Authors: Dronov Olexii I. , Kovalska Inna O. , Horlach Andrii I. , Shchyhel Ivanna A. , Ivanets Tetiana Y.
Published: April 2023

The aim: To determine the role of the abdominal perfusion pressure level at the beginning of the disease in predicting the timing of infection of acute nec¬rotizing pancreatitis.
Materials and methods: A retrospective cross-sectional single-center study of 39 patients with acute severe pancreatitis (ASP) and pancreatic infection (PI) with measured and calculated minimal abdominal perfusion pressure (APP) in the first 48 hours of the disease. The existence of a correlation between the onset of PI and the level of intra-abdominal (IAP) and abdominal perfusion pressure was calculated and a single-factor mathematical model of linear regression was built.
Results: A negative strong correlation was found between IAP and the timing of PI onset, ρ=-0.818 (p<0.001), and a positive strong correlation was found between APP and the timing of PI onset, ρ=0.933 (p<0.001). The dependence of the outcome variable (PI term) on the APP value was revealed, adjusted coefficient of determination R²adj = 0.887 was corrected, F value 288.5, p<0.001, root mean square errors RSE = 1.31 (with 37 degrees of freedom). The value of the coefficient X1 was 0.47±0.0, p<0.001.
Conclusions: An increase in IAP in the first 48 hours of the desease in patients with ASP was, on average, accompanied by a reduction in the start of PI. A decrease in APP in the first 48 hours of the desease in patients with ASP was, on average, accompanied by a reduction in the start of PI. In the study sample, it was possible to predict the time of PI initiation by measuring the APP level in the first 48 hours of the disease with a margin of error for 1.3 days. It was found that with a decrease in the APP level, the time of the PI occurrence was reduced (p<0.001), on average, by 0.47±0.02 days for each mm Hg of APP.
Association of Secreted Frizzled-Related Protein 4 with Obesity and Type II Diabetes

Published: April 2023

Secreted frizzled-related protein 4 (SFRP4) is secreted protein family member similar to the sequence of frizzled receptors of wingless-related integration site (Wnt) signaling pathways which regulate various functions from fetal growth to adulthood. SFRPs are recognized as opponents of Wnt signaling and are thought to be affiliated with Wnts. Further research revealed their interaction with frizzled receptors and functional differences were transferred to these proteins, the power of Wnt signaling without flexibility. Also, SFRP4 is linked to many diseases including obesity, type 2 diabetes (T2D), and cancer. In addition, SFRP4 acts as a biomarker for the diagnosis of T2D and its expression is observed before the clinical diagnosis of T2D. This review is mainly focused on the role of SFRP4 in obesity and its role in β-cell failure that leads to T2D. SFRP4 acts on adipose tissue that causes increased production of adipokines which creates oxidative stress in the pancreas with low levels of antioxidant enzymes in pancreatic β-cells resulting in failure of insulin exocytosis. Inflammation caused by obesity is an important factor in the pathogenesis of insulin resistance and metabolic syndrome. Pro-inflammatory cytokines may induce insulin resistance in adipose tissue, bone tissue and liver by blocking the transmission of insulin signals. SFRP4 secretion is caused by interleukin 1-β (IL1-β).This review also highlights the molecular mechanisms by which SFRP4 leads to T2D. Understanding the cellular pathway and identifying SFRP4 may help to eliminate or reduce the chances of developing T2D.
Examining Teacher Candidates’ Pedagogical Practices and Stances Towards Translanguaging and Multimodality in Writing
Authors: Rajendram Shakina , Burton Jennifer , Wong Wales , Bale Jeff
Published: April 2023

