Magnetic fields inferred by Solar Orbiter: A comparison between SO/PHI-HRT and SDO/HMI

Context. The High Resolution Telescope (HRT) of the Polarimetric and Helioseismic Imager on board the Solar Orbiter spacecraft (SO/PHI) and the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) both infer the photospheric magnetic field from polarised light images. SO/PHI is the first magnetograph to move out of the Sun–Earth line and will provide unprecedented access to the Sun’s poles. This provides excellent opportunities for new research wherein the magnetic field maps from both instruments are used simultaneously. Aims. We aim to compare the magnetic field maps from these two instruments and discuss any possible differences between them. Methods. We used data from both instruments obtained during Solar Orbiter’s inferior conjunction on 7 March 2022. The HRT data were additionally treated for geometric distortion and degraded to the same resolution as HMI. The HMI data were re-projected to correct for the 3° separation between the two observatories. Results. SO/PHI-HRT and HMI produce remarkably similar line-of-sight magnetograms, with a slope coefficient of 0.97, an offset below 1 G, and a Pearson correlation coefficient of 0.97. However, SO/PHI-HRT infers weaker line-of-sight fields for the strongest fields. As for the vector magnetic field, SO/PHI-HRT was compared to both the 720-second and 90-second HMI vector magnetic field: SO/PHI-HRT has a closer alignment with the 90-second HMI vector. In the weak signal regime (< 600 G), SO/PHI-HRT measures stronger and more horizontal fields than HMI, very likely due to the greater noise in the SO/PHI-HRT data. In the strong field regime (≳600 G), HRT infers lower field strengths but with similar inclinations (a slope of 0.92) and azimuths (a slope of 1.02). The slope values are from the comparison with the HMI 90-second vector. Possible reasons for the differences found between SO/PHI-HRT and HMI magnetic field parameters are discussed.Sección Deptal. de Óptica (Óptica)Fac. de Óptica y OptometríaTRUEBMWi - Bundesministerium für Wirtschaft und Energie (Alemania)AEI/MCIN/10.13039/501100011033Ministerio de ciencia e innovación de EspañaInstituto Astrofísico de Andalucía (España)Agencia Estatal de Investigación (España)Fondo Europeo de Desarrollo Regional (Fondos FEDER)Centre national d'études spatiales (CNES) (Francia)CSIC (Centro Superior de Investigaciones Científicas) (España)pu

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

TALLER EXPERIMENTAL I MATERIA Y ESPACIO

El Taller Experimental I Materia y Espacio surge como propuesta docente de la CÁTEDRA BLANCA, dentro del Departamento de Proyectos Arquitectónicos, para los alumnos recién ingresados en la ETSAM.Durante el primer semestre se les introduce en la arquitectura apoyándose en el hormigón como material de proyecto. Es este material, donado por CEMEX, el que articula el aprendizaje del alumno.Individualmente y en grupo, diseñarán y ejecutarán sus propios encofrados,que se convertirán en objeto de diferentes investigaciones guiadas por los profesores.El empleo del hormigón no sólo aporta el conocimiento de las ideas que hay tras buena parte de la arquitectura moderna, que los alumnos empiezan a conocer. También se convierte en un argumento práctico que los involucra: ejercitando su visión espacial para representar y construir el negativo de la pieza deseada, despertando su curiosidad por cómo estos materiales de encofrado pueden transferir sus cualidades al hormigón y cómo condicionan el hormigonado y el desencofrado, pero, sobre todo, haciéndolos conscientes de que la arquitectura está tanto en la técnica que resuelve estos problemas como en la poética que ordena estas acciones, y que ambos aspectos son necesarios e inseparables.Con esta directriz, el curso se articula en torno a tres ejercicios, que se complementan con trabajos y presentaciones en grupo y visitas a arquitecturas en hormigón

