Bridge networks are essential components of civil infrastructure, supporting communities by delivering vital services and facilitating economic activities. However, bridges are vulnerable to natural disasters, particularly earthquakes. To develop an effective disaster management strategy, it is critical to identify reliable, robust, and efficient indicators. In this regard, Life-Cycle Cost (LCC) and Resilience (R) serve as key indicators to assist decision-makers in selecting the most effective disaster risk reduction plans. This study proposes an innovative LCC–R optimization framework to identify the most optimal retrofit strategies for bridge networks facing hazardous events during their lifespan. The proposed framework employs both single- and multi-objective optimization techniques to identify retrofit strategies that maximize the R index while minimizing the LCC for the under-study bridge networks. The considered retrofit strategies include various options such as different materials (steel, CFRP, and GFRP), thicknesses, arrangements, and timing of retrofitting actions. The first step in the proposed framework involves constructing fragility curves by performing a series of nonlinear time-history incremental dynamic analyses for each case. In the subsequent step, the seismic resilience surfaces are calculated using the obtained fragility curves and assuming a recovery function. Next, the LCC is evaluated according to the proposed formulation for multiple seismic occurrences, which incorporates the effects of complete and incomplete repair actions resulting from previous multiple seismic events. For optimization purposes, the Non-Dominated Sorting Genetic Algorithm II (NSGA-II) evolutionary algorithm efficiently identifies the Pareto front to represent the optimal set of solutions. The study presents the most effective retrofit strategies for an illustrative bridge network, providing a comprehensive discussion and insights into the resulting tactical approaches

Sensors and Actuators A: Physical 2025年 390卷

作者： Shimooka, So Tadachi, Kazuma Kamegawa, Tetsushi Faculty of Environmental Life Natural Science and Technology Okayama University 3-1-1 Tsushima-naka Kita-ku Okayama Japan Mechanical and Systems Engineering Program School of Engineering Okayama University 3-1-1 Tsushima-naka Kita-ku Okayama Japan

In this study, we propose an extension-type flexible pneumatic actuator (EFPA) with a high extension force and no buckling. In a previous study, soft actuators that extended in the axial direction by applying a supply pressure were unable to generate the extension's pushing force because the actuators buckled owing to their high flexibility. To generate a pushing force, the circumferential stiffness of an extension-type flexible soft actuator must be reinforced. Therefore, a cross-linked EFPA (CL-EFPA) was developed, inspired by a pantograph that restrains the EFPA three-dimensionally using the proposed link mechanism. The proposed CL-EFPA consists of three EFPAs and a cross-linking mechanism for integrating each EFPA circumference. The pushing force of the CL-EFPA is approximately 3.0 times compared with that generated by the previous EFPA with plates to restrain its plane. To perform various bending motions, attitude control was performed using an analytical model and a system that included valves, sensors, and controllers. © 2025 The Authors

As public awareness of environmental and health issues grows, providing accurate and accessible environmental risk information is essential for informed decision-making. environmental indices simplify the complex impacts of various environmental factors into a single, interpretable score. The Air Quality Index (AQI) and Air Quality Health Index (AQHI), a widely recognized standard, reflects health risks posed by air pollution but has significant limitations. Conventional index calculations often focus on the single most hazardous pollutant or ignore the combined and cumulative effects of multiple pollutants. Additionally, the commonly used linear and arithmetic approaches can misrepresent actual risks and fail to capture the temporal dynamics of environmental factors. To address these limitations, we propose a deep learning framework for developing a more comprehensive air quality index, the Temporal Air-quality Risk Index (TARI). This framework employs a long short-term memory (LSTM) autoencoder to capture complex interactions and temporal dependencies among environmental factors. By incorporating a risk score (RS) that captures non-linear and continuous risks, TARI provides a more accurate assessment of the environmental impact on health. A case study using real air quality data from South Korea demonstrates that TARI outperforms the Korean Comprehensive Air-quality Index (CAI) and AQHI, exhibiting stronger correlations with disease prevalence. These results highlight TARI's improved sensitivity and relevance in assessing health risks, particularly by addressing cumulative and temporal pollutant effects. To our knowledge, this study is the first to apply deep learning to environmental index development, offering a flexible and robust framework with potential applications across diverse environmental systems. © 2025 Elsevier B.V.

