Published: July 2024

As a promising sensing material, Molybdenum disulfide (MoS2) nanosheets is being increasingly studied for Nitrogen dioxide (NO2) gas sensing. However, the MoS2 nanosheets is prone to the stacking effect that compromises the sensing performances. Here, the stacking effect is mitigated by engineering MoS2 nanosheets into a three dimensional (3D) network microstructure, which was fabricated by method of electrostatically self-assembling of MoS2/SiO2 microspheres. The fabricated sensor based on 3D MoS2 network observed a significantly improved response of 15% to 12.3 ppm NO2, which is a 75-fold increase compared to the control sensor with pure MoS2 nanosheets. In addition, the sensitivity of the sensor with 3D MoS2 network was 6.15 times larger than that of the control sensor with pure MoS2 nanosheets. The detection limit of our sensor was 0.297 ppm, lower than most of reported MoS2-based NO2 sensors. The enhanced sensitivity and dynamic response stem from the improved interaction between NO2 molecules and MoS2 network, thanks to its increased surface area per footprint of MoS2 nanosheets compared to pure 2D MoS2 film (single- or few-layer). This work presents a new approach to enhancing the performance of gas sensors based on 2D materials.

Published: July 2024

IntroductionProlonged and repeated exercise performed during an ultra-endurance event can induce general and cardiac fatigue known as exercise-induced cardiac fatigue. Our objective was to find a possible correlation between the cardiac function and the autonomic cardiac function.MethodsDuring a multistage ultra-endurance event, a female well-trained cyclist underwent daily rest echocardiography and heart rate variability measurements to assess the cardiac function and the cardiac autonomic function.ResultsThe athlete completed 3,345 km at 65% of her maximum heart rate and 39% of her maximum aerobic power. A progressive improvement of the systolic function for both the left ventricle and the right ventricle was observed during the event.DiscussionAlterations were observed on the cardiac autonomic function with an imbalance between sympathetic and parasympathetic, but there was no sign of a significant correlation between the cardiac function and the autonomic cardiac function and no signs of cardiac fatigue either. Further analysis should be performed on a larger sample to confirm the obtained results.

Published: July 2024

IntroductionClaw lesions significantly contribute to lameness, greatly affecting sow welfare. This study investigated different factors that would impact the severity of claw lesions in the sows of Brazilian commercial herds.MethodsA total of 129 herds (n= 12,364 sows) were included in the study. Herds were in the Midwest, Southeast, or South regions of Brazil. Inventory sizes were stratified into 250–810 sows, 811–1,300 sows, 1,301–3,000 sows, and 3,001–10,000 sows. Herds belonged to Cooperative (Coop), Integrator, or Independent structures. The herd management was conducted either maintaining breeds from stock on-site (internal), or through purchase of commercially available genetics (external). Herds adopted either individual crates or group housing during gestation. Within each farm, one randomly selected group of sows was scored by the same evaluator (two independent experts evaluated a total of 129 herds) from 0 (none) to 3 (severe) for heel overgrowth and erosion (HOE), heel-sole crack (HSC), separation along the white line (WL), horizontal (CHW) and vertical (CVW) wall cracks, and overgrown toes (T), or dewclaws (DC) in the hind legs after parturition. The study assessed differences and similarities between herds using Principal Component Analysis (PCA) and Hierarchical Agglomerative Clustering (HAC) analysis. The effects of factors (i.e., production structure, management, housing during gestation, and region) were assessed using the partial least squares method (PLS).Results and discussionHeel overgrowth and erosion had the highest prevalence, followed by WL and CHW, while the lowest scores were observed for T, DC, and CVW. Herds were grouped in three clusters (i.e., C1, C2, and C3). Heel overgrowth and erosion, HSC, WL, CHW, CVW, and T were decreased by 17, 25, 11, 25, 21, and 17%, respectively, in C3 compared to C1 and 2 combined. Independent structure increased the L-Index in all three clusters. Furthermore, individual housing increased the L-Index regardless of the cluster. The results suggest that shifting toward larger, more technologically advanced herds could potentially benefit claw health. Additionally, adopting group gestation housing appears to mitigate the adverse effects on claw health, although further validation is necessary, as Brazil has only recently transitioned from individual housing practices.
How, when, and who should ask about pregnancy intentions in primary care? A qualitative study of primary healthcare professionals’ preferences
Authors: Hall Jennifer , Carr Helen , Connolly Anne , Barrett Geraldine 
Published: July 2024

Background
Knowing people’s pregnancy intentions would help healthcare professionals (HCPs) to take a more holistic approach to reproductive health and preconception care.

Aim
To assess the feasibility of implementation of questions about pregnancy preferences in a range of primary care settings in Great Britain, including digital implementation.

Design & setting
Qualitative study using online semi-structured interviews with primary healthcare professionals across Great Britain between February and July 2022.

Method

Twelve online interviews were conducted with GPs (
n
= 3), practice nurses (
n
= 3), sexual and reproductive health professionals (
n
= 4), and health visitors (
n
= 2). Framework analysis was conducted in NVivo, adapting a coding frame from complementary interviews with women.

