We present a new multiscale approach for deformable contour optimization. The method relies on a multigrid minimization method and a coarse-to-®ne relaxation algorithm. This approach consists in minimizing a cascade of optimization problems of reduced and increasing complexity instead of considering the minimization problem on the full and original con®guration space. Contrary to classical mult...

We investigate the mechanism of aggregation of red blood cells (RBC) in capillary vessels. We use a discrete-particle model in 3D to model the flow of plasma and RBCs within a capillary tube. This model can accurately capture the scales from 0.001 to 100 μm, far below the scales that can be modeled numerically with classical computational fluid dynamics. The flexible viscoelastic red blood cell...

The concept of Virtual Paths (VP) is a powerful technique to improve the transmission efficiency in ATM networks. Transmission efficiency can be improved by dynamically changing the bandwidths of the VPs, based on the demand. Intelligent controllers, which predict bandwidth-demand patterns to enable better VP management, have the potential to revolutionize ATM network performance. We present a ...

Several brightness illusions indicate that borders can dramatically affect the perception of adjoining surfaces. In the Craik–O’Brien–Cornsweet illusion, in particular, two equiluminant surfaces can appear different in brightness due to the contrast border between them. Although the psychophysical nature of this phenomenon has been well characterized, the neural circuitry underlying this effect...

Changes in the lysosomes of senescent tissues and organisms are common and have been used as biomarkers of aging. Lysosomes are responsible for the degradation of many macromolecules, including proteins. At least five different pathways for the delivery of substrate proteins to lysosomes are known. Three of these pathways decline with age, and the molecular explanations for these deficiencies a...
