Published: June 2023

Si le domaine de l’enseignement supérieur a fait l’objet de nombreux travaux analysant les inégalités sociales et de genre qui marquent les trajectoires étudiantes, il a encore peu été analysé sous l’angle des discriminations. Partant de ce constat, une équipe de recherche a lancé la recherche ACADISCRI, visant à mesurer et comprendre l’expérience des discriminations dans le monde académique. S’appuyant sur les données collectées lors de l’enquête « pilote » dans une université francilienne, l’article présente les premiers résultats de cette recherche. Il souligne la présence significative de traitements discriminatoires dans l’espace universitaire, particulièrement parmi les femmes et les minorités racialisées, de même que la faible connaissance et le rare recours aux dispositifs institutionnels permettant de les dénoncer.

Published: June 2023

Abstract
Thermal desorption spectroscopy using stable isotopes of 18O2 and D2 was employed to investigate the incorporation and behavior of oxygen-based species in a-IGZO films during plasma assisted processing. Specifically, the behavior of oxygen introduced during deposition with an Ar-18O2 plasma was assessed. The data show that the oxygen amount incorporated in these films during deposition was greatly reduced by a post-deposition plasma treatment. The OD radicals introduced into a-IGZO films deposited with Ar-16O2 during a post-treatment with an Ar + D2 + O2 mixture was also examined. The results indicate that −OD groups in the films were strongly bonded to the metal atoms.
Spatial distributions of the ion flux in a capacitive hydrogen RF discharge using a hollow cathode with double toroidal grooves enclosed by magnets
Authors: Ohtsu Yasunori , Hiwatashi Hokuto , Schulze Julian 
Published: June 2023

Abstract
A hydrogen high-density capacitively coupled plasma has been developed using a hollow cathode with double toroidal grooves enclosed by magnets and without an iron yoke disk. It is found that this plasma source allows generating higher plasma densities compared to the conventional RF magnetron plasma sources. Spatial distributions of the ion flux have been measured at various H2 gas pressures, p, of 1–20 Pa. It is found that the hybrid combination of a hollow cathode effect and magnetic confinement of electrons is attained for p ≥ 5 Pa, while for p ≤ 3 Pa, a conventional capacitive discharge is generated. The radial profile of the ion flux becomes uniform with increasing axial distance from the target for the hollow cathode discharge. The characteristic decay length of the roughness of the ion flux profile increases with increasing the gas pressure.

Abstract
In recent years, energy harvesting technology has become a promising power supply method for low-power wireless sensor nodes. According to the application requirements of energy acquisition, a piezoelectric and electrostatic hybrid vibration energy harvester (HVEH) is proposed in this paper. Compared with other vibration energy harvesters, the proposed hybrid harvester is easier to miniaturize and integrate into a MEMS. The electromechanical coupling model of the hybrid harvester is established. The optimal design of the proposed harvester is carried out based on numerical simulation. The optimal matching impedance of piezoelectric and electrostatic modules are calculated based on numerical simulation and validated through experiments, which are 80–90 kΩ and 15–20 MΩ, respectively. The output power of the HVEH is increased by 0.04%, 0.08%, 0.102%, and 0.097%, when the excitation acceleration is 0.1 g, 0.15 g, 0.2 g, and 0.25 g, respectively, compared with the single piezoelectric module.
Co-wide-bandgap conformally heteroepitaxial perovskite–monolithic SiC nanowire array with quantum-confined blue luminescence

Published: June 2023

Abstract
SiC is a wide-bandgap semiconductor with excellent mechanical and electrical properties and is a crucial template for epitaxially growing other semiconductors. We report the conformally epitaxial growth of the lead halide perovskites on the red-luminescent monolithic 6H-SiC nanowire arrays. The small lattice mismatch (0.8%) between SiC and CsPbBr3 ensures perfect heteroepitaxial growth of the CsPbBr3 quantum dots and nanosheets over the SiC nanowire arrays. The heteroepitaxial perovskites show intense multiband blue luminescence stemming from the strongly quantum-confined excitons with a twice prolonged lifetime compared with free nanocrystals. These blue-luminescent heteroepitaxial semiconductor–semiconductor nanostructures are promising nanophotonic device units.
Single time pixel imaging enabled by repurposing optoelectronic devices
Authors: Keyaki Ryota , Fukatsu Susumu 
Published: June 2023

Abstract
One-time readout temporal ghost imaging is attempted by utilizing optoelectronic devices that are not originally intended for signal photon detection purposes and as such slow by design. A visible light-emitting diode having a response time τ = 0.036 ms and a solar cell with τ = 3.1 ms are used to retrieve a rectangular pulse train, which is otherwise rounded with significant overlapping, in the image of a temporal mask simply by capturing data once at a selected single time pixel followed by division. Appropriate quality metrics and effective operation duration are discussed.

