Structure‐to‐structure seismic damage correlation model
Authors: Xiang Mengjie , Shen Jiaxu , Xu Zekun , Chen Jun 
Published: May 2024

AbstractStrong earthquake disasters can cause noticeable damage correlations among regional buildings with similar mechanical properties, termed structure‐to‐structure seismic damage correlation, which has a pronounced impact on the regional seismic risk assessment and therefore needs to be properly quantified. This study first introduces a time‐domain analytical and equivalent frequency‐domain analysis based on random vibration theory for calculating structure‐to‐structure seismic damage correlation coefficients. Subsequently, by employing the spatially consistent white noise excitation and the spatially varying white noise excitation with the Luco–Wong coherence function, the structural filtering effect and the ground motion spatial correlation effect are progressively incorporated, and an analytical interstructural damage correlation model incorporating structural dynamic properties and spatial distance is derived. Comparations with Monte Carlo simulations and existing empirical models demonstrate that the proposed analytical model possesses a clear physical basis and high reliability. Finally, a case study was conducted on a district having 29,461 buildings in Shanghai, China to illustrate the influence of interstructural damage correlation on the regional seismic risk. Results show that disregarding the interstructural seismic damage correlation can lead to underestimation of overall loss uncertainty.
Effects of incident heat flux on heat release rates and temperatures in cone calorimeter tests of polyurethane foam

Published: May 2024

AbstractThere is great interest in developing methods to predict full‐scale fire performance of mattresses and upholstered furniture for design and regulatory purposes using cone calorimeter and other small‐scale test results. One method used in the past is a model developed during the European Combustion Behavior of Upholstered Furniture (CBUF) project. To support the further development of this model, cone calorimeter tests of polyurethane (PU) foam specimens 5–10 cm thick were conducted using incident heat fluxes between 5 and 35 kW/m2. Temperatures were measured using thermocouples located on the surface and at four depths within 10 cm thick foam specimens to determine the effects of heat flux on heat transfer and foam degradation. Peak and average heat release rate (HRR) values for a particular thickness of foam increased with an increase in heat flux. An increase in heat flux decreased the times to reach the two peaks in the HRR curve, which represent the collapse of foam and burning of liquid products, as well as burning duration. Heat flux had a larger effect on the second HRR peak than the first peak. Significant temperature gradients were initially confined to the top portion of the foam. A surface temperature of 150–200°C was shown to be indicative of the onset of ignition, while a temperature of 150°C at a particular location was indicative of when temperatures began to more rapidly increase at deeper locations within the foam. Infrared video records were also used to examine three‐dimensional burning behavior of the foam.

AbstractIntroductionIn the transition to the postpandemic era, adolescents are working to shift their focus back to school. However, the prevalence of academic procrastination is reflective of that the aftereffects of the pandemic are persisting. Literature documents the increases in the negative parenting behaviors and internet use of adolescents during the pandemic. The excessive internet use has to do with adolescents' self‐regulatory capabilities and self‐regulation is profoundly shaped by parents' parenting practices. Given the connections among these factors, the present study seeks to understand how maladaptive parenting practices during the pandemic influenced adolescents' academic procrastination postpandemic through the mediation of self‐regulation and problematic internet use.MethodUsing three waves of data from a total of 1062 Chinese adolescents (Mage = 14.9 years old, SD = 1.6, 13−18 years old; 45% female), we used structural equation modeling to examine the direct effect of maladaptive parenting on academic procrastination and its indirect effect via self‐regulation and problematic internet use.ResultsMaladaptive parenting during the pandemic did not directly predict adolescent academic procrastination post‐pandemic. Yet, maladaptive parenting indirectly influenced academic procrastination both through self‐regulation solely and self‐regulation and problematic internet use sequentially.ConclusionThe findings demonstrate that parents can contribute to adolescents' academic procrastination by influencing their self‐regulation ability, which further impacts their internet use. Self‐regulation serves as a robust mediator between parenting and adolescents' problematic behaviors related to internet use and learning. Implications for parents and intervention oriented toward adolescents are discussed.

