A Systematic Analysis of Stellar Populations in the Host Galaxies of Changing-look AGNs
Authors: Jin Jun-Jie , Wu Xue-Bing , Feng Xiao-Tong
Published: March 2022

“Changing-look” active galactic nuclei (CL-AGNs) are a newly discovered class of AGNs that show the appearance (or disappearance) of broad emission lines within short timescales (months to years), and are often associated with dramatic changes in their continuum emissions. They provide us with an unprecedented chance to directly investigate the host galaxy properties with minimal contamination from the luminous central engine during the turn-off state, which is difficult for normal luminous AGNs. In this work, for the first time, we systematically characterize the stellar populations and star formation histories of host galaxies for 26 turn-off CL-AGNs using the stellar population synthesis code STARLIGHT. We find that the stellar populations of CL-AGNs are similar to those of normal AGNs, except that the intermediate stellar populations contribute more fractions. We estimate their stellar velocity dispersions (σ
⋆) and black hole masses (M
BH,vir), and find that CL-AGNs also follow the overall M
BH–σ
⋆ relationship. We also confirm the previous claims that CL-AGNs tend to be biased toward lower Eddington ratios, and that their extreme variabilities are more likely due to the intrinsic changes of the accretion rates. In addition, CL-AGNs with recent star formations tend to have higher Eddington ratios. Compared with previous studies, our analysis suggests that there may be a correlation between CL-AGN host galaxy properties and their CL phenomena.

Published: March 2022

We explore the effects of anisotropic thermal conduction, anisotropic pressure, and magnetic field strength on the hot accretion flows around black holes by solving the axisymmetric, steady-state magnetohydrodynamic equations. The anisotropic pressure is known as a mechanism for transporting angular momentum in weakly collisional plasmas in hot accretion flows with extremely low mass accretion rates. However, anisotropic pressure does not extensively impact the transport of the angular momentum, it leads to shrinkage of the wind region. Our results show that the strength of the magnetic field can help the Poynting energy flux overcome the kinetic energy flux. This result may be applicable to the understanding of the hot accretion flow in the Galactic Center Sgr A* and the M87 galaxy.

A photometric and spectroscopic investigation is performed on five W Ursae Majoris eclipsing binaries J015818.6+260247 (hereinafter as J0158b), J073248.4+405538 (hereinafter as J0732), J101330.8+494846 (hereinafter as J1013), J132439.8+130747 (hereinafter as J1324), and J152450.7+245943 (hereinafter as J1524). The photometric data are collected with the help of the 1.3 m Devasthal Fast Optical Telescope, the 1.04 m Sampurnanand Telescope, and the Transiting Exoplanet Survey Satellite space mission. The low-resolution spectra of the 4 m Large Sky Area Multi-Object Fiber Spectroscopic Telescope are used for spectroscopic analysis. The orbital period change of these systems is determined using our photometric data and previously available photometric data from different surveys. The orbital period of J1013 and J1524 is changing at a rate of −2.552 (±0.249) × 10−7 days yr−1 and −6.792( ±0.952) × 10−8 days yr−1, respectively, while others do not show any orbital period change. The orbital period change of J1013 and J1524 corresponds to a mass transfer rate of 2.199 × 10−7
and 6.151 × 10−8
M
⊙ yr−1 from the primary to the secondary component in these systems. It is likely that angular momentum loss via magnetic braking may also be responsible for the observed orbital period change in the case of J1524. All systems have a mass ratio lower than 0.5, except J0158b with a mass ratio of 0.71. All the systems are shallow-type contact binaries. J0158b and J1524 are subtype A while others are subtype W. The H
α
emission line region is compared with template spectra prepared using two inactive stars with the help of the STARMOD program. The J0158, J1324, and J1524 systems show excess emission in the residual spectra after subtraction of the template.

