Published: May 2024

AbstractThe induced attack on the formation control of multiagent systems is investigated from the perspective of the attacker, where a new induced attack strategy is proposed to drive the whole formation of multiagent systems to the prescribed reference trajectory. Compared with denial‐of‐service attacks and deception attacks, a desired formation reference trajectory with the stable formation structure is reached by the induced attack instead of disrupting the whole formation. First, the induced attack signal is produced by designing an attack generation exosystem, whose dynamics can be described by the regulated attack matrix and can be adjusted to generate the prescribed reference trajectory. Then, based on the local state information, the formation vector, and the induced attack signal among partial agents, a new distributed induced attack formation protocol is proposed, which is composed of the nominal formation term and the induced attack term. Meanwhile, the induced attack design criterion is proposed by utilizing a robust scheme, where the robust performance bound can be configured by two performance regulating parameters and can be used to design the appropriate regulated attack matrix. Furthermore, by establishing the projection of the induced attack signal onto the formation agreement subspace, an explicit expression of the prescribed reference trajectory is determined, which depicts the movement trajectory of the entire formation of the multiagent system under the induced attack. Finally, a simulation is provided to vindicate the effectiveness of theoretical results.

AbstractResearch SummaryCraft firms characterized by a humanistic approach to work face a tension between adhering to pure craft principles and embracing industrialization. This challenge is heightened in family‐controlled craft firms, striving to uphold tradition while adapting to change. This study examines how craft work evolves along the trajectory of entrepreneurial development through a case study of Thun, a third‐generation family craft firm. We identify a set of mechanisms and four configurations—pure, technical, narrative, and ecosystemic—through which craft work evolves over time. These configurations not only preserve traditions, but also infuse them with entrepreneurial spirit, reinterpretation, and deep innovation. This study contributes to the craft work literature by moving beyond static perspectives and revealing the dynamic interplay between different craft configurations.Managerial SummaryCraft firms, which emphasize a humanistic approach to work, often struggle with the tension between preserving traditional craftsmanship and embracing industrialization. Our study of Thun, a third‐generation family craft firm, provides practical insights for managers by identifying a set of mechanisms and four configurations—pure, technical, narrative, and ecosystemic—that show how craft work can evolve over time. Managers can use these configurations to balance tradition and innovation, and inject entrepreneurial spirit into craft processes. Our findings underscore the importance of managing this balance for sustainable competitiveness and fostering an entrepreneurial firm culture that supports both artisanal and industrial production. Our study also provides a practical guide for craft firms seeking to evolve strategically, ensuring the integration of tradition with contemporary entrepreneurial development.

AbstractCurrently, the primary focus for scientific authorities and regulatory departments revolves around water pollution. In this regard, photocatalysis has emerged as a highly effective, affordable, and goal‐oriented approach. Thus, recognizing the urgency of this issue, we focused our efforts towards developing a novel ternary photocatalytic structure based on mesoporous SrSnO3, combined with polypyrrole‐doped carbon black (PPC) and platinum nanoparticles (Pt NPs). Pt NPs, PPC and SrSnO3‐based nanocomposite photocatalyst was developed through a very simple chemical method followed by ultrasonication and photoreduction techniques. XRD analysis confirmed orthorhombic phase of SrSnO3, while the formation of the ternary nanocomposite among Pt NPs, PPC and SrSnO3 has been confirmed by X‐ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared (FTIR) spectroscopy. Transmission electron microscopy (TEM) revealed the presence of Pt NPs (5–15 nm), beads/dense cocoon like structures of PPC along with rod, spherical and needle shape nanostructures of SrSnO3 in newly created ternary photocatalyst. Diffuse reflectance spectroscopy (DRS) showed lowering of band gap energy in case of Pt@PPC/SrSnO3. Newly developed Pt@PPC/SrSnO3 nanocomposite worked efficiently when employed on colorless insecticide imidacloprid (IMD) and on colored methylene blue (MB) dye under UV‐light. Pt@PPC/SrSnO3 photocatalyst exhibited excellent performance with 96.03 % removal of pollutant IMD in only 20 min, almost 296 % more efficient than bare SrSnO3. Furthermore, the Pt@PPC/SrSnO3 ternary photocatalyst showed rapid removal of MB with almost total elimination of dye molecule in just 16 min.

