Myrmecia: Volume 57, Part 3

Entropy 2001, 3, 27-57

In a recent study by Kier, Cheng and Testa, simulations were carried out to monitor and quantify the emergence of a collective phenomenon, namely percolation, in a many-particle system modeled by cellular automata (CA). In the present study, the same setup was used to monitor the counterpart to collective behavior, namely the behavior of individual particles, as modeled by occupied cells in the...

Encounter with a Geometer, Part II, Volume 47, Number 3

326 NOTICES OF THE AMS VOLUME 47, NUMBER 3 Riemannian Geometry Starting in the late 1970s, MG completely revolutionized Riemannian geometry. I mention in this section some results that reflect my taste. This article contains only a small bibliography; further references may be found in my 1998 survey article in Jahresbericht der Deutschen Mathematiker-Vereinigung.1 Except for obvious cases, eve...

Mössbauer diffractometry on polycrystalline 57 Fe 3

A Mössbauer powder diffractometer was used to measure diffraction patterns from polycrystalline foils of Fe3Al. The intensities of Bragg diffractions were measured as a function of the energy of the incident photon. The bcc fundamental diffractions showed large changes in intensity as the incident energy was tuned through the nuclear resonances. These variations of diffraction intensity with in...
