Abstract
We collect a sample of 42 Type Ia supernovae (SNe Ia) with Swift UV photometry and well-measured early time light-curve rises and find that 2002es-like and 2003fg-like SNe Ia have different prepeak UV color evolutions compared to normal SNe Ia and other spectroscopic subtypes. Specifically, 2002es-like and 2003fg-like SNe Ia are cleanly separated from other SNe Ia subtypes by UVM2 − UVW1 ≳ 1.0 mag at t = − 10 days relative to B-band maximum. Furthermore, the SNe Ia that exhibit nonmonotonic bumps in their rising light curves, to date, consist solely of 2002es-like and 2003fg-like SNe Ia. We also find that SNe Ia with two-component power-law rises are more luminous than SNe Ia with single-component power-law rises at prepeak epochs. Given the similar UV colors, along with other observational similarities, we discuss a possible progenitor scenario that places 2002es-like and 2003fg-like SNe Ia along a continuum and may explain the unique UV colors, early time bumps, and other observational similarities between these objects. Ultimately, further observations of both subtypes, especially in the near-infrared, are critical for constraining models of these peculiar thermonuclear explosions.

Published: May 2024

Abstract
Transition disks, with inner regions depleted in dust and gas, could represent later stages of protoplanetary disk evolution when newly formed planets are emerging. The PDS 70 system has attracted particular interest because of the presence of two giant planets in orbits at tens of astronomical units within the inner disk cavity, at least one of which is itself accreting. However, the region around PDS 70 most relevant to understanding the planet populations revealed by exoplanet surveys of middle-aged stars is the inner disk, which is the dominant source of the system’s excess infrared emission but only marginally resolved by the Atacama Large Millimeter/submillimeter Array. Here we present and analyze time-series optical and infrared photometry and spectroscopy that reveal the inner disk to be dynamic on timescales of days to years, with occultation by submicron dust dimming the star at optical wavelengths, and 3–5 μm emission varying due to changes in disk structure. Remarkably, the infrared emission from the innermost region (nearly) disappears for ∼1 yr. We model the spectral energy distribution of the system and its time variation with a flattened warm (T ≲ 600 K) disk and a hotter (1200 K) dust that could represent an inner rim or wall. The high dust-to-gas ratio of the inner disk, relative to material accreting from the outer disk, means that the former could be a chimera consisting of depleted disk gas that is subsequently enriched with dust and volatiles produced by collisions and evaporation of planetesimals in the inner zone.
Pinwheel Outflow Induced by Stellar Mass Loss in a Coplanar Triple System

Published: May 2024

Abstract
We develop a physical framework for interpreting complex circumstellar patterns whorled around asymptotic giant branch (AGB) stars by investigating stable, coplanar triple systems using hydrodynamic and particle simulations. The introduction of a close tertiary body causes an additional periodic variation in the orbital velocity and trajectory of the AGB star. As a result, the circumstellar outflow builds a fine non-Archimedean spiral pattern superimposed upon the Archimedean spiral produced by the outer binary alone. This fine spiral can be approximated by off-centered circular rings that become tangent to each other at the location of the Archimedean spiral. The superimposed fine pattern fades out relatively quickly as a function of distance from the center of the system, in contrast to the dominant Archimedean spiral pattern, which presents a much slower fractional density decrease with radius. The different rates of radial decrease of the density contrast in the two superimposed patterns, coupled with their different time and spatial scales, lead to an apparent, but illusory radial change in the observed pattern interval, as has been reported, for example, in CW Leo. The function describing the detailed radial dependence of the expansion velocity is different in the two patterns, which may be used to distinguish them. The shape of the circumstellar whorled pattern is further explored as a function of the orbital eccentricity and the inner companion’s mass. Although this study is confined to stable, coplanar triple systems, the results are likely applicable to moderately noncoplanar systems and open interesting avenues for studying noncoplanar systems.
Chondrule Destruction via Dust Collisions in Shock Waves
Authors: Matsumoto Yuji , Kurosawa Kosuke , Arakawa Sota 
Published: May 2024

Abstract
A leading candidate for the heating source of chondrules and igneous rims is shock waves. This mechanism generates high relative velocities between chondrules and dust particles. We have investigated the possibility of the chondrule destruction in collisions with dust particles behind a shock wave using a semianalytical treatment. We find that the chondrules are destroyed during melting in collisions. We derive the conditions for the destruction of chondrules and show that the typical size of the observed chondrules satisfies the condition. We suggest that the chondrule formation and rim accretion are different events if they are heated by shock waves.
Evidence for Plasmoid-mediated Magnetic Reconnection during a Small-scale Flare in the Partially Ionized Low Solar Atmosphere

