Authors: Erler Martin , Langula Sebastian , Wölfel Christian , Schneider Julia , Kunath Christiane , Königs Michael 
Published: May 2024

AbstractWe present a data-driven approach to support decision-making in CAD modelling and to improve design for manufacturing. Based on automated estimated production planning, information is provided on possible design actions and their impact. A study was conducted on perspectives on and visualizations in CAD modelling. Requirements for a user interface of the described support system were identified. The results serve as basis for further research and development on the interaction of engineering designers with data-driven decision-making support in CAD modelling.

AbstractThis paper examines upgradability through modular product design, aiming to extend lifecycles and promote cross-generational use. It builds up on a preceding work, a systematic literature- review identifying four fields of action in future-robust product design. The paper itself contains an in-depth interview study with 17 experts from industry and research to validate and expand the literature-based fields of action. The results provide insights into the application and employment of future-robust product design, with a focus on adaptable product architectures.
Engineering designers’ CAD performance when modelling from isometric and orthographic projections
Authors: Lukačević Fanika , Becattini Niccolò , Škec Stanko 
Published: May 2024

AbstractThe presented study investigates differences in engineering designers' CAD performance when modelling from two types of projections in technical drawings – isometric and orthographic. The results revealed significant differences in the percentage of correctly replicated components' size and shape, indicating better CAD outcomes when generating CAD models from the orthographic projection. In addition, a comparison of duration, as well as the number and type of sketch entities, sketch relations, and CAD features, showed that CAD modelling processes were similar in both conditions.

Published: May 2024

AbstractLab-on-a-Chip (LOC) products for point-of-care diagnostics have gained significant attention. However, there is a lack of systematic approaches for LOC product development. To address this, we introduce an Attribute Dependency Graph exemplary for a magnetophoretic LOC system for pathogen detection. This model organizes dependencies between the design variables and crucial quantities of interest, such as detectability, cost per test, and test duration. The obtained model helps to manage design complexity and can be adapted to other LOC approaches.
A model to describe logistics service architecture based on product architecture
Authors: Strøm Erika Marie , Münsberg Tine Meidahl , Hvam Lars 
Published: May 2024

AbstractThe growth in e-commerce has led to increased demand for logistics services. This puts a pressure on third-party logistics (3PL) providers who struggle with increasing operating costs and heightened competition. These providers could potentially exploit the advantages of modularisation, but few studies address the design of modular logistics services. This study explores modular design of logistics services and proposes a model to describe logistics service architecture based on product architecture. A case study shows that warehousing services can be described in three domains.

Published: May 2024

AbstractThis study explores the alignment between automotive design innovation and consumer acceptance, particularly in the context of two significant trends: electrification and digitalization. We probed the acceptance of replacing rear window with wide-angle camera We surveyed 1,546 potential customers from China and Sweden to assess their openness to such a radical design. Findings suggest a consensus on its futuristic appeal but diverge in adoption willingness. The study offers insights to bridge the design preference gap, positioning customer acceptance as key for car design strategy.
Human- and design-centric source: comparison using requirements checklist
Authors: Naik Gouri , Srinivasan V. 
Published: May 2024

AbstractThe overall aim is to assess the superior of human- or design-centric source. This research compares the categories covered in a checklist by pain-points and needs identified individually using human- and design-centric sources. Data from 6 projects of a design course is used. It is found that there is no significant difference in the number of categories covered by pain-points and needs but the categories are not the same. This calls for integrating both sources in comparison to using only one source for designing which can potentially help to identify diverse and relevant outcomes.
Breaking cultural barriers: an integrated methodology for challenge-driven co-creation projects
Authors: Bastian Annika , Kempf Christoph , Rudolph Paulin , Albers Albert 
Published: May 2024

AbstractThe fact that successful Industry-Academia Collaborations (IACs) are beneficial for the participants is widely accepted. However, without a target-oriented methodology, the chances for success are low. This paper's focus is the early phase in the creation of such a methodology which is done in a structured way. Furthermore, the goal is to understand the great influence culture plays in creative problem-solving in distributed teams in IACs.
Narrative drives design decision-making
Authors: Ferguson Scott , Retzlaff Lisa , Bryden Kris , Bryden Kenneth Mark 
Published: May 2024

AbstractScholars in economics, psychology, and business have recently defined narrative as the underlying mechanism by which humans internally process information and drive a decision forward. In this paper, we study narrative's use in design across Design Society publications. We discuss how narrative's role as the driver of design decision-making is an important, but missing, element of the design literature. We explain how engineers will be expected to move the design process forward despite facing decisions where the information is simultaneously too much to process, conflicting, and incomplete.

