Novel nectar robbing negatively affects reproduction in Digitalis purpurea
Authors: Mackin Christopher , Goulson Dave , Castellanos Maria Clara
Published: May 2021

With many plant-pollinator interactions undergoing change, we require a
better understanding of how the addition of new interacting partners,
such as antagonists, can affect plant reproduction. One such group of
antagonistic floral visitors, nectar robbers, can deplete plants of
nectar rewards without contributing to pollination. The addition of
nectar robbing to the floral visitor assemblage could therefore have
costs to the plant´s reproductive output. We focus on a recent plant
colonist, Digitalis purpurea, a plant that in its native range is rarely
robbed, but experiences intense nectar robbing in areas it has been
introduced to. Here, we test the costs to reproduction following
experimental nectar robbing. To identify any changes in the behaviour of
the principal pollinators in response to nectar robbing, we measured
visitation rates, visit duration, proportion of flowers visited and rate
of rejection of inflorescences. To find the effects of robbing on
fitness, we used proxies for female and male components of reproductive
output, by measuring the seeds produced per fruit and the pollen export
respectively. Nectar robbing significantly reduced the rate of
visitation and lengths of visits by bumblebees. Additionally, bumblebees
visited a lower proportion of flowers on an inflorescence that had
robbed flowers. We found that flowers in the robbed treatment produced
significantly fewer seeds per fruit on average but did not export fewer
pollen grains. Our finding that robbing leads to reduced seed production
could be due to fewer and shorter visits to flowers leading to less
effective pollination. We discuss the potential consequences of new
pollinator environments, such as exposure to nectar robbing, for plant
reproduction.

Published: May 2021

A 40-year-old woman underwent an atrial septal defect closure with
juxtaposition of the atrial appendages without communication between
both appendages 4 years before presentation. She recently experienced
desaturation on exercise, and right-to-left shunt coming from the
residual communication between both appendages was found. The residual
communication was closed from the right to the left atrium. Herein, we
report a rare case of juxtaposition of the atrial appendages with
residual communication between them after an atrial septal defect
closure.
Detecting non-random mating or selection in natural populations using multi-locus gene families
Authors: O'Reilly Gabe , Manlik Oliver , Vardeh Sandra , Sinclair Jennifer , Lawler Zachary , Sherwin William
Published: May 2021

New sequencing technologies have opened the door to many new research
opportunities, but these advances in data collection are not always
compatible with some important methods for data analysis. Fis has been a
staple calculation in the field of population genetics. Fis can be used
to measure either a departure from random mating, or measure underlying
selective pressures for or against heterozygote genotypes. However, when
using Next Generation Sequencing (NGS) technology on multi-locus gene
families it is often impossible to discern which allelic variants are
present at each locus. Some important multi-locus gene families are: the
major histocompatibility complex (MHC) in animals; homeobox genes in
fungi; or the self-incompatibility genes in plants. This in turn makes
it impossible to calculate either locus-specific expected
heterozygosity, or observed heterozygosity, both of which are required
to calculate Fis. Without the ability to calculate Fis from NGS of
multi-locus gene families, we need a new multi-locus measure that will
allow us to detect the underlining mating, and selective patterns
present in such multi-locus genes. This paper provides such a novel
multi-locus measure, called 1His. We demonstrate the accuracy of the
1His equation using simulated data, and two datasets taken from natural
populations of dolphins and penguins. The introduction of this new
measure is particularly important because of the great interest in
mating patterns and selection of multi-locus gene families, such as MHC.
Concentration in Asia’s Cross-Border Banking: Determinants and Impacts
Authors: Ana Kristel Lapid , Mercado Jr Rogelio , Rosenkranz Peter
Published: May 2021

Regional banking systems in Asia and the Pacific are not only increasingly integrated but also tend to be concentrated to a few counterparties only, exposing the region to financial risk and policy spillovers. This study assesses the determinants and impacts of the region’s cross-border banking concentration. It constructs and analyzes cross-border bank concentration measures for 47 economies in Asia and the Pacific from 2000 to 2019. Results suggest that higher capital account, trade openness, and per capita income are significantly associated with lower cross-border bank concentration. Moreover, elevated cross-border bank concentration tends to lower domestic credit growth and nonperforming loans.
Multidisciplinary approach in treatment of spacing: orthodontic treatment and partial veneers using the injectable composite resin technique
Authors: Ljubicic Milos , Zivkovic Marija
Published: May 2021

