Published: January 2024

AbstractThis article investigates the fault‐tolerant formation containment control of multi‐agent systems with actuator and sensor faults. First, adaptive descriptor observers are proposed for the followers to estimate system states, actuator faults, and sensor faults simultaneously. Then, distributed fault‐tolerant formation containment controllers are designed based on the estimated values and sufficient conditions for the formation containment control are identified using Lyapunov method in the time domain. Finally, the effectiveness and advantages of the proposed method are demonstrated through numerical simulations.
Nonlinear predictor‐feedback cooperative adaptive cruise control of vehicles with nonlinear dynamics and input delay
Authors: Bekiaris‐Liberis Nikolaos 
Published: January 2024

SummaryWe construct a nonlinear predictor‐feedback cooperative adaptive cruise control (CACC) design for homogeneous vehicular platoons subject to actuators delays, which achieves: (i) positivity of vehicles' speed and spacing states, (ii) string stability of the platoon, (iii) stability of each individual vehicular system, and (iv) regulation to the desired reference speed (dictated by the leading vehicle) and spacing. The design relies on a nominal, nonlinear adaptive cruise control (ACC) law that we construct, which guarantees (i)–(iv) in the absence of actuator delay, and nonlinear predictor feedback. We consider a classical (for ACC/CACC design) third‐order, nonlinear model subject to input delay, for the vehicles' dynamics. The proofs of the theoretical guarantees (i)–(iv) rely on derivation of explicit estimates on solutions (both during open‐loop and closed‐loop operation), capitalizing on the ability of predictor feedback to guarantee complete delay compensation after the dead‐time interval has elapsed, and derivation of explicit conditions on initial conditions and parameters of the nominal control law. We also present consistent simulation results, considering a platoon of ten vehicles, which validate the design developed.
Less‐conservative reduced‐order interval estimation: A new two‐step approach
Authors: Wang Zhenhua , Zhang Fan , Meslem Nacim , Raïssi Tarek , Shen Yi 
Published: January 2024

AbstractThis article proposes a two‐step interval estimation method for continuous‐time linear time‐invariant systems with unknown but bounded disturbances and measurement noise. In the first step, method is used to design a robust reduced‐order observer that attenuates the impact of the system uncertainties on the estimation error. In the second step, a non‐conservative interval prediction of the estimation error is achieved by applying a symmetric set‐integration approach. The resulting tight set‐valued state estimation is obtained by combining the point estimation from the reduced‐order observer with the predicted estimation error set provided by the set‐integration method. Compared to the conventional methods, the proposed method is built on less‐restrictive design conditions, that allow one to deal with a large range of applications. On the other hand, numerical simulations show that the proposed method offers more precise interval estimation compared to an optimal reduced‐order interval observer selected from recent literature.

Published: January 2024

AbstractIntrinsically stretchable electronics have gained extensive interest recently, due to their promising application in wearable electronics, bio‐integrated electronics, and healthcare devices. All of the components of such stretchable electronics need to be stretchable and mechanically robust to accommodate complex movements. The design and fabrication of robust intrinsically stretchable electronic materials represent a critical challenge in this emerging field. In this review, we focus on the latest studies of intrinsically stretchable electronics, covering the strategies for achieving intrinsically stretchable electronic materials, the recent progresses in the key electronic materials including intrinsically stretchable conductors, semiconductors, dielectrics, and the devices produced by them. Finally, some suggestions and prospects for the future development of intrinsically stretchable electronics are proposed.
Transportation networks and competition in the market for corporate control
Authors: Testoni Marco 
Published: January 2024

AbstractResearch SummaryWhile competition in the market for corporate control determines firms' ability to capture value from acquisitions, there is limited evidence of factors that influence such competition. This study explores whether airline routes intensify competition in this market and affect the target's returns. Targets can become better connected to distant latent acquirers (DLAs), which can increase the targets' bargaining power. Similarly, better connectivity can allow acquirers to reach distant latent targets (DLTs) and therefore increase the acquirers' bargaining power. Examining acquisitions between US public companies during 1980–2018, I find that lower travel time between the target and its DLAs increases the target's returns and the number of competing bids. Instead, the travel time between the acquirer and its DLTs does not play a role.Managerial SummaryIn corporate acquisitions, the competitive threat posed by potential alternative acquirers of the target generally forces the focal acquirer to offer high returns to the target to gain its control. Indeed, these transactions are often not profitable for acquirers. Yet, we know little about what determines the competitive threat faced by acquirers in the market for corporate control. This study shows that the presence of airline routes that reduce the travel time between the target and its latent acquirers increases the target's returns from the deal and the number of competing bids. The study also tests whether lower travel time between the acquirer and its latent targets gives the acquirer more bargaining power vis‐à‐vis the focal target. However, there is no evidence of this effect.

