Authors: Campos Camila Fonseca Chaves , de Sá Machado Vanessa Aparecida , Soares Laene Oliveira , Boloy Ronney Arismel Mancebo 
Published: March 2024

AbstractThe study aims to rapidly scale up Hybrid Renewable Energy System (HRES) specifically emphasizing bioenergy generation for isolated rural communities. It aims to identify the most profitable and efficient configuration for HRES biomass-solar in João Pinheiro, taking advantage of local eucalyptus production to reduce costs associated with the transport of biomass waste, considering energy, economic and ecological indicators. Eucalyptus waste was chosen as the source of biomass as fuel, the Downdraft gasifier with air as the gasification agent, and monocrystalline silicon technology was selected for photovoltaic modules. Two case study scenarios were proposed based on global efficiency calculations. The techno-economic analysis was applied based on the First Law of Thermodynamics and the Levelized Cost of Electricity (LCOE) method. Case 2 showed the overall energy efficiency of 17.43% and LCOE 0.034 US$/kWh more suitable for HRES solar-biomass technology. Additionally, the eco-efficiency indicator indicator based on the calculated Net Present Value and ecological efficiency indicator, allowed evaluation of the relationship between added value and the environmental impacts associated with the studied configurations, with case 2 presenting 9.28e−05 kgCO2/US$ as best result. The conclusions show that the techno-economic analysis applied to the HRES syngas-solar, along with the eco-efficiency indicator, presents the viability of decentralized bioenergy supply, particularly in isolated rural communities. This innovative approach encourages sustainable measures to meet energy needs in isolated regions with climatic, environmental and biomass supply conditions like those of João Pinheiro.
Investigating fairness in machine learning-based audio sentiment analysis
Authors: Luitel Sophina , Liu Yang , Anwar Mohd 
Published: March 2024

AbstractAudio sentiment analysis is a growing area of research, however little attention has been paid to the fairness of machine learning models in this field. Whilst the current literature covers research on machine learning models’ reliability and fairness in various demographic groups, fairness in audio sentiment analysis with respect to gender is still an uninvestigated field. To fill this knowledge gap, we conducted experiments aimed at assessing the fairness of machine learning algorithms concerning gender within the context of audio sentiment analysis. In this research, we used 442 audio files of happiness and sadness—representing equal samples of male and female subjects—and generated spectrograms for each file. Then we performed feature extraction using bag-of-visual-words method followed by building classifiers using Random Forest, Support Vector Machines, and K-nearest Neighbors algorithms. We investigated whether the machine learning models for audio sentiment analysis are fair across female and male genders. We found the need for gender-specific models for audio sentiment analysis instead of a gender-agnostic-model. Our results provided three pieces of evidence to back up our claim that gender-specific models demonstrate bias in terms of overall accuracy equality when tested using audio samples representing the other gender, as well as combination of both genders. Furthermore, gender-agnostic-model performs poorly in comparison to gender-specific models in classifying sentiments of both male and female audio samples. These findings emphasize the importance of employing an appropriate gender-specific model for an audio sentiment analysis task to ensure fairness and accuracy. The best performance is achieved when using a female-model (78% accuracy) and a male-model (74% accuracy), significantly outperforming the 66% accuracy of the gender-agnostic model.

Published: March 2024

AbstractA convex geometry is a closure system satisfying the anti-exchange property. This paper, following the work of Adaricheva and Bolat (Discrete Math 342(N3):726–746, 2019) and the Polymath REU 2020 team (Convex geometries representable by at most 5 circles on the plane. arXiv:2008.13077), continues to investigate representations of convex geometries on a 5-element base set. It introduces several properties: the opposite property, nested triangle property, area Q property, and separation property, of convex geometries of circles on a plane, preventing this representation for numerous convex geometries on a 5-element base set. It also demonstrates that all 672 convex geometries on a 5-element base set have a representation by ellipses, as given in the appendix for those without a known representation by circles, and introduces a method of expanding representation with circles by defining unary predicates, shown as colors.
Greenhouse gas control in steel manufacturing: inventory, assurance, and strategic reduction review
Authors: Qian Yibo , Li Yuanzhe , Hao Yu , Yu Tong , Hu Haoqian 
Published: March 2024

