El trabajo de cuidar. Enfermeras, cuidados y profesionalización en Chile, 1900-1950
Authors: González Moya Maricela , Zárate Campos María Soledad
Published: July 2021

El presente artículo ofrece una reflexión sobre el proceso de profesionalización de la enfermería en Chile, utilizando la noción de “cuidados” como clave de interpretación para examinar las características y el desarrollo de dicho proceso. Se sostiene que la enfermería profesional, concebida como un oficio auxiliar de la medicina, fue estrechamente vinculada a ciertas aptitudes atribuidas a la condición femenina, e inscritas en el horizonte emocional de brindar atención a personas pobres y enfermas, a fin de suplir necesidades físicas y ofrecer tratamientos asistenciales formales. Más que una carga afectiva, las enfermeras soportaron sobre todo un peso normativo, el que fue transitando desde un conjunto de obligaciones vinculadas a las nociones de vocación y estándares de moralidad, hasta configurarse en un conjunto de habilidades propiamente técnicas que exigían preparación y formación sistemática.

Authors: Vosne Martins Ana Paula
Published: July 2021

O artigo realiza uma discussão conceitual do cuidado e um levantamento parcial e incompleto da produção historiográfica sobre as múltiplas dimensões do cuidado no contexto latino-americano, destacando as abordagens de gênero e de história das mulheres. A primeira parte do artigo trata das transformações históricas e culturais da noção de cuidado, a começar pela ambigüidade semântica e suas correlações éticas e morais, como também as diferentes abordagens do cuidado na tradição filosófica e literária ocidental. Discute-se ainda a crítica feminista ao cuidado como trabalho reprodutivo e naturalizado e as contribuições teóricas feministas ao debate sobre a ética do cuidado. A segunda parte do artigo faz um ajuste de foco para a produção historiográfica sobre o cuidado numa abordagem relativa ao gênero a partir de uma seleção parcial de estudos realizados no Brasil, na Argentina e no Chile.
Asistir sin ventanillas: el trabajo estatal de trinchera en tiempos de COVID-19
Authors: Arcidiácono Pilar , Perelmiter Luisina
Published: July 2021

El aislamiento social, preventivo y obligatorio (ASPO) como respuesta a la COVID-19 implicó múltiples desafíos para el Estado argentino en sus distintas áreas y jurisdicciones. Quienes forman parte de las agencias vinculadas con asistencia inmediata se enfrentaron durante la cuarentena con un fenómeno inédito: atender demandas minimizando la presencialidad. Este artículo reconstruye las reconversiones del trabajo socio-asistencial del Estado en organismos de nivel nacional y del área metropolitana de Buenos Aires durante los primeros tres meses de aislamiento. El desarrollo se concentra en los efectos que este tuvo sobre tres aspectos del trabajo estatal. Primero, sobre la organización interna del trabajo de asistencia, en términos de las divisiones jerárquicas y funcionales de roles y actividades. Segundo, sobre la dimensión simbólica de la autoridad estatal frente a la ruptura de los hábitos, instrumentos y escenas de oficialidad. Finalmente, sobre la interfaz con la sociedad, esto es, sobre las mediaciones sociales que canalizaron la asistencia en el marco de transferencias masivas y presuntamente automatizadas.
Assessment practices during Covid-19: the confluence of assessment purposes, quality and social justice in higher education
Authors: Padayachee Kershree , Matimolane Mapula
Published: July 2021

The Covid-19 pandemic necessitated an abrupt shift to emergency remote teaching and learning (ERT&L) in higher education institutions across the globe. In this shift, assessment and feedback, widely regarded as the heart of student learning experiences and a gauge of quality teaching pre Covid-19, became a major source of discontent and challenge for students and staff. In this paper, we present our reflections of observed and reported practices of assessment by staff and students, from the vantage point of our roles as facilitators of various professional development initiatives within our institution. We suggest that the challenges experienced during ERT&L reveal the entrenched view of assessment as gatekeeping and conceptions of quality as exceptional. We further contend that assessment strategies based on such a view during ERT&L may have further marginalized and disadvantaged students faced with digital/technological, economic, and socio-cultural access issues. However, we also highlight that despite the challenges for students and staff, the experience may have broadened lecturers’ views of their role in addressing the ongoing social justice challenges of access, and the power of sustainable assessment practices to unsettle inequalities within higher education.
Student Academic Integrity in Online learning in higher education in the era of COVID-19
Authors: Augusta Carolyn , Henderson Robert D E
Published: July 2021

