If the graph is labelled, we can write the label of each edge into its cell; if it is unlabelled, we can mark the edges with any symbol we choose. Although graphs are useful for tutorial purposes, the graphs of
However, the T g values of the labelled PS samples are higher than the unlabelled ones with the difference widening as M n decreases. This difference is explained by a decrease of chain end mobility and hence of free volume caused by bulky end groups....
1 Introduction Machine learning falls into two broad categories: supervised learning and unsu- pervised learning, primarily distinguished by the use of labelled and unlabelled data. Semi-supervised learning has received considerable attention in the litera- ture due to its potential in reducing the ...
particularly since medical expertise is required to label the data, which may be very costly and time consuming. Instead, it is often the case that there exists a large corpus of unlabelled data and a smaller set of labelled data.
The structure and mass of unlabelled Z-OMPD and 13C-labelled [1,5 13C2]Z-OMPD were confirmed by 1H-NMR spectroscopy and mass spectrometry (Fig. S2), respectively. pH sensitivity To evaluate the pH sensitivity of the 13C-labelled carboxylic acid carbons, a titration series of thermal 13C...
NMR spectra with unlabelled and fully 13C-labelled, highly concentrated pyruvic acid revealed the presence of three chemical impurities of pyruvic acid, and we identified the pH-sensitive molecule as ZA, based on its 1H and 13C chemical shifts and coupling constants (Supplementary Figs 2 and 3)...
Glucose and glutamine are the two dominant metabolic substrates in cancer cells. In 13C tracer experiments, however, it is necessary to account for all significant input substrates, as some natural (unlabelled) substrate in the medium, often derived from
In the unlabelled setting, the flip graph is known to be isomorphic to the 1-skeleton of a polyhedron, called the associahedron. Araujo-Pardo et al. proved that this is also the case for the edge-labelled setting, and called the resulting polyhedron the colourful associahedron. As part of...
Further development of standard laboratory simulation rigs, for use with both labelled and unlabelled compounds, in other emerging sewage treatment processes, would also allow for a controlled comparison of the performance of the technologies and inform the best process selection to address the growing ...
FIG. 4 illustrates an example of indicator-dilution curve outflow profiles in the canine pulmonary circulation in control conditions (A) and after injection of unlabelled rAM(1-50) (B), Insets showing the natural log ratio curves of the tracers (FR is fractional recovery of each tracer); FI...