Published: January 2024

AbstractIn living organisms, carotenoids are incorporated in biomembranes, remarkably modulating their mechanical characteristics, fluidity, and permeability. Significant resonance enhancement of Raman optical activity (ROA) signals of carotenoid chiral aggregates makes resonance ROA (RROA), a highly selective tool to study exclusively carotenoid assemblies in model membranes. Hence, RROA is combined with electronic circular dichroism (ECD), dynamic light scattering (DLS), molecular dynamics, and quantum‐chemical calculations to shed new light on the carotenoid aggregation in dipalmitoylphosphatidylcholine (DPPC) liposomes. Using representative members of the carotenoid family: apolar α‐carotene and more polar fucoxanthin and zeaxanthin, the authors demonstrate that the stability of carotenoid aggregates is directly linked with their orientation in membranes and the monomer structures inside the assemblies. In particular, polyene chain distortion of α‐carotene molecules is an important feature of J‐aggregates that show increased orientational freedom and stability inside liposomes compared to H‐assemblies of more polar xanthophylls. In light of these results, RROA emerges as a new tool to study active compounds and drugs embedded in membranes.

Published: January 2024

AbstractMacrophage dysfunction is one of the primary factors leading to the delayed healing of diabetic wounds. Hypoxic bone marrow mesenchymal stem cells‐derived exosomes (hyBMSC‐Exos) have been shown to play an active role in regulating cellular function through the carried microRNAs. However, the administration of hyBMSC‐Exos alone in diabetic wounds usually brings little effect, because the exosomes are inherently unstable and have a short retention time at the wounds. In this study, a multifunctional hydrogel based on gallic acid (GA) conjugated chitosan (Chi‐GA) and partially oxidized hyaluronic acid (OHA) is prepared for sustained release of hyBMSC‐Exos. The hydrogel not only exhibits needs‐satisfying physicochemical properties, but also displays outstanding biological performances such as low hemolysis rate, strong antibacterial capacity, great antioxidant ability, and excellent biocompatibility. It has the ability to boost the stability of hyBMSC‐Exos, leading to a continuous and gradual release of the exosomes at wound locations, ultimately enhancing the exosomes’ uptake efficiency by target cells. Most importantly, hyBMSC‐Exos loaded hydrogel shows an excellent ability to promote diabetic wound healing by regulating macrophage polarization toward M2 phenotype. This may be because exosomal miR‐4645‐5p and antioxidant property of the hydrogel synergistically inhibit SREBP2 activity in macrophages. This study presents a productive approach for managing diabetic wounds.
Solvent‐Triggered, Ultra‐Adhesive, Conductive, and Biocompatible Transition Gels for Wearable Devices

Published: January 2024

AbstractThe development of robust adhesive, conductive, and flexible materials has garnered significant attention in the realm of human‐machine interface and electronic devices. Conventional preparation methods to achieve these exceptional properties rely on incorporating highly polar raw materials, multiple components, or solvents. However, the overexposure of functional groups and the inherent toxicity of organic solvents often render gels non‐stick or potentially biocompatible making them unsuitable for human‐contact devices. In this study, a straightforward three‐step strategy is devised for preparing responsive adhesive gels without complex components. Structurally conductive poly(N‐(2‐hydroxyethyl)‐acrylamide‐co‐p‐styrene sulfonate hydrate) (PHEAA‐NaSS) gels are synthesized by integrating ionic and hydrophilic networks with distinct solvent effects. Initially, the in‐suit formed PHEAA‐NaSS networks are activated by dimethyl sulfoxide, which substantially increases intramolecular hydrogen bonding and enhances the matrix stretchability and interfacial adhesion. Subsequently, ethanol exchange reduced solvent impact and led to a compact network that limited surface exposure of ionic and hydrophilic groups, resulting in nonstick, robust for convenient storage. Finally, upon contacting with water, the network demonstrates rehydration, resulting in favorable adhesion, biocompatibility, and conductivity. The proposed PHEAA‐NaSS/W gels can stably and reliably capture joint motion and electrophysiological signals. Furthermore, this uncomplicated gel preparation method is also applicable to other electrolyte monomers.
Emerging Nanomaterials toward Uranium Extraction from Seawater: Recent Advances and Perspectives

