Nonequilibrium spin-glass dynamics from picoseconds to a tenth of a second.

We study numerically the nonequilibrium dynamics of the Ising spin glass, for a time spanning 11 orders of magnitude, thus approaching the experimentally relevant scale (i.e., seconds). We introduce novel analysis techniques to compute the coherence length in a model-independent way. We present strong evidence for a replicon correlator and for overlap equivalence. The emerging picture is compatible with noncoarsening behavior.

[The role of dietary carbohydrates and proteins in the determination of postprandial insulin requirements, evaluated by artificial pancreas, in type I diabetics]. / Ruolo dei carboidrati e delle proteine della dieta nel determismo del fabbisogno insulinico post prandiale valutato mediante pancreas artificiale in soggetti diabetici di tipo I.

Aim of this work is to evaluate the relative role of ingested carbohydrates and proteins in determining post-prandial insulin requirement in type I diabetic patients by means of artificial pancreas 5 male diabetics were given two times a day a diet with a high amount of carbohydrates (140g) or with a high amount of proteins (120g) while connected to the Biostator. Basal and post-prandial required insulin was evaluated. Post-prandial insulin requirement after high proteins meals did not appear greater than basal requirement, while insulin requirement after high carbohydrates meals appeared statistically greater than basal requirement. No difference could be observed between insulin requirement after morning (h. 10.00) or afternoon (h. 16.00) meals. These results could be of some help in optimizing the portable infuser-treated diabetic patients.
