Autonomous Bearing Tone Tracking Algorithm
Authors: Sol Alon , Madar Eyal , Bortman Jacob , Klein Renata 
Published: July 2022

To date, much of the research done in the field of condition monitoring of rotating machinery is conducted in the frequency domain. The frequency domain analysis specifically for bearings is based on extracting features from the spectrum of the vibration signature. These features are mostly based on the amplitude at the bearing tones along with their sidebands and high order harmonics. Therefore, it is important to determine the location of the mentioned bearing tones in the spectrum accurately and automatically. For the case of ball bearings this process can be problematic due to slippage of the rolling elements and variations in the angle of contact. These may cause the bearing tone to deviate from its nominal value.
To this day, the common practice for bearing diagnostics is based on the vibration level at the analytical bearing tones or involvement of experts to identify the true location of the bearing tone. In this research an autonomous algorithm for bearing tone extraction, based on pattern matching, was developed. The proposed algorithm is based on the common assumption that the spectrum of a faulted bearing contains a certain known pattern of prominent peaks. The algorithm “scans” the entire spectrum and determines the frequency value which has the highest correlation to the mentioned pattern.
The proposed algorithm was validated and its capabilities are illustrated using experimental data. This algorithm is able to assist any diagnostic approach towards automatic and reliable feature extraction process, both for physics based and data driven approaches.

Published: July 2022

Статья посвящена исследованию вопросов обучения китайских студентов русскому языку (уровень В1). В ней предлагается использовать в учебном процессе актуальные новостные материалы, освещающие проблему современной действительности – пандемию COVID-19 и борьбу с новой коронавирусной инфекцией. Актуальность исследования обусловлена тем, что начиная с 2020 г. появилось большое количество лексических изменений в русском языке в связи с необходимостью обозначения реалий и явлений, вызванных пандемией. Китайские студенты, находящиеся вне русской языковой среды (уровень B1), испытывают трудности в выражении мыслей при общении с русскими собеседниками на тему борьбы с коронавирусом. Именно поэтому в данной статье обращается внимание на совершенствование коммуникативной компетенции в процессе обучения устной русской речи с использованием не только адаптированных, но и оригинальных, аутентичных текстов из новостных материалов о коронавирусе. Рекомендуются различные образовательные технологии обучения и система практических заданий для организации процесса обучения китайских студентов устной русской речи вне русской языковой среды с использованием новостных материалов о пандемии COVID-19.
The article is focused on the study of Russian language education towards Chinese students (level B1). It suggest that relevant news materials covering the urgent problem of modern reality – the problem of the COVID-19 pandemic and the fight against the new coronavirus infection (coronavirus) be used in the educational process. The relevance of the study is due to the fact that since 2020 there have been a large number of lexical changes in the Russian language due to new realities and phenomena caused by the pandemic. Chinese students who are outside the Russian language environment will find it difficult to communication with Russian people on the topic of fighting coronaviruses, if they are not familiar with the new words and fixed expressions in advance. That is why, in this article, it was chosen as a priority educational approach - using not only adapted version of original texts, but also from news materials about the coronavirus in the process of oral Russian education, to improve the ability of communication. Various educational teaching technologies and a series of practical tasks system are recommended for organizing the process of teaching Chinese students oral Russian outside the Russian language environment using news materials about the COVID-19 pandemic.

Optical Linear Polarization Study toward Czernik 3 Open Cluster at Different Spatial Scales
Authors: Uppal Namita , Ganesh Shashikiran , Bisht D. 
Published: July 2022

Abstract
We present the optical linear polarization observation of stars toward the core of the Czernik 3 cluster in the Sloan i band. The data were obtained using the EMPOL instrument on the 1.2 m telescope at Mount Abu Observatory. We study the dust distribution toward this cluster by combining the results from our polarization observations with the data from Gaia EDR3, WISE, and the H i, 12CO surveys. In addition, we use the polarimetric data of previously studied clusters within 15° of Czernik 3 to understand the large-scale dust distribution. The observational results of Czernik 3 show a large range in the degree of polarization, indicating that the dust is not uniformly distributed over the plane of the sky, even on a small scale. The distance to Czernik 3 is constrained to 3.6 ± 0.8 kpc using the member stars in the core region identified from Gaia EDR3 astrometry. This makes it one of the most distant clusters observed for optical polarization so far. The variation of observed degree of polarization and extinction toward this cluster direction suggests the presence of at least two dust layers along this line of sight at distances of ∼1 and ∼3.4 kpc. There is an indication of the presence of dust in the center of the cluster as seen from an increase in the degree of polarization and WISE W4 flux. The large-scale distribution of dust reveals the presence of a region of low dust content between the Local Arm and the Perseus arm.

