How rare arable weeds are descriptors of low farming intensification?
International audience; Recent emphasis has been placed on the rapid destruction of the planet’s biodiversity in allhabitats. Rare arable weeds, also known as segetal plants, are threatened species, mostly indecline due to intensive farming systems. However, the presence of these species is intrinsicallylinked to agroecosystems. Their survival is apparently related to low-input agronomic practices.Could these weeds therefore be good descriptors of low agricultural intensification and be goodindicators of high environmental field value? We propose to examine the relationships between thefarming systems and weed flora sampling in the same fields.

Evidence for Muon Neutrino Oscillation in an Accelerator-Based Experiment
We present results for muon neutrino oscillation in the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment. K2K uses an accelerator-produced muon neutrino beam with a mean energy of 1.3 GeV directed at the Super-Kamiokande detector. We observed the energy dependent disappearance of muon neutrino, which we presume have oscillated to tau neutrino. The probability that we would observe these results if there is no neutrino oscillation is 0.0050% (4.0 sigma).

TRITIUM - A Real-Time Tritium Monitor System for Water Quality Surveillance
In this work the development results of the TRITIUM project is presented. The main objective of the project is the construction of a near real-time monitor for low activity tritium in water, aimed at in-situ surveillance and radiological protection of river water in the vicinity of nuclear power plants. The European Council Directive 2013/51/Euratom requires that the maximum level of tritium in water for human consumption to be lower than 100 Bq/L. Tritium levels in the cooling water of nuclear power plants in normal operation are much higher than the levels caused by the natural and cosmogenic components, and may easily surmount the limit required by the Directive. The current liquid-scint…
Measurement of neutrino oscillation by the K2K experiment
We present measurements of nu_mu disappearance in K2K, the KEK to Kamioka long-baseline neutrino oscillation experiment. One hundred and twelve beam-originated neutrino events are observed in the fiducial volume of Super-Kamiokande with an expectation of 158.1^{+9.2}_{-8.6} events without oscillation. A distortion of the energy spectrum is also seen in 58 single-ring muon-like events with reconstructed energies. The probability that the observations are explained by the expectation for no neutrino oscillation is 0.0015% (4.3sigma). In a two flavor oscillation scenario, the allowed Delta m^2 region at sin^2(2theta) is between 1.9 and 3.5 x 10^{-3} eV^2 at the 90% C.L. with a best-fit value o…
[Variables associated with disability in elderly bipolar patients on ambulatory treatment].
Introduction: Studies on adult bipolar patients have demonstrated a disability associated with the bipolar disorder, even in euthymic patients, but there is a lack of data in the elderly population. Material and method: A cross-sectional, multicentre study on a consecutive sample of ambulatory bipolar patients (DSM-IV-TR criteria), aged 65 years or over. Retrospective and cross-sectional sociodemographic and clinical data were collected, as well as the Clinical Global Impression for Bipolar Modified scale (CGI-BP-M) and the level of disability using the World Health Organisation Disability Assessment Schedule (WHO/DAS). The disability was assessed globally and by areas. The presence of a mo…
Discapacidad en pacientes bipolares ancianos en tratamiento ambulatorio. Variables asociadas
Resumen Introduccion Los estudios en pacientes bipolares adultos han demostrado una discapacidad asociada al trastorno bipolar, incluso en pacientes eutimicos, pero apenas hay datos en poblacion anciana. Material y metodo Estudio transversal y multicentrico, en una muestra de pacientes bipolares (criterios DSM-IV-TR) ambulatorios, consecutivos, con edad igual o superior a 65 anos. Se recogieron datos retrospectivos y transversales sociodemograficos y clinicos, ademas de la gravedad clinica global (ICG-BP-M) y el grado de discapacidad mediante la Escala de Discapacidad de la OMS (WHO/DAS). Se valoro la discapacidad global y por areas. Se considero variable dependiente la presencia de discapa…
Hierarchical Parallelization of an H.264/AVC Video Encoder
