The present invention relates to therapeutically active cubane compounds, a method of preparing the same, and to pharmaceutical compositions comprising the compounds. For example, a video encoder adaptively switches between 8\xd78, 8\xd74, and 4\xd78 DCTs when encoding 8\xd78 prediction residual blocks; a corresponding video decoder switches between 8\xd78, 8\xd74, and 4\xd78 inverse DCTs during decoding. The apparatus can include a power tong assembly pivotally attached to the swing arm assembly. A linker is configured to store all the labeled portions of critical code into an Executable and Linking Format section header, which is relocated at run-time into a memory space reserved for the portions of critical code.
