spyro: a Firedrake-based wave propagation and full waveform inversion finite element solver
Authors: Roberts Keith J. , Olender Alexandre , Franceschini Lucas , Kirby Robert C. , Gioria Rafael S. , Carmo Bruno S.
Published: November 2021

Abstract. In this article, we introduce spyro, a software stack to solve acoustic wave propagation in heterogeneous domains and perform full waveform inversion (FWI) employing the finite element framework from Firedrake, a high-level Python package for the automated solution of partial differential equations using the finite element method. The capability of the software is demonstrated by using a continuous Galerkin approach to perform FWI for seismic velocity model building, considering realistic geophysics examples. A time-domain FWI approach is detailed that uses meshes composed of variably sized triangular elements to discretize the domain. To resolve both the forward and adjoint-state equations, and to calculate a mesh-independent gradient associated with the FWI process, a fully-explicit, variable higher-order (up to degree k = 5 in 2D and k = 3 in 3D) mass lumping method is used. We show that, by adapting the triangular elements to the expected peak source frequency and properties of the wavefield (e.g., local P-wavespeed) and by leveraging higher-order basis functions, the number of degrees-of-freedom necessary to discretize the domain can be reduced. Results from wave simulations and FWIs in both 2D and 3D highlight our developments and demonstrate the benefits and challenges with using triangular meshes adapted to the material properties.
Global to regional overview of floods fatality: the 1951–2020 period
Authors: Hamidifar Hossein , Nones Michael
Published: December 2021

Abstract. Floods are among the most devastating natural hazards. Human interferences along with climate change cause a lot of human and financial losses every year following the occurrence of floods. In this research, flooding events that have killed more than 10 people in the 1951–2020 period have been studied, analysing the EM-DAT database. The results show that the severity of flood-related deaths is equally distributed worldwide, but present some specific geographical patterns. The flood fatality coefficient, calculated for different countries, identified that Southern, Eastern, and South-Eastern regions of Asia have the deadliest floods in the world. The number of flood events has been increasing since 1951 and peaked in 2007, following a relatively declining trend since then. However, the number of death tolls does not follow a statistically significant trend. An examination of the number of flood events in different decades shows that the highest number of events occurred in the 2001–2010 decade, which corresponds to the largest precipitation anomaly in the world. The most casualties occurred in the decade 1991–2000. However, the lethality of floods has decreased over time, from 412 per flood in 1951–1960 to 67 in the 2011–2020 decade, probably as a consequence of a more resilient environment and better risk reduction strategies. In addition, a direct correlation was found between the number of flood events and the number of casualties with the world’s population.
Improved ELMv1-ECA simulations of zero-curtain periods and cold-season CH4 and CO2 emissions at Alaskan Arctic tundra sites
Authors: Tao Jing , Zhu Qing , Riley William J. , Neumann Rebecca B.
Published: November 2021

Abstract. Field measurements have shown that cold-season methane
(CH4) and carbon dioxide (CO2) emissions contribute a substantial
portion to the annual net carbon emissions in permafrost regions. However,
most earth system land models do not accurately reproduce cold-season
CH4 and CO2 emissions, especially over the shoulder (i.e., thawing
and freezing) seasons. Here we use the Energy Exascale Earth System Model
(E3SM) land model version 1 (ELMv1-ECA) to tackle this challenge and fill
the knowledge gap of how cold-season CH4 and CO2 emissions
contribute to the annual totals at Alaska Arctic tundra sites. Specifically,
we improved the ELMv1-ECA soil water phase-change scheme, environmental
controls on microbial activity, and the methane module. Results demonstrate that both soil temperature and the duration of
zero-curtain periods (i.e., the fall period when soil temperatures linger
around 0 ∘C) simulated by the updated ELMv1-ECA were greatly
improved; e.g., the mean absolute error (MAE) in zero-curtain durations at
12 cm depth was reduced by 62 % on average. Furthermore, the MAEs of
simulated cold-season carbon emissions at three tundra sites were improved
by 72 % and 70 % on average for CH4 and CO2, respectively.
Overall, CH4 emitted during the early cold season (September and October),
which often includes most of the zero-curtain period in Arctic tundra,
accounted for more than 50 % of the total emissions throughout the entire
cold season (September to May) in the model, compared with around 49.4 %
(43 %–58 %) in observations. From 1950 to 2017, both CO2 emissions
during the zero-curtain period and during the entire cold season showed
increasing trends, for example, of 0.17 and 0.36 gC m−2 yr−1 at Atqasuk. This study highlights the importance of
zero-curtain periods in facilitating cold-season CH4 and CO2 emissions from
tundra ecosystems.
Evaluation of six geothermal heat flux maps for the Antarctic Lambert-Amery glacial system
Authors: Kang Haoran , Zhao Liyun , Wolovick Michael , Moore John C.
Published: November 2021

