title: Evidence-based-practice profile among physiotherapists: a cross-sectional survey in France

description: To establish an inventory of the Evidence-Based Practice (EBP) among physiotherapists (PT) in France assessing EBP knowledge, perception, and utilisation in practice. A cross-sectional survey was performed using a French translation of the EBP<sup>2</sup> questionnaire including the 5 EBP domains (Relevance, Terminology, Confidence, Practice and Sympathy). Participants completed the online survey from February 26th to August 31st, 2021. Scores were summarised by EBP domain for each participant. Pairwise Pearson’s correlations between domains scores and a hierarchical clustering on principal component analysis were conducted. In total, 542 participants were included in the analysis. Majority of participants were male with median age of 30 years (IQR: 26–36 years). Regarding EBP domain scores, PT perceived relevance of EBP but had difficulty to apply it in practice. Furthermore, positive correlations exist between the 5 domains. Participants were divided into three clusters. Those reporting poor scientific analysis skills and high barriers were older, less graduated, less trained in EBP and graduated earlier. French PT perceived research to be important in their current practice and had a favourable opinion of EBP. However, they reported a lack of confidence, difficulty to understand terminology and to use it in practice. These findings and their profiles may help to improve PT’s EBP education in France.

title: Great urban shift - modelling settings for species distribution models of 2259 urban species in North America

description: The dataset comprises metadata for species distribution modeling outputs of 2259 distinct species. Each species has its own corresponding metadata file that contains essential information for the modeling process. The metadata files encompass a variety of details, including model parameters, MaxEnt settings, and species-specific information. The model parameters provide information into the variables and algorithms employed in the species distribution models. Additionally, the metadata files encompass species information, which can include taxonomic classification, the number of observations, and background points. The species modelled are urban species found in Canada and the United States. The modelling approach was used to assess changes in urban species as a result of climate change by the end of the century. Climate data was used from ClimateNA.

title: Energetic electron precipitation driven by electromagnetic ion cyclotron waves from ELFIN's low altitude perspective

description: We review comprehensive observations of electromagnetic ion cyclotron (EMIC) wave-driven energetic electron precipitation using data collected by the energetic electron detector on the Electron Losses and Fields InvestigatioN (ELFIN) mission, two polar-orbiting low-altitude spinning CubeSats, measuring 50-5000 keV electrons with good pitch-angle and energy resolution. EMIC wave-driven precipitation exhibits a distinct signature in energy-spectrograms of the precipitatingto- trapped ux ratio: peaks at &gt;0.5 MeV which are abrupt (bursty) (lasting 17s, or L 0:56) with signicant substructure (occasionally down to sub-second timescale). We attribute the bursty nature of the precipitation to the spatial extent and structuredness of the wave eld at the equator. Multiple ELFIN passes over the same MLT sector allow us to study the spatial and temporal evolution of the EMIC wave - electron interaction region. Case studies employing conjugate ground-based or equatorial observations of the EMIC waves reveal that the energy of moderate and strong precipitation at ELFIN approximately agrees with theoretical expectations for cyclotron resonant interactions in a cold plasma. Using multiple years of ELFIN data uniformly distributed in local time, we assemble a statistical database of 50 events of strong EMIC wave-driven precipitation. Most reside at L 5 􀀀 7 at dusk, while a smaller subset exists at L 8 􀀀 12 at postmidnight. The energies of the peak-precipitation ratio and of the half-peak precipitation ratio (our proxy for the minimum resonance energy) exhibit an L-shell dependence in good agreement with theoretical estimates based on prior statistical observations of EMIC wave power spectra. The precipitation ratio's spectral shape for the most intense events has an exponential fallo away from the peak (i.e., on either side of 1:45 MeV). It too agrees well with quasi-linear diusion theory based on prior statistics of wave spectra. It should be noted though that this diusive treatment likely includes effects from nonlinear resonant interactions (especially at high energies) and nonresonant effects from sharp wave packet edges (at low energies). Sub-MeV electron precipitation observed concurrently with strong EMIC wave-driven &gt;1MeV precipitation has a spectral shape that is consistent with effient pitch-angle scattering down to 200-300 keV by much less intense higher frequency EMIC waves at dusk (where such waves are most frequent). At 100 keV, whistler-mode chorus may be implicated in concurrent precipitation. These results conrm the critical role of EMIC waves in driving relativistic electron losses. Nonlinear effects may abound and require further investigation.

