Incremental IoT for industrial maintenance using the legacy culture
Authors: Duque Flavio Augusto R. S. , Goulart Lucas F. , Silva Adelti Assis , Cesar Cecilia A. Castro 
Published: April 2023

AbstractCurrently, the Internet of Things (IoT) technology offers a portfolio of solutions for predictive maintenance and promises problem‐solving. However, there is no systematic strategy for legacy systems capable of taking advantage of the knowledge of the company's culture and simultaneously enabling the incremental deployment of IoT. This article proposes an expansion of the Ignite Systems Development Methodology introduced by Bosch. The proposed methodology is focused on the Maintenance task and incorporates concepts rooted in the industry, such as OEE, FMEA, and CBM. We tested the Methodology through a case study, and the result was a significant reduction in downtime.
Modelica‐AeroDyn: Development, benchmark, and application of a comprehensive object‐oriented tool for dynamic analysis of non‐conventional horizontal‐axis floating wind turbines
Authors: El Beshbichi Omar , Xing Yihan , Chen Ong Muk 
Published: April 2023

AbstractThe exploitation of offshore wind energy by means of floating wind turbines is gaining traction as a suitable option to produce sustainable energy. Multi‐rotor floating wind turbines have been proposed as an appealing option to reduce the costs associated with manufacturing, logistics, offshore installations, and operation and maintenance of large wind turbine components. The development of such systems is forestalled by the lack of a dedicated tool for dynamics and load analysis. Standard codes, such as FAST by NREL, offer the desired fidelity level but are not able to accommodate multi‐rotor configurations. A few experimental codes have been also proposed, which may accommodate multi‐rotor systems, but low flexibility makes them impractical to study a vast range of innovative multi‐rotor FWTs concepts. To close the gap, this work presents the development and comprehensive benchmark of a fully coupled aero‐hydro‐servo‐elastic tool able to easily accommodate arbitrary platform and tower geometries and the number of wind turbines employed. Development is carried out in Modelica, which allows for the employment of the same code functionality in a virtually unlimited number of physical configurations. Full blade‐element momentum capabilities are achieved by integrating into Modelica the well‐established NREL aerodynamic module AeroDyn v15 within FAST v8. Structural dynamics of tower and blades are implemented through a lumped‐element approach. Hydrodynamic loads are computed by employing the DNV software SESAM WADAM. Thorough benchmark is performed against FAST, and positive results are obtained. The dynamic performance of a two‐rotor floating wind turbine is finally assessed considering different turbulence spectrums.
Stability of thermoelastic diffusion problem of type III in spaces of different dimensions
Authors: Aouadi Moncef , Passarella Francesca , Tibullo Vincenzo 
Published: April 2023

AbstractIn this article, we study the stability issues of a thermoelastic diffusion problem of type III in spaces of different dimensions. First we prove that the one‐dimensional problem is exponentially stable without adding damping terms. Then we prove the lack of exponential stability in the two‐dimensional space. Moreover, a frictional damping for the elastic component leads to the exponential stability in three‐dimensional space. As the form of the damping term depends on the nature of the material, we will distinguish the case of isotropic materials and the case of anisotropic materials.
Nuclear Waste Governance in Italy: Between Participation Rhetoric and Regionalism
Authors: Di Nucci Maria Rosaria , Prontera Andrea 
Published: April 2023

AbstractItaly has abandoned its nuclear power ambitions in the aftermath of the Chernobyl disaster and following the decision of the popular referendum held on 8 November 1987. However, nuclear waste from four permanently shut down nuclear plants, various research reactors, reprocessing and fuel fabrication facilities represents a pressing problem. The nuclear waste governance in Italy is characterised by a complex, intertwined relationship and interaction between the different political-territorial levels from the national, the regional to the local. Recently, after a long period of incoherent stop and go nuclear research and industrial policies, local opposition and a subsequent deadlock, the mandatory search for a national site has started taking shape. The national map of potentially suitable area released in 2021 was followed by a series of consultations to which several institutional and civil society actors participated. In January 2022, the public consultation was concluded and in March 2022 the proposed National Map of Suitable Areas (NACI) was submitted to the Ministry of Ecological Transition for approval. The final site search process should lead to the location of a site, which should initially house 78,000 cubic metres of intermediate and low-level waste as well as 17,000 cubic metres of HLW. The latter should be stored for a maximum of 50 years to be then placed in a deep geological repository about which nothing has been revealed at the moment. This challenges institutional actors, like the Ministry of Ecological Transition, the regulator and the operator to adopt inclusive and decentralised forms of decision making. The process is therefore expected to be slow and cumbersome and will require more democratic approaches to nuclear waste management.
Do You Care About High-Level Radioactive Waste and Spent Nuclear Fuel? Opportunities for Co-Constructing an Appropriate Governance-Ecosystem in Belgium
Authors: Bergmans Anne , Fallon Catherine , Cörvers Ron , Parotte Céline 
Published: April 2023

