On the use of tabulated equations of state for multi-phase simulations in the homogeneous equilibrium limit
The use of complex multi-parameter equations of state in computational fluid dynamics is limited due to their expensive evaluation. Tabulation methods help to overcome this limitation. We propose in this work ...

A gastrointestinal stromal tumour mimicking solid pseudopapillary neoplasia of the pancreas—a case report
Diagnosis of large, heterogenous lesions of the pancreas with solid and cystic components is often challenging. The spectrum of differential diagnoses is broad, and clinical as well as radiological findings ma...

Potential modes of range shifts in euryhaline snails from the Baltic Sea and fresh water lakes in northern Germany
The widely distributed snail species Theodoxus fluviatilis (Linneaus, 1758) is rather diverse in shell size and patterning. It has formed regional subgroups in northern Germany that appear separate in either fres...

A non-noble Cr-Ni-based catalyst for the oxygen reduction reaction in alkaline polymer electrolyte fuel cells
We report on a new type of polymer electrolyte fuel cell based on a hydroxide ion conductive polymer combined with a non-noble chromium–nickel (Cr–Ni) catalyst for the oxygen reduction reaction (ORR). We study...

Prediction of Aromatic Hydroxylation Sites for Human CYP1A2 Substrates Using Condensed Graph of Reactions
In this paper, support vector machine and condensed graph of reaction (CGR) approaches have been used to predict the regioselectivity of aromatic hydroxylation for human CYP1A2 substrates. Experimental data on...

Directionality of non-permissive HLA-DPB1 T-cell epitope group mismatches does not improve clinical risk stratification in 8/8 matched unrelated donor hematopoietic cell transplantation
In 8/8 HLA-matched unrelated donor (UD) hematopoietic cell transplants (HCT), HLA-DPB1 mismatches between alleles from different T-cell epitope (TCE) groups (non-permissive mismatches) are associated with sign...

Open AccessMagnetisation switching of FePt nanoparticle recording medium by femtosecond laser pulses
Manipulation of magnetisation with ultrashort laser pulses is promising for information storage device applications. The dynamics of the magnetisation response depends on the energy transfer from the photons t...

Determination of Pesticides Adsorbed on Arthropods and Gastropods by a Micro-QuEChERS Approach and GC–MS/MS
A miniaturized QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Save) approach combined with gas chromatography–tandem mass spectrometry (GC–MS/MS) has been developed for the simultaneous determination of ...

Cross‐scale intercomparison of climate change impacts simulated by regional and global hydrological models in eleven large river basins
Ideally, the results from models operating at different scales should agree in trend direction and magnitude of impacts under climate change. However, this implies that the sensitivity to climate variability a...

Open AccessLiquid-state carbon-13 hyperpolarization generated in an MRI system for fast imaging
Hyperpolarized (HP) tracers dramatically increase the sensitivity of magnetic resonance imaging (MRI) to monitor metabolism non-invasively and in vivo. Their production, however, requires an extra polarizing devi...

Reduced CO2 fertilization effect in temperate C3 grasslands under more extreme weather conditions
A temperate grassland experiment shows that CO2 fertilization increases above-ground biomass most strongly under local average environmental conditions, but the effect is reduced or disappears under wetter, drier...

Open AccessStacked search for time shifted high energy neutrinos from gamma ray bursts with the Antares neutrino telescope
A search for high-energy neutrino emission correlated with gamma-ray bursts outside the electromagnetic prompt-emission time window is presented. Using a stacking approach of the time delays between reported g...

Open AccessEarly Endothelial Progenitor Cells (eEPCs) in systemic sclerosis (SSc) - dynamics of cellular regeneration and mesenchymal transdifferentiation
Patients with systemic sclerosis (SSc) are endagered by tissue fibrosis and by microvasculopathy, with the latter caused by endothelial cell expansion/proliferation. SSc-associated fibrosis potentially results...
