Recent mid-infrared observations with JWST's Mid-Infrared Instrument Low Resolution Spectrometer (MIRI LRS) have resulted in the first direct detections of absorption features from silicate clouds in the transmission spectra of two transiting exoplanets, WASP-17 b and WASP-107 b. In this Letter, we measure the mid-infrared (5–12 μm) dayside emission spectrum of the benchmark hot Jupiter HD 189733 b with MIRI LRS by combining data from two secondary-eclipse observations. We confirm the previous detection of H2O absorption at 6.5 μm from Spitzer's Infrared Spectrograph (IRS) and additionally detect H2S as well as an absorption feature at 8.7 μm in both secondary-eclipse observations. The excess absorption at 8.7 μm can be explained by the presence of small (∼0.01 μm) grains of SiO2[s] in the uppermost layers of HD 189733 b’s dayside atmosphere. This is the first direct detection of silicate clouds in HD 189733 b’s atmosphere, and the first detection of a distinct absorption feature from silicate clouds on the dayside of any hot Jupiter. We find that models including SiO2[s] are preferred by 6–7σ over clear models and those with other potential cloud species. The high-altitude location of these silicate particles is best explained by formation in the hottest regions of HD 189733 b’s dayside atmosphere near the substellar point. We additionally find that HD 189733 b’s emission spectrum longward of 9 μm displays residual features not well captured by our current atmospheric models. When combined with other JWST observations of HD 189733 b’s transmission and emission spectra at shorter wavelengths, these observations will provide us with the most detailed picture to date of the atmospheric composition and cloud properties of this benchmark hot Jupiter.
A Far-ultraviolet-detected Accretion Shock at the Star–Disk Boundary of FU Ori
Authors: Carvalho Adolfo S. , Hillenbrand Lynne A. , France Kevin , Herczeg Gregory J.
Published: September 2024

FU Ori objects are the most extreme eruptive young stars known. Their 4–5 mag photometric outbursts last for decades and are attributed to a factor of up to 10,000 increase in the stellar accretion rate. The nature of the accretion disk-to-star interface in FU Ori objects has remained a mystery for decades. To date, attempts to directly observe a shock or boundary layer have been thwarted by the apparent lack of emission in excess of the accretion disk photosphere down to λ = 2300 Å. We present a new near-ultraviolet and the first high-sensitivity far-ultraviolet (FUV) spectrum of FU Ori. The FUV continuum is detected for the first time and, at λ = 1400 Å, is more than 104 times brighter than predicted by a viscous accretion disk. We interpret the excess as arising from a shock at the boundary between the disk and the stellar surface. We model the shock emission as a blackbody and find that the temperature of the shocked material is T
FUV ≈ 16,000 ± 2000 K. The shock temperature corresponds to an accretion flow along the surface of the disk that reaches a velocity of 40 km s−1 at the boundary, consistent with predictions from simulations.
Quantum Statistical Effects on Warm Dark Matter and the Mass Constraint from the Cosmic Structure at Small Scales
Authors: Zhang Zhijian , Lin Weikang
Published: September 2024

The suppression of the small-scale matter power spectrum is a distinct feature of warm dark matter (WDM), which permits a constraint on the WDM mass from galaxy surveys. In the thermal relic WDM scenario, quantum statistical effects are not manifest. In a unified framework, we investigate the quantum statistical effects for a fermion case with degenerate pressure and a boson case with Bose–Einstein condensation (BEC). Compared to the thermal relic case, the degenerate fermion case only slightly lowers the mass bound, while the boson case with a high initial BEC fraction (≳90%) significantly lowers it. On the other hand, the BEC fraction drops during the relativistic-to-nonrelativistic transition and completely disappears if the initial fraction is below ∼64%. Given the rising interest in resolving the late-time galaxy-scale problems with boson condensation, a question is posed on how a high initial BEC fraction can be dynamically created so that a dark matter condensed component remains today.

