In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the relative location of nucleus with respect to the electrical field, we found that the observed cell rotation was ...

A neutrino oscillation experiment aims to the observation of the transformation of a neutrino of a given flavour into a neutrino of a different flavour. A beam of neutrinos is produced through the decay of charged pions which in turn are produced in the collision of high energy accelerated protons impinging on a thick target. A series of magnetic horns is used to focus charged particles produced ...

In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of the electric field. DEP is caused by polarization of the DNA particle. Two different electrode geometries ...

Capacitive energy extraction based on double layer expansion (CDLE) is a new method devised for extracting energy from the exchange of fresh and salty water in porous electrodes. First suggested by D. Brogioli, it is enclosed in a group of emergent technologies jointly known as Capmix methods. The CDLE technique is based on the fact that the capacitance of the electric double layer (EDL) ...

Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis . However, there are limitations on the performance of these nanosensors in solutions at high ionic strength. This is because the electric field induced by the binding of biomolecule is partially screened on length-scales larger than the ...

Rotating Magnetic Field Eddy current technique is a promising technique for inspection of flaws in metallic tubular components. Three primary coils, 120 degrees apart in space, are excited with three phase current source, by virtue, a rotating magnetic field polarised in radial direction is generated. This radial field interacts with metallic tube and generates ...

The magnetic field gradient produced by an electromagnet gripper head depends on its design. Stochastic Methods offer certain robustness to the design optimization process. In this paper, Improved Discrete Particle Swarm Optimization (IDPSO) searching technique is applied to the shape and magnetic field gradient optimization of an electromagnet head. The magnetic field and forces are ...

This paper shows how a time-dependent and non-linear simulation of the dynamic operation behavior of an induction machine is executed by means of the \"Rotating Machinery\" interface from COMSOL Multiphysics 4.2a. The two-dimensional FEM model is connected to electrical circuits by coupling the physics \"Rotating Machinery\" and \"Electrical Circuit\" interfaces. These circuits include the ...

We present a simplified 3D model that simulates the operation of a linear microscale integrated ion trap. It employs a set of metalized electrodes, which are formed on top of an insulator layer on silicon substrate. The confinement in all three dimensions is provided by the application of the specific AC and DC voltages to the corresponding trap electrodes. The distribution of the trapping ...

After spinal cord injury (SCI) the functions of the lower urinary tract are often disrupted and may have fatal consequences for the patient. It has been shown that using a transrectal probe developed by Craggs et al., through conditional transrectal stimulation of pudendal nerve, it is possible to treat hyperreflexia in some of the SCI patients. To maximise the efficacy of this type of ...
