Analysis of the forces acting from the side of the magneto-abrasive tool on parts being machined during magneto-abrasive machining in conditions of the annular bath with large working gaps
Authors: Maiboroda Victor , Dzhulii Dmytro , Zastavskyi Kostiantyn
Published: September 2023

Background. For effective magneto-abrasive machining (MAM) of complex-shaped parts, comprehensive information is needed on the processes that occur when the magneto-abrasive tool (MAT) contacts with the surfaces being machined. Effective magneto-abrasive machining occurs in the presence of sufficient values of the normal and tangential components of the interaction forces between the MAT and the machined surfaces and the powder mixing during machining. Previously carried out analytical studies of dynamic parameters did not take into account the real conditions of the interaction of grains and their groups with machined surfaces.
Objective. Complex analysis of the processes that occur during magneto-abrasive machining of parts made from different types of materials, based on the results of the study of the friction forces between the magneto-abrasive tool and the surface being machined and the drag forces during the movement of parts in the working zone of the machine.
Methods. To achieve the set goal, the forces acting on the samples during their magneto-abrasive machining were measured with subsequent analytical analysis.
Results. The complex analysis of the processes occurring during MAM in conditions of the annular working zone with large working gaps of parts made of various materials was carried out based on the results of the study of the friction and drag forces that occur when the part moves relative to the magneto-abrasive tool.
Conclusions. It has been determined that when machining non-magnetic samples at the constant value of the magnetic field in the working zone, the specific drag forces are practically independent of the shape of the used powder. According to the analytical representation of the friction and drag forces, their ratio between their specific values was calculated. By the nature of the change in this ratio, it was found that it decreases with an increase in the velocity of samples movement along the working zone, and with an increase in the angular velocity of rotation of the samples around its axis, this value increases in the studied velocity range. It has been determined that at the velocity of movement along the working zone of 2.2 m/s, there is a slight increase in the ratio between the specific forces of friction and drag, which is associated with the action of ponderomotive forces that appear near the surface of the machined parts and lead to an increase in local magnetic forces in these zones.

Authors: Strelenko Nataliya , Kovalenko Vladyslav , Mastenko Roman
Published: September 2023

The relevance of using slag crust separation methods, which are characterized by easy separation and are based on thermo-deformation processes in the sample, is shown in the development of new welding materials. The developed method of assessing slag separation based on the theoretical calculation of thermo-deformation processes in the base metal has passed the stages of experimental research The experimental approbation of the proposed methodology for assessing the separation of the slag coating from the surface of welded joints under experimental fluxes based on the TiO2-MnO-SiO2–MgO–CaO-FeO-Al2O3 slag system was carried out for different welding regimes. The evaluation criterion for the high-temperature separation of the slag coating takes into account: the ratio of the geometric parameters of the test sample, the amount of heat input during the surfacing process, and the factor of the presence of spinel-forming components at the slag-metal interface. The selected parameters for evaluating the separation of the slag crust in points, where the guaranteed separation of the slag coating is counted for the arbitrary separation of the slag during its destruction or the arbitrary separation of the slag by a monolithic layer. The practical value of the proposed method lies in the possibility of quantitative assessment of the probability of high-temperature separation of the slag coating for a wide range of fluxes for surfacing.
The results of the conducted experiments show the efficiency of the developed methodology for evaluating the high-temperature separation of the slag coating from the surface of the weld metal.

System construction of cybersecurity vulnerabilities with Q-analysis
Authors: Polutsyhanova Viktoriia Igorivna
Published: September 2023

Today, in order to assess potential cyber threats, it is necessary to conduct a comprehensive assessment of the vulnerabilities of the investigated system. To do this, it is necessary to describe the identified vulnerabilities and consider potential vulnerabilities. In addition, the relationship between system vulnerabilities must be properly assessed. The most common assumption is that all vulnerabilities are independent and are implemented either by random events or by malicious intent. The paper proposes a method that allows modeling the vulnerabilities of complex systems as a whole, taking into account their hidden connections. Q-analysis [2] was used to study the structure of the system of interconnected vulnerabilities that arise in the process of project implementation. An example of the application of Q-analysis methods is presented and an explanation of the nature and impact of some potential threats and their combinations is offered.

