Published: December 2024

Abstract
We report here the results obtained from a systematic optical photometric survey aimed at finding new compact binary millisecond pulsars (also known as “spiders”): the COmpact BInary PULsar SEarch. We acquired multiband optical images over 1 yr around 33 unidentified Fermi Large Area Telescope sources, selected as pulsar candidates based on their curved GeV spectra and steady γ-ray emission. We present the discovery of four optical variables coinciding with the Fermi sources 3FGL J0737.2−3233, 3FGL J2117.6+3725 (two systems in this field), and 3FGL J2221.6+6507, which we propose as new candidate spider systems. Indeed, they all show optical flux modulation consistent with orbital periods of 0.3548(5), 0.25328(6), 0.441961(2), and 0.165(4) days, respectively, with amplitudes ≳0.3 mag and colors compatible with companion star temperatures of 5000–6000 K. These properties are consistent with the “redback” subclass of spider pulsars. If confirmed as a millisecond pulsar, 3FGL J0737.2−3233 will be the closest known spider to Earth (

We also present and discuss other multiwavelength information on our spider candidates, from infrared to X-rays.

Abstract
During routine survey imaging, the reactivated Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE-R) serendipitously caught the Type II supernova SN 2023ixf in Messier 101 on the rise, starting day 3.6 through day 10.9, and again on the decline at late times from days 211 through 213 and days 370 through 372. We have considered these mid-IR data together with observations from the ultraviolet (UV) through the near-IR, when possible. At day 3.6 we approximated the optical emission with a hot, ∼26,630 K blackbody, with a notable UV excess inferred to result from strong supernova (SN) shock interaction with circumstellar matter (CSM). In the IR, however, a clear excess is also obvious, and we fit it with a cooler, ∼1620 K blackbody with a radius of ∼2.6 × 1015 cm, consistent with dust in the progenitor’s circumstellar shell likely heated by the UV emission from the CSM interaction. On day 10.8, the light detected was consistent with SN ejecta-dominated emission. At late times we also observed a clear NEOWISE-R excess, which could arise either from newly formed dust in the inner ejecta or in the contact discontinuity between the forward and reverse shocks, or from more distant pre-existing dust grains in the SN environment. Furthermore, the large 4.6 μm excess at late times can also be explained by the emergence of the carbon monoxide 1–0 vibrational band. SN 2023ixf is the best-observed SN II in the mid-IR during the first several days after the explosion and one of the most luminous such SNe ever seen.
Revisiting the Chemical Composition of WD 1145+017: Impact of Circumstellar Disk Contamination on Photospheric Abundances
Authors: Le Bourdais Érika , Dufour Patrick , Xu 许 Siyi 偲艺 
Published: December 2024

Abstract
We performed a chemical analysis of the asteroid-bearing white dwarf WD 1145+017 using optical and ultraviolet spectroscopic data from 25 epochs between 2015 and 2023. We present an updated gas disk model with improved opacity calculations and temperature profiles to properly account for all circumstellar absorption features. Incorporating these changes into our models, we identified at least 11 elements in the disk, including a detection of circumstellar Na. We detected 16 elements in the photosphere, including new detections of P, Co, and Cu. At 16 elements, WD 1145+017 ties GD 362 as one of the most polluted white dwarfs in terms of the number of elements detected. We find that both the disk and photosphere compositions align, to first order, with CI Chondrite. Our study underscores the importance of accounting for circumstellar absorption, as neglecting them leads to significant abundance errors. Additionally, the analysis of the disk’s opacity highlighted an ultraviolet flux reduction due to a pseudo-continuum due to an optically thick component. This result may affect previous analyses of other polluted white dwarfs, suggesting a need for revisiting some studies.

Published: December 2024

Abstract
Spectral line observations encode a wealth of information. A key challenge, therefore, lies in the interpretation of these observations in terms of models to derive the physical and chemical properties of the astronomical environments from which they arise. In this paper, we present pomme, an open-source Python package that allows users to retrieve 1D or 3D models of physical properties, such as chemical abundance, velocity, and temperature distributions of (optically thin) astrophysical media, based on spectral line observations. We discuss how prior knowledge, for instance, in the form of a steady-state hydrodynamics model, can be used to guide the retrieval process, and we demonstrate our methods on both synthetic and real observations of cool stellar winds.

