Published: June 2024

Abstract
It is beneficial to calibrate the period–Wesenheit–metallicity relation (PWZR) of Delta Cephei stars (DCEPs), i.e., classical Cepheids, using accurate parallaxes of associated open clusters (OCs) from Gaia data release 3 (DR3). To this aim, we obtain a total of 43 OC–DCEPs (including 33 fundamental mode, 9 first overtone mode, and 1 multimode DCEPs) and calibrate the PWZR as

+ (−0.285 ± 0.064)[Fe/H]. The concurrently obtained residual parallax offset in OCs, zp = −4 ± 5 μas, demonstrates the adequacy of the parallax corrections within the magnitude range of OC member stars. By comparing the field DCEPs’ DR3 parallaxes with their photometric parallaxes derived by our PWZR, we estimated the residual parallax offset in field DCEPs as zp = −15 ± 3 μas. Using our PWZR, we estimate the distance modulus of the Large Magellanic Cloud to be 18.482 ± 0.040 mag, which aligns well with the most accurate published value obtained through geometric methods.
H i Lyα Emission from a Metal-poor Cool Stream Fueling an Early Dusty Starburst
Authors: Hall Kevin , Fu Hai 
Published: June 2024

Abstract
The GAMA J0913−0107 system is a rare conjunction of a submillimeter galaxy (SMG) at z ≈ 2.7 and two background QSOs with projected separations <200 kpc. Previous high-resolution QSO absorption-line spectroscopy has revealed high H i column density, extremely metal-poor (∼1% solar) gas streams in the circumgalactic medium of the SMG. Here we present deep optical integral-field spectroscopy of the system with the Keck Cosmic Web Imager (KCWI). Reaching a 2σ surface brightness limit ≈10−19 erg s−1 cm−2 arcsec−2 with ∼2 hr of integration time, we detect a filamentary Lyα nebula stretching ∼180 kpc from the SMG intercepting both QSO sightlines. This Lyα filament may correspond to the same cool gas stream penetrating through the hot halo seen in the absorption. In contrast to Lyα nebulae around QSOs, there is no obvious local source for photoionization due to the massive dust content. While uncertain, we consider the possibility that the nebula is ionized by shocks induced by the infall, obscured star formation, and/or a boosted UV background. The SMG–QSOs conjunction multiplied the efficiency of the KCWI observations, allowing a direct comparison of Lyα nebulae in two distinct environments. We find that the nebulae around the QSOs are much brighter and show steeper surface brightness profiles than the SMG nebula. This is consistent with the additional photoionization and Lyα scattering provided by the QSOs. While illustrating the challenges of detecting Lyα nebulae around SMGs, our work also demonstrates that important insights can be gained from comparative studies of high-z Lyα nebulae.
Fermi GBM Observations of the Galactic Magnetar SGR 1935+2154 during Its 2022 January Activity
Authors: Rehan Noor ul Sabah , Ibrahim Alaa I. 
Published: June 2024

Abstract
The X-ray and radio burst-emitting soft gamma-ray repeater SGR 1935+2154 has been the most active magnetar during the past decade, with at least one active episode each year since 2019. We report on the 2022 January activity as observed by the Fermi Gamma-Ray Burst Monitor and present the temporal and time-integrated spectral properties of the observed 112 X-ray bursts. No radio bursts were reported during the activity. The mean burst duration is comparable to most of the previous activities but is shorter than that of 2020, during which the magnetar emitted radio bursts. The mean burst spectrum is softer than the earlier activities and a long-term softening trend since 2016 is evident and is accompanied by a rise in the mean burst fluence and blackbody emission radii. The power-law indices of the

correlation also show an evolution during 2019–2022, where the soft component started becoming steeper, whereas the hard component shows a less steep trend. The burst properties show no significant evolution within the activity, which lasted for ∼ 45 days, and none of the observed bursts showed properties reminiscent of those of the hard, long X-ray counterpart to the 2020 fast radio burst FRB 200428 from the source. We discuss the results comparatively with the 8 yr history of the source since its discovery in 2014.
Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: Observational Characteristics in Different Regions of the Disks
Authors: Liu Jun-Rong , Wang Yi-Lin , Wang Jian-Min 
Published: June 2024

