field. Excellent TE materials have ranged from 3D stacked to 2D stacked bulk. However, the 1D stacked receives little attention due to the scarcity in quantity. In this work, it is predicted that 1D van der Waals (vdW) stacked Ta2Pd3Te8 crystal is a compelling candidate for TE applications by combining first-principles calculations with phonon and electron Boltzmann transport equations and molecular dynamics methods.