This study examines pre-service teacher candidates’ (TCs) stances and use of translanguaging and multimodality to support K-12 multilingual learners’ writing. Data were drawn from a course on supporting multilingual learners in a teacher education program in Ontario. Data sources were responses to the Pedagogical Content Knowledge for Language- Inclusive Teaching (PeCK–LIT) Test, and TCs’ unit plans and lesson plans. Analytical codes were derived from the literature on translanguaging: monolingual and translanguaging stance, translanguaging as a scaffold and resource, teacher-directed and student-directed, intentional and spontaneous translanguaging, and supporting monomodality and multimodality. Findings demonstrate the use of translanguaging strategies such as multilingual word walls and online translation tools. However, there were constraints to TCs’ stances, such as allowing translanguaging as a temporary scaffold towards English-only instruction and approaching writing as a discrete rather than multimodal skill. The paper recommends ways TCs can be supported in developing a holistic understanding of translanguaging and multimodality.
Approaching the Concept of Multiliteracies: Multilingual Writing Competence as an Integrated Model
Authors: Usanova Irina , Schnoor Birger
Published: April 2023

In linguistically diverse contexts, language repertoires include various literacy skills in multiple languages across different modes of representation (multiliteracies), where multilingual writing can be conceptualized as a synthesized competence that includes all languages in a person’s repertoire and is continuously evolving. We respond to the call to operationalize existing theory on multilingual writing for empirical testing by conducting first- and second-order confirmatory factor analyses that explore whether and how students’ writing proficiency in different languages can be modelled as an integrated construct, to analyze multilingual writing’s dimensionality. We draw on a corpus of multilingual writing in secondary students (n = 965) in three different languages: the majority language (German), the heritage languages of migrants in Germany (Russian or Turkish), and the first foreign language (English). Based on competence data of a substantial sample of multilingual adolescents, the results provide an empirical approach to modelling multilingual writing competence in complex multilingual repertoires.
TSLP and asthma: fellow travelers
Authors: El-Qutob David , Letran Antonio
Published: April 2023

The incidence of asthma, a heterogeneous inflammatory disease affecting over 300 million people worldwide, continues to increase in developed countries. Human epithelial cells (ECs) express the alarmin-type cytokine thymic stromal lymphopoietin (TSLP) following tissue injury triggered by several environmental insults, which include allergens, smoke, pollutants, or other irritants. Furthermore, TSLP has an emerging but well-documented pathogenic role in asthma. TSLP has been called a “master switch” of allergic inflammation at the epithelial-dendritic cell (DC) interface, where it supports T helper 2 (Th2) inflammatory polarization and promotes the maintenance of Th2 memory responses. Therefore, targeting TSLP/TSLP-mediated signaling may represent an attractive therapeutic strategy for asthma. Several studies of anti-TSLP drugs are ongoing; the first-in-class anti-TSLP monoclonal antibody (mAb) tezepelumab, the immunoglobulin G1 antibody fragment CSJ117, or TSLP-traps [a combination of anti-interleukin-13 (anti-IL-13) and anti-TSLP mAbs] all represent promising new treatment approaches. This article reviews the characteristics of TSLP and discusses the treatment of severe asthma through TSLP-associated mechanisms.

The emergence of a new variant of the coronavirus, SARS-Cov-2, which causes the Corona Virus Disease (Covid-19) outbreak has really changed the world. First reported in Wuhan City, Hubei Province, China at the end of 2019, this virus has spread throughout the world. Apart from hitting the world economy, the Covid-19 pandemic has also changed the way humans interact. All over the world, people have changed their habits of work, worship, and social activities. This was done to reduce the risk of transmission of the massive new coronavirus. But the next question arises: when will conditions improve? when will this Covid-19 outbreak subside? To answer this question, this study seeks to model the spread of the new Corona Virus with a Dynamic Systems approach. In the modelling carried out, there are seven scenarios that describe the policies undertaken to mitigate the spread of Covid-19 which include WFH policies, office vacations, social distancing, implementation of PSBB, to PSBB relaxation. The resulting model is then validated with data from the Covid-19 Handling Acceleration Task Force which is released every day. Of the seven modelled scenarios, the fastest pandemic relief time is predicted to occur on September 25, 2020, as indicated by scenario 0 with a prediction of a total of 530,655 positive cases. The longest pandemic relief time is predicted to occur on July 17, 2021, with a prediction of a total of 269,115 positive cases.