AbstractThe global steel industry is integral to the development of modern infrastructure, yet it stands as one of the most significant contributors to greenhouse gas (GHG) emissions worldwide. This dichotomy brings forth the imperative for an in-depth analysis of GHG inventory practices and the pursuit of sustainable production methods. This mini-review paper addresses the current methodologies for GHG accounting within the steel sector, emphasizing the critical role of accurate and transparent emissions data as the basis for effective climate change mitigation strategies. Evaluating the prevalent carbon-intensive blast furnace-basic oxygen furnace (BF-BOF) production route, this paper contrasts traditional practices with innovative reduction initiatives, particularly those aligned with the emergence of green steel. We delve into the advancements in electric arc furnace (EAF) technology, direct reduced iron (DRI) processes utilizing green hydrogen, and the potential of carbon capture, utilization, and storage (CCUS) systems. The analysis extends to a critical examination of the challenges and opportunities these technologies face, including economic viability, scalability, and the readiness of energy infrastructure to support such a transition. Further, this review highlights the significance of verification and validation in reinforcing the credibility of GHG inventories. We scrutinize the materiality of reported emissions in the context of evolving regulatory frameworks and stakeholder expectations, stressing the need for standardized and rigorous assurance practices.

Recent advances in implicit representation-based 3D shape generation
Authors: Sun Jia-Mu , Wu Tong , Gao Lin 
Published: March 2024

AbstractVarious techniques have been developed and introduced to address the pressing need to create three-dimensional (3D) content for advanced applications such as virtual reality and augmented reality. However, the intricate nature of 3D shapes poses a greater challenge to their representation and generation than standard two-dimensional (2D) image data. Different types of representations have been proposed in the literature, including meshes, voxels and implicit functions. Implicit representations have attracted considerable interest from researchers due to the emergence of the radiance field representation, which allows the simultaneous reconstruction of both geometry and appearance. Subsequent work has successfully linked traditional signed distance fields to implicit representations, and more recently the triplane has offered the possibility of generating radiance fields using 2D content generators. Many articles have been published focusing on these particular areas of research. This paper provides a comprehensive analysis of recent studies on implicit representation-based 3D shape generation, classifying these studies based on the representation and generation architecture employed. The attributes of each representation are examined in detail. Potential avenues for future research in this area are also suggested.
The motivation and engagement of student volunteers in volunteerism at the University of Gondar
Authors: Wondimu Habtamu , Admas Getachew 
Published: March 2024

AbstractThis study examines student volunteering at the University of Gondar in Ethiopia, aiming to understand motivation and areas of engagement. Using a mixed research method, data from surveys, in-depth interviews, and key informant interviews were analyzed. The sample included 422 participants selected through probability and non-probability sampling techniques. Quantitative findings reveal that understanding the functions of volunteering motivates students, with a desire for learning experiences and applying their skills being primary motivators. The value function and career enhancement function also contribute to motivation. Survey results indicate that students engage in volunteer activities to enhance their resumes and have a strong belief in the importance of helping others. Notably, 47% of volunteer students focus on social and disability affairs. This study emphasizes the need for careful planning and implementation to encourage student volunteerism and maximize its benefits for all involved parties.
Knowledge-How, Ability, and Linguistic Variance
Authors: Mizumoto Masaharu 
Published: March 2024

Abstract
In this paper, we present results of cross-linguistic studies of Japanese and English knowing how constructions that show radical differences in knowledge-how attributions with large effect sizes. The results suggest that the relevant ability is neither necessary nor sufficient for knowledge-how captured by Japanese constructions. We shall argue that such data will open up a gap between otherwise indistinguishable two conceptions of the very topic of knowledge-how, or the debate between intellectualism and anti-intellectualism, namely a debate about the nature of knowledge-how and a debate about the state captured by “know how”, which we call the knowledge-how interpretation and the state interpretation, respectively. Consequently, the results have not only various possible philosophical implications that have not been considered or discussed in the literature but also provide new topics in the theory of knowledge-how, including the question of which interpretation of the topic is correct itself.
Addictive Design as an Unfair Commercial Practice: The Case of Hyper-Engaging Dark Patterns
Authors: Esposito Fabrizio , Maciel Cathoud Ferreira Thaís 
Published: March 2024

AbstractThis article explains why hyper-engaging dark patterns should be considered unlawful in the European Union even though they are very common online, particularly on content-sharing platforms. A hyper-engaging dark pattern is a digital interface with an addictive design: it makes users spend more time interacting with the service by making use of big data analytics and one or more behavioural trait. Hyper-engaging dark patterns are a form of hypernudge. They exploit the dopamine cycle, reduce users’ autonomy and may have additional detrimental health effects. The Unfair Commercial Practices Directive should be interpreted as prohibiting them either as a form of undue influence or under the general test pursuant to Article 5. Both the Digital Services Act and the Artificial Intelligence Act can play a beneficial but merely complementary role in combatting the diffusion of hyper-engaging dark patterns.
Scale recurrence lemma and dimension formula for Cantor sets in the complex plane
Authors: T. DE A. MOREIRA CARLOS GUSTAVO , ZAMUDIO ESPINOSA ALEX MAURICIO 
Published: March 2024

