Published: June 2023

AbstractAn increasing body of research indicates that annular stability plays a key role for a successful aortic valve repair. The aim of this study was to evaluate and compare a novel open aortic annuloplasty ring (the A-ring) with the Dacron ring. Both rings were compared with native aortic roots in vitro. Eighteen aortic roots were included in the study and randomized into three groups: the native, Dacron, and A-ring group. The roots were evaluated in an in vitro physiologic pulsatile model simulating the left side of the heart. Aortic annulus diameters were significantly reduced both in the Dacron ring group (p = 0.003) and the A-ring group (p = 0.020) when compared with the native group. Both the Dacron ring and A-ring effectively downsized the aortic annulus diameter. The A-ring also displayed an ability to maintain aortic root distensibility during the cardiac cycle equally to the Dacron ring.

Abstract
Turbines are core components in jet engines for flight propulsion, power plants, and other important energy conversion processes. They are composed of successive rows of blades so that wakes of upstream blades reach subsequent blades where they perturb the flow in an unsteady manner. At the point where a wake reaches the downstream blades, the perturbation forms a so-called negative jet. In this work, we show that the negative jet partially fulfills the conditions of an anti-splat. Based on this finding, we enhance an anti-splat detection algorithm developed by the present authors in previous work and apply it to direct numerical simulation data of a turbine cascade with unsteady wakes. This provides a sound framework and suitable visualization approaches to investigate the phenomenon even in very complex conditions, as is the alteration of the boundary layer flow along the pressure side of a turbine blade. The approach allows a very clear visualization of this interaction, which was not possible to evidence with previous methods, providing new insight into the physics of this flow. The use of flow paths shows up to which point wakes affect the boundary layer along the blade. The reported physical analysis, made possible by the proposed approach, demonstrates the usefulness of the method for the application domain. The generalization to flows in compressors, pumps, and blade-tower interaction in wind engineering and other fields is possible.

Published: June 2023

AbstractIn the last decade, conversational agents have been developed and adopted in several application domains, including education, healthcare, finance, and tourism. Nevertheless, chatbots still need to address several limitations and challenges, especially regarding personalization, limited knowledge-sharing capabilities, multi-domain campaign support, real-time monitoring, or integration of chatbot communities. To cope with these limitations, many approaches based on multi-agent systems models and technologies have been proposed in the literature, opening new research directions in this context. To better understand the current panorama of the different chatbot technology solutions employing agent-based methods, this Systematic Literature Review investigates the different application domains, end-users, requirements, objectives, technology readiness levels, designs, strengths, limitations, and future challenges of the solutions found in this scope. The results of this review are intended to provide researchers, software engineers, and innovators with a complete overview of the current state of the art and a discussion of the open challenges.

Published: June 2023

AbstractTwo novel compounds including a cyclohelminthol type polyketide (namely oxaleimide K, 1) and a maleimide derivative (namely peniroquefortine A, 2), and a new natural product (namely 2-(acetylamino)-N-[(1E)-2-phenylethenyl]-acetamide, 3), together with four known compounds (4–7), were isolated and identified from fungus Penicillium roqueforti, which was separated from the root soil of Hypericum beanii N. Robson collected from the Shennongjia Forestry District, Hubei Province. Their structures including absolute configurations were mainly established by the NMR spectroscopy analyses and single-crystal X-ray diffraction experiment. Compound 1 represents the second example of a cyclohelminthol type polyketide, which features a rare 6/6/5/5 tetracyclic system and a branched aliphatic chain containing a terminal olefin (oct-1-en-3-yl) moiety, and compound 2 possesses an unprecedented carbon skeleton that is uniquely defined by a maleimide moiety linked to the respective 4-methylene-2-(3-methylbut-2-en-1-yl)-phenol and para-substituted aromatic moieties via the carbon-carbon bonds. Remarkably, the absolute configuration of a cyclohelminthol type polyketide as exemplified by compound 1 is determined by the single-crystal diffraction analysis for the first time, highlighting an E-configuration for the linkage of a succinimide moiety and a tetrahydrofuran moiety for 1 rather than a Z-configuration as previously reported in the biosynthesis study, which gives a new insight into the structural elucidation of this category of polyketides. Additionally, compound 1 exhibited significant cytotoxic activity against multiple tumor cells, especially against the Farage and SU-DHL-2 cells (IC50 < 20 µM, 48 h). Further mechanism study revealed that compound 1 significantly induced cell cycle arrest in Farage and SU-DHL-2 cells by causing abnormal ROS level and triggering oxidative stress.