Abstract— Currently the benefits of using information technology affect the human environment, one of which is organizational performance on campus, which has rooms for lectures, student activities and other parties. One of the problems faced in the university environment is the management of the room, when the room is being used or will be borrowed. Room management, which is still done manually, makes it difficult to borrow rooms and get information on the schedule for the use of the room used. Therefore we need a room management system that can make it easier to borrow according to the room you want to use, can schedule rooms outside the use of lectures according to what has been scheduled in the university environment. The purpose of this research is to create a website-based room management system on campus. In order to make it easier for related parties to help an organization so that they can provide information, management, and business processes that run in an organization. The methodology used in designing this software is the Rational Unified Process (RUP) with inception, elaboration, construction, and transition stages. The modeling used in software design is the Unified Modeling Language (UML). The results of the research that has been carried out is that a website-based room management system can borrow rooms, provide information regarding rooms whether they are being used or not, schedule room use outside of the use of lectures that have been scheduled in the campus environment.Keywords—Space, Information Systems, Rational Unified Process
THE LATE MAGDALENIAN IN POLAND — NEW DATA, NEW ISSUES
Authors: Połtowicz-Bobak M. , Bobak D.
Published: April 2023

New research on the settlement of the Magdalenian culture in the Polish lands has made it possible to discover new sites. These new sites come mainly from two regions: Sandomierska Upland, at the confluence of the two rivers Vistula and San, and in south-eastern Poland. In the latter region, the sites are associated with the valley of the San and its tributary, the Wisłok. The two regions are linked by a network of raw material links and also by their distribution along the San and at its confluence with the Vistula. The new discoveries in eastern Poland raise questions about both the boundaries of the Magdalenian and the relationship between Magdalenian and Epigravettian settlements.
FLINT RAW MATERIALS ON THE UPPER PALEOLITHIC SETTLEMENT ANETIVKA 2 IN THE GRANITE-STEPPE AREA OF THE SOUTHERN BUG REGION
Authors: Hlavenchuk A. V.
Published: April 2023

In modern research of the habitats of people of the late Paleolithic, mainly mineral raw materials and products were removed from the cultural layer, as they are the least susceptible to destruction over time. Archaeological site Anetivka 2, is located in the granite-steppe area of the Southern Bug, allows to present the width and intensity of use of mineral row matireals. During the excavations, about 2000 m2 of the site area was studied and a huge collection of stone and bone products, faunal finds was collected. The age of the site according to radiocarbon dating is 18—19 thousand years, which corresponds to the maximum of the last glaciation. The production complex of Anetivka 2 is characterized by the presence of a complete cycle of flint splitting: from split pebbles and nucleus to ready-made tools and hunting weapons. The flint industry of the site represents a spectacular feature of Epigravettian.

The industry of stone knapping and production of tools and hunting weapons at the site Anetivka 2 is based on the flint raw materials. The flint has a different quality and different degrees of patination. The flint raw materials that had been brought to the settlement of Anetivka 2 for use were of different sizes, primary and secondary occurrence, in the form of nodules, pebbles, tiles. The flint has different geological origin: from the layers of both the Upper Cretaceous and Sarmatian age. Widespread local flint (the so-called «Bakshalsky», such as Anetivka 13) is mainly in the form of nodule. To the recent, the outcrops of such flint can be observed near the confluence of the river Bakshala in the river Southern Bug. Flints, like other minerals from Anetivka 2, provides an example of the use of both local, nearby, easily accessible raw materials and stone raw materials that were delivered from afar.

The mineral raw materials of Anetivka 2 (including flint) have been studied for many years by a geologist and petrographer Victor F. Petrun (both in the field and laboratory — macroscopic and microscopic studies using a polarizing microscope). In 1991—1994, Victor F. Petrun, was a direct participant in the Anetian Paleolithic expedition, which explored the site of the Anetian region.
PALAEOLITHIC SITES NEAR THE BALAMUTIVKA VILLAGE
Authors: Kononenko O. M. , Ridush B. T. , Popiuk Ya. A.
Published: April 2023

The paper deals with the Palaeolithic materials found on the right bank of the Dniester River, in the vicinity of the Balamutivka Village, Chernivtsi Oblast, since the 1950s. Several sites, which have been recently discovered here, are published in detail for the first time. Particular attention is paid to the finds of Palaeolithic flint artefacts from caves located near the village.

