Paradigm shift in mechanical system design: toward automated and collaborative design with digital twin web
Authors: Ala-Laurinaho Riku , Autiosalo Juuso , Laine Sampo , Hakonen Urho , Viitala Raine
Published: October 2024

Analyzing multi-vendor mechanical system designs requires a significant amount of manual work, resulting in a design paradigm where analysis is conducted only after the design is locked and components are selected. This leads to a suboptimal design with compatibility issues, over-dimensioned components, inferior performance, poor energy efficiency, and a lack of collaboration between OEMs (original equipment manufacturers) and system integrators. To overcome these issues, this paper proposes Co-Des (collaborative design) framework for automated and collaborative multi-vendor system design. The framework relies on standardized digital twin documents (DTD) of system designs, components, and analyses. The discoverability and distribution of these DTDs are enabled with digital twin web (DTW). Co-Des framework allows for finding suitable components for the design task by automatically running selected analyses employing component digital twins. In addition, OEMs can provide customized components for system integrators using the initial system design defined in the system design DTD. The use of the Co-Des framework was demonstrated with a windmill powertrain design use case, and the applicability of the automated assembly analysis for component selection was verified with performance measurements. The adoption of the proposed framework will lead to a paradigm shift from manual and siloed work relying on the exchange of PDFs to a more automated and collaborative design of mechanical systems. The adoption rate is defined by the willingness of system integrators to publish their initial system designs and OEMs their components as public digital twins.

Published: October 2024

Synthetic populations are representations of actual individuals living in a specific area. They play an increasingly important role in studying and modeling individuals and are often used to build agent-based social simulations. Traditional approaches for synthesizing populations use a detailed sample of the population (which may not be available) or combine data into a single joint distribution, and draw individuals or households from these. The latter group of existing sample-free methods fail to integrate (1) the best available data on spatial granular distributions, (2) multi-variable joint distributions, and (3) household level distributions. In this paper, we propose a sample-free approach where synthetic individuals and households directly represent the estimated joint distribution to which attributes are iteratively added, conditioned on previous attributes such that the relative frequencies within each joint group of attributes are maintained and fit granular spatial marginal distributions. In this paper we present our method and test it for the Zuid-West district of The Hague, the Netherlands, showing that spatial, multi-variable and household distributions are accurately reflected in the resulting synthetic population.
Seismic behaviour and design of a tall mixed reinforced concrete–steel structure supporting an oil refinery reactor
Authors: Radaiou Smaragdi , Skalomenos Konstantinos , Papagiannopoulos George
Published: October 2024

This study investigates the seismic behaviour of a special mixed reinforced concrete-steel structure that supports an oil refinery reactor. The structure is 64.90 m tall and consists of three parts: (a) a reinforced concrete frame basement; (b) a steel braced frame that supports the oil reactor and (c) the steel reactor itself. A three-dimensional model of the structure is created to perform static non-linear (pushover) analyses in order to obtain the capacity curves and understand the overall inelastic behavior of the structure. The results of the pushover analyses reveal that the structure exhibits similar inelastic behavior in both horizontal directions and satisfies the capacity design principles. The structure exhibits limited ductility considering the fact that has been designed with a behavior factor of q = 1.5 and primary damages are expected mainly in concrete members. Subsequently, dynamic non-linear time-history (NLTH) analyses are performed utilizing the three translational components of three seismic motions recorded during past earthquakes. These results involve: (i) the maximum values for displacements, accelerations and base shears; (ii) the maximum stresses at critical points of the oil refining reactor and (iii) the formation of plastic hinges at columns, beams and braces of the structure. Contrary to pushover analyses, NLTH analyses revealed the development of plastic hinges, hence seismic damage, that do not follow the desirable formation pattern. Moreover, the accelerations and displacements observed are expected to cause failure of the piping and mechanical equipment, while local failure of the high-stress areas of the shell of the reactor may be possible. Localized strengthening might be necessary to avoid repair works and downtime after such seismic event.
Policy Learning for Many Outcomes of Interest: Combining Optimal Policy Trees with Multi-objective Bayesian Optimisation
Authors: Rehill Patrick , Biddle Nicholas
Published: October 2024

Methods for learning optimal policies use causal machine learning models to create human-interpretable rules for making choices around the allocation of different policy interventions. However, in realistic policy-making contexts, decision-makers often care about trade-offs between outcomes, not just single-mindedly maximising utility for one outcome. This paper proposes an approach termed Multi-Objective Policy Learning (MOPoL) which combines optimal decision trees for policy learning with a multi-objective Bayesian optimisation approach to explore the trade-off between multiple outcomes. It does this by building a Pareto frontier of non-dominated models for different hyperparameter settings which govern outcome weighting. The method is applied to a real-world case-study of pricing targetting subsididies for anti-malarial medication in Kenya.