The way pulsars spin down is not understood in detail, but a number of possible physical mechanisms produce a spin-down rate that scales as a power of the rotation rate (

ν

̇

∝
−

ν

n

), with the power-law index n called the braking index. PSR B0540−69 is a pulsar that in 2011, after 16 yr of spinning down with a constant braking index of 2.1, experienced a giant spin-down change and a reduction of its braking index to nearly zero. Here, we show that, following this episode, the braking index monotonically increased during a period of at least 4 yr and stabilized at ∼1.1. We also present an alternative interpretation of a more modest rotational irregularity that occurred in 2023, which was modeled as an anomalous negative step of the rotation rate. Our analysis shows that the 2023 observations can be equally well described as a transient swing of the spin-down rate (lasting ∼65 days), and the Bayesian evidence indicates that this model is strongly preferred.
Nonlinear Alfvén-wave Dynamics and Premerger Emission from Crustal Oscillations in Neutron Star Mergers
Authors: Most Elias R. , Kim Yoonsoo , Chatziioannou Katerina , Legred Isaac
Published: September 2024

Neutron stars have solid crusts threaded by strong magnetic fields. Perturbations in the crust can excite nonradial oscillations, which can in turn launch Alfvén waves into the magnetosphere. In the case of a compact binary close to merger involving at least one neutron star, this can happen through tidal interactions causing resonant excitations that shatter the neutron star crust. We present the first numerical study that elucidates the dynamics of Alfvén waves launched in a compact binary magnetosphere. We seed a magnetic field perturbation on the neutron star crust, which we then evolve in fully general-relativistic force-free electrodynamics using a GPU-based implementation. We show that Alfvén waves steepen nonlinearly before reaching the orbital light cylinder, form flares, and dissipate energy in a transient current sheet. Our results predict radio and X-ray precursor emission from this process.
Alpha–Proton Differential Flow of a Coronal Mass Ejection at 15 Solar Radii

Published: September 2024

Alpha–proton differential flow (V

α
p
) of coronal mass ejections (CMEs) and solar wind from the Sun to 1 au and beyond could influence the instantaneous correspondence of absolute abundances of alpha particles (He2+/H+) between the solar corona and interplanetary space as the abundance of a coronal source can vary with time. Previous studies based on Ulysses and Helios showed that V

α
p
is negligible within CMEs from 5 to 0.3 au, similar to slow solar wind (<400 km s−1). However, recent new observations using Parker Solar Probe (PSP) revealed that the V

α
p
of slow wind increases to ∼60 km s−1 inside 0.1 au. It is important to answer whether the V

α
p
of CMEs exhibits similar behavior near the Sun. In this Letter, we report the V

α
p
of a CME measured by PSP at ∼15 R
⊙ for the first time, which demonstrates that the V

α
p
of CMEs is obvious and complex inside 0.1 au while keeping lower than the local Alfvén speed. A very interesting point is that the same one CME duration can be divided into A and B intervals clearly with Coulomb number below and beyond 0.5, respectively. The means of V

α
p
and alpha-to-proton temperature ratios of interval A (B) is 96.52 (21.96) km s−1 and 7.65 (2.23), respectively. This directly illustrates that Coulomb collisions play an important role in reducing the nonequilibrium features of CMEs. Our study indicates that the absolute elemental abundances of CMEs also might vary during their propagation.
Albums photographiques et construction du barrage de Sukkur : un point de vue subalterne dans l’Inde sous domination coloniale (1920-1940)
Authors: Caru Vanessa
Published: September 2024

Le point de départ de cet article consiste en deux albums photographiques, conservés par la famille d’un ingénieur indien, qui documentent la mise en œuvre du chantier du grand barrage de Sukkur, situé dans l’État actuel du Pakistan, entre 1927 et 1931. La démarche adoptée explore les manières d’utiliser cette archive photographique pour objectiver, par-delà le caractère très technique que revêtent au premier abord les images, le point de vue d’un subalterne et pour servir de révélateur à l’imbrication des hiérarchies (raciales, de classe, etc.) internes à la société coloniale.

