Storage Assignment Using Nested Metropolis Sampling and Approximations of Order Batching Travel Costs
Authors: Oxenstierna Johan , Malec Jacek , Krueger Volker 
Published: April 2024

AbstractThe Storage Location Assignment Problem (SLAP) is of central importance in warehouse operations. An important research challenge lies in generalizing the SLAP such that it is not tied to certain order-picking methodologies, constraints, or warehouse layouts. We propose the OBP-based SLAP, where the quality of a location assignment is obtained by optimizing an Order Batching Problem (OBP). For the optimization of the OBP-based SLAP, we propose a nested Metropolis algorithm. The algorithm includes an OBP-optimizer to obtain the cost of an assignment, as well as a filter which approximates OBP costs using a model based on the Quadratic Assignment Problem (QAP). In experiments, we tune two key parameters in the QAP model, and test whether its predictive quality warrants its use within the SLAP optimizer. Results show that the QAP model’s per-sample accuracy is only marginally better than a random baseline, but that it delivers predictions much faster than the OBP optimizer, implying that it can be used as an effective filter. We then run the SLAP optimizer with and without using the QAP model on industrial data. We observe a cost improvement of around 23% over 1 h with the QAP model, and 17% without it. We share results for public instances on the TSPLIB format.
Towards Data- and Compute-Efficient Fake-News Detection: An Approach Combining Active Learning and Pre-Trained Language Models

Published: April 2024

AbstractIn today’s digital era, dominated by social media platforms such asTwitter,Facebook, andInstagram, the swift dissemination of misinformation represents a significant concern, impacting public sentiment and influencing pivotal global events. Promptly detecting such deceptive content with the help of Machine Learning models is crucial, yet it comes with the challenge of dealing with labelled examples for training these models. Impressive performance results were recently achieved by high-capacity pre-trained transformer-based models (e.g., BERT). Still, such models are too data- and compute-demanding for many critical application contexts where memory, time, and energy consumption must be limited. Here, we propose an innovative semi-supervised method for efficient and effective fake news detection using a content-oriented classifier based on a small-sized BERT embedder. After fine-tuning this model on the sole few labelled data available, an iterative Active Learning (AL) process is carried out, which benefits from limited experts’ feedback to acquire more labelled data for improving the model. The proposed method ensures good detection performances using a few training samples, reasonably small human intervention, and compute/memory costs.
Absence of Metformin in Fetal Circulation Following Maternal Administration in Late Gestation Pregnant Sheep
Authors: Rozance Paul J. , Brown Laura D. , Wesolowski Stephanie R. 
Published: April 2024

AbstractIn human pregnancy, metformin administered to the mother crosses the placenta resulting in metformin exposure to the fetus. However, the effects of metformin exposure on the fetus are poorly understood and difficult to study in humans. Pregnant sheep are a powerful large animal model for studying fetal physiology. The objective of this study was to determine if maternally administered metformin at human dose-equivalent concentrations crosses the ovine placenta and equilibrates in the fetal circulation. To test this, metformin was administered to the pregnant ewe via continuous intravenous infusion or supplementation in the drinking water. Both administration routes increased maternal metformin concentrations to human dose-equivalent concentrations of ~ 10 µM, yet metformin was negligible in the fetus even after 3–4 days of maternal administration. In cotyledon and caruncle tissue, expression levels of the major metformin uptake transporter organic cation transporter 1 (OCT1) were < 1% of expression levels in the fetal liver, a tissue with abundant expression. Expression of other putative uptake transporters OCT2 and OCT3, and efflux transporters multidrug and toxin extrusion (MATE)1 and MATE2were more abundant. These results demonstrate that the ovine placenta is impermeable to maternal metformin administration. This is likely due to anatomical differences and increased interhaemal distance between the maternal and umbilical circulations in the ovine versus human placenta limiting placental metformin transport.
Youth Work, Youth Studies, and Co-design: Sustaining a Dynamic Nexus to Progress Youth Participation
Authors: Lohmeyer Ben Arnold , McGregor Joel Robert , Wood Bronwyn Elizabeth 
Published: April 2024