Published: October 2024

This study aimed to examine the impact of a pilgrimage on the Way of St. James on psychological distress and subjective well-being, and to compare these outcomes with a control group on non-pilgrimage vacations. Additionally, the study explored psychological process variables that may mediate the pilgrimage's beneficial effects. A nonrandomized pretest-posttest design was used, involving 444 pilgrims and 124 controls. Participants completed baseline and post-experience self-reported measures of psychological distress, subjective well-being, and psychological processes (i.e., mindfulness, nonattachment, engaged living). A 3-month follow-up was conducted only in the pilgrim group. Mediation analyses examined psychological processes as potential mediators of pre-post change in the pilgrim group (vs. control). Within-group analyses revealed that the pilgrim group experienced improvements in psychological distress, subjective well-being, and psychological processes immediately post-experience, with most measures sustaining improvement at the 3-month follow-up. Compared to the control group, pilgrims showed significantly greater increases in positive affect, life satisfaction, and valued living, alongside greater reductions in anxiety, depression, and perceived stress. Valued living partially mediated the relationship between pilgrimage and positive affect, and fully mediated the effects on perceived stress, negative affect, life satisfaction, and subjective happiness. Pilgrimage on the Way of St. James effectively reduced psychological distress and enhanced subjective well-being, with greater benefits observed compared to a non-pilgrimage vacation control group. Consistent with the concept of pilgrimage as a transformative experience, significant improvements in valued living were noted, which mediated some of the positive outcomes post-pilgrimage. The Way of St. James may serve as a valuable complementary approach for alleviating distress and promoting well-being. Further studies exploring the effects of this pilgrimage on specific populations and using more robust study designs are warranted.

Assessment of isoconversional methods and peak functions for the kinetic analysis of thermogravimetric data and its application to degradation processes of organic phase change materials
Authors: Bayón Rocío , García-Rojas Redlich , Rojas Esther , Rodríguez-García Margarita M.
Published: October 2024

In this work, theoretical kinetic curves of both single- and multi-step reaction mechanisms were simulated by using different sets of kinetic parameters. Various isoconversional methods were applied for the kinetic analysis of these curves so that the corresponding activation energy vs. conversion degree curves were obtained and then compared with the energy values used in the simulations. For single-step reaction mechanisms Friedman method resulted to be the most accurate while for multi-step reaction mechanisms, Kissinger–Akahira–Sunose and Coats–Redfern methods led to the most accurate estimation of the activation energy. On the other hand, conversion rate curves of different single-step reaction mechanisms were fitted with two kinds of peak functions (normalized Fraser–Suzuki and generalized logistic) so that the relationships between the parameters of these functions and the kinetic parameters used in the simulations were obtained. These relationships were then used in the mathematical deconvolution analysis of conversion rate curves simulated for multi-step reaction mechanisms. In general, the curves resulting from deconvolution fitted quite well the simulated conversion rate curves and the analysis of the resulting single-step reaction curves with Kissinger method led the kinetic parameters close to the ones used in the simulations. Finally, a similar kinetic analysis was applied to experimental thermogravimetric measurements taken both under N2 and air for two phase change materials (PCMs) based on polyethylene glycol, PEG6000 and PEG12000. Activation energy values obtained with isoconversional methods for the measurements under N2, varied from 40 kJ mol−1 at low conversions up to 150 kJ mol−1 at high conversions, whereas for the measurements under air the energy values remained almost constant in the range of 50–75 kJ mol−1. The lower activation energies obtained for the measurements under air are clearly associated with the polymer combustion. The experimental conversion rate curves were deconvoluted with the most appropriate peak functions so that the possible single-step reaction mechanisms occurring in these PCMs were separated and further analyzed with Kissinger method. The activation energies obtained with this method were in good agreement with the values resulting from the isoconversional methods.