Symmetric achromatic variability (SAV) is a rare form of radio variability in blazars that has been attributed to gravitational milli-lensing by a ∼102–105
M
⊙ mass condensate. Four SAVs have been identified between 1980 and 2020 in the long-term radio monitoring data of the blazar PKS 1413 + 135. We show that all four can be fitted with the same, unchanging, gravitational lens model. If SAV is due to gravitational milli-lensing, PKS 1413 + 135 provides a unique system for studying active galactic nuclei with unprecedented microarcsecond resolution, as well as for studying the nature of the milli-lens itself. We discuss two possible candidates for the putative milli-lens: a giant molecular cloud hosted in the intervening edge-on spiral galaxy, and an undetected dwarf galaxy with a massive black hole. We find a significant dependence of SAV crossing time on frequency, which could indicate a fast shock moving in a slower underlying flow. We also find tentative evidence for a 989 day periodicity in the SAVs, which, if real, makes possible the prediction of future SAVs: the next three windows for possible SAVs begin in 2022 August, 2025 May, and 2028 February.

s
, and [3.6] and [4.5] micron absolute magnitudes for 37 nearby Milky Way Cepheids, covering the period range between 5 and 60 days. We apply these period–luminosity relations to Cepheids in the Large and Small Magellanic Clouds and find that the derived distances are significantly discrepant with the geometric distances according to detached eclipsing binaries (DEBs). We explore several potential causes of these issues, including reddening, metallicity, and the existence of an additional zero-point offset, but none provide a sufficient reconciliation with both DEB distances. We conclude that the combination of the systematic uncertainties on the EDR3 parallaxes with the uncertainties on the effect of metallicity on the Cepheid distance scale leads to a systematic error floor of approximately 3%. We therefore find that the EDR3 data are not sufficiently accurate in the regime of these bright Cepheids to determine extragalactic distances precise to the 1% level at this time, in agreement with a number of contemporary studies.
First Images of Phosphorus Molecules toward a Protosolar Analog

Published: March 2022

The chemistry of phosphorus in star- and planet-forming regions is poorly understood, despite the central role of phosphorus in terrestrial biochemistry. We present Atacama Large Millimeter/submillimeter Array band 3 and 4 observations of PO and PN toward the Class I protostar B1-a, representing the first spatially resolved observations of phosphorus carriers toward a solar-type star-forming region. The phosphorus molecules emit from two distinct clumps, which coincide with regions where the protostellar outflow (traced by SiO) interacts with a filament of dense gas (traced by CCS). Thus, the gas-phase phosphorus seems to originate from the shocking of dense interstellar clumps. Based on the observed emission patterns, PO and PN appear to be daughter products of a solid phosphorus carrier with an intermediate volatility between ices and silicate grains. Interstellar shocks may therefore play an important role in converting semi-refractory phosphorus to a more volatile form prior to incorporation into cometary ices. Indeed, the (PO+PN)/CH3OH ratio is similar in B1-a and comet 67P, implying a comparable reservoir of volatile phosphorus. The PO/PN ratio ranges from ∼1–8 across B1-a. The northern emission clump exhibits a lower PO/PN ratio and weaker 13CH3OH emission than southern clump, indicating distinct shock physics and chemistry at the two positions. Resolved observations of P carriers toward additional sources are needed to better understand what regulates such variations in the PO/PN ratio in protostellar environments.
Measuring Spin from Relative Photon-ring Sizes

Published: March 2022

The direct detection of a bright, ring-like structure in horizon-resolving images of M87* by the Event Horizon Telescope (EHT) is a striking validation of general relativity. The angular size and shape of the ring is a degenerate measure of the location of the emission region, mass, and spin of the black hole. However, we show that the observation of multiple rings, corresponding to the low-order photon rings, can break this degeneracy and produce mass and spin measurements independent of the shape of the rings. We describe two potential experiments that would measure the spin. In the first, observations of the direct emission and n = 1 photon ring are made at multiple epochs with different emission locations. This method is conceptually similar to spacetime constraints that arise from variable structures (or hot spots) in that it breaks the near-perfect degeneracy between emission location, mass, and spin for polar observers using temporal variability. In the second, observations of the direct emission and n = 1 and n = 2 photon rings are made during a single epoch. For both schemes, additional observations comprise a test of general relativity. Thus, comparisons of EHT observations in 2017 and 2018 may be capable of producing the first horizon-scale spin estimates of M87* inferred from strong lensing alone. Additional observation campaigns from future high-frequency, Earth-sized, and space-based radio interferometers can produce high-precision tests of general relativity.
FRAMEx. II. Simultaneous X-Ray and Radio Variability in Active Galactic Nuclei—The Case of NGC 2992

