modulation

 [mod″u-la´shun]
the normal capacity of cell adaptability to its environment.
antigenic modulation the alteration of antigenic determinants in a living cell surface membrane following interaction with antibody.

mod·u·la·tion

(mod'yū-lā'shŭn),
1. The functional and morphologic fluctuation of cells in response to changing environmental conditions.
2. Systematic variation in a characteristic (for example, frequency, amplitude) of a sustained oscillation to code additional information.
3. A change in the kinetics of an enzyme or metabolic pathway.
4. The regulation of the rate of translation of mRNA by a modulating codon.

QAM modulation provides a better transmission performance because QAM constellation points are considerably more scattered in comparison to PSK constellation points.
Figure 6(a) shows the relationship between the electron concentration and modulation voltage for three structures, and Figure 6(b) shows the relationship between the hole concentration and modulation voltage.

If we understand the first form of control--direct intervention--as moulding [moulage], then this second form of control can be understood in terms of modulation. In Deleuze's own words: 'enclosures are moulds, distinct mouldings, but controls are modulations, like an auto-deforming mould that would continuously change from one moment to the other'.
