Classical ensemble theory is compared to quantum mechanics. The remarkable feature is that classical ensemble theory, when suitably generalized, leads, for a system of one degree of freedom to two independent uncertainty relations. On the contrary classical trajectory theory which deals only...

Within the intensive care environment, large data-bases exist, recording patient, ICU, and hospital details. For the last 20 years, a number of competing algorithms have been developed to generate risk-adjusted outcomes for patients; the most well known is the APACHE II (acute physiology and...

The Friedrichs model of an unstable particle provides us with a non-trivial example of a dynamical system with a continuous spectrum. The non-unitary transformation operator which leads in our approach to a semi-group description of the time evolution of the system has been constructed in...

In the inhomogeneous collisionless system the collective modes are constructed in the physical representation using the method of subdynamics. They correspond to the explicit solutions of the non-linear Vlasov equation and they appear as the generalization of the van Kampen-Case treatment. The...
