Authors: Wei Qiyi , Li Liang , Deng Zhen , Wan Gengping , Zhang Ying , Du Changlong , Su Yanran , Wang Guizhen 
Published: April 2023

AbstractIn this work, inspired by the great advantage of the unique “brick‐mortar” layered structure as electromagnetic interference (EMI) shielding materials, a multifunctional flexible graphene nanosheets (GNS)/polytetrafluoroethylene (PTFE) composite film with excellent EMI shielding effects, impressive Joule heating performance, and light‐to‐heat conversion efficiency is fabricated based on the self‐emulsifying process of PTFE. Both PTFE microspheres and nanofibers are employed together for the first time as “sand and cement” to build unique nacre‐structured EMI shielding materials. Such configuration can obviously enhance the adhesion of composites and improve their mechanical property for the application under extreme environment. Moreover, the simple and effective repetitive roll pressing method can be used for the scalable production in industrialization. The GNS/PTFE composite film shows a high EMI shielding effectiveness (SE) of 50.85 dB. Furthermore, it has a high thermal conductivity of 16.54 W (m K)−1, good flexibility, and recyclable properties. The excellent fire‐resistant and hydrophobic properties of GNS/PTFE film also ensure its reliability and safety in practical application. In conclusion, the GNS/PTFE film demonstrates the potential for industrial manufacturing, and outstanding EMI shielding performance with high stability and durability, which has a broad application prospect for electronic devices in practical extreme outdoor environments.
Approach to assessment of existing structures in the fib Model Code 2020
Authors: Walraven Joost , Dieteren Gerrie 
Published: April 2023

AbstractExisting structures often no longer meet the demands formulated in contemporary design codes with respect to structural safety and serviceability. This occurs, for instance, if the loads on existing structures, like traffic loads on bridges, are larger than assumed in the original design. A second potential reason is that structures are subject to deterioration, like alkali–silica reaction within the concrete or corrosion of the reinforcement due to chloride attack or carbonation. A third possible reason is that in recent codes, additional criteria have been introduced based on new theories and/or negative experiences with older structures. The new fib Model Code for Concrete Structures 2020 will be valid both for the design of new structures and the assessment of existing structures. This paper shows how the design and assessment of concrete structures are integrated into this new code concept.
First‐Principles Calculations for the Enhancement of Mechanical Properties of High‐Entropy Alloys by Carbon Elements
Authors: Ding Can , Feng Lu , Yuan Zhao 
Published: April 2023

AbstractA series of alloy solid solution models were developed using the SQS modeling method, and the effect of C doping on the phase structure, elastic properties, and electronic structure of the alloys was investigated using a first‐principles approach. The results showed that the CuCrWNi (C), CuCrWMo (C), and CuCrWAl (C) alloys all have a single body‐centered cubic (BCC) structure. The alloys conformed to the mechanical stability criterion before and after incorporating C. The incorporation of C leads to an increase in the bulk modulus B of the CuCrWNi, CuCrWAl alloy, and the Young's modulus E and shear modulus G of the CuCrWMo, CuCrWAl alloy. In comparison, the shear modulus G and Young's modulus E of CuCrWNi alloy and the bulk modulus B of CuCrWMo alloy show a decreasing tendency. The alloy is ductile before and after the addition of C. The addition of C increased the Poisson's ratio, Pugh ratio, and Cauchy pressure of CuCrWNi alloy and decreased the Poisson's ratio, Pugh ratio, and Cauchy pressure of CuCrWMo and CuCrWAl. This shows that adding C improves the ductility of CuCrWNi and the strength of CuCrWMo and CuCrWAl alloys. By analyzing the electronic structure of the alloys, it was found that the doping of C made the alloy less stable. Adding C makes the high‐entropy alloys more conducive and the metallic properties more noticeable. Moreover, the incorporation of C makes the CuCrWNi pseudo‐energy gap decrease and the CuCrWMo, and CuCrWAl pseudo‐energy gap increase, which may be related to the change in the mechanical properties of the alloy. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