title: Remote Sensing of Sea Surface Glacial Meltwater on the Antarctic Peninsula Shelf

description: Glacial meltwater is an important environmental variable for ecosystem dynamics along the biologically productive Western Antarctic Peninsula (WAP) shelf. This region is experiencing rapid change, including increasing glacial meltwater discharge associated with the melting of land ice. To better understand the WAP environment and aid ecosystem forecasting, additional methods are needed for monitoring and quantifying glacial meltwater for this remote, sparsely sampled location. Prior studies showed that sea surface glacial meltwater (SSGM) has unique optical characteristics which may allow remote sensing detection via ocean color data. In this study, we develop a first-generation model for quantifying SSGM that can be applied to both spaceborne (MODIS-Aqua) and airborne (PRISM) ocean color platforms. In addition, the model was prepared and verified with one of the more comprehensive in-situ stable oxygen isotope datasets compiled for the WAP region. The SSGM model appears robust and provides accurate predictions of the fractional contribution of glacial meltwater to seawater when compared with in-situ data (r = 0.82, median absolute percent difference = 6.38%, median bias = −0.04), thus offering an additional novel method for quantifying and studying glacial meltwater in the WAP region.

title: Real-time Quantification of Size-Resolved Bioaerosols and Inert Particles in Spacecraft Assembly Facilities at the NASA Jet Propulsion Laboratory

description: Responsible space exploration is a cornerstone of planetary protection, particularly at sites in the solar system with a high potential for the existence of extant life. To limit bioburden, spacecraft assembly occurs in cleanrooms facilities. Cleanroom levels are established through air particulate counters; which can assess particle size distribution and concentration but cannot detect bioaerosols. Additionally, these devices do not detect in real-time, posing a risk to critical flight hardware assemblies or even mission timelines. A first-of-its-kind study was conducted to simultaneously detect bioaerosols, inert particles, and their size distribution in real-time, in operational spacecraft assembly cleanrooms at NASA’s Jet Propulsion Laboratory in Pasadena, CA, USA, using the BioVigilant IMD-A® 350 (Azbil Corporation, Tucson AZ, USA). The IMD-350A continuously sampled during operations and no-operation six-hour intervals in two facilities per cleanroom class: ISO-6, ISO-7, and ISO-8. A positive correlation was established between human presence in the cleanroom and elevated bioaerosol counts. Smaller particles of sizes 0.5 µm and 1 µm constituted an average ~91% of the total bioaerosols detected in "At Work" intervals across all ISO classes observed. The results of this study were used to establish bioburden particulate thresholds for the most stringent JPL cleanrooms used in the assembly of the Sample Caching System for the Mars 2020 Perseverance rover.

title: Type Ia Supernova cosmology combining data from the Euclid mission and the Vera C. Rubin Observatory

description: ABSTRACT The Euclid mission will provide first-of-its-kind coverage in the near infrared over deep (three fields, ∼10–20 square degrees each) and wide (∼10000 sq. deg) fields. While the survey is not designed to discover transients, the deep fields will have repeated observations over a two-week span, followed by a gap of roughly six months. In this analysis, we explore how useful the deep field observations will be for measuring properties of Type Ia supernovae. Using simulations that include Euclid’s planned depth, area and cadence in the deep fields, we calculate that more than 3700 SNe between 0.0 &lt; 𝑧 &lt; 1.5 will have at least five Euclid detections around peak with signal-to-noise ratio larger than 3. While on their own, Euclid light curves are not good enough to directly constrain distances, when combined with LSST deep field observations, we find that uncertainties on SN distances are reduced by 20-30 per cent for 𝑧 &lt; 0.8 and by 40-50 per cent for 𝑧 &gt; 0.8. Furthermore, we predict how well additional Euclid mock data can be used to constrain a key systematic in SN Ia studies — the size of the luminosity ‘step’ found between SNe hosted high mass (&gt; 1010𝑀⊙) and low mass (&gt; 1010𝑀⊙) galaxies. This measurement has unique information in the rest-frame NIR. If the step is caused by dust, we are expected to measure its reduction in the NIR compared to optical at the 4𝜎 level. We highlight that the LSST and Euclid observing strategies used in this work are still provisional and different scenarios need to be considered. However, our preliminary results are very promising. Moreover, assuming Euclid begins observations well before the Nancy Roman Space Telescope (Roman), this dataset can be extremely helpful for preparation for Roman itself.