PRIMARY CULTURE AND IDENTIFICATION OF MOUSE BRAIN MICROVASCULAR ENDOTHELIAL CELLS
Authors: Mingcheng Liu 
Published: June 2023

Brain microvascular endothelial cells are the basic components of the blood-brain barrier. Many neurological diseases are related to the loss of blood brain barrier (BBB) function. Isolating and culturing primary BMVEC is an important means to study the function and regulation of BBB in vitro. To establish a method for isolation and culture of primary mouse brain microvascular endothelial cells (BMECs). The 7-10-days mice were sacrificed by neck removal, the cranial cavity was opened, the brain was aseptically removed and the cerebral cortex was retained. To extract brain microvascular segments, the brain underwent three D-Hank solution rinses. It was then homogenized, twice digested by enzyme, and centrifuged using a Bovine Serum Albumin (BSA) gradient. For primary culture, the brain microvascular segments were injected into gelatin-coated culture plates using DMED complete media. When the cell density reaches 90 %, the media is removed, and the cells are then given two PBS washes. A new medium was introduced after adding 1ml of the trypsin-EDTA solution to digest for 2–5 minutes for passage. Cell culture plates were rinsed and pre-cooled 95 % ethanol was added for 20 minutes after passaged cells had grown to 80–90 % of their original size. After a third wash, 1 ml of mouse factor VIII antibody was added to the culture wells, where it was left for 4 hours at 37 °C. FITC-labeled rabbit anti-mouse antibody in a volume of 1 mL was added. Under a confocal laser microscope, the plates were examined and taken pictures of. The outcome demonstrates positive expression of the marker factor VIII associated antigen. To create a cell suspension, monolayer-growing microvascular endothelial cells were chosen. 100 L of cell suspension was used to inoculate each well in 96-well plates, and the cells were then grown. On days 1, 2, 3, 4, 5, 6, and 7, the original medium was removed, and then 180 μL of DMEM and 20 μL of MTT were simultaneously added to each well for a 4-hour culture. After adding dimethyl sulfoxide (DMSO), each well's absorbance value (A value) was measured at 492 nm. The outcome demonstrates that the growth peak is attained between 6 and 8 days. This method can successfully isolate and culture primary BMECs, which lay a foundation for the study of BMEC in vitro.

A Census of the TW Hya Association with Gaia*
Authors: Luhman K. L. 
Published: June 2023

Abstract
I have used high-precision photometry and astrometry from the third data release of Gaia to perform a survey for members of the TW Hya association (TWA). I have identified candidate members that appear to share similar kinematics and ages with bona fide members compiled by Gagné et al. (2017), and I have assessed their membership using radial velocities and spectroscopic diagnostics of age from various sources. My new catalog of adopted members contains 67 Gaia sources in 55 systems. The histogram of spectral types for TWA peaks near M5 (∼0.15 M
⊙), resembling the distributions measured for other nearby young associations. The UVW velocities of its members indicate that the association is expanding. The rate of expansion corresponds to an age of

Myr when compared to the sequence for Upper Centaurus Lupus/Lower Centaurus Crux, for which an age of 20 Myr is assumed. Based on these expansion and isochronal ages, I have adopted an age of 10 ± 2 Myr for TWA. Finally, I have used mid-infrared photometry from the Wide-field Infrared Survey Explorer to check for excess emission from circumstellar disks among the TWA members. Fourteen members have detected disks, all of which have been reported in previous studies. The fraction of members at ≤ M6 (≳0.1 M

Spectroscopic Follow-up of Gaia Exoplanet Candidates: Impostor Binary Stars Invade the Gaia DR3 Astrometric Exoplanet Candidates
Authors: Marcussen Marcus L. , Albrecht Simon H. 
Published: June 2023

Abstract
In this paper, we report on the follow-up of six potential exoplanets detected with Gaia astrometry and provide an overview of what is currently known about the nature of the entire Gaia astrometric exoplanet candidate sample, 72 systems in total. We discuss the primary false-positive scenario for astrometric planet detections: binary systems with alike components that produce small photocenter motions, mimicking exoplanets. These false positives can be identified as double-lined binaries (SB2) through analysis of high-resolution spectra. Doing so we find that three systems, Gaia DR3 1916454200349735680, Gaia DR3 2052469973468984192, and Gaia DR3 5122670101678217728, are indeed near-equal-mass double-star systems rather than exoplanetary systems. The spectra of the other two analyzed systems, HD 40503 and HIP 66074, are consistent with the exoplanet scenario in that no second set of lines can be found in the time series of publicly available high-resolution spectra. However, their Gaia astrometric solutions imply radial-velocity semiamplitudes ∼3 (HD 40503) and ∼15 (HIP 66074) larger than what was observed with ground-based spectrographs. The Gaia astrometry orbital solutions and ground-based radial-velocity measurements exhibit inconsistencies in six out of a total of 12 exoplanet candidate systems where such data are available, primarily due to substantial differences between observed ground-based radial-velocity semiamplitudes and those implied by the Gaia orbits. We investigated various hypotheses as to why this might be the case, and although we found no clear perpetrator, we note that a mismatch in orbital inclination offers the most straightforward explanation.

