Sin embargo, se sabe que esta depende de la técnica quirúrgica y de las complicaciones postoperatorias, que ocurren hasta en un 28% de los casos24, 25, por lo que la respuesta a la derivación ventricular no puede considerarse como una prueba de referencia reproducible. En este contexto...

K. Gdel [G1] published his exact solution to Einstein's field equations in 1949. On the other hand, a general Lorentz invariant operator, associated to the so-called "relativistic diffusion? and making sense in any Lorentz manifold, was introduced recently by Franchi-Le Jan in [F-LJ]. ...
In addition to the packagesre,bs4,requests,operator,collections,heapq,stringandnltk, we will use the following. spaCy: Please set it up as given in theInstall spaCy docs. spaCy will help us do some quick NLP. We could use NLTK but spaCy will get you going faster. We use spaCy in this...
