Multimodal Imaging of a Culotte Bifurcation Procedure in the Left Main Coronary Artery of a Perfusion-Fixed Human Heart: Step-by-Step with Serial Micro-CT Analyses
Authors: Valenzuela Thomas F. , Iaizzo Paul A. 
Published: March 2023

AbstractPercutaneous coronary intervention can be a high-risk procedure that would benefit from optimizing device-tissue interactions between stents and coronary vessels. Using a perfusion-fixed human heart with coronary artery disease, we performed a percutaneous coronary intervention of the left main coronary artery bifurcation. This heart was perfused and multimodal imaging was utilized to view the procedure with direct visualization, fluoroscopy, and optical coherence tomography (OCT). We followed the European Bifurcation Club’s guidelines to perform a single-stent bifurcation before transitioning to a two-stent Culotte technique. After each procedural step, the heart was removed from the perfusion apparatus and transferred to a micro-CT scanner to obtain unique scans. We conducted apposition analyses of the computational 3D models from micro-CT DICOM datasets, and compared them to the results from direct visualization and commercial OCT’s Apposition Indicator software. Additional measurements of resulting coronary anatomic expansions were taken to determine the potential roles of each step in improving procedural outcomes.

Two-stage optimization scheme of routing scheduling from a single distribution center to multiple customers
Authors: Núñez-Muñoz Matías , Linfati Rodrigo , Escobar John Willmer 
Published: March 2023

AbstractThis paper proposes a solution scheme for the problem of scheduling deliveries from distribution centers. The solution scheme is developed in two phases. The first phase corresponds to the collection and processing of data, and the second phase includes the design of a customer assignment model based on the data of the first phase. The first phase provides the characteristics of the customers, the number of orders to be dispatched, and the number of visited customers. In the second phase, optimization techniques are used, considering scheduling and assignment problem-solving methodologies. The optimization model provides the correct assignment of customer orders to vehicles, reducing the number of trips and the fleet's size and occupation percentage. The proposed solution scheme is developed with a company operating a distribution center responsible for dispatching vehicles to all retail customers, wholesalers, and distributors in the Province of Concepción, Province of Arauco, and Province of Itata in Chile. The obtained results are prominent and show that the proposed methodology can be extended to companies performing storage, transportation, and distribution tasks with similar characteristics.

Published: March 2023

AbstractDriven by the focus on standardised assessment and performance-driven accountability, a considerable body of literature has documented differences in students’ academic achievement across school sectors, both internationally and in Australia. However, few studies have to date explored the potential mechanisms underlying such differences, particularly through the lens of school climate and student engagement. And despite extensive literature on school climate and student engagement, including their relationships with achievement, the differences in these patterns across school sectors remain under-studied. In this paper, we leverage nationally representative data from a large-scale longitudinal survey in Australia with linked administrative data on student achievement to reveal different patterns of school climate and student engagement across government, Catholic and independent sectors. Employing multivariable regression analyses, we identify unique school climate and student engagement facets that are associated with improved achievement in each of these sectors, offering important pointers for educational policies.
Comparison of Tool Wear, Surface Morphology, Specific Cutting Energy and Cutting Temperature in Machining of Titanium Alloys Under Hybrid and Green Cooling Strategies

Published: March 2023

AbstractCutting energy must be reduced in order to make machining processes more eco-friendly. More energy was expended for the same amount of material removed, hence a higher specific cutting energy (SCE) implies inefficient material removal. Usually, the type of coolants or lubricants affects the SCE, or the amount of energy needed to cut a given volume of material. Therefore, the present work deals with a study of SCE in the turning of Ti–3Al–2.5V alloy under green cooling strategies. In spite of this, the research effort is also focused on the mechanism of tool wear, surface roughness, and cutting temperature under hybrid cooling, i.e., minimum quantity lubrication (MQL) and cryogenic. The tool wear rate, were explored with tool mapping analysis, and the results were compared with dry, MQL, and liquid nitrogen (LN2) conditions. The tool wear rate analysis claims that the dry condition causes more built up edge (BUE) formation. In addition, the hybrid cooling conditions are helpful in reducing the SCE while machining titanium alloys.
On the role of social rules in economic development: historical perspectives
Authors: Chavas Jean-Paul 
Published: March 2023

AbstractThis paper explores the role of social rules in economic development. It reviews the historical evidence on social rules and their linkages with human capital. We present supporting evidence from the historical evolution of four important aspects of society: (1) improved dispute resolution mechanisms; (2) the elimination of debt bondage; (3) reductions in the severity of punishments; and (4) the development of limited liability rules and their linkages with the rise of the modern corporation. In each case, we evaluate how social rules have evolved to protect human capital and support economic development.