Published: January 2024

AbstractNuclear energy holds great potential to facilitate the global energy transition and alleviate the increasing environmental issues due to its high energy density, stable energy output, and carbon‐free emission merits. Despite being limited by the insufficient terrestrial uranium reserves, uranium extraction from seawater (UES) can offset the gap. However, the low uranium concentration, the complicated uranium speciation, the competitive metal ions, and the inevitable marine interference remarkably affect the kinetics, capacity, selectivity, and sustainability of UES materials. To date, massive efforts have been made with varying degrees of success to pursue a desirable UES performance on various nanomaterials. Nevertheless, comprehensive and systematic coverage and discussion on the emerging UES materials presenting the fast‐growing progress of this field is still lacking. This review thus challenges this position and emphatically focuses on this topic covering the current mainstream UES technologies with the emerging UES materials. Specifically, this review elucidates the causality between the physiochemical properties of UES materials induced by the intellectual design strategies and the UES performances and further dissects the relationships of materials‐properties‐activities and the corresponding mechanisms in depth. This review is envisaged to inspire innovative ideas and bring technical solutions for developing technically and economically viable UES materials.

Published: January 2024

AbstractTo ensure the security of node location privacy in the perception layer of the Internet of Things, this study proposes a location privacy protection method based on RFID location awareness algorithm. This method first introduces an adaptive multi tree anti‐collision algorithm based on collision trees when perceiving and locating the location information of nodes in the perception layer of the Internet of Things, to prevent signal collisions between multiple readers and writers. Then, based on the obtained node location results, a IoT perception layer node location privacy protection scheme based on virtual ring strategy is used to randomly initiate directed co hop routing using the virtual nodes generated after random walking, avoiding the visible area of the source node location, and transmitting data to the aggregation node in the form of the shortest routing path to protect the privacy and security of the node location. Finally, experiments are carried out to prove the progressiveness of the proposed method. The experimental results show that this method can prolong the security period of the source and aggregation nodes in the perception layer of the Internet of Things, protect the privacy and security of node positions, and has great application value.
Anesthesia and humane euthanasia methods for king worm larvae (Zophobas morio)
Authors: Lum Amber M. , Keller Krista A. 
Published: January 2024

AbstractA growing spotlight on insect welfare as research subjects, fodder for vertebrate animals, and patients for veterinarians highlights the need to establish humane euthanasia methods for these species. An insect of increasing commercial importance is the king worm (Zophobas morio), a type of darkling beetle larvae. The initial objective of this study was to determine if prolonged exposure to isoflurane would lengthen anesthetic recovery and lead to euthanasia. Larvae were exposed to isoflurane for 10 min, 40 min, 70 min, 190 min, 13 h, and 24 h (n = 10 for each treatment duration group), and time to recovery was subsequently monitored in room air. The second objective was to determine effectiveness of secondary euthanasia methods: injectable potassium chloride at 1 mg/g body weight (n = 5) and 3 mg/g body weight (n = 5) doses; immersion in 200 proof ethanol (n = 10), 10% buffered formalin (n = 10), and water (n = 10); and freezing at −18°C (n = 10). Prolonged exposure to isoflurane led to extended recovery times, but 100% mortality was not achieved. Submersion in ethanol and injection of potassium chloride at a 3 mg/g body weight dose resulted in 100% mortality. If these larvae are to be used as future food sources, a humane euthanasia method that preserves the ability to be consumed is required.
Managing Constraints and Stories of Freedom: Comparing Cinema Memories from the 1950s and 1960s in Sweden
Authors: Jernudd Åsa , Van Belle Jono 
Published: January 2024

AbstractIn this chapter, cinema memories collected in Sweden from the 1950s—when cinema-going peaked—are compared with ditto a decade later, when attendance had drastically dropped. The comparison is based on 40 interviews divided into two age groups and includes men and women who come from a variety of social backgrounds and who lived in urban as well as rural locations. The selection allowed us to tease out similarities and differences in the memory narratives related to the mentioned intersecting features, to determine whether they had an impact on the rupture of cinema-going. Our results show that gender accounts for the most prominent difference. In the interviews with male participants, delightful memories of childhood matinées are especially salient, and we could only detect slight variation in the memories of this group when we compared the two time periods. In the interviews with female participants, matinées are mentioned only briefly, and we found stark differences in the memory narratives of the two time periods. Cinema-going is remembered by female participants as a special event in the 1950s, while in the memories from the 1960s, it is recalled as a subdued activity in a broader youth culture involving music, dancing, and fashion.
Scenography of the First Intergovernmental Parliament on Education
Authors: Hofstetter Rita , Schneuwly Bernard 
Published: January 2024