Published: September 2023

In the work, a cyber security logical and probabilistic model of a critical infrastructure facility in the energy sector was developed and investigated. The cyber security logical and probabilistic model describes the development of adverse events that arise in the Industrial Control System of the electrical network from the realization of possible threats from cyberspace, such as attacks on the protection system through the corporate network, connection through a modem and wireless connection. The resulting model is based on sequentially developed structural, logical and probabilistic models.

The field of use of the developed model is automation systems for designing information protection systems or designing trajectories of attacks on these systems. The model was also applied to study the sensitivity of the probability of the development of adverse events to variations in the probability of realization of possible threats to the system.

Published: September 2023

Alliances are common in the world history. In the framework of international relations, several theoretical explanations were applied to answer the questions of why and how states enter into alliances. The traditional approach explains the concept of alliance through the assumptions of the theory of balance of power. Game theory is also a theoretical approach to analyze the behavior of states used in academic and strategic analysis. In this paper, the basic assumption about the behavior of the states of the collective West is the theory of balance of threat. In the geographical sense, the subject of analysis is Eastern and South-Eastern Europe as a response to the behavior of the states. When faced with a significant external threat, states can balance or join. Balancing is defined as an alliance with other states against a current threat; the association is brought to the association with the source of danger. This theory is presented through an analysis of state decisions on critical issues in the international security depending on whether states balance or join by Stephen Walt, systematically exposed in the capital work The Origin of Alliances. (Волт, 2009) In this paper, the subject of analysis is the expansion of the NATO pact after the end of the Cold War, trying to give answers to the question of why the countries of Central, Eastern and South-Eastern Europe "joined" this military alliance after the fall of the "Iron Curtain". Keywords: alliance; balance; international security; Russian Federation
THE ROLE OF THE POLICE OF MONTENEGRO IN COMBATING FAN HOOLIGANISM
Authors:   University of Criminal Investigation and Police Studies, Belgrade, Serbia, Janković Bojan , Cvetkovic Vladimir , Ivanov Aleksandar
Published: September 2023

In recent years, hooligan incidents in Montenegro have become more frequent and violent. Hooliganism at sports events is becoming recognized as a serious problem by citizens, legislators, and other state institutions. Violence at sports events in Montenegro exists, but it still does not represent a major security problem. States deal with this security problem in different ways, primarily by passing appropriate regulations, but in solving this problem in all states, the police seem to play a primary role. In recent years, we have witnessed a proactive approach by the police to this problem. This is precisely where the lack of the Montenegrin police, which has good police units that act repressively on hooligan outbursts, can be seen. However, the Montenegrin police do not have narrowly specialized units dealing exclusively with this problem, which will collect and exchange information about hooligans, as well as the National Office for the Exchange of Information on the Security of Football Competitions (NFIP), which is a prerequisite for the establishment and successful international cooperation in this field. The research presented and analyzed statistical data in the period 2018-2021, which refers to the actions of the Montenegrin police during the security of public gatherings, especially sports events. Based on them, it can be concluded that the Montenegrin police play a significant role in opposing fan hooliganism. Members of the police in Montenegro are adequately prepared to oppose fan hooliganism, as far as repressive actions are concerned. All of the above instills confidence in citizens that the police of Montenegro will succeed, together with other state bodies, in adequately opposing fan hooliganism.
STRUCTURAL SOCIAL FACTORS AND THEIR RELATIONSHIP WITH HOMELESSNESS
Authors:   Faculty of security - Skopje, Stefanovska Vesna
Published: September 2023

