Authors: Nengsih Ifelda , Rizal Rizal 
Published: September 2022

Abstract
This research aims to uncover the risk management and management system carried out by PT. BPR Syariah Al-Makmur against mudharabah deposit products. This type of research is qualitative with descriptive methods. Data is collected through interviews and documentation to get an overview of the research. This study found that deposits became a superior product because deposits could take funds even if they were not due and were not subject to fines (penalties). To avoid liquidity risks due to withdrawal of funds before maturity, management develops various strategies. The liquidity risk management strategy developed in sequence is through a persuasive approach, namely by giving ababa, requesting 1 to 3 days if the funds are insufficient and providing facilities for the delivery of funds to the customer's residence. The preventive strategy of handling liquidity risk is to predict the needs of funds by carrying out daily monitoring of funds so that the stock of funds is carried out, also through the asset liquidity approach and repressive approach. Become a new model of deposit management carried out by PT. BPR Syariah Al-Makmur because no other financial institution has done anything like this. This model proved to be the largest source of funds compared to ordinary savings from 2012 to 2018. Although the number of deposits has decreased from 2017 to 2019. Even in 2019 the number of deposits is lower than ordinary savings, but this is an interesting thing to study further why this can happen.

Una lectura de la antropología borgiana: Las ovejas de César Aira
Authors: Arce Rafael 
Published: September 2022

Este trabajo propone una lectura de la primera novela de César Aira, Las ovejas, escrita en 1970 y publicada en 1984. Para ello, se atiende la relación de este texto con la obra de Jorge Luis Borges, partiendo de una conjetura genealógica que el mismo Aira sugiere. En esta genealogía, la animalidad cumple un papel determinante que explica el recorte intertextual del desenlace de la novela. Nuestra hipótesis afirma que es posible leer Las ovejas como una versión de la “antropología borgiana”, tal como la denominó Jaime Rest. En esta versión, la novela de Aira desplaza el presupuesto humanista del idealismo de Borges. Esta conjetura permite revisar el “vitalismo” de la obra de Aira y pensarlo, no en clave de “darwinismo”, como ha sido leído, sino en relación con la obra de Samuel Butler. Finalmente, esta lectura propone replantear los términos en los que se ha pensado la poética del olvido en Aira.
On the Origin of the Photospheric Magnetic Field
Authors: Schuck Peter W. , Linton Mark G. , Knizhnik Kalman J. , Leake James E. 
Published: September 2022

Abstract
This article presents results that challenge the paradigms that (1) the convection zone is the source of the radial magnetic field in the photosphere and (2) that coronal currents are neutralized from the perspective of the photosphere. We demonstrate, using a new analysis tool applied to simulations and observations, that bare or partially dressed current channels are supported by the solar corona and that fingerprints of these coronal current systems can be detected in the photosphere. These coronal current channels can be a significant source of the radial component of the magnetic field in the photosphere. The roots of these coronal current channels in the photosphere are the source of the magnetic field component parallel to the polarity inversion line in active region NOAA 12673. These analyses and observations transform our theoretical understanding of coronal evolution and argue for a reexamination of the present paradigm in which the convection zone is the sole source of the photospheric magnetic field.
Quasars with Periodic Variability: Capabilities and Limitations of Bayesian Searches for Supermassive Black Hole Binaries in Time-domain Surveys

Published: September 2022

Abstract
Supermassive black hole binaries (SMBHBs) are an inevitable consequence of galaxy mergers. At sub-parsec separations, they are practically impossible to resolve, and the most promising technique is to search for quasars with periodic variability. However, searches for quasar periodicity in time-domain data are challenging due to the stochastic variability of quasars. In this paper, we used Bayesian methods to disentangle periodic SMBHB signals from intrinsic damped random walk (DRW) variability in active galactic nuclei light curves. We simulated a wide variety of realistic DRW and DRW+sine light curves. Their observed properties are modeled after the Catalina Real-time Transient Survey (CRTS) and expected properties of the upcoming Legacy Survey of Space and Time (LSST) from the Vera C. Rubin Observatory. Through a careful analysis of parameter estimation and Bayesian model selection, we investigated the range of parameter space for which binary systems can be detected. We also examined which DRW signals can mimic periodicity and be falsely classified as binary candidates. We found that periodic signals are more easily detectable if the period is short or the amplitude of the signal is large compared to the contribution of the DRW noise. We saw similar detection rates both in the CRTS and LSST-like simulations, while the false-detection rate depends on the quality of the data and is minimal in LSST. Our idealized simulations provide an excellent way to uncover the intrinsic limitations in quasar periodicity searches and set the stage for future searches for SMBHBs.