Published: October 2024

Five types of glass microspheres with alumina and 40–80 mol.% Y3Al5O12 were prepared using solgel Pechini and flame synthesis techniques. Glass thermal behavior was analyzed using DSC/TG, XRD and SEM, and the JMAK model was applied to study crystallization kinetics and determine prevailing mechanisms. All samples, except the one with 80 mol.% YAG, had two exothermic effects in their DSC curves. The first appeared between 937 and 950 °C, while the second was observed between 958 and 1102 °C. XRD analysis of crystallized microspheres confirmed the presence of YAG and various forms of alumina phases in the samples with lower YAG/higher Al2O3 content (40 and 50 mol.%). The sample with the highest YAG content showed the strongest tendency to crystallize in the kinetics study. The value of apparent activation energy (Eapp) of this sample was 987.3 ± 13.0 kJ mol−1. For the remaining samples, the values of Eapp were higher and ranged from 1215.1 ± 10.6 to 1847.5 ± 9.3 kJ mol−1, indicating the lowest ability of these compositions to crystallization. The growth of three-dimensional (3-D) YAG crystals was predominant in glasses with the highest (80 mol.%) YAG content. One-dimensional (1-D) growth of γ-Al2O3 crystals and 3-D growth of YAG crystals was predominant in glasses with the lowest (40 mol.%) YAG content.

Metal enrichment in aquatic ecosystems has compromised the potential of fish to enhance food security. The uMgeni River drains urban and industrialized catchment and flows through economically disadvantaged rural communities that opt for fish to supplement their protein needs. However, there are uncertainties on the safety of consuming fish from the uMgeni River. The present study aims to explore metal distribution between the water, sediment, and tissues of the preferred Oreochromis mossambicus, and evaluate whether concentrations in the muscle are safe for human consumption. The water, sediment, and fish samples were collected from Inanda and Nagle dams, and metal concentrations were analysed using inductively coupled plasma mass spectrometry. Alkaline pH was observed at both dams and metals were below detectable level in the water column. Even though metal concentrations in the water column were below detectable levels, significant concentrations were found in the sediment. No consistent trend in metal concentrations was observed across tissues, but higher levels were generally found in the liver, followed by the gill, and then the muscle. Nickel (Ni) and lead (Pb) exhibited concentrations exceeding the permissible limit for human consumption. Similarly, the target hazard quotient exceeded the threshold of 1 for Pb, chromium (Cr), and antimony (Sb) at both dams with Inanda Dam showing higher indices for Sb and Pb. The carcinogenic risk for the three metals was also found to be higher than 10–6. These findings suggest that consumption of O. mossambicus from the uMgeni River should be limited to no more than 150 g per week.
Research on the quality evaluation of crude drugs
Authors: Fuchino Hiroyuki
Published: October 2024

As crude drugs are natural products, their quality may vary. However, the degradation of the active ingredients in the compositional changes that occur during processing and preparation also affects the medicinal properties of the Kampo formula, which uses herbal medicines; therefore, a detailed investigation of the effects of compositional changes during preparation is required. Plant constituents vary in content depending on the year of cultivation and the plant part; however, detailed studies have rarely been reported for some crude drugs. Liquid chromatography-nuclear magnetic resonance/mass spectrometry revealed the degradation process of saponins, which are unstable components of the crude drug “Achyranthes root.” The presence of diterpenes unstable with respect to drying temperature in the leaves of the crude drug “Leonurus herb” was revealed and their structures were elucidated. At the examination stage of the degradation process of perillaldehyde, the characteristic aromatic component of Perilla herb, it was elucidated that some specimens contained a small amount of perillaldehyde and that they contained more α-asarone. A trend toward lower ephedrine content was observed toward the tip of the above-ground branching of the Ephedra herb. Multivariate analysis was also introduced into the quality assessment of crude drugs and was established as a tool to identify bioactive compounds using the component diversity of crude drugs and to elucidate component differences due to the cultivation environment.

Maximal extractable value: Current understanding, categorization, and open research questions
Authors: Gramlich Vincent , Jelito Dennis , Sedlmeir Johannes
Published: October 2024

In traditional financial markets, front-running is a well-structured phenomenon. It represents a form of privileged actors utilizing knowledge or power advantages to extract undue profit at the cost of other stakeholders. Various mitigation strategies have emerged, ranging from market design to regulatory measures. More recently, a similar and substantially richer variety of means to gain unethical profit from power asymmetries has appeared in the context of blockchain-based decentralized applications. This phenomenon is called “maximal extractable value” (MEV). Despite the decentralized nature and inherent transparency of blockchain ledgers, MEV is particularly prevalent and challenging to mitigate. While related work in computer science and algorithmic game theory has already identified several different ways in which MEV manifests in decentralized finance (DeFi) and outlined partial solution approaches, a discussion of its impacts in the information systems (IS) domain is still absent. A holistic definition of MEV and how it can be exploited is necessary for the discussion of its potential implications for blockchain-based IS for businesses and public institutions. This paper conducts a systematic literature review to close this gap. It consolidates the diverging definitions of MEV and provides a categorization of the different ways in which it can manifest. As such, we synthesize and review the existing state of knowledge on MEV and point to undiscovered areas relevant to decentralized electronic markets in the form of a research agenda.
Model-based assembly process planning for flexible aircraft cabin architectures
Authors: Ghanjaoui Yassine , Satwan Philip , Biedermann Jörn , Nagel Björn
Published: October 2024