Utilisation du réseau Instagram pour le « Soin de soi » : Quelles implications pour les interventions de marketing social ?
Authors: Martin Annabel
Published: September 2024

Parmi les médias sociaux, Instagram est souvent positionné comme pouvant motiver des comportements de soin de soi tels qu’une activité physique régulière ou une consommation alimentaire saine et équilibrée. L’étude qualitative réalisée dans un premier temps identifie les apports perçus d’Instagram par les utilisatrices du média ainsi que leurs avis sur les contenus et les interactions sociales dans ce domaine. Elle se prolonge par le développement et le test d’un modèle dont les résultats confirment que la congruence des contenus avec le soi et l’authenticité perçue des interactions contribuent à la motivation de persévérance dans une activité de soin de soi, par l’intermédiaire et respectivement, d’une expansion de soi spécifique à l’activité et d’un sentiment de communauté. Les résultats confirment aussi que cette authenticité et ce sentiment motivent aux divulgations négatives de soi dans le but de recevoir ou d’apporter un soutien social aux efforts de changement comportemental. L’ensemble conduit aux préconisations pour les interventions de marketing social en termes de recrutement au compte d’intervention et de stratégie éditoriale et d’engagement média des personnes recrutées, ainsi que pour les communautés de pratique autour de hashtags et les groupes privés de changement comportemental, ou pour contrer des communications relatives au soin de soi mais risquées pour la santé.
Télétravail, inégalités de genre et rémunération : influence de la formalisation
Authors: Hachard Virginie , Diard Caroline , Laroutis Dimitri
Published: September 2024

Imposé en 2020, le télétravail s’installe durablement en mode hybride. Recommandé par le ministère du Travail puis obligatoire dès le 3 janvier 2022, il s’exerce alors à nouveau dans un cadre contraignant. L’obligation prend fin le 2 février 2022 . Le travail exercé à domicile a bouleversé l’organisation intra-familiale, contribué à un accroissement de la charge de travail et à des situations de stress ou d’isolement. Le télétravail à domicile s’est exercé dans des conditions inégales en fonction du lieu de vie et de la position sociale du ménage, ainsi que du sexe (Étude COCONEL, 2020 ; Boston Consulting Group, 2021). Notre démarche s’inscrit dans ce questionnement et vise à démontrer l’impact éventuel de la formalisation du travail à domicile sur les inégalités de genre et l’influence sur la rémunération. La partie empirique repose sur une étude quantitative menée en 2022 auprès de 211 répondants travaillant à domicile. Nous mobilisons la littérature sur le télétravail, les inégalités, la théorie des conventions et les théories contractualistes. Les résultats révèlent que la formalisation du travail à domicile n’influence pas la rémunération, les facteurs de contingence (formalisation induite) en revanche produisent des inégalités de genre en matière de rémunération. L’absence d’espace de travail dédié à domicile engendre des inégalités de rémunération .
La créativité de l’intelligence humaine augmentée par l’IA

Published: September 2024

L’article examine la créativité sous l’angle de l’intelligence artificielle (IA) et de son interaction avec la créativité humaine. Traditionnellement perçue comme une faculté exclusivement humaine, la créativité a été redéfinie avec l’avènement de l’IA, en particulier grâce aux progrès en apprentissage profond et en réseaux neuronaux. Ce développement a engendré un débat académique sur la capacité créative de l’IA, avec des opinions variées parmi les chercheurs . L’impact de l’IA sur la créativité organisationnelle est notable, particulièrement en termes d’innovation et d’avantages concurrentiels. Mais le cœur du débat repose sur la question de la créativité intrinsèque de l’IA et son interaction avec la créativité humaine. L’étude vise à comparer et comprendre la créativité humaine et celle de l’IA, ainsi qu’à analyser leur interaction pour obtenir une créativité combinée, dont nous examinons finalement les perspectives de développement .
L’internationale des chemises noires
Authors: Cuzzi Marco
Published: September 2024

Les Comités d’action pour l’universalité de Rome représentent l’application pratique d’un ensemble de théories élaborées dès le milieu des années 1930, relatives à l’« universalité du fascisme ». Le régime fasciste, définitivement consolidé, avait progressivement abandonné la thèse de la non exportabilité de son modèle à mesure qu’il observait l’éclosion dans toute l’Europe de partis et mouvements plus ou moins inspirés par la doctrine de Mussolini. C’est ainsi qu’il décide de fédérer ces groupements fascistes ou fascisants. L’histoire des CAUR doit cependant être lue à la lumière des relations franco-allemandes, puisque l’alignement sur l’Allemagne privait de plus en plus les CAUR de toute substance.

