Heermann, and Roel van Driel<br/>Remarkably little is known about the higher-order folding motifs of the chromatin fiber inside the cell nucleus. Folding depends among others on local gene density and transcriptional activity and plays an important role in gene regulation. Strikingly, at fiber lengths above 5to10Mb the measured mea...<br/>[Phys. Rev. E 76, 051805] Published Tue Nov 27, 2007 Manfred Bohn, Dieter W.

L. Stella<br/>We study by Monte Carlo simulations a model of a knotted polymer ring adsorbing onto an impenetrable, attractive wall. The polymer is described by a self-avoiding polygon on the cubic lattice. We find that the adsorption transition temperature, the crossover exponent ϕ , and the metric exponent ν ...<br/>[Phys. Rev.