The configuration and equipment of an aircraft cabin has a significant impact on the passenger’s flight experience. To meet the needs of passengers and improve the flight experience, airlines repeatedly demand customised adaptations to the cabin design. The implementation of these changes requires a high degree of flexibility in production and can lead to difficulties in setting up a fixed final assembly line. In addition, unforeseen events and changes in the OEMs’ supply chain require a rapid response in aircraft production to be able to deliver on time. Digitalisation in product development and production planning makes it possible to overcome these challenges and makes an important contribution to flexibility, time and cost efficiency. This paper presents a digital approach to modelling and flexible planning of assembly processes of the cabin. To this end, aircraft design data is automatically linked to the assembly system to react quickly to design changes in the assembly planning process. The integration is realised in a system architecture model depicted with the systems modelling language (SysML). The architecture model follows the formal process description defined in VDI3682. A planning algorithm then uses the production architecture parameters to optimise the assembly processes, e.g. in terms of time. The approach presented is demonstrated using the example of scheduling the pre-assembly processes of the "crown module". The latter includes all structural and functional components above the window panels, such as overhead bins, electrics and air conditioning. The results show how changes in aircraft and cabin design or in the production plant and resources can be flexibly evaluated. This allows conceptual changes to be evaluated and traded before the cabin design is frozen and transferred to real production. These advantages contribute to the time and cost optimisation of aircraft production. This work thus makes a valuable contribution to the further development of digital solutions in aircraft production.
Hazard Risk Management as a Principal-Agent Problem: A Comparison of Principal- and Agent-Salient Risk Indicators
Authors: Frimpong Eugene , Howard Gregory , Kruse Jamie
Published: October 2024

We consider the goal of flood risk managers to induce voluntary flood risk mitigation actions from homeowners in at-risk areas by first distinguishing between risk metrics that are salient to policy makers and risk managers (denoted principal-salient) and risk metrics that are salient to homeowners (denoted agent-salient). We derive a single index each for principal- and agent-salient risk, then combine these indices with data on households’ preference for parcel-level flood risk mitigation activities. We estimate choice models to understand how risk indicator type affects homeowner preferences and policy recommendations. Models with agent-salient risk metrics outperform those utilizing principal-salient risk metrics. More importantly, willingness to accept estimates show the two risk measures yield significantly different policy outcomes, with greater agent-salient risk being associated with greater willingness to adopt risk mitigation but no similar relationship existing between principal-salient risk and willingness to adopt risk mitigation. We note that there are important benefits from using both types of metrics when targeting risk mitigation grants.
The Effect of Reward Magnitude on Different Types of Exploration in Human Reinforcement Learning
Authors: Shimomura Kanji , Morita Kenji
Published: October 2024

How humans resolve the explore–exploit dilemma in complex environments is an important open question. Previous studies suggested that environmental richness may affect the degree of exploration in a type-specific manner and reduce random exploration while increasing uncertainty-based exploration. Our study examined this possibility by extending a recently developed two-armed bandit task that can dissociate the uncertainty and novelty of stimuli. To extract the pure effect of environmental richness, we manipulated the reward by its magnitude, not its probability, across blocks because reward probability affects outcome controllability. Participants (N = 198) demonstrated increased optimal choices when the relative reward magnitude was higher. A behavioral analysis with computational modeling revealed that a higher reward magnitude reduced the degree of random exploration but had little effect on the degree of uncertainty- and novelty-based exploration. These results suggest that humans modulate their degree of random exploration depending on the relative level of environmental richness. Combined with findings from previous studies, our findings indicate the possibility that outcome controllability also influences the exploration–exploitation balance in human reinforcement learning.

Penicillin allergy delabeling may benefit antimicrobial stewardship (AS). Cost of initial penicillin treatments following risk-stratified inpatient delabeling were compared to two hypothetical treatment regimens if delabeling had not occurred: (1) AS-guided and (2) Common Treatment. Penicillin allergy delabeling improved antimicrobial spectrum index, was cost-neutral, and averted unnecessary penicillin desensitizations.