Delusions as Storytelling Gone Wrong in Bad Life Situations: Exploring a Discursive Contextual Analysis of Delusions with Clinical Implications
Authors: Guerin Bernard 
Published: June 2023

Abstract
A contextual model of delusions drawing on discourse analysis is explored, which changes current attributional models to more concrete and observable forms of language-in-context. Most current models view delusions as internal beliefs that are the result of faulty reasoning or cognitive errors, whereas the present model treats delusions as natural discourses that have gone wrong or become exaggerated as strategies shaped by the person’s bad life situations and negative social relationships. Brief reviews are made of the properties attributed to delusional beliefs (Table 1) and of the current explanations for delusions (Table 2). An outline of a discursive contextual analysis is then given along with a review of the life contexts for those with “mental health” issues. Discourse analysis is used to account for the delusional properties as discursive properties (Table 3). Delusions are then analyzed in two ways as normal discourse strategies gone wrong when trying to live in bad life contexts: (1) by analyzing “beliefs” as a way of doing social behavior with language; and (2) by analyzing delusions as normal storytelling gone wrong from being shaped by bad social relationships. Table 5 gives some practical questions for therapists and researchers to explore people’s delusions as discursive strategies.
Experimental study of shear behavior of rock–shotcrete interface under dynamic shearing: insights from interface roughness and strain rate

Published: June 2023

AbstractRock–shotcrete structures are often suffered from dynamic shearing. However, the understanding of the dynamic shear response of rock–shotcrete structures is still at its infancy. To investigate the effects of strain rate and interface roughness on the dynamic shear response of rock–shotcrete structure, laboratory tests were carried out on the modified double notched sandstone–concrete specimen. Testing results show that the dynamic shear strength and dynamic peak strain of sandstone–concrete specimens are both far less than those of sandstone and concrete specimens. With increasing strain rate, the dynamic shear strength of sandstone–concrete specimen increases and the failure mode changes from interfacial shear failure to the mixed failure, i.e., the interfacial, concrete and sandstone shear failure. With the increase in interface roughness, the failure mode changes from sliding fracture to shear-off fracture, leading to an increase in dynamic shear strength and shear peak strain of sandstone–concrete specimens. In addition, it is the smallest sawtooth angle at the sandstone–concrete interface that dominates the dynamic shear strength of sandstone–concrete specimens. The findings in the present study could facilitate understanding the shear behavior and failure mechanism of the rock–shotcrete structure subjected to dynamic loading and be helpful in the efficient design, reinforcement and stability of rock–shotcrete engineering.
Geschichtlichkeit und ästhetische Relevanz
Authors: Mehltretter Florian 
Published: June 2023

ZusammenfassungVor dem Hintergrund einer breiten Diskussion über das Verhältnis zwischen literarhistorischer Erforschung und ästhetischer Würdigung historisch ferner Literatur im ersten Jahrzehnt der DVjs legt Erich Auerbach eine Lektüre von Dantes Commedia vor, die beides verbindet. In seinem Artikel »Entdeckung Dantes in der Romantik« in der DVjs von 1929 zeigt er, dass er diesen (im gleichen Jahr in dem Buch Dante als Dichter der irdischen Welt weiter ausgestalteten) Ansatz wesentlich aus Überlegungen Schellings und Hegels entwickelt hat, von denen er auch gewisse metaphysische Hypotheken übernimmt. Die darin liegende besondere Auffassung von Realismus (die 1946 in Auerbachs Buch Mimesis ausgefaltet wird) spitzt er in dem Aufsatz »Figura« von 1939 für seine Danteinterpretation unter Verwendung des bibelhermeneutischen Konzepts der Figuraltypologie zu, allerdings um den Preis einer gewissen Entstellung der historischen Tradition der Typologie. Dadurch gewinnt Auerbach der Literaturwissenschaft ein machtvolles Begriffsinstrument hinzu, das in den dann folgenden Generationen unter Hinweis auf die Polysemie des lateinischen Ausdrucks figura teils unspezifisch eingesetzt wird, nun nicht mehr einer Vorstellung von Literatur als Mimesis, sondern als Ort von Vieldeutigkeit schlechthin folgend.
School Bullying and Personality Traits from Elementary School to University
Authors: Gkatsa Tatiani 
Published: June 2023

