Φίλοι καὶ Σύμμαχοι : les relations entre les Attalides et les Étoliens au IIIe et au IIe siècle avant J.-C
Authors: Gondat Julien 
Published: October 2022

L’analyse précise des témoignages que nous possédons permet de proposer une nouvelle lecture des motivations qui ont poussé les Attalides de Pergame et la Confédération étolienne à se rapprocher ou à s’éloigner au IIIe et au
IIe siècle av. J.-C. On constatera notamment que la genèse de ces relations était avant tout liée à la volonté des Attalides de légitimer leur nouveau pouvoir, plutôt qu’à des visées offensives communes contre la Macédoine. À l’inverse de ce que l’on a pu croire, c’est justement l’absence de solidarité réciproque dans les conflits militaires contre Philippe V qui a le plus contribué à séparer les deux alliés, au point d’agir dans des camps opposés pendant la guerre antiochique. L’amitié étolo-pergaménienne fut toutefois réactivée quelques temps après le règlement d’Apamée, sans doute vers 185, à l’occasion d’un bienfait d’Eumène II dont témoigne l’érection du pilier étolien à Delphes, que nous datons de cette époque. Ceci n’empêcha pas les Étoliens, pourtant, d’être séduits par la propagande du nouveau roi de Macédoine, Persée, en remettant une nouvelle fois en cause l’alliance avec Pergame.

Classroom Experiments Testing Constancy of Speed of Photons
Authors: peng hui 
Published: October 2022

<p>Special Relativity (SR) is the cornerstone for modern physics and variety of applications. SR is based on two postulates, the principle of relativity (the first postulate) and the principle of constancy of speed of light (the second postulate). Recently we have (1) shown that the light propagate as particles/photons in the “pure” wave experiments, such as double slit and grating experiments; (2) proposed experiments to measure the speed of the photons by an observer moving relative to the source and thus, to test the second postulate for photons. In this article we propose a classroom experiment to test the second postulate. If the experiments show the existence of interference pattern (the negative result), the constancy of the speed of the photons holds, namely the second postulate of SR is experimentally confirmed. If the experiments show no interference pattern (positive result), then the propagation speed of photons is not constant, namely, the second postulate of SR is disproved. Either negative result or positive results would be profoundly significant. </p>

Published: October 2022

Introduction: Benign prostate hyperplasia is a proliferation of stromal cells and epithelial cells which results an enlargement of the prostate gland and can cause obstruction of the urinary tract. Adenocarcinoma prostate is an invasive carcinoma consisting of a neoplasm of prostate epithelial cells with secretory cell differentiation. Abnormal growth of the prostate gland like benign lesions and malignant lesions are generally affected by androgen receptor (AR). The aim of this research is to analyse the comparison of AR expression in benign prostate hyperplasia and adenocarcinoma prostate.
Methods: The design of this research is analiytical study with cross sectional approach. The samples are 18 cases of benign prostate hyperplasia and 20 cases of adenocarcinoma prostate. The samples are observed only once and at a time.
Results: The average age of the adenocarcinoma prostate case was 63.95 ± 12.03 years (age range 33-84 years) while in the benign prostate hyperplasia case, the average age was 66.78 ± 9.49 (age range 54–89 years). There are no different about the expression of AR in benign prostate hyperplasia and adenocarcinoma prostate used Allred scores. There was a weak and negative correlation between Gleason score and AR expression in the adenocarcinoma prostate case group (p=0.237).
Conclusion: There are no differences related to the expression of AR between the case of adenocarcinoma prostate and benign prostatic hyperplasia.

Increasing the reliability and availability of the electric motor using combined static and dynamic diagnostics
Authors: Nikolić Saša , Ćalasan Radoš 
Published: October 2022

The aim of this paper is to point out the importance of early diagnostics and assessment of the condition of the electric motor in increasing the reliability and availability of the plant. Electric motors are unavoidable elements in every production process. As the complexity of the process increases, the number of electric motors involved in it increases. By increasing the number of electric motors, the possibility of cancelling and interrupting production increases. It is therefore very important to monitor the situation and detect defects at an early stage so that timely repair or replacement can be planned, without affecting the production process. Modern diagnostic methods that can be used both during the operation of the electric motor, and with the dismounted and dismantled electric motor are presented in the paper. With good organization and testing schedule and a combination of static and dynamic diagnostic methods, the reliability and availability of the plant can be significantly increased. With increased reliability and availability, a reduction in maintenance costs is achieved. In this article, some examples from the author's practice are given, when serious engine defects were discovered. These cases confirm the value of predictive testing to increase reliability of electric motor.