In order to understand and explain criminal, deviant and other social problems as complex phenomena in the society, we need to investigate and perceive their causality, development, dynamics and duration. They can be observed as an individual phenomenon, which means analyzing homeless people as indiviuals, but also as complex social phenomena that have their own scope, dynamics, structure, occurrence, which are socially dangerous, in contradiction with the system of values in a society and cause negative consequences. In that context, homelessness as a public, social, and health problem can be considered as an individual human condition. Or as a negative phenomenon that exists in the society, there is a need to analyze the deep structural factors and root causes that lead to homelessness. Those are inequality, unequal access to public social services, uneven distribution of wealth, inadequate housing policies, especially social housing and adverse housing loans and benefits. This paper makes some theoretical review of both structural factors that cause and maintain homelessness and certain theoretical approaches which give explanation about the emergence and perception of homelessness.
CRIMINAL POLICY PROTECTION WITHIN SMART CITIES’ AREAS
Authors:   Faculty of Law , University of Niš, Serbia, Kostić Miomira
Published: September 2023

The term smart city was first used in the nineties of the 20th century, and then the focus was on the application of innovative technologies, as part of modern infrastructure within cities. Nowadays, a smart city means an instrumented, interconnected and intelligent city. European cities are not sufficiently tolerable, inclusive or productive for the needs of the modern age. Smart cities of the present and future should improve the area of social life, but also the organization of public transport, for example. In addition, the policy of developing smart cities should prevent difficulties, rather than finding ways to solve them. The aging of the European population, the integration of migrants, social exclusion or the unsustainability of the natural environment, as well as unemployment, delinquency and a weak local economy, are seen as pressing difficulties. Human or social ecology describes the relationships between people who share the same habitat or local territory and these relationships are clearly related to the character of the territory itself. It is, in fact, learning about social structure in relation to the local environment. So sociologists, in the later years of the 20th century, included ecology in studies of social development or the evolution of human institutions and widely incorporated that concept from the domain of natural sciences into the domain of social sciences. The development of smart cities, by itself, will not eliminate delinquency. Therefore, it is necessary to consider a special concept of crime prevention, which would primarily refer to the prevention of criminal behavior within the community, within the city.
COMPETENCES OF THE COMMISSION FOR DEFENSE AND SECURITY OF THE PARLIAMENT OF THE REPUBLIC OF NORTH MACEDONIA AS A FACTOR OF THE SECURITY OF THE COUNTRY
Authors: Arsikj Davor , Abdulan Pulumb
Published: September 2023

In the composition of the Parliament of the Republic of North Macedonia, there are three commissions that are responsible for different areas and are directly related to security: the most important one: The Commission for Defense and Security, as well as the Commission for Supervision over the work of the National Security Agency and the Intelligence Agency and lastly, Commission for supervision over the implementation of communications monitoring measures. The constitutional power possessed by the Parliament, as well as its role in the improvement of laws during the parliamentary procedure, is the main factor with which significant changes can be made, which would have a positive impact on the regulation of the area of security. Experts would make an additional positive contribution here, especially those who gained their experience outside the country and who would pass their positive experiences to us. We should not overlook the fact that the more developed countries have invested much more than us in the field of security, especially the EU member states that mutually exchange experiences and knowledge and when it comes to security act as one entity composed of a large number of experts. Looking at the current geopolitical movements, maintaining security in the future will be a challenge, especially for the weaker countries, which can be the target of various means that would violate their general security and thus the trust of the citizens towards the institutions. The often-emphasized meritocracy rather than partocracy as well as giving opportunity to distinguished experts and zero tolerance for mistakes and failures in the security sector would be key to success. It should be taken into consideration that positive results do not come in an instant, but security threats can come at any moment.

