Fons et origo: reflections on the 60th anniversary ofIndustrial Dynamics
Authors: Lane David C. 
Published: October 2022

AbstractThis paper records and reflects on the anniversary of the publication of Forrester'sIndustrial Dynamics. It considers the book from four perspectives. First, it samples the earlier publications that heralded and anticipated its publication. Second, it explores in depth some contemporary reviews, drawn from a range of disciplines. The paper then looks in detail at how the book was influenced by, and itself influenced, three neighbouring areas: MS/OR, system science and the social sciences, and ‘problem structuring methods’. Fourth, to further place the book in context, the paper considers in brief the varied life of Forrester himself, indicating how his experiences informedIndustrial Dynamics. The paper closes by recapitulating the importance ofIndustrial Dynamicsas the founding publication of the system dynamics field. © 2022 The Author.System Dynamics Reviewpublished by John Wiley & Sons Ltd on behalf of System Dynamics Society.
Experimental methods for the analysis of the durability behavior of concrete joints
Authors: Höffgen Jan P. , Mohs Matthias , Lamparter Sarah , Malárics‐Pfaff Viktória , Dehn Frank 
Published: October 2022

AbstractThis article addresses the applicability of experimental methods for the evaluation of concrete durability on localized structural weaknesses posed by joints. Three different types of exposure are analyzed: chloride penetration, carbonation, and freeze–thaw attack. First, established experimental methods for the characterization of the durability of plain concrete are presented and their general applicability on concrete joints is discussed. The experimental program focuses on the execution of selected tests on laboratory specimens with and without joints. Indicator tests for both chloride penetration and carbonation are generally feasible, but require attention to specimen preparation. Rapid chloride migration yielded inconclusive results, while uniaxial chloride diffusion coefficient of concrete joints cannot be determined because of the areal extent of profile grinding. For the same reason, the characterization of the resistance to freeze–thaw cycles through surface deterioration is not applicable for concrete joints. The structural damage was instead successfully qualified through direct tension tests.
Phosphorus based hybrid materials for green fuel generation
Authors: Ghosh Srabanti , Bera Susmita , Samajdar Soumita , Pal Sourabh 
Published: October 2022

AbstractPhosphorene, also referred to as phosphorus‐based elemental material (black and red), display unusual electronic‐structure characteristics, which can significantly enrich the fields of energy application and possesses huge potential in photocatalysis owing to its bandgap tunability, high optical absorption, large surface area, high charge carrier mobilities, and efficient solar to chemical energy conversion. However, due to chemical instability and the poor visible‐light utilization efficiency, individual phosphorus materials cannot promote charge transfer and separation. For designing active photocatalysts, phosphorus‐based hybrid materials with effective charge carriers separation at the heterojunction interface has played significant role. In this respect, considerable attempts have been made to fabricate black–red phosphorus heterostructure for photocatalytic applications and solar fuel generation, such as photocatalytic and electrocatalysis water splitting, CO2 reduction, carbohydrates synthesis, etc. This review article highlights the strategies for the synthesis of black–red phosphorus heterostructure materials for catalysis with a special focus on their potential for solar fuel generation applications. Recently developed black–red phosphorus heterostructure will be discussed, which can improve the most challenging drawback of phosphorus materials. Finally, the major challenges along with future trends of black–red phosphorus heterostructure in catalytic applications are outlined.This article is categorized under:

Lepton-flavor violating axions at MEG II
Authors: Jho Yongsoo , Knapen Simon , Redigolo Diego 
Published: October 2022

Abstract
We study the sensitivity of the existing MEG data to lepton flavor violating axion-like particles produced through μ+ → e+aγ and estimate the discovery potential for the upcoming MEG II experiment in this channel. The MEG II signal efficiency can be improved significantly if a new trigger can be implemented in a dedicated run with a reduced beam intensity. This search would establish the world leading measurement in this channel with only 1 month of data taking.
Global axisymmetric Euler flows with rotation
Authors: Guo Yan , Pausader Benoit , Widmayer Klaus 
Published: October 2022

AbstractWe construct a class of global, dynamical solutions to the 3d Euler equations near the stationary state given by uniform “rigid body” rotation. These solutions are axisymmetric, of Sobolev regularity, have non-vanishing swirl and scatter linearly, thanks to the dispersive effect induced by the rotation. To establish this, we introduce a framework that builds on the symmetries of the problem and precisely captures the anisotropic, dispersive mechanism due to rotation. This enables a fine analysis of the geometry of nonlinear interactions and allows us to propagate sharp decay bounds, which is crucial for the construction of global Euler flows.
Linear isoperimetric inequalities for free boundary submanifolds in a geodesic ball
Authors: Lee Eunjoo , Seo Keomkyo 
Published: October 2022