Introduction. Patients with orthodontic diagnosis of spacing most often
require a multidisciplinary approach, which includes orthodontic and
following restorative treatment to enhance the esthetic outcome. The aim of
this case report is to present management of spacing in the anterior region
by orthodontic treatment followed by partial veneers using the injectable
composite resin technique. Case report. In this case, leveling and alignment
of dental arches and stable occlusion was achieved during orthodontic
treatment, with the correction of upper and lower incisor inclination and
closing the diastemas. Intraoral and extraoral esthetic parameters were
evaluated on the photographs, and partial veneers on lateral incisors and
canines were designed for the wax-up model. In the injectable composite
resin technique, the silicone index was used to transfer the wax-up to
composite restorations. The highly filled injectable composite resin was
injected through the silicone index and light-cured. The restoration
required only gentle polishing due to the great precision of the index.
Discussion. Post-orthodontic recontouring in the anterior region is mostly
done by direct composite restorations because they are cost-effective,
minimally invasive, and the procedure is relatively simple. The injectable
resin composite technique can be a solution for the same indication since it
is less technique sensitive and gives predictable and great esthetic
results, mostly without tooth preparation. Conclusion. Management of
anterior spacing in adult patients requires a comprehensive approach for
optimal esthetic and functional results. In this case, orthodontic treatment
was followed by partial veneers on lateral incisors and canines, using the
injectable composite resin technique as a simple and predictable solution
for minor restorative interventions to solve morphological tooth
abnormalities in the esthetic smile zone.

Published: May 2021

Introduction. Determining the cause of shoulder pain is usually a challenge as many problems, such as rheumatoid arthritis, osteoarthritis, osteonecrosis, rotator cuff arthropathy, traumatic arthritis, fractures, conditions of cervical vertebra, and neo-plasms, can produce similar symptoms. The diagnosis is usually regarded as incidental, however, chronic lymphocytic leukemia (CLL) diagnosis by the histopathological evaluation performed on lymph nodes excised during a shoulder procedure has not been reported in the literature, to the best of our knowledge. We present a CLL-small lymphocytic lymphoma (SLL) case diagnosed incidentally during reverse shoulder arthroplasty. Case report. A 69-year-old female with a history of left proximal humerus fracture a year prior was presented to our outpatient clinic with left shoulder pain. A proximal humerus non-union was revealed radiographically. The patient underwent reverse shoulder arthroplasty. During surgery, a 2.5 ? 1.5 ? 1 cm sized lymph node was observed near the left cephalic vein. The lymph node biopsy result was reported to be CLL-SLL. The patient had no early postoperative complications and was dis-charged two days after. At her final evaluation, she was free of orthopedic complaints and was consulted with the hematology department to receive CLL-SLL treatment. Conclusion. Elderly patients presenting with non-union should be questioned for vague symptoms; lymph nodes surrounding the non-union site should be examined thoroughly. Any suspicious lymphadenopathy encountered during orthopedic surgery should be excised and sent for pathological evaluation

Published: May 2021

Background/Aim. Among the various factors that can influence continued postoperative back pain and/or leg pain, and functional disability after lumbar microdiscectomy are gender, depression, and pessimism. The aim of this study was to determine the correlations between these factors. Methods. The research was conducted after microdiscectomy on 198 patients (95 men and 103 women), with a mean age of 50.20 ? 10.26 years. The following questionnaires were used for examinations: for assessment of pain and its intensity and character ? PainDETECT Test; for functional disability ? Oswestry Low Back Pain Disability Questionnaire; for the presence and degree of depression ? Beck Depression Inventory-II; and questionnaire for the assessment of personal expectations (pessimistic/optimistic) about the treatment results. These assessments were carried out after microdiscectomy ? just before rehabilitation treatment, one month later, and then 3 and 6 months after a microdiscectomy. Results. Depression (p < 0.01) and pessimism (p < 0.01) had significant negative influences on the pain and functional disability. The subjective sensation of pain was significantly higher in women than in men (p < 0.01), while men had a greater degree of functional disability (p < 0.01) than women. Conclusion. Pain and functional disability of the patients after lumbar microdiscectomy are significantly interconnected with gender, depression, and pessimism. The sensation of pain was higher in women, while men had a greater degree of functional disability. Globally, the intensity of pain and functional disability were significantly greater in patients with a higher degree of depression and pessimism, and, by registering mentioned factors, it is possible to predict the postoperative results.

