Noncovalent association of proteins to specific target sites on DNA--a process central to gene expression and regulation--has thus far proven to be idiosyncratic and elusive to generalizations on the nature of the driving forces. The spate of structural information on protein--DNA complexes sets the stage for theoretical investigations on the molecular thermodynamics of binding aimed at identif...

There is no literature mentioning the electromechanical behavior of micro structures driven by traveling electrostatic forces. This article is thus the first to present the dynamics and stabilities of a micro-ring subjected to a traveling electrostatic force. The traveling electrostatic force may be induced by sequentially actuated electrodes which are arranged around the flexible micro-ring. T...

In order to accurately determine the electrostatics of Ultra-Thin-Body (UTB) devices, semi-empirical tight-binding (TB) approach is widely used for calculating channel thickness dependent band structure any material at those temperatures where TB parameters are available (generally defined 0 K and 300 K). this work, we analyze variation Si, Ge, GaAs over different thicknesses K, show that curva...

We discuss several results in electrostatics: Onsager’s inequality, an extension of Earnshaw’s theorem, and a result stemming from the celebrated conjecture Maxwell on number points electrostatic equilibrium. Whenever possible, we try to provide brief historical context references.

The Ball Bearing High Voltage generator is a fairly simple and transparent apparatus that can serve as tool to motivate conceptual descriptions calculations in electrostatics are normally presented our students rather dry matter-of-fact fashion.

The coat protein of positive-stranded RNA viruses often contains a positively charged tail that extends toward the center of the capsid and interacts with the viral genome. Electrostatic interaction between the tail and the RNA has been postulated as a major force in virus assembly and stabilization. The goal of this work is to examine the correlation between electrostatic interaction and amoun...
