‘Seeing with Empty Eyes’: a systems approach to understand climate change and mental health in Bangladesh
Authors: Hayward Gemma , Ayeb-Karlsson Sonja 
Published: March 2021

AbstractBangladesh’s unique climate vulnerability is well-investigated but the mental health impacts of climate change remain relatively unexplored. Three databases were searched for English primary qualitative studies published between 2000 and 2020. Out of 1202 publications, 40 met the inclusion criteria. This systematic review applies a systems approach to further understand Bangladesh’s ‘climate-wellbeing’ network. The literature indicates diverse factors linking environmental stress and mental ill-health including four key themes: (1) post-hazard mental health risks, (2) human (im)mobility, (3) social tension and conflict, and (4) livelihood loss and economic hardship. This systems analysis also revealed that people’s mental wellbeing is strongly mediated by socio-economic status and gender. The article illustrates how multiple pathways may amplify stress, anxiety, violence, and psychological damage. Greater recognition of the ‘climate-wellbeing’ connections, and incorporation of mental health in current climate action and policy frameworks, will be an effective way to achieve a more sustainable future.
Minding mathematicians’ discourses in investigations of their feedback on students’ proofs: a case study
Authors: Kontorovich Igor’ 
Published: March 2021

AbstractThis article presents a research apparatus for investigating and making sense of stories that emerge from feedback that mathematicians provide on students’ proofs. Using the commognitive framework, the notion of didactical discourse on proof is developed as a lens for conceptualizing mathematicians’ practice of feedback provision. The notion is accompanied by a tentative organizational frame, within which didacticians and mathematicians can operate as partners. The methodological affordances of this apparatus are illustrated with a case study of a research topologist, who taught a small, graduate course in topology. The emerged characteristics of her feedback and discourse are situated in the literature and used to sketch future research avenues.
Brain cancer incidence rates and the presence of nuclear reactors in US states: a hypothesis-generating study
Authors: Williamson Mark R. , Klug Marilyn G. , Schwartz Gary G. 
Published: March 2021

Abstract
Background
The etiology of brain cancer is poorly understood. The only confirmed environmental risk factor is exposure to ionizing radiation. Because nuclear reactors emit ionizing radiation, we examined brain cancer incidence rates in the USA in relation to the presence of nuclear reactors per state.

Methods
Data on brain cancer incidence rates per state for Whites by sex for three age groups (all ages, 50 and older, and under 50) were obtained from cancer registries. The location, number, and type of nuclear reactor, i.e., power or research reactor, was obtained from public sources. We examined the association between these variables using multivariate linear regression and ANOVA.

Results
Brain cancer incidence rates were not associated with the number of nuclear power reactors. Conversely, incidence rates per state increased with the number of nuclear research reactors. This was significant for both sexes combined and for males in the ‘all ages’ category (β = 0.08, p = 0.0319 and β = 0.12, p = 0.0277, respectively), and for both sexes combined in the’50 and older’ category (β = 0.18, p = 0.0163). Brain cancer incidence rates for counties with research reactors were significantly higher than the corresponding rates for their states overall (p = 0.0140). These findings were not explicable by known confounders.

Conclusions
Brain cancer incidence rates are positively associated with the number of nuclear research reactors per state. These findings merit further exploration and suggest new opportunities for research in brain cancer epidemiology.
Population and Climate Change: Consensus and Dissensus among Demographers
Authors: van Dalen Hendrik P. , Henkens Kène 
Published: March 2021

AbstractWhat role does population play in thinking about the problem of climate change and some of its solutions? In a survey conducted between February and April 2020, we asked European demographers to state their views on the relationship between climate change and population developments, and asked them to rate their concern about climate change and other socio-demographic issues. We found that climate change is at the top of the list of demographers’ concerns, but that their sense of urgency with respect to taking action to redress global warming is not matched by their belief that population policy can make a crucial difference in reducing CO2emissions: demographers are highly divided on the question whether the global population size should be reduced to lower CO2emissions, as well as on the question whether family planning is an effective policy instrument.