Last generation video encoding standards increase computing demands in order to reach the limits on compression efficiency. This is particularly the case of H.264/AVC specification that is gaining interest in industry. We are interested in applying parallel processing to H.264 encoders in order to fulfill the computation requirements imposed by stressing applications like video on demand, videoconference, live broadcast, etc. Given a delivered video quality and bit rate, the main complexity parameters are image resolution, frame rate and latency. These parameters can still be pushed forward in such a way that special purpose hardware solutions are not available. Parallel processing based on…
Characterization of a medium size Xe/TMA TPC instrumented with microbulk Micromegas, using low-energy gamma-rays
NEXT-MM is a general-purpose high pressure (10 bar, $\sim25$ l active volume) Xenon-based TPC, read out in charge mode with an 8 cm $\times$8 cm-segmented 700 cm$^2$ plane (1152 ch) of the latest microbulk-Micromegas technology. It has been recently commissioned at University of Zaragoza as part of the R&D of the NEXT $0\nu\beta\beta$ experiment, although the experiment's first stage is currently being built based on a SiPM/PMT-readout concept relying on electroluminescence. Around 2 million events were collected during the last months, stemming from the low energy $\gamma$-rays emitted by a $^{241}$Am source when interacting with the Xenon gas ($\epsilon$ = 26, 30, 59.5 keV). The localized…
A loss of status and a sense of defeat
This longitudinal study among Spanish teachers (N = 558) examined burnout from an evolutionary social rank perspective. The types of stress differed among various school levels, and a sense of defeat was highest among teachers in primary schools. A low status, a loss of status and a sense of defeat were independent cross‐sectional predictors of burnout. Longitudinally a sense of defeat predicted an increase in burnout over time, especially among males and teachers in high schools. The status related variables were in general more important predictors of burnout than stressors that are usually associated with burnout. Copyright © 2007 John Wiley & Sons, Ltd.
Search for coherent charged pion production in neutrino-carbon interactions
We report the result from a search for charged-current coherent pion production induced by muon neutrinos with a mean energy of 1.3 GeV. The data are collected with a fully active scintillator detector in the K2K long-baseline neutrino oscillation experiment. No evidence for coherent pion production is observed and an upper limit of $0.60 \times 10^{-2}$ is set on the cross section ratio of coherent pion production to the total charged-current interaction at 90% confidence level. This is the first experimental limit for coherent charged pion production in the energy region of a few GeV.
Assessment of the worldwide burden of critical illness: The Intensive Care Over Nations (ICON) audit
Item does not contain fulltext BACKGROUND: Global epidemiological data regarding outcomes for patients in intensive care units (ICUs) are scarce, but are important in understanding the worldwide burden of critical illness. We, therefore, did an international audit of ICU patients worldwide and assessed variations between hospitals and countries in terms of ICU mortality. METHODS: 730 participating centres in 84 countries prospectively collected data on all adult (>16 years) patients admitted to their ICU between May 8 and May 18, 2012, except those admitted for fewer than 24 h for routine postoperative monitoring. Participation was voluntary. Data were collected daily for a maximum of 28 da…
Measurement of inclusive pi(0) production in the charged-current interactions of neutrinos in a 1.3-GeV wide band beam
In this paper we report on the measurement of the rate of inclusive $\pi^0$ production induced by charged-current neutrino interactions in a C$_8$H$_8$ target at a mean energy of 1.3 GeV in the K2K near detector. Out of a sample of 11,606 charged current neutrino interactions, we select 479 $\pi^0$ events with two reconstructed photons. We find that the cross section for the inclusive $\pi^0$ production relative to the charged-current quasi-elastic cross section is $$\frac{\sigma_{CC\pi^0}}{\sigma_{CCQE}}=0.426\pm0.032(stat.)\pm0.035(syst.)$$ The energy dependent cross section ratio is also measured. The results are consistent with previous experiments for exclusive channels on different ta…