Abstract. Basal thermal conditions play an important role in ice sheet dynamics, and they are sensitive to geothermal heat flux (GHF). Here we estimate the basal thermal conditions, including basal temperature, basal melt rate, and friction heat underneath the Lambert-Amery glacier system in east Antarctica, using a combination of a forward model and an inversion from a 3D ice flow model. We assess the sensitivity and uncertainty of basal thermal conditions using six different GHFs. We evaluate the modelled results using all available observed subglacial lakes. There are very large differences in modelled spatial pattern of temperate basal conditions using the different GHFs. The two most-recent GHF fields inverted from aerial geomagnetic observations have higher values of GHF in the region, produce a larger warm-based area, and match the observed subglacial lakes better than the other GHFs. The fast flowing glacier region has a lower modelled basal friction coefficient, faster basal velocity, with higher basal frictional heating in the range of 50–2000 mW m−2 than the base under slower flowing glaciated areas. The modelled basal melt rate reaches ten to hundreds of mm per year locally in Lambert, Lepekhin and Kronshtadtskiy glaciers feeding the Amery ice shelf, and ranges from 0–5 mm yr−1 on the temperate base of the vast inland region.
Stratospheric Modulation of Arctic Oscillation Extremes as Represented by Extended-Range Ensemble Forecasts
Authors: Spaeth Jonas , Birner Thomas
Published: November 2021

Abstract. The Arctic Oscillation (AO) describes a seesaw pattern of variations in atmospheric mass over the polar cap. It is by now well established that the AO pattern is in part determined by the state of the stratosphere. In particular, sudden stratospheric warmings (SSWs) are known to nudge the tropospheric circulation toward a more negative phase of the AO, which is associated with a more equatorward shifted jet and enhanced likelihood for blocking and cold air outbreaks in mid-latitudes. SSWs are also thought to contribute to the occurrence of extreme AO events. However, statistically robust results about such extremes are difficult to obtain from observations or meteorological (re-)analyses due to the limited sample size of SSW events in the observational record (roughly 6 SSWs per decade). Here we exploit a large set of extended-range ensemble forecasts within the subseasonal-to-seasonal (S2S) framework to obtain an improved characterization of the modulation of AO extremes due to stratosphere-troposphere coupling. Specifically, we greatly boost the sample size of stratospheric events by using potential SSWs (p-SSWs), i.e., SSWs that are predicted to occur in individual forecast ensemble members regardless of whether they actually occurred in the real atmosphere. For example, for the ECMWF S2S ensemble this gives us a total of 6101 p-SSW events for the period 1997–2021. A standard lag-composite analysis around these p-SSWs validates our approach, i.e., the associated composite evolution of stratosphere-troposphere coupling matches the known evolution based on reanalyses data around real SSW events. Our statistical analyses further reveal that following p-SSWs, relative to climatology: 1) persistently negative AO states (> 1 week duration) are 16 % more likely, 2) the likelihood for extremely negative AO states (< −3σ) is enhanced by at least 35 %, while that for extremely positive AO states (> +3σ) is reduced to almost zero, 3) a p-SSW preceding an extremely negative AO state within 4 weeks is causal for this AO extreme (in a statistical sense) up to a degree of 27 %. A corresponding analysis relative to strong stratospheric vortex events reveals similar insights into the stratospheric modulation of positive AO extremes.

Gender-Based Violence, Law Reform, and the Criminalization of Survivors of Violence
Authors: Goodmark Leigh
Published: November 2021

Criminalization is the primary societal response to intimate partner violence in the US. This reliance on criminal legal system interventions ignores several unintended consequences. One of the serious unintended consequences of criminalization — perhaps the most serious unintended consequence — has been the increased rates of arrest, prosecution, conviction, and incarceration of those whom criminalization was meant to protect: victims of intimate partner violence. Criminalized survivors follow a variety of pathways into the carceral system, which fails to recognize their status as victims of violence and punishes them for failure to conform to victim stereotypes as well as for their acts.
Why Decriminalise Prostitution? Because Law and Justice Aren’t Always the Same
Authors: Scoular Jane , FitzGerald Sharron
Published: November 2021

