Neue Schleswig-Holstein-Schiene: Die Ausgabe 48 des Magazin des Fahrgastverbands PRO BAHN für Bahn, Bus und Fähre in Schleswig-Holstein, Hamburg und Nordostniedersachsen widmet sich vor allem der Infrastruktur. Die einzelnen Artikel behandeln Themen wie Auswirkungen einer Stilllegung der Bäderbahn, Durchbindung von im Hamburger Hbf endenden Nachtzüge, die nicht genutzte Bahnstrecke Niebüll – Flensburg oder die Weiterentwicklung des Schleswig-Holstein-Tarifs.

The Reservoir of the Per-emb-2 Streamer
Streamers bring gas from outer regions to protostellar systems and could change the chemical composition around protostars and protoplanetary disks. We have carried out mapping observations of carbon-chain species (HC$_3$N, HC$_5$N, CCH, and CCS) in the 3mm and 7mm bands toward the streamer flowing to the Class 0 young stellar object (YSO) Per-emb-2 with the Nobeyama 45m radio telescope. A region with a diameter of $\sim0.04$ pc is located north with a distance of $\sim 20,500$ au from the YSO.…

Evaluating Datalog over Semirings: A Grounding-based Approach
Datalog is a powerful yet elegant language that allows expressing recursive computation. Although Datalog evaluation has been extensively studied in the literature, so far, only loose upper bounds are known on how fast a Datalog program can be evaluated. In this work, we ask the following question: given a Datalog program over a naturally-ordered semiring $σ$, what is the tightest possible runtime? To this end, our main contribution is a general two-phase framework for analyzing the data compl…