AbstractThis chapter discusses key dimensions for the future of high-level radioactive waste governance (HLW) in Belgium. It highlights elements that a diverse set of stakeholders considered to be of importance for a national public debate, and puts them in the context of the theoretical notion of ‘matter of care’, as developed by Maria Puig De La Bellacassa (2017). Rather than highlight what perspective every type of actor develops, these perspectives are considered as an interrelated collective in which each has its own merits and reasons for existence.Our results show that it will be very difficult to define a one-sided governance approach that covers virtually all dimensions and expectations from all stakeholders in a satisfactory way. Multiple efforts and a mix of initiatives and responsive actions towards new developments will be needed. Approaching this from a perspective of care allows an empathic attitude towards the needs and expectations of all current and future stakeholders in this debate. Caring means assuming that sociotechnical uncertainties will remain, regardless of the preferred long-term option for radioactive waste. Caring is also about allowing real spaces for others who care to express what they care about and how they desire to do so. Caring is not about providing one pre-fixed initial programme, but is about ensuring the waste is being taken care of by means of a collective and open decision-making and governance process.
The Melancholic Lock: High-Level Radioactive Waste Governance in Spain
Authors: Espluga-Trenc Josep , Prades Ana 
Published: April 2023

AbstractThe attempts to find a consistent solution for high-level radioactive waste in Spain illustrates the challenges entailed by inclusive nuclear waste governance in a country with a multi-level governance system, characterised by a complex and intertwined political decision-making process, where the nuclear issue is used instrumentally by political parties, in a social context with highly sceptical public opinion towards nuclear energy. Nuclear waste management in Spain has been influenced by environmental legislation that increasingly requires public transparency and openness to citizen participation, mainly due to the internalisation of European Directives. This has been reflected in the approach to managing the location of the repository for high-level nuclear waste, so far without success due to the structure of the nuclear conflict in Spain, which relegates the role of science and technology to marginal positions in the debate. Instead of a “politicization of nuclear issues”, in Spain, opening the nuclear issue from the closed circles of experts and their organisations to a broad public debate has created a “nuclearization of politics”, leaving limited room for counter-expertise, as nuclear-related arguments are employed opportunistically to serve broader political aims. Since the actors respond to a logic based on the mobilisation of emotions and feelings of grievance in the public sphere, generating trust between actors becomes quite difficult.
Who Decides What is Safe? Experiences from Radioactive Waste Governance in Switzerland
Authors: Kuppler Sophie , Eckhardt Anne , Hocke Peter 
Published: April 2023

AbstractIn Switzerland, the selection procedure for a nuclear waste repository site is characterized by deliberation and debate between different governmental levels, and lay persons and experts. The Swiss democratic model has been adapted in order to allow for direct interaction between the federal authorities and the affected communities. In addition, the rather pragmatic approach to finding solutions to emerging conflicts has contributed to the good progress the site selection procedure has made so far. In this chapter, the authors discuss the basic characteristics of the Swiss approach that have proven helpful so far as well as possible critical issues. They conclude with a discussion on potentials and pitfalls of the future governance ecosystem.
Youth Religiosity and Social Media in Brunei Darussalam
Authors: Mohamad Siti Mazidah 
Published: April 2023

AbstractThe development of digital technology has led to transformations in our everyday lives and, as a result, produced new practices and new spatialities. Young people at the heart of these transformations display unique forms of religiosity that are somewhat different from that of their parents’ generation. This chapter examines young Malay Muslim Bruneians’ lived religiosities in the context of their everyday engagements on social media. They question markers of religiosities, are cautious about self-disclosures, and negotiate and challenge intergenerational and intragenerational pressures. Their lived religiosities offer up microgeographies of young people’s religiosities, and throw new light on contemporary youth religious culture and the broader sociocultural and religious development facilitated by digital technology.
Learning Gender in Malay Muslim Society in Brunei Darussalam
Authors: Shahrin Shariza Wahyuna 
Published: April 2023

AbstractThis chapter explores how Malay primary schoolchildren in Brunei Darussalam understand gender and become gendered. Through ethnographic accounts and data collected from pupils aged from five to 12 years old in a suburban state school, the study demonstrates that children have strict ideas and expectations of what it means to be masculine and feminine, which they inadvertently reinforce and are regulated in their interactions with others. The discussion also deals with children’s associations and dissociations with certain objects in order to understand how they navigate the social world. Besides children, interviews with adults reveal the extent to which masculine and feminine traits are reinforced according to religious and social expectations. The analysis provides insights into children’s understanding of gender, highlights their ideas of what a Brunei Malay person should be, and offers a glimpse of the importance of children as valid informants for anthropological research.

