Published: September 2021

AbstractWith the advent of physiological computing systems, new avenues are emerging for the field of learning analytics related to the potential integration of physiological data. To this end, we developed a physiological computing infrastructure to collect physiological data, surveys, and browsing behavior data to capture students’ learning journey in remote learning. Specifically, our solution is based on the Raspberry Pi minicomputer and Polar H10 chest belt. In this work-in-progress paper, we present preliminary results and experiences we collected from a field study with medical students using our developed infrastructure. Our results do not only provide a new direction for more effectively capturing different types of data in remote learning by addressing the underlying challenges of remote setups, but also serve as a foundation for future work on developing a less obtrusive, (near) real-time measurement method based on the classification of cognitive-affective states such as flow or other learning-relevant constructs with the captured data using supervised machine learning.
Environmental life cycle implications of upscaling lithium-ion battery production

Published: September 2021

AbstractPurposeLife cycle assessment (LCA) literature evaluating environmental burdens from lithium-ion battery (LIB) production facilities lacks an understanding of how environmental burdens have changed over time due to a transition to large-scale production. The purpose of this study is hence to examine the effect of upscaling LIB production using unique life cycle inventory data representative of large-scale production. A sub-goal of the study is to examine how changes in background datasets affect environmental impacts.MethodWe remodel an often-cited study on small-scale battery production by Ellingsen et al. (2014), representative of operations in 2010, and couple it to updated Ecoinvent background data. Additionally, we use new inventory data to model LIB cell production in a large-scale facility representative of the latest technology in LIB production. The cell manufactured in the small-scale facility is an NMC-1:1:1 (nickel-manganese-cobalt) pouch cell, whereas in the large-scale facility, the cell produced in an NMC-8:1:1 cylindrical cell. We model production in varying carbon intensity scenarios using recycled and exclusively primary materials as input options. We assess environmental pollution–related impacts using ReCiPe midpoint indicators and resource use impacts using the surplus ore method (ReCiPe) and the crustal scarcity indicator.Results and discussionRemodelling of the small-scale factory using updated background data showed a 34% increase in greenhouse gas emissions — linked to updated cobalt sulfate production data. Upscaling production reduced emissions by nearly 45% in the reference scenario (South Korean energy mix) due to a reduced energy demand in cell production. However, the emissions reduce by a further 55% if the energy is sourced from a low-carbon intensity source (Swedish energy mix), shifting almost all burden to upstream supply chain. Regional pollution impacts such as acidification and eutrophication show similar trends. Toxic emissions also reduce, but unlike other impacts, they were already occurring during mining and ore processing. Lastly, nickel, cobalt, and lithium use contribute considerably to resource impacts. From a long-term perspective, copper becomes important from a resource scarcity perspective.ConclusionsUpscaling LIB production shifts environmental burdens to upstream material extraction and production, irrespective of the carbon intensity of the energy source. Thus, a key message for the industry and policy makers is that further reductions in the climate impacts from LIB production are possible, only when the upstream LIB supply chain uses renewable energy source. An additional message to LCA practitioners is to examine the effect of changing background systems when evaluating maturing technologies.

AbstractDrought stress is one of the major environmental factors that limited crop’s growth and production. Cassava known as a tropical crop that is widely distributed in Sub-Saharan Africa. It has a strong drought tolerance and can grow well under tough environmental conditions. Therefore, understanding how cassava responds to drought stress and coordinates survival and accumulation has great theoretical significance for improving crop drought resistance breeding. Many studies on cassava drought responses mainly focused on the leaf and whole seedling. Nevertheless, how the vasculature plays an important role in plant response to water deficiency remains to be fully elucidated. Here, comparative transcriptome analysis was performed on isolated mesophyll tissue and leaf vein vascular tissue of cassava variety KU50 after mild drought treatment to determine the molecular mechanism behind drought resistance in cassava vasculature. Our results showed that KU50 leaves had increased leaf temperature, with characters of rapidly decreased net photosynthetic rate, stomatal conductance, and transpiration rate in leaves, and the intercellular CO2 concentration accumulated under drought stress. Comparative transcriptome profiling revealed that under drought stress, leaf mesophyll tissue mainly stimulated the biosynthesis of amino acids, glutamic acid metabolism, and starch and sucrose metabolism. In particular, the arginine biosynthesis pathway was significantly enhanced to adapt to the water deficiency in leaf mesophyll tissue. However, in vascular tissue, the response to drought mainly involved ion transmembrane transport, hormone signal transduction, and depolymerization of proteasome. Concretely, ABA signaling and proteasome metabolism, which are involved in ubiquitin regulation, were changed under drought stress in KU50 leaf vascular tissue. Our work highlights that the leaf vasculature and mesophyll in cassava have completely different drought response mechanisms.
New late Oligocene rodent faunas from the Pannonian basin