Leigh Goodmark’s work on domestic violence argues for alternatives to criminal justice to ‘solve’ issues of gendered violence. The criminalisation of sex work and prostitution is rarely discussed in this context—a rather odd omission given the increasing trend towards ‘criminalising demand’ and counter-calls for decriminalisation in this domain. In this article, we bring the two debates into conversation, using Goodmark’s work to bring analytical clarity to the prostitution debate and connect sex work to wider social justice debates in feminist anti-violence circles. We aim to move the conversation beyond retribution and the view that law is justice to outline a vision of justice for sex workers grounded in the principles of rights, recognition and representation. By contextualising the decriminalisation of prostitution within the framework of a wider anti-carceral justice movement, we seek to build alliances for social justice that transcend the current divide.
Judicial Restorative Justice and Domestic Violence in Brazil: Setting Problems and Challenges from the Field
Authors: Campos Carmen Hein , Oliveira Cristina Rego
Published: November 2021

The solution of conflicts, cases of violence and harmful offences through alternatives to the penal system has been encouraged by Brazil’s Conselho Nacional de Justiça/National Justice Council (CNJ) since 2010. However, empirical studies that assess the impact of restorative practices when applied to domestic violence cases are sparse because most of them tend to highlight the retributive model’s insufficiency compared to the restorative model. In attempt to break away from that logic, the article analyses the insertion of practices of restorative justice regarding domestic violence by examining empirical studies carried out at the Rio Grande do Sul’s Justice Court, a pioneer in the employment of restorative justice. The study shows that restorative practices for domestic violence are residual, do not disrupt the traditional model and are not understood as restorative by women. Therefore, a broad and serious discussion about the model being implemented in Brazil is needed.
Navigating the Family Law Provisions: Migrant Women’s Voices
Authors: Borges Jelinic Ana
Published: November 2021

This article considers the voices of migrant women engaging with Home Affairs to guarantee permanent residency (PR) in Australia after experiencing domestic violence. Data collected from longitudinal interviews with 20 participants were considered, with two participants’ stories analysed in detail. The research indicates how the legal immigration system is set up in a way that does not listen to women and disadvantages them. Particular issues pointed out include extended timelines, lack of concern for cultural differences and inconsistencies in the process, and how they affect women undermining the goal of the law, which is to protect migrants from sponsors’ violence.
Locked Down with the Perpetrator: The Hidden Impacts of COVID-19 on Domestic and Family Violence in Australia

Published: November 2021

Prior to the COVID-19 global pandemic, domestic and family violence (DFV) had been recognised globally as an epidemic in its own right. Further, research has established that during times of crisis and/or after disasters, rates of DFV can escalate. The COVID-19 pandemic has been no exception, with emerging research from around the world confirming that the public health measures and social effects associated with COVID-19 have increased the frequency and severity of DFV in various countries. In contributing to this evolving body of literature, this paper reports on the findings of a national research project that examined the impact of the COVID-19 global pandemic on DFV in Australia. This nationwide survey of service providers indicates the public health responses to COVID-19 such as lockdowns and travel restrictions, while necessary to stem the pandemic, have had profound effects on increasing women’s risk and vulnerability to domestic violence, while at the same time making it more difficult for women to leave violent relationships and access support. However, this vulnerability is not evenly distributed. The pandemic pushed marginalised voices further underground, with many unable to seek help, locked down with their abuser. Our survey sought to amplify the experiences of culturally and linguistically diverse (CALD) communities; Indigenous communities; lesbian, gay, bisexual, transgender, intersex, queer, + (LGBTIQ+) communities; women locked down with school-age children; those already in violent relationships; and those whose first experience of domestic violence coincided with the onset of the pandemic. For logistical and ethical reasons, we could only access their voices through the responses from the domestic violence sector.

Published: November 2021

Equal access to safe transport is increasingly conceptualised as a fundamental right for women, with demonstrated impact on health outcomes, social and economic mobility, and societal participation. This study analysed qualitative and quantitative data to examine travel patterns and experiences among 200 women (aged between 18-64 years) using paid transport for work or educational purposes in Bangladesh. Results showed that the women faced multiple threats to their safety, including gender-based violence, harassment and crime, and traffic and non-traffic injury and that the use of paid transport was associated with high levels of anxiety and fear. Despite these circumstances, the women were captive travellers, forced to make transport choices based on price, availability, and ease of travel rather than safety. Unable to choose safe transports, the women attempted to mitigate risks by changing their travel pattern and behaviour, and by restricted their travel frequency. These findings are discussed within the context of women’s rights and mobility justice.
Propuesta de apoyo a personas con capacidad modificada desde el trabajo social. El caso de las entidades tutelares
Authors: Dorado Barbé Ana , González Casas David , Rivera Alvarez Joaquín María , Sojo Belinchón Rocío
Published: December 2021

