with Q =
R ω 0 τdΩ = n serving as a quality factor for the CDE.
24 Deriving the CDE
from CDS units, i.e. molecular aggregates, like the DNA and/or its protein overcoats, in a biological system, will permit the definition of a particular cellular
quality value, Q. This is to some extent analogous to signal processing in communication systems, where the quality aspects of cavity resonators, like musical
instruments etc., play a vital role in transmitting resonating qualities. For that reason
the quality value Q = n, for e.g. somatic cells in a multicellular organism, transferring vital details regarding their traits, provides cell recognition through the
process of “molecular communication”.
The CDE exhibits an analogical irreducible unit Q in the basis H of CDS base
units. A simplified analysis of the associated system operator shows that its diagonal elements can be determined by a general probability measure, let us say
p A
ð Þ = Tr ρP A
ð Þ

Þ, (ρ a given density operator and P(A) a suitable self-adjoint
projection on Hilbert Space for the event A), and (1 – p(A))p(A) for any off-diagonal
one displaying ODLRO. An analogous analysis, cf. the CDS, leads through diagonalization and thermalization to a similar irreducible unit Q as in Eq. (4.11) but
generally with a different dimension m, in terms of H and the transformed F, cf. the
relations between h and f. The key difference is that τ = τ rel play the role of the short
(relatively speaking) time scale with a longer scale emerging through Q see more
below. We can now write down the propagator corresponding as (with

The Q-value should not be confused with the complex symmetric matrix Q.