Published: May 2021

Objective:
To examine if the association between higher A1c and risk of CVD among adults
with and without diabetes is modified by racial residential segregation.

Design/Methods: The study used a
case-cohort design, which included a
random sample of 2,136 participants at baseline and 1,248 participants with incident CVD [i.e., stroke,
coronary heart disease (CHD), fatal CHD during 7-year follow-up] selected from
30,239 REGARDS participants originally assessed between 2003-2007. The relationship of A1c with incident CVD,
stratified by baseline diabetes status, was assessed using Cox proportional
hazards models adjusting for demographics, CVD risk factors, and socioeconomic
status. Effect modification by census tract-level residential segregation
indices (dissimilarity, interaction, isolation) was assessed using interaction
terms.

Results: The mean age of participants
in the random sample was 64.2 years, with 44% African American, 59% female, and
19% with diabetes. In multivariable models, A1c was not associated with CVD
risk among those without diabetes [HR per 1% (11
mmol/mol) increase = 0.94 (95% CI: 0.76 – 1.16)]. However, A1c was
associated with an increased risk of CVD [HR per 1% increase = 1.23 (95% CI: 1.08
– 1.40)] among those with diabetes. This A1c-CVD
association was modified by the dissimilarity (p <0.001) and interaction (p
= 0.001) indices. The risk of CVD was increased at A1c levels between 7% and 9%
(53 – 75mmol/mol) for those in areas with higher residential segregation (i.e.,
lower interaction index). In race-stratified analyses, there was a more
pronounced modifying effect of residential segregation among African American
participants with diabetes.

Conclusions:
Higher A1c was associated with
increased CVD risk among individuals with diabetes and this relationship was more pronounced at higher levels
of residential segregation among African American adults. Additional research on
how structural determinants like segregation may modify health effects is
needed.

Published: May 2021

This randomised,
double-masked, placebo-controlled trial (ACTRN12618000705280) evaluated the
effects of oral omega-3 fatty acid supplementation on peripheral nerves in type
1 diabetes. Participants with type 1 diabetes were assigned (1:1) to omega-3
(fish oil; 1800 mg/day) or placebo (olive oil; 600 mg/day) supplements for
180 days. Primary outcome was change from baseline in central corneal nerve
fibre length (CNFL) at day 180. Secondary outcomes included change in other corneal
nerve parameters, corneal sensitivity, peripheral small and large nerve fibre
function, and ocular surface measures. Efficacy was analysed following
intention-to-treat. Safety assessments included diabetic retinopathy grade and
adverse events.

Between July 2017 and
September 2019, 43 participants received omega-3 (n=21) or placebo (n=22)
supplements. All participants, except for two assigned to placebo, completed
the trial. At day 180, the estimated increase in CNFL in the omega-3 group,
compared to placebo, was 2.70 mm/mm2 (95%CI: 1.64-3.75). The Omega-3
Index increased relative to placebo (3.3%; 95%CI: 2.4-4.2). There were no
differences in most small or large nerve fibre functional parameters. Adverse
events were similar between groups.

In conclusion, this
randomised controlled trial found that long-chain omega-3 supplements impart
corneal neuroregenerative effects in type 1 diabetes, indicating a role in
modulating peripheral nerve health.

Bu çalışmada, bir enerji dağıtım sisteminin, başlangıçtaki yatırım giderlerinin, güç kayıplarının, zaman içerisinde olacak bakım-onarım giderlerinin ve sistemin maddi getirisinin dahil edildiği, çeşitli kapasitede güç gereksinimi ve şebeke uzunlukları için maliyet analizi gerçekleştirilmiştir. Kazancın en yüksek durumda olabilmesi için yeterli sayıda ve gereklilikte özdeş transformatörün sayıca miktarı incelenmiştir. Bunun için, en yüksek kazanç ve en kısa amortisman süresi dikkate alınmıştır. Küçük kesitli kablo olarak Swallow, büyük kesitli kablo olarak Hawk türü kablolar kullanılmıştır. Kalın kesin kesitli kabloların enerji kaybını önlemek için etkili olduğu, ancak gerçekte çok büyük maliyetin transformatörün kapasitesine bağlı olarak kendisinin neden olduğu gösterilmiştir. İdeal sayıda transformatörün tespiti için tek başına en yüksek kazancı ya da en kısa amortisman süresini almak yerine bu ikisinin birbirine en yüksek oranının ele alınmasıyla çok amaçlı bir optimizasyon problemi çözülmektedir.
Black Mountain: The politicisation of a pilgrimage site in western India
Authors:   , Whitby-Coles Charlotte
Published: May 2021