AbstractWe derive linear isoperimetric inequalities for free boundary submanifolds in a geodesic ball of a Riemannian manifold in terms of the modified volume. It is known that the twice of the area of a free boundary minimal surface in a Euclidean unit ball is equal to the length of its boundary. This can be extended to space forms by using our linear isoperimetric inequalities for the modified volume. Moreover, we obtain a sharp lower bound for the modified volume of free boundary minimal surfaces in a geodesic ball of the upper hemisphere $$\mathbb {S}_+^3$$

Cross domain fusion in power electronics dominated distribution grids
Authors: Sante Pugliese , Landsiedel Olaf , Kuprat Johannes , Liserre Marco 
Published: October 2022

AbstractIn the near future, a drastic change in the structure of the electric grid is expected due to the increasing penetration of power electronics interfaced renewable energy sources (e.g. solar and wind), highly variable loads (e.g. electric vehicles and air conditioning) and unexpected energy demanding events (e.g. pandemics or natural disasters). Energy balancing management, voltage and frequency stability, reduced system inertia, grid resilience to fault conditions, and power quality of the supply are a few of the main challenges in the future power electronics dominated grids. Power electronics can solve these by integrating information and communication technology in new intelligent, highly reliable, and efficient devices like smart transformers. Smart transformers can increase the power flow flexibility by enabling the correct meshed-hybrid grid operations, as long as load mission and power generation profiles are known. Those profile are generally driven by heterogeneous, highly sparse and often incomplete data that belong to different domains. This article highlights the necessity of new approaches and models to identify patterns and events of interest that can serve as a common base. The resulting patterns can then be cross-fused in a common language and form the basis of further data analytics in future distribution grids.

AbstractImmunohistochemistry is a powerful tool for studying neuronal tissue from humans at the molecular level. Obtaining fresh neuronal tissue from human organ donors is difficult and sometimes impossible. In anatomical body donations, neuronal tissue is dedicated to research purposes and because of its easier availability, it may be an alternative source for research. In this study, we harvested spinal cord from a single organ donor 2 h (h) postmortem and spinal cord from body donors 24, 48, and 72 h postmortem and tested how long after death, valid multi-color immunofluorescence or horseradish peroxidase (HRP) immunohistochemistry is possible. We used general and specific neuronal markers and glial markers for immunolabeling experiments. Here we showed that it is possible to visualize molecularly different neuronal elements with high precision in the body donor spinal cord 24 h postmortem and the quality of the image data was comparable to those from the fresh organ donor spinal cord. High-contrast multicolor images of the 24-h spinal cords allowed accurate automated quantification of different neuronal elements in the same sample. Although there was antibody-specific signal reduction over postmortem intervals, the signal quality for most antibodies was acceptable at 48 h but no longer at 72 h postmortem. In conclusion, our study has defined a postmortem time window of more than 24 h during which valid immunohistochemical information can be obtained from the body donor spinal cord. Due to the easier availability, neuronal tissue from body donors is an alternative source for basic and clinical research.
Caudodorsal approach combined with in situ split for laparoscopic right posterior sectionectomy
Authors: Yang Chongwei , Zhang Rixin , Zhu Ling , Zheng Xiaolin , Li Kai , Wang Pi-Xiao 
Published: October 2022

Abstract
Background
Laparoscopic right posterior sectionectomy (LRPS) was technically challenging and lack of standardization. There were some approaches for LRPS, such as caudal approach and dorsal approach. During our practice, we initiated pure LRPS using the caudodorsal approach with in situ split and present several advantages of this method.

Methods
From April 2018 to December 2021, consecutive patients who underwent pure LRPS using the caudodorsal approach with in situ split at our institution entered into this retrospective study. The key point of the caudodorsal approach was that the right hepatic vein was exposed from peripheral branches toward the root and the parenchyma was transected from the dorsal side to ventral side. Specially, the right perihepatic ligaments were not divided to keep the right liver in situ before parenchymal dissection for each case.

