Una evidencia robusta de que el algoritmo DES fortalecido con una permutación inicial variable es eficiente

By using the JV Theorem, it is possible to associate a number of size 10 89 to a 64 position permutation in 63 steps. This result has been applied to strengthening the DES algorithm by using a variable initial permutation, increasing the computational complexity of the algorithm, given that each permutation works as a key. However, it still remains to be seen how the variable initial permutatio...

Beethoven (Muss es sein? Es muss sein!)

"The child is father of the man" is the philosophy of the paediatrician, hence the recent trend of intense interest in child development, which embraces the study of factors which influence the growth of the body, mind, personality and spirit from conception to maturity and ultimate achievement. As practitioners of medicine it is natural that much of our effort should be used in the diagnosis a...

Reanalyzing German Correlative Es

Several Germanic languages use correlatives to mark subordination. German is considered to be a prime example of a language realizing correlative constructions to embed finite argument clauses. This paper discusses complex clausal constructions in German that can be identified by a so-called correlative nominal element es (‘it’) and a right-peripheral full clausal argument that is linked to es....

Transport if loaded uclear transporters can be viewed as taxis that move cargo across the nuclear envelope. On page 649, Plafker et al. report that importin-11, a nuclear transport receptor , may be an especially selective cabbie. Importin-11 transports UbcM2, a ubiquitin (Ub)-conjugating enzyme, but it does so only when the enzyme is charged with a Ub at its active site. UbcM2 is an E2 enzyme,...
