The dynamics of the histological changes which occur in the distal half of the tibial portion of the embryonic chick tibiotarsus from day 8 to day 18 of incubation are correlated with the capacities of histologically distinct zones to incorporate isotopic precursors into mucopolysaccharides and collagen. At the distal end of the tibia, which abuts the suture line formed by the fusion of the two...

Inspired by the layered hierarchical nano- and microstructures of natural nacre, flattened double-walled carbon nanotube (FDWCNT) reinforced epoxy composites are fabricated. Impressively, the prepared composites exhibit layered structures analogous to nacre, and the FDWCNT loading can reach 70 wt%, which results in superior mechanical properties that evidently outperform other existing materials.

A novel flattened ring resonator design utilizing Etched Beam Splitters (EBS) in InGaAsP/InP is proposed and demonstrated. A multiple-thickness hard mask that compensates for RIE-lag realizes waveguides and EBS gaps in a single etch step. ©2009 Optical Society of America OCIS codes: 230.5750 Resonators, 250.5300 Photonic integrated circuits

Mosaicing of images is the task of fusing a collection of images with smaller elds of view to obtain an image with a larger eld of view. In order to accomplish this task, images should be geometrically and radio-metrically corrected. We propose a new approach for perspective correction useful when smaller images are gathered by rotating a camera with a xed position. These images are projected o...

> The motion and shape of a flattened drop and bubble through another continuous liquid phase (conveying phase) are investigated experimentally, using a narrow gap HeleShaw cell. Seven different liquid-liqu...