La Convención de Naciones Unidas sobre derechos de personas con discapacidad (2006) modificó sustancialmente el escenario de la discapacidad. Dicha transformación se ubica en un cambio de perspectiva en referencia a dejar de contemplar la discapacidad bajo un modelo biosanitario rehabilitador, para pasar a un modelo que considera a las personas con discapacidad como sujetos titulares de derechos y en el que los poderes públicos destacan en su obligación de garantizar que el ejercicio de dichos derechos sea efectivo y pleno.

En base a ello, se reflexiona sobre el nuevo escenario jurídico y social y se propone un modelo de atención social a desarrollar desde Entidades Tutelares desde la perspectiva del Trabajo Social. Dicha propuesta pretende aunar los nuevos paradigmas de intervención y servir de herramienta metodológica a las Entidades Tutelares en la España del siglo XXI.

Published: December 2021

Partiendo de la premisa de que la actividad comunicativa es un factor clave en el desempeño organizacional este trabajo de investigación analiza la gestión que las cooperativas españolas hacen de su comunicación. Dada la relevancia que estas organizaciones tienen para el desarrollo económico y social del país y la escasez de estudios que abordan este tema, se ha considerado de importancia desarrollar este estudio para determinar si las cooperativas han asumido la comunicación como una herramienta relevante para su desarrollo y si gestionan la misma de una manera adecuada. Para ello se ha aplicado la metodología cuantitativa de la encuesta a una muestra de 338 cooperativas españolas. De los resultados se desprende que las cooperativas, si bien aún no se encuentran en una fase avanzada en cuanto a la gestión de comunicación que realizan si que presentan algunos aspectos en su gestión que permiten ser optimistas de cara al futuro.
Pitiakhshs in Iberia in Classical Epoch
Authors:   Georgian National Museum, Bragvadze Zurab
Published: November 2021

Artifacts found in Village Bori in 1902 are kept in the Hermitage in Sankt Petersburg. Among the finds particularly interesting is a silver cup with an Aramaic inscription:” Kind Pitiakhsh Buzmihr”. The inscription revealed that there existed an institution of pitiakhsh in the kingdom of Iberia in Roman epoch. Indeed, it is interesting whether the grave which yielded the mentioned object was the tomb of a pitiakhsh. The point is that in Bori no sarcophagi or crypts are encountered, there are only pit-burials there which, in my opinion, excludes presence of a pitiakhsh’s tomb in the area and the rich inventory recovered together with the bowl in question does not belong to a pitiakhsh. It is more likely that the bowl had been presented by Pitiakhsh Buzmihr. The Roman-period kingdom of Iberia knows a few similar cases. But where exactly is Pitiakhsh Buzmihr’s grave? The question has not been answered yet. Apart from other issues, the article deals with the chronological order of the pitiakhshs of Armaziskhevi cemetery and suggests that pitiakhs are buried only in graves NN 1, 2 and 3. Furtheremore, it discusses the problem of interrelationship between the pitiakhs’ graves and the structures found in Armaziskhevi and passes an opinion that the structures date to an earlier period than the graves. In the 70s (not later than 75 AD), the residence was destroyed by an earthquake and since then the area was used as a cemetery of pitiakhshs of Armaziskhevi and their family members.

Published: November 2021

Background: Locoregional management in breast cancer patients includes surgery and radiation. Radiation increases the risk of the decreasing of cardiac ventricular performance and known as cardiotoxicity. This study aims to analyze the relationship between radiation exposure in locally advanced breast cancer patients with the left ventricular systolic function.
Methods: The subjects in this study were patients with locally advanced breast cancer who underwent external radiation therapy after surgery procedure at Dr. Soetomo General Hospital in January 2021 – April 2021. Examination of left ventricular performance parameters was carried out using an invasive method, the transthoracic echocardiography. The performance parameters examined were left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS).
Results: A total of 45 patients were recruited in this study. Twenty-two patients (22/45; 48.9%) underwent radiation therapy from the left side and 23 patients (23/45; 51.1%) from the right side. After external radiation, the number of patients with left ventricular dilatation were increased. On the left side, there were 6 patients (6/22; 27.6%) who experienced dilatation compared to before radiation (3 patients), while on the right side of the body there were 8 patients (8/22; 34.8%) who experienced dilatation compared to before radiation (6 patients). There was an increase in the number of patients who experienced a decrease in EFT and EFB after radiation, although the association was not significant. Almost all patients experienced a decrease in GLS values ​​after radiation (44/45; 97.8%).
Conclusion: There was an increase in the number of patients with left ventricular dilatation and decrease in EFT and EFB values after external radiation. Decreased GLS values ​​were found in almost all patients who underwent external radiation in this study.