Published: March 2021

AbstractPurposeThere is a lack of results on long-term effects of return to work interventions. We previously reported that an inpatient multimodal occupational rehabilitation program (I-MORE) was more effective in reducing sickness absence and facilitating return to work (RTW) at 12 months follow-up compared to an outpatient program that consisted mainly of Acceptance and Commitment Therapy (O-ACT). We now report the 2-year outcome data.MethodsA randomized clinical trial with parallel groups. Participants were 18–60 years old, sick listed with musculoskeletal, common mental or general/unspecified disorders. I-MORE lasted 3.5 weeks and consisted of ACT, physical training and work-related problem solving. O-ACT consisted mainly of 6 weekly sessions (2.5 h. each) of ACT in groups. Outcomes were cumulated number of days on medical benefits and time until sustainable RTW (1 month without medical benefits) during 2-years of follow-up, measured by registry data.ResultsFor the 166 randomized participants, the median number of days on medical benefits was 159 (IQR 59–342) for I-MORE vs 249 days (IQR 103–379; Mann–Whitney U test, p = 0.07), for O-ACT. At 2 years, 40% in I-MORE received long-term benefits (work assessment allowance) vs 51% in O-ACT. The crude hazard ratio (HR) for sustainable RTW was 1.59 (95% CI 1.04–2.42, p = 0.03) and the adjusted HR 1.77 (95% CI 1.14–2.75, p = 0.01), in favor of I-MORE.ConclusionsThe 2-year outcomes show that I-MORE had long-term positive effects on increasing work participation for individuals sick listed with musculoskeletal and mental disorders. Further follow-up and economic evaluations should be performed.
Passive and active vibration isolation under isolator-structure interaction: application to vertical excitations
Authors: Pérez-Aracil J. , Pereira E. , Díaz Iván M. , Reynolds P. 
Published: March 2021

AbstractThis work studies the influence of a vibration isolator on the response of a flexible base structure. Two strategies are compared: passive and active vibration isolation (PVI, AVI). Although the multiple advantages of AVI over PVI techniques are well known, their effect in the base structure has not to date been compared. This interaction has an important role in the performance of the general control system, especially when the vibration isolation system is not the only system on the base structure or when there are multiple isolators working simultaneously on it. In addition, the structural serviceability of the base structure can also be affected. The analysis of the vibration isolation problem is made from a wide perspective, including the effect that isolator has on the base structure. Hence assuming the base structure is a non-rigid system. The effect of the isolation system on the base response is studied for an extensive range of base structures, thus showing different possible scenarios. The influence is quantified by comparing the peak magnitude response of the base when both passive and active vibration isolation techniques are used. The theoretical results have been corroborated by undertaking experimental tests on a full-scale laboratory structure.
Effect of mass distribution on curving performance for a loaded wagon
Authors: Zhang Duo , Tang Yinying , Peng Qiyuan , Dong Chunjiao , Ye Yunguang 
Published: March 2021

AbstractThe location of wagon gravity center for a loaded wagon is underestimated in a vehicle–track coupled system. The asymmetric wheel load distribution due to loading offset significantly affects the wheel-rail contact state and seriously deteriorates the curving performance in conjunction with the height of gravity center and cant deficiency. Optimizing the location of gravity center and cruising velocity, therefore, is of interest to prevent the derailment and promote the transport capacity of railway wagons. This study aims to reveal the three-dimensional influencing mechanism of mass distribution on vehicle curving performance under different velocities. The wheel unloading ratio is regarded as the evaluation index. A simplified quasi-static model is established considering essential assumptions to highlight the influence of lateral and vertical offset on curving performance. For a more accurate description, the MBS models with various locations of wagon gravity center are built and then negotiate curves in different simulation cases. The simulation results reveal that the distribution of wheel unloading ratio determined by loading offset is like contour lines of ‘basin’. Based on the conclusions of quasi-static analysis and dynamics simulations, the regression equation is proposed and the fitting parameters are calculated for each simulation case. This paper demonstrates the necessity of optimizing the location of wagon gravity center according to the running condition and offers a novel strategy to load and transport the cargo by railway wagons.

