Published: March 2021

AbstractThe current collector fracture failure of lithium-ion batteries (LIBs) occurs during its winding production process frequently, and the consequent damages are usually large, but little research has been conducted on this phenomenon. This work stems from the difficulty and obstacles in the winding process of actual production of LIBs. The fracture failure of the current collectors is easily caused by the evolution and mutation of the mechanical behavior during the winding process, resulting in safety hazards and poor efficiency. The purpose of this work is to reveal the evolution and distribution mechanism of circumferential strain of the current collectors on the fracture failure under the constraint of winding process. Experimental tests, finite element calculations and theoretical model are used to study the evolution and distribution of circumferential strain. The dynamic evolution process of circumferential strain is tested accurately, and the mechanism of fracture failure of current collectors is revealed. The criterion for current collector strength is proposed based on the results of strain analysis and SEM observation.
Anarchy’s Neighborhoods: the Formation of a Quadriplex Urban Ecology
Authors: Katz Jack 
Published: March 2021

AbstractIn each of four nearby city areas, residents orient to local centers of collective activity in different geographic patterns. In a “perimeter” neighborhood, residents and outsiders are drawn to religious and retail organizations located on streets that form a rectangle. In an “intersection” neighborhood, residents are most visible to each other at an agglomeration of stores and services located where two high traffic streets cross. Residents of an “in-between” area travel to socio-economically and culturally different neighborhoods centered in all directions elsewhere. In a “contested” geography, rival organizations disagree over who, living where, for what purposes, has the right to define the neighborhood’s boundaries and social identity. These different social ecologies took shape without coordination yet became an interdependent, quadriplex set. After 1965, a series of retreats in government control of local social life created unprecedented opportunities for intermediaries who reshaped the social landscape with new businesses, cultural institutions, and interpretations of neighborhood identity. This case study revives the “collective action” explanations of the “Chicago School” by showing how urban social ecology was transformed in the late twentieth century as people of different generations and in different geographic areas interacted indirectly, creating durable neighborhood patterns without centralized, top-down leadership from business or government, in response to locally recognized affordances of anarchy.
Divine Gütigkeit, Divine Güte: Kant on an Ancient Query
Authors: Kravitz Amit 
Published: March 2021

AbstractIn his essay on theodicy, Kant explicitly claims that while the disproportion between crime and punishment poses a theodicean challenge concerning God’s justice, the suffering of the righteous is compatible with God’s justice [Gerechtigkeit], goodness [Gütigkeit], and holiness [Heiligkeit]. In light of this, Kant’s reason for addressing the book of Job in this context is puzzling. However, the location of Job’s story in the text reveals that Job’s suffering is rendered relevant only concerning the relation between two of God’s moral attributes: goodness as subordinated to holiness, i.e., God’s benevolence [Güte]. Implications concern the difference between ‘authentic’ and ‘doctrinal’ theodicy.
Emergency evacuation simulation of commercial aircraft
Authors: Gobbin Andreas , Khosravi Raman , Bardenhagen Andreas 
Published: March 2021

AbstractIn order to receive certification approval for new products, aircraft manufacturers have to comply with the specifications regarding cabin evacuation. In case of real evacuation trials, agent-based simulation can be deployed, as they are a less cost-intensive mean of analysing passenger behaviour during the evacuation of commercial aircraft. This paper aims at examining the suitability of agent-based simulation software to reproduce passenger behaviour during evacuation processes. For this purpose, the algorithms and methods of the software PATHFINDER are introduced. Besides, the cabin of a single aisle aircraft is reconstructed in a high-density configuration using software-specific tools. A representative passenger distribution is implemented according to EASA regulations. Evacuation simulations for a single-aisle aircraft are conducted taking EASA standards into account. The effect of vital parameters such as walking speed, body dimension, conflict behaviour, collision response, acceleration time and exit allocation on evacuation times are examined. Results are discussed and examined for plausibility in order to determine whether evacuation simulations of commercial aircraft are possible using agent-based simulation software.
Facial expression recognition on a quantum computer
Authors: Mengoni Riccardo , Incudini Massimiliano , Di Pierro Alessandra 
Published: March 2021

AbstractWe address the problem of facial expression recognition and show a possible solution using a quantum machine learning approach. In order to define an efficient classifier for a given dataset, our approach substantially exploits quantum interference. By representing face expressions via graphs, we define a classifier as a quantum circuit that manipulates the graphs adjacency matrices encoded into the amplitudes of some appropriately defined quantum states. We discuss the accuracy of the quantum classifier evaluated on the quantum simulator available on the IBM Quantum Experience cloud platform, and compare it with the accuracy of one of the best classical classifier.
Quantum Divide and Compute: Exploring the Effect of Different Noise Sources

