Computation of Eigenstresses in Three-Dimensional Patient-Specific Arterial Walls

Residual stresses are present in a number of soft tissues. In the case of arterial walls they are supposed to be responsible for a smoothed circumferential stress gradient in radial direction. In the recent past, several publications dealt with residual stresses based on a multiplicative split of the deformation gradient using a cylindrical coordinate system, cf. for example [1], [2] and [3] an...

Antiviral walls

Repairing for death he targets of cytotoxic T lymphocytes (CTLs) determine their own mode of death, say Dennis Keefe, Judy Lieberman, and colleagues (Harvard Medical School, Boston, MA). The dying cells patch themselves up so that rapid and messy necrosis is avoided in favor of a more lengthy and controlled apoptosis. The CTLs deliver their insult in the form of perforin, a pore-forming protein...

Treatment Walls

The GroundWater Remediation Technologies Analysis Center (GWRTAC) is a national environmental technology transfer center that provides information on the use of innovative technologies to clean-up contaminated groundwater. Established in 1995, GWRTAC is operated by the National Environmental Technology Applications Center (NETAC) in association with the University of Pittsburgh's Environmental ...

Weightless Walls

In this paper we describe how future office environments can benefit from the addition of weightless walls—virtual, sound blocking walls created using headsets. We particularly focus on exploring how different interaction techniques can be employed to efficiently create, erase, or edit the layouts of these walls, and envisioning how they could impact the overall office experience.
