Frequent variations and phylogenetic relationships within the genus Secale identified by ND-FISH according to the genome-wide universal oligonucleotides chromosome probes
Authors: Li Zhi , Sun Zixin , Ren Tianheng 
Published: December 2024

IntroductionRye (Secale cereale L.) played a very important role in wheat genetic improvement and forage production worldwide. However, since rye is a kind of cross-pollinated plant, high levels of genetic heterozygosity and heterogeneity existed in the genome. Genome-wide variation in repeat sequences is one of the most important reasons for chromosome evolution in rye. High-precision cytological identification can effectively identify the heterochromatin or repeat sequence variations in the rye genome, and the relationship between different rye varieties can be identified while obtaining the FISH-karyotype of different rye varieties. The evolution of rye chromosomes can be analyzed by the variation degree of different probes on rye chromosomes.MethodsAll materials were identified by non-denaturing fluorescence in situ hybridization (ND-FISH). Five probes, (AAC)6, Oligo-pSc119.2-1, Oligo-pTa71A-2, Oligo-pSc200, and Oligo-pSc250 were used to identify rye chromosomes.Results15 rye varieties including S. cereale (cultivated rye and weedy rye), S. strictum (wild rye), S. sylvestre (wild rye), and S. vavilovii (wild rye) were examined by five oligonucleotides probes. 92 signal sites and 2074 signal patterns were observed, suggesting that high polymorphisms exist in the different rye genomes. The karyotypes of 15 rye varieties were obtained, the frequency of different signal types at each signal site was calculated and the model diagrams of probes (AAC)6, Oligo-pSc119.2-1, Oligo-pTa71A-2, Oligo-pSc200 + Oligo-pSc250 were drawn. The results showed that the rate of variation of different chromosomes of rye was not consistent. 1R, 6R, and 7R have higher variation and genetic diversity, while 2R and 3R have lower variation and are more conserved relative to other chromosomes. The results also indicated that S. sylvestre has a far genetic distance from other rye species, and S. vavilovii might be one of the ancestors of Chinese rye varieties.DiscussionResults from this study confirmed rapid chromosome change and high levels of chromosome diversity in rye.

IntroductionTest anxiety, a prevalent psychological issue among medical students, can profoundly impact their social, behavioral, and emotional development. This condition is significantly associated with challenges in emotional regulation, and to date, no effective clinical treatment has been established to address it. This study aimed to investigate the potential benefits and effects of group impromptu music therapy (GIMT) on enhancing emotional regulation skills and alleviating test anxiety in medical students.MethodsA total of 29 participants in the experimental group and 30 participants in the control group were finally included for data analysis. Four weeks prior to the final exams, the experimental group commenced GIMT treatment, while the control group did not receive any intervention. Following the four-week intervention period, both groups were assessed using standardized scales and follow-up semi-structured interviews.ResultsThe results revealed that students given the GIMT intervention reported significantly lower levels of test anxiety, as measured by the Test Anxiety Scale (TAS), and experienced fewer difficulties with emotional regulation, as indicated by the Difficulties in Emotion Regulation Scale (DERS). Additionally, these students achieved higher examination scores than the control group. Qualitative data from semi-structured interviews further supported these observations.DiscussionCollectively, these findings demonstrate that GIMT is an effective method for enhancing the emotional regulation abilities of medical students and for relieving the symptoms of test anxiety, ultimately resulting in better academic performance. The study also indicates that GIMT could be a promising clinical auxiliary method for dealing with test anxiety and should be considered for inclusion in the curriculum of healthcare professional education programs. Nonetheless, more efforts are needed to address the limitations of this method before it can be widely used for clinical practice.
Prevention and control of infectious disease transmission in subways: an improved susceptible–exposed–infected–recovered model

Published: December 2024

IntroductionA well-connected transportation network unites localities but also accelerates the transmission of infectious diseases. Subways—an important aspect of daily travel in big cities—are high-risk sites for the transmission of urban epidemics. Intensive research examining the transmission mechanisms of infectious diseases in subways is necessary to ascertain the risk of disease transmission encountered by commuters.MethodsIn this study, we improve the susceptible–exposed–infected–recovered (SEIR) model and propose the susceptible–exposed–infected–asymptomatic infected (SEIA) model. First, we added asymptomatic patients to the improved model as a parameter to explore the role of asymptomatic patients in the transmission of infectious diseases in a subway. The numbers of boarding and alighting passengers were added to the model as two time-varying parameters to simulate the exchange of passengers at each station.ResultsThe improved model could simulate the transmission of infectious diseases in subways and identify the key factors of transmission. We then produced an example of the transmission of coronavirus disease (COVID-19) in a subway using real subway passenger data substituted into the model for the calculations.DiscussionWe ascertained that the number of exposed people continuously increased with the operation of the subway. Asymptomatic patients had a greater impact on the transmission of infectious diseases than infected people in the course of transmission. The SEIA model constructed in this study accurately determined the spread of infectious diseases in a subway and may also be applicable to studies on the transmission of infectious diseases in other urban public transport systems.

