A simple extension of Timoshenko beam model to describe dissipation in cementitious elements
Authors: Aretusi Giuliano , Cardillo Christian , Salvatori Antonello , Bednarczyk Ewa , Fedele Roberto 
Published: August 2024

AbstractIn this paper, an extension of the Timoshenko model for plane beams is outlined, with the aim of describing, under the assumption of small displacements and strains, a class of dissipative mechanisms observed in cementitious materials. In the spirit of micromorphic continua, the modified beam model includes a novel kinematic descriptor, conceived as an average sliding relevant to a density of micro-cracks not varying along time. For the pairs of rough surfaces, in which such a distribution of micro-cracks is articulated, both an elastic deformation and a frictional dissipation are considered, similarly to what occurs for the fingers of the joints having a tooth saw profile. The system of governing differential equations, of the second order, is provided by a variational approach, endowed by standard boundary conditions. To this purpose, a generalized version of the principle of virtual work is used, in the spirit of Hamilton–Rayleigh approach, including as contributions: (i) the variation of the inner elastic energy, generated by the linear elasticity of the sound material and, in a nonlinear way, by the mutual, reversible deformation of the asperities inside the micro-cracks; (ii) the virtual work of the external actions consistent with the beam model, i.e., the distributed transversal forces and the moments per unit lengths; besides these two contributions, constituting the conservative part of the system, (iii) the dissipation due to friction specified through a smooth Rayleigh potential, entering a nonlinear dependence of viscous and Coulomb type on the sliding rate. Through a COMSOL Multiphysics"Equation missing" implementation, 1D finite element analyses are carried out to simulate structural elements subjected to three- and four-point bending tests with alternating loading cycles. The dissipation of energy is investigated at varying the model parameters, and the predictions turn out to be in agreement with preliminary data from an experimental campaign. The present approach is expected to provide a valuable tool for the quantitative and comparative assessment of the hysteresis cycles, favoring the robust design of cementitious materials.

Navigating the maze of mass spectra: a machine-learning guide to identifying diagnostic ions in O-glycan analysis
Authors: Urban James , Joeres Roman , Thomès Luc , Thomsson Kristina A. , Bojar Daniel 
Published: August 2024

Abstract
Structural details of oligosaccharides, or glycans, often carry biological relevance, which is why they are typically elucidated using tandem mass spectrometry. Common approaches to distinguish isomers rely on diagnostic glycan fragments for annotating topologies or linkages. Diagnostic fragments are often only known informally among practitioners or stem from individual studies, with unclear validity or generalizability, causing annotation heterogeneity and hampering new analysts. Drawing on a curated set of 237,000 O-glycomics spectra, we here present a rule-based machine learning workflow to uncover quantifiably valid and generalizable diagnostic fragments. This results in fragmentation rules to robustly distinguish common O-glycan isomers for reduced glycans in negative ion mode. We envision this resource to improve glycan annotation accuracy and concomitantly make annotations more transparent and homogeneous across analysts.

Published: August 2024

AbstractIn this article we generalize the Bohr–Sommerfeld rule for scalar symbols at a potential well to matrix-valued symbols having eigenvalues that may coalesce precisely at the bottom of the well. As an application, we study the existence of approximately flat bands in moiré heterostructures such as strained two-dimensional honeycomb lattices in a model recently introduced by Timmel and Mele.
Certolizumab-induced sarcoidosis in a patient with psoriatic arthritis – a case report and review of literature
Authors: Biernikowicz Małgorzata , Pilch Weronika , Wojturska Wiktoria , Korkosz Mariusz , Nowakowski Jarosław 
Published: August 2024

AbstractTumour necrosis factor-α (TNF- α) antagonists are considered a significant therapeutic option in the treatment of sarcoidosis. Nevertheless, their use can also paradoxically result in sarcoidosis-like reactions. Here, we present a case of a 56-year-old patient with psoriatic arthritis who after 3 months of certolizumab therapy developed pulmonary sarcoidosis. Therefore, certolizumab was discontinued and prednisone initiated. Subsequently, 4 months later a complete remission of interstitial lesions was observed. Due to insufficient control of psoriatic arthritis, upadacitinib and methotrexate were prescribed and despite initial improvement, a couple of months later a massive exacerbation of skin psoriasis occurred and the treatment was switched to secukinumab. As of today, no evidence of sarcoidosis recurrence has been noted. Drug-induced sarcoidosis-like reactions (DISR) appear to be less frequently associated with certolizumab rather than with other anti-TNF-α agents. However, specific mechanisms of this phenomenon remain unclear and require future investigation.
Towards inclusive collaboration in volcanology: guidelines for best-engagement protocols in international collaboration
Authors: IAVCEI-INVOLC International Network  
Published: August 2024