The Role of Copyright Law in the Attainment of Inclusive and Equitable Quality Education in English-Speaking West African Countries
Authors: Olubiyi Ifeoluwa Ayokunle , Khali Allahmagani 
Published: May 2024

AbstractEducation is a prerequisite for the attainment of sustainable development, with multiplier effects on society. This study examines the possibility of achieving inclusive and equitable education under the UN Sustainable Development Goal (SDG) 4, AU Agenda 2063 and ECOWAS Vision 2050. Copyright plays an essential role in either encouraging or barring access to educational materials, which are necessary for the attainment of SDG 4. Through a desk study using the laws and policies of English-speaking West African countries (Gambia, Ghana, Liberia, Nigeria and Sierra Leone), the article examines the copyright laws of these jurisdictions in order to determine how they facilitate or stop access to knowledge. It finds that most of the jurisdictions (except Nigeria) have not maximized the flexibilities available for access to knowledge through copyright limitations and exceptions, thereby barring access to educational materials. It recommends a review of national copyright legislations in line with a developmental perspective.
Mediation and the Structural Interdict as Legal Options to Resolve Service Delivery Failures in South Africa
Authors: Wright Johandri 
Published: May 2024

AbstractSouth African municipalities are entrusted to perform various functions, including providing basic services to communities. Recently, the auditor-general has raised concern about municipalities’ overall functionality and ability to fulfil their obligations. Municipalities’ service delivery failures have led to disputes between them and their communities. Moreover, South African courts have drawn attention to the impact of service delivery failures and described their catastrophic and devastating effects on communities and their local economies. In addition, it is said that the consequences of these municipal failures are more severe for the communities than any other stakeholder. For this reason, communities require legal options to resolve such disputes. This article puts forward two legal options (and potentially a third) to which communities can turn. The article examines mediation and structural interdicts and argues why these options are suitable methods for resolving disputes between a community and its municipality.
Direct stellarator coil design using global optimization: application to a comprehensive exploration of quasi-axisymmetric devices
Authors: Giuliani Andrew 
Published: May 2024

Many stellarator coil design problems are plagued by multiple minima, where the locally optimal coil sets can sometimes vary substantially in performance. As a result, solving a coil design problem a single time with a local optimization algorithm is usually insufficient and better optima likely do exist. To address this problem, we propose a global optimization algorithm for the design of stellarator coils and outline how to apply box constraints to the physical positions of the coils. The algorithm has a global exploration phase that searches for interesting regions of design space and is followed by three local optimization algorithms that search in these interesting regions (a ‘global-to-local’ approach). The first local algorithm (phase I), following the globalization phase, is based on near-axis expansions and finds stellarator coils that optimize for quasisymmetry in the neighbourhood of a magnetic axis. The second local algorithm (phase II) takes these coil sets and optimizes them for nested flux surfaces and quasisymmetry on a toroidal volume. The final local algorithm (phase III) polishes these configurations for an accurate approximation of quasisymmetry. Using our global algorithm, we study the trade-off between coil length, aspect ratio, rotational transform and quality of quasi-axisymmetry. The database of stellarators, which comprises approximately 200 000 coil sets, is available online and is called QUASR, for ‘quasi-symmetric stellarator repository’.
The Seventh Dalai Lama's residence in Kham: Gartar Monastery interactions with indigenous chiefs and the Qing court
Authors: Tsomu Yudru , Chashingtsang Bugang 
Published: May 2024

AbstractThe Seventh Dalai Lama's residence at Gartar Monastery, which began in 1730, greatly affected the relationship between the Kham region and the Tibetan government as well as the Qing court's control over Kham. The Dalai Lama's interactions with various indigenous leaders, local monasteries, monks and lay people increased the influence of the Geluk school in Kham, and also inspired their support for the Dalai Lama. Measures adopted by the Qing court to protect the Dalai Lama, such as stationing troops and inspecting checkpoints, also strengthened Qing control of Kham. After the Dalai Lama left for Tibet in 1735, Gartar Monastery continued to serve as a religious and cultural centre of northern Kham, with the purpose of “civilizing” and “enlightening” the neighbouring regions that were far away from the political centre. Successive abbots of Gartar Monastery – right up to 1920 – came from Drepung Monastery in Lhasa; they and the Gartar monks influenced, interfered with and controlled the local affairs of Gartar and other regions in Kham. In particular, in the late nineteenth and early twentieth centuries, Gartar Monastery, together with the Tibetan commissioner in Nyarong, was able to assist in the Tibetan government's efforts to extend its sphere of influence in Kham.

