Skilled Immigration and its Impact on Ontario’s Unemployment Rates
Authors: Sandal Ravdeep
Published: January 2025

This study exploits policy differences across Canadian provinces to analyze the effects of skilled immigration on the unemployment rate. In 2005, Ontario signed its first Provincial Nominee Program agreement. In 2007, Ontario adopted and began to utilize the Provincial Nominee Program, a program designed to fill labour shortages and meet economic demands. To analyze the impact of such a policy, Ontario is compared to Quebec, which has not adopted the Provincial Nominee Program. This report utilizes ARIMAX models to find the impact of this skilled labour program on unemployment levels. The results demonstrate that the introduction of the Provincial Nominee Program in Ontario has led to a statistically significant decline in the unemployment rate. Hence, this inflow of skilled labour provides a net benefit, which has implications for more liberal policies regarding skilled migration.
Modeling Social Learning Using Dyna-Q and Ant Colony Optimization
Authors: Zimmermann Renato
Published: January 2025

This paper introduces a novel way of modeling social learning in macroeconomics using techniques from model-based reinforcement learning and ant colony optimization. The work extends previous works in bounded rationality and social learning by providing tools to complement previously-distinct models in adaptive learning. We test these new techniques using simulations of job search and consumption. Results demonstrate that models fit using the proposed techniques can learn core economic behaviours given no information about the environment, but do not fully fit reward functions in line with rational expectations theory.
Advances in Usability and Performance of a Linear Stapler-Cutter
Authors: Pineda Jonathan , Clymer Jeffrey W , Ricketts Crystal D
Published: January 2025

Background: Linear staplers are widely utilized in a variety of surgical procedures to cut, remove, and connect tissue with technology that is constantly evolving and improving. The Echelon Linear Cutter was recently launched with improved tissue handling via Gripping Surface Technology (GST), advanced 3D staple formation, and an ergonomic design with locking halves for one-handed operation. This study was performed to compare the new stapler to the previous version, the Proximate Linear Cutter.

Methods: Comparisons between the two staplers were performed in porcine models to evaluate staple formation, compression uniformity, leakage at the staple line, and tissue grasping force. Surgeons evaluated the usability and performance of the Echelon stapler in a simulated procedure.

Results: Compared to the Proximate stapler, the Echelon Linear Cutter had significantly lower rates of malformed staples in thin (colon) and thick (stomach) tissue. In addition, results showed the new stapler had more uniform compression, higher tissue grasping force, and higher leak pressure at the staple line. Surgeons found the new stapler easy to assemble, control, place with one-hand without assistance, and capable of capturing thick tissue.

Conclusion: In preclinical testing, the new Echelon Linear Cutter with GST, 3D staples, and locking halves allowing for one-handed device placement offers improved tissue manipulation, stapling and ergonomics compared to the previous stapler. Clinical testing is necessary to determine whether these benefits extend to patient outcomes.

Authors:   Kutafin Moscow State Law University (MSAL), Moscow, Russian Federation, LEVUSHKIN A.N. , KIM V.O. ,   Vnukovo Aircraft Repair Plant No. 400 JSC, Moscow, Russian Federation
Published: January 2025

This scientific article is devoted to the legal structure established by clause 3 of Article 310 of the Civil Code of the Russian Federation, namely, the fee for renunciation of the contract. This design is a contractual condition that is established by entrepreneurs in order to ensure the stability of legal relations. Public interference in such contractual relations is excluded, however, only until the moment when mandatory norms of the law begin to be violated. In this case, the most pressing issue for the law is the limits of such interference, in particular, judicial. There is no legislative provision for the possibility of reducing the established fee for withdrawal from the contract. At the same time, to date, the Supreme Court of the Russian Federation has established conditions under which a reduction in the amount of payment stipulated by the contract can be made, which in practice creates a wide scope of judicial discretion. The author of the article, referring to the opinions of honored domestic lawyers, as well as to key acts of judicial practice, presents his position on the content and specifics of the implementation of conditions that allow reducing the amount of fees for renunciation of the contract.
LEGAL AND PRACTICAL PROBLEMS OF DEFINITION OF GOODS IN PUBLIC LAW REGULATION OF FOREIGN TRADE
Authors:   Russian Foreign Trade Academy of the Ministry of Economic Development of the Russian Federation (RFTA), Moscow, Russian Federation, KHALIPOV S.V.
Published: January 2025

