It operates partially in the training and encoding phases by normalizing the bandwidth covered by each split. The action is completed in the decoding phase by renormalizing the bandwidth spanned by each split of

The presence of the trimethylsilyl group in the triple bond favors the Prins cyclization and minimizes the 2-oxonia-[3,3]-sigmatropic rearrangement as a competitive alternative pathway. Ab initio theoretical calculations of the species involved in the rearrangements support the proposed mechanism. The process is highly stereoselective, affording cis-dihydropyran as the only isomer.

In the case of China, a prime example of the Asiatic mode of production, Marx even doubted whether globalization (capitalism) would ever be able to accomplish its historical mission of developing the forces of production and creating the material conditions for a higher mode of production, viz., communism. In the Russian case, he seriously entertained the notion that it could bypass the hardships and vicissitudes of capitalism and forge its own unique path to socialism. If accepted, this interpretation represents a serious challenge to the universality and validity of Marx’s materialist conception of history.