AbstractMany companies in the Industry 4.0 (I4.0) environment are still lacking knowledge and experience of how to enter and participate in a platform-based ecosystem to gain long-term competitive advantages. This leads to uncertainty among firms when transforming into platform-based ecosystems. The article presents a structuralist approach to conceptualize the platform-based ecosystem construct, giving an overview of the literature landscape in a model bundled with unified terminology and different perspectives. The holistic process model aggregates the findings of 130 papers regarding platform-based ecosystem literature. It consists of 4 phases and 16 design elements that unify different terminologies from various research disciplines in one framework and provide a structured and process-oriented approach. Besides, use cases for different design elements were developed to make the model apply in an I4.0 context. Use Case I is a methodology that can be used to model and validate usage hypotheses based on usage data to derive optimization potential from identified deviations from real product usage. By collecting and refining data for analyzing different manufacturing applications and machine tool behavior the importance of specific data is shown in Use Case II and it is highlighted which data can be shared from an external perspective. Use Case III deals with strategic modeling of platform-based ecosystems and the research identifies control points that platform players can actively set to adjust their business models within alliance-driven cooperation to create and capture value jointly. Use Case IV investigates the status quo and expectations regarding platform-based ecosystems in the field of laser technology with the help of structured expert interviews. Overall, this chapter presents a framework on industrial platform-based ecosystems that gives researchers and practitioners a tool and specific examples to get started in this emerging topic.

On the cost of the bubble set for random interlacements
Authors: Sznitman Alain-Sol 
Published: April 2023

AbstractThe main focus of this article concerns the strongly percolative regime of the vacant set of random interlacements on${\mathbb{Z}}^{d}$Zd,$d \ge 3$d≥3. We investigate the occurrence in a large box of an excessive fraction of sites that get disconnected by the interlacements from the boundary of a concentric box of double size. The results significantly improve our findings in Sznitman (Probab. Math. Phys. 2–3:563–311, 2021). In particular, if, as expected, the critical levels for percolation and for strong percolation of the vacant set of random interlacements coincide, the asymptotic upper bound that we derive here matches in principal order a previously known lower bound. A challenging difficulty revolves around the possible occurrence of droplets that could get secluded by the random interlacements and thus contribute to the excess of disconnected sites, somewhat in the spirit of the Wulff droplets for Bernoulli percolation or for the Ising model. This feature is reflected in the present context by the so-calledbubble set, a possibly quite irregular random set. A pivotal progress in this work has to do with the improved construction of a coarse grained random set accounting for the cost of the bubble set. This construction heavily draws both on themethod of enlargement of obstaclesoriginally developed in the mid-nineties in the context of Brownian motion in a Poissonian potential in Sznitman (Ann. Probab. 25(3):1180–1209, 1997; Brownian Motion, Obstacles and Random Media. Springer, Berlin, 1998), and on theresonance setsrecently introduced by Nitzschner and Sznitman in (J. Eur. Math. Soc. 22(8):2629–2672, 2020) and further developed in a discrete set-up by Chiarini and Nitzschner in (Commun. Math. Phys. 386(3):1685–1745, 2021).
OptiScreen – ein Schulungskonzept für Pflegekräfte zur Durchführung des psychosozialen Distress-Screenings
Authors: Dreismann L. , Wenzel M. , Ginger V. , Zimmermann T. 
Published: April 2023

Zusammenfassung
Hintergrund
Eine angemessene, bedarfsgerechte psychoonkologische Versorgung reduziert Depressivität und Ängste von Krebserkrankten sowie ihren Angehörigen und erhöht die Lebensqualität. Psychisch belastete Krebserkrankte werden jedoch nicht flächendeckend identifiziert, um ihnen psychoonkologische Unterstützung anzubieten. Screeningfragebögen haben sich zur Identifikation bewährt, allerdings bestehen bei der Anwendung im klinischen Alltag Hürden. Pflegekräfte haben durch ihren kontinuierlichen Kontakt zu Patient_innen, die vielfältigen klinischen Eindrücke und ihre Verbindung zu anderen Berufsgruppen eine Schlüsselrolle.

Ziele
Die OptiScreen-Schulung soll Pflegekräfte in der Onkologie zur Durchführung des Distress-Screenings befähigen, entsprechendes Expert_innenwissen vermitteln und Hürden sowie Unsicherheiten im Screeningprozess abbauen, um somit belastete Erkrankte zielgerichtet identifizieren und einer psychoonkologischen Versorgung zuführen zu können.

Das Training
Die OptiScreen-Schulung gliedert sich in drei Module à 1,5–2 h zu den Themen psychische Störungen bei Krebs, psychoonkologische Versorgung, psychische Belastung, Distress-Screening, Kommunikation im Screeningprozess und Psychohygiene (vermittelt durch Vorträge, Videos, Rollenspiele, Übungen).