Numerical Investigation of Successively Nucleating Bubbles During Subcooled Flow Boiling of FC-72 in Microgravity
Authors: Franz Benjamin , Sielaff Axel , Stephan Peter 
Published: March 2021

AbstractFor the present study numerical simulations of subcooled flow boiling of FC-72 in microgravity have been conducted to accompany boiling experiments performed in microgravity on the International Space Station (ISS). The numerical domain represents the geometry of the experimental test cell. For all simulations the open source framework OpenFOAM was employed, including extensions to the interFoam solver, which have been developed at the authors’ institute. A reference case has been defined applying intermediate values from the experimental parameter range as system parameters. This case has been examined thoroughly with regards to hydrodynamic phenomena and heat transfer during multiple, successive bubble cycles. Based on this reference case, the system parameters flow velocity, input heat flux, pre-heating time, and subcooling of the liquid bulk have been varied, and the impact of these quantities on bubble growth and movement as well as heat transfer have been studied. It was found, that an increased flow rate as well as increased subcooling lead to smaller bubbles and increased time between subsequent nucleations. A high input heat flux, an increased pre-heating time, and a decreased subcooling lead to a rapid cycle of bubble nucleation and coalescence.
“The street is ours”. A comparative analysis of street trading, Covid-19 and new street geographies in Harare, Zimbabwe and Kisumu, Kenya
Authors: Kiaka Richard , Chikulo Shiela , Slootheer Sacha , Hebinck Paul 
Published: March 2021

AbstractThis collaborative and comparative paper deals with the impact of Covid-19 on the use and governance of public space and street trade in particular in two major African cities. The importance of street trading for urban food security and urban-based livelihoods is beyond dispute. Trading on the streets does, however, not occur in neutral or abstract spaces, but rather in lived-in and contested spaces, governed by what is referred to as ‘street geographies’, evoking outbreaks of violence and repression. Vendors are subjected to the politics of municipalities and the state to modernize the socio-spatial ordering of the city and the urban food economy through restructuring, regulating, and restricting street vending. Street vendors are harassed, streets are swept clean, and hygiene standards imposed. We argue here that the everyday struggle for the street has intensified since and during the Covid-19 pandemic. Mobility and the use of urban space either being restricted by the city-state or being defended and opened up by street traders, is common to the situation in Harare and Kisumu. Covid-19, we pose, redefines, and creates ‘new’ street geographies. These geographies pivot on agency and creativity employed by street trade actors while navigating the lockdown measures imposed by state actors. Traders navigate the space or room for manoeuvre they create for themselves, but this space unfolds only temporarily, opens for a few only and closes for most of the street traders who become more uncertain and vulnerable than ever before, irrespective of whether they are licensed, paying rents for vending stalls to the city, or ‘illegally’ vending on the street.
$$\Gamma $$-Robust electricity market equilibrium models with transmission and generation investments
Authors: Çelebi Emre , Krebs Vanessa , Schmidt Martin 
Published: March 2021

AbstractWe consider uncertain robust electricity market equilibrium problems including transmission and generation investments. Electricity market equilibrium modeling has a long tradition but is, in most of the cases, applied in a deterministic setting in which all data of the model are known. Whereas there exist some literature on stochastic equilibrium problems, the field of robust equilibrium models is still in its infancy. We contribute to this new field of research by considering $$\Gamma $$
Γ
-robust electricity market equilibrium models on lossless DC networks with transmission and generation investments. We state the nominal market equilibrium problem as a mixed complementarity problem as well as its variational inequality and welfare optimization counterparts. For the latter, we then derive a $$\Gamma $$
Γ
-robust formulation and show that it is indeed the counterpart of a market equilibrium problem with robustified player problems. Finally, we present two case studies to gain insights into the general effects of robustification on electricity market models. In particular, our case studies reveal that the transmission system operator tends to act more risk-neutral in the robust setting, whereas generating firms clearly behave more risk-averse.

Goals and measures for analyzing power consumption data in manufacturing enterprises
Authors: Henning Sören , Hasselbring Wilhelm , Burmester Heinz , Möbius Armin , Wojcieszak Maik 
Published: March 2021

