Methods are presented to determine the effective macroion diffusion coefficient in the presence or absence of an electric field, using a unique analytical electrophoresis apparatus in which both electrophoretic mobility and steady-state electrophores

Charge is a fundamental property of macromolecules that is inextricably linked to their structure, solubility, stability, and interactions. Progress has been made on the theoretical and structural aspects of these relationships. However, for several

We study the class of shallow water equations of Camassa and Holm derived from the Lagrangian: $ L= \int \left( \frac{1}{2} (\varphi_{xxx}-\varphi_{x} )\varphi_{t} - {1 \over 2} {(\varphi_{x})^{3}} - {1 \over 2}\varphi_{x}(\varphi_{xx})^{2} - {1 \ove

We use a class of trial wave functions which are generalizations of gaussians to study single soliton approximate analytic solutions to the KdV equations. The variational parameters obey a Hamiltonian dynamics obtained from the Principle of Least Act

A method for analyzing deterministic dynamical systems is presented. New measures of complexity are proposed, based on fluctuation in net information gain and its dependence on system size. These measures are applied to one-dimensional cellular autom

Membrane-confined electrophoresis (MCE) is an electrophoretic transport method in which macromolecules in solution are confined within a cuvette through which a current flows. Small ions that can permeate the membranes permit current flow. The method
