Heat conduction in polymer chains with controlled end-to-end distance

The Journal of Chemical Physics, 2020
The low thermal conductance of polymers is one of the major drawbacks for many polymer-based products. However, a single polymer chain when stretched can have high thermal conductivities. We use non-equilibrium molecular dynamics simulations to study the steady-state thermal conductance along finite macromolecules under mechanical control of the end-to-

Endpoint Cluster Identification for End-to-End Distance Estimation

2006 IEEE International Conference on Communications, 2006
Distributed systems such as peer-to-peer networks and distributed servers can optimize their performance by adapting to the underlying network. End-to-end measurements are an important basis for such adaptivity. Although most applications measure similar properties of the network, the measurements are mostly done in application-specific ways.

End to end distance measurement algorithms in biology sequences

2020 15th Iberian Conference on Information Systems and Technologies (CISTI), 2020
Biological 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, 2000
The 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, 2005
AbstractWide‐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, 1979
The 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, 2018
Coarse-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, 2011
In 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 ...

End-to-end Text-dependent Speaker Verification Using Novel Distance Measures

Interspeech 2018, 2018
This paper explores novel ideas in building end-to-end deep neural network (DNN) based text-dependent speaker verification (SV) system. The baseline approach consists of mapping a variable length speech segment to a fixed dimensional speaker vector by estimating the mean of hidden representations in DNN structure. The distance between two utterances is

Even Moments of the End-to-End Distance of Polymeric Chains

The Journal of Chemical Physics, 1968
A method is developed for calculating even moments 〈r2k〉 of the end-to-end distance r of polymeric chains, on the basis of the rotational-isomeric-state approximation for rotations about skeletal bonds. Expressions are obtained in a form which is applicable in principle to arbitrary k, but practical applications are limited by a tremendous increase in ...