Abstract
Although it is generally accepted that massive galaxies form in a two-phased fashion, beginning with a rapid mass buildup through intense starburst activities followed by primarily dry mergers that mainly deposit stellar mass at outskirts, the late time stellar mass growth of brightest cluster galaxies (BCGs), the most massive galaxies in the universe, is still not well understood. Several independent measurements have indicated a slower mass growth rate than predictions from theoretical models. We attempt to resolve the discrepancy by measuring the frequency of BCGs with multiple cores, which serve as a proxy of the merger rates in the central region and facilitate a more direct comparison with theoretical predictions. Using 79 BCGs at z = 0.06–0.15 with integral field spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) project, we obtain a multiple-core fraction of 0.11 ± 0.04 at z ≈ 0.1 within an 18 kpc radius from the center, which is comparable to the value of 0.08 ± 0.04 derived from mock observations of 218 simulated BCGs from the cosmological hydrodynamical simulation IllustrisTNG. We find that most cores that appear close to the BCGs from imaging data turn out to be physically associated systems. Anchoring on the similarity in the multiple-core frequency between the MaNGA and IllustrisTNG, we discuss the mass growth rate of BCGs over the past 4.5 Gyr.
What It Takes to Measure Reionization with Fast Radio Bursts
Authors: Heimersheim Stefan , Sartorio Nina S. , Fialkov Anastasia , Lorimer Duncan R. 
Published: July 2022

Abstract
Fast Radio Bursts (FRBs) are extragalactic radio transients that exhibit a distance-dependent dispersion of their signal, and thus can be used as cosmological probes. In this article we, for the first time, apply a model-independent approach to measure reionization from synthetic FRB data assuming these signals are detected beyond redshift 5. This method allows us to constrain the full shape of the reionization history as well as the CMB optical depth τ while avoiding the problems of commonly used model-based techniques. A total of 100 localized FRBs, originating from redshifts 5–15, could constrain (at 68% confidence level) the CMB optical depth to within 11%, and the midpoint of reionization to 4%, surpassing current state-of-the-art CMB bounds and quasar limits. Owing to the higher numbers of expected FRBs at lower redshifts, the τ constraints are asymmetric (+14%, −7%), providing a much stronger lower limit. Finally, we show that the independent constraints on reionization from FRBs will improve limits on other cosmological parameters, such as the amplitude of the power spectrum of primordial fluctuations.

Abstract
While β Pic is known to host silicates in ring-like structures, whether the properties of these silicate dust vary with stellocentric distance remains an open question. We re-analyze the β Pictoris debris disk spectrum from the Spitzer Infrared Spectrograph (IRS) and a new Infrared Telescope Facility Spectrograph and Imager spectrum to investigate trends in Fe/Mg ratio, shape, and crystallinity in grains as a function of wavelength, a proxy for stellocentric distance. By analyzing a re-calibrated and re-extracted spectrum, we identify a new 18 μm forsterite emission feature and recover a 23 μm forsterite emission feature with a substantially larger line-to-continuum ratio than previously reported. We find that these prominent spectral features are primarily produced by small submicron-sized grains, which are continuously generated and replenished from planetesimal collisions in the disk and can elucidate their parent bodies’ composition. We discover three trends about these small grains: as stellocentric distance increases, (1) small silicate grains become more crystalline (less amorphous), (2) they become more irregular in shape, and (3) for crystalline silicate grains, the Fe/Mg ratio decreases. Applying these trends to β Pic’s planetary architecture, we find that the dust population exterior to the orbits of β Pic b and c differs substantially in crystallinity and shape. We also find a tentative 3–5 μm dust excess due to spatially unresolved hot dust emission close to the star. From our findings, we infer that the surfaces of large planetesimals are more Fe-rich and collisionally processed closer to the star but more Fe-poor and primordial farther from the star.
Thomson Scattering above Solar Active Regions and an Ad Hoc Polarization Correction Method for the Emissive Corona