We examine strategies for reducing academic misconduct in online courses both when the instructor must move a course from in-person to online, and when an online course is developed intentionally. In the winter of 2020, courses that would not traditionally have been developed for web-based learning were retrofitted mid-term to accommodate restrictions introduced by the COVID-19 pandemic, which may have introduced additional challenges regarding assurance of academic integrity. Beyond discussing plagiarism, which is thought of as one of the most common types of academic dishonesty (Marques et al., 2019), we consider subscription-based digital resources which may enable cheating on a broader scale. We review the motivation behind many instances of academic dishonesty and suggest methods for mitigation. We emphasize the need for promoting honesty, not just preventing dishonesty. Although we focus our examples on large introductory-level quantitative courses, our strategies may be applied more broadly. In particular, we address the question: as an instructor, how can I prevent academic misconduct to the best of my ability in an online environment during a global pandemic?
Statistical comparison of typical Hungarian administrative public service processes using key performance indicators
Authors: Buics László , Süle Edit
Published: July 2021

This study aims to comparatively analyse the front office operations of two Hungarian gov-ernment windows, one located in a capital city district and the other in a county district centre, to examine the difference in the perceived service levels. First, through an international literature review, the study describes the background of the government window system and the importance of key performance indicators (KPIs). In addition, it demonstrates how KPIs can be measured in a public service context, regardless of the type and complexity of a given service. Second, the study provides a detailed statistical analysis and a comparison of the typical administrative public services related to waiting times, processing times, and lead times. Moreover, it offers an analogy of industrial service process management by presenting how the selected meth-ods and measures can be used to review processes related to an industrial, a manufacturing, or a public service, following a holistic management approach. The study contributes to the literature by using KPIs of the private sector and industry in public service processes and shows how these common KPIs can be measured in the public service context to provide valuable insights into service processes. Finally, it demonstrates the differences between the KPIs of the government windows to help legislators to increase the efficiency and effectiveness of services.
Image of Polyethnic Petersburg in Modern Media
Authors: Zavalishin A. Yu. , Kosturina N. Yu.
Published: July 2021

The paper presents the author’s vision of the meaning behind the terms: “ethnos”, “ethnicity”, “nation”, “nationality” and the links between them. It is argued that the concepts of “nation” and “nationality” have a sociopolitical connotation, while the notions of “ethnos” and “ethnicity” have a sociocultural one. It is determined that the contemporary native population of St. Petersburg is multinational, but not multiethnic, as the culture it perpetuates on a daily basis is not of their cultural origin, but is built on the traditional Russian culture, including its language, historical and cultural heritage of the ethnic groups of Russia. The authentic multi-ethnicity in St. Petersburg exists due to the current of ethnic migrants from the neighboring countries. A content analysis of the modern media sources indicates that the topic of migration is rarely discussed both in professional and amateur environments. The published materials are scarce, uninformative and are not done for the purpose of creating a multi-ethnic identity of St. Petersburg.

Remote Vascular Interventional Surgery Robotics: A Literature Review
Authors: Zhao Yang , Mei Ziyang , Mao Jingsong , Zhao Qingliang , Liu Gang , Wu Dezhi
Published: July 2021

Vascular interventional doctors are exposed to radiation hazards during surgery and endure high
work intensity. Remote vascular interventional surgery robotics is a hot research field, in which researchers
aim to not only protect the health of interventional doctors, but to also improve surgical accuracy and
efficiency. However, the current vascular interventional robots have numerous shortcomings, such as poor
haptic feedback, few compatible surgeries and instruments, and cumbersome maintenance and operational
procedures. Nevertheless, vascular interventional surgery combined with robotics provides more cutting?edge directions, such as Internet remote surgery combined with 5G network technology and the application
of artificial intelligence in surgical procedures. To summarize the developmental status and key technical
points of intravascular interventional surgical robotics research, we performed a systematic literature search
to retrieve original articles related to remote vascular interventional surgery robotics published up to
December 2020. This review, which includes 113 articles published in English, introduces the mechanical
and structural characteristics of various aspects of vascular interventional surgical robotics, discusses the
current key features of vascular interventional surgical robotics in force sensing, haptic feedback, and control
methods, and summarizes current frontiers in autonomous surgery, long-distance robotic telesurgery, and
magnetic resonance imaging (MRI)-compatible structures. On the basis of summarizing the current research
status of remote vascular interventional surgery robotics, we aim to propose a variety of prospects for future
robotic systems
Positioning Techniques in Indoor Environments Based on Stochastic Modeling of UWB Round Trip Time Measurements
Authors: Carbone Paolo
Published: July 2021

