Published: April 2024

Abstract
M-type stars are crucial for stellar activity studies because they cover two types of magnetic dynamos and are particularly intriguing for habitability studies due to their abundance and long lifespans during the main-sequence stage. In this paper, we used the LAMOST DR9 catalog and the GALEX UV archive data to investigate the chromospheric and UV activities of M-type stars. All the chromospheric and UV activity indices clearly show that the saturated and unsaturated regimes, and the well-known activity–rotation relation, are consistent with previous studies. Both the FUV and NUV activity indices exhibit a single-peaked distribution, while the Hα and Ca ii H&K indices show a distinct double-peaked distribution. The gap between these peaks suggests a rapid transition from a saturated population to an unsaturated one. The smoothly varying distributions of different subtypes suggest a rotation-dependent dynamo for both early-type (partly convective) to late-type (fully convective) M stars. We identified a group of stars with high UV activity above the saturation regime (log

) but low chromospheric activity, and the underlying reason is unknown. By calculating the continuously habitable zone and the UV habitable zone for each star, we found that about 70% stars in the total sample and 40% stars within 100 pc are located in the overlapping region of these two habitable zones, indicating that a number of M stars are potentially habitable. Finally, we examined the possibility of UV activity studies of M stars using the China Space Station Telescope.

Abstract
Young protostellar binary systems, with expected ages less than ∼105 yr, are little modified since birth, providing key clues to binary formation and evolution. We present a first look at the young, Class 0 binary protostellar system R CrA IRAS 32 from the Early Planet Formation in Embedded Disks ALMA large program, which observed the system in the 1.3 mm continuum emission, 12CO (2−1), 13CO (2−1), C18O (2−1), SO (65−54), and nine other molecular lines that trace disks, envelopes, shocks, and outflows. With a continuum resolution of ∼0.″03 (∼5 au, at a distance of 150 pc), we characterize the newly discovered binary system with a separation of 207 au, their circumstellar disks, and a circumbinary disklike structure. The circumstellar disk radii are 26.9 ± 0.3 and 22.8 ± 0.3 au for sources A and B, respectively, and their circumstellar disk dust masses are estimated as 22.5 ± 1.1 M
⊕ and 12.4 ± 0.6 M
⊕, respectively. The circumstellar disks and the circumbinary structure have well-aligned position angles and inclinations, indicating formation in a smooth, ordered process such as disk fragmentation. In addition, the circumstellar disks have a near/far-side asymmetry in the continuum emission, suggesting that the dust has yet to settle into a thin layer near the midplane. Spectral analysis of CO isotopologues reveals outflows that originate from both of the sources and possibly from the circumbinary disklike structure. Furthermore, we detect Keplerian rotation in the 13CO isotopologues toward both circumstellar disks and likely Keplerian rotation in the circumbinary structure; the latter suggests that it is probably a circumbinary disk.
Magnetic Flux Plays an Important Role during a Black Hole X-Ray Binary Outburst in Radiative Two-temperature General Relativistic Magnetohydrodynamic Simulations

Published: April 2024

Abstract
Black hole (Bh) X-ray binaries cycle through different spectral states of accretion over the course of months to years. Although persistent changes in the Bh mass accretion rate are generally recognized as the most important component of state transitions, it is becoming increasingly evident that magnetic fields play a similarly important role. In this article, we present the first radiative two-temperature general relativistic magnetohydrodynamics simulations in which an accretion disk transitions from a quiescent state at an accretion rate of

. This huge parameter space in mass accretion rate is bridged by artificially rescaling the gas density scale of the simulations. We present two jetted BH models with varying degrees of magnetic flux saturation. We demonstrate that in “standard and normal evolution” models, which are unsaturated with magnetic flux, the hot torus collapses into a thin and cold accretion disk when

Phase and Morphology of Water-ice Grains Formed in a Cryogenic Laboratory Plasma
Authors: Nicolov André , Gudipati Murthy S. , Bellan Paul M. 
Published: April 2024

Abstract
Grains of ice are formed spontaneously when water vapor is injected into a weakly ionized laboratory plasma in which the background gas has been cooled to cryogenic temperatures comparable to those of deep space. These ice grains are levitated indefinitely within the plasma so that their time evolution can be observed under free-floating conditions. Using microscope imaging, ice grains are shown to have a spindle-like fractal structure and grow over time. Both crystalline and amorphous phases of ice are observed using Fourier transform infrared spectroscopy. A mix of crystalline and amorphous grains coexists under certain thermal conditions, and a linear mixing model is used on the ice absorption band surrounding 3.2 μm to examine the ice phase composition and its temporal stability. The extinction spectrum is also affected by inelastic scattering as grains grow, and characteristic grain radii are obtained from Mie scattering theory and compared to size measurements from direct imaging. Observations are used to compare possible ice nucleation mechanisms, and it is concluded that nucleation is likely catalyzed by ions, as ice does not nucleate in the absence of plasma and impurities are not detected. Ice grain properties and infrared extinction spectra show similarity to observations of some astrophysical ices observed in protoplanetary disks, implying that the fractal morphology of the ice and observed processes of homogeneous ice nucleation could occur as well in such astrophysical environments with weakly ionized conditions.

