Labels functions

In this chapter we will review the recent investigations of the structure of both the a and P subunit, and the function of gastric H,K-ATPase. We will proceed from a brief overview of the tissue distribution to a successive discussion of structure, kinetics, transport properties, lipid dependency, solubilization and reconstitution, and inhibitors of H,K-ATPase that may label functionally important domains of the enzyme. 

Analysis of hydrocarbons from anal fluids (feces) involved in nest marking by the ant Messor capitatus (Grasso et al., 2005) suggests that territory marking using abdominal secretions issued from the rectal sac may be another labeling function by the way of abdominal secretions. The same authors reported that the hydrocarbons in the feces were similar to those hydrocarbons on the cuticle of workers.

MS-based ee-screening of isotopically labeled substrates [50]. a) Asymmetric transformation of a mixture of pseudo-enantiomers involving cleavage of the functional groups FG and labeled functional groups FG. b) Asymmetric transformation of a mixture of pseudo-enantiomers involving either cleavage or bond formation at the functional group FG isotopic labeling at R2...

Are the helical movements detected by the spin labels functionally important If so, a molecular cross-link between the helix in question and an adjacent helix that does not move or moves in a different direction should block activation of transducin. To implement this strategy to identify functionally relevant helix motions, two different kinds of interhelical cross-links have been employed. In the first, helices are cross-linked by spontaneous or catalyzed disulfide formation between two cysteines, one engineered in each helix. In the second, cross-links are introduced by binding of Zn2+ to engineered histidine ligands, one in each helix (Elling et al., 1995). 

A hypergraph H = (V,E) is labeled if there exists labeling functions defined on the set of vertices V and on the set of edges E, which establish a correspondence between each vertex and each edge and some label. Let A V) = a(ui),...,a(up) and A E) = a Ei),..., a Eq) be the sets of possible labels called vertex and edge alphabets. The sets A V) and A E) may be represented by symbolic, numerical and structural labels. 

Activist/Consumer Like the behavioral scientist, the activist approaches the label as a device for increasing the amount of information available to the consumer or worker. The underlying assumption is that information is inherently valuable, and more information is always in the public interest. The consumer/labor advocate wishes to label in the interest of information transfer to the user or worker, so as to enhance the right to know. The reader may find it useful to review a related perspective on labeling functions and orientations provided in the Bambury Report 6 entitled Product Labeling and Health Risks edited by Morris et al. (1980)... 

A total synthesis of (15S)-HETE uses a Wittig reaction of the ylide (184) to construct the eicosane skeleton (185). Examples of the use of both phosphonate- and ylide-based olefination in prostaglandin chemistry include the synthesis of the stable prostacyclin analogues (186) containing an azidophenyl group as a photoaffinity labelling functionality. ... 

L 5 -> 2 is a labeling function. L is injective and associates with each state a set of boolean propositions true in the state.

Additionally, a labeling function of this matrix allowed the analyses of oligosaccharides on attomole level (see section 3.5) (Kaneshiro, K. et al., 2011). 

Most DSI ions have been postulated in a purely empirical way. However, the composition of some ions, which are not commonly observed species, has not been elucidated thus far. Further investigation of the SI ions of compounds with labeled functional groups is a plausible approach to this problem. There is no doubt that SIOMS with the labeling technique should provide a unique method for studying the ion structure of organic ions. The sensitivity and SI/EI ratio in Table 1 is detailed in later sections. 

In this section, first we modify an earlier definition of a partial safety case argument structure [3], [7], adding a labeling function for node contents. Then, we give a formal definition of a pattern, clarifying conditions on multiplicity and recursion. Subsequently, we give a formal semantics to patterns as the set of their concrete instances, via a notion of pattern refinement. 

Definition 2 (Pattern). A pattern V is a tuple N, l,t,p, m, c, ->), where N, - ) is a directed hypergraph in which each hyperedge has a single source and possibly multiple targets, the structural conditions from Definition 1 hold, and I, t, p, m, and c are labeling functions, given as follows ...
