Determination of End-to-End Distances in Oligomers by Pulsed EPR
The Journal of Physical Chemistry, 1996Conformations of end-labeled alkanes in a rigid polymer matrix were investigated using the pulsed double electron-electron resonance (DEER) method. To this end, dipolar spectra of a series of aliphatic dicarbonic acids with 8−20 methylene units and chain ends bifunctionalized with nitroxide radicals were recorded in a polystyrene matrix. The biradicals

End to end distance measurement algorithms in biology sequences
2020 15th Iberian Conference on Information Systems and Technologies (CISTI), 2020Biological information inside the DNA allows many characteristics variations. The translation of DNA from cells into sequences, is a very demanding computational process, which over the last decades biologists try to decode and understand. Search and match algorithms, mostly oriented to fuzzy search, are essential to define the structural biological ...

The distribution of end-to-end distances of the weakly bending rod model
Biopolymers, 2000The weakly bending rod model is an approximation to a worm-like chain in the limit where the ratio L(0)/P of the contour length L(0) to the persistence length P is not too large. The range of validity of the weakly bending rod model is investigated by deriving analytical expressions for its distribution of end-to-end distances P(L) and its moments and

Direct Measurement of the End‐to‐End Distance of Individual Polyfluorene Polymer Chains
ChemPhysChem, 2005AbstractWide‐field imaging of individual multichromophoric molecules and successive photobleaching were used to determine, accurately, the relative position of the chromophores in such systems. First, a polyphenylene dendrimer with well‐defined geometry was used to establish the accuracy in localization that can be obtained by this methodology.

Mean end-to-end distance of branched polymers
Journal of Physics A: Mathematical and General, 1979The author uses Monte Carlo methods to calculate the mean end-to-end distance of randomly branched polymer molecules. Molecular realisations are brown on the square and simple cubic lattices, and consist of N bifunctional monomers and Nf polyfunctional branching units of functionality f.

Persistence Length, End-to-End Distance, and Structure of Coarse-Grained Polymers
Journal of Chemical Theory and Computation, 2018Coarse-grained (CG) polymer simulations can access longer times and larger lengths than all-atom (AA) molecular dynamics simulations; however, not all CG models correctly reproduce polymer properties on all length scales. Here we coarse-grain atomistic position data from polyethylene (PE) and polytetrafluoroethylene (PTFE) melt simulations by combining

The end-to-end distance of RNA as a randomly self-paired polymer
Journal of Theoretical Biology, 2011In this paper, we present the end-to-end distance of randomly self-paired polymers (RSPPs). We define a randomly self-paired polymer as a linear polymer each of whose monomers has a probability, f ...

The Shapes of Random Walks with Fixed End-to-End Distance
1990Fixed length random walks embedded in d spatial dimensions are discussed. As a representation of polymers, they correspond to long chain molecules whose heads and tails are fixed in space. An exact analytical expression for the asphericity is presented that is valid in arbitrary spatial dimensionality.

An end-to-end distance measuring for mixed data based on deep relevance learning
Intelligent Data Analysis, 2020Distance Measuring between two mixed data objects is the basis of many learning algorithms. The complex relevance between heterogeneous – various types/scales – attributes has a significant influence on the measured results. In this paper, we propose an End-to-End Distance Measuring method for mixed data based on deep relevance learning, called E2DM ...
