The Universidad del Valle de México or UVM is a private university founded in Mexico City in 1960. UVM enrolls students at several campuses throughout Mexico and offers undergraduate and graduate degrees in the fields of Medicine, Engineering, Business, and Law, among others. The institution has the highest accreditation level from the Mexican Department of Education and FIMPES accrediting board. UVM currently ranks in the top 16% of mexican universities, and top 8% of private mexican universities, according to the 2014 QS Latin America University rankings, accounting the 180 public and private universities which are members of ANUIES.

A quantum storage and state transference machine based on spin systems is considered. The process described cannot be regarded a a quantum teleportation because it does not involve any measurement. In previous work on quantum storage and state transference based on spin systems, exchange degeneracy was not taken into account and this is important because the initial and final states can become indistinguishable from each other and so the state transference may loose its meaning. It is shown that such a failure can be corrected by symmetrization. We conclude that in a consistent state transference and storage process, the parity of the initial state is not necessarily conserved. Source

Cerebral venous thrombosis (CVT) is a relatively rare form of stroke usually affecting young individuals. CVT is characterized by the diversity of its neurologic manifestations, which require a high level of clinical suspicion for diagnosis and prompt, appropriate treatment. Multiple circumstances have been associated with CVT, such as prior medical conditions, transient situations, certain medications, and some predisposing conditions. Headache, focal neurologic deficit, and seizures are the most frequent clinical manifestations at onset. MRI in combination with venography has become the imaging modality of choice, as this technique has a high sensitivity and specificity for establishing a diagnosis. CT venography is an alternative to MRI because this technique produces similar diagnostic results. Pharmacologic treatment of CVT with anticoagulants iswidely accepted. Per 100 cases, the recurrence of CVT is 2.8% and the mortality of CVT is 10%. © 2014 American Academy of Neurology. Source

Shannon entropy for the position and momentum eigenstates of the symmetrically trigonometric Rosen-Morse potential for the lower states n = 1-4 is evaluated. The position information entropies Sx for n = 1,2 are presented analytically. Some interesting features of the information entropy densities ρs(x) and ρs(p) are demonstrated graphically. We find that the ρs(p) is inversely proportional to the range of potential a and the Sx decreases with increasing the potential depth D. In particular, we note that the Sx might become negative for some given parameters a and D. The Bialynicki-Birula-Mycielski inequality is also tested for a number of states and is found to generally hold well. © 2013 The Royal Swedish Academy of Sciences. Source

The particle in a symmetrical squared tangent potential well is studied by examining its Shannon information entropy and standard deviations. The position and momentum information entropy densities ρs(x), ρs(p) and probability densities ρ(x), ρ(p) are illustrated with different potential range L and potential depth U. We present analytical position information entropies Sx for the lowest two states. We observe that the sum of position and momentum entropies Sx and Sp expressed by Bialynicki-Birula-Mycielski (BBM) inequality is satisfied. Some eigenstates exhibit entropy squeezing in the position. The entropy squeezing in position will be compensated by an increase in momentum entropy. We also note that the Sx increases with the potential range L, while decreases with the potential depth U. The variation of Sp is contrary to that of Sx. © 2013 Elsevier B.V. All rights reserved.

Shannon entropy for the position and momentum eigenstates of an asymmetric trigonometric Rosen-Morse potential for the ground and first excited states is evaluated. The position and momentum information entropies Sx and Sp are calculated numerically. Also, it is found that Sx1 is obtained analytically and increases with the potential depth and width. Some interesting features of the information entropy densities ρs(x) and ρs(p) are demonstrated graphically. The Bialynicki-Birula-Mycielski inequality is also tested and found to hold good.
