Polar microcystins or arginine methyl ester can serve as sensitive reference materials for system suitability tests in untargeted metabolomics using reversed-phase LC-MS: A case study Open
Introduction LC-MS system suitability test (SST) is crucial for reliable data acquisition especially in untargeted metabolomics. Objectives Identification of best reference materials (RMs) to improve best quality assurance (QA) and quality…

ECG-based identification of COPD patients at risk for atrial fibrillation and its impact on adverse clinical outcomes—a subgroup analysis of the prospective multicenter COSYCONET cohort Open
Background Atrial fibrillation (AF) frequently occurs in patients with chronic obstructive pulmonary disease (COPD) and is associated with adverse clinical outcomes. We aimed to identify patients at risk for AF using amplified p-wave durat…

Skin Markers of Premature Ageing in Patients with COPD: Results Form COSYCONET Open
Background: Chronic obstructive pulmonary disease (COPD) is commonly associated with ageing, with the prevalence and severity increasing by age. Smoking-induced premature ageing is thought to contribute to COPD, particularly lung emphysema…

Satellite-Based Flood Mapping through Bayesian Inference from a Sentinel-1 SAR Datacube Open
Spaceborne Synthetic Aperture Radar (SAR) are well-established systems for flood mapping, thanks to their high sensitivity towards water surfaces and their independence from daylight and cloud cover. Particularly able is the 2014-launched …

Assessing Vegetation Dynamics Over Mainland Australia With Metop ASCAT Open
Recently, the slope and curvature estimation of the backscatter-incidence angle relationship within the TU Wien retrieval algorithm has been improved. Where previously only climatologies of the slope and curvature parameters were available…
View article: Long-term Soil Moisture Time Series Analyses based on Active Microwave Backscatter Measurements
Long-term Soil Moisture Time Series Analyses based on Active Microwave Backscatter Measurements Open
Active microwave sensors operating at lower microwave frequencies in the range from 1 to 10 GHz provide backscatter measurements that are sensitive to the moisture content of the soil. Thanks to a series of European C-band (5.3 GHz) scatte…