Cet article voudrait participer à une meilleure compréhension du rôle de passeur politique et culturel du fascisme italien à l’étranger, à travers l’analyse d’un cas d’étude précis : celui des conférenciers politiques italiens actifs dans l’Europe de l’entre-deux-guerres. Il s’agit alors, en se plaçant à hauteur d’acteurs et de transferts, d’interroger les ambitions personnelles et les stratégies de propagande mobilisées par certains intellectuels pour s’imposer en tant que conférenciers politiques aux yeux des élites étrangères, mais aussi de l’État fasciste.
« Per l’Italia nella sua Lotta »

Parmi les passeurs culturels et politiques du fascisme italien en Roumanie se détache la figure de l’historien Nicolae Iorga (1871-1940) dont la stature intellectuelle a apporté un surcroît de crédibilité à la diffusion d’une image positive de Mussolini et de son régime. Il est important de suivre la cristallisation de cette image sous la plume d’un intellectuel à la fois très impliqué dans la politique roumaine et très critique envers elle, porteur, en même temps, d’une interrogation d’historien sur l’héritage de Rome dans les Balkans et sur les rapports qu’entretient l’Italie avec cette partie de l’Europe.

Published: September 2024

Comment enseigner le fait révolutionnaire avec la conflictualité démocratique qui lui est inhérente ? Qu’il s’agisse de la Révolution française, genevoise ou des décolonisations, le fait révolutionnaire a un potentiel antiautoritaire qui s’actualise lors de sa transmission dans le présent et qui en fait une question socialement vive (QSV). Cet article s’intéresse à ce que les prescriptions scolaires en France, en Suisse romande et au Cameroun prévoient en la matière, à l’influence que subissent ces prescriptions, et aux postures enseignantes quant aux possibilités d’engagement et de dévolution.
Marginal et fluctuant : l’enseignement de la contraception dans les professions prescriptrices en France
Authors: Fonquerne Leslie
Published: September 2024

Fondé sur une recherche doctorale en sociologie, cet article interroge la place de la contraception dans la formation des professions prescriptrices. L’analyse consiste en l’étude de cas d’un cours de médecine observé et d’un cours de maïeutique consulté, et s’appuie sur des entretiens menés auprès de membres du corps médical. Si l’enseignement en maïeutique tient compte du vécu des patientes, par contraste, la formation initiale des médecins traduit une appréhension strictement technique de la contraception, ancrée depuis plusieurs décennies. Le complément de formation en continu portant sur la contraception reste à l’initiative du personnel médical, dont l’expertise est assignée indépendamment de leur implication dans le processus de dévolution.
Neutralité ou discipline engagée ? Entre émancipation, dévolution et involution : les finalités de l’histoire scolaire en Suisse romande et leurs pressions sur le corps enseignant
Authors: De Mestral Aurélie
Published: September 2024

En portant un regard historique et didactique sur les transformations de la discipline scolaire histoire en Suisse romande, cet article questionne la neutralité de l’enseignement de l’histoire et les prétendus engagements souvent décriés des enseignant·es lorsqu’ils enseignent l’histoire dans une perspective émancipatrice. Au travers de l’étude des programmes en vigueur aux 19 e et 20 e siècles, il met en lumière les multiples finalités axiologiques assignées à la discipline et à ses protagonistes depuis sa constitution. Un examen plus particulier de la période de l’harmonisation romande (dans les années 1970) montre que le processus de transformation des plans d’études ambitionne une vraie révolution dans la transmission du savoir, mais se trouve aux prises avec une involution des valeurs. Cette étude témoigne donc du poids des finalités axiologiques et de l’involution auxquelles est soumise la discipline histoire , du rôle du corps enseignant dans son évolution, tout en montrant son caractère éminemment politique.

L’article 15 du règlement (CE) no 2201/2003 doit être interprété en ce sens que la juridiction d’un État membre compétente pour statuer sur le fond d’une affaire en matière de responsabilité parentale au titre de l’article 10 dudit règlement peut exceptionnellement demander le renvoi de cette affaire à une juridiction de l’État membre dans lequel cet enfant a été déplacé illicitement par l’un de ses parents. Les seules conditions auxquelles est subordonnée la possibilité du renvoi de l’affaire sont celles expressément énoncées à cette disposition. Lors de l’examen des conditions relatives à l’existence d’une juridiction mieux placée et à l’intérêt de l’enfant, la juridiction compétente au fond doit prendre en considération l’existence d’une procédure de retour engagée dans l’État membre où l’enfant a été illicitement déplacé par l’un de ses parents et qui n’a encore fait l’objet d’aucune décision définitive.

