Figure 2. Molecule 1 displaying YES logic via fluorescence output from a proton input.

Figure 4. Molecule 3 displaying AND logic via fluorescence output using sodium and proton inputs. Note that only one of the two PET paths shown would occur in a given excited state 3a.

Avoidance of double counting of the same impacts in several categories (e.g. by erroneously taking into consideration the impacts acidification and proton input in separate categories)... 

Relationship between proton input with acid rain and aluminum speciation in soils of Japanese Cedar ecosystems is considered in Box 2. 

Figure 5 Effeets of atmospherie NEI or NEi input on soil proton balanees. The produetion of Ei depends on the form of NEi input and the fate of the NEi ion. represents a metal ion that might be leaehed from the soil. (Taken from Sutton et aP. ...

One element of database generation that is a key consideration is whether to expand the representative compounds to include alternative tautomers, protonated and deprotonated forms of the molecule, and also to enumerate stereochemistry fully if not specified in the input. Depending on the molecules in question and the options considered, these can lead to a 10-fold increase in the size of the database to be explored. However, such an expansion is necessary if methods are used that are sensitive to such chemical precision (e.g., docking). For 3D similarity searching, it is sometimes more efficient to consider various modifications to the query, leading to multiple searches against a smaller database. 

Using protons from water (and an energy input) for reaction with metal-coordinated dinitrogen (the metalloenzyme nitrogenase)... 

Giant dipole resonance. Isovector giant resonances contain information about the SE through the restoring force. In particular the excitation of the isovector giant dipole resonance (GDR) with isoscalar probes has been used to extract A R/R [32], In the distorted wave Bom approximation optical model analysis of the cross section the neutron and proton transition densities are needed as an input. For example, in the Goldhaber-Teller picture these are...
