Cell cycle length governs heterochromatin reprogramming during early development in non-mammalian vertebrates
Authors: Fukushima Hiroto S , Ikeda Takafumi , Ikeda Shinra , Takeda Hiroyuki 
Published: June 2024

AbstractHeterochromatin marks such as H3K9me3 undergo global erasure and re-establishment after fertilization, and the proper reprogramming of H3K9me3 is essential for early development. Despite the widely conserved dynamics of heterochromatin reprogramming in invertebrates and non-mammalian vertebrates, previous studies have shown that the underlying mechanisms may differ between species. Here, we investigate the molecular mechanism of H3K9me3 dynamics in medaka (Japanese killifish, Oryzias latipes) as a non-mammalian vertebrate model, and show that rapid cell cycle during cleavage stages causes DNA replication-dependent passive erasure of H3K9me3. We also find that cell cycle slowing, toward the mid-blastula transition, permits increasing nuclear accumulation of H3K9me3 histone methyltransferase Setdb1, leading to the onset of H3K9me3 re-accumulation. We further demonstrate that cell cycle length in early development also governs H3K9me3 reprogramming in zebrafish and Xenopus laevis. Together with the previous studies in invertebrates, we propose that a cell cycle length-dependent mechanism for both global erasure and re-accumulation of H3K9me3 is conserved among rapid-cleavage species of non-mammalian vertebrates and invertebrates such as Drosophila, C. elegans, Xenopus and teleost fish.

Authors: Porth Lucas , Heydenreich Sven , Burger Pierre , Linke Laila , Schneider Peter 
Published: June 2024

Context. Third-order lensing statistics contain a wealth of cosmological information that is not captured by second-order statistics. However, the computational effort it takes to estimate such statistics in forthcoming stage IV surveys is prohibitively expensive.
Aims. We derive and validate an efficient estimation procedure for the three-point correlation function (3PCF) of polar fields such as weak lensing shear. We then use our approach to measure the shear 3PCF and the third-order aperture mass statistics on the KiDS-1000 survey.
Methods We constructed an efficient estimator for third-order shear statistics that builds on the multipole decomposition of the 3PCF. We then validated our estimator on mock ellipticity catalogs obtained from N-body simulations. Finally, we applied our estimator to the KiDS-1000 data and presented a measurement of the third-order aperture statistics in a tomographic setup.
Results. Our estimator provides a speedup of a factor of ∼100–1000 compared to the state-of-the-art estimation procedures. It is also able to provide accurate measurements for squeezed and folded triangle configurations without additional computational effort. We report a significant detection of tomographic third-order aperture mass statistics in the KiDS-1000 data (S/N = 6.69).
Conclusions. Our estimator will make it computationally feasible to measure third-order shear statistics in forthcoming stage IV surveys. Furthermore, it can be used to construct empirical covariance matrices for such statistics.

Published: June 2024

Context. To develop a more comprehensive picture of star formation, it is essential to understand the physical relationship between dense cores and the filaments embedding them. There is evidence that magnetic fields play a crucial role in this context.
Aims. We aim to understand how magnetic fields influence the properties and kinematics of an isolated filament located east of the Barnard 59 clump, within the Pipe Nebula.
Methods. We used near-infrared polarization observations to determine the magnetic field configuration, and we applied the Davis–Chandrasekhar–Fermi method to infer the magnetic field strength in the plane of the sky. Furthermore, we used complementary data from the James Clerk Maxwell Submillimetre Telescope of C18O and the 13CO J = 3–2 transition to determine the filament’s kinematics. Finally, we modeled the radial density profile of the filament with polytropic cylindrical models.
Results. Our results indicate that the filament is stable to radial collapse and is radially supported by agents other than thermal pressure. In addition, based on previous observations of emission lines on this source, we suggest that gas is flowing toward the hub, while C18O (3–2) nonthermal motions indicate that the cloud is in a quiescent state.
L’acquisition des expressions idiomatiques au-delà de la distance interlinguistique
Authors: Hu Huiyun 
Published: June 2024

