Persistence length lp
Formally, the persistence length, P, is defined as the length over which correlations in the direction of the tangent are lost. In a more chemical based manner it can also be defined as the average sum of the projections of all bonds j ≥ i on bond i in an infinitely long chain. Zobraziť viac The persistence length is a basic mechanical property quantifying the bending stiffness of a polymer. The molecule behaves like a flexible elastic rod/beam (beam theory). Informally, for pieces of the … Zobraziť viac Persistence length measurement of single stranded DNA is viable by various tools. Most of them have been done by incorporation of the worm-like chain model. For example, two … Zobraziť viac For example, a piece of uncooked spaghetti has a persistence length on the order of $${\displaystyle 10^{18}}$$ m (taking in consideration a Young modulus of 5 GPa and a radius of 1 mm). Double-helical DNA has a persistence length of about 390 Zobraziť viac • Polymer • Worm-like chain • Freely jointed chain Zobraziť viac WebDownloadable (with restrictions)! A dynamical mean field theory is used to predict the end-monomer mean square displacement of single-stranded DNA and finally estimate two important parameters—the persistence length lp and the length per base ld. Both parameters are set free, and finally reach optimum values by fitting the theoretical data to …

WebSingle semiflexible polymer chains confined in a planar slit geometry between parallel nonadsorbing repulsive walls a distance D apart are studied by Monte Carlo simulations of a lattice model, for the case of good solvent conditions. The polymers are modeled as self-avoiding walks on the simple cubic lattice, where every 90° kink requires a bending energy …
WebPersistence length is a significant criterion to characterize the semi-flexibility of DNA molecules. The mechanical constraints applied on DNA chains in new single-molecule experiments play a complex role in measuring DNA persistence length; however, there is a difficulty in quantitatively characterizing the mechanical constraint effects due to their …
Web4. mar 2024 · Edit: oh, and lp.pl should be lp.lp. I guess that is the cause of the mailing list issue. I think this is a neat example for a rather suboptimal choice of variable names. IMHO we should replace lp and lb by persistence_length and bond_length and deprecate the old names.