Published: May 2024

Abstract

Objectives
Patients with hematological malignancies are likely to develop hypogammaglobulinemia. Immunoglobulin (Ig) is commonly given to prevent infections, but its overall costs and cost-effectiveness are unknown.

Methods
A systematic review was conducted following the PRISMA guidelines to assess the evidence on the costs and cost-effectiveness of Ig, administered intravenously (IVIg) or subcutaneously (SCIg), in adults with hematological malignancies.

Results
Six studies met the inclusion criteria, and only two economic evaluations were identified; one cost-utility analysis (CUA) of IVIg versus no Ig, and another comparing IVIg with SCIg. The quality of the evidence was low. Compared to no treatment, Ig reduced hospitalization rates. One study reported no significant change in hospitalizations following a program to reduce IVIg use, and an observational study comparing IVIg with SCIg suggested that there were more hospitalizations with SCIg but lower overall costs per patient. The CUA comparing IVIg versus no Ig suggested that IVIg treatment was not cost-effective, and the other CUA comparing IVIg to SCIg found that home-based SCIg was more cost-effective than IVIg, but both studies had serious limitations.

Conclusions
Our review highlighted key gaps in the literature: the cost-effectiveness of Ig in patients with hematological malignancies is very uncertain. Despite increasing Ig use worldwide, there are limited data regarding the total direct and indirect costs of treatment, and the optimal use of Ig and downstream implications for healthcare resource use and costs remain unclear. Given the paucity of evidence on the costs and cost-effectiveness of Ig treatment in this population, further health economic research is warranted.
How Do Toothless Tigers Bite? Extra-institutional Governance and Internet Censorship by Local Governments in China
Authors: Zhang Tony Huiquan , Xu Jianhua , Liu Jinjin 
Published: May 2024

Abstract
China has constructed a rigorous state apparatus to control its online social content. To date, research has largely focused on the central government's cyber control, but the less studied local cyberspace administrative forces are also important. Our fieldwork and interviews at a county-level cyberspace administration office (CAO) in east China reveal that the local CAO had been rendered a “toothless tiger” with insufficient technology, power and labour. However, it has made up for these deficiencies by utilizing systems such as outsourced surveillance, organized mass reporting and personnel secondment. We contend that these practices, which we label “extra-institutional governance” (EIG), emerge when bureaucracies with limited resources face external pressures. The findings shed light on how censorship machines operate in local governments in China and reveal the general dynamics of how bureaucratic organizations adapt to environmental pressures.
Full-length transcriptome and co-expression network analysis reveal molecular mechanisms of seed development in Elymus sibiricus

Published: May 2024

AbstractGrass seeds play a critical and fundamental role in grass breeding and production. Elymus sibiricus L. is a widespread Poaceae forage grass in northern Eurasia which is used for ecological restoration and forage production. Sucrose is the main source of substrate and energy required for starch synthesis in the seeds, so the hydrolysis of sucrose determines and influences starch synthesis and filling in the seeds, especially Poaceae. However, the process behind carbohydrate metabolism during E. sibiricus seed development remains unclear. This study addresses a significant gap in our understanding of the carbohydrate metabolism during seed development in E. sibiricus by employing full-length transcriptome sequencing across five developmental stages for the first time. Full-length transcriptome sequencing was performed on E. sibiricus seeds at five developmental stages (S5, S9, S15, S20, S25) to get better molecular insights. We identified 13,205 differentially expressed genes, with 7,471 up-regulated and 5,734 down-regulated. Through KEGG enrichment analysis, genes were enriched in ‘starch and sucrose metabolism’, ‘photosynthetic-related’ and ‘hormone signal transduction’ pathways. Gene ontology enrichment analysis showed that genes were enriched in the ‘beta-amylase activity’ term of molecular functions. In addition, top 21 transcription factor families were identified as involved in seed development. The homologous genes of ABSCISIC ACID-INSENSITIVE 3 (ABI3), NUCLEAR FACTOR-YB1 (NF-YB1), STARCH SYNTHASE I (SSI) were identified as candidate genes of seed development in E. sibiricus. Combined with physiological index, transcriptome analyses, weighted gene co-expression network analysis and real-time quantitative PCR, the mechanism of starch and sucrose content of seed development was revealed and ten hub genes were identified. Overall, this study provides the molecular bases to understand seed development and starch and sucrose metabolism at the different seed developmental stages in E. sibiricus.