Keywords: Radiation, locally advanced breast cancer, LVID, ejection fraction, GLS.

Measles has remained endemic in some part of the world where the vaccine is not easily accessible. Although vaccine is available in some parts of the world, with routine immunization services and campaigns, many children are yet to be vaccinated. Hence, this study assessed the knowledge and attitude towards measles and Measles, Mumps and Rubella vaccine (MMR) among mothers in Idi-aba community. This was a descriptive research design using multistage sampling technique to choose participants for the study. A self-constructed questionnaire was used to collect information from participants. After the distribution and collection of the questionnaires, data was analyzed using descriptive statistics. Results showed that 93.2% (386) and 65.9% (273) participants indicated that they knew what measles and MMR vaccines are respectively. However, overall analysis revealed that only 165 (39%) participants had high knowledge of measles and MMR vaccine while 303 (74%) had good attitude towards measles and MMR vaccine. This study showed that there are some knowledge gaps.  Factors significantly associated with high percentage of mothers having good attitude are occupation (????2=20, P=0.000), income (????2=5.9, P=0.009) and parity (????2=23, P=0.000). In conclusion, this result implies that in order to sustain the good attitude displayed by the mothers, there is need for strategic intensive health educational programs for the mothers of the community.

According to Porter (1985), in the market of competition, competitive advantage lies in the center of business activities of an enterprise. For this reason, one of the most important factors for any kind of business is to build or construct a good and stable competitive advantage. The wealth of a company cannot be durable if the company does not maintain its competitive advantage. Improving the competitive advantage is one of the first and foremost concerns of every business. In the process of integration, all economies have to try their best to fully compete with each other to gain the best. Among the economy sectors, the retail enterprises are of those who have to apply marketing strategies to strengthen their competitive advantage. With good and suitable marketing strategies, businesses can increase the number of their customer, have goods and products attractive to consumers and finally gain the expected profits. In Vietnam, the market economy started at the end of 1986, much later than the world market economy, so the application of competitive advantages from the macro level to micro level (here the enterprise level) has been slow. For the sector of retailing, especially supermarket retailing, the market scale of Vietnam is much smaller than that of other markets in the region. However, there are basic factors for a fast development in Vietnam such as: big population with the kind of young population, high rate of economic growth rate and non-stop improved living standard. That is the fact that the potential for retailing development in Vietnam is not small and supermarket business in the future is big. In Vietnam, especially in Ho Chi Minh market, there are quite a lot of supermarket chains which are in operation nowadays such as Co-op mart, Citimart, Maximart, B-smart, Shop&Go and so on? These supermarkets are trying their best to gain more customers. For this purpose, the researcher chose Citimart as a case study in this research. Citimart is one of most favorable supermarket in Ho Chi Minh. In this thesis, the researcher studies the factors affecting the competitive advantage of Citimart, and then find out the solutions for the policy makers to have good business strategies of Citimart.

Repeated intrathecal application of the sustained release steroid Triamcinolone Acetonide (TCA) is beneficial in progressive Multiple Sclerosis (MS) patients [1]. Particularly, patients with spinal lesions often show a distinct benefit with a three fold increase of the maximum walking distance [2]. This therapy ameliorates walking distance, improves upper limb function and reduces spastic symptoms [1]. The putative regenerative effect may result from declined synthesis of the repulsive guidance molecule A [3]. Visualization of air bubbles after a TCA injection prompted this case report.

