A simple model for multi-ion permeation. Single-vacancy conduction in a simple pore model

Multi-ion conduction bands in a simple model of calcium ion channels.

We report self-consistent Brownian dynamics simulations of a simple electrostatic model of the selectivity filters (SF) of calcium ion channels. They reveal regular structure in the conductance and selectivity as functions of the fixed negative charge Qf at the SF. With increasing Qf, there are distinct regions of high conductance (conduction bands) M0, M1, M2 separated by regions of almost zer...

A Simple Theoretical Model for Prediction of Phase Inversion

Phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between Oil-in-Aqueous dispersion and Aqueous-in-Oil dispersion. A theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. Experimental data from the literature were used to validate the model and results were c...

Comments on Nonfinite Adverbial Patterns in English Prose Fiction: A Simple Model for Analysis and Use

This study aims to present an accessible model of some frequent nonfinite adverbial types occurring in English prose fiction. As its main syntactic argument, it recognizes that these adverbials are mostly elliptical in that there are some dependent-clause markers one can assume to be implicit when supplying those elements back into the clause complex. Some comments are provided at the end on th...

A simple model for accretion disks in the post-Newtonian approximation

p { margin-bottom: 0.1in; direction: ltr; line-height: 120%; text-align: left; }a:link { } In this paper, the evolution of accretion disks in the post-Newtonian limit has been investigated. These disks are formed around gravitational compact objects such as black holes, neutron stars, or white dwarfs. Although most analytical researches have been conducted in this context in the framework o...
