Radio Emission AIRES: Results and parameterization

Radio emission has been implemented in the simulation software AIRES by M. A. DuVernois, B. Cai and D. Kleckner to perform a full Monte Carlo simulation of the radio emission of cosmic ray extensive air shower. Different sets of showers have been simulated. We present here the detendency of the radio electric field with different parameters (primary energy, radial distance, arrival direction, etc). We stress the effect of the polarization and the arrival direction, which should have a fundamental effect on the interpretation of experimental data.Comment: Contribution to the 31st International Cosmic Ray Conference, Lodz, Poland, July 2009. 4 pages, 7 figures. v2: Minor corrections: added arXiv dross reference, fixed typos, updated 1 figure, corrected one color scal

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Low-Cost Energy Consumption Monitoring System Using NodeMCU

Energy consumption in urban areas has experienced unprecedented growth. This shows the need to know the consumption in real-time to make efficient use. Therefore, this paper describes the development of a low-cost prototype for the acquisition of energy consumption data. A simple design has been proposed, using electronic components readily available in the local market. Measurements are made with an SCT013 electrical sensor placed around a conductor in the distribution box. The NodeMCU development board is a processing unit connecting several devices through data buses and WiFi. The script programming was done in c++ language using the Arduino IDE, while the mobile application for visualization was developed in Blynk. As a case study, real-time measurements and tests were carried out in a higher education center. A standard ammeter and multimeter were used for system calibration to ensure reliable and accurate results. During the experimental tests, an error of 2,839% was obtained compared to commercial equipment, which validates the use of this proposal. Linear regression is performed to propose an approximation model based on monthly consumption data for one year. With this average measurement, abnormal variations in monthly consumption can be identified, which could mean an electrical failure in the building. This type of proposal allows for better decision-making, proposes structural improvements, and is a basis for developing smarter cities

Data from: Effects of a systematically offered social and preventive medicine consultation on training and health attitudes of young people not in employment, education or training (NEETs): an interventional study in France

Background NEETs (young people not in employment, education or training) are at higher risk for poorer mental and physical health. In France, the Missions locales (MLs) are the only social structures dedicated to this population. We sought to determine whether the systematic offer of a social and preventive medicine consultation at a ML might increase NEET participants’ access to training in the 12 months following the intervention. Methods This intervention research was a parallel randomised controlled interventional study conducted at five MLs in mainland France in 2011-2012. It included 976 NEETs aged 18 to 25 years who attended one of the five MLs. At inclusion, participants were randomly assigned (1:1:1) to three groups: those in the first group were invited to see a social worker (not studied in this paper), those in the second group were invited to see a doctor and a social worker (intervention group), and the third was a control group. The primary outcome was participation in at least one training session during the year following study inclusion. Results Among the 976 participants, 504 were randomly assigned to the intervention group and 472 to the control group; 704 (72.1%) were included in the analyses. A significantly higher proportion of the participants in the intervention group participated in a training session in the 12 months following the intervention than of those in the control group (63.3% vs 55.6%; p=0.04). This difference was significantly greater for women, those less than 21 years of age, those unstably housed and those with a lower level of education. Conclusions Social and preventive medicine consultations that are fully integrated into the social services for NEETs have an impact on their access to training and contribute to changing some of their health-related behaviours. This may improve their access to the labour market

Feasibility and reliability of the Spondyloarthritis Research Consortium of Canada sacroiliac joint inflammation score in children

Abstract Background Published methods for quantification of magnetic resonance imaging (MRI) evidence of inflammation in the sacroiliac joint lack validation in pediatric populations. We evaluated the reliability and construct validity of the Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joint inflammation score (SIS) in children with suspected or confirmed juvenile spondyloarthritis (JSpA). Methods The SPARCC SIS measures the presence, depth, and intensity of bone marrow inflammation on MRI through the cartilaginous part of the joint. Six readers blinded to clinical details except age, participated in two reading exercises, each preceded by a calibration exercise. Inter-observer reliability was assessed using intraclass correlation coefficients (ICCs) and for pre-specified acceptable reliability the inraclass correlation coefficient (ICC) was > 0.8. Results The SPARCC SIS had face validity and was feasible to score in pediatric cases in both reading exercises. Cases were mostly male (64%) and the median age at the time of imaging was 14.9 years. After calibration, the median ICC across all readers for the SIS total score was 0.81 (IQR 0.71–0.89). SPARCC SIS had weak correlation with disease activity (DA) as measured by the JSpADA (r = − 0.12) but discriminated significantly between those with and without elevated C-reactive protein (p = 0.03). Conclusion The SPARCC SIS was feasible to score and had acceptable reliability in children. The ICC improved with additional calibration and reading exercises, for both experienced and inexperienced readers