title: Discovery of a Low-Redshift Hot Dust-Obscured Galaxy

description: We report the discovery of the hyperluminous, highly obscured AGN WISE J190445.04+485308.9 (W1904+4853 hereafter, Lbol ∼ 1.1 × 1013 L⊙) at z = 0.415. Its well-sampled spectral energy distri- bution (SED) is dominated by infrared dust emission, though broad emission lines are detected in the optical spectra. These features suggest that W1904+4853 contains an actively accreting supermassive black hole hidden in its dusty cocoon, resembling the observed properties of Hot Dust-Obscured Galaxies (Hot DOGs), a population previously only identified at z &gt; 1.0. Using the broad component of the Mg ii-2798 ̊A emission line, we estimate a black hole mass of log(MBH/M⊙) = 8.4 ± 0.3. The corresponding Eddington ratio (η) of 1.4 ± 0.2 implies that the central black hole accretion is at the theoretical limit of isotropic accretion. The rest-frame UV-optical SED and [Oii] emission line also indicate that the host galaxy of W1904+4853 harbors strong star formation activity at the rate of up to ∼ 55 M⊙ yr−1. With an estimated stellar mass of 3 × 1010 M⊙, the host galaxy appears to be a starburst system with respect to the main sequence of the star-forming galaxies at the same redshift. Although blueshifted and asymmetric [O III] emission provides evidence of an outflow, we estimate it to be an order of magnitude smaller than the star formation rate, indicating that the current obscured AGN activity at the center has not yet produced significant feedback on the host galaxy star formation activity. W1904+4853 supports the interpretation that Hot DOGs are a rare transitional phase of AGN accretion in galaxy evolution, a phase that can persist into the present-day Universe.

title: Electric Propulsion for the Psyche Mission: System-Level Integration and Test

description: NASA’s Psyche mission is planned to launch in 2022 and begin a 3.6-year cruise to the metallic asteroid Psyche, where it will examine this unique body. All primary propulsion will be done with the SPT-140-based electric propulsion subsystem. The Psyche mission will feature the first use of Hall thrusters for a NASA mission, and the first use of Hall thrusters beyond cis-lunar space. The spacecraft additionally uses a cold gas propulsion system with nitrogen propellant for maneuvers such as spacecraft safe mode control. The spacecraft has completed system-level integration and test activities for both propulsion subsystems at JPL and shipped to Kennedy Space Center for final launch preparations. An overview of the subsystem-level and system-level activities is described here, including feed system testing, mechanism deployments, integrated system testing with flight software, spacecraft environmental testing, and mission scenario testing. Some of the issues and problems encountered during this phase of the project are described, and finally the launch base test operations including propellant loading are discussed.

title: The Visible Mid-wave Dyson Imaging Spectrometer (VMDIS)

