Published: November 2023

AbstractLaughter is one of the most common non-verbal features; however, contrary to the previous assumptions, it may also act as signals of bonding, affection, emotional regulation agreement or empathy (Scott et al. Trends Cogn Sci 18:618–620, 2014). Although previous research agrees that laughter does not form a uniform group in many respects, different types of laughter have been defined differently by individual research. Due to the various definitions of laughter, as well as their different methodologies, the results of the previous examinations were often contradictory. The analysed laughs were often recorded in controlled, artificial situations; however, less is known about laughs from social conversations. Thus, the aim of the present study is to examine the acoustic realisation, as well as the automatic classification of laughter that appear in human interactions according to whether listeners consider them to be voluntary or involuntary. The study consists of three parts using a multi-method approach. Firstly, in the perception task, participants had to decide whether the given laughter seemed to be rather involuntary or voluntary. In the second part of the experiment, those sound samples of laughter were analysed that were considered to be voluntary or involuntary by at least 66.6% of listeners. In the third part, all the sound samples were grouped into the two categories by an automatic classifier. The results showed that listeners were able to distinguish laughter extracted from spontaneous conversation into two different types, as well as the distinction was possible on the basis of the automatic classification. In addition, there were significant differences in acoustic parameters between the two groups of laughter. The results of the research showed that, although the distinction between voluntary and involuntary laughter categories appears based on the analysis of everyday, spontaneous conversations in terms of the perception and acoustic features, there is often an overlap in the acoustic features of voluntary and involuntary laughter. The results will enrich our previous knowledge of laughter and help to describe and explore the diversity of non-verbal vocalisations.
The continuous stochastic gradient method: part I–convergence theory

Published: November 2023

AbstractIn this contribution, we present a full overview of thecontinuous stochastic gradient(CSG) method, including convergence results, step size rules and algorithmic insights. We consider optimization problems in which the objective function requires some form of integration, e.g., expected values. Since approximating the integration by a fixed quadrature rule can introduce artificial local solutions into the problem while simultaneously raising the computational effort, stochastic optimization schemes have become increasingly popular in such contexts. However, known stochastic gradient type methods are typically limited to expected risk functions and inherently require many iterations. The latter is particularly problematic, if the evaluation of the cost function involves solving multiple state equations, given, e.g., in form of partial differential equations. To overcome these drawbacks, a recent article introduced the CSG method, which reuses old gradient sample information via the calculation of design dependent integration weights to obtain a better approximation to the full gradient. While in the original CSG paper convergence of a subsequence was established for a diminishing step size, here, we provide a complete convergence analysis of CSG for constant step sizes and an Armijo-type line search. Moreover, new methods to obtain the integration weights are presented, extending the application range of CSG to problems involving higher dimensional integrals and distributed data.
Saturation-Based Boolean Conjunctive Query Answering and Rewriting for the Guarded Quantification Fragments
Authors: Zheng Sen , Schmidt Renate A. 
Published: November 2023

AbstractQuery answering is an important problem in AI, database and knowledge representation. In this paper, we develop saturation-based Boolean conjunctive query answering and rewriting procedures for the guarded, the loosely guarded and the clique-guarded fragments. Our query answering procedure improves existing resolution-based decision procedures for the guarded and the loosely guarded fragments and this procedure solves Boolean conjunctive query answering problems for the guarded, the loosely guarded and the clique-guarded fragments. Based on this query answering procedure, we also introduce a novel saturation-based query rewriting procedure for these guarded fragments. Unlike mainstream query answering and rewriting methods, our procedures derive a compact and reusable saturation, namely a closure of formulas, to handle the challenge of querying for distributed datasets. This paper lays the theoretical foundations for the first automated deduction decision procedures for Boolean conjunctive query answering and the first saturation-based Boolean conjunctive query rewriting in the guarded, the loosely guarded and the clique-guarded fragments.
Residential satisfaction in student housing: an empirical study in Stockholm, Sweden
Authors: Gong Anqi , Söderberg Bo 
Published: November 2023

AbstractDespite the widely-recognized importance of student housing in educational settings, the housing experience of university students remains understudied. This study attempts to assess the residential satisfaction in student housing in Stockholm, Sweden and the indicators which predict residential satisfaction in this context. Moreover, it explores whether residential satisfaction varies between different socio-demographic groups. A list of satisfaction indictors was identified through reviewing literature and a number of semi-structured interviews, thereafter data was collected from a questionnaire survey with simple random sampling. The responses were analysed through descriptive analysis, stepwise regression, t-test and analysis of variance. The results show that the current occupants are generally satisfied with the student housing in Stockholm. Seven indicators appear to be predictors of satisfaction, among which the strongest ones are kitchen facilities, cleanliness and accessibility to public transport stations. In terms of socio-demographic characteristics, those with a shorter residential duration are found to be more satisfied. Furthermore, studio residents are more satisfied than corridor-room residents.

