Wenn Männer mit der Mentalität von Fünfjährigen anderen die Mentalität von Elfjährigen vorwerfen -
ist das in erster Linie eine Beleidigung für alle Fünf- und Elfjährigen.

The overflow in the Katona Theorem
Let $n>2r>0$ be integers. We consider families $\mathcal{F}$ of subsets of an $n$-element set, in which the union of any two members has size at most $2r$. One of our results states that for $n\geq 6r$ the number of members of size exceeding $r$ in $\mathcal{F}$ is at most $\binom{n-2}{r-1}$. Another result shows that for $n>3.5r$ the number of sets of size at least $r$ is at most $\binom{n}{r}$. Both bounds are best possible and the latter sharpens the classical Katona Theorem. Similar results…

Survival of dust in super-dusty galaxies at redshifts $z \approx 5-8$
The presence of dust in galaxies at redshifts $z>5$ is commonly connected with core collapse supernovae (SN). Galaxies with exceptionally large dust mass, of order of $1 - 3$\% of the galaxy stellar mass, have been detected during the last decade. The required SN dust yield is $\gtrsim 1~M_\odot$ per supernova, which is comparable to the theoretically predicted maximum. However, the reverse shock (RS) penetrating the SN ejecta significantly destroy the dust particles nucleating there through sp…

#ndwgoecountdown Meteoriten – Boten aus dem All
Immer wieder bahnen sich Gesteinsbrocken aus dem Weltall ihren Weg auf die Erde. Meteoriten sind interessant für Forschende. Denn die Brocken sind Zeitzeugen der Entstehung des Sonnensystems. Ihre genaue Zusammensetzung kann helfen zu verstehen, wie das Sonnensystem zu dem Ort wurde, den wir heute kennen. Mit echten Meteoriten zu…

The ILD Detector: A Versatile Detector for an Electron-Positron Collider at Energies up to 1 TeV
The International Large Detector, ILD, is a detector concept for an experiment at a future high energy lepton collider. The detector has been optimised for precision physics in a range of energies from 90~GeV to about 1~TeV. ILD features a high precision, large volume combined silicon and gaseous tracking system, together with a high granularity calorimeter, all inside a central solenoidal magnetic field. The paradigm of particle flow has been the guiding principle of the design of ILD. ILD is …

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…