Published: September 2021

AbstractThe rodent associations from the late Oligocene deposits of Ugljevik and Paragovo in the Pannonian basin are described. Pannoniamys paragovensis, a new genus and species of Spalacidae, is defined. The published data from a third late Oligocene locality in the area (Banovići) is included in the discussion of the changes in community structure through the time-interval studied. Although the composition of the rodent faunas studied differs, the dominating cricetid genus in all three associations is Deperetomys, a genus that appears in western Europe during the late middle Miocene. While the late Oligocene rodent record of central and southwestern Europe is characterised by endemic development, the regime in the Balkans seems to have been one of multiple immigrations and replacements. The late Oligocene age of the rodent fauna from Ugljevik estimated at about 26 Ma, provides a minimum age for the start of rifting in the Pannonian basin, some 6 Ma earlier than previously documented.
Analytical solution to pressure transient analysis in non-Newtonian/Newtonian fluids in naturally fractured composite reservoirs

Published: September 2021

AbstractDuring polymer flooding into the reservoir using shear-thinning non-Newtonian fluids, an interface exists between the in situ Newtonian crude oil in the reservoir and the injected polymer solution. This paper examines the application of non-Newtonian well test analysis techniques to develop an analytical solution to non-Newtonian/Newtonian fluids with different flow index composite reservoirs for estimating the interface boundary conditions in such reservoirs. Mathematical models were presented and solved analytically using the Laplace transform. The solution was inverted to real domain with the Stehfest algorithm (Stehfest Commun ACM, 1970). Solutions were obtained for three boundary conditions that are infinite acting, constant pressure and no-flow boundaries. New pressure and pressure derivative type curves are developed for naturally fractured reservoirs. A general solution was obtained, which is adaptable to the case of non-Newtonian/Newtonian fluid interface. Numerical examples are used to estimate the radius of investigation, reservoir and power-law flow parameters using type curve matching and Tiab’s direct synthesis technique.

Abstract
New threats posed by the emerging circulating variants of SARS-CoV-2 highlight the need to find conserved neutralizing epitopes for therapeutic antibodies and efficient vaccine design. Here, we identified a receptor-binding domain (RBD)-binding antibody, XG014, which potently neutralizes β-coronavirus lineage B (β-CoV-B), including SARS-CoV-2, its circulating variants, SARS-CoV and bat SARSr-CoV WIV1. Interestingly, antibody family members competing with XG014 binding show reduced levels of cross-reactivity and induce antibody-dependent SARS-CoV-2 spike (S) protein-mediated cell-cell fusion, suggesting a unique mode of recognition by XG014. Structural analyses reveal that XG014 recognizes a conserved epitope outside the ACE2 binding site and completely locks RBD in the non-functional “down” conformation, while its family member XG005 directly competes with ACE2 binding and position the RBD “up”. Single administration of XG014 is effective in protection against and therapy of SARS-CoV-2 infection in vivo. Our findings suggest the potential to develop XG014 as pan-β-CoV-B therapeutics and the importance of the XG014 conserved antigenic epitope for designing broadly protective vaccines against β-CoV-B and newly emerging SARS-CoV-2 variants of concern.

AbstractPediatric HIV infection remains a global health crisis with an estimated 150,000 new mother-to-child (MTCT) infections each year. Antiretroviral therapy (ART) has improved childhood survival, but only an estimated 53% of children worldwide have access to treatment. Adding to the health crisis is the neurological impact of HIV on the developing brain, in particular cognitive and executive function, which persists even when ART is available. Imaging studies suggest structural, connectivity, and functional alterations in perinatally HIV-infected youth. However, the paucity of histological data limits our ability to identify specific cortical regions that may underlie the clinical manifestations. Utilizing the pediatric simian immunodeficiency virus (SIV) infection model in infant macaques, we have previously shown that early-life SIV infection depletes the neuronal population in the hippocampus. Here, we expand on these previous studies to investigate the dorsolateral prefrontal cortex (dlPFC). A total of 11 ART-naïve infant rhesus macaques (Macaca mulatta) from previous studies were retrospectively analyzed. Infant macaques were either intravenously (IV) inoculated with highly virulent SIVmac251 at ~1 week of age and monitored for 6–10 weeks or orally challenged with SIVmac251 from week 9 of age onwards with a monitoring period of 10–23 weeks post-infection (19–34 weeks of age), and SIV-uninfected controls were euthanized at 16–17 weeks of age. Both SIV-infected groups show a significant loss of neurons along with evidence of ongoing neuronal death. Oral- and IV-infected animals showed a similar neuronal loss which was negatively correlated to chronic viremia levels as assessed by an area under the curve (AUC) analysis. The loss of dlPFC neurons may contribute to the rapid neurocognitive decline associated with pediatric HIV infection.
The Limits of Marginality
Authors: Heathcote Andrew , Matzke Dora 
Published: September 2021