Published: March 2023

AbstractAdvanced persistent threat (APT) is a serious concern in cyber-security that has matured and grown over the years with the advent of technology. The main aim of this study is to establish an effective identification model for APT attacks to prevent and reduce their influence. Machine learning has the potential as well as substantial background to detect and predict cyber-security threats including APT. This study utilized several boosting-based machine learning methods to predict various types of APTs that are consistent in cyber-security domain. Furthermore, Explainable Artificial Intelligence (XAI) was coupled with the predictions to provide actionable insights to the domain stakeholders as well as practitioners in this domain. The results, particularly XGBoost with weighted F1 score of 0.97 and SHapley Additive exPlanations (SHAP)-based explanation, prove that boosting methods as well as machine learning models paired with XAI are indeed promising in handling cyber-security-related dataset problems which can be extrapolated towards new avenues of challenging research by effectively deploying boosting-based XAI models.
Spatial analysis and optimization of self-pickup points of a new retail model in the Post-Epidemic Era: the case of Community-Group-Buying in Xi’an City

Published: March 2023

AbstractThe Community-Group-Buying Points (CGBPs) flourished during COVID-19, safeguarding the daily lives of community residents in community lockdowns, and continuing to serve as a popular daily shopping channel in the Post-Epidemic Era with its advantages of low price, convenience and neighborhood trust. These CGBPs are allocated on location preferences however spatial distribution is not equal. Therefore, in this study, we used point of interest (POI) data of 2,433 CGBPs to analyze spatial distribution, operation mode and accessibility of CGBPs in Xi’an city, China as well as proposed the location optimization model. The results showed that the CGBPs were spatially distributed as clusters at α = 0.01 (Moran’s I = 0.44). The CGBPs operation mode was divided into preparation, marketing, transportation, and self-pickup. Further CGBPs were mainly operating in the form of joint ventures, and the relying targets presented the characteristic of ‘convenience store-based and multi-type coexistence’. Influenced by urban planning, land use, and cultural relics protection regulations, they showed an elliptic distribution pattern with a small oblateness, and the density showed a low–high-low circular distribution pattern from the Palace of Tang Dynasty outwards. Furthermore, the number of communities, population density, GDP, and housing type were important driving factors of the spatial pattern of CGBPs. Finally, to maximize attendance, it was suggested to add 248 new CGBPs, retain 394 existing CGBPs, and replace the remaining CGBPs with farmers’ markets, mobile vendors, and supermarkets. The findings of this study would be beneficial to CGB companies in increasing the efficiency of self-pick-up facilities, to city planners in improving urban community-life cycle planning, and to policymakers in formulating relevant policies to balance the interests of stakeholders: CGB enterprises, residents, and vendors.
Modeling and parameter identification of verification systems using stochastic configuration networks

Published: March 2023

AbstractThe gas flow verification system with positive pressure sonic nozzle is calling for high requirements on the stability of gas source pressure. It is difficult to guarantee the stagnation cabin pressure be controlled within its targeted range, because of varying boundary conditions. To solve the above problems, this paper presents a modeling method based on mechanism and data-driven for gas flow verification system with the positive pressure sonic nozzle. The stochastic configuration network is used to dynamically identify parameters in the mechanism model. After substituting the identification results into the model, the RMSE of the pressure and temperature in the stagnation cabin obtained from the simulation and the actual data are 1.26 × 104 and 2.64 × 104, respectively. Considering the dead zone of the regulating valve and the replacement of regulating valve in the actual operation, the model is analyzed by disturbance experiment. Experimental results show that the dynamic mathematical model could reflect the changing trend of the pressure in the pressure regulating process and prove its effectiveness.

Abstract
Vaccines are undeniably an important tool for controlling infectious disease outbreaks, and they are the most certain way to end the epidemic risk. This brief report describes the characteristics of coronavirus disease 2019 (COVID-19) deaths among breakthrough and unvaccinated cases hospitalized in Fars province in the south of Iran. This cross-sectional study was performed to compare breakthrough and unvaccinated death cases in Fars, Iran (February 2, to August 19, 2021). Among 444,728 fully vaccinated people, 60,800 breakthrough cases were detected. Thus, 501 died, of which 297 (297/501) cases were hospitalized and compared with the unvaccinated dead group. The median age for breakthrough and unvaccinated cases was estimated 79 and 65 y, respectively. All signs and symptoms of COVID-19 were more frequent in the unvaccinated group. Decreasing O2 saturation (less than 93%) happened more often in the unvaccinated group significantly. Unvaccinated dead patients had significantly shorter hospital stays. These patients received 66.63% Sinopharm, 0.67% Sputnik, 0.67% COVIran Barekat, and 31.99% AstraZeneca vaccines. None of them were health-care staff. Equitable access to safe and effective vaccines is critical to ending the COVID-19 pandemic. As vaccine uptake increases, we observed a decrease in mortality and protection from severe forms of the disease.
Breaking the Televisual Consensus in Chile: Popular Subjectivity and Popular Revolt in the TV SeriesEl reemplazante
Authors: Martin-Cabrera Luis 
Published: March 2023