Abstract
We observe systematic profile changes in the visible pulsar of the compact double neutron star system PSR J1946+2052 using observations with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The interpulse of PSR J1946+2052 changed from a single-peak to a double-peak shape from 2018–2021. We attribute this evolution as the result of the relativistic spin precession of the pulsar. With the high sensitivity of FAST, we also measure significant polarization for the first time, allowing us to model this with the precessional rotating vector model. Assuming, to the first order, a circular hollow-cone-like emission beam pattern and taking the validity of general relativity (GR), we derive the binary’s orbital inclination angle (

). The quoted uncertainties do not reflect the systematic uncertainties introduced by our model assumptions. By simulating future observations of profile and polarization evolution, we estimate that we could constrain the precession rate within a 43% uncertainty in 9 yr. Hence, we suggest that the system’s profile evolution could be combined with precise pulsar timing to test GR in the future.

Abstract
We present the first observations of in situ electron acceleration at corotating interaction region (CIR) shocks near 1 au, utilizing measurements from Wind and Magnetospheric Multiscale (MMS) mission in the interplanetary medium. As the forward (reverse) shock of the 2018 January CIR (the 2020 February CIR) moves from Wind at [206, 92, −7]R

drift gets weaker (stronger) along the shock; both the upstream and shocked suprathermal electrons exhibit a flatter flux energy spectrum, while the electron shock acceleration becomes less (more) significant. For the shocked suprathermal electrons with significant flux enhancement, the flux ratio across the shock appears to peak in the direction perpendicular to the magnetic field. Therefore, the CIR shock acceleration of solar wind suprathermal electrons at 1 au exhibits an efficiency increasing with the

drift strength. These results also suggest that such acceleration through the interplanetary medium can contribute to the formation of solar wind suprathermal electrons.
De Sándor Ferenczi à Michael Balint : savoir clinique, éducation et formation
Authors: Pechberty Bernard 
Published: April 2024

Ferenczi nous oriente sur la question des liens entre psychanalyse et éducation. Dans une première partie, cet article décrit comment Ferenczi travaille, guidé par la clinique du traumatisme. Il nous transmet ses essais et erreurs, concernant les « techniques », liés à sa pratique psychanalytique. Il mobilise un rapport au savoir de recherche qui s’oppose frontalement à un savoir ritualisé dans la cure qui, de fait, reconduit la situation traumatique vécue par le patient. Dans un second temps, est étudié en quoi la formulation de la différence de l’enfant à l’adulte proposée par Ferenczi annonce la méthode que proposera Balint pour analyser en groupe la relation médecin malade. Ce premier type de dispositif clinique annonce les groupes cliniques d’analyse des pratiques professionnelles éducatives souvent développés en Sciences de l’éducation.
De Sándor Ferenczi à Salomon Resnik
Authors: Blanchard-Laville Claudine 
Published: April 2024

Dans ce texte, l’auteure se propose de revisiter son lien aux travaux de Sándor Ferenczi. En explorant ce qu’écrivent certains auteurs psychanalystes qui reconnaissent ouvertement se situer dans la ligne de l’héritage de Ferenczi, elle montre que certains autres, même si leurs travaux pourraient visiblement reconnaître une dette à son égard, ne le mentionne pas explicitement, vraisemblablement victimes de l’omerta dont ce psychanalyste a été la victime pendant une cinquantaine d’années. Claudine Blanchard-Laville montre comment elle-même a pu revisiter son propre lien à cet auteur à travers sa connaissance des travaux de Michael Balint et son usage du texte de 1932 de Ferenczi « Confusion de langue » ; et ce, au-delà de la transmission qu’elle a reçue de son analyste Salomon Resnik. Ce dernier n’a jamais fait allusion à son prédécesseur Ferenczi, alors même que son attitude clinique a de grandes proximités avec celle de Ferenczi et qu’il avait lui-même pour habitude de faire souvent allusion aux analystes qui l’avaient précédé et inspiré. L’article se termine par une évocation des travaux plus récents du psychanalyste Philippe Réfabert qui, lui, se relie ouvertement à Ferenczi après avoir analysé avec d’autres analystes certains éléments présents lors de la fondation par Sigmund Freud de la psychanalyse qui ont peut-être contribué à l’effacement ultérieur de l’œuvre de Ferenczi.