Published: September 2023

On the example of the most common in the use of diesel engines of commercial vehicles, the requirements for environmental and economic indicators, their evolutionary development over the past decades and, accordingly, changes in the impact on the environment and in the consumption of natural resources are considered. Road transport in terms of traffic significantly exceeds all other modes of transport, is the main consumer of scarce hydrocarbon oil fuels; and is considered the most significant pollutant of the surrounding atmosphere with toxic substances contained in the exhaust gases of engines.
In recent years, during the development, implementation in production and use in operation, there have been significant changes in the design, technology, manufacturing, organization of the workflow, improvement of diesel engine systems that provide fuel and air supply, purification of exhaust gases from harmful emissions into the environment. The analysis of changes in requirements, the level of achieved economic and environmental performance of diesel engines of trucks, was carried out using the fuel-environmental criterion. The calculation data and the generalization of the results of the study made it possible to determine changes in the cost of fuel and compensation for environmental damage from the harmful effects of engine exhaust gases on the environment, related to a unit of power in operation, the coefficient of relative operating environmental costs, directly fuel-environmental criterion and to give a quantitative assessment of the evolutionary development of diesel engines of trucks. It has been established that the fuel and environmental efficiency of diesel engines of trucks over the past 30 years has increased by 4.17 times, mainly due to the reduction of harmful emissions into the environment with exhaust gases.

Authors: Grytsyuk O.V. , Sulyma O.O.
Published: September 2023

Acquaintance of specialists in the engine-building industry, scientists, teachers, doctoral students, graduate students and students of educational institutions with the almost 100-year history of teaching the discipline "Testing of internal combustion engines" was continued. The realities of the current years of teaching this discipline in the conditions of a full-scale military invasion of the Russian Federation into Ukraine by scientific and pedagogical workers who moved to another region of the country from their place of permanent residence and continue to work in the former institution of higher education are described. The experience of organizing online classes in synchronous mode regarding the distance course-resource "DVZ Testing" on the educational website of the National Academy of Sciences was shared. It is shown that the main criterion for evaluating any internal combustion engine development aimed at increasing the efficiency, energy or environmental qualities of engines is testing. At the same time, it is of great importance to organize the educational process in higher education in a distance form, and especially during the period of martial law, with the definition of a platform for conducting classes and ensuring the comprehensive use of available technical means of communication, Internet sites, messengers and existing applications to operating systems. It has been demonstrated that in case of any unexpected power outages, uninterrupted distance learning is guaranteed with the rational use of a backup autonomous generator, a portable charging station, and a power bank. At the same time, special attention should be paid to the selection and adjustment of the connection chains of the component elements to the created power supply system

The use of a system of thermal preparation of a transport engine based on a thermal battery of a phase transition allows to significantly reduce fuel consumption and emissions of harmful substances. At the same time, the use of thermal training systems for vehicles running on gasoline and liquefied petroleum gas, and the evaluation of fuel consumption and emissions of harmful substances in operating conditions were not carried out. The article examines the peculiarities of the method of determining fuel consumption and emissions of harmful substances of engines of vehicles with gasoline and gas supply systems, which are equipped with a thermal preparation system with a phase transition thermal accumulator. The analysis of methods for estimating fuel consumption and emissions of harmful substances of engines, taking into account the formation in the operating conditions of thermal preparation, was performed. An algorithm for determining and evaluating individual criteria for ensuring the thermal preparation of a transport engine in operating conditions has been developed. The method of calculating fuel consumption and emissions of harmful substances in the exhaust gases of vehicles with engines converted to work on gas fuel, equipped with a phase transition heat accumulator, specifically in the processes of pre-startup and post-startup thermal preparation, has been improved. As a result of the implementation of the developed method for determining the fuel consumption and emissions of harmful substances of vehicle engines with gasoline and gas supply systems, the possibility of determining a significant reduction in the operating conditions of the time parameters of the thermal preparation (warm-up) of the vehicle engine and reducing the fuel consumption (gasoline / gas) for warm-up was confirmed.