Within the Balamutivka and further to the northeast, there are many Palaeolithic sites associated with Quaternary sediments of high (10—12) terraces. Because of the destruction of terraces and their slopes by landslides, the Palaeolithic flint artefacts lie on the surface there. An attribute analysis of the respective assemblages indicates a mixing of defining forms of different techno-complexes of the Middle — the end of the Upper Palaeolithic. In particular, the series includes convergent and sub-cross cores; carinated end-scraper, nosed end-scrapers; uni- and bidirectional sub-cylindrical cores, wide blades, combination tools — mostly burin + scraper; small-sized cores with one or two platforms, sub-cylindrical and narrow working surface, from which thin bladelet and microblade were knapped; microliths (including «Dufour», counter-retouch backing microliths), a Lacan-type burin (?).

In the caves, the knapped flints also did not occur in situ but got there from the surface of the terraces together with the loose terrace sediments due to water erosion and landslides. The caves are not suitable for habitation by humans or large predators because of their small size and hydrogeological regime (periodic flooding).

The area of Balamutivka Village is interesting and promising for further investigation of the Palaeolithic of the Middle Dniester region. The typological diversity of the finds from the studied locations evidences the presence of multilayer sites.
Dissociation and integration of outcome and state uncertainty signals in cognitive control
Authors: Alexander William H. , Deraeve James , Vassena Eliana
Published: April 2023

Signals related to uncertainty are frequently observed in regions of the cognitive control network, including anterior cingulate/medial prefrontal cortex (ACC/mPFC), dorsolateral prefrontal cortex (dlPFC), and anterior insular cortex. Uncertainty generally refers to conditions in which decision variables may assume multiple possible values and can arise at multiple points in the perception-action cycle, including sensory input, inferred states of the environment, and the consequences of actions. These sources of uncertainty are frequently correlated: noisy input can lead to unreliable estimates of the state of the environment, with consequential influences on action selection. Given this correlation amongst various sources of uncertainty, dissociating the neural structures underlying their estimation presents an ongoing issue: a region associated with uncertainty related to outcomes may estimate outcome uncertainty itself, or it may reflect a cascade effect of state uncertainty on outcome estimates. In this study, we derive signals of state and outcome uncertainty from mathematical models of risk and observe regions in the cognitive control network whose activity is best explained by signals related to state uncertainty (anterior insula), outcome uncertainty (dlPFC), as well as regions that appear to integrate the two (ACC/mPFC).
Specific absorption rate of randomly oriented magnetic nanoparticles in a static magnetic field
Authors: Rytov Ruslan Alekseevich , Usov Nikolai Aleksandrovich
Published: April 2023

Numerical simulations using the stochastic Landau–Lifshitz equation are performed to study magnetization dynamics of dilute assemblies of iron oxide nanoparticles exposed to an alternating (ac) magnetic field with an amplitude Hac = 200 Oe and a frequency f = 300 kHz and a static (dc) magnetic field in the range Hdc = 0–800 Oe. The specific absorption rate (SAR) of the assemblies is calculated depending on the angle between the directions of the ac and dc magnetic fields. For the case of an inhomogeneous dc magnetic field created by two opposite magnetic fluxes, the spatial distribution of the SAR in the vicinity of the field-free point is obtained for assemblies with different nanoparticle size distributions. The results obtained seem to be helpful for the development of a promising joint application of magnetic nanoparticle imaging and magnetic hyperthermia.

Published: April 2023

A protocol for the mechanochemical synthesis of copper(I)/N-heterocyclic carbene complexes using cheap and readily available K3PO4 as base has been developed. This method employing a ball mill is amenable to typical simple copper(I)/NHC complexes but also to a sophisticated copper(I)/N-heterocyclic carbene complex bearing a guanidine moiety. In this way, the present approach circumvents commonly employed silver(I) complexes which are associated with significant and undesired waste formation and the excessive use of solvents. The resulting bifunctional catalyst has been shown to be active in a variety of reduction/hydrogenation transformations employing dihydrogen as terminal reducing agent.