Abstract
We present integral field spectroscopic observations of NGC 5972 obtained with the Multi-Unit Spectroscopic Explorer at the Very Large Telescope. NGC 5972 is a nearby galaxy containing both an active galactic nucleus (AGN) and an extended emission-line region (EELR) reaching out to ∼17 kpc from the nucleus. We analyze the physical conditions of the EELR using spatially resolved spectra, focusing on the radial dependence of ionization state together with the light-travel time distance to probe the variability of the AGN on ≳104 yr timescales. The kinematic analysis suggests multiple components: (a) a faint component following the rotation of the large-scale disk, (b) a component associated with the EELR suggestive of extraplanar gas connected to tidal tails, and (c) a kinematically decoupled nuclear disk. Both the kinematics and the observed tidal tails suggest a major past interaction event. Emission-line diagnostics along the EELR arms typically evidence Seyfert-like emission, implying that the EELR was primarily ionized by the AGN. We generate a set of photoionization models and fit these to different regions along the EELR. This allows us to estimate the bolometric luminosity required at different radii to excite the gas to the observed state. Our results suggest that NGC 5972 is a fading quasar, showing a steady gradual decrease in intrinsic AGN luminosity, and hence the accretion rate onto the SMBH, by a factor ∼100 over the past 5 × 104 yr.
Do Cellular Automaton Avalanche Models Simulate the Quasi-periodic Pulsations of Solar Flares?
Authors: Farhang Nastaran , Shahbazi Farhad , Safari Hossein 
Published: September 2022

Abstract
Quasi-periodic pulsations (QPPs) with various periods that originate in the underlying magnetohydrodynamic processes of flaring structures are detected repeatedly in solar flare emissions. We apply a 2D cellular automaton (CA) avalanche model to simulate QPPs as a result of a repetitive load/unload mechanism. We show that the frequent occurrence of magnetic reconnections in a flaring loop could induce quasi-periodic patterns in the detected emissions. We find that among 21,070 simulated flares, 813 events last over 50 s, scaled with the temporal resolution of the Yohkoh Hard X-ray Telescope, and about 70% of these rather long-lasting events exhibit QPPs. We also illustrate that the applied CA model provides a wide range of periodicities for QPPs. Furthermore, we observe the presence of multiple periods in nearly 50% of the cases by applying the Lomb–Scargle periodogram. A lognormal distribution is fitted to the unimodal distribution of the periods as a manifestation of an underlying multiplicative mechanism that typifies the effect of the system’s independently varying parameters. The global maximum of the periods’ lognormal distribution is located at 29.29 ± 0.67 s. We compare statistics of the simulated QPPs with parameters of the host flares and discuss the impacts of flare properties on the periods of QPPs. Considering the intrinsic characteristic of CA models, namely the repetitive load/unload mechanism, and the obtained pieces of evidence, we suggest that CA models may generate QPPs. We also examine the applicability of autoregressive integrated moving average models to describe the simulated and observed QPPs.

Abstract
Modeling of frequency-dependent effects, contributed by the turbulence in the free electron density of interstellar plasma, is required to enable the detection of the expected imprints from the stochastic gravitational-wave (GW) background in pulsar timing data. In this work, we present an investigation of temporal variations of interstellar medium for a set of millisecond pulsars (MSPs) with the upgraded Giant Metrewave Radio Telescope (GMRT) aided by large fractional bandwidth at lower observing frequencies. Contrary to the conventional narrowband analysis using a frequency-invariant template profile, we applied PulsePortraiture-based wide-band timing analysis while correcting for the evolution of the pulsar profile with frequency. Implementation of the PulsePortraiture-based wide-band timing method for the GMRT-discovered MSPs to probe the dispersion measure (DM) variations resulted in a DM precision of 10−4 pc cm−3. In general, we achieve similar DM and timing precision from wide-band timing compared to the narrowband timing with matching temporal variations of DMs. This wide-band timing study of newly discovered MSPs over a wide frequency range highlights the effectiveness of profile modeling at low frequencies and probes the potential of using them in a pulsar timing array.

Even nearly two years after the first reported case, the novel coronavirus (SARS-CoV-2) continues to ebb and flow around the world. A retrospective cohort study was carried out to determine the clinico-epidemiological profile and outcome of the cases. The study analyzed secondary data from 827 patients who presented to our center with COVID-19-related illnesses between December 15, 2021, and February 15, 2022 (third wave in India). There was a significant difference in the vaccination status of patients treated at home and those admitted, with 87.9% having received two doses compared to 74% in the second group being unvaccinated. Patients who were isolated at home recovered at a rate of 99.4%, while hospitalized patients died at a rate of 26.5%. Vaccination reduces the severity of COVID-19; however, constant vigilance for new variants, precautionary measures, and increased vaccination drives are critical moving forward.

Authors: Pratama Umar Tungki , Siburian Reynold 
Published: September 2022

Introduction: Coronavirus disease 2019 (COVID-19) is the cause of undergoing pandemic. Molecular testing in the form of reverse transcription-polymerase chain reaction (RT-PCR) is considered as the diagnostic standard for detecting COVID-19. However, there are still certain issues with its application. We sought this study is to systematically review and summarize studies pertaining blood laboratory biomarkers for diagnosing COVID-19. Methods: The systematic review was conducted by following the PRISMA 2020 recommendations. We searched published articles in four databases (EbscoHost, Pubmed, Science Direct, and Scopus).that assessed the implementation of routine laboratory tests examination for diagnosing COVID-19 patients from March 2020 through September 2021. Results: Three studies were selected to be reviewed, with the number of participants ranging from 100 to 485 (total: 792). Peripheral blood count parameters were assessed in all studies. The monocyte-lymphocyte ratio had the highest accuracy. Several abnormalities of laboratory indicators such as white blood cell, neutrophil, lymphocyte, eosinophil, NLR, MLR, LDH, AST, ALT, and CRP were significantly different between COVID-19 positive patients to negative controls,. Conclusion: No single test could identify or distinguish COVID-19 from other pneumonia causes. However, laboratory biomarkers can be used as a complement to the COVID-19 diagnostic approach.