Published: April 2023

AbstractThis chapter is a case study of the everyday lives of Indonesian domestic maids (amah) working in Brunei Darussalam. It gives an account of the lives, hardships and dreams of five Javanese women employed in Malay households. The chapter also reveals the ways in which their roles as domestic maids abroad have altered the dynamics of gender and power relations in their own traditionally patriarchal households back home in Java, albeit by degrees.
Generalized quotients and holographic duals for 5d S-fold SCFTs
Authors: Apruzzi Fabio , Bergman Oren , Kim Hee-Cheol , Uhlemann Christoph F. 
Published: April 2023

Abstract
ℤn S-folds of 5d SCFTs, including TN, which lead to brane webs with E6,7,8 7-branes were discussed recently in [1, 2]. We generalize the construction to ‘fractional quotients’, which are based on ℤn actions linking multiple copies of the seed theory and lead to H0,1,2 7-branes. We provide the holographic duals for both classes. This expands the space of explicitly known Type IIB AdS6 solutions by incorporating F-theory 7-branes of type E6,7,8 and H0,1,2, extending previous constructions for O7-planes. We discuss observables including the free energies and link the results to matrix model descriptions.

AbstractRegeneration of smooth muscle cells (SMCs) is vital in vascular remodeling. Sca1+ stem/progenitor cells (SPCs) can generate de novo smooth muscle cells after severe vascular injury during vessel repair and regeneration. However, the underlying mechanisms have not been conclusively determined. Here, we reported that lncRNA Metastasis-associated lung adenocarcinoma transcript 1 (Malat1) was down-regulated in various vascular diseases including arteriovenous fistula, artery injury and atherosclerosis. Using genetic lineage tracing mice and veingraft mice surgery model, we found that suppression of lncRNA Malat1 promoted Sca1+ cells to differentiate into SMCs in vivo, resulting in excess SMC accumulation in neointima and vessel stenosis. Genetic ablation of Sca1+ cells attenuated venous arterialization and impaired vascular structure normalization, and thus, resulting in less Malat1 down-regulation. Single cell sequencing further revealed a fibroblast-like phenotype of Sca1+ SPCs-derived SMCs. Protein array sequencing and in vitro assays revealed that SMC regeneration from Sca1+ SPCs was regulated by Malat1 through miR125a-5p/Stat3 signaling pathway. These findings delineate the critical role of Sca1+ SPCs in vascular remodeling and reveal that lncRNA Malat1 is a key regulator and might serve as a novel biomarker or potential therapeutic target for vascular diseases.
Dumping behaviour of Australian desert ants (Melophorus bagoti) (Hymenoptera:Formicidae)
Authors: Deeti S. , Freas C. , Murray T. , Cheng K. 
Published: April 2023

AbstractThe Central Australian desert antMelophorus bagotimaintains ground-nesting colonies in the semi-desert habitat. These ants manage waste by dumping items outside the nest. To examine this process, we placed organic and non-organic materials that are associated with either low or high pathogenic risk around or into the nest and observed the nest’s response. We found that generally, ants dumped high-pathogenic-risk materials (dead larvae, dead ants of the colony, foraged food, moth, and non-nest cicada exoskeleton) further from the nest than low-pathogenic-risk ones (sand, buffel grass, cookies), with the exception of (organic) larval shells from their own nest, which were also dumped close to the nest. This pattern of dumping suggests that these ants choose their dumping distance based on how spoilable the experimental materials are.
Foreclosures and housing prices: does neighborhood configuration matter?
Authors: Turnbull Geoffrey K. , van der Vlist Arno J. 
Published: April 2023

AbstractThis paper measures the extent to which effects of foreclosures vary across neighborhoods. It offers a simple empirical framework for decomposing the spillover effects on neighboring property prices. Data from Orange County, Florida, reveal that the effects systematically vary across neighborhoods by morphology. The results indicate that older, homogeneous age structure, and non-gated neighborhoods with high vacancy rates are most in jeopardy when foreclosures are present, as these neighborhoods show the greatest neighborhood house price effects.
An investigation into the layer thickness effect on the mechanical properties of additively manufactured polymers: PLA and ABS
Authors: Shergill Kietan , Chen Yao , Bull Steve 
Published: April 2023

