Authors: De Oliveira Juliê Pena , Zanoni Vanda Alice Garcia , Da Fonseca Pedro Pellegrino 
Published: September 2022

O presente artigo é uma pesquisa sobre o uso de HBIM para o levantamento e documentação do Patrimônio Cultural, em que o objeto de estudo foi a Igreja Nossa Senhora de Fátima, localizada em Brasília, Distrito Federal. O levantamento arquitetônico foi feito com Scanner à Laser. A partir da nuvem de pontos gerada, foi feita a modelagem 3D utilizando o software Revit. O objetivo deste trabalho é analisar o Nível de Desenvolvimento (LOD) empregado na modelagem, com base no padrão desenvolvido pelo American Institute of Architects (AIA). Foi possível notar que a ausência de documentação pode influenciar na modelagem 3D, por não ter informações suficientes para gerar um modelo HBIM. Portanto, reunir informações no modelo pode contribuir para a preservação patrimonial de forma mais efetiva ao longo do seu ciclo de vida. O uso de ferramentas como o LOD pode tornar o processo de documentação mais acurado e transparente, melhorando a qualidade de comunicação entre os usuários do modelo e pesquisadores.

Published: September 2022

La Contabilidad Gubernamental ha sido un tema de competencia de distintas instancias de los gobiernos: federal, estatal y municipal, así como de entidades de fiscalización y control. La importancia de este trabajo es la transparencia y acceso a la información, que surge como una demanda ciudadana de informar sobre los recursos públicos, avances y desempeño que obliga a los administradores a apoyarse de sistemas de registro contable y presupuestal que brinde información financiera confiable, oportuna, que permita al ciudadano ver las evidencias del quehacer de los funcionarios públicos, apegados a las normas de información financiera. El objetivo: Promover y analizar el grado de avance de la administración pública en materia de Contabilidad Gubernamental y armonizar la presentación de los informes financieros de los entes públicos de todos los niveles de gobierno. Metodología fue a través de la revisión documental del marco normativo y conocer cuáles son las atribuciones conferidas al Consejo Estatal de Armonización contable, se analizó el aspecto operativo, lineamientos, postulados básicos, manuales contables y los aspectos generales establecidos por las normas internacionales y nacionales para el sector público. Se concluye que los organismos públicos han llevado adaptaciones tanto en sus sistemas de información como en los criterios de registros contables, con el fin de lograr una adecuada armonización. Actualmente todavía no es factible generar información armonizada, de manera automática y en tiempo real. Para efectos de auditoría se señala que se respeta la estructura de la cuenta pública, sin contener información consolidada, notas a los estados financieros relacionadas con esquemas bursátiles y de cobertura financiera. Existen problemas con el personal y se tiene una inadecuada coordinación entre los organismos involucrados.

Published: September 2022

<p>Ecosystems of multiple blockchains are now a reality. Multi-chain applications and protocols are perceived as necessary to enable scalability, privacy, and composability. Despite being a promising emerging research area, we recently have witnessed many attacks that have caused billions of dollars in losses. Attacks against bridges that connect chains are at the top of such attacks in terms of monetary cost, and no apparent solution seems to emerge from the ongoing chaos. </p>
<p>In this paper, we present our contribution to minimizing bridge attacks. In particular, we explore the concepts of <em>cross-chain transaction, cross-chain logic, </em>and the<em> cross-chain state</em> as the enablers of the cross-chain model. We propose <strong>Hephaestus</strong>, the first cross-chain model generator that captures the operational complexity of cross-chain applications. <strong>Hephaestus</strong> can generate cross-chain models from local transactions on different ledgers realizing arbitrary use cases and allowing operators to monitor their cross-chain applications. Monitoring helps identify outliers and malicious behavior, which can help programmatically to stop bridge hacks and other attacks. We conduct a detailed evaluation of our system, where we implement a cross-chain bridge use case. Our experimental results show that <strong>Hephaestus </strong>can process 600 cross-chain transactions in less than 5.5 seconds in an environment with two blockchains and requires sublinear storage.</p>

In the first week of March 2020, as the COVID-19 pandemic spread worldwide, fourteen American travelers spent a week in Morocco. The researchers analyzed electronic correspondence, journals, recorded discussions among program participants, and interviews. The data suggest that (a) participants experienced culture shock very early in the trip, (b) travel disruptions (especially luggage loss) affected program participants more than COVID, (c) the program leaders concentrated on problems they felt they could solve, (d) exhaustion and stress were prevalent themes for the program leaders, and (e) the program leaders experienced doubt and confusion while helping program participants. We recommend that study abroad officials reexamine faculty and students' preparation and emergency procedures and avoid over-relying on third-party providers. We conclude that during a crisis, problem-focused coping can be a stress-reducing mechanism for study abroad program participants.