Background

Lumbar spine fractures are common injuries associated with substantial morbidity for patients and socioeconomic burden. This study sought to epidemiologically analyze lumbar spine fractures by mechanism of injury and identify temporal trends in patient demographics and disposition, which few studies have previously evaluated.

Materials and Methods

A retrospective analysis was done of the US National Electronic Injury Surveillance System (NEISS) database between 2003 and 2022. The sample contained all patients 2 to 101 years old with product-related lumbar fractures presenting to participating institutions' emergency departments. A total of 15,196 unweighted injuries (642,979 weighted injuries) were recorded.

Results

Overall, there was a 20-year incidence rate of 10.14 cases per 100,000 person-years with a 2-fold increase in fracture incidence. Females were more prone to lumbar fracture than males (
P
=.032). Injuries primarily stemmed from a fall (76.6%). The incidence of lumbar fracture increased most significantly in older patients, with patients 80 years and older showing the greatest annual increase (β=8.771,
R
2
=0.7439,
P
<.001) and patients 60 to 69 years showing the greatest percent increase with a 3.24-fold increase in incidence. Most (58.9%) of the fractures occurred at home. Females were more often injured at home compared with males (
P
<.001), who more often sustained lumbar fractures during recreational or athletic activity (
P
<.001). All patients older than 40 years showed at least a doubling in incidence rate of lumbar fracture between 2003 and 2022.

Conclusion

These data demonstrate the pressing need to address poor bone health in the aging population, shown here to have an increasing fracture burden. [

Published: September 2024

Background and Objective

To investigate visual outcomes for macula-off rhegmatogenous retinal detachments (RRD) compared to macula-on RRDs based on duration from diagnosis to surgical repair performed by a single surgeon with access to a retina call block system.

Patients and Methods

A case-control study reviewing the visual acuity (VA) after surgical repair in consecutive macula-off (
n
= 127) and maculaon (
n
= 63) RRD comparison eyes that underwent primary RRD repair performed by a single surgeon with dedicated retina call block time.

Results

Our results revealed significantly improved VA in macula-off RRD eyes repaired within 3 days of diagnosis at 3, 6, and 12 months/last follow-up, and that duration from diagnosis to surgery is a predictor of VA at 3- and 12-month/last follow-up postoperative visits.

Conclusion

Our findings support the use of mechanisms that improve access to operating room time, such as a retina call block system, to expedite surgical repair access.

A high-accuracy conservative numerical scheme for the generalized nonlinear Schrödinger equation with wave operator
Authors: Pan Xintian
Published: September 2024

In this article, we establish a novel high-order energy-preserving numerical approximation scheme to study the initial and periodic boundary problem of the generalized nonlinear Schrödinger equation with wave operator, which is proposed by the finite difference method. The scheme is of fourth-order accuracy in space and second-order one in time. The conservation property of energy as well as a priori estimate are described. The convergence of the proposed scheme is discussed in detail by using the energy method. Some comparisons have been made between the proposed method and the others. Numerical examples are presented to illustrate the validity and accuracy of the method.
Investigation of more solitary waves solutions of the stochastics Benjamin-Bona-Mahony equation under beta operator

Published: September 2024

This study explores the stochastic Benjamin-Bona-Mahony (BBM) equation with a beta derivative (BD), thereby incorporating multiplicative noise in the Itô sense. We derive various analytical soliton solutions for these equations utilizing two distinct expansion methods: the $ \frac{\mathcal{G}^{\prime}}{\mathcal{G}^{\prime}+\mathcal{G}+\mathcal{A}} $-expansion and the modified $ \frac{\mathcal{G}^{\prime}}{\mathcal{G}^{2}} $-expansion techniques, both within the framework of beta derivatives. A fractional multistep transformation is employed to convert the equations into nonlinear forms with respect to an independent variable. After performing an algebraic manipulation, the solutions are trigonometric and hyperbolic trigonometric functions. Our analysis demonstrates that the wave behavior is influenced by the fractional-order derivative in the proposed equations, thus providing deeper insights into the wave composition as the fractional order either increases or decreases. Additionally, we explore the effect of white noise on the propagation of the waves solutions. This study underscores the computational robustness and adaptability of the proposed approach to investigate various phenomena in the physical sciences and engineering.
Persistent de Rham-Hodge Laplacians in Eulerian representation for manifold topological learning
Authors: Su Zhe , Tong Yiying , Wei Guo-Wei
Published: September 2024

