Authors: Zhao Yali , Hou Yahui , Xu Zhiyuan , Chang Shuai , Gou Xiaofeng , Zhao Junlong 
Published: April 2022

AbstractIn order to improve the catalytic performance, oxidation resistance and thermal stability of neutral alkyl ferrocene‐based combustion rate catalysts, mononuclear ferrocene energetic compounds were designed and prepared, but four binuclear ferrocene energetic compounds were unexpectedly discovered during the synthesis compounds. The new compounds were characterized by single‐crystal X‐ray diffraction,1H and13C nuclear magnetic resonance spectroscopy, and high‐resolution mass spectrometry. The crystal structures of compoundsa,b,canddconfirmed that we have successfully prepared binuclear ferrocene nitrogen‐containing heterocyclic compounds. The thermogravimetric results revealed that most of the compounds exhibit high thermal stability. The electrochemical properties of the four compounds were examined by cyclic voltammetry (CV) and differential pulse voltammetry; the CV experimental results indicated that these compounds showed good electrochemical performance, which contributed to their burning rate catalytic activity in composite solid propellants. Differential scanning calorimetry was used to study the catalytic performance of the binuclear ferrocene energetic compounds for ammonium perchlorate (AP). The results show that these compounds have a good combustion catalytic effect on AP due to the increase in the number of ferrocene groups.
Printers, Publishers, and Sellers: Actors in the Process of Consolidation of Epistemic Communities in the Early Modern Academic World
Authors: Valleriani Matteo , Ottone Andrea 
Published: April 2022

AbstractThis chapter proposes a global view of the set of dynamics of interplay that were generated in the early modern publishing sector around a single astronomical work, the Tractatus de sphaera by Johannes de Sacrobosco. The Sphaera, a thirteenth-century tract of geocentric cosmology, rather than remaining a static text, became over the centuries a multiauthored dynamic textual tradition. This essay argues that publishers, printers, and booksellers had a fair share of agency not only in perpetuating but also in shaping the evolution of this long-lasting textual tradition. The present essay traces the ways this agency was configured.
Paratexts, Printers, and Publishers: Book Production in Social Context
Authors: Valleriani Matteo , Sander Christoph 
Published: April 2022

AbstractParatexts, such as dedication letters or epigrams, in early modern printed books can be used by historians to situate a book’s production in its institutional and social context. We depart from the general assumption that two publishers or printers were in a relation of awareness of each other if they printed and put on the market two different editions that contain at least one identical paratext. In this paper, we analyze the circulation of the paratexts among the 359 editions of the “Sphaeracorpus.” First, we discuss the available data, the conditions to build a social network, and the latter’s characteristics. Second, we interpret the results—potential relationships among printers and publishers—from a historical point of view and, at the same time, discuss the sorts of potential relationships that this method can disclose. Third, we corroborate the historical results among different approaches, namely by using editions’ fingerprints and by investigating the book production of those printers and publishers tangentially involved in relevant relationships, but who fall outside the “Sphaeracorpus.” Finally, we identify local communities of printers and publishers and, on a transregional level, printers, and publishers who were observing and influencing each other.
Printing Sacrobosco in Leipzig, 1488–ca. 1521: Local Markets and University Publishing
Authors: Kremer Richard L. 
Published: April 2022

AbstractDuring the first fifty years of its printing, the greatest number of Sacrobosco Sphaera editions appeared in Venice, Paris, and Leipzig. Indirect evidence suggests that the Venetian and Parisian copies circulated widely; Leipzig editions, however, primarily served the local market, i.e., university students in Leipzig, Erfurt, and Wittenberg. This paper analyzes fifteen editions of Sacrobosco’s Sphaera issued by three Leipzig printers between 1488 and ca. 1521. These Leipzig Sacroboscos share a common text, set of woodcuts, and mis-en-page that were not much copied by printers beyond Leipzig. The paper also investigates the Leipzig masters who lectured on Sacrobosco during these decades; several became known locally as mathematicians, but most moved to other faculties or left the university. Three of the masters authored commentaries that printers added to their editions. One of these borrowed heavily from a lengthy commentary by the Paduan master, Francesco Capuano, printed 1499 in Venice. Another commentary would be reprinted several times in Cologne, but generally the Leipzig commentaries also remained local in their influence. After Wittenberg printers began issuing Sacroboscos in 1531, no further editions would be printed in Leipzig. The Leipzig Sacroboscos thus illustrate the dynamics of a local university market shaping the early printing history of this introductory textbook.
Erhard Ratdolt’s Edition of Sacrobosco’s Tractatus de sphaera: A New Editorial Model in Venice?
Authors: Rideau-Kikuchi Catherine 
Published: April 2022

