Nanopores could potentially be used to perform single-molecule DNA sequencing at low cost and with high throughput. Although single base resolution and differentiation have been demonstrated with nanopores using ionic current measurements, direct sequencing has not been achieved because of the difficulties in recording very small (∼pA) ionic currents at a bandwidth consistent with fast transloc...

The surface roughness and material removal is investigated in electrorheological (ER) fluid-assisted polishing of tungsten carbide die. In this study, the microstructure of fibrous columns formed by particles perpendicular to the electrodes is observed by CCD when the electrical field is applied. The distribution of the electric field strength on the surface of workpiece was analyzed by ANSYS a...

The influences of pulsed electric fields on early physiological development in Arabidopsis thaliana were studied. Inside a 4-mm electroporation cuvette, pre-germination seeds were subjected to high-intensity, nanosecond electrical pulses generated using laboratory-assembled pulsed electric field system. The field strength was varied from 5 to 20 kV.cm and the pulse width and the pulse number we...

A balanced probe circuit is used to generate high B(1) magnetic field for sensitivity enhancement of multiple-quantum magic-angle spinning (MQMAS) experiment applied to low-gamma quadrupolar nuclei. Electrical balancing of the sample coil can cut the peak voltage by a half, therefore improving the power handling when generating a two-fold higher B(1) field. Experimental results, illustrated her...

[Purpose] The aim of this study was to evaluate the effect of oscillating electrical field stimulation on motor function recovery and myelin regeneration in rats with spinal cord injury. [Subjects and Methods] A rat model of spinal cord injury was constructed by using the Allen weight-drop method. These rats were randomly divided into normal, spinal cord injury, and spinal cord injury + oscilla...

Classically, electrical synapses were thought only to increase the speed and synchrony of neural activity, but recent results suggest that rectifying electrical synapses can act as coincidence detectors, and regulation of the strength of other electrical synapses can enhance oscillatory or asynchronous neural activity.

The formulation of a method to solve steady-state electromagnetic field problems involving laminar eddy currents is described. Iron nonlinearity is included. The formulation is implemented using finite elements and the problems associated with the solution of the resulting nonlinear equations discussed. Experiments with a Newton-Raphson iteration and modifications to it are described and a best...
