A case of a 76-year-old man presenting with weakness of the lower legs and bilateral steppage gait is described. Neurological examination revealed a sensorimotor neuropathy with axonopathy and myelinic aspects. At the time of the diagnostic workup an episode of rectal bleeding occurred.

Despite their fundamental relevance, however, previous experiments did not consider an ingredient of relevance for quantum networks: the fact that correlations between(More)
This thesis focuses on the measurement of dissimilarity in the distribution of relevant<lb>economic attributes and inequality of opportunity. Equality of opportunity has gained popularity<lb>for defining the relevant equalitarian objective for the distribution of a broad range of social and<lb>economic outcomes among social groups.
