Systems and methods for data transport, including receiving one or more signals into a reconfigurable and flexible rate shared rate multi-transponder network architecture, wherein the network architecture includes one or more transponders with multiple line side interfaces and one or more client side interfaces. There is also an electrically conducting carrier substrate with a first surface and a second surface. Therefore, the crystallization process is performed using the capping layer pattern containing the metal catalyst, which has concentration and distribution varying depending on the thickness of the capping layer pattern, thereby improving the size and uniformity of grains. The board book has an expandable spine, which increases its size or thickness from its smaller empty size to its larger, filled size when filled with compact discs. A second contact electrically contacts the layer of second conductivity type. The present invention also relates to a non-destructive inspection apparatus of pearl quality.
