Kertesz on Fat Graphs?

The identification of phase transition points, βc, with the percolation thresholds of suitably defined clusters of spins has proved immensely fruitful in many areas of statistical mechanics. Some time ago Kertesz suggested that such percolation thresholds for models defined in field might also have measurable physical consequences for regions of the phase diagram below βc, giving rise to a “Ker...

appeared, predator-prey interactions resulted in more selection pressure. Exceptionally preserved fossil occurrences reveal an increase in ecological complexity over time. Escalation in the number of different modes of life includes the exploitation of a greater range of levels above and below the sediment surface (tiering), as well as diversification of feeding mechanisms and modes of locomoti...

John Denis Sargan 1924 — 1996

J. D. Sargan was born on August 23, 1924, in Doncaster, Yorkshire, where he spent his childhood. He was Emeritus Professor of Econometrics at the London School of Economics when he died at his home in Theydon Bois, Essex, on Saturday 13 April, 1996. He received his secondary education at Doncaster Grammar School and, at the age of 17, gained a State Scholarship for entrance to St. Johns College...

The past two years have seen the rapid development of new recognition methods for protein structure prediction. These algorithms ’thread’ the sequence of one protein through the known structure of another, looking for an alignment that corresponds to an energetically favorable model structure. Because they are based on energy calculation, rather than evolutionary distance, these methods extend ...