description: The Visible Mid-wave Dyson Imaging Spectrometer (VMDIS) is a JPL-developed prototype instrument whose main goal is to address three key technical challenges for the next generation of imaging spectrometers for solar system exploration: (1) High signal-to-noise ratio (SNR) measurements for mapping of minerals and volatiles on solar system targets including comets, asteroids, rocky moons, icy moons, and planets especially Mars; (2) Miniaturization for low-cost mission platforms (reducing the size, mass, and power requirements compared to current options); and (3) excellent spectral cross-track and spectral-spatial uniformity required by todays advanced algorithms for rigorous quantitation with uncertainties. The core of VMDIS is the imaging spectrometer instrument: an optically fast F/1.8 Dyson imaging spectrometer covering a spectral range from 600 nm to 3600 nm, with a spectral sampling of 7 nm. Different telescopes can be used with different implementations of VMDIS to tailor the IFOV and FOV of the instrument. With its prototype telescope, the instrument enables a field of view (FOV) of 28°, with an instantaneous FOV of 0.5 milliradians subtended by each 18 μm cross-track pixel. The size of the VMDIS prototype including the telescope and heritage electronics is roughly equal to 3U (3 units – 1 unit measuring approximately 10×10×10 cm), with a mass &lt; 8 kg and payload power &lt; 40 W. With next generation electronics in development this mass falls below 3 kg. We present an overview of the optical, mechanical, and thermal design of VMDIS, which is required to fabricate this instrument within very demanding resource allocations. The design of the signal chain electronics is also detailed. In addition, preliminary alignment, characterization, and calibration measurements, obtained with the instrument operating in relevant space-type environment, are also discussed. While tested with an available 30-μm detector array, VMDIS is designed for a 18-μm digital readout detector array. VMDIS is intended to pave the way for future low-cost, small form factor imaging spectrometers with state-of-the-art performance in terms of combination of spectral range, high throughput, exceptional uniformity, as well as configuration flexibility for both orbital and landed mission, for the next decade and beyond.

title: The Polstar High Resolution Spectropolarimetry MIDEX Mission

description: Polstar combines, for the first time, the complementary benefits of spectroscopy and polarimetry to probe the complex interface between massive stars and the interstellar medium. Furthermore, it leverages an innovative combination of effective area and time coverage, to reach the diversity of targets necessary to transform our understanding of the ecology of star and planet creation. Detailed knowledge of these bright, yet distant objects, is crucial for understanding the transformation of our galaxy, from the barren landscape of the early Big Bang, into the chemically enriched environment that produced the solar system we call home. Polstar will map stellar wind and magnetospheric structures by uniting time domain, polarimetry and spectroscopy capability in the near- and far-UV (NUV and FUV), which are densely populated with high-opacity resonance lines encoding a rich array of diagnostic information. UV spectropolarimetry is equally important for probing interstellar dust and protoplanetary disks. The instrument combines advances in high reflectivity UV coatings and delta-doped CCDs with high quantum efficiencies to provide dedicated FUV spectropolarimetry for the first time in 25 years. The FUV channel (Ch1), covers 122-200nm at resolution R=30k, while the NUV channel (Ch2) covers 122-320nm at R~140-4k. The instrumental polarization stability is built to provide signal-to-noise ratios (SNR) for UV polarimetry precision of 1x10-3 per exposure per resolution element (resel). Precision can be further improved with spectral binning and/or stacking multiple exposures. Polstar spectral resolution in Ch1 is &gt;30x better than WUPPE, with 10x better effective area, while reaching shorter wavelength than WUPPE to access strong lines of species like NIV and SiIV. The 3-year mission of Polstar is 100x longer than WUPPE with orders of magnitude gains in stellar and interstellar observations.

title: Multi-Frequency Imaging Results of 453 Extragalactic ICRF-3 Radio Sources from Multi Epoch, Near-Simultaneous Astrometric VLBA Observations

description: We present multi-frequency images of 452 compact extragalactic radio sources | most of them from the ICRF-3|with sub-milliarcsecond (sub-mas) resolution, based on Very Long Baseline Array (VLBA) imaging observations taken between April and June 2021. We compare images and astrometry from S (2.3 GHz), X (8.4 GHz), K (24 GHz) and Q-band (43 GHz) in order to study the astrophysical di erences and determine the optimal frequency band for Celestial Reference Frame observations. In order to do this we conducted multi-epoch, quasi-simultaneous S/X, K and Q- band astrometric-imaging observations. We characterise each source by the following properties: peak brightness, core and total ux density, the ratio of peak and core to total ux (compactness measure), radial source extent, structure index, source size, and jet direction. We will show how source structure compares amongst all four bands and we will assess the potential advantages of higher radio frequencies for Celestial Reference Frame work.