Published: April 2024

Purpose:
To describe amniotic membrane augmentation for enucleation after chemotherapy in retinoblastoma.

Methods:
This was a retrospective study of patients with retinoblastoma who underwent enucleation. The study also evaluated the utility of amniotic membrane grafting in enucleation after chemotherapy in eyes with retinoblastoma.

Results:

In this study, 110 eyes of 107 patients were analyzed, and 49 patients had previous systemic chemotherapy, 13 eyes had previous intra-arterial chemotherapy, and 7 eyes had external beam radiation. Amniotic graft was used in 8 eyes (5 following IAC, 2 following systemic chemotherapy, and 1 after both). After IAC, 3 of 7 eyes without amniotic graft had implant exposure compared to 0 of 6 eyes with amniotic graft (
P
= .05). Pathological examination of the conjunctiva after intra-arterial chemotherapy showed goblet cell hypoplasia that hinders wound healing.

Conclusions:
Amniotic membrane augmentation improves wound integrity in patients with retinoblastoma, especially following intra-arterial chemotherapy.

Evaluation of Structural and Functional Retinal Changes in Children With Intermittent Exotropia Versus Healthy Children
Authors: Ebeid Weam Mohamed , Abdellatif Mona Kamal , Mohsen Samak Noha 
Published: April 2024

Purpose:
To detect structural and functional changes in children with intermittent exotropia using optical coherence tomography, pattern electroretinography (ERG), and multifocal ERG.

Methods:

The study included 26 patients with intermittent exotropia and 26 healthy individuals matched for age and sex with a mean age of 9.23 and 11.20 years in the intermittent exotropia and control groups, respectively (
P
= .310). All patients underwent full ophthalmic examination including measurement of the angle of strabismus at near and far, and assessment of the macula and optic nerve using optical coherence tomography, pattern ERG, and multifocal ERG.

Results:
All patients had 6/6 best corrected visual acuity with no fixation preference. A significantly prolonged P and N wave latency was found in all measured rings of multifocal ERG of patients with intermittent exotropia, P wave amplitude was lower in rings 1 and 5, and N wave amplitude was lower in rings 1 and 2. Regarding pattern ERG, the amplitude of P50 wave was lower and N95 latency was prolonged in the intermittent exotropia group. The upper and lower ganglion cell complex and the superior retinal nerve fiber layer were significantly thinner in the intermittent exotropia group compared to controls.

Conclusions:
Children with intermittent exotropia without any associated amblyopia or refractive error showed a subnormal pattern and multifocal ERG response in addition to a thinner ganglion cell layer and retinal nerve fiber layer compared to normal controls. This signifies that subtle structural and functional retinal changes are found in patients with intermittent exotropia.

Essential to students’ intercultural learning abroad? Faculty intercultural development as key to leverage effective pedagogies
Authors: Sherman Whitney , Namaste Nina , Gibson Anne , Spira-Cohen Ezra 
Published: April 2024

In the realm of international education there are many calls to increase and improve faculty development to make study abroad experiences more intellectually and interculturally enriching, for both faculty and students (Anderson et al., 2016; Gillespie, 2019; Gillespie et al., 2020; Johnstone et al., 2020; Layne et al., 2020). In this study we analyze a particular faculty development structure as a model of effectiveness. Part of a larger study examining student learning on Council on International Educational Exchange (CIEE) programs, this article analyzes 22 educator interviews, specifically grouping and categorizing their stated pedagogical tactics, and found that this organization’s intentional, highly mentored, relationship-rich faculty development program—centered on their own intercultural learning and growth—helped educators leverage pedagogies to effectively foster students’ intercultural learning. We argue that faculty’s intercultural learning is the key to empowering faculty’s successful leveraging of dynamic pedagogies, not vice versa. Our study, thus, demonstrates the need for investment, expansion, and mentorship of integrated faculty development programming, particularly with regard to educators’ own intercultural growth, in order to implement effective pedagogies that activate and expand students’ deep learning, especially while studying abroad.
Examining SGIDs through a disability lens: Increasing awareness and access in a CTL program
Authors: Gravett Emily O. , Breneman Daisy L. 
Published: April 2024