AbstractBackgroundLittle is known about factors that influence footwear selection by field hockey players.MethodsAn online survey was used to collect data on participant demographics and physical characteristics, factors influencing footwear selection, perceptions regarding footwear design features on injury and performance, and experiences regarding usability. Nominal and ordinal data were described as absolute frequencies and relative frequencies. Free text responses were analysed using content analysis. Sex‐related differences in quantitative and qualitative data were explored.ResultsA total of 401 hockey players completed the survey. Participants reported that fit, comfort, support, and cushioning were the most important factors when selecting hockey footwear. Most hockey players believed that stud design could influence athletic performance (65%) and injury risk (63%) but reported having no preference on outsole design or stud shape. Most participants (63%) used hockey‐specific footwear, but 46% of female hockey players did not, with 40% using trail running footwear instead. Qualitative analysis revealed that hockey players, particularly female participants, encounter difficulties finding properly fitting footwear. They desire more options for wide or narrow feet and face challenges in accessing suitable hockey shoes due to limited choices and availability.ConclusionsWith over a third of field hockey players not using hockey‐specific footwear, future research should attempt to understand the reasons and assess the impact of different footwear features on comfort, performance, injury risk, and usability.

Published: May 2024

AbstractThis paper proposes contributions to the efficient wave digital (WD) modeling of large oscillator networks which are emerging as energy‐efficient alternatives to traditional computers. The WD concept enables in‐operando parameter tuning, real‐time testing, and the associated algorithms are highly parallelizable. We present a general electrical model of N‐shaped nonlinearities that are commonly found in nonlinear oscillators. Our model offers the flexibility to design the current–voltage characteristic based on specific requirements. We show how this model can be used to derive efficient and explicit WD algorithms for nonlinear oscillators. Furthermore, we propose the use of lossless transmission lines between the oscillators and the coupling network to obtain an ideal circuit for an oscillator network that can function as an Ising machine and be efficiently and exactly evaluated in the WD domain. The proposed algorithms are compared against the classical method involving iterative techniques, and their capabilities are evaluated through the emulation of a single FitzHugh‐Nagumo oscillator as well as an Ising machine involving transmission lines. In the latter case, we show that, for large networks, the proposed methods decrease the runtime by up to 75% compared to using iterative techniques.

Published: May 2024

AbstractCurrently, tourists consider their satisfaction by keeping in mind their gastronomic experience in the place, especially in destinations with historical and cultural symbolism. This research aims to elaborate an artificial neural network that estimates the changes in the sociodemographic characteristics of gastronomic tourists (gender, age, educational level and income) from questions about motivations, perceptions and opinions about gastronomic tourism. This model can build ‘composite sketches’ or estimations of the profiles based on their replies on the topic incorporated into the artificial neural network model, which can be easily customised by the researcher and is helpful in the development and adaptation of gastronomic tourism products and services. Knowing the relationships between the different opinions, motivations and perceptions that gastrotourists have and their sociodemographic profile is essential to better understand the phenomenon of gastronomic tourism and optimise the management of businesses dedicated to it, as well as public agents promoting local gastronomy.

AbstractPurposeTo validate the New Zealand Anterior Cruciate Ligament (ACL) Registry's capture rate of revisions by cross‐referencing Registry data with reoperations data recorded by the Accident Compensation Corporation (ACC) and identify risk factors for all‐cause reoperation.MethodsPrimary ACL reconstructions performed between April 2014 and September 2019 were individually matched on a record‐by‐record basis between the two databases. The ACC database was used to identify patients who underwent a reoperation with manual review of operation notes to identify whether a revision or other procedure was performed. This was combined with the number of revisions separately recorded in the New Zealand ACL Registry, which was used as the denominator value to calculate the Registry's capture rate of revisions. Patient and surgical data recorded in the Registry were analysed to identify independent predictors for all‐cause reoperation.ResultsA total of 8046 primary ACL reconstructions were matched between the New Zealand ACL Registry and the ACC databases. The reoperation rate was 8.9% (n = 715) at a mean follow‐up of 2.5 years. Meniscal‐related procedures were the most common reoperation (n = 299, 3.7%), followed by revision ACL reconstruction (n = 219, 2.7%), arthrofibrosis (n = 185, 2.3%), cartilage (n = 56, 0.7%) and implants (n = 32, 0.4%). The New Zealand ACL Registry captured 96% of revisions. Younger age (hazard ratio [HR] > 1.4, p < 0.001), earlier surgery (HR > 1.3, p = 0.05), concurrent meniscal repair (medial meniscus HR = 1.9, p < 0.001 and lateral meniscus HR = 1.3, p = 0.022) and hamstring tendon autografts (HR = 1.4, p = 0.001) were associated with a higher risk of reoperation.ConclusionThe New Zealand ACL Registry captured 96% of revisions. Risk factors for all‐cause reoperation included younger age, earlier surgery, meniscal repair and hamstring tendon autografts.Level of EvidenceLevel III.