AbstractThe Internet of Things adoption in the manufacturing industry allows enterprises to monitor their electrical power consumption in real time and at machine level. In this paper, we follow up on such emerging opportunities for data acquisition and show that analyzing power consumption in manufacturing enterprises can serve a variety of purposes. In two industrial pilot cases, we discuss how analyzing power consumption data can serve the goals reporting, optimization, fault detection, and predictive maintenance. Accompanied by a literature review, we propose to implement the measures real-time data processing, multi-level monitoring, temporal aggregation, correlation, anomaly detection, forecasting, visualization, and alerting in software to tackle these goals. In a pilot implementation of a power consumption analytics platform, we show how our proposed measures can be implemented with a microservice-based architecture, stream processing techniques, and the fog computing paradigm. We provide the implementations as open source as well as a public show case allowing to reproduce and extend our research.
Structured climate financing: valuation of CDO on inhomogeneous asset pools
Authors: Packham N. 
Published: March 2021

AbstractRecently, a number of structured funds have emerged as public-private partnerships with the intent of promoting investment in renewable energy in emerging markets. These funds seek to attract institutional investors by tranching the asset pool and issuing senior notes with a high credit quality. Financing of renewable energy (RE) projects is achieved via two channels: small RE projects are financed indirectly through local banks that draw loans from the fund’s assets, whereas large RE projects are directly financed from the fund. In a bottom-up Gaussian copula framework, we examine the diversification properties and RE exposure of the senior tranche. To this end, we introduce the LH++ model, which combines a homogeneous infinitely granular loan portfolio with a finite number of large loans. Using expected tranche percentage notional (which takes a similar role as the default probability of a loan), tranche prices and tranche sensitivities in RE loans, we analyse the risk profile of the senior tranche. We show how the mix of indirect and direct RE investments in the asset pool affects the sensitivity of the senior tranche to RE investments and how to balance a desired sensitivity with a target credit quality and target tranche size.
Four-quark matter—a new era of spectroscopy
Authors: Liu Zhiqing 
Published: March 2021

AbstractIn 1964, both Gell-Mann and Zweig proposed the famous Quark Model in particle physics, which tells us hadrons are built of three quarks (baryons) or quark anti-quark pair (mesons). However, the theory of strong interaction—QCD—allows the existing of hadrons beyond the conventional baryon and meson picture. These new hadron states are called exotic hadrons, and have been searched for over the past half century. In this review, I will introduce you the discovery of a new particle called Zc(3900), which is considered as the first convincing four-quark particle. The observation of four-quark matter gains great interest in particle physics, and triggered subsequent intensive study of exotic hadrons, which brings us to a new era of hadron spectroscopy and refreshes our knowledge about the hadronic matter in our universe.

AbstractObjectives:Coronavirus disease (COVID-19) has been identified as an acute respiratory illness leading to severe acute respiratory distress syndrome. As the disease spread, demands on health care systems increased, specifically the need to expand hospital capacity. Alternative care hospitals (ACHs) have been used to mitigate these issues; however, establishing an ACH has many challenges. The goal of this session was to perform systems testing, using a simulation-based evaluation to identify areas in need of improvement.Methods:Four simulation cases were designed to depict common and high acuity situations encountered in the ACH, using a high technology simulator and standardized patient. A multidisciplinary observer group was given debriefing forms listing the objectives, critical actions, and specific areas to focus their attention. These forms were compiled for data collection.Results:Logistical, operational, and patient safety issues were identified during the simulation and compiled into a simulation event report. Proposed solutions and protocol changes were made in response to the identified issues.Conclusion:Simulation was successfully used for systems testing, supporting efforts to maximize patient care and provider safety in a rapidly developed ACH. The simulation event report identified operational deficiencies and safety concerns directly resulting in equipment modifications and protocol changes.

AbstractObjective:In this work, in order to establish a better comprehension of the association between Argentina and its neighbor countries’ capacity, and COVID-19 burden during the first 3 months, different indicators were evaluated.Method:We analyzed the association between GHSI, INFORM index and COVID-19 burden (number of confirmed cases and deaths), also the number of tests, lethality and the stringency of Governmental policies were evaluated.Results:Uruguay, Paraguay, and Bolivia started earlier different prevention measures. The number of tests differs, as Chile is the 1 that makes more. Uruguay and Paraguay register fewer positive cases and deaths from COVID-19. The GHS index is led by Brazil, followed by Argentina, and then Chile. However, the INFORM index is led by Uruguay followed by Argentina, while Chile and Paraguay are on par.Conclusion:The countries that took preventive measures earlier and carried out a more tests are the ones that are obtaining the best results against COVID-19.
