Effect of SrO and ZnO on Densification and in Vitro Behaviors of P<sub>2</sub>O<sub>5</sub>-CaO-Na<sub>2</sub>O-SiO<sub>2</sub>-TiO<sub>2</sub> Bioactive Glass-Ceramics
Authors: Razavi Seyedsahameddin , Yekta Bijan Eftekhari , Khavandi Alireza 
Published: February 2022

Phosphate based-glass ceramics in the system of P2O5-CaO-Na2O-SiO2-TiO2 were obtained by the sintering method. For evaluating the effect of strontium and zinc, different amounts of these elements were doped in the parent glass instead of calcium oxide. Sintering behavior of the glasses was evaluated through the measurement of bulk density, liquid absorption, and open porosity percentages. Based on the results, 600 °C was determined as the optimum sintering temperature. Based on the X-Ray diffractometry, calcium pyrophosphate was precipitated during the sintering process as the main crystallized phase. It is worth noting that changing the parent glass composition led to its phase transformation. Variation in the pH and ion concentration in the simulated body fluid as well as weight loss percentages of the samples were considered to evaluate the dissolution behavior of the samples. The in vitro tests showed that increasing the amount of strontium and zinc intensified the dissolution rate. According to scanning electron micrographs, hydroxyapatite nuclei precipitated on the surfaces of the samples after three days of simulated body fluid (SBF) soaking; but, they were dissolved in the solution after 28 days due to the dissolution of the substrate. Some residues of the grown apatite-like layer were observed on the surface of the composition when 25 and 2.5 molar percent of calcium were substituted for strontium and zinc, respectively.

Abstract
We present a case study of the stellar clumps in G04-1—a clumpy, turbulent disk galaxy located at z = 0.13—from the DYnamics of Newly-Assembled Massive Objects sample, using adaptive optics-enabled K-band imaging (∼2.25 kpc arcsec−1) with Keck-NIRC2. We identify 15 stellar clumps in G04-1 with a range of masses from 3.6 × 106–2.7 × 108

Using Hubble Space Telescope observations from the Wide Field Camera on the Advanced Camera for Surveys, with the F336W and F467M filters, we also find evidence of radial trends in the stellar properties of the clumps: the clumps closer to the center of G04-1 are more massive (consistent with observations in high-z systems) and appear more red, suggesting they may be more evolved. Using our high-resolution data, we construct a star-forming main sequence for G04-1 in terms of spatially resolved quantities, and find that all regions (both clump and intraclump) within the galaxy are experiencing an enhanced mode of star formation routinely observed in galaxies at high-z. In comparison to recent simulations, our observations of a number of clumps with masses of 107–108

The Fast Radio Burst-emitting Magnetar SGR 1935+2154—Proper Motion and Variability from Long-term Hubble Space Telescope Monitoring

Published: February 2022

Abstract
We present deep Hubble Space Telescope (HST) near-infrared (NIR) observations of the magnetar SGR 1935+2154 from 2021 June, approximately 6 yr after the first HST observations, a year after the discovery of fast-radio-burst-like emission from the source, and in a period of exceptional high-frequency activity. Although not directly taken during a bursting period the counterpart is a factor of ∼1.5–2.5 brighter than seen at previous epochs with F140W(AB) = 24.65 ± 0.02 mag. We do not detect significant variations of the NIR counterpart within the course of any one orbit (i.e., on minutes to hour timescales), and contemporaneous X-ray observations show SGR 1935+2154 to be at the quiescent level. With a time baseline of 6 yr from the first identification of the counterpart we place stringent limits on the proper motion (PM) of the source, with a measured PM of μ = 3.1 ± 1.5 mas yr−1. The direction of PM indicates an origin of SGR 1935+2154 very close to the geometric center of SNR G57.2+08, further strengthening their association. At an adopted distance of 6.6 ± 0.7 kpc, the corresponding tangential space velocity is ν

T
= 97 ± 48 km s−1 (corrected for differential Galactic rotation and peculiar solar motion), although its formal statistical determination may be compromised owing to few epochs of observation. The current velocity estimate places it at the low end of the kick distribution for pulsars, and makes it among the lowest known magnetar kicks. When collating the few-magnetar kick constraints available, we find full consistency between the magnetar kick distribution and the much larger pulsar kick sample.
Consistency of von Karman Decay Rate with the Energy Supply Rate and Heating Rate Observed by Parker Solar Probe