Published: December 2024

This paper introduces a Coriolis mass flow and density sensor. The sensor is made using Surface Channel Technology (SCT) but with selective wet etching to create the channels. This method forms suspended microfluidic channels with a larger cross-sectional area. Because of this larger cross-sectional area, the sensor has a much higher flow range, up to 50 g h−1 (for water) with a pressure drop of 1 bar, compared to the standard SCT-based Coriolis sensor, which is only 1.2 g h−1. The channel has a semi-elliptical cross-sectional area, measuring 200 micrometers wide and 70 micrometers deep. The channel wall is made of a stack of thin films with a total thickness of 2.5 μm. Water, isopropyl alcohol (IPA), and nitrogen (N2) are used to test and evaluate the sensor’s mass flow and density sensing performance.

Deep Learning–based Measurement of Planetary Radial Velocities in the Presence of Stellar Variability
Authors: Colwell Ian , Timmaraju Virisha , Venkataram Hamsa Shwetha , Wise Alexander 
Published: December 2024

Abstract
We present a deep learning–based approach for measuring small planetary radial velocities (RVs) in the presence of stellar variability. We use neural networks to reduce stellar RV jitter in 3 years of HARPS-N Sun-as-a-star spectra. We develop and compare dimensionality-reduction and data-splitting methods, as well as various neural network architectures including single-line convolutional neural networks (CNNs), an ensemble of single-line CNNs, and a multiline CNN. We inject planet-like RVs into the spectra and use the network to recover them. We find that the multiline CNN approach is able to recover 50 day period planets with 0.2 m s−1 semiamplitude, with 8.8% error in the amplitude, compared to 80% error in the amplitude using a traditional cross-correlation function approach. This approach shows promise for mitigating stellar RV variability and enabling the detection of small planetary RVs with unprecedented precision.

Abstract
This paper addresses, for the first time, a key aspect of the phenomenology of compact symmetric objects (CSOs): the characteristics of their radio spectra. We present a radio-spectrum description of a complete sample of high-luminosity CSOs (CSO-2s), which shows that they exhibit the complete range of spectral types, including flat-spectrum sources (α ≥ −0.5), steep-spectrum sources (α < −0.5), and peaked-spectrum sources. We show that there is no clear correlation between spectral type and size, but there is a correlation between the high-frequency spectral index and both object type and size. We also show that, to avoid biasing the data and to understand the various classes of active galactic nuclei (AGN) involved, the complete range of spectral types should be included in studying the general phenomenology of compact jetted AGN, and that complete samples must be used, selected over a wide range of frequencies. We discuss examples that demonstrate these points. We find that the high-frequency spectral indices of CSO-2s span −1.3 < α
hi < −0.3 and hence that radio spectral signatures cannot be used to discriminate definitively between CSO-2s, binary galactic nuclei, and millilensed objects, unless they have α
hi > −0.3.
The Alignment of High-resolution Solar Prominence Images Observed by the New Vacuum Solar Telescope

Published: December 2024

Abstract
High spatial resolution observation of solar prominence is an important observation subject of the New Vacuum Solar Telescope (NVST). While the current level of observation and image reconstruction technologies for solar prominences are advanced, a significant challenge remains in achieving high-precision alignment among high-resolution prominence images observed at different times and different off-bands. Existing alignment approaches either become ineffective or yield low accuracy, and always require manual intervention during the alignment. These limitations are largely due to the stronger edge gradient and lower structural contrast of the prominence images compared with the solar surface ones. In response to this challenge, our study aims to develop an effective and robust algorithm for high-precision alignment of the prominence images. We thoroughly consider the unique structural characteristics of prominence images and the specific application conditions of various alignment algorithms. Consequently, we propose a comprehensive alignment method that incorporates the optical flow field of the solar surface, the gradient of the solar edge, and the cross-correlation within the solar prominence region. This method is designed to accurately determine the movement displacements among the prominence images. Our results demonstrate that this alignment method excels in both accuracy and robustness, making it well-suited for handling the diverse postures of solar prominence images captured by the NVST.
A Dust Attenuation Model Inspired by the NIHAO-SKIRT-Catalog
Authors: Faucher Nicholas , Blanton Michael R. 
Published: December 2024