AbstractThe aim of this paper is to investigate the construction process of Sacrobosco’sTractatusas a successful venture in the early publishing market and the seminal role of some of its editions. Venice is a good case study since Venetian printers regularly printed the early editions of theSphaeraand fashioned the way the text was laid in print. In 1478, in the context of aggressive competition with Erhard Ratdolt, Franz Renner chose a traditional conceptual approach to the text and printed it in a new formal adaptation. Ratdolt responded by emphasizing the importance of the illustrations and by printing Sacrobosco’s treatise with other texts from contemporary scholars Georg Peuerbach and Regiomontanus. His editions could be found across Europe. His choices also inserted Sacrobosco’s thirteenth-century treatise into contemporary academic debates. Finally, Ratdolt’s edition set a formal standard, completed with Santritter’s 1488 edition, and copied in Venice and across Europe. In the following years, many Venetian printers copied the publishing solution developed by Ratdolt and fully realized it in Johann Lucilius Santritter’s 1488 edition in an environment of harsh competition. However, other models were developed and coexisted in Venice, probably targeting different audiences and different reading practices.
Mathematical Books in Paris (1531–1563): The Development of Publishing Strategies in a Competitive International Market
Authors: Pantin Isabelle 
Published: April 2022

AbstractIn the first half of the sixteenth century, the printing of mathematical books in Paris developed rapidly. Parisian printers were able to sell their productions to a sufficient local market, and even to achieve such quality as to become attractive at a European level. They achieved this quality with printing houses that could afford to be equipped with all necessary material, but their chief asset was collaboration with skilled teachers and mathematicians who had a talent for innovation. This article first analyzes the Parisian book market in the European context and examines ways we can evaluate the circulation of Parisian mathematical books. Then it focuses on the career and practices of Guillaume Cavellat (ca. 1500–1576), who devoted the main part of his activity to the publication of mathematical books. The network of his scientific collaborators, both inside and outside the University of Paris, was a crucial factor in his prolonged success. Lastly, the essay discusses the impact of the quality of the layout and illustration on the capacity of mathematical books to circulate, and to attract attention and customers, across a wide area: Did the emergence around 1540 of a “Parisian style,” with unique features from the beauty of the books as material objects to their efficiency as learning and thinking tools, contribute to the visibility and attractiveness of Parisian mathematical books in the European market?
Energy-Efficient Internet of Things Solution for Traffic Monitoring
Authors: Hoch Thomas , Kopetzky Theodorich 
Published: April 2022

AbstractRecent progress in video-based vehicle sensors allows for a detailed observation of road users on intersections in urban areas. By combining the measured real-life traffic situation with thorough traffic simulations, a cooperative system design for the dynamic management of traffic flow including vehicle platoons is possible. In this chapter, we describe our video-based traffic flow estimation system that we installed at a three-way intersection in the small city of Hallein, Austria. We show that the installed system is able to collect comprehensive information about the traffic situation in near real time, and that this information can be used to estimate traffic density and flows of cars and trucks with high precision.
Road Safety Issues Related to Truck Platooning Deployment

Published: April 2022

AbstractThe benefits of platooning to road safety are oftentimes inferred based on the assumption of positive effects attributed to advanced driver assistance systems (ADAS). However, the potential to significantly reduce car crashes is just one of many aspects to be considered. The Connecting Austria project was committed to examining road safety issues from various perspectives within Austria. The legislative situation in Austria regarding public tests of automated driving systems was reviewed and requirements discussed. Furthermore, an assessment of the readiness of 700 km road infrastructure was assessed by means of an adapted Road Safety Inspection and recent heavy goods vehicle (HGV) accident figures on motor and expressways were discussed. Eventually, the distance at which HGV should operate cooperatively is a road safety issue demanding for consideration of other road users. Car drivers’ subjective tolerance of gap sizes between trucks can serve as an important indicator to answer this question. An on-road study aiming at operationalising the individual gap acceptance is outlined.