Published: April 2023

Разработка стратегий обеспечения ветеринарной безопасности на макро- и микроуровнях управления аграрной отраслью требует сбора достоверной и верифицируемой статистики заболеваемости, смертности по каждой болезни и виду животных. Это особенно важно для новых экзотических заболеваний, ранее не наблюдаемых на территории Республики Казахстан, по которым отсутствует местная статистика и достоверные результаты наблюдений.
В последнее время в связи с возросшими рисками глобализации и быстрого распространения особо опасных инфекций необходимо также учитывать угрозы и потенциальный ущерб от распространения зоонозных инфекций. Данный ущерб может значительно превышать прямой ущерб для сельскохозяйственного производства, пищевой и перерабатывающей отраслей. Это может приводить к росту социально-экономической напряженности и разрыву межрегиональных и международных связей. В связи с этим остро возникает необходимость развития системы мониторинга, оценки рисков, экономической оценки эффективности ветеринарных стратегий, в том числе по экзотическим и особо опасным болезням животных. Однако, для ряда экзотических и новых для Казахстана заболеваний, а также новых пород скота, ввозимых в Казахстан, данные по заболеваемости, смертности, влиянию на продуктивность в условиях Казахстана отсутствуют. Цель статьи состоит в определении основных методов экономической оценки эффективности ветеринарных стратегий, в том числе по экзотическим и особо опасным болезням животных. Для экономической оценки эффективности определены основные элементы расчётов, составляющие оценку экономической эффективности и являющиеся обязательными.

Научная статья подготовлена по результататам исследований, которые были выполнены в рамках проекта «Органическое производство картофеля и столовых корнеплодов (морковь, свекла) на основе использования адаптивно-экологичных сортов и биологизации агротехнологии культур в условиях юго-востока Казахстана». Исследования проведены по общепринятым в овощеводстве и агрохимии методикам. В условиях темно-каштановых почв предгорной зоны юго-востока Казахстана изучена эффективность новых видов органических удобрений и биопрепаратов на культуре картофеля. Оценивалось значение различных биоорганических удобрений в производстве органического картофеля.  В полевых опытах с картофелем выявлено действие органических удобрений, биоудобрений и биостимуляторов, производимых в Казахстане и зарубежных странах, на урожайность и качество клубней. В научной статье приведены экспериментальные данные за 2021-2022 гг. Установлено, что исследованные биоудобрения оказывают положительное влияние на ростовые процессы растений. Отмечено интенсивное развитие и формирование мощной биомассы картофельных растений. Наблюдалось улучшение качества продукции за счет снижения содержания нитратов. Биоорганические удобрения и биопрепараты повышали урожайность картофеля на 12,50-88,09% (2021 г.) и на 17,39-87,50% (2022 г.). Содержание нитратов в клубнях картофеля заметно колебалось в зависимости от видов применяемых удобрений. Минимальные уровни нитратов (60-84 мг/кг) отмечены в урожаях, выращенных с применением новых биоудобрений - StresStop, WORМiс, MEGAVit и BioZZ. Наименьшее содержание нитратов в картофеле (49 мг/кг) по опыту было на варианте, где применялось 100%-органическое удобрение Терра Сорб фолиар в норме 3 л/га (3-кратно).

Географиялық ақпараттық жүйелер гидрологияда су ресурстарын есептеу және бағалау үшін, су объектілерінің гидрологиялық режимін зерттеу мақсатында кеңірек қолданылуда. Деректерді жинау, өңдеу және интерпретациялау, гидрологиялық желілерді жобалау және географиялық ақпараттық жүйелері (ГАЖ) технологиясы мен дербес компьютерлерді кеңінен қолдану арқылы шешім қабылдау ұсыныстарын дайындаудың көптеген мәселелерін гидрологиялық тәжірибеде осы уақытқа дейін шешілгеннен жедел және тиімдірек шешуге болады. ГАЖ технологиясының су объектілерін гидрографиялық сипаттамаларымен, гидрологиялық бекеттерімен және өлшеу деректерімен бірге цифрлық немесе қағаз карталарда жедел ұсыну мүмкіндігі болып жатқан процестердің егжей-тегжейлі бейнесін алу үшін бақылау материалдарын автоматтандырылған кешенді талдау мен түсіндіруді жүргізуге мүмкіндік береді.
Бұл жұмыста Алматы облысының өзен бассейндерінде әртүрлі гидрологиялық мәселелерді шешу үшін ГАЖ-ды қолданудың әдістемелік тәсілдері ұсынылған. Сандық карталар таңдалған өзендердің қажетті физикалық-географиялық сипаттамаларын анықтады, олар бұрын жарияланған мәліметтермен салыстырылды. Зерттелетін өзендердің су жинау шекаралары нақтыланды.  Бассейндердің пішіні мен орналасуына байланысты сызықтық және аумақтық объектілерді дәл өлшеу үшін картографиялық проекцияларды таңдау принципі ұсынылды. ГАЖ технологиясын қолданып, картометриялық жұмыстарды орындаудың ұсынылған әдістемелік тәсілдері уақыт шығындарын едәуір қысқартуға және өлшеу нәтижелерінің дәлдігін арттыруға мүмкіндік берді.