The works under review must be located in this search for sustainable peace in Africa.
Striving for a Rapid Transition: How Companies are Approaching Integrating Respect for Human Rights in Their Climate Action
Authors: Areias Sophia Aspesi
Published: October 2024

Globally, companies are developing and implementing their strategies to reduce greenhouse gas emissions to limit the global temperature increase to 1.5 degrees Celsius above pre-industrial levels, in line with the Paris Agreement. However, there is also growing recognition and awareness of the potential negative impacts of these activities on human rights. Recent pressure from international normative standards and ESG expectations, emerging legislative developments, and legal precedents are driving companies to consider human rights impacts across their climate action. This piece explores some of the human rights risks associated with the transition to renewable energy; the transformation to regenerative agriculture; the scaling up of the circular economy; and the implementation of nature-based solutions. It then explores the challenges of conducting effective human rights due diligence given the scale and scope of the transitions needed and provides examples of how companies are seeking to respect human rights in their climate action.

The spatial Whitham equation
Authors: Carter John D. , Henderson Diane , Panayotaros Panayotis
Published: October 2024

The Whitham equation is a non-local, nonlinear partial differential equation that models the temporal evolution of spatial profiles of surface displacement of water waves. However, many laboratory and field measurements record time series at fixed spatial locations. To directly model data of this type, it is desirable to have equations that model the spatial evolution of time series. The spatial Whitham (sWhitham) equation, proposed as the spatial generalization of the Whitham equation, fills this need. In this paper, we study this equation and apply it to water-wave experiments on shallow and deep water. We compute periodic travelling-wave solutions to the sWhitham equation and examine their properties, including their stability. Results for small-amplitude solutions align with known results for the Whitham equation. This suggests that the systems are consistent in the weakly nonlinear regime. At larger amplitudes, there are some discrepancies. Notably, the sWhitham equation does not appear to admit cusped solutions of maximal wave height. In the second part, we compare predictions from the temporal and spatial Korteweg–de Vries and Whitham equations with measurements from laboratory experiments. We show that the sWhitham equation accurately models measurements of tsunami-like waves of depression, waves of elevation, and solitary waves on shallow water. Its predictions also compare favourably with experimental measurements of waves of depression and elevation on deep water. Accuracy is increased by adding a phenomenological damping term. Finally, we show that neither the sWhitham nor the temporal Whitham equation accurately models the evolution of wave packets on deep water.
Laboratory study of the effect of mean water current on the evolution of young wind waves
Authors: Kumar Krishanu , Shemer Lev
Published: October 2024

The spatial evolution of various statistical parameters of fetch-limited waves generated by steadily blowing wind over mean water flow in a wind-wave flume is investigated experimentally. Measurements are performed in both along- and against-wind current conditions, and compared with measurements in the absence of current. A rake of capacitance-type wave gauges is used to measure surface elevation for a wide range of wind and water current velocities; additionally, an optical wave gauge is used to measure the directional properties of the wind-wave field in the presence of a mean water current at multiple locations. The variation with fetch of essential wave parameters such as characteristic wave energy, dominant frequency, power spectra and temporal coherence, as well as higher-order statistical moments that characterize wave shape, is presented for co- and counter-wind water currents, and compared with the no-current condition. The findings in the presence of mean water flow are interpreted in the framework of the viscous shear flow instability model of Geva & Shemer (Phys. Rev. Lett., vol. 128, 2022, 124501).
Yield stress fluids solidifying in capillary imbibition
Authors: Kim Hanul , Choi Siyoung Q.
Published: October 2024

When subjected to external stress exceeding their yield stress (

$\sigma _{Y}$

), yield stress fluids (YSFs) undergo transition from solid to liquid. While the flow dynamics of capillary flows – including wetting, coating, spreading, and wicking – can be predicted accurately for fluids without yield stress, only a few asymptotic solutions have been validated against experiments for YSFs. In this study, we explore experimentally and theoretically the entire dynamics and solidifying process during capillary imbibition of YSFs, representing the fundamental aspect of capillarity-driven flow. We observe that during the gradual deceleration of capillary rise, YSFs exhibit apparent flow below

$\sigma _{Y}$

. This unexpected behaviour is linked to wall slip, manifested as plug flow in particle image velocimetry analyses. We introduce a model with numerical solutions, grounded in the rheological properties of YSFs and slip mechanisms, to accurately describe this liquid–solid transitional behaviour.
Projected loss of rock glacier habitat in the contiguous western United States with warming
Authors: Lute Abigail C. , Abatzoglou John T. , Fountain Andrew G. , Bartholomaus Timothy C.
Published: October 2024

