This invention provides modified rapamycins that have specific monosaccharide, oligosaccharide, pseudosugar or derivatives thereof attached through a linker to create rapamycin carbohydrate derivatives having enhanced pharmacokinetic andor pharmacodynamic profiles. The images may be graphics files or standard files with an associated thumbnail image. The first and second output transistors occupy an L-shaped area of the semiconductor die, the L-shaped area having first and second inner sides that are respectively disposed adjacent first and second sides of the control circuit. A memory element memorizes a state indicating a destination port being used for a multicast cellgroup, and a further memory element indicates a state requesting a generation of a multicast copy for a destination port, all according to a rule of exclusiveness. A data projector receives user markup data entered on various touch-sensitive tablets and projects the markup data onto a display surface as part of a collaborative drawing or image.