AbstractWe prove a multidimensional conformal version of the scale recurrence lemma of Moreira and Yoccoz [Stable intersections of regular Cantor sets with large Hausdorff dimensions. Ann. of Math. (2)154(1) (2001), 45–96] for Cantor sets in the complex plane. We then use this new recurrence lemma, together with Moreira’s ideas in [Geometric properties of images of Cartesian products of regular Cantor sets by differentiable real maps. Math. Z.303 (2023), 3], to prove that under the right hypothesis for the Cantor sets
$K_1,\ldots ,K_n$
and the function
$h:\mathbb {C}^{n}\to \mathbb {R}^{l}$
, the following formula holds:
$$ \begin{align*}HD(h(K_1\times K_2 \times \cdots\times K_n))=\min \{l,HD(K_1)+\cdots+HD(K_n)\}.\end{align*} $$
Impact of lipid emulsions in parenteral nutrition on platelets: a literature review
Authors: Kisioglu Betul , Tamer Funda 
Published: March 2024

Abstract
Lipid emulsions are essential components of parenteral nutrition solutions that provide energy and essential fatty acids. The complexity of the formulations of lipid emulsions may lead to adverse outcomes such as platelet reactivity and changes in platelet aggregation and related coagulation. Platelets are responsible for haemostasis; they activate and demonstrate morphological changes upon extracellular factors to maintain blood fluidity and vascular integrity. Although parenteral nutrition lipid emulsions are generally found safe with regard to modulation of platelet activity, studies are still accumulating. Thus, this review aims to investigate platelet-related changes by parenteral nutrition lipid emulsions in human studies. Studies have pointed out patients at risk of bleeding and increased platelet aggregation responses due to the administration of lipid emulsions. Lipid emulsions may further benefit patients at high risk of thrombosis due to anti-thrombotic effects and should be cautiously used in patients with thrombocytopenia. The reported platelet-related changes might be associated with the fatty acid change in the plasma membranes of platelets following changes in platelet synthesis and plasma levels of eicosanoids. In conclusion, studies investigating platelets and parenteral nutrition should be supported to minimize the adverse effects and to benefit from the potential protective effects of parenteral nutrition lipid emulsions.
From intention to action – cultivating future-ready One Health agents of change
Authors: Stephen Craig , Wilcox Alana , Provencher Jennifer 
Published: March 2024

Abstract
We used a narrative literature review to identify attributes of One Health practitioners who can close the gap between intention and action to protect and promote health in this era of polycrises. The intention in this essay was to instigate discourse that challenges the current state of One Health teaching and practice, thus helping us reflect on how to future-ready One Health. One Health researchers and practitioners must become agents of change who accelerate and amplify innovations that promote One Health as a settings-based approach to advance interspecies and intergenerational health equity. This essay outlines how future readiness and disruption are intertwined and proposes that One Health training needs to cultivate curiosity, agility and convergence thinking to create future-ready researchers and practitioners. Institutional systems that can support future-ready One Health agents of change will need to be attentive to mechanisms that close the knowing-to-doing gap and promote crossing barriers. Game changing One Health requires greater investment in cross-cutting capacities and ideas that will make it easier to see what is working and for whom. At the heart of this issue is the need to mainstream concepts of fairness and redistribution of the health resources between people, animals, and settings.

AbstractBackgroundAlthough dopaminergic disturbances are well-known in schizophrenia, the understanding of dopamine-related brain dynamics remains limited. This study investigates the dynamic coactivation patterns (CAPs) associated with the substantia nigra (SN), a key dopaminergic nucleus, in first-episode treatment-naïve patients with schizophrenia (FES).MethodsResting-state fMRI data were collected from 84 FES and 94 healthy controls (HCs). Frame-wise clustering was implemented to generate CAPs related to SN activation or deactivation. Connectome features of each CAP were derived using an edge-centric method. The occurrence for each CAP and the balance ratio for antagonistic CAPs were calculated and compared between two groups, and correlations between temporal dynamic metrics and symptom burdens were explored.ResultsFunctional reconfigurations in CAPs exhibited significant differences between the activation and deactivation states of SN. During SN activation, FES more frequently recruited a CAP characterized by activated default network, language network, control network, and the caudate, compared to HCs (F = 8.54, FDR-p = 0.030). Moreover, FES displayed a tilted balance towards a CAP featuring SN-coactivation with the control network, caudate, and thalamus, as opposed to its antagonistic CAP (F = 7.48, FDR-p = 0.030). During SN deactivation, FES exhibited increased recruitment of a CAP with activated visual and dorsal attention networks but decreased recruitment of its opposing CAP (F = 6.58, FDR-p = 0.034).ConclusionOur results suggest that neuroregulatory dysfunction in dopaminergic pathways involving SN potentially mediates aberrant time-varying functional reorganizations in schizophrenia. This finding enriches the dopamine hypothesis of schizophrenia from the perspective of brain dynamics.
Enlightened and Counter-Revolutionary: Revisiting the Origins of Galician Ruthenian Nation-Building
Authors: Hen-Konarski Tomasz 
Published: March 2024