AbstractYouth work practitioners and youth researchers both share a keen interest in the lives, experiences, and well-being of young people; however, the skills and expertise held by practitioners and researchers have not always been mutually valued leading to tensions and a research-practice gap. The rise of co-design methods that prioritise relational skills and ethics appears to mark a moment for closing or reducing this gap. Rather than accepting this convergence at face value, in this paper, we examine some of the key tensions around (1) relational ethics and decision-making, (2) holding multiple roles and expertise, and (3) structures that constrain or sustain participation to argue for sustaining a dynamic research-practice nexus. Drawing on our experience and practitioner-researchers, we argue that rather than simply overlooking the practical and ethical tensions between practice and research, sustaining a dynamic nexus comprising of continuing dialogue and collaboration can foster and progress co-design methods in pursuit of the aims of youth participation.
The contribution of qualitative methods to economic research in an era of polycrisis
Authors: Porak Laura , Reinke Rouven 
Published: April 2024

AbstractThis article argues that the considerable socio-economic and political challenges posed by the polycrisis can be better understood through the application of qualitative methods in economic research as quantitative methods fall short in this context. We argue that the integration of qualitative methods into economic research is crucial for two main reasons: first, from a philosophical point of view, a more comprehensive perspective on economic phenomena increases the epistemic quality of economic knowledge, and second, for political reasons, more pluralism in economics increases the democratic quality of capitalistic societies. We provide a review of the literature of the use of qualitative methods in economics and its philosophical underpinnings. Using specific examples of the application of qualitative methods in economic policy research, we show how valuable such perspectives are in facilitating a deeper understanding of the polycrisis. We address concerns against qualitative research in the economic discipline and how our analysis serves to mitigate some of these concerns in the context of the polycrisis. We conclude with a discussion on the potential role of qualitative methods in economic research.
Performance of GFRP-RC precast cap beam to column connections with epoxy-anchored reinforcement: a numerical study

Published: April 2024

AbstractIn this study, a detailed finite element investigation was conducted to evaluate the performance of glass fibre-reinforced polymer (GFRP) RC precast cap beam to column connections connected with epoxy-anchored reinforcement (epoxy duct connection). The developed model was initially validated against three experimental results with different anchored GFRP reinforcement considering the effect of reinforcement slippage. Different interaction models for slippage simulation were evaluated and discussed. The validated model was then utilized to investigate the effect of anchored length, bar diameters, anchored reinforcement amount, and the geometry of the connection. The results indicate that an optimum anchored length, equal to 25 times the bar's diameter, should be provided. It was also found that the precast beam-to-column element connection should be designed for a moment capacity at least 25% higher than that of the column section. Moreover, a minimum beam width, depth and beam overhanging length of 1.75, 1.6 and 0.25 times the column width respectively were recommended to be considered in design. The results from this study can provide direct guidelines for the design of precast GFRP-RC cap beam to the column connection with epoxy anchored reinforcement, especially in applications where precast elements need to be erected quickly, a novel method that can accelerate the construction of jetties and bridges.

AbstractHistorically, research disciplines have successfully operated independently. However, the emergence of transdisciplinary research has led to convergence methodologies, resulting in groundbreaking discoveries. Despite the benefits, graduate programs face challenges in implementing transdisciplinary research and preparing students for real-world collaboration across diverse disciplines and experience levels. We propose a convergence training framework integrating project-based learning, training modules, and collaborative teaming to address this. This approach, tested in a multi-institutional workshop, proved effective in bridging expertise gaps and fostering successful convergence learning experiences in computational biointerface (material–biology interface) research. Here, biointerface research focuses on control of biomolecular interactions with technologically relevant material surfaces, which is a critical component of biotechnology and engineering applications. Positive outcomes, including conference presentations and published models, endorse the framework's application in graduate curricula, particularly for students engaging in transdisciplinary collaboration.
Some Challenges for Moreau's Theory of Wrongful Discrimination
Authors: Gilabert Pablo 
Published: April 2024

AbstractAt the heart of Sophia Moreau's theory of wrongful discrimination is the moral duty to treat others as equals. This article raises some challenges regarding the contours of this duty and suggests some ways to make the theory stronger. In particular, it suggests that we incorporate a cosmopolitan view of the duty's scope, that we illuminate the features at the basis of individuals’ equal moral status to determine its grounds, and that we identify some considerations about important interests to articulate its contents. The relation between Moreau's theory and human rights discourse is also briefly examined, and more engagement with the latter is recommended.
Pluralist Theories of Wrongful Discrimination
Authors: Smith Dale 
Published: April 2024