A once unremarkable site of multi-faith pilgrimage to a Sufi Saint has been transformed and its local history rewritten - this thesis presents a case study of research undertaken around the pilgrimage site of Kalo Dungar or Black Mountain, which is situated in the Rann of Kutch, Gujarat, India. It is based on traditional anthropological participant-observation fieldwork, as well as on library and archival research. The research is presented in the methodological framework of ‘ethnography as methodology’; this has enabled the researcher to present a linear journey reflecting the research process. A key element of this presentation, as well as the text of this doctoral thesis, is a film (DVD), Black Mountain. Both text and film suggest that the pilgrimage site of Kalo Dungar provides a micro-example of current issues in India today by highlighting the development of politically motivated religious orthodoxy across India; and that the nature of Kalo Dungar has been altered due to Hindu right-wing religio-political interests and actions, as is vividly demonstrated in the film. It is argued, by using theoretical insights gained by critically examining the cyclical process of syncretism and anti-syncretism, that this trend is aiding the slow break-down of communal harmony and of syncretic and pluralistic practices.

Improvement of Hardness of Hydroxyapatite by the Addition of Silica from Tin Tailings
Authors: Afriani Fitri , J Evi , Zaitun Zaitun , Tiandho Yuant
Published: May 2021

The application of bone scaffolding in bone therapy is an alternative solution developed in bone tissue engineering technology to avoid bone donors' scarcity. The main requirement for a material that can be used as a scaffold is that it is biocompatible. Hydroxyapatite is a calcium phosphate ceramic that is often used as the primary material for scaffolding because it has good biocompatibility properties. However, like most ceramics, hydroxyapatite has low mechanical properties. In this study, we synthesized hydroxyapatite from cockleshell waste. To improve hydroxyapatite's mechanical properties (hardness), we added silica from tin tailings to hydroxyapatite. Through the analysis of the x-ray diffraction (XRD) pattern, it was found that hydroxyapatite was successfully synthesized from cockleshell using the co-precipitation method. Analysis of the diffraction pattern of tin tailings also shows that most of the crystals comprising tin tailings sand are silica in the ?-quartz phase. The addition of silica to hydroxyapatite followed by compaction and sintering at a temperature of 800 ? did not produce a new crystal phase. The addition still has a diffraction pattern consisting of a combined XRD pattern of hydroxyapatite and silica. Based on the hardness test using the Vickers hardness method, it is known that the addition of silica can increase the hardness of hydroxyapatite.

West Sumatra is one of a geothermal potential in Indonesia because of interaction between Eurasian and Indo-Australian tectonic. The existence of volcanoes produces geothermal potential with lithology andesite, tuff, and lapilli lava in the Marapi Mountain complex, which elongated at NW-SE direction as a result of NE-SW subduction. The remote sensing method specifically with Composite Band 567 and Lineament Density Analysis (LDA) found anomaly with the permeability value of prospects ranged from 2.05 to 4.76% per km2 (highest density value) with general direction is in the southeast-northwest which in line with the Sumatra structural pattern.  Based on geological data, argillic alteration was found with geothermal manifestations consisting of hot springs. Through geochemical analysis, the fluid type of hot water sample (temperature of 48.66oC) is in the immature water zone; occur with the presence of carbonate sinter. Geophysical analysis using the magnetotelluric (MT) method to identified geothermal systems such as cap rock with low resistivity (<30 ohm.m) and reservoirs with moderate resistivity (31-300 ohm.m). The correlation between remote sensing, geochemistry, and magnetotelluric could determine the geothermal potential in West Sumatra.

Analysing Efficiency Methods of Polynomial Complexity Degree in Multidimensional OLAP Cube Data Decomposition
Authors: Akhrem A. A. , Nosov A. P. , Rakhmankulov V. Z.
Published: May 2021

The article investigates the problems of reduction (decomposition) of multidimensional data models in terms of hypercube OLAP-structures. Describes the case when a data structure is defined by the array that slices and dices the hypercube into the odd number of subcubes, and this set of subcube structures becomes decomposed. Defines an exact upper bound for increasing a computational performance of methods to analyze OLAP-data on subcubes, which determines the decomposition approach efficiency in comparison with the OLAP-data analysis on a complete unreduced hypercube. A compared efficiency of the hypercube decomposition into two subcubes on the sets consisting of the even and odd number of subcube structures has shown that with considerable data partitioning for methods of a polynomial complexity degree the decomposition efficiency essentially is independent on this factor and rises with increasing complexity degree of methods applied.

