Published: July 2024

AbstractWhole slide imaging (WSI) of pathology glass slides using high‐resolution scanners has enabled the large‐scale application of artificial intelligence (AI) in pathology, to support the detection and diagnosis of disease, potentially increasing efficiency and accuracy in tissue diagnosis. Despite the promise of AI, it has limitations. ‘Brittleness’ or sensitivity to variation in inputs necessitates that large amounts of data are used for training. AI is often trained on data from different scanners but not usually by replicating the same slide across scanners. The utilisation of multiple WSI instruments to produce digital replicas of the same slides will make more comprehensive datasets and may improve the robustness and generalisability of AI algorithms as well as reduce the overall data requirements of AI training. To this end, the National Pathology Imaging Cooperative (NPIC) has built the AI FORGE (Facilitating Opportunities for Robust Generalisable data Emulation), a unique multi‐scanner facility embedded in a clinical site in the NHS to (1) compare scanner performance, (2) replicate digital pathology image datasets across WSI systems, and (3) support the evaluation of clinical AI algorithms. The NPIC AI FORGE currently comprises 15 scanners from nine manufacturers. It can generate approximately 4,000 WSI images per day (approximately 7 TB of image data). This paper describes the process followed to plan and build such a facility. © 2024 The Author(s).

Published: July 2024

AbstractReal-time Earth Orientation Parameters (EOP) are crucial in various space geodetic applications, from satellite navigation to weather forecasting. This study introduces a refined prediction package leveraging diverse EOP series from the Federal Agency of Cartography and Geodesy (BKG), including rapid and final series, Satellite Laser Ranging (SLR) series, and International Earth Rotation and Reference Systems Service (IERS) C04. Our approach yields substantial improvements in EOP prediction accuracy. Results highlight superior performance in critical parameters such as Polar Motion, (UT1-UTC) dUT1, and Length of Day (LOD) predictions. Notably, our predictions surpass benchmarks from the Second EOP Prediction Comparison Campaign (2nd EOP-PCC)” organized by International Association of Geodesy (IAG) and IERS, showcasing the effectiveness of our methodology. Additionally, BKG’s Rapid EOP stands out with remarkable accuracy, featuring a shorter latency of 1 to 2 days. This study contributes to our understanding of Earth’s rotational dynamics. It provides practical advancements in real-time EOP predictions, demonstrating the potential impact on a wide range of scientific and operational applications.
Densification of the IHRF in Denmark, The Faroe Islands, and Greenland

Published: July 2024

AbstractThe International Association of Geodesy (IAG) introduced and defined, in 2015, the International Height Reference System (IHRS) as the conventional reference system for the global physical height determination. Following the conventions for the realisation of the IHRS, i.e. the determination of the International Height Reference Frame (IHRF), we utilize the existing GNSS reference stations in Denmark, The Faroe Islands, and Greenland to determine a local densification of the IHRF in these regions. The physical heights of these Danish, Faroese and Greenlandic GNSS reference stations have been transformed from the local Danish, Faroese, and Greenlandic height systems, DVR90, FVR09 and GVR16, respectively, to geopotential numbers and normal heights referring to the IHRF. The offset to the IHRF is found to be −44.0 ± 1.9 cm, −59.8 ± 5.1 cm and − 54.1 ± 11.3 cm for the DVR90, FVR09 and GVR16, respectively. This transformation relies on the existing precise local (quasi-)geoid models. This contribution describes the applied procedures in the IHRF densification and discusses the quality assessment of the results.
The Impact of Different Geophysical Corrections on Altimetry-Derived Sea Level Rise Estimates—Wet Troposphere
Authors: Dettmering Denise , Schwatke Christian , Müller Felix L. 
Published: July 2024

AbstractSatellite radar altimetry has been providing sea surface heights on an almost global scale for the past 30 years. From this data, an average global mean sea level rise of 3-4 mm per year can be estimated. To determine these small changes with high accuracy, precise and stable measurements are required. Long-term data stability is particularly important for sea-level rise applications. This not only relates to the altimeter measurements themselves, but also to any geophysical correction applied to the data. Furthermore, consistency between different missions is essential to ensure a long time series that is useful for climate studies.This contribution shows how global sea level rise estimates can be affected by geophysical corrections applied to satellite altimetry data and the importance of selecting the right datasets. The focus will be on atmospheric corrections, especially on different wet troposphere path delay corrections derived by models and observations. It will be shown that these corrections can introduce systematic errors in the order of 0.5 mm/year, which is the level of uncertainty currently assumed for the altimetry-derived global mean sea level trend.
Data Sharing Is Caring: Crisis-Induced Realisation of Open Access Policy in a PhD Project on Food Practices
Authors: Ciren Baizhen 
Published: July 2024