Abstract
Stars and compact objects embedded in accretion disks of active galactic nuclei (AGNs), dubbed accretion-modified stars (AMSs), often experience hyper-Eddington accretion in the dense gas environment, resulting in powerful outflows as the Bondi explosion and formation of cavities. The varying gas properties across different regions of the AGN disk can give rise to diverse and intriguing phenomena. In this paper, we conduct a study on the characteristics of AMSs situated in the outer, middle, and inner regions of the AGN disk, where the growth of the AMSs during the shift inward is considered. We calculate their multiwavelength spectral energy distributions (SEDs) and thermal light curves. Our results reveal that the thermal luminosity of the Bondi explosion occurring in the middle region leads to UV flares with a luminosity of ∼1044 erg s−1. The synchrotron radiation of Bondi explosion in the middle and inner regions peaks at the X-ray band with luminosities of ∼1043 and ∼1042 erg s−1, respectively. The γ-ray luminosity of inverse Compton radiation spans from 1042–1043 erg s−1 peaked at the ∼10 MeV (outer region) and ∼GeV (middle and inner regions) bands. The observable flares of AMS in the middle region exhibit a slow rise and rapid Gaussian decay with a duration of months, while in the inner region, it exhibits a fast rise and slow Gaussian decay with a duration of several hours. These various SED and light-curve features provide valuable insights into the various astronomical transient timescales associated with AGNs.

Published: June 2024

Abstract
C4H and c-C3H2, as unsaturated hydrocarbon molecules, are important for forming large organic molecules in the interstellar medium. We present mapping observations of C4H (N = 9−8) lines, c-C3H2 (J

Ka,Kb
= 21,2–10,1), and H13CO+ (J = 1−0) toward 19 nearby cold molecular cores in the Milky Way with the IRAM 30 m telescope. C4H 9–8 was detected in 13 sources, while c-C3H2 was detected in 18 sources. The widely existing C4H and c-C3H2 molecules in cold cores provide material to form large organic molecules. Different spatial distributions between C4H 9–8 and c-C3H2 2–1 were found. The relative abundances of these three molecules were obtained under the assumption of local thermodynamic equilibrium conditions with a fixed excitation temperature. The abundance ratio of C4H to c-C3H2 ranged from 0.34 ± 0.09 in G032.93+02 to 4.65 ± 0.50 in G008.67+22. A weak correlation between C4H/H13CO+ and c-C3H2/H13CO+ abundance ratios was found, with a correlation coefficient of 0.46, which indicates that there is no tight astrochemical connection between C4H and c-C3H2 molecules.
Martian Crustal Magnetic Field Effects on the Ionospheric Main Peak
Authors: Chen Yiding , Liu Libo , Le Huijun , Zhang Ruilong 
Published: June 2024

Abstract
Planetary magnetic fields can affect ionospheric plasma transport and coupling with the solar wind. In contrast to the terrestrial global magnetic field, there are only weaker and sporadic crustal magnetic fields on Mars. Many studies have indicated that Martian crustal fields can still modulate the topside ionosphere and its coupling with the solar wind. Nevertheless, it is unclear whether the crustal fields can affect the ionospheric main peak, which does not directly interact with the solar wind and is dominated by photochemical processes. In this study, the crustal field effect was identified from ionospheric measurements over unevenly distributed crustal fields. Both the intensity and configuration of the crustal fields were found to be capable of affecting the ionospheric main peak. The ionospheric peak electron density tends to decrease in the strong horizontal crustal field region. The results suggest that the crustal fields may affect the ionospheric main peak through modulating solar wind energetic particle precipitation; strong horizontal magnetic fields can partially prevent energetic particle precipitation and thus weaken impact ionization.
Continuing Home Oral Hypoglycemic Medications Was Associated With Superior Postoperative Glycemic Control Versus Initiating Sliding Scale Insulin After Total Hip Arthroplasty
Authors: Leal Justin , Wellman Samuel S. , Jiranek William A. , Seyler Thorsten M. , Bolognesi Michael P. , Ryan Sean P. 
Published: June 2024

Background:
This retrospective study investigated the impact of continuing vs discontinuing home oral hypoglycemic medications for patients with diabetes undergoing total hip arthroplasty.