Abstract
The Fe Kα fluorescence line emission in X-ray spectra is a powerful diagnostic tool for various astrophysical objects to reveal the distribution of cold matter around photoionizing sources. The advent of the X-ray microcalorimeter on board the XRISM satellite will bring new constraints on the emission line. We present one of the first such results for the high-mass X-ray binary Centaurus X-3, which is composed of an O-type star and a neutron star (NS). We conducted a 155 ks observation covering an entire binary orbit. A weak Fe Kα line was detected in all orbital phases at an equivalent width (EW) of 10–20 eV. We found for the first time that its radial velocity (RV) is sinusoidally modulated by the orbital phase. The RV amplitude is 248 ± 13 km s−1, which is significantly smaller than the value (391 km s−1) expected if the emission is from the NS surface, but is consistent if the emission takes place at the O star surface. We discuss several possibilities of the line production site, including the NS surface, O star surface, O star wind, and accretion stream from the O star to the NS. We ran radiative transfer calculation for some of them assuming spherically symmetric density and velocity profiles and an isotropic distribution of X-ray emission from the NS. None of them explains the observed EW and velocity dispersion dependence on the orbital phase, suggesting that more elaborated modeling is needed. In other words, the present observational results have the capability to constrain deviations from these assumptions.

Abstract
Using Parker Solar Probe data from orbits 8 through 17, we examine fluctuation amplitudes throughout the critical region where the solar wind flow speed approaches and then exceeds the Alfvén wave speed, taking account of various exigencies of the plasma data. In contrast to WKB theory for noninteracting Alfvén waves streaming away from the Sun, the magnetic and kinetic fluctuation energies per unit volume are not monotonically decreasing. Instead, there is clear violation of conservation of standard WKB wave action, which is consistent with previous indications of strong in situ fluctuation energy input in the solar wind near the Alfvén critical region. This points to strong violations of WKB theory due to nonlinearity (turbulence) and major energy input near the critical region, which we interpret as likely due to driving by large-scale coronal shear flows.

Abstract
Studying ancient fluvial landforms on Mars is essential for understanding the planet’s climate history and can provide valuable insights into the intensity and duration of liquid water activity. This research used an Earth-based model to constrain local estimates of fluvial activity at the Eberswalde crater delta on Mars and sharpen our understanding of the sedimentary record with novel grain size and sediment flux calculations at this site. Remote sensing methods were used to reconstruct in-channel processes and estimate the delta formation by sediment transported in intermittent flows over ∼71,500 yr. Such sustained hydrological activity may have once provided habitable conditions at Eberswalde.
“I used to sing with a wound in the soul/ And metres of pain/ Dying the floor”*: An Interview-Article on Poetry, Translation and the Performativity of Bodies with Dinha
Authors: Fracalanza Laura , Montesi Vanessa 
Published: December 2024

Abstract: Dinha (Maria Nilda de Carvalho Mota) is a Brazilian poet, performer, activist and academic from São Paulo. Her poetry lies in the delicate balance between the orality of the saraus – public literary gatherings that foreground bodies and poetic performances – and the graphic constellation of brackets and blank spaces in the written publications of her choreographically composed texts. The duality of her poetry challenges translation and raises important questions about positionality and aesthetic choices. How does Dinha use writing to recreate orality and exert pressure on it? In the movement from writing to reading and back, how does she dismember and reassemble the body in a different medium? And how can we, as intramedial, intercultural, white European translators, perform a similar task in the rendition of her work into a different language? Such are the questions populating our interview with the poet.
Paroles, images et gestes révoltés : l’œuvre avant-gardiste de Ketty La Rocca (1938-1976) comme expérience continuelle de l’altérité
Authors: Gangemi Rosanna 
Published: December 2024

Résumé : Aujourd’hui Ketty La Rocca (1938-1976) est considérée comme une des artistes italiennes conceptuelles et verbo-visuelles parmi les plus importantes des années 1960-1970. Depuis quelques années son travail est au centre d’un regain d’intérêt international, comme les nombreuses expositions et acquisitions muséales le confirment. La pierre angulaire de sa recherche, pionnière, complexe, articulée et cohérente, bien que nécessairement courte du fait de sa mort prématurée, est la réflexion sur une communication la plus authentique possible. Elle s’est confrontée à différents dispositifs de communication, les a associés et juxtaposés, en réalisant des œuvres hybrides, poly-matérielles et intermédiales. Révélant à travers ses œuvres des messages idéologiques cachés, elle a montré le pouvoir à la fois manipulateur et limité du langage. Si la condition subalterne de la femme a été un de ses thèmes politiques majeurs, la quête identitaire comme dialogue avec l’altérité a été son sujet existentiel par excellence. Sa manière de faire de l’art comme tentative d’appréhender la réalité et d’agir en conséquence, sans se laisser influencer par des appartenances sectaires, a caractérisé son travail dès ses débuts, constituant l’un de ses héritages les plus importants. Par le biais d’un entrelacement constant entre la parole et l’image, le signe et le corps, Ketty La Rocca a contribué à redéfinir le concept d’œuvre d’art en élargissant ses frontières et en refaçonnant le rapport entre l’émetteur et le récepteur. Selon ces perspectives, son œuvre dans sa globalité, jusqu’ici peu analysée par la critique, fera l’objet de ce propos.
Le sabbat et les fêtes juives, jours fériés du calendrier romain. Une victoire politique des juifs italiens à la fin de l’Antiquité
Authors: Nemo-Pekelman Capucine 
Published: December 2024

