Mean Field Behaviour in a Local Low - Dimensional Model Hans - Martin Bröker and Peter Grassberger

We point out a new mechanism which can lead to mean field type behaviour in nonequilibrium critical phenomena. We demonstrate this mechanism on a two-dimensional model which can be understood as a stochas-tic and non-conservative version of the abelian sandpile model of Bak et al. [1]. This model has a second order phase transition whose critical behaviour seems at least partly described by the...

Leon Chesley (1908-2000)

Leon Chesley studied hypertension, or high blood pressure, in pregnant women during the mid-twentieth century. Chesley studied preeclampsia and eclampsia, two hypertensive disorders found in approximately five percent of all US pregnancies. In New Jersey and New York, Chesley devoted over forty years to researching preeclampsia and eclampsia, and conducted several long-term studies using the sa...

1908 Scheme I + - CHOC

A synthetic strategy for the preparation of the quinone antibiotic naphthyridinomycin is outlined. An efficient synthesis of key tricyclic intermediate 6 is described. Naphthyridinomycin (I) is an architecturally interesting broad spectrum antibiotic produced by Streptomyces lusitanus. 9 1 2 The structure elucidation of 1 in I974ia,b revealed its unique hexacyclic structure which shared a quino...
