    Abstract
    We study the liquid-crystalline phase behavior of a concentrated suspension of helical flagella isolated from Salmonella typhimurium. Flagella are prepared with different polymorphic states, some of which have a pronounced helical character while others assume a rodlike shape. We show that the static phase behavior and dynamics of chiral helices are very different when compared to simpler achiral hard rods. With increasing concentration, helical flagella undergo an entropy-driven first order phase transition to a liquid-crystalline state having a novel chiral symmetry.

      Ecosystem biogeochemistry considered as a distributed metabolic network ordered by maximum entropy production 

      Vallino, Joseph J. (2009-09-18)
      We examine the application of the maximum entropy production principle for describing ecosystem biogeochemistry. Since ecosystems can be functionally stable despite changes in species composition, we utilize a distributed ...

      Multichannel maximum entropy method of spectral analysis applied to offshore structures 

      Briggs, Michael Jeffrey (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1981-06)
      The multichannel Maximum Entropy Method (MEM) of spectral analysis is developed and applied in the dynamic analysis of offshore structures. Two different algorithms are implemented and compared with the conventional ...
