Cross-age tutors were randomly assigned to one of the three tutor training conditions distinguished for the current study: (1) the labelling experimental condition, characterized by requirements to label their tutor interventions, based on the e-moderating model of Salmon; (2) the non-labelling experimental condition, focusing on tutor’s acting upon the role of an e-moderator without preliminar...

Growing neural gas (GNG) has been successfully applied to unsupervised learning problems. However, GNG-inspired approaches can also be applied to classification problems, provided they are extended with an appropriate labelling function. Most approaches along these lines have so far relied on strategies which label neurons a posteriori, after the training has been completed. As a consequence, s...

BACKGROUND NRD convertase, also termed Nardilysin, is a Zn(++) metalloendopeptidase that specifically cleaves the N-terminus of arginine and lysine residues into dibasic moieties. Although this enzyme was found located within the testis, its function in male reproduction is largely unknown. In addition, the precise distribution of this enzyme within germ cells remains to be determined. METHOD...

An efficient 11C-labelling method, using [11C]CH3Li for the labelling of a variety PET-tracers via cross-coupling reaction is presented.

Given a 3-uniform hypergraph H consisting of set V vertices, and T?V3 triples, null labelling is an assignment ±1 to the triples such that each vertex contained in equal number labelled +1 ?1. Thus, signed degree zero. A necessary condition for every even. The Null Labelling Problem determine whether has labelling. It proved this problem NP-complete. Computer enumerations suggest most hypergrap...

We give a method of proving termination of Klop’s higher-order rewriting format, combinatory reduction system (CRS). Our method called higher-order semantic labelling is an extension of Zantema’s semantic labelling for first-order term rewriting systems. We systematically define the labelling by using the complete algebraic semantics of CRS.

Nowadays, three dimensional (3D) cell cultures are widely used in the biological laboratories and several optical clearing approaches have been proposed to visualize individual cells deepest layers of cancer multicellular spheroids. However, defining most appropriate approach for different lines is an open issue due lack a gold standard quantitative metric. In this article, we describe share si...

Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...

Various 13CO� labelling approaches exist to trace carbon (C) dynamics in plant-soil systems. However, it is not clear if the different approaches yield the same results. Moreover, there is no consistent way of data analysis to date. In this study we compare with the same experimental setup the two main techniques: pulse and continuous labelling. We evaluate how these techniques perform to estim...

BACKGROUND beta-III-neurotubulin is a characteristic degradation protein of cellular cytoskeleton of nervous tissues, which originates with disorders that lead to the loss of peripheral neurons or neurons of the central nervous system. For the diagnostics of neuropathic and neurodegenerative processes, beta-III-neurotubulin is therefore the goal structure, and radioactive labelled antibody TU-2...
