The Decoupling of Binaries from Their Circumbinary Disks
Authors: Dittmann Alexander J. , Ryan Geoffrey , Miller M. Coleman 
Published: June 2023

Abstract
We have investigated, both analytically and numerically, accreting supermassive black hole binaries as they inspiral due to gravitational radiation to elucidate the decoupling of binaries from their disks and inform future multimessenger observations of these systems. Our numerical studies evolve equal-mass binaries from initial separations of 100 GM/c until merger, resolving scales as small as ∼0.04 GM/c, where M is the total binary mass. Our simulations accurately capture the point at which the orbital evolution of each binary decouples from that of its circumbinary disk, and precisely resolve the flow of gas throughout the inspiral. We demonstrate analytically and numerically that timescale-based predictions overestimate the binary separations at which decoupling occurs by factors of ∼3, and illustrate the utility of a velocity-based decoupling criterion. High-viscosity (ν ≳ 0.03 GM/c) circumbinary systems decouple late (a

b
≲ 15 GM/c) and have qualitatively similar morphologies near merger to circumbinary systems with constant binary separations. Lower-viscosity circumbinary disks decouple earlier and exhibit qualitatively different accretion flows, which lead to precipitously decreasing accretion onto the binary. If detected, such a decrease may unambiguously identify the host galaxy of an ongoing event within a LISA error volume. We illustrate how accretion amplitude and variability evolve as binaries gradually decouple from their circumbinary disks, and where decoupling occurs over the course of binary inspirals in the LISA band. We show that, even when dynamically negligible, gas may leave a detectable imprint on the phase of gravitational waves.

Involvement of host iron-withholding strategy on Streptococcus pyogenes strain KSU-1 growth and pathogenicity
Authors: Alkhulaifi Manal M. , Al-Salamah Ali A. , Elgammal Eman W. , Ibrahim Abdelnasser S.S. 
Published: June 2023

Background and objectives

Streptococcus pyogenes is a highly adaptable human pathogen that can cause a wide spectrum of infections ranging from mild to a life-threating systemic infection. This study discussed the effectiveness of iron-depriving strategy on growth, survival, and virulence of S. pyogenes.

Materials and methods
Some comparisons between different iron-saturated and iron-depleted forms of the main human iron reservoirs (hemoglobin, hemin, transferrin, lactoferrin, and human milk) were tested for their effect on growth and pathogenicity of S. pyogenes.

Results and conclusion
Although the iron-saturated forms enhanced the growth and survival, the iron-free forms had a bacteriostatic/bactericidal activity against the microbe, and these results were emphasized by the in vivo study. Finally, the bacterial surface proteins as virulence factors were secreted upon iron depletion as indicated by sodium dodecyl sulfate polyacrylamide gel electrophoresis. This study proved that iron-depletion environment increased the resistance and virulence factors of S. pyogenes. Moreover, these results can give an insight about the interaction between the host and pathogen, which can lead to designing of new antimicrobial agents or vaccine that may target these pathways.

Published: June 2023

Introduction: 10-15% of diffuse large B-cell lymphomas (DLBCL) patients fail to achieve complete response (CR) after R-CHOP, and are considered primary refractory. There is limited transplant data in this population.
Objetive: to evaluate the outcomes of primary refractory DLBCL patients transplanted at our center.
Results: we evaluated 34 R/R patients treated with R-CHOP as first line. After second line, 30.4% of primary refractory/early relapse achieved CR, and 88.2% did so after ASCT. Median follow-up: 56.1 months, median OS was not reached; the estimated 5-year OS was 61.7%. Median OS of late relapse (Group 1) was not reached, and was 52 months for primary refractory/early relapse (Group 2) (p=0.023). The 5-year OS was 87.5% in Group 1 vs 49% in Group 2 (p=0.023).
Conclusions: Primary refractory and early relapsed DLBCL undergoing second-line therapy and ASCT have worse OS compared to late relapse. However, 49% of primary refractory patients who proceeded to ASCT had prolonged survival, which supports the role of ASCT in this population.

Published: June 2023

Objective: Centers in resource-limited countries face significant challenges in performing unrelated donor allogeneic stem cell transplantation. We analyze the outcome of concrete actions taken by our program since 2008 to gain access to worldwide transplant donors, select and procure the preferred donor for our patients, and perform the transplant timely.
Methods: We focused on three aspects to gain unlimited access to unrelated donors: hiring and training dedicated nurse coordinators, establishing fluid communication and collaboration with donor registries and cord blood banks, and careful planning of the transplant procedure to avoid delays. We describe the evolution of donor choice since 2008 and the time to transplantation between related (matched sibling and haploidentical) and unrelated (adult and cord blood) donors.
Results: We transplanted 238 children between 2008 and 2022. Transplant activity increased from 28 procedures in 2008-2010 to 85 in 2020-2022, mainly at the expense of unrelated donors. The proportion of unrelated donors between both periods increased from 14% to 65% as cord blood usage decreased from 65% to 9% (p<0,001). DKMS donor centers provided 60% of the products. The mean time to transplantation was 68 days for related donors (MSD and haploidentical) and 74 days for unrelated donors (MUD, MMUD, UCB).
Conclusion: Despite practicing in a limited resource setting, specific actions allowed us to overcome difficulties in search, procurement, and timely transplantation.

