Two-time Green's functions and the spectral density method in nonextensive classical statistical mechanics.

The two-time retarded and advanced Green's function technique is formulated in nonextensive classical statistical mechanics within the optimal Lagrange multiplier framework. The main spectral properties are presented and a spectral decomposition for the spectral density is obtained. Finally, the nonextensive version of the spectral density method is given and its effectiveness is tested by exploring the equilibrium properties of a classical ferromagnetic spin chain.

[Spontaneous recovery of sinus rhythm in long-standing mitral fibrillation].

The case of a 73-year-old woman with a 10 year history of mitral valvulopathy in atrial fibrillation is reported. On two occasions spontaneous recovery of sinus rhythm occurred. The first, lasting about 48 hours, followed acute digitalis poisoning. On the second occasion there was a slight intermittent 1st degree A-V blockage, though no glucoside had been taken for about 5 months.