Ergebnisse und Diskussion
Erste praktische Erfahrungen weisen auf eine erfolgreiche Umsetzung des Schulungskonzepts hin. Weitere Ziele sind es, den Wissenszuwachs und die zunehmende Sicherheit der Pflegekräfte im Screeningprozess zu stärken sowie die Effekte langfristig aufrechtzuerhalten. Zusätzlich soll die Schulung in verschiedenen Settings etabliert und die Auswirkungen der Schulung in Bezug auf die Informiertheit und Zufriedenheit der Patient_innen mit dem Screeningprozess untersucht werden.
Successful use of extracorporeal life support and hemadsorption in the context of venlafaxine intoxication requiring cardiopulmonary resuscitation: a case report
Authors: Hoffmann Matthias , Akbas Samira , Kindler Rahel , Bettex Dominique 
Published: April 2023

AbstractVenlafaxine is a serotonin and noradrenalin reuptake inhibitor prescribed as an antidepressant. Overdose clinically manifests with neurological, cardiovascular and gastrointestinal abnormalities based on, amongst others, serotonin syndrome and can be life-threatening due to cardiovascular collapse. Besides immediate decontamination via gastric lavage and inhibition of enteral absorption through active charcoal, successful hemadsorption with CytoSorb® has been reported. We present the case of a 17-year-old female who required extracorporeal life support (ECLS) for cardiovascular collapse as a result of life-threatening venlafaxine intoxication. Serial serum blood concentrations of venlafaxine/desmethylvenlafaxine on admission at a tertiary hospital (approx. 24 h after ingestion) and subsequently 6 h and 18 h thereafter, as well as on days 2 and 4, were measured. CytoSorb® was initiated 6 h after admission and changed three times over 72 h. The initial blood concentration of venlafaxine/desmethylvenlafaxine was 53.52 µmol/l. After 6 h, it declined to 30.7 µmol/l and CytoSorb® was initiated at this point. After 12 h of hemadsorption, the blood level decreased to 9.6 µmol/l. On day 2, it was down to 7.17 µmol/l and decreased further to 3.74 µmol/l. Additional continuous renal replacement therapy using CVVHD was implemented on day 5. The combination of hemadsorption, besides traditional decontamination strategies along maximal organ supportive therapy with ECLS, resulted in the intact neurological survival of the highest venlafaxine intoxication reported in the literature to date. Hemadsorption with CytoSorb® might help to reduce blood serum levels of venlafaxine. Swift clearance of toxic blood levels may support cardiovascular recovery after life-threatening intoxications.

AbstractShipping is the backbone of international trade and oil companies want their oil tankers to arrive safely. The safety and security of international shipping of crucial elements such as oil has always been important aspect in the landscape of piracy. The implications of piracy attacks are linked with loss of cargo or personnel, economic and environmental catastrophe. Despite maritime piracy being a major concern to international trade, no comprehensive study considers the causing factors and spatio-temporal patterns that influence the choice of attack areas. Thus, this research expands our understanding on the areas where piracy mainly occurs, and its underlying causes. To achieve these objectives, AHP and spatio-temporal analysis applied by using data from the National Geospatial-Intelligence Agency. The results indicate that territorial waters are preferable areas; thus, pirates prefer to attack the ships close to the coastline fewer times near ports, and rarely in international waters. This is in line with the spatio-temporal analysis results that show that pirates except for the Arabian sea prefer to hit close to the coastline of countries that face political instability, lack of properly functioning government and extreme poverty. Moreover, pirates in certain areas are influenced by the activity and the information from other pirates, which can be used as tool from the authorities e.g., derive information from pirates that have been arrested. Overall, this study contributes on the literature of maritime piracy, and it could be used to enhance security and build tailored defense strategies in perilous water areas.

