A comparison with non-gradient samples with discrete composition revealed a significant improvement, specifically in the case of hard-soft-hard gradients.
The method addresses two challenges in it: First, the optimization problem is highly non-convex, which makes hard for gradient-based methods to reach global minima.
A problem with this approach is that the resulting hard transition between the inpainted regions and their surroundings may again lead to strong gradients.
Three different gradient structures, hard-soft, hard-soft-hard, and soft-hard-soft, were realized and confirmed by position-dependent UV/Vis absorbance measurements.
We associate the rise in hardness during two stages with the strong strain gradient effects, the first stage is related with the small scale effects and the second stage with the strain gradient between the indenter and the hard substrate.
It's a continuous ascent all the way up to Passo dello Stelvio, at 2,758m, a ride described by cycling writer and expert Claude Droussent, as "very, very hard … with gradients up to 12.1% above 2,000m".
So by his own admission, Wade wants us to cut up human diversity into five races not because that's what the statistical analyses show but because thinking about it as a gradient is hard.
The technique is based on the phenomenon, that after applying pressure with the probe, soft tissues are compressed in a greater extent than hard tissues and the gradient values of strain are visualized on a color map.
They have concluded that the composition and the quantity of proteins existing in the hard corona vary between the gradient plasma media and non-gradient plasma media.