L’apprentissage des expressions idiomatiques françaises (EI) représente souvent un défi pour les apprenants étrangers en raison de leur non-compositionnalité sémantique et de leurs contraintes syntaxiques. Cependant, toutes les EI ne présentent pas la même difficulté, et l’influence de la L1 des apprenants est un aspect crucial dans l’acquisition d’une langue étrangère. Des études antérieures ont montré que les connaissances des EI en L1 peuvent faciliter ou compliquer l’apprentissage des EI en L2. Cette recherche se penche sur la question de savoir si ces observations basées sur les langues indo européennes sont appliquables à des langues distantes, sans rapprochement linguistiques ou culturelles, comme c’est le cas entre le chinois et le français.
Pour mieux comprendre l’apprentissage des EI en L2 dans le cas où la L1 et la L2 sont éloignées, nous avons mené une étude expérimentale avec 39 apprenants chinois de niveau intermédiaire en français. Les résultats de cette étude suggèrent que, malgré l’éloignement entre les langues, l’équivalence interlinguistique joue un rôle dans l’efficacité de la compréhension et de la production des EI. Cependant, l’effet de ce facteur se manifeste de manière différente par rapport aux études sur des langues indo européennes, soulignant l’importance de prendre en compte les spécificités des langues distantes dans le processus d’apprentissage de ces expressions.
« Euphonie défective » et invariance verbale : approche lexico-morphologique
Authors: Léopold Julia 
Published: June 2024

Si nous avons toutes et tous appris, selon la grammaire scolaire, que la conjugaison française connaissait trois groupes verbaux (correspondant à trois macroclasses flexionnelles), l’essor récent du numérique, avec dans son sillage l’émergence du cyberlangage, a bousculé nos pratiques langagières. Il est en effet, aujourd’hui, des verbes jusqu’alors employés à l’oral qui, grâce à cette oralisation de l’écrit propre au "langage médié par ordinateur", sont désormais observables à l’écrit. Des verbes distincts d’un point de vue morphologique, étymologique ou sémantique, que la métalexicographie considère tous comme "invariables" et que nous qualifierons d’ "invariants" puisqu’ils présentent une isomorphie flexionnelle, non-marquée, pour les diverses cases de leur paradigme.
Quels sont ces verbes invariants, comment se conjuguent-ils et comment expliquer leurs particularités morphologiques ?
Dans cette étude, nous nous proposons d’abord de catégoriser ces verbes qui, malgré la disparité de leurs étymologies et, plus encore, de leurs flexions suffixales, entrent pourtant selon nous dans ce que nous appellerons une "macroclasse invariante". Des verbes en apparence invariables, nés d’une liberté de création lexicale mais dont l’emploi semble paradoxalement contraint. Il s’agira alors d’expliciter la méthodologie qui nous aura permis d’en sonder l’usage, dans un contexte de cyberlangage, afin de circonscrire et de définir la conjugaison de ces verbes. Une analyse comparative avec des verbes dont la flexion est régulière nous conduira à avancer des hypothèses quant à l’adéquation de l’infléchissabilité de ces verbes avec la typologie verbale holistique décrite par Bonami, et de mettre en lumière la défectivité propre à cette macroclasse. C’est ici que nous développerons le concept d’« euphonie défective », qui s’expliquerait par une tendance au « retour à la norme » induite par la recherche de schèmes prosodiques familiers.

Abstract
Objective Spermatozoa are susceptible to oxidative radicals when
antioxidant defenses are inadequate. The extent to which oxidative radicals
contribute to sperm damage in patients with acromegaly remains unclear. This
study aimed to investigate and elucidate this relationship.
Methods The overall status of oxidants and antioxidants in both seminal
plasma and serum of patients with acromegaly compared to a control group of
healthy individuals was investigated. In addition, sperm parameters, including
important measures such as growth hormone and insulin-like growth factor-1
concentrations.
Results Twenty-two patients with acromegaly with controlled disease and 14
healthy controls were included. The total oxidant status was significantly
higher in the semen samples of the patients with acromegaly. A negative
correlation was found between sperm total oxidant status and total sperm count
and sperm concentration. Similarly, a negative correlation was found between the
total sperm count and the sperm oxidative stress index. In individuals diagnosed
with acromegaly, there was a statistically significant increase in sperm growth
hormone levels. Conversely, the level of insulin-like growth factor 1 was
significantly increased in the sperm of the control group, which consisted of
healthy individuals. The correlation analysis revealed a significant
relationship between venous total oxidant status and growth hormone levels in
semen.
Conclusion The elevated levels of reactive oxygen radicals in individuals
with acromegaly suggest a possible link between oxidative stress and its effects
on semen quality.