AbstractIn Faces of Inequality, Sophia Moreau offers a pluralist theory of discrimination, according to which discriminatory conduct involves one or more of (at least) three types of wrong. She claims, further, that each of these wrongs represents a failure to treat some people as the equal of others. I argue that this further claim is mistaken. I also suggest that there may be no need for a pluralist theory of discrimination to identify a property that is shared by the different types of wrong recognised by the theory (beyond the fact that each is present in cases of wrongful discrimination).
Discrimination, Pluralism, and Social Subordination: On Moreau's Faces of Inequality
Authors: Sangiovanni Andrea 
Published: April 2024

AbstractSophia Moreau's wide-ranging and nuanced book defends a pluralist view of wrongful discrimination. I argue three points. First, I argue that Moreau's account of deliberative freedom does not provide a distinct ground for objecting to discrimination. Second, I argue that there is not as wide a gap between her view and expressivism as she makes there out to be. Third, there is an intriguing gap in the argument that deserves further exploration: Moreau never provides us with an account of when and why social subordination is wrong.

The survival of three large agricultural estates on the north Hampshire-south Berkshire border during the interwar period
Authors: Jones Gareth , Burchardt Jeremy , Tranter Richard 
Published: April 2024

AbstractHistorians credit the interwar period with the demise of the great agricultural estates but many survived, reduced in area and refocussed on new priorities. Three estates lying in close proximity in north Hampshire and south Berkshire had very divergent interests, but there were similarities, and significant differences, in the manner in which they survived the interwar period. One invested in a programme of renewal of houses and farm buildings, and another adopted a more commercial approach to managing its diverse interests and the third retrenched, cutting investment but maintaining the status quo as an agricultural and shooting estate. All three survived, relatively intact and financially stable, and remain in operation today. An examination of estate financial performance before and after the Great War provides the context to the strategies pursued by the owners and their Land Agents, and their place in the broader rural landscape of the 1920s and 1930s.

Published: April 2024

Abstract
The Institute and Faculty of Actuaries UK Asbestos Working Party update 2020 sets out the methodology and assumptions used to estimate the potential cost of asbestos-related claims to the UK Employers’ Liability Insurance Market. The Working Party has estimated the UK EL Insurance Market cost for the following asbestos-related disease types: mesothelioma, lung cancer, asbestosis and pleural thickening, and pleural plaques. For each disease type the Working Party has constructed a range of scenarios to highlight the uncertainty of these estimates. The Working Party reminds practitioners that use the Working Party scenarios that they should always consider the experience and trends that have occurred since the scenarios were published, adjusting the scenarios to take into account new information.
Recovering Differential Forces From the GRACE‐D Accelerometer

Published: April 2024

AbstractThe reduction of non‐gravitational accelerations through an onboard accelerometer is a vital part of accurately estimating gravity fields for Gravity Recovery and Climate Experiment (GRACE) Follow‐On (GRACE‐FO). Current accelerometer quality, specifically a defect on the GRACE‐D accelerometer, necessitates the use of extensive calibration techniques to optimally utilize the accelerometer measurements. This paper describes these techniques and correction algorithms as they are used for the official GRACE‐FO accelerometer products, which rest on the information present in the partially functional GRACE‐D accelerometer. First, transplanted data from GRACE‐C is used to remove common effects between the spacecraft. Then, GRACE‐D data is utilized to compute a correction to the transplanted data to account for solar radiation pressure (SRP) and albedo using a parity argument and to account for non‐common drag and thruster leaks in the attitude control system. The SRP and albedo term predominantly improves C3,0 while the drag and leaky thruster term improves the gravity field across the entire spectrum. Finally, some comments on alternative data usage, initial modifications to the algorithms to account for other spacecraft operational modes, and future outlook are provided.