AbstractReduction in soil salinity in the entire project area is a key indicator of proper functioning of the implemented subsurface drainage (SSD) projects. Electromagnetic induction (EMI) surveys were carried out to facilitate spatiotemporal assessment of soil salinity of a SSD project site in Kahni, Haryana (India). The surveys were conducted in two time frames: immediately after the start of SSD project in 2019 and after 2 years of successful operation in 2021. The collected data of 2 surveys was used to derive a depth‐specific calibrated correlation between the observed salinity (ECe) of collected soil samples and surveyed apparent electrical conductivity (ECa) observations in vertical (ECav) and horizontal (ECah) modes. Spatiotemporal analysis of soil salinity revealed notable changes in areas under different salinity classes over a period of 2 years, indicating the impact of SSD on soil desalinization. During the course of 2 years (2019–2021) of SSD operation, area under moderate salinity (4–8 dS m−1) in the top 0–0.15 m soil increased by 54.5% while it decreased by 40% and 6.6% under high (8–12 dS m−1) and very high (12–16 dS m−1) salinity classes. The rice and wheat yields were also enhanced by 24% and 7% respectively after 2 years operation of SSD in hitherto severally waterlogged saline soils. Overall findings of this study reinforce the scope of using EMI approach to quickly and effectively assess the efficacy of subsurface drainage. Creation of measurable soil salinity maps by proposed EMI and GIS techniques can help in planning and implementing site‐specific management strategies in saline soil reclamation projects.
Harnessing the Dual‐Mode Luminescence of Er/Yb Co‐Doped SrLaLiTeO6 Double Perovskite Phosphors for Remarkably Wide Range Temperature Sensing and NIR pc‐LEDs
Authors: Kaithrikkovil Varriam Pooja , Ganesanpotti Subodh 
Published: May 2024

AbstractThe ever‐increasing demand for efficient and economic photonic materials has hastened the quest for robust, multifunctional phosphors. Herein, a dual‐mode luminescent SrLaLiTeO6:Er3+, Yb3+ double perovskite phosphor whose concentration‐dependent up and down‐conversion luminescence are investigated and underlying mechanisms are discussed. Temperature‐dependent up‐conversion luminescence of 2H11/2→4I15/2 transition exhibits negative thermal quenching, owing to the thermalization process from the 4S3/2 level. Temperature dependent Raman analysis confirms a decrease in the phonon lifetime from 0.43 to 0.28 ps indicating an increased number of phonon decay channels, which explains the rapid thermal quenching of up‐conversion emission at elevated temperatures. The diverse thermal quenching of the thermally coupled levels contributes to the exceptionally high relative sensitivity of 4.49 %K−1 at 140 K. A maximum sensitivity, Sr of 0.84 %K−1 (698 K) is obtained from the Raman‐PL intensity ratio (RPIR) of the band (719 cm−1) and the 986 nm emission band (4I11/2→4I15/2) of Er3+. Hence, by employing multi‐mode temperature sensing techniques a single phosphor can be used for optical thermometry for a broad temperature range from 90 to 698 K. In addition, the Near Infra‐Red (NIR)‐II emission of Er3+ corresponding to 4I13/2→4I15/2 transition shows excellent thermal stability, maintaining 72% of the room temperature intensity at 500 K.

Published: May 2024

AbstractChitosan and pectin are employed here in the formation of biodegradable hydrogels. The addition of cellulose nanowhiskers (CNW) into the hydrogels is accomplished through two methods: by swelling, after the polymeric network formation (Method A), and inclusion in polymer solutions before gelation, with varying CNW content (Method B). Comprehensive physico–chemical, thermal, microscopic, gel fraction, and water vapor transmission analyses are conducted, complemented by antibacterial and viability assessments. CNWs are successfully synthesized and incorporated within the hydrogel by both methods. Moreover, the degradation temperature (Tmax) of hydrogels is higher with CNW (0% CNW: 205.5 °C, 10% CNW: 217.0 °C). CNW aggregates are observed in hydrogels with 20% and 30% content but no aggregation is observed with 4% and 10%. The antimicrobial properties are not affected by the addition of CNW, and the cytotoxicity tests reveal better results with 10% CNW compared with 20%. The study signifies the versatility of CNWs as effective reinforcements, influencing structural, thermal, and biological aspects of the hydrogels. The proposed methodology, emphasizing CNW incorporation, lays the groundwork for innovative biomaterials with promising medical implications. This investigation encourages further exploration and validation of these composite hydrogels in vivo for practical medical use in wound dressings.