Rock glaciers support alpine biodiversity and may respond more slowly to warming than snow or glaciers. While responses of snow and glaciers to climate change are relatively well understood, a robust assessment of rock glacier environmental niche, future distributions of rock glaciers and potential for development of rock glaciers from current glaciers is lacking. Using process-relevant, high-resolution environmental descriptors, we develop a species distribution model of the topographic, geologic and hydroclimatic niche of rock glaciers that provides novel estimates of potential rock glacier distributions for different climates. We identify mean annual air temperature and headwall area as the dominant controls on rock glacier spatial distributions, with rock glaciers more likely to be found in areas with mean annual temperatures close to −5°C, little rain, northern aspects and broad headwalls. While rock glacier climate equilibration may take hundreds of years, we find that equilibration to present climate will result in a 50% reduction in rock glacier habitat and equilibration to late 21st-century climate under a high-end warming scenario will result in a 99% reduction in rock glacier habitat across the western USA. Under future conditions, we find limited potential for glacier to rock glacier transformation (3% of glacierized area), concentrated in cold, high elevation, moderate precipitation areas.

‘Fat-cats’ versus ‘church mice’: unveiling legal aid practice from behind the shadows of private legal practice in England and Wales
Authors: Cooke Emma
Published: October 2024

This paper calls for the lawyering profession – which is often viewed as unabridged – to be reframed into two distinct occupations: legal aid practice and private practice, to better incorporate the divisions in labour. In order to better understand contemporary legal aid work and its workers, the hidden realities must be unveiled from behind their private counterparts, which opposingly signify wealth, professionalism, autonomy and privilege. Set within a context of crumbling professional identities, a shrinking industry and financial constraints, the paper draws on ethnographic and interview data. It finds that those working in legal aid undoubtedly face a more stagnated, under-resourced and precarious working environment, which means that their professional experience is vastly different from their private counterparts. Likewise, those in the field face toxic narratives from the government, the media, the public, and their private counterparts alike, resulting in persistent discourse of vilification. Ultimately, it calls for a refocus of legal aid work as a separate vocation due to its altruistic underpinnings, unique ‘professional’ identity, and values.
The missing consensus: An analysis of problem definitions and key motivations in the first zero draft for a global plastics treaty
Authors: Knoblauch Doris , Mederake Linda
Published: October 2024

With the ongoing negotiations for an international legally binding instrument on plastic pollution, including in the marine environment, and the frustration at the end of Intergovernmental Negotiating Committee (INC-3), analyzing the zero draft text, which formed the basis for this negotiation round, is crucial. This analysis examines to what extent the zero draft conveys a clear problem definition as the foundation for an internationally legally binding instrument on plastic pollution. We find that the draft lacks a clear problem definition. Additionally, we investigate how the zero draft balances the focus between marine environments and other affected areas and discusses the implications for governance strategies. We find that the draft focuses particularly on fishing gear and hence has a downstream perspective, while upstream measures are equally important. Furthermore, this study delves into the key motivations driving the treaty negotiations, revealing that health and environmental concerns predominate. In comparing our results with previous research, we align with recent publications analyzing INC submissions and onsite statements. In addition, we identify significant differences in key motivations to tackle the plastic pollution issues between the EU and the international level. These disparities, evident in how health and economic arguments are prioritized, reflect varied approaches to combating plastic pollution across political spheres.
Blowup of cylindrically symmetric solutions for biharmonic NLS
Authors: Gou Tianxiang
Published: October 2024

In this paper, we consider blowup of solutions to the Cauchy problem for the following biharmonic nonlinear Schrödinger equation (NLS),
\begin{equation*}
\text{i } \partial_t u=\Delta^2 u-\mu \Delta u-|u|^{2 \sigma} u \quad \text{in} \,\, \mathbb{R} \times \mathbb{R}^d,
\end{equation*}

where $d \geq 1$, $\mu \in \mathbb{R}$ and $0 \lt \sigma \lt \infty$ if $1 \leq d \leq 4$ and $0 \lt \sigma \lt 4/(d-4)$ if $d \geq 5$. In the mass critical and supercritical cases, we establish the existence of blowup solutions to the problem for cylindrically symmetric data. The result extends the known ones with respect to blowup of solutions to the problem for radially symmetric data.
The Nation on the Corners: The Politics of Street-Naming in Lima during the Second Half of the Nineteenth Century
Authors: Ramón Gabriel
Published: October 2024