Objectives of the study. The material of the article considers the legal concept of goods in public law regulation of foreign trade. The substantive characteristics of the term in question undergo a critical analysis. International, regional and national legal foundations of foreign trade turnover are analyzed. Different types of official wording of goods in the law of the Eurasian Economic Union and in the Russian legislation are investigated. Research into causes hindering a common interpretation of goods is conducted. The practical consequences of law enforcement and judicial discrepancies, examples of specific conflict situations arising from customs legal relations are demonstrated. Major and minor criteria are established for the general definition of goods both imported into and exported out of the country in the context of Russia's membership in the Eurasian Economic Union.

Conclusions. As the objectives of the study are achieved, the author's position of a legal interpretation of goods is formed. It is proposed to include materiality and customs classification in accordance with the Commodity Nomenclature of Foreign Economic Activities of the Eurasian Economic Union as the main defining criteria of goods. The derived features will serve as the possibility of transfer of goods across the border (the customs border of the Union and/or the state border of Russia) by any means of transportation, including the accompanied baggage of individuals crossing the border. The derived features clarify wording such as “arrival of goods on the customs territory of the Union by any means”, thus excluding the transmission of information via the Internet.

Published: January 2025

Problems. The presented article examines the problem of integrating digitalization into legal activity, which has actualized questions about the ethical and moral aspects of training specialists in the field of law on the basis of new value-semantic aspects of legal education, which sharply increased the requirements for lawyers of the new formation. It is stated that the success of a modern lawyer is due not only to the presence of certain elements of information culture in his arsenal, but also to the practical mastery of digital competencies at a sufficiently high level, which creates the need to reform the legal education system as a whole. Research methods. The author used methods of system analysis, synthesis and modeling. The results of the study. The author concludes that the digitalization of legal education can be considered as a positive phenomenon requiring the search for new approaches to its improvement, and the process of digital transformation of the legal education paradigm is inevitable and expedient. This conclusion is confirmed by the results of studies that have shown that with the use of new tools, algorithms for the movement of mental processes (their intensity, duration, sequence) change in humans. The substitution of some functions by others leads to a restructuring of the entire structure of behavior.

Authors:   Kutafin Moscow State Law University (MSAL), Moscow, Russia, KRUCHININA N.V.
Published: January 2025

This article presents various scientific standpoints on the definition of biomedicine. The issues related to the application of biotechnology in medicine are highlighted. It is concluded that biomedical achievements allow to identify mechanisms of diseases, to produce new medical products and drugs, thus widening possibilities to more effectively make diagnosis and treatment. The paper defines the main areas of biomedicine: transplantation of human organs, vaccination, and assisted reproductive technologies. Due to the shortages of human organs and tissues fit for transplantation, modern additive technologies (3D bioprinting) seem the most promising for introducing into medical practice. The paper confirms that especially biomedicine helps to reduce patients’ mortality, as well as to increase their life expectancy and the birth rate in order to address the demographic problems. Ethical and legal problems linked to the use of the achievements of biomedicine are identified. Still there are some medical technologies which are in conflict with centuries-old cultural and religious values. When researching, including the procedures of medical experiments, scientists have to resolve ethical issues. Criminal risks associated with the use of biomedicine are identified. Criminally dangerous and most vulnerable in this respect might be human organ transplantation, pharmaceuticals, biomedical research on human beings, and assisted reproductive technologies. The article stresses that the improvement of legislation in the field of biomedicine should keep on going.

