Revision bibliográfica. Cuidados del catéter periférico

[ES]Los cateterismos venosos periféricos son los dispositivos que con mayor frecuencia se emplean en el acceso vascular para pacientes que se encuentran ingresados en unidades hospitalarias. Estos catéteres son reemplazados sistemáticamente cada tres o cuatro días para tratar de prevenir la flebitis como refleja la guía de Center for Disease control and prevention (CDC) y por extensión, nuestro sistema de salud de Osakidetza. Sin embargo, la evidencia que apoya esta práctica no está del todo cimentada.El objetivo de esta revisión bibliográfica es evaluar la efectividad de esta práctica clínica tan integrada en la vida diaria de los profesionales de enfermería mediante la evaluación de la evidencia científica existente hasta el momento.Se realizo una búsqueda exhaustiva en diferentes bases de datos electrónicas desde Octubre de 2012 hasta Abril del año 2013. Se descargaron los textos completos de aquellos artículos que pudiesen ser potencialmente útiles en el estudio y se analizaron bajo los criterios de inclusión y selección. Los siete artículos seleccionados como válidos no demuestran que sea necesario sustituir de forma sistemática el catéter venoso periférico así como lo defiende la CDC. Debido a ello, se podría abolir esta práctica clínica que reduciría significativamente el dolor y las molestias que sufren los pacientes día a día, el tiempo que el personal de enfermería dedica en este tipo de prácticas, además de todo el coste sanitario que ello con lleva.

Two-magnon bound state causes ultrafast thermally induced magnetisation switching

There has been much interest recently in the discovery of thermally induced magnetisation switching using femtosecond laser excitation, where a ferrimagnetic system can be switched deterministically without an applied magnetic field. Experimental results suggest that the reversal occurs due to intrinsic material properties, but so far the microscopic mechanism responsible for reversal has not been identified. Using computational and analytic methods we show that the switching is caused by the excitation of two-magnon bound states, the properties of which are dependent on material factors. This discovery allows us to accurately predict the onset of switching and the identification of this mechanism will allow new classes of materials to be identified or designed for memory devices in the THz regime.

Permutationally invariant state reconstruction

Feasible tomography schemes for large particle numbers must possess, besides an appropriate data acquisition protocol, an efficient way to reconstruct the density operator from the observed finite data set. Since state reconstruction typically requires the solution of a nonlinear large-scale optimization problem, this is a major challenge in the design of scalable tomography schemes. Here we present an efficient state reconstruction scheme for permutationally invariant quantum state tomography. It works for all common state-of-the-art reconstruction principles, including, in particular, maximum likelihood and least squares methods, which are the preferred choices in today's experiments. This high efficiency is achieved by greatly reducing the dimensionality of the problem employing a particular representation of permutationally invariant states known from spin coupling combined with convex optimization, which has clear advantages regarding speed, control and accuracy in comparison to commonly employed numerical routines. First prototype implementations easily allow reconstruction of a state of 20 qubits in a few minutes on a standard computer

Fault-tolerant almost exact state transmission

We show that a category of one-dimensional XY-type models may enable high-fidelity quantum state transmissions, regardless of details of coupling configurations. This observation leads to a fault-tolerant design of a state transmission setup. The setup is fault-tolerant, with specified thresholds, against engineering failures of coupling configurations, fabrication imperfections or defects, and even time-dependent noises. We propose an experimental implementation of the fault-tolerant scheme using hard-core bosons in one-dimensional optical lattices.