Kicking the Ladder or Not? Unraveling Income Inequality Perceptions in the World
Authors: ERDÖLEK KOZAL Özge , GÜREL GÜNAL Gülçin
Published: September 2023

This research aims to explore the factors influencing support for income equality at both the individual and macro levels worldwide. By analyzing the latest data from the World Values Survey, which includes responses from 50,615 individuals across 42 countries, and incorporating key macroeconomic variables obtained from the World Bank, this study identifies several crucial determinants of attitudes towards addressing income inequality using logistic regression analysis. The research findings reveal that factors such as material well-being, life satisfaction, institutional trust, job status, place of residence, level of education, and religiosity play a significant role in shaping individual perceptions of income inequality, particularly in the context of support for either support for redistributive policy or free-market capitalism as potential solutions to mitigate income disparities. Additionally, macro-level variables reveal a substantial influence on support for income equality. Income per capita, income share of the top 10, the unemployment rate, and women's representation in parliament as a proxy for gender equality are found to significantly increase the likelihood of endorsing efforts to reduce income inequality. Our results remain robust when controlling for alternative income-related variables.

Published: September 2023

Governments worldwide conceive financial education as a crucial tool for enhancing the financial well-being of families. However, the relationship between financial knowledge and financial behaviors remains inconclusive, particularly in developing countries where a limited number of studies have explored this connection. This study employed a subjective and an objective measure of financial knowledge and assessed 16 financial behaviors of participants from Argentina, Colombia, Ecuador, Mexico, and Peru. Out of these 16 financial behaviors, 14 have a relationship with at least one of the two measures. This study found positive correlations between financial knowledge and various financial behaviors, including planning behaviors, acquisition of formal financial products, willingness to assume risks, seeking financial advice, and cautious management of their financial products. The relationship between the acquisition of informal financial products was positive with the objective financial knowledge measure but negative with the subjective measure. The identification of causal relationships proved challenging and often yield inconclusive results due to identified endogeneity issues and the presence of weak instruments. In general, during the COVID-19 period, participant displayed increased prudency in their financial practices and managing their products. This effect was larger among participants with higher levels of financial knowledge. Future research in Latin America should incorporate the distinction between financial literacy and financial knowledge, explore qualitative research designs, and evaluate the effectiveness of financial educational programs.

Authors: Ahmed-Chowdhury Saquib , Ahmad Sohail , Sarker Md. Moklesur Rahman , Ismail Nahlah Elkudssiah
Published: September 2023

Objective: Suboptimal asthma control among patients is associated with psychosocial factors, including depression and stigma, hindering effective asthma management. This study aims to assess depressive symptoms and internalized stigma among adult asthma patients while investigating their relationships with sociodemographic and asthma-related medical factors.
Methods: In this cross-sectional study, 325 adult asthma patients (aged > 18 years old) were recruited from the National Asthma Centre in Dhaka, Bangladesh, using a researcher-administered questionnaire and convenience sampling. The questionnaire included sections on sociodemographic characteristics, medical data, the 9-item Patient Health Questionnaire (PHQ-9) to assess depressive symptoms, and a 22-item stigma scale to assess internalized stigma. Data were analyzed using descriptive and inferential statistics.
Results: The majority of participants were aged 18-40 years (54.2%), male (53.5%), from rural areas (50.8%), with a monthly family income of 5 years (46.5%). The mean PHQ-9 score was 7.36 (±6), indicating mild depressive symptoms, and the internalized stigma score was 62.2 (±10.26), indicating moderate internalized stigma. Depression and stigma varied significantly across several factors, including age, education, ED visits, hospitalizations for asthma, number of asthma medicines, home nebulizer use, PEF rate, BMI, comorbidities, and asthma symptom control (p<0.05). Stigma was correlated with depression and negatively correlated with age and years since asthma diagnosis (p<0.01).
Conclusion: This study highlights associations between depressive symptoms, internalized stigma, and various sociodemographic and medical factors among asthma patients. Notably, stigma was higher among younger adults and recently diagnosed patients. Effective interventions are needed to mitigate stigma and depression in this patient population.