When using the mathematical methods to study decomposition (reduction) of large hyper-cubes of multidimensional data of analytical OLAP systems into subcube components, there is a need to find conditions for minimising the computational complexity of methods to solve the problems of the OLAP hyper-cube analysis during data decomposition in comparison with using these methods for analyzing large amounts of information that is accumulated directly in the hyper-cubes of multidimensional OLAP-data to establish the criteria for decreasing or increasing computational performance when applying methods on the subcube components (reduction methods) as compared to applying these methods on a hypercube (non-reduction or traditional methods), depending on one or another degree of complexity of complex methods.

The article provides an accurate quantitative estimate of decreasing computational complexity of reduction methods for analyzing OLAP-cubes as compared to the non-reduction methods in the case when said methods have the polynomial complexity and the original hypercube array of data comprises the odd number of subcubes.

Os três componentes executivos básicos e o desempenho matemático escolar
Authors: Nunes de Santana Alanny , Roazzi Antonio , Melo Monilly Ramos Araujo
Published: May 2021

As Funções Executivas (FE) são importantes preditoras do desempenho acadêmico. Quanto à composição das FE, o modelo da tríade executiva – Memória de Trabalho (MT), Controle Inibitório (CI) e Flexibilidade Cognitiva (FC) – é um dos mais explorados na atualidade. Considerando esse modelo e sua relação com o desempenho matemático escolar, pode-se afirmar a inexistência de dados empíricos que permitam inferir qual componente apresenta maior valor preditivo sobre esse desempenho. Portanto, objetivou-se com o presente estudo quantitativo verificar quais componentes executivos mais se associam ao desempenho matemático e qual é a magnitude dessa relação. Avaliaram-se 110 participantes com idades entre 8 e 12 anos, de escolas públicas e privadas, a partir dos instrumentos Mini-Exame do Estado Mental (Meem), Roteiro para Sondagem de Habilidades Matemáticas (Coruja Promat), Instrumento de Avaliação Neuropsicológica Breve Infantil (Neupsilin-INF), Five Digit Test (FDT) e questionário sociodemográfico. Os resultados das análises estatísticas de correlação e regressão empreendidas revelaram relações significativas entre os três componentes e o desempenho em matemática, com forte predominância da MT, seguida da FC e do CI.

Los Objetivos de Desarrollo Sostenible (ODS) buscan cerrar las brechas que se presentan en gran parte de la población vulnerable en el mundo. En este escenario, la Organización de las Naciones Unidas para la Educación, la Ciencia y la Cultura (Unesco) ha definido como una de sus áreas estratégicas la Educación para la Ciudadanía Global (ECG) a la luz de la meta 4.7 del ODS-4, donde invita a los países a garantizar que todos los alumnos adquieran las competencias, actitudes y comportamientos que promuevan la reconstrucción de las sociedades en un mundo más pacífico y sostenible. Este artículo tiene como objetivo, a partir de la comprensión de la evolución del concepto de ciudadanía global y del mapeo del contexto institucional del desarrollo de la Base Nacional Común Curricular (BNCC), analizar la relación de la competencia general 10 de la BNCC, Responsabilidad y Ciudadanía, con lo que promulga la Unesco respecto de la ECG, mediante una investigación cualitativa no experimental de carácter descriptiva, por medio de una revisión crítica de la bibliografía, apoyada en el sistema de información Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires (Iramuteq). Como resultado, se verificó la estrecha relación de ambos conceptos, una vez que se comprobó que la competencia 10 de la BNCC se ha enmarcado en los lineamientos de la ECG y del ODS-4, y su desarrollo contribuye con el logro de la Agenda de Educación 2030.

