... machine learning-based approaches to antecedent identification can be classified as ei- ther the candidate-wise classification approach or the preference-based approach. In the former ap- proach ... anaphor indirectly as a by-product of the search for its antecedent. If an appropriate candidate antecedent is found, the anaphor is classified as anaphoric; otherwise, it is classified as no...

... the outer cell wall a number of sophisticated channels called porins. One of them, maltoporin, is a passive specific channel for the maltodextrin uptake. This channel was also named LamB as the ... outer cell wall. Under stress, e.g. in case of lack of nutrition, the pure diffusion process is too slow and the bacteria need to improve the efficiency of the translocation. For those ca...

Cell number was calculated by counting the number of tricomes (each cell has a single tricome) for the selected area of each compartment, shaded in orange for the A compartment and in azure for ... apoptotic cells. As is evident, Cas3 staining revealed large areas of apoptotic cells localized in the V (unsilenced) compart- ment. These apoptotic foci were composed of GFP-labelled d...