Centers for teaching and learning (CTLs) have increasingly been attending to diversity, equity, inclusion, justice, and access (DEIJA), offering myriad programs for instructors to learn how to make their teaching more welcoming and effective for all students. Yet considerations of disability continue to lag behind in higher education, and educational developers themselves may not always create programs that are inclusive and accessible. In this article, we will focus on one popular CTL program, primarily called Small-Group Instructional Diagnosis (SGID) in the literature. When we examine this program through the lens of Disability Studies, we begin to realize just how much ableism permeates its design and implementation. This article will begin an important process of uncovering, naming, and detailing some of the overlapping barriers for those involved in the SGID process and the accompanying equity and access gap(s) that may inadvertently be created because SGIDs are so frequently offered across the United States. We will explore how we might respond to some of the limitations of the SGID program, as currently and commonly conceived, including turning to Universal Design for Learning (UDL) for redesign ideas and even considering whether this program continues to be the best way to achieve its intended outcomes. We offer a model for more broadly rethinking educational development processes that may perpetuate ableism and intersecting forms of oppression.
Association between healthy lifestyles and post-COVID-19 syndrome among college students
Authors: Sun Dezhuo , Zhu Xiangfei , Bao Zhonghan , Lin Xiaoping 
Published: April 2024

BACKGROUND:
Post-COVID-19 syndrome still occurs in some populations. A healthy lifestyle is widely recognized as a first-line treatment to increase the body’s antiviral resistance and tissue repair, but it is unclear whether a healthy lifestyle can promote or alleviate the symptoms of post-COVID-19 syndrome.

METHODS:
A stratified random sampling method was used to select 498 participants from three universities in Fujian as the target of the questionnaire survey. The survey focused on students’ healthy lifestyles and the symptoms of fatigue, anxiety, dyspnea, and depression that are common in post-COVID-19 syndrome.

RESULTS:
Two months after developing COVID-19, some students continued to experience fatigue, anxiety, dyspnea, and depression, with fatigue being the most prominent symptom. The results of the study showed that there was a significant negative correlation (P < 0.01) between a healthy lifestyle and fatigue, anxiety, dyspnea, and depression among university students. Furthermore, when analyzing the different subdimensions of healthy lifestyles among university students, it was found that all dimensions showed varying degrees of negative correlation with fatigue, anxiety, dyspnea, and depression, except for health-related behaviors and interpersonal behaviors, which showed no relationship with fatigue (P < 0.01).

CONCLUSIONS:
By improving healthy lifestyles, long-term COVID-19 symptoms can be reduced and improved and contribute positively to patient recovery, providing a viable rehabilitation option for long-term COVID-19 patients.
Adjuvant surgical resection for nontuberculous mycobacterial pulmonary disease: Effectiveness and complications
Authors: Kim Ji Yong , Yun Jae Kwang , Lee Geon Dong , Choi Sehoon , Kim Hyeong Ryul , Kim Yong-Hee , Park Seung-Il , Kim Dong Kwan 
Published: April 2024

BACKGROUND:
Standard antibiotic treatment for nontuberculous mycobacteria pulmonary disease (NTMPD) has unsatisfactory success rates. Pulmonary resection is considered adjunctive therapy for patients with refractory disease or severe complications, but surgical indications and extent of resection remain unclear. We present surgical treatment outcomes for NTMPD and analyzes risk factors for unfavorable outcomes.

METHODS:
We conducted a retrospective investigation of medical records for patients diagnosed with NTMPD who underwent surgical treatment at Asan Medical Center between 2007 and 2021. We analyzed clinical data including microbiological and surgical outcomes.

RESULTS:
A total of 71 NTMPD patients underwent thoracic surgery. Negative conversion of acid-fast bacillus (AFB) culture following pulmonary resection was observed in 51 (73.9%) patients. In terms of long-term outcomes, negative conversion was sustained in 38 cases (55.1%). Mortality occurred in 7 patients who underwent pulmonary resections for NTMPD. Statistically significant associations with factors for recurrence or non-negative conversion of AFB culture were found in older age (odds ratio [OR] =1.093, 95% confidence interval [CI]: 1.029–1.161, P = 0.004), male sex (OR = 0.251, 95% CI: 0.071–0.892, P = 0.033), and extensive NTMPD lesions involving three lobes or more (OR = 5.362, 95% CI: 1.315–21.857, P = 0.019). Interstitial lung disease (OR = 13.111, 95% CI: 1.554–110.585, P = 0.018) and pneumonectomy (OR = 19.667, 95% CI: 2.017–191.797, P = 0.018) were statistically significant risk factors for postoperative mortality.

CONCLUSION:
Pulmonary resection can be an effective adjuvant treatment option for NTMPD patients, with post-operative antibiotic treatment as the primary treatment. Careful patient selection is crucial, considering the associated risk factors and resectability due to complications and recurrence.