In this paper, a technique for modeling propagation of Ultra Wide Band (UWB) signals in indoor or outdoor environments is proposed, supporting the design of a positioning systems based on Round Trip Time (RTT) measurements and on a particle filter. By assuming that nonlinear pulses are transmitted in an Additive White Gaussian Noise Channel, and detected using a threshold based receiver, it is shown that RTT measurements may be affected by a non-Gaussian noise. RTT noise properties are analyzed, and the effects of non-Gaussian noise on the performance of a RTT based positioning system are investigated. To this aim, a classical Least Square, an extended Kalman Filter and a Particle Filter are compared when used to detect a slowly moving target in presence of the modeled noise. It is shown that, in a realistic indoor environment, the Particle Filter solution may be a competitive solution, at a price of increased computational complexity. Experimental verifications validate the presented approach.
Machine learning - based framework for construction delay mitigation
Authors: Sanni-Anibire Muizz O. , Zin Rosli M. , Olatunji Sunday O.
Published: July 2021

The construction industry, for many decades, has been underperforming in terms of the success of project delivery. Construction delays have become typical of many construction projects leading to lawsuits, project termination, and ultimately dissatisfied stakeholders. Experts have highlighted the lack of adoption of modern technologies as a cause of underproductivity. Nevertheless, the construction industry has an opportunity to tackle many of its woes through Construction 4.0, driven by enabling digital technologies such as machine learning. Consequently, this paper describes a framework based on the application of machine learning for delay mitigation in construction projects. The key areas identified for machine learning application include "cost estimation", "duration estimation", and "delay risk assessment". The developed framework is based on the CRISP-DM graphical framework. Relevant data were obtained to implement the framework in the three key areas identified, and satisfactory results were obtained. The machine learning methods considered include Multi Linear Regression Analysis, K-Nearest Neighbours, Artificial Neural Networks, Support Vector Machines, and Ensemble methods. Finally, interviews with professional experts were carried out to validate the developed framework in terms of its applicability, appropriateness, practicality, and reliability. The main contribution of this research is in its conceptualization and validation of a framework as a problem-solving strategy to mitigate construction delays. The study emphasized the cross-disciplinary campaign of the modern construction industry and the potential of machine learning in solving construction problems.
Improving construction safety with virtual-design construction technologies – a review
Authors: Afzal Muneeb , Shafiq Muhammad Tariq , Jassmi Hammad Al
Published: July 2021

The construction industry is prone to major safety hazards owing to the complex and onsite nature of construction projects. Hence, construction researchers have been pursuing concepts, methods, and tools using advancing technologies to improve construction safety management. Subsequently, the rapid digitization of construction work practices is providing opportunities to improve construction safety. Research has revealed that construction safety management practices can benefit from the applications of virtual design construction technologies (VDC), such as building information modeling (BIM), virtual reality (VR), augmented reality (AR), geographic information systems (GIS), and gaming technology. This study comprehensively reviews 191 research articles, published between 2010 and 2019, focusing on providing an overview of the implementation and application of VDC technologies for improving construction safety. The objective of this review is to critically collect and analyze applications of VDC technologies and present a holistic view of the features and functions of VDC technologies that can impact jobsite safety improvement in the construction industry. The review showed that VDC technologies can substantially improve construction safety. Emerging digital technologies, such as BIM, VR, AR, GIS, and gaming technologies can transform the traditional document-oriented safety procedures into digitalized safety practices allowing safety managers to visualize and analysis construction sites virtually to devise proactive safety measures and effective safety trainings. This study also highlights challenges such as research gaps regarding these digital tools that are currently impeding their widespread use in construction safety.

Published: July 2021

This study aimed to evaluate the effect of oil-heat treatment on the anatomical, physical, and chemical properties of the tropical fast-growing wood species as gmelina (Gmelinaarborea) and mindi (Melia azedarach) wood. Vessel lumen area and diameter in radial and tangential direction of both species increased with increasing temperature. The fiber lumen areas in both woods were remarkably decreased by oil-heat treatment, and the fiber wall area increased considerably with increasing temperature. Both woods tended to gain weight after heat treatment at 180°C and 200°C, and then lose weight after heat treatment at 220°C. The density of mindi increased greatly at 180°C and 200°C and slightly decreased at 220°C. The dimension of the specimens in tangential direction increased with heat treatment, but the rate decreased with increasing temperature. The relative crystallinity and crystallite width of the heat-treated woods were greater than those of the untreated wood. In the Fourier transform infrared analyses, the peaks from the carbohydrates were changed after oil-heat treatment, mainly due to the degradation of hemicellulose. Consequently, it was revealed that the heat treatment affected various properties of gmelina and mindi woods. Differing characteristics between the species were also noted.