AbstractChapters 11, 12 and 13 of Part III analyse the modus operandi of the IBE and its theoretical and methodological underpinnings. This chapter gives a detailed description of the functioning of the International Conferences on Public Education, its scenography which would last, with some adjustments, from 1934 to 1968. Two main topics were discussed in these conferences which are presented and categorised: on the one hand, the educational movement all over the world; on the other hand, international surveys on crucial problems in education. An insert presents a network analysis of some debates in the International Conferences.
“Raising Comparative Education to the Level of Intergovernmental Cooperation”
Authors: Hofstetter Rita , Schneuwly Bernard 
Published: January 2024

AbstractThis chapter describes the conceptual and theoretical background on which the directors of the IBE based their action. Rosselló, deputy director, was a pioneer in comparative education that, for him, was a way of relating the particular with the universal, to draw up international and even universal prospects by taking into account local and regional data. The IBE was a worldwide centre for comparative education, removing any spirit of caste or class. As for Piaget, he transposed his theoretical model of development from egocentrism to reciprocity taking into account the point of view of others. This reciprocity allows “the ascent from the individual to the universal”, to build unity in diversity, universality without uniformity. The insert on the documentation frenzy of the IBE shows another lesser known aspect of IBE activities.
Towards a Universality of Voices
Authors: Hofstetter Rita , Schneuwly Bernard 
Published: January 2024

AbstractChapters 14, 15, 16 and 17 form Part IV, which analyses the IBE’s quest for universality, the difficulties it encountered and the contradictions these led it into. This chapter analyses the complex path towards universality presenting the countries participating in the IBE’s thematic surveys, the drafting of a national report for the Yearbook and the countries represented at the International Conferences. Quantitatively, the IBE was rapidly approaching the goal of universality but large regions were absent due to colonialism. The IBE was aware of the problem but refrained from intervening, always focused on its political neutrality. It was the colonial liberation movement itself that created the conditions for a more effective universality.
Joining the IBE? The Influence of Global Power Relations
Authors: Hofstetter Rita , Schneuwly Bernard 
Published: January 2024

AbstractThe IBE was further away from its goal of universality from the point of view of its affiliated members. Clearly, the Latin and Anglo-Saxon clans that existed in UNESCO, and before that in the ICIC, were echoed within the IBE. As a result, the general orientation of the Bureau would be more strongly marked by a tendency to favour the definition of universalisable principles over a more practical and economic approach. As a consequence, the relatively small number of members often had faced a difficult financial situation, which is presented in an insert.
Teachers: “Architects of the Future of Humanity”
Authors: Hofstetter Rita , Schneuwly Bernard 
Published: January 2024

AbstractThe issues surrounding the teaching profession were also often addressed as causes in themselves. Two issues dominated: teacher training and teacher status and salary. Training for all teachers in higher education institutions was consensual, as was education science, including child psychology, as a reference discipline. The place of national or international orientation in teacher education caused the members of the conference to clash. The conferences steadily advocated for better status and salaries for the teachers, introducing a comparison with other professions with high-level qualifications.
Introduction: Manufacturing Knowledge at the Border of Science
Authors: Crabu Stefano , Neresini Federico , Agodi Maria Carmela , Tosoni Simone 
Published: January 2024

AbstractThis chapter describes the research context and justification for the book. It discusses the relevance of contemporary practices contesting scientific knowledge, with a focus on the COVID-19 pandemic. It introduces the theoretical and methodological background adopted to understand how and under which conditions groups of people assign credibility and trust to knowledge claims located outside the established boundaries of science. In doing so, the chapter proposes an integrated perspective by intersecting the Social Worlds Framework with the major analytical standpoints developed by Actor-Network Theory in the field of science and technology studies. It then describes the content of the various chapters of the book and concludes with their relevance to understanding the ways individuals or groups of people question the legitimacy of science’s claim to define what nature and society are and how societies should be governed.
Conclusion: Is It Really Possible to Take the Floor (Agnostically) About Refused Knowledge?
Authors: Neresini Federico , Crabu Stefano 
Published: January 2024

AbstractThis chapter establishes and underscores the salience and relevance of studying knowledge claims refused by scientific communities as a way to understand the changing relationship between science, technology and society, with its conflicts and ambivalence. It makes the case that studying refused knowledge requires social scientists to venture beyond the comfort zone of their ‘knowing niche’ to renew their analytical lenses and thus avoid simplistic representations and interpretive blind spots. This chapter thus critically scrutinises the implications arising from the permanence of a series of ready-made normative prejudices and interpretative blind spots regarding the current challenges to science as well as about refused knowledge. Finally, it also outlines a number of potential analytical insights that require further collective effort if they are to be better defined and translated into precise research agendas.