Published: February 2022

Abstract
The von Kármán-Howarth equations give a starting basis for the classical turbulence theory. The formula for the magnetohydrodynamics von Kármán decay rate represents an energy source in many solar wind models with turbulence as the driver. However, it still lacks the radial trend comparison between the von Kármán decay rate, the energy supply rate, and the perpendicular heating rate based on direct observations of the solar wind. Here we carry out this kind of comparison for the first time using Parker Solar Probe measurements from its first three orbits. We find that the radial variation of the von Kármán decay rate is consistent with that of both the energy supply rate and the heating rate in the slow solar wind. These results support the idea that the von Kármán decay law is an active process responsible for solar wind heating. These results also suggest a new idea that both the von Kármán decay law and the low-frequency break sweeping may be controlled by the same nonlinear process. Some limitations of the present study are also addressed.
Turbulence-dominated Shock Waves: 2D Hybrid Kinetic Simulations
Authors: Nakanotani M. , Zank G. P. , Zhao L.-L. 
Published: February 2022

Abstract
We investigate the interaction of turbulence with shock waves by performing 2D hybrid kinetic simulations. We inject force-free magnetic fields upstream that are unstable to the tearing-mode instability. The magnetic fields evolve into turbulence and interact with a shock wave whose sonic Mach number is 2.4. Turbulence properties, the total and normalized residual energy and the normalized cross helicity, change across the shock wave. While the energy of velocity and magnetic fluctuations is mostly distributed equally upstream, the velocity fluctuations are amplified dominantly downstream of the shock wave. The amplitude of turbulence spectra for magnetic, velocity, and density fluctuations are also increased at the shock wave while their spectral index remains unchanged. We compare our results with the Zank et al. model of turbulence transmission across a shock, and find that it provides a reasonable explanation for the spectral change across the shock wave. We find that particles are efficiently accelerated at the shock front, and a power-law spectrum forms downstream. This can be explained by diffusive shock acceleration, in which particles gain energy by being scattered upstream and downstream of a shock wave. The trajectory of an accelerated particle suggests that upstream turbulence plays a role scattering of particles.

Abstract
Hot subdwarf stars are a particular type of star that is crucial for studying binary evolution and atmospheric diffusion processes. In recent years, identifying hot subdwarfs by machine-learning methods has become a hot topic, but there are still limitations in automation and accuracy. In this paper, we proposed a robust identification method based on a convolutional neural network. We first constructed the data set using the spectral data of LAMOST DR7-V1. We then constructed a hybrid recognition model including an eight-class classification model and a binary classification model. The model achieved an accuracy of 96.17% on the testing set. To further validate the accuracy of the model, we selected 835 hot subdwarfs that were not involved in the training process from the identified LAMOST catalog (2428, including repeated observations) as the validation set. An accuracy of 96.05% was achieved. On this basis, we used the model to filter and classify all 10,640,255 spectra of LAMOST DR7-V1, and obtained a catalog of 2393 hot subdwarf candidates, of which 2067 have been confirmed. We found 25 new hot subdwarfs among the remaining candidates by manual validation. The overall accuracy of the model is 87.42%. Overall, the model presented in this study can effectively identify specific spectra with robust results and high accuracy, and can be further applied to the classification of large-scale spectra and the search for specific targets.
Slavko Ježić entre Vienne et Paris. Un marquis Croate qui traduisait de l’italien et du français. Un George Dandin qui parle slovène
Authors: Smolej Tone 
Published: February 2022

En 1916, Slavko Ježić (1895-1969) a achevé son cursus d’études romanes et slaves à l’Université de Vienne en soutenant un thèse de doctorat consacrée à la création littéraire du marquis croate F. Kr. Frankopan (1643-1671), plus connu pour avoir participé à un complot contre les Habsbourgs. En s’intéressant au legs du marquis, Ježić a surtout étudié les retranscriptions des conférences dispensées aux académies italiennes de la cour de Vienne ainsi que la traduction d’un fragment du George Dandin de Molière où le célèbre cocu s’exprime en slovène. En 1921, ayant obtenu une bourse pour étudier à Paris, Ježić a publié un court résumé de sa thèse dans la Revue de littérature comparée .
Premières « Influences orientales » dans la Revue de littérature comparée (1921-1925)
Authors: Daniel Yvan 
Published: February 2022

La question des « influences orientales » dans les littératures européennes apparaît dès 1921 dans la Revue de Littérature Comparée , d’abord indirectement à travers les ouvrages signalés dans les bibliographies qui accompagnent chaque numéro. L’« Orient » désigne alors des aires culturelles et linguistiques très larges, du Proche-Orient biblique et musulman jusqu’à l’Asie orientale, en passant par l’Inde. Cet article examine, sur les cinq premières années de la Revue , les premières publications d’études comparatistes sur ce sujet, et s’interroge, plus généralement, sur les débats qui portent à cette période sur les causes et les conséquences de ces échanges de plus en plus fréquents entre l’Europe et le monde oriental et asiatique.