Published: September 2023

Background
Influenza is a common illness for its high rates of morbidity and transmission. The implementation of non-pharmaceutical interventions (NPIs) during the COVID-19 pandemic to manage its dissemination could affect the transmission of influenza.
Methods
A retrospective analysis, between 2018 and 2023, was conducted to examine the incidence of influenza virus types A and B among patients in sentinel cities located in North or South China as well as in Wuhan City. For validations, data on the total count of influenza patients from 2018 to 2023 were collected at the Central Hospital of Wuhan, which is not included in the sentinel hospital network. Time series methods were utilized to examine seasonal patterns and to forecast future influenza trends.
Results
Northern and southern cities in China had earlier outbreaks during the NPIs period by about 8 weeks compared to the 2018-2019. The implementation of NPIs significantly reduced the influenza-like illness (ILI) rate and infection durations. Influenza B Victoria and H3N2 were the first circulating strains detected after the relaxation of NPIs, followed by H1N1 across mainland China. The SARIMA model predicted synchronized H1N1 outbreak cycles in North and South China, with H3N2 expected to occur in the summer in southern cities and in the winter in northern cities over the next 3 years. The ILI burden is expected to rise in both North and South China over the next 3 years, with higher ILI% levels in southern cities throughout the year, especially in winter, and in northern cities mainly during winter. In Wuhan City and the Central Hospital of Wuhan, influenza levels are projected to peak in the winter of 2024, with 2 smaller peaks expected during the summer of 2023.
Conclusions
In this study, we report the impact of NPIs on future influenza trends in mainland China. We recommend that local governments encourage vaccination during the transition period between summer and winter to mitigate economic losses and mortality associated with influenza.
Ancestry-attenuated effects of socioeconomic deprivation on type 2 diabetes disparities in the All of Us cohort
Authors: Lam Vincent , Sharma Shivam , Gupta Sonali , Spouge John L. , Jordan I. King , Mariño-Ramírez Leonardo
Published: September 2023

Background: Diabetes is a common disease with a major burden on morbidity, mortality, and productivity. Type 2 diabetes (T2D) accounts for roughly 90% of all diabetes cases in the United States and has greater observed prevalence among those who identify as Black or Hispanic.
Methods: The aims of this study were to determine whether T2D racial and ethnic disparities can be observed in data from the All of Us Research Program and to measure associations of genetic ancestry (GA) and socioeconomic deprivation with T2D. The All of UsResearcher Workbench was used to calculate T2D prevalence and to model T2D associations with GA, individual-level (iSDI) and zip code-based (zSDI) socioeconomic deprivation indices within and between participant self-identified race and ethnicity (SIRE) groups.
Results: The study cohort of 86,488 participants from the four largest SIRE groups in All of Us: Asian (n=2,311), Black (n=16,282), Hispanic (n=16,966), and White (n=50,292). SIRE groups show characteristic genetic ancestry patterns, consistent with their diverse origins, together with a continuum of ancestry fractions within and between groups. The Black and Hispanic groups show the highest median SDI values, followed by the Asian and White groups. Black participants show the highest age- and sex-adjusted T2D prevalence (21.9%), followed by the Hispanic (19.9%), Asian (15.1%), and White (14.8%) groups. Minority SIRE groups and socioeconomic deprivation are positively associated with T2D, when the entire cohort is analyzed together. However, SIRE and GA both show negative interaction effects with SDI on T2D. Higher levels of SDI are negatively associated with T2D in the Black and Hispanic groups, and higher levels of SDI are negatively associated with T2D at high levels of African and Native American ancestry.
Conclusion: Socioeconomic deprivation is positively associated with the SIRE group T2D disparities observed here but negatively associated with T2D within the Black and Hispanic groups that show the highest T2D prevalence. These results are paradoxical and have not been reported elsewhere. We discuss possible explanations for this paradox related to the nature of the All of Us data along with SIRE group differences in access to healthcare, diet, and lifestyle.
Multiobjective Operation Optimization of Reheating Furnace based on Data Analytics
Authors: Ban Yunqi , Wang Xianpeng , Zhao Guodong , Wu Jian
Published: September 2023

