Fermionic entanglement ambiguity in non-inertial frames

We analyse an ambiguity in previous works on entanglement of fermionic fields in non-inertial frames. This ambiguity, related to the anticommutation properties of field operators, leads to non-unique results when computing entanglement measures for the same state. We show that the ambiguity disappears when we introduce detectors, which are in any case necessary as a means to probe the field entanglement.Comment: 9 pages, 4 figures.

Fermionic entanglement extinction in non-inertial frames

We study families of fermionic field states in non-inertial frames which show no entanglement survival in the infinite acceleration limit. We generalise some recent results where some particular examples of such states where found. We analyse the abundance and characteristics of the states showing this behaviour and discuss its relation with the statistics of the field. We also consider the phenomenon beyond the single mode approximation.Comment: 6 pages, 4 figures, revtex4-

Rectal Metastases from Squamous Cell Carcinoma: A Case Report and Review of the Literature

Non-small-cell lung cancer (NSCLC) represents 85% of lung cancer. The most frequent sites of distant metastasis are the liver, adrenal glands, bones and brain. Gastrointestinal metastases are uncommon and rectal metastases are extremely rare. Here we report a case of squamous cell carcinoma of the lung with rectal metastases

Teleportation of Accelerated Information

A theoretical quantum teleportation protocal is suggested to teleport accelerated and non-accelerated information over different classes of accelerated quantum channels. For the accelerated information, it is shown that the fidelity of the teleported state increases as the entanglement of the initial quantum channel increases. However as the difference between the accelerated channel and the accelerated information decreases the fidelity increases. The fidelity of the non accelerated information increases as the entanglement of the initial quantum channel increases, while the accelerations of the quantum channel has a little effect. The possibility of sending quantum information over accelerated quantum channels is much better than sending classical information

Kinetic study of the hydrodechlorination of chloromethanes with activated-carbon-supported metallic catalysts

This document is the unedited author's version of a Submitted Work that was subsequently accepted for publication in Industrial and Engineering Chemistry Research, copyright © American Chemical Society after peer review. To access the final edited and published work, see http://pubs.acs.org/doi/abs/10.1021/ie5042484The kinetics of the hydrodechlorination (HDC) of dichloromethane (DCM) and chloroform (TCM) with Pd, Pt, Rh, and Ru on activated carbon catalysts has been studied at temperatures between 100 and 250 °C. Different kinetic models have been checked, namely, pseudo-first-order and Langmuir-Hinshelwood-Hougen-Watson (LHHW) with adsorption, chemical reaction, or desorption control. The HDC of DCM and TCM with the Pd and Pt catalysts was well-described by the LHHW model with reactant adsorption as the rate-controlling step. However, with Rh and Ru catalysts, chemical reaction and desorption of the reaction products appear to be the rate-controlling steps in the HDC of DCM and TCM, respectively. In this last case, different sets of complex reactions seem to occur on the surface of the catalyst depending on the temperature, preventing determination of a confident value of the activation energy, because of the formation of oligomeric coke-like deposits and the subsequent severe deactivation of these catalysts. The corresponding kinetic parameters for the proposed models have been calculatedThe authors gratefully acknowledge financial support from the Spanish Ministerio de Economía y Competitividad (MINECO) through the project CTM2011-28352.

The Broad Concept of "Spasticity-Plus Syndrome" in Multiple Sclerosis: A Possible New Concept in the Management of Multiple Sclerosis Symptoms

Multiple sclerosis (MS) pathology progressively affects multiple central nervous system (CNS) areas. Due to this fact, MS produces a wide array of symptoms. Symptomatic therapy of one MS symptom can cause or worsen other unwanted symptoms (anticholinergics used for bladder dysfunction produce impairment of cognition, many MS drugs produce erectile dysfunction, etc.). Appropriate symptomatic therapy is an unmet need. Several important functions/symptoms (muscle tone, sleep, bladder, pain) are mediated, in great part, in the brainstem. Cannabinoid receptors are distributed throughout the CNS irregularly: There is an accumulation of CB1 and CB2 receptors in the brainstem. Nabiximols (a combination of THC and CBD oromucosal spray) interact with both CB1 and CB2 receptors. In several clinical trials with Nabiximols for MS spasticity, the investigators report improvement not only in spasticity itself, but also in several functions/symptoms mentioned before (spasms, cramps, pain, gait, sleep, bladder function, fatigue, and possibly tremor). We can conceptualize and, therefore, hypothesize, through this indirect information, that it could be considered the existence of a broad "Spasticity-Plus Syndrome" that involves, a cluster of symptoms apart from spasticity itself, the rest of the mentioned functions/symptoms, probably because they are interlinked after the increase of muscle tone and mediated, at least in part, in the same or close areas of the brainstem. If this holds true, there exists the possibility to treat several spasticity-related symptoms induced by MS pathology with a single therapy, which would permit to avoid the unnecessary adverse effects produced by polytherapy. This would result in an important advance in the symptomatic management of MS
