RESULTS: The ATC provided consistently stable environmental and temperature control throughout extended cultures. Live imaging revealed dynamic endothelia with cells migrating throughout the vessel walls, both downstream (with) and upstream (against) the flow direction. Cell-cell junctions were contiguous, indicating a confluent, healthy endothelium with intact cytoskeletons. The cross-sectiona...

A series of lenses for focusing and collimating the output of semiconductor lasers is described. The description of an anamorphic prism pair to convert the beam cross-section from elliptical to circular is also given. Designs which perform to diffraction limitation yet lend themselves to low cost manufacturing are specifically considered. Correction for the aberrative effects of diode windows, ...

This paper introduces an experimental work to study the behavior of 12 recycled aggregate concrete-filled steel tubular (RACFST) short columns with high-strength concrete grade subjected axial compression loading. These formed from six different cross-sections involving triangle, elliptical, and hexagon, whereas other three sections included traditional forms for control purposes, square, recta...

A 2+1-dimensional anisentropic magnetogasdynamic system with a polytropic gas law is shown to admit an integrable elliptic vortex reduction when γ = 2 to a nonlinear dynamical subsystem with underlying integrable Hamiltonian–Ermakov structure. Exact solutions of the magnetogasdynamic system are thereby obtained which describe a rotating elliptic plasma cylinder. The semi-axes of the elliptical ...