Published: July 2022

Abstract
Thomson-scattered photospheric light is the dominant constituent of the lower solar corona’s spectral continuum viewed off-limb at optical wavelengths. Known as the K-corona, it is also linearly polarized. We investigate the possibility of using the a priori polarized characteristics of the K-corona, together with polarized emission lines, to measure and correct instrument-induced polarized crosstalk. First we derive the Stokes parameters of the Thomson scattering of unpolarized light in an irreducible spherical tensor formalism. This allows forward synthesis of the Thomson-scattered signal for the more complex scenario that includes symmetry-breaking features in the incident radiation field, which could limit the accuracy of our proposed technique. For this, we make use of an advanced 3D radiative magnetohydrodynamic coronal model. Together with synthesized polarized signals in the Fe xiii 10746 Å emission line, we find that an ad hoc correction of telescope- and instrument-induced polarization crosstalk is possible under the assumption of a nondepolarizing optical system.
Evidence for Parametric Decay Instability in the Lower Solar Atmosphere
Authors: Hahn Michael , Fu Xiangrong , Savin Daniel Wolf 
Published: July 2022

Abstract
We find evidence for the first observation of the parametric decay instability (PDI) in the lower solar atmosphere. In particular, we find that the power spectrum of density fluctuations near the solar transition region resembles the power spectrum of the velocity fluctuations but with the frequency axis scaled up by about a factor of 2. These results are from an analysis of the Si iv lines observed by the Interface Region Imaging Spectrometer in the transition region of a polar coronal hole. We also find that the density fluctuations have radial velocity of about 75 km s−1 and that the velocity fluctuations are much faster with an estimated speed of 250 km s−1, as is expected for sound waves and Alfvén waves, respectively, in the transition region. Theoretical calculations show that this frequency relationship is consistent with those expected from PDI for the plasma conditions of the observed region. These measurements suggest an interaction between sound waves and Alfvén waves in the transition region, which is evidence for the parametric decay instability.

Distinctions légales ou discriminations ?

Published: July 2022

S’appuyant sur deux enquêtes menées en France entre 2011 et 2020, cet article montre que les parents homo/bisexuels sont confrontés à plusieurs dimensions de l’hétéronormativité lorsqu’ils interagissent avec les services publics. Leur traitement différentiel par les agents des services publics peut venir d’une distinction légale ou d’une discrimination dans la prise en charge. Ces personnes homo/bisexuelles deviennent parents en marge des services publics français médicaux et de l’adoption qui consacrent l’hétérosexualité reproductive. Elles font face à la présomption d’hétérosexualité qui transforme les premiers contacts avec les services publics de l’enfance en coming-out . Elles négocient des arrangements au quotidien avec la CAF, la crèche, l’école, etc. Les interprétations et réactions des parents varient en fonction de leur trajectoire sexuelle et sociale, leurs ressources socio-économiques, leur statut juridique et des marges de manœuvre offertes par chaque service public.
QPlayer: Lightweight, scalable, and fast quantum simulator
Authors: Jin Ki‐Sung , Cha Gyu‐Il 
Published: July 2022

AbstractWith the rapid evolution of quantum computing, digital quantum simulations are essential for quantum algorithm verification, quantum error analysis, and new quantum applications. However, the exponential increase in memory overhead and operation time is challenging issues that have not been solved for years. We propose a novel approach that provides more qubits and faster quantum operations with smaller memory than before. Our method selectively tracks realized quantum states using a reduced quantum state representation scheme instead of loading the entire quantum states into memory. This method dramatically reduces memory space ensuring fast quantum computations without compromising the global quantum states. Furthermore, our empirical evaluation reveals that our proposed idea outperforms traditional methods for various algorithms. We verified that the Grover algorithm supports up to 55 qubits and the surface code algorithm supports up to 85 qubits in 512 GB memory on a single computational node, which is against the previous studies that support only between 35 qubits and 49 qubits.