Authors: Antov Petar , Savov Viktor , Neykov Nikolay , Krišťák Ľuboš
Published: July 2021

In this work, wet-process fibreboards (hardboards) were produced in the laboratory
using industrial wood fibres of the species European beech (Fagus sylvatica L.) and
Turkey oak (Quercus cerris L.) at the total volume of 40%, and white poplar (Populus alba L.) at 60% volume. The effects of hot pressing pressure (varied from 3.3 MPa to 5.3 MPa) and pressing time (from 255 s to 355 s) on the physical and mechanical properties of hardboards were investigated and optimal values of the parameters for fulfilling the European standard requirements were determined. It was concluded that hardboards with acceptable physical and mechanical properties may be produced from 60% poplar wood waste and residues, combined with 40% hardwood raw materials (beech and oak) by regulating the hot pressing regime only, i.e. pressure and pressing time. The following minimum parameters for producing hardboards from mixed hardwood tree species were determined: a pressure of 4.6 MPa and a pressing time of 280 s.

Published: July 2021

The influence of addition of deinked pulps with low and high brightness to bleached eucalyptus and pine kraft pulps on functional tissue paper properties was studied. Deinked pulps with low and high brightness had some different functional properties. Deinked pulp with high brightness has higher bulk, porosity, water absorption after immersion, initial water absorption, bulk softness as well as brightness. On the contrary, the difference in relative bonded area and porosity e between deinked pulps with low and high brightness was moderate. The mixed pulps laboratory pulp sheets from bleached eucalyptus kraft pulp or bleached pine kraft pulp with addition of 20, 40 and 80% of deinked pulp with low brightness or deinked pulp with high brightness were prepared. The addition of the deinked pulp with high or low brightness to bleached kraft pulp leads to increasing of bulk, bulk softness as well as high water absorption after immersion and initial water absorption. The tensile index rapidly decreased by the addition of deinked pulps with high brightness to bleached eucalyptus and pine kraft pulps. Similarly, the addition of deinked pulp with low brightness to bleached pine kraft pulp led to rapid decreasing of tensile index. On contrary, with the addition of deinked pulp with low brightness to eucalyptus kraft pulp, the decreasing of tensile index was less pronounced. Mixed pulp from bleached eucalyptus kraft pulp with a small content of deinked pulp with low brightness with functional properties suitable for production of tissue papers was found as optimal.

MATHEMATICAL EXPLANATION OF SUSTAINABLE POLITICAL DEVELOPMENT OF THE SOCIETY
Authors: Черкашин Александр Константинович
Published: July 2021

Обсуждается возможность математического объяснения современных социально-политических событий в Российской Федерации и за рубежом, что проявляют скрытые закономерности расслоения и изоляции общества на всех уровнях его организации. Формируются новые модели дистанционного взаимодействия - коммуникации разных социальных слоев, объединение их в комплексы сетей информационно-функциональных связей. Эти закономерности сквозным образом в разных масштабах описываются метатеоретическими моделями и методами расслоения с использованием универсальных математических уравнений, аксиоматической теории деятельности и устойчивого развития, раскрывающими этические, правовые и политические аспекты сосуществования. Содержательная интерпретация формального подхода основывается на идеях трансцендентальной аргументации И.Канта - автора морально-нравственного категорического императива, концепции правового государства и политической философии. Формулируется безусловная идея устойчивого мироустройства, которая берется за основу всякого общественного закона как выражения идеала, прообраза будущего, что становится основанием для предсказания прогрессивных форм политической деятельности.

The opportunity of a mathematical explanation of modern socio-political events in the Russian Federation and abroad is discussed. It reveals hidden patterns of stratification and isolation of society at all levels of its organization. New models of remote interaction are being formed: communication of different social strata, combining them into complexes of networks of information and functional connections. These laws are described in a through manner at different scales by meta-theoretical models and bundle methods using universal mathematical equations, axiomatic theory of activity and sustainable development, which combines the ethical, legal and political aspects of coexistence. The content interpretation of the formal approach is based on the ideas of the transcendental argumentation of I. Kant as the author of moral categorical imperative and the concept of the rule of law and political philosophy. An unconditional idea of a stable world order is formed, which is taken as social law expressing an ideal prototype of the future and the basis for predicting progressive forms of political activity.