Published: April 2022

AbstractEmerging technologies may trigger rethinking existing business models, clearly highlighting economic benefits and analysing effects on innovation systems. Truck platooning as one emerging technology in the area of road freight transport promises to improve efficiency and safety and requires different stakeholders (e.g. road operators, freight forwarders, truck manufacturers, etc.) to adapt their business models. In this chapter, key aspects when developing a truck platooning business model from a road operator’s perspective will be summarised based on related work and interviews/workshops conducted in the Connecting Austria project. Furthermore, the relevance of ongoing trend monitoring to continuously adapting business models is discussed in this chapter and applied for logistics and automated driving within the Connection Austria consortium.
Discussion

Published: April 2022

AbstractIn 2017, the Connecting Austria project was internationally unique with respect to the special consideration of the infrastructure and traffic perspective as well as the special consideration of investigating an urban truck platooning use case with traffic-light-controlled intersections before and after motorway entrances. The three main target groups of the project were: (1) road operators/infrastructure providers, (2) logistics operators and (3) C-ITS industry. Especially for those target groups and policy maker faced one central question at that point in time —“How can safe truck platooning reduce CO$$_{2}$$

-emissions and how can this help to strengthen the stakeholders’ role in their market or political environment?”. Cooperative, connected and automated mobility shape the future of road transport. Thereby, truck platooning represents an important application case in the transport logistics domain. In this chapter, the research and evaluation results presented in this book are discussed along the following three fundamental pillars: (1) traffic safety and legal issues, (2) sustainability and (3) truck platooning deployment. Finally, limitations and cultural blind spots experienced within international workshops and discussions in the context of the Connecting Austria project are reflected.

AbstractDue to slipstream effects, platooning leads to a significant decrease of the fuel consumption of the heavy-duty vehicles (HDV). Measurements with a platoon consisting of three vehicles were performed at the Zalazone proving ground. The goal of these measurements was to get the static pressure at the front and the rear of the second vehicle to calibrate computational fluid dynamics simulation and to measure the fuel consumption directly. Measurements were done at a vehicle speed of 80 km/h and varying inter-vehicle distances. Platooning leads to a reduction of the pressure coefficients in the centre of the HDV front and an increase of the pressure coefficient at the top and the rear of the HDV. Furthermore, a reduction of the fuel consumption of the leading vehicle of 7.9% at an inter-vehicle distance of 6 m and 3.7% at a distance of 22 m was determined. A comparison to CFD simulation showed a similar fuel reduction for an inter-vehicle distance of 6 m and 22 m. CFD simulation showed an increase of fuel consumption at an inter-vehicle distance of 15 m. This increase was experimentally not validated. Also, results for the following vehicle are presented.
Platoon Control Concepts

Published: April 2022

AbstractCooperative platoon control strategies utilise provided information from vehicle-to-everything (V2X) communication to reduce energy consumption and improve traffic flow and safety. In this chapter, a distributed control concept for cooperative platooning is developed that combines trajectory optimisation and local model-predictive control of each vehicle. The presented control architecture ensures collision safety by design, platoon efficiency and situational awareness with the option of exploiting V2X communication. The resulting platoon control performance is tested and validated in a realistic setting by utilising a co-simulation-based validation framework with detailed vehicle dynamics.
Legal Preconditions for an Environmentally Sustainable European Union
Authors: Langlet David 
Published: April 2022

AbstractResilience is increasingly described as a prerequisite for a sustainable EU. Against this backdrop, Langlet looks at the potential of EU environmental law, widely construed, to create and maintain conditions for environmental resilience, and thereby support the realization of a sustainable society. He does this by assessing to what extent EU law has some of the characteristics widely considered key to the successful management of social-ecological systems. Among these are the ability to generate knowledge on the state of the environment, formulate relevant management objectives, pursue management at relevant scales, as well as ability to adapt in light of changing conditions and new knowledge. Langlet finds that although EU law has gradually developed the desired characteristics, much remains to be done for example in terms of integrating environmental considerations into other policy areas. The EU also remains highly dependent on the resources and capabilities of individual member states for both know-how and policy measures.
Technical Considerations for Cardiac PET/CT

AbstractPositron emission tomography (PET) is a non-invasive imaging technique that employs positron-emitting radionuclides labelled to biological molecules. Unlike other imaging techniques, such as computer tomography (CT) and magnetic resonance imaging (MRI) that provide anatomical or structural information, PET allows obtaining unique quantitative information of important biologic processes in vivo (e.g. myocardial perfusion and metabolism, inflammation, innervation, receptor density).

