The aim of this study was to evaluate the accuracy of artificial intelligence based plant image identification applications among the Estonian Flora. Automated identification is relatively new and has not been examined using an extensive dataset. Two applications, Pl@ntNet and Flora Incognita, were used to identify 1501 images from a national database (551 taxa) and 1000 observations from field conditions...

Word embeddings are an influential machine learning framework in natural language processing that represents each word in a large text body with a vector. Geometric relationships between the vector representations capture meaningful semantic relationships between the corresponding words. The research paper “Gender stereotypes in Estonian word embeddings” emulated experiments of earlier English literature on the subject, but in the context...

Non-conventional yeasts and their enzymes are scarcely studied but they could have unique characteristics with biotechnological applications which are uncommon for enzymes of bakers’ yeast. α-Glycosidases are enzymes which hydrolyze sugars, but some of them synthesize short saccharides. The aim of the study was to characterize the activities and biochemical parameters of α-glucosidase AG2 (BaAG2) from evolutionally old yeast Blastobotrys...

Persistent cytomegalovirus (CMV) infection is one of the drivers of immunological ageing, which impairs the immune function of elderly people. In this study we show that higher anti-CMV antibody levels are associated with several chronic diseases in old individuals. We found that people diagnosed with either type 2 diabetes, chronic kidney disease or disorders of the thyroid gland had significantly...

Metal-air batteries, such as Al-air, Zn-air, Mg-air are a novel green energy storage devices, which overcome the limitations of hydrogen technology and Li-ion batteries in replacing fossil fuels. Using mainly chronopotentiometry and impedance spectroscopy techniques in a three-electrode system, the emphasis was on testing 171 cathode prototypes to develop a state-of-art cathode. The developed cathodes were used in a full-sized...