Heavy metal and microplastic pollutions are prevalent in freshwater ecosystems, with many freshwater bodies being contaminated by one or both of these pollutants. Recent studies reported extreme detections of Cd, Pb and Zn, high concentrations of Cr, Pb and Cu and microplastics acting as vectors of pollutants, including heavy metals. Mayflies can serve as bioindicators of heavy metal contamination in freshwater ecosystems because changes in their community structure, physiology, and behaviour can reflect and help predict the concentrations of metals in these environments. This review discusses the ecological alterations induced by tissue metal concentration in mayflies and other macroinvertebrates. As sensitive taxa to heavy metal contamination, mayflies can reflect the impacts of this pollution through their ethology and relationship to the substrate, highlighting issues such as eutrophication, alterations in community structure, inhibitory effects and sediment toxicity. Mayflies are also highly affected by microplastic exposure, which leads to ingestion, bioaccumulation, biomagnification, habitat and community alteration, behavioural changes, physiology alteration and toxicity. Mayflies bioindication metrics for assessing the impact of heavy metals and microplastics include the examination of community alteration, functional feeding behaviour, molecular structure, dietary and toxicity impacts, bioaccumulation and biomagnification and biomarkers. Current challenges for the utilization of mayflies as bioindicators include temporal variations in sensitivity, lack of universally recognised protocols and need for standardised protocols for microplastic analysis. Additionally, the applicability of mayflies as bioindicators may vary across different ecosystems, emphasising the need for selecting suitable indicators that align with the unique characteristics of the ecosystem. © 2024 The Authors

In Central Vietnam, the aggregate typically originates from highly acidic rocks containing a significant amount of silicon dioxide (SiO2), leading to poor adhesion quality with virgin asphalt binder. Hence, the asphalt mixture production usually needs to utilize adhesion promoters. Based on the chemical compositions of the sample aggregate (up to 72.3% SiO2), research has been conducted to introduce an adhesive agent called rubber modified compound (RMC-160), which is composed of styrene-butadiene-styrene (SBS) with petroleum hydrocarbon resin, treated clay and mineral oil. This article presents the research findings regarding the adhesion effectiveness of RMC-160-modified asphalt binder to high acid-based aggregate through laboratory and field tests, along with the mixture performance under both short-term oven aging (STOA) and long-term oven aging (LTOA). The test results exhibited remarkable effects, whereby the asphalt binder modified with RMC-160 additive significantly increased the adhesion level from Grade 2 to Grade 4, and the asphalt mixtures containing RMC-160 had lower rutting and higher cracking tolerance (CTIndex) under both the STOA and LTOA conditions. © 2025 American Society of Civil Engineers.

In the present study, magnetic silica-chitosan hybrid (NMP@SiO₂/CPTMS/Chi) was synthesized via a convenient and green sol-gel technique under room temperature, and the material was used as a highly efficient magnetic adsorbent for the removal of phosphate ions in water. While the magnetic properties of NMP from iron enable the material to be quickly separated via magnetic separation, the abundant active sites from the chitosan made the hybrid exhibit high adsorption capacity for phosphate ions. At pH 6, the removal of phosphate ions followed the pseudo-second-order (PSO) kinetic model with the adsorption rate constant (k₂) of 5.9 × 10^-3 mg g⁻¹ min⁻¹ and obeyed the Langmuir isotherm model with a maximum adsorption capacity (q_max) of 15.06 mg g⁻¹, outperforming most of the previously reported adsorbents. Stability tests and derivative thermogravimetry (DTG) analysis demonstrated that NMP@SiO₂/CPTMS/Chi remained stable even under strongly acidic conditions and possessed high thermal stability, respectively. The synergistic combination of high adsorption capacity, acid stability, thermal stability, and facile magnetic separation renders NMP@SiO₂/CPTMS/Chi a promising adsorbent for wastewater treatment and environmental remediation. Overall, this innovative material represents a significant advancement in phosphate removal, offering a sustainable and effective solution to address the global challenge of water pollution and protect aquatic ecosystems. © 2025 The Authors

