The measurement of the integrated luminosity delivered to the CMS experiment is calibrated with a dedicated series of scans under special run conditions. With Van der Meer (VdM) scans, the transverse size of the overlap of the two proton beams can be measured, allowing for a calibration of the absolute luminosity scale. [...]

Die DESY Bibliothek ist an den beiden Standorten Hamburg und Zeuthen für die umfassende und hochwertige Literatur- und Informationsversorgung der Mitarbeiterinnen und Mitarbeiter des Deutschen Elektronen-Synchrotrons DESY sowie darüber hinaus von jährlich mehr als 3000 Gastwissenschaftlerinnen und -wissenschaftlern aus über 40 Nationen verantwortlich. Ihr Dienstleistungsportfolio umfasst ferner den Eigenverlag, Dienstleistungen rund um das wissenschaftliche Publizieren und die maßgebliche Partnerschaft an der Hochenergiephysikdatenbank INSPIRE.Gerade für eine kleine Bibliothek stellen derartige Anforderungen eine Herausforderung auch an die Geschäftsgänge dar.

Biodegradable magnesium-alloys are promising implants in orthopedic and cranio-facial surgery to form osteofixation devices that slowly degrade into biocompatible products and do not require a second intervention for removal. However, their degradation needs to be tailored to match the regeneration ability of the bone. [...]

We systematically study the enhancement of soft-X-ray high-harmonic generation in Ar, reaching a factor as high as ~8, at different pressures driven by two-color (ω+3ω) mid-infrared waveforms and compare the results to full 3D simulations..

One of the key issues for generation of stable and reproducible beams in plasma particle accelerators is control of the initial plasma density distribution. Not only the longitudinal but also the transverse density profile, the species distribution as well as fragmentation and ionisation dynamics can have significant impact on the generated beams [...]

Pulmonary surfactant forms the alveolar monolayer at the air/aqueous interface within the lung. During the breathing process, the surface pressure periodically varies from ~40mN/m up to ~70mN/m. [...]

Abstract In this study fatigue and tensile test specimens were produced by Metal Injection Moulding (MIM) using gas atomised Ti-6Al-4V-powder with addition of 0.5 wt.% yttrium powder as well as pure Ti 6Al 4V powder as reference. The addition of yttrium resulted in a noticeably refinement of the grain size from 150 µm to 50 µm by formation of Y2O3 particles hindering grain growth. [...]