Evaluating the Potential Conflicts of Collective Housing Development in the Suburbs of Iași, Romania
Authors: DINTER Oliver-Valentin , ROȘU Lucian
Published: May 2021

In the post-socialist transition, the lack of local regulations regarding the development of the peri-urban area of Iași municipality led towards a chaotic and fast-growing residential expansion. The increasing trend of complexes of collective housing built-out in the outskirts brought new conflicts and enhanced the existing ones, altering the territorial identity and social cohesion of the community. The main purpose of this paper is to deliver a better understanding of the drawbacks determined by the occurrence of these complexes and to analyse the spatial intensity and variation of the conflicts. To determine the probability to generate conflicts for each residential project, an index was computed based on conflict triggering factors. The results display the spatial patterns of different conflict types throughout the peri-urban area of Iași. Conflicts are generated by lowering the price of households with a drawback at fostering the already existing conflicts. Major complexes of collective houses are, in general, the most expensive but they generate a lower score for triggering conflicts, while small or individual complexes, even though they are cheaper, tend to create the most common conflicts. While world planning trends aim at enhancing a sense of community through a balanced planning of the suburbs, in the specific case of Iaşi municipality, the lack of planning and the chaotic apparition of residential projects leads to a more segregated and disrupted community, therefore enhancing more conflicts.

Вопрос разработки муниципальными образованиями Дальневосточного федерального округа собственных стратегий развития приобретает особое значение в контексте решения задач «Национальной программы социально-экономического развития Дальнего Востока на период до 2024 г. и на перспективу до 2035 года». Органам местного самоуправления необходимо обосновать долгосрочные стратегические приоритеты, задачи, механизмы и показатели социально-экономического развития, синхронизировав их с приоритетами, целями и задачами социально-экономического развития Российской Федерации и субъектов ДФО. В статье рассматриваются факторы и предпосылки, влияющие на выбор оптимальной модели стратегического развития муниципального образования на примере Шкотовского муниципального района Приморского края. Приведены результаты анализа стратегического местоположения (потенциала рынка), хозяйственно-экономической специализации, потенциала отраслей экономики, экономико-пространственной характеристики, на основании чего сделано предположение о вероятных сценариях и базовых моделях социально-экономического развития района. Сделан вывод, что модель интенсификации сложившейся экономической системы муниципального образования обеспечивает устойчивое, умеренное развитие экономики темпами 102,0–102,2%. Модель, основанная на поддержке проектов-акселераторов в инновационных сферах, способствует изменению экономического уклада Шкотовского муниципального района с наименьшими угрозами для окружающей среды и населения. Данная модель применима для реализации целевого сценария развития экономики региона с темпами роста 105,3%, что в наибольшей степени соответствует целевым значениям документов стратегического планирования высшего порядка. Ключевые слова и словосочетания: стратегическое развитие, акселерация экономики, добавленная стоимость, инновации.

Digital SGD: Ubin project
Authors: Alekseenko Alexey
Published: May 2021

В статье проводится анализ отчетов Валютного управления Сингапура по разработке государственной платформы блокчейн, позволяющей внедрить и использовать в расчетных операциях сингапурский цифровой доллар. Рассмотрены цель, задачи, этапы и основные итоги реализации проекта Ubin, в рамках которого Сингапур изучил перспективы введения в экономический оборот национальных цифровых валют. Целью данной статьи является предложение на основе изученных отчетов рекомендаций, которые могут быть полезны для модернизации отечественного законодательства в целях реализации проекта по внедрению цифрового рубля на территории России. Было выявлено, что цифровой сингапурский доллар представляет собой не новую форму денег, а средство для расчетов и урегулирования межбанковских обязательств, не имеющее ценности вне этой области. Благодаря взятой за основу системы смарт-контрактов сингапурскую цифровую валюту можно использовать для расчетов по сделкам, в частности, в сфере страхования и в качестве эффективной замены аккредитива. Используемый в проекте Ubin блокчейн характеризуется открытым кодом и позволяет взаимодействовать с другими системами, созданными как частными банками, так и зарубежными финансовыми регуляторами. Благодаря этому стало возможным установить такую экосистему, которая позволяет осуществлять транснациональные расчеты, в том числе в сфере ценных бу- маг. В статье делается вывод о том, что Банку России следует реализовать проект по внедрению цифрового рубля с учетом опыта Сингапура, создав консорциум партнеров и разработав нормативные правовые акты, необходимые для конструирования системы, позволяющей проводить передачу валюты и эмиссионных ценных бумаг между финансовыми организациями. Ключевые слова и словосочетания: криптовалюта, токен, Сингапур, цифровые финансовые активы, цифровая валюта, платежные услуги, стейблкоин, цифровизация, цифровой рубль, блокчейн, финансовые технологии.
