We have been considering the problem of designing a non-blocking network, i.e. a network in which we can simultaneously connect every input i to an output (i) where can be any permutation. We considered two candidates for this: the Butter y and the Benes. On the Butter y we saw that for some permutations it was indeed possible to make all N connections, where N is the number of inputs, but for ...

Chiral 3,3a,5,9b-tetrahydro-2H-furo[3,2-c][2]benzopyrans (TFBs) were synthesized and some of them were found to be herbicidally active against annual paddy weeds through intensive structure–activity relationship studies. These compounds were synthesized from D-glucose, which was used as a natural chiral source. This was the result of a series of studies based on the findings that certain benzyl...