AbstractPlasma decomposition reactions are used for various gas phase chemical processes including the decomposition of ammonia. In this work we show that pure ammonia can be effectively decomposed at atmospheric pressure and ambient temperature using a packed-bed plasma reactor moderated with BaTiO3 ferroelectric pellets without catalyst. The decomposition rate and energy efficiency of this ferroelectric barrier discharge reactor have been monitored as a function of applied voltage (up to a maximum value of 2.5 kV) and flow rate. For each operating condition reaction efficiencies have been correlated with the parameters defining the electrical response of the reactor. It is found that plasma current and volume inside the reactor and hence the energy efficiency of the process and the decomposition rate vary with the applied voltage and the flow of ammonia (a maximum decomposition rate of 14% and an energy efficiency of 150 LH2/kWh has been determined under optimized operation conditions). The role of back reactions (i.e. N2 + 3H2 → 2NH3) in decreasing reactor performance is another key effect affecting the overall efficiency for the ammonia decomposition. The possibilities of ferroelectric barrier discharge reactors to induce the decomposition of ammonia and the importance of keeping the operating temperature below the Curie temperature of the ferroelectric material are highlighted.
Phasing-out ‘coal tradition’ in favour of ‘renewable colonialism’: how the press contributes to the discursive (de)legitimization of coal and renewables in a coal region in transition
Authors: Biddau Fulvio , Rizzoli Valentina , Sarrica Mauro 
Published: November 2023

AbstractThis article examines the Sulcis coal region in Italy and illustrates how discursive dynamics can impede energy transition by delegitimizing coal decline and the diffusion of renewable energies. Combining quantitative analyses of textual data and argumentative discourse analysis, we analyze newspaper articles published between 2011 and 2021 in the national, regional, and local press. Our findings reveal that shifts in topic salience and storylines reflect different transition phases (coal legitimacy, regime destabilization, and reconfiguration). Throughout the analyzed period, newspapers have cultivated a discursive environment that weakens efforts to phase out coal and promote low-carbon energy by amplifying particular storylines endorsed by competing discourse coalitions. Media discourse consistently portrays decarbonization and coal phase-out as threatening, anticipating disruption to regional livelihoods and traditions. Over time, renewable energies are marginalized or hindered by storylines promoting regime stability (coal legitimacy), soft transformation (coal-to-gas transition), and, finally, a reconfiguration (utility-scale renewable transition) promoted by incumbents and resisted by locally based discourse coalitions perceiving it as a form of colonialism. This study sheds light on the interplay between discourse dynamics and the complexities and challenges of the destabilization–reconfiguration pathway of coal regions. It contends that approaches combining both build-up and break-down dynamics into the analysis of transitions can offer a more nuanced, politically sensitive understanding and practical insights to instigate and navigate more equitable destabilization–reconfiguration pathways.

AbstractAlzheimer’s disease (AD) is a globally prevalent form of dementia that impacts diverse populations and is characterized by progressive neurodegeneration and impairments in executive memory. Although the exact mechanisms underlying AD pathogenesis remain unclear, it is commonly accepted that the aggregation of misfolded proteins, such as amyloid plaques and neurofibrillary tau tangles, plays a critical role. Additionally, AD is a multifactorial condition influenced by various genetic factors and can manifest as either early-onset AD (EOAD) or late-onset AD (LOAD), each associated with specific gene variants. One gene of particular interest in both EOAD and LOAD is RIN3, a guanine nucleotide exchange factor. This gene plays a multifaceted role in AD pathogenesis. Firstly, upregulation of RIN3 can result in endosomal enlargement and dysfunction, thereby facilitating the accumulation of beta-amyloid (Aβ) peptides in the brain. Secondly, RIN3 has been shown to impact the PICLAM pathway, affecting transcytosis across the blood-brain barrier. Lastly, RIN3 has implications for immune-mediated responses, notably through its influence on the PTK2B gene. This review aims to provide a concise overview of AD and delve into the role of the RIN3 gene in its pathogenesis.
Navigating uncertainty: exploring electricity demand dynamics in Swedish industrial sectors amid global shocks and instability
Authors: Wadström Christoffer , Johansson Maria , Uddin Gazi Salah 
Published: November 2023