Published: July 2021

На сегодняшний день применение ряда моделей диагностики состояния предприятия нецелесообразно в условиях российской экономики по следующим причинам. Во-первых, применение различных моделей приводит к противоречивым результатам. Во-вторых, прогнозная точность моделей значительно уменьшается при использовании для анализа финансового состояния данных за несколько лет до банкротства. В-третьих, зарубежные модели не учитывают специфику экономической ситуации и организацию предпринимательства в России, которые отличаются, в том числе, системами бухгалтерского учета и налогового законодательства, что находит отражение как в наборе факторов-признаков, так и в весовых коэффициентах при них. В-четвертых, в моделях используются данные за один год, и не учитываются изменения показателей в динамике за несколько лет. В-пятых, существующие модели используют в своем анализе ограниченный спектр показателей, определяющих ликвидность, платежеспособность, рентабельность и, как правило, являются расширенными или измененными западными моделями 60-80 гг. XX в. Круг факторов, определяющих риск потери степени устойчивости, заметно больше, это обусловливает необходимость совершенствования моделей его оценки за счет расширения его дополнительными параметрами.

To date, the use of a number of models for diagnosing the state of an enterprise is impractical in the conditions of the Russian economy for the following reasons. First, the use of different models leads to conflicting results. Secondly, the predictive accuracy of the models is significantly reduced when using data for the analysis of the financial condition of several years before bankruptcy. Thirdly, foreign models do not take into account the specifics of the economic situation and the organization of entrepreneurship in Russia, which differ, among other things, in the systems of accounting and tax legislation, which is reflected both in the set of factor-signs and in the weight coefficients for them. Fourth, the models use data for one year, and do not take into account changes in indicators over several years. Fifth, the existing models use in their analysis a limited range of indicators that determine liquidity, solvency, profitability and, as a rule, are extended or modified Western models of the 60-80s. XX century. The range of factors that determine the risk of losing the degree of stability is much larger, this necessitates the improvement of models for its assessment by expanding it with additional parameters.

Прогнозирование производственно-экономических показателей аграрного производства актуально для составления перспективных планов и программ по развитию агропромышленного комплекса на различных уровнях: регион, муниципальное образование, сельскохозяйственный товаропроизводитель. В статье описан разработанный авторами программный комплекс, позволяющий прогнозировать урожайность сельскохозяйственных культур, затраты труда на получение продукции, объемы производства, финансовые показатели на среднесрочную и долгосрочную перспективы. Для прогностических целей использованы функции роста с насыщением: асимптотическая и логистическая. Программный комплекс апробирован на данных муниципальных районов и сельскохозяйственных предприятий региона. С его помощью определяются значимые модели, позволяющие составлять прогнозы с различной заблаговременностью, а также оценивать прогностические значения с учетом различных условий деятельности сельскохозяйственных предприятий.

Forecasting production and economic indicators of agricultural production is relevant for drawing up long-term plans and programs for the development of the agro-industrial complex at various levels: a region, a municipality, an agricultural producer. This paper describes the created software package that allows predicting the yield of agricultural crops, labor costs for obtaining products, production volumes, financial indicators for the medium and long term. For prognostic purposes, the functions of growth with saturation were used: asymptotic and logistic. The software package has been tested on data from municipal districts and agricultural enterprises of the region. With its help, significant models are determined that make it possible to make forecasts with different lead times, as well as to evaluate prognostic values, taking into account different conditions of agricultural enterprises.

The tobacco industry has a long history. The use of tobacco products caused controversy among leading doctors, scientists and economists for a long time. A huge number of studies have revealed the undoubted harm of tobacco use on human health. Despite the adoption of laws in many countries that prohibit or restrict smoking, the tobacco industry is still one of the leading branches of the economy. Whereas the harm caused by tobacco products to the human body has been thoroughly studied, and the composition of cigarette smoke has been identified with an accuracy of 7,000 different chemical elements, the damage caused to nature has not yet been discovered. In this study, we will assess the impact of the tobacco industry on the environment. In order to do this, we will consider all stages of the existence of tobacco products: from the cultivation of tobacco leaves to direct consumption and subsequent disposal of cigarette butts. Each of the stages contains clear and threats to the environment. The study is based on the experience of China as one of the largest tobacco producers and consumers. China is a country experiencing serious environmental problems, but plans to reach the level of carbon neutrality by 2060. The result of our analysis will be a quantitative assessment of the harm (in particular, CO2 emissions) caused by the tobacco industry to the environment in China, as well as recommendations for reducing the calculated effect.
(RE)PENSANDO TERRA, CORPO E TEMPO