AbstractThe International Network for Volcanology Collaboration (INVOLC) is a network formalised by the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI) with the specific ambition to enhance volcanology globally through improved international collaboration. IAVCEI-INVOLC was created with a focus on volcano scientists working in resource-constrained contexts, including those based in low- or middle-income countries. After a community-wide online survey and inaugural workshop during which INVOLC’s ambitions were discussed, a series of challenges, as commonly experienced by those working in resource-constrained settings, were identified. These challenges may present barriers to participation in volcano science in an international context and are related to both organisational resources (financial, human, technical) and inclusion in research collaborations. In this perspectives paper, we present a series of 15 guidelines for best-engagement protocols in international collaboration in volcanology that may be adopted during times of quiescence, volcanic unrest and/or an eruption and its aftermath. Our aspiration is that these guidelines will help build more respectful, equitable and sustainable partnerships that will ultimately advance the science of volcanology.
Emotional text messages affect the early processing of emoticons depending on their emotional congruence: evidence from the N170 and EPN event related potentials

Published: August 2024

AbstractEmoticons have been considered pragmatic cues that enhance emotional expressivity during computer-mediated communication. Yet, it is unclear how emoticons are processed in ambiguous text-based communication due to incongruences between the emoticon's emotional valence and its context. In this study, we investigated the electrophysiological correlates of contextual influence on the early emotional processing of emoticons, during an emotional congruence judgment task. Participants were instructed to judge the congruence between a text message expressing an emotional situation (positive or negative), and a subsequent emoticon expressing positive or negative emotions. We analyzed early event-related potentials elicited by emoticons related to face processing (N170) and emotional salience in visual perception processing (Early Posterior Negativity, EPN). Our results show that accuracy and Reaction Times depend on the interaction between the emotional valence of the context and the emoticon. Negative emoticons elicited a larger N170, suggesting that the emotional information of the emoticon is integrated at the early stages of the perceptual process. During emoticon processing, a valence effect was observed with enhanced EPN amplitudes in occipital areas for emoticons representing negative valences. Moreover, we observed a congruence effect in parieto-temporal sites within the same time-window, with larger amplitudes for the congruent condition. We conclude that, similar to face processing, emoticons are processed differently according to their emotional content and the context in which they are embedded. A congruent context might enhance the emotional salience of the emoticon (and therefore, its emotional expression) during the early stages of their processing.

Abstract
Background
The number of metastatic lymph nodes (LNs) is an important prognostic factor for esophageal cancer, and N staging is important for prognostic stratification. The optimal cutoff values for clinical (cN) and pathologic N (pN) staging should be reconsidered following advances in neoadjuvant therapy.

Methods
The study included 655 patients who underwent esophagectomy between January 2014 and December 2016 in four high-volume centers in Japan. Optimal cutoff values for the number of metastatic LNs in cN and pN staging were examined using X-tile, and their prognostic performance was validated using the Kaplan–Meier method.

Results
The cutoff values were 1, 2, and 3 for cN staging and 1, 3, and 7 for pN staging. Prognosis was significantly better in patients with cN0 than in those with modified (m)-cN1 (p = 0.0211). However, prognosis was not significantly different among the patients with m-cN1, m-cN2, and m-cN3 disease. Prognosis was significantly different among the patients with pN0, pN1, pN2, and pN3 disease (pN0 vs pN1, p < 0.0001; pN1 vs pN2, p < 0.0001; pN2 vs pN3, p < 0.0001). In patients who received preoperative neoadjuvant therapy, prognosis, which was not significantly different among the patients with cN0, m-cN1, m-cN2, and m-cN3 disease (cN0 vs m-cN1, p = 0.5675; m-cN1 vs m-cN2, p = 0.4425; m-cN2 vs m-cN3, p = 0.7111), was significantly different among the patients with pN0, pN1, pN2, and pN3 disease (pN0 vs pN1, p = 0.0025; pN1 vs pN2, p = 0.0046; pN2 vs pN3, p = 0.0104).