Rethinking Writing Assignments for Advocacy, Discovery, and Democracy
Authors: Gentry Bobbi
Published: January 2025

Writing assignments do not need to be a chore in our classrooms. We can create engaging assignments that encourage our students to think about problems in their communities, states, and nation; and work towards advocating for change in our democracy. By moving away from the typical research paper assignment for classes, this work considers teaching students how to advocate for solutions to problems that they identify in their community, and, at the same time, discover what issues they care about and who they are politically. Four assignments will be discussed and explanations for discovery, advocacy and impact on democracy examined. Rethinking how we teach writing assignments in our classes is necessary because we are teaching our students to be engaged citizens and active participants in their democracy in contentious times.
DC to AC Converter Frequency Speed Drive Mosfet H-Bridge Topology with Fixed Frequency PWM Sine
Authors: Henky Kurnia Dhany  , Budhy Setiawan  , Sapto Wibowo
Published: January 2025

This paper focuses on simulating a Frequency Speed Drive (FSD) which can regulate frequency changes of 2 to 50 Hz sine wave voltage of 220 Volt RMS. Increasing the frequency of the voltage source provided to the induction motor is expected to increase the rotation speed of the single phase induction motor. This research was carried out by simulating electronic circuits and creating firmware that can regulate the speed of the sine frequency using the PWM (Pulse Width Modulation) Chopping technique with a fixed frequency. Because the PWM Chopping frequency is fixed, the lower the sinusoid frequency the more PWM Chopping will be produced for one wave. Conversely, the higher the frequency of the sinusoid, the less PWM (Pulse Width Modulation) Chopping for one wave will be produced. With this technique, a SPWM wave is produced with a variable frequency and an effective voltage value that is close to a pure sinusoidal wave.
Steady-state Optimization of Modelica Models and Functional Mockup Units with Pyomo
Authors: Gohl Jesse , Tummescheit Hubertus , Andersson Robin , Stuber Matthew
Published: January 2025

This paper describes two ways on how to interface Functional Mockup Units (FMUs) and Modelica models through the Pyomo’s foreign function interface with Pyomo. Pyomo is a Python-based, open-source optimization modeling language with a diverse set of optimization capabilities. Modelica has arguably much better modeling capabilities than Pyomo, but Pyomo integrates excellent optimization solvers, such as Ipopt (Wächter et al. 2006), and provides a good optimization infrastructure. The Interface has been developed in the context of a NAWI, (National Alliance Water Innovation) Hub project in collaboration with the University of Connecticut and Sandia National Labs. The optimization has been set up and tested within Modelon’s Modelica platform Modelon Impact. An unpublished, detailed multi-effect desalination plant developed by Prof. Matt Stuber in the context of (Stuber et al., 2015) has been used to demonstrate the capabilities, as well as simple test models, and design models from Modelon’s commercial Libraries.
Modelica as Model Aggregator for Holistic Architecture Validation of Electric Vehicles
Authors: Gottschall Marcel , Blochwitz Torsten , Abel Andreas , Magdanz Alex
Published: January 2025

Automotive OEMs and suppliers are facing recent challenges in the development process, induced by ever shortened product cycles, further distributed development as well as increasing demands for virtual testing and certification using virtual proving grounds or digital twins.This paper presents a real-life demonstration of a federated, seamlessly integrated design process for a complex cyberphysical system (electric truck), where simulation is used for early-stage performance validation and decision making. Since holistic, but abstract architecture models created in systems engineering discipline contain relevant information with respect to logical system structure and allocated requirements, the simulation domain will benefit from a cross domain linking of model artefacts. By aligning system interfaces across model abstractions and augmenting logical models with physical information, behavioural model templates for design can be generated in a smart, traceable and automated fashion. With the additional information of requirements allocated to certain architectural components in those abstract architecture models, it is demonstrated how scenario-based component and system simulation will contribute to analysis tasks like architecture exploration or specific design optimization in efficient, continuous engineering environments.
Dynamic Modeling Methodology for Near Isothermal Compressor
Authors: Liu Haopeng , Aute Vikrant , Hwang Yunho , Lee Cheng-Yi , Muehlbauer Jan , Gao Lei
Published: January 2025