Materials and Methods:
Patients who were not exclusively receiving home oral hypoglycemic regimens were excluded. Additionally, patients whose diabetes was not managed inpatient postoperatively were excluded. Included patients were retrospectively evaluated for early postoperative glycemic control, renal function, and metabolic abnormalities. Patients were then compared based on whether their home oral hypoglycemic regimen was continued vs discontinued in favor of initiating insulin while inpatient and analyzed using multivariable regression analysis.

Results:

A total of 532 patients undergoing total hip arthroplasty met inclusion criteria, with 78.6% continuing their home oral hypoglycemic regimen. Those who continued showed significantly lower median maximum inpatient blood glucose (178.5 mg/dL vs 249.5 mg/dL;
P
<.001) and median average inpatient blood glucose (138.4 mg/dL vs 178.6 mg/dL;
P
<.001). Linear regression analysis, adjusting for various potential confounding factors, revealed a positive correlation between discontinuation of home hypoglycemic medications and higher maximum in-patient blood glucose (β=70.15 [95% CI, 59.27–81.03];
P
<.001). Patients in the continuation group had lower proportions of acute kidney injury (18.7% vs 41.2%;
P
<.001) and metabolic acidosis (4.3% vs 17.5%;
P
<.001), along with a shorter length of stay (1.0 vs 2.0 days;
P
<.001).

Conclusion:

These findings suggest that continuing a home oral hypoglycemic regimen for patients with diabetes after total hip arthroplasty is associated with superior glycemic control without exacerbating renal abnormalities or increasing metabolic complications. [

Morceaux choisis. Le démantèlement sélectif des remparts de Cambrai à la fin du XIXe siècle
Authors: Roumegoux Yves 
Published: June 2024

Comme bien d’autres villes du pré carré, du moins celles qui en ont les moyens, la municipalité de Cambrai obtient, en 1892, le déclassement de la place par les autorités militaires. Le démantèlement des remparts, qui durera jusqu’en 1896, constitue une charge financière importante pour la ville, puisqu’elle représente alors près d’un cinquième des dépenses communales. En outre, les travaux sont freinés par de puissants mouvements d’opinion locaux, comme la Société d’Émulation de Cambrai, qui souhaitent sauvegarder le plus possible les vestiges du passé. Ainsi, certains éléments emblématiques de l’enceinte, tels que les portes, ont été conservés (la porte de Paris, datée de la fin du XIVe siècle, a été sauvée à une courte voix de majorité !) et transformés en « arcs de triomphes » glorifiant la ville et son passé, mais totalement coupés de leur contexte. Les tours, moins « recyclables », moins aptes à s’intégrer dans l’urbanisme nouveau, s’en sont moins bien sorties (la tour d’Abancourt est détruite en 1948 après avoir été rayée de l’inventaire des monuments historiques). La destruction sélective d’un ensemble fortifié, en conservant certains morceaux choisis, médiévaux de préférence, comme témoins du passé millénaire de la cité et de son identité, est en cela particulièrement exemplaire à Cambrai.
Béthune, aspects d’un démantèlement précoce au service d’une renaissance urbaine (1866-1878)
Authors: Machinet Léo , Manceau Christopher 
Published: June 2024

À la suite de son intégration définitive dans le royaume de France en 1713, la ville de Béthune perd progressivement son importance militaire. Les finances peinent à maintenir en état satisfaisant des fortifications qui apparaissent impossibles à adapter aux dernières évolutions de la poliorcétique. Au terme de cette stagnation, le déclassement de la place forte est prononcé par le décret du 26 juin 1867 permettant d’envisager le démantèlement de l’enceinte militaire. La particularité du cas béthunois réside dans sa précocité en comparaison avec les villes voisines. Une volonté de faire « table rase » pour faire entrer Béthune dans la modernité est incarnée par le maire d’alors, Charles Delisse-Engrand. Aujourd’hui, 150 ans après cette renaissance urbaine, quelques témoins d’enceinte demeurent çà et là, offrant un regard fugace sur leur aspect, mais aussi sur le décalage entre les intentions et la réalisation d’une démolition imparfaite. Le présent article propose un aperçu de la politique de démantèlement des fortifications de Béthune et des raisons variées quant à la survie de certains vestiges.
« Déceler l’accord entre parties dans les procès pour dette : un exemple de justice négociée à la fin du xvie siècle au tribunal des échevins de Nancy »
Authors: Pezzetta Jonathan 
Published: June 2024