Conclusions
cN has no prognostic impact in patients who underwent preoperative treatment followed by esophagectomy, despite the optimization of cN classification. The conventional TNM8th pN classification is useful for predicting prognosis even for patients who have undergone preoperative treatment. The conventional cutoffs for metastatic LNs in the International Union against Cancer tumor node metastasis staging system are valid and can be effectively used in clinical practice.
The horror of corporate harms: purdue pharma and the opioid epidemic
Authors: Crofts Penny , van Rijswijk Honni 
Published: August 2024

AbstractThere has been a great deal written about Purdue and the opioid epidemic in multiple disciplines, including dismay about the failure of the criminal legal system to adequately conceptualize and respond to Purdue’s responsibility for causing the epidemic. Rather than lingering on the failure of the criminal legal system, we read Purdue’s responsibility as and through horror. The harms caused by Purdue do not fit into criminal legal categories as they are currently written and, instead, are more analogous to harms portrayed in the horror genre. Moreover, Purdue could achieve these harms only through the failure and betrayal of people and institutions of authority, a classic trope of the horror genre. We develop a concept of routine horror to explore the ways in which corporate harms are inflicted through everyday practices and products, enabled by routine systems of regulations and laws. On this account, the routines enable the harms and are harmful in and of themselves, leaving us with no one to trust and no place to turn. In the absence of effective law, we remain stuck in a horror story.
Punjabi “housewives” in central Italy: navigating patriarchy, labor exploitation, and welfare exclusion
Authors: Laudini Annamaria 
Published: August 2024

AbstractWho benefits from the exploitation of women’s work, and how? Marxist feminists in the 1970s–1980s and recently theorists of Social Reproduction argued that women’s work is exploited twice, or “super-exploited,” by capital and patriarchy. Such “super-exploitation” is sustained by the process of “housewifization,” which legitimizes the extraction and accumulation of surplus value from the social reproductive work of women. The housewife ideology not only mystifies social reproductive work as natural — thereby legitimizing it as free — but also frames women’s productive work as marginal — thereby legitimizing it as cheaper and more precarious. Building on Maria Mies’ (1981) famous study of women lacemakers in India, where the devaluation of women’s work is shown to serve both capital and patriarchy, I analyze the experiences of Punjabi “housewives” in central Italy, exploring them through the lens of one family and specifically its youngest and eldest daughters, whom I interviewed during ethnographic fieldwork. I show how, despite the essential role played by these women in their family mobility project, the housewife ideology — together with other patriarchal constructs of honor and caste endogamy — obscures the value of their social reproductive and productive work and imposes a number of restrictions on their freedom. I find, further, that their super-exploitation is aggravated in the context of migration: the labor exploitation and welfare exclusion that they face in Italy due to the country’s exclusionary immigration regime and unregulated capitalist market complicate their chances to challenge the oppressive relations they are involved in.
Tip-of-the-Tongue Experiences as Cognitive Phenomenology
Authors: Medeiros Darren 
Published: August 2024

AbstractWhether metacognitive experiences should be considered evidence for or against cognitive phenomenology is controversial. In this paper I analyze one metacognitive experience, having a word at the tip of one’s tongue, and argue that this experience is an instance of cognitive phenomenology. I develop what I call a Cognitive view of tip-of-the-tongue (TOT) experience, supported by examining the prominent psychological explanation of tip-of-the-tongue states emerging from the science of language production, showing how psychological data suggests that the phenomenal character of tip-of-the-tongue experiences is constituted in part by conceptual representations, from which it follows that tip-of-the-tongue experiences are instances of cognitive phenomenology. This view contrasts with metacognitive embodied affect views of tip-of-the-tongue experiences, and I provide several clarifications and challenges that defenders of these views would have to address to situate their views within the cognitive phenomenology debate. Ultimately, I conclude that the Cognitive view of TOT is better supported by empirical data, and comports better with introspection, in comparison to embodied affect views.
Baby Logic – a Hinge Epistemology
Authors: Ohlhorst Jakob 
Published: August 2024

AbstractEpistemologists have begun paying attention to the phenomenon of core cognition from developmental psychology. Core cognition posits innate automatic cognitive modules that enable children to quickly grasp and learn certain concepts. A key element of core cognition is sometimes named core knowledge because it encodes the constraints, parameters, and concepts that are required for core cognition modules to function. Until now, no successful epistemological account of it has been presented, and it is difficult to integrate into standard accounts of epistemology given that it is only implicitly believed, not accessible to explicit cognitive processing, and innate. In this paper I propose an account of the epistemology of core cognition, focussing on the epistemic status of this core knowledge. I argue that, rather than being knowledge, or some ordinary justified belief, it consists of Wittgensteinian hinge certainties. These are the implicit presupposition that we need for our epistemology to function. I illustrate the argument with the core cognition of causality. Finally, I propose that even though core knowledge consists of unjustified hinges, we are epistemically entitled to trust them to be accurate.

