Simpósio Transexualidade no Brasil: Dilemas e Perspectivas, um relato de experiência

Introduction: The precariousness of public policies on access to health and the purely biomedical notion that permeates health related courses compromise the guarantee of integral health to the trans population in the Brazilian scenario. With this in mind, the objective of this report is to expose the steps for the realization of the symposium on the health of the trans population, done through a remote platform, as well as to explain what were the difficulties and advantages in doing it. Experience Report: The activity “Simpósio Transexualidade no Brasil: Dilemas e Perspectivas” was idealized in an Activity Planning Meeting, with subsequent selection of  8 affiliates interested in coordinating it. The Symposium registrations were made through the Even3 platform, using Instagram and WhatsApp by means of promotion. The event was held between April 7th and 15th, 2021, with transmissions made through YouTube. Both lectures and round tables were conducted, mostly, by trans people and had 355 listeners, including professionals and students from health and other areas. Discussion: The impact assessment revealed the great learning and that there is little knowledge and understanding of the participants regarding the needs of the trans population, being evident the capacity of the event to elucidate particularities of the health care of this population. Moreover, it showed the negligence that many universities have to approach in a humanized way this theme so essential for the training of a health professional and enlightened the importance of the existence of public policies to support this public. Conclusion: The Symposium fulfilled its objective of joining health education initiatives regarding humanized care aimed towards the trans population, however, other similar initiatives should be developed in order to promote discussions on the topic.Introdução: A precarização de políticas públicas de acesso à saúde e a noção puramente biomédica que permeia os cursos da área  da saúde comprometem a garantia de saúde integral à população trans no cenário brasileiro. Tendo isso em vista, o objetivo deste relato é discorrer sobre as etapas para a realização do simpósio sobre a saúde da população trans, realizado de forma remota,  bem como expor as dificuldades e vantagens ao realizá-lo. Relato de Experiência: A atividade “Simpósio Transexualidade no Brasil: Dilemas e Perspectivas” foi idealizada em uma Reunião de Planejamento de Atividades, com subsequente seleção dos 8 filiados interessados em coordená-la. As inscrições do Simpósio foram realizadas a partir da plataforma Even3, utilizando-se do Instagram e WhatsApp como meios de divulgação. O evento foi realizado entre 07 e 15 de abril de 2021, com transmissões realizadas através do Youtube. Tanto as palestras quanto as mesas redondas foram conduzidas, em sua maioria, por pessoas trans e contaram com 355 ouvintes, entre profissionais e estudantes de saúde e de outras áreas. Discussão: A avaliação de impacto revelou o grande aprendizado e que havia pouco conhecimento e compreensão dos inscritos sobre as necessidades da população trans, sendo evidente a capacidade do evento em elucidar particularidades do atendimento em saúde a essa  população. Além disso, evidenciou a negligência que muitas universidades têm de abordar de forma humanizada essa temática tão essencial para a formação de um profissional de saúde e ressaltou a importância da existência de políticas públicas de amparo para esse público. Conclusão: O Simpósio cumpriu seu objetivo de somar-se às iniciativas de educação em saúde a respeito do cuidado humanizado voltado para a população trans. Logo, outras iniciativas similares devem ser desenvolvidas no intuito de promover discussões a respeito do tema

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

The LHCb upgrade I

International audienceThe LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger than that of the previous running periods. Readout of all detectors into an all-software trigger is central to the new design, facilitating the reconstruction of events at the maximum LHC interaction rate, and their selection in real time. The experiment's tracking system has been completely upgraded with a new pixel vertex detector, a silicon tracker upstream of the dipole magnet and three scintillating fibre tracking stations downstream of the magnet. The whole photon detection system of the RICH detectors has been renewed and the readout electronics of the calorimeter and muon systems have been fully overhauled. The first stage of the all-software trigger is implemented on a GPU farm. The output of the trigger provides a combination of totally reconstructed physics objects, such as tracks and vertices, ready for final analysis, and of entire events which need further offline reprocessing. This scheme required a complete revision of the computing model and rewriting of the experiment's software