Compressors are the vital component of the vapor compression systems and account for the majority of energy consumption. Developing appropriate controllers or optimizing compressor design can significantly reduce the carbon emissions. The isothermal compressor combines the compressor chamber and gas cooler, using the liquid piston to compress the working fluid for nearisothermal compression. This methodology can reach up to 30% energy saving compared to the traditional isentropic compression work. This paper leverages the CEEE Modelica Library (CML) to demonstrate a detailed isothermal compressor model that captures the nearisothermal compression process of transcritical carbon dioxide (CO2) cycle. The model uses the real experimental data as the boundary conditions, and the relevant component-level experimental validation was carried out by using a prototype with 1-ton nominal capacity. The results proved the accuracy of the dynamic model (7.5% relative error for chamber pressure and 0.74 K deviation for chamber temperature), and provide a guideline for designing the isothermal compressor chamber. Finally, the modeling for the isothermal compression cycle is ongoing and the field is still in its infancy.

Published: January 2025

A thermo-fluid modeling framework is being developed for ExaDigiT—an open-source framework for developing comprehensive digital twins of liquid-cooled supercomputers. The work is being conducted in two parts, and discussion is divided into two companion papers. The work documented in this paper focuses on the development of a cooling system library in Dymola for the Frontier supercomputer at Oak Ridge National Laboratory. The second part, outlined in a companion paper, focuses on a templating structure called Auto-CSM for easily creating modelagnostic, physics-based thermo-fluid cooling system models for liquid-cooled supercomputers using a text-based schema. The cooling model is being developed using primarily the open-source Transient Simulation Framework of Reconfigurable Models (TRANSFORM) library. The library follows the templating architecture developed within the TRANSFORM library for modeling subsystems. A full-system validation was performed to validate a very simple model that is integrated with the system controls, and the results are presented herein.

Context-aware systems are widespread in our daily lives, but modeling languages that address the notion of context are rare. Variable structure systems (VSS) allow for structural and behavioral changes in physical models at runtime (while the simulation is running) based on different situations. It is desirable to explicitly describe under which contextual situation a specific variant of the simulation model should be used and how to implement the switching between these variants at runtime. In this case, contexts could be used to control the variability of context-aware systems. Equation-based modeling languages are suitable for modeling complex multi-domain, multi-physical systems, and among them, Modelica is the state-of-the-art. Unfortunately, the capabilities for VSS in Modelica are strongly limited. As a result, several frameworks have been proposed to address this problem by supporting different VSS types. However, it remains unclear which framework contributes to which VSS type. Furthermore, approaches have been developed to support VSS, but none can explicitly describe contexts and their transitions. In this work, we first introduce VSS and its different types. Then, we provide an overview of which framework targets which VSS type. Finally, we propose a new language extension based on Modelica, ContextModelica, that provides semantics for the direct context definition, enabling the use of context to control and manage variability.
Integrating the IEEE/CIGRE DLL Modeling Standard to Use “Real Code” Models for Power System Analysis in Modelica Tools

