Bastelprojekt: 3D-gedruckte VTOL-Drohne fliegt knapp 210 km mit einer Ladung
Ohne große Kenntnisse über Aerodynamik und CAD entwickelte ein Bastler eine VTOL-Drohne mit hoher Reichweite. Die meisten Bauteile stammen aus dem 3D-Drucker.

Magnetosonic Waves as a Driver of Observed Temperature Fluctuation Patterns in AGN Accretion Disks
Recent observations have revealed slow, coherent temperature fluctuations in AGN disks that propagate both inward and outward at velocities of $\sim 0.01 - 0.1c$, a kind of variability that is distinct from reverberation (mediated by the reprocessing of light) between different regions of the disk. We investigate the origin and nature of these fluctuations using global 3D radiation-magnetohydrodynamic simulations of radiation and magnetic pressure-dominated AGN accretion disks. Disks with a sig…

Robustness of Floquet topological phase at room temperature: a first-principles dynamics study
Nonadiabatic Thouless pumping of electrons is studied within the framework of topological Floquet engineering, particularly focused on how atomic lattice dynamics affect the emergent Floquet topological phase in trans-polyacetylene under the driving electric field. As similarly done in the earlier work [Zhou and Kanai, J. Phys. Chem. Lett., 12, 4496 (2021)], the real-time time-dependent density functional theory and Ehrenfest dynamics simulations were used to investigate the extent to which the…

Haha, this was a rather fundamental misunderstanding (or more like brain glitch) of moment of inertia in Microsoft Flight Simulator, and only now they are fixing it. Well, better late than never. https://devsupport.flightsimulator.com/t/payload-moments-of-…

It’s especially frustrating because there •is• election manipulation happening in plain sight: voter suppression, gerrymandering, a vast media empire of right-wing falsehood, microtargeted disinformation from billionaires and hostile foreign states alike, GOP- and Putin-backed grifters posing as left-leaning third party candidates and then just pocketing the donations and disappearing —
•none• of that even in doubt. We do not need to search for a shadowy conspiracy. Democracy’s being strangled in broad daylight.

Approach to network failure due to intrinsic fluctuations
A networked system can fail when most of its components are unable to support flux through the nodes and edges. As studied earlier this scenario can be triggered by an external perturbation such as an intentional attack on nodes or for internal reasons such as due to malfunction of nodes. In either case, the asymptotic failure of the network is preceded by a cascade of nodal failures. In this work, we focus on the nodal failure arising from the intrinsic fluctuations in the flux passing through…