Published: June 2024

AbstractThere has been an increase in the diagnosis of thyroid nodules in recent years.
In addition to the well-known criteria, features that are likely to increase the
risk of malignancy are in the research process. In this study, we aimed to
evaluate the malignant potential of nodules that expand the thyroid capsule
ultrasonographically. A total of 109 patients with thyroid capsule-expanding
nodules and 288 patients with non-expanding nodules were included in the study.
Demographical data, ultrasonography features, and cytology results were noted,
and histopathological findings were determined in operated patients. While
malignant cytology was detected in 5.5% of capsule-expanding nodules in FNAB
results, this rate was 0.7% in the non-capsule expanding group (p<0.001).
According to the histopathological results, the incidence of malignancy was
15.6% in the capsule-expanding nodule group, while it was 3.1% in the other
group (p=0.001). As a result of logistic regression analysis, it was determined
that the risk of malignancy increased by 4.44-fold (95% CI 1.4–13.8, p=0.01) in
patients with capsule-expanding nodules. Other features that increased the risk
of malignancy were hypoechogenicity, microcalcification, and irregular margin
presence. In this study, we found that the risk of malignancy increased in
nodules expanding the thyroid capsule. Based on the increasing study data on
this subject, monitoring thyroid capsule expansion in nodules may take its place
among the criteria for malignancy in future evaluations.
The Impact of High-Fidelity Simulator System on Bronchoscopy Operation Skills of Trainees Who Receive Refresher Training: A Teaching Study
Authors: Jin Guoping , Tao Xiaofen , Xu Hongzhen 
Published: June 2024

Abstract
Objective This study aimed to explore the impact of high-fidelity simulator (HFS) training on the bronchoscopy operation skills, confidence, stress, and learning satisfaction of trainees who further their training at endoscopy center in our hospital. The study also investigated the practical application effects of HFS training and provided a reference for the development of clinical teaching and training programs in hospitals.
Methods The 18 trainees who furthered their training at the endoscopy center were evaluated for their bronchoscopy operation skills, confidence, and stress levels before and after HFS training. A survey on learning satisfaction was conducted after the completion of HFS training. The scores of all evaluations were collected for comparison of differences before and after HFS training.
Results HFS training improved the clinical operation skill levels and confidence of trainees who further their training at the endoscopy center, reduced their stress, and achieved 100% satisfaction from this training. Education level and department had no significant impact on trainees' operational skills and confidence improvement, and stress reduction (p > 0.05). The results of this study supported the influence of the history of endoscopy operations on the improvement of trainees' improved operational skills after HFS training, but it had no relation to the improvement of confidence and stress reduction. Trainees with a history of endoscopy operations had higher operation skill scores before and after HFS training (n = 5, 94.80 ± 2.95 and 97.60 ± 1.82, respectively) than those without a history of endoscopy operations (n = 13, 80.62 ± 2.53 and 86.38 ± 2.82, respectively), and the difference was significant (p < 0.05).
Conclusion HFS training is an effective clinical teaching method that can significantly improve trainees' bronchoscopy operation skills and confidence, reduce stress, and achieve high levels of satisfaction.
The influence of linguistic and cognitive background on word stress processing in an unknown language
Authors: Schwab Sandra , Etter Faustine , Kamber Julie , Mouthon Michael , Rogenmoser Lars , Jost Lea B. , Annoni Jean-Marie 
Published: June 2024

Abstract
Individual differences in working memory and musical aptitude, as well as task complexity are crucial in
predicting the performance of word stress perception in a second language (L2). The present study investigated the interactive
effects of these factors with the listeners’ first language. French and German listeners, both without knowledge of Spanish,
performed stress-related tasks in Spanish, as well as musical and working memory tests in their L1. Besides confirming the impact
of L1, our findings better define the influence of working memory and musical aptitude on L2 stress perception by specifically
tapping into the central executive component of working memory, objectively assessing musical aptitude, and considering task
complexity as a moderating factor in the relationship between the inter-individual factors and L2 stress perception. Our findings
are also the first to demonstrate task-specific performance differences between French and German listeners, possibly reflecting
differential cognitive and perceptual mechanisms depending on L1.
Low-resolution prior equilibrium network for CT reconstruction
Authors: Yang Yijie , Gao Qifeng , Duan Yuping 
Published: June 2024

Abstract
The unrolling method has been investigated for learning variational models in x-ray computed tomography. However, for incomplete data reconstruction, such as sparse-view and limited-angle problems, the unrolling method of gradient descent of the energy minimization problem cannot yield satisfactory results. In this paper, we present an effective CT reconstruction model, where the low-resolution image is introduced as a regularization for incomplete data problems. In what follows, we utilize the deep equilibrium approach to unfolding of the gradient descent algorithm, thereby constructing the backbone network architecture for solving the minimization model. We theoretically discuss the convergence of the proposed low-resolution prior equilibrium (LRPE) model and provide the necessary conditions to guarantee its convergence. Experimental results on both sparse-view and limited-angle reconstruction problems are provided, demonstrating that our end-to-end LRPE model outperforms other state-of-the-art methods in terms of noise reduction, contrast-to-noise ratio, and preservation of edge details.
Interlayer coupled domain wall dynamics induced by external magnetic field in synthetic antiferromagnets
Authors: Hadjoudja Amina , Garcia-Sanchez Felipe , Lopez-Diaz Luis 
Published: June 2024