Бұл жұмыстың зерттеу пәні Шелек өзенінің қазіргі жағдайы болып табылады. Зерттеу әдістері - бақылау деректерін жүйелеу және оларды статистикалық өңдеу, гидрологиялық есептеу. Жалпы, мақалада гидрологиялық бақылау пункттері ретінде Шелек өзенінде орналасқан 2 гидрологиялық бекет қарастырылды: Малыбай ауылы тұстамасындағы және Бартоғай су қоймасындағы. Шелек өзенінің ағынының ең ұзақ бақылау кезеңі Малыбай ауылы тұстамасындағы бекет бойынша 48 жылды (1956-2018 жж.) құрады. Осы мәліметтер бойынша Шелек өзенінің және Бартоғай су қоймасының гидрологиялық сипаттамаларын анықтау есептеулері жүргізілді. Өзеннің жылдық ағынының климаттық факторлары мен есептік сипаттамалары талданды. Жылдық ағынның нормасын және статистикалық параметрлерін есептеу үшін қолда бар бақылаулар қатары пайдаланылды, бұл негізінен 48 жылды құрады. Бартоғай су қоймасының табиғи су ресурстарының ортажылдық су мөлшері 971,04 млн.м3 құрады, шаруашылық-тұрмыстық, суғару қажеттіліктері үшін вегетациялық кезеңде оны кеңінен пайдалану мен өзен ағынын маусымдық реттеуге арналған.
Қарастырылып отырған бассейннің жалпы табиғи жағдайлардың алуан түрлілігі, орографиясының күрделілігі жыл ішінде өзеннің қоректенуі мен су режимінде айтарлықтай айырмашылықтардың болуын дәлелдейді. Ағынның негізгі үлесі көктем-жаз кезеңінде (наурыз-қазан) ағып өтеді және қар, мұздықтармен қоректенуді қамтамасыз етеді. Қарастырылып отырған аумақ гидрологиялық жағдайларға сәйкес таулы - ағынның қалыптасу аймағына және жазық – ағынның жоғалу және таралу аймағына бөлінген.

“PARENTESCO” ENTRE CONVENTOS
Authors: Guzzo Ana Maria Moraes , Travassos Bastos José Claudio
Published: April 2023

Este artigo é parte de minha tese defendida em agosto de 2020, no Programa de Pós-Graduação em Arquitetura - UFRJ, escrito em parceria com o arquiteto José Cláudio Travassos Bastos. Tem como objetivo discutir a unidade estilística conferida, por Germain Bazin, na década de 1950, aos conventos franciscanos do Nordeste brasileiro, edificados durante o período colonial. Para isso, foram desenvolvidas a revisão bibliográfica e documental, e estudos de caso com a análise comparativa de dois desses conventos da Ordem em questão: Convento de Santo Antônio (ou de São Francisco) de Paraguaçu – no município de Cachoeira; e Convento de Santo Antônio – em Cairu, ambos no estado da Bahia. Suas fachadas refletem semelhanças, e seus frontispícios remetem a um traçado de igual composição arquitetônica, embora possuam plantas distintas. Inúmeros e renomados estudiosos escreveram sobre esses conventos, mas a lacuna documental não auxiliou na identificação dos autores de seus projetos, e as datas de suas origens não são claras na bibliografia encontrada. Teorias foram lançadas sobre as construções dos conventos franciscanos, porém sem comprovação. Dessa forma, não foi possível determinar o “parentesco” entre as edificações estudadas, contudo, visivelmente observável. Assim, as conclusões dificilmente poderão ser finalizadas, mas os questionamentos deixam caminhos abertos para novas pesquisas.

