Centrifugal acceleration in the isotropic photon field

Scaling of acceleration in locally isotropic turbulence

where Dui/Dt denotes the time derivative following the motion of the fluid particle, and ui is velocity. Here, ν is the kinematic viscosity, ∇x ≡ ∂xn∂xn is the Laplacian operator, ∂ denotes differentiation with respect to the subscript variable, summation is implied by repeated indices, p is pressure divided by fluid density; density is constant. ε is energy dissipation rate per unit mass of fl...

Effect of the acceleration current on the centrifugal interchange instability

[1] The centrifugal interchange instability is the primary driver of radial plasma transport in the magnetospheres of Jupiter and Saturn. Most previous theoretical treatments of this instability have ignored the role of the acceleration current and have assumed that the divergence of the centrifugal drift current in the magnetosphere is closed by Pedersen currents in the underlying ionosphere, ...

Photon Acceleration-Based Radiation Sources

The acceleration and deceleration of photons m a plasma provides the means lbr a series of new radiation sources. Previous work on a DC to AC Radiation Converter (DARC source) has shown variable acceleration of photons having zero frequency (i.e., an electrostatic field) to belx~een 6 and 100 GHz (I-3). These sources all had poor guiding characteristics resulting in poor power coupling froln th...

Two-photon fluorescence isotropic-single-objective microscopy.

Two-photon excitation provides efficient optical sectioning in three-dimensional fluorescence microscopy, independently of a confocal detection. In two-photon laser-scanning microscopy, the image resolution is governed by the volume of the excitation light spot, which is obtained by focusing the incident laser beam through the objective lens of the microscope. The light spot being strongly elon...