AbstractThis retrospective study examines involvement in school bullying at all developmental stages, from elementary school to university, in relation to personality traits. Participants were 216 university students, 162 (75.0%) females and 54 (25.0%) males. The majority of the sample (88.9%) aged 18–24. Students completed the International Personality Items Pool (BFFM) and a self-report questionnaire about school bullying online. The results show that the involvement roles in personality trait A3 (don’t insult) of the Agreeableness (A) scale differ significantly at all educational levels. However, trait E6 Extraversion (E) and the Conscientiousness (C) scale differ at the elementary school level, and trait N6 of the Neuroticism (N) scale varies at the middle school and N3 differs at the high school. All participants differ statistically significantly in A3, Conscientiousness scale at all educational levels. Those involved differ statistically significantly in the traits Neuroticism, C8, and C9 and in two traits of Openness (O). Throughout the course of schooling, victims showed a higher score on the Conscientiousness scale than the bullies/victims. The victims who became the bullies (victims/bullies) had a higher score on the Emotional Stability scale than the bullies who became victims (bullies/victims). About half of the participants said that the experience affected them positively and the other half negatively. Those who answered that it had a positive impact on them showed a statistically significant difference in characteristics E7 (talkativeness) and N10 (pleasant mood). The findings help inform a new perspective of anti-bullying intervention that targets personality traits in all the roles and their rotation.

AbstractLeigh syndrome (LS) or subacute necrotizing encephalomyelopathy is a progressive, lethal, mitochondrial disease mostly presenting in childhood. We report a 36-year-old African male presenting to the Emergency Department with a 6-month history of progressive dysarthria. Examination also showed oculomotor limitations for downgaze and convergence, mild right hemiparesis with Babinski sign, and absent lower limb tendon reflexes. He revealed he was presenting mild walking difficulties since the age of 25. Family history was unremarkable. A brain magnetic resonance showed diffuse white matter lesions without enhancing around the third ventricle, in the medulla oblongata, and bilaterally to the caudate and the putamen. Polymerase-chain-reaction amplification of the mitochondrial genes, followed by direct sequencing, found a 10191T>C variant related to LS. To now, only 8 late-onset patients share the same pathogenic variant.
Livestock hauler and dairy farmer perspectives about cull dairy cattle transport and cattle transport regulations in British Columbia, Canada
Authors: Kuo Christine , von Keyserlingk Marina AG 
Published: June 2023

Abstract
Dairy cows are usually culled and transported from the farm when they no longer meet the farm’s standards for production or are not needed for milk production. Some cows are transported while in poor condition and may deteriorate further during transport. In February 2020, Canadian federal animal transport regulations were revised with the aim to minimise risks to livestock during transport; changes that may impact cull dairy cows included defining compromised cattle and limiting their maximum transport time. This study conducted semi-structured interviews with dairy farmers (n = 6) and cattle haulers (n = 4) in British Columbia, Canada, to gain an in-depth understanding of the effect of the regulations on their practices when shipping and transporting dairy cows to slaughter. Interviews were transcribed in Otter.ai and thematically coded in NVivo 12. While farmer and hauler participants recognised the importance of animal welfare during transport and described practices such as shipping mobile animals to reduce the risk that cows would become non-ambulatory during transport, they also described little change in shipping and transport practices due to the new regulations. Among interviewed participants, barriers to compliance with the regulations appear to be low knowledge of, and mixed or negative attitudes towards the regulations. Participants also described how they felt a lack of communication along the transport chain and limited transport and slaughter infrastructure made compliance difficult. Possible suggestions to remedy these barriers include providing educational resources about the regulations and encouraging communication about cow fitness for transport between responsible parties in the transport chain.

