The accuracy of the formula derived by Drorbaugh and Fenn (Pediatrics 16: 81-86, 1955) for calculating tidal volume (VT) from the phasic pressure change measured when an animal breathes in a closed chamber has recently been challenged. Epstein and Epstein (Respir. Physiol. 32: 105-120, 1978) argue that the formula may underestimate VT by up to 30% and(More)
This article presents practical numerical recipes for simulating high-temperature and non-equilibrium quantum spin systems that are continuously measured and controlled. The notion of a " spin system " is broadly conceived, in order to encompass macroscopic test masses as the limiting case of large-j spins. The simulation technique has three stages: first(More)
This article presents numerical techniques for simulating high-temperature and non-equilibrium quantum spin systems that are continuously measured and controlled. The notion of a " spin system " is broadly conceived, to encompass test masses as the limiting case of large-j spins, and in general the systems simulated are spatially inhomogeneous. The(More)