Abstract in Spanish
En la primera semana de marzo de 2020, cuando la pandemia de COVID-19 se extendió por todo el mundo, catorce viajeros estadounidenses pasaron una semana en Marruecos. Los investigadores analizaron la correspondencia electrónica, los diarios, las conversaciones grabadas entre los participantes del programa y las entrevistas. Los datos sugieren que (a) los participantes experimentaron un choque cultural muy temprano en el viaje, (b) las interrupciones del viaje (especialmente la pérdida de equipaje) afectaron a los participantes del programa más que el COVID, (c) los líderes del programa se concentraron en los problemas que sintieron que podían resolver, (d) el agotamiento y el estrés fueron temas predominantes para los líderes del programa, y ​​(e) los líderes del programa experimentaron dudas y confusión mientras ayudaban a los participantes del programa.

This study examines whether variations in ownership structure, board characteristics, and financial distress have an impact on the level of tax avoidance in Indonesia. Independent variables included in the study are family ownership, institutional ownership, managerial ownership, foreign ownership, the composition of the board of commissioners, the independence of the board of commissioners, the frequency of board meetings, and financial distress. Effective tax rate (ETR) and cash flow effective tax rate (CFETR) act as a measurement to determine the dependent variable namely tax avoidance. Control variables are firm size, profitability, leverage, and market to book value.
This study is designed as a causal-comparative study in which the relationship of each variable is tested. The population consists of all companies listed on the IDX in the 2014-2018 period. Listed companies are classified based on specified criteria to obtain observations of 460 data for ETR and 506 data for CFETR. The data are processed to form hypotheses using descriptive methods and regression methods.
The research concludes that managerial ownership, the composition of the board of commissioners and financial distress negatively affect tax avoidance. While family ownership, institutional ownership, foreign ownership, independence of the board of commissioners and the frequency of board meetings do not have a significant relationship to the practice of tax avoidance.

Published: September 2022

This study looked at the capacity development requirements of Home Economics teachers in South East Nigeria for computer-assisted pattern drafting training. A research question and a hypothesis led the investigation. Ex-post facto research was used in this study. A total of 131 Home Economics lecturers from universities, polytechnics, and colleges of education in South East Nigeria were included in the study. Because of its manageable size, the complete population was investigated, so there was no sampling. Capacity Building Needs for Computer Assisted Teaching Questionnaire (CBNCATQ) was used for data collection. The instrument was face validated and tested for internal consistency using Cronbach Alpha Coefficient. Data obtained from the respondents were analyzed using Statistical Package for Social Science (SPSS). Percentage, mean scores and standard deviation were used to answer the research question while the hypothesis was tested with a t-test at a 0.05 level of significance. The results of this study showed that training on the use of computers, ability to use various pattern drafting materials and equipment, availability of electricity to power equipment, and ability to follow basic principles of pattern drafting among others were capacity building needs of lecturers. Based on the findings, it was recommended among others that lecturers should be given opportunities for in-service training on computer usage and workshops should be organized for the lecturers on the benefits of using computers in teaching.

3D Orbital Architecture of a Dwarf Binary System and Its Planetary Companion

Published: September 2022

Abstract
Because of the diversity of stellar masses and orbital sizes of binary systems and the complex interaction between star–star, star–planet, and planet–planet, it has been difficult to fully characterize the planetary systems associated with binary systems. Here, we report high-precision astrometric observations of the low-mass binary system GJ 896AB, revealing the presence of a Jupiter-like planetary companion (GJ 896Ab). The planetary companion is associated to the main star GJ 896A, with an estimated mass of 2.3 Jupiter masses and an orbit period of 284.4 days. A simultaneous analysis of the relative astrometric data obtained in the optical and infrared with several telescopes, and the absolute astrometric data obtained at radio wavelengths with the Very Long Baseline Array (VLBA), reveals, for the first time, the fully characterized three-dimensional (3D) orbital plane orientation of the binary system and the planetary companion. The planetary and binary orbits are found to be in a retrograde configuration and with a large mutual inclination angle (Φ = 148°) between both orbital planes. Characterizing the 3D orbital architecture of binary systems with planets is important in the context of planet formation, as it could reveal whether the systems were formed by disk fragmentation or turbulence fragmentation, as well as the origin of spin–orbit misalignment. Furthermore, as most stars are in binary or multiple systems, our understanding of systems such as this one will help to further understand the phenomenon of planetary formation in general.