AbstractThe use of PET/CT hybrid imaging in ischemic heart disease, integrating information from PET and CT, has grown in the last decade, particularly because of its capacity of quantifying myocardial perfusion, allowing the assessment of myocardial blood flow (MBF) and myocardial flow reserve (MFR). This feature makes PET/CT the technique best suited to detect multivessel coronary artery disease which might not be identified with SPECT due to its inherent limitation in cases of balanced ischemia. Additionally, the CT component of these hybrid imaging systems allows calculation of coronary artery calcium score (ChACS) and the visualization of the epicardial coronary arteries with coronary CT angiography (CCTA). PET/CT has therefore a great potential in the diagnosis and management of CAD. This chapter will cover several clinical cases, illustrating many different clinical applications in ischemic heart disease.

Published: April 2022

Abstract
Purpose
Negative life events (LEs) are associated with mental health problems in youth. However, little is known about underlying mechanisms. The aim of the study was to investigate whether exposure to LEs modifies stress sensitivity in youth’s daily life.

Methods
Ecological Momentary Assessment (EMA) was used to assess stress sensitivity (i.e., association of momentary stress with (i) negative affect and (ii) psychotic experiences) in 99 adolescents and young adults (42 service users, 17 siblings, and 40 controls; Mage 15 years). Before EMA, exposure to LEs (e.g., intrusive threats, experience of loss, serious illness) was assessed.

Results
Lifetime as well as previous-year exposure to LEs modified stress sensitivity in service users: they experienced more intense negative affect and psychotic experiences in response to stress when high vs. low exposure levels were compared. In contrast, controls showed no differences in stress sensitivity by exposure levels. Looking at specific types of LEs, controls showed less intense negative affect in response to stress when high vs. low exposure levels to threatening events during the last year, but not lifetime exposure, were compared. In siblings, no evidence was found that LEs modified stress sensitivity.

Conclusion
Stress sensitivity may constitute a putative risk mechanism linking LEs and mental health in help-seeking youth, while unfavourable effects of LEs on stress sensitivity may attenuate over time or do not occur in controls and siblings. Targeting individuals’ sensitivity to stress in daily life using novel digital interventions may be a promising approach towards improving youth mental health.
Continuous table tennis is associated with processing in frontal brain areas: an EEG approach
Authors: Visser Anton , Büchel D. , Lehmann T. , Baumeister J. 
Published: April 2022

AbstractCoordinative challenging exercises in changing environments referred to as open-skill exercises seem to be beneficial on cognitive function. Although electroencephalographic research allows to investigate changes in cortical processing during movement, information about cortical dynamics during open-skill exercise is lacking. Therefore, the present study examines frontal brain activation during table tennis as an open-skill exercise compared to cycling exercise and a cognitive task. 21 healthy young adults conducted three blocks of table tennis, cycling and n-back task. Throughout the experiment, cortical activity was measured using 64-channel EEG system connected to a wireless amplifier. Cortical activity was analyzed calculating theta power (4–7.5 Hz) in frontocentral clusters revealed from independent component analysis. Repeated measures ANOVA was used to identify within subject differences between conditions (table tennis, cycling, n-back; p < .05). ANOVA revealed main-effects of condition on theta power in frontal (p < .01, ηp2 = 0.35) and frontocentral (p < .01, ηp2 = 0.39) brain areas. Post-hoc tests revealed increased theta power in table tennis compared to cycling in frontal brain areas (p < .05, d = 1.42). In frontocentral brain areas, theta power was significant higher in table tennis compared to cycling (p < .01, d = 1.03) and table tennis compared to the cognitive task (p < .01, d = 1.06). Increases in theta power during continuous table tennis may reflect the increased demands in perception and processing of environmental stimuli during open-skill exercise. This study provides important insights that support the beneficial effect of open-skill exercise on brain function and suggest that using open-skill exercise may serve as an intervention to induce activation of the frontal cortex.
