Entropy of the hard-core model.

The entropy of the hard-core model is analyzed subject to dimension, system size and particle density. Inspired by the exactly solvable one-dimensional case and the results from a virial expansion, we suggest a scaling relation for the two-dimensional and three-dimensional case. These relations are compared with numerical results, obtained by a modified Widom's particle insertion method. The notion of finite size effects, relevant for atomic glass-forming systems, is discussed in the context of the present results.

[An unusual case of psychosis caused by long-term administration of a scopolamine membrane patch. Paranoid hallucinogenic and delusional symptoms]. / Ungewöhnlicher Fall einer Psychose infolge einer Langzeiteinwirkung mit einem Skopolaminmembranpflaster. Paranoid-halluzinatorische und delirante Symptomatik.

We report on a psychosis caused by application of a transdermal scopolamine patch for over 15 days. In the literature there is no mention of a case in which scopolamine had such an influence nor are any cases reported in which paranoid-hallucinatory symptoms continued 11 days after removing the patch.