AbstractCross-cultural and comparative research is becoming increasingly relevant in the field of food studies. However, the COVID-19 pandemic made travel and research visits impossible. The European Union (Berlin Declaration. Berlin declaration on open access to knowledge in the sciences and humanities. Retrieved from https://openaccess.mpg.de/67605/berlin_declaration_engl.pdf, 2003) has long postulated the necessity of research data sharing and preventing data waste. Using the cultural-historical wholeness approach to reflect on the example of the methods employed by a comparative PhD project on kindergarten lunch practices in Norway and China, this chapter shows how the crisis of the impossibility of directly conducting research (due to the outbreak of the pandemic) activated the data-sharing policy. This chapter argues that with careful consideration of epistemological, ethical, and methodological issues, data sharing in qualitative research can be beneficial for researchers, the scholarly community and the public and can help promote a research culture of sustainability in the long run.
Theoretical Framing of a Digital Education Experiment
Authors: Fleer Marilyn , Fragkiadaki Glykeria , Ødegaard Elin Eriksen , Rai Prabhat , Sadownik Alicja 
Published: July 2024

AbstractAn educational experiment as a method was originally theorised as the study of a theoretical problem in practice in a context of a collaboration between researchers and teachers. But when teachers and researchers are not able to be physically together because of government guidelines restricting access, suspending research in schools and centres, or by reducing movement of a population through ‘lock down’, then how can an educational experiment be undertaken? The richness of the concrete research methods that follow are theorised through bringing together a system of concepts that enable a digital educational experiment to proceed under conditions of crisis, contradiction, and drama. Named as a digital educational experiment, the theorised model draws on Vygotsky’s original core conception of development, Hedegaard’s writings on an educational experiment, and the new methods presented in Sect. 2.1. It builds on the concepts of motives and demands in relation to digital environments and interactions, where time, space, and physicality are virtually defined and enabled.
Theorization on the Nexus of Crisis, Resilience, and Digital Agility
Authors: Ødegaard Elin Eriksen , Fleer Marilyn , Fragkiadaki Glykeria , Rai Prabhat , Sadownik Alicja R. 
Published: July 2024

AbstractThis section introduction will study the nexus of crisis, resilience, and digital agility, drawing on the knowledge from the section paper. The concepts of resilience and agility are both social and personal. We lean on Dafermos (Rethinking cultural-historical theory: a dialectical perspective to Vygotsky. Springer, Singapore, 2018), who, with reference to Vygotsky’s research, stated that the underestimation of the problem of personality was one of the basic shortcomings of his own research program. This section increases our theoretical understanding of the ways in which the personal (motivation, traits, e.g. engagement, and capabilities in individuals), institutional, and societal are entwined. We sum up the metaknowledge of the chapters by presenting a model pinpointing Resilient Digital Agility with three crucial actions; recover, respond, reimagine and recraft.
The Individual and Collective Minds Behind the Role of the Educator-Researcher: An Integrated Educational Experiment
Authors: Meng Xianyu 
Published: July 2024

AbstractAn educational experiment was introduced by Hedegaard (Studying children: A cultural-historical approach. Open University Press, New York, 2008a) as a synthesis of pedagogical intervention and research method. The planned intervention is designed collaboratively between teachers and researchers to supports children’s learning and development. But what happens when the researcher also assumes the role of the educator? This chapter presents an example of an educational experiment that was undertaken individually by an educator-researcher. To support the educational experiment, a collective of PhD supervisors and the other intellectual colleagues acted as an expansive community that enabled theoretical discussions and data analysis to be performed at an interpsychological level. It was found that with digital video observation as the main research method, the dialectical relations between the individual and the collective created unique opportunities for the formation of the researcher’s identity, as well as fulfilling the research aim of the educational experiment. Thus a new configuration of the educational experiment is proposed as an enabling research method, where an educator-researcher used digital video observations, and an expansive intellectual community for peer review.
Researcher Inside a Diorama: A Digital Educational Experiment in Everyday Practices
Authors: Parkes Monique 
Published: July 2024

