Probing the ZZgamma and Zgammagamma Couplings Through the Process e+e- --> nu anti-nu gamma

We study the sensitivity for testing the anomalous triple gauge couplings $ZZ\gamma$ and $Z\gamma\gamma$ via the process $e^+e^-\to \nu \bar\nu \gamma$ at high energy linear colliders. For integrated luminosities of 500 $fb^{-1}$ and center of mass energies between 0.5 and 1.5 $TeV$, we find that this process can provide tests of the triple neutral gauge boson couplings of order $10^{-4}$, one order of magnitude lower than the standard model prediction.Comment: 12 pages, 6 figure

Aplicabilidad del test MABC en escolares con síndrome de down

El presente estudio analiza la aplicabilidad de tests de coordinación y habilidad motriz, diseñados para la población infantil general, en escolares de Educación Física Especial. Para el estudio se selecciona una muestra de niños y niñas con síndrome de Down, de 9 y 10 años, del colegio de educación especial ¿María Corredentora¿ de Madrid. Se utilizan las pruebas del Test MABC para el tramo de 4 a 6 años de edad (con algunas adaptaciones) y la escala de observación ECOMI tomada como criterio de validez. Resultados y conclusiones: El módulo de 4 a 6 años del test MABC es aplicable, con ligeras modificaciones, para evaluar las habilidades motrices fundamentales de niños y niñas con síndrome de Down. El conjunto de las pruebas muestra coeficientes de fiabilidad y validez adecuados. El grado de desarrollo motor de estos niños (9 y 10 años), mediante la comparación con el baremo de MABC, es inferior al promedio de la población española de escolares de 4 a 6 años

Management of wet age-related macular degeneration in Spain: challenges for treat and extend implementation in routine clinical practice

Age-related macular degeneration; Ophthalmology services; Anti-VEGFDegeneración macular relacionada con la edad; Servicios de oftalmología; Anti-VEGFDegeneració macular relacionada amb l’edat; Serveis d’oftalmologia; Anti-VEGFPurpose. To ascertain wet AMD (wAMD) management patterns in Spain. Methods. A two-round Delphi study conducted through a questionnaire-based survey designed from literature review and validated by an independent Steering Committee. Results. Forty-nine retina specialists experienced in wAMD participated by answering the two-round study questionnaire. Retina specialists are the main responsible for wAMD diagnosis and monitoring, including visits and associated procedures, with a median time per visit of 15 minutes. Standard treatment strategies are based on anti-VEGF administration, including standard loading dose administration followed by maintenance with aflibercept or ranibizumab (81% of patients). Although treat and extend (T&E) dosing strategy is considered as optimal for wAMD management (78% of the panelists), the main routine healthcare limitations (i.e., visits overload, reduced staff, short visit time, coordination issues, lack of facilities) conduct to self-defined “flexible” strategies, based on T&E and pro-re-nata (PRN) protocols. Conclusion. Proactive treatment patterns (T&E) are the preferred ones by the retina specialists in Spain. However, their proper implementation is difficult due to healthcare resource limitations, as well as organisation and logistic issues. The use of anti-VEGF agents with longer duration of action could facilitate the use of strict T&E approaches according to routine clinical practices

A search for pre- and proto-brown dwarfs in the dark cloud Barnard 30 with ALMA

In this work we present ALMA continuum observations at 880 $\mu$m of 30 sub-mm cores previously identified with APEX/LABOCA at 870$\mu$m in the Barnard 30 cloud. The main goal is to characterize the youngest and lowest mass population in the cloud. As a result, we report the detection of five (out of 30) spatially unresolved sources with ALMA, with estimated masses between 0.9 and 67 M$_{\rm Jup}$. From these five sources, only two show gas emission. The analysis of multi-wavelength photometry from these two objects, namely B30-LB14 and B30-LB19, is consistent with one Class II- and one Class I low-mass stellar object, respectively. The gas emission is consistent with a rotating disk in the case of B30-LB14, and with an oblate rotating envelope with infall signatures in the case of LB19. The remaining three ALMA detections do not have infrared counterparts and can be classified as either deeply embedded objects or as starless cores if B30 members. In the former case, two of them (LB08 and LB31) show internal luminosity upper limits consistent with Very Low Luminosity objects, while we do not have enough information for LB10. In the starless core scenario, and taking into account the estimated masses from ALMA and the APEX/LABOCA cores, we estimate final masses for the central objects in the substellar domain, so they could be classified as pre-BD core candidates.Comment: Published in A&

