Compliance quality improvement and carbon reduction strategies for a fuel vehicle supply chain based on the manufacturer's carbon social responsibility
Authors: Yi Yongxi , Zhang Meng , Li Yuqiong , Wang Yangyang 
Published: July 2023

AbstractIt investigates compliance quality improvement and carbon reduction in the fuel vehicle supply chain. In our model, a manufacturer with carbon social responsibility first determines the level of carbon reduction, vehicle fuel consumption reduction, and compliance quality improvement. Multiple retailers then select the level of marketing effort. The analysis of decentralized, cost‐sharing, and revenue‐sharing decisions shows that the ranking of carbon and fuel consumption reduction and compliance quality improvement under the three models depends on the parameters. Cost‐sharing and revenue‐sharing can improve the utility of supply chain members, but the sharing modes that they prefer are different.
Successfully operating patent digital platforms in China: A configurational perspective
Authors: Liang Kaitong , Ma Lei , Liu Zheng , Yi Chaonan 
Published: July 2023

AbstractThe increasing value of patents for innovation and the permeability of digital technologies have triggered patent digital platforms (PDPs) as a new business model of patent intermediaries. While current literature mainly focuses upon PDPs within a developed country, China shows unique features with a relatively unmatured patent market. This paper aims to explore conditional configurations that lead to the operational success of PDPs throughout China. The results indicate two configurational paths: “firm size driven” and “digital infrastructure and knowledge assets driven.” Furthermore, environmental factors are peripheral conditions yet important. Our findings have enriched the understanding of patent intermediaries in digital age and sheds light on PDP theory and practice.

Published: July 2023

AbstractThis paper presents a pure water antenna with frequency reconfigurability, which is composed of a water resonator, L‐shaped feeder, and metal ground pad. An L‐shaped feeding structure is designed so that the working frequency can be adjusted by changing the water level of the resonator. The cross‐stack periodic water radiator structure improves the radiation efficiency by 2–4 dB compared with simple rectangular structure. The working frequency of this antenna is around 1 GHz, and will decrease by 17 MHz for every 5 mm increase in water level, which proves the feasibility of this antenna for water level monitoring. It has the potential for application in the field of wireless environmental monitoring for the Internet of Things.
A novel method to measure small antennas using a wideband coaxial cone TEM cell
Authors: Ji Rui , Zhou Feng , Yuan Xiuhua , Cheng Kai 
Published: July 2023

AbstractThis paper presents a novel method to measure physically small antennas using a coaxial cone transverse electromagnetic wave (TEM) cell. Due to the ultra‐wideband, large electric field strength, and high dynamic range characteristics, coaxial cone provides a reliable environment to measure parameters such as gain and antenna factor of small antennas. The frequency could cover 200 MHz–40 GHz. To investigate the suitability of the coaxial cone TEM cell to measure antenna, measurements for a wideband small antenna and a horn antenna are carried out. And the validity of this method is verified through comparison of the obtained results, the measurement uncertainty is evaluated. Compared to an anechoic chamber, the space, cost, and time requirements are reduced drastically. Accordingly, this method could be a more effective alternative way to conventional methods such as the three antennas method and the two antennas method using anechoic chambers.

Published: July 2023

AbstractThe goal of therapy in pediatric Hodgkin lymphoma (HL) is to maximize overall survival while minimizing the morbidity of curative therapy. Key findings from recent Children's Oncology Group (COG) trials include: (i) superior event‐free survival with the addition of brentuximab vedotin (Bv) in frontline regimens for high‐risk disease, (ii) successful reduction in myeloablative regimens with demonstrated safety and efficacy of Bv and checkpoint inhibitor therapy in relapsed disease, and (ii) the potential to select a population that can be salvaged after relapse without receiving a stem cell transplant. The COG HL committee will lead a National cancer Institute National Clinical Trials Network phase 3 trial to evaluate the combination of Bv/nivolumab in early‐stage disease. Ongoing advances in technology and blood biomarkers are increasing the ability to deliver biologically driven, personalized treatment for HL.