Recent studies on the figuration of the nation in nineteenth-century Hispanic America have used sophisticated analyses of different media to suggest that Indigenous references were progressively excluded from urban public space as national symbols. In these spaces, the creole authorities placed themselves and their ancestors centre stage. However, these studies have neglected a highly representative medium: street names. This article demonstrates that street nomenclature was key in figuring the nation in a capital city and shows a different trend from that established using other media. Specifically, after the 1861 municipal reform of street names in Lima, Peru, the majority of official names were Indigenous and did not celebrate creole or military elites. This article examines this reform and the conflicts it provoked.
A semantic visual SLAM based on improved mask R-CNN in dynamic environment

Published: October 2024

To address the issues of low positioning accuracy and weak robustness of prior visual simultaneous localization and mapping (VSLAM) systems in dynamic environments, a semantic VSLAM (Sem-VSLAM) approach based on deep learning is proposed in this article. The proposed Sem-VSLAM algorithm adds semantic segmentation threads in parallel based on the open-source ORB-SLAM2’s visual odometry. First, while extracting the ORB features from an RGB-D image, the frame image is semantically segmented, and the segmented results are detected and repaired. Then, the feature points of dynamic objects are eliminated by using semantic information and motion consistency detection, and the poses are estimated by using the remaining feature points after the dynamic feature elimination. Finally, a 3D point cloud map is constructed by using tracking information and semantic information. The experiment uses Technical University of Munich public data to show the usefulness of the Sem-VSLAM algorithm. The experimental results show that the Sem-VSLAM algorithm can reduce the absolute trajectory error and relative attitude error of attitude estimation by about 95% compared to the ORB-SLAM2 algorithm and by about 14% compared to the VO-YOLOv5s in a highly dynamic environment and the average time consumption of tracking each frame image reaches 61 ms. It is verified that the Sem-VSLAM algorithm effectively improves the robustness and positioning accuracy in high dynamic environment and owning a satisfying real-time performance. Therefore, the Sem-VSLAM has a better mapping effect in a highly dynamic environment.

Iguaçu National Park, a UNESCO World Heritage Site, faces threats from proposed legislation aimed at downgrading its protection to allow reopening of the Caminho-do-Colono road, which would fragment the National Park. This study assesses the National Park’s importance in preserving native vegetation and its economic significance via payments for environmental services. We evaluated different scenarios, demonstrating how these resources are vital for certain municipalities. By comparing economic performance before and after the road’s closure, our findings reveal that, contrary to local beliefs, the closure did not negatively impact the local economy. Additionally, these legislative bills are legally infeasible and fail to offer environmental or economic benefits, favouring small interest groups over the collective good. This research highlights that the Caminho-do-Colono road is not a viable approach to municipal development. Instead, maintaining the National Park’s integrity is crucial for both ecological preservation and economic stability in the region. Our analysis underscores the broader implications of environmental conservation efforts and the necessity of rejecting projects that compromise protected areas. This study provides a comprehensive evaluation of the National Park’s role, emphasizing the need for sustainable development that aligns with environmental and community well-being.
Bioethics and the Value of Human Life
Authors: Häyry Matti
Published: October 2024

Bioethics as a philosophical discipline deals with matters of life and death. How it deals with them, however, depends on the kind of life particular bioethicists focus on and the kind of value they assign to it. Natural-law ethicists and conservative Kantians emphasize biological human life regardless of its developmental stage. Integrative bioethicists also embrace nonhuman life if it can be protected without harming humans. Liberal and utilitarian moralists concentrate on life that is sentient and aware of itself, to the exclusion of biological existence devoid of these. Extinctionist and antinatalist philosophers believe that life’s value is negative and that its misery should be alleviated and terminated by not bringing new individuals into existence. As the last-mentioned approach reverses the idea of life’s positive value, it could be called oibethics.

Objective:

Transthoracic echocardiography is the gold standard method for screening and confirmation of acute rheumatic fever and subclinical rheumatic heart disease. Secondary antibiotic prophylaxis that is regularly employed in subclinical rheumatic heart disease may help to reverse mild rheumatic carditis lesions, delay the progression of the disease, reduce morbidity and mortality, and improve patients’ quality of life.

Materials and Methods:

We retrospectively evaluated the outcomes of 180 patients with subclinical rheumatic heart disease who were followed up for a mean of 4.92 ± 2.0 (3.5–6.5) years.