AbstractThe “marginality principle” for linear regression models states that when a higher order term is included, its constituent terms must also be included. The target article relies on this principle for the fixed-effects part of linear mixed models of ANOVA designs and considers the implication that if extended to combined fixed-and-random-effects models, model selection tests specific to some fixed-effects ANOVA terms are not possible. We review the basis for this principle for fixed-effects models and delineate its limits. We then consider its extension to combined fixed-and-random-effects models. We conclude that we have been unable to find in the literature, including the target article, and have ourselves been unable to construct any satisfactory argument against the use of incomplete ANOVA models. The only basis we could find requires one to assume that it is not possible to test point-null hypotheses, something we disagree with, and which we believe is incompatible with the Bayesian model-selection methods that are the basis of the target article.
Investigating preferences in art collecting: the case of the François Pinault Collection
Authors: Codignola Federica , Mariani Paolo 
Published: September 2021

AbstractThis article focuses on private art collections that play a relevant role on the art market while reducing its information asymmetry. Knowledge of how art consumers such as private art collectors show preferences for specific artworks may allow to identify collecting patterns based on the preference of some artworks’ signs. Understanding these patterns is essential for evaluating the impact of art collectors on the art market. The evolution of the art market shows complex consumption systems that shape the cognition and behavior of actors such as private art collectors. Consequently, to be a key art collector and to progress as such in today’s art world implies a constant reinterpretation about what it means to consume and to collect art. This paper explores the collection of one of the most important art collectors in the world, the French tycoon François Pinault. More precisely, his background as a key collector was examined, and a number of preferences toward particular signs which connote his collected artworks were identified. All the collected artworks were observed through a descriptive data analysis of the Pinault Collection’s exhibition catalogues, published from 2006 to 2015, enforced by the statistical decision tree classifier. Results show how the Pinault Collection is shaped by collecting preferences that can be described as collecting patterns. As a preeminent collector and owner of one of the two major auction houses in the world, Pinault’s consumption preferences and decisions may impact the art market, for instance through signals and by influencing other art market players or the artists’ careers.

Abstract
We report on a power-scalable sub-100-fs laser in the 2-μm spectral range using a Tm3+-doped ‘mixed’ (Lu,Sc)2O3 sesquioxide ceramic as an active medium. Pulses as short as 58 fs at 2076 nm with an average output power of 114 mW at a pulse repetition rate of approximately 82.9 MHz are generated by employing single-walled carbon nanotubes as a saturable absorber. A higher average power of 350 mW at 2075 nm is obtained at the expense of the pulse duration (65 fs). A maximum average power of 486 mW is achieved for a pulse duration of 98 fs and an optical conversion efficiency of 22.3%, representing the highest value ever reported from sub-100-fs mode-locked Tm lasers.
Conjuring Caliban's Woman: Moving beyond Cinema's Memory of Man in Praise House (1991)
Authors: Dozier Ayanna 
Published: September 2021

AbstractJulie Dash's experimental short film, Praise House (1991), situates conjuring as both a narrative and formal device to invent new memories around Black womanhood that exceed our representation within the epistemes of Man. I view Praise House as an example of conjure-cinema with which we can evaluate how Black feminist filmmakers, primarily working in experimental film, manipulate the poetic structure and aesthetics of film to affect audiences rather than rely on representational narrative alone. Following the scholarship of Sylvia Wynter, I use Man to refer to the representational body of the Western episteme that defines value through mass accumulation. It is through Wynter's scholarship that we find the ontological emancipation from Man that is Caliban's woman, who represents discourse beyond our normative, colonial mode of feeling/knowing/being. Through an analysis of Praise House that foregrounds film's ability to generate affect via its aesthetics, this article argues that aesthetics can similarly enact the same power of conjure as found in Praise House's narrative, and as such conjures an epistemological rupture to our normative order that is Caliban's woman.
Sanctuary Cities in Europe? A Policy Survey of Urban Policies in Support of Irregular Migrants
Authors: Kaufmann David , Räss Nora , Strebel Dominique , Sager Fritz 
Published: September 2021