AbstractThis article offers an alternative focus for the study of the Ruthenian (Ukrainian) nation-building in early Austrian Galicia. It portrays elite Greek Catholic churchmen who made political claims about a self-standing Ruthenian nation already in the first decade of the nineteenth century. It argues that their political innovations were enabled by the ambitious state-building projects implemented in the second half of the eighteenth century by the Austrian government, most importantly new seminaries that cultivated an ethos of state service among Catholic clergymen. The early Ruthenian nationalism espoused by Greek Catholic prelates neither aspired to mobilize masses nor ascribed much importance to language rights, the kernel of nationalist struggles in later periods. It was rather a polemical device deployed to legitimize their rejection of the Polish national allegiance, associated with dynamically evolving republican traditions. By locating the Galician Ruthenian case in a regional comparative perspective, the article outlines the broader significance of this interpretation, interrogating some received wisdoms about the so-called non-historical nationalisms of Central and Eastern Europe.
Gendering Late Medieval Habsburg Dynastic Politics: Maximilian I and His Social Networks
Authors: Lutter Christina 
Published: March 2024

AbstractWhile gender history has developed into a powerful branch of premodern history, we still know little about gender relations around Maximilian I. One reason is that research concentrated for a long time on the individual personality of the emperor without paying much attention to the manifold relations among men and women that in fact contributed to establishing his rule. Another reason is the specific constellations of Maximilian's relationships with his wives Mary of Burgundy and Bianca Maria Sforza, with his daughter Margaret of Austria and grand-daughter Mary of Hungary, which have been mostly discussed in the framework of their personal courts and regional politics and less in a wider comparative perspective. Against the backdrop of recent approaches to dynastic politics, role models, and agency, I will, first, discuss the gendered dimensions of Maximilian's dynastic politics in their wider geo-political and socio-cultural context. I will, second, move beyond a focus on key dynastic actors to take into account personal networks as fundamental for any type of premodern rule. Following court ladies and female servants and the social networks they were part of I will outline the interrelations between social ascent, office, and the politics of kinship and gender at court.
Gendered repartnering in later life: structural and processual dimensions of the transition into new relationships
Authors: Bischoff Luisa 
Published: March 2024

Abstract
Against the backdrop of demographic change and the pluralisation of living arrangements, the article focuses on repartnering after widowhood, divorce and separation in older age in Germany. While theoretically framing repartnering as a lifecourse transition, the question arises of how later-life relationships form in relation to gender- and ageing-specific as well as structural and processual dimensions. Since previous research indicates that there are gender-specific patterns when repartnering in older age which differ from repartnering in middle age, the article explicitly accounts for gendered ageing and attitudes towards ageing. Using data from the German Ageing Survey (1996–2017), longitudinal hybrid panel regressions are modelled for 3,653 respondents, 11,628 observations and 179 new relationships. I propose to understand within-effects as processual and between-effects as structural dimensions of repartnering. The results for the structural dimensions show that the likelihood of repartnering is higher for men and for individuals with more negative attitudes towards ageing. The results for the processual dimensions show how repartnering becomes less likely the older one gets and the more positive one's attitudes towards ageing become. The interaction term for gender and ageing shows that ageing has a stronger influence on the likelihood to repartner for women than for men. Additionally, the findings reveal a difference between forms of singlehood: in the short term, repartnering is less likely for divorced or separated individuals than for widowed individuals, whereas the opposite effect shows in the long term. In sensitising the lifecourse perspective with gender- and ageing-specific concepts and analytically separating processual and structural dimensions, this article demonstrates the importance of gendered ageing and of the linkage between relationship transitions. Applying hybrid panel models to lifecourse transitions in older age reveals the processual dynamic and structural embeddedness of repartnering in older age.
Measuring multidimensional heterogeneity in emergent social phenomena

Published: March 2024

Abstract
Measuring inequalities in a multidimensional framework is a challenging problem, which is common to most field of science and engineering. Nevertheless, despite the enormous amount of researches illustrating the fields of application of inequality indices, and of the Gini index in particular, very few consider the case of a multidimensional variable. In this paper, we consider in some details a new inequality index, based on the Fourier transform, that can be fruitfully applied to measure the degree of inhomogeneity of multivariate probability distributions. This index exhibits a number of interesting properties that make it very promising in quantifying the degree of inequality in datasets of complex and multifaceted social phenomena.