The treatment of concentrated landfill leachate generated by nanofiltration and reverse osmosis processes represents a significant challenge. This concentrate is characterized by high concentrations of heavy metals, contaminants of emerging concern, dissolved salts, and organic compounds. In this study, a novel advanced treatment system integrating an Electrocoagulation Reactor with a subsequent electrooxidation process was proposed. Two anode/cathode arrangements were evaluated: electrocoagulation followed by electrooxidation with “boron-doped diamond” and steel electrodes, and electrocoagulation followed by electrooxidation with “boron-doped diamond” and aluminum electrodes, focusing on their effectiveness in degrading contaminants and improving the quality of the treated concentrated landfill leachate. In order to monitor the efficiency of the electrocoagulation process and integrated systems, the degradation of the physicochemical parameters of absorbance at 254 nm, total organic carbon, and turbidity were investigated. Within the best performance, acute toxicity indices (Artemia salina - LC50) were determined and possible degradation and/or formation of contaminants of emerging concern were identified by gas chromatography–mass spectrometry (GC–MS). The results indicated the mineralization of 73 % of total organic carbon and 25 % of total nitrogen, an increase in the biodegradability fraction (BOD5/COD) of the concentrated landfill leachate from 0.18 to 0.35, as well as a significant reduction in toxicity (LC50 of 54.4 %), demonstrated by Artemia salina bioassays. The reduction in toxic potential was also observed in the by-product analysis by GC–MS, which indicated the removal of emerging contaminants such as benzene, 2-(2-methoxy-1-propenyl)-1,3,5-trimethylbenzene, benzothiazole, 2-(methylthio) and phenol, 2,2′-methylenebis[6-(1,1-dimethylethyl)-4-methyl-.

This study proposes a new approach, a communal-based domestic rainwater harvesting (CDRWH) system, which is a new model that combines domestic and communal rainwater harvesting systems. This model is an alternative solution to improve system performance and utilize rainwater overflow from the system. Rainwater runoff from several domestic tanks is channeled to a communal tank to be collected, processed, and redistributed to needy domestic tanks. Overflow from the communal tank is used for groundwater recharge. The CDRWH system model aims to increase water supply, reduce runoff, and conserve groundwater. The model simulation uses daily water balance analysis and yield before spillage algorithm. The simulation scenario uses variations in roof area, number of house occupants, storage tank volume, and rainfall categories: 20 years, wet year, normal year, and dry year. Jagakarsa, an urban area in South Jakarta, was selected for the CDRWH system modeling. The results showed that the CDRWH model significantly improved the performance of the volumetric reliability (VR) and time reliability (TR) systems. In addition, the model could show a comparison of total groundwater recharge (GWR) and groundwater extraction (GWE), where the GWR capacity was higher. This allows centralized rainwater management in communal tanks, thereby reducing groundwater usage. The design of this model is simple. Therefore it can be easily duplicated for application in other locations. © 2025 The Authors

Hemodynamics, the study of blood flow and circulatory forces, is fundamental for assessing cardiovascular health, disease states, and therapeutic outcomes. Here, we introduce a skin-conformable organic optoelectronic thin-film patch (ePatch) designed to simultaneously capture electrocardiography (ECG) and photoplethysmography (PPG) signals as a single hybrid signal, named the electrocardio-photoplethysmogram (EC-PPG). The ePatch integrates an organic electrochemical transistor (OECT), an organic photodiode, surface-mounted light-emitting diodes, and electrochemical electrodes on a flexible, skin-conforming substrate. By training deep learning models on the hybrid EC-PPG data, we achieved accurate arterial blood pressure estimations, with mean errors of just 1.69 mmHg for systolic and 0.89 mmHg for diastolic blood pressure, outperforming traditional predictions that rely on individual physiological signals as inputs. Our findings underscore the potential of EC-PPG as a compound hemodynamic signal for AI-driven vital sign monitoring and integrated, solution-processable soft electronics for clinical and point-of-care applications. © 2025 The Authors

This study presents an investigation of chemical and physical characterization, green process analysis, techno-economic considerations, and carbon emissions for synthesizing metal-organic frameworks (MOFs) from plastic and can waste using microwave-assisted synthesis. The microwave-assisted synthesis proves to be more cost-effective, with a reduction in CO₂ emissions by up to 80%. The synthesized material (MIL-Mw-U) demonstrates excellent performance in methylene blue (MB) removal, achieving 98.41% removal, with 97.87% removal although the catalyst is used in the third cycle. The adsorption of methylene blue (MB) onto MIL-Mw-U achieved a maximum capacity of 295.26 mgg⁻¹ at pH 3 and decreased to 258.68 mgg⁻¹ at pH 11 due to OH⁻ competition. The Langmuir isotherm (R² = 0.9381) and pseudo-second-order kinetics (R² = 0.999) confirmed monolayer chemisorption as the dominant mechanism. This innovative approach supports circular economy principles by converting can and plastic bottle waste into functional material for dye removal, offering sustainable solutions for environmental challenges. © 2025 The Authors