Abstract
We use simulated attenuation curves from the NIHAO-SKIRT-Catalog to test the flexibility of commonly used dust attenuation models in the face of the variations expected from realistic star–dust geometries. Motivated by lack of flexibility in these existing models, we propose a novel dust attenuation model with three free parameters that can accurately recover the simulated attenuation curves as well as the best-fitting curves from the commonly used models. This new model is fully analytic and treats all starlight equally, in contrast to two-component dust attenuation models. We use the parameterization to investigate the relationship between the overall attenuation law shape and the strength of the 2175 Å bump. Our results indicate variation in star–dust geometry leads these features to correlate tightly, with grayer attenuation curves having weaker bumps.
Synchrotron Break Frequencies of Mildly to Highly Relativistic Outflows Observed Off-axis
Authors: Sadeh Gilad 
Published: December 2024

Abstract
We consider the synchrotron spectrum produced by mildly to highly relativistic collisionless shocks. Simple analytic formulae are derived for the break frequencies (peak frequency, self-absorption frequency, synchrotron, and inverse Compton cooling frequencies) of the emission produced by postshock plasma elements propagating at an angle θ

e
relative to the observer’s line of sight. These formulae reproduce well the results of earlier exact analytic calculations valid for ultrarelativistic shocks and also hold for γ < 10 and for “off-axis” propagation (deviating from the ultrarelativistic results by approximately 1 order of magnitude). Our results will improve parameter estimation accuracy from future observations of synchrotron emission produced by collisionless shocks driven by the relativistic ejected material from compact object mergers and jetted tidal disruption events. The improved accuracy for mildly relativistic velocities is essential since most events will be observed off-axis, with γ < 10 outflows dominating the synchrotron emission (due to relativistic beaming). For GW170817, our results imply that (i) the Lorentz factor of the plasma emitting the observed radiation is bounded by 2.6 < γ at t ∼ 10 days and by γ < 12 at t > 16 days, (ii) the interstellar medium (ISM) density, n, and the fraction of internal energy density held by magnetic fields, ε

B
, are bounded by n · ε

B
≲ 3 × 10−7 cm−3. In future merger events in higher-density ISM, the peak and cooling frequencies may be identified in the radio and X-ray bands; consequently, γ, n · ε

could be measured as opposed to the case of GW170817, where these frequencies are out of the observable range.
Des tigres grecs au tigre romain (IVe siècle av. J.-C.-IIe siècle apr. J.-C.)
Authors: Schneider Pierre 
Published: December 2024

Cet article revient sur l’image indifférenciée du tigre dans le monde gréco-romain qui domine dans les études consacrées à cet animal. Ce « tigre gréco-romain », ainsi que je le nomme, me semble être une construction artificielle. Le but de cette contribution est donc d’aborder la question de façon plus nuancée, par une approche diachronique, en distinguant documents grecs et documents romains. La première section décrit le tigre dans le monde grec (IVe-IIe siècle av. J.-C.). Dans la deuxième section, j’examine le tigre romain (Ier siècle av. J.-C. – IIe siècle apr. J.-C.). Dans la dernière section, j’essaie de dégager les principales raisons de cette divergence culturelle.

L’étude d’une mosaïque de la Maison du Faune (Pompéi, IIe siècle av. J.-C.) représentant un eros dionysiaque chevauchant un tigre à crinière richement harnaché permet de suivre une série iconographique d’époque hellénistique allant de Pella à Délos et Pompéi et de mesurer les adaptations locales du bestiaire dionysiaque, dont l’exotisme est réélaboré à mesure que les grands félins sont introduits en Italie par les triomphes et les jeux romains de la fin de la République.
Quand taire, c’est dire : L’envers et l’endroit de la revue culturelle Tropiques (1941‑1945)
Authors: Hel-Bongo Olga 
Published: December 2024

La revue Tropiques, que fondèrent Aimé et Suzanne Césaire, entourés d’amis tels que René Ménil et Gilbert Gratiant, célèbre dès le moment de sa parution, l’émergence d’un sujet littéraire antillais à part entière, malgré des conditions de production difficiles liées à la période de l’entre-deux-guerres. Pluridisciplinaire et savante, Tropiques adopte tous les tons pour parvenir à son but : « construire de nouveaux axes de pensée, libérer la parole et les consciences et poser, entre 1941 et 1945, des problèmes épistémologiques qui sont encore d’actualité » (Curtius 2017 : 416). Comment les initiateurs de ce projet culturel subversif purent-ils déjouer toute censure des représentants du gouvernement de Vichy, et éclairer les lecteurs auxquels la revue s’adressait ? Dans cet article, nous cherchons, à partir des conditions d’élaboration de la revue, à relever la prouesse verbale et littéraire des contributeurs dans leur mode de transmission de la culture (littéraire, historique, anthropologique, artistique et politique). Le mot d’ordre serait de feindre l’exotisme littéraire antillais dans un but noble et audacieux : celui de démanteler la « Raison » coloniale, perçue par les contributeurs comme une compromission scandaleuse des institutions religieuses, étatiques ou littéraires dans les pires crimes, méfaits et injustices de l’histoire de l’humanité.