La négociation occupe une place centrale dans la résolution des litiges sous l’Ancien Régime. Souvent, les tentatives des parties à s’accorder commencent avant que ne soient sollicitées les autorités judiciaires. Pendant un procès, les acteurs poursuivent leurs tractations en dehors de l’auditoire. La fin des négociations marque généralement la résolution du conflit, d’où un taux d’évaporation des affaires portées en justice très important. Paradoxalement, malgré l’omniprésence de la négociation dans les litiges, elle ne laisse que peu de traces dans les sources judiciaires. C’est le cas notamment de documents aussi vastes que les registres des causes du tribunal des échevins de Nancy, instance souveraine située au cœur de la capitale du duché de Lorraine. Ces recueils datés du xvie au début du xviie siècles contiennent tous les procès civils jugés annuellement par l’échevinage. Un registre se détache du lot : le registre en matière de contredits des années 1597 et 1598 qui ne contient que des affaires de saisies et de grosses dettes. Le présent article part de l’hypothèse que les intérêts réciproques entre créanciers et débiteurs dans ces affaires leur donnent davantage de raisons de parvenir à un consensus et donc de négocier que de ? Il s’agit d’explorer cette source et d’établir un protocole pour en déceler les traces d’accords.

Uncommon elegance: Nephrotic surprises in adult immunoglobulin A vasculitis
Authors: Gökten Dilara Bulut , Mercan Rıdvan 
Published: June 2024

Abstract:
Henoch–Schönlein purpura (HSP) is a form of small-vessel vasculitis caused by the accumulation of immune complexes containing immunoglobulin A antibodies. It is usually seen in childhood. When the disease is considered in terms of nephritis, its incidence in children is reported to be between 20% and 54%. Hematuria and nephritic proteinuria are common in the course of the disease. However, nephrotic proteinuria is extremely rare. This article presents the case of an individual who was diagnosed with HSP as an adult, characterized by vasculitis. The patient did not present with arthritis or arthralgia during follow-up but developed gastrointestinal bleeding. In particular, nephrotic proteinuria was observed during follow-up.
Achilles tendinopathy following severe acute respiratory syndrome coronavirus 2 infection and COVID-19 vaccination
Authors: Adwan Marwan , Asfour Hasan , Abuhelal Ayman 
Published: June 2024

Abstract:Musculoskeletal symptoms are commonly reported following SARS-CoV-2 infection, with fatigue, arthralgia, and myalgia being the most common manifestations. Severe cases may include conditions like arthritis and rhabdomyolysis. Similarly, post-vaccination musculoskeletal symptoms have been documented. However, tendinopathy, particularly Achilles tendinopathy, remains underreported in both contexts. We present two cases of Achilles tendinopathy, one following SARS-CoV-2 infection and the other post-vaccination, to highlight potential musculoskeletal complications associated with COVID-19 and vaccination. In the first case, a 48-year-old male developed bilateral ankle pain eight weeks after a confirmed COVID-19 infection. The second case involves a 27-year-old male who experienced sudden, intense left Achilles tendon pain following SARS-CoV-2 vaccination. Case 1: The 48-year-old patient exhibited bilateral ankle pain and swelling, with MRI confirming Achilles enthesitis. Laboratory tests showed elevated ESR and CRP, with other parameters within normal ranges. Treatment with sulfasalazine led to significant improvement. Case 2: The 27-year-old patient demonstrates Achilles tendon rupture post-vaccination. Detailed findings and treatment outcomes were discussed to emphasize the rarity and significance of this condition. These two cases underscore the need for awareness and further research on the relatively serious musculoskeletal complications like Achilles tendinopathy following COVID-19 infection and vaccination. Enhanced medical understanding is crucial for optimizing patient care and addressing potential side effects effectively.