Results
11 patients underwent pure LRPS using the caudodorsal approach with in situ split. There were 9 hepatocellular carcinoma, 1 sarcomatoid hepatocellular carcinoma, and 1 hepatic hemangioma. Five patients had mild cirrhosis and 1 had moderate cirrhosis. All the procedures were successfully completed laparoscopically. The median operative time was 375 min (range of 290–505 min) and the median blood loss was 300 ml (range of 100–1000 ml). Five patients received perioperative blood transfusion, of which 1 patient received autologous blood transfusion and 2 patients received blood transfusion due to preoperative moderate anemia. No procedure was converted to open surgery. Two patients who suffered from postoperative complications, improved after conservative treatments. The median postoperative stay was 11 days (range of 7–25 days). No postoperative bleeding, hepatic failure, and mortality occurred.

Conclusion
The preliminary clinical effect of the caudodorsal approach with in situ split for LRPS was satisfactory. Our method was feasible and expected to provide ideas for the standardization of LRPS. Further researches are required due to some limitations of this study.
Inanspruchnahme der Notfallversorgung im Nordwesten Deutschlands
Authors: Seeger Insa , Thate Stefan , Ansmann Lena , Lubasch Johanna Sophie 
Published: October 2022

Zusammenfassung
Hintergrund
Mangelnde Kenntnisse über die Zuständigkeiten der Notfallversorgung führen zu einem höheren Bedarf an Ressourcen in der Notfallrettung. Die vorliegende Studie untersucht, ob sich die Inanspruchnahme und das Verhalten in Notfällen nach soziodemografischen Faktoren unterscheiden lassen.

Methodik
Von Januar bis Juli 2021 wurde eine anonyme schriftliche Befragung von über 4000 Besuchern des Oldenburger Impfzentrums durchgeführt. Der Fragebogen umfasste allgemeine Fragen zur Inanspruchnahme der Notfallversorgung sowie Fragen zur Selbsteinschätzung des eigenen Verhaltens in Notfällen und die Frage nach der Rufnummer des ärztlichen Bereitschaftsdiensts. Alter, Geschlecht und höchster Schulabschluss wurden ebenfalls erfasst. Sonderimpftage für medizinisch-pflegerisches Personal ermöglichten eine gesonderte Betrachtung der Stichprobe.

Ergebnisse
Weibliche Befragte hatten häufiger Kontakt zum ärztlichen Bereitschaftsdienst (19,6 % bzw. 15,6 %), jüngere Befragte suchten häufiger die Notaufnahme aus Eigeninitiative auf (72,1 % bzw. 13,2 %). Bei Schlaganfallsymptomen würden sich 10 % der Befragten mit höherem Schulabschluss und 25 % der Befragten mit niedrigem Schulabschluss zuerst an den Hausarzt wenden. Die Rufnummer des ärztlichen Bereitschaftsdiensts konnten 54,7 % des medizinisch-pflegerischen Personals korrekt wiedergeben. Im Notfall konnten sich 76,4 % aller Befragten eine erste ärztliche Beratung per Telefon oder Video vorstellen.

Diskussion
Soziodemografische Faktoren wirken sich auf die Nutzung der Ressourcen der Notfallrettung aus. Aufklärungsaktionen, frühzeitige Wissensvermittlung, ein gemeinsames Notfallleitsystem sowie eine telemedizinische Beratung bei niedrigschwelligen Einsätzen könnten zu einer Entlastung des Gesundheitssystems beitragen.
Couple stresses and discrete potentials in the vertex model of cellular monolayers
Authors: Jensen Oliver E. , Revell Christopher K. 
Published: October 2022

AbstractThe vertex model is widely used to simulate the mechanical properties of confluent epithelia and other multicellular tissues. This inherently discrete framework allows a Cauchy stress to be attributed to each cell, and its symmetric component has been widely reported, at least for planar monolayers. Here, we consider the stress attributed to the neighbourhood of each tricellular junction, evaluating in particular its leading-order antisymmetric component and the associated couple stresses, which characterise the degree to which individual cells experience (and resist) in-plane bending deformations. We develop discrete potential theory for localised monolayers having disordered internal structure and use this to derive the analogues of Airy and Mindlin stress functions. These scalar potentials typically have broad-banded spectra, highlighting the contributions of small-scale defects and boundary layers to global stress patterns. An affine approximation attributes couple stresses to pressure differences between cells sharing a trijunction, but simulations indicate an additional role for non-affine deformations.
Identifying digital capabilities in university courses: An automated machine learning approach
Authors: Fan Zongwen , Chiong Raymond 
Published: October 2022