Published: August 2024

AbstractTo make sense of the changes provoked by the Covid-19 pandemic and its immediate aftermath, this paper critically examines digital education policy responses in the context of the ‘new realities’ faced by schooling. Based on seven case studies contributed by authors from Australia, India, Ireland, Italy, Japan, Canada, Sri Lanka, two key questions are addressed: (1) What are the ‘new realities’ of schooling post Covid-19? and (2) How have digital educational policies changed in response to the new realities of schooling? Findings highlight the complexity of the problem of aligning digital education policies at the macro level to the realities experienced at the meso and micro levels of schooling systems. The paper concludes with discussion of the need for, and challenges of, agile policy making at all levels (macro, meso and micro) that are necessary for schooling systems to meet the challenges and realities of a complex changing world.
The Health Status of Undocumented Immigrants from Asian Countries in the United States: A Scoping Review and Recommendations for Future Directions
Authors: Nayak Sameera S. , Cardone Amanda , Soberano Kina , Dhond Meghan 
Published: August 2024

AbstractImmigrants from Asian countries are the fastest-growing undocumented population in the United States (U.S.), yet not much is known about their health. This scoping review identifies the nature and extent of scientific literature on the health of undocumented Asian immigrants in the U.S. We conducted a comprehensive search of six electronic databases in 2024. Inclusion criteria were empirical articles written in English, published in peer-reviewed scientific journals from 2010 to 2024, and focused on a health outcome or health-related issue involving undocumented Asian immigrants. Results are summarized narratively. We identified 13 peer-reviewed publications. Nine studies were quantitative, and four were qualitative. Eight studies were conducted in California; two studies used national secondary data sources. Studies were mixed in their research focus. They covered a range of health outcomes and issues, such as mental health (n = 4), health services and access (n = 2), contraceptive use (n = 1), COVID-19 (n = 2), and HIV (n = 1). Three studies measured self-rated health alongside other conditions, such as disability, health insurance coverage, chronic health conditions, and obesity. Scholarship on the health of undocumented Asian immigrants is a growing research area. Given the small number of studies identified, future research with larger diverse samples, more robust methodology, and greater topical variety are warranted to understand the health of this population better and reduce potential inequities.
Perspectives of Generative AI in Chemistry Education Within the TPACK Framework
Authors: Feldman-Maggor Yael , Blonder Ron , Alexandron Giora 
Published: August 2024

Abstract
Artificial intelligence (AI) has made remarkable strides in recent years, finding applications in various fields, including chemistry research and industry. Its integration into chemistry education has gained attention more recently, particularly with the advent of generative AI (GAI) tools. However, there is a need to understand how teachers’ knowledge can impact their ability to integrate these tools into their practice. This position paper emphasizes two central points. First, teachers technological pedagogical content knowledge (TPACK) is essential for more accurate and responsible use of GAI. Second, prompt engineering—the practice of delivering instructions to GAI tools—requires knowledge that falls partially under the technological dimension of TPACK but also includes AI-related competencies that do not fit into any aspect of the framework, for example, the awareness of GAI-related issues such as bias, discrimination, and hallucinations. These points are demonstrated using ChatGPT on three examples drawn from chemistry education. This position paper extends the discussion about the types of knowledge teachers need to apply GAI effectively, highlights the need to further develop theoretical frameworks for teachers’ knowledge in the age of GAI, and, to address that, suggests ways to extend existing frameworks such as TPACK with AI-related dimensions.
Wasserstein principal component analysis for circular measures
Authors: Beraha Mario , Pegoraro Matteo 
Published: August 2024

AbstractWe consider the 2-Wasserstein space of probability measures supported on the unit-circle, and propose a framework for Principal Component Analysis (PCA) for data living in such a space. We build on a detailed investigation of the optimal transportation problem for measures on the unit-circle which might be of independent interest. In particular, building on previously obtained results, we derive an expression for optimal transport maps in (almost) closed form and propose an alternative definition of the tangent space at an absolutely continuous probability measure, together with fundamental characterizations of the associated exponential and logarithmic maps. PCA is performed by mapping data on the tangent space at the Wasserstein barycentre, which we approximate via an iterative scheme, and for which we establish a sufficient a posteriori condition to assess its convergence. Our methodology is illustrated on several simulated scenarios and a real data analysis of measurements of optical nerve thickness.