Abstract
We present a search for extragalactic fast blue optical transients (FBOTs) during Phase I of the Zwicky Transient Facility (ZTF). We identify 38 candidates with durations above half-maximum light 1 day < t
1/2 < 12 days, of which 28 have blue (g − r ≲ −0.2 mag) colors at peak light. Of the 38 transients (28 FBOTs), 19 (13) can be spectroscopically classified as core-collapse supernovae (SNe): 11 (8) H- or He-rich (Type II/IIb/Ib) SNe, 6 (4) interacting (Type IIn/Ibn) SNe, and 2 (1) H&He-poor (Type Ic/Ic-BL) SNe. Two FBOTs (published previously) had predominantly featureless spectra and luminous radio emission: AT2018lug (The Koala) and AT2020xnd (The Camel). Seven (five) did not have a definitive classification: AT 2020bdh showed tentative broad Hα in emission, and AT 2020bot showed unidentified broad features and was 10 kpc offset from the center of an early-type galaxy. Ten (eight) have no spectroscopic observations or redshift measurements. We present multiwavelength (radio, millimeter, and/or X-ray) observations for five FBOTs (three Type Ibn, one Type IIn/Ibn, one Type IIb). Additionally, we search radio-survey (VLA and ASKAP) data to set limits on the presence of radio emission for 24 of the transients. All X-ray and radio observations resulted in nondetections; we rule out AT2018cow-like X-ray and radio behavior for five FBOTs and more luminous emission (such as that seen in the Camel) for four additional FBOTs. We conclude that exotic transients similar to AT2018cow, the Koala, and the Camel represent a rare subset of FBOTs and use ZTF’s SN classification experiments to measure the rate to be at most 0.1% of the local core-collapse SN rate.
The Roles of Dust Growth in the Temperature Evolution and Snow Line Migration in Magnetically Accreting Protoplanetary Disks
Authors: Kondo Katsushi , Okuzumi Satoshi , Mori Shoji 
Published: June 2023

Abstract
The temperature structure of protoplanetary disks provides an important constraint on where in the disks rocky planets like our own form. Recent nonideal magnetohydrodynamical (MHD) simulations have shown that the internal Joule heating associated with magnetically driven disk accretion is inefficient at heating the disk midplane. A disk temperature model based on the MHD simulations predicts that in a disk around a solar-mass young star, the water snow line can move inside the current Earth’s orbit within 1 Myr after disk formation. However, the efficiency of the internal Joule heating depends on the disk’s ionization and opacity structures, both of which are governed by dust grains. In this study, we investigate these effects by combining the previous temperature model for magnetically accreting disks with a parameterized model for the grain size and vertical distribution. Grain growth enhances the gas ionization fraction and thereby allows Joule heating to occur closer to the midplane. However, growth beyond 10 μm causes a decrease in the disk opacity, leading to a lower midplane temperature. The combination of these two effects results in the midplane temperature being maximized when the grain size is in the range 10–100 μm. Grain growth to millimeter sizes can also delay the snow line’s migration to the 1 au orbit by up to a few million years. We conclude that accounting for dust growth is essential for accurately modeling the snow line evolution and terrestrial planet formation in magnetically accreting protoplanetary disks.
A Tale of Three Dwarfs: No Extreme Cluster Formation in Extreme Star-forming Galaxies

Abstract
Nearly all current simulations predict that outcomes of the star formation process, such as the fraction of stars that form in bound clusters (Γ), depend on the intensity of star formation activity (ΣSFR) in the host galaxy. The exact shape and strength of the predicted correlations, however, vary from simulation to simulation. Observational results also remain unclear at this time, because most works have mixed estimates made from very young clusters for galaxies with higher ΣSFR with those from older clusters for galaxies with lower ΣSFR. The three blue compact dwarf (BCD) galaxies ESO 185-IG13, ESO 338-IG04, and Haro 11 have played a central role on the observational side because they have some of the highest known ΣSFR and published values of Γ. We present new estimates of Γ for these BCDs in three age intervals (1–10 Myr, 10–100 Myr, 100–400 Myr), based on age-dating, which includes Hα photometry to better discriminate between clusters younger and older than ≈10 Myr. We find significantly lower values for Γ(1–10 Myr) than published previously. The likely reason for the discrepancy is that previous estimates appear to be based on age–reddening results that underestimated ages and overestimated reddening for many clusters, artificially boosting Γ(1–10 Myr). We also find that fewer stars remain in clusters over time, with ≈15%–39% in 1–10 Myr clusters, ≈5%–7% in 10–100 Myr clusters, and ≈1%–2% in 100–400 Myr clusters. We find no evidence that Γ increases with ΣSFR. These results imply that cluster formation efficiency does not vary with star formation intensity in the host galaxy. If confirmed, our results will help guide future assumptions in galaxy-scale simulations of cluster formation and evolution.
