Additionally, fabrication is much simpler and more robust than typical gradient-forming systems due to the low viscosity of the microsphere solutions compared to gelating solutions, which can easily result in premature gelation or the trapping of air bubbles with a nerve guidance conduit.
This is most likely because instead of using finite difference approximation of the gradient in the optimization problem, we utilize sensitivity equations, yielding a more robust calculation of the gradient, which also seems to influence the precision of parameter estimates.
Feature detection on these sets individually yields more consistent gradient estimates and allows more robust photon constraints.
Gradient descent is therefore a more robust and computationally simple solution.
76 The north-to-south gradient for CD appears to be more robust than that for UC.
However, the measurement of gradients across coronary stenoses is inherently more robust than evaluation of opacification difference.
For absolute error loss L y, F =| y− F| the negative gradient is the sign of the residual making it more robust to skewed outcomes than the squared error loss function.
A more robust formation mechanism is the Biermann battery (Biermann 1950), which requires the density gradient in an ionized gas to be misaligned with the pressure gradient, and is thus coupled to the vorticity of the gas.
Using an engineered transcriptional repressor gradient, we demonstrate that overlapping repressor and activator binding sites provide more robust repression and sharper expression boundaries than non-overlapping sites.
The microglia of the white matter show more robust changes than those of grey matter and there is evidence of a rostro-caudal gradient in the magnitude of these changes.