Results
HCPs perceived asking about pregnancy preferences as valuable in meeting patients’ reproductive health needs and most suited to women’s health consultations, medication and disease reviews, baby checks, or as an addition to lifestyle questions leading to health promotion advice. An introductory, non-discriminatory signposting sentence was well-liked, and the preferred question in a face-to-face clinical encounter was asking how the person would feel about a pregnancy in the next year, in line with women’s preference. Guidance and training would give clinicians confidence in knowing how to ask about pregnancy preferences and advise their patients accordingly.

Conclusion
Asking about pregnancy intentions is acceptable to women and HCPs and feasible in primary care, but implementation needs to be adapted to the patient and context. Digital options that enable patients to self-manage can reduce the need for HCP input and avoid medicalising a normal process.

Published: July 2024

Abstract
Chemical doping of carbon nanotubes (CNTs) by adsorption with high-temperature-tolerant molecules is required for the fabrication of various types of electronic devices for their performance maintenance under harsh thermal conditions during the fabrication and operation processes. Here, we demonstrate the fabrication of CNT thin film pn junction diodes using a combination of 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile as a p-dopant and a complex salt of potassium hydroxide and benzo-18-crown-6 ether as an n-dopant. The fabricated devices demonstrated a reasonably stable rectifying behavior, even after heating to 200 °C for 300 min.

Published: July 2024

We conducted a systematic literature review to find out how physics teachers’ PCK has been captured over the 10 years. Following identification and screening process using PRISMA flowchart method, we found 29 articles and conference proceedings are eligible. Three instruments often used by researchers to capture physics teachers' PCK are interview guidelines, CoRes and questionnaires. We explore the impact of physics teachers' PCK influences physics learning for students, we need to see teachers' enacted PCK in the classroom, observation sheet or learning video assessment sheet is required. Among factors that affect physics teachers' PCK is teacher development program. Things that should be considered in teacher's PCK development program are phases when teachers develop lesson plans (development phase) and phases when teachers perform the lessons (class enactment phase). The connection between capture physics teachers' PCK, correlation between physics teachers' PCK on students' learning, and physics teachers' PCK development program were discussed.
Establishing Baselines for Six Short-period δ Scuti Variables

Published: July 2024

Abstract
As part of our variable star follow-up program, we have examined a number of stars from the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey. Using a combination of our own data, ATLAS data, and other archival data, we confirmed the published periods and established a baseline ephemeris for each star. This initial sample of six stars are from the PUL or mono-periodic set from the ATLAS survey. Our determined periods agreed well with the published values. Five targets were found to be high amplitude δ Scuti variables (HADS), and one a low-amplitude δ Scuti (LADS). Beyond the primary period we examined the frequency content, Q value, position in the PL relation, and position within the instability strip of each object. We found ATO J070.9950+37.4038 to be the most complex target. The frequency content is likely a set of nonradial pulsations. ATO J328.8034+58.0406 is a multiperiodic HADS variable that is pulsating in the first and second overtones. ATO 345.4240+42.0479 was found to be a simple HADS monoperiodic fundamental pulsator. In the case of ATO J086.0780+30.3287, we found a strong fundamental pulsation with many harmonics and a weaker first overtone pulsation. We classify ATO J086.0780+30.3287 as a HADS. ATO J077.6090+36.5619 was found to be an interesting case of a monoperiodic star that appears to be pulsating in the third overtone. The lower amplitude for this target would put it in the LADS group. ATO J045.8159+46.0090 was found to be a multiperiodic HADS pulsating in the first and second overtones.
Simulating the Arrival of the Southern Substructure in the Galaxy Cluster Abell 1758

Published: July 2024

Abstract
Abell 1758 (z ∼ 0.278) is a galaxy cluster composed of two structures, A1758N and A1758S, separated by ∼2.2 Mpc. The northern cluster is itself a dissociative merging cluster that has already been modeled by dedicated simulations. Recent radio observations revealed the existence of a previously undetected bridge connecting A1758N and A1758S. New simulations are now needed to take into account the presence of A1758S. We wish to evaluate which orbital configuration would be compatible with a bridge between the clusters. Using N-body hydrodynamical simulations that build upon the previous model, we explore different scenarios that could have led to the current observed configuration. Five types of orbital approaches were tested: radial, tangential, vertical, postapocentric, and outgoing. We found that the incoming simulated scenarios are generally consistent with mild enhancements of gas density between the approaching clusters. The mock X-ray images exhibit a detectable bridge in all cases. Compared to measurements of Chandra data, the amplitude of the X-ray excess is overestimated by a factor of ∼2–3 in the best simulations. The scenario of tangential approach proved to be the one that best matches the properties of the profiles of X-ray surface brightness. The scenarios of radial approach of vertical approach are also marginally compatible.

