Contingency tables: developing virtual teaching materials

En la actualidad encontramos numerosas herramientas didácticas en Internet, sin embargo su utilidad potencial depende de los conocimientos que proporcionan y su uso por parte del profesor. En este trabajo, se describe un curso desarrollado para la enseñanza de las tablas de contingencia y los conceptos y procedimientos relacionados, en particular la asociación y la independencia, la prueba Chi cuadrado y algunos coeficientes de asociación. Este curso ha sido experimentado en asignaturas de la licenciatura de Psicología

OpenFlow compatible key-based routing protocol: adapting SDN networks to content/service-centric paradigm

The host-to-host/content/service communication instead of the host-to-host communication offered by traditional Internet Protocol (IP) routing solutions has been demanded in the last few years. Nowadays, getting this type of communication directly at network level is an increasing demand in the framework of new networking scenarios, such as Internet of Things and data center scenarios. Inspired by Key-Based Routing (KBR) solutions which, in conjunction with Distributed Hash Tables, have offered a way of providing content-sharing solutions in overlay networks on the top of the Internet for years now, we propose OFC-KBR (OpenFlow Compatible Key-Based Routing) solution. OFC-KBR is a key-based routing solution directly implemented at network layer that makes use of the potential of Software Defined Networking. In this solution, end-points are identified by virtual identifiers. These virtual identifiers are obtained from a descriptive textual name, whose format is not fixed and can be defined depending on the requirements of the service that is going to use the proposed OFC-KBR solution. OFC-KBR is totally compatible with the current OpenFlow standard and can co-exist with other L2/L3 protocols. The proposal has been implemented and evaluated by simulation considering real topologies.This research has been supported by the AEI/FEDER, UE Project Grant TEC2016-76465-C2-1-R (AIM).

Consistencia y fluctuación de los estados de ánimo en un equipo de fútbol profesional durante una competición de play off

The purpose of this paper is to describe a football team's mood processes during competitions through the administration of specific measures. A second division (level B) Spanish football team (Rayo Vallecano SAD, Madrid, Spain) was evaluated by means of the short Spanish version (15 items, Fuentes, García-Merita, Meliá and Balaguer, 1995) of the Profile of Mood State (POMS, MacNair, Lorr and Droppelmann, 1971), four times during the play-off phase (after the end of the regular season) to move on to a higher level during the 2006-07 Spanish Professional Soccer League season (level 2A). The results showed the absence of significant differences in the scores on the POMS' five scales (Depression, Vigour, Anger, Fatigue and Tension) recorded before the four play-off matches, meaning the existence of a consistency in the team's mood states during the whole phase of the play-off and the absence of significant fluctuations in mood mediumlasting processes. Despite that, the POMS' graphic averages displayed several patterns related to different scales. We suggest that the proposed method is useful in studying athletes' and teams' cognitive-emotional processes during specific types of ongoing competitions, as they ensure high ecological validity and provide information for more effective interventions tailor-made for teams

Congenital antithrombin deficiency in patients with splanchnic vein thrombosis

Splanchnic vein thromboses (SVT) are a rare condition that can be life-threatening. The most severe thrombophilia associated to SVT is antithrombin (AT) deficiency, usually caused by SERPINC1 mutations. Although transitory AT deficiencies and congenital disorders of the N-glycosylation pathways (CDG) have been recently reported as causes of AT deficiency, the current AT clinical screening still only includes anti-FXa activity. This study aims to 1) improve the detection of antithrombin deficiency in SVT and 2) characterize the features of antithrombin deficiency associated with SVT.The study was performed in 2 cohorts: 1) 89 SVT patients with different underlying etiologies but in whom AT deficiency had been ruled out by classical diagnostic methods; and 2) 271 unrelated patients with confirmed AT deficiency and venous thrombosis. Antithrombin was evaluated by functional (anti-FXa and anti-FIIa) and immunological methods (ELISA, crossed immunoelectrophoresis, western blot), and SERPINC1 sequencing was performed.In 4/89 patients (4.5%) additional alterations in AT were found (two had SERPINC1 mutations, one had a specific variant causing transient AT deficiency and one patient had CDG). In 11 of the 271 patients (4.1%) with AT deficiency and thrombosis, thrombosis was located at the splanchnic venous territory.AT deficiency may be underdiagnosed by current clinical screening techniques. Therefore, a comprehensive AT evaluation should be considered in cases of rethrombosis or doubtful interpretation of anti-FXa activity levels. SVT is a relatively common localization of the thrombotic event in patients with congenital AT deficiency.© 2019 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd

Ponderomotive Control of Quantum Macroscopic Coherence

It is shown that because of the radiation pressure a Schr\"odinger cat state can be generated in a resonator with oscillating wall. The optomechanical control of quantum macroscopic coherence and its detection is taken into account introducing new cat states. The effects due to the environmental couplings with this nonlinear system are considered developing an operator perturbation procedure to solve the master equation for the field mode density operator.Comment: Latex,22 pages,accepted by Phys.Rev.

La Hispania del Nuevo Mundo. Historia indiana y dinámicas políticas en el reinado de Felipe III

In Philip III’s reign, the field of textual representation from the Indies entered a period of renewed analysis that fueled discussions and political practices of implications of the Americas. This paper analyzes how the construction of the Indies’ past was actively involved in the discursive fields of the early seventeenth century as a political weapon.En el reinado de Felipe III el ámbito de representaciones textuales indianas conoció un tiempo de análisis renovados que alimentaron las discusiones y las prácticas políticas de implicaciones americanas. En el presente artículo se analiza cómo la construcción de la historia de América participó activamente en los ámbitos discursivos de comienzos del siglo XVII como arma política

Creating Metastable Schrodinger Cat States

We propose a scheme using feedback to generate a macroscopic quantum superposition of coherent states in an optical cavity mode which experiences very little decoherence (due to dissipation)

Ion irradiation effects in nonmetals: formation of nanocrystals and novel microstructures

Ion implantation is a versatile and powerful technique for producing nanocrystal precipitates embedded in the near-surface region of materials. Radiation effects that occur during the implantation process can lead to complex microstructures and particle size distributions, and in the present work, we focus on the application of these effects to produce novel microstructural properties for insulating or semiconducting nanocrystals formed in optical host materials. Nanocrystal precipitates can be produced in two ways: by irradiation of pure ( i.e. , non-implanted) crystalline or amorphous materials, or by ion implantation followed by either thermal annealing or subsequent additional irradiation. Different methods for the formation of novel structural relationships between embedded nanocrystals and their hosts have been developed, and the results presented here demonstrate the general flexibility of ion implantation and irradiation techniques for producing unique near-surface nanocomposite microstructures in irradiated host materials.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42336/1/10019-3-4-190_00030190.pd