There is a possible increase in solid neoplasms in patients with Behçet’s disease (BD). We describe a 31-year-old woman, of Turkish origin, with mucocutaneous BD, who developed abdominal pain and rectal bleeding soon after the birth of her second baby. Colonoscopy and biopsy lead to a diagnosis of adenocarcinoma of the sigmoid colon. The association between BD and neoplasms is discussed, emphasizing the importance of cancer surveillance in this patient population.
Efficacy of intravitreal injection of Ziv-aflibercept before vitrectomy for proliferative diabetic retinopathy
Authors: Nawar Amin E. , Alagorie Ahmed R. 
Published: June 2024

Purpose
The aim of this study was to evaluate the efficacy of intravitreal injection of Ziv-aflibercept before small-gauge pars plana vitrectomy compared to pars plana vitrectomy alone in eyes with advanced diabetic eye disease.

Patients and methods
This is a prospective, randomized, interventional study that enrolled 60 eyes of 46 patients with advanced diabetic eye disease between February 2019 and December 2020. Intravitreal Ziv-aflibercept injection was given in 30 eyes before vitrectomy, while the other 30 eyes served as the control group (without intravitreal injection). The recorded data included intraoperative bleeding, surgical time, endodiathermy use, iatrogenic retinal breaks, and incidence of postoperative vitreous hemorrhage at 1 week, 1 month, 3, 6, and 12 months postoperatively.

Results
Intraoperative bleeding was noted in 18 (60%) eyes in the study group compared to 26 (86.66%) eyes in the control group, with no statistically significant difference (P=0.39). However, grade 2 intraoperative bleeding was reported significantly less in the study group (eight eyes, 26.66%) than in the control group (20 eyes, 66.66%) (P=0.004). At least one intraoperative iatrogenic retinal break was detected in 10 (33.33%) eyes in the study group compared to 18 (60%) eyes in the control group (P=0.44). The mean surgical time was significantly shorter (51.67±7.30 min) in the study group than in the control group (63.17±10.16 min) (P<0.001). However, there was no statistically significant difference in the rate of postoperative vitreous hemorrhage between the study group and the control group at 1 week, 1, 3, 6, and 12 months, postoperatively (P>0.05).

Conclusion
Preoperative intravitreal Ziv-aflibercept significantly decreased the surgical time and reduced the rate of severe intraoperative bleeding during diabetic vitrectomy.
Treatment outcome in refractive accommodative esotropia
Authors: Al-Morsy Osama A. , Ramadan Ahmed E. , Abd-Elaal Asmaa I. , Dawoud Manar F. 
Published: June 2024

BackgroundAccommodative esotropia (ET) usually presents in preschool years. It is often intermittent, and the deviation is typically eliminated by controlling the accommodative effort with optical correction of hypermetropia.ObjectiveThe aim of this study was to document the clinical features and to assess the functional outcome in patients with refractive accommodative esotropia (RAE) in terms of amblyopia and binocular vision and to analyze the possible risk factors involving the development of amblyopia.Patients and methodsWe retrospectively reviewed the records of 60 patients diagnosed with fully accommodative esotropia (FAET). Multiple parameters were reviewed, including age of onset, age of initiation of treatment, initial and final cycloplegic refraction, distance and near deviation with and without glasses, stereoacuity, presence of anisometropia, and change in hyperopia.ResultsThe mean age of onset and age of initiation of treatment were 2.53±1.42 and 2.73±1.25 years, respectively. The mean spherical equivalent refraction at the initial visit was +5.36±1.48 diopters (D) in the right eyes and +5.62±1.43 D in the left eyes. Anisometropia was present in 33.33% of the patients. Fusion was achieved in 90% of the patients, with 38 (63.33%) patients having stereopsis ranging from 40–100 sec/arc and 22 (36.67%) having stereopsis between 100 and 200 sec/arc with the Titmus fly test. Amblyopia was reduced from 50% to 16.67%. Anisometropia was found to be the only statistically significant risk factor for the development of amblyopia (P<0.001). Hypermetropia showed a tendency either to remain stable or to increase over the first seven years of life and then tended to decrease.ConclusionMost of the patients with FAET have an excellent outcome in terms of visual acuity and binocular vision. Amblyopia is common among patients with RAE and the current management strategies resulted in marked reduction in the prevalence of amblyopia.