Abstract
We image the spatial extent of a cool galactic outflow with fine-structure Fe ii* emission and resonant Mg ii emission in a gravitationally lensed star-forming galaxy at z = 1.70347. The Fe ii* and Mg ii (continuum-subtracted) emissions span out to radial distances of ∼14.33 and 26.5 kpc, respectively, with maximum spatial extents of ∼21 kpc for Fe ii* emission and ∼30 kpc for Mg ii emission. Mg ii emission is patchy and covers a total area of ∼184 kpc2, constraining the minimum area covered by the outflowing gas to be ∼13% of the total area. Mg ii emission is asymmetric and shows ∼21% more extended emission along the decl. direction. We constrain the covering fractions of the Fe ii* and Mg ii emission as a function of radial distance and characterize them with a power-law model. The Mg ii 2803 emission line shows two kinematically distinct emission components and may correspond to two distinct shells of outflowing gas with a velocity separation of Δv ∼ 400 km s−1. By using multiple images with different magnifications of the galaxy in the image plane, we trace the Fe ii* and Mg ii emissions around three individual star-forming regions. In all cases, both the Fe ii* and Mg ii emissions are more spatially extended compared to the star-forming regions traced by the [O ii] emission. These findings provide robust constraints on the spatial extent of the outflowing gas and, combined with outflow velocity and column density measurements, will give stringent constraints on mass-outflow rates of the galaxy.

Published: September 2022

Abstract
We have developed a chemodynamical approach to assign 36,010 metal-poor SkyMapper stars to various Galactic stellar populations. Using two independent techniques (velocity and action space behavior), Gaia EDR3 astrometry, and photometric metallicities, we selected stars with the characteristics of the “metal-weak” thick-disk population by minimizing contamination by the canonical thick disk or other Galactic structures. This sample comprises 7127 stars, spans a metallicity range of −3.50 < [Fe/H] < −0.8, and has a systematic rotational velocity of 〈V

. Overall, we find a significant metal-poor component consisting of 261 SkyMapper stars with [Fe/H] < −2.0. While our sample contains only 11 stars with [Fe/H] ≲ −3.0, investigating the JINAbase compilation of metal-poor stars reveals another 18 such stars (five have [Fe/H] < −4.0) that kinematically belong to our sample. These distinct spatial, kinematic, and chemical characteristics strongly suggest that this metal-poor, phase-mixed kinematic sample represents an independent disk component with an accretion origin in which a massive dwarf galaxy radially plunged into the early Galactic disk. Going forward, we propose to call the metal-weak thick-disk population the Atari disk, given its likely accretion origin, and in reference to it sharing space with the Galactic thin and thick disks.
The Details of Limb Brightening Reveal the Structure of the Base of the Jet in M87 for the First Time
Authors: Punsly Brian 
Published: September 2022

Abstract
It has become commonplace in astronomy to describe the transverse coarse structure of jets in loosely defined terms such as “sheath” and “spine” based on discussions of parsec scale properties. But, the applicability, dimension, and prominence of these features on sub-light-year scales has previously been unconstrained by observation. The first direct evidence of jet structure near the source in M87 is extreme limb brightening (a double-rail morphology), 0.3–0.6 mas from the source, which is prominent in observations with high resolution and sensitivity. Intensity crosscuts of these images provide three strong, interdependent constraints on the geometry responsible for the double-rail morphology: the rail to rail separation, the peak to trough intensity ratio, and the rail widths. Analyzing these constraints indicates that half or more of the jet volume resides in a thick-walled, tubular, mildly relativistic, protonic jet only ∼0.25 lt-yr (or ∼300 M, where M is the central black hole mass in geometrized units) from the source. By contrast, the Event Horizon Telescope Collaboration interprets their observations with the aid of general relativistic magnetohydrodynamic simulations that produce an invisible (by construction) jet with a surrounding luminous, thin sheath. Yet, it is shown that synthetic images of simulated jets are center brightened 0.3–0.6 mas from the source. This serious disconnection with observation occurs in a region previously claimed in the literature to be well represented by the simulations. The limb brightening analysis motivates a discussion of possible simulation modifications to improve conformance with observations.

Abstract
Studying the physical and chemical properties of cold and dense molecular clouds is crucial for the understanding of how stars form. Under the typical conditions of infrared dark clouds, CO is removed from the gas phase and trapped onto the surface of dust grains by the so-called depletion process. This suggests that the CO-depletion factor (f

D
) can be a useful chemical indicator for identifying cold and dense regions (i.e., prestellar cores). We have used the 1.3 mm continuum and C18O (2–1) data observed at the resolution of ∼5000 au in the ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES) to construct averaged maps of f

D
in 12 clumps to characterize the earliest stages of the high-mass star formation process. The average f

D
determined for 277 of the 294 ASHES cores follows an unexpected increase from the prestellar to the protostellar stage. If we exclude the temperature effect due to the slight variations in the NH3 kinetic temperature among different cores, we explain this result as a dependence primarily on the average gas density, which increases in cores where protostellar conditions prevail. This shows that f

D
determined in high-mass star-forming regions at the core scale is insufficient to distinguish among prestellar and protostellar conditions for the individual cores and should be complemented by information provided by additional tracers. However, we confirm that the clump-averaged f

D
values correlate with the luminosity-to-mass ratio of each source, which is known to trace the evolution of the star formation process.
