Prof. Ulrich Walter, Mainz In this issue of Hämostaseologie five case reports are published (1–5) besides an interdisciplinary guideline (S2K-Leitlinie der ständigen Kommission Pädiatrie der Gesellschaft für Thromboseund Hämostaseforschung) (6), a review concerning von Willebrand disease and TTP (7) and an original paper comparing the computerized dosage of phenprocoumon with the physician guid...

Stars originate from the dense interstellar medium, which exhibits filamentary structure to scales of $\sim 1$ kpc in galaxies like our Milky Way. We explore quantitatively how much resulting large-scale correlation there is among different stellar clusters and associations \emph{orbit phase space}, characterized here by actions angles. As a starting point, we identified 55 prominent overdensit...

We show that a granular suspension, composed of particles immersed in a liquid, can form pearls, hooks, and arches when deposited from a nozzle onto a translating substrate that acts as a liquid super-absorber. The removal of the liquid induces a rapid pinning of the contact line leading to mechanically stable structures that are held together by capillary adhesion with shapes that depend on th...

This paper introduces a novel segmentation technique, called pearling, for identifying tubular structures in images. Examples of such structures include, but are not limited to, blood vessels, bones, roads, rivers, electrical wirings, and brush-strokes. Pearling allows the user to extract a higher level parametric representation of each tube or of a network of tubes. This representation is comp...

Pearls and Pitfalls in Head and Neck Surgery Introduction An SND consists of the en bloc removal of the lymph node groups that are most likely to harbor metastases depending upon the location of the primary tumor. The goal of such an operation is to remove the nodes at risk while preserving function and minimizing morbidity. A selective dissection of the nodes of levels I, II, and III/IV (supra...