AbstractThis article presents a cultural analysis of the Chilean TV seriesEl reemplazante(The substitute). The series ran on TVN (National Television of Chile) from 2012 to 2013, and it is currently available on Netflix. The show broke televisual consensus in Chile that made the production of TV series invested in promoting dissenting political viewpoints virtually impossible. As such,El reemplazantecan be conceived as an antecedent of the 2019 social uprising and as an alternative model of critical TV in Chile and Latin America. The article first examines the mediation between the patriarchal and racist model of the superhero teacher and the construction of a popular subjectivity that disrupts said model. It then deals with the hyperrealist aesthetic of the show as a privileged mode of enacting a social critique on TV, and it addresses the representation of the city and its geographies of segregation as a gateway to unpacking the problematic of education in neoliberal Chile. The conclusion reflects on the abrupt cancellation of the show and the limits that the Chilean production model places on TV series with transformative intentions.
Autonomous Weapons and the Right to Self-Defence
Authors: Kleczkowska Agata 
Published: March 2023

AbstractThis article focuses on the application of autonomous weapons (AWs) in defensive systems and, consequently, assesses the conditions of the legality of employing such weapons from the perspective of the right to self-defence. How far may humans exert control over AWs? Are there any legal constraints in using AWs for the purpose of self-defence? How does their use fit into the traditional criteria of self-defence? The article claims that there are no legal grounds to exclude AWs in advance from being employed to exercise the right to self-defence. In general, the legality of their use depends on how they were pre-programmed by humans and whether they were activated under proper circumstances. The article is divided into three parts. The first discusses how human control over AWs affects the legality of their use. Secondly, the article analyses the criteria of necessity and proportionality during the exercise of the right to self-defence in the context of the employment of AWs. Finally, the use of AWs for anticipatory, pre-emptive or preventive self-defence is investigated.
A safety net for all? – Vignette-based assessments of Swedish social assistance over three decades
Authors: Bergmark Åke , Stranz Hugo 
Published: March 2023

Abstract
Swedish welfare is often characterized as comprehensive and generous. Social assistance constitutes the final safety net in the Swedish model. Unlike most other benefits, eligibility and subsidy levels are here subject to extensive means-testing, with eligibility determined by individual caseworkers. In this article, we explore the extent to which eligibility determination and generosity of benefits have changed in social assistance assessments over three decades, relating these to changes in regulations over the same period.
The article presents data from three independent vignette studies conducted in the mid-1990s, mid-2000s and in 2018 respectively. The data consist of assessments of a total of six vignettes, made by individual caseworkers (n=1 337). The results indicate that overall generosity in social assistance has decreased considerably over the last 25 years and that, despite both national and local initiatives to reduce individual variation in assessments, disparities have instead increased.
A Revolutionary's “Stravaganza”: Police and Morality in the Habsburg Empire (1780–1830)
Authors: Himl Pavel 
Published: March 2023

AbstractDuring the era following the Enlightenment, the police became the main institution to oversee the maintenance of public order in many European cities. Their activities also shaped the idea of public order and public morality. The police were important in the context of political change and perceived “threat of revolution” but also in other areas, including the control of movement and residence. From the end of the eighteenth century, criminal codes were changing, and in the Habsburg monarchy, these changes included the definition of a new category of less grave “police delicts.” This study compares police norms and practice in the period of 1790–1830. Using several concrete examples, the author investigates whether the approach of the police and the authorities to moral offenses changed in connection with social and political developments (reaction to revolutions, restoration, changes in the influence of the Church). The aim of the study is to analyze whether the Habsburg police, in an era of more liberal legislation, played a similar restrictive role in the area of moral offenses as they did in controlling political activities.
Nocturnal activity and behaviour of the elusive bushy-tailed opossum (Glironia Venusta)
Authors: Rushford Corrie E. , Glynn Sean 
Published: March 2023

