Radial Electric Fields for Improved Tokamak Performance
The influence of externally-imposed radial electric fields on the fusion energy output, energy multiplication, and alpha-particle ash build-up in a TFTR-sized, fusing tokamak plasma is explored. In an idealized tokamak plasma, an externally-imposed radial electric field leads to plasma rotation, …

Electric fields and transport in optimized stellarators
… A compact expression is derived for the radial electric field Er which is largely independent of the details of the magnetic field. Another issue in the neoclassical theory of stellarators which has not been fully resolved is the validity of the so-called monoenergetic approximation, in which …

Pancreatic Cancer: Oncomicrobes, Electric Fields, and Fluid Flow
… compartment. This approach employs pulsed electric fields to achieve controlled permeabilization of host cell membranes through precise modulation of electric field strength. By combining pulsed electric fields with a standard-of-care antibiotic, we achieved greater than 99% clearance of …

Breakdown characteristics of nonuniform electric fields in crossflows
… the breakdown characteristics of the nonuniform electric fields established between two spheres and between two points in a crossflow was conducted and the results were then compared to the breakdown characteristics in quiescent air. The aluminum spheres used in this investigation ranged in …

Thermal bubble behaviour in liquid nitrogen under electric fields
… behaviour changes in liquid nitrogen (LN2) under electric fields. Cryogenic liquids such as LN2 have been used not only as the coolant but also as the electrical insulator in superconducting and cryogenic apparatus. However, bubbles are easily formed in these liquids by even moderate heating …

Effects of weak electric fields on long-term synaptic plasticity
… (tDCS) is a technique where a weak direct electrical current is applied to the scalp with the goal of stimulating the brain. There is tremendous interest in the use of tDCS for treating brain disorders and improving brain function. However, the effects of tDCS have been highly variable …

The Effect of High Transverse Electric Fields on Thermal Radiation
… assumptions of Planck's Law is that the electric field at an emitting surface is zero. Applying a large electric field to the surface, thereby inducing a nonlinear polarization of the surface, could violate this assumption. A flared concentric cylinder blackbody radiation source has been …

Collective behavior of colloidal suspensions under electric fields and confinement
… suspensions of spherical particles under electric fields and confinement. We first analyze the nonlinear dynamics of non-colloidal, uncharged ideally polarizable spheres freely suspended in a viscous electrolyte in a uniform electric field. Specifically, we investigate two nonlinear …