Published: July 2023

AbstractThe Children's Oncology Group (COG) Bone Tumor Committee is responsible for clinical trials and biological research on localized, metastatic, and recurrent osteosarcoma and Ewing sarcoma (EWS). Results of clinical trials in localized disease completed and published in the past 10 years have led to international standard‐of‐care chemotherapy for osteosarcoma and EWS. A recent focus on identifying disease subgroups has led to the identification of biological features associated with poor outcomes including the presence of circulating tumor DNA (ctDNA) at diagnosis, and specific genomic alterations—MYC amplification for osteosarcoma and STAG2 and TP53 mutation for EWS. Studies validating these potential biomarkers are under way. Clinical trials evaluating the addition of multitargeted kinase inhibitors, which are active in relapsed bone sarcomas, to standard chemotherapy are under way in osteosarcoma and planned in EWS. In addition, the Committee has data analyses and a clinical trial under way to evaluate approaches to local management of the primary tumor and metastatic sites. Given the rarity of bone sarcomas, we have prioritized international interactions and are in the process of forming an international data‐sharing consortium to facilitate refinement of risk stratification and study of rare disease subtypes.
Thermal expansion of high‐density polyethylene in hot plate welding applications
Authors: Novakovic Boris , Kashkoush Mohamed , ElMaraghy Hoda 
Published: July 2023

AbstractThis research studies high‐density polyethylene (HDPE) behavior that is not easily identifiable in a production setting, but is, nevertheless, necessary for consideration when specifying equipment performance for hot plate welding (HPW) applications. Thermal expansion in polymers can depend on several factors, such as the specific type of polymer, its degree of cross‐linking, and the temperature range over which the expansion occurs. This physical behavior can affect the process by prolonging the cycle time if the equipment is not sized correctly for the application. This research uses HDPE samples with different surface areas and varying process parameters (force and temperature) to collect data on the sample size change. Experimental results are compared with a recommended industrial guideline of 0.2 to 0.5 MPa of pressure for the Matching stage (stage for surface conformation). Obtained findings indicate that this industrial guideline is very temperature dependent. Data collected in the experiment were used to develop a mathematical model for thermal expansion under different parameters. This study also presents a visual interpretation of HDPE behavior on the effect of temperature if the pressure is increased or decreased.

Published: July 2023

AbstractThe global COVID‐19 pandemic significantly disrupted educational environments for all students when the majority of schools in the United States abruptly switched to remote learning. School climate, including support and structure, has been recognized as an important construct that influences student functioning. The current study explored student perceptions of school climate before school disruptions as a potential protective factor against negative outcomes during the pandemic. Middle school students (N = 225) completed assessments of their perceptions of school climate in Fall 2019 and self‐reported internalizing symptoms in Spring 2020. Structural equation modeling was used to test both the association and directionality between school climate and internalizing symptoms. Positive perception of school climate before the pandemic was significantly associated with less internalizing symptoms during initial school closures, particularly for girls. The results highlight the importance of school climate in students' mental health, especially during periods of stress. Limitations and future directions are discussed.
Biological Production of Gold Nanoparticles at Different Temperatures: Efficiency Assessment

Published: July 2023

AbstractThe study aims to compare different approaches and efficacies during the biological production of nanoparticles (NPs). Gold nanoparticles (AuNPs) are produced by Fusarium oxysporum at two different temperatures. One flask is incubated at 37 °C (“Common”) and the other is directly heated for 5 min at 80 °C (“Heat‐treated”). Obtained AuNPs are analyzed and compared by spectrophotometry, transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X‐ray spectroscopy (EDS), dynamic light scattering (DLS), and Fourier transform infrared spectroscopy (FTIR). Graphite furnace atomic absorption spectroscopy (GF‐AAS) is used to determine the particle concentration after the AuNPs production. The AuNPs prepared by both (the Common and the Heat‐treated) methods exhibit maximum absorption peaks at 541 and 528 nm, respectively, and have round shapes and sizes of less than 50 nm. Their zeta potential is about −28 mV. GF‐AAS shows that the efficiency of AuNP production in Common‐ and Heat‐treated samples is equal, between 65% and 68%. Since the Heat‐treated sample shows a better size distribution, the use of higher temperature and shorter time period is preferable for the bioproduction of AuNPs. It seems that shortening the time for the production of AuNPs prevents the formation of larger NPs.