Abstract
The bushy-tailed opossum (Glironia venusta) is a small arboreal marsupial found in the Amazon basin. G. venusta is rarely seen and has few published sightings throughout its range. Videos (N = 79) were obtained from arboreal camera traps located in the Las Piedras Amazon Center near the Las Piedras River (SE Peru) from April 2017 until November 2017. Our new records, the first for the Las Piedras River, demonstrate that the species is nocturnal with activity peaks at 3:00 h and 20:00 h in the hours of complete darkness. The abundance of camera trap footage of such a rarely observed species further demonstrates the effectiveness of arboreal camera trapping to conduct species assessments.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant (B.1.1.529) rapidly replaced Delta (B.1.617.2) to become dominant in England. Our study assessed differences in transmission between Omicron and Delta using two independent data sources and methods. Omicron and Delta cases were identified through genomic sequencing, genotyping and S-gene target failure in England from 5–11 December 2021. Secondary attack rates for named contacts were calculated in household and non-household settings using contact tracing data, while household clustering was identified using national surveillance data. Logistic regression models were applied to control for factors associated with transmission for both methods. For contact tracing data, higher secondary attack rates for Omicron vs. Delta were identified in households (15.0% vs. 10.8%) and non-households (8.2% vs. 3.7%). For both variants, in household settings, onward transmission was reduced from cases and named contacts who had three doses of vaccine compared to two, but this effect was less pronounced for Omicron (adjusted risk ratio, aRR 0.78 and 0.88) than Delta (aRR 0.62 and 0.68). In non-household settings, a similar reduction was observed only in contacts who had three doses vs. two doses for both Delta (aRR 0.51) and Omicron (aRR 0.76). For national surveillance data, the risk of household clustering, was increased 3.5-fold for Omicron compared to Delta (aRR 3.54 (3.29–3.81)). Our study identified increased risk of onward transmission of Omicron, consistent with its successful global displacement of Delta. We identified a reduced effectiveness of vaccination in lowering risk of transmission, a likely contributor for the rapid propagation of Omicron.
Bidirectional relations between altruistic tendency and benign/malicious envy among adolescents: A longitudinal study and weekly diary study
Authors: Xiang Yanhui , Zhou Yue 
Published: March 2023

AbstractAltruism is a prosocial tendency that has developed through long-term evolutionary selection. The present study adopts social comparison and evolutionary psychology theories to examine how benign/malicious envy can affect altruism and how altruism can affect the two types of envy in turn, respectively. In Study 1, 513 adolescents participated in a three-wave longitudinal survey to explore the relationships between dispositional altruistic tendency and dispositional benign/malicious envy. The cross-lagged analysis showed a long-term and stable negative bidirectional relationship between dispositional altruistic tendency and dispositional malicious envy and a short-term positive bidirectional relationship between dispositional altruism and dispositional benign envy. In Study 2, 109 adolescents kept a weekly diary for seven consecutive weeks to record state levels of altruistic tendency and benign/malicious envy in their daily lives. The hierarchical linear model demonstrated that weekly altruistic tendency and weekly benign envy could positively predict each other, and weekly altruistic tendency presented a negative bidirectional relationship with weekly malicious envy. These findings offer an effective way to study the relationship between human behavior and emotions from perspectives of social comparison and evolutionary psychology theories. Meanwhile, it also has practical significance for the harmonious development of society.
CHICHEN ITZA AND ITS ECONOMY AT THE END OF THE CLASSIC PERIOD: TRIBUTE, CENTRALIZED REDISTRIBUTION, AND MARITIME STATIONS
Authors: Cobos Rafael 
Published: March 2023

AbstractStudies of the ancient economy associated with the Classic and Postclassic periods of Maya civilization show that, in order to explain it, the market economy model has been widely used, where economic transactions were carried out in marketplaces. In this type of economy, goods are exchanged based on an agreed value that takes into account supply and demand. However, other types of exchange, such as tribute and centralized redistribution, could have been used in those transactions instead of a market economy. This article analyzes the role that tribute and centralized redistribution may have played during the heyday of Chichen Itza between the tenth and eleventh centuries. This site seems to have used its powerful military supremacy to extract tribute from sites and regions it conquered militarily and politically as they experienced their collapse. In addition, the archaeological evidence suggests that Chichen Itza made political as well as economic alliances in different regions of the Maya Lowlands in order to obtain sumptuous goods. These commodities were used by members of the elite to reinforce the power structure and consolidate social relations among the different individuals who inhabited that community located in northern Yucatan.