Limits on the Dipole Moments of the τ\tau-Lepton via the Process $e^{+}e^{-}\to \tau^+ \tau^- \gamma in a Left-Right Symmetric Model

Limits on the anomalous magnetic moment and the electric dipole moment of the $\tau$ lepton are calculated through the reaction $e^{+}e^{-}\to \tau^+ \tau^- \gamma$ at the $Z_1$-pole and in the framework of a left-right symmetric model. The results are based on the recent data reported by the L3 Collaboration at CERN LEP. Due to the stringent limit of the model mixing angle $\phi$, the effect of this angle on the dipole moments is quite small.Comment: 15 pages, 3 figure

Fuzzy Controller for Automatic Steering in Heavy Vehicle Semi-Trailers

AbstractTrucks with semi-trailers are widely used for transportation of goods due their low operation cost, but inherent to these vehicles are some problems such as a poor maneuverability. To minimize the effects of this disadvantage, among other solutions, the incorporation of steerable axles in the semitrailers has been proposed. This paper presents a steering equation, and a fuzzy-logic controller for a semi-trailer automatic forced-steering system to minimize the off-tracking and the total swept path width, resulting in an improvement of vehicle's maneuverability at low speeds. To accomplish this, the suggested control algorithm considers the articulation angle and parameters such as vehicle speed and direction. The system was tested on an instrumented experimental semi-trailer during various predetermined test maneuvers

Impact exercise strategies in the HRQOL of the sedentary adults

El objetivo del estudio fue analizar la eficacia de diferentes estrategias de intervención del ejercicio físico y relacionarlas con la percepción de la calidad de vida relacionada con la salud (CVRS) en adultos mayores sedentarios. Participaron 100 sujetos, con edades comprendidas entre los 60 y 70 años, que fueron divididos aleatoriamente en cuatro grupos: control, recomendación, prescripción y monitorización. La intervención de ejercicio físico tuvo una duración de 6 meses. Para la valoración de la CVRS se utilizó el cuestionario SF-36. Los grupos monitorización y prescripción obtuvieron los mayores valores en todos los dominios en el análisis intragrupos. La función física y la salud general y mental obtienen los mayores valores significativos entre grupos (p<.05). Entre los grupos prescripción y monitorización no existen diferencias significativas en ninguna dimensión. Sin embargo el grupo de monitorización obtuvo valores superiores en salud mental, no siendo así en salud físicaThe aim of the study was to analyze the effectiveness of different intervention strategies of exercise and relate the perception of quality of life related to health (HRQOL) in sedentary older adults. It involved 100 subjects, aged between 60 and 70, who were randomly divided into four groups: control, recommend, prescribe and monitor. The exercise intervention lasted 6 months. The SF-36 questionnaire was used for the assessment of HRQOL. The monitoring and prescription groups had higher values in all domains in the intragroup analysis. Physical function and health and mental health obtain the highest significant values between groups (p <.05). There are no significant differences at all in any domain among prescription and monitoring groups. However, the monitoring group obtained higher values in mental health, but were not in physical healt

Classification of uterine anomalies by three-dimensional ultrasonography using ESHRE/ESGE criteria: inter-observer variability.

Objective: To evaluate the interobserver repeatability of the coronal view measurements and classification of the uterine malformations (UM) according to the ESHRE/ESGE consensus by transvaginal three-dimensional ultrasound (3D US). Methods: 89 transvaginal 3D volumes acquired during the last two years at Delta Ecografía in Madrid, Spain, were selected from our archive by convenience sampling. Two expert operators blinded from each other, performed post-hoc analysis using render mode and multiplanar-VCI navigation. Uterine wall thickness at the fundus, indentation of the cavity and indentation of the fundus were measured, classified and sub-classified following the recommendations of the ESHRE/ESGE consensus. The reproducibility of interobserver measurements and classification was examined by calculating intraclass correlation coefficients (ICC) and their 95% confidence intervals (CI) and kappa statistic (k).pre-print261 K