This study aims to investigate the use of Rocket seed (Eruca Sativa Mill) gum (RSG) as a novel fat replacer in the formulation of low-fat emulsion. For this purpose, formulation of the salad dressing was optimized by using response surface methodology (RSM) based on the rheological properties measured by steady shear (K), dynamic rheological analysis (K', K''), and three interval time test (Deformation (%) and Recovery (%)). All samples showed shear-thinning character and viscoelastic solid character. Herschel Buckley model parameters, namely, t0, K, and n values, were changed between 0.36 and 12.58 Pa, 1.67, and 27. 12 Pa.sn, 0.15 and 0.27 respectively. In all samples, the G' value was higher than G'' in all frequency range. The samples containing high RSG showed a lower percentage of deformation (Def %) and higher recovery (Rec %) values. Optimization was performed based on the rheological properties of the control samples, and the optimum formulation of low salad dressing was 3.73 % RSG, 10 % oil, and 1 % EYP. Low-fat salad dressing samples stabilized by RSG and control samples showed similar characteristics in terms of particle size, PDI, zeta potential, and emulsion stability index values. This study suggested that RSG could be used as a natural fat replacer in low-fat salad dressing type emulsions.

Authors: Santos Júnior Luís Carlos Oliveira dos , Schulz Matthias , Knorr Dietrich , Amante Edna Regina 
Published: February 2022

In this study experiments were performed using a batch pulsed electric field (PEF) system at different electric field strengths with a voltage of 35 kV and pulse frequency of 3 Hz, at 20 and 40°C, with pulse width between 0.8 and 1.0 µs, to evaluate the inactivation of Escherichia coli in pumpkin juice and nectar. The performance of the PEF technology can vary as a function of several process parameters and the conditions and procedures applied. The physicochemical characteristics (pH, total soluble solids, electrical conductivity) of the pumpkin juice were also evaluated. The juice showed 5.01 ± 0.01 of pH, 10.70 ± 0.11 (mS cm-1) of electric conductivity and 9.85 ± 0.07 of soluble solids while in nectar, these parameters were changed to 5.11 ± 0.01 of pH, 8.54 ± 0.21 of electric conductivity and 6.40 ± 0.12 of soluble solids. The use of a temperature of 40°C and pumpkin nectar (70:30, juice: distilled water) showed no difference in the bacterial reduction compared to 20°C and using 100% pumpkin juice, since in non-thermal processes it is better to use lower temperatures for less energy expenditure and less possibility of changes in raw material. The data showed that the PEF treatment reduced the microbial load moderately in all experiments, by a maximum of approximately 2.5 - 3 log cycles with 80 J g-1 of specific energy and above 26,000 V cm-1 of field strength
A cross-sectional study on the use of near-visual display devices in the Middle-Eastern children population
Authors: Maher Thuraya N. , Khan M. Irfan , Azzam Noor 
Published: February 2022

PURPOSE:
The objective of the study is to highlight the demographics, awareness of hazards, ocular symptoms, and healthy practices associated with the use of near-visual display devices (NVDD) in the Middle-Eastern children population.

METHODS:
Two hundred and sixty participants aged 4–16 years responded to a questionnaire on demographic aspects, symptoms, awareness of hazards, and healthy practices associated with the use of NVDD.

RESULTS:
Daily use, prolonged viewing (for 3 h or more), and the use of multiple NVDD (2 or more) were seen in the majority (79.6%, 90%, and 71.5%, respectively). Smartphones, tablets, and iPads were the most used devices. Symptoms were present in 92.3%. The association between appearance of symptoms and duration of exposure to the digital screen was statistically significant (P < 0.00001). Symptoms were itching (40.0%), watery eyes (31.0%), burning sensation (24.0%), headache (22.0%), excessive blinking (20.0%), dry eyes (20.0%), foreign body sensation (10.0%), redness (10.0%), eye or periorbital pain (8.0%), blurry vision (5.0%), and photophobia (3.0%). A low minority (9.2%) were aware of the harmful effects of prolonged use of NVDD and the protective measures against it; schools were not involved in educating students about the proper use of these devices. Sixty percent attended periodic eye checkup, 20.0% set time limit, 6.9% properly adjusted screen brightness, and 15.0% practiced outdoor play daily.

CONCLUSION:
Majority of the children (90%) were symptomatic when used NVDD excessively. Children are generally uneducated about healthy practices to prevent these symptoms. Spreading awareness among children and parents is important.