The on-ground data reduction and calibration pipeline for SO/PHI-HRT

The ESA/NASA Solar Orbiter space mission has been successfully launched in February 2020. Onboard is the Polarimetric and Helioseismic Imager (SO/PHI), which has two telescopes, a High Resolution Telescope (HRT) and the Full Disc Telescope (FDT). The instrument is designed to infer the photospheric magnetic field and line-of-sight velocity through differential imaging of the polarised light emitted by the Sun. It calculates the full Stokes vector at 6 wavelength positions at the Fe I 617.3 nm absorption line. Due to telemetry constraints, the instrument nominally processes these Stokes profiles onboard, however when telemetry is available, the raw images are downlinked and reduced on ground. Here the architecture of the on-ground pipeline for HRT is presented, which also offers additional corrections not currently available on board the instrument. The pipeline can reduce raw images to the full Stokes vector with a polarimetric sensitivity of 10−3⋅Ic or better.Sección Deptal. de Óptica (Óptica)Fac. de Óptica y OptometríaTRUEBMWi - Bundesministerium für Wirtschaft und Energie (Alemania)MPG - Max-Planck-Gesellschaft (Alemania)Ministerio de Ciencia e Innovación de España - MCIUInstituto de Astrofísica de Andalucía - CSIC (España)CNES - Centre National d'études spatiales (Francia)Fondos FEDERAgencia Estatal de Investigación - AEI (ESpaña)pu

Aps Sustainable and Inclusive Social Volunteering: learning by doing a service stop the community (II)

El objetivo principal es consolidar el desarrollo de competencias genéricas y específicas que capacite a los y las participantes para transmitir la importancia de la Agenda 2030 en la universidad y la comunidad, desarrollando capacidades de reafirmación social para canalizar acciones encaminadas hacia los Objetivos de Desarrollo Sostenible (ODS). A través de la metodología del Aprendizaje-Servicio se busca promover un encuentro para el trabajo conjunto, mediante la conexión entre la individualidad de las personas, el trabajo grupal y comunitario. Los fundamentos del Trabajo Social nos permitirán trabajar un enfoque de derechos, valores y compromiso. Además, se promoverá el desarrollo de habilidades para la vida desde la educación popular, la educación eco-social, el diseño universal del aprendizaje, los entornos inclusivos, la lectura fácil y los huertos eco-didácticos. En el proyecto participará un grupo de veinte voluntarios/as (estudiantes de grado y máster de la Facultad de Trabajo Social y personas externas con diversidad intelectual), puntualmente estudiantes de Bellas Artes y Estudios Estadísticos. Como Aprendizaje, las actividades formativas programadas buscan formar al voluntariado tanto en los ODS como en las capacidades comentadas anteriormente. Para su desarrollo, se contará con recursos de las entidades colaboradoras, tanto propias de la UCM como externas. Como Servicio a la Comunidad, se propondrá al voluntariado el reto de ser embajadores/as de los ODS, compartiendo su mensaje en la universidad y comunidad, desde el conocimiento científico y el reconocimiento a los demás (cultura, saberes y procesos distintos a los nuestros). La gestión operativa se realizará a tres niveles: equipo técnico, para el seguimiento y evaluación del proyecto; equipo de acompañamiento, para coordinar actividades con el voluntariado y garantizar cohesión grupal; y equipo de relaciones institucionales, para coordinar con entidades colaboradoras los espacios y agenda para las actividades con el voluntariado.The main objective is to consolidate the development of generic and specific skills that train the participants to convey the importance of the 2030 Agenda in the university and the community, developing capacities for social reaffirmation to channel actions aimed at the Sustainable Development Goals ( ODS). Through the Service-Learning methodology, it seeks to promote a meeting for joint work, through the connection between the individuality of people, group and community work. The foundations of Social Work will allow us to work on a focus on rights, values ​​and commitment. In addition, the development of life skills will be promoted from popular education, eco-social education, universal learning design, inclusive environments, easy reading and eco-didactic gardens. A group of twenty volunteers will participate in the project (undergraduate and master's students from the Faculty of Social Work and external people with intellectual diversity), occasionally students of Fine Arts and Statistical Studies. As Learning, the programmed training activities seek to train volunteers both in the SDGs and in the capacities mentioned above. For its development, there will be resources from collaborating entities, both from the UCM and from outside. As Community Service, the challenge of being ambassadors of the SDGs will be proposed to volunteers, sharing their message in the university and community, based on scientific knowledge and recognition of others (culture, knowledge and processes different from ours). Operational management will be carried out at three levels: technical team, for the monitoring and evaluation of the project; support team, to coordinate activities with volunteers and guarantee group cohesion; and institutional relations team, to coordinate with collaborating entities the spaces and agenda for volunteer activities.Depto. de Trabajo Social y Servicios SocialesFac. de Trabajo SocialTRUEServicio ApS.