Published: January 2025

Vendors of power system simulation tools are investigating the incorporation of actual controller code into specialized simulation environments. To facilitate this, IEEE and CIGRE have collaboratively created the IEEE/CIGRE DLL Modeling Standard. However, adoption by simulation tool providers has been minimal. The limited adoption is because 'real code' models per the IEEE/CIGRE DLL Modeling Standard must be provided as DLLs by equipment vendors. Thus, to support the standard, tools need to support a standard-specific interface and provide additional functions to execute the models.This paper presents a method for integrating 'real controller code' models (RCMs) built according to the IEEE/CIGRE DLL Modeling Standard into Modelica-based tools. This is achieved by linking precompiled C code to Modelica models and using components from the OpenIPSL library. The approach is demonstrated with an RCM of a simplified silicon-controlled rectifier excitation system (SCRX). The paper discusses the details of the implementation, challenges, and solutions. The findings show that this method allows RCMs to be used in Modelica tools for power system simulations, providing a valuable alternative to specialized simulation tools.
Event Support for Simulation and Sensitivity Analysis in CasADi for use with Modelica and FMI
Authors: Andersson Joel , Goppert James
Published: January 2025

CasADi is an open-source framework that can be used to efficiently solve optimization problems involving user-defined ODE/DAE models. Supported solution methods include so-called shooting methods, where solvers for initial-value problems in ODEs or DAEs are referenced inside nonlinear programming (NLP) formulations. In order to solve such NLP formulations with gradient-based algorithms, CasADi implements a fully automatic sensitivity analysis. This analysis includes forward sensitivity analysis, adjoint sensitivity analysis as well as the calculation of higher-order sensitivities for the ODE/DAE models. Because of the variational (differentiate-then-integrate) approach used, the numerical solution can be performed with variable-step size, variable-order integrators such as those from the SUNDIALS suite.In this work, we present a generalization of the sensitivity analysis support in CasADi to systems with events, as are common in real-world cyber-physical models. In particular, the event extension enables us to formulate and solve optimization problems with such event systems, without a priori knowledge of the number and ordering of events. Ultimately, we expect the proposed approach to be compatible with general cyber-physical models formulated in Modelica or available as model-exchange FMUs.We demonstrate the proposed approach for two proof-of-concept examples; the classical bouncing ball written in CasADi directly and a simple hybrid DAE describing a breaking spring formulated in Modelica and imported symbolically into CasADi. In the examples, we show that the forward sensitivities calculated to high precision using the proposed approach are consistent with a cruder finite-difference approximation and provide an example of how they can be embedded into optimization formulations. We discuss how the approach can be extended to handle standard FMUs, adhering to FMI 2 or FMI 3, as well as non-trivial Modelica models imported via a symbolic interface based on the emerging Base Modelica standard.

Introduction. Analysis of the significance of the Filatov Dynasty Museum
of the History of Medicine as a cultural and educational center that builds
respect for medical traditions and history is the central theme of the
study. The museum was established to preserve the achievements of
Russian physicians, as well as to popularize medical knowledge among
students and a wide audience. Special attention is paid to the role of the
museum in the educational process of the N. P. Ogarev National Research
Mordovian State University. Methods. The study used a comparativehistorical approach to assess the impact of the museum exposition on
the development of medical education. The authors analyzed students'
research and term papers on the history of medicine, as well as archival
documents, photographs and other materials provided by the museum.
The research methods included the study of the historical evolution of
expositions and their interaction with educational processes. Results and
Discussion. The results of the study demonstrate the importance of the museum not only as a place to preserve historical artifacts, but also as
an important element of the educational environment. Students were
actively involved in the creation of the expositions, which helped them to
gain a deeper understanding of the history of medical development. The
museum exhibits, including unique albums and photographs, allow tracing
the development of medicine in Mordovia since the late 19th century,
including the work of rear hospitals during World War II. Conclusion. The
Filatov Dynasty Museum of the History of Medicine plays an important
role in preserving cultural heritage and transferring knowledge to
future generations of doctors. It serves not only as a source of historical
information, but also as an inspiration for students, encouraging them
to further scientific search and improvement of the medical profession.
Museums of the history of medicine are a treasure trove of information,
allowing you to dive into the history of medicine and understand
its problems. The collections provide an opportunity to reconstruct
chronological relationships, assess the level of medical development in
different eras and trace the contribution of individual researchers to the
development of medicine and health care in the country.
