potassium channels allow potassium flux and are essential for the generation of electric current acrossexcitable membranes. potassium channels are also the targets of various intracellular controlmechanisms; such that the suboptimal regulation of channel function might be related to pathologicalconditions. realistic studies of ion current in biologic channels present a major challenge for compu...

flory fox, kurata-stockmayer, berry, inagaki-suzuki-kurata, stockmayer-fixman and ahmad-baloch methods based on the excluded volume theory have been applied to poly(vinyl chloride)-cyclohexanone system to obtain kq and the radius of gyration. a discussion on the reliability of these methods is given. the stockmayer-fixman and ahmad-baloch methods are found to be equally applicable.

This report presents the analyses, results and recommendations of an investigation into the specification and determination of a platform's roll radius of gyration and its influence on the measured or predicted roll response of a maritime platform. The investigation and report seek to resolve known deficiencies in the specification and determination of roll radius of gyration and provide direct...

Using the path integral approach, we obtain characteristic functions of gyration radius distributions for Gaussian star and rosette macromolecules. We derive analytical expressions cumulants both distributions. Applying steepest descent method, estimate probability distribution in limit a large number arms two limiting regimes: strongly expanded collapsed show that cases, regime relative to its...

Using laser fluorescence microscopy, we study the shape and dynamics of individual DNA molecules in slitlike nanochannels confined to a fraction of their bulk radius of gyration. With a confinement size spanning 2 orders of magnitude, we observe a transition from the de Gennes regime to the Odijk regime in the scaling of both the radius of gyration and the relaxation time. The radius of gyratio...

We present molecular dynamics simulations of a polymer in a solvent of monomers. We have studied the influence of the “quality” of the solvent on the radius of gyration. This is modelled by varying the emp of a Lennard-Jones potential, which describes the interaction of the monomers with the polymer segments. Starting from an isolated chain (c,~= 0), the introduction of a very small interaction...

Numerical studies of the average size of trivially knotted polymer loops with no excluded volume were undertaken. Topology was identified by Alexander and Vassiliev degree 2 invariants. Probability of a trivial knot, average gyration radius, and probability density distributions as functions of gyration radius were generated for loops of up to N = 3,000 segments. Gyration radii of trivially kno...
