Identification of mathematical models is an important task for the design and the optimization of biokinetic processes. Monod or Tessier growth-rate models are often chosen by default, although these models are not able to represent the dynamics of all bacterial growth processes. This imperfect representation then affects the quality of the model prediction. This paper introduces an alternative...

Using an asymptotically exact real space renormalization procedure, we find that the Heisenberg antiferromagnetic spin-1 chain undergoes an impurity driven second order phase transition from the Haldane phase to the random singlet phase, as the bond distribution is broadened. In the Haldane phase and near the critical point, there is a Griffiths region in which the gap is filled and the suscept...

The observation has been made repeatedly that the induced synthesis of many different enzymes can be inhibited by a wide variety of carbohydrates (Benzer, 1953; Cohn, 1957, 1958; Epps and Gale, 1942; Gale, 1943; Happold and Hoyle, 1936; Herzenberg, 1958; Monod, 1941, 1947, 1956; Monod and Cohn, 1952; Neidhardt and Magasanik, 1956). One of the most characteristic and potent of these carbohydrate...

See related article by Pitot and Heidelberger, Cancer Res 1963;23: 1694–700. It is a virtually universal rule in science that if we step back to reflect upon a field currently viewed as extremely dynamic and novel, we find ourselves standing on the shoulders of thosewhose seminal observations gave birth to it far earlier. For those of us working in the fields of signal transduction and epigenet...
