The method of fuzzy segmentation of a digital image is generalized to the framework of L-fuzzy sets. Such an approach enables the use of various user-defined criteria for comparison of pairs of objects. These criteria are merged into a single mapping whose codomain is a poset. Then a free lattice structures are introduced and the procedure of L-fuzzy(More)
Entecavir (ETV) is one of the most potent agents for the treatment of the hepatitis B viral infection. The drug is principally eliminated by the kidney. The goal of this study was to investigate the potential of ETV to interact in vitro with the renal SLC transporters hOAT1, hOCT2, hCNT2 and hCNT3. Potential drug-drug interactions of ETV at the renal(More)
We define varieties of algebras for an arbitrary endofunctor on a cocomplete category using pairs of natural transformations. This approach is proved to be equivalent to the one of equational classes defined by equation arrows. Free algebras in the varieties are investigated and their existence is proved under the assumptions of accessibility. In universal(More)