Reheating furnace consumes a large amount of energy in the hot rolling stage of steel production, and has a significant impact on the product quality of hot rolling. To guarantee the stability of product quality, the operation optimization model of the reheating furnace is established. The operation optimization model aims to achieve optimal heating temperature settings for different slab specifications and different element contents, so that slab heating quality, heating temperature setting and slab heating time can be optimized simultaneously. To address this problem, an improved MOEA/D-DQN algorithm is developed according to the defined state and reward, in which the adaptive selection of differential mutation operators based on reinforcement learning is proposed to improve the search ability and robustness of the algorithm. Based on benchmark and practice, the experimental results show that MOEA/D-DQN algorithm can effectively solve the operation optimization problem of heating furnace.

Published: September 2023

Bovine mastitis is one of the main inflammatory diseases that can affect the udder during lactation. Somatic cell count and sometimes microbiological tests are routinely adopted during monitoring diagnostics in dairy herds. However, subclinical mastitis is challenging to be identified, reducing the possibilities of early treatments. The main aim of this study was to investigate the miRNome profile of extracellular vesicles isolated in milk as potential biomarkers of subclinical mastitis. Milk samples were collected from a total of 60 dairy cows during routine monitoring tests. Therefore, a smallRNA-sequencing technology was applied to extracellular vesicles of milk samples collected from cows classified according to the somatic cell count, in order to identify differences in the miRNome between mastitic and healthy cows. A total of 1,997 miRNAs were differentially expressed between groups. Among them, 68 miRNAs were obtained with FDR < 0.05, mostly downregulated and with only one upregulated miRNA (i.e., miR-361). Functional analysis revealed that miR-455-3p, miR-503-3p, miR-1301-3p and miR-361-5p were involved in the regulation of several biological processes related to mastitis, including immune system related processes. This study confirmed a strong involvement of extracellular vesicles-derived miRNAs in the regulation of mastitis. Moreover, it provides evidence that miRNA from milk extracellular vesicles can be used to identify biomarkers of mastitis. However, further studies must be conducted to validate those miRNAs, especially for subclinical diagnosis.
A Multi-Encoder Model for Automatic Code Comment Generation

Published: September 2023

Automatic code comment generation is an important research topic in software engineering, which aims to help developers understand the source code. However, this task is challenging due to the issues of long dependencies, source code structure information, and out-of-vocabulary (OOV) words. In this paper, we propose HCCM, a novel neural network model that uses three encoders to generate natural language comments for Java methods. The proposed model incorporates three novel techniques: (1) the S-SBT method to encode the abstract syntax tree of the source code; (2) a pointer generation network to copy OOV words from the source code; and (3) a convolutional neural network to capture local features of the source code tokens. We evaluate our model on a state-of-the-art large-scale Java dataset and show that it outperforms the existing methods on several metrics such as BLEU, METEOR, and ROUGE.

Posttransplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis has been increasingly used in HLA-haploidentical transplantation and recent studies also demonstrated the efficacy of PTCy in HLA-matched transplantation. However, data on PTCy in HLA 1–2 allele mismatched transplants are limited. We conducted a prospective multicenter phase II study to evaluate the safety and efficacy of PTCy with tacrolimus and mycophenolate mofetil in 43 patients who underwent HLA-matched (n = 21) or HLA 1–2 allele mismatched (n = 22) peripheral blood stem cell transplantation (PBSCT) following myeloablative (n = 28) or reduced-intensity (n = 15) conditioning. The incidence of grade III-IV acute GVHD at 100 days was 2.3%. The incidences of grades II-IV acute GVHD, all grade chronic GVHD, and moderate to severe chronic GVHD at 2 years were 16.3%, 14.0%, and 4.7%, respectively. Overall survival, disease-free survival, and non-relapse mortality at 2 years were 75.3%, 74.0%, and 7.0%, respectively. GVHD-free, relapse-free survival at 2 years was 67.0%. The rate of off-immunosuppressants in patients who survived without relapse at 2 years was 85.4%. These results indicate that PTCy is a valid option for GVHD prophylaxis in both HLA-matched and HLA 1–2 allele mismatched PBSCT.

Synergizing the reduction of air pollutants and carbon emissions (APCE) has become a critical tactic alternative to address the issue of climate change. Taking the Yangtze River Delta (YRD) region of China as a case study, this paper explores the spatial and temporal distribution pattern of the coupling coordination degree (CCD) of combating APCE from 2011 to 2022, analyzes the dynamic change in CCD using the convergence test, and investigates the key factors affecting CCD via the Tobit regression model. The results show that: (1) from 2011 to 2022, the air pollutants (AP) and CO2 emission (CE) in the YRD region decrease at the annual rate of 10.32% and 0.85%, respectively; (2) the CCD of reducing APCE in the YRD presents a W-shaped fluctuation before 2016 and then steps into a steady increase status after 2016; (3) the order of CCD in four provincial-level units by 2022 is Shanghai>Zhejiang>Jiangsu>Anhui. The proportion of cities where the CCD of reducing APCE enters the high-coordination period has reached 87.8%; (4) the Tobit regression results affirm that economic growth, industrial structure, and green technological innovation exacerbate the CCD of combating APCE, while opening-up level mitigates it. Therefore, it is recommended that the YRD region prioritize facilitating green technology innovation in economic development and increase the competitive advantage amid international trade.

Published: September 2023

• Background
Chronic insomnia is the most prevalent sleep disorder among military service members, and it compromises readiness, performance, and physical and mental health. Cognitive Behavioral Treatment for Insomnia (CBTI) is the standard of care for the treatment of insomnia recommended by the VA/DoD Clinical Practice Guideline, the American Academy of Sleep Medicine, and the American College of Physicians. CBTI is highly effective but has limited scalability. It is often unavailable in clinical settings where service members receive sleep care. Digital technologies offer unique opportunities to scale and broaden the geographic reach of CBTI services and support increased patient access and engagement in behavioral sleep care. This study aims to evaluate the impact and acceptability of digital CBTI hubs to augment military treatment facilities’ capabilities in behavioral sleep medicine.
• Methods
This is a multi-site, non-inferiority randomized clinical trial designed to compare the effects of in-person (face-to-face or virtual) insomnia care as usual at three military sleep clinics versus CBTI delivered remotely and asynchronously through digital CBTI hubs. Digital CBTI hubs are led by licensed, certified clinicians who use NOCTEM’s® evidence-based clinical decision support platform COAST™ (Clinician Operated Assistive Sleep Technology). Changes in insomnia severity and daytime symptoms of depression and anxiety will be compared at baseline, at 6–8 weeks, and at 3-month follow-up. Patient satisfaction with insomnia care as usual versus digital CBTI hubs will also be examined. We hypothesize that digital CBTI hubs will be non-inferior to insomnia care as usual for improvements in insomnia and daytime symptoms as well as patient satisfaction with insomnia care.
• Discussion
Digital technology has a high potential to scale CBTI accessibility and delivery options required to meet the insomnia care needs of military service members. Digital CBTI hubs using COAST offers a novel approach to broaden service members' access to CBTI and to serve as an augmentation strategy for existing sleep services at military treatment facilities. The pragmatic approach leveraging technology in this trial has the potential to rapidly inform clinical practice within the Defense Health Agency as well as other healthcare systems.
