We investigate the dynamics of a three-state stochastic lattice gas, consisting of holes and two oppositely " charged " species of particles, under the influence of an " electric " field, at zero total charge. Interacting only through an excluded volume constraint, particles can hop to nearest neighbour empty sites. With increasing density and drive, the system orders into a charge-segregated s...
Instanton and seven-brane solutions of type IIB supergravity carrying charges in the Ramond-Ramond sector are constructed. The singular seven-brane has a quantized R ⊗ R ‘magnetic’ charge whereas its dual is the instanton, which is non-singular in the string frame and has an associated global ‘electric’ charge. The product of these charges is constrained by a Dirac quantization condition. The i...
Electricity is a general term for a variety of phenomena resulting from the presence and flow of charge, and “Electrotechnics” is the study or the science of practical and industrial applications of electricity. On the other side, the space is mainly characterized by the interaction of energetic charged particles with electric and magnetic fields, which justifies the claim «the space composes a...
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...
In-Flight ElectroSpraying (IFES) is a novel approach to generate electrically charged micrometer-sized and/or nanometer-sized progeny drops in a controlled manner. This is accomplished in ight, beginning with millimeter-sized parent drops. The breakup of charged drops that is exploited in IFES also occurs (sometimes unwantedly) in conventional electrospraying, electrospinning, and electrospray ...
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...
Electric field induced by charge oscillation has been investigated by simulation of the electric field distribution using the finite-difference frequency-domain method. In addition, the electric field was induced by spatial oscillation of a sample to which a DC voltage was applied. The simulation and evaluation of the electric field verified that the efficiency for inducing the electric field h...
It is theoretically shown that the effective carrier photogeneration rate in a longitudinal photoresistor, which directly initiates conversion of radiation into electric current, can be positive, zero, or negative, and significantly exceeds absolute value true rate. The effects are due to photoinduced local space charge. Keywords: charge, absorption coefficient.
[1] The ionosphere-Earth current density Jz creates space charge at the upper and lower boundaries of layer clouds. This occurs because clouds have an order of magnitude lower conductivity than the clear air at the same altitude, and as the current density flows through the boundaries, it creates a gradient of electric field that must be satisfied by the accumulation of space charge, according ...