AbstractDigital capabilities have become increasingly important in this digital age. Within a university setting, digital capability assessment is key to curriculum design and curriculum mapping, given that digital capabilities not only can help students engage and communicate with others but also succeed at work. To the best of our knowledge, however, no previous studies in the relevant literature have reported the assessment of digital capabilities in courses across a university. It is extremely challenging to do so manually, as thousands of courses offered by the university would have to be checked. In this study, we therefore use machine learning classifiers to automatically identify digital capabilities in courses based on real-world university course rubric data. Through text analysis of course rubrics produced by course academics, decision makers can identify the digital capabilities that are formally assessed in university courses. This, in turn, would enable them to design and map curriculums to develop the digital capabilities of staff and students. Comprehensive experimental results reveal that the machine learning models tested in this study can effectively identify digital capabilities. Among the prediction models included in our experiments, the performance of support vector machines was the best, achieving accuracy and F-measure scores of 0.8535 and 0.8338, respectively.
Cobots, “co-operation” and the replacement of human skill
Authors: Sorell Tom 
Published: October 2022

AbstractAutomation does not always replace human labour altogether: there is an intermediate stage of human co-existence with machines, including robots, in a production process. Cobots are robots designed to participate at close quarters with humans in such a process. I shall discuss the possible role of cobots in facilitating the eventual total elimination of human operators from production in which co-bots are initially involved. This issue is complicated by another: cobots are often introduced to workplaces with the message (from managers) that they will not replace human operators but will rather assist human operators and make their jobs more interesting and responsible. If, in the process of learning to assist human operators, robots acquire the skills of human operators, then the promise of avoiding replacement can turn out to be false, and if a human operator loses his job, he has been harmed twice over: once by unemployment and once by deception. I shall suggest that this moral risk attends some cobots more than others.

Abstract
Cerebral small vessel disease is a common neurological disease, and its incidence is increasing year by year worldwide. In recent years, research on cerebral small vessel disease has gained more and more attention. Our research aims to visualize publications to identify the hotspots and frontiers of cerebral small vessel disease research, and to provide reference and guidance for further research. Publications related to cerebral small vessel disease were searched from the Web of Science Core Collection and screened according to inclusion criteria. CiteSpace 5.8.R3 was used to evaluate and visualize results, including generating web maps and analyzing annual publications, countries, institutions, bibliographic and co-cited references, and keywords; in this article, we use CiteSpace and VOSviewer for the 2012 Cerebral small vessel disease and bibliometric analysis from January 1, 2022 to April 30, 2022. A total of 3037 papers related to cerebral small vessel disease were retrieved, and the number of published papers showed a steady upward trend. Among them, Neuroimaging standards for research into small vessel disease and its contribution to ageing and neurodegeneration, the most symbolic references in the field of cerebral small vessel disease have been cited a total of 438 times. Stroke is the most active journal (227 articles) and USA publishes up to 800 articles. Harvard Med SchUniv Edinburgh (133 papers) and Charidimou (85 papers) are the institutions and authors who have made the most contributions in this field, respectively. Among the keywords, most of them are related to the pathogenesis of cerebral small vessel disease. After 2018, gut-brain axis and cortex are the keywords with the strongest number of cited outbreaks. There is increasing evidence that cerebral small vessel disease is a research frontier and may remain a research hotspot in the future.
The Symbolic Life of Courts: How Judicial Language, Actions, and Objects Legitimize Credibility Assessments of Asylum Appeals
Authors: Johannesson Livia 
Published: October 2022

Abstract Asylum determinations are highly complex and difficult decisions. At the heart of this decision lies a credibility assessment of the asylum claimant’s narrative, which confronts the decision-maker with a seemingly straightforward question: do I believe this person’s story? To uphold legitimacy of this assessment, semi-legal criteria have been established internationally. However, these criteria have been criticized for relying on inaccurate and simplistic assumptions about human behavior, autobiographical memory, and communication. In light of this contestation, I ask how the legal-administrative practice of assessing credibility of asylum applications gains legitimacy in the eyes of the public, policy-makers, and legal professionals despite resting on highly disputable assumptions? To answer this question, I draw on interviews, observations, and written judgements from the Swedish administrative courts to explore how symbolic messages are tacitly conveyed through the use of judicial language, activities, and objects. The analysis suggests that cohesive, albeit tacit, messages about credibility assessments being accurate (rather than arbitrary), objective (rather than subjective), professional (rather than lay), and just (rather than unjust) are produced to both near and distant audiences. The study contributes to the literature on credibility assessments by offering a theoretical perspective that can unpack the relationship between symbolic communication in courts and perceived legitimacy for disputed practices within asylum determinations and migration control.
