We compare these results to predictions for both diffusive and ballistic transport, as the barrier rises on a length scale comparable to the mean free path.
The cathode thickness is comparable to the mean free path of the photoelectron allowing design concepts which are built on non-thermalized photoelectrons.
In these models, the size of paramagnetic agent compartment is comparable to the mean diffusion displacement of water molecules during the long RF pulses that are used to generate the off-resonance rotating frame.
In each case the impactor was a small (1/8 or 1/4 in) aluminum sphere fired at the meteorite target at ∼5km/s, comparable to the mean collision speed in the main-belt.
The channel length of this proposed transistor can be precisely controlled and easily fabricated to be comparable to the mean free path of electrons in air so that the device can operate in the air without performance degradation.
The shock front travels through the gas with a velocity comparable to the mean molecular velocity, so that the width of the shock front is only a few mean free paths (average distances traveled by the molecules between collisions).
Complications arising from the computational effort required for full quantum treatments of relatively large nanosystems (>100 nm) have hampered our ability to develop a full fundamental understanding of the new processes that emerge at dimensions comparable to the mean free path of electrons and at characteristic timescales of excited electron relaxation.
As shown by measurements of growth rates within the mask, the sub micron length scale of the channel opening is comparable to the mean free path of precursors in the gas phase, resulting in transport characteristics that can be described by an intermediate flow regime between continuum and free-molecular.
The upper estimate of 90 t/km2/y is comparable to the mean erosion rate estimated using the radionuclide method for uncultivated sites in Australia and is significantly lower than that measured at sites were vegetation cover was disturbed by livestock grazing prior to its exclusion from the alpine area in the 1940s CE.
The deviation started at a volume of 0.02 0.03 mm3, which is comparable to the mean pore volume.
This is comparable to the mean gradient found when determining a linear model for the same stage, returning a result of 0.0148 °C.s-1 [SD 0.008 °C.s-1].