Published: June 2023

PROBLEMA: actualmente la red social más utilizada por las personas es el Facebook y se ha observado que algunos usuarios especialmente los jóvenes dependen de la red social por falta de control y disciplina. OBJETIVO: evidenciar si el uso constante del Facebook provoca ansiedad o adicción en los usuarios. MÉTODO: se realizó el estudio con enfoque cuantitativo y alcance descriptivo, se tomó una muestra de 43 estudiantes de la carrera de Derecho del Centro Universitario de Sololá a quienes se les aplicó una encuesta. RESULTADOS: se evidenció que el 99% de los encuestados (42) tienen activada una cuenta en Facebook y ocupan en promedio media hora al día para revisar las noticias y muros de los amigos. La mayoría indicaron que el uso es satisfactorio para sus intereses a pesar de que en algunos ocasiona dolor de cabeza y de ojos. Únicamente el 10% de los estudiantes (4) indicaron tener dependencia a la red social Facebook. CONCLUSIÓN: es necesario tener disciplina para usar Facebook, si bien es cierto que ha significado un medio para acercar a las personas, para la libertad de expresión y sentimientos a través de diferentes opciones, no hay una cultura digital para su uso de forma responsable.

The regional government allocates funds in the form of regional budgets in the APBD to increase fixed assets. So far, regional spending has been used more for routine spending which is relatively less productive. The purpose of this study is to analyze the effect of Regional Original Income (PAD), General Allocation Fund (DAU), Special Allocation Fund (DAK), and Profit Sharing Fund (DBH) on regional Expenditure Allocation in Bima City government. The population of this study is the financial report of the Bima City APBD realization for 17 years starting from 2004 to 2021, while the research sample uses 5 years, which is from 2017 to 2021. The secondary data used in this research is the Bima City Government APBD Realization Report. Hypothesis testing in this study used Smart PLS. Research shows that PAD and DAU have a significant effect on economic growth. However, PAD and DAU have no effect on Regional Spending, and Regional Expenditure cannot mediate the influence of PAD and DAU on economic growth. The results showed that there was no flypaper effect phenomenon in the Bima City Government Budget.

The low level of MSME taxpayer compliance is one of the causes of not optimal tax revenue in Indonesia. The total MSME actors reached 64.2 million while the number of MSME actors registered as taxpayers was only 2.31 million or 3.6% of MSMEs registered as taxpayers was only 15%, which means that the level of MSME taxpayer compliance is still low. So in order to increase taxpayer compliance, one of the efforts made by the Government together with the DPR was the issuance of the Law on the Harmonization of Tax Regulations (UU HPP) no.7 years 2021. The purpose of this study was to determine the effect of MSME taxpayers' perceptions of the HPP law and to determine the effect of tax socialization on taxpayer compliance. This research data is primary data by providing questionnaires directly and online using the Google form to MSMEs in North Sumatra. The sampling technique used purposive sampling method. And the hypothesis test used is multiple regression analysis. The results show that the perceptions of MSME taxpayer on the HPP Law have a positive and significant effect on MSME Taxpayer compliance. MSME taxpayers who have a positive perception of the HPP Law accept the decision so that MSME taxpayer compliance is also positive. Meanwhile, tax socialization has no effect on MSME taxpayer compliance. This is because MSME taxpayers follow the tax socialization invitation from Direktorat Jendaral pajak (DJP), and most of the research samples are DJP assisted MSMEs, so the socialization is only a formality, the material obtained is only listened to and MSME taxpayers are more enthusiastic about participating in training related to development his skills.It is hoped that this research can be used as a source of information for MSME taxpayers in making decisions on taxpayer perceptions of the HPP Law which will affect the level of taxpayer compliance and the development of taxation theory.

Authors: Maulana Nora , Zulfahmi Zulfahmi 
Published: June 2023

The low level of public literacy related to Islamic economics causes errors and mistakes in the practice of Islamic economics, so that if it is ignored it can have a negative impact on the development and progress of Islamic economics itself. So it is important for various parties to know and study various models of economic thought concepts from Islamic economists such as Yusuf Qardhawi. Because the concept of Islamic economic thought can be used as a reference in dealing with economic problems. Yusuf Qardhawi's phenomenal economic thought is related to professional zakat, ethics and economic norms which include the ethical concepts of production, distribution, and consumption. Not only that, but Yusuf Qardhawi also expressed his phenomenal thoughts related to the concept of property which includes zakat, taxes, interest and usury, the concept of working in Islam, government involvement in economic ethics, and also the concept of equitable distribution of welfare for all people. Although it contains various pros and cons, the journey of professional zakat in Indonesia has attracted a lot of attention from various groups ranging from academics, scholars and the government who are also serious about responding to this phenomenon, especially MUI with the issuance of Law No. 3 of 2003 concerning Income Zakat, Law No. 23 of 2011 concerning Zakat Collection, PMA and BAZNAS also participate to strengthen regulations and policies on professional zakat regulation.