Recently, topological data analysis has become a trending topic in data science and engineering. However, the key technique of topological data analysis, i.e., persistent homology, is defined on point cloud data, which does not work directly for data on manifolds. Although earlier evolutionary de Rham-Hodge theory deals with data on manifolds, it is inconvenient for machine learning applications because of the numerical inconsistency caused by remeshing the involving manifolds in the Lagrangian representation. In this work, we introduced persistent de Rham-Hodge Laplacian, or persistent Hodge Laplacian (PHL), as an abbreviation for manifold topological learning. Our PHLs were constructed in the Eulerian representation via structure-persevering Cartesian grids, avoiding the numerical inconsistency over the multi-scale manifolds. To facilitate the manifold topological learning, we proposed a persistent Hodge Laplacian learning algorithm for data on manifolds or volumetric data. As a proof-of-principle application of the proposed manifold topological learning model, we considered the prediction of protein-ligand binding affinities with two benchmark datasets. Our numerical experiments highlighted the power and promise of the proposed method.
Linear generalized derivations on Banach $ ^* $-algebras
Authors: Ali Shakir , Hummdi Ali Yahya , Ayedh Mohammed , Rafiquee Naira Noor
Published: September 2024

This paper deals with some identities on Banach $ ^* $-algebras that are equipped with linear generalized derivations. As an application of one of our results, we describe the structure of the underlying algebras. Precisely, we prove that for a linear generalized derivation $ F $ on a Banach $ ^* $-algebra $ A $, either we obtain the existence of a central idempotent element $ e\in Q $, for which $ F = 0 $ on $ eQ $ and $ (1-e)Q $ satisfies $ s_{4} $, or the set of elements $ u\in A $ such that the identity $ [F(u)^n, F(u^*)^nF(u)^n]\in Z(A) $ holds for no positive integer $ n $ turns out to be dense. In addition to this we consider an identity satisfied by a semisimple Banach $ ^* $-algebra and look for its commutativity. Moreover, some related results are also established.

In India, although train accidents and derailments have come down, there has been a considerable increase in the number of accidents on unmanned railway level crossings in rural or remote areas. In this study, an intelligent railroad crossing alarm system (RailAlarm) is proposed using wireless sensor networks (WSN) to avert accidents at unmanned level crossings. The design of RailAlarm has three contributions: Firstly, a train detection mechanism has been built that triggers data in response to an approaching train. A second feature of RailAlarm is that a simple, stateless data transfer mechanism is used to forward the data to a sink and balance the power consumption. Thirdly, a novel sleep wakeup mechanism to conserve power has been designed which is a crucial feature in WSN. Based on a study of the model, the current RailAlarm design can be deployed with a maintenance interval of about once every 5 months, implying that all sensors are replaced only after 5 months with AA Batteries of 2500 mAh, after the expiry of their lifetime.

80Ni20Cr coatings produced by high-velocity oxygen fuel (HVOF) thermal spray technique are novel and widely used to improve the corrosion and wear resistance of metal and steel components in many applications, especially in coal-fired power plants. The present study investigated the effects of nano-Al2O3 at 0.5 wt.% on the microstructure of HVOF-sprayed 80Ni20Cr coating deposited on AISI 304L steels corresponding to its coating hardness. The coating was successfully sprayed with a thickness of 150 – 180 µm. The microstructure and phase formed by the coating were analyzed by a field emission electron microscope (FE-SEM) and an X-ray diffractometer (XRD). Synchrotron X-ray fluorescence spectroscopy (SRXRF) was used to confirm the Cr solid solution in the Ni-based coating. The presence of the nano-Al2O3 phase in the 80Ni20Cr coating was characterized by electron backscattered diffraction (EBSD). The nano-Al2O3 particles were homogenously distributed in the coating layers. The incorporation of nano-Al2O3 into 80Ni20Cr enhanced coating characteristics by decreasing surface roughness by 23% and increasing coating hardness by around 4%.