AbstractIntroduction:Acute kidney injury is associated with worse outcomes after cardiac surgery. The haemodynamic goals to ameliorate kidney injury are not clear. Low post-operative renal perfusion pressure has been associated with acute kidney injury in adults. Inadequate oxygen delivery may also cause kidney injury. This study evaluates pressure and oximetric haemodynamics after paediatric cardiac surgery and their association with acute kidney injury.Materials and Methods:Retrospective case–control study at a children’s hospital. Patients were < 6 months of age who underwent a Society of Thoracic Surgery-European Association for Cardio-Thoracic Surgery Congenital Heart Surgery categories ≥ 3. Low renal perfusion pressure was time and depth below several tested thresholds. The primary outcome was serum creatine-defined acute kidney injury in the first 7 days.Results:Sixty-six patients (median age 8 days) were included. Acute kidney injury occurred in 36%. The time and depth of renal perfusion pressure < 42 mmHg in the first 24 hours was greater in acute kidney injury patients (94 versus 35 mmHg*minutes of low renal perfusion pressure/hour, p = 0.008). In the multivariable model, renal perfusion pressure < 42 mmHg was associated with acute kidney injury (aOR: 2.07, 95%CI: 1.25–3.82, p = 0.009). Mean arterial pressure, central venous pressure, and measures of inadequate oxygen delivery were not associated with acute kidney injury.Conclusion:Periods of low renal perfusion pressure (<42 mmHg) in the first 24 post-operative hours are associated with acute kidney injury. Renal perfusion pressure is a potential modifiable target that may mitigate the impact of acute kidney injury after paediatric cardiac surgery.
META-CLASSICAL NON-CLASSICAL LOGICS
Authors: BARRIO EDUARDO , FIORE CAMILLO , PAILOS FEDERICO 
Published: May 2024

AbstractRecently, it has been proposed to understand a logic as containing not only a validity canon for inferences but also a validity canon for metainferences of any finite level. Then, it has been shown that it is possible to construct infinite hierarchies of ‘increasingly classical’ logics—that is, logics that are classical at the level of inferences and of increasingly higher metainferences—all of which admit a transparent truth predicate. In this paper, we extend this line of investigation by taking a somehow different route. We explore logics that are different from classical logic at the level of inferences, but recover some important aspects of classical logic at every metainferential level. We dub such systems meta-classical non-classical logics. We argue that the systems presented deserve to be regarded as logics in their own right and, moreover, are potentially useful for the non-classical logician.
Localized Tidal Energy Extraction in Puget Sound Can Adjust Estuary Reflection and Friction, Modifying Barotropic Tides System‐Wide
Authors: Spicer Preston , MacCready Parker , Yang Zhaoqing 
Published: May 2024

AbstractHarvesting energy via tidal stream turbines is being increasingly considered as a renewable energy resource in estuaries with strong tidal currents. It remains unclear how localized energy extraction changes basic tidal physics throughout real systems. Here, we analyze the influence of an extensive synthetic tidal turbine array on barotropic tides in the Salish Sea, a complex, tidally energetic estuary, using a realistic numerical model. Tidal energy fluxes are calculated at 15 sections throughout the system and decomposed into incident and reflected components, as well as by frequency. Results show the dominant semidiurnal constituent, M2, controls the total tidal energy flux everywhere. When turbines are placed in Tacoma Narrows, the M2 energy flux is enhanced at sections seaward of the array in Puget Sound and reduced landward. The principal diurnal constituent, K1, contributes little to the total energy flux, but behaves similarly. Changes to each constituent are primarily attributed to turbine enhanced frictional dissipation which reduces the estuary's natural resonant period (∼10 hr) amplification. Being close to the semidiurnal frequencies, the resonance adjustment reduces M2 tidal reflection seaward of the turbines and free surface amplitude (particularly landward of the turbines) thereby increasing (decreasing) tidal energy fluxes at seaward (landward) locations. K1 is further from the natural frequency and insensitive to resonance changes. We hypothesize K1 is directly sensitive to increased frictional dissipation which acts to reduce reflection and tidal amplitude, regardless of the estuary natural frequency. Spatial variability in dynamics is discussed, as well as potential environmental implications.