AbstractYoung children develop conceptual understandings in science from early infancy and through involvement in various institutions and activity settings. Daily interactions with peers, families, care givers, early childhood educators and teachers create conditions for young children to enhance their conceptual learning and theoretically model their understandings. However, not enough is understood about how children 5 years and under use theoretical modelling to represent their thinking in science. Recognising this gap necessitates research that applies suitable tools and, a methodology to capture and understand young children’s scientific concept formation and theoretical modelling. This chapter will discuss the use of digital methodologies and multiple strategies initiated during the Covid19 crisis. These include dioramas, drawing, and three-dimensional modelling in an educational experiment to gain deeper insights into the theoretical modelling of young children in early childhood settings involving the scientific concept of light. Importantly, the advantageous use of digital tools will be explained as a method enabling researchers to actively apply other creative tools and to participate in the children’s activity settings towards the acquisition of authentic data for analysis.
Early Childhood Teachers’ Professional Development: The Hybrid Educational Experiment
Authors: Li Liang 
Published: July 2024

AbstractIn recent years, particularly in the ‘new normal’ period, social media has been widely used as a vital part of professional learning and communication. Nevertheless, there is limited research on educational experiment in terms of how social media–based professional development can be promoted to support physical meetings for teacher professional learning. We examine the functions of social media, such as WeChat, in the hybrid educational experiment, using Vygotsky’s ideas of social situation of development and crisis and Edwards’s concept of relational agency. We engage in theoretical discussion through the analysis of illustrative vignettes from the previous study conducted with three kindergarten teachers in different facilities in China. We argue that the hybrid educational experiment through social media (e.g., WeChat) and face-to-face professional development training creates motivating conditions to support teachers’ meaningful professional development and promote professional agency. The hybrid educational experiment also enables researchers to understand the process of teachers’ professional development and traverses the complex, shifting and uncertain areas of pedagogical roles and practices. The study reveals that engaging with social media (e.g., WeChat) provides the research foundations to capture teachers’ professional agency in a new way and process teachers’ sustainable professional development in play-based learning programs.
Dialectical Pathways in Digital Data Analysis
Authors: Fragkiadaki Glykeria , Fleer Marilyn , Ødegaard Elin Eriksen , Rai Prabhat , Sadownik Alicja R. 
Published: July 2024

AbstractIn recent times of crisis, contradictions, and drama researchers stood in front of a labyrinth of multiple methodological choices and imponderable research paths and directions. In many cases, this new reality created the opportunity for the researchers to think in novel and innovative ways by involving in a critical, dialectical, and open-ended “dialogue” with their data and the analytical processes. Part II brings together four indicative examples of research labyrinths and the new methodological frameworks the researchers invented to step their way out of them. It is argued that dialectics and dialectical thinking opened new spaces for reflection and allowed new dimensions of digital analysis to emerge. Through the Chapters of the Section, it is shown how researchers developed their creative imagination by focusing on new units of analysis and uses of digital means, how they strengthened their methodological agency by inventing new methods, and how they developed their personalities as researchers through new motives and values. This complex and unique in each case process is discussed in this Chapter as a socially and culturally oriented process in motion.

Authors: Harnoncourt L. , Gstoettner C. , Pflaum L. , Laengle G. , Aszmann O. C. 
Published: July 2024

Zusammenfassung
Hintergrund
Die prothetische Versorgung nach einer Amputation der unteren Extremität geht mit einigen Herausforderungen einher. Skeletale Stumpf-Prothesen-Schnittstellen und selektive Nerventransfers können diese teilweise bewältigen, bringen jedoch auch Einschränkungen, die die Notwendigkeit neuer Ansätze unterstreichen, mit sich. Hier kann das Konzept der sog. Ersatzteilchirurgie mit der Nutzung von Filetlappen eine wichtige Rolle spielen.

Fragestellung
Übersicht über die klassischen prothesenassoziierten Beschwerden, Vor- und Nachteile von Versorgungsstrategien sowie Präsentation alternativer chirurgischer Konzepte.

Material und Methoden
Es erfolgte eine selektive Literaturrecherche unter Berücksichtigung eigener Erfahrungen und Ansichten bezüglich Vor- und Nachteilen der chirurgischen Versorgungsmöglichkeiten. Zusätzlich wird ein klinischer Patientenfall vorgestellt.