Published: May 2024

Abstract
Magnetic reconnection plays a crucial role in the energy release process for different kinds of solar eruptions and activities. The rapid solar eruption requires a fast reconnection model. Plasmoid instability in the reconnecting current sheets is one of the most acceptable fast reconnection mechanisms for explaining the explosive events in the magnetohydrodynamics (MHD) scale, which is also a potential bridge between the macroscopic MHD reconnection process and microscale dissipations. Plenty of high-resolution observations indicate that the plasmoid-like structures exist in the high-temperature solar corona, but such evidences are very rare in the lower solar atmosphere with partially ionized plasmas. Utilizing joint observations from the Goode Solar Telescope and the Solar Dynamics Observatory, we discovered a small-scale eruptive phenomenon in NOAA Active Region 13085, characterized by clear reconnection cusp structures, supported by nonlinear force-free field extrapolation results. The plasmoid-like structures with a size of about 150 km were observed to be ejected downward from the current sheet at a maximum velocity of 24 km s−1 in the Hα line wing images, followed by enhanced emissions at around the postflare loop region in multiple wavelengths. Our 2.5D high-resolution MHD simulations further reproduced such a phenomenon and revealed reconnection fine structures. These results provide comprehensive evidences for the plasmoid-mediated reconnection in partially ionized plasmas, and suggest a unified reconnection model for solar flares with different length scales from the lower chromosphere to the corona.

Méthode : Il s’agissait d’une étude descriptive et analytique réalisée auprès de 83 patients accidentés de la voie publique. Résultats : L’âge moyen était de 37 ans avec un sex ratio de 2,6 en faveur des hommes. La prévalence de la dépression chez les patients accidentés de la voie publique suivis au CNHU/HKM était de 80,72 %. Les facteurs associés à cette dépression étaient l’âge (p = 0.0366), les difficultés à honorer les soins (p = 0,0011) et l’indication ou la réalisation d’une prise en charge chirurgicale opératoire (p = 0,0041). Conclusion : Ces données montrent l’importance de la prévalence de la dépression chez les patients accidentés de la voie publique. La connaissance des facteurs associés à la dépression est primordiale pour une prise en charge adéquate des patients.
Beauté et modernité
Authors: Morel Journel Guillemette 
Published: May 2024

La catégorie du beau n’est guère de mise dans les arts et l’architecture d’aujourd’hui. Il y eut pourtant un épisode de l’histoire de l’architecture où un architecte s’est emparé de la beauté pour en faire frontalement un enjeu de la modernité, et ce au péril de sa réputation. En 1929, Le Corbusier répondit à ses détracteurs de la Neue Sachlichkeit (Nouvelle Objectivité), qui l’accusaient d’avoir conçu un projet académique pour le Mundaneum de Genève en forme de ziggourat, par un long texte significativement intitulé « Défense de l’architecture ». Un des slogans les plus marquants en était : « L’utile n’est pas le beau. » En n’hésitant pas à affronter de plein fouet l’ire de ses compagnons de route, Le Corbusier affirme que la beauté transcende les postures idéologiques et formalistes et garde, quels que soient les styles par lesquels elle est exprimée, une pertinence au cœur même du projet moderne.
Some Do Not… et No More Parades de Ford Madox Ford : l’impossible cartographie
Authors: Vialle Elisabeth 
Published: May 2024

Lorsque Ford Madox Ford entreprend la rédaction de sa tétralogie sur la Première Guerre mondiale, Parade’s End (1924-1928), c’est pour rendre compte de la violence faite aux corps des combattants et des civils, ainsi qu’à la terre et aux paysages européens alors que vacille l’ordre ancien. Parade’s End est traversé par la crise politique, épistémologique, esthétique qui ébranle l’Europe et trouve son expression dans l’image de la faille, de la béance, image géologique reprise au sein même d’un texte saisi par la fragmentation ou le dédoublement. À la question essentielle de la représentation et de l’aporie dont parlent Benjamin et Bataille, Ford répond par l’image de la carte (géographique ou militaire) sur laquelle tout repère a disparu : « The whole map of the embattled world ran out in front of him – as large as a field. An embossed map in papier mâché – a ten-acre field of embossed papier mâché […] ». Les cartes d’état-major qui ne disent plus que les villes et villages détruits, engloutis sous terre, se trouvent métaphoriquement reproduites à la surface d’un texte haché, troué, entrecoupé de silences qui sont également ceux de la mémoire lacunaire du personnage central, Christopher Tietjens. À partir de l’image saisissante du papier mâché, Ford superpose également une multiplicité de cartes symboliques dont le corps de Tietjens : point aveugle de sa conscience au début de la tétralogie, il est ignoré et invisible, comme absent de sa carte ontologique et incarne la fracture du monde et du sujet. Informe au sens propre du terme, il redevient, lors d’une expérience cathartique, solide, contenu, carte ultime enfin.
Failles et ruptures dans The Haunting of Hill House de Shirley Jackson (1959) et Mike Flanagan (2018) : le cri et l’irreprésentable
Authors: Cregut Céline 
Published: May 2024