AbstractBackgroundHandheld spirometry allows monitoring of lung function at home, of particular importance during the COVID‐19 pandemic. Pediatric studies are unclear on whether values are interchangeable with traditional, clinic‐based spirometry. We aimed to assess differences between contemporaneous, home (unsupervised) and clinic (supervised) spirometry and the variability of the former. The accuracy of the commercially available spirometer used in the study was also tested.MethodsData from participants in the Clinical Monitoring and Biomarkers to stratify severity and predict outcomes in children with cystic fibrosisc (CLIMB‐CF) Study aged ≥ 6 years who had paired (±1 day) clinic and home forced expiratory volume in 1 s (FEV1) readings were analyzed. Variability during clinical stability over 6‐months was assessed. Four devices from Vitalograph were tested using 1 and 3 L calibration syringes.ResultsSixty‐seven participants (median [interquartile range] age 10.7 [7.6−13.9] years) provided home and clinic FEV1 data pairs. The mean (SD) FEV1% bias was 6.5% [±8.2%]) with wide limits of agreement (−9.6% to +22.7%); 76.2% of participants recorded lower results at home. Coefficient of variation of home FEV1% during stable periods was 9.9%. Data from the testing of the handheld device used in CLIMB‐CF showed a potential underread.ConclusionIn children and adolescents, home spirometry using hand‐held equipment cannot be used interchangeably with clinic spirometry. Home spirometry is moderately variable during clinical stability. New handheld devices underread, particularly at lower volumes of potential clinical significance for smaller patients; this suggests that supervision does not account fully for the discrepancy. Opportunities should be taken to obtain dual device measurements in clinic, so that trend data from home can be utilized more accurately.

Published: July 2023

AbstractBACKGROUNDSphodroxia maroccana Ley is a pest of cork oak crops that damages the roots of seedlings and can severely impair cork oak regeneration. Since the banning of carbosulfan and chlorpyriphos, which were widely used against the larvae of Sphodroxia maroccana because of their harmful impact on the environment, until now there has been no pesticide against these pests. Therefore, it is particularly urgent to develop highly effective insecticidal molecules with novel scaffolds. Isoxazolines are a class of insecticides that act on γ‐aminobutyric acid (GABA)‐gated chloride channel allosteric modulators. In this work, a green synthesis of novel 3,5‐disubstituted isoxazoline‐sulfonamide derivatives was achieved in water via ultrasound‐assisted four‐component reactions, and their insecticidal activities against fourth‐instar larvae of S. maroccana were evaluated.RESULTSMost of the tested compounds showed insecticidal activity compared to fluralaner as positive control and commercially available insecticide. Especially, the isoxazoline‐secondary sulfonamides containing halogens (Br and Cl) on the phenyl group attached to the isoxazoline, 6g (LC50 = 0.31 mg/mL), 6j (LC50 = 0.38 mg/mL), 6k (LC50 = 0.18 mg/mL), 6L (LC50 = 0.49 mg/mL), 6m (LC50 = 0.24 mg/mL), 6q (LC50 = 0.46 mg/mL), exhibited much higher larvicidal activity than fluralaner (LC50 = 0.99 mg/mL).CONCLUSIONNovel isoxazolines containing sulfonamide moieties were designed, synthesized and confirmed by two single‐crystal structures of 4e and 6q. Their bioassay results showed significant larvicidal activity with significant morphological changes in vivo. These results will lay the foundation for the further discovery and development of isoxazoline‐sulfonamide derivatives as novel crop protection larvicides of cork oak. © 2023 Society of Chemical Industry.
Reviewing and clarifying the derivation of the hydrostatic primitive equations
Authors: Staniforth Andrew , White Andy 
Published: July 2023

AbstractHaving adopted a spherical geopotential approximation, textbooks generally derive the hydrostatic primitive equations from the fully compressible Euler equations by making three further approximations—usually termed “hydrostatic”, “shallow”, and “traditional”. However, the derivation given by Phillips in 1966 indicates that the traditional approximation is one of the consequences of the consistently applied shallow approximation. This is demonstrated here without recourse to the “vector‐invariant” form of the momentum equation used by him. This new derivation is not only simpler, but also in accord with the known existence of a quartet of dynamically consistent models, depending on whether approximations of shallow and/or hydrostatic type are or are not made in the fully compressible Euler equations in spherical geometry. A brief survey of other derivation strategies is given. To provide further insight, this includes the approximation of Lagrangian density—a scalar quantity—followed by application of either Hamilton's principle or the Euler–Lagrange equations. Relatedly, the consistent specific forms of the spherical geopotential approximation for the (deep) Euler equations and for the (shallow) hydrostatic primitive equations are obtained and discussed. The analysis herein can be generalised to spheroidal geometry. This is of interest, since the Earth is more realistically represented as an oblate spheroid than as a sphere, and opens the way to the development of more accurate dynamical cores for global atmospheric and oceanic modelling.
Adaptive finite time command filtered backstepping control design for a class of uncertain full state constrained strict‐feedback nonlinear systems
Authors: Soukkou Yassine , Tadjine Mohamed , Nibouche Mokhtar 
Published: July 2023