Published: March 2022

Using simultaneous Very Long Baseline Array and Neil Gehrels Swift Observatory X-ray Telescope observations of the active galactic nucleus (AGN) in NGC 2992 over a six-month observing campaign, we observed a large drop in core 5 cm radio luminosity, by a factor of >3, in tandem with a factor of >5 increase in 2–10 keV X-ray luminosity. While NGC 2992 has long been an important object for studies of X-ray variability, our study is the first simultaneous X-ray and radio variability campaign for this object. We observe that the X-ray spectral index does not change over the course of the flare, consistent with a change in the bulk amount of Comptonizing plasma, potentially due to a magnetic reconnection event in the accretion disk. The drop in apparent radio luminosity can be explained by a change in free–free absorption, which we calculate to correspond to an ionized region with a physical extent and electron density consistent with the broad-line region (BLR). Our results are consistent with magnetic reconnection events in the dynamic accretion disk creating outbursts of ionizing material, increasing Compton up-scattering of UV accretion disk photons and feeding material into the BLR. These findings present an important physical picture for the dynamical relationship between X-ray and radio emission in AGNs.

BACKGROUND: Periodontitis is a chronic inflammatory disease that causes damage to the supporting structures of the teeth, and if left untreated, it can lead to impaired function, appearance, pain, and tooth loss. Periodontitis is caused by bacteria that adhere to and grow on the tooth surface. The “red complex” bacteria consisted of Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia. These bacteria will trigger an inflammatory response in the body. Interleukin-6 (IL-6) is an IL that acts both as a pro-inflammatory cytokine, IL-6 is a stimulator for MMP production. To treat the periodontal disease can be through non-surgical therapy as well as surgical therapy, to maximize therapy, it is accompanied by antimicrobial therapy. However, because of the frequent use of antimicrobials, causing antimicrobial resistance in patients, the use of natural ingredients as additional therapy is very necessary for this study using Moringa leaves as a substitute for antimicrobials.

AIM: This study aimed to determine the effectiveness of Moringa leaf in influencing the anti-inflammatory cytokine IL-6. The first benefit of this research is to provide scientific information in the field of dentistry regarding the effectiveness of Moringa leaves against red-complex bacteria P. gingivalis as a cause of chronic periodontitis through anti-inflammatory cytokine analysis.

METHODS: The type of research that will be used is quasi-experimental with a post-test research design with a control group design. This study used a sample consisted of 30 Wistars (Rattus novergicus) and was divided into two groups based on periodontal tissue sampling as follows treatment group which was treated with extracts Moringa and control group with aquadest irrigation after bacterial induction in the gingival sulcus. Blood samples were taken on days 0, 1, 3, 5, and 7 and centrifuged obtain blood serum and serum cytokine levels (pg/mL) were quantified using a commercial ELISA IL-6 kit.

RESULTS: This study obtained the results that there was a decrease in IL-6 in both groups on the 3rd day of observation (D3) where the treatment group given Moringa extract showed a greater decrease in IL-6 levels compared to the control group. There is a significant value in the comparison of IL-6 levels between the two groups with p-value: 0.000 (p < 0.05).

CONCLUSION: Moringa oleifera leaf extract showed the anti-inflammatory effect on inflammation induced by the bacterium P. gingivalis. M. oleifera extract can reduce the production of the pro-inflammatory cytokine IL-6 induced by P. gingivalis bacteria in periodontitis.

Authors: Wang Ming-Kai , Wang Cheng , Yin Jun-Feng
Published: March 2022

In order to reduce the oscillations of the numerical solution of fractional exotic options pricing model, a class of numerical schemes are developed and well studied in this paper which are based on the 4th-order Padé approximation and 2nd-order weighted and shifted Grünwald difference scheme. Since the spatial discretization matrix is positive definite and has lower Hessenberg Toeplitz structure, we prove the convergence of the proposed scheme. Numerical experiments on fractional digital option and fractional barrier options show that the (0, 4)-Padé scheme is fast, and significantly reduces the oscillations of the solution and smooths the Delta value.
Global dynamics of a modified Leslie-Gower predator-prey model with Beddington-DeAngelis functional response and prey-taxis
Authors: Tian Jialu , Liu Ping
Published: March 2022

In this paper, our purpose is to discuss the global dynamics of a modified Leslie-Gower predator-prey model with Beddington-DeAngelis functional response and prey-taxis under homogeneous Neumann boundary conditions. First, we derive that the global classical solutions of the system are globally bounded by taking advantage of the Morse's iteration of the parabolic equation, which further arrives at the global existence of classical solutions with a uniform-in-time bound. In addition, we establish the global stability of the spatially homogeneous coexistence steady states under certain conditions on parameters by constructing Lyapunov functionals.