Ergebnisse und Schlussfolgerung
Der Transfer der Fußsohle als Filetlappen in die Belastungszone des Amputationsstumpfes geht mit einer Vielzahl von Vorzügen wie Endbelastbarkeit des Stumpfes, Vorbeugen von Nervenschmerzen, erhaltener Sensibilität und Bewahren des Körperbilds einher. Die Technik kann bei Amputationen sowohl proximal wie auch distal des Kniegelenks eingesetzt werden, vorausgesetzt, dass die Fersenregion nicht beeinträchtigt ist. Die Frage, ob Anteile des Knochens in den Transfer einbezogen werden soll, ist bei jedem Patienten individuell zu evaluieren. Dieser Ansatz ermöglicht die Optimierung des Amputationsstumpfes für die nachfolgende prothetische Versorgung der Patienten.
Advancing quality of laser-based metal powder bed fusion-fabricated filigree sub-millimetre structures: a systematic exploration of a novel hybrid post-processing treatment

Published: July 2024

AbstractLaser-based metal powder bed fusion (PBF-LB/M) offers great potential for producing complex and filigree sub-millimetre parts with customised shapes, such as patient-specific vascular stents. However, stent fabrication via PBF-LB/M encounters fundamental challenges, including dimensional limitations, poor surface quality, difficult support structure handling and geometrical deviations.This study addresses these challenges by investigating the potential and limitations of a novel hybrid post-processing approach. This technique uses the combination of electrochemical polishing and chemical etching and is investigated from process and design perspectives, to emphasise the interactions between the two.With the systematic application of hybrid post-processing, the strut thickness and the surface roughness were substantially reduced. Moreover, it enabled the successful removal of part-internal support structures. Furthermore, angle and orientation-dependent geometrical deviations could be compensated, highlighting the potential of achieving homogenous strut thicknesses within parts containing variable overhang angles.This study demonstrates that the usage of hybrid (electro)chemical post-processing methods with specifically tailored process parameters is a promising approach for overcoming the design- and process-related challenges in PBF-LB/M manufactured sub-millimetre parts.

Published: July 2024

Abstract

Background
The most deadly type of spontaneous intracerebral hemorrhage is spontaneous cerebellar hemorrhage (SCH). The purpose of this meta-analysis was to investigate risk factors for prognosis in SCH patients to provide a basis for taking preventive and therapeutic measures.

Methods
Seven electronic databases were searched from inception to May 2023 for randomized controlled trial, cohort study, case control study and cross-sectional study on prognosis of spontaneous cerebellar hemorrhage. The quality of the selected studies were assessed by the American Agency for Healthcare Research and Quality (AHRQ). To assess the impact of the included risk factors on the prognosis of spontaneous cerebellar hemorrhage, combined odds ratios (ORs) with matching 95% confidence intervals (CIs) were combined.

Results
Eight studies were included, including 539 participants. And a total of 31 potentially associated risk factors were identified. Ultimately, 6 risk factors were included in the meta-analysis after assessing. The factors supported by moderate evidence include the hydrocephalus (OR = 4.3, 95% CI: 2.33 to 7.91) and drug-induced coagulopathy (OR = 2.74, 95% CI: 1.23 to 6.09). The factors supported by limited evidence include the intraventricular bleeding(OR = 1.86, 95% CI: 1.13 to 3.07) and hematoma size>3 cm(OR = 3.18, 95% CI: 1.87 to 5.39). Meta-analysis revealed no association between hypertension, diabetes mellitus and SCH prognosis.

Conclusion
The current meta-analysis revealed obvious risk factors for prognosis in spontaneous cerebellar hemorrhage patients, including hydrocephalus, drug-induced coagulopathy, intraventricular bleeding and hematoma size>3 cm.
Individualist-collectivist profiles in secondary school: an exploratory study of trait emotional intelligence and academic achievement
Authors: Costa Ana , Faria Luísa 
Published: July 2024

AbstractAn individualist (I) or collectivist (C) cultural orientation affects individuals’ attitudes, behaviours and values. This study aimed to identify the first-year secondary-school students’ I–C profiles and explore their implications for students’ trait emotional intelligence (EI), emotions towards school and academic achievement (GPA) throughout the 3-year secondary-school cycle. A total of 222 secondary-school students (58.6% females; Mage = 15.4; SD = .63 in the 10th grade) were enrolled in a longitudinal study. The cluster analysis identified three distinct I–C profiles: high individualist-low collectivist students, low individualistic-midlevel collectivist students and high individualist–high collectivist students. The results revealed significant differences between the I–C profiles regarding students’ trait EI, emotions towards school and GPA throughout secondary school, in particular favouring the high individualist–high collectivist profile. These findings are discussed based on the practical implications for students’ outcomes in the current secondary school system.