Si l’adaptation audio-visuelle par Mike Flanagan du roman de Shirley Jackson The Haunting of Hill House, paru en 1959, peut surprendre par la manière dont elle dévie de la trame narrative originelle, Flanagan, par sa maîtrise des possibilités de l’image et du son, traduit parfaitement l’horreur qui est au cœur du roman. Les représentations du surnaturel, qui sont à la fois subtiles et très violentes dans The Haunting of Hill House, sont au cœur de la série que Flanagan a réalisée pour Netflix. Les questions centrales du roman, dont le surnaturel se fait la manifestation, y sont ainsi magnifiées au point où la narration semble parfois fendue, déchirée par la violence de l’image et du son. Ces failles (volontaires) dans la narration déjà fragmentée de la série permettent de révéler, ponctuellement, l’intensité de la détresse intime qui caractérisait déjà Eleanor, personnage principal du roman de Shirley Jackson, et que subit aussi Nell, son incarnation dans la série de Mike Flanagan. Bien loin d’un simple récit de fantômes et de maison hantée, tant le roman que son adaptation révèlent une horreur plus profonde et plus intime, celle d’une personne aliénée par le trauma, tout en exploitant les possibilités esthétiques et narratives du surnaturel. Ainsi, la série de Mike Flanagan offre un questionnement sur la représentation par le texte et l’image d’une détresse subjective et infigurable, et propose une solution (certes éphémère) à ce questionnement par un cri unique : une déchirure sensorielle de la narration qui s’opère par le recours momentané à un cri viscéral, situé au-delà de la logique et le langage. Ce cri poussé non pas par la protagoniste elle-même mais par un témoin de sa souffrance prouve ici la nécessité d’un recours à une représentation oblique de la détresse de Nell, et semble condenser, dans cette déchirure d’une narration alors temporairement suspendue, toute l’ampleur de l’horreur intime que le roman suggérait si subtilement.
Nucleic Acid Sensing by STING Induces an IFN-like Antiviral Response in a Marine Invertebrate

Published: May 2024

Abstract
The cytosolic detection of pathogen-derived nucleic acids has evolved as an essential strategy for host innate immune defense in mammals. One crucial component in this process is the stimulator of IFN genes (STING), which acts as a vital signaling adaptor, connecting the cytosolic detection of DNA by cyclic GMP-AMP (cGAMP) synthase (cGAS) to the downstream type I IFN signaling pathway. However, this process remains elusive in invertebrates. In this study, we present evidence demonstrating that STING, an ortholog found in a marine invertebrate (shrimp) called Litopenaeus vannamei, can directly detect DNA and initiate an IFN-like antiviral response. Unlike its homologs in other eukaryotic organisms, which exclusively function as sensors for cyclic dinucleotides, shrimp STING has the ability to bind to both double-stranded DNA and cyclic dinucleotides, including 2′3′-cGAMP. In vivo, shrimp STING can directly sense DNA nucleic acids from an infected virus, accelerate IFN regulatory factor dimerization and nuclear translocation, induce the expression of an IFN functional analog protein (Vago4), and finally establish an antiviral state. Taken together, our findings unveil a novel double-stranded DNA–STING–IKKε–IRF–Vago antiviral axis in an arthropod, providing valuable insights into the functional origins of DNA-sensing pathways in evolution.

Authors: Dinkar Karuna Shankar , Mittal Vivek , Kapoor Rajat , Sharma Brijesh , Saini Sushil Kumar , Verma Ashutosh 
Published: May 2024

Abstract

Background:
Fracture of calcaneum results in serious and prolonging disability. Considering the high rate of malunion and severe loss of function, it will be better to choose open reduction and internal fixation as a primary mode of treatment for calcaneum fractures.

