N ov 1 99 8 Must Quantum Spacetimes Be Euclidean ?
The Bohm-de Broglie interpretation of quantum mechanics is applied to canonical quantum cosmology. It is shown that, irrespective of any regularization or choice of factor ordering of the Wheeler-DeWitt equation, the unique relevant quantum effect which does not break spacetime is the change of its signature from lorentzian to euclidean. The other quantum effects are either trivial or break the...

متن کاملExperiments testing macroscopic quantum superpositions must be slow
We consider a thought experiment where the preparation of a macroscopically massive or charged particle in a quantum superposition and the associated dynamics of a distant test particle apparently allow for superluminal communication. We give a solution to the paradox which is based on the following fundamental principle: any local experiment, discriminating a coherent superposition from an inc...

The Colombian Association of Psychiatry continues to work in different areas (professional and scientific issues) with the aim of improving the profession for its members. As you will have noted, from the scientific standpoint, the journal, as a means of communicating the knowledge base generated by mental health professionals, both national and international, strives for continued improvement ...
متن کاملTracheostomy must be individualized!
Tracheostomy is one of the most frequent procedures carried out in critically ill patients with major advantages compared to translaryngeal endotracheal intubation such as reduced laryngeal anatomical alterations, reduced inspiratory load, better patient's tolerance and nursing. Thus, tracheostomy can enhance patient's care in patients who need prolonged mechanical ventilation and/or control of...