Abstract
The response of a magnetic domain wall to an external magnetic field in a perpendicularly magnetized synthetic antiferromagnet is studied using both micromagnetic simulations and a reduced model. It is found that the external field induces a sizable displacement between the position of the domain wall in each layer, which can be larger than the domain wall width for a sufficiently strong field. We also study the dynamic evolution of the system when this field is applied or removed. In both cases we find a complex response with two distinct phases that involve both internal domain wall rotation and coupled interlayer domain wall oscillations. As a result of this dynamics spin waves are radiated. The emitted radiation is characterized by a broadband spectrum and can be detected far away from the domain wall.
Tunable plasmon-induced transparency in anisotropic graphene-black phosphorus photonic device for high-performance sensors and switchers
Authors: Wang Zhe , Xie Juan , Fan Chunzhen 
Published: June 2024

Abstract
A novel photonic device composed of graphene and black phosphorus (G-BP) has been proposed, which achieves high-performance plasmon-induced transparency (PIT) effect within the THz range and maintains substantial tunability and anisotropy. The anisotropy of the PIT effect arises from the near-field coupling between two bright modes characterized by distinct effective electron masses of BP, resulting transparency window at 33.35 THz for TE polarization and at 26.92 THz for TM polarization. Through the modulation of Fermi energy in graphene, doping levels of BP and geometric parameters separately, a tunable transparency window is achieved. Notably, the convergence or divergence of the anisotropic transparency windows can be well manipulated with different BP doping levels. Furthermore, the proposed G-BP photonic device exhibits a high sensitivity to changes in the surrounding refractive index and substrates, with a maximum sensitivity of 12.04 THz/RI, rendering it suitable for sensor applications. Overall, the proposed photonic device exhibits notable PIT effects characterized by high anisotropic performance, substantial tunability, great sensitivity, and stability, making it a promising candidate for applications in sensors, polarizers, and switchers.
Chiral edge transport along domain walls in magnetic topological insulator nanoribbons
Authors: Pournaghavi N , Canali C M 
Published: June 2024

Abstract
Quantum anomalous Hall insulators are topologically characterized by non-zero integer Chern numbers, the sign of which depends on the direction of the exchange field that breaks time-reversal symmetry. This feature allows the manipulation of the conducting chiral edge states present at the interface of two magnetic domains with opposite magnetization and opposite Chern numbers. Motivated by this broad understanding, the present study investigates the quantum transport properties of a magnetized

topological insulator nanoribbon with a domain wall (DW) oriented either parallel or perpendicular to the transport direction. Employing an atomistic tight-binding model and a non-equilibrium Green’s function formalism, we calculate the quantum conductance and explore the nature of the edge states. We elucidate the conditions leading to exact conductance quantization and identify the origin of deviations from this behavior. Our analysis shows that although the conductance is quantized in the presence of the horizontal DW, the quantization is absent in the perpendicular DW case. Furthermore, the investigation of the spin character of the edge modes confirms that the conductance in the horizontal DW configuration is spin polarized. This finding underscores the potential of our system as a simple three dimensional spin-filter device.
Implementation of excellent spin-filtering effect in half-metallic electrode-based single-molecule optoelectronic devices
Authors: Zhu Guojia , Li Weili , Zhang Yanning 
Published: June 2024

Abstract
The application of half-metallic materials in single-molecule optoelectronic devices opens a promising way in advancing device performance and functionality, thus addressing a research question of significance. Here we propose a series of single-molecule devices with half-metallic FeN4-doped armchair graphene nanoribbon as electrodes and metalloporphyrin (MPr) molecules as photoresponsive materials for photon harvesting, which are driven by photogalvanic effects (PGEs). Through the quantum transport simulations, we systematically investigated the spin-polarized photocurrents under the linearly polarized light illumination in these devices. Since the exclusive opening only exists in the spin-up channel of the half-metallic nanoribbons, these devices can generate a large photocurrent in the spin-up direction whereas suppressing the spin-down photocurrent. Consequently, they exhibit an effective spin-filtering effect at numerous photon energies. Our study unveils the excellent spin-filtering effect achieved in single-molecule optoelectronic devices with half-metallic electrodes, showing instructive significance for the future design of new optoelectronic devices.
