V-Models

The composite model is a combination of the monoparametric v model with the simple branching model. This method has proven useful in modelling amino acid, peptide and protein properties49. It is an improvement over the simple branching model and requires only one additional parameter. 

Much of the preclinical data generated with regard to these vaccines entailed the use of one of two animal model systems simian immunodeficiency virus infection of macaque monkeys and HIV infection of chimpanzees. Most of the positive results observed in such systems have been in association with the chimp-HI V model. However, no such system can replace actual testing in humans.

Figure 1 ISO V model adapted for analytical method validation...

The ISO V model for system development life cycle in computer software validation is a structured description of such a process. In this instance, the basic V model has been adapted for analytical method validation and is shown in Figure 1. 

Each layer of the ISO V model is dependent upon the layer below and represents stages in the process. Broadly speaking, the boxes in the left-hand portion of the V model represent the aims and objectives of the validation. The boxes in the right-hand portion of the V model contain the processes and procedures that must be carried out successfully and be properly documented to demonstrate that these specified aims and objectives have been met. At the fulcrum of the model is the development process itself. 

If the kets label individual states, i.e.. points in projective space, and if addition makes no sense in projective space, what could this addition mean The answer lies with the unitary structure (i.e., the complex scalar product) on V and how it descends to P(y). If V models a quantum mechanical system, then there is a complex scalar product ( , ) on V. Naively speaking, the complex scalar product does not descend to an operation on P(V). For example, if v, w e V 0 and v, w Q v/e have u 2v but (v, w) 2 v, w) = 2v, w). So the bracket is not well defined on equivalence classes. Still, one important consequence of the bracket survives the equivalence orthogonality.