O aumento da complexidade nos projetos de Engenharia trouxe a necessidade do uso de novos métodos de ensino de projetos nos cursos de Engenharia Civil. Com o desenvolvimento tecnológico e a evolução das formas de representação e estudo de projetos de Engenharia, tornou-se possível o emprego de novas ferramentas para visualização de projetos, dentre as quais, a Realidade Aumentada (RA). Esse estudo teve como objetivo realizar uma revisão sistemática da literatura sobre uso da RA como ferramenta para auxiliar o ensino de projeto, no curso de Engenharia Civil. A identificação dos artigos foi realizada em oito bases de dados, resultando em 1.300 artigos. Após a aplicação dos critérios de elegibilidade, 14 artigos foram incluídos para o estudo. A pesquisa evidenciou que apesar do uso da RA possuir grande potencial de impacto no ensino de projeto de Engenharia Civil, essa tecnologia ainda é pouco utilizada em sala de aula, necessitando aprimoramento de softwares e equipamentos. Ademais, a presente revisão sistemática indica possibilidades de uso e limitações da RA, tornando-se uma base para auxiliar a estruturar futuras pesquisas aplicadas na área.
Pricing two-asset rainbow options with the fast Fourier transform
Authors: Levendis Alexis , Maré Eben
Published: April 2023

In this paper, we present a numerical method based on the fast Fourier transform (FFT) to price call options on the minimum of two assets, otherwise known as two-asset rainbow options. We consider two stochastic processes for the underlying assets: two-factor geometric Brownian motion and three-factor stochastic volatility. We show that the FFT can achieve a certain level of convergence by carefully choosing the number of terms and truncation width in the FFT algorithm. Furthermore, the FFT converges at an exponential rate and the pricing results are closely aligned with the results obtained from a Monte Carlo simulation for complex models that incorporate stochastic volatility.

Penelitian ini membahas tentang penetapan garis keturunan/istbat an-nasab dengan menggunakan tes DNA, adanya perkembangan teknologi dengan tes DNA pada zaman moderen sering sekali digunakan sebagai sarana penetapan kecocokan garis keturunan seseorang. Agama Islam sangat perhatian dengan urusan tersebut, dalam hal ini agama Islam menjelaskan aturan-aturannya guna menjaga garis keturunan setiap pemeluknya. Dengan terjaga garis keturunan secara syari’at Islam yang benar, maka akan membawa kehidupan yang harmonis dalam keluarga yang menjadikan ajaran Islam sebagai pedoman hidupnya.
Penelitian ini dimaksudkan untuk menjawab permasalahan penetapan garis keturunan/istbat an-nasab dalam agama Islam dan perspektif Mazhab Imam Syafi’i ra terhadap penetapan hukum nasab/istbat an-nasab dengan tes DNA.
Tujuan penelitian ini mengetahui perihal yang telah ditetapkan agama Islam dalam garis keturunan seseorang dan perspektif Mazhab Imam Syafi’i ra terhadap penetapan garis keturunan/istbat an-nasab dengan menggunakan tes DNA.
Hasil penelitian ini adalah: (1) Cara penetapan garis keturunan dalam agama Islam melalui 4 proses penetapan yaitu: melihat kepada durasi kehamilan dari waktu pernikahan, pengakuan dari salah satu pihak, adanya persaksian dari keluarga dan menguji kecocokan hubungan keturunan dengan menggunakan jasa seorang dukun nasab yang disebut qaif. (2) Perspektif Mazhab Imam syafi’i ra terhadap hukum penetapan garis keturanan dengan tes DNA, dipandang sah dan diperbolehkan sebab adanyaa kemiripan dengan sistem penetapan dengan qiyafah, maka dalam hal ini diqiyaskan dalam proses tes DNA.