Abstract
We study the impact of warm dark matter (WDM) mass on the internal properties of individual galaxies using a large suite of 1024 state-of-the-art cosmological hydrodynamic simulations from the DREAMS project. We take individual galaxies’ properties from the simulations, which have different cosmologies, astrophysics, and WDM masses, and train normalizing flows to learn the posterior of the parameters. We find that our models cannot infer the value of the WDM mass, even when the values of the cosmological and astrophysical parameters are given explicitly. This result holds for galaxies with stellar mass larger than 2 × 108

−1 at both low and high redshifts. We calculate the mutual information and find no significant dependence between the WDM mass and galaxy properties. On the other hand, our models can infer the value of Ωm with a ∼10% accuracy from the properties of individual galaxies while marginalizing astrophysics and WDM masses.
Institutionnalisation d’une expérimentation pour l’emploi au prisme de l’analyse processuelle
Authors: Retsin Camille , Petrella Francesca 
Published: July 2024

L’objectif de cet article est d’analyser le processus d’institutionnalisation de l’expérimentation « Territoires zéro chômeur de longue durée » sur Jouques (Sud Provence Alpes Côte d’Azur, France). Nous considérons l’expérimentation comme une innovation sociale dans le champ des politiques publiques de l’emploi. L’institutionnalisation des innovations sociales se comprend comme la formalisation progressive des pratiques sociales afin de pérenniser l’action menée par les acteurs sur un territoire. En mobilisant les données empiriques collectées dans le cadre d’un travail de thèse centré sur l’expérimentation, nous proposons d’utiliser l’analyse processuelle afin de présenter nos résultats. Cette dernière nous permet de faire émerger les séquences à partir de l’identification des ingrédients, des moteurs et des bifurcations ayant eu lieu sur le territoire.
Se marier « hors saison » ?
Authors: Meslay Gaëlle 
Published: July 2024

Au cours du xx e siècle, le rituel matrimonial a profondément évolué, affectant sa saisonnalité. Dans un contexte d’affaiblissement institutionnel, le mariage est devenu, pour celles et ceux qui le choisissent, un rituel de personnalisation du couple, reposant sur de forts enjeux esthétiques. Mais depuis que les couples de même sexe ont obtenu la possibilité de se marier, en 2013, leurs choix suivent-ils la saisonnalité des mariages de couples de sexe différent ? Cet article explore l’atypisme dans leurs dates de mariage, montrant que celui-ci est en partie explicable par la place qu’occupent les usages juridiques du mariage pour ces couples. Il souligne également d’importantes différences genrées sur ce point, l’atypisme des couples de femmes renvoyant davantage à des choix saisonniers, tandis que celui des hommes concerne plus spécifiquement le jour de la semaine. Cela peut s’expliquer par les motivations juridiques des femmes, davantage centrées sur l’accès à l’adoption et à l’établissement de la filiation, donnant lieu à une répartition des cérémonies au fil de l’année en fonction de l’aboutissement de leurs projets parentaux.
La recherche-action collaborative dans le milieu de la petite enfance : une multiplicité de médiums entre science, design et terrain
Authors: Voillot Marion , Vettier Lou , Jacquey Lisa 
Published: July 2024

Entre soin et éducation, le milieu de la petite enfance (0-6 ans) est un domaine complexe au sein duquel cohabitent les tout-petits et leurs donneur·ses de soin (caregivers) dans différents environnements allant du foyer familial aux lieux d’éveil et d’éducation. Face aux nombreuses problématiques auxquelles le milieu de la petite enfance doit faire face ces dernières années, l’enjeu de (re)donner le pouvoir d’agir aux professionnel·les de terrain est essentiel. Pour cela, il est nécessaire de créer des ponts entre la recherche scientifique et les problématiques de terrain. Pour parvenir à cet objectif, l’association Premiers Cris facilite la réalisation de projets de recherche-action collaborative (RAC) associant professionnel·les de terrain, scientifiques et designers, dans une démarche d’horizontalité des savoirs et de reconnaissance des pratiques de chaque co-chercheur·e. Ainsi, différents médiums sont mobilisés tout au long d’un projet de RAC : la méthodologie, le dispositif et la médiation, répondant chacun à des objectifs complémentaires. Afin d’illustrer notre propos, nous présenterons la réalisation d’un projet de RAC mené au sein de plusieurs écoles maternelles entre septembre 2022 et juin 2023 en espérant que cette démarche pourra inspirer d’autres milieux que celui de la petite enfance pour faire de la recherche « autrement ».

Published: July 2024

Cet article présente une recherche interdisciplinaire par le design sur l’expérience de la dialyse à domicile et la communication entre patients, aidants et soignants (PAS). Nous précisons d’abord le besoin de recherche sur cette pathologie et la nécessité d’une approche spécifique pour prendre en compte l’expérience-patient et la rendre compréhensible et partageable. À partir d’une méthodologie ancrée dans le codesign, nous présentons le dispositif d’enquête, cocréé avec les patients en contexte de pandémie de COVID-19 de 2021 à 2023, basé sur la communication épistolaire et la photographie. Nous analysons le processus de cocréation des objets de médiation et son rôle dans la transformation des relations entre les patients et le chercheur. Les résultats présentés portent sur la factitivité des médias du codesign, en valorisant leur matérialité pour engager les participants dans l’enquête collective jusqu’aux ateliers de codesign. Nous montrons que la matérialité de ces objets de médiation a évolué en fonction de trois formes de médiation dans le projet participatif : s’immerger, coconcevoir et communiquer.
