Multifunktionale DNA‐Moiré‐Supergitter: Moiré‐Strukturen aus den Bausteinen des Lebens

open access: yesPhysik in unserer Zeit, EarlyView.
Moiré‐Strukturen sind längst ein Schlüsselbegriff in der modernen Festkörperphysik. Sie entstehen, wenn sich zwei periodische Materialgitter mit leicht unterschiedlichen Gitterkonstanten oder Orientierungen übereinanderlagern. Das so entstehende großflächige Interferenzmuster, das als Moiré‐Muster bezeichnet wird, kann die physikalischen Eigenschaften ...

Trends and Patterns for the Use of Herbal Medicinal Products for Gynaecological Ailments

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Most Germans consider herbal medicinal products (HMPs) to be an important supplement to conventional medicine. Despite existing clinical evidence for safety and efficacy, they are still not sufficiently integrated into drug therapy of gynaecological complaints in everyday practice.

Elastic properties of highly anisotropic thin poly(propylene) foams

open access: yes, 2004
In this letter, elastic properties of highly anisotropic cellular poly(propylene) films are reported. The material shows peculiar elastic properties compared to other foams in the literature. The data is displayed as the relative Young's modulus $E^*/E_s$

Moisture inversions in the central Arctic: Product assessment and long‐wave radiative effect

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the integrated water vapour and the vertical distribution of water vapour of state‐of‐the‐art reanalyses, weather forecast models, and ground‐ and space‐based remote‐sensing products in the central Arctic. A particular focus lies on the representation of humidity inversions and the quantification of the long‐wave radiative effect ...

A multimodel intercomparison study of variable‐resolution global models with grid refinement over the Arctic and Antarctic

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

Fast Genetic Algorithms

open access: yes, 2017
For genetic algorithms using a bit-string representation of length~$n$, the general recommendation is to take $1/n$ as mutation rate. In this work, we discuss whether this is really justified for multimodal functions. Taking jump functions and the $(1+1)$

Enabling Under Ice Glider Operations: A Backseat Driver Approach

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.