Results:

Between 1 March 2015 and 31 December 2023, 180 patients diagnosed with subclinical rheumatic heart disease with a mean follow-up of 4.92 ± 2.0 (3.5–6.5) years were included in the study. Of the patients, 50.6% were male, 49.4% were female, mean age at diagnosis was 11.74 ± 3.18 (9.68–13.65) years, and mean follow-up period was 4.92 ± 2.0 (3.5–6.5) years. Further, 87.2 % of the patients had mitral valve regurgitation, 38.3% had aortic valve regurgitation, and 27.2% had both valve (aortic and mitral valve) regurgitation. Moreover, Sydenham chorea was also diagnosed in 7.8% the patients. Of the patients, 90% had mild rheumatic heart disease, 7.8% had moderate rheumatic heart disease, and 2.2% had severe rheumatic heart disease. After the diagnosis of rheumatic heart disease, 76.7% patients received regular and 23.3% irregular secondary benzathine penicillin G prophylaxis.

Conclusion:

We believe that echocardiography demonstrates its efficacy and safety profile in reducing the risk of rheumatic heart disease in patients diagnosed with subclinical rheumatic carditis and complying with regular secondary antibiotic prophylaxis.
Effects of the French grammatical gender system on bilingual adults' perception of objects
Authors: Chen Zhuohan , Faitaki Faidra
Published: October 2024

This study extends the line of linguistic relativity research by assessing the effect of the French grammatical gender system on French speakers' and learners' perception of objects. Four groups of 140 adults (English monolinguals, French monolinguals, English–French bilinguals and French–English bilinguals; N = 35 each) rated 32 selected objects' gender by assigning them a masculine/feminine voice on a slider. We also assessed the participants' second-language (L2) proficiency. Multilevel modelling results revealed that French monolinguals and English–French bilinguals rated objects' gender in line with the French grammatical gender system. The effect of French on perception was not reduced by acquiring English, as French–English bilinguals performed on par with French monolinguals. Moreover, the effect was independent of L2 proficiency. These findings suggest that learning a gendered L2 affects the perception of objects – thus supporting the linguistic relativity hypothesis.
Academic freedom in Europe: Limitations and judicial remedies
Authors: Kovács Kriszta
Published: October 2024

Europe has recently struggled with democratic backsliding and autocratization. This autocratization has accompanied a decline in academic freedom in many backsliding countries, as reported by the Academic Freedom Index. Can the standards set by the European supranational courts effectively safeguard academic freedom? This article provides answers to this question. It argues that despite differences in their approaches, the theoretical conceptions of scholarship held by the European Court of Human Rights (ECtHR) and the Court of Justice of the European Union (ECJ) share an essential feature: both have moved towards embracing the ‘liberal science script’ by protecting academic freedom. The main difference between the two courts’ approaches is the subject of protection. The ECtHR focuses on the individual rights of academics: It protects free speech in the academic context by establishing a high standard for holding academics liable for publicly expressing their views inside and outside of academia. The ECJ has applied the concept of institutional autonomy, thereby setting a high standard for safeguarding the freedom of academic institutions. This standard can be applied with regard to the demands placed by policy-makers on academia regarding its role in democracy, including gender equality requirements for EU research funding.
Exploring the Link Between Parental Sociodemographic Characteristics and Multiple Births: Insights from National Birth Data in Japan, 1995–2020
Authors: Okui Tasuku , Nakashima Naoki
Published: October 2024

This present study investigated the parental characteristics of multiple births using national birth data in Japan. This study included birth data from Vital Statistics: Occupational and Industrial Aspects every five fiscal years from 1995 to 2020. The multiple birth rates were defined as the number of live-birth deliveries with multiple fetuses (e.g., twins, triplets) per total live-birth deliveries. Parental ages, nationalities, occupations and household occupation (occupation of the top earner of the household) were considered as parental characteristics. The multiple birth rates were calculated based on parental characteristics for each year, and a log-binomial regression model was used to assess the association between parental characteristics and multiple births. The multiple birth rate for Japanese mothers consistently exceeded that for non-Japanese mothers over the years, and the rate increased progressively from manual workers to lower non-manual workers and then to upper non-manual workers for both maternal and paternal occupations. The regression results indicated that the risk ratio (RR) for multiple births among non-Japanese mothers was significantly lower than that among Japanese mothers. Moreover, concerning household occupation, the RRs of self-employed individuals, full-time employees at smaller companies, others, and the unemployed were significantly lower than those of full-time employees at larger companies. Furthermore, the RRs of lower non-manual and manual workers were significantly lower than those of upper non-manual workers in maternal and paternal occupations. The results suggested an association between multiple births and parental socioeconomic status in Japan.