Abstract3D-printed artefacts are becoming more common, and the effect of printing parameters on their properties is key to their performance in applications. Although parameters like build orientation and raster direction are well-studied the effect of layer thickness is less well-known. This study determines the influence of layer thickness on the mechanical properties of polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) 3D printed specimens made with fused filament fabrication (FFF). Samples were printed with differing layer thicknesses and tensile tested according to ASTM D638. The study also found that when increasing the layer thickness the mechanical properties of the specimens for both ABS and PLA decreased. When it came to ultimate tensile strength, the effect of layer thickness on PLA was more significant than on ABS. Considering the mechanical properties as well as aspects such as printing time and simplicity of printing, an optimum print setting could be determined. The study found that PLA was more significantly affected by the change in layer thickness compared to ABS.
Identification and estimation of categorical random coefficient models
Authors: Gao Zhan , Pesaran M. Hashem 
Published: April 2023

AbstractThis paper proposes a linear categorical random coefficient model, in which the random coefficients follow parametric categorical distributions. The distributional parameters are identified based on a linear recurrence structure of moments of the random coefficients. A generalized method of moments estimation procedure is proposed, also employed by Peter Schmidt and his coauthors to address heterogeneity in time effects in panel data models. Using Monte Carlo simulations, we find that moments of the random coefficients can be estimated reasonably accurately, but large samples are required for the estimation of the parameters of the underlying categorical distribution. The utility of the proposed estimator is illustrated by estimating the distribution of returns to education in the USA by gender and educational levels. We find that rising heterogeneity between educational groups is mainly due to the increasing returns to education for those with postsecondary education, whereas within-group heterogeneity has been rising mostly in the case of individuals with high school or less education.
DS-HECK: double-lasso estimation of Heckman selection model
Authors: Hirukawa Masayuki , Liu Di , Murtazashvili Irina , Prokhorov Artem 
Published: April 2023

AbstractWe extend the Heckman (1979) sample selection model by allowing for a large number of controls that are selected using lasso under a sparsity scenario. The standard lasso estimation is known to under-select causing an omitted variable bias in addition to the sample selection bias. We outline the required adjustments needed to restore consistency of lasso-based estimation and inference for vector-valued parameters of interest in such models. The adjustments include double lasso for both the selection equation and main equation and a correction of the variance matrix. We also connect the estimator with results on redundancy of moment conditions. We demonstrate the effect of the adjustments using simulations and we investigate the determinants of female labor market participation and earnings in the US using the new approach. The paper comes with , a dedicated Stata command for estimating double-selection Heckman models.
Assessing fiscal multipliers in times of crisis: evidence from selected CEE countries
Authors: Muraraşu Bogdan , Anghelescu Cristina , Grecu Robert Adrian 
Published: April 2023

AbstractThe COVID-19 pandemic proved to be an unprecedented socio-economic crisis in the last decades. More than three years after its outbreak, there is still uncertainty regarding its future evolution. National and international authorities adopted a prompt and synchronized response to limit the adverse effects of the health crisis, in terms of socio-economic damage. Against this background, this paper assesses the efficiency of the measures implemented by fiscal authorities in selected Central and Eastern European countries to ameliorate the economic repercussions of the crisis. The analysis reveals that the impact of expenditure-side measures is stronger than that of revenue-side ones. Additionally, the results of a time-varying parameter model indicate that the fiscal multipliers are higher in times of crisis. In view of the ongoing war in Ukraine, the related geopolitical turmoil and energy crisis, the findings of this paper are especially pertinent, given the need for additional fiscal support.
A Possible Aquatic Origin of the Thiaminase TenA of the Human Gut Symbiont Bacteroides thetaiotaomicron
Authors: Stentz Régis , Cheema Jitender , Philo Mark , Carding Simon R. 
Published: April 2023

AbstractTenA thiamin-degrading enzymes are commonly found in prokaryotes, plants, fungi and algae and are involved in the thiamin salvage pathway. The gut symbiont Bacteroides thetaiotaomicron (Bt) produces a TenA protein (BtTenA) which is packaged into its extracellular vesicles. An alignment of BtTenA protein sequence with proteins from different databases using the basic local alignment search tool (BLAST) and the generation of a phylogenetic tree revealed that BtTenA is related to TenA-like proteins not only found in a small number of intestinal bacterial species but also in some aquatic bacteria, aquatic invertebrates, and freshwater fish. This is, to our knowledge, the first report describing the presence of TenA-encoding genes in the genome of members of the animal kingdom. By searching metagenomic databases of diverse host-associated microbial communities, we found that BtTenA homologues were mostly represented in biofilms present on the surface of macroalgae found in Australian coral reefs. We also confirmed the ability of a recombinant BtTenA to degrade thiamin. Our study shows that BttenA-like genes which encode a novel sub-class of TenA proteins are sparingly distributed across two kingdoms of life, a feature of accessory genes known for their ability to spread between species through horizontal gene transfer.