Background: Multiple myeloma is a relatively common type of plasma cell dyscrasia, in which monoclonal plasma cells proliferate. This frequently leads to anemia, renal failure, hypercalcemia and bone lesions. Primary plasma cell leukemia is a much rarer type of plasma cell dyscrasia, with measurable plasma cells in the blood circulation and usually more acute presenting signs. Case: A 57-year-old woman presented to the emergency department with dyspnea. Because of hypoxemia due to a hemoglobin concentration of 3.1 g/dL (1,9 mmol/L), asystole occurred, and cardiopulmonary resuscitation had to be started. The severe anemia turned out to be due to a primary plasma cell leukemia. Palliative treatment was started with combination chemotherapy with VTD (bortezomib, thalidomide and dexamethasone) with a very good partial response, after which she proceeded to an autologous stem cell transplantation with high dose melphalan conditioning. Conclusion: Primary plasma cell leukemia is a plasma cell dyscrasia with both resemblances and differences from the better-known multiple myeloma. It is less common, but presenting signs often are more acute and more severe. Currently there is no curative treatment. Keywords: Plasma cell leukemia; Hematological emergency; Multiple myeloma; VTD.

ackground: An entrapped rotablator burr is a rare but severe complication of Rotational Atherectomy (RA), and surgical removal is invasive and takes several hours. Therefore, a less invasive measure is necessary for this complication. Case summary: A 54-year-old man with Diabetes Mellitus (DM) and hypertension revealed chronic total occlusion in the proximal LAD In-Stent Restenosis (ISR). The left coronary ostium was engaged with 7Fr EBU. A Runthrough was inserted into D1, and the XTR guidewire was inserted into distal LAD using Guideliner catheter. Because of the severe angulated calcified lesion at the proximal LAD, the 1.0 balloon could not pass the lesion, so we performed rotablation. The burr suddenly became trapped within the calcified lesion at the distal angulated edge. We performed a gentle manual retraction of the rota and attempted to insert another guidewire to alongside the burr for balloon dilation to free the burr, but wiring failed. Then, we cut off the drive sheath of the rota, inserted a 5.5 Fr Guideliner catheter through the remaining system and fixed the catheter tip near the entrapped rotablator burr by pushing and pulling the rotablator at the same time. Finally the rota system was removed successfully, but the burr was nearly detached from the rota wire during retraction. Discussion: We might get an information of the degree of fibrous and angulated calcification by MDCT before PCI and this will be helpful to predict the possibility of bur stuck. A large size sheath and femoral approach may be preferable.
Model Order Reduction and Physics-Based Machine Learning: Challenges, Progress, and Impact
Authors: Farhat Charbel
Published: November 2021

While machine learning algorithms have been around for a long time, many were developed under different names. Collectively, Projection-based Model Order Reduction (PMOR) methods constitute a case in point. They have been data-driven, physics-informed, machine learning methods since their inception, before these buzzwords became fashionable. For parametric linear problems, they are mature and have already made some impact in industry. For parametric nonlinear problems, their state of the art has been significantly advanced during the last decade on all of theoretical, algorithmic, and application fronts. Furthermore, many rational myth theories about PMOR have been debunked, particularly for highly nonlinear problems. Impressive results have been demonstrated for complex geometries and industrial-grade problems in many applications including nonlinear multi-scale solid mechanics, nonlinear structural dynamics with contact, convection-dominated turbulent flows, wave propagation in both the frequency and time domains, linear and nonlinear multi-disciplinary shape optimization, and uncertainty quantification. On the other hand, high-dimensional parameter spaces, topological changes, and the Kolmogorov n-width issue remain outstanding challenges; nevertheless, significant progress has also been made in these areas. First, this talk will rapidly overview the aforementioned state assessment of PMOR. Next, it will contrast the state of the art of this computational technology with alternative, popular, surrogate modeling techniques including those based on artificial neural networks, before presenting a recently developed, disruptive PMOR approach and reporting on its performance for real-world applications. Then, the talk will discuss the concept of mechanics-informed neural networks for data-driven constitutive modeling, where the informing process is not associated with any physics-based residual or differential equation, but with teaching a neural network mechanics concepts such as objectivity, isotropy (as needed), consistency, material stability, and dynamic stability. Finally, the talk will report on applications pertaining to the recent landing of Perseverance on Mars.

Published: November 2021

The article analyzes the institutional provision of the regulatory functions of the state in such areas as artificial intelligence and robotics. The analysis is based on the Concept of the development of regulation of relations in the field of artificial intelligence and robotics technologies until 2024. Among the problematic areas of regulation are the restriction of competition, the loss of flexibility in economic relations and the market disequilibrium. It is shown that the solution of these problems requires an integrated approach. So, to implement the concept of “smart city”, it is necessary not only to weaken or remove regulatory barriers, but also to use additional tools that have already applied in the world practice. An opportunity of applying of theoretical and methodological base of quality economics is considered. The solution to a significant part of the problems of digitalization of the region’s economy is the use in the management of the development of the “smart city” the international standard “Sustainable cities and Communities – Indicators for smart cities”.
