Diagnostic processes of Alzheimer's disease (AD) are evolving. Knowledge about disease-specific biomarkers is constantly increasing and larger volumes of data are being measured from patients. To gain additional benefits from the collected data, a novel statistical modeling and data visualization system is proposed for supporting clinical diagnosis of AD.(More)

Algal lipids provide essential fatty acids for higher trophic levels in the marine food web, and understanding the fatty acid composition in phytoplankton is critical for evaluating its value as a diet. Nineteen microalgal species, mainly originating from the Baltic Sea, covering major algal classes were grown in different growth conditions. Samples were(More)
Medical research and clinical practice are currently being redefined by the constantly increasing amounts of multiscale patient data. New methods are needed to translate them into knowledge that is applicable in healthcare. Multiscale modeling has emerged as a way to describe systems that are the source of experimental data. Usually, a multiscale model is(More)
OBJECTIVE To systematically investigate whether overnight features in transcutaneous carbon dioxide (P(TcCO(2)) measurements can predict metabolic variables in subject with suspected sleep-disordered breathing. METHODS The features extracted from the P(TcCO(2)) signal included the number of abrupt descents per hour and attributes that characterize the(More)
