The Gorgonzola has a sparse layer of the pungent, salty cheese, which dresses the crust just right.
Powerful solar outbursts compress the field and force electrons to cascade down into the ionosphere, a sparse layer of the atmosphere hundreds of kilometers high.
Literature estimates of HSL production rates in V.fischeri indicate that such a sparse layer of individual cells, within a chamber that is flushed at this rate, would not be able to generate an endogenous HSL concentration above ~100 pM [ 20].
(a) Sparse layer-based representation (PSNR 29.62dB) with 1.18% of coefficients retained.
Fig. 5 Detail of the red cloth, in the middle of the blue dress, showing at least three distinct paint layers; a sparse greyish layer (based on Prussian blue and lead white), a flaking red layer (containing wax, a red lake, probably Alizarin, Vermillion and lead white), and a light pink underlayer (involving Geranium Lake, Vermilion and lead white).
We find that a denser homogeneous second layer promotes chimera in a sparse first layer, where chimeras do not occur in isolation.
Those include a sparse greyish layer based on Prussian blue and lead white, a flaking red layer containing wax, a red lake, probably Alizarin, Vermillion and lead white, and, finally, a light pink underlayer involving Geranium Lake (PR90 1), Vermilion and lead white.
A columnar arrangement of pyramidal cells was not found, neither in layer III nor in layer V. Layer II of FG2 had a rather high cell density with a clearly delineable border to the cell sparse layer IIIa.
However the only cells occupying the chamber (and producing HSL) are those forming a sparse single layer (cells are typically spaced > 20 μm apart) on the chamber window.
The cell sparse layer VI had no conspicuous border with lower layer V.
Cytoarchitectonically, the first three parts are classified as auditory parakoniocortices (internal: PaAi, external: PaAe, and caudodorsal: PaA) with prominent granularity in layer IV and sparse layer V.