Selection of financing and selling modes in a green and capital‐constrained platform supply chain

Published: May 2024

AbstractCurrently, manufacturers can collaborate with online platforms to better sell green products and also finance from platforms to relieve financial pressure. To cater to this trend, we establish a platform supply chain model by considering a manufacturer with capital constraints that invests in a green production program. Then, it can sell green products via the reselling or the agency channel on a platform and finance from a bank, the platform, or both. In this context, we examine the choices of financial strategies and selling channels from the perspectives of both parties, as well as the corresponding environmental benefit and social welfare. Our findings show that the manufacturer prefers bank financing in most cases when the bank's interest rate is smaller than that offered by the platform. However, in the reselling channel, the manufacturer may choose platform financing even if its interest rate is higher. The platform tends to provide the agency channel when the commission rate is within a reasonable range. It is possible to realize the highest environmental benefit and social welfare in specific regions where both parties agree on the financing and selling modes to maximize their profits. When the manufacturer has only partial access to bank financing, it can choose mixed financing. However, the manufacturer cannot always treat mixed financing as a complete replacement of bank financing.
Manufacturer encroachment in a platform supply chain: An analysis of synergy effect, dysergy effect, and mutual exclusivity effect

Published: May 2024

AbstractThe prosperity of internet sales is stimulating a phenomenal growth of retail platforms and manufacturer encroachment. Encroachment spawns channel competition, potentially threatening the platform's profit, which in turn induces a series of countermeasures by the platform. Motivated by this trend, we develop a game‐theoretical model to explore the strategic and tactical interactions between a manufacturer and a platform, in which the manufacturer determines encroachment strategy and quality differentiation tactic, and the platform determines sales mode strategy and information sharing tactic. We find that the manufacturer is profitable and the platform is damaged from encroachment. Furthermore, the manufacturer's quality differentiation tactic can propel the platform to select reselling that indirectly enhances post‐encroachment profitability. In contrast, sales mode and information sharing can be mono or jointly utilized by the platform to counter encroachment. Significantly, we provide a novel inspection method to systematically analyze the cumulative performance of the platform's two countermeasures by introducing the synergy effect, dysergy effect, and mutual exclusivity effect. Interestingly, we highlight that the performance of mono‐countermeasures may be even more effective than that of combined countermeasures to mitigate the platform's loss caused by encroachment. This finding enriches not only the analytic understanding of received wisdom about whether more countermeasures can invariably hold competition edges but also provides useful managerial guidelines for strategic interaction research. Moreover, the manufacturer's increased encroachment capabilities may promote the platform to shift from reselling to agency selling, which reveals that manufacturer encroachment may be a critical factor in the popularity of agency selling.

Published: May 2024

AbstractThis study investigated the potential of electrospun collagen/hyaluronic acid nanofibers for use in biomedicine and skincare. Needleless electrospinning technology employed in the production process resulted in nanofibers with consistent fiber diameters and improved mechanical properties. The composite nanofibers demonstrated impressive tensile strength and elongation capabilities, indicating a favorable interaction between collagen and hyaluronic acid (HA). Cellular assays revealed that the collagen/HA scaffolds facilitated superior cell adhesion and proliferation compared with the control scaffolds, indicating their biocompatibility and potential for tissue engineering. This biomaterial offers an environment‐friendly alternative to conventional skincare products by eliminating the need for preservatives and reducing waste. Although the initial costs are high, the long‐term benefits of material durability and active ingredient efficacy provide compelling cases for industrial adoption. Our findings suggest that collagen/HA nanofibers have the potential to be the next‐generation materials for regenerative medicine and skincare. Further research is required to optimize their production and assess the economic feasibility of skincare and tissue engineering applications.