Published: March 2022

Ecosystem services (ES) are the benefits people receive from ecosystems and a key tool for assessing the sustainability of natural resource use. Natural resource management requires consistent data on the state of ES; despite this, no such research has been carried out at the national level in Slovenia. The purpose of the article is to create an overview of past ES studies in Slovenia. The method of systematic mapping was used. We identified, compared, and described data on ES studies that have been published in Slovenia. The key findings are: 1) the number of ES studies in Slovenia is increasing, however the share of studies focused solely on ES has been decreasing since 2015; 2) the most represented field is forestry and the forest is the most commonly examined ecosystem; 3) the prevailing ES groups are regulating ES, while the most commonly explored individual ES are cultural ES, namely recreation and ecotourism, and 4) the most commonly implemented methodological approach is narrative analysis.

Ekosistemske storitve (ES) so koristi, ki jih ljudje prejemajo od ekosistemov, in so eno ključnih orodij za presojo trajnosti rabe naravnih virov. Za upravljanje z naravnimi viri so nujni konsistentni podatki o stanju ES, a takšne raziskave na nacionalni ravni v Sloveniji še ni. Namen članka je pregledati pretekle raziskave ES v Sloveniji. Uporabili smo metodo sistematičnega kartiranja. Identificirali, primerjali in opisali smo podatke o objavljenih raziskavah o ES v Sloveniji. Ključne ugotovitve so: 1) število raziskav ES v Sloveniji raste, a se od 2015 zmanjšuje delež osredotočenih zgolj na ES; 2) najbolj zastopano področje je gozdarstvo, gozd pa največkrat preučevan ekosistem; 3) med skupinami ES prednjačijo uravnalne, najpogosteje obravnavana posamezna ES je kulturna ES, in sicer rekreacija in ekoturizem; 4) najpogosteje uporabljen metodološki pristop je narativna analiza.

Published: March 2022

This qualitative study aims to examine the maturity level of Indonesian government institutions (IGI) and state-owned enterprises (SEO) in knowledge management (KM). KM maturity is measured using three KM components—people, process, and technology—and categorized using four levels—develop, standardize, optimize, and innovate. This research collected and analyzed various forms of qualitative data, such as secondary data, in-depth interviews, and observations. An integrative case study was conducted and resulted in a clear understanding of the implementation, level, and output of KM maturity in IGI and SEOs. Research findings can be broken down into two outputs: (1) The identification of KM implementation in IGI and SEOs, which formed the basis of our KM mapping plot. KM has become a strategy to manifest bureaucratic reform in IGI to become knowledgeable institutions in disruptive settings; (2) A method to propose KM maturity level. Future research could incorporate the efficacy variables of KM implementation and develop KM maturity typology criteria.

Sediment depositional environments are one of the important scientific bases in evaluation the reservoir potential of sedimentary rocks. This article focuses on studying this issue for Middle Miocene sediments, Thien Ung - Mang Cau structure, Block 04 - 3, Nam Con Son basin. The article has integrated the methods of well log interpretation, thin section analysis and seismic attribute analysis, combined with the results of paleontological analysis of VPI - Labs to identify depositional environments of Middle Miocene sediments in the case study area. The results of interpreting well log data show that the Middle Miocene sediments were deposited in the following environments: shallow marine, shoreline, mouth bars, delta front, prodelta and lower deltaic plain. These findings are also consistent with the results of petrographic and paleontological analysis. The results of petrographic analysis show that in the study area, there are 2 main groups of sedimentary rocks, which are clastic and carbonate rocks. In the thin sections, the following components were detected: glauconite clay is characterized of marine environment, carbonate fission and siderite ore which are characteristic of deltaic environments. While paleontological samples detected organic materials, such as algae, bitumen; and fossils such as Foraminifera, Da Gai and Oc Gai - typical for shallow marine environments. The results of the seismic attribute analysis for the Middle Miocene carbonate sediments of the structure have clarified that the carbonate is concentrated in the central and eastern uplift area. This distribution tends to fewer in the west. This finding is consistent when the authors compared to well correlation in the area (wells: C - 1X, C - 2X, C - 3X and C - 4X) and also logically with the sedimentary principles.

