Most of us have been shocked after walking across a carpet and touching a metal doorknob. The build-up of charge—“static” electricity—on the surface of some nonconductors because of friction is called triboelectricity. We are unaware of the build-up of charge on our bodies as wewalk and only notice it upon discharge when it briefly stimulates our pain-sensing neurons; it is essentially an epiph...

In gauge theories like the standard model, the electric charges of the fermions can be heavily constrained from the classical structure of the theory and from the cancellation of anomalies. We argue that the anomaly conditions are not quite as well motivated as the classical constraints, since it is possible that new fermions could exist which cancel potential anomalies. For this reason we exam...

18 ANSYS ADVANTAGE ISSUE 2 | 2017 Leading the Electric Vehicle Charge The battery management system plays a critical role in today’s electric vehicles: It monitors the state of the battery, manages its operation to optimize vehicle performance and battery life, and ensures the safety of occupants. Researchers at National Electric Vehicles Sweden (NEVS) who are developing the BMS for their next-...

By treating magnetic charge as a gauge symmetry through the introduction of a " magnetic " pseudo four-vector potential, it is shown that it is possible, using the 't Hooft-Polyakov construction, to obtain a topological electric charge. The mass of this electrically charged particle is found to be on the order of 1 137 M W as opposed to the much larger mass (on the order of 137M W) of the magne...

It is important to reveal the relations of physical factors to deposition of contaminants on insulator. In this paper, the simulation model of high voltage end of insulator was established to study the force and motion characteristics of particles affected by electric force and airflow drag force near the ultra-high voltage direct current (UHVDC) insulator. By finite element method, the electri...

Previously, I have proposed a model for post-attachment chromosome motions based on electrostatics and assumptions regarding net charge on kinetochores and the pericentriolar material of centrosomes. The present work shows that given the electric dipole nature of tubulin, layered water associated with electric charge, and the dynamic instability of microtubules, it is possible to account for th...

For pure SU(N) gauge theory without quarks ’t Hooft’s gauge invariant electric and magnetic fluxes [1] describe, respectively, the effect of a static fundamental color charge and a center monopole in a finite volume. The partition function of a certain amount of electric/magnetic flux yields the free energy of a static electric/magnetic charge with boundary conditions to imitate the presence of...

– We discuss the influence of the superconducting transition in a film on the fluorescence spectrum of a single molecule located nearby. We show that single molecule spectroscopy (SMS) should be an appropriate tool to detect the electric charge associated with a vortex line. Also we argue that an electric field must appear at the boundaries between normal and superconducting regions of the inte...

Three different general approaches for calculating the electromagnetic fields at any point in space from a lightning return stroke, which is modelled as an extending linear antenna, are reviewed and compared. In the first approach, known as the dipole approach, the electric field is completely expressed in terms of the retarded current on the lightning channel and in the second approach the ele...
