... aqueous conditions, deviations from the allowed regions of the Ramachandran plot are greater than observed under the other two conditions, suggesting the incomplete formation of an a-helical structure. ... agents can report the positioning of individual residues, and on the orientation of the whole helix relat- ive to the micellar core. The effects of these age...

... expansion invokes another use of the same rule. When this happens, we do not count the distance between the first and second expansion. However, the second expansion is still remembered as the ... for both the non-randomized and random- ized treebanks. The distance between two occur- rences of a rule is calculated as the number of words between the first word on the...

... resource depends on the performance of its rule applications rather than on the proportion of correct rules it contains. A rule, whether correct or incorrect, has insignificant ef- fect on the resource’s ... validation is the “logical context”. The logical context de- termines the monotonicity of the LHS and is in- duced by logical operators such as negation and (expl...

... composition, we completed additional MS and NMR-based analysis of the cRBC glycan pool. In addition to identification and quantification of other monosaccharides, we aimed to characterize the overall sialic ... pool, we detect the presence of several important signatures, including the H-1 anomeric protons, the H-2 protons of man- nose (Man) (d 4.05–4.25 p.p.m.), and the met...