AbstractAn attractive technique for removing CO2 from the environment is sequestration within stable carbonate solids (e. g., calcite). However, continuous addition of alkalinity is required to achieve favorable conditions for carbonate precipitation (pH>8) from aqueous streams containing dissolved CO2 (pH<4.5) and Ca2+ ions. In this study, a pH‐swing process using ion exchange was demonstrated to process 300 L of produced water brine per day for CO2 mineralization. Proton titration capacities were quantified for aqueous streams in equilibrium with gas streams at various concentrations of CO2 (pCO2=0.03–0.20 atm) and at various flow rates (0.5–2.0 L min−1). Energy intensities for the process were determined to be between 30 and 65 kWh per tonne of CO2 sequestered depending on the composition of the brine stream. A life cycle assessment was performed to analyze the net carbon emissions of the technology which indicated a net CO2 reduction for pCO2≥0.12 atm (−0.06–−0.39 kg CO2e per kg precipitated CaCO3) utilizing calcium‐rich brines. The results from this study indicate the ion exchange process can be used as a scalable method to provide alkalinity necessary for the capture and storage of CO2 in Ca‐rich waste streams.

AbstractThe construction of defective sites is one of the effective strategies to create high‐activity Metal–Organic frameworks (MOFs) catalysts. However, traditional synthesis methods usually suffer from cumbersome synthesis steps and disordered defect structures. Herein, a cluster–cluster co‐nucleation (CCCN) strategy is presented that involves the in situ introduction of size‐matched functional polyoxometalates (H6P2W18O62, {P2W18}) to intervene the nucleation process of cluster‐based MOFs (UiO‐66), achieving one‐step inducement of exposed defective sites without redundant post‐processing. POM‐induced UiO‐66 ({P2W18}‐0.1@UiO‐66) exhibits a classical reo topology for well‐defined cluster defects. Moreover, the defective sites and the interaction between POM and skeletal cluster nodes are directly observed by Integrated Differential Phase Contrast in Scanning Transmission Electron Microscopy (iDPC‐STEM). Owing to the molecular‐level proximity between defective sites and POM in the same nano‐reaction space, {P2W18}‐0.1@UiO‐66 exhibits efficient tandem catalysis in the preparation of γ‐valerolactone (γ‐GVL) from laevulinic acid (LA) by the combination of Lewis and Brønsted acids with 11 times higher performance than defective UiO‐66 formed by conventional coordination modulation strategy. The CCCN strategy is applicable to different POM and has the potential to be extended to other cluster‐based MOFs, which will pave a new way for the construction of functional MOFs with multi‐centered synergistic catalysis.

AbstractBackground & AimsSeveral hepatocellular carcinoma (HCC) risk‐models have been developed to individualise patient surveillance following sustained viral response (SVR) in Hepatitis C Virus patients. Validation of these models in different cohorts is an important step to incorporate a more personalised risk assessment in clinical practice. We aimed at applying these models to stratify the risk in our patients and potentially determine cost‐saving associated with individualised HCC risk‐stratification screening strategy.MethodsPatients with baseline F3‐4 fibrosis treated with new oral direct‐acting antivirals who had reached a SVR were regularly followed as part of the HCC surveillance strategy. Six models were applied: Pons, aMAP, Ioannou, HCC risk, Alonso and Semmler. Validation of the models was performed based on sensitivity and the proportion of patients labelled as “high risk”.ResultsAfter excluding 557 with less than 3 fibrosis, 12 without SVR, 18 with a follow up (FU) <1 year, 17 transplant recipients, 16 lost to FU and 31 with HCC at time of antiviral therapy, our cohort consisted of 349 F3‐4 SVR patients. Twenty‐three patients (6.6%) developed HCC after a median FU of 5.12 years. The sensitivity of the different models varied between 0.17 (Semmler7noalcohol) and 1 (Alonso A and aMAP). The lowest proportion of high‐risk patients corresponded to the Semmler‐noalcohol model (5%). Sixty‐three and 90% of the Alonso A and aMAP patients, respectively were labelled as high risk. The most reliable HCC risk‐model applied to our cohort to predict HCC development is the Alonso model (based on fibrosis stage assessed by liver stiffness measurements or Fibrosis‐4 index (FIB‐4) at baseline and after 1 year, and albumin levels at 1 year) with a‐100% sensitivity in detecting HCC among those at high risk and 63% labelled as high risk. The application of the model would have saved the cost of 1290 ultrasound no longer being performed in the 37% low‐risk group.ConclusionIn our cohort, the Alonso A model allows the most reliable reduction in HCC screening resulting in safely stopping life‐long monitoring in about a third of F3‐F4 patients achieving SVR with DAAs.