Published: March 2021

AbstractOur recent work (Ayral et al. in Proceedings of IEEE computer society annual symposium on VLSI, ISVLSI, pp 138–140, 2020. 10.1109/ISVLSI49217.2020.00034) showed the first implementation of the Quantum Divide and Compute (QDC) method, which allows to break quantum circuits into smaller fragments with fewer qubits and shallower depth. This accommodates the limited number of qubits and short coherence times of quantum processors. This article investigates the impact of different noise sources—readout error, gate error and decoherence—on the success probability of the QDC procedure. We perform detailed noise modeling on the Atos Quantum Learning Machine, allowing us to understand tradeoffs and formulate recommendations about which hardware noise sources should be preferentially optimized. We also describe in detail the noise models we used to reproduce experimental runs on IBM’s Johannesburg processor. This article also includes a detailed derivation of the equations used in the QDC procedure to compute the output distribution of the original quantum circuit from the output distribution of its fragments. Finally, we analyze the computational complexity of the QDC method for the circuit under study via tensor-network considerations, and elaborate on the relation the QDC method with tensor-network simulation methods.
Urban Living Labs, Circular Economy and Nature-Based Solutions: Ideation and Testing of a New Soil in the City of Turin Using a Multi-stakeholder Perspective

Published: March 2021

AbstractIn the attempt to foster circular economy (CE), cities are increasingly adopting urban living labs (ULLs) as sites of co-production aimed at testing alternative solutions based on the reuse of products, reduction of consumption and recycling of materials. Taking this perspective, our study adopts an exploratory research design to discover the pragmatic implications emerging from a case study. The City of Turin joined proGIreg, a European project that entails the regeneration of former industrial districts by means of nature-based solutions (NBS). Ranging from aquaponics to green roofs, seven NBS have been experimented in Turin, which rely on the use of natural systems to tackle social, economic and environmental challenges efficiently and sustainably. Among them, the most promising is related to the production and test of the ‘new soil’, a blend obtained by mixing earth materials coming from construction sites with compost, zeolites and mycorrhizae. The case herein presented is interesting to analyse for the multi-stakeholder management setting used, where public institutions, private companies, research institutions, citizens and associations collaborated in the co-creation and testing phase of the NBS. Consequently, the data collected through participant observation and direct interviews allow researchers to describe multi-stakeholders’ dynamics and how they work. Thus, this paper narrates a micro-contextual experience while providing a critique. Results include an analysis of the unique combination of different stakeholders, which strongly impacted on the management and the effectiveness of the entire project. By consequence, the paper offers both theoretical contributions to the relational branch of stakeholder theory and practical evidence in demonstrating the importance of the relational branch of the theory over a more traditional transactional view.
PRICING LONGEVITY-LINKED SECURITIES IN THE PRESENCE OF MORTALITY TREND CHANGES
Authors: Freimann Arne 
Published: March 2021

ABSTRACTEven though the trend in mortality improvements has experienced several permanent changes in the past, the uncertainty regarding future mortality trends is often left unmodeled when pricing longevity-linked securities. In this paper, we present a stochastic modeling framework for the valuation of longevity-linked securities which explicitly considers the risk of random future changes in the long-term mortality trend. We construct a set of meaningful probability distortions which imply equivalent risk-adjusted pricing measures under which the basic model structure is preserved. Inspired by risk-based capital requirements for (re)insurers, we also establish a cost-of-capital pricing approach which then serves as the appropriate reference framework for finding a reasonable range for the market price of longevity risk. In a numerical application, we demonstrate that our model produces plausible risk loadings and show that a greater proportion of the risk loading is allocated to longer maturities when the risk of random future mortality trend changes is adequately modeled.

AbstractPurpose:The aim of the current study was to investigate the prevalence of face mask wearing among different groups of people in south Iran. We also investigated the associations between mask wearing hesitancy and various factors.Methods:We surveyed a sample (convenience sampling) of 5 groups of people: general population, people with epilepsy, people with diabetes mellitus (DM), people with cardiac problems, and people with psychiatric problems. The survey included 4 general questions (age, sex, education, and medical/psychiatric problem) and 4 coronavirus disease 2019 (COVID-19)-specific questions (contracting COVID-19, relatives with COVID-19, wearing a face mask while in crowded places, and the frequency of daily hand washings).Results:A total of 582 people (153 people with epilepsy, 127 patients with DM, 98 people with cardiac problems, 96 patients with psychiatric disorders, and 108 healthy individuals) participated. Twenty-eight (4.8%) people expressed that they do not wear a face mask when at crowded places. A lower education and less frequent daily hand washings had associations with mask wearing hesitancy.Conclusions:Mask wearing hesitancy is a concern during a respiratory viral disease pandemic. Paying attention to personal variables, especially if they are modifiable (eg, education and hygiene), is probably productive and practical in promoting mask wearing culture.
“Fraudonomics”: Cartooning against Structural Adjustment in Togo
Authors: Frisch Robin 
Published: March 2021

