PURPOSE The dose-response relationship for a relatively short length (4 mm) of rat spinal cord has been shown to be significantly modified by adjacent low-dose fields. In an additional series of experiments, we have now established the dose-volume dependence of this effect. METHODS AND MATERIALS Wistar rats were irradiated on the cervical spinal cord with single doses of unmodulated protons (...

We numerically investigate decoherence of a two-spin system (central system) by a bath of many spins 1/2. By carefully adjusting parameters, the dynamical regime of the bath has been varied from quantum chaos to regular, while all other dynamical characteristics have been kept practically intact. We explicitly demonstrate that for a many-body quantum bath, the onset of quantum chaos leads to si...

We present fast algorithms for the summation of Dyson series and inchworm Monte Carlo method quantum systems that are coupled with harmonic baths. The based on evolving integro-differential equations where most expensive part comes from computation bath influence functionals. To accelerate computation, we design reusing functionals computed in previous time steps to reduce number calculations. ...

Rice starch added to bath water was studied for its possible beneficial effects on impaired barrier function as evaluated by transepidermal water loss measurements. The forearm skin of healthy volunteers was irritated by sodium lauryl sulphate. Exposure to rice-starch-containing bath water--twice daily for 15 min--led to a 20% improvement on the healing capacity of damaged skin. The beneficial ...
