A well-known calculation shows the evolution of a quantum system being slowed down, or even obstructed, when the system is merely observed.
The model is based on a new pseudo-front tracking technique for the calculation of the evolution of interfaces that are governed by solute diffusion and the Gibbs Thomson effect.
The method is applicable for calculation of the evolution of particle distribution function f including as special cases strong plasma pressure profile evolution by transport and formation of neoclassical flows.
First, using calculations similar to those used in Equations 13 18 and Appendix, Calculations for the evolution of parental care, we calculate the moments of reproduction for a focal male and a focal female in the presence of trade-offs to find the fitness components of a focal individual (w v i m, w v i f, Equation 4).
Second, polygyny affects the efficacies of selection Km and Kf (Appendix, Calculations for the evolution of parental care, for calculations).
These moments are the same as those appearing in the calculation of focal fitness and in addition include the covariance between the number of male and female offspring produced by a resident individual (Appendix, Calculations for the evolution of parental care, for calculations).
Values of n near 100,000 have been used in calculations determining the evolution of galaxies of stars.
The first calculations of the evolution of primordial protostars with continuous accretion were carried out by Stahler et al. (1986a, 1986b) and Omukai and Palla (2001, 2003).
Calculations illustrate the evolution of the temperature profile during the growth of the instability.
One of the critical problems in projecting soil bioengineering interventions is the difficulty in developing precise calculations of the evolution of the structures and the type and combination of vegetation plantations that are planned for the particular site and problem.