Abstract
We started a survey with CHARA/MIRC-X and VLTI/GRAVITY to search for low-mass companions orbiting individual components of intermediate-mass binary systems. With the incredible precision of these instruments, we can detect astrometric “wobbles” from companions down to a few tens of microarcseconds. This allows us to detect any previously unseen triple systems in our list of binaries. We present the orbits of 12 companions around early F- to B-type binaries, 9 of which are new detections and 3 of which are first astrometric detections of known radial velocity (RV) companions. The masses of these newly detected components range from 0.45 to 1.3 M
⊙. Our orbits constrain these systems to a high astrometric precision, with median residuals to the orbital fit of 20–50 μas in most cases. For seven of these systems we include newly obtained RV data, which help us to identify the system configuration and to solve for masses of individual components in some cases. Although additional RV measurements are needed to break degeneracy in the mutual inclination, we find that the majority of these inner triples are not well aligned with the wide binary orbit. This hints that higher-mass triples are more misaligned compared to solar and lower-mass triples, though a thorough study of survey biases is needed. We show that the ARMADA survey is extremely successful at uncovering previously unseen companions in binaries. This method will be used in upcoming papers to constrain companion demographics in intermediate-mass binary systems down to the planetary-mass regime.
Differential Behaviors of Suprathermal 4He and Fe Populations in the Interplanetary Medium during Solar Cycle 24
Authors: Dalal Bijoy , Chakrabarty D. , Srivastava N. 
Published: October 2022

Abstract
Investigations on the solar cycle variation of the properties of suprathermal populations (H and other heavy ions like 4He, 3He, C, O, and Fe) in the solar wind are sparse and hence poorly understood. In the present investigation, solar cycle variations of “quiet” time suprathermal elements are investigated using <∼ 1 MeV n−1 particle flux data obtained from the Ultra-Low Energy Isotope Spectrometer on board the Advanced Composition Explorer satellite during solar cycles 23 and 24. The analysis reveals that helium (4He) shows zero or positive lags with respect to sunspot numbers in solar cycle 23 while it shows zero or negative lag in solar cycle 24. On the contrary, although iron (Fe) shows a zero or positive lag in cycle 23 similar to 4He, it shows only a zero lag in cycle 24 and no negative lag is seen. Further, significant differences in the spectral indices are seen between 4He and Fe in cycle 24 compared to cycle 23. These results suggest that generation mechanisms responsible for suprathermal 4He and Fe underwent changes in cycle 24 and these mechanisms are probably dependent on the first ionization potential and mass-to-charge ratio. This proposition gets credence from the fact that changes in the lags and spectral slopes for C and O are not significantly different in cycles 23 and 24.
An Argument in Favor of Magnetic Polarity Reversals Due to Heat Flux Variations in Fully Convective Stars and Planets
Authors: Nigro Giuseppina 
Published: October 2022

Abstract
Low-mass M dwarf stars, T Tauri stars, as well as planets such as the Earth and Jupiter are permeated by large-scale magnetic fields generated by the convection-driven dynamo operating in their convection zones. These magnetic fields are often characterized by a significant time variability, most prominently expressed by the inversions of their polarity, denoted as reversals, whose mechanism has not been completely understood. This work aims to gain some insights into the mechanism that generates these reversals. With this purpose, a simplified nonlinear model is developed to investigate the role played in polarity reversals by the convective heat transfer occurring in stellar and planetary convection zones. A model result is the enhancement of the global heat transport before polarity reversals, showing the crucial role that heat transport might play in their occurrence. This role is elucidated by considering that a reversal has a greater than 70% probability of occurring during a burst of convective heat transport. This high probability has been found in 94 out of 101 numerical simulations obtained by changing characteristic model parameters. Moreover, the causal relationship between the convective heat flux growth and the magnetic field variations is highlighted by the temporal antecedence of the former relative to the latter and by convergent cross mapping, namely a statistical test for detecting causality. It would thus be expected that higher levels of temporal variability in the planetary and stellar magnetic fields may be correlated to a higher heat transfer efficiency achieved in the interior of these celestial bodies.
Predicting the Stability of Hierarchical Triple Systems with Convolutional Neural Networks
Authors: Lalande Florian , Trani Alessandro Alberto 
Published: October 2022