AbstractThis study aims to provide insights into the factors shaping electricity demand in Swedish industrial sectors using the nonlinear version of the autoregressive distributed lag model (NARDL). This approach captures the complex short- and long-run relationships between uncertainty and electric power use in Swedish industrial sectors. The results reveal sector-specific responses to uncertainties and asymmetries in electricity use patterns. By examining the entire industrial sector in Sweden, this approach uncovers underlying issues and hidden patterns, while also providing insights into the functioning and behaviour of industrial systems. The rapid electrification and new green industrialisation initiatives in Sweden, coupled with the integration of a circular economy, underscore the importance of understanding the dynamics of electricity use in the face of uncertain shocks. This knowledge is vital for ensuring, amongst other things, grid stability, mitigating the need for costly peaking capacity, and identifying potential challenges in the interconnection of energy and material circular flows.
Emotionen als Gegenstand von Erziehung
Authors: Budde Jürgen , Hellberg Lotta 
Published: November 2023

ZusammenfassungEthnographische Beobachtungen zeigen, dass Erziehung oftmals durch Emotionalisierungen seitens der Pädagog_innen geschieht. Anhand theoretischer wie empirischer Reflexionen fragt der Beitrag danach, in welcher Weise Regeln und Normen in pädagogischen Institutionen der Kindheit insbesondere mit Blick auf die Bedeutung von Emotionen prozessiert werden. Argumentiert wird, dass dadurch einer individualisierenden Perspektive Vorschub geleistet wird, die durch den Bezug auf Bindung, Verletzung und Beschämung gekennzeichnet ist und so deprofessionalisierend wirken können. Regeln, so die Beobachtung, werden nicht ausgehandelt, sondern anhand emotionaler Betroffenheiten aufgeführt.
Frailty Among Older Indians: State-Level Factors

Published: November 2023

AbstractFrailty is a common syndrome affecting older adults. While frailty has well-established relationships with multiple adverse health outcomes and death, the role of the social and economic environment in the development of frailty is less clear. We consider this relationship in India, which has a growing population of older adults whose environments have undergone extensive social and economic changes over the last few decades. We compare the distributions of frailty among older adults across the states of India and explore the influence of both current social and economic indicators and historical indicators at the state level. We find substantial variation in the state-level prevalence of frailty, which remains even after sex stratification and age standardization. We also find significant associations between frailty and current (2018) and historic (1981) state-level socioeconomic variables. We conclude with a discussion of the scientific and policy implications of early-life and contemporaneous social and economic conditions for the frailty of older adults.

Published: November 2023

AbstractPrimary headache is a common somatic disorder in childhood that significantly affects quality of life. The condition is strongly associated with a variety of internalizing and externalizing disorders, and several dimensions are recognized to play a role in its development and expression, including attachment bonds. The present study aimed at exploring the associations between somatic symptoms, internalizing and externalizing problems, and attachment dimensions in a group of children and adolescents suffering from headache. The predictive effect of internalizing/externalizing problems and attachment dimensions on somatic symptoms was also explored. A sample of 50 children/adolescents with a headache diagnosis (i.e., 36 girls, 14 boys; mean age 13.18 years; SD = 2.85) participated in the study and completed the Children’s Somatization Inventory-24, the Experiences in Close Relationships Scale–Revised Child version, and a brief sociodemographic questionnaire. Mothers completed the Child Behavior Checklist 6–18. The correlational analysis revealed positive associations between child somatic symptoms and age, internalizing problems, and attachment anxiety and avoidance to the mother and the father, respectively; and a negative association between child somatic symptoms and secure attachment to the father. The regression analysis highlighted the significant effect of ECR-RC Avoidance-Father and CBCL Internalizing Problems in predicting greater somatic symptoms in young headache patients. The present findings highlight avoidant attachment to fathers and internalizing problems as risk factors for greater somatic symptoms in children/adolescents with headache. The results suggest that greater somatic symptoms in this clinical population may represent a learned maladaptive behavior to satisfy attachment needs. Clinical implications are discussed.