AbstractThis article offers a sensitive reading of oppositional political cartoons in Togo in the early 1990s, during the period of structural adjustment, which was accompanied by the swift reversal of democratizing trends and the restoration of authoritarian rule. Togolese satirists perceived this moment as a moment of “fraudonomics”, thus contesting rampant corruption and clientelism in politics. They poked fun at the president, local politicians, businesspeople, and bureaucrats of the international institutions. The article begins by examining the making of satirical newspapers with a focus on the biographies of the satirists. As students, they started out on the adventure of publication with their own money and learned most of their drawing and printing techniques as work progressed. Secondly, an analysis of the readership shows that, although the satirical newspapers were a crucial element of the media in the early 1990s, it was mostly an elitist and urban phenomenon. The third section analyses the changing visual repertoire of contention through in-depth analysis of four selected caricatures.

Abstract
A survey on Anisakis simplex (sensu stricto (s.s.)) from blue whiting, Micromesistius poutassou, in the north-eastern Atlantic Ocean revealed the occurrence of high infection levels of third larval stages in visceral organs and flesh. Larvae were genetically identified with a multilocus approach as A. simplex (s.s.). Histochemical, immunohistochemical and ultrastructural observations were conducted on 30 M. poutassou specimens. Gonads, pyloric caeca and flesh harboured encapsulated larvae of A. simplex (s.s.) but no intense host reaction was encountered around the parasite in the above organs. In the liver, the most infected organ, the larvae co-occurred with the coccidian Goussia sp. Within the granuloma around the A. simplex (s.s.) larvae, two concentric layers were recognized, an inner mostly comprising electron-dense epithelioid cells and an outer layer made of less electron-dense epithelioid cells. Macrophages and macrophage aggregates (MAs) were abundant out of the granulomas, scattered in parenchyma, and inside the MAs, the presence of engulfed Goussia sp. was frequent. In liver tissue co-infected with Goussia sp. and A. simplex (s.s.), hepatocytes showed cytoplasmic rarefaction and acute cell swelling. Results suggest that the host-induced encapsulation of A. simplex (s.s.) larvae is a strategic compromise to minimize collateral tissue damage around the larval infection sites, to facilitate the survival of both parasite and host.
Telecommunication line infrastructure and the Arctic environment: past, present and future
Authors: Saunavaara Juha , Kylli Ritva , Salminen Mirva 
Published: March 2021

AbstractThis article concentrates on the interconnected past, present and future of telecommunications and the environment in the Arctic. It brings together discussions on the natural environment, sustainable development and connectivity in and through the Arctic and focuses on fixed-line infrastructure. This study builds on the theoretical literature on infrastructure, infrastructuring and pipeline ecologies and demonstrates how the peculiar features of the Arctic, such as coldness, snow and ice, ground frost and permafrost affect telecommunication lines, and how this infrastructure impacts the environment in which it is built. Similarly, the environmental conditions, paired with long distances, small populations and limited economic opportunities, affect the infrastructuring processes and the selection of technologies, as well as their spatial extent, quality and the speed of their expansion. While the construction of telecommunication lines supports the exploitation of natural resources in and beyond the different parts of the circumpolar North, it also plays a role in the observation and protection of the Arctic.
A ξ-weak Grothendieck compactness principle
Authors: BEANLAND KEVIN , CAUSEY RYAN M. 
Published: March 2021

AbstractFor 0 ≤ ξ ≤ ω1, we define the notion of ξ-weakly precompact and ξ-weakly compact sets in Banach spaces and prove that a set is ξ-weakly precompact if and only if its weak closure is ξ-weakly compact. We prove a quantified version of Grothendieck’s compactness principle and the characterisation of Schur spaces obtained in [7] and [9]. For 0 ≤ ξ ≤ ω1, we prove that a Banach space X has the ξ-Schur property if and only if every ξ-weakly compact set is contained in the closed, convex hull of a weakly null (equivalently, norm null) sequence. The ξ = 0 and ξ= ω1 cases of this theorem are the theorems of Grothendieck and [7], [9], respectively.
Education and Social Capital
Authors: Apfeld Brendan , Coman Emanuel , Gerring John , Jessee Stephen 
Published: March 2021