Abstract
The dynamical stability of hierarchical triple systems is a long-standing question in celestial mechanics and dynamical astronomy. Assessing the long-term stability of triples is challenging because it requires computationally expensive simulations. Here we propose a convolutional neural network model to predict the stability of equal-mass hierarchical triples by looking at their evolution during the first 5 × 105 inner binary orbits. We employ the regularized few-body code tsunami to simulate 5 × 106 hierarchical triples, from which we generate a large training and test data set. We develop 12 different network configurations that use different combinations of the triples’ orbital elements and compare their performances. Our best model uses six time series, namely, the semimajor axes ratio, the inner and outer eccentricities, the mutual inclination, and the arguments of pericenter. This model achieves excellent performance, with an area under the ROC curve score of over 95% and informs of the relevant parameters to study triple systems stability. All trained models are made publicly available, which allows predicting the stability of hierarchical triple systems 200 times faster than pure N-body methods.
Characterizing Extreme Emission Line Galaxies. II. A Self-consistent Model of Their Ionizing Spectrum*

Published: October 2022

Abstract
Observations of high-redshift galaxies (z > 5) have shown that these galaxies have extreme emission lines with equivalent widths much larger than their local star-forming counterparts. Extreme emission line galaxies (EELGs) in the nearby universe are likely analogs to galaxies during the Epoch of Reionization and provide nearby laboratories to understand the physical processes important to the early universe. We use Hubble Space Telescope/Cosmic Origins Spectrograph and Large Binocular Telescope/Multi-Object Double Spectrographs spectra to study two nearby EELGs, J104457 and J141851. The far-UV spectra indicate that these two galaxies contain stellar populations with ages ≲10 Myr and metallicities ≤0.15 Z
⊙. We use photoionization modeling to compare emission lines from models of single-age bursts of star formation to observed emission lines and find that the single-age bursts do not reproduce high-ionization lines including [O iii] or very-high-ionization lines like He ii or O iv]. Photoionization modeling using the stellar populations fit from the UV continuum similarly is not capable of reproducing the very-high-energy emission lines. We add a blackbody to the stellar populations fit from the UV continuum to model the necessary high-energy photons to reproduce the very-high-ionization lines of He ii and O iv]. We find that we need a blackbody of 80,000 K and ∼45%–55% of the luminosity from the blackbody and young stellar population to reproduce the very-high-ionization lines while simultaneously reproducing the low-, intermediate-, and high-ionization emission lines. Our self-consistent model of the ionizing spectra of two nearby EELGs indicates the presence of a previously unaccounted-for source of hard ionizing photons in reionization analogs.
Coronal Mass Ejection Deformation at 0.1 au Observed by WISPR

Published: October 2022

Abstract
Although coronal mass ejections (CMEs) resembling flux ropes generally expand self-similarly, deformations along their fronts have been reported in observations and simulations. We present evidence of one CME becoming deformed after a period of self-similar expansion in the corona. The event was observed by multiple white-light imagers on 2021 January 20–22. The change in shape is evident in observations from the heliospheric imagers from the Wide-Field Imager for Solar Probe Plus (WISPR), which observed this CME for ∼44 hr. We reconstruct the CME using forward-fitting models. In the first hours, observations are consistent with a self-similar expansion, but later on the front flattens, forming a dimple. Our interpretation is that the CME becomes deformed at ∼0.1 au owing to differences in the background solar wind speeds. The CME expands more at higher latitudes, where the background solar wind is faster. We consider other possible causes for deformations, such as loss of coherence and slow-mode shocks. The CME deformation seems to cause a time-of-arrival error of 16 hr at ∼0.5 au. The deformation is clear only in the WISPR observations; thus, it would have been missed by 1 au coronagraphs. Such deformations may help explain the time-of-arrival errors in events where only coronagraph observations are available.