Published: November 2023

AbstractInstitutionalized supporter participation is a traditional part of German professional football clubs. Due to commercialization, some challenging issues have arisen in recent years regarding supporter participation. To develop new approaches for improving participation, the study uses a social sustainability perspective, illustrating that social sustainability elements help to develop and structure the potential for improvement of participation in German professional football. By identifying and discussing links between social sustainability and institutionalized supporter participation, we contribute to the conceptualization of sustainable participation. Our research supports the creation of an inclusive and sustainable fan community where fans can actively participate in decisions and actions that affect their current and future fandom environment. Based on the social sustainability principles of health, influence, competence, impartiality, and meaning-making, we compile the following characteristics of sustainable participation: social well-being oriented participation, direct influence, regular voting rights, representative participation, appealable resolutions, information-based participation, barrier-free participation, democratic voting, established constitutions, and encouraged participation. This conceptualization provides approaches and foundations for future investigations regarding participation research in football and practical implications for member associations, association members, league organizers, and other stakeholders to establish and improve institutionalized participation.

Abstract
Background
The overexpression of ALOX5AP has been observed in many types of cancer and has been identified as an oncogene. However, its role in acute myeloid leukemia (AML) has not been extensively studied. This study aimed to identify the expression and methylation patterns of ALOX5AP in bone marrow (BM) samples of AML patients, and further explore its clinical significance.

Methods
Eighty-two de novo AML patients and 20 healthy donors were included in the study. Meanwhile, seven public datasets from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) were included to confirm the alteration of ALOX5AP. Receiver operating characteristic (ROC) curve analysis was applied to determine the discriminative capacity of ALOX5AP expression to discriminate AML. The prognostic value of ALOX5AP was identified by the Kaplan–Meier method and log-rank test. It was further validated in four independent cohorts (n = 1186). Significantly different genes associated with ALOX5AP expression were subsequently compared by LinkedOmics, and Metascape database.

Results
The level of ALOX5AP expression was significantly increased in bone marrow cells of AML patients compared with healthy donors (P < 0.05). ROC curve analysis suggested that ALOX5AP expression might be a potential biomarker to discriminate AML from controls. ALOX5AP overexpression was associated with decreased overall survival (OS) in AML according to the TCGA data (P = 0.006), which was validated by other four independent cohorts. DNA methylation levels of ALOX5AP were significantly lower in AML patients compared to normal samples (P < 0.05), as confirmed in the Diseasemeth database and the independent cohort GSE63409. ALOX5AP level was positively associated with genes with proleukemic effects such as PAX2, HOX family, SOX11, H19, and microRNAs that act as oncogenes in leukemia, such as miR125b, miR-93, miR-494, miR-193b, while anti-leukemia-related genes and tumor suppressor microRNAs such as miR-582, miR-9 family and miR-205 were negatively correlated.

Conclusion
ALOX5AP overexpression, associated with its hypomethylation, predicts poorer prognosis in AML.
Plasma powder transferred arc additive manufacturing of ((Fe, Ni)-Al) intermetallic alloy and resulting properties
Authors: Treutler Kai 
Published: November 2023

AbstractIntermetallic alloys such as iron aluminides are of increasing interest for high-temperature applications due to their properties. However, their application potential is restricted by their limited machinability with conventional manufacturing methods such as milling. Arc-based additive manufacturing offers an approach to produce these materials to final contour or with very little post-processing. However, the properties of many intermetallic alloys, such as low toughness, require a special manufacturing process. Using a selected iron-nickel-aluminum intermetallic compound as an example, a possible process, including a subsidiary heat treatment, for the arc-based additive manufacturing of materials based on brittle intermetallic materials is presented. This process route could enable the production of structural components. In addition, some basic mechanical properties that can be achieved in a component are shown proportionally. These properties include initial investigations into the wear resistance of this kind of compounds. It is shown that these intermetallic compounds have a superior wear resistance compared to commonly used co-base alloys but have a lower density compared to cobalt-basis alloys.