AbstractEarly research suggested that education was a major factor in structuring rates of political participation and social capital. More recent work based on experimental or quasi-experimental evidence offers mixed findings. In this study, we enlist a unique research setting in Romania, where passing the baccalaureate is required for entrance into university, setting up the occasion for a fuzzy RD design. The sample is drawn from a cross section of Romanians whose scores fall just above or below the cutoff. Because the sample is large and the measurement of exam scores are fine-grained, it is plausible to regard the outcome as continuous at the cutoff. Because the number of exam takers is enormous, we are able to focus on a very narrow bandwidth. The assumption of as-if random assignment is, therefore, plausible. We find that university attendance in Romania increases social capital as measured by our composite index, corroborating the main hypothesis.
Long and Active Magnetopause Reconnection X‐Lines During Changing IMF Conditions

Published: March 2021

AbstractThe magnetic reconnection process at the Earth's magnetopause is observed at various times and places as either anti‐parallel or component reconnection. The two scenarios are combined in a model known as the Maximum Magnetic Shear model, which predicts the location of long and continuous reconnection X‐lines across the dayside magnetopause along the ridge of maximum magnetic shear. This study investigates a Magnetospheric Multiscale Mission (MMS) magnetopause encounter where the spacecraft had repeated contact with the boundary layers for about 40 min. While in contact with the magnetopause boundary layers, the Interplanetary Magnetic Field (IMF) slowly and continuously rotated, magnetically connecting the MMS spacecraft to different sections along an extended dayside reconnection X‐line. These magnetic connection points slide along component reconnection tilted X‐lines and also connect several times to the anti‐parallel section of the magnetopause X‐line. Despite the continuously changing IMF conditions, each magnetopause boundary layer encounter shows accelerated ion beams, indicating an active reconnection X‐line at the magnetopause that covers a length of about 20 RE.
Surface Thermal Structure and Variability of Upwelling Shadows in the Gulf of Arauco, Chile

Published: March 2021

AbstractThe upwelling shadow in the Gulf of Arauco (GA) is studied using 15 years of daily satellite images of Sea Surface Temperature (SST) from Geostationary Operational Environmental Satellites (GOES), as well as heat flux and wind data from the ERA5 reanalysis product. An Upwelling Shadow Index (USI) is developed based on the SST differences between the GA and the region off Punta Lavapie (PL) farther offshore, characterized by active upwelling. USI values greater than 0.91°C and SST differences less than 1.1°C, correspond to an upwelling shadow event. These cases occurred 10.29% of the time and were more frequent in spring/summer during events of upwelling‐favorable winds with strong cyclonic wind stress curl, interspersed with wind relaxations. Multiple correlations between USI and wind stress curl and solar radiation showed an r2 = 40%–80% for some summer months. Most events persisted for only 1 day (53%), whereas 34% of upwelling shadow events lasted between 2 and 4 days and 9% of events were longer than 4 days. Water residence times as long as 15 days were observed in the GA during upwelling shadow events. During southerly wind relaxation (less than 2 days), cold surface waters flowing north from PL curved onshore and entered the GA from the north, weakening the thermal gradient between PL and GA and the upwelling shadow. Long periods of wind relaxation (at least 1 week) resulted in the dissipation of the thermal gradient due to the warming of offshore waters.
Upscaling Sediment‐Flux‐Dependent Fluvial Bedrock Incision to Long Timescales
Authors: Turowski Jens M. 
Published: March 2021

AbstractFluvial bedrock incision is driven by the impact of moving bedload particles. Mechanistic, sediment‐flux‐dependent incision models have been proposed, but the stream power incision model (SPIM) is frequently used to model landscape evolution over large spatial and temporal scales. This disconnect between the mechanistic understanding of fluvial bedrock incision on the process scale, and the way it is modeled on long time scales presents one of the current challenges in quantitative geomorphology. Here, a mechanistic model of fluvial bedrock incision that is rooted in current process understanding is explicitly upscaled to long time scales by integrating over the distribution of discharge. The model predicts a channel long profile form equivalent to the one yielded by the SPIM, but explicitly resolves the effects of channel width, cross‐sectional shape, bedrock erodibility, and discharge variability. The channel long profile chiefly depends on the mechanics of bedload transport, rather than bedrock incision. In addition to the imposed boundary conditions specifying the upstream supply of water and sediment, and the incision rate, the model includes four free parameters, describing the at‐a‐station hydraulic geometry of channel width, the dependence of bedload transport capacity on channel width, the threshold discharge of bedload motion, and reach‐scale cover dynamics. For certain parameter combinations, no solutions exist. However, by adjusting the free parameters, one or several solutions can usually be found. The controls on and the feedbacks between the free parameters have so far been little studied, but may exert important controls on bedrock channel morphology and dynamics.