AbstractIrregular migrants tend to live in dense urban settings. Cities therefore formulate various policies in support of irregular migrants. Given the US phenomenon of sanctuary cities, the study of these policies has been rather US-centric so far. This letter examines urban policies in support of irregular migrants in Europe's 95 largest cities. Only 27 per cent of European cities formulate these types of policies. We discovered two relevant policy categories: status and services. Only five cities formulate policies that aim to award irregular migrants with a (more) secure status, and 24 cities formulate policies that facilitate access to city services. Our mixed-methods analysis suggests that status policies take advantage of policy-making discretion whereas service policies hinge on the availability of local resources. Yet, there are no simple explanations for the observed policy diversity that is the product of place-based policy-making.
THE BEAUTY OF FAILURE: HAMARTIA IN ARISTOTLE'S POETICS
Authors: Vinje Hilde 
Published: September 2021

AbstractIn Poetics 13, Aristotle claims that the protagonist in the most beautiful tragedies comes to ruin through some kind of ‘failure’—in Greek, ἁμαρτία. There has been notorious disagreement among scholars about the moral responsibility involved in ἁμαρτία. This article defends the old reading of ἁμαρτία as a character flaw, but with an important modification: rather than explaining the hero's weakness as general weakness of will (ἀκρασία), it argues that the tragic hero is blinded by temper (θυμός) or by a pursuit for fine, good and desirable things—that is, by what may be labelled ‘qualified’ weakness of will. The upshot is that ἁμαρτία ends up as being less blameworthy than ‘proper’ ἀκρασία, but still explains why morally outstanding people are unsuitable for the most beautiful tragedies.
A pilot study of dialectical behaviour therapy skills training for autistic adults
Authors: Ritschel Lorie A. , Guy Lisa , Maddox Brenna B. 
Published: September 2021

AbstractBackground:Autism spectrum disorder (ASD) is a common and lifelong neurodevelopmental disorder with the hallmark features of social impairment and restricted and repetitive patterns of behaviour. Individuals with ASD often experience co-occurring mental health difficulties, some of which may obfuscate the ASD features themselves. Although there is a high need for mental health services for autistic adults, there are surprisingly few evidence-based treatments (EBTs) available; moreover, many mental health practitioners who are well-trained in EBTs shy away from treating autistic individuals due to lack of training in ASD.Aims:The aim of the current study was to evaluate the feasibility and acceptability of dialectical behaviour therapy skills training (DBT-ST) in a sample of autistic adults without intellectual disability.Method:Sixteen adults with ASD were recruited from a treatment waiting list to enrol in this study, which included 24 weeks of DBT-ST delivered in a group setting. Feasibility and acceptability were assessed using retention and attendance data and a participant satisfaction questionnaire.Results:Retention (81.3%) and attendance data (mean 87.5%) provided support for the feasibility of this intervention. Overall satisfaction ratings were high (mean 4.5 out of 5), and participants reported that they felt that DBT-ST would probably be helpful for others with ASD (mean 4.5 out of 5).Conclusions:The study findings provide preliminary evidence of (1) the feasibility of providing DBT-ST for autistic adults in community-based clinics, and (2) the perceived benefit of DBT-ST for this under-served population. Recommended modifications to the standard DBT-ST materials are discussed.

AbstractObjectives:In this study, socio-economic factors associated with Afghan refugee households’ food insecurity, anxiety and uncertainty, insufficient quality and food intake were determined.Design:Household Food Insecurity Assess Scale measurement was applied to assess food insecurity, anxiety and uncertainty, insufficient quality and insufficient food intake. Descriptive analysis and multivariable regression models were used to determine the associated factors.Setting:The study was carried out in urban areas of Tehran province in Iran.Participants:To collect data, interviews were conducted among 317 Afghan households. The questionnaire was administered via face-to-face interviews to either the breadwinner of the selected households or a member who could respond on behalf of the household.Results:About 11·3 % of Afghan households who resettled in Tehran province were food secure, while 11·7 % were marginally, 40·7 % moderately and 36·3 % severely food insecure. Economic and financial factors were inversely and significantly associated with food insecurity. Employment, income, distance from the central market and personal saving were inversely associated with food insecurity, while other determinants, including the length of living time in Tehran, house type and the number of male and female children, had a direct association with food insecurity.Conclusions:The associations of socio-economic factors with three categories of food insecurity differed. Elimination of occupation bans that the Iranian government imposes on refugees provides simple access to financial supports like long-term loans, and opening a bank account for refugees will benefit both Iranians and refugees.