Materials and Methods:
This study consists of 45 fractures of calcaneum treated by using close reduction and internal fixation and subtalar arthrodesis. Of the 45 fractures, 16 (35.56%) were treated by using the C-C screw within 2 weeks of injury and 29 (64.44%) were treated by using the percutaneous k-wire or Steinmann pin or C-C screw.

Results:
At the final follow-up, the mean AO foot and ankle score score of the patients was 89.28 with P value ≤ 0.0001.

Conclusion:
Early motion prevents stiffness of subtalar joint and ankle joint and leads to early function and psychological rehabilitation. Close reduction and internal fixation by using the C-C screw or Steinmann pin is a safe and effective method for treating displaced intra-articular fracture of calcaneum.

Published: May 2024

Abstract

Background:
Rehabilitation following anterior cruciate ligament (ACL) reconstruction is thought to be important by almost all surgeons. It has even been considered by some to be as important as surgery itself. As the surgical procedure for these injuries evolved, so has the rehabilitation. A traditional approach to rehabilitation which focused on delayed weight bearing and mobilization is now being replaced by accelerated rehabilitation which advocates early weight bearing and results in early return to sports.

Materials and Methods:
This is a observational case-control comparative study conducted in our department from September 2019 to February 2021. About 30 cases of more than 20 years of age with comparable matching group are included in our study. Assessment of Lysholm score, International Knee Documentation Committee (IKDC) score, ACL quality of life score, and Tegner activity level is done. Functional assessment was carried out by Carioca test, one leg hop test, and Shuttle test. Assessment of clinical status is done by anterior drawer test, Lachman test, and Pivot shift test.

Results:
All patients participating in study although nonathletic had complaints of instability and giving away episodes of knee in their day to day activities and therefore were considered as candidates for surgery. Following an arthroscopic ACL reconstruction, they were given written home-based protocols with goals and exercises being explained to them at the time of discharge. All the patients participating in the study were able to return to their preinjury activity level as assessed by the Tegner activity scale at the final follow up. Their functional outcome as measured by Lysholm score, IKDC score, and ACL quality of life score was significantly lower when compared to an age, sex, and activity matched control group. The patients functional performance as assessed by one leg hop test, Carioca test, and Shuttle test was also below the level of what was seen in control groups. More than 90% patients had a stable knee as assessed by the anterior drawer test, Lachman test and pivot shift test (29 patients has anterior drawer of ≤5 mm, 27 patients had Lachmann test ≤5 mm and all 30 patients had pivot shift grades in absent or glide category).

Conclusions:
Home-based rehabilitation is an effective method of rehabilitation in low demand individuals following ACL reconstruction. In the future, adequately powered randomized controlled trials are needed to assess the usefulness of one rehabilitation protocol over other in these group of low demand patients.
Bilateral osteochondroma in a child: A rare case report
Authors: Kumar Abhishek , Das Sarthak , Tripathy Saroj Kumar , Malik Archana 
Published: May 2024

Abstract
Osteochondroma has an incidence of 1 in 50,000 and is the most common benign bone tumor, which accounts for 30% (range 20%–50%) of all benign bone tumors. The incidence of osteochondroma is higher in males than females in both its solitary and hereditary forms. Osteochondroma can arise from any bone that develops from enchondral ossification. It commonly involves the long bones, and it rarely involves the ribs. Lesion is common in childhood, with 75%–80% occurring before the age of 20. Here, we report a case of bilateral rib osteochondroma that was presented during infancy.

Authors: Nair Parvathy G , Deep Valiyaparambil Chandran 
Published: May 2024

Abstract
This article presents the life profile of Manakoddam Keshavan Vaidyan—a Panchakarma expert from Kerala. We interviewed Vaidyan’s family members and acquaintances to collect more information about his life, mission, vision, and contributions to Ayurveda. He was an orator, patriot, social reformer, and gifted physician with in-depth knowledge of Panchakarma treatment. An attempt was also made to review his book, “Panchakarmam Athava Sodhana Chikitsa” and present its key specialties. This book may be one of the earliest works in Ayurveda, following a narrative medicine approach. He provides a detailed interpretation of Panchakarma concepts and tries to narrate the efficacy of these procedures through case reports from his clinical practice. The article provides insights into his life, mission, and role in strengthening Ayurveda in Kerala during pre- and post-independence periods.