AbstractWe describe 20 cases of canine pyoderma responsive to immunosuppressive treatments and resembling human pyoderma gangrenosum. All dogs presented with a rapidly evolving, focal to multifocal, painful ulcerative dermatitis, non‐responsive to multiple antibiotic and anti‐inflammatory therapies. Elevations of C‐reactive protein (100%), neutrophilia (75%) and fever (25%) were also present. Histopathology showed a severe, ulcerative, superficial to deep, predominantly neutrophilic dermatitis. Bacterial infection was the most challenging differential diagnosis. Resolution of the lesions was obtained within 4–8 weeks in 83% of dogs treated with ciclosporin. Maintenance treatment was required in the majority of the dogs.
India and the Shanghai Cooperation Organization: In search of a middle ground
Authors: Konwer Shubhrajeet 
Published: May 2024

AbstractThe Shanghai Cooperation Organization (SCO) Summit (2023) in virtual format only exposed the growing disconnect between India and the members of this multilateral framework. Given the precarious state of India's relations with its immediate neighbors, China and Pakistan, and the growing camaraderie between Beijing and Moscow, this article examines the reasons behind New Delhi's continued need to engage with this multilateral framework. While India seeks to use the SCO as a “bridge” to improve its ties with Central Asian nations and act as a “check and balance” within the organization, Beijing's ascendancy as the “primary” external actor in the Af‐Pak and Central Asia region has meant that India's ability to gain advantages from its association with the SCO will be severely limited. As the protracted war in Ukraine continues unabated, India's attempts to find a “middle ground” between competing interests and principles will be put to the test.
Indonesia, an offshore balancer in Southeast Asia?
Authors: Motin Dylan 
Published: May 2024

AbstractObservers generally characterize Indonesia's foreign policy as non‐aligned, hedging between the great powers. Indeed, Indonesian noncommittal behavior and seeming disinterest in regional power politics appear at odds for a country of that size. To explain that puzzle, I apply the concept of offshore balancer, traditionally used to describe British and US foreign policy. An offshore balancer is a state separated from continental politics by a body of water. Theory predicts that an offshore balancer will generally avoid continental commitments when the balance of power is stable. However, it will join the power competition fray if a threatening potential hegemon arises. Offshore balancers turn aggressive only if continental states are so weak that crossing the sea and expanding onshore becomes easy. First, I present the concept and its importance and justify its generalizability through a short overview of American, British, and Japanese foreign policies. Second, I review Indonesian history to check whether its behavior corresponds to that of an offshore balancer. Finally, I lay out what offshore balancing implies for understanding Indonesian foreign policy and its future.
Sustainable biofuel production in Sub‐Saharan Africa: Exploring transesterification process, nonedible feedstocks, and policy implications
Authors: Kichonge Baraka , Kivevele Thomas 
Published: May 2024

AbstractThe world is currently dealing with an energy crisis, primarily due to heavy reliance on finite fossil fuels and the associated rise in energy demand. In response to this crisis, replacing heavy reliance on finite fossil fuels with biodiesel has gained attention as an alternative solution. Sub‐Saharan African (SSA) biodiesel studies have traditionally focused on improving transesterification but overlook socio‐economic, policy, and institutional impacts on production sustainability. To address this gap, this study comprehensively reviews the sustainability of transesterification‐based biodiesel production from nonedible feedstocks in SSA. The study's incorporation of socio‐economic factors, policy considerations, sustainability concerns, and institutional frameworks reveals the complex prospects and challenges facing biodiesel production in SSA. The findings reveal that sustainability challenges in SSA stem from a lack of an integrated approach, resulting in conflicting local and global policies. The study determines that neglecting socio‐economic factors, policy considerations, sustainability concerns, and institutional frameworks weakens regional biodiesel production sustainability. Evidence from the study emphasizes the role of an integrated approach in promoting biofuel production, establishing markets, and improving the livelihoods of the region's population. Furthermore, the review shows that transesterification can yield biodiesel with comparable physical properties to conventional diesel, making it a wide region's favored option.This article is categorized under:

Published: May 2024

AbstractBackgroundAlthough laparoscopy has demonstrated growing applications for either primary colorectal resections or reoperations, no standardized criteria for implementing laparoscopy in revisional surgery have been reported. This study analyzes a single‐center series of major complications after laparoscopic colorectal surgery, undergoing laparoscopic (LR), or open reoperations in compliance with a hemodynamics‐based institutional management.MethodsThis study retrospectively analyzes a series of consecutive patients who primarily underwent either laparoscopic left colectomy or low anterior resection in a tertiary referral center between 2016 and 2021. Major complications requiring reoperation (MCR) were managed through an interdisciplinary protocol and submitted to reoperation according to patient hemodynamics and intra‐abdominal contamination. A cohort analysis primarily assessed treatment failure rates (i.e., 90‐day mortality and need for further surgery), while postoperative morbidity was secondarily examined.ResultsOut of 1137 laparoscopic colorectal resections, 497 patients met eligibility criteria, while 45 (9.1%) developed MCRs were managed according to the standardized interdisciplinary protocol. Revisional surgery was performed through either LR (66.7%) or (33.3%). Treatment failure was 13.3% overall, including additional surgery (11.1%) and 90‐day mortality (6.6%) after reoperation. In both overall and anastomotic leak‐specific MCRs, relaparoscopy resulted in minimized length of hospital stay, postoperative morbidity, and intensity of care.ConclusionsRelaparoscopy for MCR preserves clinical benefits related to minimally invasive colorectal surgery. Further studies should investigate applicative determinants and impediments related to the center volume.

We provide here the first bottom‐up review of the lived experience of mental disorders in adolescents co‐designed, co‐conducted and co‐written by experts by experience and academics. We screened first‐person accounts within and outside the medical field, and discussed them in collaborative workshops involving numerous experts by experience – representing different genders, ethnic and cultural backgrounds, and continents – and their family members and carers. Subsequently, the material was enriched by phenomenologically informed perspectives and shared with all collaborators. The inner subjective experience of adolescents is described for mood disorders, psychotic disorders, attention‐deficit/hyperactivity disorder, autism spectrum disorders, anxiety disorders, eating disorders, externalizing disorders, and self‐harm behaviors. The recollection of individuals’ past histories also indexes the prodromal (often transdiagnostic) features predating the psychiatric diagnosis. The experience of adolescents with mental disorders in the wider society is described with respect to their family, their school and peers, and the social and cultural context. Furthermore, their lived experience of mental health care is described with respect to receiving a diagnosis of mental disorder, accessing mental health support, receiving psychopharmacological treatment, receiving psychotherapy, experiencing peer support and mental health activism, and achieving recovery. These findings can impact clinical practice, research, and the whole society. We hope that this co‐designed, co‐conducted and co‐written journey can help us maintain our commitment to protecting adolescents’ fragile mental health, and can help them develop into a healthy, fulfilling and contributing adult life.

Published: May 2024

AbstractTwo stereoisomers of bicyclic ladder oligosilanes bearing phenyl and tert‐butyldimethylsilyl groups were synthesized, and their structures and electronic properties are compared with a previously reported perisopropyl‐substituted analog. These novel ladder oligosilanes have highly twisted structures with the twist angles between the two terminal Si−Si bonds of av. 37.7 and 39.8°. The UV spectra of these compounds show bathochromically shifted absorption maxima with the longest wavelength compared with that of the perisopropyl‐substituted bicyclic ladder oligosilane. The electronic properties of the ladder oligosilanes were analyzed by theoretical calculations.
Development of a Circularity Assessment Tool with Local Stakeholders from Strasbourg

Published: May 2024

AbstractOur research focuses on the reutilization of construction materials and how we could foster growth in this sector. It deals with the specific case of the re-use sector around Strasbourg, France, providing a comprehensive overview of the local landscape. Indeed, the research was conducted in partnership with the School of Architecture of Strasbourg, the City of Strasbourg, and an engineering consultant called “BOMA” specialized in circular building. This project is supported by the “Campus des Métiers et des Qualifications Eco-construction et Efficacité Energétique Grand Est”, the Grand Est Region, the “Région Académique Grand Est” and the “Banque des Territoires”. To encourage innovative programs around circular economy, we gave particular attention to analysing feedbacks from pilot projects. In addition to the interview with key local stakeholders, a literature review focusing on assessment of circularity in buildings was carried out. Through a methodology developed in a separate scientific paper, we selected 10 key indicators adapted to the area to measure the circularity of a building, focusing mostly on social, environmental, and economical aspects of the project. Thanks to these indicators, a digital tool was developed to calculate the relevant data concerning the circularity of the project, creating analysed feedback of the construction. Five of those indicators have been implemented in this tool, although suggestions have been made to cover more topics. Moreover, in the future, there is the possibility for it to be transformed into a decision-making tool in order to boost the structuration of the re-use sector around Strasbourg.