AbstractIn a survey of infection prevention programs, leaders reported frequent clinical and infection prevention practice modifications to avoid coronavirus disease 2019 (COVID-19) exposure that exceeded national guidance. Future pandemic responses should emphasize balanced approaches to precautions, prioritize educational campaigns to manage safety concerns, and generate an evidence-base that can guide appropriate infection prevention practices.
Librarians as Agents of German Foreign Policy and the Cultural Consequences of the First World War
Authors: Gusejnova Dina 
Published: June 2023

AbstractIn this article I explore the cultural impact of the First World War by analysing the work of libraries and librarians in different settings, from German-occupied Belgium and prisoner-of-war camps to Germany's own public and private libraries. By examining the work of German, Russian, Polish, Ukrainian, and American librarians, the article makes a case for applying the notion of a ‘long’ First World War to cultural and intellectual history. Considering ephemeral and established libraries, along with new types of collections generated by the war itself, the article sheds light on the changes to library work as a result of mobilization, censorship, and the growth of mass readership. While these changes concerned librarians in all belligerent states, German librarians were particularly affected after the burning of the Leuven library during the city's occupation by German forces. This singular event damaged Germany's national reputation and thereby laid the groundwork for a significant politicization of library work all the way to the Second World War. In addition to tracing the importance of librarians for German foreign policy, the article reconstructs how this professional community, whose intellectual formation was ultimately supranational, responded to the First World War.
Writing in Roman Britain and Continental Europe: A Comparative Analysis of Styli Found in London
Authors: Colombo Alessia 
Published: June 2023

AbstractThis paper investigates Roman writing habits through the evidence of metal styli. An assemblage of more than 400 styli from London constitutes the basis of the analysis, which explores their similarities with examples from other sites in Britain and continental Europe during the Imperial period. The geographical and social distribution of styli suggests that certain types were employed or made in specific locations by different social actors, and that the major political and military centres of the Empire shared a common material culture of writing. The analysis also suggests that styli types of the northern European regions possibly developed from ‘military styli’ brought by soldiers and bureaucrats during the conquest.

Abstract
The recent reinforcement of CoV surveillance in animals fuelled by the COVID-19 pandemic provided increasing evidence that mammals other than bats might hide further diversity and play critical roles in human infectious diseases. This work describes the results of a two-year survey carried out in Italy with the double objective of uncovering CoV diversity associated with wildlife and of excluding the establishment of a reservoir for SARS-CoV-2 in particularly susceptible or exposed species. The survey targeted hosts from five different orders and was harmonised across the country in terms of sample size, target tissues, and molecular test. Results showed the circulation of 8 CoV species in 13 hosts out of the 42 screened. Coronaviruses were either typical of the host species/genus or normally associated with their domestic counterpart. Two novel viruses likely belonging to a novel CoV genus were found in mustelids. All samples were negative for SARS-CoV-2, with minimum detectable prevalence ranging between 0.49% and 4.78% in the 13 species reaching our threshold sample size of 59 individuals. Considering that within-species transmission in white-tailed deer resulted in raising the prevalence from 5% to 81% within a few months, this result would exclude a sustained cycle after spillback in the tested species.
Modelling the impact of COVID-19 and routine MenACWY vaccination on meningococcal carriage and disease in the UK

Published: June 2023

Abstract
Country-wide social distancing and suspension of non-emergency medical care due to the COVID-19 pandemic will undoubtedly have affected public health in multiple ways. While non-pharmaceutical interventions are expected to reduce the transmission of several infectious diseases, severe disruptions to healthcare systems have hampered diagnosis, treatment, and routine vaccination. We examined the effect of this disruption on meningococcal disease and vaccination in the UK. By adapting an existing mathematical model for meningococcal carriage, we addressed the following questions: What is the predicted impact of the existing MenACWY adolescent vaccination programme? What effect might social distancing and reduced vaccine uptake both have on future epidemiology? Will catch-up vaccination campaigns be necessary? Our model indicated that the MenACWY vaccine programme was generating substantial indirect protection and suppressing transmission by 2020. COVID-19 social distancing is expected to have accelerated this decline, causing significant long-lasting reductions in both carriage prevalence of meningococcal A/C/W/Y strains and incidence of invasive meningococcal disease. In all scenarios modelled, pandemic social mixing effects outweighed potential reductions in vaccine uptake, causing an overall decline in carriage prevalence from 2020 for at least 5 years. Model outputs show strong consistency with recently published case data for England.