Nowadays, satellite remote sensing technology has been applied in many fields of socio-economic development, including search and rescue at sea. Systems with the integration of remote sensing satellite technology have made the search and rescue operations faster, more accurate and more efficient. With the search and rescue systems at sea, remote sensing satellite motion simulation is an important task. This helps the authorities to identify and select the appropriate remote sensing satellite image data source to assist in processing and zoning search and rescue at sea. However, in Vietnam, it is difficult to determine the satellite image data source for the search and rescue situations. Therefore, the research team built a remote sensing satellite motion simulation program based on two-line element data. This is the data source that has been used in astronomy research. This program will simulate satellite orbits in real time and at any time. The accuracy evaluation result of satellite orbit simulation have been compared with online remote sensing satellite tracking systems in the world. The research result show that the satellite orbit simulation has ensured accuracy.

The structural-phase state and durometric properties of gas-thermal Al-Fe-Cr-Ni pseudoalloy coatings have been studied. It is found that the sprayed coating is characterized by low porosity (up to 5 vol.%), low content of the austenite phase and iron and aluminum oxides. It is shown that the pseudoalloy hardness is HV10, and its microhardness is 450 HV0.025. The subsequent annealing of the composite coating in the temperature range of 350–550 °С leads to the precipitation of a large amount of strong intermetallic phases Fe13Al4 and Al5Fe2 in it. At the same time, the maximum hardness (220–230 HV10) of the Al-Fe-Cr-Ni coatings is recorded after annealing at 450 and 500 °C for 3–4 h, the maximum microhardness values (580–620 HV0.025) — after annealing at 500 and 550 °C for 2 h. Long-term exposure of coatings at elevated temperatures (500 and 550 °C) leads to a significant increase in their porosity (up to 20–50 vol.%).

ТРАНСВИТАЛЬНЫЙ СМЫСЛ В СТРУКТУРЕ СМЫСЛОВЫХ ОБРАЗОВАНИЙ ЛИЦ ПОЗДНЕГО ВОЗРАСТА

Published: March 2022

В статье рассматривается место трансвитального смысла в структуре смыслового образования лиц позднего возраста. Увеличение продолжи- тельности жизни человека во всем мире представляет не только социальную, но и психологическую проблему. Возникают серьезные основания пересмотреть устоявшиеся взгляды как на известные возрастные периодизации, так и на внутренний мир и деятельность пожилого человека. В системе концептуальных категорий отечественной возрастной психологии возникает необходимость амплификации понятий «ведущая деятельность» и «психологические новообразования». Трансвитальный смысл в системе смысловых образований личности позднего возраста характеризуется поиском и обретением новых смыслов, мотивирующих постпрофессио- нальную, социальную или иную активность на завершающем этапе жизни и реализацию постжизненного продолжения в тех или иных личных достижениях: оставить после себя память в делах, идеях, в созданных материальных и нематериальных ценностях, в потомках. Чувство нужности, принадлежности семье, ближайшему окружению, ощущение собственной ценности для общества позволяет человеку позднего возраста адаптиро- ваться и реализоваться на данном возрастном этапе. Отличительной особенностью лиц позднего возраста является осознание возможности виртуального продолжения жизни в тех или иных формах микро- и макро- групповой памяти. Поиск трансвитального смысла как выхода за пределы отдельной человеческой жизни на завершающей стадии может представ- лять собой интеграционную задачу смыслового оформления жизненного пути человека. Смысл жизни является особенной ценностью для человека позднего возраста.

We first examine people’s view on the role of Islamic political parties, and therefore explore their elite attitudes. Methodologically, this present study employs mix method, quantitative and qualitative research design. More specifically, this study is a case study. The case study is more appropriate for the analysis of this study. For data collection, the study utilizes the questionnaire, interview, and the documentary analysis. There are three steps of data analysis for qualitative data: reducing data, displaying data and drawing and verification. For quantitative data, the present study applies descriptive statistics to find out mean, standard deviation (SD), and percentage. The research findings indicate that the performance of Islamic political parties in Indonesia contemporary politics is still low and the Islamic political party voters are unsatisfactory on the Islamic political parties and their political elites.
