Quantum corrections to the dynamics of interacting bosons: beyond the truncated Wigner approximation [PDF]

, 2003
We develop a consistent perturbation theory in quantum fluctuations around the classical evolution of a system of interacting bosons. The zero order approximation gives the classical Gross-Pitaevskii equations.

Stabilization of test particles in Induced Matter Kaluza-Klein theory [PDF]

, 2006
The stability conditions for the motion of classical test particles in an $% n $-dimensional Induced Matter Kaluza-Klein theory is studied. We show that stabilization requires a variance of the strong energy condition for the induced matter to hold and ...

Recent proposals to estimate transient error within the classical test theory tradition

SA Journal of Industrial Psychology, 2006
Reliability is conceptually defined in terms of consistency across test occasions but coefficient alpha, the most popular reliability estimation method, precludes the examination of such consistency.