La constitution impériale du 26 juillet 412, que les médiévaux nomment Die Sabbato, fut un succès politique des juifs italiens. Elle eut pour origine l’offensive de chrétiens italiens qui avaient utilisé une procédure, celle de la citation en justice, pour piéger les juifs qui refusaient de se déplacer en justice les jours de sabbat et de fêtes, les exposant à une condamnation pour contumace. On verra que cette offensive s’inscrivait à un moment – entre le ive et le ve siècle – où les Églises de Rome et d’Italie développaient une pastorale qui donnait une nouvelle visibilité à la célébration dominicale ainsi qu’un calendrier martyrial destiné à combler tous les temps de l’année. Or cette entreprise rencontrait sur son chemin les traditions séculaires, en Occident, du sabbat et des fêtes juives. Enfin, nous examinerons comment le pouvoir impérial arbitra cette matière, en montrant que la décision de 412 renouait avec une ancienne tradition – remontant à des lois d’Auguste et de Constantin – qui avait été temporairement rompue sous le règne de Théodose Ier.
L’inclusion ambiguë des juifs dans les villes italiennes du Moyen Âge
Authors: Todeschini Giacomo 
Published: December 2024

Entre le xiie et le xve siècle, les juifs italiens ont été perçus différemment par les pouvoir italiens de l’Italie centro-septentrionale et par les pouvoirs des souverains gouvernant les royaumes de Naples et de Sicile. Dans le premier cas, les juifs ne sont pas reconnus comme formant des communautés juridiques : ils sont plutôt identifiés comme des sujets particuliers liés aux gouvernements locaux par des relations économiques multiples. Dans le second cas, au contraire, les chancelleries royales définissent les « juifs » comme des communautés liées au roi par des devoirs fiscaux. Cette situation complexe produit au nord et au centre de la péninsule une condition civique des juifs italiens marquée par l’incertitude de l’appartenance, donc par une citoyenneté précaire et toujours révocable, tandis que, dans le Midi, les juifs se trouvent dans une condition de dépendance directe du pouvoir du roi qui fait d’eux des sujets à la fois séparés et privilégiés. Dans les deux cas, l’inclusion des juifs dans le corps civique et politique est caractérisée par une ambiguïté qui aboutira, à la fin du xve siècle, à une définition du judaïsme comme « crime pourtant non punissable » et, au xvie siècle, à la ghettoïsation.
Godefroy de Bouillon a-t-il trouvé le Graal ? La première croisade et le « vase suspendu » d’Albert d’Aix
Authors: Besson Florian 
Published: December 2024

Albert d’Aix, l’un des chroniqueurs de la première croisade, décrit une relique placée au cœur du temple de Salomon, à Jérusalem, que les croisés auraient découverte lors de la prise de la Ville sainte en 1099 : un vase d’or contenant le sang du Christ. Ce Graal « avant la lettre » en dit long sur la manière dont le chroniqueur imagine et fantasme la Terre sainte, mais aussi dont il pense et met en scène la croisade, en général, et celle de Godefroy de Bouillon en particulier.

Introduction: Cerebral palsy (CP) is a group of permanent disorders of the development of movement and posture, causing activity limitation that is attributed to non-progressive disturbances that occurred in the developing fetal or infant brain.Objectives: To assess the effectiveness of Task-specific Trunk Movement Training (TTMT) exercise protocol in rehabilitation of infants and children with high predictive value of CP.Method: The research design was a single blind randomized control trial. Forty-six children were selected and randomized into control group (n=23) and intervention group (n=23). Control group was provided with routine exercises and intervention group was provided with routine exercises and TTMT exercise protocol. The intervention was provided for 3 months. At the first session (1st week) and end of third month, the outcome measure (gross motor function measure) was used by a blinded evaluator who is a physiotherapist and not an employee of the study centre. Results: The study shows improvement in both groups (intervention and control). The intervention group showed a significant improvement in 1st month and 2nd month compared to control group in gross motor function measure scale.Conclusions: TTMT is an effective exercise protocol for training trunk movements in infants and children with high predictive value of CP.
Leaving no one behind: Disability and HIV prevention, knowledge among adults in a population cohort in Uganda
Authors: Mugisha Joseph O. , Makanga Ronald , Kimono Beatrice W. , Kasamba Ivan 
Published: December 2024