Published: July 2021

Este artigo apresenta algumas ferramentas analíticas para uma produção anti-branquidade, a partir de três eixos de reflexão: terra, corpo e tempo. No que diz respeito à terra, argumenta acerca da importância de considerar processos de remoção como banimento racial. Apresenta a ontologia combativa como concepção de corpo anti-branquidade. Por fim, apresenta o afrofuturismo como perspectiva de tempo confluente que reconhece a transfluência, nos termos de Bispo (2015).
UMA MODERNIDADE ALTERNATIVA?
Authors: Andrade Inácio de Carvalho Dias de
Published: July 2021

O artigo analisa a (re)produção da ideia de raça na urbanização de Lourenço Marques durante o período tardo-colonial. Na atual Maputo, seguidos projetos de urbanização buscaram dar materialidade a uma moderna nação ultramarina portuguesa ao mesmo tempo em que tentaram solucionar o problema da mão de obra autóctone. Assim, a capital moçambicana foi edificada a partir de diferentes percepções acerca de modernidade, de trabalho e de raça, que buscavam imprimir, ao cenário urbano laurentino, os grandes motes da colonização lusitana.  Assim, o celebrado movimento de arquitetura moderna de Moçambique nasceu em meio a um dilema: como projetar uma cidade moderna, humanista e igualitária no bojo do violento governo colonial português? Embora esse impasse não tenha sido necessariamente resolvido (e tenha sido muitas vezes ignorado), o legado da geração modernista em Lourenço Marques ainda é bastante perceptível nos edifícios e avenidas da capital e nos dão pista para compreender a produção da ideia de raça no império colonial português.

We have used B, V time-series photometry collected with the Large Binocular Telescope to undertake the first study of variable stars in the Milky Way ultra-faint dwarf (UFD) satellites Pisces II and Pegasus III. In Pisces II we have identified an RRab star, one confirmed and a candidate SX Phoenicis star, and a variable with uncertain classification. In Pegasus III we confirmed the variability of two sources: an RRab star and a variable with uncertain classification, similar to the case found in Pisces II. Using the intensity-averaged apparent magnitude of the bona fide RRab star in each galaxy, we estimate distance moduli of (m − M)0 = 21.22 ± 0.14 mag (d = 175 ± 11 kpc) and 21.21 ± 0.23 mag (d = 174 ± 18 kpc) for Pisces II and Pegasus III, respectively. Tests performed to disentangle the actual nature of variables with an uncertain classification led us to conclude that they most likely are bright, long-period, and very metal-poor RRab members of their respective hosts. This may indicate that Pisces II and Pegasus III contain a dominant old stellar population (t > 12 Gyr) with metallicity 〈[Fe/H]〉 − 1.8 dex along with, possibly, a minor, more metal-poor component, as supported by the V, B – V color–magnitude diagrams of the two UFDs and their spectroscopically confirmed members. The metallicity spread that we derived from our data sample is ≳0.4 dex in both systems. Lastly, we built isodensity contour maps that do not reveal any irregular shape, thus making the existence of a physical connection between these UFDs unlikely.

pairwise force calculations. To solve the post-million-body problem, it will be necessary to use approximate force solvers, such as tree codes. In this work, we adapt a tree-based, optimized Fast Multipole Method (FMM) to the collisional N-body problem. The use of a rotation-accelerated translation operator and an error-controlled cell opening criterion leads to a code that can be tuned to arbitrary accuracy. We demonstrate that our code, Taichi, can be as accurate as direct summation when N > 104. This opens up the possibility of performing large-N, star-by-star simulations of massive stellar clusters and would permit large parameter space studies that would require years with the current generation of direct summation codes. Using a series of tests and idealized models, we show that Taichi can accurately model collisional effects, such as dynamical friction and the core-collapse time of idealized clusters, producing results in strong agreement with benchmarks from other collisional codes such as NBODY6++GPU or PeTar. Parallelized using OpenMP and AVX, Taichi is demonstrated to be more efficient than other CPU-based direct N-body codes for simulating large systems. With future improvements to the handling of close encounters and binary evolution, we clearly demonstrate the potential of an optimized FMM for the modeling of collisional stellar systems, opening the door to accurate simulations of massive globular clusters, super star clusters, and even galactic nuclei.