AbstractSedimentary carbonates are known to be carried into the deep mantle by subducted slabs, and studies on mantle‐derived magmas have attempted to trace the recycled carbonate in their mantle source. However, the final depth of storage of recycled carbonate and the role of recycled carbonate in the partial melting of mantle remain controversial. Peralkaline‐carbonatite suites are considered to have been derived from a carbonated mantle source and are windows to evaluate carbon in the mantle. In this study, we report the Zn isotopic compositions of a peralkaline‐carbonatite suite from the Tarim Large Igneous Province (Tarim LIP). The peralkaline‐carbonatite suite has heavier δ66Zn than normal mantle with δ66Zn of 0.34–0.40 ‰ for nephelinite, 0.35–0.47 ‰ for aillikite, 0.51–0.55 ‰ for nepheline syenite, 0.58–0.67 ‰ for calciocarbonatite and 0.38–0.56 ‰ for magnesiocarbonatite. The heavy Zn isotopic compositions of the peralkaline‐carbonatite suite in the Wajilitag complex suggest the incorporation of recycled carbonate‐bearing materials into the deep mantle. We infer that the calciocarbonatite was produced by the initial partial melting of subducted MgSiO3/MgO + C‐bearing carbonated eclogite, whereas the magnesiocarbonatite, aillikite, and nephelinite are considered as reacted melts between carbonated eclogite‐derived melts and peridotite. The heavy Zn isotopic compositions of the nepheline syenite are attributed to fractional crystallization from nephelinite magma in the magma reservoir. Our study highlights the incorporation of carbonated eclogite as an important agent of recycled carbon in the deep mantle and interactions between carbonated eclogite‐derived melts and peridotite lead to the complex lithological heterogeneities in the peralkaline‐carbonatite suite in Tarim LIP.

AbstractUsing the high‐time‐resolution data from the Magnetospheric Multiscale mission, precursor waves upstream of foreshock transient (FT) shocks are statistically investigated using the four‐spacecraft timing method. The wave frequencies and wave vectors determined in the plasma rest frame (PRF) are shown to follow the cold plasma dispersion relation for whistler waves. Combining with the feature of the right‐hand polarization in the PRF, the precursors are identified as whistler‐mode waves around the lower hybrid frequency. The occurrence of whistler precursors is independent of the Alfvén Mach number and the FT shock normal angle. More importantly, all the whistler precursors have group velocities pointing upstream in the shock frame, suggesting the dispersive radiation to be a possible generation mechanism. The study improves the understanding of not only the whistler precursors but also the overall FT shock dynamics.
Future Slower Reduction of Anthropogenic Aerosols Enhances Extratropical Ocean Surface Warming Trends
Authors: Gu Pingting , Gan Bolan , Cai Wenju , Wang Hai , Wu Lixin 
Published: April 2024

AbstractGlobal surface temperature short‐term trends fluctuate between cooling and fast‐warming under the combined action of external forcing and internal variability, significantly influencing the detectability of near‐term climate change. A key driver of these variations is anthropogenic aerosols (AAs), which have undergone a non‐monotonic evolution with rapid reduction in recent decades. However, their reduction is projected to decelerate under a high carbon emission scenario, yet the impact on surface temperature trends remains unknown. Here, using initial‐perturbation large ensembles, we find that future slowdown in AA reduction over Europe and North America expedites the subpolar North Atlantic surface warming by intensifying the Atlantic meridional overturning circulation. Further, it accelerates the South Indian Ocean and Southern Ocean surface warming through positive low‐cloud feedback and oceanic dynamical adjustment, triggered by the poleward migration of westerlies under interhemispheric energy constraint. These AA‐driven warmings exacerbate greenhouse warming, significantly enhancing the detectability of local decadal warming trends.

AbstractThe proton radiation belt contains high fluxes of adiabatically trapped protons varying in energy from ∼one to hundreds of megaelectron volts (MeV). At large radial distances, magnetospheric field lines become stretched on the nightside of Earth and exhibit a small radius of curvature RC near the equator. This leads protons to undergo field line curvature (FLC) scattering, whereby changes to the first adiabatic invariant accumulate as field strength becomes nonuniform across a gyroorbit. The outer boundary of the proton belt at a given energy corresponds to the range of magnetic L shell over which this transition to nonadiabatic motion takes place, and is sensitive to the occurrence of geomagnetic storms. In this work, we first find expressions for nightside equatorial RC and field strength Be as functions of Dst and L* to fit the TS04 field model. We then apply the Tu et al. (2014, https://doi.org/10.1002/2014ja019864) condition for nonadiabatic onset to solve the outer boundary L*, and refine our expression for RC to achieve agreement with Van Allen Probes observations of 1–50 MeV proton flux over the 2014–2018 era. Finally, we implement this nonadiabatic onset condition into the British Antarctic Survey proton belt model (BAS‐PRO) to solve the temporal evolution of proton fluxes at L ≤ 4. Compared with observations, BAS‐PRO reproduces storm losses due to FLC scattering, but there is a discrepancy in mid‐2017 that suggests a ∼5 MeV proton source not accounted for. Our work sheds light on outer zone proton belt variability at 1–10 MeV and demonstrates a useful tool for real‐time forecasting.