AbstractThis article investigates an adaptive finite time command filtered backstepping control design for a class of uncertain full state constrained strict‐feedback nonlinear systems. The proposed adaptive control strategy is constructed by combining the barrier Lyapunov functions (BLFs), the adaptive command filtered backstepping control method and the finite time control theory. The BLFs are utilized to overcome the violation of the full state constraints. The proposed adaptive control approach is introduced to avoid the problem of the explosion of complexity and the compensating signals are designed to eliminate the influence of the filtering errors caused by the command filters. Moreover, based on the Lyapunov stability theory, it is proved that all the signals of the closed‐loop system are practical finite time stable and the full state constraints are not violated. To verify the efficiency of the proposed adaptive control scheme, simulation results are provided for electromechanical system.

AbstractPhotonic actuators, serving as an emerging kind of intelligent stimuli‐responsive material, can exhibit the abilities to change their structural colors/fluorescence and shapes under specific external stimuli, which have demonstrated essential applications in the fields of intelligent soft robotics, sensors, bionics, information storage, anti‐counterfeiting, and energy harvesting. In this review, we reported the state‐of‐the‐art research progress of stimuli‐responsive photonic actuators classified on the basis of the material type and focusing on the actuation mechanisms, design principles, and processing techniques. We also broadly summarized the relative applications of photonic actuators in bionics, intelligent robots, sensors, and so on. Finally, a vision for the challenges in the area and future promising directions of stimuli‐responsive photonic actuators is presented.
Global lessons from local actions: A typology of polish local government approaches to sustainable development
Authors: Boguszewski Rafał , Piłat Adam , Węgrzyn Paweł 
Published: July 2023

AbstractOur study aimed to distinguish between different groups of local governments using two dimensions: awareness and commitment to sustainability. Our survey addressed all local governments in Poland, and the survey response rate was close to 25% (N = 718). In the first step, we analysed the dimensions of local governments committed to sustainability, which local authorities attribute importance to. In the next step, we created an index of awareness of the importance and an index of local government's involvement in activities for sustainable development. The combination of the awareness and involvement indices allows distinguishing three separate groups (clusters) of local governments: those that are aware and involved (22.2% of the total), those that are aware and not involved (39.5%) and those that are unaware and not involved (38.3%). Moreover, the empirical results show a relationship between the financial situation of local governments and their allocation to a particular cluster.
From Material to Cameras: Low‐Dimensional Photodetector Arrays on CMOS

Published: July 2023

AbstractThe last two decades have witnessed a dramatic increase in research on low‐dimensional material with exceptional optoelectronic properties. While low‐dimensional materials offer exciting new opportunities for imaging, their integration in practical applications has been slow. In fact, most existing reports are based on single‐pixel devices that cannot rival the quantity and quality of information provided by massively parallelized mega‐pixel imagers based on complementary metal‐oxide semiconductor (CMOS) readout electronics. The first goal of this review is to present new opportunities in producing high‐resolution cameras using these new materials. New photodetection methods and materials in the field are presented, and the challenges involved in their integration on CMOS chips for making high‐resolution cameras are discussed. Practical approaches are then presented to address these challenges and methods to integrate low‐dimensional material on CMOS. It is also shown that such integrations could be used for ultra‐low noise and massively parallel testing of new material and devices. The second goal of this review is to present the colossal untapped potential of low‐dimensional material in enabling the next‐generation of low‐cost and high‐performance cameras. It is proposed that low‐dimensional materials have the natural ability to create excellent bio‐inspired artificial imaging systems with unique features such as in‐pixel computing, multi‐band imaging, and curved retinas.