Background: People with disability are a vulnerable population and are at a high risk of acquiring human immunodeficiency virus (HIV) infection.Objectives: We investigated the association between severity of disability and not having knowledge of any HIV prevention method among adults in Uganda.Method: Between January 2015 and December 2015, data were collected within a general population in Uganda, on six domains of disability based on the Washington Group Short Set on Functioning. In addition, routine data on socio-demographic factors and other HIV-related data were collected among adults aged 16 years and above. A continuum of functioning was developed: without disability, mild, moderate and severe. Bivariate and multivariate associations of disability and not knowing any HIV prevention method were fitted using logistic regression models.Results: A total of 3,331 adults (60.4% female) were included. Of these, 14.5% (n = 482) were classified as having either moderate or severe disability, and this proportion exponentially increased with age (p 0.001). Overall, 4.2% (n = 140) reported not knowing any HIV prevention method, with a slightly higher proportion among females than males (3.1% in males, 4.9% in females). Compared to people with no disability, those with moderate or severe disability were 5 times more unlikely to know any HIV prevention methods (adjusted odds ratio = 5.45, 95% confidence interval = 3.25 -9.13, p 0.001). Additionally, the combined effect of moderate and severe disability and none/incomplete primary education increased the likelihood of not knowing HIV prevention methods over and beyond their separate effects (p 0.001).Conclusion: Effective HIV prevention strategies must integrate best practices that target people with disabilities.Contribution: These findings contribute to the evidence of the lack of HIV prevention knowledge among people with disabilities in general populations.
Colonoscopy Participation Rate and its Determinants among First-Degree Relatives of Colorectal Cancer Patients: A Cross-sectional Study
Authors: Paul Teenu , Georgy Sneha , Saju C. R. , Jini M. P. 
Published: December 2024

Abstract

Introduction:
Colorectal cancer (CRC) is a significant global health concern. First-degree relatives (FDR) of colorectal cancer patients are at higher risk of developing the disease, emphasizing the importance of screening by colonoscopy. Screening behavior can be influenced by healthcare system-related and psychological factors. There is a scarcity of studies related to this in India.

Objectives:
We aimed to assess the participation rate in colonoscopy and its determinants among first-degree relatives of colorectal cancer patients.

Materials and Methods:
A cross-sectional study was conducted among 60 first-degree relatives of colorectal cancer patients in a tertiary care center in Kerala from February to August 2023 using a pre-validated questionnaire based on the health belief model (HBM). An interview was conducted, and data were analyzed using SPSS version 25.

Results:
Of the 60 first-degree relatives assessed, only 8% had undergone colorectal cancer screening by colonoscopy. Mean age at diagnosis of CRC in the index patient was 62 ± 8 years, while the mean age of FDRs at diagnosis was 45.53 ± 10.1 years. HBM variables, namely, perceived susceptibility, perceived benefits, and cues to action, were observed to have a statistically significant association with the uptake of the colonoscopy screening procedure. “Fear of the screening procedure” (38%) was the most frequently observed barrier for undergoing colonoscopy screening.

Conclusion:
Knowledge about the facilitators and barriers to screening behavior among first-degree relatives will help healthcare providers tackle the low screening rates and reduce the burden of colorectal cancer in these vulnerable populations.
Patient’s Perception in Sequential LASIK and PRK Surgeries: A Comparison of Fellow Eyes
Authors: Meena Ashok Kumar , Parmar Gautam Singh , Prasad Sonali , Nakra Sidharth 
Published: December 2024

Abstract

Purpose:
To analyze the patient’s perception in consecutive eyes undergoing photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) surgeries.

Settings:
This study was carried out in a tertiary care ophthalmic institute in central India.

Design:
This study was a prospective cohort study.

Materials and Methods:
Patients eligible for consecutive LASIK or PRK in both eyes were included. A complete ophthalmic evaluation, along with a preoperative anxiety Amsterdam Preoperative Anxiety and Information Scale (APAIS) score (range 6–30) and a postoperative pain Visual Analog Scale score (0–10), was performed by a trained investigator. Hemodynamic parameters were also measured.

Results:
A total of 101 patients were included in the LASIK group and 32 in the PRK group. Both patients were divided into group A, with the right eye operated on first, and group B, with the left eye operated on first. The mean pain score in LASIK patients in the second eye was 3.11 ± 2.12 (mean ± standard deviation) and 1.78 ± 1.83 in the first eye, and in PRK patients, it was 3.91 ± 2.29 in the second eye and 2.59 ± 2.55 in the first eye. About 67.3% in the LASIK group complained of more pain in the second eye compared with 56.25% in the PRK group. APAIS score comparison between the two eyes was not statistically significant among the two groups. The patients also showed a significant intraoperative change (P < 0.001) in systolic and diastolic blood pressures. No significant difference was seen between the intraoperative pulse, spherical equivalent, pachymetry, preoperative keratometry, or static cyclotorsion in the groups.

Conclusion:
Pain experienced in the second eye was more compared with the first eye, with a significant change in hemodynamics during second eye surgery in both LASIK and PRK patients.
