Photoelectron spectroscopy study of MC ( M 5 Sc , Y , and La , n

2 Photoelectron spectra of metal-attached carbon cluster anions MC (M5Sc, Y, and La, 5#n#20) generated in a n laser-vaporization ion source were measured using a magnetic bottle time-of-fligh photoelectron spectrometer with 6.4 eV photon energy. The vertical detachment energy (vDE) of each species was estimated from the spectra and compared with the 2 vDE of the linear and monocyclic ring forms...

La creatividad y la psicopatología

What is the relation between creativity and psychopathology? Does psychopathology facilitate creativity? Does creative activity induce psychopathology? We expose here an historical bibliographic review, in search of responses to these questions posed from ancient Greece to these days. For Plato, talent was the enthusiasm which drags one away from oneself. For Aristotle, creativity was a rationa...

Powers of R-diagonal Elements

We prove that if (a; b) is an R-diagonal pair in some non-commutative probability space (A; ') then (a p ; b p) is R-diagonal too and we compute the determining series f (a p ;b p) in terms of the distribution of ab. We give estimates of the upper and lower bounds of the support of free multiplicative convolution of probability measures compactly supported on 0; 1, and use the results to give n...

La maquinaria de computación y la inteligencia

Many mathematicians would agree that, had it not been for symmetric encryption, the improvement of context-free grammar might never have occurred. In our research, we confirm the exploration of Moore’s Law, which embodies the natural principles of complexity theory. ANTIAR, our new system for collaborative algorithms, is the solution to all of these obstacles.