Published: April 2023

AbstractDuring the last decade an eruptive increase in the demand for intelligent m-learning environments has been observed since instructors in the online academic procedures need to ensure reliability. The research for decision systems seemed inevitable for flexible and effective learning in all levels of education. The prediction of the performance of students during their final exams is considered as a difficult task. In this paper, an application is presented, contributing to an accurate prediction which would assist educators and learning experts in the extraction of useful knowledge for designing learning interventions with enhanced outcomes.
Approaches for reducing the iodine content of the brown seaweed Saccharina latissima—effects on sensory properties

Published: April 2023

AbstractThe effects of steam- or warm water treatments of the brown seaweed Saccharina latissima on iodine content and nutrient and sensory profiles were investigated. Warm freshwater or seawater treatments reduced the dry weight iodine content by 73% and 59%, respectively. Steam treatment was less efficient and only reduced the iodine content by 26%. Freshwater treatment resulted in a greater reduction in total solids and loss of water-soluble components, mainly reducing the content of ash and carbohydrates. Seawater treatment had a small effect on total solid content but altered the mineral profile leading to an increase in sodium and decrease in potassium content. The sensory profiles reflected the observed differences in composition as it revealed a significantly higher saltiness of the seawater-treated sample compared to other treatments, as well as a higher umami intensity compared to the freshwater-treated sample. The latter was characterized by low scores across all sensory attributes, indicating greater loss of flavour-active compounds. Further, including seawater-treated S. latissima at relatively low levels (0.5% and 1%) significantly altered the flavour of a commercial spinach soup compared to the same preparation without seaweed. Therefore, warm water treatment using seawater could be an alternative method for lowering the iodine content in brown seaweed while limiting nutrient loss and maintaining its flavour potential for applications in the food industry.

Published: April 2023

AbstractHigh implant survival rates have been achieved in recent decades due to continual modifications in implant design and surface topography, however there is still an ongoing quest to control peri-implant bone loss. The objective of this work was to develop Ti-35Nb-7Zr-5Ta (TNZT) alloys, perform physicochemical and morphological characterization of their surface modified by electrolytic oxidative plasma technique with ions related to osseointegration and lastly evaluate bacterial colonization in vitro. Three groups were evaluated: C group (polished TNZT), CaP group (sodium β glycerophosphate + calcium acetate) and Mg group (magnesium acetate). Before and after anodizing the surfaces, physicochemical and morphological analyses were performed: scanning electron microscopy with field emission gun (FEG-SEM), energy dispersion spectroscopy (EDS), X-ray diffraction (DRX), wettability (goniometer) and roughness (rugometer). Controlled and treated specimens were contaminated with unstimulated saliva collected from 10 healthy volunteers. Then, biofilm samples were collected and up to 35 microbial species, including commensal and pathogenic microorganisms, were identified and quantified by the Checkerboard DNA-DNA Hybridization method. The CaP group modified the surface morphology in the form of pores, while the Mg group modified it in the form of flakes. The contact angle was significantly smaller in the CaP group. The average roughness was higher in the CaP and Mg groups. A smaller total amount of bacteria was identified in the Mg group and relevant differences were found in the microbial profile associated with different surface treatments. Therefore, considering the microbiological profile and for the prevention of peri-implantitis, the Mg group presented more satisfactory and encouraging results for the manufacture of dental implants

Three Contrasting Accounts of Electronic Gambling Machine Related Harm: Impacts on Community Views Towards Gambling Policy and Responsibility
Authors: Myles Dan , O’Brien Kerry , Yücel Murat , Carter Adrian 
Published: April 2023

AbstractThis study investigated whether there was community support for prominent gambling harm reduction policies, as well as perceived responsibility for electronic gambling machine (EGM) related harm in an Australian sample (n = 906). Using a randomised experimental design, we also explored whether these outcomes were influenced by three alternative explanations for EGM-related harm: a brain-based account of gambling addiction, an account that highlighted the intentional design of the gambling environment focused on the “losses disguised as wins” (LDWs), and a media release advocating against further government intervention in the gambling sector. We observed clear majority support for most policies presented, including mandatory pre-commitment, self-exclusion, and a $1 limit on EGM bets. A substantial majority of participants agreed that individuals, governments, and industry should be held responsible for EGM-related harm. Participants presented with the explanation of LDWs attributed greater responsibility for gambling-related harm to industry and government, less agreement that electronic gambling machines are fair, and more agreement that EGMs are likely to mislead or deceive consumers. There was some limited evidence of greater support for policy intervention in this group, including a blanket ban of EGMs, clinical treatment funded by gambling taxes, mass media campaigns, and mandatory pre-commitment for EGMs. We found no evidence that a brain-based account of gambling addiction substantially undermined support for policy intervention. We predicted that the information about LDWs and the brain-based account of EGM related harm would soften attributions of personal responsibility for gambling harm. Our results did not support either of these predictions.
